[0001] REPLACEABLE INLINE SLIDES
[0002] Technical area
[0003] The present invention relates to the field of a replaceable inline glider for attachment to a bracket on an ice skate for use on synthetic ice.
[0004] State of the art
[0005] A variety of so-called inline skates are known in the art. These were developed as a replacement for ice skates for training during the warmer months on hard surfaces such as asphalt, wood, or natural stone. Such inline skates typically feature a frame designed to accommodate two to six hard rubber wheels. The hard rubber wheels contain a centered bearing and are arranged one behind the other on fixed axles.
[0006] However, in recent decades the popularity of synthetic ice, which consists of polyethylene sheets, has increased significantly, and training takes place more and more on synthetic ice surfaces during the warmer months. Conventional ice skate blades, however, are unsuitable for use on synthetic ice. On the one hand, conventional ice skate blades have a significantly higher coefficient of sliding friction on synthetic ice than on natural ice. On the other hand, skating and braking movements cause damage such as notches and abrasion in the form of polyethylene chips on the synthetic ice surface, which further severely impair the gliding ability of conventional ice skate blades. As a result, when using ice skate blades on synthetic ice, significantly more effort is required to move forward than on natural ice.To accommodate this, various inline skates have been developed for use on synthetic ice surfaces. For example, EP1008372A1 and WO9745180 disclose four to five centrally mounted steel wheels, ground on the contact surface, which are compatible with and can be attached to conventional inline skates, thus making them interchangeable with hard rubber wheels. This eliminates the need to redesign the skates, as converting from hard rubber wheels to steel wheels and vice versa is easily possible.
[0007] Furthermore, DE8402692U 1 discloses, for example, a plurality of ball bearings arranged one behind the other, the outer rings of which form the rollers and the inner rings of which are clamped between two wall parts, wherein the wall parts are convergently bevelled in the area of the roller axes in order to enable curved running.
[0008] Description of the invention
[0009] However, one disadvantage of all these state-of-the-art inline skates is that their driving / gliding behavior on synthetic ice is unsatisfactory and cannot create a realistic ice skating experience.
[0010] Another disadvantage of conventional inline skates with steel wheels is their low rolling bearing stability. The forces acting on the rolling bearings during gliding often result in a significant loss of rolling ability, which is frequently caused by fatigue and insufficient bearing stability.
[0011] An additional disadvantage of conventional inline skates with steel wheels is that the steel wheels are not compatible with the skate used on natural ice and are therefore not interchangeable with the skate blade. As a result, they are often only usable in conjunction with conventional inline skate shoes or are not interchangeable at all.
[0012] It is therefore the general object of the invention to further develop the state of the art in the field of inline skates and, preferably, to overcome one or more disadvantages of the prior art. In advantageous embodiments, a replaceable gliding element is provided which, on synthetic ice, exhibits an almost realistic gliding behavior with the same effort as a skate blade on natural ice.
[0013] The general object of the invention is achieved by the subject matter of the independent patent claim. Further advantageous embodiments emerge from the dependent patent claims and the disclosure as a whole.
[0014] The sliding body according to the invention for ice sports equipment, in particular for ice skates, comprises two wall elements, which comprise a roller fastening section and a mounting web fastening section, wherein the roller fastening section comprises a front, a middle, and a rear section and bearings inserted into the wall elements. Furthermore, the sliding body comprises a plurality of rollers arranged one behind the other. The rollers each comprise an axle and are arranged between the first and second wall elements along the roller fastening section, wherein the axles are inserted into the bearings of the wall elements. An arrangement of the bearings in the wall elements allows for a rotating axle, internal bearing rotation, and an integrally formed axle rigidly arranged on the respective roller, which on the one hand increases the stability of the sliding body and on the other hand improves the sliding behavior.Furthermore, the wheels comprise a rolling surface, with the rolling surfaces comprising a grinding surface. The term "gliding body" used in this disclosure refers to a replacement for blades for use on synthetic ice, wherein the gliding motion is imitated by the arrangement of the wheels.
[0015] Directional information as used in the present disclosure is used in relation to the attached sliding body on an ice sports device, in particular on an ice skate, in use. The directional information is therefore to be understood as follows: The longitudinal direction of the sliding body is described by an axis from the forefoot area to the heel area and thus extends along the longitudinal axis of the sliding body. The transverse direction of the sliding body runs transversely to the longitudinal axis and thus along a transverse axis and defines the thickness of the sliding body. The vertical direction in the context of the present invention refers to a direction from the rolling surface of the sliding body towards the ice skate, or in the operative state towards the shoe, and thus runs along a vertical axis of the sliding body.
