Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a school bag. More specifically, the present invention relates to a school bag in which a waist belt is detachably attached to a school bag made of leather or synthetic leather.

[0002]

2. Description of the Related Art In general, the size of a school bag is manufactured based on a figure of a child of a junior high school age. For this reason, first-grade elementary school students with a small physique or higher-grade children who are close to the adult body shape adjust the length of the carrying belt to fit the body shape.

[0003]

However, in the case of a first grader, the school bag is generally larger than the child's body, so the school bag does not match any of the child's shoulder width, waist width and height. Also, the position of the carrying belt is not on the body. Naturally, the school bag is carried in an extremely unstable state without adhering to the back. If you shorten the length of the carrying belt to obtain a close contact,
The body is unnaturally squeezed and cramped, and carrying on one's back is very uncomfortable. Therefore, the backpack belt is used with an appropriate length without feeling cramped, and the poor adhesion of the backpack to the back caused by this is solved by supporting the backpack by hand or pulling it forward. . However, this method has a problem in that walking is dangerous because both hands are blocked.

In the sixth grade, the length of the backpack belt is lengthened to prevent the backpack from becoming cramped. However, since the attachment position of the backpack of a small school bag to a large body is basically out of the body, the schoolbag body is warped, or the schoolbag body is poorly adhered to the back, resulting in an unstable backpack.

An object of the present invention is to provide a school bag which assists an unstable carrying state of a school bag and which is comfortable and safe.

[0006]

According to a first aspect of the present invention, there is provided a school bag provided with a belt connector rotatably in the left-right direction at a side edge of a backrest, and a separate waist belt detachably attached to the belt connector. It is characterized by being provided. According to a second aspect of the invention, the belt connecting member has a rigid belt connecting ring on the distal end side, and the belt connecting ring is rotatable left and right with respect to the backrest portion and is undulating. And According to a third aspect of the invention, there is provided a backpack, wherein a recess for accommodating the belt connector is provided on a surface of the backrest.

[0007]

In the school bag according to the first aspect, a belt connecting member of the waist belt is provided on the side edge of the backrest of the school bag so as to be rotatable in the left-right direction, and a separate waist belt is attached to the belt connecting device. It is removable. Therefore, if the waist belt is unnecessary, the waist belt can be removed. When the waist belt is not worn, the belt connector can be rotated inward to keep in contact with the backrest. In this state, since the belt connecting member is interposed between the back and the school bag, the appearance is good because it is not seen. If it is necessary to attach the waist belt, the belt connector may be turned outward to stand up from the backrest, and the waist belt may be worn thereon. That is, when the waist belt is not worn, the belt connector can be in an appearance and appearance that is not seen, and when the waist belt is worn, the waist belt can be easily worn. Can be connected.

According to a second aspect of the invention, there is provided a school bag having a rigid belt connecting ring on the tip end side of the belt connecting member, and the belt connecting ring is rotatable left and right with respect to a backrest portion and is undulating. I have. Therefore, when the waist belt is unnecessary, if the belt connecting ring is turned down inward or outward and is brought into contact with the backrest, the belt connecting ring does not hit the back, so that it is extremely safe. Also, if a waist belt is required, the belt connector can stand up to a position close to your waist, so the end of the waist belt connected to the belt connector can be easily angled along the waist, It prevents an excessive tightening force from being applied to the waist. In addition, compression that gives an uncomfortable feeling to the waist is prevented. Therefore,
The waist belt gently contacts the waist of the child, ensures that the lower part of the school bag comes into contact with the waist, and secures the school bag to the waist.

According to the third aspect of the present invention, since the concave portion for accommodating the belt connector of the waist belt is provided on the surface of the side edge of the backrest portion of the school bag, the belt connector can be either inward or outward. Even in the inverted state, it does not protrude from the surface of the backrest. That is, the belt connector can be stored in the recess in a buried state. Therefore, since there is no excess on the surface of the backrest portion, the adhesion between the school bag and the waist is extremely good, and there is almost no discomfort to the waist, so that a comfortable backing state can be obtained.

When a waist belt is required, the belt connecting tool in the concave portion can be easily connected to the waist belt by standing up with a finger or the like. In the use state of the waist belt, since the base end of the belt connector is below the surface of the backrest, the school bag can be reliably drawn to the waist. However, since the presence of the concave portion does not give any uncomfortable feeling to the waist, a comfortable back state can be obtained.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a back bag according to an embodiment of the present invention. FIG. 1 is a perspective view showing one embodiment of the present invention, FIG. 2 is an exploded perspective view of a backrest of FIG. 1, FIG.
4 is an enlarged sectional view taken along line XX of FIG. 3, and FIG. 5 is a sectional view taken along line YY of FIG.
6a to 6c are explanatory views showing an operation range of the connecting tool, and FIGS. 7a to 7c are explanatory views of a use state.

The backrest 1 of the school bag A shown in FIGS. 1 and 2 has a high mountain cushion portion (hereinafter, referred to as a high cushion portion) 2 from both sides to the lower portion of the surface thereof.
In addition, a low mountain cushion portion (hereinafter, referred to as a center)
3).

