Abstract

Liftable bed, characterized in that it is constituted from two frames, one lower (1) and fixed, equipped with the corresponding support legs (3), and one upper (2) and liftable, which constitutes the support for the bed base on which the corresponding mattress rests, the upper frame (2) being related to the lower frame by means of lateral pairs of articulated arms (5 - 6) anterior and posterior, which are interconnected by means of crosspieces (5'- 6'), with the particularity that the previous articulated arms join articulatedly to a pedal in "U", (8), through its lateral branches, pedal in "U" (8) whose lateral branches rest in turn on respective lugs (4) emerging from the front legs (3) of the lower frame (1), while between the rear articulated arms and the stringers of the upper frame (2) are articulated respective respective pneumatic cylinders (9) stabilizing the bed in its position lifting elevation.

OBJECT OF THE INVENTION

The present invention relates to a lift bed intended for use in hotels, residences and similar places or establishments, a bed that has very simple structural characteristics that allow its change of position in order to allow the placement of clothes bed in the most comfortable way possible and without risk of injury, therefore increasing the efficiency of staff or employees and thus the production, avoiding casualties due to back pain, low back pain, etc.

It is also the object of the invention to provide a stable bed in its resting position, but which can be easily transported in its deployment position.

BACKGROUND OF THE INVENTION

It is known that the people in charge of making the beds in hotels and similar places are constantly flexing their backs when carrying out such maneuvers, which ends up having back pain, low back pain, etc., since the beds are located at a height too low so that these maneuvers are not harmful when performed for long periods of time.

In addition, it should be borne in mind that although there are beds that can vary in height, either they present complicated mechanisms that have a very negative impact on their price, or they are mechanisms in which two people must participate for such elevation.

Finally, in the specific field to which the invention refers, it is relatively frequent that the beds must be moved from one place to another, so that if the structure of the wheel is equipped with wheels it is not very stable in situation inoperative, while if you lack them, it is clear that your transfer requires

great efforts clearly undesirable.

DESCRIPTION OF THE INVENTION

The lifting bed that is recommended solves in a completely satisfactory way the problematic previously exposed in each and every one of the mentioned aspects, based on a simple but effective solution.

More specifically, the bed of the invention has a structure based on reinforced iron tubes, not requiring complicated electronic mechanisms for its operation in the raising and lowering of the bed, but that it is carried out mechanically, through of a pedal, maneuver that can be carried out by a single person in a comfortable and simple way.

For this, the bed of the invention is constituted by two racks, a lower and fixed frame, with support legs on the ground, and an upper frame with the power to rise and descend to the height of the lower frame, the upper frame being the which acts as a support for the mattress bed base itself.

Between two frames two pairs of articulated side arms are mounted that allow the upper frame to be raised and lowered, forming on each side of the bed an articulated quadrilateral assisted by the corresponding pneumatic cylinders, carrying out said lifting and lowering maneuver by the actuation of a "U" configuration pedal, located subsequently between two of the opposite and rear articulated arms, so that between said front arms and the upper frame stringers the said pneumatic cylinders that facilitate said lifting maneuver are mounted.

The lateral arms, articulated between both sides, are extended by their lower limb in respective appendages finished off in wheels that do not come into contact with the ground in a folded situation, but which, in the arrangement of unfolding the bed, come into contact with the ground , being therefore the legs of the lower frame those that take off from the ground, thus enabling the easy and comfortable movement of the bed of a

place to another.

As for the dimensional characteristics and height of the bed, these can be variable and even customizable, adapting in their fabrication to the desired sizes, both in height and in length and width of the bed.

DESCRIPTION OF THE DRAWINGS

To complement the description that will then be carried out and in order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof, a set of drawings is accompanied as an integral part of said description. where, with an illustrative and non-limiting nature, the following has been represented:

Figure 1 shows a side-top perspective view of a lift bed made in accordance with the object of the present invention in partial deployment arrangement.

Figure 2.- Shows a perspective view of the bed when the upper frame is completely raised

Figure 3.- Shows a perspective view of the bed with the upper frame in the lower position.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures summarized, it can be seen how the lifting bed of the invention is constituted by reinforced iron racks and baked, anti-bacterial and igtifuge paint treatment, to prevent wear and deterioration of the bed, specifically a lower frame (1), in which two stringers and an extreme crossbar participate and which has the corresponding support legs (3), and an upper frame (2) in which two stringers on which the bed rest rests on he who in turn

The bed mattress is supported, the latter elements that are not represented in the figures.

Both frames (1) and (2) are related to each other by means of pairs of articulated arms (5) and (6), the first of them considered as anterior and the second as posterior, with the special feature that between each pair of arms a crossbar is established (5'-6 ').

Both the front arms (5) and the rear arms (6) are topped off in an extension that has a wheel (7) that is automatically deployed in the lifting maneuver of the upper frame (2), therefore presenting said wheels a retractable character.

In addition, between the front side arms (5) a "U" pedal (8) is mounted for raising and lowering the upper frame (2), collaborating in said elevation pneumatic cylinders (9) that are fixed articulated between the rear arms ( 6) and the side rails of the upper frame (2).

The lateral branches of the "U" pedal rest on individual studs (4) that emerge internally from the legs (3) associated with the anterior end of the lower frame (1), so that said lateral branches articulate jointly to the anterior arms ( 5), so that with a simple combined movement of pushing down and back of the middle leg of the pedal with the user's foot, the lifting of the upper frame (2) is achieved, while the lowering maneuver is It is carried out by simple pressure on the mattress, since the mechanism is not intended for the bed to be used in its lifting position, but simply to facilitate the dress maneuvers of the same, as well as to facilitate its transport.

In this way, the bed is structurally simple, fully mechanical and without any additional element that requires a source of electrical energy or another source of energy, being easy to operate with little effort, without risk of any type of injury.
