Description

The invention relates to a base structure of a tent for arrangement on substantially flat ground, comprising a plurality of floor supports, which are oriented horizontally and parallel to each other, and have open accommodation grooves facing each other for inserting bottom segments, a plurality of longitudinal supports, which are arranged horizontally, in parallel to each other, and orthogonal in relation to the floor supports, are connected to two adjacent floor supports, and furthermore having at least one ballast body. The invention further relates to a tent having a tent base structure with floor supports for receiving bottom segments and longitudinal supports oriented orthogonally thereto as well as having a tent structure with vertically oriented tent pillars.

Generic tents are used in those places where a protected space is to be provided in the short-term and/or temporarily, for example, as storage or sales area or also as exhibition area.

Such generic tents in some cases have the size of a large building and can have a base area of several hundred m2. Their height is frequently four or more metres. Accordingly, in generic tents, measures must be taken to secure the tent sufficiently against wind forces acting on the tent so that a lifting of the tent and/or a displacement of the tent under the wind pressure is avoided. The simplest way of doing this consists in fixing the tent on the ground by means of ground nails, wherein this is not always possible or not always possible to a sufficient extent, for example, if the tent is erected on a fixed base or if there is a risk of supply lines being damaged by ground nails.

In those places where it is not possible to sufficiently fix the tent on the ground by means of such connecting means such as ground nails, a sufficient ballasting of the tent with ballast bodies must be provided. For this purpose, for example it is only possible to ballast the base structure of the tent on its outer side next to the tent, wherein this is seen as disadvantageous since such ballastings are accessible from outside and therefore for example are associated with a risk of tripping. It is also possible to arrange ballast bodies inside the erected tent. As a result however, the usable base area of the tent interior is reduced. In addition, for aesthetic reasons such a ballasting inside the tent is also not desirable depending on the intended application purpose.

Another solution is obtained from DE 198 09 733 B4. This consists in providing the base structure of the tent directly with a ballasting so that the corresponding ballast bodies are arranged underneath the bottom segments of the tent. For this purpose it is provided to provide, parallel to the outside longitudinal supports, so-called ballast supports and place the ballast bodies so that they overlap the outside longitudinal supports and the ballast supports. Figure 1 shows a design which approximately corresponds to the design of DE 198 09 733 B4, wherein the ballast bodies are shown by dashed lines.

It is seen as a disadvantage of this solution that the force flow from the tent pillars to the ballastings takes place through a plurality of components and in particular through a plurality of component transitions which therefore seem to make a failure of this solution possible. In particular, this is the case when the floor support, designated in DE 198 09 733 B4 as rail beam, is configured as an aluminium part and therefore has a reduced stiffness compared to steel. It is furthermore seen as disadvantageous that in this design the ballastings for the case that a high ballasting is required are in some cases very remote from the force-introducing tent pillars so that their effect is reduced and there is the risk that the longitudinal support and/or the ballast support become deformed to a considerable extent when the tent is held against the wind in the vertical and in the horizontal by the ballasting. This problem is further exacerbated by the fact that the scope for arrangement of the ballast bodies is limited by diagonal struts frequently provided in the underside of the bottom segments so that the ballast bodies spanning the longitudinal support and the ballast support cannot be arranged in an uninterrupted row in the vicinity of the tent pillars, as illustrated in Fig. 1. W02004/072394A2 discloses a tent structure having the features of the preamble of claim 1.

Object and solution

It is the object of the invention to further develop a generic tent and a generic base structure of a tent so that this allows a high degree of ballasting with high reliability. In this case, it is in particular intended to achieve that components used hitherto in the area of the base structure of a tent, such as those deduced from Figure 1, can still be used in an unchanged or largely unchanged manner.

According to the invention, this object is solved in that the at least one ballast body is arranged in such a manner that its weight force, without a longitudinal support interposed, acts on a floor support loaded with the ballast body. A base structure of a tent according to the invention has floor supports parallel to one another which have accommodation grooves for inserting the bottom segments. These floor supports are not only interconnected by the bottom segments but also by the longitudinal supports aligned orthogonally to them, which are preferably arranged underneath the floor supports. The floor supports, which are usually also designated as rail beams, are parts which can no longer be further dismantled when erecting and dismantling tents as intended, which are preferably manufactured as integral profiles, in particular made of aluminium or an aluminium alloy. These floor supports serve in particular as supports of the bottom segments, which can be configured for example as wooden panels or as wooden laths joined together with diagonal or transverse struts. Furthermore, the floor supports, at least when a base structure of a tent according to the invention, is not fixed to the ground with ground nails, are used to receive the horizontally and vertically upwardly directed forces acting on the vertical tent pillars, which are caused by the wind acting on the tent.

