2. Description of the Related Art The above embodiment is based on German publication No. 1260
It is known from Fig. 1 of 092. In this publication, the support piece is movably supported in a vertically extending groove in the frame. The center of each support piece is rigidly connected to a piston mounted on a roll-type velor. A shell extending from the head of the recumbent face to the foot is provided with the above-mentioned roll-shaped bellows in which a casing for containing a medium is securely sealed.
Are closely arranged. An incompressible medium such as water is sealed in the shell, and the branch pipe is
Since a container filled with a compressible medium, for example air, is connected, the elasticity of the recumbent surface is obtained within certain limits. A foamed plastic piece is stretched on the upper surface of the support piece, and the foamed plastic piece covers the entire recumbent surface without a gap and is moved up and down together with the support piece.

In another embodiment disclosed in the official gazette, each support piece is provided with two bellows, and the bellows are attached near the ends of each support piece. The voids in all bellows are connected to each other via pipes,
A pressure control valve is connected to this hydraulic device. The bell is rounded and has a diameter somewhat wider than the width of the support piece.

Further, in the above-mentioned publication, since the piston is formed so as to have various diameters and therefore various operating surfaces, for example, the support piece of the foot portion to which a slight gravity is applied during use receives an excessive load. Instead, it has been pointed out that it can be supported by a piston with a small working surface.

German Laid-Open Publication No. 2832584 discloses that
A recumbent surface is disclosed which is composed of a number of laterally installed grid elements. The grid element supported by the pressure medium common to all grid elements, in the area supporting the hips,
A flexible support element, namely a mechanical spring or an air spring, is arranged parallel to the pressure medium support means supporting the area.

W089 / 01749 discloses a slatted lath, which has a piston piston for better adjusting the distribution of weight at the end of the lath in the region of the longitudinal frame. A vertical frame portion is supported by the cylinder device. The hydraulically or pneumatically actuated spaces of the piston-cylinder arrangement overlap to form a combined hydraulic or pneumatic pressure.

In European Patent Publication No. 0354271, the laths are held by flexible means in respective laths by means of a joint, which means the Kugel.

SUMMARY OF THE INVENTION It is an object of the invention to provide a form of sluice having support pieces which are individually supported, arranged transverse to the recumbent surface and which together form a mounting surface, for example for a mattress. A floor plate for a bed frame, each supporting piece being placed in the center of only one lifting element,
On the placement surface that does not receive a load, the height of each support piece 1 is in a state where the mass of the support piece 1 and the reaction force corresponding to the mass are in equilibrium, and each support piece is in the equilibrium position in the guide means. Can be moved vertically upwards or downwards, and all lifting elements are positively coupled to one another via a kinematic coupling, so that only one support piece is loaded and x When descending from the balancer by a distance of, all other supports rise from their equilibrium position, and if the dimensions of all lifting elements are the same, the sum of the values of all the drops of the other supports is: A floorboard configured to have a value that substantially corresponds to the value of the distance x is to improve its suitability under load.

[0009]

[Means for Solving the Problems]

A) The elevating element of each support piece is a self-standing upright bellows, and the air accommodating portion of the bellows is formed in rigidity in the horizontal direction so that only the height can be changed.
And that the effective length of the support piece is formed to be proportional to the distributed load,

B) The kinematic coupling is constituted by a pneumatic coupling which connects all lifting elements to each other, said coupling having an air distributor incorporating a braking device, all bellows being provided with an air supply. Connected to the air distributor via c), each support piece is mounted via a support piece support directly to a bell provided in association with the support piece, the bellows being The support piece support portion is formed to have a width narrower than that of the support piece support portion. D) Each support piece support portion is guided by the forced guide means for ensuring the parallel movement of the support piece support portion.

[0012]

Action and effect The kinematic coupling of the individual lifting elements can in principle be produced in many ways, for example mechanically, hydraulically, pneumatically, magnetically / electromagnetically. However, according to the invention, in adjusting the height of the individual support pieces, a large static force is not required for that,
A pneumatic kinematic coupling is used.

