The present teachings relate to spades for hardware free mounting to outdoor data distribution terminal pedestals.
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
A primary concern among data communication service providers today is the amount of time and resources required to install and use outside plant data communication equipment such as distribution terminal pedestals. Distribution terminal pedestals are utilized to provide a housed connection point for passive, i.e., non-powered, type connections. For example, distribution terminal pedestals can be utilized to house the connection points of one or more telecommunication central transmission lines to one or more customer service transmission lines. The pedestals generally protect the connection points from various environmental factors, tampering, etc., but can also be opened to allow access by a service person.
At least some known distribution terminal pedestals include a one-piece dome attached to a two-piece base, in which various passive connections can be made. The two-piece base is typically coupled together using hardware, such as nuts and bolts, retaining clips and screws, etc. Additionally, often a spade or stake can be attached to the base to add additional stability to the pedestal when placed in the ground. In such cases, the spade or stake is either integrally formed with one-half of the base or attached to the base using hardware.
Furthermore, initial installation of such pedestals, and subsequent access to the passive connections housed within, typically require the use of tools to fasten and unfasten the hardware coupling the components together. Thus, the requirement of hardware to couple the components together adds considerable parts and labor costs to the installation and servicing of such known pedestals.
According to one aspect of the present disclosure, a spade or stake is configured for hardware free mounting to a telecommunications data distribution terminal pedestal. The spade may include one or more connectors of various types for engaging the pedestal to thereby couple the spade to the pedestal without hardware, and thus without tools. The pedestal may also include one or more connectors for mating with corresponding connectors on the spade.
Further areas of applicability of the present teachings will become apparent from the description provided herein. It should be understood that the description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the present teachings.

The following description is merely exemplary in nature and is in no way intended to limit the present teachings, application, or uses. Throughout this specification, like reference numerals will be used to refer to like elements.
Referring to
As used herein, assembly hardware includes any separate, independent, stand-alone fastening device or mechanism used to couple together two or more components, parts or structures, e.g., components of known data distribution terminal pedestals. Also, as used herein, tools include any hand-held tool used to install such assembly hardware. For example, assembly hardware can include screws, nuts and bolts, rivets, push-in plugs or pins, etc., and the associated tools can include screw drivers, drills, screw guns, rivet guns, wrenches, nut drivers, etc.
In various implementations, the pedestal 10 can be utilized to protect connection points of one or more main, or central, data distribution cables with one or more service lines to customer locations. Typically, such main distribution cables and service lines are run underground to a desired location where they are brought above ground and terminated. The base 14 can be quickly and easily assembled on-site, absent assembly hardware, and partially buried in the ground around the terminal ends of the main cables and service lines. Thus, the terminal ends of the main cables and service lines are enclosed within the interior chamber 26, which can include any interior area of the top cover 18 that may exist above the base 14 when the top cover 18 is coupled to the base 14. Any and all desired connections between the terminal ends of the main cables and service lines can then be made and the top cover 18 installed to enclose the connections. Thus, the connections are disposed within the interior chamber 26 and protected from weather, contaminates, tampering, vandalism, etc.
As illustrated, the first wall structure 30 includes a first longitudinal tongue 46 extending along a first longitudinal edge portion 50 of the base first wall structure 30. The first wall structure 30 additionally includes an opposing second longitudinal tongue 54 extending along an opposing second longitudinal edge portion 58 of the base first wall structure 30. More specifically, the first and second longitudinal tongues 46 and 54 extend from and are coplanar with an interior side of the respective first and second longitudinal edge portions 50 and 58. Accordingly, the first longitudinal tongue 46 forms a first lip 60 with the first longitudinal edge portion 50, and the second longitudinal tongue 54 forms a second lip 64 with the second longitudinal edge portion 58.
