    Linear guidance device
    The invention relates to a linear guide device, comprising a guide rail extending in a longitudinal direction and connected to a support element, the guide rail being designed to support at least one guide carriage movable in the longitudinal direction.
    Linear guide devices (also called profile rail guides) of this kind consist accordingly of the guide carriage and the guide rails with respect to their main components. Profile rail guides are conventionally used such that one or more guide carriages are mounted on one or more guide rails. The rails and the carriages are usually connected to the respective component by means of screws.
    In the present case, it is a matter of connecting a guide rail to the supporting element that carries it. For this purpose - as mentioned - a connection by means of screws is usual. However, it is also known, for example, to use glue connections with which the guide rail is glued to the support element.
    In the latter case, among other things, the strength of the connection is problematic, although different materials can advantageously be connected to each other.
    Depending on the type of connection chosen between the guide rail and the support element, disadvantages must be taken into consideration. Sometimes the connection of different materials is problematic, sometimes the strength of the connection is not sufficient.
    The invention is therefore based on the object of further developing a linear guiding device of the type mentioned in the preamble such that it becomes possible in a simple, stable and economical manner to firmly connect the same and different materials to each other.
    The solution of this object by the invention is characterized in that the supporting element comprises a receiving part, in which a part of the guide rail is arranged, the receiving part comprising two opposite side surfaces, which lie opposite two side surfaces of the guide rail, at least one of which at least one elevation or at least one recess of the two side faces of the receiving part protruding in the direction of the side surface of the guide rail, at least one of the two side surfaces of the guiding rail comprising at least one elevation projecting in the direction of the side surface of the receiving part or at least one recess, wherein a fixing body extending in the longitudinal direction is provided between at least one of the side surfaces of the receiving part and at least one of the side surfaces of the guide rail in the region of the elevations or recesses.
    The fixing body can be in the form of a strip-shaped material part. It can also be designed as a thread or pin. It preferably consists of metal, in particular sheet steel.
    The guide rail can have a rectangular or square shape in cross-section perpendicular to the longitudinal direction, the receiving part in the supporting element then having a congruent rectangular or square shape in cross-section perpendicular to the longitudinal direction.
    At least one of the two side surfaces of the receiving part can have an elevation projecting in the direction of the side surface of the guide rail and the opposite side surface of the guide rail can have a recess that matches the elevation. In this case it is preferably provided that the surface of the elevation and of the recess is in a cross-section perpendicular to the longitudinal direction arcuate, in particular circular.
    However, it is alternatively also possible that at least one of the two side surfaces of the receiving part comprises an arcuate, in particular semi-circular recess and the opposite side surface of the guide rail an arcuate, in particular semi-circular, recess, wherein a fixing body with circular cross section (in in particular a wire or pin) is arranged in the recesses.
    The receiving part preferably comprises between the two opposite side surfaces a bottom surface which serves to support a support surface of the guide rail which is designed to be congruent with respect to the bottom surface and which is formed between the two side surfaces of the guide rail.
    A preferred embodiment of the invention is embodied such that a fixing body is arranged between only one side face of the receptacle and only one of the side faces of the guide rail.
    The invention is therefore directed to an attachment of profile rails to their bearing element via a depression of a fixing body, wherein the fixing body can be designed as a shaped component. The two components are preferably joined together by means of a separate connecting plate. The rail can therefore be form-fittingly connected to its bearing element by means of insert plates.
    This method of joining or assembling can result in considerable savings in costs, which would otherwise be incurred in particular in the preparation of the components. That is why the proposed process is particularly suitable for series components; the proposal according to the invention is further intended for applications in which the profile rail must be reliably connected to the bearing element over a greater length.
    Examples for the application of the proposed solution are guide rodless pneumatic cylinders with guides, driven linear modules, shafts and positioning tables, electric actuators of any kind with integrated guidance and short-stroke pneumatics, as well as electrical modules.
    Areas of application are, for example, operating tables and patient couches, but in general of course all types of linear sections in general machine and plant construction.
    Embodiments of the invention are shown in the drawing:
    FIG. 1 shows the section through a linear guide device, with a guide rail attached to a support element,
    FIG. 2 shows an enlarged portion of FIG. 1, namely the left, lower region of FIG. 1 in enlarged view,
    FIG. 3 shows in the representation according to FIG. 1 an alternative embodiment of the invention, and
    FIG. 4 shows in the representation in accordance with FIG. 1 a further alternative embodiment of the invention.
    In FIG. 1 shows a linear guiding device which comprises as a substantial component a guiding rail 2, which is mounted on a support element 3. The supporting element 3 can thereby be directly a machine bed. Furthermore, a guide carriage 4 (shown in broken lines) is provided on the guide rail 2, which carriage is slidably mounted on the guide rail 2 in a longitudinal direction L. The longitudinal direction L is perpendicular to the plane of all figures.
