Modular storage units for uniforms and wearable equipment

FIELD OF THE INVENTION

The present invention relates generally to movable storage cabinets. More particularly, the present invention relates to modular storage units for uniforms and wearable equipment.

BACKGROUND OF THE INVENTION

Those involved in field operational units often possess or require a large amount of uniforms, supplies, and other equipment. Examples of such operational units are athletic teams, construction industries, medical and hospital organizations, military and paramilitary organizations, theatre companies, and marching and concert bands. There is currently a need within these groups for better equipment storage and handling solutions. Specifically, there is a need for a storage system that can be used to effectively store equipment at storage sites and cycle and transport the equipment between the storage sites and areas in which the equipment is used.

As an example, space is always at a premium in schools and athletic facilities. There is rarely enough room allocated for athletic equipment storage. The storage space that is made available for athletic equipment is often located in places that are inconvenient for coaches, equipment managers, and players. These storage areas are often small, cramped, and overflow into areas that are not intended for storage purposes, such as locker rooms, gymnasiums, and coaches' offices. Equipment storage rooms are frequently messy with athletic equipment strewn about the floor. The storage room shelves and bins usually do not have labels or allow the equipment managers to visually inspect or manage the gear. Equipping players at the beginning of the season is usually disorganized and characterized by piles of gear spread out over the storage or locker room for weeks. A storage system would address these problems and make efficient use of the allocated space.

Mobility is also an essential part of the storage of many items. While a permanent storage facility allows for certain efficiencies to be gained by having a central location of the stored items, in many instances some of these items need to be transported to another site quickly, inexpensively, and with minimal planning. For instance, in athletic endeavors, planning and managing the practice, game, and travel logistics of teams is a complicated task and usually not the primary focus of the athletic or activities director, coaches, players, and trainers. Athletic equipment is constantly being moved through a usage cycle between “off-season” storage and “in-season” use and management. During the season, equipment constantly needs to be moved to and from storage areas, practice fields, and game sites.

Safety is also a very important aspect of equipment management. Player safety and avoidance of program and personal liability can be accomplished by effectively managing gear through regular inspections and record keeping. Regular gear inventory and inspection is critical to identify and replace expired, damaged, and lost equipment. By taking care of their equipment and knowing what equipment is on hand and “game ready,” schools can also extend equipment life and can assure purchases only as necessary. Safety also encompasses the sanitary aspects of storage. With adequate ventilation, well-designed storage can mitigate the growth and spread of mold and odor associated with locker rooms. Also, by effectively managing and organizing equipment, schools can prevent and control loss and theft.

Moreover, in the field of athletics, equipment storage systems must reflect the pride, excellence, and the winning attitude of the schools' athletic programs. Pride and excellence are rarely reflected in current equipment management areas or processes. Messy, disorganized equipment areas do not reflect discipline, pride, or excellence. Disorganized equipment distribution to players does not support the desired tone of the program. If the storage areas are poorly kept, they do not reflect well on a school's excellence to parents, alumni, fellow educators, and recruits. The makeshift storage areas are usually in a state of disarray and a source of embarrassment for the schools. As a result, the areas are often shut or closed during recruiting trips to prevent further embarrassment.

There are not any commercially available organizational systems meeting the current needs discussed above. As an illustration, high schools, colleges, and universities usually use storage systems ranging from makeshift and make-do systems to generic, mass-marketed products modified for use as athletic equipment storage systems. The makeshift or make-do solutions often comprise homemade wooden shelves or generic shelving available from local hardware stores. Carts are also often homemade and storage containers are usually corrugated boxes, gear bags, garbage bags, laundry hampers, or generic plastic bins. Any labeling is usually done with a marker and tape on the equipment, shelves, and boxes.

Some universities/colleges and professional sports organizations currently use expensive, high-density storage solutions such as those manufactured by Spacesaver Corporation. Because these systems are fixed on dual tracks, those using the system are not allowed to bring the storage to an off-site area. Those wishing to access the storage must come to the storage and cannot bring the storage with them. In addition, solid panels enclose the bins, which inhibits any airflow within the arrangement. Moreover, the bin and shelving arrangement within the systems are also fixed so those using the systems do not have the flexibility of being able to arrange the bins in appropriate dimensions.

