Description

Hinge and door frame connection structure

The invention relates to a structure in which an outer frame and a door panel are pivotally connected, in particular to a bottom joint of two adjacent door frames by a hinge and hidden, so as to exert an optimal pivoting force effect and maintain an unobstructed view of the glass door.

Referring to FIG. 1 , a conventional multi-piece folding door is provided. A door panel 1 including at least three glass materials is disposed on an outer frame 2 , and upper and lower sides of the outer frame 2 are respectively provided with a horizontal upper rail (not shown). And the lower track 3, the adjacent two of the door panels 1 are pivotally connected by at least one upper hinge 4 and the lower hinge 6 of the upper and lower sides, and the upper hinge 4 is connected with an upper roller 5 to follow the outer frame 2 The upper rail 6 is removed, and the lower hinge 6 is connected to the lower roller 7 to be removed along the lower rail 3, so that the door panels 1 can be rotated and joined to each other along the upper rail and the lower rail 3, and are moved to the outer frame 2. One side reaches the door opening state, or the door panels 1 are pulled open to close the outer frame 2 to the closed state. Because the weight of the door panels 1 is transmitted to the lower rails 3 by the hinges 6 and the lower rollers 7 located under the door panels 1, the lower rails 3 of the outer frame 1 carry the weights of the door panels 1 and The upper hinge 4 is pivotally transmitted to the upper roller 5 and the upper rail, and is erected on the outer frame 2.

Since the multi-piece folding door is mostly made of transparent tempered glass, it has considerable weight, and the weight of the tempered glass plate will fall below the door panel 1, that is, the lower frame of each door panel, but the lower hinge The 6 series is installed at the side frame 8 of the door panel 1, causing the lower hinge 6 not to Carrying the downward gravity of the door panel 1 in the most direct and powerful position, and the upper hinge 4 is pulled and pivoted to the adjacent two door panels 1, but a distance is generated from the top end of the door panels 1 to generate a moment, resulting in two adjacent The upper hinge 4 between the door panels 1 cannot perform the optimal supporting force, and the upper hinge 4 and the lower hinge 6 are installed on the side panel of the door panel 1 and are completely exposed, and the side frame 8 is not only impeded by the aesthetic effect of obstructing the see-through effect. It is necessary to have a considerable width to install the upper and lower hinges 4, 6, and the overall improvement in the perspective of the glass door panel 1 is not aesthetically pleasing.

Accordingly, the main object of the present invention is to provide a hinge and door frame connection structure by pivotally connecting two first hinges of adjacent first and second door frames to upper and lower frames of the first and second door frames, respectively.

The left and right side frames thus reduce the width, which in turn allows the entire glass door to achieve a fluoroscopic aesthetic.

In addition, the two protrusions 711 and 721 disposed adjacent to the second and third door frames 30 and 40 are respectively inserted into the right port of the second upper frame strip 33 and the third upper frame strip 43. In the left port, the two enclosing surfaces 77 disposed adjacent to the second and third door frames 30 and 40 respectively enclose the right port of the second upper frame strip 33 and the left port of the third upper frame strip 43 respectively. Then, the plurality of screws 80 are threaded to make the second left turn piece of the second hinge 70 disposed adjacent to the second and third door frames 30 and 40. 71 and the second right turn 72 are respectively fixed to the right end of the second upper frame strip 33 and the left end of the third upper frame strip 43. The second hinge 60 located adjacent to the second and third door frames 30, 40 is aligned with the second and third upper frame strips 33, 43 to support the second and third door frames 30 at the shortest distance. 40 weights and erected on the outer frame 10 for optimum support.

When the door is closed, the second left rotating member 71 and the second right rotating member 72 disposed adjacent to the upper and lower sides of the second and third door frames 30 and 40 can be hidden, and the second and third door frames 30 and 40 are hidden. The left and right side frames thus reduce the width, which in turn allows the entire glass door to achieve a fluoroscopic aesthetic.

The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are all It is still within the scope of the invention patent.
