Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a heddle frame hanging fitting for connecting a heddle frame to an opening device such as a dobby machine.

[Conventional technology]

The structure of a conventional general hanging fitting will be described with reference to FIG.

Reference numeral 1 denotes an upper heald bar of a heddle frame, and several (usually a pair of left and right) suspension fittings are attached to the upper portion of the heald bar 1.

This hanging metal fitting is composed of a metal fitting body 2 and a link fixing lever 3
And a torsion coil spring 4, and the lower end connecting portion 5a of the suspension link 5 attached to the lower end of the heddle frame suspension member (not shown) such as a wire is connected to the suspension fitting.

The metal fitting body 2 has a mounting seat 2 for the heald bar 1 at the lower end.
a and 2a, and a boss portion 2b at substantially the center, respectively, and the coupling portion 5a of the suspension link 5 is fitted to the boss portion 2b.

One end of the link fixing lever 3 is pivotally attached to the lower portion of the metal fitting body 2 by a pivot 6, and as shown by the solid line in FIG. 5, overlaps with the front surface of the connecting portion 5a of the suspension link 5 fitted to the boss portion. The link is rotated between a link fixing position for holding the connecting portion 5a in a fitted state and a link releasing position of the phantom line in FIG.

The spring 4 is wound around the pivot 6 of the link fixing lever 4, and the spring 4 urges the link fixing lever 3 toward the link fixing position. Then, while the link fixing lever 3 is pushed down to the link releasing position against the spring 4, the connecting portion 5a of the suspension link 5 is connected to the boss portion 2b of the metal fitting body 2.
Mating or disengaging with respect to.

[Problems to be solved by the device]

However, such a conventional hanging metal fitting has the following drawbacks.

(A) The link fixing lever 3 is merely pushed toward the link fixing position by the spring force, and is not fixed at the same position.

Further, in order to make full use of the spring force, a relatively large clearance is required at the lever pivotally attached portion by the pivot 6 so that the rotation resistance does not act on the lever 3.

For this reason, the link fixing lever 3 rattles up, down, left and right during operation of the loom, and the lever pivotally attached portions (the metal fitting body 2, the pivot 6 and the lever 3) are severely worn and the life of the metal fitting is shortened.

(B) Since there is no means for holding the link fixing lever 3 in the link releasing position, when the link 5 is attached to or detached from the metal fitting body 2, the link fixing lever 3 pushed down to the link releasing position for each fitting is directly held with one hand. I had to keep it in this open link position. For this reason, this link attachment / detachment work, that is, the work of connecting / separating the heald frame to the shedding device becomes troublesome, and this problem is particularly problematic in the case of a loom incorporating ten or more heald frames, such as a loom for a handle. It was getting serious.

Therefore, the present invention can eliminate such conventional defects, prevent rattling of the link fixing lever to improve the life of the metal fitting, and can automatically hold the link fixing lever at the link releasing position. The present invention provides a hanging fitting for a heddle frame.

[Means for solving the problem]

The present invention comprises a metal fitting body attached to a heddle frame and a link fixing lever attached to the metal fitting body, wherein the metal fitting body has a boss portion to which a suspension link is fitted, and the link fixing lever is the boss. It is pivotally attached to the metal fitting body so that it can be rotated between a link fixing position that overlaps the front surface of the suspension link that is fitted to the part and holds the link in the fitted state, and a link release position that deviates from the front surface of the link. And
The metal fitting body is provided with a ball and a spring for pressing the ball toward the link fixing lever side at a portion where the link fixing lever faces both the link fixing and releasing positions, and the link fixing lever is provided with A ball fitting portion that fits into the ball at the link fixing position is provided.

[Action]

With this configuration, the ball is elastically fitted to the ball fitting portion with the link fixing lever set to the link fixing position, and the fitting action holds the link fixing lever at the link fixing position.

That is, instead of simply pushing the link fixing lever toward the link fixing position by the spring force as in the conventional case,
Since the ball is held at the link fixing position by the fitting action of the ball and the ball fitting portion, (I) at this link fixing position, the movement of the link fixing lever can be suppressed and the lever can be reliably fixed. Therefore, the rattling of the link fixing lever can be prevented during the operation of the loom, and the wear of the lever pivotal portion can be suppressed.

(II) No force acts on the link fixing lever toward the link fixing position, and the lever is provided with a holding force at the elastic contact portion with the ball even at the link releasing position, so that the lever is moved to the link releasing position. Automatically retained. Therefore, the work of attaching and detaching the link to the metal fitting body can be efficiently performed.

〔Example〕

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

 Reference numeral 11 is a metal fitting body, and 12 is a link fixing lever.

The metal fitting body 11 is basically the same as the conventional metal fitting body 2 shown in FIG.
a and 11a, and a boss portion 11b into which the coupling portion 5a of the suspension link 5 is fitted is provided at substantially the center.

