JP 2004-357766 A

  An object of the present invention is to provide a school bag that can easily adjust the depth of the sub-accommodating portion without opening the lid.

  The school bag of the present invention (Claim 1) is provided with a take-out port at the top of the main storage and the sub-accommodation located in front of the main storage and covers the front from the top of the main storage and the sub-storage with a lid. In the school bag, the sub-accommodating part is characterized in that a widening means for widening the part is provided on the side part.

  It is preferable that the sub-accommodating part is provided with a widening means for continuously widening the part to the upper end on the side part (Claim 2). Further, it is preferable that a connecting belt for connecting the lid to the bottom of the main storage portion is attached to the lid so as to be movable up and down (Claim 3).

  Further, the widening means is provided with a main hook provided with a cut portion capable of separating and joining the hook of the sub-accommodating section in the width direction, and an auxiliary hook formed by sewing the peripheral edge to the inner surface side of the main hook. And an opening / closing member for separating and joining the cut portion provided in the cut portion is more preferable. In that case, it is preferable that the said cut | interruption part is provided continuously from the upper end of the side part of the said main board to a lower end (Claim 5). The opening / closing member is preferably a slide fastener. It is preferable that the auxiliary bag is formed of a cloth having a design different from that of the main bag. Further, it is preferable that the slide fastener has an upper end separated when the slider is below and closes as the slider is raised (claim 8).

The school bag is provided with a take-out port at the top of the main storage part and the sub-accommodation part located in front of the main storage part, and the front is covered with a lid from the top of the main storage part and the sub-accommodation part. The part is out. In the school bag of the present invention (Claim 1), a widening means for widening the side portion is provided on the side portion of the sub-accommodating portion, and the widening means goes out. Therefore, in order to adjust the depth of the depth of the side part of the sub-accommodating part, unlike the conventional school bag, there is no need to bother to open the lid. Therefore, it can be easily adjusted.

  When the sub-accommodating portion is provided with widening means for continuously widening the portion to the upper end on the side portion (Claim 2), the side portion is not covered with the lid, and is in an outing state. Therefore, a widening means for continuously widening the side portion is also out. Therefore, it is possible to easily adjust the depth of the depth of the side portion of the sub storage portion.

  When the connecting belt for connecting the lid to the bottom of the main storage portion is attached to the lid so as to be able to be raised and lowered (Claim 3), the length of the connecting belt coming out from the lower end of the lid can be adjusted. ing. Therefore, even if the side part of the sub storage part is widened or the side part is widened, the connecting belt becomes long and can be connected to the bottom part of the main storage part.

  The widening means is a main hook provided with a cut portion capable of separating and joining the hook of the sub-accommodating section in the width direction, and an auxiliary hook formed by sewing the peripheral edge to the inner surface side of the main hook, When the opening / closing member for separating / joining the cut portion provided in the cut portion is provided (Claim 4), since the open / close member is provided in the cut portion, the main bag can be opened and closed freely. ing. Accordingly, when the cut portion of the main basket is opened to the left and right, the auxiliary rod is exposed during that time, so that the depth of the auxiliary storage portion can be deepened. Moreover, when this cut | interruption part is closed, since an auxiliary paddle is accommodated in the inner surface of a main wall, the depth of the sub-accommodation part can be made shallow while returning to the original. In other words, the depth of the sub-accommodating section can be easily adjusted by simply opening and closing the main shell that is out of the lid.

  When the cut portion is provided continuously from the upper end to the lower end of the side portion of the main shell (Claim 5), the cut portion is directly connected to the take-out port. Therefore, when the sub-accommodating portion opens the cut portion, the side portion of the sub-accommodating portion is widened and the depth of the outlet is deepened. As a result, the capacity of the sub-accommodating portion is increased and it is easy to put in and take out objects.

  When the opening / closing member is a slide fastener (Claim 6), the slide fastener can adjust the coupling position of the elements steplessly. Therefore, the depth of the sub-accommodating portion can be adjusted according to the coupling position of the elements of the slide fastener.

  When the auxiliary bag is formed of a cloth having a different design from that of the main bag (Claim 7), the auxiliary storage portion exhibits a different appearance due to the appearance of the auxiliary bag.

