Definitions

  • This invention relates to a clamp. It is particularly concerned with a clamp whereby planks can be secured to a scaffold structure.
  • a clamp for securing a pair of planar members to a cross member transverse the pair by way of a gap between the pair comprising:
  • a spring member mounted so as to extend in part through the plate by way of the hole to provide on the second side of the plate a first, hooked, section of the member for engagement with a cross member;
  • the spring member having a second section linked to the first section by way of a first angle of inflection, the second section being of similar length to the distance along the gutter between the hole and the detent; the second section being linked to a third section by way of a second angle of inflection; the first and second angles of inflection lying in the same plane; the spring member serving to engage with the plate member between: a locked configuration in which member lies with the first angle of inflexion in the hole to cause the first section to lie with its first, hooked, section opening towards the plate; the second section of the member lies in the gutter and that part of the spring member making up the second angle of inflection serves to engage the detent so as to retain the spring member in a locked configuration with the plate; and an unlocked configuration in which when the member is released from engagement between the second angle of inflection and the detent
  • the present invention serves to provide a clamp having a secure and positive locking action while being configured as to provide a minimum projecting profile so that the risk of tripping is reduced. It further provides a clamp which is readily used for demountably but safely securing scaffolding planks to scaffold poles in the course of building a scaffold structure. It also provides for the ready, though not inadvertent, release of a clamp from its working position when the associated scaffold pole structure is being modified or dismantled.

  • Figure 2 is a side view of a spring member for use in conjunction with the plate of Figure 1;
  • Figure 3 shows is a plan view of a region of a scaffold structure in which the components of Figures 1 and 2 are utilised;
  • Figure 4 is a sectional elevation on section IV-IV of Figure 3.
  • Figure 5 is a perspective view of a second embodiment
  • Figure 6 is a perspective view of a third embodiment- Figure 7 is a view of the third embodiment of Figure 6 when viewed from its opposite side;
  • Figure 8 shows the third embodiment in use for face boards in a scaffold structure
  • Figure 9 shows the third embodiment in use for toe boards in a scaffold structure
  • Figure 10 shows the use of the second embodiment of Figure 5 for use to hold down decking boards in a scaffold structure
  • Figure 11 shows the use of the second and third embodiments in combination in a scaffold structure.
  • Figures 1A, IB and 1C show plate 11 having an upper face 12 and a lower face 13.
  • the plate 11 includes a channel 14 which when viewing the upper face 12 is concave.
  • the channel 14 has sides 14A, 14B projecting upwardly from plane 15 in which the major part of upper surface 12 lies.
  • the channel 14 includes towards its left hand end (as viewed in Figures 1A, IB) a hole 16 extending through the plate 11.
  • the channel 14 is provided at its right hand end (as viewed in Figures 1A, IB) with a detent 17.
  • Hole 16 is distant from detent 17 by an amount L.
  • Figure 2 shows a spring member 21 is of spring wire.
  • Member 21 has a first section 22 in form of a hook with an internal diameter 23 corresponding to a lightly smaller diameter (D) than that of a scaffold pole (see Figure 4) to which the plate 11 in conjunction with member 21 is to be coupled as will be described hereafter.
  • Outer end 26 of first section 22 is formed to provide a retaining lip with an undistorted clearance C slightly less than the outside diameter of a scaffold pole with which it is to be used.
  • Second section 27 is straight with a length LI and is linked to first section 22 by way of a first inflexion 28 in the form of a short curve providing for the first section 12 to lie at right angles to, but in the same plane as, the second section 27.
  • Third section 29 provides a clip configuration on opposite end 30 of the member 12 to the first section 22.
  • a second inflexion section 31 is provided with a part 32 projecting towards the first section 12 so that length L2 is slightly shorter than length LI.
  • Figures 3 and 4 variously show plate 11 and member 21 in combination providing for the retention of scaffold planks 31, 32 on a scaffold pole 33.
  • Scaffold pole 33 having been secured in position in a scaffold planks 31, 32 are laid side by side on the pole to leave a parallel sided gap 34 between them and at right angles to the pole 13.
  • Plate 11 is then placed so that the downwardly projecting part of the plate 11 formed by the underside of channel 14 seats in the gap 34.
  • the member 21' (shown in broken outline in its unlocked configuration) with first inflexion 28 in the hole 16.
  • the member 21' is then deflected about the first inflexion 28 in the hole 16, such as by pressing the second section 27' of the member 21' with the foot, so that outer end 26 of member 21' is passed beneath the scaffold pole 33 as shown in Figure 4.
  • the second section 27' of member 21 is then aligned above the channel 14 and then pressed down into the channel so that part 32 contacts and then deflects to slip round and thereafter engage the detent 17 in the working configuration of the member 21 shown in full outline.