Stationary drying racks for uniforms and wearable equipment have been developed. For example, U.S. Pat. Nos. 6,073,783 and 5,685,440 disclose drying racks that could be used for drying uniforms and wearable equipment, but the drying racks are not part of a modular storage system. U.S. Design Pat. Nos. 398,469 and 394,926 depict racks that could be used for drying uniforms and wearable equipment. Some design patents describe or depict wire-framed storage units that could be used to store uniforms or wearable equipment. Some examples are U.S. Pat. No. 6,752,278 and U.S. Design Pat. Nos. 476,183, 429,094, and 392,496. However, these units are not modular and therefore could not be used to transport uniforms or wearable equipment.

Modular storage units having a wire frame have also been developed. For example, U.S. Pat. No. 3,801,176 describes a dual track system in which the modules are movable along tracks within a storage site, the modules being made of wire steel. U.S. Pat. Nos. 6,241,106, 4,941,578, and 4,807,765 describe systems having no sides, but rather only shelves. These carts are not designed to accommodate equipment that is used by field operational units.

What is needed is a better equipment storage and handling solutions for field operational units. Specifically, there is a need for a storage system that can be used to effectively store equipment at storage sites and cycle and transport the equipment between the storage sites and areas in which the equipment is used. There is a need for a storage system having generally reconfigurable storage units that allow sufficient air movement so that uniforms and wearable equipment can be dried when the units are populated with gear.

SUMMARY OF THE INVENTION

In an embodiment of the present invention, a modular storage system for uniforms and wearable equipment includes a plurality of carts. The carts include a base that has a generally rectangular platform having opposed ends and opposed sides with end panels that are operably attached to and extend upward from the opposed ends, the end panels and the platform generally defining a storage space for contents that is accessible through one of the sides. The carts further include wheel assemblies operably attached to and extending below the base to provide a rolling surface adapted to roll on the floor. The carts also include at least one track follower mechanism that is operably attached to one end of the base. The modular storage system further includes a track that is operably positioned on the floor, such that the at least one track follower is selectively engageable with the track, so that the plurality of carts are stored in a generally abutting side-by-side position and the storage space of a selected cart is selectively accessed by moving at least one of the plurality of carts so as to create a space in a direction parallel to the track between the selected cart and at least one adjacent cart such that the storage space of the selected cart is accessible from one of the sides. While the carts provide an enclosed space in which to store uniforms and wearable equipment, the end panels have a plurality of apertures therein to allow for air movement in the storage space to allow contents positioned in the storage space to dry when the plurality of carts are in the abutting side-by-side position sufficient.

In an embodiment of the present invention, the apertures in the modular storage unit represent at least at least 25% of the surface area defined by a perimeter of each end panel. In another embodiment of the present invention, the end panels in the modular storage unit are made of wire-grille that is operably attached to a tubular frame structure. In another embodiment of the present invention, the modular storage unit includes a fan.

In one embodiment of the present invention, the contents in the modular storage unit are selected from the group consisting of: uniforms, wearable equipment, field gear, or any combination thereof.

In an embodiment of the present invention, the modular storage unit includes a top panel that is disposed between and that is generally on top of the end panels that define a top surface of the storage space. In another embodiment of the present invention, the modular storage unit further comprises a secondary storage structure that is carried by and above the top panel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As depicted in FIGS. 1-3, a modular storage system 110 according to an embodiment of the present invention generally comprises a track 114 and a plurality of carts 112, 212. In a preferred embodiment, the carts 112 are arranged in a storage facility along a single track 114. The storage facility can be a retrofitted area of an already existing facility or the storage facility can be designed and implemented into a newly constructed facility. In an already existing facility, the track 114 is preferably positioned onto and connected to a pre-selected portion of a floor. In a newly constructed facility, the track 114 is preferably integrated directly into or onto a newly formed floor.

The modular storage system as depicted in FIG. 1 includes a mixture of retained carts 112 (as shown in FIG. 3) and modular carts 212 (as shown in FIG. 55). As can be seen in FIG. 3, the retained carts 112 populated with uniforms and equipment are preferably movable by manual force in a direction that is generally parallel to and along the track 114. The modular carts 212 as depicted in FIG. 55 are also preferably movable along the track 114. In addition to being movable along the track 114, the modular carts 212 can also be removed from the storage site 111 and taken to an off-site location.

It will be understood that the mixture of retained carts 112 and modular carts 212 can be of any number and mix, depending upon the length of the track 114 installed at the storage facility and the width of each cart 112, 212. It will also be appreciated that any number of tracks 114 could be installed in a variety of floor plan configurations at a given storage facility given the dimensions of the floor plan of the storage facility. As shown in FIG. 1, some of the retained carts 112 are full width (112a) and others are half width (112b). Preferably, all of the carts 112, 212 have a similar length, although this is not required. For purposes of describing the preferred embodiments of the present invention, the carts 112, 212 will be referred to as having a width in a direction generally parallel to the track 114 and a length in a direction generally perpendicular to the track 114. Similarly, the carts 112, 212 will have sides oriented along the length of the carts and end oriented along the width of the carts.

