TECHNICAL FIELD The present invention relates to an electrostatic strike, and more particularly, an electrostatic strike used for locking or releasing a latch bolt of a door lock device fixed to a fire door or an emergency door or a door side of an entrance door, that is, a solenoid, an operation bar, a rotation stopper, and a rotation. The interlocking action between the cams removes the stopper springs provided in the rotating stopper from the normal electrostatic strike configured to interfere with the rotation of the turner or to perform the free rotation while binding or detaching each member. The side pressure release function and the locking function of the turner are made by the operating bar slide-transferred when the solenoid is energized or released, and the turner and the rotation cam which were separated in the past are integrally formed, thereby simplifying the device structure and simplifying assembly. With slide feed Improvement of the operation efficiency of the turner's side pressure release function and the locking function according to the turning or returning action of the turning stopper by the operation bar, and the turner with the rotation interference caused by the wind pressure action while the latch bolt of the door lock device is locked to the turner. By improving the lateral pressure by the elasticity of the conventional stopper springs, and minimizing the number of fittings in the device by reducing the number of parts that are fitted together, the fitting tolerances generated when assembling the turner and the rotating cam using the hinge shaft as in the prior art Due to the clearance between the elements and the operation process becomes unstable through this can solve the problem that the standardization of the operation of the device can not be solved, and in particular, the forced opening rotation prevention jaw at the other end of the operation bar connected to the bottom of the rotation stopper As it is formed integrally, elastic suit of operating spring is released with solenoid de-energization In conjunction with the slide feed action of the operating bar according to the force, the pivoting stopper returns to its original position, and a strong force from the outside is applied to the pivoting stopper via the turner and the rotating cam to force the latch bolt of the door lock device that is locked by the turner. Even if it is applied to the forced opening rotation prevention jaw while holding the lower end of the rotation stopper to be rotated to the rotational action of the turner for forcibly releasing the locked latch bolt and the electrostatic strike to prevent the forced opening of the door through it .

In general, hospitals, buildings, government offices, schools, hotels, and performance halls are equipped with emergency or fire doors to allow people in the room to evacuate to the outside quickly in case of an emergency such as a disaster or fire. Emergency or fire doors can be easily opened from the inside of the room, and a touch-operated panic device (aka, panic bar) is installed on the door side to allow passage through the door without any obstacles, or solenoid operation according to energization or de-energization. Interfering with the rotation of the turner through or freely through the electric lock striker locking / unlocking the latch bolt of the door lock device is installed on the door frame will be used.

Thus, the description of the panic device among the panic device or the electric striker installed on the door side or the door frame side will be omitted so that the insider can evacuate the locked door quickly and evacuate quickly in case of an emergency such as a disaster or fire. It will be described briefly with respect to the electrostatic striker in contrast to the present invention.

The conventional electrostatic striker 100, as shown in Figure 1, the upper portion is open and mounted to the door frame 110; A hinge shaft 114 fixedly installed at both side walls of the case 110 and disposed in a horizontal direction; The hinge shaft 114 includes a torsion spring 122 and is rotatably coupled to each other, and at the same time, the locking blade 120 is located at the front of the case 110 and rotates according to the operation of the solenoid. A rocker 116 which rotates and locks or releases the latch bolt of the door lock device; The mass 126 including the torsion spring 134 is coupled to the hinge shaft 114, and the finger 128 pressed by the latch bolt Rb passed through the rocker 116 on one side of the mass 126. Latch detection unit 124 is formed integrally with; A limit switch (not shown) installed on a bottom surface of the case 110 and turned on and off by a latch detection unit 124; A guard (160) serving as a cover (110), which is installed at an upper end of the case (10) and is formed with a guide hole (166) through which a finger (128) is exposed; The solenoid 140 is installed inside the case 110 and includes a rod 142 having a diameter step corresponding to a rod insertion groove 119 formed at the bottom of the arm 118 of the rocker 116 at the distal end thereof. . Reference numeral 162 denotes a fixing plate 162 for fixing the case 110 to the door frame.

