  1 to 7 show a first embodiment of a horizontal screen device according to the present invention. The screen frame 1 in the horizontal drawing screen device includes a pair of vertical frames 2 and 3 and upper and lower horizontal frames 4 and 5 as clearly shown in FIGS. The vertical frames 2 and 3 are configured as a winding box of a winding type screen device having one winding frame 12 inside which one of the vertical frames 2 winds the screen 10, and the other vertical frame 3. However, when the screen 10 is in the extended state, the operation frame 14 attached to one end of the screen 10 is configured as a receiving frame that abuts.

  One end of each of the horizontal frames 4 and 5 is connected to upper and lower ends of a vertical frame 2 forming a winding box, and the other end is connected to upper and lower ends of a vertical frame 3 forming a receiving frame. The screen winding mechanism provided in the winding box is such that the screen 10 is wound and stored on the winding shaft 12 by the urging force of a spring (not shown) provided in the winding shaft 12. . The screen 10 can be configured as a net for an insect screen, but is not limited thereto.

  The upper and lower horizontal frames 4 and 5 move the upper and lower ends of the screen 10 and the operation frame 14 attached to one end of the screen and operated to open and close the screen between the extended position and the storage position of the screen. And a pair of guide edges 6 and 5 each of which is formed of a shape having grooves 4a and 5a opened on the sides facing each other, and inwardly facing the edges of the openings. 7 are protruded. On the other hand, as shown in FIG. 2, a pair of upright walls 16 guided by inner surfaces of a pair of guide edges 6 and 7 of the horizontal frames 4 and 5 are provided on both upper and lower ends of the operation frame 14, as shown in FIG. The upper and lower ends of the operation frame 14 are guided along the opening and closing directions of the screen 10 by the guide edges 6 and 7.

  Further, a guide rail 20 is accommodated in the groove portion 5a of the lower horizontal frame 5 as a guide portion that supports the lower end of the operation frame 14 and guides the lateral movement thereof. The guide rail 20 has a flat surface 20b formed above a support substrate 20a to be held on the inner bottom of the groove portion 5a of the lower horizontal frame 5 and is provided between a pair of upright walls 16 at the lower end of the operation frame 14. It is a rolling surface for rolling a pair of rolling wheels 17.

  In the illustrated first embodiment, a similar guide rail 20 is also accommodated in the upper horizontal frame 4, but as will be described later, this horizontal drawing screen device moves the screen frame 1 within the frame plane. Since the hanging base can be changed left and right by rotating by 180 °, the guide rails 20 in the horizontal frames 4 and 5 have the same shape so as to function as a lower horizontal frame when the screen frame 1 is inverted. This is because they are used. Therefore, in the upper horizontal frame 4, the guide rail 20 does not directly guide the operation frame 14, but the movement of the operation frame 14 together with the pair of guide edges 6 provided on the rim of the groove portion 4 a. It can be said that it is a guide part in that the road is set.

  Although not shown, a large number of engaging pieces are attached to the upper and lower edges of the screen 10 in a row so as to hold and move the upper and lower ends of the screen 10 laterally. As the engagement pieces attached to the upper and lower ends of the screen 10, a half of a general-purpose fastener or a material having a similar structure can be used. On the other hand, on the back of the flat surface 20b of the guide rail 20 in the upper and lower horizontal frames 4 and 5, an engaging groove 20c is provided in the center of the flat surface to open a slit 20d. By engaging the mating pieces, the upper and lower ends of the screen 10 are held by the slits 20d, so that the screen 10 can be moved laterally.

  In order that the operation frame 14 can be locked at that position in a state where the screen 10 is spread over the entire surface of the screen frame 1, the upper and lower horizontal frames 4 and 5 are provided with the operation frame when the screen 10 is in the expanded state. Without providing the guide rail 20 to the screen extending portion where the 14 is located, the lower locking member 23 is replaced with the lower rail 5 instead of the guide rail at that portion in the lower horizontal frame 5, and the upper locking is performed on the same portion in the upper horizontal frame 4. A member 24 is provided. The lower lock member 23 guides the lateral movement of the operation frame 14 to the extended portion side thereon. When the operation frame reaches the screen extended portion, the lower hook 23a provided therein operates. It locks to the lower end of the frame 14 to prevent the operation frame from moving in the storage direction.

