Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swing opening / closing window in which one edge of a window plate for opening / closing an opening of a window frame is hinged to the window frame, and the window plate is biased in the window opening direction. Related to the device.

2. Description of the Related Art Problems to be Solved by the Related Art and Invention In a swinging open / close window in which one edge of a window plate for opening / closing the opening of the window frame is hinged to the window frame, a method of urging the window plate in the window opening direction is disclosed. First, a telescopic stay formed by urging the rod housed in the cylinder in a projecting direction by spring elasticity or gas pressure is connected between the window frame and the edge of the window plate so that the rod protrudes. There is a method of pressing the window plate in the window opening direction by force, but since the component force in the direction perpendicular to the swing direction of the window acts on the window plate, Since the radial load acts on the hinge shaft of the hinge attached to the window frame,
As a result, the hinge has a drawback that it is liable to wear early, and the telescopic stay connected across the window plate and the window frame swings as the window plate swings in the window opening direction. As a result, the oscillating telescopic stay has a drawback that it obstructs the opening of the window.

Means for Solving the Problems As a means for solving the above problems, the present invention hinges one edge of a window plate that opens and closes an opening of the window frame, and attaches a hinged edge of the window plate. An arm is arranged along a side edge adjacent to the window plate, and an end of the arm on the hinged edge side of the window plate is pivotally supported on the window frame, and the other end is formed on the side edge of the window plate. An extendable stay formed by urging the rod housed in the cylinder in a projecting direction so that the rod is housed in the cylinder so as to be pushed, and the expandable stay is arranged along the edge of the window frame supporting the arm. While fixing the cylinder of the stay to the window frame, the other end of the connecting link whose one end is axially supported by the tip of the rod is axially coupled to the arm, and the connection is made by the projecting force of the rod protruding from the telescopic stay. The window plate is biased in the window opening direction via the link and the arm. It has a configuration.

The action and effect of the invention The oscillating opening / closing window urging device of the present invention has the above-described configuration, and since the telescopic stay is not directly connected to the window plate, the force component of the rod's protruding output in the direction along the window plate is obtained. This prevents the hinge shaft of the window plate from being subjected to a radial load, preventing the hinge from being worn quickly, and fixing the cylinder of the telescopic stay along the window frame to prevent the rod's protruding force. Since the arm is transmitted via the connecting link, the telescopic stay does not swing even if the window plate swings, and the posture staying along the window frame is maintained. Prevents corrosion by being attached to rain and exposed to rain.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 is a window frame fitted to a wall 2 of a building, and a plurality of window holes are continuously provided in a lateral direction, and each window hole has a glass plate 3 fitted therein. The plate 5 is attached to the lower edge of the window hole by a hinge so that the plate 5 can swing freely outward.
Pulleys 6 are respectively supported on both left and right sides of the upper edge of the window plate, and turning pulleys corresponding to the respective pulleys 6 of the window plate 5 are supported by brackets 7 on the upper edges of the window holes. The wire rope 8 connected to the right end of the pulley 1 is hung between the deflection pulley of the window frame 1 and the corresponding pulley 6 of the window plate 5, and is supported by the wall 2 on the left side of the window frame 1. It is turned around 10 and hangs downward, and is connected to an electric winding device 11 installed at a hand position at a lower portion of the wall 2. On one side edge of each window plate 5, an engagement roller 12 is supported at one end and arms 14 whose other end is bent at an oblique angle are arranged substantially in parallel, and the end of the bent portion is a window. A guide having a U-shaped cross-section, which is axially supported by a pin 17 at the lower end of the side surface of the vertical frame 16 of the frame 1, and the engaging roller 12 at the other end is fixed to the side edge of the window plate 5 along the side edge. It is fitted in the guide groove 20 of the member 18, and the arm 1 of the window frame 1
On the side surface of the vertical frame 16 supporting the cylinder 4, the cylinder rod of the telescopic stay 23 is formed by urging the piston rod 22 housed in the cylinder 21 in the direction of protruding from the cylinder 21 by the pressure of the high-pressure gas filling the cylinder 21. Is a vertical frame 16
The connecting pin 25 is supported by the supporting member 24 at the tip of the piston rod 22, and the roller 26 fitted to the connecting pin 25 is fixed to the vertical frame 16 below the cylinder 21. The guide member 28 is fitted in a guide groove 27 in a direction parallel to the piston rod 22, and one end of a short connecting link 30 is axially supported by a connecting pin 25 at the tip of the piston rod 22, and the other end is The pin 14 is pivotally supported by the bent portion of the arm 14 by the pin 31, and the projecting force of the piston rod 22 of the telescopic stay 23 acts on the arm 14 via the connecting link 30. The engagement roller 12 of the arm 14 is urged to swing counterclockwise about the center, and the groove surface 2 of the guide groove 20 of the guide member 18 attached to the window plate 5 By pressing a, the window plate 5 is urged in the fenestration direction.

Then, in a state where each window plate 5 is erected and closed,
When the wire rope 8 is unwound from the winding device 11, the second
In the figure, the tip of the piston rod 22 is the roller 26.
The arm 14 swings in the fenestration direction via the connecting link 30 while being guided by the guide member 28 and the guide member 28, and the arm 14 is guided by the engagement roller 12 attached to the window plate 5. Since the groove surface 20a of the guide groove 20 of the member 18 is tactilely pressed and rocked, the window plate 5 is moved to the arm 1
When the wire rope 8 is wound by the winding device 11 in this window-opening state, the window plates 5 open the arms 14. The window is closed by pulling it toward the window frame 1 against the swinging force in the window direction. In this case as well, the engagement roller 12 of the arm 14 moves while touching the groove surface 20a of the guide groove 20. Move in the guide groove 20.

In this embodiment, since each window plate 5 is biased in the window opening direction via the arm 14, the window plate is directly connected to the tip of the piston rod 22 of the telescopic stay 23 and biased. As in the case, the component force of the thrust output of the piston rod 22 in the direction along the window plate 5 does not act in the radial direction of the hinge shaft of the window plate 5.

In this embodiment, one end of the arm 14 is connected to the window frame 1
In order to allow relative movement of the other end of the arm 14 with respect to the window plate 5 due to the swing of the window plate 5 and the arm 14 caused by the fact that the pin 17 pivotally supported on the window plate 5 is not coaxial with the hinge axis of the window plate 5. , The engaging roller 12 is pivotally supported on the end of the arm 14, and the guide member 18 into which the engaging roller 12 is fitted is attached to the window plate 5 so as to be associated with the swing of the window plate 5 and the arm 14. The combining roller 12 is designed to be tactile in the guide groove 20.
When the swing centers of the arm 14 and the window plate 5 are made to coincide with each other by supporting them coaxially with the hinge shaft, the other end of the arm 14 can be fixed to the window frame 5.
