Patents Act 1990 COMPLETE SPECIFICATION Standard Patent Applicant(s): Roland Muller CNC Fertigungstechnik Invention Title: LIFTING MEANS FOR MOVING CONTAINERS VERTICALLY, IN PARTICULAR FOR MOVING TROLLEYS The following statement is a full description of this invention, including the best method for performing it known to me/us: P77384AU PatSetFiling Application 20G8-3-28 oc (S) 00 Lifting means for moving containers vertically, in particular for moving trolleys t, SThe present invention relates to a lifting device for moving containers vertically, in 00 s particular for moving trolleys, with a controllable, height-adjustable elevating table.
(N
t The means can be used in many different fields of application. The preferred field of application is lifting trolleys. Trolleys are particularly used in the catering field, for example in aviation. There, they are used on board airplanes for transporting food, 00 10 drinks, tax-free products and such like. To load and unload trolleys, it is necessary to raise and lower them. The lifting means can be loaded with a plurality of trolleys.
A device is known from DE 298 13 600 U1 which has a holder for a container, the height of which can be continuously adjusted by means of an electric linear drive motor. The disadvantageous of this device is that, on account of its electric motor drive, it cannot be used, or only with restrictions in wet areas.
Moreover, DE 29 22 955 Al describes a height-adjustable working means which enables an adjustment to the conditions of the particular user. The height is adjusted by means of an elevating spindle driven by a drive motor.
The object of the invention is to provide a lifting means of the initially described type which enables a continuously adjustable vertical motion for the application, and which can be used in wet areas without restrictions. The lifting of the containers is intended to enable the operating personnel to work in a healthy and ergonomic manner which, in particular, eliminates all bending over.
This object of the invention is solved by a means with the features of claim 1.
Advantageous embodiments are stated in the subclaims.
Further objects of the application are combinations of features in which the individual features described are combined optionally with one another.
00 O The lifting means has a basic device open on two opposite sides which is arranged on a ring foot which can be rotated through 3600. The elevating table can be moved up and down in the basic device by means of guides arranged vertically on both 00 5 sides. It is driven by at least one pneumatic cylinder arranged at the side, the smooth (,i motion of which is ensured by the toothed belt drives arranged on both sides, which are coupled by means of a synchronizing shaft. A particularly smooth motion is achieved by the arrangement of two pneumatic cylinders mounted on opposite sides.
00 10 In an advantageous embodiment of the lifting means, each of the guides has four Srollers arranged on both sides of the elevating table running on angled guide plates, which are connected to the basic device. This ensures jolt-free vertical motion.
Moreover, it is possible for the elevating table to have a surface for holding the containers, which are to be moved, to which hinge-mounted loading ramp plates are attached, which automatically fold down when the elevating table is in its lowest position in order to enable the containers to be run in without having to negotiate a step, and which fold up when the elevating table rises. The path of the containers when they are run in is guided by a suitable contour of the side parts.
Another advantageous embodiment provides for the arrangement of actuating elements on both sides of the basic device, which can be used to actuate the valve control of the pneumatic cylinder thus enabling easy operation by both left and right-handers.
An adjustable safety restraint is preferably arranged on the top surface of the elevating table to hold the containers in position during the upward and downward motions of the elevating table.
The invention is described in more detail in the following by means of an embodiment.
The accompanying drawings show: Figure 1 An overall view, with containers, in which the elevating table is in its upper position.
00 Figure 2 An overall view of the arrangement, in which the elevating table
O
0is in its lower position.
Figure 3 An exploded view of the arrangement, and Figure 4 Two views of the open device.
00 In the overall view as shown in Figure 1, the elevating table 5 is in the upper position and is filled with three containers 19. In the view shown, trolleys are presented as containers 19. The figures show a version for receiving three trolleys, while versions for receiving a higher number of trolleys are also possible. The lifting 00 10 device consists of a compact base unit made of high-grade steel, and presenting two Sside parts 1, their covers 2 as well as a roof 3 and a casing bottom 10. The base unit is fastened to a ring foot 4 which enables a rotation by 3600. An elevating table 5 is located at the centre of the lifting device. The elevating table is used for receiving the containers 19.
In Figure 2, the elevating table 5 is in the unloaded condition and in its bottom position. Ramp plates 16 are located at the front side and at the rear side of the elevating table 5. These ramp sheet plates are folded out by the contour of the side parts 1 when the elevating table 5 moves down. They fold back into the vertical position when the elevating table 5 is moved upwards. They allow the stepless running motion of the containers 19 onto the elevating table Figure 3 shows the component parts of the base unit including the covers 2, the roof 2, and the ring foot 4. The lifting device operates using controlled compressed air.
The compressed-air connection 14 is located at the roof 3. At the side parts 2, actuating elements 15 are located for valve control, and they are used for controlling the pneumatic cylinders, and for bringing about the upward and downward motions of the elevating table 5. This allows the left-hand or right-hand operator control of the lifting device. The elevating table 5 stops as soon as one of the actuating elements 15 is released. Furthermore, two handles 18 are installed each at the covers 2 of the side parts 1. They enable the lifting device to be rotated without restrictions manually by 360' around its own axis, and to position it individually for loading and unloading the containers 19.
0 Figure 4 explains the driving mechanism. The elevating table 5 is moved by means
O
Sof the two pneumatic cylinders 6 which are installed in parallel at the side. The pistons of the pneumatic cylinder 6 are connected to the elevating table 5 by means of a location sheet plate 7 on both sides. Toothed belts 8 are also fastened on both 00 5 sides at this location sheet plate 7. The toothed belts 8 are guided by one toothed belt wheel 9.1 each at the top of the casing and one toothed belt wheel 9.2 at the bottom of the casing over the casing's entire height. The synchronism between the two synchronous belt drives is guaranteed by a synchronizing shaft 11 linking the two upper toothed belt wheels 9.1. Four rollers 12 are located on both sides at the elevating table 5, are guided at angled guide sheet metal plates 13, and allow jolt- Sfree vertical motion. A safety restraint 17 is mounted at the location sheet plates 7 of the elevating table 5, and prevents the containers 19 from falling out when the elevating table 5 is lifted. The safety restraint 17 is adjustable individually for different containers 19, and folds up automatically when the elevating table 5 is moved down. This is ensured by two screws which are not shown in the side part 1, but along which the safety restraint 17 slides during the lifting motion. When the elevating table 5 is lifted, the safety restraint 17 folds down by its own weight again, thus securing the containers 19.
