Security Bracket Apparatus and Method

BACKGROUND OF THE INVENTION

The present invention relates generally to a security apparatus, and more specifically, it relates to a security apparatus for use with various locking devices to aid in securing and preventing unauthorized access to a utility service enclosure, or for example, a watthour meter socket box or other enclosures.

Electrical service providers generally deliver electricity to their customers via power lines buried underground or distributed along poles or towers overhead. The provider's power lines are usually distributed from a power generation station to numerous sets of customer lines, so that customers can then use the power to satisfy their various electrical needs. To measure delivered power so that customers can be billed in proportion to their usage, service providers typically terminate their power lines at a customer's home or business facility through a metered socket box, various designs for which are well known. Natural gas and water service providers deliver and meter services in a similar method.

For example, one previously known electric meter box consists of two sets of electrical posts, with a provider's transmission lines being connected to one set of posts, and the customer's service lines to the other set. In order to measure the amount of electricity a customer uses, the meter box is configured to accept a watt-hour meter or another electricity usage measurement device, which, when plugged into the socket box, permits transmission of electricity from the provider to the customer and allows the amount of transmitted electricity to be accurately measured, so that the provider can charge the customer for power usage at an appropriate rate. The electrical service providers utilize many security apparatus to deter and prevent tampering with the meter. Typically, these security apparatus are locked with a barrel lock. This is largely true also for utility service providers of natural gas and water.

A meter box is generally used by electric utility companies, however the invention herein may be used with other utility service enclosures in the gas, water, cable, TV utility industries or with enclosures generally in various other industries as well.

Various designs and uses for watthour meters are also well known, and all such designs and uses are incorporated into the teachings of the present invention. The present invention is also applicable in situations where the customer's service lines are routed from the meter box to a breaker box so that electricity can be distributed to multiple service locations using additional sets of electrical lines or wires.

Presently, there are two common types of meter socket boxes, each distinguished by the manner in which the meter is secured in place once it has been plugged into an electrical socket disposed in the meter box. For example, a ringed type meter box fitted with a flanged front cover is known, within which a watthour meter is disposed so that a head portion of the meter passes out through a flanged opening in the front cover. In this configuration, the meter is generally held in place using an annular, lockable sealing ring.

Also known is a ringless type meter box, in which the box cover secures the meter in place. For example, a ringless type meter box may include a box cover and a box base. Referring now to prior art FIG. 1, a ringless type meter box 10 includes an installed meter 20 and a box cover 30, the meter box cover being shown prior to installation. Formed around an opening in a central portion of meter box cover 30 is a flange 40; a complementary flange 50 is disposed on meter 20 such that, when meter box cover 30 is installed over and around the head of meter 20, for example, then the meter 20 complementary flange 50 is encased by meter box cover flange 30, and complementary flange sections 40 and 50 join together, so that the meter cannot be easily removed from the electrical socket unless the cover is first removed from the meter box or meter box base.

The meter box cover 30 is typically secured in place by means of a small latch assembly, which functions in structural cooperation with a complementary latch-receiving member disposed on the meter box or base 10. The meter box cover 30 is used to secure the meter 20 to the electrical socket (not shown), so that completion of an electrical circuit is ensured, and the meter is reliably prevented from falling out of the meter box socket.

The meter box cover 30 also prevents unauthorized persons from tampering with the meter. For example, some customers have attempted to bypass the meter, so that unmeasured electricity could be used free of charge. Also, service providers are sometimes forced to disconnect service to customers, for example, due to non-payment of monthly bills. In this event, a locked meter box cover helps prevent a customer from entering the meter box and reconnecting electrical service. However, in instances where the small latch assembly on the meter box fails to provide sufficient security for preventing unauthorized access to the meter and meter box socket, a sturdier, more tamper resistant solution is required.

There are presently only a few commonly used security devices for securing meter box covers to socket boxes. One type requires an installer to drill or punch a hole in the meter box prior to installation of a fastening device. However, some installers are independent contractors rather than employees of the companies that own the meter boxes, and thus drilling or punching a starter hole in the box is sometimes undesirable. Also, drilling takes additional time and adds more steps to the installation, each of which could be avoided if drilling were not required.

To overcome these shortcomings, there are also locks that can be installed on ringless meter socket boxes that do not require drilling or punching a hole in the meter box. Several examples of patents which disclose attempts to solve some of the above problems are set forth as follows.

