Abstract:
The present invention relates to an elevator handrail supporting device including: a fixing plate assembly  20  and a bracket  50  coupled to the fixing plate assembly, in which the bracket includes T-nut guides  60 , a T-nut  70  coupled to the T-nut guides, a stopper  80  being in contact with a bolt head, a bolt support  90 , and a catching projection  96 , and when the bracket  50  is fitted with the fixing plate assembly  20  coupled to a handrail  10 , a stepped portion  94  of the catching projection  96  is engaged with and coupled to a catching hole  24 , a bolt is fitted into a fastening hole  22 , and then the bolt is tightened into a threaded hole  76  of the T-nut  70 , the fixing plate assembly  20  is bent downward by elasticity so as to apply an upward force to the handrail  10.

Claim (Index 1):
An elevator handrail supporting device comprising:\n a fixing plate assembly  20  which is fixed, by a bolt  8 , to a circumferential surface of a cylindrical handrail  10  installed in an elevator cage, has an L-shaped cross section, has a fastening hole  22  and a catching hole  24  penetratively formed at a center of a bottom surface and at an edge of the fixing plate assembly  20 , respectively, and has elasticity; and a bracket  50  which is coupled to the fixing plate assembly  20 , has an inverted U-shaped cross section, has one end portion having a curved line coincident with a circumferential surface of the handrail  10  in a coupled state, and has the other end portion coupled to a wall surface of the elevator cage, wherein the bracket includes: T-nut guides  60  which are horizontally disposed with a space formed between the T-nut guides  60  and an inner upper end portion of the bracket, have a guide slot  62  at a center in a longitudinal direction, and are disposed in a plate shape at both sides of the guide slot; a T-nut  70  which is moved along the guide slot  62  of the T-nut guides  60 , has a main body  74  inserted into the guide slot, wings  72  horizontally protruding at both sides of an upper end of the main body, and a threaded hole  76  vertically formed in the main body  74 , and has a T-shaped cross section; a stopper  80  which protrudes downward at one end portion of the T-nut guide  60 , and is in contact with a bolt head of the bolt  8  for fixing the fixing plate assembly  20  to the handrail  10  in an assembled state; a bolt support  90  which is vertically formed in the bracket in the vicinity of an end portion of the bracket  50  opposite to the handrail, and has a hole  92  sized to allow a main body of a fastening bolt to pass therethrough and a bolt head of the fastening bolt to be caught; and a catching projection  96  which vertically protrudes at a lower end portion of the bolt support  90 , has a stepped portion  94  formed at a connecting portion between the catching projection  96  and the lower end portion of the bolt support, and protrudes downward from the catching hole  24  in the assembled state in a state in which the stepped portion  94  is caught by the catching hole  24  of the fixing plate assembly  20 , and when the bracket  50  is fitted with the fixing plate assembly  20  coupled to the handrail  10 , the stepped portion  94  of the catching projection  96  is engaged with and coupled to the catching hole  24 , the bolt is fitted into the fastening hole  22 , and then the bolt is tightened into the threaded hole  76  of the T-nut  70 , such that the fixing plate assembly  20  is bent downward by elasticity so as to apply an upward force to the handrail  10 .
