Method and apparatus for preventing door picking

〔Technical field〕

According to the present invention, the door lock is locked and the door lock is locked, thereby locking the door lock and opening the door from outside.

The present invention relates to a method and a device for picking a door to prevent locking.

[Technical background]

Conventionally, methods to prevent picking of a locked door include improving the internal structure of the door lock itself, or installing a special door lock inside the door, that is, inside the chamber. .

However, the conventional security door locks or security devices as described above have problems that they are expensive, complicated to install, and difficult to completely prevent picking.

[Disclosure of the Invention]

The present invention has been made in order to solve the above-described problems, and has a simple operation method that exhibits a reliable security function. An object of the present invention is to provide a door picking prevention method and a device capable of withstanding use of a door.

The door picking prevention method according to the present invention is a method for rotating a door lock integrally with a room-side thumb turn of a door lock in a space formed to open at least on one side of a thumb / sun cover having a magnetic attraction function. The thumb turn cover is accommodated, and the surface of the thumb turn cover on the door side is A lock member provided on the thumb-turn cover is operably attached when the thumb-turn force bar is rotated integrally with the above-described thumb-turn to be in a locked state by being attracted to a magnetic material attached to a door surface. It is characterized in that the rotation of the door lock is locked by engaging with a magnetic material.

In addition, a door picking prevention device according to the present invention includes a thumb-turn cover having at least one side opening, and a space formed therein for accommodating a room-side thumb turn of a door lock so as to rotate integrally therewith. A magnet provided on the opening end face of the thumb cover, a magnet adsorbing the magnet to one face, and a magnetic body affixing the other face to the door face, and being operable on the thumb cover. And a lock member engaged with the magnetic body.

According to the invention described above, the indoor thumb turn of the door lock has an opening on one side, is accommodated by the thumb turn cover having a space inside the opening, and is turned integrally with the thumb turn cover. Move. This summer turn cover has a magnetic attraction function, and, while covering the thumb turn as described above, attracts the opening end face to the magnetic body attached to the door surface.

In this state, for example, when the adsorption surface between the thumb turn cover and the magnetic material is flat, only the magnetic adsorption force of the thumb cover and the force according to the friction coefficient between these adsorption surfaces are used. Therefore, it is possible to resist the unlocking operation from the outside of the door. On the other hand, from the indoor side, the thumb turn cover can be gripped and the thumb rest can be rotated with a smaller force each time. Therefore, by setting this frictional force appropriately, it is possible to obtain a sufficient picking prevention effect even without a lock member described later.

To prevent picking, the thumb turn cover can be used to cover the thumb when the thumb turn is locked. The rotation of the thumb turn force bar and, consequently, the rotation of the thumb spring are prevented by engaging the locking member provided on the magnetic member with the magnetic member.

The magnetic body is formed by including a magnetic material, and has a suction surface capable of adsorbing the thumb-turn cover and generating an adsorption force sufficient to overcome the unlocking force from the outside of the door lock. It is desirable to have It is also possible to counter the above unlocking force by making the surface of the suction surface rough, or providing the suction surface with irregularities. The magnetic material may be a relatively thick plate-like material or a thin sheet-like material. However, in the present invention, the shape of the magnetic body is not limited, but may be various shapes according to the shape of the opening end face of the thumb turn cover.

Also, the magnetic material is attached to the door surface by using, for example, a double-sided adhesive tape or an adhesive that can be peeled off with a release agent so that it can be returned to the original state before the mounting. It is desirable. This is particularly advantageous for installation in rental housing.

In this way, it can be easily installed without substantial processing on the door, so there is no need to ask a contractor to perform the installation work, and it has a very simple configuration, and the strength of each part is reduced. By keeping it sufficiently, it can withstand long-term use.

