    Title: Elevator
    Lifting apparatus comprising: a holding compartment, the holding compartment comprising: a base member having a proximal end adapted to be placed on a surface area, and a distal end adapted to accommodate at least one stackable container, an upper a portion comprising a hoist coupling which provides a connection between the hoist and a hoist which permits the hoist to be lifted and lowered via the hoist, at least one supporting structure extending between the base member and the upper member, spacing it apart; the base portion and the upper portion forming an internal volume of the holding compartment, an opening in a boundary region of the holding compartment adapted to provide access to the holding volume of the holding compartment.
    In the transport, shipping and / or fishing industries, there are a number of situations that require the unloading of goods or items lifted from the transport vehicle or vessel using a lift or crane.
    There are a number of different situations that require items to be stacked on top of each other to reduce hoisting time when there are multiple items to be unloaded from a vehicle or vessel. Such stacking is commonly used when the items to be hoisted are identical and the top of one item is arranged to fit into the bottom of another item. Such a device can be seen e.g. for stacking boxes which are designed to carry the goods temporarily and are reusable, such as a stackable plastic bottle box.
    In the fishing industry, fish are often unloaded from a fishing vessel by packing the fish in ice and into containers, such as plastic buckets, where the bucket is used to transport the fish from the fishing vessel to a fish processing plant. The buckets have different sizes from approx. 200 liters to 1400 liters, where the general size of a bucket can be close to 700 liters. The buckets are often provided with loading slots which allow a forklift to slide between the bottom of the holding tank and the foot of the bucket to safely lift the buckets when transporting.
    In addition, the buckets are often arranged in such a way that their bottom or foot have a dimension such that the outer dimension of the foot is equal to or smaller than the inner dimension of the top of the bucket, so that the buckets can be stacked during transport with to allow a number of buckets to be loaded by a vessel at any time. The stacking is carried out by placing one or more buckets on top of a first bucket, the unloading being done by lifting the first bucket with a lifting fork, and lifting a stack of buckets from the vessel upwards to the jetty or onto a transport vessel.
    However, there have been many instances where the hoisting of a stack of fishing boats has gone wrong and the bucket stack has fallen apart during the hoisting process, with the result that one or more buckets have fallen from the stack back to the vessel or jetty and this is a great danger to the staff who assist with the hoisting process. Cases have been reported in which the pile has been lifted from a holding boat in a fishing vessel and the bucket has hit the loading crew, who are in the holding bay under the fork.
    Thus, it is necessary to provide a hoist which allows stacking of a plurality of holding containers while reducing the risk of the containers from falling if stacking occurs during the hoisting.
    According to the invention there is provided a hoisting apparatus comprising: a holding space, the holding space comprising: a base member having a proximal end arranged to be placed on a surface area, and a distal end adapted to accommodate at least one a stackable container, an upper portion comprising a hoist coupling which provides a connection between the hoisting apparatus and a hoisting device which allows the hoisting apparatus to be lifted and lowered via the hoisting apparatus, at least one supporting structure extending between the base member and the upper member; it forms a distance between the base part and the upper part and forms an internal volume of the holding compartment, an opening in a boundary area of the holding compartment adapted to provide access to the holding volume of the holding compartment, the hoist further comprising a closing mechanism having a closed position, arranged to block at least part of the opening when the hoist is lifted f the surface area, and an open position adapted to remove the blockage of the opening when the hoist is located on the surface area, whereby the closure mechanism is coupled to the connection between the hoist and the hoist, where an internal traction force in the connection moves the closure mechanism to its closed position, and / or where an initial absence of traction moves the closure mechanism to its open position, or the closure mechanism is connected to a lever that contacts the surface area where the hoist is located, where the lever transmits mechanical energy to the closure mechanism to move it to its open and / or closed position.
