DESCRIPTION

ARTICULATED SUPPORT FOR IMPROVED SAFETY NETS

OBJECT OF THE INVENTION

The object of the present invention is an improvement of a product already on the market, specifically a support for safety nets. The scope of the present invention is that of protection and safety systems in works and buildings.

A support for networks has the mission of supporting a safety net along the entire perimeter of a work, so that objects or people cannot fall into the void. This operation, in multi-storey buildings, is repeated in each of them, having to adapt the network to the specific geometric shape of each work. In the construction of bridges and aqueducts, we also find an important field of application for the innovation that is presented.

BACKGROUND OF THE INVENTION

Advances in buildings and in the materials used make works and buildings continually present more complex geometric shapes, with the consequent need to improve their ability to adapt to the contour of the elements adjacent to them. The supports of the safety nets have the need to adapt also to the new demands, and therefore they also have to be able to be more flexible and modular.

The invention presented is an improvement on a utility model, U201031252, from the same owner as the one requested and where the experiences accumulated during the almost 10 years of exploitation of the previous model have been implemented.

As the invention is an improvement over an existing utility model, the explanation of the invention is proposed as the explanation of the improvements that the requested model presents compared to the existing model.

Thus, the improvements can be included in the following 3 sections:

1. At a geometric level, the improvements that are presented are:

1.1. Several of the pieces, the initial arm (3) and the final arm (6), are now modular, being assembled together and allowing both arms to have a variable length. In order to make the different arms assembled with each other and with the angular sphere (5), the system requires that the arms, initial (3) and extension (4), have two sections of rectangular metal tube, a smaller one with an outer section equal to the inner section of a larger one. Thus, it is observed how the initial arm (3) has a smaller tube (3.1) and a larger tube (3.2), where the smaller tube (3.1) can be inserted into the larger tube (3.2) of another initial arm (3) of greater or lesser length, generating a new initial but modular arm, whose length is the sum of the lengths of its components. In order to ensure this union of several arms, another characteristic is required, and that is that they all have a clamping element at their ends. This fastening element is the existence of a through hole that all the articulated arms of the proposed system have at their assembled ends. Thus, the smaller tube (3.1) has a through hole (3.1.1) located at a certain distance from the nearest end, at this distance we call it “a”, and it is equal to or less than the distance from the other end from the arm to the through hole of the larger tube (3.2.1). This distance "a" remains unchanged at one end of all the arms of the system. Thus, "a" is the distance between the through hole (3.1.1) and the closest end of the initial arm (3), between the through hole (4.1) and the closest end of the extension arm (4), it is appreciated between the through hole (5.1) of the angular sphere (5) and the closest end of the tube and it is also present between the through hole (6.1) and the closest end of the end arm (6) and allows that when we assemble two arms , the through holes can be faced and with a through screw the joint is fixed. All the arms of the system have these two through holes at both ends, except for the final arm (6), which only has it at one of its ends, which forces it to assembly, at the other end it has a flange (6.2) destined to fix the safety net, which prevents any supplement from being added.

The angular sphere (5), which allows the articulation between the arms, is now independent allowing two previously impossible configurations:

- Possibility of the net support having three arms, two initial arms (3) and a final arm (6), an initial arm (3) plus an extension arm (4) plus a final arm (6) or any of the possible combinations where the existence of two independent angular spheres (5) allows the coexistence of several articulated arms. This configuration is shown in figure 7.

In order to be able to couple the different arms to the angular sphere (5), the system has a novel characteristic. The angular sphere has a distance "b", which is the distance between the through holes (5.3.1.1) located in the center of the semicircular plates (5.3.1) and the set of through holes (5.3.1.2) located in the circular contour of the plates (5.3.1). This distance "b" is fixed for the whole system, and we also find it in the initial arms (3) between their through holes [(3.1.1) and (3.1.2)] and in the extension arm (4) between their through holes [(4.1) and (4.2)]. If any of the mentioned arms is inserted between the two metal plates (5.3.1) and faces, the through hole (3.1.1) of the initial arm (3), with the through hole (5.3.1.1) of the angular sphere (5) by passing a screw between them, the initial arm (3) and the angular sphere (5) would be fixed. If we also match the through hole (3.1.2) of the initial arm (3) with any of the through holes (5.3.1.2) of the contour of both plates (5.3.1) and we pass a screw through all the through holes Now, in addition to fixing the initial arm (3) to the angular sphere (5), we achieve a certain angle between them.

