Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heel piece for a safety ski/indicator, which is mounted on a support base and pivots about a pivot axis extending laterally. the sole retainer is held in the sliding position by a locking rocker which is under the action of a release spring and is pivotably mounted on the sole retainer;
The locking rocker has on one side a locking projection that engages from below a control cam arranged on the support in the sliding position, and on the other side has another projection and a locking part; A locking member is slidably guided in a spring casing which is supported on a transversely extending shaft in the bearing base and receives a release spring, the release spring of the locking member being slidably guided. When the opposite side is placed in the sliding position of the heel piece, it engages with the intermediate part between the locking part and the protrusion of the locking rocker, and the sole of the shoe is used to intentionally release the heel piece. This invention relates to a type in which a release lever is supported on the presser foot, and the release lever is connected via a pin to a spring casing under the action of an upright spring.

PRIOR ART A known heel piece of the type disclosed in Austrian Pat. In one embodiment, the axle is spaced apart from the axis of the locking rocker, and the locking portion locks the locking member against upward pivoting in order to allow light depression of the boot. It can be rotated from the current position using a release lever. In a further embodiment, the axis of the locking rocker is at the same time the axis of the cock part, which is constructed in one piece with the release spring.

Problems to be Solved by the Invention In the first embodiment of the known heel piece, the construction of the heel piece is somewhat complicated due to the fact that the locking part is arranged on a separate shaft supported on the locking rocker. Therefore, the production cost also increases.

Furthermore, in the second heel piece, the axis of the locking rocker is also the axis of the locking part which is integrated with the release lever, so that this heel piece is certainly structurally simple; The heel piece of the first embodiment is similar, but has the following drawback: Any opening operation requires a preceding separation rotation of the locking part, so it is not always possible to intentionally open the heel piece. It has the following drawbacks. This procedure of pivoting the locking part away before the opening operation, however, requires the skier to become accustomed to the new mode of operation. Also, in some cases, the force component acting on the locking part due to the release spring pushes the locking spring back against the force of the weaker spring, thereby releasing the locking rocker and causing the heel piece to be released undesirably. Sometimes it happens.

It is therefore an object of the present invention to improve the known heel piece of the type mentioned above so that it can be operated selectively by means of a universal release lever against the force of a lease spring or by means of a separate actuating component. Therefore, it is an object of the present invention to provide a heel piece that can be opened with a small force.

Means for Solving the Problem In order to solve this problem, the invention provides that the locking part consists of two parts, the first of which serves for the locking of the locking part, and A second part, which is mounted on the shaft of the locking rocker and can be moved by hand, releases the first part and, if necessary, the locking part 1.
The locking rocker is configured to operate to pivot the locking rocker away from the control cam following release of fl.

Embodiments of the Invention There are various structural solutions for realizing the idea of the invention. For example, in some embodiments, the first element is designed as a six-armed lever or as an angle lever, which lever is mounted on a pivot for the locking rocker and which supports the lever. It is under the action of a spring that tries to push it into the locked position. In this way, it is particularly advantageous to ensure, on the one hand, a reliable locking of the locking element in the sliding position of the heel piece and, on the other hand, easy release of the locking element.

In this embodiment, it is particularly advantageous if the first part is supported on a laterally extending shaft in the locking rocker, which shaft is located at a distance from the axis of the locking rocker. . In this case, the area of the first member extending from the pivot axis toward the locking member is configured in a prismatic manner, and one prism surface is in contact with the locking member in the sliding position of the heel piece. , the second prism surface is in contact with the non-hand operated arm of the angle lever;
Advantageously, the third prismatic surface is in contact with the stop surface of the locking rocker.

In a further embodiment, the first element is configured as a slide which is slidable in a guide provided on the locking rocker in the direction of the longitudinal axis of the guide. In this embodiment, the flat end face of the slider, which is assigned to one arm of the angle lever, is inclined with respect to the longitudinal axis of the locking rocker, and the other end face of the slider is attached to one arm of the angle lever. In the sliding position, it is advantageous if there is a defined spacing from the end of the guide on the locking rocker. Furthermore, the end of the lever arm of the angle lever adjacent to the slider terminates in a flat end surface which, in the sliding position of the heel piece, extends parallel to the end of the slider and is attached to the end surface. It is advantageous to be in contact.