    Whereby the upper portion and the base portion form the upper and lower boundary regions of the holding compartment, the base portion being adapted to carry the load of one or more stackable containers, and the upper portion limiting how many containers can be stacked within the holding compartment. The peripheral region of the upper portion and base portion may also be considered to form the radial boundary region of the holding compartment, wherein the radial boundary region may be considered as the boundary region extending in a radial direction from the radial axis of the apparatus, the radial axis extending in a direction between the base portion and the upper portion and may be perpendicular to the lower boundary region of the base portion. The opening may be located in a radially bounded area of the holding compartment where the opening provides access to the inner volume of the holding compartment and permits stackable containers to be inserted or removed from the holding compartment as desired. The support structure is attached to the upper part and the base part and is adapted to transfer loads from the upper part to the base part, so that the base part and the upper part are inseparable during use of the hoisting apparatus. This means that when the lifting device exposes the upper part to traction, the load of the traction force is transferred to the base part, ensuring that the traction applied to the upper part results in the entire lifting device being lifted from the surface. The carrier structure may be one or more carrier bars extending between the peripheral region of the upper portion and the base portion so that the carrier bars may delineate portions of the radial boundary of the holder space. The support bars may be vertical support bars extending between the upper portion and the base portion parallel to the radial axis of the hoisting apparatus. Further, the support bars may be diagonal support bars extending diagonally from the upper portion to the base portion to provide both structural integrity in a vertical direction and also in a horizontal direction. The support structure may further take the form of one or more diagonal support rods which intersect in a region between the upper part and the base part to provide additional structural strength to the hoisting apparatus to ensure that the upper part and the base part are rotationally fixed (i. plane perpendicular to the radial axis of the hoist) relative to each other when the hoist is fully loaded.
    The opening of the holding compartment may be located in an area between the upper part and the base part, where the articles can be placed within the holding compartment. The aperture may be located in a radially boundary region of the hoist so that when the blanks are filled into the interior volume of the space, they pass a radial region of the aperture and vice versa when the blanks are removed again. When the blanks, such as a plastic bucket, are positioned within the holding compartment, it may be advantageous that the blank does not cross the opening area, ensuring that the closing mechanism can block the opening.
    The closure mechanism is adapted to allow access to the internal volume of the holding compartment through the opening when the hoisting device is securely placed on a surface and one or more items are allowed to be safely stacked within the holding compartment while the lifting device is in a safe position. In addition, the closure mechanism is arranged to ensure that when the hoist is to be lifted from a vessel, a ground surface area and / or other areas where the hoist can be used, the opening of the hold compartment is blocked so that the items placed inside the hold compartment cannot fall out. of the internal volume while the hoist is lifted. If a stacked item rolls out of the stack, the closing mechanism ensures that it is prevented from leaving the holding compartment via the opening.
    Thus, a number of stackable containers can be hoisted from a vessel and lifted into the air, without any risk of any imbalance or impact affecting the containers, resulting in them toppling over and risk damaging any personnel under the hoist during unloading of the vessels from the vessel. In one embodiment, the upper portion and the base portion may have substantially the same dimensions in the regions perpendicular to the radial axis of the hoisting apparatus, such that the radial boundary region of the holding space, which may be determined by the upper portion and the base portion periphery, may be in substantially parallel to the radial axis of the hoist. In one embodiment, the holding compartment may further comprise a second opening which provides a second access to the holding compartment. This second opening may allow access to the holding compartment from more than one area. This means that when the items are brought into the holding compartment, the insertion can be made from two separate sides of the hoist, which can be advantageous when there is little space available, such as in a storage area of a fishing vessel. In addition, the second access can reduce the risk of personnel injury, as the second access can reduce the amount of rotation needed to properly position the hoist for reading and unloading while the hoist is in the air. In one embodiment, the aperture may have a substantially rectangular dimension where the horizontal dimension X is greater than the vertical dimension Y, with X being at least 2 times larger than Y or especially 3 times larger than Y. The horizontal dimension of the aperture which controls the maximum width of the workpiece that can be inserted into the holding compartment, while the vertical dimension controls the maximum height of the workpieces introduced into the space. By the horizontal dimension being larger than the vertical dimension, objects having a given width can be stacked on top of one another until the maximum height is reached. For example, the opening has a horizontal dimension of just over 1.5 meters and a vertical dimension just over 3 meters, a single stackable workpiece having a width of 1.5 meters and a height of approx. 1 meter, stacked together with two other items to form a approx. 3 meters high stack and inserted into the holding compartment opening. In this example, the maximum number of items that can be stacked is thus three, while the space can easily contain both a single item or a stack of two items. Alternatively, in another example, the height of the stackable items may be higher or lower, which means that fewer or more items can be stacked within the space, where the amount of stackable items depends on the height of the stackable item and the height (vertical dimension) of team room. In one embodiment, the holding compartment may comprise one or more side walls extending between the base portion and the upper portion forming an outer boundary region of the holding compartment. This sidewall can be seen as a radial boundary region of the holding compartment and which does not provide a workpiece access to the interior volume of the compartment and is arranged to ensure that the workpiece cannot leave the holding compartment via the sidewall. That is, the sidewall can be considered as the portion of the radial boundary region of the holding compartment which has no opening to provide access to the holding compartment. The sidewall may be of any shape as may be suggested by one skilled in the art. These are diagonal support rods, solid metal pieces, a plurality of vertical and / or horizontal rods or any suitable construction which ensures that the stackable workpieces placed within the holding compartment are prevented from falling out of the holding compartment via the side wall. In one embodiment, the closure mechanism may comprise a movable boom adapted to be moved into the area of the opening to block at least a portion thereof. The boom may be arranged to traverse the area of the opening so that when the closure mechanism is in its closed position, the movable boom is in a locked position that crosses the opening, ensuring that a workpiece located within the holding compartment cannot leave this by blocking the items while the closing mechanism is in its closed position. The movable boom may be placed diagonally, vertically or horizontally across the opening to prevent the items from leaving the holding compartment. The movable boom may be arranged to ensure that no area of the aperture is greater than the height or width of a single workpiece placed or placed in a stack within the holding compartment.
