Definitions
- the invention relates to a ski binding for a cross-country or touring ski with a holding shell, which is mounted both together with a swivel part designed as a two-armed angle lever and also for the purpose of transition between the closed and open positions relative to the swivel part about a ski-fixed, horizontal transverse axis.
- the first lever arm of the pivoting part carries at least one locking pin, wherein in the closed position of the binding, which is fixed by a resilient bolt, the locking pin of the pivoting part engages in a release of the holding shell and the holding shell overlaps a front sole extension of a ski boot, while the locking pin also an opening in the sole extension penetrates from below, whereas in the open position of the binding the locking pin is removed from the inside of the holding shell, the joint pivoting of the holding shell and the pivoting part around being on a skis bracket consolidated transverse axis against an elastic element is going on, the holding shell and the pivoting part are penetrated in their front area by the transverse axis and the pivoting part carries on its second lever arm an axis for the bolt which engages in the closed position of the binding on the holding shell , and wherein a spring holding shell and swivel part loaded in the sense of a spread apart.
- Such a ski binding is described in WO 87/03211.
- the pivoting part is designed as an angle lever and, in the closed position of the binding, can be pivoted together with the holding shell against the force of an elastic element.
- Such a cross-country ski binding with the matching cross-country ski boot is also commercially available and has proven itself in practice.
- the elastic element is arranged in front of the swivel part and is supported on an upwardly directed arm of the swivel part.
- the elati- see element itself is designed as a plastic block. In the unloaded position of the binding, this plastic block lies flat against the forward-facing side of the swivel part.
- the pivoting part is pivoted upwards together with the holding shell, the elastic element being compressed. Due to the pivoting movement and the change in shape of the compressed elastic element, the point of application of the respective restoring force changes during the pivoting.
- plastic springs age relatively quickly under the influence of the weather and solar radiation and then have to be replaced.
- the object of the invention is to avoid the disadvantages of the known ski bindings and to design a ski binding of the type mentioned at the outset in such a way that the restoring force of the spring acts at a point which can be selected by the designer and the spring characteristic can also be designed and selected is largely independent of external influences such as temperature, weather and pollution.
- the set goal is achieved according to the invention by the characterizing features of claim 1. Because the second lever arm of the swivel part - viewed in the closed and unloaded position of the ski binding - runs downwards and forwards, it is possible to protect the elastic element in Ski binding housing below to arrange the swivel element. This also makes it possible to use a metal spring which engages at a point on the second lever arm of the pivoting part which can be selected by the designer.
- FIG. 1 shows an embodiment of the cross-country ski binding according to the invention in longitudinal section, specifically in the position ready for entry
- FIG. 2 shows the cross-country skiing binding from FIG. 1 in the closed but unloaded position (sliding position)
- FIG. 3 shows the cross-country skiing binding in the walking position.
- front means towards the ski tip.
- a bearing block 30 is mounted on a ski 1 by means of indicated screws 2. It essentially consists of a base plate 31 and side walls 32. In the upper region of the side walls 32, recesses 35 are provided. The side walls 32 carry a transverse axis 3. A swivel part 40 is articulated on the transverse axis 3.
- the pivoting part 40 is designed as an angle lever, the first lever arm 41 of which extends to the rear and carries an upwardly directed locking pin 42, while the second lever arm 43 is inclined facing forward and downward.
- the second lever arm 43 has on its downward and rearward side a support surface 44 and a projection 45 for a spring 5, which spring 5 is arranged in an elongated recess 3 of the base plate 31.
- the spring 5 is designed as a helical compression spring and is supported on the one hand on the support surface 44 of the swivel part 40 and on the other hand on a rear boundary wall 34 of the elongated recess 33.
- the transverse axis 3 also carries a holding shell 50 for receiving a cross-country ski boot 20.
- the holding shell 50 has an exemption 51 for the locking pin 42.
- Guide strips 53 adjoin the side walls 52 of the holding shell 50 at the top.
- the side walls 52 of the holding shell 50 are connected by a transverse web 54.
- the crossbar 54 is designed at its front end as a detent 55, the first surface 56 of which extends approximately in the form of a cylinder jacket section about the transverse axis 3.
- a second surface or holding surface 57 which is also designed as a cylinder jacket section and which extends approximately in the direction of the transverse axis 3.
- An expansion spring 6 is arranged around the transverse axis 3 and acts on the swivel part 40 and the holding shell 50 in the sense of a spreading apart.
- a locking axis 7 extending transversely to the longitudinal direction of the ski is arranged.
- the locking axis 7 carries a locking bar 60 with a latching area 61 and a depression 62.
- the depression 62 enables the tip of a ski pole to be inserted in order to open the ski binding arbitrarily.
- the locking area 61 is arranged along a cylindrical surface, the axis of which forms the locking axis 7.
- An exemption 63 extends below the latching area 61.
- the latch 60 has 64 projections 65 on its side walls. The projections 65 are located somewhat below the locking area 61 arranges.
- a locking spring 8 arranged around the locking axis 7 acts on the locking bar 60 in the closing direction.
- FIG. 1 the front area of the cross-country ski boot 20 with a sole 21 and a hooking element 22 can be seen in FIG.
- This cross-country ski boot 20 is known, does not form the subject of this invention and is therefore not described in detail and is shown in broken lines in the drawing.
- FIG. 1 shows the cross-country ski binding according to the invention in the ready-to-go state and with the cross-country ski shoe 20 inserted.
- the holding shell 50 is pivoted downward against the force of the spreading spring 6, the locking pin 42 penetrating the free position 51 of the holding shell 50 and projecting into the opening between the sole 21 and the hooking element 22.
- the first surface 56 of the locking lug 55 slides out of the release 63 of the bolt and thus enables the locking spring 8 to pivot the bolt 60 in the closing direction until the locking region 61 of the bolt 60 engages with the holding surface 57 of the holding shell 50 is coming. This position is shown in Fig.2.
- the holding shell 50, the pivoting part 40 and the bar 60 with the cross-country ski boot 20 now form a movement unit.
- the walking movement i.e. when the cross-country ski boot 20 is lifted off the ski 1
- the holding shell 50, swivel part 40 and latch 60 are pivoted about the transverse axis 3, the spring 5 being compressed.
- the maximum pivoting movement is limited by the interaction of the projections 65 with the recesses 35.
