Definitions

  • the present invention relates to a folding table and shelf.
  • Folding tables which can also be converted into a shelf by pulling them apart, are already known from the prior art.
  • plate elements are usually arranged to one another by means of parallelogram guides in such a way that they are always arranged parallel to one another, so that when the table or the device is pulled apart, the plates form a flat table top and when pushed together or contracted, the base plates are offset from one another so that they form several shelves.
  • Plug-in shelving systems are known, for example, from US 2011/0068071 A1 and US 9,936,825 B1.
  • a folding table and shelf with the features of claim 1. It is then provided that a folding table and shelf is provided with at least one base frame, with at least one hollow beam attached to the base frame, at least two base plates , which are pivotably articulated to the hollow beam, with a base plate alignment mechanism being accommodated in the interior of the hollow beam, by means of which the base plates are aligned parallel to one another.
  • the invention is based on the basic idea of accommodating the necessary mechanics, by means of which the floor panels are always aligned parallel to one another or in alignment, in the interior of a hollow beam so that it is no longer visible from the outside. The inclusion of the entire mechanics in a hollow beam also ensures that a potential risk of crushing can be excluded.
  • the corresponding mechanism is thus completely covered and encapsulated, since it is essentially completely encapsulated or received in the interior of the hollow beam. It is therefore not accessible from the outside in the assembled state, so that it is not possible to get into the mechanism itself, for example with your fingers.
  • the encapsulated arrangement of the mechanics within the hollow beam also provides a visually appealing solution. It is also achieved that the moving parts of the base plate alignment mechanism are less soiled, since they are correspondingly encapsulated by the hollow beam.
  • the base plate alignment mechanism is a parallelogram guide.
  • the parallelogram guide is arranged completely inside the hollow beam.
  • Parallelogram guides can already be arranged accordingly in a hollow beam, such as a rectangular tube, e.g. with dimensions of 40x80mm or the like. This achieves a compact design.
  • a parallelogram guide is also easy to implement.
  • the parallelogram guide has at least two parallel guide rods and guide attachments, the guide attachments being non-rotatably attached to the base plates and the guide rods being movably, in particular rotatable, attached to the guide attachments.
  • the floor panels continue with corresponding non-rotatable bolts or rods are provided on which the guide attachments are attached accordingly.
  • This construction of the base plate alignment mechanism can be constructed in a comparatively simple manner. It is also conceivable that such a mechanism is lubricant-free. This can be achieved in particular in that the guide attachments are designed, for example, as plastic attachments, while the linkage, consisting of the parallel guide rods, is made of metal.
  • the bolts by means of which the guide attachments are fastened to the base plates, can also be supported by lubricant-free bearings. It is conceivable, for example, to use Teflon bushings or the like here.
  • the base plate alignment mechanism has a gear with a timing chain, the gear further having gear wheels, with one gear wheel each being non-rotatably attached to a base plate and the timing chain being guided on the gear wheels and being in engagement with them.
  • This has the advantage of having an alternative solution. It is conceivable, for example, to use the timing chain to couple the position of the base plates to one another via the gear wheels so that they are always either aligned or parallel to one another.
  • the alignment of the two floor panels or the multiple floor panels is viewed as an arrangement parallel to one another. It can also be provided that several base plates are provided. In particular, three base plates can be provided. However, it is also conceivable that several base plates are provided. It was found in the prototype construction that five or more floor slabs can be realized without any problems.
  • the hollow beam is at least partially formed from a half-shell sheet metal and / or a U-shaped sheet metal or a square tube or a square tube sheet.
  • the use of such materials or such semi-finished products allows simple and inexpensive manufacture of the hollow beam.
  • An assembly is also made possible by here.
  • at least one locking mechanism is provided, by means of which the position of the base plates can be determined indirectly and / or directly.
  • This locking mechanism (s) can in particular be arranged in the area of the hollow beam.
  • the locking mechanism makes it possible to set a specific position of the floor panels and then to fix them accordingly with the locking mechanism.
  • the locking mechanism can have one or more locking options.
  • the locking mechanism can also have an adjusting element such as a crank, by means of which the hollow beam and the base plates can be adjusted or rotated in their position.
  • an adjusting element such as a crank
  • the crank has corresponding latching positions.
  • the crank enables latching at any angle of rotation, that is to say that any position of the hollow beam can be fixed.
  • a clamping brake can be provided, for example, which can be activated, for example, by a push button.
  • a so-called pull latch can also be used, i.e. a spring-loaded locking button that is easily pulled out of its guide to release the hollow beam, thereby releasing the locking.
  • the pull latch is released and the latching is thereby re-established.
  • the orientation of the base plates can be changed.
  • the floor panels can not only assume horizontal orientations, for example.
  • the base plates can be placed at an angle and at any angle. In this context, however, it is provided in particular that the base plates always remain aligned parallel to one another.
  • the base plates can only be rotated and fixed in one direction.
  • the inclination can be set between 0 ° and 90 °.
  • Preferred positions for the inclination can be, for example, 20 °, 30 ° or 45 °.
  • Corresponding markings or corresponding stop positions or corresponding locking positions can be provided for this.
  • the base plates can be designed to be exchangeable.
  • the base plates are releasably attached to the folding table and shelf. In particular, it can be provided that these can be released or inserted and fastened without tools.
  • base plate should also be understood to mean that it not only includes pure plate elements, but also baskets or bucket holders or the like.
  • the floor panels can be made of any suitable material or a plurality of materials, such as wood and / or metal. It is also conceivable that the baskets or bucket holders are made of wire or plastic or Plexiglas.
  • the folding table and shelf can be designed to be mobile. It is conceivable, for example, that four rollers are provided on the base frame of the folding table (s) and shelf, each in a bottom corner of the base frame.
  • the corners of the floor panels can each be designed freely, i.e. no guides or the like are articulated here. This enables better possible uses of the floor slabs (also called floors), since objects placed on the floor slabs can now easily protrude.
  • an information device can be provided on the base frame. This is preferably designed to be exchangeable and arranged in the frame or between two frame parts.
