Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a braking device for skis, in which the core device is separate from the ski boot, and includes an attachment for use while being fixed to the ski and said attachment in the area of the boot. a spring-loaded operating mechanism mounted to the mount, and two brake arms supported within the mount, each arm pivoting about an axis extending parallel to the longitudinal axis of the ski. The brake vane is used to rotate between the brake position and the brake position, and the spring of the spring-loaded mechanism biases the brake arm into the brake position.

A braking device for skis of this kind is known, for example from German Patent Publication DE-O 82612708, in which almost all parts of this braking device for skis include an operating mechanism in the form of an arcuate brake arm. The lever mechanism for the brake vanes is located unprotected. The brake arm itself is tiltable like a rocker arm about an axis extending laterally on the ski. In order to obtain the necessary steps to pivot the brake vanes between the braking ready position and the braking position, the brake arm must be moved when the user locks the ski while the ski braking device is in the braking position. When attempting to enter the device, the ski lock extends far up in front of the heel portion. This means the brake arm! When lowered, the brake vane means that the user's ski boot can immediately leave the braking position in contact with the ground before it is locked in the heel of the ski locking device.

1+, DE-O52612708! The braking device for skis has an expensive and complicated structure, and includes an auxiliary spring, a main spring,
It requires a complex shaped cam at the rear of the brake vane and a number of individual components including a contact plate pivoted between the main spring and the outside of the cam. The movement of the brake blades from the ready position to the braking position and vice versa is
It is not possible without crossing the critical point outside the cam of the brake vane in one direction or another.

DE-O32612708! If dust or ice collects on the rear part of the brake arm of a device that is used, the sufficient tilting movement of the brake arm is prevented, so that the so-called critical point on the outside of the cam is completely reached after the rotational movement of the brake vane begins. Therefore, the strong main spring between the two brake vanes cannot be activated to promote the rotary movement of the brake vanes. In this connection, the following must be borne in mind: That is, the movement of the brake vanes into the braking position is initiated only by the auxiliary spring, which tends to press on the brake arm of the operating mechanism, which is remote above the surface of the ski.

At the same time, the rear part of the brake arm, with respect to the outside of the cam of the brake vane, tries to take a position such that the strong main spring arranged laterally helps to flap the brake vane. However, the main spring is
It can't work like this. That is, when the main spring is not hanging on the outside of the cam at a position below the critical point,
The main spring is then positioned on the outer pivot of this cam so that the required torque is applied.

The German utility model DE-GM 70 39 190 describes a braking device for skis, which consists of only one brake blade for each ski, the brake blades extending along the length of the ski. The rotation of the shaft extending in the direction is rotatable, so variations in the braking effect must be expected. The design of the connection between the ski braking device and the heel part of the ski locking device is such that the ski braking device cannot be moved from its ready position to the braking position unless a strong force is applied upwardly to the heel of the ski boot. Therefore, the clamping projection of the braking device of the ski is released from the action of the clamping device via the element plate and the clamping lever. However, the usability of such ski braking devices is very limited and therefore does not meet the requirements of safety if the user's ski boots are no longer locked by rotational release. Yes, while the plywood remains stuck to the ski. This creates a significant danger for only the skis to slide down the mountain and for everyone else in the vicinity.

Furthermore, the ski braking device according to DE-GM 70 39 190 includes a device that automatically returns the ski braking device from the braking position to the ready position when the user steps on the locking device again with the ski boot. Not prepared. In this case, the ski brake must be manually moved into the ready position and the tightening lug of the ski brake must be tightened by the clamp before the ski brake can be operated again. Must be. As such, this type of ski braking system is not only prone to recreational movements, but also complicates handling when the user wishes to re-engage the ski locking system while outdoors on a slope. There is also.

Swiss patent CH-PS 615 349 describes a ski braking system in which a pair of brake vanes are interconnected by a rotatable screw on the side of an axis extending laterally of the ski. In the described device, the brake vanes must undergo a complex resultant movement in order to leave the ready position and reach the braking position. First a pivoting movement takes place in the horizontal plane, the brake vanes placed in a ready position on the surface of the ski pivot laterally and at the same time deform the spring steel wire; performs a pivoting movement about a laterally extending axis such that it projects beyond the underside of the brake into the braking position.

