JPS60213879A - Hand with light emitting diode and conduction pin for timepiece illumination - Google Patents

Abstract

PURPOSE:To make the time easy to look at even at a dark place by attaching an illuminator to the hand of a large timepiece. CONSTITUTION:LEDs 8-10 are provided at tips of a second hand 5, a long hand 6 and a short hand 7 while conduction pins 12-14 with a vertically operable super-mini wheel spring on the back thereof. LEDs 23 are provided at key points at numeral parts on a dial plate. The LEDs 8-10 emit light while pointers are running with the conduction pins 12-14 fixed on the back thereof contacting a positive electrode plate 20.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for making it easier to read the time even in dark areas by attaching a lighting device to the hands of large watches, since it is inconvenient to read the clock at night or in a dark room. Until now, there have been watches that used luminous paint, but as time passes, the light source disappears and becomes invisible, which is inconvenient. The present invention is an illuminated hand that can be easily seen even in a dark area by attaching an illuminating device to the hands of a watch.The present invention will be explained with reference to the drawings as follows.

5, the second hand 6, the long hand 7, and the hour hand.
9.10. 12, 13, 14 electrically connected pins with ultra-compact vertically operating small wheel springs are provided on the back side of the light emitting diode. This power supply pin does not add any resistance to the hands that move with slight force, and also accurately contacts the upward and downward movement of the hands, as well as the bending of the dial plate, etc., and supplies positive current to the light emitting diode.Wiring of the power supply pin 18 The negative current shown in the figure is made by passing current through the hour wheel of the cylindrical pinion 15 in the middle center 16 of 17, which attaches the second hand, long hand, and short hand, and passing a negative current from each wheel to the light emitting diode using the lead wire 19 or the same method. 23 light emitting diodes are provided at important points in the number part of the dial.

2.3.4 on the circumference of the dial. Make a groove of 20 mm on the bottom of the groove.
Added to alarm clocks, table clocks, etc. in which the electrical pins fixed to the back of each pointer touch the positive electrode plate and the lights are illuminated by light-emitting diodes at the tips of the second, long, and hour hands while moving the hands. It can have functions. 4. Light-emitting diode pointers with electrical pins for watch lighting that can be used for battery watches and electric watches with a completely simplified structure and a cheap pointer lighting method.4. Brief explanation of the drawings Figure 1 shows the grooves 2.3.4 on the dial plate 1 and the 5 seconds hand 6 long hand 7.
8.9.10 on the hour hand and its tip. A light emitting diode of 23. is also provided in the math section of the dial. A plan view showing the installation of the light emitting diodes of 12, 13, 14. The wiring diagram of 18 shows the state in which the current-carrying pin is in contact with the 20 positive electrode plates fixed to the dial plate, and the negative current is flowing through the center of the cylinder pinion 17 of the hour wheel 16 of 15. It is a sectional view of the needle, attachment, and dial plate on a vehicle.

Claims (1)

[Scope of Claims] Pointers having light-emitting diodes for lighting at the tips of the second hand, long hand, and short hand, and electric pins with upper and lower operating wheel springs fixed on the back side. Fix the light emitting diode to the number part of the dial. A positive current is applied to the dial below the circular orbit of the hands. A negative current is applied to the car, etc. where the pointers are attached. In addition, a negative current is applied to the light emitting diode using the same method using a lead wire or a metal needle from the needle attachment part. The energizing pin of each pointer moves the hands while supplying contact current to the positive electrode plate, and lights up the light emitting diode. Pointers with a light emitting diode and an electrical pin are used to supply current to the needle body, with negative current coming from the vehicle to which the needle is attached and positive current coming from the dial. The structure, device, and method configured as described above are provided.
