DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(9) The preferred embodiment of the present invention is depicted within FIGS. 1 through 6. However, the invention is not limited to what is specifically illustrated and described. 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 also falls with the scope of this invention.

(10) The terms a and an herein do not denote a limitation of quantity, but rather denote the presence of at least one (1) of the referenced items. In addition, unless otherwise denoted all directional signals such as up, down, left, right, inside, outside are taken relative to the illustration shown in FIG. 1.

(11) The present invention describes a laser and string animal toy 10 which provides stimulation and entertainment for a pet 11 such as a cat by provoking active chasing and play via cyclic and iterative motions of a string 30 and a laser beam 61.

(12) Refer now to FIGS. 1, 2, and 3 for environmental views of the laser and string animal toy 10 and which particularly illustrate an articulating string 30 and laser beam 61. The laser and string animal toy 10 has a stand that includes a base assembly 50 and an arm assembly having a stand post 55 and a flexible member 57 which collectively support a housing 60. The housing 60 holds the suspended string 30 and downwardly projects the laser beam 61. The string 30 is suspended from a first actuator assembly 35 that is located within the housing 60 (please reference FIG. 4). The first actuator assembly 35 moves the string 30 which beneficially ends around five to six inches (5-6 in.) above the floor 12 (see FIG. 2) when not moving. The housing 60 also retains a second actuator assembly 63 which, as is explained in more detail subsequently, produces a laser dot 64 on the floor 12.

(13) In use a first motor 37 in the first actuator assembly 35 moves the string 31 around in a circular manner while at the same time jerking it up and down. While this action is happening a second motor 39 in the second actuator assembly 63 moves the laser dot 64 across the floor 12 to gain the attention of the pet 11. The laser dot 64 moves in a controlled fashion about four or five feet (4 or 5 ft.). The laser dot 64 then is turned off. As the pet 11 plays with the string the laser dot 64 turns back on and repeat its motion. As is explained in more detail subsequent the operation of the laser and string animal toy 10 is powered by an internal batter and controlled by control electronics.

(14) Still referring primarily to FIGS. 1, 2, and 3, the base assembly 50 supports the laser and string animal toy 10 in an up-right position using a wide conical shaped base (see, FIG. 5) having a weighted bottom plate 52. The base assembly 50 also houses the electrical power and control equipment which enable operation of the first and second actuator assemblies 35, 63 and which are described in more detail subsequently (see FIG. 6).

(15) The base assembly 50 and vertical stand post 55 are preferably fabricated from a rigid material such as steel, aluminum or plastic while the bottom plate 52 is comprised of any heavy material such as steel. The base assembly 50 rests on the floor 12 and the stand post 55 extends upward from the base assembly 50 approximately two feet (2 ft.). The weight of the bottom plate 52 is at least sufficient to keep the arm assembly (stand post 55 and flexible member 57) upright. The top end of the stand post 55 is permanently fixed to the flexible member 57 via a first connector 58a (FIG. 1).

(16) Still referring to FIGS. 1-3, the flexible member 57 is a gooseneck member that bends to extend horizontally approximately two feet (2 ft.). The housing 60 is attached to the flexible member 57 via a second connector 58a (FIG. 3). The flexible member 57 is envisioned to be made of a compliant and easily bent material such as a wire-wound spring, a soft plastic tube, or the like. The flexible member 57 is thus designed to deflect when the pet 11 pulls on the string 30 and then be restored to its original shape.

(17) FIG. 4 presents a bottom view of the housing 60. As previously noted the housing 60 encloses the first actuator assembly 35 and the second actuator assembly 63. The first actuator 35 includes a variable-speed first electric motor 37 which moves the string 30 using an epicyclic gear train which includes a sun gear 36a and a planet gear 36b. The epicyclic gear train is to be assembled so the planet gear 36b rolls on the inside of the pitch circle of the sun gear 36a, thereby causing the planet gear 36b to travel in a clockwise direction while rotating relative to the sun gear 36a in an anti-clockwise direction. The attached string 30 consequently exhibits a compound motion comprised of both rotating and vertical components to entice and entertain the pet 11.

(18) It should be understood that moving the string 30 may be created using other mechanical devices if desired, such as various arrangements of planetary gears, differently shaped sun gears, a circular disk, as well as an electrical means utilizing at least one (1) motorized device. However, the sun gear 36a and the planet gear 36b provide a beneficial compound motion that pets 11 find interesting.

