Abstract

The utility model provides a roller skate, which is a novel walking substituting tool. The utility model is composed of a front sliding guiding roller, two directional sliding rollers, a rear brake roller, etc. The utility model is characterized in that a speed reducing device and a brake device are arranged on the rollers, and the roller skate is safe to substitute walk. The utility model has the advantages of simple structure, portability and easy use, and the utility model is not only a portable walking substituting tool, but also a pair of toy shoes which is beneficial to health.

Description

Footwear voluntarily

The utility model relates to a kind of improvement of shoes, belongs to the footwear technical field.

Existing shoes can only be used for walking, can't slide, and the roller skate that uses on sports ground can only be used for the motion of roller skate, and it is just very dangerous to ride instead of walk with it.

Task of the present utility model provides a kind of light walking-replacing tool that has slip footwear wheels, slides on asphalt road or cement road with it, can equally go up a slope with bicycle, descending, and activity reaches the labour intensity that alleviates the people freely, the purpose of raising walking speed.

The technical solution adopted in the utility model is: front slide guiding footwear wheels (4) are single-wheels, are contained on the front-wheel support (3), and two directed slip footwear wheels (7) are contained on the impetus of sole center, and back brake footwear wheels (9) are contained on the middle rear wheel support (6).Respectively there is a brake connecting rod (12) back brake footwear wheel (9) both sides, axle center, the connecting rod front end has brake shoes (13), in axle center and support point of attachment both sides microscler sliding eye (11) oblique on is arranged respectively, the two ends, axle center respectively have one to draw semi-annular jade pendant (14) to constitute dead-man's device, brake footwear wheel are moved forward and backward and brake resets.Brake wheel strap (8) draws the circular slowing-down brake sheet (10) on semi-annular jade pendant (15) pinch wheels frame both sides to constitute automatic slow-down device with clamping plate.Directed flywheel in two directed slip footwear wheels (7) is made of the terraced tooth of interior circle (16), tongue semi-annular jade pendant card (18), both sides ball (17), Zhu Ding, pearl bowl (20), has and can only advance, and the characteristics that can not fall back have solved a difficult problem of going up a slope.Respectively there is an elongate slot at its positive two ends of girder steel (5) under the forward and backward foot pedal (1,2); A fixedly steel wire (22) is respectively arranged on the forward and backward foot pedal (1,2), can in elongate slot, move, in order to regulate the length of footwear.

Figure one is the footwear structure profile voluntarily.

Figure two is the footwear structure vertical view voluntarily.

Directed flywheel schematic diagram in the figure three directed slip footwear wheels.

Below in conjunction with accompanying drawing the utility model is further described:

Below the foot pedal (1,2) girder steel (5) that can regulate length is arranged before and after the footwear voluntarily, respectively there is an elongate slot at its positive two ends; Respectively have on the foot pedal one fixedly steel wire (22) can in elongate slot, move, in order to regulate the length of footwear.Front slide guiding footwear wheels (4) are single-wheels, are made of rubber wheel (23) and ball bearing (24), are contained on the front-wheel support (3), play the guiding rotary action.Two directed slip footwear wheels (7) are made up of directed flywheel and rubber wheel, and its axle center is fixed on the square block rubber (27) that respectively a spill iron plate (25) is wrapped in up and down, by rod bolt (26) and oval hole, play shockproof and prevent to swing effect.Two directed slip footwear wheels are contained on the impetus of sole center, during walking, gravity center of human body's balance can be pushed ahead, when needing to slow down, as long as the gravity center of human body slightly backward, rear braking wheel (9) is landed (the leading wheel to the slip footwear lifted up), and the brake block (10) on rear braking wheel wheel frame both sides is subjected to the strap two ends to draw the semi-annular jade pendant effect to produce certain frictional force, and vehicle wheel rotational speed is slowed down.As halting, the gravity center of human body transfers on the back brake footwear wheels (9), footwear wheels is produced on the ground frustrate power after bigger, add that sliding eye (11) upward tiltedly, under the effect of inertia towing tension, brake wheel and axle center can be passed the 1-1.5 centimetre automatically backward, brake block and brake wheel frame generation this moment rubs and slows down, meanwhile, the brake connecting rod (12) at brake footwear wheel shaft two ends will affect two brake shoes (13) tightly to be pressed on two directed movable pulleies, prevent it to rotate, thereby reach the purpose that halts.In the time will moving on, the gravity center of human body transfers to two directed movable pulley front portions, and front slide guiding footwear wheels (4) land, and back brake footwear wheels (9) have been lifted up, and (lift up time-out when rear braking wheel, draw semi-annular jade pendant can make rear braking wheel recover the normal position) just can move on.

Originally footwear have only been done a little adjustment at the footwear wheel voluntarily, and have set up deceleration, brake gear.This voluntarily footwear the repertoire of roller skate is arranged, stronger than roller skate conformability again, the descending that can go up a slope, brake is flexibly, and is safe and reliable, has and rides instead of walk, exercise, the multiple function of amusement.

Claims

1. footwear voluntarily, it is made up of girder steel, front slide guiding footwear wheel, directed slip footwear wheel, the back brake footwear wheel of foot pedal, adjustable shoes length, it is characterized in that:

(1) front slide guiding footwear wheels (4) are single-wheels, are contained on the front-wheel support (3), and two directed slip footwear wheels (7) are contained on the impetus of sole center, and back brake footwear wheels (9) are contained on the middle rear wheel support (6);

(2) back brake footwear wheel (9) both sides, axle center respectively have a brake connecting rod (12) connecting rod front end that brake shoes (13) is arranged, in axle center and support point of attachment both sides microscler sliding eye (11) oblique on is arranged respectively, the two ends, axle center respectively have one to draw semi-annular jade pendant (14) to constitute dead-man's device, and brake wheel strap (8) draws the circular slowing-down brake sheet (10) on semi-annular jade pendant (15) pinch wheels frame both sides to constitute automatic slow-down device with clamping plate.

2. footwear voluntarily according to claim 1 is characterized in that: the directed flywheel in two directed slip footwear wheels (7) is made of the terraced tooth of interior circle (16), tongue semi-annular jade pendant card (18), both sides ball (17), Zhu Ding, pearl bowl (20).
