Sports equipment with wheels

The innovation concerns sports equipment with wheels e.g. Roller skates, in-line skates, skate boards and similar sports equipment.

Such sports articles are becoming increasingly popular and are available in a wide variety of designs.

So there is e.g. In-line skates and skate boards for game and Hobby area, and for the beginner and versions for the professional u. Sports area.

Due to the great topicality, sports equipment of this type is not only used today on designated places or tracks with smooth surfaces. But practically everywhere where the floor seems to offer suitable rolling options. In order to be able to carry out this activity at all, compromises are necessarily made here.

Among other things, this means that very often on relatively poor ground, e.g. On uneven sidewalks and cobbled streets with corresponding depressions, hollows and edges, the activity with these sports equipment such as running with inline skates, skate boards, roller skates and the like.

Particularly uncomfortable and for the joints of the

Sports equipment users are often very harmful

Shocks caused by the unevenness, the unsuitable tread and the joints of the

Users of these sports equipment can be transferred.

With e.g. the installation of soft roles in the rolling system of the previously known sports equipment is only insufficiently guaranteed a satisfactory running quality.

Especially in the case of soft rollers, the ease of running suffers greatly due to the greater adhesion of these soft rollers, and this

Rolls are also worn out quickly.

Due to the fact that on uneven floors often only two of the four to five castors e.g. of an in-line skate is in contact with the ground, which is the risk of slipping and thus

Accident risk quite large. In addition, the braking properties of many sports equipment due to their simple braking system

Particularly bad use on odd soils and mean an additional one for the user but also for others

Danger. In general, according to the state of the art, in the known sports equipment with rollers, such as in-line skates, roller skates, skate boards and the like, each of the baptismal rollers running one behind the other is individually fixed in a largely rigid rail or holder, so that when running, for example with an in-line skate is evenly distributed on all rollers on even, even surfaces.

In the case of uneven surfaces, elevations and depressions of the floor surface often have only two castors in contact with the floor and are therefore exposed to a corresponding additional load. This is particularly uncomfortable for the user if such a heavily loaded roller when running on an obstacle such as e.g. an edge hits the floor tread, and this impact is fully transmitted to the user's joints. In addition, uneven contact of the rollers with the tread of the floor when pushing off is often fatal to the user because of the risk of slipping when running. The accident risk is also e.g. for athletes e.g. Cornering on uneven surfaces is particularly large due to the often only slight contact with the ground.

Another danger for the user of sports equipment with wheels is that the braking systems known up to now are often inadequate and also not by the users; or are insufficiently mastered.

That this braking problem has been recognized is shown by the fact that e.g. new brake systems are developed in the production of in-line skates.

For example, Braking systems for in-line skates that press a floor stopper onto the floor surface by lifting the front foot, or have a rolling floor stopper. Another so-called A.B.T. System works with a floor stopper that presses the floor stopper onto the floor by moving the ankle joint. Another braking system is known as a dual system, in which the heel of the foot is pressed down for braking. This system works against the pressure of stronger springs, which have to be adjusted according to the user's body weight.

Another complex brake development is, however, only known to date according to the manufacturer's brochure, in which a floor stopper is operated hydraulically and, according to the manufacturer, has a better braking effect than other systems. In general, however, no simple and satisfactory solution has yet been found. The object of the innovation according to the invention is to significantly improve a sports equipment generation which is popular with children, adolescents and adults, such as, for example, in-line skates, roller skates, skate boards, with regard to the following points. a) Regarding the health of the joints. When using this sports equipment due to less vibrations. b) With regard to more safety through better brakes and better grip. c) With regard to a generally better driving u. Rolling behavior to increase the enjoyment when using this sports equipment. d) With regard to a wide range of possible uses, e.g. better running properties when used on flat and uneven treads with the same roller hardness. e) With regard to universal applications, for example in cross-country skiing. Acrobatic sports area, in the hobby u. Professional area.

The main improvements in this Nβu development are achieved by the fact that sports equipment with wheels such as In-line skates, roller skates, skate boards and the like are designed according to the invention with a swinging roller system for the alignment of the rollers on uneven ground, connected with an effective braking system, which makes it possible to directly on at least one of the rollers, but preferably on at least two of the rollers to act so that when used e.g. when running with in-line skates equipped with the roller system according to the invention, keep all the rollers in contact with the ground due to their oscillating movements and keep at least two of these rollers in contact with the ground when braking.

