  2. Description of the Related Art Conventionally, there is a back support member for a backpack type bag such as a backpack, such as a school bag, a rucksack, etc., in which a cushion material made of foam such as sponge is inserted to soften the contact with the back (for example, patent document) 1).

  Although the cushioning material can maintain elasticity for a long period of time, it may feel hard when used for a long time for the user, and it is not necessarily comfortable to carry on the back. A backing member that can provide cushioning properties has been desired.

In addition, since this type of conventional backing member contacts the user's back widely, there is a problem that the breathability is poor and the feeling of use deteriorates because the back is stuffy during long use. there were. Furthermore, the fabric itself on the side in contact with the back has poor air permeability, and it has been desired to improve air permeability.
JP-A-6-269310

  In view of the above, an object of the present invention is to provide a back support member for a backpack-type bag having a soft cushioning property and excellent air permeability.

  In order to solve the above problems, the present invention takes the following technical means.

  The back support member of the backpack according to the present invention is a back support member for a backpack provided at a location where the user hits the back when the user carries the backpack. The front side fabric 1 is made of a breathable fabric, and the portion of the front side fabric 1 where the convex portions 3 are formed has a hollow portion 4 between the back side fabric 2.

  The part which formed the recessed part 5a, 5b, 5c, 5d of the front side cloth | dough 1 shall be a groove | channel which does not contact a user's back.

  The front fabric 1 can be made of mesh-like synthetic fibers.

  The back support member of the shoulder bag according to the present invention has the above-described configuration, and the convex portion 3 is used while the air in the hollow portion 4 is released from the front fabric 1 by being pushed by the user's back. Because it contacts the back of the person, soft cushioning is obtained. In addition, since the front fabric 1 has air permeability, the back is less likely to be stuffy and the feeling of use is excellent.

  If the part which formed the recessed parts 5a, 5b, 5c, 5d of the front side cloth | dough 1 is a groove | channel which does not contact a user's back, air permeability will become more excellent.

  Preferred embodiments of the present invention will be described below with reference to the drawings.

  The back support member of the backpack according to the present invention is a back support member for a backpack provided at a location where the user hits the back when the user carries the backpack. The front side fabric 1 is made of a breathable fabric, and the portion of the front side fabric 1 where the convex portions 3 are formed has a hollow portion 4 between the back side fabric 2.

  FIG. 1 is a front view of a backpack bag (school bag) provided with a backrest member for a backpack bag according to an embodiment of the present invention, FIG. 2 is a perspective view thereof, and FIG. 3 is a perspective view of an exploded state of the backrest member. FIG. 4 is a sectional view.

  The back support member of the bag-type bag is, for example, a pair of shoulder belts 6 as shown in FIGS. 1 and 2, with the attachment portion 7 of the shoulder belts 6 facing upward from the school bag body 8. Can be used for other school bags. This school bag is similar to the school bag described in the specification and drawings of Japanese Patent Application No. 2002-347374, which is a prior application of the present application, and a pair of left and right connecting bodies of the attachment 10 provided on the backrest portion 9 of the school bag body 8. A pair of shoulder belts 6 each holding an elastic member (not shown) close to the attachment portion 7 are attached to the upper end of 11 with the attachment portion 7 of the shoulder belt 6 facing upward from the school bag body 8. It is.

  In the school bag, the shoulder belt 6 is directed upward from the school bag body 8 due to the above-described configuration. When the user carries the shoulder bag, the school bag body 8 is always pulled obliquely upward. Therefore, the backrest 9 is kept in close contact with the back of the user.

  The front fabric 1 is made of a mesh-like synthetic fiber, and can be, for example, a mesh fabric knitted using nylon as the warp and polyethylene as the weft. A plurality of dents that protrude from the back side to the front side (side that contacts the user's back) are formed on the front fabric 1, and the portions where these dents are formed are defined as convex portions 3. The portions that are not formed are recessed portions 5a, 5b, 5c, and 5d. The convex portion 3 can be formed by embossing the front fabric 1 with a heated mold.

