Description

[Detailed explanation of the idea] This invention relates to a locking mechanism for a casement window.

Generally, a casement window is installed on the outdoor side of the opening frame, with the window glass fitted into a groove on the inner peripheral surface of the window frame through a sealant.
A locking mechanism that locks the window frame in a state in which the window frame is attracted to the opening frame by locking an engaging claw pivotally connected to the interior side of the open end of the window frame to a claw locking portion provided on the inner peripheral surface of the opening frame. When closing and locking the window frame, a concentrated tensile force is applied in the direction of expanding the window frame groove, causing the sealing material in the groove to tensilely break.
There was a problem that the rain closure was impaired.

Therefore, an object of this invention is to provide a locking mechanism for a casement window that can prevent the sealing material from breaking.

An embodiment of this invention will be described with reference to FIGS. 1 to 6.

That is, as shown in FIG. 1, this casement window locking mechanism A) attaches an opening frame consisting of an opening base frame 3 and an opening upper frame 4 to the periphery of an opening 2 of a roof base material 1, and also attaches a glass 5. This is applied to a daylighting window in which one end of a fitted window frame 6 is pivotally connected to the outdoor side by a hinge 7 so as to be freely openable and closable.

As shown in FIG. 2, the window frame 6 is constructed by attaching a connecting plate 6C to the lower surface of the window frame body 6a via a base material 6b with screws 6d, and is formed by the connecting plate 6C and the window frame body 6a. Glass 5 is fitted into groove 8 on the inner circumferential surface of the window frame with base material 9 and sealant 10 interposed therebetween.

Further, a bolt 11 is attached to the lower surface of the connecting plate 6C of the window frame 6.
and nuts 12 to fix the auxiliary mounting plate 13.

In this case, as shown in FIG. 3, the auxiliary mounting plate 13 has a window frame contact portion 13a along the lower surface of the grooved portion 6e of the connecting plate 6C, and a window frame contact portion 13a that faces inward at both ends of the window frame contact portion 13a. The window frame contact portion 13a is provided with a bolt insertion hole 13C, and the board attachment portion 13b is provided with a caulking pin insertion hole 13d.

The attachment to the window frame 6 is performed by fitting the bolt head of the bolt 11 into the groove of the window frame open end groove 6e of the connecting plate 6C, and then attaching the window frame contact portion 13a to the lower surface of the groove 6e. This is done by passing the shaft portion of the bolt 11 into the bolt insertion hole 13C in close contact with the bolt 11, and fastening the nut 12 to the bolt 11 from below.

On the other hand, on the lower surface of the board mounting portion 13b, there is a pair of L-shaped fittings 16.1 that pivotally support the engagement claw 14 and the engagement claw operation bundle 15.
The board 18 to which 7 is attached is fixed by caulking with caulking pins 19 as shown in FIG.

In this case, the crimping pins 19 are inserted into the pin insertion holes 13 (1, 18a) provided in the board mounting portion 13b of the auxiliary mounting plate 13, and the horizontal pieces of the board 185 and the carving tools 16 and 17, respectively.

The engaging pawl 14 is connected to the rotating shaft 20 (Fig. 2), which is passed between the two carved metal fittings 16 and 17 and has an axial direction in the same direction as the pivot axis of the hinge 7 (Fig. 1). Pivotally supported, L carved metal fittings 1
A compression coil spring 21 stretched between the main body 7 and the main body 7 rotates in the second rotational direction.

Further, the operation bundle 15 is constructed by connecting a bar-shaped horizontal side 15a and an arm-shaped vertical side 15b in a U-shape, and the upper ends of both vertical sides 15b are connected to a double-carved metal fitting 17 (see FIG. 4). A hanging piece 17 a formed by bending the tip of the horizontal piece downward is pivotally connected by a rotating shaft 22 , and its horizontal side 15 a is arranged below the locking pawl 14 , and the operation bundle 15 is attached to the rotating shaft 22 .
By rotating counterclockwise in Figure 2 using 2 as a fulcrum,
One end 14a of the engagement claw 14 is pushed up by the horizontal side 15a, and the engagement claw 14 can be rotated counterclockwise about the rotating shaft 20 against the spring 21.

