  As shown in FIGS. 3 and 4, the surface lattice 1 includes a pair of upper and lower hollow horizontal rails 2 and 3 that are fixed to a window sash S through a mounting bracket K at predetermined vertical positions in the window opening O. A manually opened / closed surface grid comprising a plurality of hollow vertical bars 4... Which are arranged in parallel in the longitudinal direction of the horizontal bars across the upper and lower horizontal bars 2 and 3. 2 and 3, a guide rail 5 and a rack 6 are provided over the entire length of the horizontal rail, and sliders 7 that are slidably held by the guide rail 5 are provided at the upper and lower ends of each vertical rail 4. In addition, the vertical beam 4a on one end side of the plurality of vertical beams 4... Has rotating shafts 9 provided with pinions 8 respectively engaged with the racks 6 and 6 of the upper and lower horizontal beams 2 and 3 at both upper and lower ends. Are connected to each other by a chain 10 as a rope body, and a vertical beam 4b on the other end side is connected. It is fixed to the lower both lateral beam 2.

  The structure of the surface grid 1 will be described in more detail. As shown in FIG. 3, the upper and lower horizontal rails 2 and 3 are integrally formed by combining a first mold material 11 and a second mold material 12 each made of an aluminum extrusion mold material. The guide rail 5 is formed on the side where the vertical rail 4 comes into sliding contact, and the groove 13 provided on the lower end side of the guide rail 5 has a shape steel material. A rack 6 made of is inserted and fixed. The guide rail 5 and the groove 13 are formed on the second mold member 12 side, and a slider insertion opening 14 is provided between the guide rail 5 and the first mold member 11 on the second mold member 12 side. Is formed over the entire length. As shown in FIG. 4, caps 15 made of synthetic resin are fitted to both ends of each of the horizontal rails 2 and 3, respectively.

  As shown in FIG. 4, each vertical rail 4 is made of an aluminum extruded hollow mold having a substantially trapezoidal cross section, and sliders 7 are attached to both upper and lower ends on the outer surface of the side wall 16 on the bottom side of the trapezoid. Accordingly, each vertical beam 4 can be slidably opened and closed along the guide rails 5 and 5 of the upper and lower horizontal beams 2 and 3 via the sliders 7 and 7 at both upper and lower ends. Further, synthetic resin caps 23 are fitted to the upper and lower ends of each vertical rail 4.

  Each slider 7 is formed by cutting an aluminum extruded mold having a cross-sectional shape as shown in an enlarged view in FIG. 3 (b) at a predetermined length, and is formed on the outer surface of the side wall 16 of each vertical rail 4. A board portion 7a attached with screws 18, a slider body 7b that projects horizontally from the upper side of the board portion 7a, a support wall portion 7c that projects downward from the tip of the slider body 7b, and the middle of the slider body 7b. The guide wall portion 7d protrudes downward from the portion, and the hollow wall portion 7e having an arcuate cross section formed at the tip of the slider body 7b. The support wall portion 7c is supported by the guide rail 5. A pair of rolling wheels 19 and 19 are pivotally supported.

  Thus, as shown in FIG. 3A, each slider 7 has the slider body 7b through the opening 14 of each horizontal rail 2 and 3 with its substrate portion 7a attached to the vertical rail 4. The board portion 7a, the slider body 7b, and the guide wall portion 7d are lightly engaged with the guide rails 5 of the horizontal rails 2 and 3, and are pivotally supported by the support wall portion 7c. The pair of wheels 19, 19 are supported on a pedestal portion 20 formed integrally with the inner lower end portion of the guide rail 5 and roll. The wheel 19 is supported on the pedestal portion 20 in a state where the slider 7 is slightly lifted with respect to the guide rail 5, and is for making the slider 7 slide lightly and smoothly.

  Further, on the upper surface of the slider main body 7b of each of the upper and lower sliders 7 attached to the vertical beam 4a on one end side, a fall prevention piece for preventing the vertical beam 4a from falling in the horizontal direction (direction perpendicular to the sliding direction). 22 is attached with screws 21. Further, as shown in FIG. 5, the vertical beam 4a on one end side, that is, the subsequent vertical beam 4 following the vertical beam 4a on the head side, A sound absorbing pad 27 is attached with screws 21 to mitigate a collision sound when the crosspieces 4 and 4 and the vertical crosspieces 4 and 4b collide with each other. The sound absorbing pad 27 is made of, for example, a rubber material.

  Further, since the outer surface of the substrate portion 7a of each slider 7 is in sliding contact with the opposing surfaces of the horizontal rails 2 and 3 when the vertical rail 4 slides, the contact friction resistance at the time of the sliding contact is made as small as possible. The opposing surfaces of the horizontal rails 2 and 3 with which the outer surface of the substrate portion 7a is in sliding contact (the outer surface portion of the guide rail 5 and the side surface portion of the horizontal rails 2 and 3 adjacent to the outer surface portion of the guide rail 5) As shown in FIG. 3 (a) and FIG. 5, a plurality of groove portions 24 extending in the longitudinal direction of the cross rails 2 and 3 are provided. In addition, you may provide such a groove part 24 in the board | substrate part 7a side of each slider 7 instead of providing in the horizontal rails 2 and 3 side.

