Abstract

A roller skate with a single row of rollers to be used with sport or off-the-road shoes has at least two running rollers (3a, 3b, 3c, 3d, 103a, 103b, 103c, 103d, 203a, 203b, 203c, 203d, 303a, 303b, 303c, 303d, 403a, 403b, 403c, 403d) arranged in a frame (2, 102, 202, 302, 402). The shoe of the roller skater may be fastened on a sole supporting plate (5, 105, 205, 305, 405) secured to this frame (2, 102, 202, 302, 402). In order to align the running rollers (3a, 3b, 3c, 3d, 103a, 103b, 103c, 103d, 203a, 203b, 203c, 203d, 303a, 303b, 303c, 303d, 403a, 403b, 403c, 403d), the frame (2, 102, 202, 302, 402) may swivel around an axis (A) substantially normal to the sole supporting plate (5, 105, 205, 305, 405) and may be fixed together with the sole supporting plate (5, 105, 205, 305, 405).

Description

Single track roller skate

The present invention relates to a single-track roller skate for use with a sports or all-round shoe, with at least two rollers arranged in a frame and with a sole support plate attached to this frame. To fix the roller skater, a lower leg support can be provided which has at least one support protruding upwards from the side of the sole plate or in the heel area, on which a fastening means which at least partially encompasses the lower leg is provided, or at least one lateral protruding from the sole plate Stop may be provided on which the skater's shoe can be fixed.

A roller skate of the above type is e.g. from FR-PS 784 617. In this roller skate, two or three rollers are arranged in a frame which is rigidly connected to a support plate for a shoe. A lower leg support protrudes laterally from this support plate, which is formed from two sections which are articulated to one another about a transverse axis, a sleeve which can be placed on the lower leg being fixed to the upper section. Movable and rigid holding clips are also provided on the support plate, by means of which a sole of a shoe provided with opposing holding elements can be attached to the support plate. A roller skate of this type is intended for the roller skater to step into the roller skate with street shoes or ordinary sports shoes in order to roller skate. Since different types of shoes have different widths, there is the problem with this known roller skate, in particular due to the one-sided lower leg support, that the rollers are not exactly centered and are not always aligned in the running direction. Another disadvantage of this known roller skate is that the lower leg is subjected to extremely heavy loads such as e.g. occur when jumping or running figures, due to the one-sided cuff suspension is not kept sufficiently stable.

From US-PS 4418 929 a single-track roller skate has become known, in which attachments for a shaft support, an instep support and a support in the ball or toe area are attached to a frame provided with rollers. The roller skate, which has a support on both sides for a shoe or the lower leg of the roller skater, is designed to be width-adjustable, the two-part add-on parts being fastened to the frame via transverse slots. On the basis of these transverse slots there is also a Possibly required alignment of the rollers possible, however, four screws must be loosened and tightened for each attachment and the attachments must be aligned in alignment with one another in order to be able to carry out such an alignment. Due to the mutual support, this roller skate can also be suitable for heavy loads. However, a width adjustment of this roller skate in the shaft area is very complex.

FR-A-2440208 furthermore shows a skateboard in which a base plate which is rotatable by 90 ° is arranged above the base plate. The purpose of this base plate is to be seen in that the skateboarder looks in the direction of travel when the base plate is rotated by 90 ° with respect to the base plate, and therefore in this position of the base plate an improved stability of the position of the driver is made possible. Such a procedure is not necessary for a roller skate, since the roller skater is already looking in the direction of travel and is in a sufficiently stable position.

Furthermore, a gymnastics device has become known from US Pat. No. 5,062,630, in which gymnastic exercises can be carried out in a handstand on a frame with four wheels, three of which are arranged at the corner points of an equilateral triangle and one in the center of this triangle. To improve the sense of balance of the gymnast, it is proposed to attach a plate which can be rotated about a vertical axis and pivoted sideways to the frame. Such a device is also in no way suitable for use on a roller skate.

Features of known one- or two-track roller skates are also evident, inter alia, from the publications AT-PS-153 259, US-PS-1 529 967, DE-PS-857 006 and GB-A-2 130 896.

It is an object of the invention to enable the rollers to be aligned as simply and quickly as possible with respect to the sole support plate in the case of a single-track roller skate of the type mentioned at the beginning. In particular, it is an object of the invention to improve a roller skate with at least one-sided lower leg support or a lateral stop for the roller skate so that it can be run with shoes of any width and length.

