Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention aims to reduce the weight and
The present invention relates to a school bag in which the tip of the cover and the outer surface of the bottom of the school bag body can be easily engaged and disengaged.

[0002]

2. Description of the Related Art Conventionally, for example, an engaging structure at the tip of a cover lid in a school bag is shown in FIG. That is, the bottom outer surface 10 of the leather school bag body 100
1, a metallic receiving member 102 is attached to the receiving member 102, the base ends of the auxiliary bands 103 and 103 are attached to both sides of the receiving member 102, and a recess 104 is provided in the center in the vertical direction.
A magnet is provided inside the bottom of the recess 104 and a support shaft 105 is erected on the outside, and the support shaft 10 is provided at the upper end of the support shaft 105.
5, a locking piece 106 that is perpendicular to 5 is rotatably attached. On the other hand, a locking member 108 is attached to the tip of the cover lid 107. The locking member 108 is made of a metal plate,
It is configured by vertically extending oblong holes 109, 109. One of the oblong holes 109 is fitted to the engaging piece 106, and the engaging member 108 is magnetically attached to the magnet inside the recess 104, The locking piece 105 is rotated by about 90 degrees to be engaged, and the long hole 1
It is arranged to prevent the locking piece 106 from coming out from the 09.

[0003]

However, in such a structure, the receiving member 102 and the locking member 10 are provided.
Since both 8 are made of metal, they have a considerable influence on the overall weight of the school bag body 100, and the promotion of weight reduction of this school bag is hindered. In addition, the receiving member 102 has a complicated structure such as the pivoting of the locking piece 106, and since the magnet is internally provided, its manufacturing and mounting are troublesome and the manufacturing cost is high.

Further, since the long hole 109 is fitted in the locking piece 106 and the locking piece 106 is further rotated to be engaged, the operation is troublesome, and the schoolchild is rough and hurry. However, the supporting shaft 105 of the locking piece 106 is easily bent or broken, and is easily broken, and the durability is poor. Therefore, an object of the present invention is to provide a school bag that solves such problems.

[0005]

In order to achieve such an object, the present invention extends a cover lid for covering the upper end opening and the front surface of the school bag body from the upper edge of the back plate, and attaches the tip of the cover lid. In a school bag that is detachably engaged with the outer surface of the bottom of the school bag body, a plate-like locking member made of rubber or plastic material containing magnetic powder is fixed to the tip of the cover, while the school bag is used. A flat plate-shaped receiving member, which is made of rubber or plastic material containing magnetic powder and has a relatively large magnetically adhering surface to which the locking member abuts and is magnetically fixed, is fixed to the outer surface of the bottom of the main body. And configure.

[0006]

Since the locking member and the receiving member are both made of rubber or plastic material, the weight of the entire school bag can be reduced, and the structure is simple, so that it can be easily manufactured and mounted. Further, since the locking member is magnetically attached only by coming into contact with the receiving member, it can be engaged very easily by one-touch operation.
Moreover, since it is only magnetically attached, it has a simple structure and is not easily broken.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a school bag according to the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a school bag main body in which a main storage portion A and a sub storage portion B are juxtaposed side by side. An arc-shaped continuous piece 5 is integrally provided on the edge of the cover lid 4 that extends. Furthermore,
A projecting piece 6 is provided at the center of the continuous piece 5, and a locking member 7 is fixed to the inner surface thereof. The locking member 7 is made of a rubber material containing magnetic powder and has a plate shape, and the inner surface thereof is, for example, an S pole. Reference numeral 6a is a knob piece provided on the outer side surface of the projecting piece 6.

On the other hand, a flat plate-shaped receiving member 9 is fixed to the outer surface 8 of the bottom of the school bag body 1. The receiving member 9
Like the locking member 7, is made of a rubber material containing magnetic powder, and the outer surface thereof is, for example, an N pole. A magnetically adhering surface 9a having a relatively large area is formed in the center.

Further, the left and right sides of the receiving member 9 are locking pins 1 for integrally fixing the bottom portion of the school bag body 1 and the receiving member 9.
0 and 10 are skewed, and locking members 11 and 11 are rotatably attached to the respective stop pins 10 and 10. 12,
Reference numeral 12 is an auxiliary band provided with buckles 13 and 13 at its tip, and the base end thereof is fixed to each of the locking members 11 and 11. 14 and 14 are shoulder straps connected to the buckles 13 and 13.

The school bag of the present invention has the above structure,
As shown in FIGS. 2 and 3, the upper end opening 3 of the school bag body 1
The locking member 7 is magnetically attached and can be firmly engaged only by covering the a and the front surface 3b with the cover 4 and bringing the locking member 7 into contact with the magnetic surface 9a of the receiving member 9. In this case, since the magnetically attached surface 9a has a relatively large area, the locking member 7 may be slightly laterally displaced, so that the engagement can be easily performed. Further, when removing the locking member 7, it suffices to pull the knob 6a. The magnetic powder is made of a ferromagnetic material such as Fe, Co, or Ni, which has a strong magnetic force.
It is desirable to increase the mutual contact area. Also, N
The pole and the S pole may be reversed.

In the structure shown in FIG. 4, the base end of the bar member 15 having a length longer than the width of the locking member 7 is rotatably supported on the upper surface of the receiving member 9 and the bar member 15 is rotatably supported. The tip is releasably engaged with a locking tool 16 also provided on the upper surface of the receiving member 9. Further, a knob piece 6a is also provided on the upper surface of the projecting piece 6. According to this, even if the cover lid 4 is pulled with a strong force and the locking member 7 is about to be disengaged from the magnetic surface 9a, the tab 6a is caught by the bar member 15 and is prevented from being pulled out. The engagement of the locking member 7 with the stop member 9 can be made even stronger.

In this embodiment, the locking member 7
Although the receiving member 9 and the receiving member 9 are made of a rubber material, they may be made of a plastic material containing magnetic powder. In this case, the bottom surface of the school bag body 1 can be made more robust.

[0013]

As described above, according to the school bag of the present invention, both the receiving member to be mounted on the outer surface of the bottom of the school bag body and the locking member to be mounted to the tip of the cover are both rubber or plastic containing magnetic powder. Since it is made of a material, the weight of the main body of the school bag can be reduced, and since the receiving member is in the form of a flat plate, it can be easily formed and the mounting operation can be facilitated, and the manufacturing cost can be reduced. Further, both the locking member and the receiving member can be easily engaged by a literal one-touch operation, are easy to use, and are hard to disengage, and the original purpose can be sufficiently achieved. Further, both the locking member and the receiving member have the advantages that they have a simple structure and are hard to break and have excellent durability.
