Abstract

A tubular tension exerciser for physical training of arms and legs features structurally that an elastic rubber band passing through a straight hard tube is fixed to one end of the tube and the free end of elastic rubber band is extended via a pulley from the opening at the another end of the tube and connected with a soft ring. The length of tube is equal to that of two arms. Its advantages are the physical training of both arms and legs in different directions and no need of suspending hook.

Description

Tube type chest-expander

The present invention relates to sports apparatus, be specifically related to chest expander.

According to market survey, for a long time, body-building chest expander commonly used is a steel strand exerciser.This chest expander is between the annular handle of two hard several extension springs to be housed, and utilizes the elasticity of extension spring to do the pulling force activity.There are many defectives in this chest expander, mainly is:

1. the folk prescription that can only do from inside to outside moves to pulling force;

2. the pulling force of upper limbs can only be done, the pulling force of lower limb can not be done;

3. when one hand drew an end, the other end must have hook to fix; And the position of fixing point is according to action request, needs below or the side, needs overhead places such as top sometimes, and this all is difficult to accomplish under many circumstances, thereby has limited the performance of its function greatly.

Purpose of the present invention: make chest expander not only can do the action of drawing from inside to outside, but also want and to draw from outside to inside; Needn't establish fixing points such as hook during use in addition, so that under general environment, can both conveniently use; On function, increase the diversity that is suitable for action, especially will increase the function that is applicable to leg movements.

The object of the present invention is achieved like this: (1) replaces spring with elastic adhesive tape; (2) adopting the straight tube of hard is supporter, and adhesive tape is installed in the straight tube; (3) end of adhesive tape is fixed in an end of straight tube, and the other end of adhesive tape is drawn in by pipe through the pulley at straight tube other end lateral opening place; (4) exit of adhesive tape connects a soft draw ring.(5) there is articulation at the middle part of straight tube, straight tube can be splitted into two sections uses.Do explanation now in conjunction with the embodiments, and with reference to accompanying drawing:

Fig. 1 makes the situation map of shank pulling force with tube type chest-expander;

Fig. 2 tube type chest-expander embodiment front view;

Fig. 3 tube type chest-expander embodiment side view.

Mark among the figure: 1. horizontal handle; 2. the opening of straight tube side and the pulley adorned; 3. soft drawn ring; 4. adhesive tape; 5. straight tube; 6. articulation.

Elastic adhesive tape 4 is within the straight tube 5 among the figure.One end of adhesive tape 4 is fixed in straight tube one end; There is an opening other end side of straight tube and pulley 2 is housed.The other end of adhesive tape and connects a soft drawn ring 3 outside pulley 2 fairleads.There is articulation 6 at pipe shaft middle part, can be thus with straight tube from being divided into two sections.There is short horizontal handle 1 at two of pipe and is 〃 T 〃 font with straight tube.Pipe range can satisfy the Breadth Maximum that two arm sides are stretched.The internal diameter of pipe can allow adhesive tape freely to stretch; The external diameter of pipe can satisfy the requirement of strength of pipe shaft and be suitable for holding.

Owing to taked such scheme, function ratio steel strand exerciser of the present invention greatly strengthens.Now illustrate according to the action that is suitable for:

1. two arm sides are stretched, and one holds the soft drawn ring, and one holds the end that straight tube does not have pulley, and at this moment straight tube lies across the front, when two hands from outside to inside when drawing, adhesive tape is stretched, and pulls out through pulley, make two hands close, realize the activity that two arms draw from outside to inside, this is that steel strand exerciser is not accomplished;

2. this apparatus is stood on ground, there is pulley end upwards, body hold a writing brush or pen-write on the other hand in the front near the pulley place, another holds the soft drawn ring, draws adhesive tape to stretch, and can realize that two arms draw from inside to outside, though steel strand exerciser also can be done this action, but the amplitude of action is little, because it can only be begun to draw by the scope beyond the length of apparatus itself, and this apparatus can be begun to draw by the close position of two hands;

The hand of body props up motionlessly forward if hold a writing brush or pen-write, and the hand of holding draw ring can be done the single armed pulling force activity of arbitrary multiple direction, if do this action with steel strand exerciser, at this moment need have fixing point forwardly;

3. one hand straight tube, make that straight tube is flat to be stretched, prop up preceding or after one's death the wall of body with an end of no pulley, another is held the soft drawn ring and draws the adhesive tape stretching, extension, can do imitative multiple pulling force action such as throws, strike, these actions just can be made as if all having hook to tangle an end earlier of steel strand exerciser;

4. two handgrips are lived a end that this apparatus do not have pulley in the waist side, will have an end of pulley to be affixed on ground after one's death, and pulley is lived sole with the soft drawn ring set down, draws adhesive tape overhanging with pin, can action such as draw do swinging kick, and this action steel strand exerciser can't be done; (referring to Fig. 1)

5. be two joints partly therefrom with straight tube, adhesive tape between two joints is exposed, and the adhesive tape that will expose with pin slams, hold the two ends or the pipe shaft appropriate location of pipe, former being fixed of an end of adhesive tape at this moment, the handle of the other end is stuck in the pulley place, also just be fixed, so two arms can make side raise simultaneously, to front raise and activity such as shrug, this is equivalent to two steel strand exercisers and works simultaneously.

In order to adapt to different tension intensity requirements, can two adhesive tape that tension intensity is different be installed simultaneously in a straight tube, allow it respectively outside the two ends fairlead by straight tube, select for use arbitrarily during use.

The soft drawn ring that the adhesive tape exit is used mainly is for the ease of the cover sole, so that do leg action not; Therefore, can connect the short handle of a joint hard simultaneously so that can select use when pulling.

In a word, the present invention mainly has the following advantages than steel strand exerciser:

1. not only can do the action of drawing from inside to outside, and can do from outside to inside and draw, overcome and to have drawn from inside to outside Limitation, make pulling force action variation;

2. can do the pulling force activity of shank, overcome the limitation that to do the upper limbs activity;

3. need not to establish in addition fixing points such as hook when using, be convenient to bring into play multiple function.

Claims (1)

1. The tube type chest-expander that utilizes object elasticity to make is characterized by:

   A. with resilient adhesive tape in the straight tube of hard;

   B. an end of adhesive tape is fixed in the end in the straight tube;

   C. the other end of adhesive tape by the opening part of straight tube other end side, outside the pulley fairlead, and connects a soft drawn ring.
