Definitions

  • a safety ski binding in which a ball is mounted on the ski and engages the socket of ski boot engaging means.
  • a detent recess is provided in the ball and receives a springbacked holding device mounted in the ski boot engaging means.
  • the ski boot engaging means is thereby normally held in a selected position as determined by said detent recess but same can move out of such normal position in any direction permitted by the ball-and-socket relationship upon application of sufficient force thereto.
  • SAFETY SKI BINDING This invention relates to a safety ski binding comprising at least one sole holder engaging the toe or heel of the shoe, a ball head fixed to the ski and having a detent recess which when in position of use is urged by a spring-backed locking means into a ball cup which at least partially surrounds the ball head and is connected to the sole holding part.
  • the locking part is constructed as a locating point which engages a detent recess, the center portion of the recess of which is surrounded by an edge portion in the form of an elliptical cone-shaped shell.
  • the purpose of the present invention is to construct a safety ski binding of the above type which provides a simple construction for the detent recess and the'locking part whereby, however, a greater release force is required for the front release than for the horizontal rotary release.
  • the invention provides that the detent recess is constructed as a constantly curved surface and is positioned between the horizontal and vertical plane starting at the center point of the ball head.
  • the line of spring action of the ball cup which is connected to the sole holding part and is engaged in the detent recess through the locking part, can be directed to the center point of the fixed ball head.
  • the line of spring action can also extend eccentrically with respect to the center point of the fixed ball head, through which an advantageous change of the release force is obtained.
  • the locking part can be a ball and the detent recess can have a ball shape. This results in an economical manufacture of the necessary parts.
  • the locking part can be a ball and the detent recess can be a spherical sector whereby the ball, if necessary, can have a surface contact instead of a line contact.
  • the locking part can also be a cone whereby the detent recess has a conical shape.
  • the relation between the diameter of the ball head and the diameter of the locking part can be about 1:] which results structurally and functionally in favorable dimensions and values.
  • FIG. 1 is a partially sectioned side-elevational view of the safety ski binding of the invention comprising two coacting balls as locking elements;
  • FIG. 2 is a partial cross-sectional view of a further embodiment of the invention comprising a ball and a locating point as locking elements.
  • the safety ski binding according to FIG. 1 is mounted onto the ski and substantially comprises the ball head 2 which is secured to the ski 1, the locking (or detent) part 4 which is constructed as a ball 3, the ball cup 6 which is connected to the sole (shoe) holding part and the spring element 7.
  • the ball head 2 is positioned on a pin 8 and is rigidly connected to the ski 1 through said pin.
  • the ball head 2 includes a detent recess 12 between the horizontal plane 10 from the center point 9 and the vertical plane 1!.
  • Said detent recess 12 is constructed as a constantly curved surface and can have a conical shape.
  • the position of the detent recess between the vertical plane 11 and the horizontal plane 10 does not change the magnitude of the front release force while the magnitude of the rotary release force decreases with an increasing approximation of the detent recess to the vertical plane ll, which means that the release occurs more quickly.
  • the ball 3 engages the detent recess 12 under the pressure of the spring 7.
  • the ball 3 and the spring 7 are guided in a cylindrical section 13 which is connected in one piece to the ball cup 6 which at least partially surrounds the stationary ball head 2.
  • This ball cup 6 is open on the side 14 for reasons of installation and to assure a satisfactory rotation motion.
  • upper side 14 is covered in the upper zone by a metal plate 13 and by a resilient cover means (rubber, plastic or the like) to so that the interior of the safety ski binding is satisfactorily protected against dirt, icing, etc.
  • a resilient cover means rubber, plastic or the like
  • the spring 7 is urged against the ball 3 in the cylindrical section 13 by means of a threaded bolt 17 and permits various adjustment possibilities, suited to the requirements, by adjusting the threaded bolt within the cylindrical section.
