Description

Folding railing for beds.

Object of the invention

The present invention relates to a folding railing for beds, especially for beds hospital.

The main object of the present invention is provide a sturdy and safe design railing that guarantee your positional stability in your upright situation, without that there are slacks or unwanted movements. It is also about provide the railing with a tightness that prevents the entry of dirt in some of its constituent elements, as well as impingement and entrapment during dejection of the railing.

Background of the invention

The handrails or barriers of protection used in hospital beds preferably, which They aim to prevent patient falls.

Folding or folding type railings facilitate its retraction to allow the possible access or exit of useful accessories for the patient, as well as the approach of people who can assist you. You are preferably railings are constituted from extreme uprights that are joined by a series of parallel stringers forming a structure as an articulable parallelogram, which in position upper or upright protects the patient and in his retracted position It is hidden at the level of the bed base.

Some solutions are known to ensure the top position of the folding railing, just as is described in utility model ES 1059121, in which describes the use of a telescopic tube that associates the means of fixing the termination of one of the uprights with the crossbar bottom and that is equipped with locking means that ensure the top position of the railing.

On the other hand in general it has been verified that the union between the folding railing and the bed base constitutes a important point to ensure the stability of the railing in its upper or upright position, and therefore the rigidity of the set.

In some folding railings it has been detected that the union between the railing itself and the bed base ends up presenting a slack that determines a mobility of the unwanted railing in transverse direction when it It is in an upright position. This situation conveys a instability and consequently a sense of insecurity for the user.

It is known that the union between railings and box spring is established with corresponding intermediation clamps that are positioned at the proper distance in the bed frame stringer and on which the ends are screwed bottom of the rails of the railing. Normally the union between these pieces it is established in a timely manner, being defined on that end of the stud a bushing that is pierced by a screw that fits into a plate that extends inferior to the clamp.

On the other hand some solutions are known concerning the articulated joint between the stringers and the uprights that present, among others, entrapment problems motivated by the particular design of these joining means that consist mainly in flat extensions that start parallel of the amount between which the end of the crossbar is articulated with the intermediation of a pin that crosses these extensions and stringer. The stringers are normally open by their extremes which means dirt can penetrate as well as they can cause impingement or entrapment between these extensions and the crossbar.

Description of the invention

The folding railing object of the present invention comes to solve the problem described above satisfactorily by incorporating means of fixing the structure of the railing to the bed base that guarantee stiffness and robustness in the union, avoiding the appearance of slacks and unwanted movements of the railing, as well as this railing presents some joints between stringers and uprights optimized to ensure the tightness in stringers and the security during his dejection thus avoiding entrapments unwanted

More specifically the folding railing, it is configured by a structure formed by uprights and stringers that articulate by their ends in those uprights and by a clamp that has fixing means that fix your position on the bed frame stringer. In accordance with the invention it is expected that the amount ends at its lower extremity in  a wide cylindrical surface equipped with a flat rear base which is applied and screwed against a vertical sector of the clamp, establishing a wide contact surface that guarantees stiffness and robustness in the joint.

The anterior base of the cylindrical surface It has a cover that covers a screw that fixes the surface cylindrical to the clamp. On the other hand the clamp comprises in general a stepped profile that shows a sector in U that it is crossed by a screw that fixes the position on the bed frame stringer, which extends into a central sector horizontal from which the lower part is extended mentioned vertical sector of flat surface.

The clamp configuration, especially the wide flat surface of contact with the cylindrical surface of the amount favors a reliable union absent of clearances during the articulation of the railing structure with respect to the clamp.

Another aspect of the invention relates to to each of the stringers of the structure ends in some bushings that fit externally at the ends of said stringer, which are equipped with facing projections among which is a flat extension that extends from the upright, in which said projections and the flat extension They are crossed by a joint. Unlike others solutions guarantee the tightness of the stringer, preventing dirt entry, as well as preventing them from occurring entrapments

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to an example preferred practical implementation of it, is accompanied as integral part of that description, a set of drawings where with an illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a perspective view partial of the railing constituting the object of this invention in which the union system used between the upright is appreciated and the bed frame stringer.

Figure 2.- Shows a perspective view front of these fixing means represented in the figure previous.

Figure 3.- Shows a perspective view rear of these fixing means.

Figure 4.- Shows an elevation view of the fixing means without the cover.

Figure 5.- Shows a detailed view in the that the articulated joint between the stringers and one of the uprights

Preferred Embodiment of the Invention

In view of the figures described then a preferred embodiment of the railing folding that constitutes the object of this invention.

Figure 1 shows a partial view of the folding railing, which is configured by a structure (1) formed by uprights (2) and stringers (3) that articulate at their ends in those uprights (2), as well as some handles (4) that facilitate the reduction of the structure (1). Additionally the railing has a clamp (5) that it has fixing means (6) that fix its position on the bed frame strut (7) to which the railing is fixed.

Figure 2 shows that the amount (2) ends at its lower extremity on a wide surface cylindrical (8) equipped with a flat rear base (11) and has its anterior base of a cover (9) covering a screw (10), shown in Figure 4, which fixes this surface cylindrical (8) to the clamp (5).

As can be seen in figures 2 and 3, clamp (5) consists of a stepped profile showing a U sector (5.1) that is crossed by a screw (12) that fixes the position on the bed frame stringer (7), which is extended in a horizontal central sector (5.2.) from which in turn inferiorly extends a vertical sector (5.3) of flat surface with which the flat rear base (11) of the cylindrical surface (8) in the fixing situation of the structure (1) of the railing on the clamp (5).

On the other hand, according to another of the characteristics of the invention represented in figure 5, are note that each of the stringers (3) of the structure (1) ends in some bushings (13) that fit externally in the limbs of said stringer, which are provided with protrusions (14) faced between which an extension is found flat (15) that extends from the amount (2), in which said projections (14) and the flat extension (15) are crossed by a joint (16).