    For receiving or attaching the guide rail 2 to or in the support element 3, the support element 3 has a surface part rectangular receiving part 5. The receiving part 5 has two opposite side surfaces 6 and 7 and a bottom surface 14 situated between them.
    The guide rail 2 has a congruent shape, that is to say that it is in any case in the position shown in FIG. 1 lower part also has a substantially rectangular shape with two side surfaces 8 and 9 and a supporting surface 15 lying between them.
    When mounting or joining together the guide rail 2 and the support element 3, the guide rail 2 is moved in the direction of the arrow in FIG. 1 pressed or pressed into the receiving part 5. In order for a positive connection between the guide rail 2 and the support element 3 to be present after this joining process, the following embodiment is provided.
    The two side faces 6 and 7 of the receiving part 5 each have an elevation 10 projecting in the direction of the side face 8 and 9 respectively of the guide rail 2. The two side faces 8 and 9 of the guide rail 2 each have a recess 12. For the joining process in each case a fixing body 13 in the form of a strip of sheet steel (or can) extending in the longitudinal direction L against the side faces 8 and 9 of the guide rail 2 and the guide rail with the strip of sheet steel 13 in the receiving part 5 of the support element 3 pressed. Thus, according to the joining process, the strip of sheet steel 13 is arranged between the two side faces 6 and 7 of the receptacle 5 and the side faces 8 and 9 of the guide rail 2 in the region of the elevations 10 and recesses 12, as shown in FIG. 1 is displayed. This is deformed to the shape shown when pressing an initially flat shape and therefore forms a positive connection between the parts 2 and 3.
    These ratios are again in detail in FIG. 2 illustrated. A defined end position is provided during joining, since after joining the parts 2 and 3 the bearing surface 15 of the guide rail 2 lies on the bottom surface 14 of the receiving part 5.
    In FIG. 3 a variant of the invention is shown. This differs from the embodiment of FIG. 1 resp. FIG. 2 only in the fact that only a single fixing body 13 in the form of a strip of sheet steel is provided, namely in the left-hand part of the receiving part 5. In the other, i.e. right-hand part of the receiving part 5, the side face 9 of the guide rail 2 after the joining process against the side face 7 of the receiving part 5.
    The remaining gap width between the side surface 6 of the receiving part 5 and the side surface 8 of the guide rail 2, and accordingly the thickness of the strip of sheet steel 13, are chosen such that on the one hand a trouble-free joining of the parts is possible, but on the other hand after the assembly process, a sufficient clamping effect through the strip of sheet steel 13 is also present. The same applies with regard to the arcuate design of the elevation 10 of the receiving part 5. The analogous case naturally also applies to the exemplary embodiment according to FIG. 1.
    In FIG. 4 shows another embodiment of the invention in that both the side face 8 and 9 of the guide rail 2 are provided with a recess, but now also the side face 6 and 7 of the receiving part 5 have a recess 11. The recesses 11 and 12 substantially complement each other in the section shown to a circular shape, into which a fixing body 13 in the form of a pin with a likewise circular section can be inserted. Accordingly, the two parts 2 and 3 can first be joined together to subsequently slide in the pins 13 from the front side and in the longitudinal direction L, in order to establish the said positive connection.
    A variant analogous to FIG. 3, wherein the pin solution is only realized on one side 6 of the receiving part 5. In this case, the opposite side 7 of the receiving part 5 cannot have any recesses 11 and 7 respectively. 12.
    In FIG. 1, a solution is therefore outlined which works with two fixing bodies 13 in the form of insert plates. The two fixation bodies 13 are - as mentioned - simultaneously introduced with the guide rail 2 from above into the receiving part 5 when assembled, so that after placing the bearing surface 15 on the bottom surface 14 and after corresponding deformation of the fixation body 13 a positive connection between the guide rail 2 and the support element 3 have been established.
    With the solution according to FIG. 3, only a single fixation body 13 in the form of an insert plate is inserted or inserted when the parts 2 and 3 are joined together. brought in.
    The solutions according to FIG. 1 and FIG. 3 are particularly suitable if the connection of a longer guide rail 2 to a correspondingly long support element is to take place.
    With the solution according to FIG. 4, it is provided that the guide rail 2 is form-fittingly connected to the supporting element by means of two straight pins 13 which are inserted simultaneously on the front side. This solution can be used in the manner of FIG. 3 can also be varied accordingly, so that only a single pin 13 is used. These solutions are particularly suitable if only short guide rails 2 are to be connected to the support element 3.
