The present disclosure relates generally to connection systems, and more particularly relates to anchoring devices for use with a connection system.
A number of cable connecting devices are available for securing a free end of a cable to a support structure such as a wall, post, rail, or the like. In one example, a connecting device is formed as a lag screw and is configured to be threaded into the support structure and act as an anchor for attachment of the cable to the support structure. In another example, the connecting device wraps around the support structure (e.g., post or rail) to provide connection of the cable to the support structure. In a further example, the connecting device extends completely through the support structure and is anchored on an opposite or back side of the support structure.
These known solutions for securing a cable to a support structure have disadvantages depending on, for example, the shape, size and materials of the support structure and the load requirements for the cable. Some support structure are so large in size that it is impractical to wrap a connecting device or cable around the support structure. Other support structures have a thickness or material composition that does not permit boring completely through the support structure or extending the connecting device through the support structure.
Opportunities exist for improvements in connecting devices used to secure a cable to a support structure.
One aspect of the present disclosure relates to an anchor assembly that includes an anchor member and a base plate. The anchor member is configured to releasably connect to a cable connector. The base plate includes inner and outer primary surfaces, an aperture, and an anchor seat. The inner primary surface is configured to contact a surface of a support structure. The aperture extends through the base plate and is configured to receive a shank of the connector. The anchor seat is positioned on the inner primary surface and is configured to support the anchor member.
The anchor member may include a polymeric material. The anchor member may have a bore that receives a portion of the shank. The anchor member may be pivotally mounted to the anchor seat. The anchor member may be mounted to the anchor seat with an interference fit connection. The base plate may include a boss extending from the inner primary surface and configured to extend into a boss recess formed in an adjacent positioned anchor assembly or in a boss aperture of the support structure. The aperture may have a length and a width, wherein the length is greater than the width to permit pivotal movement of the connector relative to the base plate.
Another aspect of the present disclosure relates to an anchor assembly that includes a base plate, a connector, and an anchor. The base plate has a connector aperture. The connector includes a shank that is configured to extend through the connector aperture. The anchor has a bore that is configured to receive the shank of the connector. A position of the connector is adjustable relative to the anchor and base plate
The base plate may include at least one boss aperture configured to receive at least one boss of an adjacent positioned anchor assembly to connect the base plate to the adjacent positioned anchor assembly. The anchor may be pivotally mounted to the base plate. The anchor may be configured to permit pivotal movement of the connector relative to the base plate. The anchor may be integrally formed as a single piece with the base plate. The anchor may hold the connector in a fixed orientation relative to the base plate. The connector aperture may have an elongate shape. The base plate may include a boss configured to extend into a boss recess formed in an adjacent positioned anchor assembly. The boss may provide a snap-fit connection between the base plate and the adjacent positioned anchor assembly.
A further aspect of the present disclosure relates to a method of connecting to a support structure. The method includes providing an anchor assembly comprising a base plate, a connector, and an anchor member, wherein the base plate has a connector aperture and an anchor seat. The method also includes extending a shank of the connector through the connector aperture and into engagement with the anchor member, positioning the anchor member in the anchor seat, and mounting the base plate to a surface of the support structure with the anchor member, anchor seat, and at least a portion of the shank positioned in a recess formed in the support structure.
The base plate may include a boss configured to extend into a boss recess formed in an adjacent positioned anchor assembly. The boss and the anchor seat may extend from a common surface of the base plate. The anchor member may be pivotally mounted to the anchor seat to permit pivotal movement of the connector relative to the base plate. Mounting the base plate may include securing the base plate to a surface of the support structure. The anchor assembly may further include at least one spring biasing member configured to bias the base plate into contact with the surface of the support structure.
The foregoing has outlined rather broadly the features and technical advantages of examples according to the disclosure in order that the detailed description that follows may be better understood. Additional features and advantages will be described hereinafter. The conception and specific examples disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present disclosure. Such equivalent constructions do not depart from the spirit and scope of the appended claims. Features which are believed to be characteristic of the concepts disclosed herein, both as to their organization and method of operation, together with associated advantages will be better understood from the following description when considered in connection with the accompanying figures. Each of the figures is provided for the purpose of illustration and description only, and not as a definition of the limits of the claims.
A further understanding of the nature and advantages of the embodiments may be realized by reference to the following drawings. In the appended figures, similar components or features may have the same reference label.
While the embodiments described herein are susceptible to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and will be described in detail herein. However, the exemplary embodiments described herein are not intended to be limited to the particular forms disclosed. Rather, the instant disclosure covers all modifications, equivalents, and alternatives falling within the scope of the appended claims.
