Description

Technical Field

[0001] The present invention relates to a polygonal frame that can be freely assembled and disassembled.

Background Art

[0002] Conventionally, as a polygonal frame, a photo frame 1 disclosed in Patent Document 1 is known. This photo frame 1 has a frame body 5 composed of a front plate 2, an intermediate plate 3, and a rear plate 4 which are arranged side by side in the front-rear direction, with the side where the photograph is displayed defined as the front side and the back side defined as the rear side. The front plate 2 is formed with an opening 6 for taking in and out the photograph, which penetrates through a substantially central portion of the front plate 2. The intermediate plate 3 is formed with an accommodating portion 7 for accommodating the photograph, which penetrates through a substantially central portion of the intermediate plate 3 and is larger than the opening 6 of the front plate 2. Further, the intermediate plate 3 is formed with a receiving portion 8 for receiving a part of a jig for fixing the frame body 5 to a mounting surface, which is formed by notching the peripheral edge of the intermediate plate 3. Furthermore, the rear plate 4 is formed with an introduction portion 9 communicating with the receiving portion 8, which is formed by notching the rear plate 4.

[0003] According to this photo frame 1, since the photograph can be inserted into the accommodating portion 7 through the opening 6, the photograph replacement operation can be performed from the front side of the frame body 5. Therefore, the photograph replacement operation can be performed while the frame body 5 is attached to a mounting surface such as a wall surface, which facilitates the photograph replacement operation. In addition, by inserting a part of the mounting jig (for example, the head portion of a pushpin) through the introduction portion 9 and making it received in the receiving portion 8, the mounting jig is not visible from the front side of the frame body 1. This improves the appearance when the frame body 1 is attached to the mounting surface (wall surface).

Summary of the Invention

Problem to be Solved by the Invention

[0005] However, the photo frame 1 described in Patent Document 1 above does not mention the ease of assembling and disassembling the frame body 5, and it also allows the front plate 2, middle plate 3, and back plate 4 to be formed as a single unit to form the frame body 5 (paragraph

[0015] ), so it is considered that disassembling and assembling the photo frame 1 is not easy. Furthermore, the aesthetic appeal of this photo frame 1 is that the mounting jig (thumbtacks) are not visible from the front of the frame body 1, making it look good when the frame body 1 is attached to the mounting surface (wall), and not the aesthetic appeal of the photo frame 1 itself.

[0006] This invention was made in view of the aforementioned problems of the prior art, and provides a polygonal frame that can be easily assembled and disassembled, and that enhances both aesthetic appeal and practicality. [Means for solving the problem]

[0007] To solve the above problems, the polygonal frame according to claim 1 is characterized in that, in a polygonal frame consisting of a plurality of components, the components are substantially in the shape of a rectangular parallelepiped, and tenons and mortise holes are formed at both ends of the components to connect adjacent components to each other, and the components are fastened together in a way that allows them to be assembled and disassembled by a wheel-type plug that is inserted into a wheel-type plug hole formed by fitting the tenon into the mortise hole, and the components are fastened together to form a regular polygonal shape as a whole.

[0008] The characteristic of the polygonal frame according to claim 2 is that, in claim 1, the components are made of wood.

[0009] The characteristic of the polygonal frame according to claim 3 is that, in claim 1 or 2, the regular polygonal shape is a regular hexagon. [Effects of the Invention]

[0010] In the polygonal frame according to claim 1, instead of nails or adhesives, wheel-type pins are used to connect the components. These wheel-type pins are inserted to reinforce the so-called "mortise and tenon joint," which joins two components using a tenon and mortise joint. The more the wheel-type pins are inserted, the closer the two components are drawn together and the tighter the connection becomes. Therefore, in this polygonal frame, play in each component can be suppressed, improving both aesthetics and practicality. Furthermore, the two components can be easily separated by pulling out the wheel-type pins. In addition, since the components are tightly connected and form a regular polygonal shape as a whole, each component has the same shape, simplifying the components. Thus, the polygonal frame according to claim 1 is easily assembled and disassembled, improving both aesthetics and practicality. Moreover, this polygonal frame can be assembled and disassembled repeatedly without damaging the components, and it also has an educational effect in helping people understand the properties of wheel-type pins, which become stronger the more they are inserted, making it applicable to educational toys and the like.

[0011] In the polygonal frame according to claim 2, the components are made of wood, making it easy to process. Furthermore, thinned timber can be used, promoting the effective use of resources. In addition, if cypress wood is used, antibacterial effects and a calming effect from its fragrance can be expected.

