Roadside Mailbox System and Method

Abstract

Mailbox system comprising a cylindrical main support shell affixed on one end to an underside of a mailbox and affixed on another end to a ground-based stabilization structure, wherein the main support shell is oriented vertically to enable mail pickup and delivery operations relative to the mailbox and adjustable support structures internal to the main support shell to enable at least one of height adjustment, ground-based stabilization structure adjustments, or mailbox orientation adjustments. The support shell is resistant to impacts and degradation caused by vehicle traffic and environmental conditions such as snow, ice, water, and gravel launched toward the support system, and the impacts of other objects such as gravel, vehicle parts, and road debris launched against the support system at various speeds, such as associated with snowplows, sand trucks, salt trucks.

Description

RELATED APPLICATIONS STATEMENT

[0001] This application claims benefit to Provisional patent application Ser. No. 63 / 779,476 filed Mar. 28, 2025, the entirety of which is incorporated by reference herein.BACKGROUND

[0002] Roadside mailboxes are required in many situations and can be exposed to numerous conditions detrimental to what would be expected to be a normal lifetime. However, weather and roadside conditions can shorten the lifetime of such mailboxes due to impacts from road debris such as gravel and chunks of road material, ice, snow, salt, etc., any of which are typical problems for roadside mailboxes.

[0003] Accordingly, replacing or repairing a conventional roadside mailbox system can become a repetitive and expensive process due to less effective support systems extending from the ground, concrete, and / or paved roadway surfaces to the mailbox support platforms. Such replacements can incur a costly and time-consuming process, and also lead to the interruption of mail delivery service due to the refusal of the postal service to deliver mail to mailboxes not meeting government standards.SUMMARY

[0004] The following presents a simplified summary in order to provide a basic understanding of some novel embodiments described herein. This summary is not an extensive overview, and it is not intended to identify key / critical elements or to delineate the scope thereof. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.

[0005] The disclosed architecture is a roadside mailbox support system. The support system comprises an above-ground support configuration and predominantly a base and / or below-ground anchor configuration. A release mechanism is provided with the below-ground anchor configuration but designed to extend a short length (e.g., 2-6 inches) above the ground (or base) surface for attachment of the above-ground configuration.

[0006] The above-ground configuration also comprises a cylindrical outer (main support) shell having a diameter that can range from about four (4) inches to about eight (8) inches, for example, and a height (or cylinder length) conducive to achieving the roadside mailbox specifications required by the USPS (United States Postal Service) for mail / item delivery and pick-up services. The above-ground cylindrical outer support shell can be a hard plastic tube, such as constructed of polyethylene, PVC (polyvinyl chloride) plastic, or the like, while the inner support post can be a combination of pieces of U-channel post (also referred to herein as “post pieces”).

[0007] The curved outer surface of the outer cover shell is geometrically conducive for deflecting debris such as snow, ice, gravel, and any debris thrown at a high rate of speed by a snowplow or motor vehicle. The curved surface presents a much smaller impact zone than a flat surface, as well as preventing or mitigating debris buildup (e.g., snow and ice build-up) that could accumulate if using a flat-sided geometry such as a square or rectangular shaped shell. Installation of the entire system can be achieved quickly and easily achieved due to the outlined structures.

[0008] The above-ground configuration can also include an inner U-channel support post (e.g., metal, with rust-resistant coating and notched with holes for fixing height adjustment with fasteners), which provides inner strength and support to the mailbox system, and which existing wood and / or plastic mailbox post products lack. The adaptor piece is positioned between the bottom of the mailbox and above the cover shell and inner support post.

[0009] The below-ground anchor configuration includes a support post for additional strength and anchor support, can be thirty-six inches (36″) of the total length of forty-two inches (42″) placed into the ground as the anchor (e.g., below the frost line).

[0010] The U-channel configuration prevents an effect that might otherwise be experienced by heaving of the anchor post system due to temperature and seasonal environmental fluctuations that can have an adverse impact on the ground support system. Accordingly, the U-channel configuration enables the mailbox system to remain upright and level to the road surface, despite continual impact from road debris thrown by snowplows and temperature / seasonal fluctuations.

[0011] The attachment point(s) for the upper inner support post and the lower support post utilizes two fasteners (e.g., bolts) which facilitate a breakaway function, thereby minimizing damage to the mailbox structure, as well as any motor vehicle in the event of a collision.

[0012] The design of the threaded attachment point for the mailbox support base plate (adapter piece) on the inner support post equips the structure with additional strength, as well as an expeditious installation and removal method in the case of any necessary repairs. This also allows for any repairs to be conducted away from the roadside in a safe and comfortable environment. The receiver adapter piece can include a female-threaded mounting piece with mounting holes into which one or more steel bolts (or pins) can be employed to secure the configuration and / or orientation to the first post piece, thereby lending additional strength to the overall mailbox structure to remain in place in an upright position amidst impacts from at least roadside debris and in adverse environmental conditions (e.g. strong winds, debris impacts, etc.).

[0013] In one implementation, the mailbox support base plate can be made of a sufficient strength and non-corroding composite plastic, which will not deteriorate under most, if not all, in-situ conditions, and can withstand many weather conditions.

[0014] Accordingly, in one embodiment, there is disclosed a roadside mailbox system, comprising an above-ground support subsystem comprising a first post piece, a post adapter piece mounted to a top end of the first post piece, a mailbox base plate affixed to a top surface of the post adapter piece, and a mailbox housing mounted to a top surface of the mailbox base plate. An in-ground anchor subsystem is provided which comprises a second post piece, the second post piece having a bottom portion implanted into an in-ground anchor area and a top end connected to a bottom end of the first post piece, to secure the above-ground support subsystem to the in-ground anchor subsystem. A support shell can be installed over the above-ground support subsystem, the support shell and above-ground support subsystem oriented vertically to enable mail pickup and delivery operations relative to the mailbox housing.

