The present invention relates generally to a securing apparatus, and more specifically, it relates to a securing apparatus for securing at least one structure or a plurality of structures and may be used to secure a utility service enclosure, or for example, a watthour meter socket box to prevent unauthorized access.
For example, in the electric utility industry, 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.
One previously known meter box, for example, 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. In areas such as commercial complexes and apartments, meter boxes are mounted in a multi-meter array called a gang. In order to prevent unauthorized access to the meter boxes, a bar extended across the meter boxes is used to secure them; the bar is locked on both ends of the meter boxes. Some devices used in such applications include a lock device which may be used to individually lock meter boxes or in conjunction with what is sometimes referred to as a gang bar. Other devices include a gang bar with a fixed lock component utilizing a swivel joint such that the swivel joint enables attachment in various configurations. However, unlike other gang bars, the lock and bar are integrated and the combination cannot be attached and effectively used with locks commonly used by industry.
In an attempt to overcome some of these shortcomings, there have been locking devices that can be installed on meter socket boxes. Several examples of patents which disclose attempts to solve some of the above problems are set forth as follows.
U.S. Pat. No. 7,197,905 to Ely et al., entitled “Meter Box Locking Bar Assembly,” is directed to a multi-meter locking bar assembly for locking a plurality of meter boxes of a gang of meter boxes includes a locking bar having opposing first and second ends. A locking device is pivotally fixed relative to the locking bar. The locking device is fixable to one of the meter boxes to lock the locking bar over at least one meter box to lock the meter box. This reference is incorporated by reference herein.
U.S. Pat. No. 5,870,911 to DeWalch, entitled “Electric Meter Box Lock,” sets forth that a lock for meter boxes and similar enclosures includes an outer case with a central bore mounted on an electric meter box. Inside the bore are two extrusions of unequal length spaced 90 degrees apart. A sleeve having a deep bore is held in the case by a screw, and a spring assembly transmits motion from the screw to the sleeve. The sleeve includes a flange at its end with an arcuate cutout portion which spans both extrusions. The sleeve further includes several internal grooves for retaining a barrel type lock which prevents access to the screw. A heavy cover plate is welded to the top of the sleeve so that it overlays and retains the door of the meter box. To unlock the meter box lock, the barrel lock is removed to allow access to the screw. As the screw is unscrewed, the sleeve moves with the screw until the flange on the sleeve clears the shorter extrusion. The sleeve then rotates with the screw until the flange engages the longer extrusion. In this position, the cover plate no longer overlays the door, and the door can be opened. This reference is incorporated by reference herein.

To the accomplishment of the above and related aspects as well as objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated.
These and other aspects, features, and advantages of example embodiments of the present invention will become apparent from the drawings, the descriptions given herein, and the appended claims. Further aspects are also indicated herein in various example embodiments of the invention. However, it will be understood that the above-listed objectives and/or advantages of example embodiments are intended only as an aid in quickly understanding aspects of the example embodiments, are not intended to limit the embodiments of the invention in any way, and therefore do not form a comprehensive or restrictive list of objectives, and/or features, and/or advantages.
In other example embodiments, the present invention provides a securing apparatus for preventing access to at least one structure or a portion of a utility service enclosure such as, for example, a watthour meter box or a plurality of such boxes so as to address the needs as described above.
Another example embodiment of the present invention includes at least an apparatus for securing at least one enclosure, the apparatus being mountable to the at least one enclosure, the apparatus comprising: an enclosure locking member comprising a bracket arm, a fastening member (such as in some embodiments any of a variety of suitable locking devices including barrel locks or plunger locks) and a housing mountable to at least one enclosure; a securing member having first and second ends, the securing member comprising a securing bar and a coupling member being moveably attachable to the securing bar, wherein the coupling member is pivotably mateable with the extended flange (or pivoting arm) of the enclosure locking member.
Another example embodiment of the present invention includes at least an apparatus for securing a plurality of electric meter boxes, the apparatus being mountable to the plurality of electric meter boxes, the apparatus comprising: an enclosure locking system comprising first and second enclosure locking members each comprising a bracket arm, a lock, and a housing mountable to at least one meter box; a securing member having first and second ends, the securing member comprising a securing bar, first and second coupling members each being moveably (in some embodiments pivotally or rotatably) attachable to the securing bar, and wherein each coupling member is moveably mateable or engageable with an extended flange of the bracket arm of its respective first or second enclosure locking member.
