Description

[Detailed explanation of the idea] The present invention relates to a lid for a school bag.

Since the left and right edges and the lower edge of the lid of the school bag protrude outward from the outer surfaces of the left and right side walls and bottom wall of the school bag body, the left and right edges and the lower edge of the cover plate do not touch other parts. There is a lot of damage in comparison, especially at the lower end.

Therefore, conventionally, by interposing a horizontally long rectangular piece of sponge between the front plate and the back plate that make up the cover plate and at the lower end thereof, a rectangular lower protuberance is created at the lower end of the cover plate. By forming a band-shaped piece of sponge between the front plate and the back plate and interposing it on both the left and right edges,
Left and right ridges are formed on the upper side of the lid plate, excluding the lower end portions of both left and right edges thereof, and are integrally continuous with the lower ridge, and these ridges form the bottom edge of the lid plate and the upper part thereof. It is known that the left and right edges are reinforced and the external impact is alleviated.

The present invention proposes a lid for a school bag that can reinforce the left and right edges more strongly than the conventional one and also has a good decorative effect.

In other words, the lid of the school bag of the present invention has a core material such as a piece of sponge polymerized on the outer surface of both the left and right edges of the lid plate, and this core material is covered with a soft plastic covering tape whose back surface is a retroreflective surface. At the same time, at the lower edge of the lid plate, a piece of sponge is interposed inside to form a lower raised part, and these left and right raised parts and lower raised part are covered with The left and right reinforcing pieces and the lower reinforcing piece are superimposed on the back side of the corresponding cover plate, and the end faces of both the left and right edges of the cover plate, the end face of the above-mentioned covering tape laminated thereon, and each of the above-mentioned reinforcing pieces are Cover the end face and the end face of the lower edge of the lid plate with a piece of edging tape, and further,
The lid plate, covering tape, reinforcing pieces, and edging tape are sewn together.

The present invention will be described in detail below with reference to two embodiments: a first embodiment shown in FIGS. 1 to 3 and a second embodiment shown in FIG.

First, a first embodiment will be explained. FIG. 1 shows a state in which a lid A according to the present invention is attached to a school bag body B, and the attachment is performed by a conventionally known method.

The lid A includes band-shaped left and right raised parts 2, 2 extending over the entire length of the flexible lid plate 1 on both left and right edges of the outer surface thereof, and left and right raised parts 2, 2 at the lower end of the outer surface. A horizontally long rectangular lower raised part 3 is formed between the parts 2, 2.

As is clear from FIGS. 2 and 3, the lid plate 1 is made by laminating and bonding a top plate 4 and a back plate 5 made of natural leather or artificial leather.

There are band-shaped reinforcing pieces 6, 6 on the left and right edges of the back plate 5.
However, a horizontally long rectangular reinforcing piece 7 is attached to the lower end of each.

These reinforcing pieces 6, 6, and 7 are also made of natural leather or artificial leather, and the lower reinforcing piece 7 has a length spanning both the left and right ends of the back plate 5, while the left and right reinforcing pieces 6, 6 are on the back side. The lower part of the plate 5 is interrupted halfway, and the interrupted lower end is covered with a lower reinforcing piece 7,
As a result, the entire length of the left and right edges of the cover plate 1 and the lower end forming the lower raised portion 3 are reinforced from the back side.

The lower raised portion 3 is formed by interposing a horizontally long rectangular sponge piece 8 between the front plate 4 and the back plate 5.

The front plate 4, the back plate 5, and the lower reinforcing piece 7 are sewn together along the upper and lower edges of the sponge piece 8 with threads 9 and 10.

The left and right raised parts 2, 2 are formed by covering a band-shaped sponge piece 11 serving as a core material on the top plate 4 with a soft plastic covering tape 12, and sewing the long edges of both sides of the covering tape 12 to the cover plate 1. It is formed by This sewing is done for each covering tape 1
The inner long edges of both covering tapes 12, 12 are sewn with the same thread 10 as the thread 10 used to sew the lower reinforcing plate 7 together. This is done by twisting and sewing, and this sewing also allows the front plate 4 and the back plate 5 to be joined together.
The reinforcing piece 6 on the left side and the front plate 4, the back plate 5, and the reinforcing piece 6 on the right side are sewn together.

