2. Description of the Related Art Conventionally, in a window in which a shoji is openably and closably attached to a window frame via a vertical axis, an arm is swingably connected to the window frame near the vertical axis in order to keep the shoji open halfway. On the other hand, the sliding door is provided with a pin which is engaged with the arm, and the engaging hole is formed in a long hole, and the elongated hole is provided with a cutout portion in which the pin is engaged when the sliding door is halfway open. I was

[0003]

However, in the above-mentioned conventional halfway opening stop mechanism, the arm is fixed by the notch of the arm and the pin of the sash, and thereby the sash is held halfway. However, since the holding of the shoji is based on the simple catching of the notch and the pin, it can be dislodged by the wind at places where strong wind blows, such as the outer window, or the shoji can be opened halfway. There is a risk of opening and closing, and it is very dangerous to open the windows of a high-rise building or windows that open from the feet, such as windows in curtain walls, so it is desirable that these windows be held halfway.

In view of the above-mentioned circumstances, the present invention provides a mechanism for stopping the sliding door to be stopped halfway when the window is opened by operating the steering wheel from the room, and the sliding door is not fully opened. The purpose was to.

[0005]

In order to achieve the above-mentioned object, the present invention provides a sliding door which can be moved in a horizontal frame at a vertical opening / closing window which intersects a window frame through a vertical axis. A mounted moving body, an arm having one end pivotally connected to the window frame and the other end pivotally connected to the moving body, and a knob for indoor operation at a base end side of which is in contact with an upper surface of the moving body. A stopper member provided on the side frame, a biasing member for biasing the both stopper pins toward the moving body, and a tip of the moving body provided on the side frame in a moving direction of the moving body. , A biasing member for biasing the one-side stopper pin downward, and a movement in which the ends of the two-sided stopper pin are located when the tip of the moving body contacts the one-side stopper pin. Opened halfway through a pit provided in the body To constitute a stop mechanism.

[0006]

Since the mechanism for stopping the opening of the vertical opening window halfway is configured as described above, when the shoji is opened indoors, the moving body moves in the direction of the base end of the horizontal frame of the shoji, in relation to the arm. When the halfway opening angle is reached, the ends of the both stopper pins fall into the drop holes of the moving body, and the halfway opening state is immovable in either opening or closing direction. Also, at the same time, since the moving body hits one stopper pin, even if you lift the knobs of both stopper pins and remove both stopper pins from the holes, the sliding door can not be opened any more, only closing the sliding door Becomes possible.

[0007]

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 to FIG. 9 show an example in which a vertical axis opening / closing window provided also as an emergency exit in a curtain wall is used. At the left end (as viewed from the side), an opening / closing longitudinal axis 1 is provided, and the opening is attached to the outside.

As shown in FIGS. 1 to 3,
It is framed by left and right vertical frames 2a, 2b and upper and lower frames (horizontal frames) 4a, 4b, and a sheet glass 6 is provided in this frame. The shoji S is provided with an internal handle 5 for indoor operation, a release knob 7a for a stop mechanism T described later, and an external handle 9 for outdoor operation. The opening can be canceled by the operation of the release knob 7a, and the halfway opening can be released through the release mechanism R described later. However, the operation of the internal handle 5 does not allow the sash S to be fully opened, but can be fully opened only by the external handle 9. A mechanism R is provided.

The vertical axis 1 is slightly moved to the open side by the opening and closing of the sash S with respect to the window frame F by a known link mechanism (not shown). The window frame F and the lower frame 4b of the shoji S are connected by an arm 3, and the arm 3 is pivotally supported at the base end by the lower frame 11 as shown in FIGS. The pivot pin 17 pivotally supported by the lower frame 4b of S and supporting the distal end thereof can move in the proximal direction (left side) with the open state of the shoji S. In the following, the term "proximal side" indicates the side of the vertical axis 1 of the shoji screen S.

The main part of the stop mechanism is provided in the lower frame 4b as shown in FIG. Briefly explaining the outline, when the sliding door S is opened by releasing the inner handle 5 shown in FIG. 6, the moving plate (moving body) 10 connected to the tip of the arm 3 by the pivot pin 17 is indicated by an arrow in FIG. Move left to show
Since the both stopper pins 7 fall into the drop holes 12 provided in the moving plate 10 and at the same time, the tip 79 of the moving plate 10 abuts on the lower end of the one stopper pin 8 provided on the left side of the both stopper pins 7, The shoji S stops at an opening of 15 degrees.