It is a perspective view in the state where a part notched showing the reference example of the school bag of the present invention was carried out. 2A is a right side view of a reference example of the school bag of FIG. 1, FIG. 2B is a left side view thereof, and FIG. 2C is a bottom view thereof. It is a structure explanatory drawing of the bag of the sub-accommodation part of the school bag of FIG. 4A is a left side view of the main part of the satchel of FIG. 1 with the slide fastener opened, and FIG. 4B is a bottom view of the main part of FIG. 4A. 5 is a cross-sectional view taken along line AA in FIG. It is a principal part perspective view which shows the other reference example of the school bag of this invention. 7a and 7b are explanatory diagrams of FIG. It is explanatory drawing of the side surface which shows the other reference example of the school bag of this invention. It is explanatory drawing of the side surface which shows one Embodiment of the school bag of this invention.

  As is often seen in the school bag 1 shown in FIG. 1, the storage unit includes a main storage unit 2, a sub storage unit 3 positioned in the front stage, and an auxiliary storage unit 4 positioned in the front stage. The entire top of the sub-accommodating unit 3 is a take-out port 5. Further, the side portion 3 a and the bottom portion 3 b are formed by a flange 6. A cover 12 covers the top of the main storage 2 and the front of the auxiliary storage 4. In addition, the top part of the main storage part 2 is also the entire outlet 2a. This will be described in detail below.

  As shown in FIG. 1, the lid 12 of the school bag 1 has this base end attached to the back plate 13. A Y-shaped belt 14 is attached to the tip side. As shown in FIG. 2 c, a male member 15 b that can be engaged and disengaged with a female member 15 a of a lock 15 provided on the bottom surface of the main storage portion 2 of the school bag 1 is attached to the tip of the Y-shaped belt 14. Yes. The lock 15 is generally used as a school bag lock. A recess is formed in the female member 15a, and a protrusion-like latching portion 16a that can rotate is provided in the recess. The male member 15b is provided with 2 to 3 hooking holes 16b that can be engaged with and disengaged from the hooking portion 16a. The male and female members prevent the male and female members from being pulled out by rotating the latching portion 16a from the upper surface of the hole 16b engaged with the latching portion 16a.

  When the hole 16b located on the distal end side of the male member 15b is locked to the latching portion 16a and locked, the lid 12 projects outwardly as shown by a two-dot chain line shown in FIG. A large space S is formed between them. The depth of the space S is a depth that allows the flange 6 of the sub-accommodating portion 3 described later to be widened. In this embodiment, it is assumed that the ridge width of the ridge 6 of the sub-accommodating portion 3 is widened to about 1.5 to 2.5 times before widening. The lock is not limited to the structure described above. A lock that allows a large space S is more preferable because the depth of the sub-accommodating portion can be further deepened.

  Also, for example, an adjuster mechanism is provided to allow the locking portion to be extended freely so that the cover lid can be securely closed and engaged even when the amount of storage or size is stored to some extent. (See JP 2004-357766). Moreover, you may attach a Y-shaped belt to a lid | cover via an elastic member.

  As described above, the top portion of the sub-accommodating portion 3 is an open outlet, and the side portion 3a and the bottom portion 3b are formed by the flanges 6. As shown in FIG. 1 and FIG. 3, the rod 6 includes a main rod 7 and an auxiliary rod 8 provided on the inner surface side of the main rod and wider than the width of the main rod 7. Yes.

  The main bag 7 is made of a leather material having a tenacity and a synthetic leather material, and as shown by a two-dot chain line in FIG. 3, a narrow rectangular sheet is bent into a concave shape so that the side portion 7a and the bottom portion 7b are formed. Forming. In addition, a concave cut portion 9 is formed in the entire lower portion of the side portion 7a and the bottom portion 7b, leaving the vicinity of the upper ends on both sides of the side portion 7a. The cut portion 9 is provided with one slide fastener 10 for separating and joining the main rod 7 back and forth (see FIGS. 2a to 2c). By separating the elements of the slide fastener 10, the side portion 7a and the bottom portion 7b of the main bag 7 are separated. As shown in FIG. 3, the front separating portion 7c can be slightly rotated to the lid side 12 with the upper end portion of the main basket 7 or the slider stop portion of the slide fastener 10 as a fulcrum (see FIG. 4a). Then, as shown in FIGS. 3 and 4a, by rotating, the side portion 7a has a width so that the front side separating portion 7c and the rear side separating portion 7d are opened to form opposite sides of an isosceles triangle. Spread. As shown in FIGS. 3 and 4b, the bottom portion 7b is widened so as to form a rectangular opposing side (long side) by the front separating portion 7c and the rear separating portion 7d.

Note that two sliders may be provided on the one slide fastener 10 so as to face each other. In this case, the separation / joining position of the cut portion 9 of the main rod 7 can be freely adjusted by two sliders. For example, the coupling position of elements can be freely determined such that the coupling of elements is bilaterally symmetric, or only one of the left and right is coupled.

