Description

BRAKING DEVICE FOR ROLLING SHOES

The invention relates to a braking device for roller skates. It sets out a group of three inventions that are directly related to each other and together realize a single unified inventive idea.

The roller skates consist of a shell and a pivotable shaft and a mount which can be fastened to the shoe sole and rotatably supports a plurality of single or two-lane rollers arranged one behind the other. The braking device consists of at least one actuatable by the shoe upper, transfer member for deflecting the pivotal movement of the shoe upper in a substantially the longitudinal direction of the holder corresponding translational movement and at least one in the region of the holder or the shoe sole out first sliding part. Furthermore, the brake device has at least one brake shoe, which is brought to bear on a braking surface of a brake drum, which lies in the roller rim, upon actuation of the brake device.

As with all means of transport is also in single-track roller skates (in-line skates) and two-lane skates deceleration and braking a matter of great importance, since the health and well-being of the user, as well as the exploitation of the possibilities of the chassis, and ultimately the Driving pleasure is crucially determined by the reliable possibility of braking. Although inline skates or roller skates have long been known and have found widespread use in many countries, there is so far no common, marketable braking system that meets the requirements, as in all other chassis (cars, motorcycles, bicycles, scooters etc .) are self-evident. From this fact you can convince yourself at relevant fairs and in the catalogs of the brand manufacturers.

Standard brake fluid is still a brake stopper, mainly made of rubber or plastic, which is pressed by lifting a roller skate on the ground. Otherwise, for the most part, the possibility of deceleration and braking is left to the skills of the skater or in-line skater, which in extreme situations not only gives serious health hazards to users and other road users, but also many People are excluded from the positive sporting purposes and the possibilities of using roller skates and in-line skates, because they want to avoid the risk associated with the lack of braking opportunities.

It is therefore not surprising in this situation that for many years there are a large number of patent applications on the subject of braking devices for inline skates (roller skates). Despite this large number, however, at first glance, much to the astonishment of the observer of the development, there are still no marketable systems.

The inventors of the present patent application attributed this fact, after many years of experience with tests of various systems on three fundamental problem areas: First, as the most reasonable method is, even with the state of the art in other means of transport undoubtedly a braking effect on the roles dar. These are but with inline skates and roller skates relatively small and are therefore subject to braking extremely easy wear, which can lead to the destruction of the role after a short time. Finding a technically feasible solution is therefore much more difficult than it might seem at first glance.

Second, the possibilities of triggering a braking operation are limited. Among the issued patents, there are in the meantime quite a few, which ultimately do not meet the requirements in commercial application, but on the other hand block the application of new possibilities.

Third, although the in-principle feasibility of in-line skate brake systems, given the state of the art in related fields, is not a question, ultimately it is not just about technical feasibility, but above all about elegant, simple, visually not annoying, easy to handle installation and care solution that does not bother the user, which allows safe braking anytime, so it works very reliably without triggering by itself at the wrong time.

In short, the fact that there is a great need of the market for a solution, but a very large number of patent applications and patents have so far but led to no marketable solution, suggests that a satisfactory in every respect solution has not yet been found ,

The present patent application aims to change this situation. In the case of the braking devices for roller skates belonging to the prior art, a distinction can be made according to the criterion of where the braking effect is achieved and how the braking effect is triggered.

Methods of braking with a braking member on the ground, as shown for example in US 5197572, do not concern the present invention, since each method of braking on the ground is an anachronistic method and in any case involves at least one interfering part (eg the brake stub), and usually must be triggered in unstable posture. Not for nothing does this method not apply to other vehicles.

Methods of braking one's own brake rollers, as set forth, for example, in US Pat. No. 5,791,663, at least mean that there is an additional disturbing part on the shoe.

Disturbing parts are not just a matter of taste. It is also about the all-round sporty usability and safety of the user, because protruding parts can also cause accidents.

