    专利说明:

    The invention relates to a flat profile connector system for collinear, end-to-end, elongated profile bodies, the profile bodies having an assembly side and a component receiving space, as well as an essentially U-shaped cross section and the section located between the U-legs forming the assembly side and this delimits towards the component receiving space, furthermore have web-like extensions of the U-legs facing the assembly side, running in the longitudinal direction of the respective profile body, wherein a connector rail can be inserted into the grooves, which overlaps at least two of the profile bodies at their respective end faces, according to the preamble of claim 1 .
    From DE 10 2019 111 626 A1, a profile connector for connecting a first profile to a second profile, with an elongated body that can be axially inserted and / or laterally rotated into an undercut first groove of the first profile and which has a T-shaped in an end face area is known Has head which can be inserted and / or screwed into an undercut second groove of the second profile and engages behind the second groove in the inserted state. In addition, a section element is provided, with the elongated body and the section element being pretensioned against each other exclusively by means of at least one fixing screw within the first groove in order to fix the profile connector to the first profile.
    By means of this solution, the forces acting on the profile and required to fix the profile connector can be distributed in a simple manner over a relatively large area within the profile groove.
    In order to produce the desired connection, however, the fixing screw has to be actuated with the aid of a tool, which entails additional expenditure both in terms of production and handling.
    The profile connector for connecting a first profile rail to a second profile rail for providing a ceiling substructure in dry construction according to DE 20 2007 008 901 U1 has a fastening device for attaching the profile connector to a side area of the first profile rail
    and a receiving device for receiving a front end section of the second profile rail. The receiving device is designed such that a front end section of the second profile rail in the case of a profile connector that is attached to the side area of the first profile rail can be received into the receiving device by means of an insertion movement, one direction of the insertion movement being essentially
    runs parallel to a longitudinal axis of the first profile rail.
    In one embodiment, the receiving device is designed such that the end section of the second profile rail is held in the receiving device without play. In this regard, there is a fixation in three, but at least in two
    perpendicular directions are necessary.
    The known profile connector is designed as a one-piece bent sheet metal part, with locking elements in the form of bending tabs being provided. The receiving device has an essentially U-shaped cross section with a base section and two side sections which run essentially perpendicular to the base section. The side sections have a clearance that essentially corresponds to a profile height of the end section of the corresponding profile rails.
    An aluminum profile rail system for LED strips is previously known from the generic DE 20 2011 104 306 U1. The profile rail system comprises, as a main component, a profile rail designed as an endless profile with a rear mounting side and a front lighting side. The rear mounting side of the profile rail is fixed to a fastening side, for example a wall or ceiling surface. When viewed in cross section, the profile rail has a horizontally running base plate and two opposite vertical outer side walls, so that a U-shaped space is formed. The base plate serves as a mounting surface for the LED strip.
    Furthermore, the profile rail comprises a T-slot on its rear mounting side, which is used to accommodate both a T-connector rail and a first
    Fastening element for suspension from the ceiling is designed with a T-foot.
    With the help of the T-connector rail, several profile rails can be connected to one another so that very long LED lights can also be designed. The T-connector rail is also designed as an endless profile and is preferably sold by the meter in defined system lengths like the profile rail
    provided.
    In the assembled state, especially in the case of systems suspended from the ceiling, the T-connector rail extends over the greatest possible length, which results in a high level of stability and a high degree of connection rigidity of the system
    shall be.
    It has been shown, however, that even if such a previously known connector rail corresponds virtually to the entire length of the profiles to be connected, sufficient stability is not guaranteed. In particular, mechanical shocks can lead to vibrations that make themselves noticeable as unpleasant noises. Furthermore, the mass of the overall system increases if connector rails of a corresponding length have to be used. In addition, the formation of the T-slot with a correspondingly complementary rail requires additional installation space, in particular on the height side, which runs counter to the goal of a filigree design of the overall system.
    From the above, it is therefore the object of the invention to provide a further developed, in particular flat profile connector system for collinear, elongated profile bodies which can be lined up collinearly at the end, which on the one hand enables assembly and disassembly as tool-free as possible and on the other hand avoids an undesirable increase in mass. In this regard, the system to be created should use a connector rail that can be handled intuitively and that is inexpensive to manufacture
    can be.
    The flat profile connector system according to the invention makes use of elongated profile bodies which can be collinearly lined up on the end face. Such profile bodies are known for the use and construction of so-called light strips, for example.
    The profile bodies have a mounting side and a
    Component receiving space.
    In the state of use, the assembly side is usually the top of the profile body. In the case of wall mounting, this mounting side points to the relevant wall and, in the case of ceiling mounting, to the ceiling or to one there
    existing substructure.
    The component receiving space is created in the case of a profile body having a substantially U-shaped cross section between the spaced-apart U-legs and the connecting section.
    Means for wiring and for receiving lighting components, in particular light-emitting diodes, can be present in the component receiving space.
