Description

The present invention relates to a shaft mounting member that supports a shaft vertically on a mounting surface such as a ceiling surface, and to a suspender and hanging device that use the same.

For example, a hanging device is known in the past that supports a hanger pipe, such as a clothesline pole, approximately horizontally on a shaft that is attached to a target surface such as a ceiling and hangs down. Also known is a sling that has a ring-shaped hanging ring at the end of a shaft that is attached to a target surface and hangs down, and that suspends a hanger or other suitable object to be hung from the ring. One end of the shaft in such hanging devices or slings is attached to the target surface by some kind of mounting member.

In this case, if the shaft is firmly fixed to the mounting member that is fixed to the mounting surface, when an external force is applied from the side to the hanging shaft, load is placed on the mounting surface (such as the ceiling surface) to which it is fixed and on the mounting member, which may accelerate the deterioration of these. Also, since it is best for users to avoid bumping into things as much as possible, they may be very careful to avoid doing so.

In response to this, a technique is known in which a shaft is supported so as to be freely swingable relative to a mounting member that is fixedly attached to the mounting surface (see, for example, Patent Document 1). When a shaft ("hanging rod 5" in Patent Document 1) is hanging down so as to be freely swingable from the mounting surface, if an object to be hung ("dry hanger 11" in Patent Document 1) is hung from the lower end of the shaft or from a hanger pipe supported by the shaft, the shaft (or even the "hanger pipe") will swing and become unstable, making it difficult to perform the hanging operation. In addition, there is a concern that the application of some kind of lateral force to the shaft will cause the object to be hung to swing together with the shaft (or even with the "hanger pipe"), possibly hitting a surrounding wall, window, etc.

In this embodiment, up and down means up and down in the direction of gravity, and "horizontal" or "horizontal plane" means a plane perpendicular to the direction of gravity. However, "horizontal" and "horizontal plane" do not have to be exactly perpendicular to the direction of gravity, and the concept includes not only planes that can be said to be approximately horizontal, but also planes that are somewhat inclined, as long as the inclination is sufficient to realize the present invention.

The shaft mounting member (hereinafter sometimes simply referred to as the "mounting member") 1 of this embodiment supports the shaft 2 in a hanging state on a ceiling surface 3, which is an example of a mounting target surface. Note that in the present invention, the mounting target surface is not limited to a ceiling surface, and may be any horizontal surface facing downward on a member or part capable of supporting a shaft, such as a beam or lintel of a structure, an attic, or the top surface inside furniture.

As shown in Figures 1 to 4, the mounting member 1 of this embodiment specifically includes a base 11 that is attached to the ceiling surface 3, a joint 12 that supports one end (upper end) of the shaft 2 from below, a hinge 13 fixed to the upper side of the joint 12, a hinge cover 15 fixed to the base 11, a pivot 14 having shaft portions 141, 143 and a curved tip portion 142, and a coil spring 16 that biases the pivot 14 toward the base 11.

The base 11 has a disk-shaped base 111 and a cylindrical portion 112 that rises downward on its center. The base 111 has four screw holes 115 at equally spaced positions in the circumferential direction and in point symmetry with respect to a point on the axis X as the center. Wood screws (not shown) are passed through these holes and screwed into the ceiling surface 3, fixing and attaching the base 11 to the ceiling surface 3.

On the inner periphery of the cylindrical portion 112 on the underside of the base 111 (the underside facing downward), there is an annular flat surface 113, and a recess 114 is provided in the center of the annular flat surface 113. On the outer periphery of the cylindrical portion 112 of the base 111, and further inward than the area in which the four screw holes 115 are located, four bolt holes 116 are provided at positions that are point symmetric and equally spaced in the circumferential direction.

The hinge 13 has a cylindrical portion 131 that protrudes upward in the direction of axis X from the joint 12, and a curved protruding portion 132 that is connected to the cylindrical portion 131 and has a part of its outer circumferential surface that is spherical with a center point O that overlaps with the central axis (the same as the axis X) of the cylindrical portion 131. The hinge 13 also has a hole portion 133 that recesses downward from the upper end of the curved protruding portion 132 in the direction of axis X, and a screw hole 134 provided at the lower end of the cylindrical portion 131.

