Fig. 2 shows a schematic view of the hard shell 105 with a rail 200 in a separate state. The hard shell 105 can be removed after loosening the screws in the direction of arrow. The hard shell 105 as part of the shoe 100 has a three-point fastening system with only three fastening devices 101 - 1, 101 - 2, 101 - 3 for fastening the shoe 100 to the rail 200. The three

Fastening devices 101-1, 101-2, 101-3 of the shoe 100 and the three corresponding fastening devices 201-1, 201-2 and 201-3 of the rail allow a

Triangular connection between shoe 100 and rail 200.

The fastening devices 101-1, 101-2, 101-3, 201-1, 201-2 and 201-3 are formed by openings into which

Fixing screws can be used. In general, the fastening devices 101 - 1, 101 - 2, 101 - 3 may also be formed in other ways, such as by a tendon from inside or outside or in

Binding system. The first fastening device 101 - 1 is arranged in a middle in the heel region III of the shoe 100. The second

Fastening device 101-2 is laterally offset from the first fastening device 101-1 on a foot outside in

Fastening device 101-2 is particularly in

Longitudinal direction of the shoe 100 offset to the first

Fastening device 101-1 towards the third

Fastening device 101-3 arranged.

The third fastening device 101-3 is laterally offset from the first fastening device 101-1 at one

Foot inside the bale area 113 of the shoe 100 is arranged. This triangle connection between shoe 100 and rail 200 provides due to the additional third mounting point, by the geometric arrangement and by the enlarged

Total contact surface a strong and stable connection

between shoe 100 and rail 200 for better power transmission.

The two front fastening devices 101-2 and 101-3 are arranged asymmetrically offset from one another. In this case, the outer fastening device 101-2 is arranged offset in the longitudinal direction of the shoe 100 to the first fastening device 101-1 towards the rear. This improves the

Power transmission again, since the outer

Fastener 101-2 lies directly under the outer ball of the foot. In general, the

Fasteners 101-2 and 101-3, however, also be arranged parallel and symmetrical. The front

Fastening devices 101-2 and 101-3 protrude from the bottom of the hard shell 105, so that a roller 207 can be arranged in the space between the fastening devices 101-2 and 101-3. The hard shell 105 has in particular the locations of the fastening devices 101-1, 101-2, 101-3 corresponding bulges. In this opposite the other hard shell 105 protruding bulges in particular the fastening devices 101-1, 101-2, 101-3 are arranged.

The fastening devices 101-1, 101-2, 101-3, 201-1, 201-2 and 201-3 are formed by elongate openings, so that inserted fastening screws can be displaced within the openings. The openings of the shoe 100 are formed as transverse slots, whereas the openings in the rail 200 are formed as longitudinal slots. The elongated openings in the shoe 100 and the elongated openings in the rail 200 together form a cross so that the shoe 100 and the rail 200 are in two directions against each other

can be moved. This allows the skate system 300 to be customized to anatomy or driving preferences. In general, the openings in the shoe 100 or the openings in the rail 200 may be made either as a round hole or as a longitudinal or transverse bar. The lateral fastening devices 201-2 and 201-3 of the rail 200 are formed on trapezoidal wing portions 205. The rail 200 includes a channel 203 which serves to receive the rollers 207. In general, the wing portions 205 may also have other shapes, such as rectangular or half-round. 3 shows a schematic view of a lower side of the hard shell 105. The metal plates 107 with the openings as fastening device 101-1, 101-2 and 101-3 are embedded in the hard shell 105 and form a flat contact surface 109 around the openings. At the contact surface 109, the shoe 100 and the rail 200 touch,

Inner side of the ball portion 113 is further offset toward the shoe tip as the fastening device 101-2 on the outside of the ball portion 113. In the heel area III is the fastening device 101-1. In the bottom of the hard shell 105 may additionally not shown recesses for the rollers 207 may be formed to the center of gravity of the

To further lower the roller skate system 300. In addition, the sole of the shoe 100 may be provided with stiffening elements, not shown.

