Abstract

<P>PROBLEM TO BE SOLVED: To prevent the performance of packing of a vertical line from being degraded due to a sash being laterally movable by a change in the center part spacing of both vertical frames by welding an anchor when mounting an opening frame to a skeleton in a horizontal pivot window. <P>SOLUTION: In the horizontal pivot window, a bearing part 21b of a shaft seat 21 mounted to each of vertical frames 6, 6 on both sides is formed as a large diameter bearing part 21c and a small diameter bearing part 21d, and a shaft part of a shaft hinge 22 mounted to a stile 9 is formed as a large diameter shaft part 22b, a small diameter shaft part 22c and a fundamental shaft part 22d. Clearances S1, S2 are provided between the shaft part and the bearing. Consequently, even if displacement occurs between the vertical frames 6, 6 on both sides, the lateral movement of the sash is within only the clearances S1, S2, and the performance of packing is not degraded. Further, the deformation of the vertical frames is prevented and checked. <P>COPYRIGHT: (C)2011,JPO&amp;INPIT

Description

  The present invention relates to a horizontal axis rotary window. Here, the horizontal axis rotation window refers to a window in which the shoji is rotatably supported by the open frame on the horizontal axis from the middle of the vertical frame of the opening frame or from the middle to the upper side of the shoji frame.

  In order to limit the opening degree in the horizontal axis rotary window, a stopper having both ends coupled to the lower frame and the lower collar is used. This limits the opening of the shoji. Some of these stoppers incorporate a braking device.

  Recently, the rotating windows are increasing in size. For example, there is a large opening having a width of 2000 mm and a height of 1600 mm. When the shoji is supported on the horizontal axis near the center in the vertical direction of the opening, the shoji is balanced with the horizontal axis as a fulcrum. Therefore, since a rotational force is not generated from the side of the shoji when the shoji is opened and closed, it is easy to operate. However, the second moment of the shoji that rotates about the horizontal axis when opening the shoji is large. Therefore, the person who tries to open the shoji applies a great force to the shoji and accelerates the shoji. When the shoji is opened with a large force, the shoji is prevented from rotating by the stopper at the maximum opening position of the shoji, and a large force is generated in the stopper shockingly (details will be described later). This force is transmitted to the shoji and transmitted to the horizontal axis as thrust. Each of the shafts provided on the conventional bearings provided on both the flange frames and the flanges opposed to the flange frames is a single cylindrical shape, and the two surfaces provided at the base of the shaft and the surfaces facing the flanges of the bearings. A gap is provided between the end portion of the base shaft portion having a diameter larger than that of the shaft, and this mainly corresponds to the distortion of the opening frame. Therefore, the shoji can move left and right within the range of this gap. If this gap becomes large, a gap may be formed between the seal member provided on the flange frame and the flange and the mating member. Conventionally, sufficient consideration has been given to shape and size management. However, there is a case where the central part of both the frame is enlarged by welding of an anchor for attaching the opening frame to the building frame.

    None

  In the support device for the horizontal axis rotating window described in Patent Document 1, the cylindrical shaft provided on the shoji is received by the U-shaped groove provided on the saddle frame, and the shoji is movable left and right, as already described. If the middle part of the two frame is expanded, the contact of the sealing material provided on the frame with the shoji of the shoji may not be uniform on the left and right.

  In the pivot bearing in the horizontal axis rotation window described in Patent Document 2, the shoji is supported on the eaves frame by the pivot bearing on both sides of the window frame. A key member fixed on the side of the collar frame is inserted into an annular groove provided on the pivot shaft of the pivot bearing to determine the axial position of the shoji. In this way, the movement of the frame of the opening frame and the screen of the shoji is restricted in the left-right direction on the left and right sides of the window, so that it is possible to cope with an allowable manufacturing error in the enlarged horizontal axis rotation window. It is difficult and there is a high possibility that the key member cannot be inserted into both the annular grooves. Whether the key member can be inserted into the annular groove is not known unless the shoji is installed in the opening frame.

  Patent Documents 1 and 2 do not describe the relationship between supporting the shoji on the horizontal axis with respect to the opening frame and the stopper.

  Although the stopper of the horizontal axis rotation window is disclosed, there is no document that discloses the relationship between the support of the horizontal axis and the stopper.

