Description

[Technical Field]

[0001] The present invention relates to a framing material and a partition. [Background technology]

[0002] 2. Description of the Related Art There exists a frame material in which a decorative cover member is attached to a rigid, long core material. Patent document 1 describes a frame material in which a groove with a C-shaped cross section extending longitudinally is formed on the side of the core material, and a locking portion provided on the back surface of the cover member is fitted into this groove to attach the cover member to the core material, thereby covering the entire side of the core material with the cover member. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-074161 Summary of the Invention [Problem to be solved by the invention]

[0004] According to the frame material described in Patent Document 1, by attaching a decorative cover member to a core material, the strength of the frame material is ensured by the core material, while the design of the frame material is improved by the cover member, making it possible to achieve greater freedom in terms of exterior design. Specifically, by painting or decorating the surface of the cover member in a manner that matches the surrounding environment, the appearance of the frame material can be made to harmonize with the surrounding environment, creating a sense of unity with the surroundings.

[0005] However, there is a demand for further improvements in functionality and convenience with respect to frame materials. For example, in conventional frame materials, the cover member covers the entire side surface of the core member, which tends to make the frame material have a monotonous appearance. As a result, when the frame material is erected on the floor and used as a pillar member, it is difficult to apply different paint colors to the left and right sides of the cover member, even if you want to harmonize the appearance with other members that are connected to the frame material by sandwiching it.

[0006] Furthermore, because conventional frame materials are configured such that the entire side of the core material is covered by a single cover member, when replacing the cover member due to deterioration or damage, the entire cover member must be removed from the core material and replaced. Because the entire cover member must be replaced, there are concerns that the replacement process will be cumbersome and expensive.

[0007] Therefore, an object of the present invention is to provide a frame material that is highly functional and convenient. [Means for solving the problem]

[0008] The frame material of the present invention comprises a core material that is shaped like a rectangular pillar that is long in one direction and has corners extending in the one direction, namely a first corner and a second corner adjacent to it; a first cover member that is attached to the core material so as to straddle a pair of side surfaces that sandwich the first corner and covers the first corner over a predetermined range in the one direction; and a second cover member that is attached to the core material so as to straddle a pair of side surfaces that sandwich the second corner and covers the second corner over a predetermined range in the one direction, and a portion of the side surface of the core material that is sandwiched between the first corner and the second corner is exposed between the first cover member and the second cover member. This configuration allows for greater freedom in exterior design and reduces the effort and cost required to replace components when they deteriorate. Furthermore, the sides of the core material can function as decorative surfaces, allowing for even greater diversification of designs.

[0009] The core material of the frame material of the present invention may have a pair of first locking portions protruding from each of a pair of side surfaces that sandwich the first corner portion, and a pair of second locking portions protruding from each of a pair of side surfaces that sandwich the second corner portion, and the first cover member may have a pair of first locking receiving portions that respectively receive the pair of first locking portions, and be attached to the core material with the pair of first locking portions locked to the pair of first locking receiving portions, and the second cover member may have a pair of second locking receiving portions that respectively receive the pair of second locking portions, and be attached to the core material with the pair of second locking portions locked to the pair of second locking receiving portions. According to this configuration, it is possible to suppress displacement of the first and second cover members in a cross-sectional direction perpendicular to one direction, and to attach the first and second cover members securely to the core material.

[0010] The first cover member of the frame material of the present invention has a pair of first end portions facing each of the side surfaces of the core material sandwiched between the first corner portion and the second corner portion and each of the other side surfaces adjacent to the side surfaces across the first corner portion, and is configured so that each of the pair of first end portions abuts against the opposing side surfaces of the core material to prevent rotation of the first cover member relative to the first corner portion; and the second cover member has a pair of second end portions facing each of the side surfaces of the core material sandwiched between the first corner portion and the second corner portion and each of the pair of second end portions abuts against the opposing side surfaces of the core material to prevent rotation of the second cover member relative to the second corner portion. According to this configuration, rotation of the first cover member and the second cover member about their respective corners can be prevented, and the first and second cover members can be attached to the core material in a more stable state.

[0011] The first and second cover members of the frame material of the present invention may be made of a material different from that of the core material. According to this configuration, appropriate materials can be selected and used for the core material and the first and second cover members.

[0012] The first and second cover members of the frame material of the present invention may be made of wood, and the core material may be made of aluminum. This configuration ensures the strength of the core material, reduces the weight of the entire frame material, and also gives the frame material an appearance and texture that is characteristic of wood.

[0013] The core material of the frame material of the present invention may be painted or decorated in a color different from that of at least one of the first cover member and the second cover member. This configuration allows for greater freedom in exterior design.

[0014] The first cover member and the second cover member of the frame material of the present invention may be painted or decorated in different colors. This configuration allows the frame material to harmonize in appearance with other components used together.

[0015] The core material of the frame material of the present invention is formed with a rectangular cross section and has, in addition to the first and second corners, a fourth corner located diagonally opposite the first corner and a third corner located diagonally opposite the second corner, and the frame material may further include a third cover member covering the third corner and a fourth cover member covering the fourth corner. This configuration allows the appearance of the frame material to have a sense of unity and uniformity, and furthermore, it is possible to effectively protect the corners of the core material from damage due to contact from the outside.

[0016] The core material of the frame material of the present invention is formed with a rectangular cross section and has, in addition to the first and second corners, a fourth corner located diagonally opposite the first corner and a third corner located diagonally opposite the second corner, and the first cover member extends from the side surface sandwiched between the first corner and the second corner, over the first corner, to the third corner, covering the entire side surface of the core material sandwiched between the first corner and the third corner, and the second cover member extends from the side surface sandwiched between the first corner and the second corner, over the second corner, to the fourth corner, covering the entire side surface of the core material sandwiched between the second corner and the fourth corner. With this configuration, the appearance of the frame material can have different impressions depending on whether the side where part of the core material is exposed is on one side or the side that is entirely covered by the cover member, thereby realizing a design that suits the use of the frame material.

