Description

The invention relates to a holder for clamping assembly.

For many applications, it is known to attach panels for the assembly of technical equipment to a frame.

For example, e.g. From the field of training known to mount on suitable frame changing port for training and / or instruction and so to practice the assembly of technical equipment. A major problem is that these panels are changed frequently, so quick change is of great importance.

Also from other areas such exchangeable panels are known.

However, in many previous solutions, the changeability was only cumbersome and time-consuming.

The invention is based on the object to provide a novel holder for clamping assembly that avoids a disadvantage or several disadvantages of the prior art.

The object is achieved according to the invention by the features of the independent claim. Advantageous embodiments of the invention are specified in the subclaims and the description.

The invention will be explained in more detail with reference to the accompanying drawings with reference to preferred embodiments.

Hereinafter, the general operating principle and an embodiment of the invention will be explained in more detail with reference to the figures.

In this case, the same reference numerals are usually used for similar components.

As far as the singular is used below, as a rule, the invention is not limited to an element, but will be described by way of example only with reference to an element.

In 1 is a sectional view of the principle according to the invention in an unclamped state shown in 6 the clamped state is shown. Correspondingly, in 9 Sectional views shown in an unclamped condition while in 11 the clamped state is shown

In this case, a holder according to the invention 1 for clamp mounting on a first fixed section A _f . This section may be independently attached to or integrated into a frame or other mounting surface. This section is schematic in 2a shown individually.

Furthermore, a holder according to the invention 1 Also, a movable portion A _b , which is movable about an axis of rotation relative to the fixed portion A _f . This section is schematic in 2 B shown individually.

The axis of rotation also provides the support of the movable portion A _b at the fixed portion A _f available.

The movable portion A _b is rotatable relative to the rotation axis relative to the fixed portion A _f by a preset angle of less than 360 °.

The axis of rotation can be realized, for example, by corresponding bores B in the movable section and in the fixed section, wherein an axis is inserted in the bore, which also serves as a rotary element S.

This can eg in the 4 and 5 as well as 10a - 10d can be seen, in each case a rotation of 180 ° is shown here by way of example.

To prevent rotation beyond the preset angle, a stop F is provided.

This stop can be achieved by (pluggable) pins that attach to a holding surface / retaining block F as in 7 shown strike or be realized by preformed attacks.

If pins are used in connection with the stop F, e.g. by specific insertion of the pins in corresponding holes different angle presets can be realized.

The movable portion A _b is fixed relative to the fixed portion A _f by means of a rotary member S. This rotary element S also forms the axis of rotation here.

The exact shape of the rotary member S will be explained later.

A rotational movement of the rotary member S now causes the movable portion A _b can rotate relative to the fixed portion A _f to the stop F, with a further rotational movement causes a tightening of the movable portion A _b to the fixed portion A _f , so between the movable portion A _b and the fixed portion A _f an object can be clamped.

This reduces as from the comparison of 1 and 6 respectively. 9 and 11 can be seen the distance d, ie here an object, for example, the panels mentioned above can be clamped.

It is of particular advantage that the mechanism according to the invention makes it possible to support an object with only one (rotational) movement. In this case, the construction is designed so that in the non-clamped state, the movable portion A _b can be arranged relative to the fixed portion that the object G could not only be inserted laterally, but also inserted from the front or forward, ie in Direction of the axis of rotation, can be taken as in 11 indicated by the double arrow.

It should also be noted that the functionality is independent of the spatial orientation or gravity, so that similar brackets can be used in other spatial positions with the same properties.

That With the solution presented, it is particularly easy to secure objects and especially panels safely, the attachment and the solution of the attachment can be provided without tools even with a suitable shape.

Without limitation of generality, the holder can 1 be made of different materials.

In one embodiment of the invention, the holder 1 further comprising means for attaching the holder to another object, wherein the means for attachment is a first fixed portion of the holder. That is, the fixed portion may for example be provided with a suitable bore through which a fastening screw for attachment to the other object, such as a frame or a wall can be performed.

As previously written can with the holder of the invention 1 An angular range of less than 360 ° can be addressed. However, the preset angle can be 270 °, 180 ° or 90 ° in a particularly simple and advantageous manner since, with a suitable embodiment, a frontal removal / a frontal insertion (ie in the direction of the axis of rotation) can be made possible in the movable section A _b ,

As stated previously, the holder according to the invention 1 be suitable for mounting switch panels, breadboard plates and the like held as a clamping object. In this respect, the holder has no limit.

In a particularly advantageous embodiment may also be provided that by the holder 1 an electrical conductive connection is provided from or to the clamped object G. For example, this can be used to provide a certain potential, for example the potential PE. Although the holder has been previously described for the assembly of panels, but the holder can also be used in general for fast connection of conductors to busbars or the like, ie the "fixed object G" would then be the busbar. In this case, it may also be provided, for example, that the rotary element S is at least partially non-conductive, eg equipped with a non-conductive rotary knob DK and / or other contact protection elements.

As already indicated, the rotary element S can be designed differently. For example, the rotary element S can be designed as a screw. Alternatively, however, the rotary element S can also be designed as a rotary knob DK and a threaded rod. Of course, mixed forms may also be provided.

The embodiment with a rotary knob DK and a threaded rod S, which is rotated by the rotary knob DK allow a particularly simple tool-less operable design. Alternatively, a corresponding attack possibility can also be provided by a large screw head so that a tool-free, operable embodiment can also be realized.

The following should be further on the 7 to 11 To be received.

In 7 is an exploded view of an embodiment with knob DK shown. The knob DK is connected to a threaded rod S, which can be actuated thereby. On the threaded rod S is a compression spring D. One or more pins provide in connection with a stop F (or more stops), the inhibition of further rotational movement available. The different elements can also be repeated in relation to the in 8th shown sectional lines (frontal view of the knob DK) in the 9 be seen.

The exemplary movement sequence when clamping is from the 10a -D can be seen. For example, put 10a a starting position, wherein the movable portion 180 ° relative to the clamping position, shown in 10d , is pivoted. In the starting position, for example, an object G can be inserted into the clamping area (distance d). Now turn the knob clockwise (depending on the thread of the rotary member), as from the 10b and 10c can be seen, so first, the movable portion A _b rotates until the clamping position is reached. However, further rotation is prevented by the stop F, so that any further rotation leads to a decrease in the distance d, whereby at the end the movable section in the clamping position is pulled / pushed so far against the fixed section that the distance d becomes so small, that a clamping of the object is provided. In the opposite direction can then be increased by turning counterclockwise (depending on the thread of the rotary member), the distance, so that the object can be removed again.

That the rotational movement causes the movable portion to be attracted even while the movable portion is being pivoted.

Turning the rotary knob DK causes a change in the clamping path. At the same time, the movable section is pivoted to a defined section. The turning of the actuating knob can take place beyond the stop position of the movable stop, up to the end of the clamping l (see 11 ).

The pivoting can take place here via a resilient pressure piece S, which sits in the movable section A _b , and engages in a notch / recess in the rotary knob DK. Once a stop F (off or swung in) is reached, the movable section A _b can not move, but the knob DK can be further rotated because the resilient pressure piece is pressed.