The operating mechanism according to the CH-PS 615 349 is as follows:
It consists of a pedal that fits into the brake arm and extends freely upward from the heel of the ski lock and beyond the top of the ski so that snow, ice, or dirt can There is a risk of accumulation under the ψ, which impairs the full depression of the pedal, as a result of which the brake vanes cannot be retracted sufficiently onto the surface of the ski, and the brake vanes are In between, they protrude laterally beyond the ski, creating an undesirable and dangerous obstacle. Such dangerous failures are particularly in the following cases: That is, when the user wants to step on the ski locking device again in deep snow or outdoors on a slope, and the reason is that the user is in a troubled situation. I'm aware of this, but since the operating mechanism is covered by my ski boots, I can't really see what's being pressed under the operating mechanism. A similar problem may occur when snow or ice accumulates on the surface of the ski, as it prevents the brake vanes from moving flat in both directions on the surface of the ski to the ready position. be experienced.

It is known from CH-PS 615 349 mentioned above to use a coupling element for the brake arm of two brake vanes, but the function of this articulated coupling element is that it is arranged horizontally on the surface of the ski. It simply pivots the brake vanes laterally in the plane. Pivot the brake vanes to the braking position around an axis extending laterally of the ski,
The actual pivoting movement from the braking position is also effected by a completely different structural member, namely a torsion coil spring which is wound around a laterally extending pivot axis.

German published patent publication DE-O82612770 describes a braking device for skis, and in that braking device,
The brake arm is pivotable about an axis extending longitudinally of the ski, and the brake vanes pivot about the ski as they move between a ready position and a braking position. These structures are undesirable and take up a lot of space, and the braking device of the ski is partially located in the heel portion of the locking device. Also, because they require a large number of individual elements, the braking system #i of these skis is very prone to failure during operation. The pedal-shaped operating mechanism of the ski braking device projects freely and unprotected into the area of the ski boot and is therefore not directly connected to the brake arm; it is mounted wrapped around the brake arm. connected by cable. A torsion coil spring sliding on the brake arm normally tilts the brake arm as well as the brake vane, which is securely connected to the brake arm, into a ready position. However, when the operating mechanism is released, the beda /l/ is pulled upwardly by the spring to pivot the brake arm and brake vane in the braking position.

The reason is that the pedals are connected via Google.

The structure of the ski braking device according to the above-mentioned DE-O 32612770 consists of a main spring and an auxiliary spring, a plurality of joints and support points, and a large number of connecting elements, which is complicated, occupies a large space, and Easy to break down during operation. If ice, dust or snow has accumulated under the pedal in deep snow and the operating mechanism is free and unprotected and the protruding pedal cannot be depressed sufficiently, the brake vanes may not fold at all. Because it cannot, it protrudes laterally in an outward direction beyond the side edge of the ski. Not only does this create an undesirable and dangerous hazard, but it also creates a risk of bending of the brake blades.

German published patent publication DE-OS 26 05506 describes a braking device for skis, in which a pair of brake vanes extend sideways to the ski and are connected to a crank disposed next to the ski. It is possible to pivot between a ready position and a braking position with the shaft rotation embodied by.

The crank is connected to a lever that surrounds it by a fork and projects upwardly on the top of the ski at its opposite end in the region of the heel part of the locking device of the ski. This lever constitutes a rocker arm that is used to tilt about an axis extending laterally on the ski so as to pivot the brake blades between a ready position and a braking position. The movement of the brake vanes of that arrangement from the ready position to the full braking position is ensured by an inclined surface provided for the brake vanes at the top of the gap, in order to slide into the diagonally outwardly projecting braking position. ing. If these ramps are omitted, the brake vanes, when in the ready position, project laterally into the chamber and beyond the ski, which presents an undesirable hindrance to the user. Another drawback of the ski braking device described in this publication is the following fact. Namely - the lever of the actuating mechanism of this ski braking device freely enters into the range of the ski locking device, so that ice, snow or dirt accumulates under the lever, thus preventing the proper adjustment of the ski braking device. impair function. The reason is.

This is because it is impossible to completely push down the lever, and as a result, the brake blade cannot be fully retracted.

