[Detailed description of the invention]

INDUSTRIAL APPLICATION FIELD The present invention relates to a slider provided at the upper end of a window plate that engages with a vertical sliding guide provided on a window frame, and an upper end of an arm whose lower end is pivoted to the window frame. For example, in a sliding window in which the upper end of the window board descends along a sliding guide and the arm tilts, the lower end is pushed up to open the window. This invention relates to a balancing device that is used to manually open a window plate and stop and hold it at an arbitrary opening angle for use in entering and exiting a window. Prior Art and Problems to be Solved by the Invention Conventionally, this type of sliding window balancing device has been designed to pull the upper end of the window panel downward in order to balance the weight of the window panel. Tension coil springs and weights connected together are known, but in the case of tension coil springs, as the fenestration angle of the window plate increases, the tension coil spring contracts and the tension weakens. Even in the case of Regardless, if you try to stop the window board at an arbitrary opening angle, it is necessary to increase the frictional force between the slider at the upper end of the window board and the sliding guide, which requires a large amount of force to open and close the window board. There were some drawbacks that required it. 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. Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 1 to 3, reference numeral 1 is a sliding window, in which a window plate 3 is fitted inside a window frame 2, and sliders 4 provided on both sides of the upper end of the window plate 3 move the window frame. The lower end of the arm 6 is supported by a shaft 7 on the side edge of the window frame 2. The upper end is supported by a shaft 8 on the side edge of the window plate 2, and as the slider 4 of the window plate 3 descends along the sliding guide 5 and the arm 6 tilts,
The lower end of the window plate 3 is pushed up to open the window. A first wire 10 is attached to the slider 4 provided on the window frame 3.
One end of the first wire 10 is connected, and the other end of the first wire 10 is routed downward along the side edge of the window frame 2.
A shaft 8 is connected to the lower end of the first tension coil spring 13 by turning the pulleys 11 and 12 which are pivotally supported at the lower end, and supports the upper end of the arm 6.
One end of the second wire 15 is connected to the second wire 15.
The other end of the wire 15 is connected to the upper end of the first tension coil spring 13 by turning pulleys 16 and 17 that are pivotally supported at the approximate center and upper end of the window frame 2, and further, One end of a third wire 19 is connected to the upper end of the first tension coil spring 13, and the other end of the third wire 19 turns a pulley 20 pivotally supported on the upper end of the window frame 2. First tension coil spring 1
The lower end of the second tension coil spring 22 is fixed to the window frame 2, and these members are arranged on both the left and right sides of the sliding window 1. It is set up. This 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 connected to the first wire 10.
By being pulled by the spring force of the tension coil spring 13, a fenestration force is applied to the window plate 3, and at the same time, the second wire 15 connected to the shaft 8 fixed to the window plate 3 is also By being pulled by the tension coil spring 13, a window closing force is applied to the window plate 3, and by providing this second wire 15,
Application of an unnecessarily large opening force to the window plate 3 is suppressed, and at the same time, when the window plate 3 is opened, the amount of contraction of the first tension coil spring 13 is suppressed.
This suppresses a decrease in the spring force of the tension coil spring 13, and when opening the window plate 3, the first wire 1
As the fenestration angle increases, the first tension coil spring 13 contracts little by little and gradually moves upward while simultaneously receiving the fenestration force of 0 and the fenestration closing force of the second wire 15. Here, assuming that the second tension coil spring 22 does not exist, the tension acting on the first wire 10 and the second wire 15 during the opening process of the window plate 3
Although F ₁ and F ₂ are equal, the moment in the window closing direction that acts on the window plate ₃ due to the tension F 1 of the first wire 10 increases as the fenestration angle of the window plate 3 increases.
As the distance between the first wire 10 and the shaft 8, which is the length of the arm, increases, the moment increases;
The moment in the window closing direction that acts on the window plate 3 due to the tension F ₂ of the wire 15 is reversed because the larger the fenestration angle, the smaller the distance between the second wire 15 and the slider 4, which is the length of the arm. Therefore, as the window approaches the fully closed state, the window closing force becomes stronger than the window opening force and the window pane 3 always tries to close the window, and conversely, as it approaches the fully open state, the window opening force decreases. The window plate 3 constantly attempts to open the window due to the force of the window, resulting in loss of balance. However, in this example,
The third wire 1 is attached to the upper end of the first tension coil spring 13.
9 is connected to the upper end of the second tension coil spring 22, the second wire 1
The resultant force of the tension F ₂ of 5 and the tension F ₃ of the third wire 19 is
This will balance the tension F ₁ of the first wire 10,
As the opening angle of the window plate 3 gradually increases and the first tension coil spring 13 moves upward, the second tension coil spring 13 moves upward.
