DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transferring an elderly person with a weak leg or a physically handicapped person from a wheelchair to a bed, or a mutual transfer between a wheelchair and a toilet seat, a shower chair, a sofa, a car seat, or the like. The present invention relates to a transfer device.

[0002]

2. Description of the Related Art In this type of transfer device, since the composite center of gravity in use is always located at the center of the bogie, the distance between the four wheels can be reduced.
Even if the patient 2) sits on a place where the entry into the lower part of the seat is obstructed, for example, a wide moving toilet seat or a bed whose lower part is obstructed, the body holding device is provided with casters (22). ) Was overhanged, so we were able to transfer. Conversely, in order to improve the stability when the patient moves while standing and to increase the size between the four wheels, if the c dimension from the center of the bogie to the caster is increased, c The overhang amount is reduced due to the extension of the dimensions, and the usability is deteriorated in the above-mentioned use place. For this reason, it has been unavoidable to provide a place where use is prohibited such as on “slope or uneven ground”, etc. (see FIGS. 2 and 3). Was inconvenient.

According to the third aspect, the middle of the arm bar, which is horizontally arranged and opened in an eight-shape, is supported from below by an orthogonal sliding metal fitting, and the intersections with the arm bars are inclined upwards outward. In addition, there is a method of generating a pinching force on both lower side surfaces when weight is applied. In this method, the friction coefficient between the slide fitting and the arm bar is generally large, and there is a disadvantage that the holding force becomes unstable with a slight adjustment.
Also, there is a method in which the bases of the two arm bars are held by pins which are inclined symmetrically inward with respect to the vertical line, and the body is clamped. In this example, a large force due to weight moment is applied to the bases of the arm bars. Occurs, which makes it difficult to balance the strength.

[0004]

The problem to be solved by the present invention is that by increasing the distance between the four casters, sufficient stability can be obtained on slopes and uneven grounds, and It is an object of the present invention to provide a moving transfer device capable of sufficiently transferring a patient who sits on a wide toilet seat where the wheels are prevented from moving forward or a bed or the like whose bottom is closed. Regarding claim 2, in order to transfer a handicapped person to a helper, assistance is provided by various combinations of actions, but in this case, an automatic brake which does not need to rely on a caster brake is provided, It is intended to save troublesome labor. Claim 3 relates to improvement of the armpit pinching ability. That is, when transferring, the patient's trunk is held by the stomach pad and the two arm bars, but it is important to separate the arm bar's holding ability, which is applied to a patient who has no arm at all. It is an object of the present invention to provide a holder which can hold the trunk satisfactorily without raising the arms and falling down as if hurried.

[0005]

In order to achieve the above object,
In the transfer apparatus according to the present invention, the tilting center of the main column is provided at a point (p) at y at the lower side in the vertical direction and at the point x at the patient side in the horizontal direction from the tilting center (o) of the branch column. The upper part of the transfer device including the can be tilted toward the patient. Arcs G1 to G drawn at center o
2, there is a limit to the horizontal reach distance even if the angle α is increased, but arcs G2 to G drawn at a small angle β with the center at p
By adding 3, a relatively large horizontal distance a can be obtained. (See Fig. 2) (Note) Here, G is the position of the center of gravity of the body and suffixes 1-3
Represents the position. In setting the center of gravity, the lower leg from the knee which is not involved in the movement at all while remaining on the footrest (2) is excluded. (See Fig. 3)

According to claim 2, in FIG. 4, the brake arm (23) is attached integrally with the main column (3), and the shaft p
Around the center. Therefore, when a downward force due to the weight is applied to the arm bar (12), the brake arm rotates clockwise about the axis p and presses the elastic friction body (24) against the floor to act as a brake. FIG. 5 shows an example of a brake arm indirectly connected to the main column. In this example, the brake arm is rotated at an angle larger than the tilt angle of the main column. According to the third aspect, the bases of the two arm bars are rotatably and freely connected to open and close, respectively, and are opened in a substantially horizontal eight-shape, and the middle thereof is parallel to the bars and obliquely upward toward the center of the device. Belt (1)
8) Hang it up. (See FIGS. 6 and 7)

[0007]

A description will be given of a case where a patient already standing on the apparatus is dropped on a bed or the like in the human body transfer apparatus configured as described above. The helper first puts one foot on the bedal (6) and pulls a lever (not shown) to release the lock (7). Then, when the slight angle handle (14) is pushed forward, the patient's body automatically starts rotating and descending with its weight, so that the patient is gently lowered onto the bed while balancing with the pedaling force. At this time, if the elasticity of the body is neglected, the trajectory of the human body weight and center becomes arcs G1 to G2 and G3, and the center of rotation is o between the arcs G1 and G2, and it is shown in the figure that it reaches G2. With no stopper, the pivot is prevented from pivoting by the main column, and thereafter, it becomes integral with the main column and pivots to G3, but its center is p. Next, to lift the patient sitting on the bed or the like, the helper may pull the handle while stepping on the pedal. Following the path opposite to the above, the center of gravity of G3 reaches G1, the main pillar stands upright and its base is stably supported by the axis p and the supporting axis (9), and the patient is automatically placed in a standing position. The lock is applied, and the body holding part and the main pillar are fixed to the carriage together. As a result, the reaching distance b from the standing position G1 to the sitting position G3 can be made longer than that of the U.S.A., and the distance c to the front wheel caster (22) can be made longer accordingly.

