This invention has particular application to anchors for sinuous springs.
Such anchors have hitherto taken one form comprising an element which is nailed or stapled to a part of the frame of an article of furniture. The element is provided with one or more (usually two) hook formations which engage the spring. In another form, an element was made of spring steel wire comprising a base from which arise a pair of cranked arms, between the base and the free ends at an angle greater than 90, the free ends being also bent at about right angles. The cranked base end engages the spring and the bent free ends engage inholes provided in the frame. These holes require to be accurately located and involve considerable effort and equipment.
It is an object of the present invention to provide an element which will not require holes to be formed in the frame in order that it may be located thereon, and which will also not involve any nailing, stapling or the like in order to fix it to the frame.
According to the present invention, there is provided an article of furniture comprising a structural member to which is attached at least one element under tension, for example, a spring, an attachment member for attaching the element to the structural member, the attachment being of wire formed into a U shape, having a base and two arms arising therefrom, the arms being cranked at points equisistant from the free ends through equal angles not less than 90, the free ends of the arms being looped back on themselves to constitute formations adapted to engage the member under tenslon.
Further according to the invention, there is provided an article of furniture comprising a structural member to which is attached at least one element under tension, for example, a spring, the element being attached to the structural member by means of an attachment member of wire and in the form of a U having a base and two arms arising therefrom, the arms being cranked at points equidistant from the free ends through equal angles not less than 90, the free ends of the arms being adapted to engage the element under tension and the portion of the attachment member comprising the base and the arms up to the points at which they are cranked being adapted to engage a shoulder formed in the structural member.
According to one aspect of the invention,the shoulder constitutes one face of a channel formed in the structural member.
According to a feature of the invention, the base of the U is substantially straight.
The invention is further discussed with reference to the accompanying drawing in which FIG. 1 is a perspective view of part of a bed frame 10 to which are attached at intervals a number of spring 12 and FIG. 2 is an end view thereof. Part of the bed frame is shown cutaway at 14.
The springs 12 are attached to the frame 10 by means of clips 16 which are of spring steel wire and are substantially of the shape of a U having a straight base 18 and arising therefrom two substantially identical arms 20. A short distance from the base 18, each arm 20 is cranked as at 22 through an angle A not less than and advantageously somewhat more than that.
The free ends of the arms are looped around as at 24 to provide hook formation which the springs 12 can engage.
The frame 10 is formed with a channel 26 which is angled complementally to the angle A of the cranked arms, and the lower portion of the clip, thus is received neatly in this channel.
The efficacy of the invention lies in the fact that it is a simple matter to form the channel 26 in the frame 10 simply by passing the frame member over a suitably angled circular saw.
The invention has application to any member under tension attached to the clips 16 instead of the springs 12.
I claim:
1. An article of furniture comprising a structural member to which is attached at least one coil tension spring under tension, the spring being attached to the structural member by means of an attachment member of wire and in the form of a U having a base and two arms extending from the base, the arms being cranked at points equidistant from the base of the U through angles not less than 90, the free ends of the arms being formed as hooks adapted to engage the spring, and the portion of the attachment member comprising the base and the arms up to the points at which they are cranked being adapted to engage a slot formed in the structural member.
2. An article of furniture according to claim 1 in which the free ends of the arms of the attachment member are looped back on themselves.
3. For an article of furniture as claimed in claim I, an attachment member of wire and in the form of a U having a base and two arms extending from the base, the arms being cranked at points equidistant from the base of the U through equal angles not less than 90 but less than the free ends of the arms being looped back on themselves to form hooks, and the arms being substantially straight between the base and the points at which the arms are cranked.

Claims (3)

1. An article of furniture comprising a structural member to which is attached at least one coil tension spring under tension, the spring being attached to the structural member by means of an attachment member of wire and in the form of a U having a base and two arms extending from the base, the arms being cranked at points equidistant from the base of the U through angles not less than 90*, the free ends of the arms being formed as hooks adapted to engage the spring, and the portion of the attachment member comprising the base and the arms up to the points at which they are cranked being adapted to engage a slot formed in the structural member.
2. An article of furniture according to claim 1 in which the free ends of the arms of the attachment member are looped back on themselves.
3. For an article of furniture as claimed in claim 1, an attachment member of wire and in the form of a U having a base and two arms extending from the base, the arms being cranked at points equidistant from the base of the U through equal angles not less than 90* but less than 180*, the free ends of the arms being looped back on themselves to form hooks, and the arms being substantially straight between the base and the points at which the arms are cranked.
