  However, since the shoulder belt has an integral structure with the back body, it is impossible to remove and use it alone. Further, since the shoulder belt has an integral structure with the back, the manufacturing cost is higher than the case where only the shoulder belt is manufactured as a single body.

  In order to solve the problem, it is desirable that the shoulder belt is not an integral structure with the back, and the shoulder belt can be used alone. However, at present, the shoulder belt (hereinafter referred to as a shoulder belt) is attached to the bag, and a shoulder belt having a function of being capable of being stored and having excellent workability as disclosed in Patent Document 1 is used alone. It is difficult to buy at.

  Accordingly, an object of the present invention is to provide a shoulder belt (also referred to as a shoulder strap) that can be easily attached / detached, easily adjusts the length of the belt, and can be stored when not in use, and a bag using the same. To do.

The present invention for solving the above problems includes a belt, a reel member having a reel that can be wound or pulled out from one end thereof, a reel support member that rotatably supports the reel, and a back. In order to connect to the provided connecting portion, the connecting member attached to the reel supporting member is provided as two sets, and the two sets are connected at the other end side of each belt, and the two reels A length adjusting mechanism for adjusting the length of each belt between the members , the length adjusting mechanism comprising: an outer frame having a thickness that is a multiple of the thickness of the belt; Formed on opposite sides of the frame body is a belt outlet provided in such a size that each belt can pass from the other end side, and a rectangular shape having a narrower width than the outer frame body. The other end is rotatably supported in parallel inside And a two piece capable back winding or winding each belt from, by the rotation of the two frames, a shoulder belt to adjust the length of the respective belt.

Moreover, another invention other than the above is a bag in which connecting portions for attaching the shoulder belt are provided at two locations on the upper surface or the side surface. This includes a belt, a reel member that can be wound or pulled out from one end side thereof, a reel member that has a reel support member that rotatably supports the reel, and the connecting portion to connect the reel member. Two sets of connecting members attached to the reel support member are provided as one set, the two sets are connected at the other end of each belt, and the length of each belt between the two reel members is adjusted. A length adjusting mechanism for the belt, and the length adjusting mechanism includes an outer frame having a thickness that is a multiple of the thickness of the belt, and each belt on the opposite side of the outer frame. A belt pull-out opening provided in a size that can be passed from the end side, and a rectangular shape having a narrower width than the outer frame body, are rotatably supported in parallel by the outer frame body on the inside, and the other Each belt can be wound or rewound from the end side One of a piece, by the rotation of the two frames, said a back which established the shoulder belt to adjust the length of each belt.

  The material, strength, and the like of the belt are appropriately selected according to the use and function of the bag in which the shoulder belt is used. For example, when the baggage accommodated in the bag is sufficiently heavy, it is necessary to have enough strength to support it, that is, sufficient tensile strength in the length direction, such as nylon 6, nylon 6, 6, etc. Various synthetic fibers such as polyamide fiber, polyester fiber, polyethylene fiber, and acrylic fiber can be used. Moreover, in order to improve tensile strength, inorganic fillers, such as glass fiber, can also be mix | blended. In addition, when the load resistance required for the shoulder belt is not so large, the shoulder belt can be formed using other fibers or leathers without being limited by the tensile strength.

  In addition, the belt used in the present invention must have a shape that can be wound around the reel. Therefore, the belt is preferably formed in a belt shape. Furthermore, it is desirable that the belt be formed in consideration of the design effect regardless of whether or not the tensile strength is required.

  For example, when using an existing handle without using the belt, it is desirable to wind the excess belt around the reel. For this purpose, it is necessary to provide a winding mechanism for the belt driven by elasticity in the reel member. With the elastic energy accumulated by the belt drawing operation, the excess belt can be wound up in the reel.

  In the present invention, the belt can be freely wound or pulled out from the reel. That is, if the belt can be freely wound or pulled out into the reel, for example, when the belt is pulled out, the belt is gripped and lifted, and when the belt is wound up, the belt is gripped. By separating the belt, the shoulder belt that can immediately wind the belt into the reel is realized.

  Also, the reel member needs to be formed in consideration of the weight of the luggage accommodated in the bag in which the shoulder belt is used, like the belt. That is, since the reel member also needs to have sufficient strength to support the load in the bag, the material (metal, plastic, etc.) and structure forming the reel member must be appropriately selected and designed. Note that a design such as a brand name, a logo mark, or other figures can be appropriately applied to the outer surface of the reel member from the viewpoint of improving decorativeness.

  In order to easily connect the shoulder belt to the back, it is desirable to provide a connecting member that can be detachably connected to the connecting portion of the back. The connecting member may be provided on the reel member.

  According to the present invention, a belt, a reel capable of winding or unwinding the belt from one end side of the belt between the reel members, and a piece capable of winding or unwinding the belt from the other end side are combined into two sets. By providing the combination, the belt can be easily adjusted to a desired length. Further, by providing a connecting member such as an insulator ring on the reel member, it can be detachably connected to, for example, a ring-shaped or D-shaped connecting portion provided on the back.

  Therefore, by using the shoulder belt of the present invention, the belt can be wound or pulled out using the reel member, and the belt can be adjusted to a desired length by winding or unwinding the belt using the piece. Therefore, for example, it can be used by hanging on a shoulder.

  Further, if the shoulder belt is removed from the connecting portion of the bag, it can be stored in an extra space or a pocket in the bag. Furthermore, since the shoulder belt can be handled as a single product or as a product attached to the bag, the number of sales and its form can be planned in accordance with customer demands and market trends.

