Appl. No.:

5/651342

Inventors:

Kenneth A. MacDonald - Canton MA

F16M 1124

US Classification:

312255

Abstract:

Panel legs are provided to support one or more connected cabinets in a row and to raise and lower the cabinet to a pre-selected height. Each leg is relatively thin and is comprised of a fixed, lower frame adapted to rest on the floor and a moveable upper portion connected to the cabinet. The moveable upper portion is raised and lowered with respect to the fixed lower portion by means of a lever pivoted at one end to the fixed frame and at the other end adapted to be set into any one of a number of vertically spaced notches formed in a fixed vertical post forming part of the fixed leg section. The lever connects to the moveable upper portion of the leg and, by operation of the lever, the upper portion of the leg, together with any cabinets attached thereto, will be raised or lowered to a selected height. The working mechanism is contained within the leg and is normally hidden from view by means of a removable front panel. A reversible connecting plate is attached to the rear part of the fixed frame portion, extending through the rear of the moveable portion for attachment to the wall behind the cabinets.

US Classification:

312258

Abstract:

A cabinet of the sort used as a vanity, or the like, is molded in several components connected in articulated relation for shipment in a flat, folded condition yet readily erected for installation. The components include a front panel formed with integral hinges connected to cooperating integral hinges formed on a pair of side panels adapted to fold over against one another and the front panel when the cabinet is in a collapsed position. A pair of shelves is provided, each with integral hinge pins pivotally engaging the front and side panels by sockets formed between the side panels and the front panel, both shelves being foldable against the front panel when collapsed. A back panel is provided for closing the rear of the cabinet when erected and means are provided for re-inforcing and supporting the various components from damage during shipment.

Abstract:

An autonomous transport robot for transporting a payload is provided and includes a frame with an integral payload support, a transfer arm connected to the frame for autonomous transfer of payload to and from the frame, and a drive section with at least a pair of traction drive wheels astride the drive section, the drive section being connected to the frame. The at least the pair of traction drive wheels have a fully independent suspension coupling each traction drive wheel of the at least the pair of traction drive wheels to the frame, with at least one intervening pivot link between at least one traction drive wheel and the frame configured to maintain a substantially steady state traction contact patch between the at least one traction drive wheel and a rolling surface over rolling surface transients throughout traverse of the at least one traction drive wheel over the rolling surface.

Abstract:

An autonomous rover including a frame having a first end and a second end longitudinally spaced from the first end and forming a payload bay, the payload bay being sized to support a pickface, a common active registration surface configured to engage the pickface, and a drive section connected to the common active registration surface, the drive section being configured to variably position the common active registration surface relative to at least one storage shelf of an automated storage and retrieval system to effect placement of the pickface on the storage shelf so that pickfaces are substantially continuously arranged along the at least one storage shelf with a predetermined storage spacing between the pickfaces.

International Classification:

B65G 1/04
B60B 33/00
G05D 1/00

Abstract:

An autonomous transport vehicle, for transporting items in a storage and retrieval system, includes a frame, a controller, at least two independently driven drive wheels mounted to the frame, and at least one caster wheel mounted to the frame and having a castering assistance motor that engages the at least one caster wheel so as to impart castering assistance torque to the at least one caster wheel assisting castering of the at least one caster wheel. The controller is communicably connected to the castering assistance motor and configured to effect via a combination of vehicle yaw, generated by differential torque from the at least two independently driven drive wheels, and castering assistance torque from the castering assistance motor, castering of the at least one caster wheel with the autonomous transport vehicle in motion with a predetermined kinematic state.

International Classification:

B65G 1/04

Abstract:

A warehousing system includes a multilevel container storage array each level of which has a transport area and a storage area, a container transport vehicle located on each level to transport containers to and from container storage locations on each storage shelf on each level of the multilevel storage array to a breakpack operation station, a putwall of more than one levels of breakpack goods container stations distributed along each level with a corresponding breakpack goods transfer deck at each level of the putwall, a breakpack goods transport vehicle that transports breakpack goods along the corresponding breakpack goods transfer deck, and between corresponding breakpack goods transfer decks at different levels of the putwall, to each breakpack goods container station, and a controller effecting operation of the container transport vehicle between the container storage locations, the breakpack operation station, and a breakpack goods container located at a breakpack goods container station.
