Description

  The present invention relates to a folding door guide that moves along a guide rail by fitting a rail-side main body elastically supported upward to the guide rail from below.

  A folding door composed of a fixed-side door plate and a movable-side door plate connected to each other flexibly is attached to the moving-side door plate, and the moving-side door plate is moved by moving the guide tool along a guide rail fixed to the upper edge of the opening. Is guided along the guide rail and opened and closed. The guide tool includes a rail-side main body that slides at least along the guide rail. In recent years, in addition to the rail side main body, a recent guide has a door side main body to be attached to the moving side door plate, and the rail side main body can be horizontally swiveled with respect to the moving side door plate of the folding door via the door side main body. Bullet upwards. Thereby, the rail side main body adjusts the degree of fitting with respect to the guide rail, absorbs the variation in the dimensions of the guide rail, and suppresses rattling of the door plate when the guide tool slides.

  As a specific folding door guide, for example, as seen in Patent Document 1, a columnar rail-side main body (runner guide) is moved upward by a spring from a door-plate side main body (runner main body) attached to the back surface of the folding door. There is a configuration in which the rail-side main body is fitted from below into a guide rail having a concave cross section. Moreover, although it is only a rail side main body, as seen in patent document 2, the guide groove (groove) provided in the rail side main body (runner) attached to the back surface of the folding door is used as the main rail (rail) of the guide rail. There is a loose fit.

  In the guide tool of Patent Document 1, it is necessary to increase the clearance of the rail-side body with respect to the groove of the guide rail in consideration of manufacturing errors between the inner dimension of the groove of the guide rail and the outer dimension of the rail-side body. . For this reason, a relatively large gap is generated between the rail-side body and the guide rail, and when the folding door is opened and closed, as well as in the state where the folding door is completely closed, when the wind blows on the fixed side door plate or the moving side door plate, There is a problem that the entire folding door rattles.

  On the other hand, since the guide rail of Patent Document 2 is affected only by the thickness error of the main rail, the clearance between the guide groove of the rail side body and the main rail of the guide rail is reduced, and the folding of the folding door Sticking can be suppressed. However, in reality, dirt or dust may adhere to the guide groove of the rail side main body and the frictional resistance may increase, so that a large clearance is assumed assuming that the dust or dust adheres. Also, since the side surface of the guide groove is in sliding contact with the main rail, the guide tool swings back and forth during the folding door opening and closing operation, and an unbalanced load is applied to the rail side body, increasing the frictional resistance of the rail side body against the main rail. There is also a problem that the opening and closing operation of the folding door is heavy. As described above, conventionally, there has been no guide tool that achieves good sliding while preventing rattling. Therefore, in order to develop a guide that does not rattle and realizes good sliding, it was studied.

  As a result of the study, we developed a guide for a folding door that moves along the guide rail by fitting a rail-side main body that is pivoted horizontally and elastically supported upward with respect to the moving side door plate of the folding door from below. The rail-side body is formed by loosely fitting a guide groove that opens upward from a main rail projecting downward from the guide rail from below, and the guide groove does not slide the side surface of the main rail. The side surfaces of the guide rail and the bottom surface of the main rail have a substantially U-shaped cross section, and the side slide contact portions protrude from the side surfaces of the guide groove, and are downward from the bottom surface of the guide groove. The sliding door is projected, and the side sliding contact portion and the downward sliding contact portion are brought into sliding contact with the main rail, respectively. The sliding contact of the side sliding contact portion with respect to the main rail may be point contact, but preferably the side sliding contact portion is brought into line contact or surface contact with the main rail.

  The side sliding contact portion that makes point contact with the main rail can be configured as a frustum-shaped or dome-shaped convex portion that makes sliding contact with the main rail at one point, and the side sliding contact portion that makes line contact with the main rail has a sliding contact edge as a vertex. The side slidable contact portion in surface contact with the main rail can be configured as a frustum-shaped convex portion having a slidable contact surface. These side sliding contact parts keep the side of the guide groove away from the main rail and reduce the frictional resistance while stably supporting the entire rail side body fitting the guide groove to the main rail with respect to the main rail, Has the function of suppressing rattling. Considering the point which suppresses the shakiness of the rail side main body with respect to a main rail especially, it is preferable that a side sliding contact part does not make a point contact to a main rail, but a line contact or a surface contact.

