Abstract

A ventilated window structure for a panel door comprises a pair of top and bottom rails 1 and a pair of stiles 2. The stiles 2 have U shaped grooves 21 into which angle brackets 3 and holding blocks 5 are fitted. The blocks 5 have channels 31 for holding the ends of a louver 4 and a top surface with a triangular projecting member 52 and a bottom surface with a triangular opening 53. The angle brackets 3 have a triangular channel for holding the ends of a louver 4 and either a triangular projecting member 33 or a triangular slot 32 on a surface which fits into the U shaped channel. <IMAGE>

Description

AN IMPROVED STRUCTURE FOR A VENTILATED WINDOW IN A PANEL DOOR The present invention relates to a ventilated window structure in a panel door. More specifically, the present invention relates to the structure and installation method of a ventilated window in a panel door.

The ventilated window structure in a panel door has been improved and modified nowadays. The simplified structure of the window casing having several slant louvers has been replaced by a structure in which a plurality of "V" shaped louvers are enclosed. by sash bars. This conventional structure is simple in design which leads to complications during installation. Occasionally, the installation cannot be completed. Therefore, several versions of ventilated window structure with "V" shaped louvers are available but these conventional "V" shaped louvers in the ventilated window are easy to deform or beak. The installation process of the "V" shaped louvers is complicated as well as time and labor consuming. It is therefore very impractical to install these conventional "V" shaped louvers in the ventilated window.

Accordingly, one of the objects of the present invention is to provide a ventilated window in which the structure of the louvers are strengthened. A hollow triangular louver is used to replace the customary "V" shaped louver. The new structure is also modified so that the louvers can be mounted sturdily.

Another object according to the present invention is to provide a ventilated window structure the louvers of which are easier to install. The installation process is more efficient and simplified as coapared to the installation of a conventional ventilated window structure in a panel door.

An embodiment of the present invention will be described by way of example and with reference to the accompanying drawings, in which: FIG. 1 is a perspective fragmented view of the ventilated window according to the present invention; FIG. 2 is a partial diagrammatic fragmented view of the ventilated window according to the present invention; FIG. 3 is a horizontal cross-sectional view of an embodiment of the ventilated window assembly according to the present invention; FIG. 4 is a vertical cross-sectional view of an embodiment of the ventilated window assembly according to the present invention; and FIG. 5 is a perspective view of the ventilated window mounted in a panel door according to the present invention.

Referring to FIG. 1 and FIG. 2, the structure of the ventilated window in a panel door according to the present invention includes a pair of top and bottom rails 1, a pair of left and right stiles 2, a plurality of angle brackets 3, a plurality of hollow triangular louvers 4, a plurality of holding blocks 5 and a hold-down molding 6. The top and bottom rails 1 may be of conventional structures and therefore are not being described.

The angle bracket 3 which is a right-angle bracket made to fit into a groove 21 of the stile 2. The vertical surface on each of the angle bracket 3 has a triangular channel 31 which is used for the insertion of the hollow triangular louver 4. The bottom surface of the top angle bracket 3 has a triangular slot 32 which is used for another louver 4 to fit in. The -top surface of the bottom angle bracket 3 has a triangular projected block 33.

Each of the hollow triangular louver 4 is made up of layers of slat and is being into the triangular shape.

The top and the bottom slats are secured together by a rib plate 41.

The holding block 5 has a shaped to fit into the U-shaped groove 21 of the stile 2. The corresponding vertical surfaces on both sides of the holding blocks 5 have triangular channels 51. The top surface on each of the holding block 5 has a triangular projected member 52 which is used for the bottom surface of the hollow triangular louver 4 to snap on. Each of the holding blocks 5 has a triangular opening 53 on its bottom surface.

In use, the bottom rail 1, which can be appropriately fabricated, and the stiles 2 on both sides can be attached to the window frame opening by using a pair of the angle brackets 3, which are installed on the bottom of the window frame. A U-shaped window frame is now assembled without the top rail 1. At this time both ends of the hollow triangular louver 4 are being inserted into the angle bracket 3. Then both ends of the triangular louver 4 are being placed in the triangular projected blocks 33 of the bottom angle brackets 3. Another hollow triangular louver 4 is then being inserted into the triangular channels 51 of the holding blocks 5. These holding blocks 5 with the hollow triangular louver 4 are then slided into the U-shaped grooves 21 on the stiles 2. Using the triangular opening 53 on the bottom of the holding block 5, the triangular louver 4 inserted earlier into the top surface of the angle bracket 3 can be securely mounted in place. The U-shaped window frame can be stacked up with the hollow triangular louvers 4 by repeating the above operation.

Then the top rail 1 with the angle bracket 3 at both ends of the hollow triangular louver 4 at the very top are assembled together with the U-shaped window frame to form a rectangular window frame assembly. The completed window frame assembly is then installed into the opening of the panel door 0. The right-angle edge boards 11 and 22 of the rails and the stiles will be fitted into the edges of the window frame. The holddown molding 6 will be attached from the other end of the window frame cut-out such that a strip 61 is inserted into gaps 12 and 23 of the rails 1 and the stiles 2, as is shown in FIG. 3 and FIG. 4. This provides a secure and firm installation of the ventilated window in the panel door 0, as is shown in FIG. 5. This design simplifies the complicated assembly process so that the installation efficiency is greatly enhanced. The installation cost is also reduced.

Moreover, the window frame structure with the hollow triangular louver 4 is firm and is impact resistant. It is therefore a practical structure to be used in a panel door.
