Benefits of technology

[0004]This invention is intended to overcome the technical roadblocks and provide a lightweight edge-sealed table top panel with paper honeycomb cores, which is environmentally friendly, beautiful, highly strong, cost-effective, and easy to clean.
[0007]The said internal fixed part is pipe fitting or extrusion section bar or injection-molded fittings or composite work piece constituted by hardware and it can be used to enhance the connection strength of reinforced table leg mechanism and table top panel.
[0016]The said bottom panel can also be of one-piece with several reinforcing ribs to reinforce the strength of table top panel.
[0022]The beneficial effect of this invention is as follows. Firstly, as the lightweight paper honeycomb core is used as the filling between top panel and bottom panel, i.e. the core of table top panel, the finished table top panel is light in weight. Secondly, the internal fixed part such as core set in the paper honeycomb cores is completely or partially covered with composite work piece made of pipe fittings or extrusion section bars, or composite work piece constituted by pipe fitting or extrusion section and injection-molded fittings or hardware, enabling connection between the table top panel and other parts like table leg mechanism. Furthermore, it may be used as the reinforced frame of table top panel to greatly enhance the strength of table top panel. This invention particularly adopts the above mentioned edge-sealed structure in top panel and bottom panel, which makes the paper honeycomb core plate good-looking and is useful in improving the production efficiency.
[0023]Since the top panel and bottom panel are formed by monolayer plastic plate or multilayer plastic composite plate made by suction moulding process or contour machining process, the table top panel can be designed in various shapes upon requirement without further processing and is easy to clean and strong in moisture resistance; the edge of table top panel is formed by bending panel, ensuring a more smooth and beautiful table top panel which is quite flat and seamless without bonding gap. An edge-sealed table top panel with environmentally friendly paper honeycomb cores which is made of invert suction moulding process is characterized by light weight, high strength, easy maintenance, cost-effectiveness and beautiful appearance.

Problems solved by technology

The raw material of aforementioned table top panels is mostly wood, which will be greatly limited by restrictions to tree cutting as forest resource is decreasing.
On the other hand, there are some drawbacks for the table top panel made of woody materials.
For example, it is too heavy to move a fiber board of medium density and too vulnerable to maintain a particle board as it is week in strength.
What's more, it is hard to clean such top panel due to its poor moisture resistance.
Meanwhile, the cost of table top panel made of woody materials is higher as a result of expensive raw material.
Although the table top panel made of one-piece blow moulding plastic plate is light in weight, it is expensive in manufacturing and difficult in changing shape.
The existing paper honeycomb core panels are mainly used in the package of fragile articles or stack board for transportation, and the furniture made of them is poor in appearance; besides, the present honeycomb cardboard can not be nailed, drilled or connected with other parts to become furniture or products.

embodiment 1

[0045]As shown from FIG. 1 to FIG. 4, an edge-sealed table top panel with paper honeycomb cores made of invert suction moulding process , is composed of plastic top panel 11, plastic bottom panel 12, paper honeycomb core 13 and internal fixed part 14, wherein the plastic top panel 11 and plastic bottom panel 12 are square, making the table top panel made of said panels is also a square one; the plastic top panel 11 and the plastic bottom panel 12 are formed by suction moulding process or contour machining process; the thickness of plastic top panel 11 and plastic bottom panel 12 is about 0.3 mm-4 mm; when the plastic top panel 11 and plastic bottom panel 12 are processed to be a square with desired size, fill the paper honeycomb core 13, composed of paper honeycomb element 133, top sheet 131 and bottom sheet 132, between plastic top panel 11 and plastic bottom panel 12; it is known that the paper honeycomb core can only be provided with the paper honeycomb core, without top sheet an...

embodiment 3

[0049, as shown in FIG. 6: The table top panel is composed of top panel 11, bottom panel 12, paper honeycomb cores 13 and internal fixed part 14; the top panel 11 and bottom panel 12 form a close space filled with paper honeycomb core which is bonded to top panel 11 and bottom panel 12 or either of them; the internal fixed part 14 is set inside all edges or partial edges of table top panel and remains the same height as paper honeycomb core; the edge of starting end of edge of bottom panel 12 bending upwardly protrudes the top panel at a thickness of 12.1, and then extends internally and upwardly a length of 12.2; the downwardly bending side 11.1 of top panel 11 bonds to the upper extension section 12.2 of bottom panel and forms a plane with 12.1. Of course, this structure can be in invert order, i.e. the top panel protrudes the bottom panel at an approximate thickness of bottom panel.

embodiment 4

[0050, as shown in FIG. 7: The table top panel is composed of top panel 11, bottom panel 12, paper honeycomb core 13 and internal fixed part 14; the downwardly bending edge of top panel 11 and the upwardly bending edge of bottom panel 12 form a close space filled with paper honeycomb core which is bonded to top panel 11 and bottom panel 12 or either of them, internal fixed part 14 is set inside all edges or partial edges of table top panel and keeps the same height as paper honeycomb core.

[0051]Embodiment 5: as shown in FIG. 8: The table top panel is composed of top panel 11, bottom panel 12, honeycomb paper core 13 and internal fixed part 14; the edge of top panel 11 bends downwardly; the upwardly bending edge of bottom panel 12 forms a cavity and then bends upwardly, forming a close space filled with paper honeycomb core which is bonded to top panel 11 and bottom panel 12; the internal fixed part 14 is set at the edge between the top panel 11 and bottom panel 12 with its height la...

Abstract

The present invention relates to a panel with paper honeycomb cores, which is usable as a table top. The panel comprises a top panel, a bottom panel, paper honeycomb cores and an internal fixed part, in which the paper honeycomb cores are filled in the closed space which is enclosed by the top panel and the bottom panel, and are fixed with the top panel and the bottom panel. The peripheries of the paper honeycomb cores are completely or partially surrounded by the internal fixed part, or the internal fixed part is installed in the suited position of the panel, and the internal fixed part serves as the stiffening art of the panel. The edge of the bottom panel and the lower edge of the top panel, which is formed by ending the top panel downwards are cohered together, and the flection of the top panel forms the side edge of the panel. The top panel and the bottom panel may be formed by suction moulding process or contour machining process directly. The panel having the structure described above can connect with other parts of the table.