Integrally formed with and extending substantially orthogonally from each of the first and second longitudinal tongues 46 and 54 are one or more latching buttons 38. Correspondingly, the second wall structure 34 includes at least one interlocking slot 42 integrally formed within a first longitudinal edge portion 62 and at least one interlocking slot 42 integrally formed within a second longitudinal edge portion 66. The number and location of the interlocking slots 42 are such that for each latching button 38 there is a corresponding interlocking slot 42 within the respective first and second edge portions 62 and 66 of the second wall structure 34. Additionally, although the one or more interlocking slots 42 integrally formed within the second longitudinal edge portion 66 are obscured from view in
Although, as described above, the base first and second wall structures 30 and 34 can respectively include one or more of the latching buttons 38 and corresponding interlocking slots 42,
Each latching button 38 includes a stem 70 integrally formed with and extending substantially orthogonally from the respective longitudinal tongue 46 and 54. Each latching button 38 additionally includes a cap 74 integrally formed at a distal end of the stem 70. The caps 74 are generally flat and extend substantially orthogonally from a longitudinal axis of the stems 70 such that a profile of the latching buttons 38 has substantially a ‘T’ shape. The stem 70 of each latching button 38 is sized to fit within the corresponding interlocking slot 42. Additionally, each latching button 38 is formed such that a longitudinal length of each stem 70 is substantially equal to, or slightly greater than, a thickness of respective first and second edge portions 62 and 66 of the second wall structure 34.
With further reference to
In accordance with various embodiments, the first wall structure 30 includes a pair of latching bosses 78 integrally formed with an interior surface of the first wall structure top portion 22A. Specifically, one latching boss 78 is formed with the top portion 22A interior surface along the first longitudinal edge portion 50, and the second latching boss 78 is formed with the top portion 22A interior surface along the second longitudinal edge portion 58. Although the latching boss 78 integrally formed with the interior surface of the first longitudinal edge portion 50 is obscured from view in
The second wall structure 34 additionally includes a first longitudinal shoulder 82 extending from the top portion 22B along the first longitudinal edge portion 62, and a second longitudinal shoulder 86 extending from the top portion 22B along the second longitudinal edge portion 66. More specifically, the first and second longitudinal shoulders 82 and 86 extend from and are coplanar with an interior side of the top portion 22B. Accordingly, the first longitudinal shoulder 82 forms a first offset 90 with the first longitudinal edge portion 50, and the second longitudinal shoulder 86 forms a second offset 94 with the second longitudinal edge portion 58.
The first and second longitudinal shoulders 78 and 82 each have integrally formed therein a biased latching tab 98. Each latching tab 98 includes a retention aperture 102 and corresponds to a respective one of the latching bosses 78 of first wall structure 30. The retention apertures 102 are sized to receive and engage the respective corresponding latching boss 78 when the first and second wall structures 30 and 34 are coupled together, as described below. As illustrated in
To assemble the base 14, i.e., interlockingly couple the first and second wall structures 30 and 34 together absent assembly hardware, the latching buttons 38 are interlockingly mated with the corresponding interlocking slots 42. More particularly, in various embodiments, the interlocking slots 42 generally have an ‘L’ shape and include a mouth 106 and a locking leg 110. Therefore, the stems 70 of each latching button 38 can be inserted into the mouth 106 of the corresponding ‘L’ shaped interlocking slot 42. The first and second wall structures 30 and 34 can then be moved longitudinally with respect to each other such that the stems 70 are moved into interlocking slot legs 110. Thus, the latching buttons 38 are interlockingly mated with the interlocking slots 42 to interlockingly couple the first and second wall structures 30 and 34 together, forming the base 14 absent assembly hardware.
Additionally, when the latching button stems 70 are fully inserted into interlocking slot mouths 106, leading edges 62A and 66A of the respective second wall structure first and second edge portions 62 and 66 substantially abut the first and second lips 60 and 64 of the first wall structure 30. Similarly, leading edges 50A and 58A of the respective first and second edge portions 50 and 58, at first wall structure top portion 22A, substantially abut the first and second offsets 90 and 94 of the second wall structure top portion 22B. In this position, prior to interlocking the stems 70 within the interlocking slot legs 110, the latching bosses 78 are located below, and aligned with, the biased latching tab apertures 98. Therefore, when one or both of the first and second wall structures 30 and 34 are longitudinally moved with respect to each other to interlocking mate the latching buttons 38 with the interlocking slots 42, the latching bosses are engaged within the respective latching tab apertures 102. Particularly, as the first and second wall structures 30 and 34 are longitudinally moved with respect to each other, the latching tabs 98 are cammed over the latching bosses 78. When the latching button stems 70 approach, or hit, the bottom of the respective interlocking slot legs 110, the latching bosses 78 are generally centered with respective latching tab apertures 110. The biased nature of the latching tabs 98 then forces the latching tabs 98 inward, toward the interior chamber 26, to thereby engage the latching bosses 78 within the respective latching tab apertures 98. Engaging the latching bosses 78 within the respective latching tab apertures 98 substantially retains the interlocked engagement of latching buttons 38 within the latching slot 42.
