[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-81864 [Patent Document 2] Japanese Patent Application Publication No. 10-46409 [Patent Document 3] Patent No. 6796152 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the pants with lumbar support belts of Patent Documents 1 and 2, the relative positions of the lumbar support belt and the pants body are fixed, making it difficult to adjust the force tightening the waist of the wearer, and therefore the effectiveness of the lumbar support belt cannot be fully achieved.

[0006] Furthermore, in the pants with a lumbar protection belt described in Patent Document 3, the lumbar protection belt is removable, which makes it difficult to put on the lumbar protection belt and also makes it difficult to widen the range of adjustment for tightness.

[0007] The object of the present invention is to provide trousers with a lumbar protection belt, and a method for wearing the same, which make it easy to adjust the tightening force and tightness of the lumbar protection belt while the lumbar protection belt is fixed to the trouser body. [Means for solving the problem]

[0008] Below, the means for solving the problems will be explained using the reference numerals attached to the embodiments in the drawings, but the present invention is not limited to the embodiments attached with these reference numerals.

[0009] The present invention relates to pants with a waist protection belt, which include a pants main body 1a having a front body 2, a back body 3, and a waist area 4 to which the upper ends of the front and back bodies are sewn, and a waist protection belt structure attached to the waist area 4. The pants with a waist protection belt of the present invention have a circumferentially stretchable structure, and first and second side area regions 4c, 4d located between a rear central area 4a and a front central area 4b of the waist area 4 also have a circumferentially stretchable structure. The waist protection belt structure further includes a first belt structure unit 8, a second belt structure unit 9, a first additional belt structure unit 10, a second additional belt structure unit 11, a group of connected members 30, and a third additional connected member 17.

[0010] The first belt structure unit 8 has a first connecting belt portion 80, a first operating belt portion 84, and a first length change mechanism 100 located between the first connecting belt portion 80 and the first operating belt portion 84 to change the overall length. One end of the first connecting belt portion 80 is connected to one end of the rear central region 4a, and when the first operating belt portion 84, which has a first connecting member 85 on its tip side, is pulled, the first length change mechanism 100 deforms so as to move one end of the rear central region 4a closer to the other end of the rear central region 4a.

[0011] The second belt structure unit 9 includes a second connecting belt portion 90, a second operating belt portion 94, and a second length adjustment mechanism 101 positioned between the second connecting belt portion 90 and the second operating belt portion 94 to adjust the overall length. One end of the second connecting belt portion 90 is connected to the other end of the rear central region 4a. Pulling the second operating belt portion 94, which has a second connecting member 95 at its tip, deforms the second length adjustment mechanism 101 to move the other end of the rear central region 4a closer to one end of the rear central region 4a. A group of connected members 30 is provided between the first and second side regions. The first operating belt portion 84 and the second operating belt portion 94 are long enough to allow the first connecting member 85 and the second connecting member 95 to be connected in front of the group of connected members 30. The trousers with a waist support belt according to the present invention can securely fasten the waist support belt structure by utilizing the group of connected members 30 located on the front side of the user.

[0012] The first additional belt structure unit 10 that can be further provided is composed of a first additional operating belt portion 10A whose other end extends circumferentially away from the first side region portion 4c, a first additional connecting member 10B provided at the other end of the first additional operating belt portion 10A, a first additional connected member 10C provided between the first side region portion 4c and the front central region portion 4b of the waist portion 4 and to which the first additional connecting member 10B can be detached and connected, and a first additional connected member 86a provided on the surface of the first additional operating belt portion 10A and to which the first connecting member 85 provided on the first operating belt portion 84 can be detached and connected.

[0013] The second additional belt structure unit 11 is also composed of a second additional operating belt portion 11A whose other end extends circumferentially away from the second side region portion 4d, a second additional connecting member 11B provided at the other end of the second additional operating belt portion 11A, a second additional connected member 11C provided between the second side region portion 4d and the front central region portion 4b of the waist portion 4 and to which the second additional connecting member 11B can be removed and connected, and a second additional connected member 96a provided on the surface of the second additional operating belt portion 11A and to which the second connecting member 95 provided on the second operating belt portion 94 can be removed and connected.

