JP6312291B2 - Strap and shoulder bag and rucksack to which the strap is attached - Google Patents

Description

  The present invention relates to a strap that can be adjusted in length, and more particularly, to a strap that is superior in length adjusting function to a strap previously invented by the inventor, a shoulder bag to which the strap is attached, and a rucksack.

  As a strap for a shoulder bag, by providing a thickness at the tip of a shoulder strap (referred to as an adjustment belt in Patent Document 1), the shoulder strap does not come off from a length adjusting device (referred to as Kokikan in Patent Document 1). What has been proposed is proposed (for example, see Patent Document 1). With this strap, you can shorten the strap by holding the shoulder bag and holding it lightly while holding the shoulder bag and grasping the tip of the shoulder strap with the opposite hand and pulling it to an appropriate length. In addition, the strap can be lengthened by holding the shoulder bag lightly and lifting the length adjusting device with the opposite hand.

  As another strap for a shoulder bag, an operation piece for pulling out a shoulder strap (referred to as a strap body in Patent Document 2) from an insertion port of a length adjusting device (referred to as Koki in Patent Document 2) is one end side of the shoulder strap. A device that can adjust the length of the strap with one hand has been proposed (see, for example, Patent Document 2). With this strap, while holding the handle of the bag with one hand, grasping the operation piece with the other hand and pulling the operation piece away from the bag, the strap can be contracted, or more correctly, the strap can be folded. . While holding the handle of the bag with one hand, grasp the operating piece with the other hand, pull the operating piece away from the bag to disengage the hook-and-loop fastener, and pull the shoulder strap out of the foot to extend the strap. It can be in a state where the strap is unfolded, or more correctly, the strap is unfolded.

  As a strap for the camera, the shoulder strap attached to the third support portion of the connection portion is passed through the adjuster and then passed through the second support portion of the connection portion, so that the length of the strap can be reduced. The thing which can change the length is proposed (for example, refer to Patent Document 3). In this strap, the lever part of the adjuster is operated, and the claw (claw) part of the adjuster is bitten into the shoulder strap, so that the length can be fixed.

  Patent Document 4 describes how to use a length adjusting device (referred to as Koki in Patent Document 4). According to Patent Document 4, it can be seen that both the invention described in Patent Document 4 and the prior art have one end of a shoulder strap (referred to as a belt in Patent Document 4) attached to the center shaft of the length adjusting device.

  Furthermore, as for the strap invented before by the inventor, the length of the strap can be adjusted by attaching one end of the shoulder strap to one side of the frame parallel to the central shaft and passing the other end of the shoulder strap through the central shaft. Have been proposed (see, for example, Patent Document 5). With this strap, you can adjust the length with one hand by sliding the footjob while holding the strap.

Utility Model Registration No. 3122623 (paragraphs 0006, 0010, 0012, FIG. 2) Japanese Patent Laying-Open No. 2009-165773 (paragraphs 0007, 0018, 0019, FIG. 3) JP 2009-39415 A (paragraphs 0033 and 0036, FIG. 3) Japanese Patent Laying-Open No. 2004-337276 (paragraphs 0002, 0003, FIGS. 1, 3, 4, 5, 6, 7) Japanese Patent Application No. 2012-146183 (paragraph 0015, FIG. 2)

  However, in the strap according to Patent Document 1, a thickness is provided at the tip of the shoulder strap so that the shoulder strap does not come off from the length adjusting device (hereinafter referred to as “job”). If you do not hold the shoulder bag lightly, the shoulder strap will be pulled into the footjob by the weight of the shoulder bag, and the strap will be too long. Also, when shortening the strap, if you do not hold the shoulder bag lightly, it will be difficult to pull the tip of the shoulder strap if the shoulder bag is heavy. On the other hand, when the shoulder bag is light, the shoulder bag is rotated by the momentum of pulling the tip of the shoulder strap. For example, as shown in Patent Document 1, the shoulder bag is held on the side (side). Will move in the direction of. As described above, in the strap according to Patent Document 1, both hands are blocked in order to adjust the length with the opposite hand while holding the shoulder bag lightly with one hand.

  In addition, in the strap according to Patent Document 1, the shoulder strap pulled out from the foot hangs down because the tip of the shoulder strap is grasped and pulled to an appropriate length. In particular, when the strap is adjusted to be short, the shoulder strap pulled out from the foot hangs down long, which is obstructive and poor in appearance.

  In the strap according to Patent Document 2, the operation piece for pulling out the shoulder strap from the foot is fixed to one end of the shoulder strap and the strap is folded, and the fixed operation piece is removed and the strap is expanded. Therefore, the length can be adjusted only in two stages.

  Further, in the strap according to Patent Document 2, both hands are blocked in order to adjust the length with the other hand while holding the handle of the bag with one hand.

