Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a safety key binding,
In particular, the heel piece has a sole holder that is pivotable about a transverse axis supported on a bearing block that can be fixed to the sole plate, which loads the sole holder into the release position. It is held in a sliding state by a locking rocker which is under the action of a release spring and which is pivotably supported on the sole holder, with the locking rocker being on one side. It has a locking projection which is slidably engaged under a control cam part arranged on the bearing block and has a locking notch on the other side, in which at least one A web loaded by one spring is adapted to be engaged at least in a sliding manner, the web being supported in a pivotable spring casing in a bearing block and constrained relative to the spring casing. A release lever is provided which is movable and is supported on the sole holder for intentional release of the sole holder, the release lever having a pin connecting the release lever with the spring casing. Regarding the format of

Such ski bindings, especially heel pieces, have been commercially available and have been highly valued for several years. In such heel pieces, the sole holder and the spring casing are mounted pivotably about a common axis in the rear region of the bearing block. When the sole holder is intentionally released by pulling the release lever, the web is released from the locking notch of the locking rocker, thereby fixing the locking rocker to the bearing block. The sole holder is now free to pivot upwardly about its pivot axis. However, in this case the heel piece is not ready to step in after the sole holder has been intentionally released. Additional operations are required to re-insert the boot or to close the sole holder. For example, first the release lever is closed by applying force and the web is re-engaged in the locking notch of the locking rocker;
The sole holder is then closed by being pushed down. However, it is also possible first to close the sole holder, for example by inserting a ski 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 is pivotable on an axis remote from the pivot axis of the spring casing, which is arranged in the upper region of the bearing block. Supported. 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 rocker is constructed in sections over almost its entirety, and a pawl is arranged between the two parts of the locking rocker. This pawl is supported on a shaft provided for rotatably supporting the locking rocker. 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. To release the sole holder, the actuating appendage of the pawl is pressed down against the weak spring force, the web is released and the spring casing is swiveled upwards with the aid of the leg 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 the ski binding is brought into a ready-to-step-in state. 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 arrangement 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 which is supported in the lower rear region of the bearing block. In this arrangement, the release lever and the spring casing are connected via a pin, so that intentional release is effected by pivoting the release lever upwards. In this design, easy intentional release is achieved 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 ski bindings of this construction are They are relatively expensive and prone to failure. In addition, in order to change the relative position, either the locking rocker must be adjustable transversely to the longitudinal axis of the ski binding, or the spring housing must be adjustable in the direction of its pivot axis. This construction also results in high construction costs, so ski bindings of this construction have not been fully evaluated to date.

1 to 4 of Swiss Patent No. 500,730 discloses an arrangement in which the release spring is arranged in a release lever, which is constructed as a U-shaped component in plan view. . In this case, the release lever and the spring housing are essentially one and the same component and are mounted pivotably about a common transverse axis, which is mounted on a bearing block. Since the locking rocker is likewise mounted on the bearing block, it can only perform a pivoting movement during the release process and cannot move upwards. The sole holder itself is pivotable about another transverse axis, which is also supported on a bearing block.

Due to the above-mentioned design, the release spring must be tightened to the same degree during an intentional release process as during an unintentional release process. The locking rocker is therefore always under the action of the release lever, so that the sole holder is spring-loaded throughout during the step-out. This known structure therefore does not allow easy step-out.

In the known construction, a tension spring is used as the return spring. When the release lever, which also functions as a spring casing, is released, this return spring reengages the release lever with the locking rocker. The return of the release lever in known designs is achieved in that the release spring is not relaxed in any position of the release lever or of the spring casing. Rather, the release spring is, for construction reasons, increasingly tensioned during intentional release. It is therefore also necessary to overcome the tensioned state of the release spring in the locking notch of the locking rocker when stepping into the ski binding again.

The object of the invention is to improve a ski binding of the type mentioned at the outset so that, after intentional release, it is possible to bring the ski binding into a step-in readiness state and to close the sole holder again with low forces. The goal is to be able to do so.

