Description

  The present invention relates to a rocket fireworks launcher, and more particularly, to a fireworks launcher for repelling birds and beasts using a firework whose firework body flies like a rocket as called rocket fireworks or flying fireworks.

  In recent years, animals such as crows and monkeys have become harmful birds and beasts, and have started to cause damage to crops and injuries to residents, and in airfields, birds are sucked into aircraft engines and cause accidents. Has also started to occur.

  Therefore, in farmland, residential areas, airfields, etc., rocket fireworks whose fireworks fly like rockets are used, and contrivances have been made to ward off birds and monkeys with their sound and sudden fireworks fire.

  And since the rocket fireworks are fired while scattering the sparks, the following are used from the viewpoint of ensuring safety.

  That is, as shown in FIG. 6, the cylindrical body 3 is vertically established from the center of the plate-shaped or dish-shaped substrate 1 to form the fireworks launching stand 5, and the branch portion 9 of the rocket fireworks 7 is connected to the cylindrical body 3. This is an example in which the fireworks launch table 5 is used for retreating birds and beasts by inserting from the tip and igniting the fire conductor 13 extending from the firework body 11 of the rocket fireworks 7.

  However, the above-described fireworks launch table 5 or launch platform body 15 as a rocket fireworks launcher is used by placing them on the ground in the same manner as the fireworks launch as a natural play. Since it fires vertically toward the, it cannot fire in any direction.

  Therefore, it is difficult to fire the rocket fireworks 7 toward birds and monkeys that have appeared in farmland, residential areas, airfields, etc., and it is not powerful to surprise and drive away birds and monkeys. The reality is that it is difficult to expect.

  The present invention has been made under such circumstances, and it is easy to surprise birds and monkeys as pests with strong force, and can be expected to have a high wiping effect of pests, and the structure is simple and safe. The purpose is to provide a high rocket fireworks launcher.

  In order to solve such a problem, the cultivation support tool according to the present invention has a cylindrical body whose tip side is open, and a fire-resistant rocket fireworks launch rod in which a branch of rocket fireworks is inserted and supported in this cylindrical body. And a fireproof protective plate which is fixedly attached to the firing rod at a position where the firing rod is penetrated and close to the tip side, and the peripheral edge portion is close to the cylindrical body side. It is characterized by letting the animal go away by launching rocket fireworks from the stick.

  The protection plate according to the present invention can be formed in a funnel shape that wraps the above-described cylinder.

  The protective plate in the present invention is preferably formed by molding from a metal plate.

  The firing rod according to the present invention can have a plurality of cylindrical bodies dispersedly.

  The rocket fireworks launcher according to the present invention uses a rod-shaped body having a cylindrical body whose front end is opened, and forms a fire-resistant rocket fireworks firing rod in which a branch of the rocket fireworks is inserted and supported in the cylindrical body, The fire rod is penetrated through the fireproof protective plate, and the protective plate is formed so as to approach the cylinder side at a position close to the tip side of the fire rod, and the rocket from the fire rod is fixed firmly to the fire rod. Since it is characterized by letting the animal go down by firing fireworks, if you hold the other tip side of the firing rod, you can fire rocket fireworks in any direction, such as birds and monkeys as harmful birds and beasts Can be astonished with a strong force, and it can be expected to have a high wiping effect on harmful birds and beasts. In addition, a protective plate prevents sparks from rocket fireworks and ensures high safety.

  In addition, in the configuration in which the protective plate is formed in a funnel shape that wraps the cylinder side of the firing rod described above, it is difficult for the sparks scattered from the rocket fireworks that have been ignited to reach the user side more securely, ensuring safety in use. Is even more certain.

  Further, in the configuration in which the protective plate is formed from a metal plate, the protective plate is not easily damaged by the sparks scattered from the ignited rocket fireworks.

  And in the structure which disperse | distributes and forms a several cylinder on the said firing stick, it becomes possible to shoot a plurality of rocket fireworks in a short time.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Parts common to the conventional example are denoted by the same reference numerals.

  1 and 2 are a perspective view and a cross-sectional view showing a rocket fireworks launcher for repelling birds and beasts according to the present invention.

  1 and 2, the rocket fireworks launcher 21 of the present invention is configured to have a rocket fireworks launch rod 23 and a fireproof protective plate 25 fixed thereto.

  The firing rod 23 is a fire-resistant, for example, metal rod-shaped body having an arbitrary length of about 15 m from a long and narrow 15 cm having a cylindrical body 27 having at least one tip P side opened.

  As will be described later, the branch portion 9 of the rocket fireworks 7 is inserted into and supported by the distal end side cylinder 27 of the firing rod 23.

  As shown by the broken line in FIG. 1, the inside of the firing rod 23 may be integrally or separately closed except for the tubular body 27 of the firing rod 23, as shown by the broken line in FIG. The stopper plug 23 a may be closed so as to be inserted into the firing rod 23 from the other tip portion p, and at least the tip only needs to be the cylindrical body 27.

  The protective plate 25 is formed in a funnel shape from a metal plate, and a boss portion 31 is formed on the outside (in the direction opposite to the expanding direction) so as to form a through hole 29 at the protruding central tip. ).

