Mechanisms for moving hands of a clock showing the time of sunrise and sunset

摘要

6.0.0. Abstract.; Definition of sunrise and sunset using hours is optional, and in some cases, and the necessary information to the determination of the status of the light of day and night. For this purpose, there are various methods for determining the state of the day and night. One method of determining the time of sunrise and sunset at that point location and the current time, an apparatus in hours of mechanical, electromechanical with a daily 24 hour dial additional mechanism for moving the two hands of a clock showing the time of sunrise and sunset at areas with certain geographical coordinates, and time zone. Arrow mounted on the central axis of the movement, perform a reciprocating movement on the daily dial. The principle for explaining operation of arrows a moving mechanism for determining the time of sunrise and sunset, shown in Figures "Annex 1" and "Appendix 2" to the essay. The proposed utility model allows to determine the time of sunrise and sunset on the daily 24-hour clock face of mechanical and electromechanical hours. Moving arrows occurs based on the slide motion along a closed groove, deposited on the impeller mechanism that performs rotational movement. The shape of the groove is designed for astronomical algorithms of the Earth and the Sun's motion. Movement of the slide is converted into a reciprocating movement of additional arrows indicate time of sunrise and sunset using guide bar groove and connecting rods. The mechanism for moving the hands of a clock showing the time of sunrise and sunset has a number of manual settings for a reset operation state, and changing the settings for other geographical coordinates of the area where the user is located.; The proposed mechanism is installed in a clock with a daily 24 hour dial, the user can promote the rational allocation of the time of day, has cognitive value to determine the phenomena associated with the change of time of day or night. Members of hours with a mechanism for moving the clock hands show the time of sunrise and sunset to help navigate in the state of the time of day or night when working in confined spaces from daylight.; Explanation of the operation device and the proposed utility model, "The mechanism for moving the hands of a clock showing the time of sunrise and sunset" shown in "Appendix 1" Fig.1 and "Appendix 2" Fig.2 to the essay.
