Abstract

A method, process and machine to anchor objects to a surface using an encapsulated compound such as adhesive, expanding glue, hardening agent or other reactive and/or bonding substance intended for single use in a single anchor installation.

Claims

1. An anchor system comprising:

a fastener rod defining a rod axis;

an anchor comprising a plurality of prongs configured to radially expand with respect to the rod axis as the fastener rod is inserted into the anchor;

an encapsulated substance;

wherein the encapsulated substance is held within one or more of the following;

a sealed chamber of the anchor; and

a capsule configured to insert into the anchor;

and wherein the encapsulated substance is released during insertion of the fastener rod into the anchor.

2. The anchor system of claim 1 wherein the encapsulated substance is an adhesive.

3. The anchor system of claim 1 wherein the encapsulated substance is expanding.

4. The anchor system of claim 1 wherein the encapsulated substance is an expanding adhesive.

5. The anchor system of claim 4 wherein the fastener rod is a screw and the encapsulated substance is held within the capsule.

6. The anchor system of claim 5 wherein the anchor is a sleeve anchor.

7. The anchor system of claim 6 wherein the encapsulated substance further comprises polyurethane.

8. The anchor system of claim 7 wherein the encapsulated substance hardens after exposure to air.

9. The anchor system of claim 1 wherein the fastener rod is a screw.

10. The anchor system of claim 1, wherein the encapsulated substance is held within the capsule, and wherein the capsule is configured to removably insert into the anchor.

11. The anchor system of claim 1, wherein:

the encapsulated substance is held within the capsule;

the fastener rod comprises a point, the point configured to puncture the capsule as the point enters the capsule and to puncture the capsule again as the point exits the capsule.

12. The anchor system of claim 1, wherein:

the anchor is configured to be inserted through a front side of a surface and to extend out a back side of the surface; and

the encapsulated substance is configured to be released to the back side of the surface.

13. The anchor system of claim 12, wherein:

the encapsulated substance is an expanding adhesive; and

the adhesive is configured to expand to adhere the anchor to the front side of the surface, to adhere the anchor to the back side of the surface, and to adhere the fastener rod to the anchor.

14. The anchor system of claim 1, wherein:

the encapsulated substance comprises two components, the substance configured to harden when the two components mix; and

the chamber or capsule defines at least two compartments, each compartment holding a respective one of the two components.

15. The anchor system of claim 1, wherein:

the plurality of prongs define at least one gap therebetween; and

the encapsulated substance is configured to be released within the gap.

16. The anchor system of claim 15, wherein:

the anchor further comprises an insertion end configured to receive the fastener rod, and a prong end opposite the insertion end;

the anchor defines a chamber, the chamber being the sealed chamber or an unsealed chamber; and

the gap extends from the chamber to the prong end.

17. The anchor system of claim 1, wherein:

the encapsulated substance is held within the capsule;

the anchor defines an unsealed chamber; and

the capsule is positioned within the chamber.

18. The anchor system of claim 17, wherein:

the capsule comprises a covering portion and a covered portion; and

the covered portion is inserted into the chamber first.

19. The anchor system of claim 17, wherein a shell of the capsule is a hardened form of the encapsulated substance.

20. The anchor system of claim 17, wherein:

an exterior of the capsule substantially conforms to an interior of the chamber.