- Possibility that the angular sphere (5) can now be attached directly to the anchor, without the need for an initial arm (3), bringing the net closer to the anchor. This configuration is shown in figure 8 and figure 9.

To have this mounting possibility, the arm of the angular sphere has a through hole (5.1) in the vicinity of its end, this hole located at a distance "a" from the closest end of the arm, a characteristic that it shares with the rest of the system. The section size such that it allows it to be inserted into the larger tube of an initial arm (3.2) and that it matches in size with the rectangular metal tube (1.3) of the straight anchor (1). Making the through hole (5.1) of the angular sphere (5) coincide with the through hole (1.3.1) of the straight anchor (1) when we insert them, and passing a through screw, both are firmly joined.

Reasons and advantages:

The reasons are various, although the main reason is the adaptability of the system to the different geometries of the buildings. Having the different interchangeable pieces, even with pieces of the same function and variable length, offers the possibility of adapting the arms to the safest geometry for each occasion. Thus, the initial arm (3), with the same design, is manufactured in lengths of 0.5m, 1m and 2 meters, all of which can be assembled together and with the straight box (1), the angular box (2), the angular sphere (5), the end arm (6) and the extension arm (4).

Thus, we can minimize the drop space at the edge as much as possible, making the system safer. Also, it is possible to extend the height of the last post, being able to raise the shielding above the meter as much as necessary, even if the protection needs to evolve during the work.

Another reason is due to logistics, since the arms of 2.5 meters and above (used in the previous model) have drawbacks in ordinary shipments and special transports are needed. By making independent pieces of no more than 2 meters, it allows to use and transport the material by ordinary transport. In addition, we lighten the weight and handling of the operator, allowing better ergonomics in assembly and being more easily manipulated.

At a functional level, the new angular sphere (5) allows a greater degree of inclination, between 180 ° to 90 °, which allows a better adaptation to more complex geometries, with projections or corners. The new angular sphere (5) allows greater scaling, as it has more intermediate through holes that adjust the angle of the post where the net is subsequently incorporated, allowing the tightest screening and reducing the fall corridor.

New parts:

edge of the slab, extending the protection to applications in roof enclosures or other spaces that need this type of shielding when there is no possibility of placing scaffolding. Also, the new straight box (1) reduces the space required for screwing, since physical space is sometimes limited and this type of solution is needed as shown in figure 8.

These 3 points make this system improvement a more versatile and adaptable product to more real cases on the market, offering a greater range of protection against different geometries, or different needs in the execution of viaducts and building or rehabilitation works. .

BRIEF DESCRIPTION OF THE DRAWINGS

As a complement to the exposed descriptions, nine drawings are attached where, by way of illustration, and not limitative, the characteristics of the invention that it is intended to register are displayed, for a better understanding of it. Thus, the following has been represented:

Figure 1: Shows an image of a perspective view of the straight box (1), used to anchor the support on surfaces where the anchoring space is reduced and where the initial arm (3) comes out perpendicular or parallel to it.

Figure 2: Shows an image of a perspective view of the angular box (2), used for surfaces where the initial arm (3) presents some angle with the anchoring surface.

Figure 3: Shows a perspective image of one of the possibilities, according to its length, that the initial arm (3) may have. Keeping unchanged the distance between the through hole (3.1.1) and its nearest end, called “a”, and the distance between the through hole (3.1.1) and the adjacent through hole (3.1.2), called “b ", This piece of the set can have several total lengths between its ends, which are: 0.5 meters, 1 meter and 2 meters.

Figure 4: Shows a perspective image of an extension arm (4), used to provide an extra length to either of the two arms, initial (3) or final (6).

Figure 9: Shows a perspective image of the articulated support for improved safety nets where you can see an assembly without initial arm (3) with the angular sphere (5) in direct connection with an angular anchor (2) and with the final arm formed by the union of an initial arm part (3), an extension arm part (4) and a final arm part (6).

