Description

In the present invention, the display object is inserted from both sides by inserting two transparent plates sandwiching the display object into the opening of the square frame formed by connecting the four frame members with the four corner members. It relates to a visible display panel.

Conventionally, a rectangular back plate, peripheral members attached to the four peripheral sides of the back plate, and other sides are pivotally supported by the peripheral members so that one side faces the back plate, and the other side is used as the center of rotation. The cover member is configured so that one side can be separated from the back plate by rotating, and one side of the cover member comes into contact with the periphery of the display object stacked on the back plate so that the periphery of the display object is pressed against the back plate. A display panel including a spring member for urging each member is disclosed (see, for example, Patent Document 1 (claim 1, paragraph [0008], paragraph [0014], FIGS. 1 to 5)). In this display panel, a stopper that abuts on the upper cover member located on the upper edge of the back plate and prevents the space between one side of the upper cover member and the back plate from being less than the thickness of the display object is provided on the back plate. It is provided on the upper peripheral member attached to the edge. Further, a prohibition member for prohibiting rotation of the upper cover member in contact with the stopper is provided on the upper peripheral member attached to the upper edge of the back plate. Further, the corner member is formed in an arc shape so as to cover the ends of the orthogonal frame members, and a pair of legs protruding from the orthogonal frame members are formed. The legs are inserted into peripheral members of the frame member and attached by screwing means, whereby the corner members are held by the frame member.

In the display panel configured in this way, a stopper that abuts on the upper cover member located at the upper edge of the back plate and prevents the space between one side of the upper cover member and the back plate from being less than or equal to the thickness of the display object. And a prohibition member for prohibiting the rotation of the upper cover member in contact with the stopper are provided on the upper peripheral member attached to the upper edge of the back plate. Insert the upper part and display the display object by pressing the lower edge of the display object and its side edge against the back plate by the lower edge of the back plate and other cover members other than the upper part attached to the side edge thereof. Can be done. Therefore, even if the upper cover member located on the upper edge of the back plate is located at a relatively high place due to the relatively large display object, it is located at a high place when the display object is removed or a new display object is displayed. It is not necessary to open and close the upper cover member, and the display object can be replaced or the display work can be performed relatively easily as compared with the conventional case.

It has flat plate-shaped leaf springs 11s and 12s installed in a curved state, and the leaf springs 11s and 12s are used when the cover members 11i and 12i rotate from a fixed position to an insertion position or the cover members 11i and 12i. Is installed so that the radius of curvature of the leaf springs 11s and 12s becomes smaller and larger again when the leaf springs 11s and 12s rotate from the insertion position to the fixed position, and when the cover members 11i and 12i are located at the insertion position, the cover members 11i and 12i The leaf springs 11s and 12s are temporarily fixed to the insertion position, and when the cover members 11i and 12i are located at the fixed positions, the tips of the cover members 11i and 12i are pressed against the transparent plate 17 by the leaf springs 11s and 12s. It is characterized by being configured.

In the display panel according to the first aspect of the present invention, a square frame is formed by connecting four frame members with four corner members, and two pieces sandwiching a display object in the opening of the square frame. Since the transparent plate of is inserted, the displayed object can be visually recognized from both sides of the square frame. As a result, the amount of information displayed on the display panel can be doubled as compared with the conventional display panel, or the same information can be visually recognized by many people. Further, by inserting the protrusion of the corner member into the protrusion insertion portion of the frame member, it becomes easy to match the outer shape at the connection portion between the corner member and the frame member. As a result, it is possible to suppress the occurrence of a step in the outer shape at the connection portion between the corner member and the frame member, so that the appearance can be improved as compared with the conventional display panel. Further, by rotating the cover member from the fixed position to the insertion position, it is possible to replace the display object for both sides (two sides) from the cover member side of the display panel. As a result, for example, when the display panel is erected in the show window of the store and installed so that the displayed contents can be visually recognized from inside and outside the store, the display panel does not enter the narrow space between the glass of the show window and the display panel. , The display can be easily exchanged from inside the store.
Further, in the display panel according to the first aspect of the present invention, since the cover member and the bulging portion are formed so as to be substantially plane-symmetrical with respect to the transparent plate, the shapes of the frame members on both surfaces are substantially the same. Therefore, the design of both sides of the square frame can be improved.

In the display panel according to the second aspect of the present invention, the protrusion is inserted into the protrusion insertion portion by screwing the screw inserted into the through hole of the frame member into the screw hole formed in the protrusion of the corner member. It is fixed with screws in the state. As a result, it is possible to reliably prevent the frame member and the corner member from separating. Further, since the through hole is formed on the surface of the protrusion insertion portion of the frame member that is opened and closed by the cover member, when the cover member is positioned at the insertion position, the screw can be screwed into the screw hole with a tool, and the cover can be used. When the member is positioned at a fixed position, the head of the screw is covered with the cover member so that it cannot be seen, and the appearance can be improved.

