Abstract

在一种具有靠弹簧装置作用、使靠背向后倾斜座椅(1)中，弹簧装置有一片簧(20)，片簧(20)的中央部分可操作地与座椅的底脚结构连接，而其两端则与支撑靠背的两个侧臂(4a)连接。

Description

可调整靠背斜度的椅子
                    技术领域
本发明涉及这样一种类型的各种座椅，它们由底脚结构、该底脚结构支撑的座子、靠背和弹簧装置构成。其中的靠背具有安装在所说底脚结构上的支承结构，以使靠背可绕一横向水平轴转动，因而可在相对垂直的位置和向后斜倚的位置之间运动，而所说的弹簧装置可使所说的靠背倾向其垂直位置。
                    背景技术
近些年来，已经有越来越多的研究从事提供各种座椅，其特征在于这些座椅，甚至包括在公共场所，例如，影院、剧院、礼堂或者会议室和会谈室等处使用的座椅，从人类工程学的角度来看，能为人们提供正确的和最大程度舒适的坐姿。不用说，这种类型座椅的结构当然必定是简单的，而且造价是低廉的。因此，已经迫使设计者们，在上面提及的对立的要求之间寻求各种折衷方案。但至今找到的方案是不十分满意的。
                    发明内容
申请人从这样的考虑出发，即甚至对在公共场所使用的座椅，也一定要以类似于通常在办公室使用的座椅的方式，提供能弹性地倾向垂直位置的可调整斜度的靠背。
因此，本发明的目的在于提供一种在本说明书开始部分指出的那种类型的座椅，一方面满意地解决上面提及的问题，以便特别有助于应用在公众使用的各种座椅的座子方面，另一方面，甚至能够有助于在不同的场所，例如，办公室座椅或家庭座椅的使用。
鉴于为达到上面指出的目的，本发明提供一种座椅，它由底脚结构，该底脚结构支撑的座子、靠背和弹簧装置构成。其中的靠背具有安装在所说底脚结构上的支承结构，以使靠背可绕一横向水平轴转动，从而可在相对垂直的位置和向后斜倚的位置之间运动，而所说的弹簧装置可使所说的靠背倾向其垂直位置。这种座椅的特征在于所说的弹簧装置，它具有一个片簧沿所说靠背支承结构的所说转动轴安放，并且其中央部分，可操作地与所说底脚结构连接，而其两端与所说靠背支承结构连接。
所说片簧的每半部分起扭力杆的作用，它在片簧的中央部分与底脚结构刚性连接，而片簧相应的端部则与所说靠背相连。因此，这样的安排，提供了两个分别与靠背的两侧相联系的扭力杆的效果，从而具有结构极为简单和造价低廉的优点，同时安装容易且快捷。
在本发明的实施例中，底脚结构包括一管状截面构件，其中安置有所说的片簧。所说的管状截面构件，在其中央至少有一内部阻挡部分，用来限制片簧的转动。靠背支承结构有两个侧臂，它们有两个安装在所说管状截面构件相对端内的可转动同轴销钉。每个锁钉及装有阻挡装置的管状截面构件的相应端相互配合，以便限制所说销钉相对于分别和靠背的垂直位置及向后斜位置相应的两个极端位置之间的管状截面构件的倾斜角位移。所说的安置是这样的，即当靠背处于其垂直位置时，片簧的每半部分承受扭转载荷，从而趋使靠背保持在垂直位置。
另外，在所说的最佳实施例中，管状截面构件由板材金属弯成的管子构成，在其中央有两个沿直径方向相对的区域。这两个区域向内变形，当靠背向后倾斜时，片簧的中央部分靠着向内变形的区域。再有，相互配合的管状截面构件的端部和安装在这样的端部内可转动的各自的销部之间的所说阻挡装置，对管状截面构件的每个端部而言，有一个由所说销部支承的横向构件，并且每个端部接合在管状截面构件壁上形成的圆周切口内。
当然，上面描述的机构适用于许多不同类型的座椅。
下面参照附图的说明，将使进一步的实施例和结构的细节变得明显起来，而给出的实施例完全没有限制作用，其中：

