Description

[Detailed description of the invention] Industrial application field This invention consists of hinged window panels with a glass plate, etc. stretched over one side of a window frame fitted into a window hole cut through a window hole in the outer wall of a building. A projecting window that is biased by the elasticity of the body in the direction of protruding the other side to the outside and opening the window, and also closing the window against the elasticity of the spring body by pulling the wire connected to the window plate. related to switchgear.

Problems to be solved by conventional techniques and ideas Conventional projecting windows have a telescopic stay between the window frame and the window plate that houses a coil spring or sealing gas in a cylinder, and uses the elasticity of the coil spring to bias the piston rod in the direction of projecting. Because the window board was biased in the direction of opening the window by diagonally interposing it, part of the biasing force of the telescoping stay acts as a bending load on the hinge. In the window state, most of the urging force of the telescoping stay acts on the hinge, deforming or wearing it, resulting in early deterioration of sealing performance.

Means for Solving the Problems The present invention, as a means for solving the above-mentioned problems, includes a first arm in which a window board is hinged to one side of the window frame, and one end of which is pivotally supported on the window frame. The end portion is pivoted to the middle portion of a second arm whose one end portion is connected to the window plate, and a flexible strip for fenestration connected to the other end portion of the second arm is connected to the second arm of the first arm. the other end of the second arm is moved so as to widen the angle formed by the second arm, and a spring body is attached to the window frame that applies a fenestration force by pulling the flexible strip for fenestration, and when the window is closed, A space is provided between the support shaft supporting the other end of the first arm and the flexible strip for fenestration in a direction perpendicular to the pulling direction of the flexible strip for fenestration, and the flexible strip is stretched in the direction of closing the window. The window closing wire is connected to the window plate.

Functions and Effects of the Invention The present invention has the above structure, and the flexible strip for fenestration is pulled by the elasticity of the spring body, so that the second
Since the arm swings about the intermediate point supported by the first arm as a fulcrum and acts to push the window panel outdoors, the large force acting on the rotating shaft due to the tensile force of the flexible fenestration strip The part acts on the support shafts at both ends of the first arm, and the load acting on the hinge is extremely small. Therefore, even if a hinge with a small shaft diameter is used, deformation and wear are small, and durability is high. It has excellent effects.

Embodiment Hereinafter, a first embodiment of the present invention will be described based on FIG.

In the figure, reference numeral 1 denotes a window frame fitted into a window hole cut through the outer wall of a building, and a window plate 3 with a glass plate 4 stretched through a hinge 2 provided on the inner surface of its upper edge.
is suspended and supported so that it can freely swing in the direction of opening the window by protruding toward the outdoors, and near the lower end of both side edges of this window board 3, a second arm 5 has its lower end attached to a shaft 6. The lower end of the first arm 7 is supported by a shaft 8 near the lower end of the inner surface on both sides of the window frame 1, and the upper end of the first arm 7 is supported by a shaft 9. A compression coil spring 11 is fitted into a vertically elongated holding cylinder 10 connected to an intermediate point near the upper end of the arm 5 and fixed at a position near the indoor side of the inner surface of both side edges of the window frame 1.
A fenestration wire 13 connected to a terminal fitting 12 abutting the upper end passes through the hollow of the compression coil spring 11 and protrudes from the lower surface of the holding cylinder 10, and a turning roller is pivotally supported by the window frame 1 below the fenestration wire 13. A terminal fitting 15 is connected to the upper end of the second arm 5, and two window panels are connected to the lower end surface of the window panel 3 at intervals in the width direction. The side pulley 16 is pivotally supported, and two brackets 19 are freely swingably supported by a shaft 20 at an interval in the width direction at the lower edge of the window frame 1.
A window frame side pulley 17 is pivotally supported on the window frame 1, and a window closing wire 18 is unwound from a winding drum (not shown) disposed at the lower part of the room, rises along the wall surface, and runs along the lower edge of the window frame 1. After being horizontally routed,
One window frame side pulley 17 is turned, the wire is hooked onto the corresponding window plate side pulley 16, the cable is routed along the lower edge of the window plate 4, the other window plate side pulley 16 is turned, and the other window plate side pulley 16 is turned. The pulley 17 on the window frame side is turned to be similarly routed to adjacent windows, and its terminal end is fixed to the wall.

Next, to explain the operation of this embodiment, since the fenestration wire 13 is constantly pulled by the elastic expansion force of the compression coil spring 11, the second arm 5 connected to one end thereof is connected to the first arm 7. A rotating force is applied in the clockwise direction in the figure using the shaft 9 at the upper end as a fulcrum, and the urging force causes the window plate 3 to be opened to the outside as shown by the solid line in the figure. When the winding drum (not shown) is rotated and the window closing wire 18 is pulled, the window plate 3 rotates around the hinge 2 so as to be drawn toward the indoor side, and at this time, the second arm 5 and the first arm 7 gradually assumes an upright position, and as shown by the chain line in the figure, the window plate 3 hits the gasket 21 of the window frame 1, resulting in a closed window position.
At this time, the compression coil spring 11 is connected to the fenestration wire 1
When the window closing coil 18 is unwound by reversing the winding drum (not shown), the window plate 3 is elastically contracted by the tensile force of the compression coil spring 11. The windows are pushed out to the outside and opened.

