As a result, it may be possible to improve a compromise with regard to production-related variations and the simplest possible manufacture and assembly.

Description

Embodiments relate to a profile slider, a lifting column and a method for mounting a lifting column.

Profile elements are used in a variety of technical applications. Thus, the profile elements comprise, for example, profile tubes, lifting column elements and other profiled components with which, for example, a mechanical alignment, a transport or another movement of an object in the room is made possible. Thus, in such applications often individual profile elements are moved linearly to each other.

This technically often presents the challenge of implementing a guidance of the relevant profile elements to one another. In such a guide, therefore, a movement of the profile elements which is as low as possible or even friction-free along a direction of movement is desired, while movement of these elements relative to one another is to be prevented in a direction different from the direction of movement of the profile elements involved. Along such a direction, a force can thus be exerted by one component on the other by a corresponding implementation of a bearing, whereas this should be prevented as far as possible along the direction of movement.

A technical possibility to implement such a storage is at least partially to implement a sliding bearing.

For example, the components used may have variations and tolerances as a result of production or due to other circumstances, which should be taken into account when assembling the components to form a larger system or assembly, for example, not detrimental to functional reliability, reliability or even a sense of comfort for a user to influence. Irrespective of this, in the production and assembly of such an assembly or such a system as simple and thus possibly cost-effective production but also in the foreground.

In the case of profile elements, for example, a sliding bearing of the same relative to one another is realized with the aid of profile gliders, which for example slide on corresponding guide surfaces and are in contact therewith. Depending on the profile for which application corresponding profile elements are provided, for example, an insufficient consideration of tolerances and play can lead to a failure of a corresponding unit or even to a perceived by the user as unpleasant development of noise or other problems. Corresponding profile elements can be used for example in lifting columns, as used for example in machine tools as well as medical devices. However, similar challenges are by no means limited to the mentioned fields of application.

There is therefore a need to improve a compromise in terms of manufacturing variations and the simplest possible manufacture and assembly.

This requirement is borne by a profile slider according to claim 1, a lifting column according to claim 8 and a method for mounting a lifting column according to claim 10.

A tread glider according to an embodiment for linearly guiding a tread element relative to another tread element with respect to a direction of movement is adapted to be attached to the tread element, the tread glider being further configured to be resiliently formed with a guide surface of a guide groove and one of the guide surface opposite arranged further guide surface of the guide groove of the other profile element to be in contact. The guide surface and the further guide surface may, for example, be perpendicular to the direction of movement.

A lifting column according to an exemplary embodiment comprises a profile element, a further profile element which is movable relative to the profile element along a direction of movement and has a guide groove with a guide surface and a guide surface opposite arranged further guide surface, and at least one profile slider according to an embodiment of the Attached profile element and is arranged so that the at least one profile slider is in contact with the guide surface and the further guide surface of the guide groove of the further profile element.

A method according to an embodiment for mounting a lifting column comprises attaching a profile slider to a profile element and at least partially introducing the profile slider in a guide groove of another profile element which is movable relative to the profile element with respect to a movement direction and a guide surface and a guide surface arranged opposite further guide surface of the guide groove, wherein the profile slider elastically deformed to be in contact with the guide surface and the further guide surface.

Embodiments is thus based on the finding that a compromise with respect to production-related variations and the simplest possible manufacture and assembly can be improved by a profile slider is used, which by a flexible or elastic deformation of the guide surface and the other guide surface of Guide groove applies so as to allow the linear guidance of the profile element relative to the further profile element. As a result of the flexible or elastic deformation, a substantially disassembly-free installation process can thus be realized even if the guide surface is only approximately known, which can lead to a substantially play-free guidance of the profile elements relative to one another by the profile slider.

Thus, by way of example, compensating for a change in the distance between the guide surface of the guide groove and the further guide surface of the guide groove can be compensated or adapted by means of a profile slider, for example.