In the case of the conventional electrostatic striker 100 configured as described above, when the door is opened, power is cut off to the solenoid 140 so that the rod 142 returns to its original position (reverse state) and is formed at the bottom of the arm 118 of the rocker 116. The rod inserting groove 119 and the small diameter portion 142b of the rod 142 are correspondingly engaged to allow the free rotation of the rocker 116 so that the door can be opened such that the locking is released. When the door is locked, the rod insertion groove 119 formed at the bottom of the arm 118 of the rocker 116 by applying power to the solenoid 140 to advance the rod 142 is the large diameter portion 142a of the rod 142. In response to the locker 116, the locker 116 can not be rotated to lock the door, such as locking the current, supplying and blocking current, and controlling the entrance and exit, and determining whether the door is open, closed or disconnected. Effective entry and exit There is an advantage that can be interrupted with.

In addition, there is a locking device for a door disclosed in Utility Model Registration No. 0353556 as a structure similar to an electrostatic striker operated in the above manner.

However, when the wind pressure (side pressure) by the outside air acts on the door side in the state in which the door is closed and locked as shown in FIG. 2A, the electrostatic striker 100 as shown in FIG. Latch bolt (Rb) of the door lock device (DR) that is locked to the locking device to pressurize the rocker 116, the locker 116 received the pressing force is also interlocking action to rotate the locker 116 of the locker (116) The rod insertion groove 119 formed at the bottom of the arm 118 presses the large diameter portion 142a of the rod 142 corresponding to the rod insertion groove 119 of the rocker, and the like, whereby As described above, even when the large diameter portion 142a of the rod 142 is pressurized by the rotational pressurization action of the rocker 116, the energization of the solenoid for opening the door in case of an emergency such as a disaster or fire is released. Presses the large diameter portion 142a of the rod 142. Since the pressing force of the rocker is much greater than the return force of the solenoid, the rod shovel formed at the bottom of the arm 118 of the rocker 116 as the rod 142 returns to its original position (reverse state) as in the case of opening the door described above. The groove 119 and the small diameter portion 142b of the rod 142 are not coupled to each other so as to form a freely rotatable state of the rocker 116, and the rod 142 according to the rotational pressing action of the rocker 116. The large diameter portion 142a is continuously held in the locked state such that the door is locked, resulting in a large problem such that the room does not open the door quickly resulting in loss of life.

Accordingly, in order to solve the above-mentioned conventional problems, the door is opened and closed by locking or unlocking by solenoid operation in correspondence with the latch bolt of the door lock device fixed to the door of the fire door or emergency door or the door. "Electrostatic striker", which was previously filed by the applicant and published in a patent on February 01, 2010, to release the latch bolt locked by the solenoid actuation to open the door more smoothly during wind pressure (lateral pressure) action. (Patent Publication No. 2010-0010150) has been proposed, which includes a solenoid, a door opening / closing sensor, an operating bar detecting sensor, a spring, and an operating bar connected to the solenoid in a housing sealed by a rear cover thereof, Rotating stopper rotatably installed on one side of the turner in contact with one side end, and a state in contact with one end thereof Through the interlocking action of the rotating cam coupled to one side of the low turner, it is configured to interfere with the rotation of the turner or free rotation while mutually binding or leaving the rotating stopper and the rotating cam.

However, in the case of an electrostatic striker (Patent Publication No. 2010-0010150) previously filed and disclosed by the present applicant as described above, the rotating stopper is rotatably installed on one side of the turner in contact with one end of the operation bar. In addition to the stopper spring, the rotating cam and the turner are structured separately from each other, so the device structure is very complicated and the number of parts of the elements to be fitted together is very cumbersome and inconvenient. There was also a big problem, such as long working time.

