Description

~ 063532 ~ a present invention relates to container palcttes and the ~ navircs FOR ~ l ~ a hold for fish storage and ~ loose lace, especially fishing boats.
We know that modern trawlers generally include 5 a work room arranged above the fish hold and in which the fish is prepared. This wedge has a central corridor and lateral frames provided with ; ~ slides adapted to receive a stack of call plates generally short, intended to form vertical partitions shims and horizontal dividing the volume of the shim by comparing appropriate dimensions. ~ e ceiling of the hold is provided with openings communicating with the work room, by which the fish can be poured into ~ chutes or ramps adjusted to these apertures ~ and adapted to guide the fish in any compartment of the hold through the faces freed from their panels of the intermediate compartments res. ~ when we start to fill the hold, the brézes are removed from their slides to give access to the most moved back from the hold, then put in place as and when filling to form separate compartments full of poissonO To unload the fish, we operate in the i ~ ver-by gradually transferring the fish from the compartments in boxes that are transported out of the boat.
One of the drawbacks of such an arrangement is that the different rents ~ fish compartments are ~ uxtaposed and that there is no air circulation between these compartments, which next to the conservation of fish. U ~ another major drawback tie ~ t to the fact that the handling of the fish during its trans-fert in crates for unloading out of the boat requires a large workforce and adversely affects the quality of this fish.
We also know another type of fishing boat in which the hold has a central corridor and eta ~ eres side-Rales adapted to receive integral fish trays each of a palette. This wedge also has at its upper part re a xoulant bridge that can move transversely and long tudinally in the central couloix. ~ The crane is equipped a vertical arm on which can slide a cart fitted a fork whose parallel branches are arranged hori ~ -~ ontalement and can be oriented dpns their pla ~ common for - i,.

, come and get involved in the alvcolcs des p ~ lettes. Finally, the hold is equipped at one of its e ~ trcmites with a lifting platform this suitable for conveying the bins from the hold ~ us ~ eu in a txa ~ garlic room located above, and vice versa.
For loading, the trays ~ both stored in the room each bin is placed on the lifting platform teur, char ~ é in fish and ice, descended in the hold where he is seized ~ thanks to his pallet by the fork of the carriage then transpoxté by the pout-xoulant sux its éta ~ era.
For unloading, we perform the same operations in reverse order then t when the full bin was brought in by the lifting platform in the work room, we hoist it hoxs of the working boat hatch, using a crane which drop it off at the quay.
~ While the fish are not directly manipulated during the unloading operation, such an installation is unsatisfactory because it implements mec ~ ni-extremely expensive, hydraulic and electrical, including reliability is uncertain. However, as it seems very difficult to provide for the storage of fish caught in the event of failure of this-installation, there is a significant risk of seeing the boat unable to continue fishing in progress if such a failure occurs at sea. In addition, handling crates using the overhead crane can be quite tricky when that the boat is subject to a significant roll and / or pitch. ~ nfin, this installation makes it imperative that it exists ~ that of a cou-read this ~ unoccupied tral allowing access to the overhead crane ~ shelves receiving the bins, which results in a significant loss of storage volume, and exi ~ e many manipulations of tanks when loading fish.
The object of the present invention is to remedy these inconYe-~ ients using a container pallet for the storage of bulk fish and a vessel including a wedge suitable for receive these container pallets, which avoid any movement of container pallets in the hold during loading-- fish and any direct handling of the fish during dechaxification.
To this end, the invention relates to a container pallet.
of the type comprising a base provided with two parallel housings suitable for receiving the forks of a handling trolley, ~. .

~ 063s ~ 2 - and four p ~ lateral LlCallX ~ opposite ~ x two, characterizes in that two at least ~ pannes in xe ~ ard ~ have formed by removable panels.
According to another characteristic, the base of the pallet contencur according to the invention comprises a central opening and a removable bowl pierced with at least one hole suitable for closing sea said opening.
The invention also relates to a ship of the type taking a hold for storing bulk fish, means to subdivide said wedge into a series of delimited compartments ted by removable panels, at least one opening in the ceiling of the hold for the discharge of a melan ~ e icefish, e ~ royens adapted to guide the melan ~ e from said opening ture to any compartment ~ of the hold through the faces freed from their panels of intermediate compartments ~
- characterized in that said compartments are constituted by container pallets of the above type adapted to be individually transported out of the hold by said carriage and a lifting machine.
Other characteristics and advantages of the invention res-~ will derive from the description which will follow from several modes of realization of a pallet-conkeneur and a fishing boat pe of this ~ container pallets, made with reference to the drawings annexed on which:

