Description

[Detailed explanation of the invention] (a) Industrial application field This invention is installed in a Japanese-style room of a house, and is normally used as a tatami mat in a Japanese-style room, but when necessary, it can be raised to serve as a bed. The present invention relates to the structure of a Japanese-style bed that can be raised and lowered.

(b) Prior art A conventional Japanese-style bed has a bed frame that is the same width as the bed tatami, so that your feet will not get caught when lowering it from a raised state. It was constructed in such a way that there was no gap between which one could fit one's feet.

(c) Problems that the invention aims to solve However, if the bed frame is configured to have the same size as the bed tatami, if a patient who requires home nursing is sleeping on the bed, the nurse will When holding a patient, there was a high possibility that the patient's lower back would become stiff if the patient was not able to reach the lower back and applied too much force.

In order to solve this problem, the left and right boards that make up the bed frame are moved back from the normal tatami mat 6. If the bed is lowered with the feet inserted into the recessed areas, the nurse's feet may be pinched. The problem was that it could cause injury.

The present invention eliminates these problems.

(d) Means for solving the problem The purpose of the present invention is as described above. Next, the configuration for achieving the purpose will be explained.

A lifting mechanism 3 is provided in the storage space B provided under the floor, and the bed frame placed on the lifting mechanism 3 is raised and lowered, and when storing the bed frame, the bed frame is placed in the storage space B, and the bed tatami 1 is placed in the storage space B. It is constructed to have the same height as a normal tatami mat 6, and the bed tatami 1 is divided into two parts at the center so that it can be opened upward.

Further, a bed tatami 1 which can be divided and opened is used as a lid, and a storage A is constructed inside the bed frame.

In addition, the bed frame is constituted by front and rear plates 20, 20 and left and right plates 19, 19, and the left and right plates 19, 19 are usually provided at a position retreated below the bed tatami 1 from the end of the tatami 6, so that the feet can rest on the bed frame. A stand 9 is usually provided at the same height as the tatami mat 6.

Further, foot detection sensors 21 and 22 for detecting the presence or absence of feet on the foot resting table 9 are installed on the front and rear plates 20 and 20.
It was established in

Further, handrail fittings 2 can be attached to the left and right sides of the bed tatami 1, and the handrail fittings 2 can be attached to and detached from a handrail bracket 12 in the storage A.

Furthermore, a handrail fitting storage sensor 14 is provided which makes it impossible for the elevating mechanism 3 to lower when the handrail fitting 2 is attached.

(e) Embodiment The purpose and structure of the present invention are as described above, and next, the structure for achieving the purpose will be explained.

1 and 2, a switch 23 for operating the elevating type Japanese-style bed of the present invention is provided on the wall of the Japanese-style room.

By operating the switch 23, the height of the elevating Japanese-style bed can be freely adjusted to a desired position.

When the bed tatami mat 1 is at its highest position, the foot rests 9 provided under the left and right plates 19, 19 forming the bed frame are configured so that they are in the same position as the normal tatami mat 6. It is.

The foot resting table 9 is configured such that the left and right plates 19, 19 are moved back toward the inner case to form a foot insertion recess E so that the nurse's foot C can be placed under the bed.

By putting the nurse's feet C inside in this manner, when lifting the patient's body, the nurse can insert her hips and lift the patient, and there is less risk of her lower back being strained.

However, if the bed is lowered by operating the switch 23 with the nurse's feet C placed on the foot rest table 9, the feet will be caught between the lower surfaces of the left and right plates 19, 19, so that the bed frame Front and rear plates 20, 2
Foot detection sensors 21 and 22 are provided on the inner surface of 0.

The foot detection sensors 21 and 22 are composed of photoelectric sensor devices and the like, and can detect the presence or absence of feet in a non-contact manner.

The foot rest 9 and the foot detection sensors 21, 22 are arranged symmetrically on the left and right sides of the bed.

If only the foot insertion recess E of the foot resting table 9 and the part above it protrudes to the width of the bed tatami 1, only a part of the foot can be inserted under the bed. Therefore, the left and right plates 19,1
9 is also moved back a little to provide a shin insertion space D.

However, because the shin insertion space D exists, the foot is not placed on the foot resting table 9, so the nurse hastily inserts the foot into the shin after the bed starts lowering. If the bed protrudes into the space D and descends further, the toes of the feet are usually sheared between the upper surface of the tatami 6 and the lower surface of the tatami bed 1.

In order to solve this problem, the present invention divides the bed tatami 1 into two at the center, so that when the bed tatami 1L and 1R pinch your foot, you can rise up and escape as shown in Figure 8. It is composed of

As a result, even if the toes of the feet are inserted into the shin insertion space D, the bed tatami mats 1L and 1R rise, eliminating the risk of shearing.

Also, in the position where bed tatami 1 is raised, bed tatami 1
Handrail fittings 2L, 2R are configured to be removable on the left and right sides of the tatami mat. It is made to protrude so that it can be attached.

As shown in FIG. 3, the bed tatami 1 is double-opened from the center, with the left and right ends openable, and the interior space is configured as a storage compartment A. A handrail bracket 12 for the handrail fitting 2 is also provided in the storage A.

