Description

塑料靠背椅
技术领域
本发明涉及椅子,特别是涉及一种塑料靠背椅,属于家具领域。
背景技术
    椅子是一种常用的家具,种类繁多,传统椅子有木椅、竹椅、藤椅和钢木混合椅等,上述椅子的加工工序多,制造比较麻烦,所以近年来广泛应用塑料椅。现有塑料椅大多为一次整体注塑(或吹塑)成型,具有加工省力,式样变化多,不怕雨水,可回收等特点。但已有塑料椅却存在着如下缺点:一是强度较差,由于一次性注塑,其中椅脚、椅背等部位既不宜太厚,太厚注塑时会出现缩孔等问题,薄了牢度低;二是式样呆板,不灵巧,不美观;三是色彩单调,通常为单色;四是透气性差;五是坐着不舒服。
发明内容
本发明的目的是为了克服已有技术的缺点,提供一种结构灵巧,式样美观,强度好,透气性强,坐着舒服的塑料靠背椅。
本发明塑料靠背椅的技术方案是:包括椅座、椅脚和椅靠背,其特征在于所述的椅座包括边框和座板,所述的边框制有向外伸出的横梁,通过横梁连接椅脚,椅脚为四根,两根后椅脚向上延伸为椅靠背的主杆,两根主杆制有一体的弧形上弓条和下弓条,上、下弓条与两根主杆中设置靠背板,所述的靠背板和座板上各制有仿藤的凸筋和凹槽,所述的椅脚、横梁、边框、主杆和上下弓条各自由外层和外层中的芯层所组成。
本发明公开了一种塑料靠背椅,在产品设计上将椅座、椅脚和椅靠背介分得非常清晰,由横梁连接成一个整体,结构十分灵巧、明晰高雅,又节省材料;其椅脚、横梁、边框、主杆和上下弓条各自包括外层和芯层组成,使各自构造粗壮,生产时,采用水平旋转二次注塑技术,不缩孔、充满型腔,产品强度好,很牢靠,又大方、美观;靠背板和座板上制有仿藤条的凸筋和凹槽,人坐着时透气、舒适。
本发明的塑料靠背椅,所述的座板和靠背板分别由两种以上不同颜色的塑料材料所制成。采用双色或者三色注塑机,进行两次或者三次注塑成型,增加塑料椅发的美观,提高产品档次。所述的芯层为发泡塑料层。在椅脚、横梁、边框、主杆和上下弓条中有了发泡塑料层,一是进一步提高产品强度,二是减轻重量。所述的边框为椭圆形。边框就是椅座的边缘,椅座的边缘制成椭圆形造型精巧,有灵气,强度好。所述的横梁两头通过圆弧R过渡分别连接边框和椅脚。横梁与边框和椅脚的连接处通过圆弧R过渡提高连接强度,增加美观。还可以是在所述靠背板和座板的上表面各制有仿藤的凸筋和凹槽,但靠背板和座板的背面为平面,外观新颖。
附图说明

图2是本发明塑料靠背椅的俯视示意图;
图3是本发明的靠背板和座板的背面为平面示意图。
具体实施方式
本发明涉及一种塑料靠背椅,如图1—图3所示,包括椅座2、椅脚1和椅靠背3,其特征在于所述的椅座2包括边框21和座板22,所述的边框制有向外伸出的横梁211,通过横梁211连接椅脚1,椅脚为四根,两根后椅脚向上延伸为椅靠背的主杆32,两根主杆制有一体的弧形上弓条31和下弓条34,上、下弓条与两根主杆32中设置靠背板30,所述的靠背板30和座板22的上表面各制有仿藤的凸筋33、23和凹槽35、24,所述的椅脚1、横梁211、边框21、主杆32和上下弓条31、34各自由外层4和外层中的芯层5所组成。本方案在产品设计上将椅座、椅脚和椅靠背介分得非常清晰,由横梁连接成一个整体,结构十分灵巧、明晰高雅,又节省材料;其椅脚、横梁、边框、主杆和上下弓条各自包括外层和芯层组成,使各自构造粗壮,生产时,采用水平旋转二次注塑技术,即在注塑时,先将椅脚1、横梁211、边框21、主杆32和上下弓条31、34的芯层5注塑成型,再注塑椅脚1、横梁211、边框21、主杆32和上下弓条31、34的外层4,然后加工模具水平旋转,采用双色注塑头对两种以上不同颜色的座板和靠背板进行二次注塑,这样加工原料能充满型腔,产品不缩孔,强度好,很牢靠,又大方、美观;靠背板和座板上制有仿藤条的凸筋和凹槽,人坐着时透气、舒适。所述的座板和靠背板分别由两种以上不同颜色的塑料材料所制成。采用双色或者三色注塑机,进行两次或者三次注塑成型,增加塑料椅发的美观,提高产品档次。所述的芯层5为发泡塑料层。在椅脚、横梁、边框、主杆和上下弓条中有了发泡塑料层,一是进一步提高产品强度,二是减轻重量。所述的边框21为椭圆形。边框就是椅座的边缘,椅座的边缘制成椭圆形造型精巧,有灵气,强度好。所述的横梁211两头通过圆弧R过渡分别连接边框21和椅脚1。横梁与边框和椅脚的连接处通过圆弧R过渡提高连接强度,增加美观。还可以是在所述靠背板30和座板22的上表面各制有仿藤的凸筋33、23和凹槽35、24靠背板30和座板22的背面为平面6,外观新颖。
