Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a stand type guide display,
The present invention relates to a display device capable of displaying a wall-mounted guide display, a hanging guide display, a tabletop guide display, and other appropriate modes.

[0002]

2. Description of the Related Art Conventionally, various types of display devices have been provided. However, in order to expose only the display surface and mount the display device, a fixing engaging portion is displayed so that the fixing structure is not shown. The one formed on the back side of the surface is used.

However, since the display surface (surface) of each of the conventional display devices of this type is flat, it is not possible to exert an appealing effect on the display surface form itself apart from the matters described.

[0004]

SUMMARY OF THE INVENTION The present invention adopts a configuration different from such a conventional display device,
Provide a display device that has a better design and appealing effect on the display appearance, and that the fixed structure on the back side of the display device does not appear in the appearance, and that the display plate can be easily attached and detached. It is something to do.

[0005]

In order to achieve the above object, the present invention is a display device having a structure in which a display plate is detachably fixed to a mounting plate, and the fixing portion is provided on the back side of the display plate. It is characterized in that it is formed so as to be located at the position, and the surface of the display plate is formed as a bulging surface in which the intermediate surface slightly bulges forward with respect to the opposing two side portions to form a display device.

Further, the display device of the present invention has the above-mentioned structure and the back surface of the display plate is set to be flat so that the thickness of the display plate itself becomes thicker in the middle portion than in the vicinity of the opposite two side portions. It is also characterized in that it is formed as described above.

In any of the above constructions, the edge portions of the opposite two sides are provided so that the fastening portions are appropriately spaced between the rear surface of the display plate and the front surface of the mounting plate inside (inside) the back side. It is possible to form an overhanging edge portion that maintains a gap between it and the front side of the mounting plate, and the two opposite sides are one opposite side, and other The edge portion of the opposite side can be formed so as to be a protruding edge portion that maintains a gap between the edge portion and the front side of the mounting plate by the fastening portion formed inside (inside) the back side. .

Further, the display plate can be formed so that the back surface is flat, and the thickness of the display plate itself can be formed such that the intermediate portion is thicker than the vicinity of the two opposite sides, and more preferably. It is possible to set one opposing side which is the above-mentioned overhanging edge portion to be longer than the opposing side orthogonal to this.

A plurality of the above-mentioned display plates may be arranged in parallel on the mounting plate, and the entire surface of the display plates arranged in parallel may be formed in a slightly wavy shape to form a display device. The juxtaposed state can be substantially close to each other by the above configuration.
However, it is of course possible to install them in parallel with a proper distance between them. When they are arranged in close proximity to each other, they can be arranged in close contact with each other, but a very small gap such as about 0.5 mm is formed between the overhanging edges of the display boards arranged in parallel. It is preferable that the very small gap formed between the projecting edge portions of the juxtaposed display plates be provided by sandwiching a jig having a thin piece insertion portion between the adjacent display plates. In the case where the display plate can be attached and detached in the front and back direction of the display surface, the jig having the thin piece insertion portion can serve as the display plate detaching jig.

The opposing sides are two opposing sides,
Therefore, the upper and lower surfaces and the left and right surfaces can be formed with the intermediate portion as the bulging surface. Further, when the opposing sides are one opposing side, the end faces of the other opposing sides may be vertical faces, and the end faces of the opposing sides may be machined into inclined faces inclined toward the front side for designing.

In any of the above, the fastening portion can be formed by at least one of the magnet portion of the mounting plate and the display plate and the other magnetically attached surface, and the fastening portion protruding to the back side of the display plate. It is also possible to form the engaging portion and the engaging portion that protrudes to the front side of the mounting plate as an engaging configuration, and it is possible to adopt other appropriate configurations. The display plate can be configured so that it can be attached to and detached from the mounting plate while sliding in the surface direction, but it is most preferable that the display plate can be attached to and detached from the mounting plate in the front-back direction of the display surface. .

