This cart 10 is for temporarily storing and transporting articles such as semi-finished products and finished products in factories and warehouses.

  The cart 10 includes a bottom plate 11. The bottom plate 11 is a member that forms a bottom portion of the carriage 10 and serves as a base, and is formed of a resin plate-like body formed in a rectangular shape. Four support columns 12 a to 12 d are provided on the upper surface of the bottom plate 11. The struts 12 a to 12 d are resin pipe bodies having rigidity, and are provided in a state where they stand up at the four corners on the upper surface of the bottom plate 11. Horizontal reinforcing bars 13a, 13b, 14a, 14b are respectively installed between these four columns 12a-12d between the columns 12a-12d adjacent to each other.

  The horizontal reinforcing bars 13a and 13b are made of FRP (Fiber Reinforced Plastics) pipe members, and are substantially equally spaced in the vertical direction in the figure on the front surface (left side in FIG. 2) and back surface (right side in FIG. 2) of the carriage 10. Three are arranged in each. More specifically, the horizontal reinforcement bar 13a is installed between the support column 12a and the support column 12b, and connects the support column 12a and the support column 12b. The horizontal reinforcement bar 13b is installed between the support column 12c and the support column 12d. The column 12c and the column 12d are connected to each other. These horizontal reinforcing bars 13a and 13b constitute a strong frame together with the support columns 12a to 12d and the horizontal reinforcing bars 14a and 14b, and support a loading platform 20, which will be described later.

  Further, the horizontal reinforcing bars 14a and 14b are made of FRP pipe members, and three of them are arranged at substantially equal intervals in the vertical direction in the figure on the left and right side surfaces (left and right direction in FIG. 1) of the carriage 10. ing. More specifically, the horizontal reinforcing bar 14a is installed between the column 12a and the column 12c to connect the column 12a and the column 12c, and the horizontal reinforcing bar 14b is installed between the column 12b and the column 12d. Thus, the support column 12b and the support column 12d are connected. These horizontal reinforcing bars 14a and 14b constitute a strong frame together with the support columns 12a to 12d and the horizontal reinforcing bars 13a and 13b.

  A top plate 15 is provided at the upper ends of the columns 12a to 12d. The top plate 15 is a member that forms a ceiling portion of the carriage 10 and is configured by a resin plate-like body formed in a rectangular shape. Four casters 16 are provided on the bottom surface of the bottom plate 11. The casters 16 are wheels whose directions can be freely changed to freely move the carriage 10, and are provided at four corners of the bottom surface of the bottom plate 11.

  A loading platform 20 is supported on the horizontal reinforcing bars 13a and 13b. As shown in FIG. 3, the loading platform 20 includes support bars 21 a and 21 b, an article accommodation band 23, and a buffer body 24. The support rods 21a and 21b are aluminum rod-shaped members for supporting the article housing band 23, and are formed with a length slightly longer than the interval between the horizontal reinforcement rod 13a and the horizontal reinforcement rod 13b. A hook-shaped hook 22 is provided on each upper surface of each end of each of the support rods 21a and 21b. The hook 22 is a fastener for hooking the horizontal reinforcing bars 13a and 13b to support the supporting bars 21a and 21b on the horizontal reinforcing bars 13a and 13b. That is, the horizontal reinforcing bars 13a and 13b correspond to the support portion according to the present invention.

  The article accommodation band 23 is a cloth-like band-shaped member for holding the article B to be accommodated in the carriage 10, and is provided in a slack state between the support bar 21 a and the support bar 21 b. . A wall portion 23a for closing the end portion is formed at the end portion of the article containing band 23 on the side of the horizontal reinforcing bar 13b. In other words, the article storage band 23 is formed in a substantially bag shape having an open end on the upper side and the horizontal reinforcing bar 13a side (the front side of the carriage 10). The article storage band 23 is stitched in a tubular shape at both ends in the longitudinal direction of the belt-shaped cloth material (the seam is indicated by a broken line in the figure), and support bars 21a and 21b are attached to the stitched tubular portion. It is made by inserting.

  The shock absorbers 24 are respectively attached to the upper end portion of the left side surface in the figure in the article storage band 23 and the upper end portion of the right side surface in the figure in the rightmost article storage band 23 in the figure. The shock absorber 24 is a protective member for preventing an article accommodated in the article accommodation band 23 from being damaged by coming into contact with other articles or objects, and having a size corresponding to the side surface of the article accommodation band 23. It is composed of a urethane plate. The loading platform 20 configured as described above is provided so as to be hung on each of the horizontal reinforcing bars 13a and 13b provided in three stages along the vertical direction in the drawing.

