Abstract
The invention relates to a breast stroke posture training machine employing a connecting rod in orbit constraint, belonging to the field of sport equipment; a four-connecting rod mechanism is employed to constrain the hand and foot orbits of breast stroke, and no motor is used so as to reduce the injury possibility of the practicers during the training process; supporting rods are used for supporting the wrists and ankles, so that the structure is simple and compact and that the orbit is accurate and normative; besides, the training machine can be used for guaranteeing the hands to approach the orbits on a spherical surface to be more anastomotic with the standard breast stroke action than a planar orbit; the training machine can be used by practicers with different heights and arm lengths, and the training machine has the advantages of easy control and operation, low cost and convenience for assembly and maintenance, so that the training machine is very suitable for the breast stroke beginners to train the swimming postures.
Description
Technical field
The present invention relates to the swimming instruction apparatus, the training device of particularly breaststroke standard action.
Background technology
Along with socioeconomic fast development, people's living standard improves constantly in recent years, adds that the success of Beijing Olympic Games is held, and in the middle of the people, has formed one physical culture upsurge.Particularly in flourishing city, when material life obtained greatly satisfying, people also in continuous growth, had formed multi-level, personalized sport consumption demand to the demand of healthy living.For the development in sport consumption market provides very big development space.
In the middle of numerous sports types, swimming as one be aim to build up health, to enrich the physical training that people's culture life is purpose, become one of people's favorite exercise project gradually.Adhere to swimming exercise, the function of systems such as nerve, breathing and blood circulation is improved, and can also improve muscle strength, speed, endurance and joint mobility, make health obtain coordinated development.What give birth to therefrom is the motion exercise apparatus on basis with the swimming exercise, also becomes an important starting point of motion Aided Machine research and development.
For swimming beginner; Device for exercising swim has special difficulty, and when beginning to learn, the beginner is usually because be difficult to overcome water funk psychology; More the technical key point of learn swim is said nothing of under the condition that people from natatorium crowds at present and has been learnt freely.Therefore when first learning swim, except the characteristic of understanding water, be familiar with the environment of water, the learner also will grasp the complete swimming technique action of a cover on the coast, so just can make the learner in the shortest time, grasp the most basic swimming technique and move and main points.In traditional swimming teaching, such training of stroke on the bank is to be with the learner to begin to learn from most basic breaststroke posture by the coach.But in all strokes, the breaststroke technical movements are the most complicated, and higher relatively to the harmony requirement of parts of body, therefore swimming difficulty concerning the beginner is bigger, and it is higher to start to walk.And this traditional oral instructions add the teaching method of demonstration, and the learner is difficult to accomplish standard, and do not have apparatus auxiliary, and the both arms both legs are unsettled, the exercise effort of getting up, and the learner is difficult to adhere to.But the technical movements of sports items need a large amount of exercises that repeat to realize skillfully.Therefore designing a kind of strokes of breaststroke on the bank exercising device guides and helps people to carry out the stroke exercise; Not only can alleviate the demand pressure of natatorium to a certain extent; And can also help the beginner to grasp correct swimming position well, cross the first road threshold of device for exercising swim as early as possible.
The action of the space of swimming exercise hand is complex spatial track very.The existing a kind of device that can realize simulation swimming hand exercise, like Chinese invention patent CN200951304 Land Training Simulator for Breast Stroke, this exercise simulator is made up of the hand stopping means of peach shape, bearing platform, leg-supporting stopping means etc.During use; The practitioner is prostrate on the bearing platform panel; Utilize the hand stopping means of peach shape to help the practitioner to accomplish correct arm movement, hand is according to the orbital motion of peach shape fiber plant during the exercise arm pull, and the target location bar of kicking one's legs helps the practitioner to accomplish correct thrust kick; Footmuff slides in chute when kicking one's legs, owing to trapped orbit is arranged so helped the practitioner to grasp correct swimming position.
This exercising machine peach shape track floor space is big, and has adopted planar obit simulation to come the motion of guide people, and does not meet professional stroke; And this guide rail realize the striking device of track that utilizes can not be realized the coordination of trick campaign, thereby unsatisfactory when the aiming drill person learns the breaststroke stroke.
