DESCRIPTION OF EMBODIMENT(S) OF THE INVENTION
The present invention is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It may be evident, however, that the present invention may be practiced without these specific details. In other instances, well-known structures and devices are shown in schematic form in order to facilitate describing the present invention.
A galley cart 10 adapted to carry goods in accordance with an embodiment of the invention is illustrated in FIG. 1. The galley cart 10 is adapted to be used in a passenger airplane but could alternatively be used in other environments like in a passenger train or, inter alia, in the medical field. The galley cart 10 illustrated in FIG. 1 comprises a body 14 defining an upper portion 18, a right longitudinal portion 22, a left longitudinal portion 26 and a bottom portion 30. The body 14 can be described as an assembled construction using panels 34 and junction members 38 therebetween simultaneously supplying the aesthetic envelope of the galley cart 10 and the structure providing its mechanical strength.
The upper portion 18, the right longitudinal portion 22, the left longitudinal portion 26 and the bottom portion 30 of the body 14 are connected together to obtain a strong unified structure in accordance with an embodiment. Alternatively, the upper portion 18, the right longitudinal portion 22, the left longitudinal portion 26 and the bottom portion 30 of the body 14 are connected together with intervening junction members 38. Illustrative embodiments described herein are using a variety of junction members 38 to interconnect adjacent portions 18, 22, 26, 30. The body 14 of the illustrated embodiment is forming a cavity having four planar side portions 18, 22, 26, 30. The cart 10 can be embodied in a single door 50 configuration and consequently includes a rear transversal portion 48, in contrast, the cart 10 can also be embodied in a double doors 50 configuration (not illustrated) without departing from the scope of the present specification. A door 50 is pivotally secured with the hinge 54 to the body 14 and is moveable between opened position and a closed position closing a corresponding door opening 46. The door 50 is configured to be secured to the door opening 46 with a locking mechanism 58 that can be selectively actuated by user to secure the door 50 to the door opening 46 and to open the door 50 to get access to content therein. It can be appreciated that the wall thickness of the different portions 18, 22, 26, 30 can have different thicknesses adapted to sustain the specific mechanical loads applied thereto. In other words, the construction of the galley cart 10 can be optimized to only use the required material at the right place and therefore reduces the weight while providing the appropriate mechanical resistance. For example, the panel of the upper portion 18 can have a thinner wall section than the panel of the bottom portion 30 because the upper portion 18 does not bear the weight of the entire galley cart 10. Additional details about the construction of the body 14 will be provided below.
Still referring to FIG. 1, the galley cart 10 includes a cover member 62 at least partially made of molded plastic to cover the upper portion 18 of the body 14. The cover member 62 is defining a substantially planar work area 66 defined by a peripheral frame 70 configured to prevent objects to slide off the upper portion 18 of the body 14. The work area 66 is equipped to receive containers 150, 160 thereon.
The bottom portion 30 rests on a wheelbase 80 adapted to pivotally secure thereto a set of four (4) of caster wheels 84. Two pedals 88 are also pivotally secured to the wheelbase 80 to selectively lock or unlock the caster wheels 84 to immobilize the galley cart 10 when required.
An optional tablet 100 is optionally secured inside the body 14, adjacent to the upper portion 18. The tablet 100 is moveable between a closed position 104 and an opened position (not illustrated). The tablet 100, in the closed position 104, is housed in the body 14 and does not extend outside the body 14 to fit in a corresponding galley (not illustrated). A locking mechanism 112 prevents the tablet 100 to extend when undesired. A handle (not visible in the Figures) is affixed to, or built in the extendable tablet 100 and is more accessible when the extendable tablet 100 is slightly extended.
