  The drawings show an embodiment of a screen device according to the present invention. Basically, the screen frame 1 constituting the screen device is desirably configured as a quadrilateral frame by a pair of left and right first frame members 2 and a pair of upper and lower pair of second frame members 3. . The configuration described in detail below for installation in the screen frame 1 makes it possible to easily stretch the removable screen 4 with respect to the screen frame 1 and to maintain the stretched screen 4 for maintenance and the like. Not only can it be easily removed, but it can also be installed as a simple structure, avoiding the fact that equipment and members for cleaning and replacement of the screen 4 occupy a large space around the screen device. is there. For this reason, when a screen door is fixed to a building opening frame to prevent a fall accident in a high-rise apartment, etc., it is possible to remove only the screen while the screen door frame is fixed to a sash or the like. It is effective for easy and safe cleaning.

  The configuration of the screen device will be specifically described. As shown in FIG. 1B, the screen frame 1 faces each other inside a pair of left and right first frame members 2, 2. An indented groove 6 is formed, and an inner rail 8 provided with a slit 9 along the longitudinal direction of the frame members 2, 2 is guided in the recessed groove 6. It is accommodated via the support member 10. In addition, you may comprise the said inner rail 8 as what was fixed to the supporting member 10 or integrated with it. The screen 4 stretched between the pair of first frame members 2 and 2 is slidable along the inner side of the slit 9 of the inner rail 8 on a pair of opposing sides along the left and right ends. A belt-like body 11 provided with a large number of engaging pieces 12 to be engaged with is attached, and the screen 4 is configured to be held between the left and right first frame members 2 and 2 by the large number of engaging pieces 12. ing. As the belt-like body 11 provided with a large number of engagement pieces 12, a half of a fastener widely used for clothing or the like can be used.

On the other hand, as clearly shown in FIGS. 3 and 5, the pair of upper and lower opposing sides of the screen 4 are removably held by the pair of second frame members 3 and 3 of the screen frame 1, respectively. An operating bar 15 is attached. These operating bars 15 include a rectangular tube-shaped screen connecting portion 16 that fits into a recess 18 provided on the inner end of the surface of the upper and lower second frame members 3, 3 of the screen frame 1, and the connecting portion 16. And an operation portion 17 extending from the outer surface to the outside of the recess 18.
In FIG. 3, the upper operation bar 15 is shown by a cross section at a position of a slide cover 24 described later, and the lower operation bar 15 is shown by a cross section at a position away from the slide cover 24.

  The screen connecting portion 16 is provided with slits 16a on the surface in contact with the end of the screen 4, and a band-like body 5b provided with a plurality of engaging pieces 5a that engage with the slits 16a is attached to the upper and lower ends of the screen 4, The screen 4 is made detachable by engaging the multiple engaging pieces 5a with the inner side of the slits 16a. The operation portion 17 extends outside the recess 18 to facilitate the attaching / detaching operation of the operation bar 15 to / from the recess 18, and at the same time, a protrusion 17 a provided on the outer surface by its own elastic deformation is provided in the recess 18. The operation bar 15 can be detachably fitted and locked in the recess 18 by being engaged with the inner engagement groove 18a.

  The screen 4 is assembled to the screen frame 1 in such a manner that one end side of the pair of inner rails 8 is disposed inside the slit 9 of the inner rail 8 inserted into the left and right first frame members 2 and 2 of the screen frame 1. The engagement piece 12 at the side end of the belt-like body 11 of the screen 4 is inserted, and the screen 4 is stretched over the entire length of the inner rail 8. A pair of operation bars 15 provided on the opposite sides of the screen frame 1 are fitted and locked in the recesses 18 on the surface of the second frame member 3 of the screen frame 1. Therefore, the screen 4 can be pulled out along the inner rail 8 and can be introduced into the inner rail 8 by pulling out the operating bar 15 from the recess 18 and pulling out the screen 4.

  As will be described below, in the stage where the screen 4 is stretched between the slits 9 of the inner rail 8, it is necessary that the engaging piece 12 slide smoothly with respect to the inner rail 8, and therefore, When a tensioning mechanism 40 as will be described later with reference to FIG. 1B is adopted, it is relaxed, and the pair of inner rails 8 in the left and right first frame members 2 and 2 of the screen frame 1 are It is necessary to be positioned on the mouth side of the recessed groove 6 inside the frame members 2 and 2 so that the screen 4 is held at an interval that does not give tension. In FIG. 1B, only the inner rail in the tension mechanism 40 on the left end side is depicted in a state where it is not tensioned.

