Description

  The present invention relates to a school bag handle for school children.

  A school bag with a handle having a handle formed at the upper end of the school bag back plate is known. Since the school bag handle is used in various situations such as when the school bag is pulled out from a school locker or moved at a short distance, many school bags with a school bag handle have been sold in recent years.

  In recent years, school bags equipped with a reflective material that reflects light such as a head ride of a vehicle and makes a driver recognize the presence of a child have been sold.

  In Patent Document 1, both ends are attached to both sides of the upper end portion of the back plate (2) of the school bag body (1), and the whole is formed in an arch shape, and the upper part is upward from the school bag body (1). The handle (3) has a slender handle main body (3a) made of a flexible leather material folded in a U-shaped section, and the handle main body (3a). A reflective tape (3b) which is sandwiched and sewn on the opening edge of the U-shape and is folded in the same manner, and the folded portion is exposed over the entire length of the handle (3). A school bag handle is disclosed in which the reflective tape (3b) is exposed on the front side of the school bag body (1).

Utility Model Registration No. 3163257

However, the school bag of Patent Document 1 has the following problems.
(1) Since the leather material is folded back into a U-shaped cross section to form a handle body, a ridge is formed when the leather material is folded into an arch shape. Therefore, the appearance of the school bag is impaired, and there is a possibility that an unpleasant tactile sensation may be given when the handle main body is gripped.
(2) Since the leather material is folded into a U-shaped cross section to form a handle body, it is difficult to bend (high bending rigidity). Therefore, for example, when the school bag cover is mounted, it is necessary to mount the school bag cover while resisting the bending rigidity of the handle main body, which complicates the mounting operation. In addition, when the school bag is carried on the back, the main body of the handle may come into contact with the child's back head, shoulders, etc., giving a sense of discomfort.

  In order to solve the above problems, the present invention is (1) a handle having both ends attached to the back upper end of the school bag and projecting in an arch shape, the first leather material and the first leather material, Is a separate body, the second leather material sewn to the first leather material, and a core material sandwiched between the first leather material and the second leather material, And a reflecting material is disposed at a position facing the outside along the gap between the first and second leather materials.

  (2) In the above (1), the first leather material and / or the second leather material bulges in a direction away from the core material in the thickness direction of the handle. The listed school bag handle. According to the configuration of (2), the appearance of the school bag is improved by bulging the first leather material, and the gripping surface when gripping the handle is increased by bulging the second leather material. Since it becomes R, it becomes easier to hold.

  (3) The handle of the school bag according to (1) or (2) above, wherein the core member is provided over the entire length of the handle. According to the configuration of (3), the fixing strength with respect to the school bag of the handle can be improved.

  (4) The school bag handle according to any one of (1) to (3), wherein the reflector is provided on both left and right sides in the width direction of the handle. According to the configuration of (4), since the reflecting material is disposed on both sides in the width direction of the handle, light from more directions can be reflected.

  (5) The handle of the school bag according to any one of (1) to (4), wherein the reflector is provided at a position excluding both ends of the handle.

  (6) The school bag handle according to any one of (1) to (4), wherein the reflector is provided over the entire length of the handle.

  (7) The first leather material is bent so as to wrap the core material, and both the bent end portions extend toward the center in the width direction of the handle, and / Or the second leather material is bent so as to wrap the core material, and both the bent end portions extend toward the center in the width direction of the handle. The school bag handle according to any one of (1) to (6), which is characterized in that According to the structure of (7), since the number of layers which comprise a handle increases by folding a leather material, the rigidity of a handle can be improved.

  (8) The handle of the school bag according to any one of (1) to (6), wherein the first leather material and the second leather material have different leather thicknesses. According to the configuration of (8), one of the first leather material and the second leather material can be thick and the other can be thin, so that a handle according to the application can be designed. For example, the lower leather material is made thin and the core material is put in to improve comfort, and the upper leather material is made thick and the upper leather material is made coreless while maintaining rigidity at an acceptable level. can do.

