  • means for suspending equipment from an overhead structural member comprises a suspension strand and a locking device having twin bores at least one of which is associated with wedging means (e.g. a ball, roller or wedge) preventing withdrawal of the free end of the suspension strand; (i.e.
  • a hole is provided through the overhead member, the toggle plate is angled into dose lengthwise alignment with the suspension strand adjacent the nipple, the toggle plate is passed with the nipple through the hole in the overhead member, and the toggle plate is realigned predominantly perpendicularly to the suspension strand and bridging the topside of the hole, whereafter the free end of the strand is passed through one bore of the locking device, then through an eye provided on the equipment or passed round the equipment, and through the other bore of the locking device wherein the strand is secured by the wedging means.
  • a hole is provided in the equipment to be suspended, or a supporting member therefor, the angled toggle plate is passed with the nipple through the hole and realigned predominantly perpendicularly to the suspension strand and bridging the underside of the hole, whereafter the free end of the strand is passed through one bore of the locking device, then through an eye provided on the overhead structural member or passed over the member, and through the other bore of the locking device wherein the strand is secured by the wedging means
  • the level at which the equipment is suspended can be adjusted upwards by pulling the locking device upwards or downwards, as the case may be, or by pulling the free end of the suspension strand further through the locking device, which may be provided with temporary release means for its wedging means to enable the level at which the equipment is suspended to be adjusted downwards.
  • the suspension strand may be a length of wire or wire rope, or of any other suitable material, with the nipple formed by a separate member with a hole in which the end of the strand is secured by swaging the whole or part of the separate member, which may be formed with an enlarged formation to abut a substantial area of the toggle plate on each side of the aperture.
  • Each bore of the locking device may be associated with wedging means, so that the locking device can be used either way up.
  • An equipment suspension kit in accordance with the invention comprising a suspension strand with a nipple, a toggle plate with an aperture, and a locking device, as aforesaid, may also include plastics sleeving for slipping over part of the suspension strand expected to contact the equipment to be suspended, e.g. to minimise vibration or noise; and a tensioning tool, such as a blind rivetting tool, may be included for tensioning the suspension strand by application of the tool to the free end of the suspension strand after it has passed through the second bore of the locking device.
  • a tensioning tool such as a blind rivetting tool
  • FIG. 1 is a side elevation of a suspension strand with a nipple and toggle plate in accordance with the invention
  • FIG. 2 is an elevation of the upper end of the strand of FIG. 1 as seen from the left hand side thereof;
  • FIG. 3 corresponds to FIG. 2 but shows the nipple and toggle plate being passed through a hole in an overhead structural member
  • FIG. 4 corresponds to FIG. 3 but shows the toggle plate orientated to prevent withdrawal of the nipple through the hole;
  • FIG. 5 is a downward extension of FIG. 4 showing one method in accordance with the invention by which the strand can be used with a locking device to suspend equipment from the overhead structural member,
  • FIG. 6 is an enlarged longitudinal section through the locking device
  • FIG. 7 is a small scale elevation showing a pair of suspension strands as in FIGS. 1 to 4 and a pair of locking devices as in FIGS. 5 and 6 being used in another method in accordance with the invention.
  • FIGS. 8 and 9 are further small scale elevations illustrating two further methods of suspending equipment from overhead structural members in accordance with the invention.
  • a suspension strand 10 formed by a length of wire rope has a nipple 11 at one end, and a toggle plate 12 having a length appreciably greater than its width has an aperture 13 elongate in the lengthwise direction of the toggle plate but of a width preventing passing of the nipple 11 through the aperture, the free end 14 of the strand being passed through the aperture until the toggle plate lies captive adjacent the nipple.
  • the toggle plate 12 is shown angled into close lengthwise alignment with the strand 10 adjacent the nipple 11 , to enable the nipple and the toggle plate to be passed through a hole 15 in an overhead structural member 16 , as illustrated by FIG. 3, and then the toggle plate is realigned predominantly perpendicularly to the strand and bridging the topside of the hole, as shown in FIG. 4, whereafter the free end 14 of the strand is passed through one bore 17 A of a locking device 18 (see FIGS. 5 and 6) having twin bores 17 A, 17 B associated with wedging means 19 A, 19 B preventing withdrawal of the free end of the strand in the opposite direction to insertion. Further, as illustrated by FIG. 5, the free end of the strand can be passed through an eye 20 provided on equipment 21 to be suspended and through the other bore 17 B of the locking device 18 , to secure the equipment suspended from the overhead structural member.
  • the nipple 11 is formed by a separate member with a hole 22 in which the end of the strand 10 is secured by swaging part of the separate member, the remainder of which is an enlarged formation 23 to abut a substantial area of the toggle plate 12 on each side of the aperture 13 .
  • the wedging means 19 B in the bore 17 B of the device in the disposition shown in FIG. 5 would suffice to secure the equipment 21 suspended from the overhead structural member 16
  • the provision of wedging means in both bores 17 A, 17 B is preferred so that the locking device 18 can be used either way up.
  • the level at which the equipment is suspended can be adjusted upwards by pulling the connector upwards or by pulling the free end 14 of the strand further through the locking device, e.g. by means of a tensioning tool (not shown but, for example, a blind rivetting tool).
  • a tensioning tool not shown but, for example, a blind rivetting tool
  • the locking device may be provided with temporary release means for its wedging means, as will be exemplified in the following detailed description of the locking device.
  • the wedging means 19 A, 19 B comprise wedges slidable along respective channels 24 A, 24 B in the body 25 of the locking device 18 , each channel converging at an acute angle to and into communication with a respective one of the twin bores 17 A, 17 B (which are separated by a thin wall 26 ) towards an inlet end 27 A or 27 B of that respective bore, the wedges 19 A, 19 B being provided with transverse ribs 28 (or teeth or other surface formations) for gripping engagement with the strand 10 (when inserted) under the urge of compression springs 29 A, 29 B between the wedges and recessed abutments 30 A, 30 B adjacent outlet ends 31 A, 31 B of the respective bores 17 A, 17 B.
  • Apertures 32 A, 32 B in the body 25 of the locking device 18 each have an inner end opening into a respective channel 24 A or 24 B and is available as a guide for a separate tool(not shown) pushed into the channel to move the respective wedge against its spring urge to enable the strand to be freed temporarily for adjustment of the position of the locking device with respect to the strand and thereby also the level of the suspended equipment 21 .
  • FIG. 7 an item of equipment 21 or a support for an item of equipment is shown suspended by a pair of strands 10 and a pair of locking devices 18 but, instead of providing eyes on the equipment, the free ends 14 of the strands are passed round the equipment after passing through the bores 17 A in the devices 18 and before passing through the bores 17 B, lengths of plastics sleeving 33 being slipped over parts of the suspension strands where they would otherwise contact the equipment, e.g. to minimise vibration or noise.
  • a hole 34 is provided in the item of equipment 21 , the angled toggle plate 12 on the strand 10 is passed with the nipple 11 through the hole and realigned predominantly perpendicularly to the strand and bridging the underside of the hole, whereafter, in FIG. 8 the free end 14 of the strand is passed through one bore 17 A of the device 18 , then through an eye 35 provided on the overhead structural member 16 and through the other bore 17 B of the locking device wherein the strand is secured by the wedging means, while in FIG. 9 the strand is passed over the member 16 after passing through the bore 17 A in the device 18 and before passing through the other bore 17 B of the locking device.
  • the level at which the equipment is suspended in the manner of FIG. 8 or FIG. 9 can be adjusted upwards by pulling the locking device 18 downwards or by pulling the free end 14 of the suspension strand 10 further through the locking device.
