Definitions

  • the present invention relates to a frame for supporting table tops, comprising structural elements that when properly connected to each other, give to the frame different geometrical configurations.
  • writing desks and tables comprise a working top supported by a frame having a plurality of legs resting on the ground.
  • the frame generally comprises a plurality of structural elements consisting of beams provided at the ends with joints allowing their mutual connection through fastening means such as adhesives, screws and so on.
  • the main drawback of the known frames consists in that the beams must be designed and manufactured according to the different geometries of the frame to be produced, depending on the type of table or writing desk to be supported by said frame.
  • a further drawback connected to the preceding one consists in that these structural elements of different type oblige to use different packagings according to their geometry, especially when the table is sold and shipped in a disassembled condition, so as to increase again the total selling price.
  • the object of the present invention is to remove the above mentioned drawbacks.
  • a first object of the invention is to provide a modular frame for supporting tables allowing to carry out many different geometrical structures to be associated to different shapes and sizes of table tops, although said frame consists of a limited number of different connected structural elements.
  • Another object is to provide a modular frame to which support boards and supplementary accessories such as phone or video supports and so on may be anchored.
  • a further object is to provide a frame that can be assembled in a simple and quick way even by an inexperienced person like the common end user.
  • Another object is to provide a modular frame to which the table supporting legs can be removably associated.
  • a modular frame for supporting table tops that according to the main claim comprises one or more structural elements connected to each other at their ends through joint means, said frame being characterized in that each structural element comprises a beam provided with a flange at one end and a counterflange at the other end, so that each structural element can be connected to another element through joint means connecting said flange belonging to one element to said counterflange belonging to the other element to be connected, said joint means allowing the mutual rotation of said structural elements on the plane defined by said frame so as to form different geometrical configurations.
  • the flanges and counterflanges are each provided with grip means consisting of protrusions adapted to be coupled to corresponding seats made on their contact surfaces and adapted to prevent the mutual rotation of the structural elements so as to define a plurality of predetermined forms.
  • fastening means allow to block the structural elements in the selected positions.
  • the present invention allows to carry out with a limited number of structural elements even of different length, frames having different geometrical configurations and forms that can be fitted to the various tops. Still advantageously the invention reduces the number of production versions, and in comparison with the traditional tables reduces considerably both the production and storage and shipping costs of the product. Said objects and advantages will be better understood by reading the following description of a preferred embodiment given as an illustrative and non-limiting example by making reference to the accompanying sheets of drawings in which:
  • FIG. 1 is an isometric view of a writing desk provided with the modular frame of the present invention
  • - Fig. 2 is a longitudinal sectional view of a structural element of the frame of Fig. 1 ;
  • - Fig. 3 is a partially sectional plan view of the structural element of Fig. 2;
  • - Fig. 4 is a cross sectional view of the joining points between two structural elements of the frame of Fig. 1 and a frame support leg;
  • FIG. 1 is a sectional view of the structural element connected to another joining member with the frame of Fig. 1 ; and - Figs. 6 to 10 show different geometrical configurations carried out with some structural elements of the modular frame of Fig. 1.

  • Said frame comprises three structural elements 2 consisting of beams 21 , 22, 23 mutually connected at their ends through joining means shown in detail in Figs. 2 and 3, generally indicated with reference numeral 3 and supported by legs 4 resting on the ground.
  • each structural element 2 has at one end a first flange 3a to be coupled to a corresponding counterflange 3b belonging to a similar adjacent structural element 2 so as to allow the mutual rotation of the structural elements 2 about a perpendicular axis 5 defined by the joining means 3 that subsequently block said elements in the desired orientation.
  • the structural elements 2 take different geometrical configurations so as to match the support form to the form of the top P as shown in detail in Figs. 6 to 10 and better explained hereinafter.
  • each flange 3a and counterflange 3b is provided with grip means 6 shown in detail in Fig. 3.
  • These grip means comprise protrusions 61 belonging to counterflange 3b and radial seats 62 belonging to flange 3a adapted to be mutually coupled according to a selected direction.
  • Coupling between seats 62 and protrusions 61 blocks the mutual rotation of each structural element 2 so as to define a plurality of predetermined mutual positions of the structural elements 2. This allows the user when assembling the frame 1 , to place easily the structural elements 2 in the predetermined mutual positions chosen by the manufacturer according to the model of table or writing desk.
  • the user blocks the mutual position of the frames through the joining means 8 shown in detail in Fig. 4.