  (9) The second leather material is disposed below the first leather material at the apex of the arch of the handle, and the second leather material is in a closed loop shape. The handle of the school bag according to any one of (1) to (8), wherein the handle is formed and a reinforcing tape is disposed in the closed loop. According to the structure of (9), since the intensity | strength of the leather material (namely, 2nd leather material) of the side hold | gripped with a finger | toe increases, it can make it difficult to produce problems, such as a leather elongating by the own weight of a school bag. .

  According to the present invention, the first leather material and the second leather material are stacked and used as a handle. It is difficult to wrinkle (when fixed to the school bag). Moreover, since it is easier to bend than a handle in which a leather material is bent into a U-shape, it is possible to prevent the work of attaching a school bag cover or the like from becoming complicated.

It is a rear view of a school bag. It is a top view of a handle. It is sectional drawing of a handle. It is sectional drawing of a handle (modification 1). It is sectional drawing of a handle (modification 2). It is sectional drawing of a handle (modification 2). It is sectional drawing of a handle (modification 3). It is sectional drawing of a handle (modification 3). It is sectional drawing of a handle (modification 4). It is sectional drawing of a handle (modification 5). It is a top view of a handle (modification 6).

  FIG. 1 is a rear view of a school bag with a handle attached according to an embodiment of the present invention. However, the shoulder belt is omitted from the illustration. With reference to the figure, the school bag 100 includes a backrest 10, a back can neck 20, a back can mounting portion 30, and a handle 40.

  The backrest 10 is a portion that comes into contact with the back of the child when the school bag 100 is carried on the back. Therefore, it is desirable to use a base material (for example, urethane) excellent in cushioning properties. Of the backrest 10, the area inside the dotted line displayed in U-shape is one step lower than the area outside the dotted line. Thereby, a passage for air is formed, and when the school bag 100 is carried on the back, heat hardly accumulates on the back.

  The back cane neck 20 is a loop-shaped metal fitting formed on the back upper end of the school bag 100. Space saving can be realized by suspending the school bag on the side of the desk using the back cannula 20.

  The back can mounting portion 30 is provided on each of the left and right sides of the back can neck 20, and a shoulder belt (not shown) is attached to the back can mounting portion 30 via the back can (not shown). Can do.

  Next, the handle 40 will be described in detail with reference to FIGS. FIG. 2 is a plan view of the handle (before attaching the school bag), and FIG. 3 is a cross-sectional view of the handle taken along the AA plane. The handle 40 is disposed at the upper end of the back surface of the school bag 100, and both end portions thereof are fixed to the school bag 100 by fastening devices 50. The handle 40 protrudes in an arch shape above the school bag 100, and the side surface (surface on which a reflective material described later) is provided in the front-rear direction of the school bag as it approaches the center (that is, the vertex of the arch) from both ends. It is twisted to face. That is, the handle 40 is gradually twisted from both ends along the apex of the arch, and twisted so that the direction of the side surface differs from the both ends by approximately 90 degrees at the top.

  The handle 40 includes a pair of upper and lower first leather material 41 and second leather material 42, a core material 43, and a reflection sheet (corresponding to a reflection material) 44. The first leather material 41 and the second leather material 42 are separate from each other, and are different from those obtained by folding a single leather material into a U-shape as described in Patent Document 1. Therefore, since the first leather material 41 and the second leather material 42 are separate from each other, the thicknesses of the first leather material 41 and the second leather material 42 can be made different from each other. In the present embodiment, the first leather material 41 is formed to be thicker than the second leather material 42, and the second leather material 42 is folded inward at both ends. A leather material bending portion 42a is formed. That is, the second leather material 42 is bent so as to wrap the core material 43, and the bent second leather material bent portion 42 a extends toward the center in the width direction of the handle 40. (In other words, it extends to the vicinity of the center). For convenience of explanation, a portion of the second leather material 42 other than the second leather material bending portion 42a may be referred to as a second leather material main body portion 42b.

