Abstract
The present invention relates to a refined assembly structure of hubbed door leaf installed with glass, which comprises a first door skin with an opening, a second door skin with an opening, a top lacing material, a bottom lacing material, a left lacing material, a right lacing material, a handle reinforcement member and the ejected frame with multiplayer glass hold-down. The door skin with opening can be manufactured to be various shapes such as square, rectangular, circle, ellipse, and semicircle depending on different mold. When assembled, the lacing materials are mounted to the edges of the first door skin by the adhesive. The left and the right lacing materials are position-bonded, by ribs, to the flush-sided door skin. The top and the bottom lacing materials are positioned through the milled notches at the top and the bottom ends of the left and the right lacing materials. A reinforcement member is disposed at the handle position to enhance the mechanical strength of the handle while locked. The openings of the two door skins have halving structure to halve-joint together when assembled to form a closed cabin therebetween. The bottom lacing material is then drilled with a hole through which the ammonium polyester foaming plastic is filled into the cabin so as to finish the assembling of the said door.

Detailed Description of the Embodiments of the Present Invention
[0048] The present invention discloses an assembly structure of a hubbed door leaf installed with glass, which comprises two door leaf skins 1 and 2 with an opening, a top and a bottom lacing materials 3, a left and a right lacing material 4, a handle reinforcement member 5, and a glass ejected-frame 6.
[0049] The said door skin 1 and 2 has a thickness of from about 1 mm to 4 mm; the four edges thereof are designed to be flush surface to be closely adhered to the top, the bottom, the left, and the right lacing materials 3 and 4 and then assembled. The said lacing material can be polyvinyl chloride foam profile, or wood, or steel, or ejected plastic, etc. The four edges of the opening of the door skin 1 are designed to be U shape structure 7, which are formed in one body. The four edges of the opening of the other door skin 2 are L shape structure 8, which are formed in one body. The rib 9 of the structure 8 inlays with the groove 10 of the U shape structure 7 when assembled for positioning purposes. A space of about 0.5 by 2.3 mm is left between the rib 9 and the groove 10 after being assembled in order to prevent the overflow of the adhesive when assembled.
[0050] A horizontal rib 11 is provided at the external edge of the U shape structure 7, which is utilized to support the multi-layer glass laid on the opening of the door. A groove 12 is provided at the surface of the rib, which can be spread with adhesive such as silicone before assembling the glass in order to closely bond the door and the glass to increase the watertight and gastight seals. The top of the U shape structure 11 is provided with two saw-shaped slopes 13 which form a horizontal groove with the external edge of L shape structure 8. The horizontal groove is provided to be inserted by the glass hold-down or the glass ejected-frame to fix the single layer or multi-layer glass.
[0051] The material of the said single layer or multi-layer glass ejected-frame can be wood, steel, polyvinyl chloride extrude profile, PVC foam profile, PVC plus wood scraps, polystyrene, polypropylene, or polypropylene plus fiber glass.
[0052] The material of the door skin 1 and 2 of the present invention can be the Sheet Molding Compound of reinforced fiber glass (referring to R.O.C. Invention patent No. 69423), wood fiber, steel or wood; the surface thereof can be a smooth surface without wood vein or be a mimetic wood vein. The depth of wood vein is about 0.05 to 0.2 mm. The opposite side of the said skin is a rough surface to increase the friction when the door is assembled by the adhesive.
[0053] The procedure of the assembly structure of hubbed door installed with glass is as follows (shown in FIG. 2):
[0054] First assemble the door skin 1 and 2, the top and the bottom lacing material 3, and the left and the right lacing material 4 with adhesive. Then, dispose a reinforcement member 5 at the handle position to enhance the mechanical strength of the handle while locked. The openings of the two skins halve and assemble each other (shown in FIG. 3). The adhesive can be used before halving in a practical example in order to increase its firmness. The left and the right lacing materials are position-bonded, by ribs, to the flush-sided door skin. The top and the bottom lacing materials are positioned through the milled notches 4-3 (refer to FIG. 1 and FIG. 2) at the top and the bottom ends of the left and the right lacing materials to form a closed cabin therebetween. The bottom lacing material is then drilled with a hole through which the ammonium polyester foaming plastic 21 is filled into the cabin to assemble the door (refer to FIG. 4 and FIG. 5). Then, the glass is laid in and fixed by the hold-down or the glass ejected-frame 6.
[0055] To refine the procedure, such as the necessity of processing by CNC center and of assembling the lacing material at the edges of opening, of the traditional hubbed door installed with glass, the present invention directly forms the edges of opening in one body during the manufacturing of the door skin and designs the edges of opening to be a halving structure to match the glass ejected-frame, to provide the following advantages:
[0056] 1. Saving the cost of lacing material.
[0057] 2. Decreasing the assembly labor by the halving assembly structure matching the glass ejected-frame.
[0058] 3. Forming in one body to avoid the procedure of cutting the opening to decrease the production of waste and to obtain good watertight and airtight seals.
[0059] 4. A reinforcement rib is designed at both the U shape structure and the glass ejected-frame structure to be strong enough to carry heavier load.
[0060] 5. The dimension of glass opening is 22 inches by 36 inches, which is most commonly used.
[0061] 6. The maximum width of the door is 35.75 inches which can vary depending on various needs.
[0062] 7. The bottom lacing material used in the swing door and window has two grooves so as to install the soft airtight lacing material much easier.
[0063] 8. The bottom lacing material used in the swing door and window can be drilled to install the roller.
