Claims

[Scope of utility model registration request]

In a jump umbrella that has a lower shaft that is telescopically fitted inside the upper shaft via a coil spring and has a handle at the lower end, the shaft is biased in the direction of protrusion from the small hole in the upper and lower shafts when the shaft is fully extended. a protrusion provided in the lower shaft, and an upper repellent whose lower end is fixed within the lower shaft when the shaft is in an extended state, and whose upper locking claw can lock into the engagement hole of the upper and lower shafts; It consists of a lower reel whose upper end is fixed below the upper reel and a locking claw and an operation button protrude from an opening near the handle of the lower shaft. Approximately parallel taper parts are formed on the upper surface of the locking claw of the repellent and at the corner of the base of the operation button of the lower repellent, and hook-shaped parts at both ends of the dogleg-shaped spring straddle these two taper parts. An expansion and contraction mechanism for the shaft of a jump umbrella, characterized in that the shaft is engaged.