In the method of braking the rollers can be divided into three groups: brakes on the material of the roller surface itself, brakes on discs or brakes on drums, which still has to be distinguished whether only one or two or all front rollers can be braked. The braking on the roll material itself, as shown for example in DE 59609268, has the particular disadvantage that the braking operation must be performed on an elastic material, whereby on the one hand the roll material is abraded, but above all on the other hand, a blocking of the rollers can be brought about As a result, leads to plate-like abrasion of the roller on the ground and thus destroys the role. This occurs particularly easily with only one or two braked rollers (see, for example, US Pat. No. 6,749,203 or FR 2753106 or CA 2209344).

The braking of brake discs in turn requires relatively expensive lateral constructions to achieve a corresponding force deflection, as set forth, for example, in US 5657999 or CA 2318078. As a result, the systems are complex and disturbing - for example, the bracket is unnaturally wide due to the space required. Not least, an economic argument for marketability is of great importance here. Complicated constructions increase the cost Brake considerably and this then ultimately represents a crucial obstacle to the feasibility in the market.

In the case of brake drums, on the one hand, there is the possibility of forming them as brake cylinders projecting laterally from the roller (as shown, for example, in CA 2187679 or CA 2107312 or US Pat. No. 5997015), which again leads to the space problems and interference factors already mentioned and the rollers appear visually unfavorable leaves. On the other hand, it is possible to arrange the brake drum in the roller, as shown for example in DE 10159913 or in DE 19837364 and in US 5704617. Here, however, there is a crucial question regarding the simple and cost-effective implementation of the technical application: Can the role of such a system simply be taken out of the holder? This is a requirement that is indispensable because rollers of in-line skates need to be replaced after a certain period of time as they are then worn away by normal use. The solutions shown go, as it corresponds to the prior art in other types of vehicles, from drum brakes, in which the brake shoe is pivotally mounted and the actuation is carried out by a pivoting movement. This construction now requires that the pivot bearing of the brake shoe is supported on the support walls of the bracket. However, this fact makes an assembly of bracket, rollers, brake shoes and actuator extremely difficult and is a major obstacle to an interchangeability of roles, or there are additional costly design precautions to provide for the purpose of assembly.

In addition, it is also important in the articulation of brake shoes on a drum or a disc, as many roles can be braked at the same time. It is crucial that, in particular (in the event that there are four roles), the first three roles can be braked, because the last role should not be slowed down, otherwise there is a risk that the shoe is raised during braking , and thereby only the last role is braked, whereby only one role would be slowed down. But as many roles as possible should be braked at the same time, because the kinetic energy of the skater (skater) is then destroyed by the largest possible number of contact points between the roller and the ground (causing the user to decelerate or to a standstill) and because of the large number of Contact points the roll surface of each roll is spared! It may also be during braking once that a role has no contact with the ground, which then it is not braking effect and it is then of great importance that the other eligible roles to be braked. Systems that do not meet the requirement that the front wheels can be braked, so include a major disadvantage. With regard to the method of tripping, brake devices which are to be operated via a cable, as proposed for example in CA 2187679 or US 5791664, constitute an unpleasant disability for the user, as well as allowing braking in unstable posture, and thus themselves can become a danger to the user who may come through torques that come on the user's body during the braking process to action, to fall. Methods of toe braking such as shown in US 5758884 or in US 5657999, also allow for any time triggering (ie in non-secure posture) and the user an unpleasant and exhausting use of his toes.

In the triggering mechanisms, the best are those that occur via a shaft rotation. Such belong for a long time to the state of the art, as already shown in 1922 in US 1402010. What matters is how this triggering technique, as also shown in US Pat. No. 4,275,895, in EP0600274, in DE 59609268 or in EP 0964728, is connected. If, for example, a triggering mechanism originating from the shaft is transmitted by means of a transmission link, e.g. a lever, or a flexible band, as shown in DE 59609268 or EP 0964728, connected to a braking device which acts on the roller surface, the braking system is not the requirements for a braking operation, which prevents the blocking of the rollers as possible, and is ultimately useless. If such a braking device is not designed so that the rollers can be inserted into the holder in exchange with the corresponding parts of the brake system, this circumstance represents a crucial obstacle to a user-friendly solution, because the replacement of the rollers is then very complicated. Is an adjustment mechanism attached to optically unsuitable location on the transmission element, or parts of the brake device are arranged so that they protrude disturbing from the holder, creating a risk of accident is given, or it is not possible the wearer of the holder with visually enhancing openings (like today is usual), so this circumstance is again a not insignificant argument against a brake system that will often not visually appeal to the user. In the realities of the market, design issues are very often issues of critical importance.

