The opening/closing arm d of the opening/closing device C is rotated to close the shoji screen.

Further, when the handlebar 4 is rotated upward in the opposite direction to the above, the opening/closing arm d is rotated and the shoji screen is opened.

A conventional handle device is shown in FIGS. 1 to 6, and FIG. 1 shows a perspective view of the conventional handle device,
Let's explain its structure.

A handle lever 4 is pivotally connected to a base 2 protruding from a seat plate 1 via a shaft 3, an arm 6 is pivotally connected to the handle lever 4 via a shaft 5, and an arm 6 is pivotally connected to the arm 6 via a shaft 7. A slider 8 is pivotally mounted, a rod 9 is fixed to the slider 8, and the rod 9 is loosely fitted into a hole 10 of the base 2. In the figure, 11 is a lock nut, 12 is a connecting rod, and the connecting rod 12 operates the opening/closing arm d of the window opening/closing device C.

The general operation of the window opening/closing device and the handle device is as follows: When the handle lever 4 is rotated in the direction of arrow A, the slider 8 moves in the direction of arrow B.
direction, the connecting rod 12 is pulled and the opening/closing arm d of the opening/closing device is rotated to close the shoji screen, and when the handle lever 4 is rotated in the opposite direction of arrow A, the connecting rod 12 is pushed out in the opposite direction to the above and the shoji screen is closed. open the door.

The operation of the handle device shown in FIG. 1 will be explained based on the operation explanatory diagrams of FIGS. 2 to 6 in which the slider 8 is omitted. When the handle lever 4 is rotated in the direction of arrow A in the state shown in FIG. 2, the connecting rod 12 is pulled in the direction of arrow B as shown in FIG. (The connecting rod 12 is pulled to the point where the shafts 3, 5, and shafts are lined up in a straight line (also called the starting and dead center). When the handle lever 4 is further rotated in the direction of arrow A, as shown in FIG. The connecting rod 12 is moved in the direction of arrow C from the point where it passes the consideration point, and the connecting rod 12 returns until it reaches the state shown in FIG. is pulled in the direction of arrow C with a strong force, and the handle lever 4 becomes locked.

As described above, in the conventional handle device, the handle lever 4 is in the locked state, but there is a drawback that the connecting rod 12 is tied over a wide range from the state shown in FIG. 4 to the state shown in FIG. Banking provided on the window frame in order to give a wide return action to the opening/closing arm d of the window opening/closing device connected to the connecting rod 12, and return the shoji to the wide width after closing it more than necessary. This has the drawback of increasing fatigue and damaging the window, and further reducing the sealing effect of the window.

The purpose of the present invention is to eliminate the drawbacks that conventional handle devices had, and by making the arm of the conventional handle device a bifold arm that can be folded in the middle, from the point when it is pulled to the maximum. To provide a handle device which allows a handle lever to be locked by only a small amount of return.

A nozzle device is formed by pivotally connecting a bifurcated arm 13 consisting of 2' and a slider 16 pivotally attached to the bifurcating arm 13 via a shaft 17. A rod 9 is fixed to the slider 16, and a connecting rod 12 is fixed oppositely to the slider 16. The rod 9 is guided by a hole 10 in the base 2, and an opening/closing arm of a window opening/closing device is connected to the connecting rod 12. .

In the figure, 2' is a contact portion on which the shaft 18 comes, and is attached to the base 2 or separately. 14 is a slider bracket that is installed separately or in parallel with the seat plate 1. 14 is provided with an elongated hole 15, into which the shaft 17 which pivotally connects the slider 16 and the bifurcated arm 13 is loosely fitted, so that the slider 16 slides parallelly within the slider bracket 14. It is now able to move.

Note that the bifurcated arm 13 may be pivoted inside the [-4] as a single link instead of as a pair of links 19 and 19'.

The structure of the embodiment of the handle device of the present invention has been described above, and its operation will be explained based on the operational diagrams of FIGS. 13 to 17.

First, as for the overall operation, the handle lever 4 is in the position shown in FIG. 17, and the connecting rod 12 is
The shoji is brought into the open state by the opening/closing arm d of the window opening/closing device connected to the shoji, and from this state, the handle lever 4 is rotated in the direction of arrow A, and the connecting rod 12 is pulled). When it reaches the position, the shoji is closed and in a closed state.

