Closure device having ventilating structure

Abstract

A closure device includes an outer sash fixedly secured between the sill and the head members of a frame and having a number of orifices formed in a sheet member, and a slidable inner sash slidably disposed between the sill and the head members and having a number of apertures arranged to be selectively offset from the orifices of the fixed sash, or selectively aligned with the orifices of the fixed sash and to allow air to selectively flow through the apertures of the sheet member of the slidable sash. A number of plugs may be attached to the orifices of the fixed sash and each has a hole for selectively offsetting from and aligning with the apertures of the sheet member of the slidable sash.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] 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. [0003] 2. Description of the Prior Art [0004] 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. [0005] 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 ther...

AI Technical Summary

Benefits of technology

[0012] 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.

[0014] 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.

Problems solved by technology

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.