It is certainly known from German Patent Application No. 2004-11112 to provide a brake system for skis with a crank for pressurizing the brake vanes, which crank is also arranged so as to be rotatable in the transverse direction of the ski. On the one hand, the crank is connected to an arcuate operating mechanism, which projects into the range of the locking device of the ski when it is in the braking position such that it is depressed by the ski boot. On the other hand, the crank is pressurized by a spring arrangement acting in the longitudinal direction of the ski so as to push the crank down into the braking position with the brake vanes connected thereto. The ski braking system described in this publication consists of a large number of nine individual elements, which not only complicate the structure but also limit its reliable function. This is because the levers that make up the operating mechanism protrude far above the top of the ski, a condition that increases the structural height and also makes it difficult to move the ski. This is a situation that can lead to a situation where, when a person enters the ski locking device, the ski braking device is released by simply pressing down on the operating mechanism before the ski boot is secured to the ski locking device.

This invention has been made with attention to the above points, and an object of the invention is to provide a ski locking device of the type specified at the beginning of this description. It is integrated into a compact box with a low height, allowing it to easily enter difficult terrain.

According to this invention, the above points are solved as follows.

That is, the operating mechanism consists of a box consisting of a bottom top and a top cover spanning the trough, which can be displaced along the side wall of the trough, and each crank arm is connected to each brake arm and supported within the box. and the crank arms are interconnected inside the box by a spring elastic coupling member having a U-shaped cross section and are rotatably held by the ends of the two legs of the coupling member. And,
The connecting member and the cover are pressurized by a spring located at the bottom of the trough.

The desired objective is successfully achieved with a braking device for skis according to the invention, the brake vanes of which pivot in a ready position with a simple pivoting movement, and in this position the brake vanes are Situated completely above the top of the ski without protruding beyond the side. In this way, an adverse influence on the sliding properties of the ski is avoided, and the braking device of this ski is not complex in construction.

Rather, the braking device consists of a small number of individual elements that are easily assembled and do not require special tools. Furthermore, the ski brake mounting according to the invention is a flat four assembly with individual parts protected by a box, so that during operation, dust and the like will not cause damage.

In a further development of the ski braking device according to the invention, the crank arm #'i of the brake arm can be rotated about its longitudinal axis through an angle of less than 180°, for example by 160°. This means that the crank arm does not reach top dead center and bottom dead center and that the braking function of this ski requires additional guiding surfaces on the crank arm to reliably determine the crank arm movement. It is a reliable way to ensure that quality is not guaranteed under any circumstances.

It is advantageous that the braking device for a ski according to the invention has a longitudinal axis of the brake arm, which longitudinal axis is offset inwardly and bent parallel to the side edge of the ski and at its end. A brake vane is provided, the brake vane being in a braking ready position close to the heel of the locking device and pivoting upwardly from the braking ready position to the braking position. In the braking position, the ski blades project laterally and diagonally downward from the ski in the braking position. In this way, the ski braking device according to the invention can be constructed with a narrow width, since the brake vanes are located at a relatively large distance from the side edge of the ski in the braking preparation position. It's empty.

This narrow structure consists of a transition section where the brake arm leads from its longitudinal axis to the brake vane, and with respect to the longitudinal axis of the brake arm in a plane essentially perpendicular to the plane defined by the longitudinal axis and the crank arm. A further improvement is achieved when the brake vanes are offset. The brake blade has a brake blade that is biased further inward than the longitudinal axis of the brake arm, is located at the retracted position when the brake blade is in the braking preparation position, and is formed integrally with the brake arm. are advantageous, while in the braking position these brake vanes project outwards to the extent of the offset of said transition with respect to the longitudinal axis.

Further developing the ski braking device according to this invention,
The bottom top and top cover each have a horizontally elongated hole and a vertically elongated hole in their side walls for rotatably supporting the brake arm.

This is a completely simple means of effectively supporting the brake arm without any other additional components.

Advantageously, the elongated hole of the brake arm or trough is provided with a complementary projection or recess extending transversely to the longitudinal axis of the braking device of the ski. This is a quite simple means of effectively gripping the brake arm in the longitudinal direction. If desired, grooves or ring collars can be provided in the side holes of the bottom trough or in the brake arms.

