Temporary Fence Panel Joiners

Abstract

The fence panel coupler (1) includes a first coupling member (1a) having a first connector portion (2) and a second connector portion (4), each having openings (18, 24) for receiving a first fence post (74) and a second fence post (76). The second coupling member (1b) includes a third connector portion and a fourth connector portion, also with openings for receiving the first and second fence posts. The first and second coupling members are applied to the fence post in a first insertion direction and moved together in a second direction perpendicular to the insertion direction to a closed configuration. Integral locking elements (60a, 60b) lock the first and second coupling members together in the closed configuration. The connector portions cooperate to surround the fence post, preventing removal of the fence post coupler from the fence post.

Description

[Technical Field]

[0001] The present disclosure relates to temporary fence panel couplers, and more particularly to two-part fence couplers that do not require additional fasteners. [Background technology]

[0002] Temporary fence panels are commonly used for safety and security purposes to form non-permanent barriers around areas such as construction sites and outdoor events. Temporary, movable fence panels for such applications typically consist of an outer frame formed from one or more tubular metal poles. Each fence panel includes at least two vertical posts and a mesh panel supported within the outer frame. The fence panels are sized so that they can be manually moved into position, and a series of fence panels can be assembled to form the desired barrier.

[0003] A weighted base or foot is associated with adjacent pairs of fence panels, including a socket for receiving and supporting each fence panel's post. The weighted base secures the fence panels and provides stability. Fence post couplers are also used to secure adjacent vertical fence posts together, providing a more solid connection and preventing the fence from easily coming apart. The outer frame is generally formed as a continuous loop, and the inner mesh panel is permanently connected to the frame. Therefore, it is not possible to slide a circular connector onto the fence post. Instead, fence post couplers generally comprise a clamping arrangement including rigid metal clamp plates located on either side of the fence post and secured together with threaded fasteners. A bolt extends through a central hole in the clamp plate in the gap between the fence posts and is secured with a corresponding nut.

[0004] To apply this coupling, clamping plates must be held in position on either side of the fence post while the threaded fasteners are engaged and tightened. The location of the fasteners means that the tightening tool must operate within the confined space between the fence posts. Holding the clamping plates in place and tightening them in this manner is a difficult manual task, often requiring two people. Multiple coupling components must be obtained and distributed prior to assembly and are easily dropped or lost during assembly, especially in adverse weather conditions. Additionally, threaded nut and bolt fasteners tend to loosen over time and can be easily tampered with or removed using commonly available tools.

[0005] Therefore, current temporary fence panel connectors are time-consuming and labor-intensive to apply. They are also unsecure, prone to tampering, and heavy and cumbersome to distribute, store, and transport. Furthermore, each fence connector must be applied with a tool, and the metal parts can rust over time. Summary of the Invention [Problem to be solved by the invention]

[0006] It would therefore be desirable to provide an improved temporary fence coupler that addresses the above-mentioned problems and / or provides improvements generally. [Means for solving the problem]

[0007] In accordance with the present disclosure, there is provided a fence panel joiner and method for joining fence panels as set forth in the accompanying claims.

[0008] In an aspect of the disclosure, a fence panel coupler is provided, the fence panel coupler comprising: a first coupling member including first and second connector portions, each having an opening for receiving a respective one of a first fence post and a second fence post; and a second coupling member including third and fourth connector portions, each having an opening for receiving a respective one of the first and second fence posts. The first and second coupling members are movable together into an engaged, closed configuration and include an integral connector element that connects the first and second coupling members together in the closed configuration to prevent removal of the fence post coupler from the fence post in use. The connector holds the engaged coupling members together in the closed configuration.

[0009] The connector element may be a locking element that locks the first and second coupling members together in the closed configuration.

[0010] In the closed configuration, the fence post is received within the first connector portion and the second connector portion, the first coupling member prevents the second coupling member from being released from the fence post in a first direction, and the second coupling member prevents the first coupling member from being released from the fence post in an opposite second direction.

[0011] The term fence post is used herein to generally refer to a structural element of a fence panel and can refer to a cylindrical post, but is not limited to such a configuration. The two connecting members include integral locking elements and can therefore be secured to the fence panel without the need for further fastening or the need for tools.

[0012] The locking elements can be any elements that mechanically engage to prevent vertical separation, i.e., separation along the length of the fence post, and / or lateral separation, i.e., separation perpendicular to the length of the fence post. Locking elements can include and be configured to prevent, for example, arrowhead locking tabs or interlocking dovetail elements. The use of integral locking elements eliminates the need for separate fasteners, such as nut and bolt fasteners or cable ties, to secure the coupling members. The coupler is thus a two-part coupler that requires no additional parts and can be mated manually without the need for tools.

[0013] The closed configuration refers to the standard, non-flexible configuration of the connector portion, where the opening dimension is greater than zero but less than the diameter of the fence post, so that the fence post cannot be received within the opening without enlarging the opening for the connector portion to be inserted into the fence post.

[0014] The connector portions can each include a resilient, flexible element reconfigurable to an enlarged configuration to enlarge the respective openings of the connector portions to receive the respective fence posts. In particular, the first and second connector portions of the first coupling member and the third and fourth connector portions of the second coupling member each include a resilient, flexible element. The resilient, flexible element can be any element that is an integral part of the connector portions and that can be moved by flexing to enlarge the opening of the respective connector portion.

[0015] Each connector portion includes an internal receiving section or cavity for receiving a fence post, with an opening providing access for the fence post to be inserted into the receiving section. The receiving section can be circular in the closed configuration with a first diameter corresponding to the diameter of the fence post, and the opening has a width. The diameter of the receiving section is greater than the width of the opening. Each receiving section has a circumference that increases when the respective coupling portion is flexed to the expanded configuration.

[0016] The openings of the first and second connector portions are configured to receive the first and second fence posts, respectively, when the first coupling member is applied to the fence post in a first insertion direction, and the openings of the third and fourth post connector portions are configured to receive the first and second fence posts, respectively, when the second coupling member is applied to opposite sides of the fence post in a second insertion direction opposite the first insertion direction. The unitary connector is configured to connect when the first and second coupling members are moved into engagement in a closing direction perpendicular to the first and second insertion directions. In use, the insertion direction is configured along an insertion axis perpendicular to the fence post, and the closing direction is in the same direction as the longitudinal axis of the fence post.

