## Background
FIELD OF THE INVENTION
The present invention is directed to a device for transporting goods to various locations; to a cart designed to reduce the amount of space required for storing the cart; and more particularity, to a cart designed to carry luggage and other items that require transportation configured to nest with like-constructed carts, thereby reducing the space required to store the carts when not in use.
BACKGROUND OF THE INVENTION
Travel, and its corresponding tourism revenues, provides large economic benefits for many countries around the world. As traveling becomes more accessible and even cheaper for the average person, individuals continue to take trips away from their homes in large numbers. Whether traveling by plane, car, or cruise ship, most travel requires individuals to stay in an establishment that provides housing accommodations. Whether a hotel room, ship cabin, or a rented house, these accommodations allow the traveler to store their clothes and other personal belongings in a secure location while they are exploring their chosen destination.
Upon arriving at his/her destination, a traveler requires checking into the living accommodations. This process requires transporting luggage and other personnel belongings from their car to their room. Typically, the traveler unpacks his/her luggage and other personal belongings from the car and loads the luggage and other personnel belongings onto a luggage cart. Whether the individual traveler performs this procedure or hotel personnel are responsible, utilization of the luggage cart makes transporting such items easier and quicker, and reduces the risk of injury from carrying heavy items.
While luggage carts are a tremendous help in moving luggage and other personnel belongings to a traveler's room, the function of these carts, i.e. transportation of large items, often require them to take up a large amount of space. In addition, because hotels do not want their guests to be waiting in the lobby area, they often utilize a large number of the luggage carts. This is particularly true for large resort areas that have a large amount of guests coming and going at any given time. One of the problems with having a large number of these carts is finding a space large enough to store them. As the luggage carts are stored in a back to back or side to side orientation, the storage area must be big enough to accommodate such storage orientations. Even in hotels that do not require having large numbers of the carts, storage of even two units can require more space than desired.
What is needed in the art is a luggage cart configured to nest with like-constructed carts, thereby reducing the space required to store the carts when not in use.
U.S. Pat. No. 8,733,765 describes an airport cart adapted for carrying carry-on luggage and personal items divested prior to a security check point. The cart is described as including a lower luggage tray or shelf and a pair of vertical supports which extend upward from a rear portion of this tray or a horizontal portion of the cart frame. The cart may have dual handles extending rearward in a spaced-apart manner from the vertical supports, such that the handles are parallel to each other and do not block vertical loading of the luggage tray. The cart includes one, two, or more storage or security screening bins that are fixed to or detachably mounted on the vertical supports or the handles. One or more of the storage bins may be compatible with conventional airport screening bins. The bins are horizontally offset from the luggage tray and each other to facilitate unobstructed 3-D screening of bags and items in the bins.
U.S. Pat. No. 6,860,493 teaches a nestable cart described as having a base or platform supported on caster wheels and sides which taper inwardly from the rear end to the front end of the platform. An upwardly extending handle frame extends upwardly from the rear end of the cart. An open area beneath the platform is designed to receive the front end of a platform of a second cart in order to nest two carts together. A nesting guide formation is provided at one end of the platform to guide two platforms into nesting engagement while lifting the rear wheels of a front cart from the ground during nesting of a rear cart into the front cart. The guide formation may be one or more rotating members such as rollers or guide wheels.
U.S. Pat. No. 6,203,029 teaches a flat bed cart described as having a flat, wheeled platform with a front end and a rear end, and an upwardly extending handle frame extending upwardly from the rear end of the platform. The platform has a forward, fixed deck portion and a rear, liftable deck portion having a forward end hinged to the fixed deck portion for rotation about a first horizontal hinge axis extending transverse to the longitudinal axis of the platform. The rear deck portion is movable between a first position co-planar with the forward deck portion for use in transporting items supported on the platform, and a second, raised position when another cart is nested into the rear end of the platform.
U.S. Pat. No. 2,764,419 teaches a light, rigid cart structure described as being suitable for transporting luggage about in a railway or bus station, the cart structure being designed to facilitate nesting relation between carts of similar construction, whereby a minimum amount of area is required for parking or storing the devices.

DETAILED DESCRIPTION OF THE INVENTION
While the present invention is susceptible of embodiment in various forms, there is shown in the drawings and will hereinafter be described a presently preferred, albeit not limiting, embodiment with the understanding that the present disclosure is to be considered an exemplification of the present invention and is not intended to limit the invention to the specific embodiments illustrated.
