Abstract

A cup holding apparatus and a serving robot including the cup holding apparatus are provided. The cup holding apparatus may include a first support member configured to support a cup and having a lower surface that has convex shape; a second support member having an upper surface that has a concave shape and faces the lower surface of the first support member; a third plate provided between the first support member and the second support member; and a plurality of rolling members that pass through and are rotatably supported by the third plate, and contact the lower surface of the first support member and the upper surface of the second support member.

First claim

What is claimed is:

1. A cup holding apparatus comprising:
a first support member configured to support a cup and having a lower surface that has convex shape;
a second support member having an upper surface that has a concave shape and faces the lower surface of the first support member;
a third plate provided between the first support member and the second support member, wherein the third plate comprises a first central hole;
a block member that protrudes toward the second support member from the lower surface of the first support member and is disposed in the first central hole; and
a plurality of rolling members that pass through and are rotatably supported by the third plate, and contact the lower surface of the first support member and the upper surface of the second support member,
wherein the block member is configured not to contact an inner circumferential of the first central hole of the third plate when the first support member is not displaced relative to a center of the second support member, and
wherein the block member is configured to contact the inner circumferential surface of the first central hole of the third plate when the first support member is displaced relative to the center of the second support member by a certain amount.

2. The cup holding apparatus of claim 1 , wherein the block member has a cylindrical shape.

3. The cup holding apparatus of claim 1 , wherein an outside diameter of the block member is smaller than an inside diameter of the first central hole.

4. The cup holding apparatus of claim 1 , wherein the second support member comprises a second central hole, and
wherein the block member passes through the first central hole and is disposed in the second central hole.

5. The cup holding apparatus of claim 4 , wherein the block member comprises a third central hole configured to surround a lower region of the cup and support a lower surface of the cup.

6. The cup holding apparatus of claim 1 , wherein the plurality of rolling members are disposed along a circumferential direction of the third plate.

7. The cup holding apparatus of claim 1 , wherein the third plate has a cylindrical shape.

8. The cup holding apparatus of claim 1 , wherein the second support member comprises a sidewall that surrounds the upper surface of the second support member and extends to a level that is higher than the upper surface of the second support member.

9. The cup holding apparatus of claim 1 , wherein the first support member comprises a holder configured to surround a lower region of the cup.

10. A serving robot apparatus comprising:
a main body;
a driving device configured to move the main body;
a cup holding apparatus horizontally supported by the main body,
wherein the cup holding apparatus comprises:
a first support member configured to support a cup and having a lower surface that has convex shape;
a second support member having an upper surface that has a concave shape and faces the lower surface of the first support member;
a third plate provided between the first support member and the second support member, wherein the third plate comprises a first central hole;
a block member that protrudes toward the second support member from the lower surface of the first support member and is disposed in the first central hole; and
a plurality of rolling members that pass through and are rotatably supported by the third plate, and contact the lower surface of the first support member and the upper surface of the second support member,
wherein the block member is configured not to contact an inner circumferential surface of the first central hole of the third plate when the first support member is not displaced relative to a center of the second support member, and
wherein the block member is configured to contact the inner circumferential surface of the first central hole of the third plate when the first support member is displaced relative to the center of the second support member by a certain amount.

11. The serving robot apparatus of claim 10 , wherein the block member has a cylindrical shape, and an outside diameter of the block member is smaller than an inside diameter of the first central hole.

12. The serving robot apparatus of claim 10 , wherein the second support member comprises a second central hole, and
wherein the block member passes through the first central hole and is disposed in the second central hole.

13. The serving robot apparatus of claim 12 , wherein the block member comprises a third central hole configured to surround a lower region of the cup and support a lower surface of the cup.

14. The serving robot apparatus of claim 10 , wherein the plurality of rolling members are disposed along a circumferential direction of the third plate.

15. The serving robot apparatus of claim 10 , wherein the third plate has a cylindrical shape.

16. The serving robot apparatus of claim 10 , wherein the second support member comprises a sidewall that surrounds the upper surface of the second support member and extends to a level that is higher than the upper surface of the second support member.

17. The serving robot apparatus of claim 10 , wherein the first support member comprises a holder configured to surround a lower region of the cup.