[0017] The partition of the present invention comprises a pair of the above-mentioned frame members and a panel member arranged between the pair of frame members, and the pair of frame members are arranged so that the side faces sandwiched between the first corner portion and the second corner portion face in the same direction as the surface of the panel member. This configuration makes it possible to provide a partition equipped with a highly functional and convenient frame material.

[0018] The pair of frame members of the partition of the present invention may each have a core member formed with a rectangular cross section, and in addition to the first and second corners, have a fourth corner diagonally opposite the first corner and a third corner diagonally opposite the second corner, and may further include a third cover member covering the third corner and a fourth cover member covering the fourth corner, wherein the first cover member and the third cover member are spaced apart from each other so as to expose a portion of the side of the core member sandwiched between the first corner and the third corner, and the second cover member and the fourth cover member are spaced apart from each other so as to expose a portion of the side of the core member sandwiched between the second corner and the fourth corner, and the panel member may have a first protrusion located in the gap between the first cover member and the third cover member of one of the frame members, and a second protrusion located in the gap between the second cover member and the fourth cover member of the other frame member. According to this configuration, the number of parts can be reduced, and the panel member can be stably supported by the pair of frame members.

[0019] The pair of frame members of the partition of the present invention may be such that one of the first and second cover members, which is closer to the panel member, is painted or decorated in the same color as the panel member. This configuration allows the frame material and the panel member to have a harmonious appearance. [Effects of the Invention]

[0022] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0023] (Partition configuration) As shown in FIG. 1, a frame material 1A according to a first embodiment of the present invention is used as an element that constitutes a partition P. Partitions P, also called screens, are used to separate indoor spaces, for example, rooms, or to provide privacy. Partitions P may be installed not only in rooms or living spaces intended for human habitation, but also in other places, such as warehouses or other places intended for storing goods. Partitions P can be used not only indoors, but also outdoors.

[0024] As shown in FIGS. 1 and 2, the partition P is generally flat and is installed in a state where it stands vertically relative to the floor surface of the installation location. The partition P includes a frame member 1A according to this embodiment and a panel member 2. The partition P is constructed by placing frame materials 1A on the left and right ends of flat panel members 2, and combining these paired frame materials 1A so that the panel member 2 is sandwiched between them. The frame materials 1A and the panel member 2 are fastened together by appropriate means to prevent them from being separated easily or unintentionally by the user.

[0025] In this embodiment, one panel member 2 is supported by a pair of frame members 1A. However, the number of panel members 2 supported by the pair of frame members 1A is not limited to one, and may be multiple. For example, two panel members 2 are arranged with their end faces butting against each other and connected to each other, and the panel members 2 thus integrated are supported by a pair of frame members 1A.

[0026] (Frame material composition) Here, the frame material 1A according to this embodiment will be described with reference to FIGS. For convenience, the direction indicated by the arrows extending up and down relative to the plane of the paper in Figure 3 is referred to as the front-to-rear direction D1 of the frame material 1A, and the direction indicated by the arrows extending left and right is referred to as the left-to-right direction D2 of the frame material 1A. The direction perpendicular to each of these two directions D1 and D2 is the up-down direction of the frame material 1A, which coincides with the longitudinal direction of the frame material 1A.

[0027] (Core material composition) The frame material 1A includes a core material 11 and cover members 21 to 24 as main components according to this embodiment. The core material 11 has an overall rectangular columnar shape that is long in one direction, and is formed into a rectangular or parallel cross-section in a horizontal direction parallel to the front-rear direction D1 and the left-right direction D2. In this embodiment, the core material 11 has the same dimensions in the front-rear direction D1 and the left-right direction D2, and the cross section is substantially square. The core material 11 has four corners 111 to 114, and these four corners 111 to 114 extend parallel to one another in the same direction as the direction in which the core material 11 extends as a whole.

[0028] In the following description, for convenience, of the four corners 111 to 114, corner 111 located at the upper left of the paper surface will be referred to as the "first corner," corner 112 located at the upper right will be referred to as the "second corner," corner 113 located at the lower left will be referred to as the "third corner," and corner 114 located at the lower right will be referred to as the "fourth corner." The first corner 111 and the second corner 112 are adjacent to each other in the left-right direction D2, and the third corner 113 and the fourth corner 114 are also adjacent to each other in the left-right direction D2. On the other hand, the first corner 111 and the third corner 113 are adjacent to each other in the front-rear direction D1, and the second corner 112 and the fourth corner 114 are also adjacent to each other in the front-rear direction D1. Here, the first and second corners 111, 112 are located forward of the third and fourth corners 113, 114. The core material 11 has a shape that is mirror-symmetrical with respect to a vertical plane that passes through the center of the cross section and extends in the front-to-back direction D1, and also mirror-symmetrical with respect to a vertical plane that passes through the center of the cross section and extends in the left-to-right direction D2.

[0029] (Configuration of cover member) The cover members 21 to 24 are attached to the first corner 111, the second corner 112, the third corner 113 and the fourth corner 114, respectively. In other words, in this embodiment, a first cover member 21, a second cover member 22, a third cover member 23 and a fourth cover member 24 are provided, and the first cover member 21 is attached to the first corner portion 111, the second cover member 22 is attached to the second corner portion 112, the third cover member 23 is attached to the third corner portion 113, and the fourth cover member 24 is attached to the fourth corner portion 114. The first to fourth cover members 21 to 24 have the same shape as one another, and can be attached to any of the first to fourth corners 111 to 114 by changing the orientation. The configuration of the cover members 21 to 24 according to this embodiment and the attachment structure to the core material 11 will be described below, taking the first cover member 21 as a representative example.

