Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a string threading tool for inserting a relatively wide elastic or inelastic string into a string threading portion formed on an elastic edge of clothing or the like.

[Prior art and its problems]

A conventional cord threading tool of this kind has a pair of rod-like swinging levers having elastic restoring force integrated at the front end fulcrum part, which are formed so as to gradually separate from each other toward the rear free end. By fitting a sliding ring to the outer periphery of the ring and sliding it toward the free end side, the gripping claws formed at the free ends of both swinging arms are forcibly brought into contact with each other. There is one that is used by gripping the edge of the inserted string. However, in conventional products such as those mentioned above, the swinging lever is formed into a bar shape, so even if only the gripping claws are made wide, the clamping force will simply be dispersed and sufficient clamping force will not be obtained. In some cases, the string inserted between the gripping claws may come off during the insertion operation. For this reason, the width of the gripping claws in conventional products is inevitably 5 mm or less. As a result, when such conventional products are used for relatively wide strings, only a portion of the edge of the string can be gripped, making it impossible to reliably grip and pull the string stably. It was not possible to smoothly insert the string. On the other hand, in order to provide a string threader that can securely hold a wide string, it is conceivable to form the swinging lever to be wide according to the width of the string. If the swinging ring is simply made wide, the diameter of the sliding ring must be increased, which not only makes the appearance unsightly, but also makes it impossible to insert the cord into the string passage or makes it difficult to insert the cord. A problem arises. The present invention aims to solve the above-mentioned problems and provide a string threading tool that can be conveniently used for inserting wide strings.

0, and the pivot body 10 has protruding shafts 11 projecting on both sides thereof, and is freely rotatable in the shaft support holes 13 of a pair of shaft support ears 12 that stand up on both sides of the fixed pieces 4, 24, and 34. It is characterized by being able to pivot by fitting into the

[Embodiments] The present invention will be described in detail below based on illustrated embodiments. In the embodiment shown in FIGS. 1 to 3, a leading part 1 is formed by welding together two metal strips each having a width of 5 mm or more, and a gripping part 2
A fixed piece 4 and a swinging piece 5 constituting the leading part 1 are integrally formed with the leading part 1 by extending the lower plate and the upper plate of the leading part 1, respectively. Further, at the rear ends of each of the fixed piece 4 and the swinging piece 5, pressure contact parts 6 and 7 which cooperate to pinch the string A are formed by winding their respective edges inward. The swinging piece 5 is bent upward at a slight angle at the front, so that the swinging piece 5 is elastically biased so as to gradually move away from the fixed piece 4 in its natural state. The locking means 3 of the gripping part 2 is composed of a pivoting body 10 which is approximately L-shaped in side view and has a pressing part 8 and an operation gripping part 9. A pair of shaft supporting ears 12 erected on both sides
The lower surface of the pressing part 8 is placed in contact with the upper surface of the rocking piece 5 so as to be substantially perpendicular to the rocking piece 5. It is rotated approximately 90 degrees rearward (in the direction of the arrow in FIG. 2), and its lower end, that is, the end of the pressing portion 8, is pressed against the upper surface of the swinging piece 5 at approximately right angles, thereby pressing it toward the fixed piece 4. As a result, the pressure contact portions 6 and 7 of the swinging piece 5 and the fixed piece 4 are forced into pressure contact. At this time, the operating grip part 9 of the pivoting body 10 is brought into overlapping contact with the rear end of the swinging piece 5 in a state of protruding slightly rearward. To release the locking means 3, the rear end portion of the operating grip portion 9 protruding from the rear end of the swinging piece 5 may be grasped to forcibly rotate the pivoting body 10 in the reverse direction. 4 and 5 show another embodiment, in which the fixing piece 24 of the leading part 21 and the gripping part 22 is formed of a single metal strip plate, and the fixing piece 24 is formed from the rear part of the strip plate. The projecting piece 27 provided at the front end of the swinging piece 25 is fitted into the receiving hole 26 formed on the bottom surface of the piece 24, and the side projecting pieces provided on both sides of the front part of the swinging piece 25 are inserted into the receiving hole 26 of the fixed piece 24. The swinging piece 25 is connected to the fixed piece 24 by being hooked to the front side of the shaft support lug 12. Further, at the rear end of the fixed piece 24, a cylindrical member 20 made of an elastic material such as rubber or synthetic resin is provided in the shaft hole on both sides of the fixed piece 24 so that the string S can be clamped. It is attached by fitting and fixing a pair of L-shaped protrusions 28. The swinging piece 25 is configured such that its rear end can be brought into pressure contact with the cylindrical member 20 by rotation of the pivoting body 10. The rest of the structure is the same as that of the above embodiment, and corresponding parts are designated by the same reference numerals. FIGS. 6 and 7 show still another embodiment, in which the leading portion 31 is formed by bending a rigid wire into a substantially U-shape. Further, the fixed piece 34 and the swinging piece 35 of the gripping part 32 are made of two rectangular metal plates.
7 is inserted into a receiving hole 36 of a rising edge 38 connected to the front end of the fixed piece 34, thereby connecting the fixed piece 34 and the swinging piece 35. The leading portion 31 and the gripping portion 32 include the inwardly bent portions 39, 39 connected to both ends of the leading portion 31, and the gripping portion 3.
The fixed piece 34 and the swinging piece 35 of No. 2 are connected by forcefully fitting and locking the inner side of the rising edge 38 of the swinging piece 35 from the gap between the front ends thereof using elasticity. It is. The rest of the structure is the same as that of the first embodiment, and corresponding parts are designated by the same reference numerals as in the first embodiment. Although not shown in the drawings, the fixed piece and swinging piece of the leading part and the gripping part are constructed from a single metal band-shaped plate, and the band-shaped plates are folded and overlapped at the center, and are mutually connected except for the rear part. It can also be formed by welding to and bending one of the rear parts in the direction of separation.

[Effect of the idea]

Since the present invention has the above-mentioned configuration, sufficient gripping force can be exerted even if the width of the gripping parts 2, 22, and 32 is made wider than 5 mm depending on the width of the string. Moreover, unlike conventional products that have a sliding ring fitted around the outer periphery of the rocking piece, part of the outer periphery is too large, making it difficult to insert it into the string passage part of clothing, etc. There is no risk of fraying, the ends of even a relatively wide string can be firmly clamped over the entire width and the string can be pulled stably, and the insertion operation can be performed smoothly and reliably. Furthermore, the gripping operation of the string S can be easily performed by simply rotating the pivoting body 10 in a predetermined direction.As long as the pivoting body 10 is not forcibly rotated in the opposite direction,
Since the string 5 will not expand inadvertently, the string S will not come off from the gripping portion during the insertion operation, and the string S can be securely clamped and held.
