Description

[Detailed description of the invention] 〔Technical field〕 This invention relates to a time switch.

□ Conventionally, there is a time switch in which a setter is provided on a disc-shaped dial that rotates at a constant period, and the setter turns the micro-swift on and off via a switch lever. This type of time switch rotates the dial in one direction when setting the time. □Set the dial to the current time, but... The disadvantage was that the setting element engaging part of the switch/edge lever had a fully sloped surface on both sides in the direction of dial rotation, which would prevent the setting element from being strongly caught and make it possible to turn the dial in the forward and reverse directions. However, if the front surface of Mukai: Emansho is an inclined surface, the sui-edge contact point will become continuous, causing problems such as burning at the contact point.

□ [Object of the invention]. (7) '7 Moe 4, Tsuiya 1vkiE reverse LC times 1. "t
The purpose of the present invention is to provide a time switch capable of setting a time T and also providing rapid disconnection of contacts.

□ [Disclosure of hh] The time switch of the present invention is provided with a setter on the diamond μ that rotates at a constant cycle, and the setter fully opens and closes the border contact through the switch/edge lever. This is because both sides of the setter engaging protrusion in the direction of dial rotation are sloped, and the transmission mechanism that transmits rotation from the drive source to the dial is provided with a play that allows some forward rotation of the dial. By making both surfaces sloped in this way, the time can be set by turning the dial to all city roads. Since we have provided some play in the rotation and rotation transmission mechanism, when the setting element passes the switch engagement protrusion of the switch and edge lever, the temporary fast rotation of the dial will be h', and the rotation and rotation will be Provides quick disconnection of contacts.

Both the connecting rods 61 are hinged together.

Operation rotor rotates 70 times Minute wheel 23 via each gear 20 to 22
and rotates the dial 2 by turning the dial 24. The setting element attached to the dial 2 is turned on and deaf, and when the set time comes, the setting element 12 passes through the ON lever 39 while pushing the slope 60b (FIG. 12(A)), and the ON lever 39 is turned off. By moving the contacts 43 and 44 in the OFF state, contact, =:i, 45 via the moving bottle 55.
, 46 are turned on. 9 to 11 show the related parts of the protrusion 51 of the gear 25 that is fitted with the on-lever 39 and the diamond v2. When the setter 12 is in contact with the slope 60b and the parallel portion 60c of the on-lever 39, a force opposite to the rotational direction is applied to the dial lv2 by the on-lever 39, so that the protrusion 511-j of the gear portion 25 dial 20 The arcuate hole 520 comes in the direction of rotation. Next, setter 1
2 moves to the side 60a of the slope of the on-lever, the dial 2 is subjected to a force in the rotational direction by the on-lever 39, so that the protrusion 51 moves to the side opposite to the rotational direction of the circular arc hole 52 of the dial 2. The dial 2 instantaneously rotates in the +E force direction. Therefore, the contacts 45 and 46 (Fig. 5) are quickly disconnected. That is, if the dial 2 and the gear 25 are fixed, the setter engaging protrusion of the on lever 39 6017) If the empty surface of the setter passage 1 is made into the slope 60a, the contacts 45 and 46 will break while the setter 12 passes through the slope 60b at the normal rotational speed of the dial 2, resulting in a continuous connection. However, since the dial #2 and the gear part 25 are separate parts and the rotation is transmitted through the play between the circular hole 52 and the protrusion 51, the dial 2 is allowed to freely rotate in the forward direction, and the slope As in the case of 60a f vertical plane, quick disconnection of contacts 45 and 46' can be obtained.

Next, we will explain the case of doing it manually. off par 4
Move 8 to 0F71111, and this! The lP moving pin 55 is separated from between the on lever 39 and the push pin 59,
The on lever 39 no longer pushes the push pin 59. Therefore, the φ points 43 and 44 are in the on state and the contacts 45 and 46 are in the off state. Conversely, manual v t<-f ON 1
When moved to 1111, the moving pin 55 moves to the on lever 3.

Since 60b is provided on both sides, both forward and reverse rotation are possible. Therefore, it is easy to set the time and is convenient to use.

In addition, due to the structure of Kufufuchi 27, forward rotation (clockwise)
It is light and has claws for reverse rotation.

In the embodiment described above, play was provided between the protrusion 51 of the 25° toothed portion of the dial 2 and the arcuate hole 52 of the dial 20, but if the forward rotation of the dial 2 is applied to any part of the transmission mechanism 8. You can also set up some play that is allowed.

[Effects of the Invention] The time switch of the present invention has the advantage that it is possible to set the time by turning the dial /I/ in the forward and reverse directions, while also allowing quick disconnection of the contacts.
