Description

Inline and roller skates with rocker brake

1. Technical area:

The present invention relates to inline and roller skates, characterized in that the boot is mounted on a rail connected to the rollers via an axle stabilized by a spring so that it can tilt forwards and backwards and can brake the front or rear pair of rollers depending on the tilting direction with the help of brake blocks attached under the sole of the boot.

2. State of the art:

There have been numerous attempts to create braking devices for inline skates. The simplest design is to attach a brake block to the rear part of the skates, which can drag on the ground by bending the skates, thereby exerting a braking effect. However, the braking effect of this design is low, especially since the braking required by the dragging process is difficult and often fails or is dangerous at high speeds. Other designs provide for braking the wheels themselves. However, all of these solutions are characterized by extremely complex or complicated technology, which would ultimately lead to a significant increase in the cost of inline skates.

The same applies to roller skates, although the usual brake block is usually attached at the front.

3. Description of the invention:

The invention is based on the object of creating inline and roller skates in which it is possible to brake two of the usual four wheels of a skate in a simple manner. According to the invention, the object is achieved in that - as shown in Fig. 1 to 4 using the example of inline skates - the boot 1 is connected to a pair of rails 4 / 4' which is essentially triangular in side view, the lower end of which is in turn rotatably connected to the pair of rails 3 / 3 ¹ via an axle 6. On the rail-

The rollers 2a to 2d are attached to the pair of rollers 3/3'. The pair of rails 4/4' and the pair of rails 3/3' are connected at points 8 and 8' in the selected embodiment via a stabilizing spring, in the selected embodiment the spiral spring 7, in such a way that a stable horizontal position of the boot 1 is essentially maintained and only when a corresponding force is exerted by tipping forwards or backwards do the brake blocks 5/5' attached to the front and rear of the sole of the boot 1 hit the pair of rollers 2a/2b or 2c/2d and brake them. The stabilizing spring 7 is preferably designed as a spring with an adjustable strength in order to take account of the different weights and preferences of the drivers.

When using the present invention, the rider preferably spreads his legs in the direction of travel, i.e. he moves one leg forwards and the other backwards. At the same time, but also alternatively, he raises the toes of the front leg and lowers those of the rear leg. In this way, the rider overcomes the stabilizing spring 7 and presses the brake block 5 on the front skate onto or between the rollers 2a and 2b and the brake block 5' on the rear skate onto or between the rollers 2c and 2d. The resulting braking of one pair of rollers on each skate with the rider's legs in an optimal position is extremely efficient and safe.

The same applies to roller skates, but with the difference that the front and rear pairs of wheels affected by braking are not arranged behind each other, but next to each other.

Fig.1 is a side view of the inline skates with the boot 1 in a horizontal position, the rails 3 and 4 connected by the rotating axle 6, the stabilizing spring 7 with the attachment points 8 and 8', the brake blocks 5 and 5' and the rollers 2a to 2d attached to the rail 3.

Fig. 2 shows a side view of the inline skates with a boot 1 tilted backwards with the stabilizing spring 7 tensioned and the brake block 5' pressing on the pair of rollers 2c and 2d.

Fig. 3 shows a side view of the inline skates with a boot 1 tilted forward with the stabilizing spring 7 tensioned and the brake block 5 pressing on the pair of wheels 2a and 2b.

Fig. 4 shows a cross-sectional view of the inline skates with the sole of the boot 1, the pair of rails 4 / 4\, the pair of rails 3 / 3', the connecting axle 6 and the stabilizing spring 7, which is connected to the rail 3 at point 8 and to the rail 4' at point 8'.

Claims (5)

1. Inline and roller skates, consisting of a boot 1 with a pair of rails attached underneath, which is connected at its lower end via a rotatable axle to a further pair of rails and the rollers attached to them, characterized in that the boot tends to be held in a horizontal position by at least one stabilizing spring connecting both pairs of rails, but can still be tilted forwards as well as backwards with the application of force, with brake blocks attached at the front and rear under the sole of the boot resting on the front or rear pair of rollers and braking each one. 2. Inline and roller skates according to claim 1, characterized in that the brake blocks are replaceable. 3. Inline and roller skates according to claim 1 or 2, characterized in that the pair of rails attached to the boot is essentially triangular in shape or semicircular in shape. 4. Inline and roller skates according to claims 1 to 3, characterized in that the stabilizing spring is strong enough to ensure a substantially horizontal position of the boot in the resting state, i.e. without the application of force, but sufficiently flexible to allow a sufficient tilting movement when force is applied, which can bring about the braking process. 5. Inline and roller skates according to claims 1 to 3, characterized in that the stabilizing spring is adjustable in its spring force.