The direction of movement can represent a structurally predetermined direction. This can be predetermined for example by the profile element and / or the further profile element. For example, the direction of movement may be determined by a profile of the guide groove. Despite the word component "direction", the individual "directions" in the present case may not necessarily be a direction in the mathematical sense of a vector, but a line along which the corresponding movement takes place. Such a line can be straight but also bent. Abgrenzenzenzen here are directions that actually describe directions along a line, such as the direction of movement. For example, a first direction may be opposite to a second direction, but both may run or be directed along a line also referred to as a "direction".

Optionally, a profile slider according to an embodiment may be formed to simultaneously be in contact with the guide surface and the further guide surface of the guide groove. This makes it possible to enable a play-free guidance of the profile elements to each other. Alternatively or additionally, it may also be possible, for example, for a rotational movement or rotational load impressed from the outside, to allow for a noise-reduced and possibly more pleasant sound development. It is also possible, if appropriate, to avoid or at least reduce an otherwise otherwise not technically harmful, but unpleasant, noise development during a torsional movement of the profile elements relative to one another.

Additionally or alternatively, a profile slider according to an embodiment, a guide structure and a mounting structure, wherein the mounting structure is formed to be attached to the profile element. The guide structure can be elastically deformable perpendicular to the direction of movement. It may thus be possible, for example, an elastic deformability based on the attachment structure. This may possibly make it possible to implement a corresponding profile slider with technically simple means.

Optionally, in such a profile slider according to an embodiment, the guide structure have a lower elastic deformability along the direction of movement, as perpendicular to this. This makes it possible to derive forces occurring along the direction of movement via the attachment structure into the profile element. Thus, optionally, the elastic deformability along the direction of movement, for example by at least a factor of 2, by at least a factor of 5 or by at least a factor 10 may be smaller than perpendicular to this. In this context, elastically deformability of the profile slider along a direction in which the force acts on the profile slider may, for example, be based on the introduced force.

Additionally or alternatively, in a profile slider according to an embodiment, the guide structure in an unloaded basic position with respect to the direction of movement may be formed substantially symmetrically. This may make it possible to reduce the occurrence of the shear loads and other forces and torques which load the profile slider more heavily. In addition, it may possibly also be possible to simplify installation of the profile slider, since this may possibly be installed due to the symmetry in more than one position.

For example, a component may have n-fold rotational symmetry, where n is a natural number greater than or equal to 2. An n-fold rotational symmetry is present when the component in question, for example, about a rotational or symmetry axis by (360 ° / n) is rotatable and thereby merges substantially in terms of form in itself, ie with a corresponding rotation substantially to itself in the mathematical sense is mapped. In contrast, in a complete rotationally symmetrical embodiment of a component in any rotation about any angle about the axis of rotation or symmetry, the component essentially in terms of form, so in the mathematical sense it is essentially modeled on itself. Both an n-fold rotational symmetry as well as a complete rotational symmetry are referred to here as rotational symmetry or symmetry.

Additionally or alternatively, in a profile slider according to an embodiment, the guide structure may be formed to start from an unloaded home position a distance between a sliding surface of the guide structure, which in turn is formed to be in contact with the guide surface, and another sliding surface of the guide structure, which in turn is designed to be in contact with the further guide surface, to downsize. This makes it possible to even during operation, for example due to an operating position or a temperature change, compensate for changes in distance between the guide surface and the other guide surface, provided that their distance regardless of the changes in operating parameters is smaller than the distance of the sliding surface of the other sliding surface in the unloaded basic position of the profile glider.

Additionally or alternatively, a profile slider according to an embodiment may be formed substantially symmetrically with respect to the direction of movement. Thus, for example, not only the guide structure but the complete profile slider can be designed symmetrically. This may make it possible, in addition to the previously described reduction of unfavorable loads of the profile slide so possibly also the installation or the attachment of the profile slider can be further simplified in the profile element, as a false assembly of the profile slider is unlikely.

Optionally, according to one embodiment, a lifting column may further comprise a drive unit which is designed to move the profile element relative to the further profile element. As a result, it may thus be possible to integrate not only a pure mobility but also actuation skills in the lifting column.

