Description
SEMI-TRAILER LOCKING APPARATUS
FIELD OF THE INVENTION
This invention relates to apparatus for locking semi-trailers and/or freight delivery units.
BACKGROUND OF THE INVENTION
In the trucking industry, it is important that the contents of semi-trailers are secure from theft.
The most common approach has been to padlock the doors of the semi-trailer.
Unfortunately, the lock remains accessible to thieves, who are able to cut the padlock with a pair of pliers or common tools.
Once this has been done, the thieves are able to gain access to the freight seal, which is a one time locking device made from plastic or steel (cable or pin shaped) with random numbers or bar codes that are recorded by shippers or receivers at the time the contents are loaded. If the freight seal is breached in any way, the broken seal gives proof that the contents of the delivery unit have been tampered with. This includes both missing freight as well as contamination of freight.
As a result the receiver and shipper will refuse delivery of the contents of the semi-trailer.
It would be advantageous to have an apparatus for locking the doors of semi-trailers where the freight seal would be inaccessible to thieves.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a locking apparatus which provides improved protection for the contents of semi-trailers and/or freight delivery units.
It is the objective of this invention to provide a lockable apparatus that completely covers and hides any type of freight seal commonly used by shippers and receivers to identify their freight.
According to one embodiment of the invention, there is provided a locking apparatus for locking semi-trailer or freight delivery unit doors, comprising a housing having a top cover portion and a bottom potion which are secured with a high security lock. Inside the housing is a movable upper plate and a fixed lower plate. The swing bar of the semi-trailer door is placed behind the upper plate and lower plate and the freight seal is inserted through the respective holes in the upper plate and lower plate to prevent movement of the swing bar and to prevent movement of the upper plate and lower plate.
According to a further embodiment of the invention there is shown a locking apparatus for locking semi-trailer or freight delivery unit doors, comprising (a) housing means affixed to the door of a semi-trailer; (b) plate means located within said housing means for receiving a swing bar of the semi-trailer door, said plate means having a channel through which a freight seal can be inserted, whereby the freight seal is not visible from the exterior of the locking apparatus.
According to a still further embodiment of the invention there is shown a locking apparatus according to claim 1 wherein said plate means comprises (a) a first plate movably attached to the housing means; (b) a second plate fixed to the housing means, such that the first plate can be rotated to permit the swing bar to be placed behind the first and second plate and, when the freight seal is inserted through the channel, the first and second plates do not move.
According to a still further embodiment of the invention there is shown a locking apparatus wherein the housing means includes channel means through which a locking means may be used such that the freight seal is inaccessible from the exterior of the locking apparatus.
Advantages of the invention are that the freight seal is inaccessible to thieves by being located in the housing of the locking device.

3 DETAILED DESCRIPTION
Referring to Figure 1, there is shown a locking device 2 comprising a top cover portion 4 and a bottom base portion 6 in closed unlocked position. The top cover portion 4 and the bottom base portion 6 are hingedly connected along their top edges by a hinge 8. The bottom edge of the top cover portion 4 is shaped to form a handle 7.
The bottom base portion 6 has a small raised ridge 24 completely along its outer edge and the top cover portion 4 rests just inside the bottom base portion 6. The top cover portion 4 and bottom base portion 6 have corresponding rectangular sections removed on their left and right sides to define a rectangular opening 21 to receive the swing bar of a semi-trailer door (not shown).
The bottom base portion 6 has an upper plate 26 (the first plate) and a lower plate 29 (the second plate) defining a central raised housing portion 22.
The left arm 46 and right arm 48 of the lower plate 29 are shown extending through the top cover portion 4. A channel 10 is defined through which a high security lock 54 (not shown) may be inserted. The top cover portion 4 has a protrudement 14 between the left arm 46 and right arm 48 which serves to prevent common tools such as bolt cutters or hacksaws from being used to remove the high security lock.
Referring to Figure 2, the locking device 2 is shown in the open unlocked position.
