A tennis net anchoring device and method securely anchors a tennis net center strap to a recessed anchor post on a tennis court surface. The anchoring device comprises a longitudinal, double-sided, unitary body supporting a net-retention member and a ground-retention member. A top portion of the unitary body includes two arcuate T-shaped, net-retention members that retain the tennis net through grommet holes in the net. The net-retention members extend downwardly from the upper end of the middle portion to define an arcuate net-support surface. A lower portion of the unitary body includes two off-set, J-shaped ground-retention members, opposite the net-retention members. The ground-retention members have a ground-retention surface that forms an anchor post insertion channel. The insertion channel enables insertion of an anchor post recessed beneath the court surface. The ground-retention members have free ground ends that enable maneuvering of the anchor post within the anchor post insertion channel.

A portable boundary system (PBS), which is a complete pre-measured boundary-line system used for sport specific boundary lines/markings. Whether tennis, pickleball, basketball, badminton or other sports requiring boundary lines/markings, the PBS's of the present disclosure allow a single user to accurately set-up and define a sport's court/playing area. Assembly and disassembly of PBS's and pop-up nets takes a fraction of the overall time and cost of traditional court assembly methods. Since PBS's and pop-up nets are portable, they can be packaged efficiently and moved to varying locations. PBS's do not mark or mar gym floors, concrete, asphalt, grass or other hard or soft surfaces. PBS's are made from PVC/Vinyl and are durable and re-usable.

The invention relates to a kit of parts (100) for building a support base (1) for a pole-like element (2), wherein the kit of parts (100) comprises at least three substantially L-shaped elements (3), each L-shaped element (3) being arranged with an upright part (3A) extending along a body portion (101) of the pole-like element (2) in a direction parallel to a longitudinal axis (z) of the pole-like element (2) and with a foot part (3C) extending outwardly from a lowermost portion (102) of the pole-like element (2), wherein the kit of parts (100) further comprises a first holding means for holding a substantially right-angled part (3B) of each L-shaped element (3) in proximity of the lowermost portion (102) of the pole-like element (2).

A multifunctional detachable ball net frame includes a center rod, a plurality of side rods, and a plurality of net surfaces. A plurality of clamping grooves is concavely defined on an outer side surface of the center rod. The plurality of the clamping grooves vertically extends. The plurality of the side rods is disposed on a periphery of the center rod and vertically extends. A first end of each of the plurality of the net surfaces is respectively and fixedly connected to one of the plurality of the side rods. A first fixing column is disposed at a second end of each of the plurality of the net surfaces. The first fixing column is detachably inserted into one of the plurality of the clamping grooves. The multifunctional detachable ball net frame is easy to replace into a three-person set or a two-person set according to actual needs.

A net system used for example a sports game and a fine height adjustment system is provided. A cable mount is coupled to one or both of the upright posts with coarse height adjustment. A cable system for supporting the net includes a first end coupled to the upright post, and a second end coupled to a tension system of the other upright post. An intermediate portion of the cable system is slidably coupled along a pivoting member of the cable mount. The cable mount includes the fine height adjustment system that is coupled to the pivoting member. The pivoting member is pivotable in an upward direction or a downward direction upon movement of the fine height adjustment system without relieving tension from the cable system. The total distance of travel provided by fine height adjustment may be less than an incremental distance with coarse height adjustment.
