Description

Technical Field

[0001] This invention relates to a panel material for partitioning that has a bulletin board function on each entire surface of one side or both sides.

Background Art

[0002] There is known a bulletin board that has both a pin-up function of fixing a posted item with a thumbtack and a magnet function of fixing a posted item with a magnet piece (for example, Patent Document 1).

[0003] A conventional bulletin board is configured by laminating a surface material of a punching steel plate via a pin support material of a soft synthetic resin sheet material on one side of a core material made of a particle board. A common peripheral frame whose outer peripheral surface bulges in an arc shape in cross section is attached around the core material, the pin support material, and the surface material. Therefore, if a thumbtack is pierced through the hole of the surface material and supported by the pin support material, the pin-up function by the thumbtack can be realized, and if a magnet piece is adsorbed on the surface material, the magnet function by the magnet piece can be realized.

Summary of the Invention

Problems to be Solved by the Invention

[0005] According to such a conventional technique, since the bulletin board is assumed to be used by hanging it on a wall surface or the like, the posting surface is limited to one side, and there is a problem that it is not always easy to meet the requirement of a large posting surface. In recent years, in school facilities, partitioning devices have been introduced to partition indoor spaces such as classrooms, and moreover, there is often a need for a large posting surface for displaying and posting works of children and students.

[0006] Therefore, in view of the problems of the prior art, the object of this invention is to provide a partition panel material that can easily meet the demands of school facilities in recent years by having a bulletin board function on the entire surface of one or both sides. [Means for solving the problem]

[0007] The gist of the invention of claim 1, which achieves the above objective, is that it comprises a paper honeycomb core material, a perforated steel sheet surface material laminated on at least one side of the core material via a backing material, and an edge material common to the core material, backing material, and surface material, wherein the backing material can be supported by inserting a thumbtack through the holes in the surface material, and the edge material is formed in the shape of a rectangular frame, with two opposing sides having a substantially hat-shaped cross-section and outward-facing grooves formed on the outer circumferential surface, and the other two sides having a channel-shaped cross-section and a flat outer circumferential surface.

[0008] The gist of the invention of claim 2 is that it comprises a paper honeycomb core material, a perforated steel sheet surface material laminated on at least one side of the core material via a backing material, and an edge material common to the core material, backing material and surface material, wherein the backing material can be supported by inserting thumbtacks through holes in the surface material, and the edge material is formed in the shape of a rectangular frame, with a channel cross-section on all sides and a planar outer surface.

[0009] The backing material can be made of wood.

[0010] Furthermore, the edge material may be combined with a reinforcing material that has a channel-shaped cross-section, or it may be positioned via a backing material. [Effects of the Invention]

[0011] According to the inventions of claims 1 and 2, the backing material and surface material laminated on one or both sides of the core material can have a bulletin board function on each of its entire surfaces, including a pin-up function using thumbtacks, a magnetic function using magnetic pieces, and a tape-attaching function for fixing posted items with adhesive tape such as cellophane tape.

[0012] The core material is a core material for sandwich structures such as doors, partitions, and flush panels, formed by continuously molding and laminating corrugated cardboard core paper in a corrugated shape, for example, with a cell size of 10.5 mm and a compressive strength of 2.1 kgf / cm². 2 , density 33kg / m 3 A thickness of approximately 30 mm is preferable. The backing material can be any board material that can be supported by inserting thumbtacks through it with your fingers, such as ordinary plywood (shear strength 0.7 MPa, thickness approximately 4 mm) such as lauan, or wood-based materials such as veneer-backed strand board, particleboard, MDF, or synthetic resin boards such as polystyrene foam or corrugated cardboard.

[0013] The surface material is a perforated steel plate with a thickness of approximately 0.5 to 0.6 mm, in which, for example, round holes with a diameter of 3 to 10 mm are formed all over the surface with an opening ratio of approximately 5 to 15%, and then appropriately painted. If the hole diameter or opening ratio is too large, it may impair the adhesive strength of the pressure tape or the attractive force of the magnet pieces, and if the hole diameter or opening ratio is too small, it may make it difficult to fix posted items with thumbtacks. The holes in the perforated steel plate may be of any shape other than round holes, such as square holes or cross-shaped holes, and two or more types of holes may be mixed, and the arrangement format may also be arbitrary.

