Description

ROLLER SKATES

The technical field to which the invention relates.

The invention relates to sports equipment, and more particularly to roller skates, each of which includes a support for the user's foot and wheels, the axes of which are fixed on the side of the support corresponding to the outside of the user's foot. The level of technology.

There are many inline skates. As a rule, they are made as standard - this is special stiff shoes that are well fixed on the user's foot, preventing the user from moving the foot in such shoes, on the basis of which at least one row of wheels is fixed. The disadvantage of such roller skates is the inconvenience of their operation due to the large load on the ankle and the inability of the user to remain when using roller skates in their shoes. In order to put on roller skates of the usual type, each time the user has to change shoes.

Also, the standard design of roller skates makes it irrational to use large-diameter wheels to ensure a smooth ride. If you put wheels with a diameter of 20 centimeters under the rollers, it will be non-functional, the leg will be far from the ground, and an unstable structure will turn out.

But, when the wheels are located on the side of the base of the roller skates, it becomes possible to use wheels of a much larger diameter than is commonly used in conventional roller skates. And such solutions are known. Thus, roller skates are known from the prior art, each of which includes a support for the user's foot and wheels, the axes of which are fixed on the side of the support corresponding to the outer side of the user's foot, see CNN2101234247A, 2007, a description of Chinese patent.

This device is the closest in technical essence to the claimed invention and is taken as a prototype to the proposed invention. The disadvantage of this device is the lack of ease of use of roller skates due to the fact that this design creates a significant load on the ankle, and the user's leg tends to bend inward when riding, causing him pain in the ankle area. Another disadvantage is the inability of the user to remain when using roller skates in their shoes. Still have to change shoes.

Disclosure of the invention.

Based on this original observation, the present invention mainly aims to offer roller skates, each of which includes: a support for the user's foot and wheels, the axes of which are fixed on the side of the support corresponding to the outside of the user's foot, allowing at least , smooth at least one of the above disadvantages, namely, to provide increased ease of use of roller skates by reducing the load on the ankle and the ability of the user to remain with roller skating in his shoes.

To achieve this goal, each support is made in the form of a platform under the user's shoes, having means for attaching the support to the user's shoes, and each support has a rack connected to it, having means for attaching the rack to the user's foot.

Due to this advantageous characteristic, it becomes possible to place and fix the user's leg in his shoes on the roller skate support, and it is also possible to transfer the load from the ankle to the user's lower leg, which is much larger in size, stronger and can withstand significantly more significant loads. In addition, the anatomical structure of the human body is designed so that if pressure is applied to the ankle region, then it bends inward, because this joint bends in the sagittal and frontal planes. If the pressure from the side is on the shin, then it does not bend inward, because nature did not provide for such an opportunity. Both the knee and the hip joint are designed so that the leg bends in the sagittal plane and does not bend in the frontal. It is this anatomical property of the human structure that is used in the invention. And with the proposed configuration, it becomes possible to evenly distribute the load over the shin area.

There is an embodiment of the invention in which each platform for the user's shoes is connected to its rack rigidly, without the possibility of its movement relative to the platform for shoes. Thanks to this advantageous characteristic, it is possible to fix the legs while simplifying the manufacture of the roller skates themselves. Indeed, the platform for shoes can even be made in the form of one part with a rack.

There is an alternative embodiment of the invention in which each platform for the user's shoes is connected to its rack through a swivel with the possibility of movement of the rack in the sagittal plane and fixing it for movement in the frontal plane. Due to this advantageous characteristic, it becomes possible to further increase the usability of roller skates by providing the possibility of foot movement relative to the lower leg when riding on roller skates, but while ensuring that the foot is fixed in the frontal plane.

There is a variant of the invention in which each rack is located on the side of the platform under the user's shoes, which corresponds to the inner side of the lower leg of the user. Thanks to this advantageous characteristic, it becomes possible to position the racks on the inside of the legs of the user.

There is an alternative embodiment of the invention in which each rack is located on that side of the platform for the user's shoes, which corresponds to the outside of the shin of the user. Due to this advantageous characteristic, it becomes possible to position the racks on the outside of the legs of the user, which helps to reduce the likelihood of the racks catching each other when riding on roller skates.

There is an embodiment of the invention in which each rack has means for adjusting the size of the rack to fit the size of the user's leg. Thanks to this advantageous characteristic, it is possible to use the same roller skates for people of different height and age. Since everyone has different sizes of legs, namely shins, then the sizes of the racks should correspond to the sizes of the shins of the user. In children, or people of small stature, such shin sizes are smaller than in adults or tall people. Due to the availability of funds adjusting the rack size to the user's foot size can be used by people of different height and age with the same roller skates.

There is, in addition, an embodiment of the invention in which each means of securing the support is made in at least one of: a flexible belt with a fastener, a flexible belt having sections with a fleece-like Velcro joint, a rope joint, and a carbine-type joint ". Owing to such an advantageous characteristic, it becomes possible to carry out specific means of fastening the support, which does not limit the use of similar mounting options in the present invention.

Owing to such an advantageous characteristic, it becomes possible to implement the rack fastening means in a specific way, which also does not limit the use of similar fastening options in the present invention.

There is an advantageous embodiment of the invention in which each platform for the user's shoes has a front vertical section restricting the movement of the user's foot. Thanks to this advantageous characteristic, it is possible to better fix the user's foot due to the fact that the foot is not only fixed by means of fixing the foot, for example, with straps, but also rests against a vertical section, which also fixes the foot, preventing forward movement. In addition, such a vertical section protects the user's foot from possible impacts.

