  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.

As shown in FIG. 3, the drawer ring 43 is generally referred to as “Koki type”, and includes a middle shaft 43b fixed in the flat ring 43a, and a pair of windows 43c and 43c defined by the middle shaft 43b. The belt C inserted into one of the belts is folded back and pulled out from the other, so that the belt C is hooked on the center shaft 43b. The outer frame 43a1 of the flat ring 43a is in the opening direction of the window 43c with respect to the center shaft 43b. It is displaced. 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. Accordingly, 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 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. The other end portion (drawing end) 3b side is a free end, and both the shoulder region 31 and the drawing region 32 are inserted through the loop ring 30 as a binding means. 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 attached to one end portion 3a which is the end portion of the end belt member 3 opposite to the central belt member 2. Is provided. 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 on the drawer ring 43 . When it approaches, it becomes the most drawn out state, and the shoulder region 31 becomes the shortest and the pulling region 32 becomes the longest and becomes the shortest when the connecting member 5 comes closest to the pulling ring 43 .

  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 rotary shaft 41 is provided between both sides of the shoulder pad 20 and the end belt member 3, the rotary shaft 41 is as shown in FIG. 1 in a state where the effective length L of the strap B is appropriately extended. 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 pulled in a predetermined direction with respect to the pull-out ring 43 in the state of FIG. The length relationship between the shoulder region 31 and the drawer region 32 is not broken, and the effective length L of the strap B is fixed, so that the adjustment position is not shifted.

On the other hand, when the bag body 1 is lowered from the shoulder and the pulling region 32 is pulled in a direction different from a predetermined direction with respect to the pulling ring 43 , for example, in a direction away from the left and right as shown by arrows in FIG. As a result of opening the end belt member 3 in the state of FIG. 3C or FIG. 3D, the belt C continuously moves from the shoulder region 31 toward the pull-out region 32 as indicated by an imaginary line in the drawing. The effective length L of the strap can be shortened as shown by an imaginary line in the figure, and at least the shoulder pad 20 can be accommodated along the outer periphery of the bag body 1, particularly the top part 12 as shown by a solid line in FIG. 4.

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. That is, the pull-out ring 43 can fix the effective length L of the strap B on the left and right sides of the central belt member 2 when restrained, and can change the effective length L of the strap B on the left and right sides of the central belt member 2 simultaneously or individually when opened. It is what.

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. By connecting 61 ', the pull-out region 32 is brought together to prevent drooping, and as shown by the arrow in the figure, it is pulled out from the second pull-out ring 62 provided integrally with the detachable parts 61 , 61'. By pulling the surplus length regions 32b away from each other, the second pull-out ring 62 opens the end belt member 3 in the state of FIG. 3 (c) or FIG. 3 (d). As shown in the drawing, the belt C continuously moves from the folding region 32a toward the extra length region 32b. As a result, the drawer region 32 can be folded to the top portion 12 of the bag body 1 in the shortest state. Conversely, from this state, as shown in FIG. 6, if the detachable portions 61 and 61 'are picked and pulled upward, the folding region 32a is pulled obliquely downward, and the second pull-out ring 62 is moved to FIG. 3 (d). In order to open the end belt member 3 in this state, the belt C is continuously drawn out from the surplus length region 32b toward the folding region 32a. As a result, the end belt member 3 is relaxed and the connecting portions 61 and 61 'are connected. The state can be released. 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.

On the other hand, in this embodiment, the advantage in handling by introducing the rotating shaft 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.

As described above, in the shoulder strap of the present embodiment, the belt C is divided into at least the central belt member 2 and the end belt members 3 on both sides thereof, and the central belt member 2 and the end belt member 3 are divided. A rotating shaft 41 is provided in the portion, and the rotating shaft 41 is configured such that each of the central belt member 2 and the left and right end belt members 3 can independently rotate in a direction in which the front and back are reversed around the axis of the rotating shaft 41. It is.

