  Hereinafter, a preferred embodiment in which a detachable piece storage portion and an operation handle storage portion of a screen door are provided so as to be flat on a window frame having a sash window frame structure of the present invention will be described with reference to the drawings.

First, a description will be given of a structure in which an operation handle storage portion is provided in a window frame of a sash (hereinafter, referred to as a sash frame).
A sash 1 serving as an opening / closing window according to the first embodiment shown in FIGS. 1 to 2 and 5 includes a square or rectangular sash frame 3 fixed to an opening of a window, and a window glass 2 along the sash frame 3. A surrounding shoji frame (frame) 4 is attached, and the shoji frame 4 is opened and closed via a link mechanism 5 connected to the sash frame 3.
In the present embodiment, a link mechanism 5 that opens the sash frame 4 by separating the free end side of the sash frame 4 from the sash frame 3, and connects the link mechanism 5 to the operation handle 8 to open the sash frame 4 in the opening direction by operating the operation handle 8. In the illustrated example, the sash has a sliding window structure in which the lower frame 40 of the shoji frame 4 opens from the indoor side to the outdoor side.

  In the present invention, the opening and closing of the sash is not limited to the illustrated example. included.

The sash 1 includes a square frame-shaped sash frame 3 fixed to an opening of a window, a sash frame 4 attached to the sash frame 3 so as to be openable and closable, and surrounding the window glass 2 around the periphery of the window glass 2. The sash frame 3 or a base 3 ′ integrally fixed to the sash frame 3 is provided with an operation handle 8 for opening and closing windows.
In the case of the sliding window in the illustrated example, the operation handle 8 is mounted on the lower frame 30 of the sash frame 3.

On the other hand, the sash frame 4 has an opening / closing link mechanism 5 whose tip is pivotally attached to the opening / closing frame (lower frame 40) and whose base end is pivotally attached to the lower frame 30 of the sash frame. An operating arm 6 is pivotally connected at one end to an operating arm 6, and a bolt-type rotating shaft 61 is integrally provided at a base end of the operating arm 6.
The bolt type rotation shaft 61 is rotated by the operation handle 8.

  The operation handle 8 includes a ratchet mechanism 80 that engages with the bolt-type rotation shaft 61 to rotate the rotation shaft 61 and a handle 81 that operates the ratchet mechanism 80. The rotation of the handle 81 causes the bolt-type rotation shaft to rotate. The sash 61 can be rotated in the normal rotation direction to open the sash or in the reverse rotation direction to close the sash (see FIG. 5).

In the illustrated example, the link mechanism 5 has a base end pivotally attached to the lower frame 30 of the sash frame and a distal end pivotally attached to the lower frame 40 of the shoji frame 4.
The operating arm 6 has a distal end pivotally connected to the link mechanism 5 and a proximal end operatively connected to the operating handle 8 via the bolt-type rotary shaft 61.
Accordingly, the link mechanism 5 extends or shortens the link mechanism 5 in the direction of opening and closing the sash by displacing the operating arm 6 pivoted by the operation handle 8 to move the lower frame 40 of the sash frame 4 in the outdoor or indoor direction. In parallel.

The base end of the operating arm 6 is pivotally attached to the lower frame 30 of the sash frame 3, and the pivot is the bolt-type rotary shaft 61.
In the illustrated example, the bolt-type rotation shaft 61 extends substantially vertically upward.
In the present embodiment, the upper frame 41 of the sash frame 4 is pivotally attached to the upper frame 31 of the sash frame 3 and the upper frame 40 of the sash frame 4 is a free end. When the side 41 is open, the lower frame 40 of the sash frame 4 is pivotally attached to the lower frame 30 of the sash frame 3, the upper frame 41 of the sash frame 4 is a free end, and the link mechanism 5 is the upper frame 31 of the sash frame 3. And the upper frame 41 of the shoji frame 4 (not shown).