According to the invention, this problem can be solved by providing a stopper in the stationary part of the heel piece, so that the web can be removed from the locking notch of the locking rocker and the sole holder can be placed in the closed and open positions. The spring casing abuts or comes into contact with said stop in the supporting region during the intentional release phase between the sole holder and the spring casing during the subsequent intentional release phase. The problem was solved by performing relative motion.

Due to the embodiment of the invention, upon intentional release of the sole holder by actuating the release lever, the heel piece is automatically brought into readiness for step-in. The pivoting movement of the spring casing is limited by the stopper, and the spring casing is kept immovable relative to the sole holder, so that the pivoting of the locking rocker away from the web prevents the locking rocker from locking. This is done in such a way that it is possible to reintroduce the web into the notch without activating the release spring, ie without any force in practice. The heel piece is closed by simply pivoting the sole holder downwards. However, manual closing can also be carried out 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, the sole holder is pivoted downwards, and the release lever is then pressed down. The heel piece is then brought into a closed position. The heel piece thus has all the advantages of known ski bindings. In addition, the operating comfort of the ski binding is significantly improved in this case.

A particularly advantageous and simple embodiment of the invention is characterized in that the stop is formed by the pivot of the sole holder, which is supported on a bearing block. This allows using a special member as a stopper,
It becomes unnecessary to fasten this element to the area of stationary position of the heel piece, for example to the bearing block.

A further embodiment of the invention is characterized in that a support area for the spring housing is provided on the cover of the spring housing, and that this support area is preferably of elastic construction. In this way the spring casing can be used to form a corresponding stop without major modifications in the heel piece. Furthermore, in this case it becomes possible to arrange and install additional springs that help to return the spring casing.

According to an advantageous embodiment of the invention, the supporting 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 contacts the stop. The spring is therefore 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 wants to be able to have a wide range of choices regarding the configuration of the inner area of the heel piece and to have large tolerances regarding the configuration and arrangement between the stop and the supporting area of the cover.

According to the invention, the object is such that the stop 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. Furthermore, somewhat larger tolerances are obtained without affecting the mode of action. The heel piece can be constructed in a particularly simple manner without major modifications to construct the stopper. Furthermore, another possibility is obtained for arranging an additional spring to assist in the return of the spring casing. In this case, this spring is easy to replace. This makes it possible to change the spring characteristics or easily replace broken springs if necessary.

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 base plate or the bearing block and is preferably slidably guided in this region. be. In this embodiment, the elastically supported stop or its spring is particularly simple. Furthermore, this spring is only tensioned after the pivoting movement of the spring housing when it rests on the stop.
This ensures that 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 stop is constructed in one piece with the base plate or with the retaining plate of the bearing block. This configuration is advantageous for manufacturing reasons. Of course, this design 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.

A feature of another embodiment of the present invention is that the shaft holding the locking rocker 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 of the sole holder, and the sole holder has a recess in the form of a cutout in each case for a pin fixed to the release lever. be. With this configuration of the invention, the heel piece can be released intentionally both by pushing down towards the release lever and by pulling it. When releasing the tension, the shaft holding the locking rocking body acts as the pivot axis of the release lever, and when releasing the shoe sole, the pivot axis of the sole holder acts as the pivot axis of the release lever. In this case, a relative movement between the shaft holding the locking rocker and the release lever is made possible by the two elongated holes in the release lever. In both cases, the heel piece is ready to step in after intentional release.

In one embodiment of the invention, the area of support 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 results in a good force distribution during depressing and releasing.

In order to be able to close the sole holder from the release position in this embodiment with a small force, according to another embodiment of the invention, both of the release levers It is provided that the pivoting range of the release lever defined by the slot can be brought out of action by a deliberately actuated locking element. This makes it possible, as already mentioned, to close the heel piece with only a small amount of force while the locking element is active.

According to one embodiment of the invention, this locking member is mounted on the release lever so as to be movable in its longitudinal direction.
It is formed by a spring-loaded slider. The slider has an actuating projection on one end that can be grasped by hand, and at least one hook-like gripping member on the other end, which actuates the slider. It is designed to grip the shaft of the locking rocking body.

