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
A box structure as claimed in claim 1, wherein the floors are comprised by a unitary panel.
Claim 10
Dependent Claim 33 words
A box structure as claimed in claim 1, wherein each end frame is formed from a channel-sectioned plate having a central longitudinal recess to provide the end frame with the parallel longitudinal grooves.
Claim 11
Dependent Claim 40 words
A box structure as claimed in claim 1, wherein each end frame is formed from a channel-sectioned plate having a longitudinally extending beam attached to the floor thereof whereby the two parallel longitudinal grooves are formed in the end frame.
Claim 12
Dependent Claim 33 words
A box structure as claimed in claim 3, wherein the fastening means are comprised by bolts extending longitudinally to the end frames and connecting adjacent transverse members of adjoining side and end frames.
Claim 13
Dependent Claim 49 words
A box structure as claimed in claim 5, wherein each transverse channel member consists of a main body part providing a transverse groove, and a pair of parallel legs extending from the body part for attachment to the respective ends of the longitudinal channel members of the side frame.
Claim 14
Dependent Claim 32 words
A box structure as claimed in claim 5, wherein one or more intermediately spaced transverse channels are provided in each side frame, each transverse channel receiving an end of a respective crossbeam.
Claim 15
Dependent Claim 20 words
A box structure as claimed in claim 7, wherein the planks are in the form of floorboards having tongue-in-groove connections.
Claim 16
Dependent Claim 33 words
A box structure as claimed in claim 7, wherein at least one pair of spacers are located in opposed longitudinal grooves, between respective adjacent planks, whereby said adjacent planks define a space therebetween.
Claim 17
Dependent Claim 42 words
A box structure as claimed in claim 9, wherein a web is provided at each end of the recess and extends between the sidewalls thereof, each web including means to enable the adjoining side frame to be bolted to the end frame.