As shown in FIGS. 1-10, the disclosed invention is a commercial grade cart for transporting luggage and other personal goods, referred to generally as a luggage cart 10. The luggage cart 10 includes a base or platform 12, a first push/pull handle 14, and a second push/pull handle 16. The platform 12 is carried on a plurality of wheels, a first wheel set 18 and a second wheel set 20. The base or platform 12 is configured to receive and transport a load, such as a load from supporting one or more item, such as luggage, placed thereon. While the present invention is described as a cart for transporting luggage, transportation of luggage is not the only intended use. Other large or small items, such as boxes, clothes, grocery items, tools, or any other item or goods that can fit and remain on the platform 12 may be transported. The platform 12 is also configured to aid in nesting like-shaped luggage carts 10.
The platform 12 contains an upper surface 22, see for example FIGS. 2 and 12, and a lower surface 24, see FIGS. 5 and 6. The platform 12 contains a first end 26, a second opposing end 28, and two opposing sides, 30 and 32, see FIGS. 2, 12 and 13. The first end 26 may be termed as a forward end; the second opposing end 28 may be termed as a rear end. The use of “forward end 26” and “rear end 28” is used primarily for reference purposes and describe the direction in which the luggage cart 10 is travelling. Typically, a luggage cart 10 is pushed so that the forward end 26 is facing the direction in which the luggage cart 10 is travelling. Luggage carts 10 may also be pulled by a user, in which case the reference to forward end and rear end would be reversed with regards to the individual moving the luggage cart 10. A bumper 36 can be placed on the perimeter of the platform 12 to prevent damage to the platform 12, and to prevent the luggage cart 10 from damaging walls or tables when being used to transport luggage or other times. The bumper 36 may be made of a plastic or rubber material, such as a rigid or high impact vinyl, a thermo plastic rubber, a neoprene or natural rubber blend, an extruded rubber, or molded urethane.
The platform 12 is carried on the plurality of wheels 18, 20 so that the platform 12 is raised above a surface and can be moved from one location to another location. The first wheel set 18 may comprise two forward end wheel castors 38A and 38B secured to the bottom surface 24 of the platform 12, see FIG. 3. The second wheel set 20 may comprise two rear end wheel castors 40A and 40B. The two rear end wheel castors 40A and 40B are secured to the bottom surface 24 of the platform 12 towards the rear end 28 and spaced apart from the forward end wheel castors 38A and 38B. The two forward end wheel castors 38A and 38B are preferably swivel castors, but may be rigid casters. The two rear end wheel castors 40A and 40B are preferably rigid castors, but may be swivel castors. While the platform 12 is described as being supported by castor wheels, other wheels or wheel assemblies may be used to move the luggage cart 10 directionally from one position to another. Wheels 42A and 42B of castors 38A and 38B may have a smaller diameter or wheel, or tread width, or both a smaller diameter and a smaller wheel/tread width than wheels 44A and 44B of castor 40A and 40B.
The platform 12 is configured to hold and transport various goods, as well as aid in nesting multiple, like-shaped luggage carts 10. The first or forward end 26 is configured to nest a like-shaped luggage cart 10. The second or rear end 28 is configured to receive and engage at least a portion of a like-shaped luggage cart 10. The luggage cart 10 is configured to comprise a first portion which has a smaller dimension than a second portion. As illustrated in FIG. 12, the width, W1, of the first or forward end 26 is smaller than the width, W2, of the second or rear end 28.
The platform 12 uses a primary transporting surface 46 for receiving and holding various goods, and two additional surfaces, 48 and 50, sized and shaped for holding various goods. Surfaces 48 and 50 are separated by a luggage cart nesting site, illustrated herein as a cut out region 52. The cut out region forms two arm-like extensions, a first arm 54 and a second arm 56. The length, L1, of the cut out region 52 is preferably the same as the longitudinal length, L2, of the primary transporting surface 46. Platform 12 preferably comprises a sloping surface. Preferably, the sloping surface is a downwardly sloping surface from the opposing second end 28, down towards the first end 26. The downwardly sloping surface may include the area below the first arm 54 and second arm 56, down towards the first end 26.
