Description

  The present invention relates to an external roll screen. More specifically, the present invention relates to a structure of a roll screen device suitable for retrofitting (post-installation) to an existing building.

  As roll screens installed on window frames, etc., both ends of the slider are equipped with sliders (support bars for pulling out or rewinding all of the screen fabric drawer ends simultaneously and uniformly) at the drawer end of the screen fabric that can be wound. A device that guides the vehicle with a pair of guide rails is used as, for example, a curtain device in a restaurant.

  In addition, as a so-called roll screen door using an insect screen on the roll screen fabric, fasteners with protrusions are attached to both sides of the roll-up insect screen, so that these protrusions are inserted into the guide rail and An apparatus that prevents a gap from being formed between the guide rail and the guide rail is used (see Patent Document 1).

  Here, the roll screen device is generally attached to the indoor side. However, if the roll screen device can be attached to the outdoor side, there is a case where the effect of improving the indoor cooling ability can be obtained by blocking light and heat. .

Japanese Patent Publication No. 1-61158 (Japanese Patent Laid-Open No. 60-19892)

  However, any conventional roll screen device is a so-called internal device that can be attached to the indoor side, and is not a dedicated external structure. That is, when a roll screen originally designed for indoor use is used outdoors, there is a problem in terms of strength and durability because it is exposed to wind and rain. In addition, the roll screen door described above is also suitable for indoor use, and since the fasteners are used to enable the side portions of the insect screen to be separated, the fasteners may come off due to the influence of wind pressure or may be broken in some cases. There is a risk of doing.

  In addition, if a roll screen is to be retrofitted to a window frame of an existing building, a fastener such as a screw is required, but a screw hole must be provided for screwing, and further when screwing Some scratches are left on the window frame, such as being scratched. However, if an adhesive is used, the roll screen cannot be removed, or even if it is removed, adhesion marks remain, and further, there is a risk of causing some deformation in the window frame or the like. These problems can be particularly problematic in rental properties, and there is also a problem that even if it is desired to install a roll screen, it is practically difficult to retrofit and the application range is narrow.

  Then, an object of this invention is to provide the external roll screen of a structure suitable for retrofitting to the window frame of the existing building from the outdoor side.

  To achieve this object, an external roll screen according to the first aspect of the present invention comprises a roll screen fabric wound up by a roller, a slider attached to the leading edge of the roll screen fabric and pulling out the roll screen fabric evenly. The locked portion formed along both sides of the roll screen fabric, and the roll screen fabric and the slider in the drawing direction or the winding direction while restricting the locked portion from coming out of the roll screen fabric. A pair of parallel guide rails for guiding, and fasteners such as screws using the shape of the existing rails and other edges formed on the window rail to the outdoor window frame of the building. And a mounting stay that is detachably attached without being used.

  This roll screen realizes a structure suitable for external attachment by making it possible to attach using the existing edge formed on the outdoor window frame. In other words, the window frame is not marked because it has an external structure that can be mounted without using a fastener by a versatile mounting stay that can be mounted on the edge of an existing sash. Moreover, since it is a structure in which external attachment is taken into consideration from the beginning, it can be provided with the strength and durability necessary for exposure to wind and rain in advance, and can have a structure suitable for outdoor use. .

  Moreover, since the locked portions on both sides of the roll screen fabric are always locked so as not to come out of the guide rail, both ends of the roll screen fabric do not come out of the guide rail due to wind pressure. For this reason, when the wind is received, the roll screen fabric does not come off and turn over, and there is no damage caused by the strong wind and rain. Moreover, there is no possibility that both sides of the fabric may come off or break as in the case of a device having a fastener. In addition, when the roll screen fabric is pulled out, both sides of the roll screen fabric are locked in the guide rail, and are kept sealed without a gap.

  In addition, an incidental effect of enhancing the security (security) function of the residence can be obtained. That is, when fully closed by roll screen fabric, the glass window is completely covered and the impression that it is easy to break and break into the glass window will not be given. It can be an incentive to be jealous. In this case, since it has a double structure with a conventional window, it is difficult to complete the act of breaking the window and stealing the money, and it can be expected that the risk of actual damage will be reduced.

  The above external roll screen locks the slider by providing the slider and the guide rail with a lock member for preventing the roll screen material from unwinding and a stopper for locking the lock member, as in the second aspect of the invention. The lock release device that enables the lock member to be unlocked is provided on the indoor side of the slider or guide rail, and the roll screen fabric covers the window frame. It is preferable to prevent this.