The Inner-Tite Jiffy Lock™ or “IT Lock,” shown in U.S. Pat. No. 463,245, and U.S. Pat. No. 6,763,691 to Rafferty, entitled “Meter Box Lock Assembly,” is directed to lock assembly for use in combination with an electric meter box or other like enclosure having a bottom, a side wall, and a cover which may be opened to gain access to the interior of the box, and which when closed, overlaps an upper edge of the side wall. The lock assembly includes a bracket having first and second mutually spaced flanges integrally joined by an intermediate web. A jaw is mechanically interengaged with and carried by the bracket for movement between its flanges. The bracket is configured for removable mounting on the side wall, with its intermediate web interposed between the cover and the upper edge of the side wall, and with the first flange and the jaw respectively located adjacent exterior and interior surfaces of the side wall. The jaw is urged towards the first flange to clamp the side wall therebetween, and a cap is secured to the bracket. The cap has a lip configured and dimensioned to overlap and maintain the cover in a closed position.

The McGard Intimidator Sidewinder-Lock™ shown in U.S. Pat. No. 6,742,365 to Sullivan et al, entitled “Ringless Meter Lock,” discloses a locking mechanism for securing the cover of a thin-walled box to the box frame. The locking mechanism includes a clip bracket adapted to engage a wall of the box frame, a lock body adapted to latch to the clip bracket and engage the box cover, a locking member carried by the clip bracket and adapted to clamp the clip bracket to the box wall when the locking member is in a clamping position, and a pivotable actuating lever adapted to actuate the locking member into the clamping position. The locking member and the actuating lever can be implemented as a two-piece system comprising first and second pivoting members. Alternatively, the locking member and the actuating lever can be integrally formed as a one-piece system. The locking mechanism is capable of multiple mounting positions on the box without drilling, and uses a spring-loaded plunger assembly that allows for quick, keyless, slam installation.

There is, therefore, a need for a security bracket and locking apparatus, system, and method for securing at least one structure or a plurality of structures and helping to reinforce same, to secure a utility service enclosure or enclosure generally, and there remains a need for a meter box security device that can be easily and quickly installed, which reliably ensures that the box cover cannot be shut once the support assembly is hung on a wall unless the clamping member and security bracket apparatus is properly secured to a meter box and also minimizes exposed areas of the clamping member comprising a housing to hinder tampering. There is also a need for a meter box security apparatus that offers greater security for preventing unauthorized entry into a meter box. There is also a need for a meter box security device having a reduced number of parts, so as to limit system complexity and minimize manufacturing costs. There further remains a need for an apparatus and method for easily securing and reinforcing at least one structure or a plurality of structures, used with, for example, a utility service enclosure, or more particularly, a watthour meter box having a removable cover with the apparatus being adaptable for use in various configurations.

Those of skill in the art will appreciate the example embodiments of the present invention which addresses the above needs and other significant needs the solution to which are discussed hereinafter.

DETAILED DESCRIPTION OF THE INVENTION

Turning now descriptively to the drawings, in which similar reference characters may denote similar elements throughout the several views, the attached figures illustrate a locking apparatus for securing locking devices and also an interoperable and cooperatively configured security bracket apparatus.

Referring now to FIG. 2, an exploded view of an example embodiment of the invention is shown, comprising a clamping member 70 disposed over a wall portion 60 of a meter box 10; an example of a cooperative security bracket and various aspects the locking apparatus and clamping member can be seen in FIG. 21A-21N. In FIG. 2, clamping member 70 is shown placed over the sidewall 140 in a non-secured position prior to installation. In other embodiments of the invention and those noted herein, and in view of the above, clamping member 70 is disposed over an opposite wall portion 62 of meter box 10. In further example embodiments, clamping member 70 is disposed over a top wall portion 68 of meter box 10. In further example embodiments, clamping member 70 is disposed over a bottom wail portion 64 of meter box 10. In still further example embodiments, clamping member 70 is disposed over a retaining lip 66 disposed on a bottom wall portion 64 of meter box 10.

During installation, clamping member 70 is fastened into place using a clamp actuating member, for example, a fastening lever 120, example embodiments of which are described below. Once clamping member 70 is secured, meter box cover 30 is installed such that clamp actuating member 120 and one end of clamping member 70 are disposed entirely inside an enclosed portion of closed meter box 10, while a fastening shelf 110 remains disposed outside the meter box. In an alternative embodiment, fastening shelf 110 fits inside a slot or other opening in lock housing 80, and the meter box 10 and box cover 30 are fastened together by a plunger type fastener 90 inserted through both an aperture 82 formed in a body portion of lock housing 80 and an aperture 130 formed in a body portion of fastening shelf 110. Sec also example embodiment in FIGS. 22A-22C, security bracket 81 with housing 80 modified as needed to accommodate security bracket 81 and as indicated further herein in FIGS. 21A-21CI and elsewhere and as described).

