Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a wire which is supported between a window frame and a window frame by supporting the window frame swingably and biased in the window opening direction. The present invention relates to a device for locking a shoji screen in a window closing state in a swinging opening / closing window in which the window is closed by winding.

Problems to be solved by the conventional techniques and inventions: A shoji is swingably supported on a window frame by being biased in a window opening direction, and a wire routed between the shoji and the window frame is wound up. In a swinging open / close window that is closed by means of a window, a method for locking the shoji in a closed window state is to use a shoji that winds the wire by rotating the winding drum and swings the wire in the window closing direction. At the point of contact with the frame, the driving of the winding drum is stopped and the locking device is operated by a different operation from the driving of the winding drum to lock and open the shoji. Sometimes, the lock of the locking device is first unlocked, and thereafter, the wire is manipulated to swing the shoji in the fenestration direction. Conventionally, the operation of the locking device is performed by winding the drum. It is a separate operation from the driving operation of Since it grew up in the eel, there was a drawback that it took time and labor to open and close the window.

Means for Solving the Problems As a means for solving the above problems, the window locking device of the present invention connects the feeding end of the wire to a swing piece pivotally supported on the window frame and swings the swing piece. Attach a spring to the one piece that pulls the wire toward the payout end and urges the swinging piece to swing to the unlocked position.The rocking direction of the swinging piece resists the biasing force of the spring when the window is closed. One of the hooks of the protrusions that are engaged with each other by the swinging is formed on the swinging piece, and the other is formed on the shoji.

Advantageous Effects and Advantages of the Invention The present invention has the above-mentioned configuration, and when the winding drum is manually or electrically driven to rotate to wind the wire in the open state, the oscillating piece of the oscillating piece is restricted from oscillating by the urging force of the spring. While the wire is being held in the unlocked position, the sliding screen swings toward the window as the wire feeding length becomes shorter, and the winding drum is further wound even after the window is blocked and the sliding screen contacts the window frame. When the drive is continued, the shoji is blocked from swinging by contact with the window frame, so the swinging piece is pulled by the wire and resists the biasing force of the spring in the locking direction. By swinging, the protrusion and the hook are engaged with each other, and by preventing the wire from being fed out by restricting the rotation of the winding drum in the feeding direction, the swinging piece is held in the rocking posture and the shoji screen opens. The rocking in the window direction is blocked and the window is locked. In addition, when the wire is reeled out by releasing the regulation of the rotation of the winding drum from the closed window state, the entire biased wire is pulled toward the reeling end by the biasing force of the spring in the initial stage of the reeling. While swinging and moving, the swinging piece swings in the unlocking direction, and the engagement between the projection and the hook is released, so that the shoji becomes swingable in the window opening direction, and the wire is continued to be fed out. As the payout length increases, the shoji rocks in the window-opening direction and the window opening increases. Since it can be operated in conjunction with the opening / closing operation of the shoji only by rotating it, there is an effect that the work at the time of opening and closing the window becomes easier compared to the conventional case where both operations are performed separately. .

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

In this embodiment, the rectangular window frame 1 provided at a high place on the wall surface is
By the horizontal axes X, X passing through the intermediate heights of the left and right vertical frames 1c, 1c, the shoji 2 is mounted on the upper frame 2a thereof on the indoor side and the lower frame 2b thereof.
Is applied to a horizontal axis rotating window that is supported by being oscillated in the direction of opening and urged in the window opening direction by members (not shown) such as gas stays and springs. An operating box 4 is installed at a lower position of the winding drum 6 by connecting a handle 5 to the winding drum 6 via a non-reversible clutch (not shown). Free rotation is restricted, and when the handle 5 is rotated in both the forward and reverse directions, the rotational force is transmitted and the winding drum 6 is driven to rotate. The base end (not shown) of the window closing wire 8 is connected.

Window closing wire 8 drawn out from the winding drum 6
Is hung between the pulley 9 supported on the right end of the lower frame 1b of the window frame 1 and the pulley 9 supported on the right end of the lower frame 2b of the shoji 2 to extend along the lower frame 1b as shown in FIG. It is guided to the left, is hung between the pulleys 9, 9 supported on the left end of the lower frame 1b and the left end of the lower frame 2b, and is guided upward along the left vertical frame 1c.
The left end of 1a and the left end of the upper frame 2a are hung between the pulleys 9 and 9 and guided to the right along the upper frame 1a, and finally, the right end of the upper frame 1a and the right end of the upper frame 2a. Is routed in such a way that it is hung between the pulleys 9 and 9, and the feeding end 8a of the window closing wire 8 is coupled to the right end of the operating plate 13 provided along the upper frame 1a. A connecting wire 14 having one end coupled to the left end of the operating plate 13 is arranged downward along the left vertical frame 1c, and the other end thereof is an elongated connecting plate 15 provided along the lower frame 1b. Is connected to the left end of the
Between the right end of 15 and the right end of the lower frame 1b, a tension coil spring 16 parallel to the lower frame 1b is mounted, and the elastic plate of the tension coil spring 16 causes the actuation plate 13 and the connecting plate 15 to move. While pulling the window closing wire 8 toward the feeding end 8a, the upper frame 1a or the lower frame 1b
Is urged to move along.

The operating plate 13 along the upper frame 1a is rotatably connected to the swing ends of a plurality of engaging pieces 17 pivotally supported in a vertical plane on the indoor side surface of the upper frame 1a. However, the actuating plate 13 is always positioned on the left side by the urging force of the tension coil spring 16 so that each engagement piece 17 is held in the sideways unlocked posture. When the actuating plate 13 moves to the right against the biasing force, the engaging pieces 17 swing at the same time, and the swinging ends of the engaging pieces 17 assume a locking posture in which they project downwardly into the opening 18 of the window frame 1 to close the window. When the rocking ends contact the upper frame 2a of the shoji 2 from the indoor side, the upper part of the shoji 2 is locked so that it cannot rock in the window opening direction.

