Description

  The present invention relates to a sliding screen device attached to an indoor opening of a window sash, and more specifically, a screen is wound around a winding member provided at an upper portion between a pair of left and right guide frames. The present invention relates to an improvement of a screen device that is hung and folded in a direction along the guide frame.

  As disclosed in Patent Document 1, as an insect-proof screen door, etc., in the case of an open window that opens to the outside of the room, a sliding window, etc., it is attached to the indoor side of a window sash that does not interfere with opening and closing the shoji. Such sliding screen devices are already known. In the sliding screen device, a pair of guide frames are attached to the opening on the indoor side of the window sash in the position where the shoji is installed, and a pair of guide frames are attached to the upper part between the pair of guide frames. And a guide member guided by the guide frame at both ends in the sliding direction of the screen having a length that can be stretched around the opening. When the screen is stretched, the indoor rail (hereinafter referred to as the inner rail) is positioned at the lowest position, and when the screen is not stretched, both rails meet near the center in the length direction of the guide frame. It is formed to let you.

  In the sliding screen device described above, when the shoji side rail (hereinafter referred to as the outer rail) is moved up and down as the screen is opened and closed, the outer rail is opened and closed such as an open window (the handle shown in FIG. 3). (See 5), when the screens are set as close to the shoji as possible while avoiding interfering with each other, when the two bars are brought together near the center of the guide frame in the non-tensioned state of the screen The handle is positioned below the outer rail, and the outer rail is lowered to the guide frame that guides the raising and lowering of the outer rail so that the outer rail is lowered to the position of the handle and does not collide with the handle. A limiting stopper is provided. That is, the handle is configured to be positioned below the outer rail below the meeting position of the two rails to prevent the outer rail from colliding with it, and when opening and closing the shoji such as the outer window. The steering wheel is operated in a state where both the crosspieces are in the meeting position.

  However, in the sliding screen device, as described above, when the inner rail of the screen is moved up from the stretched state of the screen, a stopper for setting the lower limit of the outer rail that descends accordingly is provided as the length of the guide frame. The stopper must be fixed near the center in the vertical direction. The stopper can be fixed at each construction site by the length between the beam mounting portions at both ends of the screen, or by folding the screen in the direction along the guide frame. Since it is necessary to adjust the mounting position according to the mounting position of the winding member, etc., it is customary that it cannot be fixed in advance at a predetermined position in the factory, and the stopper is installed at the construction site. When attaching to the left and right guide frames, after determining the meeting position of the two rails, the left and right guide frames must be firmly fixed to the same height with screws. There is. For this reason, the manufacturing cost of the stopper itself and its mounting cost cannot be ignored, and there is a demand for lowering those costs.

The problem of the cost of mounting the stopper occurs even when there is no problem that the outer rail interferes with an opening / closing handle such as an outer window. That is, as described above, the screen is wound around the winding member, and when the screen is stretched, the inner rail is positioned at the lowest position, and when the screen is not stretched, both rails are near the central portion in the length direction of the guide frame. In the sliding screen device that is made to meet in the above, in order to keep both the bars near the central portion in the length direction of the guide frame, and to keep the opening portion where the screen is not stretched to the maximum, It is necessary to provide some kind of stopper to stably hold both the crosspieces at the meeting position.At least when moving the inner crosspiece toward the meeting position, both crosspieces should be brought to the meeting position as a feeling of the operator's hand. There is a need for a stopper-like member that communicates what has been reached.

The pair of guide frames 10 provided on the left and right sides of the opening are symmetrical to each other. A slit 13a is provided on each inner bottom of the crosspiece guide 13, which is formed by locking a flexible and highly slidable locking portion provided on both side edges of the screen 7 on the inside thereof. This prevents the both side edges from being detached from the crosspiece guide 13.

