DESCRIPTION:
BRIEF SUMMARY
The invention relates to a binding for snowboards with a binding plate provided with lateral retaining members on both sides of the boot sole in its central longitudinal zone, the binding plate being connected to a base plate or the surface of the snowboard and also to a boot and such a binding for snowboards wherein the boot has an interface made from a preferably harder material than the boot body.
The riding of snowboards is connected with frequent stepping into and out of the binding. When queuing at a T-bar lift, a boot must be lifted out of the binding to make forward movement possible. In the case of other transportation means such as, for example, chair lifts or cable ways the snowboard is carried in the hand or mounted on the cabin, for which purpose the snowboarder must step with both boots out of the binding.
In known binding systems the mechanisms by which stepping out of the binding is made possible are situated directly on the surface of the snowboard, so that when stepping out of the binding the snowboarder must bend down low to be able to actuate the release mechanism by hand. A facilitation, which is achieved with traditional skis by actuating the release mechanism using the ski pole is not possible with snowboards, with which no poles are used. Stepping into the binding is also made difficult, since the snowboarder must step into the binding with the boot without being supported on ski poles. This may represent a difficult manoeuvre, more particularly on a steep piste. In prior art binding systems no means are present for the exact positioning of the boot in the binding.
For example, WO 96/05894 discloses a snowboard binding in which retaining parts of the binding engage on both sides of the boot sole in its central longitudinal zone. Locking is performed by a locking mechanism disposed at the side. By lifting the bolt, stepping out of the binding is made possible. However, this binding provides no adequate guiding function, so that an exact positioning of the boot in the binding is not easily possible.
It is an object of the invention to create measures which facilitate stepping in and out of the snowboard binding while avoiding the aforementioned disadvantages.
This problem is solved according to the invention by the features that the retaining members are formed by side walls, and disposed on the binding is a pivotable sprung clamp whose ends or elements such as, for example, bolts or the like connected to the ends extend inwardly through substantially horizontal holes in the side walls, while a boot can be locked to the binding via the ends of the sprung clamp or elements such as, for example, bolts or the like connected thereto, and again unlocked by the pivoting of the sprung clamp.
By the side walls the binding zone is fixed in position, whereby the exact placing of the boot in the binding is facilitated. During stepping into the binding the sprung clamp is pressed apart and finally the ends of the sprung clamp or elements such as, for example, bolts or the like connected thereto latch into devices provided for the purpose in the boot and therefore lock the boot to the binding. For stepping out the sprung clamp is pivoted, preferably pressed downwards and then by, for example, corresponding shaping of the side walls the sprung clamp is forced apart and therefore the ends of the sprung clamp or the elements such as, for example, bolts or the like connected thereto are drawn out of the locking devices of the boot, whereafter the boot is unlocked and the snowboarder can step out of the binding.
If the side walls diverge from one another conically upwards at least in the upper portion, stepping in is even further facilitated, since the snowboarder need not position his boot exactly on the binding. The boot is guided into the binding by the conical side walls.
Further advantages are achieved if at least one of the two side walls is adjustable in the transverse direction and is preferably fixable in the adjusted position or the two side walls are connected via a spring or the like.
