Description

Technical Field

[0001] The present invention relates to a regulator used for adjusting the length of a belt or a strap, and particularly to a regulator used for adjusting the length of a belt or a strap in a bag that is used by hanging the belt or the strap around the shoulder or the waist, such as a waist pouch, a shoulder bag, or a backpack.

Background Art

[0002] As a regulator and a fastener for adjusting the length of a belt or a strap (hereinafter referred to as a belt or the like), for example, the regulator described in Patent Document 1 and the fastener described in Patent Document 2 have been proposed. In the regulator described in Patent Document 1, in a pressing member whose rear end portion is rotatable with respect to a main body, a fixing portion for reducing the opening size is provided in an insertion hole on the rear end portion side, and when the upper portion of the main body is closed by rotating the pressing member, a pressing portion that enters a holding hole portion provided in the main body portion is provided. A belt or other object disposed in the accommodation space is pressed by the pressing portion and bent, and then sandwiched between the fixing portion and the main body, thereby sandwiching the belt at a desired position and adjusting its length.

[0003] In the fastener described in Patent Document 2, an engaging portion is rotatably supported with respect to a holding portion, and an elastic member that biases the engaging portion to close with respect to the holding portion is provided. When the engaging portion is closed with respect to the holding portion with respect to a belt length adjustment hole sandwiched between the holding portion and the engaging portion, the length of the belt is adjusted by passing an engaging protrusion provided in the engaging portion therethrough.

Summary of the Invention

[0005] However, both the adjuster described in Patent Document 1 and the fastener described in Patent Document 2 have a structure in which the retaining member or engaging part rotates and pulls up to release the belt's hold. Therefore, a certain size is required in the thickness direction of the belt, making it difficult to reduce the profile and potentially affecting the aesthetics due to its presence. Furthermore, there was a problem that the belt's hold could be released if the retaining member or engaging part was pulled up unintentionally by the user or others touching it.

[0006] The adjustment device described in Patent Document 1 had the problem that the belt would be damaged because it was deformed and clamped by the fixing part and the pressing part.

[0007] In the fastener described in Patent Document 2, since the elastic member is located inside the engaging portion, when the elasticity of the elastic member deteriorates due to long-term use, the entire fastener must be disassembled to replace the elastic member. Furthermore, because the engaging projection is located inside the engaging portion, it is difficult to visually confirm the positional relationship between the engaging projection and the belt length adjustment hole, which could make the alignment operation complicated.

[0008] Therefore, the present invention aims to provide an adjuster that can operate within a certain thickness range and can be made low-profile. Furthermore, it aims to provide an adjuster that can hold belts, etc., while suppressing damage to them, and that can be easily disassembled and replaced during inspection and repair in long-term use. [Means for solving the problem]

[0009] To solve the above problems, the adjuster of the present invention comprises a first member having a pair of first rails extending linearly in a first direction parallel to each other at a first base, and a second member having a pair of second rails extending linearly in a second direction parallel to each other at a second base, wherein the pair of first rails each have a pair of first locking parts, and the pair of second rails each have a pair of second locking parts, and the pair of first locking parts and the pair of second locking parts engage with each other so that the first member and the second member face each other An adjuster comprising a pair of first rails and a pair of second rails that are engaged with each other in a state where they are restricted from moving apart in the direction, and with a pair of first locking parts and a pair of second locking parts engaged with each other, the second member is guided by the first member and made movable along the first and second directions, and a holding space is formed between the first member and the second member that has a plurality of alignment holes and can hold a strip-shaped object movable along the first and second directions, wherein the adjuster is relative to the first member The device comprises a movement range restricting unit that restricts the range of relative movement of the second member, and a positioning structure for holding the second member at either a first position or a second position in a second direction during relative movement, wherein the first member is equipped with a fixing pin for fixing the position of an object in the first and second directions by inserting it into one of a plurality of alignment holes of the object placed in the holding space, the first position is the position in which the tip of the fixing pin is close to the second member and the state in which the fixing pin is inserted into the alignment hole is maintained, and the second position is the position in which the tip of the fixing pin The positioning structure is characterized by the fact that the part is exposed to the outside and the fixing pin can be removed from the alignment hole, and the positioning structure comprises two pairs of engagement recesses provided on the surface of a pair of first rails at positions corresponding to each other in a first direction, and a pair of leaf springs provided on the second member at positions corresponding to each other in a second direction, with portions protruding toward the holding space side, and the second member is held by the first member at either the first position or the second position by the pair of leaf springs engaging with one pair of engagement recesses of any of the two pairs of engagement recesses.