[0030] As shown in FIG. 4(a), the core 11 has a pair of first locking portions 131a and 131b that protrude from a pair of side surfaces 121 and 122 that sandwich the first corner portion 111, respectively. For convenience, of the two side surfaces 121, 124 facing in the front-rear direction D1, the side surface 121 facing upward relative to the paper surface is referred to as the front surface, and the side surface 124 facing downward relative to the paper surface is referred to as the rear surface. Furthermore, of the two side surfaces 122, 123 facing in the left-right direction D2, the side surface 122 facing leftward relative to the paper surface is referred to as the left side surface, and the side surface 123 facing rightward relative to the paper surface is referred to as the right side surface. One first locking portion 131a protrudes perpendicularly to the front surface 121 from the left end of the front surface 121, and the other first locking portion 131b protrudes perpendicularly to the left surface 122 from the front end of the left surface 122. Both first locking portions 131a and 131b are flat or rectangular, have an appropriate thickness, and extend over the entire core material 11 in one direction in which the core material 11 extends. The height to which each of the pair of first locking portions 131a, 131b protrudes, i.e., the dimension in the direction perpendicular to the side surfaces 121, 122, can be set appropriately taking into consideration the mounting strength when the first cover member 21 is attached.

[0031] (Cover member mounting structure) As shown in FIG. 4(b), the first cover member 21 includes a pair of first locking receiving portions 211a and 211b that respectively receive the pair of first locking portions 131a and 131b. The first cover member 21 has a notch n1 that fits the outer shape of the first corner portion 111, and the notch n1 forms an inner surface 212 facing the front surface 121 (hereinafter referred to as the "front-facing surface") and an inner surface 213 facing the left side surface 122 (hereinafter referred to as the "left-facing surface"). The first lock receiving portions 211a, 211b are both formed as grooves in the first cover member 21. One of the first lock receiving portions 211a extends perpendicularly from the front facing surface 212 to the front surface 121, and has an inner surface shape that can receive the first locking portion 131a protruding from the front surface 121. The other first lock receiving portion 211b extends perpendicularly from the left facing surface 213 to the left side surface 122, and has an inner surface shape that can receive the first locking portion 131b protruding from the left side surface 122.

[0032] As shown in Figure 3, the first cover member 21 is attached to the core material 11 with the first locking portions 131a and 131b fitting into the first locking receiving portions 211a and 211b, respectively, and with the first locking portions 131a and 131b locked by the first locking receiving portions 211a and 211b, respectively. In this attached state, the first cover member 21 is positioned so as to straddle the side of the core material 11 that sandwiches the first corner portion 111, specifically, between the left end of the front surface 121 and the front end of the left side surface 122. The first cover member 21 does not need to extend over the entire core material 11 in one direction in which the core material 11 extends, but can be arranged over an appropriate range so as to cover a portion of the first corner portion 111 in this one direction. For example, the entire core material 11 in one direction can be divided into multiple ranges, and each of these multiple ranges can be covered by a separate first cover member 21.

[0033] The same applies to the second cover member 22, the third cover member 23 and the fourth cover member 24. The second cover member 22 is provided with a pair of second locking portions 132a, 132b that protrude from the front surface 121 and the right side surface 123 of the core material 11 that sandwich the second corner portion 112, respectively. The second cover member 22 has a pair of second locking receiving portions formed in mirror symmetry with respect to a vertical plane extending forward and backward relative to the first locking receiving portions 211a, 211b of the first cover member 21 (see FIG. 3). The second cover member 22 is attached to the core material 11 with the second locking portions 132a, 132b fitted into the second locking receiving portions, respectively, and with the second locking portions 132a, 132b locked by the second locking receiving portions, respectively. In this attached state, the second cover member 22 is arranged so as to straddle the area between the right end of the front surface 121 and the front end of the right side surface 123 of the core material 11, which sandwich the second corner portion 112 therebetween.

[0034] The third cover member 23 is provided with a pair of third locking portions 133a, 133b that protrude from the rear surface 124 and the left side surface 122 of the core material 11 that sandwich the third corner portion 113, respectively. The third cover member 23 has a pair of third locking receiving portions formed in mirror symmetry with respect to a vertical plane extending left and right to the first locking receiving portions 211a, 211b of the first cover member 21 (see FIG. 3). The third cover member 23 is attached to the core material 11 with the third locking portions 133a, 133b fitted into the third locking receiving portions, respectively, and with the third locking portions 133a, 133b locked by the third locking receiving portions, respectively. In this attached state, the third cover member 23 is disposed so as to straddle the left end of the rear surface 124 and the rear end of the left side surface 122 of the core material 11 that sandwich the third corner portion 113 therebetween.

[0035] The fourth cover member 24 is provided with a pair of fourth locking portions 134a, 134b that protrude from the rear surface 124 and the right side surface 123 of the core material 11 that sandwich the fourth corner portion 114, respectively. The fourth cover member 24 has a pair of fourth locking receiving portions formed rotationally symmetrically with respect to the first locking receiving portions 211a, 211b of the first cover member 21, with the cross-sectional center of the core material 11 as the reference point (see FIG. 3). The fourth cover member 24 is attached to the core material 11 with the fourth locking portions 134a, 134b fitted into the fourth locking receiving portions, respectively, and with the fourth locking portions 134a, 134b locked by the fourth locking receiving portions, respectively. In this attached state, the fourth cover member 24 is disposed so as to straddle the right end of the rear surface 124 and the rear end of the right side surface 123 of the core material 11 that sandwich the fourth corner portion 114 therebetween.

[0036] As shown in Figure 3, when each of the first, second, third and fourth cover members 21 to 24 is attached to the core material 11, a gap is formed between the first cover member 21 and the second cover member 22, and a portion of the side of the core material 11 sandwiched between the first corner portion 111 and the second corner portion 112, i.e., the front surface 121, is exposed through this gap. Similarly, a portion of the right side surface 123 of the core material 11 sandwiched between the second corner portion 112 and the fourth corner portion 114 is exposed between the second cover member 22 and the fourth cover member 24. A portion of the rear surface 124 of the core material 11 sandwiched between the fourth corner portion 114 and the third corner portion 113 is exposed between the fourth cover member 24 and the third cover member 23. And a portion of the left side surface 122 of the core material 11 sandwiched between the third corner portion 113 and the first corner portion 111 is exposed between the third cover member 23 and the first cover member 21.

