DETAILED DESCRIPTION OF THE INVENTION

In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.

Referring to FIGS. 1 to 4, the structure of the present invention is illustrated. The present invention has the following elements.

A frame substrate 1 is fixed to an outer frame of a window.

A window substrate 2 is fixed to an upper and a lower window frame.

A first driven unit 3 and a second driven unit 4 are connected between the frame substrate 1 and the window substrate 2.

A pivotal unit 51 is connected at a pivotal portion of the first driven unit 3 and the window substrate 2 and has a supporting block 511 at a lower end thereof.

Referring to FIG. 5, a first protrusion 11 and a second protrusion 12 are installed on the frame substrate 1. The frame substrate 1 is formed with a plurality of retaining holes 13. The first protrusion 11 is formed with a second pivotal hole 111. One end of the first driven unit 3 is positioned to the frame substrate 1 by using a pivotal joint 52 to pass through the pivotal hole 111 of the first protrusion 11 and a hole in the first driven unit 3. The second protrusion 12 has a pivotal hole 121. One end of the second driven unit 4 is pivotally connected to the frame substrate 1 by using a pivotal joint 54.

The first protrusion 11 has a first pivotal hole 110 aside the second pivotal hole 111 for installing a limiting block 112 which is used to limit the first driven unit 3 to a full open limiting position and limiting the second driven unit 4 to a close limiting position. Referring to FIG. 10, the limiting block 112 has a large upper portion and a small lower portion. The large upper portion serves for limiting an elevation as the second driven unit 4 closes. The small lower portion of the limiting block 112 passes through the first pivotal hole 110 of the first protrusion 11 to engage to a ring 1120 so that a lower side of the ring 1120 is flushed with a lower side of the small lower portion so as to support and enhance the first protrusion 11.

Referring to FIG. 13, the window substrate 2 has a first pivotal hole 21 and a second pivotal hole 22 and a plurality of retaining holes 23. The first pivotal hole 21 is used to pivotally connect another end of the first driven unit 3 by using a pivotal joint 51. The second pivotal hole 22 serves to pivotally connect with another end of the second driven unit 4 by using a pivotal joint 53.

Referring to FIG. 6, the first driven unit 3 is a two staged plate. Two ends thereof have respective pivotal holes for passing through the pivotal join 51 and 52. A lateral side of the first driven unit 3 has a notch 30 for resisting the limiting block 112 as the first driven unit 3 is full open.

Referring to FIG. 12, the second driven unit 4 is a two staged plate. Two ends thereof have respective pivotal holes 41, 42 for receiving the pivotal joints 53 and 54. A lateral side of the second driven unit 4 has a notch 40 for resisting the limiting block 112 as the second driven unit 4 closes.

A bottom of the pivotal joint 51 has an enlarged portion 511. A bottom of each of the pivotal joints 52, 54 has an enlarged portion 520, 540. The heights of the enlarged portions 520, 540 are equal to a staged elevation 1 difference between the first protrusion 11 and the frame substrate 1 and the staged elevational difference between the second protrusion 12 and the frame substrate 1, respectively so as to support and enhance the first protrusion 11 and the second protrusion 12. A bottom of the pivotal joint 53 is a round tapered portion. The pivotal hole 41 of the second driven unit 4 has a shape corresponding to the round tapered portion of the pivotal joint 53 for stably and fully receiving the round tapered portion of the pivotal joint 53 not to interfere the operation thereof. The pivotal joints 51, 52, 53 and 54 are installed with washers 6.

Advantages of the present invention will be described herein. The structure is simple and firm. One limiting block is used for opening and closing operations so as to save the cost in parts and in assembly. The limiting block has the effects of supporting and enhancing the first protrusion. The enlarged block at the lower side of the pivotal joint at the connection of the first driven unit and the window substrate can support the weight of the window. Furthermore, bottoms of the pivotal joints 52, 54 can support and enhancing the first protrusion and second protrusion.

The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
