2. Description of the Related Art Conventionally, for example, a hanging device is known in which a hanger pipe represented by a clothesline is substantially horizontally supported with respect to a hanging shaft having one end attached to a mounting surface such as a ceiling. Also known is a sling that is attached to a mounting surface and has an annular sling ring portion at the tip of a shaft that hangs down, and that is used by hanging an object that can be hung, such as a hanger, on the sling ring portion. there is One end of the shaft in such a hanging device or sling is attached to the surface to be attached by some kind of attachment member.

At this time, if the shaft is firmly fixed to the mounting member that is fixedly mounted on the mounting target surface, when an external force is applied to the hanging shaft from the lateral direction, the ceiling surface to which it is fixed A load may be applied to the surface to be mounted or the mounting member, which may cause accelerated deterioration of these. In addition, since it is better for the user to avoid collision as much as possible, the user may be nervous to avoid the collision.

On the other hand, there is known a technique for swingably supporting a shaft with respect to a mounting member that is fixedly mounted on a surface to be mounted (see, for example, Patent Document 1). When the shaft ("hanging rod 5" in Patent Document 1) hangs down swingably from the mounting surface, the lower end of the shaft or the hanger pipe supported by the shaft is attached to the hanging object. When trying to hang an object (“dry hanger 11” in Patent Document 1), the shaft (or “hanger pipe”) sways and becomes unstable, making the hanging operation difficult. In addition, when some lateral force is applied to the shaft, the suspended object swings with the shaft (or further with the "hanger pipe") and hits the surrounding walls, windows, etc. I have concerns.

However, the "horizontal" or "horizontal plane" does not have to be exactly perpendicular to the direction of gravity, and the present invention can be realized not only in the category of approximately horizontal but also in a somewhat oblique plane. As long as it is tilted to a certain degree, the concept includes such a tilted surface.

A shaft mounting member (hereinafter simply referred to as "mounting member") 1 according to the present embodiment supports a shaft 2 in a suspended state on a ceiling surface 3, which is an example of a mounting surface. In the present invention, the mounting surface is not limited to the ceiling surface. Any horizontal surface facing downward is acceptable.

As shown in FIGS. 1 to 4, the mounting member 1 according to the present embodiment specifically includes a base 11 mounted on the ceiling surface 3 and a joint 12 supporting one end (upper end) of the shaft 2 on the lower side. , 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 shafts 141 and 143 and a curved tip 142, and the pivot 14 facing the base 11. and a biasing coil spring 16 .

The base 11 has a disk-shaped base 111 and a cylindrical portion 112 concentrically rising downward. The base 111 is provided with four screw holes 115 that are symmetrical about a point on the axis X and are equally spaced in the circumferential direction. 3 to fix and attach the base 11 to the ceiling surface 3.

An annular flat surface 113 is provided on the inner peripheral side of the cylindrical portion 112 on the lower surface (downward facing lower surface) of the base 111 , and a concave portion 114 is provided in the center of the annular flat surface 113 . On the outer peripheral side of the cylindrical portion 112 of the base 111 and on the inner peripheral side of the area where the four screw holes 115 are located, four bolt holes 116 are provided at points symmetrically and at equal intervals in the circumferential direction. ing.

The hinge 13 has a columnar portion 131 that projects upward in the axis X direction from the joint 12, and a point that is connected to the columnar portion 131 and a part of the outer peripheral surface of which overlaps the central axis (same as the axis X) of the columnar portion 131. and a curved projecting portion 132 having a spherical shape with O as the center point. The hinge 13 also has a hole portion 133 recessed downward from the upper end of the curved projection portion 132 in the X-axis direction, and a screw hole 134 provided at the lower end of the cylindrical portion 131 .

The hole portion 133 in the hinge 13 includes a large inner diameter portion 135 on the upper side in the direction of the axis X, a small inner diameter portion 136 below the large inner diameter portion 135 and having an inner diameter smaller than that of the large inner diameter portion 135 , and a large inner diameter portion 135 . and an inner diameter stepped portion 137 connecting with the small inner diameter portion 136 . The large inner diameter portion 135 and the small inner diameter portion 136 are cylindrical cavities having the axis X as the center axis, and extend from the upper end of the hinge 13 to a region below the center in the axis X direction. Further, the small inner diameter portion 136 continues below the large inner diameter portion 135 and has a shorter length in the axis X direction than the large inner diameter portion 135 .