However, it is not necessarily necessary that the lever arm facing the slider has a flat end surface; for example, the end of the lever arm facing the slider of a six-armed lever is Embodiments are also possible in which the surface ends in a rounded curve. In this embodiment, the slider may be in contact with the end of the guide provided on the grandstand rocking body at the sliding position of the heel piece, and in this case, when the release motion is introduced, the slider is There is no need to move away from.

It is also advantageous in this embodiment if a hinge plate with an elongated hole is pivotally mounted on the sixth arm of the lever, the elongated hole being penetrated by a pin screwed into the locking rocker. . With this configuration, on the one hand, the pivot angle of the lever relative to the locking rocker is limited to the required value, and on the other hand, the locking protrusion of the locking rocker becomes stuck to the control cam due to freezing. Even in this case, the pivoting movement of the lever can be followed by a pivoting of the locking rocker and thus a separation of the locking rocker from the control cam.

In a further embodiment of the invention, the first part and the second part are mounted pivotably on the shaft of the locking rocker, the first part being mounted via a hole in the bearing eye. Moreover, a second member, which is substantially U-shaped when viewed from the front, is rotatably supported through elongated holes cut out in both legs.

With this configuration, on the one hand, the member that works to lock the locking member can be reliably fixed in the sliding position, and on the other hand, when it is desired to intentionally release the heel piece, the above member can be can be returned to its non-active position in a positive manner.

It is also possible to provide friction surfaces on both parts that prevent the manually movable part from automatically moving from one end position to the other, but such a solution is, however, prone to failure. Easy to wake up. For this reason, in a preferred embodiment of the invention, the locking rocker and the second part are each provided with an extension, the bisexual extensions each having at least one pin, which pin is adapted to move in order to support the pressure spring which attempts to press the second member upwardly.

The upper end position is therefore brought about by a pressure spring which, after manual release of the second part, moves this second part and the other part connected to it back into the starting position.

In this embodiment, it is advantageous if the axis of the pressure spring is arranged at a distance from and intersects with the axis of the locking rocker. In this way, a torque is always applied to the second member which tends to press the free end of the leg towards the locking rocker. In this case, protrusions are arranged on the inside of both legs of the U-shaped second member, and in the sliding position of the heel piece, the protrusions are attached to the stop surface of the locking rocker under the action of a pressure spring. Advantageously, the first member is guided along the guide surface of the locking rocker during the intentional release of the heel piece. In this way, only one surface is sufficient to guide one of the protrusions.

According to a further embodiment, the legs of the U-shaped second member have inwardly extending projections that engage the first member, e.g. It has a shaped protrusion. With this embodiment, a positive displacement of the first part from the locked position is ensured.

The first member may be in the form of a plate; however, the first member is configured as a generally rectangular frame, with the vertically extending long sides of the frame pointing upwardly. Advantageously, it is extended and forms a bearing eye, which bearing eye is penetrated by the shaft of the locking rocker. This provides, on the one hand, a sufficiently dimensionally stable construction of the first part and, on the other hand, a lateral guidance of the first part along the locking rocker.

In this embodiment, the first member is supported on the shaft of the locking rocker, and the second member is guided between the free end of the first member and the stop surface of the locking rocker. It is advantageous if the slider is designed as a slider with a In this case, the lower end of the slider is constructed with a thick wall, and the difference between the width of the thick wall and the width of the slider, viewed in the direction of the axis of the locking rocker, is
It is advantageous if, in the sliding position of the heel piece, the first part corresponds to a distance which projects beyond the side of the locking rocker facing towards the locking element. With this construction, the structure of the heel piece can be simplified and its production costs can be kept particularly low. In a further advantageous embodiment, the slide is guided in a groove of the locking rocker and is bent at the end of the slide which projects upwardly from the internucleus and is actuated by the skier's hands. If the end of the slider is bent in this way, on the one hand it is easier to manipulate the skier's hands, and on the other hand it is possible to limit the travel distance of the slider in one direction.

Example In FIG. 1, the entire heel piece is indicated by numeral 1.

