Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rucksack, and more particularly to a rucksack whose storage capacity can be changed according to the amount of stored items.

[0002]

2. Description of the Related Art Conventionally, Japanese Utility Model Publication No. 3-50731 has been proposed as a backpack of this type. The conventional rucksack has the following structure as described in the scope of claims for utility model registration. `` The bag-like body of the bag-shaped body consisting of the backpack surface and the bottom surface and both side surfaces following this and the back surface continuing to the bottom surface, the bottom surface continuing to this backpack surface, the back surface continuing to this bottom surface, and the bag at the connecting portion with the side surface. The folded folds are continuously provided inward of the bag-shaped body, and the back-side surfaces, the bottom surface, and the back surface of the bag-shaped body on the edges of the side in contact with the gussets have a pair of male and female threads. A rucksack provided with a fastener, and by opening the fastener, the bag-shaped main body can be expanded toward the backpack surface, the back surface, and both side surfaces. "

[0003]

However, the accommodation capacity adjusting type rucksack using this type of fastener is
First, there is a problem that the fastener is easily damaged. That is, the above-mentioned conventional rucksack has a series of one side fastener strips attached to three sides excluding the upper side of the side surface,
The other side fastener strips that engage with the one side fastener strips are attached to both left and right sides of the backpack surface, the bottom surface, and the back surface, and a U-shaped bendable band-like gusset having a predetermined width that normally connects the side surface and the bag-shaped main body is attached. Since the fastener strips on one side and the fastener strips on the other side are folded by bending inward, the start end and the end of the fastener closed in this state are located in the upper opening of the bag-shaped main body.

When the fastener is forcibly opened at the starting end or the rear end (for example, a force acting to inflate the main body with a stored item), the engagement and disengagement is relatively easy. In this way, if the small piece for meshing (hereinafter referred to as the element) is disengaged regardless of the slider for opening and closing, the possibility of disengagement of the element increases when the slider for opening and closing is tried to open and close next time. This is because it may be damaged. In addition, the side that starts to open with the opening / closing slider usually slides with this opening / closing slider even if a force to open the fastener other than the temporary slider acts, so in this case there is little risk of damage, but from now on If the element of the portion to be opened by the opening / closing slider is already out of engagement, the opening / closing slider is not configured to engage the elements by reversing, so that an excessive force is applied. The meshing of the elements will shift.

Next, this type of backpack has a problem that the shape of the entire backpack tends to collapse when it is expanded. In Japanese Utility Model Publication No. 3-50731, "the bag-shaped main body can be expanded toward its back surface, back surface and both side surfaces", but since the gusset is not folded between the bottom surface and the back surface, The upper opening extends substantially evenly toward the back surface, the back surface, and both side surfaces, but the bottom surface side tends to expand more toward both side surfaces. That is, when viewed from the front, it has an extreme tendency to have a drawstring bag shape or a trapezoid shape with the upper mouth closed. Usually, since the backpack of the backpack is fixed to the upper center of the backpack and the upper end of the backpack is carried on the back, it becomes a single-point hanging state when carrying it on its back, and the left and right sides of the expanded body hang downward. It is what makes the appearance worse.

Therefore, the present invention has been made to solve the above-mentioned problems, and changes the storage capacity in which the expanding fastener is less likely to be damaged, and which does not lose its shape even when it is expanded and is in another state and carried on its back. It is intended to provide a possible backpack.

[0007]

[0012]

Embodiments of the present invention will now be described with reference to the accompanying drawings. In the figure, 10a is a main body main portion, and the main body main portion 10a is configured by sequentially connecting a main body back plate surface 11, a main body bottom surface 12 and a main body front surface 13 (because the main body back plate surface 11 is on the back side of FIG. 1). See FIG. 4).

The main body back plate surface 11, the main body bottom surface 12, and the main body front surface 13 may be made of conventionally known materials by a conventional method, and even if a series of fabrics are bent, the respective parts are made of appropriate materials. It may be prepared and sewn, but since the main body back plate surface 11 is a surface that comes into contact with the back when carrying the back,
If a conventionally well-known cushion material is stored in the double structure, the wearing feeling will be good.

On the left and right sides of the main body portion 10a of the main body, a gore member having four sides of a side face 25, which is made of a bendable cloth, has a gore rear face 21, a gore bottom face 22, a gore front face 23, and a gore upper face 24 which are connected in a ring shape. Side and gusset bodies 20 and 2 sewn on one side of 20a
0, the left and right other sides of the gore member 20a to the main body portion 10
The main body 10 is constructed by sewing and attaching to the left and right sides of a. In FIG. 1, the gore member 20a is woven inside, and therefore hidden behind the fastener 30 and invisible. The rear surface 21 of the gusset is the back side of "Fig. 2"("Fig.4"
See).