The carts 112, 212 generally comprise a reconfigurable storage structure that includes a number of different means for storing uniforms, equipment, and other items used by field operational units. The modular storage system 110 as depicted in the figures is designed to accommodate high school athletic equipment. As such, the following description of different means for storing uniforms, equipment, and other items is generally directed to athletic equipment storage. However, those of ordinary skill in the art will appreciate that the storage structures and means could be easily used to accommodate a number of different operational units, including, but not limited to, construction industries, medical and hospital organizations, military and paramilitary organizations, theatre companies, and marching and concert bands.

In addition, the arrangement of the track 114 and carts 112. 212 allow users to come to the storage facility, quickly find their equipment in a particular cart, move the carts along the track to access the appropriate cart, remove their equipment from the cart, and move on to an off-storage-site location with the necessary equipment. Because the uniforms and equipment are organized and arranged within the carts, those persons who monitor and track the equipment to be stored in the modular storage system 110 are able to determine what equipment remains within the storage facility and what equipment is being used at an offsite location. When users return to the storage facility to return their uniforms or equipment, they can give the uniforms and equipment to the persons responsible for monitoring and tracking the equipment, who can then return the equipment to the proper cart within the storage facility. Alternatively, users can return their own equipment to the proper cart within the storage facility.

Because the modular carts 212 can be taken out of the confines of the storage facility and transported to an off-site location, the modular storage system 110 of the present invention permits operational units that require large amounts of uniforms and various pieces of equipment to transport the uniforms and equipment in an organized manner. By doing so, the units are much less likely to forget or lose track of the uniforms and equipment. For example, military units often travel with large amounts of gear including uniforms, weapons, first aid kits, tents, cots, ammunition, and other equipment. When the military unit must travel, the logistics of transporting the members and equipment can create pose significant logistical problems. However, by using a modular storage system 110 according to the various embodiments of the present invention, the military unit can travel in an organized manner. Each uniform and piece of equipment can have a position within the carts 112, 212 when leaving a storage facility and when arriving at a destination. Because the equipment does not need to be removed from the cart during transportation, much time and effort can be saved by not having to load and unload any containers.

Also, when inventory is taken prior to leaving a storage facility, inventorying is not required when arriving at a destination as there is no need to remove anything from the cart. These same benefits occur with other operational units such as athletic teams, construction industries, medical and hospital organizations, theatre companies, marching and concert bands, police and fire departments, and medical rescue teams.

Description of the Retained Carts

Referring to FIGS. 3-12, embodiments of the retained cart will be described. It will be noted that reference numerals in the 100's are generally used to denote the base features and components of the retained carts 112. The retained carts 112 are preferably retained within the storage facility during normal use and not designed to be removable from the storage facility. In order to be removed from the storage facility, the retained carts 112 generally would need to be lifted out of the track 114 by selectively releasing them from the confines of the track 114 and then carried out of the storage facility (i.e., to a location other than the location of the track 114). Alternatively, the track 114 may be removed in order to permit the retained carts 114 to be removed from the storage facility.

As depicted in FIG. 4, a retained cart 112 according to an embodiment of the present invention preferably comprises a cart base 116, a cart top 122, a front end 118, and a rear end 120 opposed the front end 18. The cart base 116, cart top 122, front end 118, and rear end 120 generally define a reconfigurable storage structure. The front end 118, rear end 120, and cart top 122 preferably have substantially similar structure on both the retained cart 112 and modular cart 212. As such, the discussion of the front end 118, rear end 120, and cart top 122 with respect to the retained cart 112 is therefore relevant and incorporated by reference to the later discussion with respect to the modular cart 212. For purposes of this description, front is used to reference the end of the cart base that, when in position on the track 114, is closest to the track 114. Rear is used to reference the end of the cart base 116 that is furthest from the track 114.

