Definitions

• the application relates to a heel holding device for cross-country and touring ski shoes, as is known for example from DE 34 37143 C1.
• the heel holding device described in DE 34 37 143 C 1 offers the cross-country skier the desired hold on the cross-country skis in normal weather in difficult terrain in order to be able to carry out desired changes in direction, such as plow arches, side slides and similar maneuvers. If there is a corresponding lateral or vertical overload, the heel holding device releases the shoe. With temperature fluctuations that go into the plus and minus degrees, the binding tends to freeze due to its complicated structure. The safety function of the heel holding device is partially overridden.
• the task of the new development is a heel holding device which has the advantages of that described in DE 34 37 143 C 1, the disadvantages of which are eliminated by new construction and appropriate choice of material. Another goal was to reduce the number of individual parts required to manufacture the heel holder at a lower price.
• the heel holding device described in DE 34 37 143 C 1 tends to freeze very strongly. This applies particularly to the coil spring of the holding part as well as the compression spring and the snap lock. In order to avoid such difficulties, springs were completely dispensed with in the new development. This task was solved as follows.
• the heel holding device consists essentially of
• a holding device for the shoe end consisting of a base plate with adjustable clamping device, a holding element for the sole protrusion on the shoe and a spring clip or a rocker, as well as a rotatable, resilient or spring-loaded plate with a wedge or cone, which lies in the middle Shoe sole recess engages.
• the required spring functions of the heel holder and the pressurization of the turntable are directly taken over by the heel holding device through a suitable material selection and appropriate shaping.
• the rotating plate is spring-loaded by a resilient housing extension, the hardness of which is adjustable by a device.
• the upper part of the heel holding device designed as a pre-bent spring, takes over the retrieval of the holding element in the unlocked position (Fig. 1).
• the heel part of the shoe can be moved freely in the sighting necessary for cross-country skiing.
• pressure is applied to the spring clip by the ski pole or by the second ski, the latter deforms into an extended position and engages in an intended clamping device.
• the holding element is pushed towards the end of the sole. It locks the sole end of the shoe ( Figure 2).
• the holding element presses in the direction of the ski end onto the spring clip which is under tension.
• a predetermined value which can be set with an adjusting device
• the spring clip is released from the holding element when the pressure is applied to the ski surface the clamping device pressed.
• the holding element tilts away towards the end of the ski, thus releasing the shoe.
• the release value of the heel-holding device is set in such a way that turns and arches can also be made at any time during sliding phases of the runner.
• the set trigger value is opened with the shoe.
• the spring clip jumps out of the clamping device and pulls the holding element towards the end of the ski. After the gliding phase, the skier can switch to the normal running style without further actuation of the heel stop.
• the old alternative proposal c) is structured similarly to that described in proposal b).
• the difference to b) is that the bracket is designed as a seesaw.
• the binding is locked by pressurizing the bracket in front of the axis point (towards the ski tip).
• the binding is unlocked by pressurizing the bracket behind the pressure point (towards the end of the ski). All other functions are already described in point b).
• the heel holding device with a rotatable plate and wedge for the shoe sole recess is mounted on the ski in such a way that the holding bracket (5) in the rest position does not hinder the sole extension designed as a wedge. A normal running movement is guaranteed.
• the cross-country skier can now fix the shoe firmly on the ski in the heel area by pressing the upper part of the housing (2). This fixation turns the LL binding into a light alpine binding, which releases the shoe when the set release value is exceeded laterally or vertically.
• the retaining bracket (5) returns to its rest position by lifting the heel. The same process can also be achieved by pressing the unlocking wedge (10).

• FIG. 2 heel holding device, side view in the locked state
• FIG. 4 heel holding device, sectional drawing in the locked state
• FIG. 6 heel-holding device, rotating plate, cross-section spring-loaded with an icing-free snap lock
