Abstract

PURPOSE: A Khansan-re-pound-bow is provided for smooth manipulation for the shooting an arrow with the bow. CONSTITUTION: A Khansan-re-pound-bow comprises a handle(1), a recurve bow rim(2), a compound bow rim(3), a cam pulley(4), a bowstring(7), and a cam returning string(8). The recurve bow rim, the compound bow rim, the cam pulley are hung in the cam returning string. In case the bow is manipulated, tension is applied to the compound bow rim and the recurve bow rim. In case an arrow is shoot, the elasticity of the recurve bow rim is applied to the arrow. And the arrow is shot through the reinforcing force of the compound bow rim.

The recurve bow-type bows show a force distribution as shown in Figure 1, which maximizes the resilience when pulled into full length (a typical elastic graph of a recurve bow), and the cam-dorle (cam wheel) used in compound bows. Is to make the best bow in the world with its features and performance.

Hansan Palace, Recurve Bow, Compound Bow

Conventional recurve bow is a working principle that puts tension on the rim which is an elastic body, pulls the demonstration, and blows the arrow with the force that the elastic body restores, and the compound bow is attached to the elastic of the rim by attaching a cam puller (cam wheel) It works by changing the resilience to speed and blowing arrows.

The recurve bow is very weak when you pull the bow for the first time, but it is extremely powerful when you are working on it, and you have to hold the right time until you aim it, so you have to spend a lot of time until you are ready to shoot the novice archer. There are features that must be done.

If you shoot a bow with a high tension bow, the arrow's live height is low and the chance of flying close to normal is high. To shoot a bow with low tension, you can shoot a bow comfortably, but you have a high live and parabolic trajectory, so you are less likely to hit the target.

Therefore, after the arrow is released, the remaining energy is activated by the vibration of the bow to prevent human injuries, and the tension of the bow felt at the time of the bow is soft like a longbow. It is necessary.

1. The recurve bow is less powerful the first time you pull the bow, but it increases in strength until the end of the game, and you have to hold the right time to aim. To be present, there is a characteristic that requires a long time training. The graph curve in Figure 1 shows the tension distribution (characteristic of the bow) until the recurve bow is full.

2. In the case of compound bows, the maximum tension is applied until the cam camber (cam wheel) first returns to power (let-off), but it tends to be less powerful when full, so it is easier for beginners to shoot. There is this. The graph curve in Figure 2 shows the tension distribution (bow characteristics) of the compound bow until full bloom. Pulling a 60-pound compound bow to full length shows that you can aim with about 30 pounds of force, depending on the characteristics of the camwheel.

3. If you combine the recurve bow and the compound bow into one, the tension distribution is shown in Figure 3.

As shown in Figure 3, the composite of the recurve bow and compound bow shows the maximum function with 50 pounds of tension when the bow is about 27 inches long. In the case of Hansan-Re-pound-Bow, this characteristic is taken advantage of, and the tension is increased until full length, so the pulling taste is taken from the recurve bow, and the sum of the accumulated energy is the recurve bow. It is the sum of and the compound bow to create the most powerful and functional bow in human history.

Hereinafter, the accompanying drawings will be described in detail.

Figure 1 shows the components of the Hansan-Re-pound-Bow.

2. FIG. 2 is a general view of Hansan-Rep-ound-Bow.

Attach the compound bow rim ③ and the cam puller (cam wheel) ④ to the front (target side) of the handle ① of the recurve bow, and then hang the cam puller restoration line ⑧, The camouflage ⑥ is hung on the cam wheel, and the cam dorre (cam wheel) restoration line ⑧ is completely unrolled. Shows.

3. Fig. 3 shows the behavior of the bow during the full bloom of the Hansan-Re-pound-Bow.

If you draw the arrow ⑨ on the demonstration ⑥ and pull it to the full scale, the cam dorre (string) ⑦ will be pulled (unlocked on the cam wheel) and the cam wheel will rotate around the cam wheel support pin ⑩ to the outside of the bow. As soon as it rotates, the cam dorre (cam wheel) restoring line ⑧ is tensioned and wound around the inner cam wheel ⑤. As the wound, the compound rim ③ bends into the bow and accumulates force. Geogung? Masterpiece? When aiming and firing, the direction of the bending moment of both ends of the recurve bow rim and the direction of the bending moment received by the compound bow rim ③ are reversed so that the impact between each other is canceled and the elasticity is maximized.

Conventional recurve bows tend to be difficult when full-blown, and compound bows tend to have less force when full-blown, but the hand (the archer adapted to the recurve bow is unstable because of a looser pull). In both bows, the elastic force remaining after launching causes vibration to injure the human body and adversely affects sophisticated archery.

To solve this problem, attach a compound rim ③ and a cam puller (cam wheel) ④ to the front (target side) of the handle ① of the recurve bow, and then hang the cam puller restoration line ⑧, and demonstrate the cam pull (cam wheel) demonstration. )) Hanging the ⑦, bows (protest) ⑥ in order to be able to shoot an arrow, bows do not need a bow press,

When shooting the bow, the compound bow rim ③ and the cam wheel ④ are energized initially, and the recurve bow rim ② is applied when the bow is turned off as the bow is pulled out. ,

At the time of launching after full production, cam dole (cam wheel) ④ operates by the resilience of the compound bow rim ③ when the elasticity of the recurve bow rim ② decreases as time passes and the recurve bow rim ② decreases. While holding the arrow powerfully, the characteristics of the recurve bow + compound bow act at once with a time difference, so that the arrow can be blown powerfully.

Since the direction of movement of recurve bow rim ② and compound bow rim ③ is opposite to each other, the bending moments of ② and ③ act in the opposite direction to counteract the vibrations. It's easy and fun to shoot the bow, and the skilled spokesman makes for better archery.

Claims (1)

The recurve bow rim ②, the compound bow rim ③, and the cam dole (1) can be mounted on the handle ① so that the compound bow rim can be mounted on the front (the target side) of the bow and the recurve rim can be mounted on the rear (the arch side). After the cam wheel is mounted, hang the cam dorre restoring line ⑧, hang the cam dorre demonstration, and hang the bow ⑥ so that an arrow can be shown. Compound bow rim ③ is applied to the pull-off of the pulley, and the recurve bow rim ② receives a lot of force when the pulling distance is gradually increased. When (elasticity) acts and the elasticity of the recurve bow rim ② decreases as time passes, the cam dole (cam wheel) ④ is operated by the restoring force of the compound bow rim ③, and the arrow is strongly squeezed, and the recurve bow Compound Bow's characteristics are A bow that acts in a stroke, allowing you to shoot powerful arrows.