An example embodiment further provides an apparatus adapted to be mounted to secure at least one enclosure, the apparatus including at least: first and second enclosure locking members comprising a body portion and a mating portion; and a securing member having first and second ends with the securing member comprising a securing bar and first and second coupling members with each being moveably attachable to the proximal distal ends of the securing bar, wherein the first and second coupling members are separably mateable with a mating portion of each of the respective first and second enclosure locking members. In a further example embodiment, the apparatus above is provided wherein the at least one enclosure has a wall and sidewall and a cover oriented generally perpendicularly to the sidewall, wherein body portion of each of the first and second enclosure locking members forms a recess, the recess being adapted to receive a fastening member for fastening the enclosure locking member to a wall or sidewall. In still a further example embodiment, the apparatus above is provided wherein the recess is further adapted to receive a barrel lock comprising a generally cylindrical body with one or more retractable locking elements extending therefrom, wherein the barrel lock may be received and secured in the body portion in such a way as to protect the fastener from tampering.
A general purpose of the present invention, in an example embodiment, which will be described subsequently in greater detail, is to secure at least one structure or a plurality of structures, to prevent unauthorized access, for example, to secure a utility service enclosure, such as for example, a meter box having a removable panel or lid.
In another example embodiment, the present invention comprises an adjustable vertical telescopic tube assembly. Alternately, the horizontal members provide positional adjustment along the vertical axis defined by the tube. The adjustability enables the user to successfully attach the gang bar to any myriad of meter box size combinations that may occur in the field. Variation of box sizes, configurations, spacing and condition often negatively affects the ability of user or installer to successfully attach an non-adjustable gang bar. Additionally, many geographic markets have different meter box standards, which thereby requires a producer to offer many variations of same product with fixed horizontal members in axial positions specified by customer. Customization negatively affects a producer's production cost, inventories and fulfillment responsiveness. An adjustable assembly benefits customer and producer.

Low-profile lock assembly accessories include at least: a spacer to enable attachment to a meter box on sides other than top (as top orientation allows overhang of housing); an attachment tool that fully seats receiver arm into housing (this tool is necessary when the enclosure is so deformed that the gang bar assembly makes it difficult to properly align receiver within housing to enable lock insertion); in some example embodiments, the receiver arm functions in a similar manner as the coupling member (or link) described herein with regard to other embodiments of the securing apparatus. It mates with the securing apparatus or gang bar telescopic assembly and housing to secure a meter box. An example aspect of the example embodiment of the present invention is to secure a gang of watthour meter boxes from unauthorized access. Another aspect of the invention is to lock boxes whose side access limitation prevents direct attachment of a lock device. Another aspect of the invention is to provide the ability to lock enclosures surrounded by physical encumbrances that significantly limit available space for attaching a locking device. Another aspect of the present invention is to secure a gang of enclosures with hinged openings. Another aspect of the invention is to secure a large cabinet with multiple doors.

