Description

  The present invention relates to a barrier-free horizontal pulling roll screen device to be attached to a building opening frame for the purpose of insect proofing, dustproofing, light shielding, blindfolding, decoration, etc., and in particular, the lower end of a horizontal pulling-up type screen. The present invention relates to a barrier-free horizontal pulling roll screen device that stabilizes the movement of a screen guide that guides the opening and closing movement of the screen.

2. Description of the Related Art Conventionally, for example, a barrier-free and horizontal winding type winding screen device disclosed in Patent Document 1 is known.
In the horizontal screen device disclosed in Patent Document 1, the screen guide for guiding the lower edge of the screen fed out from the winding shaft is placed on the lower rail of the building opening frame when the screen is wound around the winding shaft. In order not to remain, the screen guide is accommodated in a screen frame or a movable basket when the screen is wound, so that the screen device is made barrier-free.

  More specifically, the screen guide is configured by connecting a number of guide pieces long in one direction, and in this case, a number of engaging members provided along the lower edge of the screen are connected to the screen guide. In order to engage with the engaging groove provided on the upper surface of each of the guide pieces, a slit that forms the engaging groove when the guide pieces are connected is provided on the upper surface wall of each guide piece. Then, the gap generated between the slits of the connected guide pieces is made as small as possible to suppress the separation of the screen engaging member from the gap, and when the screen guide enters and exits the screen frame or the movable rod. Therefore, the guide piece is connected by a flexible wire member inserted into a pair of left and right holes penetrating the upper surface wall.

  However, as disclosed in FIG. 11B of Patent Document 1, a groove is formed on the lower surface of the base portion of the guide piece, and the groove extends over the lower rail provided at the lower portion of the screen frame. In the case of guiding the guide piece in a straight line, or directly as shown in FIGS. 3 and 4 of the same document, the guide piece is not directly guided by the lower rail of the lower part of the screen frame. Rather than inserting the wire member through the top wall far away from the base part of the guide piece and connecting the guide piece to the base part of the guide piece, that is, the traveling surface of the screen guide. Connecting a large number of guide pieces with a wire member or the like in a close part, for example, the lower side between the guide pieces is opened and the traveling becomes unstable, or foreign objects are sandwiched between the open guide pieces. Problem even without connecting postures of the guide piece itself posture and their guide pieces will be stabilized.

  Further, in connecting the guide pieces, as in Patent Document 1, when the guide pieces are connected by a wire member inserted through the upper surface wall that is largely separated upward from the base portion of the guide piece, the upper surface wall is provided with a screen. Since a slit for guiding the lower end is provided, it is necessary to insert a pair of wire members on the left and right sides of the upper surface wall to maintain a balance between the left and right connecting forces of the guide pieces by the wire members. When a large number of guide pieces are connected at the base portion, that is, a portion close to the traveling surface of the screen guide, it is not necessary to use a pair of wire members as described above, and the insertion portion on the base portion of the guide piece is flexible. This also stabilizes the orientation of the screen guide as compared to the case where the pair of wire members are used. Bets can be, moreover, the screen guide of the assembly process is also simplified as compared with the case of using the wire member.

  However, when a large number of guide pieces of the screen guide are connected by a wire member or a belt-like member at the base portion of the guide piece, that is, at a portion close to the traveling surface of the screen guide, the attachment attached along the lower edge of the screen. Even when trying to hold the joint member in the engaging groove on the upper surface of the screen guide, when the screen guide is curved to enter and exit from the opening of the lower end of the fixed frame or the movable rod, the adjacent guide pieces It is necessary to avoid the upper parts from colliding with each other. When the guide pieces are formed so as to avoid the collision, when the screen guide travels on a flat surface, the upper surface walls are separated between the guide pieces, and accordingly As a result, the slits on the upper surface wall are greatly separated from each other, so that the engaging member attached along the lower edge of the screen is secured to the engaging groove on the upper surface of the screen guide. Manner can not be engaged with and held.

JP 2004-346578 A

  The present invention has been made to solve the above-described problems, and its technical problem is that a screen guide that guides opening and closing movement of the lower end of the screen winds the screen around the winding shaft. In a barrier-free horizontal screen device that does not remain on the opening frame, the movement of the screen guide is further stabilized, and the engaging member attached to the lower edge of the screen is used as an engaging groove on the upper surface of the screen guide. It is an object of the present invention to provide a barrier-free lateral pulling roll screen device that is stably engaged and held.

