[0013] As shown in Figures 14, 16, 18, 19, and 21 to 23, 19 is the length at the base 2. A pair of legs 10, 10a facing each other in the hand direction... is a skater fixed between the skater and the skater. In the cross-sectional shape of the motor 19, the central portion 20 is formed to bulge in a semicircular arc shape, and the central portion Flat parts 21, 21a are integrally formed on both sides of the base 2, and the longitudinal members 7, 7a of the base 2 are integrally formed on both sides of the base 2. A skater center 22 is interposed between the skater 19 and the skater 19.

[0014] In addition, 23 is installed between the sides of the joint parts 5, 5a... of the base 2 and the bottom surface of the short members 6, 6a. (See Figure 19).

[0015] Next, the short frames 3 and 3a will be explained based on FIGS. 24 to 34. As shown in Figures 24, 25, 30 and 31, the short frames 3 and 3a have a square pipe shape. The vertical members 24, 24a and the horizontal members 25, 25a are joined to form a lower part of the vertical members 24, 24a. flat-headed rivets 26, 26a protruding inwardly are fixed to provide fitting portions 27, 27a. , fit the fitting parts 27, 27a into the sockets 11, 11a of the base 2, and attach them to the base 2. The short members 6, 6a are arranged vertically.

[0016] In addition, when the above-mentioned short members 6, 6a are erected, the flat head rivets 26 of the vertical members 24, 24a, 26a fits into the bulge portion 16 of the sockets 11, 11a... and prevents the slope of the short members 6, 6a. prevents lodging (see Figures 30 and 31).

[0017] As shown in Figures 27 to 29, 28, 28a are the upper ends of the vertical members 24, 24a (above the square pipes). The blind lids 28, 28a are blind lids attached to the end opening surface), and the blind lids 28, 28a have the lid body 29 inward. It extends integrally and hangs downward at its tip and is grounded to the upper horizontal member 25. are doing.

[0018] Note that the hanging part 30 at the tip of the lid body part 29 has a smaller diameter at the lower part, and the vertical member 24, In addition to accommodating the diameter difference between 24a and the horizontal members 25 and 25a, the protruding shape has been eliminated to prevent workers from getting suspicious. I try not to be selfish.

[0019] As shown in Figures 30 and 31, 31 is provided inside at the lower part of the pair of vertical members 24, 24a. The truss screw 31 has an oval shape in the vertical direction, and the truss screw 31 has an oval shape in the vertical direction. Support pieces 32, 32a are protruded from the inner side of the screw 31 so as to hang down from the horizontal member 25a. A beam 33 is fixed between the supporting pieces 32, 32a at the lower ends of the holding pieces 32, 32a.

[0020] As shown in FIG. 40, when the short members 6 and 6a are erected to the base 2, the Insert the lath screw 31 into the sockets 11, 11a of the base 2 and attach the flat head rivets 26, 26a. The beam 33 is grounded on the short members 6 and 6a of the base 2, and the stability is improved. is improving.

[0021] As shown in FIGS. 26, 32 to 34, 34, 34a... are the vertical members 24 of the short frames 3, 3a. , 24a, and the blind nuts 34, 34a... are vertical Two blind nuts are fixed to each outside of members 24 and 24a. To explain in detail the installation condition of 34, 34a..., the blind nuts 34, 34a... are female. a threaded portion 35, a thinned tubular portion 36 following the female threaded portion 35, and a tubular portion 36; It consists of a flange 37 formed at the end of the flange 37.

[0022] Then, insert the tubular portion 36 into the mounting hole 38 of the vertical member 24, 24a of the short frame 3, 3a. With the vertical members 24, 24a (square pipes ) from the outside to buckle and deform the tubular portion 36, and this buckled portion 39 and flange 37 Fix the blind nuts 34, 34a... to the vertical members 24, 24a using the 34, 34a... have a female threaded portion 35 inside the square pipe.

[0023] In addition, in such blind nuts 34, 34a..., the tubular portion 36 has a longitudinal thread. It may also be formed with a ret 40, 40a... or a groove.

[0024] In addition, 41, 41a... are reinforcing members fixed at an angle between the upper and lower horizontal members 25, 25a. (See Figure 24).