A further development of the ski braking device according to the present invention is that the cover of the operating mechanism protrudes downward from the top of the cover to receive the tightening port, thereby limiting the space for storing the connecting member. It consists of a recess containing a perpendicular ventral plate. On the one hand, this kind of profile of the cover increases its stiffness, and on the other hand, the cover itself constitutes a support for the spring-elastic connecting member, which in this way resists displacements within the cover. It can be stored in a fixed state. At the same time, the walls of the recess are
Serves as a guiding surface.

Conveniently, the trough and recess in the cover are formed with aligned openings for receiving the tightening bolts that define the travel of the connecting member and the cover. The vertical movement of the cover spanning the trough is thus limited downwards by the height of the side walls and upwards by the heads of the tightening bolts, and these movements are guided by the bottom trough. .

The guiding of the cover in vertical movement further provides a braking device for skis according to the invention, in which the space between the side walls of the cover and the adjacent belly plate of the recess substantially corresponds to the wall thickness of the side walls of the trough. It will be further improved as it is developed.

A further development of the ski braking device according to the invention provides that the bottom of the trough and/or the coupling element consists of a spring seat for biasing the coupling element. Conveniently, a spring is arranged in the center of the ski brake box, the spring seat being able to be embodied either as a protrusion projecting into the spring, or as a coil spring or a leaf spring. It can consist of an annular projection extending a certain distance along the outer radius of the spring.

It is advantageous for the coupling member of the ski braking device according to the invention that the width of the coupling member between the two legs is narrower than the space between the longitudinal axes of the two brake arms. That contributes favorably to the crank arm not reaching top dead center in the braking position, and as a result, the movement of the crank arm!
! is not adversely affected.

A special advantage is obtained because it facilitates the movement of the crank arm and the movement of the brake arm in a simple way.
This is the case when the legs of the connecting member are pressed inward against the lower side of the connecting member. For convenience, spring steel is used as the material for making one connecting member.

A further development of the ski braking device according to the invention provides that the cover is formed with sloped surfaces on its upper side and that these slopes extend flat towards the side walls of the cover. . On the one hand, this facilitates stepping on the locking device of the ski, and on the other hand, care is taken that pressure is applied via the connecting member of the cover and the crank arm, and the pivoting of the crank arm' or Guarantees rotational movement.

According to the ski braking device according to the invention, the trough has solid timber reinforcements in the region of the side walls, in which the support of the brake arm is formed. This improves the stiffness of the top and the trough can be made in one piece, for example as a casting, in a simple manner.

Overall, the ski braking device according to the invention is advantageously characterized by an operating mechanism, Fi
, the box only needs to allow rotational movement of the crankshaft with the crank arm attached, so the structural height is much lower than most commercially available designs, and operation with small strokes is possible. We provide. At the same time, it is advantageously ensured that the braking device of this ski is only released when the user presses on the ski locking device.

Hereinafter, with reference to the accompanying drawings, nine exemplary embodiments of the present invention will be described.
I will explain.

FIG. 1 shows the important components of the ski braking system, namely the bottom trough 50. Two brake arms 1G and springs 25 are shown connected to the top cover 30 and the coupling member 20, while the cover 80 and trough 5G form the box of the ski braking system.

As shown in FIG. 1, the four corners of the substantially rectangular frame 2750 are formed of reinforcements made of, for example, solid material. In these corners, horizontal elongated holes 51 are formed, which extend into the side wall 5 in the direction of the longitudinal axis of the braking device of the ski.
5 extends to form a support for the brake arm 10.

Furthermore, a groove or recess 52 is formed laterally within the elongated hole 51. and receives annular collars or rings 7 provided at the front and rear of the brake arm 10 so that the brake arm is supported for rotation but not for displacement within the trough 50. Fixed.

Furthermore, as shown in FIG. 1, the bottom wall of the trough 50 is provided with holes 53 for the tightening bolts 35. The holes can be threaded holes or threaded sleeves that serve to guide and retain the tightening bolts 35.

