[Industrial applications]

 The present invention relates to a cigarette power expansion / contraction light which is a light to be used by being inserted into a cigarette power supply of an automobile, and which has a light portion extending and retractable from the power supply portion.

[0002]

[Prior art]

 Various devices are operated by using a cigarette power supply provided in a car. Among such devices is a light designed to illuminate the hand in the car.

In this conventional light, the neck portion of the light is bent flexibly when it is attached to the cigarette power source, and therefore, it can be used in the front seat, but when used in the rear seat, It had the drawback of short lead wires.

However, in the above-described light, if a long lead wire is used so that it can be used in the backseat as well, when it is used in the front seat, the lead wire has an extra length, which is an obstacle. There is.

[0005]

[Problems to be solved by the device]

 The present invention is a light to be used by being inserted into a cigarette power supply of an automobile, and an object thereof is to provide a cigarette power expansion / contraction light in which a light part is extendable from the power supply part.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the cigarette power expansion / contraction light of the present invention has a hollow case 2 fixed to the rear end of a socket 1 which is detachably inserted into a power hole 10 of a cigarette power supply. The mainspring 3 is housed in the mainspring 3, and the end of the mainspring 3 on the center side is fixed to the hollow case 2, while the flat cable 4 is connected to the tip of the mainspring 3 by connecting a long flat cable 4. The flat cable 4 can be freely wound around the outer circumference of the mainspring 3, and the flat cable 4 is pulled out from a space 2a opened in the outer circumference of the hollow case 2 to fix a light case 6 for connecting a small light bulb 5 to the end of the flat cable 4. The light case 6 and the flat cable 4 are electrically connected to each other, and the other end of the flat cable 4 is connected to the plus terminal 1a and the minus terminal 1b of the insertion base 1. Characterized in that connected to.

[0007]

[Action]

 In the above structure, when the insertion base 1 is inserted into the power supply hole 10 of the cigarette power supply, the telescopic light of the present invention is electrically connected to the cigarette power supply.

The flat cable 4 remains wound in the hollow case 2 in a normal natural state, and when the light case 6 is pulled out, the flat cable 4 is pulled out against the winding force of the mainspring 3.

The flat cable 4 is flexible and can be freely bent to be used within the extended range of the flat cable 4 regardless of the irradiation position of the light. When the pulled-out state of the pulled-out light is released, the flat cable 4 is wound around the outer circumference of the mainspring 3 in the hollow case 2 due to the restoring force of the mainspring 3, and the light is stored near the void 2a of the hollow case 2.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 (a) is an overall view showing the internal state of the cigarette power expansion / contraction light of the present invention, and FIG. 1 (b) is the cigarette power expansion / contraction light of FIG. 1 (a) inserted into the power hole of the cigarette power supply. It is a figure which shows the state which carried out, and FIG.1 (c) is the state which pulled out the flat cable. FIG. 2 is a plan view showing a state where the mainspring and the flat cable are connected, and the mainspring is in an extended state. FIG. 3 is a schematic view showing the winding state of the mainspring of FIG. 1 (b).

In FIG. 1B, the cigarette power supply has a positive terminal 10 a provided at the innermost portion of the power supply hole 10, and the side surface of the power supply hole 10 constitutes a negative (ground) terminal 10 b.

In FIG. 1 (a), the telescopic light according to the present invention has a socket 1 that can be removably inserted into the power hole 10 of the cigarette power source, and the innermost part of the socket 1 is formed. Has a plus terminal 1a attached thereto, and the side portion of the insertion cap 1 acts as a minus terminal 1b. When this insertion base 1 is inserted to the deepest part of the power supply hole 10, the insertion base 1 and the power supply hole 10 connect the positive terminal and the negative terminal of each other.

Normally, the power supply hole 10 of the cigarette power supply is provided with an engagement / disengagement mechanism for preventing the inserted insertion cap 1 from being detached due to vibration or the like. This mechanism is provided in the present invention. You may do it.

A hollow case 2 is fixed to the rear end of the insertion base 1. As shown in each of FIG. 1 and FIG. 3, the hollow case 2 has a shallow cylindrical shape and accommodates a mainspring 3 therein, and the center end of the mainspring 3 has a locking shaft 3a. The central end of the mainspring 3 is fixed to the hollow case 2 by fixing and fixing the locking shaft 3a to the side portion of the hollow case 2.

Further, as shown in FIG. 2, a long flat cable 4 is superposed on the tip of the mainspring 3 and is joined by a rivet 8 or an adhesive to wind the flat cable 4 around the mainspring 3. Then, the flat cable 4 is pulled out from the void 2a opened in the outer periphery of the hollow case 2. However, the mainspring 3 shown in FIG. 2 is in the extended state, and in the natural state, the center end portion of the mainspring 3 having the locking shaft 3a fixed thereto is wound in the center.

A light case 6 is fixedly attached to the tip of the drawn flat cable 4, and a small light bulb 5 is attached to the light case 6.

The positive and negative lead wires 4 a and 4 b of the flat cable 4 and the light case 6 are electrically connected to each other so that the small light bulb 5 can be connected. The other end of the flat cable 4 is connected to the mainspring 3 Is connected to the insulation-coated lead wires 7a and 7b fixed along with the lead wire 7a and 7b at the same time when the mainspring 3 is wound, and the other ends of the lead wires 7a and 7b are connected to the insertion cap 1. Connect to the plus terminal 1a and the minus terminal 1b.

In the present invention, a ratchet mechanism may be provided on the side of the mainspring in the hollow case 2 so that the flat cable 4 can be freely stopped in the middle of being pulled out.

In the above structure, when the insertion base 1 is inserted into the power supply hole 10, the insertion base 1 is electrically connected to the cigarette power supply, and when the light case 6 is pulled out, the flat cable 4 is connected to the mainspring 3. The irradiation position of the light can be freely changed within the extended range of the flat cable 4 by being pulled out against the entrainment force and bending freely.

When the light is pulled out, the flat cable 4 is wound around the mainspring 3 in the hollow case 2 by the restoring force of the mainspring 3, and the light case 6 is stored in the hollow case 2 near the void 2 a. To be done.

[Effect of device]

 As described above, the cigarette power expansion / contraction light of the present invention can be easily used in a vehicle while it is plugged into the cigarette power supply of an automobile, and the light can be freely extended from the power supply to provide the front seat only. Instead, it can be used in the back seat, and when it is not needed, the flat cable can be wound in a hollow case, or it can be taken out from the power supply hole in this wound state.

Since the flat cable of this telescopic light can be extended flexibly, it can be used with an appropriate length without creating extra length, and when using it in the front seat, the extra length is an obstacle. It never becomes.
