Abstract

[Problem] To provide an adjuster that can operate within a certain thickness range and can be made low-profile. [Solution] The device includes a movement range restricting unit that restricts the range of relative movement of the second member with respect to the first member, and a positioning structure for holding the second member in either a first position or a second position in a second direction, wherein the first position is a 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 through the alignment hole is maintained, and the second position is a state in which the tip is exposed to the outside and the fixing pin can be removed from the alignment hole, and the positioning structure includes two pairs of engagement recesses provided on the surface of a pair of first rails at positions corresponding to each other in the first direction, and a pair of leaf springs provided on the second member at positions corresponding to each other in the second direction, each having a portion that protrudes toward the holding space side.

With the pair of first locking portions and the pair of second locking portions engaged with each other, the pair of first rails and the pair of second rails are engaged with each other, thereby guiding the second member to the first member so that it can move relative to the first and second directions, and a holding space is formed between the first member and the second member that can hold a strip-shaped object having a plurality of alignment holes so that it can move along the first and second directions, in an adjuster, The adjuster is, A movement range restricting unit that restricts the range of relative movement of the second member with respect to the first member, The relative movement includes a positioning structure for holding the second member at either the first position or the second position in the second direction, The first member is equipped with a fixing pin for fixing the position of the object in the first and second directions by inserting it into one of the plurality of alignment holes of the object placed in the holding space, The first position is a 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 through the alignment hole is maintained, and the second position is a state in which the tip of the fixing pin is exposed to the outside and the fixing pin can be removed from the alignment hole. The positioning structure is The surface of the pair of first rails is provided with two pairs of engagement recesses, each positioned at a location corresponding to the other in the first direction, The second member comprises a pair of leaf springs provided at positions corresponding to each other in the second direction, each having a portion that protrudes toward the holding space, An adjuster characterized in that the pair of leaf springs engage with one of the engagement recesses of any of the two pairs of engagement recesses, thereby holding the second member to the first member in either the first or second position.
  2. 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, The adjuster according to claim 1, wherein when the pair of first rails and the pair of second rails are engaged with each other, the range of relative movement of the second member with respect to the first member is restricted by the engagement of the restricting projection and the restricting recess with respect to each other.
  3. 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 adjuster according to claim 2, wherein 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.
  4. The adjuster according to claim 3, wherein the pair of restricting recesses are each formed on the inner portion of the second rail.
  5. The adjuster according to claim 2, wherein the pair of leaf springs have fixing pieces formed by bending at both ends of the longitudinal direction of the long plate-shaped main body so as to extend in a direction perpendicular to the main body, and the central part of the main body in the longitudinal direction has a curved shape with a convex shape, and each is held in a pair of retaining recesses provided in the second member.
  6. The adjuster according to claim 5, wherein the 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.

Description

This invention relates to an adjustment device used for adjusting the length of belts and straps, and more particularly to an adjustment device used for adjusting the length of belts and straps in bags that are worn around the shoulders or waist, such as waist pouches, shoulder bags, and backpacks. As adjusters and fasteners for adjusting the length of belts and straps (hereinafter referred to as "belts, etc."), for example, the adjuster described in Patent Document 1 and the fastener described in Patent Document 2 have been proposed. The adjuster described in Patent Document 1 is a retaining member whose rear end is rotatable relative to the main body. A fixing portion is provided in the insertion hole on the rear end side to reduce the opening size, and a pressing portion is provided that fits into a holding hole in the main body when the upper part of the main body is closed by the rotation of the retaining member. The belt or other object placed in the storage space is pressed and bent by the pressing portion, and then clamped between the fixing portion and the main body, thereby clamping the belt at the desired position and adjusting its length. The fastener described in Patent Document 2 has an engaging portion that is rotatably supported by a holding portion, and is provided with an elastic member that biases the engaging portion to close relative to the holding portion. The length of the belt is adjusted by passing the engaging projection of the engaging portion through the belt length adjustment hole, which is sandwiched between the holding portion and the engaging portion, when the engaging portion is closed relative to the holding portion.
