Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door opening / closing device in which a sliding opening / closing door can be opened / closed by swinging by adding a simple device to the door without lowering the door.

[0002]

2. Description of the Related Art Generally, as shown in FIG.
It has 0 and the fitting door 11, and the opening / closing door 10 is blind 15
In the device that opens and closes between the pillars 14 by the traveling wheels 19 while being hung on the upper rail 16 inside, if the opening / closing door 10 is opened by swinging with the turning fulcrum portion 12 as a fulcrum, the fitting door 11 is also swung fulcrum. It is known that the portion 13 is opened with the fulcrum as a fulcrum to obtain a width twice as wide as the opening width by sliding.

When the opening / closing door 10 is opened by swinging, the opening / closing door 10 can be fitted at the completely closed position, the completely opened position, or the middle of the opening by pushing the opening / closing door 10. Swing together with killing door 11 and open / close door 10 with opening
Can be moved to the fully open position. In this case, since the opening / closing door 10 must swing while supporting the full load at the upper swing fulcrum portion 12,
There is a problem that the door is lowered. In order to solve this problem, conventionally, the swing shaft 23 is thickened to be inserted into a standing frame, or a cam is provided so that the door tip is gradually lifted as the swing is performed. In order to prevent the vehicle from moving when turning, a method was used in which it came into contact with a cam or the like to provide resistance.

[0004]

However, in the conventional device, the simple structure is not enough to prevent the heavy door from falling down, and if it is attempted to completely prevent the door from falling down, it is not possible. The internal mechanism became complicated, and it was almost impossible to completely prevent the door from falling down, especially with a door without a vertical frame.

The present invention is directed to an opening / closing door 10 that slides and opens.
It is an object of the present invention to provide a door opening / closing device that can be opened and closed by swinging by completely adding a simple device to the upper frame 50 and the hanging frame 18 to completely eliminate the descent of the door.

[0006]

According to the present invention, the opening / closing door 10 is suspended by the swing shaft 23 and the latch 24 on the suspension frame 18 to enable the slide opening / closing, and the swing shaft 23 can be used as the fulcrum to open / close the swing. In this door, a sliding plate 30 is movably provided on the hanging frame 18 by a predetermined distance, and the opening / closing door 1 is attached to the hanging frame 18 and the sliding plate 30.
0 is provided with a holding means for holding the fixing member 22 when fully opened, and a link mechanism for restricting movement and fixing of the hanging frame 18 and the sliding plate 30 is provided, and the holding mechanism is driven by the link mechanism. It is a door opening / closing device including a locking means for holding and releasing the door.

[0007]

The opening / closing door 10 is opened and the sliding plate 30 is fixed to the fixing member 2.
Upon contact with 2, the suspension frame 18 further moves together with the opening / closing door 10, the hook 48 rotates about the pin 47 as a fulcrum, and the stop notch 46 and the attachment portion 49 hold the door stop 22 as a fixing member. To do. In this state, the knob 29 is used to lower the lock forward / backward rod 27. Furthermore, the suspension frame 18 and the opening / closing door 10 are moved a little, and the first link 35 and the second link 36 are moved.
The sword is finally a straight line. Here, when the opening / closing door 10 is pushed out to the side and opened by a swing, the hanging frame 18 and the sliding plate 30 are fixed by holding the fixing member 22, so that only the opening / closing door 10 and the swing shaft 23 are steady. The protrusion 55 is used as a fulcrum to open by swinging.
Since the first link 35 and the second link 36 are aligned with each other, the fixing member 22 is still held by the stop notch 46 and the holding portion 49 and cannot be closed.

When the opening / closing door 10 is returned to its original position and the locking / retracting rod 27 is projected upward, the first link 35 and the second link 36 are bent in a dogleg shape. By the movement of the hanging frame 18, the hook 48 is rotated by the guide pin 32 at one end to release the holding by the holding portion 49, and the engaging piece 34 also digs under the locking plate 28. The slide plate 18 and the sliding plate 30 perform a slide opening / closing operation integrally with the opening / closing door 10.

Next, the structure of the portion added by the present invention will be described. Inside the space 51 of the upper frame 50, a lock advancing / retracting rod 27 that is moved up and down by a knob 29 is provided near the latch 24, and a locking plate protruding laterally to the upper end of the lock advancing / retracting rod 27. 28 is integrally provided.

