DISPLAY RACK

Abstract: A display rack consists of flat pane (2, 2') display frames (1, 1') to be interconnected by coupling members (6, 15, 16, 61-64, 72-74). The frames comprise corner pieces (5) and side frame members (3, 4) of extruded profiled tubes with two parallel tube portions (48, 49) and two longitudinal grooves (23, 30) in the plane of the display frame. The corner pieces have at least two pairs of parallel legs (39, 39'; 40, 40') to be inserted and adopted by said tube portions. Of the longitudinal grooves (23, 30) at least one externally located groove (23) of each display frame has an extrovert opening (22) narrower than the rest of the groove to prevent a spigot member (8, 161-164, 641-642, 741-744) introduced into the groove (23) from becoming taken out transversely. The corner pieces have cavities (45) in the extension of the recessed grooves (23) to permit the spigot members to be passed through the corner piece and into said recessed groove. Each coupling member has at least two spigots each of which is adapted for introduction through one of the cavities (45) of a corner piece and further into the corresponding recessed groove in a frame side (3, 4) for interconnecting two or more adjacent display frames at nearby corners.

Description: DISPLAY RACK The present invention concerns a display rack, which is built up from frames which enclose disks or plates, on which advertising and other information, prizes or the like can be shown, for example in shops, department stores and in exhibitions. The frames in such display racks are built up from, or composed of ; side wall pieces having the shape of extruded profiles consisting of two hollow--beam or tubular portions which are interconnected by means of a bridge portion, said portions then between themselves formi two longitudinally extending grooves in the side pieces mainly in the plane of the assembled frame. In such frames which the invention relates to, the lateral pieces of the frames are held together by corner pieces which are shaped with mutually rectangular pairs of legs or projections whic can be inserted into said hollow beam or tubular portio of the side pieces. Previously known frames are interconnected to larger racks or shields by means of fittings or couplings which are secured by screwing, or by menas of other fixing means attached to the frames. This is often effected in a manner costly and complicated for this purpose. It has now been found that an advantageous and amazin simple and cheap method can result in a display rack which is highly flexible and has low weight, by developing the construction described in the international printed public tion WO 84/04366 (patent application PCT/SE84/00087) . This is accomplished, according to the invention, thereby that o the mentioned longitudinal grooves at least one ^xternicall located groove of each display frame is shaped recessed, i. that the extrovert opening of the groove is narrower than the rest of the groove in order to prevent a spigot member introduced into the groove from being taken out from the groove transversely to the longitudinal direction thereof, that the corner pieces are formed with cavities in extension of the recessed grooves of the side member of the frames so as to permit the spigot members to be passed without any obstacle through the corner piece and 5 into said recessed groove, and that each coupling member comprises at least two spigot members, each of which is adapted for introduction through one of the cavi¬ ties of a corner piece and further into a corresponding recessed groove in a side member of the frame for the purp 10 of interconnecting two or more adjacent display frames at nearby situated corners. In another embodiment of the invention one or more spigots of a coupling member have one or more nibs, whi project through the opening of the recessed groove for the 15 purpose of preventing the spigot member from becoming ro¬ tated about its longitudinal direction relatively to the groove. In a third embodiment the spigot has a cross portion ψ shaped so as to force said cross portion to project so far 20 outside the spigot that the cross portion cannot be intror duced into the cavity in the corner piece in order thus to limit the distance over which the spigot can be inserted through the corner piece and into the recessed groove of the frame piece. 25 In a fourth embodiment the cross portion is constitut by a ball applied to the spigot. In a fifth embodiment the spigot is connected with a transversal sheet or disk shaped as a foot for the purpose of supporting the display frame in upright position at som 30 distance from the base. In a sixth embodiment the coupling member consists of two spigots arranged in alignment to each other for the purpose of interconnecting two display frames located, for example, the one above the other. 