    In addition, the closure mechanism may be provided with two or more movable booms across a single opening to reduce the risk that a workpiece will leave the holding compartment when the closure mechanism is in its closed position, and to arrange the hoist to carry items which may have a dimension which is substantially smaller than the width and / or height of the opening. The two or more booms can be used to ensure that no area of the opening is large enough to allow a workpiece to leave the holding compartment while the closure mechanism is in its closed position. In one embodiment, the closure mechanism may comprise a movable boom wherein a first end of the movable boom may be pivotally fixed to the base member and a second end is movably secured to the upper portion and adapted to pivot over the opening area by sliding along part of the upper part. Thus, when the closure mechanism is in its open position, the movable boom may be rotated to a vertical position parallel to the radial axis of the hoisting apparatus, thereby abutting the vertical boundary region of the opening and ensuring that the movable boom does not reduce the opening area. However, if the closure mechanism is in its closed position, the movable boom is pivoted over the opening area, the first end being secured to the base portion at the opening periphery, while the second end sliding along the upper portion allowing the boom to extend over the opening of the holding compartment and blocking access to the outside of the articles within the holding compartment via the opening. Such a movable boom provides a reliable repeatable closure of the aperture, since only one end of the boom is adapted to move while the other end is fixed in place. In one embodiment, the closing mechanism may be coupled to the connection between the hoist and the lifting apparatus, where an initial pulling force in the connection moves the closing mechanism into its closed position, and / or where an initial absence of a pulling force moves the closing mechanism into its open position. This means that when the traction is applied to the hoist, the shutter canism begins the closing and vice versa. This provides a reliable closing mechanism which reduces the need for personnel to handle the closing mechanism and further ensures that while the hoist is in the air, the closing mechanism cannot be opened by mistake, thereby ensuring that the opening is blocked while the hoist is in.
    The closure mechanism may be mechanically coupled to the connection between the lifting apparatus and the hoisting apparatus so that the traction provided by the lifting apparatus is transferred to the closing mechanism. For example, the lifting force of the lifting device can provide a mechanical force on a lever, where the lever can transfer the mechanical force to a movable boom such that the transferred mechanical force moves a movable boom from an open position to a closed position. In one embodiment, the closure mechanism may be coupled to the lifting apparatus and ensure that the closing mechanism remains in its closed position at any time when there is a traction between the hoisting and lifting apparatus. The closing mechanism may be provided with a locking mechanism which ensures that when there is a traction between the lifting device and the hoisting device, the closing mechanism is prevented from moving into its open position. This is to ensure that the force of a workpiece overturning, tipping or tilting within the holding compartment cannot force the closing mechanism from its closed position to its open position. The locking mechanism can be activated and deactivated by the traction between the hoist and the hoist. In one embodiment, the closure mechanism may comprise a spring mechanism which ensures that the closure mechanism moves into its open position when the hoist is placed on a surface area. This means that when the mechanical forces that move the closing mechanism into its closed position are not present, the spring will counteract the forces and move the closing mechanism into its open position. One skilled in the art can adjust the spring forces to be smaller than the mechanical forces arranged to bring the closing mechanism into its closed position.
    This ensures that the spring forces are not large enough to prevent the closing mechanism from moving into its closed position when the hoist is tilted, but large enough to move the mechanism into its open position when the apparatus is ready to be unloaded. In one embodiment, the dimensions of the region at the distal end of the base member may be arranged to receive a EUR pallet. This means that the stackable workpieces can be placed on a standard pallet which allows the hoist to be loaded and unloaded using a forklift. In other embodiments, the dimensions of the area may be arranged to receive various sizes of stackable containers.