The shoe 100 with the three-point attachment system allows a user to mount a rail 200 with rollers 207 in the summer or an ice skid (not shown in the winter) under the shoe 100. For this purpose, it is not necessary to use a respective complete system.

Fig. 5 shows a schematic view of an inside of the hard shell 105. From above into the openings of the

Fasteners 101-1, 101-2 and 101-3

For example, screw sleeves with an internal thread

used so that the hard shell 105 of the shoe 100 can be connected via screws with an external thread, which are used from below in fastening devices 201-1, 201-2 and 201-3 of the rail 200. In general, it is also possible to connect the shoe 100 and the rail 200 from above, ie from one side of the shoe, for example during speed skating. Fig. 6 shows a view of the rail 200. The rail 200 also has three mounting points with the

Fastening devices 201-1, 201-2 and 201-3, which are arranged under the heel and in the forefoot or ball area of the shoe 100. The rail 200 provides through the three fasteners 201-1, 201-2 and 201-3 as

Mounting points and the corresponding contact surfaces 213 between the shoe 100 and the rail 200 an improved security in the connection compared to a two-point system. The fastening devices 201-1, 201-2 and 201-3 are not arranged in a line, but exposed laterally in front of a Y-shape. The fastening devices 201-2 and 201-3 are for this purpose on the side

outstanding trapezoidal wing sections 205 of the

Rail 200. The mounting device 201-1 is

in particular arranged elevated relative to the fastening devices 201-2 and 201-3.

The rail 200 has a channel 203 with a U-profile, in which the rollers 207 are arranged. The

Fastening device 201-1 is arranged in particular above the center of the channel 203. The shaft of the rollers 207 is inserted into the openings 211. In the middle of the channel 203 additional struts or bridges can be arranged between the individual rollers 207 and between the side walls 215, by means of which the rail 200 is reinforced.

The channel 203 in the rail 200 makes it possible to build the rail 200 low to lower the center of gravity. It can be developed by rails 200, with

larger roller diameters are equipped and yet have no higher center of gravity. A user can drive faster with larger rollers 207 without having to sacrifice stand height over smaller model comparison models. Due to the low center of gravity the user does less

Keep work and do not tire so fast. In addition, the

Skaters keep static and dynamic loads at a high level for a long time.

For example, in a Freeskate, as a skate system 300 equipped with an asymmetrical 3-point rail and an 80 mm diameter roller, the center of gravity can be lowered by up to 15 mm from a freeskate with a conventional two-point - Mounting system is equipped with a mounting distance of 165 mm with the same roll size. As a result, a driver is faster in its final speed.

Fig. 7 shows a side view of the rail 200. The rear fastening device 201-1 is higher than the two front fastening devices 201-2 and 201-3. The two fastening devices 201-2 and 201-3 are such

arranged to lie below the uppermost point of a roller 207. The upper point of the roller 207 in the region of the fastening devices 201-2 and 201-3 is thus higher than the contact surfaces 213. The roller 207 is thus at least partially insertable between the wing sections 205 in the channel 203. By lowering the two

Fasteners 201-2 and 201-3 in the

protruding wing sections 205, the center of gravity of the skate system 300 can be lowered.

The three-point fastening system with the triangularly arranged fastening devices 101 and 201 is

opposite a fastening system with three one behind the other attachment points technically advantageous because the front two fastening devices 101-2 and 101-3 are arranged laterally under the ball of the foot. A skater is safer in the skate system 300, so that reduces the risk of accidents.

Since a mounting of the rail 200 in the skate system 300 is carried out via three screw connections, different roller sets can be quickly tested or driven without having to get used to new shoes 100. In addition, the components of the skate system 300, such as the shoe 100 or the rail 200, in the event of a defect in a quick and easy way can be replaced by loosening only three screws fastening «

In the case of the design of the rail 200 as a 3-roller setup, the agility of the skater improves as the skate

is lighter and also serves as the center role as a fulcrum. The skate system 300 may be adapted for speed skating, inline hockey, freeskating or fitness skating.
