Abstract

Stair handrail mounting bracket that facilitates the installation of handrails, comprising a series of elements that make it mechanically a fixed support of the handrail anchored to the nosing of the steps so allowing the automatic and uniform positioning at level of the handrail for the whole length of the stairs before it is fixed to the wall. The mounting bracket may comprise two support bases (1), a system of clamping elements consisting of a clamp (2) provided with a threaded bar (3) that can be adjusted via a nylon knob (4) that allows the tightening or loosening of the support that anchors the bracket support bases to the stair step nosing. The bracket support bases may consist of two sliding tracks (7) on which to slide a support bar (6) that can be locked in place as required with two geared knobs (8).

Description

Title: Stair handrail mounting bracket.
Field of invention
The present invention relates to a bracket whose component parts facilitate the installation of stair handrails because they allow the worker to keep the handrail mechanically fixed to the stair steps before it is fixed to the load- bearing wall so as to guarantee the automatic and uniform positioning of the handrail at level for the whole length of the stairs. Background Currently, installation of stair handrails is carried out manually and needs to be done by several workers whose number is proportional to the length of the stairs.
In particular, today there do not exist tools that will allow the mechanical locking of the handrail before it is finally fixed to the load-bearing wall of the stairs, with the result that it is particularly difficult to position the handrail at a uniform level for the whole length of the stairs. Disclosure of invention
It is an object of the present invention to provide users with a handy, light and inexpensive bracket that will make it easier to install a stair handrail with the prior mechanical locking of the handrail to the stair steps before it is fixed to the load-bearing wall so as to facilitate the automatic and uniform positioning of the handrail at level for the whole length of the stairs. It is another object of the present invention to provide workers with a simple, inexpensive tool that will eliminate the problems described above. It is another object of the present invention to reduce the labour required so as to lower the cost of installing stair handrails and in any case to facilitate and improve their installation. These and other objects are achieved by the stair handrail mounting bracket whose components mechanically define its function of fixed handrail support anchored to the nosing of the stair steps, that is, to their protruding part, before the handrail is fixed to the load-bearing wall, so as to facilitate the installation of the handrail and, in particular, its automatic and uniform positioning at level for the whole length of the stairs. For stair steps without nosing or steps that are rounded, and therefore such that the bracket cannot be anchored, the present invention has a variant whereby the prior fixing of the bracket to the step is brought about by a 20/25 kg weight provided by a piston that is inserted in the opposite end of the support bar on which the handrail support and locking base is mounted. Detailed description
Other characteristics and advantages of the invention will become more readily apparent from the description of a preferred but not exclusive embodiment, of the invention illustrated by way of non-limiting example in the accompanying drawings, in which:
Fig. 1 is a view of the invention of the present application complete with all its functional parts; Fig. 2 shows the two support bases of the system on the step; Fig. 3 is a view of the clamp for clamping the support bases to the step;
Fig. 4 shows the support bar, which is preferably telescopic so that the bracket can also be adjusted according to the width of the stairs on which the handrail is to be installed; Fig. 5 represents the handrail support base with its locking system; Fig. 6 is a view of the invention with the variant envisaged in the case of steps without nosing or rounded steps. The invention consists of a stair handrail mounting bracket made up of a system for mechanically fixing it to the stair steps consisting of two support bases (l) .and (I/a) that are anchored to the nosing of the steps with a clamping clamp (2) provided with a threaded bar (3) that can be adjusted via a nylon knob (4) to allow tightening or loosening of the anchoring supports (5) and (5/a) on the stair step nosing. The support bases (1) and (I/a) have two sliding tracks (7) and (7/a) on which are inserted a support bar (6) that can be locked as required via two geared knobs (8) and (8/a). The support bar (6) is preferably telescopic so that the invention can also be adjusted according to the width of the stairs on which the handrail is to be installed.
A threaded bar (9) is welded on the outside of the bracket and its purpose is to support and adjust the support base of the handrail (10) both widthways and lengthways according to the pitch lines of the stairs so that, once the handrail has been placed at uniform level after being locked with a quick clamp (11), it can easily be fixed to the stair load-bearing wall.
In the case where the stairs have steps without nosing or with their final part rounded, the above described invention has the variant of replacing the above described fixing system with one of a 20/25 kg weight (12) that is inserted inside the support bar (6) and fixed to it with a pin (13). In this variant, the invention will have just one support base (1) on the step and it will be adjusted to the height of the step via the threaded bar (3) and the nylon knob
(4).
The materials and dimensions of the invention as described above, illustrated in the accompanying drawings and claimed below, may be any according to requirements. Moreover, all the details can be replaced with other technically equivalent ones.

Claims

1. Stair handrail mounting bracket that facilitates the installation of handrails, characterized by a series of elements that make it mechanically a fixed support of the handrail anchored to the nosing of the steps so allowing the automatic and uniform positioning at level of the handrail for the whole length of the stairs before it is fixed to the load-bearing wall.
2. Handrail mounting bracket as claimed in claim 1 characterized by two support bases for anchoring it to stair steps with nosing.
3. Handrail mounting bracket as claimed in claims 1 and 2 characterized by a system of clamping elements consisting preferably of a clamp provided with a threaded bar that can be adjusted via a nylon knob that allows the tightening or loosening of the support that anchors the bracket support bases to the stair step nosing.
4. Handrail mounting bracket as claimed in claims 1, 2 and 3 wherein the bracket support bases consist of two sliding tracks on which to slide a support bar that can be locked in place as required with two geared knobs.
5. Handrail mounting bracket as claimed in claims 1, 2, 3 and 4 characterized by a telescopic support bar so as to also adapt the functionality of the invention according to the width of the stairs on which the handrail is to be installed.