[0017] The connector portions of the first and second coupling members are C-shaped with opposing ends defining an opening therebetween and an interior cavity configured to receive a fence post. The flexible element of each connector portion includes a flexible arm formed by a free end of the respective C-shaped connector portion. The free end is a distal end of the C-shaped connector, and the opposite proximal end is fixed so as to be integrally formed with the body or bridge section of the coupling member.

[0018] The C-shaped connector portion connects to the fence post in an annular snap-fit ​​configuration, where the connector portion flexes and expands to extend its circumference around the post, and then returns to its original dimensions after the fence post is accommodated by the circumferential strain that holds the coupling member in place on the fence post. This snap-fit ​​configuration allows each coupling member to be applied individually, without the need for support, and is held on the fence post while other coupling members are applied and the coupling members are closed together. The snap-fit ​​engagement also allows the connector to be easily rotated relative to the fence post, allowing the relative orientation of the fence panels to be easily adjusted to modify the fence line. The relative rotation of the coupler and fence post also allows the coupler to function as a hinge, allowing fence panels to be connected on only one side, operating as a doorway, if desired.

[0019] The first and second coupling members can include retaining elements that engage with the flexible arms of the corresponding coupling members to restrain the flexible arms and prevent outward deflection when in the closed configuration. The retaining elements can comprise, for example, raised wall sections or tabs located outwardly of the flexible elements, or can comprise locking tabs that engage with corresponding slots in the distal ends of the flexible arms.

[0020] The coupling member can slide along the fence post when the fence post is received within the connector portion of the coupling member, and the first coupling member and the second coupling member can slide along the fence post, toward each other, into the closed configuration.

[0021] The flexible arms of each connector portion may be reconfigurable between a clamping configuration in which the opening has a first width and an expanded configuration in which the opening has a second width and is biased into the clamping configuration, which is the normal position to which the flexible arms are biased.

[0022] The flexible arms of each connector portion move to an enlarged configuration when the opening of the connector portion is pressed against the fence post. The connector portions have chamfered leading edges that interact with the curved surface of the fence post to create a lateral pushing force that enlarges the opening. Each flexible finger is configured to be biased against a corresponding fence post when the fence post is received within the connector portion. The degree of biasing force is determined in part by the normal, unenlarged inner diameter of the receiving section relative to the diameter of the fence post. The biasing force is sufficient to allow the coupling member to self-grippingly grip the fence post and also allows a person to manually slide the coupling member along the fence post.

[0023] The first and second connector portions of the first coupling member are interconnected by a first bridge section, and the third and fourth connector portions of the second coupling member are interconnected by a second bridge section, and the locking elements of the first and second coupling members are located on the first and second bridge sections, respectively.

[0024] The coupling members can be a pair of generally identical components. Each coupling member has an outer surface, an inner surface, a leading edge, and a trailing edge. In use, the couplers are positioned at spaced locations along the fence post, with their inner surfaces facing each other along the closure axis and their openings facing in opposite directions along the insertion axis. The trailing edge of the first closure member is aligned with the leading edge of the second closure member, and the leading edge of the first closure member is aligned with the trailing edge of the second closure member, i.e., the coupling members are rotated 180° relative to each other along their longitudinal axes.

[0025] Each connecting member is a single piece of integrally molded components. The connecting members may be formed from a thermoplastic material.

[0026] The first coupling member can include a first closure element and a second closure element, and the second coupling member can include a third closure element and a fourth closure element, where the first closure element and the second closure element are configured to close the openings of the third and fourth coupling portions when the first and second coupling members are connected in the closed configuration, and the third and fourth closure elements are configured to close the openings of the first and second connector portions. The closure elements protrude inward (i.e., away from the inner surface) of the connector portions and are diametrically opposite the openings so that they fit within the corresponding openings of the opposing coupling member in the closed configuration. The closure elements bridge the openings to create a continuous, annular connection around the fence post. The coupling members thereby combine to enclose both fence posts in a handcuff configuration.

[0027] The first and second closure members can be integrally formed parts of the first and second connector portions, and the third and fourth closure members are integrally formed parts of the third and fourth connector portions. In the closed configuration, the first and third connector portions combine to form a first annular connector that, in use, surrounds a first fence post, and the second and fourth connector portions combine to form a second annular connector that, in use, surrounds a second fence post.

[0028] The locking elements can be arrowhead-type connectors each extending from an inner surface of a respective coupling member and each including a flexible shaft and a tapered locking head. The flexible shaft can be a stem, an upstanding wall, or any other upstanding flexible support element. When the coupling members are moved to the closed configuration, the locking elements flex away from each other due to the wedged engagement of the angled surfaces of the locking heads and close into an interlocked configuration when the locking heads pass each other, where the locking surfaces of the locking elements abut against each other to prevent release.

[0029] In use, the first and second coupling members are movable into a closed configuration along a closure axis parallel to the longitudinal axis of the fence post, the coupling members are inserted onto the fence post along an insertion axis perpendicular to the closure axis, and the locking elements are interlocked to prevent separation at the closure axis.

[0030] The first coupler and the second coupler can include a second interlocking element configured to lock together when the coupling members are in the closed configuration and prevent separation along the insertion axis. The second locking element can include a dovetail formation formed on an inner surface of the coupling members.

[0031] The coupling members include side walls that cooperate to create a continuous enclosure in the closed configuration. The integral locking element is enclosed within the fence panel coupler in the closed configuration and cannot be manually accessed. At least one of the coupling members includes an aperture configured to receive a tool to release the locking element and enable it to be separated from the coupling member.

[0032] In another aspect of the present disclosure, there is provided a fence panel joining system comprising the fence panel coupler described above and a release tool configured to be inserted into the aperture of the joining member. Locking elements are positioned relative to the aperture so that they are engaged by the release tool upon insertion, causing the locking elements to separate. In this manner, the coupler can only be released using a dedicated tool, preventing unauthorized removal.

