  • the fastening element can, for example, exert a force on components of the groove arrangement, as a result of which the fastening element is braced or jammed in the groove arrangement.
  • the fastening element when the side cap is in its covering position, the fastening element interacts with the groove arrangement in such a way that an unintentional or accidental removal of the side cap from the covering position is prevented.
  • the covering of the front opening of the housing can be ensured in this way.

  • the housing according to the invention by arranging and fixing the side cap directly on the hood, elements that protrude from the closer body for such an arrangement and fixing of the side cap can be dispensed with. Demands on the size of the installation space required for the door drive can thus be reduced.
  • the housing according to the invention can preferably be characterized in that the fastening element has a base body aligned in the insertion direction and a fixing device arranged on the base body, the base body having two longitudinal sides which are at least partially spaced perpendicular to the insertion direction in a maximum width, so that the base body when inserted each longitudinal side engages in one of the groove receptacles, and wherein the fixing device can be brought from an initial position into a fixing position during and/or after being pushed in, in which the at least one fixing device fixes the side cap in its covering position in the groove arrangement in a non-positive and/or positive manner .
  • the fastening element essentially has two sections, namely a base body and a fixing device. As explained below, these two sections are designed to fulfill different tasks.
  • the base body extends transversely to the direction of insertion, which ensures that the base body engages in both groove receptacles of the groove arrangement of the hood.
  • the two longitudinal sides of the base body which are at least partially spaced apart in the maximum width, are thus arranged in one of the groove receptacles, in particular arranged in a contacting manner, during and after the insertion of the fastening element into the groove arrangement.

  • the starting position is that position which the fixing device assumes before the fastening element is pushed into the groove arrangement.
  • the fixing device can now be brought into a fixing position that differs from the initial position.
  • This movement of the fixing device from the starting position into the fixing position can be made possible in particular by an elastic configuration of the fixing device itself or by an elastic arrangement of the fixing device on the base body.
  • the fixing position of the fixing device is selected in such a way that a non-positive and/or positive fixing of the side cap in the groove arrangement is thereby produced.
  • the division of the fastening element into at least one base body and one fixing device can make it possible for the fastening element to be guided in the groove arrangement on the one hand and for the non-positive and/or form-fitting fixing to be generated by different sections of the fastening element on the other.
  • a need-based adaptation of the base body and the fixing device to the respective application can be made possible in a particularly simple manner.
  • the base body has an, in particular peripheral, frame element for guiding the fastening element in the groove arrangement, the frame element forming the longitudinal sides at least in sections. It can preferably be provided that the frame element of the base body surrounds the entire fastening element. Stability of the fastening element, for example against twisting, can be increased as a result.
  • the housing according to the invention can include that the fixing device comprises at least one tensioning element, wherein the at least one tensioning element has a fixed end, with which the tensioning element is arranged on the base body, and can be elastically deflected from a basic position, the at least one tensioning element also being in the Fixing position of the fixing device is deflected into a deflection position different from the basic position and the fastening element is fixed in a non-positive manner in the groove arrangement.
  • the deflection of the clamping element Due to the deflection of the clamping element from a basic position to the deflected position, a force is generated, mostly due to the elasticity of the clamping element and the connection of the clamping element at its fixed end to the base body, which acts on the clamping element in the direction of its basic position.
  • This force makes it possible to fix the fastening element in the groove arrangement in a non-positive manner.
  • the deflection of the clamping element can preferably be caused by parts of the groove arrangement.
  • the fixing device has a clamping element of a first type, which extends transversely to the direction of insertion and has a free end opposite the fixed end, which extends transversely to the direction of insertion in the direction of one of the groove arms via one of the longitudinal sides of the Base body protrudes, whereby the clamping element of the first type can be deflected against the direction of insertion into the deflected position during insertion by resting the free end on one of the two groove arms and the fastening element can thus be fixed in the groove arrangement with a force fit, in particular can be fixed in a self-locking manner.
  • tensioning element of the first type describes a specific configuration of a tensioning element according to a first type, in other words a first possible configuration of a tensioning element within the meaning of the invention.
  • other tensioning elements are also described as part of the invention, which are designed according to further possible configurations, ie, for example, according to a second type, according to a third type, etc.
  • the designation "clamping element of the ... type” can thus be used to distinguish between the various configurations of the clamping elements used within the meaning of the invention.
  • the different types of clamping elements can be used individually and, as far as technically sensible and possible, also in any combination.
  • the clamping element of the first type which protrudes with its free end beyond the corresponding longitudinal side of the base body, contacts this free end when the fastening element is inserted in one of the two groove arms of the groove arrangement. Since the opposite fixed end is arranged on the base body, the free end is automatically deflected counter to the direction of insertion.
  • the clamping element of the first type also remains in the covering position this deflected position, in which the free end is deflected counter to the direction of insertion from the basic position. A movement of the fastening element and thus the side cap against the direction of insertion requires an opposite movement of the free end of the clamping element of the first type, which is however prevented by its length.
  • This length can preferably be selected in such a way that a deflection angle ⁇ of the clamping element of the first type, which describes the deflection of the clamping element from its basic position into its deflected position, adjusts itself in such a way that together with a sticking number ⁇ H of the corresponding slot arm, it generates a self-locking ( ⁇ tan -1 ⁇ H ).
  • a non-positive fixing of the side cap in the covering position can be made possible in this way in a particularly simple and reliable manner, since high holding forces can be generated in particular with low tensions of the tensioning element of the first type. A loss of fixation due to signs of fatigue in the material of the clamping element of the first type can be avoided in this way.
  • the housing according to the invention can be further developed in such a way that the free end has a rounded contact section for contact with the slot arm.
  • Rounded off within the meaning of the invention includes, for example, a configuration of the outer contour of the free end as a convex polygon, as an arc of an ellipse or as an arc of a circle up to a semicircular configuration. Combinations of different configurations of this type are also possible.
  • a rounded contact section can enable the free end to rest securely on the groove arm, regardless of the existing deflection of the clamping element of the first type. A loss of the self-locking fixation, caused by the free end resting uncertainly on the groove arm, can be avoided in this way, or at least the risk of such a loss can be reduced.
  • the free end has an insertion aid slanted to the insertion direction for inserting the fastening element into the groove arrangement, with the insertion aid in particular being arranged adjacent to the contact section in the insertion direction.
  • the fastening element with the clamping element of the first type is pushed into the groove arrangement along the direction of insertion. Since the free end of the clamping element of the first type protrudes beyond the longitudinal side of the base body of the fastening element, a canting of the free end, in particular of the contact section, on the corresponding slot arm cannot be ruled out.
  • a slanted insertion aid which can be arranged directly in front of the contact section in the insertion direction, allows the clamping element of the first type to begin deflecting from its basic position in the direction of its deflected position in a particularly reliable manner. A canting as described above can thus be prevented.
  • the housing according to the invention can preferably also be designed in such a way that the clamping element of the first type extends transversely to the insertion direction over at least half, preferably at least three quarters, of the maximum width of the base body.
  • An extension over half, better still over three quarters, of the maximum width of the base body has proven to be particularly advantageous, since on the one hand the deflection angle ⁇ is already significantly reduced, but at the same time a secure arrangement of the fixed end of the clamping element of the first type on the base body is ensured can.
  • the housing according to the invention can be characterized in such a way that the fixing device has two clamping elements of a second type which are arranged on the longitudinal sides of the base body, in particular on the frame element, and which can be brought out of the basic position into the deflected position during insertion by resting against one of the grooved arms.