  When the guide groove is protruded at a position where the side sliding contact portion and the lower sliding contact portion coincide with the sliding direction of the rail side body, the rail side body is supported at three points with respect to the main rail of the guide rail. This realizes stable sliding of the rail side body. As a result, even if the guide tool swings back and forth within the vertical plane, the lower edge of the main rail does not come into contact with the side surface of the guide groove. Movement can be secured. Moreover, when considering the point of suppressing the rattling of the rail side main body with respect to the main rail, it is preferable that the guide groove is provided in parallel with a plurality of side sliding contact portions in the sliding direction of the rail side main body. It is preferable that a plurality of downward sliding contact portions are arranged side by side in the sliding direction of the rail side main body. As a result, the guide tool does not swing left and right within the horizontal plane with one side sliding contact portion as a fulcrum, and each side sliding contact portion can evenly make line contact or surface contact with the main rail. In addition, it is possible to reduce the frictional resistance due to all the side sliding contact portions.

  Further, the guide groove is provided with a vertical groove having a depth greater than that of the lower sliding contact portion on the front or rear side in the sliding direction of the rail-side body with respect to the side sliding contact portion. A solid or pasty lubricant such as grease may be retained. Thereby, the lubricant retained in the longitudinal groove is supplied between the side sliding contact portion and the main rail, and the frictional resistance due to the side sliding contact portion can be reduced. Here, the guide groove is provided with a blocking piece slidably contacting the main rail on the opposite side of the side slidable contact portion across the longitudinal groove, and the side slidable contact portion is provided with a semi-solid or pasty lubricant. And it is good to make it hold | maintain in the vertical groove between the blocking pieces. More preferably, the blocking piece includes a pair of side blocking pieces protruding from the side surfaces of the guide groove and a bottom surface of the guide groove in a positional relationship corresponding to each of the side sliding contact portion and the lower sliding contact portion. It is good to comprise from the downward blocking piece projected from.

  In addition, the guide groove includes a wiping portion that is slidably contacted with the main rail at a side surface that is front or rear in the sliding direction of the rail-side body with respect to the side sliding contact portion and at least in the same height range as the side sliding contact portion. When provided, the wiping member wipes off dust, dirt, etc. adhering to the main rail, so that dirt, dust, etc. do not enter between the side sliding contact portion and the main rail, and the guide tool slides smoothly. Can be maintained.

  The guide tool of the present invention is such that only the side sliding contact portion and the lower sliding contact portion provided on both side surfaces of the guide groove of the rail side main body are slidably contacted with the main rail of the guide rail. The frictional resistance of the rail side main body with respect to the main rail of the guide rail is reduced while the clearance of the guide rail is reduced. Thereby, the guide of this invention has the effect which can implement | achieve and maintain favorable sliding, suppressing the rattling at the time of opening and closing of a folding door.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a rear view showing a closed (extended) state of a folding door 2 to which a guide 1 of the present invention is attached. FIG. 2 shows the guide 1 and guide rail 3 in a state in which the folding door 2 is opened (folded). 3 is a side view showing the guide 1 and the guide rail 3 in a state in which the folding door 2 is closed, FIG. 4 is a plan view showing the guide 1 of this example, and FIG. 6 is a cross-sectional view taken along the line BB in FIG. 4, FIG. 7 is a cross-sectional view taken along the line CC in FIG. 4, and FIG. 8 is a cross-sectional view of the rail-side main body 11 in the guide 1 of this example. It is the partially broken perspective view cut | disconnected by C equivalent.

  As shown in FIG. 1, the folding door 2 of this example is an outer set type (covering assembly type) composed of a fixed side panel 21 and a moving side panel 22 connected in a bending relationship, and is attached to the opening 4 of the building. . The guide rail 3 is attached to the upper edge of the opening 4. The fixed door 21 is pivotally attached to the side edge of the opening 4 by two fixed upper hinges 212. Further, the movable side door plate 22 is provided with a turnable guide 1 attached to the outer upper corner on the back side, and the guide 1 is moved along the guide rail 3 as shown in FIG. , Will be guided.

  The guide rail 3 is a metal mold member composed of a main rail 31 and a drop-off preventing rail 32 extending in the longitudinal direction. The main rail 31 has a cross-sectional I (eye) shape protruding downward. Further, the drop-off prevention rail 32 has an L-shaped cross section including a vertical surface 321 hanging parallel to and away from the main rail 31 and a horizontal surface 322 folded back toward the main rail 31. The drop-off prevention rail 32 wraps the horizontal surface 322 below the drop-off prevention block 115 provided on the rail-side main body 11 of the guide 1 to prevent the guide 1 from dropping off from the guide rail 3.