According to the invention, therefore, it is a question of finding a uniform answer to all the problems addressed so far. The present invention, which is a group of three inventions, gives such an answer. It shows a particularly simple, easy to assemble, visually appealing, reliable and cost effective solution for a braking system that can not be triggered involuntarily, designed to minimize blockage of the rollers that works well on wet roads, only in stable posture - by Vorstrecken a leg, all rollers of the roller skates remain on the ground - can be triggered, the moment of the start of braking is individually adjustable, which can be used extremely space-saving in the holder, the braking device even with optically open holder is not disturbing visible. The system is designed so that ordinary soiling does not interfere with the function, it can be made with very low weight because of its simplicity, so that the total weight of the shoe is not appreciably affected. Ultimately, the system is, as is usual with other vehicles equipped with a brake light to make the braking process recognizable even at night.

All of these advantages and even more, not detailed here benefits are brought about by the interaction of three inventions, many of the advantages mentioned arise only by the interaction of the individual elements.

The first part of the invention group is characterized by the interaction of at least a first sliding part which is slidably held in the height of the roller axes within the carrier and to which the brake shoes are connected, and a brake drum which is incorporated in the roller rim. Upon actuation of the brake system, the brake shoe is brought to a brake surface of the brake drum by means of the first sliding part to the plant. The actuation is effected by a transmission member, which receives a shaft movement and forwards to the first sliding part.

The particular advantage of combining a first sliding part on which the brake shoes are located with a brake drum, which is incorporated in the rim, is firstly that the first sliding part and the rollers can be assembled before mounting the rollers and then together in the carrier can be inserted, whereby a very simple change of roles is possible.

Another advantage is that the first sliding part can easily reach all the front rollers, so that the brake system can thus act on all front rollers readily, such a construction allows an arrangement in which the brake mechanism is not externally visible, since the brake drum as part of the rim is not perceived as such. The first sliding parts can be used on both sides of the roller, whereby the braking force is distributed to the largest possible number of braking surfaces, which causes the most gentle but effective braking effect. Due to the exact guidance of the first sliding part, the brake shoe can be easily adjusted at the braking surface of the brake drum, which counteracts the blocking of the roller during the braking process.

In contrast to the articulation on the roll material is thus not slowed down to elastic material. For the brake shoes proven braking material can be used, which acts on the desired material of the brake drum, whereby the braking behavior can be influenced again. If the rim is e.g. is made of aluminum, so the brake drum can be made directly from the material of the rim, which is particularly high-quality brake systems, as they are already part of the state of the art in motorcycles and cars today. This system is particularly insensitive to rain and sand dust influences and remains fully functional. A fact that is not given when braking on the roll material itself! But it can also be used in the brake drum a separate cylindrical ring to make the braking characteristics of the braking surface on.

