[Prior art]

 As a conventional technique, there is one shown in FIGS. 3 and 4. In FIG. 3, reference numeral 1 is a frame body framed in a box shape by a vertical rod 1a and a horizontal rod 1b, and wheels 2 are attached to the lower four corners. Two upper and lower shelves 3 and 4 are mounted in the frame 1. As shown in FIG. 4, each of the shelf frames 3 and 4 has two sets of support rods 3a, 3b, 4a, and 4b on the front part (left part) and the rear part (right part) at predetermined intervals in the front-rear direction. It is extended in the horizontal direction (left and right in FIG. 3), and its both ends are fixed to the crossbars 3c and 4c which are bridged between the vertical rods 1a of the frame 1. The distance L between each set (3a, 3a) of the supporting rods 3a, 3b, 4a, 4b is smaller than the diameter dimension of the ring-shaped object 6 such as a wheel to be mounted. In the figure, reference numeral 5 denotes a partition rod that is bridged between the upper and lower horizontal rods 1b and 1b of the frame body 1, and the ring rods 6 mounted in parallel on the support rods 3a, 3b, 4a and 4b.

[Problems to be solved by the device]

 In the above-mentioned conventional one, since the shelf frames 3 and 4 are fixed to the frame body 1 and the upper and lower intervals are constant, the upper and lower intervals H are set so that the annular object 6 can move in and out. When the ring object 6 is mounted between the lower support rods 4a, 4a, for example, the distance H1 between the ring object 6 and the upper shelf frame 3 increases, and the mounting efficiency of the ring object 6 decreases. was there. Moreover, since a large gap is generated between the ring-shaped object 6 mounted on the lower shelf frame 4 and the upper shelf frame 3, the ring-shaped object 6 mounted on the lower shelf frame 4 moves during transportation. It had the drawbacks of being damaged and making noise. Further, there is a drawback that various types of carriages having different vertical intervals of the shelf frames 3 and 4 are required according to the size of the ring-shaped object 6. It is an object of the present invention to obtain a new carriage for transporting an annular object, which solves the above-mentioned drawbacks.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 is a side view showing an embodiment of the present invention, and FIG. 2 is a sectional view taken along line II-II of FIG. In FIG. 1, 10 is a trolley framed by metal pipe material, and is configured as follows. That is, a rectangular parallelepiped (box) -shaped frame body 11 is formed by framing the vertical rods 11a and the horizontal rods 11b, and wheels 12 made of casters are attached to the four corners of the lower portion of the frame body 11. The upper, middle, and lower shelves 13, 14, 15 that are vertically separated from each other are attached.

The lower shelf frame 15 is integrally fixed to the lower end portion of the frame body 11 and also serves as a horizontal rod 11 b below the frame body 11. That is, as shown in FIG. 2, two sets of support rods 15a, 15a, 15b, 15b are respectively provided at the front part (left part) and the rear part (right part) horizontally at predetermined intervals in the front-rear direction (see FIG. 1). It is extendedly arranged in the (left and right) direction, and its both ends are fixed to a horizontal rod 11b which is bridged under the vertical rods 11a. The distance L before and after the supporting rods 15a, 15a and the distance L before and after the supporting rods 15b, 15b are both equal and smaller than the diameter dimension of the ring-shaped object A such as a wheel mounted on the carriage 10.

The upper shelf frame 13 and the middle shelf frame 14 both have the same structure, and the middle shelf frame 14 will be described as a representative. That is, as shown in FIG. 2, a sliding cylinder 16 is slidably fitted to each vertical rod 11a, and a ring-shaped spring bearing 17 is fixed to the vertical rod 11a located below the sliding cylinder 16. An elastic body 18 made of a coil spring is interposed between the spring receiver 17 and the lower end of the sliding cylinder 16, and the sliding cylinder 16 is elastically supported by the elastic body 18. External support rods 19 and 19 extending in the left-right direction in FIG. 1 and crossbars 21 and 21 extending in the front-rear direction (the left-right direction in FIG. 2) are fixed between the sliding cylinders 16, and the external support rods 19 and 19 are fixed. The two inner support rods 20, 20 are arranged in parallel in the front and rear direction at a predetermined interval in parallel, and both ends thereof are fixed to the crossbars 21, 21. The front-rear distance between the outer support rod 19 and the inner support rod 20 is equal to the front-rear distance L between the support rods 15a, 15a of the lower shelf frame 15 described above.

