Further, the rail member has a skeleton having an H-shaped cross section, is a cross-sectional hollow polyhedral shape in which both side surfaces and upper and lower surfaces are formed in a planar shape, and has a dovetail-shaped guide groove formed in both side surfaces, It is also described that a plurality of runners, which are formed along the longitudinal direction on the upper and lower surfaces facing each other and can be connected to the upper end portion and the lower end portion of the shielding sheet, have cross-sectional dovetail slide grooves. Yes. In the drawings described in this document, the shielding sheet is opened and closed in the left-right direction.

  In this shielding structure, since the runner can run along the slide groove, the shielding sheet can be smoothly opened and closed in the left-right direction. However, in the construction site, it is desired that the shielding sheet can be opened and closed not only in the left-right direction but also in the vertical direction.

  In Japanese Patent Laid-Open No. 11-050666 (Patent Document 3), a seat is suspended in a vertically movable manner between two rail frames standing parallel to each other via a pulley on the top of the structure. The lower end of the seat is rotatably wound around the drum below the rail frame, and guides are attached to both ends of the seat with a space in the vertical direction, and the guides with springs are inserted into the guide rails so as to be movable up and down. A sheet spreading device is disclosed that can wind or unwind the sheet with a drum while applying tension in the direction.

  However, in this apparatus, since it is necessary to open and close the sheet by winding or rewinding the sheet with a drum, it becomes a large-scale apparatus and cannot be used easily and easily at the construction site. In particular, it is often difficult to arrange a rotatable drum in a high-rise part of a building.

Thus, the temporary member 15 and the attachment member 24 can be fastened to the pole 1.

  As shown in FIGS. 2 and 9, a plurality of runners 31 can run in the slide groove 3 of the pole 1 while being connected to or connected to both sides of the opening / closing sheet 55 at intervals in the vertical direction. It is arranged. The runner 31 includes a traveling unit 32 (a pair of rollers 32a, a shaft portion 32b that rotatably supports the pair of rollers, and a pair of rollers 32a that can travel on the traveling surface of the slide groove 3 of the pole 1. A support frame portion 32c for rotatably supporting the shaft portion 32b between them, and the travel unit (support frame portion) can be rotated along the axis (or centered on the axis) and cannot be removed. The attached rotating member (rotating shaft member) 33, the ring-shaped swinging member 34 swingably attached to the rotating member, the swinging member attached to the ring-shaped swinging member, and the seat 55 And an attachment unit 35 that can be clamped or clamped. Further, the roller and the support frame portion are made of plastic. Further, the mounting unit 35 is engaged with the receiving member 36 on which the ring-shaped swinging member 34 is swingably mounted and the side portion of the opening / closing sheet 55 can be disposed, and is pressed. Along with this, the clamping member 44 capable of clamping the sheet 55 at the front end portion, and attached to the receiving member 36 so as to be rotatable (openable / closable), and the clamping pressure accompanying the rotation (opening / closing operation). And a pressing member 49 capable of pressing the member 44.

  More specifically, as shown in FIGS. 10 and 11, the receiving member 36 is formed with a peripheral wall having a low height except for one end portion, and has a boat-like shape as a whole. , A standing wall 37 formed at one end, a rectangular mounting hole 38 formed from the bottom to the bottom of the standing wall, and both sides of the standing wall 37 are cut out in a U-shape. A notch (or notch recess) 39 on which the rocking member 34 can be swingably fitted and mounted, and both sides closer to the tip side (the other end or front side) than the mounting hole 38 The support part 40 formed in the shape of a side wall having a low height at the part, the side wall part 41 having a large height formed on both side parts on the tip part side (front side) than the support part, and the both side walls And a shaft support hole 42 formed in the portion. In order to increase the strength of the receiving member 36, a rib portion 43 extending in the longitudinal direction is formed at the bottom of the receiving member 36.

  The pinching member 44 is formed of a leaf spring material, and has a form in which the other end portion protrudes from the one end portion toward the pressing member 32 and is bent or bent toward the receiving member 36 at the tip end portion. Yes. That is, a pressed part 44a formed in the front area from the engaging part with the receiving member 36, and formed in the front area from the pressed part and curved or bent in a direction approaching the pressing member 32 side. The inclined wall portion 44b, the extending portion 44c extending in parallel with the pressed portion 44a from the tip portion of the inclined wall portion, and the receiving member 36 side bent or descends from the tip portion of the extending portion. And a pressing wall 44d.

