Abstract
Abstract A battery-retaining device comprising a battery holder pivotable about a pivot arranged in a battery housing from an operating position in the housing to a battery-replacement position outside the housing, one or more batteries being clamped between electrical contacts in the operating position but not being subjected to such clamping in the battery-replacement position. During the pivoting of the holder from the battery-replacement position towards the operating position, the contact force exerted on such one or more batteries by the electrical contacts is gradually increased.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
196 words
A device for retaining one or more batteries in position, which comprises a battery housing having a wall portion, a first pivot provided in said housing, a holder for said one or more batteries, said holder being pivotable about said first pivot between an operating position within said housing to a battery-replacement position outside said housing, a first electrical contact and a second electrical contact for clamping said one or more batteries therebetween in said operating position, said one or more batteries thereby being subjected to a substantially centrically directed end contact force in said operating position, said one or more batteries not being subjected to clamping between said electrical contacts in said replacement position, a second pivot provided on said holder, and a panel associated with said holder and being pivotable about said second pivot with respect to said holder, one side of said panel being in pressure contact, during movement of said holder to its operating position, with said housing wall portion, said first electrical contact being provided on the other side of said panel, said first electrical contact thereby creating during said holder movement said end contact force at a gradually increasing strength.
Claim 2
Independent Claim
196 words
A device for retaining one or more batteries in position, which comprises a battery housing having a wall portion, a first pivot provided in said housing, a holder for said one or more batteries, said holder being pivotable about said first pivot between an operating position within said housing to a battery-replacement position outside said housing, a first electrical contact and a second electrical contact for clamping said one or more batteries therebetween in said operating position, said one or more batteries thereby being subjected to a substantially centrically directed end contact force in said operating position, said one or more batteries not being subjected to clamping between said electrical contacts in said replacement position, a second pivot provided on said holder, and a panel associated with said holder and being pivotable about said second pivot with respect to said holder, one side of said panel being in pressure contact, during movement of said holder to its operating position, with said housing wall portion, said first electrical contact being provided on the other side of said panel, said first electrical contact thereby creating during said holder movement said end contact force at a gradually increasing strength.
Claim 3
Dependent Claim
27 words
A device according to claim 1, in which the panel is provided with a guide in pressure contact with said housing wall portion during said holder movement.
Claim 4
Dependent Claim
33 words
A device according to claim 1, in which the first pivot and the second pivot are parallel to each other and are perpendicular to the longitudinal direction of said one or more batteries.
Claim 5
Dependent Claim
73 words
A device according to claim 3, in which the holder includes a bottom extending perpendicularly to the first pivot and the second pivot, and two parallel longitudinal walls extending perpendicularly from the bottom, said pivotable panel forming an end wall for the holder, the opposite end of the holder being open, said second electrical contact being arranged in said housing for end contact with said one or more batteries in said operating position.
Claim 6
Dependent Claim
37 words
A device according to claim 4, in which the bottom of the holder is formed with two parallel longitudinal compartments for accommodating two rows of batteries electrically connected in series by means of said first electrical contact.
Claim 7
Dependent Claim
35 words
A device according to claim 1, in which the first electrical contact comprises a helical spring in the form of a truncated cone having a longitudinal axis extending perpendicularly to the plane of the panel.
