BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a portable ice chest and more particularly to an improved portable ice chest having a lid or lid sections operable between open and closed positions with an improved foot operable linkage.
2. General Background of the Invention
Portable ice chests are commercially available and commonly used to carry many food items. One of the most popular uses of a portable ice chest is that of housing fish caught by a fisherman while on a dock or a boat. When a fisherman catches a fish, the fisherman typically is holding the fish in one hand and a rod and reel in the other hand. This presents a problem for the fisherman in that he or she must set the rod and reel down in order to open the lid of an ice chest and place the fish inside. Temporarily relinquishing the fish rod invites damages to the rod and interrupts fishing activity, hampering the fisherman in his or her attempt to present another bait or lure to the fish still swimming in the vicinity.
Several patents have issued that are directed to containers, and/or portable ice chests insulated containers, some of which are foot operated. The following table lists examples of possibly relevant patents. Some of these patents are directed to insulated containers. Other patents are directed to waste containers having a foot operated mechanism.

DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1-7 show a portable ice chest that is foot operated and wherein a unique operating mechanism is provided. In FIGS. 1-4, the portable ice chest 10 provides container body 11 having an outer shell 12 and an inner shell 13. An insulative layer 14 of air, foam, or other insulative material is provided in between the outer shell 12 and the inner shell 13.
Container body 11 provides a bottom panel 15, front panel 16, rear panel 17 and side panels 18, 19. The side panels can include left side panel 18 and right side panel 19.
Container body 11 has an open top 20 to be used to access one or more cool compartments 31. A pair of lids 21, 22 or covers are each pivotally attached to container body 11 at pivots 32, 33 respectively.
Each lid or cover 21, 22 is operable with a foot pedal. The foot pedal 23 opens lid or cover 21. The foot pedal 24 operates or opens the lid or cover 22. Linkages are provided for connecting each lid 21, 22 with its foot pedal 23, 24. The linkage 25 extends between foot pedal 23 and lid or cover 21. Linkage 26 extends between foot pedal 24 and lid or cover 22.
Pivotal connections join each foot pedal to its linkage. Each foot pedal 23, 24 is pivotally attached to container body 11. Foot pedal 23 attaches to container body 11 at pivotal connection 27. Foot pedal 23 also forms a pivotal attachment to linkage 25 at pivotal connection 30.
Foot pedal 24 is pivotally attached to container body 11 at pivotal connection 28. Foot pedal 24 forms a pivotal attachment to linkage 26 at pivotal connection 34.
In order to elevate either of the lids or covers 21, 22 a user simply depresses the foot pedal 23 or 24 associated with the lid or cover 21, 22. A fisherman can open either end 21 or 22 without opening the other end 21 or 22. The other lid or cover 21, 22 remains closed. This is important when depositing fish in the ice chest because the closed lid or cover 21, 22 helps prevent escape of the fish after it has been deposited within the compartment 31 of the container body 11. An optional (preferably removable) divider or baffle 35 can be used to divide the cooled section 31, so that contents can be segregated such as the fish caught by first and second fishermen, or fish separated from food and drinks.
By placing the foot pedals 23, 24 on opposing ends or side portions of the container body 11, the ice chest 10 of the present invention can be accessed from two different directions such as by fisherman that are positioned on opposing sides of the ice chest such as on opposite sides of a boat. Thus, one fisherman can be fishing on the port side of a boat and deposit his or her fish by depressing the foot pedal 23. Another fisherman can be fishing on the starboard side of the boat and deposit his or her fish by depressing the foot pedal 24. This feature has great importance for center console style fishing boats that typically provide an ice chest in front of the center console, the ice chest being accessible from either the port side or starboard side of the boat. This feature is also important on boats that have ice chests at the rear of the boat, next to the stern. Such as a stern mounted portable ice chest 10 is also accessible by a first fisherman using the pedal closest to the port side of the boat and a second fisherman using the pedal closest to the starboard side of the boat.