As the lock member, various shapes and operation modes can be adopted.For example, the lock member can be formed in a hook shape to be hooked on a magnetic body. . Further, it is also possible to form the lock member in a pin shape, and to provide the lock turn member with respect to the opening end surface of the thumb-turn cover so that the tip end of the lock member protruding from the opening end surface is engaged with the magnetic body. It is. More preferably, a recess (which may be a hole) having a size corresponding to the diameter of the locking member is formed at a position corresponding to the magnetic material, and the tip of the locking member is inserted into the recess. So that In order to realize the integral rotation of the thumb turn and the thumb turn cover, it is desirable to make the space of the thumb turn cover accommodating the thumb turn conform to the shape of the thumb turn cover. Due to the existence of various types, it is difficult for a single type of thumb to cover all these types of thumb turns. Therefore, the shape and size of the space are formed so as to be able to accommodate the thumb turns of these evenings, and gaps not occupied by the thumb turns are filled with a curable plastic material.

In actual use, the curable plastic material is filled in the above space of the saturn cover, and in this state, the saturn cover is pressed against the samutong. The curable plastic material is preferably a material that cures with time in air, and a quick-drying material that cures in a relatively short time. As described above, the curable plastic material can be easily formed into the shape of a thumb-turn in the space, while the curable plastic material can be adsorbed and held on the thumb-turn.

The space for the thumb cover that houses the sumtant should have a shape such as an ellipse or polygon that prevents the filled hardening plastic material from moving inside when viewed from the direction of the rotation axis of the thumb turn. Is desirable. In addition, it is possible to make the space have a substantially circular shape. In that case, however, it is desirable to prevent rotation by forming irregularities on the inner surface.

Further, the picking prevention device is configured to receive a command signal such as a locking and unlocking signal from a remote controller, and drive the locking member by driving means in accordance with the command signal. It is also possible. This makes it possible to use the picking prevention device according to the present invention not only when the user is in the room but also when going out. The driving means can be provided with various types of actuators such as solenoids and geared motors.

Also, another picking prevention device according to the present invention is a door lock A door that includes a thumb cover that covers the side thumb turn so as to rotate together with the thumb turn, and locking means that locks the rotation of the thumb turn accompanying the rotation of the thumb turn from the locked position. In the picking prevention device, the locking means includes: a lock member provided to be detachable from the thumb turn cover; and a driving means for engaging and disengaging the lock member to and from the thumb pad. It is characterized by.

According to the invention, the lock member, which is detachably attached to the thumb turn cover that covers the thumb turn so as to rotate integrally with the indoor thumb thumb of the door lock, is engaged by the driving means. Deactivate. In other words, for example, when the thumb turn is locked, the lock member locks the thumb turn cover, so that the rotation of the thumb turn cover and, consequently, the rotation of the thumb turn cover. Therefore, it is possible to reliably prevent picking.

The lock member may have various shapes and operation modes. For example, the lock member may be formed in a hook shape and hooked on the thumb-turn cover. In addition, the locking member is formed in a pin shape, and is driven so as to advance and retreat in a normal direction with respect to the rotation direction of the thumb turn cover, so that the distal end portion of the locking member is engaged with the summer turn cover. It is also possible. More preferably, a recess (which may be a hole) having a size corresponding to the diameter of the locking member is formed at the corresponding turning position of the thumb-turn cover, and the distal end of the locking member is formed in the recess. Insert

The lock member and a driving means for driving the lock member may be housed in a housing and provided as a unit part.

The casing is attached to, for example, a door surface, but it is desirable to attach the casing to the door surface via holding means for holding the casing in order to easily adjust the mounting position. In this case, the holding means may adjust the position of the housing with respect to the door surface after adjustment. For example, a fixing means may be provided so as not to be changed by the vibration due to the opening and closing operation of the door.

Specifically, the holding means comprises a holder provided with a magnet and a pedestal made of a magnetic material, and the housing is held by the holder, and the holder is attached to a pedestal attached to a door surface. It can be magnetically attracted to the surface.

It is desirable to attach the holding means to the door surface using, for example, a double-sided adhesive tape that can be peeled off with a release agent so that the holding means can be returned to the original state before the attachment. This is particularly advantageous for installation in rental housing.

As described above, since the door can be easily installed without substantial processing to the door, there is no need to ask a contractor to perform installation work, and the structure is very simple, and the strength of each part is sufficiently high. By keeping it, it can withstand long-term use.

