  In this example, the upper and lower lock bars 21 and 22 are each provided with a roller 23 (the upper end is not shown) at the upper end of the upper lock bar 21 and the lower end of the lower lock bar 22 using, for example, stainless steel pipes. The roller 23 is engaged with and disengaged from the guide rails 6 and 7, that is, the grooves of the groove rails, so that the hinge frame 10 can be prevented from swinging when locked by engagement with the guide rails 6 and 7. It is.

  In this example, the back plate 24 is a plate-like member with a shaft support piece including a back plate substrate and an integral shaft support piece 25 standing upright on the back plate substrate, and the back plate substrate is hinged. For example, a fixing bracket 38 such as a screw or a rivet is fixed to the rear surface of the frame 10, and the shaft support piece 25 protrudes from the surface of the hinge frame 10 through a through hole formed in the hinge frame 10. In this case, the back plate 24 of this example is arranged on a slide member 28 which is installed on a lock bar 21 which will be described later and fixed to the slide case 26 together with the lock bar 21. By providing a receiving hole for receiving the urging ball 30, the back plate is also used as a stopper member for determining the slide upper limit position of the slide member 28, that is, the slide case 26.

  In this example, the slide case 26 is long in the up and down direction with a step set low on one side and high on the other side, and a guide protrusion is provided projecting toward the back surface in the low part set low. Further, a hollow portion is formed and arranged at the high part set as a high part, for example, as a member of metal casting or resin molding, and the guide protrusion is inserted into a guide groove having a predetermined length that is provided in the vertical direction of the hinge frame 10. The slide case 26 is inserted so as to slide in the vertical direction, while the hollow portion accommodates the projecting portions of the shaft support member 33 and the rotation plate 36 from the hinge frame 10. At this time, the guide protrusion of this example is provided with a through-hole penetrating the front and back for connecting the lock bar 21 described later. Further, at this time, the slide case 26 is formed on the surface of the low part for the slide operation so as to have the same area as the low part in the present example so that its height matches the height of the high part. For example, a resin-molded knob member 27 is disposed and the same knob member 27 is disposed on the hinge frame 10 with the hinge frame 10 interposed therebetween, so that the sliding operation can be performed on the indoor side and the outdoor side of the hinge frame 10. The knob member 27 is installed. In this example, the knob member 27 is arranged in such a manner that a bolt 31 is inserted into a through hole formed in the guide projection of the slide case 26, a nut 32 is screwed to the tip, and is fixed integrally with the bolt and nut. On the case 26 side, a fixing bracket 38 such as a screw is screwed into the knob member 27 from the lower surface of the lower portion to fix the case.

  In the locking device A of the present example, the slide case 26 is arranged at an operation position in the longitudinal direction on the indoor side surface of the hinge frame 10 so that the lower part is positioned higher and the higher part is positioned lower. The member 27 is installed on the indoor side and the outdoor side of the hinge frame 10, and the sliding operation is performed by the guide groove of the guide protrusion. In this example, the longitudinal end, that is, the lower end of the upper lock bar 21 is connected, and the upper lock bar 21 is directly moved up and down in the hinge frame 10 by the sliding operation. At this time, the upper lock bar 21 is connected to the slide case 26 by arranging a slide member 28 slidable in the hinge frame 10 at the end of the lock bar 21 connecting side to prevent the lock bar 21 from swinging. As done in the state.

  In this example, the slide member 28 includes a fitting insertion portion that is fitted into the hollow portion of the hinge frame 10, a lock bar receiving hole formed in the fitting insertion portion, and a fitting that is installed at the tip of the lock bar receiving hole. The upper lock bar 21 is inserted into the lock bar receiving hole and the fitting protrusion is fitted to the tip of the lock bar, for example, from the wall surface of the lock bar receiving hole. The slide member 28 is fixed to the lock bar 21 by a fixing bracket 38 such as a screw or a rivet, and the bolt 31 from the lower part of the slide case 26 is connected to the slide member 28 while the slide member 28 is fixed. The lock bar 21 is connected to the slide case 26 by penetrating through the lock bar 21, for example, through the through hole at the position of the fitting protrusion.

  At this time, the slide member 28 further extends the lower end thereof downward, and the side surface on the inner side of the one side corresponds to the thickness of the back plate so as to be a clearance space for the back plate 24 disposed on the hinge frame 10. A single step or a plurality of urging balls 30 urged toward the front side by a spring 29 on the back surface, which is disposed in the step portion and is fitted in the receiving hole provided in the back plate. The slidable member 28, that is, the slide upper limit position of the slide case 26 can be regulated by freely installing the urging ball 30 by rolling the back plate 24 to reach the receiving hole and fitting into the receiving hole. It is like that.

The shaft support member 33 accommodated in the high part of the slide case has a pair of wall surface portions, a connecting portion connecting the wall surface portion to one end side of the wall surface portion, and opening the other end side of the wall surface portion. And a metal plate working or metal casting or resin-molded cross-sectional U-shape, and the pair of wall surfaces have a through hole for pivot support of the rotation plate, and one end of the rotation plate 36 at the connecting portion. The shaft support member 33 is inserted into the hollow portion with the connecting portion directed in the depth direction of the hollow portion of the slide case 26, and from the outside of the high portion of the slide case 26. The connecting portion is fixed by fixing brackets 38 such as screws and rivets.