A more easily installed locking member is a spring-loaded slide mounted on the release lever so as to be movable in its longitudinal direction and having an actuating lug at one end that can be gripped by hand. The other end is split into a fork shape, and has two support members extending on the sides of the locking rocker, and these support members actuate the slider to rotate the shaft of the locking rocker. It can be constructed of a type that is brought under the locking rocker and supports the locking rocker from below.

Furthermore, what is important for the invention is the force of the elastic stopper, for example the spring of the stopper or the spring that loads the locking rocker provided on the sole holder.
e.g. the force of a foot spring or the elastic support area of a spring casing, e.g. an elastic tongue, a leaf spring,
The elastic additional or spring force of the cover is advantageously significantly smaller than the force of the release spring which loads the sole holder. This ensures that the spring casing can be returned in the desired manner without pivoting the sole holder upwards and thus without interfering with the release of the boot.

The ski binding shown in FIGS. 1 to 4 is constructed as a heel piece, generally designated by the reference numeral 1. FIG. The heel piece 1 has a guide rail 3 fixed to the upper side of the ski 2 by screws, not shown. On this guide rail 3, the bottom plate 4 of the heel piece 1 is guided for longitudinal movement of the ski 2 and is arranged in a manner known per se in order to adapt the ski binding to ski boots of different lengths. It can be locked in any desired position. 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 helical spring rests in a manner known per se on one end in a fixed manner on the ski and on the other end on the base plate 4 of the heel piece 1. A housing-like bearing block 5 is fixed on the base plate 4. This bearing block 5 has in its upper region a pivot shaft 7 extending transversely to the longitudinal direction of the ski and designed as a pin, on which a sole holder 6 is pivotably mounted. There is. In its upper region, the sole holder 6 carries 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. When the heel piece 1 is in the sliding position, this locking projection 9a engages under a control cam part 10, which is fixed to the front wall of the housing-like bearing block 5, as shown in FIG.

A further shaft 11 is arranged at the rear end of the bearing block 5 and extends transversely to the ski length. This shaft 11 is provided for pivotably supporting a spring housing 12 in the side wall of the bearing block 5. The spring housing 12, which is approximately U-shaped in plan, has longitudinal guides 12a for the webs 13 on both side walls. The web 13, which extends transversely to the longitudinal direction of the ski, is wedge-shaped on the one hand and has a flange-like extension in the region opposite the wedge-shaped region. A spring plate 14 is supported on this extension, on which one end of at least one release spring 15 is supported. The second end of the release spring 15 is supported by a spring receiver 16. This spring support 16 can be adjusted in a known manner in the axial direction of the release spring 15 by means of a screw 17 which is rotatably mounted in the spring housing 12.

The locking rocker 9 forms a locking notch 9b for the web 13. The web 13 is pressed into this locking notch 9b by the action of a release spring 15. Adjacent to the locking notch 9b, a recess in the form of a cutout 9c is formed in the locking rocker 9. In this recess 9c the web 13 is temporarily locked in a manner that will be explained later during intentional release of the sole holder by actuating the release lever 18.

A release lever 18 that grips the sole holder 6 from the side as well.
is pivotally connected to a shaft 8 disposed on the sole holder 6. A locking rocking body 9 is also rotatably supported on this shaft 8. A pin 19 fastened 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 formed by an elongated hole 6b provided in the sole holder 6 and extending concentrically with respect to the shaft 8, and a substantially arc-shaped slide guide provided in the tongue-shaped addition of the spring casing 12. It penetrates through the portion 12b.

The control cam part 10 cooperating with the locking rocker 9 forms, seen from the ski surface, a control surface 10a which is initially gripped in the sliding state of the heel piece 1 by the locking projection 9a of the locking rocker 9. There is. The control surface 10a of the control cam part 10 defines the elastic range of the heel piece 1 and transitions into the cam section 10b away from the ski surface via a bend that determines the release point.
This cam section 10b has a sole holder 6 in the upper region.
It has a locking range 10c that is inclined toward.

