Bottom-fixed type rolling pillow

Abstract

A bottom-fixed type rolling pillow, which can continuously maintain a comfortable and correct sleep position of a user by moving the central axis of a cushion member by the movement of a user, is proposed. The bottom-fixed type rolling pillow includes: a base member providing a supporting force while being located on a floor, and having an arcuate-grooved receiving space formed on an upper surface thereof so as to receive a head of a user in the receiving space; a cushion member movably mounted in the receiving space of the base member and configured to support the head of the user; and a cushion moving member movably coupling the cushion member to the base member, and configured to allow the cushion member to be moved by movement of the user.

1 . A bottom-fixed type rolling pillow comprising:
 a base member providing a supporting force while being located on a floor, and having an arcuate-grooved receiving space formed on an upper surface thereof so as to receive a head of a user in the receiving space;   a cushion member movably mounted in the receiving space of the base member and configured to support the head of the user; and   a cushion moving member movably coupling the cushion member to the base member, and configured to allow the cushion member to be moved by movement of the user.   
     
     
         2 . The bottom-fixed type rolling pillow of  claim 1 , wherein the cushion moving member comprises:
 guide rails formed in at least one direction of a longitudinal direction and a transverse direction of an upper surface of the receiving space of the base member so as to provide a moving path of the cushion member;   a slider movably coupled to the guide rails while being fixed to a lower surface of the cushion member and configured to be moved along the guide rails; and   rollers mounted to the upper surface of the base member so as to be idle-rotated and configured to support the slider.   
     
     
         3 . The bottom-fixed type rolling pillow of  claim 2 , wherein the guide rails comprises transverse rails having groove shapes extended along the longitudinal direction of the base member, and
 the rollers have guide wheels which have wheel shapes and are configured to be rotated forward or rearward in directions corresponding to longitudinal directions of the transverse rails so as to move the slider along the transverse rails.   
     
     
         4 . The bottom-fixed type rolling pillow of  claim 2 , wherein the guide rails comprises: transverse rails having groove shapes extended along the longitudinal direction of the base member; and longitudinal rails having groove shapes extended along the transverse direction of the base member and arranged perpendicular to the transverse rails, and
 the rollers have guide balls which have ball shapes and are configured to be rotated forward or rearward in directions corresponding to the transverse rails and the longitudinal rails so as to move the slider along the transverse rails and the longitudinal rails.   
     
     
         5 . The bottom-fixed type rolling pillow of  claim 2 , wherein the cushion moving member further comprises roller brakes configured to selectively allow movement of the slider while selectively restraining rotation of the rollers. 
     
     
         6 . The bottom-fixed type rolling pillow of  claim 5 , wherein the roller brakes comprise pressing protrusions, which are mounted to the base member and configured to be locked to portions of the rollers by pressure of the user to prevent the rollers from being arbitrarily rotated.
