Definitions

  • the invention relates to a ski binding-ski boot combination 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 to 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 rather only during a pivoting process, after a certain pivoting angle, from which the unit consisting of the holding 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. Furthermore, a particularly favorable arrangement of the second spring is achieved.
  • 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 element, which is delimited in its upper area by funnel-shaped inclined surfaces.
  • Another inventive concept is that the second spring with one end portion in the recess of the vertically extending portion of the L-shaped holding element and with its other end portion in the recess of the vertically extending portion of the L-shaped locking member is arranged. In this way, the mutually opposite regions of the holding element and the locking member are used to receive the second spring acting on them.
  • the pivoting movement of the locking member is limited in a simple manner according to the invention in that the base body has an upwardly projecting web, the free end area 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.
  • the locking member has at its rear end region a rearward, projecting approach to the ski boot, the end region of which is closed with an inclined surface, and that the connection region of the ski shoe has a lock which, when the ski shoe is inserted into the binding, is overlapped by the approach.
  • the ski boot associated with the binding is distinguished according to the invention in that the ski boot has two lateral webs in its connection area, in which the transverse axis of the ski boot is mounted, and that the support surfaces of the two webs preferably run flush with the support surface.
  • ski boot is clamped in its position in the binding by means of its lock and transverse axis between the attachment of the locking member and the cutout of the holding element and is supported with its support surface on the support area of the locking member.
  • 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 FIGS. 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. 1.
  • 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 element 6 and a locking member 7 to be described in more detail are pivotably mounted on the axis 5.
  • the holding element 6 has, viewed in elevation. 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 oblique 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, with respect to the axis 5, extends forward to the horizontal section of the L-shaped holding element 6 in a mirror image.
  • 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 boot to be used.
  • the approach 7c serves as a locking lug and is closed at its lower end with an inclined surface 7c.
  • 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, 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 12 essential for the invention is shown in FIGS. 3 to 5. It can be seen that the ski boot 11 has a front support surface 18 which is substantially vertical to the ski boot sole 13 runs. A transverse axis 14 passes through the connection area 12 approximately at the height of the ski boot sole. The transverse axis 14 is held by two webs 15, 16 of the connection area 12 of the ski shoe 11. the transverse axis 14 being in the cutout 6a of the holding element 6 in the inserted state of the ski boot 11 in the ski binding 1.
  • the transverse axis 14 of the ski boot 11 When getting into the ski binding 1 with the ski boot 11, the transverse axis 14 of the ski boot 11 is placed on the inclined surface 6b of the holding element 6, then the ski boot 11 is pressed down, the locking member 7 being supported by the support surface 18 of the ski boot 11 against the action the spring 8, is pivoted before.
  • the locking member 7 In the lower end position, when the transverse axis 14 comes to rest in the cutout 6a of the holding element 6, the locking member 7 pivots by the spring 8, clockwise, the inclined surface 7ci of the extension 7c above the lock 17 of the connection area 12 of the ski boot 11 to Lying comes. Since the ski boot 11 rests with its support surface 18 on the support region 7e 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 the return by the spring assembly 9 is facilitated in the subsequent phase of the cross-country skiing step, namely when the ski shoe sole 13 rests on the upper side of the ski 2 .
  • the skier wants to get out of the ski binding 1, it is sufficient if he places the tip of his ski pole in the receiving point 7b 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 12 of the ski boot 11, the ski boot 11 can be removed from the ski binding 1 by lifting it up.
  • the design of the two springs can be different.
  • a plate spring can be used; the spring assembly consisting of leaf springs can be replaced by one or more coil springs or also plate springs, which are supported with their other end on the web of the holding element.
  • 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 element which has the cutout is formed by two webs on which the transverse axis rests with its two end areas.
