Description

DESCRIPTION

Security device with hidden lock.

Sector of the technique to which the invention refers

The invention presented affects the Fixed Constructions Sector. section of Buildings regarding Locks, Keys, Accessories for doors or windows affecting, from the industrial point of view, in the manufacture of locks and security devices for doors of public buildings, offices or private homes and in their corresponding chains of distribution. BACKGROUND OF THE INVENTION

Bearing in mind that in modern life it is considered a priority to safeguard the existing assets in public or private homes or premises with maximum security, it is understood that there are many solutions regarding locks applicable to doors or windows. The complexity of the locks has been increasing progressively from the old locks of enormous keys and locks to the most modern of electronic type that are opened by applying a code on an external keyboard or even acting on a remote control.

As for the bulbs and llavin type, widespread throughout the world, models have been developed that affect the special toothing or milling of the keyholes or incorporate a magnetic element on the key itself.

More recently, closure and security devices are built based on the recognition of fingerprints or the pupil of the eyes.

Finally we can indicate that the attention of the inventors has also focused on the automotive market developing very advanced solutions considering that the opening of its doors can not only lead to the theft of content but can end with the theft of the car itself . The most widespread solution is the remote opening of the doors of the cars with the possibility of opening with a key in the event of failure of the power batteries or any other.

This solution, applied profusely to automobiles, begins to be used for the opening of doors of private homes when the user verifies that the alternative of installing several conventional locks on the same door does not solve the problem. Indeed friends of others have developed techniques for opening any type of lock and although placing several locks makes possible the possible actions of theft, it is not a decisive solution.

That is the reason for leaning for the installation of so-called hidden locks that have the advantage of not being detected from the outside, so in the extreme case that the person trying to enter manages to open or force the closing points detectable from the outside, you will encounter an added and unexpected difficulty that will force you to desist.

That is the reason that has prompted the inventor to design the invention presented in this document, which, being simple, is very suitable for reinforcing security in private homes, offices or any type of premises. Description of the invention

The invention described in this document refers to a hidden lock, applicable to any type of door, which has the particularity of managing its opening by means of a remote control.

It is a lock that complements others that are already installed in the same door. It is generally known that there is a method (known as bumping), practiced by specialized thieves, with which you can open most of the locks without a trace which has serious inconveniences not only for the consequences of the theft but because the insurance companies do not give credibility to the person who reports it.

On the basis of this background, the inventor proposes a lock solution in the form of a folding leg electrically operated by radio which, in the open position, is folded over the door and in the closed position, is positioned as a strut whose end is inserted into the floor, on the ceiling, or on one of the walls adjacent to the door.

It can be powered by rechargeable batteries or directly from the network before transforming and rectifying the voltage so it is always available except in the case of mechanical failures that, for any reason, prevent its normal operation. In this case, the inventor contemplates an emergency solution that allows opening in the most unfavorable case that occurs when the closed door situation occurs and the user leaves the home. It is a module of small size and easy installation by anyone who has the usual means and classic tools. The collapsible leg is, in the basic model, of a length of the order of 15-20 centimeters and is designed to accept supplements in case that greater lengths are required depending on the situation of the door in relation to the propping surface. The leg is divided into two parts, equipped with separate sections of female thread, joined by a threaded stud that allows in all cases fine adjustments so that the appendix fits perfectly in the hole made in the ground. This arrangement also makes it possible to replace one section with another of different length in order to apply the solution of the invention in all cases that may arise.

The solution is simpler and much more economical than others that can be considered similar, such as armored doors with multiple locks at various points in the door frame. The schematic figures, which are included in the following section, forming an inseparable complement of this document, make it easy to understand the basis of the document and its practical possibilities.

