Abstract

The present invention relates to a roller skate having two wheels (4) in the transverse direction in the frame (2) and the wheel shaft (12) attached to the bottom of the sole of the sole of a light shoe or integral boots (15) normally worn.

The roller skates thus constructed can produce agile and various movements, and have a low ground height (11) to maintain stability and at the same time maintain three contacts on the ground with only simple ankle movements. No skilled skills are required, so even beginners can enjoy it immediately. It also provides the function of walking aid. It can be easily walked when worn on stairs or slopes, and can be detached and easy to carry.

Description

Roller skates

The present invention was devised for the purpose of making roller skates safer, more convenient and useful in daily life.

Specifically, the two wheels 4 are applied in the horizontal direction with respect to the frame 2 so that the wearer can independently rotate the roller skates 180 degrees or more while the roller skates are stopped at the left and right positions, and the wearer can be rotated in the center axis. It can be rotated 360 ° without rolling motion to produce various movements and U-turn in a straight line while driving.

In addition, by lowering the ground height (11) to maintain a sense of stability and at the same time with only a slight ankle movement, the driving traction and braking force can be taken in the same state of normal pace by maintaining the three contacts on the ground as the front heel (10) and the two wheels (4). Because it is not dangerous and requires no skilled skills, even beginners can enjoy it immediately and can easily walk on stairs, slopes, and uneven roads with a light heel, so you can easily ride a bus or subway while wearing it. .

The present invention can take the driving propulsion and braking force in a straight line in an upright walking state without any difficulty, and provides a convenient driving function as a walking aid when walking at a short distance or a long distance because stable driving is achieved. Its simple components make it easy to carry, easy to wear, easy to carry on, and easy to carry.

Normal skates and inline skates are relatively lacking in stability due to the high ground clearance, and because of the rolling motions of the rolling motions, they are often injured, heavy and clunky, difficult to carry, expensive, and incompatible with walking shoes. Many prior arts have been developed and commercialized to solve these shortcomings, but there are many difficulties in accepting practicality, durability, structural complexity, ease of manufacture, and the like.

Therefore, the present invention is to solve the general problems as described above can be equipped with two wheels (4) in the transverse direction with respect to the frame (2) to produce a variety of motions and the wheel axle (12) close to the shoe sole (1) By lowering the ground height (11) to increase stability, you can enjoy driving safely and comfortably. It is easily detachable and compatible with walking shoes. It is easy to carry and walks with only a heel without any assistance. It provides the function as a walking aid and at the same time as for sports, and because of the simplicity of components, the failure rate and manufacturing cost are also low, thus solving the problems and disadvantages of the prior art and at the same time providing the functions that cannot be taken in the prior art. There is this.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 to 2 is an embodiment of the present invention, the wheel bracket and tightening band bracket 6 is integrally provided as shown in Figure 4 in the frame 2 installed on the bottom of the shoe sole (1). The wheel shaft 12 is mounted in the wheel shaft hole 13 in Fig. 5A in the transverse direction with respect to the frame 2, and the wheels 4 are mounted at both ends. Since the wheel shaft hole 13 is located close to the frame 2, the ground clearance 11 is lowered. Wheel bracket and tightening band bracket (6) in addition to its unique functions to protect the wearer's left and right side of the wheel from the wheel (4) and also to prevent the left and right push at the same time. It is provided with a rear anti-tuck jaw and the wheel shaft cover (3) to prevent the roll back of the roller skate when driving straight and left and right anti-trail (8) to prevent the left and right push when left and right or 360 ° rotation. The anti-rolling jaw and the wheel shaft cover 3 also serve as a cover function to prevent the shoe sole 1 from touching the wheel shaft 12. A normal tightening band (7), a tightening band fastening hole (9), and a normal brake (5) for attaching and detaching are provided.

The front heel 10 off the tip of the frame 2 maintains three contacts on the ground together with the two wheels 4 in a stationary state as shown in FIG. 3 and uses the front heel 10 during driving. Kick back to gain momentum. This operation is the same as the operation during walking. Therefore, in both slow and high speed driving, the upright driving and the straight driving are performed while the wearer is comfortable.

Meanwhile, as shown in FIG. 5B, the wheel shaft hole 13 may be positioned at the lower end of the frame 2 to adjust the ground clearance 11 when the wheel of the small size is mounted.

6 is another embodiment of the present invention,

Integral boots 15 can be installed to increase the firmness and the scratch pad 14 can be attached to the same driving propulsion and driving method as the embodiment of the present invention can be obtained.

As described above, according to the present invention, it is possible to produce a motion that can not be taken in ordinary skates or inline skates, and the driving is performed in a safe and comfortable state, and it is compatible with walking shoes, and is easily removable and easy to carry.

In addition, due to the simple and simple components, the failure rate is low, the manufacturing cost is low, the wearing comfort is good, and it has the convenience as a walking aid for the long-term walking of the elderly or the child.
