網狀椅面及其製造方法以及具有網狀椅面的椅具 Reticulated seat surface, method for manufacturing the same, and chair equipment having the reticulated seat surface

本發明係有關一種網狀椅面及其製造方法以及具有網狀椅面的椅具，尤指一種以聚氨酯(PU)當3D列印材而利用3D列印方式以在一椅面框架之表面上列印成型至少一PU網面單元，藉以提昇該網狀椅面之製程效率及多樣化裝飾功能。 The invention relates to a mesh seat surface and a manufacturing method thereof, and a chair device having the mesh seat surface, in particular to a polyurethane (PU) as a 3D printing material and a 3D printing method to be used on the surface of a seat frame. Printing and forming at least one PU mesh surface unit, thereby improving the process efficiency of the mesh seat surface and various decorative functions.

3D列印技術及其應用已相當風行，但目前尚未見有將3D列印技術尤其以聚氨酯(PU)作為列印材之3D列印技術被應用在椅具尤其具有網狀椅面之椅具的領域中。現有技術製作一具有網面的椅背時，需先按照該款式之椅背框架之設計尺寸或形狀來開設模具(如射出成型模具或灌鑄模具)供用以製造一相搭配之椅背網面，也就是所製成之椅背網面只能提供給該款式之椅背框架專用，當更換另一款式之椅背時，即須另再開模製造，如此製程相當費時費工。此外，當一製作完成之椅背網面要組裝在一所對應之椅背框架上時，還須利用其他輔助配件，才能使該椅背網面與該椅背框架結合成一體，如此亦相對造成該額外輔助配件之成本增加。 3D printing technology and its application have become quite popular, but there is currently no 3D printing technology that uses 3D printing technology, especially polyurethane (PU) as a printing material, to be applied to chairs, especially chairs with a mesh seat surface. In the field. In the prior art, when making a seat back with a mesh surface, a mold (such as an injection molding mold or a casting mold) must be opened according to the design size or shape of the seat back frame of the style for manufacturing a matching seat back mesh surface. That is, the mesh of the back of the chair can only be provided for the back frame of this style. When replacing the back of another style, the mold must be opened again. This process is time-consuming and labor-intensive. In addition, when a finished seat back mesh is to be assembled on a corresponding seat back frame, other auxiliary accessories must be used in order to combine the seat back mesh with the seat back frame, which is also relative. As a result, the cost of the additional accessory is increased.

因此，在具有網狀椅面之椅具領域中，如何藉由現有的3D列印技術以直接使一椅背網面(但不限制椅背)與一椅背框架(但不限制 椅背)結合成一體上，以利於量產化、降低製作成本或增加市場競爭力，此乃本發明主要解決的課題，本發明即針對上述課題提供最有效且最有利的解決方案。 Therefore, in the field of chairs with a mesh seat surface, how to directly make a seat back mesh surface (but not limited to the seat back) and a seat back frame (but not limited to) by the existing 3D printing technology The seat back) is integrated into one body to facilitate mass production, reduce production costs, or increase market competitiveness.

The conventional seat surface material includes metal, plastic, wood, etc., but is not limited; the seat frame frame 10 can borrow other structures. Pieces or locking devices are assembled on a chair 3 to become a part of the structure of the chair 3 such as a seat back portion or a seat portion, but without limitation, the seat frame 10 has an outer frame portion 11.

此外，該椅面框架10亦可利用該3D列印裝置2並以聚氨酯(PU)31作為列印材但不限制，使該椅面框架10進一步能藉由該3D列印裝置2之噴頭40噴出聚氨酯(PU)31以列印成型如圖3、4、7、8所示。 In addition, the seat frame 10 can also use the 3D printing device 2 and use polyurethane (PU) 31 as a printing material, but is not limited, so that the seat frame 10 can be further ejected by the nozzle 40 of the 3D printing device 2 Polyurethane (PU) 31 is formed by printing as shown in Figs. 3, 4, 7, and 8.

該至少一PU網面單元30係利用至少一3D列印裝置2且以聚氨酯(PU)31作為該3D列印裝置2之列印材，而藉由該3D列印裝置2之噴頭40噴出聚氨酯(PU)31以在該椅面框架10之外框部11之一表面11a上及一相配合之支撐件20之一支撐面21上列印成型，並使該至少一PU網面單元30在列印成型時能與該椅面框架10之外框部11結合成一體。 The at least one PU screen unit 30 uses at least one 3D printing device 2 and uses polyurethane (PU) 31 as the printing material of the 3D printing device 2, and the polyurethane 40 is ejected by the nozzle 40 of the 3D printing device 2 ( PU) 31 is printed on one surface 11 a of the outer frame portion 11 of the seat frame 10 and one supporting surface 21 of a supporting member 20, and the at least one PU mesh unit 30 is arranged in a row. It can be integrated with the outer frame portion 11 of the seat frame 10 during printing.

該支撐件20可視為該3D列印裝置2在進行列印工作時所用之輔助治具，該支撐件20係可裝卸地裝設於該椅面框架10之結構體中，該支撐件20之主要作用是使該椅面框架10之外框部11之一表面11a能與該支撐件20之一支撐面21保持或形成一平順面，例如該支撐件20可裝卸地安裝於該椅面框架10內如填塞在該外框部11的一中空空間14中如圖2-4、6-8所示但不限制，藉此該3D列印裝置2之噴頭40能在所形成的平順面(11a，21)上順利地進行列印工作。當該至少一PU網面單元30列印並一體成型於該椅面框架10上時，該支撐件20即可自該椅面框架10內移除如圖1、5、9、10所示。 The supporting member 20 can be regarded as an auxiliary jig used by the 3D printing device 2 when performing printing work. The supporting member 20 is detachably installed in the structure of the seat frame 10. The main function is to enable a surface 11a of the outer frame portion 11 of the seat surface frame 10 to maintain or form a smooth surface with one of the support surfaces 21 of the support member 20. For example, the support member 20 is detachably installed on the seat frame. The inside 10 is filled in a hollow space 14 of the outer frame portion 11 as shown in FIGS. 2-4 and 6-8 but is not limited, whereby the nozzle 40 of the 3D printing device 2 can be formed on the smooth surface ( 11a, 21). When the at least one PU mesh unit 30 is printed and integrally formed on the seat frame 10, the support member 20 can be removed from the seat frame 10 as shown in FIGS. 1, 5, 9, and 10.
