Definitions

  • the invention relates to releasable ski bindings and especially to heel retainers for bindings.
  • the invention is concerned with a releasing heel retainer having a sole retaining portion and a stepping spur for a ski binding which is pivotable in the manner of a sliding crank device on a stationary ski mounted base about a front axis that extends transversely and horizontally of the longitudinal extent of the ski, as well as slidably journalled and supported at its rearward part remote from the sole retaining part, where a release operating against spring bias effects the release of the ski boot in response to an excessive load or pressure.
  • a release operating against spring bias effects the release of the ski boot in response to an excessive load or pressure.
  • the housing defines in the release position an angle with the ski surface that is not too steep. For such a steep angle encumbers the stepping down of the housing from the release position to the retaining position, and that especially when the ski assumes an inclined position along a slope.
  • the space is to be increased through which the sole retaining part and the stepping spur pass during movement from the retaining position to the release position to reach the deadpoint position between retaining and release position.
  • the path of movement of the sole retaining part and of the stepping spur from the retaining position to the release position or vice versa can be varied. It particular, it is possible by these means to change the position of the deadpoint in relation to the retaining position and the release position.
  • the heel retainer in accordance with the invention also excels with respect to its remaining structural components by very simple, and therefore robust, construction, while it is at the same time free of operational defects.
  • FIG. 1 is a longitudinal section of the device in accordance with the invention in retaining position
  • FIG. 2 illustrates the embodiment in accordance with FIG. 1 in released position
  • FIG. 3 is a partial section along line A-A in accordance with FIG. 1,
  • FIGS. 4, 5 illustrate in a side view and in a partial section a further variant of the pivotable and slidable journalling of the rearward housing portion in accordance with the invention, where the section of FIG. 5 is taken along line BB in FIG. 4,
  • FIG. 6 illustrates in a longitudinal section another embodiment of the invention in the retaining position
  • FIG. 7 shows the embodiment of FIG. 6 in released position
  • FIG. 8 is a section taken along line CC in FIG. 6.
  • the base portion 1 of the retainer is rigidly secured to the ski. If desired, it can be slidable longitudinally of the ski against the effect of a spring, which is not illustrated. It has side walls 2 and a front wall 3, the function of which will be described more in detail hereinafter.
  • the housing 4 of this heel retainer carries a sole retaining part 5 and a stepping spur 6. It is pivotable about a forward horizontal axis that extends transversely of the longitudinal extent of the ski in side walls 2.
  • a lever joint arrangement is provided which comprises a first lever 7 and a second lever 8.
  • both levers are connected with one another, while the other free end of lever 7 is linked to the housing at axis A2, and the free end of lever 8 is linked at axis A1 to the side walls 2.
  • the housing 4 is furthermore slidably journalled and supported at its rearward part remote from the sole retaining part at side walls 2 on base 1.
  • slots 12 in the side walls 2 serve for this purpose, where the housing is slidably guided in the longitudinal direction of the ski, as well as rockable about an imaginary axis of this guiding slot-disposed at any desired location horizontally and extending transversely of the longitudinal extent of the ski.
  • This displacement takes place against the effect of the pressure spring 11 that is supported at its forward end against the front wall 3 of the base part and at its rearward end in a sleeve 13 which constitutes a structural component of the pivot able and simultaneously longitudinally displaceable bearing of the rearward part of the housing, respectively the base portion.
  • this bearing can be so constructed that the sleeve 13 is screwed with thread portion 14 into the inner thread of a rotary displacement part 15 and is adjustable relative thereto in longitudinal direction by turning.
  • the rotary displacement part 15 has lateral projections, pins, bolts or the like 16, that are slidably guided in the slots 12 of the base as well as movably joumalled in bores 17 of the housing 4.
  • the rotary displacement portion identified at 15 has lateral ridges 18 which are slidably fitted into the slots 12 of the side walls 2. Rivets 19 are provided on these ridges that pass through bores 20 in the housing 4, where they are rotatably journalled.
  • the ridges 18 protect the rotatable displacement part against turning within the slots 12, which in that event must be longer than in the embodiment of FIG. 3 to correspond in this case to the length of the ridges 18.
