Abstract

PROBLEM TO BE SOLVED: To enable easy transfer of a person to be nursed between a bed or the like without need for holding and raising the person to be nursed, by providing a plurality of wheels, a backrest, a frame for connecting the wheels, a height adjusting means for adjusting a seating surface in height and a horizontal moving means for moving the sealing surface outside between the plurality of the wheels. SOLUTION: In taking a bath, a moving device is stopped by contacting to a bathtub 101, after the wheels are locked, the height of a seating surface is made to be the same as the height of an edge of the bathtub 101. Then, a pull-end 71 of an inner slide 51 is pulled out in a transverse direction to be put on the edge. In this case, since the distance between the bathtub 101 and the moving device can be shortened, a center slide is not required to be pulled out. Next, a seat 54 on which the person to be nursed sits is moved in the transverse direction by being moved across on a slide 50 which extends to the bathtub 101, and is brought close to the edge until coming to contact. Since an ordinary lift 102 is provided in the bathtub 101 to help bathing, a nursing person can easily transfer the person to be nursed to the lift 102 only by shifting the body of the person to be nursed a little. After that, the lift 102 is lifted downward and the person nursed can take a bath.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving device in which a care receiver can easily transfer a cared person.

[0002] Conventional moving devices include, for example, a hand wheelchair and an electric assist wheelchair, and various types of lifts for moving indoors by suspending and moving a cared person around a net.

[0003]

However, in a conventional moving device such as a lift or a wheelchair, the caregiver needs to hold the care receiver when transferring from the bed to the moving device. In addition, for example, when transferring from a wheelchair to a passenger car, especially when transferring to a one-box car, the caregiver needs to hold the cared person high because the seat of the one-box car is at a high position from the ground and away from the door. Was. There was a problem that this required a lot of labor. Also, in order to facilitate the transfer, the transfer method with the armrests tilted down is effective only when the distance and height between the wheelchair and the transfer target are constant, so many transfers with different distances and heights from the wheelchair There was a problem that it could not be applied to the target.

An object of the present invention is to solve the above-described problems of the conventional mobile device and to provide a mobile device that does not require a caregiver to hold a care receiver.

[0005]

Means for Solving the Problems According to the present invention, a plurality of wheels and a backrest, a frame connected to the wheels, height adjusting means for changing a seat height, and an outer surface between the plurality of wheels. The above-mentioned problem of the conventional device is solved by providing a horizontal moving means for moving the moving object.

[0006]

According to the structure of the first aspect, the caregiver pushes the moving device to transfer the next object, for example, when placed next to the passenger car, the cared person can sit on the seat and touch the seat of the passenger car while sitting at the same height. Since the vehicle can be brought close to the position, the vehicle can be easily transferred by sliding the body to the seat of the passenger car in contact with the seat. According to the configuration of claim 2, since the tip of the telescopic means can be passed to the transfer target, there is no need for a tool for supporting the distal end of the telescopic means, and even if the seat moves along the telescopic means, the moving device does not tilt. It is possible for the caregiver to make a transfer that requires little effort.
According to the configuration of claim 3, when the distal end of the expansion / contraction means is not on the transfer target, the movement of the seat can be prevented, so that the caregiver can avoid falling due to careless movement of the seat. According to the configuration of the fourth aspect, since the system is used as an armrest seat movement preventing body, the system can have a simple configuration.

[0007]

EXAMPLES Examples will be described below. FIG. 1 shows an example of a conventional mechanism for adjusting a seat height of a wheelchair.
0572. FIG. 2 shows an example of a conventional wheelchair disclosed in Japanese Patent Application Laid-Open No. 5-184624. The armrests 21 and 23 can be defeated. For this reason, when transferring to a bed, for example, the armrest 21 can be tilted outward, the body can be shifted from the seating surface of the wheelchair, placed on the armrest 21, and further shifted to the bed. ing.

