Description

  The present invention relates to a joinery, and more specifically, a lock device that locks a face material supported to be freely opened and closed by a frame, an opening angle regulating device that regulates an opening angle of the face material, and the face material from the outdoor side in an emergency. The present invention relates to a joinery provided with an external opening device for opening the door.

  Conventionally, as a fitting such as a casement window or a vertical window, the opening angle of the shoji (face material) is controlled by a regulation means such as a stay, so that the ventilation window is configured to be ventilated in this half-open state. It's being used. In such a ventilation window, the gap between the window frame (frame body) and the shoji is made small in a half-open state in a normal state, specifically, so that only a gap that does not allow humans to pass (for example, about 10 cm) can be made. By doing so, safety can be secured. On the other hand, in the event of an emergency such as a fire, if a fire brigade tries to enter the indoor side from the outdoor side, it cannot enter unless the shoji is opened to the half open state. A ventilation stay is proposed (see, for example, Patent Document 1), and the shoji can be fully opened from the outdoor side by operating this outdoor knob.

JP 2001-288949 A

  By the way, a normal window is provided with a locking device for locking the shoji. In order to open the shoji from the outdoor side in the ventilation window, the locking device is unlocked and the outdoor knob is operated. It is necessary to fully open the shoji after releasing the restriction on the opening angle. For this reason, since at least two steps of unlocking operation and deregulation operation are required, there is a disadvantage that the procedure for fully opening the shoji becomes complicated.

  An object of the present invention is to provide a joinery that can be quickly fully opened by an easy operation from the outdoor side in an emergency even if it is a face material whose opening angle is normally restricted.

  The joinery of the present invention includes a frame provided in a building opening, a face member supported by the frame so as to be opened and closed, a lock device that locks and unlocks the face member with respect to the frame, and the frame. A door opening angle restricting device for restricting the opening angle of the face material, and an external opening device for releasing the face material from the outdoor side in an emergency, wherein the locking device includes the frame A lock operating portion provided on one of the body and the face material and operable from the indoor side; a lock engaging portion that moves between a lock position and an unlock position in conjunction with the lock operation portion; and the frame body And a lock receiving portion that is provided on the other of the face materials and can be engaged with the lock engaging portion, and the opening angle regulating device is provided on one of the frame body and the face material. An angle regulating arm whose one end is rotatably supported, and the other of the frame body and the face material, A restriction receiving portion engageable with the other end side of the degree restriction arm, and restriction switching means capable of switching between restriction and release on the other end side of the angle restriction arm by the restriction receiving portion, The external opening device includes an outdoor operation unit that is provided on one of the frame body and the face material and can be operated from the outdoor side, and a first interlocking unit that interlocks the outdoor operation unit and the lock engaging unit. And a second interlocking portion that interlocks the outdoor operation portion and the restriction switching means, and the lock engaging portion is unlocked by an opening operation of the lock operation portion of the lock device in a normal state. The face member can be opened by being moved to a position, and the other end side of the angle restricting arm of the opening angle restricting device is engaged with the restriction receiving portion, whereby the opening angle of the face member is restricted. In an emergency, the outdoor operation of the external opening device The unlocking operation moves the lock engaging portion to the unlocked position via the first interlocking portion, and operates the restriction switching means via the second interlocking portion to move the angle restricting arm and the like. The face material is configured to be fully openable by switching the restriction on the end side to the release side.

  According to the present invention, the first interlocking unit and the second interlocking unit are interlocked with the operation of the outdoor operation unit, the locking device is unlocked by the first interlocking unit, and the opening angle is restricted by the second interlocking unit. Since the restriction of the device is released, in the event of an emergency, the face material can be fully opened quickly with a simple operation of simply operating the outdoor operation unit. On the other hand, in normal times, the opening angle of the face material is regulated by the opening angle regulating device, so that the fitting can be used as a ventilation window.

It is preferable that the other end side of the angle regulating arm is regulated by the regulation receiving portion by being biased and the other end side of the angle regulating arm moving to the regulation receiving portion side.
According to such a configuration, the restriction or release of the other end of the angle restriction arm with respect to the restriction receiving portion is switched by sliding the slide member, that is, the restriction switching means is arranged on one end side of the angle restriction arm. The structure of the restriction receiving portion on the end side can be made relatively simple. Further, by urging the slide member by the urging means, the slide member is automatically returned to the initial position along with the closing operation by simply closing the outdoor operation portion after closing the face material. The other end side of the restriction arm can be restricted by the restriction receiving portion. Therefore, when the face material is closed after being fully opened and returned to the normal use state, the restriction by the angle restricting arm can be made effective, and it is not necessary to manually return the angle restricting arm, thereby preventing forgetting to restrict. It is possible to reliably maintain the open angle regulation state of the face material in the normal state.

