As mentioned above, resin-framed glass sheets have a resin frame formed around the glass sheet. Therefore, if the resin frames come into contact with each other during transport of the resin-framed glass sheets and force is applied to the resin frame, the resin frame may be deformed. If the resin frame is deformed in this way, the resin-framed glass sheets become defective products. To solve this problem, conventionally, when shipped from the factory, the glass sheets are individually wrapped in polyethylene sheets and then stored in storage means such as cardboard together with cushioning material.

However, if the resin-framed glass plates are individually wrapped and then stored in a storage means, there is a problem that the storage work becomes cumbersome. In addition, Patent Documents 1 and 2 disclose techniques for storing a large number of glass plates easily and in a short time, but even if these techniques are used, the storage work cannot be sufficiently simplified.

In view of the above problems, the object of the present invention is to provide a glass plate storage device that can simplify storage operations.

A glass plate storage device according to one aspect of the present invention is a glass plate storage device for storing a resin-framed glass plate, and includes a support section extending in the vertical direction, and a plurality of shelves each fixed to the support section and arranged so as to be spaced apart from one another in the vertical direction. A first cushioning material is attached to the upper surface of each of the shelves, and a second cushioning material is attached to the lower surface of each of the shelves. Each of the shelves is fixed to the support section so as to be rotatable about a pivot axis between a first state, which is a horizontal state, and a second state, which is a flipped-up state. The resin-framed glass plate is stored by arranging the resin-framed glass plate between the first cushioning material and the second cushioning material between the shelves.

In the above-mentioned glass plate storage device, the resin-framed glass plate may be placed on the first cushioning material of the shelf plate in the first state, and then the next shelf plate may be changed from the second state to the first state, thereby storing the resin-framed glass plate between the shelves.

In the above-mentioned glass plate storage device, the resin-framed glass plate may have a fixing device attached to one of its main surfaces, and the resin-framed glass plate may be placed on the shelf so that the fixing device faces the first cushioning material, and the fixing device may be configured to abut against the first cushioning material.

In the above-mentioned glass plate storage device, a third cushioning material is attached to the upper surface of the shelf plate, and the resin-framed glass plate may be positioned so that the main surface of the resin-framed glass plate to which the fixing device is attached abuts against the third cushioning material.

In the above-mentioned glass plate storage device, the resin-framed glass plate may be positioned so that the main surface of the resin-framed glass plate opposite the main surface to which the fixing device is attached abuts against the second cushioning material.

In the above-mentioned glass plate storage device, the shelf may be rectangular in shape when viewed from above, one end side of the rectangular shelf may be fixed to the support portion, a spacer may be provided on the other end side opposite to the one end side of the rectangular shelf, and when each shelf is in the first state, the spacers provided on each shelf may abut against each other to form a space between each shelf for storing the resin-framed glass plate.

In the above-mentioned glass plate storage device, the shelf may be constructed using a frame body and a plate-shaped member that can be inserted by sliding into the frame body.

In the above-mentioned glass plate storage device, the shelf may be changed from the second state to the first state by sliding and inserting the plate-shaped member into the frame body in the second state.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
First, a resin-framed glass plate to be stored in a glass plate storage device according to the present embodiment will be described. Fig. 1 is a plan view showing an example of a resin-framed glass plate. Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1.

1 and 2, the resin-framed glass plate 100 includes a glass plate 101 and a resin frame 102. The resin-framed glass plate 100 is a glass plate 101 to which a resin frame such as polyvinyl chloride or polyurethane is attached in advance. The resin-framed glass plate 100 is attached to an opening in the vehicle body by applying adhesive to the periphery of the main surface facing the vehicle interior when the glass plate 100 is attached to the vehicle. Then, a fixing device 103 is formed on the main surface facing the vehicle interior when the resin-framed glass plate 100 is attached to the vehicle so that the position of the resin-framed glass plate 100 does not shift before the adhesive applied to the resin-framed glass plate 100 hardens (see FIG. 2). The fixing device 103 is formed so as to protrude from the main surface of the resin-framed glass plate 100. In the example shown in FIG. 1, the fixing device 103 is formed at three points on the periphery of the resin-framed glass plate 100.