As shown in FIG. 3, recesses 5 and 5 for accommodating the belt couplings 4 and 4 are provided below the side edges of the high cushion portions 2 on both sides. The belt connecting member 4 includes a belt connecting ring 7 on the distal end side, the connecting ring 7 wound around the belt connecting ring 7, and a recess 5.
And a fixing member 6 on the proximal end side which is fixed to the base member. The belt connecting ring 7 is made of a synthetic resin, has a flat front and back surface, and is a substantially triangular thin body having a thickness of about 2 mm. A slit-shaped through hole 8 is formed on the base end side, and a connection hole 11 for engaging with a hook ring 10 of a waist belt 9 is formed on the distal end side.
Are drilled. The lateral length of the belt connecting ring 7 is 2
About cm is desirable. The fixing member 6 is wound around the through hole 8, and the fixing member 6 is a band having a width substantially equal to the height of the slit-shaped through hole 8, and the longitudinal direction of the band is flexibly folded. It bends, but has little buckling or flexibility in the longitudinal direction. The fixing member 6 is formed in the recess 5 by a stud 12 penetrating from the front surface of the fixing member 6 to the back surface of the backrest 1 near the base end of the belt connecting member so that the belt connecting ring 7 can rotate and undulate freely. It is fixed.

As shown in FIGS. 4 and 5, the depth D of the recess 5 is such that the belt connecting ring 7 is buried in the recess 6 irrespective of inward or outward in the direction indicated by the arrow. It is set to the depth that can be. The bottom surface of the recess 5 has no particular elasticity and is formed as a substantially flat surface. Therefore,
The surface of the fixing member 6 can be stuck to the fixing member 6 so that the surfaces of the fixing member 6 can be in contact with each other, so that the fixing member 6 is stably stuck, and the connecting ring 7 can be surely rotated and erected. The slope 5a extending from the high cushion portion 3 to the bottom surface of the concave portion 5 is rich in elasticity because the high cushion portion 3 exists. The shape of the bottom surface of the concave portion 5 is substantially the same as the shape of the outer periphery of the belt connector 4, but the longitudinal dimension W in the lateral direction is slightly shorter than that of the belt connector 4. Therefore, since the end of the belt connecting ring 7 can be pressed against the slope 5a, when the belt connecting ring 7 is in an inwardly folded state, it is held in a stored state, and the connecting ring 7 is prevented from turning outward. When the high cushion portion 3 is not provided, the concave portion 5 is provided in the base material of the backrest 1 itself.

As shown in FIG. 1, the waist belt 9 is connected to left and right belt pieces 9a and 9b, a joint (buckle) 13 for detachably connecting the ends thereof, and left and right ends. It comprises a hook ring 10 and length adjusting members 14, 14 for adjusting the lengths of the belt pieces 9a, 9b. Hanging ring 1
Numeral 0 denotes a so-called eggplant ring which is rotatable around its own axis, and a conventionally known one may be appropriately used. As the belt piece, cloth, leather, synthetic leather, or the like is used. The joint 13 is not essential, but is preferably provided because it can be attached and detached at the center of the body. Reference numeral 14 denotes a perforation for forming the high cushion portion 2 and the low cushion portion 3 separately, 15 denotes a perforation for forming the concave portion 5, 16, 17
Is a left and right backing belt, and 18 is a backing belt attachment.

Next, the method of use will be described with reference to FIGS. 6A to 6C and FIGS. 7A to 7C. In the case of middle-aged or standard-sized children in whom the waist belt 9 is not particularly necessary, the belt connecting ring 7 is completely folded inward as shown in FIG. 6A. Since the belt connecting ring 7 in this state is completely housed in the concave portion 5, the high cushion portion 3 is provided.
Never go out on the surface. Therefore, as shown in FIG. 7A, in the state of carrying the school bag on the back, there is no discomfort such as contact of foreign matter on the back and waist, and only the high cushion portion 3 contacts the waist, so that the feeling of carrying on the back is good. Even if the belt connecting ring 7 jumps out of the concave portion 5 due to some impact, the surface of the belt connecting ring 7 is flat, so that there is no uncomfortable feeling even when it comes into contact with the body. In particular, as shown in FIG. 4, if the end of the belt connecting ring 7 is pressed against the side surface 5a, the belt connecting ring 7 can be fixed in the concave portion 5, so that the protrusion from the concave portion 5 is prevented as much as possible. Is done. Further, even when the connecting ring 7 of the belt mounting member 5 is turned down outward, it does not go out on the surface of the concave portion 5 and the fixing member can hold the down state or the down angle. ,
The carrying state of the school bag is good.

Next, when a lower grader or a slender child who wears a waist belt whose waist width is smaller than the width of the school bag wears a waist belt, for example, as shown in FIG. The waist belt 9 is hooked onto the waist belt 9 for use when standing up to an appropriate angle. As is evident, the ends of the waist belt 9 can be raised at the most optimal position and angle. Therefore, as shown in FIG. 7B, the belt can be fastened to the waist B without applying excessive force to the waist B. Even when the school bag swings, the connecting ring 7 and both ends of the waist belt are freely rotatable. Therefore, the waist belt in the tightened state is prevented from locally applying pressure to the waist, and is always gently tightened. The school bag can be fixed to the waist.

Thus, the state of carrying the school bag can be stabilized, and tight tightening by the carrying belt can be eliminated. In particular, in this embodiment, the high cushion portion 2 hits the back and softly transmits the weight of the school bag to the back, and the waist belt 9 firmly tightens the school bag on the back. .

In the case where a higher grader or a child with a good physique, whose waist is wider than the width of the school bag, wears a waist belt,
For example, as shown in FIG. 6C, the belt connecting ring 7 is turned down to an appropriate angle in accordance with the width of the waist B, and the hooking ring 10 is used by hooking it. Although the waist width of the child is wider than the width of the lower end of the school bag, as shown in FIG.
Since both ends are located behind the waist B, the body is tightly wrapped from behind the waist B to the abdomen via both sides.
Therefore, since the waist belt 9 can draw the lower end of the school bag toward the waist and press it against the waist, it is extremely effective to securely fix the school bag to the waist and to put the school bag in a stable backing state.
