It is also possible to form a round hole having a size corresponding to the adjustment allowance of the mounting bracket 62 by interposing a washer.

  As shown in FIGS. 16 to 18, the moving side end frame 17 includes a U-shaped connecting portion 17 a having a pair of front and rear vertical bars 19 formed on the open side, and a rectangular tube protruding from the central portion of the connecting portion 17 a. And an abutting frame portion 17b. The contact frame portion 17b of the moving side end frame 17 is provided with opening / closing handles 24 on both front and rear sides thereof, locking means provided on the end surface side opposite to the suspension side, and an operating rod on the upper side of the rear side handle 24. 27, a drop bar 26 is provided on the lower side by external attachment or the like.

  As shown in FIGS. 16 to 18, the operating rod 27 is held by a grooved holding member 72 so as to be slidable up and down. The holding member 72 has a vertically long groove portion 72a that is open on the rear side, and is disposed in the vertical direction from the vicinity of the upper side of the handle 24 to the upper end of the moving side end frame 17, and is fixed by fixing tools 73a and 73b such as screws in the groove portion 72a. It is fixed to the moving side end frame 17.

  The operating rod 27 is held on the rear end open side of the groove 72a of the holding member 72, and can be slid up and down between a lowered position and a raised position that pushes the hanging tool 38 into a detached state. Under the operating rod 27, an operating portion for operating the operating rod 27 in the upward direction, such as a handle 27a, and a spring 74 such as a tension spring for biasing the operating rod 27 downward to the lowered position are provided in the front and rear. It has been. The handle 27a protrudes rearward from the groove 72a of the holding member 72, and is fixed to the operation rod 27 via an attachment member 27b. The attachment member 27b has a vertically long shape substantially the same width as the holding member 72, and is in close proximity to or in contact with the rear end surface of the holding member 72 so as to be movable up and down relatively.

  The spring 74 is disposed vertically in the groove 72a of the holding member 72 on the front side of the operation rod 27, and the upper end is attached to the operation rod 27 by a spring hook 74a such as a screw, and the lower end is attached to the fixing tool 73a. The operating rod 27 passes through the opening 41a on the lower surface side of the support base 37 when the operating rod 27 is lifted, and the hanging tool 38 is lifted. ing. Further, the operating rod 27 has its spring hanger 74a and its head abutting against the head of the fixture 73b so as to restrict the upper limit.

  In the suspension type extendable door having such a configuration, if the handle of the moving side end frame 17 of each extendable door body 4 is gripped and operated in the left-right direction, a plurality of door wheels 5, 5a are formed along the guide rail 3. It travels and the telescopic door body 4 in a suspended state extends and contracts in the left-right direction via the door wheels 5 and 5a. For this reason, an entrance / exit etc. can be opened and closed easily.

  When closing the doorway or the like, the moving side end frames 17 of the telescopic door bodies 4 are brought into contact with each other, and then both the moving side end frames 17 are locked by the locking means. Further, if necessary, the drop bars 22 and 26 are dropped into the drop holes 21 and 25 on the ground g side to lock the telescopic door bodies 4. When opening the doorway or the like, each telescopic door body 4 is moved toward the suspension column 1 as shown by the alternate long and short dash line in FIG. 2 and contracted, or as shown by the dotted line in FIG. The telescopic door body 4 is rotated around the longitudinal axis 8c of the hinge means 8 to the rotary storage position B and stored rearward.

  Normally, the rotating rail 7 is at a connection position A where it is connected to the fixed rail 6 as shown in FIG. 4, and is locked by the rail locking means 10 at the connection position A. That is, the hook 38 of the rail lock means 10 is engaged with the receiving member 35 from the upper side, and the rotating rail 7 is fixed so as not to rotate around the vertical axis 8c. Therefore, each door wheel 5, 5 a can freely travel between the fixed rail 6 and the rotating rail 7, and does not interfere with the opening / closing of the telescopic door body 4.

  Since the free end side of the rotating rail 7 rides on the rail support 9, the rotating rail 7 is cantilevered with respect to the suspension side end frame 16. It is possible to prevent sagging. When the rotary rail 7 is at the connection position A, the pressed member 49 of the door lock operating means 13 is in contact with the pressing member 50 as shown in FIG. It is pushed to the rear side and is in the release position. Therefore, the door carts 5 and 5 a can travel on the rotating rail 7 regardless of the door lock means 12.

