Patent

CA 2381949

A self-spotting apparatus for free-weights (101) provides two cable assemblies (107A, 107B) with one end of each cable assembly attached to a free-weight assembly (115) and the opposite end attached to respective linear weight- support assemblies (123A, 123B) via respective weight-responsive engagement blocks (125A, 125B). Guide rods (127A, 127B) allow vertical motion of the engagement blocks and maintain engagement orientation relative to the support assemblies. The engagement blocks engage the respective support assemblies for static support of the free-weight assembly. Lifting of the substantial weight of the free-weight assembly and activation of disengagement bias is required to disengage the engagement blocks from the respective support assemblies to allow free motion of the free-weight assembly. The apparatus provides self- spotting for barbells (115) and dumbbells (247A).

L'invention concerne un appareil de remise en place automatique d'haltères (101), comprenant deux ensembles de câbles (107A, 107B). Une des extrémités de chaque ensemble de câbles est rattachée à un ensemble (115) d'haltères, l'extrémité opposée étant rattachée à des ensembles linéaires (123A, 123B) de support de poids par l'intermédiaire de blocs de contact (125A, 125B) respectifs. Des tiges de guidage (127A, 127B) permettent aux blocs de contact de se déplacer verticalement, et maintiennent l'orientation de contact par rapport aux ensembles de support. Les blocs de contact viennent en contact avec leurs ensembles de support respectifs afin d'assurer le support statique de l'ensemble d'haltères. L'élévation du poids sensible de l'ensemble d'haltères et l'activation du biais de dégagement sont nécessaires pour dégager les blocs de contact de leurs ensembles de support respectifs, afin de permettre le libre mouvement de l'ensemble d'haltères. L'appareil permet une remise en place automatique des barres à disques (115) et des haltères (247A).
