Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a sash door device with a surface lattice, which is suitable for crime prevention and evacuation, by attaching a sash door to a window opening and attaching a surface lattice to the outside thereof. .

(Prior Art) Conventionally, a plane lattice for escape and evacuation is known, and is disclosed in, for example, Japanese Utility Model Publication No. 59-13557. In addition, a surface lattice is disclosed in Japanese Utility Model Publication No. 59-167294. See also Kaisho 58
-156890.

(Problems to be solved by the invention) However, in the above-mentioned conventional surface lattice, the former is for evacuation because it has a structure in which a hinge is attached to one of the left and right sides and the hinge is used as a rotation axis to open and close. , There is no consideration for crime prevention. The middle is a plane lattice that moves in the vertical direction, the structure for moving is complicated, and consideration for locking for crime prevention is also lacking. Further, the latter requires a certain space because the opening and closing structure of the surface lattice is the structure that opens outward with the vertical axis as the rotation axis, like the former, and the locking mechanism for crime prevention is the vertical frame of the surface lattice. The operation is complicated because it requires a two-step process in which the tip engaging portion of the L-shaped connecting rod is inserted into and removed from the holes provided in the inner member of the metal fitting and the receiving metal member so that the tip engaging portion can be inserted and removed, and pulled out in and out. . Especially, the configuration is not sufficient as an operation when looking up during evacuation.

(Means for Solving the Problems) The present invention solves the above-mentioned drawbacks. Its feature is a pair of surface lattices consisting of a fixed surface lattice that is housed in a frame body consisting of a lower frame and left and right vertical frames that have a concave cross-section that also serves as a rail, and a surface lattice that can be opened and closed in the left-right direction. , A pair of sash doors that are housed in a door stop are attached to the outside of the sash door at a predetermined interval, and the pair of sash doors are openably and closably attached to the inside of the surface lattice of the sash door. A lock portion having a hook engaging hole is attached to the vertical rail so as to project toward the vertical frame, and a lock portion is attached to the vertical frame opposite the vertical rail of the surface lattice. The locking part is integral with the engaging part that engages with and disengages from the key engaging hole of the locking part and the engaging part via a connecting tool, and is vertically moved via the mounting tool attached to the vertical frame. It is composed of an operation lever that is rotatably attached, and the operation lever is When the sash door corresponding to the child is in the closed state, the end of the operation lever contacts the sash door to maintain the locked state, and when the sash door is in the open state, the operation lever rotates in the horizontal direction to unlock. The lock mechanism that holds the state and further prevents the movement of the sash door alone is formed at a position corresponding to the locked part of the above-mentioned surface lattice and keeps the closed state, corresponding to the above-mentioned fixed surface lattice. A sash door device with a surface lattice, in which the sash door in use is kept open.

(Operation) According to the above configuration, the sash door device with the surface lattice is excellent not only for evacuation but also for crime prevention.

(Embodiment) FIGS. 1 and 2 show an embodiment of the surface lattice of the present invention. The pair of surface lattices 1 and 2 are composed of vertical pipe-shaped vertical bars and horizontal bars.
One surface grating 1 (right side) is a fixed surface grating, and the other surface grating 2 (left side) is openable / closable in the left-right direction. As shown in the figure, the surface lattices 1 and 2 also serve as rails, and are housed in a frame body composed of lower frames 3 and 4 and left and right vertical frames 5 and 6. As the fixing means of the surface lattice 2, the vertical bars 1a and 1a are fixed to the upper and lower frames 3 and 4 and the vertical frame 5 which also function as rails and have a concave cross section, but they may be appropriately fixed. Also, the end of the horizontal rail 2b of the openable grid 2 is inserted into one vertical rail 1a, and when the horizontal grid 2 is opened, four horizontal rails 1b are opened.
... is inserted. The surface lattice 2 has a sliding member 17 at the lower end of the vertical bar 2a.
Is attached to the rail 4 so that the rail 4 can easily slide on the upper surface. In FIG. 1, the surface lattice 2 is shown partially open, and a hook engaging portion 18 is provided at the tip of the vertical bar 2a.
Is installed. That is, a locking portion 18 having a key engaging hole 18a is formed at the end of the surface lattice at the middle of the vertical bar 2a in the height direction so as to project toward the vertical frame 6 side. 19 is a vertical bar 2a of the area lattice
It is a locked portion provided on the vertical frame 6 opposite to the above. The locking mechanism is constituted by this and the locking portion, and locking and unlocking of the key is established. Reference numeral 19a is an operation lever which constitutes a part of the locked portion. Of course, the terms locked and locked may be reversed.

