Description

[Detailed Description of the Invention] This invention relates to a full-length winding structure that improves the shape of the full-length stopper.

Conventionally, in devices such as time switches that use all the weights as a driving source, a method was used in the past in which all the weights in a winding set were attached to the clock mechanism and then loaded into the case.

Therefore, all the weights must be attached at the time of assembling the mechanism, which has the disadvantage of being complicated and cumbersome in terms of work procedure, and poor work efficiency. A method of attaching weights has been started and put into practical use.

However, the whole weight 2 is attached between the two-port case 11 and the clock mechanism 5 in Fig. 1A, and the outer end 21 of the whole weight is bent into a U shape, and the hook of the case is fixed to the part 14. In the roll-up structure, the case has a large opening at the hook portion 14, and this opening must be separately covered with a lid or the like, which has the disadvantage that the shape of the lid covering the opening becomes complicated.

Furthermore, the lid is fixed with screws or the like, which has the disadvantage of poor workability.

Also, as shown in Figure 1C, there is a full weight insertion opening 1 on the outside of the case 11.
There is a full winding structure in which the entire ribbon is inserted through the insertion opening, rolled up, and the outer end of the ribbon is fixed with a full stop fitting 35.

This full stopper fitting 35 is formed by bending a metal plate into an L-shape.

One side of this metal fitting is inserted into the insertion port 15 along the entire weight 2, and the other side has a notch b that is the same as the overall weight width a dimension, and a small size where the neck of the outer end of the entire weight is locked. A notch C is formed.

When all the weights are inserted and locked, all the weights are inserted into the insertion port and rolled up, and the full weight stopper 35 is pressed against the case wall surface 16 of the insertion port, preventing the weight from floating up. The weight gets caught up.

If the winding work is done while pressing the full stopper 35 with your finger, you may cut your finger with the full spindle, or the stopper may come off during the work, and the outer end of the full stop may not be locked by the stopper. It has the disadvantage of getting caught inside the case.

In view of the above-mentioned drawbacks, the object of the present invention is to propose a full-winding structure in which all the weights can be wound in without holding down the full-weight stopper during full winding.

The feature of this invention is that the full stop that covers the opening on one side of the case body is provided with an opening that has an anti-separation part and an abutting part that comes into contact with the full weight. The purpose is to prevent them from leaving.

The present invention will be explained below with reference to illustrated embodiments.

In FIGS. 2, 3, and 4, a storage chamber 12 for all the weights 2 is formed in a case body 11 of a device 1 such as a time switch whose driving source is all the weights.

An opening 13 is bored in the outer periphery of the storage chamber 12.

As shown in FIG. 3C, the opening 13 is provided with a flange 13a, which is a movement prevention part that prevents the movement of the full hook 3 described below, in a direction perpendicular to the surface of the case body 11, and a groove 13b113C is formed. .

Further, a step portion 13d is provided on the upper surface of the opening portion 13.

In the opening 13, a full hook 3 is fitted into the grooves 13b and 13C so as to abut the stepped portion 13d and cover the opening.

The full hook 3 is formed of a metal plate in an L-shape, and one side 3a is fitted into the grooves 13b and 13c, and the other side 3b rides on the step 13d.

An opening 31 is bored in one side 3a of the full hook 3.

As shown in FIG. 5, the shape of the opening 31 is an opening 31a with a width of 4 which is slightly larger than the width of the entire weight 2, and a width e of the neck 21a formed at the outer end 21 of the entire weight 2. a small notch 31b having approximately the same dimensions as the opening 31a and the notch 3;
It is formed by a surface 31C that connects 1b.

The side of the opening 31a on the case body 11 side is connected to the detachment prevention part 3.
2, and there is a total weight of 2 between the preventing portion 32 and the surface 31C.
A contact portion 33 is formed with which one wide side of the contact portion 33 contacts.

When the entire weight 2 is wound into the device 1 using the above-mentioned full weight as a driving source, the full hook 3 is fitted and held in the grooves 13b and 13c of the opening 13.

Next, the starting end of the full weight 2 is inserted into the opening 31 a having the width dimension d of the opening 31 of the full hook 3 , and the starting end is inserted toward the center of the storage chamber 12 .

A knob shaft 4 is disposed in the center of the storage chamber 12, and a starting end thereof is hooked onto a pin of the knob shaft (not shown).

Next, when the knob shaft 4 is rotated, all the weights 2 are sent into the storage chamber 12 and wound.

At this time, the entire weight 2 is inserted into the notch 31 within the opening 31 of the entire hook 3.
Since the spring force acts in the b direction, that is, in the direction in which all the weights 2 try to unravel, the wide side surface of all the weights 2 in the direction in which the spring force acts comes into contact with the abutting portion 33, and the whole hook is loosened. Place the stop 3 on the flange 13
A force acts to press against a.

In addition, since the detachment prevention part 32 is interposed between the case body 11 and the side surface of the middle of the full weight 2, the full hook 3 is secured to the groove 1.
3b and 13C, the full hook 3 will not come off from the case body 11.

The work of winding up all the weights 2 is progressing, and the notch 31 of all the hooks is closed.
When the neck portion 21a at the outer end is positioned at point b, the neck portion 21a is moved to the notch 31b by the spring force in the direction of the notch 31b of the full weight 2.
It falls and becomes locked.

The full hook 3 can be rolled up without being held by fingers or the like.

FIG. 6 shows another shape of the opening 31 of the full hook 3.
This is an example in which a part of the case body side of a is cut out leaving the detachment prevention part 32.

Remaining portion 3 of opening 31a left by notch groove 31d
The length 1e, that is, the length of the detachment prevention part 32, is longer than the dimensional length at which the entire weight 2 wobbles when it is rolled up.

By providing the notch groove 31d in this way, the full hook 3 can be attached to the case body 11 after the starting end of the full weight 2 is hooked onto the pin of the knob shaft 4, or during the middle of winding up the full weight 2, and the above-mentioned The trouble of having to insert the starting end of all the weights 2 into the fully hooked opening and then inserting them into the storage chamber 12 is eliminated, and work efficiency is improved.

When attaching the entire hook 3 to the case body 11 in the middle of winding it up, it must be attached so that the entire weight 2 definitely comes into contact with the contact portion 33.

In the case of this example as well, it may be attached to the case body before being rolled up, similar to the above-mentioned full hook fixing.

Figure 7 shows all the hooks 3 in the same direction as the winding direction of all the weights 2.
This is an embodiment of a full hook type in which one side is inserted into the opening of the case body, and in this case, the opening 31 of the full hook 3 may be formed into a blind hole as in FIG. 5 above, Notch groove 31
d may be provided on the case body side, or the opening 31 may be formed by a notch groove 31d provided on the side opposite to the case body side.

The above-mentioned full-winding structure may be used in a device other than a time switch that uses a full weight as a driving source.

Since the present invention is configured as described above, the movement of the full hook is regulated by the full weight and does not come off from the case body when the full hook is reeled in, so there is no need to fix the full hook with your fingers or the like. This means that only a small amount of force is required.

As a result, the risk of being cut by the full weight is extremely reduced.

Furthermore, a fully folded structure can be obtained which has excellent effects such as preventing operational defects in which the outer end of the full weight is not caught by the full hook and is rolled into the storage chamber.