[0014] The group of connectable members 30 can be configured to include at least a first additional connectable member 10C and a second additional connectable member 11C, as well as a first additional connectable member 86a and a second additional connectable member 96a, in a front region located between the first side region portion 4c and the second side region portion 4d. A third additional connectable member 17, to which the first connecting member 85 of the first operating belt portion 84 can be connected, can also be provided on a surface of the second operating belt portion 94 located opposite to the second connecting member 95.

[0015] In one example of wearing the pants with waist protection belt of the present invention, the other end of the first additional operating belt portion 10A and the other end of the second additional operating belt portion 11A are pulled in a direction that stretches the first and second side region portions 4c, 4d circumferentially, respectively, and the first additional connecting member 10B at the other end of the first additional operating belt portion 10A and the second additional connecting member 11B at the other end of the second additional operating belt portion 11A are connected to the first additional connected member 10C and the second additional connected member 11C (first stage adjustment). Then, the wearer grasps the other end 84B of the first operating belt portion 84 of the first belt structure unit 8 and the other end 94B of the second operating belt portion 94 of the second belt structure unit 9 with each hand, and then pulls the other end 84B of the first operating belt portion 84 and the other end 94B of the second operating belt portion 94 in opposite circumferential directions so as to contract the rear central region portion 4a of the waist portion 4 circumferentially and stretch the first and second side region portions 4c and 4d circumferentially.In this state, the second connecting member 95 provided on the other end 94B of the second operating belt portion 94 is connected to at least one connected member included in the group of connected members 30 so as to prevent the second operating belt portion 94 from slackening, and the first connecting member 85 provided on the other end 84B of the first operating belt portion 84 is connected to the third additional connected member 17 of the second operating belt portion 94. In this way, while the second operating belt portion 94 is fixed, the first connecting member 85 of the first operating belt portion 84 can be connected to the third additional connected member 17 of the second operating belt portion 94, so that the first operating belt portion 84 and the second operating belt portion 94 can be tightened and fixed in an appropriate position in front of the operator with no obstructions around them (second stage adjustment).

[0016] In another method of the second stage adjustment, while the other end 84B of the first operation belt portion 84 and the other end 94B of the second operation belt portion 94 are pulled in opposite circumferential directions, the second connecting member 95 provided on the other end 94B of the second operation belt portion 94 is connected to at least one connected member included in the group of connected members 30 so as to prevent the second operation belt portion 94 from slackening, and the first connecting member 85 provided on the other end 84B of the first operation belt portion 84 is connected to at least one connected member included in the group of connected members 30 so as to prevent the first operation belt portion 84 from slackening. In this case, although it is necessary to connect the first operation belt portion 84 to a connected member in the group of connected members 30 while avoiding the second operation belt portion 94, the second connecting member 95 of the second operation belt portion 94 can be connected to the connected member on the front side of the user, so the connecting operation is not particularly inconvenient.

[0017] For example, one example of the first belt structure unit 8 includes a first connecting belt portion 80, a first D-ring 81 fixed to one end of the rear center region portion 4a via the first connecting belt portion 80, a first base belt portion 82 having one end fixed to the other end of the rear center region portion 4a and inserted into the first D-ring 81, and a pair of fixing bars 83a, 83b having a moving bar 83c between them, and the first base belt portion 82 being fixed to one fixing bar 83a. a first operating belt portion 84 having one end 84A fixed to the outer end of the first side region portion 4c and the other end 84B extending toward the outer end of the first side region portion 4c, the first operating belt portion 84 being engaged with a moving bar 83c of the first movable can 83 and bent to pass under the other fixed bar 83b of the first movable can 83;

[0018] An example of the second belt structure unit 9 includes a second connecting belt portion 90, a second D-ring 91 fixed to the other end of the rear center region portion 4a via the second connecting belt portion 90, a second base belt portion 92 having one end fixed to one end of the rear center region portion 4a and inserted into the second D-ring 91, and a pair of fixed bars 93a, 93b having a moving bar 93c between them, and the second base belt portion 92 being fixed to one fixed bar 93a. 2 is connected to a second movable can 93, one end 94A of which is fixed to the outer end of the second side region 4d, a second operating belt 94 which is engaged with a moving bar 93c of the second movable can 93 and bent to pass under the other fixed bar 93b of the second movable can 93 and extend to the outer end of the second side region 4d, and the other end 94B of the second operating belt 94 has a second connecting member 95. In this case, the second length change mechanism 101 is configured to include the second D-ring 91, the second base belt 92, and the second movable can 93. The configurations of the first length change mechanism 100 and the second length change mechanism 101 are arbitrary.