[0015] The above-ground support subsystem comprises an adjustment capability which enables at least one of a height adjustment in a vertical plane or a rotational adjustment in a horizontal plane. The first post piece is positioned vertically and internal to the support shell and extends from the post adapter plate to proximate the in-ground anchor area. The roadside mailbox system can further comprise a coupling section between the first post piece and the second post piece, which second post piece is a ground implanted support post, the coupling section enables securement of the above-ground system to the in-ground anchor area. At least one of the support shell or the post adapter piece are affixed to the mailbox base plate.

[0016] The roadside mailbox system can further comprise a breakaway subsystem at the coupling section, which enables the above-ground support subsystem to detach from the in-ground anchor area to mitigate damage to the above-ground support subsystem. The breakaway subsystem enables the above-ground support subsystem to at least one of flex, bend, or detach from the in-ground anchor section in response to an impacting force received against a portion of the support shell.

[0017] The post adaptor piece comprises an alignment portion which threadedly engages the mailbox base plate at an interior receptacle at in the upper end of the first post piece and is secured to the upper end. A top end of the support shell and the post adapter piece both affix to a bottom surface of the mailbox base plate.

[0018] The roadside mailbox system can further comprise a standoff subsystem installed on the first post piece, and which enables adjustment of a standoff distance between the first post piece and an inside surface of the outer shell, along at least one of one or two different vertical locations along the first post piece.

[0019] In another embodiment, there is disclosed a roadside mailbox system, comprising an above-ground support subsystem comprising a first post piece, a post adapter piece mounted to a top end of the first post piece, a mailbox base plate affixed to a top surface of the post adapter piece, and a mailbox housing mounted to a top surface of the mailbox base plate, the above-ground support subsystem comprises an adjustment capability which enables at least one of a height adjustment in a vertical plane or a rotational adjustment in a horizontal plane, wherein the first post piece is positioned vertically and internal to the support shell and extends from the post adapter piece to proximate the in-ground anchor area.

[0020] The roadside mailbox system can further comprise an in-ground anchor subsystem comprising a second post piece, the second post piece having a bottom portion implanted into an in-ground anchor area and a top end connected to a bottom end of the first post piece, to secure the above-ground support subsystem to the in-ground anchor subsystem. The roadside mailbox system can further comprise a support shell installed over the above-ground support subsystem, the support shell and above-ground support subsystem oriented vertically to enable mail pickup and delivery operations relative to the mailbox housing.

[0021] The roadside mailbox system can further comprise a breakaway subsystem which enables the above-ground support subsystem to respond to an impact to the support shell; and, a standoff subsystem installed on the first post piece, and which enables adjustment of a standoff distance between the first post piece and an inside surface of the outer shell, along at least one of one or two different vertical locations along the first post piece.

[0022] The roadside mailbox system can further comprise a coupling section between the first post piece and the second post piece, which second post piece is a ground implanted support post, the coupling section enables securement of the above-ground system to the in-ground anchor area. A breakaway subsystem enables the above-ground support subsystem to at least one of flex, bend, or detach from the in-ground anchor section in response to an impacting force received against a portion of the mailbox system. The post adaptor piece comprises an alignment portion which threadedly engages an interior receptacle in the upper end of the first post piece and is secured to the upper end. The top end of the support shell and the post adapter piece can both affix to a bottom surface of the mailbox base plate.

[0023] In still another disclosed embodiment, there is disclosed a roadside mailbox system, comprising an above-ground support subsystem comprising a first post piece, a post adapter piece mounted to a top end of the first post piece, a mailbox base plate affixed to a top surface of the post adapter piece, and a mailbox housing mounted to a top surface of the mailbox base plate, the above-ground support subsystem comprises an adjustment capability which enables at least one of a height adjustment in a vertical plane or a rotational adjustment in a horizontal plane, wherein the first post piece is positioned vertically and internal to the support shell and extends from the post adapter piece to proximate the in-ground anchor area; further comprising an in-ground anchor subsystem comprising a second post piece, the second post piece having a bottom portion implanted into an in-ground anchor area and a top end connected to a bottom end of the first post piece, to secure the above-ground support subsystem to the in-ground anchor subsystem; further comprising a support shell installed over the above-ground support subsystem, the support shell and above-ground support subsystem oriented vertically to enable mail pickup and delivery operations relative to the mailbox housing; a breakaway subsystem which enables the above-ground support subsystem to at least one of flex, bend, or detach from the in-ground anchor section in response to an impacting force received against a portion of the support shell; a standoff subsystem installed on the first post piece, and which enables adjustment of a standoff distance between the first post piece and an inside surface of the outer shell, along at least one of one or two different vertical locations along the first post piece; and, a coupling section between the first post piece and the second post piece, which second post piece is a ground implanted support post, the coupling section enables securement of the above-ground system to the in-ground anchor area.

[0038] Reference is now made to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the novel embodiments can be practiced without these specific details. In other instances, well known structures and devices are shown in diagram form in order to facilitate a description thereof. The intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the claimed subject matter.

[0039] FIG. 1 illustrates an expanded view of the roadside mailbox system 100 showing an arrangement of various structural components, in accordance with disclosed embodiments. The mailbox system 100 comprises an above-ground support (and adjustment configuration) subsystem 102 and in-ground anchor subsystem 104. The above-ground support subsystem 102 can comprise a first post piece 106 (dashed line border to indicate internal to an outer cover shell 110) and a second post piece 108 (predominantly, the in-ground anchor portion).

