  However, in the opening device disclosed in the above-mentioned conventional patent document 1, the vertical movement of the moving member is prevented by inserting the dead bolt of the final lock into the hole of the moving member. If you try to move the handle, there will be rattling between the dead bolt and the hole of the moving member, and since the dead bolt is relatively small and its mechanical strength is low, a large force acts on the lock and the lock Could break down. On the other hand, if the structure is such that the deadlock bolt is engaged with the frame, not the hole of the moving member, the box lock can be unlocked by operating the handle of the box lock while the main lock is locked. In this case, there is a problem in that the adhesion of the door frame to the frame is lowered and the performance of the door body cannot be exhibited.

  An object of the present invention is to provide a locking system for a gremon handle, in which the gremon handle does not move and does not damage the locking parts even if a large force is applied to the handle while the door is locked. Is to provide. Another object of the present invention is to prevent deterioration in performance such as electromagnetic shielding of the door and adhesion to the frame of the door due to the ability to operate the gremon handle in the locked state of the door. It is to provide a lock system for a gremon handle.

  As shown in FIGS. 1 to 3 and 9, the first aspect of the present invention is a frame 12 attached along the periphery of the opening 15 of the building wall, and one side edge of the frame 12. A door 11 that is pivotally attached to close the opening 15 so that the opening 15 can be opened and closed, and a gremon mechanism that draws the door 11 toward the frame 12 when the opening 15 is closed by the door 11 to closely contact the periphery of the door 11 with the frame 12 13, and a gremon mechanism 13 is pivotally attached to the center of the other side edge of the door 11 and a frame body connected to the gremon handle 14 from the center of the other side edge of the door 11. A first locking member 21 that protrudes and protrudes toward the frame 12, and a second locking member 22 that is connected to the gremon handle 14 via the upper rod 16 and protrudes from the upper part of the other side edge of the door 11 toward the frame 12. , Via lower rod 17 on gremon handle 14 It is formed in the frame 12 which is connected and the 3rd locking tool 23 which protrudes and protrudes toward the frame 12 from the lower part of the other side edge of the door 11 and the 1st-3rd locking tools 21-23 is opposed. In a door opening / closing structure having first to third locked holes 12a to 12c that can lock the third locking tools 21 to 23, the first to third locking is performed by operating the gremon handle 14. Handle locking means 36 is provided at the upper end of the upper rod 16 or the lower end of the lower rod 17 when the tools 21 to 23 are locked in the first to third locked holes 12a to 12c. It is characterized by that.

  The second aspect of the present invention is an invention based on the first aspect. As shown in FIGS. 1 to 3 and 9, the center of the upper bell crank 19 is located above the door 11 via the upper shaft 24. The upper end of the upper rod 16 is pivotally attached to the base end of the upper bell crank 19, the second locking member 22 is provided at the distal end of the upper bell crank 19, and the handle lock means 36 is connected to the upper portion of the door 11.

A handle sensor 39 that detects that the first to third locking members 21 to 23 are locked in the first to third locked holes 12 a to 12 c, and an object to be adsorbed 37 that is accommodated in the upper portion and inside of the door 11. Electromagnet that adsorbs 1, the release means 42 for releasing the magnetic force of the electromagnet 41, characterized in that a control circuit 44 for controlling the electromagnet 41 based on the detection outputs of the steering wheel sensor 39 and the releasing means 42.

The third aspect of the present invention is the invention based on the first aspect, and further, the center of the lower bell crank is pivotally attached to the lower part of the door via the lower shaft, and the lower end of the lower rod is connected to the base end of the lower bell crank. A third locking member is provided at the tip of the lower bell crank, and a handle lock means is accommodated in the lower part of the door and is movable in the vertical direction, and is formed of a magnetic material. A motion conversion mechanism that converts the rotation into a vertical motion of the object to be adsorbed, and a handle that detects that the first to third locking devices are locked in the first to third locked holes by operating the gremon handle.

A fourth aspect of the present invention is an invention based on the second or third aspect, and as shown in FIGS. 1 and 2, the motion conversion mechanism 38 includes a lever / pin mechanism, a cam mechanism, a pinion It is either a rack mechanism or a link mechanism.

  In the locking system of the first aspect of the present invention, when the first to third locking tools are locked in the first to third locked holes by operating the grip lemon handle, the operation of the grip lemon handle is disabled. Since the handle lock means is provided at the upper end of the upper rod or the lower end of the lower rod, even if a large force is applied to the handle while the door is locked, the operation of the gremon handle can be operated. The gremon handle does not move. As a result, the locking parts such as the handle lock means are not damaged. If the dead bolt of the lock is engaged with the frame instead of the hole of the moving member, in the conventional opening device, the lock of the box lock is operated by operating the handle of the box lock while the lock is locked. However, in the present invention, the electromagnetic wave shielding property of such a door and the adhesion property of the door to the frame were reduced. It is possible to prevent a decrease in performance. That is, in the present invention, since the gremon handle cannot be operated with the door locked, performance such as electromagnetic shielding of the door and adhesion to the door frame deteriorates when the door is locked. There is nothing.