In order to close the sash (S), it is possible to lift the two stopper pins (7) with the knob (7a) and pull it up from the drop hole (12) to return the sash (S) to its original position. However, even if the both stopper pins 7 are lifted, the sliding board S cannot be opened any more because the moving plate 10 abuts against the one stopper pin 8. To fully open, an external handle 9 described later
Need to be manipulated.

The inner handle 5 locks and unlocks the window frame F by means of a ratchet provided on one of the vertical frames 2b, similarly to a normal handle.
A one-way interlocking mechanism 19 is provided between the internal handle 5 and the external handle 9 so that the operation can be performed only from the external handle 9 to the internal handle 5.

As shown in FIG. 6, the one-way interlocking mechanism 19 has a leading interlocking rod 21 which moves left and right in conjunction with the swing operation of the internal handle 5 inside the lower frame 4b. 21 and the driving rod 23 by the external handle 9
5, a long hole 25 is provided in the leading interlocking rod 21, and a connecting pin 27 engaging with the long hole 25 is protrudingly provided in the driving rod 23. When the inner handle 5 is in a locked state, the connecting pin 27 is located on the left side of the elongated hole 25 (the base end side of the sliding door S) in the figure. Since the long hole 25 moves to the left, the operation of the internal handle 5 does not reach the drive rod 23. However, in the locked state, the external handle 9
Is operated, the driving rod 23 moves to the left, and accordingly, the leading interlocking rod 21 moves to the left and moves, and the inner handle 5 is turned to unlock. At the same time, the movement of the driving rod 23 is transmitted to the release mechanism R, and the release mechanism R
In this case, both the stopper pin 7 and the one stopper pin 8 are lifted, and the released state is maintained.

As shown in FIG. 7, the outer handle 9 is pivotally supported by the lower frame 4b so as to be horizontally rotatable by a vertical axis 25. The shape of the outer handle 9 is such that the front end thereof is perpendicular to the lower frame 4b. The operating piece 27 is L-shaped so as to protrude, and protrudes from the shaft support portion at a right angle, and the operating piece 27 is provided with a long hole 29. The driving rod 23 is provided with an engaging pin 31 for engaging with the elongated hole 29. In addition, external handle 9
Since the finger hook 33 is protruded upward at the tip of,
When you pull it while holding it, the external handle 9
And the driving rod 23 moves to the left in the figure by the engagement between the elongated hole 29 and the engaging pin 31.

As shown in FIG. 5, the drive rod 23 is provided below the lower step wall 43 provided in the lower frame 4b. On the other hand, an operation frame 35 for moving the both stopper pins 7 and the one stopper pin 8 is provided above the lower step wall 43. The connection between the drive rod 23 and the operation frame 35 is performed by screwing a connecting plate 37 to an end of the operation frame 35, and providing a long hole 45 in the lower step wall 43 in a range where the drive rod 23 can move.
The drive rod 23 and the connecting plate 37 are connected to each other by a pin 39 protruding from the drive rod 23 via the pin 5.

For mounting the both stopper pins 7, an insertion sleeve 47 through which the both stopper pins 7 are vertically movable and a cup 49 fixed thereon are used, and the insertion sleeve 47 is inserted into the lower frame 4b. The upper and lower walls 41 and 43 are provided so as to penetrate and fix the cup 49.
A coil spring (elastic member) 51 for urging the both stopper pins 7 downward is provided therein, whereby the lower ends of the both stopper pins 7 are pressed against the movable plate 10.

The one stopper pin 8 is attached slightly closer to the proximal end side of the shoji S than the both stopper pins 7.
As for the attachment, the bag sleeve 53 whose upper end is sealed is penetrated and fixed to the upper and lower step walls 41, 43 of the lower frame 4b, and the stopper pin 8 is urged downward at the upper end of the bag sleeve 53. A coil spring (elastic member) 54 is provided, and the lower end of the one stopper pin 8 projects downward from the lower step wall 43 by its elasticity. Since the bag sleeve 53 is fixed to the upper step wall 41 with screws 42, when it is absolutely necessary to fully open the shoji S on the indoor side, the screws 4 are required.
2 and one stopper pin 8 can be removed.

