Abstract

The mounting sucker is adapted to be installed on a smooth surface and includes a suction device 10, an intermediate member 20, and a rotating boss 30. As the rotary boss 30 rotates, the central portion of the suction device 10 is pulled out of the smooth surface to form a partial vacuum space. The intermediate member 20 is pressed on the peripheral edge of the suction device 10. The outer circumference of the rotary boss 30 extends beyond the range of the suction device 10, so that the outer circumference of the rotary boss 30 contacts the smooth surface and transmits the force from the object for hooking onto the mounting sucker.

Description

Sucker for Mounting {MOUNTING SUCKER}

The present invention relates to a mounting sucker, and more particularly, to a mounting sucker having a screw device to increase the suction force.

Referring to FIG. 5, in one known device, a suction pad 80 is integrally formed in a fixed structure to which other structures such as cabinets, shelves, towel racks, and the like can be attached. The suction pad 80 is typically made of an elastic material such as PVC and is somewhat dome shaped so that when the suction pad 80 is pressed and in contact with the smooth surface, the surface is essentially smooth by the provided elastic force. And a partial vacuum is created between the suction pad 80 and its face. Such installation means have the decisive disadvantage that only a limited amount of elastic force can be formed in the structure so that a weak fixation force is obtained.

Other known installation means shown in FIGS. 6 and 7 include a suction pad 90 as described above operated by a lever 93 and a cam device 94. At one end of the lever 93, a pulling means 931 for pulling the suction pad 90 from the wall is attached. The pulling means 931 protrudes through an intermediate member whose center is raised from the suction pad 90. The lever 93 has a lever portion for pressing the middle portion. When the end portion of the lever 93 is pushed downward, the lever 93 rotates around the lever point, and the pulling means 931 pulls the suction pad 90 from the smooth surface. This structure has another advantage that the amount of pulling that can be obtained does not depend on the material of construction of the suction pad 90. In addition, when the lever 93 presses the middle portion downward, the middle portion keeps the circumference of the suction pad 90 in close contact with the smooth surface to provide a better sealing state.

However, there are two problems with this known device. In particular, the lever device is complicated to manufacture, relatively invisible, and can only be used to apply a constant magnitude of force to the suction pad.

The present invention has been developed to alleviate and / or eliminate the disadvantages of the installation means according to the prior art.

It is an object of the present invention to provide a mounting sucker which can be firmly fixed to a smooth surface and which is easily operated.

Further advantages and advantages of the present invention will become more apparent from the following detailed description with reference to the accompanying drawings.

1 and 2, a mounting sucker adapted to connect a rack for a hanger is composed of a suction device 10, an intermediate member 20, and a rotating boss 30 used for a smooth surface.

The suction device 10 includes a suction pad 11 made of soft flexible plastic material such as polyvinyl chloride (PVC), and a screw protrusion 12 erected upright in the center of the suction pad 11 and made of hard plastic material. It is provided. The plate 13 is fixed to the lower part of the screw projection 12 to increase the connection strength. The intermediate member 20 provided on the suction device 10 is in the form of a thin dome having approximately the same size as the suction pad 11 of the suction device 10. The intermediate member 20 has a bore 21 made of hard plastic and formed at the center thereof. A pressing edge 22 is formed around the circumference of the intermediate member 20 and is adapted to pressurize the suction pad 11 uniformly. In addition, an annular bearing zone 23 is formed around the bore 21 to provide a constant compressive force to the suction pad 11 when the rotary boss 30 to be described later is tightened.

The rotary boss 30 is a dome made of hard plastic and functions as a lid of the intermediate member 20 and the suction device 10. A tube 31 having an open first end, a closed second end and a screw bore 311 is formed in the center of the rotary boss 30. The first end of the tube 31 penetrates the bore 21 of the intermediate member 20 to receive the threaded projection 12 of the suction device 10. An annular recess 32 is formed around the first end of the tube 31 to receive the bearing zone 23 of the intermediate member 20. A bushing head 33 with a neck 331 is formed at the closed second end of the tube 31 and connected to a rack for a hanger (not shown). A plurality of shaped recesses 34 are formed on the outer surface of the rotary boss 30 so that the installation means can be easily rotated. A plurality of cutouts 35 are formed in the scallop-shaped recesses 34, respectively, to eliminate the sealing state between the suction pad 11 and the smooth surface, if necessary.

2 and 3 show a mounting sucker in use. Suction pad 11 is initially positioned to contact a suitable face 40 as shown in FIG. 2. A suction pad 11 is attached to the face 40, and the rotary boss 30 is placed in a first position spaced apart from the intermediate member 20, and the mounting sucker is lightly attached to the face 40. When the rotary boss 30 is rotated by the user and the rotary boss 30 moves to the second position proximate to the intermediate member 20 by the screw engagement between the screw protrusion 12 and the screw bore 311, the rotary boss 30 is rotated. Force from 30 is transmitted to intermediate member 20 via annular bearing zone 23. Therefore, the pressing edge 22 of the intermediate member 20 presses the circumferential edge of the suction pad 11 to improve the sealing efficiency.

On the other hand, the engagement of the screw projection 12 and the tube 31 of the rotary boss 30 pulls the center of the suction pad 11 in the direction shown by the arrow. A partial vacuum space A (see FIG. 3) is formed to attract the installation means by different atmospheric pressures between the space A and the external atmosphere, improving adhesion and extending longer.

Referring to FIG. 4, one embodiment shows a pair of mounting suckers according to the present invention installed on a smooth surface 40. The soap shelf 50 is caught by the bushing head 33 of the installation means. In position the soap shelf 50 extends 10 cm or more from the smooth surface 40 in the horizontal direction. The soap shelf comprises a pair of keyhole shaped slots 51, each slot 51 having a lower portion having a diameter large enough to pass the maximum diameter of the bushing head 33 of the rotary boss 30, and the bushing head ( It has a narrow portion smaller than the maximum diameter of 33 and larger than the width of the neck 331 of the bushing head 33. As a result, the slot 51 is held firmly in the neck 331 of the bushing head 33 and can pass through the bushing head 33 until it stops, so that the soap shelf 50 is hung on the smooth surface 40. do.

The rotary boss 30 also has an outer peripheral edge extending beyond the outer edge of the suction pad 11 of the suction device 10 so that the outer peripheral edge of the rotary boss 30 contacts the smooth surface 40. do. Thus, in particular, when the soap shelf 50 is heavy due to the soap therein, the inclined force from the soap shelf which may cause the sealing state on the top of the suction pad 11 to break down is the peripheral edge of the rotating boss 30. By being resisted by the contact between the surface and the face 40, the torsional force is transmitted from the soap shelf held on the wall containing the heavy soap to the suction pad 11 to preserve the sealed state. In this way, the suction force at the top can be avoided.

The mounting sucker of the present invention can be used for bonding to any suitable face. The cotton is preferably of the type seen in kitchens and bathrooms, for example, polished cotton, metal surfaces such as aluminum or steel, glazed surfaces such as tiles or plastics such as Perspex ^™ or PVC.

The mounting sucker according to the present invention can be easily manipulated while being firmly fixed to a smooth surface.
