Abstract
Abstract A load transporting manually operated vehicle comprising a single tubular frame member with an upward extendable longitudinal handle member as a continuation thereof; a pair of flat load support cross-members. One load support cross-member has rotatable wheels positioned on each end thereof and is selectively positionable longitudinally along the frame member. The other support member is removably secured to the frame member in a fixed location between the other cross-member and the handle; a positionable upright member for preventing longitudinal load movement is positioned between the positionable cross-member and the distal end of the frame member at a selected location. Both of the cross-members have a plurality of apertures therealong for the attachment of resilient load restraining strap members passing over the load between selected apertures.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
169 words
An improved load bearing hand truck comprising: a single longitudinal support member having an upwardly curved end; a first and second load support member, said members positioned substantially transverse to and carried by said single longitudinal support member, said first load support member to rotatably secured to said single longitudinal support for rotation thereabout and rotatably supporting a wheel on each outer end thereof, said second load support member being spaced from said first load support member toward said upwardly curved end; a handle member removably attached to the upwardly curved end of said single longitudinal support member and extending therefrom in a first direction, angled upwardly in a second direction and downwardly in a third direction forming a handle on the distal end thereof; and a single load steadying member carried by and sectionally positionable along said single longitudinal support member for adjustment to load size, said load steadying member is positionable between said first load support member and the distal end of said single longitudinal support member.
Claim 2
Dependent Claim
169 words
An improved load bearing hand truck comprising: a single longitudinal support member having an upwardly curved end; a first and second load support member, said members positioned substantially transverse to and carried by said single longitudinal support member, said first load support member to rotatably secured to said single longitudinal support for rotation thereabout and rotatably supporting a wheel on each outer end thereof, said second load support member being spaced from said first load support member toward said upwardly curved end; a handle member removably attached to the upwardly curved end of said single longitudinal support member and extending therefrom in a first direction, angled upwardly in a second direction and downwardly in a third direction forming a handle on the distal end thereof; and a single load steadying member carried by and sectionally positionable along said single longitudinal support member for adjustment to load size, said load steadying member is positionable between said first load support member and the distal end of said single longitudinal support member.
Claim 3
Dependent Claim
31 words
The invention as defined in claim 1 wherein said single longitudinal member is tubular, said handle member is tubular and said single longitudinal member and handle member have a telescoping connection.
Claim 4
Dependent Claim
86 words
The invention as defined in claim 2 wherein said upwardly curved end of said single longitudinal support member has at least two transverse bores therealong and said handle member has a single aligning bore therethrough wherein when said aligning bore of said handle member is moved from alignment with one of said at least two bores through said upwardly curved portion of single longitudinal support member to alignment with a second bore of said at least two bores, the elevation of said handle member is changed.
Claim 5
Dependent Claim
47 words
The invention as defined in claim 3 wherein a removable keeper means is inserted through said handle member aligning bore and a selected one of said bores of said upwardly curved end of said longitudinal support member for securing said handle member to said longitudinal support member.
Claim 6
Dependent Claim
55 words
The invention as defined in claim 1 wherein said single longitudinal support member has a plurality of pairs of bores therethrough whereby said first load support member can be positioned between a selected pair of said plurality of pairs of bores and locked in position by keeper means inserted through the selected pair of bores.
Claim 7
Dependent Claim
39 words
The invention as defined in claim 1 wherein said first and second load support members have a plurality of bores therealong and resilient strap members retained by a pair of said bores biases the load to said hand truck.
