An adhesive pad 15 as an adhesive part that exhibits high adhesiveness to the top surface P1 of the top plate is attached to the outer peripheral part of the suction surface 11B so as to surround the recessed part 110. Therefore, when suctioning the suction cup part 11 to the top surface P1, a sealed space is defined between the top surface P1 and the recessed part 110, and the adhesive pad 15 is attached to the top surface all around the top surface P1. It makes surface contact with the upper surface P1 and adheres with a predetermined adhesive force. In this way, the suction cup portion 11 is suctioned and fixed to the top surface P1 by the suction force due to the negative pressure suction effect of the sealed space and the adhesive force of the adhesive pad 15.

A plate-shaped tongue piece 16 is formed on the outer peripheral end surface 11C of the suction cup part 11, and serves as a grip when the suction cup part 11 is removed from the top surface P1. As shown in FIGS. 5 and 6, in the center of the suction cup upper surface portion 11A, which is the surface opposite to the suction surface 11B of the suction cup portion 11, there is a substantially square column-shaped support shaft for connecting a core member 21, which will be described later. 17 is erected, and by moving the support shaft 17 up and down, the height position of the bottom surface of the recessed part 110 relative to the surface to be attracted changes up and down. The support shaft 17 is made of a harder resin material than the suction cup portion 11.

The adsorption force adjustment section 12 includes a core member 21 connected and fixed to the support shaft 17, a core receiving section 22 that supports the core member 21, and an inner cylinder section 23 serving as a guide section that holds the core member 21 in a vertically movable manner. , a spring member 24 that presses the suction cup part 11 downward from the suction cup top surface part 11A side, an operation dial 25 as an operation part for vertically changing the support position of the core member 21 by the core receiving part 22, and an operation dial. 25 rotatably supported.

Thereby, the posture of the suction cup part 11 is stabilized, and the suction cup part 11 can be easily and reliably attracted to the top surface P1.

The dial support portion 26 is formed in a generally annular raised shape at the tip of the leg portion 14 on the upper surface of the base portion 101, that is, at a position above the suction cup portion 11. The inner cylinder part 23 is formed into a substantially cylindrical shape with a smaller diameter than the inner peripheral wall 260 of the dial support part 26, is erected at the center inside the dial support part 26, and has a bottomed part between it and the support part inner peripheral wall 260. An annular groove portion 30 is defined.

The inner cylindrical portion 23 extends from the bottom surface 301 of the groove portion 30 to approximately the same height as the dial support portion 26, and has an upper edge at two diagonal locations on its peripheral wall. A notch 31 having a predetermined width is formed extending from the groove 30 to the vicinity of the bottom surface 301 of the groove 30.

As shown in FIGS. 5, 6, and 7, a substantially cylindrical core member 21 is inserted into the inner space of the inner cylinder portion 23. As shown in FIGS. Narrow plate-shaped engagement pieces 32 are formed at two diagonal locations on the upper end outer circumferential surface of the core member 21 , and are fitted into the notches 31 of the inner cylindrical portion 23 . Further, the engaging piece 32 extends to a position above the core receiving part 22 formed on the inner peripheral surface of the operation dial 25, and engages with the core receiving part 22 from above. Thereby, the core member 21 is prevented from rotating in the circumferential direction in the inner space of the inner cylinder part 23 and is held in a state where it can slide up and down within the range in which the notch 31 is formed. .

A spindle insertion hole 33 into which the spindle 17 of the suction cup portion 11 is inserted is provided at the lower end of the core member 21, and the core member 21 is inserted into the inner space of the inner cylinder portion 23. At the same time, the support shaft 17 of the suction cup portion 11 is inserted into the support shaft insertion hole 33, and is fixed to the support shaft 17 with screws in this state. As a result, the suction cup portion 11 is held together with the core member 21 on the lower surface portion of the base portion 101 (bottom surface portion 10B of the pedestal main body 10) in a state in which the suction cup portion 11 is prevented from coming off.

The operation dial 25 is formed into a generally annular shape when viewed from above and has an outer diameter that is approximately the same as that of the suction cup portion 11, and has a lower surface formed in a concave shape that approximately matches the raised shape of the upper surface of the dial support portion 26. The dial supporting portion 26 is provided at a position above the portion 11 so as to be overlapped from above.

The inner circumferential wall 250 of the operation dial 25 is formed to protrude downward from the center of the lower surface of the operation dial 25, and is fitted into the groove 30 with play along the inner circumferential surface of the support inner circumferential wall 260. The lower end portion 251 of the dial inner circumferential wall 250 is in contact with the bottom surface portion 301 of the groove portion 30 . Thereby, the operation dial 25 is rotatably supported with respect to the dial support part 26 along the groove part 30 provided on the inner peripheral side thereof.

The core receiving portion 22 is formed to protrude along the inner circumferential surface of the dial inner circumferential wall 250 with a substantially constant width in an arc shape when viewed from above. The core receiving portions 22 extend at two diagonal locations on the inner circumferential surface of the dial inner circumferential wall 250 over a range of approximately 90 degrees around the rotation axis of the operation dial 25 .

