FIG. 3 is a front view of the handle receiving portion 19b in the vertical rod 12 on the hanging end side, and FIGS. 4A and 4B are cross-sectional views of the metal vertical rod 19 in FIG. In FIG. 4, the thick portion of the handle receiving portion 19b shown in FIG. 2 is omitted. 2 and 4, the hollow hollow portion 32 and the hollow frame portion 33 that form a substantially rectangular tube shape extending in the vertical direction are arranged on the prospective surface 19ba side of the handle receiving portion 19b provided on the indoor side. Has been.
As shown in FIGS. 2 and 4, the hollow frame portion 33 is slidably fitted so that the substantially U-shaped slide bar 31 faces the frame portion 19c having a substantially U-shaped cross section of the metal vertical rod 19. It is configured to be hollow. A slider 34 having a substantially U-shaped cross section is fitted at a position facing the handle 30 of the slide bar 31 so as to be hollow. The slider 34 will be described later.
In the metal vertical rod 19, the hollow hollow portion 32 installed on the handle 30 side communicates with the indoor side to form an internal pressure space P filled with internal pressure, and the hollow frame portion 33 communicates with the vertical frame 5. An external pressure space Q filled with outside air is formed.

  In FIG. 4, the handle 30 includes a base portion 30 b that is bent with respect to the operation portion 30 a, and a support shaft 37 that supports the handle 30 so as to be rotatable in the vertical direction is provided on the substrate 36 provided in the hollow hollow portion 32. It is installed at the tip 30c of the base 30b. The handle 30 is pivotable in the vertical direction around the support shaft 37, and an opening 38 that allows the handle 30 to pivot is formed in the prospective surface 19ba of the handle receiving portion 19b. The opening 38 is formed in a trumpet shape, and the handle 30 can be rotated within the range of the opening 38.

The tip portion 30c formed on the handle 30 protrudes from the hollow hollow portion 32 into the hollow frame portion 33 through the insertion hole portion 19d formed in the frame portion 19c.
Further, the hollow hollow portion 32 communicates with the indoor side through an opening 38 provided in the attachment portion of the handle 30, and the upper and lower ends thereof are hermetically sealed with a seal member (not shown) or the metal upper flange 17 and the metal It is held in the internal pressure space P filled with the pressure of the indoor side air due to being in contact with the surface of the lower rod 18 or the like.

The slider 34 is slidable integrally with the slide bar 31 in the frame portion 19c, and an interlocking projection 34a having a recess for receiving the distal end portion 30c of the handle 30 is formed in a projecting manner at the center in the vertical direction. Yes. Therefore, when the handle 30 is rotated, the slider 34 moves up and down in an integrated manner with the slide bar 31 via the interlocking protrusion 34 a engaged with the tip 30 c. In addition, airtight pieces 40 for sealing the frame portion 19c are respectively attached to the upper and lower sides of the slider 34 sandwiching the tip portion 30c. The airtight pieces 40 are made of an elastic body such as sponge or rubber, for example.
Further, a Gremon lock interlocking rod (not shown) that is unlocked by the handle 30 is inserted into the hollow frame portion 33, and the slider 34 and the pair of airtight pieces 40 are connected to and integrated with the interlocking rod. Good.

The frame 19c and the hollow frame 33 provided with the slide bar 31 form an external pressure space Q, but the tip 30c of the handle 30 is inserted into the area surrounded by the slider 34, the upper and lower airtight pieces 40 and the frame 19c. An internal pressure space Pa communicating with the hollow hollow portion 32 indoors is formed through the insertion hole portion 19d. In this case, the internal pressure space Pa formed by the slider 34 does not have to be strictly an indoor air pressure, and may be an intermediate pressure between the internal pressure and the external pressure mixed with the outside air. The same applies to the internal pressure space P in the hollow hollow portion 32. Further, the internal pressure space Pa and the internal pressure space P are substantially the same pressure and are smaller than the pressure of the outside air.
Further, the upper side of the slider 34 of the metal vertical rod 19 is slidably fitted in an opening / closing cam groove 45 of a small opening restriction arm 42 described later, and is regulated as a regulating member that regulates the closing position and the opening position of the shoji 9. Pins 43 are installed.

