Abstract
Abstract A single molded plastic part forms the actuator, the latching beam and the retainer for holding the latch mechanism in position, and also provides detented open and closed positions. The latch mechanism can be used with the door or closure for an opening in a housing, such as the battery door for a small portable electronic device. The one-part latch has an actuating button on one side of the door which cooperates with resilient retainer tabs to hold the latch in movable engagement with the door. An integral latching beam may extend on the other side of the door and be movable to a position to latch the door. Indentations on the beam, or on another part of the latch, can cooperate with a detent cam to hold the latch mechanism in released or open, and latched or closed positions. The latch mechanism can be either slidably or rotatably movable for the latching operation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
147 words
A one-piece springless fingerlike latch mechanism for use on a portable, hand-held device having a housing and a door movable in relation thereto and wherein the door is slidable between first and second positions and has an opening therein, such latch mechanism including in combination: an actuating portion on one side of the slidable door for operating the latch mechanism in lateral rectilinear movement; a coupling portion connected to said actuating portion and extending through the opening in the slidable door, and said coupling portion having resilient ribs engaging the opposite side of the slidable door for holding the latch mechanism in said rectilinearly movable relation on the slidable door; and a springless latching portion formed integrally with said actuating portion and said coupling portion, and laterally slidable by said actuating portion between a first set released position and a second set latched position engaging the housing.
Claim 2
Dependent Claim
147 words
A one-piece springless fingerlike latch mechanism for use on a portable, hand-held device having a housing and a door movable in relation thereto and wherein the door is slidable between first and second positions and has an opening therein, such latch mechanism including in combination: an actuating portion on one side of the slidable door for operating the latch mechanism in lateral rectilinear movement; a coupling portion connected to said actuating portion and extending through the opening in the slidable door, and said coupling portion having resilient ribs engaging the opposite side of the slidable door for holding the latch mechanism in said rectilinearly movable relation on the slidable door; and a springless latching portion formed integrally with said actuating portion and said coupling portion, and laterally slidable by said actuating portion between a first set released position and a second set latched position engaging the housing.
Claim 3
Dependent Claim
27 words
The structure of claim 1 wherein said latch mechanism has portions cooperating with the slidable door forming detents which define the set released and set latched positions.
Claim 4
Dependent Claim
24 words
The structure of claim 1 wherein said latching portion extends from said coupling portion and is on the opposite side of the slidable door.
Claim 5
Dependent Claim
32 words
The structure of claim 1 wherein said coupling portion is rectilinearly slidable in the opening of the slidable door, and said latching portion is a latch beam adapted to engage the housing.
Claim 6
Dependent Claim
24 words
The structure of claim 4 wherein said latch beam has indentations therein forming detents for holding the latch mechanism in released and latched positions.
Claim 7
Dependent Claim
104 words
A door and latch combination for a portable, hand-held device including in combination: a door slidably movable between first and second positions and having a relatively flat portion with an opening therein; and a one-piece springless latch member laterally slidable in rectilinear movement within said opening and having an integral actuating portion on one side of said door and an integral fingerlike latching portion on the opposite side of said door, wherein said door has a detent cam thereon, and said fingerlike latch member has portions cooperating with said cam to hold said latch member in first set released and second set latched positions.
Claim 8
Dependent Claim
104 words
A door and latch combination for a portable, hand-held device including in combination: a door slidably movable between first and second positions and having a relatively flat portion with an opening therein; and a one-piece springless latch member laterally slidable in rectilinear movement within said opening and having an integral actuating portion on one side of said door and an integral fingerlike latching portion on the opposite side of said door, wherein said door has a detent cam thereon, and said fingerlike latch member has portions cooperating with said cam to hold said latch member in first set released and second set latched positions.
Claim 9
Dependent Claim
41 words
The structure of claim 6 wherein said fingerlike latch member has integral resilient retainer tabs engaging said opposite side of said slidable door cooperating with said actuating portion to hold said latched member in a laterally slidable relation on said door.
