Description

Manual lifting device for bases mattress

Object of the invention

The present invention relates to a device of lifting which is applicable for manual lifting of mattress bases with the purpose of facilitating the work of make the bed.

It is an object of the invention that the device for survey consists of an articulated structure that facilitate the almost vertical elevation of the base of mattress with slight frontal displacement to avoid bed linen contact with headboard during lifting, leaving a space between the mattress base and the headboard of the bed once the mattress base is raised so that facilitate the introduction of bedding in this sector and without increase the space occupied by the bed in the room.

Background of the invention

The use of beds is increasingly widespread which consist of mattress and mattress base that are housed in the receptacle of an upper access frame that may constitute at the same time an object storage place. For facilitate access to the interior of the receptacle normally these beds incorporate a lifting mechanism that elevates the base of mattress and fundamentally comprising a structure articulated in collaboration with a spring, preferably a gas cylinder.

There are various embodiments of mechanisms of elevation, as is the case of Utility Model ES 1 031 183, which refers to a lifting mechanism for bed bases and the like comprising two pairs of cranks facing each other articulated by one end on a base frame that houses the bed base and at the other end on the bed base itself, as well as said cranks have lateral lugs that constitute the articulated joint point for respective gas springs that articulate in turn with respect to the frame. When raising the bed base produces a progressive tilting of the cranks with respect to the frame, as well as a progressive angulation between the cranks and the gas springs that determines the rotation of the bed base during its elevation.

Another lifting mechanism is described in the Utility Model ES 1 027 487 comprising stringers fixed to a base in the form of a drawer or chest that join the bed base through two pairs of previous articulated bars and later, being united a previous bar with a bar rear using a gas cylinder that acts as a pusher or set damper. The bars and bowler meet dimensioned and related so that the elevation or descent of the set is done in the vertical direction.

The Utility Model ES 1 029 946 also describes a lifting mechanism for bed bases and the like that It has adjustable length stringers for its adaptation at different lengths of the mattress base that they find related by crossbars and that through connecting rods  articulate with respect to the frame, facilitating the maneuver of horizontal elevation by means of gas cylinders linked by one end to a fixed support of the frame and on the other on a nut that moves in a spindle parallel to the connecting rod.

All these mechanisms present in common that they are applicable for those embodiments that incorporate receptacles in which the mattress base and the own mattress But in addition to vertical displacement, they displace The mattress frontally.

On the other hand the conventional bed equipped with a fixed frame with legs turns out to be the most commonly used, this type of bed has a height relative to the ground that results insufficient to make the work of making the bed comfortable. In the case of hotel establishments is a proven fact that the personnel in charge of making the bed suffer pain and to suffer injuries due to the need to bend your back permanently during repeated execution of these work

On the other hand the space available for Installation of the beds is in many cases limited, so in If the bed incorporates a lifting mechanism, you should take into account that the bed in raised position does not occupy more space than it occupies when it is pick up

The development of a lifting mechanism for lifting of mattress bases in beds equipped with this type of fixed frame with legs makes the invention feasible that described below.

Description of the invention

The manual lifting device for bases of mattress that constitutes the object of this invention offers an alternative solution to lift the mattress base in vertical direction with slight tilting in order to avoid rubbing of the bedding with the headboard, placing it in a position elevated that facilitates the work of making the bed without needing tilt your back or lean it minimally and without increasing the occupied space.

The lifting device consists of a articulated crankset structure that facilitates, in collaboration with a spring, preferably a gas cylinder, the manual raising and lowering of the mattress base with respect to fixed bed frame, incorporating essentially couples connecting rods to the fixed bed frame, incorporating mainly a pair of front and rear cranks facing that articulate at their lower ends with respect to the sides of said frame and have sliding in their  upper ends that support profiles associated with mattress base sides.

The cranks have lugs to which link the ends of some gas cylinders that on the other limb are fixed to the support legs of the fixed frame, the which facilitate the maneuver of raising and lowering the base of mattress

On the other hand it is contemplated that in order to control frontal displacement during lifting and descent, tie rods associated with connecting rods they are linked by its other end to the lateral profile of the mattress base.

The previous cranks as well as the cranks later, they are related to each other by means of bars stiffening, and in turn the previous cranks are related with the rear cranks by means of compensation bars that They relate the movement of both cranks. These bars compensation are linked to the cranks with intermediation of some connecting rods in connection with the connecting rods with respect to whose free ends articulate said bars.

The particular arrangement of the elements referred facilitates the articulation of the device by determining a vertical displacement with slight displacement front for separation from the headboard.

Preferred Embodiment of the Invention

The manual lifting device mattress bases constituting the object of this invention is application between a fixed frame (1) equipped with support legs (4) and a mattress base (2) for lifting the latter Regarding the first.

The lifting device consists of a structure based on pairs of front facing cranks (3) and rear (3 ') that articulate in the fixed frame (1) and have at its upper ends with some support studs (7) that they support some profiles in L (8) associated to the sides of the mattress base (2), as well as to said L-profiles (8) they link the ends of braces (9) which in turn articulate at its other end at the rear cranks (3 ').

Each of the connecting rods (3), (3 ') has a lug (5) that links to one of the ends of a cylinder gas (6) that facilitates the lifting and lowering of the base of mattress, as well as each of the gas cylinders (6) is fixed by its end to the fixed frame (1), the movement being made of the mattress base (2) in vertical direction with light front displacement to avoid contact of bedding with the headboard (14) of the bed during its movement, leaving a separation between the headboard (14) and the base of mattress (2) in its lifting position that facilitates the work of make the bed.

On the other hand the connecting rods (3), (3 ') that form part of the same couple are related to each other through intermediate stiffening bars (10) and lower (11), and at their Once the previous cranks (3) are related to the cranks rear (3 ') by means of compensation bars (12) that They relate the movement of both types of connecting rods.

The compensation bars (12) are located related to the connecting rods (3), (3 ') with the intermediation of some connecting rods (13) linked to connecting rods (3), (3 ') and on whose free ends articulate said bars (12).
