Therefore, regarding the belt adjusting device, the belt body is inserted into the belt adjusting device. The direction is the front-rear direction, and the strip width direction orthogonal to the insertion direction of the strip is the left-right direction (width direction), and the direction orthogonal to the front-back direction and the left-right direction is the up-down direction (thickness direction). Further, F, B, L, R, U, and D in the figure are the front, the rear, the left, the right, the upper, and the lower, respectively, based on the direction of the belt adjuster.

As shown in FIGS. 1 and 2, the belt adjusting device 10 is attached to, for example, a shoulder strap of one of the backpacks (not shown), and the other shoulder strap 1 is inserted, and the shoulder strap 1 is adjusted relative to the belt body. The relative position of 10 is used to adjust the length of the strip. The shoulder belt 1 is formed into a thin and thin plate shape using leather, synthetic rubber or the like, and on the surface 2 side of the shoulder belt 1, along the shoulder belt 1 between the locking projections 3c formed by the inclined surface 3a and the vertical surface 3b. A plurality of locking grooves 3 are formed in the width direction, and the racks 4 are formed by the locking grooves 3.

The belt body adjustment tool 10 is assembled by the adjuster main body 11, the locking member 12, and the lid body 13, and the shoulder belt 1 is inserted into the belt insertion hole 18 of the adjuster main body 11.

3 to 6, the adjuster main body 11 includes a substantially rectangular plate-shaped base portion 14 provided on the front surface side of the shoulder belt 1, and a pair of left and right side walls 15R which are respectively erected from the left and right end portions of the base portion 14. 15L and the connecting portions 16F and 16B that connect the pair of side walls 15R and 15L to the front end portions and the rear end portions, respectively, on the side opposite to the base portion 14 (back side). The adjuster main body 11 is formed of a synthetic resin to reduce the weight.

The pair of side walls 15R and 15L and the pair of connecting portions 16F are provided on the back side of the main body 11 facing the base portion 14 16B, a substantially rectangular opening 17 for mounting the cover 13 is partitioned. Therefore, the base portion 14 of the adjuster main body 11, the pair of side walls 15R and 15L, the pair of connecting portions 16F and 16B, and the lid body 13 attached to the substantially rectangular opening portion 17 are formed along the front and rear directions of the adjuster main body 11.

Further, the front end portions of the side walls 15R and 15L which extend forward from the base portion 14 are connected to each other by the belt mounting rod 19, and one shoulder strap is attached to the belt mounting rod 19.

As shown in Fig. 4 (b) to Fig. 6, a support wall 20 is formed on the inner wall surfaces of the pair of side walls 15R, 15L, and the portion of the support wall 20 which is adjacent to the base portion 14 of the adjuster main body 11 is formed to protrude inward. Thicker. In the support wall 20, a curved support surface 21 for supporting the rocking shaft portion 32 of the locking member 12 to be described later is opened upward and is formed in a substantially U-shaped groove shape (see also FIG. 12(b)). Further, the support wall 20 which is lower than the support surface 21 is formed with an inclined surface 23 which is inclined so as to gradually become thicker as it goes toward the support surface 21, that is, upward.

A portion in which the base portion 14 of the support surface 21 is formed in the vertical direction is formed with an opening hole 22 so as to face the support surface 21 in the vertical direction. The opening hole 22 is formed to allow a mold (not shown) for forming the support surface 21 to be inserted.

Further, in the base portion 14 of the adaptor main body 11, a curved surface portion 24 that is recessed toward the lower side of the adjuster main body 11 is formed at a position rearward of the support surface 21, and a through-base portion 14 is formed substantially at the center of the curved surface portion 24. Opening 25 . The opening portion 25 is arranged in a protruding manner as will be described later. The operating portion 34 of the locking member 12. In this manner, even when the curved surface portion 24 is searched by the finger without visually recognizing the belt adjusting device 10, the operation portion 34 protruding from the opening portion 25 can be easily recognized.

As shown in FIG. 2 and FIG. 3, in the adjuster main body 11, a pair of elastic portions 26 are integrally formed at the base portion 14 of the adjuster main body 11 at a position forward of the support surface 21, and the pair of spring pressures are provided. The portion 26 protrudes toward the belt insertion hole 18 inside the adjuster main body 11.

