Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a rail fixing clip for fixing a rail onto a support such as a sleeper member or a base, and more specifically,
This invention relates to a rail fixing clip for fixing and removing a rail from a support with a simple one-touch operation.

[Prior Art and Problems to be Solved by the Invention] Various types of fixing fittings have been used for fixing rails to supports (sleeper members, bases, etc.). Rail nails driven into wooden sleepers may come off due to loosening, requiring a great deal of effort to drive or remove them.
It has the disadvantage that it cannot be applied to metal sleeper members such as shapes.

Also, bolts/nuts or bolts/bolts can be used as fixing fittings.
A method of tightening and fixing the rail and support using nuts and washers is also used, but the bolt or nut is rotated many times with a tool such as a wrench each time the rail is fixed or removed. This has the disadvantage that it takes time to fix and remove the rail.

On the other hand, Japanese Unexamined Patent Publication No. 18761/1989 discloses a rail fixing structure using a substantially U-shaped rail fixing clip. This rail fixing structure has a single-shaped stud protruding from the sleeper member located on the side of the flange of the rail, and a space between the lower surface of the head of the single-shaped stud and the upper surface of the flange of the rail. The rail is configured to be fixed by inserting a substantially U-shaped clip member into the rail with strong force. The rail fixing clip itself can be attached with a single touch.However, in the rail fixing structure with this configuration, in addition to the rail fixing clip, it is necessary to protrude a single-shaped stud on the support, which reduces the number of parts. The disadvantage is that there are many Also, as shown in the above publication,
A disadvantage is that a special tool that uses the lever principle is required to insert and remove the rail fixing clip.

Therefore, an object of the present invention is to have a simple structure, and
To provide a rail fixing clip capable of fixing and removing a rail to a support body with a simple one-touch operation.

[Means to solve the problem]

In order to achieve the above object, the present invention has the following configuration. That is, it is a bent rod-shaped rail fixing clip for fixing a rail having a flange portion whose upper surface is inclined downward toward the side of the rail body on the rail support surface of the support body, and the clip is in the vicinity of the above-mentioned 7 run portions. A rod-shaped roughly fitting portion that can be inserted into and engaged with a hole formed through the support body, and the roughly fitting portion is formed separately, and when the roughly fitting portion is engaged with the hole of the support body, A lower pressing part is provided on the roughly joining part so as to be located on the back side of the body, and a lower pressing part is provided on the roughly joining part so that it is located on the rail supporting surface side of the support when the roughly joining part is engaged with the hole in the support. By rotating along the top surface of the 7-run section from the outside of the flange section of the rail about the joining section, the flange section and support body are moved up and down in cooperation with the lower presser section. Tightening is done in the direction of the clamping bar-shaped upper holding part and the rail fixing position that is formed integrally with the upper holding part and that the tip of the upper holding part crosses a perpendicular line drawn from the center of the join to the side of the rail body. and a stopper portion that comes into contact with the side surface of the rail body on the near side of the perpendicular line when the rail body is rotated up to the vertical line.

[Action and effect of the invention]

When fixing a rail to a support using the rail fixing clip having the above configuration, first, the upper presser and lower presser are respectively attached to the support by engaging the roughly joined portions into the holes formed in the support. on the rail support surface side and on the back side of the rail support surface. Next, by rotating the upper presser part from the outside of the flange part of the rail toward the rail body along the 7th rung part, centering on the roughly joined part engaged with the hole, the upper presser part is moved between the upper and lower insert parts. Insert the rail flange and support body. At this time, the upper surface of the 7-run section of the rail is tilted downward in the direction away from the rail body, so as the vertical insertion section is rotated toward the rail body, the wedge effect of the flange allows the vertical insertion The parts are expanded elastically. Due to the elastic restoring force of the clip that is generated along with this expansion, the 7 langes and the support body are clamped in the vertical direction.

The top surface of the seven flange portions of the rail has a maximum inclination angle in a cross section perpendicular to the longitudinal direction of the rail. Therefore, a perpendicular line (hereinafter referred to as
When the tip of the upper presser foot is on this reference line, the clamping width between the upper and lower inserts is at its maximum.
When the distal end side of the upper holding part is further rotated beyond the reference line, the clamping width between the upper and lower inserting parts becomes smaller than the above-mentioned maximum width. Therefore, when the tip of the upper presser part exceeds the reference line, the spring force of the clip causes the upper presser part to rotate in a direction that further narrows the clamping width between the upper and lower insertion parts, and the upper presser part attempts to rotate in the return direction. will be suppressed.