A guide rail 3 is fixed to the upper side of the ski 2 via a screw (not shown), and the base plate 4 of the heel piece 1 is slidably guided along the guide rail 3 in the longitudinal direction of the ski. A thrust spring or the like is supported on the idle rail 3 depending on the size of the ski boots used. A housing-like bearing 5 is fastened to the base plate 4 and has a laterally extending pivot shaft 7 in its upper region.
A shoe sole presser 6 is rotatably supported on the holder. A shaft 8 is arranged in the upper region of the sole presser 6, on which a locking rocker 9 is pivotably mounted. The locking rocking body 9 extends substantially downward and has a locking protrusion 9a at its lower end. This locking protrusion 9a is the heel piece 1
In the sliding position of , it engages under a control cam 10 fixed to the front wall of the support base 5 .

On the side of the support base 5 facing towards the rear end of the ski, a further shaft 11 is arranged which extends in the transverse direction of the ski.
A spring housing 12 or the like is supported on this shaft 11. The spring casing 12 is approximately U-shaped in plan and lies under the skin of the upright spring 12c. In the side walls of the spring casing 120, longitudinal guides 12a are cut out for the webs 13 which extend transversely to the ski and serve as locking elements. The web 13 has a spring catch 14 on its back side.
4 supports one end of a release spring 15. I.J.
The other end of the IJ-spring 15 is supported by a spring holder 16 whose movement can be adjusted in the axial direction of the IJ-spring 15 via a screw 17 rotatably supported on the spring casing 12 . In the sliding position of the heel piece 1, the web 13 is pressed against the locking recess 9b by the release spring 15. The locking recess 9b is the locking protrusion 9a of the locking rocking body 9.
It is located on the opposite side.

In addition to the locking rocking body 9, the shaft 8 has an IJ slipper 18.
is pivotably supported, and the release lever 18 covers the side of the shoe presser foot 6.

A pin 19 fixed to the release lever 18 in parallel to +kl+ 8 passes through an arc-shaped long hole 6b, and this long hole 6b is cut out in the side wall of the @ll' bottom presser 6. Similarly, a substantially arcuate slide guide 12b is cut out in the side wall of the spring casing 12.

The control cam 10, which cooperates with the locking rocker 9, initially has a control surface 10a, viewed from the upper side of the ski, which controls the locking rocker 9 in the sliding position of the heel piece 1. The locking protrusion 9a engages from below over a wide range.

The control surface 10a of the control f-cam 10 defines the elastic range of the heel piece 1 and, via the bend defining the release point, the section 10b which extends upwardly opposite to the ski's two sides. is moving to. This category 10
A locking area 10c that is inclined toward the sole presser 6 is provided in the upper end area of b. The sole presser 6 has a foot spring 20 which is a release spring that loads the sole presser in the release direction.
is under the action of The leg spring 20 is supported by the support base 5 at one end and by the sole presser 6 at the other end. The support base 5 has a bend 22 which forms a stop for the upward pivoting movement of the sole presser 6. That is, during the upward pivoting motion, the additional portion 6c fixed to the sole presser 6 comes into contact with the bent portion 22.

Another foot spring 21 is supported on the pivot shaft 7 disposed on the support base 5. One end of this foot spring 21 is connected to the pin 19, and the other end is connected to the upper side of the shoe presser foot 6 from below. supported by the cover. The force of the leg spring 21 is significantly smaller than the force of the leg spring 20, which is a release spring.

A cover 23, preferably made of plastic, is inserted in the rear end region of the spring housing 12. This cover 23 is rigidly connected to the spring housing 12, for example by rivets.

The cover 23 can therefore be pivoted together with the splash casing 12. The cover 23 has a window, known per se, with a scale, which window can be adjusted and serves to display the splash preload.

When an unintentional release is introduced in the heel piece 1, the sole presser 6 is pivoted clockwise about the pivot shaft 7.

During this pivoting movement, the locking rocker 9 slides along the control surface 10a of the control cam 10 fixed to the support base 5, and the web 1
3 releases the spring casing 12 against the force of the spring 15
Push back along the longitudinal guide 12a. At this time,
The spring casing 12, which is connected to the sole presser 6 via the locking rocker 9, can also be pivoted about an axis 11. When the locking projection 9a of the locking rocker 9 passes the release point of the control cam 10, the sole presser 6 is swiveled into its open position with the aid of the foot spring 20, which acts as a release spring.

