Abstract
The utility model provides a gravity walking-aid device which is jointly composed of a front driving system, a rear driving system, a front foot plate which is connected with the front driving system via a hinge, a rear foot plate which is connected with the rear driving system via a hinge and a driving wheel. Movable shaft overriding mechanisms are arranged in the front driving system and the rear driving system respectively. The changing of the gravitational potential of the human body when walking can be effectively utilized to realize fast walking by adopting the gravity walking-aid device.
Description
The utility model relates to a kind of running gear, particularly a kind of gravity walk helper that effectively utilizes human body gravitional force.
Have roller skate and a kind of manpower similar to the utility model drive footwear, the use of roller skate needs firmly pedal backward and could slide forward, and needs when taking a step lift with pin and take a step, and has increased burden on the pin, pretend for a kind of sports apparatus still can, then unsuitable as running gear; It is to reach the arc tooth plate that links to each other with bumper step by directive wheel support bumper step to drive the rotation of travelling gear driving driving wheel to overtake that manpower drives footwear, as a kind of running gear, is greatly improved than roller skate.But owing to do not surmount device, when bumper step lifted, arc tooth plate will drive the driving wheel counter-rotating, like this, and with overslaugh to overtake.In order to overcome it, must when lifting pedal, lift rear drive sprocket simultaneously, and this will repeat the weakness of roller skate.
The purpose of this utility model is to provide a kind of gravity walk helper, and it can change under the situation of human body walking custom hardly in the burden that does not increase human body, and the gravitional force that effectively utilizes human body reaches the purpose of walk help.
The purpose of this utility model realizes as follows: in order to demonstrate fully human body when walking, gravity is in the characteristics of forefoot, two cover drive systems before and after the utility model adopts, forefoot plate drives front-wheel to overtake by preceding tooth bar and train down, back sole drives trailing wheel by back tooth bar and train and moves ahead, back sole connects with back tooth bar and forefoot plate cylindrical hinge respectively, forefoot plate is divided into groove, roller is established on preceding tooth bar top, to form hinges, realize freely moving back and forth between forefoot plate and preceding tooth bar, one-way element is set respectively in the train of front and back, multiple spring is set respectively at the tooth bar position, human body is when walking like this, sole before and after alternately stepping, just can realize fast to overtake that the front and back sole is when lifting simultaneously, back-moving spring promotes forefoot plate and lifts, thereby solved the sense that drags that sole lifts, be described further below with reference to accompanying drawing:
Fig. 1 is the drive mechanism schematic diagram of this gravity walk helper.
Fig. 2 is the A-A view.
Contrast Fig. 1, with reference to Fig. 2, forefoot plate (1) connects with back sole (3) cylindrical hinge (4), back sole (3) connects with back tooth bar (5) cylindrical hinge (4), establish back-moving spring (6) in the tooth bar (5), the train of tooth bar (5) and gear (8) (9) compositions such as (10) realizes driving rear drive sprocket (7) jointly, forefoot plate is divided into slideway, built-in roller realizes that with preceding tooth bar (16) free hinge (17) connects, the train of preceding (16) and gear (11) (13) compositions such as (14) drives jointly establishes back-moving spring (15) in front driving wheel (12) tooth bar (16), when stepping under the current back sole (1) (3), to promote tooth bar (16) (5) respectively and move downward along slideway separately, train was rotated before and after tooth bar (16) (5) will drive respectively, and driving wheels (12) (7) rotate forward before and after driving, at this moment, gear (13) (9) is at the diagram solid line position.When pin upwards lifts, back-moving spring (15) (6) will move upward promoting tooth bar (16) (5) respectively respectively, at this moment, gear (14) (10) will drive free gear axle (13) (9) respectively and go to the diagram dotted line position, separate with gear (11) (8), slide forward thereby front and back driving wheel (12) (7) is able to freedom; When human body was upright, gear (11) (8) will promote gear shaft (13) (9) and go to the diagram dotted line position around gear (14) (10) axle respectively, thereby driving wheel (12) (7) was able to art skating before and after making under the drive of front and back driving wheel (12) (7).It is fixing with taking band also to be provided with pin on front and back two soles (1) (3), and during use, as long as bipod is separately fixed on the two walk helper soles, normal walking can realize sliding fast forward.
Remarkable advantage of the present utility model is the employing of train, so that gearratio Greatly improve, utilized fully gravity and the human body weight when walking of human body Power potential energy so that the speed of travel greatly improves, can be used as a kind of walking aid device Use.
Claims (3)
1. gravity walk helper, it is characterized in that: the built-in roller of forefoot plate (1) slideway (groove) and preceding tooth bar (16) constitute that free hinge connects and with head end be that the train and the front driving wheel (12) of tooth bar (16) transmission formed front drive system jointly, back sole (3) connects with back tooth bar (5) cylindrical hinge, and with head end be that the train and the rear drive sprocket (7) of tooth bar (5) transmission formed the rear drive system jointly.
2. by the described gravity walk helper of claim 1, it is characterized in that: be provided with back-moving spring (15), (6) in the forward and backward tooth bar, be provided with suitable slideway outward.
3. by claim 1 and 2 described gravity walk helpers, it is characterized in that: the front and back drive system is respectively arranged with free gear axle (13), (9) one-way element.