As shown in FIGS. 8 and 9, the operation frame 3 is provided on both the stopper pin 7 and the one stopper pin 8.
The engagement shaft 5 is engaged with the upper end surfaces of the side walls 67 on both sides of the shaft 5.
5 and 57 penetrate and protrude from the peripheral surfaces of the pins 7 and 8 and are fixed. The insertion sleeve 47 and the bag sleeve 5
3 has guide grooves 59 and 61 formed of long grooves through which the engagement shafts 55 and 57 are inserted, along the axial direction of the insertion sleeve 47 and the bag sleeve 53.

The operation frame 35 is held on the lower step wall 43 of the lower frame 4b so as to be movable left and right. The operation frame 35 is formed in a U-shaped cross section, and the bottom thereof has an insertion sleeve as shown in FIG. The through holes 63 and 65 between the bag sleeve 47 and the bag sleeve 53 are formed into slots having a predetermined length corresponding to the moving range.
8, an upper end surface 69a and a lower end surface 69b in relation to the both stopper pins 7 and an upper end surface 71a and a lower end surface 71b in relation to the one stopper pin 8, as shown in FIG. When the operation frame 35 moves toward the base end (left side in the figure) of the shoji S, the engagement shafts 55 and 57 of the both stopper pin 7 and the one stopper pin 8 are inclined. 7
The guides 3 and 75 guide the guides to the upper end surfaces 69a and 71a, respectively, and enter a release state.

As shown in FIG. 9, the movable plate 10 can be mounted by providing a dovetail groove 77 on the lower surface of the lower step wall 43 of the lower frame 4b and fitting it into the dovetail groove 77. The pivot pin 17 is pivotally supported at an end of the moving plate 10 in the proximal direction, and the drop hole 12 is provided at a more distal end side than the pivot pin 17 at an interval. In the closed state, the distance from the center of the both stopper pins 7 to the drop hole 12 and the distance from the base end 79 of the moving plate 10 to the one stopper pin 8 are set to be equal.
When 0 moves that distance, the sliding door S is opened halfway through 15 degrees.

Next, the operation of the opening / closing window having the above structure will be described. First, when the lock is released by the inner handle 5 and the shoji S is opened, the moving plate 10 of the halfway opening stop mechanism T moves with the movement of the arm 3 and the both stopper pins 7 are moved.
In this case, the sliding door S is fixed in both the open and closed directions during the halfway opening, and the open state with the opening degree of 15 ° is maintained. In this case, even if the both stopper pins 7 are lifted by hand, since the front end 79 of the moving plate 10 abuts against the one stopper pin 8, the shoji S cannot be opened but can only be closed.

When the opening degree is 15 °, the two engaging shafts 5
5 and 57 are on the lower end surfaces 69b and 71b of the operation frame 35, and when the external handle 5 is operated, the engagement shaft 5 is connected to the upper end surfaces 69a and 71a of the operation frame 35 via the inclined surfaces 73 and 75.
Since the two stopper pins 7 come out of the drop holes 12 and the one stopper pin 8 comes off the base end 79 of the moving plate 10 by lifting
The moving plate 10 can move in the proximal direction, and the shoji S can be fully opened.

When the external handle 9 is operated in the state in which the sliding door S is closed, the stopper pin 7 and the one stopper pin 8 are also lifted by the movement of the operation frame 35 at this time. There is no obstacle to the movement of the plate 10, and the shoji S can be fully opened.

[0025]

[Effects of the Invention] As described above, according to the present invention,
When the shoji is opened indoors, the moving body moves toward the base end of the shoji, and when it reaches a predetermined halfway opening angle, the tips of both stopper pins fall into the drop holes of the moving body, and the opening and closing direction is In this case, the movable body abuts against the one stopper pin at the same time, so that the movable body cannot be further opened, and the safe halfway open state is maintained. In this case, even if the release knob is lifted and both stopper pins are removed from the drop holes, the end of the moving body abuts against one of the stopper pins, so that even if it can be closed, the sliding door will not be opened any more,
There is an excellent effect that the danger of accidentally opening the shoji from the indoor side can be prevented beforehand.