In this open position, the locking protrusion 9a of the locking rocker 9 is in contact with the locking range 10c of the control cam 10. In this case, the release spring 15 can be relaxed until the web 13 rests on the end region of the longitudinal guide 12a of the spring housing 9 facing the locking rocker 9. Heel piece 1 now occupies the stepping position. By inserting and pressing down the boot, the downhill position shown in FIG. 1 is again achieved.

When it is desired to intentionally release the heel piece 1, the release lever 18 is manually turned in the direction of arrow F.

The release lever 18 is connected to the spring housing 12 via a pin 19, so that a pivoting of the release lever 18 also causes the spring housing 12 to pivot clockwise, that is, about the axis 11. This allows the web 13 to be separated from the locking recess 9b. After release of the release lever 18, the web 13 springs under the action of the spring 15 against the longitudinal guide 1 of the casing 12.
2 until it abuts the end of the longitudinal guide. This is made possible by the cutout 9C of the locking rocker 9.

During the subsequent upward movement of the sole presser 6, the locking rocker 9 is moved until the locking protrusion 9a rubs against the control cam 10 and reaches the upper part under the action of the release spring (legged spring 20).
It is possible to move away from the control cam 10. web 1 at the same time
3 is the locking recess 9 of the locking rocking body 9 under the action of the leg spring 21.
located within b. As a result, the depression position of the heel piece 1 can be obtained.

In the heel piece 1 according to the construction type shown in FIG. 1, which is not disclosed in the printed matter, the locking recess 9b is delimited on its upper side by a bulge. Based on this, when the heel piece 1 is intentionally released, the web 13 is moved by the height of the bulge IJ-s spring 15
must be pushed back against the force of

The embodiment shown in FIG. 1a differs from the embodiment in FIG. 1 in that the support 5I is pivotable about a yaw axis 4Ic fixed to the base plate 41. Furthermore, the base plate 41 has a coil spring 4 a
The guide rail is pressed against a lockable stopper through the
- supported by the rule 31. After pivoting outward to the side, the heel piece 1 is brought into the medium heat position by the return spring 51a.

At its end adjacent to the boot, the base plate 41 has a locking element 24, which is equipped with a control cam known per se with a locking area, which controls the sole valve. A roller 25 supported by the roller 6 is in contact with the roller 25. For purely lateral release, the heel piece 1 is locked by the locking area of the control cam.

A purely lateral IJ IJ-space movement is therefore taken care of by a dough piece, not shown. After the resulting oblique force has been overcome and the locking area has been overcome, the control cam causes a lateral swivel of the upwardly swiveled sole flap.

Different solutions according to the invention are described below, which make it possible to release the heel piece with significantly reduced forces.

In the embodiment shown in FIG. 2, the first member 30 is rotatably supported on the 1ii131 in a notch provided in the lower region of the locking rocker 9;
The end facing away from is shaped like a prism. Furthermore, an angle lever 32 (second member) is supported on the pivot shaft 8 of the locking portion JfNt9■, and this angle lever 32 can be rotated by hand against the force of a spring 33, which is a tension spring, for example. It is possible. In the sliding position, the lower prism surface 30a of the first member 30, which forms part of the prism peripheral wall, is in contact with the stopper surface 91a of the locking rocker 9. Another prism surface 30b following this prism surface 30a is in contact with the web 13.
3 is prevented from pivoting in the clockwise direction.

The arm 32a of the angle lever 32 that is not operated by the skier's hand extends downward, and the end surface of the arm 32a contacts a further prismatic surface 30c of the first member 30. . This prevents pivoting of the member 30 in a counterclockwise direction.

If it is desired to intentionally release the heel piece 1, the angle lever 32 is pivoted counterclockwise against the force of the spring 33. As a result, the member 30 is released, and the prism surface 30a of the member 30 is now lifted up from the stopper surface 9a of the locking rocker, and via the web 13,
Under the action of the upright spring for the spring housing 12, it is swiveled upwards. At this time, the prism surface 30b is in contact with an imaginary cylindrical body having the axis 11 as its central axis on the tangential plane. In the case of deliberate release in this way, the pivoting movement of the web 13 is not hindered. The heel piece 1 thus reaches the depressed position. If the sole flap 6 is then pressed down during a new depression of the boot, the downhill position shown in FIG. 2 is again produced.