[0010] In the adjustment device of the present invention, the movement range restricting portion comprises a restricting projection provided on one of the first member and the second member and a restricting recess provided on the other member, and it is preferable that when the pair of first rails and the pair of second rails are engaged with each other, the restricting projection and the restricting recess engage with each other, thereby restricting the range of relative movement of the second member with respect to the first member.

[0011] In the adjuster of the present invention, it is preferable that the pair of first rails are positioned inside the pair of second rails when the pair of first rails and the pair of second rails are engaged with each other, the pair of first locking portions are formed by bending the respective ends of the pair of first rails outward, and the pair of second locking portions are formed by bending the respective ends of the pair of second rails inward.

[0012] In the adjuster of the present invention, it is preferable that the pair of regulating recesses are formed on the inner portion of the second rail.

[0013] In the adjuster of the present invention, it is preferable that the pair of leaf springs have fixing pieces formed by bending at both ends in the longitudinal direction of the long plate-shaped main body so as to extend in a direction perpendicular to the main body, and that the central part in the longitudinal direction of the main body has a curved plate shape that is convex, and that they are each held in a pair of retaining recesses provided in the second member.

[0014] In the adjuster of the present invention, it is preferable that a pair of retaining recesses are provided on the second base and are located in a range that overlaps with a portion of each of the pair of restricting recesses in a plan view. [Effects of the Invention]

[0015] According to the present invention, by reducing the profile, the amount of protrusion in the thickness direction when attached to a belt or strap can be suppressed, thereby reducing the impact on the aesthetics of the belt, strap, and the bag to which they are attached, and reducing the possibility that the user may unintentionally release the length adjustment. Furthermore, since the length adjustment is performed by inserting a fixing pin through the alignment hole of the belt, damage to the belt can be suppressed. By releasing the restriction by the movement range restricting part, the first member and the second member can be separated, making it easy to access each component, including the leaf spring held in the retaining recess, and facilitating inspection and replacement during maintenance.

Mode for Carrying Out the Invention

[0017] Hereinafter, the adjuster according to the embodiment of the present invention will be described in detail with reference to the drawings. Each figure shows XYZ coordinates as reference coordinates. In the following explanation, for the first member 10, the X11-X12 direction is referred to as the front-back direction, the Y11-Y12 direction as the left-right direction, and the Z11-Z12 direction as the up-down direction. For the second member 20, the X21-X22 direction is referred to as the front-back direction, the Y21-Y22 direction as the left-right direction, and the Z21-Z22 direction as the up-down direction. For the adjuster 40 which engages the first member 10 and the second member 20 with each other, the X11-X12 direction, Y11-Y12 direction, and Z11-Z12 direction as the first direction in the first member 10 coincide with the X21-X22 direction, Y21-Y22 direction, and Z21-Z22 direction as the second direction in the second member 20, respectively, so the coordinates used for the first member 10 are used. For the first member 10, the X11-X12 direction and the Y11-Y12 direction are perpendicular to each other, and the XY plane containing these directions is perpendicular to the Z11-Z12 direction. Also, the view from the top (Z11 side) to the bottom (Z12 side) is sometimes called a plan view. The same applies to the coordinates for the second member 20.

[0018] As shown in Figures 1 to 5, the adjuster 40 according to the first embodiment comprises a first member 10, a second member 20, and a pair of leaf springs 31 and 32 (Figures 4 and 5). As shown in Figures 1, 3, and 5, the first member 10 and the second member 20 are engaged with each other in a manner that restricts them from moving apart in opposing directions, i.e., the Z11-Z12 direction. In this state, the second member 20 is guided by the first member 10 and made relatively movable along the X11-X12 direction, which is the first direction.

[0019] The first member 10 and the second member 20 are manufactured by molding metal, alloy, or synthetic resin, with the material selected based on strength and design. Examples of materials that make up the first member 10 and the second member 20 include brass, titanium, stainless steel, synthetic resin, copper, iron, aluminum, titanium alloy, and aluminum alloy. The detailed configuration of each component is described below.