Furthermore, a four part 23 is provided on the inner surface of the opening frame 3 at a position facing both the engaging claws 14, and the claw part 1 of the engaging claw 14 is provided therein.
Attach the rod-shaped claw locking portion 24 that can be engaged with the screws 4b.

Locking and unlocking of the window frame 6 by the casement window locking mechanism A is performed as follows.

First, in FIG.
0 as a fulcrum, and the claw portion 14b is in a locked state engaged with the claw locking portion 24.

To unlock this, as shown in FIG. 1, lift the bundle operating rod 25 from the indoor side through the opening 2, and as shown in FIG. Push up the horizontal side 15a.

Then, the operation bundle 15 rotates in the counterclockwise direction in FIG.
engages one end 14a of the engaging claw 14, and the engaging claw 14
rotates in the same counterclockwise direction about the rotating shaft 20 as a fulcrum, and the claw portion 14b of the locking pawl 14 is disengaged from the pawl locking portion 24 to be unlocked.

On the other hand, to lock the lock, perform the operation in the reverse order as described above, that is, as shown in FIG.
are rotated in the same direction using the biasing force of the spring 21 to engage the claw portion 14b with the claw locking portion 24.

In this case, if the board 18 that supports the locking pawl 14 and the operation bundle 15 is attached directly to the groove 6e of the window frame 6, the force generated when the operation bundle 15 is pulled down will be applied to the groove 6e. The effect is concentrated on the window bonding portion of the substrate 18 of 6e, and the sealing material 10 above the tightly bonded portion is tensilely broken. Since it is attached to the window frame 6 via the auxiliary attachment plate 13 that is brought into close contact over a wide area, the force generated when the operation bundle 15 is pulled down acts in a distributed manner over the entire groove-shaped portion 6e, and the sealing material 10 will not break under tension.

Further, even when the door is locked, a force is generated by the spring 21 that presses the window frame 6 against the opening upper frame 4 and tensilely breaks the sealant 10, but this force is also dispersed and acts on the sealant 10 by the auxiliary mounting plate 13. To do this, sealant 1
0 will not be tensile broken.

In this way, since the board 18 that supports the engaging claw 14 and the operating bundle 15 is attached to the window frame 6 via the auxiliary mounting plate 13, the force generated when pulling down the operating bundle 15 and during locking is applied to the sealing material 10. Distribute and act,
This tensile breakage can be prevented.

Furthermore, since the board 18 is fixed to the auxiliary mounting plate 13 with caulking pins 19, the board 18 can be mounted in a predetermined position with high precision, and the engaging claws 14 can be engaged with the claw locking portions 24 with high precision. Can be locked.

In addition, in the above embodiment, the engaging claw 14 and the claw locking portion 2
I installed a pair of 4 and locked it in two places, but 1
It may be locked separately.

Furthermore, the setting position of the board mounting portion 13b of the auxiliary mounting plate 13 is not particularly limited, and may be provided, for example, at the center of the window frame contact portion 13a.

As described above, the casement window locking mechanism of this invention allows the casement window frame, in which the opening closing plate is fitted into the groove formed on the inner peripheral surface of the window frame through the sealant, to be freely opened and closed on the outdoor side of the opening frame. A claw locking portion is provided inside the opening frame on the open end side of the window frame, and a mounting bracket that pivotally supports the engagement claw and the engagement claw operation bundle is attached to the lower surface of the open end side of the window frame. , in a casement window locking mechanism in which the engagement claw is rotated to engage and release from the claw locking portion by pulling and pushing the operation bundle from the indoor side, the mounting bracket is attached to the open end of the window frame; Since it is attached to the window frame via the auxiliary attachment plate that is brought into close contact over a wide area of the lower side surface, there is an effect that the sealing material can be prevented from breaking.