  In the lock system according to the second aspect of the present invention, when the grip of the electromagnet is operated by the release means with the door closed, the electromagnet does not exhibit the magnetic force that attracts the object to be adsorbed. The first to third locking tools can be detached from the first to third locked holes. At this time, the upper rod connected to the glemon handle is raised or lowered, and the upper bell crank and the upper shaft rotate. Therefore, the lever pulls the engaging pin together with the moving body, and the attracted body is separated from the electromagnet. On the other hand, when the opened door is closed and the gremon handle is operated, the first to third locking tools are locked to the first to third locked holes. At this time, the upper rod connected to the gremon handle is lowered or raised, and the upper bell crank and the upper shaft rotate. Therefore, the lever pushes the engagement pin together with the moving body, and the attracted body comes into contact with the electromagnet. At the same time, since the handle sensor detects that the first to third locking tools are locked in the first to third locked holes by the operation of the gremon handle, the control circuit is based on the detection output of the handle sensor. Energize the electromagnet. As a result, the electromagnet adsorbs the object to be adsorbed by its magnetic force, so that the door is locked. After that, even if a large force is applied to the handle when trying to operate the handle, the handle does not move. Moreover, since locking parts such as an electromagnet and a motion conversion mechanism are robust, these parts are not damaged.

  In the locking system according to the third aspect of the present invention, when the grip of the electromagnet is operated by the releasing means in a state where the door is closed and then the GLemon handle is operated, the electromagnet does not exhibit the magnetic force to attract the object to be adsorbed. The first to third locking tools can be detached from the first to third locked holes. At this time, the lower rod connected to the glemon handle is raised or lowered, and the lower bell crank and the lower shaft rotate. Therefore, the lever pulls the engaging pin together with the moving body, and the attracted body is separated from the electromagnet. On the other hand, when the opened door is closed and the gremon handle is operated, the first to third locking tools are locked to the first to third locked holes. At this time, the lower rod connected to the gremon handle is lowered or raised, and the lower bell crank and the lower shaft rotate. Therefore, the lever pushes the engagement pin together with the moving body, and the attracted body comes into contact with the electromagnet. At the same time, since the handle sensor detects that the first to third locking tools are locked in the first to third locked holes by the operation of the gremon handle, the control circuit is based on the detection output of the handle sensor. Energize the electromagnet. As a result, the same effects as described above are obtained.

At this time, the intermediate connecting tool 31, the upper rod 16 and the upper connecting tool 26 connected to the gremon handle 14 are lowered and the base end side of the upper bell crank 19 is rotated downward, so that the upper shaft 24 is shown in FIG. The lever 46 pushes the engagement pin 48 together with the moving body 47 so that the attracted body 37 contacts the electromagnet 41. At the same time, since the handle sensor 39 detects that the first to third locking devices 21 to 23 are locked to the first to third locked holes 12a to 12c by the operation of the gremon handle 14, it is turned on. The circuit 44 energizes the electromagnet 41 based on the detection output of the handle sensor 39. As a result, the electromagnet 41 adsorbs the object 37 to be adsorbed by its magnetic force, so that the door 11 is locked. Thereafter, even if a large force is applied to the handle 14 in an attempt to operate the glemon handle 14, the handle 14 does not move. Further, since the locking parts such as the electromagnet 41 and the motion conversion mechanism 38 are robust, these parts are not damaged.

However, the release means may be constituted by a release knob or a release key cylinder attached to the door and a sensor for detecting these movements. Good. In this case, the movement of the release knob or release key cylinder is detected by a sensor, and the detection output of this sensor is connected to the control input of the control circuit.

  In the above embodiment, the lever / pin mechanism is used as the motion conversion mechanism, but a motion conversion mechanism such as a cam mechanism, a pinion rack mechanism, or a link mechanism may be used. When a cam mechanism is used as the motion converting mechanism, as shown in FIG. 11, the motion converting mechanism 78 of the handle lock means 76 includes a cam 86 having a base end fitted to the upper shaft 24 and an adsorbent on the upper surface. 37, and a movable body 87 that can move up and down in the case 83, and a pair of engaging pins 88 and 88 that are provided on the movable body 87 at a predetermined interval in the vertical direction and loosely fit the cam 86. . Inside the case 83, a plurality of guide pins 83 a are attached in two rows at predetermined intervals in the vertical direction while maintaining a width narrower than the width of the moving body 87.

When a pinion / rack mechanism is used as the motion conversion mechanism, a pinion is fitted into the upper shaft, and an electromagnet is attached to a rack that is engaged with the pinion and is movable up and down. This pinion rack mechanism is configured such that when the upper shaft rotates, the pinion rotates, and the rotational motion of the pinion is converted into the linear motion of the rack so that the electromagnet moves up and down.
When a link mechanism is used as the motion conversion mechanism, the base end of the first link is fitted to the upper shaft, the base end of the second link is attached to the vertically movable electromagnet, the tip end of the first link and the second link The tip of the link is connected. That is, this link mechanism is a mechanism that approximates a mechanism that converts the rotational motion of the crankshaft of the engine into the linear motion of the piston. In this link mechanism, when the upper shaft rotates, the first link rotates, and the rotational motion of the first link is converted into the linear motion of the base end of the second link, so that the electromagnet moves up and down.