  As shown in FIG. 3, the auxiliary hook 8 is formed by bending a piece of leather or synthetic leather having the same tension as that of the main hook 7 into a concave shape to form a side portion 8a and a bottom portion 8b. The bottom portion 8b is formed in a rectangular shape, and the width of the collar is about 1.5 to 2.5 times the collar width D of the main collar 7 to which the slide fastener 10 is coupled. The side portion 8a is formed in a substantially isosceles triangular shape having a lower side having the same length as the ridge width. As shown in FIGS. 3 and 4 a and b, the auxiliary scissors 8 and the main scissors 7 are stitched together with their peripheral edges overlapped to form a scissors 6.

  As shown in FIG. 4, when the slide fastener 10 is opened and the main rod 7 is separated in the front-rear direction, a surface is formed by the inner auxiliary rod 8 during the separation. Moreover, the side part 6a of the collar 6 of the sub-accommodating part 3 is formed in a substantially isosceles triangle, and the bottom part 6b is formed in a wide rectangle. Thus, the sub-accommodating unit 3 can accommodate a large-sized object having a large thickness because the depth of the ridge 6 is expanded as a whole. On the other hand, the depth of the outlet 5 is shallower than the depth of the storage portion as shown in FIG. 4a. Therefore, the stored item stored in the sub-accommodating portion is prevented from popping out from the extraction port because the extraction port 5 is narrow.

  The auxiliary rod 8 is reinforced because the vicinity of the peripheral edge overlaps with the front separating portion 7c and the rear separating portion 7d. Therefore, even if the sub-accommodating unit 3 accommodates a large object or a heavy object, the sub-accommodating part 3 can maintain a lustrous appearance without being easily deformed.

  The sub-accommodating section 3 can be easily changed from a wide to a narrow ridge as shown in FIG. 1 simply by coupling the entire slide fastener of FIG. Further, since the auxiliary rod 8 is located on the back side of the main rod 7, it is not seen at all and does not appear so that it is not complicated. The scissors 6 are sturdy because they have a double structure with the main scissors 7 and the auxiliary scissors 8.

  As shown in FIG. 5, the auxiliary rod 8 is formed with a single knob 20 at the center inside the side portion 8 a and the bottom portion 8 b, and with a folding rod 21 that is bent inward at the intersection. It is preferable. By providing the knob 20 and the folding bar 21, the auxiliary bar 8 is generally biased inward, so that the slide fastener 10 is prevented from being damaged by the slider. Further, the storage in the sub storage unit 3 is facilitated. In this embodiment, as described above, the material of the auxiliary rod 8 is a material having elasticity, but may be a flexible material that can be easily accommodated in the sub-accommodating unit 3.

  As shown in FIG. 4 a, it is preferable that the cloth of the auxiliary basket 8 is provided with a pattern 25. For example, it is preferable to employ a fabric having a design different from that of the main basket 7 such as a character or a check pattern. The bag 6 of the sub-accommodating portion 3 is interesting because the slide fastener elements are separated and widened to reveal a design that did not exist before widening. In addition, the auxiliary basket may be a plain or the same color as the main basket.

As another reference example, as shown by a two-dot chain line in FIG. 6, a slide fastener 10 in FIG. 1 is provided so that both sides thereof protrude from the upper end of the main bag 7. In this case, as shown in FIG. 7a, the main basket 7 is entirely separable. As shown in FIG. 7 a, the main basket 7 and the auxiliary basket 8 of this embodiment both form a rectangular fabric and form a side portion and a bottom portion. The width of the auxiliary rod 8 is preferably about 1.5 to 2.5 times the width of the main rod 7. However, if the school bag lid (see FIG. 1) can be locked, it may be wider. As in the above-described reference example, the auxiliary rod 8 is provided with a single picked portion at the center portion inside the side portion and the bottom portion, and a folding fold that is bent inward is attached to the crossing portion. , The whole is biased inward. The main rod 7 and the auxiliary rod 8 are stitched together by overlapping their peripheral edges to form the rod 6. The slide fastener 10 is provided with two sliders in a state of facing left and right. However, it may be one. As shown in FIG. 6b, the length of the portion 10a in which the slide fastener 10 protrudes from the upper end of the main rod is such that when the element of the portion is completely separated and opened to the left and right, as shown in FIG. The length can be fully expanded. As shown in FIG. 6, the protruding portion of the slide fastener may be fastened inside the sub-accommodating portion 3.

