(Example)
Hereinafter, an embodiment which is a specific example of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic view showing an appearance of a hanging device 1 according to the present embodiment.

  The hanging device 1 includes a support rod 11 that is a full screw, a frame body 12 that has screw holes and is screwed to the support rod 11, and a suspended object 13 that is connected to the frame body 12. .

  The support rod 11 is a cylindrical rod-shaped body made of steel, for example. The length in the longitudinal direction of the support bar 11 is arbitrary because it varies depending on the intended use, but in this embodiment, it is 1 meter, for example. The support rod 11 is provided with a screw thread spirally in a clockwise direction when viewed from below in FIG. The diameter of the cross section obtained by cutting the support bar 11 along a plane perpendicular to the longitudinal direction is, for example, 3/8 inch.

  As will be described later, when a screw thread is provided in a clockwise direction when viewed from below (right screw), in order to screw the support bar 11 into the lower surface of the ceiling of the building, the support bar 11 is moved in the longitudinal direction of the support bar 11. It is necessary to rotate it clockwise while pressing from the bottom to the top around the axis.

  The frame body 12 has a hexagonal female screw 121 (the above-described screw hole) arranged in the upper part in a state of being horizontally arranged, and a frame portion 122 provided so as to be connected to the lower part of the female screw 121. The female screw 121 and the frame portion 122 are both made of steel, for example.

  The frame portion 122 has, for example, a shape in which an elongated plate-like member is bent at a predetermined portion in the longitudinal direction. Moreover, the width | variety of the direction perpendicular | vertical to the longitudinal direction in the said plate-shaped member is 2.5 centimeters, for example.

  More specifically, the frame portion 122 is welded to the lower portion of the female screw 121 and extends a predetermined length on both outer sides in the horizontal direction when viewed from the female screw 121, and then is set directly below so as to be bent vertically thereafter. And then bend inward at a predetermined length so that it bends inward at 60 degrees each, and bend at 120 degrees each when the frame portions 122 that extend from both sides are combined. A predetermined length is stretched directly below.

  In the portion of the frame portion 122 that extends from the both sides and is bent at a predetermined length so as to be bent at 120 degrees, a hole is provided so as to penetrate both plate-like members vertically. In a state where the suspended object 13 is arranged so that a hole of a predetermined part of the suspended object 13 communicates with the holes of the two plate-like members, bolts 14 are inserted into the holes communicated with each other. The nut 15 is tightened. As a result, the suspended object 13 is fixed below the frame body 12.

  The suspended object 13 is a steel annular body for supporting cables such as piping or power distribution. The ring has a diameter of, for example, 15 centimeters. Further, the width of the portion constituting the frame of the annular body is, for example, 2.5 centimeters.

  In use, the support bar 11 is screwed into the female screw 121. That is, the screw thread of the support rod 11 is screwed with the thread valley of the female screw 121. Then, along with the rotation about the axis about the longitudinal direction of the support rod 11 with respect to the female screw 121, one end surface which is the tip portion of the support rod 11 is the inner side surface of the wall portion of the frame body 12 (the frame constituting the frame portion 122). Move so that it touches or is close to the inner side. Note that the thread valley of the female screw 121 is cut slightly deeper than the normal thread valley with respect to the thread depth of the support bar 11 so that the frictional force between the support rod 11 and the female screw 121 is reduced. It has been.

  As shown in FIG. 1, when the support bar 11 is screwed with the frame 12, the end of the support bar 11 on the frame 12 side is omnidirectional on one plane including the longitudinal direction of the support bar 11. The shape is surrounded by the frame portion 122. On the other hand, the support bar 11 is not surrounded by the frame portion 122 in the vertical direction of the one plane, and the operator can visually recognize the support bar 11 from the opening of the frame body 12.

  In addition, the inner surface of the wall portion of the frame 12 that faces the end face of the support rod 11 that is screwed into the frame 12 forms two planes that intersect at an angle of 120 degrees. As will be described later, this serves to make the engagement more reliable when the hanging device 1 is set on the mounting device 2.

  Hereinafter, the attachment device 2 for attaching the hanging device 1 to the lower surface of the ceiling of the building will be described.

  FIG. 2 is a schematic diagram illustrating an appearance of the mounting tool 2 according to the present embodiment.

  The mounting tool 2 includes an operating rod 21, a plate-like body 22 arranged on a plane along the longitudinal direction of the operating rod 21, a first projecting portion 23, and two second projecting portions 24. Prepare.

  The operation bar 21 is, for example, an elongated rod-shaped body made of steel. The operating rod 21 has a cylindrical shape, and the diameter of a cross section obtained by cutting the operating rod 21 along a plane perpendicular to the longitudinal direction is, for example, 4.5 centimeters. The length of the operation bar 21 in the longitudinal direction is arbitrary depending on the intended use, but is 2.5 meters in the present embodiment, for example.

  The plate-like body 22 is made of steel, for example. The plate-like body 22 is an elongated plate-like body having a length of 25 centimeters, a width of 5 centimeters, and a thickness of 0.5 centimeter, and a portion of 5 centimeters from one end thereof is bent perpendicularly to the longitudinal direction. It has a different shape.