  When the telescopic door body 4 is rotated and accommodated, first, the telescopic door body 4 is contracted to the minimum state on the suspension column 1 side as shown by the one-dot chain line in FIG. 2 and FIGS. Then, all the three door wheels 5 and 5a of the telescopic door body 4 move to the rotating rail 7 side, and the telescopic door body 4 is suspended from the rotating rail 7 via the door wheels 5 and 5a. In this case, the door 5 on the suspension side sequentially travels to the rotating rail 7 and passes below the movement restricting means 11, but each other door 5 other than the door 5 a on the moving end interferes with the restricting portion 53. Never do.

  When the door 5a on the moving end passes the movement restricting means 11 to the suspension side, as shown in FIG. 11, the restricting portion 53 is opposite to the restricted portion 54 on the moving end side (fixed rail 6). Engagement) from the side) to restrict the movement of the telescopic door body 4 in the contracted state to the fixed rail 6 side. That is, when the door 5a on the moving end side passes the movement restricting means 11 to the suspension side, the restricted portion 54 comes into contact with the restricting portion 53 of the elastic restricting member 55 and the elastic deforming portion 57 is deformed so that the upper portion is moved upward. Elastically deformed. Then, after the regulated portion 54 passes, the regulating portion 53 is restored and lowered to engage the regulated portion 54 from the anti-suspending source side (fixed rail 6 side), and fix the contracted telescopic door body 4. The movement to the rail 6 side is restricted. For this reason, after the telescopic door body 4 contracts, the door pulley 5a does not inadvertently move to the fixed rail 6 side and drop off from the rotating rail 7.

  Next, the handle 27a of the operating rod 27 of the moving side end frame 17 is gripped and operated upward against the spring 74, and the operating rod 27 is moved from the lowered position (solid line position in FIG. 16) to the raised position (two in FIG. 16). (Dash-dot line position) Then, the operating rod 27 comes into contact with and pushes up the hanging tool 38 from the opening 41a of the support base 37, and the hanging tool 38 is counterclockwise around the support shaft 42 against the spring 43 as shown by a two-dot chain line in FIG. Rotate and disengage from the receptacle 35.

  In this state, when the handle 27a of the operation rod 27 is gripped and pulled backward, the telescopic door body 4 rotates around the hinge means 8 from the connection position A to the rotation storage position B side, and the hook 38 is a receiving member. 35 is disengaged toward the engagement guide 40 side. As a result, the lock of the rotating rail 7 with respect to the fixed rail 6 can be released.

  At the connection position A, the distal end side of the rotating rail 7 is placed on the rail holder 9, but the state of the operating rod 27 passes through the opening 41a of the hanging tool 38, so that the handle 27a is gripped and pulled backward. Sometimes, a rear rotational force is applied to the free end side of the rotating rail 7 through the operation rod 27, and the rotating rail 7 is easily detached from the rail holder 9 while rotating integrally with the telescopic door body 4. Can do.

  Thereafter, the handle 27a of the operation rod 27 is changed from the handle 27a to the handle 24, and the telescopic door body 4 is rotated to the rotary storage position B as shown in FIG. When the handle 27 a of the operation rod 27 is released, the operation rod 27 is lowered to the lowered position by the spring 74, and the hook 38 of the rail lock means 10 is rotated downward by the spring 43 and lowered on the support base 37. It becomes almost horizontal. Therefore, even when the telescopic door body 4 is rotated, the hanging tool 38 is not rattled by impact, vibration or the like.

  When the rotating rail 7 and the telescopic door body 4 start to rotate around the hinge means 8 to the rotational storage position B, the door lock locking means 13 locks the door lock means 12 along with the rotation. That is, when the rotating rail 7 rotates backward in the direction indicated by the arrow a as shown in FIG. 19, the pressed member 49 of the door lock operating means 13 moves away from the pressing member 50 backward.

  For this reason, the lock pin 46 of the door lock means 12 is pushed by the spring 47 as shown by a two-dot chain line in FIG. 6 and moves in the direction indicated by the arrow c toward the anti-hanging source side of the wheel 31 on the moving end side door wheel 5a. It protrudes and engages with the door 5a on the moving end, and the door 5a on the moving end can be locked to the rotating rail 7 by the door lock means 12 so as to be substantially immovable. Therefore, when the rotary rail 7 is on the rear side from the connection position A, there is no fear that the door 5a is detached from the rotary rail 7, and the safety when the telescopic door body 4 is rotated is remarkably improved.

