    [0004] FIELD OF THE INVENTION
    [0005]
    [0006] The present invention is framed within the technical field corresponding to lifting structures. More specifically, the invention refers, although without limitation, to a scissor-type mechanism capable of raising and subsequently lowering a bed, to facilitate cleaning and conditioning of beds without the need for great efforts on the part of a user.
    [0007]
    [0008] BACKGROUND OF THE INVENTION
    [0009]
    [0010] Beds, typically made up of a box spring and a mattress, are universal products present both in private homes and in certain businesses, such as hotels and hostels. As a general rule, they are heavy and static objects that, depending on their position within a room, can complicate tasks such as changing bed sheets or cleaning underneath. These characteristics can even become problematic when a single person has to carry out the work of fitting out dozens of beds and rooms in a few hours, as is the case, for example, in the hotel sector. In this context, on the one hand, it is necessary to improve efficiency in carrying out the tasks of cleaning the room and conditioning the beds, reducing the execution times of these tasks. Likewise, on the other hand, it is also necessary to improve the ergonomics of these tasks in order to avoid injuries to the personnel in charge, since in general, the height of the beds requires flexed and forced positions for the personnel, so that they can making the bed upright is an advantage in terms of comfort.
    [0011]
    [0012] Therefore, the present invention aims to improve efficiency and ergonomics in carrying out cleaning and conditioning tasks for beds and rooms, by means of a device that allows beds to be raised and moved easily and without great effort, allowing the floor to be cleaned under the bed, as well as making the bed at a comfortable height for one person.
    [0013] BRIEF DESCRIPTION OF THE INVENTION
    [0014]
    [0015] An object of the present invention refers, although without limitation, to a lifting device capable of raising and lowering a bed base and a mattress, where said device comprises at least one scissor structure, and where said scissor structure comprises at least one first bar and a second bar, where both the first and the second bar comprise a first end arranged to rest on a support surface and a second end arranged to support the bed base and the mattress. Advantageously, said device further comprises, at least:
    [0016] - a damper connected between each first bar and each second bar; - a pivoting lever connected to the scissor structure;
    [0017] - a lower stop element of the pivoting lever, arranged in the scissor structure;
    [0018] - an upper stop element of the pivoting lever, arranged in the scissor structure.
    [0019]
    [0020] Thanks to this configuration, a device is obtained that comprises two positions: an elevated position, where the bed is fixed on the lifting device at a height higher than that determined by the bed base and a low position, where the bed is fixed at a height determined by the bed base. Thus, the device is capable of stably raising and lowering a bed, simply by applying a slight upward or downward force. This allows a person to perform tasks related to cleaning the space under the beds and conditioning a bed after being used in upright positions, resulting in greater ergonomics and greater comfort.
    [0021]
    [0022] In a preferred embodiment of the invention, each of the first and second bars comprise, at substantially a first end, one or more wheels.
    [0023]
    [0024] In this way, a device is obtained that also allows the device and the bed to be moved around a room, facilitating cleaning of the room and accessibility to the bed, when they are longitudinally, for example, next to a wall.
    [0025] In a preferred embodiment of the invention, one or more of the shock absorbers of the device comprise any of the following types: hydraulic, pneumatic, elastic solid.
    [0026]
    [0027] In a preferred embodiment of the invention, the device further comprises an extensible support, arranged substantially at the respective second end of each of the first and second bars of each scissor structure.
    [0028]
    [0029] In this way, the device is easily adaptable to different bed lengths.
    [0030]
    [0031] In a preferred embodiment of the invention, the device comprises two scissor structures, which are preferably joined by at least two connection elements, where each connection element respectively connects the first bars of the scissor structures to each other, and the second bars of the scissor structures together.
    [0032]
    [0033] Thanks to these connection elements, the device is more rigid and stable.
    [0034]
    [0035] In a preferred embodiment of the invention, the damper is connected, by a first end of the damper, substantially to the first end of the first bar of the scissor structure, and the damper is connected by a second end of the damper in a substantially proximal position at the second end of the second bar of the scissor structure.
    [0036]
    [0037] In a preferred embodiment of the invention, the one or more pivoting levers are connected by a crossbar.
    [0038]

    [0042]
    [0043] NUMERICAL REFERENCES USED IN THE FIGURES
    [0044]
    [0045] In order to help a better understanding of the technical characteristics of the invention, said Figure is accompanied by a series of numerical references where, by way of illustration and not limitation, the following is represented:
    [0046]
    [0047]
    [0048] DETAILED DESCRIPTION OF THE INVENTION
    [0049]
    [0050] We now proceed to describe a preferred embodiment of the present invention, provided for illustrative but not limiting purposes thereof.
    [0051]
    [0052] A main object of the invention refers, as described in the preceding sections, and as represented in Figure 1 herein, to a lifting device, preferably suitable for lifting a bed base and a mattress. . In this way, the lifting device comprises two possible positions: an elevated position, where the bed is fixed on the lifting device at a height higher than that determined by the bed base, and a low position, where the bed is fixed at a height determined by the bed base.
    [0053]
    [0054] In a preferred embodiment, as shown in Figure 1, the bed lifting device generally comprises:
    [0055] - two scissor structures (1), where each of said two scissor structures (1) comprises at least a first (2) bar and a second (3) bar connected at one point by a pivoting connection, and where both the The first as the second bar (2, 3) comprise a first end arranged to rest on a support surface, and a second end arranged to support the bed base and the mattress, and where the two scissor structures (1) are joined together by means of two connecting bars (4);
    [0056] - a damper (5) connected between each first (2) bar and each second (3) bar;
    [0057] - a pivoting lever (6) connected to each first bar (2), where the two pivoting levers (6) are joined by a crossbar (7);
    [0058] - a lower stop element (8) of the pivoting lever (6), arranged on each second (3) bar;
    [0059] - an upper stop element (9) of the pivoting lever (6), arranged on each second (3) bar;
    [0060] - a wheel (10) arranged at each first end of each of the first and second (3) bars of each scissor structure (1), which allow the bed to slide comfortably when the device is in an elevated position.
    [0061]
    [0062] To facilitate the understanding of the invention, the operation of the device is detailed. When the damper (5) is closed, the damper piston (5) does not exert force or pressure and, therefore, the bed is fixed in the down position. To raise it, it is necessary to apply a small force in the direction of raising the bed to an elevated position. Once the raised position is reached, the pivoting lever (6) stops with the lower stop element (8), fixing the raised position of the bed. Thus, to return the bed to its initial position, it is necessary to raise the pivoting lever (6) to the upper stop element (9), and apply a downward force until the bed reaches the low position.
    [0063]
    [0064] Thus, the assembly formed by the pivoting lever (6), the lower stop element (8) and the upper stop element (9), acts as a safety mechanism. Said set fixes the bed, once said bed reaches one of the two raised or low positions, giving stability to the two positions of the device.
    [0065]
    [0066] To implement the invention, the shock absorbers (5) can comprise several types of different technologies, among which are the types: hydraulic, pneumatic, or elastic solid.
    [0067]
    [0068] In another preferred embodiment, the lifting device is capable of adapting to different bed sizes, since the device additionally comprises an extensible support (11) arranged substantially at the respective second end of each of the first and second bars (2, 3) of each scissor structure (1).
