Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a method for installing a basket stand and an installation guide device.

Conventional technology A mobile basketball stand used for basketball games has a forward-bent arm erected on a movable support stand with rollers that roll on the floor of a gymnasium, etc. A goal net is suspended from a board suspended in the center of the board via a ring, and most are constructed so that the arms can be folded into a compact size. This movable basketball stand must have a structure in which the support stand does not easily cause the arm to fall, and the basketball must not be shocked by the basketball hitting the board, or a player may touch the ring during a basketball game. In order to prevent the basket stand as a whole from tipping forward even if the ring is pushed downward due to a collision, the support stand has balance weights, etc., and is quite heavy, as well as having a sturdy structure. The moving work is also quite troublesome and troublesome.

Furthermore, after moving this movable basket stand,
The outriggers provided on the support base are brought into contact with a floor surface or the like to securely fix the support base.

Problems to be Solved by the Invention It goes without saying that when the above-mentioned basketball stand is used for competitions, the goal net must be placed at an accurate predetermined position on the basketball court, but in the case of the above-mentioned mobile basketball stand, After moving the basketball stand to a predetermined position, hang a weight string from the goal net to determine its position on the basketball court, measure it, and if it is not in the correct position, move the basketball stand further and correct it. This required complicated and time-consuming work. Therefore, we put stickers etc. in designated positions on the basketball court.
Mark the corresponding basket stand and visually align the marks to determine the approximate position, or bury floor metal fittings at a predetermined position in the basketball court and connect this metal fitting to the basket stand. Positioning has been carried out by connecting the two. However, since the basket stand is quite heavy, even in these cases, it is still necessary to move the basket stand back and forth and left and right many times to make fine adjustments, which is still complicated.

This invention was made in view of the above circumstances, with the aim of solving the problem that it is complicated and time consuming to set the correct arrangement because the basket stand cannot be easily moved as described above.

Means for Solving the Problems In order to solve the above problems, metal fittings are embedded and fixed in advance at at least two points at the location where the basket stand is installed near the goal of the basketball court, and the wheels for moving the basket stand are attached to the metal fittings. A frame body forming a movement guide part is removably connected, and the moving wheels are guided to the movement guide part to cause the basket stand to ride on the frame body, and then the basket stand and the frame body are connected. In addition to configuring the characteristic method of installing a basket stand, frames constituting a triangle and a square are integrally formed with one side of the square frame as the base, and a concave frame is integrally connected to the bottom of the square frame to form a square. A guide portion into which rollers for moving the basket stand enter is formed on both sides of the frame, a cylindrical body is integrally connected to the corner portion of the concave frame and the apex portion of the triangular frame, and a conical shape is formed on the cylindrical body. A shaft hole is formed that is continuous with the hole, and a conical protrusion is formed at the end of the shaft hole, and the cylindrical body is aligned with a floor metal fitting buried near the goal of the basketball court and serves as an outrigger on the basket stand. We have constructed a basket stand installation guide device into which a screw shaft can be inserted.
