This disclosure relates to a structure to be attached to a board surface.

Conventionally, decorative panels are known for their use in attaching to surfaces such as interior walls and the sides of furniture, as disclosed in Patent Document 1. To facilitate the attachment and removal of such panels, adhesive mounting materials such as double-sided tape, or magnetic mounting materials such as magnets, are typically used depending on the material of the mounting surface.

Design Registration No. 1547707 Gazette

To attach a panel to a board surface in a detachable manner using the mounting components described above, the panel must be attached to the board surface with sufficient force to prevent it from detaching due to its own weight, while still being easily removable. Therefore, the material of the mounting components should be appropriately selected according to the material of the board surface, the material of the panel, etc., and the size should be determined to ensure sufficient mounting strength.

To stably mount the panel disclosed in Patent Document 1, it is necessary to properly position mounting members of various sizes. However, conventional methods for mounting such panels have not taken this proper positioning into consideration.

This disclosure aims to enable proper positioning of components for attaching a panel-like structure to a board surface, regardless of the size of the component.

To solve the above problems, a structure according to one aspect of this disclosure comprises a panel body having an adhesive surface to be attached to a board surface, and an adhesive member provided on the adhesive surface for detachably attaching the panel body to the board surface. The adhesive surface is provided with a positioning portion formed to protrude from the adhesive surface along its outer shape, and the adhesive member is positioned at a location determined by the positioning portion.

According to one aspect of this disclosure, the positioning of a component for attaching a panel-like structure to a board surface can be properly performed regardless of the size of the component.

<Structure>
(Overall structure)
As shown in Figures 1 to 4, the structure 1 comprises a panel unit 2 and an adhesive member 3. The panel unit 2 is attached to the surface 100a of the wall 100 by the adhesive member 3. The surface 100a is not limited to the wall 100, but may be the surface of a screen, partition, glass window, glass door, etc. The surface 100a is formed flat so that it can be attached by the adhesive member 3.

The panel unit 2 comprises a closing member 4 and a partitioning member 5. The panel unit 2 is constructed by joining the closing member 4 and the partitioning member 5. The closing member 4 and the partitioning member 5 are formed by molding resin, metal (especially aluminum), etc. However, the materials used to form the closing member 4 and the partitioning member 5 are not limited to the materials mentioned above.

If the blocking member 4 and the partitioning member 5 are made of resin, they may be light-transmitting. This ensures sufficient brightness in the area where the panel unit 2 is attached to the board surface 100a.

(Partitioning member)
The partitioning member 5 is a member whose interior is divided into multiple regions. The partitioning member 5 has a bottom wall 51, side walls 52, and multiple partition walls 53. The bottom wall 51 (panel body), side walls 52, and partition walls 53 are formed integrally.

The bottom wall 51 has a regular hexagonal shape. The shape of the bottom wall 51 is not limited to a regular hexagon; it can be any polygon, including shapes other than polygons, such as circles or ellipses. The bottom wall 51 has an inner surface 51a and an outer surface 51b. The outer surface 51b constitutes an adhesive surface that is detachably attached to the plate surface 100a by the adhesive member 3. The outer surface 51b is provided with a positioning portion 51c for positioning the adhesive member 3. The positioning portion 51c will be described in detail later.

The side walls 52, like the bottom wall 51, have a polygonal (regular hexagonal) shape and are provided around the outer periphery of the inner surface 51a, rising almost perpendicularly to the inner surface 51a. The side walls 52 have a constant width (height) and are formed continuously without interruption.

The partition wall 53 demarcates the area enclosed by the bottom wall 51 and the side walls 52. Specifically, the partition wall 53 divides this area into six triangular prism-shaped regions. However, the shape of the regions demarcated by the partition wall 53 is not limited to triangular prisms, nor is the number of such regions limited to six.

One end of partition wall 53 is connected to the corner of the side wall 52, and the other end of partition wall 53 is connected to the other ends of all other partition walls 53. The point where the other ends of partition walls 53 connect is offset from the center of the base wall 51, which forms a regular hexagon, but it could also be at the center of the base wall 51. Furthermore, the height of the other end of partition wall 53 is higher than the height of one end of partition wall 53.

