DE3046247A1 - Telephone set having chassis in two-part casing - holding various additional devices such as loudspeaker and memory, and boards - Google Patents

Abstract

The telephone set has additional attachments like an answering device, a loudspeaker, a memory etc. incorporated into its casing to form an easy-to-use, readily-repairable unit. The casing consists of an upper part (1) and a lower part (6) enclosing between them a chassis (7). The chassis holds all the components (3,5,9,10) and has guide rails for slide-in circuit boards (9). The casing and chassis are always the same regardless of the additional functions incorporated.

Description

Telephone set, in particular

Convenience device The invention relates to a telephone set, especially comfort device, with additional functional elements, such as answering machines, Loudspeaker device, memory, speakerphone or the like, where the Elements are received by the housing and essentially covered.

In the case of arrangements of this type, the housing serves as a holder for the individual functional elements, which are arranged depending on the embodiment. Here a distribution of the elements on the base and cover is made. Because of the increasingly complex technical equipping of these telephones is with Checking or repairing the functional technical unit as a whole is difficult to investigate and make substitutions so that for this Appropriate aid measures are required for the purpose.

The object of the invention is to provide a telephone set according to the To create a generic term that is easy to use and accessible for assembly as well as for technical testing and repair including Retrofitting guaranteed, with additional functionality even without a housing is made possible.

This object is achieved in that the housing is used as a receptacle is formed from an upper and lower shell, between which a chassis-type The carrier part is arranged and can be fixed via retaining ribs and that the carrier part Holders and connections for all structural and functional elements in the form of a frame having.

This has the advantage that the housing and support part are independent of the requirement purpose are always the same and therefore a functional test without Housing is feasible. This separation from the housing also represents a simplification for a repair and for retrofitting or retrofitting. With this type of construction arise thus no difficulties for housing and accessibility of the building and Functional elements in telephone sets, the prescribed bevels for Have fulfillment of ergometric requirements.

Correspondingly standardized for inserting and replacing Printed circuit boards it is proposed that the carrier part be used as receptacles Pttlhrungsschienen for functional elements in the form of printed circuit boards at a standardized distance.

For good use of space it is provided that several guide rails are arranged one above the other and side by side.

In the drawing is an exemplary embodiment of a comfort device shown schematically in the form of an exploded view, with individual circuit boards are partially pulled out.

The telephone set shown consists of an upper shell 1 with a passage opening 2 for a key pad 3 and a receptacle 4 for one Receiver 5 and a correspondingly assigned lower shell 6. The upper and lower shell 1 and 6 can be coupled to one another via holding elements not shown in detail, so that they are firmly connected to each other.

The Ge-Muse formed from the upper and lower shell 1,6 takes a support part 7, the individual carriers 8 also serving as retaining ribs.

The carrier part 7 takes all structural and functional parts via its carrier 8 in the form of circuit boards 9 or directly elements, such as a hook switch 10 and keypad 3. The carriers 8 are in the form of rails that Form 11 recordings with knobs. This allows circuit boards 9 to be exchanged quickly or additionally included.

It is intended to take pictures in several levels one above the other and next to one another to arrange. The distances correspond to the standardized printed circuit boards 9.

By equipping and connecting the handset 5 in or on the independent Carrier part 7 creates a functional unit that has no upper and lower shell 1 and 6 is easily accessible and an easy replacement or addition of circuit boards 9 enables. The internally functional support part 7 is then through the upper and lower shells 1 and 6 included as a housing.

Claims (3)

Patent applications telephone set, especially comfort set, with additional functional elements, such as answering machine, loudspeaker device, memory, Hands-free device or the like, the elements being received by the housing and are substantially covered, characterized in that the housing as Receiving container is formed from an upper and lower shell (1,6), between which a chassis-like carrier part (7) is arranged and can be fixed via carrier (e) and that the carrier part (7) receptacles and connections for all structural and functional elements (3,5,9,10) in the manner of a frame. 2. Telephone according to claim 1, characterized in that the carrier part (7) as receptacles guide rails for functional elements in the form of printed circuit boards (9) at a standardized distance. 3. Telephone according to claim 2, characterized in that several guide rails are arranged one above the other and next to one another.
