Description

  The present invention relates to a shoulder strap, a portable carrying device, and a shoulder pad for a shoulder strap, which can give a particularly suitable form when used or not used.

  2. Description of the Related Art Conventionally, as a device for adjusting the length of a shoulder strap (hereinafter, abbreviated as “strap” as necessary), a length adjusting unit generally called a feed can is known. This adjuster, called a feed can, is provided with a pair of intermediate shafts provided with a central shaft, one end of the belt is attached to the central shaft, the other end is pulled out from the central shaft and wound, and the other end is defined by the central shaft. By inserting into one of the windows from the drawer side and pulling out again from the other window, a doubled part and a single part of the belt are formed. And the effective length of the strap to be used can be adjusted by changing the ratio of the double part and the single part.

  That is, in order to use a strap using such an adjustment part for a shoulder or a hook, depending on the physique and the usage situation, the adjustment part sends out the belt from one side of the flat ring to the other, and the single part of the belt It is widely used to adjust the strap length by changing the ratio of the double part.

  This type of strap has a shoulder pad slidably inserted in the center of the belt or detachably attached with a simple fastener, and the pad inserted through the belt is slid and placed at the shoulder apex position. Usually, the load on the shoulder is distributed by applying a load to the apex of the shoulder.

  Further, there are many rotating shafts provided between the end of the strap and the bag or the like, and the twisting of the entire belt can be prevented or eliminated on this rotating shaft.

  For example, Patent Document 1 can be cited as a related item.

Special table 2009-538678 gazette

  However, the strap provided with the conventional feeding can type adjusting portion is for length adjustment only, and does not fold or store the strap. For this reason, there is a risk that when the portable transporter is placed, the strap may hang down, and a foot may be taken by the strap that forms a large ring. There is also a problem that when the strap is hung, secondary stains occur on clothes and the like through the strap.

  Also, the operation of adjusting the length of the strap requires sending out the belt little by little with respect to the flat ring, and the operability is very poor in order to change the length frequently according to the form of use.

  Furthermore, the length adjustment function enables adjustment between whether the entire area of the belt is single or double, and the adjustment range is limited to almost half of the entire length of the belt. Since 1 corresponds to this, the adjustment margin is narrow, and there are cases where a plurality of straps have to be prepared depending on the type of the portable carrier and the physique of the user.

  In addition, the conventional strap has a rotating part at the connection part of the belt and the portable carrier, and other parts are connected in series. For example, to eliminate the twist of the shoulder pad, the end of the strap It is necessary to rotate the entire strap from the section. Moreover, when the strap is in contact with the shoulder, it is difficult to rotate due to interference with the body, and the rotation shaft also interferes with the portable carrying device, making it difficult to rotate. There was a problem that it was difficult to contribute.

  Furthermore, in the case of a movable type in which the shoulder pad is slidably inserted into the belt or detachable by a simple fastener, the belt is kinked during walking, bending, etc. even if it is positioned at the top of the shoulder. As a result, the kinking of the belt interferes with the pad, so that a problem that the pad supported by the apex of the shoulder is displaced or slipped off easily occurs. Further, using the strap in such a twisted state or a shifted state causes an excessive burden on the shoulder, and there is also a problem of inducing and promoting a stiff shoulder, a headache derived from the stiff shoulder, a back pain, and the like.

  The present invention has been made paying attention to these problems, and can solve the problem of drooping of the strap instantly by a simple operation of pulling the belt, and twisting of the strap can be easily and accurately prevented. It is an object of the present invention to newly provide an innovative strap, a portable transport device, and a shoulder pad for the strap that completely eliminates various problems associated with the strap.

  In order to achieve this object, the present invention takes the following measures.

  That is, the present invention includes a pullout ring in a part, and the belt is divided (separated) into a shoulder region that forms the effective length of the strap and a pullout region that does not form the effective length of the strap through the pullout ring. The end ring member is restrained when a load in a predetermined direction is applied to the shoulder region, and the pull region is pulled when the shoulder region is pulled in a direction different from the predetermined direction. The end belt member can be opened when pulled, and the effective length of the strap can be changed by continuously moving the end belt member from one of the shoulder region or the pull-out region to the other when opening. A shoulder strap is constructed.

