The present invention relates to an opening device.

Conventionally, there is a type of lock structure such as a vertical side window or a horizontal side window that is fixed by interlocking a pin with a handle in the center of the heel with a gremon specification. As another example, a type that attempts to prevent warping of the shoji due to heat by inserting a steel core into the upper and lower eaves incorporating the shoji and the left and right eaves to improve rigidity is known. It has been.
However, in the former type, it is necessary to provide an interlocking mechanism for each window size, which increases the cost. The latter type has a drawback that the core material is heavy and the manufacturing cost is high.

  However, the vertical window described in Patent Document 1 has a drawback in that the vertical and lower aluminum members in the lower part of the shoji expand and warp in a fire test or fire. At that time, even if the lock lock of the sub-lock is held in the locked state of the locking portion of the frame, the case of the sub-block is made of synthetic resin and melts and collapses due to heat. Cannot be held locked. Moreover, because of the fire, etc., the lower and vertical saddles made of the shoji aluminum member warp due to thermal expansion and operate to open against the frame, so that the metal lock rod not fixed by the sub-lock There was a fire-resistant defect that the frame was rotated with respect to the locking portion, the frame and the shoji were opened, and the inside and outside penetrated.

  The present invention has been made in view of such a problem, and in the event of a fire or the like, even when the lower part of the shoji is warped by heat and tries to open and act as an opening, the opening of the shoji can be suppressed. An object is to provide an apparatus.

The opening device according to the present invention is an opening device in which a shoji can be opened and closed in a frame formed by an upper and lower frame and left and right vertical frames, and the shoji incorporates an upper arm, a lower arm, and left and right vertical rods, A panel is held inside, and a sub-block is provided on the lower or vertical arm of the shoji, or both, and the sub-block is disposed so as to be capable of advancing and retreating on at least one of the lower arm and the vertical arm. It has a metal slide bar that can protrude to the outside of the shoji through the opening of the downspout, and an operation part that is exposed to the indoor side and moves the slide bar back and forth. A locking part that locks the slide bar is provided, and the lower bar or the vertical bar is a metal rotation prevention that regulates the rotation of the slide bar on the opposite side of the part that can protrude from the vertical bar opening in the longitudinal direction of the slide bar member is installed, Child, characterized in that is adapted to prevent a rotary preventing member rotation of the slide bar when warped into the outdoor side heat.
In the opening device according to the present invention, in the locked state where the slide bar of the sub-lock is locked to the locking portion of the frame body, the operation part of the sub-block or the connecting member between the slide bar and the operation part is melted due to a fire or the like When the lower part of the shoji is heated and bends due to heat from fire, etc., the slide bar is engaged with the opening of the lower part of the shoji. Although the slide bar rotates, since a rotation prevention member is installed on the lower or vertical hook, the rotation of the slide bar is prevented from coming into contact with the rotation prevention member to suppress the opening operation of the lower part of the shoji. Thereby, internal and external penetration can be prevented between the shoji and the frame.

Further, the rotation preventing member may be a fixing tool or a stopper provided in a lower arm or a vertical arm.
By using a screw or a stopper for fixing the panel holding bracket as the rotation preventing member, the rotation of the slide bar can be stopped reliably and the opening operation of the shoji can be prevented.

In addition, a restricting bracket having an opening into which the slide bar is inserted and retracted is fixed to the lower edge of the shoji or the side edge of the vertical fence, and the slide bar can be advanced and retracted in the opening. It is preferable that it is inserted.
Since the sliding bar is inserted into the opening of the shoji, the lower end of the door side of the shoji door is fixed to the lower end of the door or the side of the vertical eave, the lower part of the shoji is heated by the heat of the fire. When the slide bar is expanded and warped to open, the slide bar is pushed by the wall surface of the opening of the restricting bracket and rotates to contact the rotation prevention member. Therefore, the slide bar rotates between the opening and the rotation prevention member. Is prevented and the opening operation of the lower part of the shoji is suppressed. Thereby, internal and external penetration is suppressed between the shoji and the frame.

Further, the restricting bracket may be fixed to the lower rod or the vertical rod, and a rotation preventing member may be provided on the proximal end side of the slide bar.
With the sub-block slide bar locked to the locking part of the frame, when the shoji is opened, the slide bar abuts against the opening of the restricting bracket on the distal end and contacts the anti-rotation member on the proximal end. By being sandwiched in contact, the slide bar is sandwiched between the opening and the rotation preventing member to prevent rotation.

Further, the restricting bracket may be a single part that constitutes the vertical gutter.
By using a single part with an opening such as an aluminum member that constitutes the side edge of the vertical shaft as a regulating bracket, it is possible to suppress the opening operation due to warp of the shoji without attaching a regulating bracket separately, and increase the number of parts Can be suppressed.

  According to the opening device of the present invention, the slide bar is locked by the rotation preventing member even when the lower part of the shoji is thermally expanded and warped and opened during a disaster prevention test or fire, etc. It is possible to prevent the lower part from opening from the frame and to suppress the penetration inside and outside.

A locking portion 54 is formed to prevent the slide bar 40 from being opened and locked when the 40 is in the protruding position.

