Roller skate

Description

The invention relates to a roller skate, in particular a roller skate with a wheel base, a shoe base, a shoe front, a shoe rear, a stop bar on the shoe front and a stop bar on the shoe rear, with fine adjustment options on the shoe front and shoe rear for dividing the different shoe sizes of adults and young people and after inserting your sports shoe directly into the cover of the wheel base and attaching a fabric band, the roller skate can be used. It saves the manufacturing costs for the shoe clothing and can significantly increase the effect of a roller skate and therefore the roller skate according to the invention will be profitable.

As is known, skiing is a good outdoor recreational activity for young people. Roller skates are an essential tool for skiing. Only with a comfortable roller skate of the right size can you enjoy skiing. If the size of a roller skate is too big or too small, you will definitely feel very uncomfortable. If a roller skate is too small, there is a risk of damaging a skier's foot. If a roller skate is too big, it will be loose after putting it on, so that a skier cannot skate well. On this ground, only with a suitable roller skate can you enjoy skiing.

Since all roller skates on the market are only available in standard sizes, consumers must choose the right shoe size carefully, otherwise the above-mentioned disadvantages will arise. Some conventional roller skates have no way of adjusting their sizes as desired, since all such roller skates have a cover of the same size. For this reason, the following disadvantages exist for both consumers and shoe manufacturers.

A consumer must first take off his sports shoe, put on a sock, and insert his foot into the cover of the roller skate. The cover and the casing of a roller skate are an inseparable part that must be purchased and used together.

In addition, there are a wide range of sizes of roller skates and there are still many different sizes for adults and children. Each size requires a suitable cover, so the shoe manufacturers have to make extensive covers.

Furthermore, young people grow up quickly and their feet grow larger and larger, so that after a certain period of time they will no longer be able to wear an old roller skate in a standard size and will have to buy a new roller skate. And after a certain period of time they will probably no longer be able to wear this new roller skate because of an enlarged foot! Some young people will even give up the sport because of this. The roller skates that can be purchased in shops have certain standard sizes and would therefore not be suitable for grown-up young people to use for a long period of time.

In a commercially available linear roller skate, the size of the roller base can be increased by adjusting the center of the roller base. But in a linear roller skate, all the rollers must be arranged in a line, otherwise it cannot be used. After adjusting the roller base, the distance between the front and rear rollers will be extended. Such adjustment will reduce the bearing capacity of the roller base, as well as cause the front and rear four-wheelers to bend in a curve due to a larger rotation due to an extended distance between the front and rear rollers, so that the roller skate cannot be skated well. A roller skate must be able to bear the weight of a wearer well, and adjustment of the roller skate affects the safety of the wearer. Inappropriate adjustment of a roller skate will reduce its bearing capacity and cannot bear its user well.

l· ¹ X

The invention is based on the task of constructing a new roller skate in such a way that the roller base and the shoe base are manufactured in one design using an injection molding process and can achieve a fine adjustment option on the front and rear parts of the shoe base. In a first purchase, the inventor attempts to make a shoe size adjustment using two dovetails arranged on the shoe base (see Fig. 1), namely a dovetail (B) is arranged on the front part of the shoe base to engage with another dovetail (D) present on the lower part of the shoe front part (C), so that the shoe front part (C) can slide on the shoe base (A). But after practical training, it was found that such a design would not work, since the dovetails cannot engage at an angle, but must engage vertically, and there would be a large fluctuation between the shoe base and the shoe front. For this reason, such a design is not at all suitable for use on roller skates.

It is therefore an important object of the present invention to provide a roller skate such that the roller base and the shoe base of the roller skate are manufactured in one design by injection molding and the shoe front and shoe rear are movably connected in order to be able to achieve a fine adjustment option on the shoe front and shoe rear for possible enlargement of the shoe base without damaging the roller base or reducing the load-bearing capacity of the roller base or shoe base, so that the roller skate is suitable for wearing by rapidly growing young people with enlarged feet.

Another object of the present invention is to provide a roller skate without a cover, so that when using the roller skate according to the invention, one can insert one's sports shoe directly into the housing of the roller skate, adjust the front part and rear part of the shoe accordingly, and then wind up the band, so that the inconvenience of using a conventional roller skate, that one has to take off one's sports shoe, can be avoided.

Another object of the present invention is to provide a roller skate without a fairing, so that such fairings no longer have to be manufactured in order to be able to reduce the manufacturing costs and the carrying weight, i.e. easy to manufacture and use.

Another object of the present invention is to provide a roller skate so that its size can be adjusted at any time to suit the foot enlargement of the young person.
