  However, the conventional casement having such a push rod has a small opening angle of shoji. This is because when the opening angle of the shoji is increased, the angle of inclination of the protruding bar with respect to the indoor and outdoor directions also increases, and the protruding bar interferes with the vertical frame and the through hole. And, in order to prevent interference, when the found width of the through hole is increased, there is a problem that the vertical frame becomes thick and the opening area of the window becomes small.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a sash having a large opening angle and a large opening area, which has a shoji that is opened and closed by a stick.

The present invention comprises a frame, a shoji, and a push-out bar, and the shoji is pivotally supported by the frame on either the upper, lower, left, or right side, and can be opened and closed toward the outdoor side. It has an outdoor side, an intermediate part, and an indoor side, and the outdoor side is rotatably attached to the door tip side of the shoji about an axis parallel to the rotation axis of the shoji, the middle part Is rotatably connected to the outdoor side about an axis orthogonal to the rotational axis of the shoji, and the indoor side is rotatably connected to the middle part about an axis parallel to the rotational axis of the shoji There is a built-in biasing member for pressing the other along the longitudinal direction in either the indoor side portion or the middle portion, and by this biasing member, the indoor side portion is against the middle portion A guide hole which is biased to be linear and which penetrates the indoor and outdoor directions on the side of the frame opposite to the side supporting the shoji shaft. The push rod is inserted through the guide hole, and in the fully open state of the shoji, the indoor side portion of the push rod is substantially parallel to the indoor / outdoor direction, and the middle portion is positioned on the outdoor side of the frame. It is characterized in that it is bent relative to the indoor side.

  According to the present invention, by bending the push rod, the indoor side portion of the push rod becomes substantially parallel to the indoor and outdoor directions while increasing the opening angle of the shoji, thereby reducing the apparent dimensions of the guide hole and the frame. Because it can be done, the opening area of the window becomes large, and it becomes a slim design. Further, the indoor side portion operated by putting a hand operates only in a direction substantially parallel to the indoor / outdoor direction, so operability is good.

  Hereinafter, embodiments of the present invention will be described based on the drawings. As shown in FIGS. 7 and 8 (a), the sash includes a frame 1 and shoji 2 (upper shoji 2a and lower shoji 2b) connected in series. The frame 1 is formed by framing the vertical frame 11 and the horizontal frame 12 four times, and has a blind 13 at the center in the vertical direction. Then, the upper shoji 2a is placed on the upper side of the blind 13 on the inner peripheral side of the frame 1, and the lower shoji 2b is placed on the lower side of the blind 13.

  More specifically, as shown in FIG. 1 and FIG. 2, the bearing portion 21 having a substantially C-shaped cross section is formed at the left end of the upper barrier 2 a, and the outdoor side of the inner peripheral side of the vertical frame 11 on the left The shaft member 22 extending from the upper end of the vertical frame 11 to the blind 13 is screwed. The shaft member 22 has the shoji rotary shaft 23 at a position projecting to the inner peripheral side, and the bearing portion 21 of the upper shoji 2a holds in the shoji rotary shaft 23, and the bearing portion 21 with respect to the shoji rotary shaft 23 Is free to rotate. In this manner, the upper barrier 2a is rotatably supported around the vertical shutter rotational axis 23 with the left side pivotally supported by the left vertical frame 11, and is openable and closable toward the outdoor side.

