Exercise machine with adjustable rack out hooks and adjustable counterweighted safety tiers
An exercise machine with an adjustable safety tier and rack out hook system, having: (a) a safety tier attached to and moveable along each of a pair of upwardly-extending guide rods, wherein the safety tier can be rotated to a locked position such that the safety tier latches onto the upwardly-extending support member or rotated to an unlocked position; (b) a counterweight connected to each safety tier; and (c) a rack out hook attached to and moveable along each of the upwardly-extending guide rods, wherein the rack out hook can be rotated to a locked position such that the rack out hook latches onto the upwardly-extending support member or rotated to an unlocked position.
1 . An exercise machine having an adjustable safety tier and rack out hook system, comprising:
a frame comprising:
a pair of upwardly-extending support members, and
a pair of upwardly-extending guide rods, wherein one of the guide rods is positioned next to each of the upwardly-extending support members;
a safety tier attached to and moveable along each of the upwardly-extending guide rods, wherein the safety tier is configured to be rotated to a locked position such that the safety tier latches onto a respective one of the upwardly-extending support members or to an unlocked position such that the safety tier disconnects from the respective upwardly-extending support member;
a counterweight connected to each safety tier; and
a rack out hook attached to and moveable along each of the upwardly-extending guide rods, wherein the rack out hook is configured to be rotated to a locked position such that the rack out hook latches onto a respective one of the upwardly-extending support members or to an unlocked position such that the rack out hook disconnects from the respective upwardly-extending support member and
wherein the safety tiers and rack out hooks each rotate around the upwardly-extending guide rods from their locked to unlocked positions.
2 . The machine of claim 1 , wherein the frame further comprises base supports connected to bottom ends of the upwardly-extending support members.
3 . The machine of claim 2 , wherein the frame further comprises a top support connected to top ends of the upwardly-extending support members.
4 . The machine of claim 3 , further comprising a pair of lifting handles on the top support.
5 . The machine of claim 2 , further comprising a pair of upwardly-extending rear supports connected to the base supports and the top support.
6 . The machine of claim 1 , wherein each of the upwardly-extending support members have a series of grooves thereon, and wherein the safety tiers and the rack out hooks have protrusions thereon that are received into the grooves when the safety tiers and the rack out hooks are in their locked positions.
7 . The machine of claim 6 , wherein the safety tiers and rack out hooks further comprise a wear plate that is positioned against the respective upwardly-extending support member when the safety tiers and rack out hooks are in their locked positions.
8 . The machine of claim 6 , wherein the series of grooves are on a front of the upwardly-extending support members, and the guide roda are positioned behind the upwardly-extending support members.
9 . The machine of claim 1 , wherein the safety tiers and rack out hooks are attached to the upwardly-extending guide rods by slidable bushings.
10 . The machine of claim 1 , wherein the safety tiers and rack out hooks each rotate approximately 20 degrees between their locked and unlocked positions.
11 . The machine of claim 1 , wherein the safety tiers and rack out hooks are moved from their locked to unlocked positions by lifting them and rotating them inwardly.
12 . The machine of claim 1 , wherein each counterweight moves up and down within a respective one of the upwardly-extending support members.
13 . The machine of claim 1 , wherein each safety tier and counterweight are connected by a cable passing within the respective upwardly-extending support member.
