[0003] [Patent Document 1] Utility Model Registration No. 3206368 [Patent Document 2] Japanese Patent Application Laid-Open No. 2006-68392 Summary of the Invention [Problem to be solved by the invention]
[0004] Pet play equipment such as pet houses and cat towers are often placed against the walls of a room (for example, a living room). However, there is a need to place the pet house in the center of the room. When placed in the center of the room, there is also a need to use it as a chair or table. In other words, there is a need to develop a structure that can be freely connected to each other and that combines the functions of pet play equipment and furniture such as chairs and tables.
[0005] In view of the above problems, the present invention aims to provide a technology for assembly furniture that can be freely connected to each other and functions as both a pet toy and furniture. [Means for solving the problem]
[0006] To solve the above problem, the assembly furniture of this invention has holes in the side panels and top panel that communicate with the inside, and the direction of the holes can be freely changed for the assembly furniture to be connected.
[0007] More specifically, the assembly furniture of the present invention is assembly furniture that can be freely connected to each other, and includes: plate-shaped side panels that cover the sides and have side holes that connect to the interior; a top panel that is connected to the upper parts of the side panels and covers the upper part, and has an upper hole that is provided in a part of the top panel and connects to the interior; connecting parts that connect pieces of assembly furniture together; and a plurality of connectable parts that are provided on the side panels and the top panel and are connected to the connecting parts, and are provided so that the orientation of the upper hole can be freely changed relative to the assembly furniture to be connected.
[0008] The assembly furniture according to the present invention functions both as a pet toy and as furniture such as a chair or table. By making the assembly furniture according to the present invention out of wood, it can be gentle on pets who are likely to lick the assembly furniture. The assembly furniture may be made of resin or metal. Furthermore, the assembly furniture according to the present invention can be freely connected to each other using connecting parts and connected parts. Furthermore, multiple connected parts that connect to the connecting parts are provided, and the orientation of the upper hole can be freely changed relative to the assembly furniture to be connected. Therefore, the orientation of the upper hole can be freely changed according to the user's preference when connecting assembly furniture to each other. Furthermore, the assembly furniture has a simple configuration without a bottom plate, making it economical. Furthermore, when assembly furniture is used as a pet toy, the floor is easily soiled. With the assembly furniture according to the present invention, the floor of the room in which the assembly furniture is installed can be directly cleaned by moving the assembly furniture.
[0009] The assembly furniture of the present invention can be freely connected to each other vertically and horizontally using connecting parts and connecting portions. The assembly furniture can be a polyhedron composed of multiple flat surfaces. The polyhedron can also be composed of curved surfaces.
[0010] The side panel covers the side (horizontal direction) and has a side hole that communicates with the interior. The side panel may have any shape that can cover part or all of the side, such as a polyhedron with connected vertical surfaces. The side panel may also have a curved surface. The side hole communicates with the interior and functions as a passageway for pets, such as cats, to move between the inside and outside of the assembly furniture. The side hole also functions as an entrance / exit for items stored in the assembly furniture. The side hole may be circular or polygonal. Multiple side holes may be provided. The side holes may be a combination of holes with different shapes. For example, when the side panel is composed of four flat surfaces, the same side hole may be provided in all side panels, or different side holes may be provided. Furthermore, side holes may be provided in some of the side panels.
[0011] The top plate portion is connected to the upper portions of the side plate portions and covers the upper portion. The top plate portion only needs to be able to cover the upper portion, and can be designed to cover the upper opening formed by the side plate portions. The top plate portion can be polygonal or circular. The upper hole portion is connected to the interior and functions as a window for pets, such as cats, to peek out, or as a passageway for moving between the inside and outside of the assembled furniture. The upper hole portion also functions as an entrance and exit for items stored in the assembled furniture. The upper hole portion can be fan-shaped, semicircular, circular, or polygonal. Multiple upper hole portions may be provided. The upper hole portion may be a combination of holes of different shapes.
[0012] The connecting parts connect the pieces of knockdown furniture together. The connecting parts can be made of, for example, cylindrical rods (also called dowels). The connecting parts may also be made of polygonal rods. The connection between the side panels and the top panel may be made by the connecting parts. The connection between the upper side panels and the top panel may also be made by using the connecting parts in combination with adhesive. The connection between the side panels and the top panel may also be made by using existing fixing members such as nails or screws.
