20185453 prh 03 -04- 2019
TECHNICAL FIELD OF THE INVENTION
The invention relates to a load unit arrangement having first and second load units to be carried by a vehicle, such as by a truck. In particularly the invention relates to a load unit arrangement, where the first and second load units can be moved in relation to each other and connected to and disconnected from each other and where the load unit arrangement comprises a braking arrangement for braking or stopping the movement of the load units.
io
BACKGROUND OF THE INVENTION
It is known to transport a skip or interchangeable load unit by a vehicle, such as a truck, unload or remove the load unit off the vehicle and then load another load unit to the vehicle. It is also known to transport a load system 15 having first and second load units connected to each other, so loaded them on the top of each other.

The landing device is arranged between a first 20 end of the first load unit and a second end of the second load unit so that a first portion of said landing device is supported to the first end of the first load unit and a second portion of said landing device is supported to the second end of the second load unit. The landing device is configured to move said first end of said first load unit into the lower lever than the second end of the 25 second load unit after said first end of the first load unit has met said second end of the second load unit.
DE 19640977 A1 discloses a dolly for transporting containers, particularly rolling containers, pallets or the like, on a platform, in which the containers are located adjacent and row-wise. The containers rollers can move along 30 platform tracks and the trolley rails comprise U-profiles to take the container rollers. The dolly is provided with stops to prevent the containers rolling over crossways and the dolly itself takes two levels of containers with the aid of
20185453 prh 03 -04- 2019 angle rails on the trailer sidewalls so that these can form a second track for the upper level etc trolley rollers. The dolly is equipped with a tow rope for moving the dolly on the platform.

NL 1028521 A1 discloses a truck or trailer for transporting container and having a loading device with follower connected to a braking device and load pulling device. The vehicle comprises a frame with a load support surface for 15 a load such as a container or load compartment. The loading device is used to pull the load onto this surface and comprises a pulling device movable in a pulling direction. A load grip means is provided at one end of the pulling device and the other end is connected to a driven winch.
However, the problem there is to disconnect the load units, so to take the 20 upper load unit away from the top of the bottom load unit and lowering the upper load unit to the ground in an easy and controlled way. For example, one must be sure that the upper load unit would not slide in an uncontrolled manner and thereby would not cause dangerous situation. The problems are for example to control the sliding of the top load unit, such as braking or 25 stopping the movement of the top load unit so that the top load unit would not drop off from the rear end of the bottom load unit.
SUMMARY OF THE INVENTION
An object of the invention is to alleviate and eliminate the problems relating 30 to the known prior art. Especially the object of the invention is to provide an arrangement for controlling the moving of the top load unit so that it would not cause any dangerous situations and in particularly so that the top load unit would not drop off from the rear end of the bottom load unit. In addition the object is to provide an arrangement so that the moving of the top load unit
20185453 prh 03 -04- 2019 can be braked or stopped.
The object of the invention can be achieved by the features of independent claims.
The invention relates to load unit arrangement according to claim 1. In 5 addition the invention relates to load units to be used in the load unit arrangement according to claims 18 and 19.
According to an embodiment of the invention a load unit arrangement comprises at least first and second load units, which can be carried by a vehicle, such as a truck for example. Both the load units have first and second io ends, so rear and front ends, and longitudinal axis between said first and second ends. The load units are configured to move in relation to each other in a first longitudinal direction to disconnect the load units and in a second longitudinal direction to connect the load units. The second longitudinal direction is essentially opposite to the first longitudinal direction and 15 essentially parallel to said longitudinal axis of the load units, when the second load unit is essentially wholly on the top of the first load unit. It is to be noted that the angle between the moving directions (the first and second longitudinal directions) and longitudinal axis changes when the second load unit slides to the first longitudinal direction.
In addition it is to be noted that when the second load unit is essentially wholly on the top of the first load unit, the longitudinal axles of the load units have a first mutual angle which is close to zero degrees (so the longitudinal axles are essentially parallel in this situation).
According to an embodiment the second load unit comprises a guiding 25 member and the first load unit comprises a guiding rail, along which the guiding member of the second load unit and thereby the second load unit is configured to move in said first and second longitudinal directions during said relational movement of said first and second load units. The guiding rail may comprise for example a groove or slot or implemented by an L or U shaped 30 bar, the longitudinal axis of which extends essentially in the first longitudinal direction. The guiding rail advantageously comprises a projection surface on a top portion of the guiding rail so in the portion which is closest to the second load unit when the second load unit locates on the top of the first load unit. The projection surface is configured to limit the movement of the guiding
20185453 prh 03 -04- 2019 member of the second load unit in a transverse direction being essentially perpendicular to the longitudinal axis of the first load unit and thereby to prevent the movement of the guiding member towards said second load unit moving on the top of the first load unit.