Referring now to
Referring generally to FIG. s 1-20, an example embodiment of the present invention comprises an enclosure locking member 12, and a securing member, wherein the enclosure locking member comprises a bracket arm 18 which comprises an extended flange and a housing 14 comprising a recess 42, and a receiving bore, and wherein the enclosure locking member 12 further comprises a housing screw (disposed proximate the end opposite the receiving bore opening of the enclosure locking member housing, being disposed for releaseably affixing the bracket arm with respect to the housing 14), attaching screw 36, and, in some example embodiments, a lock 16 (which may be a specially configured and modified lock for use with conventional locking devices (such as barrel or plunger locks or any other suitable conventional locking device) or adapted for use with complementarily adapted or modified locking systems (e.g., of DeWalch Technologies) including barrel or plunger locks and attaching hardware (e.g., such as DeWalch Side or Bottom ProLocks or Armadillo Locking hardware (for example, see U.S. Pat. Nos. 7,176,376, and 5,870,911, and application Ser. No. 12/317,086 and also REFERENCES section below)), and wherein the securing member comprises a securing bar (which, in some embodiments has an adjustable, variable length and comprises a telescoping rod and tube 30, 32, and, in other example embodiments, comprises only a rod), and wherein the securing member comprises a coupling member (e.g., either or both 10, 28, for example, in
Another example embodiment comprises an enclosure locking member 12, and a securing member (in some example embodiments comprising 10, 32, 30, 28), wherein the enclosure locking member comprises a bracket arm 18 which comprises an extended flange and a housing 14 (the housing, in some embodiments (e.g., similar to a portion of a DeWalch Technologies product referred to as the Armadillo, U.S. Pat. No. 5,870,911) comprising a recess, and a receiving bore), and wherein the enclosure locking member further comprises a housing screw, attaching screw, and, in some example embodiments, a lock (which may be a specially configured or conventional barrel or plunger lock), and wherein the securing member comprises a securing bar (which comprises a rod and tube (extendable) 30, 32 (in some example embodiments) or only a rod (in some or other example embodiments), and wherein the securing member comprises a coupling member (or a link in some embodiments) (and in some embodiments, first and second coupling members 10, 28), wherein the coupling member comprises a flange 1, flange 2, receiving cavity, opening (or through hole), and tab, and wherein the securing member further comprises a barrel nut (e.g., or sex nut or other suitable fastening structure) and a carriage bolt, and wherein the receiving cavity is adapted to rotatably (or translationally) receive the extended flange of the bracket arm to engage the securing member to the enclosure locking member (see for example, some embodiments shown in
In one example embodiment, enclosure locking member 12 comprises a housing 14 into which a bracket arm 18 is inserted into a receiving bore and fastened with a housing screw for which mating counter rotation features ensure immobility of components. Referring generally to
As noted herein, in another example embodiment, the securing apparatus comprises just the coupling member and securing member (without the enclosure locking member(s)) and may be universally useable and interchangeable with other devices similar to the enclosure locking members which would serve as attaching structures.
In an alternate embodiment, the enclosure locking member is a single body component that attaches to an enclosure with a bracket mechanism and a lock (e.g. used with DeWalch Technologies, Side or Bottom ProLock devices) (being reconfigured and having complementary engageable structures) (a portion of which is shown generally in
Regarding the enclosure locking member, the barrel lock, in some embodiments, is a common product used in the utility industry that conforms to two standard barrel lengths and a common diameter (and in some embodiments other lengths and sizes). Internal components and functionality varies by vendor and model to provide many varieties of keys to provide exclusive ability to open locks.
In an example embodiment, the securing member comprises a securing bar having first and second ends and further comprises first and second coupling members rotationally attached to the ends respectively. In another example embodiment, the securing member comprises a securing bar having first and second ends and further comprises a first coupling member rotationally attached to a given end of the securing bar.
The securing bar can be comprised of a single rod or a rod and tube as an extendible and retractable assembly. In the single rod embodiment, the rod has at each end a through hole or opening that is normal to and intersecting, in some embodiments, with the rod axis. In the rod and tube embodiment, the tube has fixed at one end a protruding rod having a through hole normal to and intersecting the rod axis. The rod slides within tube to both extend and retract allowing variable length adjustment as desired depending on, for example, the number of boxes to be secured.
The coupling member, in an example embodiment, has two flanges at one end that are of similar size and shape and have axially aligned through holes. A barrel nut (e.g., in some embodiments referred to as a sex nut) and carriage bolt join flanges 22A, 22B (e.g.,
Thus, the coupling member and bar attachment is supported on two opposing flanges that are structurally supported by perpendicular walls (e.g.,
In another example embodiment, the securing apparatus cooperates with an alternate enclosure locking member configured similarly, except the housing screw is obviated. As such, secure attachment requires insertion of a lock.
It will also be recognized, in some example embodiments, when coupling members are attached at both ends of an enclosure gang, the securing bar spans the distance between coupling members and, thereby, mechanically interferes with opening enclosure lids or doors.
Turning now to
In another example embodiment,
In another example embodiment, the thickness of the flange on the bottom side is reduced (e.g., of the ProLock housing) (the flange usually contacts an enclosure lid to accommodate the material thickness of the coupling device). The thinner flange functions effectively because of the support provided by the physical encasement of metal walls by the coupling member receiving cavity.