  With this configuration, the length can be adjusted instantaneously by simply pulling, compared to the feed ring, and the adjustment can ensure a large adjustment margin using the entire length of the end belt member. The shoulder part can be stored instantly.

  In order to prevent the entire sagging, a detachable part is provided in a part of the drawer region, and the detachable part is detachably connected to the other part of the belt at the withdrawal destination, whereby the belt is integrated. The shoulder strap is effective.

  In order to make the prevention of drooping more reliable, the attachment / detachment part is further provided with a second pull-out ring, and a pull-out area pulled out from the pull-out ring is further removed from the pull-out ring by the second pull-out ring. The second pull-out ring is divided into a folding area up to the second pull-out ring and a surplus length area from the second pull-out ring, and the second pull-out ring is drawn when the folding area is pulled in a predetermined direction. The end belt member can be opened when the folding region is pulled in a direction different from the predetermined direction, and the end belt member is continuously moved from the folding region to the extra length region at the time of opening. Thus, a third shoulder strap that can fold the belt is effective.

  In order to construct the portable carrier by attaching the first shoulder strap to the carrier body, pulling the drawer region when the drawer ring is opened shortens the effective length of the strap so that the shoulder region becomes the carrier body part. It is preferable to construct the strap so that the effective length of the strap can be extended by pulling the shoulder region indirectly through the operation of lifting the drawer ring.

  In order to attach the second shoulder strap to the carrier main body to constitute a portable carrier, the shoulder strap according to claim 2 is attached to the carrier main body, and the drawer region is opened when the drawer ring is opened. By pulling on the strap, the effective length of the strap is shortened, and the detachable part provided in a part of the drawer area is connected to the other part of the belt, so that the drawer area is gathered together with the shoulder area to hang down from the carrier body. On the other hand, it is preferable that the effective length of the strap can be extended by indirectly pulling the shoulder region through the operation of releasing the connection and lifting the pull-out ring.

  In order to construct the portable carrier by attaching the third shoulder strap to the carrier body, the shoulder strap is attached to the carrier body, and the strap is pulled by pulling the drawer region when the drawer ring is opened. By pulling the extra length area by connecting the detachable part provided in a part of the drawer area to the other part of the belt and pulling the extra length area, It is preferable that the effective length of the strap can be extended by indirectly pulling the shoulder region through the operation of releasing the connection ring and lifting the pull-out ring while being folded along.

  In this case, it is more preferable that a binding means for binding the extra length region to the folding region is provided on a part of the belt so as to be movable along the longitudinal direction of the belt.

  On the other hand, as another configuration of the present invention, the belt is divided into at least a central belt member and end belt members on both sides thereof, and the central belt member constitutes a fixed shoulder pad, and the central belt member It is also effective to form a shoulder strap by having a rotating shaft at the divided portion of the belt and the end belt member, and providing a connecting portion for attaching to the portable carrier on a part of the end belt member.

  In this case, since the rotating part blocks the movement of the central belt member and the end belt member, the shoulder pad formed by the central belt member is not easily displaced, and even if the pad is twisted, it is independent about the rotation axis located near the pad. Torsion can be eliminated instantaneously. In addition, since the shoulder pad is a fixed type provided on the central belt member, the shoulder pad is not displaced.

  In this case, in order to increase the degree of freedom in usability, it is preferable that the length adjusting portions are provided on the end belt member side with respect to the rotating shaft.

  In order to further enhance the adjustment function at that time, the length adjusting part is provided with a pull-out ring in part, and the belt is connected to the effective length of the strap and the effective length of the strap through the pull-out ring. A pull-out region that is not configured, and the end ring member is restrained when a load in a predetermined direction is applied to the shoulder region, and the shoulder region is different from the predetermined direction. The end belt member can be opened when it is pulled or when the drawer region is pulled, and the end belt member is continuously moved from one of the shoulder region or the drawer region to the other when the strap is opened. It is extremely effective to be able to change the effective length of.