The resin-framed glass plate 100 shown in Figures 1 and 2 is an example, and the glass plate storage device according to this embodiment may store resin-framed glass plates having shapes other than those shown in Figures 1 and 2.

In the resin-framed glass plate 100 shown in FIG. 1, the glass plate 101 is formed in a substantially quadrangular (trapezoidal) shape in plan view. However, the shape of the glass plate 101 is not limited to a substantially quadrangular shape, and may be a substantially triangular shape, etc. The glass plate 101 may be inorganic glass or organic glass. As the inorganic glass, for example, soda-lime glass, aluminosilicate glass, borosilicate glass, alkali-free glass, quartz glass, etc. are used without any particular limitation. Among these, soda-lime glass is particularly preferable from the viewpoint of manufacturing cost and formability. The forming method of the glass plate 101 is not particularly limited. For example, in the case of inorganic glass, a glass plate formed by a float method or the like is preferable.
When the glass plate 101 is inorganic glass, the glass plate 101 may be either untempered glass or tempered glass. Untempered glass is obtained by forming molten glass into a plate shape and slowly cooling it. Tempered glass is obtained by forming a compressive stress layer on the surface of untempered glass, and may be either air-cooled tempered glass or chemically tempered glass.

When the tempered glass is physically tempered glass (e.g., air-cooled tempered glass), the glass surface may be strengthened by generating a compressive stress layer on the glass surface due to the temperature difference between the glass surface and the inside of the glass by an operation other than slow cooling, such as rapidly cooling the glass plate uniformly heated during bending from a temperature near the softening point. When the tempered glass is chemically tempered glass, the glass surface may be strengthened by generating a compressive stress on the glass surface by an ion exchange method or the like after bending. In addition, glass that absorbs ultraviolet or infrared rays may be used as the glass plate 101. The glass plate 101 is preferably transparent, but may be a glass plate that is colored to the extent that transparency is not impaired.

The glass sheet 101 may have a curved shape such that the outside of the vehicle is convex when it is installed in a vehicle. The glass sheet 101 may have a single curved shape bent in only one direction, or may have a compound curved shape bent in two directions (for example, a specific direction and a direction perpendicular to the specific direction). Gravity forming, press forming, roller forming, or the like is used to bend the glass sheet 101. When the glass sheet 101 is bent to a specific curvature, the radius of curvature of the glass sheet 101 may be 1,000 to 100,000 mm.

The glass plate 101 may be a single glass plate, or may be, for example, laminated glass in which two or more glass plates are bonded together via an interlayer film. As the interlayer film of the laminated glass, a known thermoplastic resin film such as polyvinyl butyral (PVB) or ethylene vinyl acetate copolymer resin (EVA) is used. The interlayer film of the laminated glass may be transparent or may be a colored interlayer film. The interlayer film may also be two or more layers.

When the glass plate 101 is a laminated glass, the thickness of the glass located on the outside and the thickness of the glass located on the inside when the glass plate 101 is attached to a vehicle may be the same or different. When the glass plate 101 is attached to a vehicle, the thickness of the glass located on the outside is preferably 1.0 mm or more and 3.0 mm or less. When the thickness of the glass plate located on the outside is 1.0 mm or more, the strength of the performance such as flying stone resistance is sufficient, and when it is 3.0 mm or less, the mass of the laminated glass does not become too large, which is preferable in terms of fuel efficiency of the vehicle. The thickness of the glass plate located on the inside is preferably 0.3 mm or more and 2.3 mm or less. When the thickness of the glass plate located on the inside of the vehicle is 0.3 mm or more, the handling property is good, and when it is 2.3 mm or less, the mass does not become too large. When the thickness of the glass located on the outside and the thickness of the glass located on the inside are each 1.8 mm or less, it is preferable that the weight reduction and sound insulation of the glass plate 101 can be achieved at the same time. In addition, when the thickness of the glass located on the inside is 1.0 mm or less, the glass located on the inside may be chemically strengthened glass. When the glass located on the inside is chemically strengthened glass, it is preferable that the compressive stress value of the glass surface is 300 MPa or more, and the depth of the compressive stress layer is 2 μm or more.