The cart base 116 of the retained cart 112 according to an embodiment of the present invention, as depicted in FIGS. 5-8, preferably comprises a bottom 124, a pair of opposed base sides 130a, 130b connected to the bottom 124, a front plate 126, and an opposed rear plate 128. The front plate 126 and rear plate 128 are operably connected to a bottom front 132 and a bottom rear 134, respectively, wherein the bottom front 132 and bottom rear 134 are preferably substantially perpendicular to the opposed sides 130a, 130b. As can be seen in FIG. 2, the bottom 124, front plate 126, rear plate 128, and base sides 130a, 130b generally define a storage basement 117 that can be used to store various equipment or articles below a horizontal level of a top surface of base sides 130a, 130b. The bottom 124, front plate 126, rear plate 128, and base sides 130a, 130b are preferably constructed of sheet steel, although other materials such as aluminum, alloys, graphite or composites materials or various plastics could be used without departing from the spirit and scope of the invention.

The cart base 116 further preferably comprises a plurality of preferably cylindrical frame posts 168a, 168b, 168c, 168d disposed on the base sides 130a, 130b where the base sides 130a, 130b intersect the front plate 126 and rear plate 128.

The components of the above-described cart base 116 are preferably selected, configured, and assembled so that the base 116 has a structural integrity and strength sufficient so that when the carts 112 are moved along the track 114, the carts 112 will not canter, flex, or bend by more than 5 degrees from normal to the track 114, and preferably by no more than 2-3 degrees from normal. By having such a structural integrity, when the carts 112 are moved along the track 114, the cart will not bind on the track 114, thus allowing easy manual movement of the carts 112 along the preferred embodiment of a single track 114. As a result of this preferred structural integrity, the present invention is able to dispense with the need for dual track arrangements as is generally taught in the modular storage systems of the prior art.

With continuing reference to FIG. 6, the cart base 116 preferably comprises at least three wheel mechanisms 172. The wheel mechanisms 172 on the retained cart 112 are generally axle-type wheels and generally comprise a wheel 174 having a wheel aperture 176, an axle pin 178 extending through the wheel aperture 176, and a plurality of washers 180. To connect each wheel 174 to the cart base 116, prior to placing the wheel covers 148 onto the cart base 116, the axle pin 178 is first inserted through the axle pin aperture 152 in the wheel cover 148. The axle pin 178 is then preferably inserted through a washer 180, the wheel aperture 176, through more washers 180, and then through the axle pin aperture 158 in the axle plate 150. The axle pin 178 is then connected to the wheel cover 148 by inserting a fastener 800 through a portion of the axle pin 178 into the wheel cover 148. The axle pins 178 and washers 180 are preferably constructed of steel, although other materials such as aluminum, alloys or graphite or composite materials could be used without departing from the spirit and scope of the invention. When the wheel mechanisms 172 are installed on the cart base 116, at least a portion of the wheels 174 extends below the underside 138 of the bottom 124. The wheels 174 are preferably constructed of nylon or polyolefin, such as part number PB0820112WS02 from Tricker Caster & Wheel Sales in Fairbault, Minn., although other equivalent polymer materials could be used without departing from the spirit and scope of the invention. In a preferred embodiment, a total of four wheel mechanisms 172 are utilized, with one pair of wheel mechanisms 172 on each end of the cart base 116. It will be understood that any number of wheel mechanism 172 greater than two could be incorporated into the design of the cart base 116 to decrease the weight load per wheel mechanism 172, for example, by providing additional wheel mechanisms 172 positioned at different points along the length of the cart base 116. In another embodiment of the present invention, the wheel 174 could be a caster wheel or ball wheel.

The cart base 116 further comprises at least one track follower mechanism 182. The track follower mechanism 182 can be seen in FIG. 5 and in greater detail in FIGS. 42-46. As depicted in the figures, the retained cart 112 according to an embodiment of the present invention includes two track follower mechanisms 182 positioned at opposite sides of the front end 118, although it is contemplated that the carts 112 could include one or more track follower mechanisms 182 positioned to engage the track 114 wherever the track 114 is positioned relative to the length of the carts 112, 212. For example, in an alternate embodiment, the track 114 and corresponding track follower mechanisms 182 could be positioned proximate the rear end 120 of the carts 112 or the track followers 182 could be positioned at any position along the length of the cart 112, for example, in the middle of the length of the cart 112. It will be understood, however, that the advantage of the positioning of the track follower mechanisms 182 on the front end of the carts 112 permits for easy following of a single track with the ability to manually move the carts 112 with a minimum amount of effort.

