Description

[Detailed explanation of the idea] This invention relates to a locking device.

A lighting window to which a conventional locking device A is applied will be explained with reference to FIGS. 1 to 7. That is, as shown in FIG. 1, this daylighting window has an opening frame consisting of an opening base frame 3 and an opening upper frame 4 attached to the periphery of the opening 2 of the roof base material 1, and a window frame in which the glass 5 is fitted. A locking device A is provided on the open end side of the window frame 6, with one end of the window frame 6 attached to the outdoor side with a hinge 7 so as to be freely openable and closable.
This locks and unlocks the door.

To explain in detail the structure of the locking device A, as shown in FIG.
As shown in FIG. 3, the hook holders 8 with which the hooks b are hung are attached at two locations (one not shown) on the inner surface of both ends of the opening base frame 3 on the open end side of the window frame. Further, a long mounting auxiliary plate 9 is fixed along the lower surface of the open end side of the window frame 6 with bolts 10 and nuts 11, and a long mounting auxiliary plate 9 is attached to both ends of the lower surface of the protruding portions 9a at both ends of the mounting auxiliary plate 9, as shown in FIG. and a pair of L as shown in FIG.
The shaped fittings 12 and 13 are attached by caulking pins 14 so as to face each other. Then, a shaft pin 15 is spanned between these two L-shaped fittings 12 and 13 to pivotally connect a hook 16 in the shape of an "E", and as shown in FIG. A tension coil spring 19 is tensioned through the pins 17 and 18 to urge the hook 16 to rotate clockwise in FIG. The hook portion 16a is engaged with the horizontal shaft 8b to enable locking. On the other hand, as shown in FIG. 4 and FIG. It is pivotally connected to the collar 13a by a rotating shaft 23.
In this case, as shown in FIG.
It is located between the other end 16b of the L-shaped fitting 13 and the hook 16, and in its natural state, the push-up bar 20 contacts the rear end surface 13b of the L-shaped fitting 13, and is rotated clockwise in FIG. 3 by the tension coil spring 19. Forced hook 1
When the other end 16b of the hook 16 is forcibly pushed up in the counterclockwise direction in FIG.
Rotate counterclockwise around the fulcrum to release the hook part 16.
a is removed from the horizontal shaft 8b to enable unlocking.
24 is a spacer pin of both L-shaped metal fittings 12 and 13.

The window frame 6 is constructed by attaching a connecting member 6c to the lower surface of the window frame main body 6a via a heat insulating sheet 6b with screws 6d, and a base material is inserted into the recess formed by the connecting member 6c and the window frame main body 6a. Glass 5 is attached via 21' and sealant 22'.

To unlock a locked lighting window, as shown in FIG. When the rod 20 is pushed upward, the hook 16 rotates counterclockwise in FIG.
The lock is released, and the window frame 6 can be opened to the outside. Conversely, when closing the window frame 6, the operating portion 25a of the operating rod 25 may be hooked onto the push-up rod 20 and pulled into the room. FIG. 6 shows the process in which the hook 16 automatically locks and locks the horizontal shaft 8b when the window frame 6 is pulled into the room.
That is, when the window frame 6 is closed, the left inclined portion of the outer peripheral surface of the hook portion 16a of the hook 16 comes into contact with the horizontal shaft 8b as shown in FIG. 6a, and then as shown in FIG. 6b. The outer peripheral surface of the hook part 16a is the horizontal axis 8
When the hook 16 is rotated clockwise and lowered by the pusher b, and the window frame 6 is closed, the hook 16a is moved to the sixth position by the biasing force of the tension coil spring 19, as shown in FIG. 6c. Move to the left direction in the figure and hook part 16
It is automatically locked by locking the inner peripheral surface of a to the lower surface of the horizontal shaft 8b.

However, as shown in FIG. 7, if the hook 16 is installed deviated from the normal position B toward the left in FIG. 7 due to an assembly error or the like, when the window frame 6 is closed, This has the drawback that the lower end of the surface is lifted up on the horizontal shaft 8b, and the hook 16 cannot be rotated counterclockwise in FIG. 7, that is, it cannot be locked.

Therefore, the object of this invention is to provide a locking device that can lock a casement window even if there is some assembly error.

An embodiment of this invention will be described with reference to FIGS. 8 to 10. That is, this locking device uses a hook holder 26 shown in FIGS. 8 and 9 in place of the hook holder 8 shown in FIG. 2. This hook holder 26 is connected to both side pieces 27 of a substantially U-shaped bearing 27.
Horizontal shaft holes 28 are drilled opposite to each other in a, and this horizontal shaft hole 2
Both ends of a horizontal shaft 29 having a shaft diameter smaller than the hole diameter of No. 8 are loosely fitted into the horizontal shaft hole 28, and both ends 29a
It is crimped to prevent it from coming out. This hook holder 26 is fixed to the inner circumferential surface of the opening base frame 3 in place of the hook holder 8 shown in FIG. The center piece 27b is fixed to the opening base frame 3. The other configurations are the same as those of the locking device A described above.

As a result of this configuration, as shown in FIG. 10, even if the hook 16 is installed leftward from its normal position due to an assembly error or the like, the lock can be automatically locked in the following manner. That is, as shown in FIG.
is loosely fitted into the horizontal shaft hole 28, so the horizontal shaft 29 is pressed against the outer peripheral surface of the hook portion 16a and moves to the left, as shown in FIG. When the window frame 6 is closed as shown in FIG. 3) moves to the right in FIG. 10, and the hook part 16
The lower surface side of the horizontal shaft 29 is engaged with the inner circumferential surface of a and is automatically locked.

Note that this invention is applicable not only to daylight windows but also to the locking part of general casement windows.

As described above, the locking device of this invention includes a bearing tool having a horizontal shaft hole, a horizontal shaft loosely fitted into the horizontal shaft hole, and a horizontal shaft that is approached from above and moved horizontally toward the tip side. As the casement window has a hook, the outer circumferential surface is pressed against the horizontal axis and retreats, the tip moves forward passing under the horizontal axis, and the inner circumferential surface engages with the horizontal axis, so there may be some assembly errors in the casement window. It also has the effect of being able to be locked.
