The present invention relates to an overhead trolley switching system which is operative in both manual and automatic modes. The switching system is particularly suited for the storage of overhead trolleys and includes a secondary rail spaced from the main rail along with a switching rail adapted to divert one wheel assembly from the main rail. The trolleys can, if desired, be stored in a diagonal position.

A trolley rail is formed from a plurality of aligned tubular housings, each of which has a front side provided with laterally spaced slots extending lengthwise of the rail, and a partition wall extending across the inside of the housing and closing the inner sides of the slots, the side walls of which are provided with grooves receiving electrical conductor bars. The partition wall and the back of the housing have pairs of aligned openings therethrough, with each pair of openings connecting with...

A method of aligning and subsequently fixing a horizontal track relative to a plurality of trolleys where the trolleys are movable along a straight line, and an improved bottom trolley and fixed structure.

A trolley comprising a substantially rectangular support framework and wheels mounted on one end of support arms, the other ends of the arms being pivoted to the framework and the arms being movable to several positions so that the trolley can be used for different purposes.

A trolley car for conveying articles along a monorail having arcuate portions includes a rigid frame having a longitudinal axis and opposed ends. A pair of rotatable yokes are coupled to the frame adjacent to the opposed ends of the frame for rotational movement around an axis perpendicular to the longitudinal axis as the trolley car travels along an arcuate portion of the monorail, each of the yokes having a pair of opposed arms extending from the mainframe, a pair of guide wheels mounted on ea...

A collapsible trolley adapted for transporting and launching dinghies and like-sized boats comprises a rear axle having endwise disposed wheels and a Y-frame comprising a forward spine and trailing frame members pivotted thereto and deployable between a stowing position alongside the spine and an operational position in which the ends of the frame members remote from their spine pivot ends are releasably attachable to the axle near the ends thereof.

A transfer trolley, to lift loads but particularly adapted to pick up a patient from a bet using a plurality of horizontally extending tines. Each tine consists of a tube having one end fixed in a position and a free open end. A sleeve surrounds the tube and is withdrawn into the interior of the tubes. The tines are then located next to a patient and a fluid under pressure is inserted into the sleeve, causing the sleeve to emerge from the end of the tube and to insinuate itself under the patient...

An improved trolley for use on a track. The improved trolley is of a sandwich construction having a wear resistant interior and a pair of metal end plates. The wear resistant material is preferably plastic or other material designed to avoid damaging a track along which the trolley rides. The end plates are preferably stainless steel and of a diameter greater than the diameter of the center wheel to prevent the trolley from becoming dislodged from a track. By providing a sandwich of long wearing...

A plastic trolley, such as a shopping trolley or luggage trolley, includes a loading element, such as a basket or a loading platform which loading element is provided with a handle and is supported by wheels. The loading element and the handle are manufactured in one piece with double walls by means of rotational molding. Furthermore, the basket can have holes which are formed by interconnected parts of the adjacent walls of the double wall construction of the basket.

A lightweight, collapsible golf trolley is disclosed comprising an extruded elongate chassis member 1 of lightweight metal or alloy, e.g. aluminum. The chassis member 1 is of an inverted channel section with two downwardly and outwardly flared side wall sections 2, 3 against which are pivoted the wheel struts 4, 5 which are likewise lightweight alloy extrusions. Preferably the struts are in two halves forming a parallel linkage with the chassis and the wheel brackets 13. Hinged to the forward en...