The sole holder 6 is acted upon by a release spring 20, which is designed as a spring with legs, which loads the sole holder 6 in the releasing direction. This opening spring 20 is located in the upper end region of the control cam part 10 in its recess and rests on the sole holder 6 on the one hand and on the bearing block 5 on the other hand. Shoe sole holder 6
The stopper for upward pivoting is the bearing block 5.
It is formed by the bent portion 22 of. This support block has an additional part 6c fixed to the sole holder 6.
comes into contact 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 and is fixedly connected to the spring housing 12, for example by rivets. The cover 23 pivots together with the spring casing 12. cover 23
has a window with a scale. This scale is provided to indicate the adjusted spring force.

A plastic cover 23, which covers the spring housing 12 from above, has an extension beyond the end area facing the locking rocker 9. This extension is formed by a slightly curved elastic tongue 23a several millimeters wide. The elastic tongue 23a is located at a distance from and below the pivot axis 7 of the sole holder 6 when the heel piece is in the sliding position shown in FIG. There is.

The shown heel piece acts as follows: When a vertical force is applied to the sole holder 6 from a ski boot (not shown) placed in a ski binding, the sole holder 6 moves around the pivot axis 7. It pivots upwards as a center. During this pivoting movement, the locking rocker 9 slides along the control surface 10a of the control cam part 10 fixed to the bearing block and moves the web 13 against the force of the release spring 15 into the longitudinal guide of the spring casing 12. Push back in 12a. The locking rocker 9, which is under the action of the release spring 15 and can pivot together with the sole holder 6, also pivots the spring housing 12 about the axis 11. When the locking lug 9a of the locking rocker 9 passes the release point of the control cam part 10 and the elastic range is exceeded, the sole holder 6 is swiveled into the release position with the aid of the release spring 20. In this release position, the locking projection 9a of the locking rocker 9 is brought into contact with the locking area 10c of the control cam part 10. In this case, the release spring 15 is such that the web 13 is located in the longitudinal guide 12a of the spring casing 12.
It rests in the end region facing the locking rocker 9. As a result, the ski binding is in the step-in ready state shown in FIG. Closing the ski binding from this position with a ski boot is simply carried out by pushing the sole holder 6 down into the position shown in FIG.

If it is desired to manually release the heel piece 1, the release lever 18 is pivoted, for example by hand, in the direction of the arrow _F1 shown in FIG. At this time, a long hole 6 extending concentrically with respect to the shaft 8 of the sole holder 6
By the pin 19 moved upwards in b.
The spring casing 12 is also pivoted upwards about the axis 11. In this case, web 1
3 is released from the locking notch 9b of the locking rocker 9 against the force of the release spring 15. This release is ensured by the wedge surface of the web 13 sliding over the limiting surface above the locking notch. After releasing the release lever 18, the web 13 is pushed forward under the action of the release spring 15 in the longitudinal guide 12a of the spring housing 12 until it abuts the end regions of both longitudinal guides 12a. This course of movement is controlled by a suitably designed notch 9c of the locking rocker 9, which is connected to the locking notch 9b.
made possible by The locking rocker 9 engages the control cam portion 10 as shown in FIG. 3 under the action of the opening spring 20 when the sole holder 6 then moves upwards, as shown in FIG. is pivoted away from the control cam part 10 until it can reach the top past the locking projection 9a of the cam.

Actuation of the release lever 18 and subsequent automatic upward pivoting of the sole holder 6 results in the next stage of intentional release.

In the first step, the release lever 18 is pulled upwards. In this case, the web 13 is released from the locking oscillating body, so that the sole holder also lifts up somewhat from the closed state, resulting in the state shown in FIG. 2. Furthermore, as can be seen in FIG. 2, the elastic tongue 23a of the cover 23 is in contact with the pivot 7 of the sole holder 6. In this case, the tongue 23a is somewhat tensioned, as can be seen from a comparison of FIGS. 1 and 2.

In the subsequent third stage of intentional release (not shown), the pin 19 reaches its highest position in both slots 6b of the sole holder 6. 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 release spring 20 as shown in FIG. During the pivoting of the sole holder into this position, the locking rocker 9 is in the highest position and the spring casing 12 is pushed downwards by the relaxing force of the elastic tongue 23a of the cover 23 and the web 13 is again brought into the locking notch 9b of the locking rocker. Of course, such a return pivoting of the spring casing 12 can only occur if the skier releases the release lever 18 and the release lever 18 is pivoted back into the closed position about the pin 19 as shown in FIG. It will be done. As a result, the heel piece is brought to a step-in ready state.

