AI Technical Summary

Benefits of technology

The present invention is a compound bow that helps prevent the bow from twisting during use. This results in a stronger bow that is easier to use and improves the synchronizing of the bow, which makes the arrow more accurate.

Problems solved by technology

As a result, the inherent strength of the bow is not exhibited and the accuracy of the arrows is also dropped.

first embodiment

[0035]Hereinbelow, a compound bow according to the present invention will be described in more detail with reference to the accompanying drawings.

[0036]FIG. 4 is a side view showing a compound bow according to a first embodiment of the present invention before a bowstring is pulled. FIG. 5 is a detailed view of a pulley assembly that is coupled to one of limbs in FIG. 4. FIG. 6 is a side view showing a compound bow according to the first embodiment of the present invention after a bowstring has been pulled. FIG. 7 is a detailed view of a pulley assembly that is coupled to one of limbs in FIG. 6. FIG. 8 is a front view of the pulley assembly of FIG. 7 seen from the front side of the compound bow.

[0037]Referring to FIGS. 4 to 8, a compound bow according to a first embodiment of the present invention includes: a bow main body 100 including a handle 102 at a central portion of which a grip portion is formed and a pair of limbs 103 that are respectively coupled to both ends of the handle...

second embodiment

[0065]FIG. 10 is a detailed view of a pulley assembly that is coupled to one of limbs in FIG. 9. FIG. 11 is a side view showing a compound bow according to the present invention after a bowstring has been pulled. FIG. 12 is a detailed view of a pulley assembly in FIG. 11. FIG. 13 is a side view of the pulley assembly of FIG. 12 seen from the rear side of the compound bow.

[0066]The description of the compound bow according to the second embodiment of the present invention focuses on a different configuration from the description of the first embodiment of the present invention. In the compound bow according to the second embodiment of the present invention, the cam 200 is coupled to one side of each pulley 110 and is rotated with rotation of the pulley 110 to thus make the cam cables 150a and 150b wound on the cam 200, and includes: a cam cable winding portion 210 fabricated in an arc-shaped form and on which the cam cables 150a and 150b are wound; and a cam module 220 that is rotata...

Abstract

A compound bow includes a bow main body including a handle and a pair of limbs. Upper and lower pulleys are coupled to the rear end of each limb. A bowstring is provided and a cam that is coupled to each pulley. A rotating wheel is coupled with the rotating shaft of the pulley. Cam cables are wound around the cams, in which one end of each cam cable is coupled to one pulley and the other end thereof is coupled to the other pulley. A cam cable guide member has one end rotatably coupled to the rotating shaft of the pulley, and at the other end of which a support member for supporting the cam cable is formed in order to make a portion of the cam cable extended from the rotating wheel guided in parallel with the pulley.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of Korean Patent Application No. 10-2013-0100228, filed on Aug. 23, 2013 and No. 10-2013-0164958, filed on Dec. 27, 2013 in the Korean Intellectual Property Office, the disclosures of which are incorporated in their entireties herein by reference and to which priority is claimed.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a compound bow, and more particularly, to a compound bow which can prevent distortion of the bow and improve accuracy of an arrow when a bowstring is pulled.[0004]2. Description of the Related Art[0005]Typically, compound bows are configured so that a bowstring may be easily pulled without using a large force and arrow shooting power is increased during shooting, by using an effect of a cam or wheel, to thus result in a fast speed of an arrow and have very strong power, and are widely used mainly for hunting.[0006]As shown in FIGS. 1 ...
