Support device
A support device for improving the haptics and/or gripping impression of humanoid or android type hands includes an active surface that interacts with parts ( 16, 18, 22 ) of the respective hand to carry out a movement and that has individual stem-like projections. Each projection has a free end face such that the projections at least partially improve the adhesion of at least parts of the hand or a hand protector ( 10 ) to surfaces, particularly smooth or delicate surfaces, that are touched. The respective free end faces ( 26 ) of the projections ( 24 ) are designed such that their adhesion results from acting van der Waals forces between the free end faces ( 26 ) and the touched surface.
1. A support device for improving haptics and/or gripping impressions of humanoid and android hands, comprising:
an active surface interacting with parts of a hand for executing movements and having stem-shaped projections extending from a backing with widen head parts on ends of said projections remote from said backing, each said projection having a convex part turning into a concave part in a vicinity of a foot part of each said projection in a transition area into said backing in longitudinal section and in a direction proceeding from said head part to said foot part of each said projection; and
free end faces of said head parts at least partially improving adhesion of at least parts of a hand or hand projection to engaged surfaces that are at least one of especially smooth and delicate when touched, said free end faces being formed to provide van der Waals forces between said free end faces and the engaged surfaces.
2. A support device according to claim 1 wherein
at least said end faces are formed of a water-repellant material adhering without residue.
3. A support device according to claim 2 wherein
said water-repellant material comprises polyvinyl siloxane.
4. A support device according to claim 1 wherein
each said end face has a contact surface adjoining the engaged surfaces.
5. A support device according to claim 1 wherein
said projections are arranged at least one of regularly and irregularly on said backing with a surface density of 10,000 to 60,000 projections per square centimeter of a surface of said backing.
6. A support device according to claim 5 wherein
said surface density is 20,000 to 45,000 projections per square centimeter.
7. A support device according to claim 6 wherein
said surface density is approximately 30,000 projections per square centimeter.
8. A support device according to claim 1 wherein
said projections integrally adjoin said backing.
9. A support device according to claim 1 wherein
said projections are formed on parts of at least one of a hand protection.
10. A support device according to claim 1 wherein
said backing comprises a film.
11. A support device according to claim 10 wherein
said film is joined to parts of one of a hand and a hand protection by an adhesive bond.
12. A support device according to claim 10 wherein
pieces of said film are arranged on selective regions of one of a hand and a hand protection and isolated from one another.
13. A support device according to claim 12 wherein
at least one of said pieces of said film are located in each fingertip region on an inside of one of said hand and said hand protection.
14. A support device according to claim 12 wherein
at least one of said pieces of said film are on a palm of the hand.
15. A support device according to claim 14 wherein
said at least one of said pieces of said film is in a region of a ball of a thumb.
16. A support device according to claim 12 wherein
at least one of said pieces of said film is on a back of the hand protection.
17. A support device according to claim 16 wherein
said at least one of said pieces of said film is in a region of fingers.
18. A support device according to claim 10 wherein
said film forms all of a glove for a humanoid hand.
19. A support device according to claim 18 wherein
said film is formed into said glove by blow molding.