Since the bellows provided in the present invention do not require any guide means arranged outside for adjusting the height of the bellows, the height of the support piece is adjusted to that extent. Sometimes it does not cause significant friction. In order for the height of the expansion body to change only when the volume of the expansion body changes, the expansion body must not, for example, bulge laterally. In the above pneumatic type motion coupling, the reaction force that balances with the force applied from the support piece in order to maintain the height of the support piece in a stable manner is effective for the air pressure of the connected lifting device and the effective movement of the lifting element. It is the reaction force of the strength obtained by multiplying the horizontal cross-sectional area. With this configuration, the braking force is smaller than infinity. The rise height of the individual support elements is technically unlimited. However, in order to reduce the force generated by the vertical movement load supported by the support element and thus the inertial mass, it is preferable that each support piece is formed to be light and have sufficient rigidity. The support piece itself may basically be designed with elasticity. This is because the support piece itself operates in the static state in the same manner as the above-mentioned motion coupling principle. However, in any case, the supporting member for supporting the supporting piece must be formed with rigidity.

In order to adapt the support piece to the distribution of body weight when the human body is lying down, in the present invention, the effective length of the expansion body is formed so as to be proportional to the load applied to the expansion body. Therefore, the support piece extends in the longitudinal direction to some extent over the support member of the support piece, and is supported on the bellows installed at the center. Therefore, a slight change in the height of the bells causes a relatively large change in the capacitance between the bellows.

In order to prevent the unloaded support pieces from rising abruptly when only some of the support pieces are suddenly subjected to a heavy load, the invention incorporates a braking device in the motion coupling. . This also prevents the suddenly loaded support piece from being pushed in too quickly. In that case, the braking device is preferably adjusted to suit the individual situation. It is also preferred that the expander has lateral stabilizing means to prevent the expander from expanding laterally. The floorboard of the present invention allows the floorboard to conform to the contours of the human body without the application of force or manipulation, without the use of any spring elements. The lifting element constructed according to the invention is of extremely low construction. Also provided for each support piece is a return device which, when the load is released, returns the support piece to its horizontal starting position when viewed in its longitudinal section.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a floorboard (Untermatratze) for a bed frame in the shape of a soot. The floorboard has support pieces 1 which are individually supported and arranged transversely to the recumbent surface and which together, for example, form a mounting surface for the mattress. Each support piece 1 has a vertical axis 2 of the support piece 1 from the horizontal position in cross section.
(Refer to FIG. 12) It is rotatable within a limited rotation area about a rotation shaft 3 which is provided as close as possible and in parallel with the rotation shaft 3. The illustrated floorboard consists of individual support strip units 4, one of which is shown in FIGS.

The support piece unit 4 includes the support piece 1 and the support piece 1, respectively.
The support piece support 5 formed as a U-shaped bar, the lifting element 6 on which the support piece support 5 is placed, and the support piece 1 all move in parallel when the support piece 1 moves upward. Forcibly parallel guiding means. The forced parallel guide means is composed of two downwardly extending racks 7, which are formed by the two U-shaped legs of the support piece support 5 and are rotatably supported by the support piece unit 4. Cooperate with each gear 8. However, the two gears 8 are rotatably linked in opposite directions by a rope 9 which is guided so as to intersect. It can be seen from the illustrated embodiment that each support piece 1 is formed with sufficient rigidity. Therefore, when a compressive load is applied to each of the support pieces 1 by the illustrated forced parallel guide means 7, 8 and 9, the support pieces 1 are translated in the vertical direction irrespective of the position of the operating point of the support pieces 1. You can As a result, the support piece 1 does not tilt about the horizontal horizontal axis.

The lifting element 6 mounted on each support piece unit 4 is shown in detail in FIGS. In this embodiment,
The lifting element 6 has an air-filled expander 10, which has an air supply 11 on the underside. Inflatable body 1
0 is an upright bellows. The air accommodating portion of the bellow has rigidity in the horizontal direction, but is formed so as to expand and contract in the height direction. Each fold 12 of the bellows is constituted by a tube portion which is totally closed, and the tube portion is provided with an adjacent fold 12 through an air exchange passage 13 (see FIG. 8). It is in communication. Further, the expansion body 10 is provided with a lateral stabilizing means 14, which is made of, for example, a thin plate, and is sandwiched between the folds 12 and both upper and lower surfaces of the expanding body 10.

