Abstract

The utility model discloses a power roller which comprises a shell and handles. A middle shaft is connected in the shell in a pivotal mode, and a spring sleeve which cannot rotate is fixed to the middle shaft. A spring is arranged on the spring sleeve in a sleeved mode, and the two ends of the spring are connected to the shell and the spring sleeve respectively. Meanwhile, the handles are two in number and fixed on the left end face and the right end face of the middle shaft respectively. After the power roller is optimized, the shell is in the shape of a drum, and the handles are bent downwards relative to the axis of the middle shaft. The power roller has the advantages of being simple in structure, easy to manufacture, flexible in rolling and comfortable in use.

Description

Power roller

Technical field

The present invention relates to body-building apparatus technical field, especially relate to a kind of power roller.

Background technology

Power roller is a kind of extremely welcome sports equipment occurring at present.General, this power roller comprises shell and 2 handles, and this handle can rotate with respect to this shell.Like this, person taking exercise in use, takes kneeling position to kneel on ground, and both hands grip respectively a handle, forwards lie prone down afterwards, this power roller rolls forward, until person taking exercise lies prone, pours on ground, then again to reclaiming power roller, people also and then erects, and returns to kneeling position.That is, repeatedly, after aforementioned activities, person taking exercise's belly has been carried out to good exercise.Its defect is: 1, complex structure, prepare loaded down with trivial details.2, this power roller only can straightly roll forward, underaction.3, handle is easy to be rotated in company with shell, uses comfortable not.

Summary of the invention

The object of this invention is to provide a kind of power roller, it has simple in structure, is easy to the feature of preparation.Further, it also has rolls flexibly, uses comfortable feature.

The technical solution adopted in the present invention is: power roller, comprise shell and handle, in described shell, be articulated with jackshaft, the non-rotatable spring housing that is fixed with on this jackshaft, on this spring housing, cover has spring, and the two ends of this spring are connected on this shell and this spring housing, and meanwhile, this handle is 2 and is individually fixed on the left and right end face of this jackshaft.

Described shell is cydariform.

The outside of described shell is provided with skid resistant course.

Described handle is connected on the end face of this jackshaft.

Described handle bends downwards with respect to the axial line of this jackshaft.

The advantage that the present invention has is: 1, simple in structure, be easy to preparation.The jackshaft that power roller of the present invention is connected this shell and is positioned at this enclosure by spring, thus without compared with multi-part, structure is comparatively simple, is easy to preparation.And, this spring housing on this jackshaft, thereby only need to select comparatively suitable spring, can guarantee that this power roller has preferably restoring force.2, roll flexibly.This shell is cydariform, thus the straight rolling forward of this power roller, and can be flexibly to left front, right front rolling.3, use comfortable.This handle bends downwards with respect to the axial line of this jackshaft, thereby under the effect of human bady gravitational, this handle is difficult for rotating in company with this shell.That is, between handle and people's palm, be not prone to slip, thereby person taking exercise is comparatively comfortable.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the present invention is further described:

Fig. 1 is that the master of embodiments of the invention looks cutaway view.

In figure: 10, shell, 11, skid resistant course; 20, jackshaft; 30, spring housing; 40, spring; 50, handle.

The specific embodiment

Embodiment, as shown in Figure 1: power roller, comprises shell 10 and handle 50.Further say, in this shell 10, be articulated with jackshaft 20, on this jackshaft 20, non-rotatable cover has spring housing 30, and on this spring housing 30, cover has spring 40, and the two ends of this spring 40 are connected on this shell 10 and this spring housing 30.Meanwhile, this handle 50 is 2 and is individually fixed on the left and right end face of this jackshaft 20.Like this, be same as the using method of the power roller of prior art, person taking exercise takes kneeling position, and both hands grip respectively one handle 50, lies prone down forward, and the shell 10 of this power roller rolls forward, until person taking exercise lies prone, pours on ground.In this process, this jackshaft 20 can not rotate under the effect of this

handle

50, and 10 rotations of this shell, thereby this spring 40 gathers elastic potential energy, and then auxiliary exercise person reclaims power roller, finally returns to kneeling position.Because this power roller is without adopting compared with multi-part, thereby between parts, assembling is comparatively simple.Meanwhile, adopt spring 40 as gathering the critical piece that recovers energy, thereby this power roller have preferably restoring force.Certainly, the rotating direction of this shell 10 is unidirectional, that is, only can roll to the direction that this spring 40 is tightened up.Like this, between this shell 10 and this jackshaft 20, can be provided with and lock the device that projection (not shown on figure) or single direction ratchet (not shown on figure) etc. prevent these shell 10 reverse rotations.

Optimize:

This shell 10 is cydariform.That is, the mid diameter of this shell 10 is larger, and the diameter of the left and right sides is less.Like this, be convenient to these shell 10 straight lines and roll forward, also can be flexibly to left front, right front rolling.

The outside of this shell 10 is provided with skid resistant course 11, and this skid resistant course 11 can be rubber layer.Like this, make the rolling of this shell 10 there is elasticity.

This handle 50 is connected on the end face of this jackshaft 20.Such as, the end face of this jackshaft 20 is provided with protruding axle, this protruding axle is provided with spring stack, simultaneously, the inner side end of this handle 50 is provided with groove, and this recess sidewall is provided with positioning pit, thereby only needs this groove to be enclosed within on this protruding axle, and the end that makes this spring stack withstands in this positioning pit, can make this handle 50 be connected on the left and right end face of jackshaft 20.

This handle 50 bends downwards with respect to the axial line of this jackshaft 20.Such as, this handle 50 is reclinate arc or falls " √ " shape.Like this, this handle 50, under the effect of human bady gravitational, is difficult for rotating in company with this shell 10.

The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
