- the apparatus is used for securing a watthour meter socket ring so as to prevent the separation of two opposing members of the watthour meter socket box ring.
- the apparatus may be used for creating a tamper-evident seal by securably connecting a plurality of structures.
- the apparatus may also be used as a locking assembly with at least one structure as will hereinafter be explained in further detail.
- both the meter and meter base incorporate a corresponding set of flanges (not shown) that are retained together with an annular, lockable sealing ring 2 .
- the lockable sealing ring 2 is designed to encase and captivate the corresponding flanges of the meter and base when the ends 9 A, 9 B of the sealing ring 2 are held or connected together.
- a plunger type lock is typically used that is adapted to hold the ends of the sealing ring together.
- FIG. 2 shows a plurality of structures 9 A, 9 B having apertures 12 A, 12 B which may be any of a variety of structures.
- the plurality of structures comprise first and second ends 9 A, 9 B of a ring 2 , which may be connected or disconnected, the ring being adapted to mount a meter to a meter box structure (not shown).
- Each of the first and second ends 9 A, 9 B of the ring 2 defines apertures 12 A, 12 B therein respectively.
- a lock 19 and a retaining sleeve 1 is adapted to be installed onto a watthour meter box sealing ring 2 .
- FIG. 2 shows the lock 19 prior to the lock being retained by retaining sleeve 1 .
- the lock 19 has a head member 6 and a shank portion 8 , which in one example embodiment is a shaft member.
- the lock 19 further comprises at least one and preferably two moveable locking members 4 A, 4 B (but may include a plurality of lock members having various other suitable configurations adapted for locking engagement).
- the shaft member 8 is insertable through an aperture 12 A formed in the first end 9 A of the sealing ring 2 . In this way, the lock 19 may be viewed as being mounted to the first end of the sealing ring.
- a retaining sleeve 1 is adapted to capture the shank portion or, for example, shaft member 8 wherein the lock 19 is retained on the first end 9 A of the sealing ring 2 .
- the shank portion may be viewed as being between the first and second ends 9 A, 9 B of the sealing ring 2 .
- a receiving member 3 in alternate example embodiment is adapted to secure the moveable locking members 4 A, 4 B of the shank portion or shaft member 8 with the first and second ends 9 A, 9 B of the ring 2 held between the receiving member and head member 6 .
- the shank portion comprises a shaft member 8 with an outer surface defining a cylindrical groove 21 .
- the retaining sleeve preferably has an axial bore adapted to receive at least a portion of the shaft member 8 with the retaining sleeve adapted in surrounding relation with at least a portion of a cylindrical groove 21 so as to slidably capture the shaft member 8 .
- the groove may only extend around a portion of the shaft or be configured like a slot or have another configuration suitable for slidable engagement and capture by the retaining sleeve 1 .
- the lock 19 generally collectively comprises the head member 6 , the shaft member 8 , preferably multiple moveable locking members 4 ideally having a spherical configuration (or cylindrical or other configuration), the cylindrical groove 21 disposed on the shaft member 8 , and a biasing structure.
- the biasing structure is preferably a plunger 5 and a spring 7 .
- the retaining sleeve 1 is generally comprised of an aperture 20 , a radial groove 13 , a captive shoulder 4 , and a retaining flange 16 .
- the lock shaft 8 When in the “unlocked” position, the lock shaft 8 , is adapted to pass through an aperture 12 disposed on a sealing ring member 9 and forcibly receive retaining sleeve 1 .
- the retaining sleeve 1 As the retaining sleeve 1 is engaged closer to the head member 6 , the retaining flange 16 will collapse into the space defined by the cylindrical groove 21 disposed on the lock shaft member 8 . This allows the retaining sleeve 1 to freely slide in opposing limiting axial positions, and consequently, captivating the sealing ring member 9 between the lock head 6 and the retaining sleeve 1 .
- the groove wall 17 disposed on the lock shaft 8 interferes with the retaining flange 16 , preventing the retaining sleeve 1 from separating from the lock shaft 8 .
- the radial groove 13 captivates the locking members 4 and will not allow the plunger 5 to pass though them and into the “locked” position. This ensures that a constant force is applied to the wall of the radial groove 13 of the retaining member 1 .