  According to such an external roll screen, by locking the slider with the lock member and the stopper, it is possible to hold the roll screen fabric in a state where a desired amount is pulled out as in the conventional roll screen device. In addition, a lock release device for releasing the locked state is provided on the indoor side so that when the roll screen fabric is fully closed, the lock release device cannot be operated from the outdoor side. No gap is formed in any part between the window frame and the roll screen fabric, so that it is kept shielded so that fingers and hands cannot be inserted between the window frame and the roll screen. It becomes impossible to operate the unlocking device.

  Moreover, it is also preferable to make the roll screen fabric breathable as described in claim 3. In such a case, in the fully closed state, air can be secured while performing functions such as sunshade, light shielding, insect repellent and the like, so that it functions in the same way as a roll screen door that can be rolled in and accommodated when unnecessary.

  As is clear from the above description, according to the external roll screen according to claim 1, which is provided with a versatile mounting stay that can be mounted on an existing sash or the like, the window frame can be attached and detached without a mark. A structure suitable for external attachment is realized. Moreover, a roll screen having a structure suitable for outdoor use can be obtained by providing strength and durability necessary for wind and rain in advance.

  Further, since the locked portions on both sides of the roll screen fabric are always locked so as not to come out of the guide rail, both ends of the fabric do not come out of the guide rail due to wind pressure. For this reason, when the wind is received, the roll screen fabric does not come off and turn over, and there is no damage caused by the strong wind and rain. Moreover, there is no possibility that both sides of the fabric may come off or break as in the case of a device having a fastener.

  In addition, when the roll screen is attached to the outdoor side, not only the same effects as conventional products such as insect protection, sunshade, and light shielding, but also the effect of blocking light and heat is increased, and the room cooling capacity and efficiency are improved. The effect becomes.

  In addition, when the roll screen is fully closed, the glass window is completely obscured, so it does not give the impression that it is easy to break through the glass window and invade the act of entering the residence. It becomes. For this reason, the incidental effect of improving the security (crime prevention) function of a residence etc. is also acquired.

  According to the external roll screen according to claim 2, wherein the lock release device for releasing the lock state is provided on the indoor side, the lock release device cannot be operated from the outdoor side when the roll screen fabric is fully closed. For this reason, the window frame can be kept shielded when the roll screen is fully closed, and the security function can be further enhanced.

  According to the external roll screen according to claim 3, a roll that can be accommodated and capable of securing ventilation while performing functions such as sunshade, light shielding, insect repellent, etc. in a fully closed state by making the fabric breathable Can function as a screen door.

  Hereinafter, the configuration of the present invention will be described in detail based on embodiments shown in the drawings.

  1 to 16 show an embodiment of the present invention. The external roll screen 1 of the present invention includes a roller 2, a roll screen cloth 3, a slider 4, a locked portion 5 formed on the roll screen cloth 3, and the roll screen cloth 3 and the slider 4 in the pulling direction or A pair of parallel guide rails 6 for guiding in the winding direction and an attachment stay 8 for attaching the guide rails 6 to the outdoor window frame 7 of the building are provided. The “window frame” in this specification includes not only a window frame of a size that does not allow people to enter and exit, such as a so-called small window, but also a window frame such as a sliding door 12 provided so that people can enter and exit. Even the door frame is included.

  The size of the external roll screen 1 is not particularly limited, and various sizes can be applied depending on the size of the installed window or sliding door. For example, the external roll screen 1 can be applied to the sliding door 12 of a condominium balcony. It is also suitable for application (see FIG. 7). Hereinafter, the manual type external roll screen 1 provided for the sliding door 12 of the balcony as shown in FIG. 7, that is, the roll screen dough 3 is manually pulled down and the roll screen is utilized by utilizing the return force of the roller 2. The external roll screen 1 of the type that rewinds the dough 3 will be described.

  The roller 2 is a device that winds up the roll screen dough 3 and exerts a return force for rewinding the drawn roll screen dough 3 using an elastic member such as a torsion coil spring (see FIG. 1). The roller 2 has an axial length longer than the width of the roll screen fabric 3.

  The roll screen fabric 3 is a fabric that functions as a screen that covers the window, and is provided so as to be wound up by the roller 2. The roll screen fabric 3 is appropriately selected from a light-shielding fabric, a water-resistant fabric, a breathable fabric and the like according to the type and application of the window on which the roll screen 1 is installed. In any case, it is desirable that the fabric 3 is flame retardant. For example, in the present embodiment, conventional products such as a mesh light shielding fabric, a black curtain fabric, a sound insulation fabric, and an insect net are used as the roll screen fabric 3.

