Description

The present invention relates to a sliding guide shoe with the features of the preamble of claim 1.

Sliding guide shoes for elevators are well known in the art.

For example, in the WO 2020/002409 A1 A sliding guide shoe is disclosed which is to be manufactured in the form of a composite component made of plastic.

Other known sliding shoes have a metal housing, both in simple designs in which a damping element is inserted into the guide recess and in complex designs in which the positions of damping elements or sliding elements are adjustable.

The object of the invention is to provide a sliding guide shoe which enables a wider field of application and/or simpler production compared to the prior art.

• ein Gehäuse mit einer Führungsausnehmung zum Aufnehmen von Schienenelementen der Aufzüge,
• einem in der Führungsausnehmung angeordneten Gleitelement zur gleitenden Führung der Schienenelemente sowie
• zumindest einem zwischen dem Gehäuse und dem Gleitelement angeordneten Dämpfungselement,

wobei das Gleitelement zum Anpassen des Gleitführungsschuhs an unterschiedliche Geometrien, insbesondere Dicken, der Schienenelemente zumindest zwei Gleitelementkomponenten aufweist, welche in unterschiedlichen Relativpositionen zueinander in der Führungsausnehmung angeordnet oder anordenbar sind, und dass die Relativposition der Gleitelementkomponenten durch das zumindest eine Dämpfungselement zumindest teilweise festgelegt ist.This object is achieved by the features of claim 1 in that

• a housing with a guide recess for receiving rail elements of the elevators,
• a sliding element arranged in the guide recess for the sliding guidance of the rail elements and
• at least one damping element arranged between the housing and the sliding element,

wherein the sliding element for adapting the sliding guide shoe to different geometries, in particular thicknesses, of the rail elements has at least two sliding element components which are arranged or can be arranged in different relative positions to one another in the guide recess, and that the relative position of the sliding element components is at least partially determined by the at least one damping element.

This means that with the sliding guide shoe according to the invention, a wide variety of geometries, in particular thicknesses, of the rail elements of the elevators can be reproduced by using the damping elements suitable for a desired geometry when assembling the sliding guide shoe.

In other words, the sliding guide shoe according to the invention can be adapted to the geometry of the existing rail elements by means of the damping elements used, without the need for a complex housing with adjustment options or a complex manufacturing process.

The sliding guide shoe according to the invention could therefore be called a modular sliding guide shoe.

If more than one damping element is provided, some or, preferably, all of the damping elements may be specifically adapted or suitable for the geometry of the rail element.

Protection is also sought for an elevator with at least one rail element and at least one sliding guide shoe according to the invention.

Protection is also sought for a set comprising a sliding guide shoe according to the invention and at least one further damping element, preferably several further damping elements or sets of damping elements, wherein the at least one damping element and the at least one further damping element are suitable for different geometries, in particular thicknesses, of rail elements.

If such a set is used, the assembly personnel do not even have to know exactly what type of guide is involved, because all common rail elements for elevators can be covered with the sliding guide shoe and/or the set according to the invention.

A further advantage of the invention may be that production and storage of housing and/or sliding element in large quantities in only one design is of course easier.

The at least one damping element can serve, in the mounted state, to at least partially dampen and/or cushion relative movements such as vibrations and the like between the housing of the sliding guide shoe and/or the load basket and/or the cabin and/or the counterweight of the elevator on the one hand and the rail element on the other hand.

By means of a damping element designed according to the invention, in particular a separate one, the Damping quality can be well adjusted and adapted to the individual situation. This means that, for example, for passenger elevators, damping elements can be used that have low damping for small deflections and greater damping for larger deflections in order to allow good travel comfort in the cabin.

It should be noted that the damping element does not have to have exclusively damping properties. In certain applications, spring properties can be advantageous as an alternative or in addition. These can also be individually adapted by at least one damping element designed according to the invention, in particular a separate one.

In the context of the invention, lifts can be understood as devices with the aid of which persons and/or loads can be transported by purely vertical movement or by movements with a vertical component.

