(57) A dartboard consists of a disc (10) divided into target zones by exposed edges of
thin strips of metal (12) disposed or embedded in slots (11), the exposed edges preferably
lying substantially flush with the surface (13) of the disc.

[0001] This invention relates to a target, such as a dartboard.
[0002] A conventional dartboard has a surface mounted wire frame which sub-divides the board
into discrete target zones. This frame, and the staples fixing the frame to the board,
are often the cause of darts bouncing off the board, particularly near the centre
where the wires are close together. On the other hand, if the target zones are merely
indicated visually, for example by painting the zones different colours, disputes
can arise over which zone a dart or other missile has entered.
[0003] According to the present invention the border of at least one target zone in a target
is formed by an exposed edge of a thin strip of impenetrable material embedded in
the target. The exposed edge preferably lies substantially flush with the surface
of the target, and is preferably chamfered, sharpened or radiused. The impenetrable
strip material is preferably metal.
[0004] The target is preferably formed of a material capable of receiving and releasably
retaining a missile, such as a dart aimed at the target. The embedded strip may extend
either partly through the thickness of the target, or it may extend completely through
the target so that the target is divided into discrete segments.
[0005] Preferably the borders of each target zone are formed by the exposed edges of such
strips, and the strips combined to form a one-piece frame. The frame is then either
slotted into a target board, or the target is formed as an assembly of discrete segments
which fit into the frame. In the latter case, further means are provided to hold the
assembled segments together. The latter arrangement has the advantage that the discrete
segments can be rotated or interchanged to allow for localised wear.
[0006] Two examples of the invention are illustrated in the accompanying drawings in which:
FIG. 1. is a part-section through a dartboard embodying the invention,
FIG. 2. is a part-section through an alternative dartboard embodying the invention,
and
FIG. 3. is a section through three possible metal strips for use in the embodiments
of Figs. 1. and 2.
[0007] In FIG.l. a dartboard 10 consists of a thick circular disc formed of any material
which will receive and releasably retain the point of a dart. Suitable materials would
be a plastics foam, felt, cork, or a composite.
[0008] The disc is provided with slots 11 which divide the board 10 into the conventional
target zones of a dartboard. Metal strips 12 are inserted into the slots 11, the strips
12 being joined to one another to form a one-piece frame. The strips fit tightly in
the slots and are therefore held in the slots by the resiliency of the material forming
the board 10. The top edge of each strip lies substantially flush with the surface
13 of the board 10.
[0009] In FIG. 2 like parts are denoted with like reference numerals. The only difference
between Figs.l and 2 is that in Fig. 2 the strips 12 extend through the whole thickness
of the board 10 from the front surface 13 to the back surface 14. The board is thus
split into discrete segments, and these segments are held together within a tray 15
or in any other suitable manner.
[0010] In either embodiment, the top edges of the strips 12 may be rounded, as shown in
Fig. 3a, provided with a double chamfer as shown in Fig. 3b, or square as shown in
Fig. 3c. The strips have a thickness of ,approximately 0.5.mm.
1. A target comprising at least one layer of material for receiving and releasably
retaining a missile, such as a dart, the missile-receiving surface being divided into
a plurality of target zones, and the border of at least one target zone being formed
by an exposed edge of a thin strip of substantially impenetrable material disposed
or embedded in the layer or layers.
2. A target according to Claim 1 in which the exposed edge lies substantially flush
with the missile-receiving surface of the target.
3. A target according to Claim 1 or Claim 2 in which the exposed edge is chamfered,
sharpened or radiused.
4. A target according to any one of the preceding claims in which the strip is a metal
strip.
5. A target according to any one of the preceding claims in which the strip extends
only part way through the thickness of the layer or layers.
6. A target-according to any one of the Claims 1 to 4 in which the strip extends completely
through the layer or layers such that the layer or layers are divided by the strip
into discrete segments.
7. A target according to Claim 1 in which the borders of each zone are formed by exposed
edges of such a strip, and wherein the strips are combined to form a one-piece frame.
8. A target according to Claim 7 in which the frame is slotted into the said layer
or layers of target material.
9. A target according to Claim 7 in which the target zones are formed as discrete
segments which fit into the frame.
10. A target according to Claim 9 further comprising means for holding the assembled
segments together.