The track follower mechanism 182 comprises a track follower 184 having a plunger 186 that is preferably cylindrical in shape and a roller 192 connected to the plunger 186 using a shoulder bolt 194. The frame posts 168a, 168b, 168c, 168d preferably include a plunger guide 190, such that when the track follower mechanism 182 is inserted into the frame post 168, the plunger 186 of the track follower mechanism 182 rests within the plunger guide 190. Once the plunger 186 rests within the plunger guide 190, the roller 192 can be connected to the plunger 186 using the shoulder bolt 194. In this position, the track follower mechanism 182 is vertically movable and rotatable about the plunger 186 within the frame post 168 in the plunger guide 190. When the track follower mechanism 182 is inserted into the frame posts 168a, 168d, the track follower roller 192 extends below the frame posts 168a, 168d. A plunger cap 188 on the plunger 186 opposite the shoulder bolt 194 prevents the track follower mechanism 182 from falling out of the frame post 168. The roller 192 is preferably constructed of glass-filled nylon, although other materials such as steel, aluminum, bronze, alloys, graphite or composite materials or various plastics could be used without departing from the spirit and scope of the invention. The plunger 186, shoulder bolt 194, and plunger guide 190 are preferably constructed of steel or aluminum, although other materials could be used without departing from the spirit and scope of the invention.

The cart base 116 further preferably includes a plurality of bumpers 196. As depicted in FIGS. 8-12, the bumpers 196 are preferably cylindrical or donut-shaped and preferably comprise a bumper clearance aperture 198 and a bumper flat surface 199. The bumpers 196 are placed onto the frame posts 168a, 168b, 168c, 168d so that the bumper clearance apertures 198 are substantially aligned with post clearance apertures 170 that are included on the frame posts 168a, 168b, 168c, 168d. In this position the bumper flat surfaces 199 on the bumpers 196 proximate the rear plate 128 substantially face one another and the bumper flat surfaces 199 on the bumpers 196 proximate the front plate 126 substantially face one another. This flat surface 199 extends laterally beyond vertical members 304 of frames 302 to provide clearance for any panels that are placed onto the carts 112. The bumpers 196 are preferably constructed of nylon, although other materials such as rubber or various plastics could be used without departing from the spirit and scope of the invention.

The bumpers 196 protect adjacent carts 112, 212 when the carts 112, 212 are moved along the track 114 within the storage facility. If a first cart 112 is moved towards a second cart 112, such that the carts 112 contact one another, the bumpers 196 on the first cart 112 will contact the bumpers 196 of a second cart 112 rather than other parts of the carts 112 coming into contact with one another. As the bumpers 196 are constructed of nylon or other similar resilient materials, they will absorb the forces exerted when adjacent carts 112 are moved into an abutting relation along the track 114.

The cart as depicted in FIG. 4 also preferably comprises a front end 118 and a rear end 120, each end 118, 120 preferably comprising a frame 302 and a wire-grille panel 300 connected to the frame 302 using a plurality of brackets 310.

Wheels 274 according to this embodiment are preferably constructed of urethane, although other materials such as nylon or other similar polymer materials could be used without departing from the spirit and scope of this invention. In another embodiment of the present invention, the wheel 274 could be an axled wheel or ball wheel. The wheel mechanisms 227 are preferably 6″ to 9″ high, optimally 7.5″ high, and the wheels 274 preferably have a diameter of approximately 4″ to 8″, optimally 6.0″ and a width of approximately 1.5″ to 3″, optimally 2.0″. The wheels 274 each have a load rating of at least 500-100 pounds, optimally 850 pounds. As can be seen in FIG. 50a, the wheels 274 preferably comprise a concave cross-section in which the diameter at the center of the wheel is slightly larger than the diameter at the edges of the width of the wheel.

The cart base 216 also preferably comprises a plurality of track follower mechanisms 282. The track follower mechanisms 282 are substantially the same as the track follower mechanisms 182 described above. However, track follower mechanisms 282 further comprise a locking mechanism 293 as depicted in FIGS. 51-54. The locking mechanism 293 allows a user to lock the track follower 284 up in a retained position when the modular cart 212 is removed from the track 114 in the storage facility. As depicted in FIGS. 51-54, the locking mechanism 293 preferably comprises a lever arrangement with a plunger clip 295 and a backer 297, both the plunger clip 295 and backer 297 preferably being L-shaped, the plunger clip 295 and backer 297 being connected to the underside 238 using fasteners 800. The plunger clip 295 and backer 297 are preferably constructed of steel, although other materials such as aluminum, alloys, graphite or composite materials or various plastics could be used without departing from the spirit and scope of this invention. Although the locking mechanism 293 is preferably described in terms of the lever arrangement as described, it will be appreciated by those skilled in the art that numerous other locking mechanisms could be implemented to secure the track follower mechanism 282 in a retained position, such as a pin and aperture arrangement, a friction fit or wedge arrangement, a screw arrangement, a slot and ledge arrangement or the like.

