BACKGROUND OF THE INVENTION
1. Field of the Invention
The inventive concept(s) disclosed herein relates generally to an apparatus and method for forming a cart, and more particularly, but not by way of limitation, to an apparatus and method for forming a cart by combining and utilizing dollies and livestock fan cage assemblies, extensions, chutes, and the like.
2. Brief Description of Related Art
In the livestock industry, and in particularly, in the competitive field of livestock breeding and showing, a wide variety of equipment is necessary for proper maintenance and showing of the animals. Breeders and owners show their livestock at various competitions and functions, and usually transport into each location the equipment for showing and maintenance of the animals. Numerous items are used for the livestock competitions and functions, and the equipment is often large and bulky.
During a competition, the needed equipment needs to be unloaded at the event location. This typically requires the breeder to back a trailer or truck up to the location doors and manually unload and transport the equipment into the location. The equipment must be transferred to a specific site for display and maintenance of the livestock during the event. This manual process requires a person to carry the equipment to the event site for the showing and maintenance of the animals during the event. Due to the quantity and size of the equipment, this unloading process usually takes several trips. While unloading, several other breeders and owners are typically waiting their turn to unload their equipment. This manual equipment transfer process presents problems of flow into and out of the event area and causes undesirable delay for the numerous breeders and owners waiting to unload their equipment.
Thus, there is a need for a device to minimize the time and effort required to unload and transport the necessary equipment at livestock shows. Additionally, it is desirable to provide a means to conveniently, quickly and easily transport all the necessary equipment from the truck or trailer and into the event location.
It is not believed that the prior art provides a satisfactory apparatus or means for transporting the necessary equipment for livestock showing and maintenance in various livestock competitions and functions. The equipment typically includes large fan cage assemblies, fans, chutes, feed, grooming supplies, and other various supplies. Although dollies are available to move many items, it is not believed that prior art dollies are available which provide the apparatus and means to simultaneously move the required equipment for livestock showing and maintenance.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
Referring now to the drawings and in particular to FIG. 1, shown therein is a fan cage 100 for displaying and maintaining livestock at competitions and other various functions. The fan cage 100 is typically brought to an event in a disassembled condition via a truck or trailer, transported by hand to a specified location for the showing and maintenance of the livestock, and then reassembled as illustrated in FIG. 1. The livestock can then be tethered to the fan cage 100 for showing and maintenance during the event.
Referring now to FIGS. 1-3, the fan cage 100 generally includes two stall dividers 102. Each stall divider 102 is substantially identical in construction; therefore, only one of the stall dividers 102 will be described in detail with reference to FIG. 2. A stall divider 102 can be used for separation of livestock at an event. The stall divider 102 typically includes two vertical support members 104 and 106. The vertical support members 104 and 106 may be fabricated with top openings 104a and 106a, respectively, as well as bottom openings 104b and 106b, respectively. The stall divider 102 can also include several horizontal members 108 and a mesh covering 110 located between portions of the horizontal members 108 and attached to the vertical support members 104 and 106. The fan cage 100 can function to separate the livestock and to contain bedding and other material at an event location. Although an exemplary embodiment of the inventive concept(s) disclosed herein may include the stall divider 102 as illustrated in FIG. 2, there are many configurations of stall dividers known in the industry, which may be used with the inventive concept(s) disclosed herein.
The fan cage 100 illustrated in FIG. 1 can also include two L bars 112, such as the L bars 112 illustrated in FIG. 3. Each L bar 112 preferably has a first straight member 114 and a second straight member 116 joined together to form a right angled corner 118. The first straight member 114, the second straight member 116, and the right angled corner 118 can include open ends 114a, 116a and 118a, respectively. Although an exemplary embodiment of the present disclosure may include an L bar 112 of FIG. 3, there are other L bars available in the industry which may also be used with the inventive concept(s) disclosed herein.
Referring again to FIG. 1, the fan cage 100 can be assembled by inserting the second straight members 116 of two L bars 112 into the top openings 104a of the stall dividers 102. Furthermore, a first straight member 114 of an L bar 112 can connect to a second straight member 114 of a second L bar 112 by inserting the end of the first straight member 114 into the open end 114a of the opposing second straight member 114 for example. Other ways to connect the first straight member 114 to the second straight member 114 may include telescoping members, or clamps, latch pins, and bolts, for example. The fan cage 100 may also be configured with additional L bars 112 inserted into the top openings 104a of the two stall dividers 102. Furthermore, the fan cage 100 may also include fans 120 (see FIG. 3).
