Definitions

• 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.
• 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.
• the present patent application aims to change this situation.
• a distinction can be made according to the criterion of where the braking effect is achieved and how the braking effect is triggered.
• 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.
• 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).
• 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.
• 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 Vorumblen 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.
• the system is, as is usual with other vehicles equipped with a brake light to make the braking process recognizable even at night.
• 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.
• 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
• a brake drum which is incorporated in the roller rim.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• the transmission element 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.
• 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.
• 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.
• a front and a rear second sliding part 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.
• the threaded rod may be connected to the formed as a band transmission member and actuated by the shaft rotatably supported on the roller.
• 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.
• 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.
• 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.
• 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.
• the contact pressure of the brake device depends 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.
• 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.
• the transmission member is designed as a lever, it requires a second return spring for the same reason.
• 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.
• 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.
