Stretching device

Abstract

This article is an air-injection type neck stretching device. The tip of the part that appears in a tubular shape on the right side of the perspective view is the pump part. By operating this pump part, it is possible to adjust the amount of air in the pleat part shown in the center on the right side of the right side view. Since the gradient to the neck muscles can be adjusted by the amount of air in the pleat part, it has a structure that easily fits the user's neck muscles. Also, as shown in the front view, rear view, and plan view, etc., it has a shape with protrusions of different sizes at the parts that support the neck and head of the main body.