The at least one ballast body is arranged in the region of the base structure, i.e., underneath the bottom segments. In this case, it is provided that the introduction of force introduced by the vertical tent pillars into the floor support acts on the at least one ballast body avoiding the longitudinal support and therefore in particular avoiding the connection between longitudinal support and floor support. It is thereby avoided that the force caused by the wind and acting on the tent pillar must be guided via the connection between the floor support and the longitudinal support which is possibly not sufficient for this. The risk of tearing out of the connecting means provided at this connection is thus reduced.

The weight force of the at least one ballast body or the preferably provided plurality of ballast bodies can act on the floor support avoiding the longitudinal support in two ways. On the one hand, at least a part of the weight force of the ballast body acts against a vertical upwardly directed force which acts from the tent pillar on the floor support and from this on the ballast body. On the other hand, that part of the weight force which does not counteract any force caused by the wind and acting vertically upwards on the tent pillar and therefore the floor support 10, acts as weight force indirectly or directly acting on the ground and thus prevents the horizontally acting force of the wind from displacing the tent. The ballast body or several of a plurality of ballast bodies can thus be arranged so that their weight force in a rest state rests directly on the ground, so that they in particular act against any displacement of the tent. Preferably however they are attached to the floor support in such a manner that when there is a vertically upwardly acting force on the tent pillars, they are able to counteract this force without the tent pillar needing to be raised by the wind by more than a few millimetres for this purpose.

Naturally, all the parts of a tent base structure also act as ballast even if this is not their intended purpose. Ballast body in the sense of the invention is understood as such an inherently rigid body which is used for the ballasting as intended. Ballast bodies according to the invention are preferably characterized in that they are provided additionally to those components of the base structure which impart to the base structure its inner stability and themselves do not take on any function to produce this innate stability. These are preferably bodies having a large mass, preferably of at least 20 kg. When using a multiplicity of structurally identical small ballast bodies to load the same floor support, these jointly have a mass of at least 20 kg, preferably of at least 40 kg. The ballast bodies are preferably made of metal, in particular of steel. In order to achieve a high ballasting effect with low volume, the ballast bodies have an essentially cuboid-shaped design, wherein this is understood as a design in which the ballast body fills at least 70 %, preferably at least 80 %, of the volume of an imaginary smallest cuboid, where the ballast body just fits in completely.

The present invention is explained subsequently mostly with reference to a plurality of ballast bodies since it is preferred that a plurality of ballast bodies are provided jointly for the ballasting. Insofar as nothing different is obtained from the conceptual context however, a design with only one ballast body having correspondingly higher mass is also possible.

According to the invention, the ballast bodies always act exclusively on the floor support in such a manner that it can only receive horizontal forces and even when the floor support is lifted by a few cm, is not lifted with it and thus also does not have any ballasting effect in the vertical direction.

According to the invention is the design in which the ballast bodies are configured and/or arranged in such a manner that their weight force, at least in the case where the floor support is raised by at most 2 cm in the area of the introduction of force, acts on the floor support with its weight force at least partially or preferably completely in the vertical direction so that only a portion of its weight force acts directly on the ground avoiding the floor support. A design is deemed to be advantageous in which for accommodating the at least one ballast body, a holding device is provided and associated with the loaded floor support, which holding device preferably is configured as a profiled section extending in the main extension direction of the loaded floor support, and in which furthermore the at least one ballast body is configured as a ballast body of a first type and has a hanging device on a proximal side, by means of which hanging device the ballast body can be mounted in the holding device such that a distal side of the ballast body facing away from the hanging device is not in physical contact with the ground.

Since the distal side of the ballast body is not in contact with the ground, the weight force of the ballast body acts completely on the hanging device. The ballast body configured according to this further development has on one side, the proximal side, the said hanging device which is mounted in the holding device. Since the predominant part (>90 %) of the mass of the ballast body is provided on the distal side of the hanging device, the ballast body preferably has a support surface which is pressed against the holding device as a result of the mass moment of the ballast body. In order that no restrictions with regard to the arrangement of the ballast body is given by the bottom segments, the ballast bodies are preferably configured in such a manner that in the mounted state of the ballast bodies, an upwardly terminating upper side is arranged in the vertical direction underneath struts provided on the underside of the bottom segments.

