AI Technical Summary
Existing methods for attaching a device to a telephone handset, such as using suction cups or adhesive pads, are impractical and difficult to implement.
A two-part housing with an articulated lug that can be hooked onto the middle part of the telephone handset via elastic deformation, allowing easy installation and removal without modifying the handset.
The articulated lug provides a practical and secure attachment method for devices like deodorant and disinfectant tablets on a telephone handset, enhancing usability and convenience.
Abstract
Description
In the main application filed at INPI Paris on November 29, 1988 under No. 88 15587, a device comprising a two-part housing containing a filter, which can be removably attached to the receiver or transmitter of a standard telephone handset without the need to modify said handset. The aforementioned device was attached to the telephone handset using suction cups or adhesive pads. Experience has shown that these methods of attachment are impractical and difficult to implement. According to the present invention, one of the two parts of the housing includes an articulated tab capable of hooking, by elastic deformation of the material constituting it, onto the middle part of the telephone handset. The invention will be better understood from the following description, made with reference to the attached drawing, which is provided as an illustrative example only, in which Figure 1 is a perspective view showing the housing of the invention in the position of use; Figure 2 is an elevation view showing the case in the non-use, or storage, position; Figure 3 is a cross-sectional view, taken along the line III-III of figure 2. The elements already cited in the main patent application will be assigned the same references. As described in the main application, the device consists of a two-part housing, parts 1 and 3 respectively, in which is housed, for example, a deodorizing and disinfecting tablet Z According to the present invention, part 3 of the housing, referred to as the "lid" in the main application, comprises a hinged tab 6 According to one embodiment, the leg 6 has a fork 7 whose ends are folded inwards at 7a. The lug 6 constitutes the fixing element of the housing 1-3 on a conventional telephone handset whose fork arms 7 can grip the middle part M of said handset (figure 1). The housing is put in and taken out by elastic deformation of the material constituting the fork 7. Preferably, the leg 6 is articulated between the wings 8 of a clevis fixed to the cover 3 and it has laterally trunnions 9 capable of being elastically engaged in a housing provided in the inner faces of the wings 8. For this purpose, the plate 6 has a notch (figure 2). In the storage position, the 6-7 leg fits into a recess 11 provided in the outer face of the lid 3. Of course, the present invention is not limited to the embodiment described and represented but extends, on the contrary, to all variants of shapes and dimensions.
Claims
DEMANDS 1- Device according to claim 1 of the main application, characterized in that one of the two parts (1-3) of the housing has an articulated tab (6) capable of hooking, by elastic deformation of the material composing it, onto the middle part (M) of a standard telephone handset. 2-Device according to claim 1, characterized in that the leg has a fork (7) whose ends (7a) are curved inwards. 3-Device according to any one of claims 1 and 2, characterized in that the external face of one of the two parts of the housing has a recess (11) in which the tab (6-7) is housed in the storage position.
