Antenna and method for mounting an antenna on a vehicle by a clamping force, preferably obtained by a translational displacement action

The invention relates to an antenna of a vehicle and a method for mounting the antenna on a vehicle component according to the features of the respective preamble of the independent claims.

Such, for example, designed as a roof antenna antenna is a conventional manner thereby fixed to a body that the base plate has a threaded neck which is inserted through an opening in the body, in which case from inside the base plate by means of a support member (integrally formed on the bottom plate threaded stud) is bolted to the body using a nut. In this assembly Two people are required to perform an installation, as a person, the roof antenna in its correct position postion must hold on to the vehicle part from the outside, while the other person performs the gland within the body with the aid of tools.

The known roof antennas and their assembling are much too expensive and time-consuming especially in connection with the present assembly requirements.

The invention is therefore based on the object to achieve a simplification of the assembly of the antenna, the mounting without tools, without a second person and no other aids should occur. Nevertheless, to be achieved in that the antenna is attached to a simple assembly so the correct position on the vehicle part, that the connection permanently backlash, sufficiently strong and waterproof. It should further be achieved an increased freedom in the design of the assembly procedure, since the antenna at any stage of the assembly procedure is to be mounted from outside the body here, even if a headliner is already mounted in an inner portion of the body.

This object is achieved by the features of claim 1.

According to the invention it is provided that the disposed on the bottom plate of the antenna support member is configured such that it applies during assembly or after assembly by means of a sliding movement of a force acting on the vehicle component clamping force without using a tool, and is further formed so that the antenna according to has been mounted in the correct position, clearance and sealingly fixed to the vehicle component.

The invention therefore uses the basic idea, known compounds such as threaded connections, snap connections, and the like to replace it by a clamping force which is applied to the vehicle component during and / or after mounting the antenna. It is thus possible that a single person can mount the antenna easier, without, for example, a mother has to be screwed onto a threaded spigot of a second person, while the first person holds the antenna in the correct position on the vehicle part. This reduces the number of parts and also the lack of a mounting tool is obtained in an advantageous manner. The most essential Vorteif is but that only one person can mount the antenna, in one step, in which namely done the bottom plate with the molded-on support member through an opening in the vehicle part and the antenna moves so, in particular shifted and twisted is that during movement or after movement, the clamping force is generated, wherein the support element is further configured such that the further execution of the movement is no longer possible when the antenna is in the correct position, clearance and sealingly fixed to the vehicle component. Preferably, at this moment the highest clamping force is achieved.

The clamping force is applied by a sliding movement, said longitudinal movement of the antenna, in particular the bottom plate takes place relative to the vehicle part. In this connection, the screwing a nut is not understood on the known threaded pin as a rotational movement. Nor should be understood within the concept of clamping force a bond.

In development of the invention a bayonet plate is attached to the underside of the bottom plate of the antenna, which is inserted through a predetermined sequence of movements of the attack on the antenna into this matching opening in the vehicle component therethrough and placed below the vehicle part into engagement or into spatial coverage so that a withdrawal of the bayonet plate from the opening in the vehicle part in the surface of the vehicle part the vertical direction is no longer possible. The configuration of the support element as a bayonet plate has the advantage that the arrangement of the antenna can be performed on the vehicle part by a simple predetermined sequence of movements. For this purpose, the vehicle component has an opening corresponding to the outer contour of the support element such that the implementation of the support element through the opening of the vehicle part is possible in a not correct position position of the antenna, but after reaching the correct position position of the antenna to the vehicle component withdrawal is prevented. Through the interplay of contour of the opening in the vehicle part and the outer contour of the support element or its bayonet plate it is therefore possible that the antenna initially carried out in a non-position right position through the opening in the vehicle part, displaced and in carrying out the sliding movement, the clamping force is generated that during and / or after execution of Schiebebbewegung fix the antenna to the vehicle part. This predetermined sequence of movements (for example, inserting the antenna from above into the opening and subsequent sliding movement) allows that a single person, the antenna can commit to the vehicle component in the desired manner.

