Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a safety ski binding, particularly a heel piece, which has a sole holder that is pivotable about a horizontal axis supported on a support block that can be fixed to a sole plate. , this sole holder is under the action of a release spring which loads the sole holder into the release position, and is held in a sliding state by a locking rocker pivotably supported on the sole holder. The locking rocker has a locking projection on one side which is slidably engaged under a control cam part arranged on the bearing block, and the other side has a locking notch in which at least one spring-loaded web can be engaged at least in a sliding manner, which web can be pivoted into the bearing block at °C. A release gun is supported in the spring casing and is movable in a limited manner relative to the spring casing, and is mounted on the sole holder for purposefully releasing the shoe sole holder. The release lever is provided with a pin connecting the release lever with the spring casing.

Such ski bindings, especially heel pieces, have been commercially available and have been highly valued for several years.
Ru. In such heel pieces, the sole holder and the spring casing are mounted pivotably about a common axis provided in the rear region of the bearing block. When the sole holder is intentionally released by pulling the release lever, it is released from the locking notch of the web or locking rocker, whereby the control cam fixed to the locking rocker or the bearing block is released. The part L is released and the sole holder can actually pivot freely upwards about its pivot axis. However, in this case, after the sole holder is intentionally released, the heel piece does not enter the step-in state, either because the ski boot is re-inserted or the sole holder is closed. requires additional operations.

For example, the release lever is first closed by applying a force, the web is reengaged in the locking notch of the locking rocker, and then the sole holder is pressed down at .degree. However, it is also possible first to close the sole holder, for example by inserting the boot into the sole holder, and then to push the release lever into the closed position and thus the web into the locking notch of the locking rocker.

In the ski binding described in Austrian Patent No. 369,282, the sole holder pivots on an axis remote from the pivot axis of the spring casing, which is arranged in the area above the bearing block. ” It is supported so that it can be rotated.

When the ski binding is in the sliding position, the locking rocker, which is pivotably mounted on the sole holder, engages under a locking lug formed on the bearing block. The locking rocker is loaded by a spring-loaded web supported on the spring housing. The locking rocking body is divided almost entirely, and a pawl is arranged between both parts of the locking rocking body. It is supported on a shaft provided for pivoting support.

The pawl has an actuation attachment loaded by a weak spring. The lower region of the pawl together with the locking rocker forms a locking notch in the spring-loaded web. In order to release the sole holder, the actuating appendage of the pawl must be pressed down against a weak force, the web is released and the spring casing is swung upwards with the aid of the footed spring. . The sole holder is now free to pivot upwards together with the locking rocker, during which the released pawl grips the web again so that it is ready for skiing or stepping. In order to close the heel piece, the sole holder must be pivoted downwards against the force of the release spring. With this heel piece, the sole holder cannot be closed with a small amount of force.

Austrian Patent No. 369,661 discloses an embodiment in which the sole holder and the release lever are pivotable about a common axis which is mounted in the upper region of the bearing block. In this case, the spring housing can, as already mentioned, be pivoted about a pivot axis supported in the lower rear region of the bearing block. In this arrangement, the release lever 2 and the spring casing are connected via a pin, so that intentional release is effected by pivoting the release lever upward. In this design, easy intentional release takes place by changing the relative position between the web and the locking rocker. However, this change in relative position requires that the web be provided with a toothing and that the locking rocker be selectively provided with grooves or teeth corresponding to this toothing, so that the skier bodying of this construction is They are relatively expensive and prone to failure. Moreover, in order to change the relative position, either the locking rocker must be adjustable transversely to the longitudinal axis of the ski winding, or the spring housing must be adjustable in the direction of its pivot axis. This structure also has a high construction cost, so ski windings with this structure have not been sufficiently evaluated to date.

Figures 1 to 4 of Swiss Patent No. 500730
In the figures, an arrangement is disclosed in which the release spring is arranged in a release lever, which is designed as a U-shaped component in plan view. In this case, the release lever and the spring casing are They are substantially the same structural members and are supported so as to be pivotable about a common horizontal axis supported in the bearing block. During the release process, the locking rocker can only perform a pivoting movement; it cannot move upwards. It can pivot around its axis.

Based on the above construction, the release spring must be tightened to the same extent during an intentional release process as during an unintentional release process. Since the anti-swing body is always under the action of the release lever, the sole holder is spring-loaded over the stepping-out snack body.

This known structure therefore does not allow easy step-out.

In a known structure, a tension spring is used as a spring spring. When this return pin (also functions as a casing) is released, this release pin (S) is re-engaged with the locking rocking body.

Make sure that the release spring is not relaxed in any position of the release lever or the release casing force in the known construction.

Rather, the release spring is, for structural reasons, gradually strengthened (tensioned) during intentional release, so that the locking notch Q There is a need to overcome the tensioned state of the release spring.

The object of the invention is to improve the ski-inding of the type mentioned at the outset so that the ski-inding can be brought into a step-in readiness state after a deliberate release;
Moreover, it is possible to collapse the bottom holder and close it again using a force applied to /JS.