Security device with hidden lock (Figs 1 to 7) consisting of a hidden lock, applicable to any type of door, which, complementing others already installed in the same door, has the particularity of managing its opening by means of a remote control. In a preferred embodiment by its inventor, it is a small folding strut driven by radio waves that is installed, in principle, in the lower part of a door (1) complementing the main lock (2). In the open position, it is folded over the door (1) and in the closed position, it is positioned in such a way that the appendix (7), which has its free end, is inserted in the floor (12) where it has been practiced a hole (13) which is then protected with a trim ring (14) serving as a stop for a closing plate (15) under which a spring (16) is placed. In this closed position, as shown in (Figs 3 and 4), the appendix (7) is inserted into the hole (13), making it descend to the closing plate (15) that presses on the spring (16) . On the other hand, in the open position (Figs 1 and 2) the spring (16) keeps said closing plate (15) in an elevated position, protecting the hole (13) against the entry of dirt or foreign bodies. As for the small strut mentioned, it consists of a permanent section (3), inseparable from the rest of the device, and a replaceable section (4) which, as the name suggests, can be replaced by others of different lengths depending on the needs raised (distance to the ceiling, to the wall or fixed point chosen). The permanent (3) and replaceable (4) sections, both with female thread, are joined by means of a threaded stud (5) and immobilized by means of nuts (6).

This arrangement also allows to make small adjustments so that the appendix (7) penetrates without difficulty in the hole (13). For practical purposes you can choose to use modular capsules, those existing in the market, grouping the trim (14), the closing plate (15) and the spring (16).

The strut, name with which, for simplicity, we name the set of the permanent section (3), replaceable section (4), threaded stud (5) and nuts (6), rotates on a horizontal axis that is held firmly on the door (1) through supports (8) duly screwed.

The mechanism that governs the upward and downward movement of the strut, is inside a housing (9), including a motor (17) of direct current and maximum voltage of 12 volts powered by a rechargeable battery (19).

Between the power output shaft of the motor (17) and the axis of the strut, a reduction group (18) is inserted with a series of gears, the movement of the strut being limited by two limit switches (21) defining the open positions. and closed.

Inside the casing (9) there is also installed a controller receiver (20) which receives, by means of an antenna (10), the radio waves emitted from the outside of the door (1) when the person (22), who wants open, acts on the remote control (23) as outlined in (Fig.7). All the elements mentioned are represented in (Figs 1 to 7).

In (Figs 1 and 2) the device is in the open position with the strut raised and stuck to the door (1). Note that the spring (16) is distended maintaining in the highest position the closing plate (15). If the main lock (2) is open, there is no inconvenience to open the door (1).

In (Figs 3 and 4) the device is in the closed position with the strut lowered and its appendix (7) inserted in the hole (13) causing the closing plate (15) to compress the spring (16). ). In that case, even if the main lock (2) is open, the door (1) can not be opened.

In the (Figs 5 and 6) extended views of the device are shown, without housing, (Fig.5) or with housing part (9) (Fig. 6 being able to appreciate the position of the limit switches (21) and also the start of the channel (11) that houses the wiring from the rectifier transformer group (24).

The device is permanently powered from the network before transforming its voltage to 12 volts DC by transformer and diode bridge rectifier with smoothing coils. In the event of a mains voltage failure, the motor (17) is supplied from the rechargeable battery (19) whose charge state is continuously regulated from the controller receiver board (20) which also receives information from the limit switches. (twenty-one).

There may be an emergency case in which the mechanism remains immobilized for any reason or the person (22) has lost the remote control (23). If this situation occurs, the inventor has foreseen that when the installation is carried out, the Cartesian coordinates, abscissa and ordinate, of a point of the door where, practicing a small drill (2-3 mm) from the outside, will be determined with exactitude. , you can introduce a rod that pushes and lift the strut. The device can be placed, according to convenience, for closing on the floor, as it is explained in the previous description, or closing on the roof, for which the use of several struts of struts is foreseen replacing the replaceable section (4).

It is not considered necessary to broaden the content of this description so that an expert in the field can understand its scope and the advantages derived from the invention, as well as develop and carry out the object of the invention. However, it should be understood that the invention has been described according to a preferred embodiment thereof, so that it may be susceptible to modifications, being able to affect such modifications to the shape, size and / or materials of manufacture without it having an impact or suppose any alteration of the foundation of said invention. That is, the terms in which this preferred description of the invention has been exposed, should always be taken in a broad and non-limiting manner.