In FIG. 5, a rotation shaft 44 is implanted in the metal vertical frame 5 a facing the frame portion 19 c of the vertical rod 12 on the hanging side, and the rotation shaft 44 is small as an opening member that regulates the opening angle of the shoji 9. The opening restricting arm 42 is rotatably supported. A spring 41 is attached to the rotary shaft 44 and the small opening restriction arm 42 to urge the small opening restriction arm 42 to a vertical position indicated by a solid line.
The small opening restricting arm 42 is formed with an opening / closing cam groove 45 into which the restricting pin 43 is fitted. The opening / closing cam groove 45 is formed, for example, in a substantially inverted Z shape. When the restricting pin 43 is located in the upper widening groove 45a, the shoji 9 is in the closed position and in the case where it is located in the lower end groove 45b. The shoji 9 is in a predetermined small opening position. The small opening restricting mechanism includes a small opening restricting arm 42 and a restricting pin 43.

  When the restricting pin 43 is positioned at the innermost end of the terminal groove 45b at the lower end of the opening / closing cam groove 45 in a state where the shoji 9 is opened at the small opening position, the shoji 9 is held in the locked state. In this state, the small opening restricting arm 42 is held obliquely as indicated by the alternate long and short dash line, so that the restricting pin 43 is held without moving from the innermost portion to the end groove 45b of the opening / closing cam groove 45. Even if the handle 30 is moved or a strong wind blows on the shoji 9, it does not shift or rotate.

4 (a) and 4 (b), between the slider 34 and the restricting pin 43 in the metal hoist 19 on the hanging end side, an operating member that can advance and retract in a direction orthogonal to the longitudinal direction of the hollow hollow portion 32. 48 is installed in the hollow hollow portion 32. The operating member 48 is located in the vicinity of the regulation pin 43. An operation pin 49 projects from the side of the operation member 48. The actuating member 48 can project outside the hollow frame portion 33 through an opening formed in the frame portion 19 c and the slide bar 31.
A release plate 50 is attached to a side portion of the operation member 48 so as to be movable up and down, and an operation pin 49 is slidably fitted in an oblique slide guide groove 50a formed in the release plate 50. In addition, a coil spring 52 is attached to the release plate 50 as an elastic member, and biases the release plate 50 upward.

  An operation lever 50b is formed on the release plate 50. The operation lever 50b protrudes from the opening groove 51 formed in the prospective surface 19ba of the handle receiving portion 19b and can be manually moved up and down. The operating lever 50b holds the operating member 48 in the retracted position at the upper end position of the opening groove 51 by the sliding guide groove 50a and the operating pin 49 (see FIG. 4A). The operating member 48 is protruded to a position where it interferes with the lower portion of the small opening restricting arm 42 at the lower end position of the opening groove 51 (see FIG. 4B).

Further, the operation lever 50b at the upper end position of the opening groove 51 is located in the vicinity of the handle 30 rotated to the upper position. Therefore, the operator can push down the operation lever 50b from the upper end position of the opening groove 51 to the lower end position while holding the handle 30 with one hand. When the operating lever 50b is at the lower end position of the opening groove 51, the operating member 48 protrudes forward, and the tip tapered portion 48a slightly pushes the lower end portion of the small opening restricting arm 42 locked at the small opening position. As a result, the regulation pin 43 moves away from the innermost part of the terminal groove 45b of the opening / closing cam groove 45 and comes out of the lock position. In this state, the shoji 9 can be closed.
The operating member 48, the operation lever 50b, the small opening restricting arm 42, etc. constitute a lock release device.

The shoji 9 is in the closed position in the lowered position of the handle 30 shown in FIG. 4A, and the shoji 9 is in the openable position in the upper position of the handle 30 shown in FIG. 4B.
Therefore, in FIG. 4A, when the handle 30 is rotated from the lowered position to the raised position shown in FIG. 4B, the distal end portion 30c of the handle 30 is rotated downward to engage the distal end portion 30c. The slider 34 moves downward integrally with the slide bar 31.

4 and 6 to 8, a substantially keyhole-shaped hole 55 is formed below the slider 34 in the slide bar 31, and a hole is formed on the back side of the hole 55 (on the prospective surface 19ba side). A trigger member 56 capable of advancing and retracting is provided at 55. The hole portion 55 is a substantially rectangular widened hole portion 55a that is close to a square on the side close to the slider 34, and a narrow groove-shaped reduced width hole portion 55b is integrally formed at the lower center thereof.
The trigger member 56 is formed with a substantially plate-like reduced-width convex portion 56a that can be fitted into the reduced-width hole portion 55b on the distal end side, and an enlarged wide-convex portion 56b that can be fitted into the enlarged-width hole portion 55a is formed integrally therewith. ing. A substantially columnar groove 57 is formed in the rear portion of the trigger member 56. Since the compressed coil spring 58 is mounted as an elastic body in the concave groove 57, the trigger member 56 is urged in a direction to fit into the hole 55 of the slide bar 31.