The value of this invention can be improved even if cylindrical sleeves (cylinders) are used as guide parts for the first sliding part, which have a guide groove for the first sliding part in concentric groove shape. In addition, these cylindrical sleeves, which have a central bore for the roller axis, still have a taper, which fits into the axial opening of the ball bearing, which rotatably supports the roller. The first sliding part has matching long slots, with a slightly larger hole next to it. Through the hole, the sleeves can be pushed into their guide grooves. In this way, the assembly is done so that the guide sleeves are inserted into the first sliding part, then the sleeves are pressed into the Rollenachsenöffhungen the ball bearings, then already now (possibly both sides) loosely connected to each other rollers, guide sleeves and first sliding parts in the holder inserted, and fixed by the roller axles. This particularly simple mounting option allows a particularly easy replacement of the rollers. It must therefore be provided in the holder no own guide and there is no separate guide member must be fixed in the attitude, since the roller axes, as soon as they are fixed automatically fix the guide sleeves. By this first invention, the brake system according to the invention is already well functioning, but until then the transmission member still relatively far below - about the height of the roller axes - on the (the) first sliding part (e) act and the first sliding parts receive an actuating direction from behind Forward. If the transmission link extends down to the height of the roller axes, this is visually unfavorable and the contact point between the transmission element and the first sliding part is possible damage due to carelessness (eg if the shoes fall to the ground, or the skater or roller skater approaches a curb) exposed, which increases the risk of accidents. Furthermore, the direction of actuation towards the front means that the first sliding part at the very front still has to carry a brake shoe which extends into the front of the brake drum, at least when expediently - to achieve a greater braking effect - the larger lateral surface of the brake drum is used as a braking surface. This has the consequence that the support of the holder must reach very far forward if they are to visually obscure the slide. This in turn results in an unfavorable influence on the optical design possibility of the holder. Finally, it is of great importance to be able to set the contact pressure of the brake mechanism on the production side, since too low a contact pressure can lead to an unsatisfactory brake result and an excessive contact pressure occasionally to an abrupt deceleration and damage to the rollers due to a blockage of the rollers.

To cope with these three problems mentioned above, a second invention is presented, which is directly related to the first invention and, together with the first invention, represents a group of inventions which realizes a single uniform inventive concept.

This second invention is characterized in that a second sliding part is provided and between the second and the first sliding part, a lever is installed. Now pushes the transmission member, the second sliding part and this in turn the lever, the first sliding part is actuated from front to back, whereby the above-mentioned optical problem with respect to the design of the holder is omitted, as a braking of the rearmost role for the reasons already stated not provided is. In addition, since the second sliding part can be kept as close as possible slidably below the heel, the transmission element only has to reach down to this height, whereby a risk of damage to the contact point between the transmission member and slide can be significantly reduced and a further optical "relief" of the braking device can be achieved the transmission member and the second sliding part also consist of two directly connected parts or even a single part.

For transmission links of the kind set out, adjustability for individual adjustment of the torque of the start of braking upon actuation of the brake device is generally provided. An adjustment mechanism is in principle of great importance, as each skater or roller skater e.g. has a different circumference of the lower leg. This means that in a backward movement of the shaft, the triggering is not done in the same position with each skater. An adjustability is therefore necessary to compensate for individual differences. It is highly desirable that the adjustment device protrude slightly from the shoe so that it does not interfere. This can be achieved either by the adjustment device is connected to the second sliding part, or by the adjusting device is provided by a simple rotating roller in the course of the transmission member according to the invention either. In the first case, the second sliding part itself must in turn consist of two sliding parts adjustable in their distance from each other (a front and a rear second sliding part), whereby the desired adjustability is then achieved. For example, then controls a threaded rod, the distance between the front and the rear second sliding part, which can be easily set the triggering time of the braking process. In the second case, for example, the threaded rod may be connected to the formed as a band transmission member and actuated by the shaft rotatably supported on the roller.

As a result of this arrangement of the adjustment device, only a small part of the adjusting mechanism is visible in the heel area in the first case, for example a rotary knob which actuates the threaded rod. Visually disappears the adjustment so that almost completely. Furthermore, it is in a position where it is well protected against accidental damage, because the shell is there wide and overhanging, and they can still be operated at this point well by the skater or skater. In the second case, the rotary roller is partially incorporated into the shaft, so that very little protrudes from it. Also at this point, the adjustment is very easy to operate.

If the transmission member is a flexible band, according to the invention, the guide rail is shaped so that it deflects the flexible band by about 90 °, so that it receives at the lower end of the guide rail a thrust direction which is more or less parallel to the sole. At the

9 SUPPLEMENTARY SHEET (RULE 2βy ~ The lower end of the flexible band then engages with the broad side in a transverse groove of the rear second sliding part, or is directly connected to the second sliding part or it is at its lower end directly the second sliding part. This is a particularly simple point of contact between the transmission member and second sliding part or the transmission member and the lever provided.