[0012] In the polygonal frame according to claim 3, the outer shape is a regular hexagon. Among regular polygons, the regular hexagon has a beautiful outer shape and is particularly excellent in terms of design. Furthermore, when multiple regular hexagonal frames are combined and attached to a wall or the like, they can be freely combined in a honeycomb-like pattern without any gaps. This makes it possible to obtain a combination of regular hexagonal frames that is highly creative and exhibits excellent design. [Brief explanation of the drawing]

[Figure 6] A perspective view of the fasteners for a photo frame according to an embodiment. [Figure 7] A diagram relating to an embodiment of a photo frame, showing multiple photo frames combined. [Modes for carrying out the invention]

[0014] An embodiment of the polygonal frame according to the present invention will be described below based on the drawings. Figures 1 and 2 are a front perspective view and a rear perspective view of the photo frame 6 as a polygonal frame. This photo frame 6 is made up of six wooden components 1 of the same shape, which are combined to form a regular hexagon. The photograph 90 is fitted into a groove 2 (see Figure 3), which will be described later. In detail, the photograph 90 is a photograph or illustration sandwiched between a hexagonal thin plate 92 and a hexagonal acrylic plate 91, etc. Six wheel-type fasteners 30 are arranged on the back of the photo frame 6. These wheel-type fasteners 30 fasten the six components 1 together. Furthermore, by removing the wheel-type fasteners 30, the frame can be easily disassembled into the six components 1. Thus, because the components 1 are made of wood, they are easy to process. Furthermore, thinned wood can be used, enabling the effective use of resources. In addition, if cypress wood is used, antibacterial effects and a healing effect from the fragrance can be expected. The photo frame 6 is a regular hexagon. Among regular polygons, the regular hexagon has a beautiful outline and is particularly excellent in terms of design.

[0015] Figure 3 is a front view and a bottom view of the component 1. The component 1 has a substantially rectangular parallelepiped outer shape, and when adjacent components 1 are combined, the outer side surface 1a that becomes the outer side and the inner side surface 1b that becomes the inner side are parallel to each other. Then, contact surfaces 10 and 20 are formed at both ends in the longitudinal direction such that the angle θ1 with the outer side surface 1a is 60 degrees. In addition, substantially triangular tenon portions 11 and 21 are provided to project from both ends in the longitudinal direction. Further, continuing from the tenon portions 11 and 21, substantially triangular mortise portions 12 and 22 into which the tenon portions 21 and 11 of the adjacent component 1 are fitted are recessed. The tenon portions 11 and 21 are formed with pressing surfaces 11a and 21a that are pressed by the quick-release plug 30, and the mortise portions 12 and 22 are formed with guide surfaces 13 and 23 that guide the quick-release plug 30. In addition, the inner side surface 1b is recessed with a groove 2 into which the outer periphery of the photograph 90 is fitted. Note that in FIG. 3(2), both end portions in the longitudinal direction of the component 1 excluding the groove 2 are in a overlapping relationship when rotated 180 degrees around the center of the component 1.

[0016] Figure 4 is a partially enlarged front view and a bottom view of the photo frame 6, showing a state where the tenon portions 21 and 11 of another component 1 are fitted into the mortise portions 12 and 22 of one component 1, and the contact surfaces 10 and 20 are joined. As shown in FIG. 4(2), the inner side surface 1b is formed with a quick-release plug hole 5 into which the quick-release plug 30 is inserted.

[0017] A method for assembling the component 1 having the above configuration will be described with reference to FIG. 5. However, FIG. 5 is a view of the cut surface in FIG. 4 as seen from the V-V direction. First, as shown in FIG. 5(1), the other end of the other component 1 (the component 1 on the right side in FIG. 5) is brought close to one end of one component 1 (the component 1 on the left side in FIG. 5) as indicated by arrow A. Then, at the same time as fitting the tenon portion 21 of the other component 1 into the mortise portion 12 of the one component 1, the tenon portion 11 of the one component 1 is fitted into the mortise portion 22 of the other component 1, and the contact surfaces 10 and 20 are joined to achieve the state shown in FIG. 5(2).

[0018] Next, as shown in Figure 5(2), the wheel locator plug 30 is inserted into the wheel locator plug hole 5 as indicated by arrow B. As the wheel locator plug 30 is inserted further, the pressing surface 21a of the tenon portion 21 is pressed in the direction of arrow C by the side surface 30a of the wheel locator plug 30, and the pressing surface 11a of the tenon portion 11 is pressed in the direction of arrow D by the side surface 30b of the wheel locator plug 30. When the pressing surface 21a is pressed in the direction of arrow C, the tenon portion 21 is pressed in the direction of arrow C, and the other component 1 is pushed in the direction of the other component 1. Also, when the pressing surface 11a is pressed in the direction of arrow D, the tenon portion 11 is pressed in the direction of arrow D, and the one component 1 is pushed in the direction of the other component 1. Furthermore, since there is a step between the pressing surfaces 11a and 21a and the guide surfaces 13 and 23, the sides 30a and 30b of the vehicle-mounted plug 30 do not press against the guide surfaces 13 and 23. In this way, the further the vehicle-mounted plug 30 is inserted, the more the two components 1 are drawn together and tightly connected.

