Description

The invention relates to a support frame for a plate, in particular a beer bench or a beer table, which is formed from carrier profiles which comprise legs.

Beer benches and beer tables of the prior art regularly consist of a wooden tabletop, arranged on often painted metal legs. The beer benches are usually made in the same design as the beer tables. An embodiment of such beer tables or beer benches results for example from the DE 20 2012 008 398 U1 whose innovation lies in the fact that the feet are put over the existing legs of the beer banks. This increases the contact surface of the legs on the ground. The legs are additionally protected against damage by the material of the soil such as sand, earth, stones or concrete.

Beer tents or beer garden sets known from the prior art, ie beer tables and beer benches, are often equipped with two carrying racks, each carrying rack having at least two longitudinal bars. The longitudinal spar is designed as a carrier profile, and as a rule has two limbs connected to one another and arranged at a right angle to one another. A leg of the longitudinal spar extends generally transverse to the longitudinal axis of the table top. The carrier profiles can be produced by forming, extrusion or by rolling. They are usually made of metal. The legs have the same leg width (isosceles).

In the known carrier profiles whose legs each have a width of about 30 mm, so they are the same length. The leg thickness usually varies from 2, 7 to 3 mm. Thicknesses of less than 3mm lead to noticeable instability. Thicknesses below 2.69 mm are particularly unstable.

However, such thigh dimensions lead to increased material consumption, which has a negative effect on the production costs and the weight of the beer table or the beer bench Since beer benches and / or beer tables frequently and in large numbers up and dismantled and to the construction staff or by the visitors be carried and stacked, a high weight of beer tent sets proves to be extremely disadvantageous.

At folk festivals it happens that the Valksfest visitors stand in the beer tents on the plate of the beer table or on the plate of the beer bench and dance there exuberantly. The forces acting on the longitudinal bars in this case typically run in the longitudinal direction of the bank or plate, i. towards their ends. The beer bench or the beer table learns by the dancing on her / him visitors a pivoting movement in the longitudinal direction of the table or the seat plate. The pivotal movements are along the longitudinal axis of the plate of the beer table or the beer bank in opposite directions. Therefore, it is assumed in the following of a pivoting movement in the longitudinal direction of the table top or seat plate.

Due to the pivoting movement in the direction of the longitudinal axis of the plate of the beer bench or the beer table those legs of the support profile of the support frame, which are parallel to the longitudinal axis of the plate exposed to a special load. This often happens where support bracket is attached to the carrier profile.

The invention therefore has as its object to provide a support frame for a plate, in particular a beer bench or a beer table, which has sufficient stability to be able to cope with the burden of visitors dancing on the beer bench or on the beer table. At the same time it is the object of the invention to provide a support frame, which requires compared to support frames from the prior art with wall thicknesses of 2.7 to 3 mm and at least the same stability with less material consumption and thus has a lower weight and cheaper to produce is.

The object is solved by the features of patent claim 1.

The invention provides a support frame for a plate, in particular a beer bench or a beer table ready, which is formed from at least two carrier profiles, each forming a longitudinal spar and include the legs, each having an equal or different wall thickness. The carrier profiles comprise in cross-section at least two outer legs arranged on a central leg, wherein the width of one outer leg is smaller than the width of the other outer leg and wherein the carrier profiles are C-shaped and interconnected by at least one transverse connection. Two beer benches and a beer table are combined in a so-called beer tent set. The beer table or the beer bench has a wooden tabletop or seat plate and each has two collapsible metal carrying racks. The table top can take any measure. Typical dimensions are for example 220 cm x 50 cm, but also 220 cm x 80 cm. The plate can also consist of other materials, eg Plastic or metal. The carrying racks of the beer table or the beer bench can be folded flat and fixed in open or folded position.

The beer bench includes a seat plate made of wood or other materials and can be produced in all dimensions. If a beer table is usually 77 cm high, the bench height of the beer bench measures approximately 47 cm. The carrying racks of the beer bench can also be folded in and fixed in the open or folded position.

