Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a time switch, for example, a time switch that determines whether to execute or cancel a preset opening/closing program with a 24-hour cycle on each day of the week from Sunday to Saturday. The present invention relates to an improvement in a time switch that can be automatically selected and set, and can also be set by an occasional interrupt manual operation that allows both the program and execution or cancellation settings for each day of the week to be performed independently and with priority.

[Prior Art] A conventional time switch of this type is shown in FIG.
In FIG. 5, (1) is a 24-hour scale plate, which is driven by a synchronous motor or the like (not shown) and rotates once every 24 hours.

(2) is a setter, which is attached to the outer peripheral portion of the 24-hour scale plate (1) at a position corresponding to a desired time by suitable means such as screw tightening. 24 as time passes
When the time scale plate (1) rotates, a mechanism such as an opening/closing lever, which will be described later, and a setter (2) are engaged and separated, and the switch (3) is opened and closed at a desired time. (4) is a one-week scale plate, which is driven in the same manner as the 24-hour scale plate described above and rotates once per week. Also, this one week scale plate (4) is a 24 hour scale plate (
1) It maintains a constant positional relationship with the time position.

(5) is a rotary switch that rotates the one-week scale plate (4), and through a suitable mechanism such as a series of cam wheels (not shown), each step for each day of the week from Sunday to Saturday is divided into 24 steps. Switches sequentially one step at a time,
Progress through 7 steps in one week.

(6) is a single-pole three-stage selection switch with a 24-hour scale plate (
1) This is for selecting whether to execute or cancel the 24-hour cycle program set in J2 for each desired day of the week, and there are 7 in total corresponding to each day of the week from Sunday to Saturday. are provided. Each selection switch (6) can be set to three states. That is, the first state is 1TAUTOj, and its terminal is connected in series with the switch (3). The second state is 0FFj and its terminal is open. The third state is FONj and its terminal is connected in parallel with the switch (3).

Note that the common terminal of the selection switch (6) is connected in series to the contact point of the rotary switch (5) corresponding to the day of the week.

Next, its operation will be explained. Here, FIG. 1 shows a case where the contact point of the rotary switch (5) is located on Tuesday (in other words, it indicates that the current day is Tuesday), and the Tuesday selection switch (6) is set to FAUTO. It shows.

In this state, the rotary switch (5) and the selection switch (6) are already electrically connected, so
The load (7) is directly controlled by the opening/closing operation of the switch (3). That is, opening and closing are controlled according to a program set by adding a setter (2) to the 24-hour scale plate (1). If the switch (3) is closed in this state (that is, the load (7) is on), if necessary, you can manually turn off the load (7) by temporary interrupt operation. Switch the selection switch (6) to the 1'OF Fj state. In addition, when the switch (3) is open (that is, the load (7) is in the OFF state), if you want to make the load (7) a human by a temporary interrupt operation, press the manual selection switch (8). lI'o Nj
Switch to state. Needless to say, the operation described in L takes Tuesday as an example, but the same operation can be performed on other days of the week depending on the position of the time switch (5).

As described above, in the time switch of this structure, the selection switch (6) corresponding to each day of the week can be arranged in three types
FAUTO Yu, ff0N1. and FOFFj), it is possible to decide whether to execute or cancel a 24-hour cycle program for each desired day of the week. In addition, control that is prioritized and independent of the contents of the program by temporary manual manual operation can also be freely performed by operating the selection switch (6) on a predetermined day of the week. Therefore, it is easy to control equipment that does not operate during holidays [1], and the purpose can be achieved without stopping the entire time switch, for example, for maintenance and inspection of loads (7) (such as radios), which is very convenient. be.

However, the conventional example shown in FIG. 5 has the following drawbacks. In other words, ■ As mentioned above, the opening/closing elements include the switch (3) and the low-return switch (5).
) and a selection switch (6), and in particular, as many as seven selection switches are required for each day of the week. As a result, the number of parts increases during manufacturing, and the assembly and adjustment operations become complicated, leading to an increase in costs.