(Blocking member)
The closing member 4 is a member that closes off the partitioned area of the partitioning member 5. The closing member 4 has a closing wall 41 and a side wall 42. The closing wall 41 and the side wall 42 are formed integrally.

The closing wall 41 has a regular hexagonal shape, which is the shape formed by the upper ends of the side walls 52. The external shape of the closing wall 41 is not limited to a regular hexagon; any polygon is acceptable as long as it matches the shape formed by the upper ends of the side walls 52. Other shapes, such as circles or ellipses, are also acceptable. Furthermore, the closing member 4 includes multiple triangular sections approximately the same size as the triangle formed by the upper ends of two adjacent partition walls and the upper end of a portion of the side wall 52 positioned between one end of the partition wall, forming the shape of an open umbrella. Note that the shape of the closing member 4 is not limited to a three-dimensional shape. Since the shape of the closing member 4 is determined according to the shape of the partition wall 53, it will be flat if the partition wall 53 has a certain height.

The side wall 42, like the side wall 52, has a polygonal (regular hexagonal) outer shape and is provided on the outer circumference of the inner surface of the side wall 42, that is, the surface facing the inner surface 51a of the bottom wall 51. The side wall 42 has a constant width (height) and is formed continuously without interruption. By being joined to the side wall 52, the side wall 42 together with the side wall 52 forms the side wall of the panel unit 2.

The closing member 4 is joined to the partition member 5 at the side wall 42 using adhesive or the like. By joining the closing member 4 to the partition member 5 without any gaps, it closes off the area partitioned by the partition wall 53.

<Adhesive structure>
(Positioning section)
As shown in Figures 2, 5, and 6, the positioning portion 51c is provided for positioning the adhesive member 3. The positioning portion 51c is a projection that extends from the outer surface 51b along the outer shape of the outer surface 51b, at a position slightly inward from the outer edge of the outer surface 51b. In the example shown in Figure 2, the positioning portion 51c is formed in the shape of a regular hexagon along the outer shape of the outer surface 51b. The positioning portion 51c also has a height H that is lower than the thickness T of the adhesive member 3.

The positioning portion 51c does not have to be a continuous shape like the regular hexagon described above; it may be formed intermittently as long as the positioning function is ensured. For example, the positioning portion 51c may be provided only near each corner.

(Adhesive material)
The adhesive member 3 is a member that detachably attaches the panel unit 2, including the bottom wall 51, to the board surface 100a. The adhesive member 3 has an adhesive force corresponding to the material of the board surface 100a. The size of the adhesive member 3 is determined according to the adhesive force of the adhesive member 3. The greater the adhesive force of the adhesive member 3, the smaller the size of the adhesive member 3 becomes.

The adhesive member 3 is positioned at the location determined by the positioning section 51c. As shown in Figure 2, when the adhesive member 3 is rhombic in shape, multiple adhesive members 3 are provided and positioned to abut against the inner corners of the positioning section 51c.

The shape of the adhesive member 3 is not limited to a rhombus, as long as it can be positioned in contact with the inside of the positioning portion 51c. For example, the adhesive member 3 may be formed as adhesive member 3A, as shown in Figure 8. The adhesive member 3A is formed in a strip shape, positioned between two adjacent corners of the positioning portion 51c. This makes it easy to position even an adhesive member 3A with a relatively long shape.

The adhesive member 3 may be an adhesive sheet. As shown in Figure 7, the adhesive sheet adhesive member 3 has a first adhesive surface 31 on the outer surface 51b side and a second adhesive surface 32 on the board surface 100a side. The first adhesive surface 31 adheres to the outer surface 51b, and the second adhesive surface 32 adheres to the board surface 100a. The adhesive strength of the first adhesive surface 31 is higher than that of the second adhesive surface 32. In particular, it is preferable that the adhesive strength of the first adhesive surface 31 is higher than that of the material of the outer surface 51b. This reduces the likelihood of the adhesive member 3 peeling off the outer surface 51b while remaining attached to the board surface 100a when the structure 10 is removed from the board surface 100a.

