Litt, 6538 Gloria Ave., Van Nuys, Calif. 91406, and Ralph F. Donaldson, North Hollywood, Calif.; said Donaldson assiguor to said Litt Filed Sept. 18, 1968, Ser. No. 760,615 Int. Cl. F16b 47/00y U.S. Cl. 248-363 11 Claims ABSTRACT OF THE DISCLOSURE A suction cup device comprising one or more flexible inner suction cups projecting from and wholly disposed within the interior cavity defined by a flexible outer suction cup wherein there is defined by the interior wall surface of the outer suction cup an annular clearance concentric about each of said inner suction cups, such annular clearance being of suicient dimension whereby, upon compression of the device against an object, the walls of the inner suction cups become substantially coincident with the interior wall surface of said outer suction cup. The suction cup device disclosed may further include a self-sealing air exhaust valve facilitating the exhaustion of air from the aforesaid interior cavity.
BACKGROUND OF THE INVENTION Field of the invention The present invention relates to suction cup devices and more particularly to a plurality of integrally formed suction cup devices having greater holding power for use in moving heavy and hard to manage objects not having convenient support means.
Description of the prior art For some time, it has been known in the art that the addition of a second or auxiliary suction cup to the interior of an outer, or master, suction cup will increase the holding power of the master cup over that obtainable with but a single, master cup. Such a dual configuration is shown in U.S. Letters Patent Nos. 1,298,139 and 1,758, 962 issued to C. M. Wolcott and Carl Miller, respectively. A major disadvantage with similar structures now known in the art is that, due to the construction of such devices, upon compression against an object, the interior suction cup tends to crumple and double up against the interior wall surface of the outer suction cup thereby precluding the more complete exhaustion of trapped air achievable with the construction of the present invention. Furthermore, known devices of a related construction depend entirely upon exhaustion of trapped air from around the distal edges of the master or outer suction cup in order to create the desired negative pressure gradient. Such dependency is not desirable for the simple reason that air remaining trapped within the interior cavity of the device after the walls of the suction cup have Ibecome fully distended precludes the greater negative pressure gradient that could be created if the trapped air could be exhausted. Accordingly, an improved suction cup device has been invented which, in surmounting the shortcomings of the prior art, provides a device capable of greater holding power than that heretofore known.
SUMMARY OF THE INVENTION The present invention is best summarized as a iiexible outer suction cup which wholly encompasses within its interior cavity one or more inner suction cups projecting interiorly therefrom, and an annular clearance concentrically defined about each of said inner suction cups by the interior wall surface of said outer suction cup, wherein ICC said inner and outer suction cups may project from a common base member which may alternately include a selfsealing exhaust valve means to cooperate with the interior cavity of the inner suction cup to facilitate air exhaustion therefrom.
It is a primary object of the present invention to provide an improved suction cup device having an increased holding potential.
A further object of the present invention is to provide a suction cup device constructed to maximize the negative pressure gradient created within the cavity formed by such cups.
The present invention, together with the advantages thereof, will be better understood by reference to the following detailed description in the accompanying drawings.

DETAILED DESCRIPTION OF AN EMBODIMENT Referring to the accompanying drawings and particularly to FIGS. 2, 3 and 4, there is illustratively depicted an embodiment of the present invention. The illustrative embodiment may be viewed as comprising an outer, or master, suction cup 10 and an inner suction cup 12 which project from the common base compression hub 14. A preferred embodiment is constructed so that the wall 7 of the outer cup 10 forms a dome-like structure, the interior wall surface 11 of which defines the interior cavity 13 from which air is exhausted when the device is compressed to create a negative pressure gradient with respect to the exterior ambient pressure. It is found that the eflrciency of the present invention is greatly increased over that achieved by known vacuum cup devices if the outer cup 10 is constructed to have a height to maximum diameter dimensional ratio of no less than 1:3. The wall =9 of the inner cup 12 preferably forms a substantially conical structure having a closed apex 26 which defines the interior cavity 15.
It Ahas been found to be most economical to integrally form the illustrative embodiment in a single unit of some suitably flexible material such as rubber. Flexibility ranges corresponding to readings of 45-65 on the rubber Durometer scale have been found to be preferable for efficient operation of the present invention.
In the illustrative embodiment, the outer cup 10* and the inner cup 12 integrally intersect one another and project from the common base compression hub 14. In the formation of a single device, it has been found preferable to concentrically dispose the inner and outer cup 10 and 12 and the compression hub 14 about a common axis 17.
