DETAILED DESCRIPTION OF THE INVENTION

(12) FIG. 1 shows the rear of a vehicle such as a trailer having a cargo compartment accessible through two side mounted swing-out type access doors 10 and 12. Each door has a rotatably mounted handle 14 which controls the latching and unlatching of the door. Each handle is connected to a vertically moveable rod 16 by a pivot bracket 18. The unattached end of the handle can be moved about the vertical axis of the associated rod between a position in which the handle end is adjacent a plate 20 mounted on the surface of the door, and a position remote from the surface of the door. In the latter position, the handle can be pivoted about the axis of the pivot pin 22 of bracket 18 such that rod 16 can be moved relative to the door jamb to latch and unlatch the door.

(13) FIG. 2 shows the handle and seal mounting hardware in greater detail. In particular, it shows that the handle of the right hand door has a metal bolt type seal 24 mounted on it. FIG. 3 shows the mounting hardware and seal in still greater detail.

(14) As seen in FIG. 3, the seal mounting hardware includes plate 20 fixed to the surface of the door by screws or other fasteners (not shown) in openings 30. A part 26 extends outwardly from the surface of the lower portion of plate 20. Part 26 has an opening.

(15) A part 28 is rotationally connected to the surface of the upper portion of plate 20. Part 28 can rotate about the axis of a pin (not shown) situated in an opening 29. Part 28 carries a protruding member 32. Part 28 can be moved to move member 32 between a position out of alignment with part 26 and a position in alignment with part 26. Member 32 also has an opening therein.

(16) This configuration allows part 28 to be rotated to a position out of alignment with part 20 such that handle 14 can be moved to a position adjacent the surface of part 20. Part 28 can then be rotated to a position, shown in FIG. 6, over the upper portion of plate 20, where part 32 is adjacent to part 26 and handle 14 is encircled by members 20 and 28. To facilitate such rotation, part 32 is arcuate, as shown.

(17) In that position, the neck of the seal, in this case a metal bolt type seal 24, can be threaded through the aligned openings in parts 26 and 32 and secured by affixing an end stop 25 on the free end of the seal neck. Once the seal is mounted on the door hardware, the handle cannot be moved from its position without breaking the seal.

(18) As seen in FIG. 3, when a metal bolt type seal 24 is used on a handle with a bend, the handle may be provided with a reinforcing member 34 which extends along the axis of the handle and bridges the bend in the handle. Member 34 will be provided with an opening which aligns with the openings in parts 26 and 32 such that the neck of the seal can pass through member 34.

(19) FIGS. 4 and 5 show the handle and mounting hardware as it would appear with a plastic seal 36. In this case, plastic seal 36 takes the form of a conventional cable tie.

(20) FIGS. 6 and 7 show the first preferred embodiment of the seal protector of the present invention which is designed to guard the integrity of a plastic or metal bolt seal mounted on the side mounted swing-out type door of the cargo compartment of a vehicle. As seen in these figures, the seal protector is a strong metal housing, generally designated A, formed of two hollow housing parts which when closed fully enclose the seal 24 and the portion of the door handle 14 where the seal 24 is situated.

(21) Seal protector A is designed to be removeably mounted on the vehicle door before or after the seal 24 is installed. A padlock 38 with a shackle 40 or the like may be used to lock the housing parts in the closed position. At the destination point, the housing is unlocked and the seal may be examined to determine if the seal is broken.

(22) The housing parts include a base part 42 and a cover part 44. The housing parts are connected by a strong spring-loaded hinge 46 which is covered and protected from attack. The hinge allows the housing parts to move between an open position as seen in FIG. 6, in which the seal is exposed, and a closed position as seen in FIG. 7, in which the seal cannot be accessed.

(23) The spring in the hinge urges the housing parts toward the open position. Accordingly, when the housing is removed from the door the housing parts will automatically open to expose the seal so it can easily be examined.

(24) At least one of the housing parts, in this case cover part 44, includes opposite side walls 48, 50 having aligned recesses 52, 54. The recesses are designed to accommodate the handle such that when the housing parts are in the closed position, the seal is fully enclosed.