[0019] The first operating belt portion 84 may further include a fourth additional connected member 16 that is provided on the surface thereof opposite to the first connecting member 85 and to which the second connecting member 95 of the second operating belt portion 94 can be connected. By adopting such a configuration, the number of connection variations increases, thereby improving usability for the user.

[0020] Furthermore, a first cover portion 14 can be provided to cover the abutting portion between one end 84A of the first operation belt portion 84 and one end of the first additional operation belt portion 10A, and a second cover portion 15 can be provided to cover the abutting portion between one end 94A of the second operation belt portion 94 and one end of the second additional operation belt portion 11A. In this case, a fifth additional connected member 86b included in the connected member group 30 can be provided on the surface of the first cover portion 14, and a sixth additional connected member 96b included in the connected member group 30 can be provided on the surface of the second cover portion 15. Even when such a configuration is adopted, the number of connection variations increases, thereby improving usability for the user.

[0021] The waist portion 4 may be in a normally closed loop state, but if the front body is configured to be openable and closable laterally by a fastener 5 when worn, the waist portion 4 may have a structure in which both end portions 4A, 4B are joined by a metal hook 6 above the fastener 5 when worn. In this case, it is preferable that one end portion 4A of the waist portion 4 is provided with a connecting belt portion 12 and a connecting member 12A fixed to the connecting belt portion 12, and the other end portion 4B of the waist portion 4 is provided with a connecting member 13 to which the connecting member 12A fixed to the connecting belt portion 12 can be detachably connected. By further adopting such a configuration, the tightening force of the lumbar support belt can be further increased by pulling the connecting belt portion 12 to change the fixed position of the connecting member 12A relative to the connecting member 13 (third stage adjustment). Furthermore, if sufficient adjustment can be achieved through the two-stage adjustment described above, it is possible to connect the connecting member 12A to the connecting member 13 without pulling the connecting operation belt portion 12, thereby making it unnecessary to perform the third stage of adjustment.

[0022] A seventh additional connected member 12B may be provided on the surface opposite to the connecting connecting member 12A fixed to the connecting operation belt portion 12, to which the first connecting member 85 or the second connecting member 95 is detachably and positionally adjustable. By adopting such a configuration, the number of connection variations increases, thereby improving usability for the user.

[0023] It is preferable that the first base belt portion 82 and the second base belt portion 92 are arranged in parallel without overlapping each other, which makes adjustment easier.

[0024] The waist portion 4 may be provided with a plurality of belt loops 20 at predetermined intervals in the circumferential direction for passing movable members of the lumbar protection belt structure. Preferably, one end of the plurality of belt loops 20 is attached to the waist portion 4 by sewing, and the other end is attached to the waist portion 4 with snap buttons 21 so that they can be connected and disconnected. If the belt loops 20 are left open when fastening the lumbar protection belt 7, the fastening operation and the operation of fastening each connecting member and each fixed member can be performed smoothly.

As shown in Fig. 9, from this state, the second connecting member 95 provided on the other end 94B of the second operating belt portion 94 is connected to at least one connected member (e.g., the first connected member 86) included in the connected member group 30 so as to prevent the second operating belt portion 94 from slackening, and the first connecting member 85 provided on the other end 84B of the first operating belt portion 84 is connected to the third additional connected member 17 of the second operating belt portion 94. In this way, with the second operation belt portion 94 fixed, the first connecting member 85 of the first operation belt portion 84 can be connected to the third additional connected member 17 of the second operation belt portion 94. As a result, the first operation belt portion 84 and the second operation belt portion 94 can be fastened and fixed in an appropriate position in front of the operator with no obstructions around.

[0045] It is also possible to connect the first connecting member 85 of the first operating belt portion 84 to at least one connected member (for example, the second connected member 96) included in the connected member group 30 without connecting the first connecting member 85 of the first operating belt portion 84 to the third additional connected member 17 of the second operating belt portion 94.

[0046] In this embodiment, first, the fastening force of the lumbar protection belt 7 can be further increased by pulling the connecting belt portion 12 to change the fixed position of the connecting member 12A relative to the connecting member 13. If sufficient adjustment can be achieved by the above-mentioned two-stage fastening operation, the connecting member 12A can be connected to the connecting member 13 without pulling the connecting belt portion 12.
