ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a support mechanism for a portable radio communication receiver, notably a portable telephone, formed by transport and positioning means for transporting said receiver clipped onto a piece of garment or a belt and for putting the receiver in upright position on a piece of furniture.
The invention likewise relates to a radio communication receiver including a support mechanism.
The invention is applied, inter alia, to cellular telephones.
So far, cellular telephones and other cordless telephones also called mobiles or portable telephones and called device or receiver in the following text have come to a sufficiently small size to be transported by a user, clipped onto a belt or even a piece of garment, or in a pocket. For such a way of transport, however, one has to take care that the device does not come loose too easily. For this purpose, there is generally provided a retaining clip mostly arranged on the back of the device, while this clip is intended to fasten the device to the belt or to the pocket containing it.
Another support function of the device consists of putting it on a table in an ergonomic manner, that is to say, in a more or less inclined position rather than horizontal position. In this manner, the display of the device can be read better and it is easier to fetch when one wishes to handle it.
Moreover, such a position is advantageous for good transmitting/receiving conditions of the antenna.
The invention is put in a context where one wishes to provide the two cited support functions, against a user and on a table.
BACKGROUND OF THE INVENTION
In the known devices which comprise a mechanism with the two support functions, these two functions are most often differentiated, the mechanism comprising two elements which are clearly separated and the two of them slewed substantially at the same location situated on the upper back part of the device. With regard hereto may be cited U.S. Pat. No. 5,590,860 whose relatively complex mechanism comprises four elements among which the two clearly separated elements cited above referenced
20
and
30
and which substantially have the same length. The element
30
may occupy various angular positions relative to clip
20
which permits of placing the device to which the support mechanism is fixed on a plane in various inclinations of the order of 30 to 40 degrees. This mechanism is complex and thus costly and fragile. The inclinations it provides are closer to the horizontal than to the vertical.
It is an object of the invention to provide a support mechanism which is both simple and robust.
Another object of the invention is to provide a support mechanism which permits of positioning a portable radio communication receiver on a table in a position that is close to the vertical.
SUMMARY OF THE INVENTION
For this purpose, the support mechanism described in the opening paragraph is characterized in that said transport and positioning means comprise a clip intended to be fastened by a first fixed end at the top of the back face of said receiver and a tilting member which pivots around a shaft arranged at the second elastically movable end of said clip.
The clip of conventional structure like that of the cap of a fountain pen, for example, is suitable for withstanding shocks.
An advantageous embodiment of the invention consists of the tilting member which has two end positions, one folded end position in which it is closed in by said clip in view of transport, and a completely unfolded position in which it may serve as a support member on a horizontal plane for the receiver in a position of the receiver close to the vertical.
Other relative turning positions between the clip and the tilting member permit of obtaining more inclined and more stable positions of the receiver.
Preferably, the relative positioning means of the clip and the member are formed by ridges which co-operate with recesses of complementary form, the ridges and the recesses being provided on and in side faces of the clip and of the opposite member in the proximity of the shaft.
According to a preferred embodiment of the invention, the clip is in the form of a fork having two prongs and the tilting member occupies the space situated between the prongs in its folded position in which it is closed in by the clip.
Preferably, the clip and the member are made of polyamide such as nylon or rilsan or made of polypropylene and manufactured by hot injection molding.
