Description

    The present invention relates to a panel-shaped shielding means combined with an opening of a building, that is, a door unit comprising a door or a door of a window (herein, these are collectively referred to as “door”) and a frame for accommodating them. .

    The door is provided with a lock to keep it closed. In the case of a door, a structure is generally provided in which a hook-shaped dead bolt is provided at the free end thereof, and the dead bolt is protruded from the door by turning a key and engaged with a receiving portion on the door frame side. FIG. 6 shows the structure of such a door. FIG. 6 is a schematic plan view, in which 101 is a door frame and 102 is a door. One end of the door 102 is connected to the door frame 101 by a hinge portion 103 and opens and closes using the hinge portion 103 as a fulcrum. A dead bolt 104 enters and exits from the free end of the door 102. If the dead bolt 104 is engaged with the receiving portion on the door frame 101 side, the door 102 does not open.

    In the case of a door having a general structure as described above, the lock location is clear and the area is easily attacked intensively. It is also easy to insert the tip of a bar into the gap between the door frame 101 and the door 102 and forcibly open it using the lever principle.

In order to cope with the above problem, in the door described in Patent Document 1, a guard piece is formed at the door end to close the gap between the door and the door frame, and a bar is inserted into the gap to open the door. Is preventing.
JP 2003-138849 A (page 2-4, FIG. 1-10)

    The door described in Patent Document 1 is resistant to attacks by crowbars. However, when a tool other than a bar, such as a drill, is used in combination, the deadbolt is exposed, and there is a possibility that it will be attacked intensively and eventually the locking part will be destroyed. .

    The present invention has been made in view of the above points, and proposes a robust door unit that is strong against an attack by a drill or a bar.

    (1) In the present invention, in a door unit that includes a door frame and a door that is accommodated in the door frame and that opens and closes with one end as a fulcrum, the free end of the door and the side of the door frame corresponding to the free end And a hinge portion that connects the fulcrum side end of the door to the door frame to shift the door in a direction in which the stamp stamp fitting portion achieves stamp stamp fitting. Is possible.

    (2) In the door unit having the above-described structure, the hinge portion includes a door-side fulcrum shaft, a door frame-side fulcrum shaft, and a relay plate that connects these fulcrum shafts.

    (3) In the door unit having the above structure, the hinge portion is provided with both the door side fulcrum shaft and the door frame side fulcrum shaft on the same side of the indoor side or the outdoor side.

    (4) In the door unit having the structure described above, one of the door-side fulcrum shaft and the door frame-side fulcrum shaft is provided on the indoor side and the other is provided on the outdoor side.

    (5) In the door unit having the above structure, the hinge portion holds the door slidably.

    (6) Moreover, in this invention, in the door unit provided with the door frame and the door accommodated in this door frame, and opened and closed with one end as a fulcrum, the free end of the door and the door frame corresponding to the free end A hinge portion that forms a stamping fitting portion between the side and a hinge portion that connects the fulcrum side end of the door to the door frame shifts the door in a direction in which the stamping fitting portion achieves the stamping fitting. The hinge portion includes a door-side fulcrum shaft and a door frame-side fulcrum shaft provided on the same side of the indoor side or the outdoor side, and a relay plate that connects these fulcrum shafts. Combined with these doors and door frames is an automatic opening and closing device formed by connecting a first link connected to the door and a second link fixed to the output shaft of the motor provided on the door frame side. In addition, the motor has a connection point between the first link and the second link. It is assumed that can cause beyond the extension on the first link and the door and a line connecting point between connecting said output shaft of.

    (1) An indicia fitting part is formed between the free end of the door and the side of the door frame corresponding to the free end, and the indicia is fitted by a hinge part that connects the fulcrum side end of the door to the door frame. Since the door is shifted in the direction that achieves the seal fitting, if the stamp fitting part is formed over the entire height of the door, the door will not be attacked unless the entire door height is attacked. You will not be able to open it, and the resistance to attacks will increase dramatically due to crowbars.

    Further, in the case of the door described in Patent Document 1, since the guard piece is provided on the door side, it is difficult to give the strength that the guard piece is not turned up due to restrictions on the thickness of the guard piece. On the other hand, in the present invention, reinforcement measures such as increasing the thickness of the wall portion of the stamp fitting portion are relatively easy, and the stamp fitting portion can have sufficient strength.

Therefore, the door unit of the present invention can be easily realized.

    (3) Since both the door side fulcrum shaft and the door frame side fulcrum shaft are provided on the same side of the indoor side or the outdoor side, the hinge portion prevents the hinge portion from being bent, and the door and the relay plate are arranged in a straight line. This will prevent the door from being shifted and opened.