When the handle 30 is in the lower position, the slide bar 31 is in the upper position (reference position) shown in FIG. 4A, and the reduced-width hole 55b of the hole 55 is shown in FIG. 8A. Since it exists in the position which opposes the reduced width convex part 56a of the trigger member 56, the reduced width convex part 56a fits. When the handle 30 is rotated to the upper position shown in FIG. 4B, the slide bar 31 is lowered to the lower position. Therefore, as shown in FIG. 8 (b), the widened hole portion 55a of the hole portion 55 is located at a position facing the reduced width convex portion 56a of the trigger member 56, so that the reduced width convex portion 56a and the widened convex portion 56b are widened holes. It fits into the part 55a.
Moreover, when the widening convex portion 56b of the trigger member 56 is fitted in the widening hole portion 55a of the hole portion 55, the slide bar 31 cannot move from the lower position, so that the handle 30 is held at the upper position.

4 and 7, the metal vertical frame 5 a of the vertical frame 5 facing the hanging rod side vertical rod 12 has a trigger receiving portion 60 at a position facing the trigger member 56 installed on the metal vertical rod 19. Is fixed. The trigger receiving portion 60 is formed with a tapered surface 60 a on the surface facing the reduced width convex portion 56 a of the trigger member 56. The tapered surface 60a is inclined toward the trigger member 56 so that the wall thickness gradually increases from the outdoor side toward the indoor side.
Therefore, as shown in FIG. 8B, the shoji 9 is placed in the state in which the widening convex portion 56 b of the trigger member 56 is fitted in the widening hole 55 a of the hole 55 of the slide bar 31 at the open position of the shoji 9. When the closing operation is performed in the direction of arrow A, the reduced-width convex portion 56a comes into contact with the tapered surface 60a of the trigger receiving portion 60 and gradually retreats so that the widened convex portion 56b is detached from the wide-width hole portion 55a. It becomes movable.
Note that. The hole 55 formed in the slide bar 31 provided in the vertical rod 12, the trigger member 56, and the trigger receiving portion 60 provided in the vertical frame 5 constitute a locking device.

As shown in FIGS. 4 and 10, the regulation pin 43 is held in a substantially bottomed cylindrical holding frame 63, and the bottom of the regulation pin 43 is formed as a regulation pin adjusting portion 64 on the prospective surface 19ba of the handle receiving portion 19b. Exposed. The restriction pin adjusting portion 64 is formed with a fitting groove 64a that is thin and extends in the front-rear direction. A key member 65 shown in FIG. 9 can be inserted into the fitting groove 64a. The key member 65 includes a diameter-enlarged key portion 65a and a support portion 65b that is formed on the base end side thereof and has a stepped diameter.
Further, the holding frame 63 shown in FIG. 10 has a substantially cylindrical shape, and the base portion of the regulation pin 43 has an enlarged columnar main body portion 43b via a small diameter portion 43a, and the main body portion 43b is formed of the holding frame 63. It is inserted in the inside so as to be able to advance and retreat. The base part of the main body part 43b is attached to an advance / retreat part 67 attached to the regulating pin adjustment part 64, and the advance / retreat part 67 is rotatable about 90 degrees, for example, with respect to the main body part 43b. A coil spring 68 as a biasing means is mounted in a compressed state between the advance / retreat receiving portion 67 and the regulation pin adjusting portion 64, and the advance / retreat receiving portion 67 is rotatable by, for example, approximately 90 degrees.

  A shaft body 69 fitted in a narrow groove 63 a formed to face the inner surface of the holding frame 63 is mounted in the main body portion 43 b of the restriction pin 43, and a through hole parallel to the shaft body 69 is provided behind the shaft body 69. 70 and a receiving surface 70a are formed. The restriction pin 43 is guided by the shaft body 69 and the groove portion 63a with respect to the holding frame 63 so as to be linearly movable back and forth. Further, the fitting groove 64a formed in the regulation pin adjusting portion 64 communicates with the through hole 70 through the receiving surface 70a.

