Description

DESCRIPTION

COUNTERWEIGHT FOR FIXED SELF-SUPPORTING RAILING

OBJECT OF THE INVENTION

The present invention refers to a counterweight for a fixed self-supporting railing, usable on roofs of finished buildings to protect against falls.

BACKGROUND OF THE INVENTION

At present, fixed self-supporting railings are known, widely used on roofs of finished buildings, and which comprise L-shaped uprights whose upper branch is fixed to transversal elements that form a barrier, and whose lower branch is resting on the ground. (on the upper face of a slab, for example), with the counterweight mounted on said lower branch. This materializes a fence with greater stability the greater the length of the lower branch of the uprights and the greater the counterweight.

As the lower branch of the pillar is not very long to minimize the risk of tripping, the best way to improve stability is to increase the mass of the counterweight. This has the drawback that the counterweights become difficult to handle and machinery is needed to carry and place them, also slowing down the work and increasing the danger.

DESCRIPTION OF THE INVENTION

The counterweight for a fixed self-supporting railing of the invention is of the type used in railings that comprise L-shaped uprights, on whose upper branch are fixed transversal elements that make up a barrier, and whose lower branch is resting on the ground ( for example, on the upper face of a slab), with the counterweight being mounted on said lower branch, where according to the invention, in its most fundamental version, the counterweight comprises a practicable drawer provided with a lower tunnel in a complementary way to that of the lower branch of the upright (that is, capable of accommodating it). This allows the empty counterweight to be carried and filled with sand or other material. heavy at the time of placement for use, achieving sufficient weight, facilitating the assembly of the fence and speeding up the work and reducing the danger, taking into account that the existing counterweights weigh from 12.5 to 25 kg and up.

That is, the counterweight is transported empty and stacked, reducing weight and cubic capacity in transport.

BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 shows a view of the counterweight of the invention with the drawer open.

Figure 2 shows a view of the counterweight of the invention with the drawer closed.

Figure 3 shows a view of a fence supported by the lower branch of one of its uprights by means of two counterweights of the invention.

DESCRIPTION OF A PRACTICAL EMBODIMENT OF THE INVENTION

The counterweight (1) for the fixed self-supporting railing (2) of the invention is used in fences of the type that comprise L-shaped uprights (3) (see fig. 3), in whose upper branch (31) elements are fixed. crossbars (20) that make up a barrier, and whose lower branch (32) is resting on the ground (4) (for example on a roof), with the counterweight (1) being mounted on said lower branch (32), where from According to the invention (see figs. 1 and 2), the counterweight comprises an openable drawer (5) provided with a lower tunnel (6) complementary to that of the lower branch (32) of the upright (3).

Preferably, the drawer (5) comprises a lower sector (50) with a bottom (51) and side walls (52), and an openable upper cover (53), which is found covering the entire upper surface of the drawer (5). This makes it easy to fill and empty quickly.

In addition, it is preferred that the lower sector (50) have the side walls (52) inclined in decreasing section towards the bottom (51), which allows the lower sectors to be stacked together with a fit between them and a reduction in space. busy, facilitating transport and storage.

In addition, in this preferred example of the invention, it has been provided that the drawer (5) comprises an upper front projection (55) and a complementary upper rear recess (56), which allows several drawers to be arranged consecutively in a row, assembled at their ends to configure a larger counterweight, as seen in fig. 3.

In the figures, it can also be seen how the drawer (5) can include a handle (57), which facilitates carrying it. Said handle (57) is ideally located near the upper front projection (55), which allows it to have a width capable of being grasped with one hand.

In addition, provision has been made for the drawer (5) to include through holes (59) in positional coincidence with the tunnel (6), including screws (8) through said holes (59) for fastening to the lower branch (32). of the upright (3). This allows the screw closest to the edge to be screwed in first, which will serve to level the studs. Next, the other screws will be screwed in without tightening too much so as not to lose leveling. Finally, it will be verified that it is still level. In this way, self-levelling is achieved in a simple way, thus adapting to all roofs, absorbing their inclination. Said holes (59) are at different distances from each other, to configure a single placement position on corresponding holes (33) of the lower branch (32) of the upright (3). In fact, this self-leveling allows you to do without shims, wedges or the like, which are used to level this type of fence.

Having sufficiently described the nature of the invention, as well as the manner of carrying it out in practice, it should be noted that the provisions indicated above and represented in the attached drawings are subject to modifications in detail as long as they do not alter the fundamental principle.
