【Example】

This invention will be explained below based on the drawings.

0010 FIG. 1 shows an embodiment of the surface lattice according to this invention, and the surface lattice 1 shown in the figure is made up of two sheets. It is equipped with gratings 10 and 20. These grids 10 and 20 are located on the upper and lower sides of the opening It is designed to be installed between the lattice mounting bases 2 and 3 provided on each side. The locking device 4 installed on the indoor side (left side in the figure) of the contacting part maintains the straight state. It is now possible to

[0011] One of the two grids 10, 20 is attached to the upper and lower frames 11, 12 in a rod-like manner. Two locking portions 13 are provided (one each is shown in the figure), and these rod-shaped locking portions 1 3 and 13 are fixed to the grid mounting bases 2 and 3 in a locked state, respectively.

0012 The other lattice 20 has rod-shaped engaging portions 2 as moving engaging portions on its upper and lower frames 21 and 22. 3 are provided, and these rod-shaped engaging parts 23, 23 are connected to the grid mounting base 2, The guide grooves 5 and 6 as guide portions provided in the guide grooves 5 and 6 provided in the guide grooves 5 and 6 are engaged with each other.

It has a configuration in which it is connected to a grid moving part 5b via curved parts 5c, 5c. Also , the guide groove 6 is also a lattice drawer formed in the same direction as the lattice mounting base 3. The sections 6a, 6a are formed on the indoor side of the lattice mounting base 3 and along the longitudinal direction. It has a configuration in which it is connected to the child moving part 6b via curved parts 6c, 6c, When the two grids 10 and 20 are in a straight line, the rod-shaped engaging portion of the other grid 20 23, 23 are the respective grid drawing parts 5a, 5a and 6a of the guide grooves 5, 6, respectively. , 6a, and the locking device 4 is released. In this case, one of the gratings 20 is placed along the guide grooves 5 and 6 as shown by imaginary lines. The grids 10 can be moved to a position where they are overlapped on the indoor side. be.

[0014] Therefore, in this surface lattice 1, the two lattices 10 and 20 are locked by the locking device 4. Since the straight line is maintained, the security and fall prevention functions are not effective under normal conditions. The function of the shift will also be maintained.

[0015] Moreover, when the locking device 4 is released, the other lattice 20 is moved along the guide grooves 5 and 6. Being able to move to the indoor side of one grid 10 without being obstructed by surrounding buildings, etc. Therefore, an evacuation exit can be secured in case of an emergency.

[0016] FIG. 2 shows another embodiment of the surface lattice according to this invention, and the surface lattice 31 shown in the figure is two-dimensional. It is provided with two grids 40 and 50. These grids 40, 50 It is designed to be installed between the lattice mounting bases 32 and 33 provided on the lower side, respectively. A locking device 34 provided on the indoor side (upper left side in the figure) of adjacent parts allows straight lines. It is now possible to maintain the state.

[0017] One of the two grids 40, 50 faces inward to its upper and lower frames 41, 42. Two locking portions 43 are provided (only the upper inward locking portion 43 is shown in the figure), These inward locking parts 43, 43 are attached to the upper and lower edges of the body opening, respectively. It is fixed in a locked state.

[0018] The other grid 50 has parallel rollers 53 and 54 on its upper frame 51 as moving engagement parts. has been established. These parallel rollers 53, 54 are mounted on both ends of each support shaft 53a, 54a. - It is formed by supporting the wheels 53b, 53b and 54b, 54b, respectively. The first parallel roller 53 located on one side of the grating 40 of the upper frame 51 is located on the side of the other grating 40. At the tip of a rotating arm 55 pivotally connected to the upper end of the With the shaft 53a perpendicular to the longitudinal direction of the rotating arm 55, It is attached so that it can rotate in the horizontal direction as the rotating arm 55 rotates. be. Also, a second parallel roller 5 located on the opposite side of the upper frame 51 from one of the gratings 40 4 is attached to the tip of the inward bracket 57 fixed to the upper frame 51 of the other lattice 50. It is provided through a support pin 58 so as to protrude in the direction, and this support pin 58 is It is rotatable with respect to the orientation bracket 57.

At each outdoor side of the lattice extrusion parts 35a, 35a and the lattice mounting bases 32, 33, And the grating moving parts 35b, 35b formed parallel to one grating 40 are connected to the curved part 35. c and 35c, respectively. Moreover, the second parallel roller 54 ( The second guide rail 36 (36) that engages with the grid mounting bases 32, 33 The proximal end is located at the end of each indoor side opposite to one of the lattice 40, and the tip The end is located in the middle part of the grid mounting bases 32 and 33, and the whole has a substantially S-shape in plan. When the two grids 40 and 50 form a straight line, the other grid is The first parallel rollers 53 (53) of the child 50 are connected to the first guide rails 35, 35, respectively. It is located at each indoor end of each lattice extrusion part 35a, 35a. In addition, the second parallel rollers 54 (54) are connected to each of the second guide rails 36 (36). It is located at the proximal end, and when the locking device 34 is released, the guide rail is - one grating 40 along the lines 35, 36 as shown in phantom lines; They are designed so that they can be moved to a position where they overlap outdoors.

[0021] In other words, in this surface lattice 31, the two lattices 40 and 50 are locked by the locking device 34. Since the straight line is maintained, the security and fall prevention functions are not effective under normal conditions. The function of the shift will also be maintained.

[0022] Moreover, when the lock device 34 is released, the other grid 50 is moved to the guide rails 35, 3. 6 to the outdoor side of one grid 40 without being obstructed by surrounding buildings etc. This means that an evacuation exit can be secured in case of an emergency.

[0023] Further, in this surface grating 31, parallel rollers 53 and 54 are provided as moving engagement parts. Since it has a girder configuration, the other grating 50 can be moved smoothly.

[Effect of the idea]

As explained above, according to the planar lattice of this invention, two lattices can be placed in a straight line state. It has a locking device that secures one grid to the frame and the other grid. A moving engagement portion is provided on the other grid, and the moving engagement portion of the other grid is engaged with the moving engagement portion of the other grid. The structure has a guide section on the main body side that guides the child to a position overlapping one of the grids. Therefore, both the security function and fall prevention function must be maintained under normal conditions. It will also be possible to secure an evacuation exit in the event of an emergency such as a fire. A very good effect is brought about.
