DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. FIG. 1 is a cross-sectional top view showing a suction-preparation state of a suction cup-equipped hook according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of an essential portion showing the initial state of suction, and FIG. FIG. 3 is a cross-sectional view similar to FIG. 2, showing a state where body pressure is increased and the body is swollen. The inverted bowl-shaped suction cup 1 is formed of a soft elastic material such as soft rubber or soft vinyl chloride resin, and a head portion 21 of a bolt 2 made of a material such as metal or hard resin is formed in the center thereof.
Is buried and fixed. The pressing bowl 3 is formed of a hard material such as a thin metal plate, phenol, or urea resin, and the bolt 2 is loosely inserted into the center hole of the pressing bowl 3 and is mounted concentrically on a suction cup as shown in the drawing. The object hanging device main body 4 is formed of a hard material such as methacrylic resin, and a sliding hole 41 is formed in the center of the hanging device body 4 concentrically with the metal bolt 2. And the hanging body 4
Are concentrically stacked on the pressing bowl body 3. The object hanging device main body 4 has an inverted bowl shape, and the circular diameter of the bowl edge portion 42 is larger than the diameter of the circular bowl edge portion 31 of the pressing bowl body 3 but smaller than the diameter of the suction cup. An object to be suspended, such as a shower fountain, is provided with a hanging support portion 43 for hooking and supporting an object to be suspended, and a groove for hooking a string or the like is provided around the object hanging body. Sometimes. The tightening body 5 which is placed concentrically on the hanging body 4 is made of metal,
It is made of methacrylic or other hard material, and the lower sliding part 51 has a cylindrical shape so as to be slidable with the hole 45 of the main body of the hanging tool, and at the center of the tightening body 5. A metallic female screw portion 52 screwed onto the tip of the screw portion 22 of the bolt 2 is provided. In the present embodiment, this female threaded portion has a bottom, but as the threaded hole that penetrates, the bolt 2 may project through the threaded threaded hole for nut fixing. The tightening body 5 has a substantially T-shaped longitudinal section, but the lower side of the T-shape is the central hole 45 of the object hanging tool body 4.
The lower surface 53 of the shoulder portion of the tightening body 5 abuts on the upper end surface of the object hanging body 4.

FIG. 2 is a sectional view showing the initial state of adsorption of the embodiment shown in FIG. When the object hanging device main body 4 is pushed down, the suction cup 1 becomes flat and the air inside the suction cup 1 is removed, and the elasticity of the suction cup itself expands the suction cup to reduce the air pressure between the suction cup and the wall, so that the suction cup becomes a wall. Adsorbed on 6. When the tightening body 5 is further rotated, the female screw portion 52 is also rotated, but the object hook body is loosely fitted in the tightening body, and the holding bowl body 3 is loosely fitted in the screw portion of the bolt 2. When the bowl edge 31 of the holding bowl body presses the suction cup surface, the center portion 11 of the suction cup is pulled up into the holding bowl body 3 as shown in FIG. At this time, the bowl edge portion 41 of the article hanging body 4 is still above the suction cup 1.
When the tightening body 5 is further rotated, as shown in FIG. 4, the bowl edge 31 of the holding bowl body 3 strongly presses the inside of the suction cup 1 to expand the volume of the low pressure portion and the bowl of the article holder body 4 is expanded. The edge portion 41 is pressed against the outside of the suction cup to press the periphery of the suction cup and the bowl edge portion 31 of the bowl body 3 is pressed.
At the same time, the inner wall and the outer wall are sealed in the wall 6. When removing the object hook with the suction cup from the wall, the tightening body 5 is rotated in the reverse direction, and the object hook body 4 and the pressing bowl 3 are separated from the suction cup 1 and removed.
