As shown in FIG. 5, this mounting device has a center hole (102) provided in an upper piece (101) a of a supporting member (101) having a U-shaped vertical cross section, and the upper surface of the upper piece (101) a. , The threaded hole (103) at the center, and the small-diameter portion on the lower surface has the central hole (10).
Fix the screwing piece (104) fitted to 2), and fix this screwing piece (10
The lower end of a long fixed column (105) which stands upright on the upper piece (101) a of the support member (101) is fitted around the outer periphery of 4) and fixed thereto, and Support members (101)
The pressing member (1 that holds the top plate A between the lower piece (101) b and
06) is an operating member (109) having a long screw shaft (107) which is screwed into the screw hole (103) of the screwing piece (104) and has a grip portion (108) on the outer peripheral portion. The operation member (109) is provided with a pressure contact plate (110) connected to the lower surface of the operation member (109) so as to be horizontally rotatable at its center position, and the top plate A is used as a lower piece (101) of the support member (101). The operating member (109) is rotated in a state of being interposed between b and the pressure contact plate (110), and the pressure contact plate (110) is rotated.
Lower to the lower piece (101) b, and the top plate A is attached to the support member (1
The lower part (01) b of 01) is sandwiched between the lower plate (101) b and the pressure contact plate (110), and the fixed column (105) is erected on the side of the top plate A. The mounting member (11
1) Through the rotating table (11)
The telephone support (114) consisting of 3) is provided with the rotating column (11).
3) is rotatably fitted, and in the case of a lighting fixture, the lighting fixture is mounted on the upper end of the fixed column (105).

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention According to the above-mentioned configuration, a long fixed pillar (105) is erected on the upper surface of the upper piece (101) a of the support member (101), and the upper piece (101) is provided. ) A below the operating member (1
09) exists, when the mounting device is mounted on the top plate A, the operating member (109) is sufficiently lifted to the upper piece (101) a side of the supporting member (101) and the lower piece (101). With a large gap formed between b and the lower surface of the operation member (109),
While slightly inclining the fixed column (105) in the forward direction, the support member (101) is provided on the top plate A and the wall surface B or the space p between the end faces of the top plates of the desks as shown by the phantom line in FIG. After the intervention, the fixed column (105) is raised and the support member (10
1) The edge of the top plate A is interposed between the lower piece (101) b and the lower surface of the operating member (109), and the grip (108) is rotated to lower the lower surface (101) b and the lower piece (101). ) B, since the top plate A is sandwiched between the top plate A and the fixed column (105), the top plate A and the wall surface B or the top plates of the desks can be mutually attached when the mounting device is attached. Since the supporting member (101) is interposed between them, a large amount of wasted space is required, and the fixed column (105) is also required.
Since the mounting operation is performed with the rotating column (113) provided, the mounting operation is also inconvenient. In addition, since it is necessary to raise the operating member (109) sufficiently at the time of mounting so as to allow a space for easily inserting the top plate A between the operating member (109) and the lower piece (101) b,
The height dimension of the support member becomes large, and accordingly, the screw shaft (107) also becomes long. Therefore, when the support member (101) is attached to the top plate A, the operating member (109) is largely lowered. Since the non-threaded length of the screw shaft (107) is also increased, there is a disadvantage that the mechanical strength of the horizontal bending force applied to the fixed column (105) is weakened.

In order to solve the above-mentioned problems, the present application has an upper piece and a lower piece that face each other in the vertical direction, and has a locking groove that is open at the edge of the upper piece. A support member having, a column member having a shaft portion which penetrates a screw hole at the center and has a shaft portion engageable with the locking groove at the lower end, and a screw shaft which is screwed into the screw hole of the shaft portion are provided upright. A support device having a grip part on the outer peripheral part and an operating member for sandwiching a fixing member such as a top plate between the grip part and the lower piece of the supporting member. In particular, in order to obtain the engagement strength between the upper piece of the support member and the shaft portion, the shaft portion is provided between the upper collar piece and the lower collar piece and engages with the locking groove. The supporting member is preferably formed by bending the supporting member in a U-shape in a longitudinal section and inclining a lower bent portion thereof. It is a thing. Further, the operation member has a long screw shaft that is screwed into the screw hole of the shaft portion at the center thereof and has a cylindrical grip portion on the outer peripheral portion thereof, and the press contact plate can be rotated on the lower surface thereof. When attached, the operation member can be easily rotated.

However, when the mounting device for the support of the present application is attached to a fixing member such as a top plate, for example, the support member separated from the supporting member including the operation member is tilted largely in the front direction, and the wall surface and the fixing member are separated from each other. Then, the lower piece of the supporting member is brought into contact with the lower surface of the top plate to erect the supporting member, and in this state, the shaft portion provided with the operating member is engaged with the engaging groove of the upper piece of the supporting member. Then, the operation member is rotated with the fixing member, for example, the top plate interposed between the lower piece of the support member and the operation member, and the top plate is clamped by the operation member and the lower piece of the support member. Then, it is erected on the edge of the top plate.