    (4) Since the hinge portion has one of the door side fulcrum shaft and the door frame side fulcrum shaft provided on the indoor side and the other provided on the outdoor side, the door can be provided as long as the door does not shift. Can be prevented from opening.

    (5) Since the hinge portion holds the door in a slidable manner, the door can be prevented from opening as long as the door is prevented from sliding.

    (6) An imprint fitting part is formed between the free end of the door and the side of the door frame corresponding to the free end, and the imprint fitting is performed by a hinge part that connects the fulcrum side end of the door to the door frame. Since the door is shifted in the direction that achieves the seal fitting, if the stamp fitting part is formed over the entire height of the door, the door will not be attacked unless the entire door height is attacked. You will not be able to open it, and the resistance to attacks will increase dramatically due to crowbars. The hinge portion is provided with a door-side fulcrum shaft and a door frame-side fulcrum shaft provided on the same side of the indoor side or the outdoor side, and a relay plate that connects these fulcrum shafts. Combined with the door frame is an automatic opening and closing device that connects the first link connected to the door and the second link fixed to the output shaft of the motor provided on the door frame side. By making the connecting point of the first link and the second link exceed the extension of the line connecting the connecting point of the first link and the door and the output shaft, the automatic opening / closing device It will also function.

    A first embodiment of the present invention will be described below with reference to FIGS. Here, a door for a doorway of a house is presented as an example of a door. 1 (a), (b) and (c) are schematic plan views showing different states, and FIGS. 2 (a) and (b) are schematic front views showing different states. is there.

    A door 20 is attached to the door frame 10 on the right side as viewed from the front. It is the hinge portion 30 that attaches the door 20 to the door frame 10. The hinge portion 30 includes a door side fulcrum shaft 31 and a door frame side fulcrum shaft 32, and has a structure in which both fulcrum shafts are connected by a relay plate 33. The door-side fulcrum shaft 31 is placed at a position flush with or close to the outdoor side surface of the door 20, and the door frame-side fulcrum shaft 32 is also placed outside the door so as to be aligned with the door-side fulcrum shaft 31. Moreover, the hinge part 30 has the length which covers the full height of the door 20 (refer FIG. 2).

    The door 20 has a free end 20 a at the end opposite to the end connected to the hinge portion 30. A stamp fitting portion 40 is formed between the free end 20a and the side of the door frame 10 corresponding thereto. The stamp fitting part 40 has a shape in which the vertical groove 11 formed on the inner surface of the door frame 10 receives the free end 20 a of the door 20. The seal stamp fitting portion 40 also covers the entire height of the door 20.

    The door frame 10 is formed with an overhang portion 12 that extends toward the hinge portion 30 on the outdoor side near the upper end and the lower end of the stamp fitting portion 40. On the other hand, on the side of the hinge portion 30, an overhang portion 13 is formed on the indoor side so as to face the inner surface of the hinge portion 30. The overhanging portion 13 extends to a position where it can receive the end of the door 20 in the closed state.

    FIG. 1A shows a state where the door 20 is closed. In order to open the door 20 from this state, the free end 20a of the door 20 must first be taken out from the stamp fitting portion 40. In order to take out the free end 20a of the door 20 from the stamp fitting part 40, it is necessary to bend the hinge part 30 and shift the door 20 to the right in the figure as shown in FIG. Then, after waiting for the free end 20a of the door 20 not to be caught by the overhanging portion 12, the door 20 is opened as shown in FIG.

    When the door 20 is closed, the door 20 is shifted leftward from the position shown in FIG. When the door side fulcrum shaft 31, the relay plate 33, and the door frame side fulcrum shaft 32 are aligned with the door 20, the door 20 is completely closed.

    As can be seen from this movement, the door 20 is not opened unless the door 20 is shifted from the state of FIG. As shown in FIG. 1A, if the door side fulcrum shaft 31, the relay plate 33, and the door frame side fulcrum shaft 32 are aligned with the door 20, the door 20 does not shift. If a lock device that prevents the shaft 31 from being pulled out to the outdoor side is provided, the door 20 can be locked.

    In the locked state, the bar cannot be inserted into the gap between the door frame 10 and the free end 20 a of the door 20. Even if it is considered to forcibly bend the portion of the door frame 10 that forms the stamp fitting portion 40, the operation must be performed over the entire height of the door 20, and is extremely difficult. The difficulty can be further increased by increasing the thickness of the door frame 10 so that the door frame 10 is bent.

