BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a partial structure of a barbell hanger, and more particularly to an innovative improved structure revealer, which is used for a barbell hanger
2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.
In the actual application of a barbell hanger, the structural type design of the barbell hanger is generally accepted because the barbell with considerable weight must be firmly supported. Not only does the hanger mostly adopt the massive hollow metal tube, but also the bottom end of both left and right sides of the tube is usually fixed on the floor through a bolt lock assembly.
In the design of the existing barbell hanger structure, the top ends of the two adjacent vertical tubes are usually connected through the lateral frame rods, so as to form a relatively stable frame structure. The arrangement of these lateral frame rods usually uses a reasonable length as the size specification of one unit; however, the problem with the conventional barbell hanger application is often when the overall structure needs to be extended and expanded. When the span between the two adjacent vertical tubes needs to be enlarged, though the lateral frame rod part can be extended in its lateral length through the joint combination, but the joint combination part will be bended in the future due to insufficient structural strength, which in turn causes problems in the durability of the barbell hanger.
