Abstract

The retaining apparatus in the form of a coupler 10 comprises a first clamp 12 in order to secure the coupler 10 to a first scaffolding pole 100. The first scaffolding pole 100 is a support scaffolding pole which extends vertically up from the ground. The coupler 10 comprises second and third clamps 30, 32 which are arranged to secure second and third scaffolding poles at an identical height on to the first scaffolding pole. The second and third scaffolding poles extend horizontally from the first scaffolding pole and are arranged to support a safety platform for use within construction units whilst building is progressing. The coupler enables pre-existing standard scaffolding poles to be used rather than adapted scaffolding poles having clamps permanently mounted thereon.

Description

<Desc/Clms Page number 1>
Retaining Apparatus Field of the Invention The present invention relates to retaining apparatus for retaining scaffolding poles, an assembly comprising retaining apparatus and at least one scaffolding pole and a method of retaining scaffolding poles.
Background to the Invention Scaffolding poles are generally secured to each other using clips or couplers. A conventional clip comprises a first clamp for securing around a first scaffolding pole and a second clamp for securing around a second scaffolding pole. Accordingly, a horizontal pole can be secured to a vertical pole by securing the clip on the vertical pole and then securing the horizontal pole in the clip. If two horizontal poles need to be secured to the vertical pole then this requires the use of two clips.
However, it is not possible to secure the two clips at the same height on the vertical pole and, therefore, the two horizontal poles will be at different vertical heights. Whilst this may be sufficient for horizontal poles for stabilising a structure there are situations where the horizontal poles must be secured at the same vertical height.
Prior art clips can retain two horizontal poles at the same height to a vertical pole. However, such clips require further specific interlocking apparatus which is secured to the end of the horizontal poles. The interlocking apparatus at the ends of the pole engages
<Desc/Clms Page number 2>
with a specific engagement means provided on the vertical scaffolding pole. Since such apparatus is provided on the end of the scaffolding pole it is not possible to easily adjust the length of the horizontal pole. Accordingly, the vertical poles must be spaced by the identical length of the horizontal poles. Therefore, most prior art clips are not flexible for use in many situations.
It is an aim of the present invention to overcome at least one problem associated with the prior art whether referred to herein or otherwise.

Description of the Preferred Embodiment As shown in Figures 1 to 4, the retaining apparatus in the form of a coupler 10 comprises first retaining means in the form of a first clamp 12 in order to secure the coupler 10 to a first scaffolding pole. The first scaffolding pole may be a support scaffolding pole and is arranged to extend vertically up from the ground. The coupler 10 comprises second retaining means in the form of a second clamp 30 and third retaining means in the form of a third clamp 32. The second and third clamps 30,32 enable a second scaffolding pole and a third scaffolding pole to be secured to the first scaffolding pole by the coupler 10 and retained thereto. The coupler 10 is releasably securable to the first scaffolding pole. The coupler 10 can, therefore, be secured to the first scaffolding pole at a chosen position in order to secure two scaffolding poles thereto at an identical height. In addition, the coupler may be arranged to secure more than two scaffolding poles at an identical height through the
<Desc/Clms Page number 10>
addition of further retaining means or clamps to the coupler.
If the scaffolding assembly includes a level surface, the couplers 10 are secured to substantially vertical supporting scaffolding poles. Further scaffolding poles can then be secured to the couplers 10 on the vertical scaffolding poles and extend horizontally therefrom. The horizontal scaffolding poles can then support a surface which may comprise scaffolding planks supported across the horizontal poles. The final surface may comprise sheets of wood supported on the scaffolding planks.
The scaffolding assembly may comprise a safety platform for use within construction units whilst building is progressing. For example, the scaffolding assembly may comprise a safety platform that provides a surface spaced from the ground such that if a builder or other work falls then the potential falling distance is decreased. Prior art safety platforms have used vertical support scaffolding poles on which clamps are permanently mounted for retaining horizontal scaffolding poles at identical heights. Accordingly, this requires the use of specific vertical poles and does not enable the height of the clamps to be adjusted. The present invention enables preexisting standard scaffolding poles to be used.