[0033] The release tool can include a shaft or stem having a longitudinal axis and first and second transverse dimensions (e.g., width and thickness) perpendicular to the longitudinal axis, the second transverse dimension being greater than the first transverse dimension. The stem is inserted in a first orientation in which the locking elements are separated by the first transverse dimension, and the stem is rotatable to a second orientation in which the locking elements are separated by the second transverse dimension. The stem is rotated using a handle. The aperture is formed to allow the stem to be inserted only in the first orientation.

[0034] The stem can include a locking tab that is received through the aperture when the stem is inserted in a first orientation and that engages one of the coupling members to prevent release of the stem from the aperture when the stem is in a second orientation, allowing a release tool to lift the coupling member to separate the fence coupler. The aperture is formed to allow insertion of the stem only in the first orientation and to prevent release of the stem in the second orientation due to interference of the locking element.

[0035] A tool is inserted into an aperture (keyhole) in one of the coupling members. The coupling member includes an angled element located on its inner surface near the aperture that is configured to be engaged by the locking element when the stem is rotated to the second configuration, moving the stem axially further into the coupler and applying an axial separating axial force against the locking element. Because both coupling members are identical, they both have apertures and either can be selected so that the coupler can be released from either.

[0036] In another aspect of the disclosure, a method of joining fence panels is provided, the method including the steps of providing a fence coupler as described above; connecting a first coupling member to a first side of a first fence post and a second fence post in a first insertion direction; connecting a second coupling member to an opposite second side of the first fence post and the second fence post in an opposite second insertion direction at a location spaced from the first coupling member relative to the length of the fence post; and moving the first and second coupling members to a closed configuration by sliding at least one of the coupling members toward the other coupling member in a closing direction along the first and second fence posts.

[0037] The method can further include removing the fence coupler by inserting a tool into the aperture of the fence coupler and operating the tool to separate and release interlocked locking elements of the first and second coupling members, separating the first and second coupling members in a direction opposite the closing direction when the locking elements are released, and removing the first and second coupling members from the fence post in a direction opposite the first and second insertion directions, respectively. The method can include using the tool to lift one of the coupling members from the other coupling member.

[0038] In another aspect of the disclosure, a fence panel coupler is provided, comprising a first coupling member including first and second connector portions, each having an opening for receiving one of a first fence post and a second fence post, respectively. The second coupling member includes third and fourth connector portions, each having an opening for receiving one of the first and second fence posts and a resilient, flexible element reconfigurable to an enlarged configuration for enlarging the respective opening for receiving the respective fence post. Both the first and second coupling members are movable to a closed configuration and include an integral locking element that locks the first and second coupling members together in the closed configuration in use to prevent removal of the fence post from the fence post.

[0039] Another aspect of the present disclosure provides a two-piece coupler including a first coupling member and a second coupling member. The coupling members are individually secured to a pair of fence posts and are each configured to connect to one another when secured to the fence posts. When connected, the first coupling member and the second coupling member cooperate to form a pair of annular connectors that surround the fence posts and prevent both coupling members from being released from the fence posts. The coupling members are secured to the fence posts in a snap-fit ​​configuration. The first coupling member and the second coupling member preferably include integrally formed locking elements that cooperate to prevent separation of the first coupling member and the second coupling member.

[0040] Another aspect of the present disclosure provides a fence panel coupler including a first coupling member and a second coupling member. The first coupling member and the second coupling member are connectable and combine to form, in use, a coupler having first and second annular connector portions that surround the posts. The first coupling member includes first and second connector portions, each having an opening for receiving one of the first and second fence posts, respectively. The second coupling member is configured to close the first and second openings of the first coupling member to form the annular connector portions.

[0041] The second coupling member can include a third connector portion and a fourth connector portion, each having an opening for receiving a respective one of the first and second fence posts. The first and second coupling members are connected in a closed configuration, where the first and third coupling members combine to create the first annular connector portion and the second and fourth coupling members combine to form the second annular connector portion.

[0042] The present disclosure will now be described, by way of example only, with reference to the accompanying exemplary figures. [Brief explanation of the drawings]

[0044] The following description presents exemplary embodiments and, together with the drawings, serves to explain the principles of the present disclosure. The scope of the present disclosure is not intended to be limited to the exact details of the embodiments or to the exact adherence to all method steps. Variations will be apparent to those skilled in the art and are considered to be included in the present description. Terms for features used in this specification should be given a broad interpretation to encompass equivalent functions and features. In some cases, several alternative terms (synonyms) are provided for structural features, but such terms are not intended to be exhaustive.

[0045] Descriptive terms should also be given the broadest possible interpretation. For example, as used herein, the term "comprising" means "consisting at least in part of," and therefore interpretation of each expression herein containing the term "comprising" indicates that features other than those preceded by that term may be present. Related terms, such as "comprising and comprises," should be interpreted similarly. Directional terms, such as "vertical," "horizontal," "top," "bottom," "upper," and "lower," are generally relative terms that may be used for convenient description with reference to examples and are not intended to be ultimately limiting, where equivalent functionality may be achieved using alternative dimensions and / or directions.

[0046] The descriptions herein refer to embodiments using specific combinations of constituent steps or features. However, it is contemplated that further combinations or cross-combinations of compatible steps or features between embodiments are possible. The description of multiple features with respect to any particular embodiment does not imply that such features are intricately linked, and isolated features can function independently of other features and need not necessarily be implemented as a complete combination.