  In this way, by bending the second leather material 42, a three-sheet structure in which the second leather material main body portion 42b, the core material 43, and the second leather material bending portion 42a are laminated is formed. Strength can be increased. Note that the first leather material 41 and the second leather material 42 can be turned upside down. That is, in FIG. 3, the second leather material 42 can be disposed on the upper side, and the first leather material 41 can be disposed on the lower side.

  In the present embodiment, since the first leather material 41 is formed thick, the core material 43 is disposed between the second leather material main body portion 42b and the second leather material bending portion 42a. Only (in other words, even if the first leather material 41 side is coreless), the required strength of the handle 40 can be satisfied.

  Between the 1st leather material 41 and the 2nd leather material bending part 42a, the reflective sheet 44 return | folded by the U shape is arrange | positioned. In other words, the reflection sheet 44 is sandwiched between the first leather material 41 and the second leather material bending portion 42 a, and outwards along the gap between the first leather material 41 and the second leather material 42. It is arranged at the position to face. In other words, the reflection sheet 44 is disposed at a position where at least a part of the reflection sheet 44 is visible from the outside of the school bag.

  Further, the reflection sheet 44 is disposed at a position excluding both end portions in the longitudinal direction of the handle 40. However, as will be described later, the reflection sheet 44 may be disposed over the entire length of the handle 40 in the longitudinal direction.

  As shown in FIG. 3, the reflection sheets 44 are respectively disposed on the left and right sides in the width direction of the handle 40. Therefore, light incident from more directions can be reflected. In the structure of patent document 1, since the reflective sheet is arrange | positioned only at the front side of the school bag, the light irradiated from the back side of the school bag cannot be reflected. Here, the school bag 100 may be used in a usage method different from the original usage method. For example, the direction of the school bag 100 is not necessarily constant, such as “one shoulder belt is put on the shoulder and the other shoulder belt is not put on the shoulder”, “the hand 40 is held and the school bag 100 is carried”. Accordingly, by disposing the reflection sheets 44 on both the left and right sides in the width direction of the handle 40 as in the present embodiment, it is possible to reflect light incident from more directions, so that safety can be improved.

  Although the material used for the reflective sheet 44 is not particularly limited, for example, a synthetic resin sheet kneaded with metal or glass particles can be used.

  The core material 43 is sandwiched between the first leather material 41 and the second leather material 42, and the first leather material 41 and the second leather material 42 are changed by changing the volume of the core material 43. The amount of swelling can be adjusted. In the illustrated example of FIG. 3, the second leather material 42 bulges greatly downward, and the first leather material 41 bulges small upward. In other words, the first leather material 41 and the second leather material 42 bulge in a direction away from the core material 43 in the thickness direction of the handle 40.

  In this manner, by bulging the second leather material 42 downward, the gripping surface when gripping the handle 40 becomes R, so that it is easy to hold. Moreover, the appearance of the school bag 100 can be improved by bulging the first leather material 41 upward. Only one of the first leather material 41 and the second leather material 42 may be bulged.

  Although the material used for the core material 43 is not specifically limited, For example, urethane can be used. The core material 43 is provided over substantially the entire length of the handle 40. Accordingly, the fastening device 50 penetrates the first leather material 41, the second leather material 42, and the core material 43 and is attached to the school bag 100, so that the fixing strength of the handle 40 to the school bag 100 is increased. Can do.

  Here, in the case of a handle having a conventional structure in which a leather material is bent into a U-shape, the core material is disposed only in the grip portion that avoids both ends of the handle, so that the rigidity of the fixed portion is increased by the core material. I can't. That is, the handle having a conventional structure cannot be inserted into the fixed portion because the core is thick. For this reason, the structure of the fixing part is fragile, and it is necessary to withstand the weight of the school bag only with leather material. On the other hand, in this embodiment, since the core material 43 is arrange | positioned over the substantially full length of the handle 40, the fixing strength with respect to the school bag 100 of the handle 40 can be raised with respect to a conventional structure. .