From FIG. 9, the expander 10 is shown as
It can be seen that the support piece 1 is somewhat narrower than the support piece 1 provided in relation to, and is installed substantially in the center below the support piece 1.
In that case, the effective length of the inflatable body 10 is usually formed to be shorter in a region subjected to a slight load. Comparing FIG. 9 with FIG. 1, it can be seen that the shortest inflatable body is located in the head and foot regions.

The height of each supporting piece 1 is such that the mass of the supporting piece 1 and the reaction force corresponding to the mass are in equilibrium on the mounting surface that receives no load. From this equilibrium position, the support piece 1
Is lifted to the highest position shown in FIG. 2 or lowered to the lowest position shown in FIG. In this lifting movement, all lifting elements 6 are positively connected to each other via a coupling mechanism, namely a moving coupling, which can be moved relative to each other, so that only one support piece 1 receives a load, for example x. When lowered from the equilibrium position by a distance of, all other support pieces 1 rise from the equilibrium position and all lifting elements 6
When the effective lengths of are the same, the sum of the values of all the ascents becomes a value substantially corresponding to the value x of the ascent. Support piece 1
Pneumatic kinematic coupling is shown by way of example, which is usually constituted by an air distributor, all lifting elements 6 and air supplies 11 being connected to the air distributor.

The air distributor is particularly suitable for FIGS.
In the drawing, an air distribution pipe installed in the longitudinal direction with respect to the recumbent plane and substantially in the center below the recumbent plane, that is, an air distribution pipe provided with a connecting portion 16 for the air supply section 11 of each lifting element It has a pipe 15. The air distributor incorporates a braking device that can be adjusted from the outside. The braking device is composed of an inner pipe 17 concentrically inserted into the air distribution pipe 15, the inner pipe 17 having a hole 18 formed in a connecting portion 16 of the air distribution pipe 15, and a handle 19 on the end face side. Is rotated or swung with respect to the air distribution pipe 15.
By moving the inner pipe 17 relative to the air distribution pipe 15, the degree of overlap of the throttle holes formed between the hole 18 of the inner pipe 17 and the connection portion 16 of the air distribution pipe 15 is changed. , You can adjust or change the braking strength from the outside. Even when one or a plurality of support pieces 1 are suddenly subjected to a strong load and are strongly pressed by the above-described braking device, the support pieces 1 without a load are prevented from suddenly rising.

In order to maintain a stable equilibrium of all the support pieces 1 and to adapt the support pieces 1 to the outer contour of the body that applies a load to the seat surface of the chair, the support pieces 1 are fitted with almost no force. A slight overpressure of 10 to 20 mbar is required in the pneumatically constructed device. To fill the device with compressed air, for example, the handle 19 may be provided with an injection valve.

FIG. 12 shows various embodiments of the structure of the support piece 1 and the bearing of the support piece 1. The rotating shaft 3 is the support piece 1.
When it is provided below the actual vertical axis 2 of the support piece 1
When is rotated, various inner spaces are formed between two adjacent support pieces 1 (see the three support piece units 4 on the left side in FIG. 12). Such a defect does not occur when the support piece 1 is rotatable about its vertical axis 2, that is, the fourth, fifth, and sixth support piece units 4 from the left in FIG.
Only in case of. However, this is a problem from a structural point of view. This is because the bearing in this case requires the support piece 1 having a thickness corresponding to the bearing. In order to prevent the above drawbacks and to obtain the advantages resulting from the actual rotation about the vertical axis 2, FIG.
In the six support strip units shown on the right side of the figure, two proposals for a solution are shown. The two proposals are such that the support piece 1 is composed of two parallel single pieces 1a and 1b, and the single pieces 1a and 1b are rotatable in the center between the single pieces 1a and 1b. They coincide as long as they are connected to each other via the supporting members 20 supported. In this case, the individual pieces 1a and 1b are rotatably supported by the support member 20 and thus swingably supported. In one of the two embodiments,
The individual pieces 1a and 1b are formed of round bars, but in the other embodiment, they are formed of a flat molded body.

In order to prevent a sharp difference in contour between two adjacent support pieces 1, the adjacent edges of the two support pieces 1 are connected via a connector 21 formed by a single wire. It is preferable to connect them together. In this case, stop means 22 for limiting the swing of the support piece 1 may be further provided.