In the fitting of the present invention, the restriction receiving portion of the opening angle restriction device has a restriction guide groove that slides and guides the other end side of the angle restriction arm, and the restriction switching means is one end of the restriction guide groove. A closing member movable between a position for closing the opening and a position for opening the opening, and a biasing means for biasing the closing member toward the closing side. By moving the closing member to the open side via the second interlocking portion, the other end side of the angle restricting arm is released from the restricting guide groove, and the restriction is released. It is preferable that the other end side of the angle regulation arm is inserted into the regulation guide groove and regulated by being biased by the biasing means and being moved to the closing side by the closing operation of the portion. .
According to such a configuration, the regulation guide groove of the regulation receiving part is closed or opened by the closing member to switch the regulation or release of the other end side of the angle regulation arm, that is, the regulation switching means is switched to the regulation receiving part side. By disposing in this way, the structure on one end side of the angle regulating arm can be made relatively simple. Further, by urging the closing member to the closing side by the urging means, the closing member is automatically moved along with the closing operation only by closing the outdoor operation portion after closing the face material. The other end side of the angle regulating arm can be regulated by closing one end of the angle regulating arm. Therefore, when the face material is closed after being fully opened and returned to the normal use state, the restriction by the angle restricting arm can be made effective, and it is not necessary to manually return the angle restricting arm, thereby preventing forgetting to restrict. It is possible to reliably maintain the open angle regulation state of the face material in the normal state.

In the above, in the joinery of the present invention, the lock operation portion and the lock engagement portion in the lock device are provided in the face material, and the lock receiving portion is provided in the frame body, One end side of the angle restricting arm is rotatably supported by the face material, the restricting receiving part is provided on the frame body, and the outdoor operation part, the first interlocking part and the second interlocking part of the external opening device. The parts are preferably provided on the face material.
According to such a configuration, the lock operation portion and the lock engagement portion of the lock device, the one end side of the angle regulating arm, the outdoor operation portion of the external opening device, the first interlocking portion and the second interlocking portion are provided on the face material. As a result, the structure for interlocking these parts can be configured relatively easily, and the parts can be reliably interlocked. In other words, when the members that are interlocked with each other are arranged separately in the face material and the frame, the mechanism for interlocking them becomes complicated and it is necessary to cope with the opening and closing of the face material, By being arranged, each part can be reliably interlocked with a simple structure. In addition, by providing a lock operation part and outdoor operation part on the face material side, handles for opening and closing the face material can be included in these operation parts, compared to the case where a separate opening / closing handle is provided. The number of points can be reduced, and the operability of the opening / closing operation and the design of the joinery can be improved.

Then, as shown in FIGS. 5 and 9C, when the second connecting member 36 is lowered, the interlocking protrusion 244 is pushed down by the interlocking engagement portion 361, and the slide member 24 is lowered. As the slide member 24 is lowered, the engaged pin 253 of the angle restricting arm 25 is detached from the receiving member 22 as described above, and the restriction on the opening angle of the shoji 4 is released.

  According to the external opening device 30 as described above, in the event of an emergency such as a fire, only the opening of the outdoor handle 31 unlocks the gremon lock 10 via the first connecting member 35 and the second connecting member. The restriction of the angle restriction arm 25 of the half-opening device 20 is released via 36, and the shoji 4 can be fully opened by pulling the outdoor handle 31 to the outdoor side in this state. If the outdoor handle 31 is returned to the indoor side after closing the shoji 4, the second connecting member 36 moves upward, so that the depression of the interlocking protrusion 244 by the interlocking engagement portion 361 is released, and the coil spring 27 is released. Due to the urging force, the slide member 24 returns to the upper initial position. As a result, the engaged pin 253 of the angle restricting arm 25 is inserted into the guide groove 281 from the opening 282 of the receiving member 22, and the angle restricting arm 25 is restricted by the receiving member 22, whereby the opening angle of the shoji 4 is changed.
