Benefits of technology

The present invention provides a compound bow that minimizes twisting of the bow, exhibits inherent strength of the bow, and improves accuracy of an arrow. This is achieved by a bow main body with a handle and a pair of limbs, upper and lower pulleys, and cam cables that are wound on the pulleys. The cam cables are designed to have constant intervals and are supported by a spacing member to maintain a constant interval as the bowstring is pulled. The bow is designed to have improved accuracy and stability while in use.

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

[0040]Hereinbelow, a compound bow according to the present invention will be described in more detail with reference to the accompanying drawings.

[0041]Referring to FIGS. 4 to 12, a compound bow according to a first embodiment of the present invention comprises: a bow main body 300 including a pair of limbs 303 that are respectively coupled to both ends of a handle 302; upper and lower pulley assemblies 307 and 308 that are respectively coupled to the rear end of each limb 303; a bowstring 340; first and second cam cables 352 and 351 that are wound around a cam 400, 500 of each of the upper and lower pulley assemblies 307 and 308 as the bowstring 340 is pulled.

[0042]As shown, the compound bow according to the present invention will be described below in more detail. First, the bow main body 300 includes a handle 302 at a central portion of which a grip portion is formed so as to be gripped by a user, and a pair of limbs 303 that are respectively coupled to both ends of the handle 30...

second embodiment

[0077]In addition, when the first and second cam cables 353 and 354 in the second embodiment will be described, as shown in FIG. 13, the first cam cable 353 includes a first cable 353b, and a second cable 353a that is connected to the first cable 353b by a spacing member (a ring 700 in some embodiments of this invention), and the second cam cable 354 includes a first cable 354b, and a second cable 354a that is connected to the first cable 354b by a spacing member (a ring 700 in some embodiments of this invention). The first and second cam cables 353 and 354 have a vertically symmetric image.

[0078]Therefore, the first cam cable 353 will be described as an example. The second cable 353a in the first cam cable 353 is extended to the upper pulley assembly 308 and is wound around the cam cable winding portion 320 through which the rotating shaft 301 is penetrated in the upper pulley 310, and then the upper end of the second cable 353a is fixed to the fixing projection 530 formed in the u...

Abstract

Provided is a compound bow including: first and second cam cables between upper and lower pulley assemblies, wherein the lower cable of the first cam cable comprises: a one-side cable portion and the other-side cable portion on both sides of the pulley, in which either end of the lower cable is coupled to a fixing projection formed at either side of the pulley, and the one-side cable portion and the other-side cable portion of the lower cable are supported by a spacing member so as to maintain a constant interval, to thus make the one-side cable portion and the other-side cable portion of the lower cable wound on the respective cams formed at both sides of the pulley, while maintaining the one-side cable portion and the other-side cable portion of the lower cable to have the constant interval by the spacing member, as a bowstring is pulled.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Korean Patent Application No. 10-2015-0028183, filed on Feb. 27, 2015, in the Korean Intellectual Property Office, the disclosure of which is incorporated in its entirety herein by reference.FIELD OF THE INVENTION[0002]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.BACKGROUND OF THE INVENTION[0003]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.[0004]As shown in FIGS. 1 to 3, a conventional compound bow is configured to have upper limbs 20 that are coupled to the upper portion of a handle 10 at the ce...
