Detailed Description

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings. What has been described herein is merely a preferred embodiment in accordance with the present invention and other ways of practicing the utility model will occur to those skilled in the art and are within the scope of the utility model.

The utility model provides a panel and furniture with the panel. Fig. 1-7 show a first embodiment according to the present invention; FIGS. 8-13C illustrate a second embodiment according to the present invention; fig. 14-19 show a third embodiment according to the present invention. It should be noted that, in the first place, the term "plastic blank plate" and "plastic sheet material" as used herein refer to the same component as it is in different process stages, and in the process it is called "plastic blank plate" and in the final formed sheet material it is called "plastic sheet material". Also, the directional terms referred to herein are used in an illustrative sense only and are not intended to be limiting, and they can be understood with reference to the directions shown in the drawings.

A first embodiment according to the present invention will be described below with reference first to fig. 1 to 7. Fig. 1, 2, 3A, 4, 5A, and 6A show several steps performed in sequence in the method of manufacturing a plate material in the first embodiment.

First, referring to fig. 1, the sheet material 1 to be manufactured by the present embodiment (the finished sheet material 1 is shown in fig. 7) includes a frame 12, the frame 12 is formed in a substantially rectangular shape, and the frame 12 has three transverse beams 122 extending in a transverse direction D2 and two longitudinal beams 121 extending in a longitudinal direction D1. The general shape of the finally produced panel 1 will be similar to the shape of the frame 12, i.e. the produced panel 1 is also formed substantially as a plate-like structure defined by a transverse direction D2 and a longitudinal direction D1, then the direction perpendicular to the extension direction of the panel 1 can be understood substantially as the third direction D3 shown in fig. 1, the third direction D3 being perpendicular to both the transverse direction D2 and the longitudinal direction D1.

In the step shown in fig. 1, the frame 12 is first placed on top of a mould 2 having a shape matching the shape of the frame 12. Preferably, a step 22 surrounding the body 21 of the mold 2 is provided at the bottom edge of the mold 2, and the frame 12 is configured to be fittingly rested on the step 22 around the body 21 of the mold 2. Also, the body 21 of the mould 2 is provided with a slit 23 at a position intermediate to the longitudinal direction D1 for fittingly receiving the transverse beam 122 at the centre of the rim 12. This arrangement enables the rim 12 to be snugly fitted over the mould 2 and thereby form a separable unit with the mould 2.

The plate manufactured by the process comprises a plastic plate forming a plate main body and a frame attached to the lower surface of the main body of the plastic plate, wherein the frame is formed with a protruding part protruding outwards along the extending direction of the plate main body, and at least the outwards surface of the protruding part is covered by the plastic plate. Wherein, the plastic plate is directly coated outside the frame through plastic uptake molding, so that the protruding part of the frame is embedded in the plastic plate, and the plastic plate is prevented from being separated from the frame. It should be noted that the term "outwardly facing surface" as referred to herein refers to the outwardly facing surface of the projection, which may be understood to include both side and bottom surfaces. The term "edge of the plastic sheet" is understood to mean a cut trace of the plastic blank sheet.

Also preferably, the top surface of the mold 2 is formed with a plurality of protruding ribs 54 arranged at intervals in the longitudinal direction D1 and extending in the lateral direction D2, respectively, the function of which will be described in detail later.

Referring to fig. 2, after the frame 12 is mounted on top of the mold 2, the next step is to place a plastic blank sheet 11 on the top surface of the mold 2 on which the frame 12 is mounted. The plastic blank plate 11 may be, for example, a polypropylene plate.

As shown in fig. 3A, next, suction is applied (for example, by vacuum forming) in a direction perpendicular to the extending direction of the plate material 1, that is, in a third direction D3 to form the plastic blank plate 11 by using a vacuum forming process, so that the plastic blank plate 11 is wrapped on the frame 12 and the mold 2, so that the combined top surface and side surface of the frame 12 and the mold 2 can be closely attached to the plastic blank plate 11 as shown in fig. 3A to 3C. Since the top surface of the mold 2 is an uneven surface, the plastic blank plate 11 formed by suction molding on the mold 2 is also formed into an uneven shape. Such setting is because the plastic uptake step is hot-forming, and the shrinkage can take place after the cooling of the plastic blank board 11 after the drawing of patterns, and if the plastic blank board 11 has such concave-convex line this moment, then these concave-convex parts can compensate the shrinkage of plastic blank board 11 for the plastic blank board 11 after the cooling shrinkage can be more closely wrapped outside frame 12.

A more detailed schematic view of the combination of the rim 12 and the mould 2 and the close fit of the slab 11 of plastic material is shown in figures 3B and 3C.