  The present invention regulates the movement of the shoji in the left-right direction so that it can be easily assembled into the opening frame of the shoji in the horizontal direction of the rotary window with a stopper, regardless of variations in the distance between the saddle frames. Accordingly, an object of the present invention is to provide a horizontal axis rotation window in which a sealing material between a shoji fold and a heel frame acts uniformly.

The present invention provides a horizontal frame provided with a stopper that limits the opening degree of the shoji between the lower frame and the lower heel, with the eave frame and the heel intervening a sealing material and having a horizontal axis to rotatably support the shoji with respect to the opening frame. In the axis rotation window,
A mounting part that is fixed to the inner periphery of the collar frame along the collar frame, and a bearing part that projects from the mounting part toward the outer periphery of the collar, and the inner side of the collar frame is the inner side. A shaft seat having a groove opened upward in the axial restriction bearing portion on the front side in the large-diameter bearing portion, and
A mounting portion fixed to the heel along the outer periphery of the heel, a large-diameter shaft portion provided at the tip protruding from the mounting portion toward the inner periphery of the heel frame and sliding on the large-diameter bearing portion; A small-diameter shaft portion that is provided subsequent to the radial shaft portion and fits into the axial-direction regulating bearing portion, and a root shaft portion having an end surface that is close to the outer end surface of the axial-direction regulating bearing portion that is the protruding tip surface of the shaft seat. A shaft hinge that fits a large-diameter shaft portion and a small-diameter shaft portion to each bearing portion of the shaft seat,
A stopper that is secured to the shaft seat so that it can be removed from the shaft portion of the shaft hinge that is fitted in a groove that is open upward,
An extendable stopper pivotally attached to the lower arm at a position different from the position where one end is pivotally attached to the lower frame and the other end is pivotally attached to the lower frame.
The horizontal axis rotation window is characterized in that, on both sides of the frame frame and the frame, the shaft hinge limits the movement of the shaft hinge in both axial directions with respect to the shaft seat.

  According to the present invention, even if the opening frame is welded to the housing and the interval between the middle portions of the two frame frames is opened, the shoji of the horizontal axis rotating window is suddenly fully opened and an impact is generated by the stopper. Even if lateral force is applied to the shaft seat, the large-diameter shaft portion of the shaft hinge fits into the large-diameter bearing portion of the shaft seat, and the end surface of the large-diameter shaft portion and the root of the shaft hinge By restricting the axial movement of the shaft hinge by making the end face of the shaft portion approach with a gap, the movement of the shoji to the left and right is restricted, and the function of the sealing material is maintained.

  Normally, the sash is fixed (welded) to the housing with the shoji screen suspended in the opening frame, so the lateral dimensions are regulated by the shaft seat and shaft hinge, so deformation of the frame by welding is minimized. This makes it possible to reduce the mounting error.

  If the horizontal dimensions of the shoji or the opening frame are not manufactured as designed, the shoji cannot be hung on the opening frame due to the structure of the shaft hinge and shaft seat. There is an advantage of noticing.

The bearing device 3 mainly includes a shaft seat 21, a shaft hinge 22, and a retaining member 23. The right side bearing device 3 in FIG. 1 is symmetrical to the left side bearing device 3.

  The shaft seat 21 protrudes in the plane of the opening frame 1 from the mounting portion 21a to the inner periphery of the outer peripheral member 6c of the collar frame 6 along the collar frame 6 and fixed to the collar frame 6 via the pedestal 19. The bearing portion 21b is a large-diameter bearing portion 21c as viewed from the inner periphery of the collar frame 6 and the near-side axial restriction bearing portion (hereinafter referred to as a small-diameter bearing) having a smaller diameter than the large-diameter bearing portion 21c. 21d) each having a U-shaped groove 21e opened upward (see FIG. 14).

The root shaft portion 22d is chamfered on the end surface 22d1 side facing the small-diameter shaft portion 22c. The large-diameter shaft portion 22b and the small-diameter shaft portion 22c of the shaft hinge are rotatably fitted to the bearing portions 21c and 21d of the shaft seat 21, respectively.

  Here, the large-diameter bearing portion 21c has a semi-cylindrical sliding surface at the lower portion, and is a fit in which the large-diameter shaft portion 22b and the sliding surface slide together. The small-diameter bearing portion 21d only needs to have gaps between its end surfaces 21d1 and 21d2 and the end surface 22b1 of the large-diameter shaft portion 22b and the end surface 22d1 of the root shaft portion 22d as described later. The small diameter bearing portion 21d and the small diameter shaft portion 22c are loosely fitted. That is, the small-diameter bearing portion 21d only needs to have a shape that can restrict movement of the shaft portion of the shaft hinge 22 in both axial directions. Accordingly, the small-diameter bearing portion 21d has a semi-cylindrical shape in the present example. However, for example, a quarter-cylinder also functions as compared with the semi-cylindrical shape of the embodiment.

