  Magnetic induction dartUSPTO Application #: 20070080498Title: Magnetic induction dart Abstract: A dart comprises: a body, a shaft, a flight, a tip, and a magnetic member. The body is formed with a receiving space, the magnetic member is detachably disposed in the receiving space of the body and is located between the body and the shaft. The tip is made of magnetic induction material. The magnetic member can be assembled and disassembled easily, and the magnetic induction material of the tip is attracted by the magnetic member to produce lines of magnetic force.

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a magnetic induction dart to be used with a dartboard with induction coils to create a score. [0003] 2. Description of the Prior Art [0004] The electronic scoring dartboards currently on the market are generally classified into tactile type and magnetic induction type. [0005] U.S. Pat. No. 5775694 discloses a magnetic dart as shown in FIG. 1, wherein the body 10 of the dart is made of non-magnetic induction material, in the front end of the body 10 is inserted a strong magnetic member 11 that protrudes therefrom, and an electromagnetic induction dartboard is used to record the score automatically. The aforementioned magnetic dart still has the following disadvantages: [0006] First, there is no scoring tip on the front end of the body 10, therefore, this conventional dart cannot be used in formal competition. [0007] Second, the generated lines of magnetic force will be densely and radially congregated at the front end of the body 10 in a semicircular pattern, and the width of the semicircular pattern of the lines of magnetic force is very large. Therefore, it will cause false induction on the electromagnetic induction dartboard to create a false score. [0008] Third, there is no scoring tip on the front end of the body 10, therefore, the player can't experience the penetrating strength when throwing dart, and the dart game gives the player no pleasure. [0009] Fourth, strong magnetism has adverse effect on the health of the player. [0010] The present invention has arisen to mitigate and/or obviate the afore-described disadvantages. SUMMARY OF THE INVENTION [0011] The primary objective of the present invention is to provide an easily assembled and disassembled magnetic induction dart, the magnetic member is detachably disposed in the receiving space of the body of the dart and is located between the shaft and the body. Therefore, the magnetic member can be assembled and disassembled easily and quickly by the user. [0012] The secondary objective of the present invention is to provide a magnetic induction dart. A magnetic member is embedded in the body, and the tip is made of magnetic induction material. The magnetic induction material produces circle circulatory lines of magnetic force by the indirect induction of the lines of magnetic force of the magnetic member. By such arrangements, the induction coils of the dartboard can accurately sense the lines of indirect magnetic induction, without being affected by the strong and dense lines of magnetic force of the strong magnetic member. BRIEF DESCRIPTION OF THE DRAWINGS [0013] FIG. 1 is an illustrative view of showing a conventional dart; [0014] FIG. 2 is an exploded view of a dart in accordance with the present invention; [0015] FIG. 3 is an assembly view of the dart in accordance with the present invention; [0016] FIG. 4 is an illustrative view in accordance with the present invention of showing the lines of magnetic induction; [0017] FIG. 5 shows a part of the magnetic induction dartboard in accordance with the present invention; [0018] FIG. 6 shows a dart in accordance with a second embodiment of the present invention; and [0019] FIG. 7 shows a dart in accordance with a third embodiment of the present invention; and [0020] FIG. 8 shows a dart in accordance with a fourth embodiment of the present invention.
