Left and right through holes 3a and 3b are formed. In addition, left and right through holes 2c and 2d are formed in the other end (lower end) of the frame 2, and the other ends (lower end) of the guide 3 are formed in the through holes 2c and 2d of the frame 2. Left and right through holes 3c and 3d are formed at corresponding positions. The frame 2 is fixed to a vertical frame of a window frame (not shown) using the upper and lower elongated holes 17 and 18, and a guide wall is provided on a peripheral wall that rises leftward from the periphery of the elongated hole 17 of the frame 2. 3 long holes 3g are fitted.

  The short arm 4 is made of, for example, stainless steel, and is inserted from the opening of the guide 3 so that the through hole 4a at one end thereof is aligned with the through holes 2a, 2b, 3a, 3b of the frame 2 and the guide 3, By caulking the shaft end through the stepped rivet 21 through the holes 2a, 3a, 4a, 3b, 2b, one end of the short arm 4 is connected to one end of the frame 2 so as to be rotatable about a horizontal axis. The

  The shoji mounting arm 5 is made of, for example, stainless steel, and a stepped rivet 22 is placed between the one end portion and the other end portion of the short arm 4 via a spacer 10 made of synthetic resin such as nylon or polyacetal. One end of the shoji mounting arm 5 is short armed by caulking the shaft end through the through hole 5a at one end of the mounting arm 5, the through hole 10a of the spacer 10, and the through hole 4b at the other end of the short arm 4. The other end of 4 is connected to be rotatable about a horizontal axis. Note that the shoji attachment arm 5 is fixed to the shovel of shoji (not shown) using, for example, through holes 19 and 20 formed in two places in the longitudinal direction.

  The long arm 6 is made of, for example, stainless steel, and a stepped rivet is interposed between one end of the arm 6 and the intermediate portion in the longitudinal direction of the shoji mounting arm 5 via a not-shown synthetic resin washer such as nylon or polyacetal. 23 is passed through a through-hole 6a at one end of the long arm 6 and a through-hole 5b at a middle portion in the longitudinal direction of the shoji attachment arm 5, and the end of the long arm 6 is caulked with the shoji attachment arm 5. It is connected to the middle part in the longitudinal direction so as to be rotatable around a horizontal axis.

  The long arm 6 is inserted from the opening of the guide 3 so that the through hole 6b at the other end is aligned with the through holes 2c, 2d, 3c, 3d of the frame 2 and the guide 3, and the stepped rivet 24 is inserted. By caulking the shaft end through the through holes 2c, 3c, 6b, 3d, 2d, the other end of the long arm 6 is connected to the other end of the frame 2 so as to be rotatable about a horizontal axis.

  By the planar four-bar linkage mechanism comprising the frame 2, the short arm 4, the shoji attachment arm 5 and the long arm 6 as described above, the shoji shown in FIG. 1A is fully closed, and the shoji shown in FIG. The opening and closing operation of the shoji can be performed stably and reliably between the respective states of the small open state that is opened to the extent that it is fully open and the shoji shown in FIG.

  As described above, the window stay 1 with a stopper according to the embodiment of the present invention has a simple configuration without a slider, and includes a plane four-bar linkage mechanism including a frame 2, a short arm 4, a shoji attachment arm 5, and a long arm 6. The shoji opens and closes. Therefore, since there is no slider, play does not easily occur, and a large force is not required for opening and closing the shoji. Therefore, the opening / closing operation of the shoji can be performed more stably and reliably and the high reliability of the opening / closing operation can be maintained for a long period of time. Further, as described above, the resin guide 3, spacer 10 and washer are mounted on the sliding portion and joint portion of the link of the link mechanism of the window stay 1 with a stopper, so that the opening and closing operation of the shoji is facilitated. Therefore, the reliability of the opening / closing operation of the shoji can be further improved.