The present disclosure is generally directed to cable connection systems, devices, and methods. More particularly, the present disclosure is directed to systems, devices, and methods used to secure a cable to a support structure such as a post, wall, rail, or the like. One aspect of the present disclosure relates to an internal post insert or mounting structure used to anchor the cable connection system to a support structure. Aspects of the present disclosure may be used in other applications besides an internally positioned insert that is located within a support structure such as a post. For example, the internal post inserts disclosed herein may be positioned at other locations such as, for example, on a back side of a post, wall, or other support structure relative to the direction of travel of the cable away from the post.
Generally, the cable connection systems and devices described herein may be referred to as internal post inserts, internal inserts, post inserts, anchor inserts, or any of a variety of other names. In one example, a cable anchor assembly may provide a device that allows for a fixed or articulating anchoring point within a void in a structural element (e.g., post or rail) that is accessible from, for example, a hole formed in a wall of the structural element or an open end of the structural element. In addition to providing an anchor point for attachment of hardware to the structural element, the devices and methods disclosed herein may also provide additional support to the wall of the structural element as additional loads are introduced into the anchoring point. The devices and methods disclosed herein may also provide for a boss formed into a surface of the cable anchor assembly that is used to locate into a hole formed in the wall of the structural element that will limit movement of the device relative to the structural element. The devices and methods described herein may be designed to be used with cable connectors as an interface with the cables. The devices and methods described herein may use an anchor feature such as a shouldering pin that facilitates attachment of a cable connector. Other embodiments may implement a sphere with a socket as opposed to a cylindrical structure to facilitate a similar pivoting motion. A ball and socket design may permit rotation about additional axes rather than a single axis pivot motion provided by a cylindrical-shaped pin.
Another aspect of the present disclosure relates to a pivotal connection of a cable and its associated cable connector relative to the support structure. In one example, a cable anchor assembly includes a base plate that is fixed to a surface of the support structure, and an anchor to which the cable connector is adjustably secured. The anchor pivots relative to the base plate to provide a pivotal connection of the cable connector (and associated cable) relative to the base plate and support structure. In other embodiments, the cable connector is mounted to the base plate in a fixed angle orientation. The angled orientation may be perpendicular, parallel, or any angle there between.
The cable connector may be a swivel cable connector. The cable connector may include a threaded shank or post portion that is secured to the base plate via an anchor feature. The cable connector may also include a lock body and associated cable lock assembly that is connected to a free end of the cable. The lock body is able to rotate or swivel relative to the shank portion of the cable connector. This design provides for independent rotation of the shank portion relative to the base plate (e.g., via the anchor feature) for purposes of connecting the cable connector to the base plate and adjusting an axial position of the cable connector to the base plate to alter tension in the cable. The cable connector may include a swageless feature as part of the cable lock assembly. The swagelessfeature may operate to connect the cable connector to a free end of the cable.

Base plate 12 is shown having a generally rectangular shape. Other shapes are possible including, for example, an oval or oblong shape, a square shape, a circular shape, or the like. The position of first and second step features 32, 34 and shape and size of first and second end portions 37, 38 may permit stacking or overlapping of portions of base plate 12 with adjacent positioned base plates.
Connector aperture 24 may have a greater length L than width W. The increased length L may permit pivotal movement of cable connector 14 relative to base plate 12. The greater the length L, the greater the range of pivotal movement possible for cable connector 14 relative to base plate 3.
In other embodiments, connector aperture 24 may have other shapes such as a circular shape. A circular shaped connector aperture 24 may provide an aperture that accommodates and/or interface with a sphere shaped anchor 16 that provides 360° rotation relative to base plate 12.
Base plate 12 may be oriented in a position shown in
The anchor seat 26 may be sized to receive the anchor member 16. In one example, anchor seat 26 holds the anchor member 16 in a mounted position to base plate 12 with a snap-fit or interference-fit connection. The anchor seat 26 may include a plurality of contoured surfaces that interface with or mate with contoured outer surfaces of anchor member 16. Anchor seat 26 may include seat portions positioned on opposing sides of connector aperture 24 as shown in at least
Boss aperture 28 is sized to receive a boss 30 of an adjacent positioned base plate 12. Boss aperture 28 and first step feature 32 together may help align base plate 12 with an adjacent positioned base plate and provide a releasable connection there between. Boss aperture 28 may have a circular shape or any shape that matches the shape of boss 30 received therein. Boss 30 is shown having a cylindrical shape with a circular cross-section.
Boss 30 is shown extending from outer primary surface 22 in the same direction as anchor seat 26. In other embodiments, the positions of boss aperture 28 and boss 30 may be switched so that boss aperture 28 is formed in first end portion 37 and boss 30 extends from inner primary surface 20 at second end portion 38. In other embodiments, a plurality of boss apertures 28 and bosses 30 may be positioned on a single base plate 12. Boss 30 may extend into a boss aperture formed in the support structure to assist in orienting base plate 12 relative to the support structure.