The adhesive sheet may be light-transmitting. If the panel unit 2 is light-transmitting, the panel surface 100a becomes more visible from the side of the closing member 4. By making the adhesive sheet light-transmitting, the adhesive sheet can be made less conspicuous. However, even if the adhesive sheet is light-transmitting, the adhesive sheet may still be noticeable due to differences in material between the panel unit 2 and the adhesive sheet. In contrast, as shown in Figure 2, by arranging multiple attachment members 3 at positions far apart from each other, the attachment members 3 of the adhesive sheet can be made even less conspicuous.

The adhesive member 3 may be a magnetic sheet. If the adhesive member 3 is a magnetic sheet, the plate surface 100a is formed of a material that is attracted by the magnetic force of the magnetic sheet. The shape of the magnetic sheet is not limited to the shapes of the adhesive members 3 and 3A described above.

For example, the adhesive member 3, which is a magnetic sheet, may be formed as an adhesive member 3B, as shown in Figure 9. The adhesive member 3B has a regular hexagonal shape that conforms to the inner shape of the positioning portion 51c. The adhesive member 3B is positioned so that its outer circumference abuts against the inside of the positioning portion 51c, covering the entire area inside the positioning portion 51c on the outer surface 51b.

Furthermore, the magnetic sheet adhesive member 3 may be formed as adhesive members 3C and 3D, as shown in Figures 10 and 11. The adhesive members 3C and 3D are formed in a strip shape of a constant width along the inside of each side of the positioning portion 51c. A small gap is provided between two adjacent adhesive members 3C. Similarly, a small gap is provided between two adjacent adhesive members 3D. Adhesive member 3D has a wider width than adhesive member 3C. Adhesive member 3C has a stronger magnetic force than adhesive member 3D.

The magnetic sheet is attached to the outer surface 51b using double-sided tape or the like. The surface of the magnetic sheet attached to the outer surface 51b is a painted surface colored white or the like. Therefore, if the panel unit 2 is light-transmitting, the painted surface of the magnetic sheet is visible from the surface, thus concealing dirt and scratches on the panel surface 100a. Furthermore, using the magnetic sheet makes it easy to attach and detach the structure 10 from the panel surface 100a.

The partition member 5 has the above-described adhesive structure on its outer surface 51b. In this adhesive structure, the adhesive member 3 is positioned to abut against the inside of the positioning portion 51c. This allows for proper positioning of adhesive members 3, which are formed to various sizes according to the adhesive force. Therefore, variations in adhesive strength due to the adhesive member 3 can be reduced. Consequently, attachment and detachment of the structure 10 to the plate surface 100a can be easily achieved.

In this embodiment, an example in which the attachment member 3 is composed of an adhesive sheet and a magnetic sheet has been described, but the attachment member 3 is not limited to an adhesive sheet and a magnetic sheet. For example, a hook-and-loop fastener may be used as the attachment structure for attaching the structure 10 to the board surface 100a. When using a hook-and-loop fastener, one sheet of the hook-and-loop fastener is provided as the attachment member 3 on the outer surface 51b of the partition member 5, and the other sheet of the hook-and-loop fastener is provided on the board surface 100a.

[Embodiment 2]
Embodiment 2 of this disclosure will be described below. For the sake of clarity, components having the same function as those described in Embodiment 1 will be denoted by the same reference numerals, and their descriptions will not be repeated.

Figure 12 is a cross-sectional view taken along the line B-B in Figure 1. Figure 13 is a cross-sectional view showing an enlarged portion of Figure 12. Figure 14 is a cross-sectional view showing another enlarged portion of Figure 12. Figure 15 is a front view showing the partition member 5.

(Interlocking structure)
In this embodiment, the fitting structure of the closing member 4 and the partitioning member 5 will be described in detail.

As shown in Figures 12 and 13, the closing wall 41 of the closing member 4 has a groove 41a on its inner surface. The groove 41a is formed to fit with the upper end of the partition wall 53.

