Abstract:
A fitting for holding an upright suspension rod, which extends from a motor casing, to a ceiling wall, said fitting comprising:a mounting frame including right and left anchoring members spaced apart from each other with a first width in a transverse direction, and adapted to be fixed on the ceiling wall, each of said right and left anchoring members having first inner and outer edge portions opposite to each other in the transverse direction, and right and left arm members respectively extending from said first inner edge portions of said right and left anchoring members downwardly and in a longitudinal direction transverse to the transverse direction to form right and left jaw portions spaced apart from each other, and provided respectively with right and left anchored walls, each of which extends in the transverse direction and includes second inner and outer edge portions opposite to each other in the transverse direction, said second inner edge portions of said right and left anchored walls defining a second width shorter than said first width so as to be adapted to hold the upright suspension rod, each of said right and left anchored walls defining a fastening bore therein which extends in the longitudinal direction; a protective cover member including an annular abutment wall confining a central opening adapted to accommodate passage of the upright suspension rod, and extending in the transverse direction and disposed beneath said right and left anchored walls, said annular abutment wall defining a pair of through holes which are registered with said fastening bores, respectively, and a skirt portion extending circumferentially from said annular abutment wall and towards the ceiling wall, and outwardly so as to flank said first outer edge portions, thereby concealing said mounting frame; a pair of fastening members, each oriented in an axial direction, and including an enlarged head with a thickness in the axial direction, a distal shank portion of a first dimension, and a proximate shank portion interposed between said enlarged head and said distal shank portion, and being of a second dimension which is larger than said first dimension so as to form an abutment shoulder between said proximate and distal shank portions such that when said fastening members are respectively brought to be inserted into said fastening bores to fasten said annular abutment wall onto said right and left anchored walls, said abutment shoulders of said fastening members abut against said annular abutment wall; and an annular shield member including upper and lower annular walls spaced apart from each other in the longitudinal direction, said upper annular wall including a pair of insert grooves diametrically opposed to each other, and each of such a dimension as to accommodate said enlarged head of a respective one of said fastening members in the longitudinal direction when the axial direction is oriented to conform to the longitudinal direction, and a pair of clamping grooves communicated with and extending from said insert grooves in one of clockwise and counterclockwise directions such that once said insert grooves have been brought to receive said enlarged heads in the longitudinal direction respectively, a subsequent rotation of said upper annular wall of said annular shield member relative to said annular abutment wall of said protective cover member, which is guided by said proximate shank portions respectively along said clamping grooves, will bring said enlarged heads to be retained respectively in said clamping grooves.
