Abstract
A bedplate is disposed in a bed frame. The bedplate includes a fixed bed part, right leg-raising parts and left leg-raising parts. The fixed bed parts are secured to the bed frame. The right leg-raising parts are rotatably coupled, at one end, to one end of the fixed bed part. The left leg-raising parts are rotatably coupled, at one end, to the end of the fixed bed part. Said ends of the fixed bed part are spaced in the transverse direction of the bed frame. A bed part driving mechanism is provided on the lower surface of the bedplate. The mechanism drives one or both of the leg-raising parts of either pair, in a rising direction.
Claims12
A rising-type bed apparatus comprising:
- a bed frame;
- a bedplate which includes a fixed bed part secured to the bed frame, and a right leg-raising part and a left leg-raising part which are adjacent in a transverse direction of the bed frame, and each of which is rotatably coupled at one end thereof to the fixed bed part;
- a driving mechanism which is provided on a lower surface of the bedplate and which is configured to drive at least one of the leg-raising parts in a rising direction;
- a back-raising part including a back middle part rotatably coupled to the fixed bed part and a pair of back parts rotatably coupled to the back middle part on opposite sides of the back middle part in the transverse direction;
- a back raising mechanism which is disposed on a lower surface of the back-raising part and which is drivable to incline at least one of the pair of back parts of the back-raising part by a predetermined angle with respect to the back middle part, when the back-raising part is driven in a rising direction by the driving mechanism;
- wherein the back raising mechanism comprises:
- at least one back-raising arm drivable to be raised and lowered;
- at least one back raising roller, disposed on the back-raising arm, to drive the back middle part of the back-raising part to raise and lower the back middle part;
- and
- at least one push-up roller, disposed on the back-raising arm, to selectively incline a corresponding one of the pair of back parts of the back-raising part by the predetermined angle with respect to the back middle part when the back-raising part is driven in a rising direction by the driving mechanism.
A rising-type bed apparatus comprising:
- a bed frame;
- a bedplate which includes a fixed bed part secured to the bed frame and a back-raising part rotatably coupled to the fixed bed part, said back-raising part including a back middle part and a pair of back parts rotatably coupled to the back middle part on opposite sides of the back middle part in a transverse direction thereof;
- and
- a back raising mechanism which is disposed on a lower surface of the back-raising part and which is drivable to raise and lower the back-raising part and to incline at least one of the pair of back parts of the back-raising part by a predetermined angle with respect to the back middle part;
- wherein the back raising mechanism comprises:
- at least one back-raising arm drivable to be raised and lowered;
- at least one back raising roller which is disposed on the back-raising arm and which drives the back middle part of the back-raising part to raise and lower the back middle part;
- and
- at least one push-up roller which is disposed on the back-raising arm and which selectively inclines a corresponding one of the pair of back parts of the back-raising part by the predetermined angle with respect to the back middle part when the backraising part is raised.
