Abstract

The invention concerns an ice-skate boot or roller-skate boot, in particular for ice or roller hockey. The boot has a foot shell (1) and a backstay cuff (2) which is secured to the foot shell so as to pivot about a transverse pin (5), the foot shell (1) and cuff (2) being held together at their opening on the instep side via closure means. The invention is characterized in that the closure means for the foot shell (1) and cuff (2) are independent of one another, an open flexion region (17) being located between the upper edge (11) of the foot shell and the lower edge (9) of the cuff. The cuff (2) has two bending-resistant regions, a cuff rear part (3) articulated on the foot shell and a cuff front part (4) which can be secured relative to one another via closure means (15). The open flexion region (17) is covered by an impact-resistant, appropriately shaped guard (8) which is pivotably articulated. In a particularly advantageous manner, a shin guard (18) is detachably connected to the cuff front part (4) by means of securing components known per se, such that optimum protection and hold are ensured.

Description

Skate boots or roller skate boots for ice hockey or roller hockey

description

The invention relates to a skate boot or roller skate boot according to the preamble of claim 1, as used in particular for ice or roller hockey.

The nature of ice skates in general and of ice hockey skates in particular as they are manufactured and used today can be divided into two different construction methods.

The most common is the leather skate, at least partially covered with nylon. The boot part, which is firmly connected to the runners, is in principle constructed like a street boot. The boot shaft ends approx. 4 cm above the ankle. The lacing extends from the toe cap all the way to the upper end of the boot shaft. The tongue underneath protrudes about 5 to 15 cm beyond the lacing. The boot shaft is pulled up in the area of the Achilles tendon.

However, this leather ice skate boot has decisive disadvantages. First of all, it offers insufficient lateral stability for the ankle of the user, which, in contrast to natural locomotion, is exposed to a multiplied load due to a lever extended by means of the skid and the extremely narrow contact surface on the ice. Improved stability could be achieved through tighter lacing and / or an increased shaft. However, both measures would further restrict the required flexion and extension in the ankle.

The second main deficiency of the leather skate boot is precisely this mobility. The desired mobility with regard to the extension and bending of the foot from the ankle is first of all hampered by the continuous lacing with the tongue underneath. The necessary "deep" posture of the ice hockey key player and the necessary flexion in the ankle must be forced against the resistance described. Part of the shaft in the area of the eyelets must be bent and the tongue compressed. Both changes can be recognized permanently on used ice hockey boots. This disadvantage could only be alleviated if the user loosely adjusts the lacing, but this again is only possible at the expense of lateral stability. The extension of the foot, as is desirable as far as possible when pushing off the ice, is also restricted by the continuous tongue and the relatively stiff shaft extension in the area of the Achilles tendon.

In practice, the skate boot is deformed in the manner described above with each running step. This means the loss of part of the energy used. In addition, this construction, which is poorly adapted to the anatomical movement mechanism, prevents the best possible development of the physical possibilities in terms of skating.

Especially for the ice hockey player, this known skate boot is an at least uncomfortable and often even pain-producing sports device. The tight lacing ultimately preferred by most players hinders blood circulation especially in the ankle area and there is occasional considerable irritation of the front tendons in this area.

A lack of functionality is also expressed in the fact that with every use after a certain "running-in period" the skate boot usually has to be refilled. In addition, the transition from shin protection to ice skate boots is a problem for ice hockey players, the provisional solution of which is left to each player. The extended tongue prevents precise fixation of the lower end of the shin guard. Each player deals with this dilemma in his own way - often with fatal consequences for the protection of the player himself. The area beneath the shin protector, which is very effective in terms of protection technology, is particularly at risk from shots. And this is where the effective protection ends. There is only the tongue of the skate boot between the puck and the body. The tongue is padded, but there is no hard outer shell for impact protection. The protective function of the entire skate boot must be regarded as inadequate at all, with the exception of the stable toe cap.