In the first embodiment, the fenestration wire 13 connected to the second arm 5 may be connected to the upper end of a tension coil spring whose lower end is connected to the window frame 1, and pulled downward.

Next, a second embodiment of the present invention will be described based on FIGS. 2 and 3. On both sides of the window frame 1,
Each of them is equipped with a biasing unit 30 for biasing the window plate 3 in the window opening direction. A female threaded body 3 is fixed to a lower end portion of a vertically elongated holding cylinder 35 to a male threaded cylinder 33 of a supporting body 31 which is fixed and protruded.
7, and also attach the first arm 4 to the support body 31.
The lower end of 7 is supported by a shaft 48, the second arm 45 is supported by a support shaft 49 at the upper end thereof, and one end is attached to the terminal fitting 38 which is in contact with the upper end of the compression coil spring 36 fitted into the holding cylinder 35. The bonded fenestration wire 13 is passed downward through the hollow of the compression coil spring 36 and penetrated through the center hole 34 of the male threaded cylinder 33.
It has a structure in which the turning roller 32 is bent upward and the other end is connected to one end of the second arm 45, and the support body 31 is fixed to the window frame 1, and the second arm 45 is The other end is the shaft 46
The second arm 45 is connected to the first arm 4 by its support shaft 49.
An engagement guide portion 50 is formed by expanding the portion supported by the upper end of the window into an arc shape. The alignment guide portion 50 protrudes toward the biasing unit 30 side, and is provided between the fenestration wire 13 and the support shaft 49, which are routed around the guide groove 51 on the outer periphery, and the direction in which the fenestration wire 13 is pulled. They are spaced at right angles.

When opening the window from the closed state, when the window closing wire 18 is let out from the winding drum, the stretched window opening wire 13 connects to the shaft 49, which is the fulcrum of rotation of the second arm 45. Since the second arm 45 is spaced in the direction perpendicular to the tension direction,
The moment of rotation is large, and therefore the window plate 3 quickly swings in the window opening direction even immediately after opening the window. In addition, when the biasing unit 30 rotates the holding cylinder 35 with respect to the support body 31 and screws it in the vertical direction along the male threaded cylinder 33, the position of the terminal fitting 38 that contacts the upper end of the compression coil spring 36 changes. The compression coil spring 36
Since the female threaded body 37, which the lower end of the fenestration contacts, moves up and down together with the holding tube 35, the magnitude of the elastic expansion force of the compression coil spring 36 changes, and the tensile force of the fenestration wire changes. The biasing force in the direction can be adjusted.

FIG. 4 shows a biasing unit 30a as a modification of the biasing unit 30, which includes a support 31a.
Instead of mounting the holding cylinder 35a by screwing, the holding cylinder 35a is fitted so that it can slide freely in the vertical direction, and the holding cylinder 35a is held in a raised state while elastically contracting the compression coil spring inside the holding cylinder 35a, and is supported. A spacer 4 having a C-shaped cross section is provided between the flange 31b formed on the body 31a and the step 35b formed on the lower end surface of the holding cylinder 35a.
This biasing unit 30a can adjust the biasing force in the fenestration direction by changing the amount of elasticity of the compression coil spring using spacers 40 of different lengths. can.

5 to 7 show a third embodiment of the present invention, in which the second
One urging unit 30 having the same structure as the embodiment
The support body 31 is fixed, and one end of the second arm 45 is attached to a connecting member 44 that is slidably and rotatably fitted into a circular guide rod 43 attached along the lower edge of the window panel 3. The second arm 45 is pivotally supported, and when opening the window, one end of the second arm 45 is attached to the connecting member 44.
While moving along the guide rod 43 through the window plate 3, both arms 45 and 47 swing in a substantially horizontal plane, and the window plate 3 is projected.
By simply attaching one biasing unit 30, the window can be opened and closed while maintaining the left and right balance, so when two biasing units 30 are attached to both sides of the window as in the second embodiment, It has the advantage of being able to be manufactured at a lower cost than.

Note that the present invention is not limited to a projecting window in which the window panel 3 is supported on the upper edge of the window frame 1 and the lower edge thereof is protruded to open the window as explained in each of the above embodiments. Other types of windows that are opened by supporting the board 3 on the lower edge of the window frame 1 and protruding the upper edge side, or by supporting it on one side edge and protruding the other side edge side. It can also be applied to

Note that the fenestration wire 13 can be replaced with a flexible wire such as a chain.
