Ski Binding Toe Piece Independent Wing Pivoting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toe piece designs for binding boots to gliding boards often experience kinematic disruptions and sizing/assembly challenges due to the eccentric pins and sliding connecting pieces, leading to potential blockages and malfunctions in the lateral release mechanism.
Innovation Solution
A toe piece design featuring a chassis with two wings that pivot independently, utilizing a side release mechanism with a connecting element and elastic means to ensure only the stressed wing pivots, allowing for direct force transmission and preventing automatic opening of both wings, thus enhancing control and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vertical pins are embedded in the wings and a connecting piece slides longitudinally to modify the release range position, then the angular release interval can be shifted, but this introduces kinematic disruptions, potential blockages, and malfunctions in the wing rotation mechanism
Solution Approach 1:
The invention divides the adjustment function into two independent parts: (1) a fixed bearing surface on the chassis that defines the release range position, and (2) an adjustable stop element that can be repositioned along the chassis to modify the release threshold. This segmentation eliminates the need for sliding connecting pieces linked to wing pins, thereby preventing kinematic disruptions while maintaining adjustability.
Solution Approach 2:
The invention extracts the problematic connecting piece mechanism that links the sliding element to the wing pins. Instead, it uses a simplified stop element that acts independently on the wings through a fixed bearing surface, removing the source of kinematic disruptions and potential blockages while preserving the adjustment capability.
2Adaptability or versatility
If a sliding connecting piece is used to adjust the release range position, then the mechanism is adaptable, but the structure becomes more complex with additional constraints in dimensioning and assembly
Solution Approach 1:
The invention segments the adjustment mechanism into a fixed bearing surface and a separate adjustable stop element. This eliminates the need for a sliding connecting piece with multiple bores and pins, significantly simplifying the overall structure while maintaining the ability to adjust the release range position.
Solution Approach 2:
The invention removes the complex sliding connecting piece assembly from the design. The simplified stop element directly engages with the fixed bearing surface, eliminating unnecessary components and reducing dimensional and assembly constraints.
3Adaptability or versatility
If both wings are connected through a sliding mechanism, then the release range can be adjusted, but control during small pivot movements is reduced and force transmission is less direct
Solution Approach 1:
The invention segments the wing support system so that each wing rests independently on the fixed bearing surface through its own vertical pin. The adjustable stop element acts on both wings independently. This eliminates the sliding connection between wings, providing direct force transmission and maintaining control during small pivot movements while preserving adjustability.

AI summary
Front stop (1) of a binding of a boot (8) on a ski board (7) comprising: - a frame (3); - two wings (21, 22), each wing pivoting relative to the frame around a vertical axis of rotation (Z211, Z221) and supporting a lateral interface surface (216, 226) adapted to come into contact with a front part of a boot when the front stop is in a downhill configuration; - a lateral release mechanism (4) comprising: o a connecting element (43); ∘ a first elastic means (42) of which a first end (421) is connected to the connecting element; o a body (41) against which a second end (422) of the first elastic means bears, the body (41) being movable relative to the frame (3);- an adjustment mechanism (5) acting on the wings (21, 22) in order to position them alternately in a first configuration in which each lateral interface surface (216, 226) is in contact with the shoe or in a second configuration in which each lateral interface surface is away from the shoe, for the same positioning of the shoe relative to the front stop (1); The front stop is characterized in that each wing (21, 22) includes an actuating member (214, 224) intended, when the wing is opened, to cooperate with a projection (4313) of the connecting element (43) so as to cause the translation of the connecting element when the wing pivots in one direction, this translation not causing the rotation of the other wing.
