Abstract
Abstract A container for magnetic tape cassettes has a housing having a plurality of receiving compartments for magnetic tape cassettes, a plurality of base plates separating the compartments from one another, a lockable slider member ejectable under a spring action to a position in which a magnetic tape cassette arranged on the base plate can be removed, resilient locks provided on the slider member and formed as pivotable rocker arms adapted to engage two reel hubs of a magnetic tape cassette, projections arranged on the base plate, and elevations. The rocker arms have laterally mounted pegs which, when the slider member is ejected, disengage the rocker arms from the reel hub by running beneath the projections, and when the slider member is inserted, engage the rocker arms in the reel hub by running on the elevations.

Claim 1
Independent Claim
243 words
A container for magnetic tape cassettes, comprising a housing having a plurality of receiving compartments for magnetic tape cassettes; a plurality of base plates separating said compartments from one another; a lockable slider member ejectable under a spring action to a position in which a magnetic tape cassette arranged on said base plate can be removed; resilient locking means provided on said slider member and formed as pivotable rocker arms adapted to engage two reel hubs of a magnetic tape cassette; projections arranged on said base plate; elevations, said rocker arms having laterally mounted pegs which, when the slider member is ejected, disengage said rocker arms from the reel hub by running beneath said projections, and when said slider member is inserted, engage said rocker arms in the reel hub by running on said elevations, wherein said locking means being arranged in an insertion direction of said slider member so that a longitudinal insertion of the magnetic tape cassette is possible, each of said locking means being formed by two of said rocker arms arranged side-by-side and pivotable independently of one another, said base plate being provided with projections associated with each rocking arm for its disengagement; and a sliding element mounted on said base plate and displaceable by a magnetic tape cassette transversely to the insertion direction, displacement of said sliding element causing a respective elevation to be arranged for engagement of one of said two rocker arms of said locking means.

A container for magnetic tape cassettes, comprising a housing having a plurality of receiving compartments for magnetic tape cassettes; a plurality of base plates separating said compartments from one another; a lockable slider member ejectable under a spring action to a position in which a magnetic tape cassette arranged on said base plate can be removed; resilient locking means provided on said slider member and formed as pivotable rocker arms adapted to engage two reel hubs of a magnetic tape cassette; projections arranged on said base plate; elevations, said rocker arms having laterally mounted pegs which, when the slider member is ejected, disengage said rocker arms from the reel hub by running beneath said projections, and when said slider member is inserted, engage said rocker arms in the reel hub by running on said elevations, wherein said locking means being arranged in an insertion direction of said slider member so that a longitudinal insertion of the magnetic tape cassette is possible, each of said locking means being formed by two of said rocker arms arranged side-by-side and pivotable independently of one another, said base plate being provided with projections associated with each rocking arm for its disengagement; and a sliding element mounted on said base plate and displaceable by a magnetic tape cassette transversely to the insertion direction, displacement of said sliding element causing a respective elevation to be arranged for engagement of one of said two rocker arms of said locking means.
Claim 3
Dependent Claim
49 words
A container as defined in claim 1; and further comprising wedge-shaped control members arranged on two longitudinal sides of said slider element and penetrating said base plate so as to project above an upper side of said base plate for displacement of said sliding element by a cassette enlargement.
Claim 4
Dependent Claim
20 words
A container as defined in claim 1; and further comprising means for attaching said rocker arm to said slider element.
Claim 5
Dependent Claim
24 words
A container as defined in claim 3, wherein said attaching means includes an integral hinge which attaches said rocker arm to said slider element.
Claim 6
Dependent Claim
17 words
A container as defined in claim 1, wherein said elevations and said projections are provided with ramps.
Claim 7
Dependent Claim
161 words
A container for magnetic tape cassettes, comprising a housing having a plurality of receiving compartments for magnetic tape cassettes; a plurality of base plates separating said compartments from one another; a lockable slider member ejectable under a spring action to a position in which a magnetic tape cassette arranged on said base plate can be removed; resilient locking means provided on said slider member and formed as pivotable rocker arms adapted to engage two reel hubs of a magnetic tape cassette; projections arranged on said base plate; elevations, said rocker arms having laterally mounted pegs which, when the slider member is ejected, disengage said rocker arms from the reel hub by running beneath said projections, and when said slider member is inserted, engage said rocker arms in the reel hub by running on said elevations; and a pivotable closure flap mounted on said slider member and immobilizable in an extended and folded-up position; and means for immobilizing said pivotable closure flap.
Claim 8
Dependent Claim
