1. Field of the Invention
The present invention relates to a window assembly and, more particularly, to an adjustable light-receiving window assembly.
2. Description of the Related Art
Spaces for windows are usually preserved when designing buildings. With reference to
A window covering device such as a blind, shade, curtain, drapery, or the like is provided to the window for keeping noise and dust outside and for blocking light. There are various types of window covering devices operated by different methods. The window covering device 2 shown in
An objective of the present invention is to provide an adjustable light-receiving window assembly including a window having a compartment that can be covered to control the light-receiving effect.
In accordance with a first aspect of the present invention, an adjustable light-receiving window assembly comprises a window and a window covering device. The window includes a window frame and at least two light-transmittable panes mounted on the window frame to define a compartment with an opening in communication with outside. The window covering device is mounted adjacent to the compartment and includes a light-shielding member extending into the compartment via the opening. The window covering device further includes an operative member mounted above the opening. The operative member is operable to move the light-shielding member between an extended state and a folded state for selectively blocking light transmitted through the at least two light-transmittable panes.
In accordance with a second aspect of the present invention, an adjustable light-receiving window assembly comprises a window and a window covering device. The window includes a window frame and at least two light-transmittable panes mounted on the window frame to define a compartment with an opening in communication with outside. The window covering device is mounted adjacent to the compartment and includes a light-shielding member extending into the compartment via the opening. The window covering device further includes a controllable motor for moving the light-shielding member between an extended state and a folded state for selectively shielding light transmitted through the at least two light-transmittable panes.
Other objectives, advantages, and features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
Referring to
The window frame 31 is not limited to the above-mentioned integrally formed U-shaped structure. In another example shown in
The housing 32 is mounted on top of the window frame 31 and seals the opening 341. The window covering device 4 has an end fixed to the housing 32 and aligned with the opening 341. The window covering device 4 includes a light-shielding member 41 (a shade in this example), a shaft 43, and an operative member 42. With reference to
The operative member 42 can be operated to turn the shaft 43. In this example, the operative member 42 is a hand wheel with a spindle for driving the shaft 43 to turn. The hand wheel may withstand considerable torque. When a user turns the operative member 42, the light-shielding member 41 is movable in the compartment 34 in a vertical direction between a folded position and an extended position for winding or unwinding purposes. Hence, a light-blocking effect is provided when the light-shielding member 41 is in the fully extended state and received in the compartment 34. The user may turn the operative member 43 in a direction to drive the shaft 43 for moving the light-shielding member 41 upward and winding the light-shielding member 41 around the shaft 43. Light is not blocked by the light-shielding member 41 when the light-shielding member 41 is in its wound state.
When the light-shielding member 41 is in the folded position not shielding the window 3, the user may operate the operative member 43 in a reverse direction such that the light-shielding member 41 moves downward under gravity into the compartment 34 until the window 3 is shielded by the light-shielding member 41.
The hand wheel (i.e., the operative member 42) may withstand considerable torque. Namely, the hand wheel can be turned to any desired position and then retained in the position for retaining the light-shielding member 41, thereby controlling the light-receiving effect of the window 3. The panes 33 are not limited to glass material. Namely, the panes 33 may be made from other material such as acrylic or reinforced plastic material that allows transmission of light.
As apparent from the foregoing, the light-shielding member 41 is sealed in the compartment 34 without in contact with outside. Hence, the light-shielding member 41 is less likely to get dirty. Furthermore, no cord is required for moving the light-shielding member 41. The risks of malfunction of the shade resulting from breaking of the cord and injury to the children playing nearby are avoided.
With reference to
More specifically, the window covering device 4 includes a controllable motor 44 for driving the operative member 42. The motor 44 is mounted above the opening 341 and coupled with an end of the shaft 43 for driving the shaft 43 to thereby wind or unwind the light-shielding member 41. The motor 44 is housed in the housing 32. A controller 440 is located outside the housing 32 and connected to the motor 44 via a wire (not labeled). The user may operate the controller 440 to control the rotating direction of the motor 44 for driving the shaft 43 to thereby move the light-shielding member 41 between the folded state and the extended state. It is noted that the controller 440 may be replaced with a wireless controller, which is well know in the art.
With reference to
The motor 44 includes a roller 441 mounted on and slidable along the track 45. Furthermore, the motor 44 is coupled with an outermost slide 46 adjacent to the motor 44. When the motor 44 is turned on and moves along the track 45, the outermost slide 46 is moved to slide along the track 45. Hence, the other slides 46 are moved along the track 45, moving the light-shielding member 41 to an extended state for blocking light or a collapsed state not blocking the light.
In conclusion, the window assembly in accordance with the present invention includes a window 3 with a compartment 34 defined by a window frame 31 and a plurality of light-transmittable panes 33 as well as a light-shielding member 41 sealed in the compartment 34. The light-shielding member 41 is protected and, thus, less likely to get dirty while allowing adjustment in the light receiving effect. The problems resulting from the use of a cord in the conventional designs are avoided.
Although specific embodiments have been illustrated and described, numerous modifications and variations are still possible. The scope of the invention is limited by the accompanying claims.
