DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction cup in which the closed edge of the suction cup is double-pressed to keep the pressure inside the suction cup low.
The present invention relates to a hook with a suction cup for fixing articles for a bathroom, a kitchen, a household and the like to a wall.

[0002]

2. Description of the Related Art Conventionally, a hook with a sucker for fixing a hook, which is used as a tool for hanging a shower fountain, a ladle or the like on a wall of a bathroom such as a bathroom or a kitchen, is used as a tool with a suction cup. Japanese Patent Publication No. 64-10 by the present applicant
No. 685 is known. This is equipped with an inner holding bowl and an outer holding bowl that invert the bowl-shaped suction cup upside down and adsorb it to the wall and press the edges of the suction cup in a ring-shaped manner at the bottom of the suction cup. The low pressure in the suction cup is maintained by the pressure contact.

[0003]

However, in this type of a hook with a suction cup, the pressure contact of the suction cup is caused by the rotation of an outer pressing bowl body in which the other end of a bolt having one end fixed to the suction cup is screwed. On the other hand, it can be freely performed, but the hanging support portion formed integrally with the outer holding bowl body also has a disadvantage that the object is not sufficiently supported due to the inclination due to the rotation. An object of the present invention is to overcome the above-mentioned drawbacks and reliably maintain the low pressure of the suction cup, and to accurately support the object by suspending the object to be hooked so that the hanging support portion is correctly positioned in the vertical direction. It is another object of the present invention to provide a novel tool with a suction cup.

[0004]

In order to overcome the drawbacks of the above-mentioned conventional suction cups, in a tool holder with a suction cup according to the present invention, a bolt having a head fixed to the suction cup is attached to a holding bowl body and a body of a tool hook. By loosely penetrating through the central holes formed in each of the bolts, a tightening body, which is concentrically placed on the hanging body, is screwed into the tip of the screw portion of the bolt via the female screw portion. Then, the hanging member main body is rotated to a desired normal position and tightened by the tightening body to fix the hanging member supporting portion to the normal position.

[0005]

When the object holder with the suction cup according to the present invention is pressed against the surface to be suctioned, such as a wall, and the tightening body is rotationally tightened, the holding bowl body and the object holder body approach the surface to be suctioned, such as the wall, and the bowl of the holding bowl body. The edge and the edge of the bowl of the hanging tool main body are pressed against the inside and outside of the suction cup in a circular shape, respectively, and then stopped. At this time, when the position of the hanging support portion provided in a part of the hanging tool main body is not vertically supporting the object to be hooked and is inclined from the vertical direction, the tightening body is rotated and loosened, By properly correcting the position of the hanging support portion and then tightening the tightening body, the hooking target can be hooked to the correct position without detaching the suction cup from the suctioned surface.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a longitudinal sectional view of a main part showing a suction ready state of a hook with a suction cup according to an embodiment of the present invention, FIG. 2 is a longitudinal sectional view of a main part showing an initial state of suction, and FIG. FIG. 7 is a vertical cross-sectional view of a main part showing a state in which the press-contact of the presser bowl body has increased and swelled. 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 bolt head 21 of a bolt 2 made of a material such as metal or hard resin is buried and fixed at the center thereof. I have. The holding bowl 3 is formed of a hard material such as a thin metal plate, phenol, urea resin, etc., and the bolt 2 is loosely inserted into the bowl center hole 32 formed in the holding bowl 3, and is placed on the suction cup as shown in the figure. Mount concentrically. The hanging tool body 4 is formed of methacrylic resin or other hard material,
At the center thereof, a hanging hole central hole 45 is formed concentrically with the metal bolt 2. The hanging tool main body 4 is mounted concentrically on the holding bowl 3. The hanging tool body 4 has an inverted bowl shape, and the circular diameter of the bowl edge 41 is larger than the diameter of the circular bowl edge 31 of the holding bowl body 3 but smaller than the diameter of the suction cup 1. On the outer periphery of the hanging tool main body 4, a hanging object support portion 43 for hooking and supporting an object to be hooked, for example, a shower fountain portion, is provided, and a groove for hooking a string or the like is provided around the hanging tool main body 4. Sometimes it is. The tightening body 5 that is concentrically placed on the hanging tool main body 4 is made of metal, methacrylic, or other hard material, and the lower part of the tightening body sliding portion 51 is cylindrical on the outside. The hanging member 5 is adapted to slide with the hanging member central hole 45 of the hanging member main body 4.
Is provided with a female screw part 52 made of metal which is screwed to the tip of the bolt screw part 22 of the bolt 2. In the present embodiment, the female screw portion 52 has a bottom. However, as a penetrating screw hole, the bolt 2 may be screwed through the penetrating screw hole and fixed to a nut. Although the longitudinal section of the tightening body 5 is substantially T-shaped as shown in the figure, the lower side of the T-shape slides into the hanging member central hole 45 of the hanging member body 4, The lower surface 53 of the tightening member, which is the lower surface of the shoulder of the tightening member 5, abuts on the upper end surface of 4.

FIG. 2 is a sectional view showing an initial state of suction in the embodiment shown in FIG. When the hanging tool main body 4 is pushed down, the suction cup 1 becomes flat, the air in the suction cup 1 is eliminated, and the suction cup 1 tries to expand due to the elasticity of the suction cup itself, and the air pressure between the suction cup 1 and the wall 6 decreases. The suction cup 1 is attracted to the wall 6. Next, when the tightening body 5 is rotated, the female screw 5
2 also rotates together, but the hanging tool body 4 is loosely fitted to the tightening body 5 and the holding bowl 3 is merely loosely fitted to the screw portion of the bolt 2, so that it is lowered without rotating. Then, when the bowl edge 31 of the holding bowl body 3 presses the suction cup surface, the center 11 of the suction cup at the center of the suction cup 1 is pulled up into the holding bowl body 3 as shown in FIG. At this time, the bowl edge 41 of the hanging tool main body 4 is still separated 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 3 strongly presses the inside of the suction cup 1 to increase the volume of the low-pressure portion, and the bowl of the hanging member body 4 while expanding the volume of the low-pressure portion. The edge portion 41 is pressed against the outside of the suction cup, and the periphery of the suction cup 1 is sealed to the wall 6 with the inside and outside of the wall 6 together with the bowl edge portion 31 of the holding bowl 3. When removing the hook with a suction cup from the wall 6, the tightening body 5 is rotated in the reverse direction, and the hook body 4 and the holding bowl 3 are separated from the suction cup 1 and removed.

[0008]

According to the present invention, the central part, which is the main airtight holding portion of the suction cup, is first pressed against the edge of the holding bowl body, and then the outer periphery of the suction cup is pressed against the edge of the bowl of the hanging tool body. Since the residual airtight holding part is pressed against the load, the load is mainly applied to the suction hook body and the wall near the suction cup pressure contact point at the edge of the bowl of the hanging tool main body when the load is received by the hook. In order to bear, not only is the airtightness of the airtight holding portion in the suction cup central part maintained, and the suction effect is not easily reduced,
If the hanging support that supports the object to be hooked is tilted from the vertical direction and is not in the correct direction when hanging, simply rotate the tightening body in the direction opposite to the tightening direction without separating the suction cup from the wall. After simply rotating the object hanging tool body loosely fitted with the tightening body to correct the inclination, the tightening body is tightened again to easily adjust the hooking target correctly in the vertical direction. It has an excellent effect that it can be done.
