DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an arrangement for open profile lengths intended to permit these to be connected together to produce a channel structure which is closed around its periphery.
The principal object of the present invention is, in the first place, to make available an arrangement of the kind referred to above, which, amongst other things, permits profile lengths of identical execution to be connected together to form a closed channel structure which lends itself to use in lighting applications, for example, without the need for the production and storage of profile lengths of different kinds, and which also lends itself to being executed with a desired external form.
Said object is achieved by means of an arrangement in accordance with the present invention, which is characterized essentially in that two profile lengths of mutually identical execution, each of which has its own flange with the desired external form and a number of connecting elements projecting from a common base, are so arranged, with their channel-shaped spaces facing towards one another, as to be connected together through the interaction between said flanges and connecting elements.
The invention is described below as a preferred illustrative embodiment, in conjunction with which reference is made to the drawings, in which
FIG. 1 shows a perspective view of a profile length in accordance with the present invention, viewed at an angle from below;
FIG. 2 shows a perspective view of a upturned profile length, viewed at an angle from above;
FIG. 3 shows a section through two assembled profile lengths;
FIG. 4 shows a channel section attached to a support;
FIG. 5 shows a perspective view of a channel section incorporating LEDs;
FIG. 6 shows a further example of a channel section fitted with LEDs, viewed at an angle from above; and
FIG. 7 shows said channel structure viewed at an angle from below.
So-called "open" profile lengths 1, 2, which can exhibit a desired length and can consist of aluminium or some other suitable metal, or even of a plastic material, and which are so arranged as to be capable of being connected together to produce a "closed" channel structure 3 along the effective external periphery of the profile lengths, comprise an arrangement 4 which permits two profile lengths 1, 2 of mutually identical execution to be connected together to produce a channel structure 3 of the aforementioned kind, thereby avoiding the need for the production and storage of profile lengths of different kinds. Said arrangement 4 involves each profile length 1, 2, which can be produced by a previously disclosed method, for example by extrusion, having its own external flange 5 with the desired external form which it is wished to impart to the assembled closed channel structure 3 and also a number of outgoing connecting elements 7, 8, 9 projecting from a common base 6 for the profile length.
Two mutually identical profile lengths 1, 2 are thus so arranged as to be capable of being connected together, in the positions I and II in which they are turned so that their channel-shaped spaces 10 face towards one another or at least face towards a common imaginary plane 11 situated between said two profile lengths 1, 2, through the interaction between said flanges and outgoing connecting elements 5, 7; 8, 9; 9, 8; 7, 5.
Said formed flange 5 may appropriately exhibit rounded form, as illustrated in the drawings, or may have some other angled form which deviates from straight form, intended to permit it to be connected to holders 12 so arranged as to engage around both the assembled channel structure 3 and a support 13, for example in the form of a tube, a post or a beam of some other kind. The holder 12 can be executed in the form of a divided holder 12A, 12B, which engages closely around the structure 3 and the support 13 to either side of a clamping bolt 14.
One end 6A of the base 6 of the profile lengths may appropriately exhibit a base flange 15, which is so arranged as to constitute an extension of the closely-fitting connecting flange 5 on