  Inside the vertical beam 4a on one end side of the plurality of vertical beams 4 ..., a rotating shaft 25 is arranged along the longitudinal direction of the vertical beam 4a as shown in FIG. 3 (a) and FIG. Then, the pinions 8 and 8 which are pivoted by the bearings 26 and 26 and fixed to the upper and lower end portions of the rotary shaft 25 pass through the side wall 16 of the vertical rail 4a and the substrate portion 7a of the slider 7 (through the through holes). The holes (shown by 28) mesh with the racks 6 and 6 of the upper and lower horizontal rails 2 and 3, respectively. Therefore, when the vertical beam 4a on one end side is slid along the upper and lower horizontal beams 2 and 3 via the sliders 7 and 7 on both upper and lower ends, the rotary shaft 25 and the pinions 8 and 8 on both ends thereof are used. The speed on the upper end side and the speed on the lower end side of the vertical beam 4a are synchronized so that the vertical beam 4 can slide in any direction regardless of the position of the upper edge, the lower edge, or the middle part of the vertical beam 4 The vertical rail 4a can be easily slid along the horizontal rails 2 and 3 without falling back and forth.

  The chain 10 (cord) is inserted into the hollow circular wall 7e of the cross section of the slider 7 projecting from the vertical beam 4 into the upper and lower horizontal beams 2 and 3, and this chain 10 is tensioned. By caulking the hollow wall portion 7e of each slider 7 with the interval between the vertical beams 4, 4 being set constant, and fixing the hollow wall portion 7e and the chain 10 together, the adjacent vertical beams 4, 4 The four members can be connected to each other so as to be able to come into contact with each other within a predetermined interval.

  Since the chain 10 is housed in the horizontal rails 2 and 3, there is no fear of being cut off, the security function can be reliably maintained, and the appearance is good because it cannot be seen from the outside. In order to prevent rust, the chain 10 is preferably made of stainless steel. Further, a wire rope or the like may be used instead of the chain 10.

  The vertical beam 4b on the other end side is integrally fixed to the upper and lower horizontal beams 2 and 3 by screws or the like, although not shown. In addition, the surface grid 1 is a manual opening / closing type that opens and closes the window opening O by manually pushing and pulling the vertical beam 4a on one end side, that is, the leading vertical beam 4a. Appropriate locking means for fixing the leading vertical rail 4a to the horizontal rails 2 and 3 at the required opening and closing positions are provided at appropriate locations. This locking means prevents illegal intruders from unlocking from the outside in order to give the face grid 1 a security function, and removes the screen door in the event of an emergency such as a fire or for repairs. In some cases, it is necessary to be able to easily unlock and unlock from the indoor side.

  The use point of the surface grid 1 having the above configuration will be described. FIGS. 1A and 1B show a state in which the surface grid 1 is closed and the window opening O is closed. In the state, the vertical beam 4a at one end, that is, the leading vertical beam 4a is fixed to one end portion of the horizontal beam 2 by the locking means, thereby maintaining the crime prevention function.

  When the window opening O is opened in the event of an emergency such as the occurrence of a fire from the above closed state or when the insect screen door is removed, the locking means is unlocked, and then the leading end shown at the right end of FIG. When the vertical beam 4a is gripped and slid to the left in the figure, the subsequent vertical beam 4 ... is sequentially pushed into the ball-throwing state from the vertical beam 4a and fixed at the left end as shown in FIG. The window opening O is opened by sliding toward the vertical beam 4b. Therefore, it is possible to escape from the opened window opening O to the outside or take out the screen door. Further, when the top vertical rail 4a is gripped from the state in which the window opening O is opened in this way and is slid to the right in the figure, the subsequent vertical rails 4 ... are pulled by the chain 10, Closed state. In this closed state, the leading vertical rail 4a may be fixed to the horizontal rails 2 and 3 by the locking means.

  When the top vertical rail 4a is gripped and slid open and closed as described above, the speeds of the upper end side and the lower end side of the vertical rail 4a are synchronized by the rotary shaft 25 and the pinions 8 and 8 at both ends thereof. Therefore, no matter which position of the upper end, the lower end or the middle part of the vertical beam 4 is gripped, the vertical beam 4a is not tilted back and forth in the sliding direction. The vertical beam 4a can be easily slid along the horizontal beam 2 and 3.

  Further, on the sliders 7 provided on all the vertical bars 4... Including the vertical bars 4 a and 4 b on both ends, wheels 19 that roll while being supported by the guide rails 5 of the respective horizontal bars 2 and 3 are pivoted. Since the wheel 19 is supported, and the slider 7 is supported on the pedestal portion 20 with the slider 7 slightly lifted from the guide rail 5, the sliding motion of the slider 7 becomes very light. Therefore, the sliding opening / closing operation of the window opening O by the vertical bars 4... Can be performed quickly and easily and smoothly.