[0014] The trim material, which has a roughly hat-shaped cross-section, can form outward-facing grooves on its outer surface. Therefore, if the trim material with a roughly hat-shaped cross-section is placed on the top and bottom sides of the panel material, for example, the upper rail on the ceiling side and the lower rail on the floor side can be engaged with the grooves on the top and bottom, respectively, to stably erect the panel material. If it is placed on the left and right sides of the panel material, for example, a common support column can be housed between the grooves on each side and the grooves of adjacent panel materials, allowing the panel materials to be connected and erected in a horizontal row.

[0015] The edge material in the shape of a cross-sectional channel forms a flat outer peripheral surface, and each flange can achieve appropriate dimensions and present a regular appearance. Note that the edge material in a substantially hat-shaped cross-section can form auxiliary flanges by bending the tips of the left and right outer flanges of the hat shape at 90° in the hat direction, and can achieve dimensions equivalent to those of the edge material in the shape of a cross-sectional channel.

[0016] The backing material for the woody material has advantages such as being excellent in the ease of piercing the pins of the picture nails and supportability, and being lightweight and easy to achieve appropriate rigidity.

[0017] The edge material is combined with a reinforcing material in the shape of a cross-sectional channel. For example, by sandwiching the peripheral edge of the backing material between the edge material and the reinforcing material, the backing material can be reliably positioned in the prospective direction through the backing material, and the peripheral edge of the panel material can be properly finished.

Embodiments for Carrying Out the Invention

[0019] Hereinafter, embodiments of the invention will be described with reference to the drawings.

[0020] The panel material 10 for partitioning is formed by laminating the surface materials 13 on both sides of the core material 11 via the backing materials 12 respectively, and attaching the edge materials 15, 15, 16, 16 to each of the upper, lower, left, and right sides (FIGS. 1 and 2). The edge materials 15, 15, 16, 16 are formed in a rectangular frame shape as a whole. However, FIGS. 2(A) and (B) are enlarged cross-sectional views of the main parts corresponding to the views in the directions of the arrows X1 - X1 and X2 - X2 in FIG. 1 respectively, and FIGS. 2(C) and (D) are enlarged cross-sectional views of the main parts corresponding to the views in the directions of the arrows Y1 - Y1 and Y2 - Y2 in FIG. 1 respectively.

[0021] The core material 11 is a paper honeycomb, the backing material 12 is, for example, a lauan ordinary plywood, and the surface material 13 is a punching steel plate. Circular holes 13a, 13a... are formed on the entire surface of the surface material 13 and arranged in a 45° stagger pattern. The hole diameter of the holes 13a is, for example, 5 mm, and the pitches a = b = 20 mm, c = d = 10 mm, and the aperture ratio is set to 9.8%. Each peripheral edge portion of the surface material 13 is bent inward along the peripheral end surface of the backing material 12.

[0022] The two left and right edge materials 16, 16 are each formed in a channel cross-section (FIGS. 2(A) and (B)), and together with the inward reinforcing material 16a in the channel cross-section, they are commonly attached to the core material 11, the backing materials 12, 12, and the surface materials 13, 13 via the fixing screws 16b. Each flange of the reinforcing material 16a is inserted between the core material 11 and each backing material 12, and each flange of the edge material 16 covers the peripheral edge portion of each surface material 13, realizes a predetermined dimension, and forms the outer peripheral surface in a planar shape. The outer dimension in the width direction of the reinforcing material 16a coincides with the thickness of the core material 11. Also, the edge material 16 sandwiches the peripheral edge portion of each backing material 12 together with the surface material 13 between it and the reinforcing material 16a, and is positioned via the backing materials 12, 12 and restrained in the expected direction.

[0023] The upper and lower edge members 15, 15 are each formed in a roughly hat-shaped cross-section (Figures 2(C), (D)), and together with the outward-facing reinforcing member 15a, which has a channel-shaped cross-section, they are attached to the core material 11, backing members 12, 12, and surface materials 13, 13 via set screws 15b, embedded between the backing members 12, 12. The edge member 15 has its left and right outer flanges 15c, 15c bent at 90° in the hat direction to form auxiliary flanges 15d, 15d, and each auxiliary flange 15d provides the same visible dimension as the edge member 16, while also forming outward-facing grooves 15e on its outer surface. The tips of each flange of the reinforcing member 15a coincide with the circumferential edge of the backing member 12. Furthermore, the outer width of the reinforcing member 15a matches the thickness of the core material 11, and the height of each flange matches the height of the hat section of the edge member 15. The edge material 15 is positioned in the depth direction via the backing materials 12, 12 by sandwiching the peripheral edge of the backing material 12 together with the surface material 13 between each auxiliary flange 15d and the reinforcing material 15a.

