Energy absorbing weight bar support assemblies for exercise equipment
A weight bar support assembly for safely supporting a weight bar on exercise equipment in the event the user cannot return the weight bar to its original position includes an attachment bracket and a weight support member forming a catch arm which is selectively engaged with and moved away from an upright of the exercise equipment. An energy absorbing arrangement is incorporated within either the attachment bracket or the weight support member, and is configured to cushion forces transmitted to the upright upon contact of the weight bar with the weight support member to prevent deformation and/or damage of the exercise equipment.
1. A weight bar support assembly for supporting a weight bar on exercise equipment having an upright formed with a receiving arrangement, the weight bar support assembly comprising:
a catch arm having an attachment bracket and a weight support member, and
an energy absorbing arrangement configured for cushioning a force transmitted to the upright upon contact of the weight bar with the weight support member, wherein the weight bar support assembly is further arranged so that:
the attachment bracket being configured to be engaged with the upright, the attachment bracket including a front wall, a first side wall extending rearwardly from one side of the front wall, a rear wall joined to the first side wall and a second side wall extending rearwardly from another side of the front wall and disconnected from the rear wall, the first side wall being provided with an engagement structure which is slidably and rotatably received within a set of aligned apertures of the receiving arrangement formed in the upright for maintaining the attachment bracket in one desired setting on the upright;
the weight support member extending forwardly from the front wall and configured for supporting the weight bar on the exercise equipment when the engagement structure is received in the aligned apertures; and
the energy absorbing arrangement being incorporated within the attachment bracket, the energy absorbing arrangement including a first cushioning pad provided on an inside surface of the front wall, and a second cushioning pad provided on an inside surface of the rear wall.
2. The weight bar support assembly of claim 1 , wherein the catch arm is configured to allow for a rotational degree of freedom about a pivot axis.
3. The weight bar support assembly of claim 1 , wherein the attachment bracket is configured to be selectively reengaged with the upright upon engagement of the engagement structure with the receiving arrangement at a different desired setting.
4. The weight bar support assembly of claim 1 , wherein the engagement structure is a pin structure which extends perpendicularly from the attachment bracket.
5. The weight bar support assembly of claim 1 , wherein the energy absorbing arrangement is comprised of an elastomer material.
6. The weight bar support assembly of claim 1 , wherein the engagement structure is a cylindrical member extending perpendicularly from the first side wall through the receiving arrangement, which comprises a pair of aligned apertures formed in the upright.
7. The weight bar support assembly of claim 1 , wherein said cushioning pads are provided with recesses that are configured to distribute prevailing forces towards outer edges of the cushioning pads which overlap with outer edges of an upright front face and an upright rear face that are more capable of supporting the forces.
8. The weight bar support assembly of claim 1 , wherein the catch arm is configured to be engaged with and moved apart from the upright by a tilting motion and a lateral motion of the catch arm relative to the upright.