Beer sets are made as a mass product or serial goods identical and therefore easy to stack and transport. The beer table and the beer bench are also robust. To position the beer table and / or the beer bench on a solid surface, the beer table and the beer bench have a carrying frame that is made of carrier profiles.

The carrier profiles may be arranged parallel to each other longitudinal bars that determine the seat height and the height of the beer table. According to the invention, the at least two carrier profiles each form a longitudinal spar. According to the invention, the longitudinal beams are connected to one another by connecting profiles (referred to below as cross connections), wherein the transverse connections can run horizontally, transversely to the longitudinal direction of the plate. Depending on the embodiment of the support frame, the cross member may be arranged on the plate-side end of the longitudinal members. In addition, the cross-connection can connect the longitudinal spars approximately in the middle of each other. The cross-connection may further comprise at least one diagonal, preferably arranged in the upper third of the support frame, e.g. X-shaped carrier. The cross-connection may also be a cross member, which is formed as an additional footprint, which connects the longitudinal beams at their bottom end faces together. These cross connections can be present together, but also in any combination. The cross-connection (s) may (may) as a round or square tube profile, as a flat sheet with or without stiffening elements, such as beads, beads, ribs, waves, may be formed.

To stiffen the support frame so diagonal support can be arranged, which connect the two longitudinal beams at different heights together. The diagonal brackets can be arranged in pairs on the support frame and touch between the longitudinal beams and secured together. Furthermore, the carrier can also extend approximately at an angle of 90 ° to the longitudinal beams and for about a piece comprise instead of bevels.

To lock the support frame relative to the table top of the beer table or the seat plate of the beer bench, a support bracket may be provided. The support bracket may be in the form of an isosceles triangle and pivotally hinged to the longitudinal beams. The support bracket may be formed as a round or square tube profile, as a flat sheet with or without Verstungs elements, such as beads, beads, ribs, waves. It may for example consist of trapezoidal in the direction of the bottom mutually extending flat sheet metal profiles, which are connected at their tapered ends with a bolt, tube or in any configuration with each other. Of course, the support bracket may be fully or partially arcuate, omega-shaped, waisted or have any geometric shapes.

The support bracket is pivotable relative to the support frame and can be locked to a arranged on the underside of the table top or the seat lock on the table top or on the seat plate. The lock can be done on the one hand in a vertical position of the support frame against the beer bench or the beer table. However, the locking can also be done so that the support frame for stacking the beer benches or beer tables abutting each other on the underside of the table top or the plate of the beer bench. The carrier profile may comprise a support bracket which extends in the plane of the support frame and is arranged laterally outside of the longitudinal beams of the support frame. The design of the support bracket may be V-shaped and serve the additional support the support frame in the transverse direction. The support bracket prevents the beer table or the beer bench from tipping over in the lateral direction.

The arrangement of a support bracket lends itself especially to the beer bench when it is provided with a backrest. The same applies to beer tables with a larger width of the table top. The support bracket can be arranged on one or both support profiles.

The support frame may have a rectangular basic shape. Preferably, the support frame to further increase the stability of a trapezoidal shape.

The support frame is formed from carrier profiles which include legs. According to the carrier profiles of the support frame are designed as C-profiles. The carrier profile has three legs, of which a left and a right outer leg are arranged on a central leg. The outer legs are arranged at an angle, preferably 90 °, to the middle leg. The outer legs preferably differ in width from each other and from the middle leg.

As legs in the context of the invention not only flat sheets are understood. They can also be bent or, for example, wavy. In this case, the legs are connected to each other via rounded "angles". Even such rounded "angles" are angles in the sense of the invention.

In terms of their wall thickness, the legs preferably do not differ when they are produced by way of material deformation. When made by, for example, extrusion or rolling, the wall thickness of the legs may also be different. The middle leg of the carrier profile may extend approximately parallel to the longitudinal axis of the table top or the seat plate of the beer bench. According to the invention, the width of one outer leg is less than the width of the other outer leg. The smaller leg width can assume any value that is smaller than the value of the larger leg width. The leg width extends approximately at a right angle to the leg length.

