Title: Deck chair

Description:
BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      The present invention relates to a chair and more particularly, to a deck chair that can selectively be set in different positions for different purposes, or set in a received condition to reduce space occupation when not in use.  
      2. Description of the Related Art  
      In order to save storage space, a chair may be made folding collapsible. A commercial folding chair is known comprising a horizontal seat frame, a vertical back frame fixedly provided at the rear side of the seat frame, and two leg members pivotally arranged in a crossed status and respectively pivotally connected to the bottom side of the seat frame. This design of folding chair still occupies much storage space when collapsed because the vertical back frame and the horizontal seat frame are fixedly fastened together and not adjustable relative to each other.  
      There are also known commercial deck chairs that can selectively be set in different positions for different applications. However, these conventional deck chairs occupy much storage space when received.  
     SUMMARY OF THE INVENTION  
      The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a deck chair that can be set in a received condition to reduce space occupation when not in use. It is another object of the present invention to provide a deck chair that can selectively be set in different positions for different applications. To achieve these and other objects of the present invention, the deck chair comprises a base frame, a seat frame horizontally affixed to the base frame at the top, a head frame pivoted to the seat frame and selectively positioned in one of a series of angular positions, a first extension pivoted to the seat frame opposite to the head frame and selectively positioned in one of a series of angular positions, a second extension frame pivoted to the first extension frame opposite to the seat frame and selectively positioned in one of a series of angular positions, and a soft mattress covering the head frame, the seat frame and the extension frames.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
      Referring to  FIG. 1 , the frame structure of a deck chair in accordance with the present invention is shown comprising a base frame  10 , which is an open frame, a seat frame  20 , which is a rectangular open frame fixedly connected in parallel to the base frame  10  at the top, a head frame  30 , which is a rectangular open frame, a joint  31 , which connects the head frame  30  to one side of the seat frame  20 , allowing the head frame  30  to be turned relative to the seat frame  20  and positioned in one of a series of angular positions, and an extension frame unit  40  provided at one side of the seat frame  20  opposite to the head frame  30 . The extension frame unit  40  comprises two extension frames  41 , and two joints  42  that connect a first one of the two extension frames  41  to one side of the seat frame  20  opposite to the head frame  30  and the second one of the two extension frames  41  to one side of the first one of the two extension frames  41  opposite to the seat frame  20 , allowing the extension frame unit  40  to be turned relative to the seat frame  20  and positioned in one of a series of angular positions and the second one of the two extension frames  41  to be turned relative to the first one of the two extension frames  41  and positioned in one of a series of angular positions.  
      Referring to FIGS.  2 ˜ 4  and  FIG. 1  again, a soft mattress  50  is fastened to the frame structure of the deck chair, keeping the seat frame  20 , the head frame  30  and the extension frame unit  40  embedded in the soft mattress  50 .  
      Referring to FIGS.  2 ˜ 4  again, when installed, the user can turn the head frame  30  and the extension frames  41  relative to one another and relative to the seat frame  20  to change the shape of the soft mattress  50 .  FIG. 2  shows the deck chair set in a received status to reduce the storage space.  FIG. 3  shows the deck chair set in a condition for enabling a person to sit thereon with the legs rested on the soft mattress  50  in an extended status.  FIG. 4  shows the soft mattress  50  set in the fully extended horizontal position for enabling a person to sleep thereon.  
      Although a particular embodiment of the invention had been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention.
