Abstract
Official abstract text for this publication.
A finger joint driving device includes a first base portion that is mounted on an index finger, a pressure sensor that is provided between the first base portion and the index finger when the first base portion is mounted on the index finger, and a contact portion that is provided between the pressure sensor and the index finger and comes in contact with the pressure sensor in the mounted state. In addition, durometer hardness of the contact portion which is measured based on JIS K 6253 is equal to or greater than 50.
First claim
Opening claim text (preview).
What is claimed is: 1. A finger joint driving device configured for use on a finger, the finger joint driving device comprising: a finger mounting portion that is configured to be mounted on the finger; a force detection unit that is configured to be provided between the finger mounting portion and the finger when the finger mounting portion is mounted on the finger; and a contact portion that is configured to be provided between the force detection unit and the finger and comes in contact with the force detection unit when the finger mounting portion is mounted on the finger, wherein durometer hardness of the contact portion which is measured based on JIS K 6253 is equal to or greater than 50. 2. The finger joint driving device according to claim 1 , wherein Rockwell hardness of the contact portion which is measured based on JIS K 7202 is equal to or greater than 80. 3. The finger joint driving device according to claim 1 , wherein at least one of the contact portion and the finger mounting portion includes a convex portion projected to the force detection unit. 4. The finger joint driving device according to claim 3 , wherein the convex portion has a curved surface which is curved toward the force detection unit. 5. The finger joint driving device according to claim 1 , wherein the contact portion is formed into a plate shape which is curved toward one direction. 6. The finger joint driving device according to claim 1 , wherein the force detection unit and the contact portion are configured to be positioned on a back of a hand of the finger in the mounted state. 7. The finger joint driving device according to claim 1 , wherein the finger mounting portion includes a finger mounting portion main body that is configured to be positioned on a back of a hand of the finger and a fixing portion that is configured to be positioned on a palm of the hand of the finger to fix the finger mounting portion main body to the finger when the finger mounting portion is mounted on the finger. 8. The finger joint driving device according to claim 7 , further comprising another force detection unit and another contact portion such that there are a pair of the force detection units and a pair of the contact portions, wherein the pair of the force detection units and the pair of the contact portions are configured to be provided via the finger when the finger mounting portion is mounted on the finger, and wherein one of the force detection units and one of the contact portions are provided on a finger mounting portion main body side, and the other of the force detection units and the other of the contact portions are provided on a fixing portion side.