(Operation of the carriage 10)
Next, the operation of the carriage 10 configured as described above will be described. First, the worker prepares a carriage 10 and an article B to be accommodated in the carriage 10. In this case, it is assumed that the article B is not accommodated in the loading platform 20 of the carriage 10, and the loading platform 20 is in a state of being brought to the left side in the drawing (the uppermost stage in FIG. 1).

  Next, the operator moves the loading platform 20 to a position where the article B is accommodated on the horizontal reinforcing bars 13a and 13b. Specifically, the worker moves the support bars 21a and 21b in the loading platform 20 to the right side in the figure. In this case, the support bars 21a and 21b move to the right side in the figure as the hooks 22 provided on the upper surfaces of both ends of the support bars 21a and 21b are displaced while sliding on the horizontal reinforcing bars 13a and 13b. Next, the worker opens the article storage band 23 in the cart 10 according to the size of the article B to be stored. Specifically, the operator slides the support bars 21a and 21b in the loading platform 20 in directions opposite to each other (in a direction away from each other). Thereby, the upper part of the article accommodating band 23 and the end part on the horizontal reinforcing bar 13a side (the front side of the carriage 10) are opened.

  Therefore, the operator inserts and stores the article B from the opened portion in the article receiving band 23. In this case, since the article accommodating band 23 is opened according to the size of the article B, the article B can be easily inserted. In this case, the operator does not necessarily have to arrange the support bar 21a and the support bar 21b in parallel. For example, when the article B is a shaft body formed in a tapered shape, the two support rods 21a and 21b can be arranged in a C shape in a top view along the taper of the article B.

  The operator opens the article accommodating band 23 and accommodates the articles B while moving the loading platform 20 to an appropriate position for each article B to be accommodated. In this case, the operator can position the loading platform 20 at a free position according to the size of the article B to be accommodated and accommodate the article B. Thereby, the goods B of a several kind of magnitude | size can be accommodated in the one trolley | bogie 10. FIG. Further, when the carriage 10 is moved, the worker keeps the articles 20 spaced apart from each other in order to prevent the articles B accommodated in the article storage bands 23 adjacent to each other from coming into contact with each other and being damaged. B can be accommodated. Thereby, the article B can be safely stored.

  The worker who has finished storing the article B in the loading platform 20 can move the cart 10 to a desired location. Specifically, the operator moves the carriage 10 by grasping, pushing, or pulling the columns 12a to 12d. In this case, each loading platform 20 suspended from the horizontal reinforcing bars 13 a and 13 b is shaken by the movement of the carriage 10. For this reason, the loading platforms 10 adjacent to each other may contact each other. However, since the buffer body 24 is provided between the adjacent article storage bands 23, the article B stored in the article storage band 23 is prevented from being damaged.

  When taking out the article B from the loading platform 20 in the carriage 10, the operator takes out the article B from the opened article accommodating band 23. Also in this case, since the article accommodating band 23 is opened according to the size of the article B, the article B can be easily taken out. Then, the worker moves the support bars 21a and 21b in the loading platform 20 from which the article B is taken out to the left side in the figure. As a result, the hook 22 in the loading platform 20 moves to the left side in the figure while sliding on the horizontal reinforcing bars 13 a and 13 b, so that the article accommodating portion 23 is folded in the left corner portion in the illustration in the carriage 10. As a result, it can be easily recognized that the article B is not accommodated in the cart 10, and the cart 10 can be stored in an orderly manner. In the case where the cart 10 is stored, the loading platform 20 can be removed from the horizontal reinforcing bars 13a and 13b.