Starting from the roller skate mentioned at the outset, this object is advantageously achieved in that the frame is connected to the sole support plate so as to be pivotable and lockable about an axis which is essentially normal to the sole support plate. This measure enables a particularly simple and rapid alignment of the frame with the sole support plate, so that the roller skate can be easily matched to any shoe of a roller skater. With such a pivoting of the frame with respect to the sole support plate, anatomical misalignments of the foot can be corrected simply and effectively.

In a preferred embodiment of a roller skate according to the invention, the axis is arranged in the heel region of the roller skate in the region of the longitudinal center plane. This configuration is particularly advantageous since the width of shoes in the heel area has fewer differences than in the ball area and the frame can therefore remain essentially stationary in the heel area. In such an embodiment, a lockable guide device for the frame is advantageously provided in the ball area of the roller skate, by means of which the frame is guided essentially transversely to the longitudinal center plane when pivoted with respect to the sole support plate.

In one exemplary embodiment, the guide device has a bolt which is guided in a slot which is formed essentially transversely to the longitudinal center plane. In a further exemplary embodiment, the guide device has a spring-loaded and lockable clamping jaws which are guided in a slot transversely to the longitudinal center plane. In a further exemplary embodiment, the guide device has a latching mechanism which enables a plurality of different latching positions with respect to the longitudinal center plane. All preferred embodiments have in common that the guide device for aligning the frame to the sole support plate can also be actuated in an advantageous manner when the roller skate is placed on the skater's shoe, since it is accessible either from the side or from the front. As a result, the direction of the rollers can be adjusted exactly to the skater's just worn shoe without having to remove the roller skate from the shoe. This setting can be carried out particularly quickly and by the roller skater himself. For example, the manufacturer recommends aligning the direction of the casters with the direction of the second toe from the inside.

In a practical and orthopedically mature embodiment of a roller skate according to the invention, an instep support is provided on the sole plate, which has a tensionable band essentially guided over the instep, the band having a front and a rear section in the area of the inside of the shoe and the front section in the ball area is connected to the sole support plate and the rear section in the ankle area to the sole support plate and / or the lateral support and the front and the front led over the instep and the front led over the instep merge rear section into one another and are connected to a traction device, which is connected in the heel area of the roller skate on the outside of the shoe to the sole support plate or the lateral support and has a tensioning device there.

Furthermore, it is advantageous in practice if, in the embodiment with an upwardly projecting side or rear support, the fastening means is a closable sleeve which is pivotable on the upper end portion of the side support and, if appropriate, is displaceable in the longitudinal direction against a restoring force. Furthermore, the support on the sole support plate can be arranged in a side-adjustable manner in order to enable the sports device to be better adapted to the anatomical conditions of the skater.

In a variant which can be produced at low cost, the lateral or rear support is formed in one piece with the soleplate and is made of a plastic, e.g. fiber-reinforced polycarbonate or polyamide. In an alternative embodiment variant, the support is detachably arranged on the soleplate, both the soleplate and the support made of a light metal, e.g. Aluminum. This variant has the great advantage that the roller skate can be dismantled after use and can therefore be transported and stored in a particularly space-saving manner. Furthermore, a more stable and firmer construction is made possible, which is particularly suitable for athletic runners.

Starting from a roller skate according to the invention with a lateral support, it can advantageously be provided that the laterally upwardly extending support has a bracket which is guided essentially around half the lower leg, and on the other hand in that the bracket on the opposite side support Side is provided with a support which is rigidly connected to the sole support plate in the heel area. This measure enables a particularly simple and effective reinforcement of the lower leg support. This reinforcement advantageously does not limit the width or length of shoes to be used. This means that the roller skater can still use his roller skate with any shoes without having to make any width, length or shaft adjustments. For this reason, a roller skate of this type can be produced inexpensively. The special support of the bracket also does not hinder getting in and out of the roller skate.

Furthermore, in an embodiment with a lateral support, it is advantageous if the lateral support is arranged on the outside of the shoe, since, due to the movement sequence when exercising, better support can be provided on the lower leg of the roller skater. In an advantageous embodiment of the roller skate according to the invention with the lateral support, the latter is also fork-shaped in the region below the ankle, an arm which is guided forward in the region of the metatarsal base and an arm which is guided back in the region of the heel bone is connected to the sole support plate. Furthermore, in this embodiment, the support arranged on the inside of the shoe is guided essentially behind the ankle in the heel region, where it is connected to the arm of the lateral support leading to the rear and / or to the sole support plate. In this embodiment, the shoe of the roller skater is advantageously supported on the outside on the side of the front arm and on the back on the rear arm of the side support, whereas the shoe is free on the inside, so that despite a particularly stable lower leg support, it is also sufficiently large Scope for different width shoes is created.