The biasing portion 26 is formed in a plate-like portion that is bent so as to be able to abut against the locking member 12 to be described later, and is elastically deformable in the vertical direction for applying the locking biasing force to the locking member 12. The elastic portion 26 is formed in a cantilever shape extending inward in the width direction from the pair of side walls 15R and 15L. Therefore, the elastic body portion 21 can be formed to be long without increasing the size in the front-rear direction. As a result, the spring constant is reduced, and the change in the operating force when the locking member 12 is operated is reduced, and the operational feeling can be improved. In the base portion 14 corresponding to the biasing portion 26, a long hole 27 is formed so as to face the entire elastic pressing portion 26 from above, and the long hole 27 is formed so that a mold (not shown) for forming the biasing portion 26 can be inserted. .

As shown in FIGS. 7 to 9, the locking member 12 is provided with a plate-like portion 31 extending in the longitudinal direction (front-rear direction) and a rocking portion 31 supported by the support surface 21 of the adjusting body 11 The cylindrical pair of rocking shaft portions 32 are formed of synthetic resin. The one end side (front side) of the plate-shaped portion 31 of the pair of rocking shaft portions 32 is provided with a locking portion 33 that can be locked to the locking groove 3 of the rack 4, and the other end side (rear side) An operation unit 34 is provided.

The plate portion 31 has a pair of arms 38 extending in the left-right direction, and the pair of rocking shaft portions 32 are formed to protrude upward from the upper surface of the arm portion 38 and are biased upward with respect to the plate portion 31. Specifically, as shown in FIG. 9 , the connection line between the distal end P of the locking portion 33 and the end portion 36 a on the other end side of the surface 36 on the opposite side of the operation portion 34 is an extension line L. A line perpendicular to the extension line L and passing through the axis O of the shaft portion 32 is set as a vertical line V. At this time, the axis O of the pair of rocking shaft portions 32 is offset toward the upper surface 39 side of the plate portion 31 from the intermediate point O' of the thickness of the plate portion 31 at the position along the vertical line V.

In addition, the locking member 12 is attached to the adjuster main body 11 so as to intersect the belt body 1 at one end side of the rocking shaft portion 32 in the insertion direction of the belt body 1 (see FIG. 11). . Therefore, when the locking member 12 is rocked about the axis O of the rocking shaft portion 32 biased toward the upper surface 39 side of the plate portion 31, the end portion 34a of the operating portion 34 is centered on the axis O The arc t moves.

On the other hand, the axis of the rocking shaft portion 32 is not biased toward the upper surface 39 side of the plate portion 31, for example, when the intermediate portion O' of the thickness of the plate member 31 is shaken, the end portion of the operating portion 34 34a will move along an arc t' centered on O'. Therefore, when the axial center O of the pair of rocking shaft portions 32 is biased toward the upper surface 39 side of the plate-like portion 31, the operation portion 34 is caused to swing the end portion 34a in the insertion direction of the belt body 1. When the shaft portion 32 is moved while being pressed, the locking portion 12 is pivoted about the intermediate portion O' of the thickness, and the operation portion 34 is inserted into the belt 1 at the end portion 34a. Moving away from the shaft The direction of 32 is moved while pressing. By biasing the axial center O of the pair of rocking shaft portions 32 toward the upper surface 39 side of the plate-like portion 31, the operation portion 34 can be operated while moving the end portion 34a toward the swing shaft portion 32 side. The sense of operation is improved.

As shown in Fig. 8, the end faces of the pair of rocking shaft portions 32 are inclined faces 35 which are inclined such that the interval between the end faces is gradually narrowed as going upward. When the locking member 12 is assembled to the adjuster main body 11, the locking member is slidably attached to the inclined surface 35 of the pair of rocking shaft portions 32 and the inclined surface 23 provided on the support wall 20 of the adjuster main body 11 12 presses upwards to make assembly easier.

Further, since the axis O of the pair of rocking shaft portions 32 is offset toward the upper surface 39 side of the plate portion 31, the support of the pair of rocking shaft portions 32 can be supported by an offset amount as shown in Fig. 6 . The wall 20 is disposed on the side of the base portion 14 of the adjuster main body 11. As described above, since the support wall 20 and the shoulder belt 1 do not easily interfere with each other, the shoulder belt 1 can be disposed close to the locking member 12, and the thickness of the belt adjusting device 10 can be reduced.