                 具体实施方式
现在参照图1，2，数字1通常指定一有底脚结构2的座椅，该底脚结构支撑着座子3和靠背4。底脚结构2由两根弯曲的彼此焊接的管件5、6构成，并分别限定了两条前腿7和两条后腿8。两个管件5，6的每一个都具有通常U状外形。管件5有两翼和中间部分9(图2)，其中的两翼限定座椅的前腿7，而中间部分9则在其转弯处在水平面内呈U形弯曲，座子3就固定其上。 U形构件6具有限定后腿8的两翼和与构件5在其两端部11处焊接的中间直的部分10，在图2中可以看见一个端部11。中间直的部分10刚性地支撑在悬臂状的两个端衬套12内(图3、4)，而在衬套12里面有板材金属13制成的管状截面构件的焊接的端部，因此，该管状截面构件刚性地与座椅的底脚结构连接。
座椅的靠背4装有支承结构，该支承结构由两个侧臂4a构成。每个侧臂4a的端部有一销钉14，该销钉可转动地安装在管状截面构件13的相应端，而该管状截面构件带有一个具有低摩擦的塑性材料制成的插入衬套15。每个销钉14由横向构件16阻挡，而横向构件16，以其两端接合在各自衬套12上形成的圆周切口17之中，因此，靠背4绕管状截面构件13的轴18的倾斜角位移，被限制在分别相应于靠背的相对垂直位置和向后斜倚位置这两个终极位置之间。这两个终极位置，在图1中分别用实线和虚线加以表示。在图3中，参考数字99指定一个用来锁紧横向构件16的螺旋，而该螺旋接合在靠背的每个侧臂4a之中。
使靠背倾向其垂直位置的弹力，由放置在管状截面构件13内的由片簧20构成的弹簧装置获得，而片簧20的两端放在销钉14的切口21中，且切口21自销钉14的端面轴向形成。板材金属制成的管状截面构件13，其中间部分有两个径向朝内变形的区域，彼此沿直径方向对置，并在图2a中用参考数字22指定。当靠背4向后倾斜时，片簧20的中间部分靠着所说的变形区域。将每个横向构件16，放置在相应的圆周切口17中的这种安排，使得片簧20受到一趋使将靠背4保持在其竖起位置的载荷。当就座的人靠在靠背上时，他施加一推力，靠着片簧20的作用，趋使靠背向后倾斜，该片簧相当于一对在片簧的中央与底脚结构刚性连接的扭力杆，而且分别与支持靠背的两个侧臂4a连接。
从前面的描述十分明显，这种座椅的特征在于，具有极为简单的结构，因此能够用低廉的费用制造、容易和快速的安装，同时保证获得十分舒适和从人类工程学角度看来是正确的坐姿。
图5-14表示按照本发明的座椅的进一步的实施例。在这些图中，与图1-4中的座椅相对应的那些部分，用相同的参考数字表示。在这个实施例的情况中，座椅的底脚结构由两侧的直立部分30构成。在直立部分30的下端，有两个通常用倒置的T状外形限定的侧脚31。两个直立部分30，靠横跨构件33在它们的上端彼此相连。如在图9、11中可以看到的那样，直立部分30和横跨构件33，由板材金属制成的具有椭圆和平整截面的管子构成。横跨构件33有两个成肱梁样的附属部分34，自与支承衬套12(类似于根据图1-4解说的衬套)的横跨构件的两端相邻的两个区域伸出。在衬套12中有焊接的管状截面构件的端部。支撑靠背4的侧臂4a的配置、在管状截面构件13中的片簧20，和在侧臂4a上的销钉14以及可转动地安装在管状截面构件13的端部的侧臂4a，是与根据图1-4描述的同类物相类似的。
再有，在图5-19中表示的实施例的情况下，座子3的结构呈可转动地安置在管状截面构件13的中间部分之上，因此，座子3可在正常使用的位置(图5)和基本上升至垂直的位置(图8)之间活动，以便使得在公众场所和会议室的同一类型的两排相邻座椅间行走的人们容易通行。座椅的操作完全与根据图1-4的座椅描述的操作情况相类似。
附图的图15-19示出了许多同一类型的座椅彼此向上重叠在一起，同时又占据最小空间的可能性，  或者将同一类型的大量座椅相互前后安放，使座子处在其竖直位置成为可能。
从前面的描述，十分明显，本发明目的形成的机构，可容易地适用于各种类型的座椅，而且特别能使生产的座椅，从舒适的观点出发，一方面具有非常优良的性能，另一方面，结构十分简单，而且费用低廉。
