Abstract
A security device for mounting in the alignment or positioning channel of video cassette which prevents utilization of the cassette in a VCR. The security device comprises a locking member having tabs which extend into openings of the alignment channel to retain the member therein after insertion into the channel. The locking member is removed by a key which is inserted into the bore of the locking member and has barbs at its lower end which engage the tabs of the locking member and retract them from within the openings to permit the locking member to be withdrawn from the cassette channel. The locking member also may secure the cassette within a container by passing through a hole in the wall of the container and then into the cassette channel aligned therewith.
Claims19
A security device for a cassette of the type having a channel extending at least partially therethrough and having an opening in a sidewall of said channel, said device including:
- a locking member, said locking member capable of engaging said alignment channel, said locking member having at least one tab formed thereon biased in a radially outward direction and being capable of extending into said channel sidewall opening and securing said locking member in said cassette channel, said locking member further having an outwardly extending annular flange located at an upper portion of said member, and a V-shaped guide notch formed in said upper portion and extending downwardly from said flange.
A security device for a cassette of the type having a channel extending at least partially therethrough and having an opening in a sidewall of said channel, said device including:
- a locking member, said locking member capable of engaging said alignment channel, said locking member having at least one tab formed thereon biased in a radially outward direction;
- said tab being capable of extending into said channel sidewall opening and securing said locking member in said cassette channel;
- a key slidably engaging said locking member, said key having a main shaft and a lower shaft with said lower shaft having a smaller diameter than said main shaft and having at least one barb thereon with an inclined surface;
- and said key being formed with at least one guide projection, said guide projection slidably engaged in a guide notch formed in an upper wall portion of the locking member whereby said one barb is rotated upon insertion of said key into said locking member.
A security device adapted to be mounted in an alignment channel of a video cassette to prevent said cassette from being operative in a VCR, said device including:
- (a) a generally cylindrical-shaped locking member insertable into the alignment channel, said locking member having an axially extending bore and a pair of outwardly biased tabs engageable in openings formed in the cassette adjacent to and communicating with the alignment channel;
- and
- (b) a key insertable into the bore of the locking member, said key having a shaft formed with a cylindrical seection complementary to the bore of the locking member and a pair of barbs formed thereon engageable with the tabs of the locking member to retract said tabs from within in the channel openings and to extract the locking member from within said channel.
A security device adapted to be mounted in an alignment channel of a video cassette to prevent said cassette from being operative in a VCR, said device including:
- (a) a generally cylindrical-shaped locking member insertable into the alignment channel, said locking member having an axially extending bore, an inner notch means adjacent the bore, and a pair of outwardly biased tabs engageable in openings formed in the cassette adjacent to and communicating with the alignment channel;
- and
- (b) a key insertable into the bore of the locking member, said key having a pair of barbs formed thereon engageable with the tabs of the locking member to retract said tabs from within in the channel openings and to extract the locking member from within said channel;
- said key being formed with radially outwardly extending projection means engageable with the inner notch means of the locking member as the key is inserted axially into the bore of said locking member causing rotation of said key.
A device for securing a cassette in a storage container, said cassette being of the type having a channel extending at least partially therethrough and having an opening in a sidewall of said channel, said device including:
- (a) a locking member extending through an opening in a wall of the storage container aligned with the cassette channel, said locking member having at least one tab formed thereon extending into said channel sidewall opening and securing said locking member in said cassette channel, and an outwardly extending flange located on a portion of said locking member and engageable with said container wall to secure said locking member to the container when the tab extends into the channel sidewall opening.