Further, in the connecting plate 15 provided along the lower frame 1b, a plurality of swing pieces 22 rotatably supported on the lower frame 1b by a support shaft 20 in a horizontal plane are swingable on the indoor side. Each swing piece 22 is connected so as to swing while maintaining the same posture by supporting the ends of the swing shafts 22 so as to be relatively rotatable, and the swing pieces 22 are connected to the swing end on the outdoor side of each swing piece 22. Are projections formed by rotatably fitting rollers 27 on shafts 26 protruding upward in the vertical direction.
On the other hand, on the surface of the lower frame 2b of the shoji 2 on the indoor side, hooks 29 projecting toward the indoor side and bending to the left side are formed at a plurality of positions corresponding to the swing pieces 22, respectively. Bracket
28 is fixed, the connecting plate 15 is always positioned to the right by the urging force of the tension coil spring 16, and as shown by the chain line in FIG. It is designed so that it is held in a lock release position that is shifted to the left from the position corresponding to the hook 29 of No. 2, and the tension coil spring 16
When the connecting plate 15 moves to the left against the urging force of
Each swing piece 22 swings all at once while 15 draws an arc, and the second
As shown by the solid line in the figure, the projection 25 takes a rocking position corresponding to the position where it engages with the hook 29.

The present embodiment has the above-described structure. When the window is closed from the open state, the handle 5 of the operation box 4 is manually rotated to wind the window closing wire 8 around the winding drum 6. , Due to the urging force of the tension coil spring 16, the upper frame 1a
The engagement piece 17 and the swing piece 22 of the lower frame 1b are kept in the unlocked posture, and the movement of the feeding end 8a of the window closing wire 8 connected to the operating plate 13 is restricted, Window wire 8
As the feeding length of the shoji screen becomes shorter, the shoji screen 2 swings from the tilted posture to the standing direction, and the opening degree of the window becomes smaller.
The window is closed by the upper frame 2a and the lower frame 2b coming into contact with the upper frame 1a and the lower frame 1b, respectively.

When the window-closing wire 8 is continuously wound even after the window is closed, the swinging of the shoji screen 2 is prevented by the contact with the window frame 1. As the actuating plate 13 and the connecting plate 15 move while the tension coil spring 16 is extended, the engaging piece 17 and the swinging piece 22 swing into a locking posture, and the engaging piece 17 causes the shoji 2 to move. At the same time that the upper frame 2a of the rocking piece 22 is locked, the projection 25 of the rocking piece 22 engages with the hook 29 of the shoji 2 to prevent the lower frame 2b of the shoji 2 from separating from the lower frame 1b. The lock operation is completed by the
When the operation is stopped, the rotation of the winding drum 6 is blocked by the action of the irreversible clutch, so that the window closing wire 8 is not paid out, and the shoji 2 is in a state in which it cannot swing in the window opening direction. Locked.

When the window is opened from the closed window lock state, the window closing wire 8 is fed out from the winding drum 6 by rotating the handle 5 in the opposite direction to the above-mentioned state. The entire window closing wire 8 that has been pulled out is the feeding end 8a.
Tension coil spring that was stretched while moving to the side
By the elastic contraction of 16, the engaging piece 17 and the swing piece 22 swing from the locking posture to the unlocking posture, whereby the locking is released and the shoji 2 can swing in the window opening direction. When the window closing wire 8 is continuously fed out after this, the shoji 2 tilts due to the urging force in the window opening direction to increase the opening of the window, and when the window reaches an arbitrary opening, the handle When the operation of 5 is stopped, the feeding of the window closing wire 8 is stopped by the action of the irreversible clutch, so the tilting of the shoji 2 is prevented and the window is held at a constant opening.

Since the present embodiment is applied to the horizontal axis rotating window, it is adapted to lock both the upper side and the lower side of the window, which ensures that the shoji 2 in the window closing state is locked. To be done.

In this embodiment, since the length from the axis X, which is the swing center of the shoji screen 2, to the upper frame 2a and the lower frame 2b, which are the swing end edges, is short, the upper frame 1a
Although the window locking is performed between the upper frame 2a and the lower frame 2a and between the lower frame 1b and the lower frame 2b, when the dimension from the axis X to the upper frame 2a or the lower frame 2b is large, the engaging piece 17 Alternatively, attach the swing piece 22 to the upper frame.
Instead of 1a or the lower frame 1b, it is provided at the upper end or the lower end of the vertical frame 1c so as to engage with the upper end of the vertical frame 2c of the shoji 2 or engage with the hook 29 provided at the lower end thereof. You may

Further, in this embodiment, the protrusion 25 is attached to the swing piece 22, and the hook 29 is attached.
However, the projection 25 is provided on the shoji screen 2 on the contrary.
Alternatively, the hook 29 may be provided on the swing piece 22.

Similarly, in this embodiment, the winding device 4 is driven by the manual operation of the handle 5, but instead of this, it may be driven by an electric motor.

Further, as means for restricting the rotation of the take-up drum 6 in the feeding direction, other than the non-reversible clutch described in the above embodiment, other means such as engagement between the worm and the worm wheel and engagement of the claw with the ratchet wheel are used. Means may be used.

The present invention is not limited to the horizontal axis rotating window described in the above embodiment, but the vertical axis rotating window for swinging the shoji about the vertical axis provided in parallel between both vertical frames, and the shoji for its upper frame. The present invention can also be applied to other types of swing opening / closing windows such as a protruding window that swings to the outdoor side around the center.
