Abstract
Description
Technical Field
[0001] This invention relates to a simple shelter for avoiding wild animal damage.
Background Art
[0002] In recent years, in mountainous areas, rural areas, campsites, parks, etc., the appearance of large wild animals such as bears has been increasing, and cases have been reported where climbers, workers, and general users are endangered by sudden encounters. In such a situation, the need for simple evacuation facilities where people can temporarily evacuate in an emergency is increasing.
[0003] Conventionally, as measures against wild animals, metal cages, fixed evacuation huts, etc. have been used, but these are heavy and require a great deal of labor for transportation and installation at the site. In addition, fixed facilities have limited installation locations and have problems with maintenance during periods of non-use and damage caused by snow accumulation. Furthermore, at present, simple evacuation facilities with a structure that users can intuitively operate in an emergency have not been sufficiently popularized.
[0004] Therefore, a simple shelter is provided that is lightweight, has excellent transportability, can be quickly installed in the required location, and has a structure that allows users to easily evacuate and lock in an emergency.
[0005] Although there are evacuation shelters that are used in the event of disasters, these are built and installed locally and do not have a structure that allows for transportation, assembly, and disassembly. Therefore, construction requires time and cost, and procedures such as permission from the landowner are also required for installation, and there is a problem that the installation location is limited. (For example, see Patent Document 1)
[0006] While animal trapping cages are known as a reference for the structure, these are designed for capture and, once inside, the door cannot be easily opened from the inside when closed, making quick escape difficult. Furthermore, they are heavy and cannot be easily disassembled, requiring considerable effort for installation and transportation. Also, because they are not designed to be disassembled, they require a large area for storage, and there is a risk of component damage due to the weight of snow during snowfall. (See, for example, Patent Document 2) [Prior art documents] [Patent Documents]
[0007] [Patent Document 1] Japanese Patent Publication No. 2021-188313 [Patent Document 2] Utility Application No. 2024-3173 Publication [Overview of the project] [Problems that the invention aims to solve]
[0008] Therefore, the present invention aims to provide a simple shelter for protection against animal damage that can be easily disassembled and assembled for each component, installed anywhere, easily transported by vehicles as well as drones after disassembly, has a structure that allows for easy entry from the outside and exit from the inside, and easy locking of the door, and can be disassembled and stacked for storage when not in use to prevent damage caused by snow, etc. [Means for solving the problem]
[0009] This invention is a simple shelter for protection against animal damage, assembled into a box shape by detachably connecting multiple panels made of a grid-like welded wire mesh. Square side panels, a back panel, a top panel, and a bottom panel are connected to each other, and the front section is further equipped with rectangular front side panels and a rectangular front middle panel whose long side is shorter than the long sides of the side panels and the front side panels. The edges of these panels that meet each other are detachably fixed with multiple U-bolts, forming a lightweight, easily transportable structure that can be quickly assembled on-site.
[0010] Multiple protruding iron wires are provided forward from one side of the top panel to secure the front middle panel. The front middle panel is secured to the protruding iron wire positioned where the door is centered, and the side in contact with the top panel is fixed with multiple U-bolts to support it as an upward-opening door. When the door is closed, a portion of the back surface of the front middle panel overlaps with a portion of the front side panel, and a gap is formed between the bottom edge of the front middle panel and the bottom panel. This ensures that the door closes securely without interfering with obstacles on the ground.
[0011] Furthermore, U-shaped receiving openings are provided symmetrically on the inside of the front middle panel, allowing the door to be locked by inserting a rod-shaped door stopper into the U-shaped receiving opening from the inside of the cage when the door is closed. Each panel can be easily disassembled by removing the U-bolts, leaving only the multiple welded wire mesh panels, making transportation and storage easy. [Effects of the Invention]
[0012] This invention provides a lightweight and easily transportable simple shelter for protection against animal damage by using a structure in which multiple welded wire mesh panels are detachably connected with U-bolts, making on-site assembly and disassembly easy. In particular, by making the side panels, back panel, top panel, and bottom panel square, and the front side panel and front middle panel rectangular, the alignment of the panels is easy, improving work efficiency during assembly.