  Thereafter, the retractable telescopic door body 4 is suspended from the rotating rail 7, and the telescopic door body 4 is integrated with the rotating rail 7 and the suspension end frame 16 to the rotational storage position B around the hinge means 8. a Rotate in the direction of the arrow. And if it rotates to the rotation storage position B, the telescopic door body 4 will be locked with the drop stick 26 as needed.

  When the telescopic door body 4 is returned from the rotary storage position B, it is rotated around the hinge means 8 in the direction indicated by the arrow a. When the rotating rail 7 approaches the connection position A, the guided portion 44 of the hanging tool 38 is guided in the direction indicated by the arrow b by the engagement guiding portion 40 of the receiving device 35 as shown by a two-dot chain line in FIG. Then, the hanging tool 38 moves up around the support shaft 42 against the spring 43. When the rotating rail 7 rotates to the connection position A, the hook 38 gets over the engaging guide portion 40 and engages with the engaging recess 39 as shown by the solid line in FIG. To lock it immovable. Therefore, the rotary rail 7 can be automatically locked by the rail lock means 10 only by returning the rotary rail 7 and the telescopic door body 4 to the connection position A.

  Further, when the rotating rail 7 reaches the vicinity of the front side of the connection position A, the free end side rides on the rail support 9 as shown in FIG. For this reason, at the connection position A, the rotating rail 7 can be supported by the suspension-side end frame 16 and the rail support 9 in a doubly supported manner. Therefore, the rotating rail 7 can be stably supported while being connected to the fixed rail 6 in spite of being able to rotate about the longitudinal axis 8c of the hinge means 8 integrally with the suspension side end frame 16, and the telescopic door body. It is possible to prevent drooping on the free end side due to the weight of 4 or the like.

  When the rotating rail 7 further approaches the connection position A, the pressed member 49 of the door lock operating means 13 comes into contact with the pressing member 50 on the upper frame 2 side, and the pressed member 49 resists the spring 47 by the pressing member 50. Then, it is pressed backward in the direction indicated by the arrow c, and the lock pin 46 of the door lock means 12 moves to the solid line position with the rotation of the rotary rail 7 and is detached from the anti-suspending side of the door wheel 5a. For this reason, only by returning the rotation rail 7 to the connection position A, the door lock device 12 can be released by the door lock device 13 and the door lock device 12 is released. Accordingly, each door wheel 5, 5 a can be driven along the rotating rail 7, and the telescopic door body 4 can be freely expanded and contracted along the guide rail 3.

  When adjusting the mounting angle of the rotating rail 7 with respect to the suspension side end frame 16 at the time of construction or the like, the adjusting rail 66a of the angle adjusting means 66 is operated to advance and retract to adjust the rotating rail 7 upward. After that, the vertical arm portion 65 of each mounting bracket 62 is fastened and fixed to the suspension side end frame 16 by the fastening means 67. Therefore, even when the rotating rail 7 is located at a position other than the connection position A and supports the telescopic door body 4 by itself, the rotating rail 7 does not hang down below the horizontal state due to the weight of the telescopic door body 4 side. Can be maintained.

  When adjusting the mounting angle by the angle adjusting means 66, first, the fastening screws 70 of the fastening means 67 on both the front and rear sides are loosened, and in this state, the adjusting screw 66a of the angle adjusting means 66 is rotated with a tool such as a screwdriver. Then, since the tip of the adjustment screw 66a is in contact with the end frame reinforcing plate 60 on the suspension end frame 16 side, for example, as shown by a two-dot chain line in FIG. 14, each connection shaft 63 at the upper corner is used as a fulcrum. The attachment angle of the attachment bracket 62 changes, and the attachment angle of the rotating rail 7 with respect to the suspension side end frame 16 can be adjusted.

