Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
85 words
A battery and battery receptacle arrangement, comprising (a) a battery as a first part of the arrangement, (b) a battery receptacle as a second part of the arrangement, (c) at least one formation provided on one of the parts, (c) a corresponding formation provided on the other part, which corresponding formation is engaged by the said at least one formation when the battery is inserted in the receptacle and moved transversely therewithin, thereby to retain the battery in the receptacle in a readily releasable manner.
Claim 2
Dependent Claim
85 words
A battery and battery receptacle arrangement, comprising (a) a battery as a first part of the arrangement, (b) a battery receptacle as a second part of the arrangement, (c) at least one formation provided on one of the parts, (c) a corresponding formation provided on the other part, which corresponding formation is engaged by the said at least one formation when the battery is inserted in the receptacle and moved transversely therewithin, thereby to retain the battery in the receptacle in a readily releasable manner.
Claim 3
Dependent Claim
26 words
An arrangement according to claim 1, in which the formation provided on one of the parts comprises a projection, and the corresponding formation comprises a hole.
Claim 4
Dependent Claim
16 words
An arrangement according to claim 2, in which the projection is provided on the battery casing.
Claim 5
Dependent Claim
80 words
An arrangement according to claim 2, in which the projection has a transverse portion which is spaced from the said one of the parts, and which extends in a transverse direction which is transverse to the outward direction of projection, the receptacle as a whole permitting movement of the battery therewithin in a transverse direction, to enable the projection to be locked onto the other part at the hole thereof and thereby retain the battery in a readily releasable manner.
Claim 6
Dependent Claim
32 words
An arrangement according to claim 2, which the projection has a simple hook construction so that it can be inserted through the hole and hooked onto a portion which defines the hole.
Claim 7
Dependent Claim
38 words
An arrangement according to claim 2, in which the projection is provided with a slanting surface that urges the projection out of engagement with the hole when the battery is moved in a transverse direction within the receptacle.
Claim 8
Dependent Claim
37 words
An arrangement according to claim 2, which the hole is provided with a slanting surface that urges the projection out of engagement with the hole when the battery is moved in a transverse direction within the receptacle.
Claim 9
Dependent Claim
45 words
An arrangement according to claim 1, in which both the battery and the receptacle have a rectangular shape, and in which the transverse direction of permitted movement of the battery within the receptacle is parallel or substantially parallel to the longer sides of the rectangle.
Claim 10
Dependent Claim
29 words
An arrangement according to claim 2, in which the projection is on the intended underside of the battery casing, and the hole is in the bottom of the receptacle.
Claim 11
Dependent Claim
48 words
An arrangement according to claim 1, in which at least one spring member is attached to one of the parts of the arrangement and presses against the other part of the arrangement, to resist the otherwise permitted movement of the battery within the casing in a transverse direction.
Claim 12
Dependent Claim
96 words
An arrangement according to claim 10, in which the spring member is contained within the battery, to urge a slidable member, also accommodated within the battery, in a slide direction which is transverse to the said transverse direction of movement of the battery within the receptacle, and a sloping member is fixed within the receptacle in such a position that the said slide member in the battery engages the sloping member in the receptacle when the battery is inserted therein, to resist the otherwise permitted movement of the battery within the receptacle in a transverse direction.
Claim 13
Dependent Claim
44 words
An arrangement according to claim 1, in which substantially the whole of the battery fits in the receptacle so that when the battery is inserted in the receptacle an outer surface of the battery casing is substantially flush with a rim of the receptacle
Claim 14
Dependent Claim
27 words
An arrangement according to claim 12, positioned in a prosthesis so that the receptacle is positioned to define a recess in the outer surface of the prosthesis.
