Description

[Detailed Description of the Invention] <Industrial field of application> The present invention relates to an improvement of a backpack bag, and in particular, by deforming the bag body, it can be carried by hand while storing a large number of items. It was devised so that it could also be used.

<Prior art> Regarding the bag that can be used both as a backpack type and a handbag type,
Japanese Utility Model No. Sho 60-36722 is proposed.

And, in this structure, the brackets (4) (4 ') with lead grooves are installed on the inclined top plate (2) of the bag body (a), while the handles (1) (1) The movable mounting bracket (5) (5 ') is attached to one end of
(5) and (5 ') are designed to slide along the lead grooves of the receiving brackets (4) and (4').

<Problems to be solved by the device> However, in the case of the above-mentioned known device, the inclination of the top plate (2) and the pair of left and right brackets (4) (4 ') having a lead groove are It is an indispensable condition to arrange in an array in the shape of a letter, and along the lead groove, the mounting bracket for the handle (5)
The slanted top plate (2) is literally made of a material which is not flexible as is known in school bags and the like, because the slanted top plate (2) is automatically slid by the weight of the bag body (a). Must be made as a board.

Moreover, since the chucks (3) are arranged in rows on such an inclined top plate (2), it is not possible to open the bag main body (a) to a large extent, and it is possible to accommodate a large item or a solid item. However, it is difficult to smoothly take in and out the product. This can be said from the fact that the bag body (a) of the above-mentioned known device has no change in its overall size and shape between when it is used on its back and when it is used as a handbag.

Further, in addition to the chuck (3), a pair of left and right brackets (4) and (4 ') having lead grooves are arranged on the inclined top plate (2) so that they are always exposed. Since the lead groove has a literal groove shape, it is exposed to rainwater and dust, especially during outdoor use as a hand-held type, and rusts quickly, and the above-mentioned mounting brackets (5) (5 ') The problem of obstructing the sliding action of is likely to occur.

<Means for Solving the Problem> The present invention intends to improve such a problem, and in view of its structure, a bag body made of synthetic resin, synthetic leather, or other flexible cloth material is provided with a pair of left and right parts. In a backpack type bag with a backpack band attached, the bag body is a substantially rectangular back surface exposed to the outside when the backpack is used, and an upper surface and a lower surface of a substantially isosceles triangle having a bottom portion continuous with each short side of the back surface. And a vertical vertical triangular column surrounded by both sides of a substantially isosceles trapezoid with a short upper base that is continuous with each long side of the back, and the top and bottom vertices As if connecting the two parts together, the bag body carries the long lower bottom part on both sides that extends equally upward and downward from the short upper base part of the above-mentioned isosceles trapezoid and extends on the back of the human body when used. Ventral surface to touch Then, slide fasteners for loading and unloading items are arranged along the longitudinal centerline of the abdominal surface, and the fasteners are located at both ends of the slide fastener and from the top and bottom vertices of the above-mentioned isosceles triangle. Mounting ear pieces for use as a unit, and attach a pair of male and female fasteners consisting of eyelet hooks or buckles that can be engaged and disengaged to each other, while attaching the upper ends of both shoulder straps to the bag. Attached and fixed together with the hanging strap through the reinforcing seat to the center position close to the bisector of the upper surface of the main body, similarly distributing the lower ends of both shoulder straps to the left and right end positions of the lower surface of the bag main body When the fasteners are locked to each other, the upper surface and the lower surface of the bag main body are attached to each other from the apexes of the isosceles triangle. It can be folded flat inward and can be used on the back while the slide fastener on the abdominal surface is covered, and when the fastening state of the fastener is released, the top and bottom surfaces of the bag body have their apexes. It is characterized in that it is restored to an isosceles triangle so as to project to the outside of the portion, and that the slide fastener on the abdominal surface can be handheld and used under an exposed state in which it is tensioned.

<Operation> According to the above configuration of the present invention, the bag body is made of a soft cloth material, the upper surface and the lower surface of which are substantially isosceles triangles, and both side surfaces are also formed into a substantially isosceles trapezoid. Moreover, the short upper base of the isosceles trapezoid is continuous with the rectangular back surface of the bag body, while the same long lower base is the abdominal surface of the bag body, which is used for loading and unloading items along the longitudinal centerline of the abdominal surface. In addition to the slide fasteners arranged in an array, the male and female eyelets or buckles are attached to the mounting ear pieces for fastening metal fittings that are located at both ends of the fasteners and project from the apexes of the upper and lower surfaces forming the above-mentioned isosceles triangle. A pair of fasteners are attached.