Another design variant of skate boots is known, inter alia, from DE-OS 31 31 555 and US Pat. No. 4,282,659. In these known skate boots, a division into two is provided in a lower foot shell and an upper cuff, which are articulated to one another in the region of the ankle or somewhat below. The overall shape and dimensions of the boot are roughly the same as those of the leather boot. The two parts are made of plastic and form the outer one Bowl. The foot of the user is taken up by a padded inner shoe, which ensures the adaptation of the foot within the relatively hard plastic shell. This inner shoe is in one piece and corresponds in its outer dimensions to the shape of the outer shell. The tongue to underlay the lacing extends from the tip of the foot to the top of the lacing, just like with a leather ice skate.

These known embodiments differ structurally from leather sled shoe boots, above all in the articulated connection of shoe and cuff, which is intended to support mobility in the ankle. This would actually be the case if the tight lacing over the continuous tongue, as in leather skate boots, did not mean that the tongue had to be compressed when the ankle was flexed and stretched when it was stretched. In practice, the articulated connection thus brings only an insignificant improvement in terms of mobility. With regard to the lateral stability, the two-part plastic skate boot proves to be disadvantageous, since the padding of the inner shoe in the area of the ankle guarantees less precise stabilization. In addition, the padding impairs the precise transmission of power from the foot to the runner. The significantly better protective function of the plastic construction, especially in the ankle area, is, however, to be emphasized compared to the leather ice skate boot.

In summary, it can be said that both known basic construction variants take insufficient account of the main problems addressed.

It is therefore an object of the invention to provide a skate or roller skate boot for ice hockey or roller hockey which offers the user more lateral stability in the ankle and at the same time enables the angled movement of this ankle as freely as possible and which also provides optimal protection, particularly in the Ensures flexion area between instep and lower leg.

According to the invention, this object is achieved by the characterizing features of claim 1. The subclaims describe advantageous developments. Accordingly, the closure means for the foot shell and the cuff are completely independent of one another, the upper edge of the foot shell and the lower edge of the cuff being recessed on the instep side in such a way that an open flexion area is created. This results in a particularly good flexibility with respect to diffraction, since diffraction is possible until the two opposite edges meet. Furthermore, according to the invention, the cuff has two substantially flexurally rigid areas, one of which is designed as a cuff back part, which is articulated to the foot shell essentially at the height of the ankle and the other is designed as a cuff front part, which is fixed to the cuff back part by means of a closure, so that it allows entry into the boot from the front.

Finally, according to the invention, a protective part is provided to cover the open flex area, which consists of impact-resistant material, e.g. Made of sturdy plastic, the area to be covered is shaped so as to be pivotable about an axis transversely to the longitudinal direction of the shoe either at its end on the cuff side or opposite it and the free end of which is slidably held in contact with the respective shoe part.

It is advantageous if the protective part at the upper end is articulated substantially centrally on the front part of the cuff. As a result, the ankle protection part can e.g. to glide forward over the laces in the event of forward bends, as a result of which it is pivoted in relation to the front part of the cuff. In order to keep the ankle protector always snugly fitting on the upper side of the foot binding, longitudinally elastic elements between the front part of the cuff and the protective part are advantageously provided essentially off-center, which is particularly advantageous if on the lower edge of the front part of the cuff, in the respective vicinity of the side Outer end of the ankle protection part, an elastic band, e.g. a rubber band is attached, the other end of which is attached to an upstream zone of the protective part.

In a further embodiment, the protective part can be pivoted vertically in the vicinity of the shoe cap and be connected to it via longitudinally elastic elements, thereby ensuring the contact with the system. This protective part can consist of several parts that overlap in the longitudinal direction like roof tiles. When the foot is flexed or stretched, these overlapping parts will slide further one above the other or apart, but the flexion opening in particular is always kept closed in an impact-resistant manner.

It is particularly advantageous for increased flexibility when the foot shell in the heel area is cut out on its upper edge and the cuff back part on its lower edge to form a heel stretch opening. This stretching opening can advantageously be covered by a shape-adapted protective part in such a way that it is articulated on the respective part and locked over the other part. pivots and at the same time is held elastically in line, ensuring constant contact with the system. The protective part can be attached to the cuff back part (in the direction of the sole of the foot) or on the foot shell (in the direction of the knee) so that it can be pivoted vertically. In this case, elastic tapes running laterally on the inner side of the protective part can provide a corresponding sliding contact force.