  Locked portions 5 are formed on both sides of the roll screen fabric 3 (see FIGS. 1 and 3). The locked portion 5 is provided to restrict both sides of the roll screen fabric 3 guided by the guide rail 6 from coming out of the guide rail 6. For example, as in the present embodiment, the channel shape The guide rail 6 has a bulging portion having a diameter larger than the opening width. However, this is only an example, and it is sufficient if the guide rail 6 is formed in accordance with the shape of the guide rail 6. It may be provided in a bowl shape so as to be caught on the opening edge of the inner rail or the inner rail 6b. In this embodiment, the guide rail 6 has a double structure composed of an outer rail 6a that forms an outer frame and a resin inner rail 6b that is incorporated in the guide rail 6. A plurality of metal balls that fit into the grooves of the rails 6b are provided to form a locked portion 5 (see FIGS. 3 and 4; hereinafter, referred to as “metal balls 5”). The metal balls 5 are steel members formed in a spherical shape or an elliptical shape (see FIG. 6), and a plurality of metal balls 5 are provided in a line at almost equal intervals. For example, in the present embodiment, the metal balls 5 are first welded to both sides of the roll screen fabric 3, and are further processed firmly and attached by sewing. In this case, in order for the roll screen fabric 3 to be smoothly drawn out or wound up without being caught, it is preferable that the installation interval of these metal balls 5 is narrow and the gap between them is as small as possible. As described above, in the case of the external roll screen 1 of the present embodiment in which the metal balls 5 are provided on both sides of the roll screen fabric 3, the roll screen is restricted so that the metal balls 5 do not come out of the guide rail 6. When 1 is in a fully closed state, no gap is formed in any part between the window frame 7 and the roll screen fabric 3, and a shielded state can be achieved so that fingers and hands cannot be inserted.

  The slider 4 is a rod-like member attached to the leading edge of the roll screen cloth 3, and the roll screen cloth 3 is evenly drawn from the roller 2 by moving in parallel while being guided by the guide rail 6 at both ends. Conversely, the roller 2 is evenly rewound. Lock members 9 for stopping the slider 4 at a predetermined position on the guide rail 6 are provided at both ends of the slider 4, and the lock member 9 is unlocked at the center of the slider 4. An unlocking device 11 is provided.

  A pair of guide rails 6 guides the roll screen fabric 3 and the slider 4 in the drawing direction or the winding direction while restricting the locked portions 5 on both sides of the roll screen fabric 3 from slipping out of the roll screen fabric 3. It is comprised by the rail. As described above, the guide rail 6 of the present embodiment has a double structure including the outer rail 6a and the inner rail 6b, and the resin-made inner rail 6b having a groove inside the outer rail 6a having a channel shape is accommodated. It has a structure. The groove of the resin inner rail 6b is formed in a channel shape that accommodates the metal ball 5 that is movable in the longitudinal direction (vertical direction in the case of the present embodiment) while restricting the metal ball 5 from slipping out inward. . However, the groove shape of the inner rail 6b is not limited to such a channel shape, and if the locked portion 5 is provided in a hook shape as described above, for example, the hook portion that hooks the hook portion. It may be a shape having The outer rail 6a is provided with a bracket 6c for connecting the guide rail 6 to the mounting stay 8 directly or via the connector 22 (see FIG. 1 and the like).

  A stopper 10 for locking the lock member 9 of the slider 4 is provided on the side facing the inner side of the guide rail 6 (see FIG. 1 and the like). In this embodiment, the stopper 10 has a wedge shape as shown in FIG. 1, and the lock member 9 rides along the inclined surface of the stopper 10 when the roll screen fabric 3 and the slider 4 are pulled out (pulled down). When the roll screen dough 3 is wound up, the lock member 9 is stopped by the end face of the stopper 10 so that the roll screen dough 3 is not rewound further.

  The lock member 9 provided on the slider 4 is urged so as to protrude outward by an urging means (not shown) (see FIG. 3), and when it gets over the stopper 10, it is temporarily pushed inward and gets over. After that, it protrudes again, for example, has a rounded prismatic shape, and always protrudes toward both sides by a predetermined amount (see FIG. 3). In this embodiment, lock pieces 9 a and 9 b are provided at both ends of the slider 4, and the pair of lock pieces 9 a and 9 b are engaged with a stopper 10 provided on the guide rail 6.