- ~ A Fig.7 is a detailed perspective view of a stop - represcntée to ~ ig.6;
- ~ a ~ ig ~ is a schematic sectional view along the line 8-8 of ~ ig.5 ~
`If o ~ refers to ~ ig ~ 1 to 3, we see that the palettes-containers according to the invention, hereinafter called containers, are parallelepiped shape and each have a rectangular base ~ ulaire 1, four uprights 2 fi ~ ies respectively to the four corners of the base 1, and ~ n upper frame 3 together ~ ant the uprights `2 between them at their top.
As shown in more detail in ~ ig.4, the base 1 forms a pallet consisting of a rectangular frame lower 4 including two of the sides p ~ parallel have lodge-elongated elements 5 of rectangular section adapted to receive the two forks of a forklift. ~ e frame 4 delimits internally a rectangular opening 6 adapted to receive ~ oir and be closed by a bowl 7 whose edges are supported ~ ur the sides of the frame 4 when it is in position in the ou-~; verture 6 ~ ~ u center of the bowl 7 is formed a hole 8 which the utility will appear thereafter. As the different parts constitutive of the container are mé ~ al, preferably in unalliage lé ~ er based on aluminum, the underside of the frame 4 is covered with a plate 9 matching the outline of the frame 4 and made of non-slip material, preferably counter plated, to prevent the container from slipping when it rests on a metal surface subjected to oscillations. Of ~ even the ~ ace superior of each lo ~ ement 5 is also ~ alement recou-~ erte of a plate 10 of the same material to improve the stabili-of the container when it is supported by the forks of a truck.
Each ~ ontant 2 is constituted by an angle whose - wings 11 perpendicular to each other are welded at their ends ~ lower half of a corner of frame 4, in the extension of - side faces ad ~ acentes thereof. ~ 'upper end angles 2 is capped by the frame 3 whose four sides consist of angle-shaped elements having each cun one wing pressed and welded against the wings 1 ~ of two mon-2 adjacent tants and a wing extending inward perpen - specifically to the first. ~ e container is thus largely open at its upper part where it is provided with four parts ~ 0 12 elongated, each arranged at a corner of the frame 3 and welded -. . ................................................

each on the sides of the frame 3 adjacent6 to this corner. Every corner of frame 3, each piece 12 thus fits, with the two c8tés correspondants de ce cadre, une trian ~ ulaire 13 intended, as will be seen later, to receive the hook a lifting device.
Each corner of the cad ~ c 3 is also provided with a part protruding 14 while the base 1 has at ~ es corners, on - Its underside, corresponding cutouts 15, such way q ~ JI ~ we can ~ stack containers by interlocking the protruding parts 14 of a container in the cutouts 15 of the neur who overcomes it.
~ ur faces facing the interior of the container wings 1 'are welded angles 16 delimiting with these faces slides 17 adapted to receive panels forming the sides of the container.
Support pieces 18 having the shape of a "U" including one branch would be shorter than the other are welded each to half height of the container on one of the wings 11 of each mount ~ nt 2 by their longest wing, and on the angle 16 integral with this wing 11 by their shortest wing, in a position suitable for mena ~ er an interval between the part 18 and the cor-nière 16 integral with the other wing of this amount 2. ~ es pieces ~ 8 are arranged so that the aforementioned intervals are arranged two by two in two planes parallel to two faces opposite sides of the container. These parts 18 are intended to support the ends of two crosspieces 19 each having an edge longitudinal 20 mistletoe, when the crosspieces are in place, is housed at each of its ends in one of the inter ~ aisles separating a piece 18 of a neighboring angle 16. In this position, the - 30 sleepers 19 are parallel to two opposite sides of the container and can receive a shelf 21. This a ~ encement allows easily lift, by simple lifting, the shelf 21 and the traYexses 19 and, as we will see now, to ensure - in some cases the complete opening of the corresponding faces ~ 5 from the container.
Referring more specifically to ~ igo3 and 4, we sees a container, hereinafter called type C, the two pan-- ~ neaux 22 adjacent to the crosspieces 19 and parallel to the housings 5 each consist of a flat sheet of ~ rectangular elm-re provided with reinforcing folds. ~ panels 22 are ~.
, ''.

