DETAILED DESCRIPTION OF THE INVENTION

[0010] A preferred embodiment of the present disclosure will be described.

[0011] The locking member of the present disclosure can be movable between a restricting position that restricts movement of the wall mounting member from the locking recess to the insertion recess, and an allowing position that allows movement of the wall mounting member between the locking recess and the insertion recess. In this case, the sign body and the wall mounting member can be repeatedly attached and detached, and can be easily replaced with a different wall mounting member.

[0012] When the locking member of the present disclosure is in the restricted position, it may protrude into the recess, preventing the wall mounting member from moving within the recess, thereby reliably restricting the wall mounting member from moving from the locking recess to the insertion recess.

[0013] The locking member of the present disclosure may be magnetic, which makes it possible to use a magnet to displace the locking member from the restricting position to the allowing position, which is convenient to use.

[0014] <Embodiment 1> A first embodiment of a signboard 10 according to the present disclosure will be described with reference to Figures 1 to 9. In the following description, the front-to-back, left-to-right, and up-to-down directions of the signboard 10 are represented using the X-axis, Y-axis, and Z-axis shown in each figure. The positive directions of the X-axis, Y-axis, and Z-axis are forward, left, and upward, respectively.

[0015] [Signboard configuration] As shown in FIGS. 1 and 2, the signboard 10 of the first embodiment includes a signboard main body 11, a locking member 12, and a wall mounting member 13.

[0016] [Signboard body configuration] The signboard main body 11 is made of, for example, synthetic resin. The signboard main body 11 has a rectangular flat plate shape with four rounded corners. The rear plate surface of the signboard main body 11 is the facing surface Os that faces and contacts the wall surface W. The front plate surface of the signboard main body 11 is the exposed surface Ex on which letters, figures, etc. are attached. A recess 11A is formed on the facing surface Os of the signboard main body 11. The recess 11A is formed so as to be recessed from the facing surface Os toward the exposed surface Ex.

[0017] As shown in FIG. 3, the recess 11A has an insertion recess 11B and a locking recess 11C. When the opposing surface Os is viewed from the rear, the insertion recess 11B has a rectangular shape. The locking recess 11C is arranged in communication with the insertion recess 11B. The insertion recess 11B and the rear surface 11E (bottom surface) of the locking recess 11C are flush with each other. The locking recess 11C has a vertical dimension that gradually decreases as it moves leftward from the insertion recess 11B, and the vertical dimension at the left end farthest from the insertion recess 11B is constant. The locking recess 11C is provided with a pair of locking protrusions 11D. Each locking protrusion 11D is provided along the upper and lower edges of the locking recess 11C and protrudes from each edge toward the vertical center of the locking recess 11C.

[0018] The insertion recess 11B has inclined surfaces 11H formed between the rear surface 11E and the upper surface 11F, and between the rear surface 11E and the lower surface 11G. Each inclined surface 11H slopes from the upper surface 11F and the lower surface 11G toward the center in the vertical direction and toward the rear surface 11E. A rear-surface inclined surface 11J is formed at each of the upper and lower ends of the locking recess 11C so as to be continuous with the respective inclined surfaces 11H. An opposing-surface inclined surface 11K is formed on the front side of the locking protrusion 11D. The opposing-surface inclined surface 11K slopes from the opposing surface Os toward the rear surface 11E so as to widen outward in the vertical direction. The front edge of the opposing-surface inclined surface 11K is continuous with the rear edge of the rear-surface inclined surface 11J. The opposing-surface inclined surface 11K and the rear-surface inclined surface 11J are continuous in a V-shape.

[0019] As shown in FIG. 2, the signboard main body 11 is formed with a storage section 11L. The storage section 11L has an opening 11M and a communication hole 11N. The opening 11M is recessed from the opposing surface Os toward the exposed surface Ex. The opening 11M is open rearward. The communication hole 11N extends in the vertical direction and is formed to communicate with the opening 11M and the insertion recess 11B. The communication hole 11N is adjacent to the locking recess 11C from the right and communicates with the left end of the insertion recess 11B. The cross-sectional shape of the communication hole 11N perpendicular to the vertical direction is circular (see FIG. 3).