  The lock release device 11 is a device for releasing the lock state of the lock member 9. For example, in the case of the present embodiment, the pair of slide pieces 11 a and 11 b for pulling the lock pieces 9 a and 9 b on both sides is provided at the center of the slider 4. This allows the lock state to be released (see FIG. 1 and the like). Although not shown in particular, the pair of slide pieces 11a and 11b are connected to each other so as to interlock with the lock pieces 9a and 9b, and the slide pieces 11a and 11b are slid by a predetermined amount to lock pieces 9a and 11b. 9b is pulled in by an amount capable of releasing the locked state. In this embodiment, the lock pieces 9a and 9b and the slide pieces 11a and 11b can be operated independently from each other on the left and right sides. However, for example, both mechanisms may be linked so as to slide by the same amount by connecting them with a rack and gears. Absent. In any case, the lock is released only when the left and right lock pieces 9a and 9b are pulled in, and the slider 4 can be moved.

  In this embodiment, the lock release device 11 is provided on the slider 4 and on the indoor side of the external roll screen 1 (see FIG. 9 and the like). For this reason, according to this external roll screen 1, it is impossible to perform the unlocking operation from the outdoor side by setting the roll screen fabric 3 to the fully closed state and locking the lock member 9 with the stopper 10. Become. Therefore, the external roll screen 1 of this embodiment can form a double structure with an existing glass window or the like by being externally attached to the window frame 7, and is more secure than a single structure having only a glass window or the like. Function can be enhanced. Moreover, since the device for unlocking the inside of the window frame 7 and the unlocking is not visible from the outdoor side by setting the fully closed state, there is also an effect of suppressing criminal psychology such as entering the house.

  The mounting stay 8 is a member for attaching the above-described guide rail 6 to the outdoor window frame 7 of the building in an attachable / detachable state, and the existing rail and other edges formed on the window frame 7 This embodiment is configured as follows so that it can be externally attached without using a fastener such as a screw. That is, an edge portion 14a which is bent outwardly from the sash 14 of the sliding door 12 and the screen door 13 so as to face the inside of the window frame is used (see FIG. 14 and the like), and this edge is formed by the grip portion 8a. It is configured to be attached to the sash 14 with the portion 14a sandwiched therebetween. The grip portion 8a has a clip shape that can sandwich the edge portion 14a by using the elasticity of the folded portion. When the grip portion 8a is attached to the edge portion 14a, the position and orientation of the guide rail 6 are maintained almost uniquely. It is formed to have a degree of elasticity and strength. In this case, as shown in FIG. 14, if, for example, two claws are provided on the inner surface of the gripping portion 8a, the gripping portion 8a is difficult to be displaced and can be prevented from falling off the edge portion 14a. Thus, according to the mounting stay 8 attached to the sash 14 so that the edge portion 14a is sandwiched between the clip-shaped gripping portions 8a, the roll screen can be removed without any damage to the sash 14 or the window frame 7. It becomes possible to attach. Moreover, according to the mounting stay 8 having such a structure, it is possible to remove the roll screen 1 from the sash 14 without using a special tool, for example, when changing the external roll screen 1 itself. There is still no scratches. For this reason, the external roll screen 1 of this embodiment is particularly suitable when retrofitting (post-installation) to an existing building. Further, when a so-called standard product having a general shape is used as the sash 14, it can be used widely without having to prepare various types of mounting stays 8.

  Further, a housing 16 for accommodating the roller 2 and the roll screen fabric 3 is provided on the upper part of the external roll screen 1 (see FIG. 1 and the like). The housing 16 functions as a cover that covers the roller 2 and the roll screen fabric 3 wound by the roller 2 and also functions as a bearing for the roller 2. For example, the housing 16 of this embodiment includes a bracket 16a having an L-shaped cross section, a cover 16b that can be attached to and detached from the bracket 16a, and a side cover 16c that closes both sides. The side cover 16c functions as a bearing that holds the shaft end of the roller 2 by a through hole (or recess) 16d provided in the center thereof (see FIG. 1 and the like). In FIG. 1 and the like, only a simple box-shaped housing 16 is illustrated, but in reality, a shape in which a part of the roller 2 and the roll screen fabric 3 is convex is formed in accordance with the shape when the roller 2 and the roll screen cloth 3 are wound. It is preferable to reduce the capacity of the housing 16 and improve the design (see FIG. 11 and the like).

