DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The best mode for carrying out the invention is presented in terms of its preferred embodiment, herein depicted within FIGS. 1 through 9, and 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, and that any such work around will also fall under scope of this invention. It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope.
The terms “a” and “an” herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items.
Referring now to FIG. 1, an environmental view of a portable leash anchor (herein described as the “device”) 10, according to a preferred embodiment of the present invention, is disclosed. The device 10 provides a temporary anchoring means for use with pet leashes 102 to positionally constrain a pet 100 to a structure 105 such as a vehicle, a building, or the like. The device 10 comprises a bottom base portion 22 which comprises a large suction cup assembly 20 along a bottom surface allowing a user to quickly attach the device 10 to any smooth surface 110. The device 10 also comprises an attached quick release clasp 82 onto which a conventional dog leash 102 may be easily attached. The pet 100 and leash 102 may be attached to the device 10 to assure the pet 100 will stay in place until the user returns. Upon return, the leash 102 can be easily disengaged and the device 10 released from said smooth surface 110 by pivoting a vacuum-releasing handle 60.
Referring now to FIGS. 2 and 3, a perspective and a section view of the portable leash anchor 10 taken along section line A-A (see FIG. 4), according to a preferred embodiment of the present invention, are disclosed. The device 10 comprises a circular base 22 and is envisioned being introduced in various sizes of approximately three (3) to six (6) inches in diameter depending on a size of a pet 100. The device 10 further comprises a pivoting handle 60 and a stationary handle 64 both of which extend upwardly being parallel to each other attached along a bisecting centerline of said base 22. The handles 60, 64 are of an arcuate shape having open center areas into which a user may insert their fingers to firmly grasp the device 10. The base 22 and handles 60, 64 are envisioned to be made of rugged metal or composite plastic materials.
The pivoting handle 60 provides a means to both release and produce a vacuum zone 25 within the suction cup assembly 20. The pivoting handle 60 is to be rotatingly anchored at a center portion of the base 22 to a linear clevis link portion 26 via a first pin 30. Said clevis link 26 protrudes downwardly through a washer 40 and through the base 22, in turn being rotatingly connected to an integral attachment feature 28 of the subjacent suction cup 24 via a second pin 32. Said attachment feature 28 is envisioned to be integrally-molded into the suction cup 24 at an upper central location. The first pin 30 connects the clevis link 26 to a cam feature portion 62 of the pivoting handle 60 in an offset manner, such that by motioning said pivoting handle 60 from a horizontal position to a vertical position, the cam feature 62 acts against the washer 40 and resultingly lifts the clevis link 26 and the attachment feature 28 at a center location of the suction cup 24, thereby creating a vacuum zone 25 between said suction cup 24 and the smooth surface 110.
The stationary handle 64 comprises a horseshoe-shaped appendage which protrudes perpendicularly upwardly from the base 22 being parallel to the previously described pivoting handle 60 when rotated to the vertical position. Said stationary handle 64 further comprises a first leg 65a and a second leg 65b which are rigidly affixed to a top surface of said base 22 via integral molding, adhesives, fasteners, or the like. The stationary handle 64 provides a stable means to grasp the device 10 as well as allowing the user to grasp both handles 60, 64 coincidentally to aid in pulling the pivoting handle 60 to the vertical position. The stationary handle 64 further comprises a pair of integrally-molded cylinder-shaped spacers 66 along an upper inner surface which maintain a gap between said pivoting 60 and stationary 64 handles to aid a user when separating said handles 60, 64 to rotate the pivoting handle 60 to the horizontal position. Finally, the first leg portion 65a of the stationary handle 64 comprises a drilled or formed aperture portion 68 through a lower portion of said first leg 65a, thereby providing an attachment means to a common circular metal ring 80 which in turn provides an attachment means to a common spring-loaded clasp 82 onto which a leash 102 may be easily fastened.
Referring now to FIGS. 4 through 9, various views of the device 10 including a top view, a bottom view, a front view, a rear view, a right-side view, and a left side view, respectively, according to a preferred embodiment of the present invention, are disclosed.
It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope.
The preferred embodiment of the present invention can be utilized by the common user in a simple and effortless manner with little or no training. After initial purchase or acquisition of the device 10, it would be installed and utilized as indicated in FIG. 1.
The method of utilizing the device 10 may be achieved by performing the following steps: procuring a model of the device 10 having a diameter base 22 and suction cup 24 which corresponds to a size and strength of the pet 100; attaching the device 10 to a smooth surface 110 of a structure 105 such as a vehicle, building, or the like by rotating the pivoting handle 60 downwardly against the base 22; grasping the stationary handle portion 64 of the device 10 with one's hand; pressing said device 10 against said smooth surface 110; creating a vacuum zone 25 within the suction cup assembly 20 by rotating the pivoting handle 60 upwardly toward the stationary handle 64 until said pivoting handle 60 contacts the spacer portions 66 of said stationary handle 64; releasing the handle portions 60, 64 of the device 10; affixing a pet's 100 leash 102 onto the clasp 82 in a conventional manner; and, benefiting from establishing a suitable and secure connection point for a pet leash 102 at almost any location, afforded a user of the present invention 10.
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 and method of use to the precise forms disclosed. Obviously many modifications and variations are possible in light of the above teaching. The embodiment was chosen and described in order to best explain the principles of the invention and its practical application, and 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. It is understood that various omissions or substitutions of equivalents are contemplated as circumstance may suggest or render expedient, but is intended to cover the application or implementation without departing from the spirit or scope of the claims of the present invention.
