Utility model registration No. 3110515

However, the above-mentioned conventional technology has the following problems. Since it was made of metal, it was a heavy burden to transport due to its weight. They were also highly aggressive toward workers and surrounding objects. Making it a resin would help make it lighter and less aggressive, but it was difficult to provide the necessary strength just by making it a resin.

The present invention has been made to solve the problems of the conventional techniques described above. That is, the objective is to provide a display plate support made of synthetic resin that is lightweight, has low aggressiveness, and has the necessary strength.

The display plate support in each aspect of the present invention is a display plate support made of synthetic resin that is integrally formed by blow molding and supports a flexible display plate, and is located at the bottom of the storage space for the display plate. A plate support wall, a rear wall that is located further away from the plate support wall when viewed from the storage space with a hollow space between the plate support wall, and a rear wall that is placed in a state where the plate support wall is erected against the ground. The plate support wall and the rear wall each have a leg member holding portion that holds the leg member to be maintained so as to be positioned outside the rear wall in a state where the angle can be changed at least by changing the angle or detaching the leg member. , has a frame-shaped part forming a quadrilateral shape when viewed from the front, an intermediate part located at the center of the quadrilateral formed by the frame-shaped part, and a connecting part connecting each corner of the frame-shaped part and the intermediate part. are .

In the display plate support described above , the plate support wall forms the bottom surface of the storage space in which the display plate is stored. A rear wall is disposed further away from the plate support wall when viewed from the storage space, with a hollow space interposed between the rear wall and the plate support wall. Due to the two-piece structure of the plate support wall and the rear wall formed by blow molding, the display plate support of this embodiment achieves both rigidity and lightness. Further, since the plate support wall and the rear wall have a frame-shaped portion, an intermediate portion, and a connecting portion, a window-like portion exists between them. This also contributes to lightness and rigidity.

The display plate support described above can be maintained in a standing state on the ground or floor by attaching the leg members to the leg member holders. The leg member can at least change its angle with respect to the display plate support and attach/detach it. Therefore, space-saving storage is possible by removing the leg members when not in use or by setting them at the angle for storage.

The display plate support according to the first and second aspects of the present invention further includes a groove-shaped depression in at least one wall of the plate support wall and the rear wall of the frame portion toward the other wall. A groove is formed . In this way, by making the plate support wall or the rear wall have an uneven shape rather than a simple flat plate, it contributes to improving the rigidity of the display plate support. Groove wall portions may be formed on both widthwise sides of the depressed groove portion. In the first aspect, the recessed groove portion is provided in the connecting portion in a diagonal direction with respect to the overall shape of the frame portion. In the second aspect, the rear wall has a leg member storage recess that is recessed toward the plate support wall, a vertical wall that is a boundary between the leg member storage recess and other parts, and a leg member that is sandwiched between the vertical wall. A sub-recess is formed adjacent to the storage recess, the leg member holding portion is formed in a portion of the vertical wall sandwiched between the leg member storage recess and the sub-recess, and a recessed groove is provided in the rear wall. In addition, there is a part where the depression groove and the sub-recess are connected, and the sub-recess is a separated part where there is a gap between the plate support wall and the rear wall, and the plate support wall and the rear wall contact each other. It includes at least one of a communication type part. This will further contribute to improving the mounting strength of the leg members and the rigidity of the display plate support. In the first and second aspects, further, a spaced-apart recess in which there is a gap between the plate support wall and the rear wall, and a communication recess in which the plate support wall and the rear wall are in contact are formed in the recess groove. It is preferable that at least the connecting recesses of the spaced-apart recesses and the communicating recesses are formed at a plurality of locations within one recessed groove section, extending between the groove walls on both sides in the width direction. The display plate support is further reinforced by providing the communication recess where the plate support wall and the rear wall are in contact. It is more effective if the connecting recesses are provided discretely at a plurality of locations within the recess groove. It is better if the recessed groove portion is provided in the connecting portion and the intermediate portion.

