Embodiment 1

[0040] Example 1. See the present embodiment heel two-wheeled roller skates Figure 1-2 , with a shoe body 1 and a fixed bracket 2, a groove 4 is provided on the heel of the sole 3, and the fixed bracket 2 is fixedly connected with two groups of shoe wheels 5, 6 (that is, the shoe wheel shaft is fixed on the fixed bracket, and the shoe wheel passes through the bearing. 6 parts of the rear shoe wheel are exposed outside the rear side of the heel, and the arc of the rear side of the heel can also be increased, so that the contact point of the outer wheel of the partially exposed rear shoe wheel is basically parallel to the sole surface; front and rear The axis line of the shoe wheel and the horizontal line (or sole plane) are arranged at an oblique angle of 5-30 degrees (that is, α = 5-30°), and the best inclination angle is 8-18 degrees (Note: the axis of the front and rear shoe wheels The oblique angle α between the center line and the horizontal line is also the intersection...

Embodiment 2

[0042] Example 2. This embodiment is shown in Fig. 5-6, has shoe body 1, fixed support 2, groove 4; Different from embodiment 1, shoe rear wheel 6 is fully exposed outside the rear side of the heel through connecting rod 67. Wherein, the connecting link 67 in Fig. 5 is fixedly connected on the fixed bracket or the heel of the shoe; while the connecting link 67 in Fig. 6 is movably connected on the front shoe wheel shaft, and is also movably connected with a belt guide groove above the fixed bracket. The support arm 69 of 68, the left and right connecting rods 67 are fixedly connected with a positioning pin 70, the positioning pin 70 penetrates in the guide groove 68 and can slide along the guide groove, and a backrest is connected between the support arm 69 and the fixed bracket 2 Bit spring 71, front shoe wheel 5 parts are exposed, and its bottom is substantially parallel with sole, namely same on the same plane. In Fig. 5-6, the line connecting the axes of the front and rea...

Embodiment 3

[0043] Example 3. This embodiment is shown in Figures 7-8, it has the same structure as Embodiment 1, the difference is that the rearward extension 8 of the fixing bracket 2 of this embodiment is fixedly connected with a brake member 9.

Abstract

The roller skate with two wheels in the heel has the main structural characteristic that there are two longitudinally arranged wheels fixed to the rack in the heel. The axle line of the two wheels is in one angle of 5-30 deg to horizontal line. There are braking mechanism and other members behind the rack. The present invention has the sliding function the same as that of single-wheel skate as well as excellent stability and safety.

Description

Technical field [0001] The invention relates to a roller skate with a shoe wheel on the heel and belongs to the technical field of roller skates. Background technique [0002] In the prior art, there is a roller skate with a single-wheel shoe on the heel. Due to the single-wheel structure, the stability of this shoe is poor when in use. After falling, the danger is greater. Contents of the invention [0003] In view of the above situation, the present invention is to provide a roller skate with two sets of front and rear wheels on the heel, which can not only keep the gliding pleasure of the unicycle, but also be more stable and safe than the current unicycle. [0004] The technical solution adopted by the present invention to solve the technical problem is that the present invention has a shoe body (1) and a fixed support (2) mounted on the heel of the sole, and two groups of shoe wheels (5) arranged in front and rear are connected on the fixed support. , 6), the line c...
