Abstract

In various embodiments, a hot melt device comprising a heating device that is automatically or manually triggered is configured so as to have its melt surface applied bringing a thermoplastic material in its solid form into contact with a surface via mechanical extrusion; using a heater to heat the thermoplastic material to a temperature above a melting temperature of the thermoplastic material while maintaining the contact of the thermoplastic material with the surface; allowing the heated thermoplastic material to cool to a temperature that is below the thermoplastic material's melting temperature; and allowing the heated thermoplastic material to bond the hot melt apparatus to the contacted surface without a solvent or use of a curing chemical reaction when the heated thermoplastic material is cooled to below the thermoplastic material's melting temperature while remaining connected to the structural body.

First claim

What is claimed is:

1. A hot melt apparatus, comprising:
a. a structural body;
b. an extrudable solid form thermoplastic material connected to the structural body, the extrudable solid form thermoplastic material comprising a mechanically extrudable solid form thermoplastic material which is extrudable onto a surface to be joined when the extrudable solid form thermoplastic material is heated and which solidifies while remaining connected to the structural body as the heated solid form thermoplastic material cools;
c. a controllable heater connected to the structural body and to the solid form thermoplastic material, the controllable heater comprising a heat generator adapted to actively heat the solid form thermoplastic material to a temperature above its melting temperature and to actively cool to a temperature which allows the heated solid form thermoplastic material to cool and solidify without the use of a solvent; and
d. a material manager operatively connected to the hot melt apparatus, the material manager comprising a plow shape configured to aid in providing for movement, lifting, and retention of moveable surface materials of the object.

2. The hot melt apparatus of claim 1 , wherein the solid form thermoplastic material further comprises a shape adapted to improve a bond of the thermoplastic material joined with the surface.

3. The hot melt apparatus of claim 2 , wherein the shape comprises a geometric profile comprising a varying thickness of melted thermoplastic material.

4. The apparatus of claim 2 wherein the thermoplastic material comprises an electrically conductive material able to provide a grounding path through the thermoplastic material.

5. The hot melt apparatus of claim 1 , further comprising an interchangeable interface disposed intermediate the structural body and the controllable heater.

6. The hot melt apparatus of claim 5 , wherein:
a. the interchangeable interface comprises an upper portion connected to the structural body and a lower portion connected to the controllable heater and to the upper portion, the upper portion and the lower portion being selectively disconnectable from each other; and
b. the heater and the thermoplastic material are integral and are selectively disconnectable to the structural body.

7. The apparatus of claim 1 , further comprising a separable interface disposed intermediate the heater and the thermoplastic material, the separable interface comprising an upper portion connected to the heating mechanism and a lower portion selectively attachable from the upper portion, the lower portion permanently attached to the thermoplastic material.

8. The apparatus of claim 7 , wherein the separable interface is adapted to create an evenly distributed thermal transfer of heat into the thermoplastic material.

9. The apparatus of claim 7 , wherein the separable interface comprises a thermally conductive material, a thermally non-conductive material, an electrically conductive material, or an electrically non-conductive material.

10. The apparatus of claim 7 , wherein the separable interface comprises a metal, a plastic, or a ceramic.

11. The apparatus of claim 1 , further comprising a mechanical integrator, configured to allow the hot melt apparatus to be mechanically integrated to an object to become a tool or structural extension of the object.

12. The apparatus of claim 1 , further comprising an electrical integrator configured to allow the hot melt apparatus to be electrically integrated to an object and provide an electrical pathway to be established with the object to support the operation of the hot melt apparatus.

13. The apparatus of claim 12 , further comprising an electrically conductive cable operatively in communication with the electrical integrator of the hot melt apparatus at a first end and with the object at a second other end, the electrically conductive cable operative to create an electrical ground path between the object and a secondary object.

14. The apparatus of claim 13 further comprising a pair of the hot melt apparatuses whose electrical integrators are operatively interconnected by an electrically conductive cable, the electrically conductive cable operative to create an electrical ground path when the pair of hot melt apparatuses are bonded separately to the object and the secondary object.

15. The hot melt apparatus of claim 1 , further comprising a cable manager operatively connected to the hot melt apparatus, the cable manager configured to provide positioning, placement and retention of cables, ropes, or tethers.

16. The hot melt apparatus of claim 15 , wherein the cable manager comprises a hook shape.

17. The apparatus of claim 1 wherein the controllable heater comprises an electro-chemical heater activated using a low power electrical signal.

18. The apparatus of claim 1 wherein the controllable heater comprising a chemical-based heater activated through mixing of chemicals.

19. A double-sided hot melt apparatus, comprising:
a. a shared structural body comprising a first end and second end; and
b. a pair of hot melt apparatuses, each hot melt apparatus comprising:
i. a solid form thermoplastic material connected to and disposed at the first end and the second end of the shared structural body, the solid form thermoplastic material mechanically extrudable onto a surface of an object to be joined when the solid form thermoplastic material is heated, the solid form thermoplastic material solidifying while remaining connected to the structural body as the heated solid form thermoplastic material cools;