[0020] <First member 10> As shown in Figure 2(b) or Figure 4, the first member 10 is provided with a first base portion 10a that is rectangular in plan view and extends in the XY plane, on which a pair of first rails 11 and 12 extend linearly parallel to each other along the front-to-back direction X11-X12, which is the first direction. The width of the pair of first rails 11 and 12 in the left-to-right direction Y11-Y12 corresponds to the width of the belt S, which is a strip-shaped object held by the adjuster 40, thereby making it possible to accommodate the belt S between the pair of first rails 11 and 12. The first base portion 10a is formed with a greater thickness in the region outside the pair of first rails 11 and 12 than in the region inside.

[0021] Here, the object whose length is adjusted by the adjuster 40 is a strip-shaped body having alignment holes formed at regular intervals along its longitudinal direction, such as a belt or strap used for a handbag, backpack, or clothing.

[0022] As shown in Figure 6, the pair of first rails 11 and 12 have shapes that are symmetrical with respect to the center line 10AX in the left-right direction Y11-Y12. As shown in Figures 2(b) and 4, the pair of first rails 11 and 12 have upper ends that extend upward from the first base 10a, respectively, which are bent outward in the left-right direction Y11-Y12 to form a pair of first locking portions 11a and 12a.

[0023] As shown in Figure 2(b), the first base portion 10a is provided with a fixing pin 13 that extends upward at the front portion, located in the center of the left-right direction Y11-Y12. This fixing pin 13 has an outer diameter that allows it to be inserted into any of the alignment holes S1, S2, or S3 of the belt S, which is the object being adjusted, and is inserted into the holding space 40a (Figure 5) of the adjuster 40. The length of the fixing pin 13 extending in the vertical direction Z11-Z12 is such that when the first member 10 and the second member 20 are engaged with each other, the tip of the fixing pin is close to the second member 20, and the distance between the tip of the fixing pin 13 and the second member 20 is smaller than the thickness of the belt S. Therefore, when the first member 10 and the second member 20 are engaged with each other and the fixing pin 13 is positioned above the second member 20, the state in which the belt S is inserted into the alignment hole is maintained.

[0024] As shown in Figures 2(b), 4, and 5, a pair of through holes 14a and 14b are provided on the outer portions of the pair of first rails 11 and 12, respectively, penetrating the first base 10a in the thickness direction (Z11-Z12 direction). As shown in Figure 4, a pair of screws 15a and 15b are screwed into these through holes 14a and 14b from the bottom surface of the first base 10a. As shown in Figure 5, the tips 16a and 16b of the screwed pair of screws 15a and 15b are exposed from the outer portions of the pair of first rails 11 and 12 through the pair of through holes 14a and 14b, and engage with a pair of regulating recesses 23 and 24 of the second member 20 which is engaged with the first member 10. The pair of through holes 14a and 14b are located approximately midway between the pair of front-side engagement recesses 111 and 121 and the pair of rear-side engagement recesses 112 and 122 in the front-rear direction.

[0025] As shown in Figure 2(b), the upper surface of the left first rail 11 is provided with two downwardly recessed engagement recesses 111 and 112 at two positions in the front-rear direction X11-X12, and the upper surface of the right first rail 12 is also provided with two engagement recesses 121 and 122 at positions corresponding to the engagement recesses 111 and 112 in the front-rear direction X11-X12. This forms a pair of engagement recesses 111 and 121 in the left-right direction Y11-Y12, and another pair of engagement recesses 112 and 122. These two pairs of engagement recesses 111, 112, 121, and 122 are identical in shape and are recessed so that the surfaces of the leaf springs 31 and 32 held in the retaining recesses 25 and 26 (Figure 8) engage with and are held. In Figure 8, the leaf springs 31 and 32 inserted into the retaining recesses 25 and 26 are virtually shown with dashed lines.

[0026] <Second component 20> As shown in Figure 2(a) or Figure 4, the second member 20 has a second base portion 20a that is rectangular in plan view and extends in the XY plane. A pair of second rails 21 and 22 are provided on the bottom surface of this second base portion 20a, which is rectangular in plan view and parallel to each other, along the front-rear direction X21-X12, which is the second direction. Here, the second base portion 20a is a rectangular plate with a uniform thickness, and its plan view shape is the same as that of the first base portion 10a.

