Telephone number directory for desktop telephones.

The innovation concerns a directory of telephone numbers for desk telephones, with one between the telephone and its footprint insertable cassette in which a parallel to its base guided, at least one character carrier which can be pushed in, latched in a straight line against the force of an energy store receiving slide is included.

A known telephone number directory of this type has a housing, the upper cover surface of which is flat Stand area for the telephone is designed and roughened to prevent slipping. The housing is in turn Provided with elastic feet on the floor.

With a mechanical register keyboard arranged at the head end of the housing, when a key is pressed the slide located in the housing can be moved out of this up to a mechanical stop. Included

is the tab of a multi-sheet directory of telephone numbers corresponding to the key pressed hung up.

The space required for the keyboard and its mechanics, as well as the desire for the largest possible writing surface the label carrier, influence the plan dimensions of such a directory, that too with regard to universal usability with its footprint on the floor plan of one of the larger standard telephone models is matched.

This previously known telephone number directory represents an additional device for the telephone, which the long-distance speaker can be assigned as a subset. The disadvantage of such an assignment is that such a directory can be easily separated from the telephone device and can therefore be relocated e.g. when dusting, so that it is not available when needed. Even with spontaneous changes in the location of the telephone it is sometimes felt to be disadvantageous if the directory is a separate part of an additional hand requires. Finally, another disadvantage of the directory described is that of the remote speaker even increased space requirements at the installation site.

Another directory of telephone numbers has been proposed under the name Notice Board. It contains under a transparent protective flap a label holder resting on a base part and is dimensioned so that it is on an approximately flat area of the surface of the housing of the telephone in the field of view can be arranged. The back of the base part of this notice board is intended to be attached to the telephone be self-adhesive coated.

" ³ " ^VPA 78 G 6 15 2 FRG

The capacity of such a notice board is comparatively small. However, it has the advantage of being immediate connected to the telephone and therefore always at hand when making calls. she should mainly used in telephones with a keypad to dial important phone numbers, e.g. for the emergency doctor, to keep the fire brigade ready, as for this purpose the dial of the number switch known insert disk with label holder is not available on a dial pad.

In addition to the emergency calls, you can use the writing surface Such a notice board also has space to note down a limited number of e.g. the individual keys Connections assigned to the dialing facility and which can be automatically established by means of a short number are available being. The dimensions of such a bulletin board are Uoa. due to the arrangement of the controls in the relevant area of the housing surface of the remote speaker.

The disadvantage of such a notice board is that the self-adhesive connection to the housing of the telephone if necessary, can usually only be removed leaving behind adhesive residues that are difficult to remove. Farther It should be noted as a disadvantage that only a few of the currently known telephone models have a sufficiently large, approximately flat, Have free area which is suitable for attaching such a notice board.

The innovation is based on the task of a directory of telephone numbers to create in which the above-mentioned disadvantages of the known directories are avoided,

7823551 16.1178

by incorporating it into the contour of the footprint of the telephone, and making the telephone captive can be allocated by continuing to use it, however, if necessary without leaving any residue from the telephone device is solvable and by putting it in at least one for the inclusion of short numbers and some important Connections of sufficient size on essentially any known model of desk phone without difficulty is attachable.

This object is achieved according to the invention in that the directory of numbers with the contour of his The cassette is adapted to the free space under the floor surface of the telephone, limited by the feet, that the cassette has a flat housing made of base plate and raised side walls, with essentially the upper edges of the side walls directly form the system for the floor area of the telephone, and that the cassette is set up for the releasable, form-fitting connection with the telephone.

A cassette designed in this way remains with its plan within the plan area of the telephone and enlarged thus not the space required at the installation site vertically erected side walls, the upper edges of which are directed towards the floor surface of the telephone, allow the inclusion of protrusions and bumps on the bottom surface of the telephone as well as its Feet in the interior of the cassette housing. This results in an immediate system that saves overall height the cassette on the bottom surface of the telephone case.

The cassette can now have openings oriented perpendicular to the bottom surface for inserting into the

7823551 11/16/78

-5- WA _{78G 6} , 52 FRG

Telephone-engaging fasteners (e.g. Screws). In this way there is a detachable connection between the cassette and the telephone possible by means of the connecting elements penetrating the openings in the cassette. The breakthroughs can also be designed in the form of cylindrical eyes to better guide and keep the To effect fasteners.

According to another development of the invention, the cassette can also with several, the plant level for the The bottom surface of the telephone penetrating, hook-like, elastically deformable in the direction of the contact plane, Oriented to openings in the bottom surface of the telephone, homogeneous material with shaped projections be provided as connecting elements. A cassette made in this way can pass through in the simplest possible way Plugging together to be connected to the telephone, with the. hook-like connecting elements by elastic Deformation can be brought into their positive holding position.

For such a connection between the telephone and the cassette, e.g. those in the floor area are suitable the telephone existing, normally the feet receiving openings. The feet of the telephone can be removed from the ground and, if necessary, in corresponding ones provided in the base plate of the cassette Breakthroughs are used.

On the other hand, z.3. only made use of the screw connection between the telephone and the cassette, so it can be advantageous to leave the feet of the telephone in their receiving openings and to provide the cassette with its own feet from the start. If the feet on the telephone are high enough

and the openings for the feet in the floor area the cassette is aligned with the feet of the telephone and dimensioned accordingly, is also the free passage of the feet of the remote speaker through the bottom surface of the cassette up to down the floor space possible. In this case, the cassette does not need its own feet, but is on the floor of the telephone is suspended.

A latching lever can be provided on the cassette, which has a protruding nose with elastic pretension at one of the edge areas extending in the direction of movement of the one received in the cassette Slide is applied. The edge area of the slide that interacts with the locking lug can simultaneously be provided with at least one recess that enables the latching lug to collapse. Will the slider now pushed into the housing against the force of the energy store, so it can be in the deepest insertion position a latching take place. When this latching is triggered, the stored energy settles in motion, the slide is moved out of the cassette and steps out of the floor plan area of the remote speaker emerged. In this outer position, the slider assumes a position in which the phone numbers containing label carrier is fully visible.

The locking lever can extend away from the cassette in its The end area can be designed as a handle for triggering the latching under the telephone device protrudes and is easily accessible from the outside in this way. The locking lever can be homogeneously material on the Housing of the cassette be molded. The elasticity of the base material of the housing, e.g. insulating