On the other hand, the stopper part that is formed integrally with the upper presser part is
When the tip end of the upper presser is rotated to the rail fixing position beyond the reference line by a predetermined amount, it comes into contact with the side of the rail body on the near side of the reference line, thereby preventing further rotation of the upper presser. do.

Therefore, when the upper and lower insertion parts are rotated to the rail fixing position where the stopper part comes into contact with the side surface of the rail body, the rail stopper clip is in a stable position, and no special external force is applied to rotate the rail stopper clip. Unless added, the rail retaining clip will not rotate. When the rail fixing clip is in a stable position (rail fixed position), the force in the lateral direction of the rail that acts on the clip from the rail is not received by the inner surface of the hole in the support body through the hole image joint of the clip. As a result, lateral vibration of the rail can be reliably prevented.

Note that the rail fixing clips may be installed on both sides of the rail, but an inverted-shaped fixing bracket should be provided protruding from the support on one side of the rail, and the rail fixing clip should be attached to the other side of the rail. You can do it like this.

The rail fixing clip can be easily rotated in a one-touch manner to the above-mentioned stable position by hitting it with an appropriate force using a general-purpose tool such as a hammer. Also, when releasing the fixation of the rail with the rail fixing clip,
Similarly, by hitting in the opposite direction with a hammer or the like, the rail fixing clip can be easily rotated to the rail release position in a one-touch manner.

The rail fixing clip of the present invention having the above configuration has a simple structure consisting of a hole image matching part and an upper and lower inserting part, so it can be manufactured at low cost. Further, in order to use the rail fixing clip, it is sufficient to form a hole in the support body, and no other special fixing parts are required, so that an inexpensive rail fixing structure can be realized as a whole.

Therefore, according to the present invention, the structure is simple, and furthermore,
It is possible to provide a rail fixing clip that allows a rail to be fixed to and removed from a support with a simple one-touch operation.

Further, in the rail fixing clip according to the present invention, the hole image matching part and the upper presser part can be formed continuously and integrally by bending a rod-shaped body, so that it can be easily manufactured. On the other hand, since the lower presser part is formed separately from the hole image matching part, the lower presser part can be fixed to the hole image matching part after the hole image matching part is inserted into the hole of the support. in this case,
Insertion of the hole image matching portion into the hole of the support becomes extremely easy, there is no restriction on the position of the hole formed in the support, and there is no need to make the hole into a special shape.

When the lower presser part is formed separately from the hole image joint part, the lower presser part can be fixed to the hole image joint part by, for example, welding after the hole image joint part is inserted into the hole of the support body. A threaded groove may be formed on the outer periphery of the hole image matching portion, and a threaded hole that is screwed into the threaded groove of the hole image matching portion may be formed in at least one member constituting the lower presser portion. With such a structure, the rail fixing clip can be attached to and detached from the support body, making it possible to reuse it.

Even if the lower presser part is formed separately from the hole image joint part, once the lower presser part is fixed to the hole image joint part, the rail can be fixed and released with the one-touch operation described above. I can do it.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

1 and 2 show a first embodiment of the present invention. Referring to these figures, a rail l on which a trolley or the like runs, for example, has a rail main body 2 having a head portion 2a and a flange portion 3 integrally formed at its lower end, and the upper surface of the flange portion 3 is connected to the rail. It has a tapered surface that slopes downward toward the sides. Further, in this embodiment, H-shaped steel is used as the support body 5 that supports the rail l.

As can be seen in FIG. 1, the support 5 extends in a direction transverse to the rail I. Although not shown in the drawings, a pair of rails are laid in parallel on respective supports disposed at predetermined intervals along the length of the rails.

As shown in FIG. 1, holes 6 and 7 are formed in the rail support surface of the support body 5 so as to be located on both sides of the flange portion 3 of the rail l and penetrate in the vertical direction. These holes 6
, 7 each have a rail fastening clip lO according to the present invention.
can be installed.

