Abstract

The utility model belongs to the field of sports movement apparatuses, and relates to an improved dumbbell, which can swing in three directions. The dumbbell consists of a grip shaft, support rings, support rods, springs, swinging mass blocks and the like, wherein each support ring is in a circle shape and is provided with three structures which are connected with the springs, each support ring is rigidly connected with the three support rods, one ends of the support rods are rigidly connected with each support ring, the other ends of the support rods are connected with one end of the grip shaft, one ends of the springs are connected with each support ring, the other ends of the springs are connected with each swinging mass block, each swinging mass block is connected with the three springs, and is also connected to each support ring through the springs, and each swinging mass block is provided with a metal tuning fork. Compared with the common dumbbell, the lifting of the common dumbbell mainly relies on the exercising of arms. When the dumbbell is lifted, the swinging in three directions is realized, the whole body exercises, the chest and abdominal part swings back and forth and exercises up and down, and the knee joints are also slightly changed, so the lifting of the dumbbell requires the coordinated exercising of the whole body.

Description

A kind of three-dimensional is rocked dumbbell

Technical field

The invention belongs to the sports movement apparatus field, relate to a kind of improved dumbbell, its function is that dumbbell can rock in three directions, in the time of training arm arm strength, can train the coordination ability of whole-body muscle.

Background technology

Modern people's health perception improves constantly, and like various body building, but many motions all is subjected to the restriction in time and space.Its small volume of dumbbell, the user must not take too large space when movement, and the motion that lifts the dumbbell is not subjected to spatio-temporal restriction, is a kind of to healthy useful motion very easily.

Lifting the dumbbell motion is by user's arm, to hold dumbbell to complete arm and bend, stretch or the motion of other general, can train muscle strength.But the motion that lifts the dumbbell also has its deficiency, and the motion that lifts the dumbbell is mainly strength building, and undertrained to neuromuscular harmony.In order to increase the function of training muscle coordination, need traditional dumbbell be improved.

The architectural feature of patent of invention 200810042366X " dumbbell with adjustable inertia resistance load characteristic " is the pendulum that there is rotatable bias dumbbell inside, the user is when up and down movement dumbbell, only have when firmly cycle and intensity and when suitable, just can make eccentric pendulum rotation.Strength during the dumbbell movement that do not have this structure and cycle be restriction not, and therefore less demanding to nervimuscular harmony in motion, during movement dumbbell of the present invention, cycle and the intensity of exerting oneself have requirement.After the rotation of the pendulum of the bias in dumbbell, produce periodic inertia force, this inertia force makes user's arm and whole body produce additional periodic vibration, for adapting to this periodic vibration, whole-body muscle produces periodic muscle tonue, and the muscle strength of whole body is also had to some training effects.

Above-mentioned its physical principle of dumbbell with adjustable inertia resistance load characteristic is to have stored mechanical energy in the moving process of eccentric rotation, when this dumbbell of movement, can have an inertia resistance.Along this thinking, can in dumbbell, utilize elastic energy storage, reach equally in motion process the situation that has inertia resistance, we have invented and have utilized elastic energy storage, during motion, reach the dumbbell that three-dimensional is rocked effect.

Summary of the invention

Structure of the present invention mainly is comprised of following components.

1. hold axle (1): holding axle (1) can be formed by metal or nonmetallic materials plastics or rubber processing, as by metal material processing, formed, hold axle (1) surface bag nonmetallic materials plastics or rubber, improve the sensation while holding axle (1).Holding axle (1) inner is solid construction or hollow-core construction, but the hollow-core construction weight reduction.

2. support ring (2): support ring (2) is by metal or nonmetal making.Be circular, three structures (6) that are connected with spring (4) are arranged on it.Support ring (2) rigid connecting is connected to three support bars (3).

3. support bar (3): it is upper that support bar (3) one ends are rigidly attached to support ring (2), and the other end is rigidly attached to an end of holding axle (1).

4. spring (4): it is upper that spring (4) one ends are connected to support ring (2), but the other end is connected on slosh mass piece (5).Spring (4) can be the spring that metal is processed into, and can be also the spring of macromolecular material processing.

5. but slosh mass piece (5): but slosh mass piece (5) as long as function have certain quality, its shape can be spherical, can be also cylindrical, triangle cylindricality etc.But slosh mass piece (5) is connected with three springs (4), then is connected to support ring (2) by spring (4).

But the slosh mass piece can be equipped with metallic tuning fork on (5), but when slosh mass piece (5) while rocking metallic tuning fork send the sound.

With common dumbbell, compare, the common dumbbell of movement is mainly arm motion, and the swing of chest belly is not obvious, and the chest belly is supreme lower motion almost.During movement dumbbell of the present invention, while holding, can do rocking of three directions, whole body all has motion, and the swing of chest belly also moves up and down, and knee joint also has small size variation, illustrates that movement the present invention needs the coordinated movement of various economic factors of whole body.

The accompanying drawing explanation

A kind of three-dimensional of Fig. 1 is rocked the dumbbell schematic diagram.

The specific embodiment

Embodiment 1.

By Fig. 1 machining 3 D, rock dumbbell, wherein holding axle (1) processes with metal, hold the axle surface one deck rubber is arranged, hold 250 millimeters of axial lengths, 250 millimeters of the diameters of support ring (2), but slosh mass piece (5) is the solid iron ball of 50 millimeters of diameters, spring (4) with elasticity as skin.

Embodiment 2.

By Fig. 1 machining 3 D, rock dumbbell, hold long 450 millimeters of axle (1), the axle (1) but both hands are shaken hands, all the other are identical with embodiment 1.

Embodiment 3.

By Fig. 1 machining 3 D, rock dumbbell, hold long 750 millimeters of axle (1), axle (1) can be put piggyback holding axle as barbell but both hands are shaken hands, and all the other are identical with embodiment 1.

Embodiment 4.

By Fig. 1 machining 3 D, rock dumbbell, hold long 750 millimeters of axle (1), piggyback, 600 millimeters of the diameters of support ring (2), slosh mass piece (5) are the solid iron ball of 100 millimeters of diameters to axle (1) but both hands are shaken hands.Being similar to barbell holds axle (1) and puts piggyback and rock in three directions.

Above-described embodiment is only in order to illustrate the present invention.The person that is familiar with the technique makes in the scope of spirit of the present invention various distortion, modification and application all should belong in category of the present invention.
