Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention is designed to move an actuating member mounted on a frame parallel to a pivot of a shoji screen in alternate directions along the length of the frame so as to project the actuating member. The present invention relates to a locking device for a pivoting window, in which a door is locked to a closed state by engaging with a hooking portion of a window frame, and the lock is released by removing a protrusion from the hooking portion.

Problems to be Solved by the Conventional Technology and Invention A horizontal axis that supports a shoji freely around a horizontal axis passing between the upper and lower frames of the window frame is parallel to the rotating axis of the shoji of the rotating window. The operating member with the projection formed on the lower frame is mounted so that it can slide freely in the length direction of the lower frame, and the operating member slides in alternate directions.
A locking device that locks the shoji in a window-closing position by engaging the protrusion with a retaining portion formed on the lower frame of the window frame and releasing the lock by removing the protrusion from the retaining portion. As for the one in which the actuating member is slid by electric drive, conventionally, the electric motor is fixed to the indoor side surface of the lower frame of the shoji and the tip of the drive piece connected to the output shaft is used as the actuating member. The actuating member is slid by engaging and driving the electric motor by operating a control device that is connected to a commercial AC power supply and fixed to an indoor wall surface to swing the driving piece. However, this lock device not only spoils the aesthetics of the vehicle because the electric motor and the driving piece protruded from the lower frame to the indoor side, but it also hits the obstacles when people move by the window. There is Furthermore, a lead wire for connecting the electric motor to the control device is guided to the window frame near the pivot of the shoji, along the lower frame to which the electric motor of the shoji is fixed and the vertical frame perpendicular to the lower frame. Along the vertical frame, from the corners of the window frame to the inside of the wall toward the control device, because it was designed to be wired in a long and complicated route, there is a drawback that the wiring work takes time, These are a vertical axis rotation window with the vertical axis passing between the left and right vertical frames as the center of rotation, a projecting window with the upper frame as the center of swing, a tilting window with the lower frame as the center of swing, and one of the vertical windows. The same problem occurs when it is applied to other types of rotating windows such as a door type swinging window having a frame as a swing center.

Means for Solving the Problems The present invention, as a means for solving the above problems, supports a screw rod on an elongated base body only for rotation only and fixes an electric motor to connect the screw rod to the screw rod. A drive unit, which is formed by screwing a female screw body with a connecting portion formed on the outer periphery of a screw rod so as to be non-rotatable around the axis, is fixed to the window frame and used as an actuating member for the shoji screen and a connecting part in the window closing posture of the shoji screen. The structure is such that an engaging portion for fitting is provided.

Advantageous Effects and Advantages of the Invention The present invention has the above-described structure, and in the state where the shoji has a closed window posture and the engaging portion of the operating member is fitted into the connecting portion of the female screw body, the screw rod is rotated by driving the electric motor. As the female screw body whose rotation around the axis is restricted is screwed in one direction along the threaded rod, the operating member slides in the same direction due to the engagement of the engaging portion with the connecting portion. Then, the projection engages with the hooking part to lock the shoji into a closed window state.In addition, when the electric motor is driven to rotate the screw rod in the reverse direction in the locked state, the sliding movement of the female screw body is caused. Then, the operating member slides in the direction in which the projection is removed from the hook portion to release the lock, and the drive mechanism such as the electric motor is integrally fixed as the drive unit. It is easy to fix the base with screws. Since the electric motor for sliding the actuating member is fixed to the window frame side, the lead wire is arranged along one frame to which the electric motor of the window frame is fixed, or Further, the electric motor can be connected to the control device by guiding it from the corner portion of the window frame along the other frame perpendicular to the frame to the control device. The wiring route of the lead wire is shorter and the wiring work can be performed in a shorter time compared to the case where the electric motor is fixed to the end of the base body. By sticking along the direction, it can be concealed inside the window frame by making it elongated shape, so it is possible to expose it to the outside and spoil the aesthetics or stick it out indoors. Sometimes it gets in the way of people's movements There is an effect that can be mounted without.

