Abstract

The invention relates to a mechanically-actuating automatic lock, wherein the bolt or bolts are inserted into the door frame when the door is closed without requiring the use of a key. The door can be locked with the aid of a special configuration of springs, rocker arms and release mechanisms, such that the bolts are automatically housed in the frame without the use of a key. Similarly, the door can be unlocked simply by pushing a button or a handle or rotating the key. The inventive automatic lock can also be remotely controlled.

Description

AUTOMATIC LOCK

DESCRIPTION

OBJECT OF THE INVENTION

The present invention consists of an automatic mechanical actuation lock so that when the door is closed, it remains with the pin or the pins inserted in the frame without the use of the key.

A special configuration of springs, rockers and triggers allows the door to be locked and therefore the housing of the pins in the frame automatically without the use of the key; and in the opening, its unlocking without pressing a button, handle or simple turn on the key.

BACKGROUND OF THE INVENTION

Automatic locks seek opening or closing without requiring the manual use of the key. This does not mean that the key cannot or should be used in one of such operations or that it is an additional opening means for security reasons.

These locks can make use of electromagnetic actuators or electrically powered motors.

The disadvantage of this type of locks is that they depend on the uninterrupted availability of the power supply so it is necessary that they be designed in such a way that in case of power failure they continue to ensure the closure but in turn their manual opening

In response to these types of problems, a fully mechanical automatic lock is protected by the patent with publication number WO2070844.

In this lock, various springs are used that drive the latch or the pin for closing, taking advantage of the energy that is provided when the door is pushed and closed.

During the closing, the inclined plane of the latch which ensures that it retracts when making contact with the edge of the door strike pushes the entrance of this latch. This impulse is what serves to tighten various springs that will allow the movements of the latch or the pin for closing or recovery.

In the aforementioned Patent, the operation depends on both the elements introduced in the lock and those introduced in the lock within the frame of the door. The presence of a rocker allows the movement of the pin to be communicated with that of the latch to complete the set of possible positions both at the opening and at the closing.

The present invention establishes a new configuration based on the principle of storage of potential energy in various springs where all the mechanisms, those of actuation and closure such as those of recovery, are entirely in the lock box located on the door leaf , - and, allow remote action. DESCRIPTION OF THE INVENTION

The present invention consists of a lock that allows the door to be locked on which it is installed by displacing one or more pins per trip, driven by springs tensioned by the latch either at the time of closing the door or in the time to open it.

In this closing and locking operation, neither the key nor the turning of a knob or handle is involved.

Likewise, the opening makes use of other springs, some of them previously tensioned when closing the door and others tensioned during the opening operation, so that, simply by pressing a button or turning a handle from the inside or key from the outside, unlock the door releasing the pins.

The most outstanding aspects of this mechanism are the lack of external energy supply in the form of an electrical, pneumatic or hydraulic source, since the energy required for its operation is obtained from the force exerted by the frame on the doorknob or doorknobs during the closing and / or opening of the door: part of the energy obtained when closing the door is used to close the pin or pins and act on the latch, and another part is stored in a set of springs for a later use in the operation opening. The energy obtained when opening the door is used so that all the pieces return to their initial position and charge the springs that will act during the closing operation. Additionally, this lock can be operated by any type of key, whether conventional, by electronic card, or by a remote signal, in which case these additional electronic devices would be the only ones that require power.

The incorporation of a remote opening system makes sense, for example, in access doors to housing communities where, in addition to a direct access, remote opening is possible through an intercom located in a distant place as well as from each living place.

According to each particular case, it is possible to replace the button or handle with a relay or allow the two mechanisms to coexist.

The basic principle of operation of this lock is to take advantage of the energy that is printed on the door leaf at the time of closing and at the time of opening, storing it in various springs that will act by automatically moving the locking pins and the rest of the pieces that make up the lock.

DETAILED EXHIBITION OF THE INVENTION The invention consists of an automatic mechanical action lock that allows the opening and closing operations to be carried out by means of a push button or handle from the inside or by means of a key from the outside, which can also be operated independently and by means of a remote operated relay .

The invention is entirely framed inside the lock box (3) and only the lock (1) is located on the door frame.

In the figures corresponding to the three examples of the invention, the boxes (3) have been shown open to show the mechanism and its position in the opening and closing situation; and, on the left, the plate (2) of the edge of the door showing the perforations that allow the exit of both the pin (4) and the handle (10, 15), plus the plate that constitutes the strike (1) since it can be configured with different perforations than the exit of the lock.

The main lock of the lock is the responsibility of the pin (4).

In the closing operation of the door, a first drive rocker (9) pushes the pin (4) supporting the end of a second rocker (7) integral with the pin (4) thanks to the energy provided by a spring that can be located in various positions and configurations according to the invention. This spring will be indicated in more detail when describing each of the embodiments of the invention. The impulse exerted on the second rocker arm (7) displaces the pin (4) by pulling it out until the end or the ends (when several lugs (4.1) are used) enter the perforations (ll) of the strike (1) destined to accommodate them. In this position the door is closed and locked.