FIGS. 5-7 show a second embodiment of the apparatus of the present invention, designated generally by the numeral 40. Portable ice chest 40 can utilize the same container body 11 of the present invention. In FIGS. 5-7 portable ice chest 40 provides a full length foot pedal 41 that extends almost the full width 51 of body 11 from one side panel 18 to the other side panel 19 as seen in FIG. 5. The single full length foot pedal 41 operates a pair of linkages 42, 43. Linkages 42, 43 can be pushrods. The foot pedal 41 is attached to the container body 11 at pivotal connection 44. The full length foot pedal 41 attaches to a first linkage 42 at pivotal connection 45 and to a second linkage 43 at pivotal connection 46.
Each linkage 42, 43 attaches to a common lid 50 with a pivotal connection. A pivotal connection is formed at 47 between lid 50 and linkage 42. A pivotal connection 48 is formed between lid 50 and linkage 43.
In FIGS. 5-7, arrow 49 illustrates that foot pedal 41 extends substantially the full length of container body 11, spanning at least half, preferably two thirds or more preferably three fourths of the distance between left side panel 18 and right side panel 19. When a user steps on pedal 41 at its front end portion 54 the user's foot 55 moves downwardly with the front end portion 54 as indicated by arrow 52 in FIGS. 2, 4 and 7. The foot pedal 41 pivots at pivot 45, 46 thus elevating the rear end portion 56 of pedal 41 and elevating each of the linkages or pushrods 42, 43 as shown in FIG. 7. Lid 50 is hingedly connected to body 11 at hinge 57. The hinge 57 is positioned behind the pivotal connections 47, 48 as shown in FIGS. 6 and 7. Thus, when the linkage or pushrod 42, 43 is elevated in FIG. 7, the lid 50 also elevates and pivots about its hinge 57 as shown by arrow 53 in FIG. 7 thus opening the compartment or interior 31 of ice chest 40. When the user removes his or her foot 55, the weight of the lid 50 closes the lid via gravity.
In one embodiment a single lid can be included. In one embodiment the upper brace for the two portion lid can be omitted making the interior a whole/single volume.
FIG. 8 shows an alternative lid construction 21′, 22′ of the embodiment shown in FIGS. 1-4. Container body 11 provides a bottom panel 15, front panel 16, rear panel 17 and side panels 18, 19. The side panels can include left side panel 18 and right side panel 19. Container body 11 has an open top 20 to be used to access one or more cool compartments 31. A pair of lids 21′, 22′ or covers are each pivotally attached to container body 11 at hinges 57 (the hinges 57 for lid cover 21′ are not shown as they are located on rear panel 17)
Each lid or cover 21′, 22′ is operable with a foot pedal. The foot pedal 23 opens lid or cover 21′. The foot pedal 24 operates or opens the lid or cover 22′. Similar to the construction shown in FIGS. 1-4, linkages are provided for connecting each lid 21′, 22′ with its foot pedal 23, 24. The linkage 25 extends between foot pedal 23 and lid or cover 21. Linkage 26 extends between foot pedal 24 and lid or cover 22. In FIG. 8, the pivoting connection 30 for pedal 23/lid 21′ will be located on next to/under rear panel 17 instead of left side panel 18, and the pivoting connection 34 for pedal 24/lid 22′ will be located next to/under front panel 16 instead of right side panel 19. In this manner lids 21′ and 22′ can open respectively in the direction of arrows 100,110 as show in FIG. 8.
Also alternatively the foot pedals 23,24 and their associated linkage systems connected to lids 21′,22′ in FIG. 8 can be re-positioned to protrude from side panel 18 (effectively rotating these linkage systems by 90 degrees). Dimensional changes would have to be made to account for the differing lengths of the front/rear to side panels.
In an alternative construction of two lid 21′,22′ container 10′ two sets of opposed pedals 41 and 41′ and associated linkage systems for opening lids 21′ and 22′ can be used. These opposed linkage system can be substantially the same as shown in the single lid 50 embodiment disclosed in FIGS. 5-7. For lid 21′ pedal 41 and its associated linkage system can be used in substantially the same configuration shown in FIGS. 5-7 (in this case lid 21′ would be one half the size of lid 50 as shown in FIG. 8). For lid 22′ a pedal 41′ and its associate linkage system could be used but with peal 41′ facing in the opposite direction of pedal 41 shown in FIG. 6 (protruding from rear panel 17 instead of front panel 16). That is pedal 41′ connected to lid 22′ would protrude from rear panel 17 with the pivotal connections 45′,46′ being under front panel 16. In this embodiment pivot point 44 would preferably be located in the center of bottom panel 15.