Therefore, when the locked state of the fastener is released,
Based on the difference in length between the lower base and the upper base that form the isosceles trapezoid on both sides, the abdominal surface of the bag body overhangs more than the back surface as shown in Fig. 1, and the upper and lower surfaces of the bag body are Restore to an equilateral triangle. As a large-capacity bag body as shown in Fig. 1, it can be used as it is by carrying a backpack band, and in that case, by sliding a slide fastener that extends long in a tension state on the abdominal surface. Therefore, even large items and solid items can be easily put in and taken out.

Further, when the fasteners are locked, the upper and lower surfaces of the bag body are bent and deformed inwardly and flatly from the respective apexes as shown in FIG. 4 to keep the slide fastener on the abdominal surface covered. Therefore, the bag body in the deformed state shown in FIG. 4 can be carried on the back by the above-mentioned backpack band.

At that time, as described above, the abdominal surface of the bag body overhangs more than the back surface by the length corresponding to the difference in length between the lower base part and the upper base part that form the isosceles trapezoid on both sides, and is fastened. Since the metal fittings are attached to the mounting ear pieces that project from the tops and bottoms of the above-mentioned isosceles triangle, the bag body can be deformed as shown in FIG. Nothing.

Furthermore, since the above-mentioned fastener is made of an eyelet hook or a buckle, it does not require a troublesome binding and tying operation like a cord, and can be engaged and disengaged under a so-called one-touch operation. As described above, the sealed state of the bag body can be firmly locked and maintained without the risk of disengagement.

In addition, the upper end of the backpack band is attached and fixed together with the hanging strap through the reinforcing seat at approximately the center position of the upper surface of the bag body that is an isosceles triangle. Since it is attached and fixed to both left and right positions in a distributed state, it is not necessary to change the mounting position of the backpack band, only the flexible bag body is deformed as shown in Figs. 1 and 4, and the backpack band can be used as a carrying band as it is. It can also be used as a handbag while also serving as a dual purpose.

<Embodiment> The specific construction of the present invention will be described in detail below with reference to the embodiments of the drawings. FIGS. 1 to 4 show the entire bag of the carrying type, and (M) is nylon, vinyl chloride, or the like. It is a bag body that is quilted or waterproofed with synthetic resin, synthetic leather, or other flexible sheet material as a fabric, and because it has flexibility, its appearance may be different depending on the stored items. Although it will change to some extent, the back (1
1) and the abdominal surface (15) which is also in contact with the back of the human body.

That is, as suggested by FIG. 5 in which the bag body (M) is extracted, these back surfaces (11) are formed as a substantially elongated rectangular shape in the vertical direction, and the pair of short sides facing each other are substantially formed. Top (14) and bottom (15) that form an isosceles triangle
Each bottom part of the is sewn by the sewing thread (16). Also, the symmetrical left and right side surfaces (13) have a substantially isosceles trapezoidal shape, and the short upper base part is the long side part of the back surface (11).
Both are continuous through the first bending ridgeline (a), and the inclined side portions of both side surfaces (13) are also the upper surface (14) and the lower surface (1).
The second and third bent ridgelines (b) and (c) to the inclined side of 5), respectively.
It is still continuous through.

In this regard, in FIG. 5, both side surfaces (13) and the back surface (11) of the bag body (M) are made into a predetermined continuous single piece, and the
Both sides (13) bent from the bent ridge (a) are continuously bent from the second and third bent ridges (b) and (c) to form half of the upper surface (14) and the lower surface (15). The sewing machine thread (17) is sewn on each of the bisectors of the upper surface (14) and the lower surface (15) of the above, but as shown in the alternative example of FIG. Both sides
(13) and the back surface (11) on the first bent ridgeline (a),
It is also possible to sew each of them together.

Furthermore, the long lower bottom part of the both sides (13) forming the above-mentioned isosceles trapezoid extends as a line segment connecting the apexes of the upper surface (14) and the lower surface (15), and a pair of left and right sides thereof in parallel. As a result, a band having a constant width is formed, which is set as the abdominal surface (12) in contact with the back of the human body in the bag body (M). (19) is a slide fastener for loading and unloading items arranged along the longitudinal centerline of the ventral surface (12),
By sliding the operation fitting (20), an item can be put in and taken out from the bag body (M).