[0037] Furthermore, when the first cover member 21 is attached to the core material 11 , the front facing surface 212 faces the left end of the front surface 121 , and the left facing surface 213 faces the front end of the left side surface 122 . The forward facing surface 212 and the left end of the front surface 121 are in contact with each other or face each other with a small gap therebetween. When the first cover member 21 translates in the front-to-rear direction D1 or rotates around the first corner 111 (clockwise rotation in FIG. 3 ), the forward facing surface 212 comes into contact with the left end of the front surface 121, thereby preventing the first cover member 21 from moving or rotating. Similarly, the left-facing surface 213 and the upper end of the left side surface 122 are in contact with each other or face each other with a small gap therebetween. When the first cover member 21 translates in the left-right direction D2 or rotates around the first corner 111 (counterclockwise rotation in FIG. 3 ), the left-facing surface 213 comes into contact with the upper end of the left side surface 122, thereby preventing the first cover member 21 from moving or rotating.

[0038] The same applies to the other cover members 22, 23, and 24. The second cover member 22 has an end face facing the right end of the front surface 121 of the core material 11 and an end face facing the upper end of the right surface 123, each of which abuts against the front surface 121 or the right surface 123, or faces the front surface 121 or the right surface 123 with a small gap between them. By abutting against the right end of the front surface 121, the second cover member 22 is prevented from moving in a translational manner in the fore-and-aft direction D1 and from rotating around the second corner 112, and by abutting against the upper end of the right side surface 123, the second cover member 22 is prevented from moving in a translational manner in the left-right direction D2 and from rotating around the second corner 112. Similarly, in the third cover member 23, abutment against the left end of the rear surface 124 prevents translational movement of the third cover member 23 in the fore-and-aft direction D1 and rotation around the third corner 113, and abutment against the lower end of the left side surface 122 prevents translational movement of the third cover member 23 in the left-right direction D2 and rotation around the third corner 113. Furthermore, the fourth cover member 24 abuts against the right end of the rear surface 124, thereby preventing the fourth cover member 24 from moving in the forward / backward direction D1 and from rotating around the fourth corner 114, and the fourth cover member 24 abuts against the lower end of the right surface 123, thereby preventing the fourth cover member 24 from moving in the left / right direction D2 and from rotating around the fourth corner 114.

[0039] In this embodiment, each of the cover members 21 to 24 is formed from a material different from that of the core material 11. An example of a material that can be used for the core material 11 is aluminum, and an example of a material that can be used for the cover members 21 to 24 is wood.

[0040] (Relationship between frame material and panel material) 2, the panel member 2 has protrusions 201a and 201b that protrude in the short direction on each of its longitudinal end faces (in this embodiment, on the end faces facing the left-right direction D2). The protrusions 201a and 201b are provided over the entire panel member 2 in the longitudinal direction. The panel member 2 is fastened to the frame member 1A with the protruding portions 201a and 201 disposed in the gaps formed between the cover members 21 to 24, respectively. Specifically, one protrusion 201a is positioned in the gap between the second and fourth cover members 22, 24 of one of the pair of frame members 1A that sandwich the panel member 2, and the other protrusion 201b is positioned in the gap between the first and third cover members 21, 23 of the other frame member 1A. Here, the front surface 121 of the core material 11 and one surface of the panel member 2 face in the same direction (i.e., forward), and the rear surface 124 of the core material 11 and the other surface of the panel member 2 face in the same direction (i.e., backward).

[0041] (Explanation of action and effect) The effects obtained by this embodiment will be described below. By configuring the frame material 1A separately into a core material 11 and cover members 21-24 and making it possible to attach the cover members 21-24 to the core material 11, the strength of the frame material 1A is ensured by the core material 11, while the cover members 21-24 protect the core material 11, and at the same time, it is possible to achieve greater freedom in terms of exterior design.

[0042] By providing a first cover member 21 and a second cover member 22, with the first cover member 21 covering the first corner 111 of the core material 11 and the second member 22 covering the second corner 112 of the core material 11, it is possible to paint or decorate the first cover member 21 and the second cover member 22 in different colors, and to achieve a harmonious appearance with other members (in this embodiment, panel member 2) that are connected to sandwich the frame material 1A. Furthermore, if deterioration or damage occurs to the first cover member 21 or the second cover member 22, it is sufficient to replace only the area of ​​the member where deterioration or damage has occurred, which makes it possible to reduce the effort and cost required for replacement work.

[0043] Furthermore, by configuring the core material 11 so that a portion of its side surface is exposed between the first cover member 21 and the second cover member 22, the weight of the entire frame material 1A can be reduced while the side surfaces of the core material 11, in this embodiment the front surface 121 and rear surface 124 which face in the same direction as the surface of the panel member 2, function as additional design surfaces, making it possible to accommodate further diversification of designs. As described above, according to this embodiment, it is possible to provide a highly functional and convenient frame material 1A.

[0044] In addition to the above, the core material 11 is provided with a pair of first locking portions 131a, 131b protruding from each of a pair of side surfaces 121, 122 that sandwich the first corner portion 111, and the first cover member 21 is provided with a pair of first locking receiving portions 211a, 211b that respectively receive the pair of first locking portions 131a, 131b. This makes it possible to suppress shifting of the first cover member 21 in the cross-sectional direction and to securely attach the first cover member 21 to the core material 11.

[0045] The same applies to the other cover members 22 to 24, and it is possible to prevent the second, third and fourth cover members 22 to 24 from shifting in the cross-sectional direction and to attach them to the core material 11 securely.