  The retaining member 23 is a retaining member that approaches the outer periphery of the large-diameter shaft portion 22 b of the shaft hinge 22 that fits into the U-shaped groove 21 e, and is detachably fixed to the shaft seat 21.

In other words, the mounting portion 21a is provided with upper and lower elongated holes 21a1 and 21a2 in the upper and lower directions, respectively, and the guide shaft 31 in which the cylindrical portion 31a just below the neck is fitted into the elongated hole 21a1 is inserted through the elongated hole 21a1 and the base 19 Screwed into. The machine screw 32 is screwed into the base 19 through the long hole 21a2.

  If this part is explained in full detail, the guide shaft 31 has the head part 31b, the cylindrical part 31a, and the thread part 31c. The axial height of the cylindrical portion 31a is slightly smaller than the thickness of the seat portion 21a4 below the concave portion 21a3 provided in the mounting portion 21a and extending in the vertical direction. The height of the head 31b is smaller than the depth of the recess 21a3. The screw part 31 c is screwed into the pedestal 19.

  The shaft seat 21 moves up and down by loosening the guide shaft 31, the locking adjustment screw 29 and the machine screw 32 and rotating the adjustment screw 25. The lowering of the shaft seat 21 is caused by a load on the shaft seat side applied from the shoji 2 through the shaft hinge 22. Thus, the vertical position, inclination, etc. of the shoji 2 with respect to the opening frame 1 are adjusted.

  The outer peripheral material 9d of the flange 9 has a protrusion 9d1 on the outer periphery. As for the axial hinge 22, the attaching part 22a contacts these protrusion 9d1 and the outer peripheral material 9d. The attachment portion 22a is fixed to the flange 9 by inserting the attachment portion 22a and screwing the small screw 33 into the back plate 34 in contact with the inside of the outer peripheral member 9d. Thereby, the shaft hinge 22 is fixed to the flange 9.

  The retainer 23 is mounted by screwing a small screw 35 inserted through the mounting portion 23 a into the mounting portion 21 a of the shaft seat 21, and the presser portion 23 b at the tip is positioned on the outer periphery of the large-diameter shaft portion 22 b of the shaft hinge 22 or with little clearance. ing.

(stopper)
FIG. 6 is a schematic plan view of the stopper. One end of the stopper 10 is pivotally attached to the lower frame 7 and the other end is pivotally attached to the lower collar 11, and can be stopped at any position where it can expand and contract. When the shoji 2 is closed, the stopper 10 has a longitudinal direction parallel to the wall surface and facing the horizontal direction.

  FIG. 7 is a side view showing a state where the stopper is attached to the lower frame 7 and the lower flange 11. The protrusion 7b on the water return 7a of the lower frame 7 is held between the frame-side bracket 41 and the L-shaped back plate 42, and a small screw 43 that passes through the back plate 42 and the protrusion 7b is screwed into the frame-side bracket 41. Thus, the frame side bracket 41 is fixed to the lower frame 7. This fixed position is close to one of the collar frames 6. A small screw 44 that passes through the back plate 42 is screwed into the lower frame 7. Here, the frame side bracket 41 and the back plate 42 are made of a stainless steel plate.

  The heel side bracket 45 abuts against the inner member 11c facing the interior of the lower ridge 11, and a machine screw 47 inserted through the heel side bracket 45 and the inner member 11c is screwed into the back plate 46 which is in contact with the back surface of the inner member 11c. A bracket 45 is fixed to the lower collar 11. Here, the heel side bracket 45 is made of zinc die cast, and the back plate 46 is made of stainless steel plate.

  8 is a front view of the stopper 10 partially shown in cross section, and FIG. 9 is a plan view of FIG. The heel side bracket 45 is connected to the rotating bracket 48. The other end of the tip shaft 59 that is caulked and fixed to the rotating bracket 48 is loosely and rotatably connected to the tip of the arm 51. The arm 51 is provided so as to move relative to the case 52 along the case 52.

