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 pickleball training net includes: a bracket and a rebound net, a cross member is arranged in a middle of the bracket, the cross member divides the bracket to form an upper half area and a lower half area, the rebound net is arranged in the upper half area of the bracket, the bracket is provided with a number of hooks to fix the rebound net, the rebound net is provided with a identification tape, a middle section of the rebound net is divided into a rebound area by the identification tape. The pickleball training net can assist the training person to complete single person training and the pickleball training net is easy to carry, the simulation is high, the rebound effect is good, the requirement on the field is low, and the inclination angle of the bracket can be adjusted according to the need.

A game playable on land or water is provided. The game may have a frame having a generally circular playing surface having a net and a plurality of legs attached to the frame. A plurality of buoys may be removably attached to the plurality of legs so that the game may float on water or the plurality of buoys may be removed from the legs so that the game may be played on land. A plurality of straps may connect the plurality of buoys to a centralized weighted anchor for balancing and stabilizing the game on water.

One example pickleball net apparatus includes first and second uprights, a scissor mechanism connected to the first and second uprights, a net removably connectible to the first and second uprights, and legs connected at least indirectly to the uprights, and the legs are configured to move automatically in response to manipulation of the scissor mechanism, so that the pickleball net apparatus moves between a folded state and a deployed state.

A let detection system includes a sensor including an accelerometer attached to a tennis net. The sensor is in wireless communication with an umpire device able to send a message to the sensor, wherein the message causes the sensor to calibrate and begin monitoring for a let. The sensor determines a three-dimensional (3D) vector representing the gravity acting on the sensor as a baseline. When the sensor detects vertical acceleration of the net relative to the baseline and the vertical motion is above a preset threshold, the sensor automatically transmits a let notification message to the umpire device.

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.

The present invention is a glow in the dark volleyball set with two illuminated volleyball poles, and an illuminated net stretched between the two volleyball poles. The glow in the dark volleyball set where the volleyball poles may be illuminated by LED lights or reflective material. The glow in the dark volleyball set with poles that may have integrated solar panels to sustain illumination. The glow in the dark volleyball set where the net is illuminated by LED lights or by reflective material.

A clamping device for holding an object in place comprising a female plate 10 with an exterior 11 and interior 12 surface and a bottom edge 15 with a plurality protrusions 16 wherein each of the protrusions has a opening 17 therein; a male plate 1 with an exterior 2 and interior 3 surface and a bottom edge 9 with a plurality of teeth 7; and at least two stepper keys 21 on said exterior 2 surface of the male plate 1; wherein the male teeth 7 fit snuggly within the female plate protrusion openings 17 such that the object placed between the male plate 1 and the female plate 10 is held in place by locking the stepper keys 21 in place.

Disclosed is system and method for measuring the tension of a tennis net, and, alternatively or in addition, for determining if a service let occurs via the measuring of the net tension. The disclosed embodiments measure a force exerted on the center-strap or the singles stick by the net. In these embodiments, the measured force provides an accurate reflection of the tension of the net.
