2. Description of the Related Art In general, a screen lattice is often provided outside a window of a building such as a house for the purpose of crime prevention or decoration. The surface grid is firmly fixed to the outside of the window so that it cannot be easily opened from the outside. However, these days, in a high security grid,
On the contrary, it has been pointed out that in the event of a fire, there is a danger that people will be trapped in the room, and from the viewpoint of disaster prevention, a strong and open grid is required. I have. This is a so-called escape surface lattice. In this escape surface lattice, when newly constructed, a surface lattice and a window frame for mounting the surface lattice are integrated to form a formwork, and the integrated formwork is often attached to a wall opening. In general, the type of escape surface grid is a sliding grid, or a grid with one rail and one of two grids that can be fitted and the other can be opened. There was a bellows type that was pulled in one direction.

[0003]

However, there are many types of windows in the windows due to the type of the building or the difference in the construction person, etc. There are many kinds. Therefore, as described above, when attempting to attach an integrally molded product of the escape surface lattice and the window frame at the time of new construction, it is necessary to select various types of surface lattices and window frames according to the shape of the window. However, as a result, there has been a problem that many types of mold members constituting such an integrally molded product must be prepared. That is, when a window frame and a surface lattice conforming to the window frame are determined in accordance with the type or use of the window and the customer's request, an escape surface lattice integrated molded product is manufactured using a form material corresponding to the shape. Must be used, a very large number of types of form materials to be used, productivity,
There was a problem that cost was not enough. Furthermore, in the case of attaching the escape surface grid of the integral molding type,
There was also a problem with the mounting strength. In addition, when newly installing an escape surface grid on an existing building, it is necessary to tear down the periphery of the window frame and install an integrated escape surface grid in which the window frame and escape surface grid are integrated, which is a large task. There was also a problem that it would be difficult. In view of the above situation, the present inventor has proposed that the existing sash frame does not require a demolition work around the window frame, and that the escape sash frame can be of any form, such as a sliding type, a drop-down type, or a pull-up type. Can be appropriately selected in combination with an arbitrary window frame, and can be easily and firmly attached in a variety of ways. When attaching an escape surface grid to a new building, a plurality of formwork members are required. A window frame of an arbitrary shape can be attached to a predetermined window as appropriate without any need, and a retrofitting escapement grid that can easily and securely attach a surface grid of an arbitrary form to the window frame later, and is usually provided as an external security device. We have continued our research on creating an escape operation mechanism that can be easily opened from the inside in the event of a fire or other disaster by installing it so that it cannot be opened from the ground. .

A frame, a pair of upper and lower horizontal frames, and a surface lattice body, and a fitting portion having a U-shaped cross section to be fitted to the extending portion is formed in the longitudinal frame in the longitudinal direction. The horizontal frame body is provided with at least one row of rails, and the horizontal frame body is fitted into the vertical frame body and fixed in a four-sided frame shape. And a surface grid attached to an extending portion extending in the direction parallel to the window surface on the outermost side of the sash in the building, the surface grid being a pair of left and right vertical frames and a pair of upper and lower horizontal frames. And a vertical lattice body, and the vertical frame body A U-shaped fitting portion is formed in the longitudinal direction and a fitting portion for the horizontal frame is formed, and the horizontal frame is provided with at least one row of rails on which the surface lattice body can slide. A rear surface lattice in which the body is fitted into the insertion portion of the vertical frame body and fixed in a four-sided frame shape; a locking bar and the locking bar; And an operating bar pivotally connected to the engaging plate. The operating bar is disposed in an operating rod having a length longer than that of a human arm. The present invention solves all of the above-mentioned problems by providing a retrofitting escapement grid in which an escapement operation mechanism having a bar and / or an operation bar having a length longer than a human arm is provided.