[0027] As shown in Figure 8, the pair of second rails 21 and 22 have shapes that are symmetrical with respect to the center line 20AX (Figure 8) in the left-right direction Y21-Y22, and as shown in Figure 2(a), the lower ends of the second base portion 20a are each bent inward in the left-right direction Y21-Y22, forming a pair of second locking portions 21a and 22a. When the first member 10 and the second member 20 are engaged with each other, this pair of second locking portions 21a and 22a engage with the pair of first locking portions 11a and 12a of the first member 10, respectively, thereby allowing the second member 20 to move relative to the first member 10 along the front-rear direction X21-X22, which coincides with the front-rear direction X11-X12.

[0028] When the first member 10 and the second member 20 are engaged with each other, a holding space 40a is formed, surrounded by the first base portion 10a, the second base portion 20a, and the pair of first rails 11 and 12, as shown in Figure 5. This holding space 40a has a size that allows the belt S, as the object, to be inserted and held in the left-right direction Y11-Y12 and the up-down direction Z11-Z12.

[0029] As shown in Figures 2, 5, and 8, a restricting recess 23 is provided in the lower part of the left-side second rail 21, in the inner portion in the left-right direction Y21-Y22, so as to recess the second locking portion 21a. This restricting recess 23 is recessed, leaving both ends of the second locking portion 21a in the front-rear direction X21-X22, and is open at the bottom (Z22 direction). The height of the restricting recess 23 in the vertical direction Z21-Z22 is such that the tip 16a of the screw 15a screwed into the insertion hole 14a can be positioned when the first member 10 and the second member 20 are engaged with each other.

[0030] The second rail 22 on the right side is also provided with a restrictive recess 24 that has a shape symmetrical to the restrictive recess 23 with respect to the center line 20AX. Therefore, a pair of restrictive recesses 23 and 24 are provided on each of the pair of second rails 21 and 22.

[0031] The second base portion 20a is provided with a pair of retaining recesses 25 and 26, each having an inner surface shape corresponding to the shape of a pair of leaf springs 31 and 32, so as to be able to hold a pair of leaf springs 31 and 32. In the left-right direction Y21-Y22, these retaining recesses 25 and 26 are positioned opposite the pair of first rails 11 and 12 when the first member 10 and the second member 20 are engaged with each other. Furthermore, in the front-rear direction X21-X22, at the first position P1 (Figures 1, 5, 10(a), 11(a), and 14) where the second member 20 overlaps the first member 10 without shifting in a plan view, the retaining recesses 25 and 26 are positioned opposite the pair of engagement recesses 111 and 121.

[0032] As shown in Figures 2 and 8, the pair of restricting recesses 23 and 24 have areas that overlap with the outer portions of the retaining recesses 25 and 26 in the left-right direction Y21-Y22, and these areas are cut out in the up-down direction Z21-Z22. These cutouts serve as a pair of introduction portions 25a and 26a for introducing the pair of leaf springs 31 and 32 from below.

[0033] As shown in Figure 8, when the second member 20 is viewed from below, the four corners of the pair of retaining recesses 25 and 26 each have semicircular auxiliary holes 25b and 26b that are wider in the left-right direction than the width of the pair of leaf springs 31 and 32 into which they are inserted. By inserting a tool or the like into the auxiliary holes 25b and 26b, it becomes possible to easily attach, detach, and adjust the pair of leaf springs 31 and 32.

[0034] <Leaf springs 31, 32> The pair of leaf springs 31 and 32 are formed by press working and have the same plate shape. As shown in Figures 9(a) and (b), the leaf spring 31 has a long plate-shaped main body 31a from which two fixing pieces 31b and 31c extend upward from both ends in the longitudinal direction, and the central part 31d in the longitudinal direction of the main body 31a is curved so as to be convex downward (towards Z22). Furthermore, the two fixing pieces 31b and 31c are bent perpendicular or nearly perpendicular to the surface of the main body 31a and extend upward (towards Z21). The central part 31d is curved by cold working and is elastically deformable to be concave upward (towards Z21) and nearly flat when an external force is applied from below (from the Z22 side), and has the elasticity to return to a shape that is convex downward when the external force is released. The other leaf spring 32 also has a main body 32a, two fixing pieces 32b and 32c, and a central part 32d, as shown in parentheses in Figures 9(a) and (b), similar to the leaf spring 31.