The lever is pivotally mounted via a pivot axis which is supported on the frame. At its upper end, it takes the impulse of the front second sliding part or the transmission member, which is formed in a band shape. At its lower end, it engages in the first sliding part and thereby actuates it. Depending on the height of the arrangement of the pivot axis can be controlled by the lever law, the contact pressure of the brake device. The deeper the pivot axis, the greater the contact pressure.

In all contact points, the parts that transmit the force effect of the shaft on the brake shoes, a simple contact surface that is able to pass an impulse is sufficient if provided as provided by a return spring on the first sliding part for a constant pressure against the direction of actuation. By simple impulse transmission via simple contact surfaces, the overall construction is again substantially simplified, which brings the advantages already mentioned with it.

Conveniently, there is for the second or the first sliding part a stop member which is fixed to the carrier or the shell, so that when the brake device is not operated, the return spring both the first sliding part, and the lever and the front and the rear second sliding part against this Stop part presses. This is of great importance, because in a simple way a very disturbing noise of the moving parts can be avoided. If the transmission member is designed as a lever, it requires a second return spring for the same reason. If the transmission member is designed as a flexible band, this second return spring is dispensed with, provided that this flexible band is fixedly connected to the shaft, since it then participates in each shaft movement. The stop member also prevents the brake shoe from being brought into abutment at an undesirable location of the brake drum, which is important to avoid accidental and undesirable braking.

Another problem area is that the braking process in the dark of incoming users of the roads is difficult or impossible to be detected. To this To overcome problems, a third invention is presented, which combines directly with the first two inventions and, together with the first two inventions represents a group of inventions, which realizes a single uniform inventive idea.

It should display a brake light braking. In order not to have to use a battery for this purpose, the following structure is provided according to the invention: In at least one of the rollers, a magnet is installed. Opposite him there is a micro-coil, so that is induced when passing the role of the coil in this current. The coil is now connected via lines with a switch and a brake light. The switch is arranged to make contact upon actuation of the brake system, thereby directing the induction current of the coil into the brake light, which thereby lights up.

In a more detailed description of the group of objects of the invention, first of all the wording "front", "behind", "above", "below""vertical" and "longitudinally stretched" is defined in more detail: It is always used by a roller skate or inline skate Shoe, the user has when driving forward in use. "Front" thus refers to the toe, "back" to the heel region, "top", "bottom", "vertical" results from the consideration of one on the Rolls upright roller skates and "elongated" means the longitudinal extent of the bracket.

A roller (4) of an in-line skate or roller skate has a rim (5) in the usual way two ball bearings (4.2) stuck, which in turn are pushed onto the roller axes (4.1). In the area of the rim (5) between the ball bearing (4.2) and the beginning of the actual roll material, for example polyurethane or rubber, there is enough space to exclude a brake drum (5). The brake drum has the shape of a cylindrical ring, which may protrude only so deep into the rim that enough material is left to ensure the ball bearing and the roll material sufficient support. In particular, inside the rim (5) a cylindrical core must remain, which connects the support of the ball bearings (4.2) with the support of the roll material. The brake drum (5) is therefore identical to the rim (5), since it only gives it a certain shape. In the so-called brake drum (5) resulting in two lateral surfaces, which serve as first and second braking surfaces (5.1 and 5.2). Depending on the contact pressure of the brake device, it will be cheaper to select the first (5.1) or the second (5.2) braking surface. The material of the rim (5) in the case described be suitable as a braking surface, which is the case for example with aluminum. However, it is also easily possible to mount a cylindrical ring (not shown) on one of the lateral surfaces, which makes it possible to use a material which is independent of the rim material (for example steel) as a braking surface. Also, this inserted ring itself may consist of brake material or have applied the brake material. It is particularly useful to provide the brake drum (5) on both sides of the rim (5). Also, rollers (4) that are not used for braking may have such brake drums (5), since they differ visually from conventional rims (5) only very slightly.

