  Hereinafter, the present invention will be described in more detail with reference to the example of the drawings. A is a door that can be opened and closed in both directions, and is a door that can be opened and closed in the present example. The column 10 includes a column 10 and a column on the suspension base (not shown), and a door body 20 suspended and supported on the column on the suspension side. The suspension support of the door body 20 with respect to the column on the suspension side includes the door body. It is made of an aluminum extruded material, which is performed at 20 center positions in the thickness direction.

  At this time, the one-way gate A is always urged and projected toward the door 20 side of the door body 20 so that the door body 20 can be held in a sandwiched manner, and the door body 20 can be closed by turning the door. A catcher 30 provided with a pair of inner and outer protruding and retracting members 33 that allow individual press immersion and disposed on the column 10 on the door end side, and the door body 20 from the door end in conjunction with the operation of the handle 45 of the door body 20 A pusher 40 provided with a pair of inner and outer pressing members 43 that can simultaneously press and retract the pair of inner and outer projecting and retracting members 33 in the catcher 30 by projecting simultaneously, and disposed on the door body 20 door side. In this example, the catcher 30 and the pusher 40 are respectively provided with a pair of housings 31 and 41 for fixing them to the support column 10 on the door-end side or the inner and outer surfaces of the door body 20, and the housing. 31 and 41, and the pair of inner and outer pressing members 43 in the pusher 40 are always moved in the immersive direction by the return direction biasing force of the handle 45. Energized.

  In this example, the catcher 30 and the pusher 40 are each a pair of the inner and outer housings 31 and 41 that are individually installed with respect to the surface to be found, and the projecting and retracting member 33 arranged in the housings 31 and 41. The pressing member 43 is provided. At this time, the pair of housings 31 of the catcher 30 of this example are provided with storage portions 32 that open to the door end side and also serve as slide guides of the projecting and retracting members 33, and each of the back surfaces is a contact surface, for example, screws The attachment surface is brought into contact with the internal and external surface of the door column 10 by appropriate fixing means, and the attachment is fixed. The housing 31 is arranged at the same position in the height direction and the inside / outside direction of the column 10 on the door end side.

  The protrusion member 33 in the catcher 30 of this example is a latch bolt, and the taper surface thereof is arranged outward in the inner / outer direction so that the individual immersion by the door contact of the door body 20 closing rotation is performed. The inside of the door body 20 is used as the holding portion 34 of the 20 door ends. That is, the latch bolt is a commercially available latch lock and is housed in the housing portion 32 of the housing 31 so that the opening serves as a projecting and retracting guide. From the housing 31, the taper surface is exposed to the outside in the inner and outer directions, and the holding portion 34 that holds the door body finding surface in a sandwiched manner always protrudes toward the door end side of the door body 20 so as to face the inner side in the inner and outer directions. It is energized to do.

  The catcher 30 is attached and fixed so that the housing 31 containing the projecting member 33 is placed on the inner and outer finding surfaces of the column 10 on the door-end side so that the inner and outer positions of the column 31 are in the same height direction. In this case, the post 10 on the door-end side in this example has a cross-sectional shape that is convex, and the middle of the expected surface on the door body 20 side is partly on the door body side. A receiving step portion is formed by protruding the intermediate protrusion 11 having the same expected width as the door body 20 or a slightly wider width than the door body 20, and each housing 31 is disposed on the receiving step portion, This prevents the housing 31 from projecting inward and outward from the support column 10 and impairs its appearance, and reduces the dimensional difference in the expected direction between the support column 10 having a wide expected surface and the door body 20 having a narrow expected surface. By absorbing , The protruding and retracting member 33 are then adapted to contain a finding surface of door 20 door leading to the clamping shape.