[0012]

By bulging the intermediate portion with respect to the opposite two side portions, the display surface can be given three-dimensionality, and the recognition angle of the display surface can be widened even slightly. By making the middle part of the display plate thicker, the end of the display plate can be better accommodated and decoration by edge processing can be appropriately performed.

Since the two opposite side portions of the display plate are the projecting edge portions, it becomes more difficult to see the fastening portion on the back surface side when viewed from the outside, and only the display plate can be floated from the mounting plate. It can improve the design. In addition, attachment / detachment, particularly detachability, can be enhanced. The appearance of the display plate can be made more preferable by setting one opposing side that is the overhanging edge portion to be longer than the opposing side orthogonal to this.

By arranging a plurality of the above-mentioned display plates side by side, the surface of the whole display plate becomes slightly wavy, and the three-dimensional feeling and appeal of the display plate surface can be enhanced. If there is a very small gap between the overhanging edge portions of each display plate, the ease of detaching each display plate is further enhanced. The thin jig inserted into this slight gap can be used for attaching and detaching the display plate.

It is most preferable that the display plate is fastened by attaching and detaching in the front and back direction of the display surface by magnetic attachment means, pressure engaging means, etc. because it can be individually attached and detached, but it is substantially parallel to the display surface. It is also possible to adopt a fastening structure that slides in the direction, a fastening structure such as a tenson type or a spring pressure type that locks while fitting to the side of the display surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings of an embodiment. In the display device of the present invention, the display plate 1 is detachably fixed to the mounting plate 2, and one embodiment thereof will be described first with reference to FIGS.

The display board 1 may be an injection-molded body of synthetic resin or other arbitrary material, but is most preferably an aluminum extruded material cut into a suitable length. A front surface 1a as a display surface capable of arbitrary display is a bulging surface 1b in which an intermediate surface portion slightly bulges forward with respect to the upper and lower sides 1c, 1c which are one opposing two side portions, and its back surface 1d is a bulging surface 1b. Although the surfaces may be substantially parallel to each other, they are preferably formed as flat surfaces so that the middle portion of the display plate has a large thickness, and the left and right end surfaces are vertical end surfaces.

An overhanging edge portion 1e is formed around the display plate 1 so that the back surface of an appropriate width is left as it is, and a fastening portion 3 projecting at an appropriate height is formed in the back surface (inward) to form the fastening portion. 3, a base plate 3a having an appropriate thickness is adhered to the central portion of the back surface 1d, a magnetic sheet 3b is adhered to the top surface, and a metal protective frame 3c is provided on the four sides.
Has been formed.

The mounting plate 2 is formed as a magnetic metal surface which can be magnetically attached when the fixing portion of the display plate 1 is of a magnet construction as described above. This mounting plate 2 is a door surface,
The wall itself may be used. Further, a plate-shaped mounting plate having a specific shape or a plate-shaped mounting plate having a frame can be used as the substrate of the display device. Further, the display plate 1 and the mounting plate 2 may have a one-to-one correspondence form, or a plurality of display plates 1 may be arranged side by side on one mounting plate 2. When a plurality of display plates 1 are arranged side by side, the display plates 1 can be arranged continuously in close contact with each other or in a substantially close contact state, or can be fixed in an appropriately separated state. . In these cases,
As described above, the edge-shaped frame may be formed along the peripheral edge or the left and right edges of the entire display plate 1, but the presence or absence of the frame is arbitrary.

According to the above construction, when the display plate 1 is fixed to the mounting plate 2, a gap 4 having an appropriate depth width is formed on the back side of the upper and lower parts so that the upper and lower parts cover the fixing part 3. The overhanging edge portions 1e, 1e are formed, and the left and right end surfaces are also provided with the gap 4 having the appropriate depth width, and the left and right portions overhang the fastening portion 3 in the same manner as described above. , 1f, the display plate 1 only appears in a state of being slightly floated from the mounting plate 2.

