Description

The invention relates to a binding for snowboards according to the Preamble of claim 1 and a shoe and a such binding for snowboards according to the generic term of Claim 8.

Driving snowboards is with a frequent in and out Get out of bond connected. When hiring at one Drag lift must be climbed out of the binding with a shoe to enable moving. With others Means of transport, such as chair lifts or The snowboard is carried in the hand or on the cable car Cabin mounted, which is why the snowboard rider with both shoes must get out of the bond.

The mechanisms with are in known binding systems who are immediately released from the bond on the surface of the snowboard Getting out of the binding has to bend down to get with to be able to operate the trigger mechanism by hand. A Relief, as with conventional skis, by actuation the release mechanism is achieved with the help of the ski pole not possible with snowboards where no poles are used. Getting into the binding is also difficult because the Skier with the shoe in the without the support on ski poles Binding must get in. This can, especially on a steep slope are a difficult maneuver. With previous ones Binding systems are not a means of precisely positioning the Shoes in the binding.

For example, WO 96/05894 describes a snowboard binding, on both sides of the shoe sole in its central longitudinal area Attack the holding parts of the binding. The locking takes place through a side locking mechanism. By Lifting the latch will exit the binding enables. However, this binding does not offer sufficient Guiding function, which ensures exact positioning of the shoe is not easily possible in the bond.

A snowboard binding of the type specified is, for example, from known from DE 296 08 353 U1. The aim of this construction is Creating a constructively simple, inexpensive and easy manageable binding, which is a high entry comfort and offers a secure hold. In addition, the use of Snowboard boots also on conventional standard bindings and one simple retrofitting of standard shoes is made possible. This is achieved in that the binding element at least one at least approximately parallel to the surface of the snowboard an energy storage slidably mounted, above Locking element that has a projection of the shoe engages and / or engages in a recess of the shoe. For Unlocking the locking element against the Lift mechanism can be withdrawn. This is done, for example with the help of Bowden cables, which are guided in channels and with an actuator are connected.

The object of the invention is to create measures which Avoid getting in and out of the snowboard binding of the disadvantages mentioned above.

The object of the invention is achieved in that the Elements the ends of a pivotally hinged to the binding Form spring clip or are connected to them, the Shoe from the binding again by swiveling the spring clip can be unlocked. The binding area becomes through the side walls fixed, which ensures the exact placement of the shoe in the Bond is facilitated. When entering the binding, the Spring clip pressed apart and finally the ends snap the spring clip or related elements such as bolt or the like. In intended devices in the shoe and thus lock the shoe with the binding. To get out the spring clip is pivoted, preferably depressed and then by e.g. appropriate design of the side walls Spring clip pressed apart and thus the ends of the Spring clip or the associated elements such as bolt or the like. From the locking devices of the shoe pulled out, whereupon the shoe is unlocked and the Snowboarders can get out of the bond.

If the side walls at least up in the upper section diverge conically, the boarding gets even further relieved, since the snowboarder does not fit his shoe exactly on the Position binding. The shoe is conical Side walls led into the binding.

Additional benefits are achieved if at least one of the two Side walls of the binding is adjustable in the transverse direction and in the set position is preferably fixable or the two Side walls are connected by a spring or the like.

According to a further feature of the invention, the spring clip preferably the one furthest from the binding Place with a preferably upward-pointing bracket or the like. connected or trained as such. Through the bracket or the like. is the actuation of the spring clip to unlock the shoe in the bond eased. If possible, the bracket or the like. protrude as far as possible so that the snowboarder must bend as little as possible when exiting the binding.

If the spring clip can be moved in the longitudinal direction to adapt to the shoe size, it can the spring clip when entering the binding as a further positioning aid serve. Furthermore, the spring clip, which is precisely matched to the shoe size, can be in the Engage the shoe with the provided notch or the like.

To ensure a movement of the binding relative to the snowboard can be between the Binding plate and the base plate or the surface of the snowboard an elastic Material, e.g. be arranged in the form of an O-ring. This creates a three-dimensional The mobility of the binding in relation to the base plate or the snowboard achieves what has a positive effect on driving characteristics.

In addition, by several between the binding plate and the base plate or Set screws on the surface of the snowboard for adjustable connection of the Distance between binding plate and base plate or surface of the snowboard Elasticity of the interposed material can be adjusted. This measure can the mobility in different spatial directions to optimize driving characteristics to be influenced.

The object of the invention is also achieved by a shoe and a binding the above-mentioned features, wherein the mounting unit ("interface") from the central area the sole of the shoe extends at least partially conically outwards and upwards laterally essentially horizontal holes or the like. For locking the shoe with a Has bond. The zone formed by the assembly unit made of harder material facilitates getting into a binding, which with appropriate means for snapping into place are carried out in the devices provided on the shoe. Thereby. that the Mounting unit runs according to the invention only in the middle region of the sole, the sole can the front and rear areas are soft. which makes walking comfortable is increased. The hard zone on the shoe creates a firm connection with the binding possible. The material of the assembly unit can also be identical to that of the protective body be and therefore have the same hardness.

According to a preferred embodiment, the assembly unit has one or more Buckles of the shoe connected.

Additional advantages regarding the stability of the shoe can be achieved if the Assembly unit with a sleeve or the like. Made of preferably harder material than that Shoe body is preferably articulated.

Finally, the best and simplest solution to the problem according to the invention is one Combination of binding and boot for snowboards with at least one of each previous features wherein the ends of the spring clip or connected thereto Elements such as Bolt or the like. In a position of the spring clip in the holes in the Assembly unit of the shoe for locking the shoe with the binding protrude and that the Ends of the spring clip or elements connected to it, e.g. Bolts or the like Swivel the spring clip from this position out of the holes in the assembly unit of the shoe can be deflected from the binding to unlock the shoe. The apply advantages already mentioned above.