The holding device is preferably provided as a profiled section extending parallel to the floor support and can serve to accommodate a plurality of structurally identical ballast bodies so that this then comparatively light ballast body can then be handled simply and by adapting the number of ballast bodies, the total ballast mass can be specifically adjusted.

It is particularly preferred if the ballast body of the first type is rod-shaped or plateshaped, and the hanging device of the ballast body and the holding device are configured and arranged such that the ballast body of the first type, in the mounted condition, is oriented essentially horizontally.

It is considered to be a rod-shaped configuration of the ballast body if the extension of the ballast body in two dimensions is in each case a maximum of a third of the extension in the third dimension. The ballast body is considered to be plateshaped if its extension in one dimension is a maximum of one third of the extension in the two other dimensions. A substantially horizontal alignment is considered to be an alignment which deviates by a maximum of 20° with respect to imaginary horizontal and flat ground.

The design with a rod-shaped or a plate-shaped ballast body allows a particularly good utilization of space. The ballast body mounted on one side extends in this case under the floor segments and efficiently uses the space provided there. The rod-shaped design is aimed in particular at the use of a plurality of ballast bodies which can be mounted parallel to one another in the holding device and thus enable a precise adaptation of the total ballast mass.

It is particularly advantageous if the loaded floor support is associated with two holding devices each for respectively accommodating at least one ballast body of the first type, wherein the holding devices are arranged such that the at least two ballast bodies of the first type, in the mounted condition, are arranged on opposite sides of the loaded floor support. In this arrangement, the mounted ballast bodies are thus oriented such that their distal ends point away from one another in each case. The design with two holding devices on the one hand allows a higher loading and on the other hand, an at least largely symmetrical loading of the floor support so that the torsional loading on the floor support can be kept small.

In principle, it is possible to provide devices for attachment of the ballast body directly integrally or otherwise detachably on the floor support. However, it is preferable if a ballast support is provided and is separate from the loaded floor support, which ballast support is configured for being fixed to a loaded floor support and is provided for accommodating and/or for hanging of the at least one ballast body. The ballast support can, according to the type described above, be fastened on the floor support in such a manner that it is connected to the floor support conducting force merely with a view to horizontally acting forces. Preferably however it is connected so that it can also counteract vertically acting forces on the floor support caused by the wind.

In this case, the ballast support need not be attached directly to the floor support but intermediate elements such as bolts, screws or intermediate plates can also be provided, in particular to bring about a spacing between the ballast support and the floor support. As a result of the separate design and the freedom of choice thereby given with regard to the use of the ballast support, it is possible to provide this or dispense with this depending on the application purpose. In particular, it is advantageous in the design as a separately configured ballast support that previously used floor supports can be re-used almost unchanged. Thus, in a preferred design, it is sufficient to provide the floor support with holes into which bolts are inserted which support the ballast support.

The said ballast support is configured in a further development in such a manner that the at least one holding device for the ballast body of the first type is provided on the ballast support. Particularly preferred is a design in which the ballast body has a profile oriented in the main extension direction of the floor support. This allows a very simple and cost-effective manufacture. In this case, a particular advantage is achieved if this profile is configured as a U-profile which provides two opposite holding devices in the manner described above as a result of its two parallel legs. In particular, this use of a U-profile is a very cost-effective possibility for configuring the ballast carrier. The profile, in particular the U-profile, hangs preferably directly under the floor support and extends parallel to this.

For direct ballasting of the floor support, it is possible to insert a ballast body directly in the floor support preferably configured as a hollow profile. It is of particular advantage, however, if alternatively or additionally, the ballast support separate from the floor support has an accommodation cavity and within this accommodation cavity a ballast body of a second type is provided. In this case, the said accommodation cavity can be achieved effectively and simply by using a U profile as a ballast support. The accommodation cavity offers the possibility of attaching a ballast body of the second type, without this needing to adopt a particularly characterized position which needs to be maintained precisely or needing to be coupled non-positively to other parts of the base structure. It is sufficient to insert the ballast body of the second type in the said accommodation space.