In this case, the operation handle 8 may be mounted on the upper frame 31 of the sash frame 3 in the opposite direction. , A relay link (not shown) may be provided to transmit the movement of the operation handle 8 to the operation arm 6 by changing its direction.
Further, the link mechanism 5 only needs to correspond to the opening / closing direction of the sash frame 4 with respect to the sash frame 3, and is not limited to the parallel link mechanism, and may be a link mechanism that pivots right or left in a door manner. .

Further, the positions of the link mechanism 5 and the operation handle 8 do not need to be arranged at the same level. If the directions and heights are different, as described above, the operation handle is located between the operation arm 6 and the operation handle 8. A relay link that transmits the movement of the actuator 8 to the operating arm 6 or the link mechanism 5 by changing the height or direction may be provided.
The distal end of the operation arm 6 is connected to the link mechanism 5 so as to be interlocked therewith. In the illustrated example, the distal end of the operation arm 6 is slidably pivoted along a long hole 51 formed at an intermediate position of a predetermined link member 5 ′. ing.

As described above, the pivotal connection between the link mechanism and the operating arm in the present invention includes a case where the linking mechanism and the operating arm are pivotally connected while moving in the elongated hole.
The distal end of the link member 5 'is pivotally slidably connected to a long hole 46 of a connection fitting 45 having a long hole fixed to the sash frame 4 of the sash 4.
Thus, the pivotal movement of the operation arm 6 based on the bolt-type rotation shaft 61 can translate the lower frame 40 of the shoji frame 4 in parallel via the link member 5 'that is pivotally displaced.

The link mechanism 5 shown in FIG. 6 has a pantograph shape that intersects the operating arm 6 at an intermediate position.
In this case, similarly to the above-described embodiment, the pivotal movement of the operation arm 6 based on the bolt-type rotation shaft 61 can move the movable frame 41 of the sash 4 in parallel via the link mechanism 5.
The link mechanism 5 of the present invention only needs to be capable of displacing the free end side of the sash frame 4 of the sash 4 in the direction of opening and closing the window by parallel movement or pivotal movement, and a link using one or more known link members. A mechanism can be used.

In this embodiment, the operation handle 8 has a ratchet handle structure for operating the bolt-type rotary shaft 61 as described above.
The operation handle 8 has a drive gear integrated with an engagement receiving portion that meshes with the bolt-type rotation shaft 61 of the operation arm 6. The drive gear is supported at one or two places by a claw (claw), and has a known configuration in which the rotation direction of the drive gear is restricted in one direction and cannot be reversed, so that the description is omitted.
As an example of the ratchet mechanism 80, known structures such as Japanese Utility Model Laid-Open No. 6-666 and Japanese Patent Application Laid-Open No. 2002-307318 are known.

The operation handle 8 is provided with a known crow switching lever 8a for switching the reverse lock direction, and by switching the switching lever 8a, the direction of lock of the crow is changed, and rotation of the drive gear is changed. The direction can be switched between a normal rotation direction and a reverse rotation direction and rotated.
Here, the engagement receiving portion of the operation handle 8 and the drive gear are arranged so that the operation handle 8 rotates corresponding to the rotation direction of the bolt-type rotation shaft 61 of the operation arm 6 as described above.

With the above configuration, the user rotates the operation handle 8 in the horizontal direction about the bolt-type rotation shaft 61, thereby displacing the link mechanism 5 via the operation arm 6, and thereby moving the sash frame. 4, the sash can be opened by sliding the lower frame 40 in the outdoor direction (see FIG. 2).
As described above, the link mechanism 5 is a link mechanism that expands or contracts in the opening direction of the sash window or a link mechanism 5 that pivots, and the tip is pivotally attached to the open (free end) side frame of the shoji frame 4. The operation arm 6 pivots so as to displace the link mechanism 5 in the opening / closing direction, and is operated directly or via a transmission link relayed to a bolt-type rotation shaft 61 serving as a base axis of the operation arm 6. The handle 8 is connected.

Since the operation handle 8 has a ratchet mechanism 80 on the side that engages with the bolt-type rotary shaft 61, it is not necessary to rotate the handle 81 side by 360 degrees.
That is, the operation handle 8 can be partially rotated by an arbitrary angle in a direction to open the sash.