[0024] The panel material 10 can be erected on the floor F via a lower rail 21 on the floor F side and an upper rail 23 attached to the horizontal member 23a on the ceiling side (Figure 3). The lower rail 21 and upper rail 23 are engaged with the grooves 15e of the lower and upper edge members 15, respectively. The lower rail 21 is also fixed to the floor F via anchor bolts 21a. An adjuster 22 is housed in the lower rail 21, and the height of the panel material 10 can be adjusted via the adjuster bolts 22a of the adjuster 22.

[0025] The panel material 10 erected on the floor F can be used as a partition itself. Furthermore, the panel material 10, through the surface material 13 and backing material 12 on both sides, can function as a bulletin board with pin-up, magnetic, and tape-attachment capabilities, and can be used for displaying and posting any kind of notice. Other Embodiments

[0026] The panel material 10 can have a roughly hat-shaped edge material 15 attached to its left and right sides, and a channel-shaped edge material 16 attached to its top and bottom sides. In this case, the panel material 10 can be erected by connecting it to other adjacent panel materials 10 of the same type in a horizontal line via a common rectangular support column 24 (Figure 4). That is, approximately half of the support column 24 is engaged with the groove 15e of the edge material 15 of one panel material 10, and the other half of the support column 24 is engaged with the groove 15e of the edge material 15 of the other panel material 10, thereby forming predetermined joints 24a, 24a on both sides of the support column 24.

[0027] Therefore, the edge members 15, 15 can be attached to two opposing sides of the panel material 10, and the edge members 16, 16 can be attached to the other two sides (Figures 3 and 4).

[0028] The panel material 10 can be formed in a single-sided shape by laminating a surface material 13 onto one side of a core material 11 via a backing material 12 (Figure 5). However, Figures 5(A) to 5(D) correspond to Figures 2(A) to 5(D), respectively.

[0029] A backing material 14, for example, a steel plate or perforated steel plate with a thickness of about 0.5 to 0.6 mm, is attached to the other side of the panel material 10. The peripheral edges of the backing material 14 are bent inward in a symmetrical manner with the peripheral edges of the surface material 13.

[0030] The inward-facing reinforcing member 16a on the edge member 16 side has one flange inserted between the core member 11 and the backing material 14 (Figures 5(A), (B)), and the other flange inserted between the core member 11 and the backing material 12. The outward-facing reinforcing member 15a on the edge member 15 side has one flange in contact with the back surface of the backing material 14 (Figures 5(C), (D)), and the other flange is sandwiched between the hat portion of the edge member 15 and the backing material 12. The set screws 15b that fix the edge member 15 and the reinforcing member 15a are located at the center in the thickness direction of the core member 11, i.e., at the center of the reinforcing member 15a, but are offset from the centers of the panel material 10 and the edge member 15. The edge members 16 and 15 are positioned in the depth direction via the backing material 12 by being combined with the reinforcing members 16a and 15a, respectively.

[0031] The single-sided panel material 10 can be erected via a lower rail 21 housing an adjuster 22 and an upper rail 23, similar to the double-sided panel material 10 in Figure 3, by attaching edge materials 15, 15 to the top and bottom edges (Figure 6). Furthermore, the single-sided panel material 10 can be erected by connecting them in a horizontal line via support columns 24, similar to the double-sided panel material 10, 10 in Figure 4, by attaching edge materials 15, 15 to the left and right edges (not shown).

[0032] Furthermore, by attaching channel-shaped edge members 16 to all sides of the double-sided or single-sided panel material 10, it can be conveniently applied to standalone uses such as hanging or partition types. Alternatively, the panel material 10 may be fitted with roughly hat-shaped edge members 15 to all sides. [Industrial applicability]

[0033] This invention, while being a partition panel material, possesses a bulletin board function on both sides or the entire surface of one side, making it particularly suitable for applications requiring a large display area, such as school facilities. [Explanation of symbols]
