Description

  The present invention belongs to a kind of technical field of footrests, and particularly refers to the application of improvement of leg structure of combination flats such as net hanging.

  Ball games that generally require a net are badminton, tennis, splash, volleyball, etc. Many of the nets are stretched by pillars fixed to the ground. For this reason, the general public must go to school or a specific place whenever he wants to play. However, in view of the growing athletic population and urban stadium tribes, people are always playing on the easy net and always feel the inconvenience that the net brings. For this reason, we have devised a kind of assembly-type net that is convenient to carry and assemble.

  Please refer to FIG. The net device disclosed in Patent Document 1 is mainly composed of two counter tubes 92, two couplings 93, a main frame 94, a foot tube 95, a flexible net 96, and a net body 97. Although the flexible rope 96 is stretched between the above-mentioned parts to facilitate the attachment / detachment of the net, the conventional devices have the defects described in the attachment / use. First, the foot tube 95 is combined with the entire connection 93, and there is no fixing structure between the foot tube 96 and the connection 93, so the foot tube 95 is easily detached from the connection 93. Next, the main frame 94 is composed of an upright pipe 941, a horizontal pipe 942, and a horizontal pipe 943 that passes the horizontal pipe 942, and the main frame 94 is connected to the connection 93, but the overall structure is deformed due to the poor design structure. It's easy to do. In response to the above-mentioned defects, another idea was born.

  Please refer to FIG. It is a device of Patent Document 2 “Improvement of the net combination structure”. Since this device is an improvement of the above-mentioned American search, the main parts are the same, two rolling connections, two vertical tubes, It consists of four sideways pipes, two flexible ropes, bottom pipes and various connectors, nets, flexible keys and binders, etc., and the main improvement features are as follows. Protruding from each end and penetrating through four holes, the two longitudinal tubes are made into an appropriate length air core tube and connected at the upper end of the connection. The four transverse tubes are also air tube of appropriate length, penetrating the two transverse tubes and the left and right sides of the exhibition connection. The flexibility of the two flexible ropes is fixed to one end of the transverse tube and penetrates the left and right of the other connection through which the connection penetrates. One end of the bottom pipe penetrates the rolling connection, and the other end is connected to the connecting pipe. The net is pulled into the pipe by two fabric films on the left and right, and positions corresponding to each other on the net are provided. The flexible key is also flexible and has a rolling connection from the vertical pipe at one end. It has parts that contrast with each other in each connecting pipe connected to the bottom pipe, and there are two vertical pipes and two rolling pipes without the vertical pipe. The connection, the two bottom tubes and each connecting tube are integrated with each other by the restraining force of the flexible key. The two ends of the flexible key are stopped at the end, and the end stop is slightly larger than the inner diameter of the vertical tube and is fixed on the side of the net. The binder extends to the bottom pipe, stabilizes the bottom pipe, and the binder has a plurality of large and small notches. '' This allows the flexible rope to extend to the inside of the horizontal pipe and the rolling connection, and the horizontal pipe is controlled by the flexible rope. Connected to the left and right, the flexible key extends to the vertical tube. The rolling connection, bottom pipe, and related connecting pipes are integrated with each other by the restraining force of the flexible key. When the net is aligned with the vertical pipe, the end of the flexible key is put into a groove, and the entire structure of the net is constructed. To stabilize.

  Although the above described combined structure can improve the structural defects of the US patent, there are defects in use, which will be described later. First, the “stool” on the two sides is composed of a “lateral tube” in a set with a “connecting portion”. Not only does the user have to pull out and assemble during removal and assembly, it takes time and effort. At the same time, the structure and binder positioning are inconvenient. In addition, the "flexible rope" of this device is made up of parts such as "rolling connection, vertical pipe, horizontal pipe and bottom pipe", which is inconvenient in construction and requires force when removing and configuring the vertical pipe at the same time. It is time consuming and inconvenient, and there is a need to improve this.

  In light of this, the inventor has conducted extensive research on the problems faced by the above-mentioned ideas based on his long experience in related businesses, actively searching for solutions to tactical needs, Through efforts, research, and trial manufacture, we finally succeeded in the present invention “Leg Folding Improvement Application Net Device” and led to the improvement of the above-mentioned defects.