The covering tape 12 is colored in a desired color and has translucency, but its back surface is a retroreflective surface with countless fine prismatic convexities and concave portions, which prevents incident light from entering the tape. It reflects light well, and especially in dark places, the colored color becomes the reflected color and appears bright and shining.

The left and right edges of the lid 1 to which the covering tapes 12, 12 and reinforcing pieces 6, 6 are sewn together in this way and the lower edge of the lid plate 1 to which the reinforcing pieces 7 are sewn are connected together with a single edging tape 14. covered by.

This edging tape 14 is also made of natural leather or artificial leather, and its long edge on one side is overlapped with the left and right covering tapes 12, 12 and the lower edge of the top plate 4, and attached to the lid plate 1 by threads 15. The long edge of the other side, which is folded back to the back side, is stuck to the left and right reinforcing pieces 6, 6 and the lower reinforcing piece 7, and is further sewn with the thread 10.

At the center of the back side of the lower end of the lid plate 1, a tongue piece 18 is fixed to which two pieces 16 and 17 of natural leather or artificial leather are attached. This fastening consists of a top plate 4, a sponge piece 8, a back plate 5, a reinforcing piece 7, and a tongue piece 1.
8 are connected to each other with left and right studs 19, 19, and the portion between these studs 19, 19 is sutured with thread 20.

A base 21 is fixed to the free end of the tongue piece 18, which can be engaged with a known lock attached to the lower surface of the school bag body B.

Thus, the lid A has band-shaped left and right raised parts 2 along the entire length of the left and right edges of the outer surface of the lid plate 1, and a horizontally long rectangular lower raised part 3 is formed at the lower end. Therefore, these raised parts can reinforce the entire length and lower end of the left and right edges of the cover plate 1, and have a good decorative effect.Moreover, these raised parts have sponge pieces 11 or 8 embedded in them, making them flexible. It has a cushioning effect that can cushion the impact.

In particular, the left and right protrusions 2, 2 are formed by the sponge piece 1.
In addition to tapes 1 and 11, covering tapes 12 and 12 made of soft plastic also reinforce the cover plate 1 from the front side and have a cushioning effect, and these raised portions extend to both left and right sides of the lower raised portion 3. and reaches the left and right corners of the lower end of the cover plate 1.
The entire length of the left and right edge portions including these left and right corner portions can be further reinforced, and the impact can be alleviated over the entire length.

In addition, the entire length of the outer surface of the left and right protrusions 2, 2 is a retroreflective surface that reflects light well by the covering tape 12, and especially in a dark place, the color of the covering tape 12 becomes the reflected color. It looks bright and shining, and because it is raised, it can be seen from the left and right sides of the cover plate 1, making the decorative effect even better. It is possible to alert drivers of approaching vehicles and prevent traffic accidents.

Next, the lid A' of the second embodiment shown in FIG. The only difference from the first embodiment is that it has been improved, and the rest is the same.

As mentioned above, the lid of the school bag according to the present invention consists of a core material that overlaps the outer surface of the left and right edges of the lid plate, a covering tape that covers this core material to form a raised part, and left and right reinforcements on the back side of the lid plate. a sponge piece reinforced by a piece and an edging tape, and in which the lower edge of the lid plate is interposed to form a lower raised part;
It is reinforced with the lower reinforcing piece on the back of the lid plate and the edging tape, and the left, right and lower edges of the lid plate, which are particularly prone to damage in school bag lids, can be protected robustly and stylishly. Therefore, it can be used for a long period of time.

In addition, the above-mentioned covering tape, each reinforcing piece, and the edging tape can be protected by a simple method of cutting them into the required shape and size and sewing them onto the lid plate. Manufacturing is simple because there is no need to use a mold to form a fixed fitting structure.

Furthermore, the entire length of the outer surface of the left and right raised parts is a retroreflective surface that reflects light well due to the covering tape, so especially in a dark place, the color of the covering tape becomes the reflected color. It appears to shine brightly, and due to its raised ridges, it can be seen from the left and right sides of the lid plate.
The decorative effect is even better, and when carrying a school bag,
It is possible to alert drivers of vehicles approaching from the rear, left and right sides, and traffic accidents can be prevented.