[0046] A pair of end portions or end faces formed on the first cover member 21, in this embodiment the front facing surface 212 and the left facing surface 213, are abutted against the opposing side surfaces 121, 122 of the core material 11, thereby preventing rotation of the first cover member 21 relative to the first corner portion 111, thereby making it possible to attach the first cover member 21 to the core material 11 in a more stable state. The same is true for the other cover members 22-24; by preventing the second, third and fourth cover members 22-24 from rotating about the corners 112-114, these cover members 22-24 can be attached to the core material 11 in a more stable state.

[0047] By covering the four corners of the core material 11 having a rectangular cross section, i.e., the first corner 111 to the fourth corner 114, with the cover members 21 to 24, it is possible to give the appearance of the frame material 1A a sense of unity and uniformity. Furthermore, it is possible to effectively protect the corners 111 to 114 of the core material 11 from external interference.

[0048] The first and second cover members 21, 22, and in this embodiment, the four cover members 21 to 24 are all formed from a material different from the core material 11, making it possible to select and use appropriate materials for each of the core material 11 and the cover members 21 to 24.

[0049] By forming the core material 11 from aluminum, the strength of the core material 11 is ensured and the weight of the entire frame material 1A is reduced, and by forming the cover members 21 to 24 from wood, it is possible to give the appearance and texture of the frame material 1A the warmth of wood.

[0050] (First Modification) As shown in Figure 5, the frame material 1B of the first variant of this embodiment includes, as cover members, a first cover member 31 that covers the first corner portion 111 and the third corner portion 113 of the core material 11, and a second cover member 32 that covers the second corner portion 112 and the fourth corner portion 114. That is, in this embodiment, two cover members, that is, first and second cover members 31 and 32, are provided, and these two cover members 31 and 32 are configured to cover two corner portions, respectively. The core material 11 has a configuration similar to that shown in Figure 4(a), and is roughly lattice-shaped in cross section, with a pair of locking portions (for example, a pair of first locking portions 131a, 131b for the first corner portion 111) provided at each of the four corner portions 111 to 114.

[0051] The first cover member 31 extends between the left end of the front surface 121 and the left end of the rear surface 124 so as to straddle the first corner 111 and the third corner 113. The first cover member 31 has a pair of first locking receiving portions into which the first locking portions 131a, 131b are respectively fitted, and a pair of third locking receiving portions into which the third locking portions 133a, 133b are respectively fitted. When the first cover member 31 is attached to the core material 11, the first locking portions 131a, 131b and the second locking portions 133a, 133b are fitted into and locked into the corresponding locking receiving portions.

[0052] The same is true for the second cover member 32, which extends between the right end of the front surface 121 and the right end of the rear surface 124 so as to straddle the second corner 112 and the fourth corner 114. The second cover member 32 has a pair of second locking receiving portions and a pair of fourth locking receiving portions, and when attached to the core material 11, the second locking portions 132a, 132b and the fourth locking portions 134a, 134b each fit into and lock into the corresponding locking receiving portions.

[0053] Between the first cover member 31 and the second cover member 32, a part of the front surface 121 is exposed, and a part of the rear surface 124 is exposed. In contrast, in this embodiment, the first cover member 31 covers the entire left side surface 122 of the core material 11, and the first cover member 31 forms a continuous left side surface of the frame material 1B. Similarly, the second cover member 32 covers the entire right side surface 123 of the core material 11, and the second cover member 32 forms a continuous right side surface of the frame material 1B.

[0054] In this way, by covering two adjacent corners of the core material 11 (for example, the first and third corners 111, 113 adjacent to each other in the front and rear) with the first cover member 31 and covering the other two corners (the second and fourth corners 112, 114) with the second cover member 32, it is possible to realize a design that suits the use of the frame material 1B. For example, it is possible to provide the option of placing cover members 31, 32 on the entire side (e.g., left and right sides) of frame material 1B that is visible to people or users, making it possible to give a different impression in appearance from the sides where part of core material 11 is exposed, i.e., the front surface 121 and rear surface 124.

[0055] (Second Modification) As shown in FIG. 6, a frame material 1C according to a second modified example of this embodiment differs from the example shown in FIG. 3 in both the core material 11' and the cover members 41 and 42. The frame material 1C includes a core material 11' and two cover members 41, 42. That is, similar to the first modified example, the four corners 111 to 114 are divided into two groups of two, and the corners of each group are covered by two cover members 41, 42, respectively. Specifically, the first and third corners 111, 113 are covered by the first cover member 41, and the second and fourth cover members 112, 114 are covered by the second cover member .

[0056] As shown in FIG. 7(a), the core 11' includes a main body 141 having a cross-shaped cross section, and a plurality of locking portions 151 to 154 protruding from each side surface of the main body 141. The core material 11' has, as the engaging portions 151 to 154, a pair of first engaging portions 151a, 151b protruding from the left end portion of the front surface 121 and the front end portion of the left side surface 122, respectively, a pair of second engaging portions 152a, 152b protruding from the right end portion of the front surface 121 and the front end portion of the right side surface 123, respectively, as well as a third engaging portion 153 protruding from the rear end portion of the left side surface 122 and a fourth engaging portion 154 protruding from the rear end portion of the right side surface 123.

[0057] In addition to the above, core material 11' has a portion of rear surface 124 removed, leaving the interior surrounded on three sides by front surface 121 and left and right side surfaces 122, 123 open toward the rear. Core material 11' has a diagonal brace 142 spanning between left side surface 122 and right side surface 123 to prevent a decrease in strength due to the removal of rear surface 124. The core material 11' has extension portions 143a, 143b that extend outward in the front-to-rear direction D1, i.e., rearward, from the left and right edges that define the cutout portion of the rear surface 124, and has tip hook-shaped portions 144a, 144b at the tip of each of these pair of extension portions 143a, 143b. The pair of extension portions 143a, 143b have mirror-symmetric shapes, are bent in directions away from each other from a base end portion 1431 extending rearward from the main body portion 141, and each form an L-shape as a whole. The distal hook portions 144a, 144b are connected in a hook shape to the distal ends of the extension portions 143a, 143b. In each of the extension portions 143a, 143b, the base end portion 1431 and the distal hook portions 144a, 144b face each other and are parallel to each other, and a portion of the cover members 41, 42 is received between the base end portion 1431 and the distal hook portions 144a, 144b.

