Description

Framework intended to house a box of electrical connections and the like.

This utility model refers to a framework designed to house a junction box, mechanisms electrical, and similar, conceived and designed for installation embedded in false floors, and whose essential characteristics are described below.

In the modern interior installations of power supply networks, as well as data transmission and audio, so-called "floors" are increasingly used technicians "or" false floors ", consisting of a set floating, formed by a network of metal profiles, which They level perfectly thanks to the adjustable feet that the set, placing, on said framework the slabs that they will constitute the soil surface. Obviously included here floating platforms and the like.

This embodiment allows, since there is a adequate space between the false floor slabs and the pavement, quickly and conveniently install the wiring of the different power, data and / or audio networks, said networks being accessible at any time to be able to lift the slabs with ease.

In these embodiments it is of basic importance have adequate boxes, sufficiently protected, embedded in the place required and fixed in its place of location, boxes inside whose mechanisms are connected with the corresponding network located under the false floor, remaining, in certain embodiments, visible from outside the surface of the box, only the elements of the mechanism that they must be accessible to the user, such as plug bases and of connection, switches, push-buttons, or the like, or, in other embodiments, will be fully covered by a lid practicable, allowing access to the user inside the box.

The object of the present invention is to a perimeter frame that allows assembly, installation and fixing on the false floors, of a junction box in the embodiment concrete box, without using, as in the Nowadays, given the characteristics and limitations of the existing devices, adjustable connection or registration boxes in height, nor that they should be fixed to the floor by means of elements complementary, more expensive to develop and in the methodology of its installation.

The special arrangement of the perimeter frame, essential feature of the set, allows the placement of the box, which, once installed and firmly attached to the slab of the False soil, is level and flush with the surface of it. This box can then be placed at any height of the false floor, without the need for height adjustable records.

In order to describe the various elements that make up the whole framework object of this invention and its junction box, some drawings are attached in the that, as a non-limiting example, a practical realization of it.

In these drawings,

Fig. 1 is a perspective view and explosion of the assembly formed by the framework of the invention and the junction box showing all its components;

Fig. 2 is a perspective view above of the bucket placed on the frame, also being placed the claw-claws for fastening to the false floor with the corresponding screws;

Fig. 3 is a view, also in perspective of the bucket and frame, according to the previous figure, seen by below;

Fig. 4 is a perspective view of the frame perimeter, hereinafter referred to as "frame", seen by over;

Fig. 5 is a view, in perspective and corresponding to fig. anterior, of the frame, seen below; Y

Fig. 6, finally, is a schematic view in partial sectional elevation of a part of a false floor with the set consisting of the frame and junction box.

According to these drawings, the set formed by the frame of the present invention and the box of recessed connections in false floor is characterized by consisting in a cuvette (1) of prismatic configuration and upper edge quadrangular.

This tray (1) is arranged embedded in the hole inside (2) of a quadrangular frame (3) on whose inner flange, constituted by a vertical flat wall (3a), fits in its said whole cuvette (1) by coincidence in dimensioning of its contour (1a) with said vertical flat wall (3a) of the frame (3).

This framework (3) that constitutes the basic element of the invention, it has a flat perimeter flange (4) that is supported by its lower face (4a) on the slab (5) of the false floor, in the that a hole of dimensions has previously been made suitable for fitting it, whose frame (3) supports the bucket (1) inside.

Inside the bucket (1), provided with proper tabs and highlights, the set of mechanism (6), of various configurations, depending on the installation that is being done, and given the versatility of the device.

This mechanism set is housed and conveniently installed inside the cuvette (1), which It is closed at the top by a flat cover (7) provided of an articulated central cover (7a), which allows, after opening, access to the inside of the mechanism (6 and of the cuvette (1) by of the user.

The flat areas (8) located in each of the corners of the frame (3) serve so that the bucket (1) is seated for the corresponding flat support areas (9) located in each one of its corners, thus avoiding that said bucket (1), together with the aforementioned mechanisms (6) installed inside, they can pass through the inner hollow (2) of the frame (3), and accidentally rush into the space below the slab (5) of the false floor.

The bucket (1) has on its underside, in each of the flat support areas (9), provided with recesses (9a) of the corners, two cylindrical lugs (10), that fit in holes (11), practiced and located in flat areas (8) of the corners of the frame (3), tapping on the holes (10a) of said lugs (10) cover closing screws flat (7), of the mechanism assembly (6), screws (7b) that are introduced through the corresponding holes of the own cover (7). Thus the lugs (10) are fitted in the holes (11)  Solidarity of the whole set with the framework (3), which will be installed through the hole previously made in the slab (5) of the false floor, being finally said frame (3) fixed properly to said soil, as has been pointed out more above.

The bucket (1) includes some nail tabs (12), located on the bottom edge of two sides of the vertical contour (1a) of said tray, the which fix by clipping on the vertical flat wall (3a) of the frame (3), allowing a pre-assembly of the cuvette (1), with the frame (3), facilitating the subsequent manipulation of the elements during the installation, while guaranteeing the perfect flush of the upper flat flange (4) with the upper face of the cuvette (1) and of its flat cover (7).

Some reliefs (9a) located in the flat areas of support (9) of the cuvette (1) are housed in the cavities (8a) of the flat areas (8) of the frame (3).

The arrangement of these flat areas (8) of each corner of the frame (3) in total coincidence with the zones flat support (9) of the cuvette (1) and cylindrical lugs (10) located there with the holes (11) of those mentioned flat areas (8) of the frame (3), where the lugs fit (10) allows the orientation of the cuvette (1) in the four positions possible, turning it every time, for this, 90 °, with the purpose of that the articulated central cover (7a) of the flat cover (7) can open in any of the senses, as required.

Claw-claws (13) serve to carry out the fixing of the assembly to the slab (5) of the false floor, acting on them by means of screws (14) placed through lateral holes (15) located in two of the sides of the upper face of the bucket (1). Those mentioned screws (14), are arranged inside the claw-claws (13), with washers provided (16) below them. These washers (16) prevent the claw-nail (13) can go down to the point that could break off and therefore fall. The tightening is done by the own claw-nail (13), since the screw (14) is encapsulated and cannot move, so by making said guide screw (14), the referred claw-nail (13) ascend or descend by finding the top of the frame (3) (not mounted) or the bottom of the tile (5) once mounted on the floor) and below the washer (16).

Once the assembly, tray (1) and frame (3), inside the opening previously made in the slab (5), it will act, using an appropriate tool, causing the claw-nail (13) ascend and press on the face bottom of said slab (5) of the false floor, fixing all the set and avoiding accidental displacement in the direction vertical of the same, proceeding at that time to mount e installation of the mechanism (6), together with the flat cover (7), remaining the entire device located in the built-in embodiment on the false floor, located on a conventional metal framework (17), provided with adjustable leveling feet (18), which they rest on the pavement (19).

Described sufficiently the object of the In the present invention, it should be noted that variations in dimensions, shapes, finishes and exterior appearance, as well as types of materials used in the practical realization of the box, nothing will alter the essentiality of it, which remains summarized in the following claims.
