AI Technical Summary
Technical Problem
Existing armrests on chairs, particularly bathroom chairs for individuals with disabilities, are fixed, restricting users when standing up and increasing packaging size due to their inability to fold, leading to high transportation costs.
Method used
A chair armrest structure with a pivotable design using a pivot hole, elastic members, and a position regulating groove allows the armrests to fold and store, reducing volume and enabling stable support during use.
Benefits of technology
The armrests can be folded for reduced packaging size and transportation costs while providing stable support and expanding the range of use by allowing sideways movement when standing up.

Abstract
This chair provides an armrest structure that allows the armrests to be folded and stored, and also reduces the overall packaging size. [Solution] The chair armrest structure includes an armrest structure 2 provided on the chair 1, and comprises an assembly base 21, an armrest 22, and a connecting member 24. The assembly base is coupled to the chair and has a hollow chamber 211, and is provided with a pivot hole 212, a pivot fixing hole 213, and a displacement groove hole 214 communicating with the hollow chamber. The armrest has a pivot hole 221 corresponding to the pivot hole of the assembly base, and the armrest is pivotally attached to the assembly base by inserting a pivot 23 into the pivot hole, and a position regulating groove 222 is formed on the periphery of the armrest. The connecting member is arranged corresponding to the hollow chamber of the assembly base. A first hole 241 corresponding to the pivot fixing hole and a second hole 242 corresponding to the displacement groove hole are formed on the connecting member.