In the display panel according to the third aspect of the present invention, when the display object is a single sheet printed and displayed on both sides, the information displayed on both sides can be changed by simply exchanging one sheet. Further, in the case of two sheets having the same or different print display on one side and an opaque plate interposed between them, if one of the two sheets is replaced, it will be displayed on one side. You can change only the information displayed on both sides, and if you exchange both sheets, you can change the information displayed on both sides.

In the display panel according to the fourth aspect of the present invention, when the cover member rotates from the fixed position to the insertion position, the radius of curvature of the leaf spring becomes smaller and becomes larger again, but the cover member is positioned at the insertion position. Since the leaf spring is still kept curved, the cover member is temporarily fixed at the insertion position by the leaf spring. As a result, the displayed object can be easily exchanged. Also, when the cover member rotates from the insertion position to the fixed position, the radius of curvature of the leaf spring becomes smaller and larger again, but the leaf spring is still kept curved while the cover member is located at the fixed position. Therefore, the tip of the cover member is pressed against the transparent plate by the leaf spring. As a result, even if some external force is applied to the display panel, the display object or the transparent plate does not unintentionally fall off from the square frame.

<First Embodiment>
As shown in FIGS. 1, 2 and 5, the display panel 10 is formed by connecting four frame members 11 and 12 with four corner members 13 to form a square frame body 14. By inserting the two transparent plates 17 and 17 sandwiching the display object 16 into the opening 14a of the square frame body 14, the display object 16 can be visually recognized from both sides of the square frame body 14. The four corner members 13 are formed to have the same shape and size (FIGS. 5 and 6). Each corner member 13 is projected from the corner main body 13a, which is formed in a fan shape of about a quarter circle and has a pair of planes forming an angle of about 90 degrees, and the pair of planes of the corner main body 13a, respectively. It has a pair of protrusions 13b and 13b (FIG. 3). The outer shape of the corner body 13a approximates one shape of a toy yo-yo divided into four by two orthogonal planes including its central axis (FIGS. 5 and 6). Further, the pair of protrusions 13b, 13b are a protrusion main body 13c formed in a substantially rectangular rod shape, and a protrusion portion 13d that extends in the longitudinal direction on the lower surface of the protrusion main body 13c and is narrower than the protrusion main body 13c. (Figs. 3 and 4). Further, a screw hole 13e is formed through the side surface of the protrusion body 13c. The corner member 13 is formed by injection molding of an alloy mainly composed of a light metal such as an aluminum alloy, a magnesium alloy, a titanium alloy, and a beryllium alloy, or is made of an ABS (Acrylonitrile Butadiene Styrene) resin or ASA (Acrylate Sthrene Acrylonitrile). It is preferably formed by subjecting electroless plating after injection molding of a plastic such as a resin or a polycarbonate resin.

On the other hand, the cross-sectional shapes of the four frame members 11 and 12 are formed to have the same shape and size (FIGS. 1 and 2). Further, in this embodiment, of the four frame members 11 and 12, the two frame members 11 and 11 arranged horizontally in parallel with each other are the two frame members 12 arranged vertically in parallel with each other. , 12 is formed shorter (Fig. 5). Further, each of the frame members 11 and 12 is provided integrally with the side receiving portions 11a and 12a that receive the outer peripheral side surface of the transparent plate 17 and the side receiving portions 11a and 12a, and the end surface receiving portions that receive the outer peripheral end surface of the transparent plate 17. 11b, 12b, protrusion insertion portions 11c, 12c formed in a substantially C-shaped channel having a substantially C-shaped cross section with the end face bearing portions 11b, 12b as inner walls 11e, 12e, and protrusions 13c, and the protrusions can be inserted. Of the portions 11c and 12c, the shaft portions 11g and 12g provided along the outer walls 11f and 12f facing the inner walls 11e and 12e forming the end face receiving portions 11b and 12b and protruding outward, and the shaft portions 11g and 12g. The cover members 11i and 12i are formed with bearing portions 11h and 12h rotatably fitted into the transparent plate 17 and can cover the periphery of the transparent plate 17 and the display object 16, and the tips of the cover members 11i and 12i are displayed as the transparent plate 17 and the display . It has urging mechanisms 11j and 12j that press against the object 16 (FIGS. 1 and 2).