Optionally, in such a lifting column according to an embodiment, the drive unit comprises a motor, for example an electric motor, a pneumatic motor or a hydraulic motor, which is designed to set a shaft in a rotational movement. Optionally, moreover, the drive unit further comprise a helical gear, for example a spindle drive or a worm drive, which is designed to convert the rotational movement of the motor or the shaft into a linear movement along the direction of movement. This makes it possible to implement a drive concept with structurally simple means. Due to the fact that the motor generates a rotational movement with respect to the shaft, however, such a system may cause the lifting column to impose an angular momentum which leads to a rotation about the direction of movement of the profiled element relative to the further profiled element. Especially in such a scenario, the use of a profile slider according to an exemplary embodiment due to its elastic deformability and its associated optionally playable leadership of the profile elements each other to a low-wear, more reliable, more resilient and / or quieter movement of the profile elements contribute to each other.

Adjacent are two objects, between which no further object of the same type is arranged. Immediately adjacent are corresponding objects when they are adjacent, that is, for example, in contact with each other. Under an integrally formed component is understood as one which is made exactly from a contiguous piece of material. An integrally manufactured, provided or manufactured component or structure or a component or structure produced, prepared or manufactured integrally with at least one further component or structure is understood to mean one which, without destroying or damaging one of the at least two components involved, is not affected by the at least another component can be separated. A one-piece component thus also represents at least one component manufactured integrally with another structure of the relevant component or one-piece component.

A frictional contact or a frictional connection is when two objects frictionally contact each other, so that between them a force in the case of a relative movement perpendicular to a contact surface between them arises, which allows a transmission of a force, a rotational movement or a torque. Here, a speed difference, so for example, a slip exist. In addition to such a frictional contact, however, a frictional contact also includes a frictional or non-positive connection between the objects in question, in which a corresponding speed difference or slip substantially does not occur.

A frictional or frictional connection comes about through static friction, a cohesive connection by molecular or atomic interactions and forces and a positive connection by a geometric connection of the respective connection partners. The Stiction thus generally requires a normal force component between the two connection partners.

In one embodiment of a method, the aforementioned method steps in the specified, but also optionally in a different order can be performed. Thus, if appropriate, individual process steps can take place simultaneously, but at least overlap in time, unless otherwise stated in the description or the technical context.

Hereinafter, embodiments will be described and explained in more detail with reference to the accompanying drawings.

In the following description of the accompanying drawings, like reference characters designate like or similar components. Further, summary reference numbers are used for components and objects that occur multiple times in one embodiment or in one representation, but are described together in terms of one or more features. Components or objects which are described by the same or by the same reference numerals may be the same, but possibly also different, in terms of individual, several or all features, for example their dimensions, unless otherwise explicitly or implicitly stated in the description.

As already explained, profile elements, for example profile tubes, lifting column elements and other corresponding profiled components, are used in many areas of technology for the alignment, movement or arrangement of objects, components, animals or humans. Thus, corresponding profile elements are used, for example, in machine tools as well as in the medical field.

Profile elements in this case often have manufacturing-related, treatment-related or other-related deviations from a Sollmaßauftreten, which may be tolerances, but may be considered in the assembly of the profile elements to a larger unit, such as an assembly or a system, for example, a functionality or even to improve comfort. Thus, for example, the functionality can diminish prematurely especially with a longer operation or completely lost. Consideration of such variations, which themselves correspond to the tolerance, can thus be relevant for the reliability.

But even if the reliability or the functionality should not be endangered, for example, noises may arise through corresponding variations, which are perceived by a user as unpleasant, for example, as a lack of reliability suggestive.

To guide profile elements to each other in this case, for example, plain bearing techniques can be used. One way to implement such a plain bearing, is the use of profile glides. So these can be used for example for the guidance of telescopic profile elements, profile tubes, Hubsäulenelementen or other profiled components. Here, the profiled components often along a main extension direction to an extent which is greater than that of the other spatial directions, with corresponding guide structures, such as a guide groove in which such a profile slider runs, at least partially extend along this main extension direction. The direction of such a guide groove can for example predetermine or determine the direction of movement along which the profile elements move relative to one another.