As seen in FIG. 3, according to a further example embodiment, a fully installed meter box security apparatus comprises a meter box 10 having a box cover 30 installed over the head of watthour meter 20, and a lock housing 80 fastened to a fastening shelf Plunger type fastener 90 is inserted into an aperture formed in a body portion of lock housing 80 and then through an aperture firmed in a body portion of the fastening shelf, thereby securing the lock housing 80 to the clamping member. Lock housing arm 100 in turn holds a meter box cover 30 securely in place so that the meter cannot be tampered with.

Referring now to FIG. 4A, an example embodiment of the invention is shown, comprising a clamping member 70 hung over a meter box wall portion 140. In a specific, non-limiting embodiment, clamping member 70 is a bracket, further comprising a fastening shelf 110 having an aperture 130 disposed at one end and a clamp actuating member 150 at the other end. A plurality of engagement members 180, 210 is disposed on a body portion of the clamping member 70. The particular location of and uses for the plurality of engagement members 180, 210 will vary according to the requirements of the operational environment.

For example, in certain embodiments, engagement member 210 further comprises a clamp 190 having a plurality of engagement surfaces 200, 215. In this particular embodiment, when clamp actuating member 150 is actuated toward a locked position, upper wall portion 140 is securely clamped between engagement surface 215 and clamping member 70 to achieve a reliable and secure installation. In other embodiments, engagement surface 200 also clamps beneath wall portion 140 to ensure a secure fitting. In a further embodiment, engagement surface 215 does not clamp to upper wall portion 140; in this configuration, only engagement surface 200 is secured beneath a portion of wall 140. An isometric view of some of the aforementioned features is shown in greater detail in FIG. 4B.

Referring again to FIG. 4A, when clamp actuating member 150 is rotated about actuable member 180, arced surface 170 contacts clamp 190, and through a cam-type action, sandwiches one (or both) of the clamp engagement surfaces 200, 215 between clamp actuating member 150 and wall portion 140, thereby creating a constant engagement surface along the interface between wall portion 140 and engagement surface 200. In another embodiment, the force applied to actuate clamp actuating member 150 into a fully engaged or secured position is translated and mechanically multiplied by the clamping force imparted by one (or both) of engagement surfaces 200, 215 onto wall portion 140. In certain alternative embodiments, engagement surface 200 includes one or more protruding tabs that grip wall portion 140 with greater force per unit area than would be realized by a constant engagement surface having a greater area.

Referring now to the example embodiment of FIG. 5A, the position of clamp actuating member 150 is shown after it has been fully rotated into a secured position. In certain embodiments, clamp actuating member 150 is rotated until it securely fastens into a notched receiving member 160 cut out of arced surface member 170, the notched receiving member 160 providing a tactile indicator of when the clamp actuating member 150 has reached its fully secured position, and when clamping member 70 is securely fastened to a wall portion 140.

According to one embodiment of the invention, the specific location of notched receiving member 160 permits a terminus end of clamp actuating member 150, when fully rotated and secured, to be contained within an enclosed portion of the meter box even after the box cover has been fully installed. On the other hand, if clamp actuating member 150 is not fully rotated and secured into place, a terminus end of clamp actuating member 150 will protrude from the confines of the meter box, and will therefore not permit final installation of the box cover. In alternative embodiments, notched receiving member 160 is disposed so that the clamp actuating member 150, when fully rotated and secured in place, touches the inside surface of a fully installed box door, but does not interfere with its installation.

In other example embodiments, for example, as seen in FIG. 5B, a stopping member 182 is disposed along the bottom of clamp 190, upon which a bottom surface 162 of clamp actuating member 150 rests when the clamp actuating member 150 is in a fully secured position. In another example embodiment, stopping member 182 is disposed along the bottom of clamp 190 so as to prevent the fastening lever 150 from caroming over a center of rotation. FIG. 5C shows a side view of another example embodiment of clamp 190, wherein stopping member 182 is stamped into or otherwise formed structurally integral with clamp 190. In other example embodiments, a stopping member 182 is affixed to the clamp 190 prior to installation.

In certain embodiments, clamp actuating member 150 is held in a fully secured position by both a frictional force imposed on notched receiving member 160 when the clamp actuating member 150 is fully turned, and by a spring force inherent in the interaction between the leverage on wall portion 140 imparted by clamp actuating member 150 and clamp 190. In other embodiments, clamp actuating member 150 is held in a fully secured position by means of a separate securing means, for example, by means of a latch or a spring (not shown) disposed between the clamp and the clamp actuating member.

