Self contained adjustable support assemblies to support, raise, and lower a mobile living facility with respect to both a vehicle and the ground

Claim 2

Adjustable support assemblies to support, raise and lower a covered space facility with respect to both a vehicle and the ground, each assembly comprising: a. a supporting leg; b. a guide in which the supporting leg moves; c. means to interlock the supporting leg to the guide at selective effective heights of the supporting leg; and d. means, to receive a self contained hydraulic jacking unit positioned between the guide and the supporting leg, whereby, upon release of the interlock means, a hydraulic jacking unit is moved through it operating stroke to change the effective height of the supporting leg, comprising a pin securable to a base of the hydraulic jacking unit, several spaced pin receivers in the supporting leg to receive the pin when it is secured to the hydraulic jacking unit, a receiver secured to the guide into which top portions of the hydraulic jacking unit may be inserted.

Claim 3

Adjustable support assemblies, as claimed in claim 1, wherein each assembly also comprises an attachment structure to be secured to a covered space facility to distribute loads transmitted from the guide.

Claim 4

Adjustable support assemblies, as claimed in claim 2, wherein multiple connection means are used between the attachment structure and the guide, each comprising, overlapping horizontally extending tabs with central openings, arranged in pairs and joined respectively to the attachment structure and guide, and removable fastener assemblies insertable through the central openings of the tab and then secured to hold the extending tabs together and to transmit the supporting loads between the covered space facility and the guide.

Claim 5

An adjustable support assembly to be secured to the corner structure of a camper dwelling, and operated in sequence with other like adjustable support assemblies so secured to raise and to lower a camper dwelling with respect to a pickup truck and then to maintain the relative position selected, comprising: a. a supporting leg having a foot for load distributing ground contact and a body for relative movement with respect to a guiding member, the body having spaced receiving structures to receive a locking member and to receive a hydraulic jacking member; b. a guiding member to receive the supporting leg for relative movement and having a receiving structure to receive a locking member and a receiving structure to receive a hydraulic jacking member, and having fastener connection structures utilized when the adjustable support assembly is secured to corner structure of a camper dwelling; c. a removable locking member for interlocking the body of the supporting leg to the guiding member at selective effective load carrying heights as the removable locking member is inserted through receiving structure on the guiding member and through a selected spaced receiving structure of the body of the supporting leg while a hydraulic jacking member is supporting the load, and thereafter upon complete insertion of the removable locking member, the hydraulic jacking member is removed and prepared for making another elevational changE; and d. a removable self contained hydraulic jacking unit having a projecting means secured to its base to be selectively and removably located in one of the several receiving structures of the body of the supporting leg depending on the height adjustment to be made, and also the top of the hydraulic jacking unit to be located in a receiving structure of the guiding member, and thereafter, the hydraulic jacking unit is effectively operated to raise and to lower the camper dwelling with respect to a pick up truck, and, when no longer needed, to be removed during rapid adjustments of the body of the supporting leg relative to the guiding member when no camper dwelling load is being supported such as when the camper dwelling is securely in place on a pick up truck.

Claim 6

An adjustable support assembly to be secured to the corner structure of a camper dwelling, and operated in sequence with other like adjustable support assemblies so secured to raise and to lower a camper dwelling with respect to a pickup truck and then to maintain the relative position selected, comprising: a. a supporting leg having a foot for load distributing ground contact and a body for relative movement with respect to a guiding member, the body having spaced receiving structures to receive a locking member and to receive a hydraulic jacking member; b. a guiding member to receive the supporting leg for relative movement and having a receiving structure to receive a locking member and a receiving structure to receive a hydraulic jacking member, and having fastener connection structures utilized when the adjustable support assembly is secured to corner structure of a camper dwelling; c. a removable locking member for interlocking the body of the supporting leg to the guiding member at selective effective load carrying heights as the removable locking member is inserted through receiving structure on the guiding member and through a selected spaced receiving structure of the body of the supporting leg while a hydraulic jacking member is supporting the load, and thereafter upon complete insertion of the removable locking member, the hydraulic jacking member is removed and prepared for making another elevational changE; and d. a removable self contained hydraulic jacking unit having a projecting means secured to its base to be selectively and removably located in one of the several receiving structures of the body of the supporting leg depending on the height adjustment to be made, and also the top of the hydraulic jacking unit to be located in a receiving structure of the guiding member, and thereafter, the hydraulic jacking unit is effectively operated to raise and to lower the camper dwelling with respect to a pick up truck, and, when no longer needed, to be removed during rapid adjustments of the body of the supporting leg relative to the guiding member when no camper dwelling load is being supported such as when the camper dwelling is securely in place on a pick up truck.