The shaft portions 141 and 143 of the pivot 14 include a large outer diameter portion 143 on the upper side in the X-axis direction, a small outer diameter portion 141 on the lower side of the large outer diameter portion 143, a large outer diameter portion 143 and a small outer diameter portion. 141 and an outer diameter step portion 144 that connects with 141 . The large outer diameter portion 143 has an outer diameter that allows it to be inserted into the large inner diameter portion 135 of the hole portion 133 of the hinge 13 and to be movable in the X-axis direction. On the other hand, the small outer diameter portion 141 has an outer diameter that allows it to be inserted into the small inner diameter portion 136 of the hole portion 133 of the hinge 13 and to be movable in the X-axis direction.

A hole 133 in the hinge 13 accommodates the pivot 14 and the coil spring 16 . Specifically, the small outer diameter portion 141 of the shaft portion of the pivot 14 is fitted into the coil spring 16 and accommodated in the hole portion 133 in a compressed state. An upper end portion 161 of the coil spring 16 is in contact with the outer diameter stepped portion 144 , and the other end of the coil spring 16 is in contact with the inner diameter stepped portion 137 at a lower end portion 162 .

The hinge cover 15 includes a ring portion 153 having a circular opening 156, a cylindrical tubular portion 152 rising upward from the outer periphery of the ring portion 153, and an annular flange projecting outward from the upper end of the tubular portion 152. and a part 151 . The flange portion 151 is provided with four screw holes 154 which are symmetrical about a point on the axis X and are equally spaced in the circumferential direction. 116 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 peripheral surface of the curved projecting portion 132 and larger than the diameter of the cylindrical portion 131 . The hinge cover 15 has the cylindrical portion 131 fitted into the circular opening 156, and the curved projecting portion 132 is positioned above (one side) of the circular opening 156, and the cylindrical portion 131 is positioned below (the other side). The hinge 13 is held in a folded state.

The outer peripheral surface of the curved projecting portion 132 of the hinge 13 is in contact with the opening edge 156' of the circular opening 156, and can rub against the opening edge 156'. Therefore, the outer peripheral surface of the curved projection 132 of the hinge 13 rubs against the opening edge 156' of the circular opening 156, so that the center axis of the hinge 13 is shifted from the axis X with the point O as the central point. Therefore, it is possible to tilt, that is, to swing.

With the point O as the central point, there is a limit to the angle of the central axis of the hinge 13 that can be tilted from the axis X (θ° in FIG. 5 to be described later). An arbitrary angle of 360° is possible as a structural characteristic of combination with the curved projection 132 .

The inner diameter of the opening edge 156' of the circular opening 156 has a tapered shape that gradually increases in diameter from the lower end to the upper end. Therefore, the opening edge 156' is in contact with the outer peripheral surface of the curved projection 132, so that the hinge 13 (and the joint 12, shaft 2, etc. supported by this) can be firmly supported. ing.

As the inner surface shape of the opening edge 156' of the circular opening 156, a curved surface shape corresponding to the outer peripheral surface of the curved surface projecting portion 132 ("corresponding curved surface shape" means a curved surface shape that completely follows a curved surface shape that almost follows). ) is more preferable from the viewpoint of stably supporting the hinge 13 .

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

In the mounting member 1 according to the present embodiment, the hinge 13 and the hinge cover 15 constitute a "connecting portion" according to the present invention (hereinafter referred to as "connecting portions 13 and 15"). According to the connecting portions 13 and 15 composed of the hinge 13 and the hinge cover 15, the joint 13 and the joint 12 can swing about the point O located below the lower surface of the base 11 as a fulcrum. 12 and base 11 are connected.

The pivot 14 housed in the hole 133 of the hinge 13 has the same axial inclination as the joint 12 to which the hinge 13 is fixed and the shaft 2 attached to the joint 12 as well as the hinge 13 . Therefore, the axes of the shaft portions 141 and 143 of the pivot 14 are tilted following the rocking of the joint 12 and the like.

The coil spring 16 sandwiched between the outer diameter stepped portion 144 and the inner diameter stepped portion 137 is maintained in a compressed state. Therefore, the pivot 14 abuts on the lower surface of the base 11 with its tip portion 142 biased. A biasing force that biases the tip portion 142 of the pivot 14 toward the lower surface of the base 11 acts due to the elastic force of the compressed coil spring 16 trying to expand.