According to the invention, this problem is solved by providing a stone ξ in the stationary part of the heel piece, which allows the web to be removed from the locking notch of the locking rocker and the sole holder to be moved between the closed position and the open position. During the intentional release phase between the two positions, the spring casing abuts or contacts the stone ξ in the supporting area, and during the subsequent phase of intentional release the spring casing comes into contact with the sole holder. The solution is that there is no relative movement between the spring casing and the spring casing.

With the arrangement of the invention, upon intentional release of the sole holder by actuating the release lever, the heel piece is automatically brought into step-in readiness. The pivoting movement of the spring casing is limited by the stone ξ, and the spring casing is kept motionless relative to the sole holder. The locking is done in such a way as to be possible without reintroducing the web into the locking hole or activating the release spring, that is to say without any force in practice. The heel piece is closed by simply pivoting the sole holder downwards. However, it can also be closed by hand with significantly less force. For this purpose, the web is again moved away from the locking notch of the locking rocker by pivoting the release lever upwards, and the sole holder is pivoted downwards,
In the next issue, the heel piece will be brought into the closed state by pressing down on the release lever. The heel piece thus has all the advantages of known ski bindings. Moreover, in this case, the operating comfort of the ski binding would additionally be significantly improved.

A particularly advantageous and simple embodiment of the invention is characterized by
ξ is formed by the pivot axis of the sole holder which is supported on the bearing block. This makes it unnecessary to use a special part as a stop and to fix this part in the region of the fixation of the heel piece, for example in the bearing block.

According to a feature of a further embodiment of the invention, a support area for the spring housing is provided on the cover of the spring housing, and this support area is advantageously designed to be elastic. In this way the spring casing can be used to form a corresponding stop without major changes in the heel piece.Furthermore, in this case an additional spring can be used to help return the spring casing. It can be placed and installed.

According to an advantageous embodiment of the invention, the support area of the spring housing is designed as an elastic tongue, for example a leaf spring, pointing towards the interior of the ski binding. In this embodiment, the arrangement of the support region in the spring housing, which is designed as a spring, is particularly simple. Furthermore, this spring is tensioned after the pivoting movement of the spring housing when it comes into contact with the strut. The spring is thus relaxed both in the sliding state and in the first stages of unintentional release and intentional release, so that there is no need to overcome this spring force.

Another object of the invention is to further simplify the configuration. In this case, the manufacturer has a great deal of choice regarding the configuration of the internal area of the heel piece and
It is desired that large tolerances be allowed for configuration and placement between ξ and the support area of the cover.

According to the invention, the object is such that the support block ξ is formed by the rear free end of the retaining plate or the bottom plate of the bearing block, or is provided on one of said plates, so that the supporting area of the spring casing is not limited to the release lever. It is formed by a forwardly projecting extension of the rear end region of the cover which covers the connected spring casing.

This configuration simplifies the construction, which also provides manufacturing advantages. Moreover, in this case a simple design of these ranges is possible. In addition, large tolerances can be obtained for ℃ without affecting the mode of action. The heel piece can be constructed particularly easily without major modifications to configure the stone ξ. Another possibility is provided for arranging an additional spring to assist in the return of the spring casing. In this case, this spring is easy to replace. This allows the spring characteristics to be changed or changed as needed. You can easily replace broken springs.

A further embodiment of the invention is characterized in that the stop is supported elastically, for example via a spring, in the end region of the bottom plate or the bearing block and is preferably slidably guided in this region. That's true.

In this embodiment, the elastically supported stone ξ or its spring is particularly simple. Moreover, this spring is only tensioned after the pivoting movement of the spring housing when it rests on the stone ξ. As a result, the spring is relaxed both in the sliding state, during unintentional release, and during the first stage of intentional release, so that there is no need to overcome this spring force.

According to a further embodiment of the invention, the stone ♀ is constructed in one piece with the bottom plate or with the retaining plate of the bearing block. This configuration is advantageous for manufacturing reasons. Of course, this arrangement can also be used if, according to another feature of the invention, the extension of the cover is supported elastically on the stop, for example with a rubber or plastic spring.

The elastic support area of the elastic tongue or extension on the cover can be manufactured in one piece with the cover. This procedure provides additional manufacturing advantages.

Another embodiment of the present invention is characterized in that the locking oscillating body holding slider shaft is supported in two elongated holes provided in the side wall of the release lever concentrically with respect to the pivot axis of the sole holder. , the release lever is supported from above on the pivot axis of the sole holder and has a recess in the form of a cutout for each pin which is fixed to the sole holder or to the release lever; It is. With this configuration of the present invention, the heel piece can be intentionally released by pushing it down toward the release lever or by pulling it.When releasing the heel piece, the shaft holding the locking rocker rotates around the release lever. The pivot shaft of the sole holder acts as a pivot shaft for the release lever when the shoe is pressed down and released.In this case, the relative movement between the locking rocker holding rocker shaft and the release lever is released. This is made possible by both slots in the lever; in both cases the heel piece is ready to step in after intentional release.

