DETAILED DESCRIPTION

In an embodiment, FIG. 1 is an exploded view of a collapsible putting practice guide 100, as further illustrated in FIGS. 2 and 3. Collapsible putting practice guide 100 may be comprised of a forward guide rail or front extrusion arc piece 101 and a base guide rail or base extrusion arc piece 105. Collapsible putting practice guide 100 may be configured in multiple positions, including especially a collapsed position and an extended position. Forward guide rail 101 and base guide rail 105 may be slidably attached by extension arms 104, and may be configured by adjusting the configurations of extension arms 104 and held in place by tightening friction lock knobs 103. Friction lock knobs 103 may have a threaded machine screw attached for engagement with track nut 106. Forward guide rail 101 and base guide rail 105 may have a track 109 and 110, respectively, running substantially the length of the rail. Track nut 106 may be placed in this track during assembly. Track nut 106 may be threaded to correspond with the thread on friction lock knobs 103. Friction lock knobs 103 may be screwed into track nut 106. Track nut 106 may slide the length of groove 109 or 110 such that the extension arms can slide to any desired position on the guide rails. End caps 103 may be coupled to terminal ends of forward guide rail 101 and base guide rail 105 with screws 108. End caps 102 ensure that track nut 106 does not slide out of track 109 or 110. A left foot spacer 107a and a right foot spacer 107b may be coupled to extension arms 104 and base guide rail 105 through engagement with friction lock knobs 103. Left foot spacer 107a and right foot spacer 107b should be able to slide in track 110 such that they can be configured to a desired width.

In an embodiment, the extended position as illustrated by FIG. 2 is utilized during use of the apparatus. The user places his or her feet on or outside the molded plastic, rubber, or metal foot spacers to align themselves with the device. The spacing of the foot spacers can be adjusted by the user depending upon the user's height and/or stance. In the preferred embodiment, the foot spacers are fastened in place by friction lock knobs. However, other methods for fastening the foot spacers in place could be used, such as clamps or interlocking grooves. Furthermore, the apparatus could deliver the desired results without the inclusion of the foot spacers. The foot spacers are slideably attached to a base piece. In the preferred embodiment, the foot spacers are slideably attached to the base piece through a grove that runs substantially through the length of the base piece. In a preferred embodiment the base piece is slightly arced. This promotes the proper putting stance and enhances ergonomic design. The base piece can be made from aluminum, plastic, and the like.

FIG. 3 is an orthographic projection of an embodiment in the collapsed position. The collapsible putting apparatus has two basic positions; however the apparatus can be configured to multiple positions therebetween. The primary position is the extended position, as best illustrated by FIG. 2, and the secondary position is the collapsed position, as illustrated by FIG. 3. The apparatus is configured to the collapsed position when not in use. This allows the apparatus to be easily stored in a compartment of a golf bag. The collapsed position also allows for easy transport of the apparatus.

In an embodiment, the base piece is pivotably attached to two extension arms, although alternate embodiments could incorporate one extension arm or more than two extension arms. In the embodiment, the extension arms have a scissor-pivot and are slotted for distance adjustability. The extension arm comprises two pieces, a slotted piece and a solid piece. The solid piece can be repositioned within the slotted piece. The solid piece and the slotted piece can be locked in place by friction lock knobs. Alternate embodiments could accomplish this adjustable positioning through various means, such as clamps or interlocking grooves.

In the embodiment, as best illustrated by FIG. 2 and FIG. 3, the extension arms are pivotably attached to a front extrusion arc piece. The front extrusion arc piece and the base piece should be of substantially exact measurements to promote the space concerns of the collapsible position, as best illustrated in FIG. 2. The front extrusion arc piece can be made from aluminum, plastic, and the like. The user places a golf ball at a designated portion of the front extrusion arc piece. Then using the front extrusion arc piece as a guide, attempts to duplicate the same putting stroke every time a golf ball is struck.

In an embodiment, the front extrusion arc piece incorporates a groove substantially through the length of the piece. Molded plastic or metal end caps are coupled to the ends of the front extrusion arc piece and the base piece. These end caps cover any rough edges that may be at the ends of either the front extrusion arc piece or the base piece, and prevent the foot spacers from coming unattached from the base piece.

These and further modifications and substitutions made by one of ordinary skill in the art are within the scope of the present invention, which is not limited.