  In the strap according to Patent Document 3, since the nail portion of the adjuster is engaged with the shoulder strap and locked, when the strap is released while the strap is hung on the neck, the strap is pulled by the weight of the camera. In other words, the shoulder straps come out and cannot be adjusted as expected. Therefore, the strap according to Patent Document 3 is not suitable for length adjustment in a state where the strap is hung on the neck.

  And, in the strap according to Patent Document 3, if the length of the strap is adjusted with the strap hung on the neck, the length of the shoulder strap is adjusted with the other hand while holding the camera with one hand. After that, the lever part of the adjuster must be operated and fixed to the length, and both hands are blocked.

  Further, in the strap according to Patent Document 3, an adjuster is required separately from the footjob in order to fix the length of the adjuster's claw to the shoulder strap. And since the adjuster is generally thicker than the foot, the strap becomes bulky.

  Furthermore, in the straps according to Patent Documents 1, 2, and 4, the shoulder strap is pulled out from the middle shaft of the foot so that the strap has a desired length, and then the shoulder strap is pulled to the middle shaft by pulling the tip of the shoulder strap. More precisely, the length is adjusted by bringing the shoulder strap into close contact with the shoulder strap attached to the central shaft. Therefore, when the front end portion of the shoulder strap is pulled, the shoulder strap is pulled into the foot by the weight of the bag, and the strap becomes longer than a desired length.

  In the strap according to Patent Document 5, when a new function of the strap is adjusted such that the length is adjusted with one hand while the trap is overhanging, it is desired to provide a strap with more excellent length adjustment function. I came to hear the request.

  Therefore, in the present invention, the above-described problems are solved, and in particular, the length adjustment function is superior to the strap previously invented by the inventor (the strap according to Patent Document 5; hereinafter also referred to as the previous invention). An object is to provide a strap, and a shoulder bag and a rucksack to which the strap is attached.

  In order to solve the above-mentioned problem, in the invention according to claim 1, a length adjusting device (hereinafter referred to as "job") comprising a shoulder strap, a frame body, and a central shaft disposed inside the frame body, Pass the strap that can be adjusted to the length of the ring body (hereinafter referred to as “Kokikan”) with the shoulder strap attached to the Kokikan through one side of the Kokikan frame parallel to the central axis, and then through the Kokikan. did. Then, after passing the shoulder strap passed through Kokikan through the center shaft of Kokikan, the other end of the shoulder strap was attached to another Kokikan or a suspended object.

  In the invention according to claim 2, the kokikan is configured to include a ring (wa) and a central shaft disposed inside the ring, and the shoulder strap attached to the kokikan ring is formed of the kokikan frame. After passing through one side parallel to the central axis, it passed through the central axis of Kokikan. Then, the shoulder strap passed through the center shaft of Kokikan was passed through the center shaft of Kokikan, and the other end of the shoulder strap was attached to another Kokikan or a suspended object.

  In the invention which concerns on Claim 3, the operation piece for operating a footjob was attached to one side facing one side of the frame which the shoulder strap passed.

  In the invention which concerns on Claim 4, the strap which is the invention which concerns on the said Claim 1 to the said Claim 3 was attached to the shoulder bag.

  In the invention which concerns on Claim 5, the strap which is the invention which concerns on the said Claim 1 to the said Claim 3 was attached to the rucksack.

  According to the first aspect of the present invention, the shoulder strap attached to the Kokikan is passed through one side parallel to the central axis of the Kokikan and then passed through the Kokikan, and the shoulder strap passed through the Kokikan is used as the central axis of the Kokikan. Since it passed, the shoulder strap can be tripled between Koki and Kokikan. Here, in the strap invented before by the inventor according to Patent Document 5, the shoulder strap overlaps twice, whereas in the invention according to claim 1, it can be tripled. Compared to the invention, the length adjustment function can be improved by a factor of about two.

  Thus, according to the first aspect of the present invention, the length adjustment function can be improved by a factor of about two compared to the previous invention, so that it is possible to deal with a wide range of height differences and physique differences. Therefore, a single strap can be used for a wide range of adult men, women, and children.

  In addition, according to the invention of claim 1, the length adjustment function can be improved by a factor of two compared to the previous invention, so this strap is shorter than the shoulder strap, for example, on the shoulder belt of a rucksack. It can also be applied.

  Furthermore, according to the first aspect of the invention, the length adjustment function can be improved by a factor of about two compared to the previous invention, so the strap length can be adjusted with a smaller amount of operation. Therefore, the length can be adjusted more quickly.

  According to the invention according to claim 2, the kokikan is configured to include a ring and a middle shaft disposed inside the ring, and the shoulder strap attached to the kokikan ring is formed of the middle shaft of the kokikan frame. Unlike the invention according to claim 1, the shoulder straps in Kokikan can be prevented from overlapping each other because they are passed through one side parallel to the center. Therefore, when adjusting the length of the strap, since there is no resistance that the shoulder straps rub against each other in Kokikan, the length can be adjusted with a lighter force than the invention according to claim 1. .