In order to achieve a braking effect, a brake shoe (6) extends into the brake drum (5) and can be brought into contact with one of the brake surfaces (5.1 or 5.2). The brake shoe (6) expediently has a shape that follows the shape of the braking surface (5.1 or 5.2), so it may be, for example, a sector cutout of a cylinder ring. It is attached laterally to a first sliding part (7). When the brake device is not actuated, the brake shoe (6) is in contact with the roller (4) in the recess of the brake drum (5) so that the roller can unroll freely. The first sliding part (7) must be in this case more or less in the height of the roller axes (4.1). It can also be just above the roller axes (4.1). His place is between the inside of a carrier (3.1) and a roll wall. So that the first sliding part (7) can be guided safely, there must be at least one guide groove (7.4) there. This guide groove (7.4) could also be a bore when the first sliding part (7) represents a round rod. The guide groove (7.4) can for example be incorporated directly into a carrier (3.1) of the holder (3). It can also be incorporated in the roller axes (4.1). It can also be in its own first guide part (8), which then has to be connectable to the carrier (3.1) or the roller axes (4.1). Conveniently, the first sliding part (7) is a rod with a rectangular cross section, said rod (plate) should have the smallest possible width.

A particularly simple and efficient solution for the first guide part (8) is to form it as a guide sleeve (8.1). This guide sleeve is a centrically bored cylinder (8.1), in which concentrically a guide groove, the guide groove (7.4), is incorporated. In addition, this guide sleeve (8.1) on one side a taper (8.1.2), which is dimensioned so that it fits exactly into the axle opening (4.3) of the ball bearing (4.2). As a result, they can already be pressed into the ball bearings (4.2) during assembly, which is a considerable advantage for the assembly process. In order that the guide sleeve (8.1) can give the desired guidance to the first sliding part (7), the first sliding part (7) must have a longitudinal slot (7.1), the edges of which are displaceable in the guide groove (7.4). So that the guide sleeve (8.1) can be inserted into the long slot (7.1), the first sliding part (7) next to the long slot (7.1) a correspondingly sized bore (7.2) through which the guide sleeve (8.1) in the long slot (7.1 ) can be used. If there are at least two of these guide sleeves (8.1), the first guide part (7) can thereby be guided unambiguously and safely when the roller shafts (4.1) are mounted. In order to achieve a particularly good braking result, both sides of the rollers such first sliding parts (7) can be provided. The assembly is then carried out so that first the guide sleeves (8.1) in the slots (7.1) of the first sliding parts (7) on which are already the brake shoes (6) are inserted. Then the guide sleeves (8.1) are pressed into the ball bearings (4.1) of the rollers (4). Then the "package" thus obtained is inserted into the carrier lane of the holder (3) and afterwards the rollers (4) are fixed to the roller axes (4.1), whereby then the guide sleeves (8.1) are fixed and the two first sliding parts (7 The support (3.1) of the holder (3) need not be taken apart during assembly, which is necessary for both the production technology as well as for the assembly process (which must be carried out with each roll change again) of considerable advantage. If such a combination of brake drum (5) and first sliding parts (7) by an example transmission element (13.1 or 13.2), which receives the shaft pivoting movement, the backward movement of a movable shaft which is pivotable, for example via a pivot bearing (2.1), and actuated to the one or the first (s) sliding part (s) (7), the brake shoe (s) (6) abuts on the braking surface (s) (5.1 or 5.2) and thereby acts as a brake , The transmission member (13.1 or 13.2) can be designed, for example, as a lever (13.1) or as a flexible band (13.2). A flexible band (13.2) is to be understood as meaning a flexible plate which is suitable for forwarding a force impulse. A flexible band (13.2) can also be understood to mean a flexible (round) rod. The transmission member (13.1 or 13.2) requires a support for its operation. This support is in a lever (13.1) a pivot bearing (13.1.1). This pivot bearing (13.1.1) can be secured by means of a support extension (10.1) on the shell (1) or the holder (3). In a flexible band, the support is formed by a guide rail (13.2.1), which in turn can be supported on the holder (3) or the shell (1). It is particularly advantageous if the guide rail (13.2.1) is incorporated directly into the shell (1) (without illustration). The flexible band (13.2) may also be formed as an extension of the lower edge of the shaft (1), as shown in Fig. 9. It is designed as an independent band (13.2.2) when the lower end of the flexible band (13.2.2) coincides with the second sliding part and at the upper end of the flexible band (13.2.2) is the adjusting device (1 1.3). The lower end of the transmission member (13.1 or 13.2) engages the rear end of the first sliding part (s) (7). If the first sliding parts (7) by a return spring (14), for example, a leg spring, which may be supported on the holder (3) or the sole (1.1) of the shell (1) are reset against the operating direction, so a simple enough Contact surface on which the transmission member (13.1 or 13> 2) can come into operative contact with the (the) first sliding parts (s) (7). In order to achieve an adjustability of the braking device, corresponding devices (in FIG. 7 without illustration) - as is known per se - are to be provided on the transmission element (13.1). If the adjusting device (11) is provided at the upper end of the flexible band (13.2.2), it may for example consist of a projection (2.2) of the shaft (2) which is connected or connectable to it, and of a rotary roller (2). 1 1.4), which has a threaded bore in the course of its axis of rotation, and of a threaded rod (1 1.5), which is actuated by the rotary roller (1 1.4). The threaded rod (11.5) is held in bores in the shaft extension (2.2) and the rotary roller (11.4) is located in a recess (2.2.1) of the shaft extension (2.2). The lower end of the threaded rod (1 1 .5) is connected to the flexible band (13.2.2). Upon actuation of the rotary roller (1 1.4), the threaded rod (11.5) as a result of - allowing a rotation - support in the recess (2.2.1) moves upwards or downwards in position, whereby the adjustment of the flexible band (13.2.2) he follows.

