The invention described in claim 2 is a hanging device in which a hanging device is attached to the bottom of each of a pair of supports attached to the ceiling or the like in a room, and both ends of a hanging rod are attached to the lower ends of the hanging devices, and the lower ends of the supports are inserted into a cylindrical part that opens upward and is attached with a mounting screw, and the supports are provided with engaging protrusions, and the inner surface of the cylindrical part of the hanging device is provided with engaging parts, so that if the mounting screws loosen or break, the engaging protrusions engage with the engaging parts to prevent the device from falling. [Effects of the Invention]

[0007] As described above, according to the invention described in the claims, when the mounting screw attaching the suspension device loosens or breaks, the engaging protrusion engages with the engaging portion, preventing the device from falling and thus avoiding danger. [Brief explanation of the drawings]

[Figure 5] FIG. 2 is an exploded perspective view showing the state in which the support tool of the first embodiment is attached to a ceiling surface (when attached to plywood G). [Figure 6] FIG. 2 is a perspective view showing a state in which a part of the support tool of the first embodiment is cut away. [Figure 7] FIG. 10 is an exploded perspective view showing a connecting portion between a support tool and a suspending tool according to a second embodiment.

[0009] A first embodiment of the present invention will be described with reference to FIGS. The hanging device has a pair of support members 1·1 attached to the ceiling C, each of which has a pair of hanging members 2·2 attached to its tip, and both ends of a hanging rod 3 are attached to the tip of each member via connectors 4·4, and the hanging rod 3 is used to hang hangers or the like on which laundry is hanging.

[0010] The support 1 is composed of a rectangular cylindrical tubular portion 8 erected from the center of the surface of a roughly rectangular plate-shaped base portion 7, and the base portion 7 has three mounting holes 9···9 at the front and rear ends, respectively, and the cylindrical portion 8 has a mounting hole 12 at the bottom of the front plate, a mounting hole 13 in the middle of the inner side plate, and an operation window 14 adjacent to that. As shown in Figure 6, a sliding groove 24 is provided on the inner surface of the inner face plate of the cylindrical portion 8, extending in a substantially vertical straight line from the top to the operation window 14, along which the engaging protrusion 17 described below slides, and an engaging portion 25 is provided at the terminal end of the lower end of the groove, with which the engaging protrusion 17 abuts and engages.

[0011] Hanging device 2 is cylindrical with a roughly rectangular cross section, and its upper end is inserted into cylindrical portion 8 of support device 1 to be attached. In the attached state, threaded hole 15 is provided at a position corresponding to mounting hole 12 in cylindrical portion 8, and threaded hole 16 is provided at a position corresponding to mounting hole 13 in cylindrical portion 8. Furthermore, cylindrical pin-shaped engagement protrusion 17 is attached at a position corresponding to above operation window 14 within sliding groove 24 on the inner surface of the inner face plate of cylindrical portion 8, and is biased by a spring so as to be able to freely move in and out. Furthermore, an orange sheet-like display unit 18 is attached to the inside surface of suspending tool 2 at a position below threaded hole 16.

[0012] The suspension device 2 is attached to the support device 1 by inserting its upper end into the cylindrical portion 8 of the support device 1 from below while retracting the engagement protrusion 17 against the spring force, and then raising it until the mounting hole 12 and the threaded hole 15, and the mounting hole 13 and the threaded hole 16 are aligned, and then threading the mounting screw 10 into the threaded hole 15 from the mounting hole 12, and threading the mounting screw 11 into the threaded hole 16 from the mounting hole 13. At this time, while suspending tool 2 is being inserted into cylindrical portion 8 and raised, engaging protrusion 17 protrudes by the force of the spring when it is positioned at the bottom of sliding groove 24 (position of operation window 14), and further slides upward within sliding groove 24. Then, in the attached state, engaging protrusion 17 is in a state of protruding into sliding groove 24 at a position above operation window 14, and display unit 18 is hidden within cylindrical portion 8 and is not exposed.

[0013] When the hanging device 2 is attached to the ceiling C and in use, if the mounting screws 10 and 11 loosen or break and the hanging device 2 falls, the engaging protrusion 17 comes into contact with and engages with the engaging portion 25 at the terminal end of the lower end of the sliding groove 24, thereby preventing the hanging device 2 from falling. When this state occurs, the display unit 18 is exposed from the cylindrical portion 8 to warn that the mounting screws 10 and 11 have loosened or broken, causing the engaging protrusion 17 to engage with the engaging portion 25 at the lower end of the sliding groove 24, creating a dangerous situation.

[0014] In this state, engagement protrusion 17 is visible from operation window 14, and by pressing engagement protrusion 17 against the spring and retracting it from operation window 14, suspension tool 2 can be removed.

[0015] Connector 4 at the lower end of suspending tool 2 is attached so as to protrude inward, has a generally inverted U-shaped cross section that opens upward, and has two cylindrical screw holes 22·22 that also open upward formed in its bottom surface. Connector 4·4 is attached to the pair of suspending tools 2·2 so as to face each other and face inward.