  In order to solve the above-described problem, according to the present invention, a winding shaft is attached to a winding shaft between a fixed frame on one side of a screen frame and a movable rod that can be opened and closed by lateral pulling with respect to the fixed frame. A rotated screen is installed by supporting the winding shaft on one of the fixed frame and the movable rod, and supporting the tip of the screen led out from the winding shaft on the other, one of the fixed frame and the movable rod. A screen guide having one end fixed to the lower end portion thereof and the other end being curved into and out of an opening provided in the lower end portion of the other of the fixed frame and the movable rod, and provided on the upper surface of the screen guide In the barrier-free horizontal pulling roll screen device in which a large number of engaging members provided along the lower edge of the screen are slidably engaged and held in the engaging grooves along the extending direction of Characteristic composition Example was screen device is provided.

  The characteristic configuration described above is that the screen guide is configured by connecting a plurality of guide pieces, and each guide piece is placed on a base portion guided by a lower rail installed as a lower frame of the screen frame. And a short cylindrical portion formed by providing a side wall along both sides of the direction and an upper surface wall having a slit in the guide direction at the upper end of the side wall, and the guide direction on the base portion By providing an insertion portion of a flexible connecting strip toward the connecting portion, connecting a large number of guide pieces by insertion of the connecting row to the insertion portion, and by a row of slits provided in a short cylindrical portion in those guide pieces, The engagement grooves for slidably engaging and holding a number of engagement members provided at the lower edge of the screen are formed, and each guide piece is connected to the screen guide from the opening of the lower end of the movable rod or fixed frame. Come in and out In order to avoid contact of the end of the short cylindrical portion in the adjacent guide piece during bending, the side wall end in the short cylindrical portion is formed to be shifted inward and outward, and the short cylindrical shape in the adjacent guide piece is formed. The upper surface wall of the part is disposed at a position shifted in the advancing direction of the guide piece with respect to the base part, and the adjacent short cylindrical part rotates around the connecting part of the adjacent guide piece by the connecting strip. Sometimes, the upper corner of the end of the upper surface wall of the adjacent guide piece that sinks into the lower portion of the upper surface wall of one guide piece is cut obliquely, and conversely, the upper wall of the adjacent guide piece that approaches the upper portion of the upper surface wall at that time The lower corners of the end portions are also cut obliquely, and when adjacent guide pieces are not curved, the cut portions are formed so as to face each other with a narrow space therebetween.

  In a preferred embodiment of the lateral pulling roll screen device according to the present invention, the connecting strip for connecting a large number of the guide pieces is on a base portion of each guide piece and has a wide insertion extending between the pair of side walls. The screen guide is configured by forming a flexible strip member inserted through the portion and connecting guide pieces at both ends of the strip member to the end portions of the strip member.

  In another preferable embodiment of the roll screen device according to the present invention, the lower rail has a strip-like shape extending linearly, and is provided on the lower surface of the base portion of the guide piece constituting the screen guide. A concave groove is provided across the lower rail so that the lower rail guides the linear opening and closing movement of the screen by the movable rod.

  Furthermore, in another preferable embodiment of the roll screen device according to the present invention, a flat plate-like convex portion projecting to the adjacent guide piece side is connected to the lower surface of the base portion of each guide piece, and the connection by the connecting strip. A concave portion into which the convex portion is fitted when the adjacent guide piece is in a non-curved state, and the convex curve on the screen guide is prevented by fitting into the concave portion of the convex portion in the adjacent guide piece. Thus, it is possible to suppress partial floating of the screen guide.

  In the barrier-free horizontal roll screen device having the above-described configuration, the guide pieces are connected by connecting strips such as belt-like members at the base portions of a large number of guide pieces in the screen guide, that is, at a portion close to the traveling surface of the screen guide. When the screen guide is bent to enter and exit from the opening at the lower end of the fixed frame or movable rod, it is not only necessary to avoid the upper parts of adjacent guide pieces from colliding with each other, but also the screen. In order to stably hold the engaging member at the lower edge of the engaging member in the engaging groove on the upper surface of the screen guide, it is necessary to avoid the upper portions of the guide pieces from being separated from each other more than necessary.

  The upper surface wall of the short cylindrical portion of each guide piece in the screen guide is disposed at a position shifted in the advancing direction of the guide piece with respect to the base part, and the connection portion of the adjacent guide pieces by the connecting strip is the center. When the adjacent short cylindrical parts rotate with each other, the upper corners at the end of the upper surface wall of the adjacent guide piece that sinks into the lower part of the upper surface wall of one guide piece are cut diagonally, and conversely, When the lower corner of the end of the upper surface wall of the adjacent guide piece that approaches the upper part is also cut obliquely, when the adjacent guide pieces are not curved, the cut portions face each other diagonally through a narrow interval. The configuration thus formed is extremely effective for solving the above-described problems. In addition, the above configuration is designed to make the radius of the rotational movement path of the adjacent guide piece as small as possible when the screen guide is bent to enter and exit from the opening of the lower end of the fixed frame or the movable rod. This also makes it possible to reduce the cross-sectional shape of the receiving area of the screen guide provided in the fixed frame or the movable cage.

