Description

DESCRIPTION

Security shield encodable by magnetic pins for door locks.

Object of the invention

The present invention refers to a security shield that can be encoded by magnetic pins to be placed on the cylinder of a conventional lock. In this way, access to the aforementioned cylinder is protected by the interposition of a metal piece that completely conceals it, on the outside of the door.

The codifiable security shield completely hides the cylinder of the conventional lock and, to allow its opening, it is necessary to enter an access code, when entering the code a protection cover is unlocked, allowing it to rotate on itself (180 °) so that an opening in it is aligned with the cylinder in the lock.

To activate the opening code, it is necessary to extract the pins that contain the password to the outermost position of the pins. The rest of the pins (those that do not contain the password) must be pressed, in the innermost position of the pins.

The encodable security shield allows it to be used in any position (horizontal vertical, inclined etc.) since the pins have a magnet that adheres to an anti-detection plate which has dimensions and suitable material, therefore, the pins have freedom of longitudinal movement, but they remain attached by the action of the magnet in all their positions, which includes the extreme positions (maximum extension, minimum extension). The user can overcome the action of the magnet, since it has limited strength and is only used as a positioning element.

The codifiable security shield is applicable to the protection of the cylinder of door locks, such as cylinders intended to be installed on doors of houses or other types of residences, including industrial installations. Although the invention could be applicable to any type of lock that allows its opening with the use of a key.

The code of the security shield can be changed by the owner whenever it is deemed appropriate. The code change is made by rotating the pins 180 ° along its longitudinal axis.

Technical sector

As is known, the vulnerability of a key-operated lock depends fundamentally on the exposure of the cylinder to vandal manipulation, either with the use of force, or with the use of other more sophisticated techniques.

Likewise, in certain industrial facilities (wind turbines, electrical substations, etc.), in collective facilities (fire stations, hospitals, gas stations, etc.) and even in some domestic ones (hotels, residences, storage rooms, etc.), there is the problem that a A large number of people have the key that gives access to the facilities (maintenance personnel, cleaning services, customers, etc.), which facilitates the vulnerability of the facility.

Therefore, the present invention provides the market with a codable security shield that greatly improves the security of the conventional lock installed on the door, also allowing for easy mounting.

Background of the Invention

There are security shields on the market to be superimposed on the cylinder of a lock, although their technical basis is different.

References to previous applications are listed below:

• Magnetically actuated overlapping safety shield.

• Overlapping safety shield with electronic drive.

• Override safety shield with key actuation.

Description of the Invention

The encodable security shield that is recommended has been conceived to solve the problems previously exposed:

First: the codifiable security shield does not require modifications to the door or the lock to allow its installation, since it is a piece that overlaps the existing cylinder in the lock. The codable security shield is installed on the outside of the door and bolts in from the inside of the door.

Second: the encodable security shield does not require any type of external power source, its operation is purely mechanical and magnetic.

Third: the encodable security shield provides security to the lock cylinder, it has a protection cover that completely conceals the cylinder, by interposition of the mentioned protection cover, the opening of this protection cover is allowed after the inclusion of a numeric code. The metal lid is unlocked by turning it 180 ° along its longitudinal axis, that is, curved movement with circular geometry, once the access code has been entered.

Fourth: to unlock the encodable security shield, it is necessary to extract the pins that provide the opening to the maximum extraction position, with the pins that provide the closure being inserted (in the minimum extraction position).

Fifth: the access code that allows the unlocking of the protection cover placed in front of the cylinder can be changed when deemed convenient and the number of digits provided by the opening can also be changed when deemed appropriate, to make the change it is necessary remove the door shield and rotate the pins 180 ° (as the user deems appropriate) along its longitudinal axis.

Sixth: the change in the access code is made by turning the pieces called pins (180 ° along its longitudinal axis). These position-mounted pins provide opening of the shield when removed, and mounted in the opposite position provide closure of the shield when withdrawn. Therefore, for the shield to be released, only the pins that are mounted in the opening direction must be removed.

Seventh: The encodable security shield has an internal mechanism that prevents the code that provides the opening from being identified. This is achieved through two systems:

• The adjustment of the pins in relation to the hole that contains them in the protection conical shell provides a dimensional adjustment, which prevents vandalism of the shield from allowing the unlock code to be identified.

