Abstract

The utility model relates to a pipe type chest-expander for exercising activities. An elastic rubber strip is arranged in a hard straight pipe; one end of the rubber strip is fixed on end in the pipe, and the other end of the rubber strip is led out from an opening on the side surface of the other end of the straight pipe through a pulley and is connected with a soft pull ring; short handles are arranged on both ends of the straight pipe and form T shapes; the pipe length is about equal to the maximum width when two arms are sidewards extended. The utility model has the functions that the two arms can form tension which is from inner to exterior and can also form the tension which is from the exterior to the inner; the actions, such as leg tension and a plurality of tension actions can be carried out by using the ground or the wall as the support; the limitation that the spring chest-developer can only form unidirectional tension and can only form upper limb tension is broken through, and the inconvenience that some actions need hooks is also broken through.

Description

Tube type chest-expander

The utility model relates to sports apparatus, is specifically related to chest expander.

According to market survey, for a long time, there are many defectives in the chest expander that body-building is commonly used.With modal steel strand exerciser is example, and it is that several extension springs are housed between the handle of two hard, utilizes the elasticity of extension spring can do the pulling force activity.This chest expander mainly contains following defective:

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.

The purpose of this utility model: make chest expander not only can do the action of drawing from inside to outside, and 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, enlarge applicable scope, especially will increase the function that is applicable to leg movements.

The purpose of this utility model is achieved in that (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 pulley; (4) exit of adhesive tape connects a soft draw ring.(5) but the straight tube merogenesis.Do explanation now in conjunction with the embodiments, and with reference to accompanying drawing:

Fig. 1 tube type chest-expander embodiment front view;

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

Fig. 3 tube type chest-expander embodiment is equipped with the enlarged drawing of an end of pulley.

Mark among the figure: 1. horizontal handle; 2. straight tube is equipped with the opening of pulley; 3. soft drawn ring; 4. adhesive tape; 5. straight tube; 6. articulation; 7. supply the opening of adhesive tape one end hook.

Elastic adhesive tape 4 is within the straight tube 5 in the drawings.One end side surface of pipe has an opening and pulley 2 is housed.One end of adhesive tape 4 is hung on the other end opening part 7 of pipe by hook.The other end of adhesive tape is drawn and is connected a soft drawn ring 3 through pulley 2.Pipe shaft has three articulations 6, can thus straight tube be divided equally from the centre to be two sections or to be divided into four 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 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 utility model has strengthened.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.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, makes two hands close, realizes 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, have pulley end upwards, protracting on the other hand holds a writing brush or pen-write body near the pulley place, and another holds the soft drawn ring, draws adhesive tape to stretch, and can realize that two arms draw from inside to outside, and actuating range is bigger than steel strand exerciser.

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, at this moment need there be fixing point forwardly with steel strand exerciser;

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, and the end bias laid that pulley will be arranged is 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.This action steel strand exerciser can't be done;

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, at this moment former being fixed of an end of adhesive tape, the soft drawn hand of the other end is stuck in the pulley place, also just has been 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.

The present embodiment straight tube can be divided into four joints at most, is for collapsible, is easy to carry.

In a word, the utility model 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;

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.
