## Background
FIELD OF THE INVENTION
The present invention is generally related to an animal entertainment device, and more particularly is related to an enclosure with openings that provide the animal access to play items within the enclosure.
BACKGROUND OF THE INVENTION
Animals are naturally inquisitive creatures, often with a natural instinct to chase and play with objects within their environment. Many domestic animals rely on their owners as a source of companionship. However, many owners often have busy daily schedules that restrict the amount of time that an owner can commit to entertaining a pet. Owners often rely on pet toys or animal entertainment devices such as balls or string. The pet toys allow the animal to chase and grab at the toy. To gain the animals attention, the toys often move either under their own power, or by momentum from the pet or owner. For example, a feline may bat at a ball and cause the ball to roll. The movement of the ball further engages the attention of the feline and causes the feline to continue to chase and bat at the ball.
While the ball can captivate an animal for an extended period of time, balls and other play toys often get stuck in a corner or under furniture. The stuck ball loses the attention of the pet and remains in the stuck/hidden position until an owner eventually locates the toy. In addition, the toy or ball often ends up in places that generate hazards to individuals, such as at the bottom of a set of stairs.
Many pet toys have been developed to overcome these associated problems by providing a housing. The housing holds the play objects within the housing. The housing has holes or slits that allow the pet to insert paws and bat at the play object within the housing. The play object bounces around within the object and keeps the attention of the pet while preventing the play object from becoming lost or stuck. While these toys overcome the associated drawbacks of an independent ball or play object, they often cause a pet to become frustrated. After a period of playing with the play objects housed within the enclosure, the pet recognizes that they will never be able to fully grab and the play with the object. This often causes the pet to become unsatisfied and no longer play with the enclosure.
Thus, a heretofore unaddressed need exists in the industry to address the aforementioned deficiencies and inadequacies.
SUMMARY OF THE INVENTION
In one aspect, the invention features an entertainment device for use by animals. The entertainment device has a hollow enclosure with one or more access openings and one or more exit openings. The entertainment device has one or more play items with diameters larger than the access openings and the exit openings within the enclosure. The entertainment device also has one or more smaller play items with diameters larger than the access openings and smaller than the exit openings within the enclosure. The enclosure can also have a maintenance opening with a diameter larger than the play items.
The enclosure may have a weighted base. The weighted base can be a compartment filled with weighted filler material. The one or more exit openings can be located on a surface of the hollow enclosure that requires manipulation of the smaller play item by the animal to remove the smaller play items through the one or more exit openings. The access openings may be large enough for the animal to insert a paw.
In another aspect, the entertainment device has an exterior surface that resembles a mouse or other character. The play item within the enclosure may have an animal attractant housed within the play item. The play items may be spheres that comprise two hemispheres that couple together. The animal attractant can be placed within the two hemispheres prior to coupling the hemispheres together to form the sphere. The entertainment device may also have one or more wires extending from an exterior surface of the hollow enclosure. The one or more wires can wiggle when contact with the enclosure vibrates the wires. The one or more wires extending from the exterior surface of the enclosure may resemble whiskers of a mouse or other small animal. Each of the one or more wires may also have a fabric strip extending from a distal end of the wire.

DETAILED DESCRIPTION
FIG. 1 is a perspective view and FIG. 2 is a side plan view of an animal entertainment device 100, in accordance with the first exemplary embodiment of the invention. The animal entertainment device 100 has a housing 102, one or more internal play items 104, and one or more external play items 106. The housing 102 may include a base 108 and a hollow enclosure 110. The hollow enclosure 110 can have one or more access openings 112 and one or more exit openings 114. The external play items 106 and internal play items 104 initially can be located within the hollow enclosure 110. The animal or pet plays with the play items 104, 106 by inserting their paws through the access openings 112. The pet plays with the play items 104, 106 by making contact with the play items 104, 106 located in the interior of the hollow enclosure 110 and batting the play items 104, 106. The external play items 106 can be removed by the pet from the hollow enclosure 110 by maneuvering the external play item 106 through the exit openings 114. In contrast, the internal play items 104 cannot be removed from the hollow enclosure 110 by the animal.
