Description

[001] This Utility Model patent describes, for use in the residential, commercial and industrial civil construction sector, a system for limiting the opening of a maximum-air type casement window, whether made of aluminum, iron, PVC, wood, tempered glass, or any other material, which innovates by bringing a design, functionality and form of application different from any of the systems currently existing on the market. [002] This technological solution makes it possible to increase the security of the building by allowing the opening of the tilting window to be limited, according to the needs of the demand, as well as according to the requirements of the environment, solving the security problem registered in the present day. [003] It is known that the tilt-and-turn window is currently incorporated into industrial, commercial and residential buildings without restriction, adopted globally beyond its architectural form. The locks for these types of windows, in the state of the art, do not offer security or flexibility for limiting the opening according to the user's needs and the various conditions of the surroundings, demonstrating the precariousness of the use of this type of equipment. [004] The utility model described in this patent aims to offer the market a lever-type lock that brings with it a new device, a new option for limiting the opening of a tilting window, in an efficient, safe, durable and economical way. [005] The present utility model corresponds to a functional improvement of patent applications BR102021004946-4 which presents a “DEVICE FOR CLOSING AND OPENING A WINDOW” and application BR102023004598-7 “in secrecy”, which presents a “ROD FOR ADJUSTING AND LOCKING THE OPENING OF A TILTING WINDOW”, authored by the same inventor. [006] Searches conducted in major patent databases revealed some similar technologies, which do not offer efficient solutions compared to those described in this Utility Model patent. [007] Patent BR 202015031796-0 presents a square-locking latch for sliding windows. This latch consists of two mirrored counterparts that engage with each other by a short angular movement lock. [008] Patent BR 202015031794-3 presents a latch with a central safety pin for windows, to internally lock pivoting windows that use a central expansion pin inserted in the center of the pivot axis of the tilting latch that prevents it from coming loose under random force conditions. [009] Patent BR 202018006721-0 presents a recessed swing lock and retractable counter-lock for sliding doors and windows. This system consists of providing a simplified, manually operated locking mechanism, allowing its installation within the profile of the window's movable sash frame itself. [010] Patent Pl0702566-1 presents an improvement introduced in a lever-type latch installed in windows, doors and tilting elements, which consists of a base fixed to the inner face of a frame, this face being positioned parallel to a fixed closing flap. [011] Patent PI 9603637-0 presents a hinged latch mounted on a universal joint with the function of limiting and closing windows. This latch comprises a polyamide fixing base, which has at one of its ends a sphere that will couple to two concave pieces forming said universal joint. The system has an aluminum tube that functions as a lever in closing the assembly and as an opening limiter. [012] Patent MU8301095-5 presents constructive arrangements made in a rod-lock designed to be coupled to a casement window. This system has a rod that passes through a lock, in which this rod is fixed to the casement window sash and the rod is used to open and close the casement window's rotation movement. This rod also allows the window to be locked by rotating the rod and fitting it into the locking system. [013] Patent MU8802720-1 presents a constructive arrangement applied to an articulated rod with remote actuation for windows. This system consists of a sliding articulated fastener on a rail fixed to the face of the window, which is pushed by the movement of the telescopic articulated rod that covers a long opening span after being activated, and has a locking pin to act with the safety lock and pressure when returning to the initial position, the same being actuated by a threaded shaft connected to the safety lock motor. [014] Patent MU 8602052-8 presents constructive arrangements introduced in doors and windows, which are now equipped with a security means consisting of a lock whose activation moves two rods in a transverse and opposite direction, developed in order to lock onto opposite vertical jambs, providing total resistance against any attempts at forced entry. [015] Patent MU 8102306-5 presents a lock for sliding windows, whose central lock has two male and female fittings, to be fixed to each of the uprights of the inner sliding window sashes, one of these seats being static and the other articulated by springs. The assembly is completed by side locks for intermediate sliding sash