For this reason, the movement of the central belt member 2 (shoulder pad 20) and the end belt member 3 is blocked by the rotation shaft 41, and each can rotate around the axis of the rotation shaft 41 independently. Further, the central belt member 2 (shoulder pad 20) is located at both ends of the central belt member 2 (shoulder pad 20) and is not easily pressed against the body, and at the position where it does not easily interfere with the bag body 1, the central belt member 2 (shoulder pad 20). ) And the end belt member 3 can be easily rotated without interfering with the body or the bag body 1. For this reason, it is easy to suppress the twist even if the strap B is shouldered and hooked from any situation and posture, and the central belt member 2 (shoulder pad 20) and the end belt member 3 of the strap B can be easily reversed with one hand. Thus, the twist can be eliminated, and the orientation of the belt surface follows the body, so that the strap B can always be kept in close contact with the body. Further, by completely suppressing the twist of the strap B, the bag A can be supported stress-free without worrying about the twist. Further, when the position of the central belt member 2 (shoulder pad 20) is always at the top of the shoulder and can be kept in close contact with the body in this way, the load of the bag body 1 is dispersed and the strap B is always applied. Since it can be used in a state that mimics the body, it is easy to move and there is no need to re-hold the strap frequently, reducing the burden on the body, so it can be used to prevent stiff shoulders, low back pain, and headaches. Can be obtained.

The present strap B, since the central belt member 2 itself a shoulder pad 20 stationary, maintaining the shoulder pads 20 to no inconvenience only shoulder pad part is displaced by sliding, always adjusted position And can be used stably.

In addition, since materials having different friction coefficients are used for the front and back surfaces of the shoulder pad 20, the shoulder straps B can be appropriately used according to the use state of the bag A using the shoulder straps B of the present invention. .

Further, 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.

Furthermore, the joint member 4 has an attachment / detachment connecting portion 100 by a buckle element 100a for attaching / detaching between the central belt member 2 and the left and right end belt members 3.

On the other hand, the central belt member 2 of the present invention constitutes the shoulder strap B, and a rotation shaft 41 is attached to the end portion via a connection tool 42, and the buckle constituting the detachable connection portion 100 is attached to the rotation shaft 41. The element 100a is provided so that it can be reversed.

Further, since the central belt member 2 itself is a fixed shoulder pad 20, there is no problem that only the shoulder pad portion slides and slips, and the shoulder pad 20 is always kept in an adjusted position and is stable. Can be used for

In addition, since materials having different friction coefficients are used for the front and back surfaces of the shoulder pad 20, the shoulder straps B are appropriately used according to the use state of the bag A using the shoulder strap B including the central belt member 2. be able to.

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. That is, the rotation shaft 41 allows the central belt member 2 and the left and right end belt members 3 and 3 to rotate independently in a direction in which the front and back are reversed around the axis of the rotation shaft 41. 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 A , 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 A 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.

  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.

On the other hand, the central belt member 2 and fixed shoulder pad 20 divided into three parts of the strap C, and with a rotary shaft 41 to the divided portion of the central belt member 2 and the end belt member 3, eliminating or each end of the torsion As long as an effect is obtained by providing an adjustment portion on the belt member 3 and making individual adjustments, it is not an essential requirement to use a foot-type drawer ring for the length adjustment 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 3 . 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. has therefore already easily replaced strap of the bag to be held, it is possible to easily adopt the configuration in which the rotating shaft 41 to both ends of the stationary shoulder pad 20.

  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 of the bag body 1 with respect to the support portion 11 a 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. Thus, in the state of use, the drawer ring 143 is provided on the one end side 3a on the side close to the connection position with respect to the support portion 11a of the bag body 1 by being integrated with the 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 and pulling back the end belt member 3 near the bag body 1 to the end ring member 143. 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 shown in 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 moves 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.

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.

In addition, portable transport devices to which the present invention is applied include various shoulder bags / business bags, various briefcases, notebook cases, document cases, sports bags, camera equipment bags, various equipment bags (broadcasting / business videos). Special cases for equipment and audio equipment), attache cases, Boston bags, messenger bags, musical instrument cases such as strings and wind instruments, various hard cases, garment bags / suitcases, shoulder carry bags, three-way bags, pochettes, weapon cases, surfboard cases scan, etc. including, can be widely deployed on a container or box-like object or bag-like things, such as to support over the shoulder attach the shoulder strap.
