DESCRIPTION OF THE PREFERRED EMBODIMENT

[0026] Referring now to the drawings, a seamless stamp device for impressing configurations into deformable materials that ultimately harden into non-deformable configurations in accordance with the present invention is denoted as numeral 10. The seamless stamp device 10 is fabricated from a myriad of materials including but not limited to polyurethane, relatively hard rubber, and similar relatively rigid, lightweight materials. The seamless stamp device 10 includes a recess member 6 having a substantially planar top wall 12 and an undulating bottom wall 14 with a plurality of ridges 16 integrally joined to the bottom wall 14, the ridges 16 defining a preselected pattern upon the bottom wall 14. The seamless stamp device further includes a protrusion member 8 having a substantially planar top wall 18 and an undulating bottom wall 20 with a plurality of ridges 22 integrally joined to the bottom wall 20, the ridges 22 defining a preselected pattern upon the bottom wall 20.

[0027] Each ridge 16 extending from the bottom wall 14 of the recess member 6 continues upon the bottom wall 14 until intersecting with another ridge 16 or until terminating proximate to a non-linear and irregular configured peripheral edge 24 of the recess member 6. The respective ridge 16 terminating proximate to the peripheral edge 24 is lineally aligned with a substantially rectangular configured recess 26 having a longitudinal dimension of about three inches and a lateral dimension of about one-half inch, and longitudinally extending from an end wall 27 of the respective ridge 16 and perpendicularly extending to a corresponding side 28 of the recess member 6. The preferred number of ridges 16 terminating proximate to each side 28 of the recess member 6 is two, although more recess 26 can be added to each side 28 as required by the user of the device 10.

[0028] Each ridge 22 extending from the bottom wall 20 of the protrusion member 8 continues upon the bottom wall 20 until intersecting with another ridge 22 or until extending past a non-linear irregular configured peripheral edge 30 of the protrusion member 8 to form a substantially rectangular configured protrusion portion 32 having the same configuration as the ridges 22. The protrusion portions 32 include substantially the same lateral dimensions as the recesses 26 in the recess member 6, but the longitudinal dimension of the protrusion portions 32 is about one and one-half inches or about one-half the longitudinal dimension of the recesses 26, thereby allowing substantially about a one and one-half inch overlap of corresponding tapered edge portions 36 and 38 of respective recess and protrusion members 6 and 8. The overlap of the tapered edge portions 36 and 38 prevents a ridge of deformable material from forming when the recess and protrusion members 6 and 8 are adjacently disposed to form the device 10 for configuring the deformable material. The protrusion portions 32 extend substantially perpendicularly from the peripheral edge 30 of the protrusion member 8.

[0029] The preferred number of ridges 22 extending past the peripheral edge 30 for each side 34 of the protrusion portion 32 is two, although more protrusion portions 32 can be added when the number of corresponding recesses 26 in the recess member 6 is greater than two, but irrespective of the number recesses 26 in each side 28 of the recess member 6, the number of protrusion portions 32 extending from a cooperating side 34 of the protrusion member 8 must equal the number of recesses 26 in the side 28 of the recess member 6 that engages the cooperating side 34 of the protrusion member 8. Although the recess member 6 has been described with only recesses 26 and the protrusion member 8 described with only protrusion portions 32, the recess member 6 can have one side 28 with two recesses 26 and an adjacent or opposite side 28 with two protrusion portions 32 extending from the respective side or sides. Correspondingly, the protrusion member 8 can have one side 34 with only protrusion portions 32 and a second side 40 with only recesses 26.