As shown in FIG. 3, the bulging aspect of the bulging surface 1b is such that the surface 1a is an arcuate surface which is curved in the entire vertical direction, and its curvature is small as shown in (A) or large as shown in (B). And the upper and lower sides 1c, 1 as shown in (C)
The vicinity of c may be a curved surface, and the intermediate portion L may be a flat surface, or another bulge form.

FIG. 4 shows an example of a display device in which a plurality of display plates 1 of different sizes are continuously arranged side by side.
Place a plurality of small display boards 1 (three in the figure) side by side,
Adjacent to it, a plurality of medium-sized display boards 1 (2 in the figure)
It is also possible that the display panels 1 are arranged side by side vertically, and further closely adjacent to each other, a suitable number (one in the figure) of large-sized display boards 1 are arranged side by side, and the top and bottom of the display boards 1 arranged side by side are closely attached. In order to easily attach and detach the individual display boards 1 independently, a small gap 5 into which a jig 6 as described later can be inserted, for example, 0.5 is provided.
It is preferable to place them side by side with a gap of about mm. Due to the unevenness of the display surface, the gap of about 0.5 mm is hardly recognized as a gap in appearance, and the display device has an appearance in which the display plates are juxtaposed in a close contact state.

It should be noted that, in order to provide the above-mentioned gap of about 0.5 mm, it can be used as a register, but as shown in FIG. 5, an extremely thin hard plate or a driver shape having a tip of about 0.5 mm. A jig 6 such as the above may be used and applied to one end of one display plate 1 on which the jig 6 is installed, and the adjacent display plates 1 may be juxtaposed so as to contact the display plate 1.

When the display plate 1 is replaced and detached for display replacement, etc., the jig 6 is inserted into a slight gap 5 as shown in FIG. Since one end of 1 is hooked and comes off to the front, it can be detached from the mounting plate 2 as it is.
In this way, a display device in which a plurality of display plates 1 are arranged side by side can be obtained by appropriately combining the display plates 1 or exchanging them as needed, and at the same time, displaying the entire display surface of the display device. Can give an uneven three-dimensional effect.

When the display plates 1 are vertically arranged side by side in both cases of attaching and detaching the display plate 1, as shown in FIG. 6, the display plate 1 is inclined at the time of attachment and detachment and its upper end is slightly upward. In this state, the upper end abuts the lower end of the adjacent upper display panel 1. However, the upper and lower edges of the display board 1 are overhanging edge portions 1e, 1e.
Since there is a gap 4 on the back side, the overhanging edge portion 1e that is displaced upward is adjacent to the overhanging edge portion 1e immediately above.
It is possible to smoothly enter into the space 4 on the back side of the and absorb the upward shift, and therefore, the attachment / detachment of the display panel 1 can be performed individually without affecting the adjacent display panel 1 by displacing the adjacent display panel 1 or the like. Can be performed extremely smoothly and easily.

Further, when a plurality of display plates 1 are arranged in series on the left and right, if the respective bulging surfaces 1b are staggered as shown in FIG. 4, the left and right end surfaces 1e are exposed, but the back surface 1d.
If the plate is flat and the intermediate portion is formed thick, the end face 1e becomes an edge pattern state without a gap even in a perspective state, and the effect of decorating the display surface can be obtained.

FIG. 7 shows a modified example of the above-mentioned display plate 1, which is a display plate 1 having an inclined surface 1g formed by obliquely tapering both left and right end surface portions toward the surface 1a. . According to the display board 1, the inclined surface 1g can be exposed as an edge design together with the three-dimensional state of the bulging surface.

FIG. 8 shows a further modified example of the display plate 1, in which the intermediate surface portion of the display plate is slightly projected forward with respect to the two opposing sides, that is, the two opposing sides, that is, the upper and lower sides. It is formed so as to be a bulging surface, and the upper and lower sides and the left and right sides are thin projecting edge portions.

