Rotatable hook mount for utility light

A rotatable hook mount apparatus for suspending a utility light therefrom comprising:

• a first locking member, said first locking member having a disk portion and a projection portion, said projection portion adapted to be attached to a utility light, said disk portion having an upper planar face, a lower planar face, and a first bore formed therethrough between said faces, said upper face of said disk portion having a first means for preventing rotation formed thereon;
• a disk-shaped second locking member having an upper planar face, a lower planar face, and a second bore formed therethrough between said upper and lower faces of said second locking member, said lower face of said second locking member having a second means for preventing rotation formed thereon, said second bore having at least one groove formed in a wall thereof adjacent to said upper face of said second locking member;
• a hook member having a shaft portion and a hook portion, said shaft portion having at least one projection extending therefrom, said shaft portion of said hook member being received in said second bore of said second locking member with said at least one projection engaging said at least one groove, said shaft portion being rotatably received in said first bore of said first locking member;
• and
• a spring member mounted on said shaft portion and biasing said lower face of said second locking member toward said upper face of said first locking member to releasably engage said first and second means for preventing rotation.

A rotatable hook mount apparatus for suspending a utility light having a light guard comprising:

• a lower locking member having a disk portion and a projection portion, said projection portion adapted to be attached to a light guard and having a lip formed thereon for engaging the light guard, said disk portion having an upper face, a lower face, and a first bore formed therethrough between said faces, said upper face of said disk portion having a first set of teeth formed thereon;
• a disk-shaped upper locking member having an upper face, a lower face, and a second bore formed therethrough between said upper locking member faces, said lower face of said upper locking member having a second set of teeth formed thereon;
• a hook member having a shaft portion and a hook portion, said shaft portion having a pair of projections fixedly received in an associated pair of grooves in a wall of said second bore of said upper locking member and being rotatably received in said first bore of said lower locking member, said shaft portion extending beyond said lower planar face of said lower locking member;
• a spring received on said shaft portion of said hook member and extending into a counterbore formed in said lower face of said lower locking member;
• and
• a retaining means attached to said shaft portion for retaining said spring member on said shaft portion, said spring member biasing said upper locking member against said lower locking member whereby said first and second sets of teeth engage and cooperate to prevent relative rotation between said lower and upper locking members and whereupon movement of said hook member and said upper locking member away from said upper surface of said lower locking member disengages said first and second sets of teeth to permit rotation of said hook member relative to said lower locking member.
• a hook member having a shaft portion and a hook portion, said shaft portion having a pair of projections fixedly received in an associated pair of grooves in a wall of said second bore of said upper locking member and being rotatably received in said first bore of said lower locking member, said shaft portion extending beyond said lower planar face of said lower locking member;
• a spring received on said shaft portion of said hook member and extending into a counterbore formed in said lower face of said lower locking member;
• and
• a retaining means attached to said shaft portion for retaining said spring member on said shaft portion, said spring member biasing said upper locking member against said lower locking member whereby said first and second sets of teeth engage and cooperate to prevent relative rotation between said lower and upper locking members and whereupon movement of said hook member and said upper looking member away from said upper surface of said lower locking member disengages said first and second sets of teeth to permit rotation of said hook member relative to said lower locking member.

A rotatable hook mount apparatus for suspending a utility light having a light guard comprising:

• a lower locking member having a disk portion and a projection portion, said projection portion adapted to be attached to a light guard and having a lip extending between said disk portion and said projection portion for engaging the light guard, said disk portion having an upper face, a lower face, and a first bore formed therethrough between, said faces, said upper face of said disk portion having a first set of teeth formed thereon, said lip extending in a plane generally parallel to an axis of said first bore;
• a disk-shaped upper locking member having an upper face, a lower face, and a second bore formed therethrough between said upper locking member faces, said lower face of said upper locking member having a second set of teeth formed thereon;
• a hook member having a shaft portion and a book portion, said shaft portion being fixedly received in said second bore of said upper locking member for rotation therewith and being rotatably received in said first bore of said lower locking member, said shaft portion extending beyond said lower planar face of said lower locking member;
• a spring received or said shaft portion or said hook member adjacent said lower face of said lower locking member;
• and
• a retaining means attached to said shaft portion for retaining said spring member on said shaft portion, said spring member biasing said upper locking member against said lower locking member whereby said first and second sets of teeth engage and cooperate to prevent relative rotation between said lower and upper locking members and whereupon movement of said hook member and said upper locking member away from said upper surface of said lower locking member disengages said first and second sets of teeth to permit rotation of said hook member with said upper locking member relative to said lower locking member.

• a first locking member, said first locking member having a disk portion and a projection portion, said projection portion adapted to be attached to a light guard, said disk portion having an upper face, a lower face, and a first bore formed therethrough between said faces, said upper face of said disk portion having a first means for preventing rotation formed thereon;
• a disk-shaped second locking member having an upper face, a lower face, and a second bore formed therethrough between said second locking member faces, said lower fare of said second locking member having a second means for preventing rotation formed thereon, and at least one axially extending groove formed in a wall of said second bore and open at said upper face of said second locking member;
• a hook member having a shaft portion and a hook portion, said shaft portion being fixedly received in said second bore of said second locking member and being rotatably received in said first bore of said first locking member, said shaft portion extending beyond said lower planar face of said first locking member, said shaft portion including at least one projection extending therefrom and received in said at least one groove formed in said second locking member;
• a spring member received on said shaft portion of said hook member below said lower face of said first locking member;
• and
• a retaining means attached to said shaft portion for retaining said spring member on said shaft portion, said spring member biasing said second locking member against said first locking member whereby said first and second means for preventing rotation engage and cooperate to prevent relative rotation between said first and second locking members and whereupon movement of said hook member and said second locking member away from said upper surface of said first locking member disengages said first and second means for preventing rotation to permit rotation of said hook member with said second locking member relative to said first locking member.