Similarly, the articulation of the protective part in the heel area can be carried out advantageously. However, because the part is attached essentially vertically here and is exposed to possible impact effects coming from above, it is expedient to form the protrusion, which is formed on the cuff back part, in a roof-like manner. The protective part is seen in section in a fork guide, which is designed so far that the pivoting movement is not hindered. Since this protective part does not normally have to be removed in contrast to the ankle protection part, it makes sense to make the connection with the webbing emerging from the inside of the cuff back part on the inside of the heel protection part so that it is not exposed to external influences. However, the connection can be released with the help of a push-button or Velcro connection, so that it can be easily replaced if damaged. Instead of the fork guide, an articulated connection can be made in which the roller-shaped upper end of the protective part, which is designed as an articulated head, snaps into a corresponding joint socket on the cuff back part and can be secured by the above-mentioned belt strap.

The quick and tool-free interchangeability of the two protective parts also means that the elastic elements which hold the protective parts in contact with the foot shell in the movement of the foot shell and cuff must also be designed to be detachable. In the case of elastic bands, this should preferably be done with push buttons. Instead of elastic bands, a flat, elastic material could also be used. An inexpensive fastening option for this is if a stable bracket adapted to the shape of the protective part is fitted into the pulling end of the material and is hooked into corresponding flat hooks on both sides of the material, which are provided with securing lugs, so that the Bracket cannot slide out of the hook. Such a fastening can be provided on one side of the elastic material while it is, for example, permanently sewn on the opposite side, or it can be provided on both sides, so that the elastic material itself can also be replaced. It is also advantageous if the closure means are positively fixed transversely to the closing direction in the closed state of the sleeve. At least one tab can be formed as a component of the closure means on the front part of the cuff, which is held displaceably in guide grooves in the closure direction. In this way, an optimal vertical fixation of the cuff front part on the cuff back part is realized. The cuff front part can be completely detachable from the cuff back part. However, the front part of the cuff can also be hingedly attached to the back part of the cuff by swivel connecting elements known per se. As a result, when the cuff is opened, only the closure element is loosened, the closure flap is pulled out of the guides and opened to the front or to the side, with entry and exit being very convenient, especially since the separate, relatively short foot lacing can be released quickly and widely is evident.

Any known closure element such as e.g. Hook and snap fasteners or a webbing serve. The arrangement of a belt strap is particularly advantageous, since its shape is practically not significantly bulky and it is relatively impact-resistant. Furthermore, it is advantageous if the belt strap used as a cuff binding element is provided as a continuation of the guide closure flap and can be fastened to the cuff back part by means of a Velcro strap. It is particularly effective if a relatively long belt strap is used, which is additionally wrapped around the cuff once, whereby, in addition to the Velcro strap fastening on the middle part of the cuff back, at least one additional Velcro fastener is provided on the front part of the cuff and on the outside of the belt strap. whereby the security of attachment is significantly increased.

It is of particular advantage if the front part of the cuff is designed as a shin guard. The area that forms the shin guard can be releasably attached to the front part of the cuff. This avoids a shock-sensitive opening between the shin guard and the skate boot, and at the same time the one-piece shin guard skate boot which has a maximum protection and support effect is obtained by firmly coupling the shin guard to the upper edge of the skate boot.

In order to achieve a particularly good and secure fastening and support of the shin guard on the upper edge of the front part of the cuff, the lower edge of the Shin guard and the upper edge of the front part of the cuff are interlocking. For this purpose, for example in the area of the upper edge zone of the front part of the cuff, fitting parts, such as horizontally protruding guide and support elements, can be provided, for example triangular parts tapering to the top, pins or parallel springs which are provided with corresponding shape recesses on the lower edge of the shin guard. such as triangular recesses or vertical grooves, work together so that the corresponding horizontal and vertical stops allow for insertion with correspondingly easy positioning. The triangular shape is particularly advantageous here, since, apart from the large vertical support, it also has maximum insertion bevels, so that the precise positioning can be carried out very quickly and easily.

