    Fins for container hooks. Unlike the positioning fins commonly used for this application, which are rigid elements, the fins object of the present invention consist of a new type of fins, which behave in a rigid manner in normal service, but which yield elastically to impacts and overloads, recovering later their way of working. This flexibility is achieved by two ways, which only affect the fin itself, not its connection to the harness or its possible operation. Namely: use of elastic materials and use of stable geometries before service loads but deforming easily with impacts. (Machine-translation by Google Translate, not legally binding)

    ELASTIC FINS FOR CONTAINER HITCHES.
    SECTOR OF THE TECHNIQUE
    Knowledge area: Mechanical Engineering, Mechanism Design, Materials Technology and Lifting, Transportation and Maintenance Equipment sections.
    Industrial activity: multimodal transport, container transport, lashing and container handling.
    STATE OF THE TECHNIQUE
    Most of the solid goods that move around the world are distributed by containers, transported by ship, road or rail. The containers are carved for lifting, loading, unloading and stacking using hooks equipped with simple locking mechanisms at the ends. The usual term for the hitch is the English word "spreader" and the bolts are latches known as "twistlocks" ("twist locks"). See figure 1.
    In principle, the trenching operation is very simple, just by positioning the hitch just above the container, in contact with its upper face and then turning the latches with which the hitch is produced. However, the part that protrudes from the latches are lugs whose size (of a few centimeters) is very small compared to the dimensions of the container (six or twelve meters the most common). They are not normally outside the visual field of the grower and the operation is carried out five, twenty or more meters away from the grower. See figure 2.
    Consequently, it is essential to have a mouthpiece system that guides the hooker over the container, ensuring that the corners of both coincide so that the pin fits right into the small socket of the container prepared for this purpose, also called a corner.
    The usual mouthpiece system is the one made by fins, better known as "flippers". Mouthpieces in inclined steel sheet that are arranged in the corners or sides of the hook and penniten save small misalignments.
    It is common for these fins to be foldable, with a mouthpiece position for the carving and another folded for the stacking of the container. This feature does not affect the idea proposed in this patent application, which can be used for both retractable and fixed fins.
    It is important at this time to mention the dimensions and speeds with which
    works The standard container can be between a couple of tons (empty tare) and more than eighty. The weight of the hitch is also in the range of tons. The hitch descends on the load from a height of several meters, sometimes vertically and more often at an angle. A mganchador may be performing trenching operations every two minutes, moving the load to more than thirty meters high and fifty meters in horizontal projection. That is, we are facing an operation where the search for productivity leads to high speeds and very low trenching times. . The grower, to speed up the production, of}} .: take the hitch following a curve at great speed, instead of stabilizing it above the load and slowly lowering it vertically. This causes the fins to take heavy blows with the containers, both laterally and from below. See figures 3 and 4.
    The consequences of the blows result in damage to the containers, the hooker, the cargo, risks to people and, most commonly, the dents or breakage of the fins, with the consequent corrective maintenance operation and the possible loss of earnings when a critical machine is affected.
    Figure 5 shows a fin in the mouth position. In this case, it is not integral but with three pieces screwed together. In any case, everything runs in steel, both the wide part that serves as a guide. the high part that holds the fin to the hook (motorized to move it at a distance), like the central part or crossbow that connects both.
    Figure 6 shows different models of fins. All rigid, made of steel.
    When reviewing the previous literature and patents, it is observed that the problem of blows has been treated before, but from the perspective of the drive.
    This is the case of patent E08774959 of July 10, 2008 "Positioner for container grip" (Spanish version EP 2188202 of November 28, 2012), which claims the use of a shock absorber clutch coupled to a coupled polygonal shaft yet
    polygonal elastic seat. This refers to the axis whose rotation causes the flap of the flap, something that we do not treat at all in our idea, referred to the fin itself.
    S 10 Patents on modelm are frequent; of hooks, stackers or latch drives and fin drives. As an example, US patent 201110140470 Al "Spreader with flipper arm drive" by R. A. Milis et al., Which, as its title indicates, refers to the actuation of the fin. There is also a wide variety of fin gcometers, as shown in Figure 6. However, in all cases it has been assumed that the embocado fin should be a rigid element, made in practice in steel, either integral, welded or bolted but always creating a single rigid kinematic link.
    DESCRIPTION OF THE INVENTION
    The technical prejudice that is overcome by this invention is the idea that: the fins for container hooks must be a rigid element.
    lS The present invention consists of a new type of fins for container hooks provided with significant flexibility, in such a way that they yield to impacts. This flexibility is acquired, not because of its connection to the coupling or its possible operation, but because of the combination of:
    twenty Use of elastic materials: rubber, rubber, Teflon, textile, elastomeric composite materials and the like, either of homogeneous composition or reinforced with metal fibers or any other type.
