The invention relates to an adjustable lever lock for ski boots, at which is a pivoted clamping lever mounted on one shaft part via a hinged clamping bracket interacts with a hooking part mounted on the other shaft part.

There are different versions of adjustable lever locks for ski boots known. In the case of such a closure, one end of the clamping bracket is on a shaft part attached, while its other end in on the clamping lever attached to the other shaft part at a distance mutually arranged locking hooks can be suspended. Another lock design is for Attaching the bracket connected to the tensioning lever or hinged to it on the other shaft part than the tensioning lever attached, having spaced apart latching hooks Plate provided.

The aforementioned closure designs have the disadvantage that with them only one relatively rough or gradual width adjustment is possible. This may not be the case for good in every case and secure ski guidance, the required firm fit of the shoe on the foot can be guaranteed.

It is also known a width-adjustable clamping lever lock, in which the bracket with its one end is hinged back to the tensioning lever, while its other end with an adjusting screw is connected, which is screwed into a thread provided at the relevant end of the bracket. At its end facing away from the bracket, the adjusting screw has a head that is inserted into one of the other Closing flap provided as the clamping lever or the like. Can be suspended. With this type of lock an almost infinitely variable width adjustment is possible by moving the screw more or less far is screwed into the thread provided on the bracket. Such an adjustment will, however hindered or even made impossible by icing of the closure. This disadvantage does not apply This is important because the skier generally has an adjustment between ascent and descent want to make the closure. During the ascent, the shoe should only be loosely closed to protect the Not to inhibit blood circulation, while the shoe should be very tightly closed on the descent to ensure a tight fit on the foot.

The invention is based on the object of creating a width-adjustable clamping lever lock for ski boots which, with the same adjustment option as the last-mentioned be-width adjustable clamping lever lock for
Ski boots

Applicant:

Rieker & Co., Tuttlingen (Württ.)

ίο knew lock design with an adjusting screw does not have the disadvantage of this closure. This object is achieved according to the invention in that the tensioning lever with the tensioning bracket via an adjustable width articulated in the tensioning lever Screw adjustment is connected and that the clamping bracket optionally in the several at a distance arranged latching hooks having hooking part can be suspended. Clamping lever and hooking part are included arranged on different shaft parts. The noticeable

ao times the closure according to the invention are known per se. But their union leads to one wide adjustable ski boot closure, which has a greater adjustability than the known Tension lever locks, in which the tension bracket can be optionally placed in one of the spaced apart Notches can be hung. By icing over the adjustable screw adjustment the practical value of the closure according to the invention is not impaired, as can be seen from the following still described in detail handling of the closure results, with reference to the drawing Is referred to. In this shows

F i g. 1 is a perspective view of a ski boot which is equipped with the tension lever locks according to the invention is equipped

F i g. 2 shows a diagrammatic representation of the individual parts of the lock, the tensioning lever being in FIG is in the open position,

F i g. 3 is a plan view of another embodiment of the lock in the closed position, FIG. 4 shows a one-piece design of the clamping bracket.

In the case of the one shown in FIG. 1 shown ski boots are arranged along the back of the foot three tension lever closures. The clamping levers 3 and their bearing plates 4 are on the outside of the shoe lying a shaft part 1 and the bearing plate of the hooking part 15 attached to the other shaft part 2. The tensioning lever 3 is rotatably attached to its bearing plate 4. The bearing plate 4 consists of a essentially flat plate 5, on the upper side of which there are two spaced-apart bearing

attachmentsö are attached, to which by means of a Pin 7, the spaced apart web parts 8, 9 of the clamping lever 3 are mounted. Of the Clamping lever 3 is accordingly mounted so as to be pivotable about pin 7 by approximately 180 °.

In the web parts 8, 9 of the clamping lever 3, a joint 10 is mounted, which - from the drawing unrecognizable - has internal thread which receives the adjusting screw 11.

The adjusting screw 11 is connected to a clamping bracket 13 which is in one of the latching hooks 14 of the total with 15 designated hooking part can be hung.

The bearing plate 4 and the hooking part 15 are provided with bores 16 and 17, respectively, through which rivets for fastening the closure parts on the shaft parts 1, 2 can be pushed through. '. ".

In the case of the FIGS. 2 and 3 shown embodiments the clamping bracket 11, 13 consists of two parts which are hingedly connected to one another. to For this purpose, the adjusting screw 11 has a shoulder 11 'to which the clamping bracket 13 is articulated. Due to the articulated connection of the two. Parts of the clamp can be in the closed position adapt particularly well to the instep. The bracket 13 can, however, also be made of wire with great inherent rigidity be formed from a flexible cable.

In the case of the one shown in FIG. 4, the clamping bracket 13 is integral with the adjusting screw 11 formed.

"During use, a rough adjustment of the lock is first made by using the clamping bracket 13 is hooked into one of the locking hooks 14, which is considered for the tightest position to be set comes. After the skier has determined whether the lock is too tight or too tight in this position is loose, the adjusting screw 11 is correspondingly far out of the thread after lifting the clamping bracket 13 of the joint 10 out or screwed into this. This enables an almost infinitely variable fine adjustment of the Closure achieved and the tension desired for the tight fit of the shaft parts on the foot Fastener set. This tight setting is generally only used for descent. If, after this, a looser setting is desired, only the clamping lever 3 needs to be pulled up and the

ίο Clamping bracket 13 hooked into the next locking hook 14 to become. By icing up the adjusting screw 11, the transition from the tight to a looser lock setting is not hindered.
