Definitions

  • the invention relates to a table which is foldable from a number of blanks, in particular corrugated cardboard, and which comprises a table top and this form-fitting and / or non-positively supporting supports.
  • Such a table made of corrugated cardboard blanks is used as a party and craft table in retail and use.
  • the table top is folded in a U-shape.
  • the web of the U forms the table surface, while the two shorter U-legs represent side surfaces, which are inserted into and held in cuboid boxes that serve as supports or legs. These boxes also serve as packaging and means of transport for the folded table.
  • the table surface is coated with a wax film.
  • the overall design of this table shows its "replacement" character extremely strongly.
  • the U-shaped table top does not have a particularly high load-bearing capacity.
  • the bending stiffness is only given in the context of the resistance of the corrugated board, supported by the U-legs, so that the supports must be relatively wide and must be arranged at narrow distances from one another over the table length.
  • the invention is based on the object of creating a table of the type described at the outset, which, with inexpensive production and thus also distribution costs, using a minimum of cuts, provides increased dimensional stability, in particular bending and torsional rigidity of the table top, while at the same time including the achievement of these has increased load-bearing capacity necessary technical measures in the design.
  • the table top consists of a substantially closed, vertically triangular folded profile hollow body, the hypotenuse determine the table surface and its catheter side surfaces and the means of folding tongues or flaps arranged on it, preferably against each other and with these locking elements to be brought into locking engagement, in particular in the form of end elements, is kept dimensionally stable.
  • the triangular, closed hollow profile body gives a table top that has the shape of a triangular isosceles prism with high bending and torsional rigidity.
  • this geometric shape it is possible to sit comfortably at the table from its longitudinal side walls, apart from the fact that this shape gives the table a special and peculiar shape. Due to the inclination of the side surfaces from the table surface downwards, the table top can be positively supported on it in a simple manner with appropriate design of the recesses provided for it, without necessarily having to use non-positive connection means.
  • the end face of the end elements substantially corresponds to the profile cross section of the table top and tabs are arranged along their edges, which preferably abut against the surfaces of the profile hollow body from the inside and slots for locking engagement with the folding tongues.
  • the table surface is cross-divided in its longitudinal or symmetry axis and the folding tongues extend essentially at right angles from the dividing edges into the interior of the hollow profile body.
  • This embodiment is particularly advantageous because it takes into account the fact that deviations from the planicity can easily occur with large-area corrugated cardboard due to external influences such as moisture; the larger the areas, the greater the deviation from the planicity.
  • the table surface is the largest surface on the object and is also the focus of attention, it is a major effort to give this surface all the prerequisites for ensuring optimal planicity, which is done by the transverse division in the longitudinal axis. The resulting from this division longitudinal seam still leads to a creative advantage because they ubendominante a pronounced L of the table surface is obtained. How through Experiments could be determined, with such a divided table surface there are practically no bulges.
  • the desired dimensions play an important role, - if the table surface is undivided and if the folding tongues are arranged along the opposing edges of the side surfaces and towards the table surface Extend interior of the hollow profile body. In this case, the table surface is not divided, but the division lies in the colliding lower edges of the two inclined side surfaces.
  • the folding tongues are advantageously designed as support tabs extending from their folding edge through the entire hollow profile body to the opposite inner surface or edge. This means that when the table surface is divided, the table surface parts against the "underside” i.e. support the connection area of the two side surfaces, while in the case of the undivided table surface bending of the table surface is also avoided, but it is easier on the latter to the bulges described above e.g. can come as a result of moisture.
  • the side surfaces of the hollow profile body can expediently enclose an obtuse angle. This results in particularly favorable conditions with regard to the use of the table from the long sides, since people sitting on the long sides can comfortably reach under the table top with their legs.
  • Such obtuse-angled configuration of the side or bottom surfaces of the table top also allows the particularly secure support on the supports in a favorable load distribution, in particular because of low generation of horizontal forces and exceeded as g vertical load end through the shallow angle of inclination.
  • the table top has a high level of bending and torsional rigidity and tables with up to 7 u and at least 2.5 m can be used if only two supports are used, without the fear of any loss of strength, it is in many cases prefiltering if the profile hollow body is in the longitudinal direction of the table at least two plate parts are divided, which are connected to one another in a positive and / or non-positive manner.