As shown in Figures 12 and 14, the closing member 4 is fitted to the partition member 5 at the side wall 42 that constitutes its outer periphery. The side wall 52 of the partition member 5 has a recess 52a at approximately the center of the width direction of the end face where it is joined to the closing member 4. As shown in Figure 15, the recess 52a extends across the entire length of the side wall 52 that constitutes the outer periphery of the partition member 5. Furthermore, the side wall 52 has an extension wall 52b that rises up near the recess 52a. The surface of the extension wall 52b on the recess 52a side is formed to be continuous with the side surface that forms the recess 52a at its lower end.

The inner surface of the side wall 42 faces the outer surface of the extension wall 52b, while the inner surface of the extension wall 52b faces the outer surface of the extension wall 52b. Furthermore, the side wall 42 has a projection 42a on the end face that connects to the partition member 5, which fits into the recess 52a. The projection 42a is provided on the inner surface side of the side wall 42 at the aforementioned end face.

The closing member 4 and the partition member 5 are joined not only by the side wall 42 fitting into the side wall 52, but also by the partition wall 53 fitting into the groove 41a, thereby increasing the strength of the joint. Therefore, a highly strong structure 10 with multiple internal spaces can be provided.

Furthermore, the strength of the bond is further increased by joining the closing member 4 and the partitioning member 5 at the aforementioned fitting portion using an adhesive or the like. This joining creates a sealed space between the closing member 4 and the bottom wall 51, side walls 52, and partition wall 53 of the partitioning member 5. The partition wall 53 demarcates this space.

In this embodiment, an example was described in which the partitioning member 5 has a partition wall 53. Alternatively, instead of the partitioning member 5 having a partition wall 53, the closing member 4 may function as a partitioning member by having a partition wall similar to that of the partition wall 53. In such a closing member 4, the partitioning member 5 functions as a closing member by having a groove that fits into the partition wall of the closing member 4. Furthermore, in such a structure, the side wall 42 has a recess, and the side wall 52 has a protrusion that fits into the recess of the side wall 42. This structure also achieves the same effects as the structure of this embodiment.

(Clearance difference)
The clearance C1 between the bulkhead 53 and the groove 41a is expressed by the following equation. In the following equation, W1 represents the width of the opening of the groove 41, and W2 represents the width of the upper end of the bulkhead 53.

C1 = W1 - W2
The clearance C2 between the recess 52a and the protrusion 42a is expressed by the following equation. In the following equation, D1 represents the distance between the inner wall surface on the extension wall 52b side of the recess 52a and the protrusion 42a, and D2 represents the distance between the inner wall surface on the opposite side of the extension wall 52b side of the recess 52a and the protrusion 42a.

C2 = D1 + D2
The widths W1 and W2 and the distances D1 and D2 are determined such that the clearance C1 is smaller than the clearance C2. For example, if W1 = 1 [mm], W2 = 0.9 [mm], D1 = 0.3 [mm], and D2 = 0.3 [mm], then C1 = 0.1 [mm] and C2 = 0.6 [mm], so the clearance C1 is smaller than the clearance C2.

Please note that the above values are merely examples; the widths W1 and W2, and the distances D1 and D2 should be set appropriately according to the difference between the clearances C1 and C2.

As described above, by setting clearances C1 and C2, the fitting between the partition wall 53 and the groove 41a can be accurately performed, while the fitting at the side walls 42 and 52 can be made looser. This reduces problems such as the closing member 4 and the partition member 5 not fitting properly or being too loose and rattling due to molding errors in these members.

[Embodiment 3]
Embodiment 3 of this disclosure will be described below. For the sake of convenience, components having the same function as those described in Embodiments 1 and 2 will be denoted by the same reference numerals, and their descriptions will not be repeated.

Figure 16 is a cross-sectional view taken along the line C-C in Figure 15. Figure 17 is an enlarged cross-sectional view of a portion of Figure 16. Figure 18 is a side view of another structure 10A. Figure 19 is an enlarged cross-sectional view of a portion of the cross-section taken along the line D-D in Figure 18. Figure 20 is a longitudinal cross-sectional view of the structure shown in the cross-sectional view of Figure 18.

