Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a window or door closure device, and more particularly to a window or door closure device having an air ventilating structure for air to selectively circulate through the closure devices.
2. Description of the Prior Art
Typical closure devices, such as windows, doors, transoms, sliding blinds, or the like, comprise one or more, such as two panels slidably received in a sash or window frame or door frame, and movable relative to each other, for allowing the closure devices to be selectively opened or closed.
For example, U.S. Pat. No. 324,384 to Jewett discloses one of the typical sliding blinds which also comprise two or more panels slidably received in a window or door frame or sash, and movable relative to each other, for selectively opening and closing the closure devices. However, the sliding panels should include air circulating holes or orifices formed therein, through which rain or inset or dust may enter into the house buildings.
It is to be noted that the air circulating holes or orifices of the sliding panels are normally inclined inwardly and downwardly relative to the house buildings, such that the rain may easily flow through the air circulating holes or orifices of the sliding panels and then enter into the house buildings.
U.S. Pat. No. 4,554,770 to Anders discloses a typical horizontal sliding window with removable fixed sash, and also comprising two or more panels slidably received in a window or door frame or sash, and movable relative to each other, for selectively opening and closing the closure devices. However, when the sliding panels are moved relative to each other to the opening position, the typical sliding window should be widely opened, such that the rain or inset or dust may also easily enter into the house buildings.
In addition, in some of the huge constructions or house buildings, the outer peripheral portions thereof may be attached and enclosed with fixed glass windows that may not be opened, such that air may not enter into the house buildings naturally, and such that air conditioning facilities should be energized or operated all day long, and may consume much electric energy.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional closure devices.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a window or door closure device including an air ventilating structure for air to selectively circulate through the closure devices.
In accordance with one aspect of the invention, there is provided a closure device comprising a frame including a sill member and a head member, a fixed outer sash including a sheet member fixedly secured between the sill and the head members, and including a plurality of orifices formed therein, and a slidable inner sash including a sheet member slidably disposed between the sill and the head members, and including a plurality of apertures formed therein, and arranged to be selectively offset from the orifices of the fixed sash, or arranged to be selectively aligned with the orifices of the fixed sash and to allow air to flow through the apertures of the sheet member of the slidable sash when the sheet member of the slidable sash is moved relative to the sheet member of the fixed sash.
The sill and the head members each includes a rail provided therein to slidably attach the sheet member of the slidable sash. The slidable sash includes at least one wheel attached to the sheet member thereof, for engaging with the rail, and for facilitating a sliding movement of the sheet member of the slidable sash along the rail of the frame.
The fixed sash includes a plurality of plugs attached to the orifices of the sheet member respectively, and each having a hole formed therein, for selectively offsetting from and for selectively aligning with the apertures of the sheet member of the slidable sash. The plugs each includes two peripheral flanges extended radially and outwardly therefrom, for engaging with the sheet member of the fixed sash, and for securing and anchoring the plugs to the sheet member of the fixed sash.
The holes of the plugs are inclined outwardly and downwardly relative to the sheet member of the slidable sash, to prevent water or rain from flowing through the inclined holes of the plugs. The orifices of the sheet member of the fixed sash include an inner diameter greater than that of the apertures of the sheet member of the slidable sash, for attaching the plugs.
A moving device may further be provided for moving the sheet member of the slidable sash relative to the sheet member of the fixed sash, for example, the moving device may include a pusher engaged with the sheet member of the slidable sash, to selectively move the sheet member of the slidable sash relative to the sheet member of the fixed sash.
For example, the moving device may include a motor or a hydraulic device coupled to the pusher, to operate the pusher. A detector may be coupled to the moving device, to selectively operate the moving device, when detecting that the content of the carbon oxide (CO) or the carbon dioxide (CO₂) in the house buildings is over a predetermined level, for example, to prevent the users from being suffocated inadvertently.
Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings, and initially to FIGS. 1 and 2, a closure device in accordance with the present invention is provided or arranged for mounting in an opening in a house building, and functioned as a door, a window, a sliding blind, a transom, or the like, and comprises a frame 1 including a horizontal sill member 10 and a horizontal head member 10 each having one or more rails 11, 12, 13 formed or provided therein, such as two rails 11, 12 (FIGS. 1-3), three rails 11-13 (FIG. 4), or the like.
A fixed outer sash 3 includes a glass or sheet member 30 stably or fixedly disposed or secured in one of the rails 12 of the members 10, and a slidable inner sash 2 also includes a glass or sheet member 20 slidably disposed or attached in the other rail 11, and disposed or arranged parallel to the fixed outer sash 3, and arranged to slide relative to the sheet member 30 of the fixed outer sash 3. As shown in FIG. 4, a screen 70 may further be provided and disposed or attached to the further rail 13.
The frame 1 may further includes one or more vertical splines 14 and/or one or more vertical jamb members 15 disposed or attached to the sides of the horizontal sill and the head members 10 and/or to the sides of the fixed outer sash 3, in which the vertical splines 14 may each include a serrated or flexible portion 16 formed or provided therein, for snugly or sealingly engaged with the vertical jamb members 15 and/or the sheet members 20, 30 of the sashes 2, 3, for example.
