Shielded Lock Hasp for Vehicle Door

Abstract

Locking hasp brackets for a vehicle door are secured to the vehicle by the fasteners that secure the latch and strike for the door and extend through the crack at the edge of the door when the door is shut to a tab that projects beyond the outer side of the vehicle. A base wall is fixed to the tab in a lateral plane that is parallel to the axes of the fastener holes for the fasteners that secure the brackets and closely adjacent to the outside of the vehicle, and side walls extend from the periphery of the base wall so as to at least partially enclose the sides of the tab and create a protected space within which a puck lock or padlock resides that secures the tabs of the two brackets to one another.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0029] FIGS. 1-6 depict a pair of brackets 10 and 110 that employ the present invention. FIGS. 1-3 show one of the brackets, 10, and FIGS. 4-6 show the other bracket 110. The bracket 10 shown in FIGS. 1-3 is very similar to the bracket 110 shown in FIGS. 4-6. Only bracket 10 will be described in detail and the differences of bracket 110 from 10 will also be described. The elements of bracket 110 will be described with the same reference numbers as used with respect to bracket 10 plus 100.

[0030] Bracket 10 has a dogleg-shaped portion 12 that is stamped from a piece of stainless steel plate. The dogleg-shaped portion 12 includes longitudinal portion 14, lateral portion 16, and hasp portion 18, which extends longitudinally and includes tab 19 that extends beyond the side of the vehicle 200 and beyond a laterally extending base plate 30. Tab 19 is generally T-shaped and has reinforcement ears 21 bent out laterally at its end, adjacent to where hole 24 with lateral axis 25 resides. Attachment portion 14 has bolt holes 20 each having an axis 23 that extends laterally, generally parallel to the plane of the base plate 30, so that the bracket 10 can be secured to the edge of the door 202 (FIG. 9) or door jamb on the handle side of the door using the fasteners that attach the strike 204. The portion 12 may go between the strike plate and the sheet metal edge of the door or the edge of the door jamb of the vehicle frame. In the bracket 110, the holes 120 are adapted to be secured by the fasteners to the other door 206 (FIG. 10) that secure the latch 208 that latches onto the strike 204, and therefore, the portion 114 has a U-shaped space 127 that creates a pocket in which the opening to the latch resides when the bracket is installed. Usually the brackets extend toward the outside of the door from their mounting to the door to extend beyond an outside surface of the door, but could extend to the inside of the vehicle so as to extend beyond an inside surface of the door, where the lock would be applied to them. The dogleg portions 12 and 112 thus far described are similar to the brackets described in U.S. Pat. No. 8,496,276, the disclosure of which is hereby incorporated by reference for all purposes including showing how the dogleg portions of the brackets are attached to the vehicle.

[0031] When the door or doors are shut the two hasp portions 18 and 118 come together in close side-by-side relationship to one another (FIGS. 11 and 12) so that a padlock or puck lock 209 (FIG. 12) can be put through the holes 24 and 124 to attach the two hasp portions to one another. The invention herein modifies the dogleg section to include a base wall 30 extending from the hasp portion 18 so as to be parallel to the vehicle body (outer side of the door or outer side of the jamb) and in very close relationship to the vehicle body. The base wall 30 may in fact be abutting the exterior surface of the vehicle body so that it makes it extremely difficult to slip a saw blade between the base wall 30 and the side surface 32 or 132 of the respective vehicle door 202 or 206, but if a blade does get behind the wall 30 the thief will have to cut through the entire length of stainless steel bracket 14 shown in FIG. 2 (or 114 in FIG. 5) instead of being able to cut through just the smaller bracket 19 (FIGS. 1 and 2, or 119 in FIGS. 4 and 5), which extends much less in height than bracket 14, 114 in the hasp portion 18, 118 just behind the wall 30, 130.

[0032] The base wall 30 may be a flat circular segment as illustrated in FIGS. 1 and 4 and have two side walls 36, 38 in the case of the bracket 10, or one side wall 136 in the case of the bracket 110, affixed at the periphery of the base wall 30 or 130 respectively. In the bracket 10, there are two side walls 36 and 38 with a space 39 between them so as to provide access to the key hole of a puck lock through the space 39 but no such space is necessary on the other bracket 110 and so it has a single side wall 136 that goes around essentially the entire periphery of the base plate 130. The side walls may be secured to the base plate and to the hasp portion 18 by welding and the base plate 30 may be attached to the hasp portion 18 by welding. Preferably, the entire bracket is made of stainless steel because stainless steel is very difficult to cut and resistant to hammering and prying.

[0033] The base plate and side plate or plates provide a space in which the projecting tab portions 19, 119 of the hasp portions 18, 118 reside to protect the tabs and the padlock or puck lock contained within the space against cutting, prying, hammering, and other tampering and abuse.

[0034] The invention provides an extreme impact in a sense of overall security. It provides a major increase in area that is required to be cut by a potential thief. The original 1 tab remains, however there is an addition of nearly two times the material that must be cut through to get beyond that half of the shell. Overall the invention adds about four inches (two inches on each bracket) of material (stainless steel in the preferred embodiment) that needs to be cut before the lock will be rendered useless. Beyond offering superior protection against being cut off, the 1 outer shell provided by the sidewalls provides a better barrier against prying and impacts from a sledgehammer. By making the shield stainless steel, there is an inherent gain in strength and longevity versus other materials that could have been used. Another feature is the ease with which existing brackets for other makes and models of vehicles can be modified to incorporate the invention.

[0035] A preferred embodiment of the invention has been described in considerable detail. Many modifications and variations to the preferred embodiment described will be apparent to a person of ordinary skill in the art. Therefore, the invention should not be limited to the embodiment described.
