DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 to 7, a first preferred embodiment of an improved dart game of this invention includes darts (7) with plastic tips and a dart board (D). The dart board (D) includes a base plate (1) and a target frame (4) fixed to the base plate (1) to (4) has a target portion (40), including concentric annular ribs (41a) and angularly spaced radial ribs (41b) which intersect the annular ribs (41a) to form a plurality of spaced scoring areas (41c) of different score values. An innermost annular rib (41a') forms a central circular scoring area (41c') which defines a bull's-eye section. Each of the annular and radial ribs (41a, 41b) has projecting studs (412) extending therefrom, as indicated in FIG. 4. Referring to FIG. 2, each of the annular and radial ribs (41a, 41b) has an enlarged front portion (411). The target frame (4) further has a plurality of target plates (5) of different shapes corresponding with and respectively disposed in the scoring areas (41c). The target plates (5) are mounted between the ribs (41a, 41b) and abut the enlarged front portion (411) to prevent untimely detachment from the target frame (4). The target plates (5) contact the projecting studs (412) and are shiftable rearwardly toward the base plate (1) along the projecting studs (412) with reduced friction.

Referring to FIGS. 5(A) to 5(C), each of the target plates (5) has a plurality of blind counterbores (51) formed thereon for receiving the dart (7). Each of the blind counterbores (51) includes an enlarged outer end formed with four inwardly tapered bevels (510) and a constricted inner end. Two adjacent blind counterbores (51) share a common peripheral edge on a front side of a respective one of the target plates (5). Only narrow peripheral edges are left between the blind counterbores (51). A dart (7) which strikes one of the target plates (5) tends to slide into one of the blind counterbores (51) rather than bounces away. Therefore, the blind counterbores (51) effectively capture the dart (7). In addition, each of the target plates (5) has at least one projecting stud (53) extending rearwardly toward the base plate (1). The number of projecting studs (53) on each target plate (5) corresponds to the area of the same.

The target frame (4) further includes an annular support member (55) which is fixed to the target portion (40) at the central circular scoring area (41c') by screws (59) and which defines an annular clearance with the innermost annular rib (41a'). The annular support member (55) has inner and outer elongated protrusions (551) extending inward and outward respectively and angularly spaced from one another. An inner circular target plate (54) is mounted in the annular support member (55) and has outer elongated grooves (541) which are angularly spaced from one another and which engage the inner protrusions (551). The inner circular target plate (54) is shiftable toward the base plate (1). An outer annular target plate (57) is mounted in the annular clearance between the annular support member (55) and the innermost annular rib (41a') and has inner elongated grooves (571) formed thereon which are angularly spaced from one another and which engage the outer protrusions (551). The outer annular target plate (57) is shiftable toward the base plate (1). Therefore, the inner circular target plate (54) and the outer annular target plate (57) define two scoring areas with two different score values in the bull's-eye section. This can make the game more challenging.

The dart board (D) further includes an automatic scoring register (R). The automatic scoring register (R) includes a flat panel (2) which is mounted in the hollow space between the base plate (1) and the target frame (4) and which is attached to the base plate (1). The flat panel (2) has a plurality of membrane switches (20) provided thereon which are arranged in accordance with the target plates (5). A circuit means (3), which includes a central processing unit, is mounted in the hollow space and is electrically connected to the membrane switches (20) by a bus (21). A display unit (U) includes four screens (43) covered with protecting covers (44) and two loud speakers (47). All of the screens (43) and the loud speakers (47) are electrically connected to and controlled by the circuit means (3). A switch unit (45), which has switch buttons, is mounted on the target frame (4) and is electrically connected to the circuit means (3).

A numeral panel (6) has a central hole (60) corresponding with the target portion (40), a plurality of angularly spaced numeral markings formed thereon and a protecting cover (62) covered thereon. The protecting cover (62) is made of a high density polymer material. The numeral panel (6) is mounted to the target frame (4) around the target portion (40).

A dart holding member (48) is mounted on the bottom end of the target frame (4) to hold the darts (7) when they are not in use.

The switch unit (45) is first turned on when the dart game of this invention is to be used. Referring to FIG. 6, a particular one of the target plates (5) is urged to shift inwardly toward the flat panel (2), and one of the studs (53) of the particular one of the target plates (5) momentarily impacts one of the membrane switches (20) when the dart (7) strikes the particular one of the target plates (5) and engages into one of the blind counterbores (51). The circuit means (3) is caused to control the screens (43) to show a score which corresponds to the particular one of the target plates (5) and to control the loud speakers (47) to recite the score.

Note that like elements are indicated by the same reference numerals throughout the disclosure. FIGS. 8 to 11 show a second preferred embodiment of this invention. The second preferred embodiment further includes a plurality of high density polymer plates (5') with detachable adhesive faces to be provided on a front side of a respective one of the target plates (5). The second preferred embodiment has a dart (7') with a metal tip to pierce into one of the high density polymer plates (5').

While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiments, but is intended to cover various arrangements included within the spirit and scope of the broadest interpretations and equivalent arrangements.
