Definitions
- Conventional side curtains on truck and trailer bodies are retained along the top edge on a rail system extending along the roof of the body in a manner whereby the curtain may be slid between the ends of the body.
- the curtain is wrapped around a vertical pipe and the pipe is rotatable by a ratchet mechanism to tension the curtain in a horizontal direction.
- the curtain is tensioned in a vertical direction by a large number of closely spaced straps and buckles with hooks that engage underneath the coaming rail of the body. In the case of a 48 foot long trailer there is as many as 22 such straps.
- These straps and buckles require a significant amount of time to attach and tension, considerably increasing the time to load and unload a curtain sided truck or trailer.
- the present Applicants have invented a side curtain having a bottom edge in the shape of a series of intersecting arcs (preferably three) and the curtain is tensioned in a vertical direction at the intersection of the arcs (see pending International Patent Application No. PCT/AU2008/000129 in the name of the present Applicants).
- the object of the present invention is to provide a tensioning device for tensioning side curtains such as that of Applicants' aforementioned International patent application, as well as being suitable for other purposes.
- the invention provides a tensioning device for tensioning a truck or trailer side curtain in a vertical direction, said device comprising an arm member having a hook at one end and being mounted in a frame to move initially from a retracted position, under a floor of the truck or trailer body, to an extended position wherein it projects beyond a perimeter edge of said floor, said arm member being further adapted for pivotal movement to pivot downwardly from said extended position to a final position, whereby engagement of said hook with a side curtain in said extended position causes vertical tension to said curtain as a result of said pivotal movement to said final position.
- Figure 1 is a schematic side elevational view of a tensioning device according to the invention in a retracted position (parts have been removed for clarity);
- Figure 2 is similar to Figure 1 but shows the device in an intermediate stage of operation;
- Figure 3 is similar to Figures 1 and 2 but shows the device in the final position of operation in tensioning a side curtain
- Figure 4 is similar to Figure 3 but shows the device in the final position of operation with locking catch engaged.
- the device 10 is constructed as a separate and complete device which is readily attached to the underside of a truck or trailer body (not shown).
- the device 10 consists essentially of a hook 11 which is arranged at one end of an elongate arm 12 at the other end of which is an integral crank 13.
- the hook 11 has an elongate finger 14 depending therefrom.
- the hook member 11 pivots on a shaft 16 extending between opposed side plates 17, only one of which is shown in Figures 1 to 3.
- the shaft 16 is located in opposed slots 15 in the respective side plates 17 and is able to slide therein as will be apparent hereinbelow.
- a pneumatic cylinder 23 is mounted on a web 24 extending from an end plate (not shown) of the device and is able to pivot thereon by means of pivotal connection 25.
- the actuating shaft 18 of the cylinder 23 is connected to the crank 13 by a pin 26.
- the pin 26 extends between the opposed side plates 17 and each end of the pin 26 is located in a slot 19 in the respective side plates.
- a compression spring 27 is located on the shaft 18 and is compressed between the end of the cylinder 23 and a washer 28 which is retained on the shaft by lock-nuts 20.
- a stop member 29 extends downward from a top plate 21 of the device and serves to engage the washer 28 when the shaft 18 is extended under the force of spring 27 (see Figure 2).
- a manually operated locking catch 29 is mounted on a side plate 17 by means of a pin 30 located in slot 31 and has a handle 32 which is parked in slot
- the catch 29 has a hooked end 34 for engaging a pin 35 at the end of finger 14 when the device is in a fully extended position applying tension to a side curtain.
- Compressed air is supplied to the cylinder 23 from an actuating valve (not shown) via ports 36 of the cylinder 23.
- the actuating valve has three positions as will be apparent hereinbelow.
- the complete assembly may be fixed to the underside of a truck or trailer floor so that the device extends transversally of the truck or trailer longitudinal direction, and the outer end of the side plates 17 are approximately flush with the perimeter outer edge of the trailer floor (not shown).
- an operator switches the actuating valve (not shown) from a 'release' position to a 'centre' position whereby pressure in cylinder 23 is exhausted and the spring 27 causes the actuating shaft 18 of cylinder 23 to remove to the position shown in Figure 2.
- This causes the pin 16 to slide in grooves 15 and pin 26 to slide in grooves 19 whereby the arm 12 moves from the retracted position to the extended position shown in figure 2.
- the operator is able to check the relative positions of the rope or cable 37 and the hook 11 by walking along the side of the truck or trailer body. This is to ensure the rope or cable is in the correct position for engagement by the hook 11 in the next stage of operation.
- the locking catch 29 may be manually moved from the position shown in Figure 1 to the position shown in Figure 4 so that it engages the finger 14 and holds the arm 12 in the fully extended or final position. As such, any loss of pneumatic pressure in cylinder 23 will not cause release of vertical tension in the side curtain.
- the tensioning device of the present invention provides a novel and automatic device for tensioning a trailer side curtain and the device is particularly suitable for a side curtain as described in Applicants' aforementioned International patent application. It should however be appreciated that the tensioning device may be applied to many other forms of side curtain as it is only necessary for the curtain to have some means such as a hole, hook, eye, rope or cable which can be engaged by the hook of the tensioning device. Clearly a number of such tensioning devices would be provided along the length of a truck or trailer floor and it is conceivable that the tensioning device could be readily adapted to other applications besides trailer side curtains.