[0013] The connectable portion connects to, or fits into, the connecting portion. The connectable portion can be configured as a hole corresponding to the shape of the connecting portion, in other words, a hole that fits into the connecting portion. The connectable portion can be configured as, for example, a circular or polygonal hole. Multiple connectable portions can be provided on each of the side panel portion and the top panel portion. Multiple connectable portions can be provided so that the orientation of the upper hole can be freely changed for the assembled furniture to be connected. This allows, for example, when connecting multiple assembled furniture pieces vertically, the positions of the upper hole can be positioned differently for the upper assembled furniture piece and the lower assembled furniture piece. For example, the positions of the upper hole can be positioned alternately between the front and back sides. Furthermore, for example, when connecting multiple assembled furniture pieces horizontally with side hole sizes of different sizes, the size of the side hole can be reduced by changing the orientation when connecting them.
[0014] In the knockdown furniture according to the present invention, the side panels may be tetrahedron-shaped, the top panel may be rectangular, and the upper holes may be provided near the corners.
[0015] The assembly furniture of the present invention has tetrahedral side panels and a rectangular top panel, making it strong and easy to connect vertically and horizontally. By providing upper holes near the corners, it is possible to provide holes that communicate with the interior while ensuring the area of the top panel. As a result, when the assembly furniture is used as furniture, it is possible to ensure a seating area. Furthermore, when the assembly furniture is used as a pet playground, it is possible to ensure an area for animals such as cats to land and rest.
[0016] In the assembly furniture according to the present invention, the side panels are tetrahedrons, the top panel is rectangular, the upper holes are provided near the corners, and the connection parts are arranged so that when the assembly furniture is connected vertically, the upper assembly furniture can be connected by rotating it 90 degrees relative to the lower assembly furniture, based on an imaginary vertical axis passing through the center of the assembly furniture.
[0017] According to the present invention, the upper assembly piece of furniture can be freely connected to the lower assembly piece by rotating them by 90 degrees at a time. In other words, the upper and lower assembly pieces can be connected vertically so that the positions of the upper holes are offset. The above angles are merely examples, and may be 45 degrees or other angles.
[0018] The assembly furniture of the present invention may further include a ladder section having steps, and the ladder section may have a connecting section that is connected to the connecting section, and the connecting section may have a connecting section for connecting the ladder section to at least one of the side panel section and the top panel section.
[0019] The assembly furniture according to the present invention further includes a ladder section, which increases the degree of freedom in assembly. As a result, the degree of freedom in the uses of the assembly furniture increases. When the assembly furniture is used as furniture, the ladder section can be used as a seat or storage space. When the assembly furniture is used as a playground for pets, the ladder section can be used as a staircase for animals such as cats to climb up and down. [Effects of the Invention]

In the following explanation, as shown in FIG. 1, the left front side of FIG. 1 will be described as the front.
[0024] The assembly furniture 1 is made of wood and functions both as a pet toy and as furniture such as a chair or table. The assembly furniture 1 may be made of other materials, such as resin or metal. The assembly furniture 1 may also be made of a combination of different materials. The assembly furniture 1 can be used alone, but it can also be freely connected to other assembly furniture pieces 1 in the vertical (up-down) and horizontal (left-right, front-back) directions using the connecting parts 4 and the connected parts 5 (see FIGS. 1 and 2). The orientation of the upper holes 31 of the assembly furniture 1 can be freely changed according to the user's preference when connecting the assembly furniture pieces 1 to each other. Examples of pets include cats and dogs. The assembly furniture 1 can be used as a cat tower by stacking and connecting the pieces vertically (up-down). Therefore, the assembly furniture 1 is suitable for use as a cat toy. Examples of furniture include chairs, tables, storage furniture, etc.
[0025] The assembly furniture 1 shown in Figures 1 and 2 is configured by connecting three box-shaped, in other words, hexahedral, assembly furniture pieces 1 without a bottom plate to a ladder section 6. When the assembly furniture 1 is used alone, or when distinguishing it from assembly furniture 1 made up of multiple assembly furniture pieces 1 connected together, it is also called a single assembly furniture piece 1 or a box-shaped assembly furniture piece 1. The assembly furniture 1 shown in Figures 1 and 2 is connected in two pieces (two levels) vertically (up and down) and two pieces horizontally. The assembly furniture 1 may be further connected by stacking them vertically, for example, to form three or four levels.