  A brake device 53 that stops the movement of the arm 51 relative to the case 52 is provided at the tip of the case 52. The braking device 53 will be described. The flat and rectangular arm 51 whose cross section is thin vertically is fitted into the tip of the case 52 and fixed to the case 52 with a small screw 54, but is slidably fitted into the hole 55b of the guide plate 55.

  As shown in FIG. 8, a stopper shoe 56 is fitted between two yoke-shaped guide plates 55 so as to be movable up and down. The stopper shoe 56 is integrally provided with a stop shaft 56a so as to be in contact with the lower surface of the arm 51. The stopper shoe 56 has a stop release button 56c integrally with the upper member 56d. The arm 51 is inserted between the upper member 56d of the stopper shoe 56 and the stop shaft 56a.

  A spring seat 55a having a cylindrical recess is provided at the forked bottom of the guide plate 55. A spring 57 is contracted between the flat plate 56b to which the spring seat 55a and the stop shaft 56a are fixed. In this example, the spring 57 is a conical coil spring. The stopper shoe 56 is always biased upward by the spring force of the spring 57, and the stop shaft 56 a is always in pressure contact with the arm 51. When the stop release button 56c is pushed down against the spring force of the spring 57, the stop shaft 56a is separated from the arm 51, and the arm 51 is slidable with respect to the guide plate 55. At this time, the stopper shoe upper member 56d is in a position where it does not contact the arm 51. At this time, the lower end surface of the flat plate 56 b of the stopper shoe 56 abuts on the edge 55 c around the spring seat 55 a of the guide plate 55 so that the upper member 56 d does not contact the arm 51.

  A stop rivet 58 is provided on the base side of the arm 51 so that the arm 51 does not come out of the guide plate 55.

  With the above configuration, the braking device 53 is prevented from moving relative to the arm 51 and the case 52 by a frictional force unless the stop release button 56c is pressed. This action works regardless of the opening degree of the shoji 2, and it is prevented that the shoji 2 is closed by the external force of the wind when the shoji 2 is open.

  As shown in FIGS. 7 and 8, the base side of the stopper 10 can be tilted with respect to the frame side bracket 41 by rotating the case 52 in the horizontal plane around the base side of the case 52 and moving the tip side up and down. The frame side bracket 41 is coupled.

  That is, the body 49 a of the shaft 49 that is fitted and fixed to the frame side bracket 41 is formed into a long hole 62 a that is long in the same direction as the longitudinal direction of the case 52 of the reinforcing plate 62 that is fixed to the case 52 with the small screw 61. It is mated. The shaft 49 has a collar 49b at the end of the body 49a. A spring 63 inserted into the shaft 49 is contracted between the frame side bracket 41 and the case 52. Accordingly, the collar 49b of the shaft 49 is in pressure contact with the end face 62b of the reinforcing plate 62 just outside the elongated hole 62a. A washer 64 fixed to the frame side bracket 41 is fitted on the outer periphery of the spring 63. The washer 64 limits the amount of compression of the spring 63 and prevents the spring 63 from being offset from the shaft 49. Here, the spring 63 is a compression coil spring.

  With such a support structure of the case 52 with respect to the frame side bracket 41, the case 52 is rotatable in a horizontal plane around the shaft 49 and is tiltable in a vertical plane with respect to the position of the shaft 49. .

(Rotating bracket)
In the horizontal axis rotating window, the lower rod is tilted around a horizontal axis parallel to the wall surface, so that the lower rod and the stopper are coupled via a rotating bracket. Moreover, in order to make it easy to attach and detach the shoji to the opening frame, and to make it easy to attach and detach the stopper and the lower eyelid, the rotating bracket adopts a configuration that makes it easier to attach and detach the stopper and the lower eyelid.

  As shown in FIGS. 8 and 9, the rotating bracket 48 has a stepped cylindrical movable shaft 71 fitted in a cylindrical hole 72 b of the case 72 so as to be movable in the axial direction. The case 72 is fitted with a distal end shaft 59 coupled to the distal end of the arm 51, and is integrated with the distal end shaft 59. The axial direction of the distal end shaft 59 is perpendicular to the axial direction of the movable shaft 71, and the axial centers of the distal end shaft 59 and the movable shaft 71 intersect each other. The distal end side of the heel side bracket 45 is loosely fitted in the groove 72 a of the case 72. The front end 71a of the movable shaft 71 with a reduced diameter is fitted in the hole 45a of the bracket 45. The large-diameter piston 71b of the movable shaft 71 is fitted in the cylindrical hole 72b of the case 72 so as to be movable in the axial direction. The movable shaft 71 includes a large diameter portion piston 71b, an intermediate portion 71c having a reduced diameter, and an end small diameter portion 71d having a diameter reduced from the intermediate portion 71c.