    The use of the profile body in connection with the presented system is not limited to lighting applications. In this way, other supply lines or other components to be protected from external influences can also be accommodated or received in the profile body
    be.
    The aforementioned, located between the U-legs section forms the
    Assembly side and thus separates it from the component receiving area.
    A connector rail can be pushed into the grooves, which rail engages over at least two of the profile bodies at their respective end faces and extends over a section of the longitudinal extent of the respective profile body. According to the invention, the connector rail used now has a hat-shaped one
    Cross-section with recess section and two side legs.
    The side legs are so complementary to the grooves in the profile body that at least in sections the side legs of the
    Grooves are added in the profile body.
    In addition, an elongated clamping part is inserted in the recess section of the connector rail, which has a groove-shaped cross section,
    which has two longitudinally opposite clamping arms.
    A clamping lever is assigned to each of the clamping arms, the respective clamping lever having an actuating section penetrating the connector rail
    and a pressing section directed towards the respective clamping arm.
    The design is such that when a force is exerted on the actuating section, the pressing section moves in the direction of the clamping arm, the respective clamping arm then moving in the direction of the surface of the mounting side and coming into contact with it, so that a frictional connection is created.
    In this way, the connector rail is clamped between the grooves in the profile body and the surface of the assembly side, with the result that the corresponding profile bodies are positioned exactly against one another and form a fixed assembly unit.
    Clamping lever connection is excluded.
    In this regard, the pressing section has, on its section that comes into contact with the surface of the clamping arm, a toothing which, as it were, has a
    Claw and thus an additional form fit.
    In one embodiment of the invention, the clamping arms themselves can also have claw-like bends which point in the direction of the assembly side
    are oriented.
    The connector rail with clamping part is inserted into the grooves of the profile body on the front side and the clamping arms are in a force-free state during the insertion process. In this state, the actuating sections of the clamping levers face away from the assembly side. In the connected state, the clamping levers are folded over in such a way that the actuating sections rest on the surface of the connector rail. By turning over the clamping levers, which can themselves be designed as flat stamped and bent parts, an extremely flat connector rail results in the assembled state, which does not protrude or only protrudes by a very small amount over the web-like extensions of the U-legs.
    So it is the height extension of the connector rail with folded clamping levers equal to or smaller than the dimension of the web-like extension of the U-legs of the profile body.
    The connector rail has two slot-shaped openings, which are arranged in the recess section and run in the transverse direction, into each of which a
    Clamping part can be introduced.
    The connector rail, the clamping part and the clamping arms can be more preferred
    Way as inexpensive stamped and bent parts.
    On the opposite end faces of the connector rail there are bendable tongues for fastening the overall arrangement, for example to one
    A ceiling substructure is provided.
    In the component receiving space, lighting means, electrical wiring, light-scattering or light-bundling means can be arranged and there is the possibility of designing a light band using a plurality of profile bodies equipped in this way and connected according to the invention.
    The invention is intended below using an exemplary embodiment as well as
    are explained in more detail with the aid of figures.
    Here show:
    1 shows a representation of the individual parts of the connector rail with a hat-shaped cross section, recess section and elongated clamping part with clamping arms and clamping levers, specifically in a view of the underside of the connector rail;
    2 shows a representation of a connector rail provided for use in a plan view, the clamping lever recognizable on the right-hand side of the picture being in a folded position and the clamping lever shown on the left-hand side in the picture being such
    Has assumed the position that the arrangement of the connector rail with the clamping part accommodated is free of force and ready for insertion into corresponding grooves of a profile body (see FIGS. 3 to 7);
    Fig. 3-7 a sequence of handling the use of the connector rail for connecting two exemplarily illustrated profile bodies with a U-shaped cross-section, these web-like extensions of the U-legs have grooves that run in the longitudinal direction of the respective profile body, the grooves in the Connector rail can be inserted;
    8 shows a cross-section through the profile body with the connector rail, which is in the clamping position, with the clamping lever resting with its pressing section on the clamping arm, the clamping arm being in frictional connection with the surface of the mounting side of the profile body and the lateral legs of the connector rail being in a frictional connection position are located within the grooves in the profile body and
    9 shows a longitudinal section through the profile body with inserted connector rail and the details Z in the force-free state and Y in the clamping or frictional connection state.
    As can be seen, the connector rail 10 shown in FIGS. 1 and 2 has a hat-shaped cross section and has a recess section 11 with two lateral legs 12.
    Furthermore, an elongated clamping part 13 can be inserted in the recess section 11, which has two clamping arms 14 opposite one another in the longitudinal direction
    owns.
    A clamping lever 15 is assigned to each of the clamping arms 14, each of the clamping levers 15 comprising an actuating section 16 penetrating the connector rail 10 and a pressing section 17 directed towards the respective clamping arm 14.