  In this example, an overpass block 323 having an inclined surface protruding gradually from the vertical surface 321 is fixed to the main rail 31 side of the vertical surface 321 of the drop-off prevention rail 32 in the vicinity of the moving end of the moving side door plate 22. In the guide 1, the brake block 116 urged toward the vertical surface 321 of the drop-off prevention rail 32 by the protruding coil spring 117 is protruded from the drop-off prevention block 115. The overpass block 323 pushes the brake block 116 on the inclined surface and pushes it, and pushes the rail-side main body to the main rail 31 through the push of the brake block 116. As a result, the side sliding contact portion 123 protruding from the side surface 121 of the guide groove 12 is pressed against the main rail 31, and braking is applied to the rail side main body 11.

  In addition, the overpass block 323 of this example is provided with a stopper portion 324 as a terminal end of the moving side door plate 22. The moving side door plate 22 restricts the moving range in a state in which the folding door 2 is opened (folded) by bringing the stopper block 324 into contact with the drop-off preventing block 115 of the rail side main body 11. The stopper portion 324 is formed of a soft material such as a sponge so that the falling-off prevention block 115 of the rail side body 11 may collide due to a sudden opening and closing of the door plate. It is good to prevent the occurrence.

  As shown in FIGS. 2 to 4, the guide tool 1 of this example is configured such that the rail side main body 11 that fits the guide groove 12 from below into the main rail 31 of the guide rail 3 can be turned to the moving side door plate 22. It is a configuration in which it is elastically supported with respect to the turning arm 13 which is the door plate side main body attached to the shaft. The swivel arm 13 of this example is pivotable by pivotally attaching a swivel end 132 to a recess 221 provided on the back side of the moving side door plate 22, and the rail-side body 11 swivels integrally according to the swivel arm 13. . Here, since the rail-side main body 11 is fixed in posture with respect to the guide rail 3, the moving side door plate 22 can turn with respect to the rail-side main body 11 that moves along the guide rail 3 when turned upside down. .

  The swivel arm 13 is an L-shaped block body in plan view in which a swivel end 132 is pivotally attached to a recess 221 provided on the back side of the moving side door plate 22. The swivel arm 13 is configured by loosely fitting a lifting end 131 to two pins 113 that are vertically installed between an upper protrusion 111 and a lower protrusion 112 projecting above and below the rail-side main body 11 so as to freely move up and down. Yes. In this example, the coil support spring 114 is interposed between the lifting / lowering end 131 of the swivel arm 13 and the upper protrusion 111 of the rail-side main body 11, so that the lifting / lowering end 131 of the swiveling arm 13 is supported. The rail side main body 11 is supported elastically. The length of the pin 113 is longer than that of the swivel arm 13, and the lifting and lowering allowance of the swivel arm 13 is left above and below the swivel arm 13 with the rail-side main body 11 being resiliently supported via the spring coil 114 for support. . As a result, the rail-side body 11 moves up and down with respect to the swivel arm 13 so that the lower sliding contact portion 124 of the guide groove 12 is in sliding contact with the lower edge of the main rail 31, and the dimensions of the opening 4 and the guide rail 3 are increased. Absorbing the variation of.

  The rail-side body 11 is a resin block provided with a guide groove 12 that is loosely fitted to the main rail 31 of the guide rail 3 from below. As described above, the rail-side main body 11 of this example has two pins 113 erected vertically between the upper protrusion 111 and the lower protrusion 112 projecting up and down. By fitting, it is supported by the turning arm 13. Further, the rail-side main body 11 of this example is integrally provided with a drop-off prevention block 115 having a built-in brake block 116 that protrudes toward the drop-off prevention rail 32 of the guide rail 3. The rail-side main body 11 has a guide groove 12 formed on the upper surface by cutting. The rail side main body 11 moves along the main rail 31 by loosely fitting the guide groove 12 to the main rail 31 of the guide rail 3 from below.

  The guide groove 12 is a cut having a width wider than that of the main rail 31. In this example, the width of the guide groove 12 is about three times the thickness of the main rail 31. As shown in FIG. 7, the guide groove 12 includes a pair of side slidable contact portions 123 slidably contacting the side surface of the main rail 31 and a lower slidable contact portion 124 slidably contacting the lower edge of the main rail 31. Two sets are provided with a gap in the sliding direction of the rail-side body 11. Then, in the guide groove 12 sandwiched between each set of the side slidable contact portion 123 and the lower slidable contact portion 124, the lower slidable contact portion 124 along the set of each side slidable contact portion 123 and the lower slidable contact portion 124. A longitudinal groove 125 having a greater depth is provided, and further, a side sliding contact portion 123 and a downward sliding contact portion 124 are formed inside the guide groove 12 opposite to the side sliding contact portion 123 sandwiching each longitudinal groove 125. A side blocking piece 126 and a lower blocking piece 127 having the same shape are provided. Thus, each vertical groove 125 is sandwiched between the side sliding contact portion 123 and the lower sliding contact portion 124, the side blocking piece 126 and the lower blocking piece 127, and is filled in a solid or paste shape. A lubricant such as grease can be stably held.