[0019] Thus, in the photo frame 6, instead of nails or adhesive, a wedge pin 30 is used to connect the two components 1. This wedge pin 30 is inserted to reinforce the so-called "mortise and tenon joint" that joins the two components 1 by tenon portions 11, 21 and mortise holes 12, 22. The more the wedge pin 30 is inserted, the closer the two components 1 are pulled together and the tighter they are joined. Therefore, in this photo frame 6, looseness in each component 1 can be suppressed, improving both the design and practicality. In addition, because the components 1 are tightly joined and form a hexagonal shape as a whole, each component 1 has the same shape, simplifying the components 1. Furthermore, this photo frame 6 has an educational effect in that it allows for repeated assembly and disassembly without damaging the components 1, and the wedge pin's properties, which allow for a stronger joint the more it is inserted, can be understood, making it applicable to educational toys and the like.

[0020] Figure 6 is a perspective view of the fastener 35. The fastener 35 is made of wood, and consists of a hook plate 36 and a rectangular parallelepiped fixing block 37. The hook plate 36 is formed as a trapezoidal thin plate with a top surface 36a and a bottom surface 36b that are parallel to each other, and has two mounting holes 36c in its central portion. The hook plate 36 and the fixing block 37 are fixed together with an adhesive such that the top surface 36a of the hook plate 36 and the top surface 37a of the fixing block 37 are flush with each other, and the two mounting holes 36c penetrate through the fixing block 37. This fastener 35 is fixed to the wall 95 by wood screws 94 that pass through the mounting holes 36c. To attach the photo frame 6 to the wall 95 using the fastener 35, the hook plate 36 of the fastener 35 fixed to the wall 95 is inserted between the thin plate 92 of the photo frame 6 and the wall 95. As a result, the inner side surface 1b of the component 1 of the photo frame 6 is supported in contact with the top surface 36a of the hook plate 36 and the top surface 37a of the fixing block 37, and the photo frame 6 is attached to the wall 95. In addition to using the fastener 35, there is also a method using strong double-sided adhesive tape to attach the photo frame 6 to the wall 95.

[0021] An example in which a plurality of photo frames 6 are attached to a wall 95 is shown in Figure 7. Figure 7(1) is a diagram in which five photo frames 6 are arranged side by side in contact with each other and attached to the wall 95. Figure 7(2) is a diagram in which one additional photo frame 6 is placed in contact above the central photo frame 6 in Figure 7(1). Figure 7(3) is a diagram in which two additional photo frames 6 are placed in contact diagonally above the added photo frame 6 in Figure 7(2). In this way, when a plurality of photo frames 6 are combined and attached to a wall 95 or the like, they can be freely combined in a honeycomb pattern without gaps. As a result, a combination of photo frames 6 that is rich in creativity and exhibits excellent design properties can be obtained.

[0022] In the photo frame 6 according to this embodiment, a wheel-type connector 30 is used to connect the component 1. Therefore, the further the wheel-type connector 30 is inserted, the closer the two component 1 are drawn together and the tighter they are connected. As a result, looseness in each component 1 can be suppressed, improving both aesthetics and practicality. Furthermore, the two component 2 can be easily separated by pulling out the wheel-type connector 30. Thus, this photo frame 6 is easily assembled and disassembled, enhancing both aesthetics and practicality.

[0023] Furthermore, in this photo frame 1, since component 1 is made of wood, it is easy to process. Thinned wood can also be used for component 1, thus promoting the effective use of resources. In addition, if cypress wood is used, antibacterial effects and a calming effect from its fragrance can be expected.

[0024] Furthermore, in this photo frame 6, the component parts 1 are tightly connected to form a regular hexagon as a whole, so each component part 1 has the same shape, which simplifies the design of the component parts 1. In addition, among regular polygons, the regular hexagon has a beautiful external shape and is particularly excellent in terms of design.

[0025] The polygonal frame of the present invention has been described above in accordance with the embodiments, but it goes without saying that the present invention is not limited to these and can be modified and applied as appropriate, as long as it does not contradict the technical idea of ​​the present invention. For example, in this embodiment, a regular hexagonal shape is used as the photo frame 6, but other shapes, such as a square or pentagonal shape, may also be used. Furthermore, in this embodiment, the polygonal frame is materialized as the photo frame 6, but the polygonal frame can also be materialized horizontally as a flower stand or a display stand.
