Description
A vehicle comprising a partition wall, and a method of manufacturing a partition wall
The present invention relates to a vehicle for cooled transport, said vehicle comprising
- a cargo section comprising a cargo space, said cargo section comprising an closable access opening, a floor, longitudinally extending walls and a ceiling,
- a partition wall for dividing the cargo space into two compartments with a first compartment relatively far from the access opening and a second compartment relatively close to the access opening, said partition wall capable of being
- in a first position transverse to the floor and transverse to the longitudinally extending walls, said first position closing off access between the two compartments, and
- in a second position allowing access from a second compartment area of the second first compartment to a first compartment area of the first compartment;
wherein the partition wall comprises a partition wall module, said partition wall module comprising in the first position of the partition wall
- a top edge section, said top edge section comprising a top edge,
- a bottom edge, and
- two side edges extending between the top edge and the bottom edge;
wherein the partition wall module comprises
- an insulating panel, and
- a first main side facing the first compartment and a second main side facing the second compartment, and at at least the second main side thereof a plate for protecting the insulating panel.
A vehicle according to the preamble is known in the art. It is for example used in the combined transport of cargo comprising goods that need to be maintained at different temperatures, for example combined transport of goods that need to be frozen and goods that merely need to be refrigerated. Typically, the goods that need to be refrigerated are in a second compartment that is close to the access door, which is typically at the rear of the vehicle, whereas the (first) compartment for frozen goods will be away from the rear of the vehicle. During transport the partition wall is in the first position, allowing the compartments to be at different temperatures. During loading or unloading of the frontmost (first) compartment, the partition wall will be in the second position. During loading or unloading of the rearward (second) compartment, the partition wall will be in the first position.
It is a problem that during loading of the rearward compartment a load may be run into the partition wall. This impact may cause damage to the partition wall. The known partition wall is fortified with plastic plates bonded to the hard foam core. However, the damage causes delamination of said plates. In addition, ingress of moisture can cause the damage to increase over time due to freezing of the moisture, which may happened repeatedly. Thus the partition wall will break down even further.
It is an object of the present invention to reduce the problem of damage resulting from an impact.
To this end, a vehicle according to the preamble is characterized in that the insulating panel is enveloped by a sleeve of flexible material wherein the sleeve is moveable relative to the insulating panel, and at the second main side facing the second compartment the partition wall module comprises at least one further plate;
wherein
- said plates are adjacent to each other and fixed to the sleeve, and
- two adjacent plates being separated from each other by a secondary seam parallel to a virtual line that is an intersection of the partition wall in the first position and of the partition wall in the second position;
wherein at least one secondary seam is present at a distance D from the virtual line, which distance D is at least 40% of the distance from the virtual line to the edge opposite of the virtual line.
It has been found that a partition wall comprising such a panel withstands abuse better than prior art partition walls.
In the present application, the term vehicle comprises both non-motorized vehicle (e.g. a trailer) and a motorized vehicle (e.g. a truck).
Typically the protection plates will have a thickness of at least
0.5 mm.
Typically the plates for protection are made of impact resistant plastic. The term impact resistant plastic refers to a material that has an impact resistance of at least 25 times the Izod impact resistance of the foam (ISO 180).
The insulating panel will typically comprise a hard foam such as PUR.
The flexible material of the sleeve will typically be made of plastic, e.g. PVC.
As at least one secondary seam is present at a distance D from the virtual line that is at least 40% of the distance from the virtual line to the edge opposite of the virtual line (and preferably at least 50% and more preferably at least 60%), this means that for a suspended partition wall module, the seam will be in or close to the bottom half, where the partition wall module is most likely to be hit.
Typically a partition wall will comprise only one partition wall module, but it may comprise more than one, such as two or three. If a partition wall comprises more than partition wall module, they can typically be in a first or second position independent from each other .
In the present application the plates at the second main side are also be referred to as secondary plates.
According to a favourable embodiment, the number of secondary seams is at least 2, more preferably at least 4.
