Description

BRAKING DEVICE FOR SKIROLLER, ROLLSKI OR SKIER

The invention relates to an operable with the leg, the calf or the lower leg brake device for roller skis or skis, which is pivotally mounted or mounted on the shoe (17) about a transverse or approximately transverse to the direction of rotation axis and mounted upon actuation by pushing back of the lower leg initiates a braking operation.

Roller skis, roller skis or skis are always used for both legs, so as a pair. The braking device according to the invention can be provided either only for one leg or also for both legs as needed. However, this application always describes only one braking device and can be used both for cross-country training scooter, touring-training scooter or other locomotion equipment on wheels or skis (in short, called "Rollski").

From DE 20201 1 109438 U1 a braking device with a specially rebuilt shoe is known which is already rotatably fixed or fixable on the user's shoe on a joint axis running transversely to the running direction. The disadvantage of this solution is that this brake device requires a shoe attachment or attachable to the user's shoe for articulation of the brake device and thus does not have the opportunity to grow this braking device on existing or standard ski boots without special conversion or attachment of their own shoe connection device can. In addition, this braking device is permanently moved over the lower leg cuff over the entire lower leg movement path, but because of the deviating Bremsvorrichtungsanlenkachse to the ankle movement axis, the lower leg up and down and thus permanently scrubbing on the lower leg. Due to the permanent full movement of the braking device and the joint is subjected to the Bremsvorrichtungsanlenkachse more intense.

From DE 20200901 1587 U1 a retrofit calf braking device is known, which, however, can only be mounted on the sports device and not on the ski boot of the user. DE 20201 1050177 U1 discloses a leg-actuated roller skid brake which is articulated on the roller skate frame. The disadvantage of this system is that the weight of the brake is on the roller skis and thus the weight distribution on the roller skis is unfavorable, since even with roller skates balancing between front and rear frame, similar to cross-country skis, is advantageous.

Roller skis are also known to have mudguards that are always fixed directly to the skis. Especially the mudguards on the rear wheel also causes an unfavorable weight ratio on the roller skis.

Various cross skates also have calf braking devices, which are articulated either on the shoe or frame, on a Glenksachse running transversely to the direction of travel. Rollers, unlike skis, are difficult or not at all to be braked transversely to the direction of travel for braking. Even in cross-country skis, it is often difficult in the deep snow, these can put across to decelerate, so it is conceivable to bring this braking device in conjunction with skis used.

There are roller skis with binding systems on which the user's shoe is either detachable or fixated on the roll ski only in the toe or foot ball area and the fixed variant in which the shoe is additionally fixed in the heel area. As a third variant, there is still the variable solution in which the heel is fixable or detachable. For a better understanding I name the binding variant with free heel "heel-free binding", the completely fixed variant "heel-fix binding" and the switchable variant "heel-variable binding". With the heel-free binding is always equal to the unblocked setting of heel-variable binding meant.

Fersenfixe bindings are mostly used in roller skates in the cross skate sector, as the user has more stability against uncontrolled tilting forwards available.

However, classic cross-country skiing or touring can not be satisfactorily imitated with heel-to-toe bindings on roller skis. Although skating is almost possible with heel-fixed bindings, it can only be imitated with heel-free bindings on roller skis as a round and dynamic cross-country skating movement.

Especially with roller skis with heel-free bindings braking devices that are articulated on the roller skis are perceived as more disturbing than roller skis with heel-fixed bindings. This is the reason why the braking devices in connection with heel-free bindings are primarily hinged to the shoe. It is ideal if the articulation of the braking device takes place on a joint axis extending transversely or approximately transversely to the running direction, which is as close as possible to the direction of rotation

Joint axis of the user's ankle is located. In this case, a calf cuff around the lower leg is appropriate for operating the brake, since during movements in the ankle, the calf cuff always moves to the lower leg in approximately the same height and thus does not rub on the lower leg. In this embodiment, the calf cuff can also support the lateral support of the user in the shoe at the same time.

Commercially available cross-country, touring, sport, leisure or ski boots (hereinafter referred to as "shoes") do not have sufficient stability in the ankle area in order to be able to articulate a retrofittable braking system on a joint axis extending transversely to the running direction in the vicinity of the ankle joint axis , The articulation of a braking device can therefore be carried out in commercial shoes only in the sole region and from the previously known prior art, even after special conversion of such a shoe. In addition, it is problematic in this Anlenk-joint axis deviation to the ankle joint axis when the braking device is moved with a calf cuff on the entire lower leg movement path, because in this joint axis deviation, the calf cuff significantly up to the lower leg and moves. In order for braking devices that can be retrofitted to shoes to be used successfully at all, it is necessary that a braking device can also be mounted on the shoe without prior modification. So that after a mounting the brake shoe then also cleanly engages the wheel to be braked, it is also helpful if the brake device, without pretreated shoe, at individually matching points, with strapped shoe in the binding of the skate is fixable.

