Description

[0001] Holding device for a panel element

[0002] 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 surface and a manufacturing method for a holding device.

[0003] Devices for mounting panel elements are generally known in the prior art, for which reference can be made, for example, to DE 1960887 A1.

[0004] The use of expanded glass with infrared-based heating elements is also generally known; reference is made to DE 102013003155 A1.

[0005] Devices for mounting radiators are also known, for example, reference should be made to DE 60010565 T2.

[0006] A review of the cited prior art reveals that the known solutions are each highly specialized for the respective application, i.e., the specific element to be installed. This requires special components, and installation personnel must be familiar with a wide variety of equipment. Another aspect of the prior art is that, in many cases, thermal insulation between the mounting surface and the panel element to be installed would be advantageous. This is especially true for infrared heating panels, since the goal is not to heat the mounting surface, but rather to radiate as much heat as possible into the room.

[0007] The object of the invention is to provide a fastening for panel elements to a fastening surface which can be used more universally and / or offers improved thermal insulation between the panel element to be fastened and the fastening surface.

[0008] 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, wherein the plastic mass contains expanded glass and / or foam glass as a filling component.

[0009] 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.

[0010] The support plate can be of constant thickness and / or flat. However, neither is absolutely necessary.

[0011] 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 sought for an arrangement comprising a holding device according to the invention and at least one mounting device, in particular according to the invention, wherein the holding device, optionally together with a panel element, in particular an infrared heating panel, is fastened to the mounting surface by means of the at least one mounting device through the 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.

[0012] 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 which can be placed on the fastening base and at least one holding section, wherein the at least one holding section is free from the fastening base when the at least one mounting section rests on the fastening base, and wherein the holding section has at least one fastening opening which is laterally open such that a bolt element can be inserted laterally into the at least one fastening opening such that a head section of the bolt element lies between the fastening base and the at least one holding section.

[0013] 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.

[0014] 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 such that the head section thereof lies between the fastening surface and the at least one holding section.

[0015] 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 surface.

[0016] 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 the at least one fastening element and then inserted into the at least one fastening opening similar to a hook.

[0017] Together with the holding device according to the invention, a particularly simple fastening of panel elements can be achieved.

[0018] In particularly preferred embodiments, the at least one fastening opening has at least one elevation, preferably two elevations, preferably in the form of one or more (relatively small) spikes, on the lateral opening. These can prevent the bolt element from undesirably protruding laterally from the at least one fastening opening. In other words, such elevations can achieve a certain form-fitting 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.

[0019] The at least one elevation can be formed as a deep-drawn, raised structure if the mounting device is designed in the form of a sheet metal part.

[0020] It should be noted that lateral for the purposes of the invention can be understood as substantially transverse to a longitudinal axis of the bolt element.

[0021] With regard to the manufacturing process, the problem is solved by the features of claim 12, namely by

[0022] - a plastic mass is provided, wherein the plastic mass contains expanded glass and / or foam glass as a filling component,

[0023] - a mold for a holding plate is provided,

[0024] - the plastic mass is filled into the mold and

[0025] - the holding plate is created by the solidification of the plastic mass.

[0026] 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 penetrates the at least one fastening element when the plastic mass is filled into the mold, and the at least one fastening element is embedded in the holding plate by the plastic mass solidifying.

[0027] Preferably, it can be provided that the holding device is optionally fastened to the fastening surface together with a panel element, in particular an infrared heating panel, by means of at least one mounting device, in particular according to the invention, by 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.

[0028] What has been 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.

[0029] It is not excluded that the retaining plate may be further processed after the plastic mass has solidified, for example, by grinding, milling, polishing, and / or coloring. In this sense, the mold can only be "essentially" a geometric negative of the retaining plate.

[0030] The mounting surface can, for example, be walls or ceilings inside buildings.

[0031] The mounting surface can preferably be flat.

[0032] Protection is also sought for a set comprising a holding device according to the invention and at least one mounting device according to the invention.

[0033] Protection is also sought 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 substrate.

[0034] Advantageous developments of the invention are defined in the dependent claims. The plastic mass may contain a binder component.

[0035] In particularly preferred embodiments, the binder component ensures that the plastic mass is initially plastic and then becomes solid.

[0036] The binder component may contain a mineral binder.

[0037] At least one fastening element for fastening the holding plate to a fastening substrate can be provided, which fastening element is embedded in the holding plate by solidifying the plastic mass.

