Shower chair armrest assembly structure

Abstract

This invention relates to a shower chair armrest assembly structure, comprising a chair frame, a backrest, two armrests, and two fastening devices. The chair frame has a front rod and a rear rod, with the rear rod having an insertion hole. The armrests have an upper support section above them, with a front connecting section extending downwards from the front and a rear connecting section extending downwards from the rear. The rear connecting section has a insertion section below it that can pass through the insertion hole. The fastening devices include a fastening block, a fastening button, and an elastic element. The fastening block is fixed to the front rod and has a fastening portion. The fastening button is located on the front connecting section of the armrest and has a control section and a hook section linked to the control section, the hook section having a hook body. The elastic element provides actuation elasticity to the fastening button, and the elastic force of the elastic element allows the hook body to engage with the fastening portion; pressing the control section disengages the hook body from the fastening portion. This design allows for better handrail opening and closing convenience and stability.
