The invention relates to an environmentally-friendly street light with a multi-stage gear drive to generate electricity by using the public seat gravity potential energy which includes a base plate, a plurality of lifting seats surrounding the circumference of the base plate, a light pole and a light disposed on the base plate, power generating devices respectively corresponding to the lifting seats, and a storage battery. The bottom of the lifting seat is provided with a rebound device for raising the lift seat, and a one-way driving strip is disposed on the rear side of the lift seat. The power generating device includes a first power generating device and a second power generating device. The first power generating device includes a first shifting gear set that transmits to connect to the one-way driving strip, and a first power generator. The street light has a reasonable structure, and can utilize and store the electric energy converted by the gravity potential energy generated when the human body sits down. It saves energy and reduces pollution, and is beneficial to environmental protection.

The purpose of this device is to give assistance to a person that is standing in a particular area for an extended amount of time. This is achieved for people of different heights by having a rotating joint at the base. A saddle joint at the base of the housing enables this device to be adjustable. The seat portion can rotate to adjust to different people. This supporting system is designed to bear some of the load while standing, to accommodate a more ergonomic environment for the person standing.

The present invention aims to adjust the height of a musical instrument chair, including an upright rod seat, a pressing plate, a return spring, and an upright rod, wherein the upright rod seat comprises an up-to-down through receiving space and a side opening horizontally communicated with the receiving space; the pressing plate is disposed at the side opening and pivoted to the upright rod seat; the return spring is disposed between the pressing plate and the upright rod seat; and the musical instrument chair is disposed at an upper end of the upright rod, and the upright rod penetrates into the receiving space from up to down, and is provided with a plurality of height-different fastening slots in which the pressing plate is fastened at the normal position so as to fix the upright rod.

A seating furniture chassis having a height-adjustable seat surface, a drive means, a shaft, a height-adjustment mechanism and a threaded rod, wherein the drive means is coupled to the shaft and is designed to transmit a torque to the threaded rod by means of the shaft, and wherein the height-adjustment mechanism is coupled to the threaded rod and to the seat surface such that a rotation of the threaded rod is converted into a height adjustment of the seat surface by means of the height-adjustment mechanism, characterized in that a longitudinal axis of the shaft is not arranged parallel to a longitudinal axis of the threaded rod.

A stool comprises a height-adjustable seat. The seat is coupled to a stem of the stool using a ball and socket mechanism. The ball and socket mechanism enables the seat to be tiltable up to 20 degrees in all directions about a vertical axis. The ball and socket mechanism aids in providing the seated individual with an increased range of motion. The range of tiltable motion can be adjusted using an adjustment member.
