Description

  The present invention relates to a stay for use in a heat-insulated inward window in which an airtight material is provided between a window frame and a shoji that is housed inside the window frame, and more specifically, from a small-angle tilt position to a larger size. The present invention relates to a stay that can tilt the shoji to the tilted position.

  A shoji that is housed in a window frame and can be tilted to a small-angle tilt position that does not have a security problem can be tilted further to a large-angle tilt position so that the outdoor surface of the shoji can be cleaned from the indoor side. As a conventional inward window stay, the base end of an arm having a pin at the tip is pivotally attached to the middle part of the vertical frame of the window frame, and the pin at the tip of the arm is vertically moved to the side frame of the shoji. The sliding guide is slidably fitted into the long groove of the long slide guide attached so as to extend in the state that the pin occupies the upper end position of the long groove when the shoji is closed, and the shoji close to the upper end of the long slide of the long slide guide The upper part of the side frame adjacent to the upper end of the long groove extends vertically above the long groove as the upper limit of swing, and the state extending horizontally across the upper end of the long groove is set as the lower limit of swing. A pivotable pin stop lever is pivotally attached. By operating the-stop lever operation knob from the indoor side (thumb), there is tilting the sash to large angular inclination position (e.g., see Patent Document 1.).

  Further, a slider that is slidable vertically along the vertical shaft of the shoji, an arm that is pivotally connected to the slider and the vertical frame of the window frame in the indoor outside direction, and the vertical shaft of the shoji A fixed stopper that regulates the tilt angle of the shoji by the contact of the slider attached to the slider, and a movable stopper device that is attached to the vertical inner side of the shoji. The movable stopper device moves in the vertical direction. An operation member to be operated, and a movable stopper that swings between a stop position where the slider abuts and a non-stop position separated from the slider in conjunction with the vertical movement of the operation member, There is one that tilts the shoji to a large angle tilt position by operating the movable stopper from the indoor side with an operation knob (moving vertically) (for example, see Patent Document 2).

  Further, a first arm whose first end portion is connected to the vertical frame of the window frame so as to be rotatable and slidable in the vertical direction, and the first end portion is freely rotatable relative to the vertical saddle of the shoji. And a second arm whose second end is pivotally connected to the second end of the first arm, and a rotation in the same direction as the shovel tilting direction with respect to the vertical arm of the second arm. It is movable between a rotation blocking means for blocking the movement, a release position that allows the second arm to rotate in a direction opposite to the tilting direction of the shoji with respect to the vertical arm, and a fixed position that prevents this rotation. And a movable stopper is operated from the indoor side with an operation knob (moving up and down) to tilt the shoji to a large angle tilt position (see, for example, Patent Document 3). .

Utility Model Registration No. 2533301 (Fig. 1-3) JP-A-2001-279993 (FIGS. 1-3, 6-7, 9-10) Utility Model Registration No. 2550540 (Fig. 1-3)

  The conventional inward window stay configuration as described above is a configuration in which the stopper provided on the shovel of the shoji is operated from the indoor side with the operation knob, but the airtight material is provided between the window frame and the shoji. When it is going to be applied to a heat-insulating inward window provided with the above, there is a problem that it is difficult to provide the operation knob on the indoor side while ensuring airtightness. For example, in the configurations of Patent Documents 1 and 2, since it is necessary to provide an opening on the indoor side surface of the vertical frame of the shoji, it is difficult to ensure airtightness. Further, in the configuration of Patent Document 3, it is difficult to ensure airtightness because an operation knob (operation protrusion) provided on the indoor side surface side of the movable stopper is operated.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain a thermally insulated inward-turning window stay that can easily ensure airtightness. It is another object of the present invention to provide an insulated inward window stay that can secure the airtightness with a simple configuration and has high reliability in operation at a small angle tilt position or a large angle tilt position.

