It can be automatically opened and closed. In addition, when the fire alarm detects heat or smoke due to an emergency such as a fire in the room, the detection signal causes the face grid 2 to be opened from the closed position to the open position. Even if there is a child or the like, the child or the like can escape without opening the surface lattice 2 by himself or herself, and rescue work from the outside can be easily performed.

  A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 (a) is a front view of the state in which the surface lattice is in the closed position, and (b) is (a). ) Is an enlarged cross-sectional view taken along the line X-X of (), showing a state in which the louvers of the surface lattice are open (in a horizontal posture). 2 is an enlarged sectional view taken along line YY in FIG. 1B, FIG. 3A is an enlarged sectional view taken along line VV in FIG. 1A, and FIG. (A) It is a WW line expanded sectional view of (a), and all are sectional drawings which show only a surface lattice. In these drawings, reference numeral 1 denotes a window opening of a building, and a surface lattice 2 is disposed outside the window opening 1. Reference numeral 3 denotes a metal fixed frame fixed to the indoor side in the window opening 1, and the fixed frame 3 itself may be a sash frame in which, for example, a sliding shoji is fitted, or the fixed frame 3. In some cases, a sash frame is attached.

  The surface lattice 2 has a surface lattice peripheral frame 7 composed of left and right vertical frames 4 and 4 and upper and lower horizontal frames 5 and 6, and a plurality of horizontally long louvers 8 extending horizontally in the surface lattice peripheral frame 7. It is arranged in a shape. As shown in FIG. 1 (b) and FIG. 2, the fixed frame 3 is composed of left and right vertical members 3a, 3a, an upper horizontal member 3b and a lower horizontal member (not shown). Brackets 9 and 9 for attaching the surface lattice are attached to the upper end portion in 3a, and the upper end portions of the left and right vertical frames 4 and 4 of the surface lattice peripheral frame 7 are pivotally supported at the end portions of both brackets 9 and 9, respectively. The surface lattice 2 is pivotally attached by the shafts 10 and 10, so that the surface lattice 2 can be pivoted and opened to the outdoor side around both pivotal support shafts 10 and 10 located on the upper side of the surface lattice peripheral frame 7.

  Between the surface grid 2 and the fixed frame 3 provided on the indoor side of the window opening 1, the surface grid 2 is closed to the open position where the window opening 1 is opened and the window opening 1 is closed. A face grid opening / closing means 11 is provided to automatically open and close the closed position. The surface grid opening / closing means 11 is disposed along the left and right vertical members 3 a of the fixed frame 3, and is a link mechanism 12 interposed between the vertical members 3 a of the fixed frame 3 and the surface lattice 2. And a linear actuator 13 as a linear motion reciprocating drive means for reciprocatingly driving the link mechanism 12 to a folding position corresponding to the closed position of the surface grid 2 and a deployed position corresponding to the open position of the surface grid 2. Is done. The linear actuator 13 is, for example, an electric linear actuator.

  The link mechanism 12 of the surface grid opening / closing means 11 includes a link 12a pivotally attached to a mounting member 14 having one end portion mounted in each vertical member 3a of the fixed frame 3 by a pin 15, and one end portion being a vertical portion of the surface grid 2. It consists of a link 12b pivotally attached to a mounting member 16 attached to the frame 4 by a pin 17, and the other ends of both links 12a and 12b are pivotally attached by a pin 18. The linear actuator 13 reciprocates so that the movable body 13b expands and contracts in the axial direction with respect to the cylindrical main body 13a. The base end portion of the cylindrical main body 13a is attached in the vertical member 3a of the fixed frame 3. The mounting member 19 is pivotally attached by a pin 20, and the distal end portion of the movable body 13 b is pivotally attached by the pin 18 together with the other end portions of both links 12 a and 12 b of the link mechanism 12.

