Description

[Detailed description of the invention] The present invention is a locking metal fitting for a rotating window, which consists of a supporting shaft protruding and fixed to the window mounting frame, and a receiving metal fitting that is attached to the rotating window and has a built-in mechanism for rotating and fixing the rotating window. It is related to.

Conventionally, this type of locking hardware for a rotating window has been constructed by supporting the rotating window rotatably on the window mounting frame with a dedicated rotating hardware that rotates the rotating window, and by attaching a fixing hardware with a rod that slides as the rotating window rotates separately from the rotating hardware and at a different position, and when fixing the rotating window at the desired opening angle, the rod of the fixing hardware is tightened with a screw, etc. However, tightening the screw, etc. is troublesome, and the appearance is poor because a relatively long rod, etc. is used, and there are also disadvantages that the rod is prone to bending or breaking.

In view of these drawbacks, it is an object of the present invention to provide a locking fitting for a rotating window which integrates a rotating fitting and a fixing fitting and which allows the rotating window to be fixed with a simple operation.

That is, in the rotating window locking fitting according to the present invention, a support shaft is provided inwardly protruding from the window mounting frame, and a support shaft is provided at a position corresponding to the position of the support shaft of the rotating window that fits into the window mounting frame. A metal fitting is provided, and the rotary window is rotatably supported in the window mounting frame by coupling a gear rotatably installed in the housing of the receiving metal fitting to the support shaft, and the rotary window is rotatably supported in the window mounting frame. A stopper having teeth that mesh with the teeth of the gear is installed so as to be slidable in the direction of meshing or disengaging with the gear, and a sliding plate is fitted to the stopper so as to be non-removable and slidable, and the sliding plate is slidably fitted to the stopper. A biasing member is interposed between the plate and the stopper, and a French drop whose operating shaft slides when the lever is swung can be operated by swinging from outside the receiving metal fitting, and the operating shaft can be moved from outside the receiving metal fitting. The actuating shaft is disposed in a housing, and the operating shaft and the sliding plate are connected, and the teeth of the stopper are engaged between the teeth of the gear via the biasing member by operating a French drop lever to appropriately open the rotating window. It is constructed so that it can be fixed at a corner.

This will be explained below based on the illustrated embodiments.

The window mounting frame 1 has a support shaft protruding inwardly (toward the opening side, that is, the rotating window 3 fitting space side) approximately at the center of the upper and lower horizontal frames, and the rotating shaft that fits into the window mounting frame 1 The window 3 is rotatably supported by the support shaft.

The locking fitting for a revolving window according to the present invention includes a window mounting frame 1
Tapered shaft 2 as a support shaft protruding from the lower frame of
and a receiving metal fitting 4 attached to the rotating window 3.

A tapered shaft 2 protruding from the lower frame of the window mounting frame 1
is integrally planted via a pedestal 2c on a mounting plate 2b that is fitted into the window mounting frame 1 and fixed with screws 2a.

A metal fitting 4 is fixed to the position of the rotating window 3 corresponding to the tapered shaft 2 (i.e., approximately the center of the lower frame of the rotating window 3). The metal fitting 4 is a U-shaped lower housing 5 and a frame body 3a of the rotating window 3.
The mounting plate 6 and the lower housing 5 are fixed to the
A gear 8, a stopper 9, a coil spring 10, a sliding plate 11, etc. are disposed at predetermined positions inside the housing.

The gear 8 is rotatably supported by the upper and lower housings 5 and 7, and the gear 8 is formed into a tapered shaft by fitting and fixing the tapered shaft 2 protruding from the lower frame of the window mounting frame 1 into the square taper hole 8a. It is attached to the shaft end of No. 2 so that it cannot rotate relative to it.

A stopper 9 that meshes with the gear 8 to fix the rotary window 3 has teeth 9a cut in its tip that mesh with the gear 8, and a coil spring 10 is compressed and inserted onto the stopper shaft 9a at the rear, and this stopper shaft 9b A sliding plate 11 whose rear end is U-shaped in plan view.
It is configured such that one side of the fixing pin 12 is provided with a penetrating shaft, and a fixing pin 12 is externally fitted onto the penetrating end.

The sliding plate 11 is integrated with the stopper 9 and the coil spring 10 and can slide within the housing. The other side of this sliding plate 11 has a U-shaped groove 11a into which the operating shaft 14 of the French drop 13 is fitted.
is cut out.

In the French drop 13, the operating shaft 14 slides back and forth by the swinging operation of the operating lever (the operating shaft 14 retracts when the operating lever is raised, and the operating shaft 14 protrudes when the operating lever is pushed down). . This French drop 13 is attached to the housings 5 and 7 of the bracket 4 and is removably set on the window frame with screws, etc., and its operating shaft 14 is inserted into the bracket 4 through the opening of the bracket 4. Actuation axis 1
4 is fitted with the sliding plate 11, so that the sliding plate 11 can be slid by sliding the operating shaft 14.

In the rotary window lock fitting configured as described above, when the operating lever of the French lock 13 is pushed down, the stopper 9 is pressed and biased via the sliding plate 11 and the coil spring 10, so that its teeth 9a engage with the gear 8. They mesh to prevent the stopper 9 (i.e., the receiving metal fitting 4) and the gear 8 from rotating relative to each other, thereby restricting (i.e., fixing) rotation of the rotary window 3.

And the rotation of the rotating window 3 is the French drop 13.
This is possible by raising the operating lever.

When the operating lever of the French drop 13 is raised, its operating shaft 14 is retracted, and the stopper 9 is moved from the sliding plate 1.
1. It is pulled and slid through the fixing pin 12, and the meshing state between the gear 8 and the teeth 9a of the stopper 9 is released as shown in FIG. Therefore, the gear 8 and the holder 4 cannot rotate relative to each other, and the rotating window 3 can therefore rotate.

In this state, the rotary window 3 is rotated to a desired position, and the swing lever of the French drop 13 is operated (tilted) to cause the operating shaft 14 to protrude as shown in FIG. As a result, the stopper 9 is pressed in the direction of the gear 8 via the coil spring 10, and its teeth 9a mesh with the gear 8 as shown in Figure 7, restricting the rotation of the gear 8 and making the rotating window 3 unrotatable. Fix it. still,
At this time, even if the gear 8 and the teeth 9a of the stopper 9 are not completely meshed, the urging force of the coil spring 10 presses the stopper 9 toward the gear 8, and the rotary window 3 is brought into a completely meshed state. can be fixed.

As described above, according to the locking fitting for a rotating window according to the present invention, the rotating fitting and the fixed fitting are compactly integrated without using a long rod. It can be mass-produced quickly, and fixing and unfixing can be performed extremely easily using the French drop 13.
