Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to a method in which a slider provided at the upper end of a window plate is engaged with a vertical sliding guide provided in a window frame. The upper end of the arm which is pivoted on the arm is pivoted on the window plate, and the upper end of the window plate is lowered along the sliding guide and the arm is tilted, so that the upper end of the window is pushed out. The present invention relates to a balancing device used to manually open the window plate of a sliding window designed to be an rjFJ window, for example, for firefighter access, and to stop and hold the window plate at an arbitrary opening angle.

17 Problems to be Solved by the Prior Art and the Invention Conventionally, this type of sliding window balancing device has been designed to balance the weight of the window panel by attaching one end of the j to the upper end of the window panel downward. Tension coil springs that connect tension coil springs and weights are known, but in the case of tension coil springs, as the fenestration angle of the window plate increases, the tension coil springs contract and the tension becomes weaker. Also in the case of

Since the moment in the fenestration direction increases as the fenestration angle increases, it is impossible in any case to balance over the entire fenestration area, and nevertheless If you try to stop it at an angle, you need to increase the frictional force between the slider at the top of the window board and the sliding guide.

There was a drawback that a large amount of force was required to open and close the window panels.

The present invention has been completed in view of the above points, and is capable of stopping a window board at an arbitrary fenestration angle without creating a large frictional force between the slider of the window board and the sliding guide. To provide a device for suspending sliding windows that enables the following.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings.

In FIGS. 1 to 3, 1 is a sliding window,
A window board 3 is fitted inside the window frame 2, and sliders 4 provided on both sides of the upper end of the window board 3 slide on vertical sliding guides 5 formed on both side edges of the window frame 2. The lower end of the arm 6 is supported by a shaft 7 on the side edge of the window frame 2, and the upper end of this arm 6 is supported on the side edge of the window plate 2 by a shaft 8. As the slider 4 of the window plate 3 descends along the sliding guide 5, the arm 6 tilts.

The lower end of the window plate 3 is pushed up to open the window.

One end of a first wire 10 is connected to a slider 4 provided on the window frame 3, and the other end of the first wire 1o is routed downward along the side edge of the window frame 2, and the slider 4 is connected to the slider 4 provided on the window frame 3. One end of the second wire 15 is connected to the shaft 8, which is connected to the lower end of the first tension coil spring 13 by rotating the pulley 1L12, which is pivotally supported at the lower end of the arm 6. The other end of the second wire 15 is connected to the upper end of the first tension coil spring 13 by turning pulleys 16 and 17 which are pivotally supported at the approximate center and upper end of the window frame 2. It is connected.

Furthermore, a third
One end of the wire 19 is connected, and the other end of the third wire 19 rotates a pulley 20 pivotally supported at the upper end of the window frame 2.
It is connected to the upper end of a second tension coil spring 22 arranged in parallel with the first tension coil spring 13 , and the lower end of the second tension coil spring 22 is fixed to the window frame 2 . are placed on both the left and right sides of the

The present embodiment has the above structure, and the first wire 10 connected to the slider 4 at the upper end of the window plate 3 is pulled by the deflection force of the first tension coil spring 13, so that the window plate 3 At the same time, the second wire 15 connected to the shaft 8 fixed to the window plate 3 is also pulled by the first tension coil spring 13, so that a window closing force is applied to the window plate 3. By providing this second wire 15,
This prevents excessive fenestration force from being applied to the window plate 3.

At the same time, the amount of contraction of the first tension coil spring 13 when the window plate 3 is opened is suppressed, and the first tension coil spring 1
Therefore, when opening the window plate 3, the fenestration force due to the first wire 10 and the second wire 1 are reduced.
As the window opening angle increases, the first tension coil spring 13 contracts little by little and gradually moves upward while simultaneously receiving the window closing force of 5.

Here, assuming that the second tension coil spring 22 does not exist, the first wire 10
Although the tensions F1 and F2 acting on the second wire 15 are equal, the moment in the window closing direction that acts on the window plate 3 due to the tension F1 of the first wire 10 increases as the opening angle of the window plate 3 increases. The moment increases as the distance between the first wire IO, which is the length of the arm, and the shaft 8 increases, and on the other hand, the moment in the window closing direction that acts on the window plate 3 due to the tension F2 of the second wire 15 is determined by the fenestration angle. The larger the distance, the smaller the distance between the second wire 15 and the slider 4, which is the length of the arm, and the smaller the moment. Therefore, the closer the window is to the fully open state, the closer the window closing force becomes to the window opening force. In contrast, the closer the window is to the fully open state, the more the window opening force becomes superior to the closing force, and the window plate 3 always tries to open the window, resulting in an imbalance. However, in this embodiment, the first
Since one end of the third wire 19 was connected to the upper end of the tension coil spring 13 and the other end was connected to the upper end of the second tension coil spring 22, the tension F2 of the second wire 15 and the tension FJ of the third wire 19 The resultant force is the tension F of the first wire 10,
As the fenestration angle of the window plate 3 gradually increases and the first tension coil spring 13 moves upward, the second tension coil spring 22 contracts and its spring force becomes smaller. As the opening angle of the window plate 3 increases, the tension Fj of the third wire 19 gradually decreases, and the tension F2 of the second wire 15 increases accordingly. The moment in the window direction, which would gradually decrease as the fenestration angle increases when the second tension coil spring 22 described above is not provided, is corrected and averaged, and the moment in the fenestration direction acting on the window plate 3 is corrected and averaged. The difference with the moment becomes smaller and balance is achieved.

Next, the balancing ability of this embodiment will be explained based on FIGS. 4 and 6.

First, as shown in FIG. 4, when the window plate 3 is opened at an opening angle of 016, the force of pulling down the slider 4 due to the tension of the first wire 10 is F kg, and the dead weight of the window is G kg.

Further, the force Fkg for pulling down the slider 4 is determined by Rlkg being the initial tension of the first tension coil spring 13 and KI being the spring constant.
kg/ll1ll, and the amount of displacement of the lower end and upper end of the first tension coil spring 13 from the fully open state of the window plate 3 is S(

Structure and Effects of the Invention As specifically explained in the above embodiments, the sliding window hanging device of the present invention has a slider provided at the upper end of the window plate and a vertical slider provided on the window frame. The upper end of the arm that is engaged with the sliding guide and whose lower end is pivoted to the window frame is pivoted to the window plate, and the arm is tilted while the upper end of the window plate descends along the sliding guide. In a sliding window whose lower end is pushed up to open the window, one end of the first tension coil spring is connected to a wire that pulls the upper end of the window plate downward, and the first tension coil a wire that extends the other end of the spring to pull the window plate in the direction of closing the window;
The gist is that one end is connected to the other end of a second tension coil spring connected to the window frame, and the wire connected to one end of the first tension coil spring is used to temporarily apply fenestration force to the window. A wire connected to the other end applies a closing force to the window plate, and a second tension coil spring is connected to the other end of the first tension coil spring to adjust the fenestration angle of the window plate. By making the tension of the wire that applies the fenestration force relatively larger as the size increases, the difference between the fenestration force and the fenestration force (decreasing and almost Balance can be maintained, and therefore, when stopping the window plate at a desired opening angle, the frictional force required between the slider and the sliding guide is small, making it easier to open and close the window plate. It produces effects that are easy to perform.