The amount of bending of the elastic body 18 with respect to the load is set as follows. That is, when the ring object A is not loaded on the upper and middle shelf frames 13 and 14, the elastic body 18 extends to move the upper and middle shelf frames 13 and 14 upward, The annular object A was mounted so that the vertical interval between the middle shelf frames 13 and 14 and the vertical interval H between the middle and lower shelf frames 14 and 15 were larger than the diameter dimension of the annular object A. At the time of loading, the elastic body 18 is shortened (compressed) to move the upper and middle shelf frames 13 and 14 downward so that the vertical distance H becomes smaller than the diameter dimension of the ring-shaped object A. To do.

Reference numeral 22 denotes a partition rod that is mounted on the support rods 15 a and 15 b of the shelf frames 13, 14 and 15 and the inner and outer support rods 19 and 20 in parallel to prevent collision between the ring-shaped objects A. It is bent in a U shape, and both ends (lower ends) thereof are erected and fixed between the support rods 15a, 15a, 15b, 15b and the inner and outer support rods 19, 20 facing each other in the front-rear direction.

A holding frame 23 having substantially the same structure as the upper and middle shelf frames 13 and 14 is attached to the upper part of the upper shelf frame 13. That is, as shown in FIG. 2, a sliding cylinder 24 is slidably fitted to each vertical rod 11a, and a spring receiver 25 is fixed to the vertical rod 11a located below the sliding cylinder 24. An elastic body 26 is interposed between the receiver 25 and the lower end of the sliding cylinder 24. External support rods 27, 27 extending in the left-right direction in FIG. 1 and cross bars 29, 29 extending in the front-rear direction (left-right direction in FIG. 2) are fixed between the sliding cylinders 24, and the external support rods 27, 27 are fixed. Two inner support rods 28, 28 are extended in parallel in the front-rear direction with a predetermined space in between, and both ends thereof are fixed to the crossbars 29, 29. The initial position of the holding frame 23 is located slightly above the diameter dimension of the annular object A with respect to the upper shelf frame 13 when there is no load.

Next, the operation and effect of the above embodiment will be described. The ring-shaped object A made of an auto-buy wheel is sequentially mounted on the lower shelf frame 15, the middle shelf frame 14, and the upper shelf frame 13. In this case, the weight of the middle shelf frame 14 increases due to the mounting of the annular body A (A2), and the elastic body 18 supporting the shelf frame 14 is compressed and moves downward. As a result, as shown in FIG. 2, the lower surfaces of the inner and outer support rods 20, 19 are pressed against the upper portion of the ring-shaped article A1 mounted on the lower shelf frame 15 to hold the ring-shaped article A1. Similarly, the weight of the upper shelf frame 13 increases due to the mounting of an annular body (not shown), and the elastic body 18 supporting the shelf frame 13 is compressed and moves downward. As a result, the lower surfaces of the inner and outer support rods 20 and 19 are pressed against the upper portion of the ring-shaped article A2 mounted on the middle shelf frame 14 to hold the ring-shaped article A2. Next, the holding frame 23 is pulled down by a rope (not shown) and moved downward, and the lower surfaces of the inner and outer support rods 28 and 27 are pressed onto the upper part of the ring-shaped object A (not shown) mounted on the upper shelf frame 15. Then, the ring product A is held. As a result, the upper and lower annular objects A mounted on the carriage 10 are held by the middle shelf frame 14, the upper shelf frame 13 and the holding frame 23, and the left and right annular objects A are It is partitioned by the partition rods 22 so that it does not move carelessly or vibrate during transportation.

Further, when the rod A is taken out from the trolley 10, it is sequentially taken out from the upper shelf frame 13 toward the middle shelf frame 14 and the lower shelf frame 15. That is, first, the rope (not shown) is loosened, and the holding frame 23 is moved upward by the reaction force of the elastic body 26 to widen the space between the upper shelf frame 13. In this state, the rod object A is taken out from the upper shelf frame 13. Then, the shelf frame 13 is moved upward by the reaction force of the elastic body 18 and the space between the shelf frame 13 and the middle shelf 14 is widened. As a result, the rod A (A2) can be taken out from the middle shelf frame 14. Further, when the rod A (A2) is taken out, the middle shelf frame 14 is moved upward by the reaction force of the elastic body 18 to widen the space between the lower shelf frame 15. As a result, the rod object A (A1) can be taken out from the lower shelf frame 15.

[0013]

[Effect of device]

 As is apparent from the above description, the present invention supports each of the second and higher shelf frames so that they can be moved up and down on the frame body through elastic bodies, and can be moved up and down by detaching and mounting the annular body. As a result, no gap is created between the loaded ring-shaped object and the shelf frame directly above it, which improves the loading efficiency of the ring-shaped object and inadvertently moves the ring-shaped object loaded during transportation. No longer vibrates. Furthermore, since the vertical spacing of each shelf frame changes according to the size of the ring object, it is possible to carry multiple types of ring objects with one type of trolley, reducing the number of types of trolleys. Play.