[0007]

[Function] A surface lattice can be easily attached by retrofitting by using an extension portion (sometimes called a sash feather) extending in the direction parallel to the window surface on the outermost side of the existing sash for the Ami door. . When installing the escape surface grid at the time of new construction,
A window frame of an arbitrary shape is attached to a predetermined window, and an escape surface lattice of an arbitrary shape can be easily and firmly attached to this window frame by retrofitting. Therefore, there is no need for a form member for obtaining an integrally molded product. Also, when attaching the escape surface grid to an existing building, use the extension that extends in the direction parallel to the window surface on the outermost side of the existing sash without the need for demolition work around the window frame. Thus, the escape surface lattice having an arbitrary shape can be arbitrarily selected from many variations and can be easily attached detachably. Since the locking bar is provided using the play space of the sash, the workability is good without making a hole in the wall. Moreover, the holes are not drilled in the wall, so the rain is good. Bar insertion locking holes are provided in the vertical frame near the left and right sides of the plane grid body disposed in the vertical frame and the horizontal frame, and locking bars are inserted into the bar insertion locking holes respectively. Have been. Therefore, by the insertion and locking of the locking bar, the surface lattice main body is fixed so that it cannot be moved from outside. In addition, the operating rod, the operating bar, and / or the locking bar are longer than a human arm. In order to release the surface grid, the operating rod is decentered in the horizontal direction with respect to the locking bar, and the tip of the operating bar is projected from the operating rod, and this operating bar is located on the same axis as the locking bar. In this case, it is necessary to release the insertion lock of the locking bar into the bar insertion locking hole by pulling the operation bar.
First, if the locking bar is longer than a human arm, the operating rod cannot be reached even if an intruder from outside extends his arm from the gap of the surface lattice. Therefore, the operation of displacing the operating rod in the horizontal direction with respect to the locking bar to release the insertion locking of the locking bar into the bar insertion locking hole cannot be performed, and the surface grid cannot be opened. . Also, when the operating rod and the operating bar are longer than a human arm,
Even if an intruder from the outside extends his arm from the gap of the surface grid and eccentrically positions the operating rod horizontally, it does not reach the tip of the operating bar protruding from the operating rod, and therefore operates the operating bar. Cannot open the surface grid. Further, even when both the operation bar and the locking bar are longer than a human arm, an intruder from the outside cannot reach the tip of the operation bar and cannot open the surface lattice. Therefore, even if the user attempts to operate the operation means of the surface lattice by reaching out from the gap of the surface lattice from outside, the surface lattice cannot be opened, and the security property is very excellent. On the other hand, when a disaster such as a fire occurs on the indoor side, the operating rod is eccentric in the horizontal direction with respect to the locking bar so that the tip of the operating bar projects from the operating rod, and this operating bar is the same as the locking bar. When the operation bar is pulled while being positioned on the shaft, the insertion lock of the locking bar into the bar insertion locking hole is released. Therefore,
In this state, by moving one surface lattice body to the other side, one side of the frame of the sash is opened, so that a person in the room can escape from this open portion to the outside and evacuate, We can be spared from disasters such as fires.

[0010] The retrofitted grid (1) thus formed
Is easily fitted to an existing building sash (3) by fitting the fitting part (2a) to an extension part (4) extending in a direction parallel to the outermost window surface. Can be retrofitted without the need for Moreover,
When attaching the escape surface lattice at the time of new construction, an arbitrary window frame can be appropriately attached, and an arbitrary surface lattice can be easily attached to this window frame by retrofitting. Further, as the attached surface lattice main bodies (5a) and (5b), a sliding surface lattice is exemplified in the illustrated embodiment, but is not particularly limited in the present invention, and is arbitrary in combination with a window frame. From among the variations described above, for example, an arbitrary surface lattice such as a drop-down type or a pull-up type can be selected and attached.

Next, an embodiment of a retrofitting grid and an escape operation mechanism in the retrofitting grid according to the present invention will be described. In the above-mentioned retrofitted grid (1), a sash (3) is provided with a through hole (6) as shown in FIG. The through hole (6) is provided in the play space in the depth direction of the frame of the sash (3) in the wall width direction. This play space is a space for stopping the window glass door. A locking bar (10) is inserted through the through hole (6). The tip of the locking bar (10) is inserted and locked in a bar locking insertion hole (13) provided in the vertical frame (2).
The locking bar (10) can be moved toward the outside or the inside of the room by operating means to be described later.
The insertion lock into the device is maintained or released.

