"Umbrella Pavilion"

The present invention relates to an umbrella pavilion comprising a fixed supporting structure and a superstructure with a tarpaulin, which can be brought into a use position in which the tarpaulin assumes an umbrella-like shape and spans the supporting structure of the substructure, wherein the superstructure can be brought into a transport position with the tarpaulin folded in, in which the umbrella pavilion assumes a compact, preferably approximately cuboidal shape.

Umbrella pavilions of the type mentioned above serve

&iacgr;&ogr; for example as sales pavilions or bar pavilions on

events and are usually designed to be mobile. This means that the umbrella pavilion is, for example, either designed as a container so that after being transferred to a transport position it can be transported on the road using a suitable transport vehicle. The umbrella pavilion itself can also be designed with a chassis with wheels so that it can be transported on the road as a trailer using a towing vehicle. Due to the Road Traffic Licensing Regulations, the umbrella pavilion must have a compact design when being transported and certain dimensions must not be exceeded; this applies to the width, length or height. Since an umbrella pavilion is usually relatively tall when in use due to its umbrella-like construction, corresponding structural changes are usually necessary when it is transferred to the transport position in order to reduce this height so that it is possible to drive under bridges or tunnels in road traffic.

With the well-known conventional umbrella pavilions, it is often the case that when transferring them into the transport position, parts have to be dismantled, which is usually done by hand.

, so that the dismantling or reconstruction of the umbrella pavilion is labor-intensive. Dismantling or reconstruction often requires several people who are employed for a longer period of time. This dismantling work and, conversely, the reassembly when re-erecting the umbrella pavilion are therefore labor-intensive and also costly.

The object of the present invention is therefore to provide an umbrella pavilion of the type mentioned at the outset, in which the transfer into the transport position from the use position and vice versa is possible with simple means in a comparatively short time and with little personnel expenditure.

The solution to this problem is provided by an umbrella pavilion according to the invention of the type mentioned at the beginning with the characterizing features of the main claim. According to the invention, a central, elevating mast is provided to which the tarpaulin is attached. When the mast is raised into the position of use, the tarpaulin is stretched out in the shape of an umbrella, and when the mast is lowered into the transport position, the desired compact design of the umbrella pavilion for transport on the road is obtained. This eliminates the critical size in the height dimension, which results from the relatively high central mast, by lowering the mast for transfer to the transport position. This lowering of the mast can basically be done manually or via a suitable drive. In the latter case, various design solutions are conceivable. If it is a sales pavilion or bar pavilion with corresponding fittings, it only has to be ensured that the retractable mast can be lowered into the intended transport position without causing any damage below the

The fixtures provided for the masts can cause interference. However, various structural solutions are possible without any problems. For example, if there are fixtures underneath the mast, you can simply make an opening in them into which the mast can then be moved. You can also provide a central column into which the mast can be moved. The mast can be made of several telescopic sections, which can then be extended into the position of use when it is raised.

According to a preferred development of the present invention, the supporting structure of the umbrella pavilion is provided with bows which are pivotably attached about an axis. The tarpaulin can be secured to these bows. When the mast is raised, these bows then pivot about a pivot axis into an upper position which they assume when the umbrella pavilion is in use. This pivoting movement can be caused by the tarpaulin exerting a tensile force on the bows and pulling them up. This tensile force does not have to be exerted via the tarpaulin itself, but appropriate straps can be incorporated into the tarpaulin to prevent the tarpaulin from tearing. The tarpaulin is also preferably attached to the upper end area of the mast so that when the mast is raised, the tarpaulin pivots the bows up as soon as the tarpaulin is taut. The pivot axis of the bows is preferably a horizontal pivot axis. Furthermore, this pivot axis is preferably located radially further outwards from the center of the umbrella pavilion when looking at the umbrella pavilion from above. The pivot axes of the bows are therefore preferably located approximately in the outer area of the supporting structure of the substructure of the umbrella pavilion.