• The pins have a magnet on the back (the pin and the magnet form a single body), these magnets adhere to an anti-detection plate, which has adequate dimensions and material, when one of the pins moves in any direction Other than longitudinal, the rest of the pins also move since they are all attached to the same anti-detection plate through which the movement is transmitted.

Eighth: the codable security shield allows it to be used in any position (horizontal vertical, inclined etc.) since the pins have a magnet that adheres to a plate which has adequate dimensions and material, therefore, the pins have freedom of longitudinal movement, but they remain attached by the action of the magnet in all their positions, which includes the extreme positions (maximum extraction, minimum extraction). The user can overcome the action of the magnet, since it has limited strength and is only used as a positioning element.

These features of the codeable security shield for locks provide a series of improvements that previous models did not provide:

■ No energy source (neither internal nor external) is necessary for its operation, since it is a purely mechanical and magnetic system.

■ The code that allows the unlockable security code for the locks to be unlocked can be changed when necessary.

■ The number of digits that provide the opening of the codeable security shield for locks can be changed when necessary.

■ The encodable security shield has an internal system that prevents the opening code from being identified.

■ The codifiable security shield for locks provides great resistance to vandalism, since all the parts that make up the security shield remain inside a fixed piece called the frusto-conical protection shell, which has a frusto-conical shape that prevents tampering vandalism.

■ The codifiable security shield allows it to be used in any position (horizontal vertical, inclined etc.) since the pins have a magnet that adheres to a plate which has adequate dimensions and material.

■ The unlock code is entered by removing the pins that provide the opening (up to the maximum extraction position), leaving the pins that provide the closing (in the minimum extraction position).

Brief description of the drawings

To complement the description that will be made below and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical embodiment thereof, a set of drawings is included as an integral part of said description. where, by way of illustration and not limitation, the following has been represented:

Figure 1: represents an overview of the encodable security shield, as well as an exploded view of the invention in which all the essential mechanisms of the encodable security shield are listed:

■ No. 1 frusto-conical protection shell.

■ N ° 2 protection cover.

■ N ° 3 locking or unlocking pin with magnet n ° 4.

■ No. 4 magnet.

■ N ° 5 anti-detection plate.

Figure 2: Represents the codable security shield in the closed position, and in this case the two pins that provide the unlock password extracted the lock cylinder is hidden behind the protection cover (No. 2), the opening of the Security shield is made (once the pins that provide the unlock code have been removed) by rotating the protection cover (n ° 2) 180 ° along its longitudinal axis. In this way, the opening in the protection cover aligns with the lock cylinder and allows insertion of the cylinder key.

Figure 3: Represents a sectional view of the encodable security shield, in which the opening and closing action of the pins (n ° 3) is indicated, as seen from the top pin (n ° 3), when it is removed. longitudinally, it provides opening of the protection cover (n ° 2), however, the lower pin (n ° 3) when it is extracted longitudinally provides blocking of the protection cover (n ° 2).

Figure 4: Represents in detail how the pins (n ° 3) provide opening or locking to the protection cover (n ° 2), depending on whether they are placed in one position or in the opposite 180 °. In the left image it is seen how the upper pin (n ° 3) and the lower pin (n ° 3) are inserted, in this case the protection cap (n ° 2) is blocked by the action of the upper pin (n ° 3 ) and cannot rotate 180 ° around its longitudinal axis to allow opening. In the right image it is seen how the upper pin (n ° 3) is extracted longitudinally, in this case the protection cover (n ° 2) is unlocked by the action of both upper pins (n ° 3) and can rotate 180 ° around its longitudinal axis to allow opening. In this way the desired combination is achieved for unlocking the encodable security shield.

Figure 5: Represents a sectional view of the encodable security shield, in this view it can be seen how the magnets (n ° 4) located at the rear of the pins (n ° 3) are in contact and adhered by the action of the magnetic effect to the anti-detection plate (# 5), this configuration provides:

■ The pins (n ° 3) maintain their position of both maximum extraction and minimum extraction and have freedom of longitudinal movement, this allows the encodable security shield to be used in any position (vertical horizontal, inclined etc.).