The hole 133 in the hinge 13 has a large inner diameter section 135 on the upper side in the axial direction, a small inner diameter section 136 below the large inner diameter section 135 and having a smaller inner diameter than the large inner diameter section 135, and an inner diameter step section 137 connecting the large inner diameter section 135 and the small inner diameter section 136. The large inner diameter section 135 and the small inner diameter section 136 are cylindrical cavities with the axis X as their central axis, and extend from the upper end of the hinge 13 to a region below the center in the axial direction. The small inner diameter section 136 is connected below the large inner diameter section 135 and has a shorter length in the axial direction than the large inner diameter section 135.

The shafts 141, 143 of the pivot 14 have a large outer diameter section 143 on the upper side in the axial direction, a small outer diameter section 141 on the lower side of the large outer diameter section 143, and an outer diameter step section 144 connecting the large outer diameter section 143 and the small outer diameter section 141. The large outer diameter section 143 has an outer diameter that allows it to fit into the large inner diameter section 135 in the hole section 133 of the hinge 13 and to move in the axial direction. On the other hand, the small outer diameter section 141 has an outer diameter that allows it to fit into the small inner diameter section 136 in the hole section 133 of the hinge 13 and to move in the axial direction.

The pivot 14 and coil spring 16 are housed in the hole 133 of the hinge 13. More specifically, the small outer diameter portion 141 of the shaft of the pivot 14 is inserted into the coil spring 16, and is housed in the hole 133 in a compressed state. One end of the coil spring 16, the upper end 161, abuts against the outer diameter step 144, and the other end, the lower end 162, abuts against the inner diameter step 137.

The hinge cover 15 has a ring portion 153 with a circular opening 156, a cylindrical tubular portion 152 rising upward from the outer periphery of the ring portion 153, and an annular flange portion 151 projecting outward at the upper end of the tubular portion 152. The flange portion 151 has four screw holes 154 at equally spaced positions circumferentially and point-symmetrically centered on a point on the axis X, and bolts 155 pass through these holes and are screwed into the bolt holes 116 of the base 11 to fix the hinge cover 15 to the base 11.

The diameter of the circular opening 156 in the hinge cover 15 is smaller than the diameter of the sphere on the outer circumferential surface of the curved protrusion 132 and larger than the diameter of the cylindrical portion 131. The hinge cover 15 holds the hinge 13 by fitting the cylindrical portion 131 into the circular opening 156, with the curved protrusion 132 positioned above (one side) the circular opening 156 and the cylindrical portion 131 positioned below (the other side).

The outer peripheral surface of the curved protrusion 132 of the hinge 13 comes into contact with and can rub against the opening edge 156' of the circular opening 156. Therefore, the outer peripheral surface of the curved protrusion 132 of the hinge 13 rubs against the opening edge 156' of the circular opening 156, so that the central axis of the hinge 13 can be tilted at an angle from the axis X, i.e., can be swung, with point O as the center point.

The central axis of the hinge 13 can be tilted around point O at a certain angle (θ° in FIG. 5, described later) from axis X. However, the direction of tilt is allowed to any angle of 360° due to the structural characteristics of the combination of the circular opening 156 and the curved protrusion 132.

The inner diameter of the opening edge 156' of the circular opening 156 has a tapered shape that gradually expands from the lower end to the upper end. Therefore, the opening edge 156' is in surface contact with the outer circumferential surface of the curved protrusion 132, and is able to firmly support the hinge 13 (and further the joint 12 and shaft 2 supported by it, etc.).

From the viewpoint of stable support of the hinge 13, it is more preferable that the inner shape of the opening edge 156' of this circular opening 156 be a curved shape that corresponds to the outer peripheral surface of the curved projection 132 (when we say "corresponding curved shape," we mean a wide range of curved shapes, from shapes that completely copy to shapes that almost copy).

