embodiments

The detailed description is given below with reference to the attached drawings an embodiment of the inventive Table.

For the entire further description the following definition applies: Are in one Figure for the purpose of graphical uniqueness included reference numerals, but in the directly related description text is not explained, it is on their mention in previous or following description of the figures taken. For the sake of clarity, reference is made to the repeated designation Of components in other figures mostly omitted, if drawing It is clearly recognizable that these are "recurring" components.

FIG. 1

The table shown consists of a table top 1 , which may have round or other geometries and resting on four feet 2 resting on the floor. To achieve the stackability of the table, the vertical sections 22 of the feet 2 extended outside the area overshadowed by the table top 1 .

FIGS. 2A and 2B

In the view under the table top 1 , the underlying bracket is visible. A base part 3 is fixed centrally on the underside 10 of the table top 1 , preferably screwed. Symmetrically distributed on the bottom 10 of the table top 1, near the outer edge 11, four two-piece couplings 4 are arranged. Each clutch 4 consists of a primary coupling part 5 and a secondary coupling part 6. The primary coupling parts 5 are also attached to the underside 10 of the table top 1 , preferably in turn screwed. In each case, a secondary coupling part 6, however, is attached to each foot 2 , on the upper side of the running under the table top 1 horizontal portion 21. Preferably, the fastening is done in turn by means of screws.

The four existing feet 2 extend from the periphery of the base part 3 as horizontal sections 21 beyond the outer edge 11 , where they are bent at right angles into vertical sections 22 , which sit with their lower ends 23 at the bottom. Usually, a slider 24 is used here. In the base part 3 facing plug-in ends 20 of the feet 2 sitting pin 7, which are intended for docking to the base part 3 . In the fully assembled state, the secondary and primary coupling parts engage in each other 6.5 , the secondary coupling parts 6 are the primary coupling parts 5 set in the direction of the base part 3 , and all four plug pins 7 are docked to the base part 3 . The plug-in pin 7 initially have a shaft portion 70 which is provided with a surface profiling 71 , is provided for insertion into the open plug-in ends 20 of the existing feet 2 feet. Furthermore, the plug-in pin 7 has a protruding from the mating ends 20 head portion 72 , which serves to dock to the base part 3 .

FIGS. 3A and 3B

The base part 3 is, in principle, a flat-cylindrical body which, in accordance with the four docking ends 20 of the four feet 2 to be docked , also has four cavities 30 which are cross-shaped and aligned with the tapered plug ends 20 . At the top, the cavities 30 are initially completely open, but the top side of the base part 3 is covered by the table top 1 after assembly. The periphery of each cavity 30 is partially closed by an outer wall 31 , which, however, has a radial recess 32 and a recess 33 located on the upper side of the base part 3 . The recess 33 is wedge-shaped and narrows in the direction of the center of the base part 3. Through the base part 3 , four screw holes 34 extend for attachment to the table top 1. In each cavity 30 is a coil spring 35 which is biased against the outer wall 31 is supported ,

The head part 72 of each seated in the mating ends 20 of the feet 2 plug 7 consists of a his shaft portion 70 perpendicular final base plate 73, which projects beyond the top of the shaft portion 70 . At the top of the base plate 73 extends a horizontal angled tongue 74 against the axial extent of the shaft portion 70. On the side of the V-tongue 74 , a vertical center web 75 T-shaped on the base plate 73 is placed. The central web 75 sets from below to the V-shaped tongue 74 T-shaped and ends at the bottom with the base plate 73. In the docked state, the V-tongue 74 comes to rest in the wedge-shaped recess 33 and the vertical center bar 75 is retracted into the radial recess 32 . At the same time press the leading edges of the central web 75 and the V-tongue 74, the lying in the cavity 30 coil spring 35 together. The base part 3 and the plug-in pin 7 can be advantageously produced by plastic injection molding.