  A keyed cap 73 having an outer diameter that is the same as that of the intermediate portion 71c of the movable shaft 71 and an inner diameter that is the same as that of the end small diameter portion 71d of the movable shaft 71 is fitted to the end small diameter portion 71d of the movable shaft 71. . As shown in FIG. 13, the cap 73 with a key groove has a hollow cylindrical shape, and as shown in FIG. 13, a circular hole 73a is provided at the center as viewed from the axial direction, and a single character groove 73b is provided as a key groove beyond the diameter of the circular hole 73a. is there. The movable shaft 71 and the key groove cap 73 are fixed by a pin 74 fitted into the hole extending over the diameter of the end small diameter portion 71 d of the key groove cap 73 and the movable shaft 71.

  The left end of the case 72 in FIG. 9 has an inner collar shape and is a spring seat 72c. Between the spring seat 72c and the piston 71b, a compression coil spring 75 is provided between the outer diameter of the intermediate portion 71c and the key groove cap 73 and the cylindrical hole 72b of the case.

  The case 72 is provided with an elongated hole 72d in the axial direction. A separation shaft 76 inserted through the elongated hole 72d in the radial direction of the case 72 is implanted in the radial direction on the outer periphery of the piston 71b of the movable shaft 71. Therefore, the movable shaft 71 is stopped from rotating with respect to the case 72, and the axial movement is restricted by the elongated hole 72d. The tip of the detachment shaft 76 protrudes out of the case 72.

  A slope cam 71e is provided at the tip 71a of the movable shaft 71. The slope cam 71e faces the direction of the inner material 11c of the lower collar 11. The inclination angle of the slope cam 71 e is 45 degrees with respect to the axial direction of the movable shaft 71. The slope cam 71e has a surface 71e1 perpendicular to the axial direction of the movable shaft 71 at the tip of the movable shaft 71. A cam follower surface portion 45b that can come into surface contact with the slope cam 71e is provided at the tip of the heel side bracket 45. The cam follower surface portion 45b has a surface 45b1 that comes into surface contact with a surface 71e1 that becomes the lift 0 portion of the inclined cam 71e at the end of the cam stroke.

  The horizontal axis rotating window is assembled by attaching the stopper 10 with the rotating bracket 48 to the lower frame 7 and mounting the shoji 2 in the opening frame 1, and the side bracket 45 and the rotating bracket 48 fixed to the lower casing 11. Are connected.

  To connect the heel side bracket 45 and the rotating bracket 48, the tip of the heel side bracket 45 is pushed into the groove 72 a of the case 72. Then, the slope cam 71e of the movable shaft 71 is pushed by the cam follower surface portion 45b at the tip of the heel side bracket 45. As the cam follower surface 45b is pushed into the groove 72a, the cam follower surface 45b and the inclined cam 71e slide relative to each other, the movable shaft 71 moves left in FIG. 9, and the compression coil spring 75 is compressed. When the cam follower surface portion 45b completely pushes the slope cam 71e, the surface 71e1 perpendicular to the axis of the lift 0 at the tip of the slope cam 71e and the end surface 45b1 of the cam follower surface portion 45b are pressed by the compression coil spring 75. The tip of the heel side bracket 45 comes into contact with the groove 72a, but the movable shaft 71 is stationary. And in the position where the cam follower surface part 45b remove | deviates from the slope cam 71e, the front-end | tip part 71a of a movable shaft exists in the position which corresponds with the hole 45a of a heel side bracket. Here, the movable shaft 71 moves rightward in FIG. 9 due to the spring force of the compression coil spring 75, the distal end portion 71a of the movable shaft is fitted into the hole 45a of the heel side bracket 45, and the heel side bracket 45 and the rotary bracket 48 are connected. Is done.

  A tool 77 shown in FIG. 13 is used to remove the heel side bracket 45 and the rotating bracket 48. In FIG. 13, only the tip of the tool 77 is shown. The tool 77 has a pin 77b that is fixedly penetrated across the tip of a handle 77a that can be inserted through the round hole 73a of the cap 73 with a key groove. The pin 77 b can pass through the one-character groove 73 b of the cap 73. The pin 77b has a larger distance between the tips than the diameter of the round hole 73a.