Turning now to FIG. 6A, a further embodiment of the invention is shown, wherein a clamp actuating member 400 is attached to a clamping member 410, so that the clamp actuating member 400 rotates about a rotational axis established by the position of engagement means 420. A channel 430 is formed on at least one side of clamp actuating member 400, through which guide member 440 travels during actuation of clamp actuation member 400. During installation, clamp actuation member 400 is rotated about engagement member 420 so that bracket 410 will fit over a box wall 460. To secure the base to the wall, clamp actuating member 400 is then rotated in the other direction, back around engagement member 420, toward a secured position, so that surface engagement member 455 sandwiches wall portion 460 between bracket 410 and surface 455.

Referring now to FIG. 6B, a cut away view of clamp actuating member 400 is provided, wherein a channel 430 and a guide member 440 are shown as non-limiting aspects of the present invention. Clamp actuating member 400 is securely fastened in position after member rotation by means of a stopping shelf 470, upon which rests guide member 440, and also by the inherent spring forces present in the system after clamp actuating member 400 has been fully actuated into a secured position. According to one embodiment of the invention, the desired length and design of channel 430 and stopping shelf 470 is such that the clamp actuating member 400, when secured, is fully contained within an interior space present within the meter box, and does not interfere with installation of a box cover. In another example embodiment, the length and design of channel 430 and stopping shelf 470 are such that the clamp actuating member 400, when fully secured, touches an interior surface of a fully installed box cover, but, again, does not interfere with the cover's installation.

Referring now to FIG. 7A, another exemplary embodiment of the invention is shown, wherein the clamping member 500 is securely fastened to a wall portion 510, and box cover 520 is in a fully installed position. See also example embodiment in FIGS. 22D and 22A-22C, security bracket 81 with housing 80 modified as needed to accommodate security bracket 81 ans as indicated further herein in FIGS. 21A-21CI and elsewhere and as described). Lock housing 540 is affixed to meter box 530 by means of housing arm 545, and by the interaction between plunger type fastener 550 and fastening shelf 560, which has an aperture through which plunger type fastener 550 passes. In other embodiments, plunger type fastener 550 is held in place after installation by means of a retaining member 555. In various other embodiments, lock housing 540 and plunger type fastener 550 are replaced by a single unitary structure, which locks onto fastening shelf 560, thereby securing box cover 520 to meter box 530. In still other embodiments, housing arm 545 fits into a slot (not shown) formed in the box cover 520.

FIGS. 7B and 7C are isometric views of further embodiments of the invention, wherein clamping member 500 and lock housing 540 are shown prior to installation. Fastening shelf 560 fits into a receiving shelf 570 such that aperture 547 lines up with aperture 565. To lock the two pieces together, a plunger type fastener is aligned with aperture 547, and then a body portion of the fastener is pushed through each of apertures 547, 565 and 580. Referring back to FIG. 7A, in some example embodiments of the invention, plunger type fastener 550 is secured in place inside the lock housing 540 by means of one or more retaining members 555. In still other embodiments, the plunger type fastener 550 is formed structurally integral with the lock housing 540.

In another example embodiment illustrated in FIG. 8, there is shown a ringless type meter box 627 that includes a box cover 620, and a box base 619. Formed around an opening in a central portion of meter box cover 620 is a flange 629. A complementary flange is disposed on meter 628 such that, when meter box cover 620 is installed over and around the head of meter 628, the meter complementary flange is encased by meter box cover flange 629, so that the meter cannot be easily removed from the electrical socket unless the cover 620 is first removed from the meter box base 619.

The meter box cover 620 is typically secured in place by means of a small latch assembly, which functions in structural cooperation with a complementary latch-receiving member disposed on the meter box base 619. The meter box cover 620 is used to secure the meter 628 to the electrical socket (not shown), so that completion of an electrical circuit is ensured, and the meter is reliably prevented from falling out of the meter box socket. The meter box cover 620 also prevents unauthorized persons from tampering with the meter 628. As shown in FIGS. 9 and 14, meter box base 619 comprises wall 623. Wall 623 comprises front flange 621 which extends inwardly from wall 623.

Referring now to FIGS. 8, 9, 9A, 10, and 10A, there is shown watthour meter box 627 wherein lock housing 614 may be utilized for securing meter box cover 620 to meter box base 619. The lock housing 614 is generally comprised of a unitary member incorporating a generally perpendicular flange 615 and multiple apertures or openings which may be interconnected such as 617, 622. Opening 617 may extend into lock housing perpendicular to perpendicular flange 615 and extend through opening or aperture 622, which may, if desired, be generally transverse to opening 617. Aperture 622 preferably opens onto an interior side of lock housing 614 and receives fastening shelf 604 of clamping member 602. As shown in FIGS. 9 and 9A, lock housing 614 may be used in conjunction with clamping member 602 such that cover 620 is held in place between flange 610 of clamping member 602 and perpendicular flange 615 of lock housing 614.