FIG. 9 shows a modified example of the fastening portion 3 of the display plate 1 described above. Instead of the protective frame 3c, a dovetail-shaped protrusion 1h is provided on the upper rear surface of the display plate 1 in parallel with the upper side 1c. A base plate 3a, which is projected and has an appropriate thickness similar to the above, is formed on the lower back surface of the base plate 3a.
Is adhered, and the magnetic sheet 3b is adhered to the top surface to form a fastening portion.

In the construction in which the display plate 1 can be attached to and detached from the mounting plate 2 in the front and back direction of the display surface, a magnet plate can be fixed to the mounting plate side and magnetically attached to the rear surface side of the display plate, in addition to the above embodiment. A metal plate may be fixed, or the display plate itself may be a magnetic plate that can be magnetically adhered. Further, the configuration as shown in FIGS.
The configuration shown in FIG. 4 or another configuration can be adopted.

The embodiment shown in FIGS. 10 to 13 will be described below. This display device includes a display plate 11, a mounting plate 12 that is fixed to a wall surface, a substrate, or the like by appropriate means or is a part or the whole of the wall surface or the substrate, and a fastening material 13 attached to the back surface of the display plate. The mounting member 14 is fixed to the mounting plate 12.

The display plate 11 is provided with a locking portion 11b having a locking end in the rear surface of the rear surface of the rear surface, which has a protruding edge portion 11a of the display plate near the upper end portion of the rear surface, preferably at the upper end. A mounting portion 11d in which a locking groove portion 11e is formed in the back surface near the lower end portion, preferably at the lower end, where the protruding edge portion 11c of the display plate is left.
Are formed so as to project. In the figure, the mounting portion 11d can be inserted with the fastening material attachment portion 13a, and the locking end 1 of the fastening material 13 can be inserted.
Groove 11e having a substantially C-shaped cross-section that can extend to the portion 3b
And the slit 11f formed in the groove direction on the inner surface of the groove
(The shape is not limited, as long as the edge 14a of the fastening core 14 described later is caught, and the shape is not limited.).

The fastening material 13 is provided at one central portion of the mounting portion 11d on the rear surface of the display plate 11 or at a plurality of appropriate positions in the longitudinal direction at appropriate intervals depending on the length of the display plate 2. Is a member mounted on the display plate 11, and has a curved plate spring shape that slightly bulges in the rear surface direction (direction of the mounting member 14) along the rear surface of the display plate 11, and its lower end has a round tubular core shape. A fastening material mounting portion 13a which can be rotatably inserted into the locking groove portion 11e is formed, an upper end portion serves as a locking end 13b, and a fastening core 13c is detachably mounted in the fastening material mounting portion 13a. It has been inserted. The fastening core 13c has an edge portion having a width slightly larger than the diameter of the fastening material attachment portion 13a at both ends of a core material having a length to be inserted into the fastening material attachment portion 13a. The fastening core 13c is inserted into the fastening material mounting portion 13a by using a slight gap left between the leaf spring portion of the fastening material 13 and the end of the rolled fastening material mounting portion 13a. The edge portions can be attached so as to project to both sides of the fastening material attachment portion 13a.

The mounting member 14 is different from the fastening member 13 in that
It is a member having the same length or an appropriately long and short length, and has an engaging portion 14b projecting from the upper end of the base plate portion 14a so as to engage with the inside of the engaging portion 11b, and the engaging end of the fastening material 13 described above. A support portion 14c for engaging 13b is formed so as to project to an intermediate portion between the locking portion 11b and the mounting portion 11d. The support portion 14c has a lower surface of the protrusion so that the locking end 13b can be easily housed. An engaging concave portion is formed, and a gradual concave curved slope surface 14d is formed downward from the engaging concave portion.