[0047] Referring to FIG. 1, fence panel coupler assembly 1 includes a pair of couplers formed as a single-piece molded plastic component. The couplers include a first coupler 1a and a second coupler 1b. Couplers 1a and 1b are identical components, and the following description of first coupler 1a is also applicable to second coupler 1b. Coupler 1a includes a first connector portion 2, a second connector portion 4, and a bridge section 6. Bridge section 6 interconnects first connector portion 2 and second connector portion 4. First connector portion 2 is integrally formed with and connected to a first side of bridge section 6. Coupler 1a has a leading edge 8 and a trailing edge 10. Coupler 1a has an insertion axis AA extending from front to rear, perpendicular to the length of coupler 1a. The first connector 2 is substantially C-shaped with a first end 12 connected to and integrally formed with the bridge section 6, and a second end 14 defining a curved, flexible arm projecting from the bridge section 6. The C-shaped body of the first connector 2 has a circular interior cavity 16 defined therein. An opening 18 to the C-shaped first connector portion 2 is defined at the front edge 8 of the first connector portion 2, defining the opening to the cavity 16. The flexible fingers 14 of the first connector 2 are configured to flex outward from the opposite end 12 of the connector 2 to enlarge the opening 18. The fingers 14 are resilient and biased to return to their original configuration when any deflecting force is removed. The second connector portion 4 is located on the opposite side of the bridge section 6 and has a mirror image configuration similar to the first connector portion 2. The second connector portion 4 has a first end 20 connected to and integrally formed with the bridge 6, and an opposite second end 22 defining a resiliently flexible finger section. The second connector portion 4 is also C-shaped and has an opening 24 defined between the first end 20 and the second end 22 defined between its opposite distal ends 26, 28. The opening 24 provides access to an interior cavity 30 defined within the C-shaped second connector portion 4.The first connector portion 2 and the second connector portion 4 are of the same size and each have an inner diameter D configured to receive a fence post of circular cross section.

[0048] Connector 1 includes a base 31 including a planar outer surface 33 and an inner surface 32. A plurality of integrally molded upstanding walls extend upwardly from inner surface 32. First connector portion 2 and second connector portion 4 include upstanding inner and outer walls 34, 36 interconnected by a series of reinforcing ribs 38. Inner and outer walls 34, 36 and reinforcing ribs 38 extend from the inner surface to an upper edge 40 having a height H1 from the outer surface.

[0049] The first connector portion 2 and the second connector portion 4 each include a curved closure element 42 located at a rear edge that is elevated relative to the height of the inner and outer walls 34, 36. Referring to the first connector portion 2, the closure element 42 is located diametrically opposite the opening 18. The closure element 42 extends upward from the upper edges 40 of the inner and outer walls 34, 36 by an additional height H1, such that the rear of the first connector portion 2 has a total height H2 that is double the height H1. The angular length of the closure element 42 is equal to the angular length of the opening 18, and the opening 18 and the closure element 42 each extend approximately 45° around the circumference of the first connector portion 2. The closure element 42 is hollow for weight reduction and open at its upper end, thus including a drainage aperture at its base to prevent it from filling with rainwater during use. The closure elements 42 each include an inner end surface 44 located adjacent the bridge 6 and an opposite outer end surface 46. An upstanding positioning tab 49 projects from the outer end surface 46 of the closure element 42. The positioning tab 49 is centered between the inner wall 34 and the outer wall 36 and is stepped vertically below the height of the closure element 42. The distal ends of the flexible arms 14, 22 each include a corresponding slot 51 for receiving a corresponding positioning tab 49 of the second coupler 1b, as described in more detail below.

[0050] The closure element 42 of the second connector part 4 has a similar shape and configuration to the closure element 42 of the first connector part 2 in a mirror image configuration on the opposite side of the bridge 6, and the closure element 42 corresponds in angular length to the opening 24 of the second connector part 4. The closure element 42 is configured to be received within and close the openings 18, 24 of the second coupler 1b.

[0051] The bridge section 6 includes a first positioning element 46 and a second positioning element 48. The first positioning element 46 and the second positioning element 48 are integrally molded and protrude from the inner surface 32. The first positioning element 46 and the second positioning element 48 are laterally aligned and spaced apart in the insertion direction. The first positioning element 46 is disposed toward the rear of the bridge section 6. The first positioning element 46 includes upstanding side walls 50 disposed longitudinally across the bridge section 6, perpendicular to the insertion axis AA. Dovetail portions 52 extend forward from the side walls and taper outward from the side walls 50 to wider forward edges. The dovetail portions 52 are formed by the upstanding walls and have a hollow interior. The side walls 50 include vertical reinforcing ribs located on their rear sides to increase the strength of the side walls 50. The second positioning element 48 is configured on the forward side of the bridge section 6.

[0052] The second positioning element 48 is configured to receive the first positioning element 46 of the second coupler 1b. The second positioning element 48 includes a peripheral wall 54 that forms an enclosure having an internal shape corresponding to the shape of the first positioning element 46. The enclosure includes a side channel section 56 corresponding in shape to the side wall 50 and a dovetail section 58 corresponding in shape to the dovetail portion 52. The side channel section 56 extends longitudinally along the bridge section 6, and the dovetail section extends rearward from the side channel section 56 toward the first positioning element 46 and tapers outwardly rearward. The second positioning element 48 has a height H1, and the outermost wall of the side channel 56 forms a forward wall for the bridge section. An additional wall is provided at the rear edge of the bridge section to surround the bridge section 6. The first positioning element 46 has a height greater than H1, so that it extends beyond the upper edge 40 of the coupler 1a.

[0053] The locking member 60 is positioned between the first positioning element 46 and the second positioning element 48. As shown in FIG. 2 , the locking member 60 consists of an arrowhead-shaped locking tab with an upstanding wall 62 extending from the inner surface 32 and positioned longitudinally along the bridge section, perpendicular to the insertion axis AA. A tapered, wedge-shaped locking head 64 is positioned at the distal end of the wall 62 and slopes downward and outward from the distal end. The locking head 64 includes a lower locking surface 65 positioned perpendicular to the wall 62. The wall has a height H1 that is flush with the upper edge 40 of the peripheral wall of the coupler 1a, and the locking head is positioned above the wall 62, with the lower locking surface 65 positioned at a height H1 that is flush with the upper end of the wall 62. A laterally extending channel 66 and a stepped rectangular recess 67 are formed in the front edge of the upper surface. The rectangular recess 67 is formed with a length that exceeds its depth along the insertion axis. A key slot 68 is formed in the base 31 on the front side of the locking member 60. The key slot 68 is configured directly below the locking head 64. A sloped guide surface 70 is located adjacent the front edge of the key slot 68. An opening 72 is formed in the rear of the second positioning element 48. The opening 72 aligns with the recess 67 of the locking member 60 and partially receives the guide surface 70, with a portion of it extending into the positioning element 48.