It can be seen from fig. 3C that the edge of the frame 12 is provided with a protrusion 123, the protrusion 123 protruding from the die 2 in a direction parallel to the extension of the sheet 1. In the cross-sectional view shown in fig. 3C, the protrusions protrude from the mold 2 in the longitudinal direction D1, but it is understood that protrusions protruding from the mold 2 in the transverse direction D2 may be provided on the longitudinal beams 121 of the rim 12. The plastic blank plate 11 after the plastic suction step covers the protrusion 123, the top surface, the side surface and the bottom surface of the plastic blank plate 11 and the protrusion 123 are tightly attached, and the protrusion 123 is embedded in the plastic blank plate 11 and cannot be detached from the plastic blank plate 11.

Fig. 4 shows the next step. In the step shown in fig. 4, the mould 2 is moved in a direction perpendicular to the direction of extension of the sheet 1 (in particular downwards in a third direction D3) to disengage the rim 12 and the slab 11. Since the projections 123 of the frame 12 are embedded in the plastic blank plate 11, the frame 12 cannot fall off the plastic blank plate 11.

A schematic view of the demolded plastic blank plate 11 is shown in fig. 5A and 5B. Referring particularly to fig. 5B, it can be seen that the plastic blank plate 11 covers the top and bottom surfaces of the protrusion 123, thereby restricting the bezel 12 from moving relative to the plastic blank plate 11 in the third direction D3. The frame 12 is also immovable relative to the plastic blank plate 11 in the transverse direction D2 and the longitudinal direction D1 due to the integral fit of the frame 12 and the plastic blank plate 11. The frame 12 cannot be removed from the sheet of plastic preform 11, and the sheet of plastic preform 11 is already formed as an integral part of the frame 12.

The next step is to shear-trim the sheet of plastic blank 11 so as to ensure at least that the trimmed sheet of plastic blank 11 covers the projection 123 of the rim 12, thereby ensuring that the rim 12 is embedded within the sheet of plastic blank 11. The finished panel 1 will be obtained after the trimming step is completed. Fig. 6A to 6C show detailed views of the prepared panel 1.

The trimming step comprises: the plastic blank plate 11 is cut along the cutting traces 112, as shown in fig. 6C, and the cutting traces 112 may be located on a portion of the plastic blank plate 11 that is attached to the bottom surface of the protrusion 123. This arrangement allows the plastic sheet material (i.e. the plastic blank sheet 11 after final forming) to include a portion on the bottom side of the protrusion 123 of the frame 12, which portion can support and limit the protrusion 123, thereby preventing the frame 12 from falling off relative to the plastic sheet material 1.

The sheet material 1 produced by the above-described steps may be applied to a box 3 as shown in fig. 7, for example, and the sheet material 1 may be formed as a side wall of the box 3.

Fig. 8 to 13C show a second embodiment according to the present invention. The second embodiment is similar to the first embodiment, and for the sake of brevity, the same or similar parts of the second embodiment as the first embodiment will not be described again.

Fig. 8 shows a first step in the method of manufacturing the sheet 4 in the second embodiment: the rim 42 is placed down in a third direction D3 on top of a mould 5 shaped to match the shape of the rim 42. The frame 42 comprises two longitudinal beams 421 and three transverse beams 422. Unlike the first embodiment, the die 5 in the second embodiment is not provided with a step, the frame 42 is fittingly wound around the die 5, and since the frame 42 has the transverse beam 422 at the intermediate position in the longitudinal direction D1, and the die 5 has the slit 53 corresponding to the transverse beam 422, the transverse beam 422 at the intermediate position can be fitted into the slit 53 of the die 5, so that the frame 42 and the die 5 are fitted into one separable whole. The top surface of the mold 5 is provided with a plurality of protruding ribs 54.

Fig. 9 and 10A show the next step in sequence: a plastic blank plate 41 is placed on the top surface of the mold 5 mounted with the frame 42, and suction is applied in a direction perpendicular to the extending direction of the plate 4 to mold the plastic blank plate 41 using a blister process such that the plastic blank plate 41 is coated on the frame 42 and the mold 5.

Fig. 10B and 10C show detailed views in fig. 10A. As can be seen in fig. 10C, the frame 42 has a protrusion 423 protruding outward relative to the mold 5 in a direction parallel to the extension direction of the sheet 4, and the blister-molded plastic blank sheet 41 tightly covers the protrusion 423, so that the frame 42 is fixed relative to the plastic blank sheet 41. Also, in the present embodiment, the top end of the inner wall 424 of the bezel 42 is fixed to the protrusion 423, and the bottom end of the inner wall 424 is free.