  The operation of the surface lattice opening / closing means 11 will be described. As shown by the solid line in FIG. 2, when the surface lattice 2 is in the closed position, the link mechanism 12 and the linear actuator 13 are placed in the vertical member 3 a of the fixed frame 3. Folded to fit in Thus, when the movable body 13b of the linear actuator 13 is extended from this state, the link mechanism 12 expands from the folding position to the open position to open the surface lattice 2 as shown by the phantom line in FIG. When the movable body 13b of the linear actuator 13 is contracted, the link mechanism 12 is folded from the open position and is housed in the vertical member 3a together with the linear actuator 13, and the surface lattice 2 is closed.

  Further, the surface grid opening / closing means 11 normally holds the surface grid 2 in the closed position, and the surface grid 2 is closed by a detection signal when the fire alarm detects heat or smoke when an emergency such as a fire occurs. It is made to drive open to an open position. FIG. 5 shows a flow chart of the electric system of the surface grid opening / closing means 11, wherein 21 is a control unit for electrically controlling the linear actuator 13 as a direct acting reciprocating drive means, and 22 is an on / off switch for the linear actuator 13. A manual operation unit 23 such as a push button to be operated is a fire alarm.

  Therefore, since the surface lattice 2 is normally held in the closed position, for example, when the surface lattice 2 is opened when the glass of the sliding door shoji provided in the fixed frame 3 is cleaned from the outside, a push button is used. By operating (switching on) the manual operation unit 22 such as the above, the movable body 13b of the linear actuator 13 is extended, and the surface lattice 2 can be automatically opened. By operating the switch off, the face grid 2 is automatically closed. Further, when an emergency such as a fire occurs in the room and the fire alarm detects heat or smoke, the detection signal is sent to the control unit 21 and the linear actuator 13 of the surface lattice opening / closing means 11 extends. Operates and automatically opens the face grid 2 via the link mechanism 12, so that even if there are children or persons with disabilities in the room, the child etc. can escape without opening the face grid 2 by themselves. And rescue work from outside can be done easily.

  Next, the structure of the louver 8 of the surface lattice 2 will be described in more detail. The surface lattice 2 extends in a horizontal direction within a surface lattice peripheral frame 7 composed of left and right vertical frames 4 and 4 and upper and lower horizontal frames 5 and 6. This is a movable louvered surface grid in which a large number of louvers 8 are arranged in a multistage manner so as to be able to be interlockedly opened and closed.

  As shown in FIGS. 2 and 4, each louver 8 is formed of an aluminum alloy extrusion mold formed in a hollow shape having a substantially S-shaped cross section and a substantially elliptical cross section at the center. The oval hollow portion 25 is divided into substantially triangular hollow portions 25 a and 25 a on both sides via a partition wall portion 26, and screw pockets 27 are formed in the partition wall portion 26 over the entire length of the louver 8.

  Further, as shown in FIG. 4, end caps 28 integrally formed of synthetic resin are attached to both ends of each louver 8, and each end cap 28 is a cap that covers the hollow portion 25 on the end surface of the louver 8. On the inner end side of the main body 29, a pair of fitting convex portions 30, 30 to be fitted to the both side triangular hollow portions 25 a, 25 a of the hollow portion 25 are projected, and on the outer end side of the cap main body 29, A support shaft portion 31 rotatably supported by a shaft hole 34 provided in the inner plate 4o of the vertical frame 4 of the lattice peripheral frame 7, and a diameter smaller than that of the support shaft portion 31 on the outer end side of the support shaft portion 31. The square shaft portion 32 is formed coaxially, and further provided with a screw insertion hole 33 penetrating the support shaft portion 31, the square shaft portion 32, and the shaft core of the cap body 29.

