Description

OBJECT OF THE INVENTION

The invention, as stated in the title of this specification, refers to a frame for electrical and/or electronic devices, which provides the function to which it is intended with several advantages and characteristics of novelty that will be explained in detail thereafter, that mean an improvement on the current state of the art.

The object of this invention refers to a frame of the type used to fasten electrical and/or electronic devices incorporated in boxes, such as for example those for flush mounting and those for surface mounting.

FIELD OF APPLICATION OF THE INVENTION

The field of application of this invention is within the sector of the industry engaged in the production of equipment, mechanisms, devices and their accessories of electrical and electronic material.

BACKGROUND OF THE INVENTION

Currently, the electrical or electronic devices that are installed within a box, use to be fastened by means of a frame that, constituted by a single body provided with a series of holes, is fastened by screwing it. This frame has a shape and dimensions coinciding with the shape and sizes of the box in order to remain fitted over it and so that the said holes, usually one on each side, remain coinciding with the cavities provided in the box to screwing the related screw.

The problems that this invention seeks to solve are those arising by the fact that, when they are installed to fasten several electrical or electronic devices, a recessed space available in the wall is required to install each of the related flush-mounted boxes to fasten each device and only one device fastening or connection access is available from outside.

Therefore should be desirable, to have a common frame available for all the flush-mounted boxes to be installed in each case, cutting down costs and making installation easier as it reduces the number of elements and fastening operations to be carried out, but that in addition allows to extend the fastening or connection of a number of electrical and/or electronic devices greater than the number of flush-mounted boxes to be installed in the wall, allowing to make better use of the space and providing the element with a greater versatility.

As reference to the current state of the art, it can be pointed out that however different types and models of frames for flush-mounted boxes are known, the existence of any having technical and structural characteristics similar to that herein presented and claimed is not known.

EXPLANATION OF THE INVENTION

The frame for groups of flush-mounted boxes that the invention proposes, is therefore configured as an outstanding novelty within its field of application, and when it is implemented the above objective mentioned as ideal is satisfactorily reached, the characterizing details making it possible and that distinguish the said frame, being suitably included in the final claims attached to this specification.

In an embodiment of the invention, the frame, which aim is fastening electrical and/or electronic devices in flush-mounted boxes, has a structural configuration consisting in a single body provided with at least two holes to fit the devices with fastening means to be fastened on at least one flush-mounted box, provided with a number of holes to fastening electrical and/or electronic devices greater than flush-mounted boxes, so that at least one hole of the frame is not associated to a box and therefore only one of the holes comprises fastening means adapted to fasten the frame.

This arrangement provides the advantage to allow fastening elements, that is to say, surface electrical and/or electronic devices, in addition to avoid installing a flush-mounted box for each fastening point.

In addition, according to another characteristic of the invention, the said frame, at least in the part incorporating the hole or holes that are not directly associated to a flush-mounted box, has a separator element that avoid the frame to directly contact the said flush-mounted boxes, when the frame is already fastened on the frame of the box.

This allows being able to pass cables through the assembly, from one of the flush-mounted boxes to the surface element that is fastened on the frame without being directly associated to a flush-mounted box.

Last, it shall be pointed out that the said separator element is preferably constituted by folding the material itself of the frame on at least one of its perimetral edges, at least on the area of the hole to fastening surface elements without being directly associated to a flush-mounted box, and preferably on the longitudinal edges.

The separator element allows that the surface of contact of the frame with the wall is reduced, because, contrary to the conventional systems, in which the full internal surface of the frame is that making contact, now, it is only the tip of the edge that is making contact with the wall, which in turn improves the frame stability, because its fastening on the wall will be affected by the irregularities thereof to a lesser extent.

Ultimately, the frame of the invention is specially devised to fasten electrical and/or electronic devices on one or several boxes, consisting, as an essential feature, in a single body provided with holes in which electrical and/or electronic devices are fastened, a number of holes existing on the frame to fastening the said electrical and/or electronic devices greater than flush-mounted boxes, so that, at least, one of the said holes is not associated to a flush-mounted box allowing to fasten surface electrical and/or electronic devices.

In another embodiment of the invention, the frame in addition has a structural configuration that, instead of being coupled to be individually fastened over a single box, is coupled to one or several boxes making up a group of at least two boxes attached and better if they are linkable to each other, constituting a frame that, advantageously, allows the simultaneously fastening of every and each of the said boxes that make up the said group.

The frame for groups of boxes disclosed therefore consists in an innovating structure having features unknown up to now for the aim to which it is intended, reasons that jointly, with its practical utility, provide it with sufficient ground to obtain the privilege of exclusivity applied for.
