Abstract

PROBLEM TO BE SOLVED: To provide a chair which allows a handicapped or aged person to change the chair from the seating attitude to the standing or lying attitude by himself and which can liberate the person in care from damage compulsory to the neck cervical vertebra or waist intervertebral disk originating from working in a attitude. SOLUTION: A seat back 6 and waist seat plate of a functional chair are changed from the seating to the standing attitude for a patient seated. When the seat back reclines gradually from the seating attitude, a connecting rod 11 is actuated and foot rests lift at the same time, and the whole chair is turned in bed form gradually. For these different actions from the seating to the standing and lying, a waist plate pushup rod 51 and a slide shaft 8 installed on the chair are guided from the seating position to the standing or lying position. The arrangement uses only one drive source 49, and the slide shaft 8 and waist plate pushup rod 51 are related to a rod shaft metal attached to a transmission belt 28 in loop form, and the chair is changed from the seating to standing attitude and to the lying attitude by turning the belt clockwise and counterclockwise, respectively.

No. 0-112641 was improved and a new mechanism was added. As a new mechanism, a waist plate push-up rod 51, a push-up rod tip long hole 52, a push-up metal fitting 44, and a metal fitting hole 45 are added. In the earlier application, in FIGS. There is a beam 12, the upper beam 9 and the lower beam 10 are linked by the vertical beam 12,
When standing up, lift up diagonally with backrest 6,
A link mechanism is formed between the support and the support in front of the chair. This time, the vertical beam 12 was abolished, only the upper 9 of the left and right cross beams were associated with the backrest 6, and both ends of the lower 10 of the horizontal beam were the front supports 4 of the chair.
Therefore, the link mechanism was abolished. Next, in the previous application, when the seat was set up from the standing position, the rear end of the lower cross beam 10 hit the fixed position portion 4 and was seated. However, the fixed position portion 4 was abolished and the seat position was changed from the standing position to the sitting position. In this case, the upper beam 9 is stopped so as to overlap with the lower beam 10 fixed to the front column 4 and the rear column 53 fixed to the functional chair bottom plate 12. The previously filed Japanese Patent Application No. 10
Of the names described in US Pat. No. 1,12641, a part of the working tool 7 has been changed to a sliding bearing 7 and the tip 8 of the working tool has been changed to a sliding shaft 8.

状態となることである。The functional chair mechanism described in the specification of the present application, which can change from sitting to standing and from sitting to reclining through reclining, is roughly classified into a waist seat plate 43 on which the hips are placed, a backrest 6 and a foot. It becomes three of five. 2 as a feature
As shown in FIGS. 1, 2 and 3, the patient seated on the backrest 6 of the functional chair and the lumbar seat plate 43 by the action of the front axis point 2, the rear axis point 3, and the cross beam 9 from the sitting position. The transition to the standing posture means that the backrest 6 gradually falls backward from the sitting posture, and when reclining, the connecting rod 11 acts and the footrest 5 is lifted at the same time, and the whole chair gradually becomes a bed state.

And the rod bearing A39 and the rod bearing B50 are moved from the position of the rod shaft 36 on the left side of the conduction wheel D33 shown in FIG.
When the chair is guided to the conduction wheel B31 at the position of the shaft hole b14 in FIG. 23, the form of the chair rises from sitting, and the chair is guided from the position of the conduction wheel D33 of the shaft hole d16 at the seating position to the position below the position of the conduction wheel C32 of the shaft hole c15. For example, the form of the chair changes from sitting to sleeping. The guidance is performed by rotating the conduction band 28 to the left or right.