  • the levers 7 ,8 are in such a position that they assume either the retaining position (FIG. 1) or, upon passing through the deadpoint, the released position, under the effect of the pressure spring or of several pressure springs. This will be explained more in detail hereinafter with reference to the embodiment of FIGS. 1 and 2.
  • spring 11 presses the housing to the position illustrated by way of sleeve 13, housing 4, linkage position A2, levers 7,8 and the linkage point A1, while a downwardly directed force is exerted against the forward part of the housing.
  • the longitudinal axis L1 of the first lever relative to the surface of the ski which here corresponds to the bottom surface 1 of the base portion, defines a smaller angle than the longitudinal axis L2 of the second lever.
  • the angles that are defined by these two levers with the surface of the ski open rearwardly.
  • first lever 7 is longer than the second lever 8, and its longitudinal axis L1 is disposed below the linkage location A1 of the sec- 0nd lever and at the side walls 2.
  • the studs 16 or the ridges 18 are disposed in the center area of the slots 12.
  • the first lever 7 pivots upwardly about the pivot point 9 in counterclockwise direction until the angle a defined by the longitudinal axes L1, L2 has become zero. With this the deadpoint position already explained is reached. It thereby pulls the housing somewhat upwardly, while it rocks upwardly simultaneously across the linkage point A2 in the longitudinal direction of the ski against the force of the spring 11 until the explained deadpoint position has been reached. During this movement the linkage point 9 rests on a counterbearing which in this embodiment is defined by the upper end surface of the forward end wall 3.
  • the shorter lever 8 effects an arcuate movement in clockwise direction about the linkage axis or location A1, and the housing together with the sole retaining part and the stepping spur is pulled backward by the force of spring 11.
  • the height elasticity of the binding i.e., the stretch which the sole retaining part and the stepping spur pass through from the retaining position until reaching the deadpoint position, is greater than in known heel retainers, for example 1020 mm, and in given cases still more.
  • the linkage point A2 passes through the area of angle a, the sole retaining part is not yet pulled back, but as explained above, it is pressed forwardly and thus keeps the boot firmly in any position of this section of movement.
  • the step ping spur 6 is employed.
  • a catch is provided on the inside of the housing, for example a shoulder 21, which is so arranged that as the housing is stepped on, it moves to the operating engagement against levers 7 ,8, preferably at their common connecting link 9.
  • a further advantage of this arrangement resides in that the spring always remains in the same position in the lower area of the retainer. Thus, it is not moved up and down as the housing is rocked at its forward end, and thus it is not bent.
  • a hand release may be provided, which preferably acts against the lever 8.
  • an extension of this lever can itself serve as the hand release, so that by pressing down this extension (not shown), the linkage point 9 is moved out of the position of FIG. 1, upwardly into the release position of FIG. 2.
  • FIGS. 6-8 A further possibility for the hand release is illustrated in FIGS. 6-8.
  • the structural elements 116 shown there correspond exactly to the same structural elements of FIGS. 1 and 2.
  • a hand release lever 22 is provided which by means of the joint 9 is pivotally connected with the two levers 7,8.
  • a hand release lever 22 is provided which by means of the joint 9 is pivotally connected with the two levers 7,8.
  • lever 22 is supported against the linkage point A1 or it engages the point 23 of lever 8 which is above it.
  • the linkage point 9 is rocked clockwise about the linkage point Al until the deadpoint is passed and the spring 11 further moves the retainer or its parts into the release position in accordance with FIG. 7.
  • the moving of the binding out of the release position into the retaining position of FIG. 6 is effected also here by pressing down the stepping spur 6.
  • the section C-C in accordance with FIG. 8 shows in detail the construction and connecting of levers 7,8 of the linkage points or pivots A1, A2 and 9, as well as of the release lever 22, which are here in the form of pins or bolts.
  • the levers 7,8 may comprise a pair of levers.
  • the upwardly extending lugs 2 of the side walls 2 carry the linkage pin A1.
  • a part of the ski is identified by S.
