DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS EXAMPLES

[0013] In Figures 1 to 4, a prefabricated storage box (hereinafter also referred to as a storage box) 1 of the present invention is a cubic storage box with an open bottom end 2, and a door panel 4a for opening and closing an opening 3 for access provided in the storage box 1 is arranged to open outward as shown by arrow F in Figure 2, and the door panel 4a is configured to hold the opening 3 for access closed via a locking device 5.

[0014] The storage box 1 has a cubic frame 6 shown in Fig. 4, which is formed by connecting rods of the same construction as required in this embodiment. In this embodiment, the rods are collectively indicated by the reference numeral 7.

[0015] The cubic frame 6 comprises a pair of left and right front support rods 8a, 8b arranged on the front side, a pair of left and right rear support rods 9a, 9b arranged on the rear side, a front upper connecting rod 10 connecting the upper ends of the left and right front support rods 8a, 8b, a front lower connecting rod 11 connecting the lower ends of the left and right front support rods 8a, 8b, a rear upper connecting rod 12 connecting the upper ends of the left and right rear support rods 9a, 9b, a rear lower connecting rod 13 connecting the lower ends of the left and right rear support rods 9a, 9b, and a front upper connecting rod 14 connecting the upper end of the front support rod 8a located on the front left side and the rear support rod 9a located on the rear left side. the upper end of the front support rod 8b located on the right front side and the upper end of the rear support rod 9b located on the right rear side; and a connecting joint 20 which enables each of the above connections to be made.

[0016] Of the cubic frame 6 having such a configuration, two panels 4, 4 having equal widths and lengths are attached to each of the five faces 22a, 22b, 22c, 22d, 22e, excluding the lower end face 22A, of the six faces, in a juxtaposed state with their edges 23, 23 abutting each other, as shown in Figure 3.

[0017] In this embodiment, these panels 4 are configured as horizontally long rectangular mesh panels made of synthetic resin. The size of the mesh is set to a size that can prevent birds such as crows from pecking through the mesh at the items contained in the containment box 1. The length of the long side of the extension direction of the panel 4 is set to about 525 mm, and the length of the short side is set to about 262 mm.

[0018] In this embodiment, a plurality of panels 4, for example, four panels, out of the total ten panels 5 are designated as the door panels 4a, 4a, 4a, 4a.

[0019] In this embodiment, the front support rods 8a, 8b, the rear support rods 9a, 9b, the front upper connecting rod 10, the front lower connecting rod 11, the rear upper connecting rod 12, the rear lower connecting rod 13, the left upper connecting rod 15, the left lower connecting rod 16, the right upper connecting rod 17, and the right lower connecting rod 19 are configured as resin-coated pipes with a circular cross section and their outer diameter is set to approximately 16 mm.

[0020] The length of one side of the cubic frame 6 is set to about 565 mm. Eight connecting joints 20 are used to configure the cubic frame 6, and all of these connecting joints 20 have the same three-way connection structure. For example, as shown in Fig. 5, in the case of connecting the rear support rod 9a, the left lower connecting rod 16, and the rear lower connecting rod 13, the connecting tubular portion 27 into which the connecting end portions 26, 26 of the rods 13, 16 intersecting at right angles are press-fitted is connected and integrated with its base portions 29, 29 in a right-angle intersecting state, and the connecting tubular portion 27 is provided in an upright state at the intersection.

[0021] As shown in, for example, Figures 6 to 10, the door panel 4a is provided on both sides of one end 31 in its extension direction (longitudinal direction) with pivot cylinders 33, 33 for inserting one of the rods 7a (Figure 6) of the left and right rods 7, 7 constituting the access opening 3 (Figure 2). With the rod 7a inserted into the pivot cylinders 33, 33, the door panel 4a is rotated in a plane perpendicular to the axis of the rod 7 (7a) as shown by the arrow in Figure 2. F The opening is configured to open outward as shown by the arrow.

[0022] Also, as shown in Figs. 6-10, the other end 35 of the door panel 4a is provided with a C-shaped retaining cylinder 36 constituting the locking device 5 (Figs. 1-2) at, for example, the center of the other end 35. The C-shaped retaining cylinder 36 is rotatable around a width direction line L (in this embodiment, the axis of a circular shaft 42 described later) near the other end 35, and is provided with a C-shaped retaining cylinder portion 37 into which the other bar 7b (Fig. 6) of the left and right bar members 7, 7 constituting the insertion / removal opening 3 can be detachably fitted. In the fitted state, as shown in Fig. 10(B), the outer peripheral surface 39 of the bar member 7b and the inner peripheral surface 40 of the C-shaped retaining cylinder portion 37 can slide relative to each other. In this embodiment, the inner diameter of the C-shaped retaining cylinder portion 37 and the diameter of the bar member 7b are set to be approximately the same.

