Foldable pocket umbrella
Abstract:
A foldable pocket umbrella is proposed that includes a handle cover and a support element of a truncated cone-shaped tripod element having air ducts for ventilation of the interior of a handle cover. The support and a three point bearing achieves optimal conditions conferring minimal frictional losses between support element and inner wall of the handle cover and resilient stability to the umbrella.