In arranging the slide fasteners (19) in an array, in the figure, they are sewn to the above-mentioned parallel lower base parts of both side surfaces (13) with sewing thread, but instead of adhesive, heat seal, etc. The fixing means may be adopted. Such an alternative means is to use the upper surface (14) and the lower surface (15) for the back surface (11).
The same can be applied to the sewing of, and the sewing on the bisectors of the upper surface (14) and the lower surface (15).

As described above, both side surfaces (13) of the bag body (M) have an isosceles trapezoidal shape, and the short upper base portion of the bag body (M) is continuous with the long side portion of the back surface (11), while both sides are also the same. Since the long lower base portion of the surface (13) forms the abdominal surface (12) of the strip that functions as a so-called attachment base of the slide fastener (19), the abdominal surface (12) is the lower base portion and the upper base portion. As a result, a length dimension (L) double-headed by the difference between the length and the length of the back surface (11) causes the back surface (11) to equally project in the opposite vertical direction from the long side portion.

(21) is a pair of upper and lower located at both ends in the longitudinal direction of the slide fastener (19), and is integrally projected from each vertex of the upper surface (14) and the lower surface (15) forming the isosceles triangle. Attachment ear pieces for fasteners, to which a pair of male and female fasteners (22) (23) consisting of eyelet hooks as shown in FIG. 12 or plug-in buckles as shown in FIG. 13 are attached. .

In that case, it is preferable that one of the pair of male and female fasteners (22) and (23), which comes into contact with the back of the human body when carrying the backpack, is covered with a cushion cover (not shown).

Whether it is the eyelet hook or the buckle, the male and female pairs of the fasteners (22) and (23) can be engaged and disengaged from each other, and when locked, as shown in FIGS.
Both of the apexes of the upper surface (14) and the lower surface (15) forming the above-mentioned isosceles triangle are pulled inwardly opposite to each other, and correspond to the difference in length between the lower base portion and the upper base portion on the both side surfaces (13). Based on the overhang of the length dimension (L), it will be bent inwardly flat from its mid-height position.
Together with the mounting ear piece (21) of 3), the slide fastener (19) extending on the longitudinal centerline of the abdominal surface (12) is surely covered by itself. Then, under such a state, the bag body (M) is carried on the back and used.

In that case, even if it is assumed that the both side surfaces (13) of the bag body (M) are not formed into an isosceles trapezoid as described above but are formed into a rectangular shape, for example, the fasteners (22) and (23) are locked. At this time, it can be said that the upper surface (14) and the lower surface (15) forming an isosceles triangle can be bent inwardly flat from its mid-height position and can cover the slide fastener (19). Since there is no overhang of the length dimension (L) corresponding to the length difference between the lower bottom side and the upper bottom side like that, the upper surface (14)
And the lower surface (15) must be bent from the approaching position of the back surface (11) far away from both apexes, and the fasteners (22) (23)
Can not be locked, the capacity of the bag body (M) must be reduced, and the length of the slide fastener (19) extending to the abdominal surface (12) of the bag also becomes short.
It becomes difficult to put in and take out large items and solid items.

In this regard, according to the present invention, as described above, the upper surface (14) and the lower surface (15) of the bag body (M) not only have an isosceles triangular shape, but also the pair of left and right side surfaces (13) are particularly isosceles trapezoidal. The long lower base of the isosceles trapezoid is a slide fastener.
By forming the ventral surface (12) that functions as a mounting base for (19), the above problem can be solved.

On the other hand, if the fastening state of the fastening metal fittings (22) (23) is released,
As shown in FIGS. 2 and 3, the upper surface (14) and the lower surface (15) of the bag body (M) are restored to an isosceles triangle so as to project to the outside of each apex thereof, and further bent as shown in FIG. From the first, 7,
Slide fastener of the above-mentioned abdominal surface (12) to the straight state of FIG.
Since the (19) can also be tensioned, the slide fastener (19) in the exposed state is slid by the operating metal fitting (20), and both side surfaces (13) of the bag body (M) are moved.
The abdominal surface (12) formed from the long lower base part of the can be opened to a very large size in its fully opened state, and also large articles and solid articles can be smoothly taken in and out.

(24) is a pair of left and right shoulder straps, both of which have their upper end portions near the center of the upper surface (14) of the bag body (M) near the bisector, and are reinforced with leather or the like (25). ) Centrally attached and fixed. On the other hand, the lower ends of the backpack vans (24) are the lower surface (15) of the bag body (M).
It is attached and fixed to the left and right end positions of the in a distributed state, and the midway part where the length of the shoulder strap (24) can be adjusted is
The bag body (M) faces the abdominal surface (12).

