Definitions
- This invention relates to suspension clamps for clamping elongate flexible members such as. for example, cables
- cables should be interpreted as including among other things power cables, optical cables, ropes, and wires
- Suspension clamps should also cater for cables of different sizes
- the present invention provides a suspension clamp for elongate flexible members such as. for example, cables, the clamp comprising: - ⁇ ) a saddle in which the elongate flexible member may sit, ii) a mounting to support the saddle with respect to a fixture, iii) a closure latch to restrain the elongate flexible member in the saddle iv) a resilient member mounted to the closure latch and having a bottom face adapted to clamp an elongate flexible member positioned within the saddle when the closure latch is closed.
- a suspension clamp as aforesaid wherein the closure latch is pivoted at a first side of the saddle.
- a suspension clamp as aforesaid wherein a free end of the closure latch is a snap-fit with a second side of the saddle
- a suspension clamp as aforesaid wherein the resilient member is mounted as a sliding fit with respect to the closure latch.
- the mounting comp ⁇ ses one or more ringlets
- the mounting comp ⁇ ses one or more brackets
- a suspension ciamp wherein the upper surface of the saddle which provides support for the elongate flexible memoer is generally arcuate
- a suspension clamp where the lower surface of the resilient member which clamps the elongate flexible member is generally arcuate
- Fig. s an end view of one form of a suspension clamp in accordance with the present nvention
- Fig. 2 s a side view in broken section of the suspension clamp of Fig. 1
- Fig. 3 s a plan view of the suspension clamp of Fig. 1.
- Fig. 4 s an end view of another form of suspension in accordance with the present nvention,
- Fig. 5 s a side view in broken section of the suspension clamp of Fig. 4
- Fig. 6 s a plan view of the suspension clamp of Fig. 4
- Fig. 7 s an end view of a further form of clamp showing a method of mounting same
- suspension clamps in accordance with the two examples illustrated are generally indicated by arrow 1 and comprise a saddle 2, a mounting generally indicated by 3 by which the clamp can be supported with respect to a fixture, (not shown) and a pair of closure latches generally indicated by arrow 4 secured to the saddle 2, said closure latches 4 each mounting a resilient member 5 having a bottom face 6 adapted to clamp an elongate flexible member such as a cable in the saddle 2 when the closure latch is closed (as in the illustrated examples).
- a resilient member 5 having a bottom face 6 adapted to clamp an elongate flexible member such as a cable in the saddle 2 when the closure latch is closed (as in the illustrated examples).
- the resilient members 5 allow elongate flexible members of a range of diameters to be secured in the clamp, the variation in diameter being taken up by the resilience of the resilient members.
- closure latches 4 are pivoted at a first side 7 of the saddle 2. It will be clear to the skilled reader that the closure latches need not be so pivoted and may, for example, comprise detachable elements secured to the resilient members.
- each closure latch 4 is a snap-fit with the other side 9 of the saddle 2. It will be clear to the skilled reader that other means of securing the free end 8 are usable such as, for example, a secondary latch to interengage with and restrain the closure latch.
- the resilient member 5 is a sliding fit in relation to the closure latch 4 being removable therefrom.
- the resilient member may in some circumstances by fixedly secured to the closure latch, for example, the closure latch and resilient member together may form a removable, replaceable, disposable part of the clamp.
- the mounting 3 by which the saddle can be supported with respect to a fixture can comprise ringlet(s) 10 or bracket 1 1 but other mountings can readily be used.
- Fig 7 shows an arrangement in which the saddle 2 carries flanges 19 either of which as required can engage as a snap fit in a slot 20 in bracket 21, spring arm 22 holding the flange securely
- the upper surface 12 of the saddle 2 is arcuate but angular or straight surfaces may be used An arcuate surface is preferred so that the elongate member leaving the clamp is not kinked by the end edges 18 of the saddle 2.
- the bottom face 6 of the resilient member 5 may also be arcuate but angular or straight surfaces may be used. It is however preferable that the bottom face 6 of the resilient member 5 correspond generally in form to the upper surface 12 of the saddle 2.
- the saddles 2 which may be formed in plastics (such as by injection moulding) or metal have an arcuate base face 12, side walls 14 which are curved and in each case the latch comprises a bar 15 which has one end pivoted at side 7 of the saddle, free ends 8 of latch engaging in a snap-fit arrangement with the other side 9 of the saddle.
- Each latch 4 can be mounted or otherwise formed in a resilient material and the snap-fitting can be provided by virtue of the complementarily stepped edges of the free ends 8 of each latch and side 9 of the saddle.
- the resilient members 5 (which may be formed in rubber or another resilient material) each have tails 16 which are sliding fit in apertures 17 of the latches.
- the tails 16 enable the resilient members 5 to be removed to ease stringing of the elongate flexible members in the saddles.
- clamps can be suspended or secured with respect to a fixture in any manner, e.g. by the use of mountings such as pivotally mounted eyelets (Figs. 4 to 6), brackets 11 (Figs. 1 to 3), or brackets 21 (Fig.7) as in the arrangements indicated or in other suitable arrangements.
- mountings such as pivotally mounted eyelets (Figs. 4 to 6), brackets 11 (Figs. 1 to 3), or brackets 21 (Fig.7) as in the arrangements indicated or in other suitable arrangements.
