DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(8) The preferred embodiment of the present invention is depicted in FIGS. 1 through s, and alternately in FIGS. 4 and 5. However, the invention is not limited to the specifically described embodiment. A person skilled in the art will appreciate that many other embodiments of the invention are possible without deviating from the basic concept of the invention. Any such work around will also fall under the scope of this invention.

(9) The terms a and an as used herein do not denote a limitation of quantity, but rather denote the presence of at least one (1) of the referenced items.

(10) The present invention describes an extendable frame 10 that is suitable for one-on-one advertising. As shown in FIG. 1 the extendable frame 10 includes a central opening 40. It is envisioned that the central opening 40 is dimensioned to enable the head of a person to be seen there through, ostensibly while the extendable frame 10 is held by the person that is being seen. The extendable frame 10 as well as the central opening 40 are preferably rectangular. However, it may be appreciated that other geometric shapes could be used. For ease of use and portability the extendable frame 10 is preferably constructed from a lightweight and weatherproof material.

(11) FIG. 1 depicts the extendable frame 10 when in a closed configuration. The extendable frame 10 includes a first frame half 20a and a second frame half 20b. The first frame have 20a and the second frame have 20b are ostensibly identical in shape and size so as to present a mirror image configuration. But it should be appreciated that in some applications either the first frame half 20a or the second frame half 20b can be slightly larger than the other. In the preferred extendable frame 10 the first frame half 20a and the second frame half 20b are generally U-shaped and are capable of being brought together or extended away from each other via a rack and pinion gears 37, 38, 39 (which are described in more detail below). The ends of the U-shapes of the first frame half 20a and second frame half 20 beneficially abut together to form the central opening 40.

(12) Adjacent each end of the U-shape of the first frame half 20a is a first indicia first half 21a Similarly, adjacent each end of the U-shape of the second frame half 20b is a first indicia second half 21b. When the first frame half 20a abuts the second frame half 20b the first indicia first halves 21a and the first indicia second halves 21b form a first word, phrase, or logo. In addition, the bridge of the first frame half 20a includes second indicia 22a while the bridge of the second frame half 20b includes a third indicia 22b. The first indicia halves 21a, 21b, the second indicia 22a, and third indicia 22b can all be related to each other. The indicia 21a, 21b, 22a, 22b can either be adhered, imprinted, embossed, carved, or otherwise permanently affixed to the frame halves 20a, 20b. Such indicia 21a, 21b, 22a, 22b can also be customizable as necessary.

(13) Refer now to FIG. 2 for a rear perspective view of the extendable frame 10. As shown, the backsides of each bridge of the first and second frame halves 20a, 20b have a vertical handle 25. The handles 25 enable a user to grasp the extendable frame 10 and to move the first and second frame halves 20a, 20b together or apart. FIG. 2 also shows track systems 30, 31, 32 when the frame 10 is fully closed.

(14) The track systems 30, 31, 32 are located on the backside ends of the first frame half 20a and second frame half 20b. The first track system 30 is affixed toward the outer perimeter of the first frame half 20a. The second track system 32 is affixed toward the inner perimeter of the second frame half 20b (near the central opening 40). The pinion track system 31 is affixed to both the first frame half 20a and second frame half 20b and is in mechanical communication with the first track system 30 and the second track system 32 via a gap between them.

(15) Refer now to FIG. 3 for an illustration of the track systems 30, 31, 32 in more detail. The first track system 30 includes a first rack gear 37 while the second track system 32 has a second rack gear 39. The pinion track system 31 includes an independently rotatable pinion gear 38. The pinion gear 38 is in mechanical communication with and rides along the first rack gear 37 and the second rack gear 39. Movement of the first half 20a relative to the second half 20b translates into movement of the first track system 30 and its first rack gears 37 relative to the pinion gear 38. This causes the first half 20a to either move towards or away from the second frame half 20b.

(16) FIG. 4 illustrates a pair of inserts 50 that are selectively inserted between the first half 20a and second half 20b. The inserts 50 preferably have the same thickness and width as the first frame half 20a and second frame half 20b. The inserts 50 can be inserted between the first frame half 20a and the second half 20b when the first and second frame halves 20a, 20b are pulled apart.

(17) FIG. 5 more clearly shows an individual insert 50. The inserts 50 may possess attachment features that enable attachment to the first frame half 20a and to the second frame half 20b, such as pegs or dowels that are inserted into apertures. A major benefit of the inserts 50 is that they can cover and protect the first rack gear 37, pinion gear 38, and second rack gear 39 from the environment. Two (2) dowels 51a extend away from first side of an insert 50 into two (2) apertures 51c in the first frame half 20a. Two (2) dowels 51b extend away from the second side of an insert 50 into two (2) apertures 51d in the second frame half 20b.

(18) The foregoing descriptions of specific embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and its practical application, to thereby enable others skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated.
