【Example】

 The movable surface grating according to the present invention will be described below in detail with reference to the accompanying drawings and examples.

1 and 2, reference numeral 10 indicates a movable surface grating according to the present embodiment. The movable surface lattice 10 includes an upper frame 12, a lower frame 14, a pair of side frames 16a and 16b, and a surface lattice member 20 including a plurality of lattices 18. Further, the movable surface lattice 10 holds side frames 16a and 16b of the surface lattice member 20 and a pair of guide members 26a and 26b fixed to the window frame 22 via L-shaped brackets 24 and 24. A locking means 28 for locking the surface lattice member 20 on the guide members 26a, 26b to lock it, and an unlocking means 30 for unlocking the locked state of the surface lattice member 20 on the guide members 26a, 26b. (See FIGS. 3 and 4).

More specifically, the surface lattice member 20 includes a long upper frame 12 and a lower frame 14 which are arranged to face each other at an upper portion and a lower portion of a window frame 22 which surrounds the window 32, and the upper frame 12 and the upper frame 12. Also, a pair of side frames 16a and 16b that are fixed to the lower frame 14 at right angles to each other and a pair of side frames 16a and 16b, which are arranged substantially parallel to and separated from the side frames 16a and 16b by a predetermined distance. It is composed of a plurality of lattices 18 fixed in between. The window 32 is composed of a window glass 34 and a support 36 surrounding the window glass 34, and the upper and lower ends of the window frame 22 are slidably contacted with the support 36 to move the window 32. Freely holding grooves 38a, 38b are defined.

The upper frame 12 has a hollow portion 40 along the longitudinal direction, and is elongated in the horizontal axis direction. On the other hand, the lower frame 14 disposed so as to face the upper frame 12 is formed to have substantially the same shape as the upper frame 12, and the upper frame 12 and the lower frame 14 are provided at both ends thereof with the upper frame 12 and the upper frame 12, respectively. Also, a pair of side frames 16a and 16b that are orthogonal to the lower frame 14 and are formed in substantially the same shape are fixed (see FIGS. 3 and 4).

Outside the side frames 16a, 16b, guide members 26a, 26b each having a substantially U-shaped cross section are mounted along the longitudinal direction of the side frames 16a, 16b. The guide members 26a and 26b are fixed to the brackets 24 and 24, and the bent ends of the brackets 24 and 24 are fixed to the window frame 22 by screwing. In this case, the side frames 16a, 16b are slidably held in the recesses 42a, 42b defined in the guide members 26a, 26b, and the surface lattice member 20 including the side frames 16a, 16b is a guide member. It is formed so as to be linearly displaceable along 26a and 26b.

Locking means 28 for locking the side frames 16a, 16b to the guide members 26a, 26b is provided above the guide members 26a, 26b. The locking means 28 includes hole portions 44, 46 penetrating the side surfaces of the guide members 26a, 26b facing the window side and the side frames 16a, 16b, and a pin member 48 fitted in the hole portions 44, 46. . One end of a wire member, which will be described later, is connected to the window-side end of the pin member 48.

Between the upper frame 12 and the lower frame 14, a plurality of vertically-arranged grids 18 are arranged at a predetermined distance from each other. The lattice 18 is formed in the shape of a long prism with a hollow inside, and its upper and lower portions are fixed to the upper frame 12 and the lower frame 14, respectively.

As shown in FIGS. 1 to 4, an intermediate portion of the upper frame 12 facing the window side is for unlocking the locked state of the surface lattice member 20 locked by the pin member 48. An unlocking means 30 is provided. The unlocking means 30 includes a fixed plate 50 fixed to a side portion of the upper frame 12, a support plate 52 fixed to the fixed plate 50, and a shaft 54 that sandwiches the support plate 52. It has a short plate 56 and a long arm member 58 which are connected so as to rotate together. The cores 62 of the wire member 60 are connected to both ends of the plate 56, respectively. One core 62 of the wire member 60 is connected to the pin member 48 fitted in the holes 44 and 46. A support member 64 that supports the end portion of the wire member 60 in the vicinity of the pin member 48 is fixed to the upper frame 12 via a mounting member 66.

Therefore, by inserting the pin member 48 into the hole portion 46 defined in the side portions of the side frames 16a and 16b and the hole portion 44 defined in the guide members 26a and 26b, the side frame 16a is inserted. , 16b are locked by the guide members 26a, 26b to be locked. On the other hand, by rotating the arm member 58 in the direction of arrow A by a predetermined angle, the plate 56 linked to the arm member 58 so as to be interlockable via the shaft portion 54 is rotated in the direction of arrow B by substantially the same angle. To do. As a result, the core 62 of the wire member 60 connected to the plate 56 is pulled in the direction of arrow C, so that the pin member 48 is pulled in the direction of arrow D, and the pin member 48 is pulled from the holes 44 and 46. It can be released to be unlocked (see FIG. 4).

The movable surface grating 10 according to this embodiment is basically configured as described above, and its operation will be described next.