  In addition, since each slider 7 is provided with a fall prevention piece 22 on the upper side of the slider body 7b, it is possible to prevent the vertical fall of the vertical rail 4 from falling in the horizontal direction while the vertical rail 4 is slid. Can be performed even more lightly.

  6 (a) and 6 (b) are front views of a state in which a surface lattice 31 which is another embodiment of the fence device according to the present invention is installed in the window opening portion O, as viewed from the outdoor side, (b) FIG. 7 is a front view of the coplanar lattice 31 as seen from the outdoor side, and FIG. 7 is an enlarged sectional view taken along the line ZZ in FIG. FIG. 8 is an enlarged vertical sectional view of the vertical beam 4 a on one end side of the same-surface lattice 31, and FIG. 9 is an enlarged vertical sectional view of one end side portion of the horizontal beams 2 and 3 of the same-surface lattice 31. The surface lattice 31 is an electric opening / closing surface lattice in which an electric motor 30 for driving the rotary shaft 25 to rotate forward and backward is provided in the vertical beam 4a on one end side, and the vertical beam 4a is automatically slid. .

  The surface lattice 31 of the embodiment shown here is the previous embodiment described with reference to FIGS. 1 to 5 except that an electric motor 30 for driving the rotary shaft 25 supported in the vertical beam 4a on one end side is provided. Since the configuration is almost the same as that of the surface lattice 1, the same components as those of the surface lattice 1 are denoted by the same reference numerals in FIGS. In the case of this surface lattice 31, the motor 30 that rotationally drives the rotary shaft 25 also serves as a locking means for fixing the leading vertical beam 4a to the horizontal beams 2 and 3 at the required opening / closing position. There is no need to provide locking means such as the surface lattice 1 of the embodiment.

  The usage procedure of the surface lattice 31 will be briefly described. FIGS. 6A and 6B show a state in which the surface lattice 1 is closed and the window opening O is closed. The vertical beam 4a, that is, the top vertical beam 4a is fixed to the end portion of the horizontal beam 2, thereby maintaining the crime prevention function. In the case of an emergency such as the occurrence of a fire from this closed state or when the insect screen door is removed, the window opening O is not shown, but, for example, the “open button” of the push button switch for opening and closing the face grid is pressed. Then, while the electric motor 30 rotates in a predetermined direction to drive the rotary shaft 25 and the pinions 8 and 8 and keep pressing this "open button", the leading vertical rail 4a is as shown in FIG. By sliding automatically to the left, the vertical bars 4... Following the vertical bars 4 a are sequentially pushed into the ball-thrust state, and the window opening O is opened. When the hand is released from the “open button”, the electric motor 30 stops and the vertical rail 4a stops at the required open position and is fixed at that position.

  In addition, when the “close button” is pressed from the state in which the window opening O is opened as described above, the electric motor 30 rotates in the opposite direction to that at the time of opening, and the rotating shaft 25 and the pinions 8 and 8 are reversed. While driving and pressing this “close button”, the top vertical beam 4a slides to the right in FIG. 6 (a), and the subsequent vertical beam 4... Is pulled by the chain 10 and closed. It becomes a state. When the "close button" is released, the electric motor 30 stops and the vertical rail 4a is fixed at the required closed position. The opening and closing of the surface lattice 31 can be remotely operated by a remote controller equipped with the above-described surface lattice opening / closing operation push button switch.

  FIG. 10 is a front view of a state in which the surface lattice 41 according to another embodiment is installed in the window opening O as viewed from the outdoor side. FIG. 11A is a vertical beam on one end side of the surface lattice 41. 4a is an enlarged longitudinal sectional view of FIG. 4a, (b) is a sectional view taken along line VV of (a), and (d) is a sectional view taken along line WW of (a). This surface lattice 41 is a manually openable / closable surface lattice similar to the surface lattice 1 of the previous embodiment, but adopts one in which pin-shaped teeth 8a are formed as the pinion 8 provided on the vertical beam 4a on one end side. In addition, as the rack 6 provided on each of the upper and lower horizontal rails 2, 3, a tooth hole 6 a where the pin-shaped teeth 8 a of the pinion 8 of the vertical rail 4 a on one end side mesh with the second mold member 12 of each horizontal rail 2, 3 What is formed at a constant pitch in the longitudinal direction of the crosspiece is adopted.

  Since the surface lattice 41 has almost the same configuration as the above-described surface lattice 1, the same components as those of the surface lattice 1 are denoted by the same reference numerals in FIGS. 10 and 11, and the description thereof is omitted. Since the method of use is the same as that of the surface lattice 41, the description thereof is omitted. In this surface lattice 41, since the tooth holes 6a with which the pin-shaped teeth 8a are engaged can be directly formed in each of the cross rails 2 and 3 as the rack 6 in particular, the rack 6 of the normal shape used for the surface lattices 1 and 31 can be formed. Thus, the mold material for forming the rack becomes unnecessary, and the weight of the horizontal rails 2 and 3 can be reduced by the amount of the mold material. The surface lattice 41 is a manually openable / closable surface lattice, but may be electrically opened and closed like the surface lattice 31.
