Rotary attachment device for snowboards

Abstract

The present invention relates to a binding device for snowboards which allow binding a boot onto the snowboard, comprising a base plate (4) which is attached to the board by means of an anchoring disc (3) and a support plate (2) forming the support for the attachment of the boot, where said base plate (4) in turn comprises in its first section anchoring grooves (9) allowing a relative anchoring position of the support plate (2) through an anchoring part (6) and a guiding part (5) which are attached to the support plate (2) by means of bindings, said anchoring part (6) and guiding part (5) being what allow the relative longitudinal forward and backward movement for engaging and disengaging said support plate (2) with respect to the base plate (4) once the anchoring part (6) is released by releasing at least one anchoring tooth (7) belonging to said anchoring part (6) from the anchoring grooves (9) of the base plate (4) through locking means with at least one retention bolt (23) which is activated by pulling on a pulling member (22); and where when said support plate (2) reaches the relative free position by performing the longitudinal forward movement, being able to thus perform a relative rotational movement between both plates facilitated by at least one curved section both of the base plate (4) and of the anchoring part (6) and guiding part (5).

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention is applied in the extreme sports sector and more specifically in skating or sliding on snow-covered surfaces with a board called snowboards, and it relates to binding devices which allow the rotation of the rider's boot with respect to the board.[0002]More specifically, the object of the invention allows releasing the original position of the boots with respect to the board, which for the rider involves putting his / her knees in a comfortable position when he / she is not going down the snow-covered slope, when sitting on a ski lift or when he / she crosses flat surfaces, among others, thus preventing torsional stresses on the knees and therefore possible injuries.BACKGROUND OF THE INVENTION[0003]One of the main problems existing today in the sector of skating with a snowboard is that when the board is fixed on the rider's feet, it is in a position perpendicular to the forward direction of human movement or to the transport dire...

AI Technical Summary

Benefits of technology

The invention proposes a binding device for skis that allows for a relative movement of the support plate with respect to the base plate, both by longitudinal movement and by rotational movement. This device improves on existing bindings, reducing the likelihood of knee injuries and providing a simple and cost-effective solution for riders. The technical effects of the invention include improved safety and a simplified design that reduces the risk of injury and minimizes the discomfort for riders.

Problems solved by technology

One of the main problems existing today in the sector of skating with a snowboard is that when the board is fixed on the rider's feet, it is in a position perpendicular to the forward direction of human movement or to the transport direction of a drag lift, chair lift, ski lift or any transportation means commonly used for carrying a rider to an area located at a different level for him / her to subsequently skate down or for carrying said rider to any other place.

This position is also inevitable when the rider is mounted on said chair lifts, such that he / she always ends up invading the space of the contiguous seat causing inevitable crashes into the board with the equipment of other riders.

This problem becomes more pronounced in the cases of using a drag lift which consists of transportation means where the rider is dragged with his / her feet on the board in contact with the ground, dragging the board along as it moves forward, causing significant excess torsional stress on the knee, particularly in cases of going down a slope, where the force of gravity must further be overcome, in addition to the force of snow friction and of the weight of the board itself, causing short- and long-term knee injuries.

Some documents disclose inventions which consist of bindings that allow rotation, buy they require either removing the boot from the foot for establishing a new position, or it is a more complex mechanism that requires binding the board to the foot such that it remains in the desired position, but not a free position, so the described problem remains unsolved.
