  1 to 7 show an embodiment of a screen device according to the present invention. This screen device basically has a screen 4 stretched on a quadrangular frame 1 or when the stretched screen 4 is removed from the screen frame 1 for maintenance or the like. In addition to facilitating operation, the screen 4 can be easily held in tension after being stretched. Especially in high-rise condominiums and the like, a screen door is used to prevent falling accidents. For example, when the screen door is fixed to the sash or the like, the screen is removed while the screen door frame is fixed to the sash or the like, so that the screen can be replaced and washed easily and safely.

  The configuration of the screen device will be described in detail. The screen frame 1 has a rectangular shape with a pair of upper and lower frame members 2 and 2 and a pair of left and right frame members 3 and 3 for stretching a screen 4 such as an insect screen. In the frame, grooves 6 are respectively formed in the facing portions inside the pair of left and right frame members 3, 3, and slits along the longitudinal direction of the frame members 3, 3 are formed in the groove 6. The inner rail 8 provided with 9 is accommodated in the concave groove 6 via a support member 10 that is guided to move in the protruding and retracting direction. In addition, you may comprise the said inner rail 8 as what was fixed to the supporting member 10 or integrated with it. Further, the screen 4 stretched between the pair of frame members 3 and 3 has a large number of engaging pieces 12 which are slidably engaged along the inner side of the slit 9 along the left and right ends thereof. And the engagement piece 12 is engaged with the inside of the slit 9 of the inner rail 8 so that the screen 4 is held between the left and right frame members 3 and 3. As the engaging piece 12, a half of a fastener can be used.

  On the other hand, as clearly shown in FIGS. 3 and 5, operation bars 15 that are detachably held by the screen frame 1 are attached to a pair of upper and lower opposing sides of the screen 4. These operating bars 15 are formed in a rectangular tube-shaped screen connecting portion 16 fitted into a recess 18 provided at the inner end of the surface of the upper and lower frame members 2, 2 of the screen frame 1, and recessed from the outer surface of the connecting portion 16. And an operation portion 17 extending to the outside of the place 18. The screen connecting portion 16 is provided with slits 16a on the surface in contact with the end portion of the screen 4, and a large number of engaging portion pieces 4a attached to the upper and lower ends of the screen 4 are engaged with the inside of the screen 4 so that the screen 4 The operating portion 17 extends to the outside of the recess 18 to facilitate the attaching / detaching operation of the operating bar 15 to the recess 18, and at the same time, elastically deforms itself on the outer surface. The provided protrusion 17a can be engaged with the engagement groove 18a in the recess 18 so that the operation bar 15 can be detachably fitted into the recess 18.

  The screen 4 is assembled to the screen frame 1 from the one end side of the pair of inner rails 8 inside the slits 9 of the inner rails 8 inserted into the left and right frame members 3, 3 of the screen frame 1. A pair of operations provided on the upper and lower opposing sides of the screen 4 in a state where the screen 4 is stretched over the entire length of the inner rail 8 and the screen 4 is not slackened in the vertical direction. This is done by inserting and locking the bar 15 into the recess 18 on the surface of the screen frame 1.

  As described in detail below, in the stage where the screen 4 is stretched between the slits 9 of the inner rail 8, the sliding of the engaging piece 12 with respect to the inner rail 8 needs to be smooth, Therefore, as will be described later with reference to FIG. 2, the tensioning mechanism is relaxed, and the pair of inner rails 8 in the left and right frame members 3, 3 of the screen frame 1 is maintained at an interval that does not apply tension to the screen 4. Thus, it is necessary to be positioned on the mouth side of the recessed groove 6 inside the frame members 3 and 3 (see FIG. 1).