In other words, both shoulder straps (24) are the slide fasteners
The longitudinal centerlines of the abdominal surfaces (12) arranged in rows of (19) are symmetrically arranged so as to be the boundaries, and therefore, in the state of carrying on the back by this, the abdominal surface of the bag body (M) ( 12) contacts the back of the human body in a well-balanced manner, and the back surface (11) is exposed to the outside.

In addition, it is possible to carry the bag body (M) in the state shown in Fig. 1 by carrying it by using both of the back carrying bands (24) as it is, as it is also used as a carrying band. It is possible to keep (M) in a larger capacity as compared with the state of carrying on shoulder as shown in FIG. Further, since the back surface (11) of the bag body (M) has a substantially rectangular shape, it is possible to stably set the back surface (11) as a ground plane when not in use.

In terms of stability for installation and use, the core material (26) as shown in FIG. 9 is installed by enclosing it in the back surface (11) of the bag body (M), or the core material (26) It is desirable to have the grounding feet (27) project from the corners. Reference numeral (28) is a hanging cord that also serves as the above-mentioned reinforcing seat (25) and is attached and fixed to the upper surface (14) of the bag body (M) together with the upper end of the backpack band (24),
Used for hanging when not in use or during natural drying.

In addition, since the back surface (11) of the bag body (M) is exposed to the outside when it is carried on the back, various characters and patterns are printed here, or a separate display film (not shown) on which the printing is performed is printed. It is also conceivable to integrate them by polymerization.
Further, it is preferable to install a cushion pad in the shoulder strap (24).

<Effect of the Invention> As described above, according to the present invention, in the backpack type bag in which the pair of left and right backpack bands (24) are attached to the bag body (M) made of the synthetic resin, the synthetic leather, and other flexible cloth materials, The bag body (M) has a substantially rectangular back surface (11) exposed to the outside when it is carried on a back and an upper surface (14) of a substantially isosceles triangle having a bottom portion continuous with each short side portion of the back surface (11). ) And the bottom surface (15), and both sides (13) of a substantially isosceles trapezoid with a short upper base that is continuous with each long side of the back surface (11). It is shaped like a column, and extends equally above and below the short upper base of the above isosceles trapezoid by a certain dimension (L) so that the tops (14) and bottoms (15) of the same are connected to each other. The abdominal surface where the bag body (M) bears the back of the human body when the bag body (M) is carried on the back with the long lower bottom part of the left and right side surfaces (13) remaining As (12), slide fasteners (19) for loading and unloading items are arranged along the longitudinal centerline of the belly surface (12), and the above-mentioned isosceles triangle is formed while being located at both ends of the slide fastener (19). From the top of each of the upper surface (14) and the lower surface (15), project the mounting ear pieces (21) for the fasteners integrally,
While attaching a pair of male and female fasteners (22) (23) consisting of eyelets and buckles that can be engaged and disengaged with each other to the both mounting ear pieces (21), the upper ends of the both shoulder straps (24) are attached to the bag. At the center of the body (M), which is close to the bisector of the upper surface (14), it is attached and fixed together with the hanging string (28) through the reinforcing seat (25), and the two shoulder straps (24) are also provided. The bottom end of the bag body (M) is attached and fixed to the left and right ends of the lower surface (15) of the bag body (M) so that when the fasteners (22) and (23) are locked together, the bag body (M ) The upper surface (14) and the lower surface (15) of the isosceles triangle are bent inward from both apexes and are covered with the slide fastener (19) of the abdominal surface (12). It can be used, and when the fasteners (22) (23) are released from the locked state,
The upper surface (14) and the lower surface (15) of the bag body (M) are restored to an isosceles triangle so as to project outward of their respective apexes, and the slide fastener (19) on the abdominal surface (12) is tensioned. Since it is specified that it can be used as a handbag under an exposed condition, there is an effect that the problems of the prior art described at the beginning can be remedied.

That is, according to the above construction of the present invention, the bag body (M) is made of a soft cloth material, and the upper surface (14) and the lower surface (15) thereof are substantially the same isosceles triangles as shown in FIGS. Not only does it also form both sides (13) of the bag body (M) as well.
In particular, it is formed into a substantially isosceles trapezoidal shape as shown in FIGS.

