Fig. 6 is a sectional view through the support elements shown in Fig. 1, as well as the front, rear and side beams of the seat.

Fig. 1 shows a schematic longitudinal sectional view of a bench 1 or a table according to the present invention. This has a conventional seat plate 2 , on the underside of which a front bar 3 and a rear bar 4 are mounted in the transverse direction in the region of the front end V and the rear end H. In a similar manner, as shown in FIGS. 4 and 5, a right and left side bar 5 , 6 are attached to the underside of the seat in the region of the right and left bench ends, respectively, in the longitudinal direction of the bench. All bars 3 , 4 , 5 , 6 have essentially one rectangular cross section.

As shown in Fig. 4, the front, rear and side beams 3 , 4 , 5 , 6 z. B. with means of several conventional screws 7 a, 7 b and dowels attached to the seat plate 2 . The front ends of the front beam 3 and the side beams 5, 6 are shown in FIG. 6 flush with each other (the same applies to the rear ends of the side beams 5, 6, and the rear end of the rear beam 4).

The bench 1 has, according to Fig. 1, a front support member 7, and a rear support member 8 on. Each support element 7 , 8 consists, as shown in FIG. 5, of a crossbeam 9 , 10 , at the right and left end of which a support leg 11 , 12 , 13 , 14 is fastened.

Referring back to FIG. 1, the rear support element 8 is pivotally attached to the rear beam 4 (ie — indirectly — on the seat plate 2 ) via a rear hinge 16 . In ent speaking manner, the front support member 7 is rotatably attached to the bench front beam 3 via a front hinge 15 . For this purpose, the lower end of the front and rear beams 3 , 4 is connected to the upper end of a first element 15 a of the respective hinge 15 , 16 , and the lower end of the respective cross beam 9 , 10 to the upper end of a second element 15 b of the respective hinge 15 , 16 .

As shown in FIG. 6, the hinges 15 , 16 extend essentially over the entire length of the front, rear, or transverse beams 3 , 4 , 9 , 10 .

Referring again to Fig. 1, the support elements 8 , 9 extend in their first, from the folded position from the underside of the seat plate 2 at a right angle downwards. A counterclockwise rotation (ie a rotation counter to the direction of rotation indicated by the arrow R in FIG. 1) of the front support element 7 is prevented by the stop of the front crossbar 9 on the front beam 3 . Correspondingly de way, namely by the stop of the rear crossbar 10 on the rear beam 4 , a rightward rotation (ie a rotation counter to the direction of rotation indicated by the arrow L in FIG. 1) of the rear support element 8 is prevented.

A clockwise rotation of the front support member 7 in the direction of arrow R (ie to maintain the front support member 7 in the above-mentioned vertical position) to ver stop is mounted a front locking device 17 at the lower front region of the seat plate. 2 Correspondingly, one at the lower, rear area of the seat plate 2 on the arranged rear locking device 18 serves to prevent a left rotation of the rear support element 8 in the direction of arrow L (ie to hold the rear support element 8 in the above-mentioned vertical position). The exact functioning of the Arretiereinrichtun conditions 17 , 18 is explained in detail below in connection with Fig. 3a.

If the front locking device 17 (or the rear locking device 18 ) is released, the front support element 7 (or the rear support element 8 ) can be pivoted toward the center of the bench, ie in the direction of the arrow R (or in the direction of the arrow L), until the front support element 7 (or the rear support element 8 ) reaches the folded position shown in FIG. 2. In this position, the support elements 7 , 8 are in Chen wesentli parallel to the underside of the seat plate 2nd An even further clockwise rotation in the direction of the direction of rotation of the front support element 7 indicated by the arrow R is prevented by the stop of its right or left support leg 11 , 12 on the corresponding right or left side bar 5 , 6 . In a corresponding manner, an even further left rotation of the rear support element 8 is prevented by the stop of its right or left support leg 13 , 14 on the corresponding right or left side bar 5 , 6 . In the exemplary embodiment described here, the seat 1 is designed such that, in the folded position, the lower end faces of the left and right side beams 5 , 6 are the end faces of the support legs 11 , 12 , 13 , which are at the top in the position shown in FIG. 2 . 14 almost touch.

In the position shown in Fig. 2, the support legs 11 , 12 , 13 , 14 snap into known, be at the lower, central region of the side bars 5 , 6 arranged Rasteinrich lines 19 , 20 . These prevent the front support element 7 (or the rear support element 8 ) from pivoting back, that is to say a left turn of the front support element 7 (or a right turn of the rear support element 8 ).

When the support elements 7 , 8 are in the folded position, the seat 1 can be easily transported. In addition, with the support element position folded in each case, a plurality of benches constructed in the same way as the bench seat 1 can be stacked on top of one another in a simple, space-saving manner.

If the locking devices 19 , 20 are released again, the support elements 7 , 8 can be pivoted ent against the direction of the arrows R or L back into the position shown in FIG. 1. If the locking devices 17 , 18 are then actuated again as shown below, the support elements 7 , 8 can be fixed in the unfolded position.

According to Fig. 3a, according to a first embodiment of the invention, each of the locking devices 17, 18 a locking element 23, which each in a tion Ausspa is arranged on the underside of the seat plate 2 21. The recesses 21 extend almost over the entire width of the seat plate, and have a substantially rectangular cross section.

The locking element has a bore 24 with a circular cross-section which passes through this in a substantially vertical direction and which has a first diameter d1 at the bottom and a second diameter d2 at the top. A screw 22 is guided through the bore 24 and is screwed into the seat plate 2 from below. The upper, annular end surface of the screw head 25 is supported against the inner step 26 formed by the different bore diameters from the locking element 23 , more precisely against the likewise ring-shaped, downwardly facing outer surface.

