摘要 | A firearm chambering sound emulation mechanism, comprising a receiver (1, 1a, 1b) and a hand grip (11, 11a, 11b) movably mounted thereon and having a function of reciprocal movement. Via a coupling member the hand grip (11, 11a, 11b) is coupled to a striker (14,14a, 14b) that is received in the receiver (1, 1a, 1b). A knocker (15, 15a, 15b) in the receiver (1, 1a, 1b) is arranged adjacent the path of reciprocal movement of the striker (14, 14a, 14b). The striker (14,14a, 14b) and knocker (15, 15a, 15b) have corresponding wavy surfaces (141, 151). As the hand grip (11, 11a, 11b) is pulled rearward to emulate a chambering operation or as it moves forward, the striker (14, 14a, 14b) moves simultaneously along the knocker (15, 15a, 15b) against which it is urged by a biasing element (16), thereby generating loud and clear sounds similar to the chambering sound of an actual firearm. This invention helps improve a player's sense of reality. | ||||||

说明书全文 | The present invention generally relates to firearm bolts, and more particularly to a firearm bolt emulation mechanism that generates a highly emulating chambering sound to effectively enhance the pleasure of a player. In the 16th century, artillery was reduced in size and matchlocks were invented as the beginning of the light firearms. Since then, firearms gradually become extremely offensive weapons with the combination of innovation of mechanical engineering and novel types of gunpowder. The development of industrial techniques also helped advance the progress of firearms, making them widely used in military and police applications, hunting, and sports. Firearms are restrained and controlled in many countries and firearm fancies are only allowed to purchase toy gun or model guns for collection and possession. A variety of emulation firearm bolts that does not possess antipersonnel force are available in the market and some are referred to as toy gun bolts or BB guns. The toy gun bolts that are currently available in the market have made a great progress in respect of the materials and the manufacturing techniques thereof, making the outside appearance of the toy gun bolt highly closely emulating an actual firearm. However, the internal structure of the toy gun bolt is generally not made emulating an actual bolt. For example, the operation of the toy gun bolt does not provide a power vibration and chambering sound that an actual gun may generate, making the operation of the toy gun bolt very monotonous and boring. Toy gun bolts that generate recoil forces are also available in the market. Although a recoil force is generated in pretty much the same way as an actual firearm, the sound generated when chambering is made is still poor. Electronic sound generation has also been available for such a purposes, but there is a significant difference from the chambering sound of an actual firearm. The primary object of the present invention is that through connection made with a gas tube, when a hand grip is pulled and moved, the gas tube drives a striker to move so as to realize a structure for emulation of an actual bolt in a limited space. Another object of the present invention is that striking and contacting between a striker and a knocker may generate sounding that is very close to actual chambering sounds so as to achieve an advantage of high degree of emulation thereby enhancing the pleasure of a user in the use of the device. To achieve the above objects, the present invention structurally comprises a bolt body, a gas tube received in the bolt body and coupled a the hand grip, a striker received in the bolt body and coupled to an end of the gas tube, a knocker received in the bolt body and set on a moving path of the striker, and an abutting member fixedly mounted to one side of the striker to enhance tight engagement thereof with the knocker. The gas tube comprises an elastic element fit thereon for reciprocal movement of the hand grip. Further, the striker has one side forming a wavy section and the knocker has a side corresponding to the wavy section and forming a contact section. As such, for percussion, the hand grip is first pulled rearward for chambering and at the same time, the hand grip drives the gas tube to have the gas tube drive the striker. Further, the hand grip is returnable by means of a force applied by the elastic element in an opposite direction. During the process of position returning, the striker powerfully strikes the knocker, making the wavy section and the contact section rub each other so that they generate loud and clear sounding in an intermittent manner, achieving the sound of chambering of an actual firearm and thus improving the pleasure of a player. The technique described above can overcome the problems of the conventional toy gun bolt that generates no chambering sound as an actual firearm and is thus monotonous and boring and lacks of the true sense of reality, thereby achieving a practical improvement of the present invention. The foregoing objectives and summary provide only a brief introduction to the present invention.