For this purpose, they can preferably have a load basket and/or a cabin and/or a counterweight to which the sliding guide shoe according to the invention can be attached.

By means of the guiding interaction of the sliding guide shoe with the rail elements, which are mounted, for example, in an elevator shaft, the load basket and/or the cabin and/or the counterweight can be guided.

The term "housing" in the context of the invention does not necessarily mean a housing that encloses or closes a volume. In the context of the present In the invention, the housing can be understood as simply a base body with a guide recess, which can be attached in any conceivable way to a load basket and/or a cabin and/or a counterweight in order to realize the guide mentioned.

The housing can preferably be designed in one piece. In other embodiments according to the invention, it can consist of two or more components which are, for example, plugged together.

In the assembled state of the sliding guide shoe and the elevator, a rail element is accommodated in the guide recess in the housing, wherein the sliding element is arranged in the guide recess such that the sliding element is guided in a sliding manner on the rail element. At least one damping element is provided between the sliding element and the housing.

It should be noted that the housing does not have to enclose the at least one damping element, let alone completely enclose it. In preferred embodiments, a damping element, preferably a damping element arranged on a basal sliding surface, can also directly contact a load basket and/or a cabin and/or a counterweight instead of the housing from the inside.

The sliding element components can be arranged in different relative positions to each other in order to accommodate differently designed, preferably differently thick, rail elements. The relative positions can be a few discrete relative positions that correspond to common rail elements or there can be continuously shiftable relative positions so that by appropriate Damping elements can cover a continuum of relative positions and rail geometries.

The fact that the relative position of the sliding element components is at least partially determined by the at least one damping element can be understood to mean that, for example, the sliding element components can in principle be moved further towards one another than is fundamentally determined by the at least one damping element, for example when there is a gap between the sliding element components and the rail elements or the sliding guide shoe is not mounted.

Optional spacers, such as washers, can be used to at least partially determine the relative position of the sliding element components. Such spacers could be used, for example, if the sliding element is already subject to a certain amount of wear in order to eliminate or at least reduce any play.

According to the invention, the entirety of the sliding element components is referred to as a sliding element.

In preferred embodiments, the at least one damping element can be designed, for example by means of plug connections, such that the relative position of the sliding element components is completely determined by the at least one damping element.

According to the invention, the rail elements are guided by the sliding guide shoe, viewed in the rest system of the housing and/or the load basket and/or the cabin and/or of the counterweight. It is clear to experts that, viewed from the outside, the guide shoe and/or the load basket and/or the cabin and/or the counterweight of the lift are guided on the rail elements.

It should be noted that the recess in the base body according to the invention does not have to be a blind hole or the like. Rather, this expression covers any housing shape that allows the sliding element to be at least partially accommodated in such a way that the rail elements in the recess can be guided by the sliding element.

Advantageous developments of the invention are defined in the dependent claims.

A thickness of the at least one damping element may be such that a clear width between the at least two sliding element components corresponds to a given thickness of a rail element, optionally plus a gap dimension or optionally minus a preload stroke.

Preloading the sliding guide can prevent noise, such as rattling, when the sliding element is already subject to a certain amount of wear.

The thickness of the at least one damping element can preferably be more than 5 mm. In particularly preferred embodiments, the thickness can be between 7 mm and 15 mm or between 9 mm and 14 mm.

The sliding element and/or the guide recess can have a U-shaped cross-section.

The sliding element components may each have a lateral sliding surface and a basal sliding surface, wherein a length of the basal sliding surface is shorter than a length of the lateral sliding surface, wherein the length of the basal sliding surface is preferably half or less than the length of the lateral sliding surface.

Embodiments wherein the length of the basal sliding surface is half the length of the lateral sliding surface may be particularly preferred because it is thereby easily possible to use complementary, substantially identical sliding element components that can be pushed into one another.

In embodiments wherein the at least one sliding element has a U-shaped cross-section, the lower inner surface can preferably be referred to as the basal sliding surface and/or the lateral inner surfaces as the lateral sliding surfaces.

