Abstract

Improvements in the object of the main patent nº 9900807 for "Safety guard for floor formwork". The improvements provide for the realization of the fixing hook of the protection net on the struts of the formwork, by means of a single steel rod that has two straight arms joined together by means of a circular eyelet made on the rod itself, finishing one of said arms in a flattened area and finishing the other arm in an extreme area that has two successive hooks, the first one for retention at the edge of the hole of the right foot and the second safety, preventing its accidental detachment.

Description

Refinements in the object of the patent main no. 9900807 by: "Formwork safety guard of floor ".

The present addition refers to some improvements introduced in the object of the main patent 9900807 for "Safety guard for floor formwork" which provide sensible advantages over the purpose of said Main patent, for its novelty and activity characteristics inventive about it.

The main patent disclosed a protector constituted by elongated laminar elements adaptable to the spans of every two parallel alignments of the struts of floor formwork support, with suspension elements that are introduced into holes in the struts, using hooks special.

The industrial practice of the object of said Main patent has led the inventor to develop new ones hooks for mounting on the struts used in the formwork, whose constitution is much simpler than initially planned, so they have economic advantages and practices with respect to these, also having better ones safety features

In accordance with the present improvements, the fastening hooks for flexible safety elements they consist of a single metallic filar element, for example a thin steel rod that by special bending and finishing specific one end allows its very economical manufacturing and a highly effective use, also presenting remarkable safety features Essentially, the hook is constituted by two sections or straight arms separated by a helical zone in the form of a single spiral or "eyelet" of somewhat open ends, in which the rings of suspension of the protection network, presenting as a characteristic specific that one end of one of said rectilinear elements ends flattened, while the other forms a double hook. The first hook takes the form of an acute angle and the second It takes a substantially right angle shape. Through this constitution enables easy stringing of the ring of the net by one end of the hook staying in the central eyelet and enabling the passage of the double end hook through one of the strut holes, resting on the edge of the hole in the strut by the vertex of the acute angle of the first angle bend, while the second bend of the angled end noticeably straight serves as a security element to prevent fortuitous detachment of the hook with respect to the strut. He flattened end is intended to facilitate the handling of hook with a pole equipped with a groove adaptable to said terminal.

For your better understanding they are attached, by title explanatory example but not limiting, some drawings of a Exemplary embodiment of the present invention.

Figures 1 and 2 are elevation views lateral and plan of the hook object of the present refinements

Figure 3 schematically shows the position relative of the hook with a ring of the protection net.

As shown in the figures, the hook (1) it has two straight arms (2) and (3) separated by an eyelet intermediate (4) constituted by a single spiral, with ends somewhat open, formed by bending the hook material and finishing respectively the arm (2) in the flattened area (5) and the arm (3) in a double hook that constitutes two successive sections, the first of them (6) separated by an acute angle zone (7) and the second zone (8) substantially straight and determined on the one hand bent at right angles (9).

This arrangement allows the hook to be easily incorporate by the end of the arm (3) into the holes of the formwork struts, retaining the bent end in sensitive right angle shape (8) the hook inside said hole, preventing its accidental fall. The ring (10) of a network of protection (11), figure 3, has been previously introduced or later by the end (2) until reaching the eyelet (4) in a mounting arrangement similar to that provided for in the patent principal.

The end (5) will allow the handling of the hook to distance by a pole with a grooved end shaped conjugated to said flattened area (5).

Through these improvements, it achieves, therefore, a great constructive simplicity in the hook object of the main patent, also providing some remarkable security features.

Everything that does not affect, alter, change or modify The essence of the described improvements will be variable to Effects of the present invention.

Claims (3)

1. Refinements in the object of the main patent nº 9900807 for: "Safety guard for floor formwork", characterized by understanding the realization of the hook for fixing the protection net on the formwork struts, by means of a single steel rod which has two straight arms connected to each other by means of a circular eyelet made in the rod itself, finishing one of said arms in a flattened area and finishing the other arm in an extreme area that presents two successive hooks, the first one for its retention in the edge of the hole of the right foot and the second of security, preventing its accidental detachment. 2. Refinements in the object of the main patent nº 9900807 for: "Safety guard for floor formwork", according to claim 1, characterized in that the eyelet made between both straight arms consists of a single loop, its ends being somewhat separated for allow the entry of the network suspension ring. 3. Refinements in the object of the main patent No. 9900807 for: "Safety guard for floor formwork", according to claim 1, characterized in that the double hook finish of the end of the other straight arm comprises a first area at an acute angle that it limits a straight section and a second zone at a substantially straight angle that limits a section of shorter length for safety retention.
