Description

  The present invention relates to a joinery having a function to suppress the opening of shoji in a fire or the like.

2. Description of the Related Art Conventionally, as a fitting, an externally-turned window including a window frame, a shoji, and a door lock mechanism that holds the door in a closed position at the time of a fire is known (see Patent Document 1). The door lock mechanism has a base fixed to the shoji, a movable locking body supported by the base, a torsion coil spring that urges the movable locking body in a standing direction, and holds the movable locking body in a standby posture. And a stopper. The movable locking body is freely swingable between the standby posture and the standing posture, and can be locked with the window frame in the standing posture. The stopper is made of rigid resin or fuse metal having lower heat resistance than the base body, the movable locking body, and the torsion coil spring.
In this case, when the ambient temperature rises in the event of a fire, the stopper softens and the holding state of the movable latching body is released, and the movable latching body is oscillated while being urged by the torsion coil spring until it assumes a standing posture. It moves and is locked to the window frame. Thereby, the shoji is locked to the window frame, and the closed door posture is maintained.

JP-A-4-266671

By the way, in the external fall window described in Patent Document 1, the door lock mechanism is constituted by a base body, a movable locking body, a torsion coil spring, and a stopper, and is particularly locked to the window frame. Since the movable locking body is constituted by a separate member from the torsion coil spring, the number of parts is large, and it is difficult to simplify the configuration and reduce the manufacturing cost.
Although it is possible to use a temperature sensing type sensor (such as a fuse latch) instead of softening the stopper to release the holding state of the movable locking body when the temperature rises, the sensor may malfunction. In addition, since the sensor itself is expensive, it is difficult to reduce the manufacturing cost.

  The objective of this invention is providing the fitting provided with the opening suppression function of the shoji which can simplify a structure and can reduce manufacturing cost.

  The joinery of the present invention includes a frame, a shoji attached to the frame so as to be openable and closable, and an opening restraining tool attached to one of the frame and the shoji, and the opening restraining tool includes the frame. An elastically deformable engaging member that engages the other of the body and the shoji, and a holding member that elastically deforms the engaging member and holds it in a non-engaged state with the other of the frame and the shoji The holding member releases the holding of the engaging member in the event of a fire, and the engaging member is restored by releasing the holding by the holding member and is out of the frame and the shoji It is possible to engage with the other of the two.

According to the joinery of the present invention, since the holding member elastically deforms the engaging member and holds it in a non-engaged state with the other of the frame and the shoji, the holding member holds the engaging member in the event of a fire. When the engagement member is released, the engagement member is restored, and the engagement member can be engaged with the other one of the frame body and the shoji to suppress the opening of the shoji. Thereby, it can suppress that the clearance gap between a frame and a shoji expands by the deformation | transformation by the temperature rise of a shoji, etc. and a big through-hole through which a flame etc. pass is formed.
Moreover, in the closing lock mechanism in the outside fall window of patent document 1, it is comprised by energizing a movable latching body with the torsion coil spring which is a different body from this, In the fitting of this invention Since the engaging member itself is positioned so as to be engageable with the other one of the frame and the shoji, it is not necessary to separately provide the above-described movable locking body and the torsion coil spring, and the number of parts can be reduced and the configuration can be reduced. Simplification can be achieved.

In the joinery of the present invention, the engaging member is attached to the shoji, the holding member is made of resin, and covers a holding portion that holds the engaging member in an elastically deformed state, and a corner of the shoji. It is preferable to have a cap portion.
According to such a structure, since a holding member has a cap part which covers the corner | angular part of a shoji, an opening suppression tool can be utilized as a resin cap which covers the corner | angular part of a shoji at normal times. On the other hand, in the event of a fire, the engaging member that is restored by being released from the holding by the holding member can be engaged with the other of the frame body and the shoji, and the opening of the shoji can be suppressed. As described above, the opening suppressor can exhibit two functions, that is, a function as a resin cap in a normal state and a function to suppress the opening of shoji in a fire.
In addition, it is not necessary to separately prepare a dedicated part for holding the engaging member and a cap part that covers the corner portion of the shoji, so that the configuration can be simplified and the workability can be improved. Furthermore, the existing equipment can be used effectively by exchanging the existing cap part with the opening restraint described above.

