FIGS. 1A-4 illustrate an anchor system 10 for securing elements, such as, for example, shelves, pictures, clocks and other wall hangings, electrical conduit, pipes, wires, and the like to a structure 12. The anchor system 10 can be installed or used with any manmade structure 12, such as, for example, homes, commercial buildings, fences, garages, poles, frames, gutters, railings, and the like. The anchor system 10 can also be installed in caves, mines, trees, and other naturally-occurring structures 12.
The anchor system 10 can include a first anchor member or sleeve 14, an adhesive 16 supported in the sleeve 14, and a second anchor member or pin 18. In the illustrated embodiment of FIGS. 1A-4, the sleeve 14 includes a first end 20, a second end 22, and a length 24 extending between the first and second ends 20, 22. In some embodiments, the sleeve 14 defines an axis 25 extending between the first and second ends 20, 22.
In some embodiments, such as the illustrated embodiment of FIGS. 1A-4, the first end 20 includes an outwardly extending mounting flange 26. In such embodiments, the mounting flange 26 is engageable with a structure 12 to orient the anchor system 10 with respect to the structure 12. More specifically, the mounting flange 26 is engageable with the structure 12 to allow only a desired portion of the anchor system (e.g., the second end 22 of the sleeve 14) to be moved into a bore in the structure 12 and to prevent the entire anchor system 10 from falling into the bore.
The first end 20 can also include an outwardly extending fastener 30 for supporting an element on the structure 12. In the illustrated embodiment of FIGS. 1A-4, the fastener 30 has a generally circular cross-sectional shape and includes a circumferential groove 32 positioned between the mounting flange 26 and a radially outwardly extending lip 36. In this embodiment, elements, such as, for example, wires, string, twine, and the like, can be wound around the fastener 30 to secure additional elements (e.g., pictures and other wall hangings) to the structure 12. In other embodiments, other elements can slidingly and/or lockingly engage the mounting flange 26, the outwardly extending lip 36, and/or the circumferential groove 36.
The sleeve 14 also includes an outer surface 40 extending between the first end 20 and the second end 22. In the illustrated embodiment of FIGS. 1A-4, the sleeve 14 includes radially outwardly extending first and second collars 42, 44 and defines a channel 46 extending circumferentially around the outer surface 40 and extending axially along the outer surface 40 between the first and second collars 44, 46. In some embodiments, such as the illustrated embodiment of FIGS. 1A-4, the channel 46 extends axially along less than the entire length 24 of the outer surface 40 of the sleeve 14. In other embodiments, the channel 46 extends along at least about one-third of the length 24 of the outer surface 40. In still other embodiments, the channel 46 can have other relative lengths and dimensions.
The first collar 42 is engageable with the structure 12 adjacent to a proximal end of the bore in the structure 12. The second collar 44 is engageable with the structure 12 adjacent to a distal end of the bore in the structure 12 to limit movement of the sleeve 14 relative to the structure 12. In some embodiments, such as the illustrated embodiment of FIGS. 1A-4, the first and second collars 42, 44 are sized to frictionally engage an inner surface of the bore. In these embodiments, the first and second collars 42, 44 limit movement of the sleeve 14 axially through the bore and limit rotational motion of the sleeve 14 about a longitudinal axis 48 extending through the bore.
In some embodiments, such as the illustrated embodiment of FIGS. 1-4A, the first and second collars 42, 44 extend circumferentially around the outer surface 40 of the sleeve 14, and, as described in greater detail below, limit the flow of adhesive 16 axially along the outer surface 40 of the sleeve 14. In other embodiments, one or both of the first and second collars 42, 44 extend around less than the entire circumference of the outer surface 40 of the sleeve 14.
As shown in FIGS. 1A-4, in some embodiments, the sleeve 14 can also include protrusions 52 extending outwardly from the outer surface 40 between the first and second collars 42, 44 and extending outwardly into the channel 46. In these embodiments, the protrusions 42, 44 can extend radially outwardly from the outer surface 40 of the sleeve 14 to frictionally engage the inner surface of the bore in the structure 12 to limit rotational movement of the sleeve 14 about the longitudinal axis 48 of the bore and/or to limit axial movement of the sleeve 14 axially through the bore along the longitudinal axis 48.
Alternatively, in some embodiments, the protrusions 52 can extend outwardly from the outer surface 40 a distance less than the radial extent of the first collar 42 and/or the second collar 44. In these embodiments, the protrusions 52 are prevented from engaging the inner surface of the bore in the structure 12 to reduce resistance to movement of the sleeve 14 axially through the bore and/or to reduce resistance to rotational movement of the sleeve 14 in the bore.