35 In a seventh embodiment the coupling member is shaped as a U with two mutually parallel spigots for the purpose of interconnecting display frames located side by side. In an eighth embodiment the coupling member has four spigot members interconnected in the form of an H for the purpose of interconnecting four display frames at adjacent corners of the frames in both lateral and vertical directions. In a ninth embodiment the spigot member is dimensioned such that it can be introduced through the cavity of the corner piece and into the longitudinal recessed groove of the frame side but by overcoming a frictional resistance. In a tenth embodiment the coupling member comprises two spigots arranged in alignment with one another and a tongue projecting roughly from the middle portion of the coupling member and perpendicularly from the spigots so as when interconnecting two display frames, positioned for example above each other, the spigots are received by the recessed grooves of the frame pieces, whereas the tongue is received in the two cavities of the adjacent corner pieces. In an eleventh embodiment the coupling member is composed of two, three or four coupling units , of which every one consists of two aligned spigots and one tongue vertically projecting therefrom, which tongues are inter¬ connected at their edges turned away from the spigots in such a manner that the tongues around their connection point are disposed with equally great angles between them, which means 180O. 120° or 90°, respectively, all spigots being situated in mutually parallel relationship. In a twelfth embodiment the coupling member is composed of two, three or four T-shaped coupling units, each of which is formed of a stalk or stem portion in the shape of a spigot and a cross portion fixed to the end of each £tem portion, which cross portions are interconnected at their one end in a common connection point in such a manner that the cross portions are disposed around their connection point with equally great angles between them, which means 180°, 120° or 90°, respectively, all spigots being situated in mutually parallel relationship. The invention shall be described nearer with reference to the attached drawings, of which Fig. 1 shows a display rack with two frames located side by side. Figs. 2 and 3 show those coupling members which are used in the display rack of Fig. 1, Fig. 4 shows a display rack with two lower larger frame and two upper minor frames, Fig. 5 shows a display rack built up from four equal frames, Figs. 6 and 7 show coupling members used in the display racks of the Figs. 4 and 5, Fig. 8 shows on a larger scale the lower coupling membe in the rack of Fig. 5 and adjacent frame corners.

Figs. 25 and 26 show in the same manner as Figs. 23 and 24 a threefold, single-sided coupling member, Figs. 27 and 28 show in a corresponding manner a fourfold, single-sided coupling member. Fig. 29 shows in a perspective view the adjacent and interconnected corners of six display frames. Fig. 30 shows in a corresponding manner as Fig. 29 eight interconnected display frames, whereas Figs. 31 and 32 show in perspective views three or, respectively, four interconnected display frames. In the Fig. 1 the reference numerals 1 and l' denote two equal display frames, each of which is composed of two horizontal side pieces 4, two vertical side pieces 3, four corner pieces 5 and a pane 2. Through hollow-beam or tubular formations in the side pieces and cavities in the corner pieces elongated bar-shaped parts, coupling spigots, can be introduced. In Fig. 1, L-shaped legs 7 are introduced into the outer lower corners, while the adjacent located side pieces 3 are interconnected by ϋ-shaped coupling members 6, as is shown nearer in Fig. 2. In Fig. 2 the reference numerals 8, 8' denote two legs in the shape of coupling spigots for the coupling member 6. Reference numeral 9 denotes a hook, which connects the legs 8 and 8 with one another, and reference numerals 10 denote balls threaded onto the legs and constituting stops against the corner pieces 5 under the insertion of the spigot shaped parts through a corner piece and into a side piece. In Fig. 2 the left-hand leg is provided with two nibs 11, the function of which will be declared nearer more below. Fig. 3 shows the L-shaped leg 7 with a spigot member 13, which has two nibs 11. Reference numeral 10 denotes a ball as before, whereas reference numeral 14 denotes a foot on the L-shaped leg. The display rack shown in Fig. 1 can be placed onto a support, against which the members 6 and 7 bear, and the rack can be set up steadily by the display frames 1, 1 forming an angle with each other. It is also possible to 5 ' turn the two display frames so that they become situated closely adjacent each other and then can easily be transport and mounted. In Fig. 4 reference numerals 17, 17' denote two pieces of. upper display frames and 18, 18 two pieces of lower dis- 10.: Flay frames which in that area where their earners meet, ar connected with an H-shaped coupling member 16. At the top in the centre the upper display frames are connected with a