It is preferred that
According to such a configuration, the holding member holds the both end edges of the attachment piece and the engagement piece separated from the elastically deformable continuous portion. The restoring force of the leaf spring member that is constantly applied to the holding member can be reduced and the holding state of the leaf spring member can be stabilized as compared with the case where the holding portion is held at a position closer to the continuous portion.

In the joinery of the present invention, the holding member is made of resin, and includes a holding portion that holds the engaging member in an elastically deformed state, and a cap portion that covers a corner portion of the shoji. The joint member is constituted by a metal leaf spring member, and the leaf spring member is continuous to the attachment piece portion attached to the shoji, the elastically deformable continuous portion continuous to the attachment piece portion, and the continuous portion. And the holding portion holds both the attachment piece portion and the distal end edge portions of the engagement piece portion separated from the continuous portion in an elastically deformed state of the continuous portion. The front edge portion of the engagement piece is disposed at a position that can be engaged with the other of the frame and the shoji in a state where the holding by the holding portion is released, and the holding portion and the cap The portion is formed extending in a direction intersecting each other, In the attached state to the shoji, the holding portion is arranged to extend in the peripheral direction of the shoji, and the cap portion is arranged to extend in the prospective direction of the shoji so that the corner of the shoji Preferably, the mounting piece is screwed to the periphery of the shoji while the leaf spring member is held by the holding portion.
According to such a configuration, in a state where the opening restrainer is attached to the shoji, the holding portion is arranged to extend in the peripheral direction of the shoji, and the cap portion is arranged to extend in the expected direction of the shoji. Since the leaf spring member held by the holding portion and screwed to the peripheral edge of the shoji is held by the corner portion of the shoji, swinging such as rotation thereof is suppressed by the holding member. For this reason, it is not necessary to screw the leaf spring member with a plurality of screws, and the leaf spring member can be screwed with a single screw so that the leaf spring member cannot be swung, thereby improving workability.
Further, since the holding portion is arranged extending in the peripheral direction of the shoji and the cap portion is arranged extending in the prospective direction of the shoji, the holding member can be accurately positioned with respect to the shoji in two directions intersecting each other.

In the joinery of the present invention, it is preferable that a screw insertion hole is formed in the engagement piece portion, and the attachment piece portion is screwed to the shoji by a screw inserted from the screw insertion hole.
According to such a structure, a screw can be penetrated from the screw insertion hole of an engagement piece part, and an attachment piece part can be screwed to a shoji, and workability can be improved.

According to such a structure, since the front end edge of the attachment piece and the engagement piece is arranged on the opening direction side of the shoji with respect to the continuous portion, both ends of the continuous portion are in the restored state of the leaf spring member. Are located apart from each other, and both the end edge portions of the attachment piece and the engagement piece are wider than the continuous portion. For this reason, when the shoji is about to move in the opening direction, the engaging piece is engaged with the frame, and a force that is expanded to the side of the frame is applied, so that the shoji is caught between the frame and the shoji. The opening of the shoji can be more reliably suppressed.

In the joinery of the present invention, the frame body has an engaging portion that protrudes toward the shoji, and the engaging portion is configured so that an airtight material that comes into contact with the shoji can be attached when the shoji is closed. In addition, it is preferable that the engaging member is disposed at a position that can be engaged with the distal end edge portion in a state where the holding by the holding member is released.
According to such a configuration, the portion to which the airtight material is attached can be configured as an engagement portion with the opening suppressor, and the configuration can be simplified.

