Description

  The present invention relates to a lifting and lowering device for a moving / transfer assisting lift for a person who has a physical disability and is difficult to move or transfer by himself / herself.

  Of the conventional lifts for moving and transferring support, the ceiling traveling type lift with the rail fixed to the ceiling or wall (Technical Reference 1)

  A stand-up type lift that puts a portal frame with beams that also serve as rails and rails that stand on the floor, and places it where it is needed (Technical Document 2)

  Therefore, in this technical document, a suspended person is kept in a sitting position with a sling and a hanger, moved up and down by a flexible device and a lifting mechanism, and moved laterally by wheels and rails incorporated in the lifting mechanism portion.

  The flexible device that connects the elevating mechanism and the hanger supports the tensile force but cannot bear the moment.

  The hanger becomes an obstacle when the whole body or a part of a suspended person in a supine position is hung and cared using a conventional lift for moving transfer support.

  In addition, it is difficult to lift and move a suspended person in a supine position in a substantially horizontal state because of the structure supported by the flexible device.

  The present invention is composed of left and right horizontal members arranged in the horizontal direction, and vertical members, bearing unit mounting plates, width determining materials, and fixed shaft mounting plates above and below both ends and intermediate portions of the horizontal members. A rectangular bearing support frame, a plurality of drive rollers supported by the bearing support frame, a drive shaft into which a metal fitting and a bearing unit for locking the drive roller at an arbitrary position are inserted, and the drive roller and a hanging strap. The present invention is characterized by a lifting and lowering device for a moving transfer assisting lift used for nursing care, which is composed of a driven roller to be interlocked, a fixed shaft into which a position holder and a rotation preventing metal fitting are inserted, and claims.

  According to the present invention, only the tensile force in the direction of gravity can be applied to each hanging strap by changing the position of the plurality of drive and driven roller depending on the height and state of the suspended person in the supine position.

  Furthermore, the present invention provides a lifting device for a mobile transfer support lift used for nursing care at a high position, the hanging strap hangs from the left and right of a suspended person in a supine position, It becomes only a string and the feeling of pressure disappears.

  In addition, the present invention has two hanging straps suspended from the driving and driven rollers as one set, and several sets of the suspended straps are lifted and lowered so that the suspended frame is kept in a horizontal state, and the traveling frame is maintained in that state. It is possible to run with the wheels built in.

  DETAILED DESCRIPTION OF THE INVENTION The present invention will be described with reference to the drawings showing an example of a lifting device for a mobile transfer support lift used for nursing care. FIG. 1 is an overall perspective view showing the lifting device, and the left and right sides arranged in the horizontal direction. Horizontal members 119, 120, and vertical members 121, 122, 124, 125, bearing unit mounting plates 126, 127, width determining members 131, 132, and fixed shaft mounting plates 128 above and below both ends of the horizontal members. , 129, the vertical members 123 and 125, the bearing unit mounting plate 127, the intermediate part width determining member 133, the fixed shaft mounting plate 128, and the arbitrary position in the longitudinal direction of the horizontal member are held above and below the intermediate part of the horizontal member. In order to achieve this, a rectangular bearing support frame formed by connecting the bearing unit mounting plate 127, the intermediate width determining member 133 and the lateral movement preventing plate 134 with bolts 130 and holding the horizontal members 119, 120, and this shaft A plurality of driving rollers 113 supported by the receiving and supporting frame, a driving shaft 111 into which a lock fitting 114 and a bearing unit 118 for locking the driving rollers at an arbitrary position, and the driving roller 113 and a hanging strap 137 are interlocked. The driven roller 115, the position holder 116, and a fixed shaft into which the shaft rotation prevention metal fitting 117 is inserted, and a drive device 135 is attached to the drive shaft 111.

  FIG. 6 is a diagram showing the relationship between the hanging strap and the person to be suspended. One end of each of the two hanging straps 136 and 137 is fixed to each driving roller 113, and the other hanging strap 136 on the driving roller side among the other ends. Passes through the upper side of the driving roller and between the driving shaft 111 and the horizontal member 119, and the hanging strap 137 on the driven roller 115 side passes from the lower side of the driving roller to the upper side of the driven roller between the fixed shaft 112 and the horizontal member 120. Then, the suspension member H is suspended to the left and right, and a connecting tool 138 is attached to the tip of each of the hanging straps 136, 137, and is connected to a sling 139 that passes under the suspended person.

  FIG. 9 is a side view of the lift. The rail portion of the portal frame composed of the support column 311 and the rail combined beam 312 installed perpendicularly to the floor G includes the horizontal members 119 and 120 and the traveling frame 211 shown in FIG. 7 is integrated by the beam presser 212 and the beam receivers 213 and 214 of FIG. 7, and is moved up and down by wheels 215 incorporated in the traveling frame and lifted and lowered by a moving transfer assist lift used for nursing care.