[0054] Referring to FIG. 3 , fence panel couplers 1 a, 1 b are used in pairs to secure adjacent fence panels having respective first and second fence posts 74, 76. The fence posts 74, 76 are arranged parallel to one another and each have a length with a longitudinal axis. The longitudinal axis of each post is generally vertically oriented, and references herein to movement in the vertical axis are relative terms that refer to movement along the longitudinal axes of the posts 74, 76. The first coupler 1 a and the second coupler 1 b are arranged such that the first coupler 1 a is located on a first side of the fence posts 74, 76 and the second coupler 1 b is located on the other side of the fence posts 74, 76. During a first assembly stage, the first coupler 1 a is arranged to align the first and second connector portions 2, 4 with the fence posts 74, 76, respectively, with the leading edge of the first coupler 1 a facing the posts 74, 76. The outer surface 33 of the first coupler 1a faces downward, and the inner surface 32 faces upward. The first coupler 1a is moved in a first insertion direction A to engage the posts 74, 76. The first connector portion 2 is inserted onto each post 74 by forcing the opening 18 of the connector portion 2 against the post 74 in the insertion direction A. The diameter of the post 74 corresponds to the diameter of the cavity 16 in the first connector portion 2. Initially, the connector portion 2 is in a neutral, contracted configuration, and the opening 18 is narrower than the diameter of the post 74; therefore, the connector portion 2 is not easily inserted onto the post 74.

[0055] Continued application of pressure in the insertion direction A causes the resilient flexible arms 14 to begin to deflect outwardly to an expanded configuration, which enlarges the opening 18 to receive the post 74. When the post 74 is received within the connector portion 2, the resilient arms 14 return to a contracted configuration and grip the post 74. The connector portion 2 is formed to have a close tolerance fit, or even an interference fit, with the post, so that the flexible arms 14 remain in closed, biased clamping engagement with the post 74. The thickness of the flexible arms 14 and the material of the couplers 1 a, 1 b are selected so that the couplers 1 a, 1 b can reliably be manually pressured against the posts 74, 76 without excessive force or the need for tools. Once the first connector portion 2 is inserted onto the first post 74, the second connector portion 4 is inserted onto the second post 76 in a manner similar to the first connector portion. After the first connector portion is inserted onto the first post, coupler 1a can be rotated about first post 74 to move second connector portion 4 into engagement with second post 76. It will be appreciated that the above assembly order is not essential and second connector portion 4 can be applied first, or first and second connector portions 2, 4 can be pressed into engagement and inserted onto posts 74, 76 simultaneously.

[0056] When the first connector portion 2 and the second connector portion 4 are fastened into position on the posts 74, 76, they are securely connected to the posts 74, 76 so that they are self-supporting and can be released without coming off the posts. At this stage, the fence panels are connected and held together by the first coupler 1a. However, the first coupler 1a can easily be removed from the fence posts 74, 76 by reversing the process described above and pulling it off the posts 74, 76.

[0057] In a second assembly step, the second coupler 1b is moved from the opposite side to engage with the fence posts 74, 76. The second coupler 1b is placed on top of the first coupler 1a in an opposite orientation, with the outer surface 33 facing upward and the inner surface 32 facing downward toward the first coupler 1a. The inner surfaces 32 of the first coupler 1a and second coupler 1b therefore face toward each other. The second coupler 1b is engaged with the fence posts 74, 76 at a vertically spaced position above the first coupler 1a. The second coupler 1b is connected to the fence posts 74, 76 in the same manner as the first coupler 1a, and the connector portions 2, 4 are expanded by the deflection of the elastic arms 14, 22, widening the openings 18, 24 so that the connector portions 2, 4 are fastened onto the posts 74, 76 in a push-fit configuration.

[0058] When the second coupler 1b is secured to the posts 74, 76, the first coupler 1a and the second coupler 1b are moved together by sliding one or both of the couplers 1a, 1b vertically toward each other along the posts 74, 76. As the couplers 1a, 1b are moved together into the coupled assembly, the locking members 60 of each coupler 1a, 1b align and engage with each other, vertically locking the couplers together, as shown in FIG. 4. In this configuration, the closure member 42 of the first coupler 1a is aligned with and received within the openings 18, 24 of the second coupler 1b, and the closure member 42 of the second coupler 1b is aligned with and received within the openings 18, 24 of the first coupler 1a. In this manner, the openings 18, 24 of each coupler are closed, and the connector portions 2, 4 of each coupler 1a, 1b cooperate to form a ring-shaped connector that completely surrounds the fence posts 74, 76 in a handcuff configuration. In this configuration, with openings 18, 24 closed and posts 74, 76 surrounded by the coupling assembly, the coupling assembly 1 cannot be pulled away from the posts 74, 76 in either direction.

[0059] Separation of couplers 1 a, 1 b along the insertion axis is prevented by the interlocking dovetail configuration of first positioning element 46 and second positioning element 48. The first positioning element 46 of first coupler 1 a aligns with and is received within the periphery of the second positioning element 48 of second coupler 1 b when couplers 1 a, 1 b are moved vertically together. Similarly, the first positioning element 46 of second coupler 1 b aligns with and is received within the corresponding second positioning element 48 of first coupler 1 a. The interlocking dovetail configurations of the respective pairs of first positioning elements 46 and second positioning elements 48 together align couplers 1 a, 1 b with one another and prevent separation of couplers 1 a, 1 b from posts 74, 76 in either direction along insertion axis AA. At the same time, the positioning tabs 49 of the first coupler 1 a are received in corresponding slots 51 at the distal ends of the flexible arms 14, 22 of the second coupler 1 b, and the positioning tabs 49 of the second coupler 1 b are received in corresponding slots 51 at the distal ends of the flexible arms 14, 22 of the first coupler 1 a. The positioning tabs 49, located at the distal ends of the flexible arms 14, 22, restrain them laterally, preventing any outward deflection of the flexible arms 14, 22 that might enlarge the openings 18, 24, so that the connecting portions 2, 4 of the first coupler 1 a and second coupler 1 b form a rigid ring around the fence spots 74, 76.