■Also, the opening/closing capacity of the rotary switch (5) that can be stored in the internal space of a time switch with a general capacity is limited by its external dimensions. Normally, it is significantly lower than the switching capacity of the switch (6). Therefore, the opening/closing capacity of the entire time switch is determined to be the lowest opening/closing capacity of the rotary switch (5), and as a result, the opening/closing capacity of the time switch becomes low.

Even if you perform a temporary interrupt operation by manually operating the selection switch (6) for each day of the week corresponding to 1 second and increase or decrease the load independently from the predetermined program, the day will change as time passes (1 week The scale plate (4) advances by 24 hours (for example, from Tuesday to Wednesday), and the low-return switch (
5) also steps to the next day of the week. In that case, the load (7
) is determined by the state of the selection switch (6) for the next day of the week [j, so in advance, set the selection switch (6) for the next day of the week together with the selection switch (6) for the corresponding day of the week. Otherwise, there is a problem that the desired interrupt operation cannot necessarily be executed continuously.

[Summary of the Invention] This invention was made to solve the above-mentioned conventional drawbacks, and it is possible to select in advance whether to automatically execute or cancel an opening/closing program of a fixed cycle at another fixed cycle that is longer than the opening/closing program. - It has a function that can be set and a function that can temporarily interrupt the state different from the setting, and even when the day changes, the interrupt operation performed before the day change can be performed after the day change without taking any special measures. In addition to ensuring reliable operation, only one opening/closing element is required, which previously required many.
To provide a time switch opening/closing device in which assembly table adjustment is simple and inexpensive, and the opening/closing capacity does not decrease.

[Embodiment of the Invention] An embodiment of the invention will be described below with reference to FIGS. 1 to 4.

In Figure 1, (11) is a 24-hour scale plate, (12)
are one-week scale plates, which rotate around shafts (13) and (14) fixed to supports (not shown), respectively. (15
) and (16) are setters, and each corresponds to the 24-hour scale plate (1
1) and the one-week scale plate (12), and rotates together with these respective scale plates (11) and (12).

(17) and (18) are opening/closing levers, one end of which is provided opposite each scale plate (11), (12), and is linked with setters (15), (16). , fixed shaft (18
). The fixed shaft (18) also rotatably supports the intermediate levers (20) and (21).

Here, the opening/closing levers (17), (18) and the intermediate levers (20), (21) are both supported by the fixed shaft (19), but their supporting portions are slidable. , each can be rotated separately and independently.

(22), (23) springs (interlocking means) to open/close levers (17), (18), respectively, with projections (17a) at one end.
, (18a) and the projections (20a), (2Ia) at one end of the intermediate levers (20), (21). Further, the opening/closing levers (17), (18) and the intermediate levers (20), (21) have stoppers (17b), (18b), (20b), (2
1b), the opening/closing lever (17)
, (18) and the intermediate 1/par (20), (21) cannot rotate relative to each other in the direction of the tensile force of the springs (22), (23), and maintain a constant angle.

(26) is an auxiliary lever rotatably attached to the fixed shaft (27). The upper surface of this auxiliary lever (26) is connected to the other end of the intermediate levers (20), (21) and the adjustment screw (
28) and (28). Further, the lower surface of the auxiliary lever (26) is equipped with a switch (3) having a normally open contact.
It faces the plunger (31a) of 1). here,
This plunger (31a) is moved upward, that is, in the direction in which the switch (31) is in the open state, by a suitable means such as a spring (not shown) inside the switch (31).
22) and (23).

Intermediate levers (20), (2) via auxiliary lever (26)
1) Pushing up the other end. Also, please adjust the above 2.
8) and (28) are for finely adjusting the operation reversal position of the switch (31).

In this way, the opening/closing levers (17) and (18) are connected to the setter (1).
5) and (16) and rotate in the direction of arrow A, the intermediate lever (
20) and (21) rotate, and the other end is attached to the auxiliary lever (2
6) Press. This auxiliary lever (26) is activated by pressing the plunger (31a) of the switch (31) by pressing either or both of the intermediate levers (20) and (21).
).

Now, (33) is a manual lever, and the convex parts (33a), (33b)', (33c) provided on its outer periphery are
, (33d) are for manually interrupting the switch by pressing the other ends of the opening/closing levers (17), (18) and intermediate levers (20), (21).