Another example embodiment provides a configuration which increases the relative position of the ProLock housing flange and bracket receiving cavity by an amount equal to the material thickness of the coupling member. This embodiment requires the coupling member receiving cavity height to increase sufficiently for the ProLock housing flange to be insertable.
Another example embodiment provides a configuration which incorporates changes in either one of the two example embodiments, immediately above, with the modification of the coupling member by adding an extending formed surface of the receiving cavity creating a flange that extends to the outermost edge of the ProLock. In the flange a through hole of a diameter closely matching the lock is added and located in alignment with the lock cavity of the ProLock housing. When the lock is inserted in ProLock housing the lock head extends into the coupling member flange hole creating an additional mate with the ProLock system. Thus the lock creates a positive attachment to the bracket attached to the enclosure and the coupling member.
It should be further emphasized that in some embodiments, the securing apparatus comprises only the coupling member or members and the securing member. In such an embodiment, the securing member may be used with other locking devices in the industry. For example, the coupling member receiving cavity could be modified in size, shape, and configuration to accommodate and receive tabs or brackets from other types of locking devices so as to secure the securing member to gang or meter boxes. In this way such a configuration would be more universal in its applications. Moreover the enclosure locking device can also be adapted to receive other locks, barrel, locks used in the industry and a seal or wire seal could be used to indicate any tampering.
In another example embodiment, it will be appreciated that the coupling members may be configured to be is separably and slidably (e.g., translationally along the longitudinal axis of the coupling member) mateable or engageable, or alternately pivotably or rotationally attachable with respect to an appropriately adapted extended member of the bracket arm of their respective first or second enclosure locking member.
In other embodiments, first and second coupling members could also each be moveably (in some embodiments pivotally or rotatably) attachable along the length of the securing bar and/or at the ends of the securing bar.
In an example embodiment, the securing apparatus 8 is adapted to secure a plurality of electric meter boxes, the apparatus being mountable to the plurality of electric meter boxes. In one embodiment, the apparatus comprises first and second enclosure locking members 10, 28 each comprising a bracket arm, a lock, and a housing mountable to at least one meter box, a securing member having first and second ends, the securing member comprising a securing bar, first and second coupling members each being moveably (in some embodiments pivotally or rotatably) attachable to the securing bar, and wherein each coupling member is moveably mateable or engageable with an extended flange of the bracket arm of its respective first or second enclosure locking member.
In some embodiments, the securing apparatus comprises at least one locking member (or device) 12 (see
In another example embodiment, the securing apparatus comprises at least one enclosure locking member, a securing member (which may have a fixed length, or in other embodiments, a variable length) having first and second ends with the securing member comprising a securing bar and at least one coupling member being moveably (in some embodiments pivotally or rotatably) attachable to a proximal ends of the securing bar. In other embodiments, the coupling member may be rigidly fixed to the securing bar and/or the enclosure locking members. In still other embodiments, the enclosure locking member(s) may be rigidly attached (e.g., by welding or fasteners, adhesives, or otherwise known to one of skill in the art) directly to the ends or intermediate the ends of the securing bar and/or the coupling member.
In other embodiments, one and/or both ends of the securing apparatus may be secured to structure other than a meter box (e.g., a wall, bracket, tree, other suitable anchoring) with the enclosure locking members or any of a variety of fastening or securing structures.
In an example embodiment, the coupling members are pivotally or rotationally attached or alternately separably and slidably mateable with an extended member or mating portion, or bracket arm of each of respective first and second enclosure locking members 10, 28. It should also be noted that enclosure locking members 10, 28 may have an identical configuration in some embodiments or different in other embodiments.