A concave portion 114 is provided at a portion of the lower surface of the base 11 with which the tip portion 142 abuts, and the tip portion 142 of the pivot 14 is fitted into the concave portion 114 . That is, the distal end portion 142 of the pivot 14 is fitted into the recess 114, and the structure below the hinge 13 (joint 12, shaft 2, etc.) is stably maintained in a suspended state.

The joint 12 is cylindrical and has one opening 122 facing downward and the other opening 123 facing upward. More specifically, the joint 12 includes an outer cylindrical portion 121 forming an outer peripheral surface, an inner cylindrical portion 128 formed inside the outer cylindrical portion 121 by folding back at its upper end, and a lower end of the outer cylindrical portion 121 in the axial X-ray direction. and a bottom portion 129 that closes the lower end of the inner cylindrical portion 128 that ends on this side.

The inner peripheral surface continuing from the opening 123 is the inner peripheral surface of the inner tubular portion 128 , and the inner peripheral surface continuing from the opening 122 is the inner peripheral surface of the outer tubular portion 121 . A cylindrical portion 131 is inserted through the opening 123 to fix the hinge 13, and one end (upper end) of the shaft 2 is inserted through the opening 122 to support it.

In particular, a slit is formed between the inner peripheral surface of the outer cylindrical portion 121 and the outer peripheral surface of the inner cylindrical portion 128 to form an insertion opening 122' into which the pipe of the shaft 2 is inserted. The upper end of the slit of the insertion port 122' is the folded portion of the outer cylindrical portion 121 and the inner cylindrical portion 128, and the upper end of the inserted shaft 2 abuts thereon, thus serving as a positioning means for the shaft 2. .

A screw hole 126 is formed around the axis X in the bottom portion 129 of the joint 12 . A screw 127 is passed through the screw hole 126 and screwed into the screw hole 134 to fix the hinge 13 to the upper side of the joint 12 . The hinge 13 and the joint 12 are fixed before the shaft 2 is fitted into the opening 122 of the joint 12 (inserted into the insertion opening 122').

The outer cylindrical portion 121 of the joint 12 is formed with a hole portion 124 having a female screw groove formed on the inner peripheral surface thereof. The hole portion 124 is provided in a cylindrical projecting portion 124' raised from the outer surface of the outer cylindrical portion 121 in order to secure the length of the female screw groove. The hole 124 is drilled toward the shaft 2 fitted into the opening 122 . A male screw 125 is screwed into the hole 124 and has a male screw groove that engages with a female screw groove formed in the hole 124 .

When the male screw 125 is screwed into the hole 124 while one end of the shaft 2 is inserted into the opening 122 (inserted into the insertion opening 122 ′) of the joint 12 , the tip of the male screw 125 is inserted into the outer cylindrical portion 121 . It protrudes from the inner peripheral surface and presses the peripheral surface of the shaft 2 . One end (upper end) of the shaft 2 is fixed to and supported by the joint 12 by the pressing force of the male screw 125 .

1 and 3 show a normal state in which the shaft 2 is attached to the attachment member 1 of this embodiment and supported in a suspended state. For example, when used as a sling or hanging device, which will be described later, a force pushing or pulling in the front-rear direction may be applied when suspending an object, and an external force in the lateral direction may act on the shaft 2 . The mounting member 1 of this embodiment can be tilted obliquely when a load is applied from the lateral direction to the shaft 2 that is supported in a suspended state, but the load from the lateral direction is in a no-load state. , the hanging state of the shaft 2 is easily maintained.

Hereinafter, the operation and effect of this embodiment, in which the shaft 2 can be tilted obliquely but the hanging state of the shaft 2 is easily maintained when no load is applied from the lateral direction, will be described with reference to FIGS. 5 will be used for explanation.
FIG. 5 is a longitudinal cross-sectional view showing a state in which an external force in the lateral direction acts on the shaft 2 attached to the shaft attachment member 1 according to the present embodiment (a load is applied from the lateral direction). (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, the shaft 2 is pushed leftward and tends to tilt obliquely, as shown in FIG. 5(a). The mounting member 1 to which the shaft 2 is fixed also tends to tilt in the same direction together with the shaft 2, but as described above, the outer peripheral surface of the curved surface projecting portion 132 rubs against the opening edge 156' of the circular opening 156. Thus, the central axis of the hinge 13 can be tilted from the axis X at an angle.