  When viewed from the sliding direction of the rail-side main body 11, the side sliding contact portion 123 is wide and formed following the side surface 121 and the bottom surface 122 of the guide groove 12, and is opposed to each upper end of the substantially U-shaped rib in front view. The protruding portion and the downward sliding contact portion 124 correspond to the curved bottom end portion of the rib. The side sliding contact portion 123 in this example is a trapezoidal protrusion protruding with the same width as the rib, and is in surface contact with the side surface of the main rail 31. Similarly, when viewed from the sliding direction of the rail-side main body 11, the side blocking pieces 126 are narrow and substantially U-shaped ribs in front view formed along the side surface 121 and the bottom surface 122 of the guide groove 12. The part protruding from the upper end in an opposing relationship, the lower blocking piece 127 corresponds to the curved lowermost part of the rib, the side blocking piece 126 is the same position and the same shape as the side sliding contact part 123, Further, the lower blocking piece 127 has the same position and the same shape as the lower sliding contact portion 124.

  From now on, the side blocking pieces 126 and the lower blocking pieces 127 of this example are in sliding contact with the side surfaces and lower edges of the main rail 31 as in the case of the side sliding contact portion 123 and the lower sliding contact portion 124. It also has a function to support the guide portion. Strictly speaking, when the paired side sliding contact portion 123 and the side blocking piece 126 are always in sliding contact with the side surface of the main rail 31, the frictional resistance by the side sliding contact portion 123 and the side blocking piece 126 is obtained. Therefore, the side sliding contact portion 123 and the side blocking piece 126 in this example are opposed to each other with a slightly wider width than the thickness of the main rail 31, so that one pair of side sliding The contact portion 123 and the side blocking pieces 126 are in sliding contact with the main rail 31.

  Since the guide groove 12 of this example is sufficiently wider than the thickness of the main rail 31 as described above, the side surface 121 is not brought into sliding contact with the main rail 31. Further, since the side sliding contact portion 123 and the side blocking piece 126 are respectively provided in the upper part of the guide groove 12 following the upper surface of the rail side body 11, the side sliding contact portion 123 and the side blocking portion are provided. A gap is formed below the stopper piece 126. As a result, even when the rail-side main body 11 is inclined when the folding door 2 is opened and closed, the main rail 31 is less likely to come into contact with the side surface 121 of the guide groove 12, and the frictional resistance associated with the inclination of the rail-side main body 11 is reduced. As a result of suppressing the occurrence, the opening / closing operation of the folding door 2 is not made heavy.

  In addition, the guide groove 12 of this example is a set of the side sliding contact portion 123 and the lower sliding contact portion 124 outside the guide groove 12 that is not sandwiched between the side sliding contact portion 123 and the lower sliding contact portion 124. A wiping portion 128 extending vertically is provided, and dust or dust adhering to the main rail 31 is placed in the guide groove 12, particularly in the gap between the side sliding contact portion 123 and the lower sliding contact portion 124 and the main rail 31. To prevent intrusion. The wiping portion 128 is durable and can sufficiently wipe off dust, dust, etc., and is preferably a flexible face material or brush made of a material that can suppress sliding contact with the main rail 31. Examples include mohair, felt and soft nylon brushes.

  Finally, the procedure for attaching the folding door 2 having the guide 1 of the present example attached to the moving side door plate 22 to the opening 4 will be described. The folding door 2 is in a folded state, and the fixed side hinge 212 attached to the opening side edge of the fixed side door plate 21 is fixed to the side edge of the opening 4 using screws or the like. Here, in the rail side main body 11, the drop prevention block 115 interferes with the horizontal surface 322 of the drop prevention rail 32 of the guide rail 3, so that the guide groove 12 is loosely fitted to the main rail 31 of the guide rail 3 as it is. I can't. For this reason, in this example, the insertion cutout 325 is formed in a part of the horizontal surface 322 of the drop-off prevention rail 32 of the guide rail 3. The rail-side main body 11 is loosely fitted into the main rail 31 from below with the guide groove 12 of the rail-side main body 11 in a state in which the folding door 2 is folded and the dropout prevention block 115 is aligned with the insertion notch 325 (see FIG. 2 and FIG. 6). After that, when the moving side door plate 22 is moved in the closing direction, the falling prevention block 115 of the rail side body 11 is inserted into the falling prevention rail, and the attachment of the folding door 2 is completed.
