DESCRIPTION:
BRIEF SUMMARY
SPECIFICATION
The invention relates to the arrangement of a cross-country, particularly skating binding and a shoe adapted thereto, which has on its forward sole complementary engagement members introducible into engagement members of the binding in order to produce a joint-like connection, the engagement members on the sole comprising a bracket extending transversely to the longitudinal direction of the sole and roughly parallel to the tread surface of the sole and located off-set relative to the forward sole end, and the complementary engagement members on the binding comprising a retaining hook engaging over the bracket, particularly from behind, which is movable from a closed position into a release position and vice-versa.
Such an arrangement is known from DE 43 43 485 C1. This known arrangement is characterised by a simple and compact construction. In addition, it ensures exact ski guidance and maximum power transmission even during so-called "skating. Thus in the known construction an essential factor is not only the arrangement of the joint axis in the ball region of the forward shoe sole, but also the arrangement of a resilient contact member in the region of the joint axis between the sole and the ski cover surface.
A quite similar construction is disclosed in DE 44 28 154 A1.
A disadvantage in the known arrangement, which is ascribed to the same inventor as the present invention, is the lack of reliability in handling when stepping into or out of the binding.
Therefore the object underlying the present invention is to improve the reliability of handling of the edge arrangements. In particular it is to be ensured that, during use, the retaining hook remains in a closed position even under alternating and heavier loads.
This object is achieved by the characterising features of claim 1. By virtue of the fact that the retaining hook is initially tensioned in the closed position it is ensured that this latter remains in the closed position even under alternating and heavier loads. The retaining hook can be brought into its release position contrary to the initial tension. Particularly advantageous constructive embodiments therefore are described in claims 9 and 10, to which reference is particularly made here. Accordingly, in a preferred embodiment, there engages on the retainer hook a clamp cable, which is preferably led round behind the heel of the shoe, and upon which a clamp lever engages in such a way that by depressing the latter, the clamp cable is drawn backwards, correspondingly carrying with it the retainer hook contrary to the action of the resilient members initially tensioning it in the closed position. This construction applies for a retainer hook which engages over the bracket integrated with the sole from behind.
Insofar as the construction is so designed that, in order to produce a joint-like connection between shoe and binding, the retaining hook engages over the bracket integrated with the sole from the front, the clamp cable engaging on the retaining hook is oriented forwards, and coupled with a clamp lever mounted to pivot in front of the shoe in such a way that when the clamp lever is depressed, the clamp cable is drawn forwards, correspondingly taking with it the retaining hook contrary to the action of a member initially tensioning the latter in a backward direction.
Insofar as the binding is constructed as a so-called "step-in binding, the retaining hook is held in its release position by a retaining member which may be acted on by the bracket on the sole when stepping into the binding in such a way that, when the retaining member is acted upon, the retaining hook is released for movement into the closed position. For this purpose, there is preferably arranged on the upper side of the retaining member a projection, e.g. a pin or the like, corresponding with the bracket on the sole when stepping into the binding. This projection is initially acted upon when stepping into the binding by the sole bracket and pressed downwards. In this way the retaining member is released from t
