Abstract

PURPOSE: To provide a chair on/from which a patient sites and stands up voluntarily without applying physical burden on the patient. CONSTITUTION: When the seat plate of a waist seat 5 is lifted by operating an operating mechanism, the seat plate provided with a hinge in front of the waist seat 5 is lifted from a horizontal position while its left part is inclined. When the left part of the seat plate is inclined in large, the function of a link mechanism is applied to a D-connecting rod 16 and an E-connecting rod 17 out of four connecting rods between a foot pole 2 and the backrest 12 on this side of the chair, and also, the same function is applied to the D-connecting rod D and an F-connecting rod 18 between the foot pole and the backrest on the other side of the chair. Therefore, the chair moves upward perpendicularly or at an angle suitable for human engineering gradually from the first angle 5-10 deg. of the backrest as the inclination of the waist seat 5 is increased. Moreover, the backrest moves the waist seat 5 forward, which pushes the patient and lets him/her rise in a natural posture by moving a shaft round bar 11 in a guide long groove 7.

Since there are two methods for attaching the connecting rod, the details will be described below. As a first method, in FIG. 3, the drawing shows an enlarged assembly sequence around the long groove (7). There is a guide long groove (7) on each side of the waist seat (5), and there are shaft round bars (11) penetrating the left and right guide long grooves (7), and the left and right backrests are provided at both ends of the shaft. (1
The backrest A position hole (13) of 2) is rotatably inserted, and as shown in the upper diagram of FIG. 3, the E communication rod (17) is arranged below the D communication rod (16) and the backrest (12 ) On the backrest position B (14) of the E connecting rod (17) with the H hole (2
0) is rotatably mounted. FIG. 4 is a relational assembly drawing, the K hole (22) of the D connecting rod (16) is located at the N column position (25) of the pedestal (2), and the L hole (23) of the E connecting rod (17) is located at the pedestal. Each of them is rotatably attached to the O pillar position (26) in (2).

In FIG. 6, the waist seat (5) is also in the horizontal position where the actuating mechanism (8) is not lifting the seat plate (6) of the waist seat (5) in the state of this figure. At this time, the angle of the backrest (12) with respect to the waist seat (5) of the backrest (12) was set to 5 to 10 degrees in terms of ergonomics. It should be noted here that the shaft round bar (11) is located at the left end of the guide long groove (7), and this position of the guide long groove (7) is changed to the Q long groove position (2
It is stored as 8).

In FIG. 8, the seat plate (6) gradually inclines in the left portion. At this time, the four connecting rods are the D connecting rod (16) and the E connecting rod (17) on the back (1
The link mechanism works between 2) and the pedestal (2), and
On the other side of the chair in the figure, the D connecting rod (16) and the F connecting rod (18) act as a link mechanism between the backrest (12) and the pedestal (2). As the inclination of the waist seat (5) increases,
The first backrest (12) angle 5-10 degrees is gradually vertical,
Or move upward at an angle suitable for ergonomics. In order to correct this angle, it is possible to make fine adjustments by changing the mounting positions of the backrest (12) and the pedestal (2) to which each connecting rod is attached.

In the process of the above-mentioned operation, the shaft round bar (11) penetrating into the guide long groove (7) of the waist seat (5) becomes larger than the guide long groove (7) as the seat plate (6) becomes stronger. The relative position is moved from the Q long groove position (28) to the R long groove position (29). This has the effect that the backrest (12) gradually pushes the back of the patient sitting in the lumbar seat (5) forward. However, the guide long groove (7) is not limited to the groove, and it is possible to associate the guide ring with a rod. Thus, the essence of the present invention is to naturally send the patient forward of the backrest.

The above description has been focused on the explanation of standing up the patient sitting on the chair. Conversely, when the patient sits on a chair from the standing position, the backrest (12)
When leaning back and then actuating the actuating mechanism (8) in a lowered state, the angle of the waist seat (5) gradually changes from a slope to a flat surface, and the shaft round bar (11) moves relative to the guide slot (7). It moves back from the R long groove position (29) to the Q long groove position (28), and therefore the backrest (12) also moves backward, and the inclination angles of the waist seat (5) and the backrest (12) are the original 5-1.
You can sit comfortably at 0 degree.

[Effects of the Invention] When a physically handicapped patient stands up or sits down in an ordinary chair, the patient turns his hands around the neck of the caregiver and ties his hands behind the neck, and the caregiver turns his hands on both sides of the patient. The patient was erected with his hands tied at the back. Because of that, most caregivers hurt the tibia. This invention is one operation,
The waist (5) is raised diagonally and at the same time the backrest (1
2) also vertical or in a form suitable for the patient to stand up, or
Raised to an arbitrary angle, and further, the backrest (12) moves forward on the waist seat (5) to push the patient upright and stand upright. On the other hand, when seated, the opposite effect is exerted, and the three effects act simultaneously, facilitating the patient to voluntarily sit on the chair and stand up without imposing a physical burden on the patient. Further, by using it for a seat or a wheelchair of an automobile, it contributes to the movement from the wheelchair to the automobile, which expands the action range of the patient and contributes to the health.

1. The lower part of FIG. 1 has guide long grooves (7) on both sides of the waist seat (5). In FIGS. 2, 3 and 4, the shaft round bar (11) penetrates the guide long groove (7). The backrest A position (13) of the backrest (12) is rotatably inserted into the shaft round bar (11). Further, the G hole (19) of the D connecting rod (16) is rotationally inserted into the shaft round bar (11), and the other end K hole (22) of the D connecting rod (16) is the N pillar of the pedestal (2). Install in position (25). As shown in the lower diagram of FIG. 3 and FIG.
The F connecting rod (18) is arranged above the D connecting rod (16), the J hole (21) of the F connecting rod (18) is provided at the backrest position C (15) of the backrest (12), and the other end M is formed. The hole (24) is rotatably attached to the P pillar position (27) of the pedestal (2). When the operating mechanism (8) works, the hinge (3) is attached to the waist seat (5).
The seat plate (6) having a tilt is lifted up on the left side of the drawing. At this time, the four connecting rods attached to the left and right sides of the chair are the link mechanism between the pedestal (2) and the backrest (12) of the D connecting rod (16) and the F connecting rod (18) shown in FIG. To work. If the inclination of the waist seat (5) increases, the backrest (12) moves upward from the initial angle of 5 to 10 degrees at an angle close to vertical. At this time, the shaft round bar (11) moves from the Q long groove position (28) to the R long groove position (29) in the guide long groove (7),
The backrest (12) is pushed forward, allowing the patient in the lumbar seat (5) to stand up naturally. However, the guide long groove (7) is not limited to the groove, and it is possible to associate the guide ring with a rod.
As described above, the chair structure according to the present invention in which the waist and the back are lifted and the back is moved forward.