[0040] The first post piece 106 (also inner support post 106) and the second post piece 108 (also anchor post piece 108) can overlap at a coupling section 112 (also referred to as “breakaway” section 112) to enable securing the two post support pieces (106 and 108) together at or near (e.g., 2-6, 4-8, inches, etc.) the ground surface. The in-ground anchor section 108 (also, second post piece 108) can also extend a sub-surface portion thereof at a length that can range between four (4) and eighteen (18) inches, for example, as a stable in-ground anchor system.

[0041] Accordingly, if sufficiently impacted by snow during snow removal, vehicles, etc., the above-ground (mailbox support) subsystem 102 (also the above-ground configuration) may “break” away (where the term “break” is intended to include any one or more of flexing, bending, or complete detachment, where “flexing” deforms from an original orientation to a flexed orientation, but then returns back to the original orientation once the impact is over, “bending” deforms from the original orientation to a retained bent orientation, and “breaking” is the complete detachment at the breakaway (coupling) section 112 (e.g., the above-ground subsystem 102 completely detaches from the in-ground anchor post 108).

[0042] These capabilities are provided to minimize or mitigate damage to the above-ground configuration (or subsystem) 102, and yet be suitable for re-mounting of the configuration 102 relative to an anchor area 124 (e.g., solely concrete formed, solely impacted ground soil, etc.) once again for the intended functions of the mailbox system 100. The anchor area 124 can be an assembled base such as with concrete, or can simply be impacted ground into which the in-ground anchor post 108 is implanted to the desired depth.

[0043] The above-ground subsystem 102 can also comprise the cylindrical outer cover shell 110 (also “support shell” or “cover shell”110) having a diameter that can range from about four (4) inches to about eight (8) inches, for example, and a height (or cylinder length) conducive to achieving the roadside mailbox specifications required by the USPS (United States Postal Service) for mail / item delivery and pick-up services.

[0044] The outer cover / support shell 110, when installed over the inner support and adjustment structures (e.g., inner support post 106 and anchor post piece 108), is centered on a vertical axis approximated by a line centered along the lengths of the overall coupling of inner support post 106 and anchor post piece 108. The above-ground cylindrical outer cover shell 110 can be a plastic cylindrical tube or pipe, such as constructed of polyethylene, PVC (polyvinyl chloride) plastic, or the like.

[0045] The curved outer surface of the outer cover shell 110 is geometrically conducive (curved surface) for deflecting debris such as snow, ice, gravel, and any debris thrown at a high rate of speed by a snowplow or motor vehicle, rather than receiving a more direct impact that normally would be received against a flat surface if using a rectangular shell. The curved surface presents a much smaller impact zone than a flat surface, as well as preventing or mitigating debris buildup (e.g., snow and ice build-up) that could accumulate if using the flat-sided geometry such as a square or rectangular shaped shell. Installation of the entire mailbox system 100 can be achieved quickly and easily due to the disclosed features.

[0046] The first post piece (inner support post) 106 can be a U-channel metal post with an anti-rust coating and notched with bolt holes for height adjustment and fastening to the in-ground and compatible with the U-channel post 108, which provides inner strength and support to the mailbox system 102, and which existing wood and / or plastic mailbox post products lack. The inner support post 106 is positioned internal to the outer cover shell 110 and abuts to internal surfaces of the outer shell 110 at one or more points to provide enhanced structural support and vertical alignment to the overall mailbox system 100. The anchor support post 108 allows for the mailbox system structure(s) to be easily installed in a variety of ground applications, including pitched or graded surfaces, without the sacrifice of strength and stability in the overall mailbox structure.

[0047] The inner support post 106 also enables attachment of a mailbox (housing) 116 to the overall support system via a mailbox base plate 113 (of any geometry, dimensions, and attachment features). The base plate 113 affixes to the underside of the mailbox housing 116. A post adapter piece 114 (e.g., a female threaded pipe flange-a receiver portion 117) is then mounted to the underside of the mailbox base plate 113 (of any compatible geometry).

[0048] The upper end 120 of the first post piece 106 can be configured with a section of pipe 115 secured therein to the upper end 120, and compatibly threaded on the upper pipe end (closest the post adapter piece 114) to secure into (or screw into) the threads of the post adapter piece 114 (threaded pipe flange). Thus, installation of the mailbox housing 116 to the above ground subsystem 102 comprises engaging the compatible threads of the pipe 115 to the post adapter piece 114 and tightening the mailbox subsystem (e.g., the mailbox housing 116, mailbox base plate 113, and post adapter piece 114, etc.) to the threads of the pipe 115 of the above ground subsystem 102. The unthreaded portion of the pipe 115 can be secured into the upper end 120 of the inner support post 106 by securely clamping the unthreaded portion of the pipe to prevent rotation of the pipe 115 or drilling holes into the pipe and securing the pipe via fastening of the pipe 115 to the upper end 120. This is more clearly depicted in FIG. 6, showing a pipe flange 606 secured to the base plate 113 and threaded to the compatible pipe 115 secured to the upper end 120 of the first post piece 106.

[0049] The outer shell 110 installs over (surrounds) the inner support post 106 to enable an overall contiguously solid framework for mailbox protection and support. When fully assembled as a single system, the inner support post 106, and anchor support post 108, and in-ground anchor subsystem 104, in general, add enhanced stability to the roadside mailbox system 100 to withstand impacts from road debris, snow, water, gravel, etc.

