Description

[0001]
[Industrial applications]
The present invention provides a suspension that can easily adjust a rod suspended by two strings to be horizontal and warn a user that the rod is overloaded. The device is configured such that the warning load does not change even if it is adjusted.
[0002]
[Prior art]
Conventionally, Japanese Utility Model Laid-Open No. 6-52796 has been proposed as a hanging device of this type, but in this conventional example, a mechanism for warning that a rod is overloaded is also adjusted by adjusting the length of the string. There is no mechanism to do it.
[0003]
[Problems to be solved by the invention]
This type of hanging device is mainly attached to the ceiling in a room, and if a heavy load is applied to a rod, the device or the ceiling may be broken. It is an object to give a warning of overloading to avoid danger beforehand.
In addition, there is a case where the right and left strings are different in length due to a mistake in assembling, and the rod is not horizontal. In this case, it is necessary to disassemble and reassemble again, which is very troublesome. Therefore, at the time of assembly, the lengths of the right and left cords must be strictly aligned, which causes a problem that the assembly is troublesome and leads to an increase in cost. Also, if the length of the left and right cords is different due to long-term use and the rod is not horizontal, it is not possible to adjust the length of the rod if a general user needs to adjust the length of the rod. Therefore, the present invention has an object to solve these problems.
Another object is to provide a mechanism for warning the overload and a mechanism for adjusting the length of the string so that the load for warning does not change even if the length of the string is adjusted.
[0004]
[Means for Solving the Problems]
The present invention is a hanging device for solving the above problems, and in a hanging device capable of lifting and lowering a rod suspended by two strings, one end of each of the strings is connected to both ends of the rod. Is directly or indirectly attached to the moving tool provided in the section, and the moving tool is provided with a screw portion, screwed into a screw portion provided in the receiving device, and moved and retracted by rotating the moving tool to thereby move the rod. And the length of the cord derived from the spring can be adjusted, and the receiving member is urged forward by a spring to prevent it from falling off and can slide backward against the spring. When the cord is pulled by the string and the receptacle slides rearward via the moving tool, the receptacle changes the warning portion to the outside.
[0005]
[Action]
The rod can be adjusted horizontally by rotating the moving tool at one end or both ends of the rod to change the length of the string derived from the rod. In addition, when an excessive load is applied to the rod, the rod is lowered, and the moving device is pulled directly or indirectly by the string, and the receiving device screwed with the moving device is against the spring together with the moving device. To the rear, and the receiver changes the warning portion to the outside to warn that an excessive load is applied. In addition, even if the moving tool is moved forward and backward to adjust the length of the cord, the moving tool moves only within the receiving tool, but the receiving tool does not move, and the receiving tool changes the warning portion to warn. Therefore, there is no change in the warning load.

The locking projection 17 is provided to protrude toward the upper side, and a retaining projection 18 protruding upward is provided above the small diameter portion. The retaining projection 18 can be bent downward and is elastically restored upward. The end piece 5 has an opening 15 below the small diameter portion. The receiving piece 8 is slidably incorporated in the end piece 5.
[0009]
The receiving member 8 has a substantially cylindrical shape and is urged forward by a spring 9, is prevented from falling off at a position flush with the outer edge of the end piece 5, and can slide rearward against the spring 9. . In addition, the front is a left direction in the left end piece 5 and a right direction in the right end piece 5 in FIG. 1, that is, a direction in which the rod 3 moves outward in the longitudinal direction (outward direction). And, the rear means the opposite direction. The receiving tool 8 is provided with a screw portion 24 on the inner surface thereof, and provided with rotation stopping grooves 25, 25 so as to face each other. On the outer surface, for example, a red warning portion 23, 23 is provided on the front and back surfaces. In addition, a concave groove-shaped relief portion 26 is provided on the upper surface. The rotation stop grooves 25 are provided horizontally from the front end to the rear end, but a part of the rear end is not provided with a groove, and the rotation stop portions 22 of the attachment 7 described later come into contact with the groove. ing. The moving tool 6 is screwed into the screw portion 24 of the receiving tool 8.