The configuration of the components that cooperate with each other, for example the course of the cam section 10b of the control cam part 10, ensures the above-mentioned movement course. In the release position of the heel piece 1 shown in FIG.
a is the control cam part 10 fixed to the bearing block;
is in contact with the locking range 10c. The space obtained in this way allows the web 13 to exert no force solely on said space, i.e. the release lever 15
This is important for the invention since it is possible to reach the locking notch 9b of the locking rocker 9 again without activating the locking rocker.

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 manually 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 using significantly less force. For this purpose, starting from the position shown in FIG.
8 is pivoted upwards. 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 a small force of the opening spring 20 has to be overcome compared to the releasing spring. By means of the release lever 18 being pivoted back into the closed position, for example by hand, the web 13 is again brought into engagement with the locking notch 9a of the locking rocker 9. During this operation, 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. Furthermore, it is advantageous that the heel piece can be closed in this manner also for fitting the ski binding to the length of the ski boot.

The embodiments shown in FIGS. 5 to 7 show the shoe sole holder 1.
1 to 4 only in that the bearing block 5 is supported on a transverse shaft 111 in the rear region of the bearing block 5. Horizontal axis 1
11 also in this case holds a spring housing 112, as already mentioned. Due to this arrangement, however, the pin 19 passes through the slide-shaped recess 106b of the sole holder 106 on the one hand. This cutout 106b extends concentrically with respect to the shaft 8 in an area adjacent to the release lever 18. Furthermore, the pin 19 is connected to the spring casing 1 on the other hand.
Elongated holes 1 provided in each of the 12 tongue-shaped additional parts
12b, respectively. Moreover, in this case, the locking area 10c of the control cam part 10, which is inclined towards the sole holder 106, is no longer necessary.

The area of the plastic cover 23 which covers the spring casing 12 from behind extends beyond its end area to the base plate 4 or the retaining plate 5 of the bearing block 5.
It has an additional part 33 facing toward a. In this case, the holding plate 5a of the bearing block 5 has a stop 34 in its rearwardly extending region. As shown in FIG. 5, the end region of the holding plate 5a itself can be constructed or act as a stop. When the heel piece 101 is in a sliding state, the end area of the additional part 33 of the cover 23 is connected to the retaining plate 5.
It is located at a distance from the stopper 34 of a.

The mode of action of this illustrated heel piece 101 corresponds to the mode of action already described in the case of unintentional release.

When opening the heel piece 101 manually, the release lever 18 is pivoted upwards, for example by hand, in the direction of the arrow F ₁ shown in FIG. In this case, the locking rocker 9 and the web 13 are released as described above. The actuation of the release lever 18 and the subsequent automatic upward pivoting of the sole holder 6 in this embodiment result in the following deliberate release step. Two of these deliberate release steps are illustrated in FIGS. 6 and 7.

In the first step the release lever is pulled upwards. The web 13 is connected to the locking notch 9b of the locking oscillating body 9.
The locking lug 9a of the locking rocker 9 can move away from the control surface 10a of the control cam part 10 without resistance. When the user completes this operation, he releases the release lever and the release lever is pivoted back to the closed position about pin 19. Said position of the release lever is shown in FIG. In FIG. 7, the heel piece as a whole is in a state that will be described later.

In FIG. 6, the release lever 18 is still held by the user, but the locking rocker 9 has released the sole holder 106, which absorbs the force of the release spring 20. A deliberate release stage is shown that allows for upward pivoting from the closed position. In this case, the sole holder 106 is locked with the shaft 8 by the rocking body 9.
is carried upwards. The locking rocker 9 itself is secured to the spring casing 11 by means of the abutting web 13.
Rotate the two together. Figure 6 shows the sole holder 10.
6 shows an intermediate state before reaching the highest position. However, in this case, the additional part 33 of the cover 23
is in contact with the stopper 34 of the holding plate 5a, so
The spring casing 112 cannot be pivoted any further. Under the action of the release spring 20, the sole holder 106 pivots further upwards and carries the locking rocker 9 likewise upwards.

