Abstract

1479136 Hand trucks KAI CASSIMALLY 20 June 1974 [6 April 1973] 16597/73 Addition to 1301488 Heading B7B In a combined collapsible trolley and portable case, in which wheel assemblies 40, 42 are arranged to be stored within a recess in a face of the case and pivoted away from the case into an operable trolley position, an extendable framework 12, operatively connected with the wheel assemblies, is pivotally attached to the case and rotated from a recess in a face of the case to contain luggage between the framework and the case. In one embodiment, Figs. 1, 3 the trolley 10 comprises a portable case 11 and trolley framework 12 in which a U-shape handle 22 with side arms 23, 24 is slidable within hollow bars 26, 27 which are pivotally attached to the cross bar 36 of lid 16. Wheel assemblies 40, 42 carry integral sleeves 50, Fig. 3, which are slidable and rotatable along bar 26, 27. A pin 56 mounted on the side bar 26, 27 is locatable within one or other of the sleeve slots 52, 54 depending on whether the wheel assemblies are in the stored or extended position. With the handle 22 retracted into bars 26, 27 and the wheel assemblies stored inwards, the trolley framework may be stored within recesses 60 formed in the lid 16. In another embodiment, Fig. 5, the side bars 26, 27 of the framework are pivotally mounted via joints 90, 91 on crossbar 84 having rib bars 86, 87 which are received in bores 110, 111 in the bottom panel 15 thus allowing the framework to be detached from the portable case. A back plate 100 attached to cross-bar 84 forms a rigid stop for bars 26, 27 when the framework is extended. A fabric cover 120 permanently attached to the back side wall may be fastened by a zipper 122 to the ease. A separate bottom panel 130 can be detachably connected to the case by bolts 132 insertable into threaded bores in the case.
