The closure 41 is adapted to be maintained in its proper aligned position by means of guide members 42, and a knob or handle 43 is provided for manually moving the closure 41.
The numerals 44 indicate horizontally disposed brackets or shelf supports which are suitably afixed within the housing 11, and shelves or trays 45 are adapted to be supported on the brackets 44, and the shelves 45 are adapted to be made of reticulated or wire mesh material in order to insure that the cool air can circulate therethrough with a minimum amount of interference.
The refrigerator of the present invention further includes a plurality of independently adjustable leg assemblies which are each indicated generally by the numeral 46, and each of the leg assemblies 46 include a mounting member 47 that is secured to or formed integral with a lower corner portion of the housing 11. The numeral 48 indicates a leg which is adjustably connected to each mounting member 47, and the legs 48 are vertically disposed and the legs 48 may be held stationary in their adjusted positions by means of screw members or set screws 49. Base pieces 50 are aflixed to the lower ends of the legs'48. In FIGURE the refrigerator is shown in position above the usual hump 51 of a vehicle floor 52 which may form part of a conventional vehicle such as an automobile 53, and the numeral 54 indicates the dashboard of the vehicle.
Referring to FIGURE 6 of 'the drawings there is illustrated a modification wherein the refrigerator is shown being used 'in a difierent environment, and as for example the refrigerator can be used outdoors by hunters, campers or the like, and the numeral 55 in FIGURE 6 indicates a portion of a ground surface which may have an irregular contour and due to the provision of the independently adjustable leg assemblies 46, the refrigerator housing can be leveled by independently adjusting the legs to the proper height or length. The numeral 56 indicates a door or panel which may be hingedly connected to the housing by means of a hinge, 58, and the panel 56 may be supported by holding members such as chains 57 whereby various types of articles such as a glass 59 can be conveniently supported on the member 56 when'the member 56 is in a horizontal position. When the member 56' is not being used or when it is not needed, it can be folded up to a vertical position contiguous 'to thehousing so'that the parts will occupy a minimum amount of space for storage or shipment.
In FIGURE 6 the flexible hose 34 may be omitted.
and the unit may be used for causing air to circulate through the housing in a desired manner to permit the circulating air to help maintain the articles in the housing at a desired temperature or humidity.
As shown in FIGURE 4, the movable top section 25 may be provided with a hand grip 60 which can be cons,0 .a,11e
veniently gripped as for example when the top section 25 is to be swung upwardly on its hinge 26' in order to permit access to the interior of the housing so that articles can be removed or replaced therein.
FIGURES l, 2, 3 and 4 show the refrigerator being supported on a generally flat surface which is indicated by the numeral 61, and such a fiat surface 61 may be a suitable part of a vehicle such as an automobile floor or the like. As shown in'FIGURE 5 the adjustable leg assemblies 46 permit the refrigerator to .be'used over irregular surfaces such as'the. hump shaped portion 51 V of a vehicle floor 52.
It will be seen that with the'parts arranged as shown in the drawings, that various types of articles such as foodstuflfs, beverages, or the like can be conveniently maintained at a desired cool temperature, and for example the refrigerator 10 may be arranged in a suit-able part of a vehicle such as an automobile, and the flexible tube 34 can be connected to the outlet of a conventional vehicle air conditioner. Thus, cold air from the air conditioner will flow through the tube 34 and this air will be filtered by the member 33-so that clean cool air will.
enter the interior of the housing 11 whereby articles such as the articles 20, 21, 22' and 23 can be kept cool for a desired period of time. The air will circulate through the housing and leave through the slots or openings such as the openings 39 and the air can also leave through the element 28. If desired, certain of the closures '41 can be moved downwardly to closed position in order to close off one or more sets of the louvered sections tainers or the like can be supported in various parts of the housing. The articles can be supported on the shelves which are adapted to be made of foraminous material in order to permit air to circulate therethrough so that the most efficient circulation and cooling action can take place. The motor 36 is adapted to be connected to a suitable source of electrical energy 'by means of the wires 38, and the motor 36 is adapted to rotate the fan 85 which-can be used to facilitate the movement of air through the refrigerator.
