うこととなる。By the way, in the cover type suction cup 70 as described above, it is difficult to achieve both the strength of the suction cup main body 72 and the adhesion to the surface 81 to be sucked. In other words, when the suction cup body 72 is formed of a relatively hard synthetic resin, the suction cup body 72 has high strength, but the suction surface 71 is not easily deformed, and the adhesion to the suction surface 81 is low. . Therefore, external air enters into the low-pressure space 82 through a gap (air passage) generated by fine irregularities inherently present on the suction surface 71 and the suction surface 81, so that the suction force is relatively short. Is lost, and the cover-type suction cup 70 is separated from the suctioned surface 81.

る。On the other hand, when the suction cup body 72 is formed of a relatively soft synthetic resin, the adhesion between the suction face 71 and the suction face 81 is improved, but the strength of the suction cup body 72 is low. Therefore, the suction cup main body 72 is easily deformed by the load such as the weight of the article hooked on the hook portion 80, and the air enters into the space 82 with the deformation, and the cover-type suction cup 70 is detached from the suctioned surface 81.

A low-pressure space c is created between the suction surface 4 and the suction surface b, and the sealing ring 15 is pressed against the suction surface b by the annular pressing portion 18 via the suction body 2. That is, since the projecting portion 19 of the annular pressing portion 18 comes into contact with and presses the top of the annular ridge 7, the suction body 2 at this portion is deformed so as to be crushed, and the groove bottom portion of the annular groove 6 becomes the sealing ring. Press 15. As a result, the sealing ring 15 made of a relatively soft elastic body is also deformed, and the surface to be attracted b

の吸着力が維持される。In the cover-type suction cup 1 described above, since the suction cup body 2 is made of a relatively hard material, the suction cup body 2 can sufficiently withstand the weight load of a hooked article and the like. Since the sealing ring 15 made of a substantially soft elastic body is in close contact with the suction cup body 2 and the suctioned surface b to enhance the airtightness of the space c, the pressure in the space c may not rise due to intrusion of external air. Thus, the desired suction force is maintained for a long period of time.

に扁平に変形することも防止される。Further, since the annular ridge 7 accommodating the sealing ring 15 is sandwiched between the inner cylindrical portion 20 and the outer cylindrical portion 21 and held at a predetermined width, the knob 10 is turned to rotate the suction main body 2. When the central portion is pulled up, the suction body 2 is not deformed such that the groove width of the annular groove 6 increases as the suction body 2 is pulled inward. Therefore, the sealing property between the sealing ring 15 and the suction cup body 2 is always kept good, and a stable suction state is obtained. Further, it is possible to prevent the sealing ring 15 from being unnecessarily flattened by pressing from the rear side.

May shift slightly. On the other hand, in the cover-type suction cup 1, the inner cylinder 2
The gap a existing between the front end of the outer cylinder 21 and the suction body 2 disappears in the suction state, and the front ends of the inner cylinder 20 and the outer cylinder 21 press the back surface 5 of the suction main body 2. Therefore, the suction surface 4 at a position corresponding to the pressed portion is pressed against the suction surface b. As described above, not only the soft sealing ring 15 but also a part of the hard suction cup body 2 is adsorbed in a state of being in close contact with the suctioned surface b, so that the cover type suction cup 1 is prevented from shifting. Is also played.

In the above description, the example in which the annular groove and the annular ridge are formed in the suction cup main body is shown. However, the sucker main body may be made thicker so that the annular ridge does not protrude behind the annular groove. Further, the cross-sectional shapes of the annular groove and the sealing ring are not limited to those described above, and are arbitrary. Further, in the above, the "tensile means" referred to in the present invention
Is constituted by a knob 10 screwed with the protruding shaft 9 (that is, a “screw-type” pulling means is adopted), but the type of the pulling means is not limited to the screw-type, but is arbitrary, for example, as shown in a conventional example. A simple lever type (lever type) pulling means may be employed.

することが可能となる。As described above, in the cover-type suction cup according to the present invention, the suction cup body is formed of a relatively hard synthetic resin or the like, and the sealing ring is formed of a material for forming the suction cup body. A relatively soft material formed of an elastic body such as a synthetic resin can be used. By doing so, the airtightness of the space generated between the suction surface and the surface to be suctioned during suction is increased while increasing the strength of the suction cup body so as to sufficiently withstand the weight load of the hanging article and the like. Thus, it is possible to provide a cover-type suction cup in which the suction force is maintained for a long time.