  Since the operation handle 8 is composed of the ratchet mechanism 80, the rotation in the direction opposite to the rotation direction of the handle 81 is not transmitted to the rotation shaft 61 and is locked. Therefore, the handle is returned and rotated in the same direction. Therefore, the rotation angle of the operation handle can be set to an arbitrary angle without being set to 360 degrees, and the sash can be opened without interference between the structure around the sash and the operation handle 8.

  Similarly, by switching the switching lever 8a in the rotation direction of the operation handle 8 and rotating the handle 81 in the reverse direction, the sash can be rotated in the reverse direction to close the sash, and the operating arm 6 pivots in the reverse direction. The window can be closed by moving the sash frame to its original position.

  Further, in the present invention, when the operation handle 8 that keeps the state by closing or opening the window is not used, the operation handle 8 is held in the posture as it is, and the sash frame 3 and the base 30 ′ are kept. For example, a concave operation handle storage unit 10 is provided at a position where the handle 8 is disposed, and can be immersed in the operation handle storage unit 10.

The operation handle storage section 10 is formed of a concave portion in which the entire operation handle 8 can be completely immersed.
That is, in the illustrated example, the operation handle storage portion 10 is formed on the lower frame 30 so that the operation handle 8 is oriented on the lower frame 30 of the sash frame 3 in a direction parallel to the lower frame 40 of the shoji frame 4. (See FIGS. 3 and 4).

That is, the operating handle 8 is provided on the lower frame 30 of the sash frame 3 so as to protrude above the lower frame 30 when used, and to be immersed in the operating handle storage unit 10 when not in use.
A cover (not shown) may be provided on the upper surface of the operation handle storage unit 10 to be urged in a direction to close the opening of the operation handle storage unit 10.
This cover may be configured to bend inward by lowering the handle when the operation handle is pushed in to open the opening of the operation handle storage section 10 and return by urging force by raising the handle to close the opening of the operation handle storage section 10.
The bolt-type rotary shaft 61 of the operating arm 6 or the operating handle 8 is preferably provided with a vertically movable mechanism.

  The retracting mechanism has a structure in which the rotary shaft 61 is disposed below the operation handle storage unit 10, and only the operation handle 8 slides up and down, and the rotary shaft 61 and the operation handle 8 slide both up and down. In other words, any structure may be used as long as the rotating shaft 61 and the operating handle 8 do not protrude above the operating handle housing 10.

For example, as shown in FIG. 7, an operating arm 6 and a rotating shaft 61 fixed to the operating arm 6 are slidable in the up and down direction, and a restricting member 7 having an operating position of the operating handle 8 as an upper limit is provided. It is attached by being urged upward by the urging means S.
In the illustrated example, the operation handle storage unit 10 includes an operation handle storage unit main body 11 that stores the handle portion of the operation handle 8, and an urging storage that is connected to the tip of the operation handle storage unit main body 11 and that is deepened in a stepped manner. And part 12.

The urging storage unit 12 stores the operating arm 6 and the rotating shaft 61 so as to be able to move up and down. Below the upper end, the upper end is hooked to the operating arm 6 or the rotating shaft 61, and the lower end of the urging storage unit 12 is closed. The biasing means S fixed to the bottom is stored.
An opening 13 is formed on one side of the biasing housing 12 so that the sliding of the operation arm 6 is not restricted.
In this case, when the operating handle 8 is pushed down from the use position shown by the solid line, the operating arm 6 is also lowered in conjunction with it, and the operating handle 8 can be stored in the recess of the storage section main body 11 of the operating handle storage section 10. it can.

In FIG. 8, the position (height) of the operation arm 6 does not change, and the bolt-type rotary shaft 61 and the operation handle 8 are integrally slid up and down.
In this case, the rotating shaft 61 is disposed in the urging housing 12 at the tip of the operation handle housing 10, and is urged upward by urging means S such as a spring.

