BY AND a ADAMEC United States Patent NON-SKID DISHES Oscar A. Yost, New York, and Gilbert Adamec, Bronx, N. Y.; said Adamec assignor to said Yost Application September 3, 1953, Serial No. 378,384
1 Claim. (Cl. 6515) This invention relates to non-skid dishes.
It is an object of the present invention to provide dishes having projections thereon adapted to engage the supporting surfaces in a manner that they will not readily skid from such surfaces when used on ships at sea or air liners.
It is another object of the invention to provide on dishes projections which will not only serve to prevent the skidding of dishes upon surfaces, but which will make easy the drying of the dishes on the drying racks due to the air gap permitted under the dish upon these dishes with the projections being stacked in abutment with each other on the drying racks.
It is another object of the invention to provide dishes with a non-skid device which is adjustable to present either a smooth material or in another position rubber so as to provide further friction when necessary to keep the dishes from skidding and wherein the adjustment of these elements can be readily and easily effected and with the rubber portion having an undercut opening to provide a vacuum type tight grip upon the supporting surface.
Other objects of the invention are to provide a nonskid dish for use on ships at sea and on air liners, which is of simple construction, inexpensive to manufacture, has a minimum number of parts, compact, durable, sanitary and easy to clean and eflicient and effective in use.
For other object and a better understanding of the invention reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:
Figure 1 is a collective and perspective view of a cup and a saucer having projections respectively thereon to prevent the skidding of the saucer or cup upon the surface on which either of them is rested;
Fig. 2 is a sectional view of an ash tray having projections on the bottom of the same to prevent the skidding of the same over the supporting surface;
Fig. 3 is a fragmentary perspective view of a pointed form of projection;
Fig. 4 is a fragmentary perspective view of a still further form of projection of truncated formation;
Fig. 5 is a perspective view of a still further form of projection and of pyramidal shape;
Fig. 6 is a fragmentary elevational view of a pitcher having a still further form of projection on the bottom of the pitcher and which is adjustable to present either a rubber vacuum cup surface or a smooth rounded surface;
Fig. 7 is an enlarged fragmentary sectional view of the projection adjusted to present a smooth surface for engagement with a supporting table surface;
Fig. 8 is a fragmentary projection in sectional view of the ball rotated to present the rubber vacuum cup connection with the surface in order that the pitcher can cling to an inclined supporting surface.
Referring now to the figures and in particular to Fig. 1, 10 represents a cup having a bottom 11 and a handle 12. On the bottom 11 are three depending projections 2,750,769 Patented June 19, 1956 13 circumferentially spaced about the periphery of the bottom 11 and of rough surface to prevent the cup from sliding on a smooth supporting surface or in a saucer 14. This saucer may have similar projections 15 on the bottom thereof for engagement with the table surface. The projections 13 will engage the interior of the saucer 14 and will tend to prevent the movement of the cup within the saucer and the projections 15 will engage a smooth table or supporting surface in such a manner as to prevent the sliding of the saucer upon the surface. The ends of the projection can be left unfinished and have a ceramic or soft engaging surface, or, if desired, the ends of the projections can be frosted. Also, the projections can have sand or grit upon the same to make them rough.
In Fig. 2 there is shown an ash tray having the usual indentations on the flange as indicated at 16. This ash tray is indicated generally at 17 and has a bottom 18 thereon with projections 19 constructed similar to the projections 13 and 15 in the form of the invention shown in Fig. 1. These projections are similarly roughened to prevent slipping or skidding of the ash tray upon the surface upon which the ash tray is supported.
In Fig. 3, there is shown a different form of projection. The projection is simply pointed to provide a sharp point to engage a wood or rough table supporting surface. This sharp point is indicated at 20 and is such as to positively prevent the sliding of the dish on the table surface.
In Fig. 4, there is shown a truncated projection 21 having a flat bottom surface 22 which is roughened or left unfinished as explained above so as to have a large area of engagement with the supporting surface. In Fig. 5 there is shown a still further form of projection which is similar to the projection 20 of Fig. 3, and as indicated at 23 is of pyramidal configuration having a sharp pointed end for engagement with the supporting surface.
Referring now to Figs. 6, 7 and 8, there is shown a still further form of the invention. According to this form of the invention there is provided a pitcher 25 having a bottom 26 having a plurality of sockets disposed there on as indicated at 27 with rotatable or adjustable balls 28 disposed respectively for adjustment in the respective socket formations.
Each ball 28 has a half rubber portion 29 with a vacuum cup 31 therein. This rubber portion has a portion 32 dovetailed to the rubber portion 29, as indicated at 33, and which is smooth to permit the easy use of the pitcher 25 when the table surface is steady and motionless. During rough weather upon ships at sea or in airplanes, this ball 28 can be adjusted to the position shown in Fig. 8 from the position shown in Fig. 7, in the manner illustrated by the finger so that the rubber portion 29 and the vacuum cup formation thereof will engage the supporting surface. It will be apparent that upon the supporting surface being inclined the vacuum cup formation and the rubber will hold the pitcher against sliding movement, and thus prevent the pitcher from dropping to the floor from the table during any shifting or departure of the table surface from its usual horizontal position. During calm weather at sea, the ball 28 can be shifted back to the position shown in Fig. 7. The portion 32 having the smooth surface can be made of wood, ivory, ceramic or plastic material. This smooth portion 27 is exposed normally as it offers smoother handling of the chinaware, but in stormy weather aboard ship, the rubber side containing a suction cup is used.
While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.