[0016] The sliding body has a length that extends along the longitudinal axis between two opposite ends, wherein the sliding body length depends on the type of ice sport and the length of the boot to which the sliding body is attached. The sliding body length is preferably equal to or greater than the length of the wall elements and extends for ice hockey, bandy, and figure skating in a range of 1.50 mm to 350 mm, preferably between 1.60 mm and 330 mm, and for speed skating in a range of 1.50 mm to 550 mm, preferably between 1.60 mm and 500 mm.
[0017] The sliding body also has a sliding body height and a sliding body thickness. The sliding body height extends vertically along the vertical axis, i.e. in use from the rolling surface to the mounting bar support elements, which are described in detail below. The sliding body height is in a range between 20 mm and 100 mm, for ice hockey and bandy sports preferably in a range between 25 mm and 50 mm and for figure skating and speed skating preferably between 40 mm and 75 mm. The sliding body thickness extends along the transverse axis and extends from the outside of the first wall element to the outside of the second wall element and thus includes the two wall elements as well as the rollers arranged therebetween. The sliding body thickness is in a range between 6 mm and 15 mm, preferably in a range of 8 mm to 12 mm.
[0018] In further embodiments, the sliding body can have a planar outer structure in the vertical direction. This means that the outer surface of the wall elements and the bearings and fastening means attached to the wall elements can be present as a planar surface in the vertical direction.
[0019] The two wall elements have a wall element length, with the wall element length lying in a range of between 150 mm and 550 mm. The wall element length extends in the vertical direction and depends on the number of rollers, the diameter of the rollers, the distance between the rollers arranged one behind the other and the type of ice sport. Typically, the wall element length is the same length as the sliding body length. It goes without saying that the sliding element length can also be marginally longer than the wall element length. This can be the case, for example, if the two outermost rollers in the longitudinal direction are attached between the two wall elements in such a way that they protrude in the axial direction between the two wall elements, with the two outermost points of the rollers in the longitudinal direction then defining the sliding body length. Furthermore, the wall elements have a wall element height and a wall element thickness.The wall element height is in a range between 1.5 mm and 30 mm, preferably between 1.8 mm and 25 mm, and extends in the vertical direction. It is understood that the wall element height can vary along the longitudinal direction. The wall element thickness is in a range between 1 mm and 5 mm, preferably between 1.5 mm and 3 mm and extends along the transverse direction. Furthermore, the two wall elements are preferably each formed in one piece and can consist of metal or metal alloys or of carbon-reinforced plastic fibers. If the wall elements consist of several metals, these materials are preferably constructed in a sandwich design. The cover layers can consist of a metal alloy such as steel, for example, and the core can consist of aluminum, for example.The wall elements each have an outer and an inner side, a lower end in the roller attachment section, and an upper end in the mounting bar attachment section, wherein the roller attachment section lies along the vertical axis in the direction of the sliding surface and the mounting attachment section lies in the direction of the skate. The roller attachment section further has a front, middle, and rear section. In some embodiments, the wall elements in the front and / or rear sections can have a curvature in the vertical direction, i.e., in the direction of the skate, and thus, for example, replicate the shape of an ice hockey blade. Furthermore, the curvatures in the front and / or rear sections can have the same or different curvature curves.
[0020] Preferably, the two opposing wall elements extend vertically parallel along the vertical axis. This means that the two opposing wall elements have a gap that is constant in size along the vertical axis between the lower and upper ends. Alternatively, the first and / or second wall element can extend vertically at an angle to the vertical axis, wherein the angle can be between 0.5° and 5°, preferably between 1° and 3°, inclined inwards or inclined outwards to the vertical axis, which can lead to a decrease or an increase in the size of the gap between the two wall elements.
[0021] In preferred embodiments, the wall elements can be
[0022] contain recesses. These recesses are preferably located on the roller fastening section between the bearings inserted into the wall elements, which are described in detail below. Alternatively, the recesses can also be made on the mounting web fastening section. Preferably, all recesses have the same shape and dimensions, whereby the recesses can be in the form of an arc of a circle, a semi-oval, a polygonal shape or any concave shape. Alternatively, however, the individual recesses can also have different shapes and dimensions. If the recesses are located in the roller fastening section, the dimension of the recesses is preferably selected such that their height in the vertical direction, i.e. in the direction of the shoe, does not exceed the center point of the bearings inserted into the wall elements.If, however, the recesses are provided in the mounting fastening section, the dimension of the recesses is preferably selected such that the height of the recesses in the vertical direction, ie in the direction of the rolling surface, does not exceed the center of the holes provided in the wall elements, which are described in detail below.