The braking device according to the invention is therefore designed as a pincer-like strap, clasp, ferrule or other self-supporting frame (called "pincer-like strap") and equipped with at least 2 pointed teeth and / or other articulated on the shoe element, after the feasting of the pincer-like bracket on the shoe also in addition to the shoe with screws or other fixing elements are additionally fixable. Both brake shoe, brake device struts and lower leg contact part are fix or adjustable fixable attached to the pliers-like strap. Thus, the entire brake device is built on the forceps-like bracket and with the 2 pointed teeth, the entire braking device can be tweaked at any point to a shoe. So that the teeth find sufficient support on the shoe, the corresponding tooth application points on the shoe can be improved thermally, with a hole or a drill. With this construction, the brake device does not need a calf cuff on Lower leg to be attached. So then has the lower leg with the braking device no permanent contact. An elastic element pulls the brake device only so far to the shoe, that the brake shoe in the braked state, only to just above the wheel to be braked lifts. The pincer-like strap is either so tightly mounted on the shoe that this pincer-like strap can be pulled or held only limited to the shoe with an elastic element, or the braking device is equipped with a corresponding adjustable brake device stop which shortly after lifting the brake shoe from the rear wheel then comes to the shoe. The limited mobility of the braking device has the advantage that the braking device always has only briefly during braking or possibly when lifting the heel in contact with the lower leg and so a permanent chafing on the lower leg is impossible. The articulation points of the teeth on the shoe are thus exposed to less wear.

A minimal elasticity of the pliers-like bracket has the advantage that conical teeth adjust after any material wear to the shoe and thus the linkage remains permanently free of play over a long time.

To brake a roller ski, the brake shoe can also be designed as a brake pad that gets in contact with the ground during the braking process by pushing back the lower leg and thus slows down.

If the brake device is already mounted on the shoe, it is obvious that the mudguards are also mounted on the brake device or the brake shoe is designed as a mudguard or a mudguard which can be fixed to the brake shoe is provided. A fender on the rear wheel would be in any case in connection with a braking device in the way and the weight distribution on the roller skis is not advantageous with a roller ski mounted mudguard. A Kotschuetzermontage, however, on the shoe is advantageous because a weight on the shoe is not as disturbing as the weight on the rear frame of a roller ski, if this has a heel-free binding. Fig. 1 shows the braking device from slightly obliquely above.

Fig. 2 to 5 show the braking device in different operating situations.

As can be seen in Fig. 1, the pincer-like bracket (1) extends from the adjustable teeth (2a and 2b) to the rear over the brake shoe (5) to the rear strut fitting (9). The brake shoe (5) and the brake device stop (3) are held together with at least one brake device screw connection (6) or other fixing element. This construction allows the brake shoe (5) to be designed as a simple angle profile. The brake shoe (5) can also be designed as at least one brake pad, which decelerates during grounding during braking. Or the brake shoe (5) is designed for use on skis as a claw that brakes the ride safely during the braking process by scratching in the snow or on ice.

