Description

Suction bonding device

technical field

The utility model relates to a suction bonding device. More particularly, but not specifically limited to, the present invention relates to a device having a suction cup and a hook. The unit is usually attached to the bathroom wall tile or window or shower screen, for example face towels, bars of soap, shower covers or other items can be hung on the unit.

Background technique

It is known to use suction cup devices to secure items such as items to bathroom wall tiles. For example a small soap container may include two such suction cups. Suction cups typically include a bulbous protrusion in the center that passes through a small hole in the side of the soap container. It is also known to configure a hook on the suction cup to hang the article. The hook can be integrally molded with the suction cup, or be fixed to the suction cup after being made of non-flexible material.

These and other known suction cup devices are more securely fastened to the surface if the suction cup face and/or the surface itself is wetted prior to attachment. However, air can get into the space between the suction cup and the surface, so the unit comes loose and usually falls to the floor. Since there is no visible indication of air entering the space, dropping of the device always occurs without prior warning.

Utility model content

The purpose of this utility model is to overcome or significantly alleviate the above-mentioned disadvantages, generally to provide an improved suction bonding device.

A suction bonding device disclosed herein includes:

a sucker;

a rod extending from the suction cup;

a body through which said rod passes;

a spring interacting with the rod and the body, biasing the suction cup towards the body;

A locking mechanism interacting with the body and rod selectively secures the rod relative to the body against deflection of the spring.

Preferably the device also includes a handle movably connected to the body and interacting with the locking mechanism.

The device preferably also includes a visible indicator fixed relative to the rod for indicating when the spring is drawing the suction cup toward the body.

The visible indicator is preferably attached to or integral with the rod.

The visible indicator is preferably a colored ring.

The body preferably includes a neck through which said rod extends, and when the spring has drawn the suction cup towards the body, the colored ring protrudes beyond the neck.

The locking mechanism preferably comprises a slide plate having a tongue extending therefrom and a cam surface; a pawl attached to the handle wherein the pawl engages the cam surface; and wherein the neck has a hole through which the tongue passes. The hole interacts with the rod.

The tongue preferably interacts with a hole in the colored ring.

The handle is preferably made into a hook shape.

The lever preferably has a button against which the handle can be pressed.

Detailed ways

In the drawings there is shown a suction bonding device 10 comprising a body 11, usually compression molded from rigid plastic.

The body 11 has a neck 16 through which a rod 19 extends. On top of the rod 19 is arranged a button 13 .

A helical compression spring 18 is placed under the button 13 and surrounds the upper part of the rod 19 . The lower end of the helical compression spring 18 bears downwardly on the body 11, thereby biasing the rod 19 upwardly.

Around the upper part of the compression spring and fixed relative to the button 13 is a colored ring 17 . Ring 17 may be glued or bonded to the downwardly projecting annular lip of button 13 .

At the bottom of the rod 19 there is a flange 20 to which a suction cup 14 is attached. Suction cup 14 is made of a smooth, flexible material, such as rubber, silicon, or other suitable flexible, substantially water-impermeable material. The suction cup 14 has a release protrusion 15 extending from its periphery.

In the configuration shown in FIG. 2 , the suction cup 14 is biased upwardly towards the body 11 by the spring 18 .

The handle 12 is pivotably connected to the body 11, and the handle 12 is shaped like a hook. The claws 26 extend through a pair of webs 29 integral with the body 11 . Each connecting plate 29 has a large hole that allows the claws 26 to rotate freely. The jaws 26 are shaped to fit snugly in likewise shaped keyways formed on the handle 12 . The jaws 26 move together with the handle 12 .

The sliding plate 23 is disposed between the connecting plates 29 . Slider 23 has a cam surface 25 on the inner edge of the hole therethrough through which pawl 26 engages the cam surface.

The slide 23 has a tongue 24 which passes through a hole 22 in the neck 16 of the body 11 . A hole 21 is also provided between the colored ring 17 and the button 13 , which interacts with a tongue 24 .

When in the configuration shown in Figure 2, the device is substantially free of adhesion. In order to create an adhesive effect, the button 13 can be pressed downwards. Such pressing can use people's thumb to directly press the button, and a more common method is to use the movement of the handle 12 to press the button to the state shown in FIG. 3 . When the button 13 is pressed down, the suction cup 14 is pushed away from the body 11 by the neck 19 . If the suction cup has been attached to the ceramic tile, the button 13 can be pressed, for example, with the force of the thumb, and at this moment the device will be in the form shown in Figure 4. However, it is by design that the handle 12 is pushed down on the button 13 before the suction cup 14 is abutted against a surface.

When the handle 12 is pushed down to bring the device into the configuration shown in FIG. 3, the pawl 26 is pushed against the cam surface 25, thereby allowing the tongue 24 to pass through the two holes 22 and 21. As a result the lever 19 is locked down against the pressure of the spring 18 . The suction cup 14 is then pressed against the surface, after which the handle 12 can be raised, whereby the pawl 26 is drawn back on the cam surface 25, the slide disengages the neck 16 and the tongue 24 exits the hole 21. Consequently, the lever 19 springs back to the position shown in FIG. 4 due to the action of the compression spring 18 . This creates a vacuum suction between the suction cup 14 and the surface against which it rests. If desired, the suction cup 14 and/or the surface against which it rests may be pre-moistened.

Over time, air will enter the space between the suction cup 14 and the surface it is bonded to. Compression spring 18 causes rod 19 to protrude gradually outwards from neck 16 and colored ring 17 can be seen. When this is seen, one can easily push down on the button 13 or press against the button 13 with the handle 12 in order to remove the air between the suction cup and the surface.

Since the handle is made into a hook shape, objects can be hung on it.

It should be understood that modifications and changes can be made by those skilled in the art without departing from the basic spirit of the present invention. For example, instead of providing a visible indicator structure directly on the rod, other extensions or pins extending from the suction cup can pass through another part of the body 11 .