In the next release phase, which is not specifically illustrated, the pin 19 reaches its end position in the two slots 112b of the spring housing 112. In this case, the sole holder 106 and the locking rocker 9 occupy the highest position. At this time, the web 13 and the control cam portion 1
The spacing existing or generated between the cam section 10b and the cam section 10b ensures an unhindered and easy sliding movement of the locking rocker.

The fourth stage of intentional release 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 located again in the locking notch 9b of the locking rocker 9.
That is, the locking rocker 9 is swiveled back and supported by the web 13 and held in a suitable position for stepping in again. By pressing down on the protrusion of the sole holder with the heel of the ski boot, the heel piece 101 is closed, as already described for unintentional release, and brought into the position shown in FIG.

In addition, the sole holder 10 immediately releases the release lever 18 when the user releases the release lever 18.
6, it is automatically returned to the closed state and rotated. The automatic return pivoting of the release lever 18 takes place in both sliding guide cavities 10 of the sole holder 106.
6b, pin 19 and release lever 18.

The dimensions of the components that cooperate with one another, for example the course of the cam section 10b of the control cam part 10, ensure the movement course described here as well. Shoe sole holder 10
In the released state of the heel piece 101 in which the heel piece 6 is completely pivoted upward, the locking rocking body 9
The locking projection 9a of the control cam part 10 is directed forward in the direction of the free end of the cam section 10b of the control cam part 10 fixed to the bearing block in order to reengage the web 13 in the locking notch 9b of the locking rocker 9. You can move towards. In this case, this locking notch 9
The upper limit of b must be overcome. The cavity obtained in this way allows the web 13 to reach the locking notch 9b of the locking rocker 9 only by means of this cavity without applying any force again, i.e. without activating the release spring 15. This is important to the present invention because it can be done.

FIG. 8 shows a modified embodiment of the heel piece 201 shown in FIGS. 5 to 7.
In this case, a further weak spring 8a is provided on the shaft 8, which loads the locking rocker 9 in the direction of the spring housing 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 the sole holder 106
It is advantageous if the arrangement is such that when the locking rocker 9 pivots upwards, the web 13 of the spring housing 112 is compressed after being pushed forward. This causes spring 8a
When the sole holder 106 further pivots upward, the locking rocker 9 is pushed toward the web 13. As a result, the restriction of the locking notch 9b of the locking rocker 6 is forcibly overcome. The freezing of the area of the control cam part 10 therefore causes the locking rocker 9 to become hooked there, thereby preventing the engagement between the web 13 and the locking notch 9b of the locking rocker 9, which is necessary for the step-in readiness state. This prevents the combination from occurring.

9 and 10 show modifications of the third embodiment of the heel piece. As can be seen in FIGS. 9 and 10, the stop 134 is supported by means of a spring 35 in the rear end region of the retaining plate 105a of the bearing block 105. In this case, the end region of the holding plate 105a is designed as a sliding guide for the stop 134. The additional portion 33 of the cover 23 is attached to the stopper 134 in the state shown in FIG.
, and has already pushed this stopper 134 somewhat forward against the force of the spring 35. The illustrated state of the heel piece 301, which is only partially shown, therefore means that the spring casing 11
This substantially corresponds to the situation shown in FIG. 6 of the previously described embodiment, with the difference that 2 has not reached its highest position. According to FIG. 10, the spring casing 1
12 has already reached its highest position. This situation substantially corresponds to the situation shown in FIG. heel piece 3
The structure and mode of operation of 01 are the additional part 3 of the cover 23.
3 takes place 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 takes place under the action of the spring 35. The structure and mode of operation are substantially similar to those of the first embodiment, except for the difference that the second embodiment is similar to the first embodiment. In this case, the dimensions in this range can be made with somewhat greater freedom than in the embodiment with a stationary stop. Therefore, the action of spring 35 is similar to that of spring 8 in FIG.
This corresponds to the effect of a.