As can be seen from FIG. 1 and FIGS. 6 to 8, the connecting member 20 for the two brake teams 1O is essentially U-shaped in cross section, and its two legs 21 are , at their ends are used to support the brake team IO for rotation as explained in detail below. Although a spring 25 is shown below the coupling member 20, the spring can be implemented as a coil spring or a leaf spring. The seat 26 for the spring 25 is the trough 5
It is located almost at the center of 0. The seat is an outer ring extending along the outer portion of the spring 25 or
The central projection on the bottom wall of the trough 50 extends into the interior of the spring and determines the center of the spring. Instead,
Alternatively, additionally, a seat for the spring 25 can be provided on the underside of the coupling member 20 to engage with the spring 25 in the assembled state.

As shown in FIGS. 1 to 5, the brake arm IO is designed as a crankshaft with a straight section to serve as a longitudinal axis 15', around which the brake arm IO rotates. It is possible. In these straight sections, two annular collars or flanges I3 are shown respectively, which fit into grooves 52 in the trough 50.

The crank or crank arm 11 has a foot between these straight parts, and an end 2 of the leg 21 of the connecting member 20.
2 is engaged with these crank arms. The brake vanes 12 of the rear part of the brake arm 10 are each connected with a transition section 14 to the rear part of the brake arm lO, which constitutes a longitudinal axis 15 . (See FIGS. 4 and 5.) The box cover 80 is a box-like structure similar to the bottom 117500 cover and includes eight side walls.

Two elongated holes 86 are formed in the front and rear end walls, respectively, aligned with the elongated holes 51 of 7750, and their inner ends receive the longitudinal shaft 15 of the brake arm 10 (7). At the same time, cover so#-1t.

When assembled, the brake arm IO, which is fixed in the horizontally elongated hole 5 only in the vertical direction and the front and back, is prevented from being taken out laterally or falling down.

1, 9 and 10, the opening 34 is located at the top 32Vc of the cover 30 and receives the tightening bolts 35. These tightening bolts are connected to the trough 50 and the cover. 30 and serves to secure the ski braking device to the ski.

In FIGS. 2-5, the heel portion of the ski locking device is designated generally by the reference numeral 10. In FIGS. Reference number 11 is
The ski is shown in its entirety, with 12 indicating the upper surface. ski 7
The lateral edges of 1 are designated by 13 and the longitudinal axis by 75.

The ski braking device can be easily attached by making holes in the ski 71 by applying gauges to the holes 58 in the trough 50. To assemble the autonomous braking device for skis, first, install spring 2.
5 is placed on the seventh seat 26, and the connecting member 20 having the crank arm 1 rotatably supported by the brake arm i0 is placed on the spring 25, and the longitudinal axis 15 is placed on the trough 50.
Note that the ring 7 is inserted into the oblong hole 5, and that the flange 13 of the ring 7 is fitted into the groove 52. Next 1
Place the cover 30 on top of the above assembled object and cover 8.
The side wall 31 of 0 is made to straddle the side wall 55 of the trough 50 and is slid along it. Since the recess or vertical hole 86 receives the longitudinal axis 15 of the brake arm IO, it prevents the brake arm 10 from being pulled out to 144 and allows the lever 7-AIO to be freely rotated around the longitudinal axis 15. This makes it possible for people to rotate. The cover 30 is fixed to the trough 50 with tightening bolts 35. To this end, a tightening bolt is inserted into the opening 34 and screwed into the respective thread of the threaded hole 53 (see FIG. 10).

As best shown in FIGS. 9 and io, which show the longitudinal portion of the cover 80, the cross-sectional shape of the cover is formed by a recess 89 defining the aperture 34 and, in the lower region, by the respective tightening bolt. 35 is substantially limited by a longitudinal flank plate 33 having a passage opening 38 for 35 . Further, the belly plate 88 limits the space between the belly plates, receives the screw elastic connecting member 20, and constitutes a seat thereof.

Further, as shown in FIG. 10, the outer belly plate 33t of the recess 39
'i, their lateral ventral plates have a minimum clearance of trough 50 iam
55 is spaced apart from the outer wall 31. The cross-sectional shape of the cover 30 increases, on the one hand, the stiffness of the cover 80 and, on the other hand, when the braking device of the ski is moved from its braking position to its braking position and from its braking position to its braking position, Plate 38 and sidewall 81 provide a guiding mechanism for vertical movement of cover 30 with respect to trough 50.