  • the end of the respective clamping element of the second type that is opposite the fixed end can be designed as a fixed end that is also arranged on the base body or as a movable free end that is not connected to the base body. Since the clamping elements of the second type are arranged elastically on the base body, the above-described non-positive fixation of the fastening element in the groove arrangement results, which is maintained even when the side cap reaches the covering position.
  • the fixing device has another clamping element of a third type, which extends counter to the direction of insertion and is arranged, in particular centrally, between the longitudinal sides of the base body, with a fixed end of the clamping element during insertion the third type opposite free end of the clamping element of the third type can be brought from the basic position into the deflected position by resting against the surface element of the groove arrangement.
  • the clamping elements of the second type are deflected by the groove arms transversely to the direction of insertion.
  • the clamping elements of the second type can peel off the clamping elements of the second type, as a result of which the non-positive fixing of the fastening element in the groove arrangement can be reduced by the clamping elements of the second type.
  • An additional clamping element of the third type can generate an additional clamping force which, in contrast to the clamping elements of the second type, acts on the surface element of the groove arrangement. High clamping or clamping forces can be provided in this way, so that a secure non-positive fixation of the fastener can be ensured in the groove arrangement.
  • the secure non-positive fixation can preferably also be made possible solely by the clamping element of the third type.
  • the free end of the clamping element of the third type has an insertion aid slanted to the direction of insertion and/or an actuating section for manual actuation to facilitate insertion of the actuating element into the groove arrangement.
  • the clamping element of the third type can exert the clamping force described above on the surface element
  • the clamping element of the third type is designed in such a way that in the basic position of the clamping element the free end of the clamping element abuts the front end of the surface element when it is pushed in. It is therefore not possible to slide the entire fastening element into the groove arrangement with the clamping element of the third type in its basic position.
  • a beveled insertion aid makes it possible for the clamping element of the third type to be automatically deflected in the direction of the deflected position when it reaches its free end at the front end of the planar element.
