Definitions

  • the present invention relates to safety bindings for skis. More in particular, the invention concerns safety bindings which are provided with means which effect release of the foot in the event of a forward fall, as well as with lateral or torsion falls which is actuated by the sole retainer against the effect of a spring and in which connection the forward fall release is effected by the longitudinal displacement of a pressure element.
  • the release is so arranged that in the event of torsion falls the pressure member is pivotable about an axis that extends longitudinally of the ski, whereby the point of contact of the force applied by the pressure member against the boot is outside of the aforementioned axis.
  • the sole retainer or boot latch is provided directly on the pressure member or an offset or crank shaped portion of this component.
  • the sole holder Inasmuch as the sole holder is swung to the side, as well as upwardly in the event of a torsion release, although it should maintain its horizontal position, it must be pivotally disposed on the pressure member.
  • This pivotal mounting means for example a rivet, involves the disadvantage that the sole retainer is inevitably rocked with respect to the pressure member, so that as a rule it must first be manually moved into horizontal position before the ski boot can be inserted.
  • the rotary or rivet connection of the sole retainer with the pressure member must be somewhat loose for the aforementioned reasons, while a rigid, stable mounting of the sole holder is desirable.
  • the principles of applicants earlier disclosure are to be maintained, the loose or rotatable joining of the sole holder is to be avoided.
  • the invention provides for use of this type of binding also with automatic heel release means that engage the heel of the ski boot.
  • part of the binding which is provided with the release mechanism and the pressure member are encompassed by a housing or casing which is connected with the part or end of the pressure member that is disposed away from the pivot axis for pivotal or rotatable movement, and also in a manner to be carried along, that furthermore between the binding part and the housing a connection is provided which makes possible swinging of the housing at least horizontally, and that the sole retainer is mounted firmly on the housing.
  • the sole retainer is either formed as unitary part of the housing, for example it may be cast as a unit therewith, or by Patented Sept. 16, 1969 injection molding in plastic form, or it may be mounted rigidly on the housing by means of a threaded connection, or the like.
  • the aforementioned shortcomings of a loose or pivotable mounting of the sole 5 retainer or holder are avoided.
  • the aforementioned binding component, including the projecting end of the pressure member, is fully enclosed by the housing which provides the further advantage that the release mechanism is also protected against the effect of snow and ice.
  • FIG. 1 shows a longitudinal section of a first embodiment taken along the line I-I of FIG. 2,
  • FIG. 1a is a partial view showing a modification of the connection of the pressure member on the housing
  • FIG. 2 is a cross-section taken along line II-II in FIG. 1,
  • FIG. 3 is a top view of a further embodiment of the invention, where the upper part of the housing has been omitted,
  • FIG. 4 is a partial front view of the sole holder of the embodiment in accordance with FIG. 3, and
  • FIG. 5 is a sectional view taken along line V--V in FIG. 3.
  • a binding component 2 which incorporates the release mechanism is threaded onto the ski 1 which mechanism has a pressure member 3 with an offset crank-like end 3' that projects from the housing of the binding component 2.
  • a housing 4 which is pivotally or rotatably connected with the crank or olfset end 3 of the pressure member 3. Furthermore, the housing is also pivotally connected with the binding component 2 or the casing thereof.
  • the offset or crank section 3' for this purpose may have a further projection, a stud or a further offset or crank portion 3", and engage therewith a support or bearing configuration in the interior of the housing.
  • This pressure member 3 with its crank portions 3', 3" may be produced by bending a piece of wire of sufficient strength.
  • a bore 5 (see FIGS. 1 and 2) may serve as the bearing configuration.
  • the housing 4 may be provided with pins 6 defining lateral pivot axles, which are slidably guided in horizontal slots 7 or the like provided in the binding component 2 or in its casing.
  • the guide slot means may also be provided in the housing and the slidable lateral pivot axles or pins in the binding component 2 or in the casing thereof.
  • the housing 4 can be displaced or is slidable longitudinally of the ski in the event of a forward fall, and in the event of a torsion or lateral fall it is pivotally movable in a horizontal plane (see arrows in FIG. 2) and in that event is also pivotally movable about the axis of the pins 6, while the housing rises and moves also in accordance with the crank portion 3".
  • the support on the inside of the housing may also be in the form of a vertical slot 9, as indicated in dot and dash lines in FIG. 1.
  • the crank portions 3', 3" can move upwardly in this slot so that the housing 4 is not raised at its end that supports the sole retainer 8.
  • the connection 6, 7 may be such that it merely permits a displacement and pivotal movement of the housing 4 in a horizontal plane.
  • this binding is used on an automatic heel release, it is advisable to provide an inclined or oblique surface 8' on the top of the sole retainer or rollers on the boot latch or sole retainer (not illustrated). In this manner it is readily possible to press the heel of the ski boot from the top into the binding, whereby the housing 4 moves aside longitudinally of the ski against the effect of the pressure spring in the binding component 2.
  • the sliding of the ski boot out of the binding in the event of a forward or torsion fall may also be facilitated by a suitable oblique surface on the sole retainer or by slide rollers.
  • FIGS. 1 and 2 also makes it possible to construct the casing of the binding component 2 in two parts, in which event the hrizontally extending parting plane coincides with the center axis of the pressure member. This facilitates the production and the assembly in that the pressure member is first placed in the corresponding support of the bottom part, and thereupon the upper part can be placed on top and connected with the lower part (not illustrated).
  • FIG. 3 illustrates schematically in a top view a further embodiment with two pressure members 10, 11 constructed in accordance with the teaching of US. Patent No. 3,194,573, which are disposed symmetrically and parallel with respect to the center line 12.
  • the housing G is shown with a cut-out A in order to expose the pressure members.
  • a sole retainer 13, 14 is securely fastened to each of these pressure members.
  • the boot latch is adjustable in height in that toothed interengaging surfaces are provided between the offset portion 18 of the pressure member which is provided with a guiding slot 15 through which extends a screw 16, whereby the boot latch may be secured in position.
  • This form of construction may also be used in combination with the housing shown in FIGS. 1 and 2.
  • This type of binding may also be used as an automatic heel binding which is provided with the aforementioned oblique surfaces or rollers.
  • the ski boot with this dual arrangement of the pressure members may be especially easily inserted if the upper surfaces of the sole retainer are not only inclined forwardly but also in the direction of the center axis. In this manner the pressure members move aside as the ski boot is pressed in not only in the longitudinal direction of the ski but also laterally.
  • Safety binding for skis of the type including release means having a spring biased pressure member operative to release the boot, which release means during a forward fall is actuated by the boot latch moving said pressure member longitudinally of the ski against the pressure of a biasing spring and during a torsion fall moving said pressure member pivotally about an axis extending longitudinally of the ski, said pressure member extending from said release means and having an offset crank portion, a housing encasing said release means and said crank portion and having an interior bearing configuration for engagement by said crank portion, said housing including a boot latch on the exterior thereof proximate said bearing configuration, and means defining slidable, lateral pivot axes extending between the walls of said housing and said release means proximate the end of the housing and of the release means remote from said bearing configuration permitting horizontal pivotal movement of said housing.
  • Safety binding for skis of the type including heel release means including a spring biased pressure member operative to release the boot, which release means during a forward fall is actuated by the boot latch moving said pressure member longitudinally of the ski against the pressure of a biasing spring and during a torsion fall moving said pressure member pivotally about an axis extending longitudinally of the ski, said binding comprising a pair of release means including pressure members disposed parallel to the center axis of the binding and a separate boot latch mounted on a laterally etxending arm endwise of each pressure member.