As shown in FIG. 9 , the locking member 12 has a first lower surface 36 that is formed to be substantially flat from the end portion 36 a on the other end side toward the locking portion 33 , and a side on the locking portion 33 side of the first lower surface 36 . The second lower surface 37 which is continuous and curved upward with respect to the first lower surface 36 (on the upper surface 39 side of the plate portion 31) is formed. The locking portion 33 is formed to protrude downward from the second lower surface 37 (on the shoulder belt 1 side), and the front end P of the locking portion 33 is located on the extension line L' of the first lower surface 36. Further, the front end P of the locking portion 33 can be located on the second lower surface 37 side than the extension line L' of the first lower surface 36. In addition, In FIG. 9, the extension line L connecting the front end P of the locking portion 33 and the back surface of the operation portion 34, and the extension line L' of the lower surface 36 are the same in the present embodiment, but the locking portion 33 is The position of the front end P is not limited to this.

When the operation portion 34 is pressed and the locking of the locking portion 33 and the shoulder belt 1 is released, the first lower surface 36 of the locking member 12 becomes the surface of the shoulder belt 1 as shown by a dotted line in FIG. Further, since the locking member 12 does not protrude from the first lower surface 36 toward the shoulder belt 1 side, the shoulder belt 1 can be disposed at a position close to the locking member 12. Therefore, it is possible to reduce the thickness of the belt adjusting device 10.

Further, as shown in FIG. 9, the locking member 12 is set such that the shortest distance between the axis O of the rocking shaft portion 32 and the front end P of the locking portion 33, that is, the first distance L1 is larger than the rocking shaft portion 32. The shortest distance between the axis O and the end portion 34a of the operation portion 34, that is, the second distance L2 is shorter. In this way, the stroke of the operation portion 34 for releasing the locking of the locking portion 33 and the shoulder belt 1 can be increased, and an erroneous operation caused by the contact of the clothes or the like with the operation portion 34 can be prevented.

When the locking member 12 is assembled to the adjuster main body 11, the locking member 12 is inserted into the adjuster main body 11 from the rectangular opening portion 17 formed on the back surface of the adjuster main body 11, as shown in Fig. 12(a). While the inclined surface 35 of the pair of rocking shaft portions 32 is slidably contacted with the inclined surface 23 provided on the support wall 20 of the adjuster main body 11, the pair of rocking shaft portions 32 and the wrist are pressed upward. The portion 38 and the support wall 20 are elastically deformed in the width direction and assembled to the support surface 21 . Thus, as shown in Figure 12(b) As shown, the pair of rocking shaft portions 32 are rotatably supported by the support surface 21 of the adjusting body 11.

5 and 8, since the longest width W1 of the pair of rocking shaft portions 32 is formed to be longer than the shortest width W2 of the support wall 20, the locking member 12 does not fall off from the adjuster main body 11 after assembly.

At the same time, the cantilever-shaped elastic portion 26 extending inward in the width direction from the side walls 15R and 15L of the adjuster main body 11 abuts against the plate portion on the side of the locking portion 33 (front side) from the rocking shaft portion 32. On the upper surface of the 31, the locking portion 33 of the locking member 12 is rotated in the direction in which the shoulder strap 1 is locked by the elastic pressure of the biasing portion 26. At this time, the upper surface of the plate-like portion 31 on the side of the operation portion 34 abuts against the edge portion 25a of the rocking shaft portion defining the base portion 14 of the opening portion 25, thereby restricting the swinging range of the locking member 12 (the locking portion 33 is The direction of the locking groove 3 is shaken).

10 is a perspective view of a lid body, the lid body 13 is provided with a plate portion 41 that is slightly curved outward, and a rectangular casing 42 that can be fitted to the rectangular opening portion 17 of the adjuster body 11 is formed on the back surface of the plate portion 41, The engaging leg portion 44 of one of the engaging portions 43 projecting toward both sides in the left-right direction is provided at the front end. The lid body 13 is fitted to the rectangular opening portion 17 of the adjuster main body 11 and the engaging portion 43 of the engaging leg portion 44 is engaged with the engaging groove 28 of the adjuster main body 11 (refer to the drawing). 4(b) and 6) are attached to the adjuster main body 11.

Further, although the lid body 13 is not an essential member of the belt body adjusting device 10, the rectangular opening portion 17 of the adjuster main body 11 is covered so that the inside cannot be seen, and the commercial value of the belt body adjusting device 10 can be improved. In addition, also A logo, a decorative pattern, or the like can be applied to the surface side of the plate portion 41 to enhance the decorative property. Further, when the lid body 13 is not provided, the adapter main body 11 can be replaced by a pair of coupling portions 16F and 16B, and the base portion 14 and the opposite side (back side) end portions of the pair of side walls 15R and 15L can be used by the plate. The parts are connected.

