It is sectional drawing which shows the holding member in the accommodating part of a handle.

  A preferred embodiment of a handle structure of a window opening/closing device of the present invention will be described below with reference to the drawings.

The sash 1 serving as the opening/closing window of the first embodiment shown in FIGS. 1 to 2 and FIG. 5 includes a square or rectangular sash frame 3 fixed to the opening of the window, and a window glass 2 along the sash frame 3. This is a structure in which a surrounding shoji 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 for opening the shoji frame 4 by separating the free end side of the shoji frame 4 from the sash frame 3 and the link mechanism 5 connected to the operation handle 8 are operated to open in the opening direction. The sash has a structure of a sliding window in which the lower frame 40 of the shoji frame 4 opens from the indoor side to the outdoor side in the illustrated example.

  In the present invention, the opening and closing of the sash is not limited to the illustrated example, and includes a well-known sash structure such as a vertical sliding window, an outturning window, an inversion window, a raising and lowering window, an awning window, a louver window, and the like. ..

The sash 1 includes a sash frame 3 having a quadrangular frame shape fixed to an opening of a window, and a shoji frame 4 attached to the sash frame 3 so as to be openable and closable so as to surround the four circumferences of the window glass 2 and support the window glass 2. The sash frame 3 or a base portion 3′ integrally fixed to the sash frame 3 is provided with an operation handle 8 for opening and closing a window.
In the case of the sliding window of the illustrated example, the operation handle 8 is attached on the lower frame 30 of the sash frame 3.

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

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

In the illustrated example, the link mechanism 5 has its base end pivotally attached to the lower frame 30 of the sash frame and its tip pivotally attached to the lower frame 40 of the shoji frame 4.
The operation arm 6 has its tip pivotally attached to the link mechanism 5, and its base end connected to the operation handle 8 via the bolt type rotary shaft 61 so as to be interlocked.
Therefore, the link mechanism 5 expands or shortens the link mechanism 5 in the direction of opening and closing the sash by the displacement of the actuating arm 6 pivoted by the operation handle 8 to move the lower frame 40 of the shoji frame 4 to the outdoor or indoor direction. Translate towards.

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

In this case, the operation handle 8 may be attached to the upper frame 31 of the sash frame 3 in the opposite direction, but it may be attached to the lower frame 30 of the sash frame 3 or one of the left and right side frames so that the operation handle 8 and A relay link (not shown) may be provided, which is interposed between the operation arm 8 and the actuating arm 6 so as to change its direction.
The link mechanism 5 is not limited to the parallel link mechanism as long as it corresponds to the opening/closing direction of the shoji frame 4 with respect to the sash frame 3, and may be a link mechanism that pivots rightward or leftward in a door manner. ..

Further, the positions of the link mechanism 5 and the operation handle 8 do not have to be arranged at the same level, and when the orientation and the height are different, as described above, the operation handle is provided between the operation arm 6 and the operation handle 8. A relay link for transmitting the movement of 8 to the actuating arm 6 or the link mechanism 5 by changing its height or direction may be provided.
The distal end of the actuating arm 6 is linked to the link mechanism 5 in an interlocking manner, but in the illustrated example, it is slidably pivotally mounted along a long hole 51 formed at a middle position of a predetermined link member 5′. ing.

As described above, in the present invention, the pivotal attachment of the link mechanism and the actuating arm includes the case where the linkage is pivotally attached while moving in the elongated hole.
The tip end of the link member 5'is slidably attached to a long hole 46 of a connecting fitting 45 having a long hole fixed to the shoji frame 4 of the sash 4.
As a result, the pivotal movement of the actuating arm 6 with the bolt-type rotary shaft 61 as the base point can translate the lower frame 40 of the shoji frame 4 through the link member 5′ that is pivotally displaced.

The link mechanism 5 shown in FIG. 6 has a pantograph shape that intersects with the operating arm 6 at an intermediate position.
Also in this case, the pivotal movement of the actuating arm 6 based on the bolt type rotary shaft 61 can move the movable frame 41 of the sash 4 in parallel through the link mechanism 5 as in the above-described embodiment.
The link mechanism 5 of the present invention is only required to be able to displace the free end side of the shoji frame 4 of the sash 4 in the direction of opening and closing the window by parallel movement or pivoting, and a link using one or more known link members. Mechanisms can be used.

