It will be further understood that FIGS. 1-24 are merely schematic representations of the device and some of the components may have been distorted from their actual scale for pictorial clarity.

(14) In accordance with the present invention, and referring to FIGS. 1.1 and 1.2, the refrigerator box 50 is illustrated. The refrigerator box 50 is preferably a stand-alone, all-in-one refrigerator provided in a box configuration and having doors 52 situated at one end of the refrigerator box 50. The refrigerator box 50 is used for storing food and drink (e.g., products or contents) and keeping those products or contents in cold or cool temperatures.

(15) An external frame 54 is attached to the refrigerator box 50 adjacent an opening 56 within the refrigerator box 50 such that an air-conditioning unit may be retained within the external frame to allow and permit force air cooling through the opening 56 and into the refrigerator box 50 to keep the products or contents cold or cool within the inside 51 of the refrigerator box 50.

(16) Situated underneath or on the bottom, but an integral part of the refrigerator box 50, is a storage compartment 58, and also as more fully or clearly illustrated in FIGS. 2.1 and 2.2. Refrigerator box wheels 60 are used to enable the stand-alone, all-in-one refrigerator to be moved or transported (e.g., for example, to and from location where refrigerator box 50 is packed or loaded with the products or contents, for moving onto a truck bed or other trailer for transporting the refrigerator box 50 to the destination or location for delivery, and to and from the truck bed or other trailer and the destination or location where products or contents contained within the refrigerator box 50 are to be delivered and unloaded).

(17) Within the storage compartment 58 are parallel, opposing tracks 62, 64. Each of these opposing tracks 62, 64 run longitudinally from one end to the other of the storage compartment 58. In the preferred embodiment, the opposing tracks 62, 64 are centered within the storage compartment 58, although any position of the opposing tracks 62, 64 will work in Applicant's invention provided the opposing tracks 62, 64 work as described herein. Also, in the preferred embodiment, each opposing tracks 62, 64 has a top rail 66 and a bottom rail 68.

(18) A built-in ramp assembly 70 is further contained within the storage compartment 58, as illustrated in FIGS. 3.1 and 3.2, 4.1 and 4.2. In the preferred embodiment, the ramp assembly 70 comprises a head frame 72, articulating arms 74, and a ramp 76 having hooks 84, and is moveable within the storage compartment 58.

(19) The head frame 72 comprises a head frame wheels 78, 80 connected by a frame member 82. In the preferred embodiment, the head frame wheels 78, 80 and as further illustrated below, are situated within the opposing tracks 62, 64, respectively, and specifically between the top rail 66 and bottom rail 68, respectively. In this manner, and as further discussed below, the head frame wheels 78, 80 are moveable (e.g., slide, roll, etc. . . . ) within the tracks 62, 64 to traverse or move the ramp assembly 70 through the storage compartment 58; and, as further discussed below, this is to facilitate the movement of the ramp assembly 70 between a stowaway position 86 (e.g., when the ramp assembly 70 is fully stored within the storage compartment 58 of the refrigerator box 50) and an angled position 88 (e.g., when the ramp assembly 70 is removed from the storage compartment 58) and situated in connection with the refrigerator box 50 below the doors 52 for loading and unloading the refrigerator box 50 without having to disengage the ramp while the refrigerator doors 52 are being opened and closed. The articulating arms 74, as described in more detail below, are preferably integrally connected between the frame member 82 of the head frame 72 and the ramp 76, and provide a first pair of arms 122, a second pair of arms 124, a third pair of arms 126, a fourth pair of arms 128, a fifth arm 130, and a sixth arm 132, and further providing a first pivot axis [132] 140, a second pivot axis 134, a third pivot axis 136, and a fourth pivot axis 138.

(20) As illustrated in FIGS. 5 through 24, the process and method of using Applicant's invention in accordance with the present invention is more fully illustrated.

(21) In FIG. 5, and in the preferred embodiment, the doors 52 may remain closed to keep the products and contents cold or cool within the refrigerator box 50. Alternatively, if desired, and for a short period of time, the doors 52 could likewise be opened.

(22) In FIGS. 6 through 8, spring-loaded, retractable pins 90, 92 are removed from a securing latches 94, 96 situated below the doors 52 adjacent the storage compartment 58.

(23) In FIG. 9, using the opposing handles 98, 100 situated at the end of the ramp 76, the ramp 76, fully stored within the storage compartment 58 of the refrigerator box 50 and in a stowaway position 86, is begun to be pulled from the storage compartment 58. In this manner, the head frame wheels 78, 80 are moveable (e.g., slide, roll, etc. . . . ) within the opposing tracks 62, 64 to allow the ramp assembly 70 to traverse or move through and out from the storage compartment 58.

(24) In FIGS. 10 through 11, the ramp assembly 70 is continued to traverse or move through and the storage compartment 58 until the head frame 72 engages a stop within the storage compartment 58. When this occurs, the ramp 76 will have fully exited or have been completely removed from the storage compartment 58 but remain connected to the head frame 72 and moveable in relation to the head frame 72 through the use of the articulating arms 74.