  On the other hand, the pair of housings 41 in the pusher 40 of the present example is provided with a storage portion 42 that opens to the column 10 side of the door end side and also serves as a slide guide for the pressing member 43, and the back surface of each of the housings 41 is the contact surface. In the same manner, the contact surface is brought into contact with each of the contact surfaces of the door body 20, for example, the inside and outside of the vertical fence 21 by appropriate fixing means such as screws, and the attachment is fixed. The fixing is carried out so that the same position is formed in the height direction and the inside and outside direction of the vertical rod 21 and the position of the pressing member 43 is aligned with the height position of the projecting and retracting member 33 of the catcher 30. The housing 41 in this example also serves as a pair of inner and outer handle fixing plates that fix the handle 45 to the door body 20, and a storage portion 42 is formed in the handle fixing plate, and the pressing member 43 is stored in the storage portion 42. Thus, the complexity of the appearance due to the further arrangement of the housing in addition to the handle fixing plate is eliminated, and the interlocking of the pressing member 43 with the operation of the handle 45 can be made as simple as possible.

  That is, in this example, the handle 45 is a lever handle, and the lever handle is attached to a handle fixing plate installed on, for example, the door body 20 or the vertical shaft 21 in this example, on the rotation shaft. 46 is rotatably supported, and a pair of inner and outer lever handles 45 are fixed to both inner and outer ends of the rotating shaft 46. At this time, the lever handles 45 are latched protruding from the handle fixing plate and the rotating shaft 46. It is energized by inserting a compression spring 44 between the flange 47 and the horizontal arrangement so as to be normal to the longitudinal direction of the longitudinal rod 21 so that the lever handle 45 is rotated downward. By moving and opening the door body 20, the pair of inner and outer pressing members 43 are simultaneously projected from the housing 41, while the hand 45 is released. Thus, the compression spring 44 returns to the normal state of horizontal arrangement. At this time, the link of the pressing member 43 to the operation of the handle 45 is performed between the rotating shaft 46 and the rear end of the pressing member 43 by a link bar. 48, and the link bar 48 converts the rotational movement of the rotary shaft 46 due to the opening operation of the lever handle 45 into the linear movement of the pressing member 43. The pressing member 43 is drawn in the opposite direction by the urging force of the lever handle 45 in the return direction by the compression spring 44 when the lever handle 45 is released after the opening operation, so that the pressing member 43 is retracted into the housing 41. It is.

  The pair of inner and outer pressing members 43 in the pusher 40 of the present example is made of, for example, a metal plate member disposed on both the inner and outer finding surfaces of the door 20 and in the present example. The pressing member 43 is accommodated in the accommodating portion of the housing 41 so as to be positioned below the pivotal support position of the rotation shaft 46 of the lever handle 45 in the handle fixing plate.

  The gate A of this example formed in this way is provided with a catcher 30 disposed on the above-mentioned support-side column 10 and a pusher 40 disposed on the door body 20 as a lock of the gate body 20. When the door is closed, the projecting and retracting member 33 of the catcher 30, in this example, the holding portion 34 inside the inside and outside of the latch bolt, holds the inside / outside surface of the vertical rod 21 of the door body 20 in a sandwiched manner. Thus, while the door body 20 is maintained in the closed and locked state, the pressing member 43 protruding from the pusher 40 by the opening operation of the lever handle 45 simultaneously presses and sinks the latch bolt of the catcher 40, and the door body 20 The previous holding is released, and the door 20 is opened by setting the locked state to the unlocked state. Further, if the opened door body 20 is pushed in the closing direction and the door body 20 is rotated and closed, the door body 20 has a door tip on the protruding and retracting member 33 on one side of the catcher 30, and the taper surface of the latch bolt in this example. Contacting the latch bolts individually, forcibly immersing them, and using the above-mentioned holding part of the other projecting and squeezing member 33 as a door stop stopper, By hitting, the pair of projecting and retracting members 33 inside and outside the catcher 30 can hold the door body 20 and the door body 20 is closed.

