Description

Holding device for a panel element

The present invention relates to a holding device for a panel element, in particular for an infrared heating panel, according to the features of the preamble of claim 1, a mounting device for mounting a holding device on a fastening base and a manufacturing method for a holding device.

Devices for assembling panel elements are basically known in the prior art, for which reference should be made, for example, to DE 1960887 A1.

The use of expanded glass with infrared-based heating elements is also generally known, for which reference should be made to DE 102013003155 A1.

Devices for mounting radiators are also known, reference being made, for example, to DE 60010565 T2.

From an overview of the cited prior art it follows that the known solutions are each very specifically specialized for the respective application, ie the respective element to be assembled. On the one hand, this requires special components and, on the other hand, assembly personnel have to deal with a wide variety of devices. Another aspect of the prior art is that in many cases thermal insulation between the fastening base and the panel element to be fastened would be advantageous. This is of course particularly true for infrared heating panels, as the aim is not to heat the mounting surface, but rather to radiate as much heat as possible into the room.

The object of the invention is to create a fastening for panel elements to a fastening base, which can be used more universally and/or offers improved thermal insulation between the panel element to be fastened and the fastening base.

With regard to the holding device, the object is achieved by the features of claim 1, namely in that the holding plate is produced by solidifying a plastic mass, the plastic mass containing expanded glass and / or foam glass as a filling component.

The holding plate does not have to be in the form of a plate with a rectangular basic shape, although this is the case in preferred embodiments.

The holding plate can have a constant thickness and/or be flat. But neither is absolutely necessary.

In particularly preferred embodiments, a basic shape of the holding plate corresponds to a basic shape of the panel element held thereby. Protection is also desired for an arrangement with a holding device according to the invention and at least one, in particular according to the invention, mounting device, wherein the holding device, optionally together with a panel element, in particular an infrared heating panel, by means of the at least one mounting device through interaction of the bolt element with the at least one fastening element of the holding device on the one hand and with the holding section of the at least one mounting device on the other hand is attached to the mounting base.

With regard to the mounting device, the object is achieved by the features of claim 8, namely in that the mounting device has at least one mounting section that can be placed on the mounting base and at least one holding section, the at least one holding section being released from the mounting base when the at least one mounting section rests on the mounting base, and wherein the holding section has at least one fastening opening, which at least one fastening opening is opened laterally, so that a bolt element can be inserted laterally into the at least one fastening opening so that a head section of the bolt element lies between the fastening base and the at least one holding section.

The bolt element can preferably be a screw, although other designs are of course also conceivable, for example with a threaded rod together with a nut, which then forms the head section, or with a rivet.

By exposing the at least one holding section and the lateral opening of the at least one Fastening opening, the bolt element can be inserted in a particularly simple manner so that the head section of the same lies between the fastening base and the at least one holding section.

Through the lateral opening of the at least one fastening opening, the bolt element can be inserted into the at least one fastening opening, even if the mounting device is already mounted on the fastening base.

This means that the mounting device can be mounted very easily and the holding device can be attached to the mounting device particularly easily because the bolt element can be attached to at least one fastening element and then inserted into the at least one fastening opening like a hook.

Together with the holding device according to the invention, a particularly simple attachment of panel elements can be achieved.

In particularly preferred embodiments, the at least one fastening opening on the lateral opening has at least one elevation, preferably two elevations, preferably in the form of one or more (relatively small) thorns. These can prevent the bolt element from coming out laterally from the at least one fastening opening. In other words, such elevations can achieve a certain positive connection between the bolt element and the mounting device. The at least one elevation can preferably be arranged on a leading edge and/or corner of the lateral opening of the fastening opening.

The at least one elevation can be designed as a deep-drawn, raised structure if the mounting device is designed in the form of a sheet metal part.

It should be noted that lateral for the purposes of the invention can be understood as being substantially transverse to a longitudinal axis of the bolt element.

With regard to the manufacturing process, the task is solved by the features of claim 12, namely by

- a plastic mass is provided, the plastic mass containing expanded glass and/or foam glass as a filling component,

- a mold for a holding plate is provided,

- the plastic mass is filled into the mold and

- the holding plate is created by the plastic mass solidifying.

Preferably, it can be provided that at least one fastening element is at least partially introduced into the mold, the plastic mass surrounds and/or passes through the at least one fastening element when the plastic mass is filled into the mold, and the at least one fastening element by solidifying the plastic Mass is embedded in the holding plate.

Preferably, it can be provided that the holding device optionally passes together with a panel element, in particular an infrared heating panel, by means of at least one assembly device, in particular according to the invention Interaction of a bolt element with the at least one fastening element of the holding device on the one hand and with a holding section of the at least one mounting device on the other hand is fastened to the fastening base.

What was said above with regard to the geometry of the holding plate can of course also apply analogously to the shape, which can essentially be a geometric negative of the holding plate.

It cannot be ruled out that the holding plate will be reworked after the plastic mass has solidified, for example by grinding, milling, polishing and/or coloring. In this sense, the shape can only be “essentially” a geometric negative of the holding plate.

The mounting base can be, for example, walls or ceilings in the interior of buildings.

The mounting base can particularly preferably be flat.

Protection is also sought after for a set consisting of a holding device according to the invention and at least one mounting device according to the invention.

Protection is also sought after for the use of a holding device according to the invention and/or a mounting device according to the invention for mounting and/or fastening a panel element to a fastening base.

Advantageous developments of the invention are defined in the dependent claims. The plastic mass can contain a binder component.