  • the first end 26 of the member 21 is driven around and so engage the scaffold pole 33. In this way the neighbouring edges of the planks 31, 32 beneath the plate 11 are demountably secured in place on the pole 33.
  • the second section 27 of the member 21 is recessed in the channel 14 and the third section 29 is located within the gap 34.
  • the upper side of the plate 11 is of negligible height above the level of the planks engaged by the plate and present little obstruction to the passage of feet or equipment over the planks when secured.
  • the clamp is readily disassembled when the planks are to be dis-engaged from the scaffold pole 33 such as by levering up the third section 29 of the member 21 out of the gap 34 so releasing the first section 22 from engagement with scaffold pole 33.
  • the plate 11 and member 21 are then readily lifted from the planks.
  • Figure 5 shows a developed version of the first embodiment.
  • Plate 51 is similar in form to plate 11 of Figures 1, 4 but differs from plate 11 in having holes H in each corner to enable the plate 51 to be secured, such as by nails, to a decking plank as will be described hereafter in connection with Figures 10, 11.
  • the plate 51 is provided with channel 54 and an aperture 56 (in contrast to the hole 16 of Figure 1).
  • Detent 57 serves to engage minor hook section 52 of clip C which is shown with central section 55 seated in channel 54 and with major hook section 58 in its working position extending on the same side of plate 51 as minor hook section 52.
  • Figure 6 shows from the right hand side a plate 61 with a left side downwards extension 62 and a re-entrant lip 63 to proved a J shaped recess J.
  • the plate 61 contains channel 64 and an aperture 66.
  • Detent 67 serves to engage minor hook section 60 of clip C which is shown with central section 68 seated in channel 64 and with major hook section 69 in its working position extending on the same side of plate 61 as minor hook section 60.
  • a pair of holes H are provided to enable the plate 61 to be readily secured to a plank or other planar member on which it is mounted.
  • Figure 7 shows the embodiment of Figure 6 from the opposite side to that shown in Figure 6.
  • Figures 8 and 9 show the embodiment of Figures 6 and 7 in use, respectively, to secure face and toe boards.
  • Figure 8 shows a face board 80 resting on a horizontal scaffold pole 81.
  • Plate 61 is secured by nails through holes H to face board 80 which projects some way into J- shaped recess J.
  • Clip C is shown in its closed position with its minor hook section 60 clipped over detent 67 and major hook section 69 anchoring the combined plate and clip in place around horizontal pole 81.
  • Figure 9 shows a toe board 90 clipped to a vertical scaffold pole 91.
  • Plate 61 is secured by nails through holes H to toe board 90 which projects some way into J-shaped recess J.
  • Clip C is shown in its closed position with its minor hook section 60 clipped over detent 67 and major hook section 69 anchoring the combined plate and clipped in place around vertical pole 91.
  • FIG. 10 shows several clamps 101, 102, 103 according to the second embodiment in use to secure a parallel series of decking planks 105, 106, 107, 108 (partly) to a horizontal scaffold pole 109.
  • Each of the clamps 101, 2,3 are shown in their closed position and each plate seats on two planks (for example plate 101A lying over planks 105, 106) to which the plate is secured by holes H.
  • the figure demonstrates the snug fit of the clamps to the boards with the clips readily accommodated in the gap between each pair of decking planks. It will also be apparent that in the event a clamp is not fully closed (hat is to say the clip is not located with its centre section seated in the channel of its associated plate) then the fact will be readily apparent with even a brief viewing of a given region of the structure.
  • Figure 11 shows a decking assembly with clamps 110, 113 according to the second embodiment and clamps 111 and 112 according to the third embodiment providing for the retention of decking planks 114, 115 to a horizontal scaffold pole 116.
  • the planks 114, 115 are spaced apart by vertical scaffold poles 117, 118.
  • the size of the clamps are related to a modular size based on the outside diameter of a scaffold pole.
  • the overall width of clips 111, 112 provides for them fitting within the gap between the planks 114, 115 without contact between them.
  • the width of the plates of clips 110, 113 and the location of the holes H provides for a pair of such plates to be bolted together along their longer sides so that a gap established between planks by a vertical scaffold pole can be readily bridged by a bolted together pair of plates.
  • the plate can be made in a double ended form with a further longitudinal aperture being provided in the channel lying on the longitudinal axis of the plate and towards the second end of the plate, a further detent on the plate on the longitudinal axis and at or near the first end of the plate, and the longitudinal axial distance between the edge of the further aperture and the further detent being of the given length.
  • the aperture and the detent on the one hand and the further aperture and the further detent on the other hand are located symmetrically on the plate.
  • This doubled arrangement is particularly applicable to the version of the third embodiment described in connection with Figures 6 and 7. As shown in Figures 6 and 7 these are handed versions with side extension 62 and side lip 63 on what can be said to be the left hand side.