In a further embodiment of the invention by continuing the predetermined movement sequence of the attack to the antenna upon reaching the intended position on or at the vehicle component automatically a clamping on the vehicle part, and a bias of a seal between the antenna and the vehicle component is triggered. Such a configuration has the advantage that the antenna can be inserted through the opening in the vehicle part and rotated until the correct position of the antenna has been reached to the vehicle part. Only when this correct position is reached, the clamping force (bias) is initiated automatically, which in turn causes the bottom plate is used with the interposition of a seal on the vehicle component. This has the advantage that the seal is not effective until the antenna is in the correct position aligned with the vehicle part to ensure a simple relative movement between the vehicle component and antenna. Only when the correct position of the antenna has been reached, the clamping force is released, which is also caused by the seal that the antenna not only sealing but also stable, especially under compensation of tolerances, is fixed to the vehicle component.

In development of the invention it is provided that the necessary clamping force is generated by a prestressed spring element. In this case, the spring element may be formed as a spiral spring, cup spring pack or the like. In of preferential embodiment, the spring element forms a unit with the bayonet plate of the support element.

As already described, is to further embodiment of the invention, the predetermined sequence of movements of the moving steps: oblique insertion of the support member through the opening in the vehicle part and subsequent sliding movement back and forth, whereby the support member is engaged with the application of the clamping force to the vehicle component.

Furthermore, it is provided that with respect to a device for fixing the antenna the Sttitzelement is designed as a bayonet plate, that the threaded connection has a tension spring which produces a clamping force between the bottom plate and the bayonet plate, that between the base plate and bayonet plate guide elements are provided which have a limited displacement allow the base plate and the bayonet plate against each other, that the bayonet plate comprises boundary elements that fit the opening in the body and that between the base plate and bayonet plate spacers are provided with corresponding recesses in the second component, which in a displacement position of the bottom plate to the bayonet plate a distance of the bottom plate make sure the bayonet plate and engage in the other displacement position in the recesses. This is a device that is brought to the installation location of the vehicle as a complete unit. The device forms a complete unit, so that the simplification of logistics through the elimination of the mother, the support member and the like at the installation arises. All necessary parts are captively assembled on the roof antenna.

In a further embodiment of the invention it is proposed that the guide elements are slotted openings in the base plate or, preferably, in the bayonet plate, which are provided with pins in operative connection, which are fixed to the bayonet plate or preferably to the bottom plate. This allows the base plate and the bayonet plate within the slot openings limited slide against each other, their importance will be described hereinafter.

The restraints are surveys, which are mounted on the bayonet plate, projecting toward the base plate and are at least partially disposed within the boundary of bayonet plate.

The opening in the body has a substantially triangular shape, wherein the limiting members or projections are adapted to the triangular shape. It concerns with the triangular shape, although to a greater opening in the body than the known opening. This, however, the introduction of cable with connectors and the like to the antenna, in particular roof antenna out simplified.

The elevations of the limiting elements can be simultaneously formed as spacers, so that a simplification, this results in that not separate spacers and separate delimiting elements must be provided. This restriction / spacer elements may further include yet the guide elements, thus resulting in an optimal simplicity.

The bayonet plate is also substantially triangular design and adapted to the size of the triangular opening in the body. At one side of the triangle, the bayonet plate on a protruding surface of the bottom plate angle which is narrower than the corresponding side length of the triangular opening.

The threaded connection comprises a screw which is screwed into the bottom plate. It can of course also be used a plug screw with a nut. a spacer sleeve can be provided between the base plate and the screw head or a washer arranged there, which is surrounded by a compression spring, whereby the clamping force between the bayonet plate and the base plate is produced. The bayonet plate here has a sleeve slot, which is formed in the direction suitable to the slit openings for the guide elements, so that the free mobility between bayonet plate and bottom plate is provided.

The assembly of the device according to any one of the preceding claims to a vehicle body is carried out according to the following method steps:

First, the bayonet plate is mounted on the bottom plate so that the limiting elements generate a distance from the bottom plate, that is, the limiting elements are based on the bayonet plate or inversely.

