Description

Boosting swimming aid

The utility model relates to a kind of swimming tool.

At present, mostly the swimming tool of market supply is water wing or life vest form.Can not stop during free-hand swimming, thereby can not get having a rest, relatively more dangerous; Dress life vest or water wing, though can obtain having a rest, compare safety, very too fat to move, resistance is big, is difficult to action in water.The inventor (applicant) has proposed a kind of novel swimming tool in application number is 92220946.4 patent application, but still has complex structure, uses and carry not very convenient weakness.

At the problems referred to above, task of the present utility model provides a kind of new-type assisted swimming tool.

The utility model is to realize like this, it partly is made up of buoyancy aid, bearing block, crank, axle, pedal, lashing etc., tail end at buoyancy aid is connected with bearing block, axle is contained in the bearing block, crank becomes just to connect with axle, crank two rotating shafts are at a distance of 180 ° and at grade, crank and axle all can rotate flexibly around bearing block; Two pedals become hinged with crank two rotating shafts, and can distinguish flexibly and rotate; Front end at buoyancy aid is fixed with lashing, can be used for and the connecting of human body.

Another program of the present utility model is that the front end of buoyancy aid is a sheet, tail end is that one or several etc. are worn face column symmetric arrays, and is formed along peripheral sealed attachment by airtight film, charges and discharge the gas valve on it, charge into the gas postforming, also can make less than the material of water by density.

Another scheme of the present utility model is that the number of the bearing block of this assisted swimming tool and axle is the same with the number of buoyancy aid tail end uiform section column body; Bearing block becomes movable and connects with the buoyancy aid tail end, and can only move forward and backward at uiform section column body upper edge axis direction.The position can be decided according to instructions for use, locatees during use.

A scheme more of the present utility model is that buoyancy aid can be overlapping by two identical parts, and is connected into one in corresponding place.

The utlity model has safe, in light weight, volume is little, carries with easy to use, and is simple in structure, low cost and other advantages.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is an another structural representation of the present utility model.

As shown in Figure 1 and Figure 2, the 1-buoyancy aid, the 2-bearing block, the 3-crank, the 4-axle, 5,5 '-pedal, the 6-lashing, 7,7 '-crankshaft.

Before the use, buoyancy aid 1 unaerated, bearing block 2 can move freely at buoyancy aid 1 tail end, regulates particular location according to user's leg length; With gassy in the buoyancy aid 1, whole buoyancy aid is heaved as Fig. 1 or shape shown in Figure 2 during use, and makes the bearing block location; For the swimming tool of structure shown in Figure 1, buoyancy aid front end and trunk front portion or rear portion are close to, for the swimming tool of structure shown in Figure 2, then two of buoyancy aid front ends are close to the trunk front and rear part respectively; Form firm the connection with lashing 6 and human body then; Human body is flat to be faced upward or flat crouching on the water surface; Under buoyancy, whole human body is bubbled through the water column and is guaranteed that the human body center line is parallel with the water surface, and axle 4 is near the horizontal plane; At this moment people's both feet place on the pedal and fix, and scrunch in turn two pedals 5,5 ', make pedal 5,5 ' around crankshaft 7,7 ' rotation, crank 3 and axle 4 are that buoyancy aid 1 rotates around bearing block 2 simultaneously, two pedals 5,5 ' can constantly take turns to strike backward or forward, under the reaction force acts of water, promote the people and move forwards or backwards.Simultaneously, people's both hands are freely, and available any posture helps swimming and turns to.

The utility model has adopted the pedal mode of striking to advance, so propulsive efficiency is higher, swimming not only fast but also laborsaving, the time spent, can face upward and can crouch, be competent to advance and retreat-at will, brought great enjoyment to the user.As required, the in parallel or use that is together in series of tool of also a plurality of assisteds can being swum, or make using simultaneously of multi-hull type for many people.

Claims

1, a kind of assisted swimming tool, by buoyancy aid 1, bearing block 2, crank 3 and axle 4, pedal 5,5 ', lashing 6 grades are partly formed, and it is characterized in that being connected with bearing block 2 at the tail end of buoyancy aid 1, axle 4 is contained in the bearing block 2 and can rotates flexibly, crank 3 and 4 one-tenths rigid attachment of axle, crank two rotating shafts 7,7 ' at a distance of 180 ° and in the same plane, pedal 5,5 ' respectively is contained in crank two rotating shafts 7,7 ' last and becomes hinged, and can rotate flexibly, the front end of buoyancy aid 1 is connected with lashing 6.

2, assisted swimming tool as claimed in claim 1, the front end that it is characterized in that buoyancy aid 1 is a sheet, tail end is 1 or several uiform section column body symmetric arrays, and be tightly connected along periphery by airtight film, on charge and discharge the gas valve, charge into the gas postforming, or make less than the material of water by density.

3, as claim 1,2 described assisted swimming tools, it is characterized in that the number of bearing block 2 and axle 4 is the same with the number of buoyancy aid 1 tail end uiform section column body; Bearing block 2 becomes movable and connects with buoyancy aid 1 tail end, and can only move forward and backward at uiform section column body upper edge axis direction, locatees during use.

4,, it is characterized in that buoyancy aid 1 can be overlapping by two identical parts, and be connected into an integral body in corresponding place as claim 1,2,3 described assisted swimming tools.
