Description
~ ~ f~ . JJ b~
The present invention relates to the field of transport equipment. In particular, the present invention provides a device for the automated reeling in and storage of cargo tie-down strapsO
When cargo is loaded onto a flat deck, it is usually held in place for transport by means of wide woven textile belts or straps.
When cargo has been unlashed of its tie-down straps, these must then be rolled up into tight coils for storage. The rolling of these long straps into neat, tight rolls, is a time-consuming and labour intensive process. As a result, a transport company ends up paying rates equal to the total of the rental of a complete transport rig and the hourly pay of a driver for a task which virtually requires little skill, just time.
The object of the present invention is to provide a device 1~ that automatically and efficiently rolls up such cargo tie-down straps into neat rolls for storage.
In a broad aspect, the present invention relates to a cargo strap winder for a cargo strap having one free end and one end provided with securing means, said cargo strap being adapted for attachment to a -vehicle and including: ~a) a drum; (b) means for releasably securing the free end of a cargo strap to the drum,(c) ~, ri f~ f7 powered means for rotating the drum about its axis; and (d) means for enabl.ing the said powered means.
In drawings which illustrate the present invention by way of example:
Figure 1 is a perspective view of a cargo strap winder embodying the present invention;
Figure 2 is a perspective view of the device of Figure 1, with the external casing removed;
Figure 3 is a detail of the off-on mechanism of the device lO of Figure 1;
Figure 4 is the same view as Figure 2, with a cargo strap entirely wound onto the device illustrated.
Referring first to Figures 1 and 2, the device of the present invention is an automatic cargo strap winder which is 15 provided with a base 1 that may be mounted, for instance, on the side edge of a truck bed by means of nuts and bolts or welding.
Extending up from the front edge of the face 1 is a face plate 3, which includes integral gusset-shaped supports 3a welded to the base 1. A weather proof cover 2 is securable to base 1, 20 around the side and rear edges thereof and around the edges of face place 3. Cover 2 is preferab].y made o- a weather resistant material like stainless steel, and is provided with a suitable weather resistant seal, such as a silîcone gasket, at its interface with the base 1 and the face plate 3. Bolts and nuts 25 are provided for securing the cover 2 is place.
7 J t`) '.~
An electric motor 4, such as a 12 volt, one-twentieth hp ~C
motor, capable of 30 in-lb torque at 90 rpm, is mounted to the face plate 3. Between the motor 4 and the face plate 3 may be mounted a reducing gear 4a to provide additional torque, and slow down the speed of rotor 5, which is driven by motor ~ (directly or through gear 4a).
Drum 6 is mounted on rotor 5, coaxial therewith. Drum 6 is provided with at least one slot 7 to accept a cargo strap.
It will be noted that drum 6 tapers slightly from its end near face plate 3, axially away therefrom. This taper assists in removing a cargo strap from the drum after it has been wound thereon. Also, it will be noted that the outer surface of drum 6 is preferably quite smooth.
Aetuation of said motor 4 is by means of a switch 8 mounted on the base 1 below the motor switch 8 is a push button switch whieh must be he]d in a depressed state for power to flow therethrough. Power lines 16 connect the switeh 8, the motor 4, and the vehicle's electrical system.
Switch 8 is depressible by cam 9 which is mounted for partial rotation on camshaft 13 that rotates in eamshaft easing 15 extending through the face plate 3. Also mounted on camshaft ~J ~;3 ~f`~
13, on the other si~e of the faceplate 3 is a block lla, rom which a guide lever ll e~tends.
Guide lever ~1 is provided with a slot 12 through which a cargo strap may be threaded. The cargo strap will then be aligned with the slot 7 on the drum 6.
Referring to Figure 3~ an ex~ension spr~ng 10 is provided, extending between a post 14 on the cam and a notch 14 on a plate 14b extending inwardly from face plate 3. It will be observed that the cam 9 will be able to move from the gusset 3a to the switch 8. At these two pointsl the sprin~ will be drawn in, and to move from the gusset 3a to the switch or vice versa will require extension of the spring.
Therefore, when placed in either end position, some force is required to move the cam to the other. It will be understood then that when lever 11 is pulled down, it will be held down by the action of spring 10, and the cam will be pressed against the switch 8, causing activation of the motor. Pushing the lever to the up position will move the cam and deactivate the motor.
To use the device of the present invention, a strap is threaded through slot 12 on guide lever 11, which will be in the up position, and then the strap is threaded or slid into slot 7 on drum 6. The lever ll is then pulled down, bringing cam 9 into engagement with switch 8, to turn the motor 4 on. Actlon of the 2é~3.~
motor causes the drum 6 to rotate, thereby winding up the strap.
At the end of a cargo strap is a buckle or loop L (see Figure 4).
When this ]oop L strikes lever 12 and is pulled against same by rotation of drum 6, it will pull lever 12 to the up position, thereby disengaging cam 9 from switch 8, and turning off the motor. Therefore, it will be understood that it is not necessary that the operator stand by to turn off the device once a strap is wound onto the drum 6. This is automatic.
Once the device is turned off automatically, as described above, the strap is pulled off the drum, a process facilitated by the smooth surface and taper of the drum. The strap i5 then disengaged from the slot on the guide lever, a process facilitated by the large gap in that slot, and stored in an appropriate receptacle. The next strap to be stored can now be threaded onto the present device and wound up. It will be noted, though, that a minimum of time is required for this to be done, as the operator will have been given the opportunity to bring the next strap over to the device of the present invention while the device was winding up the previous strap and turning itself off.
The foregoing precess is repeated until all cargo straps have been wound up and stored.
It is to be understood that the examples described above are not meant to limit the scope of the present invention. It is expected that numerous variants will be obvious to the person ~ ~ ~, 3 ~
skilled in the cargo haulage equipment design ~rt, without any departure from the spirit of the present invention~ The appended claims t properly construed, form the only limitation upon the scope of the present lnvention.