Further, in the case of the conventional electrostatic striker, the stopper spring is provided on the pivoting stopper as described above, so that the inclination of the rotary cam coupled to one side of the turner by the wind pressure (side pressure) action in the latch bolt of the door lock device is locked to the electrostatic striker. The contact portion contacted between the cam portion and the roller of the rotation stopper is pressed by the rotational force of the turner by the latch bolt, and the rotation cam and the rotation stopper are rotated in contact with each other. In order to release the binding state of the stopper, the latching bolt is locked by the operating bar and the latching bolt is unlocked by the operating bar.The latching bolt is locked by the engagement bar between the rotating cam and the rotating stopper by the elastic restoring force of the stopper spring. When switching to the open state, the force of the stopper spring There was also a problem such that the unlocking force of the latch bolt against the wind pressure (side pressure) action is not smooth due to the reduction of the pressing force of the operation bar for rotating the copper stopper.

In addition, in the construction of the conventional electrostatic striker, the number of components to be fitted to each other as described above is very large, and accordingly, the fitting portion in the device is inevitably increased. Moreover, each turn unit that is separated from each other using a hinge shaft is formed. The gap between the elements is caused by the fitting tolerance generated when assembling you and the rotating cam, and the operation process due to the interaction between the solenoid, the operating bar, the rotating stopper, the rotating cam and the turner becomes unstable, and thus There was also a problem that could not be achieved.

In addition, in the case of the conventional electrostatic striker, there is no means for preventing the locked latch bolt from being forcibly released by applying an external forcing force to the turner locking the latch bolt while the latch bolt of the door lock device is locked. Due to its structure, when external forcing force acts on the closed turner where the latch bolt is locked through the binding between the rotation cam and the rotation stopper by the elastic restoring force of the stopper spring, it acts on the rotation stopper through the interconnected turner and rotation cam. The external illegal intruder forcibly opens the locked door and invades the interior by rotating the turner and forcibly opening the door by turning the clockwise direction when the rotation stopper is opened by the external forcing. If you are stolen or have an insider It was also hurt by a particle or problems such as inevitably face a dangerous situation, such as feeling the threat of life.

In addition, in the case of the conventional electrostatic striker, as a soft material (zinc), since the turner holder and the housing in which the turner is rotatably coupled by the hinge shaft are integrally formed, not only the fracture strength due to external impact is weak, but also the steel material (stainless steel). There was also a problem such that the turner holder by the rotational action of the turner and the hinge shaft, that is,), that is, the hinge shaft coupling hole of the turner holder made of soft material (zinc), greatly reduced the durability of the entire apparatus.

The present invention has been made in order to solve the conventional problems as described above, so as to interfere with the rotation of the turner or to free rotation while releasing or binding between each member through the interlocking action between the solenoid, the operation bar, the rotation stopper and the rotation cam. To remove the stopper spring provided in the pivoting stopper, the side pressure release function and the locking function of the turner according to the pivoting action of the pivoting stopper are performed by an operation bar which is slide-transferred according to the energization or release of the solenoid. At the same time, the turner and the rotating cam, which have been conventionally separated, are integrated into one another, simplifying the structure of the device and simplifying assembly, and lateral pressure releasing and locking of the turner due to the rotation or return action of the rotary stopper by the slide-operated operating bar. Door lock on the operation efficiency and turner for function It is an object of the present invention to improve the side pressure on a turner in which a rotational interference is caused by wind pressure in the state in which the latch bolt of the device is locked by the elastic force of the conventional stopper spring.

In addition, in the case of the present invention, by configuring as a structure integrated with each other for the conventional turner and the rotating cam, which were separated into separate units as described above, by reducing the number of parts of the elements that are fitted to each other to minimize the state of fitting in the device As shown in the above, the gap between the elements is generated due to the fitting tolerance generated when assembling the turner and the rotating cam using the hinge shaft, and the operation process becomes unstable, thereby eliminating the problem of standardization of device operation. Another purpose is to ensure that the operation of the device can be more stabilized and standardized even when the interfit coupling is made.

And, in the present invention, as the forced opening rotation prevention jaw is integrally formed at the other end of the operation bar connected to the lower end of the rotation stopper, the slide transfer action of the operation bar according to the elastic restoring force of the operation bar spring with release of solenoid energization The forced opening rotation stopper is rotated even when a strong force is applied from the outside to the rotation stopper through the turner and the rotation cam to force the latch bolt of the door lock device that is locked by the turner as the rotation stopper returns to its original position. Another purpose is to prevent the forcible opening of the door through the rotational action of the turner for forcibly releasing the locked latch bolt while holding the lower end of the pivoting stopper.