Furthermore, even when the handrail fitting 2 is removed, the handrail fitting 2 is configured to be stored in the storage A.

The link mechanism for rotating and opening the bed tatami 1 is disclosed in detail in FIG. A fixed link 13 is also fixed to the lower surface of , 1R, and a rotating link 1
A short link 18 and a long link 16 are interposed between the fixed link 7 and the fixed link 13.

A pivot shaft 18a between the short link 18 and the rotation link 17 is pivotally supported by the front and rear plates 20, 20. The pivot shafts 16a of the rotation link 17 and the long link 16 rotate up and down.

Due to this configuration, the bed tatami mats 1L and 1R have a pivot shaft 18.
Bed tatami 1 that rotates up and down centering on a and is divided into
The positions of L and 1R can be changed to the left and right by the short links 18 and long links 16.

Also, the support parts of the handrail fittings 2 attached to the left and right sides of the bed tatami mats 1L and 1R in the raised position will be explained.

A handrail bracket 12 is fixed to the inner surfaces of left and right plates 19, 19 constituting the bed frame, and a handrail metal fitting base 15 that can be protruded and retracted is provided on the handrail bracket 12. .
In the protruding state, the handrail metal fitting base 15 is configured to pass through through grooves 19a, 19b provided in the left and right plates 19, 19 and exit to the outside.

The handrail fitting storage sensor 14 is disposed at the position where the handrail fitting base 15 is rotated to the storage side, and the handrail fitting base 15 is in a protruding state.
Its role is to cut off the electrical circuit so that the bed cannot be raised or lowered.

The handrail fitting 2 is constructed so that the insertion rod 2a is fitted into the insertion tube 15a which is open and facing upward with the handrail fitting base 15 protruding.

Next, the configuration of the elevating mechanism 3 will be explained with reference to FIGS. 4, 5, 6, and 7.

The elevating mechanism 3 is composed of two sets of X-shaped links on the left and right, and one of the X-shaped links is a portion of the pivot shafts 11a and 11b, which is pivoted at the ends of the upper rail 29 and the lower rail 10. The other end of the ×-shaped link is supported by rotating rollers 8a and 8b.
It rotates while in contact with the upper rail 29 and lower rail 10 and changes its position.

A hydraulic cylinder 4 provides lifting power to the lifting mechanism 3.

When the hydraulic cylinder 4 is extended, the elevating mechanism 3 is raised, and when the hydraulic cylinder 4 is contracted, the elevating mechanism 3 is lowered.

The upper rail 29 is fixed to the lower surface of the bottom plate 5 of the storage space A, and the lower rail 10 is fixed to the lower surface of the bottom plate 5 of the storage space B.
It is fixedly installed on the upper surface of the bottom plate 7 of the.

Reference numeral 28 denotes a biasing spring that connects the upper portion of the pivot shaft 16a and the short link 18 to lighten the upward rotation of the bed tatami mats 1L and 1R.

(f) Effects of the invention Since the present invention is constructed as described above, it has the following effects.

First, an elevating mechanism 3 is provided in the storage space B provided under the floor, and the bed frame placed on the elevating mechanism 3 is raised and lowered. The bed tatami mat 1 is configured to have the same height as other regular tatami mats 6, and the bed tatami mat 1 is divided into two parts at the center so that it can be opened upward. If the foot insertion recess E is provided, even if the bed tatami 1L, 1R comes down with the foot inserted, the bed tatami 1L,
1R was able to ensure safety because it escaped upwards without shearing the legs.

Second, since the bed tatami 1 which can be divided and opened is used as a lid and the storage A is configured inside the bed frame, the handrail fittings 2 etc. can be stored in the storage A. It can also be used as a storage space, just like a normal underfloor storage room.

Thirdly, the bed frame is constituted by front and rear plates 20, 20 and left and right plates 19, 19, and the left and right plates 19, 19
is provided at a position that is set back below the bed tatami 1 from the end of the normal tatami mat 6, and the footrest 9 is provided at the same height as the normal tatami mat 6, so that a patient required for home nursing care can be placed on the bed. When waking up the patient, the nurse can insert the caregiver's foot C into the foot insertion recess E to the bottom of the bed, thereby preventing the occurrence of strained lower back etc. It is something that can be done.

Fourth, foot detection sensors 21 and 22 for detecting the presence or absence of feet on the foot resting table 9 are installed on the front and rear plates 20 and 2.
0, the nurse does not have to shear the toe of the foot by lowering the bed with the foot placed on the toe insertion recess E.

Fifth, the handrail fittings 2 can be attached to the left and right sides of the tatami bed 1, and the handrail fittings 2 can be attached and detached to the handrail brackets 12 in the storage compartment A, so that the upper surface of the bed, which is one tatami mat in size, can be attached. Since the handrail fittings 2 do not protrude in the narrowed position, a sufficient sleeping space can be secured.

Sixthly, since the sensor 14 is provided that makes it impossible to lower the lifting mechanism 3 when the handrail fitting 2 is attached, the bed can be lowered with the handrail fitting base 15 and the handrail fitting 2 protruding. We were able to prevent the damage caused by this.