According to an embodiment the second load unit additionally comprises a braking arrangement which is configured to be mechanically introduced to the first load unit and thereby to prevent an angle change of the mutual angle of the longitudinal axles of the load units over a second angle during said relational movement of said first and second load units. It is to be noted that io the magnitude of the second angle increased when the second load unit moves in said first longitudinal direction, because otherwise it might be that the guiding member cannot come out from the end of the guiding rail. In addition it is to be noted that the second angle has a local maxima in each point in said longitudinal axis of the first load unit and that the value of the 15 maxima increases in said first longitudinal direction.
The braking arrangement can be used for preventing the angle change of the mutual angle of the longitudinal axles of the load units over a second angle and thereby to brake or stop the movement of the second load unit. The controlling can be done for example by lifting or lowering the first end of the 20 first load unit, whereupon the angle of attack of the braking arrangement in relation to the first longitudinal axel of the first load unit (or the guiding rail or the projection surface of the guiding rail) can be controlled between the first and second angles so that when the angle of attack is essentially same or bit greater than said first angle, the second load unit can move relatively easily, 25 and when the angle of attack is essentially same or bit smaller than said second angle, the movement of the second load unit is braked. When the first end of the first load unit is lifted upwards (or when the second load unit has moved enough in said first longitudinal direction), the angle of attack of the braking arrangement will reach the second angle, whereupon the braking 30 arrangement will brake and stop the movement of the second load unit in relation to the first load unit.
According to an embodiment the braking arrangement comprises at least first and second supporting points configured to be supported to the first load unit. Advantageously the first and second supporting points are configured to be 35 supported to the first load unit so that the first supporting point is supported to the projection surface of the guiding rail and said projection surface locates
20185453 prh 03 -04- 2019 between said first and second supporting points, or even so that both the first and second supporting points are configured to be supported to the projection surface so that said projection surface locates between said first and second supporting points.
The supporting points are configured to be supported in a movable manner in relation to said first load unit and allowing the moving of said first and second supporting points in relation to the first load unit essentially in said first and second longitudinal directions, and where the relational positioning of said first and second supporting points mechanically prevents said angle io change of the mutual angle of the longitudinal axles of the load units over a second angle, when said first and second supporting points are supported to the first load unit.
The supporting points can be implemented in different ways, such as by protruding members like pins or elongated surface, such as by a slide or 15 blade. The pins can slide often easily whereas the pressure induced by the supporting points for example to the guiding rail or projection surface can be spread to larger area by the elongated surface. In addition also a curvature surface can be used in particularly in the second supporting point.
According to an embodiment the braking arrangement is fixed to the second 20 load unit by a hinge so that the braking arrangement can turn around the hinge. The hinge may have a limited opening angle. The arrangement, or the second load unit, may also comprise an actuating member, such as a spring or cylinder, by which the braking arrangement can be turned around the hinge, thereby forcing at least one of the first or second supporting points to 25 be pressed against the first load unit, against the guiding rail or against the projection surface.
In addition, according to an embodiment the load unit arrangement additionally comprises a stopping arrangement, which is configured to stop the mutual movement of the first and second load units before the first end of 30 the second load unit meets the second end of the first load unit when the second load unit is moving in said first direction.
The present invention offers advantages over the known prior art, such as enables very easy, fast and safe arrangement especially for disconnecting the load units, so to move the upper load unit away from the top of the bottom
20185453 prh 03 -04- 2019 load unit by sliding the upper load unit in a controllable manner. In addition the invention makes it possible to brake or limit the relational movement of the upper load unit and even stop the moving of the first load unit on the top of the second load unit, thereby making the arrangement safe to use.
According to embodiments the sliding (so the braking and/or stopping) of the upper load unit can be controlled e.g. by lifting or lowering the first end of the first load unit, so i.e. by changing the attack of angle of the braking arrangement in relation to the first load unit longitudinal axis.
The exemplary embodiments presented in this text are not to be interpreted io to pose limitations to the applicability of the appended claims. The verb to comprise is used in this text as an open limitation that does not exclude the existence of also unrecited features. The features recited in depending claims are mutually freely combinable unless otherwise explicitly stated.
The novel features which are considered as characteristic of the invention are 15 set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific example embodiments when read in connection with the accompanying drawings.

DETAILED DESCRIPTION
Figures 1A-1C illustrate a principle of an exemplary load unit arrangement 100 for disconnecting first and second load units 101,102 carried by a vehicle 117, where the load unit arrangement comprises the braking arrangement according to an advantageous embodiment of the invention. The load units have first and second ends 101 A, 101B, 102A, 102B and longitudinal axis ίο 105A, 105B between said first and second ends.