Furthermore, as the first and second wall structures 30 and 34 are moved together to insert latching button stems 70 into the interlocking slots 42, the first and second longitudinal tongues 46 and 54 slide along the interior surfaces of the second wall structure first and second longitudinal edge portions 62 and 66. Similarly, as the first and second wall structures 30 and 34 are moved together, the first and second longitudinal shoulders 82 and 86 slide along the interior surfaces of the first wall structure first and second longitudinal edge portions 50 and 58, at the top portion 22A. This interlocking alignment of the first and second longitudinal tongue portions and shoulders 46, 54, 82 and 86 with the respective edge portions 62, 66, 50 and 58, aids in aligning the first and second wall structures 30 and 34 during assembly and provides structural stability of the assembled base 14.
In various embodiments, the interlocking slot legs 110 can be formed such that each leg is slightly canted away from the respective leading edges 62A and 66A. Accordingly, as the first and second wall structures 30 and 34 are moved longitudinally with respect to each other and the stems 70 are moved into interlocking slot legs 110, the canting of the legs 110 cause the wall structures 30 and 34 to be pulled toward each other. Therefore, the leading edges 50A, 58A, 62A and 66A, of the respective first and second wall structures 30 and 34, will be pulled into firm abutment with the respective lips 60 and 64 and offsets 90 and 94 of the respective opposing first and second wall structures 30 and 34.
To access the lower portion of interior chamber 26 after the base 14 has been assembled, as described above, the first and second wall structures 30 and 34 can be easily separated by disengaging the latching tabs 98 and lifting up on the first wall structure 30. More specifically, to separate the first and second wall structures 30 and 34, the latching tabs 98 can be pushed outwardly, away from the interior chamber 26 to disengage the latching bosses 78. With the latching tabs 98 disengaged, one or both of the first and second wall structures 30 and 34 can be longitudinally moved with respect to each other such that the latching buttons 38 are moved toward the latching slot mouths 106. The first and second wall structures 30 and 34 can then be separated to provide access to the lower portion of the interior chamber 26.
Referring now to
More particularly, in various embodiments, the second wall structure 34 is structured to include a plurality of biased latching fingers 118. The biased latching fingers 118 are integrally formed with and extend substantially orthogonally from an outer surface of a bottom portion 122 of the second wall structure 34. Additionally, the stability spade 114 includes a plurality of latching windows 126 formed within a proximal end portion 130 of the stability spade 114. Each latching window 126 is sized to receive a corresponding one of the latching fingers 118. To fixedly couple the stability spade 114 to the wall structure 34, absent assembly hardware, the stability spade 114 is pressed against the wall structure bottom portion 130 such that biased latching fingers 118 are engaged within the latching windows 126. The biased latching fingers 118 and corresponding latching windows 126 are structured, or formed, so that latching fingers 118 firmly engage the latching windows 126. Therefore, the stability spade 114 is fixedly mounted to the wall structure 34 and can not be easily removed or dislodged.
As illustrated in
In various embodiments, the second wall structure 34 includes a plurality of raised ribs 134 that include at least one alignment and support slot 138. Additionally, the stability spade 114 includes at least one T-tab 142 structured to mate with a respective one of the alignment and support slots 138 when the stability spade 114 is fixedly connected to the second wall structure 34, as described above. Specifically, a neck 146 of each T-tab 142 is sized to slide into the corresponding alignment and support slot 138 as the stability spade proximal end portion 130 is being pressed against the second wall structure bottom portion 122 to fixedly engage the latching fingers 118 with the latching windows 126. The alignment and support slots 138 and T-tabs 142 aid in aligning the stability spade 114 during assembly and provide structural stability of the stability spade 114 when placed in the ground.
Although
Another embodiment of a stability spade 500 for hardware free mounting to a telecommunications distribution terminal pedestal will now be described with reference to
As best shown in
As illustrated in
As best shown in
The spade 500 may also include aligning elements to engage corresponding features on the base 606 to align and guide the spade 500 relative to the base 606 when the spade 500 is coupled to the base 606 without hardware. These aligning elements include vertical walls 722 and horizontal ribs 724. The vertical walls 722 align with and are received between corresponding walls 826 on the base 606. The horizontal ribs 724 define an opening 730 into which a base rib 828 on the base 606 fits. Thus, when installing the spade 500 on the base 606, these aligning features help guide the spade 500 horizontally and vertically into the correct installed position. After installation of the spade 500, the aligning features further inhibit movement of the spade 500 relative to the base 606.