  Further, in order to smoothly remove the screen 4 with the operation bars 15 attached to both ends from between the left and right first frame members 2, 2, the length of the operation bars 15 is set to the inner rail 8 inside. It is necessary to make it slightly shorter than the inner method between the pair of first frame members 2 and 2 accommodated. As can be seen from FIG. 5, when one operating bar 15 is taken out from the recess 18 and the screen 4 connected thereto is pulled out, the other operating bar 15 associated with the screen 4 is attached to the inner rail 8. It is restrained by the engagement piece 12 that engages with the slit 9 and does not largely escape from the screen frame 1, and moves between the frame members 2 and 2. When the screen 4 is introduced into the screen frame 1 along the slit 9, the screen 4 may be moved in the direction opposite to the above.

  As is apparent from the above, the operation bars 15 attached to the upper and lower ends of the screen 4 are the same in cross section, and are arranged symmetrically above and below the screen 4. By providing the shape of the recess 18 in the upper and lower frame members 3 of the screen frame 1 symmetrically, the screen frame 1 with the screen 4 stretched is adapted to the form of the sash or the like of the building opening where the screen 4 is installed. Therefore, it can be formed vertically symmetrically except for the rolling wheels attached to the lower frame member 3, the guide members attached to the upper frame member 3, and the like. 4 can be pulled out from either the upper or lower side, or can be inserted between the frame members 2 and 2 from either the upper or lower side, with the vertical direction reversed. Because the arbitrarily selected, work not only easier, it becomes possible to suppress the manufacturing cost.

  Further, the symmetrical shape enables the screen to be pulled out in either the upper or lower direction of the screen frame 1 by selecting the upper and lower operation bars 15, especially when the screen 4 is removed. The direction in which the screen 4 is led out from the screen frame 1 can be freely selected according to the installation position of the screen frame and the surrounding environment, and such a configuration is very effective for ensuring the safety of work. is there.

  In the screen device, a recess 18 is formed in each of the inner ends of the pair of upper and lower second frame members 3 and 3, and the operation beam 15 is inserted and locked, as described above. When the screen 4 is led into and out of the screen frame 1, it has a length that can pass between the pair of first frame members 2 and 2 that house the inner rail 8. When the screen 4 is introduced, as shown in FIG. 4 to FIG. 7 and FIG. 11 and the like, it is provided on the surface of the first frame member 2 on both ends of the recess 18 and on the strip 11 on the screen side end. It is necessary to provide a passage through which the engaging piece 12 is inserted into the inner rail 8 in the first frame member 2, and for this purpose, the notch 20 that forms the passage is connected to the first frame member 2. It is necessary to set up.

  In general, when the screen 4 is stretched on the screen frame 1 that is squarely framed by the pair of left and right first frame members 2 and the pair of upper and lower pair of second frame members 3, In order to remove for replacement, it is considered that a mechanism for removing the screen 4 is accommodated in the upper second frame member 3 or the like, but it is attached to the end of the screen 4 as described above. When the operation bar 15 is inserted into the recess 18 at the inner end of the surface of the second frame member 3, the first frame member 2 is communicated with the recess 18 and the notch 20 is formed. By arranging them continuously, it becomes possible to use that part as a passage for taking in and out the screen 4, and facilities and members for cleaning and replacement of the screen occupy a large space around the screen device. Can be avoided.

  Further, when the cutout portion 20 that forms the passage is provided in the first frame members 2 and 2, the passage facilitates an operation of attaching and detaching the screen 4 stretched on the screen frame 1 for maintenance or the like. In addition, a relatively difficult operation of inserting the engagement piece 12 of the band-like body 11 at the side end of the screen 4 into the narrow space in the inner rail 8 in the first frame member 2 is easy. It is necessary. For this reason, the cutout portion 20 is relatively large and may be noticeable, and the cutout portion 20 is arranged so that the screen 4 is not removed by a third party while adjusting the appearance with a simple configuration. It is desirable to cover with a cover or the like.

  From this point of view, in the screen device, as will be described below with reference to FIGS. 9 to 13, the cover to be attached to the notch 20 is used as a slide cover 24 so as not to be lost by removal. Although attached to the portion 20, the cover can be configured as an arbitrary structure that allows the cutout portion 20 to be opened and closed.