The operation handle 8 is urged by the rotation shaft 61 in the direction of the use position.
The rotation shaft 61 has a polygonal cross section, and the operating arm 6 has a connection portion with the rotation shaft 61 as a polygonal hole that matches the cross section polygon of the rotation shaft 61, and only the rotation shaft 61 is vertically moved. And can be slidably moved only in the direction of rotation of the rotating shaft 61.
In the illustrated example, a hook 62 is formed below the rotating shaft 61, and the upper end of a spring S provided at the bottom of the urging and accommodating portion 12 is hooked on the hook to rotate the rotating shaft 61. 61 is urged upward.
As the projecting structure of the operation handle 8, other known projecting structures may be used.

It is preferable that a detachable holding means 9 for holding the operation handle 8 stored in the operation handle storage section 10 at the storage position is provided on the peripheral wall of the operation handle storage section 10.
One of the holding means 9 illustrated in FIG. 9 has a configuration in which one side has a plunger 91 embedded in the side wall of the operation handle storage section 10 and only the ball 92 at the tip slightly projects, and the other side has the operation handle 8. A substantially hemispherical concave portion 93 for engaging the ball 92 is provided at a position where the ball 92 is aligned with the ball 92 when the ball 92 is stored in the operation handle storing portion 10.

  Thus, when the operating handle 8 is pushed into the operating handle housing 10, the ball 92 of the plunger 91 is pushed into the inner side of the operating handle housing 10 by the outer peripheral surface of the lowering handle 8, and the recess 93 of the handle 8 When aligned, the urging force protrudes into and engages with the recess 93, so that the upward urging force on the operation handle 8 is suppressed and the handle 8 is locked so as not to rise.

When the handle 8 is used, the ball 92 is pushed out of the concave portion 93 and unlocked by strongly pulling the operation handle 8 upward against the urging force of the plunger 91. It rises to the use position by the upward biasing force of.
Alternatively, the bottom surface of the storage unit main body 11 is further separated from the storage position of the handle 8 further downward, so that the handle 8 at the storage position is pushed down strongly, thereby unlocking the holding means 9 from the lock, and the urging means S The structure may be such that the biasing force is increased and the repulsive force is used to automatically return to the use position.

When the handle 8 is manually pulled upward, a knob or a handle H may be provided on the upper portion of the handle 8.
The holding means 9 is provided not only in the combination of the ball of the plunger and the hemispherical concave portion but also in the operation handle storage portion 10 and is urged in the restraining direction for restraining the handle 8 from rising when the handle 8 is lowered. A constrained bar or other known means can be used.

If the engaging portion between the rotating shaft 61 and the operating handle 8 is provided with a restraining means 7 for restraining the engaging receiving portion from rising above a predetermined position, the operating handle 8 is raised by the urging force. At this time, it is possible to restrain the operation handle from rising at a predetermined position.
For example, a structure having a convex portion in which the lower end of the engagement receiving portion is engaged with the lower portion of the rotating shaft 61 may be provided.

In the above embodiment, the opening / closing link mechanism 5 and the operating arm 6 are separate bodies. However, the operating arm 6 may also serve as the opening / closing link mechanism 5, or the operating arm 6 may be a part of the opening / closing link mechanism 5. It may be configured.
In addition, the present invention is not limited to the above-described structure, that is, various design changes can be made without changing the gist of the present invention.

Next, an operation handle 8 having a different structure will be described with reference to FIG.
The operation handle 8 has a basic structure in which the aforementioned ratchet mechanism is built in, but the structure of a handle 81 serving as a grip is different.
That is, the main portion 82 of the operation handle 8 having the ratchet function remains immersed in the operation handle storage section 10 except for the handle 81.
Here, it is preferable that the main portion 82 has a substantially circular shape in plan view.
The clearance between the main part 82 and the operation handle storage part 10 may be any clearance provided that the main part 82 can rotate with the handle folded as described later.

  Further, it is preferable that the handle 81 is urged upward by an elastic member provided in the operation handle storage unit 10, and in this case, the handle 81 is pressed against the side surface of the operation handle storage unit 10 against the urging force. It is preferable to provide a stopper that is held in the operation handle storage unit 10. Therefore, it is preferable to push the rear of the handle 81 inward to release the stopper, and to push the handle 81 up onto the operation handle storage unit 10 by the urging force of the elastic member.

