Definitions

  • the present invention relates to a holder for vehicles, in particular an antenna holder, with a carrier on which a fastening element in the form of a suction foot and a receiving element for a unit to be fastened are arranged, the carrier having at least one leg on which the suction foot is attached, the squeegee having a suction plate and an actuating element displacing the suction plate via a bolt part with at least two opposing grip surfaces.
  • Such a holder is known from DE-Gbm 89 12 704.8.
  • This antenna holder is used to attach an antenna, for example an antenna for car telephones. It has an approximately U-shaped part with two strip-shaped legs, one leg having at its free end an angled fastening section with a receiving opening for the antenna.
  • An antenna holder of this type is clamped with the U-shaped part between the upper edge of a window of a vehicle and the door frame when the window is closed. The antenna cable is led into the vehicle interior from the outside of the window via a groove pressed into the strip-shaped legs.
  • the antenna holder described above has proven itself well in use. However, the antenna holder must be held securely when the vehicle window is closed.
  • a generic antenna holder which is commercially available, also has a U-shaped bracket, on the outside of which the antenna is attached and on the inside of which a suction cup with a suction plate is arranged, the suction plate being connected to a bolt part by means of a pivotable lever can be sucked into the pane or detached from the pane. It has been shown that this squeegee can only be sucked onto the pane with the aid of both hands. The squeegee must be pressed against the disc with one hand and the lever must be pivoted into the locking position with the other hand, so that a sufficiently large vacuum is created between the suction plate and the disc.
  • the displacement path of the bolt that can be achieved with the lever is not sufficient to form a sufficiently large curvature of the suction plate and thus a sufficiently large vacuum between the disc and the suction plate.
  • the purpose of the squeegee is missed because it can be released with little effort, but on the other hand it should hold the antenna holder securely on the vehicle window, even when the window is open.
  • the present invention has for its object to provide a holder for vehicles, in particular an antenna holder, which has a squeegee, which is easy and at the same time safe on a smooth only with the help of an operator's hand Surface, for example the window pane of a vehicle, can be attached.
  • the actuating element has an operating button which has conical surfaces as the gripping surface, the operating knob on the side facing the carrier having a larger diameter in the region of the gripping surfaces than on his the Side facing away from the carrier, and that the bolt part is displaceable via at least one guide part which is guided on a guide surface, the guide part being assigned locally to either the carrier or the control button and the guide surface being locally assigned to the other part of the carrier and control button and wherein the guide surface has an incline in the direction of the axis of rotation of the bolt part.
  • an operating button which is rotatable about the axis of the pin as the axis of rotation and which furthermore has inclined or conical grip surfaces
  • the pin can be rotated and on the other hand the user is forced due to the conical surfaces of the operating button to press it in the direction of the pane, since it inevitably slips away from it when the fingers are pressed together in the direction of the pane.
  • the control button for example on its underside, is guided on the carrier, namely along an inclined surface, which removes the control button and thus the bolt part and the suction plate attached to it from the disk, as a result of which the suction foot is sucked tight .
  • This provides extremely simple one-hand operation. To release the holder, simply turn the control button in the opposite direction.
  • the conical surfaces serving as gripping surfaces are preferably formed by a truncated cone surface surrounding the actuating element or the operating button.
  • Such a control button has the advantage that this control button, with the above-described operation of the inclined surfaces, can be gripped by the user in any position.
  • the grip surfaces should preferably form an angle between 20 ° and 60 ° with the axis of rotation of the bolt part, the optimal angle being between 30 ° and 40 °, namely 35 °. With this angle of inclination of the grip surfaces, a sufficiently large force component is exerted in the direction of the fastening surface or disc when gripping the grip surfaces between the thumb and the index and middle fingers.
  • the guide surface which guides the control knob when rotating about the axis of rotation and removes it from the fastening surface or moves it towards the fastening surface in the case of reverse rotation is preferably assigned to the carrier. It is sufficient that the control button has on its underside a guide part sliding on the guide surface, for example in the form of a web; However, a surface corresponding to the guide surface in its inclination can also be formed on the control button.
