Abstract

The clip has a wire loop (1) one end being hooked and driven into a blind hole (6) in the tip of a tightening screw (7), which can be rotated within a tapped hole (8) in the screw bearing, the latter having two insertion holes (9) spaced some distance apart, the other end (2) of the wire loop being hooked and selectively and releasably engaged in one insertion hole (9) or the other, according to whether the hose has a right- or left-handed helix. The loop wire (1) adjacent the releasable end (2) can be laid in one or other of guide recesses (10) in the side of the screw bearing adjacent the wire loop. <IMAGE>

Description

SPECIFICATION Wire hose clip for right. and left-handed helix hoses This invention relates to a wire hose clip for rightand left-handed helix hoses, having a wire loop which is~passed round the hose requiring clipping, with one, first end of the loop wire anchored in a screw bearing, and with a hook on the other, second end, which second end is passed through a hole in the screw bearing and driven under pre-stress into a blind hole in the tip of the tightening screw, while the tightening screw can be rotated within a tapped hole in the screw bearing and substantially tangentially to the wire loop.

There is a known wire hose clip of this type, in which the one end of the wire loop is permanently anchored in the screw bearing and the other, hooked, end is permanently engaged in the screw bearing because it cannot be withdrawn through the hole therein. Difficulties frequently arise in assembly operations on this score, since the known wire hose clip can only be drawn over a free end hose end. Moreover, the tightening screw has a special reinforcing bush on its tip, the blind hole for the anchored end of the wire loop being provided in the bush. Finally, the known embodiment cannot be used directly for both right- and left-handed helix hoses without further preparation.

The same disadvantages arise with other known wire hose clips, in which the ends of the wire loop are formed into eyelets and pushed on to the tightening screw, one bearing against the head of the screw while the other bears against a nut, so that as the tightening screw is rotated the permanently closed wire loop is either shortened or lengthened.

The object of the invention is to provide a wire hose clip of the type initially described that can be passed round the hose in an easy manner, even when there is no free end, and furthermore can be fitted on either right- or left-handed helix hoses with equal ease.

According to the present invention, in a wire hose clip of the type initially described the screw bearing has two insertion holes spaced at a given distance apart in a plane at right angles to the general plane of the wire loop, to take a hooked releasable anchoring first end of the wire loop, and this hook can be engaged interchangeably in one or the other insertion hole from the side of the screw bearing remote from the tip of the tightening screw with the blind hole.

Thus permanent anchoring of the first end of the wire loop has been abandoned, and so the hooked releasable anchoring end can easily be released from the screw bearing and passed round the hose body during the assembly operations. The releasable anchoring end is then engaged in one insertion hole or the other, depending on whether the hose has a right- or left-handed helix.

Further and preferred features of the invention will now be described, thus, the loop wire adjacent the realasable anchoring end can be laid on one or other of open-ended guide recesses in the side of the screw bearing adjacent the wire loop, so that it is satisfactorily located on the screw bearing yet can be removed at any time during the assembly operations, so that the wire loop can be opened out for passing round a hose. The guide recesses are preferably spaced apart like the insertion holes in the plane at right angles to general plane of the wire loop. The insertion holes and the guide recesses are preferably located on either side of the tightening screw symmetrically in planes parallel to the general plane of the wire loop.

The blind hole in the tip of the tightening screw preferably receives the, permanently anchored, hooked end of the wire loop directly into it, so that the usual reinforcing bush with its own blind hole is no longer needed on the tip of the tightening screw.

The advantages accruing from the invention are to be seen substantially in that it provides a wire hose clip which offers outstandingly simple assembly possibilities on the one hand and can be used equally well on right- and left-handed helix hoses. Relatively simple means are used and there are in fact fewer components than have hitherto been required.

An embodiment of the invention will now be described, by way of example, only, with reference to the accompanying drawings, in which:~ Figure 1 is a fragmentary side elevation of a wire hose clip in accordance with the invention, the tip of its tightening screw being shown in axial section; Figure 2 is an elevation from the left hand end of Figure 1; and Figure 3 corresponds to Figure 1 but with the releasable enchoring end of the wire loop released.

In the drawings, a wire hose clip, for right- and left-handed helix hoses, has a wire loop 1 which is passed round the hose (not shown) requiring clipping, with one, first end 2 of the loop wire anchored in a screw bearing 3, and with a hook on the other, second end 4, which end is passed through a hole 5 in the screw bearing 3 and driven under pre-stress into a blind hole 6 in the tip of tightening screw 7. The tightening screw 7 can be rotated within a tapped hole 8 in the screw bearing 3 and substantially tangentially to the circular wire loop 1. On rotating the tightening screw 7, the wire loop 1 is either lengthened or shortened, depending on the direction of rotation. The screw bearing 3 has two insertion holes 9 spaced at a given distance one from the other in a plane at right angles to the loop, to take the releasable anchoring end 2 of the wire loop 1.This anchoring end 2 is also hooked and the hook can be engaged interchangeably in one or the other insertion hole 9 from the side of the screw bearing remote from the second hooked end 4 of the wire loop 1 in the blind hole in the tip of the tightening screw 7. Thus the ends 2 and 4 of the wire loop 1 overlap in the region of the screw bearing 3.

The loop wire adjacent the anchoring end of the wire loop 1 is laid in one or other of open-ended guide recesses 10 on the side of the screw bearing 3 adjacent the wire loop and matching the insertion holes 9. Thus the guide recesses 10 are spaced apart like the insertion holes 9. Moreover, the insertion holes 9 and the guide recesses 10 are located on either side of the tightening screw 7, symmetrically in planes parallel to the plane of the wire loop. The second hooked end 4 of the wire loop 1 is inserted directly into the blind hole 6 formed in the tip of the tightening screw 7. The screw bearing 5 has the known U-shaped body form with the two arms in which the holes 5, 8 and 9 are provided disposed relatively close to each other, and with the guide recesses 10 formed in the U-base.
