Floating vest and buoyant material thereof

Abstract

In a floating vest which can be provided with buoyant materials, the closed-fit feeling of a wearer is poor, and the buoyant material in the floating vest can sometimes delicately shift. A holding part for holding the buoyant materials is arranged between an external cloth and an internal cloth of the floating vest, at least one of the external cloth and the internal cloth is telescopic, each buoyant material is a lengthwise tabular body the cross section of which is rectangular or trapezoidal, more than three buoyant materials the cross sections of which are rectangular or trapezoidal or more than three buoyant materials the cross sections of which are trapezoidal are combined in parallel and held in the holding part. The crosswise width of the holding part of the floating vest is slightly smaller than the whole maximum width of the paralleled held buoyant materials, the bottom edge sides of the more than three buoyant materials are used as external cloth sides, the elasticity of the external cloth is overcome, and therefore the buoyant materials are forced to be held in the holding part, and the floating vest is curved.

Description

technical field [0001] The invention relates to a life-saving vest equipped with a buoyant material and the buoyant material used in the life-saving vest. Background technique [0002] In the life vest, the buoyancy material made of foam plastic or the like can be taken out or put into the storage part formed between the outer layer cloth and the inner layer cloth such as the left and right front body and the rear body supporting the back. For example, if Figure 8 , Patent Document 1 and Patent Document 2, a plurality of buoyant members having a rectangular cross-section are arranged to correspond to the curves of the body, and are stored between the outer fabric and the inner fabric. The buoyancy member having a rectangular cross-section is accommodated in each section formed by sewing the outer layer fabric and the inner layer fabric, thereby restricting its position. Alternatively, there is also a storage body in which each buoyancy material is placed in a divided bag-s...

Problems solved by technology

[0003] On the other hand, although this life vest is naturally curved and easy to wear when worn by fishermen, so that it fits close to the body from the back to the waist, in the structures disclosed in the above-mentioned patent document 1 and patent document 2, only Insert multiple buoyancy members with rectangular cross-section, each buoyancy member may move freely, even the shape of the life vest itself cannot be formed.
