NL1017292C1 - Brake system for inline skates involves rotatable suspension of running wheels with position-alterable parallelogram frame - Google Patents

Abstract

The brake system for inline skates involves a rotatable suspension of the running wheels (A,B,C,D) with a position-alterable parallelogram frame. Through the rotation of the suspension of the running wheels in relation to the skate frame by one or more running wheels directly or by a sloping or lever effect a brake body (R) is pressed against a running wheel, so that a rotating running wheel is braked.

Description

Title: Inline skate brake system

The invention relates to a system with which inline skates can be made brakable. Practically all used inline skates do not have a 5-brake system.

The skater must, when using non-braked skates, in the event of a braking emergency by using. a special technique, e.g. by making frequent short turns or by dragging one inline skate along the surface, try to limit his speed.

10 In the event of an emergency stop, the skater often runs into major problems. Stopping often does not succeed in time and falls and accidents are numerous.

The invention has for its object to provide a system with which the inline skater can brake by moving one or both skates out of the skating direction, i.e. obliquely to the skating direction. As a result of this movement a braking action 15 is activated, as a result of which one or more running wheels are braked.

Braking is the same in normal ice skating and skiing. Resistance is also generated here by tilting one or both skates or skis. This braking operation is known to skaters and skiers and this gives those persons who also want to inline skate a familiar feeling and no need to switch to a different braking method.

The braking effect according to the invention is obtained in that the suspension of the wheels of the in-line skates is rotatable, so that in the event of a deviation from the straight-skating direction at least one wheel runs against and along a brake body.

One possible version is described here: A pair of inline skates executed with swivel-mounted wheels by means of a so-called parallelogram frame.

At least one flexible stretchable rubber strip or spring (v) always keeps the wheels in the unloaded position in the longitudinal direction = straight line of the inline skate.

The invention will be further elucidated with reference to the drawings which provide an image of the braking system.

Drawing (1) shows the placement of four rotatably suspended wheels A, B, C and D in a straight-ahead position under the frame, consisting of three parallelograms. The long sides are formed by the wheel carriers E and F, which relative to each other by means of hinges can shift according to the arrow directions. The wheels are mounted on the short sides of the 35 parallelograms.

The wheel carriers E and F can be obtained by means of displacement of the feet relative to each other, so that the wheels are brought out of the straight-through position and a braking effect occurs as soon as the running wheels run along and against the brake bodies R.

The foot rotation mechanism is designed such that when a foot is turned inwards (toes inwards) the wheels turn outwards and vice versa. If desired, a twist stop (S) can also be fitted, so that only foot rotation to one (= inner) side is possible. In this way a skate pair can be created in which the skater can only brake according to the "Schneefluch" method. This version offers advantages with stronger sales when skating, ie

1 o "slipping" when depositing is then impossible.

Drawing (2) shows the position of the wheels in non-straight position of the skate. The spring (V) is stretched in this position and ensures the return movement to straight through in the unloaded state.

The (slightly collapsible) brake bodies are arranged on the wheel carriers which touch the wheels and brake when not straight ahead.

Drawing (3) gives a schematic picture of the rotation of the feet relative to the parallelogram wheel carriers. The front and back of the shoe are rotatably attached to the skate parallelogram.

It will be clear: the front of the shoe moves to the left in the direction of the arrow, the wheels and thus the walking direction move to the right.

Drawing (4) shows a possibility of turning the wheel suspensions in the forced directional change system equipped with a parallelogram pivot wheel version, i.e. a suspension with the pivot point of a wheel lying in front of the axis of this wheel.

By uniformly reducing this distance (s) from the center of the skate to the ends, whereby the front wheels swivel forwards and the rear wheels to the rear or from the first to the last weed in the row as drawn, to reduce evenly to 0 ( distance from the pivot suspension to the axle of the wheel = 0), it is achieved that the wheels do not all swing to one side in an uncontrolled manner with a lateral load on the skate. This fact is obtained because in this way one fixed support point is created in the row of wheels, which gives the skate a more stable position.

In addition, with an inclined position (with respect to the vertical surface) of the skate, all wheels remain in contact with the ground.

Claims (4)

Braking system for inline skates, characterized in that the suspension of the running wheels of the skates is rotatable, by a position-adjustable parallelogram frame, wherein by rotating the suspension of the running wheels by means of. foot rotation relative to the skate frame on one or more running wheels, directly or via a ramp or lever action a brake body is pressed against or on the running wheel, thereby slowing a rotating running wheel. Braking system for inline skates according to claim 1, characterized in that the distance from the suspension pivot point to the axis of the running wheel from the center of the skate to the ends is reduced per wheel or reduced from the first to the last wheel in the row and with the front wheels swiveling forward and the rear wheels swiveling back. 15 Braking system for inline skates according to claims 1 and 2, characterized in that the pivoting movement of the running wheels is created via hinges mounted on the skate frame or by separate castors. 20 Braking system for inline skates according to claims 1, 2 and 3, characterized in that only the inclined position of the shoe relative to the inline skate brings about the braking effect. The suspension of the wheels of the inline skate does not twist, so the wheels remain inline.
