BACKGROUND
Technical Field

Exemplary embodiment(s) of the present disclosure relate to hasp locks and, more particularly, to a door hasp lock containing a feature for storing a locking member when the door hasp lock is at an unlocked state.


Prior Art

The use of locks on the outside of trailer doors is known and typical. Regardless of the type of trailer from the smallest to large tractor trailers, the method of securing the trailer is basically the same and needs to be improved. The disadvantage of the outside-style lock is that it is easy for thieves to break by cutting the lock or lock hasps. To limit access to a trailer's contents, owners of trailers will commonly back up heavy equipment against the trailer door when they leave the trailer. Tractor trailers occasionally will be backed up to a wall when left overnight. Owners of trailers try the methods described above because of the lack of effective security systems.


When the trailer is detached from the vehicle, the locking member must be either carried by the user or stored in a designated location. Such requirements are inconvenient and may lead to stolen locking members. U.S. Pat. No. 7,562,546 tried to solve this problem but requires a specific hook-shaped securing member that is attached to the door hasp lock. The use of the specific hook-shaped securing member limits the ability to interchangeably use a variety of conventional locks with the door hasp lock.


Alternate conventional door hasp locks require the user to secure the lock on the main locking protrusion of the door hasp lock. This inhibits full functioning of the door because the user must remove the locking member and close the doors while holding the locking member.


Accordingly, a need remains for door hasp lock in order to overcome at least one aforementioned shortcoming. The exemplary embodiment(s) satisfy such a need by providing a door hasp lock that is convenient and easy to use, lightweight yet durable in design, versatile in its applications, and designed for storing a locking member when the door hasp lock is at an unlocked state.


BRIEF SUMMARY OF NON-LIMITING EXEMPLARY EMBODIMENT(S) OF THE PRESENT DISCLOSURE

In view of the foregoing background, it is therefore an object of the non-limiting exemplary embodiment(s) to provide a door hasp lock containing a feature for storing a locking member when the door hasp lock is at an unlocked state. These and other objects, features, and advantages of the non-limiting exemplary embodiment(s) are provided by a door hasp lock for use with a trailer. Such a door hasp lock includes a first lock plate having a first planar anterior surface, a first flange statically coupled to the first planar anterior surface, and a first shield statically coupled to the first planar anterior surface. A second lock plate is detachably engaged with the first lock plate and has a second planar anterior surface, a second flange statically coupled to the second planar anterior surface and being detachably engaged with the first flange, a third flange statically coupled to the second planar anterior surface, and a second shield statically coupled to the second planar anterior surface.

Advantageously, the locking member is configured to removably pass through the third aperture when the door hasp lock is disposed at the non-operating unlocked state.


In a non-limiting exemplary embodiment, the locking member includes a rigid cover having a plurality of slots, a locking cylinder operably engaged with selective ones of the slots, a locking implement slidably positioned within the locking cylinder and operably engaged with alternate ones of the slots, and a key operably engaged with the locking implement for slidably reciprocating the locking cylinder between locked and unlocked positions. Advantageously, the locking cylinder is selectively locked to the first flange and the second flange, when the door hasp lock is disposed at the operating locked state. Advantageously, the locking cylinder is selectively locked to the third flange when the door hasp lock is disposed at the non-operating unlocked state.


The present disclosure further includes a method of utilizing a door hasp lock with a trailer. Such a method includes the steps of: providing a first lock plate having a first planar anterior surface, a first flange statically coupled to the first planar anterior surface, and a first shield statically coupled to the first planar anterior surface; providing and detachably engaging a second lock plate with the first lock plate, wherein the second lock plate has a second planar anterior surface, a second flange statically coupled to the second planar anterior surface and detachably engaged with the first flange, a third flange statically coupled to the second planar anterior surface, and a second shield statically coupled to the second planar anterior surface.


The method further includes the step of: disposing the door hasp lock at an operating locked state and a non-operating unlocked state by engaging and disengaging the first lock plate and the second lock plate, respectively. Each of the first shield and the second shield has an arcuate shape. The third flange has at least one feature that permits the third flange to break away from the second lock plate when tampered by an unauthorized user. The third flange is spaced apart from the first flange and the second flange while the door hasp lock is disposed at both the operating locked state as well as the non-operating unlocked state.

