Adjustable Hole Cover

Abstract

An Adjustable Hole Cover. One size of hole cover will accommodate a wide variety of hole diameters, and fit snugly. The device is made from a lightweight, yet durable material. A version having a cap with an internal metal core is also available. The cover costs less than prior plugs by incorporating a durable cap element to which a low-cost stem is attached. The stem is selected from a group of different-sized stems made from a low-cost material, such as wood.

17. A method for plugging s hole in a thick substrate having a top surface, the method comprising the steps of: selecting a first hole having a first diameter; creating a first hole plug for insertion into said first hole, said creating comprising: obtaining a cap element defined by a diameter that is greater than said first diameter, a top surface and an opposing bottom surface; obtaining a first block, said first block selected from a group of two or more blocks, wherein each said block defines a different diameter relative to said other blocks, and all said blocks in said group defining a diameter that is less than the diameter of said cap element. and attaching said first block to said cap element; and inserting said first hole plug into said first hole, whereby said first block is inserted into said first hole and said cap element covers said first hole such that said bottom surface is resting atop said top surface of said substrate.

18. The method of claim 17, wherein said first block of said creating step is made from wood.

19. The method of claim 17, wherein said cap element of said creating step is made from a material chosen from a group of materials that includes vinyl, rubber and plastic.

20. The method of claim 17, wherein said cap element of said creating step further comprises a rigid core element substantially encased within said vinyl, rubber or plastic.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out his invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the generic principles of the present invention have been defined herein specifically to provide an Adjustable Hole Cover.

[0022] The present invention can best be understood by initial consideration of FIG. 5..sup.1 FIG. 5 is an exploded side view of a preferred embodiment of the adjustable hole plug 50 of the present invention. The cap element 52 is intended to be a mass-produced item that has an aperture 62 formed through it. The cap element 52 is intended to be attached to a stem portion 59 by a screw 56 passing through aperture 62 and into the stem portion 59. .sup.1 As used throughout this disclosure, element numbers enclosed in square brackets [ ] indicates that the referenced element is not shown in the instant drawing figure, but rather is displayed elsewhere in another drawing figure.

[0023] What is unique about this design is that the stem portion 59 is cut to fit the diameter of the bore 60 into which the user intends to cover with the cover 50. A block 54 of wood or other durable yet disposable material is cut at line 58 so that the block 54 will fit into the desired bore 60. The remaining portion—stem portion 59 is screwed to the cap element 52 by screw 56. This improvement lowers the overall cost of the hole plug 50 as compared to prior plugs, and further makes it much more versatile. A single cap element 52 can not only be re-used, it can be used and re-used for bores 60 of varying diameters. It is a simple matter of detaching and discarding the stem portion 59, and cutting another portion from off of another block 54, and then attaching the new stem portion 59 to the used cap element 52.

[0024] FIGS. 6A and 6B are cutaway top and side views, respectively, of the hole cover 50 of FIG. 5. This version of the cover 50 has a cap element 52 that is reinforced with a metal inner core 82 within a molded plastic outer shell 80. An aperture 62 is formed through both the shell 80 and the core 82 to accept the screw 56 (or other suitable conventional attaching element) therethrough.

[0025] FIG. 7 is a plurality of side views of the hole cover 50 of FIG. 5 as it can be adaptable to different sizes of bores. As shown in these side-by-side views, a single cap element 52, screw 56 and block 54 can be used to cover a virtually unlimited series of different diameter bores or holes 44. It is a simple matter of cutting the block 54 into the properly-sized stem portion 59.

[0026] As shown in FIG. 8, the hole plug 50 could also be supplied with a group 61 of stems 59A, 59B, 59C, 59D that each define a different diameter. In this way, a single hole plug 50 can be adapted to cover a variety of differently-sized holes 44. As shown here also, the corners on one end of the stems 59A-59D could be cut into a tapered shape so that insertion into the bores 44 is made easier.

[0027] Those skilled in the art will appreciate that various adaptations and modifications of the just-described preferred embodiment can be configured without departing from the scope and spirit of the invention. Therefore, it is to be understood that, within the scope of the appended claims, the invention may be practiced other than as specifically described herein.
