Description: FRAME AND SUSPENSION DEVICE PRIMARILY FOR SO-CALLED AV-SYSTEMS. The present invention relates to a frame construction primarily for so-called audiovisual systems and in¬ tended to be hung preferably on a carrier device and comprising, for instance, presentation devices, such as presentation boards, screens and the like forming part of said systems, said frame construction compris- ing mutually connected side-parts. The invention also relates to a suspension fitting. Arrangements for audiovisual systems are known to the art. The known technique, however, is encumbered with serious drawbacks. For instance, the presentation boards, etc., are hung at a considerable distance from the supporting walls or the like of known systems. Furthermore, the boards, etc., are expensive due to their complicated construction. The known systems are also relatively inflexible and do not enable the boards, etc. , to be turned. The present invention relates to arrangements in such systems which solve the problems associated with known arrangements. The invention thus relates to a frame construction according to the following Claim 1 which is mainly characterized by the features set forth in the charac¬ terizing clause of said Claim. The invention also relates to a suspension fitting according to the following Claim 6. The invention will now be described in more detail with reference to exemplifying embodiments thereof and also with reference to the accompanying drawings, in which Fig. 1 is a vertical sectional view of a first embodiment of an inventive presentation or display device, and shows a joint part and a suspension fitting among other things; - Fig. 2 is a front view of a presentation device according to Fig. 1; - Figs. 3a and b illustrate a joint part according to Fig. 1, and Figs. 3c-f illustrate corner fittings; - Fig. 4 illustrates an inventive suspension fitting; - Figs. 5a and b illustrate a runner-carrying axle part of the fitting shown in Fig. 4; Figs. 6a-d illustrate half of a fitting attachment part for the fitting shown in Fig. 4; Figs. 7 and 8 are cross-sectional views of a double and a single transverse strip respectively, said strips functioning primarily to support presenta¬ tion or display devices in accordance with the invention; and - Fig. 9 is a cross-sectional view of a profiled section according to the invention. Fig. 1 illustrates a frame construction 1 which is intended primarily for so-called audiovisual systems intended preferably to be hung from wall-mounted support devices 2, Figs. 7 and 8, such as a supportive strip, and to be comprised of presentation or display devices 3, such as presentation boards, screens and the like included in the system. The frame construc¬ tion includes frame parts 4 which are joined together in pairs and which are comprised essentially of pro¬ filed sections 4 which are intended to be joined together in pairs in the vicinity of corners 3 by means of a joint part 6 which includes two attachment parts 7, each being intended to be fastened in a respective profiled section, and an intermediate spacer part 8 which forms a predetermined angle, such as an angle of 90° between the attachment part and extends between the profiled sections. The spacer part is intended to be covered by or essen¬ tially covered by a corner fitting 9 which has gener¬ ally the same external cross-sectional profile as the profiled sections, Fig. 2 and Figs. 3c-f, so as to obtain a smooth and attractive corner section. The attachment parts 7 are guided in respective profiled sections and are fastened in the profiled sections with the aid of at least one attachment element 10 by means of a snap-fastener construction. The attachment parts are preferably resiliently arranged and include at those parts 12 thereof which lie proximal to the inside 11 of the frame construction at least one fastener lug 10 which is intended for snap-in engage¬ ment with a hole 13 provided in the inner surface 14 of a profiled section. The spacer part 8 preferably includes a supportive part 8' which faces towards the inside of the frame construction and which extends at an angle of about 45 ° to the longitudinal axes of the frame parts form¬ ing the corner. The reference numeral 15 identifies generally a sus¬ pension fitting by means of which presentation devices 3 are intended to be hung from carrier devices 2, preferably in the form of carrier strips 2, wherein the fitting includes at least one runner 16 which supports respective presentation devices in rolling contact with the carrier devices. The fitting 15 includes a fastener part 17 which is intended to be fitted into a frame section 4 of the presentation device 3, and a runner-carrying axle part 18 and a runner axle 16' and is rotatably connected to the fastener part. The axle part is preferably rotatable through 360 * in relation to the fastener part. According to the illus¬ trated embodiment, the runner axle extends essentially at right angles to the axle part, wherein the carrier strip or like device is intended to extend generally horizontally. As shown in Fig. 5, the axle part includes a circu - ferentially extending flange element 19 which is intended to coact with internal grooves 20 in the fastener part, Fig. 6, so as to provide a rotatable connection between the axle part and the fastener part. According to one preferred embodiment, the fastener part includes two halves 21 which are intended to embrace the axle part. The fastener part includes two mutually opposing attachment shoulders 22 which are intended to coact with two mutually opposing holes 23 in a frame section into which the fastener part is intended to be inserted, as illustrated in Fig. 1. Each attachment shoulder is resiliently mounted by means of a respective resilient tongue 24 and are intended to be moved towards one another against the action of a spring force when introduced into the frame section and to snap into the holes 23. The halves 21 are guided in relation to one another and are joined together by means of pins 21'. The double carrier strip 2 includes two tracks 2 ' and the single carrier strip 2 includes one track 2 ' in which runners 16 are intended to move when a presenta¬ tion device or the like fitted with a frame construc- tion hangs from the strip. The double strip can sup¬ port two frames, an outer frame and an inner frame, from a wall or the like on which the strip is mounted. The function of the arrangements according to the invention will be understood in all essentials from the aforegoing. The invention affords considerable advantages over earlier known techniques. For instance, the frame construction is simple and stable and can be readily assembled and because of its flexibility enables large variations to be made. The suspension fitting is highly functional and is simple and inexpensive to produce. Both the joint part and the fitting can be conveniently manufactured from a plastic material. The invention has been described above with reference to exemplifying embodiments thereof. It will be understood, however, that other embodiments and minor modifications and supplementations are conceivable without departing from the concept of the invention. According to one embodiment, the fastener part 17 of the suspension fitting 15 includes a fastener part 25 which includes a peg 26 or the like for fastening the fitting to a frame part, where the fastener part 25 extends out from the upper part of the fastener part. It is also preferred to provide the outer side 27 of the spacer part of the joint part with a central guide ridge 28 for guiding coaction with a corresponding internal recess or aperture 29 in the corner fitting 9, and to provide the corner fitting with an internal peg or pin 30 or the like arranged for snap-fastening coaction with a corresponding recess or aperture 31 in the spacer part 8, or vice versa, for fastening the corner fitting. In many instances, it is preferred that the lower part 32 of the frame construction, Fig. 2, will include support rollers 33 which determine the distance from a wall or like structure and which facilitate movement of the display device or the like. The presentation or display devices concerned are mounted in or on inventive frame constructions. In this case, the profiled elements 4, the frame sections 4, Fig. 9, include two mutually opposing wall parts 34 which define therebetween a U-shaped recess for the attachment of boards, etc. The suspension fitting may also be used for many different types of elements, such as shelves, lighting, etc. According to one preferred embodiment, the two free ends 7' of the attachment part 7 have a tongue-like configuration with a more slender cross-sectional area than the more central, supportive parts of the attach¬ ment part 7, so as to possess suitable resiliency for said snap-fastener construction, wherein said free ends support said fastener element 10, and wherein said free ends are intended to be bent outwardly from respective walls of profiled sections that lie proxi¬ mal to said fastener element against a spring force. The corner fittings 9 will preferably be adapted to the profiled sections with regard to colour and sur¬ face structure, and the attachment parts 7, which are intended to be covered by the corner fittings, can be given a standard design irrespective of the colour, etc., of the frame construction. The invention is thus not restricted to the aforedes- cribed and illustrated exemplifying embodiments there¬ of and modifications and changes can be made within the scope of the following Claims.
