DETAILED DESCRIPTION

(11) As shown in FIG. 1, the roof structure of the tent rests on the end of the supports 5 which is at the top in the set-up state of the tent. In the case of a square tent structure, the four respective corner areas of the tent roof are therefore disposed on the supports 5 correspondingly arranged in a square.

(12) The supports 5 are connected to each other via L-shaped connecting elements. As shown in FIG. 1, at least three outer scissors-type grid sections 23 run on each outer side of an exemplary square tent structure according to the invention. The supports 5 are thus connected to each other by means of scissor-type grid sections 23.

(13) The outer scissor-type grid sections 23 running circumferentially around the outer sides of the supporting framework 6 as well as the scissor-type grid sections 23′ directed inwards into the tent in turn are connected to each other by means of a plurality of upper and lower connecting elements 34, 34′; 35, 35′ (the numerals 28, 28′; 29, 29′ mentioned in the text are not shown in FIG. 1), which are illustrated by way of example in FIG. 1. If three scissor-type grid sections are arranged on one side, at least two upper and lower connecting elements are thus provided for the connection between the outer scissor-type grid sections 23 and the scissor-type grid sections 23′ directed inwards into the tent.

(14) When looking at one side of the supporting framework according to the present invention in FIG. 1, in sectional view A-A′ according to FIG. 2, it has a corner support 5 on each of its outer sides, FIG. 1. The corner supports 5 are connected to each other by means of at least three scissor-type grid sections 23. The corner support 5 which is on the left when viewed from the front is first connected to the adjacent scissor-type grid section 23 by means of an upper and lower connecting element 36, 36′. This scissor-type grid section 23 is then followed by a second scissor-type grid section 23, with the connection 35, 35′ these two sections in turn being made by means of a connecting element having a T-shape in a preferred embodiment. The third scissor-type grid section 23 is arranged adjacent thereto, which in turn is connected to the second scissor-type grid section 23 by means of a preferably T-shaped connecting element 34, 34′. Then the third scissor-type grid section 23 in turn is connected to the corner support 5 which is on the right when viewed from the front by means of a further upper and lower connecting element 33, 33′.

(15) Viewed individually, each side of the supporting framework thus has four upper and four lower connecting elements.

(16) Since this is a scissor-type grid structure, a corresponding number of lower connecting elements is added, because the connecting elements are arranged at the point where one scissor-type profile has its maximum spacing of its profile elements and is connected to the adjacent scissor-type profile, where this scissor-type profile also has its maximum distance in its connecting area. Here, this distance, which is at its maximum in the pulled-apart state of the scissor-type grid section, is abbreviated with “d”, cf. FIG. 1.

(17) The connecting elements used within the scope of the invention preferably have a T-shaped receiving structure for the connection of the outer scissor-type grid sections 23 to each other. This is indicated in FIG. 2 with the pairs of numerals 28, 28′; 29, 29′; 31, 31′; 32, 32′; 34, 34′; 35, 35′; 37, 37′; 38, 38′, with the scissor-type profile elements running essentially parallel to the respective side of the tent. The numerals 28′, 29′, 31′, 32′, 34′, 35′, 37′, 38′ with an apostrophe stand for the lower connecting elements. The numerals 28, 29, 31, 32, 34, 35, 37, 38 indicate the upper connecting elements. Scissor-type grid sections 23′ directed inwards into the tent branch off from these connecting elements, which are also referred to as three-way connectors. The connecting elements are thus not aligned with a two-dimensional course, which would be sufficient for a connection of the scissor-type grid sections to each other, but they have a receiving structure branching off therefrom at a right angle, which receives the profile elements of the scissor-type grid sections 23′ running towards the inside of the tent.

(18) As described above, the scissor-type grid sections 23′ directed inwards into the tent and extending from the connectors 51-54, 51′ 54′ of the central diagonal bars 47-50 are also arranged at the positions 28, 28′, 29, 29′, 29′, 31, 31′, 32, 32′, 34, 34′, 35, 35′, 37, 37′ and 38, 38′. As three-way connectors, the connecting elements 28, 28′, 29, 29′, 31, 31′, 32, 32′, 34, 34′, 35, 35′, 37, 37′ and 38, 38′ thus have a T-shaped configuration. They are located at the point where the respective scissor-type grid profile 23 is at its highest position, FIG. 1.