  The tip of the tool 77 is inserted into the cap 73 through the round hole 73a and the one-character groove 73b, and the handle 77a of the tool 77 is rotated to pull the tool 77 against the spring force of the compression coil spring 75 in FIG. The movable shaft 71 moves to the left in FIG. When the detachment shaft 76 reaches the left end of the elongated hole 72d, the end of the movable shaft 71 is located at a position retracted from the left side surface of the groove 72a of the case 72 in the drawing. In this state, the heel side bracket 45 can be removed from the groove 72 a of the case 72.

Note that when the rotary bracket 48 and the heel side bracket 45 are separated from each other by applying a force to the release shaft 76 and moving left in FIG. 9, the movable shaft 71 moves left, so that the release shaft 76 may be operated.
(Attaching the rotating window to the housing)
First, install the shoji in the opening frame, lock the shoji in the state that the shoji is closed to the opening frame, attach this rotating window to the housing, and then attach the anchor with the opening frame to the housing. Weld to members (steel).

The method for hanging the shoji 2 will be described below.
(1) A state in which the shoji 2 is parallel to the surface of the opening frame 1 and the shaft portions of the shaft hinges 22 on both sides are lifted above the U-shaped groove 21e of the shaft seat 21.
(2) The shoji 2 is slightly inclined, and the shaft portion of the shaft hinge 22 is inserted to a position above the U-shaped groove 21e of the shaft seat 21 in a state where the shoji 2 is slid into the opening frame 1.
(3) Place the shaft portion of the shaft hinge 22 on the bearing portions 21c and 21d while turning the slanting shoji 2 horizontally.

In the conventional example, the shoji can usually move in the in-plane direction at this time, but the movement in the in-plane direction is restricted because the shaft portion and the bearing portion are in two stages (details will be described later).
(4) Normally, the shaft does not move upward, but the retaining member 23 is fixed to the shaft seat 21 with the small screw 35 to complete the mounting.

  The shoji is restricted in the axial direction by the step of the large-diameter bearing and small-diameter shaft of the shaft hinge that fits the large-diameter bearing and small-diameter bearing of the shaft seat with respect to the opening frame. The airtight line can be secured without shifting in the in-plane direction.

  Normally, the sash is fixed (welded) to the housing with the shoji suspended in the opening frame, so the axial dimensions are regulated by the bearing device, so the deformation of the opening frame due to welding should be kept to a minimum. Mounting errors are less likely to occur.

  If the left and right dimensions of the shoji or the opening frame are not manufactured as designed, there is an advantage that the shoji cannot be suspended from the frame because of the structure of the bearing device, so that a manufacturing error (defect) is noticed.

(Function and effect)
The operation and effect of the above embodiment will be specifically described below.

  10, 11 and 12 are longitudinal sectional views of a conventional bearing device. 10, 11, and 12, they are omitted from illustration, although there is a retaining mechanism. FIG. 10 showing a design drawing will be described. The bearing devices 103 and 103 are left-right (L, R) symmetrical. The bearing portion 121c at the bottom of the U-shaped groove 121e of the shaft seat 121 has a semi-cylindrical shape. The shaft portion 122b of the shaft hinge 122 fitted to the bearing portion 121c is cylindrical. The clearance between the outer end surface 121c1 of the bearing 121c and the end surface 122d1 of the root shaft 122d is designed to be S3.

  After assembly, a liner 130 is inserted between the end face of the shaft portion 122b and the shaft seat 121 to limit the displacement of the shoji 2 to the left and right.

  When the rotating window having the shojis assembled in the opening frame is attached to the housing of the building, anchors are attached around the opening frame in the direction perpendicular to the frame members and the anchors are welded to the housing. Then, it deform | transforms so that the center part of the collar frames 6 and 6 may be displaced to the maximum, and the collar frames 6 and 6 will become a bow shape, and there exists a tendency for the center part of the collar frames 6 and 6 to become far.

