Abstract: A monolift assembly includes a carriage assembly configured to be releasably secured to a post of a rack for weightlifting equipment. A pivoting piece is pivotally connected to the carriage assembly and has a hook at a first end thereof and a counterweight at a second end thereof. The pivoting piece includes a central plate, a first exterior plate abutting a first side of the central plate and a second exterior plate abutting a second side of the central plate.

Abstract: An adjustable carriage assembly includes a carriage defining a passage configured to receive a frame member therethrough such that the carriage is moveable along the frame member, and a locking structure configured for engaging the frame member to lock the carriage in position relative to the frame member. The locking structure includes a main pin and an auxiliary pin connected to the carriage that are each moveable between a locked position, where the respective pin extends into the passage and is configured to engage the frame member to lock the carriage in position, and an unlocked position, where the respective pin is retracted from the passage and is configured to disengage from the frame member. The carriage may also include a first portion and a second portion, where a space is defined between the first and second portions, and the second portion is adjustable with respect to the first portion.

Abstract: A weightlifting apparatus, which may be in the form of a dip apparatus, includes a mounting portion for attachment to a vertical post, an arm structure extending laterally, and a connecting member extending longitudinally to connect the mounting portion to the arm structure to form a fixed joint, with a brace member to engage the connecting member and the arm structure to reinforce the fixed joint. The brace member has a top surface engaging a bottom wall of the connecting member and a bottom surface of the arm structure, with a leg extending from the top surface. The leg has an upright portion extending upward from the top surface and through a slot in the bottom wall of the connecting member into a central cavity, and a protruding portion extending forward from the upright portion within the central cavity to engage the rear wall of the arm structure.

Abstract: A weightlifting apparatus includes a base for connection to a weight rack, and a first arm and a second arm extending outward on opposite lateral sides. The first arm has a mounting hole extending inward from the front side of the first arm and a plurality of positioning holes around the first mounting hole. A handle is adjustably connectable to the first arm to extend outward from the first arm and includes a connector and a grip member extending outward from the connector. The connector has a shaft extending away from the grip member and a projection alongside the shaft, and the handle is adjustably connectable to the first arm by the shaft being received in the mounting hole. The projection can be received in any of the positioning holes to mount the handle in a plurality of different rotational positions, in which the grip member is oriented differently.

Abstract: An adjustable carriage assembly includes a carriage defining a passage configured to receive a frame member therethrough such that the carriage is moveable along the frame member, a plurality of rollers rotatably connected to the carriage configured to engage the frame member, a connection structure at a front of the carriage for pivotable connection to an articulating implement, and a releasable pin mounted on the carriage at a rear of the carriage. The releasable pin is moveable by axial translation between a locked position and an unlocked position, to selectively extend into the passage to be received in a hole in the frame member to lock the carriage in position or allow movement of the carriage. The carriage has a key hole adjacent to the connection structure, and a key is configured to be removably received in the key hole to lock the articulating implement against articulating movement.
