Title: Framework structure

Description:
BACKGROUND OF THE INVENTION  
      The present invention is related to a framework structure, including a guide track, a rack body, and locking members wherein the guide track has a guide groove properly indented therein and the rack body is equipped with a plurality of toothed protrusive flanges tilting inwards at both lateral sides thereon to define a retaining space there-between for the guide track to be securely located therein. The locking member is provided with a receiving cavity for holding each end of the coupled guide track and the rack body thereby. In assembly, the mutually engaged guide track and the rack body are cooperatively matched to a screen body, facilitating an easy and speedy opening/closing operation of the screen body thereof. Besides, the coupled guide track and the rack body are capable of being flexibly bent or arched into matched shapes relative to various kinds of the screen body such as a canopy, a mosquito net, or a blind drapery, etc., efficiently achieving widespread use of the framework thereof.  
      Please refer to  FIG. 1 . A conventional framework for a canopy/mosquito net is made up of an integral-made and U-shaped frame body  10 , a patterned decoration article  11  securely fixed at the upper side of the frame body  10  thereon, and a canopy/mosquito net  20  fixedly attached at the underside of the frame body  10  thereof. At one side of the canopy/mosquito net  20  is preset with an opening that is slightly lifted sideways to reveal an exit or entrance in practical use. However, it&#39;s quite inconvenient to go into and out of the canopy/mosquito net  20  through the small area defined by the opening thereof. Besides, the frame body  10  is integrally molded with the patterned decoration article  11  fixedly attached thereto that is unable to be flexibly replaced by a new one as desired. And due to the large volume thereof, the conventional framework tends to occupy a lot of space in the loading and delivery process. Thus, it is not only troublesome to load and deliver the framework thereof but also quite limited in the amount loaded for delivery thereof.  
     SUMMARY OF THE PRESENT INVENTION  
      It is, therefore, the primary purpose of the present invention to provide a framework structure, including a guide track, a rack body, and locking members wherein the guide track having a guide groove defined therein is mutually registered with the rack body, and the coupled guide track and the rack body thereof are capable of being flexibly bent or properly arched into matched shapes relative to various kinds of the screen body such as a canopy, a mosquito net, or a blind drapery, etc., efficiently achieving widespread use of the framework thereof.  
      It is, therefore, the second purpose of the present invention to provide a framework structure wherein the guide track, the rack body, and the locking members thereof are individually made and respectively provided with smaller volume, facilitating an easier and effort-saving loading and delivery process thereof as well as occupying less space to increase the loading amount for delivery thereof.  
      It is, therefore, the third purpose of the present invention to provide a framework structure wherein a patterned decoration article can be detachably locked up onto the framework thereof, and the decoration article can be easily replaced with a new one of different design as desired, or simply omitted in the assembly thereof.  
      It is, therefore, the fourth purpose of the present invention to provide a framework structure wherein sliding units can be mounted to the guide groove of the guide track therein to cooperatively work with the screen body of various kinds so that the screen body can be adjusted to open up and locate at a certain wideness as desired, facilitating the practical use of the framework in an easier way.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
      Please refer to  FIG. 2 . The present invention is related to a framework structure, including a guide track  30 , a rack body  40 , and locking members  50  wherein the guide track  30 , an elongated rectangular plastic body, has a T-shaped guide groove  31  indented at a preset position therein, and the rack body  40 , made of metallic material of a proper thickness to be correspondingly registered with the guide tack  30  thereby, is equipped with a plurality of toothed protrusive flanges  41  correspondingly tilting inwards at both lateral sides thereon to define a retaining space  42  there-between, and a plurality of clamping recesses  43  alternatively arranged among the toothed protrusive flanges  41  thereof. The locking member  50  is provided with a receiving cavity  51  defined at a proper position thereon, and a through hole  52  disposed at a preset position in communication with the receiving cavity  51  thereof.  
      Please refer to FIGS.  3  to  4  inclusive. In assembly, the locking member  50  is securely fixed onto a wall at a proper position thereon, and the guide track  30  is led through the rack body  40  from one side thereof and properly located at the retaining space  42  therein. Via the toothed protrusive flanges  41  correspondingly tilted into a tapered angle at both lateral sides of the rack body  40  thereof, the guide track  30  is precisely clamped tight and limited at the retaining space  41  therein for secure location thereby as shown in  FIG. 4 . The coupled guide track  30  and the rack body  40  are properly arched at preset positions to form a U-shaped framework with both ends thereof bent inwards for a certain length to be respectively registered with the receiving cavity  51  of the locking member  50  thereof and fixedly screwed up thereto via the through hole  52  thereof. A patterned decoration article  60  is properly attached at one side of the coupled guide track  30  and the rack body  40  thereof, and sliding units  70  are mounted at the guide groove  31  of the guide track  30  therein. The sliding unit  70  is provided with a hook  71  for a screen body  72  such as a canopy or a mosquito net to be hanged thereon. In practical use, the screen body  72  of a canopy or a mosquito net is activated by the sliding units  70  to open up and locate at a proper wideness as desired, facilitating a convenient going in or out of the screen body  72  there-through as well as the opening/closing operation thereof in an easy and speedy manner.  
      Please refer to  FIG. 5 . The locking member  50  can also be securely fixed onto a sidewall of a window frame at a proper position thereon, and the guide track  30  engaged with the rack body  40  thereof is bent in matched arch relative to the window frame thereof. The sliding units  70  are then mounted at the guide groove  31  of the guide track  30  therein, and the screen body  72  is hanged onto the hooks  71  thereof to suspend downwards like a window drapery. Both ends of the coupled guide track  30  and rack body  40  are respectively bent into a proper angle and for a certain length to be fixedly screwed up to the receiving cavity  51  of the locking member  50  for location therein.  
      Please refer to  FIG. 6 . The mutually engaged guide track  30  and the rack body  40  can also be bent into a matched square U-shape relative to a window frame and securely mounted thereto via the locking members  50  thereof.  
      Please refer to  FIG. 7 . The coupled guide track  30  and the rack body  40  thereof can also be bent into a U-shaped frame with both arms slantingly expanding outwards in match to a window frame and securely mounted thereto via the locking members  50  thereof.  
      Please refer to  FIG. 8 . The guide track  30  and the rack body  40  thereof can also be formed into a straight line in match to a window frame and securely mounted thereto via the locking members  50  thereof.
