Abstract
A centering device for a platform lift which includes a lifting mechanism for moving objects from a first to a second height. The lift mechanism has a base, at least a first and a second set of legs, and a platform. The first and second sets of legs each have first opposite ends pivotally secured to the base and the platform, respectively, and second opposite ends provide with traveling members to cooperate with the platform and base, respectively. The platform has a lower portion including a rail upon which the traveling members of the first set of legs traverse. Between the ends of each of the first set of legs, having the traveling members, and the rail, a centering device is disposed to provide alignment of the traveling members and the rails.
Claims9
1) a lift comprising:
- a lifting mechanism
- for moving objects from a first to a second height, including a base, a first set of legs, a second set of legs, a power module, and a platform;
- the legs each having a proximal end and a distal end;
- the proximal ends of the first set of legs each being secured to the base, and the distal ends each having a traveling member;
- the proximal ends of the second set of legs each being secured to the platform, and the distal ends each having a traveling member;
- the platform having a lower portion including a rail upon which each of the traveling members of the first set of legs traverse;
- and
- a centering device disposed between each of the distal ends of the first set of legs and the corresponding rail to provide alignment of the traveling members with the rails.
7) A centering device for a platform on a lift comprising:
- a lifting mechanism including a base and a set of legs having first ends pivotally secure to the base and having traveling members associated with second ends opposite the first ends, a second set of legs, and traveling members;
- the platform having a lower portion including a rail upon which each of the traveling members of the set of legs traverse;
- and
- a centering device disposed between each of the second ends of the set of legs and the corresponding rail to provide alignment of the traveling members with the rails.
8) A lift comprising:
- a lifting mechanism
- for moving objects from a first to a second height including a base, a combination of legs, a platform, traveling members and a power module;
- the combination of legs including at least a first pair of legs having a first travel end and a first pivot end and including at least a second pair of legs having a second travel end and a second pivot end;
- the first and second travel ends being opposite one another and including a traveling member associated with each of the legs of the first and second pairs of legs at the respective travel ends thereof;
- the first pivot end of the first pair of legs being pivotally attached to the base, and the second pivot end of the second pair of legs being pivotally attached to the platform;
- the platform having a lower portion including rails upon which each of the traveling members of the legs of the first pair of legs traverse;
- and
- a centering device disposed between the rails and the first travel ends of each of the legs of the first pair of legs to provide alignment of the traveling members with the rails.
9) A method for centering a lift, comprising:
- providing a lifting mechanism for moving objects from a first to a second height including a base, a platform, and a combination of legs;
- providing the combination of legs as first and second pairs of legs;
- attaching one end of each of the first pair of legs to the base for pivotal movement;
- attaching one end of each of the second pair of legs to the platform for pivotal movement;
- providing a traveling member on the other end of each of the first pair of legs to traverse respective rails on the platform;
- providing a traveling member on the other end of each of the second pair of legs to traverse the base;
- and
- aligning the traveling members with the rails by disposing a centering device between the first pair of legs and the rails.
