Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 136 words
A battery housing, comprising a main body portion, a socket in said main body portion shaped to receive a battery, contacts disposed at one end of said socket for connection to correspondingly disposed electrodes on said battery, and a lid positioned to open and close over said socket, said lid including means for urging said battery electrodes into connection with said contacts, said means for urging comprising a latch for insertion into said socket at an end thereof opposite said contacts, said latch having an inward bend for forcing said battery toward said opposite end upon closing said lid, whereby said electrodes are urged into close connection with said contacts, and further including a resilient tab projecting from said lid at an acute angle thereto for forcing said battery into said socket upon closing said lid.
Claim 2
Dependent Claim 136 words
A battery housing, comprising a main body portion, a socket in said main body portion shaped to receive a battery, contacts disposed at one end of said socket for connection to correspondingly disposed electrodes on said battery, and a lid positioned to open and close over said socket, said lid including means for urging said battery electrodes into connection with said contacts, said means for urging comprising a latch for insertion into said socket at an end thereof opposite said contacts, said latch having an inward bend for forcing said battery toward said opposite end upon closing said lid, whereby said electrodes are urged into close connection with said contacts, and further including a resilient tab projecting from said lid at an acute angle thereto for forcing said battery into said socket upon closing said lid.
Claim 3
Dependent Claim 17 words
The battery housing of claim 1 wherein said lid is pivotally connected to said main body portion.
Claim 4
Dependent Claim 19 words
The battery housing of claim 1 wherein said lid includes an aperture for mounting said housing to a screw.
Claim 5
Dependent Claim 18 words
The battery housing of claim 1 wherein said main body portion is dimensioned to contain smoke alarm circuitry.
Claim 6
Dependent Claim 32 words
The battery housing of claim 1 wherein said main body portion is indented to receive said lid in closed position such that said lid and main body portion form a flat surface.
Claim 7
Dependent Claim 17 words
The battery housing of claim 1 wherein said socket conforms generally to a rectangular parallelepiped in shape.
Claim 8
Dependent Claim 35 words
The battery housing of claim 1 wherein said socket includes a cavity for receiving said latch, said latch being urged into connection with said cavity due to said inward bend being displaced by said battery.
Claim 9
Dependent Claim 19 words
The battery housing of claim 7 wherein said latch includes a tooth portion extending from a distal end thereof.
Claim 10
Dependent Claim 30 words
The battery housing of claim 8 wherein said cavity is bounded on one side by a surface against which said tooth portion rests for securing said lid upon closure thereof.
Claim 11
Dependent Claim 32 words
The battery housing of claim 1 further including a pair of differently sized rectangular slots in said socket for aligning said electrodes of the battery with like polarity ones of said contacts.
Claim 12
Dependent Claim 74 words
A battery housing, comprising a main body portion, a socket in said main body portion shaped to receive a battery, contacts disposed at one end of said socket for connection to correspondingly disposed electrodes on said battery, and a lid positioned to open and close over said socket, said lid including means for urging said battery electrodes into connection with said contacts, said lid including an aperture for mounting said housing to a screw.
Claim 13
Dependent Claim 74 words
A battery housing, comprising a main body portion, a socket in said main body portion shaped to receive a battery, contacts disposed at one end of said socket for connection to correspondingly disposed electrodes on said battery, and a lid positioned to open and close over said socket, said lid including means for urging said battery electrodes into connection with said contacts, said lid including an aperture for mounting said housing to a screw.
Claim 14
Dependent Claim 140 words
A battery housing, comprising a main body portion, a socket in said main body portion shaped to receive a battery, contacts disposed at one end of said socket for connection to correspondingly disposed electrodes on said battery, and a lid positioned to open and close over said socket, said lid including means for urging said battery electrodes into connection with said contacts, said means for urging comprising a latch adapted to be inserted into said socket at an end thereof opposite said contacts, said latch having an inward bend for forcing said battery toward said opposite end upon closing said lid, whereby said electrodes are urged into close connection with said contacts, said socket including a cavity for receiving said latch, said latch being urged into connection with said cavity due to said inward bend being displaced by said battery.
Claim 15
Dependent Claim 140 words
A battery housing, comprising a main body portion, a socket in said main body portion shaped to receive a battery, contacts disposed at one end of said socket for connection to correspondingly disposed electrodes on said battery, and a lid positioned to open and close over said socket, said lid including means for urging said battery electrodes into connection with said contacts, said means for urging comprising a latch adapted to be inserted into said socket at an end thereof opposite said contacts, said latch having an inward bend for forcing said battery toward said opposite end upon closing said lid, whereby said electrodes are urged into close connection with said contacts, said socket including a cavity for receiving said latch, said latch being urged into connection with said cavity due to said inward bend being displaced by said battery.
Claim 16
Dependent Claim 88 words
A battery housing, comprising a main body portion, a socket in said main body portion shaped to receive a battery, contacts disposed at one end of said socket for connection to correspondingly disposed electrodes on said battery, a lid positioned to open and close over said socket, said lid including means for urging said battery electrodes into connection with said contacts, and further including a pair of differently sized rectangular slots in said socket for aligning said electrodes of the battery with like polarity ones of said contacts.
Claim 17
Dependent Claim 88 words
A battery housing, comprising a main body portion, a socket in said main body portion shaped to receive a battery, contacts disposed at one end of said socket for connection to correspondingly disposed electrodes on said battery, a lid positioned to open and close over said socket, said lid including means for urging said battery electrodes into connection with said contacts, and further including a pair of differently sized rectangular slots in said socket for aligning said electrodes of the battery with like polarity ones of said contacts.