The side face / grape body 20 has a main body portion 10a.
The four sides of the side surface 25 of the gusset are joined together in a ring shape with the back 21 of the gusset, the bottom 22 of the gusset, the front 23 of the gusset, and the top 24 of the gusset, which are made of a bendable fabric. The left and right sides of the gusset member 20a can be sewn together. The left and right other sides of the gore member 20a, that is, the opposite side to which the side surface 25 of the gore member 20a is sewn, are sewn and attached to the left and right sides of the main body portion 10a to form the main body 10. The left and right sides of the rear side 21 of the back of the gusset are on the left and right sides of the back plate surface 11 of the body, the left and right sides of the bottom of the gusset 22 are on the left and right sides of the bottom surface of the body 12, and the other sides of the front 23 of the gusset are left and right sides of the front side of the body 13. The side edges are sewn, respectively, and the left and right other sides of the upper surface 24 of the gore are attached to the base end portion of the lower cloth of the extending portion of the lid surface 40 described later or the lid surface 40.

A pair of fastener strips 30a and 30b, which mesh with each other, are provided on the gusset member 20a and the gusset front surface 23.
From the center part slightly lower than the upper end of the gusset toward the upper side of the gusset member 20a in order upward, and along the both sides of the gusset member 20a from the upper end of the gusset front face 23 to the gusset upper face 24 and the gusset rear face 21.
To the bottom 22 of the gusset, and also on the front 23 of the gusset along both sides of the gusset member 20a, and the end of the gusset member 20a is attached so as to reach a portion above the starting end.

That is, the fastener strips 30a, 30
b is a pair and constitutes the fastener 30 which is opened and closed by the slider 31. And, as shown most clearly in "Fig. 2", the attachment start end of this fastener 30 is located at a central portion slightly lower than the upper end of the gore front face 23, and from the attachment start end upwardly of the gore member 20a. The front side 23 of the gusset is spread out toward both sides.
(The tape with the element attached is sewn on). Further, from the upper end of the front side 23 of the gore, the fastener strip 30a on one side is a seam between the side face 25 and the gore member 20a,
Alternatively, the fastener strip 30b on the other side is adapted to sew the respective tape portions together at the sewn portion between the gusset member 20a and the main body main portion 10a. In addition, at the side of the main body main part 10a side of the gusset upper surface 24, the tape portion is sewn together with the sewn portion between the gusset upper surface 24 and the lid surface 40.

Therefore, the fastener 30 has the side surface 2
One round is made along the peripheral edge of 5, and the mounting start end side and the mounting end side are partially overlapped. The fastener 30 is relatively easily disengaged when an external force is applied to its end in the opening direction.
The meshing on the way has the property that it cannot be easily disengaged even if an external force is applied. Therefore, by partially overlapping the attachment start end side and the end end side of the fastener 30 with each other, it is possible to prevent the end side of the fastener 30 from being unintentionally detached even if the main body 10 swells in the stored item.

A lid surface 40 having a fastener opening / closing opening 42 in the central longitudinal direction is provided at the upper opening of the main body 10,
One side locking tool 41a is attached to both ends of the lid surface 40, and a connecting distance capable of being removably locked to the one side locking tool 41a is provided on the side surface 25 or the lateral pocket 26 mounted on the side surface 25. Adjustable other side locking tool 41
b is attached. The lateral pocket 26 may be a conventionally known one, but the lateral pocket 26 is shown in the figure.
Although not shown in the drawing, has a lid 26a that can be opened and closed with a fastener at the upper end, and this fastener is covered with a fastener covering material 26b hanging from the peripheral edge of the lid 26a.

The lid surface 40 may be formed in a rectangular shape, and the upper side of the back plate surface 11 of the main body, the upper side of the front surface 13 of the body, and the other side of the upper surface 24 of the gusset may be sewn to the four sides thereof. Then, on both sides of the lid surface 40, extended portions 43 protruding in a triangular shape are connected to the outside of the main body 10. The reason for providing this extended portion 43 is that this type of fastener opening / closing lid is capable of reliably sealing the opening and wide opening the opening. This is because it can be used.