[Construction of opening restraint]
Hereinafter, the construction procedure of the opening restrainer 4A will be described.
First, the opening restraint tool 4A is assembled. Specifically, the leaf spring member 40 is elastically deformed so that the attachment piece portion 41 and the engagement piece portion 43 are close to each other, and the leading edge portions 414 and 431 are accommodated in the accommodation space 516 of the holding member 50. The engagement protrusions 412 are engaged with the engagement holes 515. As a result, the holding piece 511 holds the attachment piece 41 and the holding piece 512 holds the engagement piece 43. Here, since a force for restoring the original shape from the elastically deformed state is generated in the leaf spring member 40, the attachment piece portion 41 is in pressure contact with the holding piece portion 511, and the engagement piece portion 43 is in pressure contact with the holding piece portion 512. To do. For this reason, the engagement state between the engagement protrusion 412 and the engagement hole 515 is maintained, and the leaf spring member 40 does not fall off the holding member 50. Further, the leading edge portions 414 and 431 are in contact with the connecting piece portion 513, thereby suppressing swinging such as rotation while the leaf spring member 40 is held. In this way, the opening restraining tool 4A is assembled.
In the state where the leaf spring member 40 is held by the holding member 50, a slight gap is formed between the tip edge portions 414 and 431. For this reason, the leaf spring member 40 is elastically deformed, the attachment piece 41 is further brought closer to the engagement piece 43, and the engagement protrusion 412 is extracted from the engagement hole 515, whereby the leaf spring member 40 is removed from the holding member 50. It can also be removed.

Next, the opening restraint tool 4 </ b> A is attached to the vertical rod 33. Specifically, the holding piece portion 511 of the holding portion 51 is fitted between the protrusion 36A and the thick portion 37 in a state along the longitudinal direction of the vertical rod 33, and the step portion 521 of the cap portion 52 is expected to be the vertical rod 33. It contacts the upper end of the vertical rod 33 in a state along the direction. Subsequently, the screw 6 is inserted into the mounting hole 411 through the insertion hole 432 and is screwed into the screwing hole 371 so that the mounting piece 41 is brought into contact with the protrusion 36 </ b> B and the thick part 37. In this way, the opening restraining tool 4A is attached to the vertical rod 33.
In the attached state of the opening restraint tool 4 </ b> A, the cap portion 52 is disposed so as to cover the corner portion formed by the upper collar 31 and the vertical collar 33, and the respective leading edge portions 414, 431 of the leaf spring member 40 are from the continuous portion 42. Is also arranged outside the room.
In this way, the opening restraint tool 4A is constructed. The opening restraint tool 4B is also constructed in the same procedure as the opening restraint tool 4A.

[Operation of this embodiment]
Hereinafter, the operation | movement at the time of the fire of the vertical sliding window 1 which concerns on this embodiment is demonstrated.
For example, when a fire occurs on the outdoor side, the ambient temperature of the vertical sliding window 1 rises, and when the holding member 50 of the opening restraint tool 4A rises to 200 ° C. to 250 ° C., the holding member 50 softens. Based on this softening, the leaf spring member 40 in the disengaged state is not held by the holding portions 51 with respect to the respective leading edge portions 414 and 431, and the leaf spring member 40 is restored to its original shape as shown in FIG. At this time, the front end edge portion 431 of the engagement piece portion 43 is positioned facing the engagement portion 234 in the prospective direction of the vertical frame 23 and becomes in an engageable state. The holding member 50 reaches the melting point and melts and disappears due to further temperature rise.
When the shoji 3 moves in the opening direction due to warping of the shoji 3 due to further temperature rise, as shown in FIG. 10, the leading edge 431 of the engaging piece 43 is engaged with the engaging portion 234. And prevents the shoji 3 from opening.
In this way, the opening of the shoji 3 during a fire is suppressed. Note that the opening restraint tool 4B operates in the same manner as the opening restraint tool 4A.