In the embodiment with a lateral stop, it has proven to be advantageous if the lateral stop is arranged on the outside of the shoe. Furthermore, this embodiment can be improved if, in the heel area of the sole support plate, a rear stop projecting upwards is provided for the shoe of the roller skater. In an advantageous embodiment, the lateral stop and the rear stop in the ankle area are connected to one another to form a one-piece lateral support for the skater's ankle. For cost-effective production, the side and rear stops or the one-piece support are formed in one piece with the soleplate and are made of a plastic or a light metal.

For now, reference is made to FIG. 1, in which an embodiment of a single-track roller skate 1 according to the invention is shown in a side view. This roller skate 1 has a frame 2, in which four rollers 3a, 3b, 3c, 3d are arranged one behind the other in the longitudinal direction so as to be rotatable about a transverse axis. In the illustrated embodiment, a brake stub 4 is also provided at the rear end of the frame 2.

The frame 2 is connected with the aid of fastening and guide means, not shown here, to a sole support plate 5, the surface of which is essentially flat and is optionally provided with a friction-increasing support. In the present exemplary embodiment, a one-sided lower leg support 6 is provided on the inside of the shoe, which has a lateral support 7 which projects upwards from the sole support plate and on which a closable sleeve 8 is mounted in the upper end section. The cuff 8 is padded on its inner side facing the lower leg and is applied to the lower leg of the roller skater by means of a suitable closure 9. The support 7 is fork-shaped in the area of the sole support plate and, viewed from the side, essentially has the shape of an upside-down Y, the arms 7a, 7b of which in the present exemplary embodiment are integral with the area of the shoe center and in the heel area Sole support plate 5 are connected. Further details regarding the arrangement of the lateral support 7 on the sole plate 5 are explained in more detail below with reference to FIG. 15. In the area below the cuff 8, the support 7 may be elastic formed so that a limited forward and backward movement or lateral movement of the lower leg is possible. In another exemplary embodiment, not shown here, the support can be provided with a joint in the area between the sole support plate and the cuff, which allows the cuff to be pivoted forwards and backwards about a transverse axis.

In the heel area of the roller skate 1 there is further provided a support 10 to the rear, which can optionally be formed in one piece with the support 7; and has a rear section 13, the front section 12 in the ball area being connected to the sole support plate 5 and the rear section 13 in the ankle area being connected to the sole support plate 5, and the front section 12 guided rearward over the instep and the forward section over the instep the rear section 13 of the band 11 merge into one another and are connected to a traction means 14 which is connected to the sole plate 5 in the ankle region of the roller skate on the outside of the roller skate. The traction means 14 has a suitable tensioning device 15, by means of which the band 11 can be tensioned, loosened or fixed. The rear section 13 of the band 11 is also connected to the support 10 and can optionally be a traction means, such as a band, and a tensioning device, e.g. have a Velcro fastener to apply the support 10 exactly to the heel portion of the skater.

In Figures 2, 3 and 4, a sole support plate 5 of a roller skate according to the invention is shown in a plan view, a cross section and a detailed view.

In the heel section of the roller skate, the frame 2 is articulated on this sole support plate 5 about an axis A oriented essentially normal to the sole support plate 5. Such articulation can be done by any known means, e.g. a rotatably mounted pin. The axis A is preferably arranged in the longitudinal center plane ε of the roller skate.

In the bale section B of the roller skate, a lockable guide device 16 is provided for the frame 2, by means of which the frame 2 is guided transversely to the longitudinal center plane ε of the roller skate when it is pivoted with respect to the sole support plate 5. In the exemplary embodiment shown, the guide device 16 has a vertical bolt 17 connected to the frame 2, which is guided in a slot 18 arranged transversely to the longitudinal center plane ε in the sole support plate. Both the bolt 17 and the contactor 18 are mushroom-shaped at their upper ends to guide the slide to improve and hold the frame 2 in the vertical direction on the sole support plate 5. In the exemplary embodiment shown, the bolt 17 is rigidly connected to the frame 2 by means of a screw 19. Through the lateral ends of the slot 18, the pivoting of the frame 2 with respect to the sole support plate 5 is limited to a certain angle. If the distance between the axis A and the guide device 16 is small, the slot 18 can, in an embodiment not shown here, be curved around the axis A, preferably circular.