[0050] The in-ground anchor configuration 104 can include the predominantly subsurface implanted second post piece 108 for additional strength and anchor support, can approximate thirty-six inches (36″) of the total length of a length of forty-two inches (42″) placed into the ground as part of the anchor configuration (e.g., below the frost line).

[0051] The U-channel structural design mitigates movement (e.g., flexure, bending, etc.) of the post pieces (106 and 108, separately or secured together) under any in-situ conditions (e.g., strong winds) thereby providing enhanced stability which may otherwise be experienced by the subsurface heaving of existing mailbox anchor systems due to temperature and seasonal environmental fluctuations that can have an adverse impact on the ground support system. Accordingly, the U-channel configuration enables the mailbox system to remain upright, level, and properly oriented relative to the road surface, despite continual impact from road debris thrown by snowplows and temperature / seasonal fluctuations.

[0052] The coupling section 112 is where the inner support post 106 and the lower support post 108 can be fastened together (e.g., utilizing two fasteners such as nut / bolt sets). The section 112, also referred to as the breakaway section 112, facilitates a release point for disassembly and / or a breakaway function if struck by a vehicle, thereby minimizing damage to the mailbox structure, as well as any motor vehicle in the event of a collision. The section 112 is the location where the inner support post and the ground implanted support post can be secured together by overlapping and fastening together sections of the post pieces (106 and 108).

[0053] In one implementation, either one or both of the mailbox base plate 113 and adapter piece 114 can be made of materials of a sufficient strength such as non-corroding composite plastic, metal(s), etc., which will not deteriorate under most, if not all, in-situ conditions, and can withstand many weather conditions.

[0054] As indicated elsewhere herein, the system 100 can be implanted on / into a solid base anchor area 124, which can be concrete, impacted ground or soil, or other implementation techniques that maintain a substantial vertical deployment of the system 100 under most all debris impacts and environmental conditions (e.g., strong winds, driving rain, etc.) and USPS requirements.

[0055] FIG. 2 illustrates a sketch 200 of an arrangement of the structures and assembly specifications interior to the support shell 110, in addition to adjustment holes, fastener specifications, and dimensional assembly specifications. The footer includes an overlapping footer and post breakaway section 112 where, if an excessive force of impact by a vehicle, for example, is applied to the mailbox structure such as the support shell 110, for example, against the mailbox structure exceeds the strength of the breakaway section 112, the breakaway section 112 breaks such that the remaining support structure and the mailbox experience minimal damage, if at all. The roadside mailbox support system 100, comprises inner support structures such as U-channels which provide strength and support, that current wood or plastic post products lack.

[0056] A lower support post provides additional strength and support, as thirty-six (36) inches of the total forty-two (42) inches total length, for example, can be placed into the ground below the frost line. The U-channel configuration prevents heaving of the support post due to environmental changes, thereby allowing the overall mailbox system to remain upright and level to the road surface, despite continual impacts from road debris thrown by snowplows and temperature fluctuations.

[0057] The attachment points for the upper inner support post and the lower support post employs two bolts that facilitate a breakaway feature, minimizing damage to the mailbox structure as well as any motor vehicle in the event of a collision. The design of the threaded attachment point for the mailbox support plate on the inner support post equips the structure with exceptional strength as well as simple installation and removal method in the case of any necessary repairs. This also enables repairs to be conducted away from the roadside in a safe area.ItemQtyDescription 11Mailbox - United States Postal Service (USPS) approved 28Hardware to mount Mailbox to mailbox support plate(MSP): 1⅝ inch; #8 exterior screw T-20star-drive head. 31PVC material; see FIG. 3 - MSP ¾ in.

[0064] Here, two fastener standoff assemblies 608A and 608B are provided to serve as standoff adjustments of the outer shell 110 relative to placement and orientation of the mailbox 604 (similar to mailbox housing 116), to reduce or eliminate any movement of the mailbox housing 604 and / or outer shell 110 relative to the inner support post.

[0065] The alignment assemblies 608A and 608B (e.g., two carriage bolt fasteners) can provide a standoff distance between the inner post 106 and the inside (inner) surface of the outer shell 110, at two different vertical locations along the inner post 106. Thus, installation of the outer shell 110 can be adjusted such that the rounded head of a first carriage bolt assembly 608A contacts the inner surface of the outer shell 110, in one installation, and a second carriage bolt assembly 608B performs the same function opposite (approximately 180 degrees in the opposite direction) to the inner side of the outer shell 110. These assemblies 608A and 608B enable the outer shell 110 to be securely installed and centered about the support post and (inner support post 106), using one or more locking nuts to adjust the standoff distance from the desired standoff point (defined as the contact point of the curved head of the carriage bolt to the curved interior surface of the outer shell 110).

[0066] FIG. 7 illustrates an opposing side view 700 of the mailbox system 600 of FIG. 6. The opposing view 700 shows the mailbox 604 mounted on the mailbox base plate 113 and support post adapter piece 114 (e.g., circular), in accordance with an embodiment. As previously described, the top end 120 of the inner support post 106 is ultimately affixed to the adapter piece 114 by threaded attachment (partially viewable here) and to the upper end 120, by nut-bolt combinations.

[0067] FIG. 8 illustrates a frontal view 800 of the mailbox system 600 of FIG. 6, and system 700 of FIG. 7. The frontal view 800 shows the mailbox housing 602 mounted on the mailbox base plate 113 and support post adapter piece 114 (e.g., circular), in accordance with an embodiment. As previously described, the top end 120 of the inner support post 106 is affixed to the adapter piece 114 by threaded attachment (partially viewable here) and to the top end by nut-bolt combinations. The frontal view 800 enables a side view 802 of the support post assembly, which shows fastener locations to fasten the one or more support posts together to achieve the desired mailbox height. The carriage bolt assemblies 802 function to center the outer support shell 110 on a mailbox center line or point to a vertical axis of the outer shell, to account for any dissimilar alignment between the two U-channel posts of second post piece 108 and first post piece 106, when secured together.

