Abstract
Abstract An antenna foot for a movable antenna comprises a dish-shaped holder (1) of magnetizable material and a securing element (2) for an antenna (3) on the top of the holder. In the dish-shaped holder there is placed an annular, permanent magnet (4) secured at a distance from a central magnet yoke (5) and at a distance from the edge of the dish-shaped holder. Permanently secured along the edge of the dish-shaped holder is an encircling protective element (6) of yielding material, preferably in one with the binding material (11) which secures the magnet (4) at a distance from the edge of the holder (1).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
95 words
Antenna foot for movable antenna comprising a dish-shaped holder (1) of magnetizable material and with securing element (2) for an antenna (3) on the top side, a permanent magnet (4) secured in the dish-shaped holder and a magnet yoke (5), and where the underside of the antenna foot is provided with a protective element, characterized in that the protective element comprises at least one encircling item (6) of yielding material permanently secured to the dish-shaped holder (1), and configured in such a manner that it extends out over the lower edge (7) of the holder.
Claim 2
Dependent Claim
95 words
Antenna foot for movable antenna comprising a dish-shaped holder (1) of magnetizable material and with securing element (2) for an antenna (3) on the top side, a permanent magnet (4) secured in the dish-shaped holder and a magnet yoke (5), and where the underside of the antenna foot is provided with a protective element, characterized in that the protective element comprises at least one encircling item (6) of yielding material permanently secured to the dish-shaped holder (1), and configured in such a manner that it extends out over the lower edge (7) of the holder.
Claim 3
Dependent Claim
40 words
Antenna foot according to claim 1, characterized in that the item (6) of yielding material is configured with such a cross-sectional profile (6,10) that it covers the annular lower edge (7) of the dish-shaped holder and is permanently secured hereto.
Claim 4
Dependent Claim
38 words
Antenna foot according to claim 1 or 2, characterized in that the item (6) is configured in one with the means (11) which is used to position and secure the permanent magnet (4), which is an annular magnet.
Claim 5
Dependent Claim
27 words
Antenna foot according to claim 3, characterized in that the item (6) and the means (11) are of the same material, preferably a thermoplastic rubber or resin.
Claim 6
Dependent Claim
35 words
Antenna foot according to claim 1 or 2, char acterized in that the item (6) is an independent, encircling profile ring which is permanently secured to the holder (1), e.g. by gluing or hot welding.
Claim 7
Dependent Claim
41 words
Antenna foot according to claim 1 or 2, characterized in that the item (6) is an independent, encircling profile ring (fig. 3) which is secured by a further dish-shaped holder (13) which wholly or partly surrounds the first-mentioned dish-shaped holder (1).
Claim 8
Dependent Claim
40 words
Antenna foot according to claim 1 or 2, characterized in that the item (6) is configured in such a manner that wholly or partly it surrounds and covers the whole of the upwardly-turning outer side of the dish-shaped holder (1).
Claim 9
Dependent Claim
82 words
Antenna foot according to claim 1, characterized in that the magnet is a ring magnet (4), and in that centrally herein there is disposed a magnet yoke (5) which, together with the holder (1), comprises the magnetic circuit, and that between the parts there are annular slots filled out with binding material (11,12), and in that the yoke (5) has a central hole for a securing element (2) for an antenna (3), said securing element also securing and positioning the yoke (5).
Claim 10
Dependent Claim
75 words
Method for the manufacture of an antenna foot according to claims 1-4 or 8, characterized in that the dish-shaped holder (1), a magnet item (4) and the magnet yoke (5) with securing element (2) are placed and positioned in a mould (14), after which the mould is closed with the mould parts (15,16) arranged so that the parts are cast in by injection moulding at the same time that the encircling item (6) is formed.
Claim 11
Dependent Claim
42 words
Method according to claim 9, characterized in that the underside of the antenna foot within the encircling item (6) is cleaned and possibly turned, after which the area is covered with a thin foil or coating and the magnet item is excited.