The non-limiting exemplary embodiment(s) is/are referred to generally in FIGS. 1-25 and is/are intended to provide a door hasp lock 10 containing a feature for storing a locking member 30 when the door hasp lock 10 is at an unlocked state. The door hasp lock 10 may be used with a trailer or the like. Advantageously, the door hasp lock 10 includes a third flange 18 for temporary storage of the locking member 30 (e.g., hidden shackle lock, pad lock, combination lock, etc.) while not in use. It is noted that a variety of locks may be used. The configuration of the third flange 18 may be similar to the first flange 13 and the second flange 17, therefore it does not introduce any restrictions and allows for the use of a variety of locking device. Advantageously, the third flange 18 can be used to secure the locking member 30 while not in use (e.g., the doors are open and you need a place to store the locking member 30). The third flange 18 will break off before enough force is applied to overcome the method of attachment of the second lock plate 15 to the trailer/door/wall.


Referring again to FIGS. 1-25, the door hasp lock 10 includes a first lock plate 11 having a first planar anterior surface 12, a first flange 13 statically coupled to the first planar anterior surface 12, and a first shield 14 statically coupled (e.g., welded) to the first planar anterior surface 12. A second lock plate 15 is detachably engaged with the first lock plate 11 and has a second planar anterior surface 16, a second flange 17 statically coupled to the second planar anterior surface 16 and detachably engaged with the first flange 13, a third flange 18 statically coupled to the second planar anterior surface 16, and a second shield 19 statically coupled (e.g., welded) to the second planar anterior surface 16. Such a structural configuration provides the new, useful, and unexpected result of enabling a user to temporarily store a locking member 30 at the second lock plate 15 (via the third flange 18) when the trailer doors are open, for example, while protecting the locking member 30 from unauthorized access (e.g., prying away the locking member from the first flange 13 and second flange 17). Notably, the third flange 18 has break away portions 22 that prevent a thief from using the third flange 18 as a leverage point to remove the second lock plate 15 from the trailer. The third flange 18 will break off before enough force is applied to overcome the method of attachment of the second lock plate 15 to the trailer/door/wall. It is noted the third flange 18 may be attached to either the first lock plate 11 or second lock plate 15.


Advantageously, the first flange 13 and second flange 17 are directly engaged (abutted) when the first lock plate 11 and the second lock plate 15 are engaged and disengaged (e.g., disposed at an operating locked state 20 and a non-operating unlocked state 21), respectively. Advantageously, the third flange 18 is spaced apart from the first flange 13 and the second flange 17 while the door hasp lock 10 is disposed at both the operating locked state 20 as well as the non-operating unlocked state 21. Advantageously, the third flange 18 has at least one feature that permits the third flange 18 to break away from the second lock plate 15 when tampered by an unauthorized user. Such a feature may include one or more portions of weakness 22 (e.g., bend, shoulder) having a reduced cross-sectional thickness, for example. Such a structural configuration provides the new, useful, and unexpected result of preventing a thief from using the third flange 18 as a leverage point to remove the second lock plate 15 from the trailer. The third flange 18 will break off before enough force is applied to overcome the method of attachment of the second lock plate 15 to the trailer/door/wall. In other words, the third flange 18 will break off and the second lock plate 15 will remain at the trailer, thereby rendering the door hasp lock 10 useless. As noted above, the third flange 18 may be attached to either the first lock plate 11 or second lock plate 15.


Each of the first lock plate 11 and second lock plate 15 having holes 23 for receiving fasteners therethrough when being secured to a trailer's doors, for example.


In a non-limiting exemplary embodiment, each of the first shield 14 and the second shield 19 may have an arcuate shape.


In a non-limiting exemplary embodiment, the door hasp lock 10 further includes a locking member 30 is removably affixed to the first flange 13 and the second flange 17 when the door hasp lock 10 is disposed at the operating locked state 20. Such a locking member 30 is situated between the first shield 14 and the second shield 19, and thereby protected from unauthorized tampering (e.g., using a crowbar to pry off the locking member 30 from the first flange 13 and second flange 17).


In a non-limiting exemplary embodiment, the locking member 30 is detached from both of the first flange 13 and the second flange 17, as well as attached to the third flange 18, when the door hasp lock 10 is disposed at the non-operating locked state 21. Advantageously, the locking member 30 is situated exterior of the first shield 14 and the second shield 19. Such a structural configuration provides the new, useful, and unexpected result of enabling a user to temporarily store locking member 30 at the second lock plate 15 when the trailer doors are open, for example. As noted above, such a structural configuration further provides the new, useful, and unexpected result of preventing a thief from using the third flange 18 as a leverage point to remove the second lock plate 15 from the trailer. The third flange 18 will break off before enough force is applied to overcome the method of attachment of the second lock plate 15 to the trailer/door/wall. In other words, the third flange 18 will break off and the second lock plate 15 will remain at the trailer, thereby rendering the door hasp lock 10 useless. As noted above, the third flange 18 may be attached to either the first lock plate 11 or second lock plate 15.