At this time, due to the elastic force of the compressed coil spring 16, an urging force is applied in a state in which the tip end portion 142 of the pivot 14 is fitted into the recessed portion 114, and the tip end portion 142 of the pivot 14 is fitted into the recessed portion 114. There is a threshold for the magnitude of the external force (load) required to get out of the state. When the external force applied from the right to the left exceeds the threshold and the tip 142 of the pivot 14 moves away from its original position to the right, the center axis of the hinge 13 is tilted from the axis X at an angle. and tilt. The external force applied to the shaft 2 in the right to left direction is attenuated by the strength of the external force required to exceed this threshold.

Therefore, when an external force acts from the right to the left, the axis of the shaft 2 in this embodiment is tilted from the axis X in the hanging state, as shown in FIG. 5(a). It can tilt diagonally up to the state of Xa. Therefore, the load from the lateral direction is reduced, and its influence can be suppressed.

Further, in order for the tip portion 142 of the pivot 14 to deviate from the state in which it is fitted in the concave portion 114, an external force exceeding the threshold value is applied. will give. Therefore, when the user receives the click feeling, he or she can recognize that excessive or strong lateral force has been applied.

On the other hand, when the applied external force is released and the load from the lateral direction becomes unloaded, the elastic force of the coil spring 16 causes the tip 142 of the pivot 14 to move away from its original position to the right. An urging force acts to urge the position in the concave portion 114 . In addition, gravity acts to return the shaft 2, the hinge 13, and the like to the vertical state. The shaft 2 returns to the position of the axis X in the hanging state due to the action of the urging force due to the elastic force of the coil spring 16 and the action of gravity that causes the shaft 2, the hinge 13, and the like to return to the vertical state.

When the shaft 2 returns to the position of the axis X in the hanging state, the user can feel a click when the tip 142 of the pivot 14 fits into the recess 114 . Further, unless an external force exceeding the threshold value is applied, the tip portion 142 of the pivot 14 does not deviate from the state in which it is fitted into the recess 114. Therefore, when no load is applied from the lateral direction, the shaft 2 is in a drooping state. is easily preserved.

On the other hand, when an external force acts from left to right, the shaft 2 can tilt in the opposite direction to the case shown in FIG. 5(a). Although the detailed action is omitted, in this case, as shown in FIG. , is tilted at an angle from the axis X.

Then, when the external force acting from left to right is released and the load from the lateral direction becomes unloaded, the urging force due to the elastic force of the coil spring 16 and the shaft 2 and hinge 13 The shaft 2 returns to the position of the axis X in the vertical state due to the action of gravity that causes the shaft 2 to return to the vertical state.

In addition, in the description with reference to FIG. 5 , for the sake of convenience, a case in which lateral external forces act from directions that are 180° different (opposite directions) to the left and right is illustrated and described, but the present invention is not limited to this. That is, in the mounting member 1 of this embodiment, which is configured such that the hinge 13 can be freely tilted at any angle with respect to the hinge cover 15 by the spherical curved projection 132 and the circular opening 156, the shaft Similarly, the axis of shaft 2 can tilt obliquely when 2 receives an external force from any lateral direction of 360°.

Therefore, even if an external force acts on the shaft 2 in the horizontal direction, such as when a person bumps into it, the axis of the shaft 2 tilts obliquely, and the action of the external force is alleviated. After the applied external force is released and the load from the lateral direction becomes unloaded, the action of the urging force due to the elastic force of the coil spring 16 and the shaft 2 and the hinge 13 try to return to the vertical state. The action of gravity causes the shaft 2 to return to its hanging state.

The angle formed by the axis X in the hanging state and the axis Xa in the inclined state, that is, the maximum value of the inclination angle θ of the axis of the shaft 2 (see FIGS. 5A and 5B) is the curved surface tension. The relationship between the size and shape of the protruding portion 132 and the circular opening 156, the distance between the curved protruding portion 132 and the upper end of the joint 12 (the state of interference between the two), and the relationship between the base 11 and the hinge cover 15 It is determined by various conditions such as the available space.

By increasing the maximum value of the inclination angle .theta. If an attempt is made to increase the maximum value of the inclination angle θ of the axis of the shaft 2, the size of the mounting member 1 tends to increase. The maximum value of the tilt angle θ of the axis of the shaft 2 has no preferred range or limitation, but is selected from a range of about 1° to 20°.

The strength of the click feeling when the distal end portion 142 of the pivot 14 is deviated from the recessed portion 114 or when it is inserted from the deviated state can be used to adjust the elastic force of the coil spring 16 or to adjust the distal end portion 142 of the pivot 14 . and the shape of the concave portion 114 can be adjusted.