In the illustrated embodiment of FIGS. 1A-4, the sleeve 14 also includes an opening 56 extending through the first end 20 and opening into an interior space 58 in the sleeve 14. In these embodiments, the interior space 58 can extend axially through the sleeve 14 between the first and second ends 20, 22 of the sleeve 14. In other embodiments, the interior space 58 can extend substantially less than the entire axial length 24 of the sleeve 14 and can stop short of the second end 22.
As shown in FIGS. 1A-4, apertures 60 can extend radially outwardly through the outer surface 40 of the sleeve 14 between the interior space 58 and the channel 46. In the illustrated embodiment, two apertures 60 extend outwardly through the outer surface 40 of the sleeve 14, are spaced radially around the sleeve 14 at intervals of about 180 degrees, and are positioned adjacent to the second end of the sleeve 14. In other embodiments, one, three, or more apertures 60 can extend outwardly through the outer surface 40 of the sleeve 14 and these apertures 60 can be spaced at regular or irregular intervals radially around the sleeve 14. Alternatively or in addition, the apertures 60 can be spaced adjacent to the first end 20 of the sleeve 14 or at any other position along the length 24 of the sleeve 14 to communicate with the channel 46.
The adhesive 16 can be supported in the interior 58 of the sleeve 14 adjacent to the second 22 of the sleeve 14. In some embodiments, such as the illustrated embodiment of FIGS. 1A-4, the adhesive 16 can be housed or at least partially housed in a pouch, a bag, or other storage capsule 64. In these embodiments, the sleeve 14 can include a bur or protrusion 66 extending into the interior space 58 and operable to puncture the capsule 64.
In some embodiments, the adhesive 16 can be an epoxy. In other embodiments, other adhesives, such as, for example, epoxy hybrids, resorcinol formaldehyde, phenol resorcinol formaldehyde, melamine formaldehyde, urea formaldehyde, phenolics, modified phenolics, polyaromatic high-temperature resins, polyesters, vinyl esters, polyurethanes, cyanoacrylates, modified acrylics, moisture-cure isocyantes, UV-cure cyanoacrylates, silicones, UV-cure silicones, acrylics, UV-acrylics, solvent-based thermoplastic cements, and combinations of such elements can also or alternately be used. In still other embodiments, other adhesive materials can also or alternately be used. As used herein and in the appended claims, the term “adhesive” includes cohesive and other bonding elements, and mixtures of bonding elements and cohesives.
The pin 18 includes a first end 68 and a second end 70. In the illustrated embodiment, the pin 18 has a substantially circular cross-sectional shape extending between the first and second ends 68, 70. In other embodiments, the pin 18 can have any other cross-sectional shape desired, such as, for example, square, triangular, rectangular, trapezoidal, or any other polygonal shape, oval, irregular, and the like.
In the illustrated embodiment of FIGS. 1A-4, the second end 70 of the pin 18 has a substantially smooth outer surface 72, is movable axially through the interior space 58, and is rotatable about the longitudinal axis 48 relative to the sleeve 14. As shown in FIGS. 1A-4, the first end 68 of the pin 18 can include radially outwardly extending protrusions 78 spaced along at least a portion of the first end 68 and extending radially outwardly for frictionally engaging the sleeve 14. In other embodiments, the protrusions 78 can be spaced along the entire length or substantially the entire length of the pin 18. In still other embodiments, the pin 18 can have a substantially smooth outer surface 72 extending between the first and second ends 68, 70. In these and other embodiments, the pin 18 can have a tapered and radially inwardly extending cross-sectional shape so that the first end 68 has a first cross-sectional area and the second end 70 has a second, smaller cross-sectional area.
In embodiments such as the illustrated embodiment of FIGS. 1A-4 having a pin 18 with outwardly extending protrusions 78, the pin 18 can be supported in the sleeve 14 in a first position (shown in FIGS. 1A and 1B), in which the outwardly extending protrusions 78 engage the sleeve 14 and limit axial movement of the pin 18 and rotational movement of the pin 18 relative to the sleeve 14. To simplify instillation, the pin 18 can be maintained in the first position until an operator positions the anchor system 10 in a structure 12 in a desired orientation. The operator can then force the pin 18 inwardly into the interior 58 of the sleeve 14 and toward a second position (shown in FIGS. 2A and 2B), in which the pin 18 moves toward the second end 22 of the sleeve 14 forcing the adhesive 16 rearwardly toward the second end 22 of the sleeve 14 and radially outwardly through the apertures 60 into the channel 46. The operator can then continue to move the pin 18 rearwardly toward a third position (shown in FIGS. 3A and 3B), in which the first end 68 of the pin 18 is substantially inline or flush with the first end 20 of the sleeve 14, causing the adhesive 16 to substantially fill the channel 46.
