Abstract
A dart board includes a backing plate with a frame connected thereto and a plurality of ribs on the frame so as to define a plurality of partitions in which a plurality of blocks are movably received respectively. Each block has flexible convex portions which contact an inside of the ribs defining the partition when the block is hit by darts. A plurality of spring members are connected between the backing plate and the blocks so as to bounce the blocks back after the impact disappears.
Description
FIELD OF THE INVENTION
The present invention relates to a dart board that does not generate noise when the blocks are hit by the darts.
BACKGROUND OF THE INVENTION
A conventional dart board is shown in FIG.
6
and generally includes a frame
10
which is connected on a backing plate
13
and a plurality of electronic members
12
are connected on the backing plate
13
. The frame
10
includes a plurality of partitions separated by ribs on the frame
10
and each partition receives a block
11
therein. A dart
14
hits one of the blocks
11
and the block
11
being hit moves toward the backing plate
13
and activates the electronic members
12
so as to display scores that the throw gains. It is necessary to maintain a gap between the inside of the partitions and the blocks
11
so that the blocks
11
are allowed to move toward the backing plate
13
. Nevertheless, noise is generated when the block
11
is moving and the impact between the blocks
11
and the frame
10
no matter what material is used to make the block
11
. Besides, other blocks
11
that do not hit could shake and generate noise. The noise really reduces the feeling of entertainment of the players.
SUMMARY OF THE INVENTION
The present invention relates to a dart board which comprises a backing plate and a frame is connected to the backing plate. A plurality of ribs extend from the frame to define a plurality of partitions in which a plurality of blocks are movably received respectively. Each block has flexible convex portions which contact an inside of the ribs defining the partition. A plurality of spring members are connected between the backing plate and the blocks.
The primary object of the present invention is to provide a dart board that generates no noise when the darts hits the blocks.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1
is an exploded view to show a block member and a casing of the dart board of the present invention;
FIG. 2
is an exploded view to show the dart board of the present invention;
FIG. 3
is a cross sectional view to show the dart board of the present invention;
FIG. 4
shows that a dart hits the block member of the dart board of the present invention;
FIG. 5
is a top view to show that the block member received in the casing is engaged in a partition of the dart board of the present invention, and
FIG. 6
shows a dart hits a block of a conventional dart board.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to
FIGS. 1
to
3
, the dart board of the present invention comprises a backing plate
20
and a frame
30
is connected to the backing plate
20
. A plurality of ribs
31
extend from the frame
30
and define a plurality of partitions
32
in various areas. An electronic plate
21
is connected to the backing plate
20
and located between the frame
30
and the backing plate
20
.
A plurality of blocks
40
are movably received in the partitions
32
respectively and each block
40
comprises a casing
41
in which a block member
42
is received from an open top of the casing
41
. Each casing
41
has a flexile peripheral wall
412
which is expanded by the block member
42
to be the convex portions
43
which contact an inside of the ribs
31
defining the partition. The block members
42
each are made by artificial fibers which are force-fitted in the casing
41
so as to expand the flexible peripheral wall
412
to be the convex portions
43
. Each casing
41
has protrusions
44
extending from an underside thereof.
A plurality of spring members
50
are connected between the backing plate
20
and the blocks
40
. The springs
50
each have a plurality of bosses
51
extending therefrom and electronic pads
52
are sandwiched between each of the bosses
51
and the protrusions
44
. The electronic pads
52
are electrically connected to the electronic plate
21
.
Referring to
FIGS. 4 and 5
, when the block
40
is hit by a dart
80
, the block
40
moves toward the backing plate
20
and the convex portions
43
contact the ribs
31
defining the partition
32
that the block
40
is received during the movement. The block
40
does not shank or impacts the ribs
31
so that noise is not generated. After the impact disappears, the spring member
50
pushes the block
40
back to its original position.
It is to be noted that the block member
42
and the casing
40
can be made to be a one-piece member. The convex portions
43
are still flexible and absorb noise during the movement of the blocks
40
.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
Claims
- 1. A dart board comprising:a backing plate and a frame connected to the backing plate, a plurality of ribs on the frame and a plurality of partitions defined by the ribs; a plurality of blocks movably received in the partitions respectively and each block having flexible convex portions which contact an inside of the ribs defining the partition, each block comprising a casing in which a block member is received, each casing having a flexile peripheral wall which is expanded by the block member to be the convex portions, and a plurality of spring members connected between the backing plate and the blocks.
- 2. The dart board as claimed in claim 1, wherein the springs each have a plurality of bosses extending therefrom which contact the block mounted thereto.
- 3. The dart board as claimed in claim 1, wherein the springs each have a plurality of bosses extending therefrom and each casing has protrusions extending from an underside thereof, the bosses contacting the protrusions.
- 4. The dart board as claimed in claim 3 further comprising a plurality of electronic pads sandwiched between each of the bosses and the protrusions.