  The vertical window 1 according to the present embodiment has the above-described configuration, and the operation thereof will be described next. In the vertical window 1 according to this embodiment, the shoji 3 is closed on the frame 2 and the cam lock 35 of the main lock provided on the metal vertical wall 32 on the door end side is rotated, and the latch piece is moved to the vertical frame 7d. Is engaged with a latch receiving portion provided on the metal vertical frame 11. In addition, as shown in FIG. 8, the sub-block 37 is in a state where the operation portion 42 exposed to the indoor side of the metal lower arm 28 of the lower arm 19 is advanced to the vertical arm 21 side, and the slide bar 40 is moved to the vertical frame 7d. It is in the state locked to the latching | locking part 54 provided in the metal vertical frame 11.

When a fire test is performed in the locked state of the cam latch 35 and the sub-block 37, or when a fire or the like occurs, it is assumed that there is a flame on the indoor side. It is locked with the metal vertical frame 11 of the vertical frame 7d and is not easily thermally deformed. On the other hand, in the lower part of the shoji 3, since the members such as the case 38 and the connecting member 42a of the sub-block 37 are made of resin, they cannot melt and connect the metal slide bar 40 such as stainless steel.
And, when the metal downarms 30 and 32 of the vertical gutters 20 and 21 made of the aluminum member or the like of the shoji 3 and the metal lower gutter 28 of the lower gutter 19 are thermally expanded due to heat, the lower part of the shoji 3 is warped to the outdoor side, The slide bar 40 locked to the locking portion 54 of the metal vertical frame 11 is pushed by the opening 51a of the reinforcing plate 51 of the metal vertical rod 32 and rotates.

  When the slide bar 40 rotates with the locking portion 54 as a fulcrum in conjunction with the opening operation of the lower part of the shoji 3, the base end side portion of the slide bar 40 abuts on the regulating screw 49a provided on the metal lower rod 28 and rotates. The slide bar 40 is sandwiched between the regulation screw 49 a and the wall surface of the opening 51 a of the reinforcing plate 51 and stops. Therefore, the opening operation of the lower part of the shoji 3 is blocked, and the opening between the lower part of the shoji 3 and the frame 2 can be suppressed to prevent the inside and outside penetration.

  As described above, according to the vertical window 1 according to the present embodiment, in the fire test or fire, the lower metal rod 28 and the lower metal rods 30 and 32 below the shoji 3 are thermally deformed to cause warpage and the shoji. When the lower portion of 3 is opened and operated, even if the resin member of the sub-block 37 is melted, the slide bar 40 that is pushed and rotated by the opening 51a of the reinforcing plate 51 provided on the lower end side surface 32a of the metal vertical rod 32 is provided. Since the rotation can be prevented by abutting against the regulating screw 49a, the opening operation of the lower part of the shoji 3 can be prevented and the inner and outer penetrations with the frame body 2 can be prevented.

Note that the present invention is not limited to the vertical extension window 1 according to the above-described embodiment, and appropriate modifications and replacements can be made without departing from the gist of the present invention.
For example, in the above-described embodiment, the reinforcing plate 51 provided with the opening 51a on the distal end side in the longitudinal direction of the slide bar 40 is used for the metal vertical gutter 32 in order to restrict the rotation of the slide bar 40 of the sub-block 37 during the fire prevention test. Although the restricting screw 49a is provided at the base end portion and the reinforcing screw 51 is not provided, only the restricting screw 49a may be provided.

  Even in this configuration, when the lower part of the shoji 3 is bent and opened, the slide bar 40 is pushed and rotated by one part made of an aluminum member constituting the opening 32b of the lower end side surface 32a of the metal downpipe 32. The rotation of the slide bar 40 can be suppressed by the regulating screw 49a, and the lower part of the shoji 3 can be prevented from opening with respect to the frame 2. In this case, since the lower end side surface 32a of the metal vertical bar 32 is an aluminum member, it is easier to be thermally deformed than the reinforcing plate 51 made of steel or the like, but the slide bar 40 can be pushed. The reinforcing plate 51 and the lower end side surface 32a of the metal vertical rod 32 are included in the restriction fitting.

The reinforcing plate 51 may be provided at the front end portion of the metal lower rod 28 on the door end side instead of the lower end side surface 32 a of the metal vertical rod 32.
Further, although a fixing tool such as a restriction screw 49a is provided as a rotation prevention member for the slide bar 40 in the sub-block 37, any one of the surfaces of the substantially rectangular frame section of the metal lower collar 28 in place of the restriction screw 49a and others A protrusion protruding inward from the member may be provided as a stopper to restrict the rotation of the slide bar 40. This stopper is also included in the rotation preventing member.
Moreover, although the glass body 24 was hold | maintained with the glass holding metal fitting 48 on the inner surface of each collar of the shoji 3, instead of the glass body 24, a transparent panel, an opaque panel, etc. may be provided and these are named generically. It is called a panel.

  In the above-described embodiment, the case 38 and the slide bar 40 of the sub-block 37 are provided on both the metal lower rod 28 and the metal vertical rod 32, and the cradle 41 and the operation unit 42 are exposed to the indoor side. The case 38 and the slide bar 40 may be provided only in the metal downer 32. Alternatively, it may be provided only in the metal lower collar 28.

In the above-described embodiment, the window made of a composite sash of metal and resin has been described. However, the present invention is not limited to the composite sash, and the window made of a metal sash without a resin frame or resin cage. It goes without saying that can also be applied.
Further, the present invention is not limited to the vertical extending window 1 but can be applied to an opening device including not only various types of windows such as a horizontal extending window, an opening window, and an intermediate rotating window, but also a door.
