Abstract

A diving aid is a bag body with a splayed opening, is used for being mounted at water stroking arms and legs of divers and can also be mounted at sleeves and trouser legs of diving suits so as to form diving suits with the diving aid. When a diver in a diving suit with the diving aid moves in water, resistance to the diving aid is small if the opening thereof faces rearwards, and resistance to the diving aid is higher if the opening thereof faces forwards because plates of the diving aid are expanded after being filled with water, and then the diver can utilize resistance generated when the diving aid opens to boost stroke actions of four limbs, thereby increasing diving speed greatly.

Description

A kind of diving supplementary instrument

[technical field]

The utility model relates to the diving apparatus, specifically a kind of diving supplementary instrument that can improve submerged speed.

[background technology]

Diving is leisure, the body building of a routine, the coordinated movement of various economic factors of scuba diver by four limbs and trunk float in the water and the arm stroke by four limbs at underwater exercise.Four limbs must guarantee that very the posture of striking of standard can form the power that advances when striking, must open the reaction force that increases water when striking backward, need close up the resistance that as far as possible reduces water etc. when stretching forward as palm.But,, on speed, all be difficult to be significantly improved no matter how four limbs move, how trunk is coordinated.

[utility model content]

The technical problems to be solved in the utility model provides the diving supplementary instrument that a kind of auxiliary scuba diver increases the resistance of striking, improves trip speed.

For solving the problems of the technologies described above, the utility model by the following technical solutions.

A kind of diving supplementary instrument is used to be installed in arm, the shank that the scuba diver strikes, and this assistor is the pocket with horn opening.

As the optimization to such scheme, described assistor is made up of two soft sheet materials, and two sheet materials periphery is local to be connected.

As the further optimization to such scheme, described two soft sheet materials are one for fixing to the substrate on the diving suit and be attached to on-chip lamellar body, and lamellar body is provided with gauffer.

As the further optimization to such scheme, described gauffer is arranged in the lamellar body both sides and is depressed in lamellar body, forms the conduit that is beneficial to the guiding current.

The relative prior art of the utility model has following advantage:

The diving supplementary instrument that the utility model discloses is when underwater exercise, little as the then suffered backward resistance of opening, then open forward as opening owing to the lamellar body water-filling, suffered resistance is big, thus, the scuba diver who wears the diving suit with diving supplementary instrument is when underwater exercise, and the resistance in the time of can utilizing diving supplementary instrument to open makes the arm stroke of four limbs stronger, can improve submerged speed greatly.

Accompanying drawing 1 is the utility model embodiment diving supplementary instrument perspective view;

Accompanying drawing 2 is a present embodiment diving supplementary instrument opening direction structural representation;

Accompanying drawing 3 is a present embodiment diving supplementary instrument rear structure schematic diagram;

Accompanying drawing 4 is applied on the arm for the present embodiment diving supplementary instrument and arm view when stretching forward;

View when accompanying drawing 5 is used on the arm for the present embodiment diving supplementary instrument and arm is struck backward;

Be further detailed below in conjunction with accompanying drawing.

[specific embodiment]

For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with specific embodiment and accompanying drawing.

Shown in accompanying drawing 1～3, the diving supplementary instrument that present embodiment discloses makes full use of four limbs when striking, and current have greatly increased the forward thrust when striking to the stressed effect of four limbs, have improved swimming rate.This diving supplementary instrument integral body is pocket, the one end is provided with flaring opening, when diving supplementary instrument during at underwater exercise, as opening forward, current can enter in the bag from opening, and diving supplementary instrument opens, it is big that the resistance of motion becomes, when the diving supplementary instrument opening backward the time then current can't enter in the bag, opening closes up, the resistance force diminishes of water.

This diving supplementary instrument is made up of two soft sheet materials, local connection of two sheet materials peripheries and form the pocket with horn opening thus.This two sheet material is one for fixing to the substrate on the diving suit 1 and be attached to lamellar body 2 on the substrate 1, and lamellar body 2 is provided with the gauffer 21 along opening direction, can combine by stickup, suture way between substrate 1 and the lamellar body 2, also can when injection mo(u)lding, form integrative-structure.Gauffer 21 launches after current enter in the diving supplementary instrument, guarantees that two sheet materials have enough big opening angle, increases the diving supplementary instrument water space capacity, further increases diving supplementary instrument resistance in water.Detailed force analysis such as Fig. 4, when diving supplementary instrument is installed on the arm and arm when stretching forward, current flow to the diving supplementary instrument opening direction from the diving supplementary instrument bottom, diving supplementary instrument closes up, and this moment, resistance was minimum, and when state shown in the accompanying drawing 5, be that arm is swung when striking backward, current enter the diving supplementary instrument from the assistor opening, and resistance increases greatly, form deboost thus trunk is moved forward.

Simultaneously, for reduce as far as possible four limbs in the process of moving forward water to the resistance of diving supplementary instrument, described gauffer is arranged in lamellar body 2 both sides and is depressed in lamellar body 2, is beneficial to the separately conduit of current, guiding current direction diving supplementary instrument two side flow with formation, reduces whole diving supplementary instrument resistance.Therefore, in order further to increase the shunting of gauffer, the effect of water conservancy diversion, the quantity of gauffer can be a plurality of.

Thus, this diving supplementary instrument can be fixed in positions such as the coat-sleeve, trouser legs of swimming suit, coat-sleeve forearm, trouser legs lower leg portion at diving suit are provided with many pieces of diving supplementary instruments, each assistor opening direction and arm, leg relative water (flow) direction when underwater exercise is coordinated, basic demand is: arm, current were as far as possible little to the resistance of assistor when leg travelled forward, and arm, current were big as far as possible to the resistance of assistor when leg was struck backward.

The material of the utility model diving supplementary instrument can adopt silica gel, PPE (polyphenylene oxide), PET (PET) and PVC durable soft materials such as (pvc materials), and the mode of can adopt stickup, making is stably fixed on the swimming suit.

The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
