APPARATUS FOR POSITIONING A COMPONENT OF AN EXERCISE DEVICE

摘要

An exercise device including at least one positionable component configured to be positioned by a user. The exercise device includes a frame to which a collar is mounted. The positionable component includes a member that is slidably received within the collar and may be positioned by sliding the member to a selected position. A locking assembly is coupled to the collar and is operable to lock the member in a selected position within the collar, to release the member from the locked position, and when released, to allow the member to slide within the collar. The locking assembly includes a cam pivotably mounted to the collar and a cam follower assembly selectively biased by the cam against a portion of the member disposed inside the collar. The locking assembly also includes a pair of engagement members disposed inside the collar opposite the cam against which the cam biases the member.

主权项

1. A locking assembly comprising:
an adjustably moveable elongated member having a cross-section with a first end portion opposite a second end portion, each end portion being adjacent to a first side portion and an opposing second side portion; a collar having an interior channel defined by a sidewall and a through-hole formed in the sidewall, wherein the elongated member is slidlingly received within the interior channel; a cam pivotally coupled to the collar and configured to pivot between a locked position and an unlocked position; and a cam follower positioned between the cam and the second end portion of the elongated member, the cam follower configured to be biased by the cam, wherein when the cam is pivoted into the locked position, the cam biases the cam follower toward the second end portion of the elongated member to apply a locking force to one or more of the first side portion, the second side portion, and the second end portion, thereby preventing the elongated member from adjustably moving along a path defined by the interior channel.
