CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This is a National Stage Application of International Patent Application No. PCT/TR2006/000018, with an international filing date of May 4, 2006, the contents of which are incorporated herein by reference. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to the field of advertisement displays, and particularly to a frame for displaying advertisement posters that provides savings in manufacturing and labor costs, owing to its being manufactured in one stage as a single part by means of injection molding, and to the method for manufacturing the same. 
         [0004]    2. Description of the Related Art 
         [0005]    Aluminum frames are used for the exhibition of advertisement posters in interior spaces. Aluminum frames generally comprise lower aluminum profiles, upper aluminum profiles, background (polystyrene), springs, corner connection elements and PVC protection elements. 
         [0006]    Aluminum frames are manufactured in 5 preparatory stages and 5 assembly stages. Preparatory stages comprise the following:
       cutting the springs in the form of strips with the special machines to sizes suitable for the frame,   manufacturing the lower and upper aluminum profiles by aluminum extrusion method, cutting these profiles in necessary sizes, joining the lower and upper profiles by means of springs and cutting the profiles at 45° angles,   providing the background (polystyrene) and cutting the same into necessary sizes,   cutting and boring metal pieces provided with suitable hardness for the corner connections in press and molding machines, threading holes, coating the same, and screwing together once the corner connections have been made, and   manufacturing PVC protection elements, cutting the same to required dimensions, and opening a canal on one side of PVC to facilitate the opening of the frame from the interior.       
 
         [0012]    Assembly stages comprise the following:
       after the lower and upper aluminum profiles have been drilled, the corner connection elements are attached to two reciprocal edges and the screws and the screw blank spaces are removed;   joining one of the edges, to which the corner connection elements have been attached, to the other two edges by means of the corner connection elements (edges take the shape of U);   applying the background (polystyrene) through the canals located on the lower profile on the edges that have taken a U-shape;   once the background (polystyrene) has been fixed, mounting it on the other U shaped edges by means of corner connection elements; and   placing the PVC protection element at the position delimited by the lower profile, whereby the frame is made ready for the end user.       
 
         [0018]    Because the number of parts in the frame body comprised of the lower aluminum profiles, corner connection elements enabling the assembly of the edges, the background, and the polystyrene layer forming the background is relatively high, the assembly and labor costs are high. In addition, aluminum profiles are produced using the extrusion method, which is similarly time consuming. 
         [0019]    Moreover, various hanger elements are attached to the background, in order to enable the frames to be suspended from a location. This leads to extra costs, and makes the production stages even more difficult. Due to the attachment of the hanger elements to the frame, the frame has a certain clearance from the wall, which often constitutes a problem. 
         [0020]    Accordingly, there is the need for a new frame, which enables the production in a single step without the use of the lower aluminum profiles, corner connection elements and the background to comprise the frame body, and hence provides savings of the manufacturing costs. 
       BRIEF SUMMARY OF THE INVENTION 
       [0021]    It is an object of the invention to provide a new frame, which enables the aluminum frames where the advertisement posters are displayed to be manufactured in a shorter time and at a lower cost, and the production method for the frame. 
         [0022]    It is another object of the invention to provide savings in the operating costs by forming a new frame comprising a body made by the plastic injection method and the springs connected to the aluminum profiles placed on the body, without using the lower aluminum profiles, corner connection elements and the background. 
         [0023]    It is another object of the invention to provide savings in the manufacturing and labor costs by providing a body formed at a single stage without using the lower aluminum profiles, corner connection elements and the background.
