Definitions

  • the invention relates to ski bindings, especially releasable or safety ski bindings.
  • the invention concerns a ski binding for mounting on a ski and which comprises a housing and a release member for retaining the ski boot and which releases against spring action in the event of excessive load or strain.
  • the release of the shoe may be effected manually, or by engaging and pressing down the latch lever with the point of the ski pole, or also in the event of a fall by automatic release.
  • the invention provides in the first place that the housing of the safety device or binding is pivotally connected with the release member or device, and that furthermore the safety binding which is constituted essentially of a release device and a spring is linked to a base plate fastened to the ski or the like, in which connection the two linkage locations are disposed at a distance from one another.
  • the safety binding which is constituted essentially of a release device and a spring is linked to a base plate fastened to the ski or the like, in which connection the two linkage locations are disposed at a distance from one another.
  • the binding can be constructed as a closed unit which is connected with the base plate or with the ski merely by the aforementioned linkage. In the operation or for release, this unit, or its housing, yields in the direction of the force applied to it against the effect of the spring.
  • the base plate serves preferably as a counter-bearing or abutment and sliding surface.
  • FIG. 1 shows a longitudinal section through a first embodiment
  • FIG. 3 is a side view of the release member
  • FIG. 4 is a section along line lV--IV in FIG. 3,
  • FIGS. 5 and 6 are top and side views of a component part
  • FIG. 7 is a longitudinal section of a second embodiment of the invention.
  • FIG. 8 shows the arrangement in accordance with FIG. 7, but after release
  • FIG. 9 is a top view of the embodiment shown in FIGS. 7 and 8.
  • a base plate 2 is threadedly secured to the ski 1 and is adjustable longitudinally of the ski by means of the slots 3, and can be secured in the require-d position by means of the fastening screws 4.
  • the safety binding is linked by means of pivot axis member A1 to the lugs 5 which, for example, extend upwardly from the base plate 2, or from the upper surface of the ski; in this particular embodiment by means of the lateral cheeks 6 (see FIG. 3) of the latch lever which in this example constitutes the release device and encompasses the housing with its checks 6'.
  • This release device 6 is in addition pivotally connected with the housing 8 by way of a pivot axis indicated at A2, in a manner that there is a space between the two pivot axes All and AZ.
  • This system which in principle consists of the release device 6, the housing 8, the bias spring 9, and if need be of further components, is pivotally movable in the manner of a tilting support lever with respect. to the base plate about the axis A1 which extends transversely of the direction of forces, i.e., transversely of the longitudinal extent of the ski.
  • the housing In the operative position in accordance with FIG. 1 (holding of the ski boot) the housing rests at its rearward end upon the base plate, or on an abutment 10 formed in the plate.
  • the abutment may be a plate of plastic material threadedly secured in place.
  • the pivot axis A1 and the abutment 10 may be at approximately the same level.
  • the housing 8 In operating the release device 6, or when a requisite release force occurs at the shoe 11, the housing 8 is pressed against the abutment 10 and simultaneously against the effect of the spring 9, in the direction of the force, i.e., in this case rearwardly sliding longitudinally of the ski.
  • the abutment simultaneously performs the function of a guiding slide.
  • a pin 12 may be provided (see FIGS. 5 and 6) which is non-rotatably secured to the cheeks 6.
  • the pin is provided with lateral bosses 14 which fit into corresponding slots 15 of the lateral checks 6.
  • the bolt projects through the housing 8 and thus serves for securing the same to the release device 6.
  • the bolt is provided with a flat surface 16 that acts upon the spring 9 and which preferably extends obliquely with respect to the bosses 14. A flattened surface for producing this effect could also be provided directly on the release device.
  • the engagement point of the release member with the spring is constituted in the present embodiment by the upper edge 17 of the flattened portion 16. This point of engagement is spaced with respect to the linkage axis A2 so that as the release member is pivotally moved, it engages the spring 9 with a lever effect.
  • the end of the spring 9 which faces the sole latch or retainer 18 is provided for this purpose with an engagement surface, for example, a slip-over sleeve 19 which may slide within a corresponding bore of the housing 8.
  • the other end of the spring 9 is encompassed by an adjusting screw 20 which closes this bore and by means of which the tension of spring 9 may be changed.
  • a shackle 21 is provided for receiving the catch strap 22.
  • the release device lever 6 In order to be able to seize the heel of the shoe 11 with the sole holder or depressor 18, the release device lever 6 has to be pressed downwardly. This is done manually or by inserting the point of the ski pole into the recess 6". As a result, the upper edge 17 of the bolt or the pin 12 presses against the sleeve 19, thus compressing spring 9. Since the release device lever 6 is not only pivotally connected at the housing 8 at a first pivot axis A2 but also at a second pivot axis A1 to the base plate, it moves at the same time pivotally also with respect to the housing about the second pivot axis A1.