The output of the pin (4), driven by the first drive rocker (9), tensiones a spring (5) that will serve to recover the position of the pin (4), that is, pick it up into the box (3) in the opening operation.

The pin (4) is guided in its movement by means of a shaft (6) integral with the lock box (3) that is housed inside a groove (4.2) of the pin (4).

Once the pin (4) has come out completely tensioning the recovery spring (5), a sentence (11) prevents retraction.

This sentence (11) can be removed either by means of a relay (12) operated remotely, or by means of a cylinder or bulb (14) that can be operated from the inside by means of a push button or handle, not shown in the figures, or from the outside using the key.

The handle, the push button and the key act on the cam (14.1) of a light bulb (14) which in the first part of its path acts on the sentence (11) releasing the pin (4) and allowing it (4) to insert inside the box (3). As a measure of security, the pin (4) is provided with a projection (4.3) in such a way that the cam (14.1) of the bulb (14) in the second part of its path drags said projection (4.3) forcing the pin (4) to enter the lock box (3), as if it were a conventional lock.

The sentence (11) has a recovery spring (13) that tends at all times to block the pin (4), this being possible only when the pin (4) is completely inserted into the strike (1).

It has been indicated at the outset that the drive of the pin (4) is carried out by the action of a first drive rocker (9) exerting its force on a second rocker (7); this one (7) with the axis fixed on the pin itself (4).

The second rocker arm (7), in addition to driving the pin (4), allows, without hindering, the recovery of the original position of the drive rocker (9) regardless of the pin position (4). The recovery of the position of the drive rocker (9), when the pin (4) is fully collected inside the box (3), would entail mechanical interference, - however, the rocker (7) swings overcoming the tension of a small recovery spring (8) and allows the passage of the first drive rocker (9). This second rocker (7) has its turn limited by a stop (7.1) integral with the pin (4).

Once described the way to act and recover the pin (4), it can be said that the first The rocker (9) is energized by the movement of the handle (10) either when the door is opened or when it is closed.

This storage of elastic potential energy has been carried out by means of three embodiments that are described separately.

Example first.

In this first example, shown in figures 1 and 2, the latch (10) energizes the automatic lock object of this invention during the closing of the door.

The door strike (1) does not have any perforation for the latch (10) so in the closing operation, the inclined plane (10.1) forces its introduction into the lock and this turns out to be its final position given the absence of perforations in the strike (1) that house it.

When the latch (10) is inserted into the box (3), the energy necessary for the operation of the lock is provided. This energy will be stored in a series of springs for later use in opening and closing the door.

During the entry of the latch (10) a recovery spring (10.2) is compressed so that it (10) can be re-released in due course.

In addition to compressing its recovery spring (10.2), a rod (10.3) of the latch (10) drives the primary drive rocker (9). The primary drive rocker (9) is in turn a composite rocker that is formed by three projections or arms that rotate all of them on the same axis: two (9.1, 9.2) integral with each other and an independent one (9.3) provided with a stop (9.6).

The rod (10.3) of the latch (10) exerts its impulse on the first arm (9.1) which in turn displaces the second arm (9.2) in solidarity. This second arm (9.2) is connected to a position recovery spring (9.4) and a second spring (9.5) connected to the independent third arm (9.3).

In this way, the drive of the rod (10.3) of the latch (10) drives the first two arms (9.1, 9.2) jointly, tensioning the recovery spring (9.4) and the spring (9.5) that joins said arms (9.1 , 9.2) with the third arm (9.3). This third arm (9.3) is the one that will drive the pin (4) through the rocker arm (7). The presence of the intermediate spring (9.5) allows the latch (10) to be inserted into the lock box (3) when the door is closed even though the pin (4) cannot be moved by the arm (9.3). The pin (4) will only exit the lock box (3) when it is facing the perforations (1.1) of the strike (i), at which point the arm (9.3) driven by the spring (9.5) will act on the pin (4) introducing the bolts (4.1) in said perforations (1.1).

It should be noted that, for the perfect improvement of the device, a small section (9.6) or distance stop has been included between the first and second arms (9.1, 9.2) and the third (9.3) which prevents the spring (9.5) that joins them from bringing the arms closer than a certain angle, thus keeping them apart.

At the time of opening, the pin (4) is released and removed as described; and when opening the door, the latch (10) can leave its housing driven by its recovery spring (10.2).

The primary rocker (9) can return to its original position also by its recovery spring (9.4); and as described above, without the impediment that would interfere with the second rocker (7) of the pin.

The latch (10) has a nut (19) for regulating the distance with which the latch (10) is projected outwards, thus allowing the adjustment of its entry into the housing (1.3) of the lock (1) with in order to compensate for the possible clearance between the leaf and the door frame. In addition to this regulation function, said nut (19) allows to disassemble the end of the latch (10) of the rod (10.3) and turn it, thus changing the lock by hand, so that the same lock serves both hands interchangeably.