FIGS. 3A and 3C

The coupling 4 composed of the primary and the secondary coupling part 5 , 6 also produces, in principle, a flat-cylindrical body. The intended for attachment to the underside 10 of the table top 1 primary coupling part 5 is of crescent shape, ie the secondary coupling part 6 facing peripheral contact surface 50 is concave, parabolic cut out. The intended for attachment to the top of the horizontal portion 21 of the foot 2 secondary coupling part 6 is of complementary lenticular shape, ie, the primary coupling part 5 facing peripheral contact surface 60 is convex, bulged like a parabola. At the bottom of both coupling parts 5.6 is a groove 52,62 available to partially embed the cross section of the foot 2 , namely, when the secondary coupling part 6 is fixed to the foot 2 and when the foot 2 is docked to the base part 3 , So both coupling parts 5,6 are joined together and the horizontal portion 21 of the foot 2 is also in the primary coupling part 5 . At the concave contact surface 50 , a wedge contour 51 is present in each case in the outer region, which extends horizontally in the centric direction. The complementary contact surface 60 is provided with two grooves 61 , so that when the coupling 4 is assembled, the wedge contours 51 engage positively in the grooves 61 . For fastening, both coupling parts have 5.6 screw holes 53, 63.

FIGS. 4A to 4F

In the locked state, the head part 72 of the inserted in the insertion end 20 of the foot 2 pin 7 is docked to the base part 3 by the V-tongue 74 is retracted into the recess 33 and the central web 75 into the recess 32 . The coil spring 35 presses against the Veilzunge 74 and the central web 75 and thus pushes the foot with the attached secondary coupling part 6 on the attached to the table top 1 primary coupling part 5. On the side of the base part 3 thus arises between the recess 33 and the V-tongue 74, a gap S. in any case, however, remains the wedge tongue 74 in the recess 33 to rest on the outer wall 31 and the center web 75 in the recess 32 stuck, since the coil spring 35 inwardly of the outer wall abuts 31 and the base 2 can not eject.

On the side of the clutch 3 , the secondary coupling part 6 is pressed against the primary coupling part 5 by the pressure of the coil spring 35 . In this case, the contact surfaces 60,50 come close together, so that the wedge contours 51 engage with the grooves 61 . Thus, the inserted foot 2 is securely held under the table top 1 . At the base part 3 of the plug pin 7 and thus the mating end 20 of the foot 2 escape neither up nor down. Upwards, the tongue 74 pushes against the table top 1 and down the tongue 74 sits on the outer wall 31 . The secondary coupling part 6 can not be removed from the primary coupling part 5 of the clutch 4 with the attached foot second In the axial direction of the foot 2 , the coil spring 35 presses the coupling parts 5, 6 together and a vertical movement apart is impossible by the engagement between the wedge contours 51 with the grooves 61 . In the same way, the remaining three feet 2 are held between the base part 3 and the three associated couplings 4 .

FIGS. 5A to 5F

In the unlocked state permitting the insertion of the foot 2 or its dismantling of the table plate 1, the head portion is further inserted 72 of the spigot 7 of the foot 2 used in the plug end 20 in the base member. 3 The Veilzunge 74 penetrates deeper into the recess 33 and the central web 75 is further retracted into the groove 32 . To achieve this, one must push the foot 2 in the axial direction of the horizontal portion 21 against the pressure of the coil spring 35 in the direction of the base part 3 . The Veilzunge 74 and the central web 75 press the coil spring 35 axially together, ie away from the inner side of the outer wall 31. The gap S between the Veilzunge 74 and the recess 33 is reduced or completely closed. By the displacement of the foot 2, the secondary coupling part 6 moves away from the primary coupling part 5, so that the wedge contours 51 extend out of the grooves 61 . Thus, the foot 2 can first pivot away from the table top 1 in the region of the coupling 4 and then pull the tongue 74 out of the recess 33 .

In the reverse sequence, the insertion of the foot happens 2. First you have to insert the V-tongue 74 at an angled foot in the recess 33 and the contact surfaces 50,60 of the coupling parts 5,6 approach each other. With further insertion of the head part 72 of the plug pin 7 in the base part 3, against the pressure of the coil spring 35, the two coupling parts can bring 5.6 in a horizontal plane. If one no longer counteracts the coil spring 35 , the secondary coupling member 6 pushes against the attached to the bottom 11 of the table top 1 primary coupling part 5 and the wedge contours 51 jump into the grooves 61. In the same way let all four feet 2 mount or disassemble.

