Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved bottom pinerest having elasticity and having a rectangular shape on which a pinetress is placed.

Conventionally, the bottom pinerest on which the pinerest is placed to form the bed has uniform elasticity and is fixed, so some users may find that if the bottom pinerest is soft, the buttocks sink too much and it is difficult to sleep, while if it is hard, the bottom pinerest may be difficult to sleep on. The drawback was that the buttocks were pushed up, making it difficult to sleep.

The present invention was developed in consideration of this drawback, and its purpose is to provide a comfortable sleeping experience by allowing the user to adjust his or her sleeping position with simple operations. By installing a leaf spring with variable elasticity that can be easily operated by the user between the side plates at approximately the longitudinal center of the bottom pine tress, it is possible to obtain a good sleeping posture according to the user's body. .

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

The bed 1 is made up of a bottom pinerest 2 and a pinerest 3, and the bottom pinerest 2 is made up of an outer structure 4 and a base 5 as shown in FIG.

The outer structure 4 is made up of a structure 6 and a lining 7 attached thereto.

The base body 5 is made up of a plurality of springs 8 and a bottom plate 9, and the springs 8 are made up of three groups as shown in FIG.
are placed on the bottom plate 9, and a plurality of staples 10...
It is fixed and integrated with...

Further, the outer structure 4 is attached to the bottom plate 9 of the base 5 from the back side with bolts 1 through brackets 11 attached to the structure 6.
It is fixed by 2.

The structure 6 has a frame 13 and supporting force variable devices 14, 14 on the left and right inner surfaces in the width direction at two locations in the lower thigh and lumbar vertebrae of a standard human body in the longitudinal direction of the frame 13. .

The supporting force variable devices 14.14 are connected to each other by a stepped shaft 20, each having a screw 22.
It is fixed to the frame 13 by.

In advance, an elasticity adjusting device 16 is provided in order to support the leaf spring 15, which is slightly curved like a sumo wrestler, at the side part. The rotation of the handle 19 is integrated, and the rotation of the handle 19 rotates the cam 18 having a slope perpendicular to the rotation axis, displacing the plate end 17a of the torsion coil spring 17, and then displacing the tip 17b of the torsion coil spring 17. configured to be displaced.

Further, as a modified embodiment of the variable support force device 14, a stepped shaft 20 is provided with a male thread 20a, and a movable body 21 (square nut) having a female thread 21b in the center as shown in FIG. The spring receiver R21a grips one end of the torsion coil spring 17, and the moving body 21 is moved (displaced) by rotating the handle 19.
By displacing the plate end 17a of the torsion coil spring 17, the tip 17b of the torsion coil spring 17 is configured to be displaced.

As a result, the plate spring 15 connected at the tip 17b of the torsion coil spring 17 is displaced.

According to such a configuration, a crank, gears, etc. can be attached to the shaft, and these can be easily made electric by driving them with a motor.

In designing such a variable support force device 14, one of the important things is to make the lowest point of the leaf spring 15 equal to the height of the base 5, and the other is to make the lowest point of the leaf spring 15 equal to the height of the base 5. The constant is set to be slightly larger than that of the base 5.

As described above, in creating a bottom pine tress with elasticity, the outer structure has a variable support force device that can be operated from either side of the outer structure at two locations approximately in the center in the longitudinal direction, and a variable support force device that can be operated from either side. Because the structure is such that the base body has elastic bodies that are divided to compensate for the rest, the user can operate the variable support force device on the bed with the pinerest on either the left or right side. All you have to do is operate the handle, and the support force can be easily and quickly changed around the lumbar region, allowing the user to obtain a sleeping position and partial body pressure that suits him/herself, and ultimately, the user can obtain the desired sleeping comfort. Moreover, compared to conventional bottom pine braces, the outer structure and the base are fixed only with bolts, so even though it has a complicated mechanism, it is easy to assemble and internal maintenance is also easy. be.