  The pinching member 44 is formed at one end, and is attached to the mounting hole 38 of the upright wall 37 and can be engaged with the peripheral wall of the mounting hole, and extends to both sides of the one end. And a support protrusion 46 that can be supported by the support 40 and a tooth-shaped pinching portion (pressing wall) 47 formed on the pinching wall 44d at the tip (the other end) side. ing. The engaging portion between the receiving member 36 and the pinching member 44 is formed by engaging the fulcrum protrusion 45 mounted in the mounting hole 38 of the standing wall 37. The pinching member 44 is formed with a rib portion 48 extending in the longitudinal direction (a rib portion extending in the longitudinal direction across the inclined wall portion 44b from the pressed portion 44a to the extending portion 44c).

  The pressing member 49 has a shell-like shape (a shape curved in the width direction or the left-right direction around the center in the width direction) as a whole, and at one end, the receiving member 36 side ( A pressing wall 50 that bulges (below) and curves is formed to be inclined or bent toward the receiving member 36 side. On both side portions of the pressing wall 50, a shaft support portion 51 that can be rotatably mounted in a shaft support hole 42 of the receiving member 36, and the clamping member 44 are attached in accordance with a closing operation around the shaft support portion. A pressing portion 52 that can be pressed, and the pressing portion 52 is formed by a bulging portion (or a curved portion) at the tip of the pressing wall 50. In order to restrict the pressing wall 50 and the pressing member 49 from rotating in the opening direction (release direction) in the closed state, the pressing force by the pressing member 49 is maintained. The portion 52) is located on one end side (the standing wall 37 side) of the shaft support portion 51. That is, the pressing wall 50 is inclined to one end side (the standing wall 37 side) as it goes to the receiving member 36 side.

  In such a mounting unit 35, the fulcrum protrusion 45 of the pinching member 44 is inserted into the mounting hole 38 of the standing wall 37 of the receiving member 36, and the support protrusion 46 of the pinching member 44 is inserted into the support 40 of the receiving member 36. Since the supporting portion 40 is positioned slightly above the inner wall of the opening upper portion of the mounting hole 38 (on the pressing member 49 side), the pressing member uses the engaging portion of the fulcrum protrusion 45 in the mounting hole 38 as a fulcrum. Forty-nine pressing walls 50 are lifted. In such a state, when the shaft support portion 51 of the pressing member 49 is mounted in the shaft support hole 42 of the both side wall portions 41 of the receiving member 36 and the pressing member 49 is closed, the pressing member 49 is turned (closed). Accordingly, the receiving member 36 can be pressed by the pressing wall 47 of the pressing member 44 while the pressed portion 44 a of the pressing member 44 is gradually pressed by the pressing portion 52. Since the pressing wall 50 is inclined, when the distal end portion of the rotating pressing portion 52 passes through the lowermost portion, the distal end portion (pressing portion 52) of the pressing portion 52 is closer to the standing wall 37 than the shaft support portion 51. The closing operation by the pressing member 49 is completed elastically. Therefore, the sheet 55 is disposed between the receiving member 36 and the pinching member 44, and the pressing member 49 is tilted toward the receiving member 36, whereby the sheet is formed between the receiving member 36 and the pinching wall 47 of the pressing member 44. 55 can be firmly clamped or clamped, and the receiving member 36 and the clamping wall 47 of the clamping member 44 can form a pair of clamping parts. Further, by rotating the pressing member 49 in the reverse direction from the closed state to return it to the open state, it is possible to easily release the pinching or pinching of the seat 55. Therefore, the attachment work to the seat 55 can be performed smoothly, and the clamping pressure or the clamping position of the seat 55 can be easily corrected. Furthermore, when such a clamping pressure or clamping mechanism is used, it is not necessary to form a mounting hole or a reinforcing part (eyelet part) for reinforcing the mounting hole in the seat 55. Therefore, the runner 31 can be movably disposed on the pole 1 and can be easily and efficiently attached to the seat 55, and an open / close structure (open / close shield structure) can be formed by a simple operation.

  An opening / closing mechanism for opening / closing a section formed by the pole 1 and the temporary member 15 with the opening / closing sheet 55 includes the pulley 25 and the opening / closing operation string 60. That is, as shown in FIG. 9, the upper part of the opening / closing sheet 55 is formed in a bag stitch shape, and the temporary member 15 is inserted into the hollow bag stitch portion 55a. Further, as shown in FIG. 5, the opening / closing sheet 55 is formed with fold-fold portions 55 b extending in the horizontal direction at intervals in the vertical direction, and annular eyelet portions on both sides of the fold-fold portion 55 b of the opening / closing sheet 55. 56 is formed, and the lower part of the opening and closing sheet 55 is formed in a bag-sewn shape, and a weight 57 (such as a metal chain) extending in the lateral direction is attached to the hollow bag-sewn portion so as not to fall off. The opening / closing sheet 55 is formed with folds 58 extending in the horizontal direction at intervals in the vertical direction.

