Abstract

The utility model relates to a hand exerciser used for the hand support at the time of crawling movement in order to simulate four-foot crawl of human ancestors, belonging to an athletic apparatus. The exercise is kept for a long time; the negative-pressure of the thoracic cavity and the abdominal cavity can be reduced; the burden of heart can be reduced; the stress of cervical vertebra spine can be improved. The utility model has the efficiency of disease removing and body building. A multiway rotary touchdown component, a cuff component which is convenient for arms to hold and a connecting rod component which is used for connecting the two parts are combined into a touchdown supporting device which can move following the arms. The utility model can be used for opening up a new project for sports and body building.

Description

Hand exerciser

The utility model belongs to a kind of body-building apparatus, can be used as simultaneously walks upright have any problem people's walk help instrument, the support of contacting to earth of hand when special use comes crawling exercises.

Creeping is human ancestors' a kind of main walking manner.And the human body self structure, as creeping from the mechanics angle analysis is preferably.Therefore the human evolution is after walk upright, and under erectility, owing to self body weight power effect, some position of health is in disadvantageous stress.Increase as thoracic cavity and abdominal cavity negative pressure, over-burden for heart, and cervical vertebra, each joint of backbone are in gravity pressure and compel state.Human actual life is very far away apart from theory analysis level limit.Numerous disease is hard to guard against, and it not is irrelevant therewith tracing it to its cause.Therefore, if the modern can often carry out crawling movement consciously, exercise is walking on all fours, and is inevitable healthy, can play result of treatment that medicine is beyond one's reach to some disease.For some difficult and complicated illness, may obtain beyond thought effect especially.But human present body characteristics is not easy to crawling movement, and the relative short legs of arm is a lot.Certain difficulty is arranged when crawling exercises.

The purpose of this utility model is to provide a kind of and prolongs that arm uses, and the hand of being convenient to crawling exercises is lifted up.

At first it must have one can be so that grip, the wrister assembly that moves with arm; An assembly that contacts to earth that can multidirectional rotation reliably contacts with ground also must be arranged; Also must there be the arm length that to extend that the link assembly of cushioning effect is arranged.

Fig. 1 is the utility model example structure schematic diagram;

Fig. 2 is that Figure 1B-B is to cutaway view;

Fig. 3 is a wrister components side view after handle upwards rotates 180 ° among Fig. 1.

The assembly that contacts to earth among Fig. 1 is formed rubber blanket 1 and the pad 2 that simple universal saved and be fixed on recessed 4 flange surface by recessed 4, projection head 5, pad 3 and is formed.For rubber blanket 1 all can well be contacted in different angles with ground, a turriform balance spring 6 is housed.Balance spring 6 is fixed in the pad fastening bolt between bolt hole extension and recessed 4 external annulus.Topmost portion is the wrister assembly, be to be main stress spare with a U type support 12, a hard guard ring 15 that can stretch into arm is fixed in its upper end, and the centre is adorned near the soft protecting band 13, protecting band and to be adorned a semi-ring wrist that is rigidly attached on the U type support apart from the outside that wrist goes up the position slightly and keep off 14.The handle 9 at the 180 ° of angles of can upwards overturning is equipped with in below, U type frame bottom surface.U type frame hand rest position is covered with soft pad.Connect above-mentioned two assemblies, what the arm that is used for extending was used is a link assembly.Be to form by interior pipe 7, outer tube 8 suits.There is the section of dilating interior pipe 7 upper ends, and outer tube 8 lower end endoporus have a contraction section, crimping buffer spring 10 behind the interior pipe insertion outer tube.Outer tube flange surface and U type frame 12 bottom surfaces are fastenedly connected.Pipe 7 was an one through bolting in protruding head rod 5 staight shank ends inserted.

People's arm stretches into from guard ring 15, pass protecting band 13, palm is held U type frame bottom, wrist retaining 14 just in time is positioned at the forearm outside, and wrist retaining and protecting band are in each side of arm and assist wrist body support of exerting oneself, as feel inconvenient, handle 9 can also be rolled up, the back of the hand supports U type frame lower curtate, and finger outwards rolls up, and holds handle 9.Hand is lifted up with arm and is connected as a single entity, and can swing alternating movement with arm, forms the good comfortable posture of creeping.

This device can overcome the short inconvenience of the human upper limb difficulty of creeping.Arm is stressed rationally.Simple in structure, be convenient to make.Not only can be used as and carry out the exercise of creeping and taking exercise, and can truly have disabled person's walk help instrument of difficulty as walking upright.

Claims
