Abstract

The invention relates to a device and a method of mounting an antenna, in particular a roof antenna (1), on a vehicle body (12) with a base plate (2) connected to the roof antenna (1) outside the vehicle body and with a support element inside the vehicle body that is threaded into the base plate (2), the support element being formed as a bayonet plate (6), that a threaded connection (screw 3) has a pressure spring (compression spring 5) that produces a force between the base plate (2) and the bayonet plate (6), that between the base plate (2) and bayonet plate (6) there are guide elements (bolts 8, slots 9) that permit a limited shifting of the base plate (2) relative to the bayonet plate, that the bayonet plate (6) has limiting elements (bumps 10) that fit with the hole in the vehicle body (triangular hole 11) and that between the base plate (2) and the bayonet plate (6) there are projections (13) with complementary seats (14) in the second part that in an offset position of the base plate (2) relative to the bayonet plate (6) space the base plate (2) from the bayonet plate (6) and in another position engage in the seats (14).

Claims

1. An antenna (1), in particular a roof antenna, of a vehicle with a mounting element for securing the antenna (1) to a vehicle part (17a), the antenna (1) having a base plate (2) that carries a mounting element that fits through a hole in a vehicle part (17a), characterized in that during mounting or after mounting a sliding movement effects a gripping of the vehicle part (17a) without the use of a tool and furthermore that it is so constructed that the antenna (1) after mounting is in the desired end position, cannot move, and is sealed to the vehicle part (17a).

2. The antenna (1) according to claim 1, characterized in that a lower face of the base plate (2) carries a bayonet plate (9) that can be passed in a predetermined direction through a complementary hole in the vehicle part (17a) on mounting of the antenna (1) and that moves underneath the vehicle part (17a) to spatially overlap it such that movement of the bayonet plate (9) out of the hole of the vehicle part (17a) in a direction perpendicular to the upper face of the vehicle part (17a) is no longer possible.

3. The antenna (1) according to on claim 1, characterized in that on continuing to move in the predetermined mounting direction beyond fitting of the antenna (1) in the desired end position on the vehicle body (17a) there is an automatic gripping of the vehicle part (17) and a compression of a seal between the antenna (1) and the vehicle part (17a).

4. The antenna (1) according to claim 1, characterized in that a spring element is provided that produces the necessary gripping force by a prestressed spring element.

5. The antenna (1) according to claim 4, characterized in that the spring element is a spiral spring, a spring washer, or a stack of spring washers.

6. The antenna (1) according to claim 4, characterized in that the spring element and the bayonet plate (9) form a single unit.

7. The antenna (1) according to claim 1, characterized in that assembly is effected by the following steps:

transverse fitting of the support element, in particular the bayonet plate (9), through the opening in the vehicle part (17a) and subsequent engagement under the vehicle part (17) by means of pivoting movement.

8. The antenna (1) according to claim 1, characterized in that the support element is formed as a bayonet plate (6), that a threaded connection (screw 3) has a pressure spring (compression spring 5) that produces a force between the base plate (2) and the bayonet plate (6), that between the base plate (2) and bayonet plate (6) there are guide elements (bolts 8, slots 9, spacer sleeve 4, sleeve slot 7) that permit a limited shifting of the base plate (2) relative to the bayonet plate, that the bayonet plate (6) has limiting elements (bumps 10) that fit with the hole in the vehicle body (triangular hole 11) and that between the base plate (2) and the bayonet plate (6) there are projections (13) with complementary seats (14) in the second part that in one position of the base plate (2) relative to the bayonet plate (6) space the base plate (2) from the bayonet plate (6) and in another position engage in the seats (14).

9. The antenna (1) according to claim 8, characterized in that the guide is slots (9) in the base plate (2) or preferably in the bayonet plate (6) that interfit with bolts (8) that are fixed on the bayonet plate (6) or preferably on the base plate (2).

10. The antenna (1) according to claim 8, characterized in that the limiting elements are bumps (10) on the bayonet plate (6) that project toward the base plate (2).

11. The antenna (1) according to claim 1, characterized in that the hole in the vehicle body is generally triangular (triangular hole 11) and that the limiting elements (bumps 10) are arrayed on a triangle.

12. The antenna (1) according to claim 10, characterized in that the bumps (10) of the limiting elements are formed as projections (13).

13. The antenna (1) according to claim 1, characterized in that the bayonet plate (6) is generally triangular and has a portion (15) on one edge bent away from the base plate (2).

14. The antenna (1) according to claim 1, characterized in that the screw connection is a screw (3) that is threaded into the base plate (2) and that is surrounded by a compression spring (5) and that the bayonet plate (6) has a sleeve slot (7) that is elongated parallel to the slots (9) for the guide elements.

15. The antenna (1) according to claim 14, characterized in that between the base plate (2) and a head of the screw or a washer thereon there is a spacer sleeve (4).

16. A method of mounting an antenna (1) according claim 1 on a vehicle body, characterized in that the bayonet plate (6) is mounted on the base plate (2) such that the limiting elements (bumps 10, spacers 13, seats 14) produce a space with the base plate (2), that the bayonet plate (6) is fitted first with the bent-down portion (15) and then fully through the triangular hole (11) in the vehicle body (12) and is them shifted longitudinally (1) such that the limiting elements (bumps 10, spacers 13, seats 14) align over the triangular hole (11) and that then the base plate (2) is shifted so far along the slots (2) and the slot (7) that the spacers (13) engage in the seats (14) and the bumps (10) in the seats (14).

17. A tool for uninstalling the antenna (1) according to claim 1 from a vehicle body, characterized by a base body (19) with two fork-like bars (18) whose thickness generally corresponds to a height of the spacers (13) and with at least one handle (20), the bars (18) having flattened outer ends.

18. A method of uninstalling an antenna according to claim 17 from a vehicle body, characterized in that the tool (17) with the bars (18) is slid between the vehicle body (12) and the base plate (2) until the spacer elements (13) and/or the bumps (10) are lifted out of the seats (14), that the base plate (2) is shifted relative to the bayonet plate (6) so far that the spacer elements (13) and/or the bumps (10) bear on the bayonet plate (6) and that the roof antenna (1) with the base plate (2) and bayonet plate (6) are pulled out of the triangular hole (11).