[0008] Claim 2 is an automatic brake which works before transferring the whole weight to the device, wherein the helper brings the transfer machine close to a patient sitting on a bed or the like, and places both feet of the patient on the footrest (2) in order, The arms are then placed on the arm bar. Then, since the patient leans on the arm bar, the body weight presses the elastic friction material from the main pillar through the brake arm to the floor, thereby acting as a brake. This is achieved by the completion of the preparation for running, that is, when the helper turns to a predetermined position and depresses the pedal to put the patient in an upright position. Claim 3 will be described in the following process of standing up a seated patient. The helper applies the arm bar to both sides of the patient and steps on the pedal to lift it. In the case of the present invention, the portion on which both sides of the arm bar ride is wrapped around the mandrel with a soft cushioning material.
Therefore, when the belt (18) is worn, the suspension angle θ is large, but the side pressure T acts as the body weight F is applied, and the cushioning material adapts to the body and dents, and becomes appropriately small. Once the patient is in the upright position, the trunk is stably held because the trunk is carried by the abdominal support in addition to the arm bars sandwiching both sides.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A base having casters (1) and a main pillar (3)
And a tiltable post (4) is taken out from a position substantially equivalent to the knee height of the main post, and in a human body transfer device provided with a body holder at the tip of the post, the tilt of the post is tilted. An axis p is provided at a point vertically y from the center o and at a point x on the patient side in the horizontal direction, by which the base end of the main column is connected to the bogie side, and the upper part of the transfer machine including the main column is placed on the patient side. Can be tilted. At the base opposite the axis p of the main column horizontal part, put out a tongue piece and support the shaft (9).
A stop bolt (8) is provided on the upper carriage side to limit the tilt angle β of the main column. By now releasing the lock (7), the branch is tilted clockwise and, when it reaches the angle α, its movement is blocked by a stopper, not shown here, after which the main column is centered about the axis p. Tilt by the amount β. In this embodiment, the horizontal portion of the L-shaped main pillar is housed in the bogie case.
May be provided in the upper part of the bogie. In this case, the height difference between G2 and G3 becomes larger for the same inclination angle β, but the horizontal dimension a becomes shorter. In designing, x, y and α, β may be appropriately combined.

[0010] According to claim 2, a brake arm (23) is attached to the horizontal tip of the L-shaped main column and extended to the patient side under the bogie, and an elastic friction body (24) is attached to the lower part of the tip. The main pillar tilts about the axis p, and the elastic friction body at the tip of the brake arm (23) comes into contact with the floor surface to act as a brake. At this time, the tip of the stop bolt (8) raises the tongue piece at the base of the main pole. A gap is provided in advance so as not to be pressed from above.
FIG. 5 is an example of indirectly transmitting the movement of the main pole to the brake arm (25). In this case, the movement of the main pole is amplified and transmitted to the brake arm. That is, the base of the brake arm is rotatably attached to the bogie (1) by the pin (26), and a point at a distance d from the pin is pressed from above by the horizontal extension tip of the main pillar. It is suspended from the bogie by a weak spring (27) to prevent rotation due to its own weight. In this case, the amplification factor is e / d. Claim 3 will be mainly described with reference to FIGS. In a holder for a human body, two arm bars (12) each having a hinge block (11) and a pin (13) at an end thereof are attached to an axis (10) provided parallel to the body and at an appropriate height. Each of them is freely rotatable, openable and closable, open in a substantially horizontal figure-eight shape, and applied to the side of the care recipient, with the longitudinal middle point of the arm bar parallel to the bar and near the center of the device. The belt (1) is provided from the suspension pins (16) (17)
8) Hang up through etc. The suspension pin is a suspension bracket (15)
The left and right are provided in plurals so that they can be used properly according to the size of the patient's chest circumference. Also, (18) is not limited to a belt, but may be a metal bar or the like having both ends free.

[0011]

According to the present invention, the dimension between the four wheels can be increased while leaving the overhang amount, which is an advantage of the conventional transfer device, as it is. This means, for example, that the front wheels of the transfer device can transfer a patient sitting on a blocked bed or a wide moving toilet seat, even if their movement is blocked, By improving the stability at the time, the conventional "slope,
It means that it is possible to lift the restrictions on use on "rough ground, deep carpet". Regarding claim 2, the effect will be described by the movement when trying to transfer. 1) The helper moves the device close to the patient while moving it finely back and forth and left and right. 2) Squat down on the patient's feet and place the feet that may be strung or immobile on the footrest, sometimes moving the device. 3) Stand on the side of the patient and hold each arm to the arm bar while holding down the arm bar (brake is applied). 4) The patient leans on the device while sitting on the bed, but does not move forward due to the braking effect. 5) The helper turns forward and steps on the pedal, causing the patient to stand. In this way, a brake that works properly in a timely manner has been provided, and hassle-free use has been reduced and labor has been reduced. With regard to claim 3, the arm bars of the stomach and the figure-of-eight arrangement are held in a row, and both sides are moistened. It is possible to economically provide a transfer device without any problem.