The hinge cover 15 is fixed to the base 11 with its upper side (one side) facing up. Then, as shown in FIG. 2, the curved protrusion 132 of the hinge 13, the coil spring 16, and most of the pivot 14 are contained within the space surrounded by the base 11 and the hinge cover 15.

In the mounting member 1 according to this embodiment, the "connection portion" of the present invention is constituted by the hinge 13 and the hinge cover 15 (hereinafter referred to as the "connection portion 13, 15"). The connection portion 13, 15 constituted by the hinge 13 and the hinge cover 15 connects the joint 12 and the base 11 in a state in which the shaft 2 and the joint 12 can swing about a fulcrum point O located below the bottom surface of the base 11.

The pivot 14 housed in the hole 133 of the hinge 13 has an axial tilt that is consistent with the hinge 13, the joint 12 to which the hinge 13 is fixed, and the shaft 2 attached to the joint 12. Therefore, the axes of the shafts 141 and 143 of the pivot 14 are designed to tilt in accordance with the swinging of the joint 12, etc.

The coil spring 16 sandwiched between the outer diameter step 144 and the inner diameter step 137 is maintained in a compressed state. Therefore, the pivot 14 is in contact with the bottom surface of the base 11 with its tip 142 biased against it. The elastic force of the compressed coil spring 16 attempting to expand acts to bias the tip 142 of the pivot 14 against the bottom surface of the base 11.

A recess 114 is provided at the location where the tip 142 abuts on the underside of the base 11, and the tip 142 of the pivot 14 fits into the recess 114. In other words, the tip 142 of the pivot 14 fits into the recess 114, and the hanging state of the components below the hinge 13 (joint 12, shaft 2, etc.) is stably maintained.

The joint 12 is cylindrical and has one opening 122 facing downward and the other opening 123 facing upward. In detail, the joint 12 is composed of an outer tube portion 121 that forms the outer peripheral surface, an inner tube portion 128 that is folded back at the upper end and formed inside the outer tube portion 121, and a bottom portion 129 that closes the lower end of the inner tube portion 128 that ends just before the lower end of the outer tube portion 121 in the axial X-line direction.

The inner circumferential surface continuing from the opening 123 is the inner circumferential surface of the inner cylinder portion 128, and the inner circumferential surface continuing from the opening 122 is the inner circumferential surface of the outer cylinder portion 121. The cylindrical portion 131 is fitted into the opening 123 to fix the hinge 13, and one end (upper end) of the shaft 2 is fitted into the opening 122 to support it.

In particular, a slit is formed between the inner peripheral surface of the outer tube portion 121 and the outer peripheral surface of the inner tube portion 128, forming an insertion port 122' into which the pipe of the shaft 2 is inserted. The slit of this insertion port 122' has the folded-back portion of the outer tube portion 121 and the inner tube portion 128 at its upper end, against which the upper end of the inserted shaft 2 abuts, thus serving as a positioning means for the shaft 2.

A screw hole 126 is formed in the bottom 129 of the joint 12, centered on the axis X. A screw 127 is inserted through this screw hole 126 and screwed into the screw hole 134, thereby fixing the hinge 13 to the upper side of the joint 12. The hinge 13 and the joint 12 are fixed to each other before the shaft 2 is inserted into the opening 122 of the joint 12 (inserted into the insertion hole 122').

The outer tube 121 of the joint 12 has a hole 124 with a female screw groove formed on its inner circumferential surface. The hole 124 is provided in a cylindrical protrusion 124' that rises from the outer surface of the outer tube 121 to ensure the length of the female screw groove. The hole 124 is drilled toward the shaft 2 that is inserted into the opening 122. A male screw 125 with a male screw groove that screws into the female screw groove formed in the hole 124 is screwed into the hole 124.

