Title: Takedown structure for game

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to takedown structures and more particularly to a takedown structure for a 3×3 grid game. 
     2. Description of Related Art 
     A conventional structure for a 3×3 grid game is disadvantageous because it is not capable of being taken apart. Its storage or transport is difficult. 
     Thus, the need for improvement still exists. 
     SUMMARY OF THE INVENTION 
     It is therefore one object of the invention to provide a takedown structure comprising a plurality of tubular frame members having a rectangular cross-section, each tubular frame member including two grooves on top and bottom surfaces respectively; a plurality of different fitting members, each fitting member including a parallelepiped body and a plurality of arms, each arm including an axial hole and a plurality of main sections, each main section having a tapered portion wherein each arm is configured to frictionally dispose in an end of the frame member; and a plurality of rectangular boards, each rectangular board including two projections on top and bottom edges respectively, each projection being configured to complimentarily dispose in the groove, and a digit formed on an outer surface of the rectangular board. 
     The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to  FIGS. 1 to 7 , a takedown structure for game in accordance with the invention comprises the following components as discussed in detail below. 
     A plurality of vertical and horizontal tubular frame members  10  having a square cross-section are shown. Each frame member  10  includes two elongated grooves  11  on top and bottom surfaces respectively. 
     A plurality of (five) different fitting members  20  are provided (see  FIGS. 1 and 3 ). Each fitting member  20  includes a parallelepiped body  21  and two, three, or four arms  22 . Each arm  22  includes a plurality of main sections  221  having a tapered portion  222 , and a hole  223  through the main sections  221  and the tapered portions  222 . Except the main section  221  at an open end, the tapered portion  222  of any main section  221  is formed with the adjacent main section  221 . In short, the uneven outer surface of the arm  20  can increase dry friction. Thus, the arm  22  can be frictionally disposed in an end of the frame member  10  to fasten the fitting member  20  and the frame member  10  together. 
     A plurality of square boards  30  having two elongated projections  31  on top and bottom edges respectively are provided. The projection  31  is complimentarily disposed in the groove  11  to fasten the frame member  10  and the square board  30  together. A digit (e.g., 1, 2, 3, 4, 5, 6, 7, 8, or 9) is formed on an outer surface of the square board  30 . 
     Preferably, the frame members  10  are made of aluminum or plastic. 
     Preferably, the fitting members  20  are made of aluminum or plastic. 
     A first embodiment of the fitting member  20  is shaped as cross (see  FIG. 2 ). 
     A second embodiment of the fitting member  20  is shaped as T (see top right of  FIG. 1 ). 
     A third embodiment of the fitting member  20  is shaped as “7” (see  FIG. 3 ). 
     Advantageously, the assembly or disassembly of the invention can be done easily without tools. Further, its storage space is greatly decreased for ease of storage or transport after being taken apart. 
     An individual may throw a ball  40  toward one of the square boards  30  when playing a 3×3 grid game (see  FIG. 7 ). 
     While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
