Definitions

  • the invention relates to a lock for a closure panel, or cover, of an apparatus such as a cassette player and to an apparatus comprising such a lock.
  • Cassette players being devices manufactured in large series, it is desirable that the various elements which constitute them are simple and inexpensive while being reliable, satisfactory operation and easy handling and replacement.
  • the invention overcomes these drawbacks.
  • the device according to the invention comprises a lock of the type described in US Pat. No. 2,803,476, that is to say which is provided with a lug which can be fixed to the body of the device and with a flexible clip. of this tab to the body of the lock, the actuation of this lock being obtained by bending the fastener.
  • This device is characterized in that the latch tab being fixed by snap-fastening to the body of the device and the insertion of the tab in its housing also being obtained by bending the fastener, said tab ends in a redent cooperating with a shoulder of its housing and in that, to allow separation of the lock from the body of the device, in this housing opens a hole into which a tool can be introduced to push the tab blocked by the stop.
  • a device thus constituted satisfies all of the conditions listed above.
  • the lock body, the tab and the flexible fastener are in one piece, in particular made of plastic.
  • the body of the lock has an actuation and veroulliage head having the shape of a simple rectangular plate, and a frame perpendicular to this head, the tab being flexibly attached to the base of this frame and being substantially parallel to the plane of said frame.
  • the tab can itself be flexible.
  • the latch 1 is intended to lock in the closed position the cover 2 of a cassette player-recorder which, as is well known, has a housing (not shown) for a cassette and thus forms cassette loader-unloader for the apparatus.
  • the latch 1 is released from the cover 2 (FIG. 2), this cover 2 is automatically returned to its open position by springs, also not shown.
  • the lock 1 is in one piece, that is to say in one piece, and made of plastic.
  • This head 6 comprises a rigid body having a U-shaped frame 3 (FIG. 3) with an elongated horizontal base 4 and two vertical uprights 9 and 10 attached to the head 6 along their upper edge 5.
  • This head 6 is a rectangular plate whose plane is perpendicular to the plane of the frame 3, and whose thickness is at least equal to the thickness of the frame.
  • the length, parallel to the horizontal base 4, of the head 6 is substantially the same as that of the frame 3, its short sides 7 and 8 being in line with the small vertical sides, respectively 9a and 10a, of the frame 3.
  • the edge 5 common to the uprights 9 and 10 and to the head 6 is closer to the front edge 11 of the head - that is to say of the edge facing the cover 2 - than to the rear edge 12.
  • a large fraction of the frame 3 is placed in a housing 13 presented by the device in the vicinity of the free edge 14 of the cover 2.
  • This housing 13 has a shoulder 15 turned downwards forming a stop for a step 16 at the end of a lug 17 parallel to the frame 3, connecting to the lower edge 4a of the base 4 of this frame by a flexible tongue 18 in the shape of an arc of a circle, the width of the tab 17 is much less than the length of the side 4.
  • This tab 17 is in the middle zone of the side 4 (FIG. 3). In the example, it is flexible like the fastener 18.
  • the tab 17 and its fastener 18 allow, on the one hand, the actuation of the lock and, on the other hand, the snap fastening of the lock to the device.
  • the lug 17 is brought closer to this frame 3, then, when the step 16 is lowered below the shoulder 15, the lug 17 returns by itself, by the elasticity of the plastic, in position parallel to the frame 3 which cannot then leave the housing 13 thanks to the stop of the upper edge of the redent 16 against the shoulder 15.
  • a hole 19 is provided which opens out at the lower part of the housing 13 on the side of the lug 17 so as to allow the introduction of a tool , such as a screwdriver, to push the tab 17 towards the frame 3 and thus release the redent 16 from the shoulder 15.
  • a tool such as a screwdriver
  • the cover 2 has on its free edge 14 a shoulder 21 on which the front end of the head 6 rests.
  • the head 6 is pressed, that is to say a vertical force F directed downwards at any point in the zone 22 of this head 6 behind the frame 3.
  • the body of the lock pivots about an axis which corresponds to the lower edge 4a of the base of the frame 3, by virtue of the bending of the tongue 18 and possibly of the lug 17.
  • the redent 16 is pressed against the rear wall 29 of the housing 13 and the tongue 18 is supported against the bottom 25 of the same housing.
  • the front part of the head 6 is then entirely released from the cover 2.
  • the head 6 has a chamfer 23 turned upwards allowing the lock to tilt backwards, and therefore to disappear, when the cover 2 is brought from the open position to the closed position.