In this embodiment, the operation handle 8 has a kind of ratchet handle structure for operating the bolt type rotary shaft 61 as described above.
The operation handle 8 has an engagement receiving portion that meshes with the bolt type rotary shaft 61 of the operating arm 6 and a drive gear that is integral with the engagement receiving portion. The drive gear is supported at one or two positions by a claw (claw portion) and has a publicly known structure in which the rotation direction of the drive gear is restricted to one direction so that the drive gear cannot move backward.
Known examples of the ratchet mechanism 80 include known structures such as Japanese Utility Model Laid-Open No. 6-666 and Japanese Patent Laid-Open No. 2002-307318.
Then, as shown in FIGS. 1 to 4 and FIGS. 7 to 8, the upper end of the operation handle 8 is set to be flat.

Further, the operation handle 8 is provided with a switching lever 8a for switching a known claw for switching the reverse lock direction. By switching the switching lever 8a, the locking direction of the claw is changed to rotate the drive gear. The direction can be switched between the normal rotation direction and the reverse rotation direction for rotation.
Here, the engagement receiving portion and the drive gear of the operation handle 8 are arranged so that the operation handle 8 rotates in accordance with 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 rotary shaft 61 to displace the link mechanism 5 via the operation arm 6 and thereby the sash shoji frame. The sash can be opened by sliding the lower frame 40 of 4 in the outdoor direction (see FIG. 2).
In this way, the link mechanism 5 is a link mechanism that expands and contracts or pivots in the opening direction of the sash window, and its tip is pivotally attached to the frame of the shoji frame 4 on the open (free end) side. The actuating arm 6 pivots the link mechanism 5 so as to displace the link mechanism 5 in the opening/closing direction, and the actuating arm 6 is operated directly or via a transmission link that relays to the bolt type rotary shaft 61 serving as the pivot of the proximal end of the actuating arm 6. The handle 8 is connected.

Since the operation handle 8 has the ratchet mechanism 80 on the side that engages with the bolt type rotation 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 in an opening direction of the sash by an arbitrary angle.

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, so that the handle can be returned again and rotated in the same direction. since Bayoi, the rotational angle of the operating handle without the 360 ° corner at any angle, without the features of the sash around the operating handle 8 from interfering, as possible out to open the sash.

  Similarly, by switching the rotation direction switching lever 8a of the operation handle 8 to rotate the handle 81 in the reverse direction, the sash can be rotated in the reverse direction, and the operating arm 6 can be rotated in the reverse direction. You can move the sash's shoji frame back to its original position and close the window.

  Further, in the present invention, when the operation handle 8 for maintaining the state by closing or opening the window is not used, the operation handle 8 is kept in the posture as it is, and the sash frame 3 or the base portion 30' is used. It is possible to provide a concave storage portion 10 at the location where the handle 8 is arranged and to make the storage portion 10 immerse.

The accommodating portion 10 is composed of a recess that allows the entire operation handle 8 to be completely retracted.
That is, in the illustrated example, the storage portion 10 is formed on the lower frame 30 on the lower frame 30 of the sash frame 3 so that the operation handle 8 is oriented parallel to the lower frame 40 of the shoji frame 4. (See FIGS. 3 and 4).

That is, the lower frame 30 of the sash frame 3 is provided with the operation handle 8 that projects above the lower frame 30 when in use and can be retracted into the storage section 10 when not in use.
A cover (not shown) may be provided on the upper surface of the storage unit 10 to bias the opening of the storage unit 10.
The cover may be configured to bend inward when the operating handle is pushed down to open the opening of the storage portion 10 and to return by an urging force when the handle is raised to close the opening of the storage portion 10.
Further, it is preferable that the bolt type rotary shaft 61 of the operation arm 6 or the operation handle 8 is provided with a retracting mechanism that moves up and down.

  The retracting mechanism has a structure in which the rotary shaft 61 is arranged below the storage unit 10 and only the operation handle 8 slides up and down to project and retract, and the rotary shaft 61 and the operation handle 8 both slide up and down. Any structure, such as a protruding/withdrawing structure, that is, a structure in which neither the rotating shaft 61 nor the operation handle 8 protrudes above the storage unit 10, may be used.