The click feeling can be strengthened by using a material having a strong elastic force as the coil spring 16 or using it in a more compressed state. Conversely, the click feeling can be weakened by using a material having a weak elastic force as the coil spring 16 or by using it in a less compressed state.

Further, the tip portion 142 of the pivot 14 and the concave portion 114 are fitted without a gap in a normal state (when the shaft 2 is in a hanging state), and when the shaft 2 is deviated, a step must be crossed to prevent a click. can make you feel stronger. Further, by making the step large and steep, the click feeling can be made stronger. On the other hand, the click feeling can be weakened by loosening the fitting between the tip 142 of the pivot 14 and the recess 114 in the normal state, by making the difference in level at the time of deviation gentle, or by forming a slope without the difference in level. can do.

In the shaft attachment member 1 according to this embodiment, the shaft 2 is detachable (attachable and detachable). Therefore, the same mounting member 1 is prepared (preliminarily mounting the mounting member on the mounting target surface, preparing a single mounting member that does not include a shaft in the lineup of products to be sold, and furthermore, It includes all cases of preparing multiple types of sets of one mounting member and different types of shafts.) It is easy to combine or change with shafts of different types such as length and shape. is.

As shown in FIGS. 6 and 7, it has a mounting member 1 and a shaft 2 whose one end is supported by the mounting member 1, and the other end (lower end) of the shaft 2 is provided for hooking an object. It can be used as a hanging tool by providing the hanging ring part 7 which is attached.
The hanging ring portion 7 is composed of a cylindrical fixing portion 71 and an annular portion 72 fixed to the lower end thereof. The fixed portion 71 has an open top, into which the lower end of the shaft 2 is inserted and stopped at the closed lower end for positioning.

The fixing portion 71 has two holes 714 a and 714 b having female thread grooves formed on the inner peripheral surface, similar to the hole 124 in the outer cylindrical portion 121 of the joint 12 . The holes 714 a and 714 b are drilled toward the shaft 2 fitted into the fixing portion 71 . Male screws 715a and 715b having male thread grooves screwed into the female thread grooves formed in the hole portions 714a and 714b are screwed into the hole portions 714a and 714b, respectively.

In the vicinity of the lower end of the shaft 2, a constricted constricted portion 25 is formed over the entire circumference. ing. When the lower end of the shaft 2 fitted into the fixing portion 71 is positioned in contact with the closed lower end, the constricted portion 25 comes to a position facing the tip of the male screw 715a.

In this state, when the male screws 715a and 715b are screwed into the holes 714a and 714b, the tips of the male screws 715a and 715b protrude from the inner peripheral surface of the fixing portion 71 and press the peripheral surface of the shaft 2. As shown in FIG. The fixing portion 71 is fixed to the lower end of the shaft 2 by the pressing force of the male screws 715 a and 715 b , and the suspension ring portion 7 is provided on the shaft 2 .

At this time, the tip of the male screw 715a that is screwed into the hole 714a protrudes so as to fit into the constricted portion 25 of the shaft 2, presses the shaft 2, and the fixing portion 71 is firmly fixed so as not to move vertically. Fixed. On the other hand, the tip of the male screw 715b screwed into the hole 714b protrudes from the outer peripheral surface of the straight tube portion 21 of the shaft 2 to press and hold the shaft 2 down. That is, the entire suspension ring portion 7 is fixed to the shaft 2 by the male screws 715a and 715b while the vertical movement of the suspension ring portion 7 is restricted by the male screw 715a.

The hanger configured as described above is attached to the annular portion 72 of the hanger ring portion 7 provided on the shaft 2, for example, a hanger for clothes or laundry, or one end of a clothesline pole 8 as shown in FIG. etc. can be hung and used. When the clothes-drying pole 8 is hung and used, another hanging tool is prepared to form a pair, and both ends of the clothes-drying pole 8 are hung on the annular part 72 of the hanging ring part 7 to bridge the hanging parts. Just do it.

6 and 7, when an external force in the horizontal direction acts on the clothes or the clothesline 8, which are the objects to be hung, or the shaft 2, the shaft 2 tilts obliquely. is possible. Therefore, the entire hanger bends obliquely with respect to the mounting target surface such as the ceiling surface, thereby reducing the load from the lateral direction and suppressing the influence thereof.

