DE3730231A1 - Device for a telephone set in the form of a panel - Google Patents

Abstract

Additional devices such as a hands-free telephone device, a printer, a card reader etc. are to be mechanically connected to a telephone set in the form of a panel, the additional devices being constructed as modules having the same cross-section as the telephone set. A connector (2) is provided which has two mutually parallel triangular surfaces which are connected to one another, each triangular surface being bounded by the bottom and the mounting surface of the telephone set. Hook-like projections (4) are fitted on one triangular surface and latch from underneath into corresponding openings (7) in the bottom of the telephone set. The distance between the two triangular surfaces is selected in such a manner that an additional apparatus in the form of a module of the same cross-section can be fitted in a locking manner laterally on the telephone set, which likewise has corresponding openings (7) on the bottom. The device enables the mechanical connection of additional devices in the form of modules of the same cross-section to a telephone set. <IMAGE>

Description

The invention relates to a device for a desk-shaped telephone set, the bottom of which runs parallel to the top and back.

Such a desk-shaped telephone set has already been proposed. So in the Patent application P 36 07 727.5 describes a telephone set, the top of which in Is relatively inclined towards the user, to better usability and To enable readability.

For additional equipment of the telephone set, such as for example a speakerphone Printers, card readers, etc. that are aesthetic For the same cross-section, but possibly one smaller width than the telephone body have, the requirement may exist as modules mechanically with the telephone set housing connect to.

The object of the invention is now a Device for the mechanical connection of such Specify modules with the telephone, where a particularly simple solution is to be sought.

This object is achieved in that the device  from two parallel to each other connected triangular surfaces is formed, each Triangular surface through the underside and the contact surface of the telephone set is limited to the Triangular surfaces hook-shaped projections are attached, which in corresponding openings in the bottom of the Lock the telephone from below and that the Distance between the two triangular surfaces selected in this way is that an additional device in the form of a module is the same Cross-section on the side of the telephone set is conclusive can be attached, which is also corresponding Has openings at the bottom.

The device according to the invention hugs the on both surfaces of the underside of the telephone set, which are parallel to the top and back run. On the side of the triangle which runs parallel to the top of the telephone set, hook-shaped projections are attached, which in corresponding openings at the bottom of the Snap the telephone into place. Are the same openings can also be found on the underside of the module this is attached to the device and by this being held.

A further development of the invention for a telephone set consisting of a lower housing shell with openings, in which resilient webs of the upper housing shell of Snap in at the top is that the hook-like Snap the projections into these openings from below.

The existing openings in the lower housing shell for fastening the device be used.

Such a housing connection is already known. So in DE-OS 30 02 075 a housing for one Telephone set described in which the upper housing shell has resilient webs, which in corresponding openings in the lower housing shell  click into place. There are openings to release the snap connection available, which through the lower housing shell protrude through it with a screwdriver Snap connection can be released.

Further advantages result from the subclaims.

The invention is based on an embodiment explained in more detail. It shows:

Fig. 1 is a side view of the telephone set with the inserted connector,

Fig. 2 is a three-sided view of the device according to the invention and

Fig. 3 details of the attachment of both housing shells with each other and the additional attachment of the device.

The connector 2 has two triangular side surfaces, the surface 5 is limited by the parallel to the top and parallel to the rear underside and the support surface 5 . In the inserted state, the connector 2 nestles so far on the underside of the housing that the telephone set rests with its rubber buffers 13 on the support surface 5 as before. The housing of the telephone set 1 is formed from the upper housing shell 9 and the lower housing shell 10 . On the triangular side of the connector 2 , which runs parallel to the top of the telephone set, hook-shaped projections 4 are attached.

The two triangular surfaces 3 are connected to each other at a certain distance, which is chosen such that when the connector 2 is inserted in the telephone set 1, a module (not shown) can be placed on the free triangular surface, so that the module and the telephone set are connected to one another in a coherent manner.

The upper housing shell 9 is provided with webs 11 , each web having a latching opening 12 . The web 11 slides when the two housing shells 9 and 10 are put together through the opening 7 and engages in the latching lug 6 with its latching opening 12 . On both sides of the latch 6 resilient hooks 8 are attached, which hold the web 11 in the locked position. To solve this mechanical connection, the web 11 can be pushed away from the latch 6 with a screwdriver, the resilient hooks 8 giving way.

The hook-shaped projection 4 of the triangular surface 3 is inserted into the opening 7 and lies against the web 11 and latches with the resilient hook 8 and thus establishes a connection between the connector 2 and the telephone set 1 . By appropriate shaping of the hook-shaped projection 4 , the connection between the connector 2 and the telephone set 1 is releasable because of the resilient design of the hooks 8 of the connector 2 from the telephone set 1 .

The connector 2 according to the invention can have a strain relief for connecting lines inserted into the underside of the telephone set on the side of the triangular surface 3 which lies parallel to the upper side of the telephone set.