  As described above, according to the above guide screen, the simple guide that only improves the shape of the short cylindrical portion of the guide piece not only avoids the collision of the upper part of each adjacent guide piece, but also the screen guide moves on the flat surface. When traveling, it is possible to avoid the separation of the upper surface wall between the guide pieces, and the engagement member at the lower edge of the screen is stably engaged and held in the engagement groove on the upper surface of the screen guide. Even during the mutual rotation of the guide pieces, the upper surface wall of the adjacent guide piece is displaced up and down, and the movement of the upper surface wall of the screen guide is not hindered.

  According to the barrier-free horizontal roll screen device of the present invention described in detail above, the screen guide for guiding the opening and closing movement of the lower end of the screen remains on the building opening frame when the screen is wound around the winding shaft. In a non-barrier-free roll-up screen device, the movement of the screen guide is further stabilized, and the engaging member attached to the lower edge of the screen is stably engaged with the engaging groove on the upper surface of the screen guide. Can be retained.

It is the external appearance expansion perspective view which looked at the said guide piece from the other direction. It is an enlarged rear view of the guide piece.

  The drawings show an example of the implementation of the barrier-free horizontal roll screen device according to the present invention. As shown in FIGS. 1 and 2, in this screen device, a screen frame fixed to a building opening frame or the like is arranged between a pair of left and right opposing fixed frames 1 and 2 and between their upper and lower ends. A take-up shaft formed between an upper rail 3 and a lower rail 4 provided between a fixed frame 1 on one side and a movable rod 5 that can be opened and closed by lateral pulling with respect to the fixed frame 1. A screen 7 wound around 8 allows the fixed frame 1 to rotatably support the winding shaft 8, and the movable rod 5 has a mounting piece at the tip of the screen 7 led out from the winding shaft 8. It is attached by supporting it.

  The fixed frame 2 forms a receiving frame with which the movable rod 5 comes into contact when the screen 7 is stretched in the screen frame by the operation of the movable rod 5. At least the winding shaft 8 When a spring 8a for applying an urging force for winding the wound screen 7 is housed inside, the screen 7 is held in a stretched state. Is provided with a latch for temporarily holding them in an engaged state.

  One end of a screen guide 10 as described in detail below with reference to FIGS. 3 to 7 is fixed to the lower end of the fixed frame 1 that rotatably supports the winding shaft 8. The other end of the screen guide 10 is guided to the lower end of the movable rod 5 along the lower rail 4 and is formed so as to be curved in and out of the opening 5a provided at the lower end of the movable rod 5. It is made to be introduced upward into the movable rod 5 along the passage 5b.

  The screen guide 10 is constructed by connecting a large number of guide pieces 11 in one direction, and the screen guide 10 itself is arranged in an array on the upper wall 15 of the guide piece 11 as clearly shown in FIG. Is provided with an engaging groove 10a along the extending direction of the screen 7, and a plurality of engaging members 7a provided along the lower edge of the screen 7 are slidably engaged and held. When the screen 7 is guided in the storing direction, the screen guide 10 is introduced into the opening 5a at the lower end of the movable rod 5 at the same time as the screen 7 is wound up. This makes it possible to make the lower frame of the frame barrier-free. As the engaging member 7a provided at the lower end edge of the screen 7, it is desirable to use a half of a joining fastener such as a cloth in which small pieces meshing with each other are attached to a pair of cloth tape edges as shown in FIG.

  In the embodiment shown in FIG. 1, the fixed frame 1 is configured to also serve as a winding box for the screen 7, and the winding shaft 8 is supported in the fixed frame 1. Can be supported in the movable rod 5 and the tip of the screen 7 led out from the take-up shaft 8 can be held on the fixed frame 1 via the attachment piece. In this case, one end of the screen guide 10 is fixed to the lower end of the movable rod 5, and the other end of the screen guide 10 is guided along the lower rail 4 to the lower end of the fixed frame 1. From the opening provided in the part, the inside is curved and moved in and out.

  As shown in FIGS. 4 to 7, each guide piece 11 in the screen guide 10 is on a base portion 13 guided by the lower rail 4 as a lower frame of the screen frame, along both sides in the guide direction. A short cylindrical portion 12 formed by providing a pair of side walls 14 and an upper surface wall 15 at the upper end of the side walls 14 and having the slit 16 in the guide direction at the center thereof is provided. The base portion 13 is provided with an insertion portion 17 through which the flexible connecting strip 18 is inserted in the guide direction, and a large number of guide pieces 11 are connected by inserting the connecting strip 18 into the insertion portion 17.

