Description

[Detailed Description of the Invention] The present invention relates to a binding device used for skiing.

Conventional devices of this kind are configured such that the shoe is fixed by stepping on the heel of the ski boot into the heel support frame, and the heel of the shoe is released by externally operating a release lever. .

In such a device, for example, the
Publication No. 43266 and Utility Application No. 143111 filed in 1972
As disclosed in Japanese Patent No. 60978, in many cases, the release lever is operated by a "lever action", thereby obtaining a light release action.

In this way, in a binding device that utilizes "lever action," this design increases the distance between the leverage point and the fulcrum to make the release motion even easier, and utilizes "lever action" when stepping on the shoe. The purpose is to make it possible.

The proposed device will be explained below with reference to the attached drawings.
In Figures 1 to 3, 1 is a base fixed to a ski, 2 is a main body case attached to the base 1, 3 is a presser housed in the main body case, and 4 is this presser. A pressing coil spring 5 urges the child forward, and a position adjustment screw 5 is provided to adjust the position of the case body 2 on the base 1.

6 is a heel receiving frame attached to the front part of the main body case 2, and 7 is a release lever attached to the rear part of the main body case 2.

The main body case 2 is configured to be movable on the base 1 by operating a position adjustment mechanism (not shown) built in the lower part with the adjustment screw 5, and this configuration is similar to that of a conventional binding device. It is.

The pusher 3 is housed in the main body case 2 so as to be movable in the front-rear direction, and is always pressed forward by the push coil spring 4. This pushing force is applied to the rear end of the push coil spring 4. A desired selection can be made by moving the provided press plate 41 using the screw 42.

A through hole 31 is provided in the presser 3 so as to be perpendicular to the moving direction, and a support shaft 3 is provided in the through hole 31.
2 is attached so that its both ends protrude to the sides of the main body case 2.

On both sides of the main body case 2, long cut windows 21 are formed in the front and back direction so that the support shaft 32 can move forward and backward together with the presser 3, and on both sides of the lower front of the case main body 2, protrusions are formed, respectively. For example, a projecting piece 22 is provided.

The heel receiving frame 6 is provided with a heel cup 61 for holding the heel of the ski boot at its front part, and a tread plate 62 that comes into contact with the bottom surface of the heel of the ski boot. is pivotally supported by the main body case 2 behind the cut window 21, and the return spring 63 is an example of the return means.
It is always urged to rotate upward and stay fixed. Furthermore, link pieces 64 are provided on both sides of the heel receiving frame 6, and each of the link pieces 64 has one link piece.
One end is pivotally attached 65 to the heel receiving frame 6, and the other end is provided with an axially long elongated hole 641, into which the support shaft 32 is fitted.

The heel receiving frame 6 rotates in front of the pusher about the pivot 23 as a fulcrum, and presses the pusher 3 while crossing the extension line l of the axis of the push coil spring 4, as shown in FIG. It has a rotation locus a that causes the coil spring 4 to retreat against the coil spring 4, and rotates upward or downward from the state in which the pivot 23, the support shaft 32, and the pivot point 65 of the link piece are located on a straight line. At this time, the pusher 3 presses forward through the link piece 64.

The release lever 7 has an operating portion 71 extending rearward, and both front ends thereof are pivotally attached to both sides of the support shaft 32 of the presser 3, and a long hole 72 is formed in the body.
The pivot shaft 23 is fitted into the elongated hole 72.

Also, this release lever 7 has its front lower edge 73
is in contact with the rear surface of the projecting piece 22 of the main body case 2.

Therefore, the release lever 7 is always connected to the pusher 3 via the support shaft 32, and the forward pressing force of the pusher 3 fixes the operating portion 71 in an upwardly rotating position. When pressed downward, it rotates by the angle regulated by the elongated hole 72 using the protruding piece 22 as a fulcrum, and at the time of this rotation, the support shaft 32 is moved rearward, thereby simultaneously pushing the presser 3 into the pressing coil spring. 4 and moves backwards.

Since the proposed device is as described above, normally the heel receiving frame 6 is in the position of the return spring 63 as shown in Fig. 4A.
The release lever 7 is also rotated and fixed upward by the force of the pressing coil spring 4, as shown in FIG. 5A.

Now, when the heel receiving frame 6 is rotated downward while stepping on it with the heel of the shoe, the heel receiving frame 6 first pushes the presser 3 against the force of the pressing coil spring 4, as shown in FIG. 4B. It is moved back in the direction of the arrow and then fixed in the lower position as shown in FIG. 4C.

In this state, the force of the pressing coil spring 4 is applied to the heel receiving frame 6 via the pressing member 3, so that the heel receiving frame 6 holds the heel of the ski boot with a predetermined force.

In order to release the binding device of the present invention in such a state, the operating portion 71 of the release lever 7 may be pressed with a stock or the like, and by lowering the operating portion 71, as shown in FIG. 5B, As the presser 3 moves in the direction of the arrow, the support shaft 32 moves backward in the elongated hole 641 as shown in FIG. 63 to return to rotation, and after rising slightly, the heel of the ski boot is urged in the upward direction by the pressing coil spring 4, so that the heel of the ski boot can easily escape from the heel cup 61. I can do it.

The proposed device has a heel receiving frame 6 and a release lever 7 like this.
Since these are connected to the same support shaft 32, the combination structure of the pusher 3, heel support frame 6, and release lever 7 can be made extremely simple. This is a lever action that applies force to the support shaft 32 as a fulcrum, and the rotational action when releasing the release lever 7 is also a lever action that applies force to the pivot shaft 23 using the protrusion 22 as a fulcrum, so the pressing coil has a strong force. Even if the spring 4 is used, there is an advantage that the pusher 3 can be easily retreated with a small force, and furthermore, the fulcrum for the lever action is provided below the front of the main body case 2. Another effect is that by increasing the distance between the fulcrum 22 and the point of force 71, a good leverage effect can be obtained.