  Thus, as shown in FIG. 7a, when the slide fastener 10 is fully opened, the saddle 6 of the sub-accommodating portion 3 is divided into the main saddle 7 in the front and the back, and the auxiliary rod 8 is exposed and becomes wider from that time. In addition, the entire bag 6 of the sub-accommodating portion 3 is evenly expanded, and the depth of the take-out port 5 is widened and opened wide, so that it is easy to put in and out the object. If the slider provided on the slide fastener 10 in the left-right facing state is lowered as shown in FIG. 7b, the depth of the take-out port 5 becomes shallow, so that large items stored therein are prevented from jumping out from the take-out port. The

  Furthermore, as another reference example, as shown in FIG. 8, there is one in which the mounting position of the slide fastener 10 provided on the main bag of FIG. 1 is moved closer to the main storage portion 2. The length of the slide fastener 10 may not protrude from the upper end of the side portion as shown by the solid line, or protrudes from the upper end of the main shell as shown in FIG. May be adjustable.

  The school bag according to the embodiment of the present invention has the same structure except for the structure of the secondary storage part of the school bag of the previous reference example. The secondary storage part 3 has a top part as shown in FIG. And the whole surface is open. The side part 7a and the bottom part 7b are formed by a flange 6. The kite 6 includes a main kite 7 and an auxiliary kite 8. The main bag 7 is made of a leather material having a tenacity or a synthetic leather material, and a rectangular sheet is bent into a concave shape to form a side portion 7a and a bottom portion 7b. In the center of the left and right side portions 7a, a cut portion 9 is formed below the upper end of each side portion 7a. The left and right cut portions 9 are each provided with one slide fastener 10 that separates and joins the side portion 7a of the main rod 7 back and forth. The slider of the slide fastener 10 is pulled up to the upper end of the side portion 7a. Thus, the element is completely connected and the cut portion 9 is connected, and by pulling down the element, the element is separated and the cut portion 9 is separated.

  As shown in FIG. 9, in the completely separated state, the front separating portion 7c can be slightly rotated to the lid side 12 with the stop portion of the slider of the slide fastener 10 as a fulcrum. Then, by rotating, the width of the upper end of the side part 7a is widened so that the front side separating part 7c and the rear side separating part 7d are opened to form opposite sides of an inverted isosceles triangle. . That is, the depth of the outlet 5 can be deepened.

  The auxiliary rod 8 is formed of a single leather or synthetic leather having the same tension as the main rod 7 in a vertically long trapezoidal shape. The auxiliary rod 8 has its trapezoidal base, that is, a wide side aligned with the upper end of the main rod 7, the peripheral edge of the other side is along the cut portion 9, and is sewn to the inner surface side of the main rod 7.

  As shown in FIG. 9, when the slide fastener 10 is opened and the main rod 7 is separated in the front-rear direction, a surface is formed by the inner auxiliary rod 8 during the separation. Further, the side portion 6a of the ridge 6 of the sub-accommodating portion 3 is formed with a wide upper end and a narrow width toward the bottom. Thus, the sub-accommodating unit 3 can accommodate a large-sized object having a large thickness because the depth of the ridge 6 is expanded as a whole. On the other hand, since the depth of the take-out port 5 is widened, it becomes easy to put in and take out objects.

The lid in this embodiment is also provided with a Y-shaped belt and a male member (not shown) as in the above-described reference example. The male member can be engaged with and disengaged from the lock female member provided on the bottom surface of the main storage portion. Furthermore, as described above, the length of the Y-shaped belt can be adjusted by providing an adjuster mechanism or an elastic member.

  Furthermore, as another embodiment (not shown), the tape portion of the slide fastener may be used instead of the main bag. In this case, the peripheral edge of the tape part and the peripheral edge of the auxiliary hook are stitched together to form the hook of the auxiliary storage part. This main bag is not made of leather or synthetic leather as in the above-described embodiment, and uses the tape that is the base of the element, so that it is effective in reducing the weight and economy of the school bag. Furthermore, since there is no complicated work of forming a cut portion on the main board and attaching the slide fastener as in the above embodiment, the work efficiency is also increased. In addition, the tape of a slide fastener has tension property and a wide thing is good. The shape of the auxiliary rod is the same as in the above embodiment.

  Further, instead of the slide fastener of the embodiment, a pair of magnetic members having different magnetic poles may be provided on the right side and the left side of the cut portion, respectively. The magnetic member formed in small pieces may be partially provided in the cut portion, or may be provided in the entire concave frame cut portion.

  Moreover, you may provide the fastening member for hold | maintaining a closed state in the required part of a notch part on both sides of a notch part, without providing a slide fastener or a magnetic member. In addition, you may provide this fastening member in the both sides which provided the magnetic member of the said embodiment.
