权利要求
1. A combination door handle and latch device, comprising: a. a latch portion comprising: a stem adapted to be received through a hole in a door to be latched; an arm connected to one end of said stem, said arm projecting generally transversely outwardly of said stem; and striker engaging means connected to the other end of said stem; b. a handle portion comprising: a resilient means retaining pocket formed therein and one side of said handle portion; a latch stem receiving aperture formed therein and open to said pocket and cooperating therewith to form a resilient means abutment shoulder; a latch arm clearance notch formed in a wall of said stem receiving aperture and open to said pocket; a latch arm engagement cavity formed in a wall of said stem receiving aperture; and an arm abutment shoulder separaTing said cavity from said pocket; and, c. resilient means disposed in said pocket between the door and said resilient means abutment shoulder to urge said handle portion generally away from said stem portion and cause said stem arm to move into said cavity and force said stem abutment shoulder against said stem arm.
2. The combination door handle and latch as defined in claim 1, wherein said a resilient means abutment shoulder is adjacent the opening of said stem receiving aperture to said pocket.
3. The combination door handle and latch as defined in claim 1, wherein said arm clearance notch is circumferentially displaced around the longitudinal axis of said stem receiving aperture from said arm retaining cavity.
4. The combination door handle and latch as defined in claim 3, wherein said circumferential displacement is approximately 90*.
5. The combination door handle and latch as defined in claim 1, wherein: said latch stem receiving aperture is open to one side of said handle portion; said latch arm clearance aperture is open to said one side of said handle portion; and, said latch arm retaining cavity is open to said one side of said handle portion.
6. The combination door handle and latch as defined in claim 5, wherein said resilient means retaining pocket is defined by a flange extending outwardly from the other side of said handle portion.
7. The combination door handle and latch as defined in claim 1, wherein said resilient means retaining pocket is generally cylindrical in shape and is coaxially disposed with said latch stem receiving aperture.
8. The combination door handle and latch as defined in claim 1, wherein said resilient means is a coil spring.
9. The combination door handle and latch as defined in claim 1, wherein said striker engaging means comprises a bar extending generally transversely from said stem, said bar being adapted to be received through a slot in a striker, and upon rotation of said latch portion, engage and disengage the striker.
10. The combination door handle and latch as defined in claim 1, wherein said coil spring is disposed between the front side of the door and said handle portion to urge handle portion outwardly away from the door and bias said stem arm into abutment with said arm abutment shoulder.