[0013] Furthermore, by using a structure in which the front middle panel is hooked onto multiple protruding iron wires that project forward from one side of the top panel, a pivot point for opening and closing the door can be easily formed, enabling an upward-opening door without the need for complex hinges. In addition, by using a structure in which a portion of the back surface of the front middle panel overlaps with a portion of the front side panel when the door is closed, and a gap is formed between the bottom edge of the front middle panel and the bottom panel, the door can be reliably closed without interfering with obstacles on the ground, and a stable closed state can be maintained even against external impacts.
[0014] In addition, the symmetrical U-shaped receiving openings on the inside of the front middle panel cause the openings to protrude inward from the grid of the front side panel when the door is closed, allowing for secure locking simply by inserting a rod-shaped door stopper from inside the cage. This enables evacuees to quickly and safely close the door from the inside.
[0015] Furthermore, each panel can be easily disassembled by removing the U-bolts, and after use, it can be stored in a space-saving manner by leaving only the individual panels. This makes it easy to transport and set up in mountainous areas, agricultural sites, campgrounds, parks, etc., and it is extremely useful as an evacuation system that can be quickly deployed in emergencies.

Embodiments for Carrying out the Invention
[0017] As shown in FIG. 1, the simple shelter 1 for animal damage avoidance of the present invention has a structure that can be assembled into a box shape by detachably connecting a plurality of panels made of lattice-shaped welded wire mesh with U-bolts. The side panel 2, the rear panel 3, the upper panel 4, and the bottom panel 5 are composed of square welded wire mesh panels. Two rectangular front side panels 6 are arranged on the left and right at the front part, and a rectangular front middle panel 7 whose long side is shorter than the side panel and the front side panel is provided as a door in the center.
[0018] As shown in FIGS. 1 and 2, the sides of the side panel 2, the rear panel 3, the upper panel 4, and the bottom panel 5 that contact each other are detachably fixed by a plurality of U-bolts 8, whereby a box-shaped structure can be quickly formed on-site. Similarly, the front side panel 6 is also fixed with U-bolts 8 at the front ends of the side panel 2, the upper panel 4, and the bottom panel 5.
[0019] As shown in FIGS. 2 and 4, on one side of the front end side of the upper panel 4, a plurality of protruding iron wires 9 for hooking the front middle panel 7 are provided forward. The front middle panel 7 is rotatably supported by being hooked onto the protruding iron wire arranged at the position where the door is at the front center among the protruding iron wires 9, and further, the side contacting the upper panel 4 is fixed by a plurality of U-bolts 8 to function as an upward-opening door.
[0020] As shown in Figure 3, when the door is closed, a portion of the back surface of the front middle panel 7 overlaps with a portion of the front side panel 6, and a gap is formed between the bottom edge of the front middle panel and the bottom panel. This ensures that the door closes securely without interfering with obstacles on the ground. The left and right ends of the front middle panel 7 are positioned to overlap the lattice surface of the front side panel 6, allowing it to maintain a stable closed state even against external impacts.
[0021] As shown in Figure 5, U-shaped receiving openings 10 are provided symmetrically on the back of the front middle panel 7. When the door is closed, the U-shaped receiving openings 10 protrude inward into the shelter, and the door can be easily and securely locked by inserting a rod-shaped door stopper 11 from inside the cage. This structure allows evacuees to quickly close the door from the inside and safely maintain the closed state.
[0022] The simple animal damage shelter 1 of this invention is constructed so that each panel can be attached and detached using U-bolts 8. After use, the U-bolts 8 can be removed to disassemble it into a state consisting only of multiple welded wire mesh panels. This makes it easy to transport and store, and it can be quickly carried to the necessary location in mountainous areas or agricultural work sites, and assembled and used in a short time.
[0023] The simple animal damage shelter 1 of this invention can be widely used as an evacuation facility to ensure the safety of workers and general users in areas where there is a risk of encountering large wild animals such as bears, such as mountainous areas, agricultural work sites, forestry sites, campgrounds, and around hiking trails. Because it is constructed by connecting multiple welded wire mesh panels detachably with U-bolts 8, it is easy to transport to the site and can be quickly installed where needed. Furthermore, since it can be disassembled after use and stored in a small space, it is useful as a standard piece of equipment for local governments, agricultural organizations, forestry businesses, and tourist facilities.
[0024] Furthermore, it can be used as a safety measure for workers in areas where the appearance of wild animals is a concern, and as temporary evacuation facilities to protect users in tourist areas and campgrounds, making it highly valuable in diverse industrial fields such as agriculture, forestry, tourism, and public safety.