  Further, in order to smoothly remove the screen 4 with the operation bars 15 attached to both ends from between the left and right frame members 3, 3, the length of the operation bars 15 is set inside the inner rail 8 in the screen frame 1. It may be shorter than the inner method between the pair of opposing frame members 3 and 3 accommodated in the housing. As can be seen from FIG. 5, one operating bar 15 is taken out from the recess 18 and connected thereto. When the screen 4 is pulled out, the other operating bar 15 associated with the screen 4 is not restrained by the engagement piece 12 engaged with the slit 9 of the inner rail 8 and largely escapes from the screen frame 1. The left and right frame members 3 and 3 are moved. 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 description with reference to FIGS. 3 to 5, the operation bars 15 attached to the upper and lower ends of the screen 4 have the same cross-sectional shape, and are symmetrical with respect to the top and bottom of the screen 4. Therefore, the shape of the recess 18 in the upper and lower frame members 2 of the screen frame 1 is also provided symmetrically, and as a result, the screen frame 1 on which the screen 4 is stretched is installed. Except for the rolling wheel 19a attached to the lower frame member 2 and the guide member 10b attached to the upper frame member 2 in order to adapt to the form of the sash or the like of the opening of the building, it can be formed symmetrically vertically. it can. 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 configuration in which 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, the surrounding environment, etc. is very effective for ensuring the safety of work. Is.

  Next, the screen 4 is stretched between the slits 9 in the left and right frame members 3, 3 in the screen frame 1, and a pair of the screen 4 provided above and below the screen 4 in a state where there is no vertical slack. A tensioning mechanism for making the screen 4 stretched in the screen frame 1 tightly finished after the operating bar 15 is fitted and locked in the recess 18 on the surface of the screen frame 1 will be described. .

  Details of the tension mechanism in the above-described embodiment of the screen device according to the present invention are shown in FIGS. 1, 2, 6 and 7. This tension mechanism basically has an adjustment member 20 that adjusts the degree of tension of the screen 4 by moving the inner rail 8 accommodated in the concave groove 6 of the frame member 3 in the concave and convex direction in the concave groove 6. And an operator 25 for operating them is provided so as to be easily operated from the outer surface of the frame member 3.

  The tension mechanism according to the embodiment will be described in more detail. The adjusting member 20 provided on the pair of frame members 3 and 3 includes an inner rail in the groove 6 of the frame member 3 as shown in FIGS. The operation screw 25 for operating the adjusting member 20 is screwed into the screw hole 22 of the female screw piece 21. The screw 26 is formed. The screw 26 can be rotated by a tool 29 such as a screwdriver with respect to the frame material 3 of the screen frame 1, but the movement is held impossible by the attachment of a cover 27 or the like that restricts movement in the axial direction. is there.

  Accordingly, when the screw 26 is rotated by the driver 29 in the direction indicated by the arrow A in FIG. 7A, the female screw piece 21 moves in the direction of the arrow a. As a result, the inner rail 8 moves in the direction of the arrow a. When the screw 26 is rotated by a screwdriver 29 in the direction indicated by the arrow B in FIG. 5B, the female screw piece 21 moves in the direction of the arrow b. As a result, the inner rail 8 moves in the direction of the arrow b and takes a position where the screen 4 is tensioned.

  According to the tension mechanism having such a configuration, when the screen 4 is detached from the screen frame 1 or attached to the screen frame 1, the screen 4 is adjusted to a position where the screen 4 is relaxed by the operation shown in FIG. Then, after attaching the screen 4 to the screen frame 1, while confirming the degree of tension of the screen 4, the operation shown in FIG. 7B may be adjusted to a position where the screen is moderately tensioned. Since the screw 26 as the operation element 25 is provided so as to be operable from the outer surface of the frame member 3, the operation is very easy and the safety of the operation can be easily secured.

  In the example shown in the figure, the female thread portion 21 is attached to the support member 10 that supports the inner rail 8 in the concave groove 6 of the frame member 3, but the inner rail 8 and the support member 10 are integrated. As long as the operation element 25 is not deformed such as being bent by the operation of the operation element 25, the female screw part 21 can be integrated with the integrated inner rail 8. In the illustrated embodiment, the tension mechanism is provided on the left and right frame members 3 of the screen frame 1. However, in order to increase the safety of the operation, it is provided on only one of the left and right frame members 3. it can.