  In the heat-insulating inward window stay according to the present invention, opposed surfaces of the frame and the housing are formed on each of the upper and lower and left and right frames of the window frame and the upper and lower and left and right frames of the shoji, At least one of the stays used in the heat-insulating inward window provided with an airtight material that closes the gap between the opposing surfaces, and the one end of the first arm and the one end of the second arm can be rotated around a horizontal axis. And the other end of the first arm is attached to the vertical frame of the window frame so as to be rotatable about a horizontal axis and slidable in the vertical direction. Mounted so as to be rotatable about a horizontal axis with respect to the eaves, a projecting portion in the opposite direction to the other end is provided at one end of the second arm, and the second arm is in contact with the outdoor side surface of the projecting portion and the vertical arm An outward rotation restricting means for restricting rotation in the outdoor direction with respect to the kite is provided, And a movable stopper provided with an operation piece and slidably supported by the operation piece. When the movable stopper is slid upward by the operation piece, the second arm moves outward with respect to the downside. In a state where the shoji is closed, the operation piece elastically deforms the airtight member so that it can pass through the gap between the opposing surfaces of the vertical frame body and the vertical rod body. The operation piece is formed as a thin plate, extends outward in the left-right direction, and further bent in the indoor direction, so that the movable stopper can be operated from the indoor side of the shoji.

  According to the heat-insulating inward window stay according to the present invention, the opposing surfaces of the frame and the casing are formed on each of the upper and lower and left and right frames of the window frame and the upper and lower and left and right casings of the shoji. A stay used for a heat-insulating inward window provided with an airtight material that closes the gap between the opposing surfaces on at least one of the surfaces, and rotates one end of the first arm and one end of the second arm around a horizontal axis. The other end of the first arm is attached to the vertical frame of the window frame so as to be rotatable about a horizontal axis and slidable in the vertical direction, and the other end of the second arm is connected to the shoji The second arm is provided with a protrusion in the opposite direction to the other end, and is in contact with the outdoor side surface of the protrusion so that the second arm An outward rotation restricting means for restricting rotation in the outdoor direction with respect to the vertical shaft is provided, And a movable stopper provided with an operation piece. When the movable stopper is slid upward by the operation piece, the second arm is outdoors with respect to the downspout. The operation piece can elastically deform the hermetic material and pass through the gap between the opposing surfaces of the vertical frame body and the vertical frame body with the shoji screen closed. In addition, the operation piece is formed in a thin plate shape, extending outward in the left-right direction, and further bent in the indoor direction, and the operation piece enables the movable stopper to be operated from the indoor side of the shoji. With this configuration, it is possible to obtain a heat-insulating inward window stay that can secure the airtightness of the heat-insulating inward window and has good operability. In addition, high reliability in the operation of setting the small angle tilt position or the large angle tilt position over a long period of time can be ensured. Furthermore, cost reduction can be achieved. Furthermore, in the state where the heat-insulated inside-down window is closed, there is no opening or operation knob on the indoor side of the vertical frame of the shoji, and a thin operation knob between the vertical frame of the window frame and the vertical shovel of the shoji is visible. As a result, the overall appearance of the window will be a clean impression.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments shown in the accompanying drawings, and includes all the embodiments that satisfy the requirements described in the claims. It is a waste. In the present specification, the front side in the direction from the indoor side to the outdoor side is defined as the front, the rear side is defined as the rear, and the left and right are defined as the left and right toward the front. For the shoji, the direction definition is used in the most closed state. Furthermore, let the figure seen from the indoor side be a front view.

  1-3 is explanatory drawing which shows the structure of the heat insulation inversion window incorporating the stay for heat insulation inversion window which concerns on embodiment of this invention, FIG. 1 is a perspective view, FIG. 2 is a vertical left side view. FIG. 3 is a cross-sectional plan view. Moreover, FIG. 4 is explanatory drawing of the opening / closing operation | movement of a heat insulation inward window. The heat-insulating inward window 1 includes a window frame 2 and a shoji 3 that can be housed inside the window frame 2 so as to be able to fall inside. The window frame 2 includes a rectangular frame formed by combining the upper frame 21, the lower frame 22, the left vertical frame 23, and the right vertical frame 24. The shoji 3 includes an upper frame 31, a lower frame 32, and a left vertical frame. It consists of the rectangular housing | casing which combines 33 and the right vertical rod 34, the glass 5 etc. with which the window opening part 4 inside this housing is mounted | worn. A left stay 41 (described later) is provided between the left vertical frame 23 of the window frame 1 and the left vertical rod 33 of the shoji 3, and a right described later is provided between the right vertical frame 24 of the window frame 1 and the right vertical rod 34 of the shoji 3. A stay 42 is attached.

