Title: Healthful cushion

Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention: 
   The present invention is related to a healthful cushion and particularly to a healthful cushion with which the interior can be changed depending on different seasons and the user can adjust positions of the magnetic pieces to align with acupuncture points of his/her body. 
   2. Brief Description of Related Art: 
   The conventional cushion is mostly placed on seat part of a chair to offer the user a support with softness different from seat part. However, the traditional cushion generally is filled with a piece of sponge or granular cushion substances so that it is not possible to provide different effects in accordance with weather and seasonal changes. For instance, it is easy to sweat at the hip in the summer time in case of the sponge being used and a uncomfortable cold feeling is experienced at the hip in the winter time in case of the granular cushion substances being used. 
   SUMMARY OF THE INVENTION 
   A main object of the present invention is to provide a healthful cushion with which the interior can be changed depending on different seasons and the user can adjust positions of the magnetic pieces to align with acupuncture points of his/her body. 
   In order to achieve the preceding object, the healthful cushion according the present invention includes:
         an outer shield member, providing six cloth strips being sewed to form a shape of cross with a central section and four outward extending sections, the central section having a plurality of openings and each of the cloth strips having a secure part at both ends thereof for being adhered to each other;   a plastic pad, being attached with a Velcro sheet, providing a plurality of magnetic pieces and each of the magnetic pieces being covered with a net cloth at the upper side thereof;   a first cushion member, being a quadrilateral bag corresponding to the central section of the outer shield member with zippers being attached to the periphery thereof and crystals being stuffed inside thereof; and   a second cushion member, providing the same configuration as the first cushion member with soft stuff inside.       

   Hence, the first cushion member and the second cushion member can be changed positions each other by the user depending on the weather to reach the purpose of warmness in the winter and coolness in the summer.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
   Referring to  FIGS. 1 to 3 , a healthful cushion according to the present invention includes following parts. 
   An outer shield member  10 , which has six cloth strip members  11  constituting a cross structure with four extending outward sections by way of crossing sewing. Each of the cloth strip members  11  provides a secure part  12  at both ends thereof and it is preferable that the secure part  12  is made of Velcro. Of course, the secure part  12  at both ends of the respective cloth strip member  11  can be a button and a buttonhole respectively instead. The outer shield member  10  has a plurality of openings  100  and in order to locate the cloth strip members  11 , buttons  110  can be provided on the cloth strip member  11 . 
   A plastic pad  13 , which provides a Velcro sheet  130  and a plurality of magnetic pieces  33  corresponding to the openings  100  of the outer shield member  10 , in which each of the magnetic pieces  33  is covered with a net cloth  131  at the upper side thereof. 
   A first cushion member  20 , which is a quadrilateral bag corresponding to the central position of the cross shape structure of the shield member  10 . The first cushion member  20  provides zippers  21  at the periphery thereof and is stuffed with crystal granules  22 . 
   A second cushion member  30 , which provides the same configuration as the first cushion member  20  and zippers  31  are disposed at the periphery thereof with soft stuff inside. It is preferable that the soft stuff is infrared fiber polyester foam. 
   Referring to  FIG. 3  again, the first cushion member  20  is placed above the second cushion member  30  during the summer time. Then, the plastic pad  13  and the outer shield member  10  are placed on the first cushion member  20  sequentially. Finally, the first and second cushion members  20 ,  30  are wrapped with the four extending outward sections of the outer shield member  10  and the secure part  12  at both ends of the respective cloth strip member  11  engage with each other at the bottom of the second cushion member  30 . While in use, the user sits on the outer shield member  10 , which encloses the second cushion member  30  and the first cushion member  20 , and experiences the feeling of softness and warmness. Further, the blood circulation of the user can be promoted with the infrared polyester foam stuffed in the second cushion member to remove fatigue effectively. 
   Referring to  FIGS. 4 and 5 , the second cushion member  20  is placed above the first cushion member  30  during the wintertime. Then, the plastic pad  13  and the outer shield member  10  are placed on the first cushion member  20  sequentially. Finally, the first and second cushion members  20 ,  30  are wrapped with the four extending outward sections of the outer shield member  10  and the secure part  12  at both ends of the respective cloth strip member  11  engage with each other at the bottom of the second cushion member  30 . While in use, the user sits on the outer shield member  10 , which encloses the first cushion member  20  and the second cushion member  30 , and experiences the feeling of the crystal granules pressing his/her hip and well ventilated comfort. 
   Referring to  FIG. 6 , it can be seen that the healthful cushion of the present invention can be placed on the car chair directly. Hence, it is can be used conveniently and easily. 
   While the invention has been described with referencing to preferred embodiments thereof, it is to be understood that modifications or variations may be easily made without departing from the spirit of this invention, which is defined by the appended claims.
