Abstract

The present disclosure provides a standing assistance apparatus including a support part configured to support a load, a saddle part configured to accommodate a patient to allow the patient to position from sitting condition to standing condition, and a guide part coupled between the support part and the saddle part and having an adjustable length to guide the patient to stand, wherein the guide part is disposed in diagonal direction with respect to the support part to guide the patient to stand in the diagonal direction.

First claim

What is claimed is:

1. A standing assistance apparatus, comprising:
a support part configured to support a load;
a saddle part configured to accommodate a patient to allow the patient to position from sitting condition to standing condition; and
a guide part coupled between the support part and the saddle part, and having an adjustable length to guide the patient to stand,
wherein the guide part is disposed in diagonal direction with respect to the support part to guide the patient to stand in the diagonal direction.

2. The standing assistance apparatus according to claim 1 , further comprising:
a frame installed below the support part to support the support part,
wherein a knee support part is installed in the frame to support the patient's knees.

3. The standing assistance apparatus according to claim 2 , wherein the frame comprises:
a first member which is connected to bottom of the support part and extends in a direction in which the first member intersects with the support part, the first member having a received guide part therein along the direction in which the first member extends; and
a second member which is inserted into and guided by the received guide part moveably relative to the first member, and
wherein the knee support part is installed in the second member.

4. The standing assistance apparatus according to claim 3 , wherein the frame further comprises:
an elastic part which is installed within the first member, wherein the elastic part elastically deforms between the first and second members when the second member moves relative to the first member, to provide an elastic force to the knee support part;
a ratchet gear which is installed at an end of the second member and is disposed along a direction in which the second member extends; and
a stopper part which is installed in the first member to latch the ratchet gear to limit a movement of the knee support part toward the support part.

5. The standing assistance apparatus according to claim 1 , further comprising:
a driving part which is installed within the support part to generate driving power for allowing the patient to stand; and
a power transmission part which is connected between the driving part and the guide part to transmit the generated driving power to the guide part to adjust the length of the guide part.

6. The standing assistance apparatus according to claim 5 , wherein the driving part comprises:
a gas cylinder which is installed in one direction within the support part to generate the driving power; and
a gas spring which is installed in parallel with the gas cylinder within the support part to assist a generation of the driving power.

7. The standing assistance apparatus according to claim 6 , wherein a fixed block is installed at an inner periphery of the support part, and has a guide hole formed in one direction, and
the driving part further comprises a guide rod installed in parallel with the gas cylinder within the support part, and the guide rod is supplied with the driving power and guided by the guide hole together with the gas cylinder.

8. The standing assistance apparatus according to claim 5 , wherein the power transmission part comprises:
a first pulley which is connected to the driving part to move using the driving power received from the driving part;
second and third pulleys which are installed at adjacent ends of the support part and the guide part respectively; and
a wire having two ends, one end fixed to an inner side of the support part and other end fixed to the guide part, the wire being installed in the first to third pulleys to transmit the driving power generated by the driving part to the guide part through the first to third pulleys.

9. The standing assistance apparatus according to claim 1 , wherein the guide part comprises:
a case having a shaft receiving part inside and extending in the diagonal direction; and
a shaft which is inserted into the shaft receiving part moveably relative to the case.

10. The standing assistance apparatus according to claim 9 , wherein the guide part further comprises:
a boss which is installed at an outer periphery of the shaft to guide a movement of the shaft, and latch an end of the shaft to limit the movement of the shaft.

11. The standing assistance apparatus according to claim 9 , wherein two cases and two shafts are provided,
wherein a first case is coupled to the support part, and a first shaft is inserted into the first case moveably relative to the first case,
wherein a second case is disposed in parallel with the first case at an outer periphery of the first case, and a second shaft is inserted into the second case moveably relative to the second case with one end being coupled to the saddle part, and
wherein the first case has a cutout part which is cut along the diagonal direction at the outer periphery of the first case, and the second case is guided by the cutout part and makes a relative motion in the diagonal direction with respect to the first case.

12. The standing assistance apparatus according to claim 11 , wherein connecting plate is installed at ends of the first shaft and the second case to connect the first shaft and the second case each other, and the connecting plate allows the first shaft and the second case to move relative to the first case together.