  In order to open and close such an opening / closing sheet 55 in the vertical direction, the end portions of the opening / closing operation string 60 are attached (or fixed) to the lower portions of both sides of the opening / closing sheet 55 so that they cannot be removed, and each string 60 is connected to the opening / closing sheet. In a state in which the eyelet portion 56 is inserted through both sides of 55, it is hung on each pulley 25 on both upper side portions, and a string 60 from one pulley 25 is hung on the other pulley 25. Therefore, when the two strings hung on the other pulley 25 are pulled downward, the lower part of the opening / closing sheet 55 is lifted to release the section, and when the pulling operation is released, the lower part of the opening / closing sheet 55 is lowered. The compartment is closed. In addition to the pulley 25 and the opening / closing operation string 60, the opening / closing mechanism also includes a retaining part (fixed part) for the string 60 at the lower part of the opening / closing sheet 55 and an eyelet part 56 through which the string 60 can be inserted.

  Further, cover members 59 for concealing the gap between the pole 1 and both ends of the opening / closing sheet 55 are attached to both sides of the opening / closing sheet 55 so as to extend in the longitudinal direction.

  Such an opening / closing structure (opening / closing type shielding structure) can fasten the support (support) 13 and the scaffold member 14 with the clamp mechanisms 11 and 12, and the support (support) 13 and the pole 1 with the clamp mechanism 10. Can be concluded. In particular, by using the clamp mechanism 10 with the L-shaped angle member 9 interposed, a construction space can be secured and a scaffold can be formed. Further, the partition can be formed by temporarily connecting the temporary member 15 by being connected to the pole 1 by a connecting mechanism. In particular, the height position can be fixed by screwing the fastening nut 23b to the lower screw member 23a of the slide member 22 slidable in the guide groove 2 of the pole 1, and the upper screw portion 23a and the temporary member 15 can be fixed. The temporary member 15 and the attachment member 24 can be fastened to the pole 1 by using the notch 20, the slit-like notch 28 of the attachment member 24, and the fastening nut 23b that can be screwed into the screw member 23a. Thus, the compartment can be easily and easily formed with a simple structure. Moreover, since the runner 31 is disposed in the slide groove 3 of the pole 1, the opening / closing sheet 55 arranged in the compartment can be smoothly opened and closed in the vertical direction. Further, since the travel unit 32 of the runner 31 is disposed in the slide groove 3 of the pole 1 and the mounting unit 35 of the runner 31 is configured by a clamping mechanism, the runner 31 can be attached to the opening / closing seat 55 even in a narrow construction space. 31 can be easily attached or connected. Furthermore, the slide member 4 (slide member for forming a scaffold with the support column and the scaffold member) and the slide member 22 (sliding member for connection with the temporary member 15) that can be slidably mounted in the guide groove 2 are shared. It is also possible.

  Therefore, even during repair work on the outer wall, etc., the scenery can be seen even if the window is opened, and fresh air can be taken in. Moreover, since the upper part of the opening-and-closing sheet | seat 55 is attached to the temporary member 15, and it can connect to the runner 31 at both sides, the shielding sheet | seat 55 does not fly up or winds greatly by a wind. Furthermore, since the contact portion of the runner 31 that comes into contact with the erection member 15 as it travels is formed of plastic, even if the shielding sheet 55 is shaken by wind or the like and the runner 31 collides with the slide groove 3, the runner 31 It is silenced by plastic and can suppress the generation of noise. The pole 1 and the erection member 15 can be easily connected and disconnected (that is, assembled and disassembled), and a skeleton (open / close shield structure) including the open / close shield sheet 55 can be easily formed. Moreover, the frame | frame which has a scaffold in the vertical and horizontal direction with respect to the outer wall of a building with the some support | pillar 13 and the scaffold member 14 can be constructed | assembled, and the pole 1, the construction member 15, and each division can be constructed | assembled easily. Furthermore, since the pole 1 has a vertically and horizontally symmetrical structure, it is possible to improve assembly efficiency without forming a section by mistakenly facing the pole 1.

[Pole]
The poles need only be arranged to face each other at a predetermined interval according to the type of building or structure, and may be arranged in the horizontal direction. Can be disposed). The pole may be made of metal, for example, iron or stainless steel, but is usually made of aluminum or aluminum alloy. When formed by aluminum die casting, it is lightweight and has high mass productivity.