The tension coil spring 22 contracts and its spring force becomes smaller, and as a result, as the fenestration angle of the window plate 3 increases, the tension F ₃ of the third wire 19 gradually becomes smaller. The tension F ₂ of the second wire 15 increases, and therefore, the moment acting on the window plate 3 in the window closing direction increases the fenestration angle when the second tension coil spring 22 is not provided. Accordingly, the gradually decreasing value is corrected and averaged, and the difference with the moment in the window opening direction acting on the window plate 3 becomes smaller, so that a balance can be achieved. Next, regarding the balancing ability of this example, the fourth
This will be explained based on the diagram and FIG. First, as shown in FIG. 4, when the window plate 3 is opened at an opening angle of θ ₁ °, the force of pulling down the slider 4 due to the tension of the first wire 10 is FKg, and the dead weight of the window is GKg. The force with which arm 6 pushes window plate 3 is NKg,
The force applied to the window plate 3 in the direction perpendicular to the arm 6 due to the tension of the second wire 15 is PKg, the force acting on the lower end of the window plate 3 is WKg, and the distance from the slider 4 of the window plate 3 to the shaft 8 is PKg. The length of arm 6 is l ₁ mm, the length of arm 6 is l ₂ mm,
If the length from the slider 4 to the center of the window plate 3 is l ₃ mm, and the angle between the first wire 10 and the arm 6 is θ ₂ °, then from the moment balance equation, Gl ₃ sinθ ₁ −Nl ₁ sin (θ ₁ + θ ₂ ) + Pl ₁ sin (θ ₁
+θ ₂ −90)+2Wl ₃ =0…… Also, from the force balance equation, G+F+Wsinθ ₁ −Ncosθ ₂ −Psinθ ₂ =0 is obtained. In addition, the force FKg for pulling down the slider 4 is:
The initial tension of the first tension coil spring 13 is R ₁ Kg, the spring constant is K ₁ Kg/mm, and the first tension coil spring 1
Assuming that the displacement amounts of the window plate 3 at the lower and upper ends of No. 3 from the fully closed state are S ₁ mm and S ₂ mm, one first tension coil spring 13 is installed on each side of the window. Therefore, it is expressed as F=F ₁ ×2={R ₁ −K ₁ (S ₁ −S ₂ )}×2 ...... Also, the force applied perpendicularly to the axis 8 of the window plate 3 is PKg
From FIG. 5, P=(F ₂ l ₂ sinθ ₃ /l ₂ )×2=F ₂ sinθ ₃ ×2 where F ₂ =F ₁ −F ₃ and the second tension coil spring The initial tension of 22 is R ₂ Kg, the spring constant is K ₂
Assuming Kg/mm, since F ₃ =R ₂ −K ₂ S ₂ , it is expressed as P=(F ₁ −R ₂ +K ₂ S ₂ )sinθ ₃ ×2 . Further _, the amount of displacement of the lower end of the first tension _coil spring 13, that is, the amount _of descent _{S 1} mm of _the slider 4 is calculated from _FIG . ₂ ...... Also, the amount of displacement of the upper end of the first tension coil spring 13, that is, the axis 8 of the upper end of the arm 6
As shown in Fig. 5, the feeding amount S ₂ mm is determined by the vertical distance between the shaft 8 and the pulley 16 being Amm and the horizontal distance being Bmm when the window plate 3 is in the fully closed state. Then, It is expressed as And l ₁ = 394mm, l ₂ = 950mm, l ₃ = 752.5mm,
G = 75Kg, R ₁ = 50Kg, K ₁ = 0.091Kg/mm, R ₂ =
37.5Kg, K ₂ =0.1195Kg/mm, A=120mm, B=50
mm, and when the fenestration angle θ ₁ ° is increased by 10° from the fully open state of the window board 3, the force WKg that acts on the tip of the window board 3, and the force FKg that pulls down the slider 4 with the first wire 10. , the force NKg of the arm 6 pushing the window plate 3, the displacement S ₁ mm of the slider 4, and the displacement S ₂ mm of the shaft 8 at the upper end of the arm 6 were calculated based on the above formulas. The results shown in the following table were obtained.

[Table] Here, if the force W acting on the tip of the window plate 3 is 0, the window opening force and the window closing force applied to the window plate 3 are balanced, and the window plate 3 can be moved without applying any external force. According to the present example, from the above table, W is in the range of -2.51Kg to 7.19Kg, and takes a small value close to 0, and in the entire fenestration area. It has been proven that the balance is almost balanced. Structure and effects of the invention As specifically explained in the above embodiments,
The sliding window hanging device of the present invention engages a slider provided at the upper end of the window plate with a vertical sliding guide provided on the window frame, and an arm whose lower end is pivoted to the window frame. In a sliding window, the upper end of which is pivoted to a window plate, and the upper end of the window plate descends along the sliding guide and the arm tilts to push up the lower end and 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 other end of the first tension coil spring is connected to a wire that pulls the window plate in the window closing direction. , one end of which 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 applies fenestration force to the window plate. 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 window-closing force relatively increase as the window-closing force increases,
Over the entire fenestration area of the window pane, the difference between the opening force and the closing force becomes small and almost balanced, so that when stopping the window pane at any fenestration angle, Since only a small frictional force is required between the slider and the sliding guide, the window panel can be opened and closed easily.
