JP 2003-225498 A

  In the above conventional example, the hanging device is a hanging device that can be removed when the hanging device is rotated with respect to the support device in a suspended state, and the ring that is the hanging device is always rotated with respect to the shaft. Therefore, if the ring is rotated during attachment / detachment, for example, it is rotated beyond the range of rotation, for example, if it is not rotated normally, the hanging tool or support will be broken. There is a problem that it ends up.

  Of course, the load capacity of the hanging device is set, but it is extremely difficult for the user to know how heavy the suspended item is and whether it is within the load capacity. In such a case, there is a problem that the hanging device is broken, or in the worst case, the attached ceiling is broken.

  An object of the present invention is to solve the above two problems with a simple structure of a part.

  In order to solve the above-mentioned problem, in the invention of claim 1, in a hanging device capable of rotating and detaching a hanging tool provided with a hanging tool on a shaft to a support attached to a ceiling surface or the like. The hanging tool is provided with a connecting cylinder at the lower end portion of the shaft, and the connecting cylinder is provided with a receiving portion which is a recess opening downward, and the hooking tool is provided with a connecting protrusion at the upper end portion, and the connecting protrusion is linked. It is inserted into the housing part of the cylinder and accommodated, and is urged upward by an elastic body and attached to the lower end of the hanging tool. The coupling cylinder and the coupling projection are provided with contact parts that contact each other. A display part is provided on the outer periphery, and when the load is not applied to the hook, the contact part of the link cylinder and the link protrusion comes into contact with each other by the urging force of the elastic body, and the hook is rotated together with the shaft. The display part of the linkage protrusion is linked The hooking tool is set so as to run idle when it rotates with a force exceeding a certain level, and the elastic body biasing force is applied when a load exceeding a certain level is applied to the hooking tool. Against this, it is set so that the linking projection moves down and the display part is exposed from the linking cylinder.

  According to a second aspect of the present invention, there is provided a hanging device in which a hanging tool provided with a hanging tool on a shaft can be attached to and detached from a supporting tool attached to a ceiling surface or the like. The hook is provided with a linking projection at the lower end, the hook is provided with a linking cylinder at the upper end, and the linking cylinder is provided with a receiving portion that is a recess that opens upward. The hooking tool is suspended from the receiving portion of the linking cylinder. The connecting projection of the hanging tool is inserted and accommodated, and is biased upward by an elastic body and attached to the lower end portion of the hanging hanging tool. A display part is provided on the outer periphery of the hook, and when no load is applied to the hook, the contact portions of the link cylinder and the link protrusion come into contact with each other by the urging force of the elastic body, and the hook rotates together with the shaft. At the same time, the display part of the linking projection is housed in the linking cylinder. The hooking tool is set to rotate idly when it rotates with a certain level of force, and resists the urging force of the elastic body when a load exceeding a certain level is applied to the hooking tool. Then, the linkage cylinder is moved down so that the display portion of the linkage projection is exposed from the linkage cylinder.

The effect that an excessive force is not applied and the device is not broken and the effect of displaying an overload warning can be produced at the same time.

  In addition, even when a sudden load is applied to the hook, the elastic body that urges the hook upward may be deformed to reduce the impact load and prevent the hanging hook and the support from being broken. There is also an effect that can be done.

  The support 1 has a flange 14 on the periphery, and includes a stopper 4, a transmission tool 5, and a sorting spring 6 in a base 2 shaped like a cap with a hook upside down, and a lid on the back surface. The body 3 is covered and the surface is covered with a cover 7.

  The base 2 is provided with a guide portion 10 of a linear groove on the inner surface of the bottom plate, and a circular through hole insertion hole 9 is provided at the center of the guide portion 10. The flange portion 14 is provided with mounting holes 15 and 15 at two opposite positions, and a columnar protrusion 16 is provided in the middle. The base 2 is covered with a cover 7 in order to conceal the mounting screws inserted into the mounting holes 15 and 15 and improve the aesthetic appearance.

  In the stopper 4, a central portion is cut out in an arc shape to form a closed portion 11, and a passive portion 12 that protrudes upward is provided on the opposite side. The slidable portions 11 and 11 are slidably provided so as to face each other.