[0058] As shown in FIG. 7(b), the first cover member 41 has a notch n21 that fits the outer shape of one side portion of the main body portion 141 (the left half portion in the state shown in FIG. 7(a)). The first cover member 41 has inner surfaces facing rearward, rightward, and forward due to the formation of the notch n21, and is formed with first locking receiving portions 411a, 411b that open to the upper end of the inner surface facing rearward and the inner surface facing rightward, respectively, and a third locking receiving portion 413 that opens to the lower end of the inner surface facing rightward. Similarly, the second cover member 42 has a notch n22 that fits the outer shape of the other side portion (the right half portion in the state shown in FIG. 7(a)) of the main body portion 141, and the formation of the notch n22 gives it inner surfaces facing rearward, leftward, and forward. The second cover member 42 is formed with second locking receiving portions 412a, 412b that open at the upper end of the inner surface facing rearward and the inner surface facing leftward, respectively, and a fourth locking receiving portion 414 that opens at the lower end of the inner surface facing leftward. The first, second, third and fourth locking portions 411-414 are all groove-shaped and extend in one direction along which the core 11' extends. The locking portions 411-414 receive and lock the corresponding engaging portions 151-154 among the first, second, third and fourth engaging portions 151-154.

[0059] The first cover member 41 and the second cover member 42 each have end surface recesses 415a, 415b that engage with the tip hook portions 144a, 144b. As shown in Fig. 6, the end surface recesses 415a, 415b receive and lock the corresponding tip hook portions 144a, 144b of the pair of tip hook portions 144a, 144b provided on the core material 11'. With the tip hooks 144a, 144b locked by the end surface recesses 415a, 415b, parts of the cover members 41, 42 are interposed between the rear surface 124 of the core 11' and the extensions 143a, 143b (see FIG. 6). In this embodiment, the elasticity of the extensions 143a and 143b made of aluminum is used to press the parts of the cover members 41 and 42 appropriately against the rear surface 124, and the cover members 41 and 42 are sandwiched between the main body 141 and the extensions 143a and 143b.

[0060] In this way, by covering the two adjacent corners 111, 113 of the core material 11 with the first cover member 31 and the other two corners 112, 114 with the second cover member 32, it is possible to realize a design that suits the use of the frame material 1B, as in the first modified example described above. Furthermore, extensions 143a, 143b are formed on the core material 11', and the tip hook portions 144a, 144b connected to the tip side thereof are engaged with the end surface concave portions 415a, 415b of the cover members 41, 42, and by clamping parts of the cover members 41, 42 between the extensions 143a, 143b and the main body portion 141, it is possible to securely attach the cover members 41, 42 to the core material 11' and effectively prevent the cover members 41, 42 from falling off.

[0061] (Second embodiment) 8, a frame material 1D according to the second embodiment of the present invention, like the first embodiment, comprises, as its main components, a core material 11 and four cover members 51 to 54. In this embodiment, the core material 11 and the cover members 51 to 54 are formed from the same material, specifically, aluminum.

[0062] As shown in Figure 9(a), the core material 11 has the same configuration as that shown in Figure 4(a), and is roughly lattice-shaped in cross section, with a pair of locking portions (for example, a pair of first locking portions 131a, 131b for the first corner portion 111) provided at each of the four corner portions 111 to 114.

[0063] The cover members 51 to 54 are individually attached to the first, second, third, and fourth corners 111 to 114. The cover members 51 to 54 have similar shapes, and by changing their orientation, they can be attached to any of the first to fourth corners 111 to 114. In other words, cover members of the same shape can be shared between the first to fourth corners 111 to 114.

[0064] When the cover members 51 to 54 are attached to the core material 11, the first cover member 51 located at the upper left of the paper in Figure 8 and the second cover member 52 located at the upper right have mirror-symmetrical shapes with respect to a vertical plane that passes through the center of the cross section of the core material 11 and extends in the front-to-back direction D1. Similarly, the first cover member 51 and the third cover member 53 located on the lower left have mirror symmetry with respect to a vertical plane that passes through the center of the cross section of the core material 11 and extends in the left-right direction D2. Furthermore, the first cover member 51 and the fourth cover member 54 located at the lower right have rotationally symmetric shapes with the center of the cross section of the core material 11 as the reference.

[0065] Here, between the cover members 51 to 54 adjacent to each other in the front-rear direction D1 or the left-right direction D2, a part of the side surfaces 121 to 124 of the core material 11 is exposed. Specifically, a portion of the front surface 121 is exposed between the first cover member 51 and the second cover member 52, and a portion of the rear surface 124 is exposed between the third cover member 53 and the fourth cover member 54. Furthermore, a portion of the left side surface 122 is exposed between the first cover member 51 and the third cover member 53, and a portion of the right side surface 123 is exposed between the second cover member 52 and the fourth cover member .

[0066] The first to fourth cover members 51 to 54 each have the same shape as a single unit. Hereinafter, the configuration of the cover members 51 to 54 according to this embodiment and the attachment structure to the core material 11 will be described based on FIG. 9, taking the first cover member 51 as a representative, with appropriate reference to FIGS. 10 and 11.

[0067] As shown in FIG. 9(b), the first cover member 51 has an outer shell portion 511 and a pair of first locking receiving portions 512a, 512b. The outer shell portion 511 forms the outer shell of the first cover member 51, and its outer shape matches the overall outer shape of the first cover member 51 itself. The outer shell portion 511 has a shape with a portion missing so that the first corner portion 111 is positioned inside the first cover member 51 when the first cover member 51 is attached to the core material 11. When the first cover member 51 is attached to the core material 11, the portion of the outer shell portion 511 other than the missing portion surrounds the first corner portion 111.

