Improved pickleball net apparatuses are provided. An example pickleball net apparatus comprises a pair of end posts each configured to be affixed to a pickleball court or to a respective base and to have a net stretched between the end posts. Each end post comprises a flexibility component that is positioned above a location of the affixing, and provides for the end post to bend at the location when a pressure is applied. Example net conversion apparatuses that are adaptively configurable to convert a net for use from tennis to pickleball or vice versa are also described.

A base stand for multi-player pickleball has a central post and three elongated members extending from the post substantially perpendicular to post. The elongated members are oriented about 120 degrees apart. Three legs extending from a distal end of the post to support the base stand on a playing surface. Nets are connected to the elongated members positioned about 120 degrees apart to form a circular pickleball court.

Ball collecting and returning installation for a court surface includes a back wall having a ball inlet opening and a ball outlet opening, a damping net spaced apart from and in front of the back wall and which has an opening at least partly aligning with the ball outlet opening, and a trough below the damping net and extending from the back wall to a location in front of the damping net. The trough guides balls landing therein to the ball inlet opening through which the balls pass into a ball collection receptacle behind the back wall. A ball propulsion device is also behind the back wall, elevated on a platform above the ball collection receptacle, and receives balls from the ball collection receptacle and propels them through the ball outlet opening onto the sports court surface.

The utility model discloses a volleyball sign post which comprises a post body, a sliding sleeve, a sliding clamping piece and a jacking mechanism, the jacking mechanism is fixedly arranged on the post body, the sliding sleeve is arranged above the jacking mechanism in a sliding mode, and a first clamping groove matched with the upper edge of a ball net is formed in the sliding sleeve. A sliding clamping piece matched with the upper edge of the ball net is arranged in the first clamping groove in an up-down sliding mode, the lower end of the sliding sleeve is in threaded fit with a jacking mechanism, and the top end of the jacking mechanism is matched with the sliding clamping piece. And a grip is fixedly arranged at the bottom end of the rod body. A movable rod is arranged at the bottom end of the grip, a sliding bowl is arranged at the bottom end of the movable rod, a second clamping groove matched with the lower edge of the net is formed in the sliding bowl, and a pressing mechanism matched with the lower edge of the net is arranged in the second clamping groove. The volleyball sign post is simple in structure, ingenious in design, convenient to disassemble and assemble and practical in function, and effectively solves the problems that in the prior art, a sign post is usually a simple vertical rod, a fixing structure is lacked, and installation efficiency is affected.

The present invention provides a multifunctional tennis net barrier, which relates to the technical field of tennis nets. It includes a main body bracket. The main body bracket includes a pair of supporting bottom rods. A ball net support rod is slidably installed in the supporting bottom rods. Transverse sliding grooves are provided on both the upper and lower halves of the ball net support rod. A sliding mechanism is rotatably installed in the sliding grooves. The sliding mechanism includes a movable rod. A sliding groove is provided in the movable rod. A moving slider is slidably installed in the sliding groove of the movable rod. Springs are fixedly installed between the two sides of the moving slider and the movable rod respectively. A short cylindrical rod is fixedly installed on the moving slider. The short cylindrical rod on the moving slider is slidably matched with the sliding groove on the ball net support rod. The ball net of the present invention can horizontally slide in the downwind direction when the wind blows outdoors, making it easier for the players in the downwind direction to hit the ball over the net and ensuring the fairness of the activity. The nylon net of the present invention can wrap and store other ball tools together during storage, facilitating the quick access of tennis tools.

The utility model discloses a portable badminton post which comprises a stand column, a plurality of containing grooves are formed in the outer side of the stand column, supporting rods are rotationally connected into the containing grooves, threaded rods are rotationally connected into the supporting rods, clamping rods are arranged on the outer sides of the threaded rods in a sleeved mode, clamping grooves are formed in the containing grooves, and the clamping rods are connected with the clamping grooves in a sleeved mode. The sides, close to the stand columns, of the multiple clamping rods extend into the corresponding clamping grooves, connecting rods are fixedly installed at the top ends of the stand columns, limiting bases are fixedly installed at the top ends of the connecting rods, sleeves are arranged on the outer sides of the limiting bases in a sleeving mode, two sliding blocks are slidably connected into the limiting bases, and springs are fixedly installed between the two sliding blocks. Pin rods are fixedly mounted on the sides, away from each other, of the two sliding blocks. According to the portable badminton post, the badminton post can be quickly folded and stored, the overall size is reduced, the carrying convenience is further improved, meanwhile, the multiple supporting rods can be used for supporting, the stability is high, and the portable badminton post can meet the use requirements of different scenes.

In a flat roll-up structure for rolling up net body flatly, at upper and lower end of net body, it is installed respectively with protruding object, meanwhile, at roll-up mechanism, it is installed with upper and lower positioning roller module to limit the movement scope of net body, therefore, when net body is to be expanded, net body, through the guidance of upper and lower positioning roller structure, can be withdrawn flatly; when protruding object used to roll up net body is limited for its movement scope by upper and lower positioning roller module, and is limited by the limiting part of upper and lower positioning roller module, the net body can then be rolled up flatly without generating up and down shift, which can avoid the generation of tying problem due to unbalanced receiving in net body.