When one end of the shaft 2 is fitted into the opening 122 in the joint 12 (inserted into the insertion opening 122') and the male screw 125 is screwed into the hole 124, its tip protrudes from the inner circumferential surface of the outer tube 121 and presses against the circumferential surface of the shaft 2. The pressing force of the male screw 125 fixes and supports one end (upper end) of the shaft 2 to the joint 12.

Figures 1 and 3 show the shaft 2 attached to the mounting member 1 of this embodiment and supported in a hanging state under normal conditions. For example, when used as a sling or hanging device as described below, a force pushing or pulling in the forward and backward directions is applied when suspending an object, and a lateral external force may act on the shaft 2. The mounting member 1 of this embodiment allows the shaft 2 supported in a hanging state to tilt diagonally when a load is applied laterally, but when there is no load from the side, the shaft 2 is easily maintained in a hanging state.

Hereinafter, the operation and effect of this embodiment, in which the shaft 2 is capable of tilting obliquely but is likely to maintain a drooping state when there is no lateral load, will be described with reference to FIG. 5.
5A and 5B are longitudinal cross-sectional views showing a state in which a lateral external force acts (a load is applied from the lateral direction) on the shaft 2 attached to the shaft mounting member 1 of this embodiment, where (a) shows a state in which an external force acts from right to left, and (b) shows a state in which an external force acts from left to right.

When an external force acts from right to left, as shown in Figure 5(a), the shaft 2 is pushed to the left and tends to tilt diagonally. The mounting member 1 to which the shaft 2 is fixed also tends to tilt in the same direction as the shaft 2, but as described above, the outer peripheral surface of the curved protrusion 132 rubs against the opening edge 156' of the circular opening 156, causing the central axis of the hinge 13 to tilt at an angle from the axis X.

At this time, the elastic force of the compressed coil spring 16 acts to bias the tip 142 of the pivot 14 while it is fitted into the recess 114, and there is a threshold value for the magnitude of the external force (load) required for the tip 142 of the pivot 14 to escape from the recess 114. When the external force applied from right to left exceeds this threshold value and the tip 142 of the pivot 14 begins to escape from its original position to the right, the central axis of the hinge 13 tilts at an angle from the axis X. The external force from right to left on the shaft 2 is attenuated by the strength of the external force required to exceed this threshold value.

Therefore, when an external force acts from right to left, the above action allows the axis of the shaft 2 in this embodiment to tilt obliquely from the axis X in the hanging state to the tilted axis Xa, as shown in Figure 5 (a). This reduces the load from the side, and suppresses its effects.

In addition, when an external force exceeding a threshold load is applied to the tip 142 of the pivot 14 from being inserted into the recess 114, the pivot 14 and shaft 2 tilt at that moment, giving a clicking sensation. Therefore, when the user feels the clicking sensation, he or she can recognize that excessive or strong force has been applied in the lateral direction.

On the other hand, when the external force that had been acting is eliminated and the lateral load is released, a biasing force acts on the tip 142 of the pivot 14, which has been displaced from its original position to the right, in the recess 114 due to the elastic force of the coil spring 16. Gravity also acts to return the shaft 2 and hinge 13, etc., to a vertical state. The biasing force of the elastic force of the coil spring 16 and the gravity that returns the shaft 2 and hinge 13, etc., to a vertical state return the shaft 2 to its position on the axis X in a hanging state.

When the shaft 2 returns to the position on the axis X in the drooping state, the user can feel a clicking sensation as the tip 142 of the pivot 14 fits into the recess 114. In addition, unless an external force exceeding a threshold load is applied, the tip 142 of the pivot 14 will not deviate from the state in which it is fitted into the recess 114, so that the shaft 2 is likely to remain in the drooping state when there is no lateral load.

On the other hand, when an external force acts from left to right, the shaft 2 can tilt obliquely in the opposite direction to the case shown in Figure 5(a) above. Although detailed operation is omitted, in this case, as shown in Figure 5(b), the outer peripheral surface of the curved protrusion 132 rubs against the opening edge 156' of the circular opening 156, and the central axis of the hinge 13 is tilted at an angle from the axis line X.