In order to achieve a further improvement of the present construction, according to the invention between the first sliding parts (7) and the operative contact surfaces of the transmission member (13.1 or 13.2) a reversing and optionally an adjusting device (11) attached.

It is one or more lever (12) which are pivotally supported on the holder (3), for example between the last and the penultimate roller (4) and at least a second sliding part (9), which also with the flexible band (13.2.2) can coincide. The pivotable support of the reversing lever (12), for example, by a pivot axis (12.1) take place, which can be continuous when using two reversing levers (12). The lower end of the reversing lever (12) now has an operative contact surface which acts on the first slide (7). For this purpose, a contact surface must be provided on the first slide (7). Such a shoulder surface may be, for example, a laterally projecting mandrel (not shown). Or it is in the first sliding part (7) at a suitable location a vertical slot (7.3) incorporated, at the edges of the lower end of the reversing lever (12) can engage. The reversing lever (12) can then have at its lower end in turn a spike-shaped projection, pin (12.2), which engages in the vertical slot (7.3).

In two-part design of the brake device, which means that in each roller side in the respective rim side a brake drum (5) and that there are at least two first sliding parts (7) with the corresponding brake shoes (6), it is expedient, even the lever (12) form at least two parts. The two upper ends of the lever (12) can then be additionally connected by a connecting part (15) to effect a better synchronicity of the Bewegunsablaufes the two lever (12). It is then also possible, for example, for the front second sliding part (9.2) or the lower end of the flexible band (13.2.2) to engage this connecting part (15).

