DESCRIPTION OF THE PREFERRED EMBODIMENTS
While the invention is susceptible of various modifications and alternative constructions, certain illustrated embodiments thereof have been shown in the drawings and will be described below in detail. It should be understood, however, that there is no intention to limit the invention to the specific form disclosed, but, on the contrary, the invention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention as defined in the claims.
The present invention is a device for the entertainment of pets and/or the entertainment of owners/third parties present when the present invention is used. The invention, in its simplest form, comprising the attachment of a laser or other light-generating device to an animal through use of a garment. This light-emitting device is for generating a light beam or light pattern upon a surface, preferably in front of the animal. The animal, being inquisitive by nature, will chase or follow said light, thereby entertaining both the animal and the owner/third party.
Referring initially to FIGS. 1A and 1B, shown are two embodiments of the present invention. These embodiments used upon a pet 2 having a head end 4 extending to a tail end 6. The pet used in these illustrations is a dog. However, the device can be put on any animal (cats, birds, etc.). Although the word “pet” is utilized, the present invention is also envisioned as being applicable to all animals, in example, working animals such as police dogs, search and rescue dogs, etc. Such animals are especially included in the utilization of the word “pet.” Such a pet having a head end 4 extending to a tail end 6 and a neck 7.
The presently invented entertainment device 10 is configured for attachment to a garment 12, such as the collar 5 shown. Such a collar extending around the animal's neck 7 in the standard manner. The pet entertainment device 10 for projecting a laser beam 16 onto a surface 3.
Referring now to FIGS. 2 and 3, shown is a third embodiment of the present invention. The pet entertainment device 10 comprising a laser source 14. The preferred laser source 14 comprising a diode laser. While the preferred embodiment of the present invention utilizes a laser, it is envisioned that forms or other light emitting devices, including but not limited to, light emitting diodes, incandescent bulbs, florescent bulbs, and high intensity discharge (HID) bulbs, may be utilized to provide the beam of light necessary for the present invention.
This laser source preferably powered through the use of a battery. The laser source for projecting a laser beam 16 or other light source upon a surface. The surface could be the ground in front of the pet, the wall in front of the pet or another surface. While the laser source could be merely aimed directly in front of the pet, it is preferred the laser device be configured for movement so that the laser beam directed therefrom moves relative to the animal.
The present invention achieves this movement through a laser director 20. This laser director comprising any number of means, including but not limited to, mechanical means, chemical means, resilient means, and electronic means. In the embodiment shown, the laser director 20 comprises a pair of servos, namely a first servo 22 and a second servo 24. These servos are perpendicular to one another. Rotation of the first servo preferably causes movement of the laser source 14 within a generally horizontal plane, whereas movement of the second servo preferably results in a generally vertical movement of the laser source and/or laser beam. Therefore, through movement of the first and second servos, the laser beam can be moved as desired along the surface 3.
In the embodiment shown, the invention utilizes an extension pole or post 30 for elevating the laser source 14 away from laser director and the body of the pet entertainment device. While this is not necessary for the operation of the device, such extension or elevation is utilized to position the laser source 14 above the head of the animal, upon which the device is being worn (as shown in FIG. 1A). While it is envisioned the present invention will extend over the head of the animal, it is just as easily modified to extend otherwise away from the body of the animal so as to achieve same purposes while not being vertically over the head of the animal (as shown in FIG. 1B). In the manner shown in the drawings, rotation of the first servo results in rotation of the extension pole. The extension pole is attached via a spring 40 to the laser source, thereby rotation for servo generally results in a generally horizontal rotation of the laser beam projected by the laser source.
In the preferred embodiment, a pulley 35 extends from the second servo 24, which is rotatably attached to the second servo 24. A cable 37 is connected to the pulley 35 and held in tension with the laser source, preferably at the spring first end 42 (spring second in 44 attaching to the extension pole 30), whereas the spring first end 42 attaches to the laser source 14. Being held in tension with the spring portion and/or the laser source itself by releasing said tension, the laser source will move generally vertically. Whereas by increasing such tension, the laser source will be pulled downward thereby directing the laser beam downward. Preferably an elbow 36 or other suitable means is used for directing the movement of the cable 37 relative to the entertainment device 10. While this is discussed as the preferred manner of moving the “aim” of the laser beam, other means and mechanisms for making such movements are likewise envisioned.
It is preferred that a remote control be utilized for controlling the operation of the pet entertainment device 10. As such, a transmitter would be located (handheld) at a first location, whereas a receiver 62 for such transmissions would be built into the pet entertainment device 10 so that the remote control could control the movement and operability (including power-on and power-off) of the pet entertainment device 10. It is preferred that such a remote control system be operated on a wireless radio frequency. However, other manners of doing so are envisioned, including, but not limited to, infrared, ultrasonic, etc. Although the embodiment uses a remote (wireless) control system, it is expressly envisioned that a wired control system could also be formed.
While there is shown and described the present preferred embodiment of the invention, it is to be distinctly understood that this invention is not limited thereto but may be variously embodied to practice within the scope of the following claims. From the foregoing description, it will be apparent that various changes may be made without departing from the spirit and scope of the invention as defined by the following claims.