[0060] As shown in FIG. 5, couplers 1a and 1b are configured so that locking member 60a of first coupler 1a and locking member 60b of second coupler 1b are aligned and extend toward each other. Each locking head 64a and 64b is wedge-shaped and includes an angled lead surface 80a and 80b, respectively. When couplers 1a and 1b are moved together, the lead surfaces 80a and 80b engage, and as the two locking members 60a and 60b continue to move toward each other, the angled pushing action of the two locking heads 64a and 64b deflects the locking members 60a and 60b away from each other along insertion axis AA. The locking members 60a and 60b are resilient and biased toward a normal vertical position. When the locking heads 64a and 64b reach a position where they pass each other, they each return to their original upright position. The lower locking surfaces 65a, 65b abut one another, creating a mechanical interlock that prevents vertical separation of the locking members 60a, 60b, thereby securing the couplers 1a, 1b together to create a coupled assembly. The uppermost second coupler 1b, and vice versa, covers and encloses the internal structure of the first coupler 1a. The locking member 64 is thus surrounded and encapsulated by the coupler assembly and cannot be accessed after the coupler assembly is secured. When the couplers 1a, 1b are assembled, the posts are completely enclosed by the connecting portions, and the locking members 60a, 60b cannot be accessed to separate the couplers 1a, 1b, thereby preventing unauthorized removal of the coupler assembly.

[0061] Referring to FIG. 6, a removal tool 82 is provided for separating and removing the coupler assembly. The removal tool 82 includes an elongated handle 84 with a cylindrical barrel 85 and a key 86 protruding from the center of the handle 84. The key 86 includes a stem 88 extending from the barrel 85 in a direction perpendicular to the longitudinal axis of the handle 84. A locking tab 90 protrudes perpendicularly from the stem 88 in a direction parallel to the longitudinal axis of the handle 84. As shown in FIG. 7, the stem 88 has a rectangular cross-section having a width w and a thickness t, where the width w is greater than the depth t. The stem 88 has a front surface 91 and a chamfered lower edge 92 that tapers inward from the front surface 91 toward the distal end of the stem 88. The locking tab 90 is L-shaped with a shaft 96 extending laterally from the stem 88, and a finger 98 is located at the distal end of the shaft 96 and extends forward from the shaft 96 perpendicular to the front surface of the stem 88.

[0062] Referring to FIG. 1 , the key slot 68 is L-shaped and configured to receive the key 86. The L-shaped key slot 68 ensures that the key can only be inserted in a single orientation. The key slot 68 is configured so that the stem 88 of the key 86 is laterally aligned with the recess 67 in the insertion direction. A semicircular guide 93 protrudes from the outer surface 32 of each coupler 1a, 1b and is configured to receive and position the barrel section 85 of the handle 84 to ensure proper alignment of the key 86. The width w of the stem 88 corresponds to the width of the recess 67 of the locking members 60a, 60b. The key 86 is inserted vertically into the key slot 68. The width w of the stem 88 is oriented parallel to the locking member 60b of the uppermost second coupler 1b. The distal end of the key 86 is received within the recess 67 of the locking member 60a of the first coupler 1a. The chamfered lower edge 92 engages the sloped inner surface of the recess 67, creating a lateral reaction force that initially deflects the first locking member 60a outward from the second locking member 60b when the stem 88 of the key 86 is positioned between the locking head 64a of the first locking member 60a and the wall 62b of the second locking member 60b in the first unlocked position. In this first unlocked position, the stem 88 separates the locking head 64a of the first locking member 60a from the second locking member 60b by a distance equivalent to the thickness t of the stem 88. The locking tab 90 remains aligned with the key slot 68.

[0063] As shown in FIGS. 8 and 9, the handle 84 is rotated 90 degrees to rotate the key 86 to the second, unlocked position. In this position, the stem 88 separates the locking head 64a of the first locking member 60a from the second locking member 60b by a distance corresponding to the width w of the stem 88, which is greater than the thickness t. This further deflects the first locking member 60a away from the second locking member 60b. The width w is selected so that, in the second, unlocked position, the locking heads 64a, 64b can separate and vertically pass each other. As shown in FIG. 2, an inclined guide surface 70 is positioned adjacent the key slot 68. The guide surface has a curved shape that corresponds to the arc of rotation of the locking tab 90 and increases in height from a first end adjacent the key slot 68 to an opposite, second end. As the key 86 is rotated between the first and second unlocked positions, the locking tab 90 moves across the surface of the sloped guide surface 70 from the first end to the second end. This moves the stem 88 axially further into the coupling assembly, causing the stem 88 to exert an axial force on the locking member 60 of the opposing coupler in addition to the lateral separation force exerted between the locking members 60 a, 60 b. This force is sufficient to move the locking surfaces 65 a, 65 b axially past each other, disengaging and creating an initial separation of the couplers 1 a, 1 b at the closure axis.

[0064] In the second locking position, the locking tab 90 is rotated to a position where it is not aligned with the key slot 68. Referring again to FIG. 9, the locking tab 90 engages the inner surface of the second coupler 1b. In this position, the key 86 cannot be retracted from the key slot 68 without rotating. Lifting the removal tool 82 upward with the handle 84 causes the locking tab 90 to lift the second coupler 1b, separating the couplers 1a and 1b. The removal tool 82 is required to have a specific geometrically shaped configuration. A recess is located at the second end of the sloped guide surface to position the locking tab as it rotates 90 and travels over the sloped end, and to hold the locking tab 90 in the second, unlocked configuration while the handle is used to lift the coupler.

[0065] The first coupler 1a and the second coupler 1b are identical and both include a key slot 68. Thus, a single generic component is supplied to the construction site, and pairs of the same generic component, i.e., pairs of couplers 1, are provided at each coupling location. The couplers 1 can be applied in any order and can each be oriented to be the upper coupler 1b or the lower coupler 1a. The couplers 1 can be applied individually and are self-supporting once inserted onto the fence post, i.e., no person needs to hold the first coupler 1a while obtaining and applying the second coupler 1b. Furthermore, couplers 1a and 1b can be easily applied by hand, requiring only one person to do so. The coupler 1, therefore, greatly simplifies assembly; it is lightweight, cost-effective, and quick to apply, reducing the labor required. Furthermore, the coupler assembly cannot be removed without custom tools, and therefore does not require any additional fastening, locking, or lashing, making it significantly safer than prior art couplers.

