Patented Apr. 18, 1939 UNITED STATES-PATENT OFFICE soc'rrou noummo Frederick A. Wayne, bets-cit, Mich.
Application June '2, 1931, Serial No. 140,793
' 2 Claims. (01. 248-362) This invention relates to improvements in suction mountings, and refers to mountings intended I for use upon the legs of comparatively heavy articles to be held in position upon highly finished 5 surfaces, as for instance carrier frames to be mounted upon the tops of automobiles. At the present time suction mountings consisting of inverted cups are frequently employed for holding articles to which they are attached upon other 10 articles. These mountings, however, are open to the grave objection that when subjected to sudden loads they are apt to collapse in which case the central portion of the cup suddenly contacts the surface on which it is mounted and is l5 very liable todent or mar a highly finished pressure is exerted upon the mountings even if the latter are utilized upon vehicles where they are also subjected to vibration.
Another object of the invention is to provide a suction mounting consisting of an inverted cup having a central downwardly projecting resilient pad which normally terminates above the underside of the cup so that the bottom of the pad will contact the surface on which the mounting 30 is arranged and prevent complete collapse of the cup when the mounting is subjected to a sudden load.
Another object of the invention is to provide such a suction mounting wherein an air space is maintained at all times within the cup and around the pad to preserve the suction hold of the mounting.
Having thus briefly stated some of the major objects and advantages of the invention, I will 40 now proceed to describe preferred embodiments thereof with the aid of the accompanied drawing in which:
Figure 1 illustrates a sectional view of the suction mounting when not in use, and
45 Figure 2 is a similar view o1 the mounting in use.
Figure 3 is a plan view of a carrier to which the mountings are applied to retain it upon the top of an automobile, and
5 Figure 4 is a side view of Figure 3 partly in section.
Figure 5 is a partial sectional view showing a slight modification of the mounting.
Referring to the drawing; l designates the 55 roof of a vehicle on which a carrier 2 is arranged.
The latter consists. of a rectangular frame 3 having reinforcing strips 4 secured longitudinally upon the inner faces of its sides intermediately of the length of the latter. 5 denotes diagonal braces across the inside of the frame 3 from 5 the extremities of the strips 4 to the frame ends. The upper edge faces of the strips 4 and braces 5 terminate below the upper edges of the frame 3 so that a box (not shown), or other structure,- may be supported upon the said edge faces of the strips 4 and braces i with its base beneath thetop of the frame 3. Secured to the corners of the latter and projecting downwardly therefrom are legs 6, which, in the present case, are externally threaded at their lower extremities to 16 engage correspondingly threaded openings 1 formed in upwardly projecting bosses 8 integral with the suction mountings 9.
Referring now to the mounting '9. l0 denotes an inverted suction cup which usually terminates 20 at its lower extremity in an annular base ll of increased width. The cup l0 may also be reinforced by substantially vertical ribs projecting from its inner face intermediately of its height. Extending downwardly from the under- 26 side of the cup l0 concentric with the boss I is a neck ll of a pad IS. The main portion of the latter which extends from the bottom of the said neck is of enlarged cross section, normally terminates above the base ll of the cup l0, and its 30 underside normally lies parallel with the underside of the said cup base.
The mounting 9, including the cup it, ribs I2 and boss 7, are moulded in one piece of rubber or other resilient composition, and the pad I5 including its neck It may either be separated moulded, also of a resilient material such as rub-' ber, and adhesively secured both to the underside of the cup in and also to the ribs i2 as indicated at M, or else the entire mounting 9 and pad I5 40 may be moulded together in one piece.
Due to the fact that the cup base ll first contacts the surface towhich the mounting'is to be applied the cup I 0 becomes somewhat distorted,' and therefore intermediate'iy of its height the cup is somewhat outwardly flexed before the pad I5 contacts the said surface. Conseguently an air space is always maintained within the cup and around the pad to insure the retention of a suction hold. It may also be pointed out that whereas in the construction described the pad l5 joins the ribs l2 for a short distance along the latter the spaces, between the ribs afford free air passage at all times from the annular space within the bottom of the cup to the space around the neck I 4. In the modified arrangement shown in Figure 5 the pad lid is of somewhat smaller the mounting rests from any sudden blow that it might receive due to the collapseof the cup if that said pad were omitted.
While in the foregoing the preferred embodiments of the invention have been described and shown, it is understood that the construction is .subject to such further alterations and modifications as fall. within the scope of the appended claims.
What I claim is:
1. A suction mounting comprising a resilient inverted cup the lower annular face of which is adapted to rest upon a surface and maintain a suction grip thereon, a stepped resilient pad dependingly mounted within the cup and its base being adapted to bear upon said surface, the
upper portion of the pad being of smaller perimeter than its lower portion and the upper extremity of the lower portion of the pad around its entire perimeter lying adjacent the interior of the cup, whereby an upper air space is formed around the upper pad portionand a lower air space around the lower pad portion, said cup and the lower portion of the pad being adapted to be pressed together around the entire pad perimeter by sudden downward pressure exerted upon the mounting whereby the underside of the upper air space is closed and complete collapse of the cup is prevented, and means on the upper side of the cup to receive an article to be supported.
2. A suction mounting comprising a resilient inverted cup the lower annular face of which is adapted to rest upon a surface and maintain a suction hold thereon, a plurality of inwardly disposed radial ribs formed inwardly of the cup intermediately of its height, a circular resilient pad stepped intermediately of its height dependingly mounted within the cup and having a base adapted to bear upon said surface, the upper portion of the pad being of smaller diameter than the lower portion and both pad portions being annularly spaced from the interior of the cup thereby forming upper and lowers air spaces around them, the upper extremity of the lower portion of the pad bearing against said ribs between which passages are formed normally connecting the upper and lower air spaces, said cup and the lower pad portion being adapted to be pressed together around their entire circumferences by sudden downward pressure exerted upon the mounting thereby closing the underside of the upper air space, and means on the upper side of the cup to receive an-article to be supported.
