摘要:
This nursing bed has a fixed member (13A) forming a fixed bed surface of a bed portion (3) on which a care receiver (P) lies, a movable member (13B) which can be moved relative to the fixed member (13A) and forms a movable bed surface of the bed portion (3), and a movable member driving unit (5) for driving the movable member (13B). The fixed member (13A) has a plurality of slender parts each extending in the lateral direction or the longitudinal direction. The movable member (13B) has a mobile body (13B) which can be protruded upward relative to the fixed bed surface and also moved in at least one of the longitudinal direction and the lateral direction via an interval between the plurality of slender parts by the movable member driving unit (5). The posture of the care receiver lying on the bed can be changed into his/her optimal position without difficulty.
摘要:
To provide a nursing bed capable of preventing bedsores of a care receiver while minimizing a burden on the body of the care receiver when changing posture. A nursing bed 1 with a longitudinal dimension L and a width dimension W has an upper surface forming member 3 which forms a bed upper surface 2 on which a care receiver lies and a driving mechanism 6, 7 configured to move at least a portion of the upper surface forming member 3. The bed upper surface 2 includes a curved surface which is curved downwardly in the width direction.

A robot comprises a robot arm including a lower arm (20), an upper arm (30) and a hand (40) attached to the tip end portion of the upper arm such that the hand is rotatable around a rotational axis (L3) thereof; a lower arm drive unit (15) which drive the lower arm to move the hand, an upper arm drive unit (25) which drives the upper arm to move the hand; a hand drive unit (35) which rotates the hand; a hand angular position detecting section (37) which detects an angular position of the hand around the rotational axis (L3); and a control unit which controls the upper arm drive unit, the lower arm drive unit, and the hand drive unit, wherein the hand includes a blade (40b) having a first contact/slide surface (50a) and a second contact/slide surface (50b) which extend in a first direction, contact a teaching target (T) and slide thereon, and the first contact/slide surface and the second contact/slide surface include a first characterizing portion (51a) and a second characterizing portion (51b) having bent points in the first direction, respectively.
摘要:
The present invention relates to an end effector device 1 attached to a tip end portion of a robot arm, and the end effector device 1 includes a plurality of support units 3 provided on a blade 10. Each of the support units 3 includes: a plurality of nail pieces 30 configured to support peripheral portions of a plurality of semiconductor wafers 9 such that the semiconductor wafers 9 are parallel to one another and spaced apart from one another; and a pitch changing mechanism 4 configured to change upper-lower intervals of the nail pieces 30. The pitch changing mechanism 4 includes: a coil spring 40 configured to support the plurality of nail pieces 30 such that the plurality of nail pieces 30 are spaced apart from one another in an upper-lower direction and elastically deform in the upper-lower direction; and an operating mechanism 5 configured to cause the coil spring 40 to elastically deform in the upper-lower direction. The operating mechanism 5 includes a piston pin 50 fitted in the coil spring 40 to move up and down.
