  Vacuum suction apparatusUSPTO Application #: 20060086872Title: Vacuum suction apparatus Abstract: A vacuum suction apparatus with adjustment lever is disclosed. The structure of the vacuum suction apparatus includes a suction cup and a wheel base, which has a receptacle being attached by the suction cup from underneath, a semi-circular cogwheel being fixed on top of the receptacle, and an adjustment lever pivotally connected through an opening. The adjustment lever has a pinion on the bottom end, where the gearing of the pinion is to fit against corresponding gearing on the vertically erected rack at the center when the lever is in locked position. The upper portion of the lever also has a suction lock/release that allows the user to manually adjust the angle of the lever by pegging onto scooped cogwheel with a slider, so the suction strength can be adjusted desirably for continuously holding onto the same spot in extended use.

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a vacuum suction apparatus, and particularly to a suction cup with an innovative lever that allows a user to manually adjust the suction strength of the suction cup for continuously holding onto the same spot in extended use. [0003] 2. The Related Arts [0004] Suction cups, also known as vacuum cups, are now well used by office and household users, as a suction cup can be used to hold an article easily and elegantly on a smooth vertical surface, especially on tile or glass surfaces. Further, it does not leave holes or residue on the original surface after its removal, unlike conventional wall nails or adhesive fasteners. Suction cups are now widely used for making soap holders, razor holders, radar detector holders, sign holders, etc., which are only a few of the common uses. [0005] Suction is a force that is derived from atmospheric pressure when air is drawn out from an enclosed space forcing two surfaces to stick together. It is found that a suction cup will normally experience fatigue and deformation after extended use, resulting in gradual loss of elasticity and suction strength. This is the main reason why suction cups tend to fall off after using them for some time. However, with a uniquely designed adjustment lever, the suction force of the suction cup can be desirably adjusted by the user to effectively prolong the product life. [0006] Also, this type of suction cup shall be able to find new applications in automobiles. At the present, most mobile phone or PDA holders for automobiles are made with a clipper that is to be attached onto the outlet of the air conditioning or the cigarette lighter in an automobile. Such clipper does not fit on all automobiles, as some are better suited than others. The truth is that the driver shall be able to watch the display screen of the electronic device with ease while still driving the automobile. If the mobile phone or PDA can be attached onto the wind shield glass of the automobile with a suction cup and suitably adjusted for viewing angle, the driver does not have to be strained in order to watch the display screen below the dash board, where the conventional holders of mobile phones or PDAs are installed, so the drivers will not be distracted from driving in the future. SUMMARY OF THE INVENTION [0007] A primary objective of the present invention is to provide a vacuum suction apparatus with a unique adjustment lever. The vacuum suction apparatus comprises a suction cup and a wheel base over the suction cup, where the wheel base has a receptacle being attached by the suction cup from underneath, a cogwheel being fixed on top of the receptacle, and a lever being pivotally connected through an opening, so that the suction strength of the suction cup can be manually adjusted by the user through the action of the lever for securing a reliable mounting on a smooth surface. [0008] Another objective of the present invention is to provide a vacuum suction apparatus that enables the effective prolonging of the product life through the adjustment of the suction strength by means of an adjustment lever, whereby the adjustment lever can be initially set with a small angle, and as time progresses the adjustment angle can be gradually increased so that the suction cup can keep holding on to the same spot in extended use, that means by gradually increasing the suction strength setting the suction cup is able to counter the natural wearing down of elasticity over extended use. [0009] A further objective of the present invention is to provide a vacuum suction apparatus that is suited for mobile phone or PDA holders in automobiles. [0010] To achieve the above objectives, the structure of the unique suction apparatus includes a suction cup and a wheel base attached over the suction cup, where the wheel base has a semi-circular cogwheel fixed over a receptacle, and an adjustment lever is pivotally connected through a slot opening. The adjustment lever has a pinion on the bottom end, which has gearing on the outer edge that are to fit against corresponding gearing on the vertically erected rack linked to the suction cup. The top of the lever has a suction lock/release, wherein a slider is assembled that allows the adjustment angle of the lever to be manually set. With the action of the lever and the suction lock, the suction strength of the vacuum suction apparatus can be adjusted desirably for continuously holding onto the same spot in extended use. [0011] The advantages of using the unique suction cup over the conventional suction cups are as follows: (1) High efficiency: as the suction force can be manually adjusted to prolonging the product life. (2) Alternative for conventional holders: as these suction cups, unlike conventional holders, do not leave holes or residues on the original surface after removal. (3) Add-on value: easy to use and remove. [0012] The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention. BRIEF DESCRIPTION OF THE DRAWINGS [0013] FIG. 1 is a perspective view of the present invention; [0014] FIG. 2 is an exploded view of the unique suction cup with adjustment lever; [0015] FIG. 3A is a sectional diagram of the structure of the present invention; [0016] FIG. 3B is another sectional view of the action of the adjustment lever to adjust the suction strength in accordance with the present invention; [0017] FIG. 4 is another preferred embodiment of the invention; and [0018] FIG. 5 is a user application diagram of the preferred embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [0019] Referring to FIGS. 1 and 2, a vacuum suction apparatus in accordance with the present invention includes a suction cup 1, and a wheel base 2 that is installed over the suction cup 1, and a rack 11 is vertically erected from the center of the suction cup 1 passing through the wheel base 2, wherein the suction cup is formed by rubber or polyvinyl chloride (PVC) material, and the rack 11 is made out of material harder than the suction cup 1. [0020] Referring to FIG. 3A, the wheel base 2 has a receptacle 21 attached by the suction cup 1 from underneath, a cogwheel 22 being fixed over the receptacle 21, and an adjustment lever 23 pivotally connected through a slot opening. The receptacle 21 is a circular body with hunched back toward the center, with a slot opening 211 at the center that allows the rack 11 to pass through to the outside, also passing through the inner space of the cogwheel 22, where an adjustment lever 23 is pivotally connected having a pinion 231 on one end. Once assembled onto the cogwheel 22, the lever 23 is positioned such that first gearing 231 on the outer edge of the pinion 231 is to lock against second gearing on the vertical rack 11 linked to the suction cup 1. By cranking the lever 23 down toward the wheel base 2, the central part of the suction cup 1 is pulled upward to increase the suction strength. Continue reading...