Then, after inserting the diameter-enlarged key portion 65a of the key member 65 into the fitting groove 64a from the regulation pin adjusting portion 64, the key member 65 is rotated 90 degrees within the through hole 70 as shown in FIG. . Then, the advance / retreat receiving portion 67 rotates together with the key member 65, but the receiving surface 70a of the main body portion 43b does not rotate. Therefore, the fitting groove 64a is displaced by approximately 90 degrees between the receiving surface 70a and the advance / retreat receiving portion 67.
When the key member 65 is retracted, the diameter-enlarged key portion 65a comes into contact with the receiving surface 70a of the through hole 70, and the restriction pin 43 including the main body portion 43b is drawn into the holding frame 63 side. The arm 42 is disengaged from the opening / closing cam groove 45. In this state, the shoji 9 can be opened to an arbitrary angle, for example, 90 degrees beyond a predetermined angle of the small opening.

Further, when the key pin 65 is released from the retracted position where the restricting pin 43 is out of the opening / closing cam groove 45, the restricting pin 43 protrudes forward together with the forward / backward receiving portion 67 by the biasing force of the coil spring 68 and is inserted into the opening / closing cam groove 45. Will be. In order to reinsert the regulating pin 43 into the opening / closing cam groove 45, it is preferable to return the shoji 9 to the small opening position of a predetermined angle or to return the shoji 9 to the closed position.
Such key member 65, advance / retreat receiving portion 67, fitting groove 64a, holding frame 63, restricting pin 43, small opening restricting arm 42, and the like constitute an engaging / disengaging device.

The vertical window 1 according to the present embodiment has the above-described configuration, and the operation thereof will be described next.
As shown in FIG. 4A, the handle 30 is positioned below in the state in which the shoji 9 is closed, and the slide bar 31 is in the upper position (reference position). Therefore, as shown in FIG. 8A, the reduced width convex portion 56a of the trigger member 56 is fitted by the biasing force of the coil spring 58 into the lower width reduced hole portion 55b on the lower side of the hole portion 55, and the widened convex portion 56b. It has stopped. In this state, the small opening restricting arm 42 hangs down to a closed position indicated by a solid line in FIG.

From this state, the handle 30 is rotated upward to open the shoji 9 as shown in FIG. Then, the interlocking rod of the handle 30 moves backward from the upper frame 3 and the lower frame 4 and is pushed by the distal end portion 30c to interlock the slider 34 downward, and moves to the lower position integrally with the slide bar 31. As a result, as shown in FIG. 8B, the hole 55 descends along the reduced width convex portion 56a of the trigger member 56, and the reduced width convex portion 56a reaches the position of the widened hole portion 55a. Therefore, the trigger member 56 moves forward by the urging force of the coil spring 58, and the widening convex portion 56b is fitted into the widening hole portion 55a.
As a result, the slide bar 31 is fixedly held at the lower position, and the handle 30 is also fixedly held at the upper position shown in FIG.

  Then, when the shoji 9 is opened, as shown in FIG. 5, the small opening restricting arm 42 is pushed around the rotating shaft 44 while sliding along the opening / closing cam groove 45 by the restricting pin 43 provided on the shoji 9. The shoji 9 is opened to the small opening position. In the small opening position, the restriction pin 43 is locked at the innermost part of the terminal groove 45 b below the opening / closing cam groove 45. The shoji 9 is held at this small opening position and cannot return to the closing direction.

Next, in order to close the shoji 9, the handle 30 is grasped with one hand and the operation lever 50 b of the release plate 50 is lowered downward within the opening groove 51 with the finger of the hand. As the release plate 50 is lowered, the operating pin 49 moves along the sliding guide groove 50a to cause the operating member 48 to protrude. Then, as shown in FIG. 5, the operating member 48 moves the small opening restricting arm 42 from the one-dot chain line position to the unlocked two-dot chain line position by pushing the lower end of the small opening restricting arm 42, The restriction pin 43 is shifted from the innermost end portion of the end groove portion 45 b of the opening / closing cam groove 45.
As a result, the regulating pin 43 is disengaged from the locking position of the opening / closing cam groove 45, and the shoji 9 can be closed. Since the handle 30 is locked by the trigger member 56 and the hole 55, the interlocking rod is held in the retracted state during the opening / closing operation of the shoji 9.

