Rate of deceleration is an important factor in determining the severity of injuries, such as head and neck injuries, possibly sustained when participants collide with a wall assembly while playing, for example, ice hockey. The described wall assemblies each include a support assembly and a movable wall assembly supported by and movable with respect to the support assembly. Telescoping parts of the movable wall assembly enable deflection of the movable wall assembly to complex angles with respect to the support assembly. In addition, movable wall assemblies can be couple such that impact on one wall assembly can cause deflection of an adjacent wall assembly. Covers, shields, and spacers can be positioned to decrease gap formation during deflection of the movable wall assembly to reduce the risk of pinch points.

A training device for use with a goal having a pair of posts and a crossbar, includes a pair of side panels, each side panel being disposed adjacent each of the pair of posts, each side panel including a pair of first arms disposed parallel with the pair of posts, upper and lower transverse members extending between the pair of first arms, a first netting covering the area defined by the pair of first arms, and the upper and lower transverse members, and at least one hinge coupling one of the first arms to an adjacent post.

An inflatable portable ledge apparatus comprises an inflatable platform having a plurality of transverse baffles and a plurality of longitudinal baffles. There are a plurality of suspension straps connected to the inflatable platform. The suspension straps are connected the inflatable platform so that a load on the inflatable platform is distributed across all the suspension straps when the portable ledge apparatus is anchored at a single point.

Trampolines may include a frame, a bounce mat coupled to the frame, and a plurality of poles coupled to the frame. A cover may be disposed over at least a portion of the bounce mat and retained in an at least partially suspended position utilizing the plurality of poles. Trampoline may be utilized by coupling a bounce mat to a frame. A plurality of poles may also be coupled to the frame. A cover may be disposed over at least a portion of the bounce mat utilizing the plurality of poles to retain the cover suspended over the at least a portion of the bounce mat. Other aspects, embodiments, and features are also included.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, coordinate dynamic adjustments of a trailer based in part on a user profile associated with a user physically present at the trailer and an activity profile associated with an activity selected to be performed at the trailer. A dynamic adjustment may modify a tilt of a lower surface of the trailer. A dynamic adjustment may modify a dimension(s) of the trailer based in part on a detected object(s). Various dynamic adjustments may occur concurrently, individually and/or sequentially. The trailer may be a moveable trailer for temporary attachment with a vehicle.

An apparatus or system for enhancing an edge of a sporting court may include a first surface configured to engage with a surface of the sporting court and a second surface coupled to the first surface and configured to receive a ball and retain the ball in engagement with the second surface. The second surface may comprise a plurality of sub-surfaces, wherein one of the sub-surfaces may comprise a radial curve or at least one peak and at least one trough. The apparatus may comprise a retaining mechanism configured to retain at least one of the first surface or the second surface adjacent a court edge barrier.

A user interface includes a plurality of pass receipt locations rendered at spaced positions on or adjacent to the rendering of a three-point line to correspond with pass receipt locations on a basketball playing surface. Each pass receipt location is individually and directly selected by physical touch to define a custom basketball practice arrangement which is programmed into a control system to cause an ejector mounted to a frame to launch at least one basketball to each selected location.

Systems and devices for a team game played on an obround court includes radially symmetric barriers defining cylindrical goals having circular openings concentric with the semicircles of the obround court. An annular halt zone extends around the barriers. A free throw line extends around each halt zone. An obround judge lane extends along the perimeter of the court and is occupied by two judges or referees that monitor the game, while another judge or referee remains inside the perimeter. The court is divided by a centerline which includes a circle at the center of the court. The outer wall of the barrier includes one or more video screens. Audience members can access a computer network to display images, text or video selected by them in real-time during gameplay. The ball used for the game has a surface texture provided by a plurality of square pebbles instead of rounded pebbles.

A foldable basketball stand has at least one hoop on a rear end surface of a backboard on an upper half portion of a front frame. A middle portion of left/right front rod of the front frame has two first left/right joints respectively. Rear/front ends of a left-top rod and a left-bottom rod of a left frame are connected to a left-middle rod/the left-front rod respectively. Rear/front ends of a right-top rod and a right-bottom rod of a right frame are connected to a right-middle rod/the right-front rod respectively. Two ends of left/right supporting rod are connected to a middle portion of the left/right top rod and the left/right front rod respectively. An upper half portion of a rear frame has a stop portion. Left/right sides of the rear frame are connected to the left/right middle rods through left/right connecting rods respectively.

A universal trampoline backboard mount has a backboard. The backboard includes a hoop connection configured for receiving a basketball hoop. A right post has a right post upper connector and a right post lower connector. A right upper line connects to the right post upper connector. The right upper line connects to the backboard. A right lower line connects to the right post lower connector. The right lower line connects to the backboard. The right lower line is mounted below the right upper line. A right enclosure pole adapter connects the right post to an upper end of a right enclosure pole. A left post has a left post upper connector and a left post lower connector. A left upper line connects to the left post upper connector and the right side is symmetrical to the left side.
