CN2629760Y - Crank type dumbbell structure - Google Patents

Abstract

A crank dumbbell structure comprises a holding rod and two weighting blocks connected at two ends of the holding rod, wherein bends with pre-defined angles are separately formed where the holding rod is near to the two weighting blocks and an axle centre of the two weighting blocks presents parallel deviation at proper distance. The utility model increases comfort of griping by maintaining S-type inclined crank state of the holding rod and is not apt to slipping when held vertically for raising or swing so as to improve safety of arm exercises.

Description

Crank-type dumbbell structure

Technical field

The utility model relates to a kind of dumbbell structure, especially a kind of holding rod is corresponding bending, and the two ends loading piece of this dumbbell forms the parallel offset of a suitable distance, can increase the comfort of gripping, guarantees to grip the crank-type dumbbell structure of safety and stability in lifting or the swing process simultaneously.

Background technology

See also shown in Figure 1, dumbbell 10 is a kind of arm muscular training body-building apparatus commonly used, and mainly by a holding rod 11, its two end respectively is connected with a loading piece 12, it is made that its all members are closely knit metal material usually, so integral body has certain weight, when using operation, only need directly to grip this holding rod 11 ends with palm, can carry out various arms swings or the action of lifting up and down, and,, reach the function of physical exercise simultaneously to increase the endurance of arm muscle by the weight of dumbbell 10.

The use of known dumbbell 10 is existing for many years, and is a kind of lightweight arm exercises equipment that is difficult to replace, but it still has following defective:

1, because the holding rod 11 of this dumbbell 10 and the axle center of two end loading pieces 12 are being connected with of a straight line, so when palm grips dumbbell 10 actions, the weight of this dumbbell 10 self will force the A of wrist joint portion to produce one and reverse, make palm and arm form a stressed naturally deflection angle, but this twisting resistance will can't meet the angle that the human body palm grips on the dumbbell 10 because of straight line holding rod 11, will cause the more or less doubt of athletic injury of user, as shown in Figure 2.

2, because the holding rod 11 of known dumbbell 10 and two end loading pieces 12 are adopted straight line is connected with, and there is not any prominent setting position device therebetween, so when dumbbell 10 be vertically to lifting up and down or during wobbling action, its holding rod 11 very easily produces the phenomenon of slippage with palm, as shown in Figure 3.

3, this known dumbbell 10 is positioned on the axle center of level at two loading pieces 12 under same size, the weight, no matter gripping holding rod 11, it how to change the friendship direction, its loading piece 12 is same horizontal direction, so known dumbbell 10 lacks the motor pattern that other tempers the arm muscular endurance.

4, because the use of known dumbbell 10 more than the row year, the moulded style and features of all stagnating in former straight line lacks popular conversion trend in the structure field, so moulded more dull.

In view of this design people is to rely on for a long time for the research of various dumbbell structures and the design of digesting, and creates a kind of crank-type dumbbell structure.

Summary of the invention

Technical problem to be solved in the utility model is, make the dumbbell holding rod more meet the angle that the human body palm grips, it establishes the kink of a predetermined angular respectively at the holding rod two ends loading piece place of dumbbell, make the two ends loading piece of this dumbbell form the parallel offset of suitable distance, make holding rod just can be " S " tilting crank state.

The technical solution of the utility model is, a kind of crank-type dumbbell structure respectively is connected with a loading piece by a holding rod two ends and is formed, wherein,

The nearly two end loading piece pre-positions of this holding rod are formed with the kink of a predetermined angular respectively, and the axle center of two loading pieces is the parallel offset setting.

The interior angle of described kink is 140-145 ° a bending angle.

Characteristics of the present utility model and advantage are as follows:

1, meets the gripping of ergonomics, because its holding rod of dumbbell of the present utility model is the tilting crank state of suitable angle, so two loading pieces are the horizontal-shift of non-concentric, helping palm directly stretches through and grips this holding rod, and wrist joint need not to impose an extra windup-degree, so can avoid reversing of wrist joint injured.

2, prevent to descend vertically upward lifting or swing start process to produce slippage, because holding rod of the present utility model both ends have two kinks, the support that can be beneficial to palm grips the location, mat two loading pieces are the offset design of non-concentric simultaneously, can make palm descend the gripping of lifting or wobbling action more stable vertically upward, and be difficult for producing slip phenomenon.

3, the convertible multirow motor pattern that is, the utility model is because two loading pieces are the skew of non-concentric, when changing holding rod gripping direction, about its loading piece then can be thereupon or deflection up and down, the user can cooperate behavior pattern to give reversing of wrist joint portion, to obtain the motor pattern of a splendid gripping.

4, structure has novelty, and the utility model removes and can make the above-mentioned function of dumbbell generation by this corresponding kink crank, more makes dumbbell have the style of new style.

The specific embodiment

At first, see also shown in Fig. 4,5, crank-type dumbbell 20 of the present utility model respectively is provided with loading piece 22 by two ends of a holding rod 21 and is constituted, and this structure is roughly with known identical, wherein:

Holding rod 21 nearly loading pieces 22 pre-positions of this dumbbell 20, the corresponding respectively kink 211 that is formed with a predetermined angle makes two loading pieces 22 form the non-axis parallel skew of a suitable distance.

Wherein, the interior angle of this kink is 140-145 ° a bending angle.

Enforcement action of the present utility model is as follows with the effect that can reach.

Please cooperate shown in Figure 6, the utility model respectively forms a kink 211 in holding rod 21 2 sides of dumbbell 20, integral body is meet the crank-like structure of ergonomic designs, when palm grips dumbbell 20 actions, the weight of this dumbbell 20 self makes integral body be an included angle, this moment, the user palm can be via the crank of the curved arc of holding rod 21, change and meet the angle that human body grips, and be the horizontal-shift design of non-concentric because of loading piece 22, so the user can grip the hobby of angle because of the individual, and reaches the purpose of comfortable grip.

Please cooperate shown in Figure 7, when the utility model dumbbell 20 with vertically when gripping and carry out lifting up and down or swinging arm, because these holding rod 21 2 sides have kink 211, so can form the positioning auxiliary device of this gripping palm, the while two loading piece 22 non-collinear offset design that form, it is more stable that swing is gripped, and be difficult for slip phenomenon takes place, and makes integrated operation more steady and smooth and safety.

Crank-type dumbbell structure of the present utility model, a kind of holding rod that is corresponding bending crank that has is provided, and the loading piece at two ends forms the parallel offset of a suitable distance, can increase the comfort of gripping, guarantee simultaneously to grip in lifting up and down or the swing process, have the crank-type dumbbell structure of security and stability.

The above is a specific embodiment of the utility model only, is not in order to limit the utility model, to this area those of ordinary skill, and the various variations of being done, only these change example, all should be included within design of the present utility model and the protection domain.

Claims (2)

1, a kind of crank-type dumbbell structure respectively is connected with a loading piece by a holding rod two ends and is formed, and it is characterized in that:

The nearly two end loading piece pre-positions of this holding rod are formed with the kink of a predetermined angular respectively, and the axle center of two loading pieces is the parallel offset setting.
