Bamboo chopstick gun and combination method thereof

The invention relates to a bamboo chopstick gun which is played by a general child, in particular, relates to a construction and a combination method of an innovative bamboo chopstick gun which has a closer feeling of real pistol operation and can be used for waste.

China has a long history. Since ancient times, it has spread a variety of children's play, such as feather scorpion, grass leaf flute, slingshot slingshot, bamboo raft, bamboo head, bamboo chopsticks and so on. These children's play are mostly made by using materials that are easy to obtain in daily life, low in cost, and even waste without cost, showing the wisdom and creativity of our ancestors.

The traditional bamboo chopsticks are made with bamboo chopsticks for daily meals. Its structure is shown in Fig. 10, wherein (a) is a perspective view of a southwest perspective of a traditional bamboo chopsticks gun, and (b) is a front view of a conventional bamboo chopsticks gun. It is attached to the rear end of a bamboo chopstick, and the two sides are connected in parallel (can be fixed by rubber bands or other means, because it is a conventional technique, not shown in the drawing), and two other bamboo chopsticks are taken out and taken out by The bamboo chopsticks are cut into three short bamboo poles of one-half length, and the upper end of the first short bamboo pole is inserted into the rear end space of the two parallel bamboo chopsticks, at an appropriate distance. The upper ends of the other two short bamboo poles are inserted into the rear end of the two parallel bamboo chopsticks at an appropriate distance, and the lower ends thereof are oppositely connected to form a triangular handle with the two parallel bamboo chopsticks. The upper end of the first short bamboo pole, which is inserted into the space of two parallel bamboo chopsticks at an appropriate distance in front of the grip, is fixed by a rubber band. This first short bamboo rod acts as a trigger.

During operation, the rubber band is placed against the front end of the first bamboo chopsticks, and then wrapped around the upper end of the first short bamboo pole. At this time, the human hand (left hand) must hold the lower end of the first short bamboo pole to allow the rubber The ribs are positioned and will not fly out too early. After the rubber band is placed, one hand (left hand) is held by the lower end of the first short bamboo pole, and the other hand (right hand) is grasped by the grip. In the posture of the left and right dual-handed guns, after aiming at the target, the left hand pulls the first short bamboo rod (trigger) backward, so that the rubber band placed on the upper end is tilted forward due to the upper end, and the clamping effect is lost and fast. The bomb flew out.

This traditional bamboo chopstick gun can be said to be a simple and easy to make fun toy, but the length is too long, the front section of the barrel is only a bamboo chopstick, the front end of the rubber band abuts the area is too small, and must be operated The lack of holding both hands. Also remind us that when using bamboo chopsticks, you must pay attention to safety. You can only aim at still-life targets, but not people or animals.

The invention is based on the spirit of traditional children's play using materials that are easily obtained in daily life, and is created by means of waste utilization. One of the objects of the present invention is to improve the lack of the long length of the conventional bamboo chopsticks gun; the second purpose is to improve the area of the rubber crest that the traditional bamboo chopsticks are abutted, and the rubber band is not easily abutted; In the improvement of the traditional bamboo chopsticks gun operation, the lack of two hands must be maintained.

In order to shorten the length of the bamboo chopsticks, the length of the barrel of the traditional bamboo chopsticks is about two lengths of the bamboo chopsticks, and the trigger and the grip are taken in series, and the barrel of the bamboo chopsticks of the present invention is used. Two bamboo chopsticks are arranged in a narrow V-shape, wherein the trigger is placed in the space at the rear end of the V-shaped opening, so the length of the barrel is only the length of a bamboo chopstick. Thereby the first object of the invention is achieved.

Since the bamboo chopsticks of the bamboo chopsticks of the present invention are two bamboo chopsticks juxtaposed, the area of the front rubber band abutting is increased by 2 times compared with the traditional bamboo chopsticks. In addition, the front end of the general bamboo chopsticks has a tapered radius, and more The tapered radius forms a gap formed by the front end of the bamboo chopsticks to stabilize the one end of the rubber band. Thereby the second object of the invention is achieved.

The trigger system of the invention is placed in the open space of the rear end of the V-shaped bamboo chopsticks, and the grip is formed by a rectangular trapezoid, which is different from the triangular shape of the traditional bamboo chopsticks, so that it can be held by one hand during operation. Hold the grip and pull the trigger to push the rubber band up and fly out. Thereby the third object of the invention is achieved.

In addition to achieving the above three objectives, the present invention also maintains the convenience of traditional children's play, and even utilizes the waste of daily life, and conforms to the concept of resource recycling and environmental protection.

The invention has a reasonable structure, easy material extraction or waste utilization, and also provides a combination method which is easy to implement step by step in production.

Based on the foregoing technical idea, the invention can produce a shortened length of the bamboo chopsticks, a stable abutment of the rubber bands, one-hand operation, environmental protection concepts, and functions and effects that are easy to combine.