    The invention is described in more detail below with reference to the drawing, in which: Figure 1 is a perspective view of the hoist apparatus according to the invention; Figure 2 is a perspective view of the same in open position loaded with containers; Figure 3 is a perspective view of the same in closed position loaded with containers; Figure 4 is a perspective view of the same in open position ready to be unloaded; Figures 5A and 5B are perspective views of portions of the hoist showing the movement of the closure mechanism; and Figure 6 is a perspective view of an embodiment of the hoist according to the invention, an opening.
    Figure 1 shows a perspective view of a hoisting apparatus 1, wherein the hoisting apparatus comprises an upper part 2 and a base part 3. The upper part 2 is connected to the base part 3 via support structures 4, 5, 6, which comprises a first sidewall 4, a second sidewall 5 and a vertical support bar 6. The support structure ensures that the base portion 3 is attached to the upper portion 2 and further provides a radial boundary region for the inner volume of a support compartment 7.
    Alternatively, the apparatus may be provided with vertical support rods 6 at each of the corners of the base portion, enabling the upper portion 2 to be attached to the base portion, and providing a radial boundary region for the internal volume. In addition, the hoisting apparatus 1 may be provided with fixed structures between the horizontal posts to prevent access of stackable items into and out of the holding compartment in any area other than those specially designed for access, such as openings 12 and 13. The stackable items are thus unable to overturn and exit the apparatus 1 via the sides of the apparatus which are provided with fixed structures. The fixed structures can be rods, nets, fixed walls and any other type of fixed structures that can close off for access to the holding compartment via the non-intended sides.
    The base member 3 has a first end 8 or a first surface which is arranged to be placed on a surface area (not shown) to provide a stable foundation for the hoisting device when placed on the ground. The base member 3 has a second end 9 or other surface which is adapted to receive a stackable workpiece and provides a stacking foundation for the workpiece to be placed thereon. The other end 9 may also be arranged to contain a EUR pallet on which the articles can be stacked.
    The upper portion 2 and the base portion 3 are of rectangular shape, having substantially rectangular corners 10 and straight members 11 extending between the four corners 10. The outer surface of the straight members and the corners form a radial boundary region of the holder space, wherein the holder space is delimited by the upper portion 2, the base portion 3, and the side walls 4, 5, and the vertical bar 6 such that the inner volume of the holding compartment 7 is substantially cubic, its boundary region being defined by oppositely placed parallel planes.
    The apparatus 1 holding space 7 is provided with a first opening 12 and a second opening 13 which is defined by the radial boundary region between the side walls 4, 5 and the vertical rod 6. The openings 12, 13 are located on two sides of the boundary region and enable access to the holding compartment 7 from two different positions.
    The side walls 4, 5 ensure that the workpieces located within the holding compartment 7 cannot leave this in a direction from the radial axis A of the apparatus 1 towards the side walls, being accessible only through the openings 12, 13.
    The upper part 2 is provided with connecting means 14 in the form of eyes which allow a lifting device (not shown) to be connected to the hoisting device 1, thereby opening the possibility for the hoisting device 1 to be lifted from the ground. The openings are provided with a closure bar 18 which, in its open position, is arranged vertically in an area near the side walls 4, 5 adjacent to the opening, so that the bars do not reduce the area of the openings 12, 13.
    Figure 2 shows the hoisting apparatus shown in Figure 1, in which three stackable plastic buckets 15, 16, 17 have been inserted into the holding space 7 of the apparatus 1 via the openings 12, 13. The openings 12,13 have such a dimension that the plastic buckets 15,16,17 can be inserted into the compartment 7 in a stacked position, ensuring that the buckets 15, 16, 17 are within the radial boundary region of the holding compartment 7. This implies that the widths of the openings 12, 13 are greater than the width of the buckets 15, 16, 17. The lower bucket 17 is securely located on the other end 19 of the base member, and the first end of the base member is located on a surface area while the buckets are inserted into the apparatus 1. The number of plastic buckets may be different depending on the height of the individual bucket, ie. that when higher buckets are stacked, only one or two buckets can be carried, while the capacity of the hoist is such that more buckets can be stacked, e.g. 4, 5 or more if the buckets to be stacked are lower.
    Figure 3 shows the hoisting apparatus shown in Figures 1 and 2 when the lifting device has applied traction to the connecting means 14 and the apparatus has been lifted in the direction shown by an arrow B. As the apparatus is lifted from the surface area, the rods 18 rotate in a direction shown by arrows C and D, the first end 19 being pivotally attached to the base member, while the second end 20 sliding along the horizontal beam 21 of the upper part. a direction away from the sidewall 4, and the sidewall 5.