    2S Modification of the fin geometry. Use of plates (leaf springs) instead of integral plates, in such a way as to facilitate the defonnación before impacts. Use of profiles, open or closed, arranged to achieve the right combination of rigidity in service, cushioning and flexibility against impacts.
    30 It is not always essential to use special profiles or geometries to achieve the desired effect, but it will depend on the load to be transported, the weight of the hitch and the service speed. In certain applications, it is sufficient to manufacture a part of the fin in elastomer. In other applications with higher solicitations this will not be sufficient for optimal service.
    We propose fins that yield but do not break or deform plastically. That they are not dented, twisted or deformed in any way that forces the operation to stop. We seek to achieve an unbreakable elastic element in service. This is particularly useful in critical machines such as large containerized dock cranes, the stoppage of which slows down or stops the entire operation of the port, affecting the ship, yard cranes, trucks and other machinery.
    It is inevitable that the fins collide with the container. Sometimes it is positive, since the direct hit of the hook to the container could cause more serious damage in one
    or in other than the breakage of the fin. The fin does, consequently, some bumper function, although very depleted with the current concept.
    For example, fins manufactured in three parts screwed together are used, see figure 5, the part that is coupled with the hook and the plates that serve as the mouthpiece being more robust. This ensures that most of the damage affects only the central area (the leaf springs), avoiding damage to the most valuable ones or to the main elements (load and hook). This application is intended to take another step and ensure that the blows received do not disable crossbows or fins, maintaining and improving current performance. Not only does the fin itself improve, but it becomes a real damping element to prevent damage to more important and expensive elements.
    It is essential that the fin continues to fulfill its function of mouth and guide for the latches. Therefore, the element must be flexible and elastic against impacts and overloads but must be rigid against normal loads and shocks in service. It is very useful to do this to the fin of a collapsible geometry. A profile that when reaching a certain buckling load, either by bending, twisting or compression.
    In summary, it is proposed to create an elastic flap, unbreakable in service, that dampens blows, yields to impacts but maintains the rigidity for normal work. This is achieved by combining elastic materials, sheets, sections in profile and elastic parts with frames or metal cores. The advantages achieved are:
    Reduce the number of fins to be repaired, either by breakage or deformation.
    Reduce damage to machinery and hitch structure.
    Dampen the bumps on the container and the load.
    Decrease significantly the number of hours lost and the loss of earnings
    activity. It should be remembered that the fins are often installed in machines
    criticism, whose delay directly implies a decrease in production.
    Get a safer device for operators. As can be seen in figures 3 and 4, the allele is an element that stands out from the assembly, being easier to hit people in case of operator neglect or machinery malfunction.
    Likewise, it is also expected to reduce damage due to impacts on other elements.
    that are in the work area of the hitch: trucks, wheelbarrows, others
    Containers, boats and crane elements.
    Replace an element characterized by its failure in service, with the corresponding losses due to corrective maintenance, with another more characterized by its wear, more susceptible pOf for both preventive or predictive maintenance, performed at scheduled stops.

    EMBODIMENT OF THE INVENTION
    The basic embodiment of the invention consists in replacing the intermediate plates in the flap (see figure 6) with two or more sheets of elastomeric material, synthetic rubber type, for example FPM (fluorocarbon rubber). In this case the bolt arrangement is respected and the total thickness is increased, from 50 to 100 mm depending on the type of service. The embodiment would in this case be limited to a pair of parallel assemblies, as shown in Figure 7.
    A more elaborate variant consists of using at least three layers of material in each crossbow of the pair (See figure 8). The two outer layers of low thickness made of composite material plus one or several internal soft rubber. The outer layers can be, by way of example, 5 mm thick, based on synthetic rubber with textile fabric and ribbed longitudinally with steel wire. Its function is to resist traction and protect the core from sunlight, dust, dirt, etc. The internal layers, with a total thickness over 40 6 60 mm, are responsible for providing the system with rigidity for normal service and facilitating elastic recovery after a large deformation due to impact or overload. For outer layers, preferably smooth sheets, ribbed sheets can be used.
    A third variant is to use as a core an elastic piece in the shape of a crosshead, profile 1, profile H or other geometries with an appreciable geometric stiffness but that buckles before overload or impact. The variant is represented in figure 9.
    Finally, the possibilities with better perspectives are those that combine the previous variants. Fins (integral or removable) whose central part is made of elastic material with a deformabk eml.x annatura: bida inside, or an encrdIllado of textile fibers, metal, plastic or any other type. Thus we obtain a more resistant, durable and rigid set in normal service; maintaining the characteristic of collapse collapsible geometry, and always maintaining the damping capacity of the whole.
    All the mentioned variants can be modified in the sense of making the whole flap of elastic material, or making the central area and the mouth of the flap integral, or any other imaginable variant that follows the concept of elastic flap developed in this writing.