  The front-side fabric 1 formed in this way can have the recesses 5a, 5b, 5c, and 5d freely intersected vertically and horizontally. In this embodiment, the concave portion 5a, 5b extending from the upper end side to the lower end side extending downward from the left and right ends of the bottom downward from the portion where the central shoulder belt fixture 10 is fixed, and substantially at the center. Two recesses 5c and 5d extending from the left end side to the right end side are provided.

  The concave portions 5c and 5d extending from the left end side to the right end side are both gently arcuately curved downward, and, of the convex portion 3, the convexity of the triangle inside the concave portions 5a and 5b respectively extending to the left and right ends of the bottom The part 3a is provided so as to pass through a position that divides the distance from the top to the bottom into approximately three equal parts.

  The concave portions 5c and 5d extending from the left end side to the right end side are in the horizontal direction when the user carries the shoulder bag, so that it is easy for the wind to pass therethrough and is suitable for ensuring air permeability. Further, the 5a and 5b extending respectively to the left and right ends of the bottom can reduce the contact surface between the front fabric 1 and the user and release the heat, thereby improving the feeling of use of the shoulder bag.

  Furthermore, since the front side fabric 1 has a configuration that is vertically and horizontally partitioned by the convex portion 3 and the concave portions 5a, 5b, 5c, and 5d as described above, the shape retaining property is good and the convex portion 3 is difficult to loosen. The state having the hollow portion 4 can be maintained for a long time.

  Note that the recesses 5a, 5b, 5c, and 5d may be formed in a straight line without being curved, and the position can be changed as appropriate. Furthermore, it can also be provided obliquely along the diagonal line of this backrest member. Further, the number of the recesses 5a, 5b, 5c, 5d is not particularly limited.

  The difference in height between the top of the protrusion 3 and the bottom of the recesses 5a, 5b, 5c, 5d is about 1 to 2 cm, and the triangular protrusion 3a inside the recesses 5a, 5b extending to the left and right ends of the bottom is It is made slightly lower to create a gap between the user's back and make it less likely to get stuffy. The width of the recesses 5a, 5b, 5c, 5d is about 1 cm at the bottom, and widens upward. The sizes of the convex portion 3 and the concave portions 5a, 5b, 5c, and 5d may be adjusted according to the shape of the user's back and various other use conditions.

  As shown in FIG. 4, the convex portion 3 has a hollow portion 4 between the convex portion 3 and the back side fabric 2. By this hollow portion 4, the front fabric 1 softly hits the user's back.

  The back side fabric 2 is a rectangular foamed urethane sheet having a thickness of about 5 mm, but is not limited thereto, and may be made of a nonwoven fabric. The front side fabric 1 is attached by heat-welding the back side fabric 2 to the back side of the portion provided with the peripheral edge portion or the recesses 5a, 5b, 5c, 5d. By the heat welding, the front side fabric 1 can be easily attached to the back side fabric 2 and a firm and secure fixing state can be obtained, so that the front side fabric 1 is not easily peeled off from the back side fabric 2. The front side fabric 1 may be attached to the back side fabric 2 by sewing.

  Moreover, this back support member can fix the back side fabric 2 to a back plate (not shown). Fixing to the back plate can be performed by an appropriate method such as bonding with an adhesive or sewing. The back plate can be a quadrangular plate made of a material having an appropriate rigidity, such as plastic or veneer. It is desirable that the back plate has elasticity.

  The back support member of the bag-type bag is pushed against the user's back so that the air in the hollow portion 4 is released from the front fabric 1 and the convex portion 3 contacts the user's back. It hits the user's back softer than the one used. Accordingly, a soft cushioning property can be obtained, and it is difficult for the user to be painful even in a state of being in close contact with the user's back for a long time. In addition, since the front fabric 1 has air permeability, the back is less likely to be stuffy and the feeling of use is excellent.

  In addition, the portions where the recesses 5a, 5b, 5c, and 5d are formed are grooves that do not contact the user's back, and a gap is formed between the backrest member and the user's back, so air permeability is further improved. The back is hard to stuffy.

  In addition, the dimension, the shape, etc. of the front side fabric 1 and the back side fabric 2 are not limited to the above-described configuration, and can be implemented with appropriate changes.

  It can be used for backpacks such as school bags and rucksacks.
