Abstract
Abstract The present invention provides a constructional component useful in forming shelving, framework and combinations thereof. By use of such constructional components, lightweight framework of any desired dimensions can be readily assembled by unskilled labor from a minimum number of standard sizes.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
213 words
A constructional component in the form of a beam for use in shelving or framework or both which comprises an elongated strip having extending from the longitudinal edges thereof a pair of uniformly converging sides of equal dimensions spaced from each other and unconnected at their terminal edges, each of which terminates in a first web extending outwardly therefrom, parallel to and beyond the longitudinal edge of said elongated strip and which terminates in a second web extending toward the elongated strip, the first and second webs being at essentially right angles to each other to form retaining channels which are shallow when compared with the length of said sides, and wherein the length of at least one of the retaining channels is such that it extends beyond a line drawn at right angles to the longitudinal edge of the elongated strip by the thickness of the material of which the beam is made, so that the lower end of a dependent flange of a filler panel can be inserted downwardly and retained in said at least one retaining channel, with the upper end of the dependent flange in abutting relationship with the upper end of the adjacent converging side of the beam substantially at the adjacent longitudinal edge of the elongated strip.
Claim 2
Dependent Claim
213 words
A constructional component in the form of a beam for use in shelving or framework or both which comprises an elongated strip having extending from the longitudinal edges thereof a pair of uniformly converging sides of equal dimensions spaced from each other and unconnected at their terminal edges, each of which terminates in a first web extending outwardly therefrom, parallel to and beyond the longitudinal edge of said elongated strip and which terminates in a second web extending toward the elongated strip, the first and second webs being at essentially right angles to each other to form retaining channels which are shallow when compared with the length of said sides, and wherein the length of at least one of the retaining channels is such that it extends beyond a line drawn at right angles to the longitudinal edge of the elongated strip by the thickness of the material of which the beam is made, so that the lower end of a dependent flange of a filler panel can be inserted downwardly and retained in said at least one retaining channel, with the upper end of the dependent flange in abutting relationship with the upper end of the adjacent converging side of the beam substantially at the adjacent longitudinal edge of the elongated strip.
Claim 3
Dependent Claim
51 words
A constructional component as claimed in claim 1 in which the retaining channels on each component are of different dimensions so that the larger retaining channel is sufficient to accommodate the smaller retaining channel of another constructional component in which the smaller retaining channel has the length specified in claim 1.
Claim 4
Dependent Claim
17 words
A component as claimed in claim 1 which contains uniformly spaced boltholes along the elongated strip thereof.
Claim 5
Dependent Claim
22 words
A component as claimed in claim 3 in which the boltholes are contained in a longitudinally extending recess in the elongated strip.
Claim 6
Dependent Claim
41 words
Shelving comprising a plurality of spaced constructional components as claimed in claim 1 and a plurality of filler panels having dependent flanges at the ends thereof, the lower ends of which are retained in the retaining channels of said constructional components.
Claim 7
Dependent Claim
12 words
Shelving as claimed in claim 5 which is bolted to a framework.
Claim 8
Dependent Claim
40 words
A framework comprising uprights and side members in which, the side members and uprights are formed from constructional components as claimed in claim 3 and in which the side members are fixed to the uprights by means of corner brackets.
Claim 9
Dependent Claim
114 words
A framework as claimed in claim 7 which includes crossmembers formed from the constructional component of identical type to those forming the side members and uprights, the crossmembers extending between said side members at the same level as that of each side member and retained in position by means of removable brackets in the ends of the crossmembers, and brackets having a horizontal portion located beneath the elongated strip of said crossmember, a leg portion located in the retaining channel of the side member and a pair of flanges extending from the vertical edges of the leg portion and in the same direction as the horizontal portion located in retaining channels of the crossmember.
Claim 10
Dependent Claim
67 words
Shelving comprising a plurality of spaced constructional components as claimed in claim 2 and a plurality of filler panels having dependent flanges at the ends, the lower ends of which are retained in the retaining channels of the said constructional components, which includes two constructional components in side-by-side relationship, the smaller retaining channel on one component being accommodated in the larger retaining channel of the other component.