When the glass plate 101 is a single glass plate, it is preferable that the glass plate 101 is air-cooled tempered glass, and in this case, it is preferable that the thickness of the glass plate 101 is 1.0 mm or more and 5.0 mm or less.

When the glass plate 101 is made of organic glass, examples of the material for the organic glass include transparent resins such as polycarbonate or acrylic resin (e.g., polymethyl methacrylate).

The glass plate 101 may have a shielding layer on the periphery of the surface on the inside of the vehicle. The shielding layer is formed, for example, by applying a ceramic color paste containing a fusible glass frit containing a black pigment and then firing it. This can prevent the adhesive applied to the glass plate 101 from being deteriorated by ultraviolet rays. In addition, various suitable films may be formed on the main surface of the glass plate 101 from the viewpoint of improving weather resistance and functionality such as hydrophilicity and water repellency.

The resin frame 102 is provided so as to surround the periphery of the glass plate 101, for example. Examples of materials for the resin frame 102 include synthetic resins such as polyvinyl chloride (PVC) and thermoplastic elastomer (TPE). The resin frame 102 may be provided around the periphery of the glass plate 101 by mounting the glass plate 101 in a mold having a cavity corresponding to the shape of the glass plate 101 and injecting the above-mentioned synthetic resin (molten synthetic resin) into the cavity. Alternatively, the resin frame 102 formed separately from the glass plate 101 may be fitted to the outer periphery of the glass plate 101.

When the resin frame 102 is integrally formed around the glass plate 101 by injection molding, the glass plate 100 with the resin frame may be an integrally molded product in which the glass plate 101, the resin frame 102, and the fixing device 103 are integrally molded, or a separately prepared fixing device 103 may be attached to the glass plate 100 with the resin frame.

Next, the glass plate storage device according to the present embodiment will be described. Figures 3 and 4 are a cross-sectional view and a front perspective view, respectively, showing the glass plate storage device according to the present embodiment. As shown in Figures 3 and 4, the glass plate storage device 1 according to the present embodiment includes a support portion 10 extending in the vertical direction (z-axis direction) and a plurality of shelves 11.

The support portion 10 supports a number of shelves 11. Specifically, the support portion 10 is rectangular, is provided at both ends of the flat shelf portion 11 in the y-axis direction (see FIG. 4), and supports the negative side of the shelf portion 11 in the x-axis direction. The support portion 10 is made of, for example, a metal material.

The multiple shelves 11 are each fixed to the support 10 and are arranged so as to be spaced apart from each other in the vertical direction (z-axis direction). Each shelf 11 is fixed to the support 10 so as to be rotatable about a pivot 15 between a horizontal state (first state) and a flipped-up state (second state). In other words, each shelf 11 can be in two states: a horizontal state (see shelf 11a in FIG. 3) and a flipped-up state (see shelf 11b in FIG. 3). In this specification, a shelf in a horizontal state is referred to as shelf 11a, a shelf in a flipped-up state is referred to as shelf 11b, and shelves 11a and 11b are collectively referred to as shelf 11.

As shown in FIG. 4, a spacer 16 is provided at the end (both ends) of each shelf board 11 on the positive side in the x-axis direction. In this way, by providing the spacer 16 on each shelf board 11, a space can be formed between each shelf board 11. In other words, when each shelf board 11 is in a horizontal position, the spacers 16 of each shelf board 11 abut against each other in the vertical direction, forming a space between each shelf board 11.