[0020] [Configuration of locking members] The locking member 12 is made of, for example, synthetic resin. The locking member 12 has a shaft portion 12A, a flange portion 12B, and a magnetic member 12D. The shaft portion 12A is cylindrical and extends in the vertical direction. The flange portion 12B is provided at the upper end of the shaft portion 12A and is formed with a flange-like diameter that is larger than that of the shaft portion 12A. A downwardly recessed hole portion 12C is formed at the upper end of the shaft portion 12A above the flange portion 12B.

[0021] The magnetic member 12D is made of, for example, a magnetic metal such as iron, or a magnetic material such as a magnet. The magnetic member 12D is embedded in the hole 12C. In other words, the locking member 12 is magnetic. The shaft 12A of the locking member 12 is inserted into the communicating hole 11N. The flange 12B of the locking member 12 is disposed in the open portion 11M. In this state, the locking member 12 is accommodated in the accommodation portion 11L. The outer diameter of the flange 12B is larger than the outer diameter of the communicating hole 11N. Therefore, the flange 12B of the locking member 12 contacts the lower surface of the open portion 11M, preventing it from falling into the insertion recess 11B. When the flange 12B contacts the lower surface of the open portion 11M, the lower end of the shaft 12A protrudes into the insertion recess 11B. For example, the storage section 11L is constructed of a separate member so that the opposing surface Os side of the communicating hole section 11N can be opened, and after the locking member 12 is stored in the storage section 11L with the opposing surface Os side of the communicating hole section 11N open, the communicating hole section 11N is closed by the separate member.

[0022] For example, when a magnet M is brought close to the storage section 11L from above, the magnetically attracted member 12D of the locking member 12 is attracted to the magnet M. This causes the locking member 12 to move upward within the storage section 11L. At this time, the lower end of the shaft 12A leaves the insertion recess 11B and is accommodated within the communication hole 11N of the storage section 11L (see the locking member 12 shown by the dotted line in FIG. 2). When the magnet M is moved away from the storage section 11L, the locking member 12 moves downward within the storage section 11L due to its own weight. Then, the lower end of the shaft 12A re-enters the insertion recess 11B (see the locking member 12 shown by the solid line in FIG. 2).

[0023] [Wall mounting component configuration] The wall mounting member 13 is made of, for example, synthetic resin. As shown in FIG. 4 , the wall mounting member 13 is flat and has a thickness in the front-to-rear direction. The upper and lower edges of the wall mounting member 13 are provided with tapered portions 13A extending from the left end to the right end, such that the thickness in the front-to-rear direction decreases outward in the up-down direction. Specifically, the tapered portions 13A are formed with a front inclined surface 13F and a rear inclined surface 13G that are inclined so that they approach each other in the front-to-rear direction toward the upper end (lower end). The upper edges (lower edges) of the front inclined surface 13F and the rear inclined surface 13G are continuous from the left end to the right end. The wall mounting member 13 is formed with a pair of through holes 13B that penetrate in the plate thickness direction, side by side in the left-to-right direction. The front ends of each through hole 13B are formed with enlarged diameter portions 13C that are enlarged in diameter.

[0024] The wall mounting member 13 has an inclined portion 13D and a parallel portion 13E. The inclined portion 13D is formed so that its vertical dimension gradually decreases from the right end to the left. The parallel portion 13E is connected to the left end of the inclined portion 13D and extends leftward. The parallel portion 13E extends leftward while maintaining the cross-sectional shape perpendicular to the left-right direction at the left end of the inclined portion 13D. In other words, the vertical dimension of the parallel portion 13E is constant in the left-right direction.

