Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoulder belt upper end fitting for a backpack such as a school bag or rucksack.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 6 and 7, a mounting ring 3 has been used for a shoulder belt upper end fitting of a backpack of this kind.
Tooth portions 4a and 4a are provided on the opposite side surfaces of the connecting plates 4 and 4 to which the respective three are attached, and the tooth portions 4a and 4a are meshed with each other to attach the connecting plates 4 and 4 to the back support portion 5a of the backpack 5. There is a structure in which each of the connecting plates 4 and 4 is attached so as to be swingable and has an inward elastic force.

A connecting plate 4 for the upper end fitting of the shoulder belt,
4 is sandwiched between the upper and lower covering plates 6a and 6b. If a gap is formed on the upper side, dust and dirt will enter and interfere with the swinging of the connecting plates 4 and 4. The upper and lower cover plates 6a, 6 are formed by projecting closing pieces 4d, 4d on the
There is no gap on the upper side between b. When the connecting plates 4 and 4 swing and spread outward,
The closing pieces 4d, 4d are respectively inserted into the escape spaces 30, 30 provided between the upper and lower covering plates 6a, 6b.

Further, the shoulder belt upper end fitting is
Rivet holes 31 provided at the upper ends of both ends of the upper cover plate 6a
a, 31a and a rivet hole 3 provided at the center of the upper end
The rivets 17, 17 and 17 are penetrated from 2a to the rivet holes 31b and 31b provided at the upper ends of both ends of the lower cover plate 6b and the rivet hole 32b provided at the center of the upper end, respectively, and the backrest of the backpack 5 is rested. It is riveted to a stop plate 20 attached to the back side of the portion 5a.

In the shoulder strap upper end fitting thus constructed, the mounting position of the shoulder strap 1 on the mounting rings 3 and 3 is within the swing width of the connecting plates 4 and 4 according to the physical constitution of the user. Since it is possible to move the same width in the left-right direction and the inward elastic force applied to the connecting plates 4 and 4, it is possible to maintain the attachment rings 3 and 3 in a state according to the physique of the user. It was very easy to use and had the effect of not giving the user a feeling of pressure or fatigue.

[0006]

However, in the above-mentioned conventional shoulder belt upper end fitting, the escape spaces 30, 30 into which the closing pieces 4d, 4d of the connecting plates 4, 4 enter are provided between the upper and lower covering plates 6a, 6b. Since they are provided, there is a problem in that the upper portions of both side ends thereof are overhanging, which makes them bulky.

Further, in the above-mentioned conventional shoulder strap upper end fitting, rivet holes 31a, 31a, 31b, 31b are provided on upper portions of both side ends of the upper and lower covering plates 6a, 6b, respectively, so that the back support portion 5b of the backpack 5 is provided. Due to the rivets, the upper and lower ends of the upper and lower covering plates 6a and 6b are further bulged, which not only increases the bulk but also deteriorates the appearance.

Therefore, the present invention is to solve the above-mentioned problems of the prior art by preventing the upper portions of both side ends of the upper and lower covering plates from overhanging and providing rivet holes in the upper portions of both side ends of the upper and lower covering plates. The object of the present invention is to provide a compact and good-looking shoulder strap upper end fitting for a shoulder bag.

[0009]

Therefore, in the shoulder strap upper end fitting of the backpack according to the present invention, the teeth 4a and 4a are provided on the opposite side surfaces of the connecting plates 4 and 4 to which the fitting rings 3 and 3 are respectively attached. , These tooth portions 4a, 4a are meshed with each other to attach the connecting plates 4, 4 to the back support portion 5a of the backpack 5 so as to be swingable, and the connecting plate 4,
4 are each provided with an inward elastic force, and flexible tongues 4c, 4c are projectingly provided on the outer end upper portions of the connecting plates 4, 4, respectively, and between the upper and lower covering plates 6a, 6b. When the connecting plates 4 and 4 oscillate and spread outward, the tongues 4c and 4c are provided above the supporting portions 12 and 12 of the lower cover plate 6b so that no gap is formed on the upper side. The sliding parts 16 and 16 are bent.

Further, the shoulder belt upper end fitting of the backpack according to the present invention includes the space portions S and S in which the springs 11 and 11 for pressing the outer surfaces 4b and 4b of the connecting plates 4 and 4 inward are mounted. The upper cover plate 6a is provided with rivet holes 18a, 18a so that the rivets 17, 17 can pass, and the lower cover plate 6b is provided with rivet holes 18b, 18b.
Further, rivet holes 19a and 19b are provided in the upper central portions of the upper and lower covering plates 6a and 6b, and the rivet holes 18a and 18b, the rivet holes 18a and 18b, and the rivet holes 19a and 19b are provided with rivets 17, 17 and 1, respectively.
It is possible to allow 7 to pass through and rivet to a stop plate 20 attached to the back side of the back support portion 5b of the backpack 5.