    Even if the target of the attack is directed to the hinge part 30, it is difficult to narrow down the target of the attack with the hinge part 30 that exists over the entire height of the door 20. It is also difficult to destroy the hinge portion 30 over the entire height of the door 20. Therefore, the hinge part 30 is also difficult to become an attack target. As a result, the door unit of the first embodiment is extremely robust against attacks from the outside.

    If the shift of the door 20 can be locked in the state shown in FIG. 1B, the outsider can be confirmed by looking through the gap between the free end 20a of the door 20 and the door frame 10. That is, the same function as a door guard with a normal door chain is performed. FIG. 2B is a view of this state from the outdoor side.

    Next, a second embodiment of the present invention will be described based on FIGS. 3 (a), (b), and (c). FIGS. 3A, 3B, and 3C are schematic plan views of the door, and show different states. In addition, the same code | symbol as before is attached | subjected to the same component as 1st Embodiment, or the same function, and description is abbreviate | omitted. The same principle is applied to the third embodiment and subsequent embodiments, and the same components as those described above are denoted by the same reference numerals and the description thereof is omitted.

    The second embodiment is a partial modification of the first embodiment, and the structure of the hinge portion 30 is different from that of the first embodiment. That is, in the first embodiment, both the door-side fulcrum shaft 31 and the door frame-side fulcrum shaft 32 are provided on the outdoor side, whereas in the second embodiment, the door-side fulcrum shaft 31 is provided on the outdoor side. The door frame side fulcrum shaft 32 is provided on the indoor side.

    In order to open the door 20 from the state of FIG. 3A, the door 20 is shifted to the right in the figure as shown in FIG. Then, after waiting for the free end 20a of the door 20 not to be caught by the overhanging portion 12, the door 20 is opened as shown in FIG.

    In this structure, if a lock device that prevents the door 20 from shifting is provided, the door 20 can be locked.

    Next, a third embodiment of the present invention will be described based on FIGS. 4 (a), (b), and (c). 4A, 4B, and 4C are schematic plan views of the door, and show different states.

    The hinge portion 35 of the third embodiment has a sheath shape, and the end of the door 20 is slidably held therein.

    In order to open the door 20 from the state of FIG. 4A, the door 20 is slid rightward in the drawing as shown in FIG. 4B. Then, after waiting for the free end 20a of the door 20 not to be caught by the overhanging portion 12, the door 20 is opened as shown in FIG.

    In this structure, if a lock device is provided to prevent the door 20 from sliding in the hinge portion 35, the door 20 can be locked.

    Next, a fourth embodiment of the present invention will be described based on FIGS. 5 (a) and 5 (b). 5 (a) and 5 (b) are schematic plan views of the door, showing different states.

    In the fourth embodiment, the automatic opening / closing device 50 is combined with the door 20 of the first embodiment. The automatic opening / closing device 50 includes a first link 51 attached to the door 20, a motor 52 supported on the door frame 10 by an attachment member (not shown), and one end fixed to the output shaft 53 of the motor 52. The other end is a second link 54 connected to the tip of the first link 51. The output shaft 53 may be an output shaft of a speed reducer built in the motor 52, or may be an output shaft of a speed reducer separate from the motor 52.

    When the motor 52 rotates the second link 54 in the direction of the arrow in FIG. 5A, the door 20 shifts in the closing direction. The connection point 55 between the first link 51 and the second link 54 is an extension of the line connecting the connection point between the first link 51 and the door 20 and the output shaft 53, that is, the line A in FIG. , The free end 20a of the door 20 completes the fitting of the door frame 10 to the vertical groove 11. The motor 52 does not stop rotating here and continues rotating until the connecting point 55 slightly exceeds the line A. A stopper 56 fixed to the door frame 10 receives the first link 51 that has crossed the line A.

    According to this configuration, the force for pulling out the door-side fulcrum shaft 31 of the hinge portion 30 acts on the outside in the direction that inhibits the connecting point 55 from crossing the line A in the reverse direction. That is, the presence of the automatic opening / closing device 50 itself functions as a lock mechanism for the door 20. Since a large force is not necessary to keep the door-side fulcrum shaft 31 from being pulled out to the outdoor side, this lock mechanism can sufficiently function as a lock.

    The lock mechanism using the automatic opening / closing device as described above can be applied to a normal door attached to a door frame with a normal hinge.

    While the embodiments of the present invention have been described above, various modifications can be made without departing from the spirit of the invention.

    The present invention can be widely used in buildings as a robust door unit that is resistant to external attacks.
