摘要： A chair includes a seat, a backrest and a frame to support the seat and backrest. The frame includes first and second supports disposed at first and second sides of the chair, respectively. The chair also includes a first engaging mechanism pivotally coupling the backrest with the first support, and a second engaging mechanism pivotally coupling the backrest with the second support. The first or second engaging mechanism includes first, second and third members. The first member fixedly is coupled with the backrest. The second member pivotally connects the first member of the respective engaging mechanism with the first or second support, thereby allowing the backrest to rotate along a first axis in the width direction of the chair. The third member is fixedly coupled with the first or second support and configured to limit the rotation of the backrest.

摘要： A folding joint mechanism for stackably collapsing elongated structural sections includes a plurality of substantially identical brackets pivotably interconnected and rotatable between an extended and a stowed configuration. In the extended configuration, the brackets abut each other against stop protrusions on the top outside surface of each bracket forming foldable extensions that are able to support significant weight by distributing the top. side force. In the stowed configuration, the brackets are compacted to a substantially stacked disposition whereby the brackets are aligned and directly adjacent to one another. The joint and bracket assemblies may be employed in elongated sections of various structures in which compactability may be advantageous for shipping, storage, and user transportation.

摘要： A foldable chair assembly includes a foldable frame, and a positioning unit. The foldable frame includes two auxiliary bars pivotally connected with each other. The positioning unit includes a first control lever having a first end pivotally mounted on one of the two auxiliary bars and a second end formed with a positioning channel, and a second control lever having a first end pivotally mounted on the other auxiliary bar and a second end detachably mounted in the positioning channel of the first control lever. Thus, the foldable frame is folded by pressing the second cover, so that the foldable frame can be folded by his one hand only, thereby facilitating the user folding the foldable frame.

摘要： A chair includes a seat frame, a pair of rear joint unit, a backrest frame, a pair of rear legs, a pair of front joint units, and a pair of front legs. The seat frame has a top side, a bottom side, front and rear ends, and two lateral sides which interconnect the front and rear ends. Each of the rear joint units has a first pivot member disposed above the seat to extend along a direction transverse to the lateral sides of the seat frame, and a second pivot member disposed below the seat frame to extend parallel to the first pivot member. The backrest frame is connected pivotally to the rear joint units via the first pivot members so as to be foldable over the top side of the seat frame. Each of the rear legs is connected pivotally to one of the rear joint units via the second pivot member so as to be foldable over the bottom side of the seat frame. Each of the front joint units has a third pivot member parallel to the second pivot member. Each of the front legs is connected pivotally to one of the front joint units via the third pivot member so as to be foldable over the bottom side of the seat frame.

摘要： A folding chair having a first, seat frame and a second, backrest frame, the frames articulated to supporting leg frames and lateral armrests. A cup member is secured to the rear ends of the seat frame, and the backrest frame is hinged to the cup member. A toggle element is pivoted to the cup member and to a rear leg of the chair, the toggle element being provided with a rest portion which comes to rest against the rear leg. A retainer in the form of a detent and a recess are provided on the cup member and on the toggle element, respectively, to prevent the rotation of the toggle element with respect to the cup member when the chair is open.

摘要： The present wheel chair, especially for invalids, is foldable in a verticalirection rather than horizontally to transform the chair into a very compact package. For this purpose all foldable components of the chair are equipped with journals having journal axes extending perpendicularly to a vertical central plane of symmetry of the chair. Further, the seat is vertically liftable and also horizontally guided on guide tracks (18) extending in parallel to the plane of symmetry of the chair. The guide tracks (18) are movable back and forth on guide rail sections (17) which are pivoted to the top of the support structure (4) of the chair. Hydraulic piston cylinder drives are connected to all chair components which are movable under a loaded condition with a person sitting in the chair. The chair seat is also divided so that the chair may be moved directly over a toilet seat, for example. By raising the chair seat sufficiently above the arm rests in the aisle of an aircraft or bus, a person may be transported directly to a passenger seat with the aid of the present chair.
摘要翻译： 目前的轮椅，特别是无门的轮椅，可以在垂直方向而不是水平折叠，以将椅子转换成非常紧凑的包装。 为此，椅子的所有可折叠部件装备有具有垂直于椅子的垂直中心对称平面延伸的轴颈轴颈的轴颈。 此外，座椅是可垂直升降的，并且在平行于椅子的对称平面延伸的导轨（18）上水平地引导。 引导轨道（18）可在导轨部分（17）上前后移动，导轨部分（17）枢转到椅子的支撑结构（4）的顶部。 液压活塞缸驱动器连接到所有椅子组件，可在负载状态下与坐在椅子上的人一起移动。 椅子座椅也是分开的，例如椅子可以直接在马桶座上移动。 通过将座椅足够地抬高到飞机或公共汽车的通道上的扶手上，可以借助于本椅子将人直接运送到乘客座位。