The clear width can preferably be measured or present between the lateral sliding surfaces, for example if the sliding element has a U-shaped cross-section.

The sliding element can have exactly two sliding element components, which are preferably identical.

Alternatively, the sliding element components may be symmetrical and otherwise substantially identical and/or may be designed to be complementary to one another such that the different relative positions can be achieved by sliding them into one another.

Of course, designs with more than two sliding element components are also conceivable.

Sliding element components are considered to be "essentially" the same if the basic structure is the same (or mirrored) and/or their functional elements are constructed in the same way and/or have the same geometries except for manufacturing tolerances.

In particularly preferred embodiments, the sliding element components can be designed to be complementary to one another such that the different relative positions can be achieved by sliding them into one another parallel to the basal sliding surfaces.

Film hinges may be present between the basal sliding surfaces and the lateral sliding surfaces, for example in order to be able to realize the U-shaped cross-section when arranged in the guide recess.

The at least one damping element can be connected or connectable to the sliding element components via at least one plug connection. As already mentioned, this makes it possible to achieve a predetermined relative position of the sliding element components (complete specification of the relative positions of the sliding element components).

Plug-in connections can also have the advantage that forces can be distributed into at least one damping element, which can improve the damping properties.

In particularly preferred embodiments, the at least one damping element can be a damping element for a basal Sliding surface and/or a damping element for lateral sliding surfaces, ie the basal sliding surfaces of the sliding element components naturally form the basal sliding surface of the sliding element.

In particularly preferred embodiments, exactly three damping elements can be present in one set, namely, for example, one damping element for a basal sliding surface and one damping element each for lateral sliding surfaces.

Of course, other combinations or arrangements of one or more damping elements can also be used.

The rail elements and/or the sliding element can be connected to the housing and/or a load basket and/or a cabin and/or a counterweight of the elevator exclusively via the at least one damping element, i.e. there are no mechanical bridges via which vibrations or other relative movements can be transmitted from the sliding element and/or the rail element to the housing, the load basket, the counterweight and/or the cabin.

The housing and/or the sliding element and/or the sliding element components and/or the at least one damping element can be designed separately from one another, i.e. form separate parts or components. In other words, the elements mentioned are not permanently connected or part of a composite body, but are manufactured separately from one another and/or can be disassembled without causing damage.

The at least one damping element can be made of a damping material and/or have recesses.

Through these measures, the damping properties can be tailored specifically to the respective application, as already mentioned.

The at least one damping element can be mounted at a distance from the housing in such a way that a deflection occurs when the at least one damping element is deformed. This makes it particularly easy to achieve a good response behavior of the at least one damping element for small deflections.

This spacing can be achieved, for example, by means of raised bearing points for the at least one damping element. However, such elevations do not have to be arranged on the housing, but can also be present on the at least one damping element.

The mentioned spacing does not mean that the housing and the damping element must not touch. Rather, it means that the connection of at least one damping element to the housing, whatever it is, is such that the mentioned deflection can take place.

In preferred embodiments, the damping elements (or further damping elements) are designed such that they produce progressive damping, i.e., as the applied force increases, a non-linearly greater damping effect results.

Particularly preferred is to use recesses in the damper body, whose adjacent material parts act as spring tongues that are subjected to bending. If the acting force is then so high, If the recesses are closed, this effect of the spring tongues would be eliminated and only the damping of the material itself would remain. Such progressively acting damping elements can be used as an alternative to or in addition to the aforementioned mounting of the damping elements at a distance from the housing.

Alternatively or additionally, it can be provided that the at least one damping element contains a joint, preferably in the form of a solid-state joint. This enables the sliding element to be pressed against the rail element over its entire surface, even if, for example, the cabin is at an angle due to asymmetrical loading and the sliding guide shoe is thus aligned at an angle to the rail element.

