Description
- The present application claims priority to U.S. Provisional Application No. 60/523,044, entitled “LOGISTICAL MANAGEMENT OF FIELD EQUIPMENT FOR OPERATIONAL UNITS” filed Nov. 17, 2003, U.S. Provisional Application No. 60/543,047, entitled “LOGISTICAL MANAGEMENT OF FIELD EQUIPMENT FOR OPERATIONAL UNITS” filed Feb. 9, 2004, U.S. Provisional Application No. 60/599,227, entitled “LOGISTICAL MANAGEMENT OF FIELD EQUIPMENT FOR OPERATIONAL UNITS” filed Aug. 5, 2004, and U.S. Provisional Application No. 60/616,538, entitled “LOGISTICAL MANAGEMENT OF FIELD EQUIPMENT FOR OPERATIONAL UNITS” filed Oct. 6, 2004. The disclosures of the aforementioned provisional applications are hereby incorporated by reference to the extent not inconsistent with the present disclosure.
- The present invention relates generally to movable storage cabinets. More particularly, the present invention relates to a track system for use with a modular storage system for the logistical management of operational units.
- 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. Such high-density storage solutions have movable shelving units carried on a rail system typically installed in a raised floor such that the shelving units can be slide together and apart to provide for more space efficient storage as shown, for example, in U.S. Pat. Nos. 6,688,708, 6,669,314, 6,644,213, 6,371,031, 6,231,138, 6,161,485, 4,557,534, 4,432,589, and 3,829,189. Because these systems are fixed on dual tracks, those using the system are not allowed to bring the storage system to an off-site area. Those wishing to access the storage must come to the storage facility and cannot bring the storage system with them. In addition, solid panels enclose the shelves and/or bins in the storage system, 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 shelves and/or bins in appropriate dimensions for different sized articles. Also, although the storage solutions manufactured by Spacesaver Corporation have been modified to accommodate athletic equipment, the solutions are generally designed for document storage and therefore cannot fulfill all of the aforementioned equipment storage needs of logistical management units.
- Other similar movable storage systems have been developed for storage units that are fixed onto and movable along dual tracks. Some exemplary systems can be seen in U.S. Pat. Nos. 6,644,213, 6,371,031, 6,112,917, 6,027,190, 5,160,189, 4,597,615, 4,467,924, 4,307,922, 4,256,355, and 6,161,485. The storage units in these storage systems are movable along the dual tracks and the contents can be accessed when two adjacent units are separated by a space. However, the units in these storage systems cannot be removed from the dual tracks and taken out of the storage site. As a result, those desiring to transport equipment to an off-site area will not be able to do so using the units in the storage systems described in these patents.
- While the vast majority of storage systems are fixed within a given facility, there have been a few attempts to provide storage units that can be removed from the storage facility. U.S. Pat. No. 4,807,765 describes a space saving system in which the storage units are movable on casters along adjacent dual track arrangements within a storage facility to provide front-to-rear movement of adjacent carts that are stored in a side-by-side relation in their storage position. While these carts could be removed from the track and taken out of the storage facility, the carts are not designed to accommodate equipment that is used by field operational units. In addition, the carts or shelves can only be removed off the end of the tracks. U.S. Pat. No. 6,241,106 is directed to a space saving system in which the storage units are shelf main bodies that are provided with pivotable casters and are movable along a dual set of overhead rails within a storage facility. While these shelf main bodies can be removed from the overhead rails so as to function as conveyer wagons, as with the above-listed patents, neither the shelf main bodies nor the overhead rails are not designed to accommodate equipment that is used by field operational units.
- U.S. Pat. No. 4,802,622 describes a single-track system in which the modules are movable along a track within a storage site. However, the modules do not include wheels and are therefore cannot be removed from the track and taken out of the storage site. U.S. Pat. Nos. 3,801,176 and 3,286,651 describe systems in which the modules are movable along tracks within a storage site. However, the modules must be moved from the end of the tracks in order to remove them from the tracks and storage facility.
- 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 facilities and areas in which the equipment is used. There is also a need for a track system to which the storage modules can be quickly and easily engaged and disengaged. When the carts are located within a storage facility, engaged with the track, and populated with equipment, the carts should be easily movable by manual force along the track without the cart binding or canting.
- In an embodiment of the present invention, a track system for use with a modular storage system includes a single track operably positioned on a floor and extending along a track path, a plurality of carts, each cart having a frame that includes a pair of ends separated by a length, the frame having a defined structural integrity between the pair of ends and including structure defining at least one storage space that is carried by the cart and having a defined maximum gross weight when the at least one storage space is occupied. The cart further includes a track follower mechanism that is operably attached to one of the pair of ends of the cart. In one embodiment, the track follower mechanism includes at least a portion of which is movable between a retained position and an engaged position. The cart further includes at least three wheels that are operably attached to and support the cart relative to the floor, the at least three wheels having a defined coefficient of rolling friction relative to the floor, such that a cart is operably retained by the track and manually movable only in a direction generally parallel to the track path when the at least one track follower is engaged with the track. The modular storage system is designed such that the structural integrity of the cart is sufficient to permit manual movement of the cart in the direction generally parallel to the track path by a manual force greater than the coefficient of a rolling friction of the wheels times the maximum gross weight exerted on one of the pair ends of the cart and prevent binding of the frame along the length of the cart.