  As shown in FIG. 2, the plate-like body 22 is attached to an end portion on a side different from the side held by the operator of the operation rod 21 by, for example, welding in the bent portion. .

  As a result, the plate-like body 22 further extends from one end portion of the operation rod 21, and the length in the longitudinal direction of the attachment device 2 including the operation rod 21 and the plate-like body 22 is, for example, 2. 7 meters.

  The first protrusion 23 is made of steel, for example. The first protrusion 23 is a rod-like body having a length in the longitudinal direction of, for example, 4 centimeters. The cross section obtained by cutting the first protrusion 23 along a plane perpendicular to the longitudinal direction is a regular hexagon.

  The first protrusion 23 protrudes perpendicularly to the plate-like body 22 from the center position in the left-right direction when the direction perpendicular to the longitudinal direction of the operation rod 21 is the left-right direction on the plane including the plate-like body 22. doing.

  The second protrusion 24 is made of steel, for example. The 2nd projection part 24 is a plate-shaped member whose length of the longitudinal direction is 4 centimeters, for example.

  The second projecting portion 24 is formed from two mutually symmetrical positions with the center line in the left-right direction of the edge portion on the side different from the operation rod 21 side of the plate-like body 22 as the first projecting portion 23. Projecting in the same direction. Moreover, these two 2nd protrusion parts 24 have the space | interval which can insert the support rod 11 vertically between them.

  The length between the second protrusion 24 and the first protrusion 23 is arbitrary because it varies depending on the intended use, but is 6 centimeters in this embodiment.

  An example of how to use the hanging device 1 and the mounting device 2 having the above-described configuration will be described below with reference to the drawings.

  FIG. 3 is a schematic view showing an external appearance of the hanging device 1 set on the mounting device 2.

  First, the operator inserts the first protrusion 23 into the frame body 12 so as to penetrate the above-described opening of the frame body 12. At the same time, the worker inserts the support bar 11 between the two second protrusions 24. In this state, when the worker rotates the support bar 11 in a predetermined direction (clockwise when viewed from above) around the axis having the longitudinal direction as an axis, the support bar 11 is relative to the frame body 12 along with the rotation. The first protrusion 23 is sandwiched between the lower end surface of the support bar 11 and the inner surface of the wall of the frame 12. Thereby, the setting of the hanging device 1 with respect to the mounting device 2 is completed.

  By the way, an insert nut into which an end of the support bar 11 opposite to the side screwed into the frame body 12 is to be inserted is attached to the lower surface of the ceiling of the building. The operator lifts the attachment device 2 with the suspension device 1 set as described above, and presses the tip of the support rod 11 of the suspension device 1 so as to be inserted into the insert nut on the lower surface of the ceiling.

  In this state, when the operator rotates the operating rod 21 in a predetermined direction (clockwise when viewed from below), the plate-like body 22 and the first protrusion 23 rotate the frame body 12 in the same direction by the force. Let Accordingly, the support rod 11 screwed into the frame 12 at the lower end and fixed in position to the first protrusion 23 is also rotated in the same direction. As a result, the upper end of the support bar 11 is screwed into the insert nut.

  When the operator rotates the operation rod 21 as described above and firmly screws the support rod 11 into the insert nut, the support rod 11 is rotated in the direction opposite to the predetermined direction (counterclockwise when viewed from below). Rotate. With this force, the plate-like body 22 and the first protrusion 23 rotate the frame body 12 in the same direction (counterclockwise when viewed from below).

  At that time, the screwing into the insert nut at the upper end of the support bar 11 is hard, and the screwing into the female screw 121 at the lower end of the support bar 11 is looser than that. Therefore, the support bar 11 is not rotated while keeping the state fixed to the insert nut, and only the frame 12 is rotated. As a result, the frame 12 moves downward while rotating counterclockwise with respect to the support bar 11, and the first protrusion 23 sandwiched between the support bar 11 and the frame 12 is provided. Freed from the pinching.

  Since the first protrusion 23 is a hexagonal column as described above, and the lower end surface of the support bar 11 is in contact with the first protrusion 23 by a line, the support bar 11 and the first protrusion 23 are in contact with each other. Is not so large as to inhibit the rotation of the frame 12 relative to the support rod 11.

  By the way, when the operator rotates the operation rod 21 counterclockwise as viewed from below, the operator rotates the operation rod 21 too much and the lower end portion of the support rod 11 and the frame portion 122 are unscrewed, and the frame body 12 becomes the support rod. It is necessary to be careful not to drop off 11.

  As described above, when the first protrusion 23 is released from the clamping between the support bar 11 and the frame body 12, the connection between the attachment device 2 and the hanging device 1 is lost. Therefore, the operator operates the operation rod 21 and removes the plate-like body 22 of the attachment device 2 so as to peel it sideways from the suspension device 1. This completes the attaching operation of the hanging device 1 to the lower surface of the ceiling.

