DETAILED DESCRIPTION

The present disclosure describes a device to secure a hinge located on a door panel. The device clamps on to the hinge and when secured, prevents the hinge from turning due to a counter force that is applied against the hinge. This secures the door panel attached to the hinge and prevents the door panel from being opened when the device is engaged over the clamp. The lock that is used to secure the device is hidden from view, and generally more difficult to access, thereby making it difficult and time consuming for someone to try and cut the lock and disengage the device from the hinge.

In various embodiments, the present disclosure describes a hinge grip assembly to secure the hinge located on a door panel of a shipping container. Each device, as described by various embodiments of the present disclosure, may be attached to a single hinge of a door of a container. Since a container usually has two doors along the width of the container, two such devices may be used to secure both the doors. When used to secure the door panels of a shipping container, it prevents the doors from being opened when the device is engaged over at least one hinge of each door panel. Therefore, when the container is in transit, those that may try to break-in to the container may not be successful, as they will have to break the normal locks on the container, and additionally they will have to disengage the hinge grip assembly over each hinge. Disengaging the hinge grip assembly over each hinge posses an additional obstacle that may delay those trying to gain access and risk being caught in the process. Further, it may be impossible to disengage the hinge grip assembly due to its construction. For example, the hinge grip assembly may be engaged by a member and access to the member may be prevented by physically limiting access through a lock or another mechanism. The lock itself may be difficult to break due to its construction. Therefore, the hinge grip assembly provides an improvement in the field of container transportation and security by securing the hinge attached to the door and thereby preventing the door to be opened by unauthorized people.

In the following paragraphs, the embodiments are described in further detail by way of example with reference to the attached drawings. In the description, well known components, methods, and/or processing techniques are omitted or briefly described so as not to obscure the embodiments. As used herein, the “present invention” refers to any one of the embodiments of the invention described herein and any equivalents. Furthermore, reference to various feature(s) of the “present invention” is not to suggest that all embodiments must include the referenced feature(s).

The embodiments described herein are not limited in application to the details set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or carried out in various ways. Also, the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including,” “comprising,” or “having” and variations thereof herein is meant to encompass the items listed thereafter, additional items, and equivalents thereof. The terms “connected” and “coupled” are used broadly and encompass both direct and indirect connections and couplings. In addition, the terms “connected” and “coupled” are not limited to electrical, physical, or mechanical connections or couplings.

Turning now to the drawings, exemplary embodiments are described in detail. FIG. 1 shows a three-dimensional view of a hinge attached to a door panel of a shipping container. As seen in FIG. 1, container 102 includes hinge 104 that is attached to door panel 106. Also shown in FIG. 1, is frame 108 to which hinge 104 is attached. Frame 108 has a hollow area and a lip that forms a U or J profile. Hidden from view in FIG. 1 is a gap between hinge 104 and frame 108 when viewed from a side angle.

FIG. 2 shows a three-dimensional view of a hinge grip assembly attached to the hinge of a shipping container, in accordance with various embodiments of the present disclosure. As seen in FIG. 2, container 102 is shown with hinge grip assembly 202 attached to hinge 104 (not shown), Hinge grip assembly 202 may be secured to hinge 104 using lock 204. Lock 204 may prevent hinge grip assembly 202 to be disengaged. For hinge grip assembly 202 to be disengaged, or taken apart, lock 204 may need to be unlocked and removed from hinge grip assembly 202. Since lock 204 sits flush within hinge grip assembly 202 and does not expose any shackle or shank that would have been exposed, it is much difficult to quickly tamper with lock 204 and disengage hinge grip assembly 202. This is not the case where padlocks may be used to secure the traditional locking mechanism in the container door.

FIGS. 3A and 3B show three-dimensional views of a hinge grip assembly, in accordance with various embodiments of the present disclosure, As seen in FIGS. 3, hinge grip assembly 202 may include clamp 302 and body 304. Clamp 302 may be an L shaped piece or assembly. In various embodiments, clamp 302 may be a single part that may be die cast or may be pressed into shape. It may be right angular with a side portion and a top portion. In various embodiments, claim 302 may be welded or joined together using methods that will be apparent to those skilled in the art.

Body 304 may include lock ring 306. Clamp 302 may include nut 310 that may be attached to clamp 302. Nut 310 may engage with bolt 308 that may be inserted via an opening in body 304 at an end where lock ring 306 is located, or a front end. Clamp 302 may also include lip 326. Lip 326 may be a protrusion or extension that is angled and extends out of a surface, such as a side portion of clamp 302.

Body 304 may include top portion 318 and two side panels 323 and 325, with an opening at a bottom part. In various embodiments, the front end of body 304 may be attached to lock ring 306. In various embodiments, the front end of body 304 and lock ring 306 may be die cast as a single piece. A back end opposite to the front end may be open. Top portion 318, side panels 323 and 325, and the front end may form an open rectangular shape.

FIG. 4 shows a three-dimensional view of a hinge grip assembly, in accordance with various embodiments of the present disclosure. As seen in FIG. 4, hinge grip assembly 202 is disengaged. Also shown in FIG. 4 is opening 312 in body 304. Body 304 may also include wings 314. Wings 314 may be located on the top portion of body 304 with a recess or opening in between the two wings. The top portion of body 304 and the two side panels may form an opening 316.