This allows the partition wall module to withstand impact better. Of the secondary seams it is preferred that at least two and preferably at least three are present at a distance D from the virtual line that is at least 40% of the distance from the virtual line to the edge opposite of the virtual line.
According to a favourable embodiment, the secondary seam has a width of less than 1 mm, preferably less than 0.5 mm.
Thus the partition door is well protected.
The width specified above is preferably that width for all of the secondary seams, if there is more than one secondary seam.
According to a favourable embodiment, the partition wall module comprises at the first main face of the partition wall facing the first compartment at least two primary plates, adjacent primary plates being separated by a primary seam parallel to the virtual line, said primary seam having a width of at least 3 mm, preferably at least 8 mm.
This allows the partition wall to be bent without the primary plates touching each other, avoiding the risk of delamination of said primary plates. Typically the primary protection plates will have a thickness of at least 0.5 mm.
Typically the plates for protection are made of impact resistant plastic. The term impact resistant plastic refers to a material that has an impact resistance of at least 25 times the Tzod impact resistance of the foam (ISO 180).
Typically the primary seams will have a width of less than 10 cm, such as less than 5 cm and preferably less than 2 cm.
According to a favourable embodiment, said partition wall module is capable of being
- in a first position transverse to the floor, and
- in a second position parallel to the ceiling;
wherein the partition wall module is a suspended partition wall module, with the top section being rotatably fixed to at least one of i) the ceiling and ii) the longitudinally extending walls for movement of the partition wall module between the first position and the second position;
wherein the seam or seams runs parallel to the ceiling.
This is an important embodiment of the present invention.
According to a favourable embodiment, the partition wall module comprises a resilient frame, said frame encompassing at least one insulating panel.
The resilient frame will re-assume its original shape after an impact. It is for example made of fiber-reinforced plastic such as glass-fiber reinforced polyester.
According to a favourable embodiment, the frame is enveloped by the sleeve.
Thus a simple construction is provided that can resist an impact well.
Finally, the present invention relates to a method of manufacturing a partition wall comprising a partition wall module, said partition wall module having a first main side and a second main side, wherein a core comprising at least one insulating panel is provided with a plate for protecting the insulating panel;
wherein at least one of the insulating panels of the core is enveloped by a sleeve of flexible material wherein the sleeve is moveable relative to the insulating panel, wherein at least one further plate for protecting the insulating panel are attached to the sleeve is used, wherein
- said plates are adjacent to each other and fixed to the sleeve, and
- two adjacent plates being separated from each other by a secondary seam.
The partition wall is a partition wall for a vehicle for cooled t ransport.
Typically the protection plates will have a thickness of at least
0.5 mm.
Typicall the secondary seam between two adjacent plates will have a width of less than 1 mm, preferably less than 0.5 mm.
Typically the protection plates are made of impact resistant plastic. The term impact resistant plastic refers to a material that has an impact resistance of at least 25 times the Izod impact resistance of the foam (ISO 180).
The insulating panel will typically comprise a hard foam such as PUR.
The flexible material of the sleeve will typically be made of plastic, e.g. PVC.
The plates can be attached to the sleeve using any method known in the art, in particular by a bonding method such as gluing, ultrasonic welding or thermal welding.
According to a favourable embodiment, a resilient frame will be provided with at least one insulating panel, and the assembly of the resilient frame and the at least one insulating panel is subsequently enveloped by the sleeve.
Thus a strong an impact resistant partition wall can be made.
The resilient frame is for example made of fiber-reinforced plastic such as glass-fiber reinforced polyester.
According to a favourable embodiment, the first main side of the partition wall opposite of the second main side is provided with at least two primary plates for protecting the at least one insulating panel, wherein the adjacent primary plates are separated by a primary seam having a width of at least 3 mm, preferably at least 8 mm, the primary seam running parallel to the secondary seam of the plates.
Thus the insulating panels are protected at both main sides. Typically the primary seams will have a width of less than 10 cm, such as less than 5 cm and preferably less than 2 cm.