In the display plate support of the third aspect of the present invention , the rear wall has a leg member storage recess that is recessed toward the plate support wall and does not reach the outer edge of the rear wall , and a leg member storage recess and other parts. A vertical wall part is formed at the boundary between the two parts, and the leg member holding part is formed in a part of the vertical wall part. With this configuration, the leg members can be stored in the leg member storage recesses during storage or transportation. The leg member holding portion can be formed in a vertical wall portion that is a boundary between the leg member storage recess and other parts.

The display plate support of the third aspect also includes a metallic material that can be in a state of protruding from the leg member storage recess and a state of being stored in the leg member storage recess by changing the angle at the leg member holding part. The leg member has a leg member that, when stored in the leg member storage recess, does not protrude from the in-plane direction range defined by the outer edge of the portion of the display plate support other than the leg member, and It does not protrude beyond the thickness direction defined by the plate support wall and rear wall. If the leg members are of a size and shape that do not protrude from the display plate support in the in-plane direction or the thickness direction when stored, even if they are made of a highly hard material such as metal, they will not be used during storage or transportation. etc. have low aggression toward others.

In the display plate support according to the fourth aspect of the present invention , four windows are formed by the frame portion, the intermediate portion, and the connecting portion.

It is also desirable that the display plate support of each of the above embodiments has a corner support portion that covers the front of the corner portion of the storage space. By having the corner support portion, even if the corner support portion of the display plate has an outward curvature tendency, it can be prevented from protruding, and the aggressiveness of the display plate to the outside can be reduced.

According to this configuration, there is provided a display plate support made of synthetic resin that is lightweight, has low aggressiveness, and has the necessary strength.

Embodiments embodying the present invention will be described in detail below with reference to the accompanying drawings. This embodiment embodies the present invention as a display plate support 10 shown in FIGS. 1 and 2. 1 and 2 show a state in which the display plate 1 is attached to the display plate support 10. As shown in FIG. The display plate support 10 shown in FIGS. 1 and 2 includes a main body 2 that houses the display plate 1, and leg members 3 that are located behind the main body 2 and maintain the main body 2 in an upright position. have. In the display plate support 10 shown in FIGS. 1 and 2, a weight 4 is suspended between the main body 2 and the leg members 3 at the lower part. This stabilizes the standing posture of the display plate support 10.

The display plate support 10 can also be in a state in which the display plate 1 is removed. The display plate support 10 in this state is shown in FIG. FIG. 3 shows the front side of the display plate support 10. As shown in FIG. The display plate support 10 can also be in a state where the leg members 3 are housed. The display plate support 10 in this state is shown in FIG. FIG. 4 shows the rear side of the display plate support 10. The leg member 3 is attached to a leg member holding portion 16 in the main body portion 2. The angle of the leg member 3 with respect to the main body 2 is different between the standing position shown in FIGS. 1 and 2 and the stored state shown in FIG. The weight 4 is a separate component independent from the display plate support 10, and is not shown in FIGS. 3 and 4.

As shown in FIGS. 3 and 4, the main body 2 of the display plate support 10 has a rectangular shape that is slightly larger than the display plate 1 as a whole. When the display plate support 10 is viewed from the front side as shown in FIG. 3, side support portions 5 are provided along the edges. A plate support wall 6 is provided inside thereof. The plate support wall 6 is a part that defines the bottom surface of a storage space inside the main body 2 in which the display plate 1 is stored. In other words, the plate support wall 6 faces the back surface of the display plate 1 in the state shown in FIGS. 1 and 2. The plate support wall 6 includes a quadrilateral frame portion 61 along the side support portions 5, an intermediate portion 62 located in the center, and connections connecting each corner of the frame portion 61 and the intermediate portion 62. 63 is included. Due to this shape of the plate support wall 6, four windows 12 are formed in the display plate support 10. Further, a through hole 13 for hanging a weight 4 is formed on the lower end side of the main body portion 2 .

