storage shed

Abstract

Sandbox tools and play equipment stored in metal storage sheds at kindergartens and daycare centers often become covered in sand, accumulating in the rail grooves under the door and on the floor, making it difficult to open and close the door. Metal floors also suffer from the problem of being easily scratched and rusted. In response to this problem, a floor protection mat was sometimes used to protect the floor of storage sheds, as described on page 115 of the Takubo Industries Co., Ltd. catalog in Non-Patent Document 1. However, the temperature difference between day and night caused condensation, which led to rust. Furthermore, cleaning the floor was difficult, and sand tended to accumulate in the corners of the shed, making it difficult to remove. Even with hanging doors, sand accumulated in the lower rail grooves, making it difficult to open and close the door. [Solution] The floor of the storage shed includes a slatted floor and rail grooves, and has an inclined plate between the slatted floor and the ground, so that any sand or debris that falls will automatically slide down the inclined plate to the front of the shed, and the storage shed has insect and other intrusion prevention plates on three sides around the periphery that closes the space between the slatted floor and the inclined plate.

Description

[Technical Field]

[0001] This invention relates to a storage shed that has a discharge hole for sand, garbage, etc. at the bottom of a rail groove under the door, and the fallen sand and garbage are automatically discharged to the outside front side of the storage shed via an inclined plate, so that the sand, garbage, etc. do not accumulate in the rail groove, and the door can be opened and closed easily. [Background technology]

[0002] Sandbox equipment and toys stored in storage sheds at kindergartens and nurseries tend to get covered in sand, which falls into the metal door rails and floor, causing scratches and rust, making it difficult to open and close the doors. Cleaning the door rails is also difficult.

[0003] In consideration of this problem, the door described on page 12 of the catalogue of Takubo Kogyosho Co., Ltd. in Non-Patent Document 1 is a hanging door, and although there is a drain hole at the bottom of the anti-sway rail groove at the bottom of the door, sand accumulates in the anti-sway rail groove, making it difficult to open and close the door.

[0004] Also, as described on page 115 of the Takubo Industries Co., Ltd. catalog, there were cases where the floor of the storage shed was protected with floor protection mats or sheets to prevent scratches, but the temperature difference between day and night caused condensation and rust. Furthermore, cleaning the floor was difficult, and sand would accumulate in the corners of the storage shed, making it difficult to remove. [Prior art documents] [Non-patent literature]

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a cross-sectional view of the center of a storage shed. Storage sheds are generally installed on foundation concrete blocks 19. This cross-sectional view shows sand 5 and debris that have fallen through a gap 4 in the floor and door anti-vibration rail groove 32 facing the bottom surface under the door of the storage shed, sliding down to the front of the shed via an inclined plate 6.

[0014] The storage shed doors include a hanging door 23 and a roller door 24.

[0015] 2 and 3, in the case of the hanging door 23, the door anti-sway rail groove 32 at the bottom of the door is provided with a door anti-sway rail groove frame 34. Referring to (B) of Fig. 2, when there is one hanging door 23, the door anti-sway rail groove 32 at the bottom of the door only has the door anti-sway rail groove frame 34 for one door, so the discharge hole 33 at the bottom of the door anti-sway rail groove 32 can be fully opened, so sand and dirt that has fallen through the gap in the floor will not accumulate, and the hanging door 23 can be opened and closed smoothly. When there are multiple hanging doors 23, as shown in Figure 3(A), there will be multiple anti-sway rail groove frames 34 as shown in Figures 3(A), (B), and (C), but most of the discharge holes 33 of the door anti-sway rail grooves 32 will be empty space, so sand and debris will not accumulate. In Fig. 2, cross-sectional view (A) shows the door anti-sway rail holding section, and (B) shows the sand discharge section. Also, in Fig. 3, E-E' in cross-sectional view (B) shows the door anti-sway rail holding section, and F-F' in cross-sectional view (C) shows the sand discharge section.

[0016] 4 and 5, Fig. 4 shows the structure of the roller door 24. A roller rail 43 is provided on the lower part of the door of the roller door 24, along which the rollers run. 5(B) shows the G-G' cross section of (A), and Fig. 5(C) shows the H-H' cross section of (A). Sand discharge holes 33 are provided in the gaps between the door roller rails at the door roller rail fixing part, so dirt is discharged without accumulating. Therefore, the roller door 24 can be opened and closed smoothly.

[0017] In both the hanging door 23 and the roller door 24, it is preferable that the sand discharge holes 33 have a large area, and they may be rectangular or round, and multiple holes may be provided. In the hanging door 23, the sand discharge holes 33 at the bottom of the door anti-vibration rail groove 32, and in the roller door 24, the sand discharge holes 33 at the bottom of the roller rail fixing part preferably occupy an area ratio of 20% or more. More preferably, it is 50% or more, and even more preferably, it is 90% or more.

[0018] As shown in Figures 3 and 5, the discharge hole 33 is provided large, so sand does not accumulate in the anti-vibration rail groove 32 or the door roller rail fixing part, making the door open and close smoothly.

[0019] Referring to FIG. 6, the floor of the storage shed is made of slats, so spacers 3 are attached between the floorboards 2 to ensure a gap 4, and the floor of the storage shed is also designed to prevent sand from accumulating.

