Definitions

  • the invention relates to a ski binding for a cross-country or touring ski according to the preamble of claim 1.
  • the holding element receives a hooking element of the ski shoe, which extends approximately horizontally forwards from the tip of the ski shoe, is rigidly connected to the front end of the ski shoe and has a section which runs transversely to the longitudinal axis of the ski shoe and is arranged at a distance from the tip of the ski shoe to be able to be placed on the holding element.
  • the locking member of the known solution consists of a generally U-shaped bracket when viewed in plan view, to which a pressure element is articulated. The free end regions of the U-shaped bracket engage in the holding element and thus form a second pivot axis for the locking member.
  • This configuration means that the locking member must always be operated manually to fix the position of the ski boot on the ski binding, so that there is no automatic step-in entry.
  • Another disadvantage of the known solution is that, owing to the design of the locking member as a toggle lever, loosening can occur due to repeated actuations between the individual components of this locking device, in which case the condition of excluding any relative movement between the holding element and the hooking element is not guaranteed with certainty .
  • the holding element has two extensions into which appropriately designed slots of the ski boot can be inserted from above.
  • the spring-loaded locking member is initially pivoted during an entry process and brought into the latched position by the spring when the ski boot is fully inserted.
  • the spring just mentioned corresponds to the spring referred to in the present application as the second spring.
  • the spring according to the prior art is disadvantageously between the support body and the locking member, whereby a stronger spring must be provided.
  • an elastic component is used, which does not continuously support the holding element, but only during a pivoting process, after a certain pivoting angle, from which the unit consisting of the retaining element and the locking member acts. This discontinuous exposure to cross-country skiing can cause jerky loads, which can have an uncomfortable effect on the skier.
  • the object of the present invention is to improve the known solution both in structure and in effect. Furthermore, undesired, system-related loosening or wear-out should be avoided and comfort should also be improved by an automatic step-in.
  • the binding is compact, enables an automatic boarding (step-in) and there are no signs of wear and tear because there is no toggle lever which, when actuated, would have to overcome a dead center position.
  • a preferred embodiment of the invention is that the first spring acting on the holding element is designed as a leaf spring or a leaf spring assembly, one end of which is screwed together with the base body of the holding element onto the ski.
  • a particularly compact construction of the ski binding is ensured according to the invention in that the holding element, viewed in elevation, is approximately L-shaped and can be pivoted together with the likewise approximately L-shaped locking member against the force of the first spring.
  • the invention provides that a cutout is provided in the horizontal section of the L-shaped holding part, which is delimited in its upper area by funnel-shaped inclined surfaces.
  • the second spring is arranged with one end portion in a recess of the vertically extending portion of the L-shaped holding part and with its other end portion in a recess of the vertically extending portion of the L-shaped locking member. In this way, the opposite areas of the holding part and the locking member are used to receive the second spring acting on them.
  • the pivoting movement of the locking member is limited according to the invention in a simple manner in that the base body one up projecting web, the free end portion of which is closed with an inclined surface which forms a stop for the locking member.
  • This inventive concept is further favored in that the locking member has an inclined surface in its front region, which runs parallel to the inclined surface of the web of the base body.
  • a particularly advantageous and secure mounting of the ski boot used is achieved according to the invention in that the locking member has at its rear end area a rearward projecting approach to the ski boot to be inserted, the end area of which is closed with an inclined surface, and that the connection area of the ski boot has a lock which, when the ski boot is inserted into the binding, is overlapped by the base
  • the ski boot associated with the binding is characterized according to the invention in that the ski boot has a front support region which is congruent with the support surface of the binding, and in that the transverse axis of the ski boot is held on this by two webs of the connection region of the ski boot.
  • FIG. 1 shows an elevation of the binding according to the invention
  • FIG. 2 shows a top view of FIG. 1
  • FIG. 3 shows the connection area of a ski boot for interacting with the ski binding in elevation
  • FIG. 4 shows a top view of FIG. 3
  • FIG. 5 shows a front view of the ski boot according to FIGS. 3 and 4.
  • the ski binding As can be seen from FIGS. 1 and 2, the ski binding, designated in its entirety by 1, is fastened to the top of a ski 2 by means of screws 3, which are only indicated in FIG.