  The cross-sectional shape of the pole need not be a symmetric shape, but it is advantageous that the cross-sectional shape is a symmetric shape in order to improve workability. Further, the cross-sectional shape of the pole may be solid, but usually it is often hollow from the viewpoint of weight reduction. The cross-sectional shape of the pole can be formed symmetrically with respect to the slide groove or the guide groove. For example, the cross-sectional shape may be a cylindrical cross-section, an H-shaped cross-section, etc. For example, it may have a cross-sectional hollow polygonal shape (square, hexagonal, octagonal shape, etc.), a cross-sectional hollow circular shape, a cross-sectional hollow elliptical shape, etc., particularly a cross-sectional polygonal shape (cross-sectional hollow square shape, etc.). For example, the cross-sectional shape of the pole is at least two side walls (two side walls extending parallel to the direction perpendicular to each other) extending in a direction perpendicular to each other, particularly four side walls (two side walls parallel to each other, and orthogonal to these side walls. In many cases, the corners of these cross-sectional polygons may be chamfered planarly or curvedly. In a preferred form, the pole is formed in a cross-sectional polyhedron shape having front and rear side walls and left and right side walls in a state of being arranged upright.

  An end stopper is usually attached to both ends of the slide / guide groove of the pole in order to prevent the runner / slide member from falling off.

  On the opposing walls of the pole that can face each other (for example, the opposing walls of the left and right side walls in the standing state), a slide groove is formed in which the runner can run or move along the longitudinal direction. This slide groove usually has a cross-sectional dovetail shape in which the width of the deep part is wider than the width of the opening part in order to prevent the runner from being detached. The slide groove may be formed on opposing walls (at least opposing walls) that can face each other. When the open / close structure is formed adjacent to each other in the horizontal direction / vertical direction, both the left and right sides in the standing state / horizontal state are provided. Two opposing walls of the wall / upper and lower side walls (inner walls of the left and right side walls / inner walls of the upper and lower side walls) and both side walls of the back of the facing wall (outer walls of the left and right side walls / outer walls of the upper and lower side walls) You may form in.

  At least one engaged convex portion is formed on the pole for easily attaching a temporary member or the like. This engaged convex portion is a side wall adjacent to the opposing wall in which the slide groove is formed (particularly, a side wall extending in a direction orthogonal to the opposing wall), for example, the front and rear side walls in a standing state / horizontal state. It can be formed on at least one side wall (front side wall, rear side wall, or both front and rear side walls).

  A guide groove is not necessarily required for the pole. In order to adjust the mounting position of a temporary member or the like, a plurality of engaged protrusions, for example, 2 to 5 (preferably 2 to 3) are provided at intervals in the longitudinal direction. ) Degree of engaged protrusions may be formed. The shape of the engaged convex portion is not particularly limited as long as the engaging portion of the temporary member and the engaging concave portion of the mounting member can be engaged, and may be formed of a curved body such as a bowl shape. It can be formed of a rod-like body (for example, a screw member having a screw portion at a free end and a shaft portion). The engaged convex portion is formed at an appropriate position of the pole to which a temporary member or the like is attached, usually one section, and can be formed at least at the upper portion of the pole, and is not necessarily required at the portion of the pole corresponding to the lower portion of the one section. Absent.

  Further, in order to adjust the mounting position of the temporary member, the pole includes a side wall adjacent to the opposing wall (particularly, a side wall extending in a direction perpendicular to the opposing wall), for example, both the front and rear side walls in a standing / horizontal state. It is preferable to form a guide groove along the longitudinal direction on at least one side wall (front side wall, rear side wall, or both front and rear side walls). The guide groove only needs to be able to slide or slide a slide member having a width larger than the opening of the guide groove. Usually, in order to prevent the slide member from being detached, the guide groove has a U-shaped section with a narrow opening. In many cases, it has a dovetail shape in cross section. The slide member may be screwed with a rod-shaped screw portion to form a screw member as an engaged convex portion, or the rod-shaped screw portion is welded to form a screw member as an engaged convex portion. May be. A plurality of, for example, about 2 to 5 (preferably 2 to 3) engaged protrusions (screw members or the like) may be formed on the slide member at intervals in the longitudinal direction.

  In a preferred embodiment, the pole has a slide groove formed on two side walls parallel to each other (a side wall located opposite to each other, a planar side wall), and two side walls extending parallel to each other in a direction perpendicular to the side walls. And a guide groove formed on the opposite side wall and the planar side wall.

  The structure of the slide groove is not particularly limited as long as the runner can run or move, and often has a U-shaped cross-section with a narrow opening, and has a cross-shaped dove-like shape.

  The pole may include a stopper that restricts the travel of the runner at at least one end. If such a stopper is provided, the runner will not fall out of the slide groove even if a strong wind acts on the shielding sheet or the like. Further, a stopper for preventing the slide member from falling off may be provided.

