Definitions
- the invention relates to a fork and a logistic vehicle for it, as described in claims 1 and 13.
- Fork tines are usually made from solid material, with the back of the fork, the fork knee and the fork blade being forged from one block. Fastening means, in particular eyelets and hooks, are fastened to the fork back and are preferably welded to the fork back.
- Such fork tines made of solid material have the major disadvantage that they are very heavy, which means that a logistics vehicle with correspondingly large dimensions is required so that it does not tip over.
- a fork arm is known from EP 0739854 A1, in which at least part of the fork arm, in particular the back of the fork, the fork knee or the fork blade, consists of several individual adjacent layers. The multiple layers are welded together to form the shape of the fork tine.
- the disadvantage here is that deformation can occur due to the high heat exposure caused by the welding process.
- EP 0 739 854 A1 proposes creating a fork formed from several layers, which can be produced inexpensively with little energy expenditure and using universal tools with the most varied of shapes and dimensions, even in the smallest lot sizes.
- discs that are easy to produce are manufactured as parts of the forks, which are connected to one another in an immovable manner by fastening elements such as screws, rivets or pins or by gluing or welding.
- the forks produced by a large number of individual disks have a similar weight to e.g. B. existing forks made of solid material, produced in the forging process.
- DE 102019102846 A1 describes a fork arm, in particular for industrial trucks, which is attached or can be attached to a carrier guided by a lifting device.
- the load handling device which is formed by the fork back and the fork knee, is formed from at least two discs or profiles, each spaced apart from one another, which are connected to the carrier on the one hand and at least areas of a fork blade consisting of at least one longitudinal hollow profile on the other are included, wherein the longitudinal hollow profile are firmly connected to the discs.
- EP 3659961 A1 discloses a fork, in particular a fork blade, for an industrial vehicle such as a forklift and a method for its production.
- the fork comprises an elongate body portion, a fork tip and a fork end which are connected, in particular welded, to one another to form the fork, in particular the fork blade.
- the elongate body portion may be of any length and may have multiple lumens.
- DE 4315891 C1 discloses a fork arm for forklift vehicles which is approximately L-shaped.
- the fork blade and the fork back consist of profile or bar sections, with a reinforcement being welded into the fork blade and a fork tip made of a forged part at the end of the fork blade is welded on.
- the disadvantage of the prior art described above is that the production of the fork is very expensive and the high heat when welding the individual parts can lead to a delay that can lead to the point that the fork can no longer be used.
- a further disadvantage is that the production, in particular the welding of the parts, can only be carried out by appropriately trained specialists, in particular welders, which drives up the production costs.
- the rapidly growing market for automated logistics vehicles, especially self-propelled forklifts, is changing the requirements for the very heavy forks that are still standard today.
- the object of the invention is therefore to create a fork arm and a logistics vehicle for this, with which on the one hand the above-mentioned disadvantages are avoided and on the other hand they can be produced with little energy expenditure and maximum possible flexibility in shape and dimensions in the smallest lot sizes.
- the fork tine is characterized in that the fork blade is formed from a top layer and a back layer to form a cavity, which are connected to one another, in particular screwed, by means of fastening means, in particular screws.
- the load capacity of the forks can be influenced due to the fasteners or reinforcement elements used or used, i.e. more or fewer fasteners or
- Reinforcing elements a higher or lower load is achieved. This makes it possible to adapt to the loads to be lifted, which has an effect on the manufacturing costs and the weight of the forks.
- top layer and the back layer are preferably made of thin-walled, straight sheet metal formed using the cold bending process, so that the shape of the fork tine can be easily adjusted. Customer requests can thus be implemented quickly and easily.
- a design is advantageous in which the back of the fork is also formed by a cover layer and a back layer, which are connected to one another, in particular screwed, by means of fastening means, in particular screws. This in turn creates a cavity between the two elements, as a result of which a considerable weight saving is achieved with a high load capacity and sufficient space remains for the electronics integrated into the fork, in particular sensors.
- cover layer is formed from a U-shaped folded sheet metal and the back layer is formed from a planar sheet.
- a bending process in particular a cold bending process, only has to be applied to one part or element, namely the cover layer, for the production of the fork prongs, which saves on production costs and production time.
- inverted structure i.e. a planar top layer and a U-shaped backing layer, in which case it has proven to be advantageous that the planar part is not positioned between the edged side parts of the backing layer, but on top of it rests on the end faces of the side parts.
- An embodiment is also advantageous in which the cover layer and the back layer are formed from a plate folded in a U-shape, in particular a steel plate. It is possible that one of the two U-shaped parts is designed in such a way that it can be arranged between the edged side parts of the other element or that the top layer and the back layer are joined together via the front edges of the side parts, which means that a shorter edge length is required , which increases rigidity.
