Abstract
A dart board assembly includes a fixed member connected to a dart board and pivotally connected to a door. A spring member is connected to the fixed member and is engaged with a first plain surface on a first side of the hinge member when the door is at open position to secure the open status. The spring member is engaged with a second plain surface on a second side of the two hinge members when the door is at close position.
Description
FIELD OF THE INVENTION
The present invention relates to a dart board assembly having two doors wherein the hinge means connected between the doors and the dart board includes a flexible plate which alternatively engages with two plain surfaces on the hinge members at open and close position.
BACKGROUND OF THE INVENTION
A conventional dart assembly is shown in FIG.
7
and generally includes a dart board which is enclosed in a frame
10
. Two doors
11
are respectively and pivotally connected to two sides of the frame
10
by two pairs of hinges
12
. A magnet
14
is connected to a top of the frame
10
and each door
11
has a metal piece
13
which can be connected to the magnet
14
when the doors
11
are at close position. The doors
11
are designed to protect the dart board from being accessed by dirt or unexpected objects. Nevertheless, the doors
11
cannot be secured at their positions when the metal pieces
13
on the two doors
11
are connected to the magnet
14
because once the metal pieces
13
are separated from the magnet
14
, the doors
11
are at a free status and fail to achieve the desired purpose. Actually, the force to connect the metal pieces
13
to the magnet
14
is limited so that the doors are unstable during transportation.
The present invention intends to provide a hinge means between a door and a dart board wherein a spring member is biased on one of two plain surfaces on the hinge member on the door so as to keep the door at open position or close position.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a dart board assembly comprising a fixed member connected to a dart board and a door pivotally connected to the dart board. The door has a hinge member and is pivotally connected to the fixed member. A spring member is connected to the fixed member and engaged with a first side of the hinge member when the door is at open position. The spring member is movably engaged with a second side of the hinge member when the door is at close position.
The object of the present invention is to provide a dart assembly with doors wherein a spring member is engaged with the hinge members to keep the doors at open position or close position as desired.
These and further objects, features and advantages of 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, several embodiments in accordance with the present invention.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1
is an exploded view to show a hinge means for a dart board assembly of the present invention;
FIG. 2
is a perspective view to show a door is pivotally connected to the dart board by the hinge means of the present invention;
FIG. 3
is a plan view to show the hinge means when the door is at close position;
FIG. 4
is cross-sectional view to show a spring member is engaged with a first plain surface of the hinge means when the door is closed;
FIG. 5
is a plan view to show the hinge means when the door is at open position;
FIG. 6
is cross-sectional view to show a spring member is engaged with a second plain surface of the hinge means when the door is opened, and
FIG. 7
is a perspective view to show a conventional dart board assembly with two opened doors.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to
FIGS. 1
to
4
, the dart assembly in accordance with the present invention comprises dart board
21
which is enclosed by a frame
20
and two doors
40
(only one is shown) is pivotally connected to a side of the frame
20
. The frame
20
has a recess
22
defined in the side thereof and a fixed member
30
is received in the recess
22
. The fixed-member includes a body
31
and a tongue
32
extending from a mediate portion of the body
31
. The body
31
is received in the recess
22
and has two threaded holes
311
. A spring member
50
is securely connected to the body
31
and received in the recess
22
. Two bolts
60
extend through the frame
20
, two holes
511
in the spring member
50
and are engaged with the threaded holes
311
in the body
31
of the fixed member
30
. The tongue
32
has a hole
321
defined therethrough.
The door
40
has two hinge members
41
extending from a side of the door
40
and each hinge member
41
has a passage
411
defined therethrough so that the tongue
32
is pivotally connected between the two hinge members
41
by extending a pin
42
through the passages
411
of the two hinge members
41
and the hole
321
of the tongue
32
. The spring member
50
has two extensions
52
and the tongue
32
is movably located between the two extensions
52
. The extensions
52
are movably engaged with a first side of the two hinge members
41
when the door
40
is at open position, and the extensions
52
are movably engaged with a second side of the two hinge members
41
when the door
40
is at close position.
Each hinge member
41
has a first plain surface
413
on the first side thereof and the extensions
52
are engaged with the first plain surfaces
413
of the hinge members
41
as shown in
FIGS. 5 and 6
. The spring force of the two extensions
52
applying on the first plain surfaces
413
prevents the door
40
from being pivoted toward the dart board
21
. Each hinge member
41
has a second plain surface
412
on the second side thereof and the extensions
52
are engaged with the second plain surfaces
412
of the hinge members
41
as shown in
FIGS. 3 and 4
. The spring force of the two extensions
52
applying on the second plain surfaces
412
prevents the door
40
from being pivoted away from the dart board
21
. As shown in
FIGS. 3 and 4
, when closing the door
40
, the hinge members
41
are rotated about the pin
42
and the two extensions
52
slide over a rounded end
415
connected between the first plain surface
413
and the second plain surface
412
.
While we have shown and described various embodiments 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 and spirit of the present invention.