Therefore, the length adjustment of the shoulder belt 1 is performed by pressing the operation portion 34 of the locking member 12 against the elastic pressure of the elastic portion 26, and moving the locking portion 33 in a direction away from the shoulder belt 1. In the state where the length is the appropriate length, the pressing of the operation portion 34 is released, and the locking portion 33 is locked to the locking groove 3 by the elastic pressure of the elastic portion 26, and the shoulder belt 1 and the belt adjusting device 10 are determined. relative position. Thus, the length of the shoulder strap 1 can be adjusted corresponding to the pitch of the locking groove 3, and the length can be easily adjusted.

Further, depending on the elastic pressure of the biasing portion 26, the degree of engagement between the locking portion 33 and the locking groove 3, the locking portion 33 can be pushed up by the inclined surface 3a of the rack 4, and the shoulder strap 1 can be inserted. The belt insertion hole 18 of the belt adjusting device 10 is adjusted in length.

As described above, the belt body adjusting device 10 according to the present embodiment includes the adjuster main body 11 and the locking member 12, and the base portion 14 of the adjuster main body 11 is formed with an opening for allowing the operation portion 34 of the locking member 12 to protrude. Since the portion 25 is adjusted, the position of the operation portion 34 can be surely recognized without being visually recognized, and the operability can be improved.

Further, the locking member 12 restricts the rocking in the direction of the locking groove 3 by the edge portion 25a of the base portion 14 for defining the rocking shaft portion of the opening portion 25, so that even if the adjusting body main body 11 is not shouldered With 1 plug In the open state, the locking member 12 can still be stably held.

Further, a curved surface portion 24 that is recessed toward the opening portion 25 is formed around the opening portion 25, and the opening portion 25 is located at a position recessed from the surface of the base portion 14, so that the operation portion 34 does not largely protrude from the surface of the base portion 14, and Preventing the operation portion 34 from being accidentally pressed causes the locking of the shoulder belt 1 to be accidentally released. Further, even if the amount of protrusion of the operation portion 34 from the opening portion 25 is small, the stroke of the operation portion 34 can be obtained, and the size can be reduced.

Further, a support wall 20 is formed to protrude inwardly on the pair of side walls 15R, 15L, and the support wall 20 forms a support surface 21 for supporting the rocking shaft portion 32, so that it is not necessary to provide other parts, and the adjuster main body 11 is used. The number of parts can be reduced by supporting the locking member 12. Further, the rocking shaft portion 32 can be shortened, and the rigidity of the locking member 12 can be improved.

Further, since the end faces 35 of the pair of rocking shaft portions 32 are inclined, and the support wall 20 has the inclined surface 23 which is slidably coupled to the inclined end surface 35 of the rocking shaft portion 32, the end face of the rocking shaft portion 32 is allowed to be rocked. Since the 35 is pressed while being slidably attached to the inclined surface 23 of the support wall 20, the assembly of the locking member 12 is facilitated, and the rocking shaft portion 32 can be supported by the support surface 21 of the adjuster main body 11.

Further, the locking member 12 includes a plate-like portion 31 extending between the locking portion 33 and the operation portion 34, and the front end P of the locking portion 33 and the surface 36 opposite to the operation portion 34 are provided in a side view. The connecting line of the end portion 36a on the one end side is an extension line L, and the axis of the pair of rocking shaft portions 32 when the line perpendicular to the extension line L and the axis O of the rocking shaft portion 32 is set to the vertical line V Heart O, compared to the plate portion at the position along the vertical line V The intermediate point O' of the thickness of the portion 31 is further offset toward the upper surface 39 side of the plate portion 31. Therefore, the support wall 20 can be disposed on the side of the base portion 14 of the adjuster main body 11 with an offset amount. As described above, since the support wall 20 and the shoulder belt 1 are less likely to interfere, the shoulder belt 1 can be placed close to the locking member 12, and the belt adjusting device 10 can be made thinner.

Further, the locking member 12 includes a plate-like portion 31 extending between the locking portion 33 and the operation portion 34, and the front end P of the locking portion 33 and the surface 36 on the opposite side to the operation portion 34 are viewed from a side view.
