DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a size adjusting slider used to adjust the length of a shoulder band of a bag, the circumference of a head of a hat, and the waist size of pants.

[0002]

2. Description of the Related Art A conventional size adjusting slider of this type is disclosed in Japanese Utility Model Laid-Open Publication No. 63-27134, etc. Used in combination with a flexible band with a rack-shaped tooth on one side raised at a predetermined pitch, fixed to a part of the object requiring size adjustment such as waist size and formed with a free end. An operating body having a locking claw formed at a distal end thereof is swingably supported by a swinging shaft on which a coil spring is wound on side plates formed on both sides of a fixing bottom plate. The configuration is such that the locking claws are pressed against the tooth body forming surface and locked to the tooth body by the action of coiling.

The above-mentioned conventional size adjusting slider comprises four parts: a fixing bottom plate having a side plate standing up, an operation plate, a swing shaft for swinging the operation plate, and a sprung wound around the swing shaft. For this reason, the production and assembly of parts is troublesome, and there is a problem to be solved in that the coil spring is easily broken and the size adjustment and fixing function is lost at an early stage. Size adjustment tool (size adjustment slider) disclosed by JP-A-275011
Was invented.

The size adjusting slider is formed by bending a locking claw at a front end and bending a rear end of the slider in the same direction as the locking claw, so that a flexible band is used in combination with the folded front end. An operating plate made of a metal spring member integrally formed with a sprocket body portion that comes into contact between the toothed bodies of the above is swingable on side plates formed upright on both sides of a fixing claw or a fixing bottom plate having a fixing hole. The structure is designed to reduce the number of parts, thereby increasing the efficiency of production and assembly work, and eliminating the use of coil breakage with many breakage, ensuring the durability of the size adjustment function. It is.

[0005]

However, the conventional size-adjusting slider has a reduced number of parts, a more efficient manufacturing and assembling work, and a more durable size-adjusting function than the conventional size-adjusting slider. Despite ensuring the resilience, since the elastic member is provided with a resilient force in place of the coil splicing in the sprung body that has the rear end of the operation plate turned in the same direction as the locking claw, the folded portion is provided. Insufficient durability due to the weakness of the wire and the breakage in a relatively short period of time, the increase in the amount of material used, the increase in weight, and the difficulty in folding back the folded body compared to bending Therefore, a problem to be solved has been found in that the production cost, material cost, distribution cost, and the like are increased.

The present invention eliminates the loss of the size adjustment and fixing function due to the breakage of the coiled or folded strip, improves the durability over a long period of time, simplifies the manufacture and assembly of parts, and improves the quality of the material. An object of the present invention is to provide an inexpensive size-adjusting slider that achieves cost savings associated with savings and weight.