Although the track follower mechanism 282 and locking mechanism 293 are preferably disposed on the front end 218 of the modular cart 220, it will be recognized that alternate embodiments are also contemplated by the present invention. For example, in an alternate embodiment, the track 114 and corresponding track follower mechanisms 282 could be positioned proximate the rear end 220 of the carts 212 with appropriate coupling and linkages could be provided for mechanical triggering the track follower mechanism 282 and locking mechanism 293 from the front end 218 of the cart 212. In another embodiment, the track followers 282 could be positioned at any position along the length of the cart 212, for example, in the middle of the length of the cart 112 corresponding to placement of the track 114, and electronic powered controls, such as battery operated solenoids, could be used to remotely operated the track follower mechanism 282 and locking mechanism 293.

Trusses, Hangers Stackers and Shelves

Referring now to FIGS. 69-73, the carts 112, 212 preferably include a truss system 364 having a truss or rod 366 and a truss hanger 376. The truss 366 comprises a truss hanger 376 and preferably comprises a first truss member 370 and a second truss member 372. The second truss member 372 is preferably shorter in length than the first truss member 370. The truss 366 can be selectively positioned on the wire-grille panel 300 using a plurality of truss hangers 376. The truss hangers 376 have a body 378 and a plurality of engagement members 380 disposed perpendicular to the body 378. The distance between each of the engagement members 380 generally corresponds to the spacing in the wire members on the wire-grille panel 300. Once a user has selected a position for the truss hanger 376, the hanger 376 can be positioned on, and engaged with, the wire-grille panel 300. A truss hanger 376 positioned on, and engaged with, a wire-grille panel 300 can be seen in FIG. 69.

Once a pair of truss hangers 376a, 376b are engaged with opposed front and end wire-grille panels 300a, 300b, the truss 366 can be placed onto the truss hangers 376. The body 378 of the truss hanger 376 preferably comprises a first truss member slot 382 and a second member slot 384, which the first truss member 370 and second truss member 372 fit, respectively. Including a first truss member 370 and second truss member 372 provides many benefits. For example, when helmet hangers 502 or pad hangers 504 populated with equipment and hung on the truss 366, the populated hangers will have a center of gravity that is below the second truss member. When a cart 12 having these populated hangers is moved along the track 14, the hangers are likely to swing back and forth in a pendulum motion that is parallel to the movement of the cart. The swinging hangers will make it more difficult to move the cart 12 as the momentum of the cart will be constantly changing due to the swinging hangers. By providing a first truss member 370 and second truss member 372, the populated hanger will be prevented from excessive swinging as the combined height of the truss members 370, 372 gives more height and surface area for the hangers to contact and thus more height and surface area to prevent swinging of the hangers. Alternatively, a single truss member could be used if the height was sufficient to provide the same height and surface area. The truss members 370, 372 are preferably constructed of tubular steel, although other materials such as aluminum, graphite or composite materials could be used without departing from the spirit and scope of this invention. The hangers 376 are preferably constructed of steel, although other materials such as aluminum, graphite or composite materials or various plastics could be used without departing from the spirit and scope of this invention.

The present invention includes a number of means for hanging equipment, such as football helmets and football shoulder pads. It will be noted that reference numerals in the 500's are generally used to denote the features and components of hangers and stackers adapted for use in the modular storage system 110 of the present invention. A helmet hanger 502 can be seen in FIG. 74. The helmet hanger 502 comprises a plurality of truss hooks 508 and a pair of generally opposed helmet hanger members 509. The helmet hanger 502 further comprises a plurality of helmet hooks 510 disposed vertically along the pair of generally opposed hanger members 509. As depicted in FIG. 75, the helmet hanger 502 is hung on the truss 366 and the helmet hanger 502 can then be populated with helmets. The helmet hanger 502 is preferably constructed of wire steel, although other materials such as graphite or composite materials or various plastics could be used without departing from the spirit and scope of this invention.

Another means for hanging equipment includes a pad hanger 504. Long and short pad hangers 504a, 504b can be seen in FIGS. 76-77. The pad hangers 504a, 504b comprise a truss hook 512 connected to a pad hanger member 513. The pad hangers also comprise a pad hook 514 generally opposed the truss hook 512. As depicted in FIG. 78, the pad hanger 504 is hung on the truss 366 and the pad hanger 504 can then be populated with pads. The pad hanger 504 is preferably constructed of wire steel, although other materials such as graphite or composite materials or various plastics could be used without departing from the spirit and scope of this invention. Alternative pad and helmet hangers 503 can be seen in FIGS. 79-80.