  • the housing 8 and the sole holder 18 are displaced rearwardly along a flat are, almost parallel to the surface of the ski, and the shoe can be fitted upon the ski surface.
  • the lever 6 is released, the parts return to the position illustrated in FIG. 1 under the pressure of the spring 9 so that the shoe is securely held.
  • the axis A2 it is advisable to arrange the axis A2 in a manner that, seen in the direction of travel, it is ahead of a vertical line that passes through the axis A1. In other words, the axis A2 is displaced forwardly with respect to the axis A1.
  • the lever 6 is provided on the one hand with sufficiently large rocking area for the releasing, and on the other hand this insures of safe release of the binding in the event of a forward fall.
  • an upwardly directed force is applied to the sole holder which in this arrangement pivots the entire arrangement about axis A1, thus initiating the release, and also imparts a rearwardly directed component of force to the binding.
  • the aforementioned displacement of the axis A2 relative to the sole holder provides that the housing 8, respectively the sole holder 18 which is fastened thereto applies a forwardly and downwardly directed force to the shoe in the closed position which presses the shoe in the desired manner against the surface of the ski.
  • the resilient support of the shoe during normal running operation is obtained in that the sleeve 19 which is under the pressure of spring 9 engages the upper edge 17 of the flattened surface.
  • the arrangement or the setting of the safety binding is chosen in a manner that the aforementioned parts are not yet in the final position when in closed position, but that between the front end of the sleeve 19 and the flat surface 16 there remains a slightly wedge-shaped gap or angle. It is understood, however, that the invention is not limited to this form of construction.
  • the housing By providing such a closed unit, it is furthermore possible to construct the housing to be closed in such a manner that no ice or snow can enter and block the parts, particularly the spring.
  • the housing may have two bores that are arranged at a right angle with respect to each other, of which the bore for receiving the spring 9 is covered for protection against ice by set screw 20, and the bore for receiving the pin or bolt 12 by the lateral cheeks 6'.
  • the two screws 4 are sufiicient.
  • the release moment of rotation which comprises the rotational force applied against the housing and the lever arm A1A2 opposes the resetting release rotation moment which is constituted by the counter-force of the spring 9 and the distance between the location of contact 17 and the axis A2. Accordingly, release will take place in the event of a forward fall when the release moment of rotation becomes greater than the resetting moment of rotation which is set by tensioning the spring.
  • the sole holder or retainer 18 is mounted in the housinb 8 for pivotal movement about the vertical axis 23.
  • it can be held in its position by means of a spring 24, the pressure of which is adjustable.
  • the ball 24 disengages the corresponding recess of the sole holder 18 and thus releases it.
  • a safety head of this type thus also releases in the event of a forward fall, backward fall, and also torsion fall.
  • the sole holder may also be so constructed that during a torsion turn the ski boot must first overcome a deadpoint and correspondingly displaces in this manner the housing 8 in the longitudinal direction.
  • the parts turn about the pivot point A1 which results in raising of the housing 8.
  • two protrusions 25 which are arranged at such a distance from one another that they seize the front edge of the boot sole 11' from both sides are provided.
  • the two protrusions 25 form, together with the axis 23, a three-point bearing support. It is seen that for a torsion fall and swinging of the sole holder about the axis 23 the entire safety binding is displaced longitudinally of the ski until the particular protrusion 25 is enabled to release the edge of the ski sole. With this arrangement even the ball catch 24 would be unnecessary under certain conditions because the ratio of this dead-point latch can be so proportioned that its opposing force corresponds to the release force. One may, however, additionally provide the ball catch 24 especially for the setting of the release force.
  • the safety binding illustrated in FIGS. 1 to 6 can, of course, be utilized for holding the point of the boot, and
  • the binding illustrated in FIGS. 7 to 9 may also be utilized for retaining the heel portion, in which event the proper sole holder must be provided. Therefore, it is furthermore within the scope of the invention that for rationalizing the manufacture and the bearing support only one single safety binding is provided with an interchangeable sole holder whch may then be optionally used as safety head or as What is generally referred to as automatic heel release.
  • Safety binding adapted to be secured to a ski for retaining a ski boot, comprising a release device, a spring and a housing, said release device being pivotally connected with said housing at a first pivot axis, supporting means secured to the ski, said spring being disposed in said housing with one end proximate said release device and the other end biased in said housing to apply pressure against said release device, said housing, said release device and said spring forming an assembly, said assembly being pivotally mounted about a second pivot axis disposed at a distance from said first pivot axis with respect to the longitudinal extent of the ski.
