The support column mounting device 1 according to this embodiment is used to attach the lower end side of the support column 11 of various articles provided with the support column 11 to the top plate 10 constituting furniture such as desks and tables, office equipment, and the like. It is something that can be done. Examples of various articles provided with the support columns 11 include a desk lamp, a desk light, and the like. In the illustrated example, the mounting device 1 is provided with a mounting portion 12a for a fixed telephone device on the upper portion, and a telephone stand formed by connecting the mounting portion 12a and the support column 11 with an arm portion 12b is mounted on the top plate 10. An example is shown.

The mounting device 1 includes a strut holding portion 2 configured to be able to hold the lower end portion of the strut 11, and a clamp portion 3 with respect to the top plate 10. The clamp portion 3 is located below the support column holding portion 2.

The column holding portion 2 includes a tubular main body 4 in which the upper end 4a of the cylinder is opened and the lower end 4b of the cylinder is closed, a male screw body 5, and a lock body 6.

In the illustrated example, the tubular main body 4 exhibits a cylindrical shape having a cross section orthogonal to the tubular axis (corresponding to the vertical axis x shown in FIG. 1 in the illustrated example) at each position extending in the vertical direction. ing. The inner diameter of the tubular main body 4 is substantially equal to the outer diameter of the support column 11 to be held. As a result, in this embodiment, in a state where the mounting device 1 is fixed to the top plate 10, the support column 11 to be held from the cylinder upper end 4a side of the cylindrical main body 4 constituting the support column holding portion 2 When the lower end side is inserted, the column of the telephone stand can be rotated around the cylindrical axis of the cylindrical main body 4, that is, the telephone stand can be swiveled around the vertical axis x. 11 can be held.

In the illustrated example, the male screw body 5 is configured to form a hexagon bolt. In the illustrated example, the male screw body 5 has substantially the same length as the total length of the tubular main body 4, and its head portion 5a is fixed to the center of the closed portion 4c of the cylindrical lower end 4b of the tubular main body 4. It is integrated with the tubular main body 4, and extends downward from the center of the closed portion 4c.

The lock body 6 is combined with the outside of the support column 2 and, in the illustrated example, the outside of the closed portion 4c of the tubular main body 4 in a state where the lock body 6 can move up and down and cannot rotate around the vertical axis x.

The lock body 6 is formed by forming a circumferential ridge portion 6b inside a short cylindrical ring portion 6a in which both ends of the cylinder are open. A plurality of protrusions 6d are formed on the protruding surface 6c of the circumferential ridge portion 6b parallel to the cylinder axis of the ring portion 6a with a gap between the protrusions 6d and the adjacent protrusions 6d in the direction around the cylinder axis. On the other hand, on the outside of the closed portion 4c of the tubular main body 4, a plurality of grooves 4d extending in the vertical direction for receiving the protrusions 6d of the lock body 6 are formed so as to match the number and position of the protrusions 6d. As shown in FIG. 9, the bottom of the groove 4d is formed with a protruding portion 4e that slightly reduces the depth of the groove 4d at a position in the middle of the vertical direction. The lock body 6 is positioned on the first portion 7 described later of the clamp portion 3 in a state where the protrusion 6d is housed in the groove 4d. As a result, the lock body 6 can move up and down within the range of the groove 4d, but is combined with the support column holding portion 2 in a non-rotatable state around the vertical axis x.

Further, the lock body 6 is formed with an engaging portion 6e that engages with the engaged portion 7a provided in the first portion 7 at a position where the lock body 6 is completely moved downward. In the illustrated example, the engaging portion 6e is formed on the lower surface portion 6i of the circumferential ridge portion 6b.

At the position where the lock body 6 is completely moved downward, the protrusion 6d is positioned below the protrusion 4e in the groove 4d. At this position (FIG. 2), the engaging portion 6e engages with the engaged portion 7a, grips the first portion 7, and attempts to rotate the support column holding portion 2 around the vertical axis x in the R1 direction in FIG. However, since the support column holding portion 2 and the first portion 7 are integrated via the lock body 6, the support column holding portion 2 cannot be rotated. When the lock body 6 is moved upward from the position where the lock body 6 is completely moved downward, the circumferential ridge portion 6b side of the lock body 6 is slightly elastically deformed, the protrusion 6d gets over the protrusion 4e, and the engagement portion is engaged. The engagement between the 6e and the engaged portion 7a is disengaged, and the protrusion 6d is positioned above the protrusion 4e in the groove 4d, and the disengaged state is maintained. There is. In this disengaged state, it is possible to grip the first portion 7 and rotate the support column holding portion 2 around the vertical axis x in the R1 direction in FIG.