[0020] The floor of the shed has a gap of 10 to 15 mm between the floorboards 2, just like a regular wooden deck, so even if sand, trash, small parts, coins, etc. are dropped in, they slide down the inclined plate 6 installed between the floorboards 2 and the ground and are automatically discharged to the front of the shed, making cleaning and maintenance easy. The shed is designed so that the floorboards 2 do not easily come off once luggage is inside. By attaching spacers 3 to the floorboards 2, gaps 4 can be maintained at regular intervals.

[0021] The floor of the storage shed of this invention can be made of resin or wood, but preferably, hard boards such as tropical ulin wood are used to ensure strength, rigidity, and durability. The board width is determined by attaching spacers 3 to the sides of commonly available boards, and the gap 4 between the boards 2 is set to approximately 10 to 15 mm, based on the design of a wood deck. Since sand particles are approximately 1 to 3 mm, leaving a gap 4 between the boards 2 of approximately 15 mm allows sand and small debris to fall and roll down the slope of the inclined plate 6, discharging it toward the front of the storage shed. The inclined plate 6 can be made of either resin or metal, but a mirror-finished stainless steel plate is preferred, as it allows sand and debris to slide easily. Opening and closing the storage shed door transmits vibrations to the inclined plate 6, facilitating the discharge of sand 5. It is also possible to force the discharge of sand 5 by running water.

[0022] Referring to Figure 7, sand 5 that falls through the gap 4 between floorboards 2 is designed to automatically slide down towards the front of the door due to the angle of inclined plate 6 and the vibration caused by opening and closing the door. The inclined plate 6 is fixed to the storage shed floor frame 1 on the opposite side from the door using an inclined plate mounting plate 11 with screws or the like.

[0023] The slope of the inclined plate 6 can be secured by fixing the inclined plate mounting plate 11 to the storage shed floor frame 1 on the opposite side of the storage shed door with screws or the like, and by placing the front side on the ground.

[0024] Since there is a possibility that insects or small animals may enter through the discharge holes 33 in the door stop groove 32 or the gaps 4 between the floorboards 2, an insect intrusion prevention plate and sand discharge plate 10 is provided as shown in Figure 7. By attaching a hinge 8 to the top of the insect intrusion prevention plate and sand discharge plate 10 and a magnet 9 to the bottom, the insect intrusion prevention plate and sand discharge plate 10 can be maintained in a raised state, making it easy to scrape out the sand 5 that has fallen through the gaps in the floor after it has been discharged.

[0025] The insect intrusion prevention board and sand discharge board 10 is made of a transparent material such as polycarbonate, so that the amount of fallen sand 5 can be confirmed. If a magnet 9 is attached to the insect intrusion prevention board and sand discharge board 10, the raised magnet 9 will stick to the door or wall surface facing the insect intrusion prevention board and sand discharge board 10, and the insect intrusion prevention board and sand discharge board 10 can be held open, making it easier to scrape out the sand 5 that has fallen through gaps in the floor.

[0026] 7 is a view from the direction of arrow C of the insect and other intrusion prevention plate / sand discharge plate 10 as seen from the direction of arrow B in Figure 1. Since the insect and other intrusion prevention plate / sand discharge plate 10 can still invade from the sides if it is only installed on the front, insect and other intrusion prevention plates 7a and 7b are also provided on both sides to prevent the intrusion of insects and small animals.

[0026] If there are discharge holes 33 or gaps 4 in the floorboards 2, air will circulate, which is likely to promote condensation, but by providing an insect and other intrusion prevention board 10 that also serves as a sand discharge board, not only can insects and small animals be prevented from entering, but air circulation will also be eliminated, which has the effect of minimizing condensation.

[0027] Referring to Figure 8, the inclined panel 6 may be attached not only to the front side but also to the left and right or front and rear. In the case of the front and rear or left and right, the inclined panel attachment portion 11 to the storage shed is eliminated, so the inclined panel holding member 21 can be attached to hold the inclined panels 16a and 16b and ensure the slope. In this case, insect and other intrusion prevention panels 17a and 17b are required, and hinges 18a and 18b are also required at the top.

[0028] Furthermore, the inclined plate 6 may be a four-way flow system, not just a two-way system (left and right or front and back). As explained above, if the inclined plate 6 is a four-way system, four insect and other intrusion prevention doors / sand discharge doors 10 are required. (B) is a view seen from the direction of the arrow D in (A).

[0029] The inclined plate 6 may be of any one of single flow, double flow, and four-way flow types, but single flow is preferred in consideration of cleaning efficiency.

[0030] Furthermore, the insect and other intrusion prevention board / sand discharge board 10 is preferably located on the front side of the storage shed.

[0031] In the above case, when soil or sand attached to footwear or clothing is brought into the storage shed and falls into the floor slats or rail grooves, this problem can be solved by providing a large discharge hole.

[0032] In FIG. 9, taking into consideration the particle size of soil and sand, multiple holes with a diameter of about 5 mm can be provided to allow for discharge.

[0033] As a means for facilitating the discharge, a broom-like brush is provided at the bottom of the door, so that soil, sand, etc. can fall down through the discharge hole when the door is opened and closed.

[0034] Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the illustrated embodiments. Various modifications and variations can be made to the illustrated embodiments within the same scope or equivalent scope of the present invention. [Industrial Applicability]

[0035] According to this invention, sand and dirt do not accumulate on the floor surface of the storage shed or on the rail groove of the door, so the door is free from scratches and rust, and can be opened and closed smoothly. [Explanation of symbols]
