1. Field of the Invention
The present invention relates to a foot stand and particularly to a foot stand located on a lower end of a supporting rack which holds a concert article in a liftable manner.
2. Brief Discussion of the Related Art
A conventional foot stand, referring to R.O.C. patent publication No. 375346 for an example to hold a microphone, mainly aims to hold a post with the top end latching on a holding rack to hold the microphone at a front end thereof. Its features include an anchor post, a fastening dock, an anchor seat, an adjustable rack and a fastening element. The fastening dock has a through hole on one end and a screw hole on one side of the one end normal to the through hole. The anchor seat has another through hole on one end corresponding to the through hole of the fastening dock. For assembly the upper side of the anchor post is fastened to the fastening dock and another end of the anchor seat that does not have the another through hole. The adjustable rack runs through the through holes of the fastening dock and the anchor seat and is movable to a desired location, then a fastening element can be fastened in the screw hole to brake and anchor the adjustable rack. It has a tripod base which needs a greater supporting area. When in use the tripod is frequently kicked by people incidentally. To remedy this problem one of approaches is to adopt a foot stand consisting of a flat bottom surface at a smaller supporting range. While such an approach improves the kicking problem of the conventional tripod foot stand, it creates another problem by forming an unstable gravity center. For instance, in a concert the supporting rack with the foot stand at the lower end usually aims to hold a liftable concert article, such as a microphone, music score or musical instrument. Those articles are frequently touched by performers during the concert. A shrunk foot stand on the lower end of the supporting rack tends to skew the gravity center from the vertical line while holding the concert article. Hence the supporting rack is easily tilted and toppled. The costly microphone or musical instrument held on the supporting rack could drop to the floor and be damaged. A great loss could occur. Hence how to provide an improved foot stand to allow the supporting rack to return by itself after the gravity center is skewed from the vertical line is an issue pending to be resolved in the industry.
Therefore the primary object of the present invention is to solve the aforesaid problem. The invention provides a foot stand that can prevent a supporting rack from toppling when subject to an external force and tilted slightly. It also enables the post of the supporting rack to return to a vertical condition after tilted.
The foot stand according to the invention is located on a lower end of a supporting rack which holds a liftable concert article. The concert article may be a microphone, music score, or musical instrument. The foot stand includes a base which has an arched portion and a bottom, a balance weight located within the bottom with the weight decreasing gradually from a lower side to an upper side and a center screw hole on an upper side, and a post to hold the liftable concert article that has a threaded portion fastenable with the center screw hole. With the aid of the balance weight, the foot stand does not topple when it is slightly tilted under an external force, and can return to the vertical condition after tilted.