[0035] As shown in Figures 8 and 10(a) and (b), the leaf spring 31 is held in the retaining recess 25 by inserting it into the retaining recess 25 such that the front fixing piece 31b abuts against the front inner surface 25c of the retaining recess 25 and the rear fixing piece 31c abuts against the rear inner surface 25d of the retaining recess 25. Insertion of the leaf spring 31 into the retaining recess 25 is performed as shown in Figure 3, by engaging the first member 10 and the second member 20 with each other and shifting them in the front-rear direction so that the retaining recess 25 is exposed. After this, with the relative positions of the first member 10 and the second member 20 set within the range from the first position P1 (Figure 10(a)) to the second position (Figure 10(b)), a pair of screws 15a and 15b are screwed into a pair of insertion holes 14a and 14b provided in the first member 10. As a result, the tips 16a and 16b of the pair of screws 15a and 15b engage with the pair of restricting recesses 23 and 24, respectively.

[0036] With this holding configuration, even when an external force is applied to the central portion 31d, the elastic force of the leaf spring 31, with its fixing pieces 31b and 31c in contact, maintains contact with the inner surfaces 25c and 25d of the holding recess 25, and the leaf spring 31 is held in the holding recess 25. Similarly to the leaf spring 31, the other leaf spring 32 is held in the holding recess 26 by bringing its front fixing piece 32b into contact with the front inner surface 26c of the holding recess 26 and its rear fixing piece 32c into contact with the rear inner surface 26d of the holding recess 26.

[0037] When the pair of leaf springs 31 and 32 are not in contact with the first member 10 (see Figures 2 and 4), and when they are engaged in either the pair of engagement recesses 111 and 121 or another pair of engagement recesses 112 and 122 (see Figures 5, 10(a) and (b)), the central portions 31d and 32d are convex downwards and protrude toward the holding space 40a.

[0038] On the other hand, when the pair of leaf springs 31 and 32 are in contact with the surfaces of the pair of first rails 11 and 12 other than the engagement recesses 111, 112, 121, and 122, the central portions 31d and 32d of the pair of leaf springs 31 and 32 are subjected to an upward external force due to this contact, causing them to deform flatten in whole or in part, depending on the magnitude of the external force.

[0039] Examples of materials that make up the pair of leaf springs 31 and 32 include phosphor bronze, iron, stainless steel, and brass.

[0040] A pair of leaf springs 31 and 32, and two pairs of engagement recesses 111, 112, 121, and 122 provided on a pair of first rails 11 and 12 respectively, constitute a positioning structure that selectively realizes two positions P1 and P2 as the relative positions of the second member 20 with respect to the first member 10. When the second member 20 is moved relative to the first member 10 in the front-rear direction X11-X12 with respect to the first member 10 while the first member 10 and the second member 20 are engaged with each other, the pair of leaf springs 31 and 32 engage with the pair of engagement recesses 111 and 121 at the first position P1 (Figures 10(a) and 11(a)), and engage with another pair of engagement recesses 112 and 122 at the second position P2 (Figures 10(b) and 11(b)), providing the user with a click sensation when these engagements occur. Then, at each position, the second member 20 can be held with a predetermined holding force based on the elastic force of the pair of leaf springs 31 and 32.

[0041] When the pair of leaf springs 31 and 32 are not engaged in any of the two pairs of engagement recesses 111, 112, 121, and 122, but are in contact with the surfaces of the pair of first rails 11 and 12, the curved shape of the central portions 31d and 32d is deformed into a flattened state. This allows for smooth relative movement of the second member 20 with respect to the first member 10. In contrast, when the pair of leaf springs 31 and 32 are engaged in the pair of engagement recesses 111 and 121, or another pair of engagement recesses 112 and 122, the central portions 31d and 32d of the pair of leaf springs 31 and 32 return to their curved shape and are in contact with the inner surface of the engagement recess, so the engaged state is reliably maintained by their elastic force.