  The rotation plate 36 has shaft support holes at both ends and an intermediate part in the longitudinal direction, and in this example, a center part, and a shaft support hole arranged at one end in the longitudinal direction is a long hole in the longitudinal direction, and the remainder is circular. The rotation plate 36 is provided with a shaft support member 33 accommodated in the slide case 26 with a shaft support hole having a long hole. , The shaft support hole formed as an intermediate circular hole is rotated to the shaft support piece 25 of the back plate 24, and the shaft support hole formed as the other circular hole is rotated to the upper end of the lower lock bar 22 in this example. It is pivotally supported. The pivot plate 36 is pivotally supported on a pivot support member 33. The pivot plate 36 is inserted between a pair of wall surfaces, and screws, pins, rivets, etc. disposed between the pair of wall surfaces. By passing the support shaft 34 through the long shaft support hole of the rotation plate 36, the displacement width toward the slide case 26 due to the locus of the rotation radius accompanying the rotation of the rotation plate 36 is absorbed and rotated. The projecting width of the moving plate 36 is made as small as possible so that it can be rotated, and is located on the shaft support piece 25 of the back plate 24. The bracket 38 can be rotated, and the lower lock bar 22 is superposed on the shaft support plate 37 projecting from the upper end thereof, and can be rotated by the fixed bracket. .

  At this time, the shaft support plate 37 protruding from the lower lock bar 22 is a metal plate processed with a shaft support hole at one end and a fixing hole at the other end. Insert the lock bar 22 into the hollow portion from the upper end, screw the screw into the fixing hole from the outside of the lock bar 22, and fix the shaft support hole so that it protrudes from the upper end of the lock bar 22. is there.

  In the lock device 20 configured as described above, when the knob member 27 is held and slid upward, the upper lock bar 21 rises via the slide case 26 while the slide case 26 As the shaft support member 33 is lifted, the pivot plate 36 pivotally supported in the middle in the longitudinal direction on the shaft support piece 25 positioned at a fixed position by the back plate 24 fixed to the hinge frame 10 is provided. Rotating about the pivot portion of the piece 25, pivoting the pivot plate 36 at the other end and lowering the lower lock bar 22 in conjunction with it, raising the upper lock bar 21 and lower lock As a result of the interlocking descent of the bar 22, the tip ends engage with the guide grooves of the upper guide rail 6 and the lower guide rail 7, and the hinge frame 10 is held by the guide rails 6 and 7, so that the folding door 5 is locked. On the contrary, when the knob member 27 is slid downward, the upper lock bar 21 is lowered, and the rotation plate 36 performs the reverse operation, so that the lower lock bar 22 is raised in conjunction. The tips of the folding doors 5 are released from the guide grooves and the hinge frame 10 is freed, and the folding door 5 is unlocked. At this time, in this example, the upper lock bar 21 is connected to the slide case 26 via the slide member 28, so that the slide member 28 prevents the upper lock bar 21 from swinging in the hinge frame 10. The urging ball 30 installed on the slide member 28 rolls the back plate 24 and fits into the receiving hole so that the frictional resistance can be reduced when the knob member 27 is operated. Thus, the sliding operation can be performed smoothly by reducing the weight, and the upper limit position of the slide is regulated by the engagement of the urging ball 30 so that the guide projection of the slide case 26 becomes the hinge frame 10. It is also possible to eliminate noise caused by abutting against the end portion of the guide groove. Further, since the shaft support hole on the shaft support member 33 side of the rotation plate 36 is a long hole, the rotation plate 36 in the shaft support member 33 can be rotated even if the shaft support position of the shaft support member 33 is set to a fixed position. It can be performed as smoothly and compact as possible, and since the end of the rotating plate 36 in the longitudinal direction is an arc edge and the escape hole 35 is provided in the shaft support member, it is necessary to rotate the rotating plate 36. The space can be reduced as much as possible, and the protruding width of the slide case 26 from the hinge frame 10 can be suppressed as much as possible.

  Reference numeral 39 in the figure indicates that the upper lock bar 21 can be prevented from swinging by installing the slide member 28 on the upper lock bar 21 in this example. Since no sliding member is used, the lower end of the hinge frame 10 is screwed to the lower end of the hinge frame 10 so as to prevent its swinging, and the lower lock bar 22 is inserted through the through hole to guide its ascent Reference numeral 40 denotes a washer, reference numeral 41 denotes a fixing screw for the anti-vibration plate 39, and reference numeral 42 denotes an attachment shaft to the lower lock bar 22 of the roller 23 installed at the lower end of the hinge frame 10.

  Although the illustrated example is as described above, the above slide case is vertically inverted and connected to the upper end of the lower lock bar, and the pivot plate is pivotally supported on the lower end of the upper lock bar. The slide operation of the slide case can be reversed and the lock device can be locked and released. The slide case is installed on the indoor side of the hinge frame, and the lock and its lock can be Folding door, its door, hinge frame, lock device, its lock bar, back plate, slide case, rotating plate, necessary for implementing the present invention, including enabling release, etc. The specific shapes, structures, materials, relationships, additions to these, etc., such as knobs and slides used depending on Rukoto can.