The wall thickness of the legs is compared to the wall thickness of about 3 mm used in the prior art in the embodiment according to the invention significantly less executable without this would have an impact on the stability of the frame. The legs can have different lengths (widths). The middle leg is preferably the widest of all three legs.

The maintenance or even increase in stability is accomplished according to the invention that despite the preferred shortening of the width of the outer leg compared to the width of the middle leg, a further outer and preferably shorter leg is present, resulting in the C-profile. This construction allows a reduction in the wall thickness of the material compared to the prior art. In this way, a material saving can be effected.
The smaller wall thickness may preferably have a value of less than 3 mm to 1.5 mm, but preferably about 2 mm.
The one outer leg preferably has a smaller width in comparison to the middle leg and can, for. B. 20 - be 27 mm wide. The middle leg is preferably about 30 - 38 mm wide. Both legs then have an unequal leg angle. This one outer leg and the middle leg can also be made the same width. The smaller outer leg has a dimension of preferably 5 - 15 mm, particularly preferably 8 mm.

The stated information on the wall thickness and the width of the legs are purely exemplary and in no way exclusively meant. Other values can be set in the same way,

The formation of the carrier profiles as a C-profile gives the carrier profiles of the support frame additional stability, so that a lower material thickness is made possible in comparison to that of the prior art. As a C-profile according to the invention, such an embodiment is referred to, in which one or both ends of the / the outer leg (s) are bent at an angle or in an arc shape to the inside or outside. As a result, the stability increases even more, so that an even smaller wall thickness can be used as indicated below. Also, the middle leg can be designed arcuate. The limb (s) may instead or additionally be profiled and be wavy and / or have ribs and / or beads and / or beads and / or other stability enhancing limb geometries.

The invention proves to be advantageous because the support frame due to the shortened width of one of the legs undergoes a material saving and a weight reduction. The stability of the carrier profile and thus also of the support frame remains in particular on carrier profiles transversely to the longitudinal axis of the table top or the seat plate thereby ensured that the leg width of the particularly stressed middle leg is increased compared to the leg width of the outer leg. The stability of the support profile of the support frame is additionally increased by the fact that the support profile has legs which are connected to each other and are arranged angled to each other and form a C-profile.

To increase the stability of the support frame and to optimize the flow of force within the legs of the carrier profiles, the support frame may be formed in a trapezoidal shape.

The legs 3; 4 and 5 can each have the same wall thickness 6 in all subsequent figure representations. However, they may also have different wall thicknesses 6, in particular if the carrier profiles 2 have been produced by means of extrusion or in a rolling process.

Fig. 1 shows a support section 2 with two longitudinal beams 8 of a support frame 1. The support frame 1 has a lower cross member 9, which is connected to the longitudinal bars 8 approximately at right angles. The lower cross member 9 has an opening 15, which serves the drain of rainwater, whereby possible corrosion is prevented. In the outermost corner region of the cross member 9, a projection 16 can be seen, which also has an opening 15 and increases the stability of the support frame 1 in particular on an uneven floor 18.

On the side facing away from the cross member 9 of the longitudinal beam 8, a support bracket 12 is shown, which prevents a lateral overturning of the support frame 1. The support bracket 12 extends in the plane of the support frame 1. As a result, the stability and tipping security are increased in particular of beer benches with backrests. The same applies to beer tables with a larger width of the table top. At the longitudinal members 2; 8, a middle leg 3 can be seen, which is connected to a left outer leg 4 and a right outer leg 5. The width of the leg 4 is greater than the width of the leg 5 of the carrier profile. 2

The longitudinal spar 2; 8 is formed as a C-profile 13, wherein the C-profile 13 has a leg 4 with a larger width and a leg 5 with a shortened relative to the leg 4 width. The leg 5 may preferably have a width of 8 mm and the legs 4 preferably have a width of 25 mm; But the C-profile 13 may also have a profile with equal legs.

The lower cross member 9 has in the same way a carrier profile 2 with a middle leg 3 and outer legs 4; 5. At the lower cross member 9, the width of the leg 4 is greater than the width of the leg. 5