The slot 18 is further extended on both sides by means of transverse bores 20, 21 aligned transversely to the longitudinal center plane ε, in which a screw spindle 22 is arranged, which cooperates with the bolt 17 in such a way that the bolt 17 rotates along the screw spindle 22 Slot 18 is performed. For this purpose, the screw spindle 22 is mounted in a threaded bore of the bolt 17 which is oriented transversely to the longitudinal center plane ε. At the outer ends of the transverse bore 20 21 5 recesses 23, 24 are provided in the sole support plate. An actuatable head part 25 of the screw spindle 22 is rotatably supported in a recess 24, whereas an end nut 26 of the screw spindle 22 is etched away in the other recess 23 against the sole support plate 5. By means of this arrangement, the screw spindle 22 can be rotated when the end nut 23 is loosened and non-rotatably held in the sole plate 5 when the end nut 23 is tightened.

FIGS. 5 and 6 show a further exemplary embodiment of a sole support plate 5 in a top view and a cross section. In this embodiment, the guide device 16 has a latching mechanism which enables a plurality of different latching positions for the frame 2 with respect to the longitudinal center plane ε. In the exemplary embodiment shown, this locking mechanism has a spring-loaded pin 27, which is mounted horizontally in the sole support plate 5 and aligned along the longitudinal central plane ε, and which can snap into a plurality of bores 28a, 28b, 28c arranged at a distance from one another transversely to the longitudinal central plane ε, said longitudinally aligned bores 28a, 28b, 28c are provided in a guide block 29 rigidly connected to the frame 2, which is guided in a slot 30 of the sole support plate 5 aligned transversely to the longitudinal center plane ε. The rigid connection between the frame 2 and the guide block is realized in the present exemplary embodiment by a vertical bolt 31 which is guided in a guide slot 32 which is arranged parallel to the slot 30 but is of a smaller dimension.

At the front end of the pin 27, a handle 33 is also provided in or immediately below the sole support plate 5, by means of which the pin 27 counteracts Spring force can be released from a bore 28a, 28b, 28c in order to be able to pivot the frame 2 with respect to the sole support plate 5. After the handle 33 has been released, the pin 27 automatically engages in the next bore 28a, 28b, 28c in the course of the pivoting movement.

FIG. 7 shows a section of the sole support plate 5 of a roller skate according to the invention, in which a further embodiment variant of a guide device 16 is shown. This guide device 16 has a spring-loaded jaws 35, which is guided in a slot 34 transversely to the longitudinal center plane ε and can be loaded against an end face of the slot 34 by means of an eccentric 36. As seen from above, the slot is circular, the axis A preferably running through the center of the associated circle. The eccentric 36 in the present exemplary embodiment is arranged in the sole support plate 5 so as to be pivotable about a vertical axis and has a horizontal actuating lever 37 which is arranged in such a way that it is in the open position of the eccentric 36, in which the clamping jaws 35 are assigned Front surface is released, is directed forward in the longitudinal direction of the frame 2 and thus indicates the alignment of the rollers. In the closed position, in which the clamping jaw 35 is pressed by the eccentric 36 against the end face of the slot 34, the actuating lever 37 is arranged sunk in or immediately below the sole support plate 5.

Figures 8 and 9 show the special articulation of the cuff 8 on the side support 7 in a side view and a vertical section. A curved lateral slot 38 is arranged in the upper end section of the support 7. In this slot 38, a cross bolt 39 connected to the sleeve 8 is rotatable and is longitudinally displaceable against an elastic element. In the exemplary embodiment shown, this elastic element is formed by two springs 40, 41, each of which is supported on the transverse bolt 37 and at its other end against the associated end of the slot 38. The possible forms of movement of the cuff 8, which result from a superposition of a translational and a rotational movement, are shown schematically in FIG. 8.

FIG. 10 shows a further embodiment of the special cuff linkage, in which the slot 38 is made horizontally and straight, in contrast to the above. The forms of movement of the cuff 8 are also shown schematically in FIG.

FIG. 11 shows an embodiment variant of the roller skate according to the invention from FIG. 2. In addition, the position of axis A can be adjusted laterally in this variant. Such an adjustment may be necessary if the shoe width changes significantly in the heel area. In the variant shown, the adjustment is constructed in the same way as the guide device 16 of FIGS. 2 to 4. However, any other suitable device, for example also one of the guide devices according to FIGS. 5 to 7, can also be used as the adjustment mechanism for the axis A.