To couple the spade 500 to the base 606, the spade 500 is moved toward the base 606 with the spade 500 in a position, relative to the base 606, that is somewhat lower than the final installed position. In this lower position, the retaining tab 714 is below the lower edge 816, allowing the spade 500 to be moved into contact with a wall 830 of the base 606. The horizontal ribs 724 and the lead-in portions 710 help align the spade 500 to the correct vertical position relative to the base 606. The vertical walls 722 and the corresponding walls 826 on the base 606 help align the spade 500 to the correct horizontal location on the base 606. As the spade 500 is moved toward the wall 830, the snap connectors 812 engage the lead-in portions 710 and begin to deflect away from the center of the spade 500. Once the snap connectors 812 pass through the snap-catch windows 708, they move, or snap, back toward the center and hold the spade 500 to the base 606. The snap-catch windows 708 are taller than the snap connectors 812, allowing the spade 500 to slide up even while the snap connectors 812 are connecting the spade 500 to the base 606. After snap connectors 812 are so engaged, the user slides the spade 500 upward until a horizontal surface 732 contacts a bottom surface 634, best seen in
As the spade 500 is slid upward, the horizontal ribs 724 are moved into position behind the snap connectors 812. In the final installed position, the horizontal ribs 724 are located behind the snap connectors 812 to prevent the snap connectors 812 from deflecting outwardly and releasing the spade 500 from the base 606. This is aided by upwardly extending foot ribs 736 located on ends the horizontal ribs 724. The foot ribs 736 provide a larger surface for engaging the snap connectors 812 and inhibiting the snap connectors 812 from deflecting outwardly and decoupling from the snap-catch windows 708.
Additionally, sliding the spade 500 upward moves the retaining tab 714 into its final position. As the spade is pushed upward, the retaining tab 714 moves upward and engages the lower edge 816 of the base 606. The retaining tab 714 thus limits separation of the spade 500 away from the lower edge 816 of the base 606 in a horizontal direction.
Finally, the upward sliding of the spade 500 causes the paddle snap 718 to engage the aperture 820. Because the paddle snap 718 includes a protruding button 738, the paddle snap deflects away from the base 606 when the spade is brought toward the base 606 and into contact with the wall 830. When the spade 500 is slid upward to the point where the horizontal surface 732 meets the bottom surface 634 of the base 606, the button 738 aligns with and, due to its resilient nature, snaps into the aperture 820 in the wall 830 of the base 606. Through this engagement with the aperture 820, the paddle snap 718 inhibits sliding movement of the spade 500 relative to the base 606 in a vertical direction.
In the final installed position, the various connectors and aligning elements hold the spade 500 coupled securely to the base 606. The snap connectors 812 and the retaining tab 714 inhibit separation of the spade 500 from the base 606. The horizontal ribs 724, and more particularly the foot ribs 736, prevent deflection of the snap connectors 812, which would permit the spade 500 to separate from the base 606. Finally, the paddle snap 718 prevents the spade 500 from being moved down or up relative to the base 606. This prevents the retaining tab 714 from disengaging from the edge 816 and prevents the foot ribs 736 from being moved away from the position preventing deflection of the snap connectors 812.
The spade 500 may be removed from the base 606 by reversing the installation operations. Specifically, the button 738 on the paddle snap 718 is forced back through the hole 820, thereby deflecting the paddle snap 718 away from the base 606. The spade 500 can then be moved downward, disengaging the retaining tab 714 and moving the foot ribs 736 downwardly and away from the snap connectors 812. The snap connectors 812 are than forced, by the user, to deflect away from each other so that the spade 500 can be removed from the base 606.
The base 14, i.e., the first and second wall structures 30 and 34, the base 606, the spade 114 and the spade 500 can be constructed of any suitable metallic or non-metallic material. Accordingly, they can be formed using any suitable means of fabrication, such as casting or molding. For example, in various embodiments, the base 14 or 606, the spade 500 and/or the spade 114 can be injection molded using any suitable non-metallic plastic or compound, e.g., a glass filled polymer. Additionally, in various embodiments, the spade 114 or the spade 500 can be fabricated as, or fabricated to include, an electrical grounding source to electrically ground the pedestal 10.
