HINGE SHIM AND SHEET THEREOF

Abstract

An improved plastic hinge shim or work piece that allows for quick alignment of a door is claimed. The hinge shim is an elongated tapered hard plastic body wherein each hinge shim has transverse score lines so that segments can be broken off. Additionally, the hinge shims are molded in a sheet of a plurality of shims such that they can be folded to form a thicker hinge shim as required for application. The slots provided for the hinge mounting screws permit the hinge shim(s) to be moved further into the cavity or out toward the hinge pin to provide for finer adjustment. These hinge shims can easily slip into the cavity under the hinge without the need for trimming. Moreover, the slots for the hinge screws are open to an edge to permit the hinge shim to be inserted into the cavity without removing the screws for the hinge plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Referring now to the drawings, like reference numerals designate identical or corresponding features throughout the several views. Further, described herein are certain non-limiting embodiments of a shim and sheet thereof for proper mounting of doors to respective hinges.

[0020] Referring to FIGS. 1-7, shown are multiple embodiments and defined as hinge shim 100, hinge shim 200, and hinge shim 300. Hinge shim 100, hinge shim 200, and hinge shim 300 represent only one variation of several potential embodiments of the disclosed hinge shim. Variations between hinge shims are introduced to the market based on variations of door hinges, as door hinges are introduced to the market. It is contemplated that the number of variety of types of hinge shims within the spirit of the present design is limited only by the number and variety of door hinges which include a bi-planer design that requires mounting to a door jamb, a hinge pin, and door.

[0021] Specifically referring to FIGS. 1 and 2, shown are one potential embodiment of a hinge shim 100. FIG. 2 illustrates the tapered aspect of the hinge shim 100. Shown is a gradually and uniformly, linearly tapered aspect from a thicker section 102 to a thinner section 104. The thinner section 104 may be further defined by the thinness and nearly sharp edge. No discrete boundary between thicker section 102 and thinner section 104 may exist.

[0022] Further illustrated in FIG. 1 are slots 106, open slots 108, and score lines 110. Where any two of the thicker section 102 and thinner section 104 may meet, a score line 110 may be further defined. The score lines 110 may further indicate where a boundary area between two shim 100 may exist. However, a user is free to create an impromptu score line at any point along the width of the shim 100 by using the reference line 111 as a reference point. Thus, the reference line 111 may guide a user of shim 100 to make a more appropriately sized shim 100 for any one individual hinge by guiding a user of shim 100 to cut or fold at any reference line 111 or between any reference line 111. Thus, reference line 111 may be located at any particular location along the width of the hinge shim 100 provided, and to aid in, enabling the hinge shim 100 to accurately align a hinge to a door jamb (not shown).

[0023] Specifically referring to FIGS. 3 and 4, shown are one potential embodiment of a hinge shim 200. FIG. 4 illustrates the tapered aspect of the hinge shim 200. Shown is a gradually and uniformly, linearly tapered aspect from a thicker section 202 to a thinner section 204. The thinner section 204 may be further defined by the thinness and nearly sharp edge. No discrete boundary between thicker section 202 and thinner section 204 may exist.

[0024] Further illustrated in FIG. 4 are slots 206, open slots 208, and score lines 210. Where any two of the thicker section 202 and thinner section 204 may meet, a score line 210 may be further defined. The score lines 210 may further indicate where a boundary area between two shim 200 may exist. However, a user is free to create an impromptu score line at any point along the width of the shim 200 by using the reference line 211 as a reference point. Thus, the reference line 211 may guide a user of shim 200 to make a more appropriately sized shim 200 for any one individual hinge by guiding a user of shim 100 to cut or fold at any reference line 211 or between any reference line 211. Thus, reference line 211 may be located at any particular location along the width of the hinge shim 200 provided, and to aid in, enabling the hinge shim 200 to accurately align a hinge to a door jamb (not shown).