  The configuration of the lower lock member 23 will be described with reference to FIGS. 1 to 6. The lower lock member 23 is assumed to constitute an extension of the guide rail 20 at the end of the guide rail 20 on the vertical frame 3 side. It is arranged on a base 25 provided on the inner bottom of the groove portion 5a of the lower horizontal frame 5 so as to be tiltable as described later. The lower lock member 23 does not have a rolling surface that constantly rolls the wheel 17 of the operation frame 14. When the screen 10 is extended by the operation frame 14, the lower lock member 23 sequentially guides the screen 10 as described below. Finally, as shown in FIG. 1, the lower ends of the pair of upright walls 16 provided at the lower end of the operation frame 14 are provided on the lower lock member 23 at the winding box side end. The operation hook 14 is locked to the lower hook 23a to prevent lateral movement of the operation frame 14 in the storage direction.

  More specifically, the lower lock member 23 is attached to the base 25 extending from the end of the lower horizontal frame 5 on the vertical frame 3 side to a substantially central portion of the lower lock member 23, as shown in FIG. The fulcrum of the tilt is located near the end of the base 25 in the middle part of the lower surface of the lower lock member 23, and the guide projection 25a is erected upward from the base 25. Is inserted into a vertical groove 23b in the lower lock member 23 to guide the vertical movement, and can be tilted between the postures shown in FIG. 1 and FIG. A pair of lower hooks 23a on both sides of the lower lock member 23 has a slope 23c whose side facing the guide rail 20 is pressed down by pressing by the lower end of the operation frame 14, and is further vertically than the lower hooks 23a. On both sides of the lower lock member 23 on the side of the frame 3, there is formed a mounting portion 23d on which the lower end of the upright wall 16 of the operation frame 14 moved to the screen extension portion is mounted.

  The state of the guide of the operation frame 14 in the lower lock member 23 will be sequentially described. When the operation frame 14 at the position shown by the dashed line in FIG. 1 is moved in the direction in which the screen 10 is extended along the guide rail 20, first, The lower end of the operation frame 14 comes into contact with the slope 23c of the lower hook 23a, and the operation frame 14 rides on the lower lock member 23 after pushing down the slope 23c. Thereafter, when the operation frame 14 further moves, as shown in FIG. 3, the tip of the lower end of the operation frame 14 reaches the mounting portion 23d, which is inclined, and then moves while pressing the mounting portion 23d. Is what you do.

  When the tip of the operation frame 14 gets over the fulcrum of the lower lock member 23, the operation frame 14 exerts a force on the lower lock member 23 to return the mounting portion 23d to a horizontal position. The rolling wheel 17 also reaches the lower lock member 23 immediately before or after that, but in any case, if the standing wall 16 at the lower end of the operation frame 14 reaches a position beyond the lower hook 23a of the lower lock member 23, Due to the gravity of the operation frame 14, the mounting portion 23d of the lower lock member 23 takes a horizontal posture, and the standing wall 16 of the operation frame 14 is mounted thereon as shown in FIG. This position is a position where the operation frame 14 is located at the screen extending portion and the operation frame 14 is locked to the lower hook 23 a of the lower lock member 23.

  After the operation frame 14 reaches the lower lock member 23, when the standing wall 16 of the operation frame 14 passes over the lower hook 23a, the operation frame 14 is slightly moved by the operator's hand through the operation frame 14. May be felt, but the response is acceptable as a signal to notify the operator that the operation frame 14 has reached the lower lock member 23. However, if it is desired to make it smaller, all or part of the lower lock member 23 itself or a mechanism for holding it on the base 25 with the stator 27 is formed of an elastically deformable material, and 14 may be reduced. Even if the operation frame 14 moves up and down as described above, it does not deform or wrinkle when the screen is extended.

  As a mounting structure of the lower lock member 23 to the base 25 by the stator 27, a pair of spiral grooves is provided in a fixing hole provided in the base 25 fixed to the mounting position of the lower lock member 23 in the horizontal frame 5. The lower lock member 23 is fixed to the mounting hole 23e provided at a position corresponding to the fixing hole of the base 25 in the lower lock member 23 by the stator 27 rotatably snap-fixed with an elastic ring or the like. The stator 27 has a pair of pins that are engaged with a spiral groove provided in a fixing hole of the base 25 and protruded from a peripheral surface thereof. Through the helical groove, and is held in the fixing hole in a direction orthogonal to the moving direction of the operation frame 14, thereby enabling the above-described tilting of the lower lock member 23.