In one embodiment of the present invention, the supporting range of the release lever relative to the pivot axis of the sole holder is rounded to correspond to the radius of the pivot axis. This will provide a good distribution of force upon depressing and releasing.

In this embodiment, in order to be able to close the sole holder from the released position with a slight force,
According to a further embodiment of the invention, the pivot range of the release lever defined by the two elongated holes in the release lever can be brought out of action by a deliberately actuated locking member. te℃・ru. This allows the heel piece to be closed during the action of the locking element with a small amount of force, as already mentioned.

According to one embodiment of the invention, this locking member is formed by a spring-loaded slide, which is mounted on the release lever so as to be movable in its longitudinal direction. The slider has a manually grippable activation projection at one end and at least one hook-like gripping member at the other end, which grips the slider by actuating it. I started to grab the shaft of the stop-swinging body (・ro.

Furthermore, the locking member, which can be easily installed, is a spring-loaded slider mounted on the release lever so as to be movable in its longitudinal direction, and has a hand-gripable slider at one end. It has an operating protrusion, the other end is split into a fork shape, and it has two support members extending on the sides of the locking rocker, and these support members actuate the slider to move the locking rocker. It can be constructed by being provided under the axis of the moving body and supporting the engaging arm rocking body from below.

What is also important for the invention is the force of an elastic stop, e.g. the spring of a stop or the force of a spring, e.g. a leg spring, or the elasticity of a spring casing, which loads a locking rocker in the sole holder. The force of the support area, e.g. the elastic tongue, the leaf, the elastic additional force of the cover or the spring, is advantageously significantly smaller than the force of the release spring which loads the sole holder.・It is a thing. This ensures that the spring casing can be returned in the desired manner without any upward pivoting of the sole holder and thus without hindering release of the boot.

In the ski shown in FIGS. 1 to 4, the S-inding is constructed as a heel piece, designated as a whole by l.8 Heel piece 1 is attached to the upper side of ski-2 by a screw (not shown). It has a guide rail 3 fixed by. On top of this guide rail 3 is a heel piece l.
The bottom plate of the ski 2 is guided in displacement in the longitudinal direction of the ski 2 and can be locked in the respective desired position in a manner known per se in order to adapt the ski binding to ski boots of different lengths. . The heel piece 1 is movably guided on a guide rail 3 against the force of at least one coil spring. In this case, the coil spring rests immovably on the ski at one end in a manner known per se, and at the other end rests on the bottom plate 4 of the heel piece 1, and on top of the bottom plate is shaped like a casing. bearing block 5
is fixed.・This support block 5 has an upper range r
Extends transversely to the longitudinal direction of the ski. It has a pivot shaft 7 in the form of a pin, on which a sole holder 6 is pivotably supported. In its upper region, the sole holder 6 holds a locking rocker 9, which is likewise pivotably mounted on an axis 8 formed by a pin extending parallel to said axis. This locking rocker 9 extends substantially downward and has a locking projection 9a in its lower end region. This locking protrusion 9a is connected to a control cam fixed to the front wall of the casing-shaped support block 5, as shown in FIG. The rear end of the bearing block 5 ((is in the transverse force direction with respect to the ski length direction; The substantially U-shaped casing 12 in plan view, which is provided for pivotably supporting the abacus spring casing 2 in its side walls, has longitudinal guides 12a for the webs 13 on both side walls. have.

The flanged web 13, which extends in the longitudinal direction of the ski (on the other hand, in the transverse direction), is on the one hand constructed in the shape of an arch and has a flange-like addition in the area opposite to the area of the contour. One end of at least one release spring 15 is supported on top of which a spring plate 1 is supported.A second end of the release spring 15 is supported in a spring receiver 16. Ge1
6 is a screw 1 rotatably supported on the spring casing 12;
At 7, the release spring 15 can be adjusted in the axial direction in a manner known per se.

The locking rocker 9 forms a locking notch 9b for the web 3. 1. The web 13 is pressed into the locking notch 9b by the action of the release spring 15. Locking rocking body 9
A hollow space in the form of a notch 9c is formed next to the locking notch 9'b. By actuating the release lever 18 (/?:) in the recess 9c, the web 13 is temporarily locked in a manner that will be explained later while the sole holder is intentionally released.

A release lever 18 that grips the sole holder 6 from the side is pivotally connected to a shaft 8 disposed on the sole holder 6.A locking rocker 9 is also rotatably supported on this shaft 8. There is. A pin 19 fixed to the release lever 18 parallel to the axis 8 passes through both the side walls of the sole holder 6 and the side walls of the spring casing 12.

In this case, the pin 19 is an elongated hole 6b provided in the sole holder 6 and extending concentrically with respect to the shaft 8.
The control cam part 10, which cooperates with the locking rocker 9, passes through the substantially arc-shaped slide guide 12b provided on the tongue-shaped addition of the second tongue. The locking protrusion 9a of the movable body 9 forms a control surface 10a that is gripped when the heel piece 1 is in a sliding state. The cam section 10b moves away from the ski surface via a bend determining the cam section 10b, which has in its upper region a locking region 10C inclined towards the sole holder 6. are doing.