When part of the spring clip is in the locked position in a designated notch or the like. The shoe engages, an additional security of the lock is created.

The features of the invention are explained in more detail with the aid of the accompanying figures.

1 has a spring clip 1, which around the Heel area is closed. In theory, the spring clip 1 could also around the Toe area should be closed. The ends 2 of the spring clip 1, which in the direction are biased towards each other, project through substantially horizontal holes 4 in the Side walls 3. The side walls 3 are fastened or welded to the binding plate 5 or the like. Advantageously, the binding plate 5 and the side walls 3 are made of one piece manufactured. The side walls 3 form a guide for the shoe and facilitate this Get in and correctly position the shoe in the binding. Getting in is still more easily if the side walls 3 at least in the upper section conically upwards diverge. The part of the spring clip 1 that protrudes the most from the binding is designed in the form of a bracket 9. Of course, this can be used to actuate the spring clip 1 serving bracket 9 can also be arranged laterally. but advantageously it is located on the highest point of the spring clip 1 in order to actuate it as comfortably as possible shape. Instead of the configuration of the spring clip 1 in the form of a bracket 9 or the like can a corresponding element can also be connected to the spring clip 1. The Binding plate 5 is with a base plate 6 via a central fastening screw 7 connected. It could be the binding plate 5 directly with the surface of the snowboard be screwed. Instead of the screw 7 are of course other fasteners possible. So-called set screws 8 are used for the adjustable connection of the distance between the binding plate 5 and the base plate 6 or surface of the snowboard. The The purpose of the set screws 8 is explained below with reference to FIGS. 3a and 3b. By the Actuation of the spring clip 1, preferably by pressing down, is carried out by e.g. corresponding design of the outer surfaces of the rope walls 3, the spring clip 1st pressed apart and thereby the ends 2 of the spring clip 1, which for locking serve the shoe with the binding, pressed apart.

In FIG. 2, compared to FIG. 1, the ends 2 of the spring clip 1 do not point through the holes 4 in FIG Side walls 3, but bolts 2 ', which are connected to the ends of the spring clip 1. Instead of the bolt 2 'are other elements that are used to lock the shoe with the Binding are suitable. possible. In the example shown, the spring clip 1 can be compared the bolt 2 'are moved. This makes it easy to adjust the binding different shoe sizes possible. The example shown is in the open state the spring clip 1 is inclined downwards. When closed, in which the shoe on the Binding is fixed. the spring clip 1 is directed upwards. An exit is through Pressure on the bracket 9 of the spring clip 1 allows. If the spring clip 1 to the Shoe size is adjusted. so the part of the spring clip 1 formed as a bracket 9 at Getting in serve as a further positioning aid. The shoe is placed in the heel positioned guide and then by tilting the shoe forward this is fixed with the binding.

3a and 3b show two embodiments of the snowboard binding according to the invention on average from the side. Between the binding plate 5 and the base plate 6 there is an elastic material in the form of an O-ring 10. If the binding plate 5 mounted directly on the surface of the snowboard. can the elastic material too be arranged between binding plate 5 and snowboard surface. Through this Measure will have a slight three-dimensional mobility between binding and Base plate 6 or surface of the snowboard approved. The central one Fastening screw 7 for fastening the binding plate 5 to the base plate 6 in the middle of the O-ring 10. By adjusting the screw 7 or similar Fastening means, the elasticity of the material of the O-ring 10 can be changed. By the set screws 8 between the binding plate 5 and the base plate 6 or surface of the snowboard. which are arranged outside the O-rings 10. can agility the binding plate 5 relative to the base plate 6 or surface of the snowboard in Dependence of the direction can be set, which can be advantageous for the driving characteristics can. In FIG. 3b, the O-ring 10 has one in relation to the O-ring 10 from FIG. 3a different cross-section in the shape of a cone.

Fig. 4 shows the binding with a shoe in side view. The shoe body 11 is with a Assembly unit ("interface") 12, preferably made of harder material than the shoe body 11 provided which extends in the central zone of the sole 14 and on both sides of the Shoe runs upwards. Laterally, the assembly unit 12 is essentially horizontal Holes 13 on. through which the ends 2 of the spring clip 1 or connected thereto Elements such as Engage bolt 2 'or the like and lock the shoe in the binding. Due to the laterally conical mounting unit 12, the boarding in the binding further facilitated. When entering the binding, the bolts 2 'on the The spring clip 1 is pushed apart and the spring clip 1 springs back due to the tension above, while at the same time the bolts 2 'snap into the holes 13 in the assembly unit 12. The Spring clip 1 can snap into a notch 17 of the shoe, provided the spring clip is adapted to the shoe size.

5a to 5d are different embodiments of the invention Snowboard shoe shown. 5a shows a snowboard boot consisting of a Shoe body 11 and the assembly unit 12 which has a buckle 15 of the shoe is connected and is articulated with a sleeve 16. 5b is the Cuff 16 extended upwards and offers additional support. In Fig. 5c that with the Assembly unit 12 articulated sleeve 16 around the upper part of the shoe arranged and connected with a buckle 15. In the embodiment according to FIG. 5d the assembly unit 12 is pulled up to the edge of the shoe body 11 and the Assembly unit 12 connected to two buckles 15 of the shoe. A bigger one Assembly unit 12 or a connection with any sleeves 16 or the like offer one greater hold in the binding but less comfort when walking with the shoe, whereas a small assembly unit 12 has less hold in the binding but for that offers greater comfort when walking. Depending on the application and the desire of the Snowboarders have to compromise between binding and comfort be found while walking.

The representations are merely exemplary embodiments which are within the scope the invention can be modified in many different ways.