[0025] [Example of steps to attach a sign to a wall] First, the worker attaches the wall mounting member 13 to the wall surface W. Specifically, as shown in FIG. 5 , the worker adjusts the orientation of the wall mounting member 13 so that the inclined portion 13D and the parallel portion 13E are aligned in the left-right direction, and brings the rear surface into surface contact with the wall surface W. In the case of embodiment 1, the wall mounting member 13 is adjusted so that the parallel portion 13E is positioned to the left of the inclined portion 13D. Then, the worker inserts screws S into each through hole 13B and tightens the screws S into the wall surface W. In this way, the wall mounting member 13 is fixed to the wall surface W.

[0026] Next, the sign body 11 is attached to the wall mounting member 13 fixed to the wall surface W. Specifically, the worker adjusts the orientation of the sign body 11 so that the locking member 12 protrudes above the recessed portion 11A while aligning the opposing surface Os with the wall surface W. Next, the worker fits the wall mounting member 13 into the recessed portion 11A. Specifically, as shown in FIG. 6, the worker inserts the wall mounting member 13 into the insertion recessed portion 11B. At this time, the parallel portion 13E of the wall mounting member 13 is adjacent to the locking recessed portion 11C from the right side. The opposing surface Os is in surface contact with the wall surface W (not shown).

[0027] Next, as shown in Figure 7, the worker moves the signboard main body 11 in parallel to the right (left in Figure 7) while keeping the opposing surface Os in surface contact with the wall surface W. This causes the wall mounting member 13 to enter the locking recess 11C from the insertion recess 11B. At this time, the lower end of the shaft 12A of the locking member 12 protruding into the insertion recess 11B comes into contact with the upper edge (tip edge) of the tapered portion 13A above the inclined portion 13D of the wall mounting member 13 and is pushed up. As the wall mounting member 13 moves from the insertion recess 11B to the locking recess 11C, each tapered portion 13A locks with each locking protrusion 11D of the locking recess 11C. Specifically, when each tapered portion 13A is engaged with each locking protrusion 11D of the locking recess 11C, the state in which each tapered portion 13A is sandwiched between the wall surface W and each locking protrusion 11D, the front inclined surface 13F faces the rear inclined surface 11J from behind, and the rear inclined surface 13G faces the opposing inclined surface 11K from the front (see Figure 9).

[0028] Furthermore, as shown in FIG. 8, the worker moves the signboard main body 11 parallel to the right (left in FIG. 8) while keeping the opposing surface Os in surface contact with the wall surface W. This causes the entire wall mounting member 13 to enter the locking recess 11C. The left end face of the wall mounting member 13 then abuts against the left end face of the locking recess 11C from the left. At this time, the entire wall mounting member 13 passes leftward below the shaft portion 12A of the locking member 12. The locking member 12 then moves downward through the storage portion 11L due to its own weight, and the lower end of the shaft portion 12A again protrudes into the insertion recess 11B. At this time, the lower end of the shaft portion 12A abuts against the right end face of the inclined portion 13D from the right. At this time, the locking member 12 is in a restricting position that restricts the wall mounting member 13 from moving from the locking recess 11C to the insertion recess 11B.

[0029] When the locking member 12 is in the restricted position, the lower end of the locking member 12 protrudes into the recess 11A. If an attempt is made to move the sign body 11 leftward (toward the right in FIG. 8 ) with the locking member 12 in the restricted position, the right end face of the inclined portion 13D abuts against the lower end of the shaft portion 12A. Therefore, when the locking member 12 is in the restricted position, the sign body 11 cannot be removed from the wall mounting member 13. In this way, the worker mounts the sign body 11 on the wall W. At this time, as shown in FIG. 9 , the front inclined surface 13F faces the rear inclined surface 11J in parallel, and the rear inclined surface 13G faces the front inclined surface 11K.