In operation, an operator forms a bore in a structure 12 and inserts the sleeve 14 into the bore so that the collars 42, 44 and/or the protrusions 52 frictionally engage the structure 12, preventing the sleeve 14 from rotating about the longitudinal axis 48 relative to the structure 12 and preventing the sleeve 14 from moving axially through the bore. In embodiments having a mounting flange 26, the operator forces the sleeve 14 into the bore until the mounting flange 26 engages an outer surface of the structure 12.
The operator then inserts the pin 18 and the adhesive 16 into the interior space 58 of the sleeve 14 and forces the pin 18 rearwardly toward the second end 22 of the sleeve 14. Alternatively, in embodiments in which the pin 18 is supported in the sleeve 14 in the first position, the adhesive 16 can be pre-positioned in the interior space 58.
In the illustrated embodiment of FIGS. 1A-4, the pin 18 is driven into the sleeve 14 with a hammer. In other embodiments, other tools, including drills, screwdrivers, and the like can also or alternately be used to move the pin 18 from the first position toward the third position. In still other embodiments, an operator can move the pin 18 into the sleeve 14 without the assistance of tools.
In embodiments, such as the illustrated embodiment of FIGS. 1A-4 having an adhesive capsule 64, the pin 18 forces the adhesive capsule 64 rearwardly into engagement with the protrusion 66, which punctures the adhesive capsule 64.
As shown in FIGS. 2A and 2B, continued rearward movement of the pin 18 toward the second position, forces the adhesive 16 radially outwardly through the apertures 60 and into the channel 46. As the pin 18 is moved toward the third position (shown in FIGS. 3A and 3B), the adhesive 16 flows around the protrusions 52 located along the outer surface 40 of the sleeve 14 and substantially fills the channel 46. The adhesive 16 then bonds the sleeve 14 to the structure 12. In some embodiments, at least some of the adhesive 16 remains in the interior space 58 and bonds the pin 18 to the sleeve 14.
In addition to acting as a plunger and forcing the adhesive 16 rearwardly, in some embodiments, the pin 18 forces the sleeve 14 radially outwardly. In some such embodiments, the protrusions 78 on the outer surface 72 of the pin 18, or alternately, the tapered shape of the pin 18, cause the first end 20 and/or the second end 22 of the sleeve 14 to radially expand and to more firmly engage the inner surface of the bore in the structure 12. In these embodiments, the radial expansion of the sleeve 14 can also form a seal between the first collar 42 and the structure 12 and/or between the second collar 44 and the structure 12 to limit movement of the adhesive 16 and to prevent movement of the adhesive 16 out of the channel 46.

As shown in FIG. 39, the anchor system 810 includes a first collar 842 positioned adjacent to a first end 820 of the sleeve 814 and a second collar 844 positioned adjacent to a second end 822 of the sleeve 814. In some embodiments, such as the illustrated embodiment of FIG. 39, the first and second collars 842, 844 are deformable to at least partially engage the structure 812 and to prevent movement of adhesive axially beyond the first and second ends 820, 822 of the sleeve 814.
As shown in FIG. 39, the first and second collars 842, 844 can also include outwardly extending protrusions 888, which are deformable to at least partially engage the structure and to prevent movement of adhesive axially beyond the first and second ends 820, 822 of the sleeve 814. In the illustrated embodiment of FIG. 39, a pair of protrusions 888 extends circumferentially around each of the first and second collars 842, 844 to form a labyrinth seal 890 adjacent to the first and second ends 820, 824 of the sleeve 814.
In some embodiments, such as the illustrated embodiment of FIG. 39, the channel 846, or portions of the channel 846, extends helically around the outer surface of the sleeve 814. In these embodiments, the channel 846 can extend across or around outwardly extending protrusions 852 positioned along the outer surface of the sleeve 814.
The embodiments described above and illustrated in the figures are presented by way of example only and are not intended as a limitation upon the concepts and principles of the present invention. As such, it will be appreciated by one having ordinary skill in the art that various changes are possible. For example, various aspects of the present invention are described above as having a circular cross-sectional shape or as having elements positioned radially outwardly. It should be noted that such constructions are only presented by way of example, and are not intended to be limiting regarding cross-sectional shape of the sleeve 14, the pin 18, the adhesive 16, or the other elements of the anchor system 10.
