Description
Technical field
Technology of the present invention relates generally to the bionical walk help walking stick of a kind of the elderly, is specially adapted to the bionical walk help walking stick of the elderly of mellow soil, belongs to the elderly's walk help utensil field.
Background technology
2010 the 6th time national census result shows; 60 years old and above population account for 13.26% of population, rise 2.93 percentage points than 2000, and 65 years old and above population account for 8.87% of population; Rose 1.91 percentage points than 2000, the aging process of China is progressively accelerated.Estimate that the population of China more than 60 years old in 2015 will account for 14% of population above 200,000,000, the population of the year two thousand fifty China more than 60 years old will account for 21% of population above 400,000,000.With advancing age, the elderly's locomotor activity can descend gradually.The assistive device that the elderly that it is inconvenient that walking stick is legs and feet uses when moving can improve the stability of standing and walking, and reduces the burden of shank, increases the speed of walking.
At present, less to the walk-aid equipment of mellow soil specially, the elderly can only adopt traditional walking stick usually when passing through mellow soil.Because the top layer of mellow soil is loose, bearing capacity difference and shear strength are low, when using traditional walking stick walk help, walking stick serious sagging and slippage occurs through regular meeting.So, traditional walking stick does not only help the elderly to play the effect of walk help, becomes a kind of burden on the contrary, and the walking that has increased the elderly is tired.If can change the geometry of walking stick and soil contact portion, ACTIVE CONTROL soil flow direction then can effectively utilize the bearing capacity of mellow soil, thereby improves the exercise performance of walking stick on mellow soil.
Ox often walks on mellow soil; With the long-term interaction of soil in; The sufficient hoof of ox has progressively formed good geometry through constantly evolving naturally, has on mellow soil that handling capacity is strong, the resistance of motion is little and characteristics such as the efficient height of taking action.Ox belongs to Artiodactyla, and the hoof palm is the lobe type, is divided into left and right sides two parts.The front end of the hoof palm is point slightly, and oblique the place ahead is suitable for burying, and when landing, makes the hoof palm surely drop on the soil, avoids sliding, and can produce bigger motive force; The rear end of the hoof palm is big slightly, and ovalize has oblique indent between the front and back end, and the soil that has limited the cow hoof below flows, and has played the effect of solid soil.When cow hoof buried, almost parallel with the soil face at the bottom of the hoof, hoof was less to the disturbance of soil, and near the soil the hoof flows slight.After cow hoof buries,, enlarged the contact area of cow hoof and soil, increased the frictional force of cow hoof and soil, can play stronger anti-skidding effect, improved driving power because the decline in cow hoof bulb is expanded.
Summary of the invention
Proposition of the present invention; Be intended in order to solve the problem that existing walking stick is not suitable in mellow soil, using; Utilize ox sufficient hoof structure and with the soil interaction relation; And the movement mechanism of ox on mellow soil, according to bionics principle, and a kind of bionical walk help walking stick of the elderly that is applicable to mellow soil is provided.
Technical solution of the present invention is real like this:
A kind of bionical walk help walking stick of the elderly that is applicable to mellow soil; Comprise rubber sleeve, handle, nipple, walking stick bar, regulate bolt, heighten cover, bottom girder, supporting leg, heighten hole, imitative cow hoof feet, pit cell cube, protecting film; It is characterized in that described rubber sleeve is contained on the handle, the lower end of handle is threaded with nipple in being welded on walking stick bar upper end; The hypomere of walking stick bar forms and to be slidingly matched with heightening cover, realizes walking stick bar lower rod section up and down flexible in heightening cover, is distributed with on the lower rod section of walking stick bar to supply the adjusting bolt to pass a plurality of holes of heightening of the differing heights of bar section; Heighten to be rotary with on the lateral surface of cover and regulate bolt and will regulate the bolt leading portion and insert the height of heightening in the hole with adjusting walking stick bar; Heighten and be uniformly distributed with four supporting legs of welding on the inferolateral surface circumference of cover, slightly point of front end is processed in the supporting leg bottom, oblique the place ahead, and the imitative cow hoof feet of rear end ovalize, the imitative cow hoof feet of four supporting legs is on same horizontal plane; Imitative cow hoof feet is the non-smooth surface that is the grid type regular distribution with pit type, oxidation of surperficial coating one deck or protective metal film; The imitative cow hoof of pit cell cube sidewall slopes inwardly, and circle or ellipse or square or rhombus are processed in the cross section of cell cube; The welding of two bottom girders intersections, its four end is welded on respectively on four supporting legs.
Compared with prior art, advantage of the present invention is conspicuous, mainly shows:
1, reasonable in design, compact conformation;
When 2, on mellow soil, moving, the supporting leg bottom surface reduces 62-84% to the adhesiveness of soil, and exercise performance improves 15-26%;
3, scalable walking stick height is to adapt to the elderly of different heights;
4, be easy to mounting or dismounting and take up space lessly, be easy to carry and store.