In at least some examples, boss aperture 28 may be used for other purposes besides receiving a boss 30. For example, boss aperture 28 may be receptive of a fastener such as a screw or bolt that is used to secure base plate 12 to a support structure. Many different types of fasteners or other connecting features may be used to secure base plate 12 to a support structure. For example, a fastener in combination with a bonding agent (e.g., an adhesive) may be used, or a barb may be used alone or in combination with a weld.
Lip 36 may extend from inner primary surface 20 around a periphery of connector aperture 24. Lip 36 may be inserted into a recess or aperture formed in a surface of the support structure to which base plate 12 is mounted. Lip 36 may assist in connecting base plate 12 to the support surface. Lip 36 may limit rotational movement of base plate 12 relative to the support structure. Lip 36 may provide an aligning function to help orient base plate 12 in a certain orientation relative to the support structure. Lip 36 may provide, at least in part, a stop surface that is contacted by cable connector 14 to limit pivotal movement of cable connector 14 relative to base plate 12 (see
The thicknesses T1, T2, T3 are typically each in the range of about 0.5 millimeters to about 5 millimeters, and more particularly about 1 millimeter to about 3 millimeters. The thicknesses T1, T2 are typically about 25% to about 90% of T3 and more particularly about 30% to about 50% of T3. The thicknesses T1, T2, T3 may be optimized to provide overlapping and mating interfaces between base plate 12 and adjacent positioned base plates. A series of base plates 12 may be arranged in line with each other with the first and second end portions 37, 38 overlapping each other and bosses 30 positioned within boss apertures 28 (see
Cable connector 14 includes a stud or shank 40 that includes exterior thread 42 at one end thereof The thread 42 may threadably engage a threaded bore of anchor 16. In other embodiments, shank 40 may connect to anchor 16 with other connection features, such as permanent connection features rather than the adjustable connection provided by threads 42.
A free end of a cable (e.g., cable 80 shown in
Anchor member 16 includes an anchor aperture 70, a plurality of contoured surfaces 72, and a raised portion 74 (see
Anchor member 16 may be secured to base plate 12 in any number of ways including, for example, being pivotally attached to anchor seat 26 using a snap-fit connection, interference-fit connection, fastener, or the like. In at least some examples, anchor member 16, when connected to base plate 12, maintains a fixed position in all directions of motion (e.g., rotational, translational, axial, etc.). An example of an anchor member 16 that is fixed relative to base plate 12 is shown and described below with reference to
Referring now to
Base plate 112 includes inner and outer primary surfaces 120, 122, a connector aperture 124, a boss aperture 128, a boss 130, first and second step features 132, 134, a lip 136, end portions 137, 138, and a center portion 139. Connector aperture 124 has a generally circular shape with a constant width W. Boss aperture 128 is receptive of a boss 130 of an adjacent positioned base plate 112. Boss aperture 128 may have substantially the same shape and size as boss 130. Boss 130 is shown having a cylindrical shape with a circular cross-section. Boss 130 extends from outer primary surface 122 in the same direction in which anchor member 116 extends from base plate 112.
Lip 136 extends around a periphery of connector aperture 124. Lip 136 may be used to orient and help maintain an orientation of base plate 112 relative to a support surface to which cable anchor assembly 100 is connected, as shown in at least
Anchor member 116 may include an anchor aperture 170. Anchor aperture 170 may be threaded and sized to receive threaded shank 40 of cable connector 14. When assembled, shank 40 extends through connector aperture 124 and into threaded engagement with anchor aperture 170. When cable connector 14 is connected to a cable or other structure (e.g., cable 80), rotating shank 40 relative to base plate 12 advances or retracts cable connector 14 relative to anchor member 16.
Base plate 212 includes inner and outer primary surfaces 220, 222, a connector aperture 224, first and second spring biasing arms 225A, 225B, an anchor seat 226, a boss aperture 228, and a boss 230 having first and second connecting arms 231A, 231B. Base plate 212 may also include first and second step features 232, 234, a lip 236, first and second end portions 237, 238, and a center portion 239. The connect aperture 224 may be receptive of a connecting member such as cable connector 14, which extends through connector aperture 224 and into engagement with an anchor (e.g., anchor member 16) that is secured to base plate 212 at anchor seat 226.
Boss aperture 228 may be shaped and sized to receive boss 230 of an adjacent positioned anchor assembly. Boss aperture 228 is shown in
Many other designs are possible for providing a releasable connection between adjacent positioned base plates 212. In other arrangements, multiple boss members that are positioned spaced apart from each other along one of the inner or outer primary surfaces 220, 222 and may be inserted into a plurality of boss apertures 228 formed in the base plate of an adjacent anchor assembly. In at least some arrangements, the connection between the boss 230 and boss aperture 228 may provide a permanent connection in which no disconnection is possible without damaging features of the base plate (e.g., a destructive disconnection).