[0066] In a further embodiment, as shown in FIG. 10 , connector portions 1 a, 1 b include an interference member 92 configured to limit deflection of coupler 1 along the longitudinal axis. Interference member 92 includes an upstanding wall 94 extending vertically from upper edges 40 of first coupling portion 2 and second coupling portion 4. Wall 94 is disposed on connector portions 2, 4 between inner and outer walls adjacent bridge 6. Wall 94 each includes a circumferential wall section and a radially extending rib. A recess 96 is formed in each connector portion 2, 4 adjacent wall 94 and configured to receive a corresponding interference member 92 of the other coupling portion 1 b. Additional interference members can be located at other circumferential locations around connector portions 2, 4. Interference member 92 and recess 96 are configured such that interference member 92 is vertically received within recess 96 in a tight fit. Interference member 92 is axially aligned with the recess, with the walls and ribs parallel to the inner walls of recess 94. If coupling members 1 a, 1 b are pried apart at their ends while connected by a bridge by connector 60, the ends will flex relative to bridge 6. This will cause axial misalignment between interference member 92 and recess 94. Interference member 92 will flex into contact with the inner walls of recess 94, and the mechanical interference and frictional engagement between the two parts will prevent or limit vertical separation of the ends of coupling members 1 a, 1 b, limiting the separation and flexing forces applied to connector 60.

[0067] 11-13, a removal tool 182 is provided for separating coupling members 100a, 100b and disengaging coupler assembly 101 from the fence. Removal tool 182 includes an elongated handle 184 and a key 186 protruding from handle 184. Key 186 includes a stem 188 extending from handle 184 in a direction substantially perpendicular to the longitudinal axis of handle 184. Pusher element 187 extends from stem 188. Pusher element 187 has a width and a depth, the width being greater than the depth. Stem 188 has a front face 191 and a chamfered lower edge 192 that tapers inward from front face 191 toward the distal end of stem 188.

[0068] The handle 184 is substantially L-shaped with a distal end 183 configured to be grasped by a user and a proximal end 185 connected to the key 186. Such a shape spaces the distal end 183 of the handle 184 away from the key 186, providing space for the user's hand on the handle 184 and providing a moment arm that can facilitate rotation of the key 186. The axis of the removal tool 182 is located at the proximal end 185 of the handle 184. In this manner, the handle 184 can be confined to one side of the fence panel during use. This can make it easier for a user to install or remove the fence panel coupler, as no part of the handle 184 should need to pass through the fence. Furthermore, the handle 184 is compact and lightweight.

[0069] The removal tool 182 includes a stepped interface portion 189. The stepped interface portion 189 is configured to engage with a rib structure 169 disposed around the aperture 168 of the coupling member 100a. By providing such engagement, the removal tool 182 can be securely positioned relative to the coupling member 100a when the key 186 is within the aperture 168. This can reduce the risk of damage to the key 186 due to stress applied to the handle 184 that is transmitted by the key 186 to the coupling member 100a. The stepped interface portion 189 provides an alternative path for stress transmitted from the handle 184 to the coupling member 100a. In particular, stress applied in a direction other than rotation about the axis of rotation of the removal tool 182 can risk damaging the delicate structure of the key 186. Such stress may be applied by pushing downward or pulling upward on the handle 184 when the key 186 is inserted into the aperture 168 or when rotating the removal tool 182 about the longitudinal axis of the elongated handle 184.

[0070] In use, the pusher element 187 is configured to be rotated by a user operating the removal tool 182 after the key 186 is inserted into the aperture 168 of the coupling member 100a. When inserted into the aperture 168, the pusher element 187 is positioned between the integral connectors 60a, 60b of the coupling members 100a, 100b, and thus the depth of the pusher element 187 is positioned between the integral connectors 60a, 60b of the coupling members 100a, 100b. When rotated by a user operating the removal tool 182, the pusher element 187 is positioned between the integral connectors 60a, 60b of the coupling members 100a, 100b, and thus the width of the pusher element 187 is positioned between the integral connectors 60a, 60b of the coupling members. The width of the pusher element 187 is greater than the depth of the pusher element 187, and after being rotated, the pusher element 187 occupies a greater distance between the integral connectors 60a, 60b of the coupling members 100a, 100b. In that case, when the fence panel coupler is in the closed configuration, the integral connectors 60a, 60b are positioned at a distance from one another that is greater than the depth but less than the width of the pusher element 187, and when the key 186 is inserted through the aperture 168 and rotated, at least one of the integral connectors 60a, 60b can flex, i.e., bend, to accommodate the width of the pusher element 187. The removal tool 182 and the integral connectors 60a, 60b of the fence panel coupler assembly 101 are configured to cooperate such that when the integral connectors 60a or 60b of the coupling elements 100a or 100b are bent by the pushing element 187, the first coupling member 100a and the second coupling member 100b can be disengaged from one another.

[0071] FIG. 12 shows the fence panel coupler assembly 101 with the removal tool 182 in a first orientation. In use, the key 186 of the removal tool 182 is inserted into the aperture 168 of the coupling member 100a of the fence panel coupler assembly 101, as shown in FIG. 12. The aperture 168 is sized so that the key 186 can only be inserted into the aperture 168 when the removal tool 182 is in the first orientation. When in the first orientation, the removal tool 182 is oriented such that the handle 184 is positioned substantially perpendicular to the longitudinal axis of the fence panel coupler 101a. If the fence panels are parallel and adjacent so that the fence is substantially straight, the handle 184 can be positioned substantially perpendicular to the fence when the removal tool 182 is in the first orientation.