To connect the shin guard to the front part of the cuff, it is particularly advantageous if at least one, preferably two or three connecting straps are provided on the lower edge of the shin guard, which can be fastened to the front part of the cuff by means of known closure elements, preferably Velcro fasteners. This has a particularly advantageous effect if these connecting straps are designed so that they lead downwards so that they are held or secured and stabilized against loosening by loosening a long fastening strap of the front part of the cuff. When the connecting straps are designed with Velcro fasteners as connection elements, a particularly firm connection can be achieved by additionally holding the Z-strap webbing, which is guided over the connecting straps, in the front zones of the cuffs between the connecting straps via Velcro fasteners on the front part of the cuff.

With regard to the connection between the front part of the cuff and the shin guard, it is advantageous if the register stop is adjustable in height. This can be achieved if the register stop is located on a separate plate which conforms to the shape of the cuff front part and which can preferably be inserted into different positions with self-locking pins in a corresponding matrix of bores in the cuff front part. As a result, the user has the possibility of carrying out a fine positioning of the shin guard adapted to his needs.

It is also particularly advantageous if the padding on the inside of the foot shell, cuff and front part of the cuff is provided integrally and separately on the respective part and is shaped in such a way that it bends and stretches the ankle. prevents allow. As a result, there is no compression or stretching of upholstery parts, which ensures optimal freedom of movement.

In a special further embodiment, the skate boot according to the invention can be designed such that the front part of the cuff is integrally formed on the lower edge of the shin guard known per se. This means that the shin guard is a solid, integral part of the front part of the cuff and thus of the cuff as a whole, with additional optimal lateral tab flaps and closures, e.g. Fast fastenings or fastener straps wrapped around the entire outer circumference of the cuff can be achieved in a secure and maximally stable manner.

A "quick attachment" can be achieved if the cuff closure or the shin guard on the back part of the cuff is inserted or removed in horizontal guides and in each case laterally by means of snap closures leading as far back as possible or on the inside by e.g. In and on the outside by e.g. flat clamps can be fixed in position in just a few simple steps.

According to the invention, a mobility corresponding to the anatomy of the ankle is thus achieved with respect to flexion and extension with simultaneous lateral stabilization, and complete protection is also ensured. The essential requirements of ice skate boots for ice hockey are thus optimally met. These claims result both from the player's specific movement sequence for ice hockey and from the risk of injury to the player.

The ice hockey player's running technique, which is considered to be optimal, requires an approximately right-angled flexion of the hip and knee joint in the gliding phase in order to be able to accelerate from it again and again and to keep the center of gravity relatively low for better maneuverability and better stability. Accordingly, the ankle should be able to move freely when flexed. This is made possible according to the invention by the articulated connection of the foot shell and the cuff with a short lacing and a short tongue and a corresponding spacing of the cuff from the upper edge of the tongue or lacing. Furthermore, the best possible extension in the ankle is required in order to release an additional and last forward impulse from the tip of the foot against the ice in the rejection phase of the skate step after the extension in the knee and hip joint, which is ensured by the heel-side extension opening between the foot shell and the cuff back part. It can be of decisive advantage for the running effectiveness of the user if the skate or roller skate boot is in principle permanently stretched by tension spring force. This can be explained as follows: Each ice skating step takes place in such a way that the pushing foot is brought back as far forward as possible after the kick and is bent so far that the skid can evenly touch the ice. In the next phase, this foot is pushed obliquely outwards relative to the direction of travel, which essentially generates the propulsion. In this propulsion phase, the foot is brought out of the initial, as strong as possible deflection into a first right-angled position, in order then to achieve the greatest possible extension in the final phase of the repulsion path. That means maximum propulsion under normal circumstances. If the skate boot is now permanently stretched by a tension spring force, this means that the foot must be raised against the tension spring resistance by the flexion muscle of the ankle joint each time the skid is placed on the ice. A comparable resistance must also be overcome in conventional skate boots due to the high lacing, but the energy used is lost. If, on the other hand, a tension spring is tensioned, most of the energy used is stored. This energy is ideally discharged in the further movement of the skate step, when the ankle is slowly stretched and in the last push-off phase stretches completely.

