2. Title:

Transport trolley system for manual storage, relocation and retrieval.

3. Area of application:

The invention relates to a modular transport trolley system with which storage, transfer and retrieval processes can be carried out particularly efficiently.

4. Preliminary remarks on the state of the art:

In warehouse handling processes, platform trolleys and so-called tiered trolleys are generally used in a large number of different designs. The trolleys are rigid. The goods to be transported can be placed directly on the platform or tiers, stacked on top of them, or placed, layered or poured into containers.

5. State of the art and disadvantages of the state of the art:

5.1 Platform trolleys are not suitable for placing a large number of different containers on them and picking them according to certain sorting criteria.

5.2 Conventional tiered trolleys have the disadvantage that they cannot be converted to different container sizes quickly enough, or loading capacity is lost if different sized containers are placed on the individual tiers for filling.

5.3 In order to be able to quickly place goods into or take them out of containers on conventional tiered trolleys, the clearance between the upper edge of the container and the lower edge of the tier above it must be large enough, which leads to capacity losses.

5.4 If the clearance is small, it is not possible to see into the containers properly and loading bulky goods in particular becomes more difficult and time-consuming.

5.5 Unused shelf trolleys take up a lot of space. This is particularly disadvantageous when handling volumes fluctuate greatly or when goods that have been prepared for dispatch have to be temporarily stored on the trolley for a few days at intervals for various reasons.

5.6 Handles of the known types of strollers have a height that cannot be adjusted to the body size.

6. Object of the invention:

The object of the invention is to create a transport trolley system which can be flexibly adapted to different container sizes and different transport and handling tasks in such a way that, by observing ergonomic principles, i.e. by making work easier, faster and more efficient work with this trolley is possible and at the same time other advantages are achieved, such as space-saving parking of empty trolleys.

7. Solution to the task:

The task is solved by placing a stand frame, on which support elements, handles for pushing or pulling, clipboards for holding order papers, a terminal or containers of all kinds can be quickly and easily attached or hung at different heights, on a specially shaped, e.g. trapezoidal, chassis in such a way that the chassis of empty and dismantled transport trolleys can be pushed into one another to save space.

8. Advantages of the invention:

8.1 Empty and dismantled transport racks can be stored in a space-saving manner by pushing them into each other.

8.2 The height, inclination and positioning of the support elements relative to the stand frame can be adjusted so that the trolley can be quickly adapted to changing container sizes and tasks.

8.3 By placing containers at an angle on top of each other, goods can be removed or filled extremely quickly.

8.4 When picking, boxes placed at an angle on top of each other allow the goods to be placed immediately into the shipping container provided, i.e. the goods do not have to be driven to a packing station and packed there, as was previously the case.

8.5 By using support elements of different lengths and special supports, containers, goods and boxes can not only be arranged at an angle one above the other, but even arranged at an angle in a terraced or stepped manner one above the other, which improves the overview when inserting certain goods.

8.6 Support elements designed as telescopic rails enable a trolley to be loaded with containers in a particularly compact manner while still allowing access to each individual container, as it can be pulled forward.

8.7 Individual handles can be attached to the support frame at a height corresponding to the height of the respective employee.

·

8.8 Clipboard supports or terminal supports can be installed at eye level and designed to be foldable or pivotable so that the insertion of goods into the container behind or below them is not hindered.

8.9 The upright frame and chassis may be arranged in such a way that the container openings are either transverse or longitudinal to the direction of travel.

8.10 Support elements may be designed with hinges so that they can be folded up after the containers standing on them have been removed, which has advantages for emptying the containers underneath and for space-saving storage.

8.11 Support elements can be arranged so that the container placed on them can be positioned between the columns of the support frame or in front of them in any inclined position. This makes gripping and visual work during filling and emptying easier.

8.12 Stand frames can be placed at an angle on the chassis, which allows a stepped arrangement for certain containers and thus advantageous handling for certain transport or shipping goods, e.g. sorting sets together.

8.13 The stand frame can be designed as a single-column stand, which leads to several vehicle variants with special advantages for particularly light goods to be transported.

9. Description of embodiments :

Figure 1:

Figure 1 shows side view (a), front view (b) and top view section (c) of an embodiment of this modular transport system.
A trapezoidal chassis (F) sits on 2 fixed castors (BR) and 2 swivel castors (LR) or 4 swivel castors, of which at least 2 swivel castors can be temporarily or permanently locked in the direction of travel.

When the load is light, the chassis can be left open on one side or closed with a connecting profile (VP) slightly above the frame level, so that several wagons can be pushed into one another when dismantled and empty, see dashed lines (F').

A stand frame (St) can be welded or plugged onto the chassis (F), whereby, depending on the respective operating conditions, the frame can be attached closer to the fixed castors, as shown in sketch a, in the middle or also near the swivel castors, whereby the clear distance between the stands changes.