It is formed.

  Each guide piece 11 makes mutual contact between the front and rear end portions of the short cylindrical portion 12 in the adjacent guide piece 11 when the screen guide 10 is bent when the screen guide 10 enters and exits from the opening 5a at the lower end portion of the movable rod 5. As shown in FIGS. 4 to 6, the front and rear end portions 14a and 14b of the side wall 14 in the short cylindrical portion 12 are shifted inward and outward, specifically, the front end portion 14a side is inward. The rear end portion 14b is formed so as to overlap the outside. Further, when the adjacent guide piece 11 performs the above bending, it is possible to prevent the adjacent guide pieces from rotating excessively, thereby enabling the rotation within a certain range, and smoothing the above bending within an appropriate range. Therefore, when the adjacent guide piece 11 rotates to the front end portion 14c of the rear half portion of the side wall formed by shifting the position outside the side wall 14, the adjacent guide piece 11 A contact surface that contacts the rear end 14b of the side wall is formed.

  On the other hand, the upper surface wall 15 of the short cylindrical portion 12 in the adjacent guide piece 11 is disposed at a position shifted in the advancing direction of the guide piece 11 with respect to the base portion 13 as can be seen from FIGS. However, as a result, when the short cylindrical portions 12 adjacent to each other around the connecting portion 18a of the adjacent guide piece 11 by the connecting strip 18 rotate relative to each other, the upper surface wall of the short cylindrical portion 12 of the adjacent guide piece The 15 opposing ends will move up and down relative to each other.

When the adjacent guide piece is not curved, the end 15b of the upper surface wall 15 of the adjacent guide piece 15 that approaches the upper part of the 15 is cut off at a lower corner thereof, when the adjacent guide pieces are not curved. 15d are formed so as to face each other diagonally through a narrow interval D, and when the short cylindrical portion 12 rotates, the cut surface 15d faces close to the upper surface wall 15 of the adjacent guide piece. Is formed.

  The lower rail 4 has a strip-like shape extending linearly on the lower frame of the building opening in order to make the building opening where the screen device is installed barrier-free, and is fixed to the floor surface. In order to move the screen guide 10 along with it, the guide piece 11 constituting the screen guide 10 has a recess straddling the lower rail 4 on the lower surface of the base portion 13. A groove 19 is provided to be guided over the lower rail 4.

  Further, the connecting strip 18 for connecting a large number of the guide pieces 11 can be held on the lower rail 4 near the center of gravity in the vertical direction of the guide pieces, such as directly above the base portion 13 of each guide piece 11. The state is effective for stably guiding the screen guide 10 by the thin lower rail 4, and in the lower part of the short cylindrical portion 12 in the guide piece 11, it is shown in FIGS. 4 to 7. Thus, the attitude | position of the screen guide 10 can be stabilized as a wide thing extended between a pair of side wall 14,14. Further, the connecting strip 18 inserted through the insertion portion 17 can be formed as a wide one by a flexible strip-shaped member made of synthetic resin, thereby maintaining the balance of the left and right connecting forces of the screen guide 10. It is also possible to stabilize the posture so as not to bend left and right. In addition, the strip | belt-shaped member as the said connection strip | line 18 can comprise the screen guide 10 simply by connecting the guide piece 11 located in the both ends to the edge part of this strip | belt-shaped member with an eyelet etc. FIG.

  Further, as clearly shown in FIG. 5 and FIG. 6 and the like, the lower surface of the base portion 13 of each guide piece 11 has a flat plate-like convex portion 20 protruding toward the adjacent guide piece 11 side, and the above connecting strip. 18 and the concave portion 21 into which the convex portion 20 is inserted when the adjacent guide piece 11 is in a non-curved state by the connection by 18, and as shown in FIG. 3, the concave portion 21 of the convex portion 20 in the adjacent guide piece 11. The screen guide 10 is prevented from curving upward so that the guide by the lower rail 4 is stabilized.

Next, the support of the upper end of the screen 7 by the upper rail 3 will be described. As can be seen from FIGS. 1 and 2, an inner rail 25 for guiding the opening and closing of the upper end of the screen 7 is provided in the upper rail 3. The protrusions 25a on both outer side surfaces of the inner rail 25 are supported by a pair of receiving step portions 3a provided on the inner side surface of the upper rail 3, and the inner rail 25 is extended in the direction in which the screen 7 is stretched. An engagement groove 25b for engaging a plurality of engagement members 7b provided at the upper end edge of the screen 7 is opened along the screen, and the engagement rail 7b is engaged with the engagement groove 25b, whereby the inner rail 25 is screened. 7 is suspended so that it can be opened and closed.
