Structure improvement of the pillow

Abstract

The present invention relates to an “structure improvement of the pillow”, which comprises a central main pillow and two lateral sub-pillows, wherein, said central main pillow is trapezoid in dimension with height of pillow top and central length such that the height of pillow top approximately equals the distance between the outer hind skull surface to the outer surface of the normal arched cervical vertebra when people lies on one's back while the height of central length approximately equals the distance between the outer side surface of two ears of human head with slight clearance for tolerance; said lateral sub-pillow is trapezoid in dimension with height of pillow top and the height of pillow top approximately equals the distance between the outer side skull surface to the outer side surface of the shoulder when people lies on one's side; The characterized is that a pair of symmetrical skew-angled arrangement for said central main pillow and each of said two lateral sub-pillows is formed in disposal so that the user head can be exactly placed on and closely supported by one of the two lateral sub-pillows completely when the user lies on one's side sleeping posture; Besides, a sunken dent space is created on the central top of the lateral sub-pillow so that the user ear will be not pressed without uncomfortable feeling.

1 . An “structure improvement of the pillow” comprises a central main pillow and two lateral sub-pillows, wherein, Said central main pillow has a lateral sub-pillow attached at each of the both lengthwise opposite ends, which is trapezoid in dimension with height of pillow top and central length such that the height of pillow top approximately equals the distance between the outer hind skull surface to the outer surface of the normal arched cervical vertebra when people lies on one's back while the height of central length approximately equals the distance between the outer side surface of two ears of human head with slight clearance for tolerance; Said two lateral sub-pillows, is trapezoid in dimension with height of pillow top and said height of pillow top approximately equals the distance between the outer side skull surface to the outer side surface of the shoulder when people lies on one's side; The characterized is that a pair of symmetrical skew-angled arrangement for said central main pillow and each of said two annexed lateral sub-pillows is formed in disposal such that the integral top view thereof is not in linear array. 
   
   
       2 . The “structure improvement of the pillow” as recited in  claim 1 , wherein, said two lateral sub-pillows is shaped in arched cuboid in feature to have curved joint with the central main pillow in continuous crook manner thereon respectively 
   
   
       3 . The “structure improvement of the pillow” as recited in  claims 1  and  2 , wherein, a strap pulling cord is run therethrough in the central of the lateral sub-pillow with tautness alteration via binding up arbitrarily so that a sunken dent space is created on the central top thereof. 
   
   
       4 . The “structure improvement of the pillow” as recited in  claims 1  and  2 , wherein, said central main pillow and two lateral sub-pillows are further designed into detachably separated independent manner instead of jointed state having a set of plural foldable mats with articulations disposed beneath, wherein, both of the bottom surface of the central main pillow and lateral sub-pillow as well as the top surface of each mat, a Velcro fabric is glued thereon respectively. 
   
   
       5 . The “structure improvement of the pillow” as recited in  claims 1  and  2 , wherein, said central main pillow and each of two lateral sub-pillows is further wrapped by an additional pillowcase respectively. 
   
   
       6 . The “structure improvement of the pillow” as recited in  claim 4 , wherein, said central main pillow, two lateral sub-pillows and mats are able to be stored and packed in a preset collecting bag.
