摘要： The present invention is for standing boards that may be connected to buggies or prams which do not have a rear wheel shaft or otherwise are so designed that connecting of the standing board to the rear shaft is not always suitable. The standing board has a board, wheels at the rear end of the board, and mounting arms which connect the standing board to the buggy. The mounting arms are so designed that there is free space for the wheels of the buggy, possible breaking means etc., thus the mounting arms are curved so that they extend forwards and upwards from the board. The mounting of the arms at the standing board is such that the arms may take one out of several distinct positions relative to the board and when in use are fixedly arranged relative to the board. For this purpose the arms are fixed into bushings which in turn are fixed into mounting parts which preferably are integrated parts of the board of the standing board.

摘要： The present invention involves a method of controlling a vehicle steer-by-wire system having two independent road wheels. In one embodiment, the method comprises providing a steering wheel control sub-system to generate road wheel reference angles and to produce steering feel for a vehicle driver. The method further includes providing a road wheel control sub-system including a multivariable road wheel controlled plant and a multivariable road wheel controller for controlling actual road wheel angles to track to road wheel reference angles within a servo control system structure having road wheel angular position feedback and road wheel angular rate feedback loops. The method includes modeling the multivariable road wheel controlled plant and implementing the multivariable road wheel controller. Moreover, the method includes applying road wheel angles and angular rates as feedback signals to construct a servo control system with the multivariable controlled plant and the multivariable road wheel controller to implement the left and right road wheel angles tracking for left and right road wheel reference angles. Then, the method includes receiving left and right road wheel reference angles being based on the steering wheel angle command from the steering wheel control sub-system and receiving the left and right road wheel angles from the multivariable road wheel controlled plant. The method includes calculating the left and right road wheel angle errors based on the left and right road wheel angles and left and right road wheel reference angles and generating the left and right road wheel torque control variables from the multivariable road wheel controller with servo control performances based on the left and right road wheel angle errors. After generating road wheel torque control variables, the method includes applying torque control variables of the multivariable road wheel controller to the multivariable controlled plant to control tracking of the actual left and right wheel angles with the left and right road wheel reference angles, respectively.

摘要： A dual position hand truck includes a central frame having two side rails and a toe plate. Positioned at an upper end of the central frame is a U-shaped handle bar which has a hand gripping portion and two extended legs with castered wheels attached at their respective bottom ends. The handle bar is pivotally attached to the frame by a fixed shaft and a pair of support brackets. The support brackets also allow the extended legs to slide along their length. Attached to the support brackets is a spring biased locking bar which locks the handle bar against rotational movement relative to the frame.

摘要： A platter cart for carrying a plurality of loaded trays has an upwardly extending, wheeled support frame and a plurality of spaced horizontal shelves secured between the opposite sides of the frame. Each shelf comprises a bar extending between the sides of the frame and formed into a serpentine configuration including at least a central portion of generally W-shape, the serpentine configuration having a central axis of symmetry aligned with the central axis of the frame. The sides of the cart are generally tapered inwardly from the rear to the front end of the frame, and the frame is open at its rear end so that carts can be nested together with the W-shaped shelves and tapered sides interfitting for nesting purposes.

摘要： A convertible hand cart convertible between a two wheel hand cart for vertically loading of materials and a four wheel hand cart providing a horizontal material loading platform. The wheel structure for providing the four wheel configuration is pivotably secured to the two wheel structure and movable between the two wheel and four wheel configurations. The two wheel configuration includes structures for locking up the wheel structure for the four wheel configuration thereto. The locking structure is constructed and defined with minimum parts and operable based on vertical sliding action to minimize wear on the locking structure parts. A foot operative mechanism is provided to release the locking structure to permit the wheel structure to be released from a locked up position, hands free, to commence the reconfiguration to the four wheel cart.

摘要： A sanitary handle cover for a shopping cart comprises a first semi-flexible sheet of a vinyl construction and a second sheet of fabric superimposed thereon and heat bonded thereto. Corresponding lateral edges of first and second sheets define a width dimension that is sufficient such that the sheets may be wrapped about a shopping cart handle bar. The width dimension is also sufficient such that a portion of the first sheet overlaps a portion of the second sheet. Circular hook and loop fasteners are arranged in a spaced apart configuration along the longitudinal edges that overlap so as to securely maintain the cover on the handle bar. Spring clip fasteners depend from opposed corresponding lateral edges of first and second sheets such that the cover may be coupled to a bag or purse and be used as a carrying strap therefor. A pocket is fixedly attached to the inner surface of the first sheet and has an opening adjacent corresponding lateral edges for holding a pen while shopping.

摘要： A method for facilitating movement of a plurality of nested trollies (including a leading trolley and a trailing trolley), the method comprising the steps of connecting an adjustable ratchet-type tension mechanism between the leading and trailing trolleys, and actuating the tension mechanism so as to produce a preselected tension between the leading and trailing trolleys to thereby hold the nested trolleys tightly together. In the preferred embodiment, the preselected tension is sufficient to upwardly the leading and trailing trolleys off of the ground surface.

摘要： A platter cart has a wheeled base and at least one vertical support extending upwardly from each side of the base at a location spaced between the front and rear end of the base. A series of front shelves are secured to extend forwardly from the supports at spaced intervals, and a series of horizontal rear shelves are secured to extend rearwardly from the supports at spaced intervals. Each rear shelf is vertically offset from the front shelves, so that two platter carts can be nested together by pushing a rearward cart into the end of a front cart with the front shelves of the rearward cart nesting into the spaces between the rear shelves of the front cart.