[0068] One of the first locking receiving portions 512a has a parallel extending portion 521 extending parallel to the first locking portion 131b protruding from the upper end of the left side surface 122, and a tip abutment receiving portion 522 and an intermediate abutment portion 523 protruding from the parallel extending portion 521 perpendicular to the first locking portion 131b. The tip abutment receiving portion 522 extends from one side of the parallel extending portion 521 facing the first locking portion 131b in a direction perpendicular to the first locking portion 131b, and as shown in Figure 11, the tip of the first locking portion 131b abuts in the protruding direction of the first locking portion 131b (toward the left in the state shown in the same figure). The intermediate contact portion 523 extends from the tip of the parallel extending portion 521 in a direction perpendicular to the first locking portion 131b, and as shown in FIG. 11, the tip of the intermediate contact portion 523 contacts the intermediate portion of the first locking portion 131b.

[0069] Here, an engaging portion f1 that engages with the tip of the first locking portion 131b and an engaging portion f2 that engages with the tip of the intermediate abutting portion 523 are formed at the tip of the tip abutting portion 522 and the intermediate portion of the first locking portion 131b, respectively. The engaging portion f1 at the tip of the tip abutting portion 522 restricts relative movement of the first locking portion 512a and the first cover member 51 in the front-to-rear direction D1 (e.g., forward) with respect to the core material 11. The first locking portion 131b has an intermediate engaging portion f2 that restricts the relative movement of the first locking receiving portion 512a and the first cover member 51 relative to the core material 11 in the left-right direction D2 (for example, leftward).

[0070] The other first locking receiving portion 512b has a vertical extending portion 524 extending perpendicular to the first locking portion 131a protruding from the left end of the front surface 121, and an intermediate engaging portion 525 protruding from the vertical extending portion 524 parallel to the first locking portion 131a. The intermediate engagement portion 525 extends from near the tip of the vertical extension portion 524 in a direction parallel to the first locking portion 131a, and has a hook-shaped portion f3 at its tip. Here, the first locking portion 131a has a protrusion p1 formed in its middle portion (see FIG. 9(a)), and as shown in FIG. 11, the tip hook-shaped portion f3 of the intermediate engagement portion 525 engages with the middle protrusion p1 of the first locking portion 131a, thereby restricting relative movement of the first lock receiving portion 512b and the first cover member 51 in the front-to-rear direction D1 (e.g., forward) with respect to the core material 11.

[0071] Here, the first locking portion 131a has a notch n3 at its tip (see Figure 9(a)), and this notch n3 forms an end face of the first locking portion 131a that faces in the same direction as the front surface 121 and an end face that faces the middle part of the front surface 121, perpendicular to the direction in which the front surface 121 faces. As shown in FIG. 11, the tip of the vertically extending portion 524 abuts against the end surface formed by the notch n3. This restricts the relative movement of the first lock receiving portion 512b and the first cover member 51 relative to the core material 11 in the left-right direction D2 (for example, leftward), and restricts the relative movement in the front-rear direction D1 (for example, rearward).

[0072] The first cover member 51 is attached to the core material 11 according to the procedure shown in FIG. 10(a), the first corner portion 111 of the core material 11 is inserted into the first cover member 51 through the missing portion of the first cover member 51 (specifically, the missing portion of the outer shell portion 511). At this time, the insertion of the first corner portion 111 can be achieved by slightly tilting the first cover member 51 in the front-to-back or left-to-right direction. Next, as shown in Figure 10(b), the orientation of the first cover member 51 is corrected and the first cover member 51 is positioned so that the parallel extending portion 521 is parallel to one of the first locking portions 131b and the vertical extending portion 524 is perpendicular to the other first locking portion 131a. Then, as shown in Figure 10(c), the first cover member 51 is moved in the front-to-back direction D1 (e.g., rearward) relative to the first corner portion 111, and the first locking portion 131a protruding from the front surface 121 is locked to one of the first locking receiving portions 512b, and the first locking portion 131b protruding from the left side surface 122 is locked to the other first locking receiving portion 512a. When the engaging portion f1 passes over the tip of the first locking portion 131b, the tip abutment receiving portion 522 is deformed due to the elasticity of the aluminum material. Similarly, when the tip hook-shaped portion f3 passes over the intermediate protruding portion p1 of the first locking portion 131a, the intermediate engaging portion 525 is deformed due to the elasticity of the aluminum material.

[0073] The same applies to the other cover members 52 to 54.

[0074] In this way, the cover members 51 to 54, for example the first cover member 51, are provided with a parallel extending portion 521 and a vertical extending portion 524, and the tip abutment receiving portion 522 and intermediate abutment portion 523 of the parallel extending portion 521 restrict relative movement of the first cover member 51 in the front-to-back and left-to-right directions D1, D2 relative to the first corner portion 111, and the vertical extending portion 524 and its intermediate engaging portion 525 restrict relative movement of the first cover member 51 in the front-to-back and left-to-right directions D1, D2 relative to the first corner portion 111, thereby making it possible to securely attach the first cover member 51 to the core material 11. Here, a recess is formed in the outer shell portion 511 of the first cover member 51, allowing the first corner portion 111 to be inserted into the inside from the side of the first cover member 51 through this recess, and the tip abutment receiving portion 522 and the intermediate engagement portion 525 are made elastically deformable, so that the first cover member 51 can be attached to the core material 11 from the side, in other words, from a direction perpendicular to the direction in which the first corner portion 111 extends. This effect is more pronounced when the first corner 111 is divided into multiple regions across its entirety and each region is covered by a first cover member 51, rather than covering the entire first corner 111 with one or a single first cover member 51, making it possible to achieve good attachment to the core material 11.