The locking rocker glI shown in FIG. 3 also has an angle lever 32I (second member) under the action of a spring 3310; Unlike the spring 33, it is configured as a spring with legs. The locking rocker 9II has a guide 9IIa extending in the longitudinal direction of the locking rocker, and the slider 40, which is the first member, is guided within the guide 9IIa.

The slider 40 has a protrusion 41 which comes into contact with the web 13, which is a locking member, in the sliding position of the heel piece.

In this case, the lower end of the slider 40 has a distance a from the end of the guide 911a. The upper end surface of the slider 4° forms an acute angle of, for example, 700° with the longitudinal axis of the slider. The lower arm 32a of the angle lever 321 moves the slider 40 with its appropriately inclined surface when the heel piece is in the sliding position.
is in contact with the upper end surface of.

If it is desired to intentionally release the heel piece, the angle lever 32 is turned clockwise against the force of the spring 33'. At this time, the oblique end surface of the arm 32Ia of the angle lever 321 slides along the oblique upper end surface of the slider 40, and as a result, the slider 40 is pushed downward. This is made possible by the spacing a mentioned above. At the same time, the web 13 is pushed back somewhat against the force of the spring 15. As soon as the lower arm of the angle lever 321 leaves the two end faces of the slider 40, the slider 40 springs under the action of the upright spring 12a for the casing 12 (see FIG. It moves upward until it turns over the +40 protrusion 41.

This provides the stepping position.

Both embodiments shown in FIGS. 2 and 6 (differently shown in FIG. 4)
In the illustrated embodiment, a six-armed lever 321 is provided as the second member instead of the angle lever. This lever 32I is also supported by the pivot shaft 8 of the locking rocking body 9111, and attempts to rotate the lever 3211 clockwise (f).

It is under the action of Ne32IIa. The kite 9I of the locking rocking body glII] Ia has a slider 401 which is the first member.
is guided, and the protrusion 411 of this slider 40' prevents the web 13 from pivoting upward in the sliding position of the heel piece.

The slider 401 is further moved to the downhill position (X4-
It is also prevented from sliding upwardly by arm 32"aK of 321. The second arm 32IIbi↓ serves to receive the force P exerted by, for example, the tip of a ski pole. 6th arm 32IIC
A hinge plate 45 having a notched elongated hole 46 is pivotally attached to the hinge plate 45. The elongated hole 46 is penetrated by a pin 47 screwed into the locking rocking body 91. In this case, the length of the elongated hole 46 is limited to an angle that ensures sufficient sliding movement of the slider 401 for the release of the web 13.
1 is set so that it can turn (・ru.

3. If you want to intentionally release heel piece 1. By applying a pressing force to the arm 32''b of the arm-shaped lever 32III, the lever 32 is turned counterclockwise. As a result, the hinge plate 45 is first moved into the elongated hole 4.
The pin 47 of the locking rocker 9U1, which had been in contact with the upper limit portion of the elongated hole 46, is lifted against the force of a spring (not shown) until it contacts the lower limit portion of the elongated hole 46.

At this position of the lever 32■, the slider 401 is now
is lifted away from the web 13 until the slider is no longer a continuation of the web 13 (which no longer prevents it from pivoting). In this way, the open position of the heel piece 1 is obtained.

In the embodiment of FIGS. 5 and 6, the locking rocker mounted on the pivot shaft 8 is designated by glV.

The pivot shaft 8 further includes a first member 50 connected to the bearing eye 50a through a hole 50b, and a second member 60 configured in a U-shape that can be rotated through an elongated hole 61 cut into both legs 60a. is supported by. The first member 50 is in the form of a rectangular frame whose long sides extend upwardly to form bearing eyes 50a. The frame of the first member 50 is guided along the side of the locking rocker glV. The lower narrow side of the frame of the first member 50 forms a protrusion 50c that prevents the web 13 from pivoting upward in the sliding position of the heel piece. When the projection 50c pivots back, the projection 50 enters a groove glVa extending laterally in the locking rocker glV.