In one embodiment, the present invention preferably includes means for stacking equipment within the storage space of the carts 112, 212. A pad stacker 506 can be seen in FIGS. 81-87. The pad stacker 506 preferably comprises a stacker base 516, a stacking tower 518, a pad support 520, and a support channel 522. The stacker base 516 comprises a pair of generally opposed stacker frames 524a, 524b connected to a stacker frame cross tube 526. The stacker base 516 further comprises a pair of stacker handles 528a, 528b connected to the pair of generally opposed stacker frames 524. The stacker base 516, stacking tower 518, and support channel 522 are preferably constructed of steel, although other materials such as aluminum, alloys, graphite or composite materials or various plastics could be used without departing from the spirit and scope of this invention. The pad support 520 is preferably constructed of vacuum formed ABS, 0.125″ thick, with a haircell finish, although other materials could be used without departing from the spirit and scope of this invention.

The stacking tower 518 comprises a short tube loop 530 and a long tube loop 536, the tube loops 530, 536 connected at a bottom end 532 to a tower channel 531. At least one of the tube loops 530, 536 comprises a plurality of pin apertures 534. The pad support 520 comprises a pad support base 538 and a pad support member 540. The support channel 522 comprises a support plate 542 and a support channel member 544 connected to the support plate 542. The pad support 520 is then connected to the support plate 542 of the support channel 522.

To assemble the pad stacker 506, the stacking tower channel 531 is connected to the stacker frame cross tube 526 using fasteners 800. A pin is then inserted into one of the pin apertures 534 and the support channel 522 and pad support 520 are then placed onto the stacking tower 518 and lowered down until it rests upon the pin.

Once the pad stacker 506 has been assembled, the pad stacker 506 can be placed onto the cart base 116 or 216 of a cart. As can be seen in FIGS. 82, the pad stacker 506 is depicted in a cart 112. The stacker frames 524 are supported by the sides 130a, 130b of the cart base 116. A pad stacker 506 populated with pads can be seen in FIG. 81. In an embodiment of the present invention, the pad stacker 506 comprises wheels. When the pad stackers 506 are fuilly populated with pads, the pad stackers 506 will very likely be extremely heavy. Those involved with athletics will appreciate that a pad stacker 506 according to this embodiment can be moved along a surface without the need of lifting the pad stacker 506 off of the ground. When the pad stackers 506 have been populated and placed into the cart 112, each of the carts 112 can preferably hold more than eighty sets of shoulder pads.

As depicted in FIG. 3, the cart 112 according to an embodiment of the present invention also includes a shelf system 386. A shelf 388 can be selectively positioned on the wire-grille panel 300 using a plurality of shelf hangers 390. The shelf hangers 390 have a body 392 and a plurality of engagement members 394 disposed perpendicular to the body 392. The distance between each of the engagement member 394 generally corresponds to the spacing in the wire members on the wire-grille panel 300. Once a user has selected a position for the shelf hanger 390, the shelf hanger 390 can be positioned on, and engaged with, the wire-grille panel 300. Once a pair of shelf hangers 390 is engaged with opposed front and end wire-grille panels 300, the shelf 388 can be placed onto the shelf hangers 390. The shelf 388 is preferably constructed of sheet or wire steel, although other materials such as aluminum or plastic could be used without departing from the spirit and scope of this invention.

Installation

When the track is installed in a room not near the wall, an island stop 354 may be needed to create the bounds of the storage facility. In this type of embodiment, the storage facility will be generally defined by the track length 342 and the overall length of the carts as they are moved along the track 114. When the track is installed in an area not near a wall, track end caps 350 should be used to prevent damage to the exposed cross-section of the track 114 and also to provide a more pleasing appearance.

Once the modular storage system 110 of the present invention has been installed in a storage facility, the carts 112, 212 can be placed into the storage facility. In a preferred embodiment, a plurality of carts 112, 212 will be used, the plurality of carts comprising both retained carts 112 and modular carts 212. To place the retained carts 112 into the storage site, they generally would have to be lifted into the storage facility and positioned such that the track followers 184 are directly above the channel 404 of the track 114. Once the retained carts have been positioned, the track followers 184 should be allowed to engage with the channel 404 of the track 114. Once the track followers 184 engage with the channel 404 of the track 114, the retained carts can then be manually moved within the storage facility in a direction along the track 114.

