Description

    The present invention relates to a bathing lift for elderly people and physically disabled persons who cannot bathe on their own.

    Various types of bathing lifts have been developed and commercialized in the past, but those in which equipment such as columns are permanently installed in the bathtub are preferable from the viewpoint of hygiene and failure frequency I can't say. In addition, a bathing person's moving posture at the time of bathing, that is, a type in which the bather moves from the tip of the bather toward the bathtub gives a feeling of fear to the bather.

As a well-known bathing lift developed in view of such circumstances, Japanese Laid-Open Patent Publication No. 2003-19180 discloses a mounting portion 12 for a bathing lift 14 composed of an installation portion 5, a transfer portion 10 and an intermediate portion 7. The technical contents are disclosed in which the receiving portion 15 of the separation type wheelchair 13 is mounted, and the receiving portion is moved up and down and laterally moved together with the bather to transfer the bath. Although this bathing lift certainly solves the above-mentioned problems, bathers are required to move in the opposite direction of lateral movement and elevation, and can be started after a complete stop when changing the transfer direction. Since it is required, a shock absorber at start and stop is required, and the transfer time is inevitably long. Furthermore, it requires two driving devices for lateral movement and lifting and lowering, so it cannot be said that it is economical.

In view of the above points, the present invention
(1) No equipment is installed in the bathtub.
(2) Unpositive bathing transfer.
(3) Continuous transfer with no change in direction of movement and without stopping.
It is intended to provide a bathing lift that realizes the above.

    The lift for bathing according to claim 1 of the present invention is the sprocket or timing pulley having the same number of teeth on the main body 100 housing the motor drive source 101, the shaft 112 on the base end side 111 and the shaft 114 on the free end side 113, respectively. 115 and 116, and an arm 110 having a chain or timing belt 117 wound around these sprockets or timing pulleys 115 and 116, and an inclined bar 120 suspended from the tip of the shaft 114 on the free end side 113, And a seat portion 131 of a separation-type wheelchair 130 that can be attached to the inclined bar 120, and by rotating the arm 110 by the motor drive source 101, the shaft 114 on the free end side 113 is rotated, In a lift for bathing that continuously transfers the sheet portion 131 into the bathtub B in a state of being suspended sideways, The shaft 112 on the base end side 111 of the arm 110 is installed on the main body 100 and the shaft 112 protrudes on the opposite side to the inclined bar 120 side, so that the arm 110 is moved along the main body 100 from the main body 100. Extending upward until it protrudes, the inclined bar 120 is suspended from the free end side 113 of the arm 110 via the shaft 114 so as to straddle the main body 100, and the main body 100 is suspended from the arm 110 and the inclined bar. 120, and can be accommodated in a moving space formed by the

    The bathing lift according to claim 2 is characterized in that, in the bathing lift according to claim 1, the inclination angle of the inclined bar 120 is the same as the inclination angle of the backrest 133 of the separation type wheelchair 130.

According to the above-mentioned bathing lift according to claim 1, since there is no installation of equipment in the bathtub, and continuous bathing transfer is performed in a horizontal direction, not only is it advantageous in terms of hygiene and number of failures, A comfortable bathing without fear can be expected, and at the same time, there are many advantages such as a smooth and stable bathing transfer even though the transfer time is shortened. Furthermore, since a single drive source for transfer is sufficient as a matter of course, there is a merit in terms of economy.
In addition, the inclined bar 120 is disposed across the main body 100, that is, the moving space formed by the arm 110, the shaft 114 on the free end side 113, and the inclined bar 120. Because it is housed inside, the horizontal dimension “×” (see FIG. 1) of the entire bathing lift is shortened, bathroom space can be used effectively, and transportation is performed with a single drive source. The bathing efficiency is good.

    In the bath lift according to claim 1, if the inclination angle of the inclination bar 120 is the same as the inclination angle of the backrest 133 of the separation-type wheelchair 130, the angle of the backrest 133 of the separation-type wheelchair 130 is suitable for bathing. Can be tilted to a different posture.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In the figure, reference numeral 100 denotes a main body installed at a position close to the bathtub B and containing at least a motor drive source 101 such as an electric hydraulic motor or a variable speed motor controlled by an inverter . It has a half shape. Reference numeral 110 denotes an arm formed by combining two pieces. This arm is keyed 103 on the output shaft 102 of the motor drive source 101 on the base end side 111 and is pivotally supported. Further, in the arm 110, sprockets or timing pulleys 115 and 116 having the same number of teeth are fixed to the shaft 112 on the base end side 111 and the shaft 114 on the free end side 113, respectively, and a chain is formed between both sprockets or timing pulleys. Or the timing belt 117 is wound. A shaft 114 on the free end side 113 of the arm 110 extends in a direction opposite to the output shaft 102 of the motor drive source 101 and protrudes from the arm 110, and the shaft end is rigidly connected to the inclined bar 120. The inclined bar 120 is disposed so as to straddle over the main body 100, and the rear vertical piece 121 has a seat portion 131 of a well-known separable wheelchair 130 in which the seat portion 131 and the carriage portion 132 can be separated. Any suitable gripper 122 for holding and mounting the back frame is disposed. Further, any appropriate locking tool 104 for locking the carriage portion 132 of the separation type wheelchair 130 is installed on the side surface of the lower frame 105 of the main body 100. Further, the inclination angle of the inclination bar 120 is designed to be the same as the inclination angle of the backrest 133 of the seat portion 131. The combination method of the splot and the chain or the timing pulley and the timing belt stored in the arm 110 is a technique that is widely used in industrial robot arms and the like. The output shaft of this is held in a stopped state.

    Next, the operation and use state from bathing to bathing will be described using the bathing lift configured as described above. First, the bather is placed on the separation type wheelchair 130, conveyed from the dressing room or the like into the bathroom, washed with a shower or the like, and then the backrest 133 is tilted and approached backwards toward the bathing lift. When the wheelchair 130 reaches about 50 cm in front of the main body 100, the wheelchair 130 is moved by a predetermined path by being restricted by a guide member (not shown). When the wheelchair 130 further approaches the side surface of the main body 100, the wheelchair 130 is slowly pushed in to dock both. That is, the carriage portion 132 is automatically locked by the locking tool 104 of the main body 100, and at the same time, the seat portion 131 is automatically gripped by the gripping tool 122 of the inclined bar 120. At the time of such docking, the separation-type wheelchair 130 is designed in advance so that the carriage portion 132 and the seat portion 131 can be detached.

    Next, when the motor drive source 101 is driven by the remote control switch SW, the bather is suspended by the inclined bar 120 together with the seat portion 131 by the rotational movement of the arm 110 and smoothly while drawing a combined trajectory of lateral movement and up-and-down movement. Continuously transferred. And when a bather reaches the predetermined position in the bathtub B, rotation of the arm 110 is stopped and bathing is started. Of course, since the inclined bar 120 being transferred is not subjected to the rotational force from the shaft 114, the posture of the bather does not change at all and a comfortable bathing can be expected. The bath depth can be adjusted by controlling the rotation angle of the arm, and the transfer speed, slow start, slow stop, etc. can be arbitrarily set by adopting a variable speed motor. And the bathing after bathing should just be performed by operation reverse to the above.

    As described above, the present invention not only satisfies the requirements (1), (2), and (3) described above, but also the tilt bar 120 is disposed across the main body 100, so that the horizontal dimension of the entire lift The “×” is shortened, the bathroom space can be used effectively, and the transfer is performed with a single drive source, which is economical and has good bathing efficiency.