[0025] Next, the longitudinal frames 4 and 4a will be explained based on FIGS. 35 to 39. As shown in Figures 35, 36, and 39, the longitudinal frames 4, 4a have two L-shaped water bodies. It is formed by joining flat plates 42, 42a and a plurality of vertical plates 43, 43a between the horizontal plates 42, 42a. , L-shaped horizontal plates 42, 42a have vertical parts 44, 44a in the front and horizontal parts 45, 45 in the depth direction. It has the shape of a, and bolt holes 46, 46a are bored at both ends of the vertical parts 44, 44a. As shown in Figure 33, the vertical members 24 and 24a of the short frames 3 and 3a are Attach bolt holes 46, 46a to nuts 34, 34a... and insert the bolt holes 46, 46a through them. By tightening the bolts 47, 47a..., the short frames 3, 3a and the long frames 4, 4a are fixed. are doing.

[0026] In addition, as shown in Figs. 37 and 38, the horizontal parts 45, 45a of the horizontal plates 42, 42a are provided with Notches 48, 48a of a predetermined width are formed, and the short frame 3 is formed by the notches 48, 48a. , 3a and longitudinal frame 4, fixed state of 4a, longitudinal frame 4, 4a relative to base 2 Ensures stability when stored.

[0027] Next, we will explain the function of the returnable rack according to the present invention, leading to the shape of the present invention. To explain the process together, When transporting goods, as shown in Figure 1, the sockets 11 of the joints 5, 5a... of the base 2 are , 11a... from above, insert the vertical members 24, 24a of the short frames 3, 3a, then insert the vertical members 24, 24a into Horizontal plates 42, 42a of longitudinal frame 4, 4a to blind nuts 34, 34a of 24, 24a... Attach bolt holes 46, 46a, and tighten bolts 47, 47a... with a pneumatic screwdriver. , or use the screwdriver by hand to tighten bolts 47, 47a... Fix the longitudinal frames 4 and 4a to the frames 3 and 3a, and make the rack body 1 into a box shape. Assemble it firmly.

[0028] When storing and packing items in the rack body 1, use the short frames 3 and 3a on two sides. Work can be carried out with the frame standing upright, or with one side of the longitudinal frame 4, 4a standing upright. For example, items can be easily packed in the rack body 1 at a low position.

[0029] Also, as shown in Figures 6 and 7, when returning the container body 1, it must be assembled in the opposite direction. Remove the long frames 4 and 4a and the short frames 3 and 3a, and remove the base 2 and short frames. The rack body 1 is divided into plate-like parts so that the frames 3 and 3a and the longitudinal frames 4 and 4a are each separate parts. Unravel, place the short frames 3, 3a and the long frames 4, 4a on the base 2, and stack them. This reduces the volume of the rack body 1.

[0030] As shown in FIGS. 4 and 5, when assembling the rack body 1, , The most important thing to keep in mind is that the rack body 1 of the present invention is not constructed using a forklift. For example, they are stacked in two layers and stored in a container 49 in this state for transportation. In order to maximize the efficiency of the rack body 1, the volume of the rack body 1 must be For this purpose, the outer dimensions of the rack body 1 should be It is important to keep the internal dimensions of the antenna 49 as similar as possible.

[0031] Therefore, the first characteristic configuration to achieve the above purpose is the base 2 and the short frames 3 and 3a, when the short frames 3 and 3a are set up The hand frames 3, 3a do not tilt inward, and the short frames 3, 3a maintain their vertical standing state. In order to hold the In this case, the wall thickness of the square tube must be larger than the vertical members 24 and 24a of the short frames 3 and 3a. This amount alone causes a reduction in the internal volume of the rack body 1.

[0032] Also, in this case, vertical installation is possible, but the rack, which is one of the purposes of this invention, When the block body 1 is disassembled, stacked and folded, the short frames 3, 3a and the long frame It is difficult to ensure that rooms 4 and 4a are aligned and tidy.