The link fixing lever 12 has a lower end portion pivotally attached to the lower end portion of the main body 11 by a pivot 13 on one of the left and right sides of the metal fitting body 11, and the connecting portion 5a of the suspension link 5 fitted to the boss portion 11b.
Between the link fixing position that overlaps the front surface of the same and holds the joint portion 5a in the fitted state, and the link release position that deviates from the front surface of the joint portion 5a as shown in phantom lines in FIG. 2 and FIG. Move. Reference numeral 12a is a knob portion for rotating the link fixing lever 12.

The metal fitting body 11 is provided with a recessed hole 14 in a front surface portion thereof on the side where the link fixing lever 12 is provided, at a portion where the lever 12 faces at both the link fixing and link releasing positions.

A coil spring 15 is provided in the recessed hole 14, and the ball 16
However, the coil spring 15 is provided in a state in which a spring force in a direction of pressing the link fixing lever 12 is applied.

On the other hand, the link fixing lever 12 is provided with a ball fitting hole 17 having a diameter slightly smaller than the ball diameter at a position corresponding to the ball 16 at the link fixing position.

Therefore, when the link fixing lever 12 is set to the link fixing position as shown in FIGS. 1 to 3, the ball 16 fits into the ball fitting hole 71, and this fitting action causes the link fixing lever 12 to move. The link is held at a fixed position.

As described above, since the elastic fitting force between the ball 16 and the ball fitting hole 17 is used as the lever holding force, the link fixing lever 3 is simply moved to the link fixing position side by the spring force like the conventional metal fitting shown in FIG. The movement of the link fixing lever 12 toward the link release position is surely suppressed as compared with the case of only pushing.

Further, the vertical movement of the lever 12 is also blocked by the fitting force.

Further, the link fixing lever 12 need only be rotatable between the link fixing and link releasing positions, and it is not necessary to positively provide a clearance at the lever pivotally connecting portion as in the conventional case. It becomes possible to obtain a large frictional resistance (rotational resistance).

Because of these points, the link fixing lever 12
It is possible to prevent any rattling of the lever, and to suppress the abrasion of the lever pivotal connection part.

On the other hand, when the link fixing lever 12 is rotated toward the link releasing position, the ball 16 separates from the ball fitting hole 17 and presses against the inner surface of the lever as shown in FIG. At this time, the link fixing lever 12 is not acted on by any force, such as the spring force of the conventional metal fittings, to move it toward the link fixing position. Therefore, the pressure contact force of the ball 16 causes the lever 12
Are automatically held in the link release position.

Therefore, unlike the conventional metal fittings, it is not necessary to hold the link fixing lever 3 in the link release position by hand when attaching / detaching the suspension link 5 to / from the metal fitting main body 2.
The attachment / detachment work of the link 5 with respect to 11, that is, the connection / separation work of the heald frame to the opening device becomes extremely easy.

In order to prevent the link fixing lever 12 from being rotated beyond the link release position, a step portion 11c is provided near the lever pivot portion of the metal fitting body 11, and the link fixing lever 1
2 contacts the stepped portion 11c at the link release position.

By the way, in the above embodiment, the case where the link fixing levers 12 are provided only on one side of the metal fitting body 11 has been described, but the link fixing levers 12 may be provided symmetrically on both the left and right sides of the metal fitting body 11.

Alternatively, similarly to the conventional metal fitting shown in FIG. 5, one link fixing lever 12 may be provided obliquely from one lower part on the left and right sides of the metal fitting body 11 to the upper part on the other side.

Further, as the ball fitting portion of the link fixing lever 12, instead of the ball fitting hole 17 of the above-described embodiment, a concave hole is formed in the lever 12 (a part of the lever 12 is bulged outward to form a dent inside). May be provided).

[Effect of device]

As described above, according to the present invention, instead of pushing the link fixing lever toward the link fixing position by the spring force as in the conventional case, the ball provided in the elastically supported state on the metal fitting body and the link fixing lever are provided. Since it is held at the link fixing position by the fitting action of the ball fitting portion, the link fixing lever can be reliably fixed at the link fixing position.

Therefore, it is possible to prevent any rattling of the link fixing lever and suppress the abrasion of the lever pivotally attached portion during the operation of the loom, so that the life of the metal fitting can be remarkably improved.

On the other hand, no force acts on the link fixing lever to move it to the link fixing position, and even when the lever is given a holding force at the pressure contact part with the ball even at the link releasing position, the lever automatically moves to the link releasing position. Held in.
Therefore, the work of attaching and detaching the suspension link to the metal fitting body, that is, the work of connecting and separating the heald frame to the opening device can be performed very easily and efficiently.
