Abstract

A flexible arm light fitting (1) comprises a bulb holder (2) connected to a switch box (3) by means of a flexible arm (4), a portion of which is held rigid by a substantially rigid sleeve-like member (5) being slidable along and/or detachable from the flexible arm. The substantially rigid sleeve-like member may be a length of tube of metal or of "rigid" plastics and may be straight or curved lengthwise. In a further embodiment the sleeve- like member may be a split tube so as to be capable of being snapped on to the flexible arm. <IMAGE>

Description

SPECIFICATION Flexible arm light fittings This invention relates to flexible arm light fittings for industrial or domestic use and has for its object the provision of means whereby such lights can be used in a wider range of applications, especially as machine and workbench lights where the length of arm and/or required position of the light may be such that it cannot be held, particularly when the light fitting is subject to vibration from a machine.
According to the present invention, a flexible arm light fitting is provided with at least one substantially rigid sleeve-like member fitted on the flexible arm so as to make rigid a portion thereof.
A particular advantage of the invention is that it enables a longer-than-normal flexible arm to be utilised, but it may be equally advantageous on a normal length flexible arm by preventing drooping, especially when subjected to vibration.
The substantially rigid sleeve-like member may be slidable along and/or detachable from the flexible arm, as long as it has a sufficient grip on the flexible arm not to be dislodged by vibration or accidentally. Thus, the substantially rigid sleevelike member may be a length of tube (e.g. of metal or "rigid" plastics material) slidable -- when required -- along the flexible arm and fitted on it prior to fitting of an end member (such as a bulb) holder or a switch box), so as to remain captive; or the substantially rigid sleeve-like member may be a split tube (e.g. of metal or "rigid" plastics material) capable of being snapped on to the flexible arm; or the substantially rigid sleeve-like member can be a spring (e.g., of metal or plastics coated metal or "rigid" plastics material); and the substantially rigid sleeve-like member may be straight or curved lengthwise.
Again, the substantially rigid sleeve-like member may consist of two tubular portions (which may be split so as to be capable of snapping on to the flexible arm) connected by a bar portion, which may be straight or curved or beng to provide axial alignment or any desired angle between the tubular portions, or the tubular portions may be axially inclined with respect to a straight bar portion. This form of sleeve-like member may also be formed of metal, which may enable a curvature of or bend in the bar portion to be varied, or it may be formed of "rigid" plastics material.
The flexible arm may be provided with more than one substantially rigid sleeve-like member, connected together by a coupling member or members provided with sockets into which adjacent tubular ends of the sleeve-like members are pushed.
A tubular substantially rigid sleeve-like member may be provided with a compression fitting at one end to enable the tubular sleeve-like member to be locked to the flexible arm in any desired position. Alternatively, or in addition, an end member (such as a bulb holder or a switch box) may be provided with a socket forming a coupling member into which the adjacent end of the (or a) sleeve-like member may slide.
A number of embodiments of the invention will now be described by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a flexible arm light fitting showing substantially rigid sleeve-like member fitted on the flexible arm; Figures 2 to 4 are fragmentary side elevations of the flexible arm of Figure 1 showing various embodiments of the substantially rigid sleeve-like member in accordance with the invention; Figure 5 is a fragmentary side elevation of the flexible arm of Figure 1 showing two tubular portions connected by means of a bar; Figure 6 is a fragmentary side elevation of the flexible arm of Figure 1 showing two tubular portions connected by means of socketed coupling member;; Figure 7 is a fragmentary side elevation of the flexible arm of Figure 1 showing the substantially rigid sleeve-like member locked to the flexible arm by means of a compression fitting; and Figure 8 is a fragmentary side elevation of the flexible arm of Figure 1 showing the substantially rigid sleeve-like member held in the coupling member of switch box.
In Figure 1 a flexible arm light fitting 1 comprises a bulb holder 2 connected to a switch box 3 by means of a flexible arm 4, a portion of which is held rigid by a substantially rigid sleevelike member 5.
In Figure 2 the substantially rigid sleeve-like member 5 is curved and in Figures 3 and 4 the substantially rigid sleeve-like members 5 comprise respectively a straight split tube and a curved split tube.
In Figure 5 the substantially rigid sleeve-like member 5 is comprised of two tubular portions 6 (which are split so as to be capable of snapping on to the flexible arm) connected by a bar portion 7, which may be straight to provide axial alignment or curved or bent (as shown) to provide any desired angle between the tubular portions, while in Figure 6 two tubular portions 8 are connected together by a coupling member 9 with sockets 10 into which adjacent tubular ends of the tubular portions are pushed.
In Figure 7 the substantially rigid sleeve-like member 5 is provided with a compression fitting 11 at one end to enable the tubular sleeve-like member to be locked to the flexible arm in any desired position, while in Figure 8 an end member, such as a switch box 12, is provided with a socket 1 3 forming a coupling member into which the adjacent end of the sleeve like member can slide.
