Description

Powered Flashlight {hand operated electric flash lamp}

The present invention relates to a power generation flashlight, and more particularly, to a power generation flashlight that is operated by hand without a battery.

In general, flashlights are a useful tool used to illuminate dark places indoors or outdoors, connecting batteries to light bulbs to make them glow. However, flashlights are often useless where batteries are exhausted or where new batteries cannot be purchased.

In addition, the batteries are discharged naturally during long-term storage, so care should be taken in storing them. Especially in the case of emergency flashlights, the batteries may be discharged during use in an emergency. have.

In addition, after the battery is discharged there is a problem causing environmental pollution due to the waste battery.

The present invention was devised to solve the above problems, and it is not necessary to inspect or replace a battery that is consumed due to the discharge of the battery. It is also an object of the present invention to provide a flashlight that can be used to suit the purpose of use by adjusting the perspective of the light.

In order to achieve the above object, the power generation flashlight according to the present invention includes a drive handle having a rack gear for linear movement on one side and moving about a hinge point; A flywheel that rotates in one direction in association with a rack gear that linearly moves when the driving knob moves; A generator including a rotor connected to the flywheel to generate current by driving the rotor; And a light bulb connected to the generator by an electric circuit.

Here, the power generation flashlight further includes a relay gear installed between the rack gear and the fly wheel, converting the linear motion of the rack gear into a rotational motion and transmitting the rotation gear to the fly wheel.

The relay gear is a small gear connected to the rack gear to drive the linear motion in a circular motion to increase the rotational speed, and is coupled coaxially with the small gear to convert a small circular motion into a large circular motion Including large gear to let

According to the present invention, the fly wheel includes a drive tooth that is engaged with the large gear and rotates; Inner teeth coaxially formed on the flywheel; And a clutch pedal that engages with the inner tooth when the flywheel rotates in one direction and applies a rotational force to the flywheel, and separates from the inner tooth when the flywheel rotates in a reverse direction and does not apply a rotational force.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 show the configuration of a power generation flashlight according to a preferred embodiment of the present invention. Referring to these drawings, the power generation flashlight of the present invention is composed of a drive mechanism 10, a generator 50 and a bulb 60.

The drive mechanism 10, the generator 50 and the bulb 60 may be combined into a single plastic body, the appearance of which is not different from other flashlights except for the drive handle 20.

Referring to FIG. 3, which shows a detailed configuration of the drive mechanism 10, the drive mechanism 10 includes a drive handle 20 and a flywheel 40 that rotates in association with the drive handle 20, and It is composed of a relay gear for transmitting the driving force of the drive handle 20 to the flywheel (40).

One end of the driving handle 20 is rotatably coupled to the flashlight body 100 by a hinge point 21. The rack gear 20a is attached to the other end of the drive handle 20.

The relay gear is composed of a small gear 12 that meshes with the rack gear 20a and rotates, and a large gear 14 that is coaxially coupled with the small gear 12.

The flywheel 40 is engaged with the large gear 14 and rotates with the driving gear 16, the clutch pedal 30 attached to the driving gear 16, and the clutch pedal 30 is intermittently rotated to provide rotational force. The inner tooth 32 is applied.

The generator 50 is composed of an electromagnet 42 and a rotor connected to the shaft of the flywheel 40. In addition, the flashlight of the present invention includes a reflector 64 for focusing the light emitted from the bulb 60 in one direction and a perspective control switch 62 for adjusting the focus.

Hereinafter, the operation of the present invention having the configuration as described above will be described in detail.

First, the user moves the drive handle 20 downward while holding the flashlight. Then, the rack gear 20a connected to the drive handle 20 is linearly moved downward, and the small gear 12 and the large gear 14 of the relay gear meshed with the rack gear 20a rotate in the direction of the arrow. Done.

Subsequently, as the drive gear 16 engaged with the large gear 14 rotates, the clutch pedal 30 coupled to the drive gear 16 makes a circular motion.

At this time, when the drive gear 16 rotates in the direction of the arrow in the drawing, the clutch pedal 30 is caught by the inner tooth 32 and the locking jaw 32a, and thus the inner tooth 32 and the flywheel 40. This rotates in one direction. Accordingly, power is generated in the generator 50 while the rotor connected to the shaft of the flywheel 40 rotates, and light is emitted from the bulb 60 electrically connected thereto.

Next, when the drive knob 20 is released, the drive knob 20 is moved upward by the elastic force of the spring 21a, and the rack gear 20a is linearly moved upward while the small gear 12 and the large gear 14 are moved. ), The drive gear 16 is rotated in the reverse direction.

Then, the clutch pedal 30 coupled with the drive gear 16 slips over the slip step 32b of the inner tooth 23 and thus cannot apply rotational force to the flywheel 40, and thus the flywheel ( 40) continues to rotate in the original direction of rotation. This can be understood as the same operation as the ratchet on the rear wheel of a bicycle.

As described above, the bulb 60 may be brightened by continuously rotating the flywheel 40 in one direction through the vertical movement of the driving knob 20.

In addition, when adjusting the perspective or focus according to the point to be illuminated, this can be achieved by moving the perspective control switch 62 back and forth to change the position of the bulb. In other words, the perspective control switch 62 is designed to be useful for near-field use when the light is pushed forward to the near point, and is designed to be useful for long-distance use when the back is pulled backward.

The power generation flashlight according to the present invention can be used continuously without a battery, and its configuration is simple and easy to operate, and anyone can use it. The operation of the handle 20 and the replacement of the bulb 60 can be used permanently. And by using the drive handle 20 can be seen a separate exercise effect to raise the grip force, and also because the drive handle 20 is not necessary to switch on and off, because the battery does not use environmental pollution due to waste batteries There is no need for a separate charger and there is an advantage of resource protection.
