Abstract

Described is an adhesively securable fastener comprising a body having an opening; an adhesive positioned within said body and registering with the opening of the chamber, a plunger means for applying pressure to said adhesive such as against an anvil means thereby adhesively securing the fastener to a substrate. Also described is a method for securing a substrate using the fastener described herein.

Claims

1.

An adhesively securable fastener for securing a first substrate having top and bottom portions to a second substrate having top and bottom portions through aligned apertures therein comprising:

a. an elongated body having an opening and a top portion and further having deflectable tabs opening adjacent to and towards the second substrate at a position juxtaposed to the opening;

the body capable of protruding through the apertures in the substrates with the body top portion capable of contacting the top portion of the first substrate and the deflectable tabs capable of contacting the bottom portion of the second substrate;

b. an adhesive positioned within said body; and

c. registering with the opening of the body a plunger means for applying pressure to said adhesive thereby adhesively securing the fastener to the substrates by movement of at least a portion of the adhesive from the body to the substrate and the deflectable tabs having the ability to lock the bottom portion of the second substrate to it so as to be able to fasten together the body and the substrate.

2. The fastener of claim 1 wherein the plunger means comprises means for rupturing a capsule of adhesive retained therein.

3. The fastener of claim 1 wherein the body is elongated and has a series of holes therein to permit passage of the adhesive therethrough to adhesively secure the body to the substrate.

4. The fastener of claim 1 wherein the adhesive is a quicksetting adhesive.

5. The fastener of claim 1 wherein the adhesive is a micro-encapsulated adhesive.

6. The fastener of claim 1 wherein the adhesive is an anaerobic adhesive.

7. The fastener of claim 6 wherein the adhesive is a micro-encapsulated anaerobic adhesive.

8. A method of securing a fastener to a first substrate having a top and bottom portion through aligned apertures therein comprising the steps:

a. positioning an adhesively securable fastener having an elongated body having an opening, a top portion and deflectable tabs opening adjacent to and towards the second substrate at a position juxtaposed to the body opening such that the top body portion is positioned near the top portion of the first substrate and protrudes through the apertures within the substrates;

said fastener further comprising an adhesive positioned within said body, and registering with the opening of the body, a plunger means for applying pressure to said adhesive;

b. applying pressure to the plunger means;

c. forcing the adhesive from the body;

d. curing the adhesive; and

e. locking the deflective tabs to the bottom portion of the second substrate thereby joining the fastener to the substrates.

9. The method of claim 8 wherein the adhesive is a quicksetting adhesive.

10. The method of claim 9 wherein the quicksetting adhesive is an anaerobic adhesive.

11. The method of claim 8 wherein the adhesive is a micro-encapsulated adhesive.

12. The method of claim 8 wherein the adhesive is a micro-encapsulated anaerobic adhesive.

13. An adhesively securable fastener for securing a first substrate having top and bottom portions to a second substrate having top and bottom portions through aligned apertures therein comprising:

a. an elongated body having an opening and a top portion and further having deflectable tabs at a position juxtaposed to the opening

the body capable of protruding through the apertures in the substrates with the body top portion capable of contacting the top portion of the first substrate and the deflectable tabs capable of contacting the bottom portion of the second substrate;

b. an adhesive positioned within said body; and

c. registering with the opening of the body a plunger means for applying pressure to said adhesive thereby adhesively securing the fastener to the substrates by movement of at least a portion of the adhesive from the body to the substrate and the deflectable tabs having the ability to lock the bottom portion of the second substrate to it so as to be able to fasten together the body and the substrate;

wherein the plunger means contains a plurality of recessed areas for movement of the adhesive therethrough during application of pressure to the adhesive by the plunger.
