Patent ID: 7461869

Claim:
An air brake hose coupling member for an air brake hose assembly for one of a rail car and truck trailer, such air brake hose being suspendably supported by a hose support member, said air brake hose coupling member comprising: (a) a generally tubular body with a longitudinal axis and an inner coupling face at a first end that is aligned generally in a plane parallel to the longitudinal axis and extending around an air passage; (b) a neck extending from a second end of said generally tubular body for connection to such air brake hose; (c) a flange formed on said generally tubular body adjacent said neck and having an aperture; (d) an arcuate locking flange projecting outwardly from said first end of said generally tubular body; (e) an annular flange formed on said generally tubular body and projecting outwardly from a top portion thereof, wherein said arcuate locking flange and said annular flange are adapted to engage with an annular flange and an arcuate locking flange, respectively, of another air brake hose coupling member to couple said members together when inner coupling faces of said two coupling members are placed in an abutting relationship substantially along their entire inner coupling faces and rotated with respect to each other into a locked position; and (f) a locking means having a first attachment means for attachment to said aperture of said flange and having a second attachment means for attachment to a distal end of such hose support member, said locking means further having a predetermined portion thereof mounted for reciprocal movement in a direction generally parallel to the longitudinal axis of generally tubular body movable in a first direction for enabling said rotation of said two air brake hose coupling members into said locked position, said predetermined portion movable in a second direction, after said two air brake hose coupling members completed said rotation with respect to each other into said locked position, for preventing a rotational uncoupling of said two air brake hose coupling members, whereby a subsequent movement of said predetermined portion in said first direction enables said rotational uncoupling of said two air brake hose coupling members.