As already explained, the ballast body acting on the floor support serves primarily to receive upwardly directed forces which are caused by wind and act on vertically oriented tent pillars. For this purpose is provided on the floor support directly or indirectly preferably a fixing device for attaching the usually at least two-metre high tent pillars. This can be provided integrally on the floor support but preferably is connected to the floor support by means of one or more intermediate elements, in particular an intermediate element engaging in a hollow profile of the floor support. Preferably the force input portion of the floor support at which the at least one ballast body acts on this is provided on the floor support no more than 80 cm, in particular no more than 60 cm, away from that of the fixing device so that the introduction of force through the floor support is only accomplished over a comparatively short section. The force input portion can, for example, be formed by holes in the floor support on which the ballast support is suspended.

In particular, if the floor support has no high intrinsic stiffness, for example, because it is made of aluminium and/or is fabricated as a comparatively thin-walled profile, it is advantageous if a stabilizing element separate from the floor support is provided, which element extends from the fixing device up to the said force input portion of the floor support, on which the weight force of the at least one ballast body is acting on the floor support.

This stabilizing element thus has the result that only a part of the force input of the force acting upwards on the tent pillar between the tent pillar and the ballast body is accomplished through the floor support and another part is accomplished through the stabilizing element. In this case, the fixing device can be provided for attachment of the vertical tent support or a part thereof directly on this stabilizing element, wherein “directly” in this context means that the force input is accomplished at least partially avoiding the floor support itself. The stabilizing element can in order to have a ballasting effect itself, be configured with a high mass (>10 kg, preferably >20 kg) and optionally also extend from the fixing device as far as beyond the force input portion of the ballasting. A particular advantage is achieved if the stabilizing element is configured to be inserted into a cavity in the main extension direction of said floor support. For this purpose it has a preferably elongate, rod-shaped shape. The accommodation chamber into which the stabilizing element is inserted according to this further development is preferably an accommodation chamber arranged underneath the accommodation grooves.

The invention further relates to a generic tent which has a tent base structure of the type described above.

Brief description of the drawings

Further features and aspects of the invention are obtained, apart from the claims, from the following description of a preferred exemplary embodiment of the invention which is explained with reference to the figures. In the figures:

Fig. 1 shows the configuration of a tent base structure according to the prior art and

Figs. 2 to 4 show a first design of a tent base structure according to the invention.

Detailed description of the exemplary embodiments

Fig. 1 shows an already known structure of a tent base structure. This tent base structure comprises floor supports 10 and longitudinal supports 20, 26, wherein the longitudinal supports 20, 26 are oriented orthogonally to the single floor support 10 shown in Fig. 1 and fulfil the function both of supporting the bottom segments 30 and also the floor supports 10 and of supporting and interconnecting the mutually adjacent floor supports 10. The floor support 10 itself is configured as a two-chamber hollow profile and has accommodation grooves 12a, 12b on opposite sides, which serve to accommodate bottom segments 30. These bottom segments 30 which are each inserted in the accommodation grooves 12a, 12b of two adjacent floor supports 10 consist of individual laths which are joined together by means of transverse and diagonal struts 32a, 32b to form bottom segments 30.

The tent base structure rests by means of supporting flanges 22 of the external longitudinal supports 20 and supporting flanges 42 on so-called baseplates 40 on the ground 2. These base plates 40 are inserted in a manner not shown in detail in Fig. 1 on the front side into the floor supports 10 configured as hollow profiles. The connection between the longitudinal supports 20, 26 and the floor supports 10 is accomplished via bolts 24, 28 attached to the longitudinal supports 20, 26 and shown by the dotted lines in the figure, onto which the floor support 10 is pushed horizontally.

The baseplate 40 provides a fixing device 44 for attachment of a tent pillar not shown in Fig. 1 a. This fixing device 44 which is formed by a fork flange with holes for a retaining bolt forms the region in which the forces acting on the tent in particular due to wind are introduced into the base structure shown in Fig. 1. In this case, there is a particular problem with regard to the forces acting upwards in the direction of the arrow 4, which threaten to lift the tent from the ground.

If the ground condition is suitable for this, holes 22a, 42a in the supporting flanges 22, 42 are used for the attachment of ground nails. Forces acting on the tent pillar in the direction of the arrow 4 are therefore at least for the most part diverted into the ground by the baseplate 40 and avoiding the floor support 10 and the longitudinal supports 20, 26. However, this possibility is not always given, for example not if the tent is erected on an asphalt surface or other type of solid ground or the use of ground nails is not possible or not permitted for other reasons.