  Next, the structure of the external roll screen 1 provided on the left and right sliding doors 12 will be described below with reference to FIGS.

  In the external roll screen 1, a guide rail base material 15 made of a square pipe and functioning as a frame for reinforcing the entire external roll screen 1 is interposed between the guide rail 6 and the mounting stay 8. (See FIG. 13 etc.). In this case, it is also preferable to make a design shape such as a bulging shape formed by a curve whose curvature changes in the portion of the guide rail base material 15 exposed to the outdoor side (see FIG. 13 and the like).

  A connector 22 is provided between the guide rail base 15 and the mounting stay 8 so that both members can be attached and detached (see FIGS. 11 and 14). For example, in the present embodiment, the connector 22 is constituted by two pairs of elastic claws, and both the members can be integrated by engaging the claws on one side so as to be pushed into the claws on the other side. The claws are removed by twisting so that both members can be removed.

  The external roll screen 1 provided in the sliding door 12 is installed on the left and right sides of the window frame 7 with the guide rails 6 (or guide rail base materials 15) located near the center of the window frame 7 being adjacent to each other. (See FIG. 8 and the like). In this case, in this embodiment, the four guide rails 6 and the four guide rail base materials 15 all have the same structure (see FIG. 8, FIG. 16, etc.), but the adjacent guide rails 6 and guide rail bases are previously provided. A structure in which the materials 15 are integrated may be used. The two roll screen fabrics 3 arranged side by side can be opened and closed independently (see FIGS. 7 and 8).

  The housing 16 is attached to the upper edge portion 14b of the sash 14 (see FIG. 11). Specifically, a mounting stay 8 having a clip-shaped gripping portion 8a is provided on the indoor side of the housing 16 (see FIG. 11), and the edge portion 14b is sandwiched between the gripping portion 8a and the sash 14 is inserted. It is designed to be detachable.

  Further, a cleaning member 17 is provided on the inner side of the winding groove 16e of the roll screen dough 3 in the housing 16 so as to come into contact with the front and back surfaces of the roll screen dough 3 drawn out from the roller 2 or taken up by the roller 2. (See FIG. 11). As the cleaning member 17, it is preferable to apply a material that has moderate softness such as mohair and can be cleaned without damaging the fabric.

  Further, the frame of the external roll screen 1 can be formed in a gate shape with the frame member on the three sides of the upper housing 16 and the left and right guide rails 6 to which the upper ends thereof are connected. Further, a frame member is provided in the lower part to form a rectangular frame. The lower frame member is composed of a cushion material 18 provided at the step portion of the lower window frame 7 and a channel-like plate frame 19 covered on the portion to become the cushion material 18 (see FIG. 12). ). Although not particularly illustrated, adjacent frames (that is, the upper housing 16, the left and right guide rails 6, and the lower frame members 18 and 19) are connected by a fastener such as a screw.

  The bottom surface of the slider 4 is provided with an absorbent material 20 for reducing an impact when the slider 4 pulled down to the lower end contacts or collides with the plate frame 19 (see FIG. 12). As the absorbent 20, a material that is easy to absorb and relieve shock and impact noise and that is easily elastically deformed so as to easily fill the gap between the slider 4 and the plate frame 19 is preferable. In the present embodiment, as shown in the drawing, a hollow rubber material having a circular arc on the lower side is used as the absorbent material 20.

  Furthermore, a stopper 21 is provided on the indoor side of the slider 4 so as to abut against the bottom of the housing 16 and restrict the winding of the roll screen fabric 3 (see FIGS. 10 and 12). Similar to the absorbent material 20 described above, the stopper 21 is also preferably made of an elastic member such as a rubber material that can be easily deformed, and can sufficiently reduce the collision noise at the time of collision with the housing 16.

  The external roll screen 1 of the present embodiment described above functions not only as a light shielding screen that can appropriately block outdoor light depending on the amount of opening and closing, but also as a shield instead of a shutter. It can be. That is, for example, in a room without a shutter, which is often found in an apartment, the external roll screen 1 serves as a blind curtain, and thus functions as a blindfold for such a room, and the inside of the room is visible from the outside through a glass window. It is possible to avoid such a situation.

