Abstract

The present invention relates to a medical bed convertible to a chair or toilet seat.

Conventional medical bed has the upper plate fixed in a flat surface and the back plate is raised by turning the screw handle installed on the back of the bed, but all the uncomfortable patients or disabled people who are sitting alone or unable to see the toilet are uncomfortable. As shown in FIG. 6, as shown in FIG. 6, the underlay in which the towing nut 5 around the rod screw 6 reciprocates in accordance with the rotation direction of the electric motor 9. (1) install the left and right leg plates (14 and 15) on both sides, and install the back support (25) and the leg support (30) between the two leg plates, and the container support (22) on the center support (16). In the present invention, the chair upper plate 19 on which the container 23 is installed is fixed and the control switch 43 is installed on the left handrail 42. When the control switch 43 is pushed, the traction nut 5 is an electric motor ( 9) of rod screws (6) As the forward movement 46 rotates, the connected toe 36 lifts the leg rest 30, and the backrest 25 connected to the leg rest 30 rotates about the central axis 27 to be horizontal. Since it is lying down, it is converted into a bed shape, and when the steering switch 43 is pulled in reverse, the electric motor 9 rotates backward while the tow table 36 pulls the leg rest 30 downward so that the connected backrest 25 is connected to the center shaft. (27) is rotated upright and upright, it is converted into a chair, and can also be used as a toilet seat by opening the lid 18 installed on the chair top plate (19). Even when you're sitting alone or sitting up Has the advantage of seeing.

Description

MEDICAL BED, CONVERTIBLE TO CHAIR OR STOOL.

The present invention is to form a rectangular base butt to the traction device by the rotation of the electric motor, and then install the leg plate on the left and right sides, and install the leg support, chair top, backrest between the left and right leg plate The footrest plate can be raised and lowered by the reciprocating action of the traction device using the rotation direction and force of the motor according to the operation of the switch, and can be converted into a chair or the toilet seat by rotating the backrest horizontally or vertically about the central axis. It relates to a medical bed.

In the conventional medical bed, the back plate is raised when the top plate is horizontally fixed and the screw handle installed on the back of the bed is raised, but it is inconvenient because the incapacitated patient or the handicapped cannot sit alone or see the toilet.

Therefore, the present invention has been produced in order to solve the drawbacks of the conventional medical bed, a towing device composed of a traction nut, rod screw, pulley, electric motor in the underside of the medical bed, and the left and right legs on the side Install a leg support, toilet hole between the legs, and install a chair top and a back support on which the lid, container and container support are installed, and control the rotation direction of the motor on the railing of the leg. Pushing the control switch rotates the motor and rod screw forward, the towing nut moves forward, and pulling pulls the motor and the rod screw counter-rotating so that the towing nut moves backward. The backrest, which is connected to the leg rest by pulling, can be converted into a bed, chair or toilet seat while repeating the rotational movement horizontally or vertically about the central axis.

A rod screw (6) in which a tow nut (5) formed with a pin hole (4) is formed in the middle of the intermediate support (2) and the front support (3) across the middle of the rectangular base support (1). A bell pulley 7 is fixed to the end of the rod screw 6, and on the vertical side of the bell pulley 7, an electric motor 9 having a main pulley 8 mounted thereon is mounted on the left side 10 of the underlay 1. ) And the right side 11, the left leg plate 14 and the right leg plate 15 having the front shaft holes 12 and 12 ', the rear shaft holes 13 and 13', and the central support 16 and 16 '. ) And install a toilet seat hole 17 on the center pedestal 16 and 16 ', respectively, and fix the chair top plate 19 to which the lid 18 is attached. The container support 22 and the container 23 constituting the Chem shaft handle 21 are installed, and the back plate matrix 24 is installed in the rear shaft holes 13 and 13 '. After aligning the central shaft hole 26 of the shaped backrest 25, the central shaft 27 is inserted and coupled, and the conversion shaft hole 28 of the backrest 25 installs the leg plate mattress 29. and ' 'Coupling with the connecting shaft hole 31 of the leg rest (30) formed in the shape of the' shape and then inserting the coupling shaft (32 and 32 ') and the traction shaft holes (33 and 33') is the auxiliary connecting rod (34 and 34) ') Is aligned with the lower shaft holes 35 and 35' and the tow shaft 36 is centered to insert and pull the traction shaft 37, and the upper shaft holes 38 and 38 'have left and right leg plates. After coinciding with the front shaft holes 12 and 12 'of the 14 and 15, the front shafts 39 and 39' are inserted and coupled so that the connecting pin hole 40 of the towing table 36 is After matching the pin hole 4, the pin 41 is inserted and coupled, and the control switch 43 for forward and reverse rotation of the electric motor 9 by a well-known wiring method in the handrail 42 of the left leg plate 14. ) Is installed.

In the present invention configured as described above, pushing the control switch 43 installed on the handrail 42 pushes the electric pulley 7 and the belt 44 attached to the base 9 and the bellows 44 and the rod screw 6. While the forward rotation (46) to the forward movement (46) to the lower portion of the traction stand 45 connected to the traction nut (5) on the rod screw (6), the traction target portion (47) is connected to the traction shaft (37), so the forward movement (46) Since the leg rest 30 is pushed up horizontally while standing upright without being turned vertically, the back rest 25 connected to the leg rest 30 is laid horizontally while rotating about the central axis 27 to form a bed. . On the contrary, when the control switch 43 is pulled, the electric motor 9 rotates backward while the tow nut 5 and the lower part of the towing stand 45 are moved back 48 so that the backrest 25 connected to the leg rest 30 is centered. It is converted to the shape of a chair by standing upright while rotating in the reverse direction about the axis 27. Therefore, the retarded or disabled person lying on the bed can sit easily because the backrest 25 lifts the patient's back by the mechanical transformation of the bed without trying to sit hard. Open one lid (18) and open the toilet alone I can see it. However, when there is a guardian or caregiver, turn the Chem axis handle (21) installed under the chair top plate (19), and the height of the Chem (20) is low, so that the container 23 is easily removed and emptied, then washed and then the container stand (22). Since it can be fixed on the patient's caregiver or caregiver while away from his or her office, the handicapped person or handicapped person can sit alone and see the toilet by simply operating the control switch 43. Will have.