  According to the invention according to claim 3, since the operation piece for operating the footjob is attached to one side opposite to one side of the frame body through which the shoulder strap is passed, if the operation piece is grasped, Compared to this, it can be operated more easily. For this reason, the length of the strap can be adjusted with one hand while the strap is stuck.

  According to the invention according to claim 4, since the strap according to claims 1 to 3 is attached to the shoulder bag, the length of the strap can be adjusted with one hand while the strap is held over. Further, since the length of the strap is adjusted by sliding the footjob, it can be finely adjusted to a desired length steplessly. Also, the shoulder straps drawn from the footjob can be prevented from hanging down.

  Further, according to the invention of claim 4, since the length of the strap can be adjusted with one hand while the strap is overlaid, the strap is made long so that the shoulder bag can be easily overlaid. The strap can be shortened so that the shoulder bag is in close contact with the back. In this way, since the shoulder bag is in close contact with the body, the burden on the body can be reduced.

  In the conventional shoulder bag, since the strap is elongated so that the shoulder bag can be easily laid, the shoulder bag falls to the waist position. According to the invention of claim 4, the shoulder bag When the strap is shortened so that the shoulder bag is in close contact with the back, the shoulder bag can be raised to the position of the back, so that the appearance of the shoulder bag hanging can be made a good impression.

  Also, in the conventional shoulder bag, if the strap is shortened so that the shoulder bag is in close contact with the back, the contents of the shoulder bag cannot be taken out unless the shoulder bag is lowered. If the strap is lengthened while being hanged, the shoulder bag can be turned from the back to the belly, so that the contents of the shoulder bag can be taken out with the shoulder bag being laid.

  According to the invention of claim 5, since the strap of claims 1 to 3 is attached to the rucksack, the length of the strap can be adjusted with one hand while the rucksack is carried. Further, since the length of the strap is adjusted by sliding the footjob, it can be finely adjusted to a desired length steplessly. Also, the shoulder straps drawn from the footjob can be prevented from hanging down.

  According to the invention of claim 5, since the length of the strap can be adjusted with one hand while the rucksack is carried, the strap is lengthened so that the rucksack can be carried easily, and the rucksack is carried on the back. Therefore, the strap can be shortened so that the rucksack is in close contact with the back. If it does in this way, since the rucksack will stick to the body, the burden on the body can be reduced. And when lowering the rucksack, if the strap is lengthened, the rucksack can be easily lowered.

  In the conventional rucksack, since the strap is lengthened so that the rucksack can be easily carried on the back, the rucksack has fallen to the waist position. According to the invention according to claim 5, the rucksack is carried on the back. After that, if you shorten the strap so that the rucksack is in close contact with your back, you can raise the rucksack to the position of your back, so you can make the backpack with a brilliant impression.

  Further, according to the inventions according to claims 1 to 5, since the length of the strap can be adjusted with one hand while the strap is applied, both hands are not blocked for adjusting the length of the strap.

  First, a basic matter of creation of the present invention will be briefly described. The inventor is mainly engaged in the planning, manufacturing, and sales of fishing bags, and in recent years, outdoor bags and casual bags are also handled. The inventor attaches great importance to practicality as a bag craftsman and has been particular about "easy to store necessary items. Easy to take out and smooth when storing again after that".

  The inventor, when creating the previous invention, paid attention to the fact that many people lowered the shoulder bag to the waist position even if the shoulder bag was closely attached to the back, although the burden on the body was light. . And the shoulder bag is lowered to the waist position, so that the shoulder bag can be turned from the back to the belly so that it can be easily taken out even when the shoulder bag is overlaid. I realized that

  Here, there are some conventional straps whose length can be adjusted, but the conventional straps were intended to adjust the length according to the body shape. Therefore, with conventional straps, once the length is adjusted according to the physique, it is not necessary to change the length frequently, and the length can not be adjusted smoothly with the shoulder bag hanging over.

  Therefore, the inventor can adjust the length of the strap smoothly and quickly even when the shoulder bag is overlaid, so that the shoulder bag can be moved from the back to the stomach only when the contents of the shoulder bag are taken out. It is only necessary to lengthen the strap so that it can be turned, and it has been found that the shoulder bag can be carried close to the back, and the present invention has been created.

  The inventor provided a new function of the strap such as adjusting the length with one hand while keeping the strap hanging on the previous invention, and provided a strap that can respond to a wide range of height and physique differences. I came to hear the desire to want.

  In addition to the shoulder bag, the inventor has heard a request for providing a rucksack.

  Therefore, the inventor can handle a wide range of adult men, adult women, and children with a single strap as long as it has a better length adjustment function than the previous invention, and is shorter than a shoulder bag. It has been found that a strap whose length can be adjusted with one hand can be attached to a rucksack to which the strap is attached, and the present invention has been created.

  Next, embodiments of the present invention will be described in detail with reference to the drawings as appropriate. FIG. 1 is a perspective view of a shoulder bag according to the embodiment. As shown in FIG. 1, the shoulder bag 1 includes a strap 2 and a bag body B.