  The heat-insulating inward window 1 is formed by the rotation support portion 6 including a window frame-side support portion 7 extending in the left-right direction of the lower frame 22 and a shoji-side support portion externally fitted to the window frame-side support portion 7. The shoji 3 can be tilted indoors around the left-right direction axis of the moving support portion 6. Then, by the operation of the handle 12 shown in FIG. 2 and FIG. 4, the locking of the locking portion 14 attached to the upper frame 21 of the window frame 2 and the latching tool 12 of the latch mechanism 11 is released, and the shoji 3 is It is possible to tilt from the closed position A to the small-angle tilt position B in FIG.

  For example, when the handle 12 is raised, a force that lowers the latching tool 13 that is biased upward by a restoring force by a spring (not shown) acts, and the locking between the locking part 14 and the latching tool 13 is released, It is possible to tilt from the closed position A to the small-angle tilt position B in FIG. The shoji 3 can be tilted indoors further to the large-angle tilt position C by operating the operation piece 62 described later. In FIG. 1, illustration of the latch mechanism 11, the handle 12, and the like is omitted.

  As shown in FIGS. 2 and 4, when closing the shoji 3, if the shoji 3 is pushed forward (outdoor direction) by the handle 12 and rotated around the rotation support portion 6, the latch 13 After the inclined surface 13 a is pushed down by the locking portion 14 and passes through the locking portion 14, the latch tool 13 on which an urging force is applied rises at the closed position A and is engaged by the front surface of the locking portion 14. Stopped. Therefore, the locked state is reached at the closed position A.

  Next, the outline of the heat insulation structure of the heat-insulating inward window 1 will be described. The opposing surfaces of the frames and the casings are formed on the upper and lower frames 21 to 24 of the window frame 2 and the upper and lower frames 31 to 34 of the shoji 3, respectively. For example, the frame bodies 21 to 24 are formed with the outdoor facing surface 25 and the housings 31 to 34 are formed with the outdoor facing surface 35, and the facing surfaces 25 and 35 face each other. Moreover, the indoor side opposing surface 26 is formed in the frame bodies 21-24, and the indoor side opposing surface 36 is formed in the housings 31-34, and the opposing surfaces 26 and 36 are facing each other. And the airtight material holding | maintenance parts 27 and 29 are formed in the outdoor side opposing surface 25 and the indoor side opposing surface 26 of the frames 21-24, respectively, The outdoor side airtight material 28 and An indoor airtight material 30 is attached. Therefore, the heat insulation effect is enhanced by the double airtight structure of the outdoor side airtight material 28 and the indoor side airtight material 30. The airtight materials 28 and 30 are made of an elastic body that is easily deformed in order to improve airtightness. As materials, nitrile rubber, fluorine rubber, styrene butadiene rubber, silicone rubber, or the like is appropriately used depending on the use environment. Selected.

  Next, the configuration and operation of the heat-insulating inward window stays 41 and 42 according to the embodiment of the present invention will be described. 5-7 is explanatory drawing which shows the structure of the stay for heat insulation inversion window which concerns on embodiment of this invention, FIG. 5 is a disassembled perspective view, FIG. 6 (a) is a rear view (viewing from the outdoor side) 6 (b) is a left side view, FIG. 7 (a) is a YY sectional view of FIG. 6 (b), and FIG. 7 (b) is an XX sectional view of FIG. 6 (b). is there. Moreover, FIG. 8 is explanatory drawing which shows the state which made the movable stopper slide upwards and the rotation control to the outdoor side of the 2nd arm with respect to a vertical shaft was cancelled | released.