FIG. 3 shows an embodiment of the present invention. In addition to the height adjustment mechanism of the seat surface, a movement mechanism is provided that can move the seat by extending the seat in a direction (lateral direction) perpendicular to the traveling direction of the movement device. It is of a drawer type using a normal linear slide 40 as shown in FIG. 4 as an expansion and contraction means, and when a caregiver or the like releases a lock described later, the drawer can be pulled out in the lateral direction. FIG. 4A shows a cross section. Linear slide 4
Reference numeral 0 indicates that the inner member 41, the center member 42, and the outer member 43 are formed via balls 44 and 45, respectively. FIG. 4B shows a state where the inner member 41, the center member 42, and the outer member 43 are pulled out. The balls 44, 45 are held by a retainer. For this reason, each member can make a smooth linear motion mutually. As shown in FIG. 5, the seat 54 has wheels 55 and is mounted on an inner slide 51 attached to the inner member 41. The center slide 52 is integrated with the center member 42. The outer member 43 is integrated with the outer slide 53 and is fixed to the seat frame 56. The slide 50 is pulled out at right angles to the plane of FIG. 5 and the seat can move on it. The moving device should be stopped as close as possible to the next one to be transferred, and after fixing the wheels with the usual wheel fixing device,
Adjust the seat height to the height of the next transfer. When the caregiver turns the handle 61 as shown in FIG. 6, the worm provided at the tip of the handle 61 rotates the worm wheel 63 provided on the shaft 62 so that the shaft 62 rotates. Bevel gears 6 provided at both ends of the shaft 62
4 causes the shaft 65 to rotate. Shaft 65 and nut 66
And a ball screw structure including a ball placed in a ball groove provided on the shaft 65. Therefore, the shaft 65
The nut portion 66 moves up and down smoothly with the rotation of.
Since the nut portion 66 is connected to the seat frame 56, the seat frame 56 can be moved up and down by turning the handle 61. Next, as shown in FIG. 7, when the drawing end 71 of the inner slide 51 under the seat is pulled out in the lateral direction, the inner slide 51 and then the center slide 52 are pulled out.
Is pulled out, and the drawn-out end 71 can be placed on a target to be transferred next, for example, a seat of a passenger car. Seat 54
Has a structure in which the flip-up type armrest portion 72 serves as a movement preventing body and cannot move unless the armrest portion 72 is flipped up. As shown in FIG. 8, the structure for fixing the armrest 72 to the seat frame is such that the fixing device 80 mainly includes a spring 81 provided in a cylindrical tube at an end portion 84 of the armrest 72, and a spring 81 provided in the cylinder. Pin 82 moving inside
When the caregiver pulls the pin 82 to the left in the figure, the end 84 of the armrest 72 can be removed from the seat frame side fixing portion 83.

FIG. 9 shows an example of transfer to a rear seat 92 of a one-box vehicle 91. The caregiver slides the seat 54 on which the cared person rides up to the rear seat 92.
Can be moved laterally across the top of the vehicle and brought close to contact with the rear seat 92. Therefore, it is possible to easily transfer the cared person to the rear seat 92 simply by slightly shifting the cared person's body to the side. Also, since the drawer end 71 can be extended long and one end can be placed on the rear seat,
During transfer, the seat of the moving device is not cantilevered but can be supported at both ends of the slide 50, so that the seat is stable and does not tilt due to the weight shift of the care receiver. Slide 50
As described above, since a plurality of stages can be extended for a long time by using a plurality of stages, the present invention can be sufficiently applied to a case where there is a seat behind a step like a one-box vehicle. Further, as described above, instead of one set of slides 50, two sets of slides 50 may be combined and extended to both the left and right sides of the moving device. In the above embodiment, the transfer to the passenger car has been described. However, the transfer from the moving device to the bathtub can be similarly performed. FIG. 10 shows a case of taking a bath. After stopping the moving device in contact with the bathtub 101 and fixing the wheels, the height of the seating surface is adjusted to the height of the edge of the bathtub 101, and the drawing end 71 of the inner slide 51 is pulled out in the lateral direction, as shown in FIG. The drawer end 71 is put on the edge of the bathtub 101. In this case, since the distance between the bathtub 101 and the moving device can be reduced, the center slide 52 does not need to be pulled out. Next, the caregiver flips up the armrest, and then places the seat 54 on which the cared person is on.
Is moved laterally over the slide 50 extending to the bathtub, and is brought close to contact with the edge of the bathtub 101. A normal elevating table 102 is installed in the bathtub to assist bathing. The elevating table 102 may be one that is mechanically moved up and down by turning a handle, or one that is moved up and down by supplying and exhausting air to and from an air bag. The caregiver can easily transfer the carousel to the elevating table 102 only by slightly shifting the body of the cared person. Thereafter, the elevating table 102 can be lowered to bathe the care receiver.

