DE1075014B - Closure for ski boots - Google Patents

Description

The present invention relates to a ski boot closure with a clamping lever and overlapping Closing flap.

When ascending on skis, the ski boots should only be loosely closed so that the blood circulation in the Foot is not inhibited. When the ski boots are tightly on, the feet cool down and become significantly tired faster than with a relatively loosely closed shoe. On the other hand, for the descent it is necessary that the shoe fits like a glove on the foot and gives it a secure hold. But now it is often not possible to close the shoe tighter before departure, because in some cases the laces freeze and the Fingers are stiff from the cold. If you are still standing on the slope, then such work is completely impossible.

Shoe fasteners are known in which a cord is tensioned by means of a tension lever. Here, however, the clamping elements are arranged on the edge of the closing flap so that they are closed when they are closed cannot overlap each other. In addition, the locking lever holders are designed so that they are pulled together tip and prevent the locking tabs from sliding on the tongue. You would this use known shoe fasteners on ski boots, then the locking lever holders were among the enormous Press the necessary tensile forces on the instep of the foot accordingly. Such a closure is probably for ordinary people Walking boots, but not suitable for ski boots.

There are also shoe closures with overlapping closing flaps, in which several clamping levers are attached to a closing flap, became known, in which the closing flap when closing the clamping lever can be pulled together more or less strongly. The clamping lever bearings have these Versions have contact surfaces that cause pressure after the shoe fastener is closed due to the tilting moment, exert on the instep. But this also means that these shoe closures are for Ski boots not suitable.

The present invention now aims to create a clamping lock of the type mentioned especially for ski boots, which avoids the disadvantages mentioned and allows opening and closing and adjustment of the closure tension with a minimum of manipulations.

The ski boot according to the invention, in conclusion, of which Shaft along the instep has overlapping closing flaps, in which on the one Closing flap several pulling members and arranged on the other closing flap corresponding clamping levers are, wherein each clamping lever bearing has a support plate rigidly connected to it, is characterized

in that the length of the support plate in the direction towards the edge of the closing flap at least that Is three times the height distance between the support plate and the clamping lever pivot axis.

With this design, the tilting moment is absorbed by the contact plate when the closure is tensioned and distributed over a relatively large contact surface. This reduces the pressure on the Foot reduced to a bearable level even with the toughest tension, and the edges of the closing flap can move on the tongue towards each other.

The drawing shows an example of an embodiment of the subject matter of the invention, namely shows

2 shows the clamping lever with its holder in a side view,

Fig. 3 is a plan view according to Fig. 2,

4 shows a clamping lever holder attached to the shoe without a support plate, partially in section, and

5 shows a clamping lever holder with a support plate attached to the shoe, partly in section.

Fig. 1 shows a ski boot closure, in which the closure flap 6 of the shoe six eyelets 1 and on other closing flap 3 three clamping lever bearings 4 are attached. The corresponding pulling element is in one the clamping lever bearing closest to the latch 5 & of the respective clamping lever 5 is attached so that the When the clamping lever 5 is closed, the shoe rests as comfortably as possible on the foot for walking and climbing. Before the

Claims (3)

Departure the clamping levers 5 are opened and the tension members 2 are hung in a detent 5 δ further away from the center of the shoe, so that after closing the three clamping levers 5 the shoe rests firmly against the foot, as is necessary for a descent. After the descent, the shoe can be relaxed again in a few simple steps in order to give the blood in the foot the possibility of circulation. In FIG. 4, the clamping lever bearing 4 is riveted onto the overlapping part 3 without a support plate. By pulling the pulling members 2, the clamping lever bearings 4 are pulled into the dot-dash position, so that the overlapping part 3 is pressed into the foot. This part compresses and forms a bead which abuts the end of the inner lower lobe 6 of the shoe, whereby the two lobes are prevented from sliding over one another. In addition, there is pressure on the foot that is unbearable for the skier. In order to avoid this, in the embodiment of the invention shown in FIGS. 1, 2, 3 and 5, a rigid bearing foot 4 a, designed as a support plate on the closing flap 3, is attached to the clamping lever bearing 4, which extends over the instep of the shoe . When the shoe is closed, the flap part 3 is supported on the flap 6 without bulging as a result of its connection with the bearing foot 4 a, so that the two can easily slide over one another. By pulling in the direction of the arrow ζ, the pressure on the instep generated by the tilting moment is supported by a pressure on the instep of the foot that is reduced in relation to the lever arm and therefore does not have a disruptive effect. The length of the bearing foot in the direction towards the edge of the closing flap 3 is a multiple of the distance formed between the support surface and the clamping lever axis of rotation 5 a. As traction organs, in addition to laces made of leather or plastic z. B. wire cables, cords, etc. can be used. Patent α. \\ s ν n ü che: 1. Closure for ski boots, the shaft of which has overlapping closing flaps along the instep, in which on the one closing flap a plurality of tension members and corresponding clamping levers are arranged on the other closing flap, each clamping lever bearing having a support plate rigidly connected to it, characterized in that the The length of the support plate (4 a) in the direction towards the edge of the closing flap (3) is at least three times the height distance Qi) between the support plate (4a) and the clamping lever pivot axis (5 α). 2. Closure for ski boots according to claim 1, characterized in that the clamping lever bearing (4) with the support plate (4a) is arranged on the closing flap (3) in such a way that the plate (4a) rests on the instep of the foot when the lock is closed. 3. Closure for ski boots according to claims 1 and 2, characterized in that the clamping lever (5) is toothed and thus has a number of hooking points (5 b) for the pulling element (2).
