Patent number: 11639733Abstract: A dual rod positioning structure, for connecting and fixing two single rods sleeved on or inserted into one another, includes positioning holes respectively located on rod bodies of the two single rods and a positioning seat capable of being engagedly fixed to the positioning holes and sleeved on the single rods. The positioning holes are arranged on two adjacent sidewalls of the single rods. Inserted into the positioning seat are a positioning element selectively engaged in the positioning holes, a spring, a positioning pin and an outward protruding button. The positioning structure overall is structurally simple, convenient to assemble, and stable in terms of positioning.Type: GrantFiled: April 3, 2019Date of Patent: May 2, 2023Assignee: CAMPVALLEY (XIAMEN) CO., LTD.Inventors: Kwang ho Baik, Renhua Chen

Patent number: 11523681Abstract: A table includes a table panel, first and second mounting members, and first and second leg assemblies. Each of the first and second mounting members is coupled or formed with the table panel. Each of the first and second leg assemblies includes a linking member having an end portion rotatably coupled with the first mounting member and another end portion rotatably coupled with the second mounting member. When the first or second leg assembly is unfolded, the linking member abuts one or more retainers of the table panel and forms interference fit with the first and second mounting members. This significantly reduces vibration when the table is in use.Type: GrantFiled: November 11, 2020Date of Patent: December 13, 2022Assignee: Inno-Sports Co., Ltd.Inventor: Renhua Chen

Patent number: 11499334Abstract: An improved pole frame structure of a foldable tent includes upright poles, side cross support rod assemblies, and a top support rod unit. The top support rod unit includes a top module provided with a limiting component, top support rod assemblies, and oblique support rods. One end of each oblique support rod is connected to the respective top support rod assembly by means of a slider provided with a stopper, and the other end of the oblique support rod is pivotally connected to the respective side cross support rod assembly. The structure enhances, by means of the stopper and the limiting component, the stability of the oblique support rods supporting tent cloth, and prevents the tent cloth from being damaged by the oblique support rods.Type: GrantFiled: April 3, 2019Date of Patent: November 15, 2022Assignee: Campvalley (Xiamen) Co., Ltd.Inventors: Kwang ho Baik, Renhua Chen

Patent number: 11382416Abstract: A foldable table includes a tabletop, first and second table leg assemblies, and first and second supporting assemblies. Each of the first and second table leg assemblies is pivotally coupled with the tabletop and rotatable with respect to the tabletop between a use position and a storage position. The first supporting assembly is pivotally coupled with the tabletop and first table leg assembly, and the second supporting assembly is pivotally coupled with the tabletop and second table leg assembly. Each of the first and second supporting assemblies includes first and second supporting members slidably and rotatably coupled with each other such that sliding and rotating movement between the first and second supporting members of a respective supporting assembly allows a corresponding table leg assembly to rotate with respect to the tabletop between the use and storage positions.Type: GrantFiled: November 18, 2020Date of Patent: July 12, 2022Assignee: Inno-Sports Co., Ltd.Inventors: Kwan Jun Choi, Renhua Chen

Patent number: 11330900Abstract: Disclosed are adjustable bars and structures having adjustable bars. An adjustable bar includes an inner bar, an outer bar and a locking/unlocking mechanism to control relative movement of the inner and outer bars. The locking/unlocking mechanism includes a locking pin to be selectively inserted into a restriction hole of the outer tubular bar and a restriction member of the inner bar, thereby selectively restricting relative movement of the inner and outer bars in at least one direction. The locking/unlocking mechanism also includes a feature to prevent accidental release of the locking pin from the restriction member. Structures having such adjustable bars are easy and safer to use.Type: GrantFiled: August 24, 2020Date of Patent: May 17, 2022Assignee: Inno-Sports Co., Ltd.Inventor: Renhua Chen

Patent number: 11291297Abstract: A picnic table includes a table panel, one or more bench panels and a supporting frame to support the table and bench panels. The supporting frame includes first and second supporting assemblies, each including a table support and one or more bench supports. The supporting frame further includes a table frame and one or more bench frames. The table frame rotatably connects the table support of each of the first and second supporting assemblies with the table panel. Each bench frame rotatably connects a bench support of each of the first and second supporting assemblies with a bench panel. The table support of each of the first and second supporting assemblies is adjustable in length. Adjusting the length of the table support changes the height of the table panel with respect to the one or more bench panels.Type: GrantFiled: September 30, 2020Date of Patent: April 5, 2022Assignee: Inno-Sports Co., Ltd.Inventor: Renhua Chen

Patent number: 11255104Abstract: A tent support includes a plurality upright rods, a top module provided at a center of a top of the tent support, a plurality of side rod assemblies each connected to every adjacent two of the upright rods, and a plurality of top rod assemblies connected to the side rod assemblies and the top module. At least one positioning hole is provided at a junction of two adjacent side walls of each upright rod. A sliding seat provided on each upright rod includes a positioning member which is selectively engaged in the positioning hole, a spring, a positioning pin and an outward protruding button therein. The tent support, as a whole, is simple in structure, easy to assemble, and stable in positioning.Type: GrantFiled: April 3, 2019Date of Patent: February 22, 2022Assignee: CAMPVALLEY (XIAMEN) CO., LTD.Inventors: Kwang ho Baik, Renhua Chen

Patent number: 11241087Abstract: Disclosed are adjustment mechanisms and structures including one or more adjustment mechanisms. An adjustment mechanism comprising a casing, first and second arms, a second arm, a button, and an elastic member. The first and second arms are movably disposed in a channel of the casing. The button is operably coupled with the first and second arms and selectively pushes a first end of the first arm out of a first side of the casing and a second end of a second arm out of a second side of the casing. The elastic member abuts the casing and button such that the button is held at a desired position and consequently the first and second arms are held at a desired state under normal conditions. The adjustment mechanisms of the present disclosure provide an easy, convenient and safe means for height or length adjustment.Type: GrantFiled: August 26, 2020Date of Patent: February 8, 2022Assignee: Inno-Sports Co., Ltd.Inventors: Kwan Jun Choi, Renhua Chen