[0023] 6 to 10, on both sides of the inner edge 41 of the C-shaped holding portion 37, C-shaped bearing portions 43 are provided, which are provided on both sides of the center of the other end portion 35 of the door panel 4a and into which a circular shaft portion 42 extending in the extension direction of the other end portion 35 can be fitted. The circular shaft portions 42, 42 are fitted into the C-shaped bearing portions 43, 43 on both sides, so that the C-shaped holding cylinder 36 can freely rotate around the width direction line L. Also, a tab 47 is provided protruding from an outer surface 45 of the C-shaped holding cylinder 37 at a position slightly away from the outer edge 46. In this embodiment, as shown in Figures 1-2 and 6-8, curved pieces 50, 50 are protrudingly provided on both sides of the other end 35 of the door panel 4a that sandwich the C-shaped retaining cylinder 36, and are in contact with and cover the circular outer peripheral surface 49 of the other rod material 7b that constitutes the access opening 3.

[0024] The remaining panel 4b (a type of the panel 4) excluding the door panel 4a having such a configuration has connecting cylinders 52 at both end portions 51, 51, through which the rod material 7 constituting the cubic frame body 6 is tightly inserted, as shown in Figures 11 and 12.

[0025] In the storage box 1 shown in FIG. 1, the two door panels 4a, 4a are attached to the upper end surface 22e and one side surface 22a of the six surfaces of the cubic frame 6 (FIG. 4) as shown in FIGS. 1 and 2, with their edges 23, 23 in contact with each other as shown in FIG. 3, and each door panel 4a, 4a is attached to the upper end surface 22e and one side surface 22a of the six surfaces of the cubic frame 6 (FIG. 4) as shown in FIG. F It can be opened outward as shown.

[0026] Fig. 1 shows a state in which the door panels 4a, 4a close the opening 3, 3 for access. In this closed state, as shown in Figs. 10(A) and (B), the other bar 7b is fitted into and held by the C-shaped holding portion 37 of the C-shaped holding cylinder 36. In this closed state, as shown in Figs. 1 and 6 to 7, both curved pieces 50, 50 come into contact with the circular outer circumferential surface 49 of the resin-coated pipe, which has a circular cross section, on both sides of the C-shaped holding cylinder 36. This stably holds the state in which the door panel 4a closes the opening 3 for access.

[0027] Now, consider a case where, when an item is pushed into the storage box 1, a large load acts from the inside of the storage box 1 outward on the door panel 4a in the closed state, as shown in Figure 13, causing the door panel 4a to bulge outward and deform as indicated by the dotted line.

[0028] In this case, as shown in Fig. 10(B), due to the rotational movement of the connecting portion 53 between the C-shaped bearing portion 43 and the circular shaft portion 42 around the width direction line L (Fig. 7) and the relative sliding action between the outer peripheral surface 39 of the other bar material 7b and the inner peripheral surface 40 of the C-shaped holding tube portion 37, the C-shaped holding tube portion 37 rotates in a direction to be wound around the other bar material 7b as shown by arrow F1 in Fig. 10(A)(B). As shown by arrow F2 in Fig. 10(A), the C-shaped holding tube portion 37 does not rotate in a direction to come off the other bar material 7b (direction shown by arrow F2 in Fig. 10(A)). Therefore, when an outward load is applied in this way, the C-shaped holding tube body 36 is unlikely to come off the other bar material 7b, and the closed state of the door panel 4a can be maintained.

[0029] Thus, a major feature of the present invention is that when an outward load acts on the door panel 4a from inside the storage box 1, the C-shaped retaining tube portion 37 is configured to rotate in a direction to be wrapped around the other rod material 7b by the rotational action about the width direction line L and the relative sliding action.

[0030] When removing the stored items stored in the storage box 1 having such a configuration, the C-shaped holding cylinder 36 is rotated in a direction to expand the C-shaped holding cylinder portion 37 by gripping the tab 47 for the required item in the door panel 4a, and the other bar material 7b is removed from the C-shaped holding cylinder portion 37. After that, when closing the door panel 4a, the C-shaped holding cylinder portion 37 is pressed toward the other bar material 7b. When pressed in this manner, the C-shaped holding cylinder portion 37 elastically expands and the other bar material 7b is fitted into the C-shaped holding cylinder portion 37, and the other bar material 7b is elastically held by the C-shaped holding cylinder portion 37, so that the door panel 4a is maintained in a closed state.

[0031] 1 shows an example of how the storage box 1 is used, in which the storage box 1 is installed on the ground 55 in a backyard or the like with the open lower end 2 facing downward. The installed storage box 1 is fixed to the ground by a U-shaped or other pressing pin member that is driven into the ground as appropriate. In this state, a large amount of collected fallen leaves, cut weeds, thinned fruits and leaves, damaged vegetables and fruits, field residues, household food waste, and other storage items are thrown into the storage box 1 through the loading and unloading opening 3 (FIG. 2) formed by opening the door panel 4a on the top 56 of the box.