[0030] Irrespective of the number of recesses 26 and cooperating protrusion portions 32 per side 28 and 34 of the respective recess and protrusion member 6 and 8, the configuration and dimensions for each recess 26 must be constant, and the configuration and dimensions for each protrusion portion 32 must be constant. Further, the configuration and dimensions for each protrusion portion 32 must promote the snug, substantially congruent insertion of each protrusion portion 32 on any one of four sides 34 of the protrusion member 8 into a corresponding recess 26 in any one of four sides 28 of the recess member 6, such that a tapered edge portion 36 of the member 6 which extends about the periphery of the recess member 6 to form about a three inch border; and a tapered edge portion 38 of the protrusion member 8 which also extends about the periphery of the member 8 to form about a three inch border, overlap when each recess 26 in a respective side 28 of the recess member 6 snugly receives a protrusion portion 32 extending from a respective side 34 of the protrusion member 8. The overlapping of the tapered edge portions 36 and 38 prevents the forming of a relatively small ridge (not depicted) in a deformable material that would otherwise be formed between engaging peripheral edges 24 and 30 of engaging sides 28 and 34 of adjacently disposed recess and protrusion members 6 and 8 that are positioned such that the edge portions 24 and 30 butt together. To achieve a seamless pattern continuing across the surface of concrete or other deformable material, cooperating tapered edge portions 36 and 38 of recess and protrusion members 6 and 8 are vertically lowered upon and ultimately overlap each other as a pattern is urged into the surface of the concrete, irrespective of the protrusion member 8 being lower upon the recess member 6, or the recess member 6 being lowered upon the protrusion member 8.

[0031] The primary function of the recesses 26 and protrusion portions 32 is to act as a visual aid or sight or a person disposing the recess and protrusion members 6 and 8 upon a deformable material when only the top walls 12 and 18 of the respective recess and protrusion member 6 and 8 is visible to the person. More specifically, the bottom walls 14 and 20 of the respective recess and protrusion member 6 and 8 are unseen (see FIGS. 3 and 4) by a person when urging the ridges 16 and 22 and undulating surfaces of the bottom walls 14 and 20 into the deformable material to form a pattern or artistic figure into the deformable material. The person using the recess and protrusion members 6 and 8 to construct a pattern in the deformable material will usually start with the bottom wall 14 of the recess member 6 disposed upon a preselected starting corner surface or side surface of a deformable material such as concrete that over time will set-up or harden. Next, the user will select one of four possible sides 34 of the protrusion member 8 that will provide a first selected pattern upon the deformable material (see FIGS. 1 and 2).

[0032] Irrespective of the side 34 of the protrusion member 8 selected, the protrusion portions 32 of the side 34 selected will engage and align with a corresponding end wall 27 of the ridges 16 terminating at a lateral end of the adjacent recess 26 of the recess member 6, when the protrusion portions 32 are vertically inserted into cooperating recesses 26, resulting in a continuous pattern without aberrations in the configuration impressed into the deformable material by two separate recess and protrusion members 6 and 8. Without the recess and protrusion portions 26 and 32 to act as an alignment guide for the user, ridge and undulating patterns configured into the deformable material by the recess and protrusion members 6 and 8 would have interruptions or discontinuity imperfections in the patterns formed into the deformable material after the recess and protrusion members 6 and 8 are removed from the deformable material. However, rather than removing both members 6 and 8, the user normally will remove the first positioned member, whereupon, the same recess member 6 will be rotated, then repositioned such that a second side 40 of the recess member 6 is disposed such that the second side 40 engages a different side 34 of the protrusion member 8, resulting in a variation of the pattern impressed upon the deformable material by using only one recess member 6 and one protrusion member 8 and rotating one or both of the members 6 and 8 to constantly vary the pattern upon the deformable material as each member 6 and 8 is lifted from and repositioned upon the deformable material. Referring to FIG. 1, the recess member 6 is disposed adjacent to and separated from the protrusion member 8. Referring to FIG. 5, the recess member 6 has been rotated such that the second side 40 of the recess member 6 is disposed adjacent to and separated from the protrusion member 8. Referring to FIG. 6, the second side 40 of the recess member 6 engages the protrusion member 8 such that the tapered edge portion 38 of the protrusion member 8 overlaps the tapered edge portion 36 of the recess member 6.