  As described above, in this horizontal drawing screen device, the screen frame 1 is turned upside down so that the hanging base can be changed left and right. In this case, the upper and lower locking members 24 and 23 in the upper and lower horizontal frames 4 and 5 are used. Therefore, the lower lock member 23 and the upper lock member 24 share the base 25 for fixing them to the horizontal frames 4 and 5, and the lower lock member 23 and the upper lock member 24 The stator 27 of the upper lock member 24 is also shared, and is configured to be easily replaceable. When the lower lock member 23 is removed, the pin of the stator 27 moves in the spiral groove by rotating the stator 27 in the reverse direction, so that the lower lock member 23 rises from the base 25. , Can be easily removed.

  According to the horizontal screen device provided with the lower lock member 23 having the above-described configuration, the operation frame 14 is located at the extended position of the screen 10 as in a dropping method known as a lock mechanism for the operation frame (see Patent Document 1). When the operation frame is reached, the operation frame itself is not dropped into the recess of the guide rail, and only the lock member is shifted to the lock state, so that the screen in the extended state is wrinkled under the influence of the lock mechanism. Never be.

  In order to unlock the lower end of the operation frame 14 by the lower lock member 23, the operation frame 14 of the screen 10 in the expanded state is lifted as shown in FIG. The operation hook 14a may be straddled by raising the operation hook 14a, and the operation hook 14a is moved in the storage direction by the guide of the lower horizontal frame 5 by straddling the lower hook 23a. It becomes possible. The operation frame 14 is lifted at a position where the lower end of the operation frame 14 is locked by the lower lock member 23, as described later with reference to FIGS. 1 and 5. Since the upwardly movable space 8 is formed in the inside, no trouble is caused.

  Since the urging force of the take-up spring in the take-up shaft 12 acts on the operation frame 14 via the screen 10, the screen 10 can be stably formed only by locking the lower end of the operation frame 14 by the lower lock member 23. When it is not possible to hold the operation frame 14 in the screen extended portion, or when it is desired to stably hold the operation frame 14 at the screen extended portion, the upper lock member 24 described below is moved upward above the position provided with the lower lock member 23. What is necessary is just to provide in the horizontal frame 4. As described above, the screen frame 1 is turned upside down so that the hanging base can be changed left and right. In this case, in order to easily replace the mounting positions of the upper and lower lock members 24 and 23, both lock members are connected. Since the base 25 and the stator 27 to be fixed are shared, description thereof will be omitted.

  The configuration of the upper lock member 24 will be described with reference to FIGS. 1 to 5 and FIG. 7. The upper lock member 24 is vertically positioned at the inner bottom of the groove portion 4 a that opens downward on the upper horizontal frame 4. A base 25 extending from the side end of the frame 3 to a substantially central portion of the upper lock member 24 is held by a stator 27 so as to be tiltable. The fulcrum of the tilt is at a substantially central portion of the lower surface of the upper lock member 24. In the vicinity of the end of the base 25. The upper lock member 24 is tiltable between the postures shown in FIGS. 1 and 4, but is always kept in the state shown in FIG. 1 by a spring housed therein.

As shown in FIG. 7, the upper lock member 24 includes a pair of upper hooks 24a protruding upward at portions protruding from the fulcrum toward the winding shaft 12 on both sides. The side of the hook 24a facing the guide rail 20 is part of the operation frame 14 approaching from the winding shaft 12 side for extending the screen 10, ie, a pair of the standing walls protruding upward from the upper end of the operation frame 14. It is formed on a slope 24b, which is pushed down by an engagement projection 16a protruding from the opposite surface side of the projection 16.
Note that the upper lock member 24 does not support the operation frame 14 itself, and thus does not include a portion that supports the operation frame 14 moved to the screen extending portion, such as the mounting portion 23d of the lower lock member 23.

  The state of the guide of the operation frame 14 in the upper lock member 24 will be described. The operation frame 14 at the position shown by the chain line in FIG. 1 is moved in the direction in which the screen 10 is extended along the guide rail 20, and the state of FIG. As shown in FIG. 4, the pair of engaging projections 16 a on the opposing surfaces of the pair of upright walls 16 protruding from the upper end of the operation frame 14 form a pair of engaging projections 16 a on the upper lock member 24, respectively. It comes into contact with the slope 24b on the back of the hook 24a.

  However, since the upper hook 24a is held by the spring (not shown) provided between the upper lock member 24 and the base 25 so as to be able to tilt downward, the engagement protrusion 16a pressing the inclined surface 24b is provided. When the operation frame 14 moves to the position shown in FIG. 1 when the operation stile 14 moves to the position shown in FIG. The upper hook 24a moves up to the position shown in FIG. Instead of the spring, the hook 24a itself may be elastically moved upward.