[0016] The hanging rod 3 has a roughly rectangular cross section, and mounting fixtures 5, 5 separate from the hanging rod 3, are attached to both ends with mounting screws 19, 19 so that they protrude outward. The mounting fixture 5 has a roughly inverted U-shaped cross section that opens downward, and mounting holes 21, 21 are provided on the top surface at positions that correspond to the screw holes 22, 22 of the connecting fixture 4. The fixtures 5·5 may be provided integrally at both ends of the hanging rod 3, rather than being separate components attached to the hanging rod 3 as in this embodiment.

[0017] Next, two methods for attaching this suspension device to the ceiling C will be explained. First, as shown in FIG. 4, when attaching the suspension device to the joist N behind the ceiling C, one of the support devices 1 is placed in a position corresponding to the joist N behind the ceiling C and fixed by screwing in mounting screws 23·23 through the central mounting holes 9·9, the other support device 1 is similarly fixed to another joist (not shown) at a predetermined distance, the upper end of one of the suspension devices 2, which has connecting device 4 already attached to its lower end, is inserted into tubular portion 8 of support device 1 from below, and suspension device 2 is attached to support device 1 with mounting screws 10 and 11, and the other suspension device 2 is attached to support device 1 in the same way.

[0018] Next, place the mounting fixtures 5·5 at both ends of the hanging rod 3 so that they fit inside the connecting fixtures 4·4, allowing you to work hands-free. Then, thread the mounting screws 20·20 from above through the mounting holes 21·21 of one of the mounting fixtures 5 into the threaded holes 22·22 of the connecting fixture 4 to secure it, and do the same for the other mounting fixture 5 to secure it to the connecting fixture 4. Finally, fit caps 6·6 onto the mounting fixtures 5·5 on both the left and right sides to hide the mounting screws 20·20, and the installation is complete.

[0019] In this way, if the work of tightening the mounting screws 20 can be done from the upper side of the mounting fixture 5, it is easy to apply force and the work is easy to do. Furthermore, if the screw is screwed from the lower connecting tool 4 side, there is a risk that the mounting tool 5 may be pushed up and cause an accidental fall, but this risk can be avoided. Furthermore, when attached, the hanging rod 3 can be aligned almost in a straight line with both the left and right caps 6·6 and the connectors 4·4 without any irregularities, resulting in a good appearance.

[0020] Next, as shown in Figure 5, to attach this hanging device to the plywood G behind the ceiling C, place the support 1 in a position corresponding to the plywood G behind the ceiling C and secure it in place with mounting screws 23···23 in the front and rear mounting holes 9···9. The rest of the installation method is the same as for the rough frame N described above.

[0021] Another embodiment (second embodiment) of the connecting portion between support device 101 and suspending device 102 of the present invention will be described with reference to FIG. The support 101 is composed of a rectangular cylindrical upright portion 104 standing upright from the center of the surface of a substantially rectangular plate-shaped base portion 103, the base portion 103 having three mounting holes 111...111 at the front and rear ends, the upright portion 104 having a screw hole 105 at the top of the front plate and a screw hole 106 at the middle of the inner side plate, and a cylindrical pin-shaped engagement protrusion 107 is attached diagonally below the screw hole 106 and biased by a spring so as to be able to freely protrude and retract. Furthermore, an orange sheet-like display portion 110 is attached to the upper position of the inner surface of the upright portion 104 of the support 101.

[0022] Suspension device 102 has a square-tubular tubular portion 112 into which upright portion 104 of support device 101 is inserted for attachment, and in the attached state, attachment hole 113 is provided at a position corresponding to screw-engagement hole 105 of upright portion 104, and attachment hole 114 is provided at a position corresponding to screw-engagement hole 106 of upright portion 104. Furthermore, a vertically elongated sliding hole 115 is provided horizontally adjacent to the mounting hole 114, and an engagement portion 116 is provided at the upper terminal end of the sliding hole 115.

[0023] The hanging device 102 is attached to the support device 101 by inserting the upright portion 104 of the support device 101 from above into the cylindrical portion 112 of the support device 101 while retracting the engaging protrusion 107 of the support device 101 against the spring force, and then raising the hanging device 102 until the mounting hole 113 and the threaded hole 105, and the mounting hole 114 and the threaded hole 106 are aligned, and then threading the mounting screw 108 into the threaded hole 105 from the mounting hole 113, and threading the mounting screw 109 into the threaded hole 106 from the mounting hole 114. At this time, while suspending tool 102 is being raised, engaging protrusion 107 protrudes by the force of the spring when it is positioned at the top of sliding hole 115, and further slides downward within sliding hole 115. Then, in the attached state, engaging protrusion 107 is in a protruding state at the bottom end of sliding hole 115, and display unit 110 is hidden within cylindrical portion 112 of suspending tool 102 and is not exposed.

[0024] Then, if mounting screws 108 and 109 loosen or break and suspending device 102 falls while attached to ceiling C, engaging portion 116 at the upper end of sliding hole 115 abuts against and engages with protruding engaging projection 107, preventing the device from falling. When this state occurs, display unit 110 is exposed from cylindrical portion 112 of suspension tool 102 to notify and warn of the danger that mounting screws 108 and 109 have loosened or broken, causing engaging protrusion 107 to engage with engaging portion 116 at the upper end of sliding hole 115.

[0025] In this state, if engaging projection 107, which is visible from slide hole 115, is pressed against the spring and retracted, suspending tool 102 can be removed downward. [Explanation of symbols]
