DE7333792U - Device for displaying a long series of numbers, in particular a telephone number - Google Patents

Description

The innovation relates to a device which allows a longer and therefore no longer reliably to be remembered series of numbers to be displayed in a simple and clearly visible manner and to be deleted after use.

It is known to write down a phone number from a telephone book legibly on a piece of paper and then the Dial numbers by turning the dial on a telephone. This way usually fails with calls from outside of the house, because there is seldom a suitable piece of paper available on which the number to be dialed is clearly legible could be written down. In an emergency, a page of the telephone book or the wall of the telephone booth is then used thus described. To remedy this deficiency, the industry has already developed special devices in which the most frequently used numbers can be stored in large numbers and. by pressing a button fed into the telephone.

but such councils are not only cumbersome, but way too expensive too.

The object of the innovation is to select a device that is as simple and reliable as possible Display number clearly legible and leave it there until the call is made. It must also be possible be to subsequently delete the numbers entered in the device in the simplest way. It is also necessary that the cost of such a device is easily affordable for any private user of a telephone.

According to the innovation, the well-known number discs lined up on a common axis are also used, which have a gear on the side. According to the innovation, however, a drawbar is assigned to each number disc, which is guided transversely to the axis of the number discs and can be pulled out as far as you want with one finger, and whose rack is continuously engaged with the gear of a number disk.

The drawbars should be spaced at least a sufficient distance apart for intended finger operation half the width of a finger and for example by one attached to the protruding end narrow and upwardly protruding lobes can be easily felt. The La? ^ Pen is best in the middle of the drawbar width intended.

The drawbar, for example, has a U-shaped cross-section that is open at the top and a longer leg, which is designed as a rack. Under these circumstances, the number discs can go up to near the shorter Giving ice from the U-shaped section is enough.

A resilient tab is advantageously provided at the inner end of the drawbar and at the bottom of the U, which after outwardly protruding projection is able to lay one after the other in a series of grooves in the housing. To do this, no special part needed. It is sufficient to provide long slots near the legs of the U-shaped cross-section, so that the end of the drawbar can also act as a resilient grid device, which ensures that the Numbers appear neatly in a clear row on the wide number discs.

The drawing shows a device according to the innovation, for example and on a larger scale again, namely shows:

On a fixed axis 1 of a housing 2, which is part of a telephone housing 3 or even just in front of it can be, a number of ring-shaped, wide disks 4 are arranged side by side, each through a Flat gear 5 with hub 6 are mounted centrally and freely movable on axis 1. The width and size of the slices 4 is chosen so that the numbers 0-9 attached to its circumference can be easily seen through a viewing window 7 long distance and can be read safely by the elderly. On the housing 2 are also side by side and arranged transversely to axis 1 according to the innovation drawbar 8 of U-shaped, upwardly open cross-section, the long leg 9 of which is designed as a rack and is permanently in engagement with the gear 5 of a disk 4. The other leg 1o of the U-shaped cross-section is kept as short as possible, so that the number discs 4 as possible can be arranged close to the bottom of the case. Each The end of a drawbar has longitudinal slots 11 along the Legs 9,10 and forms a spring 12, the outwardly protruding, hemispherical projection 13 in Able to insert longitudinal grooves 14 of the housing. The grooves are so far apart that the projection 13 is can only be inserted when the numbers on the discs in the viewing window appear exactly in a straight line.