The upper diameter d2 of the bore 24 is selected to be significantly larger than the outer diameter of the shaft 27 of the screw 22 . As a result, the locking element 23 can - apart from being guided by the screw 22 - move upwards and downwards a little forwards and backwards (somewhat backwards in the position shown in FIG. 3a). As shown in Fig. 3a, the locking member 23 has a cross-sectional shape which corresponds to the rectangular cross-sectional shape of the recess 21 in wesentli Chen. However, the front, lower area of the articulation element 23 is provided with an inward step 28 , and the rear, lower edge of the locking element 23 is rounded off or beveled, especially towards the rear. The height h1 of the locking element 23 corresponds essentially to the depth of the recess 21 in the rear region. Due to the level 28 , the front locking element height h2 is smaller than the height h1 in the rear area.

In a further recess 29 , which adjoins the recess 21 but is less deep and likewise extends almost over the entire width of the seat plate, an essentially rectangular transverse plate 30 is arranged, which is also fastened to the seat plate 2 . The cross plate 30 extends rearward somewhat beyond the edge between the two recesses 21 , 29 so that the front end area of the locking element 23 with the upper surface of the protruding transverse plate part and corresponding parts of the inner wall of the recess 21 is engaged ,

The upper, rear edge of the crossbar 9 is rounded off, predominantly upwards, and the upper, front edge of the crossbar 9 is chamfered, predominantly towards the front. Around the screw 22 , a spring element 31 is arranged, which is supported on the lower inner wall of the recess 21 , and the upper side surface of the locking element 23 . The locking element 23 is thereby pressed down, ie into the position shown in Fig. 3a, in which the rear end of the locking element 23 comes into engagement with the beveled, front-top region of the crossbar 9 . By the stop of the crossbar 9 on the locking element 23 , the right rotation of the front support element 7 in the direction of the arrow R is prevented.

To release the locking device 17 , this is pressed - against the spring force of the spring element 31 - by a user of the seat 1 upwards (or in the direction of an arrow S backwards-upwards). The locking element 23 is then pivoted essentially about a pivot axis Q in the direction of an arrow T until it lies completely within the recess 21 . The lower side surface of the articulation element 23 then lies flat with the underside of the seat plate 2 .

Since the rear end of the locking element 23 is no longer in engagement with the beveled, front-lying area of the crossbar 9 , the Stützele element 7 in the direction of arrow R around a pivot axis S to the position shown in Fig. 2 ge be pivoted. Lets the user of the bench seat 1 release the Arretierele element 23 , this is pressed again by the spring force to the position shown in FIG. 3a. As shown in Fig. 3a, the pivot axis S is spaced from the seat plate 2 or from the locking element 23 by more than 3 cm, in particular more than 5, 7 or 9 cm.

During the mounting of the support element 7 (ie the pivoting of the support element 7 from the position shown in FIG. 2 to the position shown in FIG. 1), the locking element 23 is pressed backwards-upwards by the crossbar 9 , so that it again in the direction of the arrow T is pivoted. If the support element 7 reaches the position shown in FIG. 3a, the locking element 23 is then pushed past the crossbar 9 by the spring element 31 back down, so that the support element 7 , as described above, is locked in the folded-in position.

In Fig. 3b, a detailed longitudinal sectional view of a locking device 17 'ge according to a second embodiment of the invention is shown. This is constructed in the same way as the locking device 17 shown in FIG. 3a. However, their - also arranged in a recess 21 'on the underside of the seat plate 2 - Arre tierelement 23 ' no bore, and no screw passed through this. The lower end of a spring element 31 'is on the upper side surface of the locking element 23 ', and the upper end of the spring element 31 'is fixed on the lower inner wall of the recess 21 ', so that the locking element 23 'downwards (or forwards) -down) is pressed.

A substantially rectangular cross-plate 30 ', which is fastened to the seat plate 2 , is arranged in a further recess 29 ', which adjoins the recess 21 'but is less deep and extends almost like the recess 21 ' over the entire width of the seat plate , The cross plate 30 'extends to the rear somewhat beyond the edge between the two recesses 21 ', 29 '. From the rear end of the cross plate 30 ', a shoulder 32 ' with a rectangular cross section extends upwards into a corresponding recess 33 'from the locking element 23 '. The extension 32 ′ extends almost over the entire width of the seat plate 2 . The recess 33 'is trapezoidal in cross section, so that the locking element 23 ' - z. B. in that a pressure against the locking element 23 'is exerted by a user of the seat 1 from below or below-front, about a pivot axis Q in the direction of an arrow T, until it is completely inside the recess 21 ' lies.

Since then the rear end of the locking element 23 'is no longer in engagement with the beveled, front-top region of the crossbeam 9 , the Stützele element 7 in the direction of arrow R around a pivot axis S around in Fig. 2 ge showed position to be pivoted. Lets the user of the seat 1 the Arretierele element 23 'go, this is pressed again by the spring force to the position shown in Fig. 3b development. As shown in Fig. 3b, the pivot axis S is from the seat plate 2 or from the locking element 23 by more than 3 cm, in particular more than 5, 7 or 9 cm apart.

During the folding in of the support element 7 (ie the pivoting of the support element 7 from the position shown in FIG. 2 to the position shown in FIG. 1), the locking element 23 'is pressed backwards-upwards by the crossbar 9 , so that it again in the direction of the arrow T is pivoted. If the support element 7 reaches the position shown in FIG. 3b, the locking element 23 'is then pushed down past the crossbeam 9 by the spring element 31 ', so that the support element 7 is locked in the folded position.

In Fig. 3c is a detailed longitudinal sectional view of a locking device 17 "is shown according to a third embodiment of the Invention This is according to how the locking device 17 shown in Figure 3a constructed However, includes the -...