The upper end of the reversing lever (12) has operative contact with a second sliding part (9) or the lower end of the flexible band (13.2.2). This second sliding part (9) or the lower end of the flexible band (13.2.2) is in the region below the heel part of the shell (1) within the holder (3) or the sole (1.1) or in a connectable to the sole Web plate (3.1.2) guided displaceable. In the simplest case, this sliding part is an elongated cuboid or a (round) rod, wherein the transmission member (13.1 or 13.2) then acts on the rear end of the second sliding part (9) and the reversing lever (12) at the front end. Or the second sliding part (9) is identical to the lower end of the flexible band (13.2.2). In these cases, the transmission element (13.1 or 13.2) itself has the adjusting device (11). The second sliding part (9) may then be in one piece. Its guidance takes place in guide grooves (9.3) which are located in the holder (3) or the sole (1.1) or a sole extension or in separate second guide parts (10). The use of own second guide parts (10) can be made for production reasons, also these second guide parts (10), especially if you use them in pairs, possibly also for having an approach (10.1 or 13.2.1), the as a holder for the pivot bearing (13.1.1) of the lever (13.1) or as a guide rail (13.2.1) of the flexible band (13.2) may be formed, as shown in Fig.10 and Fig.13. The second guide parts (10) must in turn then be connected to the holder (3) or the shell (1). If the transmission member (13.1 or 13.2) is a lever (13.1), then again a contact surface at the end of (the) second sliding parts (9) to ensure the actuation, but it can also at the rear (two-part) end of the second sliding part lateral lugs (9.1.2) be attached to which the lower ends of a two-part lever (13.1) can come into operative contact. If the transmission member (13.1 or 13.2) is a flexible band (13.2), then, for example, the connecting part (15) or the second sliding part (9) have a Quemut (9.1.1), in which the lower end of the flexible band (13.2 ) is able to intervene. However, it is also sufficient a simple contact surface.

The adjusting device (11) of the transmission member (13.1 or 13.2) can also be provided according to the invention such that the adjusting device (11) is connected to a second sliding part (9). This can be achieved by dividing the second sliding part (9) into a front (9.2) and a rear (9.1) second sliding part (9). Both parts are then held in operative connection by means of an adjustable spacer, for example a threaded rod (1.1.1). The threaded rod (11.1), is screwed through an elongated threaded hole (9.1.3) of the rear second sliding part (9.1), and is rotatably supported in a blind hole (9.2.1) in the front second sliding part (9.2). The threaded rod (11.1) has at its rear end a knob connected to it (11.2), by the operation of which they can vary by means of the threaded bore (9.1.3) in their effective length. Upon actuation of the brake device receives by means of the transmission member (13.1 or 13.2) of the rear second sliding part (9.1) an impulse, which is transmitted by means of the threaded rod (11.1), to the front second sliding part (9.2). The front end of the front second sliding part (9.2) transmits the impulse afterwards to the upper end of the reversing lever (12) or the connecting part (15) of two deflecting levers (12), which in turn the (the) first sliding part (s) (7 ) transmits the impulse (s), whereby the brake shoes (6) on the braking surfaces (5.1 or 5.2) are brought to bear. If the adjusting device (11) is connected to a flexible band (13.2.2), then the force impulse is transmitted directly to the connecting part (15) and afterwards to the reversing levers (12) and the first sliding parts (7).

The first or the second sliding part (7 or 9) is at rest by the return spring (14) against a stop member (not shown), on the holder (3) or the sole (1.1) or the second guide members (10) or the web plates (3.1.2) is pressed.

The support (3.1) of the holder (3) can today have standard openings (3.1.1), without the brake device is disturbing visible. The holder (3) may have various customary forms. In particular, the carrier (3.1) by web plates (3.1.2) can be connected to each other at parts of its upper edge. In this case, the web plates (3.1.2) are attached to the sole (1.1) of the shell (1).

On at least one of the rollers (4) or their rims (5) is laterally an opening for receiving a small magnet (16). In the region of the holder (3) or the sole (1.1) a small coil (17) is arranged gegengleich same, so that the magnet (16) with rotating rollers (4) on the coil (17) just pulls over and there a current induced. The ends of the winding wire of the coil (17) open into a circuit (18) which is interrupted by a small switch (19) and by a brake light (20) which at the rear end of the shell (1), of the shaft ( 2) or the holder (3) is fastened, wherein the switch (19) at any point of the movement chain of shaft (2), transmission member (13.1 or 13.2 or 13.2.2), second sliding part (9), lever (12 ) or first sliding part (7) is fixed so that it is actuated by a there fixed opposite approach as soon as the brake system is triggered by the driver. The approach on the shaft (2) or on the transmission member (13.1 or 13.2 or 13.2.2) or on the second sliding part (9) or on the reversing lever (12) or on the first sliding part (7) closes when actuated the contact of the switch (19) whereby the induction current from the coil (17) in the brake light (20) causes a lighting up.