(25) In FIGS. 12 through 15, the ramp 76 is lifted upwards and with the hooks 84, fixedly attached and extending outwardly from the bottom of the ramp 76, being inserted, dropped and/or received into the retaining members 102, 104, fixedly secured and situated below the doors 52 adjacent the storage compartment 58 to thereby hold the ramp 76 in position at the back of the refrigerator box 50 to load and unload product or contents from the refrigerator box 50. The resulting position of the ramp 76 being situated in an angled position 88.

(26) In the preferred embodiment, and referring to FIGS. 12 and 3.1, the upward motion and rotation of the ramp 76 to lift the ramp 76 for placement of the hooks 84 into the retaining members 102, 104 is facilitated by the articulating arms 74. Each of the articulating arms 74 provide first arms 106 (also referred to as the first pair of arms 122), 108 (also referred to as the second pair of arms 124), the third pair of arms 126, and the fourth pair of arms 128. The second arms 110 (also referred to as the fifth arm 130), 112 (also referred to as the sixth arm 132). The first arms 106, 108 (or the first pair of arms 122 and the second pair of arms 124) are preferably fixedly secured to the head frame 72 and pivotally connected, about a first pivot axis 114 (also referred to as the first pivot axis 140 and the third pivot axis 136), to the second arms 110, 112 (or the third pair of arms 126 and the fourth pair of arms 128). The second arms 110 (or the fifth arm 130), 112 (or the sixth arm 132) are pivotally connected, about a second pivot axis 116 (also referred to as the second pivot axis 134 and the fourth pivot axis 138), to the ramp 76. In this manner, when in use and in order for the ramp 76 to be releaseably connected to the retaining members 102, 104 requires: (1) lifting the ramp 76 in the upward direction, (2) rotating the second arms 110 (or the fifth arm 130), 112 (or the sixth arm 132) about the first pivot axis 114 (or the first pivot axis 140 and the second pivot axis 136) in relation to the first arms (or the first pair of arms 122 and the second pair of arms 124), (3) rotating the second arms (or the fifth arm 130), 112 (or the sixth arm 132) about the second pivot axis 116 (or the second pivot axis 134 and the fourth pivot axis 138) in relation to the ramp 76, and then (4) inserting, dropping and/or receiving the hooks 84 into the retaining members 102, 104.

(27) In FIG. 16, once the ramp 76 is releaseably connected to the retaining members 102, 104, a lip 118 on the ramp 76 is rested over the edge 120 of the refrigerator box 50.

(28) In FIGS. 17 and 18, and at this point, with the ramp 76 positioned at the angled position 88 (e.g., when the ramp assembly 70 is removed from the storage compartment 58) and situated in connection with the refrigerator box 50 below the doors 52 and behind the rear of the refrigerator box 50 (e.g., and not within the refrigerator box 50), the refrigerator box 50 and products and contents are ready for loading and unloading from the refrigerator box 50 without having to disengage the ramp 76 while the refrigerator doors 52 are being opened and closed. Thus, the refrigerator doors 52 can be opened and closed, as desired, and products and contents removed, likewise as desired, while the ramp 76 remains in continuous, uninterrupted use.

(29) In FIGS. 19 through 24, once all of the products and contents have been removed from the refrigerator box 50 and the ramp 76 is no longer necessary, the process for returning the ramp 76 from the angled position 88 back to the stowaway position 86 within the storage compartment 58 is reversed.

(30) Based on the foregoing, Applicant's refrigerator box 50 provides at least the following advantages: (a) This is a stand-alone, all-in-one refrigerator box that includes refrigerator and built-in (or stowaway) ramp. This all-in-one refrigerator box may be transported on the top of a truck bed, but otherwise may have nothing to do with a truck; (b) Attachment of the ramp to the rear of the refrigerator box (e.g., not within the box) to allow the doors to the refrigerator to be opened and closed while ramp is in use. Thus, with the ramp is not being required to be disengaged from the refrigerator box to open and close the refrigerator, this (i) prevents unnecessary opening and closing of the refrigerator and (ii) prevents loss of temperature or exchange of heat into the refrigerator to collectively thereby allow the refrigerator to keep the contents inside the refrigerator to remain at their current cooler or colder temperatures;

(31) More specifically, the reciprocal retaining members to hold the ramp are located at the back of the refrigerator box, not inside the bed of the refrigerator box. This allows the door or doors to the refrigerator box to be freely and continuously opened and closed without having to remove the ramp; while further allowing the ramp to be used to remove the contents from the refrigerator box the entire time. This is very important as this refrigerator box is also a refrigerator and the door or doors must remain closed as much as possible. (c) The stowaway ramp is stored within the storage compartment providing a low profile clearance or low height, and preferably may be limited to four inches (4). In other words, the storage section that holds the head frame, articulating arms, and ramp only needs a low clearance or low height to store these when not in use; (d) The stowaway ramp is secured within the storage compartment by the built-in, retractable, spring-loaded containment pins. In other words, the articulating arms remain connected to both the head frame and the ramp, and then permits the rotation of the articulating arms to allow the ramp (removed from the storage compartment) to be lifted for placement at the back end of the refrigerator box; (e) The stowaway ramp has only two (2) pivot points: at the ramp and between ramp and wheel.

(32) Thus, there has been provided a refrigerator box and method of using the same. While the invention has been described in conjunction with a specific embodiment, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it in intended to embrace all such alternatives, modifications and variations as fall within the spirit and scope of the disclosure contained herein and appended claims.