Then, when the external force acting from left to right is released and the lateral load is released, the elastic force of the coil spring 16 and the force of gravity that causes the shaft 2 and hinge 13 to return to a vertical state return the shaft 2 to its hanging position on the axis X.

In the explanation of FIG. 5, for convenience, a case where a lateral external force acts from directions that differ by 180° to the left and right (opposite directions) is illustrated as an example, but the present invention is not limited to this. In other words, in the mounting member 1 of this embodiment, which is configured so that the hinge 13 can be freely tilted at any angle relative to the hinge cover 15 by the spherical curved protrusion 132 and the circular opening 156, the axis of the shaft 2 can be tilted diagonally in the same way even if the shaft 2 receives an external force from any lateral direction of 360°.

Therefore, even if a lateral external force acts on the shaft 2, for example, due to a person bumping into it, the axis of the shaft 2 tilts diagonally, mitigating the effect of the external force. Then, after the external force is eliminated and the lateral load is removed, the shaft 2 returns to a hanging state due to the action of the elastic force of the coil spring 16 and the action of gravity that returns the shaft 2 and hinges 13, etc., to a vertical state.

The angle between the axis X in the hanging state and the axis Xa in the tilted state, i.e., the maximum value of the tilt angle θ of the axis of the shaft 2 (see Figures 5(a) and 5(b)), is determined by various conditions such as the relationship between the size and shape of the curved protrusion 132 and the circular opening 156, the distance between the curved protrusion 132 and the upper end of the joint 12 (interference state between the two), and the space enclosed by the base 11 and the hinge cover 15.

By increasing the maximum value of the inclination angle θ of the shaft 2, it is possible to increase resistance to external forces from the side. Increasing the maximum value of the inclination angle θ of the shaft 2 tends to increase the size of the mounting member 1, so it is preferable to design it appropriately within a practical range. There is no preferred range or restriction for the maximum value of the inclination angle θ of the shaft 2, but it is selected from the range of approximately 1° to 20°.

The strength of the clicking sensation when the tip 142 of the pivot 14 is released from its inserted state in the recess 114, or when it is inserted from its released state, can be adjusted by adjusting the elastic force of the coil spring 16, controlling the relationship between the shape of the tip 142 of the pivot 14 and the recess 114, etc.

The clicking sensation can be made stronger by using a coil spring 16 with stronger elasticity or by using it in a more compressed state. Conversely, the clicking sensation can be made weaker by using a coil spring 16 with weaker elasticity or by using it in a less compressed state.

The clicking sensation can be made stronger by fitting the tip 142 of the pivot 14 and the recess 114 tightly together under normal conditions (when the shaft 2 is in a hanging state) and requiring a step to be overcome when departing. The clicking sensation can also be made stronger by making the step larger and steeper. Conversely, the clicking sensation can be made weaker by loosening the fit between the tip 142 of the pivot 14 and the recess 114 under normal conditions, making the step when departing more gradual, or even making it slope-shaped without a step.

In the shaft mounting member 1 of this embodiment, the shaft 2 is detachable (can be attached and removed freely). Therefore, by simply preparing the same mounting member 1 (including all cases including attaching the mounting member to the mounting surface in advance, preparing a single mounting member that does not include a shaft in the lineup of products to be sold, and even preparing multiple types of sets of a single mounting member and different types of shafts), it is easy to combine with shafts of different lengths, shapes, etc., or to change them.

The mounting member 1 of the present embodiment described above can itself be used as a hanging device, for example, by attaching a shaft having a ring-shaped hanging ring portion at its lower end or midway to a ceiling surface 3, etc.
Fig. 6 is a front view showing an example of a suspender using the mounting member 1 according to the present embodiment. Fig. 7 is a vertical cross-sectional view taken along a plane including the central axis of the suspender using the mounting member 1 according to the embodiment of the present invention.