During operation, the handle 81 can be bent upward, for example, via a hinge between the main portion 82, and only the handle 81 protrudes from the storage portion 10.
In the illustrated example, two hinge portions are provided, the first joint portion 83 is bent at a right angle from the main portion 82, and the second joint portion 84 is bent horizontally.
In the illustrated example, each joint is bent at 90 °. However, in the present invention, the joint may be bent at an arbitrary angle that is easy to operate.

Thus, the steering wheel behind the second joint 84 can be operated.
In this embodiment, the number of joints may be one, or two or more.
In the case of the above configuration, the main portion 82 and the operating arm 6 do not need to be moved up and down, and can be operated while being maintained at a fixed position, which is convenient.

Next, the screen door 20 will be described.
As shown in FIG. 11, in the present embodiment, a mounting groove 25 for fixing the screen door 20 is provided in the lower frame 30 of the sash frame 3 inside (inside of the room) of the rail of the shoji frame 4.
The screen door 20 has a structure in which an elastic edge portion 22 made of a rubber or elastomer sealing material is fixed to a peripheral edge of a net-shaped net body 21.

The screen door 20 is fitted and fixed in a state where the elastic edge portion 22 is compressed into the mounting groove 25 for the screen door.
A proximal end of a ribbon-shaped screen door removing piece 26 is adhered to a surface of the elastic edge portion 22 of the screen door 20 on the indoor side.
Since the screen door removing piece 26 protrudes from the mounting groove 25 onto the sash frame 3 (the lower frame 30 in the illustrated example), when the screen door 20 is removed, the screen door removing piece 26 is pulled so that the elastic edge is removed. A part of the part 22 can be removed from the mounting groove 25, and the elastic door 22 can be removed from the entire periphery of the screen door 20, and the screen door 20 can be removed.

If the screen door removing piece 26 is exposed on the sash frame 3, the screen door removing piece 26 may be damaged or broken, and this is not preferable from the viewpoint of aesthetics.
Therefore, in the present invention, a removal piece storage portion 32 for storing the screen door removal piece 26 is formed in the lower frame 30 of the sash frame 3.

The detachable piece storage section 32 has a space S in the lower frame 30 for accommodating the protruding portion of the screen door remover 26, and an upper portion of the space S is opened and closed so as to be flush with the lower frame 30 when closed. It has a free outer lid piece 35.
That is, the outer lid piece 35 is connected so as not to be separated via the flexible or elastic connecting piece 36 connected to the lower frame 30, and is formed at the opening edge of the space S of the lower frame 30. The outer peripheral edge 35a of the outer lid piece 35 engages with the engaging step 33 (see FIG. 12).

In the illustrated example, the engaging step 33 has a dovetail shape, and the outer cover 35 is engaged with the engaging step 33 by strongly pushing the outer cover 35.
When the outer lid piece 35 is opened, the outer lid piece 35 is removed and pushed up from the gap 37 on the upper surface of the piece storage portion 32 to be opened, and the stored net door removal piece 26 can be used.
The engagement of the outer lid piece 36 with the detachable piece storage portion 32 and the connection portion may be replaced with a known structure.

Then, the projecting portion of the screen door removing piece 26 is stored in the space S, and the outer lid piece 35 is engaged with the engaging step 33, so that the upper surface of the lower frame 30 can be made flat. The space S may have a bottom or a bottom.
In the present embodiment, an example is shown in which the detachable piece storage section 32 is disposed in the lower frame 30 of the sash frame 3, but may be provided in one of the left and right sash frames.

Thus, even when the sash frame is provided with the detachable piece storage portion and the operation handle storage portion of the screen door, the sash frame is flat, and the sash frame is also arranged, so that the appearance of the sash can be improved.
In other words, the present invention is not limited to the above-described embodiment, and it goes without saying that various design changes can be made without changing the gist of the present invention.