There are various possible structural solutions for making the bows pivotable. For example, the supporting structure of the substructure can comprise crossbars or beams that extend diagonally or radially outwards from the middle of the substructure, depending on the floor plan of the supporting structure. The elevating mast is preferably located in the middle, so that the said crossbars or beams extend outwards from the mast. Between these beams or crossbars of the supporting structure there are then preferably bearing beams, i.e. beams on which the bows are pivotably mounted. If the mast can be raised to bring the umbrella pavilion into the position for use, then a mast guide is preferably provided. The said crossbars of the supporting structure can, for example, extend outwards from this mast guide. However, if the mast is made up of several parts so that it can be extended telescopically, for example pneumatically or hydraulically, such a mast guide is not absolutely necessary. The mast guide mentioned is used in particular when the mast remains essentially the same in length when it is lowered, so that the mast is guided through the mast guide. The pivoting bows mentioned can be swung up over the tarpaulin when the mast is raised. When the mast is lowered, the bows can swing into the position intended for the transport position of the umbrella gazebo due to their own weight. The position of the bows in the position of use of the umbrella gazebo is preferably inclined or almost horizontal. When swiveling up, the pivoting bows preferably hit a stop in an almost horizontal position, which prevents them from swiveling up any further.

By extending the mast further, the tarpaulin can be pulled tightly against the fixed bows.

-5-

The position of the bows in the transport position is preferably such that the bows largely rest against the supporting structure of the substructure. Ideally, the bows are then more or less vertical and extend downwards so that they protrude outwards as little as possible and the entire structure takes on as compact a design as possible. Furthermore, the mast ideally moves down far enough in the transport position that in the fully retracted position it protrudes as little as possible above the supporting structure of the substructure. Ideally, the transport position of the umbrella pavilion results in a compact design that takes up roughly the space of a cuboid or a prism, depending on the floor plan. If the substructure has a rectangular floor plan, the design is usually cuboid.

It has already been mentioned that the mast can be raised either manually or by means of a drive or, if necessary, gear means. An advantageous design solution involves the use of one or more traction cables, which can also be operated manually or via a motor-driven cable winch. Other solutions involve hydraulic or pneumatic raising or telescopic extension of the mast. Still other solutions involve the use of gear means such as racks or the like for extending the mast.

The advantage of using a motor-driven cable winch is that it can be stored in the area of the base of the umbrella pavilion to save space and can be conveniently operated from there. The mast can then be pulled up into the position of use using a pull rope that attaches to the mast. In order to achieve a better power transmission, at least one

-6-

A redirection of this traction cable is provided. The traction cable can also be redirected so that it indirectly pulls up the mast and, for example, the traction cable can be fixed to the end of the mast guide.

A further advantageous development of the solution according to the invention provides that the bows are designed in an angled manner. The bows preferably have a longer leg and a shorter leg protruding from this, so that an L-shape is created. This has the advantage that the pivot axis for the pivotable bows can be arranged on the shorter leg, so that the pivot axis runs at a distance from the longer leg. This results in significantly better torques, particularly at the start of the pivoting movement, and thus overall better force ratios when the bows are pulled up when the mast is raised by means of the tarpaulin connecting the mast to the bows.

The supporting structure of the substructure can, for example, be supported by columns that are arranged approximately at the corners of a rectangle if the substructure has an approximately rectangular floor plan. The supporting structure of the substructure can also be self-supporting towards the outside, in which case a central column is preferably provided from which the said crossbeams or supports extend outwards in a self-supporting manner.

The features mentioned in the subclaims relate to preferred developments of the solution to the problem according to the invention. Further advantages of the invention emerge from the detailed description below.

First, reference is made to Fig. 1a to 1c. The illustration shows an umbrella pavilion according to the invention, the drawings being schematically greatly simplified and only those parts of the umbrella pavilion being shown that are of importance in the context of the present invention. The umbrella pavilion generally has fittings not shown here and is either designed on a substructure as a container so that it can be transported on a towing vehicle, or the umbrella pavilion has its own chassis with wheels so that it can be transported as a trailer with a tractor. All fittings and the parts of the supporting structure, which are essentially shown in Fig. 1a to 1c, are arranged when the closed tarpaulin is lowered so that an approximately cuboid-shaped body remains, as can be seen from the views according to Fig. 1a to 1c. This ensures that the corresponding dimensions are such that the umbrella pavilion according to the invention can be transported on a vehicle as a container or behind a towing vehicle as a trailer and the

-9-

the relevant provisions of the Road Traffic Licensing Regulations are complied with.

