Description

The tensioner of chest expanding and lift exercise

The utility model relates to a kind of device that is used for chest expanding and lift exercise.

As shown in Figure 1, chest expanding in the past, lift exercise machine 10 is an example, be to have set up a stand 12 at a pedestal 11 end faces, this stand 12 is installed with a seat cushion 13 and has set up two slide bars 14 at nearly end section in nearly middle section, this two slide bar 14 can be for several balancing weight 15 sliding putting, and these stand 11 tops are provided with a cross bar 111, it is distolateral at cross bar 111 to expand act swing arm 16 pivots knot for two, each lifts swing arm 16 can be in the past, the back expansion reaches, following act is lifted, and each expands act swing arm 16 tops binding a cable wire 17, it is affixed with balancing weight 15 that each cable wire 17 sees through pulley 18 guidings, makes expansion lift swing arm 16 and form interlock with balancing weight 15.The user rides in seat cushion 13 end faces, fasten expansion act swing arm 16 with the both arms retaining and do forward and backward expansion or upper and lower action of praising, weight pulling force by balancing weight 15, make both arms obtain different expansions, praise amount of exercise, though though above-mentioned structure can reach the purpose of motion, but, during actual the use, still have following shortcoming.

Because the weight pulling force of this expansion act swing arm 16 is the quantity decisions with balancing weight 15, but, the balancing weight 15 of common metal material has suitable weight and volume, and balancing weight 15 weight and volume can not change, in addition, though this expands the weight pulling force of lifting swing arm 16 can be by the cooperation start decision of cable wire 17 and pulley 18, but change cable wire 17 and pulley 18, can make this chest expanding in the past, the weight of lift exercise machine 10 integral body, the volume of timber significantly promotes, make the carrying cost increase, in addition, during carrying or carry additionally, inconvenience during unloading balancing weight 15, and this balancing weight 15 is whenever lifted in the swing arm 16 with expanding, following slide action once just can produce noise because of colliding mutually, therefore, also impracticable and inconvenient in the use.

The purpose of this utility model is to provide a kind of can reduce the convenience that whole counterweight, volume and raising are carried additionally or unloaded, and reduces the chest expanding of noise and the tensioner of lift exercise.

The tensioner of chest expanding of the present utility model and lift exercise, be to have set up a stand in a base top surface, this stand sets firmly a seat cushion near the middle section, and the top is provided with a cross bar, the distolateral pivot knot two of this cross bar expands lifts swing arm, it is characterized in that: this stand has laterally provided a fulcrum near top section place, and this shaft end is provided with a guide wheel; This expansion is lifted the swing arm back side and is located to be provided with respectively a crotch near the both sides of top section; This fulcrum and this expansion are lifted between the swing arm and are provided with several elastic woven tapes, and this elastic woven tape is provided with a hook at forward and backward two ends respectively, the guide wheel of this elastic woven tape pile warp fulcrum, and the upper and lower overlapping of this hook is hooked on the crotch that swing arm is lifted in this expansion.

The tensioner of described chest expanding and lift exercise is characterized in that:

The latter end of this fulcrum is equipped with a guide rod, and to should guide rod place spiral shell being provided with bolt, the end of this guide rod and this a guide wheel pivot knot that this guide rod is screwed tight the location.

The tensioner of chest expanding of the present utility model and lift exercise need only increase, subtract the use amount of elastic woven tape, just can make to expand to lift swing arm and have different expansions or praise the weight pulling force.Therefore, utilize matter soft and light and have the elastic woven tape of elasticity tension, except can reducing whole weight and volume, more can improve convenience when carrying additionally or unloading, and can reduce noise.

In sum, the tensioner of chest expanding of the present utility model and lift exercise is the balancing weight 15 that replaces in the past with elastic woven tape 50, because these elastic woven tape 50 matter are soft and light, and has the pulling force that swing arm 40 is lifted in the expansion can controlled equally with this balancing weight 15, can conveniently fold again and fold, therefore, except can reducing whole counterweight, the volume of timber, carry additionally or have convenience when unloading elastic woven tape 50, and reduce the noise that expands when lifting swing arm 40.

Be elaborated below by Cui embodiment and accompanying drawing tensioner to chest expanding of the present utility model and lift exercise, in the accompanying drawing:

Fig. 1 is the schematic perspective view of the tensioner of in the past chest expanding, lift exercise.

Fig. 2 is the schematic perspective view of the utility model than Cui embodiment.

Fig. 3 is the above-mentioned schematic perspective view than Cui embodiment part of the utility model.

Fig. 4 is the above-mentioned combination schematic diagram than Cui embodiment of the utility model.

Fig. 5 is the above-mentioned schematic diagram of carrying additionally elastic woven tape than Cui embodiment of the utility model.

Shown in Fig. 2,3, the tensioner of chest expanding of the present utility model and lift exercise, comprise that a pedestal 20, a fulcrum 30, two expand act swing arm 40 and several elastic woven tapes 50, these pedestal 20 end faces have set up a stand 21, one seat cushion 22 is installed in the nearly middle section of this stand 21, these stand 21 tops are provided with a cross bar 23, two expand act swing arm 40 pivots knot in these cross bar 23 both sides, each expand to be lifted swing arm 40 and has the use effect that forward and backward expansion and upper and lower act are lifted, this pedestal 20, expand to lift swing arm 40 identical with in the past member, no longer adds to narrate.

This fulcrum 30 laterally provides in stand 21 near top section place, and is equipped with a guide rod 31 at latter end, to being provided with a location bolt 32 by guide rod 31 place's spiral shells, making this guide rod 31 be subjected to bolt 32 packings and locate, and these guide rod 31 ends is pivoted with a guide wheel 33.

The back side that swing arm 40 is lifted in this expansion is provided with a crotch 41 respectively near place, section both sides, top.

The forward and backward two ends of each elastic woven tape 50 are respectively equipped with a

hook

51,52, behind the guide wheel 33 of this this fulcrum 30 of elastic woven tape 50 pile warps, are hooked on each respectively and expand the crotch 41 of lifting swing arm 40 back sides.

Above-mentioned is that the utility model is than Cui embodiment, during assembling, shown in Fig. 4,5, at first, the hook 51 of these elastic woven tape 50 1 ends need only be colluded in the crotch 41 that is located at an expansion act swing arm 40, behind the guide wheel 33 with this this fulcrum 30 of elastic woven tape 50 pile warps, collude in the crotch 41 that is located at another expansion act swing arm 40 again with the hook 52 of the other end, just can locate this elastic woven tape 50, the elasticity tension tractive of mat elastic woven tape 50 expands lifts swing arm 40.When the user is sitting in seat cushion 22 end faces, fasten expansion with the both arms retaining and lift swing arm 40, bestow a forward and backward expansion or upper and lower action of praising, by the elasticity tension of elastic woven tape 50, make both arms obtain different expansions, praise amount of exercise, with strong dorsal muscles, arm flesh, chest muscle etc.

In addition, the user can be on demand, the upper and lower respectively overlapping of several elastic woven tapes 50 is hooked on two expand lifts 41 of the crotches of swing arms 40, this expansions act swing arm 40 can allow the user produce different expansions, praise amount of exercise because of the increase and decrease of elastic woven tape 50 use amounts, to reach different training effects.And, but also this bolt 32 of pine oil of user, flexible this guide rod 31 is to Len req, screw this bolt 32 packing guide rods 31 again, make this guide rod 31 in leading the process of moving, can support or unclasp elastic woven tape 50, and can adjust the elasticity tension of elastic woven tape 50.