When body 304 is engaged with clamp 302, a portion of the top portion of body 304, such as wings 314, may slide under a top portion 318 of clamp 302. Side portion 320 of clamp 302 is perpendicular to top portion 318. Opening 316 may engage with a lip that may exist in frame 108 of container 102, around hinge 104 (as seen in FIG. 1). Nut 310 may be attached to plate 322 which may be attached to damp 302. Plate 322 may slide under the top portion of body 304 when hinge grip assembly 202 is engaged by fully tightening bolt 308 with nut 310. Hinge grip assembly 202 may be engaged by inserting bolt 308 into opening 312 from the front end. Bolt 308 may engage with nut 310 to tighten damp 302 with body 304 over hinge 104. When hinge grip assembly 202 is engaged, a portion of body 304, such as the bottom portion (or more specifically, the bottom exposed surface of the two side panels and the front end) may be contact with door panel 106. Further, side portion 320 of damp 302 may be in contact with a side portion of frame 108. Additionally, lip 326 may be designed with dimensions such that it can be partially or fully inserted into gap 110.

If door panel 106 is being opened when hinge grip assembly 202 is engaged, an outward radial force may be applied in a direction of the ZZ axes (as shown in FIG. 4) perpendicular to plane formed by the XX and YY axes (as shown in FIGS. 3 and 4), due to door panel 106 being in contact with body 304. Wings 314, which are in contact with top portion 318 of damp 302 prevent movement of body 304, which in turn prevents movement of door panel 106. Further, wings 314 dose any gap between clamp 302 and body 304. This prevents anyone trying to use a prybar or similar device to pry a gap between damp 302 and body 304. Since side portion 320 is pressed against outer portion of frame 108, it prevents damp 302 from moving in the direction of the force (as is caused side portion 320 to further press into the outer portion of frame 108). Therefore, hinge grip assembly 202 functions to keep door frame from moving outward when engaged. Since hinge grip assembly 202 is engaged by bolt 308, access to bolt 308 may be prevented by placing lock 204 into lock ring 306.

FIG. 5 shows a view of body viewed from the lock ring end of a hinge grip assembly, in accordance with various embodiments. Also seen in FIG. 5 is opening 312 in body 304 into which bolt 308 may be inserted, Access to bolt 308 may be prevented by attaching a lock, such as lock 204 (seen in FIG. 2). In various embodiments, lock 204 may be a puck lock. The puck lock may have an engaging cylinder that may clamp over hole 324 to ensure that puck lock is locked and engaged.

In various embodiments, nut 310 may be welded to plate 322 which may be welded to clamp 302, In various embodiments, nut 310 may be integrated with plate 322 during the manufacturing process, such as being cast as a single component, etc. In various embodiments, plate 322 may be integrated with clamp 302 during the manufacturing process.

FIGS. 6A and 6B show two views of clamp in accordance with various embodiments of the present disclosure. Clamp 302 is shown with top portion 318 and side portion 320. Plate 322 is attached to top portion 318 by connector 602. Connector 602 may be attached to top portion 318 by a weld or may be integral to top portion 318 (single cast piece), Plate 322 may be attached to connector 602 by a weld or may be integral to top portion 318 (single cast piece). Plate 322 may contain two counter-sunk holes 604, Tension block 606 is also shown in FIGS. 6A and 6B, adjacent to plate 322. Tension block 606 may be attached to plate 322 by two fasteners that are inserted through two openings 608a and 608b in tension block 606 that align with holes 604. A third opening 610 in tension block 606 (perpendicular for the two openings that align with holes 604) may receive bolt 308. This opening 610 may be threaded such that bolt 308 may directly engage with it,

FIGS. 7A and 7B shows two views of a tension block in accordance with various embodiments of the present disclosure. Tension block 606 includes two openings 608a and 608b that align with the two counter-sunk holes 604 of plate 322 (as shown in FIGS. 6A and 6B). The diameter of holes 608 may match the smaller diameter of the counter-sunk holes 604. A fastener may be inserted through opening 610 to secure tension block 606 (and thus clamp 302) to body 304. Opening 610 may be threaded, allowing bolt 308 to be attached to tension block 606. Using a removably attached tension block 606, allows it to be replaceable in case of wear and tear of threads in opening 610. Alternatively, opening 610 may not be threaded and a nut may be attached to bolt 308 that extends beyond tension block 606.

In various embodiments, hinge grip assembly 202 is made from a stainless-steel plate, In various embodiments, the thickness of the stainless-steel plate is selected to withstand heat and/or physical force. In various embodiments, hinge grip assembly 202 is made from composite material, a metal, a metal alloy, or a combination of one or more of the above.

In various embodiments, a different locking mechanism may be used to secure access to bolt 308 at the front end. For example, bolt 308 may have a hole at its head that may align with hole 324 and a lock may be used to secure bolt 308 to hole 324.

In various embodiments, bolt 308 may be welded to opening 312. To disengage hinge grip assembly 202, special apparatus may be needed to remove the weld.

In various embodiments, a hinge grip assembly, in accordance with various embodiments described herein, may be attached to one hinge of each of the two door panels on a shipping container. To attach a hinge grip assembly to a hinge, such as hinge 104, clamp 302 may be placed on the outside of container 102, such that side portion 320 covers the side of the hinge and top portion 318 covers the front of the hinge. Next, body 304 is slid into place such that opening in the body, such as opening 316, mates with the frame of the container and the wings slide under the top portion
