Abstract

A flask stand is configured to support a flask and includes a base ring and a plurality of legs. The base ring is configured to support a lower portion of the flask. Each leg is secured to the base ring and extends outward from the base ring. Each leg includes a body, a lattice, and an elastomeric foot. The body includes a first end portion that is secured to the base ring with the foot portion being opposite the first end portion. The lattice is formed within the foot portion and includes a plurality of members that form an open-mesh frame that defines a plurality of voids between adjacent members of the frame. The elastomeric foot is formed of an elastomer and is disposed about the lattice and within the voids of the lattice. The foot is configured to engage a surface to support the body relative to the surface.

First claim

What is claimed:

1. A flask stand configured to support a flask, the flask stand comprising:
a base ring configured to support a lower portion of the flask; and
a plurality of legs, each leg secured to the base ring and extending outward from the base ring, each leg comprising:
a body having a first end portion secured the base ring and a foot portion opposite the first end portion;
a lattice formed within the foot portion, the lattice including a plurality of members that form an open-mesh frame defining a plurality of voids between adjacent members of the frame; and
an elastomeric foot formed of an elastomer disposed about the lattice and within the voids of the lattice, the elastomeric foot configured to engage a surface to support the body relative to the surface.

2. The flask stand according to claim 1 , wherein the first end portion includes an attachment tab, the attachment tab secured the leg to the base ring.

3. The flask stand according to claim 1 , wherein the plurality of legs includes four legs.

4. The flask stand according to claim 1 , wherein the body and lattice of each leg is monolithically formed with one another.

5. The flask stand according to claim 1 , wherein each void of the plurality of voids sized in a range of 0.05 mm to 5 mm.

6. The flask stand according to claim 1 , wherein the elastomeric section comprises a thermoset elastomer or a thermoplastic elastomer.

7. The flask stand according to claim 1 , further comprising a plurality of flask arms, each flask arm extending from the base ring and configured to secure the lower portion of the flask to the base ring.

8. A method of manufacturing a flask stand, the method comprising:
positioning a portion of a leg of a flask stand within a cavity of a mold, the leg including a body and a lattice, the portion of the leg within the cavity of the mold including at least the lattice, the lattice including a plurality of members that form an open-mesh frame defining a plurality of voids between adjacent members of the frame; and
flowing an elastomer into the cavity of the mold with the elastomer flowing through the voids of the lattice and about the lattice.

9. The method according to claim 8 , further comprising additively manufacturing the lattice.

10. The method according to claim 8 , further comprising additively manufacturing the body and the lattice as a monolithic structure.

11. The method according to claim 8 , further comprising three-dimensionally printing the body and the lattice.

12. The method according to claim 11 , wherein three-dimensionally printing the lattice includes the lattice comprising a cross-linked cyanate ester or a cross-linked polyurethane.

13. The method according to claim 8 , wherein positioning the portion of the leg within the cavity of the mold includes the plurality of voids being sized in a range of 0.05 mm to 5 mm.

14. The method according to claim 8 , wherein flowing the elastomer into the cavity of the mold occurs without the lattice being surface treated.

15. The method according to claim 8 , wherein flowing the elastomer includes flowing a liquid elastomer.

16. The method according to claim 15 , wherein flowing the liquid elastomer includes flowing a liquid silicone or a liquid perfluoropolyether.

17. The method according to claim 8 , further comprising securing the leg to a base ring.

18. The method according to claim 17 , wherein securing the leg to the base ring includes inserting an attachment tab of the leg into a recess defined in the base ring.

19. A flask stand configured to support a flask, the flask stand comprising:
a base configured to support the flask; and
a support structure configured to support the base above a surface, the support structure including a first support comprising:
a body having a first end portion secured the base and a second end portion opposite the first end portion;
a lattice formed within the second end portion, the lattice including a plurality of members that form an open-mesh frame defining a plurality of voids between adjacent members of the frame; and
an elastomeric foot formed of an elastomer disposed about the lattice and within the voids of the lattice, the elastomeric foot configured to engage a surface to support the body relative to the surface.

20. The flask stand according to claim 19 , wherein the support structure includes a second support.
