DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheelchair storage bed that can be used by an elderly or sick person who needs nursing care and can store a wheelchair inside.

[0002]

2. Description of the Related Art Various types of nursing beds for nursing the elderly or sick have been proposed. The present applicant has also proposed a wheelchair storage type bed in Japanese Utility Model Registration Application No. 0162162 in 1994.

[0003]

In the wheelchair storage type bed of the present applicant, as shown in FIG. 4 (c), the backrest 62 of the wheelchair 6 is placed in the wheelchair storage section 51 of the torso floor 5.
And the armrests 63 are stored on both sides thereof in a state where they are flush with each other. Therefore, the shape of the wheelchair storage portion 51 is formed to have substantially the same shape as the contour of the wheelchair 6 in the stored state. Therefore, when storing the wheelchair 6, the backrest 62 of the wheelchair 6 is first raised as shown in FIG. 4 (a), and the wheelchair 6 is securely adjusted to a position where the seat portion 61 enters the entrance 51a of the wheelchair storage portion 51. After that, as shown in FIG. 4B, it was necessary to push the wheelchair 6 straight in the direction of introduction, and to introduce the wheelchair 6 into the wheelchair storage unit 51. Therefore, if the seat portion 61 cannot be aligned with the entrance 51a of the wheelchair storage portion 51, or if the introduction angle is shifted during the introduction operation, an impact may be applied to the wheelchair 6 or the introduction operation may not be performed smoothly. This is repeated many times, so that the caregiver has to uselessly work, and the cared person in the wheelchair has to suffer.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a wheelchair storage-type bed in which a wheelchair can be easily introduced into a wheelchair storage section of a bed.

[0004]

Therefore, according to the present invention, a bed body, a wheelchair storage portion provided substantially at the center of the floor of the bed body, and a backrest are provided so as to be able to be tilted to the same level as the seating portion. A wheelchair-type bed comprising a wheelchair, and one end of the wheelchair storage portion being releasably provided as a wheelchair introduction opening, and a backrest in the wheelchair storage portion being substantially flush with a seating portion. In this case, an inclined surface is provided from a front end wall on both sides of the wheelchair introduction opening of the bed body to each inner wall thereof.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a state in which a wheelchair is pulled out from a wheelchair storage type bed according to the present invention, FIG. 2 is a plan view showing a state where a wheelchair is removed from the wheelchair storage type bed according to the present invention, and FIG. FIG. 4 is a plan view showing a procedure for introducing a wheelchair to such a wheelchair storage bed, and FIG. 4 is a plan view showing a procedure for introducing a wheelchair to a conventional wheelchair storage bed.

As shown in FIG. 1, the wheelchair storage type bed of the present embodiment is provided so as to be separable into a torso floor 1 having a wheelchair storage 2 and a horizontally movable leg floor 3. The wheelchair 4 is provided in the section 2. A caster 31a is provided on each of the lower legs 31 of the leg floor portion 3, and the wheelchair storage portion 2 of the trunk floor portion 1 is opened by horizontally moving the leg floor portion 3. Wheelchair 4
The backrest 42 is leveled with the seat 41 by tilting the backrest 42 horizontally, and the armrests 43 on both sides of the seat 41 are provided so that the upper surface thereof is flush with the seat 41 by pressing down. ing. As shown in FIG. 2, the wheelchair storage unit 2 includes a backrest storage unit 2b on the head side and a seat storage unit 2a on the leg side, and the seat storage unit 2a is an armrest 4 of the wheelchair 4.
3 is wider than the backrest storage section 2b by the width that stores the third storage section 3.

As shown in FIGS. 1 and 2, the torso floor 1 is inclined from the tip walls 11a, 11a facing the leg floor 3 toward the inner walls 21a, 21b on both sides of the seat housing 2a. Surfaces 10a and 10b are provided respectively. Also,
Inclined surfaces 22a and 22b are also provided at boundaries between the inner walls 21a and 21b on both sides of the seat storage section 2a and the inner walls 23a and 23b on both sides of the backrest storage section 2b.

Next, the operation of this embodiment will be described.
As shown in FIG. 3A, the wheelchair 4 is introduced slightly obliquely to the longitudinal direction of the wheelchair storage 2. At this time, the seat storage portion 2a is provided with the inclined surfaces 10a and 10b, so that the frontage thereof is widened, so that the wheelchair 4 can be easily introduced. Further, when the wheelchair 4 is further pushed into the interior of the seat storage portion 2a, the corner thereof comes into contact with the inclined surface 22a having a narrow frontage. This inclined surface 22
a is provided, the wheelchair 4 is further pushed in, so that the corner of the wheelchair 4 that has been in contact moves along the inclined surface 22a, and as a result, as shown in FIG. The introduction angle changes smoothly, and the backrest 42 is introduced into the backrest storage section 2b. At this time, when the armrest 43 is lowered, the width of the
0b, it is easy to come into contact with the wheelchair 4b, but since the inclined surface 10b is inclined, the penetration angle of the wheelchair 4 changes only by pushing it lightly, and the entire wheelchair 4 smoothly moves as shown in FIG. Is stored in. The operation of the above embodiment has been described in a state in which the backrest 42 is tilted in order to make the movement of the wheelchair 4 easy to understand, but the care receiver is actually put on the wheelchair 4 and introduced in a state in which the backrest 42 is raised. Can obtain the same effect.

[0009]

According to the present invention, the configuration is as described above.
When storing a wheelchair in the wheelchair compartment, the wheelchair can be easily introduced simply by roughly adjusting the angle without accurately aligning the wheelchair with the direction of the compartment. It has an excellent effect of not giving pain to the caregiver.