[0033] That is, when the short frames 3, 3a and the long frames 4, 4a are placed on the base 2. In this case, since the base 2 has the same dimensions as the container 49, the short frame 3 is separated from the base 2. , 3a or the longitudinal frames 4, 4a protrude, once a large number of bases 2 (bases Stack short frames 3, 3a and long frames 4, 4a) on top of 2. From the raised position, attach the short frames 3, 3a and long frames to each base 2 and on the base 2. Hand frames 4 and 4a had to be separated and stacked again, making the work extremely difficult. Ru.

[0034] Therefore, the short frames 3, 3a and the long frames 4, 4a are aligned on the base 2. When stacking and folding the base 2, sockets 11 and 11a... need to be devised. This point will be discussed later, but returning to the main topic, sockets 11, 11a... and the short frame One possible method is to provide corresponding unevenness on the vertical members 24 and 24a of 3 and 3a, and in this case, For this purpose, it is sufficient to provide unevenness on two sides of the vertical members 24 and 24a in the sockets 11 and 11a, respectively. In this case, as mentioned above, the outer dimensions of the base 2 are limited by the inner dimensions of the container 49. In order to ensure that the sockets 11, 11a... In this case, as shown in Figure 17, Figure 20, Figure 30 and Figure 31, each This problem is solved by providing the bulge 16 and flat head rivets 26, 26a.

[0035] In addition, as shown in Figures 18 and 19, the legs 10, 10a... of the joints 5, 5a... Due to the limited external dimensions of the rack body 2, when the rack body 1 is stacked, the vertical In order to receive the upper ends of the members 24 and 24a, a cylindrical shape having four hanging walls is preferable. , the outer dimensions of the vertical members 24, 24a are the maximum limits, then the legs 10, 10a... have the allowable dimensions. In order to exceed It is composed of hand leg plates 14 to ensure the maximum dimensions of the rack body 1.

[0036] On the other hand, since the sockets 11, 11a... are provided with the bulges 16, the sockets 11, 11a... The lower legs 10, 10a... have limitations in terms of strength, and the base 2 during disassembly and stacking. When stacking comrades, the top of the lower base 2 sockets 11, 11a... Because the legs 10, 10a... are located, the sockets 11, 11a... are more likely to be thrown than the legs 10, 10a... The shadow area must be the same or larger, and therefore the other purpose of the legs 10, 10a... When the rack bodies 1 are stacked, the protruding portion 16 As a result, when the box-shaped rack bodies 1 are stacked, the legs 10 have to protrude. , 10a... and the vertical members 24, 24a, there is enough room for the work described below. It becomes too large, and when stacking, the lower and upper rack bodies 1 become misaligned, causing the rack body Since container 1 originally has dimensions determined from container 49 (almost the same dimensions), container 49 The rack body 1 may not be able to be stored inside the rack, or the stacking may collapse.

[0037] Therefore, as shown in Figures 27 to 29, Figures 41 and 42, a forklift truck When stacking the forklift body 1, check the accuracy of the forklift operation (delicate operations are not possible). The sockets 11, 11a... are placed on the top surfaces of the vertical members 24, 24a, ensuring a margin due to A lid portion 29 extending inwardly corresponding to the bulging portion 16 is provided to improve safety.

[0038] Furthermore, the longitudinal frames 4, 4a are affected by the shaking and inclination of the short frames 3, 3a described above. In addition to securing it with the shape of The truss screw 31 is provided inside the vertical members 24, 24a, and the truss screw 31 is inserted into the bulge 16. Therefore, this truss screw 31 also contributes to the vertically erected state of the short frames 3 and 3a. (See Figure 40).

[0039] In this way, as shown in FIG. 1, the short frames 3, 3a and the long frame are The frames 4 and 4a are installed in a rectangular shape to prevent the rack body 1 from being distorted and to be assembled in a box shape. It's standing up.

[0040] Also, the second characteristic configuration is that the short frames 3, 3a and the long frame 4 , 4a (when assembled), and the relationship between longitudinal frames 4, 4a and base 2 (when disassembled) , stacking), there are two methods when the rack body 1 is assembled. is considered, and the first method is to use a no-bolt, no-nut type. The method of providing hooking holes and hooking rivets where required can be done both during assembly and disassembly. In order to make this possible and fully utilize the engaged state, the engagement hole must be complicated, It has the drawback that precision is required, which increases processing fees and manufacturing costs, making the rack body 1 expensive. do.

