These holding recesses 97 are provided at the center of the upper surface of the main body 92 in the width direction, and have a width dimension in which the support roller 74 of the lower traveling body 61 is slidably fitted. In other words, these holding recesses 97 have an inner width dimension slightly larger than the outer diameter dimension of the support roller 74.

  Here, the height dimension from the bottom of these holding recesses 97 to the lower surface of the main body 92 is such that the running projections 93 are fitted into the running recesses 94 of the lower guide rail 4. When the lower traveling body 61 engaged is moved and the lower traveling body 61 is fitted and held in the holding recess 97, the pair of door bodies 6 to which the lower traveling body 61 is attached are horizontally disposed. The height dimension is such that the base cup 13 of the pair of door bodies 6 can be connected to the upper traveling body 12 of the upper guide rail 3 by moving.

  Each inclined surface portion 96 of the main body 92 is provided with an inclined concave portion 98 having a concave cross section that is continuous with the holding concave portion 97. These inclined recesses 98 have a longitudinal direction along the inclination direction of each inclined surface portion 96. Further, these inclined concave portions 98 are provided in the central portion in the width direction of the inclined surface portion 96 and have an inner width dimension equal to the inner width dimension of the holding concave portion 97. That is, these inclined concave portions 98 function as guides that allow the support roller 74 engaged with the traveling concave portion 94 of the lower guide rail 4 to travel over the holding concave portion 97.

  Therefore, as shown in FIG. 8, the lower traveling body 61 is horizontally placed in a state where the fitting convex portion 93 of the height holding mechanism 91 is fitted to the center portion in the longitudinal direction of the traveling concave portion 94 of the lower guide rail 4.

  At this time, the inclined recess 98 of the height holding mechanism 91 converts the movement of the pair of door bodies 6 in the horizontal direction into the movement of the pair of door bodies 6 in the height direction.

  Further, the pair of door bodies 6 are opened, and the support roller 74 of each lower traveling body 61 is moved from the holding recessed portion 97 of the height retaining mechanism 91 to the traveling recessed portion 94 of the lower guide rail 4 via the inclined recessed portion 98. After that, the height holding mechanism 91 is removed from the traveling recess 94. As a result, as shown in FIG. 10, since the pair of door bodies 6 are supported by being suspended from the upper traveling body 12, the same operational effects as those of the first embodiment can be obtained.

  Further, when the pair of door bodies 6 are moved and folded in the horizontal direction, the lower traveling bodies 61 of the pair of door bodies 6 move so as to get over the inclined recess 98 of the height holding mechanism 91. For this reason, the inclined recess 98 of the height holding mechanism 91 can convert the movement of the pair of door bodies 6 in the horizontal direction into the movement of the pair of door bodies 6 in the height direction, that is, ascending movement. Therefore, since the pair of door bodies 6 can be raised to a predetermined height and held without supporting the load of the pair of door bodies 6, the workability of the pair of door bodies 6 can be further improved. The door body 6 can be hung on the upper traveling body 12 alone.

  Next, a fourth embodiment of the present invention will be described with reference to FIGS.

  The folding door device 2 shown in FIGS. 11 to 17 is basically the same as the folding door device 2 shown in FIGS. 7 to 10, but the pair of door bodies 6 is moved in the horizontal direction. A movement conversion mechanism 101 serving as a movement conversion means for converting the movement into a height direction of 6 is provided between the upper traveling body 12 and the base cup 13 and incorporated therein.

Further, the inclined surface 104 is provided from the base end edge of the tapered surface 27 of the engagement groove 26 to the opening edge of the engagement recess 102.

  A retaining member 105 is attached to the bottom surface of the insertion recess 28 to prevent the retaining protrusion 18 of the upper traveling body 12 with the connecting shaft portion 17 locked to the engaging recess 102 from slipping out. The retaining member 105 has a flat elongated rectangular upper surface portion 106. The upper surface portion 106 has a width dimension slightly smaller than the inner width dimension of the insertion recess 28.

  The retaining member 105 is provided with a shaft insertion hole 107 penetrating in the width direction of the retaining member 105. The shaft insertion hole 107 is provided at a position spaced apart from the intermediate portion in the longitudinal direction of the upper surface portion 106 by a predetermined distance from the front end side which is one end side in the longitudinal direction of the upper surface portion 106, that is, at a shifted position. . Further, a pin body (not shown) is inserted into the shaft insertion hole 107 so as to be rotatable with both end portions protruding. Both end portions of the pin body are fixed to both side surfaces of the insertion recess 28. Therefore, this pin body attaches the retaining member 105 in the insertion recess 28 so as to be rotatable.