The present concept of the new ice skate boot with its complete extension and flexion option is suitable for making such an energy store look ideal. A refinement of this idea means that the tension spring resistance can be exchanged and is available to the user in different hardnesses. The user has the option of starting with a slight tension spring resistance and building up his ankle flexor muscle in a targeted manner until he can gradually use tighter tension spring resistances which store more energy and give more propulsion.

As a practical example of a tension spring resistance, an elastic band made of rubber or fabric can preferably be used, which is fixed in the heel area of the foot shell with the aid of push buttons and also in the upper area of the inner cuff back part. It is advantageous if the upper connection point is adjustable in height, which can be achieved with a vertical row of push button counterparts on the inner cuff back wall. The user has the possibility lent to fine-tune the spring resistance according to his needs.

An efficient running technique at the same time requires a straight alignment of the ankle, seen from the front, exactly in the line of force in order to bring the push-off energy from the hip and the knee onto the ice without loss. Because the skate blade represents an unnatural extension of the foot below the ankle and, moreover, the contact surface of the blade is narrow, the muscles and ligaments around the ankle are unable to do so, for example for the duration of a game and, above all, under constant pressure through the opponent to maintain the straight line of force. As already mentioned, in the case of the skate boot according to the invention, the articulated cuff is stably and comfortably closed around the lower leg far above the ankle. The shin guard, which is firmly coupled to the front part of the cuff, acts as an extension of the cuff to just below the knee bend, where it is connected to the lower leg in a known manner by means of a band and thus offers a very long lever for stabilizing the ankle.

A precise alignment of the ankle and knee joint in the line of force not only allows the best possible conversion of the energy used into actual movement, but also protects the cartilage of the joints. This means that the cartilage is evenly loaded and the risk of cartilage crushing is low. This particularly affects the sensitive meniscus of the knee joint; because a lateral buckling of the ankle also means a lateral kink deviating from the line of force for the knee joint and consequently a unilateral loading of the cartilage with the known consequences.

Basically, however, the lateral stabilization of the ankle should not be completely rigid. It is therefore necessary to use the inner edges of the runners more quickly in the event of a quick start, ie at the moment of pushing off the runners are brought to the ice at a somewhat more acute angle than the line between the knees and the inner runners. This desired deviation is in a range of only a few degrees. Lateral mobility beyond this already means destabilizing the ankle. The task is therefore to enclose the user's foot and lower leg in such a way that the ankle is stabilized outside a defined angular range, mobility within this range with a tendency towards self-centering is made possible. The tightness of self-centering should ideally be adjustable so that it can can be selected by users with different anatomical conditions and depending on the training condition and personal taste.

This can be achieved by the type of padding in the back part of the cuff. A comparatively soft padding that lies against the sides of the lower leg within the closed cuff construction will allow more lateral mobility with less tight self-centering of the ankle than a harder padding. It is advantageous if this adaptation can be carried out quickly, accurately and without tools. It is therefore provided that the cuff padding is divided into several elements, so that cuff padding is variable in itself. The individual elements are fastened to the inside of the back part of the cuff with the help of snap fasteners, Velcro fasteners, profiles and counter profiles or similar connecting elements.

A further advantageous possibility for the quick and user-friendly exchangeability of the upholstery consists in that a carrier element in the manner of a pocket belt accommodates the individual cushion elements, which are variable in consistency and thickness, and in that this carrier element then into the cuff back part with the aid of those already mentioned Fasteners is used. This construction also offers the possibility of removing and washing the carrier element if necessary.