The rear side of the display plate support 10 shown in FIG. 4 is constituted by a rear wall 7. As shown in FIG. The rear wall 7 is a plate-like member separate from the plate support wall 6. The rear wall 7 is located further away than the plate support wall 6 when viewed from the storage space for the display plate 1. The rear wall 7 and the plate support wall 6 are arranged with a hollow space therebetween. Similarly to the plate support wall 6, the rear wall 7 also includes a quadrilateral frame-shaped part 71, an intermediate part 72 located at the center, and a connecting part 73 connecting each corner of the frame-shaped part 71 and the intermediate part 72. Contains.

Therefore, even from the rear side, it can be seen that four windows 12 are provided. In FIG. 2, the back surface of the display plate 1 is visible through the window 12. The structure in which the window 12 is formed by the frame portions 61 and 71, the intermediate portions 62 and 72, and the connecting portions 63 and 73 in this manner also contributes to the lightness and rigidity of the main body portion 2. The through hole 13 on the lower end side is also visible from the rear side. A groove-shaped leg member storage recess 14 is provided in the rear wall 7. The leg member 3 shown in FIGS. 1 and 2 is housed in the leg member storage recess 14 in the state shown in FIG.

The leg member 3 can also be removed from the main body part 2. FIG. 5 shows a state in which the leg member 3 is removed from the state in FIG. 4. Note that both the main body portion 2 and the display plate 1 are made of synthetic resin. In particular, the display plate 1 is made of a material that has some degree of flexibility. The main body portion 2 is formed by blow molding a synthetic resin material into a two-layer structure consisting of the aforementioned rear wall 7 and the plate support wall 6. The leg member 3 may be made of synthetic resin or metal. However, when the leg member 3 is made of synthetic resin, it is preferably made of a harder material than the synthetic resin of the main body part 2.

The front side of the main body part 2 will be further explained with reference to FIG. FIG. 6 is a front view of the main body part 2, the left half shows a state in which the display plate 1 is attached, and the right half shows a state in which the display plate 1 is not attached. Although such a state is rarely used in normal use, if the display plate 1 is cut in half in the left-right direction and dared to be attached to the main body 2, the same state as shown in FIG. 6 will be obtained.

As shown in FIG. 6, the side support portion 5 is provided with discrete drop-off prevention portions 8 that protrude inward. In this embodiment, fall prevention parts 8 are provided at two locations on both long sides of the side support part 5 and at three locations on both short sides. As is clear from the left half of FIG. 6, the drop-off prevention part 8 is located further forward than the display plate 1. In other words, the drop-off prevention part 8 partially covers the front of the display plate 1. This prevents the display plate 1 from falling off.

FIG. 7 shows a part of the main body portion 2 shown in FIG. 5 with a portion cut away. As shown in FIG. 7, a recessed groove portion 26 is formed in the rear wall 7 of the main body portion 2 of the display plate support 10. As shown in FIG. The recessed groove portion 26 is a groove-shaped portion formed by recessing a portion of the rear wall 7 toward the plate support wall 6. The hollow groove portion 26 is formed separately from the leg member storage recess 14. The recessed groove portion 26 is provided in a portion of the rear wall 7 corresponding to the connecting portion 73 in a diagonal direction with respect to the overall shape of the main body portion 2 .

The range indicated by the symbol P in FIG. 7 is shown in FIG. 8 in an enlarged manner. FIG. 8 shows a cross section of the connecting portion 63 and the connecting portion 73 of the main body 2 in a diagonal direction with respect to the overall shape of the main body 2. As shown in FIG. As a result, the internal structure of the recessed groove portion 26 appears in FIG. As shown in FIG. 8, the depression groove 26 includes a spaced depression 27 where there is a gap between the rear wall 7 and the plate support wall 6, and a communication space where the rear wall 7 and the plate support wall 6 are in close contact with each other without a gap. It includes a recessed portion 28. The spaced apart depressions 27 and the communication depressions 28 are arranged alternately in the longitudinal direction of the depression groove 26. In the example of FIG. 8, a plurality of spaced apart depressions 27 and communication depressions 28 are formed in one depression groove 26. The communication recess 28 may be a place where the rear wall 7 and the plate support wall 6 are joined, or the rear wall 7 and the plate support wall 6 are simply in contact but are not joined. It may be a location.

