Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a slider with a stop device for a slide fastener.

(Prior Art) This type of slider is equipped with a locking member that can be automatically returned to the upper part of the slider body by a spring so as to be able to swing up and down. Equipped with a stop claw that plunges inward and a raised part that bends into a chevron shape,
A camshaft installed between the two prongs of the handle and deviated downward is inserted into the raised part. When the handle is raised or reversed, the raised part is raised by the camshaft, and as a result, the raised part is raised. The stop pawl floats up, and when you release your hand from the handle, the repulsive force of the spring causes the pull to fall back to its original state parallel to the top piece, and the stop pawl plunges into the slider body. by the way,
The camshaft of the handle is provided in such a manner that it protrudes further downward from the lower part at the tip of the forked part, so that the strong spring can be easily operated by lightly operating the handle like a ram. Furthermore, the above-mentioned stop pawl generally works as a lock by entering between the engagement teeth of the fastener chain and preventing the slider from sliding, and although it is irregular, the fastener chain remains locked with the stop pawl. It has a ratchet function that slides the slider by applying a strong lateral attraction force to the separating part of the stopper. There are some that apply more pressure.

(Problem to be solved by the invention) When the above-mentioned camshaft-equipped pull is brought down to its original state, or when the slider is slid by the ratchet function, the stop pawl happens to fall into the required position relative to the jamming teeth. In some cases, the stop pawl is lifted up by the fastening tooth and the protrusion remains raised, and at the same time the handle is moved against the slider. It may become twisted, and if the handle twists sideways,
The distal end of the bifurcated part of the handle got stuck in the lower part of the floating raised part, preventing the raised part from returning downward, making it impossible to lock the handle.

This idea is to solve the above problem,
When the slider stops sliding, even if the handle is twisted sideways and the tip of the fork fits under the protrusion of the locking member, it will immediately come off and always provide a reliable locking or ratcheting function. An object of the present invention is to provide a slider with a fastener stop device.

(Means for solving the problem) The solution according to this invention is to attach a handle with a new configuration to a slider body and a locking member similar to those of the conventional one, and the handle has a handle at its tip. In contrast to the configuration in which the camshaft is installed offset to the lower side between the two prongs of the handle, there is a camshaft on the inside of each tip of the fork connected to the camshaft compared to the fork of the handle. It has a thinner part.

(Example) To specifically explain this idea, Figures 1 and 2.
The example shown in the figure is a slider that has a lock function and a ratchet function, and the example shown in FIG. 3 has a lock function.

The example shown in FIG. 1 is shown exploded in FIG. 5, and is composed of a slider body 1, a puller 2, and a locking member 3. The locking member 3 is formed of a leaf spring, and has a Hanging legs 4
Following the horizontal part 5, a raised part 6 bent into a chevron shape, and an engaging part 7, and a stop claw 8 protruding from the horizontal part 5 and projecting downward is provided. The slider body 1 has an upper piece 9 and a lower piece 10 integrally formed with each other at a connecting part 11 at the tip, and the leg part 4 of the locking member 3 is fixed to the front surface of the connecting part 11 by crimping. The upper piece 9 has a window hole 13 through which the stop claw 8 is inserted, and a mounting portion 14 that fixes the engaging portion 7 so as to be movable up and down.

On the other hand, the handle 2 is an elongated plate whose tip end is formed into two forked parts 15,15.
A cam shaft 16 is installed between the tips of 5, and
The camshaft 16 has a rectangular or elliptical cross section, is offset downwardly between the two prongs 15, and projects slightly forward from the front end of the two prongs. In this handle 2, the two-pronged part 1 is attached to the inner side of each tip of the two-pronged part 15, 15 that is connected to the camshaft 16.
5 is provided with thin wall portions 17, 17 which are thinner than those in FIG. 5, and the one shown in FIG.
The upper surface of the camshaft 16 is formed lower in two stages to increase the strength of the protruding portion of the camshaft 16. In addition, the one shown in FIG.
7 and 17.

Next, in the example shown in FIG.
It is of the type that locks by protruding between the engagement teeth e, and in this case as well, the forked portions 15, 15 of the pull handle 2 are provided with thinner portions 17 as in the previous example.

This device has the above-mentioned structure, and when the handle 2 is tilted parallel to the upper piece 9 as shown in FIG. As shown in FIG.
The slider may stop while being in pressure contact with the slider, and at this time the raised portion 6 is in a floating state,
A large space is created between the raised part 6 and the upper piece 9, and when the slider body 1 slides by the ratchet function, the handle 2 swings laterally, and the handle 2 is twisted laterally as shown in FIG. The tip corner of one of the two forked parts 15 fits into the space of the raised raised part 6, but since the thin part 17 with a lower upper surface is formed at the corner of the two forked part 15, The downward biasing force of the king member acts effectively without blocking, and the stop claw 8 comes into contact with the flat surface e2 of the head of the engagement tooth, the slider stops, and the handle is twisted laterally, causing the forked part 1 to stop.
The inside part of the tip of 5 is the raised part 6 of the locking member.
Even if the slider body 1 is located below, the upper surface of its inner side is low, so the slider body 1 moves forward only slightly.
It immediately becomes a normal lock state. Further, in the case of the example shown in FIG. 3, the same effect as in the above example can be obtained.

(Effect of the invention) The slider with a stop device for a slide fastener according to this invention is a slider in which the cam shaft of the pull is inserted under the protrusion of the locking member provided on the upper part of the slider body. A thinner part is provided on the inner side of each tip of the part, which is thinner than the forked part, so that when the slider stops, the raised part of the locking member remains floating, and the handle is twisted. Even if the tip of the fork fits into the space below the protrusion, there is a space between the upper surface of the camshaft and the lower surface of the protrusion, and the downward biasing force of the locking member still acts, causing the stop pawl to As soon as it comes off the flat surface of the engaging head, the normal locking action can be obtained by the biasing force.