Further, the holding means is configured to hold the housing in a reversible manner, and the locking member is arranged offset from the inversion axis so that the holding means can be held only by the holding means. Therefore, the engagement position of the lock member can be easily changed, and it is possible to cope with various conditions when attaching the holding means to the door surface.

The locking means is configured to receive a command signal such as a locking and unlocking signal from a remote controller, and to drive the locking member by a driving means in accordance with the command signal. It is also possible. This makes it possible to use the picking prevention device according to the present invention not only when the user is in the room but also when going out. The driving means can include various types of actuators such as solenoids and motors with gears.

In order to realize the integral rotation of the thumb turn and the thumb turn cover, the recess of the thumb turn cover for accommodating the thumb turn is formed in the thumb turn cover. It is desirable to match the shape of the thumb pattern, but in fact, since there are various types of thumb pattern shapes, it is not possible for a single type of thumb cover to cover all these types of thumb patterns. Have difficulty. Therefore, the shape and size of the recesses are formed so as to be able to accommodate the thumb turns of these evenings, and the gaps not occupied by the thumb turns are filled with a curable plastic material.

In actual use, a curable plastic material is filled into the above-mentioned recess of the thumb turn cover, and in this state, the thumb turn cover is pressed against the thumb evening. The curable plastic material is preferably a material that cures with time in air, and a quick-drying material that cures in a relatively short time. As described above, the curable plastic material can be easily formed into the shape of a thumb-turn in the space, while the curable plastic material can be adsorbed and held on the thumb-turn.

It is desirable that the space of the thumb-turn cover for accommodating the thumb-turn has an elliptical shape, a polygonal shape, or the like, such that the curable plastic material to be filled does not move inside when viewed from the rotation direction of the thumb-turn. It is also possible to make the space have a substantially circular shape. In this case, it is desirable to prevent rotation by forming irregularities on the inner surface.

The pedestal 400 is provided with a position adjusting groove 402 which is long in the vertical direction at a position corresponding to the positioning pin 302 of the holder 300 which is attracted to the other surface. As described above, the holder 300 holding the apparatus main body 200 can be moved up and down with respect to the pedestal 400 attached to the door surface Cf.

As shown in FIGS. 14 (a) and (b), the device main body 200 moves the locking member 201 forward and backward on the lower surface thereof, and engages with the engaging portion 30 of the thumb turn cover 1 c located below the locking member 201. The rotation of the thumb turn cover 1c is locked by being inserted into the gap between the two. In the following embodiments, an example of the type-shaped thumb-turn cover 1c is illustrated, but the same applies to other types of thumb-turn covers, and a description thereof will be omitted.

When the lock member 201 shown in FIG. 14 (a) is pulled into the housing 200c (unlocked state), the lock member 201 interferes with the thumb turn cover 1C. It is possible to freely rotate Samturn D (not shown here) together with Samtern cover 1c. On the other hand, when the thumb turn cover 1c is rotated to the locked position of the thumb turn D, in this state, the engagement portion 30 of the thumb turn cover 1c is set so as to face upward as described above. As shown in FIG. 14 (b), when the lock member 201 is in a protruded state (locked state), the lock member 201 is engaged with the engagement portion of the thumb turn cover 1c. 30 turns into a gap The rotation of the par 1 c is prevented. As a result, the thumb ring D inside the thumb turn cover 1c is rotated by the picking operation, and the operation to the unlock position can be reliably prevented.

As shown in FIG. 15, the apparatus main body 200 includes a control unit 211, a manual switch 203 connected to the control unit 211, a signal receiving unit 212, a pin driving unit 210, and a buzzer 21 3. And the like.

As shown in FIG. 12, the manual switch 203 is a push button type switch provided on the upper surface of the housing 200c. The signal receiving section 212 receives the locking and unlocking signals from the remote controller 500 of the locking means 100.

The remote controller 500 is a small type using a communication method similar to the so-called “keyless entry” of a car, and includes a locking operation button 502 (indicated by “LO CK” in FIG. 15) and An unlocking operation button 503 (shown as "OPEN" in 01-15) and an operation confirmation lamp 501 configured to be turned on when these buttons are operated are provided. The remote controller 500 transmits a lock signal when the lock operation button 502 is pressed, and transmits a lock release signal when the lock release operation button 503 is pressed. Has become.