FIG. 12 shows a further exemplary embodiment in which the lateral support 7 of the lower leg support 6 is laterally adjustable in the region of its fork arm 7a. FIG. 12 shows a neutral middle position (strongly outlined) and an outer or inner end position (hatched). Such a lateral adjustment of the arm 7a can alternatively take place to a lateral adjustment of the axis A according to FIG. 11.

FIGS. 13 and 14 show a side view of the front end section of a roller skate according to the invention, a protective cap 42 for the toe region being shown in FIG. 13. Such a protective cap 42 is particularly advantageous when the roller skater is wearing soft shoes or is driving barefoot. In contrast, FIG. 14 shows an embodiment in which the sole plate 5 has an adjusting wedge 43 in its front end section, by means of which the inclination of the shoe cover in this area can be adjusted both in the longitudinal direction and transversely to the shoe. With the help of the longitudinal adjustment of such an adjustment wedge, a direct power transmission to the sole plate can be set for each shoe size. The adjustability of the lateral inclination of this adjustment wedge also enables the roller skate to be adapted to anatomical conditions, e.g. with X or bow legs. Such an adjustment can also be provided on the side support 7 in an embodiment not shown here. Furthermore, a cap or an adjusting wedge of this type can also be arranged in the heel area in order to be able to make appropriate adjustments and adjustments. It is also possible that an adjusting wedge arranged in the toe and / or in the heel area is designed to be elastic or is arranged on the sole support plate via an elastic intermediate layer, so that additional damping of vertical impacts is possible at these points.

From an orthopedic point of view, when using a roller skate of the type according to the invention, it is particularly important that the points of attachment of the fastening means or support means on the soleplate relate to the foot and are therefore fixed in an exact relationship to one another in order to transmit the force from the foot in a gentle and as direct manner as possible to ensure the skater on the shoe on the sole plate 5.

In Figure 15, the sole support plate 5 of an embodiment according to Figure 1 is shown in a schematic plan view, the points of attack A, E and F of the lateral Support 7 on the sole plate 5, the articulation point H of the cuff 8 and the points of attack C, D and G of the instep support 11 are shown in their orthopedically most favorable position. Points A and B lie in the longitudinal median plane ε and define the rear or front end of the sole plate 5, point A being arranged at the heel center of the heel at the rear end with respect to the skater's foot. At point C, which lies on the inside (side) of the sole plate 5 in the area of the base phalanx of the big toe, the fixation of the front section 12 of the tension band 11 is fixed, whereas the fixation of the rear section 13 of this band 11 lies in point D. , which is arranged in the area of the heel bone. The traction means 14 of the band 11 is guided at point G over the lateral support 7, the resulting tensile force starting from points C and D running over the instep in the direction of point A. On the outside of the shoe (laterally) there are two further points E and F on the edge of the sole plate, which define the rear and front ends of the front arm 7a of the side support 7. In relation to the foot, these two points are located on the metatarsal base and in the area of the base joint between toe V and ball. The rear arm 7b of the side support 7 is anchored to the sole plate 5 substantially symmetrically to the point A. Point H in turn defines the articulation of the cuff 8 on the lateral support 7 and is anatomically assigned to the lower leg in the area of the fibula.

With a consequent implementation of the orthopedic principles specified above, the following dimensions result for the position of the points C, D, E, F, G and H, which are given in relation to the distance AB using the table below, each with a range of possible dimensions and a preferred dimension lying in this range is indicated:

The points A to F all lie essentially in one plane, which is predetermined by the upper side of the sole support plate 5, whereas the points G and H are arranged at a distance above this sole support plate 5. For an orthopedically correct design of the system, not only the longitudinal and side dimensions of points A to H but also the height dimensions of points G and H are essential. If necessary, point B can also be arranged at a distance from the above-mentioned plane (see exemplary embodiment according to FIG. 14). The ranges specified for these points or the preferred values are shown in the following table, the dimensions also being given in relation to the distance AB:

For the practical design of a roller skate of the type according to the invention, three different sizes, e.g. Small, Medium and Large, provided, whereby the smaller sizes, starting from the largest model, are made 20% smaller in length and 10-15% higher in height. For the height of point H above the sole support plate 5 and the distance AB, measured in cm, this means, for example:

The mode of operation of a roller skate 1 according to the invention is briefly discussed below. The roller skate 1 is designed so that it can be used with any footwear and possibly barefoot within a size range. If such a roller skate 1 is now used together with a smaller or larger, in particular, however, a narrower or wider shoe, then an adjustment of the running direction or the position of the frame 2 for the rollers 3a, 3b, 3c, 3d with respect to the Sole plate 5 are made. This is done simply by loosening the lock (end nut 26, locking mechanism 27, 28, eccentric 36) of the guide device 16 and aligning the frame 2 in the desired direction by pivoting it with respect to the sole support plate 5 about the axis A. After the direction of travel has been set, the lock is tightened or tightened again and the roller skate 1 is ready for operation. The pivoting of the frame can of course also be used to correct misalignments of a foot. If this simple adjustment mechanism is not sufficient, a lateral adjustment of the axis A or a lateral adjustment of the lower leg support 6 can also be provided. However, the lower leg support 6 can also be adjusted as an alternative to pivoting the frame 2. In an embodiment variant not shown here, additional means can be provided via which the frame 2 can be adjusted with respect to the sole support plate 5 in the longitudinal direction of the frame in order to achieve an optimal longitudinal alignment of the rollers with respect to the center of gravity of the whole of the driver and roller skate.

Further exemplary embodiments of a roller skate according to the invention are shown below with reference to FIGS. 16 to 22. Features which correspond to those of the embodiments described above are provided with reference numerals increased by 100 each.

For the time being, reference is made to FIGS. 16 to 18, in which a further exemplary embodiment of a single-track roller skate 101 according to the invention is shown in two side views and one view from the rear. This roller skate 101 has a frame 102, in which four rollers 103 a, 103 b, 103c, 103d are arranged one behind the other in the longitudinal direction, each rotatable about a transverse axis. In the illustrated embodiment, a brake stub 104 is also provided at the rear end of the frame 102. The frame 102 is bonded to a sole support plate 105 with the aid of fastening and guide means, not shown here, the surface of which is essentially flat and is optionally provided with a friction-increasing support. At its front end, the sole support plate 105 is adapted to the natural shape of a shoe and is therefore slightly curved upwards.

In the present exemplary embodiment, a lower leg support 106 is provided on the outside of the shoe, which has a lateral support 107 projecting upward from the sole support plate, which is connected in the upper end section to a bracket 142 which is guided essentially behind half the lower leg and on its end located on the inside of the shoe is provided with a support 143 which is guided behind the ankle in the heel region, where it is supported on the sole support plate 105.

In the transition region between the bracket 142 and the lateral support 107 or the support 43, a closable sleeve 108 is rotatably mounted about a transverse axis B. The cuff 108 is padded on its inside facing the lower leg and is fastened by means of a suitable closure, e.g. by means of a toothed belt fastener 109, placed on the lower leg of the roller skater.

The support 107 is fork-shaped in the area below the ankle and has two arms 107a, 107b which, viewed from the side, are arranged essentially in the form of an upside-down Y. The forward arm 107a is connected to the middle of the shoe and the rearward arm 107b is connected to the sole support plate 105 in the heel region. The rear arm 107b is connected to the support 143 immediately above the sole support plate 105 in the region of the longitudinal median plane of the roller skate and thus forms a heel stop for the roller skater's shoe.

The lateral support 107 and the support 143 can each have an elastic section, by means of which a limited mobility of the cuff is made possible both in the longitudinal direction and in the direction transverse to the roller skate 101. Likewise, the bracket is of limited elasticity in the direction transverse to the longitudinal axis of the roller skate 101.

In the heel area of the roller skate 101, a support 110 is further provided to the rear, which is fastened to the support 107 and the support 43 in the exemplary embodiment shown. In the instep area of the roller skate 101, an instep support in the form of a tensionable band 111 is provided, which has a front section 112 and a rear section 113 in the area of the roller skate inside, the front section 112 in the ball area with the sole support plate 105 and the rear section 113 in the ankle area is connected to the sole support plate 105 and the rear section 112 of the band 111 which is guided rearward over the instep and the rear section 113 of the belt 111 which is guided forward over the instep and are connected to a traction means 114 which is connected to the front arm 107a on the roller skate outside the lateral support 107 is connected. The traction means 114 has a suitable tensioning device 115, by means of which the band 111 can be tensioned, loosened or fixed. The traction means 114 and the tensioning device 115 can also be a toothed belt lock, for example.

In the heel section of the roller skate, the frame 102 is articulated on this sole support plate 105 about an axis A oriented essentially normal to the sole support plate 105. Such articulation can be done by any known means, e.g. a rotatably mounted pin. The axis A is preferably arranged in the longitudinal center plane of the roller skate.