  In addition, spring bodies 108 as elastic members for horizontally positioning the upper surface portion 106 of the retaining member 105 are attached to both ends of the pin body. The spring body 108 urges the front side of the retaining member 105 upward by the elastic force of the spring body 108 so that the upper surface portion 106 of the retaining member 105 is held horizontal.

  Further, on the lower surface of the retaining member 105 facing the upper surface portion 106, there are a flat rectangular front inclined surface 111 and a rear inclined surface 112 which are inclined upward toward both ends in the longitudinal direction of the upper surface portion 106. Each is provided. Here, the front inclined surface 111 is provided on the front side of the retaining member 105 with respect to the shaft insertion hole 107. The rear inclined surface 112 is provided on the rear side of the retaining member 105 with respect to the shaft insertion hole 107. Therefore, the retaining member 105 is configured such that the center of gravity is positioned in front of the shaft insertion hole 107.

  On the other hand, the side surface of the upper traveling body 12 on the side connected to the connecting shaft 17 in the retaining projection 18 is slid radially from the connecting shaft 17 toward the end surface of the retaining projection 18. An inclined sliding surface 113 is provided as a moving part. The inclined sliding surface 113 forms a movement conversion mechanism 101 with the inclined surface 104 of the base cup 13.

  Therefore, as shown in FIG. 12 and FIG. 13, the pair of door bodies 6 are horizontally moved and folded, and the pair of upper traveling bodies 12 are sandwiched between the pair of door bodies 6. Thereafter, the pair of door bodies 6 are further moved horizontally and folded to engage the connecting shaft portions 17 of the upper traveling bodies 12 with the engaging groove portions 26 of the base cup 13, and the upper traveling bodies 12. The inclined sliding surface 113 of the retaining protrusion 18 is brought into contact with and engaged with the inclined surface 104 of the base cup 13.

  In this state, the pair of door bodies 6 are further moved horizontally and folded, and as shown in FIGS. 14 and 15, the inclined sliding surface 113 of the retaining protrusion 18 of each upper traveling body 12 is attached to the base cup 13. It is made to slide with respect to the inclined surface 104. At this time, the sliding of the inclined surface 104 of the base cup 13 by the inclined sliding surface 113 of the retaining protrusion 18 of each upper traveling body 12 causes the pair of door bodies 6 to move in the horizontal direction. It is converted into a movement of the body 6 in the height direction.

  Thereafter, the pair of door bodies 6 are further moved in the horizontal direction, and the connecting shaft portion 17 of each upper traveling body 12 is pressed against the engaging recess 102 of the base cup 13 to elastically deform the engaging recess 102. And is engaged with the engaging recess 102 in a rotatable manner. At this time, the front side of the top surface portion 106 of the retaining member 105 is pressed by the bottom surface portion of the retaining projection 18 of the upper traveling body 12, and the retaining member 105 rotates toward the front side.

  Further, the retaining protrusions 18 of the upper traveling bodies 12 are engaged with the engaging recesses 102 of the base cup 13 by the connecting shaft portions 17 of the upper traveling bodies 12, and the insertion recesses 28 of the base cup 13 are inserted.

At this time, the pressing of the upper surface portion 106 of the retaining member 105 by the retaining projection 18 is released by the engagement of the base cup 13 with the engaging recess 102 by the connecting shaft portion 17 of each upper traveling body 12.

  When the pressing of the upper surface portion 106 of the retaining member 105 by the retaining protrusion 18 is released, the retaining member 105 is rotated toward the rear side by the elastic force of the spring body 108. Thus, the locking in the insertion recess 28 of the base cup 13 by the locking protrusion 18 of the upper traveling body 12 is held at the front end portion of the locking member 105 so as not to come off. As a result, as shown in FIGS. 16 and 17, since the pair of door bodies 6 are supported by being suspended from the upper traveling body 12, the same operational effects as those of the third embodiment can be obtained.