[0023] Furthermore, the wall elements contain openings or blind holes in the roller fastening section into which the bearings are inserted, whereby the number of openings or blind holes in each wall element corresponds to the number of rollers. The openings / blind holes can be made in the vertical direction with a distance of between 4 mm and 1 5 mm from the lower end, whereby the vertical distance depends on the diameter of the rollers. The distance between the openings / blind holes in the longitudinal direction depends on the number of rollers, the diameter of the rollers and the distance between the individual rollers and is between 18 mm and 45 mm. The diameter of the openings / blind holes is between 6 mm and 10 mm and is designed so that the respective bearings can be inserted into the openings / blind holes by means of a press fit.For additional adhesion, the bearings press-fitted into the openings / blind holes can be secured with a suitable instant adhesive. The bearings inserted into the openings / blind holes can be plain or roller bearings, with roller bearings, in particular ball bearings, being preferred. The outer diameter of the ball bearings used can be between 6 mm and 10 mm, preferably between 8 mm and 9.5 mm, the diameter of the bearing bore between 3 mm and 7 mm, preferably between 4.5 mm and 5.5 mm, and the nominal width between 1.5 mm and 7.5 mm, preferably between 2 mm and 7 mm, particularly preferably 4 mm. Furthermore, in embodiments in which the wall elements have openings, closed bearings can be used on the outside of the wall element.
[0024] In order to connect the individual wall elements and the intermediate mounting web, which is described in detail below, with suitable fastening means, the wall elements have holes in the mounting web fastening section area. Preferably, each wall element has holes with conical recesses for attaching, for example, countersunk screws, while the holes in the second wall element each have a thread. In a more cost-effective embodiment, rivets are used instead of screw connections, preferably with chrome steel screws.
[0025] The rollers arranged between the two wall elements with a roller spacing of 0.5 mm and 3.5 mm, preferably between 1 mm and 3 mm, have the shape of a disk with a diameter between 1.5 mm and 40 mm, preferably between 20 mm and 30 mm and a thickness between 0.5 mm and 4 mm, for ice hockey, bandy and figure skating preferably between 2.5 mm and 4 mm and for speed skating preferably between 0.9 mm and 2 mm. The rollers are each arranged centrally on an axle with an axle diameter between 3.0 mm and 7.0 mm and an axle length between 5.0 mm and 1.3 mm, wherein the axle and the roller can either be formed as one piece or the axle can be fastened in the respective roller by means of a press fit. Furthermore, in preferred embodiments, a form-locking means, preferably in the form of a depression, can be arranged on the axles at the end in the transverse direction.The positive locking device can be connected to the corresponding positive locking device, thus creating a positive connection. It serves to ensure the rotation of the rollers during grinding of the rolling surfaces. Furthermore, spacer discs with a maximum outer diameter of 10 mm and a maximum thickness of 0.6 mm are preferably attached to both sides of the rollers. The spacer discs can be formed integrally with the respective roller and the associated axle, or the spacer discs can be press-fitted to both sides of the rollers and the respective axle. The inner diameter of the spacer discs is then selected so that the spacer disc can be press-fitted to the axle.
[0026] The rollers, or rather the axles, are inserted into the bearings of the two opposite wall elements. The number of rollers arranged one behind the other depends on the wall element length, the roller diameter, the distance between the individual rollers and the type of ice sport. The rollers are arranged between the two wall elements in such a way that the contact points of the rolling surfaces in the middle section preferably lie on a curve, with the radius of the curve being able to range from 1,500 mm to infinity. Furthermore, the rollers in the front section and the rear section are arranged between the two wall elements in such a way that the contact points of the rolling surfaces in the front section and / or the rear section each lie on a curve, with the radii of the curves being able to range from 100 mm to infinity.
[0027] Furthermore, the rollers have a rolling surface that comes into contact with a sliding surface, such as a synthetic ice surface, wherein the rolling surfaces each have a ground surface, preferably a hollow ground or a flat ground surface. The ground surface is applied to the rolling surface of the rollers in such a way that at least one ground edge of the ground rolling surface is aligned with a side surface of the roller. It is understood that the hollow ground corresponds to a hollow ground of an ice skate blade, known to those skilled in the art, and thus comprises a concave surface with a radius and two outer ground edges. The flat ground corresponds to a flat ground of a speed skate blade, known to those skilled in the art, and can comprise an angle with respect to the sliding plane. Such a hollow or flat ground surface is applied to reduce the frictional resistance to the sliding surface and thereby generate higher speeds.The hollow grind and the flat grind can be the same for all wheels or, alternatively, can be designed differently depending on the wheel position on the gliding body in order to achieve optimal gliding behavior on synthetic ice.