The brake device stop (3) is ideally provided with a slot, so that with this stop the movement path of the pliers-like bracket (1) on the user's shoe is definable, since it is sufficient if the brake shoe (5) in the unrestrained state only minimally from the rear wheel of the Rollski ^' s lifts off. Thus, the brake shoe (5) is lifted in the unbraked state of the rear wheel, the braking device with an elastic element (4) is held resiliently to the shoe of the user. The brake device stop (3) is not needed in very close to the shoe mounted brake device and therefore may possibly be omitted. The adjustability of the teeth (2 a and 2 b) does not necessarily have to be possible on both sides and can also be ensured by means of a quick-action clamping device or the pincer-like bracket (1) is designed as at least one quick-release clamp or ferrule. This would have the advantage that the braking device would quickly be fully on and off. The pliers-like bracket (1) can be designed to be minimally elastic, because in case of possible material wear between the conical teeth and the shoe, thereby the connection between the brake device and shoe independently and thus the articulated linkage of the brake device to the shoe (17) remains free of play longer , For adjustable fixation of the contact part (12) on the pliers-like bracket (1) is a 3-point construction with struts and slots or instead of the slots with several holes next to each other. The lateral struts (8a and 8b) are provided at the upper end with StellLanglöchern (1 1) and connected to the lower end with the pliers-like bracket (1). The main strut (7) is at the lower end via the rear strut fitting (9) or other connecting element with the pliers-like bracket (1) fixed or approximately fixed. At the upper end of the main strut (7) via the contact part connection (10) or other connecting element of the contact part (12) fixed or movable grown. Between the lower and upper end of the main strut (7) meet the lateral struts (8a and 8b) to the main strut (7) and are at this point with the main strut (7) via at least one screw, split pin or quick release (14) or other connecting element adjustable or fix connected. Additional adjustment holes (15) or slots allow a further adjustment in adjusting the contact part position to the lower leg of the user. Whether the lateral struts (8a and 8b) at the rear and the main strut (7) are mounted in front of the pliers-like bracket (1) or vice versa has no influence on the operation of the brake device. With this or similar 3-point construction of the contact part holder is not only the possibility to position the contact part to the lower leg of the user in the direction according to, but also transverse to the direction, so then always meets the lower leg on the contact part (12) during braking , Whether the adjustment slots are on the side struts (8a and 8b) at the top and / or bottom end and / or on the main strut is irrelevant to an effective adjustment function of the contact part position. The elastic element (4) can also be embodied as a rubber band, tension-compression or leaf spring under, above, in front of or behind the braking device to the shoe. The elastic element only needs to fulfill the purpose that the braking device is resiliently held to the shoe. If the elastic element (4a) is stretched over the shoe, it is important that it is releasably fixed to the brake device at least at one point or is detachably connected to one another at at least one point. Comfortable, however, is a pliers-like bracket (1) mounted leaf spring (4b), which extends next to the shoe sole (18) below the shot fs (17) approximately in the direction and with some bias on the shoe bottom and thereby the brake device resilient to the shoe (17) stops. This has the advantage that the entry and exit of the user in the shoe (17) is in no way impaired by the braking device. As shown in FIG. 2, the tong-like bracket (1) with the teeth (2) on the shoe sole (18) of the shoe (17) articulated hinged limited to a transverse or approximately transverse to the direction of the joint axis and is connected to the elastic Element (4), in this example with the leaf spring (4b), resiliently held to the shoe (17). The shoe (17) is articulated on the roller skate frame (19) with a heel-free binding on the toe joint (24) articulated on a pivot axis extending transversely to the running direction or hinged in an articulated manner. The contact part (12) touches, with the lower leg (23) and contact of the shoe sole (18) with the Rollskirahmen (19), neither the lower leg (23) nor the shoe (17). The brake shoe (5) is only slightly lifted from the rear wheel (20) of the Rollskirahmens (19), since the pliers-like bracket (1) or the brake device stopper (3) abuts the shoe (17).

In order to prevent dirt from being splashed on any dirty surfaces of the user, mudguards can also be mounted. The Kotschützer (22) keeps the dirt and water from the front wheel (21) and is mounted on the Rollskirahmen (19). The Kotschützer (16) for the rear wheel (20) is mounted on the brake shoe, the Kotschützer can also be the brake shoe at the same time. The mudguard for the rear wheel (20) may also be mounted or mountable directly on the user's shoe (17) or on the braking device.

Fig. 3 shows Fig. 2 with reclined lower leg (23) and with elastic element (4a). In this case, over the contact part (12) with the lower leg (23) overcomes the spring force of the elastic element (4a) and so pressed the brake shoe (5) on the rear wheel (20) and braked. So that excellent braking effects can generally be achieved with calf brakes, it is in any case necessary for the user's body weight to be shifted to the heel during a braking operation. Therefore, in heel-free bindings, even when braking the heel of the shoe (17) need not be fixed to the Rollskirahmen (19).

Fig. 4 shows Fig. 3 with lifted shoe sole (18) from the Rollskirahmen (19). Especially during the skating step, it may happen that the lower leg (23) presses the brake device even further backwards via the contact part (12) than during normal braking - see FIG. 3. With ΉΓ, a point on the lower leg is defined, up to where in the In extreme cases, the contact part (12) moves on the lower leg so that the difference to Ή2 "in FIG. 5 can be recognized. Fig. 5 shows Fig. 2 with an additional, only indicated by dashed lines braking device with only suggestively fitting contact part (12) and with elastic element (4a). With this figure, the other extreme position of the lower leg (23) is shown to show how far Ή2 "would differ from ΉΓ (Figure 4), the articulation of the brake device on the shoe (17) would not be minimized According to experience, between ΉΓ and "H2" is on average 20 mm, which should make it clear that a permanent entrainment of the brake device via a

Calf cuff with the lower leg would actually be problematic. Therefore, the contact part (12) instead of a calf cuff, both in terms of ease of use when putting on the shoe (17) and because of the predominantly contactless movement possibility of the lower leg (23), advantageous.