The sole holder 6 is acted upon by an opening spring 20 which is designed as a footed spring and loads the sole holder 6 in the release direction. This release spring 20 is located in a recess in the upper end region of the control cam part 10 and rests on the sole holder 6 on the one hand and on the bearing block 5 on the other hand.
The angle ξ for the upward pivoting of the sole holder 6 is formed by the bend 22 of the bearing block 5 . An additional part 6c fixed to the sole holder 6 comes into contact with this support block when the sole holder 6 pivots upward.

A cover 23, preferably made of plastic, is fitted over the rear end region of the spring housing 12;
It is fixedly connected to the spring housing 12, for example with rivets. The cover 23 pivots together with the spring casing 12. The cover 23 is provided with a window with a scale. This scale is provided (C) to indicate the adjusted spring force.

A plastic cover 23 which covers the splash housing 12 from above has an extension beyond the end region facing the locking rocker 9. This extension is formed by a lightly curved elastic tongue 23a several millimeters wide, the elastic tongue 23a being in the sliding state shown in FIG. 1 with the heel piece. The illustrated heel piece, located at a distance from and below the pivot axis 7 of the sole holder 6, is a Niski 8 which operates as follows.
When a vertical force is applied to the sole holder 6 from a ski boot (not shown) placed in the indexing, the sole holder 6 pivots upward 1 around the pivot 1I81II7. During this pivoting movement, the locking rocker 9 is fixed to the bearing block 2t and the control surface 10a of the control cam part 10.
K slides back and pushes the web 13 back against the force of the release spring 15 in the longitudinal guide 12a of the spring casing 12.

The locking rocker 9, which is under the action of the release spring 15 and is pivotable together with the sole holder 6, also moves the spring casing 12 to the shaft 11.
Rotate around the center. Locking protrusion 9a of locking rocking body 9
Once the release point of the control cam part 10 has been exceeded and the elastic range has been exceeded, the sole holder 6 can be swiveled into the release position with the aid of the release spring 20. In this release position, the locking protrusion 9a of the locking rocker 9 is in the locking range lo of the control cam portion 10.
Let me come into contact with c.

In this case, the release spring 15 has its web 13 resting against the end region of the longitudinal guide 12 a of the I/F spring housing 12 facing the locking rocker 9 . As a result, the ski inding is in the step-in preparation state shown in FIG. If the heel piece 1 is to be released manually, which is simply done by pushing it down into the lowered position, the release lever 18 is pivoted, for example by hand, in the direction of the arrow F1 shown in FIG. At this time, the spring casing 12 is also pivoted upward about the shaft 11 by the pin 19 moved upward within the elongated hole 6b extending concentrically with respect to the shaft 8 of the sole holder 6. It will be done. In this case, the web 13 is released from the locking notch 9b of the locking and lifting body 9 against the force of the release spring 15. After releasing the release lever 18, the collar 13 moves forward in the longitudinal guide 12a of the spring housing 12 under the action of the release spring 15 until it abuts the end regions of both longitudinal guides 12a. This course of movement is made possible by a suitable recess 9 of the locking rocker 9, which is configured and connected to the locking notch 9b.The locking rocker 9 is shown in FIG. As shown, as the sole holder 6 then moves upwardly, it passes by the locking projection 9a of the control cam portion 10, as shown in FIG. 3, under the action of the release spring 200. The control cam part 10 is pivoted away from the control cam part 10 until it can reach direction F.

Actuation of the release lever 18 and subsequent automatic upward pivoting of the sole holder 6 provides the next step of intentional release.

In the first step, release 5-18 is pulled upward. In this case, the web 13 is released from the locking rocker, and the sole holder also lifts up somewhat from the closed state.
The state shown in FIG. 2 is reached. Furthermore, as can be seen in FIG. 2, the elastic tongue 23a of the shoe ζ-230 is in contact with the pivot axis 7 of the sole holder 6. In this case, the tongue 23a is placed under some tension, as can be seen from the comparison of FIGS. The sole holder 60 reaches its highest position within both long holes 6b. In this case, the tongue 23a is fully tensioned, the sole holder 6 is swiveled further upwards, and the locking lug 9a of the locking rocker 9 is higher in the control cam part 10a, still at its maximum. Occupy a position that is not.

In the fourth stage of intentional release, the sole holder 6 is brought into a fully released position under the action of the release spring 20, as shown in FIG. During the swivel, the locking rocker 9 is in the highest position and the spring casing 12 is exposed to the elastic tongue 23a of the force ζ-23.
The web 13 is pushed downward by the force exerted by the relaxation of the locking rocker, and the web 13 is again brought into the locking rocker's 1F notch 9b. Of course, such return pivoting of the spring casing 12 occurs when the release lever 18 is released and the release lever 18 is pivoted back to the closed position about the pin 19 as shown in FIG. only. As a result,
The heel piece is ready to step in ((brought).