  • the guide surface with such a slope that the tangents of the guide surface form an angle between 5 ° and 15 ° with the plane perpendicular to the axis of rotation of the bolt part, preferably the axial displacement of the bolt per revolution of the Control button should be about 5 mm. In this dimension, it is usually sufficient to turn the control knob by approximately 180 ° in order to suck the squeegee onto the fastening surface.
  • a release device is advantageous for releasing the suction plate from the window, for example of a motor vehicle, in order to support the release of the suction plate or squeegee.
  • a release device in particular in connection with a U-shaped carrier, such a detachment of the squeegee from the pane is facilitated.
  • a bolt is guided in the bolt part. This bolt presses against the disc when released, so that it pushes the suction plate off the surface.
  • the bolt is held in its advanced position, projecting beyond the suction surface of the suction plate, under the pressure of a spring. This bolt is pressed into the bolt part against the pressure of the spring when the squeegee is fastened to the base; When the foot is released, the bolt is then pushed back over the surface of the suction plate and presses the suction plate off the surface.
  • This support when loosening the holder is particularly important for holders that have a carrier with a U-shaped bracket, so that these holders, attached to the edge of a window pane, cannot be removed laterally, but this may be necessary in order to To release the squeegee from the suction engagement with the disc.
  • this is formed by a valve device which has a valve part which can be moved from a closed position to an open position, air being supplied in the open position via an opening in the suction surface of the suction plate. With such an air supply, the negative pressure between the squeegee and the support or disc is compensated, so that the squeegee detaches from the disc.
  • the valve part is preferably formed by a bolt which is sealingly guided in the closed position. Such a seal can be made in a simple, constructive manner by means of an O-ring seal, which preferably bears around the bolt.
  • Such an O-ring device can, for example, be clamped between a flange of the bolt and a flange or annular projection in the channel in which the bolt is guided, so that it lies sealingly between the surface of the bolt and the wall of the guide bore of the bolt .
  • the pressure is then removed from the O-ring seal, so that air can flow between the bolt and the bore which receives the bolt to the suction plate or the opening formed therein in order to release the squeegee.
  • the bolt is preferably held in the closed position by a spring so that to release the seal the bolt must be moved against the pressure of the spring and the bolt immediately returns to its closed position to the holder for re-attachment to a smooth surface ready to provide.
  • the bolt is preferably arranged in the axis of rotation so that it detaches the squeegee evenly in all directions.
  • a structurally simple structure is provided if the spring is a helical spring that bears against a head part of the bolt under tension.
  • the bolt can be inserted into the bolt part via an opening in the control button, the spring and bolt being secured via an end cap inserted into the opening.
  • the antenna cable of an antenna attached to the carrier for example an antenna for operating a car telephone, is passed through the sealing gap between the window pane and window frame and runs from there to the car telephone.
  • a cable guide is provided on the support, below the control button, into which the antenna cable is inserted. It is usually sufficient to guide this cable guide over an angle section of 90 ° around the circumference of the control button, a large radius should be chosen so that the cable is not bent too much.
  • the cable guide is formed by individual holding elements, which are spaced apart from one another, between which, as required, the cable can be led out at different points.
  • hooks should preferably be selected as holding elements, the hook openings of which point inwards to the axis of rotation of the operating button, which enable simple clamping in and easy release from their engagement.
  • FIG. 1 shows an antenna holder 1 which has a carrier 2 with a U-shaped bracket 3, an operating element 4 and a receiving element 5.
  • This antenna holder 1 is a holder that is used for motor vehicles.
  • Such an antenna holder 1 is placed with its U-shaped bracket 3 on the window pane of a motor vehicle, not shown, in such a way that the web 6 of the U-shaped bracket 3 sits on the edge of the pane, one leg 7 of the carrier 2, which carries the receiving element 5 for an antenna, not shown, on the outside of the disc and the other leg 8, which carries the control element with the control button 9, rests on the inside of the disc.
  • a cable channel in the form of a bead 10 is formed, through which an antenna cable 11 is guided from the outside of the vehicle into the vehicle interior, invisibly and simultaneously protected.