  In this case, in consideration of the weight of the telescopic door body 4 and the rigidity of the rotating rail 7, the rotating rail 7 is detached from the rail support 9 and the weight on the telescopic door body 4 in the contracted state is supported by the rotating rail 7. Then, the angle is adjusted so that the rotating rail 7 is in a substantially horizontal state. After that, the fastening screws 70 on both the front and rear sides are fastened and fixed. Also, there are mounting brackets 62 on the front and rear of the rotating rail 7, and the angle adjusting means 66 are provided corresponding to each of them, so that the angle can be adjusted separately on the front and rear of the rotating rail 7, and the angle can be adjusted separately on the front and rear. it can.

  When it is necessary to release the door lock means 12 with the rotating rail 7 rotated backward from the connection position A at the time of inspection after construction, etc., the operator pulls the lock pin 46 with the operation knob 48. Then, the lock pin 46 moves backward against the spring 47, and the lock of the door 5a on the moving end side by the lock pin 46 can be released. Therefore, although the door lock device 12 is covered with the protective cover 14, inspection and other operations can be facilitated.

  The suspension-type telescopic door having such a configuration has the following advantages. That is, the rail locking means 10 for locking the rotating rail 7 at the connection position A where the rotating rail 7 is connected to the fixed rail 6 of the guide rail 3 includes a receiving member 35 provided on one of the rotating rail 7 and the fixed rail 6 and the other side. A hook 38 that is detachably attached to the receiver 35. When the rotary rail 7 rotates from the rotary storage position B side to the connection position A, the hook 38 is engaged in the engaging direction. The rotating rail 7 can be automatically locked by the rail locking means 10 at the connection position A, and the telescopic door body 4 is moved from the rotation storage position B to the connection position A. The operability when returning is improved.

  A spring 43 for urging the hanging tool 38 in the engaging direction is provided. When the hanging tool 38 is rotated to the connection position A on one of the receiving tool 35 side and the hanging tool 38 side, the spring 43 is resisted. By providing a guide portion for guiding the hanging tool 38 in the engagement direction and a guided portion 44 guided by the guide portion on the other side, the guide portion guides the guided portion 44 and is hung by the spring 43. The tool 38 can be reliably engaged with the receiving tool 35, and rattling or the like due to vibration of the hanging tool 38 or the like can be prevented.

  The receiving rail 35 on the fixed rail 6 side includes an engaging recess 39 in which a hook 38 on the rotating rail 7 side is engaged and disengaged from above, and an engaging guide portion provided on the rotation storage position B side with respect to the engaging recess 39. 40, and the guide portion is formed into an inclined surface shape that guides to the engaging recess 39 while lifting the hanging tool 38 when the rotating rail 7 side rotates to the connection position A, so that the receiving tool 35 and the hanging tool are provided. While simplifying the structure of 38, both can be reliably engaged.

  In addition, the rail lock means 10 is located above the moving side end frame 17 of the telescopic door body 4 in the contracted state, and is provided with an operating rod 27 that can be operated to release the hook 38 when it is lifted. Since the spring for urging the operating rod 27 to the lowered position is provided, the hanging tool 38 can be easily operated with a simple structure by the operating rod 27, and forgetting to lower the operating rod 27 can be prevented.

  Since the movement restricting means 11 does not restrict the door carts 5 other than the door cart 5a on the moving end side of the telescopic door body 4 among the plurality of door carts 5, 5a, the door carts 5, 5a are fixed between the fixed rail 6 and the rotating rail 7. When the telescopic door body 4 is expanded and contracted while traveling, the movement restricting means 11 does not get in the way and the telescopic door body 4 can be opened and closed easily.

  The movement restricting means 11 has an elastic restricting member 55 protruding downward at the upper part in the rotating rail 7, and the door 5 a on the moving end protrudes above the other door 5 and is restricted by the elastic restricting member 55. Since the restricting portion 54 is provided, it is possible to restrict only the door end 5a on the moving end side by the elastic restricting member 55, and it is also possible to restrict the central portion in the front-rear direction of the door pulley 5a by the elastic restricting member 55. .

  The elastic restricting member 55 has a restricting portion 53 disposed in the vicinity of the anti-hanging source side with respect to the door wheel 5a on the moving end side of the telescopic door body 4 in the contracted state and is made of an elastic material. The configuration of the means 11 is simple.

