Abstract

The invention relates to a weightlifting device (1) comprising a longitudinally extending bar (10) comprising at least one load-bearing section (30) adapted to receive one or more free counterweights (100), the free counterweights (100) The weight includes an opening (101) adapted to surround the weight bearing section. The load-bearing section includes an end stop (31) for one or more free counterweights at a first end (32) of the load-bearing section, an opposite second end (11) of the load-bearing section A recess (12) at or near the free weight, and a free weight locking member (40) for locking the free weight and preventing the free weight from accidentally falling from the second end. The free weight locking member is movable in the longitudinal direction (L) of the load-bearing section between the recess and at least one free weight locking position (33) between the recess and the end stop. The free weight locking member is also movable in a second direction at the recess between a sunken position, a position where the free weight locking member is fully or at least mostly sunk into the recess, and a raised position. The raised position is a position in which the free weight locking member is raised relative to the sunken position and extends at least partially out of the recess.

Description

technical field [0001] The present invention relates to a weight lifting device, such as a barbell or dumbbell. Background technique [0002] A barbell weightlifting set typically consists of a bar and discs of varying weights with a central hole to allow the disc to slide onto the end of the bar where it is temporarily held in place by clamps. position, where the counterweight is secured in various ways (for example using Z-screws, torsion springs or by clamping). [0003] Safety is of paramount concern when handling free weights (those weights that are not permanently attached to a barbell or other weightlifting device), because individual weights may fall on the user and free weights The system is often used with heavy weight loads for bodybuilding and similar activities. Issues such as slippage of the retaining clips can lead to dangerous weight shifts. Therefore, the free weight must be properly secured to the barbell. [0004] Many efforts have been made to improve...