It can be appreciated from FIG. 1 D) the work area 66 is bordered with the peripheral frame 70 to help secure the goods located on the work area 66 of the cart 10. The peripheral frame 70 is embodied as an extrusion 120 made of aluminum or plastic material. The peripheral frame 70, in the present embodiment, is shaped to provide a plurality of container-supporting portions 74 that includes a low support portion 130, a low contour portion 134, a high support portion 138 and a high contour portion 142. The low support 130 is contoured by the low contour portion 134 on the four sides of the galley 10. Hence, a first size container 150 can be removably supported by the upper portion 18 and laterally secured by the low contour portion 134 on the four sides 146.1, 146.2, 146.3 and 146.4 of the galley 10. Generally, first size containers 150 includes first size supports 154 disposed on its low lateral edges 168. The supports 154 are supported by the low support portion 130. One can appreciate the plurality of container-supporting portions are embodied as a plurality of container-supporting levels above the work area 66.
In reference now to FIG. 3 and FIG. 4, it is depicted the high support portion 138 of the peripheral frame 70 is contoured by the high contour portion 142 on three sides of the galley 10. Hence, a second size container 160, longer than the first size container 150, extending 172 beyond the longitudinal length 42 of the cart 10, is required to extend over the peripheral frame 70 to rest, on the high support portion 138. The second size container 160 can hence be removably supported by the upper portion 18 and laterally secured by the high contour portion 142 on three sides 146.1, 146.2 and 146.3 of the cart 10.
In one configuration, a single side 146 of the high contour portion 142 is removed and the contour is leveled 176 to the height of the high support portion 138. In the illustrated embodiment, the rear high contour portion 142 at the rear of the body 14 has been reduced/removed. This way, the second size container 160, longer than the longitudinal length 42 of the work area 66, can extend beyond the peripheral frame 70 while be housed along and horizontally secured on three sides 146.1, 146.2 and 146.3 of the cart 10. Generally, second size containers 160 include second size supports 164 thereon disposed on its low lateral edges 168. The supports 164 are sized and designed to contact the high support portion 138 to secure the second size container 160 on the cart 10.
One can appreciate in the illustrated embodiments that the low support portion 130 is substantially levelled with an upper surface of the work area 66, the low contour portion 134 is substantially perpendicular to the upper surface of the work area 66, the high support portion 138 is substantially perpendicular to low contour portion 134 and generally aligned with a virtual vertical projection of the panel 34 and the high contour portion 142 is substantially perpendicular to high support portion 138 and substantially aligned with a virtual vertical projection of the panel 34. Connections between adjacent supports and contour portions preferably include an intervening radius.
The first size container 150 is laterally bordered and held by the low contour portion 134 over its four sides, while the second size container 160 is laterally bordered and held by the high contour portion 142 over three of the four sides. In the latter situation, the second size container 138 can be slidably mounted on the high support portion 138 and be pushed and slide rearward to allow access to the volume under the second size container 160 to the work area 66. Alternatively, the second size container 160 can be equipped with a locking mechanism holding it in a desired position on its container-supporting portion 74. Referring more precisely to FIG. 3 D), it can be seen the high support portion 138 is a little higher than the bottom surface 180 of the second size container 160.
The illustrated cart 10, in reference with FIG. 4, includes a pair of junction members 38 disposed vertically between the rear transversal portion 48 and the right longitudinal portion 22 and between the rear transversal portion 48 and the left longitudinal portion 26, the junction members 38 including an upper portion 92 thereof transitioning between the uppermost portion 144 of the peripheral frame 70 and a height of the high support portion 138.
It can be seen in FIG. 5, FIG. 6 and FIG. 7 the handle 116 is used to move and steer the cart 10. The handle 116 is also retaining the second size container 160 on its forward portion used as a section of the high contour portion 142.
FIG. 8 and FIG. 9 are illustrating from a different angle the cooperation between the first size container 150 and the peripheral frame 70 of the cart 10. It is also possible to appreciate from a different angle the cooperation between the second size container 160 and the peripheral frame 70 of the cart 10.
Finally, in reference with FIG. 7, FIG. 12, FIG. 13 and FIG. 14, the tablet 100 can be replaced by, or be used as an ice tray 200 for cooling the content of the cart 10. Cold medium, such a dry ice, can be added in the tablet 100 (that can include a cavity and could alternatively be referred to as a drawer 204) and cold is going to naturally get down 208 through cooling openings 212 performed in the tablet compartment 216 floor 220 between the upper portion 18. A dry-ice pack 224 can replace the tablet 100 or the drawer 204.
