Definitions

  • the invention relates to a folding table according to the preamble of claim 1.
  • So-called wallpapering tables are well known. she usually consist of two table top elements or - halves that are around a central cross to the table's longitudinal direction running tilt axis can be folded. This Tables have corresponding ones on the underside of the table Stand facilities and folding elements that can be folded up can be folded over to the underside of the table, around the so-called wallpapering table as a box-shaped element to be able to carry away.
  • a folding table comparable with the basic principle two collapsible table halves is from EP 0 064 365 B1 became known.
  • In the middle of the table is one foot device remaining even when folded provided with rollers.
  • the table halves are in a condition above tilting axis running transversely to the longitudinal direction of the table pivoted so that the tabletop halves are on of the stand equipment provided with casters. The In this way, the table can be put down and provided in the folded position become.
  • folding tables have also become known, a parallelogram arrangement on the underside of the table have, which as a guide and support device serves for the tabletop half.
  • a generic folding table is from US 3,861,325 A became known. It comprises two table top halves, which by means of a common the two tabletop halves centered in a fixed assignment to each other Joint axis are hinged together to the two tabletop halves from their horizontal Use position in a vertical standby position to be able to swivel in the table only a comparative narrow storage space required. To do this furthermore, the two table top halves are each on the outside pivotable about horizontal axes connected to the Legs are provided.
  • This table can also be used between a functional position, in which the two tabletop halves are in the usual way horizontal position, and a folded position can be adjusted in the two table top halves at least approximately parallel to each other lie.
  • the support leg devices due to the different kinematics the support leg devices compared to the normal use position additionally twisted.
  • a folding table is also from DE 198 47 397 A1 became known.
  • This includes two tabletop halves Folding table has a parallel to the table top level lever-shaped adjustment structure on the middle Side view of a trapezoidal area with the supporting device connecting the two tabletop halves includes.
  • the construction of this folding table is therefore further from the generic state of the art.
  • This folding mechanism according to the invention is constructed that the two tabletop halves only over the articulated support devices connected to each other are. To implement the required kinematics is also in complete contrast to the state the technology additionally provided that the two articulated Support devices a common connecting them Have pivot axis.
  • the table in A stand device is offset in the longitudinal direction of the table 1, which is more like the middle of the table outer front edge area is assigned.
  • the stand device 1 does not have to be exactly on the face area the table top 3 can be arranged, but can the front end of the table top 3 also further inside be provided.
  • each Pair of feet 1 ' in the embodiment shown from the underside of the table top to the bottom of the Stand device 1, mounted rollers 5 diverge, on the one hand in the direction of the opposite Longitudinal areas and the other in the longitudinal direction of the table.
  • the table top comprises 3 two table top elements 3 ', in the embodiment shown hereinafter also as table top halves 3 ' be designated.
  • each half of the table top assigned two each transverse to the table top longitudinal direction offset and in the longitudinal direction of the tabletop extending mounting rails 7 arranged, which u.a. also for additional support of the tabletop halves 3 ' serve.
  • the design includes several pivoting Tilting axes, all of them parallel and transverse to the longitudinal direction of the table top are arranged. Here are these pivot and tilt axes explained in detail below also aligned horizontally.
  • the stand device 1 is in each case via an upper one Stand tilt axis 15 at least indirectly articulated with the Underside of table top connected.
  • the stand tilt axis 15 is held over the mounting rails 7 and in this Embodiment thus indirectly with the table top halves 3 'connected.
  • this upper pedestal tilt axis 15 is at the Stand devices 1 have a lower stand tilt axis 17 trained or connected, on the one hand the respective support device 11, i.e. the respective double pipe device 11 'is supported in an articulated manner.
  • the two support devices 11 are over the middle one, which runs transverse to the longitudinal direction of the table Vertical / symmetry level 19 extended.
  • the longitudinal side view of the table intersect two mutually extending support devices 11 in the area of the middle vertical / symmetry plane 19, and on a cross to the longitudinal direction of the table in the middle Vertical / symmetry plane 19 horizontal Axis line 21.
  • a connecting axis 23 is along this axis line 21 formed the double pipe device 11 'of the two Supports 11 articulated together.
  • the associated stand device 1 opposite end of the respective support device 11 each have an articulated axis 27, via which the Support device 11 articulated with a spacer 29 which is rigid and rigid on the underside of the table the associated table top 3 'and / or on the mounting rails 7 is held and supported.
  • the construction explained has the following Special features on that the upper and lower pedestal tilt axis 15 and 17 not in a common transverse to Table top longitudinal direction vertical plane 31 lying, neither in the folded nor in the set up Status. Rather, it turns out that reference on Figure 1, the lower pedestal tilt axis 17 in the direction Table center is offset, the distance ⁇ the lower stand tilt axis 17 to one through the upper Pedestal tilt axis 15 extending horizontal plane 33 is preferred about 2 to 4 times the distance X between the lower stand tilt axis 17 and the through the upper pedestal tilt axis 15 extending vertical plane 31 corresponds.
  • the distance A corresponds to the respective one Joint axis 27 and the common connection axis 23 approximately the vertical distance B between the connecting axis 23 and the underside of the table top.
  • the distance A should be in the ratio B preferably between 30% to 300%, preferably 60% to 200%, in particular 90% to 120% vary.
  • a first coil spring is wound around the connecting shaft 23 37 and / or around the lower pedestal tilt axes 17 second coil spring devices 39 laid over what Biasing forces on the support 11 in the form of Double tube device 11 'act to collapse lighten in the direction of the illustration according to FIG.
  • the above-mentioned middle spring 37 is supported on both of them opposite spring ends (what in the drawings is not shown in detail) once on the in Figure 4 support device on the left or on the support device in FIG. 4 support device on the right, in the Closeness of the separation level 19.
  • the other external ones Spring devices 39 are on a connecting rod 40 attached, each horizontally on the two faces extending the connection or pedestal tilt axis 15 forms.
  • One end of this spring device is supported 39 each on the associated stand device 1 and the other end on a cross brace 8, which is different to the embodiment of Figure 4 usually is closer to the spring device 39, and the in Connects longitudinally extending mounting rails 7.
  • the two tabletop halves are in the ready position 3 'preferably adjacent to the middle vertical / Symmetry level 19 taken and the table tops after raised above.
  • the support devices 11 are with pivoted in the raised position, the outer Stand devices on their rollers 5 towards each other roll, as in an intermediate position according to FIG. 2 can be seen.
  • the two table halves can continue towards each other, the common Connection axis 23 moves upwards and the two Stand devices are moved towards each other.
  • the exemplary embodiment explained can be doubled in this respect or tripled, for example, by another, basically the same Folding table is provided as an extended table by for example a next interacting one Pair of table halves on an exceptional end face with the in Figure 4 left end hinged is. In the collapsed state there is then one double coherent construction according to the Representation according to FIG. 3.