Reference is now made to Fig. 1a. The umbrella pavilion according to the invention is designated overall by 10 and comprises a substructure in the form of a platform 11 on which a central mast 12 is arranged and four columns 13 arranged approximately in the corner areas of the platform, which are arranged in such a way that an approximately rectangular floor plan results in the top view according to Fig. 1b.

&iacgr;&ogr; Between the central mast 12 and the corners of a

A number of supports 14 or crossbeams run along the columns 13 arranged in a rectangle, of which there are a total of six in the exemplary embodiment, as can be seen from Fig. 1b. Four crossbeams 14a running diagonally from the mast 12 to the columns 13 are provided in a cross-shaped arrangement, and two crossbeams 14b running transversely from the central mast 12. This provides a load-bearing structure which can be stiffened by further supports if necessary. Parallel to the transverse crossbeams 14b, in the outer area, running approximately between each two columns 13, there are tubular bearing supports 16a, for example, of which there are two in total, with two bows 15 being pivotably mounted on each of these bearing supports 16a. Running in the longitudinal direction, also approximately between two columns 13 or offset somewhat further inwards, there are two bearing supports 16b, on each of which three further bows 15 are pivotably mounted. The bows 15 have different lengths, as can be seen from the partially opened position according to Fig. 2b or the fully opened position according to Fig. 3b.

In total, in the embodiment according to Fig. 1b, there are two times two, i.e. four, bows 15 on the transverse sides and two times three, i.e. six, bows 15 on the longitudinal sides of the construction. In

-10-

the drawing Fig. 1b and also Fig. 1c show the cable winch 17 which is arranged below in the corner area near one of the pillars 13 and which is attached to a traction cable by means of which the central mast 12 (see Fig. 1a) is pulled up in order to open the umbrella pavilion. The sequence of movements when opening the umbrella pavilion can be seen particularly well by comparing the respective positions in Fig. 1a, Fig. 2a and Fig. 3a or Fig. 1c, Fig. 2c and Fig. 3c. Firstly, the drive of the cable winch causes the traction cable, which is attached to the mast via a cable guide (to be explained later), to lift the mast, with Fig. 2 showing a corresponding intermediate position during the opening process. The bows 15 pivot about a horizontal pivot axis which goes through the bearing supports 16a, 16b into the position shown in Figs. 2a to 2c, i.e. the bows 15 swing outwards.

The tarpaulin 18, which can be clearly seen in Fig. 1a and Fig. 2a, is attached to the mast 12 in the upper end area and also to the bows 15. In order to avoid excessive strain on the tarpaulin 18, the tensile force is sensibly transmitted via straps incorporated into the tarpaulin, which are not shown in the illustration according to the figures, which are schematically simplified. Fig. 2a, however, makes it clear that the tarpaulin engages the bows 15 when the mast 12 is raised, with these bows 15 having an angular shape and their pivot axis 19 lying at the end of the shorter leg 15a. This ensures that a tensile force is exerted on the bows via the tarpaulin or the straps incorporated into it right at the start of the opening movement, and a favorable torque is present, because the pivot axis 19 is not in the extension of the longer leg of the bow 15, but at a distance from it. This creates a lever effect at the beginning of the opening process. When the umbrella pavilion is closed, the bows 15 simply fall back into the lower position shown in Fig. 1a due to their own weight.

closed position (transport position), by lowering the mast 12 to the lowest position.

In Fig. 2c it is also clearly visible that the middle bows 15m are longer than the outer bows 15z and therefore, for a given opening position of the umbrella pavilion, the middle bows 15m are at a different angle to the support structure than the outer bows 15z. In this regard, reference is also made to the illustration according to the top view of Fig. 2b.

