Abstract

A barrel for a dart includes a plurality of weights 23 each of which having a protrusion 24 on an end thereof and having a recess 25 on the other end thereof. A cap 21 connected with a point 10 has a recess 22 on an end distal to the point which receives the protrusion of the weight. A shaft 30 has a flight 31 formed on a first end thereof, and a protrusion formed on a second end thereof which can be inserted into the recess 25 of abutting weight 23. The weights, cap and shaft may be threaded together or the point may have a threaded end (12 fig 4) engaging a threaded hole (301 fig 4) in the shaft, the point passing through axial holes (211, 231 fig 4) in the cap and weights and holding the assembly together with a cone part (13 fig 4). <IMAGE>

Description

BARREL FOR A DART The present invention relates to a barrel for a dart, more particularly, to a barrel with a plurality of weights whose members can be varied to adjust the location of mass center thereof, obtaining a steady flight.

A dart now in use generally includes a point, a barrel, a shaft and a flight and has a fixed mass center. For players having different habits in handling the dart, it is always annoying to have to find out the best grasping point in the case that the dart now at hand differs from a usually used dart in the length or weight. The present invention provides an improved dart to mitigate and/or obviate the above problem.

The present invention provides a barrel for a dart which includes a plurality of weights fitted before a point and on an end of a shaft to allow adjustment of the location of mass center of the dart.

It is an object of the present invention to provide a barrel for a dart comprising a plurality of weights which are fitted on an end of the shaft to fit player's need to set the location of the mass center of a dart.

Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

In the drawings: Fig. 1 is a perspective view of a dart in accordance with the present invention; Fig. 2 is an exploded view of the dart, in Fig. 1; Fig. 3 is a partial side elevational view, partly in section, of the dart in Fig. 1; Fig. 4 is an exploded view illustrating another embodiment of a dart in accordance with the present invention; and Fig. 5 is a partial side elevational view, partly in section, of the dart shown in Fig. 4.

Referring to the drawings and initially to Figs. 1, 2 and 3, a dart in accordance with the present invention includes a point 10, a barrel 20, a shaft 30 and a flight 31.

The point 10 has a first sharp end to penetrate a target and a second end. The barrel 20 comprises a cap 21 and a plurality of weights 23, the cap 21 having a reception hole 210 formed in a cone-shaped end thereof, and a first threaded recess 22 formed in the other end thereof. Each of the weights 23 includes a body with a diameter the same as the greatest diameter of the shaft 30 which tapers rearwardly to the flight 31, a first thread stub 24 extends outwardly from an end of the body and a second threaded recess 25 is formed in the other end thereof. The shaft 30 has first and second ends, the first end distal to the point 10 is connected with the flight 31, the second end having a second threaded stub 32 extending outward therefrom. The flight 31 comprises a plurality of fins 311 extending radially outward from the first end of the shaft 30.

Players can choose suitable number of weights 23 which fit the habit of grasping the dart and combine the weights 23 to the barrel 20, the point 10, the shaft 30 and the flight 31 to set a dart with certain length and mass center.

When setting up the dart, players insert the second end of point 10 into the reception hole 210 of the cap 21 and the first sharp end extending outward thereof, the weights 23 being connected to the cap 21 by screwing the first threaded stub 24 into the first threaded recess 22 of the cap 21, other weight 23, if needed, screwing the first threaded stub 24 into the second threaded recess 25 of an antecedent weight 23. Then the weight 23 abutting the second end of the shaft 30, being engaged to the shaft 30 by screwing the second threaded stub 32 of the shaft 30 into the threaded recess 25 thereof to set a dart.

Figs. 4 and 5 show another embodiment of a dart of the present invention including a point 10 which is a rod with a first sharp end, a second threaded insert portion 12, and a cone part 13 formed on the rod and having two protrusions 11 projecting from a flat bottom surface thereof. A cap 21 has a through hole 211 along an axis thereof and two notches 212 are formed in the cap 21, each notch adjacent to hole 211 for receiving the protrusions 11. A first recess 22 is formed in an end distal to the cone-shaped end thereof. Weight 23 is a body with a diameter the same as the greatest diameter of the shaft 30 which tapers rearwardly to the flight, a first part 24 extending outward from a side thereof which can be inserted into the first recess 22 of the cap 21, and a second recess 25 is formed on the other end of the body.A through hole 231 extending along the axis of the weight 23 is formed aligned with the through hole 211 of the cap 21 when fitted together. A shaft 30 has first and second end, the first end is connected with a flight 31, and the second end has a second part 32 formed extending outwardly thereof, the second part 32 can be fitted into the second recess 25 to connect to the abutting weight 23. A threaded hole 301 is formed along the axis in the second part 32 in alignment with through hole 231. When setting up the dart, players choose the weights 23 which are needed and connects them to each other by fitting the first part 24 of a weight 23 into the second recess 25 of another weight 23 thereof, then inserting the first part 24 of the weight 23 abutting the cap 21 into the first recess 22 of the cap 21. After that, extending the insert portion 12 of the point 10 through the hole 211 of the cap 21 and the holes 231 of the weights 23, the protrusions 11 are then received in the notches 212 of the cap 21 and the under portion of the cone part 13 abuts the cap 21 to form a cone configuration. By this arrangement, players can screw the insert portion 12 into the threaded hole 301 of the shaft 30 by rotating the cap 21 instead of the point 10 this results in convenient' operation for grasping.

Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claim.
