Shims are thin pieces of material used in different construction related activities to fill small gaps or spaces between objects (e.g., between a door jam and a door opening, between a window frame and a window opening). For example, shims can be used for support and/or adjustment of the objects. During use, a shim is positioned between the objects and, depending on the length needed for a particular shim, the shim may need to be cut to a desired length. Current shims require a person to score the shims with a utility knife or other suitable tool at a desired location. After scoring the shim, the person can break (or “snap”) the shim at the desired location such that the shim is of desired length.
Concepts presented herein related to a shim that includes a plurality of snap lines extending along a length and/or width of the shim. These snap lines provide a predetermined location for which to adjust a length and/or width of the shim after the shim has been installed.
In one aspect of the concepts presented herein, the shim includes an elongated body having a first major surface, a second major surface opposite from the first major surface, a width, a length, and a thickness. A plurality of snap lines are positioned on at least the first major surface and extend along the length of the elongated body so as to allow manual adjustment of the width of the elongated body at one of said plurality of snap lines. In another embodiment, the plurality of snap lines are also provided on the second major surface.
In another aspect, a method of installing a shim is provided. The method includes providing a shim having a body defining first and second ends and first and second sides positioned between the first and second ends. The method further includes providing a first plurality of snap lines on the body extending in a first direction and providing a second plurality of snap lines extending in a second direction that is substantially perpendicular to the first direction.
In yet a further aspect, a method of forming a shim is provided. The method includes providing a shim blank having a length and a width. In addition, a plurality of snap lines are formed on the snap blank that extend parallel to the length and the width of the shim blank.
The accompanying drawings are included to provide a further understanding of the concepts presented herein and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the concepts and together with the description serve to explain principles of the concepts. Other embodiments and many of the intended advantages of embodiments will be readily appreciated as they become better understood by reference to the following detailed description. The elements of the drawings are not necessarily to scale relative to each other. Like reference numerals designate corresponding similar parts.
In the following Detailed Description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terminology, such as “top,” “bottom,” “front,” “back,” “leading,” “trailing,” etc., is used with reference to the orientation of the Figure(s) being described. Because components of embodiments can be positioned in a number of different orientations, the directional terminology is used for purposes of illustration and is in no way limiting. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.
Shim 10 is formed of an elongated body having an upper surface 12, an opposed lower surface 14, a first end 16, a second end 18, a first side 20 and a second side 22. At first end 16 of shim 10, a thickness of the shim 10 (as measured between surfaces 12 and 14) is less than a thickness at second end 18 of the shim 10. The thickness of shim 10 gradually increases from first end 16 to second end 18 to form a wedge shape. In one embodiment, first end 16 is inserted between objects until surfaces 12 and 14 are positioned between the objects to provide a desired level of adjustment and/or support. Once positioned, the shim 10 can be manually snapped (i.e., broken) along a particular snap line at a desired length.
It is worth noting that shim 10 can include varying degrees of tapering from first end 16 to second end 18. For example, in one embodiment, a thickness of shim 10 is substantially consistent from first end 16 to second end 18 of shim 10. In another embodiment, thickness at first end 16 and/or second and 18 is adjusted to provide a greater degree of tapering or a lesser degree of tapering, as desired.
With particular reference to major surface 12, the plurality of snap lines 11a include lateral snap lines 24, extending along an entire width of shim 10, as measured between sides 20 and 22, in a direction normal to a length of shim 10, as measured from first end 16 to second end 18. The plurality of snap lines 11a also include longitudinal snap lines 26, extending substantially along the entire length of shim 10, from first end 16 to second end 18, in a direction normal to the width of shim 10, as measured from first side 20 to second side 22. In the embodiment illustrated, the lateral snap lines 24 are substantially perpendicular to the longitudinal snap lines 26.
