ILLUMINATED BEACH BALLS Filed March 25, 1963 ik k ATTORNEYS.
United States Patent O 3,229,976 ILLUMINATED BEACH BALLS Walter L. Allen, Jr., Oak Park, lll.
(419 W. Elm St., Villa Park, Ill.) Filed Mar. 25, 1963, Ser. No. 267,577 6 Claims. (Cl. 273-58) My invention relates to the variety of large playing balls used `on the beach, on a lawn or in the water. A ball of this type is usually made of pliable plastic material; and in some cases the material is translucent and the interior of the ball illuminated, so that the ball may be attractive and easy to follow or catch when it gets dark. Also, beach balls are usually inflatable in order to hold their shape and bounce on impact with the ground.
In the construction of a ball having the above properties, several factors dealing with the eiiiciency of the ball must be considered, such as means for inating the ball, the manner of installing the lighting element and access to the latter for control, renewal or other attention. With these considerations in mind, it is one object of the present invention to provide a lighting element which is positioned in the central region, whereby to lend the ball uniform illumination on all sides.
A further object is to provide an electric light installation in the ball which extends in a medial course and imparts balance to the ball.
Another object is to employ two battery cells as the current source for the lighting element, such cells being positioned in the central region of the ball with the lighting element in alinement with them, whereby to stabilize the ball against rolling tendencies when it is left in a given place.
A still further object is to `design an internal unit for the ball which contains the complete lighting facility, provides easy access t-o the latter and also contains an inating device for the ball.
An additional object is to design the lighting facility in the form of a unit which may be controlled from the outer side of the ball and easily removed for the replacement of battery cells or other attention.
An important object is to design the lighting and inflating means as a tubular unit suitable for ycentral installation in the ball and endwise sealing to the wall of the same.
A better understanding of the invention may be gained by reference to the `accompanying drawings, in which- FIG. 1 is an elevational View of the ball, broken away to reveal the novel lighting and inflating installation;
FIG. 2 is a magnified section of the said installation;
FIGS. 3 and 4 are respectively, sections on the lines 3-3 and 4-4 of FIG. 2;
FIG. 5 is a duplication of the bottom portion of FIG. 2, with one part removed and another extended; and
FIG. 6 is a perspective view, partly in section, of a lighting installation seen in the center portion of FIG. 2.
Referring specically to the drawing, 10 denotes the wall or casing of the beach ball, segmental lines 10a indicating the conventional method of its assembly. For t-he present purpose, the wall or casing is made of pliable plastic material which is translucent and preferably colored with contrasting or ornamental effects.
For the purpose of the invention the ball 10 is made with circular openings 10b on opposite sides suitable for receiving the novel lighting installation between them. The latter is mainly in the form of a long tube 12 of translucent plastic material and adapted to receive a cap 13 over one of its ends. The outer ends of the tube and cap are flared in the form of circular discs 12a and 13a for sealing .application as external closures for the ball openings ltlb along the areas indicated at 14.
3,229,976 Patented Jan. 18, 1966 ICC The cap 13 and tube 12 are assembled through the agency of an annular `snap-joint 15 seen in the -lower portion of FIG. 2, the material of the joint components having a factor of yieldability for that purpose. When installed as described, the tube 12 occupies a diametrical position in the center of the ball.
The tube 12 is employed as a facility for inating the ball 10. Thus, the cap 13 contains a receptacle 16 which extend-s outwardly with a thin-walled tubular stem 16a normally `rolled up a's shown at 16h in FIG. 2; and the receptacle 16 is tapped in its outer end as indicated at 16C to receive a screw-plug 18 designed to bear against the r-oll 16b as shown, the screw-plug having an external rib 18a as a finger-hold to rotate it. When the ball is to be inflated, the screw-plug is removed and the stem 16a unrolled to the form shown in FIG. 5. When air is blown or pumped into the stem 16a, holes 12b made in the tube 12 serve to pass the air into the ball cavity. The stem 16b is rolled up to hold the air momentarily, while the screw-plug 18 follows as a permanent stopper.