It should be noted with respect to this embodiment that the force of the spring 35 is advantageously significantly lower than the release spring 20 of the sole holder 106, which may be detrimental to the release process during intentional or unintentional release. No adverse effects are caused or the release process is disturbed.

Therefore, even after intentional release, the heel piece 10
1,201,301 is in the step-in preparation state as already mentioned, and the ski boots are attached to the sole holder 10.
The heel piece can be closed by simply pushing it inside 6.
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, the heel pieces 101, 201, 301 can also be brought into the closed state with a slight force, in the same way as the heel piece 1 of the first embodiment. The process for this 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. The sole holder 6' is constructed higher than in the first embodiment, so that there is a gap between the locking rocker 9 and the upper cover of the sole holder 6', as will be described in detail later. The slide 28, which is fixed to the release lever 18', can perform an unhindered pivoting movement. 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 26. , the elongated hole 26 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 supported from above on the pivot shaft 7 of the sole holder 6' via both side walls. 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; 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, instead of the elastic tongue 23a of the first embodiment, a leaf spring 23'a is used, which is fixed to the cover 23' of the spring housing 12, for example by a rivet 23'b. .

On the lower surface of the release lever 18', the slider 2
8 is supported so as to be movable in the longitudinal direction of the release lever 18'. Release the slider 28 with the lever 18'
For this purpose, one or more guide tongues 29 are provided which hold the slider 28 on the underside of the release lever 18', as shown in FIG. 11, for example. The slider 28 itself is the release lever 1
8' and extends over the upper side of the locking rocker 9 in the direction of the sole holder 6' beyond the end region of the release lever.
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-like 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, a locking rocker 9 and a control cam part 1 are provided.
0 has a notch (not shown) in the center. The slider 28 is held by a spring 30 with the gripping member 28a in front of the shaft 8, as shown in FIG. The spring 30 is configured as a pressure spring and is arranged in a recess in the slider 28 and is attached to the slider 28 at one end and to the slider 28 at the other end.
The release lever 18' is supported by an additional support portion 18'a that protrudes into the notch of the release lever 18'. Furthermore, the slider 28 is provided with an operating projection 28b for grasping by hand.

This heel piece can be released intentionally either by pulling on the release lever 18' or by pushing it down. Release lever 18'
When releasing by pulling in the direction of arrow _F2 in Fig. 1, the release lever 18' is the release lever 1.
8' is supported on a shaft 8 which acts solely as a pivot axis. 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 done in accordance with FIG. This can be done in the format described in the embodiments up to FIG.

When the heel piece is released by pressing down on the release lever 18', for example with a ski, ski boot, ski stock, etc., the release lever 18' is pivoted downward in the direction of arrow _F3 in FIG. . In this case, the release lever 18' rests on an axle 7 fixed to a bearing block. This shaft 7 serves both as a pivot for the sole holder 6' and also as a pivot for the release lever 18'. Release lever 1
The relative movement between the shaft 8 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'. pin 19
The spring housing 12 is also pivoted upwards about the shaft 11 via the spring housing 12 . In this case the web 13 is released from the locking notch 9b of the locking rocker 9 against the force of the release spring 15 and then the locking rocker 9 is cut off as already described in the first embodiment. It reaches the range of notch 9c. 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, about the pivot axis 7. be rotated upwards. At the same time, the locking rocker 9 pivots somewhat backwards and the shaft 8 holding the locking rocker 9 slides somewhat upwards in the elongated hole 26. When the sole holder 6' reaches a predetermined rotation angle, the control cam portion 1
A locking rocking body 9 that slides backward along 0
grabs Web 13. This web 13 is swiveled upwardly about the axis 11 together with the spring housing 12 while sliding along the locking rocker 9. As the spring casing 12 pivots, the pin 19 fixed to the release lever 18' also pivots upwards. In this case, the release lever 18' is pivoted upwards in the direction of arrow _F2 in FIG. It will be done. When the release lever 18' is pivoted anew, it leaves the pivot axis 7. The locking rocker 9 is pivoted upwards together with the sole holder 6' beside the control cam part 10. During the last stage of the upward pivoting of the sole holder 6', the leaf spring 2, which is fastened to the cover 23' of the spring casing 12 and has been tensioned during the aforementioned movement course,
3'a becomes active and pushes the pin 19 and thus the spring casing 12 downwards. As a result, the web 13 is again pushed into the locking notch 9 of the locking rocker 9.
Slide into b. This also brings the release lever 18' holding the pin 19 into the closed position, so that the heel piece 1' is ready to step in.