[0028] In preferred embodiments, the individual rollers can contain a plurality of recesses to reduce weight. The recesses can also be designed as openings. The recesses are preferably arranged symmetrically around the axis. The recesses can be circular or elliptical, or alternatively polygonal. The recesses are located on the side surfaces of the rollers and preferably take up no more than 50% of the total area of the side surface. For a roller diameter of 20-30 mm, 8 cylindrical openings with a diameter of 3 to a maximum of 5 mm have proven advantageous, whereby here too, no more than 50% of the total side surface of the roller is taken up by the openings. According to an advantageous embodiment, the diameter of the 8 openings is 4 mm for a roller diameter of 25 mm.
[0029] In further embodiments, the rollers in a sliding body are arranged between the first and second wall elements along the roller attachment section such that the contact points of the rolling surfaces of three to seven rollers in the middle section lie on a straight line. This means that the rollers in the middle section are arranged one behind the other such that the contact points of the rolling surfaces that come into contact with the sliding surface, in particular the synthetic ice surface, lie on a straight line. If not all of the rollers arranged in the middle section lie on a straight line, then preferably the rollers that form the middle rollers in the middle section lie on a straight line. The number of rollers lying on a straight line is defined, for example in ice hockey, by the driving behavior and the player's position. The smaller the contact surface, this meansThe fewer wheels in the middle section are in a straight line, the more maneuverable and easy to turn the glider is, which may be desirable for a striker position, for example. The more wheels in the middle section are in a straight line, the larger the contact surface and the more stable the stance on the glider is, which may be desirable for a defensive position, for example.
[0030] In further embodiments, the rollers in a sliding body are arranged between the first and second wall elements along the roller attachment section such that the contact points of the rolling surfaces in the front and / or rear section lie on a front and / or rear curvature line. The front and rear curvature lines can have either the same or a different radius of curvature, whereby the radius of curvature can be between 100 mm and 1000 mm or, for speed skating, between 23 m and 27 m. The smaller the radius of curvature, the sharper the curvature. In other words, the smaller the radius of curvature, the sharper the curvature in the vertical direction, i.e., bent towards the boot during use. In ice hockey, for example, the curvature allows the sliding body to rotate in a different direction on synthetic ice.In speed skating, for example, a very slight curvature in the front and / or rear section can help to enable better cornering.
[0031] In further embodiments, the rollers in a sliding body are arranged between the first and second wall elements along the roller attachment section such that the contact points of the rolling surfaces of all rollers lie on a straight line. Such an embodiment is preferably used in speed skating. In further embodiments, the rollers in a sliding body are arranged between the first and second wall elements along the roller attachment section such that the rollers have a roller projection of between 20% and 40%, preferably between 25% and 35%. The roller projection refers to the portion of the roller diameter of the respective roller which, in the direction of the sliding plane, is not accommodated in the space formed by the two opposing wall elements.It is understood that due to the rotating movement of the rollers, the portion of the roller diameter that forms the roller projection is always that portion which at this point in time is not in the space formed by the two wall elements.
[0032] In further embodiments, the rollers in a sliding body are arranged between the first and second wall elements along the roller fastening section such that the individual rollers have the same roller projection. In a preferred embodiment, the roller projection of the sliding body is between 25% and 35%, wherein the sliding body has 10 to 14 rollers arranged one behind the other with a roller thickness of 2.5 mm to 4 mm and a roller diameter of 20 mm to 30 mm. In a further preferred embodiment, the roller projection of the sliding body is between 25% and 35%, wherein the sliding body has 15 to 19 rollers arranged one behind the other with a roller thickness of 0.9 mm to 2 mm and a roller diameter of 20 mm to 30 mm. In a further embodiment, the roller projection of the sliding body is between 25% and 35%, wherein the sliding body has 8 to 12 rollers arranged one behind the other with a roller thickness of 2.5 mm to 4 mm and a roller diameter of 20 mm to 30 mm.5 mm to 4 mm and a roller diameter of 20 mm to 30 mm and in the front section of the roller fastening section a non-movable toothed element, which is described in detail below, with a thickness of 2.5 mm to 4 mm.
