Abstract
Abstract A magazine for recording tape cassettes for use in vehicles has a plurality of chambers, each for the reception of a cassette and each having an opening corresponding to the cassette's smallest cross-section. The chambers have cantilevered spring leaves arranged at their top walls which leaves carry locking members including plates with cam-like edges projecting downwardly so as to engage the hub openings of the cassette reels to lock the reels and retain the cassettes in the chambers and to force them against their bottom support. The chambers further have resilient guide straps disposed at one of their sides so as to project into the chambers and engage and force the cassettes therein into firm engagement with the opposite chamber side walls, all chambers being formed by drawer-like building elements stacked on top of one another and compressed within the magazine housing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
269 words
A magazine for recording tape cassettes especially for use in vehicles, comprising a housing having a number of chambers, each for the reception of one cassette, each said chamber having an opening of a cross-section corresponding to the smaller cross-section of a tape cassette and adapted to receive such cassette lengthwise; said chambers being arranged horizontally and formed by drawer-like building elements stacked on top of one another and compressed within said cassette housing, one being disposed on top of each chamber, each of said building elements having at least one spring leaf cantilevered from each building element so as to extend essentially in the direction of movement of a cassette into, and out of, said chamber, said spring leaf having a free end movable relative to said chamber; a locking member supported at the free end of each spring leaf so as to project downwardly into said chamber for engagement with the hub opening of at least one of a tape cassette's reel hub openings, said locking member including a cam-like rib projection oriented also in the direction of movement of a cassette into, and out of, said chamber, said cam-like rib having cam-like edges adapted to cause the locking member to resiliently back up when a cassette portion is moved past them, each of said building elements having downwardly projecting side walls at opposite sides of said chambers with resilient guide straps disposed at one side thereof and projecting into said chamber and engaging herein any cassette inserted into said chamber so as to force said cassette into engagement also with the opposite wall of said chamber.

A magazine for recording tape cassettes especially for use in vehicles, comprising a housing having a number of chambers, each for the reception of one cassette, each said chamber having an opening of a cross-section corresponding to the smaller cross-section of a tape cassette and adapted to receive such cassette lengthwise; said chambers being arranged horizontally and formed by drawer-like building elements stacked on top of one another and compressed within said cassette housing, one being disposed on top of each chamber, each of said building elements having at least one spring leaf cantilevered from each building element so as to extend essentially in the direction of movement of a cassette into, and out of, said chamber, said spring leaf having a free end movable relative to said chamber; a locking member supported at the free end of each spring leaf so as to project downwardly into said chamber for engagement with the hub opening of at least one of a tape cassette's reel hub openings, said locking member including a cam-like rib projection oriented also in the direction of movement of a cassette into, and out of, said chamber, said cam-like rib having cam-like edges adapted to cause the locking member to resiliently back up when a cassette portion is moved past them, each of said building elements having downwardly projecting side walls at opposite sides of said chambers with resilient guide straps disposed at one side thereof and projecting into said chamber and engaging herein any cassette inserted into said chamber so as to force said cassette into engagement also with the opposite wall of said chamber.
Claim 3
Dependent Claim
16 words
A magazine according to claim 1, wherein said drawer-like building elements are formed from plastic material.
Claim 4
Dependent Claim
71 words
A magazine according to claim 1, wherein each spring leaf is cantilevered at one end and has one locking member disposed at its free end so as to be adapted to engage one of the reels of said cassette and wherein a cantilevered spring tongue is formed from said spring leaf and has another locking member arranged at its free end and adapted to engage the other reel of said cassette.
Claim 5
Dependent Claim
71 words
A magazine according to claim 1, wherein two spring leaves are arranged side-by-side and cantilevered at opposite ends, the free end of said cantilevered spring leaves carrying locking members arranged as to project in the reel hub openings of a cassette inserted into a chamber, one of said spring leaves being cantilevered at the front end of said building element and the other at the rear end of said building element.
Claim 6
Dependent Claim
50 words
A magazine according to claim 1, wherein the height of said cam-like rib is slightly more than half the thickness of a cassette and the cam edges are arranged at an angle of about 50° relative to the plane of the spring leaf on which the locking member is disposed.
Claim 7
Dependent Claim
36 words
A magazine according to claim 1, wherein said locking members have two parallel cam plates spaced from one another such that the distance between their outside surfaces is slightly less than the reel hub opening diameter.
Claim 8
Dependent Claim
55 words
A magazine according to claim 6, wherein at least one of said cam ribs has a side rib formed thereon so as to extend normal with respect to the cam rib and the spring leaf, said side rib projecting from the cam rib so as to be snugly received in the respective reel hub opening.
Claim 9
Dependent Claim
57 words
A magazine according to claim 1, wherein slide strips are longitudinally arranged in said chambers on the chamber floors and extend parallel to the chamber's side walls, said strips having a height slightly larger than the projection of a tape cassette's window area such that a cassette is supported in said chamber solely on said slide strips.
Claim 10
Dependent Claim
50 words
A magazine according to claim 8, wherein, in a tape cassette insert-direction the slide strip arranged at the right-hand chamber side is sufficiently spaced from the right-hand chamber side wall to accummodate the tape cassette's thickened window area between the chambers right-hand side wall and said right side slide strip.
Claim 11
Dependent Claim
