Description

[Detailed description of the invention] Industrial application field The present invention relates to a swing opening/closing window in which the window plate opens and closes by swinging around one edge supported on the window frame as a fulcrum, and in particular, the invention relates to a swing opening/closing window in which the window plate opens and closes by swinging around one edge supported on the window frame. This invention relates to a switchgear that can be reliably locked.

Problems to be solved by conventional techniques and ideas In general, a swinging window has a window plate pivoted on one side of a window frame fitted into a window hole, and a window plate is supported along at least one of the two sides on both sides of that side. An actuating piece that slides along a guide formed by the window plate is connected by a link, and the sliding of the actuating piece swings the window plate to open and close it, but when the window is closed, It is necessary to install a locking device to prevent the window from opening due to wind pressure or force from outside, and for this reason, conventionally,
A device was used in which a hook protruding from the window plate engaged with a movable claw of a closing device attached to the window frame to lock the window when the window was closed. Not only do these latching pieces and closing devices have to be released, making the fenestration operation troublesome, but they also need to be attached to the swinging edge of the window panel and the corresponding side of the window frame. It had a defect that sometimes became exposed and became an eyesore.

Means for Solving the Problems The present invention aims to solve the above drawbacks by sliding along a guide by a motor or manual drive, and by releasing the drive, it can be moved to any position. The drive piece held by the actuating piece corresponds to the actuating piece through a spring body in the window closing direction and directly in both window opening directions, and has a hook part at one end and a hook part at the other end, respectively. The formed closing rod is supported to freely slide along the guide and biased in the direction of unlocking, and when the window plate is closed, the protrusion projecting on the drive piece engages with the latching portion of the closing rod. By operating the closing rod while the driving piece elastically contracts the spring body, the protrusion formed on the window plate is engaged with the hook of the closing rod, thereby locking the window so that it cannot be opened.

Functions and Effects of the Invention The present invention has the above-mentioned configuration, and the drive piece that operates the window plate in the window closing direction via the actuating piece and the link is further driven excessively in the window closing direction after the window has been closed. Since the window is designed to lock, no special operation is required for locking, and the window can be automatically locked when the window is closed. At the same time, when the window is opened, when the drive piece is moved in the direction of opening the window, the operating piece is moved. While the window is held in the closed position by the elasticity of the spring body, the closing rod operates in the direction of unlocking due to the biasing force.
The hook part comes off the protrusion of the window plate and the window can be opened, and then the driver pushes the operating body in the direction of opening the window, and the window plate swings in the direction of opening the window via the link,
There is no need to perform a special unlocking operation prior to window opening, and the lock is automatically released by the window opening movement, either manually or by motor, so opening and closing operations are extremely simple, and the locking of the closing rods, etc. Since the mechanism is attached along the side of the window frame where the link is attached, it does not become an eyesore when the window is opened.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings.

The swinging opening/closing window of this embodiment has a window plate 3 attached to an upper frame 2a of a window frame 2 fitted into a window hole 1 made transparent in the wall of a building.
is supported by hinges 4 to freely swing toward the outdoors, and brackets 25, 25 fixed to the lower ends of both vertical frames 3b, 3b of window board 3, and left and right vertical frames 2b, 2b of window frame 2. Guide pipes 6, 6 installed along
The actuating bodies 7, 7, which are fitted in the shafts 7a and 7a to freely move up and down, are attached to both ends of the pair of link stays 8, 8, respectively.
They are connected to each other by being supported by 25a, and as the actuating bodies 7, 7 descend, the window plate 3 swings in the window opening direction, and as it rises, the window plate 3
is designed to swing in the window closing direction.

