  "claims": [
    "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.",
    "2. The joint structure for aluminum windows as claimed in claim 1, wherein an outer end of said lateral sides of said first and second vertical frames is formed with an inwardly extending edge.",
    "3. The joint structure for aluminum windows as claimed in claim 1, wherein said joint plate has two outer ends each provided with an accommodating groove.",
    "4. The joint structure for aluminum windows as claimed in claim 3, further comprising a leak proof rubber fitted in said accommodating groove."

  "description_excerpt": "FIG. 1 illustrates an assembly of two conventional aluminum windows. FIG. 2 illustrates an assembly of four conventional aluminum windows. As shown, it mainly joints the glass frames 20 with the window frames 10 inwardly. While in practical application, this kind of aluminum windows often are set by adopting the forms of side by side or top-down-left-right similar as the glass window curtain. And, the ordinary joint assembling method is to further form a joint bar plate 13 on the vertical frame plate 110 and horizontal frame plate 12 of the window frame 10. While the window frames 10 are left-right side by side assembled, an out laid vertical joint frame plate 30 is formed by jointing the joint bars 13 on the vertical frame plates 110 of these two window frames 10 as a whole. While the window frames 10 adopt the top-down joint assembling, a horizontal joint frame plate 40 is used by jointing the joint bars 13 on the horizontal vertical frame plates 12 of these two window frames 10 together as a whole. Such set up not only requires the extra joint bar 13, but have also the larger volume in the said vertical and horizontal joint frame plates 30, 40. Relatively, the used aluminum material becomes more thus increases the cost. At the same time, because the out laid joint method in the said vertical and horizontal joint plates 30, 40 is adopted, a complex sense of disorder has been created in the whole outside appearance of frames after assembling. This kind of assembling design is thus not an ideal one.",