(19) At the respective position located vertically at the bottom, the arranged scissor-type profile also reaches its lowest position.

(20) The lower scissor-type grid elements 26, 27 of the outer scissors 23 shown in FIG. 1, which run from bottom left to top, are hinged to the upper connectors 35 and 34; and, as shown in FIG. 7 are hinged with regard to the pair of connectors 28, 28′. The scissor-type grid elements 24, 25, which run from top left to bottom, are hinged to the lower connectors 35′ and 34′, which are likewise configured in a T-shape analogous to the connectors 35, 34 arranged at the top. The scissor-type grid sections 23′ further branch off from these T-shaped connectors towards the connectors 51-54, which provide a connection also of these scissor-type grid sections 23′ to the central diagonal bars 47-50, FIG. 2, FIG. 4, FIG. 5. The scissor-type grid section 23 comprises profile elements 24, 26, 25, 27 (shown in FIG. 1 by way of example) extending at an angle to each other, hinged together and crossing each other, which are brought into contact with each other substantially vertically in a folded state.

(21) The connectors of the corner supports 5 with the scissor-type grid sections 23, namely the connectors 30, 30′; 33, 33′; 36, 36′; 39, 39′, have a so-called L-shape as shown in FIG. 2.

(22) These connectors serve to connect the outer scissor-type grid sections 23 at an angle. Here, too, the reference numerals 30′, 33′, 36′, 39′ with an apostrophe stand for the lower connecting elements, while the numerals 30, 33, 36, 39 refer to the upper connecting elements.

(23) The inner upper connecting elements 51, 52, 53, 54 and the inner lower connecting elements 51′, 52′, 53′, 54′ are configured in the form of four-way connectors or cross-shaped connectors, since, on the one hand, they connect the profile elements of the scissor-type grid sections 23′ directed inwards into the tent at the point where they run towards each other in a crosswise manner when branching off from the respective adjacent outer sides. On the other hand, they receive the four inner scissor-type grid sections 23″, which are aligned to each other in a rectangular manner, cf. FIG. 2.

(24) The four inner scissor-type grid sections 23″ are a kind of square, in the center of which the central post 7 is located. The central post 7 in turn is connected to the four-way connectors described above via four central diagonal bars 47, 48, 49, 50, FIG. 2, FIG. 4, with a connection to the upper connectors 51, 52, 53, 54 being suitable.

(25) In the set-up state, in which the tent roof rises in its highest elevation above the supports of the supporting framework of the tent, the profile elements extend in a scissor shape beneath the tent roof as shown in FIG. 1 and FIG. 7. Due to the screen 3 of the fabric of the tent roof 2, the scissor-type grid sections 23 are not visible to the viewer.

(26) The supporting framework 6 arranged inside the tent, i.e. the roof structure of the tent, in turn has at least one central post 7, which has an indirect support in the roof structure, FIG. 1 and FIG. 4.

(27) The central post 7 is directed towards the fabric 2 of the tent roof and holds it directly so that the apex 22 of the tent roof fabric is located as far away as possible from the remaining structure of the supporting framework. This results in the typical pyramid-like or pagoda-like tent roof structure, FIG. 1.

(28) As shown in FIG. 9, a device 8, which serves to firmly connect the fabric of the tent roof 2 to the central post 7, is connected to this central post.

(29) This device preferably has a closing mechanism on the upper front side of the apex of the tent roof in order to seal this area in a watertight manner.

(30) The device 8 comprises a first body 11, which serves to be connected to the central post, and a second body 12, which serves to be connected to the first body 11. The latter directly holds the fabric of the tent roof 2, which is inserted between the two bodies 11 and 12. For the connection between the two bodies, the fabric of the tent roof 2 has an opening, which is surrounded by a rigid ring (not shown) bordering the edge of this opening. This ring is thus inserted between the aforementioned bodies 11 and 12 in such a manner that a connection between them is made possible. However, other related structures are easily possible for the person skilled in the art.

(31) In particular, the first body 11 has a substantially mushroom-shaped form and comprises a vertically running wall, which preferably has a tubular configuration 13 and surrounds a hollow space 14. This first body 11 serves to be fitted into the central post 7 and to be inserted into its hollow space by means of the wall of the tube 13. The first body 11 can be pulled out of the central post again.