[0042] <Adjustment tool> As shown in Figures 1, 5, and 10(a), when the first member 10 and the second member 20 are engaged, the left-side first locking portion 11a and second locking portion 21a have the upper surface 110a of the first locking portion 11a in contact with the inner surface 210a of the second base portion 20a, as shown in Figure 4. Furthermore, the outer surface 110b of the first locking portion 11a, the bottom surface 110c of the first locking portion 11a, and the outer surface 110d of the first rail 11 extending downward from the bottom surface 110c are in contact with the inner surface 210b of the second rail 21, the upper surface 210c of the second locking portion 21a, and the inner surface 210d of the second locking portion 21a, respectively. Similarly, in the first locking portion 12a and the second locking portion 22a on the right side, as shown in Figure 4, the upper surface 120a of the first locking portion 12a contacts the inner surface 210a of the second base portion 20a. Furthermore, the outer surface 120b of the first locking portion 12a, the bottom surface 120c of the first locking portion 11a, and the outer surface 120d of the first rail 12 extending downward from the bottom surface 120c contact the inner surface 220b of the second rail 22, the upper surface 220c of the second locking portion 22a, and the inner surface 220d of the second locking portion 22a, respectively (see Figure 5).

[0043] Since the surfaces of the pair of first rails 11 and 12 and the pair of first locking parts 11a and 12a, and the pair of second rails 21 and 22 and the pair of second locking parts 21a and 22a are in contact with each other in this manner, the movement of the second member 20 in the vertical direction Z11-Z12 relative to the first member 10 is restricted, while it is able to move along the front-rear direction X11-X12, which is the direction in which the pair of first rails 11 and 12 extend.

[0044] When the first member 10 and the second member 20 are engaged with each other in this manner, the tips 16a and 16b of the pair of screws 15a and 15b, which are screwed into the pair of through holes 14a and 14b respectively, are inserted into the pair of restricting recesses 23 and 24, respectively (see Figures 5, 10(a) and (b)). Therefore, the relative movement of the second member 20 with respect to the first member 10 in the front-rear direction X11-X12 is restricted to a range from a first position P1 (Figures 10(a), 1, and 11(a)) where a pair of leaf springs 31 and 32 engage with a pair of engagement recesses 111 and 121 respectively, and a pair of screws 15a and 15b contact the rear end surfaces 23a and 24a (Figures 8 and 10(a)) of a pair of restricting recesses 23 and 24, to a second position P2 (Figures 10(b), 11(b), 12, and 13) where a pair of leaf springs 31 and 32 engage with a pair of engagement recesses 112 and 122 respectively, and a pair of screws 15a and 15b contact the rear end surfaces 23b and 24b of a pair of restricting recesses 23 and 24. Thus, the pair of screws 15a and 15b as restricting protrusions and the pair of restricting recesses 23 and 24 constitute a movement range restricting section that restricts the range of relative movement of the second member 20 with respect to the first member 10. Since the retaining recesses 25 and 26 are provided in a range that overlaps with the first member 10 in the front-rear direction at the second position P2, the leaf springs 31 and 32 cannot be seen from the outside at the second position P2, thus contributing to a high level of design.

[0045] In this embodiment, a pair of screws 15a and 15b are shown as an example of restricting protrusions, and these engage with a pair of restricting recesses 23 and 24, respectively, thereby restricting the range of relative movement of the second member 20 with respect to the first member 10. However, the shape and configuration of the restricting protrusions and restricting recesses are not limited to these. By providing a restricting protrusion on one of the first member 10 and the second member 20, and a restricting recess on the other of the first member 10 and the second member 20, and engaging the restricting protrusions and restricting recesses with each other, the range of relative movement of the second member 20 with respect to the first member 10 can be restricted. Examples of restricting protrusions include pin members or rivets without helical grooves, and by press-fitting or driving them into the first member 10 and inserting the tip of the pin member or rivet into the restricting recess, the range of relative movement of the second member 20 with respect to the first member 10 can be restricted. By using pin members or rivets, it becomes possible to create a highly aesthetically pleasing structure in which the top or other parts do not protrude from the bottom surface of the first member 10 into which they are press-fitted or driven.

[0046] The first position P1 is the position in which the tip of the fixing pin 13 is close to the second base portion 20a of the second member 20, and the state in which the fixing pin 13 is inserted through one of the alignment holes S1, S2, or S3 of the belt S is maintained. As shown in Figure 12, the second position P2 is the state in which the tip of the fixing pin 13 is exposed to the outside, and the fixing pin 13 can be removed from the alignment hole through which the fixing pin 13 is inserted (S1 in the example shown in Figure 12).