FIGS. 1B, 4E, 4F and 6

For stacking a plurality of tables cone-like stacking pins 8 are provided, which are respectively inserted from the accessible bottom in the secondary coupling part 6 . The stacking pin 8 has a groove 82 for embracing the cross section of the foot 2 and two latching hooks 84 . Complementary to the latching hook 84 has the secondary coupling part 6 in the region of the screw holes 63 engagement contours 64. for the detachable anchoring of the latching hook 84. The lower edges of all four stacks pin 8 inserted put on top of the table plate 1 of the stacked below table on. The stacking pins 8 cause both a stabilization of a number of stacked tables and the conservation of the tabletops. 1

FIGS. 7A to 7C

Compared to the previous figures - see in particular the similar figures 2B and 3B - is to prevent the unintentional release of a foot 2 of the clutch 4 and the base part 3, the holder now additionally equipped with a locking washer 300 . The locking washer 300 is fastened to the underside of the base part 3 by means of a centrally inserted fastening element 310, for example a screw, which projects into a central bore 36 in the base part 3 and engages therein into an internal thread 37 . For receiving the fastening element 310 , the base part 3 has on its outer circumference a downwardly pointing collar 38, which constitutes an elevation of the outer wall 31 and has constrictions 39 (see FIG. 8A) congruent to the recesses 32 .

The locking washer 300 has a central bore 301 for the passage of the fastening element 310 and four of the outer periphery of the locking washer 300 in the direction of the central bore 301 oriented indentations 302, which are offset from each other by 90 ° and thus, with a corresponding rotational position of the locking washer 300, congruent the pricks 32 come to rest. The fastening element 310 , which is preferably arranged in a manner secured against loss, can be tightened and loosened so that the securing disk 300 is fixed or can be rotated about the axis of rotation formed by the fastening element 310 . To tighten or loosen the fastener 310, in the head 311 an externally accessible engagement contour 312, for example, a simple transverse slot, available, so that no special tools is required, but for example with a coin adjustment of the fastener 310 can be done. When inserted, the locking washer 300 is surrounded by the collar 38 on the base part 3 , the head 311 of the fastening element 310 lies in the locking washer 300 in a seat 303, while the shaft 313 protrudes through the central bore 301 into the central bore 36 .

Figures 8A and 8B

This pair of figures illustrates how a plug pin 7 is inserted at a plug end 20 of a foot 2, in the base part 3 and is held by the lock washer 300 in the locked position. The recesses 302 of the locking washer 300 are rotated away from the recesses 32 , so that the outer periphery of the locking washer 300 prevents the front edge of the central web 75 of the spigot 7, which is inserted in the mating end 20 of the foot 2 , on further penetration into the groove 32 . Thus, the foot 2 is held in the locked position between the clutch 4 with the primary and secondary coupling half 5.6 on the one hand and on the other hand, the base part 3 . A loosening of the coupling halves 5,6, which would be possible only by deeper insertion of the pin 7 in the groove 32 on the base part 3 is blocked at this rotational position of the locking washer 300 . On the outer circumference of the locking washer 300 , two spaced-apart lugs 304 are provided, which enclose the central web 75 between them. This represents an additional safeguard of the blocked situation and signals the correct position of the locking washer 300 .

Figures 9A and 9B

On the other hand, if the locking washer 300 has been moved into a rotational position where its indentations 302 lie in the areas of the recesses 32 , then the respective recess 32 is open for a further insertion of the upcoming central web 75 . Only in this rotational position of the lock washer 300 , it is thus possible to insert the arranged on the foot 2 pin 7 as far as the groove 32 on the base part 3 against the coil spring 35 , that the coupling halves 5,6 out of engagement and the foot 2 of the table top. 1 can be removed.

FIGS. 10 to 11C

In the embodiment of stackable tables, the vertical sections 22 of the feet 2 directed towards the bottom project beyond the outer edge 11 of the table top 1. Thus, the vertical sections 22 of the legs 2 of tables piled higher up enclose the table tops 1 underneath tables. In this case, each table positioned further above must be rotated about the vertical axis in relation to the respective table positioned below it, at least about the cross section of the vertical sections 22 , so that the vertical sections 22 can fit next to one another. By keeping to the tightest rotation you can achieve the best order and highest stack density.

The undersides of the stacking pins 8, which are attached to the feet 2, in the region of the horizontal sections 21, gently set on the upper side 12 of the table top 1 of the respective table positioned below in the stack. Here, the couplings 4, the horizontal sections 21 of the feet 2 and the base part 3 are held with the attached plug-in pin 7 at a distance from the top 12 of the table top 1 of each underlying table.