Further, in the above-mentioned structure, the locking portion 1 of the display plate 11 is provided.
1b and the engaging portion of the engaging portion 14b of the mounting member 14, the support portion 14c in which the locking end 13b of the fastening material 13 is locked, and the mounting portion 11d of the display plate 11 in which the fastening material mounting portion 13a is mounted. When the display plate 11 is fixed to the mounting member 14, each of the three parts is mounted by the mounting portion 11d rather than on a straight line connecting the engaging portions of the locking portions 11b to 14b and the supporting portion 14c. The positions are set so as to approach each other in the direction of the member 14, and the locking portion 11b to the engaging portion 14b are set.
The distance between the mounting portion 11d and the bearing portion 14c, which are located on a straight line connecting the engaging portion of the and the bearing portion 13, is greater than the lengths of the fastening material attachment portion 13a of the fastening material 13 and the locking end 13b. It is formed so as to be slightly shorter.

The display plate 11 in the display device having the above structure can be attached and detached as shown in FIG. First, in a state in which the locking portion 11b of the display plate 11 is engaged with the engaging portion 14b of the mounting member 14, the display plate 11 is rotatably mounted at this time in an oblique state in which the lower side is forward. The locking end 13b of the fastening material 13 is in a state of being appropriately opened in the back direction by its own weight, and the locking end 13b is located on the slope surface 14d.
Since it is positioned so as to hit the display board 11 as it is
If the lower side is slightly pushed toward the mounting member 14, the locking end 1
3b shifts up along the slope surface 14d, and while the fastening material 13 rotates in the direction parallel to the back surface of the display plate 11, the locking end 13b locks on the support portion 14c and is further pressed. , The fastening material attaching portion 13 on the straight line connecting the engaging portions of the engaging portions 11b to 14b and the supporting portion 14c.
Before and after a is substantially positioned, the fastening material 13 receives a pressing force and is slightly compressed and deformed from the normal state S to be curved, and elastic force (elastic stress) acts, and the fastening material is attached while receiving the pressing force. When the portion 13a moves to the side of the mounting member 14 rather than on the straight line, the restoring stress of the fastening material 13 acts so that the display plate 11 is attached to the mounting member 1.
By being urged in four directions, the display plate 11 comes into close contact with the mounting member 14 side and the fixed state is maintained, and the display plate 11 is fixed without loosening as shown in FIG.

In order to remove the display plate 11 from the fixed state, the reverse operation is carried out, that is, the lower end portion of the display plate is pulled forward against the elastic force of the fastening material 13 or is pushed down, and the fastening material is pulled. Thirteen
The display plate 11 is separated from the front by the elastic force action of, and the engaged state may be released thereafter. The above-mentioned pulling operation can also be performed with fingers, but a plurality of display boards 11 are arranged side by side,
If there is only a small gap between the upper and lower sides, a thin plate-like jig may be hooked on the end portion through this gap. In addition, the fastening material mounting portion 13 with the fastening core 14 inserted thereinto
In the state where a is mounted on the mounting portion 11d of the display plate 11, the fastening material mounting portion 13a is rotatably mounted in the mounting portion 11d, while the fastening core 13c is locked by the slit 11f. The dressing attachment portion 13a is prevented from slipping off or coming off.

In the above structure, the display plate 11, the locking portion 11b formed on the back side thereof, and the mounting portion 11d have the same length in the extrusion direction when the extruded product is cut. Can be used as it is, but when the usage mode is such that the left and right of the display plate 11 are exposed when the display device is installed, it is desirable that the engagement structure on the back surface be invisible. For that purpose, as shown in FIG. 11, the locking portion 11b and the mounting portion 1 are
The vicinity of the left and right ends of 1d is appropriately cut by lengths X and X, and further, the edge member 14 that fits within the height of both protrusions is provided between the ends of the locking portion 11b and the mounting portion 11d after cutting. It can be fixed. By doing this,
Even if you look between the display panel 11 and the base surface 12 such as a wall or a device substrate, the internal structure is not visible because of the narrow gap between them, and the person who normally sees the surface sees the surface from the front or diagonal direction. Since it is a thing, the back surface of the display board 11 cannot be seen at all,
The end portions of the locking portion 11b and the mounting portion 111b are also completely invisible.