To place modular carts 212 in the storage facility, the modular carts 212 can be manually moved over the track 114. By manually providing the modular cart 212 with enough momentum, the wheels 274 will roll over the ramped surfaces 406 of the track. The modular cart can then be placed so that the track followers 284 are directly above the channel 404 of the track 114. Once the modular carts 212 have been positioned, the track followers 284 should be allowed to engage with the channel 404 of the track 114. To do this, the plunger clip 295 and backer 297 should be pulled away from the track follower 284 so that the track follower can move freely. Once this is done, the track follower 284 will engage with the channel 404 of the track 114. The modular carts 212 can then be manually moved within the storage facility in a direction along the track 114.

In a preferred embodiment, there is preferably at least a portion of the track 114 that does not include a cart 112, 212. By having such a space, the carts 112, 212 can be moved along the track 114 and different carts 112, 212 can then be accessed proximate the portion not including a cart 112, 212.

In a preferred embodiment of the present invention, comprising modular carts 212 and retained carts 112, the modular carts 212 could contain uniforms and equipment in off-season use or uniforms and equipment that is not need to be taken out of the storage facility in the cart. This type of uniforms and equipment could be retrieved by individuals or taken to the individuals. The retained carts 112 could contain equipment that is needed out of the storage site 111 and easier to transport in a cart 112. Such equipment could include game uniforms and equipment. A modular cart 212 such as this could be simply loaded onto a trailer or into a vehicle and transported to a game site.

When the at least one track follower mechanism 282 on modular carts 212 is selectively engaged with the track 114, these carts 212 are operably retained by and movable only in a direction generally parallel to the track 114 permitting the cart to be selectively positioned within a storage position that is generally side-by-side with an adjacent cart 112, 212 along the track. In this position, the contents of the carts 112, 212 are accessible position as the carts 112, 212 are generally spaced apart with adjacent carts along the track.

As depicted in FIG. 88-89, when it is desired that the cart 212 remain in the storage facility, the rollers 292 of the track followers 284 are engaged with the channel 404 of the track 114. In this position, the cart 212 is movable in a direction along the track 114. However, as can be seen in FIGS. 91-92, the modular cart 212 is removable from the track 114 and movable in a direction generally perpendicular to the track 114 when the at least one track follower 284 is selectively disengaged from the track 114. FIG. 90 depicts a track follower 284 in an engaged position with respect to the track 114. By using a foot, as depicted in FIG. 91, the track follower 284 can be lifted so that the plunger clip 295 and backer 297 on the locking mechanism 293 retains the track follower 284 in a retained position. As depicted in FIG. 92, once the track follower 284 is in a retained position, the modular cart 212 is removable from the track 114 and movable in a direction generally perpendicular to the track 114.

If those using modular carts 212 desire to prevent the cart 212 from being removed from the storage facility, the plunger lock bracket 602 can be used to keep the track follower 284 in an engaged position. The plunger lock bracket 602 comprises a lock slot 604 that can be placed onto the locking portion 316 of a bracket 310 and a channel portion 606 that prevents the track follower 284 from being placed in a retained position. The plunger lock bracket 602 can be seen in FIG. 93.

The storage facility for the modular storage system 110 of the present invention can be located in any area of the room, facility or even a storage area in vehicle such as a truck or trailer. While it is preferred that the storage facility be located near a wall and in the corner of a room, it is contemplated that the storage facility be located in the center of a room. In this type of arrangement, there will likely be a need to place an island stop 608, as depicted in FIGS. 94-95, within the room. The island stop 608 comprises an island stop frame 610 and an island stop base 612 located on ends 614a, 614b of the island stop frame 610. The island stop base 612 comprises a substantially flat island stop plate 620 and an island stop bracket 618 connected to the island stop plate 620. The island stop bracket 618 preferably comprises an island stop glide 616 to prevent damage to the underside of the cart base 116. When the modular storage system 110 is used with an island stop 608, the island stop 608 is placed near the termination of a track 114. When a cart 112 is moved along the track 114 towards the island stop 608, the island stop 608 prevents the cart 112 from running out of track 114. This type of arrangement allows a user to place the modular storage system 110 in any location within a room or storage area.

The cart base 116/216, cart top 122/222, front end 118/218, and rear end 120/220 of the retained cart 112 and the modular cart 212 according to the various embodiments of the present invention provides the carts 112, 212 with a defined structural integrity that is sufficient to permit the manual movement of the carts 112, 212 in the direction that is generally parallel to the track 114 by a manual force greater than the coefficient of a rolling friction of the wheels 172/272 times the maximum gross weight exerted on one of the ends 118, 120 of the cart 112 and prevent binding along the length of the cart 112.
