Abstract

A window assembly includes two pieces of glass engaged in the window frame and a base is connected to the window frame. A reservoir and a pump are received in the base and a liquid with desired color is received in the reservoir. The liquid is pumped in the gap between the two pieces of glass so as to perform as a curtain.

Description

FIELD OF THE INVENTION

The present invention relates to a window assembly comprising two pieces of glass and a fluid being filled between the glasses to perform as a curtain.

BACKGROUND OF THE INVENTION

A conventional window comprises one or two pieces of glass and in order to block the strong brightness outside of the window entering the interior of the room, a curtain is used to reduce the affection of the brightness outside of the room to the people in the room. The conventional curtains although include many types such as blinds and fabric curtain, however, both of the two types of curtains are difficult to be detached from the window frame and to be clean. Besides, to replace or change a new curtain is costly and takes a lot of time. Usually, the users cannot easily to install a new curtain by themselves.

SUMMARY OF THE INVENTION

In accordance with one aspect of the present invention, there is provided a window assembly which comprises a base in which a reservoir for receiving liquid and a pump are received. A first pipe is connected between the reservoir and the pump. A frame has a groove defined in each of four inner sides thereof and two pieces of glass are engaged with the groove of the frame. A gap is defined between the two pieces of glass. An opening is defined in a lower side of the frame and communicates with the gap. A second pipe has an end connected to the pump and the other end of the second pipe is engaged with the opening.
The primary object of the present invention is to provide a window assembly wherein a liquid with desired color can be filled a gap between two pieces of glass so as to be used as a curtain.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to Figs. 1 and 2, the window assembly of the present invention comprises a base 20 and a frame 10 connected on a top of the base 20. A reservoir 23 for receiving liquid and a pump 22 are received in the base 20. The liquid may have a desired color. A first pipe 24 is connected between the reservoir 23 and the pump 22.
The frame 10 has four inner sides and a groove 11 is defined in each of the inner sides and two pieces of glass 12 are engaged with the grooves 11 of the frame 10. A gap 121 is defined between the two pieces of glass 12 and sealed between the frame 10. An opening 112 is defined in a lower side of the frame 10 and communicates with the gap 121. A second pipe 240 has an end connected to the pump 22 and the other end of the second pipe 240 is engaged with the opening 112.
Referring to Figs. 3 and 4, when the pump 20 is activated by a proper switch or control device, the liquid in the reservoir 23 is pumped into the gap 121 via the opening 112 so that the interior is blocked from being seen from outside by the liquid.
Figure 5 shows a second embodiment of the present invention and is similar to that of the window assembly as shown in Figs. 1-4 except that an inlet 113 and an outlet 114 are respectively defined in the lower side of the frame 10 and communicate with the gap 121 between the two pieces of glass 12.
A first pipe 25 is connected between the reservoir 23 and the pump 22, and a second pipe 251 has an end connected to the pump 22 and the other end of the second pipe 251 is engaged with the inlet 113. A third pipe 252 has an end connected to the reservoir 23 and the other end of the third pipe 252 is engaged with the outlet 114. By the arrangement. The liquid can be filled into the gap 121 or removed from the gap 121 within a short period of time via the inlet 113 and the outlet 114.
Figure 6 shows a third embodiment of the window assembly of the present invention, wherein a base 20 is connected to a top of the frame 10 and a motor 26 and a mandrel 27 are received in the base 20. A curtain piece 28 is wrapped around the mandrel 27. A pulley is connected to an end of the mandrel 27 and a belt 261 reeves through the pulley and an output shaft of the motor 26. A slot 115 defined in a lower side of the frame 10 and communicating with the gap 121. A leading edge of the curtain piece 28 is inserted in the slot 115. When the motor 26 is activated, the mandrel 27 is rotated by the belt 261 and the curtain piece 28 is lowered into the gap 121 so as to perform as a curtain.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