In particularly preferred embodiments, the binder component ensures that the plastic mass is initially plastic and then becomes solid.

The binder component can contain a mineral binder.

At least one fastening element can be provided for fastening the holding plate to a fastening base, which is embedded in the holding plate by solidifying the plastic mass.

According to such preferred embodiments of the invention, the holding plate can fulfill a dual function. On the one hand, a simple way of holding the panel elements can be created by casting the at least one fastening element. On the other hand, the holding plate can at the same time offer an insulating effect, which is particularly true in preferred embodiments with expanded glass as a filler in the plastic mass.

The fact that the at least one fastening element is embedded in the holding plate can be understood to mean that the material of the holding plate surrounds and/or passes through the at least one fastening element in such a way that the at least one fastening element is thereby held in a force-fitting and/or form-fitting manner.

According to the invention, this embedding takes place by solidifying a plastic mass, particularly preferably with expanded glass as a filler for the plastic mass. The one that has become stuck Plastic mass then forms at least partially, preferably completely, the holding plate.

One aspect of particularly preferred embodiments of the invention could therefore be described by the fact that the at least one fastening element is cast into the holding plate.

The at least one fastening element may include a tubular element that is embedded in the holding plate.

In particularly preferred embodiments, the fastening element, preferably the tubular element, can be attached to the panel element before the plastic mass is introduced into the mold.

This can be done, for example, by an adhesive and/or screw connection.

It can be provided that the panel element is part of the mold used in the method according to the invention.

When introducing the plastic mass into the mold, it can particularly preferably be provided that the entire free space in the mold is filled by the plastic mass.

It can be provided that the plastic mass is compacted during and/or after being introduced into the mold, for example by shaking movements.

The at least one fastening element can contain a threaded element, in particular a blind rivet nut. To attach the holding plate to the mounting base, an external thread of the bolt element can be screwed into the threaded element.

Two nuts can sit on the external thread, with the head section of the bolt element being clamped onto the holding section of the mounting device by means of the nuts and/or the screwing of the bolt element to the fastening element being secured.

In particularly preferred embodiments it can be provided that

- the at least one fastening opening has at least one elevation on the lateral opening,

- the bolt element interacting with the mounting device has an external thread,

- Two nuts sitting on the external thread, the head section of the bolt element being clamped onto the holding section of the mounting device by means of the nuts and the screw connection of the bolt element to the fastening element being secured.

By fastening the holding device via a thread and two nuts, a backlash-free fastening can be achieved on the one hand, which on the other hand is particularly stable and secured against unwanted loosening or levering of the holding device from the mounting device because the elevations prevent the bolt element from emerging from the lateral opening of the fastening opening impede.

Alternatively or in addition to the mineral binder, a cement-based or synthetic resin binder can be used. Expanded glass has the particular advantage that it is usually made from previously used glass and is therefore particularly environmentally friendly.

Expanded glass and/or foam glass can also be particularly preferred in the context of the invention because it is particularly heat-resistant, has a high insulating value and is light, dimensionally stable, free of pollutants and durable.

The expanded glass can have a grain size of 1 mm to 10 mm, preferably 2 mm to 8 mm.

The expanded glass can have a thermal conductivity of 0.03 W/m K to 0.01 W/m K, preferably 0.07 W/m K to 0.09 W/m K.

The expanded glass can have a compressive strength of 0.5 N/mm ² to 1 N/mm ² , preferably 0.7 N/mm ² .

The holding plate 4 was produced by embedding the at least one fastening element 5 in the holding plate 4 by solidifying a plastic mass.

In this exemplary embodiment, the at least one fastening element 5 contains a tubular element 7, which was embedded in the holding plate 4 in this way.

In this exemplary embodiment, the at least one fastening element 5 contains a threaded element 8, here a blind rivet nut.

The embodiment of the holding device 1 shown here was manufactured by

- a plastic mass was provided,

- a mold for a holding plate 4 was provided,

- the fastening element 5 was inserted into the mold,

- the plastic mass was filled into the mold so that the plastic mass surrounds and passes through at least the fastening element 5, and

- The fastening element 5 was embedded in the holding plate 4 by the plastic mass solidifying. In the present exemplary embodiment, the plastic mass contains a binder component and a filling component.

Specifically, a mineral binder was used for the binder component and expanded glass was used as the filling component, which are sold under the Geocell brand.

In addition, the mounting device 2 for mounting the holding device 1 on the mounting base 6 can be seen in FIG.

The mounting device 2 of this exemplary embodiment has two mounting sections 9 which can be placed on the mounting base 6 and a holding section 10, the holding section 10 being released from the mounting base 6 when the at least one mounting section 9 rests on the mounting base 6 as shown.

For example, the mounting sections 9 and thus the mounting device 2 are mounted on the mounting base 6 via fastening screws 15.

The holding section 10 has a fastening opening 11, which is opened laterally, so that a bolt element 12 can be inserted laterally into the at least one fastening opening 11 so that a head section 13 of the bolt element 12 lies between the fastening base 6 and the at least one holding section 10.

With regard to the fastening opening 11, reference is also made to FIG. 2.

It can be seen that the mounting sections 9 and the holding section 10 are designed as a common bent sheet metal part. The holding device 1 is fastened to the fastening base 6 by means of the at least one mounting device 2 through interaction of the bolt element 12 with the at least one fastening element 5 of the holding device 1 on the one hand and with the holding section 10 of the at least one mounting device 2 on the other hand.
