BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Figure 1 shows the skylight 1
2 is a view from the indoor side of FIG. 2, and FIG. 2 is a view taken along the line II-II of FIG.

As shown in FIGS. 1 and 2, the dead-fitting skylight 1 is a base frame 2 fixedly installed in the opening H of the roof and a detachable installation on the outdoor side of the base frame 2. And the window frame 3 to be displayed. In the illustrated example, fixed locking metal fittings 5, 5, ...
The window frame 3 is detachably fixed to the base frame 2 by a window frame fixing metal fitting 4 including a lock 6 provided at the center of four sides of the base frame 2. In the illustrated example, the window type is a dead-fitting window, and the glass G is installed on the window frame 3 through the Grechan 20.

More specifically, as shown in FIG. 2, the window frame 3 is provided with an upright wall 3a along the longitudinal direction of the member on the inner side surface of the frame body 3A and at a position closer to the inner side of the frame. Further, fixed locking metal fittings 5, 5, ... Are provided on the outer side surface of the frame of the standing wall 3a and at the center position of each side.

On the other hand, as shown in the same figure, the base frame 2 is provided with a standing wall 2a along the longitudinal direction of the member at a position on the outdoor side surface of the frame body 2A and on the outer side of the frame. The locks 6, 6 ... Are provided on the inner side surface of the frame 2a and at the center position of each side.

In order to attach the window frame 3 to the base frame 2, the window frame 3 is positioned from the outside and the base frame 2 is aligned, and the window frame 3 is dropped toward the indoor side, so that the standing wall 3a of the window frame 3 is removed. The upright wall 2a portion of the base frame 2 is fitted together, and the fixed lock fittings 5, 5 ... Attached to the window frame 3 side are attached to the base frame 2 side.
6 are automatically engaged and fixed so as not to be detachable unless an unlocking operation described later is performed.

Fixed locking member 5 attached to the window frame 3
As shown in detail in FIGS. 3 and 4, the case 10 has a substantially U-shaped cross section, a lock piece 11 swingably supported by a support shaft 15 in the case, and the lock piece 11. A locking rocking piece 12 that holds the lock piece 11 in a locked state by engagement with 11, and an unlocking operation that unlocks the locking piece 11 by rocking the locking rocking piece 12 by a screwdriver. The locking piece 11 is interposed between the piece 13, the locking piece 11 and the locking rocking piece 12 to urge the locking piece 11 in the unlocking direction (counterclockwise direction), and the locking rocking piece 12 is moved to the locking piece. It is mainly composed of a spring plate 14 for urging the contact plate 11 to the contact side.

The case 10 is a member formed by bending a metal plate material into a substantially inverted U-shaped cross section, and has three corners.
Through holes 17, 17 are formed so as to penetrate the spots and the plate surface, and are fixed to the standing wall 3a of the window frame 3 by fixing screws 21, 21, .... Further, a U-shaped lock pin fitting groove 10a is formed on the lower end side of the case 10.

The lock piece 11 is a member swingably supported by a support shaft 15, and is composed of a short projecting piece 11a located relatively on the lower side and a long projecting piece 11b located on the relatively upper side. U-shaped groove 1 into which a lock pin 18 described later is fitted
1c is formed. In addition, an unlocking engagement step portion 11d is formed on the periphery of the locking rocking piece 12 side, a locking engagement step portion 11e is formed, and a spring locking portion 11f is provided on the upper side. Has been formed.

On the other hand, the locking rocking piece 12 is a member which is rockably supported by a support shaft 16, and has an engaging portion for holding the lock piece 11 in a locked state at the peripheral edge on the lock piece disposing side. The protrusion 12a is formed, the rocking operation cam surface 12b is formed, and the spring locking portion 12 is formed on the upper side.
c is formed.

The unlocking operation piece 13 is the locking swing piece 1.
The lockable rocking piece 1 is rockably provided at a position adjacent to the lock locking rocking piece 1.
2 is a convex surface 13a that comes into contact with the rocking operation cam surface 12b, and a screwdriver engaging groove 1 is provided on the end surface of the shaft portion exposed from the case 10.
3b is formed.

Between the lock piece 11 and the locking rocking piece 12, the spring locking part 11f of the lock piece 11 is used as one end side locking part, and the spring locking part 12c of the locking rocking piece 12 is provided. As the other end side locking portion, the lock piece 11 and the locking rocking piece 12
A spring plate 14 curved in an arc shape is interposed between and, and the lock piece 11 is biased in a counterclockwise direction (unlocking direction) about the support shaft 15. At the same time, the locking rocking piece 12 is urged in the clockwise direction (abutting direction to the lock piece 11) around the support shaft 16.

As shown in FIG. 3, when the fixed lock member 5 is attached to the upright wall 3a, a screwdriver is inserted through a through hole 3b formed in the upright wall 3a to lock the unlocking operation piece 13. It is designed to be rotated and unlocked. The through hole 3b is normally closed by a cap 19.

On the other hand, a lock 6 fixed to the base frame 2
As shown in FIG. 7, is a member in which a lock pin 18 is integrally fixed to one side surface of a fixed plate 6a having screw holes 6b and 6b formed in the plate surface.

When the window frame 3 is attached to the base frame 2,
When the window frame 3 is pushed from the outdoor side to the base frame 2 side, the lock pin 18 enters the lock pin fitting groove 10a of the case 10 and collides with the long protrusion 11b of the lock piece 11. When the lock pin 11 is further lowered, the lock pin 11 is rotated clockwise while the lock pin 1 is rotated as shown in FIG.
8 penetrates into the deep part of the lock pin fitting groove 10a, and as the lock piece 11 rotates, the engaging projection 12a of the locking rocking piece 12 engages with the locking step 11e of the locking piece 11.
To prevent the locking piece 11 from returning,
The lock pin fitting groove 10a by the short protruding piece 11a of No. 1
It is held so that it does not come out. A caulking 22 is filled in the outer joint portion between the window frame 3 and the base frame 2 in order to ensure watertightness.

After that, in order to change the window type from the current fit-and-kill window to the open / close window, when removing the window frame 3, FIG.
When the unlocking operation piece 13 is rotated in the counterclockwise direction from the state shown in (1), the locking rocking piece 12 is rocked counterclockwise against the biasing force of the spring plate 14 and separated from the lock piece 11. By doing so, the engagement is released, the lock piece 11 swings in the unlocking direction (counterclockwise direction) by the biasing force of the spring plate 14, the lock pin 18 is released from the lock pin fitting groove 10a, and the window frame 3 Can be removed to the upper side.

By the way, in the above embodiment, the fixed lock member 5 is arranged on the side of the window frame 3 and the lock 6 is arranged on the side of the base frame 2. However, the relationship is reversed, and the lock 6 on the window frame 3 is arranged. Alternatively, the fixed lock members 5 may be arranged on the base frame 2, respectively. Further, although the window frame fixing fittings 4 are provided at one location on each side in the present embodiment, a plurality of window frame fastening fittings 4 may be provided on each side.

[0024]

As described above in detail, according to the present invention, since the window frame is detachably installed to the base frame fixedly installed in the opening, the window frame can be easily replaced. The window type can be easily changed after installation.
