Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a shoe sole holding member that is swingable around a horizontal transverse axis and is provided with four closing barrels, and a shoe sole holding member that is swingable in parallel with the axis of the shoe sole holding member. a stop member movable in the longitudinal direction of the ski and actuated by a release lever; 1-1 the stop member is movably supported in the sole holding member and is swingable together with the sole holding member; The element engages the base member and the sole retaining member [is provided with a handle for arbitrarily opening the heel piece, the handle being operated against the action of a retaining spring. , relates to a heel piece of a ski safety buckle, adapted to allow the blocking element to move into a released position in the operated state.

Various types of this type of heel piece heel retention device are known, and compared to other known heel pieces, there is no need to tighten the release spring, so the ski boot is released with little force. It has the advantage of being able to be released based on the desire to do so. Small structures that are theoretically possible have not hitherto been realized. Manufacturing costs are high;
Due to the large volume and weight, it is not possible to obtain a heel piece that meets the demand.

SUMMARY OF THE INVENTION The object of the present invention is to provide a heel piece for the M-type ski safety binding described at the beginning of this section, which is small, lightweight, and can be opened freely.

This object is achieved according to the invention by forming the main body element as a connecting rod which, together with the member engaging the stop element and the sole retaining element, is pivotably connected to the rank and has a handle. This is accomplished by forming a protrusion that normally prevents relative movement between the connecting rod and the crank. Unlike conventional construction, the member engaging the stop member is not anchored by the blocking element. Therefore, no relative movement takes place between the stop member and the main body element in order to fully release it.

The trochanter, which is supported by the lever and is spring-loaded against the stop, is preferably provided with a member that engages the stop, thereby reducing wear on the second bearing.

It is desirable to provide a crank pin which connects the connecting rod to the crank and cooperates with the protruding portion of the handle.

According to a preferred embodiment of the present invention, the sole support member of the crank is supported on the seat. As a result, the number of parts is reduced, the dimensions are also reduced, and the weight of the heel piece is reduced.

Further advantageous embodiments of the invention are described in the respective implementation sections.

Next, preferred embodiments of the present invention shown in the drawings will be described in more detail.

On the ski 1, a generally U-shaped housing member 3 is disposed movably in a carriage-like manner in the longitudinal direction of the ski 1 above a guide member 2 which is screwed onto the ski 1. The housing part 3 consists of transverse walls 4 connected to each other by transverse members 5 perpendicular to the longitudinal direction of the ski 1. A set screw 6 is rotatably moored to the screw hole of the horizontal member 5, and the set screw 6 is attached to a slit in the substrate forming the guide member 2, which forms an opposing screw and extends parallel to each other. They are engaged by threads 7 having a substantially square cross section. The front surface of the set screw 6 forms a bell spring-shaped anchoring part for the pressure spring 8, and the other end of the pressure spring 8 is supported by a stop part of the housing member 3 formed by the horizontal yoke 9K. has been done.

A pivot bolt 10, II is fixed to a side plate-shaped portion extending upwardly of the horizontal wall portion 4 of the housing member 3, and a short lever 1 forming a crank is attached to the pivot bolt 10, II.
2 and a stop lever 13 are respectively supported. The stop lever 13 has a foundation cam portion 15 extending obliquely at a corner portion 141 at its lower end. The forked stop lever 13 is
A closure spring 18 is supported on the shaft 16 via a molded body 17, and the other end of the closure spring 18 is supported on a set screw 9 and screw 19
are screwed to the transverse member 5 of the housing member 3.

It is equipped with 13 stop levers and a pin 20 that limits the rotation angle of the stop lever 13.

A sole holding member 2 is attached to a pivot 10 that is integral with the housing.
1 is also swingably supported, and a sole image holding member 21,
A heel pressing member 22 and a closing door 23 are provided at the front end. The sole holding member 21 is formed as a housing as a whole and substantially covers the housing member 3 which is fixedly attached to the ski 11 and held on the guiding member 2.

The sole holder 21 has a pivot 24 near the closing pedal 23, and a short lever 25 is swingably supported on the L1 pivot 24. The connecting rod 27 is pivotally connected to the other end of the lever 25 via a pivot bolt 26, and a crank pin 28 is attached to the swinging end of the lever 2.
It is pivotally connected via.

The open window 4 of the sole holding member 21 (is the release lever 3
0 is swingably supported around a pivot lever 29. The release lever 30a has a bent leg 11!31 at the rear end, and the leg 31 has a protrusion 32 at the lower end, and the protrusion 32 holds the sole holding member 210 in the rest position of the release lever 30. The coil portion of the torsion spring 34 is pushed into the top of the pivot bolt 2, and the leg portions 35 and 36 of the spring 34 are supported on the sole holding member 21. and the release lever 30.The release lever 30
The lower surface number C has a snout-shaped protruding portion 37, and the protruding portion 37 forms a substantially acute-angled lever arm with respect to the release lever 30. The protruding portion 37 has an abutment 38 on its front end surface, and the crank pin 28 abuts on the abutment 38 when the release lever 10 is in the starting position. However, when the locking release lever 30 is pushed down, the crank pin 28 moves to the abutment surface 3.
8 into the forked recess 8Ilse between the release lever 30 and the protruding portion 37. In this position shown in FIG. 2, the stop formed by the pivot gel connecting the lever 25 to the connecting rod 27 is almost powerless to move beyond the upper heel of the cam part 15, thus retaining the sole. The member 21 can be swung into its open position.

For swinging the sole holding member 21 to the open position, a second spring is disposed on the pivot point 10, and its leg-shaped portion 40
．． 41 is in contact with the sole holding member 21 and the pivot gel 11, respectively.

1. In order to enable the crank pin 28 to return to the base position on the abutment surface 38 after the release lever 30 is operated, a torsion spring 42 is disposed on the pivot gel 24, and the legs of the torsion spring 42 The shaped portions 43 and 44 abut on the sole holding member 21 and the pivot port 26, respectively.

A sleeve or trochanter is supported on the pivot 26 and forms a cam that slides on the cam member 15.

Since the lever 12 and the connecting rod 27 have an acute angle, a very slight force is required to release the heel push-up member from the release lever 3.
Just add it above 0.
