Abstract

An arm exercise device is provided with two support bodies. A cylindrical cross rod is fixedly connected between the two support bodies at the positions of upper ends, a rotating body capable of rotating around the cross rod is sleeved on the cross rod and is a regular eight-angular prism with the peripheral contour of the cross section in a regular octagon, and each side of the regular eight-angular prism of the rotating body is provided with a plurality of ball coronary protrusions which are in a row and are distributed at intervals. The plurality of protrusions are divided into a plurality of first protrusions with the same dimensions and a plurality of second protrusions with the same dimensions, the first protrusions and the second protrusions are alternately arranged, and each first protrusion is 3-5mm higher than each second protrusion. The arm exercise device can be used for massaging and stimulating arms, and is moderate and soft in acting force, good in exercise effect, simultaneously simple in structure and practical.

Description

A kind of arm motion apparatus

Technical field

The utility model relates to a kind of health and fitness facilities, particularly a kind of arm motion apparatus.

Background technology

At present, the apparatus that is used for body-building is more, but most of complex structure, cost are high, and it is less to be used for the apparatus of arm motion.CN102309834A discloses the oval sports apparatus that waits hand motion trajectory of a kind of containing (closely), it by to the sports apparatus that contains reciprocating oscillating rod type man-operated mechanism (such as elliptical machine; Contain the exercycle, treadmills of man-operated mechanism etc.) carry out necessary structure innovation, make the original swing center take fork of handle mechanism be reciprocal " eclipsed form " circular motion track in the center of circle, the movement locus that becomes the reciprocating type hands movement track that forms when originally holding fork and other form is superimposed, thereby the compound motion track that forms hand can be the forms such as (or can closely be) ellipse, circle, can form like this motion morphology of coordination and the better arm of conformability, upper body and even whole body.CN2462904 discloses a kind of leg exerciser, comprises a body, a drive system and a shank bolster.Drive system comprises a drive unit, a spinner member, a trace, a guide element and a guiding frame, and then can produce sliding suitable horizontal 8-shaped smooth curve reciprocating motion, overcome the shortcoming of the sharp-pointed fold return motion mode of commonly using the horizontal structure movable type, make whole motion path similar one horizontal 8-shaped smooth curve, meet the sports medical science principle.How these technology are for making the sports apparatus can be to arm-massage, stimulation, and active force is moderate, simple in structure, practical, does not provide concrete guidance program.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of arm motion apparatus is provided, and it can be to arm-massage, stimulation, and active force is moderate, soft, and movement effects is good, and it is simple in structure simultaneously, practicality.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:

A kind of arm motion apparatus, have two supporters, its technical scheme be between described two supporters in the top the position be fixedly connected with a tubular cross bar, being set with on the cross bar can be along the rotor of this cross bar rotation, described rotor is that the peripheral contour shape of cross section is positive eight prisms of octagon, all have a row on each side of positive eight prisms of described rotor and be spaced apart, a plurality of projections of spherical crown shape, described these a plurality of projections are divided into measure-alike a plurality of the first projections, measure-alike a plurality of the second projections, each first projection is alternately setting with each second projection, and each second projection of each first convexity exceeds 3 ~ 5 millimeters.

In the technique scheme, described each second projection of each first convexity preferably exceeds 3.5 millimeters.

Between two supporters described in the utility model in the top the position be fixedly connected with a tubular cross bar, being set with on the cross bar can be along the rotor of this cross bar rotation, described rotor is that the peripheral contour shape of cross section is positive eight prisms of octagon, all have a row on each side of positive eight prisms of described rotor and be spaced apart, a plurality of projections of spherical crown shape, described these a plurality of projections are divided into measure-alike a plurality of the first projections, measure-alike a plurality of the second projections, each first projection is alternately setting with each second projection, and each second projection of each first convexity exceeds 3 ~ 5 millimeters.

Like this, when using this practicality new, palm turned downwards that arm is placed on the rotor along the direction vertical with rotor for the user, and arm is stretched back and forth and bending, rotate around cross bar thereby drive rotor, realized that arm contacts with the face of rotor and the first projection, the second projection to massage, the stimulation of arm, through testing, its active force (stimulation power) is moderate, soft, the utility model is comfortable and movement effects good, and result of use is good, and it is simple in structure simultaneously, economical and practical, easy to use.

In sum, the utility model can be to arm-massage, stimulation, and active force is moderate, soft, and movement effects is good, and it is simple in structure simultaneously, practicality.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 be among Fig. 1 rotor 3(and the projection 4, cross bar 2) the cutaway view along the A-A line.

The specific embodiment

Such as Fig. 1, shown in Figure 2, the utlity model has two supporters 1, between described two supporters 1 in the top the position be fixedly connected with a tubular cross bar 2, being set with on the cross bar 2 can be along the rotor 3 of this cross bar rotation, described rotor 3 is that the peripheral contour shape of cross section is positive eight prisms of octagon, all have a row on each side of positive eight prisms of described rotor 3 and be spaced apart, a plurality of protruding 4 of spherical crown shape, described this a plurality of protruding 4 is divided into measure-alike a plurality of the first projections 41, measure-alike a plurality of the second projections 42, each first projection 41 is alternately with each second projection 42 and arranges, and each first projection 41 exceeds 3 ~ 5 millimeters than each second projection 42.Above-mentioned each first projection 41 can exceed 3.5 millimeters than each second projection 42.Above-mentioned the first projection, the second projection can be connected (perhaps pegging graft) on each side of positive eight prisms of rotor 3.Above-mentioned supporter can be made by steel pipe and pedestal, and cross bar can be made by steel pipe, and rotor, the first projection, the second projection can be made by wood materials (such as pure pine or Chinese prickly ash trunk or Chinese wax bar), can also be made by other material.