The arrangement of the components that cooperate with each other, for example the course of the cam section 10b of the cam part 10 (3), ensures the above-mentioned movement course. In the released position of the heel piece 1 shown in FIG. 3, the locking projection 9a of the locking rocker 9 is in contact with the locking area lOC of the control cam part 10 fixed to the bearing block.

The space obtained in this way ensures that the web 13 is not strained by the space alone, i.e. the release lever 15
The locking notch 9 of the locking rocker 9 can be opened again without operating the locking notch 9 of the locking rocker 9.
This is important for the present invention because it can reach b.

After intentional release, the heel piece is therefore ready to step in, as already mentioned, and can be closed simply by inserting the ski boot into the sole holder 6. Furthermore, it is also possible to close the sole holder 6 by hand by pushing down the sole holder 6. However, in this case larger forces need to be overcome. However, it is also possible to bring the heel piece into the closed position with very little force; for this purpose, starting from the position shown in FIG. The release lever 18 is pivoted upward until it is released from the locking notch 9a. This action takes place only against a slight force of the elastic tongue 23a, as shown in FIG. The sole holder 6 is then manually brought into the closed position, in which case only the force of the opening spring 20, which is lower than the opening spring, needs to be overcome. Web 13 by means of release lever 18 which is swung back into the closed position, for example by hand.
is again engaged with the locking groove 9a of the locking rocking body 9. During this operation, the release spring 15 is slightly compressed.

In this way the heel piece can be brought into the closed position by hand with little force. This process is chosen when it is desired to keep the heel piece closed during transport of the ski, and in order to fit the ski binding to the length of the ski boot. It's advantageous.

5 to 7, the only difference in the embodiment from FIGS. 1 to 4 is that the sole holder 106 is supported on a horizontal shaft 111 provided in the rear region of the support block 5. Unlike the example (・ru, the horizontal axis 111 is already [
1, which holds the K-spring casing 112 as described in , but due to this arrangement the pin 19 on the one hand is inserted into the slide-guided notch 1°6 of the sole holder 106.
It goes through b. This notch 106b is the release lever 1
a, c Concentric to axis 8 in the range touching B (
(extending, and the bottle 19 is the spring casing on the other hand), respectively passing through elongated holes 112b provided in each of the 12 tongue-shaped additions. The locking range 10C inclined toward the sole holder 106 becomes unnecessary.

The area of the force ζ-23 made of plastic that covers the spring casing 2 from the rear extends beyond its end area to the bottom plate 4.
or the additional part 3 facing the retaining plate 5a of the bearing block 5
It has 3. In this case, the retaining plate 5a of the support block 5 has a stopper 34 in its rearwardly extending range.

As shown in FIG. 5, the end region of the holding plate 5a can itself be constructed or act as a stone ξ. When the heel piece 1 C1l is in a sliding state, the end range of the additional part 33 of the cover 23 is connected to the retaining plate 5a.
It is located at a distance from St. ξ ξ34.

The mode of action of the heel piece l'010 illustrated corresponds to the mode of action already described in the case of unintentional release.

When opening the heel piece 101 by hand, release 7 bar 18
is pivoted upward, for example by hand, in the direction of the arrow F1 shown in FIG. The actuation of .zeta.-18 and the subsequent automatic upward pivoting of the sole holder 6 result in the following schematic release step in this embodiment. Two of these intentional release steps are illustrated in FIGS. 6 and 7.

In the first step, the tb is released and pulled upwards.
%. The web 13) is now released from the locking notch 9b of the locking rocker 9, and the locking protrusion 9a of the locking rocker 9 moves away from the control surface l○a of the control cam portion 1o without resistance. 1. When the user completes this operation, the user 2 releases the release lever and releases it. 2t. Said position of the release lever is shown in the seventh section IiC. In FIG. 7, the entire heel pin is in a state that will be described later. In the sixth section, the release lever 18 is still held by the user, but the locking rocker 9 releases the sole holder 106. , a deliberate release phase is shown in which the sole holder 106 can pivot upwardly from the closed position under the force of the release spring 20. In this case, the sole holder 106 carries the locking rocker 9 upwards with the shaft 8. Locking rocking body 9
itself is connected to the spring casing 11 by means of the abutting web 13
Rotate the two together. FIG. 6 shows an intermediate state before the sole holder 106 reaches its highest position. However, in this case, since the protruding portion 33 of the cover 23 is in contact with the stop ξ34 of the retaining plate 5a, the splash casing 112 cannot be rotated any further.

Under the action of the release spring 20, the sole holder 106 pivots further upwards and carries the locking rocker 9 upwards as well.

In the next release phase, not specifically shown, pin 1
9) The q casing 1120 reaches the end position in both elongated holes 112b. In this case, the sole holder 106 and the locking rocker 9 occupy the highest position. The spacing existing or occurring between the web 13 and the cam section 10b of the control cam part l○ in this case ensures an unimpeded and easy sliding of the locking rocker, resulting in a deliberate release. The fourth stage is shown in FIG. In this fourth stage, the locking rocker 9 has been brought, by its own weight, into a state in which the web 13 is again located in the locking notch 9b of the locking rocker 9. That is, the locking rocker 9 is rotated back and supported by the web 3 and held in a suitable position for stepping in again. 1. Push down the protrusion of the sole holder with the heel of the ski boot. by Heel Piece 101
is closed as already described for unintentional release, resulting in the state shown in FIG.

