Title: Fixture for securing an umbrella to a chair

Description:
FIELD OF THE INVENTION  
      This invention relates to a fixture for securing an umbrella to a chair.  
     BACKGROUND OF THE INVENTION  
      An umbrella outdoor chair mostly can be seen at the beach or at the movie shooting area used by the director. The umbrella is secured on the chair by a butterfly nut  91  and a bolt  92  with a pair of clips  93  and  94 , as shown in  FIG. 5 . The clip  93  is connected with a gooseneck pipe  96  coupled with a skeleton  97  of the umbrella on the top end thereof. The gooseneck pipe  96  allows adjusting the skeleton  97  to a desired angel. However, this design is inconvenient and requires a higher cost in manufacture.  
      The inventor has therefore derived the present invention to improve the above-mentioned and many other shortcomings.  
     SUMMARY OF THE INVENTION  
      It is the primary object of the present invention to provide a fixture for securing an umbrella to a chair, which is easy to operate.  
      It is another object of the present invention to provide a fixture for securing an umbrella to a chair, which is inexpensive in manufacture.  
      It is a further object of the present invention to provide a fixture for securing an umbrella to a chair, which is easy to mount and dismount.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
      As shown in  FIGS. 1 and 2 , the present invention comprises a first clip  1 , a second clip  2 , a connector nod  3 , a pulling rod  4 , a cam rod  5 , a pin  6  and a spring  7 .  
      The first clip  1  has an arcuate recess  11  at one side with a notch  111  at one side of the recess  11 . The second clip  2  also has an arcuate recess  21  at one side with a notch  211  at one side of the recess  21 . The first clip  1  has a hole  12  at one side.  
      The connector nod  3  has a spherical socket  31  at one end and a cone-shaped connecting end  32  at the other end. The spherical socket  31  has an opening  311  at the outer end, a notch  313  at one side and a ditch  312  at the opposite side thereof. The notch  313  and the opening  311  are interconnected The ditch  312  extends to the connecting end  32 .  
      The pin  6  is inserted through the spring  7  with its two ends connected with the first clip  1  and the second clip  2 , respectively.  
      The connecting end  32  of the connector nod  3  is inserted into the hole  12  of the first clip  1 . The pulling rod  4  is also inserted through the first clip  1  and the second clip  2  and connected with the cam rod  5 . The cone-shaped connecting end  32  with the ditch  312  is urged to insert into the hole  12  of the first clip  1 .  
      By pulling or pushing the cam rod  5 , as shown in  FIGS. 2 and 4 , the pulling rod  4  links the first clip  1  and the second clip  2  to clamp a chair frame,  81 , which brings the opening  311  and the notch  313  of the spherical socket  31  to clamp an umbrella rod  82 . The connecting end  32  can be spun in the hole  12  of the first clip  1 , which links the spherical socket  31  to spin simultaneously and brings the opening  311  to adjust the angle of the umbrella rod  82 . This enables the umbrella rod  82  adjustable both in direction and angle by adjusting the spherical socket  31 . When the cam rod  5  is released to loosen the pulling rod  4 , as shown in  FIG. 3 , the first clip  1  and the second clip  2  are urged by the spring  7  to disengage the chair frame  81  and dismount the umbrella rod  82 .