[0041] Therefore, as a method to connect two types of items in a separable manner, bolts and nuts are used. Although commonly used, this invention may use ordinary bolts and nuts, or the nuts may be used together. It is impossible to use it by fixing it to the other item.

[0042] The reason for this is that when tightening bolts and nuts, there is a space around the part to be attached. However, in the present invention, the connection of the two articles requires the short frame 3. , 3a and the longitudinal frames 4, 4a, and the longitudinal members 24, 24a of the short frames 3, 3a are 40 Because it is a small square pipe of about mm, the end of the square pipe or the inner 1~2cm Even if it is possible to install and fix nuts up to It is not possible to install nuts in this area.

[0043] Therefore, in this invention, as shown in Figures 32 to 34, instead of a normal nut, Blind nuts 34, 34a... In other words, there is nothing inside the square pipe. Blind nuts 34, 34a... can be installed from the outside of the square pipe regardless of the As described later, in addition to minimizing the protrusion from the square pipe, the blind nut 34, 34a... are easy to install, and the rack body 1 is easy to assemble and disassemble. In addition, the means for connecting two articles can be manufactured and processed at low cost.

[0044] In addition, in the method of attaching a normal nut to a square pipe, the method of this invention can be used. If you attach a regular nut to the outside of the square pipe, the work and cost can be reduced considerably. Even if this is possible, a common drawback is that the presence of nuts This had the disadvantage that objects and bodies could get caught due to the protrusion of the nut. .

[0045] In addition, the purpose of the rack body 1 of the present invention is to maximize its internal volume. That is, as shown in FIGS. 4 and 5, the rack body 1 is stored in the container 49. When assembling rack body 1, remove any items (including nuts) from rack body 1. Of course, it is important that the parts (including External mounting makes no sense at all.

[0046] Another method is to attach a screw-shaped bolt with a sharp tip to the square pipe. There are also bolts that are screwed directly into the wall plate of a square pipe using a screwdriver. However, after using this type of bolt several times, the wall plate becomes a blank hole and loses its fixing effect. The rack body 1 that is lost and therefore has to be returned, assembled, and disassembled many times in the present invention. It is not applicable to

[0047] In addition to the configuration and operation described above, as shown in FIGS. 37 and 38, the longitudinal frames 4, 4a In the horizontal plates 42, 42a, there are notches at both ends of the horizontal parts 45, 45a of the horizontal plates 42, 42a. 48, the horizontal parts 45, 45a are connected to the vertical members 24 of the short frames 3, 3a. , 24a to stabilize the vertical standing condition of the short side frames 3 and 3a, and to As shown in Figure 10, when the rack body 1 is disassembled and folded, the longitudinal When placing the frames 4, 4a, one side of the sockets 11, 11a... is open, and The vertical parts of the horizontal plates 42, 42a of the longitudinal frames 4, 4a are placed inside the sockets 11, 11a of the base 2. 44, 44a to prevent the longitudinal frames 4, 4a from shifting, or to prevent the horizontal parts 45, 45a is placed in close contact with the outer surface of the base 2, and the longitudinal frames 4 and 4a are placed on the base 2. When stacked, the thickness of the horizontal portions 45, 45a disappears, allowing stacking.

[0048] Also, as shown in Figure 11, when stacking the short frames 3 and 3a on the base 2, the long Insert the vertical members 24, 24a into the sockets 11, 11a... in the same way as the hand frames 4, 4a. Prevents misalignment of the short frames 3 and 3a.

[0049] In addition, the third characteristic configuration is a forklift for transporting the rack body 1. In the relationship between the skater 19 and the skater 19, first, the rack body 1 in the present invention has a four-way difference. and the forklift claws in both the longitudinal and lateral directions of the rack body 1. Insert the rack body 1, lift it up, and transport it.

[0050] The action of the skater 19 is to lift the rack body 1 with a forklift. When the forklift is lifted up, the claws of the forklift only partially support the rack body 1. , the base 2 may be bent and the rack body 1 may be damaged or crushed, or the items on the rack body 1 may be damaged or crushed. This is to prevent cargo from collapsing and damage to goods, and when it touches the ground, the base 2 Although the situation such as crushing does not occur, this kind of situation occurs when the rack body 1 is lifted. Problems are likely to occur, so the skater 19 has a rectangular shape to have a specified strength. Thick walls are used.