The suspension frame 18 is provided on the suspension frame 18 with the locking and retracting rod 2.
A lock hole 52 is formed for allowing the locking plate 28 to project to the upper surface of the suspension frame 18 through which 7 penetrates. Further, three guide pins 32 are provided on the side surface of the hanging frame 18 at predetermined intervals, pins 44 are attached thereto, and a support frame 37 is fixedly attached to the upper surface thereof. Although the guide pin 32 is a round bar in the illustrated example, it is preferable that it has a head like a bolt or a nail.

A sliding plate 30 is provided on the side surface of the suspension frame 18 so as to be slidable in the horizontal direction by a predetermined distance. The sliding plate 30 has a long hole 3 that fits with the guide pin 32.
1 has a predetermined length in the length direction. Further, at the other end of the sliding plate 30, a link long hole 33 is formed with the same length as the long hole 31, and an engaging piece 34 for engaging and disengaging with the locking plate 28 is provided. It is provided. A stop notch 46 is formed at one end of the sliding plate 30,
A hook 48 is rotatably provided by a pin 47. The hook 48 has a clasped portion 49 formed on an upper portion thereof, and a swirl elongated hole 53 formed on a lower portion thereof.

The second link 3 is inserted in the link long hole 33.
6, the other pin 39 of 6 is fitted, one pin 38 of the first link 35 is fitted to the support frame 37 fixed to the suspension frame 18, and these first link 35 and second link 36 are , Are connected by a central pin 40. A coil spring 41 for tensioning is interposed between the other pin 39 and the pin 43 of the sliding plate 30. A push-up piece 45 that integrally swings is provided on the lower surface of the first link 35, and the lower end portion faces the upper surface of the locking plate 28. A coil spring 42 for tensioning is interposed between the intermediate portion of the sliding plate 30 and the pin 44 on the side surface of the suspension frame 18.

A hook 48 is rotatably provided at one end of the sliding plate 30 by a pin 47, and the hook 48 is rotated by a guide pin 32 of the suspension frame 18 to be a hooked portion 49 of the hook 48. A holding means is constituted by the stop notch 46 of the sliding plate 30 so as to hold the door stop 22 as a fixing member.

A first link 35 rotatably attached to the suspension frame 18 side and a second link 36 rotatably and movably attached to the link elongated hole 33 of the sliding plate 30 are centrally located. Is rotatably connected by a pin 40 and a coil spring 41 for pulling is provided at an end of the second link 36 to form a link mechanism.
The link 36 is aligned with the link 36 to fix the mutual movement of the suspension frame 18 and the sliding plate 30.

The locking / retracting rod 27 provided on the opening / closing door 10 is projected through the lock hole 52 formed in the suspension frame 18, and the link mechanism of the first link 35 and the second link 36 is bent to suspend the suspension frame 18. The locking means is configured to release the mutual fixing between the sliding plate 30 and the sliding plate 30 and to restrict the swinging of the opening / closing door 10 due to the swing.

On the lower surface of the opening / closing door 10 and on the same vertical axis as the swing shaft 23, there are provided steady rest projections 55 formed by cutting both side surfaces of a cylindrical body in parallel.
In addition, as shown in FIG. 4, the outer side is wide and the central circle is on the same vertical axis as the swing shaft 23 when the opening / closing door 10 is completely opened, which is close to one end of the lower rail 17. A horseshoe-shaped lower swivel plate 54 is provided in which the guide port 57 is cut out so that the hole portion 56 side becomes narrow.

The operation of the above configuration will be described. (1) Opening / Closing by Swing FIG. 1 shows the opening / closing door 1 with the lock forward / backward rod 27 lowered.
0 is completely open, and in this state, opening and closing by swinging is possible. To explain the process until this state is reached, when the locking / retracting rod 27 is raised, as shown in FIG. 3, the first link 35 and the second link 36 remain together with the hanging frame 18 in a doglegged state. The other pin 39 is pulled by the coil spring 41 and is in contact with the left end of the link elongated hole 33 in the figure. The opening / closing door 10 is opened as it is, and the stop notch 46 at one end of the sliding plate 30 is moved to the door stop 22 as shown in FIG. 6A.
When it comes into contact with the sliding plate 30, the sliding plate 30 cannot move any more, but the suspension frame 18 does not open the open / close door 10, the traveling wheel 19, the wheel support frame 20.
At the same time, it moves further to the right in the figure.