  Further, when the roll screen fabric 3 is made of a non-breathable material, if the roll screen fabric 3 is pulled down to a fully closed state, it becomes a double structure with a glass window and can be used as a heat insulating material that enhances heat insulation in the room. Will work. In addition, since both sides of the roll screen fabric 3 have a sealed structure with no gap between the guide rail 6, the roll screen fabric 3 can function as a protective screen that prevents pollen from entering the room, for example.

  On the other hand, when the roll screen fabric 3 is made of a mesh material and has air permeability (air permeability), on the other hand, a gap through which insects can enter the existing window frame 7 It is possible to function as a roll screen door that allows only ventilation without forming. For this reason, for example, even in a room where a screen door such as an existing one-room apartment is not installed, it is possible to provide an environment in which ventilation is possible while preventing invading insects and the like to residents.

  In addition, the external roll screen 1 as described above has an effect of deterring criminal psychology for existing buildings. That is, for example, for the theft act of breaking a part of a glass window and removing the key to enter, if the glass window is covered with the roll screen fabric 3, the position of the window key cannot be confirmed at a glance. Even if an attempt is made to break the roll screen fabric 3 to release the key of the roll screen 1, it takes a lot of time to confirm the key position.

  The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the scope of the present invention. For example, in the present embodiment, the case where the present invention is applied to the window frame 7 of a house such as a condominium has been described. However, the present invention is not limited to this, and other than a single-family house, a hotel or resort-related accommodation facility or this The present invention can also be applied to a staying facility or the like that is attached, and is also suitable when applied to a restaurant such as a suburban restaurant. That is, in general, roll screens and scooping curtains (something called roman shades) in restaurants are installed inside the window, that is, in the store, and the fabric can be raised and lowered indoors However, according to the external roll screen 1 according to the present invention, the screen is installed outside the window, that is, outside the store. It is possible to make the light shielding device completely different from the conventional one. The roll screen 1 installed outside the window does not give any uncomfortable feeling to the customer because it is outside the window 3 even if the fabric 3 is dirty.

  Furthermore, such an outside roll type external roll screen 1 can be provided with an advertising function. That is, by describing, for example, a store menu or advertisement on the roll screen fabric 3, the advertisement function can be exhibited with the roll screen fabric 3 pulled out. Moreover, by describing advertisements on both sides of the roll screen fabric 3, not only customers who eat and drink in the store but also passers who pass outside the store can be added to the advertisement.

  Further, such an external roll screen 1 installed outside the store may be a manual type in which the store clerk raises and lowers one by one, but an automatic type is preferable from the viewpoint of work efficiency. The electric external roll screen 1 that automatically pulls out and winds up the roll screen fabric 3 will be described below (see FIGS. 17 and 18). As shown in FIG. 17, the roller 2 is a hollow roller having a larger diameter (for example, about 130 mm in outer diameter) than that of the above-described embodiment. The roller 2 is supported by brackets 23 at both ends of the rotating shaft. Although not shown, the rotation of the motor is transmitted to the roller 2 by a transmission mechanism including a pulley, a belt, a gear train, or the like. In addition, the guide rail 6 absorbs the dimension error of the joinery or secures a margin for movement when the roll screen fabric 3 is attached / detached, so that the inner rail 6b is positioned in the width direction of the roll screen fabric 3 within the outer rail 6a. Are formed so as to have a gap that can move slightly (see FIG. 18). When the external roll screen 1 is installed outside the store, the roll screen fabric 3 may be momentarily turned due to the influence of the wind, but the inner rail 6b strokes in the width direction so that the roll screen fabric 3 The pulling force acting instantaneously can be relaxed.

  The external roll screen 1 installed outside the store does not necessarily have to include the lock member 9, the stopper 10, and the lock release device 11. That is, in this case, a roll screen dough 3 drawn out from the roller 2 and the slider 4 can be held at a certain position by a known device, for example, the roller 2 and the roll screen dough 3 is slightly If it has an automatic locking device device provided with a ratchet mechanism that is disengaged when pulled out, the roll screen fabric 3 can be held in a state of being pulled out by a desired length, and can function as a screen. .

  All of the external roll screens 1 described so far have been used to draw out and wind up the roll screen fabric 3 in the vertical direction. A sliding structure is also possible.

  In the above description, the case where both the guide rails 6 are straight (vertical) or parallel to the side has been described. However, in this specification, the parallelism in the case of “a pair of parallel guide rails 6” is as described above. As long as the distance between the two guide rails 6 is constant, for example, the guide rail 6 may be curved in the middle. For example, although not specifically illustrated, The case where the side half is straight but the upper half is curved so as to warp outward is also included.
