Definitions

  • THE PRESENT INVENTION relates to a platform.
  • One embodiment of the invention particularly relates to a working platform or stage primarily intended for use by builders and/or decorators. Whilst the invention will be described with reference to this primary appli­cation it should be appreciated that the platform may have other applications. For example, the platform may be used as a stage by actors.
  • Another embodiment of the invention may comprise a permanent fixture to be in­corporated in a building.
  • a platform or stage it is sometimes necessary to erect a platform or stage for use by builders or decorators, the platform or stage being erected inside a building.
  • a platform or stage may be constructed on a sup­porting framework formed from conventional scaffolding tubes and couplers, or formed from scaffold frames. Whilst such a framework may be satisfactory in use, the scaffolding tubes or the scaffold frames may damage the floor upon which the stage or platform is erected. This is clearly inconvenient, especially if the floor is a screeded floor which is subsequently to be tiled, or if the floor is a woodblock floor.
  • the present invention seeks to provide a plat­form or stage which can be erected without damaging the under-lying floor.
  • the invention also seeks to provide a staging or platform that can be assembled quickly, at a low cost.
  • a platform comprising a plurality of support elements engaging an under-lying floor, a plur­ality of support members extending between the support elements, the support members supporting directly or in­directly a plurality of panels constituting the upper surface of the said platform, the support elements hav­ing at least the part thereof engaging the under-lying floor made from a yieldable material.
  • the yieldable material comprises an expanded or foamed plastics material.
  • the yieldable material comprises expanded polystyrene.
  • each support element is made as an integral element formed of said yieldable material.
  • each support element comprises one or more components located one on top of the other, at least the lowest component being formed entirely of said yieldable material.
  • the support elements define a substantially regular square array
  • the support members comprise first members extending between sup­port elements defining rows of said elements, and trans­verse support members resting thereon, the sheets form­ing the surface of said platform resting on the said transverse support members.
  • the joints between adjacent sheets which extend parallel to said transverse support members are located immediately above selected ones of said transverse support members.
  • transverse support members comprise planks or scaffolding boards.
  • each transverse support comprises two superimposed planks or scaffolding boards.
  • the said first support members com­prise planks or scaffold boards retained in a vertical or "on edge” condition.
  • each support element is provided with at least one groove formed in the upper surface thereof, the groove receiving an edge portion of a said plank or scaffold board.
  • each support element is provided with two parallel grooves formed in the upper surface thereof, each receiving an edge portion of a respective plank or scaffold board.
  • the invention also relates to a platform structure comprising a plurality of platforms as des­cribed superimposed one on the other.
  • a platform or stage 1 in accordance with the invention comprises a plurality of supporting elements 2 which rest upon an under-lying floor 3.
  • the elements 2 form a regular square array.
  • the supporting elements in the presently des­cribed embodiment of the invention each comprise a single block of a rigid but yieldable expanded or foamed plastics material.
  • a suitable material is expanded polystyrene, but other materials having similar proper­ties may be utilised.
  • Each element 2 is of regular parallelipidic form.
  • Two parallel transverse grooves or slots 4 are formed in the upper face of each block.
  • the blocks in each row of blocks are aligned so that the grooves 4 in the upper faces thereof are co-aligned.
  • Wooden planks or scaffold boards 5 are inserted edge-wise into the slots 4 to act as support members.
  • Each plank 5 is sub­stantially vertical.
  • Each plank 5 may extend between two adjacent blocks in the row or may even extend across three or four blocks in the row.
  • planks or scaffold boards 6 may be located extending transversely across the tops of the rows of vertical planks 5.
  • the planks 6 may be located in super-imposed pairs.
  • the horizontal planks 6 extend­ing between the adjacent rows of vertical planks 5 may be staggered.
  • panels or sheets 8 of plywood, chip­board or other similar material may be located on top of the horizontal planks 6. It may be necessary for these panels to be staggered slightly, as shown at 9, in view of the stagger of the under-lying supporting planks 6. It is to be appreciated that each join between the panels 8 parallel to the axis of the planks 6 should actually lie immediately over the centre of a plank 6.
  • the positioning of the elements 2 may be adjusted within wide limits, but preferably the positioning is such that the elements 2 are able to withstand the load that is to be supported by the platform 1. If the platform is to carry a heavy load the elements 2 should be relatively close together. However, if the platform is only to carry a relatively light load, then the elements 2 may be further apart.
  • the supporting members extending between the elements 2 may comprise timber, steel or aluminium beams. It is not essential for these support members to be recessed into grooves in the elements in any way, and thus in certain embodiments, the transverse slots 4 may be omit­ted.
  • Figure 2 illustrates an embodiment of the in­vention which is similar to that illustrated in Fig­ure 1, and like reference numerals apply to like parts.
  • each element 2 rests on top of another under-lying block 10, with the block 10 resting upon the floor 3.
  • the block 10 is made of expanded polystyrene.
  • the the platform of Figure 2 is located higher above the floor than is the platform of Figure 1. It is to be appreciated that the dimension of the ele­ments 2 and the blocks 10 in the vertical direction may be selected to provide a platform having any desired height above the under-lying floor 3.
  • the platform or stage may be readily erected in a room of any size. Since the support elements 2 (and the blocks 10) are formed of expanded polystyrene, the load bearing parts of the platform or stage, as repre­sented by the lower parts of the elements 2 and the blocks 10 which actually touch the floor, are of a yieldable material. Thus the stage or platform will not damage an under-lying floor, even if the floor is deli­cate, such as a woodblock floor.
  • Figure 3 is a perspective view illustrating a modified embodiment of the invention in which a first platform assembly 11, as described with refernce to Fig­ure 2, rests upon the floor 3, and a second platform assembly 12 rests upon the platform assembly 11.
  • the lower-most blocks 10 of the platform assembly 12 may have pairs of transverse grooves 13 formed thereon, to engage the upper edges of the planks 5, thus relatively rigidly inter-connecting the upper platform assembly 12, and the lower platform assembly 11.
  • the lower-most blocks 10 of the upper platform assembly 12 may have planar under-surfaces 14, without transverse grooves, and the planar under-surfaces 14 will then just rest on the panels or sheets 8 of the lower platform assembly 11.
  • Such a platform may comprise a permanent fitting within a building.