  The transmission tool 5 has a substantially short cylindrical shape and is rotatably accommodated in the base body 2, and an elliptical groove guide portion 13 is provided on one surface side, and a circular insertion recess 18 is provided at the center thereof. Furthermore, an engaging portion 19 projecting in a hexagonal shape is provided at the center of the bottom surface of the insertion recess 18. In addition, a part of the other surface is cut away to form a lower surface, and a protrusion 17 is provided on the other surface so that one end of the sorting spring 6 is attached. The other end of the distribution spring 6 is attached to the protrusion 16 of the base 2 and when the transmission tool 5 is rotated, the distribution spring 6 is distributed at the middle point.

  The passive parts 12 and 12 of the pair of stoppers 4 and 4 are adapted to engage with the guide part 13 of the transmission tool 5, and when the transmission tool 5 rotates, the engagement between the guide part 13 and the passive parts 12 and 12. Accordingly, the stoppers 4 and 4 are slid, and the blocking portions 11 and 11 block a part of the insertion hole 9 of the base 2.

  The hanging tool 8 is provided with a substantially hemispherical insertion portion 22 at one end of a shaft 20 via a spring 21, a substantially cylindrical linking cylinder 25 at the other end, and a substantially cylindrical upper portion of a ring portion 29. A hooking tool 28 provided with a columnar linkage protrusion 30 is attached. A driving portion 23 having a hexagonal hole is recessed in the flat portion at the upper end of the insertion portion 22. The drive unit 23 engages with the engagement unit 19 of the transmission tool 5.

  The linking cylinder 25 is provided with a receiving portion 26 that is a concave portion that opens downward, and a contact portion 27 that is provided with triangular projections radially on its upper surface. The link protrusion 30 is provided with a contact portion 31 having a triangular protrusion radially disposed on the upper end, and a red display portion 32 on the outer periphery of the lower portion. In this embodiment, the linkage cylinder 25 is attached separately from the shaft 20, but the lower part of the pipe-shaped shaft 20 may be a linkage cylinder. In this case, it is necessary to attach a separate contact portion of the linkage cylinder to the lower portion of the shaft 20.

  The hook 28 is attached with a screw 33 that inserts the link protrusion 30 into the housing portion 26 and penetrates the link cylinder 25, and the screw 33 is urged upward by an elastic body 24 that is a compression spring. The tool 28 is urged upward by the elastic body 24, and the contact portion 31 comes into contact with the contact portion 27 of the linkage cylinder 25 so that the respective triangular projections are engaged with each other, and the red display portion of the linkage projection 30. 32 is accommodated in the accommodating portion 26 and is not exposed.

  Between the screw 33 and the elastic body 24, there is interposed a washer made of synthetic resin between two washers 34, 34 so that the screw 33 can slide smoothly. In the present embodiment, the contact portion 27 and the contact portion 31 are both triangular projections and mesh with each other. However, if the contact portion 27 and the contact portion 31 are brought into contact with each other by the force of the elastic body 24 to generate a certain amount of frictional force. Instead of a protrusion, it may be a flat surface.

  To assemble the support 1, the stoppers 4, 4 are arranged on the guiding part 10 of the base 2 of the support 1, the passive parts 12, 12 are facing upward, and the blocking parts 11, 11 are opposed to each other, The transmitter 5 is covered so that the passive parts 12 and 12 are engaged with the guide part 13, the distributing spring 6 is attached to the protrusion 16 of the base 2 and the protrusion 17 of the transmitter 5, and the lid 3 is attached to the ceiling 3. Attach the cover 7 to the end with a mounting screw.

  The insertion part 22 of the hanging tool 8 is inserted into the insertion recess 18 of the transmission tool 5 from the insertion hole 9 of the base 2, the driving part 23 is engaged with the engagement part 19, and the hooking tool 28 is rotated 90 degrees to the right. Then, the guide part 13 of the transmission tool 5 moves the passive parts 12 and 12 of the stoppers 4 and 4, so that the stoppers 4 and 4 slide toward the center along the guide part 10, and the blocking parts 11 and 11 closes a part of the insertion hole 9. The closed insertion hole 9 becomes smaller than the diameter of the insertion portion 22, and when the drive portion 23 is removed from the engagement portion 19 and the hanging tool 8 is lowered, the insertion portion 22 is prevented from being detached by the closure portions 11 and 11. The hanging tool 8 is supported by the support tool 1 (the state shown in FIGS. 1, 2, 5, and 9).