  Further, as shown in FIGS. 2 and 4, the winding member 20 for winding the screen 7 disposed on the upper part between the pair of guide frames 10 has both ends of the shoji in the window sash 2. The screen 7 is formed by a cylindrical member rotatably supported by a support member 21 attached to the frame 3, and the screen 7 wound around the winding member 20 is folded back in the direction along the guide frame 10. . As shown in FIG. 4, the support member 21 includes a receiving portion 21a of the winding member 20 formed by a circular recess, and is an introduction for dropping the winding member 20 so as to be continuous with the receiving portion 21a. A path 21b is provided. The winding member 20 is not limited to the illustrated cylindrical member, but may be a roller-shaped member, or a member fixed to the support member 21 and having a semicircular ring surface. it can.

  In the embodiment shown in FIGS. 1 to 5, when the outer frame 22 moves up and down as the screen 7 is opened and closed, the screen 7 is moved while avoiding interference with the opening / closing handle 5 such as an outer window. In order to install as close to the shoji 4 as possible, when the two bars 22 and 23 are brought together near the center of the guide frame 10 in the non-stretched state of the screen 7, In order to ensure that the handle 5 is located and to prevent the rail 22 from falling to the position of the handle 5 and colliding with the handle 5, the outer rail 22 is clearly shown in FIGS. When the inner rail 23 is moved upward from the state in which the screen 7 is stretched to reach the position where the two rails 22 and 23 meet each other near the center in the length direction of the guide frame 10, 23 is provided with a locking protrusion 25 that engages .

  As shown in FIG. 2, the outer rail 22 and the inner rail 23 include first rail members 22 a and 23 a located on the front side and second rail members 22 b and 23 b located on the rear side. Are integrated by sandwiching the end portions of the screen 7 between them and engaging a plurality of flanges provided on them with each other. The materials 22b and 23b have a common shape to reduce the manufacturing cost, and the first rail member 22a of the outer rail 22 is provided with a locking projection edge 25 made of a soft synthetic resin on the upper portion thereof by integral molding, An operation knob 23c is attached to the first crosspiece 23a of the inner crosspiece 23.

  When assembling the sliding screen device having the above-described configuration, usually, first, the outer beam 22 and the inner beam 23 are provided at both ends of the screen 7 from the upper end of the shoji-side beam guide 12 in the left and right guide frames 10 of the opening. The outer frame 22 in the screen unit to which is attached is inserted and guided, and then the winding member 20 is positioned on the lower surface side of the screen 7 and dropped into the receiving portion 21a of the support member 21 through the introduction path 21b. The crosspiece 23 is fitted into the crosspiece guide 13 on the indoor side of the guide frame 10.

  When the sliding screen device is assembled by such a procedure, the outer rail 22 having the locking protrusion 25 is positioned below the inner rail 23. Due to the presence of the locking protrusion 25, The inner rail 23 that should originally be positioned below cannot be shifted to the lower level of the outer rail 22. However, if the inner rail 23 is inserted into the rail guide 13 before the assembly, there is no need to shift the vertical position between the outer rail 22 and the inner rail 23 as long as the assembly work is not hindered. The locking protrusion 25 can be formed of a rigid or semi-rigid synthetic resin integrally with the outer rail 22.

  When assembling the sliding screen device according to the normal procedure described above, when the outer rail 22 is formed of a hard or semi-rigid synthetic resin, the locking protrusion 25 is formed of a soft synthetic resin. What is necessary is just to form integrally with the outer rail 22, and when the inner rail 23 is located higher than the outer rail 22, by pushing down the inner rail 23 strongly in the state as shown in FIG. It is possible to shift the vertical positions of the crosspieces 22 and 23 by elastic deformation of the locking protrusion 25. In this case, the locking protrusion 25 made of a soft synthetic resin is configured to be inclined or curved in a direction to be deformed when the inner rail 23 is displaced from the upper level to the lower level than the outer rail 22, and the direction By making the curve to the side easier than the curve in the opposite direction, it becomes easier to displace the inner beam 23 to the lower level of the outer beam 22, and the inner frame 23 can be moved from the stretched state of the screen 7. It is possible to suppress the inner rail 23 from reaching the upper position of the outer rail 22 as much as possible when the 23 is moved up vigorously.

