Abstract

坐椅和桌子的十字支架(1)由四根按一定角度布 置在一个平面内的硬木方(4)组成，硬木方最好用山 毛榉，其连接端(5)用鸠尾榫(6)连接成一个具有不同 角度(α，β)的十字，并用胶粘合。连接件(7)用来牢 固连接四根木方(4)的连接端，并由上紧固件(8)和下 紧固件(9)组成。连接件(7)的上紧固件(8)和下紧固 件(9)在相应的孔(10)中牢固连接木方(4)的连接端 (5)，并用螺丝与木方(4)连接。连接件(7)的上紧固 件(8)和下紧固件(9)最好用连接钢板。

Description

本发明涉及的是坐椅和桌子的木十字支架。
美国专利US-PS1    744    799提出了一种木椅子，其框架由一个用螺丝与坐板拧紧的十字支架、四条用螺丝与十字支架的两根搭接木方拧紧的椅子腿，以及一个加固椅子框架用的十字形腹板结构组成，腹板结构的两块搭接腹板用螺丝与椅子腿的下部拧紧。由于搭接处的切口深度相当于一半的木方高度或腹板高度，因而两根木方和两块腹板的强度都受到了削弱。由于十字支架的抗弯和抗扭强度不够，必须适当加厚坐板，从而使坐板变硬。这样的椅子缺少坐的舒适感。为了增加十字腹板结构的强度，在搭接处两块腹板上边固定了一块带角支撑的加固板，用角支撑把腹板包住。
在锯这种椅子十字支架用的长木方和十字腹板结构用的长腹板时，由于木节、节孔等原因而产生相当多的下脚料。因此，这种椅子由于十字支架和十字腹板结构需要大量木材而造成批量生产太贵。
市场上带十字支架的木坐椅和桌子也有这个缺点，其十字支架由一根长木方和两根短木方组成，短木方与长木方用木钉固定。
上述已知的十字支架由于结构上的原因而引起的垂直和水平力所产生的弯曲应力和扭转应力可能造成木质连接元件（尤指木钉）破坏；此外，十字支架的木方超过一定长度的椅子框架和桌子框架都是不稳定的。
德国专利DE3708991C1提出了堆叠式坐椅和沙发椅用的一种支承框架，其前后框架和两侧框架都用木材。前框架两端用直榫与椅子的两条前腿连接，且端部范围用榫与两侧框架连接。后框架由两个位于一个平面的V形支架组成，该支架的外端用榫与椅子的两条后腿连接；此外，这两个支架的外露段分别用榫与一个侧框架连接，而其逐渐过渡成尖状的里端则用榫倾斜连接到一块中间腹板上，中间腹板的中部与两侧框架连接。
这种复杂的框架结构以其需用大量木材而相当昂贵。
本发明的任务是，提出一种结构简单、稳固而且价廉的坐椅和桌子用的木十字支架。
本发明的任务是这样解决的，椅子和桌子的木十字支架，其特征是，木十字支架（1）由4根木方（4）组成，木方的里端（5）用一个连接件（7）相互牢固连接成一个具有相同或不同角度（α，β）的十字，连接件（7）由一个上紧固件（8）和一个下紧固件（9）组成，上紧固件（8）和下紧固件（9）在孔10中牢固连接木方（4），并用螺丝与木方拧紧。
这个十字支架结构的其它有利的结构则在从属权利要求中述及。
本发明的十字支架具有如下优点：
用两块连接钢板或适当形状的塑料件作连接件把四根木方的里端牢固连接在一起，并用螺丝拧紧木方。这样，就可用四根短木方作十字支架，由于下脚料很少，所以短木方比上述已知的十字支架用的长木方便宜。通过最好由两块连接钢板或两个塑料件组成的连接件牢固连接四根木方的里端保证了椅架或桌架的必要抗弯和抗扭强度。最后，通过连接件的尺寸可确定木方的紧固孔长度，从而可根据椅子腿或桌子腿要求具有一定弹性对椅架或桌架的刚度产生影响（进行调节）。
下面用图中所示的一个实施例来说明本发明。
图1表示用新十字支架的椅子侧视图，
图2表示十字支架的立体展开图，
图3表示十字支架的俯视图，
图4表示图3的Ⅳ-Ⅳ剖面图，
图5表示十字支架的侧视图。
如图2～图5所示，带有一块平坐板3（见图1）的椅子2的十字支架1由四根按一定角度布置在一个平面内的硬木方4（最好用山毛榉）组成。木方里端即连接端5用鸠尾榫6连接成一个带有不同角度α、β的十字形，并用胶粘合。
连接件7用来牢固连接四根木方4的里端5，并由上紧固件8和下紧固件9组成。连接件7的上紧固件8和下紧固件9在相应的孔10中牢固连接木方4的里端，并用螺丝与木方4拧紧。
连接件7的上紧固件8和下紧固件9最好用连接钢板构成。两块相互对置的连接钢板可使作用到十字支架上的扭力相互抵消。
此外，连接件7的上紧固件8和下紧固件9也可用塑料件或铸件。
椅子腿12用木钉固定到十字支架1的木方4之自由端11上。
在十字支架1经过表面处理以后，把连接件7的上紧固件8和下紧固件9放到木方4的里端5上，并用市售木螺丝与木方拧紧。
十字支架经过变化的另一种结构形式是，四根木方4的里端相互拼在一起，并至少用两个螺丝与连接件7的上紧固件8和下紧固件9拧紧，如图3用参考符号5′表示的虚线所示。