The pin driving section 210 converts the rotational force of the DC motor (not shown) by a reduction gear by a reduction gear to convert the rotation of the lock member 201 into an advancing and retreating operation. The buzzer 2 13 is energized in accordance with an instruction from the control unit 21 1, and emits a sound confirming the operation of the device main body 200.

With the above-described configuration, for example, when the manual switch 203 is pressed, or when the signal receiving unit 212 receives a lock signal from the remote controller 500, the control unit 211 sends this signal. Upon recognition, the pin drive section 210 is energized to operate the lock member 201 so as to protrude, while the buzzer 213 is energized to notify the operation completion.

Thereafter, if manual switch 203 is pressed again, or When the communication unit 212 receives the lock release signal from the remote controller 500, the control unit 211 recognizes this, and reverses the mode of the pin drive unit 210 to release the lock member 201. Energize the buzzer 2 1 3 to notify the completion of operation.

Next, a method of adjusting the locking means 100 will be described in detail with reference to FIGS. 16 (a) and (b). The device body 200 has substantially symmetrical shapes in the left, right, front and rear directions, respectively, and is inverted around the central longitudinal axis L (indicated by a dashed line in FIGS. 16 (a) and (b)). So that it can be installed.

On the other hand, the lock member 201 of the apparatus main body 200 is offset from the longitudinal axis L to one of the left and right sides, so that when the apparatus main body 200 is installed upside down. The left and right positions of the lock member 201 can be changed, and the anti-picking device according to the present embodiment is a door C of a type that opens rightward outward as shown in FIG. It can be easily installed on the door C that opens to the left as shown in 6 (b).

Also, as shown in FIGS. 17 (a) and (b), by loosening the left and right setscrew 205 described above and moving these shafts along the angle adjusting groove 305, the device body 200 The attitude with respect to the door surface Cf (the angle α in FIG. 17 (b)) can be changed. For example, even when the distance from the door surface Cf to the thumb turn D is large, the tip of the lock member 201 can be changed. By adjusting the position of the part, the tip part can be properly engaged with the engaging part 30 of the thumb turn cover 1c.

Further, as shown in FIGS. 18 (a) and (b), the holder 300 which is attracted to the pedestal 400 by the above-described magnet 301 is provided with a positioning pin 302 projecting toward the door surface Cf side. By moving along the adjustment groove 402, the tip of the lock member 201 is thumb-turned. It is also possible to appropriately adjust the length d of the cover 1c engaging with the engaging portion 30. Note that FIG. 18 (b) shows only the state where the holder 300 has been moved downward with respect to FIG. 18 (a), but it may be moved upward according to the setting of the position adjustment groove 402. Needless to say, this is possible.

Further, as shown in FIG. 19, when the chain rail 600 of the door chain is installed above the thumb turn D, the locking means 100 may not be able to be installed here. It can also be placed on the side of Samtern D (right side in Fig. 19). In such a case, it is desirable to configure the thumb-turn cover to have a plurality of engaging portions 30 like the UFO-type thumb-turn cover 1b.

In the above embodiment, the holder 300 covers the apparatus main body 200 from both the left and right sides by the door surface Cf side and the arm portion 310. In addition to this, the holder 300 also covers from below. The lower holding portion may be formed with a cutout or a hole through which the lock member 201 can pass. In this case, the lock member 201 is strengthened against bending in the left-right direction. Further, in this case, the angle adjusting groove 305 can be formed not in the arm portion 310 but in this lower holding portion.

The locking means 100 of the picking device according to the present invention is, for example, a lock member 201 formed of a harder material, and in addition to the door C as in the present embodiment, a so-called "kannuki" such as a sliding door. It is also possible to use it as. In particular, when the lock member 201 is used as a cannula, a large bending force in the left-right direction is applied to the lock member 201. Therefore, it is desirable to form the lower holding portion in the holder 300 as described above.