[0033] In further embodiments, the rollers in a sliding body are arranged between the first and second wall elements along the roller attachment section such that at least one roller has a different projection than the other rollers. If there are multiple rollers with different projections, these projections can also differ from one another.
[0034] In further embodiments, the rollers in a sliding body each have the same diameter. In a preferred embodiment, the roller diameter is between 20 mm and 30 mm with a roller thickness between 2.5 mm and 4 mm. In another preferred embodiment, the roller diameter is between 20 mm and 30 mm with a roller thickness between 0.9 mm and 2 mm.
[0035] In further embodiments, the rollers in a sliding body each have the same roller thickness, wherein the roller thickness for speed skating is preferably between 0.9 mm and 2 mm and for ice hockey, bandy and figure skating is preferably between 2.5 mm and 4 mm.
[0036] In further embodiments, the rollers are each arranged one behind the other at the same distance. In a preferred embodiment, the distance between the rollers arranged one behind the other is between 1 mm and 3 mm, wherein the sliding body in this embodiment has 10 to 14 rollers arranged one behind the other with a roller diameter of 20 mm and 30 mm and a roller thickness of 2.5 mm and 4 mm. In a further preferred embodiment, the distance between the rollers arranged one behind the other is between 1 mm and 3 mm, wherein the sliding body in this embodiment has 15 to 19 rollers arranged one behind the other with a roller thickness of 0.9 mm to 2 mm and a roller diameter of 20 mm to 30 mm.
[0037] In further embodiments, the number of rollers is between 7 and 22. The number of rollers depends on the length of the wall elements, the roller diameter and the distance between the rollers arranged one behind the other. Furthermore, the number of rollers differs depending on the sport and is between 10 and 17, preferably between 10 and 14, for ice hockey and bandy, between 15 and 22, preferably between 15 and 19, and for figure skating between 7 and 14, preferably between 7 and 12. For figure skating, the two outermost rollers in the front section of the roller attachment section can be replaced by a non-movable spiked element, the thickness of the spiked element in the transverse direction corresponding to the roller thickness selected in this embodiment.
[0038] In further embodiments, the grinding of the rolling surface has a hollow grind with a hollow grind radius between 9 mm and 26 mm or a flat grind with an angle to the sliding surface between 0° and 40°. In preferred embodiments, the hollow grind radii are between 9 mm and 10 mm or between 1.2 mm and 1.3 mm or between 1.5 mm and 1.6 mm or between 25 mm and 26 mm, and correspond to the hollow grind radii of an ice skate blade for use in ice sports, such as ice hockey. Furthermore, the angle of the flat grind is preferably between 0° and 30° and corresponds to a flat grind of an ice skate blade for use in speed skating.
[0039] In further embodiments, the rollers are made of a metal alloy, hard plastic, or ceramic. The metal alloy is preferably made of stainless steel with a Rockwell hardness between 50 and 65, preferably between 54 and 62; more preferably between 54 and 58, preferably vacuum-hardened. To increase the durability of the rollers, the rollers can be provided with an additional coating, such as a hardness-determining titanium coating and / or a grinding sharpness-determining coating and / or a QPQ coating.
[0040] In further embodiments, the individual rollers in a sliding body are interchangeable.
[0041] This means that the wall elements, the rollers with their associated axles, and the mounting bridge, which is described in detail below, are connected to each other in the sliding body in such a way that at least one wall element is designed so that its connection can be removed and the rollers replaced. It goes without saying that the rollers are replaced along with the axles, since the axles and rollers are formed as a single piece, or the axles are attached to the roller by means of a press fit.
[0042] In further embodiments, a mounting web is arranged between the first and second wall elements. The mounting web has an upper and a lower end and is typically formed in one piece. The mounting web can be made, for example, from carbon-reinforced plastic fibers, from metals, or from metal alloys. If the mounting web is made of a metal alloy, this metal alloy is preferably an aluminum alloy. If the mounting web is made of more than one metal alloy, the mounting web preferably has a sandwich construction due to the arrangement of the alloys. The sandwich construction can, for example, consist of a steel-aluminum-steel sandwich construction. The outer steel layers preferably have a thickness of 0.2 to 0.5 mm, with a total thickness of the steel-aluminum-steel sandwich of 2.8 - 2.9 mm.
[0043] The mounting web extends longitudinally and, in its length and curvature, preferably corresponds to the length and curvature of the wall elements and thus to the length of the sliding body. The thickness of the mounting web in the transverse direction can depend on the length of the axis and is preferably selected such that the wall elements have a constant gap along the vertical axis due to the arrangement of the axes inserted into the wall element bearings and the mounting web thickness.