A second possibility of producing variable lateral mobility in the ankle, if desired, is that such mobility is made possible in the rotary joints themselves. This is achieved in that the bore for receiving the pivot pin in the cuff back part is designed as a vertical elongated hole in which the pivot pin fixed in position on the foot shell can move. In this way, a basic lateral mobility in the ankle is possible. The further the elongated holes are made, the greater the mobility. A spring-damped centering in the ideal line of force from the knee to the skid is achieved in that the evacuation spaces of the pivot pin in the elongated hole are in principle filled with resilient elements. This can preferably be solved in such a way that an S-shaped metal or plastic spring is inserted into a recess of the pivot pin, the upper turn of the "S" filling the upper escape space of the elongated hole and the lower turn filling the lower escape space. Different types of springs can now be used. The exchange is carried out in a simple manner by removing the cover cap on the pivot bolt, which in itself holds the pivot joint together, and removing the spring. and a new spring is inserted. The cover cap is then replaced. The cover cap can preferably be attached to the pivot pin with a threaded screw.

A final essential requirement on the part of ice hockey for suitable equipment in general is an adequate protective function. This is particularly the case with the invention, since there is continuous protection from the tip of the foot to the knee. The area from the running instep up to the crook of the foot is protected by a protective part that glides with the movement. The shin guard is overlapped and coupled to the front part of the cuff and offers continuous protection for the lower leg as well. The necessary open area at the level of the Achilles tendon is also covered by a protective part that glides with the movement. The two protective parts over the crook of the foot and the Achilles tendon are always guided closely to the foot shell by elastic bands, so that there are no places open to impact due to flexion or extension of the ankle.

The construction of the skate boot alone and the connection of the skate boot and shin guard to a functional unit also result in clear advantages over conventional practice in terms of comfort and "user friendliness". So before putting on the skate boot, the laces no longer have to be pulled out of the upper eyelets and evenly distributed over the lower laces. The lacing is practically a shoe lacing. Entry and lacing are correspondingly easy for the user. In contrast to conventional ice skate boots, there is no longer a need to lace up so tightly, since the stable hold for the foot is achieved by the high edging of the lower lower leg by the cuff back part and cuff front part. So there are no more uncomfortable to painful constrictions in the area of the foot arch. This sensitive area is exposed and is only covered by a protective part on a higher level for the purpose of protection.

After the foot shell is laced, the cuff front part, which is initially folded away, is folded into the intended position and the closure flap of the anatomically padded cuff front part is inserted into the guide groove of the cuff back part and fixed by means of a webbing strap and Velcro fastener. The locking tension does not have to be high, since the levers are long up to the ankle due to the high position of the binding and the stabilizing effect is therefore enormous. Overall, it can be said that the Skate boots according to the invention comfortably enclose the foot of the user without generating increased pressure at the points known in conventional skate boots. In addition, the entry and the complete fixation is easier, more convenient and can be accomplished in a shorter time than with these.

Finally, the shin guard is placed on the form-fitting / register stop of the front part of the cuff and fastened to the front part of the cuff with Velcro fasteners and then secured by a further turn of the fastening belt and an additional Velcro element. This means that the shin guard is always fixed in the optimal position and cannot, as in conventional practice, twist on the lower leg or shift in height. The previous provisional fastening of the shin guard is no longer necessary.

Furthermore, it can be particularly advantageous for roller skate boots if, above all, the protective parts above the arch of the foot and the Achilles tendon are provided with ventilation holes.

In addition, it is possible and, apart from cost reasons, also desirable to make the protective parts, the cuff and the shin guard from modern materials such as Manufacture carbon fiber. This would mean a worthwhile weight saving and even higher safety for top athletes.

16 shows the cuff front part with a triangular stop from the direction of travel, FIG. 17 shows the section D - D from FIG. 16 and FIG. 18 shows a side view of the ice skate boot according to FIG. 2 in the flexed state, with the cuff back part cut open, heel protection part and partial foot shell. The skate boot shown in Fig. 1 has a foot shell 1, on the underside of which a skate blade 16, e.g. is fixed by screws or rivets.

The height of the foot shell 1 is approximately like a low shoe that closes off slightly above ankle height. It has on its instep side a fastener 15 for lacing which, because of the short shoe shape, only spans the foot over a short length.