The hollow enclosure 110 disclosed in the first embodiment of the animal entertainment device 100 has a dome-like shape as shown in FIGS. 1 and 2. The pet is able to crawl on top and around the animal entertainment device 100 in an attempt to get at the play items 104, 106 located in the hollow enclosure 110. The shape of the hollow enclosure 110 of the animal entertainment device 100 is not limited to the dome shape as disclosed in the first exemplary embodiment. A variety of enclosure 110 shapes can be used, for example but not limited to a polygon, sphere, pyramid, or similar shapes as described in later embodiments.
Access openings 112 are located on the surface of the enclosure 110. The access openings 112 are large enough to allow the pet to insert their paws to make contact with the play items 104, 106. The access openings 112 are also small enough to prevent both the internal play items 104 and external play items 106 from passing through the access openings 112. The access openings 112 and enclosure 110 also may serve to partially obstruct the sight of the pet of the play items 104, 106. Many pets, such as felines, are entertained by pawing or batting at a toy that is not within their vision. As the play item 104, 106 moves in and out of the sight of the feline, the feline is intrigued by the play item 104, 106 and further attempts to chase or bat at the play item 104, 106. The access openings 112 can be located on a variety of different locations on the surface of the enclosure 110. The access openings 112 can also have a variety of different shapes and sizes.
One or more exit openings 114 are also located on the surface of the hollow enclosure 110. The exit openings 114 allow the external play items 106 within the enclosure 110 to exit the enclosure 110. This allows the pet to play with the external play items 106 outside of the enclosure 110. The internal play items 104 cannot pass through the exit openings 114 because of their size/shape, requiring the pet to play with the internal play items 104 only through the access openings 112 of the enclosure 110. The combination of internal play items 104 and external play items 106 provides entertainment for the pet while preventing all of the play items 104, 106 from becoming lost.
The one or more exit openings 114 can be located in a variety of positions. The exit openings 114 can be located on the side of the enclosure 110 at the level of the floor of the base 108. Locating the exit openings 114 at this location would allow the external play items 106 to roll out of the enclosure 110. An alternative location of the exit openings 114 can require a greater degree of manipulation of the external play items 104 by the pet in order for the pet to remove the external play item 104 from the enclosure 110. For example, the exit openings 114 can be elevated above the floor of the base 108 on the side of the enclosure 110 or on the top of the enclosure 110. The external play item 106 then would not be able to roll out of the enclosure 110. To remove the external play items 106 the pet would have to lift and push the external play items 106 through the exit openings 114.
The base 108 of the housing 102 may have a surface that directs motion of the play items 104, 106. The floor provided by the base 108 can have a flat surface that allows the play items 104, 106 to roll freely around within the enclosure 110. The floor may also have a shape that facilitates motion of the play items 104, 106 in a specific direction. For example, concentric circles may be used to encourage the play items 104, 106 to roll in circles within the enclosure 110. In another example of the floor, a random undulating pattern can be used to direct the motion of the play items 104, 106 in random directions. The floor can also be designed to direct the play items 104, 106 away from the exit openings 114. This would require the pet to impart momentum on the external play items 106 in a specific direction to cause the external play items 106 to exit the enclosure 110 through the exit openings 114.
FIG. 3 is a bottom plan view of the base 108 of the animal entertainment device 100, in accordance with the first exemplary embodiment of the invention. The base 108 of the housing 102 may be a weighted base 108 to prevent the housing 102 from moving when the pet is playing with the animal entertainment device 100. The weighted base can be accomplished in a variety of ways, for example but not limited to, constructing the base 108 with a heavier material, such as metal, or attaching weights to the bottom of the base 108.
The weighted base 108 can also be accomplished as disclosed in the first embodiment of the animal entertainment device 100. A filler opening 302 allows a filler compartment, internal to the base 108, to be filled with a filler material. A filler cap 304 provides access to the filter compartment. Prior to the pet playing with the animal entertainment device 100, a human flips the animal entertainment device 100 over and removes the filler cap 304. The filler compartment is filled with a filler material through the filler opening 302. The filler material can be a variety of materials, for example, sand, water, kitty litter, or other material. Once the base 108 has an adequate amount of filler material to prevent motion of the housing 102, the filler cap 304 is placed in the filler opening 302. The base 108 is placed on the ground and the device 100 is ready to entertain the pet.