  FIG. 11 shows the relationship between the shaft seat 121 and the shaft hinge 122 when the central portion between the collar frames 6 and 6 is far away. If the opposing distance of the center part of the collar frames 6 and 6 on both sides is increased, the left and right shaft seats 121 and 121 are far away and the opposing distance is increased. On the other hand, since there is no change in the dimension between the left and right shaft hinges 122, 122, the clearance S3 in FIG. 10 between the outer end surface 121c1 of the bearing 121c of the shaft seat 121 and the end surface 122d1 of the root shaft 122d is the clearance S4 in FIG. To become bigger. In FIG. 10, the gap S5 (<S3) between the end surface of the shaft portion 122b adjusted to a minute (for example, 0.5 millimeter) by the liner 130 and the liner 130 in FIG. 10 is as large as the gap S6 in FIG. .

If the displacement outward of the shaft seat mounting part of frame 6 is δ,
S4 = S3 + δ S6 = S5 + δ Therefore, the shoji 2 can move left and right within the opening frame 1 by 2 · S6. Therefore, in FIG. 11, the shoji 2 may be in the state shown in FIG. 12 that is offset to the left (or right). At this time, the gap S6 becomes the gap S7. The clearance S7 = 2 · S6. When the shoji 2 is displaced, the airtight packing 16 and the watertight packing 18 in FIG. 3 strongly hit one of the saddle frames 6 and 6 and weakly hit the other. As a result, the airtight packing 16 and the watertight packing 18 each have a weak airtight / watertight function on the weak side, and on the strong side, the repeated load due to the opening / closing of the shoji 2 or the early stage under a high load when the shoji 2 is not opened / closed for a long time. Causes deterioration.

  Further, in the state of FIG. 11, the bearing area between the shaft seat and the shaft hinge is reduced, so that the bearing load (intensity) per unit bearing area is increased, and there is a possibility that bearing wear is accelerated.

  In order to prevent these conditions from occurring at the site, it is necessary to insert a liner that reduces the gap S6 between the shaft portion 122b and the liner 130.

  If the shoji 2 is in the middle of the left and right in the opening frame 1 as shown in FIG. However, the shoji 2 receives a horizontal force parallel to the wall surface by the action of the stopper 10.

  FIG. 6 is a plan view for explaining the force applied to the shoji 2. In FIG. 1, the shoji 2 is fixed to the opening frame 1 so as not to rotate with respect to the opening frame 1 with a tightening handle 70 provided on the lower rod 11 in a closed state. The tightening handle 70 is released and the lower handle 11 of the shoji 2 is pushed outward by holding the tightening handle 70. At this time, the shoji 2 is opened with the stop release button 56c shown in FIG. 8 being pressed. When the stop release button 56c is pushed, the stop shaft 56a is separated from the arm 51, and the spring 57 is further compressed. As a result, the arm 51 is guided by the guide plate 55 and extends out of the case 52. At this time, the lower eyelid 11 is displaced outward and displaced upward. The distal end side of the arm 51 of the stopper 10 rises and tilts with respect to the horizontal plane. At the base of the stopper 10, the case 52 is compressed at a right angle with respect to the shaft 49, and the tilt spring 63 is biased and compressed. The rotation bracket 48 faces the left and right direction when viewed from the front and maintains the horizontal direction. At this time, the tip shaft 59 is loosely fitted to the tip of the arm 51, and this inclination is absorbed between the tip shaft 59 and the hole at the tip of the arm. On the other hand, since the inner material 11c of the lower rod 11 is inclined in the vertical direction and the lower side is inclined toward the outside, the flange 45 is inclined. Due to this inclination, the movable shaft 71 rotates relative to the hole 45a of the heel side bracket 45, and the tip shaft 59 does not tilt in the front-rear direction together with the arm 51 when viewed from the front on the inner side.

  When the shoji 2 is opened, the stop rivet 58 hits the guide plate 55. At this time, when the shoji 2 is vigorously opened, the extension of the stopper 10 between the tip of the arm 51 of the stopper 10 which is stopped from being extended by the inertia of the shoji 2 and the heel side bracket 45 via the rotary bracket 48 is shown in FIG. A force F in a direction perpendicular to the line connecting the root-side shaft 49 and the tip-side shaft 59 is generated.

  FIG. 6 is a force diagram generated in the shoji when the shoji is fully opened. FIG. 6 is a plan view schematically including the lower collar 11, the lower frame 7, and the stopper 10. Specifically, it is a plan view including a coupling portion between the stopper 10 and the frame side bracket 41 and a coupling portion between the rotating bracket 48 and the heel side bracket 45 in parallel with the lower rod 11 and the lower frame 7. The plane of this plan view is a slope whose outer side is higher than the horizontal plane. On this slope, the force F makes an angle Q with respect to the expected direction. The stopper 10 has an angle Q with a line parallel to the wall surface on the slope.

