Abstract

A selective call receiver (100) comprises a battery powered receiver (104) for receiving and presenting a message, a battery having terminals for electrical coupling thereto, and a housing (208) enclosing the receiver (104) and the battery. The housing (208) has a first opening (206) for receiving the battery and at least one second opening (234) separate from the first opening (206) for securing a battery door (FIG. 4). The battery door (FIG. 4) provides access to the battery contained within the housing (208). The battery door (FIG. 4) comprises a hinged member (214) having a first end (238) coupled to the housing (208) for rotating between a closed position and an opened position, and a second end reduced to form a tongue (240). The hinged member (214) further includes a bottom surface (246) having an electrical contact (244) coupled thereto for electrically coupling the receiver (104) to the terminals of the battery and wherein the hinged member (214 ) rotates the electrical contact (244) pivotally away from the battery thereby breaking the electrical coupling therebetween. A movable member (212) coupled to and enclosing the hinged member (214) wherein the tongue (240) of the hinged member (214) is slidably coupled within a slot (250) of the movable member (212) for permitting the movable member (212) to slide along the hinged member (214) while the hinged member (214) remains stationary and coupled to the housing (208). The movable member (212) has a first end including at least one protrusion (228) for engaging to the housing (208) and a second end opposite to the first end has at least one strut (254, 256) for engaging with the at least one second opening (234) of the housing (208) for securing the movable member (212).

Claims

1. A selective call receiver comprising:

a battery powered receiver means for receiving and presenting a message;

a battery having terminals for electical coupling thereto;

a housing enclosing the receiver means and the battery, said housing having a first opening for receiving the battery and at least one second opening separate from the first opening for securing a battery door; and

said battery door providing access to the battery contained within the housing, said battery door comprising;

a hinged member having a first end coupled to the housing for rotating between a closed position and an opened position and a second end reduced to form a tongue, said hinged member further including a bottom surface having an electrical contact coupled thereto for electrically coupling said receiver means to the terminals of said battery and wherein said hinged member rotates said electrical contact pivotally away from the battery thereby breaking the electrical coupling therebetween; and

a movable member coupled to and enclosing said hinged member wherein the tongue of the hinged member is slidably coupled within a slot of said movable member for permitting the movable member to slide along said hinged member while said hinged member remains stationary and coupled to said housing, said movable member having a first end including at least one protrusion for engaging to said housing and a second end opposite to said first end having at least one strut for engaging with the at least one second opening of said housing for securing said movable member.

2. The selective call receiver according to claim 1 wherein the battery door having the hinged member is pivotally coupled to the housing.

3. The selective call receiver according to claim 1 wherein the housing includes a lock for coupling to the movable member for locking the battery door to the housing.

4. A selective call receiver according to claim 1 wherein the hinged member of the battery door maintains a non-movable contact with a battery while the movable member engages and disengages the battery door to and from the housing.

5. The selective call receiver according to claim 1 wherein the movable member moves parallel along the hinged member.

6. A battery door for securing a battery within a selective call receiver comprising:

a) a hinged member and movable member;

b) the hinged member having a first end coupled to a housing of the selective call receiver for providing access to a battery within the housing and a second end reduced to form a tongue for coupling slidably with the movable member, said hinged member including a bottom surface having a battery contact spring for electrically coupling to the battery and wherein said hinged member rotates said battery contact spring pivotally away from the battery thereby breaking an electrical coupling therebetween, said housing having a first opening for receiving the battery and at least one second opening separate from the first opening for securing the movable member;

c) the movable member coupled to and enclosing said hinged member wherein said tongue of said hinged member is slidably coupled within a slot of said movable member for permitting the movable member to slide along said hinged member while said hinged member remains stationary and coupled to the housing, said movable member having a first end including at least one protrusion for engaging to said housing and a second end opposite to said first end having at least one strut for engaging with the at least one second opening of said housing for securing said movable member;

d) said battery contact spring coupled to the hinged member provides a non-movable electrical contact while permitting the movable member for slidably engaging and disengaging the battery door from the housing.

7. A method for securing a battery within a selective call receiver comprising the steps:

a) sliding a movable member coupled to and enclosing a hinged member for engaging and disengaging said movable member with a housing of the selective call receiver, said housing having a first opening for receiving the battery and at least one second opening separate from the first opening for securing a battery door comprising the movable member and the hinged member; and

b) rotating the hinged member coupled to the housing of the selective call receiver for providing an electrical contact to the battery, said step of rotating rotates said hinged member pivotally away from the battery thereby preventing a slidable movement between said battery and an electrical contact spring coupled to a bottom surface of said hinged member for providing the electrical contact to the battery;

(c) engaging a tongue formed at one end of the hinged member to a slot of the moveable member for slidably coupling the movable member to the hinged member to provide a parallel movement of said moveable member along the hinged member; and

(d) locking the movable member to the housing wherein said movable member having a first end including at least one protrusion for engaging to said housing and a second end opposite to said first end having at least one strut for engaging with the at least one second opening of said housing for securing said movable member of the battery door and the battery within the housing.
