Abstract

The utility model relates to deadweight driving roller skates, wherein, a forefoot wheel is fixed at the front end of the bottom of the footboard; a post foot wheel is fixed with a post foot wheel shaft; one end of a moveable bracket is hinged with the post foot wheel shaft and the other end is hinged with the footboard; a spring is fixed between the moveable bracket and the footboard, a one-way driving wheel and a rack are fixed by the post foot wheel shaft; a gear meshed with the rack is fixed with the footboard by a bearing; a post large driving wheel is fixed on the same shaft with the gear; a fore small driving wheel meshed with the post large driving wheel is fixed with the footboard by the bearing; a fore large driving wheel is fixed on the same shaft with the fore small driving wheel; the fore large driving wheel is meshed with the one-way driving wheel. The utility model moves forward by the personnel gravity and then saves labour.

Description

Deadweight driving dry skate

(1), technical field

The utility model relates to a kind of Deadweight driving dry skate.

(2), background technology

At present the roller skate that uses has just been installed several runners under sole, and motion is to pedal ground by the people to oblique rear, utilizes reaction force forward to move, and human body low from the gravity utilization rate is so relatively require great effort.

(3), summary of the invention

In order to overcome the shortcoming of prior art, the utility model provides a kind of Deadweight driving dry skate, and it only utilizes travelling forward from gravity of human body, so very laborsaving.

The technical scheme in the invention for solving the technical problem is: front truckle is fixed on the front end of pedal bottom surface, rear truckle and rear foot wheel shaft are fixed, one end and the rear foot wheel shaft of travel(l)ing rest are hinged, the other end and pedal are hinged, fixing spring between travel(l)ing rest and the pedal, fixing unidirectional drive of rear foot wheel shaft and tooth bar, fix by bearing and pedal with the tooth bar meshed gears, with the coaxial fixing back of gear large drive wheel, fix by bearing and pedal with the preceding little drive of back large drive wheel engagement, with the coaxial fixing preceding large drive wheel of preceding little drive, preceding large drive wheel and described unidirectional drive engagement.

With the gear place that is engaged with clamping block is housed at described tooth bar, tooth bar and the gear that is engaged with locking can be able to be made existing roller skate and used.

Owing to only utilize travelling forward of human body, so very laborsaving from gravity.Volume is little, and is in light weight, and assembling is easy to carry easily.Because tooth bar and the gear lockable that is engaged with, so really realized amusement, be healthy and strong, manned perfect adaptation.

(4), description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model structural representation front view;

Fig. 2 is the utility model structural representation vertical view;

Fig. 3 is the utility model structural representation right view.

(5), the specific embodiment

Front truckle 2 is fixed on the front end of pedal 1 bottom surface, as shown in Figure 1.Rear truckle 10 is fixing with rear foot wheel shaft 5, as shown in Figure 3.One end and the rear foot wheel shaft 5 of travel(l)ing rest 13 are hinged, and the other end and pedal 1 are hinged, fixing spring 4 between travel(l)ing rest 13 and the pedal 1.Fixing unidirectional drive 11 of rear foot wheel shaft 5 and tooth bars 9 have baffle plate at the end of tooth bar 9.Fixing with tooth bar 9 meshed gears 7 by bearing and pedal 1, with gear 7 coaxial fixing back large drive wheels 6, fixing with the preceding brief biography driving wheel 3 of back large drive wheel 6 engagements by bearing and pedal 1, with preceding brief biography driving wheel 3 coaxial fixing preceding large drive wheels 15, preceding large drive wheel 15 and described unidirectional drive 11 engagements, as shown in Figure 2.With gear 7 places that are engaged with clamping block 12 is housed at described tooth bar 9, tooth bar 9 and the gear that is engaged with 7 lockings can be able to be made existing roller skate and used.Rear truckle 10 is unlikely runs into pedal 1, fixed stop 14 on pedal 1 bottom surface of travel(l)ing rest 13 movement locus in order to make.

Open clamping block 12 during use, the user lifts a pin, pedal 1 on the another pin is subjected to the effect of whole body gravity, begin to move down, brief biography driving wheel 3, preceding large drive wheel 15, unidirectional drive 11, rear foot wheel shaft 5 and rear truckle 10 before tooth bar 9 handsetting gears 7, gear 7 drive successively by back large drive wheel 6, thus the people is travelled forward, lift the another pin then and travel forward, so repeat to get final product.

Claims
