This invention relates to shims used in construction products and, more particularly, to shims having a plurality of through openings.
In building construction, both commercial and residential, a wall may be constructed of block, brick or stone. There is a need to level these materials. One known procedure for leveling is to use a flat, rectangular plastic shim. A problem arises in that the shim forms a void in the grout when setting the block, brick or stone. This interruption of the bond between layers reduces the overall strength of the structure. Another unintended consequence of such a void is the creation of an opening in which wind driven rain can enter the structure. The resultant moisture can create a number of unsafe conditions, such as mold, interior leakage, etc.
A similar situation can occur during grouting in place of metal doors, glass block and windows. The frames are drilled to permit grout to be pumped into place. Since solid shims are typically used, blockages are formed in the frames. These blockages require additional fill holes to be made to allow for completion of the grouting.
The present invention is directed to solving one or more of the problems discussed above in a novel and simple manner.
In accordance with the invention, there is provided a shim having a plurality of bores.
Broadly, there is disclosed herein a shim used to fill in space between articles comprising an elongate one piece body of uniform thickness. The body has a plurality of bores extending therethrough. Spacing between the bores is uniform.
It is a feature of the invention that the body is generally U-shaped.
There is disclosed in accordance with another aspect of the invention a shim adapted to fit in a space between articles to be separated and the space filled with grout. The shim comprises an elongate one piece body of uniform thickness. The body has a plurality of bores extending therethrough. Spacing between the bores is uniform.
It is a feature of the invention that the bores are of uniform size.
It is another feature of the invention that the bores are configured in groups of three equally and longitudinally spaced apart bores and the groups are equally spaced apart. The body may be generally U-shaped having opposite legs connected by a central portion and one of the groups of bores is located in the central portion.
It is additional feature of the invention that the shim is constructed of plastic.
It is still another feature of the invention to provide a plurality of counterbores in the body wherein each of the bores extend through one of the counterbores. The counterbores may comprise elongate counterbores wherein a plurality of the bores extend through the elongate counterbores.
There is disclosed in accordance with another aspect of the invention a shim assembly adapted to fit in a space between articles to be separated and the space filled with grout. The shim assembly comprises a plurality of elongate one piece bodies of a plurality of different thicknesses. Each one piece body is of a uniform thickness. The bodies have a plurality of bores extending therethrough. Spacing between the bores is uniform.
It is a feature of the invention to provide a connector receivable in one of the bores to support the body on an article.
It is yet another feature of the invention to provide a connector receivable in aligned bores of each of the bodies to retain the bodies in alignment.
Further features and advantages of the invention will be readily apparent from the specification and from the drawings.
The present invention relates to a shim assembly adapted for use in building construction and using shim pieces having a plurality of uniformly sized, shaped and spaced bores.

The first shim 12 comprises a one piece body 20. The body 20 comprises opposite legs 22 and 24 connected at one end by a connecting portion 26 so that the body 20 is generally U-shaped. As such, the body 20 is elongate, from a distal end 23 of the leg 22 to a distal end 25 of the other leg 24, and turned, or elongate from the distal ends 23 and 25 to the connecting portion 26 with a void 27 between the legs 22 and 24. A plurality of through openings or bores 28 extend through the body 20. The bores 28 are circular and are of uniform size. The bores 28 are provided in groups of three. Spacing between adjacent bores 28 of each group are substantially equal. Spacing between adjacent groups is such that, if desired, an additional bore could be placed between groups to provide equal spacing between each adjacent bore. As such, there are two groups of three bores 28 in each leg 22 and 24 and one group of three bores 28 in the connecting portion 26. The bores 28 in the one leg 22 are aligned with the bores 28 in the other leg 24.
In an illustrated embodiment of the invention, the body 22 is about 3.5″ in overall length and about 1.5″ wide. The width of each leg 22 and 24 and the connecting portion 26 is about ½″ so that the legs 22 and 24 are spaced apart about ½″ in the void 27. The body 20 has a uniform thickness on the order of 1/16″. The bores 28 are about 3/16″ in diameter, with center-center spacing of about 5/16″
The second shim 14 is substantially identical to the first shim 12. Therefore, it will not be described in detail. The second shim 14 differs from the first shim 12 in having a thickness of about ⅛″. Similarly, the third shim 16 is generally similar to the first shim 12, except that it has a thickness of about ¼″. Additionally, the third shim 16 includes a pair of elongate counterbores 30 in each leg 32 and 34. Each elongate counterbore 30 includes a group of bores 38. Each bore 38 in a connecting portion 36 includes an individual counterbore 40. The counterbores 30 and 40 reduce use of material in the third shim 16 and also provide additional spaces to be filled with grout, as described below.
In accordance with the invention, each of the shims 12, 14 and 16 is of molded plastic construction. The connector 18 comprises a dowel or the like of a size to be frictionally received in any of the openings 28 or 38. As such, the connector 18 can be fit into a bore 28 or 38 of any of the shims 12, 14 or 16 to act as a support. Alternatively, a plurality of shims 12, 14 and/or 16 can be stacked in alignment with one or more of the connectors 18 fitting through aligned bores 28 and 38 to retain the shim assembly 10 in alignment.
In accordance with the invention, the individual shims 12, 14 and 16 can be stacked in any combination to achieve a desired thickness. For example, for a thickness of ⅛″, the second shim 14 can be used by itself, or two of the first shims 12 can be stacked together. ⅜″ thickness is provided by stacking the first shim 12 and the second shim 14. Numerous other combinations are possible, as will be apparent to those skilled in the art. As such, the individual shims 12, 14 and 16 can be provided individually or as an assembly or kit including any number of quantities of each individual size, as will be apparent. Moreover, in accordance with the invention, the shims 12, 14 and 16 could be other shapes, such as rectangular, and of different wall thicknesses.
Use of the shim assembly 10 and/or the individual shims 12, 14 and 16 is described in the following figures.

In accordance with the invention, uniform size holes enable installers to secure shims as needed with a pin or dowel, such as the connector 18, which can extend out from the shims. This pin extension allows for accurate shim height and depth to be achieved along with the ability to be used as a hanger pad, as described above. Uniform holes also offer the opportunity for all users to preassemble shims into specific thicknesses by inserting a pin or dowel, such as the connector 18, through the bores 28 and/or 38, as described and illustrated above. Uniform bores 28 and 38 provide the ability and benefit of using the bores to secure the shims 12, 14 and 16 in place without pre-drilling. By installing shims 12, 14 and/or 16 at various points along a wall of block or brick, the shims allow a leveling string to be inserted through the holes and between the shims to aid in the laying of the brick, and/or block, plum, level and squarely. Finally, the bores 28 and 38 provide a convenient and easy precise snap-off or break-off point to adjust for length.

In the illustrated embodiments of the invention, the bores or through openings are circular. Alternatively, they could have other shapes, such as square, octagon or the like.
Thus, in accordance with the invention, there is provided a shim having a plurality of uniformly spaced bores therethrough.
