Abstract
The joint device having a linking unit which links a first member and a second member in a manner allowing relative movement, and having an expansion/contraction device 12 which is connected across the first member 1 and the second member in a manner allowing power transmission and which can modify an angle formed by the first member and the second member around the linking member by expanding and contracting. The expansion/contraction device has a rotary unit which generates rotary power, and a conversion unit which is connected to the rotating unit in a manner allowing power transmission and converts the rotary power generated by the rotary unit into translational motion along a direction of expansion/contraction.
Claims13
A joint device comprising
- a linking unit that links a first member with a second member such that the first and second members are movable relative to each other;
- and
- an extension/contraction device that is connected between the first member and the second member in a manner allowing power transmission, and is capable of varying an angle formed by the first member and the second member around the linking unit by extending and contracting,
- wherein the extension/contraction device includes a rotary unit that is configured to generate a rotational power, and a conversion unit that is connected to the rotary unit in a manner allowing power transmission and is configured to convert the rotational power generated by the rotary unit into translational motion in an extension/contraction direction, and includes, between the rotary unit and the conversion unit, a connection/disconnection unit that is capable of connecting and disconnecting power transmission from the rotary unit to the conversion unit, and
- wherein the connection/disconnection unit includes a first connection/disconnection member coupled to a side of the rotary unit and a second connection/disconnection member coupled to a side of the conversion unit, and further includes a first urging part that is configured to contract in an axial direction between the first connection/disconnection member and the second connection/disconnection member, and apply an urging force in a direction in which the first and second connection/disconnection members are constantly spaced apart from each other.