Second example.

In Figure 3, the representation on the right corresponds to the lock when it is locked and the door closed, and the one on the left is the configuration of the lock when the door is open. In this example, two doorknobs are used, a primary doorknob (10) and a secondary doorknob (15).

Figure 4 represents a detail of the latches (10, 15) distinguishing the different inclinations of their planes.

The primary latch (10) is responsible for energizing the lock and has the particularity that its inclined plane (10.1) is on the opposite side of the first example (this inclination will be called inverse and that of the first direct example). In this example, the lock (1) does have a housing for the latch (10).

With this configuration, when the door is open the main latch (10) is inside the lock box (3). When the door is closed, the main handle (10) leaves the box (3) and enters the lock (1).

During closing, the secondary latch (15), with its direct inclination plane (15.3) and without housing in the lock (1), is inserted into the lock.

The entrance of the secondary latch (15) compresses its recovery spring (15.1) and in turn drives a rocker arm (16) with "L" in the central rod (15.2) that transforms the horizontal displacement into vertical.

The vertical movement of the rocker arm (16) moves a ratchet (17). serrated (17.1) that retains the main latch (10). The retention is carried out by the support of a projection (10.4) integral with the latch (10) in the teeth (17.1) of the ratchet (17).

The ratchet (17) is guided (17.2) vertically and includes a spring (17.3) that tends at all times to approximate the teeth (17.1) of the ratchet (17) against the projection (10.4) of the latch (10).

The release of the main latch (10) by the entrance of the secondary latch (15) allows the first (10) to be driven by the recovery spring (10.2) and lodge in a hole (1.2) of the strike (1).

When leaving the main latch (10) of the lock box (3), the primary rocker (9), which in this example is simple, with a single arm, drives the pin (4) due to the spring (18) of recovery. When the pin (4) is inserted into the strike (1), the door is closed.

Once the pin (4) is released, when the door is opened the latch (10) is forced out of its housing by entering the lock box (3) and mounting the spring (18) through the rocker arm (9) primary, thus achieving the potential elastic energy required for the operation of the lock. The introduction of the main latch (10) in the box (3) occurs thanks to the inverse inclination of its oblique plane (10.1). Once inserted in the lock box (3), the main latch (10) is locked by the ratchet (17) that retains the projection (10.4).

Third example.

In the first embodiment, the latch (10) obtained the potential elastic energy in the closing operation, - in the second example, in the opening operation, and in both cases the displacement was horizontal.

In this example, shown in Figure 5, the elastic potential energy is obtained in the closing operation using a vertical displacement of the latch (10) for which it has been set to "L" with the recovery spring (10.2) vertical.

The plate (2) of the edge of the lock box (3) has an exit slot (2.1) that allows the vertical movement of the latch (10); and, the strike (1) admits the lateral entrance of the latch (10) with an oblique recess (1.3). Thus, when the door is closed, the latch (10) is forced to rise, moving with it a outgoing (10.4) which will be the one that pushes the primary rocker (9).

This primary rocker (9) consists only of two independent arms (9.7, 9.8) connected to each other by means of a spring (9.5) that transmits the force of the latch (10) to the pin (4).

In turn, the primary rocker (9) has the recovery spring (9.4) and a stop (9.6) or small spacer arm between the main arms (9.7, 9.8).

The opening of the door, once the pin (4) is released, is what allows the latch (10) to cease to be pressed vertically by the oblique recess of the lock (1), recovering its position as a result of the recovery spring ( 10.2). Likewise, the primary rocker (9) recovers its position by the action of the spring (9.4).

The latch (10) has a nut (19) for regulating the distance with which the latch (10) is projected outwards, thus allowing the adjustment of its entry into the housing (1.3) of the lock (1) with in order to compensate for the possible clearance between the leaf and the door frame. In this example, it is not necessary to disassemble the end of the latch (10), since it serves both hands interchangeably without any modification.

Throughout all embodiments, the mobile elements have a recovery spring where in all cases the spring has consisting of a coil spring. However, the use of coil springs should not be considered as a limiting element of the invention and its embodiments, since it is possible to carry out said embodiments using any other means of storing the potential elastic energy, such as hydraulic pistons, pneumatic pistons, magnetic devices or elastic materials in general, without substantially altering the invention.

Although it has been described that action by remote means is possible, it should be noted that such remote means operate in conjunction with electromagnetic actuators or electrically powered motors to perform the opening or closing.

On the other hand, in all the embodiments of the invention, the pin (4), whose displacement is horizontal, can be replaced or complemented by pins whose displacement takes place vertically (for example by means of an eccentric), being introduced into the frame at the top and bottom of the sheet.

Variations in materials, shape, size and arrangement of the component elements, described in a non-limiting manner, do not alter the essentiality of this invention, being sufficient to proceed to its reproduction by an expert.