  In order to release the lock of the operation frame 14 whose upper and lower ends are locked as described above, the screen in the extended state is described in the same manner as described in the unlocking of the lower end of the operation frame 14 by the lower lock member 23. As shown in FIG. 5, the operation frame 14 may be lifted into the upper movable space 8 provided in the upper horizontal frame 4 on the operation frame 14. If the engaging projections 16a of the pair of projecting standing walls 16 are lifted to a height straddling the hook 24a, the operation frame 14 can be moved in the storage direction by the guide of the upper horizontal frame 4. . In lifting the operation frame 14, it is necessary that the height of the operation frame 14 is a height across the lower hook 23a that is moving up to the height at which the operation frame 14 is locked. The lock of the operation frame 14 whose end is locked can be simultaneously released.

  The above-described horizontal drawing screen device forms the outer shape of the screen frame 1 in a substantially vertically symmetrical shape, and allows the hanging source of the screen 10 to be changed left and right by rotating the screen frame 1 by 180 ° within the frame surface. However, at the time of the change, it is necessary to change the mounting position of the upper lock member 24 and the lower lock member 23 as described above. By changing the positions of the two lock members, the upper movable space 8 is inevitably formed in the screen extending portion of the new upper horizontal frame by attaching the upper lock member 24 thereto. .

  Next, a second embodiment of the horizontal screen device according to the present invention will be described with reference to FIGS. As clearly shown in FIGS. 8 and 9 and the like, the screen frame 31 in this horizontal drawing screen device includes a pair of vertical frames 32 and 33 and upper and lower horizontal frames 34 and 35 similar to the first embodiment. One vertical frame 32 is configured as a winding box provided with a winding shaft 42 of the screen 10, and the other vertical frame 33 is configured as a receiving frame with which an operation frame 44 of the screen 10 abuts. One end of each of the horizontal frames 34 and 35 is connected to the upper and lower ends of the vertical frame 32, and the other end is connected to the upper and lower ends of the vertical frame 33. The screen 10 is biased by a spring provided in the winding shaft 42. There is no difference between the first embodiment and the configuration such as winding and storing on the winding shaft 42.

  The upper and lower horizontal frames 34 and 35 guide the lateral movement of the upper and lower ends of the screen 10 and the operation frame 44 attached to one end of the screen and operated to open and close the screen 10 between the extended position and the stored position of the screen 10. In the same manner as in the first embodiment, grooves 34a and 35a are opened on their opposing surfaces, and a pair of guide edges 36 and 37 are protrudingly provided at the edges of the openings. Thereby, the outer surfaces of the pair of upright walls 46 provided at the upper and lower ends of the operation frame 44 are guided.

  Further, guide rails 50, 51 for guiding the lateral movement of the operation frame 44 are accommodated in the groove portions 34a, 35a of the upper and lower horizontal frames 34, 35. Among them, in particular, the guide rail 51 of the lower horizontal frame 35 has a flat surface above the support substrate 51a held on the inner bottom of the groove 35a of the lower horizontal frame 35, as in the first embodiment. 51b is formed as a rolling surface for rolling a pair of rolling wheels 47 at the lower end of the operation frame 44.

On the other hand, the guide rails 50 in the groove portions 34a of the upper horizontal frame 34, together with the guide rails 51 of the lower horizontal frame 35, form a large number of engaging pieces at the upper and lower edges of the screen 10 similar to the first embodiment. The slits 50d, 51d to be engaged are opened at the center of the flat surfaces 50b, 51b at the corresponding positions on the respective guide rails, and the upper and lower ends of the screen 10 are held by engaging the engaging pieces with the slits. , So that it can be moved laterally.
Note that the horizontal drawing screen device of the second embodiment does not include a configuration in which the hanging base is changed left and right by reversing the screen frame as in the first embodiment. Not only does the guide rail of the first embodiment partially differ, for example, there is no need to provide a rolling surface for the rolling wheel 47, but also the upper and lower guide rails 50, 51 have a difference in the configuration described below. .

  The structure of the lower lock member 53 of the second embodiment will be described. The lower lock member 53 provided on the lower horizontal frame 35 is arranged on the vertical frame 33 side of the guide rail 51 as an extension of the guide rail. A fulcrum 53e is disposed on the screen extending end side of the inner bottom of the groove 35a of the lower horizontal frame 35, and both sides of the lower lock member 53 are placed on the guide rail 51 side from above the fulcrum 53e. The mounting portion 53d of the operation frame 44 which extends and has a pair of hanging hooks 53a at the ends is supported by a spring member 53b so as to be tiltable. The pair of lower hooks 53a is such that the side facing the guide rail 20 is a slope 23c that can be pushed down by pressing by the lower end of the operation frame 44, and the mounting portions 53d on both sides of the lower lock member 53. Is formed so that the lower end of the standing wall 46 of the operation frame 44 moved to the screen extension portion can be placed.

