Locking assembly

A locking assembly comprising:

• a ring member adapted to fit about a cover portion, said ring member having first and second ends, a first flange extending from said first ring member end and a second flange extending from said second ring member end, said first and second flanges extending outwardly from said ring member generally parallel to each other, and
• locking means for locking said first and second flanges together, said locking means comprising a stud member and a housing member adapted to be permanently interengaged, said stud member comprising a shank portion and a collar portion, and said housing member comprising a body portion having a cavity therein adapted to receive said stud member shank portion and lockingly retain said shank portion therein with said first and second flanges locked between said housing member body portion and said stud member collar portion,
• said housing member body portion having a circular groove in the inside wall of said cavity, a snap ring disposed in said circular groove,
• said shank portion having a circumferential groove adapted to receive said snap ring to lock said housing member and said stud member together,
• said locking means having a frangible portion,
• said frangible portion being disposed in said collar member, said collar member having an annular recess therein adjacent a central aperture therethrough, a head portion of said shank portion at one end of said shank portion being disposed in said recess, said head portion having groove means at its juncture with said shank portion, said groove means defining said frangible portion, such that said head portion is adapted to break away at said groove from said shank portion, facilitating the parting of said collar portion from said stud portion, and
• said locking means having recess means therein for receiving a pressure-applying tool for breaking of said frangible portion

A locking assembly comprising a ring member having first and second ends, a first flange extending from said first end and a second flange extending from said second end, said first and second flanges extending outwardly from said ring member and generally parallel to each other, locking means for locking said first and second flanges together, said locking means comprising a stud member and a housing member adapted to be permanently interengaged, said housing member comprising a flange portion, a tubular body portion extending from said housing member flange portion, said body portion having an open-ended cavity therein and a circular groove internally thereof, and a snap ring member disposed in said circular groove, said stud member comprising a shank portion and a collar portion fixed to a first end of said shank portion, said shank portion having circumferential groove means therein, said housing member body portion being adapted to receive said stud member shank portion, said shank portion circumferential groove means being adapted to receive in part said housing member snap ring to lock said housing member and said stud member together, tool means adapted to release said flanges from each other by deformation of said locking means, said locking means including a frangible portion and said deformation of said locking means comprising breaking of said frangible portion, said locking means being adapted to receive said tool means, said tool means comprising first and second arms extending from a handle portion, and a plunger member disposed in one of said arms and axially movable toward the other of said arms, a locking means recess being adapted to receive an end of said plunger member of said tool means while said locking means is disposed between said tool means other arm and said plunger member, movement of said plunger member toward said other arm being operative to break said frangible portion of said locking means.

A locking assembly adapted for locking first and second members together, said assembly comprising a housing member and a stud member, said housing member having a body portion having a cavity therein, said housing member body portion having a circular groove in the inside wall of said cavity, a snap ring disposed in said groove, said stud member comprising a shank portion and a collar portion, said shank portion having a circumferential groove adapted to receive said snap ring, said housing member body portion cavity being adapted to receive said stud member shank portion with said snap ring permanently locking said stud member shank portion in said housing member body portion cavity with said first and second members disposed between said housing member body portion and said stud member collar portion, said stud member having a frangible portion, said frangible portion being disposed in said collar portion, such that upon breaking of said frangible portion of said collar portion, said collar portion is adapted to part from a remainder of said stud member, said stud member comprising a single unitary member having as integral portions thereof said shank portion and said collar portion, said collar portion being disposed at one end of said shank portion and extending radially outwardly from said shank portion, said frangible portion comprising an annular recess in said collar portion adjacent said shank portion, said recess being formed in part by a wall of said shank portion, whereby said collar portion of said stud member is adapted to be broken away from said remainder of said stud member to facilitate removal of said assembly from said first and second members.