[0068] FIG. 9 illustrates the side view 900 of the mailbox system 602, but with the outer shell cover 110 installed and covering the support post adapter piece 114 and other internal structures from environmental conditions.

[0069] FIG. 10 illustrates the frontal view 1000 (similar to view 800) of the mailbox system 602, and with the outer shell cover 110 now installed and covering the support post adapter piece 114 and other internal structures / assemblies from environmental conditions.

The outer cover 1302 is installed over the interior post pieces and centered on the vertical axis derived by the combination of one or more of the post pieces, such as, the (inner) first post piece, and (inner) second post piece.

[0071] What has been described above includes examples of the disclosed architecture. It is, of course, not possible to describe every conceivable combination of components and / or methodologies, but one of ordinary skill in the art may recognize that many further combinations and permutations are possible. Accordingly, the novel architecture is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims. Furthermore, to the extent that the term “includes” is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim.

RELATED APPLICATIONS STATEMENT

[0001] This application claims benefit to Provisional patent application Ser. No. 63 / 779,476 filed Mar. 28, 2025, the entirety of which is incorporated by reference herein.BACKGROUND

[0002] Roadside mailboxes are required in many situations and can be exposed to numerous conditions detrimental to what would be expected to be a normal lifetime. However, weather and roadside conditions can shorten the lifetime of such mailboxes due to impacts from road debris such as gravel and chunks of road material, ice, snow, salt, etc., any of which are typical problems for roadside mailboxes.

[0003] Accordingly, replacing or repairing a conventional roadside mailbox system can become a repetitive and expensive process due to less effective support systems extending from the ground, concrete, and / or paved roadway surfaces to the mailbox support platforms. Such replacements can incur a costly and time-consuming process, and also lead to the interruption of mail delivery service due to the refusal of the postal service to deliver mail to mailboxes not meeting government standards.SUMMARY

[0004] The following presents a simplified summary in order to provide a basic understanding of some novel embodiments described herein. This summary is not an extensive overview, and it is not intended to identify key / critical elements or to delineate the scope thereof. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.

[0005] The disclosed architecture is a roadside mailbox support system. The support system comprises an above-ground support configuration and predominantly a base and / or below-ground anchor configuration. A release mechanism is provided with the below-ground anchor configuration but designed to extend a short length (e.g., 2-6 inches) above the ground (or base) surface for attachment of the above-ground configuration.

[0006] The above-ground configuration also comprises a cylindrical outer (main support) shell having a diameter that can range from about four (4) inches to about eight (8) inches, for example, and a height (or cylinder length) conducive to achieving the roadside mailbox specifications required by the USPS (United States Postal Service) for mail / item delivery and pick-up services. The above-ground cylindrical outer support shell can be a hard plastic tube, such as constructed of polyethylene, PVC (polyvinyl chloride) plastic, or the like, while the inner support post can be a combination of pieces of U-channel post (also referred to herein as “post pieces”).

[0007] The curved outer surface of the outer cover shell is geometrically conducive for deflecting debris such as snow, ice, gravel, and any debris thrown at a high rate of speed by a snowplow or motor vehicle. The curved surface presents a much smaller impact zone than a flat surface, as well as preventing or mitigating debris buildup (e.g., snow and ice build-up) that could accumulate if using a flat-sided geometry such as a square or rectangular shaped shell. Installation of the entire system can be achieved quickly and easily achieved due to the outlined structures.

[0008] The above-ground configuration can also include an inner U-channel support post (e.g., metal, with rust-resistant coating and notched with holes for fixing height adjustment with fasteners), which provides inner strength and support to the mailbox system, and which existing wood and / or plastic mailbox post products lack. The adaptor piece is positioned between the bottom of the mailbox and above the cover shell and inner support post.

[0009] The below-ground anchor configuration includes a support post for additional strength and anchor support, can be thirty-six inches (36″) of the total length of forty-two inches (42″) placed into the ground as the anchor (e.g., below the frost line).

[0010] The U-channel configuration prevents an effect that might otherwise be experienced by heaving of the anchor post system due to temperature and seasonal environmental fluctuations that can have an adverse impact on the ground support system. Accordingly, the U-channel configuration enables the mailbox system to remain upright and level to the road surface, despite continual impact from road debris thrown by snowplows and temperature / seasonal fluctuations.

[0011] The attachment point(s) for the upper inner support post and the lower support post utilizes two fasteners (e.g., bolts) which facilitate a breakaway function, thereby minimizing damage to the mailbox structure, as well as any motor vehicle in the event of a collision.

[0012] The design of the threaded attachment point for the mailbox support base plate (adapter piece) on the inner support post equips the structure with additional strength, as well as an expeditious installation and removal method in the case of any necessary repairs. This also allows for any repairs to be conducted away from the roadside in a safe and comfortable environment. The receiver adapter piece can include a female-threaded mounting piece with mounting holes into which one or more steel bolts (or pins) can be employed to secure the configuration and / or orientation to the first post piece, thereby lending additional strength to the overall mailbox structure to remain in place in an upright position amidst impacts from at least roadside debris and in adverse environmental conditions (e.g. strong winds, debris impacts, etc.).

[0013] In one implementation, the mailbox support base plate can be made of a sufficient strength and non-corroding composite plastic, which will not deteriorate under most, if not all, in-situ conditions, and can withstand many weather conditions.