Fig. 11A shows the step of releasing the mold 5 downwardly from the plastic blank plate 41 and the rim 42 in the third direction D3, and fig. 11B and 11C show detailed schematic views of the plastic blank plate 41 and the rim 42 after demolding. As can be seen in fig. 11C, the projections 423 of the rim 42 are defined within the plastic blank plate 41 such that the rim 42 cannot be disengaged from the plastic blank plate 41. Also, after demolding, the free ends of the inner walls 424 of the bezel 42 do not contact any other components.

After demolding, a trimming step is to be carried out, and fig. 12A-12C show the trimmed plastic blank plate 41 and the mold 5. Referring to fig. 12C, the cutting trace 412 during trimming is formed on the portion of the plastic blank plate 41 located below the protrusion 423 and adapted to be attached to the outer side wall of the rim 42. The free ends of the inner walls 424 of the frame 42 now project downwardly beyond the cutting marks 412 of the plastic blank plate 41.

Preferably, with reference to fig. 13A-13C, the following operations will be performed after edging: the free end of the inner wall 424 is rolled outwardly and upwardly to shield the cutting traces 412 of the plastic blank plate 41. Referring to fig. 13C, the plastic blank plate 41 still covers the protruding portion 423 of the frame 42, and the inner wall 424 of the frame 42 is rolled outward and upward to cover the cutting trace 412 of the plastic blank plate 41. This arrangement allows the sheet material 4 to have a better appearance, and in use, the user cannot easily peel the plastic blank plate 41 off the frame 42 from the cutting marks 412, so that the connection between the frame 42 and the plastic blank plate 41 can be further ensured. In addition, the cutting trace 412 of the plastic blank plate 41 is shielded by the curled edge of the frame 42, and the cutting trace 412 is not easy to scratch a user, so that the product has a high safety factor.

Fig. 14 to 18C show a third embodiment according to the present invention. The third embodiment is similar to the first embodiment, and for the sake of brevity, the same or similar parts of the third embodiment as the first embodiment will not be described again.

Fig. 14 shows a first step of the method of manufacturing the sheet 7 in the third embodiment (the finished product of the sheet 7 is shown in fig. 19): the frame 72 is placed on top of a mould 8 having a shape matching the shape of the frame 72. The frame 72 has two longitudinal beams 721 and two transverse beams 722, the edge of the mould 8 is provided with a step 82 around the body 81 of the mould 8, and the frame 72 can be placed on the step 82.

Fig. 15 and 16A sequentially show the following steps: a plastic blank plate 71 is placed on the top surface of the mold 8 mounted with the frame 72, and suction is applied in a direction perpendicular to the extending direction of the plate 7 to mold the plastic blank plate 71 using a blister process such that the plastic blank plate 71 is wrapped on the frame 72 and the mold 8.

A schematic view of the combination of the plastic blank plate 71, the rim 72 and the mould 8 after the blister step is shown in fig. 16B and 16C, and with reference to fig. 16C, it can be seen that the plastic blank plate 71 abuts against the top and side surfaces of the combination of the rim 72, the mould 8 to encase it. Since the protruding portion 723 of the bezel 72 in the present embodiment has a circular arc-shaped cross section, it can be understood that the protruding portion 723 has no edges and thus has a good tactile feel. A sheet 71 of plastics material moulded by suction moulding is applied against the protrusion 723 to confine the rim 72 with the protrusion 723 therein.

Fig. 17A shows the step of releasing the mold 8 downwardly from the plastic blank plate 71 and the rim 72 in the third direction D3, and fig. 17B and 17C show detailed schematic views of the plastic blank plate 71 and the rim 72 after demolding. As can be seen in fig. 17C, the protrusion 723 of the rim 72 is defined within the plastic blank plate 71 such that the rim 72 cannot be disengaged from the plastic blank plate 71.

After demolding, a trimming step is to be carried out, fig. 18A-18C showing the trimmed plastic blank plate 71 and the mold 8. Referring to fig. 18C, the cutting trace 712 during trimming is a portion of the plastic blank plate 71 located below the protrusion 723 and configured to be attached to the outer sidewall of the rim 72, so that at least the trimmed plastic blank plate 71 is ensured to cover the protrusion 723 of the rim 72, thereby ensuring that the rim 72 is embedded in the plastic blank plate 71.

In the third embodiment, the top surface of the mold 8 is a wave-shaped round surface, so that the top surface of the resulting plate 7 is also formed into a wave-shaped round surface.

Fig. 19 shows a piece of furniture, such as a chair 9, to which the sheet 7 can be applied, manufactured by the method according to the third embodiment.

The method for manufacturing the plate provided by the utility model can keep the metal frame in the plastic plate after the plastic suction is finished, so that the plate manufactured by the plastic suction has smooth appearance and good strength. In subsequent use, the plate is not easy to deform, so that the service life of the plate can be prolonged.