As shown in Figures 6 and 7, it has a mounting member 1 and a shaft 2 having one end supported by the mounting member 1, and the other end (lower end) of the shaft 2 is provided with a hanging ring portion 7 for hanging an object, so that it can be used as a hanging device.
The hanging ring part 7 is composed of a cylindrical fixing part 71 and an annular part 72 fixed to the lower end of the cylindrical fixing part 71. The upper part of the fixing part 71 is open, and the lower end of the shaft 2 is inserted and stopped at the closed lower end to be positioned.

The fixing part 71 has two holes 714a, 714b with female thread grooves formed on the inner circumferential surface, similar to the hole 124 in the outer tube part 121 of the joint 12. The holes 714a, 714b are drilled toward the shaft 2 that is fitted into the fixing part 71. Male screws 715a, 715b with male thread grooves that screw into the female thread grooves formed in the holes 714a, 714b are screwed into the holes 714a, 714b, respectively.

Near the lower end of the shaft 2, a constricted portion 25 is formed that is recessed and narrowed around the entire circumference, and a neck portion 26 is formed from the constricted portion 25 to the lower end, and has the same diameter as the straight pipe portion 21 above the constricted portion 25. When the lower end of the shaft 2 inserted into the fixing portion 71 is positioned by abutting against the closed lower end, the constricted portion 25 is positioned opposite the tip of the male thread 715a.

In this state, when the male screws 715a and 715b are screwed into the holes 714a and 714b, their tips protrude from the inner circumferential surface of the fixing part 71 and press against the circumferential surface of the shaft 2. The pressing force of the male screws 715a and 715b fixes the fixing part 71 to the lower end of the shaft 2, and the hanging ring part 7 is provided on the shaft 2.

At this time, the tip of the male screw 715a screwed into the hole 714a protrudes and fits into the necked portion 25 of the shaft 2, pressing against the shaft 2 and firmly fixing the fixing portion 71 so that no up and down movement occurs. Meanwhile, the tip of the male screw 715b screwed into the hole 714b protrudes against the outer circumferential surface of the straight tube portion 21 of the shaft 2 and presses against and holds down the shaft 2. In other words, the male screw 715a restricts the up and down movement of the hanging ring portion 7, while the male screw 715a and the male screw 715b fix the entire hanging ring portion 7 to the shaft 2.

The hanging device configured as described above can be used by hanging, for example, a clothes or laundry hanger, or one end of a clothesline pole 8 as shown in FIG. 7, from the annular portion 72 of the hanging ring portion 7 attached to the shaft 2. When using it to hang a clothesline pole 8, another hanging device can be prepared to make a pair, and both ends of the clothesline pole 8 can be hung from the annular portion 72 of the hanging ring portion 7 to bridge them.

The hanging device in the example of Figures 6 and 7 allows the shaft 2 to tilt diagonally when a lateral external force acts on the object being hung, such as clothing or a clothesline pole 8, or on the shaft 2. Therefore, the entire hanging device bends diagonally relative to the surface to which it is attached, such as the ceiling surface, reducing the lateral load and suppressing its effects.

In addition, with the sling examples shown in Figures 6 and 7, when an external force exceeding the threshold load required to tilt the shaft 2 etc. is applied, the user feels a clicking sensation, enabling the user to recognize that excessive or strong force has been applied to the shaft 2 etc. in the lateral direction.

Then, when the applied external force is released and the lateral load is removed, shaft 2 returns to the hanging position, and the entire sling returns to its normal shape (a shape in which the entire sling is not bent).
A clicking sensation can also be given to the user when the shaft 2 returns to the position on the axis X in the drooping state. In addition, since the shaft 2 will not tilt unless an external force exceeding a threshold load is applied laterally, the drooping state of the shaft 2 is easily maintained when there is no lateral load.

In the hanging device shown in the examples of Figures 6 and 7, the hanging ring 7 is provided only at the lower end of the shaft 2, but the hanging device using the shaft mounting member of the present invention is not limited to this. In other words, the hanging ring may be provided at two or more locations in total, at the lower end of the shaft and at one or more intermediate locations, or may be provided only at one or more intermediate locations.