  And, the upper barrier 2a is attached with the push rod 3 for performing the opening and closing operation. In addition, the description about the stick-out stick 3 of this paragraph is based on the full open state of upper shutter 2a shown in FIG.1 and FIG.3. The push rod 3 has an outdoor side portion 31, an intermediate portion 32 and an indoor side portion 33. The outdoor side portion 31 is formed by joining two L-shaped metal fittings, and has a horizontally oriented horizontal piece 311 on the outdoor side and a vertically oriented vertical piece 312 on the indoor side. Then, an L-shaped mounting bracket 24 is attached to the door tip side (the expected surface on the right side) of the upper shutter 2a, and the horizontal piece 311 of the outdoor side 31 with respect to the mounting bracket 24 is the upper shutter 2a. Mounted rotatably around a first rotational axis 34 parallel (ie perpendicular) to the rotational axis of the In addition, the middle portion 32 is formed of a rod having a rectangular cross-section, and the second end of the outdoor side end is perpendicular to the rotation axis of the upper shoji 2a (that is, horizontal) It is rotatably mounted around the rotation shaft 35. The combined length of the outdoor side portion 31 and the intermediate portion 32 is substantially the same as the lateral width of the upper shutter 2a. Further, the indoor side portion 33 is formed of a rod having a rectangular cross-section, and the outdoor side end thereof is parallel to (ie, perpendicular to) the rotation side of the upper shoji 2a with respect to the indoor side end of the intermediate portion 32. It is rotatably mounted around the three rotation shaft 36. Then, at the indoor side end of the indoor side portion 33, a knob 37 for pinching with fingers when operating the push-out bar 3 is provided. An engagement recess 38 having a U-shaped cross section is formed on the lower surface of the knob 37, and an engagement projection 39 is formed at the lower portion of the side surface of the knob 37. Yes. In addition, although the click mechanism 7 which acts so that both may become linear between the intermediate part 32 and the indoor side part 33 is provided, this is mentioned later.

  Further, in the indoor side portion of the inner peripheral side surface of the left and right vertical frames 11, a groove portion 111 having a U-shaped cross section and opening toward the indoor side is formed. Then, a guide hole 4 penetrating in the indoor and outdoor directions is provided on the bottom surface (finding surface) of the groove portion 111 of the vertical frame 11 on the right side (that is, the side opposite to the side supporting the upper shoji 2a). The rod 3 is inserted through the guide hole 4. Also, in the groove portion 111 of the vertical frame 11 on the right side, the holder 5 is housed and attached. As shown in FIGS. 1 to 4 and FIG. 8 (b), the holder 5 is a box-shaped member that opens to the indoor side, is housed within the expected width of the vertical frame 11, and the upper end is a guide hole 4 and extend downward from there, and the upper and lower lengths of the middle portion 32 and the indoor side portion 33 of the push rod 3 can be accommodated. A communication hole 51 is formed at a position overlapping with the guide hole 4 on the bottom surface (finding surface) of the holder 5 so as to pass through the indoor and outdoor directions and communicate with the guide hole 4. The communication hole 51 is inserted together with the hole 4. In addition, upper end portions (portions through which the protruding rod 3 passes in the horizontal direction) of the left and right inner side surfaces of the receiving tool 5 are formed as inclined surfaces 52 so as to be spread toward the indoor side. Further, at the lower side of the communication hole 51 on the indoor side, an engagement convex portion 53 that protrudes upward is formed. Further, an extending piece 54 is provided on the lower surface of the receiving tool 5 so as to extend upward and bending in the middle to extend to the indoor side, and the tip of the extending piece 54 projects upward. An engagement protrusion 55 is formed. A cover member 112 having a U-shaped cross section for closing the opening is inserted above and below the groove portion 111 of the left vertical frame 11 and the holder 5 of the groove portion 111 of the right vertical frame 11. Then, as shown in FIGS. 1 and 7, a fixed screen door 6 is mounted on the indoor side end of the frame 1 (the indoor side end on the inner peripheral side of the groove portion 111 in the left and right vertical frames 11). It is provided. The screen door 6 is in a series from the top to the bottom and covers the blindness 13 when viewed from the indoor side.

  As shown in FIGS. 1 and 3, in the push-out rod 3 configured in this manner, the indoor side portion 33 becomes substantially parallel to the indoor and outdoor directions in the fully open state of the upper barrier 2a, and the middle portion 32 and the outdoor side 31 Is located on the outdoor side of the frame 1 and the middle portion 32 is bent in the left direction (inner circumferential side direction) with respect to the indoor side portion 33 (a second between the outdoor side portion 31 and the middle portion 32 The rotation shaft 35 is oriented horizontally, so it does not bend here). At this time, the length of the portion of the push rod 3 located on the outdoor side of the frame 1, that is, the combined length of the outdoor side portion 31 and the intermediate portion 32 is substantially the same as the lateral width of the upper shoji 2 a. In view, a substantially equilateral triangle is formed by the lateral frame 12 of the frame 1, the upper shoji 2a, and the outdoor side portion 31 and the middle portion 32 of the stick 3. In the fully open state, by depressing the knob 37, the engagement recess 38 on the lower surface of the knob 37 engages with the engagement projection 53 of the holder 5, and the projecting rod 3 and the upper shutter 2a are fixed. Be done.