As can be seen from FIGS. 9 and 10, on the one hand, the passage opening 38 guides the shaft of the tightening bolt 85, and on the other hand, the tightening bolt 350 head is guided by the belly plate 33 of the recess 39. At the same time, the abdominal plate 38 and the side wall 81 are connected to the side wall 5 of the trough 50.
5, so the components cannot tilt towards each other/Ii.

Next, the function of the ski braking device of the present invention will be explained in detail with reference to FIGS. 6 to 8. FIG. 6 is a cross-sectional view of the ski braking device showing the braking ready position, FIG. 8 showing the braking position, and FIG. 7 showing the intermediate position between these final positions of the brake vanes of the ski braking device. shows. It is clear that the brake arm 10 is pivotable together with the crank arm II and the brake vane 12 between a braking ready position and a braking position about a longitudinal axis 15, which longitudinal axis 15 is shown in FIGS. As best shown, it extends parallel to the longitudinal axis 15 of the ski 71. The pivoting movement of the brake arm lO is carried out by a spring-elastic coupling member 20, which is made of spring steel, which engages the crank arm 11 of the brake arm lO by means of the ends 22 of the two legs 21. It is convenient. For clarity of illustration, cover 30 is not shown in FIGS. 6-8.

In the arrangement shown in FIG. 8, spring 25d is shown in seat 26 in a relaxed state. That is, since the spring elastic connecting member 20Fi to the top 28 with which the spring 25 is in contact is located at its upper position and is raised along the upper side by the crank arm llIr1 and the end 22 of the foot 21,
The brake vanes 12 are shown tilted downwards, which means that the braking device of the ski is in the braking position.

As shown in FIG. 7, when the spring-elastic coupling member 20 is pressed down together with the cover 30, which is not shown in this figure, the spring 25 is compressed. The legs 21 of the connecting member 20 yield inwardly and the upper portions of the apex 23 yield outwardly, while 422 of the connecting member 20
The brake 10 is rotated around the longitudinal axis 15 by.

Figure 6 shows the end positions of the and Q movements. brake blade 1
2 faces upward, the crank arm 11 is in a downward position contrary to the arrangement shown in FIG. 8, and the spring 25 is compressed between the connecting member 20 and the bottom of the trough 50. . In this position, the side wall 3r of the cover 30 rests on the top of the ski.

The brake vanes 12 formed at the end of the brake arm 10 are arranged laterally with respect to the longitudinal axis 15 of the brake arm 10 in the braking ready position as shown in FIG. 4 and in the braking position as shown in FIG. It's biased toward In the inactive position, the brake vane 12 can be positioned against the heel portion of the ski locking device.

Further, as shown in FIG. 8, in the braking position, the brake blades 12 of the brake arm 10 extend laterally at an oblique angle beyond the ski side edge 73, so that when the braking position is in the braking position, the brake blades 12 of the brake arm 10 extend laterally at an oblique angle. Scratches are prevented not only on the surface but also on the side edges. The brake blade 102 of the brake arm lO is
It is possible to pivot from the braking position according to FIG. 8 to the braking ready position shown in FIG.
The brake vanes 12 are offset inwardly not only with respect to the side edges 13 of the ski 71 but also with respect to the longitudinal axis 15.

From Figures 6 and 8, the frame arm iris 0 is the longitudinal axis 1.
An angle of less than -180' around 5, e.g. about 160
It will be seen that it can be rotated by .

However, this is for various reasons. On the other hand, this ensures that in the braking position the brake vanes 12 extend obliquely from the ski.

ing. On the other hand, the crank arm 1 of the brake arm 10
1 also performs angular movement at an angle of 180° or less.

That is, if no other forced guidance device is provided on the crank arm, the crank arm will not reach the positions of top dead center and bottom dead center, which are unstable positions that impair the operation of the braking device of the ski.