In addition, as soon as the user releases the release lever 18, the release lever 18 automatically returns to the closed state by the sole holder]06. The return rotation releases both sliding guide-shaped cavities 106b and pins 19 of the sole holder l○6 and ζ-1.
8. Dimensions of components cooperating with each other, e.g. control cam part 1
The course of the cam section lQb of 0 guarantees the movement course described in this case as well. In the released state of the heel piece 101 in which the sole holder 106 is completely pivoted upward, the locking protrusion 9a of the locking rocker 9 engages the web 13 with the locking notch of the locking rocker 9. In order to re-engage 9b,
It can be moved forward in the direction of the free end of the cam section 10b of the control cam part 10 which is fixed to the bearing block. In this case the upper limit of this locking notch 9b must be overcome. The space obtained in this way allows the web 13 to reach the locking notch 9b of the locking rocker 9 only by means of this space without applying any force again, that is to say without activating the release spring 15. This is important for the present invention because it allows for

FIG. 8 shows a modified embodiment of the heel piece 201 shown in FIGS. 5 to 7. In this case, another weak spring 8a is provided on the shaft 8, which loads the locking rocker 9 in the direction of the spring casing 112. The spring 8a is supported by the sole holder 106 with one leg and directly by the locking rocker 9 with the other leg. The spring is activated by the pivoting of the locking rocker 9 when the sole holder 10G pivots upward, and by the web 13 of the spring casing 112.
It is advantageous if it is arranged such that it is tightened after being pushed forward.

As a result, the spring 8a causes the sole holder 106 to pivot further upward, thereby causing the locking rocker 9 to move around the web 131 (
It acts as if it is being pushed towards. As a result, the limiting portion of the locking notch 9b of the locking rocker 6 is forcibly overcome. Therefore, freezing of the area of the control cam part 10 causes the locking rocker 9 to become stuck here, and the engagement between the web 13 and the locking notch 9b of the locking rocker 9, which is necessary for the step-in readiness condition, to occur. This prevents the combination from occurring.

9 and 10 show a modified part of the third embodiment of the heel piece. As can be seen from FIGS. It rests on the rear end region of the retaining plate 105a of the block 105. In this case, the end region of the retaining plate 105a is designed as a sliding guide for the stopper ξ 134.The additional part 33 of the cover 23 In the state shown in the figure, it is in contact with the stop 134 and has already pushed this stop 8134 somewhat forward against the force of the spring 35.

Heel piece 301 is therefore only partially shown.
The illustrated situation substantially corresponds to that shown in FIG. 6 of the previously described embodiment, with the difference that the spring casing 112 has not reached its highest position. According to FIG. 10, the spring housing 112 has already reached its highest position. This situation substantially corresponds to the situation shown in FIG. The structure and mode of action of the heel piece 30 is the force "-23" applied part 3.
The difference is that the pivoting and support of 3 is carried out against the force of the spring 35, so that the re-engagement of the web 13 of the spring casing 112 into the locking notch 9 of the locking rocker 9 is carried out by the action of the spring 35. Except for this point, the structure and mode of operation are substantially similar to those of the first embodiment. In this case, the dimensions in this range can be carried out with a greater degree of freedom than in the embodiment with a stationary stop. The action of the spring 35 is therefore equal to the action of the spring 8a in FIG. (Half and half.

It should be noted with this embodiment that the force of the spring 35 is advantageously significantly lower than the release spring 106 of the sole, holder l○6, which spring 35 prevents the release process during intentional or unintentional release. No untoward effects are produced or the release process is disturbed.

Therefore even after intentional release the heel piece 101.20
1,301 is in the step-in preparation state as described above, and the heel piece is closed simply by pushing the ski boot into the sole holder 106. In any case, the sole holder 106 can be closed manually by pressing down on the sole holder. However, in this case relatively large forces have to be overcome. However, it is also possible to bring the heel piece 101.201.301 into the closed state with a slight force, in the same way as the heel piece l of the first embodiment. This process corresponds to the process already described.

The heel piece 1' shown in FIG. 11 substantially corresponds to the embodiment according to FIGS. 1 to 4.

In the following description, only the points having a different structure from the first embodiment will be mentioned. Shoe sole holder 6
' is constructed higher than in the first embodiment, so that between the locking rocker 9 and the upper cover of the sole holder 6' there is a release lever 18', which will be described in detail later. The slider 28 fixed to can run unhindered.

A long hole 26 is provided in each side wall of the release lever 18', and a shaft 8 for holding a locking rocker 9 supported by the sole holder 6' is passed through the long hole 2G. The elongated hole 2G extends concentrically with respect to the pivot shaft 7. When the heel piece is in the sliding position, as shown in FIG. 11, the shaft 8 is located in the upper end region of the slot 26.