The rail fixing clip 10 in this embodiment has a rod-shaped hole image fitting portion 11 that can be inserted into and engaged with the hole 6 or 7 of the support body 5, and the hole image fitting portion 11 extends substantially linearly. At the upper end of this hole image matching part 11, a rod-shaped upper presser part 12 is also continuously formed, and this L presser part 12 is connected to the second L presser part 12.
As shown by the medium phantom line, it is bent at a substantially right angle from the upper end of the hole image matching portion 11 .

A stopper portion 14, which will be described later, is bent at the tip of the upper presser portion 12.

On the other hand, the lower presser portion generally indicated by the reference numeral 13 has a hole image matching portion 11.
It is formed separately from the

The lower holding part 13 consists of two nut members 20.21, and these nut members 20.21 can be screwed into a threaded groove 11a formed on the outer periphery of the hole image matching part 11.

Since the hole image matching portion 11 extends straight, it can be inserted into the hole 6 (or 7) of the support body 5 very easily. Furthermore, there are no restrictions on the position, shape, etc. of the hole 6. On the other hand, the nut member 20.2 as the lower pressing part 13
1, after inserting the hole image fitting part 11 into the hole 6, the hole image fitting part 11 is inserted.
is screwed into the screw/1lla and fixed in place.

The upper and lower insertion parts 12, 13 of the rail fixing clip attached to the support 5 in the above-described manner are horizontally pivotable about the hole image fitting part 11 engaged in the hole 6. When these upper and lower insertion parts 12.13 are rotated from the outside of the flange g3 of the rail 1 toward the rail body 2 side, the flange part 3 of the rail l and the support 5 are located between the upper and lower insertion parts 12.13.
is inserted in a wedge shape, and due to the wedge effect of the flange portion 3, the upper presser portion 12 is inserted as shown by the second solid line.
It expands elastically upward. At this time, due to the elastic return force generated in the clip IO, the flange portion 3 and the support body 5 are clamped in the vertical direction by the upper and lower insertion portions 12 and 13.

In order to prevent the clip 10 from being damaged when the upper holding part 12 is expanded and to obtain a large clamping force by the upper and lower holding parts 12.13, the upper holding part 12 and the hole image matching part 11 of the clip IO are Although it is preferably made of a metal bar with high springiness and mechanical strength, such as spring steel, it may be made of any other material that meets these requirements.

As described above, since the upper surface of the flange portion 3 of the rail 1 is a tapered surface, the upper surface of the flange portion 3 has the maximum inclination angle in a cross section perpendicular to the length direction of the rail l. Therefore, when the upper presser part 12 rotates clockwise in FIG.
Until the tip side reaches the perpendicular line (reference line) Although the amount of opening increases, if the distal end side of the upper presser part 12 further rotates beyond the reference line X, the amount of expansion of the upper presser part 12 decreases with the rotation. Therefore, as shown in FIG. 1, when the distal end side of the upper presser part 12 is rotated to a position exceeding the reference line X, the spring force of the clip lO causes the
The upper presser part 12 attempts to further rotate in the direction in which the clamping width between the upper and lower pressers 12 and 13 narrows, that is, in the clockwise direction, and rotation in the opposite direction (counterclockwise) is inhibited.

On the other hand, the stopper part 14 bent at the tip of the upper presser part 12 rotates to the rail fixing position where the tip side of the upper presser part 12 exceeds the reference line X by a predetermined amount, as shown in FIG. It is formed so as to come into contact with the side surface of the rail main body 2 on the near side of the reference line X when the rail body 2 is moved. That is, the distance (rotation radius) from the center of the hole image matching portion 11 to the contact point P of the stopper portion 14 is set to be longer than the distance from the hole image matching portion 11 to the side surface of the rail body 2. .

Therefore, the stopper portion 14 comes into contact with the side surface of the rail body 2, thereby preventing further rotation of the upper presser portion 12 in the clockwise direction.

Therefore, when the upper and lower holding parts 12.13 are rotated to the rail fixing position where the stopper part 14 comes into contact with the side surface of the rail body 2, the clip 10 is in a stable position, and a special The clip IO will not rotate in either direction unless an external force is applied. When the clip IO is in such a stable position, the force in the lateral vibration direction of the rail l that acts on the upper holding part 12 or the stopper part 14 of the clip IO from the side surface of the rail body 2 is caused by the hole image alignment of the clip 10. Since the receiver is to be fastened on the inner surface of the hole 6 of the support 5 via the part 11, at least two rail fastening clips should be arranged in the above-described manner using the holes 6.7 on both sides of the rail l. As a result, it is possible to reliably prevent the rail l from wobbling laterally.