  • Such a northing on the one hand complies with the existing production possibilities of conventional corrugated cardboard production plants and, on the other hand, ensures that cuts of a reasonable size are available which also meet the dimensional limits prescribed for mailing.
  • connection of the table top parts to one another can take place in a particularly advantageous manner in such a way that the plate parts are twisted together by means of connecting elements which are inserted, for example pushed in, into the hollow profile body, in terms of their outer dimensions and their shape, essentially corresponding to the interior of the hollow body and also designed as hollow bodies. and are rigidly connected.
  • Such connecting elements thus fit perfectly into the basic idea of the invention to have a stable table set up practically exclusively from pre-folded blanks in a simple manner by the end user, since these connecting elements are also hollow bodies unfolded from blanks and can therefore be produced and delivered in a kit .
  • the connecting elements are adapted to the shape of the interior of the hollow profile body.
  • two connecting elements are required, each of which can be inserted into one half of the interior space which is divided by the support brackets and produce a positive connection between the two table top parts arranged in the longitudinal direction.
  • the opposing folding tongues or support tabs in the vicinity of their fold line mechanically with each other by stapling, gluing or the like. get connected. This can be done by the manufacturer of the blanks on a conventional system.
  • the interconnected folding tongues or support tabs can be folded flat inwards so that the wrap can be made available to the end user in such a way that he only needs it needs to erect and can quickly produce the finished profile body by inserting the connecting elements and the end elements.
  • the supports are preferably formed as a hollow body in the form of a rhombus in horizontal section, the lower edges of which form a standing plane and the upper edges of which define a cutout for the form-fitting mounting of the side or lower surfaces of the profile body.
  • This provides relatively simple supports that ensure extremely stable storage of the table top with an attractive design.
  • they can be provided on their upper edges with foldable contact tabs, with the aid of which the exact position of the cutout and thus the positive fit for the tabletop to be fitted can be determined.
  • the supports can also be designed as closed, foldable ring bodies which are mechanically connected in the region of the free edges of the support blank by means of a connecting tab, in particular by gluing or stapling. This means that the supports can be prepared by the manufacturer to such an extent that the end user only has a minimum of personal activity.
  • a particularly advantageous implementation possibility of the invention consists in that the blanks forming the table can be provided as a kit which can be dispatched.
  • the blanks for the table top or the plate parts and for the supports can be provided as pre-assembled, flat folded sleeve bodies, so that the end user can set up the table with little effort and have it available at short notice, while on the other hand when the table is not needed, it can be folded up and stored again in a space-saving manner.
  • the overall advantages that can be achieved with the invention are that an inexpensive table consisting of simple blanks made of foldable material, in particular corrugated cardboard, is provided, which is shipped from the manufacturer to the end user with minimal space requirements and is already prepared so far for final assembly it may be that the final erection can be carried out on site without special manual skills.
  • the geometric shapes of the table top and supports caused by the technical functions also result in a completely new, aesthetically particularly appealing design of a light and easy-to-use table with a high load-bearing capacity and resilience in relation to the material used.
  • this material can of course also be cardboard or other foldable material such as laminated cardboard or corrugated cardboard.
  • FIGS 1 to 3 show in different views a table 1 constructed according to the invention in a ready-to-use state.
  • This table 1 comprises as essential components a table top 2, which is provided as a triangular, wound profile hollow body 21, and two supports 3 also provided as wound hollow profiles.
  • the table top 2 determines a table surface 211, which is the hypothesis of the triangle of the profile hollow body 21 forms, as well as two of the table surface 211 inclined downward, butting side surfaces 212 which collide at an obtuse angle with Fig. 4, are explained in more detail.
  • the two supports 3 supporting the table top 2 are rhomboid-shaped and each define four supporting walls 31 with a horizontal lower edge 32, which ensure a safe stand-up on a level floor accomplishes.
  • the supports 3 have upper edges 31 which, in the unfolded state, form an angular cutout corresponding to the side surfaces 212, so that the table top 2 with its side surfaces 212 can be positively supported on the supports 3.
  • the embodiment variant of the table 1 according to the invention shown in FIG. 4 shows a table top 2 divided in the longitudinal direction into two plate parts 213 and 214, this representation in the front part, that is to say for the plate part 213, showing an unfolded state during assembly.
