Link for a linear actuator

1. A link for a chain which is used in a linear actuator, the link comprising:

a base member;

a plate pivotably mounted on the base member, an arm extending from the plate and a first connecting means being disposed on a distal end of the arm to connect the link with a first adjacent link, the plate having a projection for releasably engaging a second adjacent link; and

a second connecting means disposed on the base member to connect the link with the second adjacent link.

2. The link as claimed in claim 1 wherein the first connecting means is a pin, the pin being non-perpendicular to a longitudinal axis of the link.

3. The link as claimed in claim 1 wherein the second connecting means is an aperture for receiving a pin of the second adjacent link.

4. The link as claimed in claim 1 further including a side wall extending along a side of the base member wherein the side wall has an opening therein.

5. The link as claimed in claim 1 further including a side wall extending along a side of the base member wherein the side wall extends beyond an end of the base member and a pin is disposed on a portion of the side wall which extends beyond the end of the base member.

6. A chain for a linear actuator comprising:

a first link having a base member, a pair of opposed side walls extending along sides of the base member of the first link, a first one of the side walls extending beyond an end of the base member of the first link and a connecting means disposed on a portion of the first one of the side walls extending beyond the end of the base member of the first link, a second one of the side walls having an opening therein, an arm extending from the base member of the first link and a connecting means disposed on a distal end of the arm; and

a second link having a base member, a connecting means disposed on the base member of the second link, a second connecting means disposed on the base member of the second link, and a plate pivotably mounted on the base member of the second link, the plate having a projection for releasably engaging the opening in the second one of the walls of the first;

wherein the connecting means disposed on the portion of the first one of the side walls extending beyond the end of the base member of the first link engages the first connecting means disposed on the base member of the second link, and the connecting means disposed on the arm extending from the base member of the first link engages the second connecting means disposed on the base member of the second link.

7. A chain for a linear actuator comprising:

a first link having a base member, a pair of opposed side walls extending along sides of the base member of the first link, a first one of the side walls extending beyond an end of the base member of the first link and a pin disposed on a portion of the first one of the side walls extending beyond the end of the base member of the first link, a second one of the side walls having an opening therein, an arm extending from the base member of the first link and a pin disposed on a distal end of the arm; and

a second link having a base member, a first aperture in the base member of the second link, a second aperture in the base member of the second link, and a plate pivotably mounted on the base member of the second link, the plate having a projection for releasably engaging the opening in the second one of the walls of the first;

wherein the pin disposed on the portion of the first one of the side walls extending beyond the end of the base member of the first link engages the first aperture in the base member of the second link, and the pin disposed on the arm extending from the base member of the first link engages the second aperture in the base member of the second link.