The side surface receiving portions 11a and 12a and the end surface receiving portions 11b and 12b are provided orthogonally to each other (FIGS. 1 and 2). Further, the cross-sectional shape of the protrusion insertion portions 11c and 12c is formed so as to correspond to the cross-sectional shape of the protrusion main body 13c and the ridge portion 13d of the protrusion 13b of the corner member 13. As a result, the protrusion body 13c and the protrusion 13d can be inserted into the protrusion insertion portions 11c and 12c without rattling (FIGS. 3 and 4). Further, of the pair of side walls 11k and 11m forming the protrusion insertion portion 11c, one side wall 11k facing the cover member 11i faces the screw hole 13e with the protrusion 13b inserted in the protrusion insertion portion 11c. A through hole 11n through which the screw 18 can be inserted is formed (FIG. 4). Of the protrusion insertion portions 11e and 12e, hanging metal fittings for suspending the display panel 10 or leg parts for supporting the display panel are inserted into the outer walls 11f and 12f facing the inner walls 11e and 12e forming the end face receiving portions 11b and 12b. Possible slits 11d, 12d are formed (FIGS. 1 and 2). In this embodiment, the shaft portions 11g and 12g are provided along the connection portion between the outer walls 11f and 12f and the one side wall portions 11k and 12k and projecting outward. Further, the bearing portions 11h and 12h rotatably fitted into the shaft portions 11g and 12g are provided along the base end edges of the cover members 11i and 12i. Then, with the bearing portions 11h and 12h fitted into the shaft portions 11g and 12g, the cover members 11i and 12i have an insertion position where the transparent plate 17 and the display object 16 can be inserted into the opening portion 14a of the square frame body 14. With the transparent plate 17 and the display object 16 inserted in the opening 14a, the transparent plate 17 and the display object 16 are rotatably configured at a fixed position to be fixed. The end edges of the bearing portions 11h and 12h abut on the necks of the shaft portions 11g and 12g, so that the tips of the cover members 11i and 12i rotate in a direction further away from the transparent plate 17 and the display object 16 from the insertion position. It is designed not to be used (FIGS. 1 (a) and 2).

The cover members 11i and 12i are formed by bulging outward while covering the periphery of the transparent plate 17 and the display object 16 (FIGS. 1 and 2). Further, the edge of the side receiving portions 11a and 12a of the frame members 11 and 12 and the outer walls 11f and 12f facing the inner walls 11e and 12e forming the end face receiving portions 11b and 12b bulge outward. It is connected by 11p and 12p. Specifically, the end edges of the side receiving portions 11a and 12a and the other side edges of the slits 11d and 12d of the outer walls 11f and 12f are connected by the bulging portions 11p and 12p that bulge outward. Then, the cover members 11i and 12i and the bulging portions 11p and 12p are formed so as to be substantially plane-symmetrical with respect to the transparent plate 17. As a result, the shapes of the square frame 14 on both sides become substantially the same, and the designability of both sides of the square frame 14 can be improved. The frame members 11 and 12 are formed by extrusion molding of an alloy mainly composed of a light metal such as an aluminum alloy, a magnesium alloy, a titanium alloy, and a beryllium alloy, or are formed of a vinyl chloride resin, a polycarbonate resin, or PET (PolyEthylene Terephthalate). It is preferably formed by electroless plating after extrusion molding of a plastic such as a resin. When the frame members 11 and 12 are formed by extrusion molding of an aluminum alloy, it is desirable to perform anodizing treatment (anodizing treatment) after extrusion molding. Further, in this embodiment, the display object 16 is a single sheet that is printed on both sides and the printed display on the back side cannot be seen through from the front side. Further, examples of the transparent plate 17 include a transparent acrylic plate, a vinyl chloride plate, and a polycarbonate plate.

The urging mechanisms 11j and 12j include hooks 11q and 12q formed on the tip edges of the cover members 11i and 12i, and concave grooves 11r and 12r formed in the vicinity of the shaft portions 11g and 12g of the protrusion insertion portions 11c and 12c. It has flat plate-shaped leaf springs 11s and 12s installed in a curved state between the hooks 11q and 12q and the concave grooves 11r and 12r (FIGS. 1 and 2). The leaf springs 11s and 12s are arranged substantially at the center of the four frame members 11 and 12 in the longitudinal direction (FIG. 5). Further, the leaf springs 11s and 12s have a radius of curvature of the leaf springs 11s and 12s when the cover members 11i and 12i rotate from the fixed position to the insertion position or when the cover members 11i and 12i rotate from the insertion position to the fixed position. Is installed so that it becomes smaller and larger again (FIGS. 1 and 2). However, when the cover members 11i and 12i are located at the insertion position or the fixed position, the leaf springs 11s and 12s are still kept in a curved state. Therefore, when the cover members 11i and 12i are positioned at the insertion position, the cover members 11i and 12i are temporarily fixed at this position by the leaf springs 11s and 12s, and when the cover members 11i and 12i are located at the fixed position. The tips of the cover members 11i and 12i are configured to be pressed against the transparent plate 17 by the leaf springs 11s and 12s.