The first and second step features 232, 234 may provide abutment surfaces against which the first and second end portions 237, 238 of adjacent position base plates may connect to limit relative rotational movement between adjacent position base plates 212. The combination of a connection between boss aperture 228 and boss 230 along with contact between the first and/or second step features 232, 234 and one of the end portions 237, 238 may limit relative movement between adjacent connected base plates 212 in a plurality of translational and rotational directions. In at least some arrangements, one objective is to provide an assembly of interconnected base plates (and associated anchor assembly features) that remains connected prior to, during and after insertion into a receiving recess of a support structure (e.g., recess 84 of support structure 82 shown in
Lip 236 may have a shape and size that assists in aligning the base plate 212 relative to an aperture 86 of support structure 82 (see
Base plate 212 may include one or more spring biasing arms 225A, 225B that assists in biasing plate 212 into contact with specific surfaces of the support structure 82. For example, spring biasing arms 225A, 225B may bias base plate 212 toward aperture 84 so that lip 236 extends into aperture 84. The biasing force supplied by spring biasing arms 225A, 225B may help hold the base plate 212 in a particular orientation relative to one or more of the apertures 86 of support structure 82 (e.g., during shipping and installation).
Each base plate 212 may include a pair of spring biasing arms 225A, 225B that are positioned in a way that provide balanced application of biasing force to base plates 212. In some arrangements, the spring biasing arms 225A, 225B are positioned on opposite sides of anchor seat 226 along the center portion 239. The spring biasing arms 225A, 225B may have an elongate structure that is oriented in parallel with a length dimension of base plate 212. Other embodiments are possible in which the spring biasing arms are arranged at other orientations and positions relative to the anchor seat 226 or other features of the base plate 212.
The spring biasing arms 225A, 225B may have a free or detached end and a secure or anchor end. The free end may move toward and away from surfaces of the support structure when inserting base plate 212 into recess 84 of support structure 82. Varying the dimensions of the spring biasing arms 225A, 225B may result in adjustment of the biasing force applied. Dimensions include, for example, a length, width, thickness, angle of extension from center portion 239, a bend angle of the free distal end portion relative to the attached anchor end portion, and the like. Some arrangements include only a single spring biasing arm 225, while other embodiments may include three or more spring biasing arms for each base plate 212. In at least some examples, the spring biasing arms 225A, 225B are co-molded with remaining portions of the base plate 212. Alternatively, the spring biasing arms 225A, 225B may be molded integrally as a single piece with remaining portions of base plate 212. In further embodiments, spring biasing arms 225A, 225B may be formed separately from remaining portion of the base plates 212, and attached in a separate connecting step and/or assembly step using, for example, a fastener, bonding agent, or the like.
The base plates 312 may be connected to an adjacent base plate via a connection between boss aperture 328 and a boss 330 of the adjacent base plate (or vice versa) to provide a string of interconnected base plates 312. Inter-connected base plates 312 may be disconnected from each other when a predetermined force is applied in an opposite direction to a direction of insertion of boss 330 into boss aperture 328 to disconnect and remove boss 330 from boss aperture 328. In typical use, such as when assembling together a plurality of base plates 312, inserting the inter-connected base plates into recess 84 of support structure 82, shipping and/or installing support structures 82 that include interconnected base plates 312, and other activities, the base plates 312 remain interconnected at all times.
In at least some embodiments, a relatively long string of individual base plates 412A-C may be connected to each other to provide ease of inserting the same into recess 84 of support structure 82. For example, a string of 5 to 10 individual anchor members 412A-C may be connected to each, and may be disconnected or severed in any combination such as groups of two, three or ten. In some embodiments, the string of one or more individual base plates 412A-C may be molded as one single piece.
The base plate assembly 512 may be formed as a single piece. One or more of the individual base plates 512A-C may be separable from the others along one of the break lines 527. Individual base plates members 512A-C may be formed, disconnected from each other, or provided in any combination of numbers of base plates according to the same or similar examples described with reference base plate assembly 412 described with reference to
A spacer member may be used when inserting any one of the base plates 212, 312, 412, 512 into a support structure, such as into the recess 84 of support structure 82. The spacer may be positioned between the inner primary surface of the base plate and a surface within recess 84 in which the connector apertures 86 are formed. The spacer facilitates the base plate to move axially within the recess 84 without the lip feature 36 moving into the connector aperture 86. The spacer may be removed once the lip 36 of any given base plate is aligned with an intended connector aperture 86 into which the lip 36 is to be inserted. The base plate may include a groove or recess feature formed on the inner primary surface 20 to provide additional space for the spacer to fit between the base plate and the respective surface within recess 84 of support structure 82.