According to the prior art, in such a case ballast bodies 50 shown by the dashed lines are used instead, which span the exterior longitudinal support 20 and the interior longitudinal support 26 which acts as a ballast support and which hold the tent on the ground due to their mass. A problem here however is that the forces introduced via the tent pillar into the base plate 40 and from these into the floor support 10 must be introduced via holes 10a in the floor support 10 and the bolts 24, 28 inserted into these holes 10a, 10b must be introduced into the longitudinal supports since the ballast bodies 50 rest on these. In strong wind there is there fore a risk of failure at the bolts 24, 28, at the floor support 10 and/or at the longitudinal support 20. Furthermore, as a result of the arrangement of the struts 32a, 32b there is only a limited freedom with regard to the positioning of the ballast bodies 50 so that these optionally must be arranged comparatively far removed from the tent pillar 6 and the fixing device 44.

Fig. 2 firstly shows a design according to the invention in an overview diagram. The tent shown also has a base structure with floor supports 10 parallel to one another and longitudinal supports 20, 26 orthogonal thereto as well as with transverse supports 29 parallel to the floor supports 10. Bottom segments 30 extend between the floor supports 10, which bottom segments are inserted into the accommodation grooves 12a, 12b of the floor supports 10.

Arranged above the base structure is the tent superstructure which is supported by tent pillars 6 which are fixed in a manner explained in detail hereinafter on the base structure.

Fig. 3 shows in an enlarged view a region characterized by “A” in Fig. 2. This is a connecting region on which a tent pillar 6, a floor support 10 as well as two longitudinal supports 20 are joined together. For illustration the main components of Fig. 3 with the exception of the longitudinal supports 20 are shown in an exploded view in Fig. 4.

In agreement with the design according to the prior art, the components shown in Figs. 3 and 4 comprise a floor support 10, which is manufactured as a two-chamber hollow profile of aluminium, which has the already described accommodation grooves 12a, 12b for receiving the bottom segments 30 at the height of an upper chamber 14a and which has a lower chamber 14b forming the larger part of the cross-sectional area underneath the upper chamber 12a. Transversely to the main extension direction of the floor support 10, holes 10a, 10b are introduced therein, wherein the holes 10a serve to receive the bolts 24 of the longitudinal support 20 in the manner already described.

Also in agreement with the design according to the prior art, a baseplate 40 is provided which comprises the fixing device 44 for attachment of the tent pillar 6. This baseplate 40, which in the assembled state is arranged on the front side of the floor support 10, has an extension 46 a few centimetres in length, which is provided for insertion into the upper chamber 14a of the floor support 10.

In addition to the components already known from the design according to Fig. 1, the following components are provided. A stabilizing element 60 is provided for insertion into the lower chamber 14b. A ballast support 70 is provided for hanging on the floor support 10. Furthermore, rod-shaped ballast bodies 80 of a first type are provided for hanging onto the ballast support 70 and a bar-shaped ballast body 88 of a second type is provided for insertion into the ballast support 70.

The cooperation of these components is explained with reference in particular to Fig. 3. The stabilizing element 60 which itself has a high mass of about 40 kg, is inserted into the lower chamber 14b until only a fixing device 62 with holes for a bolt 64 projects beyond the end of the floor support 10. Fastened to this fixing device 62 by means of the bolt 64 is a supporting member 68 which is dimensioned and oriented so that its underside 68a is in physical contact or almost in physical contact with the upper side of the supporting flange 42 of the baseplate 40. By this means, a particularly advantageous input of force from the tent pillar 6 into the floor support 10 and the stabilizing element 60 is achieved since the force no longer needs to be input solely via the extension 46. In addition, it is effectively prevented that in the case of horizontal forces caused by wind, the baseplate 40 can be at a distance from the floor support 10.

The ballast support 70 has an upwardly open U profile 72 which is stabilized by means of transverse struts 74. It is suspended on the floor support 10 using intermediate plates 76 and fixing bolts 78 inserted into the holes 10b of the floor support 10. The bolts 78 inserted in the holes 10b in this case rest on a bottom section of the stabilizing element 60 in the region of a recess 60b.