In a non-limiting exemplary embodiment, a third shield 28 is statically coupled to the first planar anterior surface 12 of the first lock plate 11 and spaced apart from the first shield 14 and the second shield 19. Such a structural configuration provides the new, useful, and unexpected result of intercalating locking member 30 between the first shield 14, the second shield 19, and the third shield 28 thereby protecting locking member 30 from unauthorized tampering (e.g., using a crowbar to pry off the locking member 30 from the first flange 13 and second flange 17).


In a non-limiting exemplary embodiment, the first shield 14 and the second shield 19 are configured in a generally annular pattern 29 about the first flange 13 and the second flange 17. Such an annular pattern 29 substantially conforms to the annular shape of the locking member 30 (e.g., hidden shackle padlock).


In a non-limiting exemplary embodiment, the generally annular pattern 29 is configured to receive the locking member 30 therein. Such a structural configuration provides the new, useful, and unexpected result of shielding the locking member 30 from unauthorized tampering while the trailer doors are closed, for example.


In a non-limiting exemplary embodiment, the first flange 13 has a first aperture 31, the second flange 17 has a second aperture 32, and the third flange 18 has third aperture 33. Advantageously, the locking member 30 is configured to removably pass through the first aperture 31 and the second aperture 32 when the door hasp lock 10 is disposed at the operating locked state 20. Advantageously, the locking member 30 is configured to removably pass through the third aperture 33 when the door hasp lock 10 is disposed at the non-operating unlocked state 21. Such a structural configuration provides the new, useful, and unexpected result of enabling a user to temporarily store a locking member 30 at the second lock plate 15 when the trailer doors are open, for example.


In a non-limiting exemplary embodiment, the locking member 30 includes a rigid cover 34 having a plurality of slots 35 (35a, 35b, 35e, 35f), a locking cylinder 36 operably engaged with selective ones of the slots 35e, 35f, a locking implement 37 slidably positioned within the locking cylinder 36 and having additional slots 35c, 35d. The locking implement 37 having a resilient finger 44 operably engaged with alternate ones of the slots 35b, 35d (e.g., 35b may be either diametrically opposed circular slots or a curvilinear slot 35b shown in FIG. 25), and a key 38 operably engaged with the locking implement 37 for slidably reciprocating the locking cylinder 36 between locked and unlocked positions. Advantageously, the locking cylinder 36 is selectively locked (e.g., passed through) to the first flange 13 and the second flange 17, when the door hasp lock 10 is disposed at the operating locked state 20. Advantageously, the locking cylinder 36 is selectively locked (e.g., passed through) to the third flange 18 when the door hasp lock 10 is disposed at the non-operating unlocked state 21. A threaded screw 47 is rotatably anchored to the cover 34 and provides a guide along which the locking cylinder 36 slides via slot 35c. As noted hereinabove, a variety of locking members 30 may be employed. There is no need to specifically employ the hidden shackle padlock described herein.


The present disclosure further includes a method of utilizing a door hasp lock 10 with a trailer. Such a method includes the steps of: providing a first lock plate 11 having a first planar anterior surface 12, a first flange 13 statically coupled to the first planar anterior surface 12, and a first shield 14 statically coupled to the first planar anterior surface 12; providing and detachably engaging a second lock plate 15 with the first lock plate 11 (e.g., directly abutting, engaging, and aligning the first flange 13 to the second flange 17), wherein the second lock plate 15 has a second planar anterior surface 16, a second flange 17 statically coupled to the second planar anterior surface 16 and detachably engaged with the first flange 13, a third flange 18 statically coupled to the second planar anterior surface 16, and a second shield 19 statically coupled to the second planar anterior surface 16.


The method further includes the step of: disposing the door hasp lock 10 at an operating locked state 20 and a non-operating unlocked state 21 by engaging and disengaging the first lock plate 11 (e.g., first flange 13) and the second lock plate 15 (e.g., second flange 17), respectively. Each of the first shield 14 and the second shield 19 has an arcuate shape. The third flange 18 has at least one feature that permits the third flange 18 to break away from the second lock plate 15 when tampered by an unauthorized user. The third flange 18 is spaced apart from the first flange 13 and the second flange 17 while the door hasp lock 10 is disposed at both the operating locked state 20 as well as the non-operating unlocked state 21. Such a structural configuration provides the new, useful, and unexpected result of preventing a thief from using the third flange 18 as a leverage point to remove the second lock plate 15 from the trailer. The third flange 18 will break off before enough force is applied to overcome the method of attachment of the second lock plate 15 to the trailer/door/wall. In other words, the third flange 18 will break off and the second lock plate 15 will remain at the trailer, thereby rendering the door hasp lock 10 useless. As noted above, the third flange 18 may be attached to either the first lock plate 11 or second lock plate 15.