  • the part of the ski binding 1 resting on the top of the ski 2 is a base body 4, which carries an axis 5.
  • a holding part 6 and a locking member 7 to be described in more detail are pivotably mounted on the axis 5.
  • the holding part viewed in elevation, has an approximately L-shaped shape.
  • a cutout 6a is provided in the horizontal section of the L-s, which is delimited in its upper region by obliquely widening inclined surfaces 6b and 6c. The operation of the inclined surfaces 6b, 6c will be discussed later.
  • a recess 6d is provided, in which one end region of a spring 8 is seated.
  • the spring 8 is designed as a helical compression spring.
  • the locking member 7 in turn is also approximately L-shaped, but with the difference that the free end region of the vertical section of the L-s is penetrated by the axis 5 and thus the L is, so to speak, upside down.
  • the horizontal section of the L-s extends with respect to the axis 5 to the horizontal section of the L-shaped holding part 6 in the same mirror image to the front.
  • the horizontal section of the locking member 7 has an inclined surface 7a in the front area, a receiving point 7b for inserting the tip area of a ski pole and, at its rear area, an extension 7c projecting towards the ski shoe to be used.
  • the approach 7c serves as a locking lug and is closed at its lower end with an inclined surface 7c l .
  • the slope runs at an acute angle, which is closed towards the end of the shoe.
  • a recess 7d is provided, in which the other end region of the spring 8 is seated.
  • the base body 4 has an upwardly projecting web 4a, the free end region of which is closed with an inclined surface 4a l , which runs parallel to the inclined surface 7a in the front region of the locking member 7 and forms a kind of stop in its open position.
  • a spring assembly 9 consisting of several leaf springs is provided, the other end region of which is supported on the front of the holding element 6.
  • the holding element 6 and the locking member 7 can therefore be pivoted together about the axis 5 against the force of the spring assembly 9. Furthermore, the locking member 7 can be pivoted relative to the holding element 6 against the force of the helical compression spring 8 for the purpose of closing and opening the binding.
  • connection area essential for the invention is shown in FIGS. 3 to 5. It can be seen that the ski boot 11 has a front support region 12 which extends essentially vertically to the ski boot sole 13. Approximately at the level of the sole of the ski shoe, a transverse axis 14 passes through the connection area. The transverse axis 14 is held by two webs 15, 16 of the connection area of the ski shoe, the transverse axis 14 being in the cutout 6a of the holding part 6 in the inserted state of the ski shoe 11 in the ski binding 1 .
  • the transverse axis 14 in the connection region of the ski boot becomes the inclined surface 6b of the holding part 6, then the ski boot 11 is pressed down, the locking member 7 being pivoted through the support region 18 of the ski boot against the action of the spring 8.
  • the locking member pivots in a clockwise direction when the spring 8 acts on it, the inclined surface 7c l of the extension 7c above the lock 17 of the connection area of the ski boot 11 for lying is coming. Since the ski boot 11 rests with its support surface 18 on the support region 7d of the locking member 7, the ski boot 11 is securely held between the holding element 6 and the locking member 7, the holding element 6 and locking member 7 now functioning as one unit.
  • the aforementioned unit is pivoted against the force of the spring assembly 9, so that in the subsequent phase of the cross-country step, namely when the ski boot sole 13 rests on the top of the ski 2, the return is facilitated by the spring assembly 9.
  • the skier wants to get out of the ski binding 1, it is sufficient if he puts the tip of his ski pole into the receiving point 7d of the locking member 7 provided for this purpose and pivots the latter forward against the force of the helical compression spring 8. After the shoulder 7c of the locking member 7 has left the support surface 18 of the front connection area of the ski boot 11, the ski boot 11 can be removed from the ski binding 1 by lifting it up.
  • the invention is not restricted to the exemplary embodiment shown. Further modifications are conceivable without leaving the scope of the scope of protection.
  • the design of the two springs can be different.
  • a plate spring can be used; that from leaf springs
  • Existing spring assembly can be replaced by one or more coil springs or also disc springs, which are supported with their other end on the web of the holding plate.
  • connection area of the ski boot can be designed differently, for example the transverse axis can protrude laterally beyond the connection area, in which case the area of the holding part which has the cutout is formed by two webs on which the transverse axis rests with its two end areas.
