Description

"IMPROVEMENTS INTRODUCED IN UNIVERSAL CLOSURE".

TECHNICAL FIELD

It is the present invention of the universal lock assembly improvements, more precisely, it is a universal lock configured by a set of individually interconnectable elements, especially made of rigid polymer which allows quick and easy assembly of the individual elements by setting a simplified lock. It is effective for installation in office, home, school, glass doors and windows, motorcycle trunks, among other products requiring protection.

TECHNICAL BACKGROUNDS

As is well known, with increasing burglary and petty theft in homes, businesses, schools, gyms, hostels, etc. Most citizens seek to protect their belongings by installing hardware such as fixed or movable locks for locking cabinets, furniture drawers, doors and windows, among others.

Said movable locks, also known as padlocks, are generally configured by a locking mechanism operated locking mechanism for the release or locking of a hook which, in turn, is mounted in holes provided in pairs of projecting wings developed from of the outer surface of furniture, doors, windows, etc. Despite the said padlocks have great effectiveness against break-in and ease during installation, as they do not require the use of hardware and screws, the configuration of the structural body of conventional padlocks make it impossible to install anywhere, because the same You need tabs, tabs, or other suitable means for hook mounting.

Thus, the hardware industry continuously develops various models of lock for installation in furniture, doors, windows, cabinets that allow the protection of environments and objects, and currently there are various models of lock, such as the recessed lock model, which is equipped with a backrest latch operated by the handle, said recessed lock being installed inside doors and windows.

The main drawback of said locking model is that many doors and / or windows are not thick enough to accommodate them, especially the thickness of the furniture, such as cabinets, cabinets, drawers, among others that make it impossible to install the lock.

To this end, there are conventional and simplified universal locks on the market which are configured by a tubular part whose outer surface may be threaded, while the inner portion has the locking core whose free end receives a locking tongue.

The drawback of this universal locking model is that most conventional models are made of chrome-plated steel allowing for an increase in the value of the product.

A brief survey of patent banks allowed us to know a Brazilian lock model, no. PI0104311-0 dealing with a lock for locking windows and sliding gates of a kind constructed from aluminum frames or mullions, the core of which is filled with glass plates or metal plates; said lock is preferably actuated by the key tetra and comprises a metal case and a through-hole mirror; said housing serves as housing for the tongue drive components consisting of a secret drum and a drag rack system made of movable teeth or pins; another mirror with corresponding through hole which is provided to be fixed in the locking stop cavity of said tongue; Said lock provides that on at least two faces of the locking tongue, pairs of individual pivoting tilt stem parts are arranged, each of which has a gripping element which can actuate when the tongue is passed through the holes and the mirrors and locking the tongue. door or window casement of the jamb.

The main drawback of such a document is that the locking tab is configured by pairs of tilting stem parts, which are mounted individual prongs that can promote wear or tear during frequent movement of the stem parts and, consequently, the lock being unusable.BREVE OBJECT DESCRIPTION

After carefully analyzing the state of the art, the applicant has developed a universal lock configured by a set of individual and interconnectable elements, especially made of rigid polymer allowing quick and practical assembly of the individual elements configuring a simplified and effective lock for installation in office, residential furniture. , school, doors and glass windows, motorcycle cases, among other products that need protection.

Said innovative universal lock assembly is basically configured by a coupling conditioner and coupling receptacle, said receptacle having a limiting cavity, which is aligned with a central opening practiced in the lower portion of said conditioner receptacle, while said limiting cavity is provided with a limiting cavity. a pinoguery pair of a locking tongue pair which are interconnected by means of a spring which provides for continuous spacing of the locking ends of said locking tongue.

Said conditioner receptacle further comprises crimping means of a closure cap, which comprises a tubular sleeve for housing a cylinder actuator of said locking tongues, said locking cylinder being mounted at the end of the locking drum.

Said coupling stop is configured by an individual plate where a central cut-out is practiced which, in turn, is flanked by through holes for the coupling of screws.

OBJECTIVES AND ADVANTAGES The main advantage of this universal lock set lies in the fact that it presents simplicity in the assembly of the elements that make up the lock, as this assembly is basically developed through pins and projections providing greater productive agility and considerable reduction in cost.

Another advantage lies in the fact that the parts that make up the universal lock are made of rigid polymer providing lightness of the set.
