Abstract
Abstract A battery retention latch (50, 140) comprises an annular ring member (52, 142), a release button (54, 172, 174) and a spring arm (156, 190, 192, 194, 196). The annular ring (52, 142) retains a battery pack (26) in a cordless device (20, 120) regardless of the annular orientation of the battery pack (26) about a casing axis. The spring arm (56, 190, 192, 194, 196) maintains the ring (52, 142) in a normally engaged position and upon depressing the push button (54, 172, 174), the battery (26) may be removed from the device (20, 120).

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
65 words
A cap for a battery comprising: a closed cylindrical wall having an external surface and an interior diameter adapted to fit onto a housing of a battery pack; a member extending radially inward from said interior diameter for securing said end to the housing; and a groove in said external surface, said groove adapted for receiving a latch for retaining the cap with the latch.
Claim 2
Dependent Claim
65 words
A cap for a battery comprising: a closed cylindrical wall having an external surface and an interior diameter adapted to fit onto a housing of a battery pack; a member extending radially inward from said interior diameter for securing said end to the housing; and a groove in said external surface, said groove adapted for receiving a latch for retaining the cap with the latch.
Claim 3
Dependent Claim
16 words
The cap according to claim 1, wherein said cylindrical wall includes at least one open end.
Claim 4
Dependent Claim
38 words
The cap according to claim 2, wherein an angled surface is peripherally formed on the external surface adjacent said open end, said angled surface adapted to act as a Cam to spread the latch to retain the cap.
Claim 5
Dependent Claim
19 words
The cap according to claim 2, wherein said cylindrical wall has two ends, one of said ends being closed.
Claim 6
Dependent Claim

The cap according to claim 4, wherein said closed end is dome shaped.
Claim 7
Dependent Claim
17 words
The cap according to claim 1, wherein at least one gripping member is on said external surface.
Claim 8
Dependent Claim
91 words
A battery pack comprising: an elongated casing; a plurality of cells in the casing; a terminal assembly located at one end of the casing and a cap located on the other end of the casing; the cap including a cylindrical wall; a bead is formed on an interior surface of the cylindrical cap wall and is located in a recess in the casing to retain the cap on the casing; and an annular groove in the cylindrical wall adapted for receiving a latch for retaining the pack in a cordless device.
Claim 9
Dependent Claim
91 words
A battery pack comprising: an elongated casing; a plurality of cells in the casing; a terminal assembly located at one end of the casing and a cap located on the other end of the casing; the cap including a cylindrical wall; a bead is formed on an interior surface of the cylindrical cap wall and is located in a recess in the casing to retain the cap on the casing; and an annular groove in the cylindrical wall adapted for receiving a latch for retaining the pack in a cordless device.
Claim 10
Dependent Claim
21 words
The pack of claim 7, wherein: the cap is slidable fitted on the casing; and the casing has an annular recess.
Claim 11
Dependent Claim
73 words
A cap for a battery comprising: a closed cylindrical wall having an external surface and an interior opening, said interior opening adapted to surround a housing of a battery and secure to the housing; and a groove in said external surface, said groove adapted to receive a latch within said groove for retaining the cap with a latch, said groove defining an abutment surface circumferentially surrounding said cylinder wall for abutting the catch.
Claim 12
Dependent Claim
73 words
A cap for a battery comprising: a closed cylindrical wall having an external surface and an interior opening, said interior opening adapted to surround a housing of a battery and secure to the housing; and a groove in said external surface, said groove adapted to receive a latch within said groove for retaining the cap with a latch, said groove defining an abutment surface circumferentially surrounding said cylinder wall for abutting the catch.
