Description

The rowing exercise equipment of adjustable impedance

Technical field

The present invention relates to a kind of sport and body-building equipment, relate in particular to a kind of rowing exercise equipment that moves smooth and easy and adjustable impedance, so as to promoting the training effect of rowing exercise equipment.

Background technology

Point out according to medical research; Motion mode on a small quantity and repeatedly; The effect of its prevention of cardiac and intensive the segment length's time of doing move the same good; Also therefore the industry exploitation has multiple body-building equipment, supplies the user to carry out body building on demand, like exercycle, treadmill, ski machine, rowing exercise equipment, oval trailer, treadmills or the like.And all kinds of body-building equipments have its different training effect, are example with the rowing exercise equipment, are to be provided with a slide rail in a pedestal; And slide rail is provided with an alternative seat cushion group of sliding; And pedestal in addition end be provided with one supply user's both feet to trample the pedal group, pedestal and be provided with in seat cushion group both sides supplies the user to carry out the joystick group of bent rowing again, so lets the user shore the pedal group with both feet and makes slippage before and after the seat cushion group; And cooperate both hands to utilize the PROPEL of rowing the boat of the front and back push-and-pull that the joystick group produced; It mainly is the action of rowing the boat by simulation, to strengthen the muscle at hand, leg, chest, waist and back, the omnibearing training airplane of can saying so;

And the joystick group of traditional rowing exercise equipment is also outwards to enclose respectively in slide rail front end both sides to be connected to a jib; Jib is articulated with a joystick in the position, termination with universal joint; Be connected with an oil compression rod between joystick and jib and with the pivot block pivot; Temporarily transfer whole pedal group and seat cushion group and make to become fix or pattern slidably, cooperate with universal joint and pivot block and impel joystick can form the swing application of force of solid space, can simulate the exercise practicality of body-building effectiveness of actual bent rowing and the motion of changeableization of tool to reach.But the universal pin-jointed structure of this kind includes a plurality of pin connected assemblies, though can make things convenient for folding, increases the member of assembling, and significantly improves the probability of damaging in the use.It utilizes oil compression rod to produce hindrance function simultaneously, and it in use can have oil compression rod compression direction and the inconsistent phenomenon of joystick direction of action, and the situation that causes its action to have some setbacks possibly cause unnecessary athletic injury.Simultaneously its oil compression rod is because of being to use hydraulic oil as the impedance medium, and its impedance is that the density by hydraulic oil decides, but the hydraulic oil density of oil compression rod can receive the intensification before and after using again and change, so it can have influence on the training effect of integral body.Moreover the prior oil pressure bar mostly can't adjust its impedance, and can't meet different users's different motion demand.

Edge is; The inventor deeply inquires into to the problem that aforementioned existing rowing exercise equipment is faced in use; And by the demand of the experience of being engaged in research and development for many years and use, and actively seek solution, through the research of constantly making great efforts with study; Finally the rowing exercise equipment of developing a kind of adjustable impedance of success has some setbacks and can't regulate the shortcoming that impedance causes so as to overcoming existing rowing exercise equipment action.

Summary of the invention

Technical problem underlying to be solved by this invention is; Overcome the above-mentioned defective that prior art exists; And a kind of rowing exercise equipment of adjustable impedance is provided, but so as to making not only saving member of rowing exercise equipment, and can promote the smoothness of molar behavior; It is the impedance of adjustment movement effectively, further effectively promotes its training effect.