５５の突っ張りを解除する。Next, the necessity and function of the transmission wheel E34 will be described. As shown in FIG. 10, the rod shaft 36 is provided with a rod bearing A39 attached to the lower end of the sliding shaft 8 of the backrest 6 and a push-up metal fitting 44 attached to the back side of the lumbar seat plate 43. A rod bearing B50 attached to the lower end of the rod 51 is attached rotatably. Now, when the functional chair is changed from the sitting state of FIG. 22 to the sleeping state of FIG. 23, a phenomenon as shown in FIG. 12 occurs. When considering the trajectory of the folding of the conduction band 28 from the sitting position to the bed, the position of the rod shaft 36 at the sitting position is on the conduction wheel D33, and the position of the rod shaft 36 at the bed position is the conduction wheel. The two conductive wheels under C32 are joined by a conduction band 28 to form a straight line. However, the rod shaft 36 at the lower end of the waist plate push-up rod 51 draws an arc around the push-up bracket 44. The figure shows the relationship between a straight line and an arc, and a difference 54 between the straight line and the arc is formed. Without the wheel E34, the conduction band 28 would go straight, and the arc difference 54
The conduction band 28 is destroyed only by stretching. For this reason, the installation of the conduction wheel E34 causes the rod shaft 36 to move along a locus close to an arc, thereby compensating for the difference 54 between the arcs. Further, even if the conduction wheel E34 is installed, the conduction wheel D33 and the conduction wheel E34 or the conduction wheel E3
4 and the conduction wheel C32.
In order to make up for this difference, a push-up rod tip long hole 52 is provided in the waist plate push-up rod 51 shown in FIG. Then, the tension of the small arc difference 55 between the push-up fitting 44 and the rod shaft 36 is released.

In FIG. 25, the symbol of the sitting figure is as it is, the figure is drawn with a dotted line, the symbol of the standing figure is marked with (′) on the right shoulder of the symbol, and the figure is drawn with a solid line. Now,
During the movement of the conduction band 28, the rod shaft 36 is at the position of the conduction wheel D33 when seated, and moves to the position of the conduction wheel B31 when standing up. Accordingly, the backrest 6 is at 6 ', the rear shaft point 3 is at 3', the sliding shaft 8 is at 8 ', the push-up fitting 44 is at 44', the waist plate 43 is at 43 ', and the sliding bearing 7 is at. Becomes 7 ', and becomes a standing posture.
At this time, the distance between the rear shaft point 3 and the rod shaft 36 at the time of sitting and the distance between the rear shaft point 3 'and the rod shaft 36' at the time of standing are longer than standing. The difference between the lengths at which the sliding shaft 8 extends is that the sliding shaft 8 described with reference to FIGS.
The problem is solved by the relationship of inserting and removing inside.

摺動軸８が摺動軸受７に挿出入する関係である。FIG. 26 illustrates the necessity of the sliding shaft 8 and the sliding bearing 7 from the seat to the bed. In FIG. 25, the symbol of the sitting figure is as it is, the figure is drawn with a dotted line, the symbol of the standing figure is marked with (′) on the right shoulder of the symbol, and the figure is drawn with a solid line.
Now, at the time of sitting by moving the conduction band 28, the rod shaft 36
Is located at the position of the conduction wheel D33, and the position of the rod shaft 36 shifts to a position below the conduction wheel C32 in the sleeping position. Accordingly, the backrest 6 is at 6 ', the sliding shaft 8 is at 8', the waist plate push-up rod 51 is at 51 ', and the connecting rod 1 is at.
1 shifts to 11 ', the sliding bearing 7 shifts to 7', and the footrest 5 shifts to 5 '. At this time, in the distance from the rear shaft point 3 to the rod shaft 36 when seated and the distance from the rear shaft point 3 to the rod shaft 36 'when seated, the bed is longer than the seat. The difference in the length of extension of the sliding shaft 8 is the same as described above.
The sliding shaft 8 is inserted into and out of the sliding bearing 7.

It rides on the upper surface of the lower beam 10 fixed to the support 4 and the rear support 53. In order to move the conduction band 28, the conduction wheel F35 is transmitted from the motor shaft wheel A30 of the power source 49.
The rotation is transmitted to.
