Abstract

Binding opener for safety bindings (8) on sliding or rolling surfaces (6), preferably skis and snowboards, developed for manual operation suitable for the fact that a safety binding (8) can be opened by the driver himself even in tricky situations, characterized in that at least one a fixed connection between at least one torsion spring (2), which is placed above the rear binding head (8) and is attached to the sliding surface (ski) or rolling surface (6) or the permanently mounted accessory, connecting part (1) of a certain length and the sliding or rolling surface (6) produces.

Description

Safety bindings for sliding and skateboards, preferably for skis, snowboards, etc., are very difficult to open in certain body positions of the user, as to trigger the opening strong pressure must be exercised. When the user (skier) is standing, the opening of the binding is hardly a problem because he can use his body weight with the help of a (ski) stick on the opening mechanism of the binding. However, if he is in a lying, sitting or other, complicated position, from which he can not get rid of and in which it is not or only partially possible to use the body weight, opening the binding is very difficult, sometimes even impossible. It then needs help from others, but often does not arrive or only after some time. These situations occur again and again. For example, after falls in which the security binding does not open. In soft deep snow, it is also difficult for trained skiers to get out of an awkward position without unbuckling the skis and often impossible to exert strong pressure on the opening link of the safety binding as there is normally no fixed abutment. Children and carvers often ride skis or similar equipment without poles. Again, a device that facilitates the opening of the bond is an advantage. For senior skiers, whose mobility is often restricted, the invention should also be useful. Other cases arise in fall injuries in which the safety bond has not triggered. Here, often because of the additional risk of injury or the generation of pain no strong pressure on the opening lever of the bond can be exercised.

The object of the invention is therefore to allow the opening of the binding by hand without the use of body weight or other strong pressure forces in all, even complicated body positions of the user and without outside help. This is achieved by a mechanism in which both levers and springs are used to reduce the strong forces required to open the binding. Also, the use of electrically powered motors is possible. In the invention, it is an accessory for already on the market for a long time security bindings of various brands and designs. They are usually provided with a lever for opening by the weight of the user with the help of a stick (ski stick). It is particularly important to ensure that the construction of the binding opener according to the invention has no influence on the security system of the binding. All parts of the binding opener can be made with all materials suitable for the particular function.

Description of an example operation in practice: The user involved, in this case skiers, has fallen into a predicament where he or she has failed to lift the safety binding, from which he or she no longer lifts up and also does not put sufficient pressure on the release lever can exercise the security bond. To get back on his feet, he has to take off at least one ski. He can now achieve in any situation the binding opener according to the invention by hand, operate without much effort and thus solve the ski.

An invention with a similar purpose is with DE 19528154 Registered. However, this is a pulley (pulley) for a special bond, however, has the considerable disadvantage of being prone to failure at low temperatures and icing. These disadvantages are avoided by the robust construction and the lining of the device according to the invention.

Description of the mechanism

The binding opener consists of one (or more) connecting part ( 1 ), which provides a firm connection between the ski ( 6 ) (o. Ä.) And one (or more) torsion spring ( 2 ), which above the rear binding head ( 8th ) is placed. The torsion spring ( 2 ) has the task, with the movable leg ( 3 ) over the push rod ( 5 ), or other parts for transmitting compressive forces, the spring force and the travel for the movement of the lever ( 4 ) of the security bond ( 8th ) to deliver. The torsion spring ( 1 ) is made by hand with the help of the thigh ( 3 ), which is in position G ( 1 ) (closed safety bond) by latching on the housing ( 7 ) o. Ä. Is fixed. The push rod ( 5 ), (or other parts for the transmission of compressive forces) is in order to exploit the leverage at a closer distance from the pivot point of the torsion spring ( 9 ) on the thigh ( 3 ) attached non-positively. Its length is designed taking into account the spring travel so that in the tensioned state (G) ( 1 ) a minimum distance to the lever ( 4 ) of the closed security bond ( 8th ) consists. This will affect the mechanism of the binding opener on the safety mechanism of the binding ( 8th ) avoided by disengagement and release of the thigh ( 3 ), the torsion spring ( 1 ) the adhesion to the lever ( 4 ) of the security bond ( 8th ) and the thigh ( 3 ) with the push rod ( 5 ) with the aid of the spring force and the spring travel up to the opening of the safety binding ( 8th ) (Pos. A) ( 2 ) move. The activation of the easily accessible leg ( 3 ) and thus the opening of the security binding ( 8th ) is manually possible with little effort. The position G ( 1 ), in which the binding opener is ready, can manually, u. U. also with the additional help of Closing process of security binding ( 8th ), getting produced. In position G ( 1 ) with engaged, tensioned spring leg ( 3 ), the fixed binding opener has no influence on the use of security binding ( 8th ). It can therefore be opened and closed in the usual way. The binding opener, however, is always ready for emergency use.