  The rotating rail 7 and the mounting brackets 62 fixed to both front and rear sides of the rotating rail 7 are fitted to the upper end portion of the suspension side end frame 16 so as to be inserted through the rotating rail 7 and each mounting bracket 62. An angle adjusting means 66 for adjusting the mounting angle of the rotating rail 7 is provided between the lower part of each mounting bracket 62 and the suspension side end frame 16. Therefore, the angle of the rotating rail 7 can be easily adjusted, and by adjusting the front and rear angle adjusting means 66, twisting and warping around the axis of the rotating rail 7 in the longitudinal direction can be absorbed by adjusting each angle. .

  An end frame reinforcing plate 60 that fits the rotating rail 7 and each mounting bracket 62 is provided in the upper end portion of the suspension side end frame 16, and a rail reinforcing member 61 that regulates the interval in the front-rear direction is provided in the rotating rail 7. Since the connecting shaft 63 is inserted through the end frame reinforcing plate 60 and the rail reinforcing member 61, damage and deformation of the upper end portion of the suspension side end frame 16 and the suspension rail side of the rotary rail 7 can be simplified. The rotating rail 7 can be reliably pivoted by the connecting shaft 63 while preventing.

  The connecting shaft 63 is coupled to both sides of the shaft member 63a through the end frame reinforcing plate 60 from both the front and rear sides of the suspension end frame 16 and the shaft member 63a disposed between the front and rear sides of the U-shaped end frame reinforcing plate 60. Since the pair of front and rear fixing tools 63b are provided, the rotating rail 7 and the mounting brackets 62 on both the front and rear sides thereof can be pivotally supported while fixing the connecting shaft 63 to the end frame reinforcing plate 60.

  Since the angle adjusting means 66 is provided with an adjusting screw 66a that is threadably engaged with the mounting bracket 62 and abutted against the end frame reinforcing plate 60, there is an advantage that the structure and adjustment can be easily performed.

  20-22 illustrate a second embodiment of the present invention. As shown in FIGS. 20 to 22, this hanging type extendable door includes a lower guide rail 90 such as a groove on the ground g side in addition to the upper guide rail 3, and is provided at the lower end of the extendable door body 4. A guided portion 91 that is guided along the lower guide rail 90 is provided. The guided portion 91 is configured by a rotating roller 91b rotating around a vertical axis 91a, a protrusion, or the like, and is provided on the moving side end frame 17 of the telescopic door body 4, the vertical beam 19 at the intermediate portion, and the like.

  A notch portion for separating the guided portion 91 rearward from the lower guide rail 90 so that the contracted telescopic door body 4 can rotate to the rotary storage position B on the suspension end side of the lower guide rail 90. 92 is formed on the rear wall portion 93. Other configurations are substantially the same as those of the first embodiment. In the case of such a telescopic door, it can be implemented in the same manner as described above.

  As mentioned above, although each Example of this invention was explained in full detail, this invention is not limited to these Examples, It can implement in another various aspect. For example, the telescopic door body 4 is an example in which a number of vertical bars 19 are attached to the pantograph mechanism 18, but may be one without the vertical bars 19, or a plurality of door bodies may be zigzag-shaped by the hinge means 8. It may be configured to be foldable so as to be extendable and contractible.

  The guide rail 3 and the door carts 5, 5 a are arranged along the guide rail 3 by adopting, for example, the door carts 5, 5 a provided with wheels 31 on one side of the door frame 30 and the guide rails 3 corresponding thereto. Other types may be used as long as the vehicle can travel. There may be one wheel 31 on each side or both sides of the door frame 30 or one or more wheels 31 of the door wheels 5 and 5a.

  The rail lock means 10 may be configured such that the receiving device 35 on the fixed rail 6 side faces downward, and the hanging device 38 on the rotating rail 7 side is detachably engaged with the receiving device 35 from below. In this case, if the hanging tool 38 is pushed up by the operating rod 27 on the side opposite to the receiving tool 35 with respect to the support shaft 42, the hanging tool 38 can be operated by the operating rod 27 on the moving side end frame 17 side. . Further, the receiving device 35 may be provided on the rotating rail 7 side and the hanging device 38 may be provided on the fixed rail 6 side, or the hanging device 38 may be fixed and the receiving device 35 may be movable.

  As a guide structure that relatively guides the hanging tool 38 in the engaging direction of the receiving tool 35 during the rotating operation of the rotating rail 7 to the connection position A, the inclined engaging guide section 40 illustrated in the embodiment is used. The curved guided portion 44 and the like are structurally simple. For example, a rod-shaped fixed guide portion may be provided, or after the engagement guide portion 40 and the guided portion 44 abut, Both or one of them may be operated at the time of guidance, for example, while one is lifted and engaged with the other in the engaging direction.