[Temporary members]
The temporary member may be temporarily connected to the pole in the horizontal direction, may be temporarily set at an interval in the vertical direction, and usually has a bar shape. Similar to the pole, the temporary member may be made of metal, for example, iron or stainless steel, but may be usually made of aluminum or an aluminum alloy. The shape of the temporary member may be a cylindrical cross section like the pole, but is usually a polygonal cross section (or polyhedron), and the pole may be a solid cross section, but it is lightweight. In general, from the viewpoint of conversion, it is often hollow. For example, the cross-sectional shape of the temporary member may be the same shape as the pole, or may be a polygonal shape such as a quadrangular shape, a pentagonal shape, a hexagonal shape, or an octagonal shape. The cross-sectional shape of a preferable temporary member is often a quadrangular shape or the same shape as the pole.

  The temporary member includes an engaging portion that can be engaged with an engaged convex portion of the pole, and the form of the engaging portion can be engaged according to the form of the engaged convex portion. For example, a notch portion (a U-shape, a U-shape, a V-shape, etc.) that can be mounted on an engaged convex portion (such as a shaft portion of a screw member) from the upper side or the left-right direction. Form). The engaging portion can be engaged and adjusted in length with respect to the engaged convex portion (such as the shaft portion of the screw member), for example, upward with respect to the engaged convex portion (such as the shaft portion of the screw member). It may have a T-shaped form with a wide notch that is wider than the entrance and extends deeper in the lateral direction.

  The temporary member may be formed of a single member or a plurality of members. For example, an engaging member (or a connecting member) that can be engaged with an engaged convex portion (such as a shaft portion of a screw member) may be attached or attached to both ends of the temporary member. More specifically, the temporary member can be composed of a temporary member main body and a connecting member that can be connected to or attached to both ends of the temporary member main body, and the connecting member (joint portion) is connected to the temporary member main body. A connectable connecting portion, an extending portion extending from the connecting portion, and a notch portion (engaging portion) formed in the extending portion and engageable with an engaged convex portion (screw member or the like). ).

  The temporary member main body is usually formed in a hollow cross-sectional shape (hollow cylindrical shape), for example, a cross-sectional hollow polygonal shape, and firmly attached to and connected to the temporary member main body at both ends of the temporary member main body. For this reason, a hollow polygonal shape corresponding to the cross-sectional shape of the temporary member main body or a polygonal piece-like (cross-sectional U-shaped) connecting portion (connecting member) corresponding to the opposing wall of the temporary member main body can be connected. This connecting member may be attached to the inner wall or the outer wall of the temporary member body having a hollow polygonal cross section. In many cases, the connecting portion is usually attached and connected to both ends of the temporary member body. Moreover, in order to attach a connection part (connection member) with respect to a pole immovably, it is preferable to have a wall surface which can surface-contact with a pole. Moreover, the extension wall should just extend from a connection part (connection member), and may extend from the side edge of a connection part. An engaging portion that can be engaged with an engaged convex portion (such as a shaft portion of a screw member) can be formed on the extending wall, and the engaging portion is an engaged convex portion (an axial portion of the screw member). Etc.), and may be a U-shaped or U-shaped notch, but usually, at the entrance and the deep part of the entrance as described above. A T-shaped notch having a horizontally long notch that extends (or extends) in the direction of both sides (lateral), and at least one side (or both sides) of the horizontally long notch in the T-shaped notch And a notch portion provided with a recessed portion that accommodates or drops an engaged convex portion (such as a shaft portion of a screw member).

  Cross-sectional hollow polyhedron shape having a H-shaped cross-section (hollow cross-section polygonal shape) has high strength even if it is hollow, and is useful for forming a framework (such as a scaffold for repairing or reforming the outer wall of a building). It is. Therefore, the temporary member may be formed of the pole. FIG. 12 is a schematic exploded perspective view showing another example of a temporary member in the opening / closing structure of the present invention. In addition, the same code | symbol is attached | subjected and demonstrated to the member which is common in the said FIG.

  In this example, the temporary member includes a temporary member main body corresponding to the pole 1, a U-shaped connecting portion 17 slidably mounted in the slide groove 3 (or guide groove 2) of the temporary member main body, An extending wall 19 that bends and extends from the side edge of the connecting member is provided, and the extending wall can be engaged with an engaged convex portion (such as a shaft portion of the screw member). A joint portion (T-shaped cutout portion) 20 is formed. A connecting portion 17 having a U-shaped cross section is slid and attached to the slide groove 3 (or guide groove 2) of the temporary member body 1, and the U-shaped cross section of the connecting portion 17 is attached to the extended wall portion 2b of the temporary member body 1. In a state where the extension portion 17a is engaged or mounted, the extension portion 17a having a U-shaped cross section and the transverse wall 1a of the temporary member main body 1 are penetrated by a rod-shaped bolt (bar screw) 18a, and the thread portion of the rod-shaped bolt 18a is inserted. By screwing the nut 18b, the temporary member body 1 and the connecting portion 17 can be fastened to form a temporary member.