By way of example, lateral snap line 44 and lateral snap line 46 are adjacent one another and separated by a spacing 48. Spacing 48 can be any distance, as desired. In one embodiment, spacing 48 is in a range of 0.0625 inch to 0.5 inch. In another embodiment, spacing 48 is approximately 0.1875 inch. Snap lines 44 and 46 include a plurality of holes positioned from side 20 to side 22. These holes can be spaced apart as desired in order to facilitate snapping of shim 10 along snap line 44 or 46 so as to adjust the length of shim 10.
By way of further example, longitudinal snap line 50 and longitudinal snap line 52 are adjacent one another and separated by a spacing 54. Spacing 54 can be any distance, as desired. In one embodiment, spacing 54 is in a range of 0.0625 inch to 0.5 inch. In a further embodiment, spacing 54 is approximately 0.1875 inch. Snap lines 50, 52 include a plurality of holes spaced apart from end 16 to end 18. The holes form a weakened portion of shim 10 so as to facilitate snapping of shim 10 along snap line 50 or 52 to adjust a width of shim 10.
In the embodiment illustrated, the plurality of holes forming the snap lines 11a, 11b are shown as being rectangular in shape. Other shapes for the plurality of holes can also be used. For example, the shapes can include, without limitation, squares, circles, ovals, star-shapes, irregular shapes, oblong shapes, etc.
Various configurations of the plurality of snap lines 11a, 11b can be used. For example, a length of the plurality of lateral snap lines 24 (i.e., from side 20 to side 22) can extend along substantially the entire width and/or portions thereof such as less than or equal to 60%, 70%, 80%, 90% of the width of shim 10 or more. Furthermore, a number of the plurality of lateral snap lines 24 can be adjusted to be approximately in a range of 5 snap lines to more than 40 snap lines, the number of snap lines extending along the entire length of shim 10 and/or portions thereof such as less than or equal to 60%, 70%, 80%, 90% of the length of shim 10 or more.
Additionally, a length of the plurality of longitudinal snap lines 26 can extend along an entire length and/or portions thereof such as less than or equal to 60%, 70%, 80%, 90% of the length of shim 10 or more. Moreover, a number of the plurality of longitudinal snap lines 26 can be adjusted to be approximately in a range of 2 snap lines to more than 10 snap lines, the number extending along the entire width of shim 10 and/or portions thereof such as less than or equal to 60%, 70%, 80%, 90% of the width of shim 10 or more. To this end, the plurality of snap lines 11a, 11b can be selectively applied to only a middle portion of shim 10, if desired.
The plurality of snap lines 11a, 11b can be formed from a variety of different methods as desired and discussed below. For example, the plurality of snap lines 11a, 11b may be perforated, drilled, pressed and/or otherwise applied to shim 10 to provide a predetermined pattern on shim 10. In the embodiment illustrated in
With particular reference to
During use, shim 10 can be positioned between two objects. Once shim 10 is positioned as desired, a person can apply force (with the person's hand or other suitable tool) to the shim 10 to snap or break off in a position identified by one of the plurality of snap lines 11a, 11b. In this manner, a knife or other cutting mechanism is not required to adjust a length and/or width of shim 10. Adjustment of the length and/or width can be made by a person applying force so as to break the shim 10 along a snap line (e.g. one of snap lines 42, 44, 50, 52, 60, 62) extending along the width or length of shim 10, without the need for a knife or other cutting mechanism. As a result, adjustment of the length and/or width of shim 10 can be performed in a more time efficient manner.
For example, to adjust the length of shim 10, one end (e.g., first and 16) is positioned between two objects. Once positioned as desired, force is applied to shim 10 (e.g., at second end 18) to snap shim 10 along one of the lateral snap lines 24 (e.g., snap line 44 or 46). To adjust the width of shim 10, one side (e.g., side 20) is positioned between two objects. Once positioned as desired, force is applied to shim 10 (e.g., at second side 22) to snap shim 10 along one of the longitudinal snap lines 26 (e.g., snap line 50 or 52).
In one embodiment, shim 10 is formed of a shim blank, one example of which is illustrated in