[0051] Another function of the skater 19 is to move the rack body 1 onto a roller conveyor. When conveyed on a roller, it can slide smoothly on the rollers.

[0052] Therefore, as shown in Fig. 16, Fig. 18, Fig. 19, Fig. 21 to Fig. 23, the present invention The cross-sectional shape of the caterer 19 is such that the central portion 20 is bulged in a semicircular arc shape. Therefore, even if the tip of the forklift's claw collides with skater 19, skater 19 will not be able to Because of its arc shape, the forklift's claws do not collide at right angles and hit the skater 19. Skater 19 suffered little or no damage from sliding on the top surface, and as a result, The wall thickness of Skater 19 can be made thinner.

[0053] Also, lift the rack body 1 with the claws of the forklift and the forklift will move on its own. , the ground may be uneven (uneven) or have holes, making it difficult to - When a forklift tire becomes stuck, the forklift tilts with an impact. However, at this time, since both the forklift claw and the rack body 1 are made of metal, There is a danger of slipping between the two.

[0054] In addition, if various items are mixed together to be stored in the rack body 1, the rack body 1 The balance within the main body 1 is not maintained, and this kind of danger often occurs. Therefore, as shown in Figure 14, the present invention has a skateboard between the base 2 and the skater 19. Cater Center 22 is used to prevent the forklift from tilting. The claws contact the skater center 22 to suppress slipping and prevent accidents, Make it minor.

[0055] Although this kind of danger mainly occurs in the left and right directions, if it occurs in the front and rear, The lower surface of the forklift claw comes into contact with the upper surface of the motor 19, reducing the inclination and further The skater center 22 prevents the skater 19 from deflecting, reducing the risk or Also, if the forklift claw is not inserted sufficiently, the same rack body will result. 1 slope occurs, but the risk is similarly reduced in such cases.

[0056]

[Effect of the idea]

In short, the present invention allows the short frames 3, 3a and the long frames to be set upright relative to the base 2. The frames 4 and 4a are assembled freely to form the rack body 1, and when transporting goods, The rack body 1 is assembled into a box shape and the items are packed, and when the rack body 1 is returned, The rack body 1 is disassembled into plate shapes, and the base 2, short frames 3, 3a, and long frames are assembled. 4. Since 4a is plate-shaped, the volume of the rack body 1 can be reduced to reduce shipping costs and costs when returning. It is possible to recycle the rack body 1 while minimizing the The square pipe-shaped vertical members 24 and 24a have internally threaded portions 35 inside the square pipes. Attach the blind nuts 34, 34a...to the horizontal position of the longitudinal frames 4, 4a. Bolt holes 46, 46a are drilled in the vertical parts 44, 44a of the plates 42, 42a, and the bolt holes 46, 46a are Insert the bolts 47, 47a... into the blind nuts 34, 34a... and tighten the short frame. Since the longitudinal frames 4 and 4a are fixed to the frames 3 and 3a, the short frames 3 and 3a and the longitudinal frame Frames 4 and 4a are connected in bolt and nut format for easy work and operation. Also, because the nuts are blind nuts 34, 34a... the vertical members 24, 24a... The blind nuts 34, 34a... do not protrude from the base 2, the short frame 3, 3a and the longitudinal frames 4, 4a can be maximized, i.e. limited by the container 49. The rack body 1 can secure the maximum capacity for transporting goods, thereby improving the carrying capacity of goods. Also, notches 48, 48a are formed at both ends of the horizontal parts 45, 45a of the horizontal plates 42, 42a. The horizontal parts 45 and 45a are located between the opposite short frames 3 and 3a, and the short frames 3, 3a can be maintained vertically, and when disassembled or folded, horizontal parts 45, 45a are It is located on the outer surface of the base 2 to reduce the space when folded, and the vertical part 44 , 44a fit into the sockets 11, 11a... to align and organize the longitudinal frames 4, 4a. It is possible to do this, and since it is in a fitted state, it can be prevented from being lost during transportation, etc. Its practical effects are enormous.