  In order to appropriately apply such a shoulder strap having a rotating shaft to a portable transporter, both ends of the shoulder strap are detachably attached to a transporter body having at least two support portions, and It is effective to arrange the rotary shaft at a position where it does not interfere with the carrier body.

  Of course, when configuring a shoulder strap having these rotating shafts, an attaching / detaching portion is provided at both ends via the rotating shaft, and the attaching / detaching connecting portion existing in a part of the existing strap is removed from this attaching / detaching portion, and the central belt member. If a shoulder strap shoulder pad is constructed by adopting one that is compatible with the side, the function of the shoulder strap can be remarkably enhanced by simply replacing a part of the existing shoulder strap.

  Since the present invention has the configuration described above, the strap length can be adjusted in an instant with a very simple operation of pulling the end of the belt with both hands, and the strap length can be adjusted to a large extent. As a result, it is possible to easily and appropriately eliminate the inconvenience of taking a foot on the strap ring, and if such a configuration is developed, the drooping of the strap can be effectively prevented and hygiene can be achieved. It is possible to ensure a typical use state.

  In addition, by introducing a fixed shoulder pad and rotating shafts on both sides of the shoulder pad, it is possible to obtain a state where the shoulder pad is always properly applied to the top of the shoulder, and the strap can be twisted with the strap placed on the shoulder. In addition to being able to be suppressed or easily eliminated, if such a configuration is developed, the end belt members on both sides of the shoulder pad can be freely adjusted to accommodate any posture and way of holding. You can get a degree of freedom.

The figure corresponding to FIG. 5 which shows the modifications other than the above of this invention.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  A bag A which is a portable carrier of the present embodiment shown in FIG. 1 has a shoulder strap B on a support portion 11 a provided on at least two left and right sides of the bag body 1, specifically, a side wall 11 constituting the thickness of the bag body 1. Is used by hooking. Although the support part 11a of this embodiment uses what is called a loop-shaped metal fitting, what is called a D ring, the form of the support part 11a is not restricted to this.

  As shown in FIGS. 1 and 2, the strap B is divided into a central belt member 2 and left and right end belt members 3 and 3, and the central belt member 2 itself is constituted by a shoulder pad 20. In addition, the central belt member 2 and the left and right end belt members 3 are connected by a joint member 4 having a rotation shaft 41.

  The joint member 4 has a loop-shaped metal fitting, that is, a so-called D-ring connecting tool 42 attached to the end of the central belt member 2, and a pull-out ring 43 connected to the connecting tool 42 via a rotating shaft 41. is there.

  The pull-out ring 43 is generally also referred to as a “koki type”. As shown in FIG. 3, the drawer ring 43 is provided with a middle shaft 43b in the flat ring 43a, and one of a pair of windows 43c and 43c defined by the middle shaft 43b. The inserted belt C is folded and pulled out from the other side so that the belt C is hooked on the middle shaft 43b. The outer frame 43a1 of the flat ring 43a is displaced in the opening direction of the window 43c with respect to the middle shaft 43b. Yes. Then, as shown in the drawing (b), the double portions c1 and c2 of the belt C are overlapped from the middle shaft 43b toward the outer frame 43a1 of the flat ring 43a and pulled in the direction of pressing. The belt C is restrained (locked) when being pulled, and at least one of the tension states different from the above, for example, the opening direction of the window as shown in FIG. 3 (c in FIG. 3C, both in FIG. 3D) has a function that allows the belt C to be released (released) when pulled without being pressed against the outer frame 43a1 of the flat ring 43a. .

  Then, as shown in FIGS. 1 and 2, the other end 3b of the shoulder pad 20 side of the end belt member 3 is engaged with the pull-out ring 43 provided on the side close to the shoulder pad 20 and folded back. Thus, the end belt member 3 extends from the end portion 3a close to the connection position to the support portion 11a of the bag body 1 to the pull-out ring 43, and forms a loop-shaped shoulder portion together with the central belt member 2, and a pull-out ring 31 It is divided into a pull-out region 32 which is between 43 and the other end 3b and does not constitute a shoulder portion. A connecting member 5 such as a snap hook for detachably attaching the strap B to the support portion 11a of the bag body 1 is provided at the one end portion 3a. The connecting member 5 is compatible with a common connecting member used for an existing strap and shared by the detachable structure.