In the illustrated example, the engaging portion 6e has a serrated shape in which convex portions and concave portions are alternately provided in the direction around the vertical axis x and the convex portions are the tooth portions 6f, and the engaged portion 7a is formed. Also has a serrated shape in which convex portions and concave portions are alternately provided in a direction rotating around the vertical axis x corresponding to the convex portions, and the convex portions are the tooth portions 7b. Further, each of the tooth portions 6f and 7b constituting these has a stop surface 6g and 7c substantially parallel to the vertical axis x on one side surface and an inclined relief surface 6h and 7d on the other side surface. The rotation operation of the support column holding portion 2 in the R1 direction is blocked by the stop surfaces 6g and 7c, but the rotation operation of the support column holding portion 2 in the R2 direction in the opposite direction is locked by the inclination of the relief surfaces 6h and 7d. It is allowed by moving the body 6 upward. When the support column holding portion 2 is rotated in the R2 direction, the second portion described later of the clamp portion 3 is moved upward. That is, the rotation operation of the support column holding portion 2 in the direction in which the top plate 10 is tightened by the first portion 7 of the clamp portion 3 and the second portion 8 described later is always allowed.

On the other hand, the clamp portion 3 enables the top plate 10 to be sandwiched between the first portion 7 having the lower portion abutting portion 7e with respect to the upper surface of the top plate 10 and the abutting portion 7e of the first portion 7. It has a sandwiching portion 8a and a second portion 8 which is combined with the first portion 7 in a vertically movable and non-rotatable state around the vertical axis x.

The second portion 8 is screwed so as to be moved up and down by the rotation operation of the holding portion 2 around the vertical axis x.

In a state where the edge portion of the top plate 10 is interposed between the contact portion 7e of the first portion 7 and the sandwiching portion 8a of the second portion 8, the contact portion 7e of the first portion 7 is pushed onto the upper surface of the top plate 10. For example, if you are right-handed while hitting, hold the first part 7 with your left hand. From this state, for example, if the support column 2 is right-handed, when the rotation operation is performed with the right hand, the second portion 8 is combined with the first portion 7 in a vertically movable state and in a non-rotatable state around the vertical axis x. Therefore, the second portion 8 can be moved upward to sandwich the edge portion of the top plate 10 between the contact portion 7e of the first portion 7 and the sandwiching portion 8a of the second portion 8. As a result, the mounting device 1 can be easily mounted on the top plate 10. When the mounting device 1 is removed from the top plate 10, the support column holding portion 2 is rotated in the opposite direction to the above while gripping the first portion 7 in the same manner as described above to move the second portion 8 downward.

In the illustrated example, the first portion 7 includes a tubular body portion 7f, a top portion 7k that closes the upper end of the body portion 7f, and a bottom plate 7o attached to the lower end of the body portion 7f.

A through hole 7m of the male screw body 5 is formed in the center of the top portion 7k. Further, on the outer surface of the top portion 7k, a circumferential rising portion 7n having a short cylindrical shape is formed. Then, the engaged portion 7a is formed at the protruding end portion of the peripheral rising portion 7n.

The body portion 7f has a curved side surface 7g formed substantially along an arc of a virtual circle centered on the vertical axis x and a flat side surface 7h parallel to a virtual vertical surface including the vertical axis x. And an intermediate side surface 7i formed so as to make the curved side surface 7g and the flat side surface 7h continuous.

On the upper surface of the bottom plate 7o, a fixing portion of the receiving metal fitting 7p that rotatably supports the lower end of the male screw body 5 is formed, and the male screw is passed through the through hole 7m of the top portion 7k into the body portion 7f. When the support column holding portion 2 is rotated as described above, the body 5 rotates in the body portion 7f, that is, in the first portion 7 of the clamp portion 3.

Further, the bottom plate 7o is in a form of closing the lower end of the body portion 7f with a gap 9 formed between the flat side surface 7h and the vertical portion 8e described later of the second portion 8. ..