The medial portion of the tube 12 serves as a housing for the holder 20 of two electric battery cells 22 which are arranged in longitudinally-spaced relation. The holder is a long spring metal strip from which clips 20a extend to engage the battery cells as seen in FIG. 4. The holder has a bottom end 2Gb which rests on a partition 12h` in the lower part of the tube 12; andthe bend 2Gb has a terminal 20c which is engaged by the casing of the lower battery cell.
Between the battery cells the holder 20 furnishes a support for the light bulb 23 in the form of a C-shaped bracket 25. The lower arm 25a of the latter is perforated for the threaded passage of the bulb base 23a to an extent engaging the center terminal of the light bulb with the center terminal 22a of the lower battery cell, as Vshown in FIG. 2. The bracket 25 is separated by insulation material from the holder 20, such material being in the form of a block 27 of yieldable plastic material. FIGS. 2 and 5 show that that the block has a medial web 27a which forms the insulating separator for the bracket 25 from the holder 20, the bracket lodging in an undercut receptacle 27h in one side of the block, and the holder passing through a similar receptacle 27e in the other side thereof. The bracket is movable along the holder by the frictional sliding of the block 27 along the same.
As seen in FIG. 2, the upper arm 25h of the bracket 25 has a terminal 25C in 'contact with the casing of the upper battery cell 22. The holder then rises to a point above such battery cell, where it terminates with an inclined blade portion 20c carrying a terminal 20d in a position directly over the center terminal 22b of the upper battery cell.
The outer end of the tube 12 is tapped las indicated at 12d for the insertion of a screw-plug 30 which is of yieldable plastic material and makes a hermetical closure for the tube when screwed down, the outer end of the screwplug having a rib 30a as a finger grip. The screw-plug has an inward stem extension 30h meeting the blade portion 20c. The latter, therefore, serves as a switch to turn the light bulb 23 oif when the s-crew-plug 30 is in the retracted position shown in FIG. 2, or on when the screwplug is advanced.
It will now be apparent that the novel lighting and inflating installation has a number of advantageous features. First, it provides a light bulb in the center of the ball cavity, whereby to cast the light evenly in all directions. Further, the installation is axial in respect to the ball, so that the ball is not thrown out of balance. Further, the two battery cells are grouped in the central region, so that they stabilize the ball by their weight and against tendencies to roll when the ball is left in a given place. Further, all the features of the installation are concentrated in a single column which occupies a minimum of space in the center of the ball. Further, the installation is not only sealed endwise to the walls of the ball, but is also yieldable inherently. Thus, the snap joint 15 is normally at the inner end of a long cavity 13b in the wall of the cap 13, which allows the cap and tube t telescope when the ball receives external impact or pressure in the end regions of the tube installation. In this respect the holes 12b in the sides of the tube pass the compressed air created by the impact or pressure to the general interior of the ball, whereby to distribute the pressure into all parts of the same. The yieldable nature of the tube installation therefore saves injury to internal parts or breakage of the light bulb. Further, switching of the light bulb is controlled from the outside of the ball by simple turning action. Further, access to the interior of the central tube is gained easily by removing theterminal screw plug. In this connection, it is apparent that the assembly of the internal holder, light bulb and battery cells is removable as a unit without deating the ball, for handy access in case the light bulb or a battery cell has to be changed. Further, the battery cells not only hold their place in the holder by virtue of the clips 20a, but the bracket supporting the light bulb is slidable to insure the electrical engagement of the light bulb with the adjacent battery cell. Further, the installation is made water-tight endwise, whereby to keep out water or moisture when the ball rolls over wet ground or into the water. Finally, the installation is of a simple nature, and its parts are suiciently sturdy to withstand such shocks or Vibrations as the ball may encounter when used on a beach or lawn.