Groove wall portions 29 are formed on both sides of the recessed groove portion 26 in the width direction. The groove wall portion 29 is a vertical wall that connects the recess groove portion 26 (separated recess portion 27 and communication recess portion 28) and a portion of the rear wall 7 other than the recess groove portion 26. Although only one groove wall 29 is visible at the recessed groove 26 in FIG. 8, the groove wall 29 exists on both sides of the recessed groove 26 in the width direction in the main body 2 in its original shape before cutting. ing.

By forming the depression groove portion 26 in this manner, the rigidity of the main body portion 2 is increased. First of all, the fact that the entire main body 2 is composed of two plates, the plate support wall 6 and the rear wall 7, contributes to improving the rigidity of the main body 2 as a whole without increasing the weight. are doing. Therefore, the display plate support 10 can be made relatively lightweight even if the leg members 3 are included. If the display plate support 10 is lightweight, it will not only be easier to work with, but will also be less likely to attack external objects during transportation or storage.

The rear wall 7, which is one of the two walls, is not a simple plane but has an uneven shape (concavities and grooves 26), thereby further improving the rigidity. Furthermore, the rigidity is further improved because a portion of the recessed groove portion 26 is formed into a communicating recessed portion 28 that is in close contact with the plate support wall 6. By providing a plurality of connecting recesses 28 in a plurality of discrete locations within one recess groove 26, the effect of the connecting recess 28 is further increased. Further, by providing such a recessed groove portion 26 in the relatively narrow portion of the connecting portion 73, the contribution to the overall reinforcement of the main body portion 2 is increased. Note that, as shown in FIG. 5, the depression groove portion 26 is provided not only in the connecting portion 73 but also in the intermediate portion 72.

Next, the aforementioned leg member storage recess 14 (FIGS. 4, 5, and 7) will be explained. As seen in FIG. 5, the leg member storage recesses 14 are formed in the frame-shaped parts 71 on both the left and right sides, the frame-shaped part 71 on the lower side, and the intermediate part 72. This is, of course, adapted to the shape of the leg member 3. Here, focusing on the leg member storage recesses 14 formed in the frame-shaped portions 71 on both left and right sides, these leg member storage recesses 14 extend from around the leg member holding portion 16 to near the lower end of the main body 2. It is formed. However, the leg member storage recess 14 does not penetrate into the lower end of the main body 2. No matter where you look at the other parts of the leg member holding part 16, there is no part that reaches the outer edge of the main body part 2. The leg member 3 is, of course, of a shape and size such that it can be completely accommodated in the leg member storage recess 14 when the leg member 3 is in the stored state shown in FIG.

The leg member storage recess 14 may be formed as a spaced type with a gap between the rear wall 7 and the plate support wall 6, or a connected type where the rear wall 7 and the plate support wall 6 are in close contact with each other without a gap. It may also be formed as a mold. In the case of a connecting type, the rear wall 7 and the plate support wall 6 may be joined, or the rear wall 7 and the plate support wall 6 may simply be in contact but not joined. good. It may include both a spaced part and a communicating part.

As shown in the cross-sectional view of FIG. 9, in the main body 2 in the stored state, the leg members 3 are completely accommodated in the leg member storage recess 14, and the legs outwardly extend from the main body 2. There is no part where the member 3 protrudes. In other words, the leg members 3 in the stored state do not protrude from the in-plane direction range defined by the outer edge of the main body 2 of the display plate support 10. Further, it does not protrude from the thickness direction range defined by the plate support wall 6 and the rear wall 7. What is shown in FIG. 9 is a cross section taken along the line AA in FIG. 6, but the same applies to portions along both left and right sides of the leg member 3.