FIG. 11 shows another embodiment of the expansion / contraction means. A plurality of superimposed pipes 111, 112, 113 are provided, and the leading end 71 is connected to the innermost pipe. Normal dropout prevention is provided, and the three pipes are pulled out by pulling out the drawer end 71. Although not shown, a horizontally long roll is attached to the seat instead of the wheel, and can roll on the pipes 111, 112, and 113 and move in the direction of the drawer end 71. A groove-shaped guide is attached below the center of the seat.
To guide 12 the seat moves parallel to the pipe. The pipe may have a circular or rectangular cross section. In addition, as shown in FIG. 12 (a), an armrest 121 provided rotatably so as to be capable of being turned over may be used by attaching a plate 122 folded by a hinge 123. The hinge 123 has a structure in which the plate 122 does not spread beyond the horizontal level in the illustrated state. In this system, the distance between the transfer device and the transfer target is limited as compared with the above-described embodiment, but it can be used in a wider range than the conventional example shown in FIG. Further, FIG. 12B shows a movement prevention member 124 for the seat. The movement inhibiting member 124 is constituted by a solenoid. FIG. 13 shows an example in which the fixture 80 is electrically driven by using a solenoid 131. FIG. 14 is a block diagram showing an example in which a contact sensor is provided below the drawer end 71. Below the drawer end 71, a sensor 141 is provided for detecting that the vehicle is surely riding on an object to be transferred next. The sensor 141 may be a pressure sensor or a normal contact sensor. The fixture 80 is operated not by a manual operation but by a solenoid 131. Therefore,
In this case, the fixing device 80 can also serve as the movement preventing body locking means together with the fixing means of the armrest portion. Sensor 141
The flip-up armrest 72 is fixed to the seat frame 56 because the solenoid 131 does not pull the pin to the left until the contact is detected, so that the seat 54 cannot be pulled out. When the sensor 141 detects the contact, the determination circuit 142 sends a signal to the solenoid drive circuit 143 to pull the solenoid 131 to the left in the figure against the spring 81. Therefore, for the first time, the armrest can be flipped up and the seat can be moved. Therefore, when the drawer end is not on the next transfer target, the seat cannot be moved, thereby preventing accidental overturn. In addition to the above description, a leg that can freely expand and contract or be detachable may be provided below the drawer end to support both ends of the slide by the leg. Further, the drawer end 71 may be made freely detachable so that the seat body can pass through the slide and can be transferred to the next transfer.

FIG. 15 shows an auxiliary wheel mechanism provided to make the moving means more stable when the seat height is increased. The auxiliary wheel 151 is connected to a shaft 153 that slides in a cylinder 152 fixed to the moving device frame. A bearing may be used to enhance the sliding property between the cylinder and the shaft. A pin 154 is fitted on the other end of the shaft, and the pin 154 moves in a hole 156 of the guide plate 155. The guide plate 155 is integral with the lever 157, and the lever 157 has a fulcrum 158 fixed to the moving device frame. The upper end 159 of the lever 157 is rotatably fixed to the seat frame. In FIG. 15, the right side of the mobile device in the figure indicates the front, and the left side indicates the rear. When the seat is highest, as shown in FIG. 15A, the shaft 153 is pushed by the guide plate 155 and pushed to the left in the figure, so that the auxiliary wheels 151 reach the position where they protrude further backward from the moving device frame.
Grows. Next, as shown in FIG. 15 (b), as the seat gradually lowers, the guide plate 155 moves the shaft 153 to the right, ie, forward in the drawing, and pulls in the auxiliary wheels. Even if the seat is further lowered, as shown in FIG.
The shaft does not move any further due to the shape of 56. Note that the auxiliary wheel 151 is set at a position slightly raised as compared with the other wheels, and does not normally touch the ground. For this reason, the force which resists the movement of the auxiliary wheel 151 does not work.