■ The anti-detection plate (n ° 5) is allowed to circulate around the body of the encodable security shield and associated with it by the action of the magnets (n ° 4) are the pins (n ° 3). movement (in any direction other than longitudinal) in one of the pins (n ° 3) is transferred to the rest of them through the aforementioned anti-detection plate, this effect makes it impossible to fraudulently detect the opening code.

Figure 6: Represents a view of the anti-detection system individually, in the anti-detection system the pins (n ° 3) that lodge in the anti-detection plate (n ° 5) intervene and are adhered to it by the magnetic action of the magnets (n ° 4), as indicated above, with this it is achieved that a movement (in any direction other than the longitudinal one) in one of the pins (n ° 3) is transferred to the rest of them through the aforementioned anti-detection plate, this effect makes fraudulent detection of the opening code impossible.

Figure 7: Represents a detailed view of the clearance between the pins (No. 3) and their circular accommodation in the frusto-conical shell (No. 1). The adjustment of the pins, in relation to the hole that contains them in the protection conical shell, has an adequate dimensional adjustment, which prevents the vandalism manipulation of the shield allowing the identification of the unlock code. This is because the fit between the pin and the hole that houses it is dimensionally small and does not allow movements other than longitudinal movement.

PREFERRED EMBODIMENT OF THE INVENTION

Considering the numbering adopted in the figures, it has been foreseen that the codable security shield has ten buttons for the selection of the code, although the invention could be presented with other configurations without affecting the essence of the invention.

Likewise, in the preferred embodiment of the invention, the integration of the opening and closing of the encodable security lock has been chosen by using a single geometry for the pin (No. 3), which acts as an opening if it is placed in one position and acts as a closure if placed in the opposite position (rotated 180 ° around its longitudinal axis) the separation of this single pin into two different pins would not affect the essence of the invention.

Well, according to Figures 1 to 7, the encodable security shield, preferably metallic in nature, incorporates a system for blocking one of its parts, protection cover (No. 2), by means of the action of pins. (# 3) With proper geometry, the pins (# 3) can be placed (inserted into the codable security shield) in two positions, at the user's choice.

■ If the initial position of the pin (n ° 3) is open, when we act on it (longitudinal displacement of extraction) it will go to the closed position, preventing the opening of the encodable security lock.

■ If the initial position of the pin (n ° 3) is closed, when we act on it (longitudinal displacement of extraction) it will go to the open position, allowing the encodable security lock to open.

■ The combination of these two pin positions (n ° 3) is what gives the codable security shield its coding capacity, also allowing the code change, as well as the change in the number of digits that provide the opening of the codifiable security shield, all this according to the needs of the user.

To activate the opening code, it is necessary to extract the pins (n ° 3) that contain the password to the outermost position of the pins. The rest of the pins (n ° 3) (those that do not contain the password) must be pressed, in the innermost position of them. Entering the code unlocks the protection cover (n ° 2), which allows it to rotate around itself, 180 ° around its longitudinal axis, so that an opening present in it is aligned with the existing cylinder in the lock allowing the insertion of the cylinder key.

The codifiable security shield allows it to be used in any position (horizontal vertical, inclined etc.) since the pins (n ° 3) have a magnet (n ° 4) that adheres to an anti-detection plate (n ° 5). which has dimensions and suitable material, therefore, the pins (n ° 3) have freedom of longitudinal movement (when the user overcomes the magnetic force of the magnet (n ° 4)), but they remain adhered by the action of the magnet (n ° 4) in all its positions, which includes the extreme positions (maximum extension, minimum extension).

Furthermore, in the preferred embodiment of the invention, the inclusion of a system that fraudulently prevents the identification of the unlock code (by manipulation of the security shield systems exposed to the outside) has been chosen. This is achieved through two systems:

■ The adjustment of the pins (n ° 3) in relation to the hole that contains them in the frusto-conical protection shell (n ° 1) provides a suitable dimensional adjustment, which prevents vandalism of the shield from allowing the identification of the unlock code. .

■ The pins (n ° 3) have a magnet (n ° 4) on their back, these magnets adhere to an anti-detection plate (n ° 5) which has dimensions and suitable material, when one of the pins (n ° 3) moves in any direction other than longitudinal, the rest of the pins also move since they are all attached to the same anti-detection plate through which the movement is transmitted.