First, in a normal state, the movable surface grating 10 functions as a crime prevention to prevent a person entering through the window 32 (see FIG. 1). That is, by inserting the pin member 48 into the hole portions 44 and 46 defined in the side surfaces of the guide members 26a and 26b and the side frames 16a and 16b through the locking means 28, the window member 22 is fitted into the window frame 22. The side frames 16a and 16b are fixed to the fixed guide members 26a and 26b, and as a result, the entire surface lattice member 20 including the side frames 16a and 16b is fixed to the guide members 26a and 26b.

In this case, as shown in FIGS. 2 and 4, the arm member 58 constituting the unlocking means 30 has a side surface in the longitudinal direction of the arm member 58 substantially parallel to the support 36 of the window 32. They are in close proximity. Therefore, when the arm member 58 is rotated in the arrow A direction from the locked state formed by the pin member 48 to the unlocked state, the support body 36 interferes with the rotation of the arm member 58. I can't. As a result, since the surface lattice member 20 is fixed to the guide members 26a and 26b through the pin member 48 and the locked state is maintained, it becomes impossible to open the surface lattice member 20 from outside. By the surface lattice member 20, it is possible to prevent a person from illegally entering through the window 32.

Next, in the event of an emergency such as a fire, in order to make an emergency evacuation to the outside through the window 32, the locked state of the plane lattice member 20 by the pin member 48 is unlocked to open the plane lattice member 20. The case will be described.

When an evacuee opens the window 32 and tries to escape to the outside through the window 32 due to an emergency situation indoors, the evacuee opens the window 32 so that the window 32 is indicated by arrow E. Is displaced in the direction (see FIG. 4). Therefore, the evacuee is removed from the arm member 58 by removing the window 32 which is close to the side surface of the arm member 58 and becomes an obstacle when the arm member 58 is rotated in the direction of arrow A about the shaft 54 as a fulcrum. Can be displaced to the position of the chain double-dashed line in FIG. When the arm member 58 is rotationally displaced, the plate 56, which is also rotatably connected to the shaft portion 54 as a fulcrum, is rotationally displaced in the arrow B direction along with the arm member 58. When the plate 56 is displaced in the arrow B direction, the core 62 of the wire member 60 connected to both ends of the plate 56 is pulled in the arrow C direction. Therefore, the pair of pin members 48 connected to the end of the core 62 of the wire member 60 are both pulled in the direction of the arrow D, and the pin members 48 are formed in the holes of the guide members 26a, 26b and the side frames 16a, 16b. It comes off from the parts 44 and 46. When the pin member 48 is disengaged from the holes 44 and 46, the side frames 16a and 16b that have been locked to the pin member 48 release their locking action, and the surface including the side frames 16a and 16b is released. The lattice member 20 is in a displaceable state.

In this way, the surface grid member 20 falls substantially vertically downward (arrow direction) along the recesses 42a, 42b of the guide members 26a, 26b under the action of its gravity, as shown in FIG. It is in the open state and the opening can be defined. Therefore, it is possible for the evacuee to get over the window 32 and easily evacuate to the outside through the opening formed by opening the surface lattice member 20.

As described above, in the movable surface grating 10 according to the present embodiment, when a fire or the like occurs, the surface grating member 20 can be easily moved to define the opening portion so that the window 32 can be opened. You can safely evacuate outside. Also, in the conventional plane lattice, since the lattice forming the vertical axis is fixed between the upper frame and the lower frame forming the horizontal axis, for example, in the event of a fire, etc. When entering from the window 32 to rescue the vehicle, it was very difficult because the grid had to be cut and the window glass had to be destroyed to enter the room. However, in the movable surface grating 10 according to the present embodiment, it suffices to break the window glass 34 and remove the stopper of the window glass 34 to open the window 32, which is advantageous in that it can be rescued in a short time. is there.

In the present embodiment, the movable surface grating 10 is installed in the window frame 22 that surrounds the window 32, but the present invention is not limited to this. It is also possible to install it on the outer wall surface adjacent to it.

Furthermore, in this embodiment, the arm member 58 in the unlocking means 30 is described to be manually rotated by the evacuee. However, a solenoid valve is electrically connected to the fire alarm, It is possible to rotationally displace the arm member 58 by drivingly controlling the cylinder under the action of energizing or deenergizing the solenoid valve. With this configuration, the fire can be detected, and at the same time, the surface lattice member 20 can be dropped along the guide members 26a and 26b to define the opening, so that the outdoors can be swiftly and safely performed. You can evacuate.

[Effect of device]

 The movable surface grating according to the present invention has the following effects.

That is, in the event of a fire or the like, a large opening is defined by displacing the surface lattice member substantially vertically downward through the unlocking means, and it is possible to easily evacuate from indoors to outdoors through the window. can do.

Further, since the unlocking means cannot open the surface lattice member from outside, it can be used as a crime prevention surface lattice in a normal state.

Furthermore, in the event of an emergency such as a fire, when the person enters the room from the outdoors to perform rescue operations, the locked state can be simply unlocked through the unlocking means. It can intrude indoors and can save lives effectively.