  • the guidance of the cable 11 is indicated in FIG. 2 by the cable 11 shown with broken lines.
  • the operating element 4 on the carrier 2 is equipped with a suction foot 12 which has a suction plate 13 with the surface facing the attachment surface which can be sucked onto the base or a window pane .
  • the squeegee 12 is attached to the end of a bolt part 14.
  • the bolt part 14 is guided in a central bore 15, the axis of the bore coinciding with the axis of rotation 16 of the control button 9.
  • a bolt 17 is inserted, which protrudes through an opening of the suction plate 13 in front of the underside of the suction plate.
  • a helical spring 19 bears against a head part 18 of the bolt 17 and is secured in the central bore 15 by an end cap 20.
  • the end cap 20 is clamped with not shown locking parts in the control button 9.
  • the control button 9 has circumferential grip surfaces 21 which are inclined outwards and form a truncated cone surface.
  • the grip surfaces 21 are profiled with grooves, as can be seen in FIGS. 1 and 4.
  • the angle ⁇ , at which the grip surfaces 21 of the control button are inclined to the axis of rotation 16, is approximately 35 ° in the embodiment shown.
  • the operating element 4 is guided on the carrier 2 on a guide carrier 22, which has a guide surface 23 on its outward-pointing section, which has a slope in the direction of the axis of rotation 16.
  • a guide part 24 not shown in more detail, for example in the form of a web, is guided such that the control button 9 moves in the direction of the axis of rotation. With this displacement, the squeegee 12 is pushed forwards or backwards in the direction of the axis of rotation 16, depending on the direction of rotation of the control knob 9.
  • the antenna holder shown When attaching the antenna holder 1 to the window of a motor vehicle, the antenna holder shown is placed on the edge of the window and the control button 9 is grasped on its grip surfaces 21 with the thumb on one side and the index or middle finger on the opposite side , pressed in the direction of the vehicle window and turned clockwise.
  • the suction plate 13 of the squeegee 12 By pressing the suction plate 13 of the squeegee 12 is pressed flat against the window pane so that the air escapes, and with the subsequent rotation of the control knob 9 clockwise, the bolt part 14 and thus the squeegee 12 is pulled away from the pane, causing between the suction plate 13 and the disc creates a vacuum that ensures that the suction cup 12 is held securely on the disc.
  • the control knob 9 To release the antenna holder 1 from the disk, the control knob 9 is rotated counterclockwise, the bolt 17, which forms a release device, presses against the disk under the pressure of the coil spring 19, thereby supporting the lifting of the suction plate 13 from the support .
  • This assisted loosening is important because, as can be seen from FIG. 2, the U-shaped bracket 3 leaves no space between the pane and can be pulled off the pane inserted therein.
  • FIG. 5 shows a further embodiment of a release device in a holder, the basic structure of which is similar to the holder shown in FIGS. 1 to 4. For this reason, components that are the same or functionally the same as those of the previously described embodiments are denoted by the same reference numerals and are only described again insofar as are necessary to understand the structure of this embodiment.
  • the release device is formed by a valve arrangement which has a bolt 17 ′ which is guided in an insert part 27, which in turn is inserted in the bolt part 14.
  • the bolt 17 ' has a head part 18' at its inner end, an O-ring seal 28 being inserted between this head part 18 'and the lower end of the insert part 27.
  • the bolt 17 ' is held in a closed position of this valve arrangement by a helical spring 19' which bears against the underside of the head part 18 'and presses the bolt 17' outwards in such a way that an end cap 20 'is pressed outwards.
  • a cable guide 25 which consists of individual, hook-shaped holding elements 26, one of which is also shown in Figure 3.
  • the antenna cable 11 which is guided by the receiving element 5 through the bead 10 to the interior, is clamped and guided below or below the control button 9, so that it is covered by the control button 9 and the operation of the control button 9 when fastening and not hindered when loosening.
  • the receiving element 5 for an antenna can be pivoted about the axis 27, as can be seen in FIGS. 1 and 2.
