Description

Security device for locks doors.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a device of security for door locks whose purpose is strengthen the security of doors by not allowing to perform lever in the lock or prevent the passage of any element that can act on the latch to open the door forced form.

Background of the invention

There are currently devices for security for doors, which include those that they consist of a pair of profiles of different sections mounted to the along the entire height of the door on the side where it is arranged the lock.

Optionally, two other profiles can be mounted on the side where the door hinges are arranged. This safety device avoids levering directly on the area of the lock and the entire length of the door, in addition to prevent the introduction of any element to act directly on the door latch and open it.

The device in question consists of two profiles, one that has an "L" shape and is mounted on the frame or fixed part of the frame, while the second profile It has a U-shaped section and is mounted on the door. Other characteristic of this device is that, although it is exterior and accessible to anyone it is impossible to disassemble it, since obviously with the door closed you cannot access the screws that hold both profiles.

The only disadvantages we could cite about this device would be the aesthetic to be seen and its assembly that must be very precise to get both profiles fit perfectly with each other, allowing the door to close and on the other hand eliminating any space between both profiles that could allow the passage of an element to act on the door latch.

Description of the invention

The safety device for locks doors constituting the object of the invention is characterized because it is determined from a groove located in an extension front of the frame or fixed side of the door where the same when closed, grooved that is complemented by an element male solidarity of the door, well forming an integral part of the same, well determined by an independent element set to said door by any means.

These two complementary elements male and female (grooved) are at least ready of the latch and closing bolts, there being the possibility of be located in all or part of the total height of the door.

This new security system is not visible when the door is closed, so it doesn't break the aesthetics of the same.

Preferably the male element will be located in the door while the grooving where said is introduced profile or male element will be located in the frame or part fixed door frame where it stops but when We talk about a door with a fixed side. This provision may be inverted, the profile or male element being located in the part fixed, that is, on the frame or fixed part of the frame while that the slot will be in the door.

As we have already mentioned, the device security can be mounted at the height of the lock disabling any action on the latch and lever on the same, or, may be arranged along the entire height of the door avoiding being able to leverage at any point.

The male element preferably located in the door may be a constitutive part of the door, that is, form an integral part of the door obtaining in the manufacture of the same or, it may be a supplementary piece to be fastened to the door by screwing on wooden doors or by soldier in iron doors. These male elements may have different configurations

The male elements will preferably be of iron or steel, although it is not ruled out that they may be from others materials that have the right characteristics for their utilization, mainly according to its hardness.

Next to facilitate a better understanding of this descriptive report and being an integral part of the same accompany some figures in which with character illustrative and not limiting the object of the invention.

Brief description of the drawings

Figure 1.- Shows a plan view of the safety device for door locks, object of the invention.

Figure 2.- Shows a sectional view of the safety device of the invention.

Figure 3.- Shows a sectional view according to the section A-A 'of figure 1.

Figures 4 and 5.- They show respective views in plant a part of the device of the invention.

Description of the preferred embodiment

Considering the numbering adopted in the figures, the security device for door locks is determined from a front extension 1 that starts from the frame or fixed side 2 of a door 3 and on which it stops the door when it closes, so that said extension front 1 has a vertical grooving 4 where it fits in addition a male element 5 integral to the face outside door 3 when it closes.

These two complementary elements 4 and 5 are located at least at the height of the lock bolt 6 and latch 7, although they could occupy a greater length.

In addition, these two elements 4 and 5 avoid any attempt to force door 3 with a lever, since the access to latch area 7 and lock bolt 6 is hidden and inaccessible when door 3 is in position closed.

In a preferred embodiment shown in the Figure 4, the male element consists of an angular profile 5 'by a  whose wings are fixed to the outer face of door 3 by screws 8.

In another preferred embodiment shown in the Figure 5, the male element consists of a 5 '' profile with two extreme couplings that can be fixed to the edge of door 3 through which latch 7 and bolt 6 appears, being able to also fix on the front face of said door 3.
