DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a sole-support device.
BACKGROUND OF THE INVENTION
Such a device is already described in with reference to FIG. 5 of Austrian Patent No. 302 129. This device has the disadvantage that the band in which bearing axes are supported, which band is thicker than the height of the two moldings, is pressed forwardly beyond the edge by the ski boot when the skier steps with the ski boot into the binding and thus is easily damaged.
A similar disadvantage exists in the design according to U.S. Pat. No. 3,845,965, in which the band is only guided in lateral grooves in a plate-shaped support member. Thus, lateral moldings are missing in this design (see FIGS. 2 to 5).
This is also true for the device according to Austrian Patent No. 311 231, in which the position of the band in longitudinal direction of the ski is only defined by the bend in the support member.
Finally U.S. Pat. No. 3,488,990 shows a closed flat cushion in FIG. 5, which cushion houses a lubricant and is fastened on the upper side of the ski by means of an adhesive. The cushion is in the ball area of the ski boot. This cushion is supposed to make the release of the ski boot easier during a twisting fall of the skier.
SUMMARY OF THE INVENTION
The invention has the purpose of overcoming the disadvantages of the known designs and to provide a sole-support device which reliably avoids damage to the endless band when the skier steps with the ski boot into the binding.
This purpose is attained according to the invention by making the support section of the band thinner than the height of the two moldings, so that a reliable guiding of the band relative to the support member is assured, even when elastic bands are used. In addition, a reliable contact of the ski boot with the band is created by arranging elevations on the band.
Various solutions are offered for the design of the elevations. Raised ribs, which extend transversely to the length of the band, has proven to be particularly advantageous, since this measure prevents an unintended placement of the ski boot on the lateral moldings, even when the skier is a heavy person.
A breaking of the support member into multiple components eases the installation of the band through the provision of an adjusting mechanism for the support section of the support member.
The adjusting mechanism can be a key or a cam-shaped or eccenter-shaped rotatable insert insertable between the multiple components.
The support section of the support member, which support section is used to support the band, is formed by two tensioning parts which are supported in transversely extending guideways on the support member and are pressed outwardly by at least one spring. This assures an even tensioning of the band.
The spring or springs can thereby be formed by two bars resting against one another and being die-cast of plastic together with the two tensioning parts.
The installation of the band becomes particularly easy by breaking the support member into two parts.
The provision of a cover plate substantially protects the inside of the device against the influences of the environment. A low friction course is guaranteed for the band by the surface design of the cover plate. The position of the cover plate in the device is thereby reliably and favorably assured by the measures of a cover plate locking structure.
An easy installation or mounting of the two tensioning parts together with the band in the support member of the device can be accomplished by providing a groove into which is received the band.
One can prevent an unintended lifting of the band off from the support member by providing an edge structure on the band which operatively grips structure associated with the support member.
Further structure can be provided on the support member for guaranteeing a reliable connection of the two parts of the support member and yet have the additional advantage that the support member, during assembly, can easily be adjusted to the width of the band being used. The band can therefore d