    The rod 18 may be mechanically connected to the lifting eyes 14 in such a way that any traction applied between the lifting device and the eyes 14 is transmitted to the closing mechanism to actuate the rods for sliding along the horizontal beam, thereby blocking the opening 12, 13. Thus, the blocked openings 12,13 ensure that the buckets 15,16,17 cannot leave the holding compartment 7 while the hoisting device is removed from the ground. Should the top bucket 15 accidentally tilt away from the adjacent bucket 16, the bars 18 and the side walls 4, 5 ensure that the bucket cannot fall out of the holding compartment in the direction of the ground when the bar 18 blocks the bucket over to pass in. in the opening.
    Alternatively, the closure mechanism may be connected to a lever which contacts the surface area of the location of the apparatus 1, whereby the lever transmits mechanical energy to the closure mechanism and causes the rod to rotate, as shown in Figure 3.
    Figure 4 shows the apparatus 1 when placed on the ground in a direction shown by an arrow B ', whereby the rods 18 have been made to rotate in the opposite direction with respect to Figure 3 or in the directions C 'and D'. The rotation in the opposite direction ensures that the openings 12, 13 are free and unblocked and allow staff to remove the buckets 15, 16, 17 from the holding compartment.
    Figure 5 shows a hoisting apparatus 1, in which the base part 3 is shown partly and the support structures 6 in the form of oppositely placed vertical bars, which are located on the opposite corners of the base part. The first end 19 of the rod is pivotally attached to the base, while the other end is arranged to slide along the horizontal beam, as shown in Figure 3. Figure 5A corresponds to the position of the rods shown in Figure 4, while Figure 5B corresponds to the position of the bars shown in Figure 3.
    The other end 20 of the bars has a fastener 22 which is attached to a mechanical connector 23, i.e. a wire in which the wire is attached at one end to a weight 24 and at the opposite end to a lifting connection (not shown) which allows the lifting device, i. a hook on a crane to be mechanically connected to the hoisting apparatus 1. The wires are passed through pulley-like structures 25, 26, 27, which allow the direction of the wires to be changed and the ends of the wires mechanically connected to the weight 24 and the lifting apparatus. When the hoist is placed on a surface in the situation shown in Fig. 5A, and no force is applied from the hoist to the hoist, the weights 24 pull the rods 18 into a vertical position which allows access to the hold space 7. This means that the wires 23 are in the a first position where the force applied to the weight end of the wire 23 is higher than the force applied at the opposite end. The force applied to the wires by the weight 24 is shown by arrows E. This force E ensures that the other end 20 of the rod 18 is pulled in the direction shown by arrows F so that the rods release the hoisting device. however, when the hoist 1 is lifted from the surface, as shown in Fig. 5B, the traction applied to the first end of the wire 23 by weight is less than the force applied by the hoist; and which pulls at the opposite end 28 of the thread. This direction of force is shown by arrows G. Mostly, the weight 24 is lifted and the thread 23 is displaced in the direction G of the force and causes the other end 20 of the rod 18 to move in the direction shown by an arrow F1 when the fastening means 22 on the other end 20 is attached to the thread. The rod is thereby turned from the connection at the first end 19 so that the rod 18 blocks the openings 12, 13 and ensures that the buckets (shown in Figures 3 and 4) cannot fall out of the holding compartment.
    The wires 23 may be in the form of ropes, cables, chains, belts or any mechanical connection which permits the transfer of forces from the lifting apparatus to the rods 18 or weights 24.
    Figure 6 shows an alternative embodiment of the present invention, in which the base part 3 is provided with an opening 28 which allows access to the holding space 7 along the surface area on which the apparatus 1 is located. The opening 28 is open to one side of the base member and allows access to a central region of the base member, whereby the stackable members are held by the base member at its peripheral edges 29, 30, 31. By providing such an opening 28, a lifting device, a handlift or a pallet lift is rolled over the surface area and into the holding compartment via the opening 28, where the pallet forks can and / or the lifting machine wheels can access the holding compartment via the opening 28, the forks can be raised so that the bottom of the stackable workpiece is located say high enough that it will not cross the peripheral regions 29, 30, 31 of the base member and can be lowered when the stackable blank is inside the holding compartment 7 so that the peripheral regions of the stackable blank rest on the top of the peripheral areas, ie second end 29, 30, 31. of the base member 3. The remaining portions of the hoisting apparatus of Figure 6 are similar to those shown in Figures 1 to 5. Figure 6 also shows how the wire 23, shown in more detail in FIG. Figures 5A and 5B extend through and up over the upper portion of the apparatus 1 and may be in a mechanical connection with the lifting apparatus, a hook or a hoisting transducer connecting the hoisting apparatus to the lifting apparatus.