A further additional or alternative possibility for realizing progressively damping damping elements is to realize the damping elements in two or more parts, wherein a first sub-damping element and a second sub-damping element are spaced apart from each other such that at least one or a part of a sub-damping element is subjected to bending and/or compression under the action of force.

If the force becomes so great that the first sub-damping element and the second sub-damping element come into contact over the entire surface (i.e. not only at the bearing points), progressive damping occurs again because then only the damping of the materials of the first sub-damping element and the second sub-damping element takes effect.

It can preferably be provided that the first sub-damping element is made of a material with other damping properties than the second sub-damping element (e.g. one with harder damping than the other).

The housing, the sliding element, the sliding element components and/or the damping element can be made of plastic, preferably using an injection molding process. In other designs, a metal can be used as the material instead, partially or completely.

When manufacturing the housing, bushing inserts (e.g. made of metal with a through hole) or threaded inserts are particularly preferred so that the sliding guide shoe can be mounted via threads on the load basket, the cabin or the counterweight of the elevator.

Embodiments may be particularly preferred in which the housing has an opening facing away from the guide recess, via which the sliding element can be inserted into the housing together with the at least one damping element.

A base body of the housing can be made, for example, from a polyamide and/or polyoxymethylene.

The housing may have a base body reinforced with fibres or particles (generally fillers), for example with 50 vol.% admixture.

The fibers can be glass, mineral, carbon and/or basalt fibers.

The sliding element and/or the sliding element components can be made, for example, of a polyethylene and/or a Polyoxymethylene, whereby additives, reinforcing and/or fillers can of course optionally be used.

The at least one damping element can be made, for example, from a foamed or non-foamed plastic, wherein the foam is preferably closed-cell. The plastic of the at least one damping element can be, for example, a plastic, preferably a thermoplastic, preferably a polyurethane and/or an elastomer.

Fig.1 shows schematically an elevator 2, wherein the sliding guide shoe 1 according to the invention, for example according to Fig. 2a or according to Fig.6 can be used.

The elevator includes a cabin 12 (or a load basket or a counterweight) which is guided over rail elements 5. The travel axis of the elevator 2 is perpendicular to the drawing plane.

In order to realize the guidance, 12 sliding guide shoes 1 are mounted on the cabin, which interact with the rail elements 5.

Inventive embodiments for sliding guide shoes 1 are described below.

Fig. 2a and 2b show an embodiment of a sliding guide shoe 1 according to the invention in a perspective and a partially cut representation.

The sliding shoe includes a housing 3, a sliding element 6 and damping elements 7.

The sliding element 6 and the damping elements 7 are arranged in a guide recess 4 of the housing 3.

In the present embodiment, the sliding guide shoe is made of plastic using the injection molding process.

For mounting the sliding guide shoe 1, bushing inserts 16 are embedded in the housing 3 so that the mounting can be carried out by means of screw connections, whereby the bushings absorb the preload of the screws (and not the housing 3).

Alternatively or additionally, simple through-openings in the housing 3 can be used.

Fig. 3a and 3b show sectional views of the embodiment from the Fig. 2a and 2b .

It can be seen first of all that the sliding element 6 is realized by two sliding element components 8. From the comparison of the Figures 3a and 3b It can be seen that the sliding element components 8 can be moved relative to one another in the vertical direction in the drawing plane.

Also visible are three damping elements 7, which are dimensioned so that the sliding element components 8 assume a relative position so that a clear width between the at least two sliding element components 8 corresponds to a given thickness of a rail element 5. This dimensioning of the damping elements 7 is achieved here by the thickness d of the damping elements 7.

It can be seen that in the Figures 3a and 3b Rail elements 5 of different thicknesses are present. The thicknesses d of the damping elements 7 are clearly adapted such that the rail elements 5 are guided in the sliding element 6 formed by the sliding element components 8, wherein preferably no gap is provided, the rail elements are therefore guided under constant contact.

Optionally, a gap dimension or a pre-tension stroke can be provided.

