Definitions

• the invention as expressed in the title of this specification, refers to a frame for electrical and / or electronic devices, which contributes, to the function for which it is intended, several advantages and characteristics of novelty, which will be explained in detail below, being an improvement on the current state of the art.
• the object of the present invention focuses specifically on a frame of the type used to fit electrical and / or electronic devices incorporated into boxes, such as flush-mounting and wall boxes.
• the scope of the present invention falls within the Industry sector dedicated to the manufacture of equipment, mechanisms, devices and accessories for electrical and electronic material.
• the fastening holes of the frame are slotted and have a wider end to allow the passage of the screw head which has previously been threaded into the box, so that, after placing the frame and passing the screw heads, these slide to the narrow area and then the screw is tightened.
• this configuration of the fastening holes, in some types of frame is curved such that placement of the frame is facilitated.
• some frames include additional or complementary fasteners, such as claws that fit onto coinciding protuberances provided in the boxes for this purpose.
• the problem that the present invention intends to solve is that which is given by the fact that, when two or more electrical or electronic devices are installed forming a group where the boxes of each device are incorporated attached to each other and, typically, the devices of said group are externally united by a common cover frame, the fitting of the mechanisms of these devices is accomplished by incorporating an individual frame fastened and screwed on each of said flush-mounting boxes, whereby the complexity of the installation is increased, and the number of components and consequently the cost thereof, both in material and labour.
• the frame for flush-mounting box groups proposed by the invention is therefore configured as a remarkable novelty in its scope and in the light of whose implementation the target previously identified as ideal is successfully reached, the characterizing details for implementation and distinguishing the said frame being conveniently listed in the final claims that accompany the present specification.
• the invention proposes a frame for fitting electrical and / or electronic devices in flush-mounting boxes, which presents a structural configuration that instead of being coupled to be individually fitted on a single box, innovatively, it is coupled to the boxes conforming a group of at least two attached boxes and ideally linkable to each other, forming a frame which advantageously allows simultaneous fitting to all and each of the mentioned boxes which constitute the group.
• the frame of the invention is configured as a single body whose peripheral edge has the shape and dimensions of the set of flush-mounting boxes constituting the group, and in which there are as many recesses as boxes in that group, arranged logically in same position so that they coincide.
• said frame has at least two holes which, once the box is installed, coincide with two holes of at least two boxes in order to fit the single body by screws to the group of boxes where installation takes place.
• the holes of the frame type can be slots and with a wider end in order to install the frame by sliding without the need of fully unscrewing the screws of the boxes.
• each recess preferably, four holes are contemplated for each recess, arranged two on each side of said recesses.
• the frame group can be installed in the 4 boxes with only two holes in the plate and two screws in two boxes of the group.
• Another advantage provided by the frame of the invention is that the surface which is installed in contact with the boxes is flat, thus the installation is facilitated by translation of the frame itself and, therefore, it is not necessary to have additional elements which increase its manufacturing complexity.
• the frame of the invention is configured especially for fitting electrical and / or electronic boxes arranged in groups of two or more boxes, consisting as an essential characteristic of a single body provided with holes in which all electrical and / or electronic devices of the boxes constituting the same group are fitted, thereby avoiding the use of one frame per box, which is what it is currently being used.
• the described frame for groups of boxes thus consists in an innovative structure having characteristics unknown until now for the intended purpose, reasons which linked to its practical utility, give it sufficient grounds for obtaining the privilege of exclusivity requested.
• Figures 1 , 2, 3 and 4 show a perspective view of an embodiment of the frame object of the invention, together with a group of flush- mounting boxes linkable to each other for which it is intended, showing the steps of a possible fitting thereof by screws with the holes located above and below each recess; and
• Figures 5, 6, 7 and 8 show respective perspective views of the steps of fitting this same embodiment of a frame, according to the invention, represented in the preceding figures, in this case showing the possible fitting thereof by screws inserted into holes in the sides of each recess of the frame.
• the frame (1) in question consists of a single body provided with holes (12) for the fitting of various electrical and / or electronic devices (not shown) in boxes (21) in this case, unitary flush-mounting boxes (21) arranged in groups (2) of two or more boxes (21) and linked together, one for each device.
• the frame (1) preferably has a peripheral edge (1 1) having the shape and dimensions of the entire set of flush-mounting boxes (21) which form said group (2), and at least having as many holes (12) as flush-mounting boxes (21) in said group (2), said holes (12) being arranged in a position coinciding with each of said flush-mounting boxes (21) thereby making it possible to fit in each one, the corresponding electrical or electronic device.
• each recess (12) there are four of the second holes (13, 13') located at diametrically opposite points, two to two, to coincide with the four screw points (22), conventionally (usually 2 or 4) presented by the unitary flush- mounting boxes (21) on the edge unit in their walls, so that each hole (12) has two second holes (13) in the longitudinal axis ( ⁇ - ⁇ ') and two more second orifices (13') in the transverse axis ( ⁇ - ⁇ ').
• said second holes (13, 13'), having a slot area with a wider end for the passage of the head of the corresponding screw (3), are arranged with the wider area always oriented the same direction in accordance with the axis of the hole (12).
• all the second holes (13) of the longitudinal axis ( ⁇ - ⁇ '), the top and bottom ones of each hole (12) of the frame (1) are oriented with the wider area to the same side, for example towards the left according to the example shown in the figures, and all the second holes (13') of all the side transverse axes ( ⁇ - ⁇ '), of each hole (12) of the frame (1) are oriented with the wider area to the same side, e.g. downwards according to the example of said figures.