For the following paragraph and description regarding
For the following paragraph and description regarding FIGS. 35A1-35C, 35D1-35D5, reference numerals apply only to these figures and not to other figures herein. Referring to FIGS. 35A1-35C, 35D1-35D5, receiver 1 is shown mated with housing 2 by way of a T-slot 22 in the housing and T-body 11 on receiver. To lock assembly, barrel lock (not shown)is inserted into orifice 21 and saddle feature 13. When locked, items 13 and 21 must be concentrically aligned. The receiver pivotally attaches to the securing apparatus or gang bar. The gang bar rod inserts into slot 12 and pivot 3 inserts through hole 13 into a pivot hole in the gang bar rod. In an example embodiment, pivot threads 32 into a flat bottom tapped hole 14 that is axially aligned with through-hole 13. Pivot surface 31 interacts with the gang bar rod pivot hole. The pivot head 33 is mounted or submerged flush into countersunk hole 13. A sloped surface (item 25), cooperates with the assembly tool 4 shown in FIGS. 35A2 and 35C-35D1. The housing has a front face 26. The housing overhang surface 27 interacts with item 15, the flat surface on receiver 1 where the T-body terminates at a larger outside diameter. Structures 27 and 15 along with T-slot and T-body interaction cooperatively resists an attacker from applying a moment to the lock in all but one axis and forces in all but one direction. Defeating the assembly would require the entire shaft to fully shear in two locations, which is extremely difficult. Housing 2 attaches to meter box 9 with bolt 8 that passes from inside of enclosure 9, through bracket accessory 7 or alternatively a washer of some varied configuration, then a hole punched in the enclosure and, then threads into 24, as shown in FIG. 35D2. FIG. 35D4 shows the substantial surface 29 interacting with enclosure surface to effectively distribute any mechanical loads imposed by attack. The housing 2 orientation is controlled by overhang face 23 in cooperation with enclosure flange 91 shown in FIG. 35D2. Overhang face 23 and orientation of lock engagement that enables low profile of housing 2 and low position of lock orifice 21. The position and orientation provide a selected and desired novel configuration. When the locking assembly is used on either side or bottom of meter box, a spacer 6 of
Various other example embodiments provide an apparatus that may be adapted for use on a utility service enclosure. Such a utility service enclosure is used not only in the electric utility industry (e.g., a meter box) but also in the gas, water, cable, TV utility industries or in other utility industries.
Various other example embodiments provide a securing apparatus that may be adapted for use on a utility service enclosure or on other enclosures needing a locking apparatus. Such an apparatus may be used to secure doors, covers, hatches, access panels for any type of enclosure, container, or to secure a number of adjacently positioned containers together or prevent doors or covers of same from being opened. Moreover, a utility service enclosure or other containers, for example, may have various configurations, shapes and sizes and be used in the electric utility industry, (e.g., a meter box) as well as in the gas, water, cable, TV utility industries and the securing apparatus may be configured to accommodate and secure such various configurations.
As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. However, several example embodiments are further provided hereinafter.
The method of use by step, in one example embodiment, is as follows:
In another possible embodiment, alternately, for enclosure locking devices whose bracket members radially move within housing and hold two discrete positions (e.g. DeWalch Technologies, Armadillo device), the method offers a less physically strenuous method as follows:
Both example methods above offer a less physically strenuous and awkward assembly than some conventional devices whose enclosure locking member bracket members are fixed to bars. For such products, massive assemblies freely spin during steps 5, 6, 7. Another step may be to partially screw bracket member into housing and position flange.
As briefly noted above and further explained herein, many commercial complexes and apartments have watthour meter boxes that are mounted in a multi-meter array called a gang. In order to prevent unauthorized access to the meter boxes, a bar extending across the meter boxes is used to secure them which is locked on both the ends to a meter box. The bar interferes with the opening or removal of a meter box lid. The present invention is adapted to provide locking capability for use in various configurations to secure a gang of watthour meters from unauthorized access by providing a higher security and ease of installation.
In an example embodiment, a telescopic bar comprises swiveling coupling members mounted at the distal ends of the telescopic bar, wherein the coupling members mate to respective enclosure locking members attached at each end of a meter box gang. The swivel integrated with the bar enables multiple attachment configurations and facilitates operator usage. Locking and unlocking of lock devices, in some example embodiments, enables the attachment and detachment of the telescopic bar. When detached, all meters within the gang are accessible. Thus, the telescopic bar can be used repeatedly.
In another example embodiment of the present invention, a securing apparatus provides access security on any gang of enclosures or large cabinet with a lid or door. Such applications might include large telephone, network or power station switch boxes. Any gang of enclosures with multiple access points may be secured in this fashion to improve upon, replace or solely provide access security. Furthermore, the securing apparatus could be used to secure gates or passage ways that might require protection, reinforcement or fortification.