The couplers 10 secure around the outer peripheries of the scaffolding poles and do not require the use of any specialist fittings in order to secure to the scaffolding poles. The outer periphery is defined as being the external surface of the scaffolding poles that extend longitudinally along the poles between the longitudinal
<Desc/Clms Page number 11>
ends of the poles. Prior art couplers for coupling scaffolding poles have required the use of specialist fittings at the longitudinal end of the poles.
Accordingly, the length of the horizontal poles and hence the distance between adjacent vertical supporting poles could not be altered. The present invention secures around the periphery of the horizontal poles such that the horizontal poles can extend therethrough by a varying amount. Accordingly, the distance between adjacent vertical supporting scaffolding poles is adjustable as long as the separation distance is not greater than the length of the horizontal poles. This is advantageous especially for use with safety platforms within construction units since the area within construction units varies and, therefore, the couplers of the present invention enable safety platforms of all shapes and sizes to be made using standard scaffolding poles in order to fit within the required area.
As shown in Figures 1 to 4, the clamp 12 for securing to the first or support scaffolding pole comprises a first jaw member 16 secured to a second jaw member 18. The first jaw member 16 is secured to the second jaw member 18 by a pivot 20 such that the first and second jaw members 16,18 are pivotally movable relative to each other. A locking pin 22 is secured to the first jaw member 16 by a pivot 30. The locking pin 22 extends from the first jaw member 16 and extends through a slot defined in the second jaw member 18.
The locking pin 22 includes a threaded shaft 24 on which a nut 26 and washer 28 are secured. The first jaw member 16, second jar member 18 and locking pin 22 define
<Desc/Clms Page number 12>
an inner retaining space 14 for retaining the support scaffolding pole therein.
In use, the locking pin 22 is disengaged with the slot defined in the second jaw member 18. The first and second jaw members 16,18 are pivotally moved in order to define a receiving area. The first and second jaw members 16, 18 are located around opposite sides of the periphery of the support scaffolding pole. The scaffolding pole is arranged to project through the clamp 10 by a chosen amount. The first and second jaw members 16,18 are then pivotally moved towards each other in order for the locking pin 22 to engage in the slot of the second jaw member 18 and for the nut 26 and washer 28 to locate on the outer side of the second jaw member 18. The nut 26 can then be moved along the threaded shaft 24 in order to reduce the size of the retaining space 14. The retaining space 14 may be substantially circular. As the nut 26 is moved, the first jaw member 16 may pivot relative to the second jaw member 18, and the locking pin 22 may pivot relative to the first jaw member 16.
A shaped abutment surface 17 on the inner periphery of the first jaw member 16 will abut the periphery of the support scaffolding pole and a shaped abutment surface 19 on the inner periphery of the second jaw member 18 will abut an opposed part of the periphery of the support scaffolding pole. The shaped abutment surfaces may be arcuate. In the clamped position, the abutment surfaces 17,19 may define a part of a periphery of a circle. In addition, an inner part 23 of the locking pin 22 may also abut an opposed part of the periphery of the support scaffolding pole. As the nut 26 is tightened the coupler
<Desc/Clms Page number 13>
10 will securely clasp or clamp the periphery of the support scaffolding pole within the retaining space 14.
Once the coupler is secured to the support scaffolding pole, horizontal scaffolding poles can be retained within the second and third clamps 30,32. The operation of the second and third clamps 30,32 is the same as that described for the first clamp 12. Accordingly, the horizontal scaffolding poles can extend through the apparatus by a chosen amount.
The second clamp 30 comprises a first jaw member 40 and a second jaw member 42 pivotally secured to each other through a pivot 44. The second clamp 30 comprises a locking pin 46 extending from a pivot 54 mounted to the first jaw member 40.
The locking pin 46 comprises a threaded shaft 48 along at least a part of its length. The threaded shaft 48 is arranged to cooperate with a nut 50 and washer 52. Again, the inner peripheries of the first and second jaw members 40,42 comprises shaped abutment surfaces 41,43 in order to engage the periphery of a horizontal scaffolding pole.
The third clamp 32 comprises a first jaw member 60 and a second jaw member 62 pivotally secured to each other through a pivot 64. The second clamp 32 comprises a locking pin 66 extending from a pivot 74 mounted to the first jaw member 60.
The locking pin 66 comprises a threaded shaft 68 along at least a part of its length. The threaded shaft 68 is arranged to cooperate with a nut 70 and a washer 72. Again, the inner peripheries of the first and second jaw members 60,62 comprise shaped abutment surfaces 61,63 in order to engage the periphery of a horizontal scaffolding pole.