At a distance from its pivot axis 8, the locking rocker 9■ has an additional part glVb with at least one pin 91Vb1.
, this extension 9''b serves to support at least one, preferably two pressure springs 62, the other end of which is connected to the lateral portion 6Qd of the second member 60.
is in contact with an extension 63 which is likewise provided with at least one pin 63a. Both legs 6Da are guided along the side surfaces of the first member 50 and have tongue pieces 60b bent inward. This tongue piece 60b is the first member 50
is engaged with the long side of the rectangular frame. Furthermore both legs 6
0a has a protrusion 60c directed inward at its free end, and this protrusion 60C is supported by the stopper surface 91VC of the locking swing breakout in the sliding position of the heel piece 1. However, when the second member 60 is pushed down, it comes off the stopper surface glVC and the pressing spring 62
Since torque is applied to the second member 60 by
It is guided along a guide surface 91vd following the stopper surface 91vC.

In the heel gear 1 downhill position, all parts are as shown in Figure 6.
occupies the position shown in If it is desired to intentionally release the heel piece 1, the lateral part 60d of the second member 60 is pressed by the skier, thereby causing the second member 60 to release.
The member 60 is pushed downward until the pivot shaft 8 comes into contact with the ends of both holes 61. As a result of this movement, the second member 60
Both protrusions 60c come off the stopper surface 9IVC of the locking rocking shut-off and are guided along the guide surface 91Vd of the locking rocking body 9IV. That is, when the second part is pressed from above, it is not only shifted towards the upper surface of the ski, but is also simultaneously caused to undergo a pivoting movement in the clockwise direction as viewed in FIG. 6 about the pivot axis 8. However, the second member 6
Due to the movement of
member 50 is released, so that the first member 50 is moved from a position where it prevents the web 13 from pivoting upwards to a position where it no longer prevents the web 13 from pivoting upwardly.

In this position, both tongue pieces 60 engaged with the first member 50
b is obtained by form-fitting by pivoting the first member 50 back toward the boot.

In this case, the projection 50c enters the transversely extending groove 9rva of the locking rocker glV and releases the web 13, which can now pivot upwards unhindered.

A modified embodiment, which is somewhat simplified from the embodiment shown in FIGS. 5 and 6, is shown in FIG.

In this modified embodiment, a locking rocker 9V and a first member 70 are rotatably supported on the shaft 8.

■ The locking rocking body 9 has an additional portion 9Va extending in the lateral direction,
Similarly, the first member 70 has a laterally extending extension 71. A leg 72a of a second member 72, which is U-shaped when viewed from the front, is guided between the elbow joints 9va and 71. The ends of the legs 72a are considerably thicker.

At the downhill position of heel piece 1, this thick part is the additional part 9V.
It is located between A and 71. Since the first member 70 is under the action of a foot spring (not shown), the second member 72 is in contact with this member and the four additional parts 9Va in the sliding position of the heel piece.

71, it is held firmly by the friction between it and 71. However, if you want to intentionally release heel piece 1, the second
is pushed toward the upper surface of the neck board by the skier, and at this time, the thick portions of both legs of the second member 720 are located below the appended portion 71 of the first member 70. The first member 70 can therefore be pivoted in the clockwise direction as viewed in FIG. 7 until the web 13 is released and pivoted into the open position in which it can be released from the heel piece 1 of the boot h1.

However, when stepping on the boot again, the second member 72 must be pulled higher by hand.

The invention is, of course, not limited to the embodiments described above and shown in the drawings, but a wide variety of variant embodiments are possible without departing from the scope of the invention. For example, in an embodiment in which both members are configured in a frame shape or a fork shape and have a locking rocking body, it is possible to configure the locking rocking body in a frame shape or a fork shape and to lock both members. It is possible to arrange it inside the rocking body. Furthermore, in the heel piece of FIG. 1a, an additional lever 2γ may be supported on a separate shaft 26, in which case the lever 27 can be an operating arm of an angled lever or a six-armed lever, or as shown in the figure. This acts on the operating arm of the second member 60 of the locking rocker glV. The rest of the structure and mode of operation of the locking rocker glV correspond to those already described.

Effects of the Invention As can be seen from the above description, by dividing the function of the known locking part into two parts as in the present invention, the functions of the two parts are clearly separated, and thereby the heel piece The working format of is significantly simplified. Furthermore, the dimensions of the two parts can be tailored very precisely to the actual requirements of each part, so that material consumption can be reduced.
