Description

Back exercising unit

The utility model relates to the exercise facility.

Though existing body-building facility variety type is quite a lot of,, and carry, collect inconvenient mostly because structure belongs to maximization, and not only price is high.

The purpose of this utility model provides a kind of more small-sized and still be convenient to the Back exercising unit moving, collect.

The purpose of this utility model is achieved in that Back exercising unit, it is made up of the underframe that a forward and backward straight-bar and two cross bars overlapping constitute, it is characterized in that: the cross bar front end in this underframe is provided with a triangular shape backplate, backplate is established open-work, be inserted in by the fixed bar that lamellar body connects for two root edges, the open-work that wears backplate with bolt is locked on the screw of lamellar body, and it is skewed that fixed bar is; The top of this fixed bar is articulated with a body of rod, and in the periphery of the body of rod with a square frame, for locking one cushion, it is that fulcrum is forward and backward swing shape that square frame is able to fixed bar; The middle position of the cross bar of underframe is provided with another straight-bar, connects a vertical U-shaped sleeve in straight-bar, and open-work is established in sleeve side bottom, and establishes through hole in T shape bar vertical component effect, and this T shape bar stands on sleeve or stubborn backward folding horizontal; The rear end of underframe cross bar then is provided with a U-shaped bar, connects a square frame in this U-shaped bar pivot, and in this square frame seat cushion that locks, these seat cushion front end central authorities are connected in the body of rod root edge of underframe front end with the connecting rod of a bending.

By the combination of above-mentioned member, the user can hold the side lever of square frame, and sits and to crouch in seat cushion, by the continuous action relation of its seat cushion and square frame, can constitute bend over, motions such as inclination and stretching, extension, and folding in view of the above reaches than miniaturization and the effect being convenient to move.

Below by drawings and Examples the utility model is described further again:

Fig. 1 is the utility model schematic perspective view;

Fig. 2 is the utility model perspective exploded view;

Fig. 3-8 is depicted as the utility model operation schematic perspective view;

Fig. 9 is the utility model folding state schematic diagram;

Shown in Fig. 1-2: the utility model is made up of the underframe that a forward and backward straight- bar 11,12 and two cross bars, 13 overlappings constitute, it is characterized in that: the cross bar front end in this underframe is provided with a triangular shape backplate 14, backplate 14 is established open-work 141, be inserted in by the fixed bar 16 that lamellar body 15 connects for two root edges, the open-work 141 that wears backplate 14 with bolt 17 is locked on the screw 151 of lamellar body 15, and fixed bar 16 is skewed; The top of this fixed bar 16 is articulated with a body of rod 21, and in the periphery of the body of rod 21 with a square frame 22, for locking one cushion 23, square frame 22 is able to fixed bar 16 and is forward and backward swing shape for fulcrum, and the middle position of the cross bar 13 of underframe is provided with another straight-bar 18, connect a vertical U-shaped sleeve 31 in straight-bar 18, open-work 311,312 is established in sleeve 31 side bottoms, and establishes through hole 321,322 in T shape bar 32 vertical component effects, and this T shape bar 32 stands on sleeve 31 or stubborn backward folding horizontal; The rear end of underframe cross bar 13 then is provided with a U-shaped bar 41, articulates a square frame 42 in this U-shaped bar 41, and in this square frame 42 lockings one seat cushion 43, these seat cushion 43 front end central authorities are connected in the body of rod 21 root edges of underframe front end with the connecting rod 45 of a bending.Wherein, what the vertical component effect of this T shape bar 32 was provided with is the through hole 321,322 that is correspondence position with the open-work 311,312 of sleeve 31, and be placed on the vertical component effect of T type bar 32 with a spheroid 33 and spring 34, and make spheroid 33 for being exposed to through hole 321, the vertical component effect of T shape bar 32 is inserted in the sleeve 31, worn fixingly by open-work 312, through hole 322 with bolt 35, and when spheroid 33 broke away from open-works 321, T shape bar 32 was stubborn folding horizontal downwards.Wherein, the front end of this square frame 42 is provided with the loop bar that bends inwards and in loop bar, on be nested with soft packing ring 44, be beneficial to amounting to of square frame 42 and place.Wherein, be connected in the middle position of U-shaped bar 41 with a spring oil hydraulic cylinder 46, thereby constitute Back exercising unit 1 in the body of rod 21 root edges.

Shown in Fig. 3,4: during use, can hold the side lever of square frame 22, foot is against seat cushion 43, or to ride in forward and backward straight- bar 11,12, to front lower place backfin square frame, the body-building of bending over.

Shown in Fig. 5-8: can be seated at seat cushion 43, reverse grip square frame 22 side levers are the shape that couches, exercise motion such as formation is lain on the back, stretching, extension.

As shown in Figure 9: during the utility model folding, T shape bar 32 is rolled over backward, square frame 22 and seat cushion 43 are the horizontal shape respectively to invagination, take up space less, and are convenient to collection, carrying.