As shown in FIG. 4, a gasket or sealing strip 17 may further be provided and disposed or attached to the outer peripheral portion of the sheet member 30 of the fixed outer sash 3 and the horizontal sill and the head members 10 and the vertical splines 14 or the vertical jamb members 15, for making or forming a water tight seal therebetween, and for preventing water or rain from passing through the fixed outer sash 3 and from entering into the frame 1. The slidable inner sash 2 may further include one or more rollers or wheels 23 attached to the sheet member 20 (FIG. 1), for engaging with the rail 11 of the frame 10, and for facilitating the sliding movement of the sheet member 20 along the rail 11 of the frame 10.
The sheet member 30 of the fixed sash 3 includes a number of orifices 31 formed therein, and the sheet member 20 of the slidable sash 2 also includes a number of apertures 21 formed therein, and arranged to be selectively aligned with the orifices 31 of the sheet member 30 of the fixed sash 3 (FIGS. 1-3 and 5), or to be offset from the orifices 31 of the sheet member 30 of the fixed sash 3 (FIG. 6), when or by moving the sheet member 20 of the slidable sash 2 relative to the sheet member 30 of the fixed sash 3.
A number of blocks or plugs 40 may further be provided and disposed or attached or engaged into the orifices 31 of the sheet member 30 of the fixed sash 3 respectively, and each includes a hole 41 formed or provided therein, and also arranged for selectively offsetting from the apertures 21 of the sheet member 20 of the slidable sash 2 (FIG. 6), or for aligning with the apertures 21 of the sheet member 20 of the slidable sash 2 (FIGS. 2-3 and 5), to allow the air to selectively flow through the apertures 21 of the sheet member 20 of the slidable sash 2 and thus to flow into the house buildings.
Each of the plugs 40 includes two peripheral flanges 42 extended radially and outwardly from the two end portions thereof respectively, for engaging with the sheet member 30 of the fixed sash 3, and thus for securing or anchoring the plugs 40 to the sheet member 30 of the fixed sash 3. It is preferable that the holes 41 of the plugs 40 are inclined outwardly and downwardly relative to the sheet member 20 of the slidable sash 2 or the house buildings, best shown in FIG. 3, to prevent the water or the rain from flowing through the inclined holes 41 of the plugs 40, and thus to prevent the water or the rain from entering into the house buildings.
It is further preferable that the orifices 31 of the sheet member 30 of the fixed sash 3 include an inner diameter greater than that of the apertures 21 of the sheet member 20 of the slidable sash 2, and the holes 41 of the plugs 40 include an inner diameter identical or close to that of the apertures 21 of the sheet member 20 of the slidable sash 2, for suitably aligning with the apertures 21 of the sheet member 20 of the slidable sash 2.
In operation, the sheet member 20 of the slidable sash 2 may be moved relative to the sheet member 30 of the fixed sash 3 manually by the users, or automatically by a motorized pusher 51 (FIGS. 5, 6), in order to selectively align the apertures 21 of the sheet member 20 of the slidable sash 2 and/or the holes 41 of the plugs 40 with the orifices 31 of the sheet member 30 of the fixed sash 3 (FIGS. 1-3 and 5), to allow the air to selectively flow through the apertures 21 of the sheet member 20 of the slidable sash 2 and then to flow into the house buildings.
On the contrary, the apertures 21 of the sheet member 20 of the slidable sash 2 and/or the holes 41 of the plugs 40 may also be selectively offset from the orifices 31 of the sheet member 30 of the fixed sash 3 (FIG. 6), when or by moving the sheet member 20 of the slidable sash 2 relative to the sheet member 30 of the fixed sash 3 manually by the users, or automatically by the motorized pusher 51, to block the orifices 31 of the sheet member 30 of the fixed sash 3, and thus to prevent the air or the water from entering into the house buildings.
As shown in FIGS. 5, 6, the motorized pusher 51 may be engaged with the sheet member 20 of the slidable sash 2, and coupled to and operated or actuated by such as a motor 50, a hydraulic actuator 50, or other actuating or moving means or devices 50, in order to move the sheet member 20 of the slidable sash 2 relative to the sheet member 30 of the fixed sash 3. A sensor or detector 60 may further be provided for detecting the air quality or the air quantity or air content or the content of the carbon oxide (CO) or the carbon dioxide (CO₂) in the house buildings, for example.
In addition, the sensor or detector 60 may be attached or coupled to the moving devices 50, in order to actuate the moving devices 50 to move the sheet member 20 of the slidable sash 2 relative to the sheet member 30 of the fixed sash 3, and to align the apertures 21 of the sheet member 20 of the slidable sash 2 and/or the holes 41 of the plugs 40 with the orifices 31 of the sheet member 30 of the fixed sash 3, and to allow the air to flow into the house buildings, when the sensor or detector 60 has detected that the content of the carbon oxide (CO) or the carbon dioxide (CO₂) in the house buildings is over a predetermined level, for example, and thus to prevent the users from being suffocated inadvertently.
It is to be noted that the blocks or plugs 40 are shown to be provided and disposed or attached or engaged into the orifices 31 of the sheet member 30 of the fixed sash 3 respectively, however, the blocks or plugs 40 may also be selectively attached to the sheet member 20 of the slidable sash 2 instead of the fixed sash 3. The orifices 31 are not required to be formed and inclined relative to the sheet member 30 of the fixed sash 3, to allow the orifices 31 to be formed and manufactured relatively easier, because it will be difficult to form inclined orifices 31 in the glass or sheet members 30.
Accordingly, the window or door closure device in accordance with the present invention includes an air ventilating structure for air to selectively circulate through the closure devices.
Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