6 and 7, the user receives a click feeling when an external force exceeding the threshold of the load required for tilting the shaft 2 or the like is applied. etc., it can be recognized that excessive or strong force was applied in the lateral direction.

Then, when the applied external force is released and the load from the lateral direction becomes no load, the shaft 2 returns to the hanging position. As a result, the entire sling also returns to its normal shape (the shape in which the entire sling is not bent).
When the shaft 2 returns to the position of the axis X in the hanging state, it is possible to give a click feeling to the user. In addition, since the shaft 2 does not tilt unless an external force exceeding the threshold value is applied from the lateral direction, the shaft 2 is easily maintained in a hanging state when no load is applied from the lateral direction.

6 and 7, the suspension ring portion 7 is provided only at the lower end of the shaft 2, but the suspension using the shaft mounting member of the present invention is limited to this. not. That is, the suspension ring portion may be provided at a total of two or more locations, i.e., the lower end of the shaft and one or more midpoints, or may be provided only at one or two or more midpoints. I do not care.

Furthermore, the mounting member 1 according to this embodiment can be used together with the shaft 2 as a structural member that supports the 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.

As shown in FIG. 8, the hanging device 100 includes a hanger pipe 5 used for hanging things, a pair of left and right mounting members 1 (two pieces) according to the present embodiment, and one end of each mounting member 1. and a pair (two) of connecting members 4 supporting the ends of the hanger pipes 5 at the lower ends of the respective shafts 2 . The hanger pipe 5 is supported at its left and right ends by the pair of connecting members 4 and held substantially horizontally.
A pair, that is, two pieces (books) of the mounting member 1, the shaft 2 and the connecting member 4 have the same configuration. Therefore, for the sake of convenience, one item will be described below.

In the mounting member 1, a base 11 is mounted on a ceiling surface 3, which is a surface to be mounted, with wood screws or the like, and one end of a shaft 2 is fitted into a joint 12 to support it. That is, the shaft 2 is attached to the ceiling surface 3 in a suspended state by the attachment member 1 according to this embodiment.

The connecting member 4 is not particularly limited. Means, for example, a configuration having a screwing means can be mentioned.

In addition, in the hanging device 100 of the example of FIG. 8, although the connection member 4 is provided only at the lower end of the shaft 2, it is not limited to this. That is, the connecting member may be provided, for example, in the middle of the shaft 2 to support the hanger pipe there, or a plurality of connecting members may be provided at one or more points in the middle and at the lower end, A plurality of hanger pipes may be supported. In that case, the connecting member provided in the middle and the connecting member provided at the lower end are different in shape, structure, etc., and correspond to their functions.

The hanger pipe 5 is a pipe-shaped straight pipe having a substantially rectangular cross section with rounded upper and lower surfaces. An object to be hung such as the flowerpot 6 in the example of FIG. 8 is hung on the hanger pipe 5 and used as a hanging device. The hanger pipe 5 is molded from a material such as aluminum or resin, for example.
The peripheral surface of the hanger pipe 5 may be provided with a non-slip treatment so that the hanging object does not easily slip or come off.

In the hanging device 100 in the example of FIG. 8, the hanger pipe 5 has a substantially rectangular cross section, which has high design and practicality. The hanger pipe may be a solid bar (for example, a wooden bar) that is not pipe-shaped (that is, in the present invention, the concept of "hanger pipe" is faithful to the concept of "hanger pipe". shall be included).

According to the hanging device 100 in the example of FIG. 8, when an external force in the lateral direction acts on the object to be hung such as the flowerpot 6, the hanger pipe 5, or the shaft 2, the shaft 2 may tilt obliquely. It is possible. Therefore, the hanging device 100 as a whole bends obliquely with respect to the mounting location on the ceiling surface 3, thereby reducing the load from the lateral direction and suppressing its influence.

Further, according to the hanging device 100 in the example of FIG. 8, when an external force exceeding the load threshold required for tilting the shaft 2 or the like is applied, the user receives a click feeling. On the other hand, it can be recognized that excessive or strong force was applied in the lateral direction.

Then, when the applied external force is released and the load from the lateral direction becomes no load, the shaft 2 returns to the hanging position. Therefore, the hanging device 100 as a whole also returns to its normal shape (the shape in which the whole is not bent).
When the shaft 2 returns to the position of the axis X in the hanging state, it is possible to give a click feeling to the user. In addition, unless an external force exceeding a threshold value is applied, the shaft 2 is likely to be kept in a hanging state when no load is applied from the lateral direction.