Next, the operation of the handle device will be explained in detail. In FIG. 13, when the handle lever 4 is rotated in the direction of arrow A about the shaft 3, the shaft 17 slides along the elongated hole 15 of the slider bracket 14 via the bifurcated arm 13, and as shown in FIG. As shown, the rod 9 moves in the direction of arrow B, and the connecting rod 12
is pulled in the direction of arrow B, and when the handle lever 4 is further rotated in the direction of arrow B, the shaft 18 of the bifurcated arm 13 comes into contact with the contact portion 2' of the base 2, as shown in FIG. At this time, the shafts 17, 18, and 5 are aligned on the straight line indicated by the dashed line A, and when the handle lever 4 is further rotated, the link 19.
19' rotates around the shaft 18, and further connects the connecting rod 1.
2 is pulled in the direction of arrow B, and the connecting rod 12 is pulled to the state shown in FIG. That is, when the handle lever 4 is further rotated in the state shown in FIG. 15, the shaft 18 moves in the direction of the arrow until the shafts 5, 3, and 18 are lined up on the straight line indicated by the two-dot chain line opening, as shown in FIG. The connecting rod 12 is moved in the direction of arrow B', and the connecting rod 12 is also pulled in the direction of arrow B. When the handle lever 4 is further rotated, the shaft 5 moves to the point indicated by the two-dot chain line (
17, and at this time, as shown in FIG. 18, the inclined protrusion 21 of the link 19 comes into contact with the lower side of the link 22, and the rotation of the handle lever 40 stops. At the same time, the connecting rod 12 of the door door 4 is pulled toward the shoji side, so that it becomes locked.

During the transition from the state shown in FIG. 16 to the state shown in FIG. 17, the shaft 5 rotates beyond the point of consideration, so that the shaft 18 is
Although it returns in the opposite direction, the amount of return is very small because the link 19 is short and the length between the shafts 18 and 5 is short (this point will be described later).

Also, when opening the shoji, move handle lever 4 to the first position.
7 When rotated in the direction of arrow C from the state shown in Figure 7, link 1
The protruding piece 20 of 9 abuts the upper side of the link 22 and the link 19
When the link 22 becomes like an arm and rotates further, it performs the opposite operation to the above-mentioned operation, and the connecting rod 12 is pushed out in the direction opposite to arrow B, opening the shoji.

Here, the handle device of the present invention is different from the conventional handle device in that after the connecting rod 12 is pulled, the handle lever 4
Explain how the amount of return is small when it is in a locked state. By the way, shaft 3 of the conventional handle device (see Figure 6)
, the length between the shafts 5 is 11, the length between the shafts 5 and 7 is 2nd, the length between the shaft 3 and the wand 9 is 3, and the shafts 3 and 7 of the handle device of the present invention (see FIG. 17) are The length between 5 and 18 is 11, the length between axis 3 and wand 9 is , e3, the length between axis 5 and axis 18 is 4th, axis 1
7. The length between the shafts 18 is 5th, and the contact part 2 between the center of the shaft 3 and the base 2

When the torso, ff1a = 20 mm, -6s = 6.5 mm, the amount of return from the maximum tension of the connecting rod 12 is actually measured and compared. (from the state shown in Figure 6) The return distance is 1.2 m.
m, and the return amount in the /% handle device of the present invention (in the states shown in FIGS. 16 to 17) is 0.13wn, which is a very small return amount in the handle device of the present invention.

The structure and operation of the embodiment of the nozzle device of the present invention have been described above, but the present invention provides a mechanism in which the nozzle lever and the slider are pivotally connected by a bifurcated arm, and the bifurcated arm is used as a link. Since the link is pivoted on the shaft, the shaft of the bifurcated arm comes into contact with the contact part of the base, and the
Only the link on the side that is pivoted to the steering lever rotates.
In addition to being able to move the handle lever past the point where it is locked, it is also possible to extremely reduce the amount of return of the slider after pulling the slider to its maximum extent, which in turn makes it possible to connect the handle lever to the handle device. To reduce the amount of return of an opening/closing lever of a window opening/closing device, thereby preventing the backing from being damaged by closing the window more than necessary, and achieving the required sealed state.

In addition, since we have provided an inclined protrusion on the lower side of the link at the rear end extension of the link that forms the two-fold arm, it acts as a stopper when the window is closed and the nozzle lever finishes rotating, and it also serves as a stopper when the window is closed and the nozzle lever is finished rotating. Further rotation of the handle lever can be prevented, and since a protruding piece is provided on the upper side of the link, when the handle lever is rotated to open the window, the pivot links do not bend and move in one direction. It has the effect of being able to do something.