The method of assembling the display panel 10 configured in this way will be described. First, of the protrusion insertion portions 11c and 12c of the frame members 11 and 12, the shaft portion 11g provided along the outer walls 11f and 12f facing the inner walls 11e and 12e forming the end face receiving portions 11b and 12b and projecting outward. , 12h, after the bearing portions 11h and 12h of the cover members 11i and 12i are fitted, both ends of the flat plate-shaped leaf springs 11s and 12s are hooked 11q and 12q of the cover members 11i and 12i and the concave grooves in the vicinity of the shaft portions 11g and 12g. It is locked to 11r and 12r, respectively. Then, the cover members 11i and 12i are temporarily fixed at the insertion positions. At this time, since the leaf springs 11s and 12s are still kept in a curved state, the cover members 11i and 12i are temporarily fixed to the insertion positions by the leaf springs 11s and 12s. Next, the protrusion 13b of the corner member 13 is inserted into the protrusion insertion portions 11c and 12c of the frame members 11 and 12 to assemble the square frame body 14 (FIGS. 5 and 6). At this time, since it becomes easy to match the outer shape at the connection portion between the corner member 13 and the frame members 11 and 12, it is possible to suppress the occurrence of a step in the outer shape at the connection portion between the corner member 13 and the frame members 11 and 12, and the conventional display can be suppressed. The appearance can be improved compared to the panel. Next, the screw 18 is inserted into the through hole 11n formed in one of the side walls 11k and 12k of the frame members 11 and 12, and then screwed into the screw hole 13e formed in the protrusion 13b of the corner member 13 (FIG. 3). And FIG. 4). At this time, since the cover members 11i and 12i are temporarily fixed at the insertion position and the through hole 11n is exposed, the screw 18 can be easily inserted into the through hole 11n using a tool (driver) and the screw hole 13e. Can be screwed into (Fig. 4). Further, since the protrusion 13b is fixed by the screw 18 while being inserted into the protrusion insertion portions 11c and 12c, it is possible to reliably prevent the frame members 11 and 12 and the corner member 13 from separating.

Further, after inserting the single display object 16 printed and displayed on both sides into the opening 14a of the square frame 14 in a state of being sandwiched between the two transparent plates 17 and 17, the cover members 11i and 12i are shown in FIG. Rotate from the insertion position shown by the solid line in (a) and FIG. 2 to the fixed position shown by the solid line in FIG. 1 (b) and the alternate long and short dash line in FIG. 2, respectively. At this time, since the leaf springs 11s and 12s are still kept in a curved state, the tips of the cover members 11i and 12i are pressed against the transparent plate 17 by the leaf springs 11s and 12s. As a result, even if some external force is applied to the display panel 16, the display object 16 and the transparent plate 17 do not unintentionally fall off from the square frame body 14. Further, since the display object 16 can be visually recognized from both sides of the square frame 14, the amount of information displayed on the display panel 10 can be doubled as compared with the conventional display panel, or the same information can be visually recognized by many people. Further, by locating the cover members 11i and 12i at fixed positions, the head of the screw 18 is covered with the cover members 11i and 12i and becomes invisible, so that the appearance can be improved (FIG. 5).

On the other hand, when exchanging the display object 16, first, the cover members 11i and 12i are drawn from the fixed positions shown by the solid line of FIG. 1 (b) and the two-dot chain line of FIG. After rotating to the insertion positions shown respectively, the two transparent plates 17 and 17 sandwiching the display object 16 are taken out from the opening 14a of the square frame body 14. Next, in a state where another display object 16 is sandwiched between the two transparent plates 17 and 17, the cover members 11i and 12i are inserted into the opening 14a of the square frame body 14, and then the cover members 11i and 12i are shown in FIGS. 1A and 2A. Rotate from the insertion position shown by the solid line of FIG. 1 to the fixed position shown by the solid line of FIG. 1 (b) and the two-dot chain line of FIG. 2, respectively. As a result, the display object 16 for both sides (two sides) can be replaced from the cover members 11i and 12i side of the display panel 10. As a result, for example, when the display panel 10 is erected in the show window of the store and installed so that the displayed contents can be visually recognized from inside and outside the store, the display panel 10 enters a narrow space between the glass of the show window and the display panel 10. The display object 16 can be easily exchanged from the inside of the store without any problem. Further, since the display object 16 is a single sheet printed and displayed on both sides, the information displayed on both sides can be changed by simply exchanging one sheet.

<Second embodiment>
