Abstract

PURPOSE:To reduce the number of part items by providing a return spring for energizing an operation handle in opening direction and a display spring for energizing a leakage indicating member in display position. CONSTITUTION:When a non-equilibrium current is carried to cable way, this is detected by a zero-phase current transformer 129 to generate a secondary output, which is the amplified by an amplifier 135 to turn on a switching element 136, and the movable iron core 171 of an electromagnet device 149 is attracted on a fixed iron core 170 side by excitation of coil to push up the locking 165 of a transmission lever 147 by the locked part 181 of the iron core 171. The engaging part 160 of the transmission lever 146 is pushed down by the engaging part 157 of the lever 147 to rotate a top ring 50 through the protruding piece 78 of the top ring 50 inserted to the opening part 159 of the lever 146, and the movable contact of an interrupting mechanism 24 is tripped from a fixed contact 92 to open a contact 60. The locked part 153 of a leakage indicating member 144 is released by the rotation of the lever 147, and a display part 150 is protruded from the operation hole 15 of a housing 1 by a spring 145 mounted on an operation handle 52.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a time scale, hours, minutes,
The present invention relates to a multi-range timer specification switching device that switches time units such as seconds.

[0002]

2. Description of the Related Art A conventional multi-range timer specification switching device is constructed as shown in FIGS.
On a front surface of a disc-shaped character plate 1, a pointer 2 which is rotated by a timer operation is arranged, and a scale 3 is provided around the character plate 1 and a numerical display window 4 is provided at an appropriate interval in the circumferential direction. And a time unit display window 8 is formed between the start end and the end of the number display window 4 of the character plate 1. An annular numeral plate 5 is arranged on the back surface of the character plate 1, and a numeral 6 displayed from the numeral display window 4 is printed on the numeral plate 5. This number 6
Is (0, 0.2, 0.4, 0.6, 0.8, 1.0),
(0,1,2,3,4,5), (0,2,4,6,8,
10) and (0, 10, 20, 30, 40, 50) are set as a set, and by appropriately rotating the number plate 5 eccentrically, the numbers of a proper set and the number display window 4 can be matched. ing. A notch 7'is provided in a portion of the numeral plate 5 on which the numeral 6 is not printed. This cutout 7 '
A disk-shaped time unit display plate 9 is arranged on the back side of the number plate 5 in a portion corresponding to, and the time unit display plate 9 is printed with time units 10 such as seconds, minutes and hours. The time unit 10 is displayed from the time unit display window 8 through the notch 7 ', and by rotating the time unit display plate 9, the time unit 10 is displayed.
The display of is switched.

[0003]

However, in such a conventional example, the time unit plate 9 is arranged on the back side of the numeral plate 5, and the time unit 10 is provided with the time unit display window 8 through the notch 7 '. Since it is displayed from, the viewing angle θ becomes narrow, and there is a problem that visibility is poor. The present invention has been made in view of the above problems, and an object of the present invention is to provide a specification switching device for a multi-range timer that can widen a viewing angle and improve visibility.

[0004]

In order to achieve the above object, a specification switching device for a multi-range timer according to the present invention has a pointer 2 arranged on the front surface of a character plate 1 for rotating by a timer operation, and is arranged around the character plate 1. Is provided with scales 3 and numerical display windows 4 are formed at appropriate intervals in the circumferential direction, hour unit display windows 8 are formed at appropriate positions on the character plate 1, and a number plate 5 is arranged on the back surface of the character plate 1. The numeral 6 displayed on the numeral plate 5 is printed on the numeral plate 5, and in the specification switching device of the multi-range timer in which the time unit display plate 9 is arranged on the outer circumference of the numeral plate 5, the 0 numeral portion of the numeral plate 5 is displayed. The wide notch 7 is provided in the part where the number 6 is not provided extending from this part to the vicinity of the end of the number 6 by eliminating the time unit in the notch 7 part. By placing shows plate 9 was the number plate 5 and time unit display plate 9 substantially flush to, characterized in that formed by printed characters plate 1 to 0 digit 11.

[0005]

According to the above structure, the number plate 5 is provided with the wide cutout 7 by eliminating the number 0 so that the time unit display plate 9 and the time unit display plate 9 are flush with each other. The time unit display plate 9 can be arranged, and the time unit display plate 9 can be brought close to the time unit display window 8 to increase the viewing angle θ of the time unit 10 to improve visibility. Even if the number plate 5 does not have a 0 number, it can be displayed by the common 0 number 11 of the character plate 1.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The internal mechanism of the timer according to the present invention is actually fair.
The description is omitted because it is the same as that disclosed in Japanese Patent No. 30985. As shown in FIGS. 1 and 2, a pointer 2 which is rotated by a timer operation is arranged on the front surface of a disk-shaped character plate 1, and a scale 3 is provided around the character plate 1 and is suitable in the circumferential direction. The numeral display windows 4 are formed at regular intervals, and the time unit display window 8 is formed between the start end and the end of the numeral display window 4 of the character plate 1. In the case of the present invention, the numeral display window at the starting end of the conventional example is eliminated and 0 numeral 11 is printed. An annular numeral plate 5 is arranged on the back surface of the character plate 1, and a numeral 6 displayed from the numeral display window 4 is printed on the numeral plate 5.
This number 6 is (0.2, 0.4, 0.6, 0.8, 1.
0), (1,2,3,4,5), (2,4,6,8,1)
0), (10, 20, 30, 40, 50) as a set, and by appropriately rotating the number plate 5 eccentrically, the numbers of an appropriate set and the number display window 4 are matched. . A notch 7 is provided in a portion of the numeral plate 5 where the numeral 6 is not printed. In the case of the present invention, the portion where the numeral 6 of 0 is conventionally printed is eliminated and widely cut out, and is cut out to the inner circumference. This cutout 7
The time unit display plate 9 is arranged so as to be substantially flush with the number plate 5 at the portion where is positioned, and the time unit display plate 9 is printed with the time unit 10 such as seconds, minutes, hours and the like. . The time unit 10 is displayed from the time unit display window 8, and the display of the time unit 10 is switched by rotating the time unit display plate 9. At this time, since the time unit 10 is displayed directly from the time unit display window 8, the viewing angle θ becomes wide as shown in FIG. 1 and the visibility is improved.

[0007]

As described above, according to the present invention, the number plate is set to 0.
By eliminating the number and providing a wide notch, the time unit display plate can be arranged so that the number plate and the time unit display plate are flush with each other, and the time unit display plate is brought close to the time unit display window. Therefore, it is possible to improve the visibility by enlarging the viewing angle in units of time, and to display with a common 0 number on the character plate even if there is no 0 number on the number plate.
