Abstract
Abstract An electric storage battery arrangement includes a frame which is to be mounted in the prosthetic device, and a storage battery which is insertable into the frame. A snap-holding arrangement holds the storage battery in the frame and includes a lever pivotable in the frame between a releasing and a holding position, being biased toward the releasing position and having one arm that holds the storage battery in the frame. Electric contacts are mounted on the lever, such contacts being arranged in the electric circuit of the drive of the prosthetic device and being in an electric contact with the terminals of the storage battery when the latter is fully inserted in the frame. The lever has a pair of cylindrical projections received in a depression of the frame and held therein against displacement other than pivoting by an arresting member connected to the frame. The storage battery has a centering recess intermediate the terminals, and another recess at the end spaced from the terminals, and a centering projection of the lever, and another projection of the frame, are received therein when the battery is at least partly inserted into the frame. A pressing member is urged into contact with the centering projection when received in the centering recess.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
101 words
An electric storage battery arrangement for use in a prosthetic device of the type having an electric drive and an electric circuit for the same, comprising, in combination, a mounting frame adapted to be mounted on the prosthetic device; a storage battery interchangeably insertable into said mounting frame and having a pair of electric terminals configurated with respective slots; and a pair of electric contacts arranged in the electric circuit and constructed as contact blades receivable in said respective slots for establishing electric contact with said electric terminals of said storage battery when the latter is inserted into said mounting frame.
Claim 2
Dependent Claim
101 words
An electric storage battery arrangement for use in a prosthetic device of the type having an electric drive and an electric circuit for the same, comprising, in combination, a mounting frame adapted to be mounted on the prosthetic device; a storage battery interchangeably insertable into said mounting frame and having a pair of electric terminals configurated with respective slots; and a pair of electric contacts arranged in the electric circuit and constructed as contact blades receivable in said respective slots for establishing electric contact with said electric terminals of said storage battery when the latter is inserted into said mounting frame.
Claim 3
Dependent Claim
26 words
A combination as defined in claim 1, wherein said electric contacts are mounted on said mounting frame upon mounting of the latter on the prosthetic device.
Claim 4
Dependent Claim
26 words
A combination as defined in claim 1; and further comprising a snap-action holding arrangement for holding said storage battery in said mounting frame upon insertion thereinto.
Claim 5
Dependent Claim
67 words
A combination as defined in claim 3, wherein said holding arrangement includes a lever mounted on said mounting frame for pivoting between a releasing position for insertion and withdrawal of said storage battery, and a holding position for holding said storage battery in said mounting frame upon insertion, said lever including one arm which abuts against said inserted storage battery in said holding position of said lever.
Claim 6
Dependent Claim
36 words
A combination as defined in claim 4, wherein said lever also has another arm; and further comprising biasing means extending between said mounting frame and said lever and urging the latter toward said releasing position thereof.
Claim 7
Dependent Claim
46 words
A combination as defined in claim 4, wherein said mounting frame has a depression; and wherein said lever has a pair of cylindrical projections laterally thereof, said projections being receivable in said depression and mounting said lever for pivoting between said releasing and holding positions thereof.
Claim 8
Dependent Claim
34 words
A combination as defined in claim 6, and further comprising an arresting insert mounted on said mounting frame and operative for arresting said cylindrical projections in said depression against all movement but said pivoting.
Claim 9
Dependent Claim
29 words
A combination as defined in claim 7; and further comprising biasing means arranged between said arresting insert and said lever and urging the latter toward said releasing position thereof.
Claim 10
Dependent Claim
32 words
A combination as defined in claim 8, wherein said arresting insert includes a groove; and wherein said biasing means includes an annular spring partly accommodated in said groove of said arresting insert.
Claim 11
Dependent Claim
65 words
A combination as defined in claim 4, wherein said mounting frame is elongated and said lever is mounted at one longitudinal end thereof; and further comprising a connecting recess on said storage battery and a connecting projection on the other longitudinal end of said mounting frame and received in said connecting recess when said storage battery is at least partly inserted into said mounting frame.
Claim 12
Dependent Claim
27 words
A combination as defined in claim 1, wherein said storage battery has a length and a width; and wherein said length is approximately three times said width.
Claim 13