To compensate for variations that can be perfectly tolerant, conventionally different profile glides are used with different widths to compensate for these tolerances can.

In contrast, with the aid of a profile slider according to one example, a tolerance compensation due to its elastic deformability allow. Such a profile slider is therefore also referred to as a tolerance compensating profile slider or resilient profile slider, which may possibly allow a backlash-free installation in a profile element, such as a profile tube, a Hubsäulenelement or another profiled component.

These tolerance-compensating profile glides can for example compensate for a certain range of a tolerance field between the guide surfaces of the profile elements, also referred to as sliding surfaces, and an angular offset of the guide groove, also referred to as profile groove. In this way it may be possible to achieve freedom from play in a profile element set, which is also referred to as a profile tube set, without having to use profile gliders of different widths. Such a profile slider, for example, comprise only a single plastic part and can thus reduce a variety of the individual, different width single profile slider with a fixed width.

Profile glides, as described below, can be used for example in lifting columns with a corresponding sliding system for guidance. These are tolerance-compensating profile slides for lifting columns, which can be optionally supplemented with actuators and corresponding actuator systems, as the following description will also show.

Profile sliders, however, are far from being limited to lifting columns, but can in principle be used in all systems in which, for example, two profile elements are at least partially guided to each other by means of a plain bearing. Examples of corresponding applications include, among others, the field of machine tools, but also of medical application technology.

A profile slider can be used for example for a linear guide, so a linear guide. It should be noted that even in the case of a linear guide or linear guide, non-linear movements can certainly be encompassed if, for example, the relevant structures are bent to guide or have other corresponding contours. But profile glides can also be used for the storage of rotational movements. Accordingly, bearings can be implemented, for example, as a linear bearing or as a bearing for guiding rotational movements.

The 1 and 2 each show perspective views of a resilient profile slider as an example of a profile slider 100 , This can for example be made in one piece from a plastic, such as polyoxymethylene (POM) or a corresponding material. However, it can also be made in several parts or in one piece, but as a comprehensive material. For example, this can be produced as an injection-molded component, but also comprise a stiffening structure to which the corresponding structures of the profile slider are applied in a form-fitting, cohesive and / or non-positive manner and are fastened thereto.

The profile glider 100 has a fastening structure 110 with the help of which he at the in the 1 and 2 not shown profile element can be attached. The attachment structure 110 points at the in the 1 and 2 shown example, a cylindrical outer contour. More specifically, the attachment structure is designed here as a hollow cylinder or cup-shaped and has such, for example 2 shows a central recess 120 possibly making the attachment structure more elastic, making it easier to insert into a corresponding, in 1 and 2 not shown fastening opening can be introduced, in which the profile slider 100 then, for example, held positively and / or positively.

The profile glider 100 also has a management structure 130 on that with the attachment structure 110 via a connecting section 140 connected is. The connecting section 140 here has a bar-like structure, which on one of the guide structure 130 facing side of the attachment structure 110 this closes and so the central recess 120 designed like a blind hole. Of course, such structural details, however, in other examples of a profile slider 100 also be solved and implemented elsewhere.

The aforementioned beam-like portion of the connecting portion 140 sits down as a bar-like section 150 also in the management structure 130 continues and runs in this substantially parallel to a direction of movement 160 regarding those in the 1 and 2 not shown profile elements are movable or movable. Next to the bar-like section 150 the management structure 130 this is the example of a profile glider shown here 100 configured substantially annular, thus has an annular outer portion 170 on which two flattened areas 180-1 . 180-2 comprising, whereby on an outer contour of the annular outer portion 170 the management structure 130 sliding surfaces 190-1 . 190-2 are formed, which are just designed and intended to be in contact with corresponding guide surfaces of a guide groove of the profile elements, which by means of the profile slider 100 linear with respect to the direction of movement 160 should be led.

As already explained above, the bar-like section runs 150 the management structure 130 along the direction of movement 160 , ie parallel to the sliding surfaces 190 and the flattened areas 180 , There, where the bar-like section 150 in the annular section 170 the management structure 130 opens, so is a thickening material outside the bar-like section 150 formed, creating an elasticity of the profile slider 100 along the direction of movement 160 on a the material of the profile glider 100 or the management structure 130 own elasticity or deformability is limited. So it is in this direction related to the management structure 130 essentially a solid material.