A first cushioning material 12 is attached to the upper surface of each shelf 11. A second cushioning material 13 is attached to the lower surface of each shelf. When a resin-framed glass plate 100 is stored between each shelf 11, the first cushioning material 12 is located on the main surface side (below the resin-framed glass plate 100) where the fixing device 103 of the resin-framed glass plate 100 is attached, and the second cushioning material 13 is located on the opposite side (upper side of the resin-framed glass plate 100) from the main surface where the fixing device 103 of the resin-framed glass plate 100 is attached (see FIG. 6). In other words, in the glass plate storage device 1 according to this embodiment, the resin-framed glass plate 100 is stored between each shelf 11 by arranging the resin-framed glass plate 100 between the first cushioning material 12 and the second cushioning material 13 (see FIG. 6).

In this embodiment, it is preferable that the resin frame 102 attached around the glass plate 101 does not touch the shelf plate 11 to which the first cushioning material 12 is attached. If the resin-framed glass plate 100 has a curved shape such that the side opposite to the main surface to which the fixing device 103 is attached is convex, or if the resin frame 102 has a protrusion, there is a risk that the resin frame 102 will be deformed if it comes into contact with the shelf plate 11. Therefore, it is preferable that the first cushioning material 12 has a height that prevents the resin frame 102 from coming into contact with the shelf plate 11 even when a resin-framed glass plate 100 that has a curved shape or a protrusion is placed.

In this embodiment, it is preferable to omit the first cushioning material 12 from the shelf board 11 located in the top layer of each shelf board 11, and to omit the second cushioning material 13 from the shelf board 11 located in the bottom layer. The first cushioning material 12 and the second cushioning material 13 may be attached to the shelf board 11 using known double-sided tape, adhesive, hook-and-loop fasteners, or the like, or may be directly attached by fitting them to the shelf board 11.

The first cushioning material 12 and the second cushioning material 13 may be made of foamed resin such as urethane foam, polyethylene foam, or polystyrene foam. The first cushioning material 12 and the second cushioning material 13 may be made of the same material or different materials.

The arrangement of the first and second cushioning materials 12 and 13 can be changed as appropriate depending on the shape of the resin-framed glass plate 100. The first and second cushioning materials 12 and 13 may be configured to be removable from the shelf 11. If the first and second cushioning materials 12 and 13 are configured to be removable, when the type of resin-framed glass plate 100 to be stored is changed, the arrangement of the first and second cushioning materials 12 and 13 can be easily changed depending on the shape of the resin-framed glass plate 100 after the change. This allows the first and second cushioning materials 12, 13, and the shelf 11 to be reused.

Figure 5 is a plan view showing an example of the configuration of the shelf 11 provided in the glass plate storage device according to this embodiment. As shown in Figure 5, the shelf 11 is configured using a frame body 21 and a plate-shaped member 22. A first cushioning material 12 is attached to the upper surface of the plate-shaped member 22. For example, the frame body 21 can be configured using a strong metal material. Also, the plate-shaped member 22 can be configured using a flexible resin material. When a resin material is used for the plate-shaped member 22, the plate-shaped member 22 can bend in the vertical direction, thereby absorbing vertical impacts on the resin-framed glass plate 100.

For example, the plate-shaped member 22 is configured to be slidably inserted into the frame body 21. Specifically, the plate-shaped member 22 is inserted from the positive side of the x-axis direction of the frame body 21, and then slid to the negative side of the x-axis direction to attach the plate-shaped member 22 to the frame body 21. For example, by sliding the plate-shaped member 22 into the frame body 21 in a flipped-up state, the shelf board 11 may be caused to move from a flipped-up state to a horizontal state due to the weight of the plate-shaped member 22.

Next, the state in which a resin-framed glass plate 100 is stored in the glass plate storage device 1 according to the present embodiment will be described with reference to Figs. 6 to 8. Figs. 6 and 7 are a cross-sectional view and an enlarged cross-sectional view showing the state in which a resin-framed glass plate 100 is stored in the glass plate storage device 1 according to the present embodiment. As shown in Fig. 6, the glass plate storage device 1 according to the present embodiment has a space formed between each shelf plate 11, and each resin-framed glass plate 100 is stored in the space formed between each shelf plate 11. At this time, each resin-framed glass plate 100 is disposed between the first cushioning material 12 and the second cushioning material 13.