[0033] A second function of the recesses 26 and protrusion portions 32 is to secure together and maintain alignment between the recess and protrusion members 6 and 8 upon a deformable material as the undulating bottom walls 14 and 20, and the ridges 16 and 22 integrally joined to the respective bottom walls 14 and 20, are forcibly and concurrently urged to penetrate the surface of a relatively firm deformable material and ultimately insert into the deformable material to form a configuration consistent with the undulating bottom wall 14 and 20, and ridge 16 and 22 patterns of the recess and protrusion members 6 and 8. The preferred number of recess 26 and protrusion portion 32 combinations is two per side, although a fewer or greater number per side can be provided. However, less recess 26 and protrusion portion 32 combinations per side reduces the securing and alignment maintaining features of the detachably joined recess and protrusion members 6 and 8; and more recess and protrusion portion combinations increases the time and costs for the user to align and disposed the members 6 and 8 upon the surface of the deformable material.

[0034] The top and bottom walls 12 and 14 of the recess member 6 and the top and bottom walls 18 and 20 of the protrusion member 8, in a preferred embodiment, are separated a distance of substantially about one quarter to three-eighths of an inch that defines thicker mid-portions 42 and 44 for the recess and protrusion members 6 and 8, respectively. The mid-portions 42 and 44 are slightly tapered from the center of the mid-portions 42 and 44 until integrally joining respective tapered edge portions 36 and 38 of the recess and protrusion members 6 and 8, resulting in a thickness of substantially about one-eighth of an inch. The tapered edge portions 36 and 38 ultimately taper to form the peripheral edges 24 and 30 of the recess and protrusion member 6 and 8, the peripheral edges 24 and 30 being substantially about one thirty-second of an inch, resulting in a small gap between the bottom wall 14 of the recess member 6 and the peripheral edge 24 of the bottom wall 20 of the protrusion member 8 and correspondingly prevents deformable material forming a ridge in the small gap as the recess and protrusion members 6 and 8 are forcibly inserted into the deformable material.

[0035] Alternatively, the top and bottom walls 12 and 14 of the recess member 6, and top and bottom walls 18 and 20 of the protrusion member 8 can be separated greater distances that provide a thicker more rigid members 6 and 8 and consequently a more rigid device 10 when required to forcibly insert the ridges 16 and 22 into a relatively dense deformable material or into a deformable material that has substantially hardened but is still deformable. The distances separating the top and bottom walls 12 and 14, and 18 and 20 of the preferred embodiment can be reduced, but the resulting device 10 would be to flexible when the surface area of the device 10 approaches substantially about sixteen square feet, irrespective of the configuration of the device 10 being square, rectangular, triangular of otherwise. When the device 10 is to thin and flexible, the user has difficulty disposing the device 10 on a predetermined surface portion of the deformable material, resulting in misalignment between the device 10 and the selected surface portion.

[0036] To enable a user of the device 10 to forcibly and vertically insert the recess and protrusion members 6 and 8 into a deformable material such as concrete, then forcibly and vertically elevate the members 6 and 8 from the concrete, a plurality of cylindrical configured hand grips 7 are integrally joined to the top walls 12 and 18 of the members 6 and 8. The number of hand grips 7 correspond to the number of sides of the members 6 and 8, thereby enabling a user to consistently and vertically urge selected portions of the respective member 6 and 8 into and from the concrete to maintain a seamless pattern across the entire surface of the concrete.

[0037] The ridges 16 and 22 are integrally joined to respective bottom walls 14 and 20, and extend a predetermined distance (generally about one-half inch) from the bottom walls 14 and 20 to form predetermined designs or patterns 18 in the deformable material, when the device 10 is disposed upon and forcibly urged (by an individual or machine) into the deformable material, thereby forcing the ridges 16 and 22 into the deformable material until the bottom walls 14 and 20 engage and penetrate the deformable material; whereupon, after removing the device 10 from the deformable material, a mirror image of the recess and protrusion members 6 and 8 designs 18 is formed into the deformable material and becomes permanent after the deformable material sets-up or hardens.

[0038] The seamless stamp device 10 can be used to configure horizontal surfaces (typically concrete driveways or patios) or can be used to configure vertical surfaces such as plaster on walls. Irrespective of the surface or deformable material, one seamless stamp device 10 formed from one recess 6 and one protrusion 8 member can be used to design the entire surface of the deformable material. Further, the device 10 can include recess and protrusion members 6 and 8 that are rectangular configured with relatively long longitudinal dimensions (ten feet for example) and with relatively short lateral dimensions (one foot for example), or with one relatively long recess member 6 and multiple protrusion members 8 that total the same longitudinal dimension as the relatively long recess member 6. The only limitation to the dimensions and configurations for the recess and protrusion members 6 and 8 for configuring a deformable material is the imagination of the fabricator of the device 10.

