Description

Round tent and its method of manufacture

The invention relates to a round tent with ring-like wall parts as well a frame adjoining this roof part for one of the center of the Roof part inclined towards the wall parts from flexible roof skin Fabric or the like. Material. The invention also includes a method for its Manufacturing.

By US-PS 2,748,785 a frame tent with an annular wall is known, in the center of which a central mast is first set and from which radial cables are then used Ring wall to be tensioned. This creates a rope spider between that central mast as well as the ring wall, the latter anchored in the Steligrund and with larger widths must be provided with sails to the outside. One puts one on the rope spider Roof skin on canvas.

These round tents are burdened with the significant deficiency that with the erection of the ground is violated by anchors or ground foundations got to; at least the ring wall and its sails require anchors - for larger ones Spans even those elaborate foundations. For larger tent diameters, it must the middle mast, which is very annoying in itself, can also be set in the ground.

Another disadvantage has been shown that larger spans with such parasol tents cannot be achieved at all.

There is an increasing need for relatively spacious Round tents without anchoring in the ground and above all without masts in the tent be able to assemble the interior as quickly as possible; Showmen and circuses must today due to a lack of sufficient open space or to avoid soil changes Establish their businesses mostly outside the cities by laying foundations or the like, which led to a rapid decrease in visitor numbers.

In view of these circumstances, those companies feel compelled to to look for ways of building a new generation of tents without the use of Anchors or even mast foundations to be able to return to the city centers. So is It is the aim of this invention to provide a foundation and anchor-free and easy to assemble To create a round tent for larger spans, which has a mast-free interior and is easy to use.

A round tent of the type mentioned at the beginning leads to the solution of this problem Art with a base frame made of several radial profiles directed towards its center, at least one of these connecting thresholds and of the radial profiles towering stems, each with at least one coupling for a mating member a binder od. The like. Are provided, as well as with one of the radially extending binders containing roof dome with a central holding element for this both with the stems as well as a binder detachably connected to the holding member. These are after another Feature of the invention curved upwards and thanks to at least one central hinge - at least in two parts.

Within the scope of the invention lies a special one - anchoring and foundation-free - Formation of that base frame, the radial profiles of which are hinged to one stem each and with this od by an inclined and adjustable carrier made of rectangular tube. Like. Are connected.

The latter is articulated on the one hand and movable on the other attached, preferably hinged on the stem at a distance from the radial profile and on the latter set axially displaceable. This carrier has an angled sliding end, whose trajectory is flanked by tabs of the radial profile.

The unit of radial profile, articulated handle and sliding support is placed on the ground, after which the radial profiles at a distance to Center on an inner threshold rim and at the other end on an outer threshold rim hitched up and all that receives a stable and anchor-free floor frame. The carriers end at a distance from the inner sleeper rim on the tabs or the like of the radial profile and allow the vertical direction of their stems in spite of to adjust possible uneven floors.

For the connection of the roof dome, the stems end according to the invention at the top in joint parts which interact with counter elements of the roof dome; for this purpose, articulated lugs, inclined towards the center of the base frame, protrude from the stems on.

In addition, according to the invention, the upper ends of the stems with a Ring made of profiles as well as neighboring stems for the arch trusses with tension cords connected, which attack near the joint brackets.

The roof dome 3 for that anchor-free floor frame is set according to the invention especially from those - radially connected to the central holding member - bow ties together, which is preferred as a lattice girder tapering at both ends with two upper chords and a lower chord are formed.

Each of these bow ties is easy to assemble, including each joint has at least one releasable horizontal bolt around which the tie parts during the erecting can be pivoted to a limited extent.

After connecting the still articulated bow ties to the centric Holding organ and at the latest before laying the roof membrane, the roof dome must be in itself are stiffened, which is why according to the invention each bow tie at least one of the Joints a device for a rigid connection of the hinged parts having; the joint with at least one other is preferred Provided socket pin, which runs parallel to the horizontal pin of the joint.

In addition, to further stiffen the roof dome between each two arched trusses connected to these cross members are attached over which at least one radial intermediate arch is at a distance from the cross member.

The intermediate arches curved in accordance with the arch binders are advantageous on the cross member or on a support profile that is parallel to it and curved axially upwards attached.

According to the invention, these intermediate arches are also part of the coupling frame on - if necessary, statically simpler than the main posts for the arch trusses - Intermediate stems, preferably articulated, releasably fixed.

The method according to the invention for erecting or erecting the round tent is now characterized by 5 that a floor frame is anchored on a Steligrund with radial profiles and stems protruding therefrom and at least one of the radial profiles connecting threshold wreath is set up, after which multi-part arched trusses with open joint parts laid flat and radially and with a central holding element are connected that then holding member and bow tie using Pull ropes are lifted up at the hinge points by a central lifting device the arch trusses determine a dome shape, after which the arch trusses are made lifted evenly with the lifting organ to the upper end of the stems and at it be hinged. The articulated parts of the bow ties are preferred before the Lift to the joints of the stems rigidly together connected as well as after fixing the free ends of the bow ties to the free Ends of the stems these are connected in pairs by horizontal tension ropes.

The roof skin is placed on the roof dome so that between the Between arches and radial grooves tapering towards the holding member arise For example, the roof skin on the arched trusses forms the gutter depths.

This creates a round tent with a larger span with a mast-free interior, that can be set up without anchors, e.g. also for use in pedestrian zones or the like. Is suitable.

At B are in Fig. 1 stage fixtures. indicated which instead of or in addition to Manege M can be provided.