[0075] (Third embodiment) 12, the frame material 1 used in the partition P' according to the third embodiment of the present invention may be any of the frame materials 1A to 1D according to the first embodiment (including the first and second modifications) and the second embodiment described above. As an example, a case where the frame material 1D according to the second embodiment is used will be described.

[0076] The partition P' according to this embodiment includes a plurality of panel members 2. Figure 12 shows three of the plurality of panel members 2. The number of panel members 2 used in the partition P' may be three in total, or may be more than three. The panel members 2 are rectangular in front view, and are arranged side by side with their longitudinal directions aligned vertically and their short-side end faces facing each other. Frame members 1D are interposed between adjacent panel members 2, and the panel members 2 are connected via the frame members 1D. 2, the panel member 2 has protrusions 201a, 201b that protrude in the short direction on each of its longitudinal end faces. The panel member 2 is fastened to the frame material 1D with the protrusions 201a, 201b positioned in the gaps between the cover members 21-24.

[0077] In this embodiment, as shown in Figure 13, the side of the core material 11 of the frame material 1D that faces in the same direction as the surface of the panel member 2 (2A, 2B) is painted in a different color or has a different pattern than at least one of the pair of cover members 51, 52 attached to the corners located on both edges of this side. 13(a) to 13(c) show an enlarged view of the range R indicated by the two-dot chain line in FIG. The surfaces of the panel members 2A and 2B and the front surface 121 of the core material 11 face in the same direction, and the paint or pattern of the front surface 121 is made different from that of at least one of the first cover member 51 and the second cover member 52 attached to the left and right corners, i.e., the first and second corners 111 and 112 located on the edge of the front surface 121. The panel members 2A and 2B are then painted in the same color or with the same pattern as the cover members 51 and 52 to which they are connected.

[0078] In the example shown in Figure 13(a), the front surface 121, the first cover member 51, and the second cover member 52 are each painted in a different color, while the first cover member 51 and the panel member 2A connected to it are painted in the same color, and the second cover member 52 and the panel member 2B connected to it are painted in the same color. That is, the front surface 121, the first cover member 51, and the second cover member 52 of the partition P' are painted in three colors or three kinds of paint.

[0079] 13(b), the first cover member 51 and the second cover member 52 are painted in the same color, while the front surface 121 is painted in a color different from that of either the first or second cover member 51, 52. As described above, the first cover member 51 and the panel member 2A connected thereto are painted in the same color, and the second cover member 52 and the panel member 2B connected thereto are painted in the same color. That is, the front surface 121 and the first and second cover members 51, 52 of the partition P' are painted in two colors or two types of paint.

[0080] 13(c), the first cover member 51 and the second cover member 52 are painted in different colors, and the front surface 121 is painted in the same color as one of the first and second cover members 51, 52 (for example, the second cover member 52). The first cover member 51 and the panel member 2A connected thereto are painted in the same color, and the second cover member 52 and the panel member 2B connected thereto are painted in the same color. It is also possible to partially paint a part of the first cover member 51 or the second cover member 52 in a color different from the base color, in other words, to apply a color scheme 51r that serves as an accent color. The accent color scheme 51r is not limited to the cover members 51 and 52, but can also be applied to the panel members 2A and 2B. In this way, by painting the core material 11 in a color different from at least one of the first cover member 51 or the second cover member 52, that is, by color-coding the core material 11 and the cover members 51, 52, it is possible to achieve greater freedom in terms of exterior design.

[0081] Furthermore, by painting the first cover member 51 and the second cover member 52 in different colors, if the panel members 2A and 2B arranged on either side of the frame material 1D are different colors on the left and right, the first and second cover members 51 and 52 can be painted in colors that match the respective panel members 2A and 2B, making it possible to harmonize the appearance of the entire partition P'.

[0082] The panel member 2 that constitutes the partition P' does not have to be a single piece across the entire vertical direction, but can also be formed by stacking multiple panel members 2 vertically and sandwiching these multiple panel members 2 between frame materials 1 on both sides. The frame material 1 may be any of the frame materials 1A to 1D according to the first and second embodiments, and FIG. 14 shows, as an example, a case in which the frame material 1D according to the second embodiment is used.

[0083] 14, the partition P' includes three stacked panel members 2, and each set of three panel members 2 is arranged side by side with one surface facing forward. The number of panel members 2 is not limited to this, and may be two, four or more. A frame member 1D is placed between adjacent pairs of panel members 2, and the panel members 2 are connected to and supported by each other in the same manner as shown in FIG. The frame material 1D supporting adjacent pairs of panel members 2 does not need to be integral over the entire vertical direction, and can be divided into multiple pieces. For example, the length or height dimension of one frame material 1D is made to match the height dimension of the panel member 2, and it is arranged to correspond to each panel member 2, and frame materials 1D that abut each other vertically are joined in their longitudinal direction.

[0084] In the frame material 1D, the painting or decoration applied to the side surface (for example, the front surface 121) of the core material 11 and the cover members 51, 52 may be any of the forms shown in Figs. 13(a) to 13(c). 14 shows a case in which the front surface 121 of the core material 11, the first cover member 51, and the second cover member 52 are painted in different colors, similar to the case shown in Fig. 13(a). The first cover member 51 and the panel member 2 connected thereto are painted in the same color, and the second cover member 52 and the panel member 2 connected thereto are also painted in the same color. 14, adjacent and overlapping panel members 2 are painted in different colors or have different decorations. For example, when the entire partition P' is viewed from the front, it has a staggered appearance or pattern.

[0085] In this way, the core material 11 and the cover members 51, 52 are color-coded, and the first and second cover members 51, 52 are painted in colors that match the panel members 2 that connect to them.In addition, the panel members 2 that overlap one another vertically and the panel members 2 that are lined up on the left and right have different paint colors or decorations, which makes it possible to achieve a greater degree of freedom in the exterior design of the entire partition P'.