The guide tube 6 attached to each vertical frame 2a has a fourth
As shown in the figure, the cross-sectional shape of the inner circumference is an elongated ellipse with circular parts 6a, 6a on both sides of the flat part 6b, and a longitudinal guide groove is formed in the flat part 6b from hollow to the outside. 10, in which a pair of engaging portions 9, 9, which are vertically spaced apart from each other on the actuating body 7, penetrate through the guide groove 10 from the outside and are fitted into the flat portion 6b. , projections 9 formed on both sides of the insertion end in a direction perpendicular to the removal direction.
a, 9a between the side edge of the guide groove 10 and the circular part 6a, the actuating body 7 is fitted in such a way that it cannot be removed and can be moved up and down freely. Cylindrical portions 15 that align with the circular portion 6a are provided on both sides of the main body portion 15a that align with the portion 6b and the guide groove 10.
The drive body 15 formed by the elements b and 15b is fitted between the engaging portions 9 and 9 of the actuating body 7 from above and below so that it cannot be removed and can freely slide. A compression coil spring 16 is fitted in an elastically compressed state between the upper end surface of the main body 15a of the drive body 15 and the upper engaging portion 9, and the guide tubes 6 on both sides are connected from the lower frame 2c of the window frame 2. The upper ends of the pair of geared cables 14, 14, which are routed with the inside facing upward, are respectively
The gear 32 is rotated by operating the handle 31 of the operation box 30, which is connected to one cylindrical portion 15b of the drive body 15 and attached to the center position of the lower frame 2c of the window frame 2, and both geared cables 14,
14 in the wiring direction, the driving body 15 and the actuating body 7 on both sides of the window are pressed against the lower engaging portion 9 by the elastic expansion force of the compression coil spring 16. It is designed to move up and down as one unit.

The driver 15 also includes a guide groove 10 of the guide tube 6.
A locking pin 17 is formed to protrude from the guide tube 6, and a vertically long closing rod 19, which has a corresponding locking portion 18 formed above the locking pin 17 at its upper end, can be freely moved up and down. , and is normally fitted in a state in which it is in contact with a stopper 21 formed at the lower end of the guide tube 6 due to its own weight, and an upwardly directed hook portion 27 is attached to the lower end of the closing rod 19. It is formed so as to correspond to the lower part of the closing pin 26 which projects from the bracket 25 of the window plate 3 in the window state.

Next, to explain the operation of this embodiment, when closing a window from an open state, when the handle 31 is operated to drive the driver 15 in the upward direction via the geared cable 14, the compression coil spring 16
As the actuating body 7 unites with the driving body 15 and moves up along the guide tube 6 due to the elastic expansion force, the protruding window plate 3 swings in the direction of closing the window, and the window is closed. After this, when the handle 31 is continued to be operated, the lower end of the window plate 3 comes into contact with the gasket 28 fixed to the window frame 2, and the link stay 8 assumes an almost vertical posture, so that the actuating body 7 does not rise. However, the driving body 15 moves upward away from the lower engaging part 9 while elastically compressing the compression coil spring 16 between it and the upper engaging part 9, and the latching pin 17 of the driving body 15 moves up.
The closing rod 19 is moved upward by being hooked to the hooking part 18 of the closing rod 19, and as the closing rod 19 moves upward, the hook portion 27 at the lower end of the closing rod 19 is attached to the closing pin 26 of the window plate 3 on the lower side. When the handle 31 is stopped in this state, a non-illustrated non-illustrated button in the operation box 30 is engaged with the handle 31, making it impossible to swing the window plate 3 in the window opening direction and locking the window in the closed state. Since the rotation of the gear 32 is restricted by the reversible clutch and the movement of the geared cable 14 is stopped, the locked state is maintained.

Furthermore, when opening the window from the closed state, if the handle 31 is operated in the opposite direction from when the window is closed, the operating body 7 remains stopped due to the elastic expansion force of the compression coil spring 16 immediately after the operation starts. When the drive body 15 moves downward, the closing rod 19 descends under its own weight, and the hook portion 27 comes off from the closing pin 26 of the window plate 3, releasing the lock. When the driver 15 is operated, the driver 15 comes into contact with the lower engaging portion 9, so that the driver 7 is pushed down and moves downward together with the driver 15, and the window plate 3 is pushed out and opened. It is windowed.

Note that instead of moving the closing rod 19 downward to the unlocking position by its own weight, it may be biased in the unlocking direction by the elasticity of a spring.

In this embodiment, the geared cable 14 is used to drive the drive body 15 up and down, but the means for moving the drive body 15 up and down is not limited to this. It can be raised and lowered by taking out and feeding out, or the driving body 15
It may also be possible to raise and lower the screw by connecting it to a female threaded body screwed onto a threaded rod and causing the female screw body to advance as the threaded rod rotates.

The present invention is based on the window plate 3 as explained in the above embodiment.
The invention is applicable not only to windows in which the window plate 3 is supported to the upper frame 2a of the window frame 2, but also to other types of swinging opening/closing windows in which the window board 3 is supported to the lower frame 2c or side frame 2b of the window frame 2. It is something that can be done.
