Title: Checking device using the center of gravity of the golf ball
IPC: A63B57/00
Filed: 2020-06-09
Granted: 2021-11-24
Abstract: The present invention relates to a device which confirms and displays the center of gravity of a golf ball, and more specifically, to a device for displaying the center of gravity of a golf ball, comprising: a body part filled with an aqueous solution that floats a golf ball therein; a cover part through which a golf ball is introduced and moves, wherein when the golf ball stops moving, a cover is closed and the golf ball is fixed; and a display part attached to an upper portion of the cover part. Displaying is performed at the center of an upper portion of a golf ball fixed by a golf ball upper fixing member of the cover part and a golf ball fixing step of the body part. Accordingly, the device for displaying the center of gravity of a golf ball is characterized in that when the body part is filled with the aqueous solution, a golf ball is introduced into the body part, and the center of gravity is found, the cover part is closed to fix the golf ball in the body part so that the golf ball does not move and displaying is performed by means of a display means. Accordingly, the device is advantageous of: being easily usable; reducing the amount of the aqueous solution used since the size of a space filled with the aqueous solution, such as a lower space, is minimized; being conveniently usable since the configuration constituting the device is simple; produced at low costs; and being easily carried.

Abstract: The present invention relates to an entrance for fish trap, capable of preventing the escape of an octopus, and a fish trap using the same, and specifically, to a novel concept of technology capable of preventing an octopus captured in a fish trap from escaping to the outside and facilitating entry of an octopus, thereby increasing a catch of octopuses and remarkably increasing incomes of fishermen. A conventional entrance for a fish trap has a rectangular cross section of net ribs constituting a net body and accordingly, when the flow velocity acts from an inlet to an outlet, the outlet is widened while receiving a lot of resistance, and thus, an octopus caught in the fish trap escapes to the outside, thereby causing a reduction in a catch of octopuses. In order to solve the above-mentioned problem, in the present invention, a technology in which net ribs constituting a net body of an entrance for a fish trap formed by an assembly configuration of a pair of upper and lower entrances split in half are formed to have a circular cross section to reduce resistance caused due to a flow rate and prevent the opening of an outlet is devised.
