FIG. 3 shows an AA cross-sectional view of the first cylindrical slide unit 21 shown in FIG. As shown in FIG. 3, the first cylindrical slide unit 21 is formed of an outer cylinder 21a and an inner cylinder 21b that is slidably mounted on the outer cylinder 21a. Four slide mounting portions 25 with slide grooves 25a are formed in the longitudinal direction inside the outer cylinder 21a, and a slide mounting portion 26 with slide grooves 26a faces the slide mounting portion 25 on the outer side of the inner cylinder 21b. Four places are formed in the longitudinal direction, and a slider 27 is fitted in each slide groove 25a and slide groove 26a. Therefore, in the first cylindrical slide unit 21, the inner cylinder 21b can slide inside the outer cylinder 21a. Further, the second cylindrical slide unit 22 shown in FIG. 1 is similarly configured. In addition, although the slide attachment part 26 and the slide attachment part 25 were formed in four places in the longitudinal direction, it is not limited to this and can be three or five or more, and the first and second tubes The mold slide units 21 and 22 are not limited to a cylindrical shape, but may be a square or the like.
Screw holes 28 are formed in the outer cylinders 21 a and 22 a of the first and second cylindrical slide units 21 and 22. A bracket 23a for suspending the first and second cylindrical slide units 21 and 22 is attached by the screw hole 28.

FIG. 4: shows the side view when the attachment part of the hanging basket is raised with the suspension type raising / lowering apparatus of embodiment of this invention.
As shown in FIG. 4, the hanging type lifting apparatus 10 according to the embodiment of the present invention includes a first cylindrical slide installed between a fixed bracket 12 fixed to a ceiling and an attachment part 13 of a clothes rack. A unit 21 and a second cylindrical slide unit 22 are provided. The first and second cylindrical slide units 21 and 22 are provided with pins 34a of guide rollers 33a and 33b provided at the lower ends of the belt drive mechanism 30 by winding the first and second belts 38a and 38b, respectively. , 34b move inward along L-shaped slide grooves 14a, 14b formed on the side surface of the attachment part 13 of the hanging basket, and the inner cylinders 21b, 22b shown in FIG. 1 move inside the outer cylinders 21a, 22a. By sliding upward, the first and second cylindrical slide units 21 and 22 are shortened and become horizontal, and the attachment part 13 of the hanging basket is raised.

Next, the ascending / descending operation of the suspended lifting apparatus 10 according to the embodiment of the present invention will be described with reference to FIGS.
When the lowering switch 39b of the operation switch 39 is operated, as shown in FIGS. 1 and 2, the driving roller 31 rotates as shown by the arrow D and is wound around the driving roller 31. The belts 38a and 38b are rewound. Therefore, the first and second cylindrical slide units 21 and 22 are arranged along the L-shaped slide grooves 14a and 14b in which the pins 34a and 34b of the guide rollers 33a and 33b are formed on the side surface of the attachment part 13 of the laundry basket. The inner cylinders 21b and 22b slide downward in the outer cylinders 21a and 22a to become vertical, and the attachment part 13 of the clothes rack is in the ascending state.
Next, when the up / down switch 39a of the operation switch 39 is operated, as shown in FIG. 4, the drive roller 31 rotates as shown by the arrow U and is wound around the drive roller 31. The second belts 38a and 38b are wound. Therefore, as shown in FIG. 1, the first and second cylindrical slide units 21 and 22 are L-shaped slides in which the pins 34a and 34b of the guide rollers 33a and 33b are formed on the side surface of the attachment part 13 of the clothesline. While moving inward along the grooves 14a and 14b and rising, the inner cylinders 21b and 22b are slid upward inside the outer cylinders 21a and 22a and become horizontal, and the attachment part 13 of the clothesline is in an ascending state. .
As shown in FIGS. 1 and 2, conston springs 41 are attached to both ends of the attachment part 13 of the clothes rack, and the lower ends of the first and second cylindrical slide units 21 and 22 are pulled outward. Moreover, the descent of the attachment part 13 of the clothesline can be facilitated. Further, when the attachment part 13 of the hanging basket is lowered, the lower ends of the first and second cylindrical slide units 21 and 22 are held by the conston spring 41, and the first and second cylindrical slide units 21 and 22 are held. Since the side of the abutment comes into contact with the fixing portion 12a at the lower end of the fixing bracket 12, the attachment portion 13 of the laundry basket can be fixed in the horizontal direction and stabilized in the horizontal direction.
Further, when the hanging basket attaching portion 13 is lowered, the first and second cylindrical slide units 21 and 22 are vertical, so that the hanging basket attaching portion 13 can be made to be solid in the vertical direction. It can also be stabilized in the direction.

  As described above, the hanging type lifting device 10 according to the embodiment of the present invention can raise and lower the hanging basket 11 with a simple structure, and when the hanging basket mounting portion 13 is lowered, the hanging basket 11 is also moved in the horizontal direction. In addition, the laundry can be easily attached to the laundry basket 11.

FIG. 5 shows a side view of another example of the hook receiving part attached to the hanging type lifting device of the embodiment of the present invention, and FIG. 5A shows a side view of the hook type hook receiving part. FIG. 5 (b) shows a side view of the both-side clamp-type receiving part, and FIG. 5 (c) shows a side view of the both-side-type clamp receiving part using a spring.
As shown in FIG. 5 (a), the hook-type hook receiving portion 51 has a J-shaped side surface and is fixed to the hanging basket attachment portion 13 by the attachment portion 52, so that the hanging basket 11 can be attached thereto. However, since it is formed of an elastic body, when an overload is applied to the bottom of the hanging basket 11, the hanging basket 11 can be removed downward.
As shown in FIG. 5 (b), the both-side clamp-type receiving part 53 is formed by holding parts 53 a, 53 b whose lower ends face each other so as to hold and hold the clothes-drying basket 11. Although it is fixed to the attachment part 13 and the clothes basket 11 can be attached, since the sandwiching parts 53a and 53b are formed of an elastic body, when the overload is applied below the clothes basket 11, the clothes basket 11 Can be removed downward.
As shown in FIG. 5 (c), the both-side-type hook receiving portion 55 using a spring can be rotated by a pin 58, with the lower ends thereof being pulled inward by a spring 57 so as to hold and hold the hanging basket 11. It is formed by pinching portions 55a and 55b, and is fixed to the hanging basket mounting portion 13 by the mounting portion 56, and can be attached to the hanging basket 11, but the pinching portions 53a and 53b are rotatable and pulled inside each other. Therefore, when an overload is applied to the lower side of the hanging basket 11, the hanging basket 11 can be removed downward.
For this reason, the basket receiving portion of the other embodiment described above can remove the laundry basket 11 downward when a child or an object is caught or suspended on the clothes rack 11. It contributes to improvement and can also protect the device.

In the suspension type lifting device according to the embodiment of the present invention, a belt is used for the lifting mechanism, but a wire or the like can also be used.
Moreover, although the cylindrical slide units 21 and 22 are provided with a slider between the outer cylinder and the inner cylinder, a roller may be provided instead of the slider.
In addition, the cylindrical slide units 21 and 22 have an annular cross section, but may have a square shape.
In the above embodiment, the two lifting devices 10 are connected in parallel with the rotating shaft 31a rotated by the drive motor 36. However, the hanging lifting device of the present invention is It can also be used with a clothesline attached alone.
Further, in the above-described embodiment, the example in which the hanging basket 11 is attached to the attachment portion 13 has been described. However, the hanging lifting device of the present invention is not limited to the hanging basket but can be used for lifting and lowering a hanging cabinet or the like. .