Force F is decomposed into the lateral force F ₁ direction along the force F ₂ and the wall surface toward the expected direction slightly diagonally upward is supported by a bearing device.

  Also in the conventional example, since the outer periphery of the shaft portion 122b of the shaft hinge 122 and the bearing portion 121c of the shaft seat 121 are in close contact, the shoji 2 does not move inward and outward. However, when the gap is large, such as the gap S6 between the shaft portion 122b and the liner 130 as shown in FIG. 11, the shoji 2 is shocked to the left and the gap is enlarged like the gap S7 as shown in FIG. Then, the strength of the packing between the collar frame and the collar against the mating member changes on the left and right sides of the window.

  In the embodiment of the present invention, as shown in FIGS. 4 and 5, the shaft portion of the shaft hinge 22 and the bearing portion of the shaft seat 21 are stepped in the form of a large-diameter bearing portion 21 c and a small-diameter bearing portion 21 d. The stepped shaft portions of the large-diameter shaft portion 22b and the small-diameter shaft portion 22c are fitted to the bearing portions, respectively, and an axial gap is provided between the inner end surface 21d2 of the small-diameter bearing portion 21d and the end surface 22b1 of the large-diameter shaft portion 22b. S2 (see FIGS. 4 and 5) is provided, and the base of the shaft portion of the shaft hinge 22 is expanded from the small-diameter shaft portion 22c so as to serve as the root shaft portion 22d, and the end surface 22d1 of the root shaft portion 22d and the outside of the small-diameter bearing portion 21d. An axial gap S1 is provided between the end faces 21d1.

  These gaps are provided, for example, at S1 = 1.5 millimeters and S2 = 1 millimeter. The width of the small-diameter bearing portion 21d, the opposing dimension between the outer end surface 21d1 of the small-diameter bearing portion and the end surface 22d1 of the root shaft portion 22d, the axial dimension of the outer end surface 21d1 at the tip from the mounting portion of the shaft seat 21 to the flange frame 6, The dimension from the attachment portion of the hinge 22 to the flange 9 to the end surface 22d1 of the root shaft portion 22d can be easily secured as a single component. Similarly, the accuracy between the inner end surface 21d2 of the small-diameter bearing portion 21d and the end surface 22b1 of the large-diameter shaft portion 22b can be easily ensured from the stand-alone component accuracy. A liner 30 is inserted between the shaft seat 21 and the shaft hinge 22 having such dimensions. As a result, the shoji 2 does not move to the left and right with respect to the opening frame 1.

  The above describes the case where the frame 6 is not distorted in the process of fixing the opening frame to the frame via the anchor. Assuming that the central portion of the collar frame 6 is deformed in the direction far from each other on the left and right, the shaft seat 21 moves in the axial direction with respect to the shaft hinge 22, the clearance S2 decreases, and the clearance S1 increases.

  On the left and right sides of the window, the gap S2 decreases and the gap S1 increases, but the gap S2 decreases from, for example, 1 millimeter. Therefore, if the middle parts of the collar frames 6 and 6 are far from each other, the moving amount of the shoji 2 to the left and right becomes smaller than the design value when the liner 30 is not inserted. Accordingly, the one-side gap S2 in which the movement of the shoji in the left-right direction is allowed is reduced to 1 mm or less. The designed gap S2 = 1 mm is in consideration of workability.

  Thus, according to the embodiment, even if the shoji is suddenly fully opened to generate a force for moving the shoji in the axial direction of the bearing device, the moving amount of the shoji is limited. Therefore, since the airtight packing and the watertight packing that seal the space between the frame and the lower rod are deformed almost evenly on the left and right, there is no possibility that the airtight watertightness of the window is damaged by the action based on the stopper.

  Usually, the opening frame is welded to the frame via the anchor in a state where the shoji is suspended in the opening frame. Even if the amount of deformation of the rod frame is increased due to the welding of the anchor, both the left and right bearing devices act in a direction to restrain the deformation in the wall surface of the rod frame and can suppress the deformation of the rod frame.

  The lateral movement of the shoji is restricted by the left and right bearing devices even when only one-side bearing device is used. Therefore, when the distance between the left and right shaft seats is not within the specified range, the suspension cannot be suspended when the shoji is suspended in the opening frame, so that the bearing distance is checked.