In addition, in the illustrated example, as can be seen from Fig. 2,
A slight gap is created between the tip of the flange portion 3 of the rail l and the hole image matching portion 11 of the clip 10. Even if such a gap exists, as described above, the upper holding part 12 or the stopper part 14 of the clip 10 will come into contact with the side surface of the rail body 2, and the hole image matching part 11 of the clip 10 will not fit into the hole 6.
(or 7), it is possible to prevent the rail l from lateral wobbling, but the material of the clip lO,
Depending on the rod diameter, etc., if there is a slight gap between the tip of the flange portion 3 of the rail l and the hole image matching portion 11 of the clip IO, the lateral force from the rail 1 may cause the clip lO to This causes the upper holding part 12 to undergo elastic or plastic bending deformation, which in turn causes play in the rail l and the clip lO to easily come off.

Therefore, although not shown in the drawings, the holes 6.
It is preferable to position 7. With this configuration, the flange portion 3 of the rail l directly applies force to the inner surface on the opposite side of the hole 6.7 via the hole image matching portion 11 of the clip 10, so that the lateral direction from the rail 1 The risk of bending deformation of the upper holding part 12 or the stopper part 14 of the clip IO due to force is greatly reduced.

The rail fixing clip 10 can be easily rotated in a one-touch manner to the rail fixing position by hitting it with an appropriate force using a general-purpose tool such as a hammer. Further, when releasing the fixation of the rail l by the rail fixing clip 10, the rail l can be easily rotated in a one-touch manner to the rail release position by hitting the rail l in the opposite direction with a hammer or the like.

As described above, when rotating the clip 10 to a stable rail fixing position, it is necessary to expand and deform the upper and lower holding parts 12, 13, so a required rotation torque is required. Therefore, in order to obtain the required rotational torque while reducing labor, it is desirable to hit the clip 10 at a position as far away from the rotational center as possible with a hammer or the like. Therefore, for this purpose, in the illustrated embodiment, an extension end 15 is further bent at the tip of the stopper part 14. As can be seen from FIG. 1, this extended end portion 15 is formed to protrude to the side of the head portion 2a of the rail body 2 when the clip 10 is in the rail fixing position. Therefore, the extension end 15 located far away from the center of rotation of the clip 10 can be hit with a hammer or the like without being obstructed by the head portion 2a of the rail l, so that the required rotation can be achieved while reducing labor. torque can be obtained.

In the rail fixing clip IO having the above configuration,
The hole image joining part 11, the upper presser part 12, the stopper part 14, and its extended end part 15 are continuous and integral, and can be easily manufactured by bending and threading a rod-shaped body. On the other hand, a nut member 20 configuring the lower presser portion 13 .
For 21, a commercially available product can be used. therefore,
A rail fixing clip can be manufactured at low cost.

Furthermore, in order to use the above-mentioned rail fixing clip 10, it is only necessary to form holes 6 and 7 of a simple shape into which the hole image fitting portions 11 fit at appropriate positions on the support body 5 (or other special Since no fixing parts are required, it is possible to realize an inexpensive rail fixing structure as a whole.

In the first embodiment, the two nut members 20 and 21 are used as the lower presser part 13, so that the nut members are not easily loosened, but it is possible to use only one nut member as the lower presser part 13. It's okay.

3 and 4 are diagrams similar to FIG. 2 showing a second and third embodiment of the present invention, respectively. In these figures, in order to avoid complication of explanation, the same reference numerals are given to the same components as in the first embodiment, and detailed explanation thereof will be omitted.

It consists of a washer member 22 having an insertion hole therethrough.

In the third embodiment shown in FIG.
After being inserted into the hole 6, a lower presser portion 13, which is formed separately from the hole image matching portion 11, is fixed to the hole image matching portion 11 by welding 24 or the like.

Although the illustrated embodiments have been described in detail above, the present invention is not limited only to the embodiments described above, and within the scope of the invention described in the claims, the shape of each component and the connection form etc., changes can be made.

For example, the nut member 20 and the washer member 22 in the first embodiment and the second embodiment, and the lower presser part 1 in the third embodiment.