FIG. 9 is a perspective view of another alternative embodiment 10″ wherein elastic straps 72,74,76,78 are used to assist in opening and maintaining the lid 21,22 sections in an open condition (which lid sections 21,22 are traverse or width wise), wherein the lids 21,22 are shown in a closed and locked state. FIG. 10 shows the embodiment of FIG. 9 with the lids 21,22 in an open state. The elastic straps can be any resilient elastic members such as rubber, spring, or other elastic members. The straps can be connected via connection points 72′/72″; 74′/74″; 76′/76″; and 78′/78″. Catch or lock 80 can be used to maintain the lid sections 21,22 in a closed or locked state. When catch or lock 80 is unlocked straps 72,74,76,78 can force open lids 21,22 as schematically indicated by arrows 120,130 along with the changes in state from closed to open in FIGS. 9 and 10. In an alternative embodiment lids 21,22, when closed, have some frictional locking condition even when catch or lock 80 is in an unlocked state, but when lock 80 is unlocked and either lid 21 and/or 22 is opened slightly, then straps 72,74,76,78 take over and more fully open lids 21,22 (e.g., the remainder of the way and keep these lids open until a user closes the lids, and/or locks again lock 80). To close lid sections 21 and 22 a downward force in the opposite directions of arrows 120,130 is placed on these lid suctions to close them and latch or lock 80 is locked (or alternatively frictional force between lids 21,22 between themselves or the container when lids 22,22 are closed can be used to maintain the closure (and/or with the closing torque about their hinges caused by the weights of lids 21,22 in a horizontal position can be used to maintain closure).
FIG. 11 is a perspective view of another alternative embodiment 10″ ‘ wherein elastic straps 72,74,76,78 are used to assist in opening and maintaining the lid 21′,22′ sections open (which lid sections 21′,22′ are length wise), wherein the lids 21′,22′ are shown closed. The elastic straps can be any resilient elastic members such as rubber, spring, or other elastic members. The straps can be connected via connection points 72′/72″; 74′/74″; 76′/76″; and 78′/78″. Catch or lock 80 can be used to maintain the lid sections 21′,22′ in a closed position. When catch or lock 80 is unlocked straps 72,74,76,78 force open lids 21′,22′ as schematically indicated by arrows 140,150. In an alternative embodiment lids 21′,22′ have some frictional locking condition even when catch or lock 80 is in a locked state, but when lock 80 is unlocked and either lid 21′ and/or 22′ is opened somewhat then straps 72,74,76,78 take over and open lids 21′,22′ the remainder of the way and keep these lids open until a user closes the lids (and/or locks again lock 80). To close lid sections 21′ and 22′ a downward force in the opposite directions of arrows 120,130 is placed on these lid suctions to close them and latch or lock 80 is locked (or alternatively frictional force between lids 21′,22′ between themselves or the container when lids 22′,22′ are closed can be used to maintain the closure (and/or with the closing torque about their hinges caused by the weights of lids 21′,22′ in a horizontal position can be used to maintain closure).
FIG. 12 is a side sectional view of 10″″ which is a modified version of the single lid embodiment shown in FIGS. 5-7, wherein elastic straps 72, 74 are used to assist in opening and maintaining the lid section 50, wherein the lid 50 is shown closed. FIG. 13 shows the embodiment of FIG. 12 with the lid 50 section open. Catch or lock 80 can be used to maintain the lid section 50 in a closed position. When catch or lock 80 is unlocked straps 72,74 can force open lid 50 as schematically indicated by arrows 160,170 along with the changes in state from closed to open in FIGS. 12 and 13. In an alternative embodiment lid 50 has some frictional locking condition even when catch or lock 80 is in an unlocked state, but when lock 80 is unlocked and lid 50 is opened somewhat then straps 72,74 take over and open lid 50 the remainder of the way and keep this lid 50 open until a user closes the lids (and/or locks again lock 80). Alternatively, pedal 41 can be depressed where straps 72,74 assist in opening lid 50 further as described above, or alternatively pedal and linkage can be omitted relying only on straps 72,74 to open lid 50.