The skate boot also has an essentially tubular cuff 2, which is pulled at ankle height by lateral ear parts 6 over the outer sides of the foot shell 1 and is pivotally connected to it via a horizontal swivel 5 in the direction of travel. A flexure opening 17 is formed between the lower edge 9 of the cuff and the upper edge = foot shell 11. The cuff 2 consists essentially of two half-cylinder parts, namely a cuff back part 3 and a cuff front part 4, which are slightly overlapping at least on one side and are detachably connected to one another via at least one side closure element 7. On the side of the cuff, instead of the closure elements 7 from FIG. 1, swiveling hinges which cannot be seen and which allow the front part 4 of the cuff to be opened can be provided.

At the lower end of the front part 4 of the cuff, a protective part 8 is fastened in the middle, essentially pivotably, via a hinge element or a pivot point 10. This protective part 8 is tongue-shaped or quadrilateral and at the same time adapted to shape from impact-resistant material, preferably made of plastic, and is held on its side wing parts by means of a longitudinally elastic element 12, the upper end 13 of which is on the lateral outer edge of the cuff front part 4 and the lower end 14 of which advanced inner surface of the protective part 8 is fixed, whereby this protective part 8 is held against the closing means 15.

In the skate boot shown in FIG. 2, the foot shell 1 is cut deeper at its rear upper heel edge in the direction of the heel, while the cuff back part 3 has a corresponding lower edge cutout, which form a stretching opening 21 between them. This stretching opening 21 is covered by a protective part 22 which is made of impact-resistant material and conforms to the shape and is easily pivotable in a vertical plane by means of a pivot hinge 23 on the cuff back part 3 and is kept slightly pressed between the cuff back part 3 and the protective part 22 by means of longitudinally elastic elements 24.

The cuff front part 4 has on its outside a locking tab 25, the horizontal guide edges of which are guided horizontally displaceably in guide grooves 26, which at the same time form a vertical support. At the outer end of the closure tab 25, a closure strap 27 is provided for fastening to the cuff back part 3 by means of at least one Velcro closure. This fastener strap 27 can have a short embodiment and only enclose the cuff back part 3 for a short time. The closure strap 27 can, however, also be designed in a long form, wherein a plurality of Velcro fastening attachment points can be provided on the cuff back part 3 and cuff front part 4, at least two each on the cuff parts and on the belt itself.

The shin guard 18 is connected to the top of the cuff front part 4 via connecting straps 28. These tabs 28 can be Keys or pins and eyes form the necessary vertical connection. In this exemplary embodiment, triangular stops 30 are provided as register stops, as can be seen or described more precisely or in connection with the development view according to FIGS. 7 and 8.

The skate boot shown in FIG. 3 is constructed essentially in the same way as that of FIG. 1, with a known shin guard on the front part 4 of the cuff, which has its own padding 46 and can be secured in a known manner via a belt 44 on the leg 18 is integrally formed.

FIG. 4 shows the longitudinal section through the skate boot according to FIG. 2, the foot being in the normal position. The flexion opening 17 and the stretching opening 21 are clearly visible under the protective parts 8, 22 covering them.

Fig. 5 shows the view like Fig. 4 with the foot bent. The space of the bend opening 17 is narrowed and the protective part 8 slides forward over the closure means 15, while the protective part 22 still covers the opening 21 which opens further.

Fig. 6 shows the same view as Fig. 4 and Fig. 5 with the foot extended. The stretching opening 21 narrows, the protective part 22 slides down on the heel side of the foot shell 1, while the further opening foot flexion opening 17 is still covered by the protective part 8.

7 and 8 show the partial development and a section A - A through it, the shin guard attachment according to FIG. 2.

The triangular stops 30 are vertically protruding from the outer surface of the cuff front part 4 and have corresponding triangular undercuts 45. At the same time, corresponding V-recesses 31 are provided on the lower edge of the shin guard 18, which engage in the undercuts 45 of the stops, so that the shin guard is also secured against radial lifting off. By guiding the belt 27 and firmly fitting it over at least a portion of the connecting straps 28, these are well protected against unintentional lifting.