ma: Lntenus lateralemeIlt in the slides ~ 7 and s ~ extend over the entire height of the container C cntre the frame in ~ érieur 4 and le cadre supéxieur'3 ~ As a result, these two sides of container C
are completely closed and the panels 22 are irremovable.
PRr against, the other two panels 23 of container C
are constituted by elements of panels or breezes 24 which have been stacked on top of each other in the slides 17. Each element 24 is constituted by a profile comprising an elongated flat part, the two longitudinal edges of which are parallel and folded back on the same side of the flat part so to fo ~ mer each a rim 25a having the shape of a ~ L "including one branohe is parallel to the flat part. These edges 25a allow try to easily grab items 24 to get them out of 'glissièxes 17 or introduce them therein. Moreover, the two end edges 25b of each element 24 each have a rounded ~ me defined by an arc of a circle having for cent be the center of the element 24 so ~ ue, ~ uelque is the-clinching of an element 24 relative to the slides 17, this element cannot get caught in these slides. this allows to easily set up one after the other the pre ~
miers elements 24 by presenting them obliquely in the plane of slides 17 then by tilting them therein. ~ ors-there is not enough space between the last element 24 inserted and the inner rim of the upper frame 3 to proceed thus, the following elements 24 ~ are introduced through the upper part r ~ 'eu ~ e de's slides 17.' ~ this effect, '' the angles 16 are stopped at a distance from the internal edge of the frame 3 slightly ~ higher than the height of an element 24 so that, when ~ u'un'élément 24 is brought into abutment by one of its edges 25a against this ledge, it is completely disengaged from its slides 'res 17 and can be entered in the latter by simple trans-latio ~ down. We put in place in this way the last elements 24 until a complete panel 2 ~ is formed. For dismantle such a panel, just perform the same operations-in reverse order.
As o ~ can see on ~ ig.3, the height of the elements 24 is suitable for ~ if there remains a space between the element 24 above and frame 3 when all the elements 24 are in - place, fa ~ on to provide an open ~ re 26 allowing a circu- ~
lation of air when several containers are stacked and .

On the ~ i ~ .2 is represented a type B container which is analogous to container C of ~. Container B presents two panels 23 identical to that of container C and two panels 27, parallel to the logeme ~ ts 5, which are constituted each by two half-panels, namely a lower half-panel fixed eur made up of a sheet similar to that of the panncau 22 of container C but spanning half the height of the container, and an upper half-panel consisting of a stack of elements 24 identical to those of panels 23.
According to the invention, a third type A2 of container not shown on ~ ig. consists of a similar container to that of Fig.2, but in the ~ uel lo ~ ements 5 are parallel to removable panels 23.
~ nfin, Fig.1 shows a fourth t ~ pe A1 of story-neur comprising four fully removable panels 23 consisting of titled elements 24.
~ a Fig.5 is a sectional ~ ue taken at ni ~ water from the hold of a fishing boat according to the invention. This boat includes a wedge 30 delimited by its hull 31, two walls or partitions of ex-- ~ end 32 and 33, a floor 34 and a ceiling 35. Between the hold 30 and the deck of the boat is arranged a work room 36 in which the fish p ~ ch ~ is prepared before being stored in the hold. ~ Finally, the hold 30 and the work room 36 are provided with two hatches 37 and 38 respectively for access to outside.
The interior of the hold 30 has a central corridor 39 the same width as the hatchway ~ 7, delimited on each side by a frame or pallet rack 40 extending over the entire length of the hold. As seen in ~ ig.6, each frame 40 includes a first row of vertical posts 41 bordering the corridor 39 parallel to the axis ~ -X of the boat and a second-me row of vertical posts 42 parallel to the first and disposed between the first ran ~ ée and the shell 31. ~ es posts of the two rows, which extend from the floor 34 to the ceiling ~ 35, are re ~ ully spaced from each other by the same interval of a row to another and are aligned two by two perpendicularly to axis XX of the boat. Two horizontal beams 43 and 44 extend tend respectively at floor level 34 and halfway up posts, between the shell 31 e ~ each po ~ water 41, . . .

