Abstract
A toggle lever type cross-country ski binding is provided which includes a retaining element pivotally attached to guide arms hingedly supported on a baseplate fixed to a ski. In operation, the retaining element is movable through a dead-center position between a lifted release position and a lowered in-use position with a hook-shaped projection engaging with a boot sole extension to hold the same against longitudinal movement. To facilitate resilient holding of the boot sole, without the need for additional tension springs in the toggle lever arrangement, various embodiments of the invention are disclosed including resilient longitudinal displaceability of the pivot joints between the guide members and the retaining element or between the retaining element and the sole extension.
Claims21
Cross-country ski binding comprising:
- baseplate means fixedly attachable to a ski,
- retaining element means engageable with a ski boot sole extension at a first effective pivot joint to hold said sole extension against longitudinal displacement when said retaining element means is in an in-use skiing position,
- and guide arm means pivotally connected to said retaining element means at a second effective pivot joint and to said baseplate means at a third effective pivot joint such that said guide arm means and retaining element means together form a toggle lever with said retaining element means being movable through a dead-center position between a lifted release position and a lowered in-use position,
- wherein one of said effective second and third pivot joints is resiliently supported or configured in the longitudinal direction of the ski with respect to the other of said second and third pivot joints and the ski or boot sole extension, thereby assuring elastic force retention of said ski boot sole extension.
Cross-country ski binding comprising:
- baseplate means fixedly attachable to a ski,
- retaining element means engageble with a ski boot sole extension at a first effective pivot joint to hold said sole extension against longitudinal displacement when said retaining element means is in an in-use skiing position,
- and guide arm means pivotally connected to said retaining element means at a second effective pivot joint and to said baseplate means at a third effective pivot joint such that said guide arm means and retaining element means together form a toggle lever with said retaining element means being movable through a dead-center position between a lifted release position and a lowered in-use position, wherein the guide arm means exhibits a play in the longitudinal direction of the ski with respect to one of the retaining element means and the baseplate means, and wherein a spring acts on one of a hinge pin connecting the guide arm means with the retaining element means and a hinge pin connecting the guide arm means with the baseplate means to resiliently press the retaining element means forwardly in the longitudinal direction of the ski thereby assuring elastic force retention of said ski boot sole extension.
In a cross-country ski binding of the type comprising a baseplate member that is fixedly attachable to a ski, a retaining member that is configured for retainably engaging a forward sole extension of a ski boot, and a pivot link interconnection between said baseplate member and said retaining member, the improvement wherein said pivot link interconnection is constructed of rigid elements and a resilient element interconnected together so as to experience a resilient play for producing a securement between said retaining member and a forward sole extension that, in use of the ski binding, is resilient in a longitudinal direction relative to the extension secured due to resiliency of said pivot link interconnection in said longitudinal direction created by said resilient play.
In a cross country ski binding of the type comprising a baseplate member that is fixedly attachable to a ski, a retaining member that is configured for retainably engaging a forward sole extension of a ski boot, and a pivot link interconnection between said baseplate member and said retaining member, the improvement wherein said interconnection is constructed to enable longitudinal movements for producing a securement between said retaining member and a forward sole extension that in an in-use position of the ski binding, is resilient in a longitudinal direction relative to the extension secured, and wherein said construction of the interconnection enabling longitudinal movements comprises guide arm means, a first hinge pin for connecting said guide means to said base plate member, a second hinge pin for connecting said guide arm means to said retaining member, said hinge pins being mounted for enabling relative displacement therebetween, and spring means for applying a biasing force acting to control said relative displacement.
