Abstract

The utility model relates to a tread water training device for swimming. A supporting frame which can be clamped under the armpits of trained persons is connected to a hanging frame on the inner side of a cylinder body; a porous pedal is arranged in the cylinder body; a floating body is arranged under the pedal; one end of a pulling rope is fixed under the floating body; the pulling rope rounds a group of fixed pulleys; one end is led to the external of the cylinder body for fixing and adjusting the height positions of the floating body and the pedal in the cylinder body. The utility model has the advantages of small occupied area and less water consumption, and has the advantage that the safety of the trained persons for the tread water is ensured.

Description

The swimming training aids of treading

The utility model relates to a kind of device of training swimming to tread.

Learning swim must be to swimming pool or rivers,lakes and seas, and potential range is far away or certain risk arranged, child's learning swim of kindergarten especially, and the nurse is difficult to look after exhaustively, and danger is big relatively.So the kindergarten is difficult to organize child collective learning swim.In fact the child just has been able to swim substantially at last as long as association treads.

The purpose of the utility model provide a kind of take up space little, the few and swimming that can guarantee trainer's safety of the water consumption training aids of treading.

The swimming described in the utility model training aids of treading, a cylindrical shell is arranged, the interior side of cylindrical shell is hanger fixedly, connect a pedestal on the hanger, hinge bracket on the pedestal, pedestal front end have supporting plate restriction carriage turns parallel with horizontal plane to position, the end, are placed with the pedal of a plurality of through holes in the cylindrical shell, pedal is placed down buoyancy aid, and the drag rope under the buoyancy aid is fixed on cylindrical shell by one group of fixed pulley on the cylindrical shell, and to limit buoyancy aid outward floating.

The described training aids of treading, take up an area of for a short time, water consumption is few.The pedal that is supported by buoyancy aid is arranged at the bottom of it, and barrel has the carriage that can be sandwiched in the trainer oxter, and very water funk child also can make it feel very safe for training.Can first payout during use, make the buoyancy aid sustain pedal floating near the water surface, make the people feel that water is very shallow.The trainer enters in the cylindrical shell, and drag rope makes pedal sink to the appropriate location, and carriage is placed the trainer oxter.Carriage is guaranteed that by the supporting plate restriction carriage is not less than level.When the trainer has grasped the skill of treading, self make progress when floating, carriage can slightly upwards rotate with human body, or breaks away from carriage fully.This training aids can guarantee trainer's safety.

The tread cross-sectional schematic of training aids of Fig. 1;

Fig. 2 is the schematic top plan view of Fig. 1.

Cylindrical shell 1 one sides are hanger 3 fixedly, and the staircase 2 outside hanger 3 and the cylindrical shell 1 is connected as a single entity.Pedestal 4 is inserted on the hanger 3, and carriage 5 is hinged with pedestal 4, and the supporting plate 4a of pedestal 4 front ends is in that restriction carriage 5 rotates under the carriage 5.Hanger 3 has a plurality of pegs, so that adjust the position of carriage 5.Pedal 9 places cylindrical shell, and a plurality of through holes 10 are arranged on the pedal 9, and pedal 9 has guide plate 12 so that pedal can not be turned on one's side, and buoyancy aid 11 places under the pedal, and buoyancy aid can be a lifebuoy, also can be kickboard.11 times fixing drag ropes 13 of buoyancy aid are fixed on outside the cylindrical shell by the one group of fixed pulley 6 that is fixed on the cylindrical shell.The lanyard of present embodiment is the inserted block 8 that a porous is housed outside cylindrical shell, and rope 13 1 ends are fixed on the inserting handle 7, and inserting handle 7 can insert among some hole 8a of inserted block 8, to adjust the height and position of pedal 9 in cylindrical shell.Certainly also can adopt multiple other modes that rope 13 1 ends are tightened up outside cylindrical shell 1.

Claims (1)

1, the swimming training aids of treading, it is characterized in that, a cylindrical shell (1) is arranged, the interior side of cylindrical shell is hanger (3) fixedly, connect a pedestal (4) on the hanger, hinge bracket on the pedestal (5), it is parallel with horizontal plane that pedestal (4) front end has supporting plate (4a) restriction carriage (5) to turn to extreme lower position, be placed with the pedal (9) of a plurality of through holes in the cylindrical shell (1), the following buoyancy aid (11) of placing of pedal (9), the drag rope under the buoyancy aid (13) is fixed on cylindrical shell (1) by the one group of fixed pulley (6) on the cylindrical shell, and restriction buoyancy aid (11) is floating outward.