When the shoji 9 is closed and reaches the vicinity of the vertical frame 5 of the frame body 7, the trigger member 56 protruding from the hole 55 of the slide bar 31 is a trigger receiver in which the widening protrusion 56b at the tip is provided on the metal vertical frame 5a. It abuts on the tapered surface 60 a of the portion 60. When the shoji 9 is further operated to close, the trigger member 56 pushed by the tapered surface 60 a moves backward against the urging force of the coil spring 58, and the widened convex portion 56 b is disengaged from the widened hole portion 55 a of the hole portion 55 to lock. The shoji 9 reaches the closed position.
As a result, the slide bar 31 is raised by rotating the handle 30 downward from the raised position, and the interlocking bar protrudes in the vertical direction and is locked to the upper frame 3 and the lower frame 4. Thus, the shoji 9 can be opened and closed.

Next, in order to clean the shoji 9 or the like, it is further opened from the small opening position and opened, for example, at an angle of 90 degrees. Therefore, as shown in FIG. 10A, the key member 65 is inserted into the fitting groove 64a of the restriction pin adjusting portion 64 provided on the prospective surface 19ba of the handle receiving portion 19b for the shoji 9 at the small opening position. To do.
After the diameter-enlarged key portion 65a of the key member 65 abuts against the inner wall of the through hole 70 of the main body portion 43b, the key member 65 is moved 90 degrees together with the advance / retreat portion 67 in the fitting groove 64a as shown in FIG. Rotate. In this case, since the main body 43b does not rotate, the angle of the fitting groove 64a differs between the receiving surface 70a and the advance / retreat receiving portion 67 by approximately 90 degrees.

  When the key member 65 is pulled in the pulling direction, the diameter-enlarged key portion 65 a comes into contact with the receiving surface 70 a of the through hole 70 and pulls the main body portion 43 b against the biasing force of the coil spring 68. As a result, as shown in FIG. 10C, the restriction pin 43 having the main body 43 b is also pulled in and is released from the opening / closing cam groove 45 of the small opening restriction arm 42. In this state, the shoji 9 can be further opened from the small opening position. Then, the shoji 9 is opened 90 degrees, for example, and the frame 7 and shoji 9 are cleaned.

  When the shoji 9 is returned to the small opening position after the cleaning or the like is finished and the key member 65 is released, the restricting pin 43 returns to the original position by the biasing force of the coil spring 68, and the restricting pin 43 is placed in the opening / closing cam groove 45. Inserted. Thereafter, the key member 65 can be pulled out from the fitting groove 64a by rotating it 90 degrees, returning it to the original position, and pulling it out (see FIG. 4A).

As described above, according to the vertical extending window 1 according to the present embodiment, the handle 30 and the operation lever 50b are located close to each other with the shoji 9 opened by a predetermined opening with a small opening, so that the operator has only one hand. The operating lever 50b can be operated while gripping the handle 30. Therefore, the operating lever 50 b can be operated with one hand to release the small opening restricting arm 42 from the locked position with the restricting pin 43 and the shoji 9 can be closed with the handle 30.
Further, the actuating member 48 pushes the lower portion of the small opening restricting arm 42 separated from the rotating shaft 44 in the vicinity of the restricting pin 43 held in the innermost part of the opening / closing cam groove 45 of the small opening restricting arm 42 to restrict the opening. The pin 43 can be released from the locked position. Therefore, since the force required for the operation of the small opening restricting arm 42 is small, the lock can be easily released.

Further, by attaching the key member 65 to the holding frame 63 and rotating and pulling it out, the regulating pin 43 can be detached from the opening / closing cam groove 45, and the shoji 9 can be opened more greatly. Moreover, by releasing the key member 65, the urging force of the coil spring 68 can return the restriction pin 43 to the position where it is engaged in the opening / closing cam groove 45, and the engagement / disengagement operation between the opening / closing cam groove 45 and the restriction pin 43 is achieved. Is easy. In addition, by using the key member 65, the person who performs the engagement / disengagement operation of the restriction pin 43 from the opening / closing cam groove 45 can be restricted.
In addition, since the engagement / disengagement between the regulating pin 43 and the opening / closing cam groove 45 can be switched by the key member 65, the key member 65 can be easily managed by restricting the person who operates the key member 65.
