DETAILED DESCRIPTION OF THE INVENTION
According to the invention there is provided a support member 100, suitable' for engagement with a scaffold frame 200 having horizontal and/or vertical frame members 210a & 210b. The support member 100 comprises a moulded support platform 110; and a pair of gripping members 150, in the form of rubber inserts
154, which are received into recessed channels 120 in the lower part of the support platform 110. The rubber inserts 154 are secured to the support platform 110 by bonding, or by being integrally moulded as part of the support platform, for operationally increasing the friction between the support platform 110 and a frame member 210a & 210b. Typically the support platform 110 will be elongate in the form of a plank or decking member having a tread pattern 130 on its upper surface, and will be moulded in a moulding process, such as a polymeric or thermoplastic moulding process.
In the embodiment show in the figures, the gripping member 150 is triangularly shaped in cross section, and is received into and secured to complementary shaped recessed channels 120 in the underside of the support platform 110. It is envisaged that the gripping member 150 will be integrally formed in the recessed channels 120 in the moulding process described above.
However, in an alternative embodiment, the gripping member 150 may be secured to the support platform 110 by means of a gripping formation such as a snap-fit-type formation (not shown). The gripping member 150 is composed of material having relatively high frictional qualities when used on metal frame members, such as rubber, synthetic polymers, or the like.
The gripping member 150 further includes a tread pattern 160 on its lower surface 152 to increase its effective frictional coefficient against the frame members 210a & 210b.
In a preferred embodiment shown in figures 5-9, the support member 100 further comprises a -reinforcing element 180 for reinforcing the bending characteristics of the support member 100. The reinforcing element 180 is envisaged as being integrally moulded with the support platform 110, however, it may also be engaged with the support platform 110 by alternative means, such as by means of snap-fit engaging formations (not shown), or by more permanent securing means such as screws, bolts of the like (not shown).
The reinforcing element shown in figures 5-7 is tubular, having a square cross section, however, it is envisaged that the reinforcing element 180 can be of a wide variety of shapes, including circular, rectangular, triangular, or any other shape. Q
Typically, the reinforcing element 180 will be composed of metal, such as steel, although it could be composed of any other material having the required bending characteristics, including hard plastic, wood or the like.
In addition, the support member 100 includes securing means 170 in the form of a combination of securing straps 172 and securing lugs 174 located towards the end of the support platform 110. The securing straps 172 are configured and dimensioned to be wrapped around a frame member 210a or 210b to engage with a securing lug 174 of a longitudinally adjacent support member 100, thereby securing the support member 100 to the frame member 210a & 210b. It is further envisaged that the securing straps 172 -will be composed of an elastic substance such as rubber, polymeric substances or the like, so that it is resilientiy flexible, to hold the support platform 110 against the frame member 210a & 210b. It is envisaged that each support member 100 will typically be secured to a scaffold frame at both ends of the support member 100. Typically, the securing lugs 174 will be integrally formed with the support platform 110, although the securing lugs may be attached to the support platform 110 by any other means, such as securing formations (not shown), thread ■ formations (not shown) or the like.
The securing means 170 further comprises securing recesses 176 which have been moulded into the support platform 110. The securing recesses 76 are configured and dimensioned for receiving the securing lug 174 of an adjacent similar support member 100 laying alongside each other, thereby securing and stabilising the adjacent support members 100, and creating a wider stable platform for workers (not shown) to operate on. In a second aspect of the invention, there is provided a scaffold engaging arrangement 300, as shown in figures 1, 3, 5 and 6, suitable for engagement with a scaffold frame comprising horizontal and/or vertical frame members 210a & 210b.' The scaffold engaging arrangement 300 comprises a plurality of support member 100 as described above; and a plurality of sleeve members 310 configured and dimension to receive a scaffold frame member 210a & 210b. As shown in figure 1, and 5 the securing straps 172 and supporting lugs 174 of adjacent support members 100 are adapted and configured to engage with each other. In this way, the adjacent support members 100 can be secured to the frame members 210a & 210b and each other.
It is envisaged that a scaffold structure that includes a scaffold frame 200; on which is laid a plurality of support members 100 as described above will provide safer working conditions on a construction site, without significantly increasing the amount of effort required to erect the scaffold structure.
Where in the foregoing description reference has been made to elements or integers having known equivalents, then such equivalents are included as if they were individually set forth.
Although the invention has been described by way of example and with reference to particular embodiments, it is to be understood that modifications and/or improvements may be made without departing from the scope or spirit of the invention.