[0032] After putting these in, the door panel 4a is closed. By closing the door panel 4a in this way, it is possible to block the entry route of crows and harmful animals into the storage box 1, and to prevent damage to the stored items. Also, by closing the door panel 4a in this way, there is no risk of the stored fallen leaves, weeds, etc. being blown away by the wind.

[0033] As shown in FIG. 1, the storage box 1 is placed on the ground 55 with the open lower end 2 facing down, so that the contents 25 in the storage box 1 and the microorganisms from the ground 55 can come into good contact with each other. In particular, in this embodiment, all of the panels 4 constituting the storage box 1 are made of mesh plates, so that the ventilation in the storage box 1 can be ensured through the mesh of the mesh plates, and the sunlight can be well taken in through the mesh. As a result, the decomposition of the contents by the microorganisms in the storage box 1 can be accelerated, and composting can be promoted. In addition, since all of the panels 4 are made of mesh plates, the progress of composting inside the storage box 1 can be confirmed through the mesh of the panels 4.

[0034] When removing compost from the storage box 1, taking into consideration that composting takes place in the storage box 1 from the bottom side in contact with the ground to the top, for example, as shown in Figure 2, the upper door panel 4a1 is kept closed to prevent the uncomposted contents on the upper side from going out, while the lower door panel 4a2 is opened to scrape out the compost on the lower side. Note that if the entire contents have been composted, both the upper and lower door panels 4a1 and 4a2 are opened together to scrape out the compost.

[0035] The storage box 1 may be used not for long-term storage for composting, but for short-term storage purposes to dry out large amounts of fallen leaves and weeds, reduce their volume, and make them easier to dispose of as garbage.

[0036] The storage box 1 can also be installed under a eaves or in a shed and used as a temporary storage area for bagged household waste until collection day. In this case, too, when a bag of waste is pushed into the storage box 1, a large load acts from the inside to the outside of the storage box 1, and the door panel 4a may bulge outward and deform. In this case, too, for the same reason as above, the C-shaped holding cylinder 36 is unlikely to come off the other bar (bar 7b shown in FIG. 10).

[0037] In this way, when the storage box 1 is used as a temporary storage area for garbage, the two door panels 4a, 4a attached to the top and side surfaces of the storage box 1 are both opened to store garbage bags inside the storage box 1. The stored garbage bags can be removed by opening the door panels in the same way.

[0038] When the storage box 1 is used as a temporary storage area for garbage, the remaining panel 4b may be attached to the lower end 22A of the cubic frame 6 in a juxtaposed state with their edges 23, 23 abutting against each other. EXAMPLES

[0039] The present invention is by no means limited to the above-mentioned embodiment, and it goes without saying that various design modifications are possible within the scope of the claims. Examples thereof are as follows.

[0040] (1) Each of the rods 7 may be configured as a resin-coated pipe having a circular cross section as described above, or may be configured as a solid wooden rod, for example. The structure of the connection between the rods 7, 7 by the connecting joint 20 is not limited to the connecting method in which the connecting end portion 26 of the rod 7 is press-fitted into the connecting tubular portion 27 of the connecting joint 20 as shown in the above embodiment. For example, when the rod 7 is shaped like a pipe as shown in Fig. 14, a connecting means can be used in which the connecting shaft portion 60 of the connecting joint 20 is press-fitted into a hole portion 59 forming an end portion of the through hole of the rod 7. Alternatively, when the rod 7 is configured as a solid rod, a connecting means can be used in which the connecting shaft portion 60 of the connecting joint 20 is press-fitted into a connecting hole 62 provided so as to open at an end face 61 of the rod 7 as shown in Fig. 15.

[0041] (2) The panel 4 is an embodiment 1In addition to being configured as a mesh plate as shown in FIG. 1, it may also be configured as a plate-shaped panel without mesh. For example, when storing household food waste in the storage box 1, it is preferable to use such a plate-shaped panel without mesh in order to conceal the garbage and to prevent odors from escaping from the storage box as much as possible. The panel 4 may also be a combination of a mesh plate and a plate-shaped panel without mesh.

[0042] (3) The location where the door panel 4a is attached to the surface of the cubic frame 6 can be freely set to a surface that is convenient for use, taking into consideration the purpose of use of the storage box 1 and its installation location (such as installation in a corner or along the wall of a building). also, The outward opening direction of the door panel 4 in plan view or side view can be freely set. Regarding the mounting locations of the door panel 4a, for example, one or two door panels 4a can be mounted on adjacent side portions or opposing side portions. In this case, the door panel may not be mounted on the top surface of the storage box 1.

[0043] (4) In the storage box 1 of the present invention, the locking device 5 for holding the door panel 4a in the closed state can be configured using the C-shaped retaining cylinder 36, as well as various types of fitting means with the rod material that constitutes the loading / unloading opening 3, or various types of known means having a simple locking structure.

[0044] (5) The storage box 1 according to the present invention may be installed indoors for the purpose of storing small items, etc.

[0045] (6) The size of the cubic frame 6 can be set to a required size taking into consideration the size and amount of items to be stored in the storage box 1. [Explanation of symbols]
