Foldable yoga brick

The yoga brick comprises panels forming a quadrilateral tube, and the panels are secured to each other by hinges such that the tube can be folded. End caps are secured to both ends of the quadrilateral tube and engaged with the quadrilateral tube so as to resist folding when in place. The panel may define a convex portion that engages a concave portion on an edge of the end cap. A magnet in the end cap may engage with the hinge to secure the end cap in place. Rotating or sliding tabs may also be used to lock the end cap. The inner surfaces of the top and bottom panels may define a slot for receiving a weight plate. The end cap may be secured to the panel by a hinge. The hinge for fixing the panel or the end cover can be a double hinge. 瑜伽砖包括形成四边形管的面板，且面板通过铰链彼此固定，使得管可以折叠。端盖固定至四边形管的两端，并与四边形管接合，从而在就位时抵抗折叠。面板可以限定与端盖的边缘上的凹部相接合的凸部。端盖中的磁体可以与铰链接合，以固定端盖就位。旋转或滑动凸片也可用于锁定端盖。顶部和底部面板的内表面可以限定用于接收配重板的槽部。端盖可以通过铰链固定至面板。固定面板或端盖的铰链可以是双铰链。