In an example embodiment, the securing apparatus comprises a securing member, first and second coupling members, and first and second enclosure locking members. The coupling member comprising a tab, cavity, adapted for receiving a portion of the enclosure locking member.
In some embodiments of the invention, the securing apparatus can be adapted for use to secure just one meter box.
In other embodiments, a securing apparatus is provided for use with other locking devices. The securing apparatus is adapted to be mounted to such locking devices or systems (possibly other such locking systems used by other in the industry and well know to a person of ordinary skill in the art) to secure a plurality of electric meter boxes. In one embodiment, the securing apparatus comprises a securing member having first and second ends with the securing member comprising a securing bar (e.g., in some embodiments similar to items 30, 32) and first and second coupling members (e.g., in some embodiments similar to items 22/20,
Turning now to
The securing apparatus 208 can be attached to enclosures (e.g., switching boxes for telephone companies, electrical substation enclosures or an array(s) of enclosures, lockers for security (e.g., storage, gym, ski, or other lockers or enclosures), enclosures containing switches, circuit breakers, etc.), in various orientations or modes. In some non-limiting example embodiments, the securing apparatus 208 can be adapted for attachment in a substantially horizontal mode and/or in a substantially vertical mode. However, the securing apparatus could also be modified (e.g., by suitably reconfiguring and mounting the projecting members in a non-perpendicular orientation with respect to the outer surface and/or longitudinal axis of the securing member) so that it could be mounted in a non-horizontal or non-vertical orientation (e.g., diagonally or otherwise) on a gang of meter boxes in such a way that the projecting members extend over and prevent the box covers form being opened. In the horizontal mode, as briefly noted above, the securing apparatus enclosure locking members (sometimes referred to as devices) are usually attached furthest from the hinge of an enclosure or enclosures; in many cases, the hinge is usually toward the bottom of the enclosure. For example, in one possible non-limiting embodiment, the securing apparatus may be used with an enclosure such as a watthour meter box. The extendable securing member (or in some embodiments, a bar) ideally covers the full distance of the hinge. In an example embodiment, the overall length of the securing member is sufficient to extend substantially horizontally across the width of a meter box or a gang or group of meter boxes positioned, for example, side-by-side next to one another. However, in other embodiments, the securing apparatus may be oriented diagonally across one or more enclosures (or meter boxes in an example embodiment).
Some example embodiments the securing member may be adapted for use in a substantially vertical mode or orientation. In the vertical mode, as shown in
In an example embodiment, horizontal members are fixedly mounted to the securing member. In another example embodiment, the securing apparatus further comprises, horizontal mounted, fixed in some embodiments and moveable in other embodiments (e.g., reattachable at various location or securable on a rail-like system). The horizontal members are configured and adapted to extend across the lid to provide similar protection as that provided by the securing apparatus when in a horizontal mode. In an example embodiment, at noted above, the design is benefitted by adding fixed horizontal members to the bar member that extend across the lid to provide similar protection as that provided by the horizontal orientation. These horizontal members can be fixed by welding, a suitable threaded or other type of fastener, pin and hole, rivet or any other suitable method or by other methods and fasteners known to a person of ordinary skill in the art. In other example embodiments, as noted, the horizontal member may be moveably mounted to the securing member. For example, non-weld solutions can offer in the field adjustment of position, which can be beneficial to the user (for example, translatable, slidable (e.g., the extendable securing member may comprise rails on a rail-like structure). The design usually includes an anti-rotation feature provided by a fixed protrusion extending in opposite direction of horizontal members. That is, in an example embodiment, two welded L-brackets are provided to enable vertically oriented attachment on either side of enclosures. The L-shape mates with the corner of the enclosure. In an alternate embodiment the horizontal member extends on both sides of the bar member.
In other embodiments barrier members 204 may be attached without welding and may be configured to be detachable or adjustable which provides more flexibility in installation, usage and mounting. In other embodiments lid barrier members 204 may be welded in a predetermined location and non-adjustable. Because gang bar devices may be primarily used as retrofit equipment for existing meter installations, the ability of the user to adjust locations of 204, would enable installation on a greater variety of meters and meter configurations as well as other types of enclosure or lockable enclosures or containers. It is further anticipated that items 202 and 204 could be integrated into a single adjustable component that translates along the tube and can be set into a fixed location to provide a suitable security function.