As a result, if the leg members 3 are left in the stored state without being removed, the leg members 3 are less likely to attack external objects when the display plate support 10 is being transported or the like. Furthermore, the attack on the ground or floor surface by the leg members 3 during the work of installing the display plate support 10 is also reduced. When installing the display plate support 10, the leg members 3 in the stored state are pulled out from the leg member storage recesses 14 while the lower side of the display plate support 10 is grounded. At this time, due to the size relationship between the main body 2 of the display plate support 10 and the leg members 3 as described above, it is difficult for the lower ends of the leg members 3 to rub against the ground or floor surface. The same applies when recovering the installed display plate support 10. Note that even the leg member 3 stored in the leg member storage recess 14 is not housed in the hollow space of the main body 2, but is located outside the rear wall 7.

A part of the leg member storage recess 14 is also visible in the enlarged view of FIG. The leg member storage recess 14 is also a groove-shaped portion formed by recessing a portion of the rear wall 7 toward the plate support wall 6. In this respect, it is common to the recessed groove portion 26. Regarding the leg member storage recess 14, a vertical wall portion 30 is also formed at the boundary between the leg member storage recess 14 and a portion of the rear wall 7 other than the leg member storage recess 14. The aforementioned leg member holding portion 16 is a hole formed in the vertical wall portion 30.

FIG. 10 shows a part of FIG. 4 in an enlarged manner. The region shown in FIG. 10 is a portion of the main body portion 2 in FIG. 4 near the upper end of the intermediate portion 72. As shown in FIG. This part partially overlaps with the area P shown in FIG. 8, but is slightly to the upper right of it. However, FIG. 10 shows the main body portion 2 in an uncut state. Further, the leg member 3 is attached to the main body portion 2 shown in FIG. 10 and is in a stored state. As shown in FIG. 10, the leg member 3 is attached to the leg member holding portion 16 by an attachment member 31 so that the angle thereof can be changed. That is, holes are also formed in the leg member 3 at locations corresponding to the holes in the leg member holding portion 16, and the attachment member 31 passes through these holes. When removing the leg member 3 from the main body portion 2, the attachment member 31 may be removed.

Further, as shown in FIG. 10, a sub-recess 32 is provided in a portion of the rear wall 7 adjacent to the leg member holding portion 16. The hole of the leg member holding portion 16 mentioned above projects into the sub-recess 32 on the outside of the leg member storage recess 14. That is, the leg member holding portion 16 is formed in a portion of the vertical wall portion 30 that is sandwiched between the leg member storage recess 14 and the sub-recess 32. The provision of the sub-recess 32 facilitates the work of attaching the leg member 3 using the attaching member 31 and the work of removing the attaching member 31. Further, the vertical wall portion 30 is rib-shaped between the leg member storage recess 14 and the sub-recess 32, and the strength of attaching the leg member 3 by the attachment member 31 is improved. The sub-recesses 32 are provided not only in the one shown in FIG. 10 but also in the leg member storage recess 14 along both left and right sides adjacent to the leg member holding portion 16 (FIG. 5).

As seen in FIG. 10, the sub-recess 32 is connected to the depression groove 26. As a result, the uneven portion of the rear wall 7 is expanded. This further contributes to improving the rigidity of the display plate support 10. The sub-recess 32 connected to the depression groove 26 is provided in the intermediate portion 72.

The sub-recess 32 may be formed as a separated type with a gap between the rear wall 7 and the plate support wall 6, or as a communicating type where the rear wall 7 and the plate support wall 6 are in close contact with each other without a gap. may be formed. In the case of a connecting type, the rear wall 7 and the plate support wall 6 may be joined, or the rear wall 7 and the plate support wall 6 may simply be in contact but not joined. good. It may include both a spaced part and a communicating part.