- the retaining sleeve 1 When the tip of the lock shaft 8 is inserted into the aperture 10 of the lock receiving member 3 , the retaining sleeve 1 bears against the entry perimeter of receiving member 3 until the applied force exceeds the resistive force created by the interference between the spherical locking members 4 and the captive shoulder 15 , allowing the retaining sleeve 1 to slide toward the rear of the lock shaft 8 (closest to the lock head) and away from the spherical locking members 4 . This allows the lock shaft 8 to fully enter the lock receiving member 3 until the spherical locking members 4 can expand into the radial groove 11 (“locked” position). When the lock 19 is unlocked and pulled away from the lock receiving member 3 , the retaining sleeve 1 is forced back to the “preloaded” position, retaining the spherical locking members 4 once again.
- the retaining sleeve may also serve as a spacer-like member between a plurality structures, with the retaining sleeve being dimensioned as required to set apart the structures as desired. It may also be made of an insulating material and used as a retaining member and/or insulating member as well as a spacer.
- FIG. 6 Another example embodiment of FIG. 6 comprises a combination 50 of the lock 19 , first and second ring ends 9 A, 9 B, retaining sleeve 1 , and receiving member 3 being cooperatively interengaged.

- The instant application claims priority to each of the above-referenced applications. All written material, figures, content and other disclosure in each of the above-referenced applications to the fullest extent permitted are hereby incorporated by reference.
- The present invention relates generally to a lock with a retaining structure, and more specifically, it relates to apparatus, systems and methods for securing at least one structure at least one structure or a portion of a utility service enclosure such as, for example, a watthour meter sealing ring to prevent the separation of two opposing members of the watthour meter sealing ring or, for example, a plurality of structures used with a utility service enclosure, or for example, a watthour meter socket ring to prevent the separation of two opposing members of the watthour meter socket box ring, or used to seal, for example, a trucking, shipping, an airline or other transportation or security container.
- In the electric utility industry, for example, a locking apparatus or seal is useful to secure access panels of enclosures containing electrical or metering equipment. Such a locking apparatus or seal also ideally includes tamper-evident features to indicate unwanted tampering with the seal or attempts to access a secured electrical meter box or the like.
- 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.
- 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 in other industries as well.
- An example of one previously known 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.
- Various designs and uses for watthour meters are also well known, and all such designs and uses are incorporated by reference 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 various 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. A plunger type lock is typically used that is adapted to hold the ends of the sealing ring together. However, the lock is typically separate from the sealing ring before installation. This type of lock also has to be in the “unlocked” position prior to installation; this results in operator inconvenience due to the need for having to handle multiple components simultaneously. When the sealing ring is removed from the meter box, the lock will separate from the apertures or confines of the sealing ring, thus forcing the ring installer to once again handle multiple components simultaneously when the sealing ring is to be reinstalled on a meter box. Moreover, sometimes a key is required to reengage the lock.
- In an attempt to overcome some of these shortcomings, there are various locks that can be installed on ring-type meter socket boxes. Some of these locks can be locked without the use of a key or describe other locking features. Several examples of patents which disclose attempts to solve some of the above problems are set forth as follows.
- U.S. Pat. No. 6,684,670 to Agbay et al., entitled “Lock assembly with self retained barrel lock,” is directed to a security device which comprises a first component having a through first passageway surrounded by an internal first recess, and a second component having a second passageway surrounded by an internal second recess. The first and second components are configured for assembly in a mating relationship with the first and second passageways in communication with each other and in coaxial alignment. A lock has a barrel containing a spring and plunger and carrying radially shiftable locking elements, with the plunger being normally biased by the spring in one direction urging the locking elements into expanded positions protruding radially from the barrel. The barrel is insertable into and releasably retained in an unlocked position in the first passageway with the locking elements expanded radially outwardly into the first recess, and is shiftable by a forwardly applied axial force into a locked position in the second passageway with the locking elements expanded into the second recess. The first recess has a forward surface configured to coact with the locking elements in response to the forwardly applied force to exert a reactionary force urging the locking elements radially inwardly and urging the plunger in the opposite direction to accommodate retraction of the locking elements from the first recess. This reference is incorporated by reference herein.