[0014] Accordingly, in one embodiment, there is disclosed a roadside mailbox system, comprising an above-ground support subsystem comprising a first post piece, a post adapter piece mounted to a top end of the first post piece, a mailbox base plate affixed to a top surface of the post adapter piece, and a mailbox housing mounted to a top surface of the mailbox base plate. An in-ground anchor subsystem is provided which comprises a second post piece, the second post piece having a bottom portion implanted into an in-ground anchor area and a top end connected to a bottom end of the first post piece, to secure the above-ground support subsystem to the in-ground anchor subsystem. A support shell can be installed over the above-ground support subsystem, the support shell and above-ground support subsystem oriented vertically to enable mail pickup and delivery operations relative to the mailbox housing.

[0015] The above-ground support subsystem comprises an adjustment capability which enables at least one of a height adjustment in a vertical plane or a rotational adjustment in a horizontal plane. The first post piece is positioned vertically and internal to the support shell and extends from the post adapter plate to proximate the in-ground anchor area. The roadside mailbox system can further comprise a coupling section between the first post piece and the second post piece, which second post piece is a ground implanted support post, the coupling section enables securement of the above-ground system to the in-ground anchor area. At least one of the support shell or the post adapter piece are affixed to the mailbox base plate.

[0016] The roadside mailbox system can further comprise a breakaway subsystem at the coupling section, which enables the above-ground support subsystem to detach from the in-ground anchor area to mitigate damage to the above-ground support subsystem. The breakaway subsystem enables the above-ground support subsystem to at least one of flex, bend, or detach from the in-ground anchor section in response to an impacting force received against a portion of the support shell.

[0017] The post adaptor piece comprises an alignment portion which threadedly engages the mailbox base plate at an interior receptacle at in the upper end of the first post piece and is secured to the upper end. A top end of the support shell and the post adapter piece both affix to a bottom surface of the mailbox base plate.

[0018] The roadside mailbox system can further comprise a standoff subsystem installed on the first post piece, and which enables adjustment of a standoff distance between the first post piece and an inside surface of the outer shell, along at least one of one or two different vertical locations along the first post piece.

[0019] In another embodiment, there is disclosed a roadside mailbox system, comprising an above-ground support subsystem comprising a first post piece, a post adapter piece mounted to a top end of the first post piece, a mailbox base plate affixed to a top surface of the post adapter piece, and a mailbox housing mounted to a top surface of the mailbox base plate, the above-ground support subsystem comprises an adjustment capability which enables at least one of a height adjustment in a vertical plane or a rotational adjustment in a horizontal plane, wherein the first post piece is positioned vertically and internal to the support shell and extends from the post adapter piece to proximate the in-ground anchor area.

[0020] The roadside mailbox system can further comprise an in-ground anchor subsystem comprising a second post piece, the second post piece having a bottom portion implanted into an in-ground anchor area and a top end connected to a bottom end of the first post piece, to secure the above-ground support subsystem to the in-ground anchor subsystem. The roadside mailbox system can further comprise a support shell installed over the above-ground support subsystem, the support shell and above-ground support subsystem oriented vertically to enable mail pickup and delivery operations relative to the mailbox housing.

[0021] The roadside mailbox system can further comprise a breakaway subsystem which enables the above-ground support subsystem to respond to an impact to the support shell; and, a standoff subsystem installed on the first post piece, and which enables adjustment of a standoff distance between the first post piece and an inside surface of the outer shell, along at least one of one or two different vertical locations along the first post piece.

[0022] The roadside mailbox system can further comprise a coupling section between the first post piece and the second post piece, which second post piece is a ground implanted support post, the coupling section enables securement of the above-ground system to the in-ground anchor area. A breakaway subsystem enables the above-ground support subsystem to at least one of flex, bend, or detach from the in-ground anchor section in response to an impacting force received against a portion of the mailbox system. The post adaptor piece comprises an alignment portion which threadedly engages an interior receptacle in the upper end of the first post piece and is secured to the upper end. The top end of the support shell and the post adapter piece can both affix to a bottom surface of the mailbox base plate.

[0023] In still another disclosed embodiment, there is disclosed a roadside mailbox system, comprising an above-ground support subsystem comprising a first post piece, a post adapter piece mounted to a top end of the first post piece, a mailbox base plate affixed to a top surface of the post adapter piece, and a mailbox housing mounted to a top surface of the mailbox base plate, the above-ground support subsystem comprises an adjustment capability which enables at least one of a height adjustment in a vertical plane or a rotational adjustment in a horizontal plane, wherein the first post piece is positioned vertically and internal to the support shell and extends from the post adapter piece to proximate the in-ground anchor area; further comprising an in-ground anchor subsystem comprising a second post piece, the second post piece having a bottom portion implanted into an in-ground anchor area and a top end connected to a bottom end of the first post piece, to secure the above-ground support subsystem to the in-ground anchor subsystem; further comprising a support shell installed over the above-ground support subsystem, the support shell and above-ground support subsystem oriented vertically to enable mail pickup and delivery operations relative to the mailbox housing; a breakaway subsystem which enables the above-ground support subsystem to at least one of flex, bend, or detach from the in-ground anchor section in response to an impacting force received against a portion of the support shell; a standoff subsystem installed on the first post piece, and which enables adjustment of a standoff distance between the first post piece and an inside surface of the outer shell, along at least one of one or two different vertical locations along the first post piece; and, a coupling section between the first post piece and the second post piece, which second post piece is a ground implanted support post, the coupling section enables securement of the above-ground system to the in-ground anchor area.