  Further, as shown in FIGS. 2 and 4, in the fully closed state of the upper shoji 2a, the portion of the push rod 3 located on the indoor side with respect to the frame 1 ie the intermediate portion 32 and the indoor side portion 33 It bends 90 degrees downward with respect to 31 and fits along the vertical frame 11 so as to fit in the holder 5 (that is, the stick 3 fits within the expected width of the vertical frame 11). Then, the engagement projection 39 of the knob 37 engages with the engagement projection 55 of the holder 5, and the push rod 3 is fixed, and the push rod 3 is bent in this way, so that the upper shutter 2a is on the indoor side. The push rod 3 functions as a locking mechanism for the upper shoji 2a.

  When the upper barrier 2a configured in this way is released from the fully closed state, the user holds the knob 37 of the push rod 3 and pulls it up to the indoor side. Under the present circumstances, although the engagement protrusion 39 of the knob part 37 is engaged with the to-be-engaged protrusion 55 of the holder 5, by applying a certain amount of force, the extension piece 54 is elastically deformed and engagement is carried out. It is released. When the middle portion 32 and the indoor side portion 33 are pulled up horizontally, the push rod 3 is pushed outward. As a result, the upper barrier 2a opens outward, and when the intermediate portion 32 passes through the guide hole 4, it starts to bend leftward with respect to the indoor side portion 33. Then, when the substantially entire length of the indoor side portion 33 is pushed until it falls within the expected width of the frame 1, the fully open state shown in FIGS. 1 and 3 is obtained. Then, the knob 37 is pushed down to engage the engagement recess 38 with the engagement projection 53 of the holder 5 to fix the upper shoji 2a in a fully open state. On the other hand, when closing from the fully open state, hold the hand on the knob portion 37 of the push rod 3 and push it up to release the engagement between the engagement concave portion 38 and the engagement convex portion 53 of the holder 5. Pull on. As a result, the upper shutter 2a closes to the indoor side, and the inclination angle of the intermediate portion 32 with respect to the indoor side portion 33 decreases. Then, when the indoor side portion 33 and the intermediate portion 32 pass through the guide hole 4, the intermediate portion 32 is bent downward with respect to the outdoor side portion 31, and the intermediate portion 32 and the indoor side portion 33 are accommodated in the holder 5. At the same time, the upper shutter 2a is drawn to the indoor side. At this time, the knob portion 37 is pushed outward, and the engagement projection 39 is engaged with the engagement projection 55 of the holder 5 to fix the upper shutter 2a in a fully closed state. A portion through which the protruding rods 3 of the left and right inner side surfaces of the receiving tool 5 pass is an inclined surface 52 so as to spread toward the indoor side, and is passing through the communication hole 51 of the guide hole 4 and the receiving tool 5 The push rod 3 can be inclined to about 10 degrees with respect to the indoor and outdoor directions, so that it is easier to push and pull.

  In the above, although the structure and operation of upper-shutter 2a were demonstrated, about lower-shutter 2b, as shown in FIG.5 and FIG.6, it is completely the same structure as upper-shutter 2a as symmetrical with upper-shutter 2a. Therefore, the opening directions of the upper-shutter 2a and the lower-shutter 2b are alternately different. As shown in FIG. 8 (a), the height position of the push rod 3 is located in the lower part of the upper shoji 2a, and in the upper part of the lower shoji 2b, both protruding rods 3 is near the vertical center of the entire sash. In this way, by arranging the both stick-out bars 3 near, it is easy to operate. Then, when both the upper and lower case 2a and 2b are fully opened, the upper frame 2a and the lower and upper window 2b are viewed from above, and the side frame 12 of the frame 1 and the upper and lower windows 2a and 2b and The outdoor side portion 31 and the middle portion 32 of the protruding bar 3 form a substantially equilateral triangle. Then, as shown in FIG. 9, the outdoor side 31a and the intermediate portion 32a of the protruding bar 3a of the upper shojia 2a are arranged almost directly above the lower shoji 2b, and the protruding bars of the lower shoji 2b are arranged side by side. The outdoor side portion 31 b and the middle portion 32 b of 3 b are located approximately directly below the upper shoji 2 a. Therefore, the sash as a whole is shaped like a regular triangular prism.