[0025] Specifically referring to FIGS. 5 and 6, shown are one potential embodiment of a hinge shim 300. FIG. 6 illustrates the tapered aspect of the hinge shim 300. Shown is a gradually and uniformly, linearly tapered aspect from a thicker section 302 to a thinner section 304. The thinner section 304 may be further defined by the thinness and nearly sharp edge. No discrete boundary between thicker section 302 and thinner section 304 may exist.

[0026] Further illustrated in FIG. 5 are slots 306, open slots 308, and score lines 310. Where any two of the thicker section 302 and thinner section 304 may meet, a score line 310 may be further defined. The score lines 310 may further indicate where a boundary area between two shim 300 may exist. However, a user is free to create an impromptu score line at any point along the width of the shim 300 by using the reference line 311 as a reference point. Thus, the reference line 311 may guide a user of shim 300 to make a more appropriately sized shim 300 for any one individual hinge by guiding a user of shim 300 to cut or fold at any reference line 311 or between any reference line 311. Thus, reference line 311 may be located at any particular location along the width of the hinge shim 300 provided, and to aid in, enabling the hinge shim 300 to accurately align a hinge to a door jamb (not shown).

[0027] Referring now to FIG. 7, shown is hinge shim 100 in a folded configuration. When folded, shim 100, along with all other shims, form a multilayered shim. The hinge shim 100 is folded along a score line 110. The folding along of score line 110 illustrates fold slot 112. Fold slot 112 may be accessed when a prospective user of an embodiment of a hinge shim as described folds a hinge shim 100, 200, or 300 along a score line 110, 210, or 310. It should be noted that a fold slot 112 as described herein is not limited to hinge shim 100, nor is may it be limited to hinge shim 200 or 300, rather the fold slot 112 is contemplated to operate in the same manner with any patterned designed slots. Moreover, shim 100 need not be folded at score line 110 for the fold slot 112 to be open at one end. The user of shim 100 may alternatively separate the shim 100 at score line 110, resulting in fold slot 112 being open at one end as well. The embodiments indicated as hinge shim 100, hinge shim 200, and hinge shim 300 are not limiting, and the variation of a contemplated hinge shim is limited only by the variations available from door hinges which include a bi-planer design that requires mounting to a door jamb, hinge pin, and door (not shown).

[0028] Having disclosed the structure of the preferred embodiments, it is now possible to describe its function, operation, and use. The present disclosure provides an improved plastic hinge shim or work piece useful in the construction industry. The work pieces are of uniform size and shape, of homogeneous consistency, and of dependable quality, so that they do not change with time. Moreover, they are of such dimensions, hardness, and other characteristics as are especially suited for use as a hinge shim or other work piece and which overcome the disadvantages of other types of shims.

[0029] The slots permit the shim 100, shim 200, or shim 300 to be moved further into the cavity or out toward the hinge's pin to provide a finer adjustment of the door alignment. Each hinge shim has transverse break lines, or score line 110, score line 210, or score line 310 so that segments can be broken off. Additionally, the hinge shims are molded in a sheet of work pieces such that they can be folded to form a thicker hinge shim as required for application. The hinge shims help in quick alignment of the door in the jamb and avoid the requirement of finishing as a result of sanding or planning. When folded into a group of two or three shims, the fold slot 112, open slot 108, and slot 106 may be aligned with each other for ease of inserting the screws. Moreover, when folded or separated, shim 100, shim 200, or shim 300 may cause for slot 106, 206, or 306 to be open to an edge of shim 100, shim 200, or shim 300. When folded or separated, fold slot 112, and in combination with all other slots, may be moved behind a door hinge without removing the screws of the hinges to the door jamb. Shim 100, shim 200, or shim 300 may be separated by pulling or cutting.

[0030] The shim may be molded of plastic material, such as polystyrene, polypropylene or high impact polystyrene, that is hard, durable, of high strength and impact resistance, and of homogeneous consistency. The shim 100, shim 200, or shim 300 may have opposite, flat, rectangular front and back shimming surfaces. Additionally, the shim may be molded as one piece.