(First adhesive storage structure)
As described in Embodiment 2, as shown in Figures 15 to 17, the side wall 52 of the partition member 5 has a recess 52a. The recess 52a functions as a reservoir for storing a low-viscosity adhesive 6. The blocking member 4 and the partition member 5 are joined together by the adhesive 6 stored in the recess 52a.

In the manufacturing process of the structure 10, when joining the closing member 4 and the partition member 5, adhesive 6 is first poured into the recess 52a and stored there. In this state, when the closing member 4 is placed over the partition member 5 and the protrusion 42a of the side wall 42 is fitted into the recess 52a, the adhesive 6 stored in the recess 52a overflows and spreads between the joint surface of the closing member 4 and the partition member 5 shown in Figure 14, i.e., between the side wall 42 and the side wall 52 (extension wall 52b).

As a result, unlike adhesives applied to joint surfaces in conventional structures, the adhesive 6, which spreads as described above, is less prone to air bubbles and uneven application. In particular, when the closing member 4 is light-transmitting, the joint surface between the closing member 4 and the partition member 5 becomes more visible from the outside. Therefore, the reduction in aesthetic appeal due to the adhesive 6 can be minimized.

As shown in Figure 15, the recess 52a is provided across the entire side wall 52. Similarly, the protrusion 42a is also provided across the entire side wall 42. This allows the adhesive 6 to spread evenly across the entire side wall 52. This increases the bonding strength of the fitting portion between the recess 52a and the protrusion 42a.

Furthermore, the recess 52a may be provided not across the entire side wall 52, but only on a portion of the side wall 52. Conversely, the protrusion 42a is also provided in a position that fits into the recess 52a.

As also described in Embodiment 2, in this embodiment, the side wall 42 may have a recess, and the side wall 52 may have a protrusion that fits into the recess of the side wall 42. In such a structure, the recess of the side wall 42 functions as a reservoir for storing the adhesive 6.

(Second adhesive storage structure)
As shown in Figures 18 to 20, the structure 10A comprises a panel unit 2A and an adhesive member 3. The panel unit 2A has a closing member 4A and a partitioning member 5A. The closing member 4A is configured the same as the closing member 4, except that it does not have the protrusion 42a that the closing member 4 has. The partitioning member 5A is configured the same as the partitioning member 5, except that it has a recess 52Ab instead of the recess 52a that the partitioning member 5 has.

The partition member 5A has a polygonal (regular hexagonal) outer shape, similar to the side wall 52, and includes a side wall 52A that forms the outer periphery of the partition member 5A. The closing member 4A also has a polygonal (regular hexagonal) outer shape, similar to the side wall 42, and includes a side wall 42A (second side wall) that faces the side wall 52A on its outside. As shown in Figure 20, the side wall 52A (first side wall) has a contact surface 52Aa against which the end of the side wall 42A abuts. Furthermore, recesses 52Ab are provided at each corner of the side wall 52A.

The recess 52Ab extends from the surface formed by extending the contact surface 52Aa to the upper end of the side wall 52A. The recess 52Ab functions as a reservoir for storing the high-viscosity adhesive 6. The closing member 4A and the partition member 5A are joined by the adhesive 7 stored in the recess 52Ab.

In the manufacturing process of the structure 10A, when joining the closing member 4A and the partition member 5A, adhesive 7 is first applied and stored in the recess 52Ab. In this state, the side wall 42A is placed over the side wall 52A so that its end contacts the contact surface 52Aa. This causes the adhesive 7 to spread by gravity within the space formed by the recess 52Ab between the side wall 42A and the side wall 52A. As a result, the side walls 42A and 52A are joined at the corners, reducing the amount of adhesive applied. Therefore, even if the overlapping portion of the side walls 42A and 52A becomes more visible due to the light-transmitting properties of the closing member 4A, the reduction in aesthetic appeal due to the adhesive 7 can be minimized. Furthermore, the amount of adhesive 7 used can be reduced, and the efficiency of the bonding process can be improved.