[0038] Reference is now made to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the novel embodiments can be practiced without these specific details. In other instances, well known structures and devices are shown in diagram form in order to facilitate a description thereof. The intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the claimed subject matter.

[0039] FIG. 1 illustrates an expanded view of the roadside mailbox system 100 showing an arrangement of various structural components, in accordance with disclosed embodiments. The mailbox system 100 comprises an above-ground support (and adjustment configuration) subsystem 102 and in-ground anchor subsystem 104. The above-ground support subsystem 102 can comprise a first post piece 106 (dashed line border to indicate internal to an outer cover shell 110) and a second post piece 108 (predominantly, the in-ground anchor portion).

[0040] The first post piece 106 (also inner support post 106) and the second post piece 108 (also anchor post piece 108) can overlap at a coupling section 112 (also referred to as “breakaway” section 112) to enable securing the two post support pieces (106 and 108) together at or near (e.g., 2-6, 4-8, inches, etc.) the ground surface. The in-ground anchor section 108 (also, second post piece 108) can also extend a sub-surface portion thereof at a length that can range between four (4) and eighteen (18) inches, for example, as a stable in-ground anchor system.

[0041] Accordingly, if sufficiently impacted by snow during snow removal, vehicles, etc., the above-ground (mailbox support) subsystem 102 (also the above-ground configuration) may “break” away (where the term “break” is intended to include any one or more of flexing, bending, or complete detachment, where “flexing” deforms from an original orientation to a flexed orientation, but then returns back to the original orientation once the impact is over, “bending” deforms from the original orientation to a retained bent orientation, and “breaking” is the complete detachment at the breakaway (coupling) section 112 (e.g., the above-ground subsystem 102 completely detaches from the in-ground anchor post 108).

[0042] These capabilities are provided to minimize or mitigate damage to the above-ground configuration (or subsystem) 102, and yet be suitable for re-mounting of the configuration 102 relative to an anchor area 124 (e.g., solely concrete formed, solely impacted ground soil, etc.) once again for the intended functions of the mailbox system 100. The anchor area 124 can be an assembled base such as with concrete, or can simply be impacted ground into which the in-ground anchor post 108 is implanted to the desired depth.

[0043] The above-ground subsystem 102 can also comprise the cylindrical outer cover shell 110 (also “support shell” or “cover shell”110) having a diameter that can range from about four (4) inches to about eight (8) inches, for example, and a height (or cylinder length) conducive to achieving the roadside mailbox specifications required by the USPS (United States Postal Service) for mail / item delivery and pick-up services.

[0044] The outer cover / support shell 110, when installed over the inner support and adjustment structures (e.g., inner support post 106 and anchor post piece 108), is centered on a vertical axis approximated by a line centered along the lengths of the overall coupling of inner support post 106 and anchor post piece 108. The above-ground cylindrical outer cover shell 110 can be a plastic cylindrical tube or pipe, such as constructed of polyethylene, PVC (polyvinyl chloride) plastic, or the like.

[0045] The curved outer surface of the outer cover shell 110 is geometrically conducive (curved surface) for deflecting debris such as snow, ice, gravel, and any debris thrown at a high rate of speed by a snowplow or motor vehicle, rather than receiving a more direct impact that normally would be received against a flat surface if using a rectangular shell. The curved surface presents a much smaller impact zone than a flat surface, as well as preventing or mitigating debris buildup (e.g., snow and ice build-up) that could accumulate if using the flat-sided geometry such as a square or rectangular shaped shell. Installation of the entire mailbox system 100 can be achieved quickly and easily due to the disclosed features.

[0046] The first post piece (inner support post) 106 can be a U-channel metal post with an anti-rust coating and notched with bolt holes for height adjustment and fastening to the in-ground and compatible with the U-channel post 108, which provides inner strength and support to the mailbox system 102, and which existing wood and / or plastic mailbox post products lack. The inner support post 106 is positioned internal to the outer cover shell 110 and abuts to internal surfaces of the outer shell 110 at one or more points to provide enhanced structural support and vertical alignment to the overall mailbox system 100. The anchor support post 108 allows for the mailbox system structure(s) to be easily installed in a variety of ground applications, including pitched or graded surfaces, without the sacrifice of strength and stability in the overall mailbox structure.

[0047] The inner support post 106 also enables attachment of a mailbox (housing) 116 to the overall support system via a mailbox base plate 113 (of any geometry, dimensions, and attachment features). The base plate 113 affixes to the underside of the mailbox housing 116. A post adapter piece 114 (e.g., a female threaded pipe flange-a receiver portion 117) is then mounted to the underside of the mailbox base plate 113 (of any compatible geometry).

[0048] The upper end 120 of the first post piece 106 can be configured with a section of pipe 115 secured therein to the upper end 120, and compatibly threaded on the upper pipe end (closest the post adapter piece 114) to secure into (or screw into) the threads of the post adapter piece 114 (threaded pipe flange). Thus, installation of the mailbox housing 116 to the above ground subsystem 102 comprises engaging the compatible threads of the pipe 115 to the post adapter piece 114 and tightening the mailbox subsystem (e.g., the mailbox housing 116, mailbox base plate 113, and post adapter piece 114, etc.) to the threads of the pipe 115 of the above ground subsystem 102. The unthreaded portion of the pipe 115 can be secured into the upper end 120 of the inner support post 106 by securely clamping the unthreaded portion of the pipe to prevent rotation of the pipe 115 or drilling holes into the pipe and securing the pipe via fastening of the pipe 115 to the upper end 120. This is more clearly depicted in FIG. 6, showing a pipe flange 606 secured to the base plate 113 and threaded to the compatible pipe 115 secured to the upper end 120 of the first post piece 106.