(25) Base part 42 is generally planar and is formed with an open ended recess 58 such that it can accommodate the plate 20. This structure allows protector A to be mounted on and removed from the vehicle door surface when the housing parts are in the open position.

(26) A member 60 with an opening 62 is connected to the unattached edge of base part 42 (the edge which is remote from hinge 46) by a strong protected hinge 64. Thus, member 60 can rotate relative to base part 42. Member 60 has an opening 62.

(27) A member 66 is fixedly attached to the cover part 44. Member 66 has an opening 68. When the housing parts are in the closed position, as seen in FIG. 7, members 60 and 66 are adjacent to each other and the openings 62 and 68 in those members are aligned. In that position, the shackle 40 of a padlock 38 can be received through aligned openings 62 and 68, locking the housing parts in the closed position.

(28) In this preferred embodiment, the sides of housing A are parallel to each other. Thus, the housing parts, when in the closed position, form a box-like enclosure.

(29) A second preferred embodiment of the present invention, as seen in FIGS. 8 and 9, is also designed from use on a side mounted swing-type door. The second preferred embodiment includes a housing, generally designated B, which functions in a manner similar housing A of the first preferred embodiment but is designed to be permanently fixed to the door surface.

(30) In this embodiment, the open ended recess of base part 42 is replaced with an oval cut-out 59 sized and shaped to accommodate the seal mounting plate 20. The base part 42 is situated adjacent the surface of the vehicle door, completely surrounding plate 20 of the seal mounting hardware.

(31) In this second preferred embodiment, the shape of the cover part 44 is that of an elongated, truncated pyramid. The cover part has with outwardly inclined sides 70, 72, 74 and 76. Sides 70 and 74 are oppositely inclined. Sides 72 and 76 are oppositely inclined. Recesses 52 and 54 are provided in the cover part to accommodate the handle.

(32) The lower right hand corner of cover part 44 has a recess 78 with a flat section 80 having an elongated opening 82. The lower right hand section of base part 42 has a loop member 84 mounted thereon. When cover part 44 is closed over base part 42, loop member 84 extends through opening 82 in the cover part such that the shackle 40 of a padlock 38 can be received therein to lock the housing parts in the closed position.

(33) FIG. 10 illustrates a third preferred embodiment of the present invention which is designed for use with roll-up type cargo doors. Roll-up cargo doors have a rotatable handle 14 which causes a J hook type latch (not shown) to engage a part in the door jamb to prevent the door from being opened.

(34) The door also has rotatable locking member 86 which rotates about the axis of a pin 88. The axis of pin 88 is perpendicular to the surface of the vehicle door and is parallel to the axis about the pin adapted to be received in opening 22 about which the handle 14 rotates.

(35) Member 86 has a tail 90 with an opening 92 which aligns with the opening 96 in end 98 of handle 14 when the handle is in the closed position, as seen in the FIG. 10. When the handle and locking member are in the position illustrated in FIG. 10, the seal 24 can be threaded through aligned openings 92 and 96. Rotation of handle 14 from that position will break seal 24, indicating that the door may have been opened.

(36) The third preferred embodiment is similar in structure to the first preferred embodiment in that the housing, generally designated C, has a rectangular shaped cover part 44 which is connected to a generally planar base part 42 by a hinge 46. Thus, when the cover part is in the closed position, the opening 68 in member 60 aligns with the opening 100 in member 66 and the shackle of a padlock can be inserted through the aligned openings to lock the housing parts in the closed position.

(37) The main difference is that, in the third preferred embodiment, housing C is elongated in the lateral direction to accommodate the horizontally extending seal 24. However, the function of the third preferred embodiment of the protector is essentially the same as that of the first and second preferred embodiments.

(38) While only a limited number of preferred embodiments of the present invention have been disclosed for purposes of illustration, it is obvious that many modifications and variations could be made thereto. It is intended to cover all of those modifications and variations which fall within the scope of the present invention, as defined by the following claims.