Another embodiment related to, for example, at least a method of manufacturing structures, enclosures, devices, or for example in some embodiments, utility revenue protection apparatus, devices and components and related to methods of processing material used for the above is also provided herein (See generally
Test measurements of surface harness for subject low carbon steel on the Rockwell C scale are 70+ from ferritic nitrocarburizing and up to 60 from carbonnitriding. The purpose of these processes is to diffuse nitrogen and carbon atoms in a solid solution of iron, thus entrapping the diffused atoms in the interstitial lattice spaces in the steel structure. Time, temperature and environment are the controlling variables of case hardening. Depth of case at a given environment and temperature is controlled by time. In some embodiments, a higher strength device have improved durability, ductility, hardness is produced. Moreover, when such processes are used to manufacture such structures as noted herein, various benefits result including a notable reduction in the deformity of various components. In this way, the interoperability, engagement and intercooperation between various structures in embodiments as noted herein is improved.
In the Revenue Protection industry, carbonitriding is the standard process for low carbon steel, because of effectiveness and low cost. Harness measurements of competitor products consistently fall in the Rockwell C range of 50-60. Observations and specifications indicate carbonitriding is the exclusive process in the industry.
Carbonitriding low carbon steel requires heating above the critical temperature (about 1340° F. depending upon alloy composition) causing phase transformation from ferritic to austenitic to a range of 1400° F. to 1600° F. within an atmosphere usually comprised of an enriched carrier gas from an endothermic generator, plus about 10% anhydrous ammonia for usually about 20-30 minutes. Maximum surface hardness usually obtained by oil quenching directly from the carbonitriding temperature. Unfortunately, part deformation often occurs during quenching, but this can be minimized by quenching in hot oil. For the long tube and rod in the gang bar and especially the vertical design with the horizontal attachments, in accordance with some embodiments as noted herein, deformation can ruin the work product or require significant additional labor to make certain or all parts useable. For example, warpage can occur along the longitudinal axis or radial axis (e.g., in a cross-sectional view), impairing telescopic (or slidable, rotational) cooperation between and relative operability of the tube and rod as well as other heat treated components. This is a further problem in view of the horizontal attachments This rework often includes heat application that reduces the desired high surface hardness. Also of concern is the core metal below the case hardening that may have a brittle structure from quenching. Tempering the steel at 300 to 400° F. can reduce brittleness without appreciable impairment of case hardness.
A thermochemical treatment called ferritic nitrocarburizing is a superior method, though more expensive, when heat treatment induced deformation or very high surface hardness matters. The process, like carbonnitriding, exposes the steel to an environment enriched with nitrogen and carbon at elevated temperature; however, it is heated to only about 1100° F., which is below the critical temperature and, consequently, the steel remains ferritic. Quenching from this lower temperature yields comparatively negligible distortion. The chemical environment can be a gas, cyanide salt bath, or in one example embodiment, a bath of powder chemicals. Contributing to the higher cost is the long process time of many hours. Importantly, the core material below case depth remains significantly unchanged and retains original as milled mechanical properties including ductility.
For security products that can tolerate the higher processing cost or economically benefit from reduced deformation or require superior surface hardness, ferritic nitrocarburizing is superior to other case hardening processes. The 17%-27% higher hardness is a significant improvement in attack resistance. Finally, in the case of the gang bar, the productivity improvements from reduced deformation are considerable because minimal deformation means significantly higher process production yield. Consequently, the economic benefits of the productivity gains far exceed the higher cost of ferritic nitrocarburizing.
Ferritic Nitrocarburizing Process. Despite the name, the process is a modified form of nitriding and not carburizing. The shared attributes of this class of this process is the introduction of nitrogen and carbon in the ferritic state of the material. The processes are grouped into four main classes: gaseous, salt bath, ion or plasma, or fluidized-bed. The trade names and processes (patented in some cases) may vary slightly from the general description, but they are all a form of ferritic nitrocarburizing.
Salt bath ferritic nitrocarburizing. Salt bath ferritic nitrocarburizing is also known as liquid ferritic nitrocarburizing, liquid nitrocarburizing, liquid nitriding, or salt bath nitriding. It is also known by the trademarked names Tufftride and Tenifer.