The present invention will now be illustrated with reference to the drawing where
Fig. 1Ά to Fig. ID show a cross-sectional view of a vehicle during loading;
Fig. 2A shows a cross-sectional rear view through a partition wall of the vehicle shown in Fig. 1A to Fig. ID;
Fig. 2b shows a cross-sectional side view on the partition wall of the vehicle shown in Fig. 1A to Fig. ID;
Fig. 2c shows a cross-sectional side view in detail through the partition wall of Fig. 2B; and
Fig. 3A and Fig. 3B show a front view and a rear view of the partition wall of Fig. 1A respectively.
Fig. 1A to Fig. ID show a cross-sectional view of a vehicle 100, in particular a trailer, during loading of cargo 199.
The trailer 100 comprises a cargo space 101, a closable access opening 102, a floor 103, longitudinally extending walls 104 and a ceiling 105.
The trailer 100 comprises a partition wall 150 capable of being in a first position (Fig. IB) transverse to the floor 103 and in a second position parallel to the ceiling 105 (Fig. 1Ά).
With the partition wall 150 in the second position, cargo 199' that is to be kept at -20 °C is moved to a first compartment area in the front of the trailer 100 using a forklift truck 190 (Fig. 1A).
Once the cargo 199' to be kept at -20 °C has been loaded, a load bar 180 is provided to secure the cargo 199' and the partition wall 150 is brought to the first position (Fig. IB), dividing the cargo space 101 into a first compartment 110 and a second compartment 120.
Typically the partition wall 150 is mounted on a guide 130 such as rails to provide flexible partitioning for the cargo space 101.
The second compartment 120 is loaded with cargo 199 that has to be kept at a higher temperature, here +6 °C (Fig. 1C) .
The forklift truck driver may hit the partition wall 150, typically the lower half thereof (Fig. ID; white arrow), which may cause damage to the partition wall 150.
In accordance with the present invention, however, a partition wall 150 is used which is less susceptible to damage.
Fig. 2A shows a cross-sectional rear view through a partition wall of the vehicle shown in Fig. 1A to Fig. ID.
Fig. 2A shows the floor 103, the walls 104 and the ceiling 105 of the vehicle. The ceiling 105 is provided with rails 205 for moving the partition wall 150.
The partition wall 150 comprises two lifting devices 250 for changing the position of the partition wall 150 between the first position and the second position. The lifting devices 250 are known in the art.
In the embodiment of the present invention shown here, the partition wall 150 comprises a single partition module. That is, it is not divided up in segments that can be in the first and second position independently. Hence, in this embodiment the terms partition wall and partition wall module can be used interchangeably.
The partition module 250 comprises a frame 260, comprising a first U-shaped subframe 260' and a second U-shaped subframe 260 received in the first subframe 260'. Each subframe comprises an insulating panel 270.
The subframes are connected to the lifting devices 250 via arms 251.
Fig. 2B shows that the first main side 201 of the partition wall 150 facing the first compartment 110 is provided with primary plates 210, and the second main side 202 facing the second compartment 120 with (secondary) plates 220.
Seams 221 between adjacent secondary plates 220 are relatively narrow compared to the seams 211 between adjacent primary plates 210. This allows the lower end of the partition wall 150 to bend more easily towards the first compartment 110 in case of an impact against the second main side 202.
Fig. 2C shows a cross-sectional side view in detail through the partition wall 150 of Fig. 2B. In this embodiment, the foam panels 270 are enveloped by a PVC sleeve 280 formed by sealing two sheets of PVC together .
In Fig. 2C, the parts have been shown apart (horizontally spaced) for the sake of clarity.
Fig. 2C also shows two resilient (rubber) flaps 290 extending over the width of the partition wall 150, which serve to seal the gap between the first compartment 110 and the second compartment 120 present at the floor 103.
Fig. 3A and Fig. 3B show a front view and a rear view of the partition wall of Fig. 1A respectively. The primary plates 210 face the first compartment 110 and the secondary plates 220 face the second compartment 120. The lifting devices 250 lift the partition wall 150 via the arms 251. To move the partition wall 150, the upright walls 104 are provided with rails 130.
