  • Patent number: 6524201
    Abstract: A dart includes a barrel, having a blind bore opening into one, or preferably both, ends, the bore closed by a threaded end cap with a passage therethrough, a shaft slidably received in the passage and retained in the bore by an enlarged collar at one end, and an elastomeric cylinder spring bearing against the end of the bore and the collar, to bias the shaft away from the barrel. The shaft may be either a forward scoring pin, or rearward flight shaft. The bore is of a larger diameter than the elastomeric cylinder, to allow compressional flexural movement of the shaft in response to forces imposed on the shaft and barrel, to reduce rejection of the shaft into a dart board, and reduce deflection of subsequently thrown darts which strike the rear shaft, The dart may include a hollow interior to receive a customizable weight body, and a detachable indented grip.

  • Patent number: 6277041
    Abstract: A dart is disclosed which includes a flexibly mounted point and flight shaft. The dart includes a central tubular body which has fore and aft end caps. The fore cap includes a central bore, a forward through bore, and a socket therebetween. A point is mounted in a carrier, which is received in the central bore of the fore cap and seats in the socket. An elastomeric spring cylinder biases the carrier forward so the point is normally located along the dart axis. Upon impact with a target, the point can move longitudinally and, in some embodiments, pivot under compression against the spring cylinder, to reduce the chance of dart rejection if it strikes a target impediment or divider. The rear flight shaft can be mounted in a manner similar to the point, so the dart flights have reduced tendency to deflect other incoming darts. The central body includes an adjustable weighting arrangement.

  • Publication number: 20010014635
    Abstract: A toy dart, as a thrown projectile, is created by end-user determinates towards the personalization of various internal embodiments, those values being noted forwardly and aftwardly of a weight/s chamber/s therebetween if the latter is so desired. The primary controlling factor, involving both compressional movement and stabilization, is a cylindrical column that can be called a rubber spring; where, axial and/or to non-axial motion relative to impact controls is a locus constrained by mass/time/length about the focal points thereto. Forwardly, in a partial bore and threadable endcap of the barrel of this dart, that rubber column involves transfer management that eliminates rejection caused by intersectional criteria. Aftwardly, against a similar arc of travel, those attributes are managed so as to eliminate deflection due to the intended dispersion of that arcuate involved lateral/mass iteratives.