The element 28 may be rotated so that the inclined portion 29 is at a desired angle so that for example maximum benefit can be taken of wind blowing in a certain direction in. order to use such outside wind to most efiiciently aid in outflow of air from the interior of the housing 11. In certain instances the motor 36 and fan 35 may be omitted. The refrigerator'may be supported on a flat surface such as the flat surface 61 which may 'be part of a vehicle floor or the like. Or, the refrigerator can be supported over a vehicle raised portion or hump 51 as shown in FIGURE 5, or else the unit may be used outdoors on irregular surfaces such as the surface 55 which may be ground surface in the vicinity of a wooded area, lawn or the like. Due to the provision of the leg assemblies 46 which can each be adjusted independently of the other, the housing can be maintained level. To adjust the leg assemblies 46 it is only necessary to unloosen the member such as the screw member 49 and the leg 48 can be moved to a desired position in order to cause the base piece to engage a raised or lowered surface and then the screw member 49 can then be tightened in order to maintain the legs 48 stationary in their adjusted positions.
The arrangement shown'in FIGURE 6 is such that the flexible tube 34' can be omitted so that cool air in the vicinity of a wooded area for example can be circulated through the interior of the housing to help mainso that the air can be caused to circulate through different areas or portions of the refrigerator housing as desired or required. Also, these closures 41 may be moved to a partially open or partially closed position in order to provide a further means for controlling the cooling in the refrigerator. Any suitable types of articles can be supported in the refiigerator housing, and for example a vacuum bottle such as the vacuum bottle 20 containing beverages can be arranged inside the housing, or else foodstuffs, beverages or the like in suitable contain the interior of the housing in a desired temperature or humidity. Or, an elongated flexible tube 34 can be used with the arrangement of FIGURE 6 whereby cool air can be conveyed from a'remotely positioned air conditioner of a vehicle, household air conditioner or the like so that with the refrigerator positioned outdoors the articles therein canbe kept cool. The top of the housing 11 can be used as a convenient support for various articles such as the vacuum bottle 20, as shown in FIG- URE 6. p
While the present invention has been described specifically for use as a refrigerator, it is to be understood that the same can be used for other purposes, as for example the device can be used for maintaining articles warm and in such use, the tube 34 can be connected to a suitable source of warm air such as a heater or the like as for example when the device is being used during winter months or during such times that it is desired to maintain various articles in a heated or warmed conditron. e
The device is adapted to be made compact and of a rugged construction so that it can be conveniently used and transported in -a vehicle or the like, and any suitable material can be used for fabricating the various parts, and such parts can be made in diiferent shapes or contours or sizes as desired or required. I
Due to the provision of the rotary element 28 with the louver-s 30'the'rein and the inclined upper section or portion 29,-the element 28 can be rotated or positioned at a desired location whereby the air can be directed outwardly in any direction desired after it has passed through the box or housing. The section 25 may be raised in order to facilitate the removal or replacement of foodstuffs or other articles from the interior of the housing. The blower or fan 35 can be used in such instances where the present invention is connected to an under-dash model the blower is not needed. A unit such as the present invention can be installed as optional equipment during the initial manufacture of the automobile or other vehicle, or else it can be readily installed in existing vehicles as a convenient accessory. Ditferent types of mounting means may be necessary or utilized in order to adapt the unit to difierent locations or vehicles. The device may be made light in weight and of a rugged and compact construction so that it will be portable, and as shown in FIGURE 5 the device can be used so that its legs straddle the hump 51 in the floor board whereby the base pieces 50 will rest solidly on the floor 52.
Although the invention described is fully capable of achieving the objects and providing the advantages hereinbefore mentioned, it is to be understood that it is merely illustrative of the presently preferred embodiment of the invention and that it is not to be limited to the details of construction herein described other than as defined in the appended claim.
