Document Type and Number:
Japanese Patent JP2015054146
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a mount base swinging device which can achieve smooth swinging and can be used for a bed preventing pressure sore.SOLUTION: A mount base swinging device comprises: a mount base 1; a support body 2 for supporting the mount base 1 at the lower surface center on a floor F; drive arms 55 located in other two points that form a triangle along with the center in a plane view; and guide bodies 4 disposed in the vicinity of these drive arms 55 respectively. The support body 2 includes: an inner member 23 formed with a swollen outer peripheral surface 231 to be a convex spherical surface; and an outer member 24 formed with an inner peripheral surface 241 on a concave spherical surface sliding along the convex spherical surface. In the drive arm 55, one end is swingably connected to a mutually different position in a circumferential direction at both ends of a drive shaft 53, and the other end is swingably connected to the lower surface of the mount base 1. The guide body 4 includes: an inner member 44 formed with a swollen outer spherical surface 441 to be a convex spherical surface; an outer member 43 formed with an inner peripheral surface 431 on a concave spherical surface sliding along the convex spherical surface; and a shaft member 45 which linearly and slidably penetrates through the inner member 44 in a vertical direction.
