US Patent:

6345855, Feb 12, 2002
Filed:

Dec 20, 1999
Appl. No.:

09/467272
Inventors:

Paul E. Hanser - Tipton IA
Stacy M. Hanser - Davenport IA
Assignee:

HWH Corporation - Moscow IA
International Classification:

B60P 334
US Classification:

296 2614, 296 2613, 296165, 296176, 52 67
Abstract:

A Level Floor Room Extension for expandable and retractable rooms in vehicles employs a subfloor movable from a horizontal stored position beneath the vehicle floor, through an intermediate horizontal position, to an elevated horizontal position, to provide a continuously level floor extending from the interior vehicle floor, over the subfloor, to the slide out room floor.

Filed:

Oct 26, 2001
Appl. No.:

09/682874
Inventors:

Vincent Buls - Wilton IA
Stacy Hanser - Davenport IA
Assignee:

HWH Corporation - Moscow IA
International Classification:

B60P 334
US Classification:

296 2612, 296 2613, 296172, 296173, 296176, 296165
Abstract:

A linkage mechanism provides for the extension and retraction of rooms in recreational vehicles while maximizing the space inside the vehicle. Braced parallel linkage members are applied between a vehicle frame member and an expandable room member. A hydraulic cylinder or other force assist element may be used to drive a slotted glide arm which, in turn, causes the braced parallelogram linkage to shift, thus pulling or pushing the room frame member relative to the vehicle.

Filed:

Jan 15, 2003
Appl. No.:

10/248379
Inventors:

Paul Edmund Hanser - Tipton IA
Stacy Hanser - Davenport IA
Assignee:

HWH Corporation - Moscow IA
International Classification:

B60P 334
US Classification:

296171, 296172, 296175, 296 2612, 296 2614
Abstract:

A push-pull drive chain mechanism and scissors linkage assembly powered by a hydraulic cylinder to affect the coordinated, linear movement of an expandable room in a recreational vehicle. The drive chain moves generally vertically along a first structural member, such as a vehicle frame member, as the hydraulic cylinder extends or retracts to move the expandable room relative to the vehicle frame. The drive chain is pivotally connected at the proper place on the scissors-type linkage assembly, the links that form the scissors extending and crossing for pivotal attachment to a structural member of the vehicle body and a structural member of the expandable room. The drive chain is constructed and guided to provide the required force for opening and closing the scissors assembly.

Filed:

May 18, 2004
Appl. No.:

10/709623
Inventors:

Vincent Buls - Tipton IA, US
Stacy Hanser - Davenport IA, US
Paul Edmund Hanser - Tipton IA, US
Assignee:

HWH Corporation - Moscow IA
International Classification:

B60P003/34
US Classification:

296 2613, 296175
Abstract:

A push-pull drive chain mechanism and scissors linkage assembly and lifter assembly all powered by hydraulic cylinders to affect the coordinated, linear movement of an expandable room in a recreational vehicle. The drive chain moves generally vertically along a first structural member, such as a vehicle frame member, and then horizontally as the hydraulic cylinders extend or retract to move the expandable room relative to the vehicle frame. The lifter assembly assists in raising and lowering the expandable room so that when the room is extended, the floor of the expandable room will be substantially flush with the floor of the vehicle.

US Patent:

7621587, Nov 24, 2009
Filed:

Aug 1, 2007
Appl. No.:

11/832447
Inventors:

Paul E. Hanser - Tipton IA, US
Stacy Hanser - Davenport IA, US
Assignee:

HWH Corporation - Moscow IA
International Classification:

B60R 5/04
US Classification:

296156, 296 2612, 296 2613, 296 371, 296 376
Abstract:

A slidable storage tray adapted to be hydraulically actuated between a retracted position wherein the tray is nested inside a vehicle's storage compartment and an extended position wherein at least a portion of the tray is located outside of the vehicle's storage compartment. The slidable storage tray is dual directional so that it extends from either a first side or a second side of the vehicle. The hydraulic circuit comprises a first hydraulic cylinder and a second hydraulic cylinder. The rod of the first cylinder is attached to the vehicle/storage compartment frame and the rod of the second cylinder is attached to the slidable storage tray. The two hydraulic cylinders are attached together so their barrels cannot move relative to one another. The two hydraulic cylinders are facing the same direction so that their rods both extend in the same direction.

US Patent:

57722706, Jun 30, 1998
Filed:

Aug 4, 1995
Appl. No.:

8/511477
Inventors:

Paul E. Hanser - Tipton IA
Stacy M. Hanser - Davenport IA
Jeffrey W. Hogue - East Moline IL
Assignee:

HWH Corporation - Moscow IA
International Classification:

B60P 334
US Classification:

296 26
Abstract:

An apparatus for extending and retracting one structure with respect to another which utilizes a pivoting mechanism rather than the standard linear mechanisms known in the art. The mechanism further utilizes a torsion bar connected between the distal ends of the actuator for synchronizing the movement of the actuators to prevent binding and twisting. A first embodiment utilizes a flat chain and a pair of circular guides to maintain the torsion bar in a horizontal plane, while a second embodiment of the invention utilizes a four-bar linkage system.

Filed:

Mar 24, 1994
Appl. No.:

8/217322
Inventors:

Stacy M. Hanser - Davenport IA
Paul E. Hanser - Tipton IA
Leroy A. Van Roekel - Wilton IA
International Classification:

F01B 2504
F15B 1122
US Classification:

91171
Abstract:

An apparatus for synchronizing the extension and retraction of linear actuators. A quadrilateral structure is formed by means of the support base, a pair of actuators, and a crossmember, with a sensor positioned so as to detect variations in the shape of the quadrilateral. The sensor functions in cooperation with the actuator control mechanism to vary power to the actuators in response to the changes in shape which occur due to slight variations in actuator speed of movement.