The sliding element 6 formed by the sliding element components 8 has a U-shaped cross section. The sliding element 6 has a lateral sliding surface 9 and a basal sliding surface 10, with each sliding surface being assigned a damping element 7.

In alternative embodiments, the three damping elements 7 could, for example, be connected so that ultimately only a single damping element 7 would be present.

The housing 3 includes a rear opening 15 so that one of the damping elements 7 is in direct contact with the cabin 12.

It should be mentioned that the sliding element 6 in the form of the sliding element components 8 is mounted exclusively by the damping elements 7 in the housing, without bridges being present over which vibrations and the like from the sliding element 6 past the damping elements 7 into the housing 3 or onto the cabin 12.

In the Figures 4a to 4d different deformation states are shown for an exemplary possibility for mounting the damping elements 7 and the sliding element components 8.

The housing 3 has raised bearing points 13 on which the respective damping element in Fig. 4a shown undeformed state.

The sliding element components 8 are attached to the respective damping element 7 via a plug connection 11.

In the case of a deformation - for example due to a force acting from the right in the plane of the drawing on the sliding element component 8 - the deformation initially consists of a bending stress on the damping element 7, which in Fig. 4b can be recognized.

From a certain degree of deformation, the damping element 7 contacts the sliding element component 8 at the edge.

In case of even further deformation, the damping element 7 also contacts centrally the housing 3 (or the cabin 12 or the load basket or the counterweight), which in Fig. 4c From this point on, the damping effect of the material and, if necessary, a geometric structure of the damping elements (see Fig. 5a to 5d ) to wear (see Fig. 4d ).

Due to the raised bearing points 13 in the housing (and optionally the precise design of the plug connection 11 between the Damping element 7 and the sliding element component 8) can therefore create a situation in which the damping element 7 is initially only subjected to bending stress, which can produce a particularly good response of the damping for small deformations. Nevertheless, the damping is increased for larger deformations by the system on the housing 3 or the cabin 12 (or the load basket or the counterweight), so that overall a type of progressive damping curve results.

In addition, the maximum deformation of the damping element 7 can be determined by the shape of the housing 3, for example as in Fig. 4d the rail element would be in contact with the housing 3 at the desired maximum deformation. This was Fig. 4d dashed and indicated by the reference number 5.

This allows the damping element 7 to be protected because it cannot be compressed to the point of destruction.

Projections 25 (only in Fig. 4a provided with reference numerals) serve to prevent direct contact between the sliding element component 8 (or the sliding element 6 or the rail element 5) and the housing 3, so that no vibrations and the like are transmitted from the sliding element 6 or the rail element 5 to the housing 3.

However, such projections 25 are not always absolutely necessary if the lateral resistance of the bearings is large enough to prevent contact even without separate structures. Therefore, the Fig. 4e to 4h a version without the projections 25, which is otherwise completely analogous to that of the Figures 4a to 4d is.

The Figures 5a and 5b show various embodiments of damping elements 7, as they can be used in the invention, wherein in Fig. 5b and 5c A perspective and a partially sectioned view are shown.

Fig. 5a shows a damping element 7 which, for example, according to Fig. 3a and 3b is designed as a solid material part.

Fig. 5b to 5d show further designs with certain structures that can be used to achieve certain damping effects.

For example, in Fig. 5b and 5c recesses are used to achieve lower damping compared to the solid material part made of Fig. 5a to produce either a lower stiffness or a different response compared to the solid material part made of Fig. 5a or to generally use other special properties of other materials or manufacturing processes. For example, a material with high resistance to deformation but with a smaller cross-section / area moment of inertia can be combined to achieve the comparable or desired stiffness.

In Fig. 5d hump structures are used to achieve an even more progressive damping behavior. With small deformations, the hump structures will be easy to deform. With larger deformations, 7 deformations occur across the entire damping element, so that more energy is required overall for further deformations. In this way, a very good response and the aforementioned progressive damping behavior are created.

In the example from Fig. 5e Leaf spring-like connecting pieces are used.