The car antenna is lifted by the bayonet plate first with the angular surface of the bayonet plate and then fully inserted into the triangular opening in the body and then as in the direction of the roof aerial that the limiting elements lie within the triangular aperture and the boundary of the bayonet plate, the opening in the body engages behind. The bayonet plate is thus in a triangular opening, at least in the direction in which the bottom plate is moved later determined. Then, the base plate or the roof antenna with the bottom plate is moved so far along the slit openings and the sleeve slot, namely with respect to the fixed bayonet plate until the spacers snap into the recesses. Then the full spring force can develop between bayonet plate and bottom plate and pull the bottom plate against the body so that the attached to the bottom plate gasket or sealing strips are printed on the body surface. At the bottom plate facing surface of the bayonet plate tips may be attached advantageously coming inside to the body to rest, penetrate the interior painting of the body and establish a ground contact.

Instead of tips, of course, a corresponding intermediate plate or pad may be provided on the bayonet plate, which produces the ground contact. After snapping the spacers in the recesses a stable definition of the bottom plate or the roof antenna is opposite the bayonet plate ensured. The bayonet plate in turn is determined by the limiting elements in the roof opening, thus leading to an accurate, permanent fixing of the roof antenna is placed on the body. The definition and assembly takes place, as is apparent from the steps, without tools and without tools and only by a person or a technician.

To disassemble the device without destruction, a tool is proposed which aufinreist a body having two forked arranged strips, the thickness of which essentially corresponds to the height of the spacers. The body further includes at least one handle, preferably two handles, so that safe handling can be done.

For dismounting the tool is moved with the slats between the bodywork and the floor plate to the spacing elements are raised from the recesses. Then, the bottom plate relative to the bayonet plate may be pushed back so far that the spacing elements are supported on the bayonet plate and at the level of the bayonet plate. Thereby, the distance between the base plate and bayonet plate is emeut prepared. The roof antenna is then removed or tipped out so that only needs to be more, the electrical connection to the antenna resolved with the bayonet plate from the triangular opening. Of course also dismantling the roof antenna can be effected in that the screw connection is released and the parts are separated from each other when the access to the interior of the body is possible.

An embodiment of the invention, but the same is not limited, is shown in Figures 1 to 5 and explained below.

In the bottom plate 2, a threaded sleeve is provided, in which a designated three screw is screwed. On the baseplate, a spacer sleeve 4 is being worked, so that the screw can be turned only 3 over a certain length. To the spacer sleeve 4 around a designated pressure spring 5 is provided, which is supported at one end on a washer and on the other hand to a bayonet plate designated by 6. On the bayonet plate 6, a sleeve slot 7 is suitable for the spacer sleeve 4 (see Figure 2) is provided, which allows a certain displacement of the bayonet plate 6 to the base plate second Furthermore, bolts 8 are on the bottom plate (in the figures 2 to 4 visible) attached, which pass through slotted openings 9 in the bayonet plate. 6 The bolt 8 and the slot openings 9 are collectively referred to also as guide elements. On the bayonet plate 6 (in particular, see Figures 3 and 4) are further provided projections 10 which correspond in conjunction with a corresponding part of a triangular aperture 11 in the vehicle body 12th To the bottom plate 2 distance elements 13 are furthermore provided, which can protrude into recesses 14 when the bayonet plate 6 relative to the bottom plate 2 has the correct position. The projections 10 on the bayonet plate 6 are assigned to recesses 14 in the bottom plate 2 so that the boundary elements also have the function of the spacer elements. 13 The bayonet plate 6 has at its end an angle surface 15 which is cranked so that it protrudes from the base plate second

As a shown in Figures 1, 2 and 3, the antenna cable 16 illustrates, this may, due to the relatively large triangular opening 11 in the vehicle body 12 can be performed at any point, so that it can be easily assembled prior to attachment of the roof antenna first

In Figure 5, a designated tool 17 is shown which comprises two strips 18 which are secured on a base body 19 to one another. On base 19 handles 20 are also necessary to ensure a good grip of the tool 17th As shown on the right side of Figure 5, the tool 17 can be pushed between the base plate 2 and the vehicle body 12th It thereby lifts the base plate 2 against the force of the compression spring 5 of the vehicle body 12, so that the roof antenna 1 can be shifted so far counter to the mounting direction of the base plate 2 until the bayonet plate 6 by means of surveys 10 and the spacers 13 so far is spaced from the base plate 2 that easy disassembly is possible. The tool is preferably made of soft plastic material, so that no damage to the paint of the car body occurs.