[0047] The length of the belt S using the adjuster 40 is adjusted by sliding the second member 20, which was in the first position P1, backward to the second position P2. At the second position P2, the belt S is bent upward as shown in Figure 13, which allows the fixing pin 13 to be removed from the alignment hole S1. From this state, for example, the belt S can be moved forward to pass the fixing pin 13 through the adjacent alignment hole S2. After passing the belt through the fixing pin 13, the second member 20 is returned to the first position P1 as shown in Figure 14, which allows the alignment hole S2 to be maintained in the position where it is passed through the fixing pin 13.

[0048] As shown in Figure 11(a), the fixing pin 13 is located in front of the pair of engagement recesses 111 and 121 on the front side in the front-rear direction X11-X12. By positioning it in this way, when the second member 20 is moved relative to the second position P2 where the pair of leaf springs 31 and 32 engage with the pair of engagement recesses 112 and 122 on the rear side, the fixing pin 13 is exposed to the outside, and the alignment hole (S1 in the case of Figure 11(b)) can be disengaged from the fixing pin 13 by bending the belt S upward.

[0049] As described above, the above embodiment provides the following effects. (1) The configuration in which the first member 10 and the second member 20 move relative to each other in the front-to-back direction makes it possible to reduce the height, and when attached to a belt or strap, the amount of protrusion in the thickness direction can be reduced, thereby reducing the impact on the design of the belt, strap, and the bag to which they are attached, and reducing the possibility that the user may unintentionally release the length adjustment and fixed state. (2) In a configuration in which the first member 10 and the second member 20 move relative to each other in the front-rear direction, when the length adjustment is completed and the second member 20 is placed in the first position, the first member 10 and the second member 20 have shapes that coincide with each other in the front-rear direction and the left-right direction, so that a compact overall shape can be achieved in these directions as well. (3) The length of the belt S is adjusted by inserting the fixing pins 13 through the alignment holes S1, S2, and S3, thereby minimizing damage to areas of the belt S other than the alignment holes. (4) By simply removing the screws 15a and 15b which serve as movement range restricting parts, the second member 20 can be slid away from the first member 10 and disassembled. This allows easy access to each component, including the leaf springs 31 and 32 held in the retaining recesses 25 and 26, making inspection and replacement during maintenance and other occasions easier.

[0050] In the above embodiment, a pair of engagement recesses 111, 121 for positioning the second member 20 at a first position P1, and another pair of engagement recesses 112, 122 for positioning it at a second position P2 were provided. The spacing between the pair of engagement recesses 111, 121 and the other pair of engagement recesses 112, 122 in the front-rear direction X11-X12 was set based on the spacing between the alignment holes S1, S2, S3 of the belt S. However, the number of pairs of engagement recesses can be three or more. This makes it possible to adjust the length appropriately even for belts with short spacings between alignment holes, and makes it possible to accommodate belts with various spacings.

[0051] In the above embodiment, an example was shown in which a single belt S is held by the fixing pin 13. However, by appropriately adjusting the height of the first rails 11 and 12 in the vertical direction Z11-Z12, the height of the second rails 21 and 22 in the vertical direction Z21-Z22, and the length of the fixing pin 13, it is possible to insert the fixing pin 13 and hold even belts S that are wrapped around or folded over, and adjust their length.

[0052] In the above embodiment, one fixing pin 13 was provided, but the number of fixing pins can be multiple, thereby more securely holding the object. In this configuration, it is preferable to appropriately configure the first member 10 and the second member 20 so that all fixing pins are exposed when adjusting the length of the object.

[0053] In the above embodiment, the leaf springs 31 and 32 were provided with central portions 31d and 32d in the longitudinal center of the main body portions 31a and 32a, which protrude toward the holding space 40a, and which correspond to the engagement recesses 111, 112, 121, and 122. However, the range of the portion protruding toward the holding space 40a is not limited to the range of the central portions 31d and 32d shown in Figures 9(a) and (b), but can be arbitrarily set to a range that can engage with the engagement recesses 111, 112, 121, and 122.

[0054] Furthermore, although the central sections 31d and 32d were formed into a curved shape by cold working, the method of forming the curved shape is not limited to this, and it can also be formed by hot working, for example. Although the present invention has been described with reference to the above embodiments, the present invention is not limited to the above embodiments, and improvements or modifications are possible for the purpose of improvement or within the scope of the spirit of the present invention.