In preferred embodiments, the damping elements 7 (or further damping elements 14) are designed in such a way that they produce progressive damping, i.e. that an increase in the acting force results in a non-linearly greater damping effect. Such designs are described in the Figures 5f to 5k Such progressively acting damping elements 7 can be used as an alternative or in addition to the mounting of the damping elements 7 at a distance from the housing, as shown in Fig. 4a to 4d is shown.

Particularly preferably, recesses 20 in the damper body can be used for this purpose, the adjacent material parts of which act as spring tongues 21 that are subjected to bending. If the force acting is then so high that the recesses are closed, this effect of the spring tongues is lost and only the damping of the material itself remains.

Particularly preferably, further spring tongues 22 can be provided, which are arranged on the inner sides of the recesses 20, for which purpose the Figures 5f and 5g is referred to.

The additional spring tongues prevent the recesses 20 from closing abruptly under the influence of force, but instead close progressively against the effect of the additional spring tongues 22. This means that the damping is not increased abruptly when the recesses 20 close, but only after the additional spring tongues 22 have completely deformed.

For reasons of clarity, only one recess 20, one spring tongue 21 and - if present - another spring tongue 22 were shown in the diagrams of the Figures 5f to 5i provided with reference symbols.

In addition, it is stated in the statements of the Figures 5f to 5i It is provided that the at least one damping element 7 includes a joint 26, here in the form of a solid-state joint. This enables the sliding element 6 to be pressed against the rail element 5 over its entire surface, even though, for example, the cabin is inclined due to asymmetrical loading and the sliding guide shoe 1 is thus aligned at an angle to the rail element 5.

The upper and lower spring tongues 21 (actually left and right in the illustration) in the Figures 5f and 5g are only connected in the middle with flexible webs or ribs, which form the joint 26.

The statements of the Figures 5h and 5i have between the two spring tensioners 21 the joint 26, which forms the pivot point at which, when unloaded, only one edge of the at least one damping element 7 contacts the housing 3.

Another possibility for realizing progressively damping damping elements 7 is to realize the damping elements 7 in two or more parts, wherein a first sub-damping element 23 and a second sub-damping element 24 are spaced apart from each other such that at least one or part of a sub-damping element 23 is subjected to bending and/or compression under the action of force. Examples of this are given in the Figures 5j and 5k shown.

If the force becomes so great that the first sub-damping element 23 and the second sub-damping element 24 come into contact over the entire surface (i.e. not only at the bearing points), progressive damping occurs again because then only the damping of the materials of the first sub-damping element 23 and the second sub-damping element 24 is effective.

It can preferably be provided that the first sub-damping element 23 is made of a material with different damping properties than the second sub-damping element 24.

The examples from the Figures 4a to 4d and the Figures 5a to 5k show that the invention can be used very well to adjust the damping behavior of the sliding guide shoe 1 as desired, without the need for complex adjustment options on the housing 3, the sliding element 6 and/or the cabin 12 (or the load basket or the counterweight).

One aspect of the invention is that the sliding guide shoe 1 according to the invention can be provided as a set with further damping elements 14, which differ in terms of dimensioning, in particular thickness d (see Fig. 3a and 3b ), or the damping properties of the damping elements 7 of the sliding guide shoe 1.

When assembling the lift 2, the personnel does not necessarily have to know in advance which rail elements 5 or which damping properties of the damping elements 7 are necessary. Rather, this can be easily determined on site using the set according to the invention and the suitable damping elements 7 are used in the sliding guide shoes 1.

Fig.6 shows an exploded view of another embodiment of a sliding guide shoe 1 according to the invention in an exploded view. The in itself as in the embodiment according to the Fig. 2a and 2b Structures with a housing 3, sliding element components 8 and damping elements 7 are also present here, but partly in a different geometric design.

Fig. 7a and 7b show a perspective view and a sectional view of the embodiment from Fig.6 .

The Figures 8a to 8c show the housing 3 of the embodiment from Fig.6 in different perspectives. The guide recess 4 is clearly visible.