See also example embodiment in FIGS. 23A-23E, security bracket items as noted with a housing modified as needed to accommodate security bracket ans as indicated further herein in FIGS. 21A-21CI and elsewhere and as described).

The clamping member 602 is generally comprised of multiple flanges 606, 610, 605 with one of the flanges 606 containing a preferably circular aperture 624 and a fastening shelf 604 that also contains a preferably circular aperture 607. Additional flanges may be added or fewer flanges may be used to accomplish the function as described henceforth.

A locking bracket 601 as shown enlarged in FIGS. 11, 11A, 12, 12A, 13, and 13A may generally comprise clamping member 602 and a fastening lever 603. The fastening lever 603 is generally comprised of multiple flanges 608, 609, 611 with one of the flanges 611 containing a generally circular aperture 625. Additional flanges may be added or fewer flanges may be used to accomplish the function as described henceforth.

As shown in the exploded view of the embodiment of FIG. 12, the fastening lever 603, flexural member 613, and clamping member 602 may be joined through the corresponding apertures 625, 624 with a permanent type fastener 612, which may be a rivet or other type of fastener which allows rotational motion between fastening lever 603, and clamping member 602. Fastener 612 is preferably permanent (but may also be non-permanent and easily removable). Flexural member 613 is partially compressed between the flanges 606 and 611 of clamping member 602 and fastening lever 603. The flexural member is a compressible member which applies a biasing force that biases clamping member 602 and fastening lever 603 preferably away from each other or to separate.

In the embodiment of FIG. 12A, a compression member 630 is adapted to be received by a flange 608 disposed on fastening lever 603. Compression member 630 may be attached to flange 608 by various means, one of which is shown and may comprise a cap. Flange 608 comprises edge 640 and stop surface 641 and is adapted to receive compression member 630 which comprises terminate edge 640A and stop surface 641A. It will be appreciated that edge 640 or terminate edge 640A is a surface although preferably narrow in width and rotates and engages the wall 623 at the same time. Compression member 630 may be wholly or partially comprised of elastomeric material, plastic, or other compressible material. The compressible material may preferably also be resilient so as to permit repeated reuse. The compressible material is also preferably an electrical insulator which reduces any likelihood of contacting electricity which might possibly be present within meter box base 619. Compression member 630 may be used in place of flexural member 613, or in conjunction with it, or with other compression members.

The directly subsequent discussion of assembly and operation of locking bracket 601 onto base 619 of watthour meter box 627 is made using the example of compression member 630, but resilient compression members such as flexural member 613, or other resilient compression members discussed hereinafter, or compression members such as lobe 734 (e.g., See FIG. 17) which may or may not be resilient, may be utilized to provide a secure fit of locking bracket (e.g., 601) onto base (e.g., 619). Compression members may be used with or without each other.

Referring to FIG. 13A, the locking bracket 601 is installed onto the base 619 of the watthour meter box 627 in the following manner: The fastening lever 603 is first rotated to an “open” position as shown with the flange 609 of the fastening lever 603 in a generally perpendicular position to the flange 610 of the clamping member 602. The locking bracket is moved toward the wall 623 of the meter box base 619, shown by movement arrow “A”, allowing the front flange 621 of the meter box base 619 to pass between the compression member 630 disposed on flange 608 of the fastening lever 603 and the fastening shelf 604 of the clamping member 602. The locking bracket 601 is then lowered onto the front flange 621 of the watthour meter box base 619 shown by movement arrow “B” until the front flange 621 of the meter box base 619 is in contact with the flange 610 of the clamping member 602.

Now referring to FIG. 14A, which shows a view on the other side of that shown in FIG. 13A, the installer bears on flange 609 of the fastening lever 603 causing the fastening lever 603 to rotate to a “closed position”, shown by movement arrow “C”. As shown in FIG. 10A, it will be seen that rotation of fastening lever 603 is around axis of rotation 644, which may be generally transverse, perpendicular, or orthogonal to wall 623. In this embodiment, axis of rotation 644 is orthogonal to wall 623, parallel to box cover 620, perpendicular to flange 605, and parallel to a plane of fastening shelf 604. In this embodiment, rotation of fastening lever 603 is in a plane parallel to a plane defined by what might be called the y-axis and the z-axis. In this case, the x-axis would be coincident with axis of rotation 644. Fastening lever 603 would extend into and out of the page in the z-axis. It will be understood that perpendicular or orthogonal is meant to include roughly or approximately perpendicular or orthogonal such that some variation within between about one to ten degrees may occur.