U- shaped. coupling member 6. At the outer edges of the display rack: the display frames are interconnected by means of strai 15 coupling members 15, the spigot members of which are intro¬ duced through the corner pieces and into the side pieces. Fig. 5 shows a display rack consisting of four equal display frames, two pieces of upper display frames 19, 19 and two pieces of lower display frames 20, 2θ'. The display 20 frames are connected with each other in the manner described above and the denotations are the same which have been used earlier. Fig. 6 shows the H-shaped coupling member 16, which can be said to consist of two U-shaped coupling members 6, the 25 " hooks 9 are connected with each other. Reference numerals 16* j _, lβ.,, I63 and I64 denote the four mutually parallel spigots. Fig. 7 shows the straight coupling member 15 with* wo out wards directed spigots 21, 2l', two balls 10, 10"' and a 30- flattened, portion 15' in the crntre of the coupling member. In. this embodiment the spigot members 21, 21 do not have any nibs. Obviously, it is possible also to constructthe abo described U- and H-shaped coupling members with spigots with out any nibs. SUBSTITUTE SHEET Fig. 8 shows on a larger scale the connection of the interior corners of the lower display frames 20, 20* in Fig. 5 by means of a U-shaped coupling member. Previously used reference numerals denote the same details as earlier. 23 denotes recessed grooves in the side pieces 3, 3 , whereas 24 denotes groove tongues which will be described nearer with reference to Fig. 9. Fig. 9 is a section following line IX-IX in Fig. 8. The figure shows a spigot-shaped coupling member 8 together with a nib 11 which projects between the two, each other directed grooves tongues 24, against which the nib 11 is slightly forced so as to prevent the spigot part 8 from rotating in the recessed groove 23. 25 denotes lateral walls in the groove 23, whereas 26 denotes the bottom wall of the groove. The spigot-shaped coupling member 8 is introduced into the recessed groove 23 in the longitudinal direction of the side piece through openings in the corner piece in a ma_J_vsr to be described later. It is obvious that if the spigot shaped part 8 introduced into the recessed groove 23 does not have any nibs, but is totally circular, the spigot part 8 can be rotated in the groove 23. Positioned opposite to the groove 23 in the side piece is a further groove 30 with lateral walls 29 and a bottom 28. In the shown embodiment this groove is of uniform width and designed to receive a pane 2. It is evident from the preceding description that the left-hand spigot member 8 in Fig. 8 due to the nibs 11 cannot rotate relatively to the side piece 3 in the groove 23 unless the U-shaped coupling member 6 is positioned in level with the left-hand display frame 20. Since the right-hand spigot member 8 of the U-shaped member 6 does not have any nibs, the right-hand display frame 20' can be swung about the spigot member 8 , so that the two display frames 20 and 20' can be set into an angular position in relation to one another. It is obvious that if the left-hand spigot member 8 in Fig. 8 is also without nibs, both display frames can be turned about their spigot members. This permits to swing the display frames flatly on top of each other and to be piled to¬ gether for more comfortable handling and transportation. Shown in Fig. 10 is a superstructure added to the dis- 5 play rack of Fig. 4. Here, the upper U-shaped coupling member 6 has been replaced by an H-shaped coupling member 16 Attached to the upwards directed spigot members are arms 31 equipped with lamps. In this way an easy expedient is obtain for providing lighting of the panes comprised in the display 0- rack.- E3_g-_.11 shows a development of the display rack shown in Fig..5 " , where the lower members 6 and 12 of Fig. 5 have been exchanged for three pieces of display feet, each of whi has a circular foot plate 35 and an upright 34. Each of the 5 outer uprights has a simple spigot member 15, whereas the intermediate upright has been connected with a U-shaped coupling member 6. In this way the entire display rack can pe placed at a desired height over the support. Fig.12 shows a similar constructionwhere the circular 20 foot plates 35 have been replaced by elongated flat irons 38 36J denotes feet having a single spigot member 15, whereas 37 denotes- a foot support with two spigot members interconnecte in the shape of a U. Fig. 13. is a perspective view of a corner piece 5 with 25.. two pairs of legs 39, 39' and 40, 40* extending perpendicula to each other and a connection portion 41, 42 between the leg pairs 39-40 and 39'-40*. 43 denotes a nipple fixin the connection parts 41 and 42 with one another. 