Therefore, as shown in FIGS. 6 (b) and 6 (c), the guide pin 32 at one end causes the hook 48 to rotate about the pin 47 as a fulcrum, and the clasped portion 49 is lifted up, and the stop notch 46 is formed. The door stop 22 is held by the holding portion 49. In this way, the engagement piece 34 stops together with the sliding plate 30 and the locking plate 28 moves together with the opening / closing door 10, so that the engagement between the engagement piece 34 and the locking plate 28 is released. In this state,
The knob 29 lowers the locking / retracting rod 27.

Further, the suspension frame 18 and the opening / closing door 10 are moved a little, and the ends of the wheel support frame 20 come into contact with the stopper 21 to stop. At this time, since the one pin 38 also moves due to the movement of the suspension frame 18, the first link 35 and the second link 36.
The cross-shaped shape is gradually lowered and finally becomes a straight line, but the other pin 39 is in contact with the left end of the link elongated hole 33. The guide pin 32 is in the state of FIG. 1 in contact with the right end of the elongated hole 31 in the figure. In this state, the hanging frame 18 that suspends the opening / closing door 10 and the side sliding plate 30 are completely integrated, and at the same time, the steady rest projection 55 at the lower end of the opening / closing door 10 is attached to the lower swing plate 54. It fits in the circular hole portion 56.

When the opening / closing door 10 is pushed out to the side and opened by swinging, the hanging frame 18 and the sliding plate 30 are fixed by holding the door stop 22.
Only the swing shaft 23 and the steady rest projection 55 are used as fulcrums to open by swinging. Since the steady rest projection 55 is fitted in the guide port 57, even if the steady rest projection 55 is rotated a little, the leftward and rightward movements thereof are restricted and the shift is prevented. Even when the opening / closing door 10 is closed by sliding in the state shown in FIG. 1, the door stop 22 is held by the stop notch 46 and the attachment portion 49 because the first link 35 and the second link 36 are aligned. It's up to you and you can't close it.

(2) Opening / closing by sliding In FIG. 1, the opening / closing door 1 that was opened by swinging
0 is returned to the state shown in FIG. 1 and the knob 29 is manually turned to project the locking advancing / retracting rod 27 through the lock hole 52 and project upwards. The locking plate 28 at the upper end of the locking advancing / retreating rod 27 pushes up the pushing piece. 45 is pushed up, the first link 35 and the second link 36 are bent in a dogleg shape against the coil spring 41, and the state shown in FIG. 2 is obtained. That is, the other pin 39 contacts the right end of the link elongated hole 33. Since the guide pin 32 of the long hole 31 is already in contact with the right end, when the opening / closing door 10 is tried to be closed, the hanging frame 18 keeps the first link 35 and the second link 36 in a doglegged shape, and the opening / closing door 10 is for locking. The advancing / retreating rod 27 and the locking plate 28 start moving integrally with each other, and the sliding plate 30 stays at a position for a certain distance.

By moving the suspension frame 18, the hook 48 is rotated counterclockwise in the figure by the guide pin 32 at one end to release the holding by the holding portion 49. By the movement of the suspension frame 18, the guide pin 32 comes into contact with the left end of the elongated hole 31 in the drawing, and the engaging piece 34 also digs under the locking plate 28 to be in the state of FIG. After that, the suspension frame 18 and the sliding plate 30 open and close together with the opening and closing door 10.

Incidentally, in FIG. 3, the forward / backward moving rod 27 for lock is used.
Even if an attempt is made to lower it, it cannot be lowered during the opening and closing by sliding the opening / closing door 10 because the engaging piece 34 is locked to the locking plate 28. Further, even if the opening / closing door 10 is to be rotated by a swing with the lock advancing / retreating rod 27 being raised, it cannot be rotated because it is fitted into the lock hole 52 of the suspension frame 18. Although the door stop 22 is used as the fixing member in the above embodiment, the present invention is not limited to this, and another member other than the door stop 22 may be provided.