However, axis of rotation 644 could be angled away from wall 623 e.g., by providing that axis of rotation 644 is at an angle with respect to the z-axis and the x-axis while still perpendicular to the y-axis such as by bending flange 606 inwardly toward the interior of meter box base 619. In this case, axis of rotation 644 may still be perpendicular with respect to an axial direction x. In this case, when fastening lever 603 is rotated, then terminate end engagement surface 640A does not come into contact with wall 623 until near the end of rotation, which occurs when stop surface 641A engages the underside of front flange 621. Thus, in this embodiment, at least one axial direction of axis of rotation 644 is perpendicular to the y-axis and/or wall 623.

As the lever 603 is rotated, the compressible member 630, due to the limited space defined by a lower surface of front flange 621 and wall 623 of the watthour meter box base 619 and the terminate end 640A of the flange 608, will compress. The compression of compressible member 630 ensures a “secure feel” and a tighter fit of the locking bracket to the watthour meter box base. The installer continues to rotate the fastening lever 603 until stop surface 641A engages the inside surface of front flange 621. In a preferred embodiment, the flange 609 of the fastening lever 603 is in a generally parallel position to the flange 610 of the clamping member 602 when stop surface 641A engages the inside surface of front flange 621. The front flange 621 of the meter box base 619 is now trapped between the compression member 630 disposed on flange 608 of the fastening lever 603, and the flange 610 of the clamping member 602. As shown in FIG. 15, when meter box lid 620 is installed onto the meter box base 619, then the upper surface 643 of flange 609 may be prevented from movement and/or may be biasingly engaged with the inner surface of box lid 620. The compression member 630, in one example embodiment, provides a bias force between locking bracket 601 and wall 623 and front flange 621 and also frictional engagement which acts to hold the locking bracket 601 securely in place for subsequent attachment of lock housing 614.

Referring to FIG. 16, the meter box lid 620 is then installed onto the meter box base 619. The meter box lid 620 covers the flange 609 of the fastening lever 603 and the flange 610 of the clamping member 602.

Once the lid 620 is in place, the aperture 622 in the lock housing 614 is aligned with the fastening shelf 604 of the clamping member 602. The lock housing 614 is then slid onto the fastening shelf 604 of the clamping member 602, shown by movement arrow “D” in FIG. 13A. The locking shaft 616 is then inserted through the aperture 617 in the lock housing 614, shown by movement arrow “E” which is perpendicular to the fastening shelf 604. Shown in FIGS. 9, 9A, 11, and 11A, the locking balls 618 of the locking shaft 616 become trapped as they pass though the aperture 607 of the fastening shelf 604; this prevents the removal of the locking shaft 616 from the lock housing 614. Fastening shelf 604 may have tapering sides to permit easier insertion or guiding of fastening shelf 604 into aperture 622 of locking shaft 616. Aperture 622 is preferably sized to mate with the sides of fastening shelf 604 at least near flange 605 so as to prevent sideways movement of clamping member 602.

The perpendicular flange 615 of the lock housing 614 prevents meter box lid 620 removal; consequently the meter box lid 620 prevents the fastening lever 603 from rotating to the “open position”. The fastening lever 603, the clamping member 602, the connector 612, lock housing 614, the lid 620, and the meter box base 619, interact together to prevent the removal of both the meter box lid 620 and the entire locking apparatus.

Referring back to FIGS. 9, 10, 11, 12, 13, 14, and 15 when flexural member 613 is utilized, the compressive biasing force so produced between clamping member 602 and fastening lever 603 results in a biasing being applied against both sides of wall 623 of the meter box base 619. On the inner side of wall 623, the periphery 640 of flange 608 of fastening lever 603 is urged into engagement with wall 623. On the outer surface of wall 623, inner surface of flange 605 of clamping bracket 602 is biased toward engagement with the outer side of wall 623. Fastening lever 603 is rotated until stop surface 641 engages the inner surface of front flange 621. In a preferred embodiment, the flange 609 of the fastening lever 603 is in a generally parallel position to the flange 610 of the clamping member 602 when stop surface 641 engages the inside surface of front flange 621. The front flange 621 of the meter box base 619 is now trapped between the compression member 630 disposed on flange 608 of the fastening lever 603, and the flange 610 of the clamping member 602. As shown in FIG. 15, when meter box lid 620 is installed onto the meter box base 619, then the upper surface 643 of flange 609 may be prevented from movement and/or may be engaged with the inner surface of box lid 620. If it is desired to provide biased engagement of flange 609 with inner surface of box lid 620, then compression member 630 may be utilized and/or flange 609 may be provided with resilient compression material that may be in the form of a cap such as the cap shape of compressible member 630, or resilient compression material can otherwise be applied to flange 609.