  In the left stay 41 and the right stay 42, the window frame mounting plate 43 and the shoji mounting plate 44 are formed vertically long in the vertical direction, and the window frame mounting plate 43 is formed on the window frame 2 using the upper and lower through holes 43a and 43a. The shoji attachment plate 44 is attached to the vertical frames 23 and 24, and the shoji attaching plate 44 is attached to the vertical rods 33 and 34 of the shoji 3 using the upper and lower through holes 44a and 44a. For example, as shown in FIG. 7A, the shoji attachment plate 44 is attached to the vertical rod 33 of the shoji 3 by the attaching screws 50 and 50 using the upper and lower through holes 44a and 44a. The window frame mounting plate 43 has a long hole 43b extending in the vertical direction between the through holes 43a and 43a, and the shoji mounting plate 44 has a through hole 44b between the through holes 44a and 44a.

  By passing the stepped rivet 48 through the through hole 51a at one end of the first arm 51 and the through hole 52a at one end of the second arm 52, the ends of the first arm 51 and the second arm 52 are connected to each other. Are coupled so as to be rotatable about a horizontal axis. A washer made of nylon or the like is mounted between the head of the stepped rivet 48 and the first arm 51 and around the shaft of the stepped rivet 48 between the first arm 51 and the second arm 52. Thus, the rotation operation around the horizontal axis is facilitated.

  By caulking the shaft end of the stepped rivet 47 through the long hole 43 b of the window frame mounting plate 43 and the through hole 51 b of the other end of the first arm 51, the other end of the first arm 51 is vertically aligned with the window frame 2. The frames 23 and 24 are attached so as to be rotatable around a horizontal axis and slidable in the vertical direction. In addition, the shaft end of the stepped rivet 49 is caulked through the through hole 52 b at the other end of the second arm 52 and the through hole 44 b of the shoji attachment plate 44, so that the other end of the second arm 52 is It is attached to the flanges 33 and 34 so as to be rotatable around a horizontal axis.

  The shoji attachment plate 44 engages with the guide groove 61 b of the movable stopper 61, and the front and rear surfaces of the guide groove 61 b come into contact with the front and rear sides of the shoji attachment plate 44. Therefore, the movable stopper 61 is restricted from moving in the front-rear direction with respect to the shoji attachment plate 44, and can be slid in the vertical direction with respect to the shoji attachment plate 44 (the vertical rods 33 and 34 of the shoji 3).

  A compression coil spring 68 is accommodated in the spring accommodating portion 67 of the movable stopper 61, and a spring receiver 45 of the shoji mounting plate 44 projects into the spring accommodating portion 67 above the compression coil spring 68. Therefore, the downward biasing force due to the restoring force of the compression coil spring 68 acts on the movable stopper 61. Further, the engagement piece 70 a of the operation piece 62 is engaged with the engagement hole 69 a of the movable stopper 61, and the engagement piece 70 b of the operation piece 62 is engaged with the engagement hole 69 b of the movable stopper 61. Since the mounting screw 66 passes through the through hole 61a and is screwed into the screw hole 62a, the movable stopper 61 and the operation piece 62 are firmly connected and integrated.

  In the vicinity of the through hole 52a at one end of the second arm 52, a protruding portion 53 is provided that protrudes in the direction opposite to the direction of the through hole 52b at the other end. In addition, the movable stopper 61 abuts against the indoor side surface 54 of the projecting portion 53 and restricts the second arm 52 from rotating in the indoor direction with respect to the vertical rods 33, 34. In addition, an outward rotation restricting means 57 is provided which abuts against the outdoor side surface 55 of the protruding portion 53 and restricts the second arm 52 from rotating in the outdoor direction with respect to the vertical rods 33 and 34. .

  Therefore, the outward rotation restricting means 57 of the movable stopper 61 contacts the outdoor side surface 55 of the protrusion 53 of the second arm 52, and the outdoor direction of the second arm 52 with respect to the vertical rods 33 and 34 (the shoji attachment plate 44). In the state where the rotation to the side is restricted (see FIG. 6), the shoji 3 tilts only to the small angle tilt position B in FIG. On the other hand, when the operation piece 62 is operated as shown in FIG. 8 and the movable stopper 61 is slid upward (refer to the arrow D in the figure), the second arm 52 has the vertical rods 33 and 34 (the shoji attachment). The shoji 3 is tilted to the large-angle tilt position C in FIG.

