Abstract
Abstract A support element for an end of a board, intended for use in pairs to form a raised working platform or bench, comprises a first upwardly-facing support surface adapted to engage the underside of the board at its end, a second downwardly facing support surface parallel to and spaced vertically from the plane of the first supporting surface by a distance equal to the thickness of the board and spaced horizontally from the first supporting surface to engage the upper surface of the board a predetermined distance from its end, and at least one ground engaging surface so positioned that, in use, the support element engages the ground at a point directly below the first supporting surface, or a point spaced therefrom horizontally in the direction away from the second supporting surface.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
210 words
A support element for an elongate board or the like, comprising a first upwardly-facing support surface adapted to engage the underside of the board at its end, a second downwardly facing support surface parallel to and spaced vertically from the plane of the first supporting surface by a distance equal to the thickness of the board and spaced horizontally from the first supporting surface to engage the upper surface of the board a predetermined distance from its end, and at least one ground engaging surface so positioned that in use the support element engages the ground at a point directly below the first supporting surface or at a point spaced therefrom horizontally in the direction away from the second supporting surface, wherein a pair of legs are joined at one of their respective ends by a transversely extending plate, each of the legs having one of a pair of parallel bars fixed to it on its side adjacent the other leg, and the bars extending in a plane parallel to the plate and inclined to the axial direction of the legs, so that the side of the plate facing the bars constitutes the second supporting surface, and the sides of the bars nearest the plate consitute the first supporting surface.
Claim 2
Dependent Claim
210 words
A support element for an elongate board or the like, comprising a first upwardly-facing support surface adapted to engage the underside of the board at its end, a second downwardly facing support surface parallel to and spaced vertically from the plane of the first supporting surface by a distance equal to the thickness of the board and spaced horizontally from the first supporting surface to engage the upper surface of the board a predetermined distance from its end, and at least one ground engaging surface so positioned that in use the support element engages the ground at a point directly below the first supporting surface or at a point spaced therefrom horizontally in the direction away from the second supporting surface, wherein a pair of legs are joined at one of their respective ends by a transversely extending plate, each of the legs having one of a pair of parallel bars fixed to it on its side adjacent the other leg, and the bars extending in a plane parallel to the plate and inclined to the axial direction of the legs, so that the side of the plate facing the bars constitutes the second supporting surface, and the sides of the bars nearest the plate consitute the first supporting surface.
Claim 3
Dependent Claim
45 words
A support element according to claim 1, wherein the bars are joined at one of their respective ends by a transverse member having a stop surface situated in a plane perpendicular to the bars and between the planes of the first and second supporting surfaces.
Claim 4
Dependent Claim
22 words
A supporting element according to claim 2, wherein the ends of the legs extend to intersect the plane of the stop surface.
Claim 5
Dependent Claim
34 words
A support element according to claim 1, wherein the parallel bars have steps formed in their sides adjacent the plate, to provide first supporting surfaces at two different spacings from the second supporting surface.
Claim 6
Dependent Claim
14 words
A support element according to claim 1, wherein the legs are adjustable in length.
Claim 7
Dependent Claim
12 words
A support element according to claim 1, wherein the legs are parallel.
Claim 8
Dependent Claim
26 words
A support element according to claim 1, wherein the legs diverge over at least a part of their length in the direction away from the plate.
Claim 9
Dependent Claim
24 words
A support element according to claim 1, in which laterally extending feet are formed at the ends of the legs remote from the plate.
Claim 10
Dependent Claim
139 words
A support element for an elongate board or the like comprising a pair of legs joined at one of their respective ends by a transverse member, and each leg having fixed to it on its side adjacent the other leg one of a pair of parallel bars extending generally transversely to the axial direction of the legs, the sides of the bars facing the transverse member constituting, in use, a first supporting surface engaging the underside of the board at its end, and the slide of the transverse member facing the bars constituting, in use a second supporting surface engaging the upper surface of the board at a distance from its end, and the end surfaces of the legs remote from the transverse member constituting, in use, ground-engaging surfaces positioned vertically below or beyond the end of the board.
Claim 11
Dependent Claim
139 words
A support element for an elongate board or the like comprising a pair of legs joined at one of their respective ends by a transverse member, and each leg having fixed to it on its side adjacent the other leg one of a pair of parallel bars extending generally transversely to the axial direction of the legs, the sides of the bars facing the transverse member constituting, in use, a first supporting surface engaging the underside of the board at its end, and the slide of the transverse member facing the bars constituting, in use a second supporting surface engaging the upper surface of the board at a distance from its end, and the end surfaces of the legs remote from the transverse member constituting, in use, ground-engaging surfaces positioned vertically below or beyond the end of the board.
Claim 12
Dependent Claim
34 words
A support element as claimed in claim 9, wherein the bars are inclined to the transverse direction of the legs, the legs being fixed to the bars at about the midpoints of the bars.
Claim 13
Dependent Claim
46 words
A support element according to claim 10 wherein the bars are joined at one of their respective ends by a second transverse member having a stop surface situated in a plane perpendicular to the bars and between the planes of the first and second supporting surfaces.
Claim 14
Dependent Claim
22 words
A supporting element according to claim 11 wherein the ends of the legs extend to intersect the plane of the stop surface.
Claim 15
Dependent Claim
35 words
A support element according to claim 9 wherein the parallel bars have steps formed in their sides adjacent the transverse member, to provide first supporting surfaces at two different spacings from the second supporting surface.
Claim 16
Dependent Claim
14 words
A support element according to claim 9 wherein the legs are adjustable in length.
Claim 17
Dependent Claim
12 words
A support element according to claim 9 wherein the legs are parallel.
Claim 18
Dependent Claim
27 words
A support element according to claim 9 wherein the legs diverge over at least a part of their length in the direction away from the transverse member.
Claim 19
Dependent Claim
25 words
A support element according to claim 9 in which laterally extending feet are formed at the ends of the legs remote from the transverse member.