  As can be understood from the above description of the operation, according to the above embodiment, the article accommodation band 23 for accommodating the article B is constituted by two rod bodies which are constituted by flexible strips and arranged to face each other. The support rods 21a and 21b are installed in a relaxed state. The support bars 21 a and 21 b that support the article storage band 23 are supported by horizontal reinforcing bars 13 a and 13 b that extend in the construction direction of the article storage band 23. Therefore, by adjusting the distance between the two support bars 21a, 21b supported by the horizontal reinforcing bars 13a, 13b, the width of the article storage band 23 in the erection direction can be increased or decreased. In this case, the upper part of the article accommodation band 23 is opened with a width corresponding to the distance between the two support bars 21a and 21b. Accordingly, articles B having a wide range of shapes and sizes can be easily stored and taken out. Moreover, the position which accommodates the articles | goods B can also be changed by changing the support position of the two support bars 21a and 21b in the horizontal reinforcement bars 13a and 13b. Thereby, the articles | goods B from which a magnitude | size and a shape differ mutually can be accommodated via a suitable space | interval, and the articles | goods B of a wider shape and magnitude | size can be accommodated compared with a prior art. Furthermore, when the article storage band 23 is not used, the state of use of the carriage 10 can be easily confirmed by moving the article storage band 23 to the corner or removing it from the horizontal reinforcing bars 13a and 13b. The cart 10 can be stored in an orderly manner.

  Furthermore, in carrying out the present invention, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the object of the present invention. In the following modifications, the same reference numerals are given to the same components as those in the above embodiment, and the description thereof is omitted.

  For example, in the said embodiment, the wall part 23a which obstruct | occludes the end part in the edge part by the side of the horizontal reinforcement stick | rod 13b in the article | item accommodation band 23 was formed. Thereby, the article B accommodated in the article accommodation band 23 can be stably held. However, a wall portion 23a that closes the end portion of the article containing band 23 on the side of the horizontal reinforcing rod 13a can also be formed. That is, the wall portions 23a may be formed at both end portions in the axial direction of the support bars 21a and 21b of the article accommodating band 23. According to this, it can accommodate more stably, protecting the edge part of the axial direction of support bar 13a, 13b in the articles | goods B. FIG. Further, a plurality of small articles B can be accommodated, and articles B having a wider range of shapes and sizes can be accommodated.

  In addition, the wall portion 23 a may not be provided for the article accommodation band 23. According to this, a long article B longer than the length in the axial direction of the support rods 21a, 21b of the article accommodation band 23 can be held.

  Moreover, in the said embodiment, it comprised so that the loading platform 20 might be supported by horizontal reinforcement bar | burr 13a, 13b by providing hook 22 on each upper surface of both ends in support bar 21a, 21b, and hooking on horizontal reinforcement bar | burr 13a, 13b. . However, as long as the loading platform 20 is supported by the horizontal reinforcing bars 13a and 13b extending along the construction direction of the article accommodation band 23, the hook 22 is not necessarily used. For example, both ends of the support bars 21a and 21b may be placed directly on the horizontal reinforcing bars 13a and 13b, or grooves along the longitudinal direction are formed in the horizontal reinforcing bars 13a and 13b. The both ends of the support bars 21a and 21b may slide in the groove. Also by these, the same effect as the above-mentioned embodiment can be expected.

  Moreover, in the said embodiment, the damage to the articles | goods B accommodated in the article accommodation zone 23 was prevented by providing the buffer body 24 in the side surface of the article accommodation zone 23 in the loading platform 10. FIG. However, the buffer body 24 is not limited to the above embodiment as long as it can prevent damage to the article B housed in the article housing band 23. For example, an elastic sheet body (for example, a urethane sheet body or a mirror mat) may be provided on the outer side surface of the article housing band 23, and the same effect as in the above embodiment can be expected. Further, when the article B is not damaged, the buffer body 24 is not necessarily provided.

  Moreover, in the said embodiment, it was set as the structure which does not provide the cover which covers the loading platform 20. FIG. However, a cover that covers at least the opening in the article storage band 23 may be provided to prevent the attachment of various foreign matters such as dust, dust, or dust to the article B stored in the loading platform 20. For example, by providing a resin sheet between the four columns 12a to 12d that are adjacent to each other, the interior surrounded by the columns 12a to 12d can be covered. According to this, it is possible to prevent various foreign matters such as dust, dust or dirt from adhering to the article B accommodated in the article accommodation band 23, and the article B can be accommodated more safely.

  In the above embodiment, the horizontal reinforcing bars 13a, 13b, 14a, and 14b are made of FRP material, the support bars 21a and 21b are made of aluminum material, and the article storage band 23 is made of cloth material. However, the material and shape of each part constituting the cart 10 including these are appropriately set according to the article B to be accommodated and the use environment, and it is naturally not limited to the above embodiment. It is.
