Abstract
With conventional cloth hammocks, when a person lies thereon and the fabric is pulled taut in the cloth-length direction, suitable elasticity cannot be achieved, leading to poor comfortability. According to the present invention, a forced crimping unit () forcibly produces crimping (wrinkles) to create suitable elasticity so that an impact on a human body by way of the movement is eased; and a design of adjusting level differences () thus produced to meet with the contours of the human body reduces variation in the weight distribution on the human body, thereby improving the comfortability. Moreover, a hooked clip (), which is a component of the forced crimping unit (), moves flexibly in response to the loading, thereby preventing damage to the cloth of the hammock and improving durability.