  Therefore, when the lower end of the operation frame 44, which has moved the screen 10 to the extended portion side along the guide portion of the lower horizontal frame 35, hits the slope 53e of the lower hook 53a, the operation frame 44 rides on it. Due to its weight, the lower hook 53a is pushed down, and the operation frame 44 moves to the screen extending end side at the same height as the guide portion, and further, the operation frame 44 becomes lower than the lower hook of the mounting portion 53d. When it exceeds 53a, the hooks 53a are locked by the urging force of the spring members 53b at the lower ends of the pair of upright walls 46 provided on the operation frame 44, so that the lateral movement in the storage direction is prevented and the screen is held at the screen extended portion. Is done.

  When the lower ends of the pair of upright walls 46 provided at the lower end of the operation frame 44 are on the horizontal placing portion 53d of the lower lock member 53, the lower lock member 53 has a height of the operation frame 44. The height is set so that the rolling wheel 47 of the operation frame rolls on the flat surface 51b of the guide rail 51. Therefore, unlike the drop-in method of Patent Document 1, the screen attached to the operation frame is not deformed or wrinkled under the influence of the lock mechanism.

  On the other hand, the horizontal screen device according to the second embodiment includes an upper lock component 54 corresponding to the upper lock member 24 in the first embodiment. The configuration of the upper lock component 54 will be described. The upper lock component 54 is generally opened and closed by the operation frame 44 while being held up and down along a lifting guide 46 a provided on the operation frame 44. Slides along the slide rail 50e provided in the upper horizontal frame 34 in accordance with the above, when the operation frame 44 reaches the screen extending portion, it is dropped into the cut-out portion 50f of the slide rail 50e and engaged. It has a configuration to stop.

  More specifically, as clearly shown in FIGS. 15 and 16, the upper lock component 54 is slidable up and down on the upper outer surface of the upright wall 46 at the upper end of the operation frame 44 as an elevating guide 46 a. In the opening / closing operation stage of the screen 10 until the operation frame 44 reaches the screen extending portion, the sliding portion 54a, which is a part of the upper lock component 54, is attached to the upper horizontal frame. The slide rail 50e is slidably mounted on a slide rail 50e formed on the outer surface of the guide rail 50 in the inside 34, and the slide rail 50e is, as clearly shown in FIGS. The cutout 50f is formed, and the upper lock component 54 is dropped into the cutout 50f by a predetermined amount. Engaged thereby locked to the stopper portion 50g provided in the rail 50 or the like, the movement of the housing direction of the operating stile 44 is configured to be prevented.

In the second embodiment, the slide rail 50e is formed on the outer surface of the guide rail 50 (on the back side of the flat surface 50b). However, the present invention is not limited thereto. The protrusion 54b that comes into contact with the stopper 50g at the screen extending portion can be formed at an arbitrary portion of the upper lock component 54.
Further, in the illustrated embodiment, the upper lock component 54 is fitted on only one of the pair of upright walls 46, but both may be used, and an elevating guide 46a provided at a portion different from the upright wall 46 is used. You can also.

  As described above, in order to release the lock of the operation frame 44 in which the upper lock component 54 is locked together with the lower lock member 53, similarly to the unlocking of the lower end of the operation frame 44 by the above-described lower lock member 53, it is necessary to set As shown in FIG. 12, the operation frame 44 of a certain screen 10 may be lifted to the upper movable space 38 provided in the upper horizontal frame 4 on the operation frame 44, and thereby, By lifting and returning the upper lock component 54 fitted on the elevating guide 46a at the upper end onto the sliding rail 50e, the operation frame can be slidably moved in the storage direction by the guides of the upper and lower horizontal frames. , The operation frame 44 can be moved in the storage direction by the guide of the upper horizontal frame 4. In lifting the operation frame 44, it is necessary that the height of the operation frame 44 should be the height that straddles the lower hook 23a that is moving up to the height at which the operation frame 44 is locked at the lower end. The lock of the operation frame 44 whose end is locked can be simultaneously released.

  After the operation frame 44 is lifted to the upper movable space 38 at the screen extending portion, it is necessary to move the upper lock component 54 to the guide portion side and place it on the slide rail 50e. If the end of the screen extending portion 50a at the side of the screen extending portion 50a obstructs the movement of the operation frame 44, as shown in FIG. The movable space 38 may be enlarged.