This operation will be explained based on FIGS. 2 to 4. However, in order to simplify the explanation, FIGS. 2 to 4 only illustrate the opening/closing mechanism of the switch (31) interlocked with the one-week scale plate (12).

Figure 2 shows how to manually move the manual lever (33) in the direction of arrow B.
It shows a state in which it has been rotated to the position 'oFFj. At this time, the convex portion (33b) rotates in the direction of arrow B from the position indicated by the dashed line to the position indicated by the solid line, and separates the other end of the eight (21) from the plunger (31a). Therefore, even if the opening/closing lever (18) is pushed up by the setter (16) and rotates in the direction of arrow A from the dashed-dotted line to the position shown by the solid line, the spring (23) only stretches and remains in the middle./<-(21) does not rotate, the plunger (31a) of the switch (31) is not pressed.

This means that while the time switch is operating according to a predetermined program, the switch (31) must be manually turned in the direction of arrow B to open the switch (31) as a temporary interrupt manual operation. If it moves, it means that the switch (31) can be opened regardless of the contents of the program.

FIG. 3 shows a state in which the manual lever (33) has been manually rotated in the direction of arrow C (to the joNj position. At this time, the convex portion (33d) does not touch the other end of the opening/closing lever (18). Press to rotate this opening/closing lever (18) in the direction of arrow A. As a result, the intermediate /<-
(21) also rotates, and the other end presses the plunger (31a) of the switch (31) via the auxiliary lever (26). Therefore, the plunger (31a) of the switch (31)
is always pressed regardless of whether the setter (16) and the opening/closing lever (18) are engaged or disengaged.

This means that while the time switch is operating according to a predetermined program, the switch (
31) by rotating the manual lever (33) in the direction of arrow C, it means that the switch (31) can be closed regardless of the contents of the program.

Figure 4 shows the manual lever (33) in the fAUTOj position, with its convex portions (33b) and (33d)
is not involved in any way in the rotation of the opening/closing lever (18) and the intermediate lever (21). Therefore, in this state, the switch (31) automatically opens and closes according to the program set by the setter (18) by the operation of each part in conjunction with the above-mentioned one-week scale plate (12).

Here, in FIGS. 2 to 4, in order to simplify the explanation, only the manual interrupt operation for the program of the one-week scale plate (12) has been explained, but at the same time, the operation shown in FIG. Convex portions (33a), (33c)
Therefore, the same interrupt operation as that for the weekly scale plate (12) is performed for the program of the 24-hour scale plate (11).

In the above configuration, the manual lever (33), the opening/closing lever (
17), (18) and intermediate levers (20), (21)
By using these in combination, only one switch (
31), it is possible to select and set in advance the execution or cancellation of a program for each desired day of the week, and execute it, as well as to perform temporary interrupt operations with priority independent of the program.

Further, since no switching element such as a rotary switch is used, the switching capacity of the time switch is determined only by the switch (31), and the switching capacity does not decrease as in the conventional example. Furthermore, as shown in FIGS. 2 and 3, when the manual lever (33) is rotated and set to the ff0Nj or [1OFFj state, the switch (31) is set to the setter (15), (16) Since it opens and closes independently from the setting contents, the daily operation (which was a drawback of the conventional example)
In the present invention, there is no change in the content of the interrupt operation due to the rotation of the opening/closing lever (17) for one week, and the content of the interrupt is reliably maintained without any special operation.

In this embodiment, a 24-hour scale plate is used as the first scale plate, and a 1-week scale plate is used as the second scale plate. The same effect can be achieved as well. Moreover, it goes without saying that the same effect can be achieved even if the scale plate is composed of three or more scale plates.

[Effects of the Invention] As explained above, according to the present invention, there is a function that allows you to select and set in advance whether to automatically execute or cancel an opening/closing program with a fixed cycle at another fixed cycle that is longer than the opening/closing program. This device has a function of temporarily interrupting a state different from the setting, and reliably executes the interrupting operation performed before the daily change even after the daily change without taking any special measures. Furthermore, since only one opening/closing element is required, whereas conventionally a large number of opening/closing elements are required, assembly and adjustment are easy and inexpensive. Furthermore, there is no reduction in switching capacity.