For the production e.g. Materials such as metal, plastics, fiberglass, carbon and. Carbon fiber provided.

In the following, one of the possible design types, e.g. in an in-line skate, as mentioned in the claims and shown in the drawings in a simplified version.

For example, one possible way of implementing an in-line skate (FIG. 1-4) is to be equipped with four rollers so that two of these rollers (5) are fastened one after the other in a rocker arm (4) by means of axes (6) and these two rockers ( 4) one after the other by means of an oscillating axis (7) in a rail (3), or directly attached to the shoe. The rear rocker (4) is preferably provided with a brake (8), which acts on at least one of the rollers (5), preferably by lever arm action (18). In the rail (3) and or on the outer areas of the rockers (4), guide elements (21), for example sliders, sliding surfaces, guide pins or corresponding elongated beads and elevations and the like, are provided, which allow a precisely fitting opening and closing. Guarantee movement of the rockers (4) in the rail (3). These guide elements can be adjusted to regulate the movement of the wings. It is provided that the rockers may have a fixed or adjustable rocker stop (14) which, for example, is made of an elastic material and is designed in such a way that the rocking movement of the rocker (4) is limited in any direction, or the respective rocker in the desired manner Position can be determined.

For example, possible to set the swingarms so that the first and last rollers protrude a little further from the rail than the middle rollers. For professionals, this certain advantages in so-called gliding. In addition, it is optionally provided to equip the in-line skate with a swing-back system and at the same time with a swing-stop damper (13). This is advantageous for particularly uneven treads. The reset element can be shown in Fig.9 in the rail (3); but also in the rocker (4) preferably on the swing axis (7).

The Anglelchung the rollers of the vibrating system to the unevenness of the floor is done in that there are at least two rollers in a rocker which are guided by a correspondingly strong axis, but preferably also in a rail, and are fastened in this rail.

The axle is preferably arranged in the middle of the rocker between the two rollers. Preferably two of these rockers are arranged one behind the other in e.g. an in-line skate.

When using appropriate materials and a correspondingly stable construction, it is conceivable that the rocker (4) is suspended on one side on a frame part (3) and the rollers are attached on one side, similar to the technique of suspension of the wheels on motorcycles. When driving with this sports equipment, it is thus guaranteed that up to a predetermined limit, despite the unevenness of the floor, all four castors remain in contact with the floor. In addition, with the roller system according to the invention for this in-line skate, the weight of the user is evenly distributed over all four rollers. This has the great advantage that, for example, when colliding with elevations and edges, the impact on the rollers is substantially less than that of in-line skates of the previously known type. The vibration system (now distributed on four castors) has the further advantage that the weight of the in-line skate user is increased in stages by lever force transmission. This results in a previously unknown soft running feeling despite hard, more abrasion-resistant rollers.

The vibrations that occur when walking over bumps, which are otherwise transmitted to the joints of the sports equipment user, are significantly reduced with the innovation according to the invention, so that the joints are protected even when the in-line skating activity is carried out for a long time, and because of this brand new one Driving feeling is even more fun to watch this sport.

Other advantages are e.g. that when starting and pushing off, all four rollers adapt to the inequalities of the ground. For fast and art skating e.g. halv-pipe running is particularly valuable due to the possibility of adaptation, the castors of the in-line skate located in the swingarm, the desired ergonomic posture of the ankles by adjusting the angle of the in-line skate to the ground.

It is intended to equip sports equipment with rollers such as in-line skates with one or more rockers as required and sports equipment with rollers such as roller skates, skate boards and the like with one or more pairs of rockers. For these sports devices, brakes are preferably provided which act directly on the rollers (5) in the rocker (4); or act directly on the rollers that are firmly mounted in the rail (3).

It is preferably provided according to the invention that the brake system in the rear, but it is also conceivable that the brake system in the front area of the sports equipment; or is present in the front and rear area of the sports equipment. It is also provided that the brake systems known to date from the prior art, e.g. Brake systems with floor stoppers can be used.