Each of the main posts 21 ends at the top in a pivot bearing 41 with a radial inner distance k (e.g. 14 cm) from the handle axis A Hinge pin 42, which is a bearing tube 43 of a curved truss or arched truss 46 interspersed; this is with an end shoe 44 including stiffening web 45 to that Bearing tube 43 welded on.

Each bow tie 46 has a central joint 47 and a head joint 48 on which the latter connects it to a zenith crown 50. The better overview For the sake of this, let the lower truss section be the truss foot 46t and the upper truss section referred to as binder head 46k.

In Fig. 6, the distance m between the lower chord 49t and the Upper chords 49h of the cross-sectionally triangular bow tie 46 near the end shoe 47 24 cm and increases towards the central joint 47 to almost 60 cm; at the head joint 48 that belt distance m measures about 30 cm. The projection distance n of the central joint 47 from the shaft axis A is provided with 540 cm.

Eight of these arched trusses 46 extend from the main posts 21 and end at that zenith crown 50 in a determined by its diameter q of 2.40 m Distance from each other. This creates a column-free roof dome 51 of a central one Height cl of about 7.00 m; the mean total height c of the round tent 10 is therefore with about 10.00 m to be assumed at a medium vertical distance el of the central joint 47 from the joint end 41 of the main post 21 of approx. 5.00 m.

7, 8 show that the zenith crown 50 consists of two trusses 52 spaced tubular rings 53 consists. The end shoe 44 of the bow tie 46 is not illustrated by a roller joints 54 for reasons of clarity Hinge pin between a head plate 55 and a connection plate 56 on the zenith crown 50 connected. Clear. becomes in Fig. 8 the triangular cross-section of the truss from two upper chords 49h and one lower chord 49t at a distance t of 35 cm.

The central joint 47 at the joint of the two arch support sections 46t 46 is designed similar to the head joint 48 (Fig. 9,10). At the lower end of the tie head 46k sits an end shoe 58 with lateral sockets 59 made of two facing each other Gutter profiles for in the selected embodiment consisting of rectangular pipe - Cross members 60 of the roof dome 51, which according to FIG. 11 form a central roof ring.

On that cross member 60 are two attached to the zenith crown 50 Intermediate sheet 61 on and a middle intermediate sheet 62, which the cross member 60 slightly overlaps. These intermediate sheets 61, 62 ps a according to Fig.

13 upwardly curved tube with a vertex dimension u of 45 cm rest with their ends remote from the zenith crown 50 in joints 41z of the intermediate stems 22 and are at a distance y above the cross member 60 in shoes 63 attached to it to enable an applied roof skin 90, according to FIG. 12 between the radial Carrying elements 46, 61, 62 of the roof dome 51 cross-sectionally to form grooves 91, which, if necessary, allow radial water drainage to a top gutter.

In one embodiment of the round tent 10, those shoes are 63 on a rectangular tube that runs next to the cross member 60 and is in turn upwardly curved (150 x 100 x 6), which is indicated in Fig. 10 and 12 at 64 and likewise is held in the sockets 59.

The round tent 10 according to the invention can be used without any damage to the Steligrundes G can be set up and used by anchors or sails. To the assembly of the floor frame 11, which can be removed in particular from FIG. 1, with its protruding stems 21, 22, the arch trusses 46 are laid out as shown in FIG. that the binder head 46k touches the zenith crown 50 centered in the center Z and the Binder foot 46t protrudes beyond the plan of the floor frame 11. The two parts 46t, 46k of the bow tie 46 are on the one hand in the area of the central joint 47 with one another articulated and articulated to the zenith crown 50 by the head joint 48. At the hinge points 47, 48 pull cords 70, 71 engage, which according to the Number of bow ties 46 in plan view like a spider from one for the sake of clarity The crane hook not shown in the drawing goes out and an even Ensure the lift of the bow ties 46 in the hanging position shown in FIG. 14, in which the dome shape of the roof dome 51 is reached, so that the lower not shown Pivot pins can be inserted into the central joints 47 and the head joints 48; these serve as locking devices for those joints 47, 48 and stiffen them Coupling parts 46t, 46kX 50 to each other.

Subsequently, the roof dome 51, which has been completed in this respect, is raised and with the free ends of the bow ties 46 placed on the main stems 21 and there connected to the joints 41/42. Before the roof dome 51 is raised, the arch trusses 46 still provided with the cross members 60, possibly - but not necessary - With other transverse profiles 66 that are spaced apart from the channel formation described the support surfaces of the bow ties 46 and the intermediate sheets 61, 62 be held have to.

After completing the dome 51 and connecting it to the Stems 21, 22 and after attaching tensioning cables 68 between connections 69 at the upper end of the main posts 21, the roof skin 90 is placed, which is preferred is composed of a center piece 89 and four side parts 88; the side panels 88 are with the middle piece 89 in the area of the dash-dotted line 87 in Fig. 11 tightly connected; the length of the side parts 88 is the rest of the quadrant division Q adapted to the peripheral support of the roof skin 90 are shoes 85 of the styles 21, 22 edge tubes 84 inserted, which may be or have keder profiles can.

When dismantling the round tent 10, the hinge pins are first 42 pulled, after which the tie ends 43 then released by its own weight the bow tie 46 migrate slightly downwards and so towards the center Z. move. This is how it becomes possible, the dome 51 between lower the handles 21, 22 as a whole on the pulling ropes 70, 71 (see Fig.

14); is the roof dome 51 again arrived near the ground, the lower hinge pin od. The like removed, and joints 47, 48x allow placement of the coupling parts 46tS 46k, 50 on the plot G.