  A click mechanism 7 is provided between the middle portion 32 and the indoor side portion 33 of the push rod 3. The click mechanism 7 includes a concave surface 71 formed on the outer end surface of the indoor side portion 33, a ball 72, and a biasing member 73. The biasing member 73 is a coil spring, and is inserted into a hole 74 formed in the end face on the indoor side of the intermediate portion 32. Further, a ball 72 is inserted into the hole 74, and the biasing member 73 is a ball 72 is pressed against the concave surface 71. Since the ball 72 is normally fitted to the concave surface 71 by the click mechanism 7, the indoor side portion 33 is fixed to the middle portion 32 in a straight line. When the force is applied, the indoor side portion 33 can be inclined relative to the intermediate portion 32. However, when inclined, the concave curved surface 71 opposes the spherical body 72 against the urging force of the urging member 73 and the intermediate portion 32. As it is pushed to the side, it is always biased in the direction to make the indoor side 33 straight with respect to the middle part 32. The click mechanism 7 prevents the stick 3 from being shaken, so it is easy to operate and does not collide with the frame 1 or the like.

  According to the sash configured as described above, the bending side of the push rod 3 increases the opening angle of the shoji 2 (upper shoji 2a and lower shoji 2b) while the indoor side 33 of the push rod 3 is directed indoors and out Since the dimensions of the guide hole 4 and the frame 1 can be reduced substantially in parallel, the opening area of the window is increased, and the design is slim. Further, the indoor side portion 33 operated by putting a hand operates only in a direction substantially parallel to the indoor / outdoor direction, so the operability is good. Furthermore, since the push rod 3 is inserted through the guide hole 4 provided in the groove portion 111 of the vertical frame 11, the push rod 3 does not interfere with the screen door 6 provided on the inner peripheral side of the groove portion 111.

  Then, in the fully closed state of the upper and lower case 2a and 2b, the push rod 3 is bent along the vertical frame 11 to fit within the expected width of the vertical frame 11, and in the fully open state of the upper and lower shoji 2a and 2b. Since most of the push-out bars 3 are located on the outer side of the frame 1, the push-out bars 3 and other members do not protrude to the indoor side in any state, and pass in front of the window. It does not become an obstacle at the time. Further, since the upper and lower shutters 2a and 2b are drawn to the indoor side by the push-out rod 3 and closed, no other lock mechanism is required. Furthermore, since the push rod 3 is inserted through the guide hole 4 provided in the vertical frame 11 of the frame 1, the appearance dimension of the blind 13 between the upper shoji 2a and the lower shoji 2b can be reduced, and Since there is no handle or the like projecting to the indoor side from 13, a series of screen doors 6 in the vertical direction can be provided on the indoor side of the blind 13 to cover the blind 13 and make it a neat design. Also, in the fully open state of the upper and lower case 2a and 2b, the upper and lower cases 2a and 2b, the push rod 3, and the frame 1 form a substantially regular triangle in plan view, and these are aligned vertically. Since the sash as a whole is in the form of a regular triangular prism, the design is good. As described above, since the sash has a smart appearance in both the fully open state and the fully closed state of the upper and lower shells 2a and 2b, the sash as a whole has a good design.

  The present invention is not limited to the above embodiments. For example, as long as shoji has only one side of the upper and lower sides pivotally supported by the frame, it may have only one shoji, or a plurality of up and down or left and right may be provided in a row. . And when arranging in a row, although the opening direction of each shoji is not limited, if the opening directions of adjacent shoji are alternate as mentioned above, ventilation efficiency is good, so it is more desirable. In addition, the shapes of the shoji and the frame are shown by way of example, and any shape may be used so long as the shoji can be accommodated in the frame and open toward the outdoor side. Good. Furthermore, as for the click mechanism, contrary to the above embodiment, a concave surface may be provided in the middle portion, and a sphere and a biasing member may be provided in the indoor side.