The preferred embodiments of the shaft mounting member and the hanging device using the same according to the present invention have been described above. It is not limited. For example, in the above-described embodiment, as a method of fixing the shaft 2 to the mounting member 1, an example of fixing the shaft 2 by pressing the peripheral surface of the shaft 2 with the male screw 125 is given. I don't mind.

In the above-described embodiment, the "connecting portion" referred to in the present invention is the hinge 13 and the hinge cover 15 that allow the shaft 2 and the joint 12 to be tilted at any angle of 360° with the point O as the central point. Although this is a possible configuration, the configuration of the connecting portion is not limited to this.

For example, the connecting portion is composed of a cylindrical body fixed to the base while being horizontally held below the lower surface of the base and a pipe into which the cylindrical body is inserted, and the joint is connected to the peripheral surface of the pipe. It is also possible to apply a configuration in which the joints and the like are allowed to swing when the pipe rotates around the cylindrical body and hangs downward.

In this case, the shaft common to the pipe and the cylindrical body serves as a fulcrum for swinging, and swings so as to draw a single arc about the fulcrum. That is, in this case, in plan view (viewed from above), the lower end of the shaft draws a straight line due to the swinging of the shaft and the like. On the other hand, in the configuration in which the shaft 2 and the like can be tilted in any direction by 360° as in the above embodiment, the lower end of the shaft can draw a circular surface due to the rocking movement in plan view.

In the present invention, the configuration of the connecting portion widely includes a configuration in which the figure drawn by the lower end of the shaft by swinging in plan view can draw a circular surface as in the above-described embodiment, or a configuration that draws a straight line. . Of course, in plan view, the figure drawn by the lower end of the shaft by swinging may be an intermediate configuration between a configuration that can draw a circular surface and a configuration that draws a straight line. The intermediate configuration includes a configuration that can draw two or more intersecting straight lines, a circular surface that lacks a part of a sector, a triangle, a square, or a surface with other figures such as a star, etc. A configuration that can draw a plane of a figure can be mentioned. Any of these constructions satisfies the "connecting portion" of the present invention in which the shaft and the joint can swing.

Even if the shaft and the joint can swing in any direction and to what extent, the tip of the pivot tilts following the swing in the swingable direction. Since the tip of the pivot is above the fulcrum of the swing, the contact position on the lower surface of the base tends to move due to the swing. Then, a force is exerted to deviate from the state in which the tip of the pivot is fitted into the recess provided on the lower surface of the base. Therefore, when an external force in the lateral direction exceeding the load threshold required for the shaft to tilt obliquely acts, the user can feel a click and the shaft can tilt obliquely.

On the other hand, when the applied external force is released and the load from the lateral direction becomes no load, the shaft returns to the hanging position. A click feeling can be given to the user even when the shaft returns to the suspended position. In addition, since the shaft does not tilt unless an external force exceeding the threshold value is applied from the lateral direction, the shaft is easily maintained in a hanging state when no load is applied from the lateral direction.

In the above-described embodiment, the recess 114 provided on the lower surface of the base 11 is relatively large, and even if the shaft 2 is tilted by an external force from the lateral direction, the tip 142 of the pivot 14 can be completely displaced from the recess 114. gives an example that does not deviate, but the present invention is not limited to this. For example, when the concave portion 114 is sufficiently small relative to the tip portion 142 and the shaft 2 is tilted by an external force from the lateral direction, the tip portion 142 of the pivot 14 is completely deviated from the concave portion 114. There may be.

In this case, the tip 142 of the pivot 14 deviating from the recess 114 comes into contact with the annular flat surface 113 around the recess 114 . Even in that case, the shaft 2 returns to the hanging state due to the action of gravity that tries to return the shaft 2 and the hinge 13 and the like to the vertical state. A click feeling can also be given to the user. In addition, as long as an external force exceeding the threshold is not applied, the front end portion 142 of the pivot 14 does not deviate from the state in which it is fitted into the recess 114, which is the same as in the case of this embodiment. is in a no-load state, the hanging state of the shaft 2 is likely to be maintained.

In addition, those skilled in the art can appropriately modify the shaft attachment member of the present invention, and the sling and hanging device using the same, according to conventionally known knowledge. As long as the configuration of the present invention is still provided even with such modification, it is, of course, included in the scope of the present invention.
