Patent Application
20080116318
The invention relates generally to extendable and retractable devices related to the management of food service.
Ideally, when a business needs to serve food and beverages, the customers are conveniently located at tables, a large kitchen with a staff is located nearby, and there is ample space to organize and plan the food service, and to prepare the food. However, there are many scenarios in which this is not the case and in which information regarding the food service must be readily available to staff operating in very limited space conditions. An example is a galley on an airline, bus, or ship. On an airline, for example, food and beverages are generally served to customers. There are obstacles to overcome when serving such food and beverages, including the very limited space available for the serving personnel, food, and heating and chilling equipment for the food. Maneuvering in such conditions is difficult for the staff. Moreover, galley aisles need to be kept clear for safety reasons. Food is often served on serving carts to passengers. These carts need to be properly outfitted and stocked, and, often, the cart location, cart inventory, cart food temperature, and the last sanitization of the cart needs to be tracked. Food service information needs to be available to the staff without disrupting the food service itself, creating a safety hazard by blocking an aisle, or taking up much needed space in the galley. It can thus be seen that there is a need for an extendable and retractable control device, which can provide information to staff operating in limited space, and can be stowed out of the staff's way in a wall aperture when not in use.
In an embodiment, an extendable and retractable assembly is provided. The assembly comprises a mounting member attached to a support structure disposed inside an aperture in a wall. The assembly has a telescoping arm with a first and a second end. The first end of the telescoping arm is attached to the mounting member and the second end of the telescoping arm is attached to a rotation member. A control device is connected to the second end of the telescoping arm by the rotation member. When the telescoping arm is extended such that the control device is no longer stowed inside the aperture in the wall, the control device can rotate at least partially around an axis substantially perpendicular to the telescoping arm. The invention does not get in the way of food service operations yet is quickly accessible when needed. These and other advantages of the invention will be apparent from the description of the invention provided herein.
The invention is generally directed to a retractable and extendable control device assembly that can be stowed and retrieved from a wall aperture. The following examples depict the invention utilized in the galley of an aircraft and more particularly as part of an on-board food management system that allows a user to display data and enter data related to food service on the aircraft. The invention, however, is not limited to use in an aircraft galley or to a food management system; it is directed toward use in any environment in which users must interact with a control device in limited space. The following examples further illustrate the invention but, of course, should not be construed as in any way limiting its scope.
Referring to
In one embodiment, the telescoping arm 11 has first 15, second 16, and third 17 sections as shown in
The control device 14 is connected to the second end 13 of the telescoping arm 11 by the rotation member 21. The rotation member 21 may be connected to the third section 17. In the embodiment shown in
The mounting member 18 is mountable to a support structure 28. In the particular embodiment shown in
When the telescoping arm 11 is extended such that the control device 14 is no longer stowed inside the aperture 29 in the wall 30, the control device 14 can rotate at least partially around an axis 31 that is substantially perpendicular to the telescoping arm 11. In the preferred embodiment the control device 14 can rotate substantially ninety degrees around the axis 31.
In a preferred embodiment, the housing 22 of the control device 14 is connected to the third section 17 by the rotation member 21. The housing 22 can rotate at least partially around the axis 31 that is substantially perpendicular to the telescoping arm 11 when the second 16 and third 17 sections are extended such that the housing 22 is not disposed inside the aperture 29 in the wall 30 of the aircraft. The rotation member 21 may be any mechanism or assembly that is suitable for allowing rotation of the housing 22 of the control device 14 about the axis 31.
The housing 22 has a top surface 23 and a bottom surface 24. The rotation member 21 is disposed on the top surface 23. In the preferred embodiment, the rotation member is disposed on the top surface 23 substantially near a midpoint 24 of the distance between the right side 25 and left side 26 of the control device 14. This placement allows the control device 14 to rotation in place. The rotation member 21 may be disposed elsewhere on the housing 22 in other embodiments.
The telescoping arm 11 can be retracted so that the control device 14 is substantially flush to the wall 30. In the embodiment shown in
A handle 32 is disposed on the housing 22 of the control device 14 for actuating extension of the second section 16 from and retraction into the first interior 19 of the first section 15 and for actuating extension of the third section 17 from and retraction into the second interior 20 of the second section 16. The handle 32 is this embodiment is a finger pull handle. Other types of handles could be used in other embodiments.
The assembly may be substantially stowed inside the aperture 29 when the telescoping arm 11 is in a retracted position and the control device 14 is substantially parallel with the telescoping arm 11. The plane in which the housing 22 is disposed may be substantially aligned with the plane in which the telescoping arm 11 is disposed when the housing 22 is stowed inside the aperture 29. In the embodiment shown in