The suspended ballast support 70 on the one hand receives the ballast body 88 of the second type inserted in an accommodation space 73 of the U-profile 72 which has a mass of about 25 kg. The vast majority of the mass received by the ballast support 70 is however formed by the rod-shaped ballast bodies 80 of the first type. These ballast bodies have suspension hooks 82 and supporting surfaces 84 at a proximal end 80a facing the ballast support 70. By means of the suspension hooks 82, these ballast bodies can be suspended on both sides in the legs 72a of the U-profile 72 of the ballast support 70 acting as a holding device 72a, wherein these ballast bodies are supported by means of the supporting surfaces 84 on the outer side of the holding devices 72a in order to ensure the depicted horizontal alignment. As shown, a plurality of ballast bodies 80 of the first type are suspended adjacently to one another in the direction of extension of the floor support 10. By suspending the ballast bodies 80 of the first type on both sides of the floor support 10, a torsion of the floor support by the ballasting is avoided. The ballast bodies 80 shown in Figs. 3 and 4 each have a mass of 20 kg. With a total of 24 structurally identical ballast bodies 80 of the first type in the region of the pillar 6 characterized by A in Fig. 2, a total ballasting of 480 kg is thus obtained merely by the ballast bodies 80 of the first type alone. A lower mass of 360 kg is achieved at the adjacent and left floor support in Fig. 2, because outwardly pointing ballast bodies are used there, each weighing only 10 kg, whilst accepting a torsion effect.

As has already been described and can be seen particularly clearly in Fig. 2, the ballast bodies 80 of the first type extend largely horizontally, wherein their distal ends 80b also do not come into ground contact as a result of the horizontal extension. At the same time however, the ballast bodies 80 are sufficiently low in order to remain even with their upper side below the transverse and diagonal struts 32a, 32b of the bottom segments 30 so that no relevant consideration with regard to the positioning is required.

As a result of the said design with the ballast support 70 and the ballast bodies 80, 88 of the first and second type fixed therein or thereon, the floor supports 10 are provided with a considerable ballast mass without interposed longitudinal supports 20. Forces acting from a tent pillar 6 in the direction of the arrow 4 and the arrow 5 via the baseplate 40 with the extension 46 and via the supporting member 68 vertically upwards or horizontally on the floor support 10 and the stabilizing element 60 are therefore intercepted via the ballasting loading the floor support 10 without the connection of the longitudinal supports 20 to the floor supports 10 having a crucial role for this. Of particular importance here is that the stabilizing element 60 due to its extension between the fixing device 44 of the baseplate 40 and the force input portion of the ballast support 70 forms a considerable reinforcement of the aluminium profile of the floor support 10 which is comparatively weak itself and thus counteracts its deformation. As a result of the fact that the stabilizing element 60 with the fixing device 62 can directly receive the forces introduced by the pillar 6 avoiding the floor support 10 and as a result of the fact that the mass of the ballast bodies 80, 88 of the first and second type in the area of the recess 60b directly on the stabilizing element 60 and counteracts its horizontal and vertical displacement, a part of the force acting on the fixing device 44 can be guided almost completely past the floor support 10 into the ballast support 70.

The ballast support 70 is preferably always in physical contact with the ground 2 during the expected wind loading of the tent. In this case, the connection of the ballast support 70 to the floor support by means of the bolts 76, 78 is designed geometrically in such a manner that when there is no wind or at least no upwardly directed action of force acting on the tent pillar 6, and therefore on the floor support 10 and the stabilizing element 60, the weight force of the ballast bodies acts directly on the ground via a contact surface on the underside of the ballast support and thus counteracts a displacement of the tent. When the wind attempts to lift the tent pillar 6 and thus the stabilizing element 60 and the floor support 10, the proportion of the force introduced in such a manner directly into the ground 2 is reduced and a second component of the force acts instead vertically on the floor support 10 and prevents this from being lifted.

As is deduced in particular from Fig. 2, slippage prevention devices 90 in the form of rubber mats 90 are provided underneath the supporting flanges 42, 22 as well as also underneath the ballast support 70 and underneath all the other contact regions of the base structure with the ground 2. These rubber mats 90 are vulcanized on the upper side 90a and the underside 90b and each have a high friction coefficient with the corresponding friction partners of at least 0.5 so that a comparatively low ballasting of the tent base structure, in particular of the floor support 10 is sufficient to reliably secure the tent against slipping.