  Hereinafter, an embodiment of a shoulder belt according to the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a perspective view showing a configuration of a shoulder belt according to an embodiment of the present invention. FIG. 2 is a partially enlarged view illustrating the shoulder belt length adjusting operation according to the embodiment of FIG.

  First, the configuration of the shoulder belt according to the present invention will be described. As shown in FIG. 1, the shoulder belt 100 includes belts 110 and 110, reels 121 and 121 that can wind or pull out each belt 110 from one end side, and reel rotation shafts 122 and 122 of each reel 121. Reel members 120, 120 having reel support members 123, 123 rotatably supported as shafts, and connecting members 130, 130 attached to the respective reel support members 123 for connection to connecting portions provided on the back. A length adjusting mechanism 140 for connecting the two sets at the other end of each belt 110 and adjusting the length of each belt 110 between two reel members 120; It has.

  The length adjusting mechanism 140 has an outer frame body 141 having a thickness that is a multiple of the thickness of the belt 110, and a size that allows each belt 110 to pass through the opposite sides of the outer frame body 141 from the other end side. The belt outlets 142 and 142 provided and a rectangular shape with a width narrower than the outer frame body 141 (a dimension in a direction perpendicular to the belt 110 in FIG. 1) are rotated in parallel by the outer frame body 141 inside. Two pieces 143 and 143 that are supported so as to be able to wind or rewind each belt 110 from the other end side are provided. At this time, each belt 110 is installed by bonding or sewing to the two pieces 143 and 143.

  The thickness of the outer frame body 141 is set to be a plurality of times the thickness of the belt 110 because when the belts 110 are wound by the rotation of the two pieces 143, the thickness of the wound belt 110 is wound. This is to prevent the thickness from exceeding the thickness of the outer frame 141.

  Next, the belt length adjustment operation of the shoulder belt according to the present invention will be described with reference to FIGS. 2 is an enlarged view of a portion surrounded by a long and short dashed line in FIG. The shoulder belt includes two reels 121 and pieces 143 shown in FIG. Each reel 121 can wind up or pull out all the belts 110. Each piece 143 can adjust the length of each belt 110 by winding or rewinding each belt 110 by rotation.

  Each reel 121 can be rotated using a conventionally known article or structure. For example, using a helical spring or rubber, each reel 121 can be rotated by these elasticity and each belt 110 can be taken up. On the other hand, by pulling out all the belts 110 and winding or rewinding them using the respective pieces 143, it is possible to adjust the length of each belt 110 arbitrarily. Since such a structure is frequently used in a tape measure or the like, detailed description thereof is omitted here.

  Adjustment of the length of the belt 110 using each piece 143 will be described with reference to FIG. As shown in FIG. 2, each belt 110 that has passed through each belt outlet 142 from each reel 121 is wound or unwound by rotation of each piece 143 around the imaginary line AA ′, and the length is reduced. Can be adjusted. The length of each belt 110 between the reel members 120 can be finely adjusted by setting the winding width of each piece 143 parallel to the virtual line BB ′ to 5 cm, for example. Of course, the length of only one of the belts 110 may be adjusted.

  After the adjustment of the length of each belt 110 is completed, the length of each belt 110 adjusted by the length adjustment mechanism 140 can be fixed so as to cover the length adjustment mechanism 140 as shown in FIG. The shoulder rest 230 may be installed, and the length adjusting mechanism 140 may be secured by a shoulder rest fixing member 231 such as a surface fastener.

  The length adjusting mechanism 140 including each belt 110 is fixed without rotating by the piece 143 being sandwiched between shoulder pads 230 from the front and back sides. A state in which a desired length of each belt 110 is fixed without changing the length of each belt 110 adjusted even when it comes into contact with the body or the like, and without causing any physical damage by direct contact with the length adjusting mechanism 140. The shoulder belt 100 can be used while maintaining the above.

  Next, another embodiment of the shoulder belt according to the present invention will be described with reference to FIGS. 3, 4, 5 (a), 5 (b), and 6.

  As a second embodiment, a shoulder belt capable of fixing a state in which the length of each belt is adjusted by a length adjusting mechanism will be described. As shown in FIG. 3, the shoulder belt 100 is installed between the two pieces 143 at the center of the outer frame 141 in order to prevent the two pieces 143 from rotating in addition to the configuration described above. By providing the belt fastener 150, a desired length of each belt 110 can be fixed.

  After each belt 110 is wound up and adjusted to a desired length by the rotation of each winding piece 143, the belt fastener 150 has an axis orthogonal to the imaginary line CC ′ around the belt fastener rotating shaft 151. Rotate 90 ° to the center to obtain the state shown in FIG. Thus, the length adjustment mechanism 140 can fix the state in which the length of each belt 110 is adjusted.

  As a third embodiment, an example of a shoulder belt provided with a length adjustment mechanism different from the configuration of the length adjustment mechanism described above will be given. As shown in FIG. 5A, the shoulder belt 100 includes a ring member 161 for connecting the belts 110 to each other by folding the other end of each belt 110 through a belt insertion hole 162, and a ring member 161. For each belt 110 between the reel members 120, the other end of each folded belt 110 is fixed with each belt clasp 165 of each buckle body 164, and each belt 110 is fixed to two belts of each buckle body 164. A length adjusting mechanism 140 is provided that returns the passage hole 163 from different directions (one on the paper surface in FIG. 5B is returned from the lower side and the other is returned from the upper side).
