Abstract: A quickly collapsible and erectable horizontal and parallel bars combination mainly includes two modularized upright assemblies, two side supports detachably connected to a top of the upright assemblies, and a top bar detachably supported on and between upper ends of the two side supports. Each of the upright assemblies includes two upright posts, upper and lower crossbars fixedly connected to predetermined positions on the two upright posts, a U-shaped handgrip and a framed foot member pivotally connected to the upper and the lower crossbar, respectively, and supporting posts vertically connected to and extended between the handgrip and the framed foot member. The handgrip and the framed foot member may be synchronously pivotally turned upward to collapse the upright assembly to an almost flat state and accordingly a largely reduce volume.

Abstract translation: 快速可折叠和可竖立的水平和平行杆组合主要包括两个模块化直立组件，两个侧支撑件可拆卸地连接到直立组件的顶部，以及可拆卸地支撑在两个侧支撑件的上端之间且位于两个侧支架的上端之间的顶杆。 每个直立组件包括两个直立柱，上和下十字杆固定地连接到两个立柱上的预定位置，U形手柄和分别与上横梁和下横梁相连的支承柱 垂直连接并在手柄和框架脚部件之间延伸。 手柄和框架的脚构件可以同步地向上转动以将直立组件折叠成几乎平坦的状态，并因此大大减小体积。

Abstract: A folding recliner includes an extendable frame, a rear frame, a backrest frame, and a seat frame that have sequentially reduced widths. The rear frame is pivotally connected at two lower ends to two rear inner sides of the extendable frame, the backrest frame has two hooked upper ends for detachably engaging with one of many crossbars of the rear frame, the backrest frame is pivotally connected at lower ends to rear ends of the seat frame, and front ends of the seat frame are pivotally connected to two front inner sides of the extendable frame and a U-shaped leg. Therefore, when the recliner is fully folded, the rear frame, the backrest frame, and the seat frame are sequentially nested in the extendable frame to locate in the same plane, enabling the folded recliner to occupy the smallest possible space.

Abstract translation: 折叠躺椅包括具有顺序减小的宽度的可延伸框架，后框架，靠背框架和座椅框架。 后框架在两个下端枢轴连接到可延伸框架的两个后内侧，靠背框架具有两个钩形上端，用于可拆卸地与后框架的许多十字形杆中的一个接合，靠背框架在下端枢转连接 到座椅框架的后端，并且座椅框架的前端可枢转地连接到可延伸框架的两个前内侧和U形腿部。 因此，当躺椅完全折叠时，后框架，靠背框架和座椅框架顺序地嵌套在可延伸框架中以定位在同一平面中，使得折叠的躺椅能够占据尽可能小的空间。

Abstract: A horizontal bar includes two side supports, a top bar, and a swing member. The side supports are provided at upper ends with two symmetrical locating holes, through which two outer ends of the top bar are extended to thereby connect the top bar to the side supports. The swing member includes horizontally paralleled upper and lower bars connected to each other via a plurality of connecting plates vertically extended between the upper and lower bars. The upper bar is a hollow tubular member put around the top bar, and the lower bar is covered with a sleeve. The horizontal bar includes simple parts that can be easily assembled and disassembled, and can be connected to other types of sporting goods for more kinds of exercises.

Abstract translation: 水平杆包括两个侧支架，顶杆和摆动构件。 侧支撑件在上端设置有两个对称的定位孔，顶杆的两个外端延伸通过该定位孔，从而将顶杆连接到侧支撑件。 摆动构件包括通过在上杆和下杆之间垂直延伸的多个连接板彼此连接的水平并列的上杆和下杆。 上杆是围绕顶杆放置的中空管状构件，下部杆用套筒覆盖。 水平杆包括易于组装和拆卸的简单部件，并且可以连接到其他类型的运动用品以进行更多种类的锻炼。

Abstract: A sectional horizontal bar mainly includes two H-shaped uprights, two A-shaped bar supports connected to upper ends of the uprights, two curved bases connected to lower ends of the uprights to extend forward and rearward from the uprights for the latter to stably stand, and a top bar connected at two ends to upper ends of the bar supports. A lower and an upper D-shaped support are pivotally connected to lower ends and upper portions of each upright to normally locate at outer sides of the two uprights. When the two D-shaped supports are pivotally turned to locate at inner sides of the two uprights, a user may grip with two hands at the two inward turned upper D-shaped supports to do exercises just as on parallel bars.

Abstract translation: 截面水平杆主要包括两个H形立柱，两个连接到立柱的上端的A形杆支撑件，两个弯曲基座连接到立柱的下端，从立柱向前和向后延伸，以使后者稳定站立 ，并且在两端连接到杆支撑件的上端的顶部杆。 下部和上部D形支撑件可枢转地连接到每个直立件的下端和上部，以正常定位在两个立柱的外侧。 当两个D形支撑件枢轴转动以定位在两个立柱的内侧时，用户可以用两只手握住两个向内转动的上部D形支撑件，以像平行杆一样进行锻炼。
