rThe present invention relates to the design of the case for such subscribers telephones in which the support for the micro-telephone 'is made integral with the case. Such cases ,i
are inostl made of a mouldable mass, for in stance ba elite. Elevated parts on the upper side of the case form supporting ribs for the micro-telephone which supporting ribs are provided with notches in which the microtele hone is intended to rest. For the convement handling of the apparatus it is desirable to make said notches comparatively shal low so that the micro-telephone, when relaced, will easily fall down into the notches.
n the other hand, it may easily happen in known case designs that through carelessness on the part oi the using erson the microtelephone, upon bein quidlxlyreplaced, will perform a rapid oscl lation about its longitudinal axis, the inert masses of the microphone box and telephone receiver box then causing, under certain contingencies, the sli ping out ci? the micro-telephone from the comparatively shallow notches.
According to the present invention said inconvenience is overcome thereb that the side faces o' the case and/or of tile supporting ribs for the micro-telephone are bent outwards at the rear end of the case in order to prevent an oscillation of the micro-telephone about the axis of the handle, so that through this shapin of the case stops are formed for the microp one and for the telephone receiver. The tendency of the micro-telephone to oscillate rapidly upon being replaced will hereby be eectively counteracted, a holdingl device for the micro-telephone being thus provided which works safely also upon careless handling.
'lhe invention will be more ful-ly described with reference to the accompanying drawings. Figure 1 is a lon itudinal section through a subscribers telep one case according to the invention. Figure 2 shows a section through the case on the line 2-2 in Figure l with the micro-telephone resting on the case. Figure 3-is a top plan of the telephone y case with appertaining micro-telephone.
The support or resting place for the microtelephone 5 is formed by elevated portions 809,888, and in Germany April 4, 1931.
2, 3 on the upper side of the telephone case 1, which elevated ortions narrow off in the direction upwar s. The said elevated portions are made in the form of elongated ribs the outer sides of which merge into the side faces of the telephone case. Each of the ribs 2, 3 is provided with a notch 4, the two notches serving as supports for the micro-telephone 5. ln the lower part of each notch is disposed a push button or a push rod 6 which is adapted to move reely in a vertical bore 7. The lower ends 8 of said push buttons or push rods engage an elasticall supported contact arm 9 in the interior o the apparatus, the push buttons or push rods being pressed ulpwards by means of a spring 10 acting on t e arm 9.
When placing the micro-telephone in the position on the case intended or this pur pose the buttons 6 will be pressed downwards causing the operation of the contact in the interior of the case.
As will be seen from rear ends of the ribs 2, 3 are bent outwards and a corresponding bend of the side faces of the case hasalso been made at the rear of the latter. rlhrough this shaping of the case the microphone box and the rear stops for telephone receiver box are formed whereby an oscillation of the microtelephone on the case are eectively prevented.
As shown in Figure 2 there is provided sufeient room between the'two ribs 2 and 3 for the micro-telephone to be easily grip ed with the hand. As will be seen from the rawings the outer faces of the case are formed in such a way, that of two horizontal sections through the case taken at different levels the` outline of the uppermost section will always lie inside the outline of the lower section. Hereby is attained that the case with its micro-telephone supports may be made in' a single manufacturing operation.
l. A telephone desk set comprising a casing. a hand telephone having a receiver box and a microphone box at the ends of a handle, a hand telephone support on the top of the casing, and extensions of the side walls of the casing located close behind and forming stops Figures 2 `and 3 the' for the receiver box and the microphone box respectively to revent swinging movements of the hand te ephone.
2. A telephone desk set comprising a casing, a han telephone having a receiver box and a micro hone box at the ends of a handle, a support or said handl telephone and extenslons of said sup ort located close behind and forming stops or the receiver box and the microphone box respectively to prevent swinging movements of the hand telephone.