  Next, the configuration and operation of the stopper mechanism will be described. 1 to 4, the slide body 7 is made of, for example, stainless steel, and is moved forward so that the vertical holes 14 are aligned with the through holes 2 e and 2 f of the frame 2 and the long holes 3 e and 3 f of the guide 3. Inserted from the opening of the guide 3 (see FIG. 4) having a substantially U-shape in plan view to be opened, the shaft end is passed through the rivet 15 through hole 2e, long hole 3e, long hole 14, long hole 3f, and through hole 2f. By caulking, the frame 2 is supported so as to be slidable in the vertical direction (in the longitudinal direction of the frame 2).

  An engaging convex portion 13 is formed on the upper portion of the slide body 7, and an operation portion 7a extending forward is formed, and a synthetic resin knob 9 is attached to the operation portion 7a. And since the spring receiving part 16 of the lower part of the slide body 7 is urged | biased upwards by the coil spring 8, the urging | biasing force is provided to the slide body 7 toward the one end part outer periphery 4c of the short arm 4. FIG. Engagement recesses 11 and 12 are formed at two locations on the outer periphery 4 c of the one end of the short arm 4.

  Therefore, when the shoji is opened from the fully closed state in FIG. 1A to the small open state in FIG. 2, the engagement convex portion 13 of the slide body 7 is formed in the engagement concave portion formed on the one end outer periphery 4 c of the short arm 4. 11, the shoji cannot be further opened from this position. In the fixed state in the small open state of the shoji, when the knob 9 is pushed down against the urging force to lower the engaging recess 13, the shoji can be opened to the fully open state in FIG. Since the engaging convex portion 13 of the body 7 engages with the engaging concave portion 12 formed on the outer periphery 4c of the one end portion of the short arm 4, the shoji is fixed at this position. In the fixed state in which the shoji is fully opened, the shoji can be closed by pushing down the knob 9 against the urging force to lower the engaging recess 13.

  In this way, the stopper is configured by engaging the engaging convex portion 13 provided on the slide body 7 with one of the engaging concave portions 11 and 12 provided at two locations on the outer periphery 4 c of the one end portion of the short arm 4. The shoji can be fixed in the small open state and the fully open state between the fully closed state and the fully open state. The stopper is configured by providing engagement convex portions at two locations on the outer periphery 4 c of the one end portion of the short arm 4 and providing an engagement concave portion that engages with the engagement convex portion of the short arm 4 on the slide body 7. May be.

  As described above, the structure of the stopper is such that the engagement protrusions 13 or 12 provided on the slide body 7 on one of the engagement recesses 11 and 12 or the engagement protrusions provided at two positions on the outer periphery 4 c of the one end of the short arm 4. Since it is a simple configuration that engages the joint recess and fixes one joint of the planar four-bar linkage mechanism, the shoji can be fixed stably and reliably, and the fixing operation has high reliability over a long period of time. Can be maintained. In addition, since the opening and closing operation and the fixing operation of the shoji are performed by the planar four-bar linkage mechanism having high rigidity and the stopper for fixing one of the joints, it is possible to more effectively suppress the play of the shoji due to wind pressure and the like. The workability at the time of cleaning the glass surface of the shoji screen performed in the fully opened state can be further improved.

  FIG. 5 is a front view showing a small open state in which the shoji is opened by about 30 ° in an example in which the window stay 1 with a stopper according to the embodiment of the present invention is used as a side sliding window in which the shoji slides indoors. Yes, the same reference numerals as those in FIGS. 1 to 4 denote the same or corresponding parts. This configuration is used by reversing the top and bottom of the window stay 1 with stopper of FIGS. 1 to 3, and even with such a configuration, the shoji can be fixed in the small open state and the full open state. 1 to 3 can be performed. Further, the release of the shoji fixed by the stopper is performed by pushing up the knob 9 against the urging force (in FIG. 5, the slide body 7 is urged downward by the coil spring 8). it can. Even if it is such a structure, there exists an effect similar to FIGS.