In an alternate embodiment, compressible member 630 may or may not be used. In this alternate embodiment, a different compressible member, comprising a different shape, material, or attachment means as shown in the illustrations, may be disposed on the inside of flange 605 of the clamping member 602. In this embodiment, as the fastening lever 603 is rotated to a “closed position” as previously described, the flange 623 of the watthour meter box base 619 becomes trapped between the terminate end of flange 608 disposed on the fastening lever 603, and the compressible member, performing a similar function as previously described.

In another alternate embodiment, one or more compressible members may or may not be used. Assuming a compressible material is not used, in this embodiment, as the fastening lever 603 is rotated to a “closed position” as previously described, the wall 623 of the meter box base 619 becomes trapped between the terminate end 640 of flange 608 disposed on the fastening lever 603, and the flange 605 of the clamping member 602.

In another alternate embodiment, shown in FIGS. 17-19, a compressible member may not be used. In this embodiment, the lever 732 comprises an engaging lobe 734. The lever 732 rotates in a generally parallel relationship to flange 738 of clamping member 737. Thus, axis of rotation 745 may be generally orthogonal to metal box cover 720, parallel to wall 723, parallel to flange 735 which engages an outer surface of wall 723, and perpendicular to the plane of fastening shelf 704. Flange 731 is in a generally perpendicular relationship to flange 735 of the clamping bracket 737. As the fastening lever 732 is rotated to a “closed position” as shown in FIGS. 17, 18, the wall 723 of the meter box base 719 becomes trapped between the engaging lobe 734 disposed on the fastening lever 732, and the flange 735 of the clamping member 737.

In another example embodiment of the lever end 609 shown in FIG. 10 is in functional cooperation with a portion 615 of a lock housing mounted to a portion of the clamping member such that the lock prevents rotation of the lever to an open position if the lid is pried upwardly.

In another example embodiment of the apparatus the lever end 609 is in functional cooperation with a portion of a meter box lid 620 such that the lid prevents rotation of the lever to an open position.

In another example embodiment of the apparatus shown in FIGS. 10 and 13 the lever end 609 is at least partially outside the interior of the meter box in a mounting position and at least partially inside the interior of the meter box in a locked position.

Another example embodiment of the apparatus further comprises the meter box. For example, the meter box may have the configuration as shown in FIGS. 1, 8, or that of various other meter boxes suitable for use with the invention.

Another example embodiment of the apparatus further comprises a locking structure (e.g., 614 or other types of locking structures adaptable for use with the invention) for functional cooperation with the clamping member (see, for example, FIG. 11, item 602) for securing a meter box lid to a meter box base.

The reinforcing clip may also be configured for slidable engagement with at least some portion of the opposing flange and/or inner flange to inhibit undesired flexing of the inner flange and/or the opposing flange.

Turning now to FIGS. 21A-21I3 and FIGS. 22A-24CI, other example embodiments of the invention are provided. One example embodiment provides a security bracket apparatus and method, wherein the security bracket apparatus, in some embodiments having an L-shaped bracket configuration, aids in securing a box cover to a meter box when used in conjunction with various suitable locking systems and apparatus. For example, the security bracket apparatus, may be used with a variety of locking systems (for example for use with a locking system of DeWalch Technologies, Inc., (DTI) as described herein in FIGS. 1-21, DTI's locking systems described in U.S. patent application Nos. corresponding to the following DTI products and related Attorney Docket Nos. (in parentheses): Side ProLock (PAT-027 CIPA), Bottom ProLock (PAT-033A), and PowerBar (i.e., Gang Bar—See Application Serial Nos. APPT/EDF No. PAT-062 PPA—PAT-062 PPA3) (See also example embodiment in FIGS. 24A-24I3C, and security bracket items as noted with a housing modified as needed to accommodate security bracket and as indicated further herein in FIGS. 21A-21CI and elsewhere and as described) locking systems, other suitable systems, as well as possibly other devices (e.g., Inner-Tite product referred to as the Jiffy Lock (referred to in the Background of the Invention), McGard, etc.)) (all of the above-referenced patents/patent applications are hereby incorporated by reference herein).