[0049] The outer shell 110 installs over (surrounds) the inner support post 106 to enable an overall contiguously solid framework for mailbox protection and support. When fully assembled as a single system, the inner support post 106, and anchor support post 108, and in-ground anchor subsystem 104, in general, add enhanced stability to the roadside mailbox system 100 to withstand impacts from road debris, snow, water, gravel, etc.

[0050] The in-ground anchor configuration 104 can include the predominantly subsurface implanted second post piece 108 for additional strength and anchor support, can approximate thirty-six inches (36″) of the total length of a length of forty-two inches (42″) placed into the ground as part of the anchor configuration (e.g., below the frost line).

[0051] The U-channel structural design mitigates movement (e.g., flexure, bending, etc.) of the post pieces (106 and 108, separately or secured together) under any in-situ conditions (e.g., strong winds) thereby providing enhanced stability which may otherwise be experienced by the subsurface heaving of existing mailbox anchor systems due to temperature and seasonal environmental fluctuations that can have an adverse impact on the ground support system. Accordingly, the U-channel configuration enables the mailbox system to remain upright, level, and properly oriented relative to the road surface, despite continual impact from road debris thrown by snowplows and temperature / seasonal fluctuations.

[0052] The coupling section 112 is where the inner support post 106 and the lower support post 108 can be fastened together (e.g., utilizing two fasteners such as nut / bolt sets). The section 112, also referred to as the breakaway section 112, facilitates a release point for disassembly and / or a breakaway function if struck by a vehicle, thereby minimizing damage to the mailbox structure, as well as any motor vehicle in the event of a collision. The section 112 is the location where the inner support post and the ground implanted support post can be secured together by overlapping and fastening together sections of the post pieces (106 and 108).

[0053] In one implementation, either one or both of the mailbox base plate 113 and adapter piece 114 can be made of materials of a sufficient strength such as non-corroding composite plastic, metal(s), etc., which will not deteriorate under most, if not all, in-situ conditions, and can withstand many weather conditions.

[0054] As indicated elsewhere herein, the system 100 can be implanted on / into a solid base anchor area 124, which can be concrete, impacted ground or soil, or other implementation techniques that maintain a substantial vertical deployment of the system 100 under most all debris impacts and environmental conditions (e.g., strong winds, driving rain, etc.) and USPS requirements.

[0055] FIG. 2 illustrates a sketch 200 of an arrangement of the structures and assembly specifications interior to the support shell 110, in addition to adjustment holes, fastener specifications, and dimensional assembly specifications. The footer includes an overlapping footer and post breakaway section 112 where, if an excessive force of impact by a vehicle, for example, is applied to the mailbox structure such as the support shell 110, for example, against the mailbox structure exceeds the strength of the breakaway section 112, the breakaway section 112 breaks such that the remaining support structure and the mailbox experience minimal damage, if at all. The roadside mailbox support system 100, comprises inner support structures such as U-channels which provide strength and support, that current wood or plastic post products lack.

[0056] A lower support post provides additional strength and support, as thirty-six (36) inches of the total forty-two (42) inches total length, for example, can be placed into the ground below the frost line. The U-channel configuration prevents heaving of the support post due to environmental changes, thereby allowing the overall mailbox system to remain upright and level to the road surface, despite continual impacts from road debris thrown by snowplows and temperature fluctuations.

[0057] The attachment points for the upper inner support post and the lower support post employs two bolts that facilitate a breakaway feature, minimizing damage to the mailbox structure as well as any motor vehicle in the event of a collision. The design of the threaded attachment point for the mailbox support plate on the inner support post equips the structure with exceptional strength as well as simple installation and removal method in the case of any necessary repairs. This also enables repairs to be conducted away from the roadside in a safe area.ItemQtyDescription 11Mailbox - United States Postal Service (USPS) approved 28Hardware to mount Mailbox to mailbox support plate(MSP): 1⅝ inch; #8 exterior screw T-20star-drive head. 31PVC material; see FIG. 3 - MSP ¾ in.

At 514, the protective cover 110 is attached to the underside of the mailbox base plate 113 using mounting clip hardware.

[0063] FIG. 6 illustrates a side view 600 of a mailbox system 602. The mailbox system 602 includes a mailbox (housing) 604 mounted on a mailbox base plate 113 and support post adapter piece 606 (e.g., circular), in accordance with an embodiment. The top end 120 of the inner support post 106 is affixed to the adapter piece 606 (similar to piece 114) by threaded attachments to the upper end 120 of the inner support post 106 by nut-bolt combinations.

[0064] Here, two fastener standoff assemblies 608A and 608B are provided to serve as standoff adjustments of the outer shell 110 relative to placement and orientation of the mailbox 604 (similar to mailbox housing 116), to reduce or eliminate any movement of the mailbox housing 604 and / or outer shell 110 relative to the inner support post.

[0065] The alignment assemblies 608A and 608B (e.g., two carriage bolt fasteners) can provide a standoff distance between the inner post 106 and the inside (inner) surface of the outer shell 110, at two different vertical locations along the inner post 106. Thus, installation of the outer shell 110 can be adjusted such that the rounded head of a first carriage bolt assembly 608A contacts the inner surface of the outer shell 110, in one installation, and a second carriage bolt assembly 608B performs the same function opposite (approximately 180 degrees in the opposite direction) to the inner side of the outer shell 110. These assemblies 608A and 608B enable the outer shell 110 to be securely installed and centered about the support post and (inner support post 106), using one or more locking nuts to adjust the standoff distance from the desired standoff point (defined as the contact point of the curved head of the carriage bolt to the curved interior surface of the outer shell 110).