[0044] Furthermore, the mounting bar contains mounting bar support elements, which are arranged in vertical
[0045] Direction at the upper end of the mounting bar, i.e. in the direction of the boot when in use. The mounting bar holder elements form the suitable counterpart for attachment to the holder of the respective ice sports equipment, in particular an ice skate, and can be detachably connected to a compatible holder element of the respective boot, whereby the mounting bar holder elements correspond to the well-known holder elements of ice skate blades, where the connection can be detached and connected without considerable effort. Depending on the sport and the position of the player, as well as the design of the complementary holder on the skate, the mounting bar holder elements are available in different designs and numbers. In addition, the mounting bar holder elements can be provided with recesses for additional weight reduction.
[0046] In further embodiments, additional spacers can be attached to both sides of the mounting bar.
[0047] In preferred embodiments, the mounting bar can contain mounting bar recesses in the vertical direction at the lower end, i.e., when used in the direction of the sliding plane, wherein the number of mounting bar recesses corresponds to the number of rollers in a sliding body. The mounting bar recesses can be in the shape of a circular arc and are sized such that the rollers with the respective diameter can be partially accommodated in the mounting bar recess at a distance from the mounting bar recess of 18 mm to 45 mm.
[0048] To connect the mounting bar to the wall elements, the mounting bar has mounting bar holes, whereby the diameter and the number of mounting holes in the mounting bar depend on the diameter and the number of holes in the wall elements. In addition, the positions of the
[0049] The mounting bar holes align with the positions of the holes in the wall elements so that the mounting bar can be correctly installed between the two wall elements. Furthermore, the mounting bar is positioned and connected between the two wall elements in such a way that the mounting bar support elements form a vertical projection, i.e., in the direction of the skate during use, so that the mounting bar support elements can be inserted into the corresponding counterpart of the respective ice sports equipment, in particular the ice skate, for attachment.
[0050] In further embodiments, the wall elements consist of at least one metal alloy. If the wall elements consist of only one metal alloy, they preferably consist of an aluminum alloy, such as an aluminum alloy from alloy group 7000.
[0051] In further embodiments, the wall elements have a sandwich construction due to the metal alloys. The respective cover layers preferably consist of a steel alloy, such as a steel alloy from material group 1.2343 or 1.2312 or 1.2112, and the core consists of an aluminum alloy, such as an aluminum alloy from alloy group 7000. According to a further advantageous embodiment, the outer steel layers of the steel-aluminum-steel sandwich have a thickness of 0.2 to 0.5 mm, with a total thickness of the sandwich construction of 2.0 to 2.5 mm. A preferred material for the steel layers is 1.4043.
[0052] In further embodiments, the wall elements are made of carbon fiber reinforced plastic. Recycled carbon material or Carbotylene with a
[0053] Thickness of 2 to 3 mm is used.

[0064] The schematic side view shown in Figure 1 shows an embodiment of a sliding body 1 for an ice skate or ice hockey boot. The sliding body 1 is shown in a side view and has a sliding body length 1 1 of 272 mm and a sliding body height 1 2 of 47 mm. The wall elements 1 4- 1 shown in this embodiment are formed in one piece and each comprise thirteen arranged bearings 143 in the roller fastening section 141, each bearing having an outer diameter of 9 mm and a bearing bore of 5 mm. In this embodiment, the bearings are closed on the outer side of the wall element. Furthermore, the sliding body 1 shown in Figure 1 has thirteen rollers 15 arranged one behind the other between the two wall elements 14-1 in the roller fastening section 141, wherein three rollers 15 are arranged in the front section 1411, seven rollers 15 are arranged in the middle section 1412 and three rollers 15 are arranged in the rear section 1413.In this embodiment, the rollers 15 all have the same roller diameter of 23 mm and a uniform roller projection 155, wherein the roller projection 155 for all rollers is 30% of the roller diameter. Furthermore, the wall elements 14-1 have twelve recesses 147 between the inserted bearings 143 in the roller fastening section 141, wherein the recesses 147 all have a concave contour in this embodiment. The sliding body 1 shown in this embodiment further comprises a mounting web 16 between the two wall elements 14-1 in the mounting web fastening section 142, wherein the mounting web 16 comprises three mounting web holding elements 161. The fastening means 17 used in this embodiment to fasten the two wall elements 14-1 and the mounting web 16 are countersunk screws.