Furthermore, the mounting member 1 according to this embodiment can be used together with the shaft 2 as a component for supporting a hanger pipe as part of a so-called hanging device.
FIG. 8 is a perspective view showing an example of a hanging device 100 using the mounting member 1 according to this embodiment.

8, the hanging device 100 comprises a hanger pipe 5 for hanging objects, a pair (two pieces) of mounting members 1 according to this embodiment, a pair (two pieces) of shafts 2, one end of which is supported by each mounting member 1, and a pair (two pieces) of connecting members 4 that support the end of the hanger pipe 5 at the lower end of each shaft 2. The pair of connecting members 4 support both the left and right ends of the hanger pipe 5 and hold it approximately horizontally.
The pair of mounting members 1, the shaft 2 and the connecting members 4 are identical in configuration, and therefore, for convenience, one of them will be described below.

The mounting member 1 has a base 11 that is attached to the ceiling surface 3, which is the mounting surface, with wood screws or the like, and one end of the shaft 2 is inserted into the joint 12 to support it. In other words, the mounting member 1 of this embodiment attaches the shaft 2 to the ceiling surface 3 in a hanging state.

There are no particular limitations on the connecting member 4, and examples include a configuration that includes an upward socket portion into which the lower end of the shaft 2 fits, and a horizontal socket portion into which the end of the hanger pipe 5 fits, and that has a means for preventing each from coming loose, such as a screw fastening means.

In the hanging device 100 shown in FIG. 8, the connecting member 4 is provided only at the lower end of the shaft 2, but this is not limiting. That is, the connecting member may be provided, for example, midway along the shaft 2 to support the hanger pipe there, or a total of multiple connecting members may be provided at one or more midway points and at the lower end to support multiple hanger pipes. In this case, the connecting member provided midway and the connecting member provided at the lower end have different shapes, structures, etc., and are designed according to their functions.

The hanger pipe 5 is a straight pipe with a generally rectangular cross section and rounded top and bottom surfaces. An object to be hung, such as a flowerpot 6 in the example of Fig. 8, is hung from the hanger pipe 5 and used as a hanging device. The hanger pipe 5 is made of a material such as aluminum or resin.
The peripheral surface of the hanger pipe 5 may be treated with an anti-slip coating to prevent the object to be hung from slipping or falling off.

In the hanging device 100 shown in FIG. 8, the hanging pipe 5 is exemplified as a roughly rectangular cross-section which is highly aesthetically pleasing and practical, but the hanging pipe may be a straight pipe with a circular cross-section like a typical clothesline pole, or even a solid rod that is not tubular (e.g. a wooden rod) (i.e., the concept of "hanger pipe" in this invention includes any object that is faithful to the shape).

According to the hanging device 100 of the example in FIG. 8, when a lateral external force acts on the hanging object such as the flower pot 6, the hanger pipe 5, or the shaft 2, the shaft 2 can tilt diagonally. Therefore, the entire hanging device 100 bends diagonally relative to the mounting point on the ceiling surface 3, reducing the lateral load and suppressing its effects.

In addition, with the hanging device 100 shown in FIG. 8, when an external force exceeding the threshold load required to tilt the shaft 2 or the like is applied, the user feels a clicking sensation and is able to recognize that excessive or strong force has been applied to the shaft 2 or the like in the lateral direction.

Then, when the applied external force is released and the lateral load is removed, the shaft 2 returns to the hanging position, and the entire hanging device 100 also returns to a normal shape (a shape in which the entire device is not bent).
The user can also feel a clicking sensation when the shaft 2 returns to the position on the axis X in the drooping state. Furthermore, unless an external force exceeding a threshold load is applied, the drooping state of the shaft 2 is likely to be maintained when there is no lateral load.