- U.S. Pat. No. 6,574,999 to Chen, entitled “Padlock with a U-shaped lock casing,” sets forth a padlock which includes a U-shaped lock casing having intercommunicated core receiving space and latch recess, aligned first and second shackle insert holes, and a slide channel communicating the second shackle insert hole with the latch recess. A lock core unit is received in the core receiving space, and includes a latch member extending into the latch recess and rotatable inside the latch recess between locking and unlocking positions. The latch member has an end face formed with a pin hole eccentric to an axis of the lock core unit. A shackle bar extends into the first and second shackle insert holes. A catch member is disposed slidably in the latch recess, and is formed with a pin extending rotatably into the pin hole in the latch member for engaging the latch member. This reference is incorporated by reference herein.
- U.S. Pat. No. 6,467,751 to Korpanty et al., entitled “Inflation valve,” is directed to an inflation valve which has a valve housing having an inner wall, a cylindrical inner chamber terminating in a gas outlet, and a gas inlet bore providing fluid communication between the inner chamber and a pressurized gas source. A piston enclosed in the inner chamber has at one end a head directed toward the gas outlet and at the opposite end a valve actuator connector. The piston further has a gas inlet seal, positioned between the head and the actuator connector, that releasably seals the gas inlet bore from the inner chamber when the piston is in a normal, non-actuated position. A valve actuator connected to the actuator connector operates to pull the piston, thereby moving the gas inlet seal away from the gas inlet bore and putting the inner chamber in fluid communication with the gas inlet bore and pressurized gas source. A regulating spring contacting the piston close to the actuator connector is compressible by the force of pressure exerted by gas contained within the inner chamber and the gas inlet bore and operates to position the piston to control or regulate the outlet pressure. This reference is incorporated by reference herein.
- There remains a need for a retained lock apparatus, system, and method for securing at least one structure or a plurality of structures, to secure a utility service enclosure, such as for example, a meter sealing ring having, for example, ends adapted to mount a lock and a receiving member. There is a need for an apparatus having a retaining sleeve that prevents removal of the lock from the sealing ring after the lock has been disengaged from the lock receiving member or housing. There is a further need for a sleeve adapted to enable the lock to remain in a “preloaded” state until the meter sealing ring is to be installed onto the meter box and the lock is to be engaged into the lock receiving housing.
- 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.
- An object of the present invention is to retain a lock to a portion of a watthour meter sealing ring.
- Another object of the present invention is to retain a lock to a watthour meter sealing ring after the sealing ring has been disengaged from the watthour meter and meter box base, while also allowing the lock to be engaged into a lock receiving member of the sealing ring without the use of a key.
- Another object of the present invention is to provide a lock assembly that can be easily installed onto a watthour meter sealing ring
- Another object of the present invention is to provide a retaining sleeve that can be installed onto an assembled lock.
- Another object of the present invention is to provide a meter sealing ring assembly or combination that can be installed and locked onto a watthour meter box without the need for special tools or keys.
- Another object of the present invention is to provide a meter sealing ring assembly that when unlocked, will allow a lock to be easily positioned for relocking at a later time without the use of a key.
- Another object of the present invention is to provide a retaining sleeve that will retain locking members (which may be cylindrical and/or moveable) of a lock.
- Another object of the present invention is to provide a retaining sleeve that will slide on a lock shaft, allowing locking members (which may be spherical and/or moveable), to expand in a radial direction.
- These and other objects, features, and advantages will become apparent from the drawings, the descriptions given herein, and the appended claims. However, it will be understood that the above-listed objectives and/or advantages are intended only as an aid in quickly understanding aspects of the invention, are not intended to limit the invention in any way, and therefore do not form a comprehensive or restrictive list of objectives, and/or features, and/or advantages. Accordingly, certain example embodiments provide a locking apparatus for securing at least one structure or a portion of utility service enclosure such as, for example, a watthour meter socket ring to prevent the separation of two opposing members of the watthour meter socket box ring, so as to address the needs as described above.