In addition, in the case of the present invention, as the holder body coupled to the hinge shaft, which is the rotation point of the turner, is bolted to a separate unit in the housing, compared to the conventional structure in which the turner holder and the housing are integrally formed as a soft material (zinc). It is another object to improve the durability of the entire device as the hinge shaft coupling hole of the turner holder by the rotational action of the steel (stainless steel) turner and hinge shaft as well as the failure strength due to external impact.

Electrostatic strike of the present invention, the latch detection unit, the operating rod, the door opening and closing detection sensor, the operation bar detection sensor through the interlocking action between the solenoid installed in the housing, the operating bar, the rotation stopper and the rotation cam to release the binding or separation between each member Rotation of the rotary stopper which is interlocked by an operating bar which is slid by the energizing or releasing of the solenoid of the electrostatic strike configured to interfere with the rotation of the turner coupled to the center of the front of the housing by the hinge shaft. Alternatively, a stopper actuating protrusion and an actuating protrusion coupling groove are formed at one side of the lower end of the rotation stopper and the other end of the actuating bar so that the pressure release function and the locking function of the turner according to the return action are formed, respectively,

When the slide of the operation bar is moved, the operating projection coupling groove hits the rotation stopper operation projection so that the stopper operation projection is inserted into the operation projection coupling groove downwardly and protrudes according to the traveling direction of the operation bar. The actuating protrusion coupling groove is formed in the form of a long hole having a free space of the stopper actuating projection so that the actuating stopper is also rotated or returned along with being transported.

Both sides of the actuating protrusion coupling groove are positioned to correspond to the stopper actuating protrusion inserted downward to protrude downward, and the striking protrusion for hitting the stopper actuating protrusion more smoothly during the slide transfer of the actuating bar is bent downward.

According to the present invention, through the interlocking action between the solenoid, the operation bar, the rotation stopper and the rotation cam to the rotation stopper of the conventional electrostatic strike configured to interfere with the rotation of the turner or to free rotation while releasing or binding between each member. By removing the stopper springs provided at the same time, the turner and the rotating cam which have been conventionally separated are integrated to simplify the structure of the device and to simplify the assembly. Excellent efficiency, such as the operation efficiency of the release function and the locking function, and the side pressure on the turner with the rotational interference caused by the wind pressure action while the latch bolt of the door lock device is locked to the turner can be improved by the elastic force of the conventional stopper spring. have.

In addition, in the case of the present invention, by configuring as a structure integrated with each other for the conventional turner and the rotating cam, which were separated into separate units as described above, by reducing the number of parts of the elements that are fitted to each other to minimize the state of fitting in the device As shown in the above, the gap between the elements is generated due to the fitting tolerance generated when assembling the turner and the rotating cam using the hinge shaft, and the operation process becomes unstable, thereby eliminating the problem of standardization of device operation. There is also the effect that the operation of the device can be more stabilized and standardized even with the interfit coupling.

And, in the present invention, as the forced opening rotation prevention jaw is integrally formed at the other end of the operation bar connected to the lower end of the rotation stopper, the slide transfer action of the operation bar according to the elastic restoring force of the operation bar spring with release of solenoid energization The forced opening rotation stopper is rotated even when a strong force is applied from the outside to the rotation stopper through the turner and the rotation cam to force the latch bolt of the door lock device that is locked by the turner as the rotation stopper returns to its original position. While holding the lower end of the rotation stopper to be turned there is an effect that can prevent the rotation of the turner for forcibly releasing the locked latch bolt and the forced opening of the door through it.

In addition, in the case of the present invention, as the holder body coupled to the hinge shaft, which is the rotation point of the turner, is bolted to a separate unit in the housing, compared to the conventional structure in which the turner holder and the housing are integrally formed as a soft material (zinc). As well as the breaking strength due to external impact, the hinge shaft coupling hole of the turner holder due to the rotational action of the turner and the hinge shaft of the steel material (stainless steel) is worn, and the durability of the entire device may also be improved.