(19) The rotating planet gear 36b includes an aperture 38 through which an end of the string 30 is inserted and secured by a knot 31 tied in the string 30. The string 30 is removably affixed to the bottom perimeter of the rotating planet gear 36b using the knot 31 to allow for easy replacement of the string 30 as needed.

(20) The second actuator assembly 63 includes a variable-speed second motor 39 which holds a laser source 67 which emits a laser beam 61. The laser beam 61 is reflected downward through a laser window 42 via an adjustable mirror 44 which is mounted to the housing 60. Adjustment of the mirror 44 on its integral axle 46 varies the reflected angle of the laser beam 61. This results in a sweep of the laser dot 64 across the floor 12. In this case the second motor 39 travels in an oscillating bi-directional manner as controlled by motor controlling electronics (see FIGS. 5 and 6 and discussed subsequently). The mirror 44 may also be capable of moving to create a variable circular or ovular pattern across the floor 12 to entertain the pet 11. The produces an effective laser area 62. The laser source 67 is preferably a laser diode that emits a collimated, coherent beam in the visible wavelength spectrum.

(21) Refer now to FIG. 5 for a sectional view of the base assembly 50 taken along section line A-A of FIG. 3. As noted the base assembly 50 provides a stabilizing foundation for the remainder of the laser and string animal toy 10 via a conical base having a bottom weighted plate 52 made of metal or an equivalent material that resists tipping. However, as shown in FIG. 5, the base assembly 50 also includes an enclosing control compartment 80 for electrical and electronic equipment needed to operate the laser and string animal toy 10. The control compartment 80 retains a battery or batteries 82 that are supported on a mount 83; a control module 85, a toggle-type power switch 110, a first speed dial 115a, and a second speed dial 115b (shown together in FIG. 5 because of the angle, but see FIG. 6 for separate dials 115a and 115b). The electrical and electronic equipment within the control compartment 80 are in electrical communication with other devices via interconnecting wiring 65 which in turn pass through the stand post 55 and the flexible member 57. The wiring 65 provides electrical power and control to the first motor 37, the second motor 39, and the laser source 67 in the housing 60 (see FIG. 4). The battery or batteries 82 and other equipment are accessible via a flush-mounted door 150 having a latch 152 and a hinge 154.

(22) The control module 85 provides necessary electrical and electronic components including circuit boards, microprocessors, memory chips, relays, embedded software, and the like. The embedded software within the control module 85 provides various instructions to produce various motion effects of the string 30 and the laser beam 61 to entertain the pet 11 such as, but not limited to: bi-directional motion, speed variations, laser blinking and the like.

(23) As noted the base assembly 50 is equipped with a pair of speed dials 115a, 115b that are externally accessible. The speed dials 115a, 115b enable a user to individually control the speed of each motor 37, 39. It is understood that various additional controls to enable the user to control the motion characteristics of the string 30 and the laser beam 61 may be incorporated into the laser and string animal toy 10, such as buttons, knobs, switches, and the like.

(24) FIG. 6 presents an electrical block diagram of the laser and string animal toy 10. The control module 85 directs electrical power from the battery or batteries 82 to the first motor 37 and to the second motor 39 as well as to the laser source 67 upon closing of the power switch 110. The control module 85 processes control signals from the speed dials 115a, 115b and provides corresponding output current in accordance with software instructions in embedded software within the control module 85 to control the first and second motors 37, 39 via interconnecting wiring 65.

(25) It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and while only one particular configuration is shown and described that is for purposes of clarity and disclosure and not by way of limitation of scope.

(26) 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 laser and string animal toy 10, it would be set in place as indicated in FIG. 1. Using the laser and string animal toy 10 may be performed by: acquiring the laser and string animal toy 10; placing the laser and string animal toy 10 upon a floor 12 in an upright position by allowing the base assembly 50 to support the stand post 55; attaching a string 30 having a desired length to the rotating planet gear 36b of the first actuator 35; placing the power switch 110 OFF state; opening the door 150 of the base 50 using the latch 152; installing the required number of batteries 82 within the control compartment 80; closing the door 150; placing the laser and string animal toy 10 in an area for a pet 11 to play; turning the power switch 110 ON; allowing the string 30 and laser beam 61 to move to provide stimulation and entertainment for the pet 11; adjusting the rotational speeds of the actuator assemblies 35, 63 as desired using the speed dials 115a, 115b; allowing the pet 11 to be stimulated and entertained for a period of time; turning the power switch 110 OFF when it is desired for the pet 11 to stop playing; and benefiting from the stimulation, entertainment and exercise provided the pet 11.
