Description

• · ■ f ·

The invention relates to a frame for attaching display instruments , in particular measuring instruments, to control panels or device housings.

It is known to display instruments in particular in sections of control panels or device housings To use measuring instruments. To attach these instruments to the associated wall parts are a Variety of fasteners known. These Fastening elements are generally formed in several parts and are with the corresponding Instrument connected. This known multi-part design of the fastening means is expensive and assembly is difficult because of the limited space. Especially with switchboards, where several instruments next to or on top of each other need to be attached, the previously known fasteners require either wide Intermediate webs between the recesses for the individual instruments or additional assembly aids for actuating the fasteners. In general, these fasteners are associated with the Measuring instrument connected or connectable, so that the housing of these instruments for the arrangement or Connection of the fastening means must be specially designed.

Additional difficulties arise when a display or measuring instrument is replaced shall be. It is often required that the cutout in the control panel or in the corresponding Housing of another device is covered by a frame or the like. this

requires additional fasteners for the Frame in the cutout and on the instrument.

The invention has for its object to be a Frame for attaching display instruments, in particular to create measuring instruments on control panels or device housings, the easier structural design enables quick and easy attachment of a display instrument.

According to the invention, this object is essentially achieved in that eccentric clamping disks are provided, which are provided with mushroom-like pivot and bearing bolts and in openings on the side Frame walls are used, and that on a surface of the eccentric clamping disks and on the Frame walls locking elements are provided.

Due to the design according to the invention, the fastening means are with an independent frame connected, which can be used by itself in the control panel or in a device housing. Through the According to the invention, it is possible to close the side walls with the eccentric clamping disc in this way dimensioned so that their common height is not greater than the width of the frame. This makes it possible For example, in a control panel, the respective display or measuring devices directly next to one another to arrange.

According to an advantageous embodiment of the invention, the locking elements are the eccentric clamping disc as a circular, radial, sawtooth-like ribs formed.

The blocking elements are advantageous for this purpose the frame wall as a circular ring-like arrangement, radial ribs formed.

This training ensures that the eccentric clamping disc around the axis of the rotary and The bearing pin can only be rotated in one direction, while an automatic one in the opposite direction There is a lock.

The frame according to the invention is therefore only by rotating the eccentric clamping disks on a Control panel or attached to a device housing.

To facilitate clamping, it is advantageous if there is one on the circumference of the eccentric clamping disc straight section is provided as a handle bar.

According to a further embodiment of the frame according to the invention, the eccentric clamping disc has their edge, at least over part of their circumference, a knurling.

To facilitate the connection of the eccentric clamping disc with the frame it is advantageous if the mushroom-like pivot and bearing pin is designed in the shape of a truncated cone and in a conical shape Storage is locked rotatably in the frame wall.

A particularly useful connection between the frame and the eccentric clamping disc then results if the pivot and bearing pin through an opening arranged in the frame wall, the diameter of the opening is slightly larger than the diameter of the bolt, inserted and along the frame wall

via a knot in an as a Bolzr-nsi tz ausyebildotes The layer is elastic and is nyo-pressed.

For receiving and holding the display resp. Measuring instruments are in practical white sidewall strips fen provided as holding surfaces. These sidewall strips are designed such that the Frame walls with the eccentric clamping disks are elastic are pivotable. To connect the frame with the measuring instruments are advantageous Way on the frame walls inwardly directed notches to hold the display or measuring instrument intended.

This training makes it possible that in a, already clamped in a wall, Mounting frame any measuring or Indicating instrument can be inserted in a simple manner. For holding the display and The measuring instrument then does not require any additional holding means, such as screws or the like, so that the fastening solely by the elastic forces of the frame wall parts is achieved.

Further advantages and features of the invention are explained in more detail with reference to the drawing. It shows:

In Pig. 1 is a frame 1 according to the invention shown, for example in a section 22 of a control panel wall 9 is inserted. The frame 1 lies with a circumferential Edge strip 16 at the edge of the cutout 22 at =

The frame 1 has side frame walls 2 and 3, which are parallel to each other approximately perpendicular to the Wall 9 run. On the frame walls 2, 3 eccentric clamping disks 5 are integrally formed with the aid Pivot and bearing pin 4 attached. The frame 1 preferably has side wall strips on the longitudinal sides 19, which are used to hold a display or measuring device 21. To fix the display or Measuring device 21 are used on the side frame walls 2 and 3, preferably integrally formed one-piece detents 20.

In Fig. 2 is an eccentric clamping disc according to the invention 5 shown in front and rear view and in side view. The eccentric clamping disc 5 has a curvilinear outline, with part of the circumference being preferably straight Section 10 is formed, which facilitates the rotation of the eccentric clamping disk 5. This one This purpose is also served by a knurling 11 on the circumference or the edge of the eccentric clamping disk 5 may be appropriate.

On one side that is opposite a side frame wall 2 or 3 in the fully assembled state, are locking elements 6 in the form of sawtooth-like, radially extending, circular ring-shaped Ribs 8 provided. These ribs 8 act with radially arranged locking elements 7 (Fig. 3) in or on the wall surfaces of the side frame walls 2 and 3 together. The training is included taken in such a way that a rotation of the eccentric clamping disk 5 is only possible in one direction of rotation