The opening 15, which can be used to insert the sliding element 6 and the damping elements 7, is also clearly visible.

In this embodiment, the opening 15 is essentially full-surface, i.e. the housing is open towards the cabin 12 (or the load basket or the counterweight) in the assembled state.

Fig. 9a and 9b show a top view and a sectional view of the Fig. 8a to 8c shown housing.

Fig. 10a to 10d show a sliding element component 8 as in the embodiment according to Fig. 2a and 2b or at Example according to Fig.6 could be used in different perspectives.

The sliding element component 8 has, as mentioned, a lateral sliding surface 9 and a basal sliding surface 10, wherein a length of the basal sliding surface 10 is half of the lateral sliding surface 9.

In preferred embodiments (as in Fig.2a and 2b or Fig.6 ), the sliding element 6 has exactly two identical sliding element components 8, which are arranged in the housing 3 rotated relative to one another and engage with one another.

Alternatively, the sliding element components 8 could be symmetrical to one another and otherwise essentially identical.

The sliding element components 8 are furthermore designed to be complementary to one another so that the different relative positions can be achieved by sliding them into one another parallel to the basal sliding surfaces 10. In this regard, reference is made to the comparison of the Figures 3a and 3b with the Figures 10a to 10d to refer to.

In Fig. 10b and 10d a pin element of a plug connection 11 can be seen, by means of which the sliding element component 8 with, for example, the basal damping element 7 (each in the drawing plane on the left in Fig. 3a and 3b ) can be connected.

For this purpose, the counterparts to the pin elements, for example in the form of holes, can be positioned in the basal damping element 7 in such a way that the correct Relative position between the sliding element components 8 (see Fig.6 and Fig. 11c ).

It should be mentioned that the sliding element component 8 can be manufactured particularly easily in this exemplary embodiment. Firstly, it can be molded in a flat configuration by an injection molding process and then folded along the film hinge 17 so that in the configuration of the Fig. 10a to Fig. 10c is available and can be used as described.

Fig. 10e shows a further embodiment of a sliding element 6 consisting of two sliding element components 8. The basal sliding surface 10 is realized by divided surfaces on the sliding element components 8, ie the basal sliding surface 10 of a sliding element component does not have to be continuous. (The same applies, of course, to the lateral sliding surface 9).

Fig. 11a to 11d show a damping element made of Fig. 4a to 4d and 5a alternative damping element 7, as in the embodiment according to Fig. 2a and 2b or in the embodiment according to Fig.6 or could be used in the set according to the invention as a further damping element 14, in different perspectives.

The damping element 7 shown here has a thickness d of 12.5 mm for certain rail elements 5. For certain other rail elements 7, the thickness d of the damping element 7 could be, for example, 9.5 mm.

In the Figures 12a to 12f Further embodiments for sliding elements 6 and sliding element components 8 are shown.

Fig. 12a and 12b show an embodiment wherein the basal sliding surface 10 and/or the lateral sliding surface 9 are provided with grooves or channels.

This can reduce noise and vibrations (similar to a disc brake).

Fig. 12c and 12d show an embodiment, wherein the sliding element 6 consists of three sliding element components 8, which are designed separately from one another.

Fig. 12e and 12f also show an embodiment in which the sliding element 6 consists of three sliding element components 8, which are not designed separately from one another, but are connected to one another via connecting sections 18. The connecting sections 18 are designed with such thin walls that the individual sliding element components 8 can be brought into the desired relative position to one another.

The embodiments shown here show sliding element components 8 which can be brought into the desired relative position by linear displacement, in particular by pushing them into one another. In alternative embodiments, the different relative positions can in principle also be achieved by pivoting them towards one another or pushing them into one another along a curved path.

Like the Fig. 12e and 12f As can be seen, the sliding element components 8 in the sense of the invention do not have to be realized as completely separate components. According to the invention, the sliding element components 8 only have to be arranged in different relative positions to each other be able to be adapted to different geometries, in particular thicknesses, of the rail elements 5.
