Abstract
Abstract A pallet comprising top and bottom floors, a pair of side frames and a pair of end frames connectable together to form a box frame which when it is assembled is adapted to hold the top and bottom floors in position. Each of the frames has a pair of parallel longitudinal grooves, whereby when the box frame is assembled a pair of peripheral grooves are formed which serve for retaining the floors in position.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
141 words
A box structure comprising a pair of side frames and a pair of end frames connectable together to form a boxframe structure; upper and lower longitudinal grooves in each of the frames arranged such that a vertically spaced parallel pair of peripheral grooves are formed in the boxframe structure on assembly of the structure, a transverse member at each end of each side frame including a groove transverse to the frame to receive an end of an adjacent end frame; upper and lower floors adapted to be clamped between the side frames; and fastening means releasably connecting adjacent enDs of adjoining side and end frames to permit assembly of said boxframe structure with the peripheral edges of said upper and lower floors located in position in the peripheral grooves, the fastening means effecting clamping of the floors between the side frames.
Claim 2
Dependent Claim
141 words
A box structure comprising a pair of side frames and a pair of end frames connectable together to form a boxframe structure; upper and lower longitudinal grooves in each of the frames arranged such that a vertically spaced parallel pair of peripheral grooves are formed in the boxframe structure on assembly of the structure, a transverse member at each end of each side frame including a groove transverse to the frame to receive an end of an adjacent end frame; upper and lower floors adapted to be clamped between the side frames; and fastening means releasably connecting adjacent enDs of adjoining side and end frames to permit assembly of said boxframe structure with the peripheral edges of said upper and lower floors located in position in the peripheral grooves, the fastening means effecting clamping of the floors between the side frames.
Claim 3
Dependent Claim
42 words
A box structure as claimed in claim 1, wherein the box structure is in the form of a pallet and at least one aperture is provided in any of the side frames and the end frames to facilitate lifting of the pallet.
Claim 4
Dependent Claim
35 words
A box structure as claimed in claim 1, wherein a transverse member is provided at each end of each end frame, and the fastening means connect adjacent transverse members of adjoining side and end frames.
Claim 5
Dependent Claim
33 words
A box structure as claimed in claim 1, wherein additional opposed transverse grooves are provided in any of the side and end frames to receive the ends of further crossbeams linking opposed frames.
Claim 6
Dependent Claim
61 words
A box structure as claimed in claim 1, wherein each side frame is comprised by a pair of spaced parallel longitudinal channel members providing the longitudinal grooves and the transverse members are comprised by channel members linking the longitudinal channel members at each end, each transverse channel member providing the transverse groove for receiving an end of the adjoining end frame.
Claim 7
Dependent Claim
17 words
A box structure as claimed in claim 1, wherein the frames are made from mild steel metal.
Claim 8
Dependent Claim
35 words
A box structure as claimed in claim 1, wherein the floors are built up from planks, the planks of each floor being slid transversely into respective opposed longitudinal grooves during assembly of the box structure.
Claim 9
Dependent Claim
17 words
