Abstract

The invention relates to a levelling system for boxes for electrical mechanisms, comprising a bracket (1) formed by two plates (2, 6) arranged at a right angle, joined to one another by a break line (10). The plate (6) is coupled via pressure to the lateral wall of the box (C) by means of a hook (4), parallel projections (8) and ledges (11) accommodated in a groove (S) of the box, guaranteeing the securing and alignment thereof. The wall plate (2) is provided with an oblong slot (3) which allows a levelling line painted on the wall to be seen, and a perforation (14) through which a screw passes, associated with a block (12), temporarily securing the assembly during setting. Once the box is mounted and levelled, the plate (2) is manually removed, breaking at the line (10), leaving the box embedded in the wall and the surface clean, without visible elements.

Description

[0001] DESCRIPTION

[0002] ELECTRICAL MECHANISM BOX LEVELING SYSTEM

[0003] Object of the invention

[0004] The present invention relates to a new leveling system comprising a set of parts that are fixed, on one side, to a wall and, on the other side, to an electrical mechanism box and allow leveling of an electrical mechanism box in situ on the said wall.

[0005] The invention falls within the industrial sector related to accessories, systems and equipment used in the assembly of electrical installations.

[0006] Background of the invention

[0007] As is widely known, electrical boxes are enclosures, usually made of plastic, that are recessed into a wall and serve as housings for electrical accessories and mechanisms such as sockets or light switches. These boxes are modular enclosures with an open front, and their side walls include a plurality of grooves or ribs for reinforcement and secure mounting to the wall.

[0008] In this regard, when it comes to leveling these boxes, especially those with multiple front modules arranged in a line, there are no known accessories or systems that guarantee level installation on-site. It all depends on the installer or electrician, who must position the box straight and level, using tools such as a level and / or a profile.

[0009] Since the box is recessed into the wall, the problem is that if the box is not properly leveled, there is no way to correct the unevenness, and the light points are not visually straight, but crooked.

[0010] Given this existing problem in the prior art, the present invention solves this problem by developing a set of parts that allow for on-site leveling of the junction box using a visual mark. This visual mark is a level line, previously painted on the wall by the electrician, which is a straight and level line. Once this level line is painted, the hole for embedding the junction box can be made in the wall. Following this, the system of the present invention, which is press-fitted to the junction box, comprises a part that allows the aforementioned level line to be visualized. Therefore, it allows the junction box to be fixed to the wall in such a way that the level line is aligned with the part of the system, thus leveling the junction box.

[0011] The applicant is unaware of any solution that is similar or as advantageous as the one described and claimed below.

[0012] Explanation of the invention

[0013] The invention is designed to ensure that an electrical mechanism box that subsequently houses an electrical point is leveled in situ, that is, that once the work is finished, the light point is straight.

[0014] To solve this problem, the leveling system advocated in the present invention comprises a bracket that is fixed by pressure to a side wall of an electrical mechanism box and where this bracket has a means that allows visual leveling by an operator from outside the bracket, and also comprises a plug that is fixed to the bracket and allows the operator, after leveling the bracket, to fix the system to the wall.

[0015] Going into greater detail, the bracket, which as previously indicated is fixed by pressure to a side wall of an electrical mechanism box, is a piece of plastic material with two plates at a right angle, consisting of a support plate on the wall, comprising a longitudinal oblong groove, which is arranged on a level line previously painted on the wall and, therefore, said groove allows a user to view the level line from the outside and level the plate; and, at least one hook at one end, the rear face of which is in contact with the inner face of the side wall of the box; and where the hook may comprise a reinforcing rib on its front face;a support plate, which extends perpendicularly from the support plate, comprising parallel projections in contact with the lower face of the support plate and arranged on the front face of the support plate, and remaining in contact with the outer face of the side wall of the box, preferably fitting into a reinforcing groove of said outer face, and having a separation slot between the inner face of the hook of the support plate and the front end of the parallel projections, a groove into which the side wall of the electrical mechanism box fits; which may comprise reinforcements in contact with the lower face of the support plate and arranged on the rear face of the support plate; comprising a transverse groove arranged below the reinforcements, which is a break line so that the bracket can be broken at that point;and parallel protrusions arranged at the lower end of the support plate and on its front face, which are in contact with the outer face of the side wall of the box, and preferably fitted into the reinforcing groove.

[0016] On the other hand, the wall fixing plug, which is a solid plastic body comprising a protruding tip on its upper face that fits into the oblong groove on the lower face of the support plate; and comprises a through hole centered in its body, which allows a user to screw it in from the outside of the plug and the support plate to the wall; and may comprise lateral reinforcing flanges to secure the support of the plug to the wall.

[0017] In a preferred embodiment of the invention, a leveling system is arranged on each side of a mechanism box, so that the continuity of the level line painted on the wall can be visually checked in the longitudinal oblong grooves of the support plates on the wall on both sides of the box.

[0018] Regarding the system assembly and on-site installation of the electrical box in the wall, the process begins with an electrician or bricklayer painting a level line on the wall and drilling a hole where the box will be installed. Once the leveling system is fitted to at least one side of the box, the box is placed in the hole, and the user positions the oblong longitudinal grooves of the mounting plates in the wall so that the level line is visible within the groove. Next, using a screw positioned along the painted level line, the system's anchor is secured to the wall on both sides of the box. This fixes the mounting plates in a level position, thus leveling the box. The operator can then fill the hole, ensuring the box is flush with the wall and perfectly level.After this, the support plate is manually pulled apart, and this effort causes the support plate to break along the break line and the entire support plate to be removed, leaving only the box embedded in the wall visible.

[0019] It should be noted that, throughout the description and claims, the term "includes" and its variations are not intended to exclude other technical features or additional elements.