  Thus, in order to attach the louver 8 to the left and right vertical frames 4, 4 of the surface lattice peripheral frame 7, end caps 28, 28 are attached to both ends of the louver 8, and then the support shaft portions of the end caps 28, 28 are attached. The louvers 8 are rotatably pivoted on the left and right vertical frames 4 and 4 by inserting the 31 and 31 into the shaft holes 34 and 34 in the inner plates 4o and 4o of the vertical frames 4 and 4, respectively. Thereafter, a square hole 36 provided on one end side of the crank arm 35 is fitted into the square shaft portion 32 of the end cap 28 on one end side of each louver 8, and a screw is inserted into the opposite end portion of the square hole 36. The screw 38 inserted through the hole 37 is screwed into the screw pocket 27 of the louver 8 through the screw insertion hole 33 of the end cap 28 to fix the end cap 28 to the louver 8, and the crank arm 35 is fixed to the end cap 28. To fix.

  After the crank arm 35 is attached and fixed to the end cap 28 on one end side of each louver 8 as described above, the diameter-reducing split pin 39 projecting from the tip side of each crank arm 35 is connected to the linkage 40. By fitting into the pin holes 40a, the louvers 8 are interlocked and connected via the crank arm 35, and this state is shown in FIG.

  Further, on the other end side of each louver 8, as shown in FIG. 3 (b), for example, a rotating disk 41 is concentrically attached and fixed to the square shaft portions 32 of two upper and lower required end caps 28, These two rotating disks 41 and 41 are interlocked and connected by connecting rods 42 and 42, and the lower end portion of one connecting rod 42 is connected to the movable body 43 b of the linear actuator 43 provided at the lower end portion in the vertical frame 4. .

  Similar to the linear actuator 13 of the surface lattice opening / closing means 11, the linear actuator 43 reciprocates so that the movable body 43b expands and contracts in the axial direction with respect to the cylindrical main body 43a. Is pivotally attached to the vertical frame 4 side, and the distal end portion of the movable body 43b is pivotally attached to the lower end portion of the linkage 42. In FIG. 3B, when the movable body 43b of the linear actuator 43 is extended, each louver 8 is in the closed position. From this state, if the movable body 43b is contracted, the linkage 42 is moved. When the rotary disk 41 is rotated by 90 °, each louver 8 is held in the open position as shown by the phantom line in FIG. 3, and when the movable body 13b is extended, the rotary disk 41 is connected via the linkage 42. 41 rotates 90 ° in the opposite direction, and each louver 8 is held in the closed position shown by the solid line in FIG.

  According to the movable louver surface lattice 2 as described above, the louvers 8 can be automatically opened and closed simultaneously by operating the linear actuator 43.

  In the above-described embodiment, the electric linear actuator 13 is used as the direct-acting reciprocating drive means of the surface lattice opening / closing means 11, but the linear actuator is not limited to the electric type, but an electromagnetic type or the like. May be used. The direct acting reciprocating drive means is not limited to various linear actuators, and an air cylinder or a hydraulic cylinder may be used. The same applies to the linear actuator 43 used to automatically open and close the louver 8. However, the linear actuators 13 and 43 such as the electric type can be reduced in size and weight, and the piping of the pressure fluid as in the case of the cylinder is not required and the control is simple. It can be easily installed even in a narrow space in the frame 7, and the manufacturing cost is reduced.

  Further, in the above-described embodiment, the surface lattice 2 is configured to be able to rotate and open in the vertical direction toward the outdoor side around the support shaft 10 positioned on the upper side of the surface lattice peripheral frame 7, but this is an example. Thus, the surface lattice according to the present invention may be configured such that it can be pivoted and opened in the left-right direction around a support shaft located on the left and right sides (left and right vertical frames 4). A structure that can be pivoted and opened in the vertical direction around a support shaft located on the lower side of the plate may be used.

  Further, in the above-described embodiment, the surface lattice 2 is provided on the outdoor side of the window opening 1 of the building, and the fixed frame 3 is provided on the indoor side of the surface lattice 2. A fixed frame 3 as a sash frame for a shoji screen may be attached, and a surface lattice 2 may be provided on the indoor side of the fixed frame 3. In this case, the fixed frame 3 is not limited to the window opening 1, but the window opening. The surface lattice 2 may be provided on the indoor side of the fixed frame 3 and further on the indoor side. Further, the surface lattice 2 may be provided so as to protrude from the window opening 1 to the outdoor side.