[Mounting member]
The pulley 25 may be directly attached to the pole and / or temporary member. However, in order to facilitate the attachment operation, the attachment member 24 provided with the pulley 25 is often attached to the pole and / or temporary member. . Further, the means for attaching the attachment member to the pole and / or the temporary member is not particularly limited. However, in order to facilitate the attachment operation, the attachment member includes an engagement recess that can be engaged with the engaged protrusion. ing.

  The attachment member only needs to be able to attach a pulley to the pole and / or temporary member, but usually includes a side wall to which the pulley can be attached, and a notch formed at the tip of the side wall, The notch is formed on an extended engagement wall (extension engagement wall extending in the forward direction) extending from the side wall in an upward direction with respect to an engaged protrusion (such as a shaft portion of a screw member). You may form so that mounting | wearing is possible from the left-right direction (especially left-right direction). The notch may be a recess (slit recess or slit notch), and a drop part (U-shaped recess or the like) 28a formed at the back of the slit notch is not necessarily required. However, by forming the drop portion 28a, it is possible to increase the degree of engagement between the attachment member and the engaged convex portion (such as the shaft portion of the screw member) and prevent the attachment member from falling off. Moreover, in order to attach stably, the said attachment member may be bent from the said side wall, and may have a latching wall (upper wall) which can be latched with respect to the upper wall of a temporary member. Although the pulley can be attached to an appropriate position of the attachment member, usually, in order to improve the appearance, the pulley is attached to the side wall (opening / closing sheet 55 side) as a shielding wall, and the pulley is often concealed by the side wall. The attachment member (or pulley) can usually be attached to the top of the pole for opening and closing the compartment. The distal end portion of the extended engagement wall may be bent or curved outward in order to prevent the attachment member from dropping from the engaged convex portion (screw member or the like).

  Various coupling means such as a clamp mechanism may be used for the coupling mechanism for coupling the pole and the temporary member. From the viewpoint of simplicity of the coupling operation, the engaged convex portion of the pole Fastened to the engaged convex part with the engaging part (T-shaped notch part, etc.) of the temporary member engaged with the engaging concave part (slit-like notch part, etc.) of the mounting member. It is advantageous to fasten a member (such as a fastening nut).

  In particular, the height position of the temporary member may be adjusted by forming a plurality of engaged protrusions in the height direction of the pole as described above, but the height position of the temporary member can be easily adjusted. Therefore, the coupling mechanism includes a slide member (positioning member) that can be slidably mounted in the guide groove, and a plurality of engaged protrusions (screw members) formed at intervals in the longitudinal direction of the slide member. And a fastening member (fastening nut or the like) that can be screwed to each engaged convex portion (screw member or the like).

  The slide member is often a plate-like member that is wider than the opening width of the guide groove, and the slide member includes at least two engaged convex portions (screw members or the like) spaced in the longitudinal direction. Are often formed integrally. That is, the pole and the slide member can be firmly fastened by screwing a fastening nut into an appropriate engaged convex portion (particularly, a lower screw member) among a plurality of engaged convex portions of the slide member. It is. Further, the engagement portion (notch portion) of the temporary member and the attachment member are attached to the shaft portion of an appropriate engagement portion (particularly, the upper screw member) among the plurality of engagement portions of the slide member. A temporary member is attached to the pole by mounting a mating recess (slit-shaped notch) and fastening a fastening member (screw member with a fastening nut) to an engaged projection (screw member or the like). And the mounting member can be firmly fastened. A plurality of engaged protrusions (screw members and the like), for example, about 2 to 5 (preferably 2-3) engaged protrusions (screw members and the like) may be formed on the slide member.

  A temporary member can be connected to the pole in both the left and right directions. FIG. 13 is a schematic perspective view showing the connection of the temporary member in the lateral direction in the opening / closing structure of the present invention. In this example, the attachment of the attachment member having the pulley to the pole is not shown. In this example, a slide member 22 having two screw members 23a is slidably mounted in the guide groove 2 of the pole 1, and a fastening nut 23b is screwed to the lower screw member 23a so as to be temporarily attached to the pole 1. The member 15 is fastened. Further, a T-shaped cutout portion 20 of the temporary member 15 similar to the above is mounted on the shaft portion of the screw member 23a at the upper portion of the fixed slide member 22, and is displaced or displaced by the wall surface in surface contact with the side wall of the pole 1. In a state where the rotation is restricted, the temporary member 15 extends in one direction (right lateral direction in the figure). Further, a temporary member 65 having a structure similar to that of the temporary member 15 extends in the other direction (left lateral direction in the figure). That is, the temporary member 65 includes a temporary member main body 66 having a hollow quadrangular cross section, a U-shaped connecting portion 67, a screw 68 for attaching the connecting portion to the temporary member main body 66, and a connecting member 67.