The movement of brake arm 10 can be limited in various ways. On the one hand, a stop device can be provided on both shoulders,
These stopping devices can be embodied by the heel part 10 and the side edge 73 of the locking device of the ski 71. On the other hand, a separate stop device can be provided on the brake arm 10. Also, this movement is controlled by the connecting member 20
It can also be limited by the travel that can be performed in the space between 0 and the bottom trough 50. This process is performed by tightening the tightening bolt 3 as shown in Fig. 9 and Fig. 1θ, for example.
It can be adjusted by 5. Relaxed position of the ski brake (
In the braking position), the head of the tightening bolt 35 is in the recess 39
In this way, the tightening bolt 3
5 limits upward movement when screwed into the corresponding screw in hole 53. Furthermore, the travel of coupling member 200 downwardly within cover 30 is limited by the height of sidewall 31 of cover 30 or the height of sidewall 55 of trough 50 (see FIG. 10).

From FIG. 6 and FIG. 8, the following and. That is, the width of the top 23 of the connecting member 200 between the two legs 21 is narrower than the space between the longitudinal axes 15 of the two brake arms 10, and the reason for this is that the top dead center position of the crank arm IIH is This is because it is easily prevented from being taken. If pressure is applied to the connecting member 20 from the top via the cover 30 starting from the relaxed position (braking position), the position shown in FIG. 7 is automatically passed through. That is, the crank arm 1 draws an arcuate shape, and the arcuate shape moves in the direction of the spring 25, in other words, toward the inside of the space within the box. For this purpose, the coupling member 20 is a spring-elastic member, the legs of which are pushed elastically inwards against the underside of the coupling member, while the top 23 is pushed downwards from a horizontal position in the area of its corners. You can surrender. As previously mentioned, the top 8 of the cover 30
2 is formed with an inclined surface extending flat from the top to the side wall 31, thereby providing a roof-like structure of the cup (-80) (see FIGS. 1, 9 and 10). ).When the ski locking device is stepped on, the sloped top 82 of the pad facilitates the lowering of the cover 30 and the connecting member 20, and the aforementioned rotational movement of the brake arm around the long axis 15 is facilitated. To begin with, the longitudinal axis 15 extends parallel to the longitudinal axis of the ski 71.

As shown most clearly in FIGS. 4 and 5, the longitudinal axis 15
The lateral offset of the brake vane 12 in relation to the brake blade 12 is effected by the transition section 14 of the brake arm 10. It is convenient to provide these transition sections 14 so that they extend in a plane perpendicular to the plane defined by the longitudinal axis 15 of the crank arm 11 designed as a crankshaft and of the brake arm IO. In the arrangement shown in FIG. 4, the crank arm 11 projects downwards with respect to the plane of the drawing (see FIG. 2), while in the arrangement according to FIG. 5, the crank arm 11 projects upwards with respect to the drawing (see FIG. (See Figure 3).

Unfortunately, regarding Figures 4 and 5, we must point out the following. That is, the longitudinal axis of the brake arm lO can pass under the sole retaining element of the heel portion 70 of the ski locking device easily and without contact, as shown in FIGS. 2 and 3. In addition, it can be placed close to the upper surface of ski 71.

It is convenient to use spring steel as the material for the spring-resilient coupling member 20, while plastic and/or metal are suitable materials for the bottom trough 50 and top cover 30 depending on the stiffness and weight requirements. It is. Spring 2
To what extent does the elastic energy of 5 cause the spring 25 to push the connecting member 20?

As a result, it is determined whether the cover 80 should be oriented upward.

In order to guarantee an outward pivoting of the brake vane 12 without applying any force to the brake vane [2 in the braking position and an opportunity to hold the brake vane 12 and push the brake arm lO upwardly away, a strong spring 25 is applied. Usable. A high spring rate of the spring 25 does not adversely affect the functioning of the ski braking system. The reason is,
Spring 25 is activated when the user enters the ski locking device and spring 2
5 is compressed by the user's entire weight when pushed downward through the cover 80 and the connecting member 20 in contact with the cover. Only the user's weight sets the upper limit for the spring rate.

A sealing mechanism may be provided between the bottom trough 50 and the top cover 80 to prevent dust and snow from entering the box. For example, a sealing ring may be provided, or the side wall 81 of the top cover 30 may be made of rubber or flexible plastic and may be of bellows construction or shape to resiliently connect to the bottom trough 50 and/or the ski. This is what is being done. The zigzag structure of the bellows can move vertically along the side wall 55 of the bottom trough 50 to ensure the desired seal.