The short upper base portion of the isosceles trapezoid is continuous with the back surface (11) of the bag body (M), while the longer lower base portion is the abdominal surface (12) of the bag body (M). (1
Slide fasteners (19) for loading and unloading items are arranged along the longitudinal center line of 2) and the fasteners
A male and female eyelet or a buckle is formed on the mounting ear pieces (21) for the fastener, which are located at both ends of (19) and project from the apexes of the upper surface (14) and the lower surface (15) forming the above-mentioned isosceles triangle. A pair of fasteners (22) (23) are attached.

The abdominal surface (12) of the bag body (M) has a length (L) corresponding to the length difference between the lower base portion and the upper base portion forming the isosceles trapezoid of both side surfaces (13), and the back surface (11). ), The upper surface (14) and the lower surface (14) which are restored to an isosceles triangle as shown in FIG. Combined with 15), it has the effect of ensuring an extremely large capacity of the bag body (M),
By holding the backpack band (24) in that state,
This can be used as a handheld band.

Further, when the fastening metal fittings (22) and (23) are released from the locked state, the slide fastener (19) can be tensioned in a linear state as shown in FIG. In the bag body (M), the abdominal surface (12) formed from the long lower base portions of the both side surfaces (13) can be opened in its fully opened state. As a result, there is an effect that a large-sized item or a fixed item can be smoothly put in and taken out without any trouble.

Further, the fasteners (22) and (23) are the upper surface of the above-mentioned isosceles triangle.
(14) and the lower surface (15) are attached to the mounting ear pieces (21) projecting from the respective apexes, so that when the male and female pairs are locked to each other, they are attached to the upper surface (14) of the bag body (M). The bottom surface (15) is fourth
As shown in the figure, all of the vertices are bent inward and deformed flat, and the slide fastener (1
Since 9) is kept in a covered state, rainwater can be completely prevented from entering the bag body (M) not only when it is carried on its back but also when it is carried by hand.

Further, not only the upper surface (14) and the lower surface (15) of the bag body (M) form an isosceles triangle, but also both side surfaces (13) of the bag body (M) are formed into a substantially isosceles trapezoid. The abdominal surface (12) of the bag body (M) is the back surface by the length dimension (L) corresponding to the difference in length between the lower bottom side and the upper bottom side.
Since it is configured to project larger than (11), the upper surface of the bag body (M) when the fasteners (22) and (23) are locked.
Even if the (14) and the lower surface (15) are bent and deformed inwardly and flatly, there is no fear that the capacity of the bag body (M) is unnecessarily reduced.

In other words, even if the upper surface (14) and the lower surface (15) of the isosceles triangle are only slightly bent, the pair of male and female fasteners can be formed based on the protrusion of the length dimension (L). (22) and (23) can be locked, and in the case of the present invention, the mounting position of the shoulder strap (24) with respect to the bag body (M) does not change, and it is a flexible bag under the fixed state. Since the main body (M) is only deformed as described above and can be used both as a backpack type and a handheld type, it is different from the known device described at the beginning.

Moreover, since the fasteners (22) and (23) are embodied as eyelet hooks or plug-in type buckles, they can be engaged and disengaged under a so-called one-touch operation, and a troublesome binding operation like a cord. Even if the bag body (M) does not need to be added and the articles are excessively accommodated due to the flexibility of the bag body (M), the fastening metal fittings (22) (23) receive the internal pressure thereof.
There is no danger of accidentally leaving.

Further, in the case of the present invention, the pair of left and right shoulder straps (24) has the upper end of the upper surface (14) in relation to the upper surface (14) and the lower surface (15) of the bag body (M) forming an isosceles triangle. The band is attached centrally to the bisector close to the center, with a small gap between the left and right sides, while the lower end of the band (24) is also attached to the left and right ends of the lower surface (15). It is installed in a state of large distribution.

Therefore, the back surface of the body (M) of the bag (12), which is in contact with the back of the human body, can be carried by the back strap band (24) in a well-balanced and stable manner, and both back strap bands (24) can be carried. By having the same, it becomes possible to use the bag body (M) as a carrying band while also using it as a carrying band.

In addition, the upper end of the shoulder strap (24) is the bag body (M).
Since it is attached and fixed to the upper surface of the through the reinforcing seat (25), the upper end where weight is concentrated when using it on its back,
It can be strengthened by the reinforcing seat (25) to improve durability, and a hanging strap (28) is also attached and fixed to the upper end of the band (24). Top surface (1
Since it is located on the bisector of 4), the bag main body (M) that is not in use can be hung stably, and it is extremely convenient for its natural drying.
