Description

[Detailed description of the invention] [Purpose of the invention] Industrial application field The present invention is to develop a back surface of the backpack that fits the back surface of the human body when the backpack is carried on the back and maintains its rigidity. The present invention relates to a frame device.

BACKGROUND ART As a conventionally known frame device for carrying a backpack, there is a utility model application published in 1988-101, the name of which is ``back frame device for carrying a backpack''. As shown in FIGS. 7 and 8, the above-mentioned device constitutes a bag-shaped part 2 for inserting a back support frame 3 in the vertical direction on the inner or outer surface of the back surface 1' of the backpack 1. This is a backpack frame made by inserting a soft elastic sheet 4 on both or one side of a back support frame 3 and a polymer covering the end periphery of the back support frame.

Problems to be Solved by the Invention The above-mentioned backpack support frame device not only allows the back support frame to be easily attached and removed, there is no movement of the back support frame, and hits the human body gently; Although it has the effect of preventing bending and making it easier to carry on your back,
The bending degree of the curve provided on the back support frame is constant, and its elasticity acts only in the front and back direction with respect to the backrest surface. It is difficult to perform a fit that corresponds to the subtle differences in the shape of the back of the human body, and there are drawbacks such as the load hitting the back.

This invention allows the frame to bend back and forth, left and right, or twist, depending on the subtle differences in the shape of the back of the human body, which varies from person to person. The back surface, which is stretched under tension by the frame, does not come into direct contact with the surface part, but the back surface is in tension, and the back surface of the backpack fits according to the shape of the back of the human body, which differs from person to person.
To provide a frame device for a back surface of a backpack that creates a sense of unity between the human body and the backpack, does not cause back contact due to a load, and does not hinder the human body's actions.

[Structure of the idea]

In order to achieve the above-mentioned object, the present invention provides a pouch-like part for inserting and removing a rod-shaped frame in the vertical direction of the corner formed by the backpack surface and both side surfaces, and the rod-shaped frame has a flexible structure. This device has a frame device for carrying a backpack and is characterized by being made of a material with torsion and rigidity.

Embodiment The embodiment shown in the drawings above will be described as follows.

As shown in FIG. 4, rod-shaped frames 18 are placed on the left and right sides of the back surface sheet 12, which is cut into a shape that forms the back surface 11d of the backpack 11, in the longitudinal direction.
As shown in FIG. 14' to the side sheets 11b, 11c of the rucksack 11 and the back side open edges 11b', 11
It is fixed to c' by sewing or other means to form a backpack zag 11 as shown in FIGS. 1 and 2. 1
1a is the front of the lid, 15 is the lid, 16,
17 is a backpack belt. In the illustration, the bag-shaped parts 13 and 14 are located in contact with the side sheets 11b and 11c, but they are positioned in the direction shown in FIGS. It is also designed so that it can be A rod-shaped frame 18 is inserted into the bag-shaped portions 13 and 14 as shown in FIG. As shown in FIG. 6, the rod-shaped frame is given flexibility and twistability, and the back sheet 11d of the backpack 11 is always kept stretched in a predetermined shape, so it has rigidity. has been granted.

The embodiment shown in the above drawings is
The bag-shaped parts 13 and 14 provided on the left and right sides of the back sheet 11d, that is, the backpack 12, were bent inward of the backpack, and the folded edges 13' and 14' were sewn to the side sheets 11b and 11c of the backpack 11. Although the embodiment has been shown, the bag-like portions 13 and 14 are bent outward of the bag 11, and the bent edges are connected to the back side open edges 11b' and 11 of the side sheets 11b and 11c.
c′ by sewing or other means, and
4 may appear on the back sheet 11d of the backpack 11, that is, on both left and right sides of the outer surface of the bag 12. Moreover, the bag-shaped parts 13 and 14 are
The back side open edges 11 of the side sheets 11b and 11c of
b', 11c', or the side sheet 11
b, 11c, one edge of the bag-shaped portions 13, 14 formed separately from the back sheet 12 is attached to the side sheets 11b, 1.
It may be sandwiched between 1c and the back sheet 12.

[Effect]

In the present invention, the rod-shaped frames 18, 18, which are flexible, torsional, and rigid, are arranged vertically at the corners formed by the left and right sides of the back surface 11d of the backpack 11, and both sides 11b, 11c of the backpack 11. Since it is housed in the bag-shaped parts 13 and 14 provided in the direction, the rod-shaped frame can not only be bent back and forth, left and right, but also twisted or bent as shown in Fig. 6. Back sheet 11d that can be twisted and stretched between frames in accordance with the subtle differences in the shape of the back of the human body that differs from person to person.
That is, it is possible to respond to 12 delicate changes, and it is also possible to maintain the tension of the backpack seat, and it is possible to obtain a frame device for the backpack seat that does not hit against the back due to a load.
