    OBJECT OF THE INVENTION
    The present invention relates to a system for lifting and lowering furniture
    or parts thereof. More specifically, in the invention an electromechanical device specially designed for application in small auxiliary furniture has been devised, such as headboards, behind the sofa, hallways, bar furniture, side / front desks, aisle storage, room divider, rooms meetings, commercial exhibitors, television tables, etc., designed to gain space and storage, empower such furniture or parts thereof, from an inoperative and optionally hidden lower position or level, to a high and functional position or level . BACKGROUND OF THE INVENTION
    There are currently several lifting systems for resting surfaces of canapés and similar furniture, particularly couches and beds, which allows said resting surface to adopt two different positions: a lowered position in which the user can rest on said resting surface and an elevated position in which it is possible to condition said surface, for example by changing sheets or doing other similar tasks to make the bed, at a height that does not require the user to have to lean too much and, consequently, adopt an uncomfortable forced posture .
    There are already known beds and bed bases equipped with means to vary the height of their rest surfaces with a view to facilitating the work to be done on them. These means usually consist of the combination of connecting rods, springs and / or gas pistons installed in a fixed bed frame or bed frame.
    This type of beds and bed bases is especially required by the centers where a large number of beds are to be made every day. Examples of these centers are residences, hospitals and hotels, where it is important that the personnel performing this task are not forced to repeatedly adopt positions that violate their backs and can cause injuries. In the homes we have canapés and armchairs rest and sofa beds.
    It is also known to use dampers for part of mobile furniture in different configurations with viscous fluids, air dampers. As can be seen in documents JP0060272446, EP0430797, EP0841452 as well as DE4409716.
    Other lifting devices such as the one disclosed in utility model U0195980 which shows a lifting device for application to furniture parts, which is essentially characterized in that it is constituted by the combination between a mobile frame and a fixed frame, whose frames are related through at least two spindles that rotate freely on the fixture extending perpendicularly from it, and that are threaded into females. established in the mobile, with the particularity that the said spindles receive movement, through two gear transmissions, from an electric motor located in the fixed frame, said motor being governable through a polarity inverter, installed in the fixed frame, and three switches, located two of them on the fixed frame and the third on the outside of the furniture, all in such a way that the external switch starts the system and that the two internal ones stop it, one through a stop and another through a tensioner that, alternatively, hits the first switch and pulls on the second, when the mobile frame approaches and separates from the fixed one, respectively, being mounted on the mobile frame, in addition, a second stop and a second tensioner which, depending on the direction of travel of said mobile frame, produces the polarity inverter drive, at the end of each path.
    The utility model U201531073 reveals a device that allows a piece of furniture or module to move suspended, without guides at medium height or on the floor as required by other types of installations. This novelty allows the continuity of pre-existing floors without the need to embed or overlap guides on the floor that involve unevenness or grooves that hinder cleaning and alter the finish and aesthetics of the original floor; It also implies, in the face of traditional wheel-based installations, the novelty and benefit of not increasing structural loads, especially those on the surface of the ground, thus avoiding possible structural pathologies, or in the finishes (scratches or scratches produced by the wheels, or breaks and damages in ceramic finishes or other materials).
    The present invention presents a scissor-shaped lifting system, adapted to a piece of furniture that allows raising and lowering a set of compartments to accommodate objects from a compressed position at a lower height to an extended position at a higher height, with the In order to use the objects placed inside, this allows to keep the objects hidden and away from other people's reach and on the other hand it can be used in places where space is important, being optional to carry wheels for transport and anti-lock bolt unwanted openings.
    The furniture has a scissor-shaped system that adjusts by means of a support to a modular element and allows the furniture to be raised and lowered more easily and ergonomically without the need for the use of dampers or more complex elements. Known devices, however, require complicated manufacturing.
    or a high degree of precision. One part of this air damper has adjustable valves to adjust the compression pressure, while the other air dampers have complicated grooves or channels on the piston or cylinder wall, which can lead to rapid damage of the piston seal . DESCRIPTION OF THE DRAWINGS
    To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of the practical embodiment thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:
    Figure 1.- shows a view of the structure with the lifting system
    Figure 2.- shows a view of the structure and the various parts that make up the furniture.
    Figure 3.- shows a view of the furniture with the compressed lift assembly, where the arrow indicates the direction of movement.
    Figure 3.- shows a view of the furniture with the extended lift assembly, where the arrow indicates the direction of movement. PREFERRED EMBODIMENT OF THE INVENTION
    The lifting furniture of the present invention is formed from a metal frame or chassis structure (1) forming a rectangular parallelepiped, where said structure has in its lower plane a pair of parallel guides (2) in solidarity with the structure (1) for the incorporation of a lifting assembly (3) in the form of scissors. The lifting assembly (3) is fixed to the structure (1) by means of projections (10) and (10 ’) that allow the screws to be coupled.
    The scissor-shaped lifting assembly is constituted by an upper support (4), a lower side (5) consisting of a welded structure with a pair of central holes where inner diameter bushings of approximately 13 mm are housed, in each of ends of said lower side (5) there is an axis that extends beyond the connection hole generating a termination, where the termination of one of the axes joins the upper support (4) and the other termination is coupled to a pair of bearings (7) that fit the parallel guides (2) of the structure (1) for their displacement. The lifting assembly also comprises an upper side (6) consisting of a rectangular structure welded with a pair of holes in its center, where an axis for the cylinder is mounted in the center of the structure and contains a connecting bar (8) of the sides that provides greater rigidity. The upper side (6) also has an axis at each of the ends that extends beyond the connection hole generating a termination, where said termination allows it to be fixed to the base of the structure (1) by one end and to the upper support (4) by means of bearings (9) at the opposite end, and is connected to the lower side (5) by said axis of diameter approximately 13 mm defining the scissor shape.
    The axles are fixed both for the wheels and for the connection between the lower side (5) and the upper side (6) by means of elastic rings of the seeger type that allow a block to be locked inside a hole on A shaft in order to easily disassemble it.
    For the operation of the scissor-shaped elevator assembly, the system incorporates an electromechanical motor that allows the internal part of the furniture to be raised and lowered, where the motor is also remotely operated by means of a control.
    The system is completed with the formation of an elevator cabinet with the incorporation of side panels (11) and front panels (11 ') that are coupled in the metal structure by the sides of said structure and a modular shelf (12) with their respective shelves which is inserted in the upper part of the structure and is fixed to the upper support (4) of the elevator system, where said modular shelf (12) ascends and descends by means of the scissor-shaped elevator assembly.
    The elevator furniture is in a compressed initial position, where the modular shelf (12) is incorporated in the lower part of the elevator cabinet and by the drive of the electromechanical motor connected to the cabinet, the elevator assembly ascends the modular shelf (12) to a higher position and therefore the user can access the modular shelf (12) to store or acquire any object placed in it.
    The elevator furniture is completed with two side panels (11) and 2 front panels (11 ’) that are coupled to a metal structure in the form of a rectangular parallelepiped; a modular shelf (12) with its respective shelves that is inserted in the upper part of the structure and fixed to the upper support (4) of the scissor-shaped elevator assembly (3); an engine placed in the furniture; and a remote control in connection with said motor that allows it to be driven to ascend and descend.