However, it is also envisaged to use disc brakes in certain cases. A simplified type of disc brake is mentioned in claim 11. In the brake systems mentioned in the claims, which act directly on the rollers, it is provided that the brake pads are designed such that they preferably do not act directly on the tread but on the upper side region of the rollers in order to reduce the tread of the roller by the at Do not stress the resulting friction on the brakes.

The brake systems shown in FIGS. 8a + 8b are described below as exemplary embodiments of the brake systems mentioned in the claims, for example for an in-line skater. 6

In Fig. 8, the in-line skater has a swing system with two wings. A brake system is installed in the rear swing arm that acts on two rollers at the same time when a lever is pressed. By lifting the forefoot, the sports equipment (Fig. 8) is raised at the front, so that the edges of the rail (3) press on the lever arm (18). This force is transmitted to the brake pads (23) via a lever element.

The distance between lever arm and rail can be adjusted using a spacer screw. When braking, both rollers remain on the ground until the swing arm stops on the rail. This ensures safe braking.

FIG. 8b shows an approximately the same system as in FIG. 8. However, the brake lever is actuated here by moving an ankle element (24) located on the shoe with a pivot point (25) by moving the ankle and pressing the lever of the brake system β .

The distance between the shoe lever element and the brake lever is also adjustable here.

The systems described have the advantage that e.g. in Fig. 8 at least two rollers remain on the ground when braking, and that in Fig. 8a + 8b all four rollers remain on the ground. This ensures a more secure braking than with the known systems.

A particularly noteworthy ABS-like effect results with the brake system 8 + βa, when used e.g. of the in-line skate on rough, uneven treads. This happens in that the swingarm is the bumps of the floor by appropriate Auf-u. Adjust movements.

At the contact point between the rail (3) and lever (18}, this stuttering movement is transmitted to the brake pads when the brakes are applied sensitively and causes an ABS-like, advantageous Bre β effect.

In Fig.8b, the lower brake lever is curved and presses a sliding u. Rolling element (32) and lever elements (33) on the brake pads (23) The curvature in the brake lever is adapted to the radius of the swinging movement of the rocker arm, so that the distance between the brake lever and the rolling element is also open and closed. Movement of the swing arm remains constant.

To return the rocker to the starting position, the most varied of options are mentioned in the claims. A simple and effective option is to attach two rockers, with the sides facing you, with a pre-tensioned tension spring, preferably at the level of the suspension of the axles (7). Figure description

Figure 8

shows an in-line skater with a swing system with a further design option of a braking system in the rear foot area. Here, by lifting the front in-line skate (1), the rail stop zone (35) presses on a lever arm (18) with a lever element (33), which spreads two brake pads (23) located on an axis (7) in the direction of the rollers (5 ). The lever arm (18) is in the middle guide (34). which is further developed in the lower area to compensate for any tolerances and to ensure an even pressure of the brake pads (23) on both rollers.

Figure 8a) shows an approximately the same braking system as in Figure 8, but here the lever arm is actuated by a shoe lever element (24), which has an adjusting device for determining the distance (26) between the lever arm (18) and the shoe lever element (24). It is actuated by tilting the ankle or by pivoting the shoe lever element (24) backwards, so that when braking, all four rollers remain on the ground and the two rear rollers are braked. Figure 8b

Figure 8d

shows a further possibility of the braking system which consists of a brake pad (23 + 30), preferably adapted to the radius of the wheel, of preferably elastic material. This brake pad is connected by lever force by moving the shoe lever element (24) via the adjusting device (26) provided with a brake pressure damper (17). If necessary, a hydraulic brake pressure booster (37) is interposed here. F i gu r 8e

shows an in-line skate with an exemplary embodiment of the vibration system in which there are two rockers (4) arranged one behind the other and the rear rocker (4) receives a brake pad (23) working against the force of the spring. The brake lever (18) fastened to a frame or to a rail presses the brake block (23) when the shoe lever element (24) is actuated and rubs on the preferably upper side surfaces of the two rollers (5). Sliding or rolling elements are indicated between the radiused upper part of the brake pad and the radius of the brake lever (18). These cause the swingarm in your up-u. Downward movement is not affected even when the brake lever is operated.