  Further, as shown in FIG. 2, attachment / detachment portions 61, 61 for connecting or disconnecting the left and right end belt members 3, 3 to a part of each of the pull-out regions 32 of the left and right end belt members 3. Connection members 6, 6 'having' are provided. The attachment / detachment portions 61 and 61 ′ have, for example, a relationship between a male buckle element and a female buckle element, and constitute an attachment / detachment connection portion by engaging with each other. The effective length L of the strap B shown in FIG. The distance from the connecting portion of one connecting member 5 to the connecting portion of the other connecting member 5) is the longest on the shoulder region 31 and the shortest on the drawer region 32, and the detachable portions 61 and 61 'are When it approaches, it becomes the most pulled out state, and the shoulder region 31 is the shortest, the pulling region 32 is the longest, and the shortest when the connecting member 5 is closest to the pulling ring 4.

  Further, as shown in FIG. 2, the connecting member 6 is integrally provided with a second pull-out ring 62 together with the detachable portions 61 and 61 ′. The second pull-out ring 62 further includes a folding region 32 a extending from the pull-out ring 43 to the second pull-out ring 62, and a surplus length beyond the second pull-out ring 62. This area is divided into areas 32b. The second pull-out ring 62 is also of a so-called foot type having the same structure and function as the first pull-out ring 43 described with reference to FIG.

  As shown in FIG. 2 and the like, the surplus length region 32b and the folding region 32a are both inserted through a loop ring 33 which is a binding means, and the loop length 33 binds the surplus length region 32b to the folding region 32a. The belt C does not vary. The loop ring 33 is movable along the longitudinal direction of the belt C constituting the folding region 32a and the extra length region 32b.

  The shoulder pad 20 is made of a material having high cushioning properties, and one surface 20a and the other surface 20b forming the front and back are made of materials having different friction coefficients. In the present embodiment, one surface 20a is slippery and the other surface 20b is not slippery.

  Since the rotating part 41 is provided between both sides of the shoulder pad 20 and the end belt member 3, the rotating part 41 is in a state where the effective length L of the strap B is appropriately extended as shown in FIG. It is arranged at a position where it does not interfere with the bag body 1.

  Next, a method for handling the strap B in this embodiment will be described. When the strap B is hung on the shoulder as shown in FIGS. 7A and 7B with the effective length L extended to some extent as shown by the solid line in FIG. 1, the shoulder belt of the end belt member 3 is loaded by the load of the bag body 1. The region 31 is pulled in the extending direction of the central belt member 2, and at this time, the pull-out ring 43 restrains the end belt member 3 in the state shown in FIG. 3B, so that the length relationship between the shoulder region 31 and the pull-out region 32 is lost. The adjustment position will not shift.

  On the other hand, by pulling down the bag body 1 from the shoulder and pulling the drawer region 32 in a direction different from a predetermined direction, for example, in a direction away from the left and right as shown by arrows in FIG. In order to open the end belt member 3 in the state of FIG. 3D, the belt C continuously moves from the shoulder region 31 toward the pull-out region 32 as shown by the imaginary line in the figure. As shown in FIG. 4, the effective length L of the strap can be shortened, and at least the shoulder pad 20 can be accommodated along the outer periphery of the bag body 1, particularly along the top 12, as shown by the solid line in FIG.

  On the contrary, if the shoulder region 31 is pulled indirectly downward from this state through the operation of lifting the pull-out ring 43 as shown by the imaginary line in the figure, the pull-out ring 43 is in the state shown in FIG. As the member 3 is released, the belt C continuously moves from the pull-out region 32 toward the shoulder region 31, so that the effective length L of the strap can be extended as shown by the solid line in FIG.