The load units 101, 102 are configured to move in relation to each other in a first longitudinal direction 113 to disconnect the load units and in a second longitudinal direction 114 to connect the load units. The second longitudinal direction is essentially opposite to the first longitudinal direction and 15 essentially parallel to said longitudinal axis of the load units, when the second load unit 102 is essentially wholly on the top of the first load unit 101. It is to be noted that when the second load unit 102 is essentially wholly on the top of the first load unit 101, the longitudinal axles 105A, 105B of the load units have a first mutual angle 105C which is close to zero degrees (so the 20 longitudinal axles are essentially parallel in this situation). ‘
However, when the second load unit 102 moves in the first longitudinal direction 113, the mutual angle between the first and second longitudinal axles 105A, 105B increases, as can be seen in Figures 2B-2C. In Figure 2B the stopping arrangement (arranged in a third portion 102C of the second 25 load unit 102) is stopped the movement of the second load unit 102 and the moving of the second load unit 102 can be continued only when the angle of attack is increased enough (see detailed description in connection with the Figures 4A-4B). After the angle is changed big enough (the mutual angle is greater than the third angle 105E and equal to or smaller than said second 30 angle 105D), the second load unit 102 can continue the movement in the first longitudinal direction 113, as is the case in Figure 1C.
In all positions the braking arrangement can be used for preventing the angle change of the mutual angle of the longitudinal axles 105A, 105B of the load units over the second angle 105D and thereby brake or stop the movement
20185453 prh 03 -04- 2019 of the second load unit 102. The controlling can be done for example by lifting or lowering the first end 101A of the first load unit 101, whereupon the angle of attack of the braking arrangement 103 in relation to the first longitudinal axel 105A of the first load unit (or the guiding rail or the projection surface 108 of the guiding rail) can be controlled between the first and second angles
105C, 105D so that when the angle of attack is essentially same or bit greater than said first angle 105C, the second load unit 102 can move relatively freely and easily along the guiding rail 106, and when the angle of attack is essentially same or bit smaller than said second angle 105D, the movement io of the second load unit 102 is braked. When the first end 101A of the first load unit 101 is lifted upwards (or when the second load unit 102 has moved enough in said first longitudinal direction 113), the angle of attack of the braking arrangement 103 will reach the second angle 105D, whereupon the braking arrangement 103 will brake and even stop the movement of the 15 second load unit in relation to the first load unit. The stopping can be achieved in any positions so that braking arrangement 103 reaches the second angle 105D and the supporting points causes a momentum and thereby a friction force between the supporting points and the supporting structure (the first load unit 101, guiding rail 106 or projection surface 108), which is greater than 20 the component of the dragging force in the first longitudinal direction 113 caused by the gravitation to the second load unit 102.
Figures 2A-2D illustrate an exemplary braking arrangement 103 according to an advantageous embodiment of the invention. The first load unit 101 comprises a guiding rail 106 (shown e.g. in Fig 2A and 2C) and the second 25 load unit 102 a guiding member 104, which are arranged so that the guiding rail 106 receives the guiding member 104 and allows the guiding member 104 to move along the guiding rail 106 in said first and second longitudinal directions 113, 114 during the relational movement of said first and second load units. The guiding rail 106 advantageously comprises a projection 30 surface 108 on a top portion of the guiding rail 106, which is configured to limit the movement of the guiding member 104 of the second load unit 102 in a transverse direction 107 being essentially perpendicular to the longitudinal axis 105A of the first load unit 101.
The second load unit 102 advantageously comprises the braking 35 arrangement 103, which is configured to be mechanically introduced to the first load unit 101 and thereby to prevent an angle change of the mutual angle
20185453 prh 03 -04- 2019 of the longitudinal axles 105A, 105B of the load units over the second angle 105D during the relational movement of said first and second load units 101, 102. As said elsewhere in this document, it is to be noted that the magnitude of the second angle 105D increased when the second load unit 102 moves in said first longitudinal direction 113.
The first example of the braking arrangement 103 is depicted in more details in Figures 2A-2D, where the braking arrangement 103 comprises first 104, 109 and second 112 supporting points. It is to be noted that there might be one or two or more first supporting points 104, 109, whereupon one of the io first supporting point 104 can be used as the said guiding member 104 of the second load unit 102. In addition it is to be noted that even if the protruding members 104, 109, 119 are depicted here, the elongated surface, such as by a slide or blade can also be used.
Advantageously the supporting points are configured to be supported to the 15 first load unit 101 so that the first supporting point 104, 109 is supported to the projection surface 108 of the guiding rail 106 so that the projection surface 108 locates between the first 104, 109 and second 112 supporting points.
