BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a ski brake. A similar ski brake is known for example from AT-8701243.
BACKGROUND OF THE INVENTION
A rigid intermediate member is hinged in the ski brake on bent end sections of two multiply bent wire-brake arms, which end sections are housed in the operating pedal. The intermediate member has a cylindrical sleeve and an extension following the sleeve, which extension, in the ready position of the ski brake, is supported on a support surface of the base plate against the force of a connecting spring connecting the bent end sections of the wire-brake arms.
This ski brake has proven to be successful, however, it was found that certain unfavorable circumstances can hinder the pivoting movement of the brake arms from the ready position into the braking position. For example, the brake arms can be bent caused by a rough operation or it is possible that the width of the skis is greater than is generally common. It can then happen that at least one brake arm gets caught on the side edge of the ski and the braking action is reduced or does not take place.
The goal of the invention is to improve this known ski brake so that a pivoting of the brake arms into the ready position occurs reliably also under unfavorable conditions.
SUMMARY OF THE INVENTION
A ski brake comprising two wire-brake arms pivotally supported in a base plate, which wire-brake arms can be pivotally moved into their ready or retracted position by pressing down an operating pedal against the force of an erecting spring. The end sections of the wire-brake arms are housed in the operating pedal and are connected by a connecting spring, to which an intermediate member is hinged. An extension of the intermediate member is supported on a support surface of the base plate. In order to enable a reliable functioning of this ski brake also under difficult conditions and in order to prevent a snagging of the wire-brake arms on the upper side or the side edges of the ski, the invention provides that between the area of the base plate carrying the support surface and the crossbar of the intermediate member there is provided an elastically flexible interconnection. By providing an elastically flexible support between the section of the base plate carrying the support surface and the crossbar of the intermediate member, it is assured that the wire-brake arms, even under more difficult conditions during the upward pivoting movement from the ready position into the braking position, can carry out the necessary movement to the outside, thus reliably preventing the wire-brake arms from getting caught on the sides of the ski.
Due to the fact that the base plate has in its section carrying the support surface a through-going groove-shaped opening extending over the entire width of the support surface and arranged approximately parallel thereto, the support surface can, when needed, move back or rather spring back.
BRIEF DESCRIPTION OF THE DRAWINGS
Further advantages, characteristics and details of the invention will now be discussed in greater detail in connection with the drawing, which shows one exemplary embodiment of the ski brake of the invention.
FIG. 1 is a vertical longitudinal center cross-sectional view of the ski brake in the braking position,
FIGS. 2 and 3 illustrate a detail of FIG. 1,
FIG. 4 is a top view of the base plate of the ski brake,
FIG. 5 is a view like FIG. 1, but with the operating pedal and brake being in the fully retracted position,
FIG. 6 is a view like FIG. 2, but of a modified construction of the bearing block, and
FIG. 7 is a fragmentary view of a modified form of an intermediate member.
DETAILED DESCRIPTION
The ski brake illustrated in FIGS. 1 to 4 is identified in its entirety by the reference numeral 1. It has a base plate 2 with a base 2a fastened on a ski 10, for example, by means of only schematically indicated screws 3. FIG. 1 shows further a portion of a mounting plate 11 serving as a holding element for a ski-binding part here not illustrated and screwed together, wit