- The general purpose of embodiments of the invention, which will be described subsequently in greater detail, is to secure at least one structure or a plurality of structures, to lock a utility service enclosure, such as for example, a meter sealing ring having ends adapted to mount a lock and a receiving member, and to retain a lock to a portion of a watthour meter sealing ring.
- One example embodiment the invention generally includes at least a lock and a retaining sleeve. The retaining sleeve generally includes at least an aperture, a radial groove, a captive shoulder, and a retaining flange. The lock generally includes at least a head member, a shaft member, multiple spherical (in one example embodiment) locking members, and a cylindrical groove disposed on shaft member. The lock shaft member is adapted to pass through a portion of the sealing ring and receive (permanently, in one example embodiment) the retaining sleeve, thus captivating (or for example, slidably capturing) the lock onto the sealing ring. The captive shoulder disposed on the retaining sleeve is adapted to loosely engage onto the space defined by the cylindrical groove disposed on the shaft member, allowing the retaining sleeve to limitably slide in opposing axial positions. In one example embodiment, the retaining sleeve is preferably adapted to restrict a portion of the lock to facilitate securing the lock portion to the receiving member without the use of a key. For example, in a “preloaded” position, the retaining sleeve is located to the front of the lock shaft (furthest from the lock head), captivating and preventing the spherical locking members from extending radially into the “locked” position. When the tip of the lock shaft is inserted and pressed into the lock receiving member, the retaining sleeve slides toward the rear of the lock shaft (closest to the lock head) and away from the spherical locking members, allowing them to enter into and radially expand into the lock receiving member; this is the “locked” position. When the lock is unlocked and pulled away from the lock receiving member, the retaining sleeve is forced back to the “preloaded” position, retaining the spherical locking members once again.

On the contrary, it is intended to cover all alternatives, modifications, and equivalents included within the spirit of the invention.
- Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, the attached figures illustrate an apparatus for securing a plurality of structures or a portion of a utility service enclosure. For example, in one embodiment, the apparatus is used for securing a watthour meter socket ring so as to prevent the separation of two opposing members of the watthour meter socket box ring. The apparatus may be used for creating a tamper-evident seal by securably connecting a plurality of structures. The apparatus may also be used as a locking assembly with at least one structure as will hereinafter be explained in further detail.
- Referring now to
FIG. 1 , there is shown asecuring sealing ring 2 for a ringed-type meter box (not shown). In order to hold a meter (not shown) in place and prevent its removal from the meter box, both the meter and meter base incorporate a corresponding set of flanges (not shown) that are retained together with an annular,lockable sealing ring 2. Thelockable sealing ring 2 is designed to encase and captivate the corresponding flanges of the meter and base when the ends 9A, 9B of the sealingring 2 are held or connected together. There are different types of lock devices for holding or connecting theends - Now referring to
FIGS. 1-2 , there is shown one example embodiment for securing a plurality of structures with each of the plurality of structures defining an aperture therein.FIG. 2 shows a plurality ofstructures 9 B having apertures ring 2, which may be connected or disconnected, the ring being adapted to mount a meter to a meter box structure (not shown). Each of the first and second ends 9A, 9B of thering 2 definesapertures FIG. 2 , alock 19 and a retainingsleeve 1 is adapted to be installed onto a watthour meterbox sealing ring 2.FIG. 2 shows thelock 19 prior to the lock being retained by retainingsleeve 1. - Referring now to
FIGS. 1-3 , there is shown one example embodiment for securing first and second ends 9A, 9B of ameter sealing ring 2, the meter sealing ring adapted for use in installing a meter to a watthour meter box. As shown in the embodiment ofFIG. 3 , thelock 19 has ahead member 6 and ashank portion 8, which in one example embodiment is a shaft member. Thelock 19 further comprises at least one and preferably twomoveable locking members shaft member 8 is insertable through anaperture 12A formed in thefirst end 9A of the sealingring 2. In this way, thelock 19 may be viewed as being mounted to the first end of the sealing ring. - A retaining
