Abstract

A multilink structure provides for a stabilizer system for an expansion section of an expandable structure, such as for a slide-out of a recreational vehicle. The stabilization system can be securely mounted onto either the chassis or the extension track, offering versatility for different configurations. Due to space constraints on the chassis, the stabilizer is engineered to remain horizontally aligned when retracted, maximizing available space. The primary connection point for the multilink stabilizer system is the chassis structure, with the outer wall attached as a secondary support. During deployment, the outer wall ingeniously combines pushing and rotational forces to smoothly extend the stabilizer assemblies outward. Once fully extended, the stabilizer adopts a fully vertical position, providing vital stability and support for the expansion section or slide-out. The stabilization system can eliminate the need for manual adjustment and alignment, thereby offering users a seamless and hassle-free experience.

First claim

What is claimed is:

1 . A stabilization structure for a deployed expansion structure of an expandable structure, comprising:
a multilink stabilizer assembly having a first support beam attached to a main structure at a proximate end of the first support beam, a second support beam having a proximate end pivotable about a vertical axis at a distal end of the first beam, a first push arm and a second push arm, wherein the first and second push arms are operable to move an actuator assembly between a horizontal position, when the expansion structure is in a retracted state, to a vertical position, when the expansion structure is in a fully expanded state.

2 . The stabilization structure of claim 1 , wherein:
a first end of the first push arm is pivotably attached to the first support beam; a second end of the first push arm is interconnected with a first end of the second push arm; and the second end of the second push arm is pivotably attached to an upper end of the actuator assembly.

3 . The stabilization structure of claim 2 , further comprising a push arm adaptor having a base slidably engaged in a channel formed in the second support beam, the push arm adaptor being pivotably attached to the second end of the first push arm about a vertical pivot axis, the push arm adaptor being pivotably attached to the first end of the second push arm about a horizontal pivot axis.

4 . The stabilization structure of claim 1 , wherein the actuator assembly pivots about a horizontal pivot axis between an outer support beam body and an inner support beam body of the second support beam.

5 . The stabilization structure of claim 1 , further comprising a connector extending from the second support beam, the connector attached to an outer wall of the expansion structure.

6 . The stabilization structure of claim 1 , wherein the multilink stabilizer assembly fits into an opening formed in the main structure when the expansion structure is in the retracted state.

7 . The stabilization structure of claim 6 , wherein an outer planar surface of the second support beam is substantially parallel with a plane defined by an outer wall of the expansion structure when the expansion structure is in the retracted state.

8 . The stabilization structure of claim 7 , wherein the outer planar surface of the second support beam is angled from about 20 to about 90 degrees relative to the plane defined by the outer wall of the expansion structure, when the expansion structure is in the fully expanded state.

9 . The stabilization structure of claim 7 , wherein the outer planar surface of the second support beam is angled from about 30 to about 80 degrees relative to the plane defined by the outer wall of the expansion structure, when the expansion structure is in the fully expanded state.

10 . The stabilization structure of claim 1 , wherein first and second ones of the actuator assembly are vertically disposed at opposite corners of the bottom of the outer wall when the expansion structure is in the fully expanded state.

11 . A stabilization structure for a deployed expansion structure of an expandable structure, comprising:
a multilink stabilizer assembly having a first support beam attached to a main structure at a proximate end of the first support beam, a second support beam having a proximate end pivotable about a vertical axis at a distal end of the first beam, a first push arm, a second push arm and a connector, wherein the connector extends from the second support beam to attach to an outer wall of the expansion structure; the first and second push arms are operable to move an actuator assembly between a horizontal position, when the expansion structure is in a retracted state, to a vertical position, when the expansion structure is in a fully expanded state; a first end of the first push arm is pivotably attached to the first support beam; a second end of the first push arm is interconnected with a first end of the second push arm; the second end of the second push arm is pivotably attached to an upper end of the actuator assembly; and the actuator assembly pivots about a horizontal pivot axis between an outer support beam body and an inner support beam body of the second support beam.

12 . The stabilization structure of claim 11 , further comprising a push arm adaptor having a base slidably engaged in a channel formed in the second support beam, the push arm adaptor being pivotably attached to the second end of the first push arm about a vertical pivot axis, the push arm adaptor being pivotably attached to the first end of the second push arm about a horizontal pivot axis.

13 . The stabilization structure of claim 11 , wherein the multilink stabilizer assembly fits into an opening formed in the main structure when the expansion structure is in the retracted state.

14 . The stabilization structure of claim 13 , wherein an outer planar surface of the second support beam is substantially parallel with a plane defined by an outer wall of the expansion structure when the expansion structure is in the retracted state.

15 . The stabilization structure of claim 14 , wherein the outer planar surface of the second support beam is angled from about 30 to about 80 degrees relative to the plane defined by the outer wall of the expansion structure, when the expansion structure is in the fully expanded state.

16 . The stabilization structure of claim 11 , wherein first and second ones of the actuator assembly are vertically disposed at opposite corners of the bottom of the outer wall when the expansion structure is in the fully expanded state.

17 . A stabilization structure for a deployed expansion structure of an expandable structure, comprising:
