ABSTRACT:
A torsion spring door closer assembly for use with a in-swinging, out-swinging, right-handed or left-handed door. The door closer assembly is reversible so that it can be easily adapted to the various door styles above. Further, the closing force provided by the assembly can easily be adjusted. The door closer assembly includes a torsion spring (58) and a housing (56) comprising a top portion (60) and a bottom portion (62). The top portion (60) is disposed for angular movement relative to the bottom portion (62). Attached to one of the top and bottom portions of the housing is a known door closer assembly comprising a cylinder (52) and a rod (54) extending therefrom. The door closer further comprises a mounting bracket (76) which cooperates with the door closer to provide the features of reversibility, and adjustability of the door closing force.