Returning to FIG. 1, the display plate support 10 of this embodiment is also provided with corner support portions 18. The corner support portion 18 is formed across two adjacent sides of the side support portion 5 . The corner support part 18 is similar to the drop-off prevention part 8 in that it has a shape that partially covers the front of the mounted display plate 1. As shown in FIGS. 4 and 5, if the display plate 1 is not attached, the fall prevention part 8 and the corner support part 18 can be seen even from the back side of the main body part 2. However, when the display plate 1 is attached, as shown in FIG. 11, the fall prevention part 8 and the corner support part 18 are not visible from the back side.

Since the display plate 1 is flexible, it may tend to curve, especially at its corners. By providing the corner support portions 18, even if the corner portions of the display plate 1 have a particular tendency to curve outward, the corner portions of the display plate 1 will not bend forward from the main body portion 2 of the display plate support 10. This prevents it from bulging out to the side. As a result, even when the display plate support 10 is transported with the display plate 1, which has a tendency to curve, attached, the display plate 1 does not attack external objects too much. . In the main body portion 2 of this embodiment, corner support portions 18 are provided at each of the four corners.

As described above in detail, according to the present embodiment, the main body portion 2 of the display plate support 10 is constructed of two pieces, the rear wall 7 and the plate support wall 6, which are formed by blow molding. As a result, by achieving both lightness and high rigidity, a display plate support 10 that has both workability, low aggressivity, and necessary strength is realized. Further, by providing a recess groove 26 in a part of the rear wall 7 and configuring the recess groove 26 with a spaced recess 27 and a connecting recess 28, the rigidity is further increased. A leg member holding portion 16 is provided on the vertical wall portion 30 of the leg member storage recess 14 so that the leg member 3 is completely stored in the leg member storage recess 14 in the stored state. Furthermore, by providing the corner support portions 18, the display plate 1 is prevented from protruding outward even when the display plate 1, which has a tendency to curve, is left attached.

Note that this embodiment is merely an example, and does not limit the present invention in any way. Therefore, the present invention is naturally capable of various improvements and modifications without departing from the spirit thereof. For example, in the above embodiment, the overall shape of the main body portion 2 and the display plate 1 is rectangular. However, the overall shape is not limited to this, and the overall shape is not limited to a rectangle, but may be a square or a trapezoid or other shape.

Further, in the above embodiment, the connecting portion 73 and the intermediate portion 72 are shown as locations where the recessed groove portion 26 is formed, but the recessed groove portion 26 may be formed in the frame-shaped portion 71. Further, the recessed groove portion 26 in the above embodiment was a portion where a portion of the rear wall 7 was recessed toward the plate support wall 6, but conversely, a portion of the plate support wall 6 was recessed toward the rear wall 7. It may be a recessed part. Alternatively, both the rear wall 7 and the plate support wall 6 may be recessed toward the other.

Further, in the above embodiment, the leg member 3 is capable of both changing the angle and attaching and detaching the leg member 3 to the main body portion 2, but it may be possible to change the angle only and not be able to remove it. Furthermore, the standing state may be realized by not having the leg members 3 and by connecting the main body parts 2 to each other. For example, the present invention can be applied to a display device 24 formed by combining two display members 23 as shown in FIG. 12. That is, the two display members 23 are made like the main body part 2 of the above embodiment, and the top part 25 is used as a connecting part (leg member holding part).

In this case, when viewed from each display member 23 (main body portion 2), it can be seen that the other display member 23 plays the role of the leg member 3. In that case, a portion corresponding to the leg member storage recess 14 is unnecessary. Further, the connecting portion in this case may be one that allows only an angle change, or may be one that allows both an angle change and detachment. It is not limited to a vertically long one as shown in FIG. 12, but may be a horizontally long one.