Elements that serve different purposes can now be inserted or hung on the stand frames, which are perforated on one, two, three or four sides, e.g.

Inclined support 1 (TR1) to allow a container or box (K1) to be placed as low as possible between the upright supports and at a sufficient angle for filling or emptying. Transport goods can also be placed directly on the support instead of containers.
Beam 2 (TR2) with the same purpose, always to be arranged above beam type 1 for holding stored goods, containers or boxes (K2) between the upright supports.

Beam 3 (TR3) is positioned so far forward that containers or cartons (K3) placed on it may be wider than the clear width between the supports.

Handle elements (G 1 + G2) can be attached at any height to make it easy to push or pull the trolley. The vertical handle position is more ergonomic than the usual horizontally arranged handle bars.

In an analogous manner, a number of functional elements can be quickly attached to the perforated stand frame at any height, i.e. optimally adapted to the function, and removed just as quickly, e.g.

- Rearview mirror - Forward mirror

- clipboard - mobile terminal

- Notebook
etc.

The elements can be rigid, i.e. only adjustable in height, or they can be swivelled, folded or have a gooseneck design that can be positioned as desired.

Figure 2:

Figure 2 shows a side view of a transport trolley in which the containers/cartons placed on horizontally and/or obliquely arranged support elements are arranged in a step-like manner by inclining the stand frame, so that a more or less large gripping opening is released depending on the inclination or double inclination.

Figure 3:

Figure 3 shows a side view of a trolley in which the support elements are provided as telescopic pull-out supports or similarly extendable horizontal and/or inclined elements, so that containers, boxes or loads can be pulled forward as desired for filling or emptying.

Figure 4:

Figure 4 shows the side view of a transport trolley with foldable support elements, so that, for example, container 1 (B1) is filled first, then container 2 (B2), etc. The raised support elements do not hinder filling. When a container is full, the support element above it can be folded down and another container, in this case (B3), can be placed on top. The emptying process takes place in the reverse order.

Figure 5:

Figure 5 shows the side view with a partial section of a tube of a transport trolley with a single or double stand that can be lifted up, whereby the stand element lifted by the hoist can be equipped with any support elements. The liftable stand elements move telescopically over the columns made of a matching profile that are attached to the chassis.

Figure 6:

Figure 6 shows the top view of several dismantled empty chassis type 1 placed one inside the other in the direction of travel, with the frame (St) cut away.

Figure 7:

Figure 7 shows, in an analogous manner, the top view of several dismantled empty chassis of type 2 placed inside one another transversely to the direction of travel, whereby chassis with 4 swivel castors that can also be locked transversely to the direction of travel are required for placing the transport trolley type 2 inside one another. This type has advantages for driving in narrow aisles and for special purposes.

Figure 8:

Figure 8 shows top and side view sections of the chassis in a particularly narrow shape, which makes it easier to push the empty transport trolleys together.

Figure 9:

Figure 9 shows a perspective sketch of a transport vehicle according to Figure 7. It is particularly advantageous to equip this type of vehicle with support elements according to Figure 3, e.g. with perforated sheet support and slightly inwardly inclined supports.

Figure 10:

Figure 10 shows a perspective sketch of a transport trolley according to Figure 7 with only one stand, which is perforated on all four sides. This design is particularly suitable for extremely light transport goods or for special purposes, as well as for almost horizontal or inclined support elements.

Figure 11:

Figure 11 shows the top view of the wagons according to Figure 10; the dashed lines show how support elements and transport goods can be placed lengthwise to the direction of travel.

Figure 12:

Figure 12 shows a plan view of a wagon according to Figure 10; the dashed lines show how smaller support elements can be attached transversely to the direction of travel and how containers can be placed on both sides.

Figure 13:

Figure 13 shows a perspective view of an embodiment according to Figure 1 as a picking trolley for immediate picking in shipping containers, with attachable clipboard K pivotable about joint G and with carrier variant A for boxes that fit between the upright columns

and carrier variant B for wider boxes that must be placed in front of the upright columns.

Figure 14:

Figure 14 shows in (a) a half plan view of the chassis and in (b) the side view of an embodiment for picking into extra large shipping boxes, consoles K4 and K2, with console K3 for accommodating a smaller box K3 on the rear and intermediate storage console K1 (see Figure 14 c) and front view of the same embodiment in Figure 14(d).

Figure 15:

Figure 15 shows a front view (a) and a top view (b) and a perspective sketch (c) of an embodiment for order picking in two shipping containers with height-adjustable and laterally movable consoles for intermediate shelves above them, which allow particularly dense stacking or even stacking according to plan (light over heavy; soft over hard, etc.) during order picking.
