Definitions
- the present invention relates to a curtain locking system and in particular to a curtain locking mechanism for locking the curtains of curtain-sided trucks and trailers.
- the present invention provides a curtain locking mechanism for locking the curtain of curtain-sided trucks or trailers, the locking mechanism including: a curtain hook adapted for attachment to the curtain; a latch assembly adapted for actuation between an unlocked configuration and a 5 locked configuration; wherein, in the unlocked configuration, the hook is disengagable from the latch assembly and, in the locked configuration, the latch assembly engages and moves the hook to a position applying tension to the curtain.
- the present invention provides a curtain-sided truck or trailer 0 including: a curtain having a plurality of straps attached at intervals along the length of the curtain; a plurality of hooks respectively attached to each of the plurality of straps; a latch assembly adapted for actuation between an unlocked configuration and a S locked configuration; wherein, in the unlocked configuration, the hooks are disengagable from the latch assembly and, in the locked configuration, the latch assembly engages and moves the hooks to positions applying tension to the curtain.
- the latch assembly includes a shaft driven to pivot between the locked configuration and the unlocked configuration, the shaft having a crank adapted to engage the hook in the locked configuration.
- the latch assembly includes a latch bar or plate adapted for linear movement between the unlocked and locked configurations, the bar or plate adapted to engage the hook in the locked configuration.
- the mechanism includes a plurality of hooks spaced at intervals along the curtain and the latch assembly is adapted to simultaneously engage and move each of the hooks when actuated to the locked configuration.
- the latch assembly includes a shaft having a plurality of cranks, each crank corresponding to and adapted to engage one of the hooks.
- the curtain includes one or more slots and the hook is shaped to weave through the one or more slots.
- the hook is attached to a curtain strap, the curtain strap being stitched or welded to the curtain. Further preferably, the hook is attached to the curtain strap by means of an adjustment device.
- the adjustment device includes a top portion attached to the curtain strap, a bottom portion attached to the hook and a threaded shaft received at either end of the top and bottom portions, wherein rotation of the threaded shaft in one direction contracts the top and bottom portions together and in the other direction expands the top and bottom portions apart.
- the latch assembly includes drive means to actuate the latch assembly between the locked and unlocked configurations.
- the drive means is a ram.
- the ram is a pneumatic ram.
- the ram is an hydraulic cylinder.
- the latch assembly further includes a lever arm extending from the shaft, the ram being attached to the lever arm. Further preferably, the latch assembly includes a plurality of rams adapted to simultaneously drive actuation of the latch assembly.
- Figure 1 is a cross sectional schematic drawing of a curtain-sided truck or trailer incorporating an embodiment of a curtain locking mechanism according to the present invention
- Figure 2 is a cross sectional view similar to that of Fig. 1, showing a first embodiment of a latch assembly for the curtain locking mechanism;
- Figure 3 is a partial side view of the curtain-sided truck or trailer shown in Fig. 1;
- Figure 4 is a cross sectional view similar to Fig. 2, showing a second embodiment of a latch assembly for the curtain locking mechanism.
- Fig. 1 is a schematic drawing of an embodiment of a curtain locking mechanism 10 according to the present invention.
- the mechanism 10 includes a hook 12 and latch assembly 14.
- the mechanism 10 is adapted for installation below the base 16 of the truck or trailer.
- the latch assembly 14 comprises a drive means 18, in the form of a pneumatic ram, adapted to pivot a shaft 20.
- the ram 18 is pivotally connected to a lever arm 22 of the shaft 20.
- the latch assembly 14 further comprises a crank 24 on the shaft 20 adjacent the hook 12.
- the hook 12 is attached to the curtain 26 by means of a length adjustment device 28 and a curtain strap 30.
- the curtain strap 30 is attached at one end to the curtain 26, such as by welding or stitching, and attached to the hook 12 at the other end via the adjustment device 28.
- the latch assembly comprises a drive means 18, in the form of a pneumatic ram, adapted to extend and retract a locking bar 25.
- a locking plate (not shown) may be employed as an alternative to the locking bar.
- the latch assembly 14 can be moved between a locked configuration and an unlocked configuration. In the locked configuration shown in Figs. 2 and 4, the latch assembly 14 engages the hook 12. In the unlocked configuration, shown in phantom in Figs. 2 and 4, the latch assembly 14 is disengaged from the hook 12.
- the ram 18 drives the lever arm 22, which rotates the shaft 20 such that the crank 24 engages and moves the hook 12 into a position applying tension to the hook 12 (in the direction of arrow A).
- FIG. 3 there is shown an embodiment of the truck or trailer incorporating a curtain locking mechanism 10 including a plurality of hooks 12.
- the shaft 20 has a corresponding plurality of cranks 24 adjacent each of the hooks 12.
- Each crank 24 is adapted to simultaneously engage the corresponding hook 12, when the shaft 20 is pivoted by actuation of the latch assembly 14 to the locked configuration.
- the curtain 26 is provided with a plurality of slots 32 corresponding to each hook 12.
- the hooks 12 are received and located through the respective slots 32.
- the profile of each hook 12, as depicted in Fig. 2, is undulated corresponding to the respective slot 32, to assist in securing the hook 12 relative to the curtain 26. This helps maintain each of the hooks 12 in a consistent position whenever the latch assembly 14 is in the unlocked configuration. In turn, this assists in obtaining correct engagement of the hooks
- the adjustment devices 28 comprise a top portion 34 attached to the curtain strap 30, a bottom portion 36 attached to the hook 12 and a threaded shaft 38 received at either end by the top 34 and bottom 36 portions. Rotation of the threaded shaft 38 in one direction contracts the top 34 and bottom 36 portions together and in the other direction, expands the top 34 and bottom 36 portions apart.
- the adjustment devices 28 are provided to allow the user to adjust the effective length of the hook 12/curtain strap 30 arrangement. This allows initial alignment of the hooks 12 with the cranks 24 for the desired curtain tension, as well as readjustment of the hooks 12 should any become loose or overly tight.
- the curtain locking mechanism 10 allows the user to lock down all of the curtain straps 30 by operation of, for example, a single switch. This greatly reduces the time and effort involved in manually locking down each strap individually.
- the truck or trailer may comprise a number of isolated mechanisms, such that individual mechanisms, or individual groups of mechanisms, can be operated selectively and separately to the other mechanisms. Accordingly, single hooks or groups of hooks can be selectively engaged or disengaged in isolation to others.
