Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved braking mechanism for skis with braking spurs movable from a raised ski position to a lowered braking position. Such ski braking mechanisms are designed to prevent the ski from moving down the slope when the ski is removed from the skier's boot. The improvement is that when the braking spar is in the lower braking position,
The aim is to use a separate brake spar with a stop device to prevent the brake spar from moving towards the mid-length of the ski. Furthermore, the construction of the brake mechanism and the independent features of the brake spars allow each brake spar to be retracted toward the intermediate longitudinal portion of the ski when the brake spars are in the raised ski position.

Typically, ski braking mechanisms include braking spurs attached to a common braking unit. Braking units often have braking spurs at each end.
The middle part of the U-shaped rod is attached to the brake pedal. A pivot axis of the arm extends along the intermediate portion of the U-rod between each brake spar and the brake pedal, by means of which the brake unit can perform a pivoting movement. When the ski is removed from the skier's boot, the brake pedal is biased upwardly by a spring mechanism. This upward movement of the brake pedal causes the brake spar to undergo a pivoting movement from the raised ski position to the lowered brake position. In the down braking position, the braking spar prevents the ski from moving down the slope, thus eliminating the need to use an ankle safety harness. The dangers of such safety belts are well known.

The braking mechanism described above has drawbacks. When the brake spar is in the raised ski position, the brake spar extends laterally from the ski and is generally parallel to the edge of the ski. Although this lateral extension is generally only slight, contact occurs between the braking spar and the snow even when the spar is in the upski position. Particularly when skiing is done in deep snow or when the ski is not flat against the snow, the additional resistance created by the braking spurs compromises the performance of the ski somewhat. Moreover, the contact causes unnecessary wear on the brake spars.

Independently operating brake spurs are known and these also have several drawbacks. While in the down braking position, the braking spar has a tendency to move towards the mid-length portion of the ski. As a result, the effectiveness of the brake spar is compromised. Generally, brake spars consist of a metal rod with an injection molded plastic ski cap, preferably at the end. The lower end of the spark cap is often hook-shaped. The inward movement of the braking spar causes the hook-shaped spur cap to catch on the lower longitudinal edge of the ski during braking.
Skis can bend from the most effective position for braking.

The present invention overcomes the other binding drawbacks mentioned above. A preferred form of the invention includes a pair of independently movable Z-shaped rods, each rod having an outer leg forming a brake spar and an inner leg attached to the brake pedal. , and a central transverse bar forming a pivot axis. When the brake spars are in the raised ski position, each brake spar can be retracted towards the mid-length portion of the ski by independent movement of the brake units.
In this way, the brake spar does not impede ski movement and wear on the brake spar is minimized.

Additionally, the preferred embodiment of the invention includes a stop to prevent inward movement of the brake spar while the brake spar is in the lowered position. The stop does not prevent inward movement of the brake spar when it is in the raised position. The stop may be formed in the cover plate of the bearing housing and may include a flange designed to prevent lateral movement of the Z-shaped brake rod when the brake spar is in the lower brake position.

The structure of this braking mechanism is simple, and the braking mechanism can be manufactured at low cost.

FIG. 1 shows a plan view of a braking mechanism according to the invention. The upper half of FIG. 1 shows the braking mechanism in the up ski position, and the lower half shows the braking mechanism in the down braking position. The detailed description below uses two Z-shaped rods, one on each side of the ski, and two braking spurs.

The braking mechanism has a base plate 1 which is fixed to the ski 3 by screws 2. In FIG. 1, the entire board is not shown, but only the left half of the board. The right half of the board includes a support bar, a guide bar, and a ski sole holder, which are not an aspect of the invention. The braking mechanism has two braking spars 4, 5, which are the outer legs of two Z-shaped rods. Furthermore, the rod includes a pair of inner legs 8, 9 whose ends are bent towards each other and which are braked so as to allow a pivoting movement of the bent ends. It is attached to the pedal 16. The ends of the inner legs 8, 9 may be flexibly connected if they are bent towards each other.

Base plate 1 and cover plate 10 form a bearing housing. In this bearing housing, the lateral parts of the Z-shaped rods form pivot axes 6,7. These pivot axes 6,7 are held between pairs of rivets 11 which prevent the pivot axes 6,7 from moving along the length of the ski 3. Rivets 11 stand perpendicular to the surface of the ski. The upper end of each rivet 11 is attached to the cover plate 10,
The lower end is attached to the substrate 1. The cover plate 10 is provided with a flange 12 forming a stop according to the invention. When the brake spars 4, 5 are in the raised position and the inner legs 8, 9 are in the lower position on the top of the ski 3, the flange 12 is attached to the spar 4, as shown in the upper half of FIG. , 5 towards the longitudinally intermediate portion of the ski.
However, when the brake spars 4, 5 are in the lower braking position and the inner legs 8, 9 together with the brake pedal 16 are in the raised position, as shown in the lower half of FIG. This prevents the inward movement of the shafts 6, 7 and thus the inward movement of the brake spars 4,5.

Cover plate 10 has slots 13 separating flanges 12. The slot 13 is designed to allow a coupling member 17, which is rotatably attached to the base plate 1 at one end and attached to the brake pedal 16 at the other end, to pass therethrough. When the brake spars 4, 5 are in the raised ski position, the joint members are approximately parallel to the surface of the ski 3. A spring 18 is attached to the base plate 1 and positioned perpendicular to the length of the ski 3 and parallel to the surface of the ski 3. When the skier's boot is removed from the skis 3, the spring 18 biases the coupling member 17 and thus the brake pedal 16 upwards. The inner legs 8, 9 attached to the brake pedal 16 are also biased upwards, resulting in a pivoting movement of the brake spars 4, 5 to the lower braking position.

Devices are provided for biasing the inner legs 8, 9 to move the brake spurs 4, 5 towards the mid-length of the ski when the brake spurs 4,5 are in the raised ski position. ing. This biasing device is a guide bar 19, 20 attached to the bottom of the brake pedal 16. Guide bar 19, 20
simply engage the inner legs 8,9 when the brake spurs 4,5 are in the lower brake position.

Spark caps 14 and 15 are brake spurs 4 and 5
is attached to the free end of the braking spar 4, 5 to increase the braking surface of the braking spar 4, 5. These ski caps 14, 15 are preferably injection molded plastic, but may be of other suitable materials. Spark cap 1
The lower part of the end of brake spar 4, 5
When in the downward braking position, it is approximately hook-shaped to further prolong the braking effect.

The stop can also be integrated into a guide track running towards the mid-length of the ski. The guide tracks enable a smooth transition of the braking spurs 4, 5 from the raised ski position to the lowered braking position when the ski is removed from the skier's boot.

Although the invention has been described in detail with particular emphasis on preferred embodiments, it is to be understood that variations and modifications may be practiced within the scope and spirit of the invention.