In the ball section of the roller skate, on the other hand, a lockable guide device 116 is provided for the frame 102, by means of which the frame 102 can be pivoted to a limited extent about the axis A with respect to the sole support plate 105.

From an orthopedic point of view, when using a roller skate of the type according to the invention, it is particularly important that the points of attack of the fastening or support means are matched to the anatomical conditions of the foot and are therefore fixed in an exact relationship to one another in order to transmit the force from the foot in a gentle and as direct manner as possible to ensure the skater on the shoe on the sole plate 105.

The mode of operation of a roller skate 101 according to the invention is briefly discussed below. The roller skate 101 is designed so that it can be used within a size range with any footwear and possibly barefoot. If such a roller skate 101 is now used together with a smaller or larger, but in particular a narrower or wider, shoe, it is advantageously possible to adjust the running direction or the position of the frame 102 for the rollers 103 a, 103 b, 103c, 103d be made with respect to the sole support plate 105. The cuff 108 is held particularly stable in a roller skate of this type by the bilateral mounting, so that a correspondingly firm hold of the lower leg is ensured even under extremely heavy loads, such as occur, for example, when jumping. The lateral support 107, with its arms 107a and 107b, additionally forms a lateral and rear stop for the skater's shoe, whereas the support 143 is guided behind the ankle in the heel area and therefore leaves sufficient scope for shoes of different widths. The bracket 142 is sufficiently side-elastic so that the cuff 108 can be easily adapted to lower legs of different widths. Also, getting in and out of roller skate 101 is advantageously not hindered by additional support 143. Furthermore, there is the possibility of producing such a roller skate with few parts, since the sole support plate 105, the lateral support 107, the bracket 142 and the support 143 can be produced in one piece, for example from a fiber-reinforced plastic.

At this point it should also be noted that the present invention is not restricted to the exemplary embodiment shown in FIGS. 16 to 18. For example, roller skates of the type according to the invention can have a support 143 for the bracket 142 other than the one shown here. Furthermore, any cuffs and instep supports can be used within the scope of the present invention. For example, the cuff cannot be sewn, as shown, but can be foamed. As a result, the manufacturing costs can be reduced further in an advantageous manner. In such an embodiment with a foamed cuff, an extension projecting downward from the cuff can also be provided for cushioning the inside of the upwardly extending support 107, this extension being foamed in one piece with the cuff. Furthermore, instep supports other than those shown can be provided. In particular, in an embodiment not shown here, limited elastic zones can be provided in the instep supports, which allow a better adaptation of the instep support to the surface of the shoe used by the roller skater and therefore enable a better hold of this shoe on the sole support plate. This can be achieved, for example, on the one hand by the sections of the band 112, 113 being designed to be elastic, or on the other hand by the connection area of the bands 112, 113, to which the traction means 114 engages, being of limited elasticity. A limited elastic area of the instep support can be produced, inter alia, by providing a lattice-shaped structure at least in sections, in which certain sections (webs) have a certain elasticity. The elasticity of such webs can be significantly increased if they are zigzag or snake-shaped. A structure of this type can be easily molded from a plastic. FIG. 19 shows a further exemplary embodiment of a roller skate 201 according to the invention, in which the lower leg support has a support 207 which projects upwards in the heel region, at the upper end of which a U-shaped bracket 242 which surrounds the cuff 208 around the rear is arranged approximately halfway. As in the exemplary embodiment in FIGS. 16 to 18, the cuff 208 is mounted on this bracket so as to be pivotable about a transverse axis.

In this exemplary embodiment, the support 207 has a higher elasticity in the longitudinal direction of the shoe than that of the previous exemplary embodiments, so that this roller skate can be driven extremely comfortably and is particularly suitable for long-distance journeys. Likewise, due to the design-related elasticity, a special mounting of the cuff, as is shown, for example, in FIGS. 8 to 10, can be dispensed with, so that inexpensive manufacture of the roller skate is possible. The support 207, on the other hand, has a certain width, depending on the material, which has the result that the sleeve is held sufficiently stable against lateral movement and rotation. Fiber-reinforced plastic is particularly suitable as the material for the support 207 and the sole support plate 205.

The frame 202 for the rollers 203a, 203b, 203c, 203d and the sole support plate 205, as well as the pivotability of these parts relative to one another, are realized in this exemplary embodiment essentially the same as in the exemplary embodiment according to FIG. 1 or that of FIGS. 16 to 18, so that in FIG the following is no longer discussed in more detail.

