PRIOR ART

It is known in these category that there is a Taiwan Utility Model application no. 84204994, titled as “An improvement for the assembly structure of pressed-molded door”, applied and granted prior to this invention. However, the said patent has defects regarding the gluing process, material used, assembly time, and size flexibility. This invention is to solve the above problems and upgrade the efficiency for assembly.

SUMMARY OF THE INVENTION

This invention relates to the press molded door with an improvement for reinforced material and stile structure comprising two door panels, two top and bottom stiles, two left and right stiles and an interior reinforced material, is characterized by that the flexible-rigid co-extrusion convex structure of the interior reinforced material. The above mentioned interior reinforced material is made with the door panel together by a single mold that can reduce the assembly time, enhance the strength of door and the stability of quality. The above mentioned reinforced material used in the handle is set inside the interior reinforced material to form a closed space with two top and bottom stiles. Finally an imitation wood grain door is finished.

Besides, the above mentioned left and right reinforced material of this press molded door has a groove to be connected with the convex part of the left and right stiles, and then combine with top and bottom stiles and two door panels to form a closed space. After that, it is drilled a hole on the bottom stile for filling of polyurethane inside to make an imitation wood grain door.

Moreover, the press-molded door of this invention can be made different width according to customers' needs, by cutting two sides of the door.

Furthermore, by putting the left and right stiles with different width, we can get a door with different width.

Numeral 15 is polyurethane.

The construction of this invention comprises:

(1). two door panels ( 71,81,91) having ribs on both sides;

(2). a plastic-extruded interior reinforced material ( 7);

(3). two plastic-extruded left and right stiles ( 5, 5′) which can be 6 mm or 10 mm width as required;

(4). two top and bottom stiles ( 8, 9) and

(5). handle's reinforced material ( 10).

The door is centered with the plastic-extruded interior material ( 7), supporting with door panels (71,81,91) having ribs on both sides, and are glued and fixed together with each other. Due to the reinforced material is rigid PVC, there are convex hollow structures appropriated spaced in support of door panels. This single molded structure can reinforce the door strength, facilitate the assembling processes, reduce the defect products, and improve the defects of that the reinforced materials are scattered away and are assembled individually and thus causing waste of time and cost, and lack of strength.

The left and right stiles are made of PVC with co-extrusion technique, on which the co-extruded convex parts ( 12, 12′) are inserted with the concave parts of interior reinforced material and formulate a firm construction without gluing. Further, the rigid PVC is easy for modification, and is therefore can match special requirements of door or frame by modifying the appearance dimensions to prevent the defects of glue's overflow in conventional structure and the difficulty for partial modifying work.

Another model of this invention is that the left and right reinforced materials ( 14) having groove shapes are joined together with the convex parts of the left and right stiles (5, 5′), and then are matched with the top and bottom stiles and two door panels to form a closed space. After that, it is drilled a hole at the bottom stile for filling polyurethane to the inner part, and form an imitation wood texture door.

This invention can be made different dimensions of door width as required. The manufacturing method is that using a plastic-extruded interior reinforced material ( 7), the top and bottom stiles and two door panels to form a closed space. And by cutting the required width after gluing them together, cutting groove on both sides to make left and right stiles with groove shape. Then putting it to be inserted with the flexible-rigid coextruded PVC, to form an imitation wood grain door.

For the preceding method, its plastic-extruded interior reinforced material can be replaced by filling polyurethane to increase the flexibility and multi-patterns.

Generally, the raw material of door can be either thermosets or thermoplastics. During the manufacturing process of thermosets, the FRP (fiber reinforced plastic) additive is not compulsory, and the door made of can be recycled for other purpose to fulfill the requirement of environment protection. Besides, if adding Al (OH) ₃in the compounding, it can be fireproof providing living safety. If this invented door can replace wood-made door, it can reduce wood chopping in large amount, and protect the precious resource of forests.

In summary, this creation can save many manufacturing steps, simplify the assembling procedures, and cut down the manpower cost. Besides, this door structure is firm and easy for cutting, and it can anti-moisture and prevent door bending. Therefore, this invented door is useful, economic and creative, and can promote product quality, and as a result, is novel and nonobviousness.