  • the direction of the spring action line 18 can extend to the center point 9 of the fixed ball head 2 or can be arranged eccentrically thereto. A change of the release pressure and a further improvement of the relations of the front release with respect to the rotary release is advantageously obtained by means of the eccentric arrangement.
  • the spring action line 18 extends eccentrically to the center point 9 of the fixed ball head and a greater force is required for a front release as a result thereof.
  • the required force is smaller so that the ski binding of the invention can satisfactorilyfulfill the requirements which occur in practice,
  • the safety ski binding of the invention can be released in any direction and thus meets all requirements of different dan gerous occurrences.
  • the ball can slide, except in upward direction for which there is no need, in any desired direction away from the ball cup 6 against the force of the springbacked detent recess 12 about the center point 9 of the stationary ball head 2 and thus can effect a movement away from the stable position. If the stable position, that is, the return capacity of the ball 3 into the detent recess, is exceeded, the ball 3 springs out of the detent recess 12 and release occurs.
  • the balls 2 and 3 can have approximately the same diameter.
  • the amount of the movement before release depends on the size of the detent recess 12 with respect to the locking part 4. If a long movement before release is to be obtained, then the detent recess 12 is enlarged and, for example, a flat conical shape is chosen which is greater than or equals Thus, the contact points of the locking part 4, in the present case of the ball 3, can lie within the detent recess 12 and an enlargement of the movement to the moment of the release is obtained.
  • the lower part of the cylindrical section 113 rests on the holding means 19 and in the present embodiment one steps with the heel of the shoe onto the entry support 20.
  • the pivotable part of the binding isrotated counterclockwise about the center point 9 until the ball 3 engages the detent recess 12 under the action of the spring and the ski boot is held by the sole holding part 5 which grips over the sole.
  • a locating point 21 is provided as a locking part 4 in FlG. 2 instead of the ball 3 which locating point engages the detent recess 12.
  • Said detent recess can have a conical shape so that a surface contact with the locking part is obtained; however. a line contact with the locking part can also be provided through the construction of the detentrecess as a spherical sector.
  • the spring action line 18 can extend to the center point 9 of the stationary ball head or, as illustrated in H0. 2, can be arranged eccentrically thereto. Again, the desired favorable relation of the various release forces during front release and rotary release in the horizontal plane is obtained in a simple manner.
  • the eccentricity of the spring action line 18 may be made adjustable by any convenient means with respect to the center point 9 in the embodiment as illustrated so that a further adjustment of the required release force is obtained (not illustrated).
  • the safety ski binding of the invention is of a simple structure, functions with a high degree of safety and has the capacity of three-dimensional release.
  • a safety ski binding comprising:
  • a ball head fixedly secured to a ski and having a detent recess therein located above a horizontal plane through the center thereof and to one side of a vertical plane through the center thereof;
  • ski boot engaging means having means thereon to engage said ball head and support said ski boot engaging means for swivelable movement, said ski boot engaging means having elongated housing means defining an action line, the longitudinal axis of said action line intersecting said vertical plane at a point radially offset from the center point of said ball head;
  • locking means on said elongated housing means adapted to move along said action line toward and away from said ball head, said locking means, when in a first position being partially received in said recess to lock said ski boot engaging means to said ball head and when in a second position permitting a swiveling movement of said ski boot engaging means relative to said ball head;
  • resilient means adapted to urge said locking means toward said ball head at all times to yieldably resist said swiveling movement of said ski boot engaging means.
  • a safety ski binding according to claim I wherein said elongated housing means has an opening therethrough. the longitudinal axis of which defines said action line which intersects said vertical plane at a point offset from the center point of said ball head;
  • adjustable stop means at one end of said opening adapted for adjustable movement longitudinally of said opening
  • said resilient means comprises a spring positioned within said opening in said elongated housing between said adjustable stop means and said locking means, an adjustment of said adjustable stop means longitudinally of said opening regulating the engagement force between said locking means and said ball head.
  • a safety ski binding according to claim I wherein said locking means is a cone and said detent recess has a conical shape.