Therefore, since the base end portion of the extended portion 43 cannot achieve its purpose by being attached to the main body 10, the extended portion 43 is not necessarily clear from the drawing, but its oblique side portion is sewn. It has a double structure, the upper fabric is sewn to the main body 10 leaving the extended portion 43, and the base end of the lower fabric of the extended portion 43 is sewn to the gore member 20a. The opening / closing port 42 is formed so as to be provided in the entire width of the main body 10 or a length equal to or more than the entire width.
The opening can be widened to make it easier to put items in and out.

As the one-side locks 41a attached to both ends of the lid surface 40, a conventionally known plug-in lock is used in the illustrated example, but other hooks, buckles, locks, and surface fasteners are used. Etc. may be used. Also,
Of course, the other side locking tool 41b is used as a pair with the one side locking tool 41a, but the one side locking tool 41a and the other side locking tool 41b are the one side locking tool 41a and the other locking tool. The distance connected via the side locking tool 41b can be adjusted. In order to make the distance to be connected adjustable, in the illustrated example, the base end portion of the attachment band 27 is fixed to the lateral pocket 26 attached to the side surface 25, and the other side locking device is attached to the attachment band 27. 41b is attached so that the attachment position can be changed. That is, in the illustrated embodiment, by moving the other-side locking tool 41b to an appropriate position of the attachment band 27, the distance between the one-side locking tool 41a and the part connected through the other-side locking tool 41b is increased. It is adjustable.

In order to attach the other side locking tool 41b to the mounting band 27 so that the mounting position can be changed, as is well known in the art, the other side locking tool 41b is provided with an empty portion provided with a belt folding bar at the center. It suffices to insert the free end of the attachment band 27 into the space from the lower front of the belt folding bar, fold it back by winding the belt folding bar, and then insert it from the upper rear of the belt folding bar into the cavity. .

If hooks are used for the one-side locking tool 41a and the other-side locking tool 41b, it is sufficient to prepare a plurality of the hooks and change the locking positions. When using the buckle, A plurality of dowel holes may be prepared, or one having a conventionally well-known structure that can be locked to the buckle itself without permission may be used. Further, since the present invention is a kind of beauty tablet in the present embodiment, the same constitution may be used, and in the case of a surface fastener, a sheet fastener having a predetermined length may be appropriately used. The locking position can be adjusted, and the connection distance can be adjusted.

A slider locking tool 33a on one side is connected to the knob 32 of the slider 31 which opens and closes the fastener strips 30a and 30b, and the slider locking on one side is locked at a central portion slightly lower than the upper end of the rear surface 21 of the gusset. The other side slider locking tool 33b to which the tool 33a is locked is attached.

The one-side slider locking member 33a and the other-side slider locking member 33b are used as a lock in the illustrated example, and are attached to the knob 32 of the slider 31 via a connecting piece 34. In addition, this one side slider locking device 33
It is needless to say that the a and the other side slider locking device 33b may use various conventionally known detachable locking devices other than the lock.

The one-side slider locking member 33a and the other-side slider locking member 33b are for making the fastener 30 close only at the upper portion of the side surface 25 and open at the lower portion, as shown in FIG. Then, the bottom of the main body 10 bulges,
The upper part can be formed into a trapezoidal shape.

In the figure, 52 is a cover, and 52a, 52.
Reference numeral a is a cover lid locking tool for locking the free end of the cover lid 52 to the main body 10. As in the present invention, a lid surface 40 having a fastener opening / closing opening 42 in the central longitudinal direction at the upper opening of the main body 10
In the system provided with, the rain may enter from the fastener opening / closing port 42, so it is desirable to cover the upper part with the cover 52. It should be noted that the cover lid locking tool 52a uses a pair of locking tools, and one side is covered with the cover lid 52.
It is attached to the lower end of the belt 55, and the other side is attached to the free end side of the belt 55 fixed to the upper end of the front pocket 53, which will be described later (see FIG. 1 to FIG. 3 with reference numeral 55). The attached part covers the belt 55 and the lid locking device 52.
The free end part folded back from a is shown, and the base end side of the belt 55 having the lower end sewn together with the lower end at the upper end sewn part of the front pocket 53 is present on the back side of this figure. ) Same as conventional.

Further, 51, 51 are shoulder straps, and this shoulder strap 51 (one side is shown in the figure, but one pair is of course prepared) has its upper end fixed to the upper center of the body back plate surface 11. The lower end is the lower part of the back plate surface 11 of the main body or the bottom surface 1 of the main body.
It is the same as the conventional one so as to be connected to 2.
Further, in the figure, 54 is a hand grip and 53 is a front pocket, which are attached as required.