  Further, in the present embodiment, the attaching / detaching portions 61 and 61 ′ provided in the pull-out region 32 are picked from the state shown by the solid line in FIG. 4, and the attaching / detaching portions 61 and 61 are mutually attached at the upper part of the bag body 1 as shown by the imaginary line in FIG. By connecting 61 ', the drawer region 32 is brought together to prevent drooping, and as shown by the arrow in the figure, the remainder pulled out from the second drawer ring 62 provided integrally with the attaching / detaching portion 61. By pulling the long region 32b away from each other, the pull-out ring 43 opens the end belt member 3 in the state of FIG. 3C or FIG. 3D, and the folding region 32a is indicated by an arrow in FIG. As a result of the belt C continuously moving toward the surplus length region 32b, the pull-out region 32 can be folded onto the top portion 12 of the bag body 1 in the shortest state. Conversely, from this state, as shown in FIG. 6, if the attachment / detachment portions 61 and 61 'are picked and pulled upward, the folding region 32a is pulled obliquely downward, and the drawer ring 43 is in the state of FIG. 3 (d). In order to open the end belt member 3, the belt C is continuously drawn from the surplus length region 32b toward the folding region 32a. As a result, the end belt member 3 is loosened and the connection state of the attaching / detaching portions 61 and 61 'is released. can do. Of course, if possible, an operation for releasing the attaching / detaching portions 61 and 61 ′ may be performed while being tightened.

  That is, the strap B is pulled on the upper part of the bag A, the belt C is pulled (see FIG. 4), fastened (see the imaginary line in FIG. 5), and pulled (see the solid line in FIG. 5). The belt C can be accommodated, and on the contrary, the attachment / detachment portions 61 and 61 ′ are pulled up (see FIG. 6), disconnected (see the solid line in FIG. 4), and lifted up (see the imaginary line in FIG. 4). The belt C can be pulled out through a series of operations.

  As described above, the shoulder strap of the present embodiment includes a pull-out ring 43 in part, and the belt C is passed through the pull-out ring 43 so that the shoulder strap 31 and the effective length of the strap B constituting the effective length L of the strap B can be obtained. When a load in a predetermined direction is applied to the shoulder region 31 in the usage state shown in FIGS. 7A, 7B, etc. The end belt member 3 is restrained and the end belt member 3 is released when the shoulder region 31 is pulled in the direction of FIG. 4 different from the predetermined direction or when the pull-out region 32 is pulled as shown in FIG. It is configured so that the effective length L of the strap can be changed by continuously moving the end belt member 3 from one of the shoulder region 31 or the drawer region 32 to the other when opened. Than is.

  For this reason, compared to the case of the feed ring, the length can be adjusted instantaneously by simply pulling, and the adjustment can ensure a large adjustment margin using almost the entire length from end to end of the end belt member 3. The shoulder portion that forms the loop can be stored instantly, and inconveniences such as being able to take a foot can be effectively eliminated. Since at least the shoulder pad 20 fits at least along the top 12 that is the outer periphery of the bag body 1 and does not hang down on the floor, the most contacting part of the body can be effectively prevented from being damaged. Even if it remains in FIG. 4, the amount by which the end belt member 3 hangs can also be suppressed.

  As long as such an effect is obtained, the detachable portions 61 and 61 ′ are not indispensable requirements in a part of the drawer region 32, but in the present embodiment, the detachable portions 61 and 61 ′ are provided at the drawer destination. As shown by an imaginary line in FIG. 5, detachable connections are made together to prevent drooping, so that not only the shoulder pad 20 but also the drawer region 32 is hung from the bag body 1 to the floor. Thus, it is possible to more effectively prevent pollution. Moreover, since the strap B itself has such a sag prevention function, it is not necessary to provide the bag body 1 with a detachable part such as a pocket or a take-up reel, and it does not depend on the structure or function of the bag body 1. The function can be completed with only the strap B.