The operating arm 16 thus formed is oscillated in a direction opposite to that of the drive shaft 12 about the drive shaft 12, and the oscillating end 16 is oscillated in one direction or in the opposite direction. While the sliding door 17 moves a short distance along the guide rails 18 formed on the left and right vertical frames 4b and 4b of the shoji screen 4, the shoji screen 4 rotates in the window opening direction or the window closing direction. , When the driving of the opening / closing electric motor 7 is stopped at any opening, the external gear 14 and the internal gear 1
The swinging arm 16 is prevented from swinging by meshing with the swing arm 5, and the shoji 4 is held in a constant inclined posture.

The shoji 4 includes upper and lower frames 4a and 4c and left and right frames 4a and 4c.
b and 4b, slidable guides 21 are slidably fitted in the slide guides 21 respectively, and the lengths of the adjacent end portions of the respective actuating plates 22 that are adjacent to each other at right angles to each other. Connected by a strip-shaped spring plate 23 that can be bent with a large curvature at any part of the direction, so that the four operating plates 22 move integrally along the outer periphery of the shoji 4 in the clockwise or counterclockwise direction. Two protrusions 24, 24 are provided on the upper surface of the operating plate 22a of the upper frame 4a and the lower surface of the operating plate 22c of the lower frame 4c at intervals along the length of the operating plate 22. On the other hand, on the inner peripheral surfaces of the upper frame 3a and the lower frame 3c of the window frame 3, two hook portions 25, 25 are formed at the same intervals as the protrusions 24, 24. When the operating plate 22 slides in one direction along the sliding guide 21 in the closed window state, Caused 24, respectively, the corresponding hooking portion 2
The sliding door 4 engages with the sliding door 5 to lock the sliding door 4 in the closed window posture, and when the operating plate 22 slides in the opposite direction, the engagement with the engaging portion 25 of each projection 24 is released. The lock is released, and both projections 24, are formed on the lower surface of the operating plate 22c of the lower frame 4c.
The engaging pins 40 projecting downward between 24 are formed,
On the other hand, the lower frame 3c of the window frame 3 is provided with a drive unit 30 for locking operation that slides the operating plate 22 by being connected to the engaging pin 40.

The drive unit 30 includes a cylindrical base 31 fixed in an elongated recess 3d formed along the lower frame 3c, and a threaded rod 32 parallel to the lower frame 3c in a hollow of a cylindrical base 31. , 32a are fitted to the bearings 33, 33 so as to be supported rotatably and immovably in the axial direction.
The internal threaded body 35 protruding from the
The screw rod 32 is screwed into the guide groove 37 formed along the groove so as not to rotate about the axis of the screw rod 32, and the sliding portion 36 protruding upward from the base 31 of the female screw body 35 is formed. The plate-like connecting portion 38 formed by bending horizontally toward the outdoor side has a connecting recess 39 formed by notching the end edge portion thereof so as to open to the outdoor side. The engaging pin 40 of the actuating plate 22c can be fitted into the connecting recess 39 when the shoji 4 is in a closed window posture in which the lower frame 4c is in contact with the lower frame 3c. .

A lock electric motor 45 is fixed to the end of the base 31, and an overload cutoff clutch 43 is provided between the output shaft 55 of the speed reducer 44 and one journal 32a of the screw rod 32. As shown in the figure, U mounted on the rotating body 56
The output shaft 55 is sandwiched between the flat portions 57a, 57a of the character-shaped leaf spring 57, and the serration shaft portion 5 at the tip of the journal 32a is inserted into the serration hole 58 of the rotating body 56.
The screw rod 32 is connected to the lock electric motor 45 by being inserted by fitting 9 and when the lock electric motor 45 is driven, the leaf spring 57 of the overload cut-off clutch 43 is always provided. One of the flat portions 57a engages with the flat surface 55a on the outer periphery of the output shaft 55, so that the output shaft 55
Is transmitted through the rotating body 56 to rotate the screw rod 32, and the female screw body 35 is inserted between the stoppers 46, 46 fitted to both ends of the screw rod 32, and the operating plate 22c of the lower frame 4c. When the female screw body 35 comes into contact with the stopper 46 to prevent its movement and the rotation of the screw rod 32 to stop, the output shaft 55 is rotated. By rotating one flat portion 57a of the spring 57 while elastically expanding it, the transmission of the rotational force from the lock electric motor 45 to the screw rod 32 is interrupted, and the lock electric motor 45 becomes an overcurrent. It is designed to prevent burning.

