Reinforcing apparatus for a lever handle of a door lock

A lever handle of a door lock, which is reinforced to maintain a horizontal position comprising:

• a driving shaft connected to said lever handle;
• a housing provided around said driving shaft and having a wall transverse to said driving shaft, said wall having an outer side facing said lever handle and an inner side which is opposite to said outer side, said wall further having a tubular wall portion which projects axially from said wall and which defines a hole for passage of said driving shaft, said tubular wall portion having a distal end portion;
• a rotary member mounted on said housing for rotating simultaneously with said driving shaft, said rotary member being received in said hole and surrounded by said tubular wall portion;
• said rotary member having first means projecting radially and outwardly therefrom to bear against said wall so as to prevent an axial and outward releasing movement of said rotary member, said rotary member further having second means which projects radially and outwardly to engage said distal end portion for preventing an axial and inward releasing movement of said rotary member, said first and second means being one piece with said rotary member;
• a coiled spring sleeved around said rotary member and having two ends in the form of legs;
• said rotary member further having means for engaging one of said legs of said coiled spring, said engaging means projecting from and being one piece with said rotary member, said engaging means generating a stress on said coiled spring upon rotation of said rotary member;
• and
• said housing further including a stopping means provided on said wall thereof so as to immobilize the other one of said legs of said coiled spring.