Additionally, there is a variant of the invention in which each platform for the user's shoes has a side element rigidly connected to it, to which the axles of the wheels are attached. Due to this advantageous characteristic, it becomes possible to fasten the wheels not to the platform under the shoes, but to the side element connected to it, which simplifies the process of mounting, repairing the wheels, and also provides the possibility of installing additional components, for example, depreciation means.

There is such a variant of the invention in which the wheels have a means of depreciation of the wheels connected to the axles of the wheels and the side element.

6 - control panel, made in the form of a mobile phone type smartphone In figure 6 is indicated:

7 - individual elements of the site.

The pad is shown on the left in an even position, on the right in a curved position. It can be seen that this is the simplest production option for such a platform, which allows it to bend in one direction and not change shape in another. In general, there may be other implementations of such a solution.

In figure 7 is indicated:

8 - means of rotation of the axles of the wheels,

9 - means of rotation of the site,

91 - means of rotation of the elements of the rack

As already mentioned, in this new possible implementation of the invention, at least one of the wheels is made in the form of a motor wheel. In general, a motor-wheel is an assembly uniting a wheel and a traction motor, a power transmission and a brake system integrated into it (thus, each motor-wheel has an individual drive). The brake system may not enter the motor wheel.

In general, there may be an option when all the wheels are made in the form of motor wheels. The rotation of such wheels is ensured by supplying power from a rechargeable power source 4. This can be a battery that is located anywhere on the roller skates, on a platform, on a rack, and even in one of the wheels, which is not a motor wheel. Charging the battery itself can occur from an electrical outlet through an adapter, from another battery, from solar panels, and so on.

To control the rotation of the motor wheel in the present invention uses a control unit 5 mounted on roller skates. It sends electrical signals to the motor wheel, controlling its rotation speed. Since there are two roller skates, there may be an option when there is one common control unit 5 that transmits control signals wirelessly, or each of the roller skates has its own separate control unit 5. In this embodiment, each of the control units can independently receive commands from the control panel 6. And then the signals from the control panel can be transmitted to the control unit (or control units) both via wired and wireless communication. As an example, options such as WIFI, Bluetooth, GPRS, network on the radio modem; network on a cellular modem; infrared systems; VSAT system; system with SST technology; radio relay systems; laser communication systems and others.

In the embodiment, when the platform is made up of separate elements connected to each other in such a way as to allow the platform to bend away from the location of the wheels and to fix in a flat state towards the location of the wheels, it is understood that the individual elements of the platform 7 are made movable relative to each other, but mobility is only meant to be away from the location of the wheels. This can be achieved by performing individual elements of the platform 7 in the form of interconnected links, as is done, for example, in the tank track, in the watch strap. In this case, the mobility of the individual elements of the platform 7 in one direction is ensured by the presence of a hinge between them, and fixation in a flat state to the side to the location of the wheels is ensured by the abutment of the faces of different elements against each other.

In some figures, the arrow and the letter g indicate the direction of gravity. It shows the working position of the tank, namely oriented parallel to gravity. It is in this provision that the description is given and the words “above” or “below” are used.

In the embodiment, when the wheels are connected to the means of turning the axles of the wheels 8, which makes it possible to move the wheels of the roller skates to a position in which the user can walk in roller skates without the wheels touching the walking surface, the platform has means 9 for turning the platform, the following is implied.

Means 8 of rotation of the axles of the wheels can be a swivel mechanism that is rigidly attached to the site and to the axles of the wheels. Using the indicated swivel, the position of the axles of the wheels can be changed. At the same time, the wheels of the roller skates can occupy at least two possible positions: working (the wheels touch the surface for riding, you can use roller skates for riding) and non-working (the wheels are pressed to the user's foot, roller skates can only be used for walking).

At the same time, the platform is also rotated relative to the rack using the means of rotation of the platform 9. An example of the use of roller skates with the participation of funds 8 and 9 may be the following.

Figure 7A shows an embodiment in which the roller skates are in the working position, with the wheels being on the side of the platform for the user's shoes. If it is necessary to fold the wheels and bring the roller skates to the walking position:

1. rotate the platform 1 with wheels in the direction of the arrow in figure 7A;

2. under the weight of the wheels, they are rotated by means of the articulated means 8 under the action of gravity;

3. the platform by means of 9 is rotated around another direction shown in figure 7B, so that it can occupy a vertical position parallel to gravity; (Figure 7B just shows a variant in which the roller skates are in an intermediate position when the wheels rotate with respect to platform 1).

4. optionally fold the rack so that it does not interfere with walking, while the third means of folding the rack can be used, indicated in figures 7 A, B and C as 91, (in this case, rack elements 34 and 35, which are used for adjusting the rack to fit the size of the user's feet, but may not be them in the general case)

5. bring the lower part of the rack to the folded position, press against it a vertically located platform 1, to which, in turn, vertically arranged wheels are pressed, which is shown in figure 7C (figure 7 C shows the option in which the roller skates are located out of service;

6. if necessary, fix in any known manner all movable elements in the folded state so that they do not change their position when walking.

In General, the above options for the implementation of funds 8, 9 and 91 do not limit the implementation of these funds. Of course, each of them can have an additional means of fixation in extreme positions, which can be performed in different ways and is not shown in the figures.