The base 108 can also have a maintenance opening 306. The maintenance opening 306 provides a human access to the hollow enclosure 110 of the housing 102. Using the maintenance opening 306, a human can remove or insert all of the play items 104, 106. The maintenance opening 306 can also be used to clean the interior of the housing 102. A maintenance cap 308 is placed within the maintenance opening 306 to prevent access by the pet or removal of the play items 104, 106. In another example, the construction of the animal entertainment device 100 can provide access to the interior of the enclosure 110 by allowing the enclosure 110 of the housing 102 to detach from the base 108 of the housing 102. The human can remove the enclosure 110 to clean the enclosure 110 interior or add and remove play items 104, 106 from within the housing 102. Snaps, screws or other fasteners can be used to secure the enclosure 110 of the housing 102 to the base 108 of the housing 102.
The housing 102 can be made of a variety of materials, for example but not limited to, plastic, metal, wood, or cardboard. The housing 102 can be constructed by molding the material into the desired shape. The housing 102 can also be constructed by folding or pressing a sheet of material into a desired position. The housing 102 may be made of a variety of different colors and textured surfaces. For example, the enclosure 110 may be made of a translucent plastic to allow the pet to view the play items 104, 106 located within the enclosure 110. The enclosure 110 may also be made with a carpet-like surface, allowing the enclosure 110 to serve as an entertainment device and the exterior of the housing 102 to serve as a scratching surface for the pet.
In accordance with the first embodiment, the animal entertainment device 100 can have two external play items 106 and two internal play items 104. FIG. 4A is a front plan view of an exemplary play item 400 that can be either an internal play item 104 or an external play item 106 of the animal entertainment device 100, in accordance with the first exemplary embodiment of the invention. In accordance with the first embodiment, both the external play items 106 and the internal play items 104 are round balls. The internal play items 104 of the first embodiment have larger diameters than the diameter of the exit openings 114, thus preventing the internal play items 104 from exiting the enclosure 110 through the exit openings 114. The two external play items 106 are balls that have diameters smaller than the exit openings 114, allowing the external play items 106 to pass through the exit openings 114. Neither internal play items 104 nor external play items 106 are small enough to pass through the smaller access openings 112.
The play items 104, 106 are not limited to the balls disclosed in the first exemplary embodiment. The play items 104, 106 can be a variety of shapes. For example, the play items 104, 106 can be oval or can be shaped to resemble a mouse or bird or other cartoonish or natural prey. The play items 104, 106 can be made of a variety of different materials, for example but not limited to, plastic, rubber, or fabric. The play items 104, 106 can also be a variety of colors or can be colored to resemble a cartoonish or natural prey.
The exit openings 114 are not limited to being selective based on the diameter of the play items 104, 106. Other factors can be used as the limiting factors to prevent exit of the internal play items 104. In another embodiment (not depicted in Figures), the internal play items 104 can be spherical balls while the external play items 106 are oval balls. The exit openings 114 can be oval shaped, thus preventing the spherical shaped internal play items 104 from passing through the exit while allowing the oval shaped external play items 106 to pass through the exit openings 114.
The play items 104, 106 are also not limited to passive play toys that require momentum from the pet for motion. The play items 104, 106 can incorporate a vibrating or wobbly motor with a power source within the play item 104, 106 to cause the play item 104, 106 to move under its own power, thus sparking the interest of the pet in chasing the play item 104, 106. The play item 104, 106 may also incorporate magnets that use the motion of external magnets to cause the play item 104, 106 to move and spark the interest of the pet.
Animal attractants may also be incorporated into the play items 104, 106. For example, catnip, food or other animal attractants can be housed within the play item 104, 106 to gain the attention of the pet. FIG. 4B is a front plan view of an opened exemplary play item 402 of the animal entertainment device 100, in accordance with the first embodiment. The play items 104, 106, in accordance with the first embodiment, are made of two hemispheres 404 that snap together using a compression fitting to make a sphere. Prior to snapping the two hemispheres 404 together, an animal attractant can be inserted within the hemispheres 404. Pores in the surface of the play item 104, 106 allow the aroma of the attractant to enter the air space surrounding the play item 104, 106. When the pet plays with the play item 104, 106 causing the play item 104, 106 to roll, the animal attractant is agitated causing a greater concentration of airborne attractant surrounding the play item 104, 106. As the animal attractant becomes dried out and used, the play item 104, 106 can be unsnapped, as shown in FIG. 4B. The animal attractant can be replaced with fresh animal attractant and the two hemispheres 404 can be snapped back together.