[runner]
As long as the runner can move and run smoothly in the slide groove, runners of various structures can be adopted as well as a specific structure. Usually, the runner can run along the slide groove of the pole, and An attachment unit (a connection part (or a connection part) that can be connected to or connected to both sides of the sheet) and is attached to the opening / closing sheet so as to be pivotable and swingable.

  The traveling unit usually has a roller portion (particularly a pair of roller portions) that can travel in the slide groove, a support shaft portion that pivotally supports the roller portion, and a rotation of the support shaft portion. A support portion (support frame portion) that is supported to be swingable is provided, and this support portion can pass through the slide groove (opening portion, passage) of the pole. The support portion may support, for example, a support shaft portion between the pair of roller portions or a support shaft portion extending from both side portions of the pair of roller portions so as to be rotatable or swingable.

  In many cases, the attachment unit is attached to the traveling unit so as to be rotatable and swingable, and the traveling unit and the attachment unit may be coupled by a linear coupling member such as a chain. In a preferred embodiment, a rotating member and a swinging member are interposed between the traveling unit and the mounting unit. That is, a rotation member is attached to the lower part of the support part (or support frame part) so as to be unmovable in the circumferential direction around the axis of the traveling unit (support part or support frame part), A swinging member is attached to the rotating member, and a mounting unit is swingably attached to the swinging member. When the rotation member is attached to the traveling unit, the attachment unit can be rotated in the circumferential direction, so that the seat attachment efficiency by the attachment unit can be improved. The form of the rotating member may be a shaft-shaped or rod-shaped rotating shaft member.

  In order to further improve the mounting efficiency of the mounting unit, a swinging member is swingably interposed between the rotating member and the mounting unit. For example, the swinging member may be mounted so as to be swingable using a through hole formed in the lower portion of the rotating shaft member. The rocking member may normally have a ring shape. The form of the ring-shaped rocking member is not particularly limited, and may be a polygonal frame shape or the like, but is usually a circular frame shape, an elliptical frame shape, or a square frame shape in many cases.

  The runner may be made of metal or plastic, but in order to improve the noise reduction, the contact portion (for example, the roller portion and the support portion) of the runner with the pole is made of plastic (for example, aromatic polyester resin, polyamide system). Resin, polycarbonate resin, polyphenylene ether resin, polysulfone resin and other strong plastics) are preferable.

  In addition, the preferable runner attachment unit can attach the side part of an opening-and-closing sheet | seat simply and easily by pinching pressure or a pinching function. If the clamping pressure or the clamping function is used, the sheet can be easily and easily attached without forming the mounting hole and the reinforcing portion around the mounting hole. Further, the attachment position with respect to the seat can be easily and easily adjusted by using the clamping pressure or the opening / closing operation of the clamping mechanism.

  The attachment unit having a clamping pressure or a clamping function includes, for example, at least a pair of clamping parts (or clamping parts) that are biased by a spring from the opening direction to the closing direction and can clamp or clamp the opening and closing sheet. ing. The mounting unit is composed of, for example, a pinching or clamping member in which a pair of clamping members are biased in the closing direction, for example, a pinching or clamping member called a clothespin, a double clip, or the like. May be.

  The mounting unit is normally engaged with the receiving member to which the rocking member can be attached and the sheet can be arranged (accepting the sheet), and the receiving member (for example, one end is engaged), And a pinching member capable of pinching the sheet at the front end portion when pressed, and a pivotable (openable and closable) attached to the receiving member, and the pinching pressure associated with the pivoting (opening and closing operation). You may provide the pressing member which can press a member to a receiving member direction.

  The receiving member includes an upright wall formed at one end portion, and a notch portion in which both side portions of the upright wall are cut out and a swinging member (such as a ring member) is swingably mounted. It may be. For example, on both sides of the standing wall of the receiving member, a ring member as a swinging member is loosely fitted to form a slidable cutout (such as a U-shaped or U-shaped cutout). A ring member as a swing member may be attached to the attachment unit by attaching the ring member to the notch.

  The receiving member includes a standing wall formed at one end, a mounting hole formed in the standing wall, and support portions formed on both side portions on the distal end side (front side) from the mounting hole, You may provide the side wall part formed in the both sides of the front-end | tip part side from this support part, and the shaft support hole formed in this both side wall part. That is, the receiving member has a mounting hole (a mounting hole formed in the standing wall) for the pressing member in order to rotatably mount the pressing member. This mounting hole is usually formed in the lower part of the standing wall in many cases. In addition, it is advantageous to form a support portion for supporting the clamping member in order to open the tip of the clamping member in the receiving member. In many cases, the support portion is formed on both side portions on the tip end side (front side) of the mounting hole, and it is advantageous to form the support portion at the same position as the upper inner wall of the mounting hole or higher than the upper inner wall. It is. Further, in order to support or pivotally support the pressing member in the receiving member, the side wall portions formed on both side portions closer to the distal end side than the support portion, and the shaft support holes formed on the both side wall portions. And the height position of the shaft support hole may be the same as or higher than the support portion.