[0030] [Example of how to remove the sign from the wall] The worker brings a magnet M from above close to the accommodation section 11L of the signboard main body 11 attached to the wall W. Then, the magnetically attached member 12D of the locking member 12 is attracted to the magnet M, and the locking member 12 moves upward in the accommodation section 11L. Then, the lower end of the shaft portion 12A of the locking member 12, which protrudes into the insertion recess 11B, is accommodated in the communication hole portion 11N from the insertion recess 11B (see the locking member 12 indicated by the dotted line in FIG. 8). At this time, the locking member 12 is in an allowable position that allows the wall mounting member 13 to move between the locking recess 11C and the insertion recess 11B. When the locking member 12 is in the allowable position, the wall mounting member 13 is freely movable between the locking recess 11C and the insertion recess 11B. In other words, the locking member 12 is freely movable between the restricted position and the allowable position.

[0031] Then, while keeping the magnet M close to the storage section 11L (i.e., while keeping the locking member 12 in the permitted position), the worker translates the sign body 11 to the left (to the right in FIG. 8) with the opposing surface Os in surface contact with the wall surface W. This moves the wall mounting member 13 from the locking recess 11C to the insertion recess 11B, and the engagement between the tapered portion 13A and the locking protrusion 11D is released (see FIG. 6). In this way, the worker removes the sign body 11 from the wall surface W.

[0032] As described above, the signboard 10 of the first embodiment includes the signboard main body 11, the wall mounting member 13 that is attached to a wall surface W and locks the signboard main body 11, and the locking member 12 that is housed in the signboard main body 11. The signboard main body 11 is formed with a recess 11A into which the wall mounting member 13 fits, and the recess 11A has an insertion recess 11B into which the wall mounting member 13 is inserted and a locking recess 11C into which the wall mounting member 13 locks. The wall mounting member 13 is movable between the insertion recess 11B and the locking recess 11C. The locking member 12 restricts the movement of the wall mounting member 13 from the locking recess 11C to the insertion recess 11B. With this configuration, the wall mounting member 13 is inserted into the recess 11A, allowing the facing surface Os of the signboard main body 11 to contact the wall surface W.

[0033] The locking member 12 is movable between a restricting position that restricts the movement of the wall mounting member 13 from the locking recess 11C to the insertion recess 11B, and an allowing position that allows the wall mounting member 13 to move between the locking recess 11C and the insertion recess 11B. This allows the sign body 11 and the wall mounting member 13 to be repeatedly attached and detached, and makes it easy to replace the wall mounting member 13 with a different one.

[0034] When the locking member 12 is in the restricted position, it protrudes into the insertion recess 11B of the recess 11A. Therefore, the locking member 12 protruding into the insertion recess 11B prevents the wall mounting member 13 from moving within the recess 11A, so that the movement of the wall mounting member 13 from the locking recess 11C to the insertion recess 11B can be reliably restricted.

[0035] The locking member 12 is magnetic, so that the locking member 12 can be displaced from the restricting position to the allowing position using the magnet M, which is convenient to use.

[0036] <Embodiment 2> A second embodiment of a signboard 20 according to the present disclosure will be described with reference to Figures 10 to 17. The signboard 20 of the second embodiment differs from the first embodiment in the shape of the recess 21A in the signboard main body 21 and the shape of the wall mounting member 23. In the following description, the same components as those of the first embodiment are designated by the same reference numerals, and redundant description will be omitted.

[0037] [Signboard configuration] As shown in FIG. 10, the signboard 20 of the second embodiment includes a signboard main body 21, a locking member 12, and a wall mounting member 23.

[0038] [Signboard body configuration] A recess 21A is formed on the facing surface Os of the signboard main body 21. The recess 21A is formed to be recessed from the facing surface Os toward the exposed surface Ex (see FIG. 11).

[0039] When the signboard main body 11 is viewed from the opposing surface Os side, the recess 21A has a generally circular shape, as shown in Fig. 12. The outer peripheral edge of the recess 21A has three pairs of insertion recesses 21B and locking recesses 21C arranged alternately in the circumferential direction. Each locking recess 21C is provided with one locking protrusion 21D. Each locking protrusion 21D is provided along the outer peripheral edge of the recess 21A and protrudes toward the center of the recess 21A.

