A basketball hoop with folding function, comprising a basket frame and a folding structure, the folding structure comprises a mounting plate, a folding plate, a rotating shaft, a torsion spring and a support rod; the folding plate comprises a backboard, and a first side board, the mounting plate comprises a fixed board and a second side board, and the rotating shaft passes through the first and second side board and rotating connected, the torsion spring is sleeved outside the rotating shaft, and comprises a first spring body, a second spring body, a toggle rod, a first spring torsion bar and a second spring torsion bar. Its advantage is that the basketball hoop can be folded and unfolded, which is convenient for use.

A hydraulic cylinder assembly for operating a weight lifting bench and other equipment. The hydraulic cylinder assembly comprises a hydraulic cylinder containing a hydraulic fluid, an accumulator containing a pressurized compressible fluid, and a flow control valve assembly interposed in a flow path therebetween. The flow control valve includes an axially reciprocating piston defining a flow control orifice and an axially movable plunger received in the orifice. Movement of the plunger operates to engage and open a ball check valve which in turn opens the flow path allowing hydraulic fluid to flow from the hydraulic cylinder to the accumulator. The working end may be stepped and positionable between first and second axial positions relative to the orifice to define first and second flow areas via movement of the plunger. Reciprocating movement of the piston opens and closes the flow path.

A foldable treadmill includes a treadbase having two short sides and two long sides, a base frame extended in the extending direction of the short sides of the treadbase and supported on a supporting surface, a linkage unit coupled between the treadbase and the base frame, and a retractable unit including a pivot-connection portion pivotally connected to the base frame and a retractable member interlocking with the linkage unit and movable relative to the pivot-connection portion between a retracted position where the long sides of the treadbase are disposed in proximity to the supporting surface and an extended position where the long sides of said treadbase are disposed far from the supporting surface and the position of the linkage unit is shifted with the retractable member to reduce the clearance between the linkage unit and the treadbase to minimize space occupation.

A treadmill includes a frame, a driving member and a running belt. The frame includes a base, a front rotating shaft and a rear rotating shaft. The driving member has a motor and a transmission member drivable by the motor. The motor is installed between the front rotating shaft and the rear rotating shaft and is located adjacent to the front rotating shaft. The transmission member is adapted for driving the front rotating shaft to rotate. The running belt winds around the front rotating shaft and the rear rotating shaft, and is drivable by the motor to rotate relative to the base. By installing the motor between the front rotating shaft and the rear rotating shaft, an overall length and size of the treadmill is reduced for minimizing storage space.

A retractable wall mounted exercise rack system for providing an exercise rack that may be easily and compactly stored when not in use. The retractable wall mounted exercise rack system generally includes one or more brackets attached to a wall, a pair of support members, and a plurality of arms pivotally extending from the brackets and pivotally connecting to the support members. One or more actuators are connected between the brackets and the arms to assist in lifting the structure into a compact retracted position for storage.

A retractable sport screen is described. The sport screen includes a head roll mountable to a structure and a screen couplable to the head roll tube being movable between a first position and a second position. The screen is rolled up around the head roll tube when in the first position and extended towards a ground when in the second position. The screen further includes a middle bar received in a first pocket of the screen and spaced from the head roll when the screen is in the second position, a bottom bar received in a second pocket of the screen and spaced from the middle bar in a direction away from the head roll when the screen is in the second position, the bottom bar being weighted to provide tension to the screen to inhibit a launched projectile striking the screen from contacting the structure when the screen is in the second position, and a mounting assembly for mounting the head roll to the structure.

A retractable basketball hoop comprising a backboard, a basketball rim, a pole to support the backboard at an elevation, a motor in communication with the pole and a controller, with a user interface, in communication with the motor for adjusting the elevation of the backboard. The basketball rim is pivotally coupled to the backboard.