[Embodiment 4]
Embodiment 4 of this disclosure will be described below. For the sake of convenience, components having the same function as those described in Embodiments 1 to 3 will be denoted by the same reference numerals, and their descriptions will not be repeated.

Figure 21 shows an example in which multiple of the above-described structures according to this embodiment constitute a glass plate privacy structure.

As shown in Figure 21, the privacy screen structure 1 is attached to the surface 100Aa of a translucent panel 100A, such as a transparent glass wall in a conference room, for the purpose of protecting privacy and decoration, in order to block the line of sight.

The blindfold structure 1 comprises a plurality of light-transmitting structures 10, 10A. Each of the plurality of structures 10, 10A includes an obscuring member 4, 4A that provides image shielding, and is individually attachable and detachable from the plate surface 100Aa by a light-transmitting adhesive member 3. In this disclosure, image shielding means that the inside or outside becomes difficult to see through the obscuring members 4, 4A. In other words, in this disclosure, image shielding means that the image of an object cannot be clearly seen through the obscuring members 4, 4A, and the image of the object is seen in a cloudy (blurred), distorted, or partially obscured state.

Specifically, the blocking members 4 and 4A may be semi-transparent. This obscures the image of an object so that it appears blurred (cloudy) when viewed through the blocking members 4 and 4A. By adjusting the light transmittance of the semi-transparent blocking members 4 and 4A, the desired level of image shielding can be provided to the blocking members 4 and 4A. Furthermore, a portion of the blocking members 4 and 4A may be semi-transparent. In other words, the blocking members 4 and 4A may include both transparent and semi-transparent portions. This allows the image of an object to be clearly visible through the transparent portion of the blocking members 4 and 4A, while the image of an object cannot be clearly visible through the semi-transparent portion, resulting in a blurred (cloudy) image.

Alternatively, a portion of the blocking members 4 and 4A may be opaque. That is, the blocking members 4 and 4A may include both transparent and opaque portions. This allows the image of an object to be clearly visible through the transparent portion of the blocking members 4 and 4A, while the image of the object is not visible through the opaque portion, effectively obscuring the view so that the image is visible only partially.

Furthermore, the blocking members 4 and 4A may have a three-dimensional shape that protrudes toward the opposite side from the plate surface 100Aa. This causes light to be refracted by the blocking members 4 and 4A, obscuring the image of an object so that it is viewed through the blocking members 4 and 4A in a distorted state. In this case, even if the entire blocking members 4 and 4A are transparent, they can still be given an image-shielding property. Moreover, the image-shielding property can be improved by making all or part of the three-dimensional blocking members 4 and 4A semi-transparent.

By attaching the privacy structure 1 to a portion of the surface 100Aa of the transparent light-transmitting plate 100A, it becomes difficult to see inside or outside the conference room through the blocking members 4 and 4A. For example, in the portion of the surface 100Aa where the privacy structure 1 is not attached, the image of an object can be clearly seen from the outside through the light-transmitting plate 100A. On the other hand, in the portion of the surface 100Aa where the privacy structure 1 is attached, the image of an object cannot be clearly seen from the outside through the image-shielding blocking members 4 and 4A. As a result, while the presence of an object is visible, its clear image is obscured.

Thus, the privacy screen structure 1 provides privacy by combining multiple panel units 2 and attaching them to the board surface 100Aa. Therefore, unlike conventional film-based privacy screens, it does not wrinkle or peel due to aging or deterioration.

Furthermore, with the privacy structure 1, the panel units 2 can be individually attached and detached using the adhesive members 3. This allows for easy changes to the attachment position of the panel units 2. Therefore, it offers greater flexibility in redecorating and facilitates changes to the spatial design.

Furthermore, the translucent panel 100A to which the privacy screen structure 1 is attached is not limited to a glass wall; for example, it may be a transparent screen or partition, a glass window, a glass door, etc. Also, the translucent panel 100A only needs to be light-transmitting and allow the interior to be seen through; it can be made of various materials such as glass, polycarbonate, or acrylic.