The instep support also has, in the exemplary embodiment according to FIG. 19, a front and rear band 212, 213 fastened on the inside of the shoe to the sole support plate 205 and which are guided over the instep in the direction of the outside of the shoe. The rear band 213 is connected to the traction means 214, which is fastened to the sole plate 205 on the outside of the shoe in the heel region. The traction means 214 is tensioned by means of a suitable tensioning device 215, in the present case this is a toothed belt lock. In this exemplary embodiment, however, the front band 212 is not connected to the traction means 214, but rather is fastened in the toe area directly to the outside of the shoe and has a separate tensioning and traction means, for example a Velcro fastener. Below the belts 212, 213 and the traction means 214, a flat support 244 of the instep support is provided in the instep area, which uniformly distributes the pressure generated by tensioning the traction means on the upper side of the shoe. This embodiment advantageously brings about a stronger hold of the skater's shoe on the sole support plate 205 in the toe area of the roller skate. Another embodiment of a roller skate 301 according to the invention is shown in FIGS. 20 and 21. In this embodiment, both the side support 307 and the sole support plate 305 and the frame 302 for the rollers 303a, 303b, 303c, 303d are made of a light metal, for example aluminum. A particularly stable variant of the roller skate according to the invention can thereby be created. In order to save weight, openings 245a, 245b, 345c are cut out in the support 307, in the frame 302 and optionally in the sole plate 305 at various points. In this embodiment, it is further provided that the support 207 is releasably attached to the sole support plate 305, so that this support 307 can be removed from the sole support plate 305 when the roller skate is not in use and the roller skate 301 can be transported and stored in this state with a particularly small space requirement , for example when traveling. The exact design of the detachable connection is not shown in detail here since there are a large number of different options. All means known to the person skilled in the art can therefore be used for the releasable fastening of the support 307 to the sole support plate 305, but quick-release fasteners, such as, for example, latching plug connections, are particularly suitable. But it is also conceivable that the releasable connection is a simple screw connection, since the roller skater is supplied with a suitable tool for changing the rollers anyway when purchasing the roller skate. A solution of the type with a releasable support can of course also be provided in all other embodiments of roller skates 1, 101, 201 according to the invention described above. As in the exemplary embodiment in FIGS. 16 to 18, a U-shaped bracket 342 is also provided in the exemplary embodiment in accordance with FIGS. 20 and 21 to improve the stability at the upper end of the support 307, and is guided around the collar 308 and the latter essentially encloses in half.

The instep support is also formed in this embodiment by a front and a rear band 312, 313, which are brought together to form a single band 311, on which the traction means 314 acts, which is designed here as a Velcro fastener. FIG. 21 also shows that the support arranged in the heel area is connected to the rear 310 by means of a tensionable band 346 with the rear band 313 of the instep support. This fixable support 310 also ensures a particularly firm hold of the shoe used by the roller skater on the sole plate 305 or the support 307 in the heel area. In the exemplary embodiment shown, a Velcro fastener arranged on the band 346 is provided for tensioning the foot support 310. Of course, all other suitable means can also be used for this.

The cuff 308 is shown as a sewn cuff, which here can be fixed to the lower leg by means of a Velcro fastener 309. FIGS. 22 and 23 show a further exemplary embodiment of a roller skate 401 according to the invention, in which the roller frame, the rollers and the instep support are only shown schematically in their outlines. In contrast to the previous exemplary embodiments, no lower leg support of the conventional type is provided in the case of the one shown in FIGS. 22 and 23, but only a lateral stop 407a and a rear stop 407b for the shoe of the roller skater. The stop 407a arranged above the sole plate 405 on the outside thereof is formed by a short support projecting upwards and backwards, which in the ankle area forms a single, arch-shaped support 407 with a support which extends from the heel area and forms the rear stop 407b is connected, which extends from the sole plate 405 upward just above the ankle area. This embodiment is particularly suitable as a training device for athletic runners, for example speed skaters.

Finally, it should also be mentioned that in the context of the present invention, the individual features of different exemplary embodiments can be combined with one another as desired or interchangeable with one another in order to obtain further design variants of a roller skate according to the invention. There is also the possibility that the parts of such a roller skate are purchased individually or in a set and are assembled by the roller skater himself into a roller skate of the type according to the invention. This variant is also included in the protective cover of the present invention.