As shown in FIG. 8, the engaged portion 220 configured on the upper surface of the core receiving portion 22 is low at one end 22A side (clockwise starting end side when viewed from above) and low at the other end 22B side (clockwise when viewed from above). The terminal side) is sloped so that it is higher. Therefore, when the operation dial 25 is rotated in a predetermined unlocking direction (clockwise) and the core receiving part 22 moves toward the other end 22B with respect to the engaging piece 32, the supporting position of the engaging piece 32 is changed to the engaged part. 220 to move the core member 21 downward (see FIG. 8(a)). On the other hand, when the operation dial 25 is rotated in a predetermined locking direction (counterclockwise) and the core receiving part 22 moves toward the end 22A side with respect to the engaging piece 32, the supporting position of the engaging piece 32 is changed to the engaged part 220. , and move the core member 21 upward (see FIG. 8(c)). In this way, the core member 21 is configured to be movable up and down in accordance with the rotation operation of the operation dial 25.

As shown in FIGS. 6, 7, and 8, one end 22A side and the other end 22B side of the core receiving portion 22 on the inner peripheral surface of the dial inner peripheral wall 250 are engaged when the operation dial 25 is rotated. Rotation stopper ribs 34A and 34B are formed that abut against the piece 32 and limit rotation of the operation dial 25 beyond a certain level.

A starting end rib 34A serving as a rotation stopper rib on the one end 22A side of the core receiving portion 22 is connected to the one end 22A. A termination rib 34B serving as a rotation stopper rib on the other end 22B side of the core receiving portion 22 is formed with a predetermined gap 35 between it and the other end 22B.

A downwardly convex fitting protrusion 320 is formed on the lower surface portion 32B of the engaging piece 32 that engages on the engaged portion 220. Therefore, when the operation dial 25 is rotated in the locking direction to the position where the engaging piece 32 abuts the end rib 34B, the fitting protrusion 320 passes over the one end 22A of the core receiving part 22 and fits into the gap 35. As a result, the operation dial 25 is held in a locked state, and the core member 21 is held at a high position within the inner cylinder portion 23. That is, the support shaft 17 of the suction cup portion 11 is held in an upwardly pulled state. As a result, the internal pressure of the closed space defined between the suction surface 11B of the suction cup portion 11 and the top surface P1 decreases, and the suction force becomes larger.

If it is not possible to clamp to the side edges of the top plate P due to the arrangement environment, even if the top plate P has no side edges, the arm portion 6 can be stably fixed and held in an upright state. Furthermore, the possibility of causing scratches, deformation, damage, etc. on the top surface P1 is much lower than with a clamp.

Moreover, according to the pedestal 1 of the embodiment, by rotating the operation dial 25 to the lock position, the support shaft 17 of the suction cup part 11 is held in an upwardly pulled state, and the suction force of the suction cup part 11 is increased. Since it is larger, the pedestal main body 10 is more firmly fixed to the top plate upper surface P1. Thereby, the arm portion 6 can be more stably held in an upright state, and the installation stability of the telephone stand S is significantly improved.

Further, according to the pedestal 1 of the embodiment, the suction cup portions 11 are arranged at predetermined angular intervals in at least three different directions on the outer peripheral side of the base end of the fixed column 13, so that the pedestal main body 10 is Since the arm portion 6 is more stably fixed to the object, the arm portion 6 can be stably held in an upright state. Therefore, the installation stability of the telephone stand S is further improved.

Therefore, the installation stability of the telephone stand S is further improved.

Moreover, by providing the adhesive pad 15 in an annular shape so as to surround the recessed part 110 of the suction surface 11B, the airtightness of the airtight space defined between the top surface P1 and the recessed part 110 is improved. Since the height is higher, the pedestal main body 10 can be more firmly fixed to the top plate upper surface P1. Therefore, the installation stability of the telephone stand S is further improved.

In addition, in the pedestal 1 of the embodiment, when the operation dial 25 is rotated to a predetermined lock position, the support shaft 20 of the suction cup portion 11 is pulled toward the side opposite to the suction surface 11B, and while the suction force increases, the operation When the dial 25 is returned to the unlocked position, the tensile state of the suction cup portion 11 is released and the suction force is reduced. In this way, by rotating the operation dial 25, the suction force of the suction cup portion 11 can be easily changed, so that the pedestal main body 10 can be easily fixed to or removed from the top surface P1. becomes. Therefore, installation does not take much time.

Moreover, when the operation dial 25 is rotated to the lock position as described above, the fitting protrusion 320 of the engaging piece 32 is fitted into the gap 35 between the core receiving part 22 and the terminal end rib 34B. The click sound generated when the fitting protrusion 320 is fitted into the gap 35 and the vibration transmitted to the hand can clearly notify the user that the suction cup part 11 has been properly suctioned and fixed to the top surface P1. Therefore, a good feeling of use can be obtained.

Further, according to the pedestal 1 of the embodiment, the tongue piece 16 is provided on the outer peripheral end surface 11C of the suction cup part 11, and when the suction cup part 11 is removed from the top plate upper surface P1, the tongue piece 16 is pinched and the suction surface 11B If a part of the pedestal is peeled off from the top surface P1, the sealing state of the gap between the suction surface 11B and the top surface P1 is released, so that the pedestal main body 10 can be more easily removed from the top surface P1. .