The first push/pull handle 14 and the second push/pull handle 16 are configured to aid in moving the luggage cart 10 from one position to another position, provide additional storage areas, and to aid in nesting multiple, like-shaped luggage carts 10. Push/pull handle 14 comprises a bar 58 having a first end 60 and a second opposing end 62. The first end 60 secures to a portion of the primary transporting surface 46 at point or opening 64. The second opposing end 62 secures to a portion of the first arm 54 at point or opening 66. In this configuration, the bar 58 extends the entire length of the platform 12. A first vertical portion 66 of the bar 58 extends upwardly from the upper surface 22. At bend 68, the vertical portion becomes a generally horizontal portion 70 (with reference to upper surface 22). A second bend 72 provides for the bar 58 to provide a second vertical portion 74. The second vertical portion 74 extends upwardly from the upper surface 22. Preferably, the bar 58 is made of a single unit. However, each of the portions, the first vertical portion 66, the horizontal portion 70, and the second vertical portion 74, may be constructed independently and secured together. Bar 58 is secured to the lower surface 24 through support structure 77 with screws 79A and washers 79B.
Push/pull handle 16 comprises a bar 76 having a first end 78 and a second opposing end 80. The first end 78 secures to a portion of the primary transporting surface 46 at a point or opening 82. The second opposing end 80 secures to a portion of the second arm 56 at a point or opening 84. In this configuration, the bar 76 extends the entire length of the platform 12. A first vertical portion 86 of the bar 76 extends upwardly from the upper surface 22. At bend 88, the vertical portion 86 becomes a generally horizontal portion 90 (with reference to upper surface 22). A second bend 92 provides for the bar 76 to provide a second vertical portion 94. The second vertical portion 94 extends upwardly from the upper surface 22. Preferably, the bar 76 is made of a single unit. However, each of the portions, the first vertical portion 86, the horizontal portion 90, and the second vertical portion 94, may be constructed independently and secured together. Bar 76 is secured to the lower surface 24 through support structure with screws 79A and washers 79B (see FIG. 5).
The first vertical portion 66 of bar 58 and the first vertical portion 86 of bar 76 are orientated to be in a generally parallel arrangement. The second vertical portion 74 of bar 58 and the second vertical portion 94 of bar 76 are orientated to be in a generally parallel arrangement. To aid in nesting, the distance D1 between the second vertical portion 74 of bar 58 and the second vertical portion 94 of bar 76 is larger than the distance D2 between the first vertical portion 66 of bar 58 and the first vertical bar 86 of bar 76. The orientation of the two bars 58 and 76 provides a clearance for nesting of like-shaped luggage carts 10. The distance D2 is also a length that is smaller than the distance D3 between wall 95 and 97. The length of distance D3 also defines the size of opening 52.
Referring to FIG. 11, like shaped luggage carts 10, individually referred to as 10A and 10B, are shown in a nested position. The platform 12 of luggage cart 10B is inserted within the opening 52 of luggage cart 10A and in between the second vertical portions (74, 94) of push/pull bars 14 and 16 of luggage cart 10A. The distance D1 between the second vertical portions (74, 94) of push/pull bars 14 and 16 of luggage cart 10B allows the first vertical portions 66, 86 of luggage cart 10A to fit without hindrance. In the inserted position, the first vertical portions 66, 86 of luggage cart 10B rest against a backstop, a back wall 99 (FIG. 13). Since at least a portion of the platform of luggage cart 10B has a downward sloped surface, when nested, a portion of the platform 12 rests underneath first arm 54 and second arm 56. To further aid in proper nesting, the sides 30 and 32 of platform 12 may contain curved surfaces 100 and 102 (see FIGS. 1 and 2) which contain a stop edge 104, 106. As shown in FIG. 11, first arm 54 and second arm 56 of luggage cart 10A rest against stop edges 104, 106, preventing further movement of luggage cart 10A.
To aid in transporting luggage and other goods, the luggage cart 10 may include additional hang bars. A hang bar 108 connects the first vertical portion 66 of bar 58 and the first vertical portion 86 of bar 76. A second hang bar 110 connects the horizontal portion 70 of bar 58 and the horizontal portion 90 of bar 76. A third hang bar 112 is connected to the second hang bar 110 and extends away therefrom. In addition to providing an area to hold items such as clothes, hang bars may also provide stability. Referring to FIG. 14, the platform 12 may also include a guide member, illustrated herein as wheels 114. Wheels 114 may be used to guide the luggage cart 10 away from obstacles, such as walls. Wheels 114 may also be used to prevent damage from accidental contact to such obstacles. Bars 116 and 118 extending out from the second vertical portions (74, 94) of push/pull bars 14 and 16 and securing to arms 54 and 56 may be used to prevent items stored thereon from falling off during transportation.