[0040] The insertion recess 21B and the locking recess 21C are formed with an inclined surface 21H that slopes radially outward from the rear surface 21E toward the opposing surface Os. An opposing surface inclined surface 21K is formed on the front side of the locking protrusion 21D. The opposing surface inclined surface 21K slopes forward while widening radially outward from the inner peripheral edge of the locking protrusion 21D. The front edge of the opposing surface inclined surface 21K is continuous with the rear edge of the inclined surface 21H. The opposing surface inclined surface 21K and the inclined surface 21H are continuous in a V-shape (see FIG. 11).

[0041] When the signboard main body 21 is viewed from the opposing surface Os side, a protrusion 21J protruding in a mountain shape toward the center of the recess 21A is provided between the locking recess 21C and the insertion recess 21B adjacent to the locking recess 21C on one side in the circumferential direction. In the second embodiment, three protrusions 21J are provided.

[0042] As shown in Fig. 11, a storage section 11L is formed in the signboard main body 21. The storage section 11L has an opening 11M and a communication hole 11N. The communication hole 11N extends in the vertical direction and is formed to communicate with the opening 11M and one of the locking recesses 21C (see Fig. 12).

[0043] [Configuration of locking members] With the lower end of flange 12B in contact with the lower surface of open section 11M, the lower end of shaft 12A of locking member 12 protrudes into locking recess 21C. For example, when a magnet M is brought close to storage section 11L from above, magnetic member 12D of locking member 12 is attracted to magnet M, and locking member 12 moves upward within storage section 11L. At this time, the lower end of shaft 12A leaves locking recess 21C and enters communicating hole 11N of storage section 11L (see locking member 12 indicated by dotted lines in FIG. 11).

[0044] When the magnet M is moved away from the storage section 11L, the locking member 12 moves downward within the storage section 11L due to its own weight, and the lower end of the shaft 12A then re-enters the locking recess 21C (see the locking member 12 shown by the solid line in FIG. 11).

[0045] [Wall mounting component configuration] The wall mounting member 23 is made of, for example, synthetic resin. As shown in FIG. 13 , the wall mounting member 23 has a flat plate shape with a thickness in the front-to-rear direction. The wall mounting member 23 has a triangular shape with three arc-shaped vertices. Three tapered portions 23A are provided on the outer peripheral edge of the wall mounting member 23, which protrude outward while decreasing in thickness in the front-to-rear direction. A blind hole 23E is formed in one of the three tapered portions 23A. The blind hole 23E is recessed from the protruding end of the tapered portion 23A toward the base end. Four through holes 23B are formed in a row in the wall mounting member 23, penetrating in the plate thickness direction. An expanded diameter portion 23C is formed at the front end of each through hole 23B.

[0046] [Example of steps to attach a sign to a wall] First, the worker attaches the wall mounting member 23 to the wall surface W. Specifically, as shown in FIG. 14 , the worker adjusts the orientation of the wall mounting member 23 so that the tapered portion 23A in which the blind hole 23E is formed is located at the upper end, and brings the rear surface into surface contact with the wall surface W. Then, the worker inserts screws S into each through hole 23B and tightens the screws S into the wall surface W. In this way, the wall mounting member 23 is fixed to the wall surface W.

[0047] Next, the sign body 21 is attached to the wall mounting member 23 fixed to the wall surface W. Specifically, the worker adjusts the orientation of the sign body 21 so that the locking member 12 is adjacent to the right of the tapered portion 23A in which the blind hole 23E is formed, while aligning the opposing surface Os with the wall surface W. Next, the worker inserts the wall mounting member 23 into the recess 21A, as shown in FIG. 15. At this time, each tapered portion 23A of the wall mounting member 23 is inserted into each insertion recess 21B. The opposing surface Os then comes into surface contact with the wall surface W (not shown).

[0048] Next, the worker rotates the sign body 21 in a direction that moves the locking member 12 leftward, while keeping the opposing surface Os in surface contact with the wall surface W. As a result, each tapered portion 23A of the wall mounting member 23 enters the locking recess 21C from the insertion recess 21B, as shown in FIG. 16. At this time, the lower end of the shaft portion 12A of the locking member 12 that protrudes into the locking recess 21C comes into contact with the right edge of the tapered portion 23A, in which the blind hole 23E is formed, and is pushed up. Each tapered portion 23A of the wall mounting member 23 moves from the insertion recess 21B to the locking recess 21C, thereby locking with each locking protrusion 21D.

