Description

Hardware for security lock.

Object of the invention

The object of the present invention is a hardware which allows you to convert a built-in lock in no time conventional in a hard-to-open security lock for children.

Background of the invention

The problem that children present is known of a certain age that, once they acquire mobility by themselves, they tend to explore the entire area they are in, reaching sometimes dangerous situations occur if an adult does not watch them constantly. To prevent children from entering certain closed rooms or enclosures, some solutions are known. By example, below a certain height the children do not reach the knobs or door latches, so it is enough to close the door. However, once they reach that height, it is done It is necessary to use locked doors to prevent its passage. This It is cumbersome, since before a locked door also Any adult who wishes to pass must ask for such keys to the adult That closed the door.

An example of these situations occurs in public swimming pools, where it is not permissible to interpose a door locked to the entrance of the facility or to access the pool.

Description

The present invention describes a hardware for conventional inlay locks comprising:

one)

A hollow box of a suitable size to insert into the profile of a door and to house a lock embedded in its inside. In this document it is called "side face" a the face left in the door frame, through which you must pass the slip and, where appropriate, the metal bar that It allows the door to be locked. On the other hand, it is called "front face" to the face on which the bowler of the lock.

So, the box it has, in its lateral face, a hollow of a suitable size for allow assembly and disassembly of the embedded lock. The lock is thus fixed to the door frame by screws or similar, leaving the entire mechanism inside the box of the hardware of the invention. On the other hand, the front face of the box It comprises two holes: first, a race below through which the lock cylinder looms from the front of the door, allowing this lower race relative movement vertical of the inlay lock cylinder; second, a upper hole formed by a rectangular portion, which prevents the turn of the inlay lock square, and a portion widened allowing rotation of the lock square stuffed The widened portion is preferably shaped circular.

2)

A spring arranged inside the box in such a way that, leaning on the inlay lock, force the box into a position where the square of the embedded lock is inside of the rectangular portion of the upper hole, so that it prevents its turn. Although in a preferred embodiment the spring is arranged inside the lower end of the box, it is you can have any other way as long as you meet that function. For example, it could be at the upper end.

3)

Some opening means that allow moving the box in the direction opposite to the force exerted by the spring, so that the square of the inlay lock is inside the portion widened from the upper hole, so that its turn.

Brief description of the drawings

Fig. 1 shows a perspective view of a conventional lock fixed to a door.

Fig. 2 shows a perspective view of a hardware in accordance with the present invention.

Figs. 3a and 3b show paths seen front of the hardware of the invention installed in a lock, respectively in locked position and in position of opening.

Preferred Embodiment of the Invention

An embodiment is described below. particular of the present invention with specific reference to The attached figures. In particular, Fig. 1 shows a view in perspective of a conventional lock (100), fixed by screws to a door (200). You can see how it stands out on its side lateral the slip (103) and the metal bar (104), while in its front side are the square (102), to which it is fixed the doorknob or door knob, and the bowler (101) that receives the key to move the metal bar (104).

On the other hand, Fig. 2 shows a hardware (1) according to the present invention, which comprises the box (2), the spring (6) and the opening means (7). The lateral face (2L) of box has a hole (3) that allows the passage of the body of a lock (100), while the front face (2F) comprises two holes: a bottom race (4) a top hole (5). The lower race (4) is wide enough to allow passage of the cylinder (101) of the lock (200) and extends vertically to allow relative vertical movement of the lock (200) in relation to the box (2). The upper hole (5) has two parts: the rectangular portion (5R) has a width equal to that of the square (102) of the lock (200), so that it prevents rotation of the square (102), while the widened portion (5E), in that case of circular form, is wider to allow the rotation of the square (102).

The spring (6) can also be seen in Fig. 2, arranged at the lower end of the box (2), and the means of opening (7), which in this example consist of a ball.

Thus, the hardware (1) of the invention is used as follows. First, to install it, simply disassemble the conventional door lock (100), being introduced from the hardware (1) through an upper hole. Then it goes back to insert the lock (100), leaving the square (102) and the cylinder (101) respectively inside the upper hole (5R) and of the lower race (4). Then the lock (100) is fixed to the Door frame (200) using the corresponding screws. The lock (100) is thus fixed to the door (200), while the box (2) can move vertically, being in principle in its closing or lower position, since the spring (6) is supported by the lock (100) to push the box (2) down. In this closed position, the square (102) is in the portion rectangular (5R) of the top hole (5), so that it is not possible to turn it to open the door (200). For this, it is necessary for a person to pull vertically up the means of opening (7) until the force exerted by the spring (6) is exceeded. From this way, the vertical displacement of the box (2) is achieved, leaving the square in the widened portion (5R) of the hole top (5), which allows the door to open.
