Abstract
The utility model provides an umbrella-shaped web for open-close type water treading tools in water. The utility model is characterized in that the utility model which has an umbrella-shaped structure is tied on a shank of a person; the edge of the utility model is provided with a rope which is connected to a foot of the person. Compared with the diving web, the utility model has larger propulsive efficiency for treading water, and the utility model has the advantage that the activities on shores can not be influenced at the same time. The utility model can be used for swimming, diving, and life saving.
Description
The present invention relates to underwater exercise instrument, particularly web.
Web is the instrument of human diving and swimming, the mankind are trodden or underwater exercise more efficient.Web is that imitative fish tail is made.But,, more much lower than fish with the web propulsive efficiency of treading because people two foot is good at walking.Umbrella shape fin of the present invention is the open and close movement of imitative jellyfish, in conjunction with the characteristics of umbrella, produces novel underwater exercise instrument---Umbrella shape fin.
The purpose of this invention is to provide a kind of novel underwater exercise instrument, make the mankind more efficient, simultaneously, make not natatory people be easy to learn to swim or be convenient to self-lifesaving at underwater exercise.
The present invention is achieved in that Umbrella shape fin top fixed band is processed into and can allows foot pass and can tie up in shank top.After the umbrella cover top is so fixing, is subjected to the flow action umbrella cover or opens or close.Umbrella cover is subjected to supporter supports, setting.Supporter is connected to foot by tightrope in umbrella cover edge, or is through foot and goes up or be fixed on the footwear.When supporter intensity is enough big, can save tether.Like this, when water and umbrella cover are done relative motion, push away then that umbrella cover opens, obtain propulsive force or buoyancy; Draw then that umbrella closes, advance resistance is reduced, be beneficial to two foots alternately firmly, be convenient to advance or float.
Advantage of the present invention is: 1, improved the propulsive efficiency of treading.2, do not influence normal activity on the bank.
Accompanying drawing has been described one embodiment of the present of invention, accompanying drawing step under being the back Umbrella shape fin the state of opening and on draw the state that closes of back Umbrella shape fin.
Umbrella shape fin of the present invention is to make like this: fixed band 1 is sewed together by elastic webbing and umbrella cover top fold, and its elasticated is moderate, foot is easily passed and does not allow water see through.Umbrella cover 2 is cut out by the umbrella cover sample by waterproof chemical fabric and is made.Supporter 3 is made of plastics, and its two ends slyness is fixed together with umbrella cover, prevents to scratch lower limb.Tether 4 one ends are through foot, and an end disperses to lie in the marginal end of umbrella cover supporter.At last, the umbrella cover of Umbrella shape fin can the free folding with the effect of current.Under step on or pusher then umbrella open, anti-propulsive force is proportional to umbrella cover and opens area and fltting speed.Because after umbrella cover opened, umbrella cover was long-pending than the big manyfold of foot area, therefore, when treading, umbrella launches, and produces anti-propulsive force bigger when barefoot.When shank was mentioned, umbrella cover closed up automatically, can reduce resistance.
Claims (2)
1, the instrument Umbrella shape fin of treading in a kind of open-close type water mainly is made up of umbrella top fixed band, umbrella cover, supporter and tether, and it is characterized in that: fixed band is tied up in shank top; Umbrella cover is umbrella handle with the shank; Tether is linking outer end and the foot or the footwear of umbrella cover upper support.
2, Umbrella shape fin as claimed in claim 1 is characterized in that Umbrella shape fin in the presence of hydraulic pressure, does not allow water see through umbrella cover.
