Abstract

The utility model discloses a floating belt for swimming exercise and belongs to an auxiliary floating apparatus for swimming exercise. The floating belt is the floating apparatus with a flat oval shaped wide belt sectional surface. The two ends of the floating belt is provided with structures connected with each other. When the floating belt is used, the floating belt is tied on the body of a swimmer to be wrapped into a circular shape. The elastic degree and position of the floating belt on the body can be adjusted. Compared with a life saving ring, the floating belt has the advantages of simple manufacture, small swimming resisting force and balanced and medium floating force. The floating belt can help a swimming beginner master the correct swimming posture and action fast. The floating belt is especially suitable for the swimming exercise of adolescents and children.

Description

Floating belt for swimming exercise

The utility model belongs to the auxiliary buoying device that a kind of swimming instruction is used, and it is that the cross section of the structure of interconnecting is arranged is the broadband shape buoying device of flat ellipse substantially at two ends.

The utility model and existing buoy quoit, particularly semi-ring type buoy quoit is similar on external form, and all there is the structure that interconnects of adjustable-length at two ends.But buoy quoit is mainly used in waterborne helping out of distress, thereby from security standpoint, requires buoyancy big, so cross section, inflation back is rounded, and when the swimming instruction, the buoying device resistance that moves about in this circular section is big, not next to the shin, easily string is moving, and it is too high that swimmer's head and shoulder are surfaced, and is unfavorable for grasping correct swimming posture and action, in addition, make buoy quoit mold complexity, cost is higher.

The purpose of this utility model is that a kind of buoyancy of design is moderate, makes simple and easyly, and the resistance that moves about is little, ties up to the buoying device that is suitable for swimming instruction that the swimmer is more convenient for adjusting position and degree of tightness on one's body.

Shape of the present utility model is that the cross section is the broadband shape buoying device of flat ellipse substantially, tying up to the swimmer circularizes on one's body, the floating band in flat ellipse cross section and the contact surface of health are big, it is moving to be difficult for string, also reduced the resistance that moves about, the structure that interconnects of adjustable-length is all arranged on the floating band end angle, two ends, can adapt to different builds and different exercise item purpose needs within the specific limits.The floating band portion thickness that is positioned at swimmer's health side is attenuate relatively, makes it be easy to bending on the side, and fixing running condition in swimming is difficult for having guaranteed the equalization stable of buoyancy along the health moving.

The utility model can form with the plastic film heat seal, and mould is simple, and is with low cost; Also available mackintosh manufacturing, then abrasion test can greatly strengthen, and these two kinds of materials can be made the floating band of inflatable, can also manufacture the floating band of lightweight formula with the hermetic type foamed plastic, no gas leakage problem, safety is more secure.

The utility model is applicable to the swimming beginner of all ages and classes, various builds, especially is fit to children's swimming instruction and uses, so several specifications should be arranged, long by 60～120(cm), wide by 20～40(cm), long and wide ratio can be 3:1 or 4:1.

Accompanying drawing has been described an embodiment of the present utility model:

Fig. 1 is the floating band of inflatable swimming instruction front elevation.

Fig. 2 is floating band birds-eye view.

Fig. 3 is floating band cross section, A-A.

Fig. 4 chews explosion views for unidirectional insurance gas.

On two end angles at figure come-up band two ends when use interconnective rope pore structure (1) is arranged, become three independently air chambers along floating band longitudinal subdivision, be blown into half gas during use, it is enclosed tie up to setting on one's body, floating band cross section is squeezed into flat ellipse naturally, unidirectional insurance gas all is housed on each air chamber chews (2).

An end osed top tubular structure was arranged at the bottom in unidirectional insurance gas was chewed, and the duct occlusion end has the semi-circular cut-out (3) that cuts, and air-flow backs down otch and enters air chamber during inflation, and otch is closed on air chamber internal gas pressure top when not inflating, and has played the security insurance effect.

Claims

1, exercise swimming, particularly annular mostly, cross section, inflation back be circular, encircle the auxiliary buoying device that there is the structure of interconnecting at two ends, feature of the present utility model is:

A, described floating band are the broadband shape when launching, and interconnect structure (1) on two end angles at floating band two ends.

B, the cross section was flat ellipse substantially when this floating band used.

2, floating band according to claim 1 is characterized in that floating band both sides, and being positioned at the person side part during use has the thin zone of purpose made for ease of bending.

3, according to claim 1, the floating band of 2 described inflatables, it is characterized in that being divided into several separate and be equipped with the air chamber that unidirectional insurance gas is chewed.
