BRIEF SUMMARY
FIELD OF THE INVENTION
The invention presents an improvement to a ski binding which is known from the document WO94/09870 and in which a heel part can be adjusted in the longitudinal direction relative to a guide fixed to a ski and can be secured in predetermined variable sections. Provided, in this arrangement, on a locking piece are latching means which can be engaged with, and disengaged from, mating latching means of a guide fixed to a ski.
BACKGROUND OF THE INVENTION
In this arrangement, a connecting arm engages beneath the locking piece at its rear end section, which is arranged in a freely accessible manner at the rear part of the ski binding.
When a ski boot is inserted, the heel part slides further rearwards in the guide, with further compression of a spring which acts on the locking piece. This means that there is the possibility, in extreme positions, of the locking plate and the connecting arm being disengaged from one another, this resulting in the risk of it no longer being possible to carry out a longitudinal adjustment by hand.
The action of the spring which acts on the locking piece may be obstructed by dirt or the like.
It is, then, the object of the invention to provide a ski binding which permits rapid and simple adjustment of the heel part relative to the guide fixed to a ski, the intention being for it to be possible to carry out the unlatching operation, without tools and with a low amount of force, even by exerting pressure with only one hand. Furthermore, it is intended to provide a protection device which prevents involuntary release of the latching, e.g. by a ski pole, and there is the additional intention of providing means for, if necessary, assisting the function of the spring which acts on the locking piece.
It is likewise intended to ensure a configuration which rules out the situation where the locking plate becomes disengaged from the connecting web.
SUMMARY OF THE INVENTION
The object set is achieved according to the invention by the designing a connecting arm in a U-shaped manner, said arm providing the bent region of the locking plate with a lengthened contact surface, in the case of the heel part being displaced longitudinally counter to the force of the spring. A protecting support portion which prevents involuntary unlatching due to external influences is formed by the connecting arm being bent in the direction of the upper side of the ski.
The action of the spring is assisted, in the case of, for example, dirt, in that a restoring arm is bent out of the locking plate and, if required, deliberate pulling on the opening lever can exert an additional pressure on said restoring arm, this additional pressure permits a latching operation.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention, together with the advantages thereof, is explained hereinbelow by way of exemplary embodiments, with reference to the drawings, in which: FIG. 1 shows a schematic side view, partly in section, of a ski binding according to the invention, with the locking piece latched into a guide fixed to a ski,
FIG. 2 shows the binding in a view as in FIG. 1, but
with the locking piece unlatched,
FIG. 3 shows a graphical representation of the locking piece and the opening lever acting thereon,
FIG. 3a shows a modification of the opening lever, and
FIG. 3b shows the end section of the locking plate with a bent-out restoring arm.
DETAILED DESCRIPTION
According to FIG. 1, the heel part 101 of a ski binding is positioned along a guide 102 fixed to a ski, e.g. screwed onto a ski.
The heel part 101 comprises a housing 103 and a sole-retaining means 104 which can be pivoted with respect to the housing and can be latched in and released under specific force conditions.
The intention is that the heel part 101 depending on the boot size - can be latched releasably in various positions relative to the guide 102. For this purpose, a locking piece 105 is provided within the housing 103, which locking piece has a bearing and spring-guiding body 106 and a locking plate 107. The latter can be seen more clea