Also the second supporting point 112 may be supported to the projection surface 108 so that the projection surface 108 locates between the first and 20 second supporting points.
In the exemplary braking arrangement 103 illustrated in Figures 2A-2C the second supporting point 112 is implemented by a curved surface 112, which is configured to be mechanically introduced to first load unit or the guiding rail or advantageously to the projection surface 108 opposite to the first 25 supporting point 104, 109. When the second load unit 102 moves in the first longitudinal direction 113, the angle of attack increases, whereupon the angle 118 between the end wall in the first end 102A of the second load unit 102 decreases. Thus, the different portion of the curved surface 112 is introduced to the projection surface 108 when the magnitude of the second angle 105D 30 increased or the angle of attack increased (or when the angle 118 between the end wall in the first end 102A of the second load unit 102 decreases).
Therefore, it is advantageous to have the curved surface 112 in said second supporting point 112 that the pressure is spread more uniformly even if the angles change during the relational movement of the first and second load 35 units 101, 102.
20185453 prh 03 -04- 2019
Figures 3A-3B illustrate another exemplary braking arrangement 103 according to an advantageous embodiment of the invention, where there is only one first supporting point 104 and one second supporting point 119. Also in this embodiment the first supporting point 104 can be used as the guiding 5 member 104 of the second load unit 102. Advantageously the first supporting point 104 is arranged to the braking arrangement 103 to the first longitudinal direction 113 from the second supporting points 119, as can be seen especially in Figure 3A.
As is illustrated in Figures 2D and 3A, the braking arrangement 103 may be io fixed to the second load unit 102 by a hinge 120 so that the braking arrangement 103 can turn or be turned around the hinge 120. The arrangement may also comprise an actuating member 110, such as a spring or cylinder, by which the braking arrangement 103 can be turned around the hinge, thereby forcing at least one of the first or second supporting points 104, 15 109,112,119 to be pressed against the first load unit 101, against the guiding rail 106 or against the projection surface 108, and thereby limit the angle range so in practice the maximum value of the second angle 105D.
Figures 4A-4B illustrate an exemplary stopping arrangement 115 according to an advantageous embodiment of the invention, which is configured to stop 20 the mutual movement of the first and second load units 101, 102 before the first end 102A of the second load unit 102 meets the second end 101B of the first load unit 101 when the second load unit 102 is moving in said first direction 113.
The stopping arrangement 115 comprises advantageously at least a first and 25 second protrusion members 111, 116. The first protrusion member 111 is arranged to the second end 101B of the first load unit 101 and the second protrusion member 116 is arranged in a third portion 102C, typically slightly to the second longitudinal direction 114 from the center line locating middle between the first and second ends 102A, 102B of the second load unit 102.
By this it can be ensured that different sized load units can be disconnected and connected and in particularly so that the second end 102B of the second load unit 102 reach the ground when the second load unit 102 is moving to the first longitudinal direction 113. Typically the second end 102B of the second load unit 102 reach the ground when the stopping arrangement stops 35 the movement and at least when the first end 101A of the first load unit 101 is lifted upwards (whereupon the second end 102B of the second load unit
102 is lowered downwards).

The first and second protrusion members 111, 116 are arranged so that they are introduced with each other before the first end 102A of the second load unit 102 meets the second end 101B of the first load unit 101 when the second load unit 102 is moving in said first direction 113 therefore preventing and stopping the mutual movement, when said mutual angle of the longitudinal axles 105A, 105B of said first and second load units 101, 102 is at maximum a third angle 105E. The third angle 105E is equal to or greater than said first io angle 105C but smaller than said second angle 105D at the point where the first and second protrusion members 111, 116 meet each other (Figure 4A).
When the angle of attack is changed (e.g. by lifting the first end 101A of the first load unit 101 and so that the second end 102B of the second load unit 102 hits the ground) so the mutual angle of the longitudinal axles 105A, 105B 15 of said first and second load units 101, 102 is greater than said third angle 105E and equal to or smaller than said second angle 105D, the first and second protrusion members 111,116 can overtake each other, as is depicted in Figure 4B. In this way the stopping arrangement 115 can release the second load unit 102 and allowing it 102 to move further to the first 20 longitudinal direction 113.
The invention has been explained above with reference to the aforementioned embodiments, and several advantages of the invention have been demonstrated. It is clear that the invention is not only restricted to these embodiments, but comprises all possible embodiments within the spirit and 25 scope of the inventive thought and the following patent claims.
The features recited in dependent claims are mutually freely combinable unless otherwise explicitly stated.