  Furthermore, as long as these effects are obtained, the second pull-out ring 62 is not an essential requirement, but in the present embodiment, the second pull-out ring 62 is further provided integrally with the detachable portions 61 and 61 ′. The pull-out region 32 pulled out from the pull-out ring 43 is further folded by the second pull-out ring 62 into a folding region 32a from the pull-out ring 43 to the second pull-out ring 62, and the remaining length beyond the second pull-out ring 62. This area is divided into areas 32b. When the left and right folding regions 32a and 32a are tightened as shown in FIG. 5 and pulled in a predetermined direction, the drawer region 32 is restrained, and the folding regions 32a and 32a are shown in FIG. The end belt member 3 can be opened when it is pulled in a direction different from the predetermined direction by the lifting operation as in FIG. 6, and the belt C is continuously moved from the folding region 32a to the extra length region 32b when opened. In addition, since the entire strap is converged on the outer periphery (particularly the top portion 12) of the bag body 1 so that it can be folded, a state without drooping can be created.

  Furthermore, since the surplus length region 32b is bundled in the folding region 32a by the loop ring 33, even if this bag is placed on a net shelf of a train, for example, the drooping of the strap B can be completely eliminated.

  Even if the shoulder pad 20 may slip off from the top 12 of the bag body because the folding force is halfway, the shoulder pad 20 on the front or back of the bag body 1 as shown by the imaginary line in FIG. In this case, the sag prevention function is surely ensured.

  On the other hand, in this embodiment, an advantage in handling due to the introduction of the rotating part 41 into a part of the strap B will be described.

  This type of strap is used in the state of a shoulder (see (a) in the figure) or a hook (see (b) in the same figure) as shown in FIG. Twist such as when B is twisted or when strap B is twisted by moving bag A to the front of the body as shown in FIG. There are many reasons for this.

  On the other hand, in the present embodiment, since the rotation shaft 41 is provided between the shoulder pad 20 and the end belt member 3 constituting the central belt member 2, the movement between the shoulder pad 20 and the end belt member 3 is caused by the rotation shaft 41. Are cut off, and each can independently rotate around the axis of the rotation shaft 41. Further, the shoulder pad 20 and the end belt member 3 are located at both ends of the shoulder pad 20 and are not easily pressed against the body and are not easily interfered with the bag body 1. It can be easily rotated without interfering with. For this reason, it is easy to suppress the twist even if the strap B is shouldered and hooked from any posture, and the twist is eliminated by simply inverting the shoulder pad 20 of the strap B or the end belt member 3 with one hand. Moreover, since the direction of the surface of the belt follows the body, the state where the strap B is always in close contact with the body can be maintained. Further, by completely suppressing the twist of the strap B, the bag A can be supported stress-free without worrying about the twist. Furthermore, when the position of the shoulder pad 20 is always at the top of the shoulder and can be kept in close contact with the body as described above, the load of the bag body 1 is dispersed and the strap B is always imitated to the body. It is easy to move and eliminates the need to hold the strap frequently, reducing the burden on the body, so it is possible to obtain a comfortable feeling that can be expected to prevent stiff shoulders, back pain and headache. .

  In addition, since the central belt member 2 itself is a fixed shoulder pad 20, the strap B does not have a problem that only the shoulder pad part slides and slips, and the shoulder pad 20 is always maintained at the adjusted position. It can be used stably.

  Furthermore, since the rotating shaft 41 is provided on both sides of the shoulder pad 20, only the shoulder pad 20 can be simply rotated while the strap B is used, and the front and back surfaces can be instantaneously reversed. And since the material from which a friction coefficient differs is used for the front and back of a shoulder pad, according to the use condition of the bag 1, the front and back can be used properly. For example, as shown in FIG. 7 (a), when the bag A is used on one shoulder, the strap B is prevented from slipping off or sliding off from the shoulder by using the surface of the material with a high friction coefficient on the body side. When changing the bag A from the one-shoulder-hanging state as shown in FIG. 2 (a) → (b), the shoulder pad 20 is rotated while the strap B is used, and the friction coefficient is changed. The material of the shoulder pad 20 can be properly used depending on how the bag 1 is held.