[0049] Furthermore, while keeping the opposing surface Os in surface contact with the wall surface W, the worker rotates the sign body 21 in a direction that moves the locking member 12 leftward. As a result, each tapered portion 23A is engaged with each of the locking protrusions 21D along the entire circumferential direction, as shown in FIG. 17 . When the shaft portion 12A of the locking member 12 reaches directly above the blind hole 23E, the locking member 12 moves downward through the storage portion 11L due to its own weight, and the lower end of the shaft portion 12A again protrudes into the locking recess 21C and is inserted into the blind hole 23E. Thus, the locking member 12 is positioned in a restricted position that restricts the tapered portion 23A of the wall mounting member 23 from moving from the locking recess 21C into the insertion recess 21B. Furthermore, one end of each tapered portion 23A in the circumferential direction abuts against each of the protrusions 21J. This prevents the sign body 21 from rotating unrestrictedly. In this way, the worker attaches the signboard main body 21 to the wall surface W.

[0050] [Example of how to remove the sign from the wall] The worker brings the magnet M from above close to the accommodation section 11L of the signboard main body 21 attached to the wall surface W. The magnetically attracted member 12D of the locking member 12 is then attracted to the magnet M, causing the locking member 12 to move upward in the accommodation section 11L. The lower end of the shaft portion 12A of the locking member 12, which has entered the blind hole 23E, is then released from the blind hole 23E and accommodated in the communicating hole portion 11N. At this time, the locking member 12 is positioned in an allowable position that allows each tapered portion 23A of the wall mounting member 23 to move from the locking recess 21C to the insertion recess 21B. Then, while keeping the magnet M close to the accommodation section 11L (i.e., while maintaining the locking member 12 positioned in the allowable position), the worker rotates the signboard main body 21 in a direction that moves each tapered portion 23A away from the protrusion 21J, with the opposing surface Os in surface contact with the wall surface W. Then, each tapered portion 23A of the wall mounting member 23 moves from the locking recess 21C to the insertion recess 21B, and the locking between the tapered portion 23A and the locking protrusion 21D is released (see FIG. 15). In this way, the worker removes the signboard main body 21 from the wall surface W.

[0051] The present disclosure is not limited to the embodiments described above and illustrated in the drawings, and the following embodiments, for example, are also included within the technical scope of the present disclosure.

[0052] (1) Unlike the first embodiment, the entire locking member may be made of a magnetic material such as a metal. (2) Unlike the first embodiment, the locking recess may be formed in a T-groove or dovetail groove shape. (3) The materials for the sign body and the wall mounting member are not limited to those in the first embodiment, but may be wood, metal, glass, or the like. (4) The external shape of the signboard body is not limited to those in the first and second embodiments. (5) The cross-sectional shape of the communication hole portion perpendicular to the vertical direction is not limited to that in the first and second embodiments. (6) Unlike the second embodiment, the number of pairs of insertion recesses and locking recesses may be two, or may be four or more. (7) The number of through holes in the wall mounting member is not limited to that in the first and second embodiments. (8) Unlike the second embodiment, the protrusions may not be provided. (9) Unlike the first and second embodiments, the locking member may be disposed to the left or right of or below the recess. For example, a compression coil spring is disposed between the flange of the locking member and the surface of the open portion facing away from the recess. The compression coil spring biases the locking member toward the recess. The elastic repulsive force of the compression coil spring is set to be smaller than the magnetic force of the magnet that attracts the magnetic member. As a result, when the magnet is brought closer to the storage portion, the compression coil spring is compressed and the magnetic member is attracted to the magnet. When the magnet is moved away from the storage portion, the elastic repulsive force of the compression coil spring moves the locking member toward the recess. [Explanation of symbols]