[0031] Each shim 100, shim 200, or shim 300 may have transverse breakable means on the thicker and thinner sections and on the opposite surfaces of each work piece. Additionally, the shim 100, shim 200, or shim 300 are molded in a sheet of three shims joined such that they can be folded to form a thicker shim as required for the application. Thus, they can be used as single or as a pair or as three folded together, forming the thickness of shim required for the application.

[0032] The tapered design of the hinge shim 100, shim 200, or shim 300, having thinner and thicker sections may be contemplated to provide additional movement of the door in the jamb for a given thickness. The thinner edges may be adequately described as acuate. Thus, a hinge shim thickness of 0.050 inches at the thick end will displace the hinge pin approximately 0.060 inches. This additional movement may be due to the tapered design of the shim. Additionally, the thinnest section of the shim 100, shim 200, or shim 300 may typically be placed furthest into the cavity under the hinge, thus minimizing the amount of lifting of the hinge at the edge mortised into the door's jamb. This provides a more aesthetically pleasing appearance than a shim of constant thickness, as the shim of constant thickness displaces the edge of the hinge above the surface of the jamb by the amount of the shim thickness.

[0033] The shims may be designed and manufactured, slightly smaller than the hinge itself and may have a rounded corner to the thin edge 104. Moreover, this rounded corner may permit easy insertion under a door hinge by reducing frictional contact or by becoming ensnared during the installation process. Thus, the shim may easily slip into the cavity under the hinge without the need for trimming to fit the cavity based on the elongated shape. Additionally, open slot 108 and fold slot 112 are contemplated for use with the hinge screw and may be open to the thin edge to permit the shim to be inserted into the cavity without removing any hinge screw. Further, upon folding or separating a shim 100, shim 200, or shim 300, slot 106 may then become open to an edge and is represented in this configuration as fold slot 112. Rather, the hinge screws can be loosened one and one half turns and the door moved to open the gap under the hinge and the shim(s) placed into the cavity while leaving the screws in place. Next, the hinge screws are tightened.

[0034] The shim 100, shim 200, or shim 300 as illustrated in FIGS. 1, 3 and 5, are shown as being molded in sets of three but are contemplated to be molded in sets of any number. This set of three can be folded at the score lines 110, score lines 210, or score lines 310 to provide a thicker, multilayered shim. Each shim is approximately 0.050 inches thick at one end that can move the hinge pin approximately 0.060 inches. Thus, three shims folded together are approximately 0.150 inches thick and will move the hinge pin approximately 0.180 inches. This ability to fold the shims into pairs or a set of three allows for variable and quick adjustment for the alignment of the door. Further, fine adjustments of the hinge can be made by placing the shim 100, shim 200, or shim 300 further into the cavity.

[0035] The shims can provide movement of the hinge pin in either direction. Due to the tapered dimensions of the shim, they may be installed either by inserting the thin edge first into the cavity under the hinge or by alternatively inserting the thick edge first. These two options may move the hinge pin in opposite directions. Thus, the thin edge of the shim is inserted first, if the door to jamb gap, which is opposite from the hinge being adjusted, requires reduction. If the gap is too narrow, then the thick edge can be inserted first, thereby moving the hinge pin in the opposite direction and opening the door to jamb gap.

[0036] Particular uses and embodiments of the plastic shim have been disclosed. However, other work pieces, especially tapered ones such as a stake and other items particularly those suited for the building industry, could equally be incorporated by use of the same principles described above. Therefore, although preferred embodiments of the present disclosure have been shown and described, various modifications and substitutions may be made thereto without departing from the spirit and scope of the disclosure. It is not intended that these embodiments illustrate and describe all possible embodiments. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the disclosure.

[0037] Accordingly, it is not intended that the disclosure be limited except by the appended claims. Insofar as the description above and the accompanying drawings disclose any additional subject matter that is not within the scope of the claims below, the disclosures are not dedicated to the public and the right to file one or more applications to claim such additional embodiments are reserved.
