Description

The present invention relates to a holding device for holding at least one functional group, wherein the holding device comprises at least one clamping device for reversible fastening in and / or on at least one shaft section, wherein the clamping device has at least one first leg element with a first contact section and at least one second leg element with at least one second contact section, wherein the first and the second leg element are operatively connected via at least one connecting section. The present invention also relates to a holding device system having at least one such holding device.A plurality of holding devices are known which at least temporarily hold at least one functional unit, such as a lamp, a tool, a cable and / or a hose, in particular during assembly, repair and / or maintenance work. Thus, for example, when performing assembly and / or maintenance work, in particular in dark and / or insufficiently illuminated rooms with only low natural incidence of light, such as e.g. shafts and / or channels, it is regularly necessary for a room section to be illuminated or even substantially illuminated in order to enable a technician to reliably and in particular quickly and safely carry through the work.It is usually expedient here for such holding devices to be able to be arranged or fastened reversibly in the rooms and / or room sections, with the result that they are removed again, in particular after performance and / or completion of the work, and are able to be arranged / fastened, for example, at another location. It is also regularly desirable and advantageous that different functional units can be held simultaneously by the holding device and / or that replacement of the functional groups is possible in order to be able to make tools available flexibly for example for assembly and / or maintenance work.Such known holding devices function largely expediently and reliably.However, the disadvantage of known holding devices is that they are often not space-saving in design and / or can be arranged in a space-saving manner, in particular reversibly and / or reliably. Compliance with work protection regulations is also problematic in particular at and / or in particularly confined space sections. Thus, fastening of known holding devices in narrow or even very narrow spaces such as, for example, shafts, channels and / or the like is often possible only with a partly considerable outlay or even not at all. Known holding devices also regularly prevent, disturb or prevent installation and / or maintenance work from being carried out in and / or on rooms which are confined at least in sections.It is therefore the object of the present invention to provide a holding device which can be fastened quickly, in particular in confined spaces such as shafts, and which reliably holds at least one functional group.This object is achieved by a holding device having the features of claim 1 and a holding device system having the features of claim 25. Further advantages and features of the invention are evident from the exemplary embodiments.The holding device according to the invention for holding at least one functional group comprises at least one clamping device for reversible fastening in and / or on at least one shaft section, wherein the clamping device has at least one first leg element with a first contact section and at least one second leg element with at least one second contact section. The first and the second leg element are operatively connected via at least one connecting section. Furthermore, the first and the second contact section essentially face each other and are displaceable relative to each other at least in sections along a longitudinal extension of the connecting section. At least one holding element for holding the at least one functional group is included.The holding device preferably serves for holding and / or arranging at least one functional group in at least one shaft and / or channel, in particular in an opening and / or entry region of a shaft and / or channel. Depending on the task and design, the holding device can also hold the at least one functional group in other, in particular confined, rooms or even outdoors.In expedient refinements, the holding element is suitable and designed to reversibly receive and / or hold the functional group, such that, depending on the situation and / or need, the functional group can be removed, removed, exchanged and / or exchanged from the holding device.In advantageous refinements, the holding device can be fastened reversibly by means of the clamping device in and / or on a shaft and / or channel section, in particular in an opening and / or entry region of a shaft and / or channel. In this case, an opening and / or entry region of a shaft and / or channel preferably also comprises a section which is arranged outside the shaft and / or channel in the immediate vicinity thereof. In particular, a holding device, in particular a clamping device, fastened in and / or on a shaft section can be arranged at least in sections outside the shaft. Depending on the task and configuration, the holding device can also be reversibly fastened by means of the clamping device to receiving sections, such as wall, ceiling and / or wall sections, in particular wall, ceiling and / or wall projections.In expedient refinements, the first and the second limb element, in particular the first and the second bearing section, can be arranged and / or are arranged spaced apart from one another at least in sections along the longitudinal extent of the connecting section.In expedient refinements, the first leg element provides the first bearing section and the second leg element provides the second bearing section. Depending on the task and configuration, the first and / or the second contact section can also be present as a separate module, for example, which in particular is surrounded by the first and / or the second leg element and / or is received in sections.In advantageous refinements, the first and the second contact section are suitable and configured for being arranged at least in sections on a shaft section and / or receiving section, in particular in such a way that the first and the second contact section are in planar contact with the shaft section and / or the receiving section.In expedient refinements, the first and the second contact section are each designed at least as a clamping section and / or provide in each case at least one clamping section, by means of which a force, preferably clamping force, can be applied to the shaft section at least temporarily, in particular in a contact position.Preferably, the first and the second contact section, in particular the first and the second limb element, can be displaced with respect to one another and / or with respect to one another. Preferably, at least the first and / or the second contact section is displaceable relative to the other contact section. Preferably, at least the first and / or the second leg element is displaceable relative to the other leg element.In advantageous refinements, the connecting section is substantially rectilinear, such that the longitudinal extent of the connecting section extends a longitudinal axis of the connecting section. Depending on the task and design, the connecting section can also be curved and / or curved or have another suitable shape.Preferably, the first and / or the second leg element, in particular the first and / or the second contact section, is designed to be so strong, stiff and / or flexurally rigid that a clamping force can be applied between the first and / or the second contact section.Preferably, the first and / or the second leg element, in particular the first and / or the second contact section, is formed at least in sections from a metallic material.

In particular, the clamping device can hereby enclose a shaft section in sections, so that a fastening of the holding device to a shaft section is even more secure and reliable.Due to the fact that the first and the second contact section are displaceable relative to one another along a longitudinal extension of the connecting section, a distance between the first and the second contact section can be adjusted in a particularly flexible and / or user-friendly manner, so that the holding device according to the invention can be received and / or reversibly fastened on, in particular differently shaped and / or dimensioned, shaft sections. The holding device according to the invention enables in particular a rapid fastening and / or loosening of the clamping device, in particular with only a few handles and / or even a reversible fastening and / or loosening carried out with substantially one hand.The holding device according to the invention can also be arranged on shaft sections and / or can be reversibly fastened in such a way that the holding device substantially does not interfere with, obstruct or even prevent the performance of installation, assembly and / or maintenance work.