sleeve 1 is adapted to capture the shank portion or, for example,shaft member 8 wherein thelock 19 is retained on thefirst end 9A of the sealingring 2. In an example embodiment, the shank portion may be viewed as being between the first and second ends 9A, 9B of the sealingring 2. - A receiving
member 3 in alternate example embodiment is adapted to secure themoveable locking members shaft member 8 with the first and second ends 9A, 9B of thering 2 held between the receiving member andhead member 6. - In one example embodiment, the shank portion comprises a
shaft member 8 with an outer surface defining acylindrical groove 21. The retaining sleeve preferably has an axial bore adapted to receive at least a portion of theshaft member 8 with the retaining sleeve adapted in surrounding relation with at least a portion of acylindrical groove 21 so as to slidably capture theshaft member 8. However, it will be appreciated that the groove may only extend around a portion of the shaft or be configured like a slot or have another configuration suitable for slidable engagement and capture by the retainingsleeve 1. - As shown in the embodiment of
FIG. 3 thelock 19 generally collectively comprises thehead member 6, theshaft member 8, preferably multiple moveable locking members 4 ideally having a spherical configuration (or cylindrical or other configuration), thecylindrical groove 21 disposed on theshaft member 8, and a biasing structure. The biasing structure is preferably aplunger 5 and aspring 7. - In the example embodiment of
FIG. 3 , the retainingsleeve 1 is generally comprised of anaperture 20, aradial groove 13, a captive shoulder 4, and a retainingflange 16. - When the
plunger 5 is retracted toward thehead 6, as shown inFIG. 2 , the spherical locking members 4 are allowed to retract radially inward, allowing the lock shaft to pass through a circular opening that is slightly larger than thelock shaft 8 diameter; this is the “unlocked position”. - When in the “unlocked” position, the
lock shaft 8, is adapted to pass through anaperture 12 disposed on a sealing ring member 9 and forcibly receive retainingsleeve 1. As the retainingsleeve 1 is engaged closer to thehead member 6, the retainingflange 16 will collapse into the space defined by thecylindrical groove 21 disposed on thelock shaft member 8. This allows the retainingsleeve 1 to freely slide in opposing limiting axial positions, and consequently, captivating the sealing ring member 9 between thelock head 6 and the retainingsleeve 1. - When the
plunger 5 is released, shown inFIG. 5 , thespring 7, which is captivated between thehead 6 and theplunger 5, forces theplunger 5 toward the spherical locking members 4. This causes anedge 14 of theplunger 5 to force the spherical locking members 4 radially outward until the larger diameter of theplunger 5 can pass through the locking members 4; this is the “locked” position. - As the retaining
sleeve 1 is moved toward the front of the lock shaft 8 (furthest from the lock head 6), thegroove wall 17 disposed on thelock shaft 8 interferes with the retainingflange 16, preventing the retainingsleeve 1 from separating from thelock shaft 8. When the retainingsleeve 1 is in this position and theplunger 5 is released, theradial groove 13 captivates the locking members 4 and will not allow theplunger 5 to pass though them and into the “locked” position. This ensures that a constant force is applied to the wall of theradial groove 13 of the retainingmember 1. - When the tip of the
lock shaft 8 is inserted into theaperture 10 of thelock receiving member 3, the retainingsleeve 1 bears against the entry perimeter of receivingmember 3 until the applied force exceeds the resistive force created by the interference between the spherical locking members 4 and thecaptive shoulder 15, allowing the retainingsleeve 1 to slide toward the rear of the lock shaft 8 (closest to the lock head) and away from the spherical locking members 4. This allows thelock shaft 8 to fully enter thelock receiving member 3 until the spherical locking members 4 can expand into the radial groove 11 (“locked” position). When thelock 19 is unlocked and pulled away from thelock receiving member 3, the retainingsleeve 1 is forced back to the “preloaded” position, retaining the spherical locking members 4 once again. - In another example embodiment, the retaining sleeve may also serve as a spacer-like member between a plurality structures, with the retaining sleeve being dimensioned as required to set apart the structures as desired. It may also be made of an insulating material and used as a retaining member and/or insulating member as well as a spacer.
- Another example embodiment of
FIG. 6 comprises acombination 50 of thelock 19, first and second ring ends 9A, 9B, retainingsleeve 1, and receivingmember 3 being cooperatively interengaged. With this configuration, at least a portion (such as the lock and housing or housing and second end of the ring or of the combination is separable, but still interengaged in thecombination 50. - 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.
