Abstract
Description
Technical Field
[0001] The present invention relates to a lid cover for a schoolbag that protects children from traffic accidents and the like. More specifically, it relates to a lid cover for a schoolbag that can change the mounting surface according to the usage.
Background Art
[0002] Conventionally, as a cover for a schoolbag, a cover for a schoolbag with its outer peripheral edge covered with a reflective tape has been proposed (Patent Document 1). When light from an automobile hits the reflective tape covering the peripheral edge of the schoolbag cover at night or the like, the cover reflects the light to notify the presence of children carrying the schoolbag and protect the children from traffic accidents and the like.
[0003] In addition, safety visibility devices that are attached to and used on covers for backpacks such as schoolbags have been proposed (Patent Document 2). The safety visibility device can change the attachment position of the light reflector to a position where it is most easily hit by the light of an automobile headlight, make the area of the cover that closes over the light reflector narrow, remove the light reflector from the cover when not needed, and replace it with a new one when the light reflector is damaged.

Summary of the Invention
Problems to be Solved by the Invention
[0006] The present invention relates to a lid cover for a schoolbag that protects children from traffic accidents and the like. More specifically, it relates to a lid cover for a schoolbag that can change the mounting surface according to the usage. Even more specifically, it relates to a lid cover for a schoolbag that can protect children carrying the schoolbag from traffic accidents and the like by mounting the outer surface of the lid of the schoolbag with a waterproof or decorative display surface during daily use and a display surface with light reflectivity on the outer surface of the lid of the schoolbag at night or in other cases. At the same time, it prevents the lid of the schoolbag from being soiled or damaged.
Means for Solving the Problems
[0007] The lid cover of the schoolbag of the present invention for solving the above problems is formed by overlapping a fabric having waterproofness or decoration or the like and a fabric having light reflectivity to form a main body portion having substantially the same size as the lid of the schoolbag, and a strip-shaped sheet in which the tip of the lid of the schoolbag is inserted into one end portion of one side surface of the main body portion and an insertion hole for a key fitting provided at the tip of the lid is formed is fixed, and a locking and fixing portion for the upper part of the schoolbag is provided at the other end portion of one side surface of the main body portion, and a stretchable band crossing the main body portion is provided between the locking and fixing portion and the strip-shaped sheet (Claim 1). Note that the "decoration or the like" refers to colors, patterns, designs, etc. according to preferences.
[0008] In the above configuration, one side surface of the main body portion is a fabric surface having waterproofness or decoration or the like, and the other side surface is a fabric surface having light reflectivity, and all of the strip-shaped sheet, the stretchable band, etc. including the main body portion have flexibility.
[0009] Therefore, when the portion of the strip-shaped sheet provided on one side surface of the main body portion is turned over (reversible), the strip-shaped sheet is transferred to the other side surface (back surface). At the same time, the stretchable band can also be stretched and easily transferred to the other side surface (back surface).
[0010] The case of attaching the lid cover having the above configuration to the lid of the schoolbag will be described.
[0011] First, when the strip sheet and the elastic band are located on the raw floor having waterproofness or makeup, etc., the strip sheet and the elastic band surface are arranged facing the outer surface of the lid of the backpack. Next, the tip of the lid of the backpack is passed between the main body and the elastic band from the side of the locking and fixing portion of the main body. Further, the tip of the lid of the backpack is inserted between the main body and the strip sheet, and the key fitting is taken out from the insertion hole. Then, it is performed by fixing the locking and fixing portion provided at the other end of the main body to a hanging fitting or the like provided at the upper part of the back of the backpack.
[0012] In the attached state of the lid cover, the strip sheet and the elastic band are hidden inside the lid of the backpack, and the surface having light reflectivity becomes the outer surface of the lid of the backpack, and it is worn by the strip sheet, the elastic band and the locking and fixing portion, and it becomes effective for use at night or the like.
[0013] Next, the case where the surface having waterproofness or makeup of the lid cover of the present invention is attached as the outer surface of the lid of the backpack will be described.
[0014] First, when the strip sheet portion provided on one side surface of the main body is turned over (reversible), the strip sheet portion is transferred to the other side surface (the surface having light reflectivity). At the same time, the elastic band is expanded and contracted and also transferred to the other side surface (the surface having light reflectivity). The subsequent attachment to the lid of the backpack is the same as described above.
[0015] That is, the surface having light reflectivity to which the strip sheet and the elastic band are transferred is arranged facing the outer surface of the lid of the backpack. Next, the tip of the lid of the backpack is passed between the main body and the elastic band from the side of the locking and fixing portion of the main body. Further, the tip of the lid of the backpack is inserted between the main body and the strip sheet, and the key fitting is taken out from the insertion hole to the outside. Then, it is performed by locking the locking and fixing portion provided at the other end of the main body to a hanging fitting or the like provided at the upper part of the back of the backpack.
[0016] In the attached state of this lid cover, the strip-shaped sheet and the elastic band are hidden inside the lid of the backpack, and the surface with waterproof or decorative properties becomes the outer surface of the lid of the backpack. It is attached by the strip-shaped sheet, the elastic band, and the locking and fixing parts to be in the daily use state.
Advantages of the Invention
[0017] According to the present invention, during the day, the backpack is worn with the raw surface having waterproof or decorative properties on the outer surface of the lid of the backpack, and at night or the like, the backpack is worn with the raw surface having light reflectivity on the outer surface of the lid of the backpack, so that children carrying the backpack can be protected from traffic accidents and the like.

