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.