In the embodiment of the shin guard attachment shown in FIGS. 9 and 10, the central register stop is designed as a parallel spring 32 and the outer stops as pins 33, while the form-fitting recesses in the lower edge of the shin guard 18 are vertical grooves 34.

Between the register stops 29, 30, 32, 33, the connecting straps 28 are provided for fixing the shin guard 18 to the front part 4 of the cuff Connecting tabs 28 can be connected to the front cuff part 4 via Velcro fasteners 42 or eyelets and pins 35 or hook-engaging parts. To hold it securely, the long fastening strap 27 is wrapped around the cuff at least once so that it rests firmly over the connecting straps 28, with the arrangement of a further Velcro fastening element 36 between the fastening flaps and additional Velcro fastening elements 43 on the ends of the flaps 28 Holding effect of the belt 27 is increased.

In turn, the cushion elements 47, 48, 49 are fixed independently of one another on this carrier element 50 or are detachably connected with the aid of connecting elements such as Velcro fasteners or push buttons.

12 shows the elements of the cuff back part 3 and foot shell 1 which overlap in the joint area. The cover cap 55 is shown transparently and gives a clear view of the vertical slot 52 in the cuff back part 3. The pivot pin 53, which is rotatably fixed to the foot shell 1, engages in this slot 52. The pivot pin 53 can move vertically in the slot 52. This movement is damped up and down by an S-shaped metal spring 54. This S-shaped metal spring 54 lies in a corresponding recess in the pivot pin 53 and is thus fixed in position but interchangeable.

FIG. 13 shows the section C - C from FIG. 12. It can be seen how the pivot pin 53 is held by a disc-shaped widening on the inside of the foot shell 1 and can thereby rotate with the joint movement. The closure of the joint connection is formed by the cover cap 55, which is fixed in the center of the pivot pin 53 by means of a fastening screw 56. The screw head of the fastening screw 56 is countersunk in the cover cap 55.

The connection between the cuff back part 3 and the heel protection part 22 is shown in section in FIG. 14. The protective part 22 has a roller-shaped shape at the upper end, which, as a joint head 59, engages in a corresponding joint socket 60 which is molded onto the cuff back part 3. A belt strap 58, which is cast in the cuff back part 3, serves to additionally secure the position. There is a Velcro strip thereon which, with a counterpart attached to the heel protection part 22, results in a Velcro fastener 57. 15 shows the section through the protective part 8 and the lower part of the cuff front part 4. The protective part 8 lies in a right-angled inner edge which is formed from the cuff front part 4 and a projection 61 formed thereon. In this position, the ankle protection part is held by a webbing 62, which emerges from the inner edge. A Velcro fastener 63 between this webbing 62 and the protective part 8 forms a releasable connection. At the end of the ankle protector part 8 pointing towards the tip of the foot, hooks 65 are formed on the underside with a securing nose 66, one of which can be seen in section. A bracket 67 lying transversely to the direction of the foot engages in this hook 65. Between the hooks the bracket 67 is bordered by a longitudinally elastic element 64 which is fixed at the other end to the cuff front part 4.

16 shows the cuff front part 4 seen from the direction of the toe. Placed thereon is a plate 68 with the integrally formed triangular stop 30. The plate 68 has four self-locking plug-in bolts 69 which are inserted into the corresponding holes 70 in the front part 4 of the collar. Fig. 17 shows the section D - D from FigJ6.

The entire side view of the skate boot is shown in FIG. 18. The tube consisting of the cuff back part 3 and the front cuff part 4 is steered forward in the swivel joint 5. The cut cuff back part 3 allows a view of a longitudinally elastic element 71 which is clamped between the cuff back part 3 and the foot shell 1. A vertical row of push buttons 72 is embedded in the cuff back part 3. The longitudinally elastic element 71 is buttoned into one of these push buttons 72. The other end of the longitudinally elastic element 71 is hooked into a hook 73 of the foot shell 1.