[0038] According to such preferred embodiments of the invention, the retaining plate can fulfill a dual function. On the one hand, by encapsulating the at least one fastening element, a simple means of holding the panel elements can be created. On the other hand, the retaining plate can simultaneously provide an insulating effect, which is particularly true in preferred embodiments using expanded glass as a filler in the plastic mass.

[0039] 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 penetrates 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.

[0040] According to the invention, this embedding occurs by solidifying a plastic mass, particularly preferably with expanded glass as a filler for the plastic mass. The solidified plastic mass then forms at least partially, preferably completely, the retaining plate.

[0041] One aspect of particularly preferred embodiments of the invention could therefore be described as the fact that the at least one fastening element is cast into the holding plate.

[0042] The at least one fastening element may include a tubular element embedded in the retaining plate.

[0043] In particularly preferred embodiments, the fastening element, preferably the tubular element, can be fastened to the panel element before the plastic mass is introduced into the mold.

[0044] This can be done, for example, by means of an adhesive and / or screw connection.

[0045] It can be provided that the panel element is part of the mold used in the method according to the invention.

[0046] When introducing the plastic mass into the mold, it can be particularly preferred that the entire free space in the mold is filled by the plastic mass.

[0047] It may be provided that the plastic mass is compacted during and / or after introduction into the mold, for example by vibrating movements.

[0048] The at least one fastening element may include a threaded element, in particular a blind rivet nut. To secure the retaining plate to the mounting surface, an external thread of the bolt element may be screwed into the threaded element.

[0049] Two nuts can be seated on the external thread, whereby the head section of the bolt element can be clamped onto the holding section of the mounting device by means of the nuts and / or the screw connection of the bolt element to the fastening element can be secured.

[0050] In particularly preferred embodiments, it may be provided that

[0051] - the at least one fastening opening has at least one elevation on the lateral opening,

[0052] - the bolt element cooperating with the mounting device has an external thread,

[0053] - two nuts sitting on the external thread, whereby by means of the nuts the head section of the bolt element can be clamped onto the holding section of the mounting device and the screw connection of the bolt element with the fastening element can be secured.

[0054] By fastening the holding device via a thread and two nuts, on the one hand a play-free fastening can be achieved, 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.

[0055] Alternatively, or in addition to the mineral binder, a cement-based or synthetic resin binder can be used. Expanded glass has the particular advantage of being made from pre-used glass and is therefore particularly environmentally friendly.

[0056] Expanded glass and / or foam glass may also be particularly preferred within the scope of the invention because it is particularly heat-resistant, has a high insulating value and is light, dimensionally stable, free from harmful substances and durable.

[0057] The expanded glass can have a grain size of 1 mm to 10 mm, preferably 2 mm to 8 mm.

[0058] The expanded glass may have a thermal conductivity of 0.03 W / m K to 0.01 W / m K, preferably of 0.07 W / m K to 0.09 W / m K.

[0059] The expanded glass can have a compressive strength of 0.5 N / mm 2 up to 1 N / mm 2 preferably 0.7 N / mm 2 , have.

[0060] Further advantages and details of the invention are apparent from the figures and the accompanying description. These show:

[0062] Fig. 2 is a plan view of an embodiment of a mounting device according to the invention,

[0063] Fig. 3 a schematic rear view of the

[0064] Embodiment according to Fig. 1 and

[0065] Fig. 4 is a schematic front view of the

[0066] Embodiment according to Fig. 1. In Fig. 1, a holding device 1 for a panel element 3, in this embodiment an infrared heating panel, is shown, which has a holding plate 4, to which the panel element 3 can be fastened, and at least one fastening element 5 for fastening the holding plate 4 to a fastening base 6.

[0067] The holding plate 4 was manufactured by embedding the at least one fastening element 5 into the holding plate 4 by solidifying a plastic mass.

[0068] In this embodiment, the at least one fastening element 5 includes a tubular element 7 which has been embedded in the holding plate 4 in this way.

[0069] In this embodiment, the at least one fastening element 5 includes a threaded element 8, here a blind rivet nut.