The shaft mounting member and hanging device using the same of the present invention have been described above with reference to preferred embodiments, but the shaft mounting member and hanging device using the same of the present invention are not limited to the configurations of the above embodiments. For example, in the above embodiment, the shaft 2 is fixed to the mounting member 1 by pressing the circumferential surface of the shaft 2 with the male screw 125, but any conventionally known method may be used.

In addition, in the above embodiment, the "connection portion" of the present invention is configured by the hinge 13 and the hinge cover 15 so that the shaft 2 and the joint 12 can be tilted at any angle of 360° with point O as the center point, but the configuration of the connection portion is not limited to this.

For example, a connection section may be formed by a cylinder fixed to the base while being held horizontally below the bottom surface of the base, and a pipe inserted into the cylinder, with a joint connected to the periphery of the pipe and hanging down, and the pipe rotating around the cylinder to allow the joint to swing.

In this case, the axis common to the pipe and the cylinder serves as the fulcrum for the swing, and the pipe swings to describe a single circular arc around the fulcrum. That is, in this case, in a plan view (when viewed from above), the swing of the shaft etc. causes the bottom end of the shaft to describe a straight line. On the other hand, in a configuration in which the shaft 2 etc. can be tilted in any direction through 360° as in the above embodiment, the swing causes the bottom end of the shaft to describe a circular surface in a plan view.

In the present invention, the configuration of the connection part includes a wide range of configurations in which the figure drawn by the lower end of the shaft as it swings in a plan view can be anything between a circular surface as in the above embodiment and a straight line. Of course, the figure drawn by the lower end of the shaft as it swings in a plan view can be a middle ground between a circular surface and a straight line. Examples of the middle ground include a configuration that draws two or more intersecting straight lines, a circular surface with a partial sector missing, a triangle, a square, a star or other geometric surface, or any other geometric surface. Any of these configurations satisfies the "connection part" of the present invention, which allows the shaft and joint to swing.

Regardless of the direction and magnitude in which the shaft and joint can swing, the tip of the pivot tilts in response to the swing in the swingable direction. Because the tip of the pivot is above the fulcrum of the swing, the abutment position on the underside of the base tries to move due to the swing. This creates a force that tries to move the tip of the pivot out of its fitted state in the recess provided on the underside of the base. Therefore, when a lateral external force that exceeds the threshold load required for the shaft to tilt diagonally acts, the user is given a clicking sensation and the shaft can tilt diagonally.

On the other hand, when the external force that was acting is eliminated and the lateral load is removed, the shaft returns to the drooping position. The user can also feel a clicking sensation when the shaft returns to the drooping position. In addition, since the shaft will not tilt unless an external force exceeding a threshold load is applied from the side, the shaft is likely to maintain a drooping state when there is no lateral load.

In the above embodiment, the recess 114 provided on the underside of the base 11 is relatively large, and even if the shaft 2 is tilted by a lateral external force, the tip 142 of the pivot 14 does not completely deviate from the recess 114; however, the present invention is not limited to this. For example, the recess 114 may be sufficiently small compared to the tip 142, and the tip 142 of the pivot 14 may completely deviate from the recess 114 when the shaft 2 is tilted by a lateral external force.

In this case, the tip 142 of the pivot 14 that has deviated from the recess 114 comes into contact with the annular plane 113 around the recess 114. Even in this case, the shaft 2 returns to a hanging state due to the action of gravity that causes the shaft 2 and the hinge 13, etc., to return to a vertical state, and the user can also feel a clicking sensation when the tip 142 of the pivot 14 fits into the recess 114 as it returns. In addition, the action and effect of the tip 142 of the pivot 14 not coming out of the state where it is fitted into the recess 114 is the same as in the present embodiment, so that when there is no load from the lateral direction, the hanging state of the shaft 2 is easily maintained.

In addition, those skilled in the art may modify the shaft mounting member of the present invention, and the sling and hanging device using the same, as appropriate, in accordance with previously known knowledge. As long as such modifications still provide the configuration of the present invention, they are of course included in the scope of the present invention.