  In a non-use state in which the hanging tool 8 is simply supported by the support tool 1, the triangular projections of the contact portion 27 of the linkage cylinder 25 and the contact portion 31 of the linkage projection 30 are engaged with each other by the force of the elastic body 24. The red display portion 32 of the linking protrusion 30 is housed in the housing portion 26 of the linking cylinder 25 and is not exposed (the state shown in FIG. 2), and a hanging tool 28, a foliage plant, a painting or the like is suspended from the hooking tool 28. It can be used by lowering it, or it can be used by attaching two spaced apart and hanging a clothes rack over the hooks 28 and 28.

  When not in use, when the hanging tool 8 is lifted by holding the hooking tool 28 and the drive part 23 of the insertion part 22 is engaged with the engaging part 19 and rotated 90 degrees to the left, the contact part of the linkage cylinder 25 is obtained. 27 and the contact portion 31 of the linking protrusion 30 are engaged with each other, the turning force is transmitted to the linking protrusion 30 and the hanging tool 8 rotates. And since the guide part 13 of the transmission tool 5 moves the passive parts 12 and 12 of the stoppers 4 and 4, the stoppers 4 and 4 slide outward along the guide part 10, and the blocking part 11 thereof. 11 retreats from the insertion hole 9, the entire insertion hole 9 opens, and the insertion part 22 of the hanging tool 8 can be removed (state of FIGS. 7, 8, and 10).

When a certain load or more is applied to the hooking tool 28 during use, the elastic body 24 is deformed via the screw 33, the hooking tool 28 is moved downward, and the display portion 32 provided on the linkage protrusion 30 is moved from the linkage cylinder 25. It is exposed and informs that it is an overload (state of FIG. 3). In this state, the contact portion 27 of the linkage cylinder 25 and the contact portion 31 of the linkage projection 30 are disengaged, and even if the hooking tool 28 is rotated, the hooking tool 8 is not rotated but dropped off. Never do.

  Further, when the hooking tool 28 is rotated, if the rotation operation is not normal, for example, the rotation is already finished and the insertion portion 22 can be attached and detached, but the rotation operation is further performed. For example, if the hooking tool 28 is forcibly rotated, the elastic body 24 is deformed, and the meshing of the triangular protrusions of the contact portion 27 and the contact portion 31 gets over and idles, so that the support tool 1 or the hanging tool. 8 is prevented from breaking.

  The hooking tool 28 is set so as to run idle when rotated with a force exceeding a certain level. When a load exceeding a certain value is applied to the hooking tool 28, the linkage protrusion 30 moves downward against the urging force of the elastic body 24. Then, the display unit 32 is set to be exposed from the linkage cylinder 25, but the force at which the hook 28 starts to idle and the force at which the display unit 32 is exposed from the linkage cylinder 25 are determined by the strength of the elastic body 24. The contact portion 27 and the contact portion 31 are determined according to how they mesh with each other, and are not necessarily the same.

  In addition, what is shown in FIG.11 and FIG.12 is another Example of the hanging tool 101, Comprising: A linkage cylinder and a linkage protrusion are reversed. A substantially cylindrical linking projection 106 is provided at the lower end of the shaft 102, and a hook 103 having a substantially cylindrical linking cylinder 109 provided at the upper portion of the ring portion 104 is attached thereto.

The connecting projection 106 is provided with a contact portion 107 having triangular projections radially arranged at the lower end and a red display portion 108 on the outer periphery of the intermediate portion.

  The hook 103 is attached with a screw 112 inserted into the housing portion 110 of the linkage tube 109 and passing through the linkage projection 106, and the screw 112 is urged upward by an elastic body 105 which is a compression spring. Therefore, the hook 103 is urged upward by the elastic body 105, the contact portion 111 comes into contact with the contact portion 107 of the linkage projection 106, and the respective triangular projections mesh with each other. The red display unit 108 is accommodated in the accommodating unit 110 and is not exposed (state shown in FIG. 11).

  When a load of a certain level or more is applied to the hooking tool 103, the elastic body 105 is deformed via the screw 112, the linkage cylinder 109 provided on the hooking tool 103 is moved down, and the display unit 108 provided on the linkage protrusion 106 is It is exposed and informs that it is an overload (state of FIG. 12).