The heel piece, now ready to 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. Slider 28
is grasped by the hand and pulled away from the sole holder 6' against the force of the weak spring 30. At this time, the hook-like gripping member 28a grips the shaft 8, so both elongated holes 26 become ineffective. Slider 28
In this state, the release lever 18' is pivoted upward until the web 13 is again released from the locking notch 9b of the locking rocker 9. 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. Then release lever 1
8' is manually swung into the closed position together with the actuated slide 28. In this case, the web 13 is again engaged with the locking notch 9b of the locking rocker 9. Although this engagement takes place against the force of the release spring 15, the force required is significantly lower than with a sole closure effected via the sole holder 6'.

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 manually 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, by constructing the operating range of the slider 28 as its own component, and by constructing this component as a two-armed lever pivotally connected to the slider 28, with one lever arm acting as an actuator. This is possible due to the fact that the other lever arm is configured such that it has a section and is biased toward the underside of the release lever 18' by another spring, and the other lever arm is configured to move away from the underside of the release lever 18'. be. In this case, the second lever arm rests, for example, on the pivot shaft 7 while pressing down on the release lever 18', so that the lever is pivoted and the lock is automatically released.

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

In order to lock the shaft 8 in such a way that the sole holder 6' can be easily closed, the slider is provided with two lateral support tongues which can be actuated by the slider. It is also possible to bring the sides of the locking rocker under the shaft 8 so that the shaft 8 is supported from below. In this case, due to space considerations, the support tongue provided in the end region of the slider is
When the heel piece is in the sliding position shown in FIG. 11, it is advantageous if it is located to the side of the locking rocker 9 and behind the shaft 8. In this case, the slider must be moved towards the sole holder.
Also, instead of the support tongue, the slider is located in the region of the rear axis 8 of the locking rocker 9 in the unactuated state, and on the side of the locking rocker 9 the shaft 8 of the locking rocker 9 is located.
A gripping member can also be provided which is movable towards the.

The heel piece 1'' shown in FIG. 12 substantially corresponds to that shown in FIG. 11. Therefore, in the following description only the points that differ from the embodiment shown in FIG. 11 will be mentioned. The main difference with Fig. 11 is that the inner end region does not have a stopper, and the outer end region bent forward at the rear has the same shape as shown in Fig. 5 to Fig. 10. This is the structure of the cover 23' having an additional portion 33'.

The resilient support of the cover 23' for the stop 134 shown in FIGS. 9 and 10 is provided by a spring 35.
In contrast to the embodiment in which the cover 23' of the spring casing 12 is provided with a rubber spring 35', which is fixed to the extension 33' of the cover 23', for example by a rivet 23'c. It is being
Due to this modification, during a deliberate release process, the rubber spring 35' is tightened and the web 13 is pulled down by pressing down on the pin 19, as leaf spring 23'a does in the embodiment of FIG. Locking rocking body 9
into the locking notch 9b. 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 shaft fixed to the sole plate, and a control cam is provided in the front end region 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 . The measures necessary for this purpose are well known and are therefore 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. 11 in the embodiments of FIGS. It is also possible to use a spring configured as an addition to the cover in the embodiment described above.

Furthermore, the mechanical spring on the retaining plate 5'a of the bearing block 5' can also be replaced by another elastic member, for example a rubber spring. However, instead of a rubber spring in the extension of the cover, the extension or its end region itself can be provided, for example, with a transverse groove in the end region that facilitates deformation, but is thereby permanently attached to the plastic material of the cover. It can also be constructed elastically, such that no significant deformations, such as cracking or breakage, occur. Furthermore, Figure 11 or 1
In the embodiment shown in FIG. 2, it is also conceivable that the locking member of the shaft of the locking rocking body is constituted by a pivot lever.
