Stair handrail mounting bracket

Abstract

A stair handrail mounting bracket facilitates the installation of handrails, the bracket including a series of elements that make it, mechanically, a fixed support of the handrail anchored to the nosing of the steps, allowing the automatic and uniform positioning at a level of the handrail for the whole length of the stairs before it is fixed to the wall. The mounting bracket includes two support bases, a system of clamping elements including a clamp provided with a threaded bar that can be adjusted via a nylon knob. The nylon know allows the tightening or loosening of the support that anchors the bracket support bases to the stair step nosing. The bracket support bases includes two sliding tracks on which to slide a support bar that can be locked in place as required with two geared knobs.

1 . Stair handrail mounting bracket facilitating installation of handrails and being, mechanically, a fixed support of a handrail anchored to a nosing of steps so as to allow automatic and uniform positioning at a level of the handrail for an entire length of the stairs before being fixed to the wall, said mounting bracket comprising:
 two support bases;   a system of clamping elements being comprised of a clamp provided with a threaded bar, said threaded bar being adjusted via a nylon knob, said nylon know tightening or loosening support anchoring the support bases to the stair step nosing, the support bases being comprised of two sliding tracks, a support bar being slidable on the sliding tracks and locked in place as required with two geared knobs, further comprising, for stair steps without nosing or steps that are rounded, a 20/25 kg weight provided by a piston inserted in an opposite end of the support bar.   
   
   
       2 . Handrail mounting bracket as claimed in  claims 1 , wherein said clamp is adjusted via a nylon knob, tightening or loosening of anchoring supports on the stair step nosing. 
   
   
       3 . Handrail mounting bracket as claimed in  claim 1 , wherein said support bases have two sliding tracks and a support bar inserted on the tracks, said support bar being telescopic so that the handrail can also be supported and adjusted according to the width of the stairs on which the handrail is to be installed and that can be locked as required via two geared knobs. 
   
   
       4 . Handrail mounting bracket as claimed in  claim 1 , wherein said support bar is telescopic, adapting according to the width of the stairs on which the handrail is to be installed. 
   
   
       5 . Handrail mounting bracket as claimed in  claim 1 , further comprising:
 a locking system being comprised of a threaded bar and a quick clamp respectively supporting and adjusting the support base both widthways and vertically according to the pitch lines of the stairs, being locked in place before proceeding to fix the base to the stair load-bearing wall.   
   
   
       6 . Handrail mounting bracket as claimed in  claim 1 , wherein each support base adjusts both widthways and vertically according to the pitch lines of the stairs. 
   
   
       7 . Handrail mounting bracket as claimed in  claim 1 , further comprising:
 for steps without nosing, a 20/25 kg weight, the support base being inserted inside the weight.
