Abstract

PURPOSE:To constitute the roller skates so that a user can stop easily by putting down only the heel in an unfamiliar initial stage, can slide and stand still without anxiety as he likes, and can execute training joyfully by protruding downward a little a middle roller against a roller and a rear roller, and also, interposing a brake member between the rear roller and a pair of legs. CONSTITUTION:A roller skate for a beginner is inclined forward a little, and when a front roller 5a and a middle roller 5c are put on the floor and a rear roller 5b is floated, an advance or a retreat can be executed. When it is desired to stop in the course of sliding, when the weight is put onto the heel, the front roller 5a is floated, the rear roller 5b and the middle roller 5c are put on the floor, and the rear roller 5b comes to scarcely rotate by a brake member 7, therefore, it is possible to stop easily, and also, it is possible to stand still without anxiety. In such a way, in an unfamiliar initial stage, when the weight is put onto the heel any time in accordance with necessity, the front roller 5a is floated, the rear roller 5b and the middle roller 5c are put on the floor, and it is possible to stop easily.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to roller skates for beginners that allow even beginners to stand stably.

<Conventional technology> This will be explained with reference to FIG. 6, FIG. 6, and FIG.

Conventionally used roller skates for beginners are constructed as follows. In other words, a sole plate on which to place feet wearing shoes.
The length can be adjusted via a slide rail 2 that connects the IN bottom plates la and lb, which are divided into front and rear parts. Leg pairs 3a and 3 are provided on the front and rear of the bottom plate 1a and lb, respectively.
b provided, a horizontal cylindrical body 9a between the left and right of each leg pair 3a, 3b,
9b, and pass the roller shafts 4a and 4b through the centers of the horizontal cylindrical bodies 9a and 9b, respectively, to form the roller shafts 4&.

A front roller 5a and a rear roller 5b are provided at both ends of the roller 4b, respectively.
is supported by a shaft. In addition, a truncated cone-shaped stopper 6 is attached to the lower surface of the front end of the front sole plate 1a in a forward downward direction, and a foot fastening member 11 for fixing the foot to the sole plate 1 is attached to the front part of the front sole plate 1a.
a, and a heel fastening member 1 for fastening the heel to the rear end of the rear sole plate 1b.
1b is installed respectively.

This roller skate for beginners can be used by tilting the bottom plate 1 forward, touching the stopper 6 to the floor, and lifting the rear roller 55.
Although it can stand still, if you raise the stopper 6 and place both the front roller 5a and the rear roller 6b on the floor, the bottom plate l
Depending on where you put your weight, it moves either forward or backward,
The problem is that it is unstable, and if you are not used to it, it will suddenly move forward or backward regardless of your will, causing you to fall over, giving you a sense of fear.

<Problem to be solved by the invention> As mentioned above, conventional roller skates for beginners are unstable, giving users a sense of fear until they get used to them, and as a result, it is difficult to improve their skills. Therefore, there is a demand for roller skates for beginners that can stand stably.

An object of the present invention is to provide roller skates for beginners that solve the above problems.

Means for Solving the Problems> This will be explained with reference to FIGS. 1 to 4. In order to achieve the above object, the roller skates for beginners according to the present invention include:
It is composed as follows. That is, a pair of front and rear bottom plates 1a, lb are connected via a slide rail 2 so that the overall length can be adjusted, and a pair of front and rear legs 3a, 3b extending downward on both left and right sides of the lower surface of the bottom plate and the U-slide rail 2 are connected. Intermediate leg pair 3c
is combined. Horizontal cylindrical bodies 9a, 9b, 9c are connected to the left and right levers of each pair of legs 3a, 3b, 3c, and the horizontal cylindrical bodies 9
Roller shafts 4 a + at the centers of a, 9b, and 9c, respectively.
4b + 4c through its roller shaft 4a.

A front roller 5a, a rear roller 5b, and an intermediate roller 50 are pivotally supported at both ends of 4b and 4c, respectively. The intermediate roller 50 projects slightly downward with respect to the front roller 5a and the rear roller 5b, and a brake member 7 is interposed between the rear roller 5b and the pair of legs 3b.

Function> The roller skates for beginners configured as above are
By leaning forward slightly, placing the front roller 5a and middle roller 5c on the floor and letting the rear roller 5b float, you can move forward or backward.If you want to stop while skating, you can put your weight on your heel. The front roller 5a floats and the rear roller 5
Since the rear roller 5b and the intermediate roller 5c touch the floor and the brake member 7 makes it difficult for the rear roller 5b to rotate, it can be easily stopped and can stand still with peace of mind.

<Example> Example will be explained with reference to FIGS. 1 to 4.
The sole plate 1 on which feet with shoes are placed has one pair of front and rear sole plates 1a and l.
It is divided into b. The bottom plate 1 is connected by a slide rail 2 provided on the back side thereof so that it can be adjusted to a desired length. 3a, 3b+30 are three pairs of legs, which are connected in parallel on both sides of the lower surface of the bottom plate 1 and the slide rail 2. *9a, 9b, 9c are each leg pair 3.
a, 3b.

It is a horizontal cylindrical body connected to the left and right levers of 3c, and roller shafts 4a, 4b, and 4c are passed through the center of the horizontal cylinder, and a front roller 5a and a rear roller are mounted at both ends of the a-roller shafts 4a, 4b, and 4c, respectively. The roller 5b and intermediate roller 5c are supported by shafts.

The rollers are all made of a polymer material, and the intermediate roller 50 projects slightly downward relative to the other front roller 5a and rear roller 5b, and there is a brake between the rear roller 5b and the pair of legs 3b. The member 7 is interposed therebetween.

Next, the effect will be explained. Lean slightly forward, place the front roller 5a and intermediate roller 5c on the floor, and then press the rear roller 5.
When b is lifted, the front roller 5a and intermediate roller 5c
Both can move forward or backward. If you want to stop while skating, at any time, if you put your weight on your heel, the front roller 5a will float, the rear roller 5b and the intermediate roller 5c will touch the floor, and the brake member 7 will stop the rear roller 5b.
The brakes work against the vehicle, making it easy to stop and stand still with peace of mind. Therefore, in the initial stage of unfamiliarity, if you put your weight on your heel whenever necessary, the front roller 5a will float, the rear roller 5b and the intermediate roller 60 will touch the floor, and you can stop easily. You can practice roller skating with peace of mind, and as you improve, the need to use the rear roller 5b decreases, and you can use it in the same way as conventional roller skates.

<Effects of the Invention> Since the present invention is configured as described above, in the initial stage of inexperience, it is possible to stop easily by just lowering the heel, and the user can slide and stand still as desired without anxiety, and can enjoy practicing. It is easy to perform and improve quickly, and once you have mastered it, you will be able to skate with your heels raised just like the conventional method, and it is convenient for both beginners and experts.
