Description

[Detailed description of the invention] The invention comprises a casing bounded by a substantially rectangular wall, at least one switchboard assigned to the casing wall, and at least one character field assigned to the switchboard. and a cover for protecting a character field, which is releasably connectable to the casing wall.

Using a power control board with power keys arranged in a row for good visibility, multiple recording mechanisms can be used to display different recording formats on different tracks or to perform the same type of recording. Various types of recording devices are known that operate selective or single recording mechanisms. Recording devices of this type are used in particular for recording the operating state of production machines, for example, where changes in the operating state need to be carried out systematically.

Although we ignore that the recording device provided for such a recording format must of course also have corresponding technical suitability, it is important to characterize each electronic key on the electronic keyboard in such a way as to avoid confusion. It is necessary. In this case, it is not enough simply to provide the power key with some kind of code, but it must also be provided with a descriptive text indicator. Since this marking necessarily varies depending on the area of installation and the user, it cannot be attached directly to the casing of the recording device, but on the contrary must be replaceable in a corresponding form, and the necessary markings A dial shall be provided with a Additionally, these types of recording devices are often installed in extremely harsh environments.
The dial or character field must be protected against dirt. That is, a corresponding cover for the character field must be provided.

To compensate for this limitation, each power key is usually provided with a flat, transparent cassette that can be connected to the casing or to the corresponding casing wall, into which the respective dial is fitted. ing. However, arranging the dial in this way is not only expensive but also extremely inappropriate, since on the one hand the dial must be cut to a relatively precise fit and on the other hand the casing The uneven front surface of the recording device, limited by the mounted cassette or dial casing, makes it difficult to clean. It is also known to provide a transparent hood over the entire character field. The hood is fixed to the housing, for example, by means of a corresponding screw connection. In this case, even ignoring the low cost, this solution also suffers from the drawbacks already mentioned. Furthermore, disadvantageous aesthetic effects, particularly on the front side of the recording device, have to be taken into account. This is the case, for example, with the screw connection of the cover located in the area of the character field and the fact that: This means that the power key must protrude further from the casing due to the hood than is necessary for the power key switching process.

The object of the invention is to avoid the aforementioned drawbacks of the solutions known up to now, to ensure that the costs of replacing the dial are low and, in particular, that the cover obtained does not involve additional technical outlays. It is an object of the present invention to provide a cover for a dial in a recording device as mentioned at the outset, which joins harmoniously to the front surface of the recording device without any problems.

To solve this problem, the present invention provides that at least one wall area occupied by the power switchboard and the character field on the front side of the casing wall, to which the power switchboard and the character field are assigned, is A cover is formed low to the front side of the casing wall and has an opening corresponding to the contour of this low wall area of the casing wall and is assigned to each power key. It is configured so that it can be connected to the casing wall so as to be substantially flush with the front surface.

An advantageous embodiment of the invention provides that the cover is formed as a flat plate of transparent material, and at least one of the longitudinal or lateral dimensions of the cover approximately corresponds to one of the longitudinal or lateral dimensions of the casing wall. Equally, the cover is screwed on the one hand at at least two symmetrically opposite corners of the casing wall and, on the other hand, by a bayonet connection acting between the cover and the casing wall, A window, in which an opening for the power key is assigned, is formed by a colored mask attached to the cover.

Thereby, the advantages of the proposed solution are:
This means that the dial type can have large tolerances. This is because the outline of the dial is faded out by a window in each cover. The same thing is
This also applies to at least the opening assigned to the power key in the casing wall.

Moreover, the solution according to the invention, in particular with respect to the fixing of the cover, makes use of pre-existing fixing positions, additionally avoiding threaded connections that disturb the aesthetic impression, and allowing multiple fixings to be carried out by one or the same part. It is possible to cover or protect the display member and the character field from dirt.

The more or less uniform or uniform planar arrangement of the cover obtained by the invention has the advantage that the power key only needs to protrude from the front face of the recording device by its control stroke. There is.

Next, the configuration of the present invention will be specifically explained with reference to the embodiment shown in the drawings.

The housing of the recording device shown in FIG. 1 has an approximately rectangular contour, whereby the front surface is also rectangular and can be formed, for example, by a base (not shown) or a mounting plate and a hood. The hood is preferably screwed to the mounting plate in the area of the corner formed by the side wall. One of these screws is designated 2 in FIG. Through the window 3 fitted in the hood 1 it is possible to see a recording disk, which is not shown as it is not necessary for the invention, whereas the recess formed in the front hood or casing wall 5 is marked 4. The bottom of the recess 4 is provided with further cutouts 6, each of which is used to receive a dial 7, which itself is arranged in one or more rows or groups. Used to attach symbols to the various electric keys placed. One of the various electric keys is designated by the numeral 8. This power key or keys are used, as already mentioned at the outset, in the illustrated recording device for manually controlling the recording mechanism or for selecting a recording step. Furthermore, additional mechanical structures include a control panel, indicator lamps 9, 10, a display board (not shown in detail) for displaying selected values, and for adjusting various operating states for exclusive use. Switchlock 11 is assigned.

Corresponding to the contour of the recess 4, in particular the protective cover 1
A flat plate of transparent material, assigned as 2 to dial 7, can be connected directly to screw 2 by means of screws 13, 14, as shown in FIG. 2, as well as a corresponding bayonet connection. It is connected to the casing wall 5 by a section 15 . In the illustrated embodiment, this plug connection 15 consists of a plurality of wedge-shaped extensions (not shown in detail) formed on the end side of the cover 12 and a plurality of wedge-shaped extensions in the housing wall 5 assigned to these extensions. It is formed from an undercut part. In this case, this arrangement is such that the cover 12 forms a flat, coplanar surface with the remaining surface of the casing wall 5 or, to put it differently, the outer surface of the cover 12 is approximately the same as the casing wall 15.
It is positioned in the plane of the front surface of the

Of course, for example, an opening 16 is formed in the cover 12, and through this opening 16, buttons as the power key 8 of the power control board, display lamps 9, etc.
10 protrudes or is easily accessible to the switch lock 11. The device-side surface of the cover 12 is further covered with an opaque layer, such as a colored layer. In this case, the windows assigned to the dial 7 or the display panel, for example 17, 18, or the adjustment markings 19 assigned to the switch lock 11, as well as the text display parts, not shown, are cut out of the colored layer. Furthermore, a corresponding sealing element may be provided between the cover 12 and the housing wall 5. Furthermore, the indicator lamps 9, 10 are arranged in a covered manner and emit light only through windows provided in the colored layer of the cover.