  In the outer rail 22 and the inner rail 23 shown in FIG. 2, the locking projection 25 is provided only on the upper edge of the outer rail 22, but as shown in FIGS. 2 is formed by integral molding, and is engaged with the lower edge of the inner rail 23 and the lower edge of the outer rail 22 when both rails 22, 23 reach the meeting position. It is also possible to employ a configuration in which a locking protrusion 26 is provided. As described above, when the locking projections 25 and 26 are provided on the outer rail and the inner rail, as shown in FIG. 7, the engagement of the locking projections 25 and 26 and the other rail at the meeting position of both rails is achieved. , Become stronger and more secure.

The outer rail 22 and the inner rail 23 shown in FIGS. 6 and 7 have the same shape as that shown in FIG. 2, and the engagement groove 23 d provided on the lower edge of the inner rail 23 has a screen. The engaging projection 26 is integrally molded with a soft synthetic resin and fitted to the inner frame 23 together with the buffer piece 28 for buffering the inner frame 23 against the lower frame of the frame. However, the locking protrusion 26 and the buffer piece 28 can be formed integrally with the inner rail 23 as a soft synthetic resin.
6 and 7, the locking protrusion 26 that engages with the outer frame 22 is integrated with only the lower edge of the inner frame 23 without providing the locking protrusion 25 on the outer frame 22. 6 and FIG. 7, the locking protrusion 26 and the buffer piece 28 can be fitted into the engaging groove 23d.
In addition, the engagement groove 23d provided in the lower edge of the inner rail 23 can be fitted with mohair for closing the gap between the lower frame of the screen frame as required.

  Further, in the modified example of the outer rail 22 and the inner rail 23 shown in FIG. 8, the locking projection edges 25 and 26 and the buffer pieces 27 and 28 in both the rails 22 and 23 are integrated with the outer rail 22 and the inner rail 23, respectively. In addition, the bars 22 and 23 have the same shape except that a separate operation knob 30 is attached to the inner bar 23 with screws.

  In each of the outer crosspieces 22 and the inner crosspieces 23 described above, except for the case described above, the main body portions of these crosspieces are made of a hard or semi-rigid synthetic resin. The main body portion can be formed integrally or separately from the same material, or can be formed integrally or separately from the main body portion using a soft synthetic resin. Further, the locking projection edges 25 and 26 made of the above-mentioned soft synthetic resin are inclined or deformed in the direction of deformation when the inner rail 23 is displaced from the upper level to the lower level than the outer rail 22 in any modification. It is desirable to be configured to be curved so that the bending in this direction is easier than the bending in the opposite direction.

  In the sliding screen device having the above-described configuration, when the outer rail 22 and the inner rail 23 of the screen 7 are in a position where they meet each other near the center in the length direction of the guide frame 10, the inner rail 23 is moved downward. When pushed down, the screen 7 wound around the winding member 20 moves down along the crosspiece guide 13 on the indoor side of the guide frame 10, so that the screen 7 is stretched in the opening, and both crosspieces 22, 23. Stops at the upper and lower ends of the opening. When the inner rail 23 is moved up from this state, the outer rail 22 descends simultaneously with the rise of the inner rail 23, and the two rails 22, 23 meet each other in the vicinity of the central portion in the length direction of the guide frame 10, At the meeting position, the locking projections 25 and / or 26 of the outer beam 22 and / or the inner beam 23 are engaged with the other beam, the both beams stop at that position, and the screen 7 is not stretched. Held in a state.

  Thus, in the above sliding screen device, unlike the known sliding screen device, it is not necessary to attach a stopper for setting the stop position of the outer rail to a different required position for each construction site. By setting the length of the door to the minimum length required to stretch the opening, the opening when the screen is not stretched is maximized, and both the bars are engaged by the engagement of the locking protrusion and the bars. Can be stably held at the meeting position.