, ~ 106353Z
perpendicular to the XX axis of the boatO At each end of the calej of the upper beams ~ 44 are fixed directly against partitions 32 and ~ 3. ~ beams 43 and 44 consist ~ ent wings l ~ térale 45 and form two by two of the upper spans riors and inferior intended to receive containers.
- Co ~ me show it ~ i ~ .5 and 6, the central corridor 39 is also suitable for receiving containers on two levels calves. For this purpose, the floor 34 is provided with holes 46 in which can be introduced stops 47. Referring in ~ ig.7, we see that each stop 47 includes a tube provided a flange on which are offset offset angles relative to each other and in which can ve ~ ir to embed the lower corners of four level containers inferior. Similarly, the ceiling ~ d 35 is equipped with means (not shown) allowing ~ ixer stops 47 in a position cleared or in a locked position in which they are inserted into the upper corners of containers of the higher level.
8 on the posts 41 are also provided with ~ organs (not shown) adapted to come to form a stop against neighboring corners of the containers adjacent to these posts, as well as ^ ~ means (not shown) for locking on their slides-res the containers received in each frame 40.
We will now describe the arrangement of the tales neurs according to llinvention in the fishing boat described above.
So ~ ue the boat apart for fishing, volume of the hold 30 is completely occupied by empty containers A1- ~ 2 ~ B and C.
As can be seen in ~ ig.5 and 8, the containers A1 are arranged in the center of corridor 39 in two long lines stacked dinals, A1 containers in the upper row - being nested on containers A1 of the lower row as previously described. On each side of the A1 containers are arranged two superimposed rows of containers A2. ~ es cont-nors A1 and A2 are immobilized at the top and bottom by the stops 47 and they are joined together at their upper part by spacers (not shown) at hatch 37.
~ The frames 40 are lined with containers of types B and C:
over most of the length of the hold 30, each upper bay has a container C in the vicinity of the hull and two containers ~, and each lower bay has a container C in the vicinity of the hull and a container B.
side of the bow of the ship the width of the cule and that of each frame 40 gradually decreases and, as can be ~ see at ~ igo8 whose part to the left of the gX axis corresponds to lays the upper spans and whose ~ right part of the axis X ~ X corresponds to the spans in ~ é ~ ieure, the number of containers per span also decreases. In addition, the length of the containers : C can be different from that of containers B to allow optimal occupancy of the hold volume by combining these , 10 deuY. types of containers on each frame 40.
The arrangement of the different co ~ contents will be better understood.
with particular reference to the two rows trans-versales ~ uperposées 4 ~ of ~ ig.8 for which ~ orienta-tion of the housing 5 of the containers has been shown schematically in lines - 15 discontinuous. Given this orientation and layout containers A2, B and a, we see that the removable panels 23 of these containers are all arranged parallel to the axis ~ XX of the boat. In addition, since the containers A ~ comprise be removable panels 23, it is understood that it is possible for a person to reach into the hold any container - ~ from the upper level or higher by moving next ; in front of the axis of the boat in the containers ~ 1 then, arriving at right of the sought container, perpendicular to this direction tion, this displacement being permitted by the possibility that this ~ 5 person to disassemble ~ es a ~ after J.es other panels 23 And the shelves ~ 1 which obstruct its pro ~ ression.
For the storage of fish in the hold, it is planned, as known per se, openings 49 in the ceiling 35 of the hold and telescopic troughs or ramps G
able to adapt to these openings. ~ when fish have been caught and prepared in work room 36, we have a chute between one of the containers C of the upper level adjja-cent at the bulkhead 32 and the nearest opening 49, making sant pass this chute through the sides freed from their elements 24 of intermediate containers B and A2O Shelf 21 . and the bowl 7 of this upper container C as well as the shelf ~ 21 of container C immediately below having been removed, a mixture of fish and ice is poured through the opening 49 in the chute ~ ui guides this mixture in the upper container ~ aforementioned, from where it falls through the opening 6 in the container C inf ~ ricur. ~ when the latter is pre ~ uc to half filled, we put back its shelf 21 and the elements 24 which have allowed access to this shelf, and we fill the upper half eure of this container D ~ when this container is full, we close the opening 6 of the upper container C with the bowl 7 and we raises the access panel 23 to the height so that fill the lower half of the upper container C. This being carried out, place the shelf 21 as above and the elements 24, and we finish filling this container. We then pass in the group of two immediately adjacent containers B along from the partition ~ 2, then to the next group, and we thus fill all of the sixteen containers adjacent to this partition.
~ when one span is fully occupied, we move on to the next and, step by step, using the appropriate opening 49, all or part of the containers are filled as required.
The fish thus stored can be kept in good conditions ~ thanks to the air circulation which is made between containers through their side openings 26 and above and to the possibility for the water from the melting of the ice to flow through the holes 8. For this purpose, it can also Holes in the shelves 21 should also be provided.
trim the containers in two parts by the shelves 21 ~ `é ~ ite that the fish below is not crushed by the ~ enough of that ~ ui overcomes it, while allowing the realization-tio ~ of units large enough to decrease the mani-pulations during loading and unloading.
This unloading is carried out as follows: when the boat is docked, the hatches ~ lles 37 and 38 are open and we go out, using a crane with four hooks which are rec ~ us in the openings 13, the nine containers of the level - ~ upper (shown in dashed lines on ~ ig.8) arranged - immediately below the hatch ~ 7. We then take out the nine corresponding lower level containers, pUi5 on-crane in the space freed up using a crane forklift intended to successively bring lss other containers under the hatch, from where they are hoisted out from the boat by the crane.
To load the containers in the hold, the same operations are carried out as for unloading, but - 40 in reverse order.

11 ' Although hatch 37 has been described as permitting to deliver the passage to nine containers, this value is not ~ t, s critical: the dimension of the tool 37 must only ~ ent self-riser unloading a sufficient number of containers to allow descent and rotation in the space freed by these containers of the mc ~ nutention cart with son.premier story- -neur. Likewise, the width of the central corridor must be sufficient ~., health to allow passage and xotation, of the trolley with - ~ a ch2rge.
