Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement in a lever connected to the tip of a thread fed out from an ink pot, a thread tensioning device, or the like.

[Conventional technology]

As shown in FIG. 7, a conventionally well-known lever is made by protruding and fixing a stopper c to the bottom surface b of a suitably pin-shaped lever body a made of a material such as plastic. The thread e is looped around an annular groove d formed on the side surface of the main body a and then tied.

[Problem that the invention attempts to solve]

This lever is used, for example, by being temporarily attached to a member such as wood at the construction site of various buildings, but since the thread e is tied directly to the thread e (Due to frequent use, the part up to about 30 cm from the lever is often cut.) In rare cases, the stopper needle c breaks and the lever needs to be replaced.
It is necessary to untie the thread e from the main body a and then tie it again, and it has been desired to eliminate this complexity.

[Means for solving problems]

In view of the above points, the present invention aims to provide a lever that allows threads to be attached and detached with one touch.For this purpose, a recess into which a thread knot is inserted is provided on the side of the lever body, which is equipped with a stopper at the lower end. and an engagement groove for engaging and guiding the thread extending from the knot from the bottom of the recess to the side surface of the main body.

[Effect]

When connecting the threads to the above-mentioned lever,
A knot is tied at the tip of a certain caulking thread, and after fitting the knot into the recess, the thread is extended along the engagement groove toward the stop needle, and is wrapped around the proximal end of the stop needle once or twice. So, there is no direct connection to Karuko itself.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 4, reference numeral 1 denotes a main body made of plastic with a stopper 8 inserted into its lower end, which has an approximately flat plate-shaped upper part 2, an approximately disc-shaped central part 3, and an approximately inverted conical shape. It is formed by integrally vulcanizing and molding the lower part 4 of the. A recess 5 is formed at the lower end of one surface of the upper part 2, and an engaging groove 6 and a guide groove 7 are formed from the lower end of the recess 5 through the central part 3 to the lower end of the lower part 4. has been done. The groove widths of the engagement groove 6 and the guide groove 7 are approximately the same as the thickness of the thread, and when the thread is pulled downward, the thread knot slips out downward from the engagement groove 6 in the central part 3. It is configured so that it does not.

When connecting the thread 9 to the above-mentioned lever,
As mentioned above, tie knot 1 at the end of thread 9 in advance.
0, insert the knot 10 into the recess 5 (Fig. 5), engage the thread 9 into the engagement groove 6 while pulling it slightly downward, and then insert it into the guide groove 7. At the same time, it is wrapped around the base end of the stopper needle 8 once or twice (Fig. 6), and when the thread 9 is released,
On the contrary, it is only necessary to unwind it from the stopper needle 8 and pull it out in the direction to remove it from the guide groove 7, the engagement groove 6, and the recess 5.

[Effects of the invention] As explained above, the karuko of the present invention has a recess in which a thread knot is inserted in the side surface of the karuko body, which is equipped with a stopper at the lower end, and the thread is threaded from the recess to the side surface of the main body. It is provided with an engagement groove for engaging and guiding the threads, and the threads can be easily connected and released without directly tying them.

Claims (1)

[Scope of utility model registration request] A recess into which a thread knot connected to the recess is inserted is provided on the side surface of the lever main body having a stopper at the lower end, and an engagement groove extending from the bottom of the recess to the side surface of the main body engages and guides the thread extending from the knot. Karuko is characterized by the following.