  In the present embodiment, the first protrusion 23 sandwiched between the lower end surface of the support bar 11 and the inner wall surface of the frame 12 is in contact with the wall inner wall surface. . This is because the inner side surfaces of the wall portions on both sides intersect with each other at 120 degrees, and since the first protrusions 23 are regular hexagonal columns, the angles of the six corners in the cross section are also 120 degrees. As described above, the first protrusion 23 and the inner surface of the wall portion of the frame body 12 are in contact with each other by two surfaces, so that they are not displaced from each other. It is preferable that the portion 23 does not come off from the inner side surface of the wall portion.

(Modification)
The embodiments described above can be variously modified within the scope of the technical idea of the present invention.

  For example, the numerical values indicating the shape, size, number, and the like of each element in the above-described embodiments are merely examples, and other numerical values may be adopted if there is no particular problem. For example, the length between the second protrusion 24 and the first protrusion 23 is 6 centimeters, but the present invention is not limited to this and may be shorter than 6 centimeters. It may be longer.

  However, if the length between the second protrusion 24 and the first protrusion 23 is increased to the same length as the support rod 11 (for example, 1 meter), the second protrusion 24 and Care should be taken because the support bar 11 interferes and hinders the screwing of the support bar 11 to the lower part of the ceiling of the building. As described above, it is necessary to change the size of each element according to the present embodiment to a desired size as appropriate according to the intended use.

  Further, the material of each element in the above-described embodiment is not limited to the above-described material as long as there is no particular problem, and another material may be adopted. For example, the support rod 11 and the like are made of steel, but may be made of other metals such as stainless steel and aluminum, or plastic if the sufficient strength can be secured.

  Moreover, although the support rod 11 shall be provided with the screw thread spirally clockwise on the outer surface in the whole area | region of the longitudinal direction, this invention is not limited to this. For example, the support rod 11 is long on the outer surface (for example, a portion screwed with the frame portion 122) in a region having a predetermined length in the longitudinal direction from one tip and from the other tip different from the one tip. It suffices if a screw thread is provided spirally in the same direction on each of the outer surfaces (for example, a portion screwed with the insert nut) in a region having a predetermined length in the direction. However, it is necessary to be careful because an area where the spiral thread is provided (length in the longitudinal direction) is too small.

  In addition, the first protrusion 23 has a hexagonal cross-sectional shape, but the present invention is not limited to this, and any other shape may be adopted as long as there is no particular problem. However, it is desirable from the viewpoint of force transmission and stability that the first protrusion 23 has a shape that makes contact with the inner side surface of the wall. Otherwise, when the user rotates the operation rod 11, the first protrusion 23 may be detached from the inner side surface of the wall, that is, may be displaced.

  In addition, the first protrusion 23 is in contact with the lower end surface of the support bar 11 by a line, but by devising the shape of the first protrusion 23 or the support bar 11, both You may employ | adopt the structure which touches by a point. For example, by making the upper surface of the first projecting portion 23 into a spherical shape, contact by both points becomes possible. Furthermore, if there is no particular problem, the lower end face of the first protrusion 23 and the support bar 11 may have any shape. However, when a shape in which the first projecting portion 23 and the lower end surface of the support rod 11 are in contact with each other is adopted, the frictional force with respect to the relative movement between the two becomes large. It is desirable to perform a separate treatment such as applying lubricating oil to the contact surfaces.

  In addition, the suspended object 13 is an annular body for supporting cables such as piping or power distribution, but the present invention is not limited to this. For example, the suspended object 13 may be an instrument having a shape other than an annular body such as a hook shape (hook shape), or may be an object that is not intended to suspend other objects such as a light bulb. .

  Further, the angle at which the inner side surfaces of the right and left walls intersect is 120 degrees. However, the present invention is not limited to this, and any other angle may be adopted as long as there is no particular problem. However, it is desirable that the angle at which the wall inner surface intersects with the angle formed by the side surface of the first protrusion 23 so that the first protrusion 23 contacts the wall inner surface.

  Further, the first protrusion 23 may be detachable from the plate-like body 22. The shape of the inner side surface of the lower wall of the frame 12 may vary depending on the hanging device. Therefore, the first protrusion 23 having a shape corresponding to each of the plurality of shapes is prepared, and the first protrusion 23 corresponding to the suspension device to be attached is attached to the plate-like body 22. It becomes possible to deal with various hanging devices having different shapes of the body 12 with one mounting device.

  Various known methods can be adopted as a method for making the protrusion 23 detachable from the plate-like body 22. For example, a screw hole is provided in the protrusion 23, a through hole is provided in the plate-like body 22, a bolt is inserted into the through-hole of the plate-like body 22 from the back side of the plate-like body 22, and further, A method of inserting the bolt and screwing it, a method of attaching a screw to the protruding portion 23 side by welding or the like, and screwing a screw portion of the protruding portion 23 into a screw hole provided on the plate-like body 22 side can be considered.

  Since the hanging device and the mounting device of the present invention are useful at the construction site or the like, many of them can be manufactured and sold. Therefore, it can be used in service industries such as so-called manufacturing and retailing.
