Abstract

<P>PROBLEM TO BE SOLVED: To provide an igniter for preventing an accident by ignition of fireworks from a separated place, safely playable without suffering a burn by a fire, and easily installable on the whole fireworks equipped with a fuse. <P>SOLUTION: The fuse is fixed to a nipping tool base body 5 having an ignition heater, a heating wire is ignited by contact, and a bend of the heating wire thereby is returned, to thereby solve the problem of causing a danger such as a burn when handling the fire, for quickly separating from the fireworks such as mainly a rocket and a cracker after igniting the fuse in conventional firework ignition. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention is a conductor igniter for preventing burns and accidents by igniting from a safe place by using a heating wire such as a nichrome wire as a conductor for launch fireworks or firecrackers.

  Some conventional electric ignition devices are equipped with an electrode rod, a heating wire, etc., in preparation for explosives and ignite by flowing electricity.

  However, the fireworks used were limited.

  With conventional fireworks ignition, fireworks such as fireworks and firecrackers must be separated quickly after igniting the lead, and there is a risk of burns when handling fire types.

  The present invention provides an ignition device that can prevent accidents by igniting fireworks from a remote place, can be safely played without being burned by fire, and can be easily attached to all fireworks equipped with a lead wire. It is an object.

  In order to achieve the above object, in the present invention, a heating wire such as a nichrome wire is installed at the tip of the clamping base, and the lead wire is fixed at the clamping portion, and the side of the heating wire is contact-ignited in the present invention. is there.

  In addition, a partition projection that matches the width of the heating wire is attached.

  In addition, a heating wire return tool is provided at the lower portion of the heating wire to prevent the heating wire from bending and causing poor ignition when the above-mentioned conducting wire is fixed with a pinch base and brought into contact with the heating wire several times.

  Accident is prevented by switch ignition from a remote place consisting of lead wire 4, and it can be played safely.

  Moreover, by attaching the protrusions 10, 11, 12, and 13, it is easy to attach the lead wire even in the dark.

  Further, the plate spring 8 and the heating wire receiving portion 17 can eliminate an ignition error due to poor contact.

  A fire conductor or other conducting wire is fixed to the ignition device, installed in a safe place, and burns and accidents are prevented by simple operations such as switch ignition from a remote place.

  The embodiment will be described with reference to the drawings. In FIGS. 1 to 4, the clip base 16 is provided with protrusions 10, 11, 12, and 13 for facilitating the mounting of the clip 5 and the conductor 7. An ignition heater 2 provided with a heating wire 1 is attached to a clamp base 16 provided with a lead wire 4 connected to a switch, a terminal part 3, and a spring 9, and held by a terminal part 15 and fixed with a screw 14, A leaf spring 8 provided with a heating wire receiving portion 17 is attached to the rotating portion of the base body 16 and ignited by a switch connected to the lead wire 4 with a conducting wire 7 such as fireworks to be used in between.

  In the embodiment shown in FIG. 5, the heating wire 1 pushed by the conducting wire 7 is used as shown in FIG. 6 by the leaf spring 8 having the heating wire receiving portion 17 attached to the rotating portion of the ignition device base 16. Each time the leaf spring 8 is moved, and the heating wire 1 is pushed back by the heating wire receiving portion 17, it is possible to prevent an ignition error regardless of how many times it is used.

  It is sectional drawing of an ignition device.   It is a perspective view which shows the state formed by mounting | wearing an ignition device with a leaf | plate spring and a heat generating wire receiving part.   It is a perspective view which shows the Example of an ignition device.   It is a figure which shows the internal structure which shows the example of a conducting wire attachment.   It is a waist | lumbar part side view of the ignition device by an Example.   It is a waist | lumbar part side view of the ignition device by an Example.
