Abstract
A multi-use hand truck or dolly apparatus and more particularly, a hand truck useable in the commercial building construction industry. It is capable of being used in both a vertical mode as well as a horizontal mode. When used in its vertical mode, it is capable of carrying up to five doors or other large objects. When used in its horizontal mode, it serves as a sturdy planar work support surface and permits a workman to perform required tasks thereon. Additonally, the apparatus can be joined with another like apparatus and present a much larger horizontal planar work surface. The apparatus includes telescopic frame members which permit accommodation of various length loads. Further, a plurality of swivel casters are provided which allow full rotational movement of the apparatus when used in its horizontal mode.
Claims20
A convertible, multi-use hand truck apparatus for transporting a plurality of generally rectangularly shaped objects and subsequently providing a sturdy workholding apparatus for said objects permitting work to be performed thereon, said apparatus comprising:
- frame means having at least a pair of telescopic members and including a handle at one end thereof and a base plate operably connected to the opposite end thereof;
- said base plate extending the full width of said frame means and extending outwardly therefrom perpendicularly thereto;
- primary transport means secured to the opposite end of said frame means below and slightly forward of said base plate;
- work supporting means including a plurality of pockets fixedly secured to said frame means providing a plurality of work supporting surfaces;
- said pockets having an upper open portion coincident with the plane of said telescopic members;
- a plurality of secondary omni-directional transport means operably connected beneath selected ones of said plurality of work supporting means whereby after placing said multi-use apparatus in a vertical position, a plurality of rectangular-shaped objects may be loaded onto said multi-use apparatus, transported to a work site and by subsequently lowering said multi-use apparatus into a horizontal position said secondary omni-directional transport means is brought into engagement with the floor and supports the entire load thereon and said primary transport means are raised off the floor permitting work operations to be performed on said rectangularly shaped objects in preparation for mounting said rectangularly shaped objects.
A convertible multi-use hand truck apparatus for transporting construction materials comprising:
- frame means including upper frame members and a handle means at one end thereof;
- a plurality of work supporting members positioned at spaced intervals along said frame means with one each positioned at an upper, middle and lower position thereof and securely fastened thereto;
- said work supporting members including a plurality of longitudinally planar supporting members which are received in pockets formed in said work supporting members;
- said pockets having an upper open portion coincident with the plane of said upper frame members;
- a planar wooden sheet overlaying said plurality of longitudinal planar supporting members and securely attached thereto;
- a plurality of omni-directional transport means securely attached to a base of selected ones of said work supporting members whereby when said convertible multi-use hand truck apparatus is placed in a horizontal position, said truck can be used to transport various construction materials from storage to a point of use.