  Further, as shown in FIG. 1 and the like, a pull-out ring 43 that can be used as a length adjusting unit is provided on the end side of the rotating shaft 41, and the lengths of the left and right end belt members 3 can be adjusted independently. For example, when the bag A is supported by the back like a messenger bag as shown in FIG. 8A, or when the bag A is positioned in front of the body as shown in FIG. In this case, the shoulder pad 20 of the strap B can always be adjusted to be positioned at the apex of the shoulder, and the shoulder pad 20 will not slide even after the adjustment, so that the adjusted state can be reliably maintained. The mode of free use according to how to hold becomes possible.

  In addition, since the pull-out ring 43 serving as the adjusting portion is a so-called koki type, it is possible to increase the length of the strap C and to adjust the length as in the conventional strap. A complicated operation such as feeding out the belt little by little with the adjustment operation is unnecessary, and a very simple operation such as pulling the drawer region 32 as shown in FIG. 1 or lifting the drawer ring 43 as shown in FIG. If it carries out individually or simultaneously with respect to the pull-out rings 43, 43, the length of the end belt members 3, 3 can be adjusted individually or in conjunction with each other, thereby obtaining a new function that has not been achieved in the past. be able to.

  Furthermore, the present embodiment is compatible with the existing strap through the connection portion 5, so that one strap B can be used for general purposes, and repair and replacement can be partially facilitated even if it is damaged. In addition to being economical and easy to store, it can be applied to portable transporters of all sizes and shapes, including not only bags but also equipment cases, cases without casters, golf bags and instrument cases. Become.

  The specific configuration of each unit is not limited to the above-described embodiment.

  For example, as long as the strap C is pulled so that it does not hang down on the floor using the pull-out type pull-out ring 43, and is connected and folded so as to fit along the bag body 1, the central belt member 2 does not necessarily need to be provided between the shoulder pad 20 and the end belt member 3, and the shoulder pad 20 may be slidable.

  On the other hand, the strap C is divided into three parts, the central belt member 2 is used as a fixed shoulder pad 20, and the rotating shaft 41 is used at the divided part of the central belt member 2 and the end belt member 3, thereby eliminating twisting and each end belt. Insofar as the effect obtained by providing the adjusting portion on the member 3 and performing individual adjustment is obtained, it is not an essential requirement to use a koki-type drawer ring for the length adjusting portion.

  In this case, as shown in FIG. 9, it is also effective to provide a detachable connection portion 100 between the central belt member 2 and the end belt member 4. In the illustrated example, the central belt member 2 is constituted by a shoulder pad 20, and a connecting tool 42 such as a D-ring is attached to the end of the central belt member 2, and a female constituting the attaching / detaching part 100 via the rotating shaft 41. A mold buckle element 100a is provided, and the end belt member 3 is provided with a male buckle element 100b and a pull-out ring 43 that is integrated with the male buckle element 100b. The attachment / detachment part 100 found in this type of buckle element has a standard, and if the same standard is used, the attachment / detachment connection part existing in a part of the existing strap is removed to make it compatible with the central belt member side. Therefore, it is possible to easily adopt a configuration in which the rotating shaft 41 is provided at both ends of the fixed shoulder pad 20 by simply replacing the strap of the bag already possessed.

  Moreover, as shown in FIG. 10, the bag main body 1 which is the portable carrier main body to which the strap is applied is provided with a support portion 12a for attaching the strap connection portion to the top portion 12 constituting the thickness. May be. In this case, the distance between the support portions 12a and 12a is shorter than the distance between the support portions 11a and 11a of the above embodiment. However, if the strap B similar to the above is used, the drawer is pulled out as shown in FIGS. By pulling the region, connecting the connecting portions 61 and 61 'as shown in FIG. 1 to FIG. 12, and pulling the extra length region 32b, it is folded very compactly and stored in the top of the bag body. Therefore, even in this type of bag, it is possible to completely eliminate the inconvenience of the strap hanging.

  Further, even if the connecting portion 105 of the strap B to the bag body 1 is integrated by sewing with a presser cloth 111a as a supporting portion provided in the bag body 1 as shown in FIG. The effect of using the strap to prevent dripping and the effect of providing the rotating shaft 41 between the shoulder pad 20 and the end belt member 3 constituting the central belt member 2 by dividing the strap into three are completely the same as in the above embodiment. It can be obtained similarly.