44 denotes a spigot member on any of the earlier described coupling 30 members which passes through a cavity 45 in the corner piece 5 and is received within the recessed groove 23 in the side piece 4. Fig. 14 is a view in the direction of the arrow XIV in Fig. 13. Evident from the figure are the two connection par 35 41, 42, the connection nippel 43 as well as the cavity 45 i the corner piece through which the spigot member 44 can pass in order to be inserted into the recessed groove 23 in the side piece 4. From the Fig. 13 there becomes evident also the shape of the side piece 4 corresponding to that shown in Fig. 9. In the figure, reference numeral 23 denotes the recessed ■-» groove for taking up the spigot member 44 of a coupling member, whereas 46 denotes a groove for a pane 2. The groove presents at its opening two groove tongues 47, the spacing between them being adjusted to the thickness of the pane 2 belonging to the display frame. The groove 46 has also been made deeper than has been described before in order to ensur a safer grasp of the edge of the pane which is valuable especially when the frame pieces become vastly long and easily liable to be bent out. Fig. 15 shows a single, double-sided coupling member 61 with two spigot members 60 and 60 , which are located in lin with each other. Projecting perpendicularly from the centre of the coupling member is a tongue 59 which has an edge 59' directed away from the spigots. Fig. 16 shows the member viewed from above in Fig. 15. The denominations are the same in the Figs. 15 and 16. The coupling member shown in the Fig 15 and 16 may be used instead of the right-hand coupling member 15 shown in Fig. 4, the spigots 60 and 60* then being inserted into the recessed groove in the upper display frame 17 or 17 * or the lower display frame 18, 18'. whereas the tongue 59 is received by the adjacent cavities 45 between th legs of the corner pieces 5 directed, according to Fig. 4, towards the centre of the display rack. Figs. 17 and 18 show a twofold, double-sided coupling member 62 with two tongues 62- j _ and 62 2 . The coupling member 62 can be imagined as composed of two coupling members 61 joined together at 62 . All spigots in the coupling member 62 are parallel with one another. Figs. 19 and 20 show in a corresponding manner a three¬ fold, double-sided coupling member 63 composed of three single members according to the Figs. 15 and 16, the tongues w hi c h re interconnected at the same place 63' in such a manner that a coupling member with six spigots distributed in pairs at the same distance from each 5 other is obtained. The tongues are taken up by the cavities 45 of the corner pieces 5 in the same manner as described in connection with the Figs. 15 and 16. Figs. 21 and 22 show a fourfold, double-sided coupling member 64 composed of four coupling members according to the 0 Figs.. 15 and 16 and having four tongues 64^, 64 2 , 64 3 and 64 which are joined together at the same point 64 , as is evi¬ dent from the Fig. 22. Fig. 29 shows a joining between the corners of three upper and: three lower display frames by means of the couplin 15 member 63 shown in the Figs. 19 and 20. Fig. 30 shows four upper and four lower display frames which are coupled together by means of the coupling member 6 shown in the Figs. 21 and 22. Fig. 23 shows a twofold, single-sided coupling member 7 20 composed of two T-shaped coupling units with stem portions Zγ and 72_ and cross portions 1,, Tl ' sa *^°- portions 72 , and- 72 2 constituting spigots for co-operation with a frame corner in a manner described earlier. Fig. 24 shows the coupling member of Fig. 23 in a top 25. view, with the same reference numerals used. Fig. 25 shows a threefold, single-sided coupling member 73, which consists of three pieces of T-shaped members with stems 73-^, 73 2 and 73 3 directed upwards in the figure and having each an appertaining cross portion 5-^, 75 2 and 75 3 3.0. respectively, which portions at their one end are inter¬ connected at the point 73 in such a manner that the cross portions are situated in the same plane, whereas the shafts 73]_-733, which constitute coupling spigots, are directed vertically upwards from said plane and are parallel 35 with one another. Fig. 26 shows the coupling member 73 of Fig. 25 in a top view. Figs. 27 and 28 show in a corresponding manner a four¬ fold, single-sided coupling member 74 consisting of four pieces of T-shaped members with stems 74- j _-74 4 and cross pieces denoted, respectively 76,-76 4 , which latter are interconnected at a point 74 , see Fig. 28. The cross pieces 76- j _-76 4 are lying in the same plane and the shafts l ^- -l ^ are parallel and form a right angle with said plane. Fig. 31 shows three display frames which are inter¬ connected by means of the coupling member shown in the Figs. 25 and 26, which is suited for e.g. display frames placed on a support such as a floor. Fig. 32 finally shows four display frames, which are placed on a support and inter- connected by such a member as shown in the Figs. 27 and 28. The invention can be modified by an expert in the art in various manners deviating from what has been described hereinbefore, but within the scope of the subsequent patent claims.