[Effect of this embodiment]
(1) Since the holding member 50 elastically deforms and holds the leaf spring member 40 in a non-engaged state with the engaging portion 234, when the holding member 50 releases the holding of the leaf spring member 40 in the event of a fire, the leaf spring member While 40 is restored, the engagement portion 234 can be engaged and the opening of the shoji 3 is suppressed. Thereby, it can suppress that the clearance gap between the window frame 2 and the shoji 3 expands by the deformation | transformation by the temperature rise of the shoji 3, etc., and the big through-hole through which a flame etc. pass is formed.
Further, since the leaf spring member 40 itself is positioned so as to be engageable with the engaging portion 234, it is not necessary to provide a member that can be engaged with the engaging portion 234 in addition to the leaf spring member 40, and the number of parts can be reduced. The configuration can be simplified.
(2) Since the holding member 50 has the cap portion 52 that covers the corner portion of the shoji 3, the opening restrainers 4A and 4B can be used as a resin cap that covers the corner portion of the shoji 3 in normal times. On the other hand, in the event of a fire, the leaf spring member 40 that is restored by being released from being held by the holding member 50 can be engaged with the engaging portion 234, and the opening of the shoji 3 can be suppressed. In this manner, the opening restrainers 4A and 4B can exhibit the two functions of the function as a resin cap in normal times and the function of suppressing the opening of the shoji 3 during a fire.
In addition, it is not necessary to separately prepare a dedicated component for holding the leaf spring member 40 and a cap component that covers the corner portion of the shoji 3, and the configuration can be simplified and workability can be improved. Furthermore, the existing equipment can be used effectively by replacing the existing cap parts with the opening restrainers 4A and 4B described above.
(3) Since the holding member 50 holds both the front edge portions 414 and 431 of the attachment piece 41 and the engagement piece 43 separated from the elastically deformable continuous portion 42, for example, the attachment piece 41 and the engagement piece The restoring force of the leaf spring member 40 that is constantly applied to the holding member 50 can be reduced compared to the case where the leading end edge portions 414 and 431 of the portion 43 are held at a position closer to the continuous portion 42, and the holding state of the leaf spring member 40 can be reduced. Can be stabilized.
(4) When the opening restrainers 4A and 4B are attached to the shoji 3, the holding portion 51 extends in the direction along the vertical rod 33 (periphery direction of the shoji 3), and the cap portion 52 has the shoji. 3, the leaf spring member 40 held by the holding portion 51 and screwed to the vertical rod 33 is arranged so as to rotate and the like. Oscillation is suppressed by the holding member 50. For this reason, it is not necessary to screw the leaf spring member 40 with a plurality of screws, and the leaf spring member 40 can be screwed with a single screw 6 so that the plate spring member 40 cannot swing, thereby improving the workability.
In addition, since the holding portion 51 is arranged extending in the longitudinal direction of the vertical rod 33 and the cap portion 52 is arranged extending in the prospective direction of the shoji 3, the positioning of the holding member 50 with respect to the shoji 3 is accurately performed in two directions intersecting each other. Can be done.
(5) Since the insertion hole 432 is formed in the engagement piece 43, the screw 6 extends from the insertion hole 432 to the screw 6 even if the engagement piece 43 is located on the outer side in the direction of finding the vertical rod 33 than the attachment piece 41. , And the mounting piece 41 can be screwed to the vertical rod 33 to improve workability.
(6) Since the front edge portions 414 and 431 of the attachment piece portion 41 and the engagement piece portion 43 are arranged on the opening direction side of the shoji 3 with respect to the continuous portion 42, in the restored state of the leaf spring member 40, the continuous portion Both end portions of 42 are located apart from each other, and both the front end edge portions 414 and 431 side of the attachment piece portion 41 and the engagement piece portion 43 are wider than the continuous portion 42 side. For this reason, when the shoji 3 is going to move in the opening direction, the engaging piece portion 43 engages with the engaging portion 234, and a force that is expanded to the vertical frame 23 side is applied. It will be in the state caught between the scissors 33, and the opening of the shoji 3 can be suppressed more reliably.
(7) The engaging portion 234, which is a portion to which the airtight member 5 is attached, can be configured as a portion that engages with the opening restraining tool 4, and the configuration can be simplified.
