Description of the Preferred Embodiment
As shown in Figure a golf cup advertising device or assembly 10 is provided. Device 10, which has an axis 11, includes a golf cup or golf cup unit or golf cup subassembly 12, an advertising insert or disc or insert member 14, and connecting means or connectors 16. Disc 14 has an advertisement or lettering 18, which is disposed thereon.
As shown in FIGS. 1 and 2, golf cup unit 12 includes a cylindrical outer wall portion 20, which has an inner ledge portion 22. Cup unit 12 also includes a tubular inner wall portion 24, and a plurality of peripherally spaced ribs or fins or radial walls 26, 28, 30, 32, 34. The fins 26, 28, 30, 32, 34 have a conical upper surface 36, which has an angle 38, that is inclined relative to a horizontal reference line in section view.
As shown in FIGS. 1 and 2, the cylindrical outer wall portion 20 has a length 40 and an outside diameter 42. The dimensions of length 40 and outside diameter 42 are in accordance with the dimensions of a standard golf cup as set by the United States Golf Association (U.S.G.A.).
As shown in FIGS. 1 and 2, tubular portion 24 has an inner surface 44, which has two fluid drainage grooves 46, 48. Tubular portion 24 normally receives a flag handle or pole (not shown). Water, from rain or drainage, which flows into device 10, flows over disc 14 and then flows down through drainage grooves 46, 48, or flows under disc 14 and then flows down between fins 26, 28, 30, 32, 34, or down along the inside of ledge 22.
As shown in FIG. 3, disc 14 has a lower surface 50, which has a disc surface angle 52 relative to a reference horizontal line in section view. Angle 52 is normally slightly smaller than angle 38 of fin surfaces 36 (see FIG. 2), so that, before pressing down on disc 14, a portion of disc surface 50 is resting on ledge 22. After pressing down on disc 14, portions of disc surface 50 contact fin surfaces 36.
Disc 14 also has a radially inner portion 54, which has a circular inner surface 56 defining a central aperture in disc 14. Disc 14 also has a circular outer surface 58.
Connecting means 16 includes a bayonet-type, axial, cup extension 60 (see FIG. 2), which is fixedly connected to tubular portion 24, and a circular flange 62, which is fixedly connected to cup extension 60. Flange 62 has a plurality of peripherally spaced slots 64, 66, 68, 70 (see FIG. 1), which have respective tapered or cam grooves or cam portions 72, 74, 76, 78, that have respective lock grooves or lock recesses 80, 82, 84, 86.
Connecting means also includes a plurality of peripherally spaced disc tangs or prongs 88, 90, 92, 94, which are fixedly connected to disc 14 at its inner surface 56 (see Fig. 1). In FIG. 1, four prongs 88, 90, 92, 94, which are spaced at 90 degrees apart, are shown. Prongs 88, 90, 92, 94, are received in respective slots 64, 66, 68, 70 and cam grooves 72, 74, 76, 78 and lock recesses 80, 82, 84, 86.
In the assembly of disc 14 into cup 12, a downward force, as shown by arrow 96 in Figure 1, is applied to disc 14 adjacent to its inner portion 54. Simultaneously, a torque or twisting moment, as shown by arrow 98 in FIG. 1, is applied to disc 14. This causes disc 14 to deflect or deform, so that disc surface 50 confirms to and contacts fin surfaces 36. This also causes prongs 88, 90, 92, 94 to move through respective slots 64, 66, 68, 70 and then through respective cam grooves 72, 74, 76, 78 to respective lock recesses 80, 82, 84, 86. Disc surface 50, when deflected, has an angle equal to fin surface angle 38. Since disc 14 is deflected, disc 14 has a reaction force so that prongs 88, 90, 92, 94 apply a relatively large normal force and friction force on its respective lock recesses 80, 82, 84, 86. Such friction force minimizes the possibility that disc 14 will be rotated to a position where disc 14 can be pulled up from cup 12, by accident, mistake or other like reason.
Lock recesses 80, 82, 84, 86 have respective shoulder portions 81, 83 as shown in FIG. 1. Shoulder portions 81, 83 help to lock respective prongs 88, 90 into place in recesses 80, 82.
A method of assembly of advertisement insert disc 14 into a golf cup 12 is indicated hereafter. First, position disc 14 inside cup 12, so that an outer part of lower surface 50 of disc 14 rests on an inner ledge portion 22 of cup 12. Second, provide an inner tubular portion 60 which has a flange portion 62 that has at least one slot 64 with a connecting cam groove 72 and a connecting lock recess 80, and which is supported by cup 12. Third, provide a disc inner portion 54, which has a circular inner surface 56, that has at least one prong 88, and which is supported by disc 14. Fourth, apply a downward force 96 on disc portion 54 and simultaneously apply a twisting moment 98 on disc 14, so that disc inner portion 54 deflects downwardly and so that prong 88 is urged into slot 64 and so that prong 88 is urged through cam groove 72 and is urged into lock recess 80.
The advantages of device 10 are indicated hereafter:
A. The problem of a golfer, or other person, sometimes accidentally or mistakenly pulling out the advertisement disc 14 from the golf cup 12 (such as when taking a golf ball or flag out of the hole) is avoided.
B. The means of locking and unlocking the disc 14, such as prongs 88, 90, 92, 94 and lock recesses 80, 82 84, 86, are not readily seen by a person looking into the golf cup 12 whereby easy or accidental removal of the disc is avoided.
While the invention has been described in its preferred embodiment, it is to be understood that the words which have been used are words of description rather than limitation and that changes may be made within the purview of the appended claims without departing from the true scope and spirit of the invention in its broader aspects.