[0010]
The moving tool 6 has a substantially cylindrical shape, and a screw portion 19 to be screwed into the screw portion 24 of the receiving device 8 is engraved on an outer surface thereof. 7 is engaged. The attachment 7 is provided with detent portions 22 at positions corresponding to the detent grooves 25 of the receiving member 8 and an attachment portion 21 for attaching the string 2 to the rear end face. The attachment 7 has the rotation stoppers 22 slidably engaged with the rotation stopper grooves 25 and does not rotate even when the moving tool 6 rotates, but has the rotation stopper grooves 25. The moving tool 6 is moved back and forth (longitudinal direction) within the range. Note that a screw portion may be provided in the end piece 5 and the screw portion 19 of the moving tool 6 may be screwed into the screw portion.
[0011]
To assemble this, the receiving piece 8 is inserted into the end piece 5 through the opening 15, and is moved forward to a position flush with the outer edge of the end piece 5 (it is prevented at this position), and the spring 9 is compressed. And insert it from behind the holder 8.
The string 2 suspended from the main body 1 is led out from the end through the string hole 2 of the rod 3, from the rear end of the end piece 5, from the tip through the spring 9 and the receiver 8, and the string is pulled out. 14 is tied to the attachment portion 21 of the attachment 7.
The mounting tool 7 is engaged with the rear end of the moving tool 6, and the rotation stoppers 22 of the mounting tool 7 are engaged with the rotation stopping grooves 25, 25 of the receiving tool 8 and pushed in. And screw it in until it is flush with the rear end face of the end piece 5.
Finally, when the end piece 5 is inserted from one end of the rod 3, the retaining projection 18 bends downward and restores upward by elastic force to fit into the fitting hole 13 of the rod 3, and the detent projection 17 is rotated. If it engages with the notch 12 of the rod 3, it is prevented from coming off and from rotating, and the assembly is completed.
[0012]
Then, the main body 1 is fixed to the ceiling, the rod 3 is hung by the string 2, the rotating rod 4 is hooked on the rotating part 27 of the main body 1, rotated, and the rod 3 is moved up and down for use.
[0013]
When the operating unit 20 of the moving tool 6 is turned by a driver, the moving tool 6 moves forward and backward while turning, but the mounting tool 7 moves forward and backward without turning, and the length of the cord 2 led out from the rod 3 Is changed, and the rod 3 can be adjusted horizontally.
[0014]
If an excessive load is applied to the rod 3 during use, as shown in FIG. 6, the receiving member 8 retreats against the spring 9, and the warning portions 23, 23 are exposed from the display windows 16, 16. Is warned to the user that it is overloaded. This load is the same irrespective of the adjustment position of the fixture 7, that is, whether the string 2 in FIG. 4 has the shortest dimension or the string 2 in FIG. 5 has the longest dimension. . In other words, even if the length of the cord 2 is adjusted by moving the moving tool 6 forward and backward, the moving tool 6 simply moves within the receiving tool 8 and the receiving tool 8 does not move. Since the warning is issued by changing the number 23, there is no change in the warning load. When an object is hung on the pole 3, a load greater than the weight of the object may be momentarily applied due to the impact, but the large load at that moment can be reduced by the buffering action of the spring 9. Has become.
[0015]
As another embodiment of the present invention, it is conceivable that the receiver 8 or the like sounds a buzzer as the warning unit 23 or turns on an LED as the warning unit 23. In short, it is sufficient if the warning unit 23 changes and warns the user, such as a change in the color of the display, a buzzer that does not sound, a turned off LED lights up, or the like.
[0016]
Even if the load is further applied in spite of the above warning, the fixture 7 is broken to avoid breaking the ceiling or other expensive parts of the apparatus. If the attachment 7 is broken, the retaining projection 18 is pushed in, the end piece 5 is removed, the attachment 7 is replaced with the spare attachment 11, and the assembly can be repaired by reassembling in the same manner as described above.
[0017]