If, starting from the illustration in Fig. 2a, the mast 12 is raised further, it finally reaches the uppermost end position shown in Fig. 3a. Fig. 3a shows the end position of the bows 15 and one can see that these are not swung up to a horizontal position but only to an inclined position, whereas the bows 15 in the starting position according to Fig. 1a (transport position) are aligned with their longer legs approximately vertically. Fig. 3a also shows that the mast 12 in this position of use of the umbrella pavilion has been raised so high that the space 20 under the mast remains free and is available for use by the sales staff working there. From Fig. 3b one can see that the tarpaulin 18 in the stretched out state has an approximately ten-sided outline in plan view since there are a total of ten bows 15, namely 2 by 3 on the long sides and 2 by 2 on the short sides. Due to the greater length of the bows 15 on the long sides, the tarpaulin extends further away from the approximately rectangular platform 11 than on the transverse side. The central mast 12, which is raised to open the umbrella pavilion, moves in a guide 21 provided for this purpose, which is located at the intersection point of the six cross members 14a, 14b (see Fig. 1b) and which is connected to the cross members.

A detail regarding this cable guide for the cable pull in the umbrella pavilion according to the invention can be seen in the view according to Fig. 5, which shows the lower end area of the mast 12. As can be seen, in Fig. 5 the mast 12, which is vertically movable in the mast guide 21, is shown in a largely upper position. The cable 22 coming from the cable winch 17, not shown in Fig. 5 but visible in Fig. 3c, is deflected by approximately 90° via a deflection roller 23 in the area of the mast guide 21 and then runs approximately vertically parallel to the mast 12 to a deflection at the lower end of the mast 12 consisting of two deflection rollers 24, 25, which lead to a 180° deflection. The end of the cable 22a is then attached to the stationary mast guide 21, while the two pulleys 24, 25 over which the cable 22 is guided are located at the lower end of the vertically movable mast 12. If a pulling force in the direction of the arrow in Fig. 5 acts on the cable 22 when the motor of the cable winch is operated, this leads to the mast 12 being raised upwards in the direction of the arrow. If, on the other hand, the cable 22 is released from the cable winch, the mast 12 moves back to its starting position as shown in Fig. 1a, which corresponds to the transport position. The force ratios are improved by deflecting the cable 22 once by 90° and once by 180°. The pulley 23 on the mast guide 21 can also be seen in Fig. 1a. From the left end 22b shown in Fig. 5, the cable extends approximately along one of the supports 14a, initially horizontally (see Fig. 1b) and then runs from there, after a deflection of 90°, vertically downwards to the cable winch 17 arranged approximately in the corner area at the foot of one of the columns 13 (see Fig. 1b and 1c).

Fig. 4a to 4c show a further embodiment of the present invention. In this variant, instead of the columns 13 arranged approximately in the four corners of a rectangle as in the

-13-

In the embodiment of Fig. 1b, only one central column 33 is provided, which takes on the supporting function of the otherwise four columns. The supports 14a, 14b extending outwards from there are self-supporting at their ends. The mast 12 is again guided so as to be vertically movable and moves into the column 13 for the transport position, or the column itself is designed to be telescopic, whereby instead of a cable winch and a cable pull to move the mast, it can also be moved out of the column 13 hydraulically or pneumatically or, for example,

β ...

The design variant according to Fig. 4a to 4c has the advantage that the sales staff working in the sales pavilion have more freedom of movement in the outer areas, since the outer columns 13 of the supporting structure are omitted. Otherwise, the principle of opening up the umbrella pavilion by raising the mast 12 and pivoting up the bows 15 is the same as in the embodiment previously described with reference to Fig. 1a to 1c. Here too, when the mast 12 is raised over the tarpaulin 18, the bows 15 are also pivoted up and the tarpaulin 18 is finally brought into the umbrella position shown in Fig. 4a. The bows 15 pivot about the horizontal pivot axis 19 and are pivotably mounted in the bearing supports 16a, 16b. The supporting structure with the cross members 14a, 14b corresponds to the previously described embodiment, as does the shape of the tarpaulin 18 in the stretched state, as can be seen by comparing Fig. 4b and 3b. In the embodiment according to Fig. 4a to 4c, the bows 15 swing back into a vertical position due to their own weight when the mast 12 is lowered, similar to that shown in Fig. 1a. The entire umbrella pavilion with the folded tarpaulin 18 is then in a compact form, in which it takes up approximately the space of a cuboid.