(32) After the first body 11 has been inserted into the central post 7, the ring of the fabric of the tent roof 2 slides over the head of this body. The ring rests, in particular, on the flat portion 16 of the head 15, which otherwise has a curved configuration 17.

(33) The first body 11 is connected to the second body 12, which also has a substantially mushroom-shaped configuration. The second body 12 also comprises a vertically running wall of a tube 19 surrounding a hollow space.

(34) At the head end of the wall of the tube 19 of the second body 12, a cylinder cap is arranged, which serves to cover the ring of the fabric of the tent roof 2 and to interact with a lid in a manner known per se so as to close the hollow space inside the second body 12. Thus, this lid also serves indirectly to close the hollow space of the central post 7 when it is in a state of non-use, for example, so that rain, dust or other substances cannot penetrate into the hollow space.

(35) If required, a further component, for example a pole 9, which receives a rotatable object 10 or an advertising banner, can be placed, for example inserted, into the hollow space as indicated in FIG. 1.

(36) The essential point about a folding tent is that due to the aforementioned structure, the roof can be penetrated from above with the further pole 9, which receives the rotatable object 10. The arrangement remains nonetheless watertight.

(37) In the state in which the tent is not set up, the central post 7 is first only connected to the device 8 at its end which is at the top in the set-up state, while its end which is at the bottom in the set-up state of the tent is loose, FIG. 4. Regardless thereof, however, the central post is connected to the four-way connector, i.e. to a part of the supporting framework.

(38) As can be seen in FIG. 2 and FIG. 3 based on the example of a tent measuring 5×5 m, which has three circumferential scissor-type grid sections 23 of the roof structure 6 on each side, such structures lack a center or junction point of the tent extending from the same scissor-type grid sections, i.e. these scissor-type grid sections are not the direct starting point for profiles extending therefrom towards the inside of the tent and running towards a central post arranged in the middle of the tent, which receives the apex of the roof.

(39) Accordingly, the invention therefore provides the arrangement of the four central diagonal bars 47-50, FIG. 2. These diagonal bars are automatically brought into position by pulling the tent apart and thus also effect the central positioning of the central post 7, as is described in more detail below. As already described above, the diagonal bars are hinged to four four-way connectors 51-54, 51′-54′, which are diagonally spaced apart from each other and form a square arrangement, FIG. 2.

(40) As mentioned above, the upper connectors 51-54 and the lower connectors 51′-54′ each are connected via the four-way connectors 51, 51′, 52, 52′, 53, 53′, 54, 54′ to the scissor-type grid sections 23′ directed inwards into the tent, which in turn are hinged to the outer scissor-type grid sections 23.

(41) Thus, the structural connection between the central post 7 and the outer scissor-type grid sections 23 running circumferentially around the outer sides is achieved by means of the central diagonal bars 47-51 and the scissor-type grid sections 23′ directed inwards into the tent. In the case of a square floor plan of a tent, this structure provides the division into nine square partial floor plans as already mentioned above, FIG. 2, FIG. 3.

(42) The four central diagonal bars 47-50 are connected to the central post 7 by means of a central connector 42, FIG. 1, FIG. 4, FIG. 6. The four central diagonal bars are hinged to the central connector 42 in a manner known per se. In its center, this connector is provided with a hollow space, into which the lower portion of the central post 7 is inserted. The connector 42 thus acts as a guide or motion link for the central post 7. Together with the central post 7, the central diagonal bars 47-50 are moved upwards when the tent is set up so that the final apex of the tent roof is formed and the tent assumes the pyramid-shaped or pagoda-shaped tent roof shape.

(43) When the tent is set up, the central post 7 still hangs loosely down from the device 8, cf. FIG. 4.

(44) For the further setting up of the tent and for the purpose of obtaining the pyramid-shaped or pagoda-shaped tent roof structure, a handling bar 41 is provided according to the invention, which is inserted from below into the hollow space 40 of the central post 7 via the aforementioned connector 42, FIG. 1, FIG. 4.

(45) The resulting overall connecting structure consisting of the central post 7 and the handling bar 41 is then pushed upwards manually or mechanically, for example by means of a wire rope hoist, a crank, a toothed rack, a gearing mechanism, or by a motor.

