DESCRIPTION:
BRIEF SUMMARY
The present invention is concerned with a device for fastening a shoe to a snow board and, more particularly, a safety fastening device, i. e. one which is disengaged in the case of a fall, an impact or a torsion and which includes a system which is automatically engaged when stepping into it, as well as a snow board shoe designed for cooperating with this fastening device.
Presently, snow surfing on a snow board is generally practised without any safety fastening means, contrary to conventional mountain skiing where, for example, a front bracket and a back bracket are provided to lock the shoe to the ski. Safety fastening means for snow boards have already been disclosed, for example in document FR-A-2,618,688, which include, for example, on a support which is fastened to the board, a front stop and a heel piece, similar to the safety fastening means used in conventional mountain skis. Such devices suffer the same drawbacks as those designed for mountain skis in that their safety is inadequate in case of an impact along the axis stop--heel piece and because of the accurate adjusting needed, which depends on the length of the sole of the shoe to be fastened; furthermore, the presence of two mechanical devices, a front one and a back one, respectively, adds weight in an undesirable manner to the snow board.
Fastening devices for snow boards are also known which are of the so-called central type (or with lateral jaws), in particular such as those described in the patent CH 682,133. However, this central fastening necessitates that the user carries out an operation on the device for bringing the jaws from their open non operative position to their closed operative position, for example by operating manually a lever. However, this operation can be difficult to carry out for certain users or when the snow board is in a situation where it is partly covered with snow.
Accordingly, the purpose of the present invention is to provide a safety device for the fastening of a shoe onto a snow board which does not suffer the above described drawbacks of known fastening devices, and which makes it possible, in particular, to use the same fastening device for shoes of differing lengths and which further includes a system which is engaged automatically when stepping into it.
A second object of the invention is a shoe for a snow board designed for fastening on a snow board by means of a safety fastening device according to the invention.
The invention will be described in detail hereafter, with reference to the annexed drawing. This drawing illustrates schematically and by way of example a particular embodiment of the invention.
FIG. 1 is a plan view and FIG. 2 is a front view, both showing the sole portion of the fastened shoe.
FIGS. 3 and 4 are views, partly in cross-section, taken horizontally and vertically, respectively, in the operative closed position.
FIGS. 5 and 6 are views partly in cross-section, taken horizontally and vertically, respectively, in the non operative open position.
With reference firstly to FIGS. 1 and 2, the embodiment of the fastening device according to the invention illustrated by way of example includes a housing 1 designed for receiving the mechanism for fastening to the upper surface S of a snow surfboard and two lateral jaws 2 actuated by said mechanism and provided each one with prehensile claws or fingers 3; these claws 3 are designed for holding in the operative closed position a patterned or profiled section C which is integral with the sole of the shoe to be fastened (not illustrated), or is a portion attached beneath the shoe (see FIG. 2).
In practice, two fastening devices such as that illustrated in FIG. 1 are fastened to the snow board, running parallel to each other or not, and at an angle with respect to the longitudinal axis of said snow board which depends, in a manner known per se, on the requirements of the practice of this sport and on the choice made by the user. Means can also be provided between the housing 1 and the surface S of the snow board to allow an easy adjustment
