Abstract

Safety rail support for use on roof has trough-section base and adjustable tubular frame for supporting transverse bars or mesh.

Description

 The present invention relates to a protective railing to ensure the safety of people working on a building roof during roofing work, in particular repair.

 Various systems are currently used during work on the roof to ensure the safety of people: individual support harness, scaffolding or barrier at the bottom of the roof.

 The first system has the disadvantage of interfering with the movements of people and of not allowing long work with such a system. The scaffolding is bulky, long in its installation and expensive to purchase. The other barrier systems are cumbersome in their installation and furthermore do not make it possible to replace the gutters at the bottom of the roof once the barrier has been placed.

 The device according to the invention overcomes these drawbacks.

It is in fact made up of uprights, interconnected by bars, the assembly being disposed at the bottom of the roof, thus forming a barrier.

 The essence of the invention resides in the constitution of the uprights.

 These are similar and form unique objects that can be handled very easily. After removing the first two rows of tiles, in the case of a repair, the uprights, which consist of a sole, are fixed to the roof, ideally by means of a screw, by the person ensuring the implementation barrier place. The shape of the upright, made up of tubes, allows the displacement of two sliding tubes one inside the other, to adapt to the inclination of the roof, so as to have a barrier perpendicular to the roof. The tilt is then immobilized by means of a pin.

 The different uprights being fixed on the width of the roof, these can be connected together by means of transverse bars so as to stiffen the assembly laterally.

 The uprights and the bars in place, nets and / or boards can be arranged horizontally on the uprights in order to stop any untimely fall of objects or people.

 An offset, present in the lower part of the uprights, outside the roof, allows to change the gutters at the bottom of the roof, and this, while being protected by the barrier.

 When the barrier is removed, the uprights can be folded up so that they require less space during storage.

This function is also given by the sliding of the two tilt adjustment tubes.

The accompanying drawings illustrate the invention
Figure 1 shows a perspective view of the assembled assembly.

 Figure 2 shows a perspective view of the amount to assess its constitution.

 Figure 3 shows a perspective view of the sole alone.

 With reference to these drawings, the device consists of uprights (1), fixed on the roof where it is necessary to intervene (2), after having removed the first and the second row of tiles (3). The uprights are interconnected by means, for example, of bars (4) fixed on the uprights.

The device is completed by the installation of boards (5) and / or safety net (6) partially shown on the uprights.

 The shape of the uprights (1) in the lower part of the gutter side (7) allows this last barrier to be changed in place.

 The uprights consist of a sole (8) for fixing the upright on the roof. For this, the sole is pierced (9) for the passage of a screw. An option not shown consists, thanks to a tapping of the soleplate, of holding the screw in place so as not to lose it during its disassembly.

 The general U shape of the sole (8) makes it possible to articulate thereon, two tubes (10) (11) by means of axes of rotation shown diagrammatically (12) (13). The curved shape of the tube (11) allows, thanks to an offset relative to the fixing base (8), to change the gutter barrier in place.

 The tube (11) is reinforced by another tube (14) and a spider (15), so as to stiffen the upright, as shown in Figure 2. The spider can also be used to support the boards (5).

 At the end of the tube (11) is welded a yoke (16) on which another tube (17) is articulated by means of a rotation axis (18) shown diagrammatically. This last tube (17) has a large diameter making it possible to form a slide with the tube (10), of smaller diameter. It is this slide which makes it possible to adjust the amount at the inclination of the roof as well as limiting the size of the amount when it is stored.

 Holes present in the tubes (10) and (17) allow the slide to be immobilized by means of a pin (19).

 The upright (1) has in its upper part a rectangular tube (20) which makes it possible to fix the transverse bars (4) between the uprights by means of a screw (21).

 By way of nonlimiting example, the amount will have a height of the order of 120 cm and a width of 40 cm, slide deployed.

 The device according to the invention is particularly intended to meet current economic and safety requirements, on roofing sites.

Claims (4)