(46) A corresponding opening 44 in the central post 7 or handling bar 41 is then used to press in a spring-loaded bolt (not shown) inserted therein, referred to below in simplified terms as spring bolt, which snaps into a corresponding recess in the guide of the connector 42 as soon as there is a local overlap of these areas. This lock can be released again by means of a push button 45, FIG. 6. In order to facilitate operation, the handling bar 41 has a hand knob 46, FIG. 4.

(47) This combination enables a considerably larger height arrangement of the apex of the roof.

(48) As already described above, the scissor-type grid sections 23 of the supporting framework 6 running on the outer side of the tent are connected to each other by means of connectors at the top 28-39 and connectors at the bottom 28′-39′ arranged on the profile elements of the scissor-type grid sections 23 so that the tent has a circumferential scissor-type grid arrangement on all sides, FIG. 1, FIG. 2.

(49) It has already been described above that in the area of the upper and lower connectors 28, 28′; 29, 29′; 31, 31′; 32, 32′; 34, 34′; 35, 35′; 37, 37′ and 38, 38′, the scissor-type grid profiles of the circumferential scissor-type grid sections 23 of the supporting framework 6 reach their maximum spacing at the distance “d” if and insofar as they are in the pulled-apart state, FIG. 1.

(50) This area of their maximum spacing serves to arrange stabilizer devices 68-75, FIG. 3. These stabilizer devices serve to provide improved stability of the tent by connecting the scissor-type grids via the stabilizer devices at their greatest distance “d”.

(51) For this purpose, the scissor-type profile elements of the scissor-type grid sections 23 running at the top and running at the bottom are connected to each other in the area of their maximum spacing “d”. Two connecting tubes are provided for this purpose, namely a connecting tube at the top 76 and a connecting tube at the bottom 77, cf altogether FIG. 1, FIG. 7.

(52) Therefore, in the example case of a tent measuring 5×5 m, the stabilizer devices 68-75 are each arranged between the connectors 30, 30′, 33, 33′, 36, 36′, 39, 39′ configured in the form of corner connectors and enclosed between the upper connectors 28, 29, 31, 32, 34, 35, 37 and 38 and the lower connectors 28′, 29′, 31′, 32′, 34′, 35′, 37′ and 38′, and each have the upper connecting tubes 76 and the lower connecting tubes 77, as is further described below, FIG. 2, FIG. 3.

(53) In addition, the stabilizer devices 68-75 are connected to the central post 7 or the handling 41 bar for the central post 7 by means of the scissor-type grid sections 23′ and the central diagonal bars 47-50.

(54) This causes a more or less fanned-out application of force starting from the central post 7 or the handling bar inside the tent towards the outer side of the tent.

(55) The two connecting tubes 76 and 77 thus interact with the aforementioned upper connectors and the lower connectors, which are not only connectors for the outer scissor-type grid sections 23 running circumferentially around the outer sides of the tent, but which are also (indirect) connectors to the central post 7 or handling bar 41, FIG. 2, FIG. 3, FIG. 7.

(56) The (respective) lower connecting tube 77 is movable in a lower connector 28′, 29′, 31′, 32′, 34′, 35′, 37′, 38′. The lower connector has a tubular configuration, i.e. it forms a guide or motion link for the lower connecting tube 77. The connecting tube 77 can be guided in a movable manner through the tubular hollow space of the lower connector, which is preferably configured in the form of a cylindrical hollow space, FIG. 7, FIG. 8.

(57) It is pushed upwards by means of a hand knob 82 arranged at the lower end of the lower connecting tube 77 through the hollow space of the connector 28′, 29′, 31′, 32′, 34′, 35′, 37′, 38′, and connected by means of a connecting part 78, in which a protruding spring bolt 79 is mounted, to the upper connecting tube 76, preferably via an opening 80 provided therein, into which the spring bolt 79 snaps when it reaches the opening 80 as a result of pushing the lower connecting tube 77 upwards.

(58) In order to release this connection between the two connecting tubes 76, 77 thereby occurring, a push button 81 may be provided, by means of which the spring bolt 79 can be pushed back into the lower connecting tube so far that it can, for example, be pulled out of the upper connecting tube 76 with a larger diameter again, or the spring bolt 79 is pushed back through the opening 80 with the thumb to release the connection.

(59) As soon as the tent is set up in its basic form, which is the case when the handling bar 41 of the central post 7 has brought the latter into its final position, the stabilizer devices 68-75 are used as described above, i.e. the tubes 76, 77 are connected to each other.