FIG. 3 is an explanatory view of the locking mechanism. FIG. 3B shows the unlocked state, that is, the operation lever 19a is rotated horizontally. In FIG. 3A, the operation lever is vertically erected, and this state shows the locked state. To unlock the door, that is, to unlock it, open the sash door (glass sliding door) at the opening of the house in advance and rotate the operation lever to a position where it can be kept horizontal without touching the sash door. It can be achieved by opening. That is, normally, when the glass sliding door is closed, the operating lever is caught on the frame of the sliding door or the glass and is not laid down further, that is, is not horizontal, but remains in the locked state. In this way, the area lattice is not opened, which contributes to the crime prevention effect. In other words, unlocking is performed by opening the sash door facing the surface lattice provided with the locking mechanism. Also, this locking mechanism is extremely simple and easy to operate. In the locking mechanism shown in FIG. 3C, the operating lever 19a is integral with the triangular engaging portion 19c and the connecting metal fitting 19d, and is rotated in the vertical direction via the axis of the fixture 19b attached to the vertical frame 6. It is movably attached. If you open the sash door and rotate this operating lever about 90 degrees, the triangular engaging part 19c
However, it is released from the engagement hole 18a of the key, the engagement with the locking portion 18 is released, and the lock is released. Reference numeral 6a is a cutout hole cut out on one side of the vertical frame. Reference numeral 20 denotes a sash door that fits in the door stop, and a pair of sash doors 21 are formed. The sash doors 21 are formed at a predetermined interval with the surface lattices located outside of the sash door, and the interval is 5
15 cm is preferred.

FIG. 4 is a schematic plan view of the sash door device of the present invention.
On the outside, there is a pair of surface gratings (openable and closable surface grating 1 and fixed surface grating 2), and on the inside there is a pair of corresponding openable and closable surface grating and fixed surface grating. The lower rail of the sash door, 22 is a locking part attached to the side of the above surface lattice corresponding to the locked portion 19 of the lower rail, and the key portion 23 of the sash door 20 corresponding to the openable and closable surface lattice 1. Locked part 24 provided at a position corresponding to the above-mentioned locked part 22 of the lower frame
It is configured to appear and disappear freely. Therefore, since the sash door locking mechanism is provided at the end of the sash door at the position corresponding to the locked portion 19 of the surface lattice, the sash door can be locked and unlocked by itself. Of course, the other sash door can be opened and closed. Further, it goes without saying that a crescent lock, for example, for locking both sash doors can be provided in the same manner as in the conventional case. That is, a locking mechanism is formed to prevent the movement of the sash door alone. A publicly known technique can be adopted for this locking mechanism.
26 and 26 are door-stops, and 27 and 27 are covering frames for the area lattice.

The present invention is not limited to the above-described embodiments, but all the things included in the technical idea of the present invention are applicable.

(Effect) According to the present invention, the locking mechanism of the openable and closable surface lattice is made with an extremely simple structure, that is, the locking mechanism that can be locked and unlocked securely by simply rotating the operating lever in the vertical direction. In addition, the sash door corresponding to it also has a locking mechanism that prevents the sash door from moving independently.The above-mentioned surface lattice keeps the locked state by the operating lever of the locking mechanism contacting the sash door when the sash door is closed. Therefore, it is excellent in crime prevention. If the sash door is locked, the locked state of the surface lattice can be maintained even when the other sash door is opened, so that the crime prevention effect can be exerted while introducing air from the outside. When opening the surface lattice, unlock the sash door to open the sash door, and further rotate the operation lever to unlock the surface lattice and open the surface lattice, thus providing an evacuation effect. To do.