[0070] The embodiment of the holding device 1 shown here was manufactured by

[0071] - a plastic mass was provided,

[0072] - a mold for a holding plate 4 has been provided,

[0073] - the fastening element 5 has been inserted into the mould,

[0074] - the plastic mass has been filled into the mold so that the plastic mass surrounds and penetrates at least the fastening element 5, and

[0075] - the fastening element 5 was embedded in the retaining plate 4 by the solidification of the plastic mass. In the present embodiment, the plastic mass contains a binder component and a filler component.

[0076] Specifically, a mineral binder was used for the binder component and expanded glass was used as the filler component, which are sold under the brand name Geocell.

[0077] In addition, Fig. 1 shows the mounting device 2 for mounting the holding device 1 on the fastening surface 6.

[0078] The mounting device 2 of this embodiment has two mounting sections 9 that can be placed on the fastening base 6 and a holding section 10, wherein the holding section 10 is free from the fastening base 6 when the at least one mounting section 9 rests on the fastening base 6 as shown.

[0079] For example, the mounting sections 9 and thus the mounting device 2 are mounted on the mounting base 6 using fastening screws 15.

[0080] The holding section 10 has a fastening opening 11 which is laterally open so that a bolt element 12 can be inserted laterally into the at least one fastening opening 11 such that a head section 13 of the bolt element 12 lies between the fastening base 6 and the at least one holding section 10.

[0081] With regard to the fastening opening 11, reference is also made to Fig. 2.

[0082] It can be seen that the mounting sections 9 and the holding section 10 are formed as a common bent sheet metal part. The holding device 1 is fastened to the mounting base 6 by means of the at least one mounting device 2 through the 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.

[0083] An external thread is provided on the bolt element 12 (here a screw), which interacts with the internal thread of the threaded element 8.

[0084] Nuts 14 are provided, which also sit on the external thread of the bolt element 12 and can be used to clamp the head section 13 of the bolt element 12 onto the holding section 10 of the mounting device 2 (upper nut 14 in Fig. 1) and to secure the screw connection of the bolt element 12 to the fastening element 5 (similar to a lock nut, lower nut 14 in Fig. 1).

[0085] The holding plate 4 can thus serve as a support or holder for the panel elements 3, for which reference is made to Fig. 4.

[0086] In the present embodiment, the tubular element 7 was glued to the panel element 3 before the plastic compound was introduced into the mold. This means that the tubular element 7 is first glued in place and then bonded to the plastic compound. It is glued to tiles or, if space is limited, to the heating panel.

[0087] The panel element 3 was part of the mold used in the process according to the invention. An additional cover plate or the like is therefore not required. Clamps or additional screws can be used alternatively or additionally to attach the panel elements 3 to the support plate 4.

[0088] Fig. 2 shows an embodiment of a mounting device 2 according to the invention. The lateral opening 11, which is located between two elevations 16, can be seen.

[0089] The connecting lines still visible in the area of ​​the fastening opening 11 symbolize the rear boundary of the fastening opening in the area of ​​the holding section 10.

[0090] The elevations 16 are arranged at a leading corner of the lateral opening of the fastening opening 11.

[0091] The elevations are formed as a deep-drawn, raised structure of the sheet metal part forming the mounting device 2.

[0092] The bolt element 12 can be inserted into the fastening opening 11 through the laterally opened fastening opening 11, even if the mounting device 2 is already mounted on the fastening base 6.

[0093] In summary, the present embodiment provides that

[0094] - the at least one fastening opening 11 has at least one elevation 16 on the lateral opening,

[0095] - the bolt element 12 cooperating with the mounting device 2 has an external thread,

[0096] - two nuts 14 sitting on the external thread, whereby by means of the nuts 14 the head section 13 of the bolt element 12 can be clamped onto the holding section 10 of the mounting device 2 and the screw connection of the bolt element 12 to the fastening element 5 can be secured.

[0097] Fig. 3 shows schematically a rear view of an embodiment of an arrangement according to the invention, wherein four mounting devices 2 are provided in order to fasten a holding device 1 to the fastening surface.

[0098] In the assembly device 2 in Fig. 3, bottom left, the plane along which the section from Fig. 1 is drawn is also shown.

[0099] Fig. 4 shows the embodiment according to Fig. 3 in a front view after the panel elements 3 have been attached to the holding plate 4.

[0100] In this embodiment, the panel elements 3 are provided in two layers. In a first layer, an infrared heating panel is mounted on the support plate 4. In this embodiment, the infrared heating panel completely covers the support plate 4.

[0101] In this example, ceramic tiles are arranged in a second, overlying layer.