For example, as shown in FIG. 7 as an example, the operating arm 6 and the rotary shaft 61 fixed to the operating arm 6 are slidable in the vertical direction, and a restraining member 7 is provided for setting the operating position of the operating handle 8 to the upper limit. And is biased upward by the biasing means S.
In the illustrated example, the storage unit 10 includes a storage unit main body 11 that stores the handle portion of the operation handle 8, and a biasing storage unit 12 that is connected to the tip of the storage unit main body 11 and that becomes deeper in a stepwise manner. There is.
The urging accommodating portion 12 accommodates the operating arm 6 and the rotary shaft 61 so as to be able to move up and down, and the lower end of the urging accommodating portion 12 is hooked on the operating arm 6 or the rotary shaft 61 and the lower end of the urging accommodating portion 12. A biasing means S fixed to the bottom is housed.
An opening 13 is formed on one side of the urging storage portion 12 so that the sliding of the operating arm 6 is not restricted.
In this case, by pushing down the operating handle 8 from the use position shown by the solid line, the operating arm 6 is also interlocked, and the operating handle 8 can be housed in the recess of the housing body 11 of the housing 10.

In FIG. 8, the position (height) of the operating arm 6 does not change, and the bolt type rotary shaft 61 and the operating handle 8 are integrally slid vertically.
In this case, the rotary shaft 61 is arranged in the biasing storage portion 12 at the tip of the storage portion 10 and is biased upward by the biasing means S such as a spring.

The operation handle 8 is biased in the use position direction by the rotating shaft 61.
The rotary shaft 61 has a polygonal cross section, and the operating arm 6 has a connecting portion with the rotary shaft 61 as a polygonal hole that matches the polygonal cross section of the rotary shaft 61. It is configured to be slidable on and to be interlocked only with the rotating direction of the rotating shaft 61.
Further, in the illustrated example, a hook portion 62 is formed below the rotary shaft 61, and the upper end of the spring S provided at the bottom of the biasing storage portion 12 is hooked on the hook portion to rotate the rotary shaft. 61 is biased upward.
As the projecting and retracting structure of the operation handle 8, other known projecting and retracting structure may be used.

In addition, it is preferable to provide a detachable holding means 9 for holding the operation handle 8 stored in the storage portion 10 at the storage position on the peripheral wall of the storage portion 10.
The holding means 9 illustrated in FIG. 9 has a structure in which one side has a plunger 91 embedded in the side wall of the storage part 10 and only the ball 92 at the tip projects slightly, and the other has the operation handle 8 stored. A substantially hemispherical recess 93 that engages the ball 92 is formed at a position aligned with the ball 92 when the ball 92 is stored in the unit 10.

  As a result, when the operation handle 8 is pushed into the storage portion 10, the ball 92 of the plunger 91 is pushed downward by the outer peripheral surface of the handle 8 into the storage portion 10 and aligns with the concave portion 93 of the handle 8. Since the protrusion 8 is engaged in the recess 93, the upward biasing 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, by pulling the operation handle 8 upward strongly against the urging force of the plunger 91, the ball 92 is pushed out from the recess 93 and the lock is released, and the operation handle 8 is urged by an urging means (not shown). The urging force of the upper part raises it to the use position.
Alternatively, the bottom surface of the storage unit main body 11 is spaced further downward from the storage position of the handle 8 so that the handle 8 in the storage position is strongly pushed downward to unlock from the holding means 9 and the biasing means S. The structure may be such that the urging force of is increased and the repulsive force automatically returns 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 housing portion 10 and restrained by the restraining direction to restrain the handle 8 from rising when the handle 8 descends. A bar or other known means can be used.

If the engagement receiving portion of the rotary shaft 61 and the operation handle 8 is provided with a restraint means 7 that restrains the engagement receiving portion from rising above a predetermined position, the operation handle 8 is raised by the urging force. At this time, the raising of the operation handle can be restrained at a predetermined position.
For example, a structure in which the lower end of the engagement receiving portion has a convex portion that engages with the lower portion of the rotating shaft 61 may be provided.

Although the opening/closing link mechanism 5 and the operating arm 6 are separate bodies in the above-described embodiment, the operating arm 6 may also serve as the opening/closing link mechanism 5, or the operating arm 6 may partially cover the opening/closing link mechanism 5. It may be configured.
Others The present invention is not limited to the above structure, and in short, various design changes can be made without changing the gist of the present invention.