  The first leather material 41, the second leather material 42, the core material 43, and the reflection sheet 44 are sewn by seams indicated by dotted lines, and the reflection sheet 44 is composed of the first leather material 41 and the second leather material. 42. In Patent Document 1, the handle is difficult to bend because the reflection sheet is sandwiched and sewn to the opening end of the leather material folded in a U-shape.

  On the other hand, in the present embodiment, the first leather material 41 and the second leather material 42 separated from each other are overlapped to sandwich the reflection sheet 44, so that the handle 40 is easy to bend. Therefore, when the school bag cover is mounted, the handle 40 can be easily bent, so that the mounting operation can be easily performed.

  In addition, since the handle 40 is less likely to wrinkle than the configuration of Patent Document 1, the appearance is improved, and an unpleasant tactile sensation when the handle 40 is gripped can be reduced.

(Modification 1)
The reflection sheet 44 of the present invention may be disposed at a position facing the outside along the gap between the first leather material 41 and the second leather material 42, and is limited to the configuration of the above-described embodiment. It is not a thing. For example, as illustrated in FIG. 4, a reflection sheet 44 that is not folded may be sandwiched between the first leather material 41 and the second leather material 42.

(Modification 2)
As described above, the amount of swelling of the handle 40 can be changed by changing the filling amount of the core material 43. Therefore, for example, the filling amount of the core material 43 is reduced with respect to the handle 40 of FIG. 3 and the configuration shown in FIG. 5 is changed, or the filling of the core material 43 is filled with respect to the handle 40 of FIG. The amount can be reduced to the configuration shown in FIG.

(Modification 3)
The form of the 1st leather material 41 and the 2nd leather material 42 is not limited to the above-mentioned form. For example, as shown in FIGS. 7 and 8, if the cost is acceptable, both the first leather material 41 and the second leather material 42 can be made thin and bent. In this case, the core material 43 is disposed between the main body portion and the bent portion of the first leather material 41 and the second leather material 42. Thereby, the grip of the handle 40 can be further enhanced, and the rigidity can be increased by increasing the number of layers constituting the handle 40.

(Modification 4)
The reflective material may be changed to the structure shown in FIG. Referring to the figure, the reflective material of this modification is a thin plate-like core member 45, a fine core member 46 provided at the outer end of this thin plate-like core member 45, and a U core with the fine core member 46 as a turning point. The reflection unit includes a reflection sheet 44 bent in a letter shape. This reflection unit is sandwiched between the first leather material 41 and the second leather material 42, and the first leather material 41, the reflection sheet 44, the thin plate core material 45, and the second leather material 42 overlap each other. The reflective function is mounted on the handle 40 by sewing.

(Modification 5)
You may change the handle 40 into the structure shown in sectional drawing of FIG. The first leather material 41 and the second leather material 42 of Modification 5 have a closed loop structure (that is, a one-turn winding structure) in which folded portions are joined. A core material 43 is sandwiched between the first leather material 41 and the second leather material 42. Further, a reflection unit is arranged as in the fourth modification. Further, as a characteristic configuration of this modification, a reinforcing tape accommodating portion 42c is formed in a closed loop of the second leather material 42, and a reinforcing tape 47 is disposed in the reinforcing tape accommodating portion 42c.

  According to this modification, the strength of the leather material on the side gripped by the finger (that is, the second leather material 42) is increased, so that problems such as leather stretching due to the weight of the school bag 100 can be made difficult to occur. .

(Modification 6)
In the above-described embodiment, the reflective sheet 44 is formed at a position avoiding both ends of the handle 40, but the present invention is not limited to this, and as shown in FIG. A reflective sheet 44 may be provided.