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures, we can see in them an example of a preferred embodiment, which comprises the parts and components described below.

The assembly in question would be composed of:

- A straight anchor (1).

- An extension arm (4).

- Two angular spheres (5).

- An intermediate arm composed of the union of two pieces: an initial arm (3) of 0.5m length and another extension arm (4).

- A final arm composed of the union of two pieces: a lower arm (3) in its 0.5m length and a final arm (6).

and can be seen in figure 7.

Thus, as seen in figure 1, the straight anchor (1) is made up of two square metal plates [(1.1) and (1.2)] joined by one of their sides and The future anchoring screws will go to the building, having two possible fastening positions that differ 90 ° between them. Welded to one of the metal plates is a rectangular profile (1.3) of metal tube of sufficient section to house an extension arm (4) inside, which once embedded is fixed with a through screw through the through hole (4.1) of the same and the through hole (1.3.1) of the straight anchor (1).

The extension arm (4) is made up of the permanent union of two rectangular metal tubes, one prepared to be inserted into other elements of the system and the other prepared to receive different elements of the system. Both subcomponents of the extension arm (4) have separate holes, whereby a through screw the elements that receive and the elements that are coupled are fixed.

The next element of the assembly is the angular sphere (5), which enables articulation between the different arms of the system. The sphere is made up of a rectangular metal profile at one end of which two 180 ° circular sectors (5.3.1) are attached to two opposite sides so that the sectors face each other. Both circular sectors have a hole (5.3.1.1) in their center and a set of holes (5.3.1.2) equidistant from the first, in a fixed length for the entire system called "b", and arranged on the periphery of each of the circular sector shaped plates (5.3.1).

As reported, the angular sphere (5) is attached to the extension arm (4) by inserting one end of it on one of the sides of the extension arm (4) and the connection is fixed by means of a through screw that passes through the through hole ( 5.1) or the through hole (5.2), of the angular sphere (5), and the through hole that the extension arm (4) has on that side.

The next step is to fix, among themselves and with the first angular sphere (5), the different components of the intermediate arm. This is made up of the union of two pieces, an initial arm (3) of length 0.5m and an extension arm (4). These can be joined because the initial arm (3) is formed from two rectangular metal tubes [(3.1) and (3.2)] with sections such that they can be inserted into the different elements of the system and that the different elements of the system can be inserted into they. Thus, at one end of the initial arm (3) we have a through hole (3.1.1) so that when said end is inserted into any of the elements of the system, or even at the opposite end of the other lower arm (3.2), Thyme thru leaves both elements firmly together.

At this point in the assembly we already have two articulated arms joined by an angular sphere (5) and all this anchored to the building by means of the straight anchor (1). To achieve coupling of the final arm, third arm of the set, a second angular sphere (5) is coupled to the end of the extension arm (4) so that the angular sphere (5) is inserted and by means of a through screw that passes through a through hole ( 5.1), both are firmly fixed.

The coupling of the final arm with the angular sphere (5), identical to the coupling between it and the intermediate arm, begins with the coupling between the angular sphere (5) and an initial arm (3) in its shorter version, 0 '5m, by inserting the thinnest end (3.1) of the initial arm (3) between the metal plates (5.3.1) of the angular sphere (5). Thus, if we pass a screw through the through hole (5.3.1.1) of the plates and the office (3.1.1) of the lower arm (3), arm and sphere are joined but with the possibility of turning between them. To fix the angle between both, a second through screw will go through the through hole (3.1.2) of the thinner tube (3.1) of the initial arm (3) and one of the through holes (5.3.1.2) of each of the plates metallic elements (5.3.1) of the angular sphere (5).

Joining the upper arm (6) at its end with a through hole (6.1), with the end (3.2) of the lower arm and its through hole (3.2.1), both remain embedded. By passing a through screw through both through holes, which face the coupling, the joint is firmly fixed.

Thus, the assembly of an articulated support for safety nets is included, where the net will be anchored to the beam (6.2) located at the upper end of the final arm (6) and to the construction element it protects, preventing any object or person from fall into the void.