The other end of the locking bar (10) is shown in FIGS.
As shown in the figure, the structure is connected to the operation means (11). The operating means (11) includes an operating rod (17) composed of a vertical board (14), a protective cylinder pivotally supported on a shaft member (16) above the vertical substrate (14), and this protective cylinder. The operation bar (2) provided in the operation rod (17)
0) and a retaining plate (21). Operating rod (1
7) has a pointing arm (15) at its base, and this pointing arm (15) is pivotally attached to a vertical board (14) by a shaft member (16). The operation bar (20) has an L-shaped base having a long hole (19), and the protruding arm (22) of the engaging plate (21) is connected to the shaft (2) in the long hole (19).
It is pivoted through 3).

The engaging plate (21) is provided with a vertical substrate (14).
Is pivotally supported via a central shaft (26). Further, the engaging plate (21) is provided with a substantially hard guide hole (27) at a portion closer to the outdoor, and the shaft portion (28) at the end of the locking bar (10) is provided in the guide hole (27). Has been delivered. A long hole (24) is provided in the indoor end of the locking bar (10) along the axial direction thereof,
A guide shaft (25) projecting from the vertical board (14) is inserted into the elongated hole (24), and the locking bar (10) slides in the axial direction on the vertical board (14). It is configured to be.

A projecting arm (22) projects upward from a substantially central portion of the engaging plate (21), and a shaft (23) projects from the tip of the projecting arm (22). Has been established. The shaft (23) is disposed in the elongated hole (19) of the operation bar (20). Further, the engaging plate (21) is provided with a spring (2).
9), it is always urged counterclockwise about the axis (26). Further, in the present invention, a configuration in which the locking bar (10) is longer than the length of a human arm can be adopted. The reason for this is that, as will be described later, to release the surface grid (1), the operating rod (17) is locked by the locking bar (1).
When the operation bar (20) is positioned on the same axis as the locking bar (10), the tip of the operation bar (20) is made to protrude from the operation rod (17) by eccentricity in the horizontal direction with respect to 0). It is necessary to release the insertion lock of the locking bar (10) into the bar insertion hole (13) by pulling the operation bar (20), but the locking bar (10) is longer than the length of a human arm. If the length is set to a length, the operating bar (17) cannot be reached from the outside, so that the operating rod (17) cannot be reached. Therefore, the operating rod (17) cannot be decentered in the horizontal direction with respect to the locking bar (10). This is because the plane grating (1) cannot be opened. Alternatively, in the present invention, a configuration can be adopted in which the operation bar (20) is set to be longer than the length of a human arm. The reason for this is that even if the operation rod (17) is eccentrically eccentric from the outside to operate the projecting operation bar (20), the tip of the operation bar (20) cannot be reached, and as a result, the locking bar This is because the insertion lock of (10) cannot be released. further,
In the present invention, if the locking bar (10) and the operation bar (20) are both configured to have a length longer than the length of the arm of a person, it is a matter of course that the operation rod (1) is provided.
7) The reach of the tip of the operation bar (20), which is more protruding, cannot be reached, and the insertion and locking of the locking bar (10) cannot be released.
More preferred.

The use state of the locking bar (10) and the operating means (11) having the above configuration will be described in detail with reference to FIGS. First, as shown in FIG. 6, the operating rod (17) is
In a state of being perpendicular to the locking bar (10), the shaft portion (28) of the locking bar (10) is located at the upper indoor side end of the substantially heart-shaped guide hole (27) of the engaging plate (21). 31). Therefore, the locking bar (10) is connected to the operating rod (1).
7) is fixed so that it cannot be moved. Next, as shown in FIG. 7, the operating rod (17) is tilted to a position of 45 degrees with respect to the locking bar (10), and as shown in FIG. ), The operation bar (20) in the operation rod (17) is projected forward from the front end toward the indoor side due to a difference in the center of rotation (in an eccentric state). . In this state, when the operation bar (20) is pulled toward the room side as shown in FIG. 9, the locking bar (10) moves about 15 mm toward the room together with the operation bar (20). . By this movement, the tip of the locking bar (10) is disengaged from the bar insertion locking hole (13) provided in the surface lattice main bodies (5a) (5b), and the inserted locking state is released. Therefore, the screen lattice bodies (5a) and (5b) can be opened in the event of a disaster such as a fire, and a person inside can escape from the open portion to the outside.