- In another embodiment of the present invention, a rail system for use with a modular storage system comprises a single rail that is disposed on a floor and extends along a rail path, the rail having a channel that extends along the rail that is generally parallel to the rail path. The rail system further includes a rail follower mechanism that is operably attached to a cart, the rail follower mechanism having at least a portion of which is movable between a retained position and an engaged position, the movable portion comprising an elongate member and a roller disposed proximate a lower end of the elongate member, such that when the at least one rail follower is in the engaged position the roller is selectively engageable with the channel and movable along the rail path within the channel, the roller having a defined coefficient of sliding friction and a defined coefficient of rolling friction relative to the channel such that the defined coefficient of sliding friction and the defined coefficient of rolling friction permit the cart to be manually moved along the rail in a direction generally parallel to the rail path with a minimal amount of effort.
- In an embodiment of the present invention, when the rail follower mechanism of the rails system is in the engaged position, at least a portion of the rail follower mechanism is floatable in the vertical direction allowing the rail system to be used on an uneven floor.
- In an embodiment of the present invention, the wheels in the rail system comprise a material having a coefficient of rolling friction selected to minimize the rolling friction with the floor. In another embodiment of the present invention, the at least one roller in the rail system is made of a material having a coefficient of rolling friction that is selected to minimize the rolling and/or sliding friction with the channel of the track. In another embodiment of the present invention, the wheels in the rail system have a generally convex profile selected to minimize the rolling friction with the floor.
- In an embodiment of the present invention, the rail in the rail system is unitary. In another embodiment, the rail in the rail system is made out of at least two rail sections. In this embodiment, the at least two rail sections are connected using at least one pin. In another embodiment of the present invention, the base in the rail system includes a locking portion that selectively retains the rail follower mechanism in the retained position.

FIGS. 1-3 , amodular storage system 110 according to an embodiment of the present invention generally comprises atrack 114 and a plurality ofcarts carts 112 are arranged in a storage facility along asingle 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, thetrack 114 is preferably positioned onto and connected to a pre-selected portion of a floor. In a newly constructed facility, thetrack 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 inFIG. 3 ) and modular carts 212 (as shown inFIG. 55 ). As can be seen inFIG. 3 , the retainedcarts 112 populated with uniforms and equipment are preferably movable by manual force in a direction that is generally parallel to and along thetrack 114. Themodular carts 212 as depicted inFIG. 55 are also preferably movable along thetrack 114. In addition to being movable along thetrack 114, themodular 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 andmodular carts 212 can be of any number and mix, depending upon the length of thetrack 114 installed at the storage facility and the width of eachcart 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 inFIG. 1 , some of the retainedcarts 112 are full width (112 a) and others are half width (112 b). Preferably, all of thecarts carts track 114 and a length in a direction generally perpendicular to thetrack 114. Similarly, thecarts - The
carts 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 andcarts 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, themodular 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 amodular 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 thecarts - 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.

In this type of embodiment, the storage facility will be generally defined by thetrack length 342 and the overall length of the carts as they are moved along thetrack 114. When the track is installed in an area not near a wall, trackend caps 350 should be used to prevent damage to the exposed cross-section of thetrack 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, thecarts carts carts 112 andmodular carts 212. To place the retainedcarts 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 thechannel 404 of thetrack 114. Once the retained carts have been positioned, the track followers 184 should be allowed to engage with thechannel 404 of thetrack 114. Once the track followers 184 engage with thechannel 404 of thetrack 114, the retained carts can then be manually moved within the storage facility in a direction along thetrack 114. - To place
modular carts 212 in the storage facility, themodular carts 212 can be manually moved over thetrack 114. By manually providing themodular cart 212 with enough momentum, thewheels 274 will roll over the rampedsurfaces 406 of the track. The modular cart can then be placed so that thetrack followers 284 are directly above thechannel 404 of thetrack 114. Once themodular carts 212 have been positioned, thetrack followers 284 should be allowed to engage with thechannel 404 of thetrack 114. To do this, theplunger clip 295 andbacker 297 should be pulled away from thetrack follower 284 so that the track follower can move freely. Once this is done, thetrack follower 284 will engage with thechannel 404 of thetrack 114. Themodular carts 212 can then be manually moved within the storage facility in a direction along thetrack 114. - In a preferred embodiment, there is preferably at least a portion of the
