Height Adjustable Pillow

Abstract

The invention is a pillow that comprises the first pillow section, at least one height adjustment unit, and a pedestal. The first pillow section is for a user to rest his/her head on. The height adjustment unit includes an elevator unit which connects to the first pillow section, and a support unit to work with the elevator unit as the control of the up/down movement of the first pillow section. The pedestal connects to the support unit of the height adjustment unit. The space above the pedestal and underneath the first pillow section defines the resting space for a user to rest his/her hands and arms. Adjusting the pillow to a proper height via the height adjustment unit, a user can rest his/her head on the pillow and allow his/her spine to maintain in a horizontal position to prevent any spinal curvature.

1 . A pillow which comprises:
 a) The first pillow section for a user to rest his/her head;   b) At least one height adjustment unit comprising an elevator unit which connects to the first pillow section, and a support unit to work with the elevator unit as the control of the up and down movement of the first pillow section; and   c) The pedestal which connects to the support unit of the height adjustment unit where the space above the pedestal and underneath the first pillow section defines the resting space for a user to rest his/her hands and arms.   
     
     
         2 . The pillow of  claim 1 , wherein said elevator unit in said at least one height adjustment unit comprises a first iron bracket that connects to the lower side of the first pillow section, a first shell to cover the first iron bracket, and a first wave board and a vertical first hollow slot in the portion of the iron bracket that is not connected to the first pillow section. 
     
     
         3 . The pillow of  claim 2 , wherein said support unit in said at least one height adjustment unit comprises of a second iron bracket that connects to the upper side of the pedestal and touches the first iron bracket to allow concurrent movement of the first iron bracket and first shell, a second shell that covers the second iron bracket and partially covered by the first shell, a second wave board that corresponds to and overlaps with the first wave board, and a second hollow slot that opposites to the first hollow slot. 
     
     
         4 . The pillow of  claim 3 , wherein said at least one height adjustment unit comprises of a bolt that serves as the user-controlled knob, and a fastening piece connecting to the bolt where the bolt enters from outside of the first and second hollow slots, penetrates the first and second wave boards, and protrudes the second wave board to connect to the fastening piece. 
     
     
         5 . The pillow of  claim 4 , further comprises a second pillow section placed above pedestal and adjacent to at least a height adjustment unit. 
     
     
         6 . The pillow of  claim 5 , where the height of both sides of the second pillow section is lower than the lowest side of the first pillow section. 
     
     
         7 . The pillow of  claim 6 , further comprises a third pillow section and another height adjustment unit that connects the third pillow section and the upper end of the pedestal, to render the third pillow section, along with its height adjustment unit, jointly adjacent to the second pillow section. 
     
     
         8 . The pillow of  claim 4 , where at least one height adjustment unit is connected to the bottom of each of the two broader sides of the first pillow section, and the bottom of each height adjustment unit connects to the pedestal with the two arches of the pedestal facing each other to form an arm-resting space. 
     
     
         9 . The pillow of  claim 8 , where the number of height adjustment unit is four with each height adjustment unit separately connects to the four corners under the first pillow section, and each height adjustment unit either connects separately to each pedestal, or two height adjustment units at each side connect together to the same pedestal. 
     
     
         10 . The pillow of  claim 8 , where the number of height adjustment unit is three with two of the three height adjustment units separately connect to the front and back corners underneath one broader side of the first pillow section and another height adjustment unit connects to the middle portion underneath the other broader side of the first pillow section, and the bottom of each height adjustment unit individually connects to the pedestal.