  Furthermore, with the inclined surface 104 of the base cup 13 in contact with the inclined sliding surface 113 of the upper traveling body 12, the pair of door bodies 6 are moved in the horizontal direction and folded to thereby tilt the base cup 13. The inclined sliding surface 113 of the upper traveling body 12 slides on the surface 104, and the movement of the pair of door bodies 6 in the horizontal direction is converted into the movement of the pair of door bodies 6 in the height direction. .

  As a result, the pair of door bodies 6 can be moved upward by the retaining member 105 in the base cup 13 of the pair of door bodies 6 only by moving the pair of door bodies 6 in the horizontal direction without supporting the load of the pair of door bodies 6. The retaining protrusion 18 of the body 12 can be pivotably retained, and the pair of door bodies 6 can be supported by being suspended from the upper traveling body 12. Therefore, the upper traveling body 12 can be more easily engaged with these base cups 13 and the installation worker can suspend the pair of door bodies 6 from the upper traveling body 12 and install the folding door device 2. Can be improved.

  Further, the movement conversion mechanism 101 is provided between the base cup 13 and the upper traveling body 12, and the movement conversion mechanism 101 is built in the base cup 13 and the upper traveling body 12. For this reason, since it is not necessary to attach or detach the movement conversion mechanism 101, it is possible to reliably prevent the movement conversion mechanism 101 from being lost. Furthermore, since the movement conversion mechanism 101 is composed of the inclined surface 104 of the base cup 13 and the inclined sliding surface 113 of the upper traveling body 12, the configuration of the movement conversion mechanism 101 can be simplified. Cost can be reduced.

  Thereafter, the upper sides of the pair of door bodies 6 are further tilted toward the front side of the opening 1, and as shown in FIGS. 21 and 22, the inclined sliding surfaces 113 of the retaining protrusions 18 of the upper traveling bodies 12. Is slid with respect to the inclined surface 104 of the base cup 13. At this time, the sliding of the inclined surface 104 of the base cup 13 by the inclined sliding surface 113 of the retaining protrusion 18 of each upper traveling body 12 causes the pair of door bodies 6 to move in the horizontal direction. It is converted into a movement of the body 6 in the height direction.

  Thereafter, the upper side of the pair of door bodies 6 is further tilted toward the front side of the opening 1, and the connecting shaft portion 17 of each upper traveling body 12 is rotatably locked to the engaging recess 102 of the base cup 13. . At this time, the front side of the top surface portion 106 of the retaining member 105 is pressed by the bottom surface portion of the retaining projection 18 of the upper traveling body 12, and the retaining member 105 rotates toward the front side.

  Further, the retaining protrusions 18 of the upper traveling bodies 12 are engaged with the engaging recesses 102 of the base cup 13 by the connecting shaft portions 17 of the upper traveling bodies 12, and the insertion recesses 28 of the base cup 13 are inserted.

  When the pressing of the upper surface portion 106 of the retaining member 105 by the retaining protrusion 18 is released, the retaining member 105 is rotated toward the rear side by the elastic force of the spring body 108. Thus, the locking in the insertion recess 28 of the base cup 13 by the locking protrusion 18 of the upper traveling body 12 is held at the front end portion of the locking member 105 so as not to come off. As a result, as shown in FIGS. 23 and 24, these pair of door bodies 6 are suspended and supported by the upper traveling body 12, so that the same operational effects as those of the fourth embodiment can be obtained.

  Further, after the retaining protrusions 18 of the upper traveling bodies 12 are engaged with the first connecting recesses 121 of the base cup 13, a second bent portion provided at a right angle with respect to the first connecting recesses 121 is provided.

Accordingly, the pair of door bodies 6 are moved in the horizontal direction by causing the inclined sliding surfaces 113 of the retaining protrusions 18 of the upper traveling bodies 12 to slide in contact with the inclined surfaces 104 of the base cup 13. Since the operation | work to convert into the movement to the height direction of the door body 6 can be made easier, the construction property of the folding door apparatus 2 can be improved more.

  Furthermore, since the second connecting recess 122 is provided along the width direction of the base cup 13, the inclination of the inclined surface 104 in the second connecting recess 122 is increased by increasing the size of the base cup 13 in the width direction. The angle can be made gentler. Therefore, by making the inclination angle of the inclined surface 104 gentle, the force required for folding the pair of door bodies 6 and moving the pair of door bodies 6 upward can be reduced. Therefore, since the pair of door bodies 6 can be suspended and supported on the upper guide rail 3 with a smaller force, the installation workability of the folding door device 2 can be further improved.
