Low profile deadbolt assembly

A deadbolt assembly, comprising:

• a bolt housing having a longitudinal sleeve defining a first axis;
• a bolt having a distal end and a proximal end, said bolt being located in said longitudinal sleeve and configure to move between a fully retracted position and a fully extended position;
• a first actuator assembly having a body, a lock cylinder and a drive, said lock cylinder being mounted to said body, and said drive extending from said lock cylinder, said drive being rotatable around a second axis with respect to said lock cylinder;
• a slide member having a first end and a second end portion opposite said first end, said first end being attached to said proximal end of said bolt and said second end portion having a first connector;
• a rotatable crank having a pivot member, a second connector and an arm extending between said pivot member and said second connector, said pivot member being engaged with said drive of said first actuator assembly to facilitate rotation of said crank with a corresponding rotation of said drive around said second axis, and said second connector of said crank being operationally engaged with said first connector of said slide member;
• and
• a stationary guide rail attached to said bolt housing, said guide rail defining a third axis that is substantially parallel to said first axis, and said slide member being configured for longitudinal movement along said third axis when said bolt is moved between said fully retracted position and said fully extended position, said stationary guide rail having a notch, and said lock cylinder having an upper surface positioned within said notch of said stationary guide rail, with a clearance between said upper surface of said lock cylinder and a lower surface defined by said notch to accommodate an extent of said lock cylinder.

A deadbolt assembly, comprising:

• a bolt housing having a longitudinal sleeve defining a first axis;
• a bolt having a distal end and a proximal end, said bolt being located in said longitudinal sleeve and configure to move between a fully retracted position and a fully extended position;
• an elongate member having a first end, a second end portion opposite said first end, a first outer side surface and a second outer side surface spaced apart from said first outer side surface, said first end being attached to said proximal end of said bolt, and said second end portion having a first connector;
• a guide rail attached to said bolt housing, said elongate member being configured for longitudinal movement relative to said guide rail, said guide rail having a notch;
• a first actuator assembly having a body, a lock cylinder and a tailpiece, said lock cylinder being mounted to said body, and said tailpiece extending from said lock cylinder, said tailpiece being rotatable with respect to said lock cylinder around a second axis, said lock cylinder having an outer surface that is positioned within said notch of said guide rail;
• and said notch providing a clearance between a surface of said lock cylinder and a surface of said guide rail to accommodate an extent of said lock cylinder
• a second actuator assembly including a mounting plate, a turnpiece and a crank, said crank having a pivot member, a second connector and an arm extending between said pivot member and said second connector, said second connector of said crank being operationally engaged with said first connector of said elongate member,
• said turnpiece and said crank being rotatably mounted to said mounting plate, said pivot member of said crank being connected to said turnpiece and to said tailpiece to facilitate rotation of said crank with a corresponding rotation of said turnpiece and said tailpiece around said second axis, and wherein said arm of said crank is interposed between said second outer side surface of said elongate member and said mounting plate of said second actuator assembly.

A method of assembling a deadbolt assembly including a bolt housing having a longitudinal sleeve defining a first axis, a bolt having a distal end and a proximal end, said bolt being located in said longitudinal sleeve and configured to move between a fully retracted position and a fully extended position along said first axis;

• an elongate member having a first end and a second end portion opposite said first end, said elongate member having a first outer side surface and a second outer side surface, said second outer side surface being spaced apart from said first outer side surface;
• and a guide rail attached to said bolt housing, said elongate member being configured for longitudinal movement relative to said guide rail, said guide rail having a notch, said method comprising:
• providing a rotatable crank having a pivot member, a second connector and an arm extending between said pivot member and said second connector;
• operationally engaging said second connector of said crank with said first connector of said elongate member;
• providing a first actuator assembly having a body, a lock cylinder and a tailpiece, said lock cylinder being mounted to said body, and said tailpiece extending from said lock cylinder, said tailpiece being rotatable around a second axis with respect to said lock cylinder;
• engaging said tailpiece with said pivot member of said crank to facilitate rotation of said crank with a corresponding rotation of said tailpiece around said second axis;
• and
• positioning at least a portion of said lock cylinder to extend past a vertical plane of said first outer side surface of said elongate member, with an outer surface of said lock cylinder being positioned within said notch of said guide rail.