  In other words, the door 20 held by the catcher 30 is pushed simultaneously with the opening operation of the lever handle 45, and the pressing member 43 of the pusher 40 simultaneously presses the latch bolts that can be protruded and retracted in pairs inside and outside the catcher 30. Then, as a result of immersing the latch bolt, during the opening operation, the holding of the door body 20 is released simultaneously in both the inside and outside directions. , For example, if it rotates in the push-open direction, the latch bolt of the catcher 30 and the position of the pressing member 43 of the pusher 40 are displaced, and the latch bolt on the non-rotating side, that is, the front side is driven by the biasing force. The latch bolt on the other side of the rotation side, that is, the push-open side, slides in contact with the door end of the door body 20, in particular, the prospective surface, and the door end 20 door ends. If until passes them completely through the door 20 the door head with a state that immersive is this leads to protrude by the biasing force likewise.

  Accordingly, when the door body 20 is opened, the pair of inner and outer latch bolts of the catcher 30 are protruded by the urging force. When the door body 20 is closed, the door body 20 door tip rotates. However, as a result of coming into contact with the tapered surface of one latch bolt in the inner and outer direction, the latch bolt with which the door body 20 contacted, that is, the other latch bolt on the rotating side is pressed against the door body 20 door tip. Forcibly immerse and allow the door 20 to pass through, while the other latch bolt in the inner and outer direction, that is, one latch bolt on the non-rotating side is in a state of protruding by its urging force. The holding part 34 serves as a door stop stopper, receives the door 20 door tip, and when one of the holding surfaces reaches a fixed position and the door 20 door passes, it is pressed and forced. Immersive Tchiboruto result that protrudes by the urging force, in a state of being held so as to clamp again door 20 door head at its finding surface.

  For this reason, unlocking operation by a handle operation, opening of the door body 20 toward the inside or outside by pushing-opening at the time of unlocking, and locking operation by simple closing operation such as pushing the door body 20 after entering and exiting It is possible to automatically close the door body 20 without making it possible to enter and exit as easily as possible, and to improve usability. Also, the pair of inner and outer protruding members 33, that is, the latches are not protruded by the handle operation, and the holding portion 34 always protrudes as a door stopper, so that, for example, the handle operation state, that is, the lever handle 45 is lowered. Even if an inadvertent handle operation such as closing the door body 20 in the unlocked state is performed, the door body 20 can always be securely closed, and thus the conventional gate door in which the handle operation and the protrusion and depression of the latch are interlocked. As you can see, it eliminates the danger that the door will pass through the latch receiver and the door will pop out and hit the passerby or the handle operator will fall over. It is possible to ensure a high degree of sex.

In the figure, reference numeral 12 denotes a housing 31 of the catcher 30 arranged on the post 10 on the door-end side. The nut 31 is fixed to be slidable up and down by a screw (not shown) to fix the housing 31 so that the height of the post 31 can be adjusted. The nut receiving groove 22 to be used in this example smoothly performs door-end contact of the door body 20 closing rotation with respect to the projecting and retracting member 33 of the catcher 30 and prevents damage due to contact of the door body 20 door-end. In addition to the catcher 30 and the pusher 40 in the present example, a sliding plate 49 for sliding the projecting member disposed at the position corresponding to the projecting member 33 at the door end of the door body 20 includes, for example, By a manual operation, it is arranged so as to be slidably engageable with a receiving hole arranged in the inner housing 41 of the pusher 40 from the inner housing 31 of the catcher 30. It shows a deadbolt lock which is adapted to be without the locking of the additionally inner operated by.

  The example shown in the figure is as described above. In addition to the above gate doors, the above structure is applied to doors with frames such as entrance doors and indoor doors, a catcher is placed on one open door, and a pusher is placed on the other open door By applying the above structure to a double door, and by installing the catcher in a frame or a column on the door end side, for example, the projecting member can be arranged to project freely on the expected surface, The protrusion / holding member is used to hold the door body door, the catcher and / or the pusher are arranged on the inner / outer integrated housing, respectively, and the inner operation lock is additionally provided. Use appropriate locks, including inner locks, and those equipped with the above catchers and pushers as door locks that can be opened and closed in both directions.