Specifically, as shown in the enlarged cross-sectional view of FIG. 7, a fixing device 103 is provided on the underside of the resin-framed glass plate 100, and when the resin-framed glass plate 100 is placed on the first cushioning material 12, the fixing device 103 of the resin-framed glass plate 100 is placed so as to abut against the first cushioning material 12. In this way, by placing the fixing device 103 of the resin-framed glass plate 100 so as to abut against the first cushioning material 12, it is possible to prevent the resin-framed glass plate 100 from being displaced in the horizontal direction (xy plane direction) during transportation.

For example, a hole (not shown) may be formed on the upper surface of the first cushioning material 12 at a position corresponding to the fixing device 103 of the resin-framed glass plate 100. In other words, by arranging the fixing device 103 of the resin-framed glass plate 100 so that it can be inserted into the hole (not shown) formed on the upper surface of the first cushioning material 12, it is possible to more reliably prevent the resin-framed glass plate 100 from shifting in position during transportation.

In addition, in this embodiment, as shown in the enlarged cross-sectional view of FIG. 7, the upper surface of the resin-framed glass plate 100 may be in contact with the second cushioning material 13. In other words, by sandwiching and fixing the resin-framed glass plate 100 between the first cushioning material 12 and the second cushioning material 13, it is possible to suppress the positional shift of the resin-framed glass plate 100 during transportation. In addition, in this embodiment, a small gap may be formed between the upper surface of the resin-framed glass plate 100 and the second cushioning material 13. In addition, in this embodiment, the second cushioning material 13 may be in contact with the upper surface of the resin-framed glass plate 100 so that the thickness of the second cushioning material 13 after deformation is about 80% to 99% of the original thickness. In this way, it is possible to more reliably suppress the positional shift of the resin-framed glass plate 100 during transportation.

Figure 8 is an enlarged cross-sectional view showing another example of the state in which a resin-framed glass plate 100 is stored in the glass plate storage device 1 according to this embodiment. As shown in Figure 8, in this embodiment, the bottom surface of the resin-framed glass plate 100 (the surface to which the fixing device 103 is attached) may be made to abut against the third cushioning material 14. That is, when storing the resin-framed glass plate 100, the fixing device 103 may be made to abut against the first cushioning material 12, and the bottom surface of the resin-framed glass plate 100 (i.e., the surface other than the position where the fixing device 103 is provided) may be made to abut against the third cushioning material 14.

In addition, in this embodiment, as shown in the enlarged cross-sectional view of FIG. 8, multiple second cushioning materials 13 may be in contact with the upper surface of the resin-framed glass plate 100. In this case, the positions of the first cushioning material 12 and the third cushioning material 14 (positions of the lower cushioning materials) and the position of the second cushioning material 13 (position of the upper cushioning material) in the vertical direction (z-axis direction) may be shifted from each other. With this configuration, it is possible to effectively prevent the resin-framed glass plate 100 from shifting in position during transportation.

In the above-mentioned configuration example, the case where the fixing device 103 is provided on the resin-framed glass plate 100 has been described, but the glass plate storage device 1 according to the present embodiment can also store a resin-framed glass plate 100 that does not have the fixing device 103. In this case, the bottom surface of the resin-framed glass plate 100 (preferably any multiple points) is abutted against the first cushioning material 12, and the second cushioning material 13 is abutted against the top surface of the resin-framed glass plate 100. In other words, in this case as well, by sandwiching and fixing the resin-framed glass plate 100 between the first cushioning material 12 and the second cushioning material 13, it is possible to suppress the positional shift of the resin-framed glass plate 100 during transportation.

In particular, when the resin-framed glass plate 100 does not have a fixing device 103, it is preferable to clamp the resin-framed glass plate 100 using the first cushioning material 12 and the second cushioning material 13 so that the thickness of the first cushioning material 12 and the second cushioning material 13 after deformation is approximately 80% to 99% of the original thickness. This effectively prevents the resin-framed glass plate 100 from shifting out of position during transportation.

