Abstract

Modular block of fractionable universal electrical boxes capable of being split at will and suitably into an appropriate number of portions, parts or parts, characterized in that it comprises a uniform battery of hollow elements 2 equal to each other and preferably of configuration regular, aligned longitudinally and transversely in an unlimited number of parts assembled and connected to each other along their adjacent and contiguous edges by means 6 liable to break, tear or break at junction points thinned for this purpose. The difference or distance between two axes of symmetry of the reticular alignment of the block 1, both longitudinally and transversely, is a constant dimension x and y, this distance preferably being 71 mm.

Description

- 1 -

  The present invention relates to a block of modules connected by splittable means breaking under an effort or a constraint

  determined or light in order to compose different games to the inde-

  miné of pieces suitably combining by isolating them from the general block by breaking or splitting according to the desired number. Logic-

  The block will include a variable and indefinite number of modules.

  According to the invention, the block is designed to be manufactured from a single piece or piece comprising an indeterminate number of regularly sized electrical connection boxes and distributed into appropriate lattice alignments, both longitudinally and transversely, to break or split the sets of boxes

  required at each installation point.

  In fact, the invention replaces, in a completely new and revolutionary version, the traditional junction boxes of electrical installations, so-called built-in electrical boxes, with regular round or square formats, made of light and insulating materials, such as bakelites or plastics, which are essentially spare parts provided with auxiliary or complementary means of joining them together

connect to each other.

  These means are generally nested, one female and the other

  male lying on diametrically opposite sides or points.

  These means are complementary to each other or complementary to one another, so that two or more connecting pieces come together

said means.

  However, although allowing multiple connections, the general arrangement of the interlocking or assemblies requires that

  these must be made in a mono-linear or unidirectional way.

  This means that it is impossible to associate or link to a row, a game or a single-linear combination.

other orthogonal combinations.

  The solution could consist of a combination as mentioned above, if the nested connecting or connecting means were also arranged in opposite directions. This solution would imply an increase of the material density of the box and the weight as well as the material, and would result in an increase in the price of the box and in the loss of the standardization of the dimensions,

  at least assembly, said boxes.

  - 2 - In any case, in addition to the disadvantages mentioned, the parts should be made individually (apart from the fact that a tool has several, depending on the cost) and would be sold as spare parts. It would then be up to the operator to connect them by fitting in advance the boxes he would like to connect,

  being always rigorously obliged to connect them unidirectionally

  LEMENT. As indicated in the first paragraphs of this memo, the invention essentially comprises a block with an indeterminate number and the reticular format of hollow pieces of regular configuration (empty boxes), preferably the traditional (circular) rounds, aligned and connected together. to others in longitudinal and transversal formations, the quantity of which will be repeated as many times as

will consider it relevant.

  Another feature of the invention consists in the fact that the axes of symmetry of the formations aligned in the longitudinal and transverse direction of said block of boxes have a constant and invariable dimension, which amounts to saying that the distance between

  the center (between axes) of said boxes maintains an equidistance allowing

  to determine that the recesses of these respect the

  standardized dimension common to all and that the external dimensions, both for one axis and the other, and whatever the number

  of split boxes used on the installation, be proportionally

  to that dimension meeting the requirements and determined by

Standard.

  With regard to the previous characteristic, the dimension

  constant is 71 mm. between the axes of symmetry, both longitudinal and

  than transverse, the distance between centers (between axes) of

  boxes being also, for any of them, 71 mm.

  Another feature of the invention is that said pieces are connected by their contiguous adjacent sides according to the sides coinciding in the aforementioned network association. These are means preferably arranged two on each side, near the corners or edges of the box and on the edge of the perimeter most

protruding from said box.

  Another characteristic lies in the fact that said connecting means or junction are breakable and breakable points

  in a preferential sense of breaking allowing their breakage or fractionation

  in a safe environment, under the easy action of a slight containte in order to isolate, according to the number and the combination

  desired, the connection boxes.

  One of the great advantages of the invention is that the multiple molding of identical modules involves a great saving in matrices and material and makes it possible to lighten the weight of the module, with considerable saving of material, and therefore the lower manufacturing costs that entails. The anchoring means for joining or connecting traditional boxes are eliminated?

  which avoids having to perform said operation.

  Another advantage is that all sides of the box are provided with thinner areas to open the mouths for connecting the insulating tubes. This makes it possible to install or mount at the same time as many nested boxes as is necessary and whatever their position. Thanks to the localization of the thin zones,

  two or more boxes can be made to communicate with each other.

  Many other advantages arise from this solution, as much in manufacturing as in assembly, storage, marketing or use. These boxes preferably have a vertical profile or staggered matrix narrowing downwards

  to allow vertical stacking of blocks or modules separately.

  We will have a more precise idea of the characteristics of

  the invention on reading the description which will follow, made in

  reference to the drawing plates appended to this memorandum and on which, in a somewhat schematic way, and only for

  for example, the preferred details of the invention are shown.

reticularly according to the invention.

  Figure 2 is a bottom plan view of the pairing mode of two

  modules represented one integer and the other partially.

  Figure 4 is a plan view of the mode of association and assembly

  of contiguous modules, according to formations distributed reticularly.

  -4- identical to regular hollow formats (built-in boxes for

  electrical connections) aligned in reticular formations, longitudinally

  along the axes of symmetry (x) and transversely along the axes of symmetry (y), so that, as shown in the diagram, the difference between the axes (x) and (y) is a constant and equal measure

  (=), this constant dimension between axes being preferably 71 mm.

  As a result, the modular element 2 has an approved capacity (Z) which is a standardized measurement or dimension to ensure varied and unlimited combinations of said boxes 2 without altering

  their practical possibilities of installation.

  These breaking or breaking means 6 are provided on the rim of the most salient periphery 9 (FIG 3) of the module, favoring their tendency to follow the direction of rupture to facilitate the splitting thereof.

  under the only sketch of the breaking effort in this direction.

  In the same way, the modular elements 2 are provided at the bottom and sides, wholly or in part, circular thin zones 7 to provide entries, access or holes for the passage of the arrival tubes. These thinned areas are provided with grooves

  8 of cross-section (Fig. 2-A) to facilitate said openings.

  The body of the module also includes staggered matrices descending towards the base to ensure the stacking of said modules, both in block and separated, regardless of the number. This invention being sufficiently described, it is specified for all practical purposes that it is not limited to the precise details of this presentation. On the contrary, we will make all the changes deemed relevant to the extent that we will not undermine

  the essential characteristics claimed below.