    The actuating section 16 and the pressing section 17 enclose an angle by a small amount greater than 90 °, the length of the actuating section 16 being apparently many times greater than the length of the pressing section 17 in order to achieve the desired leverage.
    The pressing section 17 points at its with the surface of the clamping arm 14
    A toothing 18 comes into contact with the section.
    The clamping arms 14 can also have claw-like bends 19 which are oriented in the direction of the assembly side (see FIGS. 3 to 7).
    The ready-to-use state of the connector rail 10 is shown in FIG. 2, specifically with the actuating section 16 of the clamping lever 15 shown on the left in the picture erect.
    The clamping lever shown on the right in the picture has a position with the actuating section 16 folded over, as is the result of the connection process according to FIG.
    The elongated clamping part 13 has an area 20 connecting the clamping arms 14, with which the actuation in the recessed section of the connector rail 10 by the bent lugs 21, which engage in recesses 22 in the area 20, is possible. In addition, a notch 23 can be provided which dips into a complementary further recess 24.
    The connector rail 10, the clamping part 13 and the clamping lever 15 can be used as
    metallic stamped and bent parts are carried out.
    On the opposite end faces of the connector rail 10 can
    Bendable tongues 25 for attachment to a substructure (not
    shown). The direction of bending is symbolized in FIG. 2 with an arrow representation.
    With the help of Figures 3 to 7, the assembly sequence using the flat profile connector system will be explained in more detail.
    A related profile body 1 has an assembly side 2 and a component receiving space 3 and has an essentially U-shaped cross section. The section located between the U-legs forms the aforementioned assembly side 2 and borders this side towards
    Component receiving space 3.
    Furthermore, there are web-like extensions 4 of the U-legs pointing towards the assembly side. These web-like extensions 4 have in
    Grooves 5 running in the longitudinal direction of the respective profile body 1.
    The grooves are designed in such a way that they can accommodate at least sections of the lateral legs 12 of the connector rail 10. The connector rail 10 can therefore be pushed into the grooves 5, as can be seen from the combination of FIGS. 3 and 4.
    After the connector rail 10 has reached its desired position in the area of the section of the profile body 1 to be connected, the clamping lever 15 is moved in the direction of the corresponding clamping arm 14 with the aid of the actuating section 16. As a result, the pressing section 17 comes into contact with the top of the corresponding clamping arm 14. The clamping arm 14 with its respective claw-like bends 19 then comes into contact with the surface of the mounting side 2, so that the necessary frictional connection is established.
    Then, as shown in FIGS. 5 to 7, a further profile body 1 'is moved over the connector rail 10 in the direction of the profile body 1 using the grooves present there until a collinear end-face position according to FIG. 6 is obtained. Then, analogously to the production of the necessary frictional connection, the second of the clamping levers is also turned over in such a way that with
    Exercising a corresponding force on the actuating section 16 is the
    Pressing section 17 is moved in the direction of the clamping arm 14 and this is in contact with the surface of the mounting side 2 to form the frictional connection
    got.
    In particular from the representations according to FIGS. 3 to 7, but also with regard to the cross-sectional representation according to FIG
    Profile connector system results, which can be assembled completely tool-free, but also
    can be dismantled.
    The cross-sectional view through a profile body with a frictional connection rail 10 shows that in the frictional connection state the claw-like bends 19 of the relevant clamping arm 14 rest on the surface of the mounting side 2, while at the same time the pressing section 17 on the top of the corresponding clamping arm 14 under frictional connection and rests by clamping, the actuating section 16 of the corresponding clamping lever having a horizontal position and coming into contact with the
    Connector rail 10 occupies.
    This process of clamping or releasing the non-positive connection using the flat profile connector system can also be understood with the aid of the representations according to FIG. 9 with the details Z and Y.
    In the state of the detail Z, the relevant clamping lever 15 is in a tension or force-free state. The claw-like bends 19 are located at a distance from the surface of the mounting side of the
    Profile body 1 or 1 '.
    According to the illustration Y, the clamping lever 15 shown on the right-hand side in the figure is folded over in the direction of the surface of the connector 10. In this quasi over dead center position, a clamping force is exerted on the corresponding clamping arm 14. The claw-like bends 19 get into intimate here
    Contact with the surface of the assembly side 2 with the formation of the necessary frictional connection.
    When the connector rail 10 is inserted into the grooves 5 of the profile body 1 or 1 ', the clamping arms 14 are therefore free of force and the actuating sections 16 of the clamping levers 15 point away from the assembly side 2. In the connected state, the clamping levers 15 are folded over in such a way that the actuating sections 16 are positioned on or off the surface of the connector rail 10.
    rest.
    The connector rail 10 has two slot-shaped recesses 26 formed in the recess portion 11, in each of which one of the clamping levers 15
    can be brought in. In the component receiving space 3, for example, lighting means, electrical wiring and light-scattering or light-bundling means
    to be ordered. A large number of connected profile bodies equipped in this way
    1; 1'can be joined to form a light strip.