Next, the operation of storing a resin-framed glass plate 100 in the glass plate storage device 1 according to the present embodiment will be described. When storing a resin-framed glass plate 100 in the glass plate storage device 1 according to the present embodiment, the resin-framed glass plate 100 is first placed on the first cushioning material 12 of the horizontal shelf 11a. Then, the next shelf 11b is flipped up and brought to a horizontal state, so that the resin-framed glass plate 100 is stored between the shelves 11. By repeating this operation, multiple resin-framed glass plates 100 can be stored in the spaces between multiple shelves 11 that are spaced apart from each other in the vertical direction. Below, the operation of storing a resin-framed glass plate 100 in the glass plate storage device 1 according to the present embodiment will be described in detail with reference to Figures 9 to 12.

First, as shown in the cross-sectional view of FIG. 9 and the top view of FIG. 10, a resin-framed glass plate 100 is placed on the first cushioning material 12 of the horizontal shelf 11a. At this time, the resin-framed glass plate 100 is placed on the first cushioning material 12 so that the fixing device 103 of the resin-framed glass plate 100 abuts against the first cushioning material 12 (see FIG. 9). The example shown in FIG. 9 and FIG. 10 shows an example in which four resin-framed glass plates 100 are stored on one shelf 11a. Note that the number of resin-framed glass plates 100 stored on one shelf 11a can be changed as appropriate depending on the shape and size of the resin-framed glass plates 100.

Next, as shown in the cross-sectional view of FIG. 11, the shelf 11b one level above the shelf 11a on which the resin-framed glass plate 100 is placed (next level) is brought from a raised state to a horizontal state. By bringing the next level shelf 11b into a horizontal state in this way, the second cushioning material 13 is abutted against the upper surface of the resin-framed glass plate 100, as shown in FIG. 12. This operation allows the resin-framed glass plate 100 to be sandwiched and fixed between the first cushioning material 12 and the second cushioning material 13. By repeating the above-mentioned operation, multiple resin-framed glass plates 100 can be stored in the space between multiple shelves 11 arranged at a distance from each other in the vertical direction.

As explained in the background art, resin-framed glass sheets have a resin frame formed around the glass sheet. For this reason, if the resin frames come into contact with each other during transport of the resin-framed glass sheets and force is applied to the resin frame, the resin frame may be deformed. If the resin frame is deformed in this way, the resin-framed glass sheets become defective products. To solve this problem, in the past, the glass sheets were individually wrapped in polyethylene sheets before being shipped from the factory, and then stored in a storage means together with cushioning material. However, if the resin-framed glass sheets were individually wrapped and then stored in a storage means, there was a problem that the storage work became cumbersome.

In contrast, in the glass plate storage device 1 according to the present embodiment, multiple shelves 11 are arranged so as to be spaced apart from one another in the vertical direction, and each shelf 11 is configured to be rotatable about a pivot axis between a horizontal state and a raised state. Then, between each shelf 11 arranged so as to be spaced apart from one another, the resin-framed glass plate 100 is arranged between the first cushioning material 12 and the second cushioning material 13 to store the resin-framed glass plate 100. This simplifies the process of storing the resin-framed glass plate 100.

In particular, in the glass plate storage device 1 according to this embodiment, a resin-framed glass plate 100 is placed on the first cushioning material 12 of the horizontal shelf plate 11a, and then the next shelf plate 11b is flipped up and brought to a horizontal state, thereby storing the resin-framed glass plate 100 between the shelves 11. By repeating this operation, multiple resin-framed glass plates 100 are stored in the spaces between multiple shelves 11 that are spaced apart from each other in the vertical direction. This simplifies the process of storing the resin-framed glass plates 100.

The present invention has been described above in accordance with the above embodiment, but the present invention is not limited to the configuration of the above embodiment, and of course includes various modifications, alterations, and combinations that a person skilled in the art could make within the scope of the invention of the claims of this patent application.
