Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an area lattice that can be accessed in an emergency.

[0002]

[Prior art]

 Like the sliding door, the surface lattice attached to the outside of the opening / closing window is provided in the frame so that two main surface lattices can be opened and closed in a sliding door type. And there are those that can be opened and closed in any direction, and those that can be opened and closed in only one direction. In addition, there is a system in which a locking mechanism is attached to these area lattices.

[0003]

[Problems to be solved by the device]

 As mentioned above, since the area lattice is normally two sliding doors, one side cannot be opened even if it is opened on either side. Moreover, since the length of the frame body requires a length of two sheets, it requires a large area, which increases the cost for mounting and the material cost.

In an emergency, even if a large piece of furniture is to be carried out from the surface lattice, the size of the opening is one and the width is so narrow that it is difficult to carry the furniture.

[0005]

[Means for Solving the Problems]

 Racks are attached to each of the upper and lower frames along the length direction thereof, and a predetermined number of rod-shaped base materials are arranged between the racks at predetermined intervals along the length direction of the racks. The rod-shaped base material is vertically connected to the adjacent rod-shaped base material via a wire, and at least the bar-shaped base material on the opening end side has a gear that rotates vertically in mesh with the rack. A surface lattice, which is mounted in a synchronized state, and further has a guide mechanism that moves along the guide mechanism of the frame body on each rod-shaped base material described above.

[0006]

The surface lattice of the present invention has a structure in which a predetermined number of rod-shaped bases arranged in the length direction are connected to each other with wires at predetermined intervals in the frame, and therefore the open end portion The rod-shaped substrate is opened by moving it to the adjacent rod-shaped substrate side, and sequentially moving to the other end side. In that case, the rod-shaped substrates come into contact with each other, and the size of the opening becomes the width obtained by subtracting the width of the rod-shaped substrate from the total opening width, that is, the size of the width space between the rod-shaped substrates, and the opening area increases. . In addition, since the rod-shaped base material can be opened and closed sequentially through a wire, it is lighter in weight than conventional framed products and can be operated smoothly.

【Example】

 In FIG. 1, 1 is a surface lattice, 2 is a rectangular frame, and 3 is a bar-shaped substrate, which is composed of a predetermined number, and is connected to each other by wires 4 at a predetermined interval above and below. Racks are attached to the upper and lower frames 2a and 2b along the length direction thereof. Gears that rotate up and down on the rack are attached to the rod-shaped substrate. The gear is provided on at least the rod-shaped substrate located on the open end side, and the other rod-shaped substrates may or may not be provided on all or a part thereof.

A guide mechanism is provided on the upper and lower frames. Therefore, the rod-shaped substrate moves smoothly. This guide mechanism may be provided on one side of the upper and lower sides. It is also possible to provide a locking mechanism on the bar-shaped base material on the opening end side and configure the lock with the locking mechanism of the corresponding vertical frame.

FIG. 2 shows an open state of the area lattice. The width of the arrow is the opening width. All the rod-shaped base materials 3 have been moved to the other end side, and are in a fully opened state. The rod-shaped substrate is sequentially moved manually from the opening end side and concentrated on the other end side. When closing, if the opposite operation is performed, it will be pulled back in sequence by the wire and will be in the closed state. The opening side of the rod-shaped base material may be set to either one side or both sides. As is clear from the above illustration, since rod-shaped base materials having a width of 20 to 40 mm are connected by wires at intervals of 100 to 150 mm, a wide space can be formed in the opened state.

In FIG. 3, racks 5 are attached to the upper and lower frames 2a and 2b along the length direction thereof. Bar-shaped base materials 3 are arranged between the racks at predetermined intervals along the length direction of the racks. This interval should be determined from the perspective of crime prevention. Reference numeral 4 connects the rod-shaped base materials to each other with a single wire. The wire fixes the ball with a space between the rod-shaped substrates.

Reference numeral 3a is a square pipe made of a hollow square aluminum material, and cap members 3b are fixed to the upper and lower ends thereof. The cap member has a protruding portion provided on one side of the square pipe to serve as a wire connecting portion, and the ear is clamped and fixed between the cap member and the pressing member 3c.

Reference numeral 6 denotes a gear attached to the upper and lower ends of the rod-shaped base material. This gear is integrally connected by an interlocking shaft 6a so as to rotate synchronously. Therefore, the gear 6 rotates and moves along the rack 5. This gear may be provided on all the rod-shaped substrates, or attached to at least the rod-shaped substrate on the open end side. The rod-shaped base material with gears moves stably along the rack.

Reference numeral 7 denotes a guide mechanism integrally molded with the upper frame and the lower frame. The guide mechanism of the upper frame is located between the square pipe and the cap material, and guides the movement of the rod-shaped base material. Further, the guide mechanism 7 of the lower frame is a rail and guides the wheel 3d attached to the cap member. 7a constitutes a wire receiving portion together with the guide mechanism 7. Even when the rod-shaped substrate is open, the wire is not disturbed and is not exposed to the outside, and the wire does not get tangled.

FIG. 4 shows a meshing state of the rack 5 and the gear 6. These may be aluminum materials or plastics materials. FIG. 5 shows an exploded view of the cap member 3b. A wire is connected to the cap member via a pressing member 3c at a position opposite to a mounting portion 3g fitted into the hollow end of the square pipe. 3e and 3f are wire passage grooves. A ball receiving groove is formed in this central portion.

FIG. 6 is a schematic plan view of the wire. A ball 4a is fixed to the wire 4 at a predetermined distance where the rod-shaped base material is connected, and the ball 4a is tightened between the main body of the cap material and the pressing member, so that the wire and the rod-shaped base material are connected to each other. It is firmly connected and fixed.

FIG. 7 shows another embodiment of the present invention. The rack 5a is integrally molded with the frame. Further, the cap member 3b of the upper frame has a structure in which both sides of the cap member 3b project further to the vicinity of the side of the frame body, and a guide mechanism is provided during movement. The cap material of the lower frame is also close to the side of the lower frame. A concave groove guide 3h is formed in the cap member 3b, and a guide protrusion 2c provided on the lower frame is fitted therein. Therefore, the guide mechanisms are mutually configured. The present invention is not limited to the above embodiment. Various things are included without departing from the technical idea of the present invention.

【effect】

 Since the surface lattice of the present invention has a structure in which a predetermined number of rod-shaped base materials arranged in the length direction are connected to each other with wires at predetermined intervals in the frame, the rod-shaped base material at the end on the open side is provided. Is moved to the adjacent rod-shaped base material side, and sequentially moved to the other end side to open. In that case, the rod-shaped substrates come into contact with each other, and the size of the opening becomes the width obtained by subtracting the width of the rod-shaped substrate from the total opening width, that is, the size of the width space between the rod-shaped substrates, and the opening area increases. . In addition, since the rod-shaped base material can be opened and closed sequentially through a wire, it is lighter in weight than conventional framed products and can be operated smoothly.