The top cover portion 4 is connected to the bottom base portion 6 by means of a hinge 8 through which an attachment pin 18 (see Fig. 6A) passes. The attachment pin 18 does not extend through the right side of the top cover portion 4 so that thieves can not hammer it out with a punch. The shape of the attachment pin 18 on the left side of the top cover portion 4 is angled, not only to contour to the shape of the top cover portion 4, but to prevent drilling from thieves. When the attachment pin 18 is fully inserted into the top cover portion 4 and bottom base portion 6, two locking split pins 20 secure the attachment pin 18.
This prevents the attachment pin 18 from outward movement. The Teflon bushing prevents the attachment pin 18 from seizing.
Referring to Figure 1, there is shown a locking device 2 comprising a top cover portion 4 and a bottom base portion 6 in closed unlocked position. The top cover portion 4 and the bottom base portion 6 are hingedly connected along their top edges by a hinge 8. The bottom edge of the top cover portion 4 is shaped to form a handle 7.
The bottom base portion 6 has a small raised ridge 24 completely along its outer edge and the top cover portion 4 rests just inside the bottom base portion 6. The top cover portion 4 and bottom base portion 6 have corresponding rectangular sections removed on their left and right sides to define a rectangular opening 21 to receive the swing bar of a semi-trailer door (not shown).
The bottom base portion 6 has an upper plate 26 (the first plate) and a lower plate 29 (the second plate) defining a central raised housing portion 22.
The left arm 46 and right arm 48 of the lower plate 29 are shown extending through the top cover portion 4. A channel 10 is defined through which a high security lock 54 (not shown) may be inserted. The top cover portion 4 has a protrudement 14 between the left arm 46 and right arm 48 which serves to prevent common tools such as bolt cutters or hacksaws from being used to remove the high security lock.
Referring to Figure 2, the locking device 2 is shown in the open unlocked position.
The top cover portion 4 is connected to the bottom base portion 6 by means of a hinge 8 through which an attachment pin 18 (see Fig. 6A) passes. The attachment pin 18 does not extend through the right side of the top cover portion 4 so that thieves can not hammer it out with a punch. The shape of the attachment pin 18 on the left side of the top cover portion 4 is angled, not only to contour to the shape of the top cover portion 4, but to prevent drilling from thieves. When the attachment pin 18 is fully inserted into the top cover portion 4 and bottom base portion 6, two locking split pins 20 secure the attachment pin 18.
This prevents the attachment pin 18 from outward movement. The Teflon bushing prevents the attachment pin 18 from seizing.
4 The top cover portion 4 is kept open relative to the bottom base portion 6 by means of a safety clip 16. The safety clip 16 is attached to the top cover portion 4 by a small split pin (not shown). This safety clip 16 falls into a cavity 19 formed by the hinge 8 of the bottom base portion 6 to keep the top cover portion 4 in the upright position for easy access to the bottom base portion 6.
The bottom base portion 6 has an upper plate 26 and a lower plate 29 defining a central raised housing portion 22.
The upper plate 26 is generally 1-shaped and is attached to the bottom base portion 6 and the door of the semi-trailer by means of a bolt 28 and washer 30. The upper plate 26 can move freely in a left and right and up and down position relative to the bottom base portion 6. The end 32 of the upper plate is formed into a c-shape to engage one end 38 of the lower plate 29.
The lower plate 29 is attached to the bottom plate cover portion 6 and the door of the semi-trailer (not shown) by means of a bolt 34. An additional bolt 36 is used to attach the lower plate to the bottom plate cover portion 6.
The bottom base portion 6 has a small raised ridge 24 completely along its outer edge such that, when in top cover portion 4 and bottom base portion 6 are in the closed position, the top cover portion 4 rests just inside the bottom base portion 6. This makes the locking device highly resistant to thieves attempting to open the locking device using a crow bar.
One end 38 of the lower plate 29 is shaped to engage the c-shaped end 32 of the upper plate.
The one end 38 has a hole 40 and the c-shaped end 32 has a hole 42 which line up to receive a freight seal 44 which passes therethrough and is locked in place.
The lower plate 29 has a left arm 46 and a right arm 48. The left arm 46 and right arm 48 are positioned to pass through corresponding openings in the top cover portion 4.
