Description

DESCRIPTION

PARAPET SPECIALLY DESIGNED FOR STAIRS, TERRACES AND

SIMILAR

The present invention refers to a parapet, specially designed for stairs, terraces and the like. In particular, the present invention relates to a parapet consisting of or composed of glass sheets.

Today, parapets with an essential design are especially appreciated.

In particular, parapets are known that consist of a main body consisting of sheets of glass that have to be installed in a vertical position to form a fence.

At the slab-free upper edge, a handrail is attached having a seat adapted to receive the edge when inserted.

To retain the handrail on the edge, a gasket, made of elastomeric material in a U-shape, is inserted into the seat.

This joint also has prominent fins designed to increase the friction exerted by it on the edge of the panel and / or on the inside face of the handrail seat.

In detail, the gasket internally covers the seat surface of the handrail along the entire length of the handrail and is dimensioned such that, when engaged with the edge, it is elastically deformed causing an interference fit.

The problem underlying the present invention is that of increasing the assembly and structural simplicity with respect to known parapets and also improving their structural stability.

The main task of the present invention is to provide a specially designed parapet for stairs, terraces and the like that provides a solution to this problem by solving the aforementioned drawbacks of the parapet described above.

To this end, the objective of the present invention is to provide a specially designed parapet for stairs, terraces and the like that allows to achieve a simpler assembly in relation to traditional parapets.

Another objective of the present invention is to provide a parapet that allows to simplify the assembly, obtaining a greater mutual structural retention of the components.

Another object of the invention is to provide a parapet that does not require the use of skilled labor for its assembly.

In accordance with the attached claim 1, this task, as well as these and other objectives that will be more evident hereinafter, are achieved by a specially designed parapet for stairs, terraces and the like.

The detailed characteristics of the specially designed parapet for stairs, terraces and the like according to the invention are presented in the dependent claims.

Other characteristics and advantages of the invention will become more apparent from the description of a preferred, but not exclusive embodiment of a specially designed parapet for stairs, terraces and the like according to the invention, illustrated by way of non-limiting example in the illustrations attached, in which:

- illustration 1 shows a specially designed parapet for stairs, terraces and the like according to the invention in cross section;

- Illustration 2 shows a specially designed parapet for stairs, terraces and the like according to the invention in side view, in section.

With particular reference to the aforementioned illustrations, generally indicated by (10) is a parapet specially designed for stairs, terraces and the like, which, traditionally, consists of:

- a protection element (11), preferably consisting of a safety glass sheet, having a lower end (11a) that can be fixed to a walking support and an upper end (11b) that extends longitudinally A ;

- a handrail (12), advantageously consisting of a tube made of a metallic material, having a seat (12a) adapted to receive the upper end (11 b) in insertion.

In accordance with the present invention, the parapet (10) has a special feature because it consists of at least one U-shaped fastening element (13) that has:

- a column (13a) adapted to be housed in the seat (12a);

- a compartment (13b) to house an edge (14) of the upper end (11b).

In practice, according to the present invention, it is possible to use a multitude of fastening elements (13) distributed along the edge (14) of the protection element (11), preferably at regular distances, to couple the handrail (12) to the edge (14).

The clamping element (13) has a length less than the length of the upper end (11b), measured in the longitudinal direction A, and is made of a polymeric material selected from acrylonitrile butadiene styrene or ABS and an aliphatic polyamide, generally known as nylon , preferably reinforced with advantageously glass fibers.

Furthermore, the clamping element (13) is dimensioned with respect to the seat (12a) of the handrail (12) and the edge (14) of the upper end (11b) to interfere with at least one of the latter.

It has been verified that keeping the handrail (12) attached to the Protection (11) is increased thanks to the use of the clamping element (13) with respect to traditional parapets, despite the fact that the clamping element (13) connects the handrail (12) to the protection element (11) only in one series of points and not continuously as in traditional parapets.

In a preferred but not exclusive embodiment of the present invention, the parapet (10) is advantageously composed of a first locking element (15) having a first adhesive face (15a) fixed to the column (13a) and a second adhesive face (15b) attached to the bottom of the seat (12a) to lock the first locking element (15) to the handrail (12).

Depending on contingent needs, the parapet (10) can comprise, alternatively or in combination with the first blocking element (15), a second blocking element (16) having a first adhesive face (16a) fixed to the edge (14 ) and a second adhesive face (16b) fixed to an internal wall (17) of the compartment (13b) to lock the fastening element (13) to the protection element (11).

The first locking element (15) and / or the second locking element (16) preferably consist of a double-sided adhesive tape.

Advantageously, the first blocking element (15) is made with a double-sided adhesive tape selected from:

- the product currently known as 3M company code PFR-4616 or

- the product that is currently known by the 3M company VHB code, in case a higher gripping force is required.

If particularly effective adhesion is required, edge (14) can preferably be covered with a suitable primer to facilitate adhesion of the first adhesive face (15a) to edge (14). Advantageously, said primer is a product of the 3M company known by code 94.

Before applying the primer, advantageously the edge (14) and / or the compartment (13b) will be cleaned with a solvent selected from acetone and isopropyl acid, preferably by a cloth that will move in only one direction.

As explained above, advantageously the parapet (10) consists of a multitude of fastening elements (13) which preferably have a length of between 30 mm and 100 mm, and more preferably equal to 60 mm. They are also placed at a mutual distance in the longitudinal direction A, advantageously included between 100 mm and 300 mm and preferably equal to 180 mm.

With special reference to the previous illustrations, the clamping element (13) advantageously consists of a flat lower part (131), and two side walls (132 and 133) that extend perpendicular to the lower part (131) to form a profile U-shaped square adapted to engage edge (14) which is preferably square.

In general, compartment (13b) will be complementary to edge (14), but with smaller dimensions to engage the latter with interference. For example, in the case of an edge (14) having a thickness of 17.52 mm, the width of the compartment (13b), defined by the distance between the side walls (132 and 133), will preferably be 16.76 mm , where the side walls (132 and 133) will preferably have a thickness of about 2.4mm and the bottom a thickness of about 2mm.

In accordance with the present invention, when using a parapet (10) the fastening element (13) can be coupled on two consecutive protection elements (11) to help mutual fastening and coplanarity, thus simplifying the installation of the parapet itself ( 10).

The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of protection of the appended claims.

Furthermore, all the details can be replaced by other technically equivalent elements.

In practice, the materials used, as well as the contingent shapes and dimensions, may vary depending on contingent requirements and available technology.

When the characteristics and construction techniques mentioned in the following claims are accompanied by reference signs or numbers, said reference marks or numbers are affixed for the sole purpose of increasing the intelligibility of the claims themselves and, consequently, do not constitute a restriction. to the interpretation of each element identified, merely by way of example, by means of said signs or reference numbers
