Description

[Detailed description of the invention] This invention has buttons on the floor of a bed formed in a rectangular shape to place a pinerest, and has a plurality of horizontal bars that have stronger elasticity and a lower elasticity that can be changed. This invention relates to the structure of the floor of a bed consisting of an appropriate number of leaf springs.

14' The bed device has a rectangular base formed by a headboard, a footboard 3, and a pair of side plates, and a floor is provided on the upper surface of this base, and a pine mattress is placed on this floor. .

Recently, in order to improve sleeping comfort, there have been some devices that are equipped with elastic leaf springs on the entire floor, but these have the disadvantage of significantly increasing costs.

By the way, in order to improve the above drawback,
31, there is a base having a rectangular shape, and has a floor section with a bent leaf spring installed between the side plates at approximately the center in the longitudinal direction, and horizontal bars installed at other parts.

However, since the elasticity of the leaf springs is fixed on the floor of the bed constructed as described above, users who place a large load on the area of the bed may find it difficult to sleep because the marker sinks too much, or they may find it difficult to sleep near the cherry blossoms. For users with a small load, the effect of the leaf springs is not fully demonstrated, and the elasticity of the leaf springs must be selected from several types in order to provide each user with a good sleeping comfort. There is.

In addition, in the above configuration, since the floorboard is integrated, if a large load is applied to the boundary between the floorboard and the board spring, the floorboard will hardly deform, but the board will deform greatly, so there will be no large difference in level. There is also the problem that the outer fabric of the pinerest placed on the floor is likely to be damaged due to the difference in level.

The purpose of the present invention is to provide a structure for the floor of a bed that eliminates such drawbacks and inconveniences. An appropriate number of leaf springs are installed, and the elasticity of one or more of the leaf springs is variable, and a plurality of independent leaf springs with stronger elasticity are installed between the side plates near the central part. To provide a structure of a floor part of a bed which can provide good sleeping comfort according to the body of a user by constructing horizontal beams.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, the bed 1 consists of a base 2 and a floor 3 placed on the base 2.

The base body 2 includes a headboard 4. It consists of a footboard 5 and a pair of side plates 6, each of which is connected at both ends with a bracket l and bolts 8.

Reference numeral 9 denotes a beam attached to the inside of the side plate 6 of the above-mentioned illusion.

Reference numeral 10 denotes a flexible piece attached to the top of the rod 9, which has six recesses 10a (see Fig. 5) at regular intervals approximately in the center in the longitudinal direction, and six recesses 10a (see Fig. 5) at regular intervals on both sides of the recesses 10a. Large concave portions (not shown) are formed to alternate with convex portions 10b.

Next, to explain the configuration of the main part of the present invention based on the drawings, 111/i are all horizontal bars of the same thickness and stronger elasticity, and both ends of the horizontal bars are made of relatively large flexible pieces 10. It is fitted into a recess (not shown).

Reference numeral 12 indicates a plurality of leaf springs which are all of the same thickness and are curved upward in advance to have elasticity, and an appropriate number of them have steel wires 13. Hanging bracket 14° support bracket 15. Wire holder 16. The fastening fitting 1 fixed to the fastening fitting 16
7. Lever 18. It has a handle 18a, one threaded end of the steel wire 13 passes through the hook 14 and is locked with a nut 20 via a coil spring 19, and the other end is attached to a lever 18 attached to the tightening shaft 16. It is connected to one end of the body by a pin 22 via a washer 21 so as to be rotatably slidable.

Said hook fitting 14. Support bracket 15. The wire receiving fitting 16 is fixed to the leaf spring 12 with a bolt 26 and a nut 2I.

The support holder 15 has a through hole 15a for the steel wire 13, and the size of the throttle hole 15a is such that it allows the vibration of the steel wire 13 due to the operation of the lever 18.

Further, the position of the throttle hole 15a is such that the tension of the steel wire 13 is the same as that of the leaf spring 12.
The steel wire 13 is set to curve slightly downward in order to always support the center part of the frame from falling locally.

The wire receiving fitting 16 has a substantially fan shape, and has several recesses 16a on its arcuate side to which the lever 18 is to be fixed.

The connecting portion between the fastening shaft 11 and the lever 18 is connected by a pin 23 via a wave washer 24 and a washer 21, and an E-shaped tongue 25 so that the lever 1r can rotate and slide and move slightly up and down. ing.

The lever 18 has a slight spring effect, and is provided with a recess 18b for smoother vertical movement when the wire receiving fitting 16 is attached to and removed from the recess 16a.

Reference numeral 28 denotes a center wire, and the hook portions 28a at both ends of the center wire are firmly secured to substantially central portions of the pair of parallel side plates 6 via the rods 9.

Therefore, although the pair of side plates 6 are not curved outward 710, the horizontal beam 11 and the leaf spring 12 are not detached from the recesses 10a, 10b of the flexible piece 10.

According to the present invention, as on the ground, a plurality of independent horizontal beams are provided which have stronger elasticity in the floor part except for the approximately central part in the longitudinal direction of the bed, and also have a weaker elasticity in the floor part approximately in the central part. The structure uses multiple leaf springs, one of which is on a wooden platform, so that the user can easily change the elasticity. The independent horizontal bars follow the deformation of the leaf springs in response to large loads on the boundary between the horizontal bars and the leaf springs, so that the pine i-res in contact with these horizontal bars and the leaf springs is It also has an extremely excellent practical effect of preventing damage to the outer fabric.