  Furthermore, the aspect which accommodates the strap B along the outer periphery of the bag main body 1 which is a carrier main body may be wound around the bottom 13 side of the bag main body 1 as shown in FIGS. . In this case as well, the other configurations are the same as described above.

  By the way, in any of the above-described embodiments and modifications, the drawer ring 43 is provided on the side close to the shoulder pad 20, and the one end 3 a close to the connection position with respect to the support portion 11 a of the bag body 1 is connected to the bag body 1 via the connection member 5. The effective length L of the strap B is adjusted on the side of the pull-out ring 43 close to the shoulder pad 20 as shown in FIGS. 15, 16 and 17 corresponding to FIGS. 1, 4 and 5, respectively. As described above, a pull-out ring 143 is provided on one end side 3a on the side close to the connection position with respect to the support portion 11a of the bag body 1 in use, for example, by being integrated with a connection member 5 such as a snap hook. The effective length L of the strap B can be adjusted on the 143 side.

  That is, the end belt member 3 is pulled out from the other end portion 3b close to the central belt member 2 by engaging the pull-out ring 143 with the end belt member 3 on the end portion 3a side close to the bag body 1 and turning it back. It can be divided into a shoulder region 131 that extends to 143 and constitutes a loop-shaped shoulder portion together with the central belt member 2 and a drawer region 132 that does not constitute a shoulder portion between the drawer ring 143 and the one end portion 3a.

  Also in this case, a connecting member having attachment / detachment portions 61 and 61 ′ for connecting or disconnecting the left and right end belt members 3, 3 to a part of each of the drawing regions 132 of the left and right end belt members 3. 6 and 6 ′ are provided, and the connection members 6 and 6 ′ are integrally provided with a squeezed second drawer ring 162 together with the detachable portions 61 and 61 ′. The second pull-out ring 162 also includes a pull-out region 132 drawn out from the pull-out ring 143, a folding region 132a from the pull-out ring 143 to the second pull-out ring 162, and an extra length beyond the second lead-out ring 162. This area is divided into areas 132b.

  Even in this configuration, when the strap B is hung on the shoulder in the state of FIG. 15, the pull-out ring 143 restrains the end belt member 3, while the pull-out region 132 located on the side of the bag body 1 is positioned upward. As the belt C continuously moves from the shoulder region 131 toward the pull-out region 132 when pulled toward the rear, the effective length L of the strap is shortened as shown in FIGS. It can be accommodated along the outer periphery, particularly the top portion 12, and the detachable portions 61, 61 ′ provided in the drawer region 32 are connected to each other at the upper portion of the bag body 1, and the extra length region 32 b is pulled away from each other. As shown in FIG. 17, as a result of the belt C being pulled out from the folding region 132a toward the extra length region 132b in the second pull-out ring 162, the pull-out region 13 It can be folded on top 12 of the bag body 1 in the shortest state. When pulling out the strap B, if the detachable portions 61 and 61 'are released and the second pullout ring 162 and the pullout ring 143 are operated so that the belt C moves in the direction opposite to the above, FIG. 16 → The strap B can be pulled out and used in the procedure of FIG.

  Further, the advantage that the lengths of the end belt members 3 and 3 can be adjusted independently in each of the pull-out rings 143 and 143 is the same as in the above embodiment.

  In the case of FIG. 15 to FIG. 16, the Koki-type drawer ring 43 used in the above embodiment is also provided on the other end 3 b side of the belt C, and the strap B is also effective in this Koki-type drawer ring 43. Since the length L is adjustable, this strap B constitutes a double adjuster mechanism that adjusts the effective length L of the strap B in cooperation with the foot-shaped pull-out rings 43, 143 located on both sides of the shoulder region 131. In addition, it can be used as a more convenient one that can adjust the length of each end belt member 3 in the vicinity of the shoulder pad 20 and the bag body 1.

  In this sense, it is also effective to provide a foot-type drawer ring on the one end 11a side of the belt C shown in FIG.