The release lever 18' is connected to the sole holder 6' via both side walls.
It is supported from above by the pivot shaft 7 of. For this purpose, the respective support range of the release lever 18' is curved corresponding to the radius of the pivot axis 7, as shown in FIG. The pins 19 fixed on the release lever 18' each pass through a recess 27 formed in the lateral region of the sole holder 6'. This notch 27 replaces the elongated hole 6b of the first embodiment. The limiting edge of each notch 27 facing the axis 8 is rounded concentrically to the pivot axis 7 and the limiting edge of each notch 27 facing the pivot axis 7 is rounded concentrically to the axis 8. It has a rounded feel.

Furthermore, in this case, the elastic tongue portion 23a of the first embodiment
Instead, a plate spring 23'a is used, which is fixed to the spring gooseong 120 cover 23', for example by a bezel 23b.

A slider 28 is supported on the lower surface of the release lever 18' so as to be movable in the longitudinal direction of the release lever 18'. In order to support the slider 28 on the release lever 18', one or more guide tongues 29 are provided which hold the slider 28 on the underside of the release lever 18', as shown for example in FIG. . The slide 28 itself extends over almost the entire length of the release lever 18' and extends beyond the end region of the release lever in the direction of the sole holder 6' above the locking lift body 9. . In this case, the slide 28 passes through a recess 6/c extending in the longitudinal direction of the ski and provided in the cover above the sole holder 6'. The slider 28 has a hook-shaped gripping member 28a. This gripping element 28a is provided for gripping the shaft 8, which is supported in the sole holder 6' in a manner that will be explained later.

For this purpose, the locking rocker 9 and the control cam part l○ are shown centrally and are provided with a recess. The slider 28 is held by a spring 30 with the gripping member 28a in front of the shaft 8, as shown in FIG. Splash 3
0 is configured as a pressure spring and is arranged in a recess of the slider 28 and is supported by the support addition 18'a of the release lever 18', which projects into the slider 28 at one end and into the recess of the slider 28 at the other end. ing. Furthermore, slider 28
is provided with an operating protrusion 28b that can be grasped by hand.

This heel piece can be released intentionally either by pulling on the release lever 18' or by pushing it down. When releasing the release lever 18' by pulling it in the direction of arrow F2 in FIG.
' is a shaft 8 which acts solely as a pivot for the release lever 18'.
Supported by An unimpeded pivoting of the release lever 18' with the slider 28 is possible by means of a cutout 6/c in the sole holder 6', so that the release of the sole holder 6' can be carried out as shown in FIGS. This can be done in the format described in the embodiments up to the figures.

When the heel piece is released by pressing down on the release lever 18', for example with a ski, ski boot, ski pole, etc., the release lever 18' is pivoted downward in the direction of arrow F3 in FIG. . In this case, the release lever 18' is fixed to a bearing block and supported on the shaft 7.

This shaft 7 serves both as a pivot for the sole holder 6' and also as a pivot for the release lever 18'. The relative movement between the release lever 18' and the shaft 8, which is mounted on the sole holder 6', is made possible by the two elongated holes 26 in the release lever 18'. During the pivoting of the release lever 18', the pin 19 fixed to the release lever 18' is pivoted upwards.

In this case, this pivoting movement is made possible by the two recesses 27 in the sole holder 6'.

Via the pin 19 the spring housing 12 is also pivoted upwards about the axis 11. In this case, web 13
is released from the locking notch 9 of the locking rocker 9 against the force of the release spring 15 and then moves into the area of the notch 9c of the locking rocker 9 as already described in the first embodiment. reach After releasing the release lever 18', the sole holder 6' lifts the ski boot placed in the sole holder 6' or, with the aid of the release spring 20, pivots the pivot point 7. and rotated upward. At the same time, the locking rocker 9 pivots somewhat backwards, and the shaft 8 holding the locking rocker 9 is inserted into the elongated hole 26.
Some inside” slides in both directions. When the sole holder 6' reaches a predetermined pivot angle, the locking rocker 9, which slides backwards through the control cam part 10, grips the web 3. This web 13 slides cleanly on the locking rocker 9 and is then pivoted together with the spring housing 12 upwards about the axis 11.

The release lever 1 is released at the same time as the spring hook 12 is rotated.
The pin 19 fixed at 8' also pivots upward.

In this case, the release lever 18' is moved around the shaft 8, which forms the new pivot axis of the release lever 18', at the arrow F2 in FIG.
, that is, the direction opposite to the direction of depression. When the release lever 8' is pivoted anew, the release lever leaves the pivot axis 7. The locking rocker 9 moves beside the control cam part lO to the sole holder 6'.
It is rotated upwards with the Shoe sole holder 6
' At the last stage of the upward pivot, the spring casing 120
The leaf spring 23'a, which is fastened to the cover 23' and which has been tensioned during the above-mentioned course of movement, becomes active and pushes the pin 19 and thus the spring casing 12 downwards. The web 13 thereby again slips into the locking notch 9b of the locking rocker 9. As a result, the release lever 18' holding the pin 19 is also brought into the closed state, so that the heel piece 1' is pushed into a state in which it is ready to be pushed in.

