Abstract:
1. A joint structure for aluminum windows comprising: a first vertical frame plate having a first inner side integrally formed with two lateral sides extending inwardly from two ends of said first inner side, a first inverted V-shaped longitudinal sliding guide on an intermediate portion of said first inner side, and two first joint members being symmetrically arranged on either side of said first inverted V-shaped longitudinal sliding guide, each of said first joint members comprising two first V-shaped arms extending from said first inner side such that a free end of each of the arms defines a longitudinal opening therebetween for providing resiliency for said first V-shaped arms; a second vertical frame plate having a second inner side integrally formed with two lateral sides extending inwardly from two ends of said second inner side, a second inverted V-shaped longitudinal sliding guide on an intermediate portion of said second inner side, and two second joint members being symmetrically arranged on either side of said second inverted V-shaped longitudinal sliding guide, each of said second joint members having two second V-shaped arms extending from said second inner side such that a free end of each of the arms defines a longitudinal opening for providing resiliency for said second V-shaped arms; and a joint plate having two sides, each side provided with a Y-shaped longitudinal sliding rail at an intermediate portion and two third joint members each arranged on one side of said Y-shaped longitudinal sliding rail, each of said Y-shaped longitudinal sliding rails having an outer side defined by a longitudinal V-shaped recess to receive said inverted V-shaped longitudinal sliding guides of said first and second vertical frames, respectively, and each of said two third joint members being symmetrically arranged on either side of said Y-shaped longitudinal sliding rail to join with said first and second joint members, respectively.