The second clamp 30 is fixed to the second jaw member 18 of the first clamp 12 by a joint 34 (for example a weld) and the third clamp 32 is fixed to the first jaw member 16 of the first
<Desc/Clms Page number 14>
clamp 12 by a joint 36 (for example a weld). Alternatively, the second and third clamps 30,32 may be pivotally secured to the first and second jaw members 16,18 of the first clamp 12 respectively. The pivotal arrangement enables the clamps to pivot in a plane which enables the clamps to retain scaffolding poles at an angle to the horizontal. Accordingly, the angle between the support scaffolding pole and the first and/or second horizontal scaffolding poles may not be perpendicular.
For example, the first and/or second horizontal scaffolding pole may be required at angle to the horizontal in order to provide a gradually sloping surface.
The first clamp 12 is located centrally with the second and third clamps 30,32 extending on opposing lateral sides of the first clamp 12. However, the first clamp 12 could be located at one lateral side of the coupler 10 such that both the second and third clamps 30,32 are located on the same side relative to the first clamp 12.
As shown in Figures 5 to 9, an assembly comprises a coupler 10, a first scaffolding pole 100, a second scaffolding pole 102 and a third scaffolding pole 104.
The assembly is for use in a safety platform whereby the assembly, or a plurality of assemblies, support a surface spaced from the ground. The surface thereby creates a false floor. The safety platform is for use within building construction units whilst building is in progress. The safety platform thereby reduces the height that workers are at risk from falling. Such safety platforms are especially advantageous for workers working on the roofing structure since usually these workers potentially have the greatest distance to fall. The safety platform provides a continuous or contiguous surface rather than a catchment area provided by a net.
<Desc/Clms Page number 15>
The use of nets does not provide as safe a platform since dropped tools may still pass through the netting and still provide a hazard. In addition, the nets need to be kept well maintained since they may easily degenerate and thereby not provide an effective catchment area.
The safety platform comprises a plurality of support scaffolding poles 100 that extend upwardly from the floor within the construction unit. Alternatively, the support scaffolding poles 100 may be supported on and extend upwardly from beams or joists. The support scaffolding poles 100 have couplers 10 releasably secured thereto at an identical height. The upper extents of the scaffolding poles are covered by covers for example plastic covers 101. The support scaffolding poles 100 extend upwardly from the couplers 10 by a distance less than the width of a scaffolding pole for reasons to be explained later.
A second scaffolding pole 102 is then retained in the second clamp 20 provided by the coupler 10. The second scaffolding pole 102 is arranged to be retained between two couplers 10 located on spaced apart support scaffolding poles 100. The second scaffolding pole 102 is arranged to be substantially perpendicular to the support scaffolding poles 100 such that the support scaffolding poles 100 are substantially vertical and the second scaffolding pole 102 is substantially horizontal.
Similarly, a second scaffolding pole 104 may be retained in the second clamp 32 of each of the couplers 10. Accordingly, a structure is built up having a plurality of scaffolding poles 102,104 extending horizontally, all at the same height. Further scaffolding
<Desc/Clms Page number 16>
poles (not shown) can then be secured across the horizontal scaffolding poles 102,104 using conventional couplers. Scaffolding planks can then be located on the further scaffolding poles. Accordingly, the scaffolding planks will be spaced from the tops of the couplers 10 by a distance substantially equal to the width of a scaffolding pole. Hence, the support scaffolding poles 100 only extend upwardly from the couplers 10 by a distance less than the width of a scaffolding pole from the top support surface of the horizontal poles 102,104.
Finally, boards or sheets, for example, wooden boards, can be located over the scaffolding planks in order to provide a continuous or contiguous surface spaced from the ground within a construction unit in order to provide a safety platform which is adjustable to locate in any size or shaped construction unit using conventional scaffolding poles, scaffolding planks and wooden sheeting.
The coupler 10 is made of metal and preferably of steel.
The coupler may be made of pressed metal or forged (for example drop forged) metal.
Since the size of the retaining space is adjustable in order to clamp the peripheries of the scaffolding poles, the coupler is suitable for all diameter sizes of scaffolding poles.