  Therefore, the shoji 3 of the heat-insulating inward window 1 is moved from the tilt angle to the small-angle tilt position B, which has no problem in crime prevention, to the large-angle tilt position C so that the outdoor surface of the shoji 3 can be cleaned from the indoor side. The tilt angle can be easily changed. Moreover, the arm receiver 46 is formed in the shoji attachment plate 44, and the rotation of the second arm 52 in the outdoor direction with respect to the vertical rods 33 and 34 (the shoji attachment plate 44) of the shoji 3 is restricted to a predetermined angle. Therefore, since the operation of the link mechanism in which the ends of the first arm 51 and the second arm 52 are rotatably connected can be stabilized, the opening / closing operation of the shoji 3 can be stabilized. Further, the tilt angle of the shoji 3 at the large-angle tilt position C can be adjusted by the position of the arm receiver 46. The reason why the arm receivers 46 and 46 are formed symmetrically on the shoji mounting plate 44 is that the left stay 41 and the right stay 42 share parts of the same shape.

  As shown in FIGS. 5, 6, and 8, the outdoor side surface 55 of the protrusion 53 is a substantially vertical plane, and the indoor side surface 54 of the protrusion 53 is a curved surface (substantially cylindrical surface) that is inclined forward as it goes upward. It has become. The movable stopper 61 is slidable in the vertical direction with the downward biasing force applied by the compression coil spring 68 as described above. Therefore, when the shoji 3 is returned from the large-angle tilt position C to the small-angle tilt position B in FIG. 4, the shoji 3 is pushed forward (outdoor direction) by holding the handle 12 and rotated around the rotation support portion 6. If it does, the indoor side surface 54 of the protrusion part 53 will contact | abut to the front lower part of the movable stopper 61, and this movable stopper 61 will be pushed up (for example, refer FIG. 8). When the shoji 3 reaches the small-angle tilt position B in FIG. 4, the movable stopper 61 is lowered and the outward rotation restricting means 57 is located on the outdoor side surface 55 of the protruding portion 53. The rotation of the vertical rods 33 and 34 in the outdoor direction is restricted (see FIG. 6), and this state is maintained.

  Next, the shape of the operation piece 62 of the heat-insulating inward window stays 41 and 42 according to the embodiment of the present invention will be described. The operation piece 62 is in a state in which the shoji 3 is closed (see the closed state A in FIGS. 3 and 4), and the operation piece 62 elastically deforms the indoor airtight material 30 and the vertical frames 23 and 24 and the vertical rod 33. , 34 is formed in a thin plate shape so that it can pass through the gap between the opposing surfaces 26, 36. The operation piece 62 includes an outward extending portion 63 that extends outward in the left-right direction, and an indoor-direction bent portion 64 that bends in the indoor direction after passing through the gap. Then, the locking piece 64 a of the indoor direction bending portion 64 is locked in the locking hole 65 a of the operation knob 65 that fits outside the indoor direction bending portion 64, and the operation knob 65 is attached to the operation piece 62.

  As described above, the operation piece 62 has a thin plate shape, but is firmly integrated with the movable stopper 61 as described above, and has a relatively long shape in the vertical direction. (Direction) has a shape with high rigidity and strength. Therefore, the operation for sliding the movable stopper 61 upward by the operation piece 62 can be performed stably and reliably from the indoor side. Further, as described above, the operation piece 62 elastically deforms the indoor side airtight member 30 in the state in which the shoji 3 is closed (see the closed state A in FIGS. 3 and 4) and the vertical frames 23 and 24 and the vertical frame Since it passes through the gap between the opposing surfaces 26 and 36 of the flanges 33 and 34, the airtightness of the heat-insulating inward window 1 is not impaired. Moreover, since the structure of the heat insulating inward window stays 41 and 42 including the operation piece 62 is simple, high operational reliability can be secured over a long period of time and cost reduction can be achieved.