  As the spring 43 for urging the hook 38 in the engaging direction, a tension spring may be used in addition to the helical spring. Further, when a tension spring is used for the spring 74 that biases the operating rod 27 to the lowered position, it is arranged substantially parallel to the outside of the operating rod 27 as in the embodiment, and is incorporated inside the cylindrical operating rod 27. It is also possible. When a coil spring is used, the coil spring may be fitted around the outer periphery of the operation rod 27 or may be fitted inside the inner periphery of the operation rod 27. The springs 43 and 74 can be omitted.

  The operating rod 27 may be held at two positions, a raised position and a lowered position. In this case, in the state where the operating rod 27 is held at the raised position, the rail locking means 10 is not automatically locked even if the rotating rail 7 is returned to the connection position A, but if it is lowered to the lowered position, the same as described above. The rail lock means 10 automatically locks. Therefore, the operating rod 27 may be held at two positions, the raised position and the lowered position, or may be lowered to the lowered position by the spring 74 or its own weight when the operating force is released.

  It is most preferable that the movement restricting means 11 uses an elastic material such as a leaf spring material as in the embodiment, and the restricting portion 53 is formed on the elastic material. It is provided so as to be able to move out of and with respect to the restricted portion 54 of 5a, and is configured such that when the restricted portion 54 of the door 5a abuts against the restricting member with a predetermined force, the restricting member allows passage of the door 5a. Also good. The regulated portion 54 may use a part of the door frame 30, for example, the wheel 31.

  When the movement restriction means 11 restricts the movement of the door 5a using the wheel 31 as the restricted portion 54, the movement restriction means 11 (for example, the elastic restriction member 55) may be provided individually corresponding to the front and rear wheels 31. Alternatively, one movement restricting means 11 (for example, an elastic restricting member 55) may be provided in common on both wheels 31. Further, the front and rear wheels or the left and right wheels 31 may be restricted by the movement restricting means 11. When the wheel 31 is the restricted portion 54, the head of the hoist 32 of the door pulley 5a may have the same protruding amount as the other door wheels 32.

  Each mounting bracket 62 may have an inverted L shape or a triangular shape. Each mounting bracket 62 may protrude from the rotating rail 7 toward the suspension side, and the connecting shaft 63 may be inserted through the protruding portion of each mounting bracket 62. In this case, it is desirable that the front and rear mounting brackets 62 have their shaft insertion portions 62a in contact with each other or have a spacer or the like interposed therebetween.

  The angle adjusting means 66 is inserted between the fastening screw that passes through the lower portion of the mounting bracket 62 and is screwed into the female screw portion on the suspension end frame 16 side, and the lower portion of the attachment bracket 62 and the suspension end frame 16. It is also possible to combine with the inclusions such as wedges, adjust the mounting angle of the rotating rail 7 by inserting and removing the inclusions, and fix with the fastening screws. If the angle adjusting means 66 itself has a function of fixing the mounting bracket 62, the fastening means 67 can be simplified or omitted. It is possible to use other structures for the angle adjusting means 66.

  The door lock device 12 may cause the lock pin 46 to move between the pair of wheels 31. In that case, bidirectional movement on the rotating rail 7 side can be restricted.

  The door lock operating means 13 may have another configuration. For example, the pressed member 49 may be provided so as to protrude forward from the lock pin 46 toward the upper frame 2 or the fixed rail 6, and the pressed member 49 may be operated on the rear surface of the upper frame 2 or the fixed rail 6. Good. In this case, the rear surface of the upper frame 2 or the fixed rail 6 functions as the pressing member 50. The base of the lock pin 46 may be pivotally supported by a shaft, and may be engaged with and disengaged from the door pulley 5a by a rotational motion. In that case, the lock pin 46 may be urged by a helical spring fitted to the shaft, or may be urged by a tension spring.

  In the embodiment, the suspension type extendable door is illustrated as a double-open type in which the pair of left and right extendable door bodies 4 expands and contracts on both the left and right sides. A single-opening type in which 17 (door-end side end frame) is brought into contact with the door-end support and locked. In addition to gates, it can also be applied to various hanging-type telescopic doors used for partitions, shutters, etc.