- An embodiment is advantageous in which reinforcing elements are arranged in the cavity between the cover layer and the back layer. As a result, the load capacity or load capacity of the fork tine can be increased with little effort and, above all, a small increase in weight.
- the load capacity can be increased or decreased by changing the distance or distance between the top and back layer or by changing the sheet thickness.
- the reinforcement elements can first be positioned accordingly on the back layer, for example, and then the top layer can be placed on top and screwed together.
- a structure in which the reinforcement elements accommodate the fastening means is advantageous.
- an embodiment is also advantageous in which the cover layer of the back of the fork and the fork blade has indentations for receiving the fastening means, in particular the screw head, to form a flat surface.
- This ensures that no disruptive fasteners protrude beyond the surface of the top layer, so that when the fork tine is positioned, it can simply be pushed into a load carrier or pallet, in particular a Euro pallet. This means that the top layer cannot get caught when the load or pallet is picked up, as the surface is flat.
- a design is advantageous in which the top layer of the fork back and the fork blade has additional bores for the attachment of additional aids. This makes it possible, for example, that some or all holes with Threads are provided so that appropriate tools such as eyelets or rings that have a threaded element can be screwed in. This also allows the fork to be easily attached to a logistics vehicle.
- a design is advantageous in which the fork knee is designed to correspond to the cavity and can be inserted over a partial area of the cavity of the fork back and the fork blade.
- the arrangement of the mounting holes for the fork knee be standardized. It is possible that the arrangement of the mounting holes for the back of the fork and the fork blade can be the same or different.
- the fork knee can be attached to the fork leaf and/or fork back
- the fork knee has bores for receiving the fastening means.
- these holes are formed on the top layer and back layer of the fork blade and the fork back, so that the components can be connected to form a unit.
- an L-shaped fork tine with a low weight is created, which can replace the heavy fork tines from the prior art with an approximately constant load.
- the modular design makes it possible to produce a wide variety of fork tines for different payloads easily and inexpensively.
- a design is advantageous in which the fork knee has a joint for folding up the fork leaf, the joint preferably being hydraulically or electrically controllable. This makes it possible that when not required Fork tine the fork blade can be folded up, so that a space-saving movement of a logistics vehicle is made possible.
- a design is advantageous in which sensors, lines and electronic control units are arranged in the cavity of the fork blade and the fork back, which can be connected to a logistics vehicle via a connector on the fork back.
- the fork can be adapted or equipped and expanded to meet today's requirements, in particular the specifications of Industry 4.0. Subsequent expansion is also possible, since only certain parts have to be mechanically reworked or replaced.
- a logistics vehicle in particular a self-propelled logistics vehicle, comprising at least one base vehicle with a lifting device for transporting loads, preferably on a load carrier or a pallet, in particular a Euro pallet, in which a fork arm according to one of the claims is attached to the lifting device 1 to 13 is attached.

- the fork back 3 is also constructed modularly by a cover layer 10 and a back layer, which are connected or screwed to one another via fastening means 12, in particular screws 12a.
- the fork back 3 and the fork blade 5 are made from thin-walled, straight sheet metal that is preferably formed using the cold bending process, with one or more reinforcing elements 13, in particular metal spacers, which can also consist of metal alloys, being arranged in the vertical fork blade 5 and in the horizontal fork back.
- the reinforcement elements preferably have bores through which the fastening means 12, in particular screws 12a, run.
- the cavity 9 is formed in the fork blade 5 and in the fork back 3, which greatly contributes to saving the weight of the fork 1 and offers space for electronics and/or sensors 14 and wiring.
- the stress distribution with tension and pressure zones and the neutral axis in the fork 1 is optimally utilized.
- the compact fork knee 4 also further favors the relationship between deflection and the stresses that occur.

- corresponding threads to be provided in the bores in the fork knee 4 corresponding to the fastening means 12, so that the top layer 10 and the back layer 11 are fastened directly to the fork knee 4 independently of one another.
- the fork knee 4, the fork blade 5 and the fork back 3 can be designed for the maximum stress amplitude that occurs locally and thus allow different sheet metal materials and material thicknesses to be used in an optimized way for the respective load without sacrificing to take the weldability of the materials into account, i.e. that the top layer 10 and the back layer 11 as well as the fork knee 4 are made of different materials, whereby a combination of materials can be used that does not have to be weldable, since the fork tine 1 is completely without Welded connections is established.
- the fork blade 5 and/or the fork back 3 is constructed in such a way that at least one element, in particular the top layer 10, is U-shaped, with the side parts 15 being produced using a bending process, as can be seen better in FIG. 4 . From this it can be seen that the rear layer 11 is accommodated between the side parts 15, with the hollow space 9 being formed between the top layer 10 and the rear layer. It is of course possible for the backing to rest on the end faces of the side parts 15, which in turn forms the cavity 9.