  The clamping member includes a fulcrum protrusion (fulcrum) that can be engaged with the mounting hole of the upright wall, a support protrusion that extends to both sides and can be supported by the support portion (extends in a wing shape on both sides, and A support protrusion that can be supported by the support portion) and a tooth-shaped pinching portion formed at the tip portion (a pinching portion at the tip portion for pinching or pinching the sheet in relation to the receiving member). The front end portion (clamping surface) of the pinching portion may be provided with a concavo-convex process or may be formed in a concavo-convex shape or a tooth shape in order to improve the retaining property with respect to the sheet.

  The clamping member is a spring deformable member (for example, a plate-like spring) in order to smoothly rotate (clamp or release) using spring elasticity and firmly clamp or clamp the sheet. Member). Using such a spring member, one end portion of the pinching member is engaged with the receiving member, and the other end portion (tip portion) is lifted and supported by the support portion of the receiving member. When a release operation (rotation operation toward one end of the pinching member) is performed, the other end (tip) of the pinching member rises elastically (spring) due to spring elasticity, and the receiving member A pair of clamping parts with a clamping member opens rapidly. When the sheet is arranged between a pair of opened clamping parts and rotated in the closing direction of the pressing member, the sheet can be clamped by the clamping part of the clamping member, and when the pressing member is laid down, the pressing member The sheet can be firmly pinched or pinched by the pinching portion of the pinching member while restricting rotation in the opening direction. Therefore, it is possible to smoothly perform the attachment or replacement work of the seat.

  The cross-sectional shape of the pinching member is not particularly limited, and may be a shape where the front region (tip end side) is curved or bent in a direction approaching the pressing member side with respect to the engaging portion with the receiving member. For example, the pinching member includes a pressed portion formed in a front area from an engaging portion with the receiving member, and is formed in a front area from the pressed portion, and is bent or bent in a direction approaching the pressing member side. An inclined wall portion formed in this manner, a pinching wall that bends or descends toward the receiving member at the tip of the inclined wall portion, and a tooth-shaped pinching portion formed on the pinching wall. Good. In many cases, the pressed portion is flat, and an extended portion extending substantially parallel to the pressed portion from the inclined wall portion may be interposed between the inclined wall portion and the pressing wall.

  Furthermore, the pressing member only needs to be rotatable with respect to the receiving member and be able to press the clamping member. For example, the pressing member may include a cam mechanism in order to press the clamping member in association with the turning operation. The pressing member includes a shaft supporting portion that can be rotatably mounted in the shaft supporting hole of the receiving member, and the pressing member (at least the pressed member to be pressed) in a closed state in accordance with a closing operation centering on the shaft supporting portion. A pressing portion (pressing wall) that can press the portion). In many cases, the pressing portion is formed by bending or curving one end portion of the pressing member, and is a pressing wall having a height suitable for pressing the pinching member. The shape of the pressing portion (pressing wall) is not limited to a curved shape in which the lower portion (side in contact with the pressing member) is curved, and may be a shape in which the lower portion is flat, a shape in which the lower portion is uneven, or the like.

  Furthermore, in the closed state (or with respect to the operation part), the pressing part (pressing wall) hangs down (for example, from the shaft support part with respect to the receiving member or from one end side (standing wall side) slightly from this shaft support part. Or may be inclined toward one end (the standing wall direction of the receiving member) or the tip (the other end). In a preferred embodiment, the pressing portion (pressing wall) is suspended or inclined toward one end portion (the standing wall direction of the receiving member). When the pressing part (pressing wall) is inclined in this manner, the strongest pressing force is applied when the tip of the pressing part (pressing wall) that rotates in the closed state is located at the lowermost part (hanging part). When passing through the lowermost part, the tip of the pressing part is positioned on the standing wall side with respect to the shaft support part, and the closing operation by the pressing member is completed elastically, and the pressing part is rotated in the opening direction. Can be regulated.

  In order to increase the clamping force (or clamping force) of the seat, the receiving member may be provided with a rubber member (or cushioning material) or an anti-slip member that can contact with the seat and be clamped by the clamping member. Good. Moreover, you may form the tooth-like part which faced the clamping member side in the front-end | tip part of a receiving member. In this aspect, a tooth-like portion may also be formed at the tip of the pinching member. In such a form, not only the front end portion of the pinching member but also the tooth-like portion of the front end portion of the receiving member can prevent the sheet from being detached. Furthermore, tooth-shaped portions may be formed at the front end portions of the pinching member and the receiving member so as to face each other.