[0039] To enable the recess and protrusion members 6 and 8 to be cooperatively joined together irrespective of the configurations of the peripheral edges 24 and 30 of the relative sides 28 and 34 of the members 6 and 8, the positioning of each recess 26 and each protrusion portion 32 on each side 28 and 34 must be determined by first identifying the midpoints 46 and 48 for respective sides 28 and 34 of the members 6 and 8, then disposing each recess 26 and each protrusion portion 32 the same distance measured from the respective midpoint 46 and 48 to a centerline 50 for each recess 26, and to a centerline 52 for each protrusion portion 32.

[0040] The constant distance of separation between the recesses 26 and the protrusion portions 32 on respective sides 28 and 34 of the members 6 and 8, allows any side 28 of the recess member 6 to be detachably joined to any side 34 of the protrusion member 8 to form a unique design for each one of a plurality of surfaces for multiple deformable material locations by using only one recess member 6 and one protrusion member 8 to form the device 10. As long as recesses 26 and protrusion portions 32 can be axially aligned when joining a recess member 6 to a protrusion member 8, the devices 10 can have a myriad of configurations and dimensions to form any design into a deformable material. Although only one of each of the recess 6 and protrusion members 8 have been detailed for the device 10, the scope of the present invention can be expanded to include multiple recess members 6 to be used with one protrusion member 8, or one recess member 6 with multiple protrusion members 8, or multiple recess members 6 and multiple protrusion members 8. Further, each recess member 6 and each protrusion member 8 can have a unique design configuration formed upon a respective bottom wall 14 and 20; and each recess member 6 and each protrusion member 8 can have a unique configuration (square, rectangular, triangular, etc.) with a unique set of dimensions.

[0041] In operation, a recess member 6 is disposed upon a surface of a deformable material followed by a protrusion member 8 being disposed on the deformable material such that protrusion portions 32 extending from a selected side 34 of the protrusion member 8 are vertically inserted into cooperating longitudinally longer recesses 26 in a tapered edge portion 36 of the recess member 6. The insertion of the protrusion portions 32 into the longitudinally longer recesses 26 results in an end wall 33 of the protrusion portion 32 engaging an end wall 27 of a cooperating ridge 16 secured to the bottom wall 14 of the recess member 6. Further, the engaged end walls 33 and 27 result in the overlap of the tapered edge portion 38 of the protrusion member 8 upon the tapered edge portion 36 of the recess member 6 to prevent deformable material from being squeezed between peripheral edges 24 and 30 of respective recess and protrusion members 6 and 8, thereby preventing ridges of deformable material from forming that would degrade the design of the configuration impressed into the deformable material by the bottom wall 14 and ridges 16 of the recess member 6, and the bottom wall 20 and ridges 22 of the protrusion member 8.

[0042] The joined recess and protrusion members 6 and 8 disposed upon the deformable material are forcibly urged into the deformable material until respective bottom walls 14 and 20 engage the surface of the deformable material. The protrusion portions 32 of the protrusion member 8 are separated from corresponding recesses 26, whereupon, either the recess member 6 or the protrusion member 8 is elevated from the surface of the deformable material, then replaced upon a new smooth surface of the deformable material such that recesses 26 and protrusion portions 32 from different sides 28 of the recess member 6 and/or the protrusion member 8 are again detachably engaged to form the same or different configuration into the surface of the deformable material. The method is repeated until the joined recess and protrusion members 6 and 8 that form the device 10 have systematically and sequentially been impressed into and removed from the deformable material, until a predetermined design has been formed upon and impressed into the entire surface of the deformable material without any seams or ridges formed upon the deformable material that would degrade the design via peripheral edges 24 and 30 of the recess and protrusion members 6 and 8, and without any seams or ridges formed from the insertion of the protrusion portions 32 of the protrusion member 8 into the recesses 26 of the recess member 6.