  The configuration of the slide cover 24 will be described. FIG. 11 shows a form of a notch portion 20 provided continuously at both ends of the recess 18 in the first frame member 2, and the passage is formed in the notch portion 20. Is formed. The slide cover 24 shown in FIGS. 9A to 9C is provided with a cover portion 25 that opens and closes the passage, and is cut in parallel at the cutout portion 20 of the frame member 2 as clearly shown in FIG. The slide cover 24 is guided by the guide portion 20a to open and close, and the slide cover 24 is opened by the guide portion 20a as shown in FIG. It is possible to move between the two closed positions, and the two positions can be positioned as described below.

  The configuration of the slide cover 24 will be described more specifically. First, the slide cover 24 is guided along a fixed path by a guide portion 20a formed in the cutout portion 20 of the first frame member 2. However, a sliding portion 29 is provided (see FIG. 13C). The sliding portion 29 in this embodiment is a protruding portion to the outer surface side of the bullet 27b formed by attaching a U-shaped cut 27a to the main body portion 26 of the slide cover 24 shown in FIG. 27c and the abutting piece 28 for the closed position described later. When the slide cover 24 is assembled to the cutout portion 20 of the first frame member 2, the corresponding piece 28 is formed. Since the first member 2 is also slidably contacted in many other parts, these parts also form a sliding portion.

  Further, as shown in FIG. 12, when the cover portion 25 of the slide cover 24 is slid in the open position direction with respect to the first frame member 2 by manually pressing the cover portion 25, The main body 26 of the slide cover 24 is provided with an opening position abutting piece 25a that comes into contact with the stopper portion 21 provided on the surface of the frame member 2 and stops at the opening position of the passage. As shown in FIGS. 9 and 13, the slide cover 24 is manually slid in the closed position direction so as to come into contact with the stopper portion 22 on the inner wall of the first frame member 2 and stop at the closed position of the passage. The contact part 28 for closed positions is provided. Furthermore, as shown in FIGS. 9, 12, and 13, the back surface of the cover portion 25 of the slide cover 24 is arranged on the inner surface plate 2a of the first frame member 2 that slides against the back surface. A pressing part piece 31 is provided on the side surface to apply sliding resistance to the slide cover 24 by the urging force of the elastic lever 30, and the pressing part piece 31 is configured so that the slide cover 24 can be positioned at its moving position.

  Next, the screen 4 is stretched between the slits 9 in the left and right frame members 2 and 2 in the screen frame 1, and a pair of upper and lower screens 4 are provided in a state where the screen 4 is not slackened in the vertical direction. A description will be given of a tensioning mechanism 40 for making the screen 4 stretched in the screen frame 1 tight and having a beautiful finish after the operating bar 15 is fitted and locked in the recess 18 on the surface of the screen frame 1. To do.

  The tension mechanism 40 in the screen device described above moves the inner rail 8 accommodated in the concave groove 6 of the frame member 2 in the concave and convex direction in the concave groove 6 as illustrated in FIG. Any mechanism that adjusts the degree of tension of the screen 4 may be used. For example, the inner rail 8 is supported in the recessed groove 6 in the pair of frame members 2 and 2 so as to be movable in the protruding and retracting direction. A female screw part 41 is fixed to the member 10 and can be rotated from the outside by a tool such as a screwdriver, but a male screw part 43 supported so as to be prevented from moving in the axial direction is screwed. It can be configured as an insertion.

According to the tension mechanism 40 having such a configuration, when the screen 4 is removed from the screen frame 1 or when the screen 4 is attached to the screen frame 1, the screen is simply operated by operating the male screw piece 43 with a tool such as a screwdriver. 4 is relaxed, and conversely, after the screen 4 is mounted on the screen frame 1, it is possible to moderately tension the screen by adjusting the male screw part 43 while checking the degree of tension of the screen 4. it can.
In the illustrated example, a female screw part 41 is attached to the support member 10 that supports the inner rail 8 in the recessed groove 6 of the frame member 2. However, the female screw part 41 and the male screw part piece are provided. By arranging 43 in a discrete manner in the longitudinal direction of the frame member 2, the screen can be generally uniformly tensioned.

  The present invention is not limited to the above-described embodiments, and can be implemented by changing the design without departing from the spirit of the present invention. The screen 4 is formed so as to be led out in the vertical direction along the inner rail 8 in the frame material 2, but the screen 4 is not limited to the one that is led out in the vertical direction with respect to the frame material. The frame material can be led out and inserted into the frame material, and is not limited to the case where the frame material is led in and out in both directions.
