Description

Quick-release fastener for skis and mountaineering boots

The invention relates to a buckle fastener for ski and Mountain boots, consisting of a tension bracket that works together with a toothed tensioning lever and that is attached to one for attachment serving holding plate is mounted pivotably about a horizontal axis 1st. With known buckles this Art If the tension bracket is fixed, i.e. not detachable from the retaining plate tied together. This has the significant disadvantage that when a Breakage or damage to the entire pulling bow The tension bracket and the retaining plate would have to be removed from the shoe and replaced by a new one. Around the retaining plate To detach them from the shoe, the fastening rivets had to be removed with a drill. To fix the new, A riveting machine is again required, which consists of a unit consisting of a tension bracket and a retaining plate. The previous design has so the disadvantage that it is difficult, time-consuming and with special machines to replace a pulling bracket and holding

1st possible disk, and also that the total _# of tension clamp and support plate existing unit had to be replaced with a new one in case of breakage or damage einee ZugbUgels.

In order to eliminate this disadvantage, is according to the invention The ring-shaped tension bracket is pivotably arranged in a bearing part and this is detachably connected to the retaining plate, expediently with a flat head screw. This new type has the advantage that the user of the ski or mountaineering shoe can use it himself and with a few simple steps Using special tools, the broken or damaged drawbar is replaced or replaced by a new drawbar can be.

The invention is described below with reference to an in the drawing advantageous embodiment example shown in more detail explained.

The buckle connection shown consists essentially from a toothed clamping lever 5 pivoted about the axis 2 in a bearing block 1 and one in the tooth gaps this clamping lever attachable tension bracket 5, which is attached to a Attachment to the holding plate 7 serving to the shaft part 6 is mounted pivotably about a horizontal axis 8. The bearing block 1 of the clamping lever is attached to the other shaft part Io of the shoe with a retaining plate 9.

As can be seen from the drawing, the ring-shaped tension bracket 5 is pivotably arranged in a bearing part 11 which, in the exemplary embodiment shown, is detachably connected to the holding plate 7 by means of a flat head screw 12. In the particularly advantageous embodiment shown, the holding plate 7 has a vertical cylindrical socket 14 provided with an internal thread 13, which serves both for pivoting the bearing part II about a vertical axis 13 and for screwing in the flat head screw 12. The bearing part 11 is advantageously bent from a piece of sheet metal which .nit the approximately cylindrical part 11 a forms the pivot bearing for the part 5 a of the tension yoke, and is mounted pivotably around the Stutj-fo.J.4 with the tabs 11 b. This new design has the advantage that the forces exerted by the tension bracket 5 are absorbed by the connector 14 of the holding plate, so that the screw 12 is not touched. In addition, this design has the advantage that the tension bracket 5 is not only around the * _n

horizontal axis 8 "but also around the vertical" Axis 15 is pivotable »so that the handling of the pull bow when closing the lock with the tensioning lever 15 is facilitated.

It is also advantageous to provide a semi-circular bead 16 in the shape of a semi-circle, "which partially surrounds the bearing part 11 1" and which has the edges 17 "1". Forms stops to limit the pivoting movement of the bracket 5. When pivoting in the direction A about the axis 15 or the connecting piece 14, the latter can only move in a smaller angular range until the bearing part 11a touches the stops 17, 18. The bead 1 € can optionally be formed by corresponding deformation of the holding plate 7 made of sheet metal. In the simple, sloped design, this cover plate 19 has outlet nozzles 2o which are plugged in from above through correspondingly large holes 21 in the holding plate 7 and then according to Pig. 3 are riveted »so that a firm and permanent connection between the two plates 7 and 19 is created. These outlet nozzles 2o not only serve to establish this connection »but at the same time also allow the fastening rivets 22 to pass through the holes 23 of these outlet nozzles *

The tension bracket 5 can be made from a simple bent wire consist of annular stirrups. In the advantageous embodiment shown, however, the tension bracket 5 is designed as a spring clip. For this purpose part 5 a of the tension bracket 3 with telescope tubes 5 b firmly connected. In which helical compression springs are arranged, which are on the ends of the bracket part 5 c and are supported on the free ends of the tubes 5 b If the bracket 5 is subjected to an oblique load, the U-clamp part 5 c move in pulling direction B against spring force * The only advantage of this is that the clamping lever is closed 3 is facilitated, but also that there is less stress on the holding plate or the connection piece 14.

In the embodiment shown in Fig. 1 is advantageous Bearing block 1 arranged on a base plate 1 a, which is detachably connected to the holding plate 9, so that even with a Breakage of the clamping lever of the bearing block 1 can be replaced quickly and easily.