[0019] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0020] First, the backpack will be described. As shown in FIG. 5, the backpack 20 includes a storage part 21 for textbooks, notebooks, etc., a lid 22, a carrying belt 23, etc. In the figure, 24 is a hanging fitting for hanging the backpack 20, and 25 is a key fitting provided at the tip 22a of the lid 22. The key fitting 25 is configured to fit into a lock part (not shown) provided on the lower surface of the storage part 21 of the backpack 20.
[0021] FIG. 1 is a plan view of the lid cover 1 of the present invention, and FIG. 2 is a rear view of the lid cover 1. The main body 2 forming the lid cover 1 of the present invention is formed by overlapping a fabric having waterproofness or makeup, etc. and a fabric having light reflectivity to substantially the same size as the lid 22 of the backpack 20.
[0022] For example, the front surface is made of a waterproof or decorative fabric surface A (see FIG. 1) made of polyester or the like, and the back surface is preferably formed on a fabric surface B (see FIG. 2) having light reflectivity such as retroreflectivity. And the whole is in a sheet shape.
[0023] Furthermore, on one side surface of the main body 2, for example, in the state of FIG. 1, a strip-shaped sheet 4 that receives the tip 22a of the lid 22 of the backpack 20 at one end of the fabric surface A and forms an insertion hole 3 for the key fitting 25 provided at the tip 22a of the lid 22 is fixed.
[0024] Furthermore, an engagement fixing portion 5 that engages with a hanging fitting 24 for suspending the backpack 20 provided on the backpack 20 is formed at the other end of the fabric surface A. The locking and fixing portion 5 is preferably made of an elastic material. Further, an elastic band 6 such as a rubber string that crosses the main body 2 is provided at an appropriate position between the locking and fixing portion 5 and the strip-shaped sheet 4 to constitute the lid cover 1 of the backpack of the present invention.
[0025] A case where the lid cover 1 of the present invention having the above configuration is attached to the lid 22 of the backpack 20 will be described with reference to the drawings.

Further, the tip 22a of the lid 22 of the backpack 20 is inserted between the main body 2 and the strip sheet 4, and the key fitting 25 is taken out from the insertion hole 3 thereof. Then, it is performed by fixing the locking and fixing portion 5 provided at the other end of the main body 2 to the hanging fitting 24 provided at the upper part of the back of the backpack 20, etc.
[0027] In the attached state of this lid cover 1, the strip sheet 4 and the elastic band 6 are in a state of being hidden inside the lid 22 of the backpack 20, and the raw ground B having light reflectivity becomes the outer surface of the lid 22 of the backpack 20 and is attached to the lid 22 by the strip sheet 4, the elastic band 6 and the locking and fixing portion 5, so that use at night or the like becomes effective.
[0028] Next, the case where the lid cover 1 of the present invention having the above configuration is attached with the raw ground A having waterproof property or decoration, etc. as the outer surface of the lid 22 of the backpack 20 will be described.
[0029] In this case, it is necessary to shift the strip sheet 4 and the elastic band 6 on the raw ground A having the waterproof property or decoration, etc. to the raw ground B having light reflectivity as shown in FIG. 3.
[0030] For that purpose, the strip sheet 4 portion of the raw ground A having the waterproof property or decoration, etc. is turned over (reversible), so that the strip sheet 4 is shifted to the raw ground B having light reflectivity. At the same time, the elastic band 6 can also be expanded and contracted and shifted to the raw ground B having light reflectivity.
[0031] The subsequent attachment of the lid 22 to the backpack 20 is the same as described above. That is, the light-reflective raw ground B having the strip-shaped sheet 4 and the elastic band 6 is arranged facing the outer surface of the lid 22 of the backpack 20, and the tip 22a of the lid 22 of the backpack 20 is passed through between the main body 2 and the elastic band 6 from the side of the locking and fixing portion 5 of the main body 2. Further, the tip 22a of the lid 22 of the backpack 20 is inserted between the main body 2 and the strip-shaped sheet 4, and the key fitting 25 is taken out from the insertion hole 3 to the outside.
[0032] And it is performed by fixing the locking and fixing portion 5 provided at the other end of the main body 2 to the hanging fitting 24 provided at the upper part of the back of the backpack 20.
[0033] In the attached state of this lid cover 1, the strip-shaped sheet 4 and the elastic band 6 are hidden inside the lid 22 of the backpack 20, and the waterproof or decorative raw ground A becomes the outer surface of the lid 22 of the backpack 20 and is attached to the lid 22 of the backpack 20 by the strip-shaped sheet 4, the elastic band and the locking and fixing portion 5 to be in the daily use state.