In one example embodiment, the security bracket apparatus 916 is used in combination with the apparatus illustrated FIGS. 1-7C or that illustrated in FIGS. 8-20 to reinforce and aid in securing, for example, a box cover to a meter box enclosure. The security bracket apparatus comprises a securing plate defining an opening 924 adapted to receive a portion of a fastening shelf of a clamping member (e.g., see FIG. 4A, items 110/130 in one example embodiment) wherein the fastening shelf has a first securing means. The security bracket apparatus further comprises, in some embodiments, a multi-function lock housing 914 configured (FIGS. 21J-21N1, items 926, 923) for engaging the securing plate when the multi-function lock housing is mounted to the fastening shelf of a clamping member. With this configuration, the multi-function lock housing 914 cooperatively mounts to the fastening shelf and also engages the security plate forcing it adjacent the side wall of the meter box. A barrel lock 912 or other suitable locking device is inserted into the multi-function lock housing and through an aperture in the fastening shelf to snugly captures the securing plate in place. The security bracket apparatus further comprises, in some embodiments, a flange 925, extending substantially orthogonal with respect to the securing plate. In some embodiment, the flange 925 also extends substantially parallel and in opposing relation to the top flange of the lock housing (e.g., see FIG. 3, item 100). In some embodiments, the flange is adapted to be inserted between the backside wall of the meter box and wall that the box is mounted to. With this configuration, the flange is in spaced cooperative relation to the lock housing flange 100 to effectively sandwich the meter box lid and box together to prevent tampering.

In addition, regarding FIGS. 24A-21N, the security bracket can be modified as shown for use with the PowerBar or gang bar locking system as noted above.

Referring to FIG. 21A, the lock fixture assembly is shown installed onto a watthour meter box assembly 910.

FIG. 21B shows the lock fixture assembly installed on the watthour meter box without the lock 912. It can be seen that the Prolock Body 914 mates into the aperture 924 in the Prolock L Bracket 916.

FIG. 21C shows the lock fixture assembly without the prolock body 914 and lock 912. It shows the aperture 924 in the Prolock L Bracket 916.

In FIG. 21D all the components of the Lock fixture assembly which comprises of the meter box lid 921, meter box 922, Prolock bracket assembly 918, lock 912, prolock body 914 and Prolock L Bracket 916 are shown in exploded view.

In FIG. 21E, which is a cross sectional view of the assembly, the way the parts mate with each other can be seen.

FIG. 21E-FIG. 21I show the various views of the Prolock L-Bracket. The aperture 924 in one of the flanges is to accommodate the prolock bracket assembly lever 917 and the extrusion 926 on the prolock body. The other flange 925 goes behind the box. The flange 925 can be made to various widths, lengths, slots depending on the box. (E.g., see FIGS. 21F-23E)

FIG. 21J shows the features on the prolock body 914, extrusion 926 and the stepped down surface 923, which aid in increasing the effectiveness of the prolock L bracket 16.

In FIG. 21C, the Aperture 924 in the Prolock L-Bracket 916 can be Seen accommodating the lever 917 of the prolock bracket assembly.

The FIG. 21B shows the aperture 924 accommodating the extrusion 926 on the prolock body. It can be seen that the stepped down feature 923 on the prolock body 914 entraps the prolock L bracket 916 which makes it more secure from being pried off.

In use, the prolock bracket assembly 918 is installed onto the meter box 922 and the meter box lid 921 is closed. The Prolock L bracket 916 is installed as shown in FIG. 21C, such that the aperture 924 accommodates the prolock bracket assembly lever 917 and then the prolock body 914 is installed as shown in the FIG. 21B. Finally, the lock 912 is installed to complete the assembly.

In case of attack on the lock fixture while trying to pry it off the meter box the prolock L bracket 916 transfers the force through the flange 925 to the box which is fastened to the wall. This makes it more secure against tampering and aids against prying the lock fixture off the meter box.

All the figures refer to the prolock L bracket 916 being used with the side prolock. It is to be noted that the prolock L bracket 916 serves the same function when used with the bottom prolock too.

Various configurations of the prolock L (or security bracket) bracket can used to serve the same purpose such as:

- a. As shown in FIG. 21K, integrating the prolock L bracket 916′ to the prolock body 914′ by welding.
- b. As shown in FIG. 21L, integrating the prolock L bracket 916″ and the prolock body 914″ by the use of fasteners.
- c. As shown in FIG. 21M, the material height above the aperture on the prolock L bracket 916′″ can be changed and used with the prolock body 914′″ to suit various applications.
- d. As shown in FIG. 21N, extending the prolock body 914″″ to have an L flange 916″″ and 21N1.

The design described does not limit the scope of the invention; the number of flanges may change, or various components may be added or removed to the above-described concept to aid in improved security and operation.