The most simple form of this process is encompassed by the trademarked Melonite process, also known as Meli 1. It is most commonly used on steels, sintered irons, and cast irons to lower friction and improve wear and corrosion resistance.
The process uses a salt bath of alkali cyanate. This is contained in a steel pot that has an aeration system. The cyanate thermally reacts with the surface of the workpiece to form alkali carbonate. The bath is then treated to convert the carbonate back to a cyanate. The surface formed from the reaction has a compound layer and a diffusion layer. The compound layer consists of iron, nitrogen, and oxygen, is abrasion resistant, and stable at elevated temperatures. The diffusion layer contains nitrides and carbides. The surface hardness ranges from 800 to 1500 HV depending on the steel grade. This also inversely affects the depth of the case; i.e. a high carbon steel will form a hard, but shallow case.
A similar process is the trademarked Nu-Tride process, also known incorrectly as the Kolene process (which is actually the company's name), which includes a preheat and an intermediate quench cycle. The intermediate quench is an oxidizing salt bath at 400° C. (752° F.). This quench is held for 5 to 20 minutes before final quenching to room temperature. This is done to minimize distortion and to destroy any lingering cyanates or cyanides left on the workpiece.
Other trademarked processes are Sursulf and Tenoplus. Sursulf has a sulfur compound in the salt bath to create surface sulfides which creates porosity in the workpiece surface. This porosity is used to contain lubrication. Tenoplus is a two-stage high-temperature process. The first stage occurs at 625° C. (1,157° F.), while the second stage occurs at 580° C. (1,076° F.).
Gaseous ferritic nitrocarburizing. Gaseous ferritic nitrocarburizing is also known as controlled nitrocarburizing, soft nitriding, and vacuum nitrocarburizing or by the tradenames NitroTec, Nitemper, Deganit, Triniding, Nitroc, and Nitrowear. The process works to achieve the same result as the salt bath process, except gaseous mixtures are used to diffuse the nitrogen and carbon into the workpiece. In this embodiment we use Corr-I-Dur® which is an alternative to salt bath nitriding with oxidation.
The parts are first cleaned, usually with a vapor degreasing process, and then nitrocarburized around 570° C. (1,058° F.), with a process time that ranges from one to four hours. The actual gas mixtures are proprietary, but they usually contain ammonia and an endothermic gas. (See last two references listed under “References” below). In an example embodiment, a process for treating revenue protection security devices utilizing telescoping tube and rod configuration or structure (as well as in possible embodiments other members, components, and/or structures could also be treated as suitable) is provided. The process includes at least the steps of: procuring stock tubes and rods conforming to dimensional and ferrous material composition specifications; machining rods and tubes to specification with features necessary for cooperation with additional components of entire security device; welding short rod to one end of tube where rod is partially inserted into tube and a fillet weld bonds the circumferential intersection entirely or partially, and wherein the other tube end remains open for accommodating sliding relationship of the tube and inserted long rod; placing a stack of rods or tubes into a chamber sufficiently dense to maximize economy while exposing treatment surfaces to environment; performing ferritic nitrocarburizing to create hardened surfaces with a depth of 0.002 to 0.005 inch by: i) supplying the chamber with a highly enriched atmosphere of nitrogen and carbon, usually provided by 40:60 mixture of methane and ammonia at an elevated temperature of 1100° F. to nitrocarburise the outer surfaces in a single treatment step for a time of 2 to 3 hours; and ii) packing parts within proprietary bath of powder chemicals that provides an enriched environment of nitrogen and carbon at an elevated temperature of 1100° F. to nitrocarburise the outer surfaces in a single treatment step for a time of 2 to 3 hours; and removing the stack of rods or tubes from the chamber. In an example embodiment, the above process also may be provided wherein the tubes or rods are finished machined before being stacked in heat treat chamber, so that after the nitro-carburizing process they require no further machining or forming or reworking prior to use. Parts may be treated for corrosion resistance before ready for use. In an example embodiment, the any of the above processes also may be provided wherein the rods and tubes have a minimal gap when assembled, and are to form a telescoping rod and tube assembly, the rods and tubes being stacked in heat treat chamber with their gaps open. The above processes may also be modified for different components, member and/or other structures having a variety of geometries and configurations.