[0072] To uncouple the first coupling member 100a and the second coupling member 100b of the fence panel coupler assembly 101 and release the fence panel coupler assembly 101, disconnecting the first and second fence panels, the removal tool 182 is rotated at an acute angle to a second orientation. Because the fence panel coupler assembly 101 is positioned between the fence posts during use, a 90° rotation of the handle 184 of the removal tool 182 may not be possible or easy. On the other hand, a small rotation angle may not provide adequate leverage for the pushing element 187 to bend the integral connectors 60a, 60b of one of the coupling members 100a, 100b, disengaging the integral connectors 60a, 60b and uncoupling the coupling members 100a, 100b. Therefore, the acute angle may be approximately 45° or greater. 13 shows a cross section of the fence panel coupler assembly 101 with the removal tool 182 in a second orientation. The first coupling member 100a receives the key 186 of the removal tool 182 through the aperture 168 or key slot of the coupling member 100a. The push-in element 187 of the key 186 of the removal tool 182 interacts with the integral connectors 60a, 60b of the coupling members 100a, 100b. In particular, the push-in element 187 of the key 186 of the removal tool 182 applies a force to the integral connector 60b of the second coupling member 100b, bending it away from the key 186 and, therefore, away from the integral connector 60a of the first coupling member 100a. Thus, when the removal tool 182 is in the second orientation, the first and second coupling members 60a, 60b are unlocked from one another and can be disconnected so as not to occupy the closed configuration. In this manner, the removal tool 182 unlocks the coupling members 100a, 100b.

[0073] 14 , coupling member 100a includes a first connector portion 102, a second connector portion 104, and a bridge section 106. Bridge section 106 is disposed between first connector portion 102 and second connector portion 104 to connect first connector portion 102 and second connector portion 104. First connector portion 102 is integrally formed with bridge section 106 and connected to a first side thereof. Second connector portion 104 is integrally formed with bridge section 106 and connected to a second side thereof.

[0074] The coupling member 100a has a leading edge 108 and a trailing edge 110. The first connector portion 102 is substantially C-shaped with a first end 112 connected to and integrally formed with the bridge section 106 and a second end 114 defining a curved, flexible arm projecting from the bridge section 106. The C-shaped body of the first connector 102 defines a circular interior cavity 116. An opening 118 to the C-shaped first connector portion 102 is defined at the leading edge 108 of the first connector portion 102 and defines an opening to the cavity 116. The second end 114 of the first connector 102 is configured to flex outward from the first end 112 of the connector 102 to enlarge the opening 118. The second end 114 is resilient and is biased back to its original configuration when any deflecting force is removed.

[0075] The second connector portion 104 is located on the opposite side of the bridge section 106 from the first connector portion 102 and has a mirror image configuration, the same as the first connector portion 102. The second connector portion 104 has a first end 120 connected to and integrally formed with the bridge 106 and a resilient, flexible second end 122. The second connector portion 104 is also C-shaped and has an opening 124 defined between the first end 120 and the second end 122. The opening 124 allows access to an interior cavity 126 defined within the C-shaped second connector portion 104. The first connector portion 102 and the second connector portion 104 are the same dimensions and are each configured to receive a fence post having a circular cross-section.

[0076] The bridge section 106 includes a key slot 168. The key slot is configured to receive a key 186. The key slot 168 is surrounded by a rib structure 169 configured to increase the stiffness of the bridge section 106 and the key slot 168. The rib structure comprises a circular rib and four additional ribs connecting the central circular rib to the connector portions 102, 104. The rib structure 169 is integrally formed with the outer surface of the coupling element 100a. By providing the rib structure 169, the stiffness of the coupling member 100a about its longitudinal axis can be increased. That is, the torsional stress required to achieve a given strain about the longitudinal axis of the coupling member 100a can be increased by introducing the rib structure 169.

[0077] 15, an enlarged underside view of the second connector portion 104 of the coupling member 100a of FIG. 14 is shown. The first connector portion 102 of the coupling member 100a may be a mirror image of the second connector portion 104, such that the coupling member is symmetrical about an axis perpendicular to the longitudinal axis of the coupling member 100a. Accordingly, the features and advantages of the second connector portion 104 described below may also apply to the first connector portion 102 in a mirror image configuration.

[0078] The connector portion 104 includes a curved closure element 142 located at the rear edge of the second connector portion 104 and diametrically opposite the opening 124. The closure element 142 has a total height that is substantially twice the height of the second end 122 of the second connector portion 104. The angular extent of the closure element 142 is equal to the angular extent of the opening 124, and the opening 124 and closure element 142 each have an extent of approximately 90° around the circumference of the second connector portion 104. The closure element 142 is hollow and open at its upper end to reduce weight. The closure element 142 includes a drainage aperture at its base to prevent it from filling with rainwater during use.

[0079] An upstanding positioning tab 149 projects from the upper edge 140 of the second end 122 of the connector portion 104. The positioning tab 149 is centered between the inner wall 134 and the outer wall 136 and is stepped vertically below the level of the closure element 142. A corresponding positioning tab (not shown) is disposed on the second end 114 of the first connector portion 102. A slot 151 is provided on the second end 122 of the second connector portion 104 between the distal end of the second end 122 and the positioning tab 149. The slot is centered between the inner wall 134 and the outer wall 136. A corresponding slot (not shown) is disposed on the second end 114 of the first connector portion 102 between the distal end of the second end 114 and the corresponding positioning tab (not shown).

[0080] The first and second coupling members 100a, 100b are substantially identical, and the locating tabs 149 and slots 151 of the first coupling member 100a are configured to interlock with those of the second coupling member 100b when the fence panel coupler assembly 101 is in a closed position, further securing the first and second coupling members 100a, 100b together. In particular, the interlocking of the locating tabs 149 and slots 151 provides additional torsional stiffness and shear strength. The locating tabs 149 and corresponding locating tabs located on the second and first connector portions 104, 102, respectively, of the first coupling member 100a are configured to cooperate with the slots 151 and corresponding slots located on the second and first connector portions 104, 102, respectively, of the second coupling member 100b. Furthermore, the positioning tabs 149 and corresponding positioning tabs arranged on the second connector portion 104 and the first connector portion 102, respectively, of the second coupling member 100b are configured to cooperate with the slots 151 and corresponding slots arranged on the second connector portion 104 and the first connector portion 102, respectively, of the first coupling member 100a.