In contrast, on both sides of the bar-like section 150 on the two flattened areas 180 between these and the bar-like section 150 each recesses 200-1 . 200-2 arranged, which at one of the flattened areas 180 near contour have a cylinder segment shape. In interaction with the flattened areas 180 This results in a material thickness compared to the other areas of the annular portion 170 reduced material thickness. Due to the annular configuration of the annular outer portion 170 and the additional material reduction in the area of the flattened areas 180 Thus, the profile slider in a direction perpendicular to the direction of movement 160 and perpendicular to a major axis 210 of the attachment section 110 higher ductility. Depending on the specific implementation, this may be, for example, at least twice, at least five times or at least ten times that of the deformability of the profile slider 100 or the management structure 130 along the direction of movement 160 correspond.

As a material can in principle in the case of a one-piece profiled slider 100 each elastic material is used, which under a compressive stress, as in 1 through the arrows 220 is indicated, to a deformation or elastic deformation of the guide structure 130 of the profile glider 100 leads, so the sliding surfaces 190 change in terms of their distance. This allows the profile slider 100 at least partially inserting into a guide groove of a profile element both by means of the sliding surface 190-1 , as with the other sliding surface 190-2 with corresponding guide surfaces of the guide groove are in contact, so as to the linear guide of the profile element with the guide groove relative to the profile element, with which the profile slider 100 about the attachment structure 110 is attached to effect. This is in a suitable embodiment of the profile slider 100 So, for example, with a correct dimension based on the guide, both the sliding surface 190-1 as well as the sliding surface 190-2 at the same time in contact with the respective guide surfaces of the guide groove. As explained here is the management structure 130 just capable of referring to the mounting structure 110 perpendicular to the direction of movement 160 to be elastically deformable.

profile Glide 100 Thus, in principle, they can be made of any material which allows elastic deformability in the manner described. In the case of a single-piece profile glider 100 Thus, the material from which it is made, the necessary elasticity or elastic deformability thereby have, that this is a corresponding plastic. As a plastic, for example, polyoxymethylene (POM) can be used.

In the in the 1 and 2 shown profile glides 100 is both the profile glider 100 as well as the management structure 130 with the bar-like section 150 and the annular outer portion 170 in an unloaded state or a basic position substantially symmetrical to the direction of movement 160 designed. As already mentioned in connection with the discussion of the arrows 220 illustrated force or pressure on the management structure 130 , With such a construction, the guide structure, starting from the unloaded basic position, a distance between the sliding surfaces 190 to downsize.

Of course, in other examples of a profile glide 100 many design features, such as the exact design and geometry of the recesses 200 and other parameters.

By using such a profile glider 100 , as shown in the aforementioned figures, for example, so possibly a simpler installation and a saving of parts can be realized. profile Glide 100 Here are not only on lifting columns, as in the following in connection with the 3 and 4 be described in more detail, limited, but can be used in many different systems are used. The profile slider or short slider is here often in the non-installed state, ie in the unloaded ground state, wider than the sliding groove also called guide in the profile elements, so for example in a corresponding profile tube or Hubsäulenelement. The sliding surfaces 190 of the profile glider 100 can be designed flexible and so with an installation of the profile slider 100 give in and thus adjust to the given Profilnutbreite. As a result, in contrast to profile gliders with a rigid construction possibly the provision of different width profile glides can be avoided.