  The protective plate 25 is inserted into the through hole 29 so as to expand toward the tip P side of the firing rod 23, and the boss 31 is attached to the outside of the firing rod 23 with adhesive, welding, soldering or other known fixing. It is firmly fixed by the method.

  The protection plate 25 is fixed toward the tip P side of the firing rod 23 so that the tip P of the firing rod 23 does not protrude from the open end surface (periphery) of the protection plate 25, that is, from the open end surface of the protection plate 25. It is fixed so that it is located inside. The firing rod 23 can be fixed in a positional relationship in which the tip P side protrudes from the open end surface of the protection plate 25.

  On the outer periphery of the other end p of the firing rod 23 that protrudes from the boss portion 31, there is a cylindrical cover 33 that is elastic, and a gripping portion that can be grasped by the user's hand is formed.

  Therefore, the rocket fireworks launcher 21 of the present invention can point the tip P side of the firing rod 23, that is, the open end of the protection plate 25 in an arbitrary direction, if the user holds the cover 33 by hand. is there.

  As shown in FIG. 3, the rocket fireworks launcher 21 according to the present invention has a long and thin firework body 11 of about 5 to 6 cm, and a branch that is fixed to the bamboo firewood and the like along the long side and is extended downward. A conventionally known rocket fireworks 7 having a portion 9 is prepared, and the branch portion 9 is inserted and supported from the tip P of the firing rod 23 into the cylinder 27 to ignite the lead 13 extending from the bottom of the rocket fireworks 7 and fire. If the tip P side of the rod 23 (the open end of the protective plate 25) is pointed in an arbitrary direction, the rocket fireworks 7 fly in the indicated direction.

  Accordingly, when crows and monkeys appear in farmland, residential areas, airfields, etc., the rocket fireworks 7 can be easily fired in those directions, and the crow fireworks 7 and the fireworks body 11 suddenly fly. You can surely drive away and monkeys.

  Moreover, since sparks and sparks scattered from the lower part of the firework main body 11 due to ignition of the rocket fireworks 7 hit the protective plate 25, if the protective plate 25 is selected to have an appropriate diameter, for example, at least 5 cm or more, the hand holding the cover 33 No sparks or sparks are hit, and it is safe for the user. Even if the firework body 11 bursts, the user is unlikely to be damaged.

  In particular, the protection plate 25 is formed in a funnel shape, is opened toward the tip P side of the firing rod 23, and is formed so as to wrap around the cylindrical body 27 side. Therefore, safety is particularly high.

  Furthermore, since the launch rod 23 and the protection plate 25 are made of a metal material, they are less likely to be damaged by the sparks scattered from the ignited rocket fireworks 7 and have the advantage of good durability.

  However, the firing rod 23 and the protective plate 25 in the present invention are not limited to metal, and may be, for example, a synthetic resin. However, a material having good fire resistance and heat resistance is preferable.

  Although the protective plate 25 in the rocket fireworks launcher 21 of the present invention described above is formed in a funnel shape so as to wrap the tip P of the launch rod 23, the present invention is not limited to this.

  For example, as shown in FIG. 4, if a protection plate 35 formed in a disk shape and bent so that the peripheral edge rises toward the tip P side of the firing rod 23 is used, the rocket fireworks 7 scatter. The spark never reaches the hand that hits the protective plate 35 and holds the cover 33, and is similarly safe.

  The protection plate 25 in the rocket fireworks launcher 21 according to the present invention can achieve the object of the present invention as long as the peripheral portion is formed so as to approach the cylindrical body 27 of the firing rod 23.

  Furthermore, in the rocket fireworks launcher 21 of the present invention, as shown in FIG. 5, a configuration in which a plurality of cylindrical bodies 37 are formed in a distributed manner on the tip P side of the firing rod 23 is possible. If 37 is distributedly formed, a plurality of rocket fireworks 7 can be fired in a short time.

  By the way, in the above-mentioned firing rod 23, the depth dimension S (see FIG. 3) from the tip P is slightly shorter than the gap 13 between the squib 13 and the tip of the branch 9 of the rocket fireworks 7 (see FIG. 1). If selected, the conducting wire 13 of the rocket fireworks 7 in which the branch portion 9 is inserted from the tip P of the firing rod 23 is not hidden in the cylindrical body 27 of the firing rod 23, so that the conducting wire 13 is easily ignited.

  In addition, if the insertion length of the stopper plug 23a inserted from the other end p side of the firing rod 23 is made variable and the depth dimension S from the tip P of the firing rod 23 is formed to be variable, various branch portions 9 can be formed. It can also handle rocket fireworks 7 having a length.

  In addition, as a form of formation in the plurality of cylinders 37 to be dispersedly formed, a configuration in which a slight angle is provided with respect to the longitudinal (axial direction) direction of the firing rod 23 as shown in FIG. It is optional to use a configuration in which it is placed in parallel with the firing rod 23 in the same direction.

  However, even in that case, the protective plates 25 and 33 need to be formed so as to open to the tip side of all the cylinders 27 and 37.
