Abstract
The utility model discloses a pair of two-roller skating shoes. Each shoe bottom is provided with a front shaft frame and a back shaft frame, and the front shaft frame and the back shaft frame are respectively provided with a front shaft and a back shaft. The front shaft and the back shaft are respectively provided with the roller whose surface is arc and rolling bearings matched with the roller. The roller accords to the relational expression: 1.2BE<=MN<=1.5BE3/5< ST< 4/5BE, and the intersection point of the extension line on the outer edge of the arc roller surface of the roller is positioned on the shaft axis of the roller. (The BE is the maximum outer diameter of the roller, the MN is the length of the roller, and the ST is the outer diameter of the roller end face). The utility model has the advantages of labor saving for move and portable and flexible slide, and the balance is easy to control and shoe knifes can be pressed.
Description
The utility model belongs to a kind of sports apparatus, particularly a kind of two-wheel ice skate.
Roller skating is a kind of very universal sports and amusement campaign, and traditional roller skate is to be made of footwear plate and fastening shoestring, the support and rack-mount two row (four) the roller wheels that are installed on the footwear plate, and its advantage is to stand steadily, economizes ankle power; But when it slides, can not push type broach, underaction.In recent years, a kind of novel roller skate has appearred, it is three of being positioned on the straight line to be installed on the support that is fastened on the footwear plate or four roller wheels form, though this kind roller skate has the energy push type broach, slides flexible, light and handy advantage, but need bigger ankle power when standing, thereby effort and the difficult balance of grasping.
The purpose of this utility model is to overcome the deficiencies in the prior art part, a kind of easy grasp balance is provided, slides steadily, but economize ankle power and push type broach, slide light and handy two-wheel ice skate flexibly.
The utility model is achieved in that it has a sole, shoestring is installed on sole, pedestal before and after it also is equipped with on sole, on forward and backward pedestal, be separately installed with front axle, rear axle, being separately installed with wheel face on forward and backward axle is circular-arc roller wheel and the rolling bearing that is mated, and said roller wheel satisfies following relational expression:
1.2BE≤MN≤1.5BE
3/5<ST<4/5BE
And the joining of the extended line of the circular-arc wheel face outer rim of roller wheel is positioned on the axial line of roller wheel.
In the formula: BE is the maximum outside diameter of roller wheel, and MN is the length of roller wheel, and ST is roller wheel end face external diameter.
This skating shoe advantage is province's ankle power, grasps balance easily and light and flexible when sliding, when turning and side can push type broach when pedaling, and just like the sensation of skating, and these ice skate are simple in structure, cost is low, and is practical.
The drawing explanation:
Fig. 1 is the skating shoe structural representation of this two-wheel;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is second kind of structural representation of roller wheel;
Fig. 4 is the third structural representation of roller wheel.
Provide embodiment of the present utility model below in conjunction with accompanying drawing:
Embodiment 1:
Shown in accompanying drawing 1,2, the sole 2 that these ice skate have a hard material to make, (said footwear plate 2 also can be formed by two plate butt joints, so that adjust footwear plate length).Fastening shoestring 1 is installed on sole 2, on sole 2, forward and backward pedestal 3 is installed by screw and packing ring, on forward and backward pedestal 3, forward and backward axle 6 is installed by nuts and washers, be separately installed with by the forward and backward roller wheel 5 of steel (or iron or duroplasts make), bearing 4 and the dust cap 9 that is mated by sleeve 7 and packing ring 8 on forward and backward axle 6, said roller wheel satisfies following relation:
1.2BE≤MN≤1.5BE
0.6BE<ST<0.8BE
In the formula: the maximum outside diameter of BE-roller wheel
The length of MN-roller wheel
The end face external diameter of ST-roller wheel
And the joining of the extended line of roller wheel wheel face outer rim is positioned on the axial line of roller wheel.
Learn by experiment, optional MN=BE+3/10BE, ST=7/10BE can keep balance again during with the assurance push type broach flexibly best.
Embodiment 2:
The wheel face of this skating shoe roller wheel 5 is processed or is made " V " type groove 5A, is processed into blunt sword between two adjacent slot 5A, and other is with embodiment 1.
Embodiment 3:
The wheel face of this skating shoe roller wheel 5 is made screw-like " V " type groove 5a, by screw adhesive tape 5b is installed in groove, and to play damping effect, other is with embodiment 1.
In the above-described embodiments, also middle pedestal can be installed on this skating shoe base plate, axis and roller wheel and bearing are installed on middle pedestal, its structure is the same.
Claims (3)
1, a kind of two-wheel ice skate, comprise sole and the shoestring that is installed on the sole, it is characterized in that, pedestal (3) before and after on sole (2), being equipped with, on forward and backward pedestal (3), be separately installed with front axle, rear axle (6), being separately installed with wheel face on forward and backward axle (6) is circular-arc roller wheel (5) and rolling bearing (4) that is mated and dust cap (9), and said roller wheel satisfies following relational expression:
1.2BE≤MN≤1.5BE
3/5<ST<4/5BE
And the joining of the extended line of the circular-arc wheel face outer rim of roller wheel is positioned on the axial line of roller wheel.
According to the said two-wheel ice skate of claim 1, it is characterized in that 2, the wheel face of said roller wheel (5) is processed with or makes " V " type groove (5A), is processed into blunt sword between two adjacent slots (5A).
According to the said two-wheel ice skate of claim 1, it is characterized in that 3, the wheel face of said roller wheel (5) is processed with screw-like " V " type groove (5a), and adhesive tape (5b) is installed in groove (5a).