The heel piece, now ready for step-in, is closed again by pressing down on the sole holder 6'.

However, a slider 28 is provided in order to enable the sole holder 6' to be closed by hand with little force. The slider 2δ is difficult to grasp by hand and is pulled away from the sole holder 6' against the force of the weak spring 30.

1 At this time, the hook-shaped gripping member 28a grips the shaft 8, so both elongated holes 26 become effective (d disappear).

With the slider 28 in this state, the release lever 18
' is swiveled upwards until the web 13 leaves the locking notch 9b of the locking rocker 9 again. This action takes place only against a slight force of the leaf spring 23'a. The sole holder 6' is then manually brought into the closed position. In this case only the force of the opening spring 20 needs to be overcome.

The release lever 18' is then manually swung into the closed position together with the actuated slide 28. In this case, the web 13 is again connected to the locking notch 9b of the locking rocker 9.
engaged with. Although this engagement is performed against the force of the release force, the necessary force is applied to the sole holder 6.
′ is significantly smaller than with a single closure performed via .

The release lever 18' can be provided with an elastic locking element for the slider 28, so that the slider 28 does not have to be held in a tang during the movement sequence described above. This locking member engages a corresponding locking notch in slider 28 during actuation of slider 28. The automatic engagement of the slider 28 can be achieved, for example, if the operating range of the slider 28 is configured as its own component, and this component is configured as a two-armed arm pivotally connected to the slider 28, one of which has a lever arm. has an actuation attachment and is loaded by another spring toward the underside of the release lever 1'8', the other lever arm being configured to move away from the underside of the release lever 18'. It is possible by In this case the second lever arm is the release lever 1
While pressing down the lever 8', it comes into contact with, for example, the pivot shaft 7, whereby the lever is pivoted and the lock is automatically released.

Furthermore, the locking member of the shaft 8 can also be formed by two hook-shaped gripping members of the slider 28, which grip the shaft 8 on the sides of the locking rocker 9.

The shaft 8 is arranged so that the sole holder 6' can be easily closed.
In order to lock the slider, the slider is provided with two lateral support tongues which, by actuation of the slider, bring the sides of the locking rocker under the shaft 8. It is also possible to support it from below. In this case, the steel
Due to the relationship between the support tongue and the support tongue provided in the end region of the slider, when the heel surface is in the sliding state shown in FIG. It is advantageous if the slider +d is located at the rear of 8. In this case it is necessary to move it towards the sole holder.Also, instead of the supporting tongue, the slider is located in the inactive state. It is also possible to provide a gripping member which lies behind the locking rocker 9 in the region of the shaft 8 and is movable laterally to the locking rocker 9 towards the shaft 8 of the locking rocker 9.

The heel piece 1 shown in FIG. 12 corresponds approximately to that shown in FIG. Therefore, in the following description, only the points different from the embodiment shown in FIG. 11 will be mentioned. The main difference from No. 11 is that the inner end area does not have a stone shaft, and the outer end area is bent forward at the rear as shown in Figures 5 to 10. This is the structure of the cover 23' having an additional part 33'.

Unlike the embodiment shown in FIGS. 9 and 1O, in which the resilient support of the cover 23' to the buckle 34' is formed by a spring 35, in this embodiment the spring 35 is A goto spring 35 is fixed to the additional part 33' of the cover 23' of the casing 12 by, for example, a repen) 23'C.
' is provided.

Due to this modification, during a deliberate release process, the rubber spring 35' is tightened 1 and engages the web 13 by pressing down on the pin 19, as does the leaf spring 23'a in the embodiment of FIG. into the locking notch 91) of the locking rocking body 9. The other operating processes are almost as described above.

Furthermore, in both embodiments, the bearing block is mounted pivotably in a horizontal plane on a vertical axis fixed to the sole plate, and a control cam is provided in the front end area of the sole plate, which control cam is attached to the sole holder. A so-called diagonal release can take place by cooperating with a corresponding member arranged in the . Since the necessary measures for this purpose are well known, they are omitted in the specification and drawings.

The invention is not limited to the embodiment shown, but can be implemented in various different ways. It is also possible to use the leaf spring of FIG. 1 in the embodiments of FIGS. 1 to 4, for example in place of the extension of the cover, which is configured as an elastic tongue. It is also possible to use a spring configured as an addition to the cover in the embodiment of FIG.

Furthermore, the mechanical spring on the retaining plate 5/a of the bearing block 5' can also be replaced by another elastic element, for example a comb spring. However, instead of a rubber spring in the extension of the cover, the extension or its end region itself can be provided with transverse grooves to facilitate deformation, for example in the end region, thereby causing permanent deformation of the plastic material of the cover. It can also be constructed elastically, for example without cracking or breaking. Furthermore, Figure 11 or 1
In the embodiment shown in FIG. 2, it is also conceivable to construct the locking member of the shaft of the locking rocker by means of a pivoting gear.
