  SUMMARY OF THE INVENTION An object of the present invention is to provide a sliding window opening / closing device that can be easily switched between an internal and external shoji to be opened and closed and can be remotely operated.

The present invention relates to a sliding window opening and closing device comprising an inner and outer obstacle, and includes a belt-type driving device for opening and closing the inner and outer obstacle, and the belt is disposed in parallel with the inner and outer obstacle. And a cam for a shingles and a cam for a shingles that can be switched between a locked state and a released state, respectively. And the external shoji has a block for external shoji that is engaged with the cam for external media, and in the state in which the cam for internal media is locked to the block for internal media, the internal pouch is opened and closed by the belt, In the state in which the cam for the screen is locked to the block for the screen, the screen is opened and closed by the belt.
As described above, of the cams for the inner and outer children and the cams for the outer child that are attached to the belt, when the inner cam is locked (engaged) with the inner arm block, the inner child is opened and closed by the forward and backward movement of the belt. If the cam for the shoji is locked to the block for the shoji, the shoji can be opened and closed by the advance and retreat of the belt.

In the present invention, various means can be adopted as the means for switching between the locked state and the released state of the cam block.
For example, as a simple structure, the cam for the inner limb and the cam for the outer limb can be switched and held between a locked state and a released state for the inner block and the outer block by the turnover spring, respectively. An example is given.
Further, as the switching and holding means, a cam for inner limbs attached to the belt comes into contact with the movement of the belt and has a release stopper that is in a released state and a return stopper that is in a locked state, and is attached to the belt. It is possible to have a stopper for an external obstacle that makes contact with the movement of the belt and switches the turn of the external obstacle cam.

  In the present invention, if the belt is disposed in parallel with the inner and outer shoji, two belts for inner and outer shoji may be used, but the drive device can be remotely operated with a simple structure in a centralized manner. In this respect, the belt is preferably an endless belt.

The sliding window opening and closing device according to the present invention can be easily switched between opening and closing of the inner and outer obstacles by engaging and switching the cam attached to the belt and the block provided on the inner and outer obstacles. Yes, it can be operated remotely.
Further, since it is a combination of a cam and a block, manual operation for switching and special drive means are unnecessary, and the structure is simple.

The structure of the switchgear concerning the present invention is typically shown. Shows opening and closing of a shoji and switching to a shoji.

  A structural example of a sliding window opening and closing device according to the present invention will be described below with reference to the drawings, but the present invention is not limited to this.

As shown in FIG. 1, the opening / closing device has an endless belt 33 arranged in parallel to the inner and outer sliding members 10 and 20 that slide inside the sliding window.
The belt-type drive device 30 has a belt 33 stretched between a drive wheel 31 and a driven wheel 32, an inner belt portion 33a is disposed along the inner shroud 10, and an outer belt portion 33b is provided. Arranged along the shoji 20.
The drive device 30 is remotely controlled by a remote controller or the like.
The belt 33 includes an inner cam 33 for opening and closing the inner shoji and an outer cam 35 for opening and closing the outer shoji.
On the other hand, the inner shoji 10 includes the inner shoji block 11 to which the inner child cam 34 is locked,
The external shoji 20 is fixed with an external shroud block 21 to which the cam 35 for external shoji is locked.
The inner child cam 34 and the outer child cam 35 are attached to the belt 33 so as to be rotatable by rotation shafts 34a and 35a, and abutting against a stopper, which will be described later, and action portions 34b and 35b for rotating the cam. The inner / outer shoji blocks 11 and 12 have hook-shaped engaging portions 34c and 35c that are engaged with the concave portions 11a and 12a.
Further, the cams 34 and 35 for inner and outer shoji are provided with turnover springs between the turn pins 34d and 35d and the rotation shafts 34a and 35a, and the cams 34 and 35 are rotated to block the blocks 11 and 21. And a released state in which the cams 34 and 35 are rotated in a direction to release the locked state.

The action part 34b of the cam 34 for the inner limb comes into contact with the inner limb, and the release stopper 12 for switching the cam 34 for the inner limb to the release state, and the return stopper 13 for switching the cam 34 for the inner limb to the locked state. Have
The action part 35b of the cam for outer arm 35 abuts on the side of the outer arm, and has an outer claw 22b for rotating the outer arm cam 35 in the releasing direction and a return protrusion 22a for rotating in the locking direction. A shoji stopper 22 is provided.

Next, the opening / closing operation of the shoji will be described.
FIG. 1 (a) shows a state where the locking portion 34c of the cam for inner pouch 34 enters and locks into the recess 11a of the block 11 for inner stroke, and this state is between the turn pin 34d and the rotating shaft 34a. It is maintained by a provided turnover spring.
The locking portion 35c of the outer arm cam 35 is disengaged from the recess 12a of the outer arm block 12, and is in a released state.
The disability cam 35 is also maintained in a released state by a turnover spring provided between the turn pin 35d and the rotation shaft 35a.
When the belt 33 is rotationally moved in the direction of arrow A in this state, the inner pouch is opened.
Therefore, when the belt 33 is moved forward and backward in the state shown in FIG.
As shown in FIG. 1 (b), the inner limb 10 is pulled by the inner limb cam 34 in the opening direction, but the outer limb 20 has the outer limb cam 35 in the released state. Just move on.

When the belt 33 is rotated in the direction of arrow B as shown in FIGS. 1 (c) and 1 (d), the action portion (action pin) 34b of the inner limb cam comes into contact with the release stopper 12 and rotates in the release direction. The release state of the cam for the inner child is maintained by the turnover spring.
On the other hand, the cam 35 for the shoji is rotated in the locking direction by the return projection 22 a provided on the stopper 22 for the shoji.
At this time, the contact with the upper surface portion 21b of the cam for disability 21 is shown as an example. However, when the belt 33 is rotated in the direction of arrow A as shown in FIG. The latching portion 35c of the shoji cam is latched in the recess 21a of the block for shoji 21, and the shoji 20 is opened.
In this state, the armature 20 is in the armature opening / closing mode in which the armature 20 is opened / closed by the forward / backward movement of the belt 33.
When the belt 33 is rotated to the state shown in FIG. 2A, the cam for inner pouch 34 is rotated by the inclined portion of the return stopper 13 in the locked state.
In this state, when the belt 33 is rotated in the direction of arrow B as shown in FIGS. 2B and 2C, the locking portion 34c of the inner child cam 34 extends along the inclined surface portion 11b of the inner child block 11. The catching part 34c is latched to the recess 11a of the block for inner limbs 11 by the return force of the turnover spring.
On the other hand, as shown in FIG. 2 (d), the action portion 35 b of the external arm cam 35 abuts on the release claw portion 22 b of the external door stopper 22 and rotates toward the release state.
As a result, the state shown in FIG.

  When such an opening / closing device is adopted, the rotation direction and range of one endless belt can be remotely controlled to select the inner / outer opening / closing mode and the outer / outer opening / closing mode, respectively. The open / close mode can be switched.
