Filed:

Nov 19, 1999

Appl. No.:

09/443357

Inventors:

John S. Lanphear - Lawrence MI 49064

International Classification:

A47B 900

US Classification:

108147, 248631

Abstract:

An adjustable height table includes a base frame, a slider frame assembly, a generally planar support surface and a lifting mechanism. The main portion of the base frame is formed by welding three tubular components to form an H-shape. Each of the end portions of the H-shape include a mounting to support a swiveling locking castor. Above each castor there extends from the H-shaped main portion, a vertically extending tubular post. The slider frame assembly also includes an H-shaped main portion formed of three tubular members. Four vertically extending hollow tubular column members are attached to the H-frame so that they may telescopingly engage the four vertically extending posts of the base frame. A generally planar support surface is attached to the top of the four vertically extending columns located on the slider frame. Located between the central tube of the H portion of the base frame and central tube of the slider frame assembly, there is located a lifting mechanism, preferably a hydraulic jack.

Located between the central tube of the H portion of the base frame and central tube of the slider frame assembly, there is located a lifting mechanism, preferably a hydraulic jack. This jack can be actuated by a pedal mechanism to lift the slider frame assembly relative to the base frame. A second pedal is provided in the lifting mechanism to have the slider frame lower at a controlled rate of descent. Additionally an anti-sway bar is provided to prevent the lifting pump pedal from swaying side to side when in use.

Abstract:

A shelving system and its method of formation. The shelving system comprises a shelf including a support plate, a front edge lip connected to a front portion of the support plate, and a back support edge connected to a back portion of the support plate. The back support edge has an elongated slot. A divider is mounted on the support plate and includes a main portion having a first end and a second end, with a first tab attached to the main portion at the first end and engaging a slit in the front edge lip and a second tab attached to the main portion at the second end, the second tab being provided with a flange, said flange being formed with a hole. A fastener passes through the hole in the flange and the elongated slot in the back support edge to adjustably secure the divider to the shelf.

International Classification:

B66F 11/04

Abstract:

A low-profile adjustable height operator platform includes a low-profile frame, which includes a plurality of struts, and one or more kick plates. The one or more kick plates flank the perimeter of the low-profile frame, acting to structurally support the low-profile so that the platform can achieve a low profile without sacrificing its holding capacity. The low profile of the platform (e.g., being as low as two inches from the ground surface) enables the platform to accommodate and support operators of a variety of heights.

Abstract:

An adjustable height cart height adjustable cart includes a frame extending in a longitudinal direction from a front end of the cart to a rear end of the cart. The frame includes a base provided with casters and a height adjustable frame connected to the base. The height adjustable frame is configured to be raised or lowered relative to the base. The height adjustable frame includes a lower shelf and an upper shelf. The upper shelf has an opening for loading and unloading items onto the cart. A handle is connected to the base at the rear end. A lower tote is slidably mounted on the lower shelf so as to move in a lateral direction. A top tote is slidably mounted on the upper shelf so as to move in the longitudinal direction forward and backward to enable loading of the lower tote through the opening.

International Classification:

A47B 13/08
A47B 13/02
A47B 9/00

Abstract:

A height-adjustable table includes a first tabletop and a second tabletop. A first height adjustment mechanism is configured to vertically shift the first tabletop relative to a support surface on which the table is supported. A second height adjustment mechanism is configured to vertically shift the second tabletop relative to the support surface. The table also includes a base in direct contact with the support surface. Each of the first and second height adjustment mechanisms is directly coupled to the base.

Abstract:

An adjustable staircase includes an upper stair, a lower stair, a first bar and a second bar. The vertical distance between the upper stair and the lower stair is adjustable. Also, each bar is coupled to each of the upper and lower stairs, and the first bar is configured to function as a guard. As a result, the first bar blocks a pinch point between the first and second bars.
