Definitions
- the present invention relates to a piezoelectric ignition device, and an object thereof is to provide a small piezoelectric device which is capable of ignition operations with high accuracy.
- the ignition device comprises a case, a piezoelectric element fixed on one side of said case by means of a fixing covering, a hammer and a first spring both arranged coaxially with said piezoelectric element, a hammer pressing plate, a support member, said hammer pressing plate and said support member being joined rotatably in an inverted- V shape at an end each thereof, and a pressure plate,
- said pressure plate having a free end in contact with the joint between said support member and said hammer pressing plate, said hammer having a protrusion which engages with and disengages from the other end of said hammer pressing plate as said pressure plate is depressed.
- FIG. 1 is a diagram showing a front view of an embodiment of the present invention
- FIG. 2 is an enlarged front view of the embodiment of FIG. 1 showing a partial section thereof previous to its operation;
- FIG. 3 shows an enlarged front view of the same embodiment in operation
- FIG. 4 shows a perspective view of the same embodiment from which the pressure plate is removed.
- the reference numeral 1 shows a pizoelectric element fixed on one side of a chamber 4 having a fixed covering 3 in a case 2.
- the numeral 5 shows a hammer contained in the same chamber 4 and maintained pressed in contact with the piezoelectric element 1 by means of a spring 6 disposed on the right hand side thereof.
- the hammer 5 is provided with an engaging protrusion 7 which projects through the aperture 8 of the fixed covering 3, the fixed covering 3 having a pair of sloped portions 9 adjacent to the aperture 8.
- the numeral 10 shows a plate for pressing the hammer 5 and provided with an engaging portion 11 for engagement with the protrusion 7 of the hammer 5.
- the numeral 12 shows a curved support for holding the plate 10, and an end of the curved support 12 is attached to the case 2, and end of the engaging portion 11 of the plate 10 being rotatably mounted on the other end of the curved support 12.
- the hammer pressing plate 10 When pressure is applied to that end of the engaging portion 11 which engages with the support 12, the engaging portion ll rotates to its horizontal position thereby pressing the engaging protrusion 7.
- the hammer pressing plate 10 is fitted with a spring 13 which has a greater restitution force than another spring attached to the plate 14 described later.
- the pressure plate 14 has a free end opposed to that end of the engaging portion 11 of the hammer pressing plate 10 which is held by the curve'support 12.
- the pressure plate 14 is adapted to return to its original position by means of the spring 15.
- the numeral 16 shows a lead wire.
- the numeral 17 shows a roller fitted in the joint between the engaging portion 11 of the hammer pressing plate 10 and the curved support 12.
- the pressing of the free end of the pressure plate 14 causes the engaging portion, that is, a free end of the engaging portion 11 of the hammer pressing plate 10 to flatten into its horizontal position, whereby the free end of the engaging portion 11 which does not engage with the support 12 is pressed into contact with the engaging protrusion 7.
- the curved support 12 of the hammer pressing plate 10 rotates around the lower end thereof for the smooth mechanical operation of the hammer pressing plate 10.
- the hammer pressing plate 10 which is opposed to the pressure plate 14 is arranged at a relatively small angle with the horizontal line, and therefore the apparatus can be made low in height.
- the circular motion of the support 12 of the hammer pressing plate 10 which occurs when pressure is applied to the apparatus permits smooth ignition.
- the engaging portion 11 since the free end of the pressure plate 14 is in contact with an end of the engaging portion 11 of the hammer pressing plate 10, the engaging portion 11 operates without fail when the free end of the pressure plate 14 is depressed, thereby assuring accurate ignition.
- a piezoelectric ignition apparatus comprising a case, a piezoelectric element fixed on one side of said case by means ofa fixing covering, a hammer and a first spring both arranged coaxially with said piezoelectric element, a hammer pressing plate, a support member, a hinged joint between said hammer pressing plate and said support member, said hammer pressing plate and said support member being rotatably joined at one end thereof in an inverted V-shape, and a pressure plate, said support member and said hammer pressing plate being rotatable about the joint therebetween, the other end of the support member being joined rotatably to said case by means of a hinge, said pressure plate having a free end in contact with the hinged joint between said support member and said hammer pressing plate and another end hinged to said casing, said hammer having a protrusion which engages with and disengages from other end of said hammer pressing plate as said pressure plate is depressed.
- a piezoelectric ignition apparatus according to claim 1, further comprising a second spring interposed between said pressure plate and said hammer pressing plate thereby assuring the engagement and disengagement of said protrusion of said hammer with and from said other end of said hammer pressing plate.
- a piezoelectric ignition apparatus according to claim 1, further comprising a second return spring interposed betwen said case and said support member, said return spring being adapted to return said support member and said hammer pressing plate to their original positions after the depression of said pressure plate.
