Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a window opening/closing device, particularly a locking device thereof.

BACKGROUND ART Conventionally, casement windows, vertical rotating windows, vertical sliding windows, etc. all have handles for opening, closing, and locking the windows on the door edge side of the windows. Therefore, when opening or closing a window, as shown in Figure 1, it is necessary to make an incomplete movement by leaning forward with your upper body and operating the handle, which is extremely dangerous especially in the case of a bay window because there is a shelf under your feet. It had the disadvantage of being.

Problems to be Solved by the Invention This invention was made in order to eliminate these conventional drawbacks, and its purpose is to provide an opening/closing device that can safely open and close windows. .

Means for Solving the Problems The gist of the present invention to achieve the above object is to provide a handle on the hanging base side of the window, that is, the rotation center side when opening and closing the window, and to provide a locking hardware on the door end side of the window. A connecting rod is disposed through a connecting member, and the connecting rod is moved in the front and rear directions as appropriate by rotating the handle, and locking and unlocking operations are performed in conjunction with the locking hardware. A movable opening fixing rod is arranged via a connecting member, and an adjuster clamping part is formed at the tip, and a rod-shaped opening regulator such as a flexible tube has one end fixed to the window frame and passed through the adjuster clamping part. It is positioned at the bottom of the window and is configured to slide inside the gripping part when opening and closing the window, and when the desired opening degree is reached, the adjuster in the gripping part is clamped and fixed by rotating the handle, thereby fixing the window. A window opening/closing device is characterized by:

Function As described above, in the window opening/closing device of the present invention, by rotating the handle provided on the hanging base side of the window, that is, the rotation center side when opening/closing the window, by a predetermined angle, the connecting rod can be moved forward ( Since the window moves backward (or backward) and locks (or unlocks) in conjunction with the locking hardware, the window can be opened, closed, and locked by operating the handle on the hanging base. The handle is within easy reach even when the window is closed, making opening and closing operations extremely safe. In addition, if the handle is rotated by a predetermined angle to the desired opening with the window open, the opening fixing rod will move forward via the connecting member, and the adjuster clamping part at the tip will move the inside of the clamping part. Since the sliding rod-shaped opening adjuster, such as a flexible tube, is clamped and fixed, the window can be fixed at that angle, and the window can be opened, closed, and fixed by a series of handle operations. In addition, when you want to change the opening degree of the window or close the window, if you rotate the handle in the opposite direction and return it to its original state, the clamping state of the regulator clamping part will be released and the opening adjuster will move inside the clamping part. Since it slides freely and the gap between the window frame and the holding part can be set arbitrarily, the opening and closing operations of the window can be performed smoothly without any hindrance.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in Fig. 2, the handle 2 of the window 1 is provided on the hanging base side on the indoor side of the window, that is, on the side that is the center of rotation when opening and closing the window. 3 moves upward (forward), and the upper connecting rod 5 moves leftward (forward) via the upper corner connecting member 4 made of a flexible member, etc. The movement of the connecting rod is transmitted to the upper locking hardware 6 so that the upper rod 7 is protruded and locked.

In addition, there is a handle 2 on the lower side of the window as well as on the upper side of the window.
As a result of the rotation, the falling connecting rod 8 moves downward (forward), and the lower connecting rod 10 moves to the left (forward) via the lower corner connecting member 9 made of a flexible member or the like.
The movement of the connecting rod is transmitted to a lower locking hardware 11 provided at the lower part of the window on the door edge side, so that the lower rod 12 protrudes and is locked.

Further, when the vertical length of the window becomes large, the door end side connecting rods 13, 13 connected to one end of the upper locking hardware 6 and the lower locking hardware 11 move upward and downward, and the door end side center of the window is moved upward and downward. The movement of the connecting rod is transmitted to a locking hardware 14 on the door end side provided at the door end side to perform a locking operation.

When opening the window, rotate the handle in the opposite direction to the above rotation operation.
Rotating it 90 degrees and positioning it horizontally will reverse the operation described above. That is, the rising connecting rod 3
moves downward (backward), the connecting rod 5 moves to the right (backward), the falling connecting rod 8 moves upward (backward), and the lower connecting rod 10 moves rightward (backward). ), and by moving the connecting rod, the upper rod 7 and the lower rod 12
The door is pulled back to its original position, unlocking the door and allowing the window to be opened freely.

Further, the opening/closing device of the present application is constructed so that the window can be fixed at a desired opening degree by only operating the handle, and will be described below.

An opening fixing rod 19 that moves back and forth when the handle 2 is rotated by a predetermined angle (for example, 180 degrees) is disposed via a lower corner connecting member 9' made of a flexible member, etc. A regulator holding portion 16 is formed at the tip. The regulator clamping part 16 consists of clamping pieces 16a and 16b, and the opening adjuster 18, which is usually a rod such as a flexible tube, has a slidable interval, and one clamping piece 16b is a rod that fixes the opening. 19, and by rotating the handle 2, the interval between the clamping pieces narrows, and the opening adjuster 18 is clamped and fixed between the clamping pieces, that is, within the clamping part. the opening adjuster 18 at the position such that the opening position is located along the window lower part 17.
is formed into a curved shape. The opening adjuster 18 is a rod like a flexible tube that can be bent, and one end is fixed to the window frame 15, so that it slides within the adjuster holding part 16 during window opening/closing operations. When clamped and fixed by the regulator clamping part 16, the regulator from the clamped part to one end fixed to the window frame 15 has the property of holding a straight rod without bending or bending.

Effects of the invention As explained above, according to this invention, the window can be opened, closed, locked, and fixed at the desired opening by rotating the handle provided at the base of the window, that is, on the front side. There is no need to lean over and operate it like in the past. As a result, the window can be opened, closed, locked, and opened without any danger, significantly improving safety, and furthermore, it is possible to open/close the window and fix the window at the desired opening with a series of operations. Therefore, it can be said that it is excellent in usability and practicality.