It has rbeen found that the proximately adjacent anrular undercut portions or clearances, 16 and 18 defined by the interior wall surface 11 of the outer cut, are important improvements in maximizing the negative pressure gradient generated by compression of the device against an object. It has been found advantageous to form t-he interior beveled surface of the clearance 16 at an acute angle a of approximately 16 with the projection of an imaginary plane passing perpendicularly through the axis 17. Similarly, it has been found to be advantageous to form the annular clearance 18 at a larger acute angle of approximately 35 with the projection of an imaginary plane perpendicular to the axis 17. As illustrated in FIGS. 4, and 6, the tapered wall 9 of the inner cup 12 is designed to have a lesser flexural strength than the Wall 7 of the outer cup 10 so that upon compression against either a flat or a curved surface, the inner cup wall is distended into the clearances 16 and 18 to become substantially coincident with the interior wall surface 11 of the outer cup 10. As depicted in the illustrative embodiment, the lesser `flexural strength of the wall 9 may be achieved through thinner wall construction than that of the Wall 7. Thus, the two bearing surfaces, or walls of the inner and outer suction cups, cooperate under compression to form an effective single vacuum cup. The device thus collapsed combines the holding power of the multiple cup unit, yet achieves the maximized air exhaustion achievable with the single cup unit. While it is considered desirable that the base compression hub 14 have a relatively wide cross-sectional dimension to insure maximum flattening of the cups, it has been found preferable that such dimension be less than the diametrical dimension of the inner cup 12 when distended into the clearance 16 in order to avoid trapping unexhausted air within the area defined by the clearance 16, 18 and the inner suction cup wall 9.
Referring now with particularity to FIG. 4, t-he present invention embodies several novel concepts for insuring virtually complete exhaustion under compression and for preserving the integrity of the negative pressure gradient thereby created. For example, it has been found preferable to curvilinearly shape the apex 26 of the inner cup 12 to extend above the clearance 18. In like manner, the distal edge 20 of the clearance 16 is curvilinearly formed to facilitate air exhaustion from the respective cavities 13 and l15. It has also been found preferable to form the distal edges 22 and 24 of the outer and inner cups 10 and 12, respectively, in a curvilinear configuration to preserve the integrity of the negative pressure gradient created across the outer suction cup in the illustrative embodiment such curvilinear configurations are portions of substantially circular arcs.
Because of the high degree of efficiency of the holding force created by the previously described device, it has been found desirable to include the tab 38 at the distal edge 22 of the outer cup 10 for the purpose of lbreaking the vacuum seal when release is desired.
Having thus described the basic unit of the present invention, with reference now to FIGS. 7 and 8, there is depicted an additional embodiment of the present invention wherein a single master or outer oup 10 encompasses a plurality of the previously described inner cups 12 to maximize the novel features of the present invention. While the number of inner cups 12 may be left to choice, in each case they are concentrically disposed within the previously described clearances 16 and 18 annularly delined 'by the interior wall surface 11 of the outer cup 10.
With reference to FIG. 9, substantially complete air exhaustion from the cavities 13, of the illustrative embodiment of the present invention may be achieved through the self-sealing ex-haust valve comprised of the substantially conical exhaust chamber 34 and the substantially cylindrical exhaust chamber 36 axially defined through the base compression hub 14. The exhaust valve may be constructed of a flexibly soft material having rubber-like characteristics so that upon compression of the device, air trapped within the cavities 13, 15 may be exhausted not only around the distal edges 22, 24 but also t-hrough the chambers 34, 36 to the atmosphere. It has then been found that upon release of the compressive force, the negative pressure gradient thereby created across the outer suction cup 10 acts on the device to seal off the chambers 34, 36 against the further introduction of air at the exterior ambient pressure.
As illustratively depicted in FIGS. 1 and 2, the present invention embodying the features hereinbefore described may be individually attached to handles or attached in groups to holding platforms 28 for convenient use in handling or moving large or bulky objects. One form of attachment is depicted in FIG. 2 wherein a threaded bolt 30 is embedded in the compression hub 14 to project therefrom through the platform 28 to lbe secured by means of the nut 32. It will 'be apparent that the same result may be achieved by embedding any of various types of nuts, such as a Tinnerman nut for example, within the hub 14 through which may be threaded an affixing bolt or screw. The platform 28 may be provided with suitably spaced optinings 40 to permit access to the re lease tabs 38 forming a part of suction cups interiorly affixed to the platform.
There has thus been described a novel, improved suction cup device constructed to maximize the advantages inherent in multiple suction cup configurations and to overcome the disadvantages of such configurations presently known in the art.