3 shows an exploded perspective view of a lifting column 300 with a profile element 310-1 , which mounting holes 320 has, in the example profile slider 100 , as described above can be used. The profile element 310-1 here has several corresponding mounting holes 320 on, in the corresponding in each case a profile slider 100 can be used. 3 shows here due to the perspective chosen there only a mounting hole 320 , but shows due to the exploded view two profile slider 100-1 . 100-2 ,

The lifting column 300 further summarizes another profile element 310-2 on, which along the direction of movement 160 relative to the profile element 310-1 is movable. To the relevant linear guide over the profile or the profile 100 to allow so has the other profile element 310-2 at one of the profile element 310-1 facing side one or more Führungsnute 330 on. These each have lateral guide surfaces 340-1 . 340-2 on, the - due to the mobility of the two profile elements 310 along the direction of movement 160 - Are aligned parallel to the direction of movement and are perpendicular to this opposite. At the in 3 shown lifting column 300 are the profile elements 310 designed substantially cylindrical or hollow cylindrical, so that the relevant direction, relative to the guide surfaces are perpendicular to the circumferential direction of the cylinder shape.

As already described above, it is now possible for the profile slider to be attached via the fastening structure 110 and the mounting hole 320 with the profile element 310-1 be connected while the sliding surfaces 190 the management structure 130 with the guide surfaces 340 the guide groove 330 stay in contact.

Of course, in other examples of lifting columns also differently shaped profile elements 310 , differently shaped Führungsnute 330 or other design parameters are changed. For example, the number of profile glides 100 be adjusted arbitrarily. Also, other structures for attaching the profile glides 100 as the in 3 shown mounting holes 320 be used. Likewise, of course, the roles of the two profile elements 310 be reversed in terms of their arrangement inside-outside.

4 shows a schematic block diagram of an example of a lifting column 300 , which in turn is a profile element 310-1 and another profile element 310-2 has, in which case again the profile element 310 at least partially radially inwardly of the further profile element 310-2 is designed. The profile elements 310 may be referred to in connection with lifting columns, for example, as Hubsäulenelemente.

Again, the lifting column 300 again at least one profile slider 100 on that with the profile element 310-1 connected or attached to this. More specifically, this shows 4 two profile glides 100-1 . 100-2 Of course, the lifting column can also comprise further profile glides.

The profile glides 100 run in guide grooves 330-1 . 330-2 the further profile element and in this case lead to a movement of the two profile elements 310 to each other along the direction of movement 160 the two profile elements 310 to each other.

In order not only to allow a linear guidance of the profile elements to each other, but also to allow an active movement of the profile elements to each other, has the profile column 300 as they are in 4 is shown, further a drive unit 350 on which is capable of, the profile element 310-1 relative to the further profile element 310-2 to move. For this purpose, the drive unit 350 an engine 360 on, which may be, for example, an electric motor, a hydraulic motor or a pneumatic motor. The motor 360 This is designed so that this one wave 370 can put in a rotational movement. To this rotational movement in a linear movement along the direction of movement 160 implement, has the drive unit 350 Furthermore, a helical gear 380 on, which is just this able. The helical gear 380 may for example comprise a spindle drive or a worm drive. Depending on the specific implementation of the engine 360 for example, on a floor plate 390 be arranged with the also the profile element 310-1 or the other profile element 310-2 connected is. At the in 4 shown example of a lifting column 300 this is the other profile element 310-2 that with the bottom plate 390 connected is.

Of course, the aforementioned variations can also be implemented here, which include, for example, the number of profile sliders and other corresponding parameters.

5 finally shows a flowchart of a method for mounting a lifting column 300 , This includes in a process P100 fixing a profile slider 100 on a profile element 310-1 , In a process P110, the profile slider becomes at least partially 100 in a guide groove of another profile element 310-2 introduced, which with respect to the direction of movement 160 relative to the profile element 310-1 is movable and a guide surface 340 and one perpendicular to the direction of movement 160 from the guide surface 340 spaced apart further guide surface of the guide groove 330 having. In the at least partial introduction of the profile slider in the process p110, the profile slider 100 elastically deformed to fit with the guide surface 340 and the other guide surface in contact.

As has already been explained above, in this case, if necessary, the processes described above can take place in the described chronological sequence, in a reverse temporal sequence, overlapping in time or in parallel.

By using an exemplary embodiment, it may be possible to improve a compromise with regard to production-related variations and the simplest possible manufacture and assembly.

The features disclosed in the foregoing description, the appended claims and the appended figures may be taken to be and effect both individually and in any combination for the realization of an embodiment in its various forms.