In this case, the mounting member 14 has the locking portion 11b.
It may be formed in such a size that it can be accommodated in the space surrounded by the mounting portion 11d and the left and right edge members 15, 15 (the intermediate portion may be omitted). Even when a plurality of display plates 11 are arranged side by side, the mounting members 14 are accurately formed or fixed so that the display plates 11 arranged side by side can be arranged not only in the vertical direction but also in the horizontal direction. There is an advantage that the display plate 11 can be fixed in an orderly and fixed position without any displacement. If edge frames and the like are arranged on both sides of the display plate 11 so that the left and right sides of the display plate 11 are not exposed, the mounting member 14 may have the same length as the display plate 11, and the back surface of the display plate 11 may be the same. It is not necessary to fix the edge material 15 to the edge. When two or more display plates 11 are arranged side by side in the horizontal direction, the mounting member 14 may have a length of a desired multiple of the display plates 11 or a length close thereto.

FIG. 14 shows an example different from the above, in which protruding edges 21a are formed on the upper and lower sides of an aluminum-made display plate 21, and locking projections 21b are formed on the upper and lower portions of the back surface. An engaging projection 22a that engages with the engaging projection 21b is projected from the surface of the mounting member 22 made of synthetic resin, and the engaging projection 21b and the engaging projection 22a are slightly bent by the pressure in the front-rear direction. It is configured to engage while being deformed, and the elasticity is used to maintain the engaged state.

It is formed so that it can be engaged with the inner side of the lower engaging portion 81b of the display plate 81 in a proper protruding state.

FIG. 17 shows a structure in which the projecting edge portion of FIG. 15 (A) is not formed. The projecting edge portion is not formed above and below the display plate 91, and the upper end is folded back. The dovetail-shaped engaging portions 91a are bent to project in parallel to each other, and engaging portions 92a that engage with the inside are provided in parallel in the vicinity of the upper and lower portions of the mounting member 92.
It is formed by protruding. In this case, the projecting edge portion is not formed, but an example in which the display surface of the display plate is formed as the bulging surface as described above is shown.

The above embodiments are merely examples, and the present invention can take various constitutional forms other than the above.

[0048]

According to the display device of the present invention, since the surface of the display plate having the fastening portion formed on the back side is the bulge surface in the middle with respect to the two opposite sides, the display surface of the display device is formed. Can be three-dimensionalized to enhance the appeal required as a display device. Further, by forming the back surface to be flat, the workability is improved and the texture of the display plate is also improved.

If the fastening portion is formed in the back surface so that the display plate has the projecting edge portion, a gap is formed between the mounting plate and the display plate, and the display plate is slightly floated from the mounting plate. Since it will be installed in the state, the novelty of the appearance of the display board increases. The more the fastening portion is formed inward of the back surface of the display plate, the less visible the fastening portion becomes, and the more preferable the appearance is. Also, if there is a protruding edge on the display board and there is a gap on the back side, when the display boards are placed side by side in a substantially close contact state, individual display boards can be attached and detached independently even in the front-back direction. It will be easier.

If the surface of the display plate is swollen with respect to one opposing side, the sense of deformation due to the swollenness can be given directionality, and the appearance can be made even more preferable. In this case, it is possible to represent the end face shape in which the middle portion is thickly changed on the other opposing sides.

By arranging a plurality of the above-mentioned display plates side by side, the whole display plate becomes a corrugated surface, and the novelty of the appearance can be further enhanced. In addition, if the display plates are juxtaposed, the contour of the display plate becomes clear due to the unevenness of the display surface, and the bulging state of the display surface itself differs for each display plate, so the display for each display plate becomes clearer. It can be identifiable. The display boards can be arranged side by side in close contact with each other. Even when they are arranged side by side with a very small gap, they can be perceived as a good close contact state in appearance. Moreover, the display board can be attached and detached.