The assembly of the drive unit 30 having the above-described configuration to the lower frame 3c is performed by fixing the base 31 to the bottom surface of the recess 3d by a simple means such as screwing (not shown), and opening and closing the lock electric motor 45. This is performed by the work of connecting with a lead wire 48 to the control device 50 to which the opening / closing electric motor 7 of the drive device 5 is connected. The lead wire 48 is attached to the lower frame 3c of the window frame 3. The wiring work is performed in a short time because the wiring is performed along a short and simple route that leads from the corners where the lower frame 3c and the vertical frame 3b are joined to the inside of the body wall 2. .

The present embodiment has the above-mentioned configuration, and when the shoji screen 4 is rotated from the open window state to the closed window posture, the engagement pin 40 on the shoji screen 4 side is fitted into the connection recess 39 on the window frame 3 side. Then, the operating plate 22 is connected to the female screw body 35 so as to be able to move integrally, and in this state, when the lock electric motor 45 is driven by pushing the lock button 52 of the control device 50, the female screw body 35 is moved to the second position. As the actuating plate 22c of the lower frame 4c slides in the same direction as it is screwed in the right direction in the figure, the operation is performed when the female screw body 35 comes into contact with the stopper 46, as shown by the chain line in the figure. The protrusion 24 of the plate 22c is the hook 2 of the lower frame 3c.
5, the actuating plate 22a of the upper frame 4a moves at the same time, and the projection 24 thereof engages with the hooking portion 25 of the upper frame 3a, so that the shoji 4 is locked in the closed window state. After that, by pressing the drive stop button 53, the lock electric motor 45
Is stopped, the movement of the female screw body 35 is blocked because the friction angle is larger than the lead angle at the engaging surface of the screw rod 32 and the female screw body 35, so that the operating plate 22 slides and the projection 24 Does not come off from the hook portion 25, and the locked state is maintained.

Further, when the window is opened from the locked state, the lock release button 54 is pushed to drive the lock electric motor 45 in the opposite direction to the above, and the female screw body 35 is screwed leftward in FIG. As the actuating plates 22 slide in the opposite direction to the above, the projections 24 are disengaged from the hooks 25 and the lock is released. It is sufficient to stop the shoji 4 to rotate in the window opening direction by driving the opening / closing drive device 5,
At this time, the lower frame 4c is separated from the lower frame 3c, so that the engaging pin 40 is disengaged from the coupling recess 39 and the operating plate 22 is removed.
The connection between the female screw body 35 and the female screw body 35 is released, but the movement of the female screw body 35 is blocked by the engagement with the screw rod 32, and the actuating plate 22 is rubbed by the frictional resistance with the sliding guide 21. Since the sliding is restricted, the connecting recess 39 and the engaging pin 40 are held at the same positions as when the mutual engagement is released, so that the lower frame 4c abuts the lower frame 3c by closing the window. When this is done, the engagement pin 40 is smoothly fitted into the coupling recess 39.

In this embodiment, the drive unit 30 is attached to the lower frame 3
c and the engaging pin 40 is provided on the operating plate 2 of the lower frame 4c.
2c, instead of this, the drive unit 30 is provided on the upper frame 3a or the vertical frame 3b and the engaging pin 40
The operating plate 22a of the upper frame 4a or the operating plate 22 of the vertical frame 4b
You may make it formed in b.

Similarly, in this embodiment, the upper frame 3a and the lower frame 3 of the window frame 3 are
Although the shoji 4 is locked by both c, instead of this, by removing the hooking portion 25 of the upper frame 3a and mounting the operating plate 22 only on the lower frame 4c, You may make it lock only by the lower frame 3c.

The present invention is not limited to the horizontal axis rotating window described in the above embodiment, but one vertical frame swings to the outdoor side and the other vertical frame swings to the indoor side around the vertical axis that passes between the left and right vertical frames. The vertical axis rotating window supporting the shoji screen, the projecting window supporting the shoji screen swingably around the upper frame, the tilting window supporting the shoji screen swinging around the lower frame, and the shoji screen on one side. The present invention can also be applied to other types of rotating windows such as a door type swinging window which is swingably supported around a vertical frame.
