Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slatted bedstead, particularly to a bedstead of an orthopedic bed, and a slatt used for the bedstead.

[0002]

Bed slats with slats are usually made of wood and have only a plurality of slats or bars that rest on a rigid frame. Slats
It is made of flexible wood, so that it flexes and bends in the opposite direction when the user's weight is applied, usually with a concave surface bent downwards. In such a construction, the flexibility of the bedsted is obtained by the deformation of the slats which bears the weight of the user. This deformation is always limited and does not fit the body shape well in both the longitudinal and lateral directions.

Therefore, the effect obtained from such Bedstead is not satisfactory. Bedsteads have also been proposed in which slats or bars that are not sufficiently hard or inflexible are mounted on the ends or on a flexible flexible support. These supports are, for example,
It is made of molded rubber and may also constrain the ends of each slat to a fixed bedstead structure. In another case, the flexible support is composed of a tube of elastic material filled with a liquid of suitable density such that the weight of the person lying on the bedstead will crush the tube most corresponding to the most stressed slats. The tubing corresponding to the unloaded slats remains slightly bulged or even "bulged" when crushed.

In another case, said flexible support at the end of the slat comprises a structural member made of elastically deformable plastic or a combination of deformable plastic structural member and a liquid-filled tube, which is bedsteaded. It has a longer response time to stresses created by the human body lying on the floor or due to relatively sudden movements, and thus the “vibration” phenomenon caused by the bidirectional movement of the liquid in the tube is minimal. While decreasing.
These bedsteads have good longitudinal fit, but poor lateral fit.

Thus, for example, the fact that the slats are not sufficiently rigid or elastic will allow the bed frame to fit transversely to the user's body due to the bowed deformation. A very thick mattress is needed to prevent this and to make the bed comfortable. The very thick mattresses used in such structures result in poor ventilation of the Bedstead. Another Bedstead related to the present invention, which differs from the slat type described above, has a rigid frame and a plurality of flexible bands or cables constrained end to said frame.

This bedstead is essentially different from the slat type and has improved lateral compatibility, but has the same disadvantages as the slatted bedstead with respect to the frame.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to use one bedstead advantage and another in order to obtain excellent longitudinal and lateral compatibility using thinner mattresses. By combining the advantages of, the above-mentioned Bedsteads, in particular the Bedstead disadvantages of orthopedic beds, are eliminated. In particular, one of the objects of the present invention is to provide a bed with slats which is perfectly adapted to various postures of the user's body while sleeping and which is excellent in ergonomics.

Another object of the present invention is to provide a slatted bedstead which is simple and inexpensive to manufacture, and which is obtained in particular from a bedstead using conventional support materials by simply changing the slat configuration. Is.

[0009]

These objects are claimed in Claim 1.
This is achieved by a Bedstead according to the invention, having the features described. The invention further relates to a slat used in a bedstead as having the features of claim 13, and an orthopedic bed made of bedstead as according to claim 16. Generally, a bedstead according to the present invention, and in particular an orthopedic bedbedstead, comprises a plurality of slats end-mounted on a resilient flexible support, each slat comprising at least one sufficiently rigid tensioning element 10 and An end is constrained to the end of the tensioning element and comprises at least one flexible elastic element under fixed tension.

For convenience, the tensioning element has a curved shape with its concave surface facing upwards, ie towards the at least one flexible elastic element pretensioned by the tensioning element. The tension elements can be made from wood, curved veneer plywood, thermoplastic moldings, one or more steel rods, steel sheets, or the like, while the flexible elastic elements have some elasticity. Very durable, for example, nylon (registered trademark)
Polyamide resin such as, aramid resin such as Kevlar (registered trademark), fluororesin such as Teflon (registered trademark),
Only have belts or cables made of cellulosic fibers such as rayon, or the like.

The elastic extension support may be a molded rubber support that constrains the ends of each slat to a rigid frame or a flexible flexible longitudinal member that rests the ends of the slats. The flexible longitudinal member having flexibility is (i)
A tube filled with a liquid (gel) of suitable density, (i
It may be replaced by i) an elastic deformable plastic (polyurethane / latex foam), or (iii) a combination of a liquid-filled tube and a tubular flexible plastic.

Bedsteads designed in this way produce a favorable effect. In particular, each slat according to the invention, which has a high flexibility and is mounted on a flexible support whose ends are elastic, is ergonomically adapted to the posture taken by the bed user.

It is also demonstrated that the belt 11 of the embodiment illustrated in FIGS. 6 and 7 can be secured to the tensioning element shown in FIG. 4 (steel rod) or FIG. 5 (steel plate). The slats 2 are attached to the longitudinal members 4 by elastic flexible supports.

As shown in FIG. 8, an elastic, flexible support 20 made of molded rubber is attached to the end 3 of each slat 2, said support also being attached to the longitudinal member 4. In detail, the support 20 has a large through hole 21 to allow it to flex elastically at the point of application of force, and a central groove 13 for the same purpose, which corresponds to the corresponding end of the slat 2. Two cavities 22 for accommodating the part 3
It is a rubber block having and. The support 20 can be attached to the corresponding longitudinal member 4 by a rod 23.

According to the embodiment shown in FIG. 9, the elastic flexible support on which the end 3 of the slat 2 rests consists of a structural member 120 made of elastically deformable plastic such as polyurethane or latex foam. The structural member is housed in the vertical member 4 and protrudes upward.
According to the embodiment shown in FIG. 10, the elastic flexible support extends over the entire length of the longitudinal member 4,
It consists of a tube of elastic material 220 containing a gel.

Finally, the resilient flexible support 320 shown in FIG. 11 is a combination of the plastic structural member 120 shown in FIG. 9 and the gel-filled tube 220 shown in FIG.