  • the erection process and the arrangement of the divided table top 2 of FIG. 4 are, however, in principle the same as for the undivided longitudinal table top of the embodiment according to FIGS. 1 to 3.
  • FIG. 5 shows a tabletop blank 20 for an undivided tabletop (FIGS. 1 to 3) or 2130/2140 for a divided tabletop (FIG. 4).
  • the only difference is that the length of the cut for the undivided table top, depending on the desired length of the table 1, may be greater than for the divided table top version, but the choice of dimensions can be made according to the size requirements of the product anyway .
  • the blank 20 or 2130/2140 has a rectangular basic shape and comprises, delimited from one another by conventional creasing lines 4, the two side surfaces 212 and the two parts for forming the table surface 211. The latter adjoin the latter, delimited by folding or creasing lines 216, with folding tongues 215 , which also extend over the entire length of the table.
  • the erection process of this blank can be seen from the left part of FIG. 4.
  • the side surfaces 212 are folded at an obtuse angle to one another, whereupon the two table surface parts 211 form the horizontal table surface be folded in.
  • the folding tongues 215 are folded down about the fold line 216 against the crease line 4 separating the two side surfaces 212, so that they extend essentially vertically downward from the table surface 211 and form a longitudinal or symmetrical axis of the table between them.
  • the wrap of the table top 2 formed in this way is locked from the free ends by the end elements 22, which are folded from an end element blank 220 shown in FIG. 8.
  • This blank has an end face 221, two tabs 222 substantially corresponding to the table top parts 211, which leave a slot 223 between them, and two side tabs 224 corresponding to the side faces 212 of the table top 2.
  • the slot 223 is dimensioned such that the tabs 222 receive the two inwardly folded folding tongues 215 between them and thus lock them in a form-fitting manner, the positive connection due to the restoring forces of the corrugated cardboard being added to this form-fitting.
  • the dimensions of the blanks 20 or 2130/2140 on the one hand and 220 on the other hand are each to be selected in accordance with the desired geometric shapes of the table top 2.
  • the folding tongues 215 have such a height (distance between the folding line 216 and their free edge) that they extend to the base of the table top, that is to say the line 4 between the two side surfaces 212 and thus the apex of the angle between the latter. As a result, they form a support for the table surface 211.
  • folding tongues lie close together; it is of course possible, if necessary, to connect them to one another from the inside by stapling or gluing, but in the case of a tabletop which is undivided in the longitudinal direction, the locking of the shape by means of the end elements 22 inserted from both sides is in principle sufficient.
  • connecting elements 217 are connected to the two triangular in cross section for connecting the two top parts . i.:- gene longitudinal cavities inserted between a table surface part 211, a side surface 212 and a folding tongue 215.
  • connecting elements 217 are hollow bodies with a triangular profile, which is precisely adapted to the size of the cavities in the table top.
  • the length of these connecting elements 217 will be chosen so that a sufficient positive connection between the plate parts 213 and 214 is achieved.
  • the three surfaces of the connecting element 217 can be selected in the arrangement shown in FIG. 6, the divided surface possibly being connected to one another, although folding the blank 2170 into the shape shown in FIG. 4 is sufficient due to the restoring forces of the material, in order to achieve a firm connection between the two plate parts 213 and 214 as a result of the non-positively acting restoring forces to be added to the positive connection.
  • support blanks 30 are provided according to FIG. 7, the four supporting walls 31, on the upper edges 33 of which there are contact tabs 331 for the side surfaces 212 and on one of their free edges 34 a connecting link 341 for mechanical connection with the supporting wall 31 adjacent in the erected rhombus include.
  • This mechanical connection also follows by gluing or stapling.
  • a ring body which can be packed flat can also be produced from this support blank 31, which merely needs to be pressed into the correct shape by the user of the table.
  • the hatched sections in FIG. 1 and in the cut representations of FIGS. 5 to 8 show the wave shape in the corrugated cardboard sections. This is chosen with regard to the main load directions, so that there is a standing wave for the folding tongues 215, the supporting walls 31 and the vertical legs of the connecting elements 217, and thus optimal load conditions are ensured.
  • the cuts shown can be partially pre-assembled by the manufacturer in the manner described above (in particular the plate part cuts 2130/2140 and the support cuts 30) and put together overall to form a pack ready for shipment, so that the user can quickly raise the table to its final shape without any particular problems to have manual skills.
