Description

The invention relates to a step element on a cheek a grandstand construction is releasably attachable and that is formed from a step and a riser.

Such a step element is, for example, by Arena Seating company became known.

To attach the step elements are on the cheeks of the grandstand construction both on one cheek side and on of the diametrical cheek side fastening means provided.

Standing dog extended at venues or in halls Being able to offer seating is portable Known stages that consist of a variety of items and their assembly and / or dismantling is time-consuming. This even more so than each step element individually using fasteners must be connected to the cheeks.

The invention has for its object the above To further develop the step element in such a way that a simple one and quick construction of a safe grandstand construction is achieved.

The object is achieved in that at least a free end of a step element a profile end or has a peg that is in a recess, in particular an opening, the cheek insertable is.

The step element is immovable in the horizontal direction connected to the cheek. Through the cutouts on the cheek the position of the step element can be determined. about the profile ends or the pins are fixed in position on the cheek. The step elements are also oriented, making it easier to build a grandstand.

In a particularly preferred embodiment, the profile end or the pin of adjacent step elements at least side by side in the recess, in particular Breakthrough opening, the cheek insertable. Through this Measure can be applied to one side of the cheek Step elements are used. For both step elements only one opening is required on a cheek. Thanks to this measure, cheeks can be saved because only one cheek for step elements arranged side by side necessary is. There is also a simplified alignment lined up step elements.

If consecutive profile ends of contiguous Step elements the recess, in particular the Breakthrough opening, reach behind, are the risers in the used state in the vertical direction immovable with connected to the cheek securely positioned. This way and Way becomes a self-locking bracket of the step element realized particularly easily on the cheek. If the step element holding itself on the cheek, are not additional fastening means for fastening the step element with the cheek necessary. Because of the immovable Bracket, the step element is held on the cheek so that the dismantling can only take place in predetermined steps and held the step element against vandalism on the cheek is. At least one of the profile ends preferably projects an immediately adjacent step or riser into the hollow profile of the individual cheek and holds even securely immovable on the cheek. This has the advantage that through the imperative sequence of those to be built Elements need not be worked across abysses, when the treads and risers are placed on the cheeks become. Furthermore, a safe construction of the grandstand is always guaranteed because the reviews for hedging and Security of one with the step elements according to the invention built grandstand can be omitted.

In a further embodiment of the invention, the step element an articulated head and an articular socket, the Rod end of a first step element in the socket of an adjacent second step element comes to rest and the joint head of another adjacent third step element in the socket of the first step element comes to lie. Through this measure, on the one hand, the structure relieved the bleachers and, on the other hand, vandal-proof Connection of two adjacent step elements created. Both the joint head and socket joint Training can span the entire length of a course Extend step element.

In a preferred development is on the socket a projection is formed, which has a recess on the joint head of an adjacent step element or locked with this. This creates one in the built Condition of the grandstand permanent connection between two in a row adjacent step elements.

It is particularly preferred if at a free end of the A safety element, in particular a step element Pawl, which is an edge projection of the cheek engages behind, in particular engages behind automatically. By the securing element becomes captive of the step element and immovably attached to the cheek. By that Securing element automatically engages behind the edge projection, are no further steps during assembly Fastening of the step element necessary. Because of the immovable Bracket is the step element on the cheek held that the dismantling only take place in predetermined steps can and the step element vandalism-proof on the Cheek is held. In addition, the order of the grandstand construction established. Again, this has the advantage that due to the mandatory sequence of the elements to be built must be worked across abysses when the step and Risers can be arranged on the cheeks.

In an advantageous development, the securing element is especially the pawl, through an adjacent step element in the position engaging behind the edge projection held. This means that no more stops or Locking means are necessary to secure the element to hold in the back position. When dismantling the grandstand is removed by removing the adjacent step element the securing element released again, so that when loosening the associated with the securing element Step element automatically pivoted into a release position.

In a preferred embodiment the is at the free end Treading a final profile, being on the final profile a receiving pocket is provided in the one adjacent step element engages releasably. Through this Measure will be the assembly of an adjacent step element facilitated.

This can increase the safety of the grandstand construction be that the final profile is a contact surface for flat Has plant on the cheek.

If a hook-shaped training is provided on the end profile is that of the riser of an adjacent step element is in the raised state, it is possible to swivel the riser clockwise so that it can be taken out of the pocket. This will make it easier to dismantle the grandstand.

It is particularly preferred if the step and the Riser of the step element releasably connected to each other are, they only by a pivoting movement are releasable and connectable to each other. advantageously, it is thus possible to use steps with risers to combine different heights. Still is it is not possible with the step element installed, i.e. at vertically aligned riser and horizontally aligned riser Step, riser and step from each other separate. As a result, the step element is vandal-proof educated. Are the riser and the tread one Step element detachable from each other, so they can be used as individual parts can be stored and transported to save space.

If the step elements are made up of risers and steps, the treads regardless of the inclination of a cheek have the same tread depth to the horizontal and are at the edge of the steps that are adjacent to the risers, Openings are provided for receiving the structural elements, this further simplifies the grandstand system. The same steps are used for every angular position of a cheek inserted and there are openings on the step elements intended for seating seats or railing structures. The seats or railings must be in the designated areas Openings are inserted and are in the openings held self-locking. The risers can be also simplify when collapsible in height are and therefore in the simplest of different angular positions the cheeks can be adjusted. The foldable section to extend a riser can use the step and / or be articulated to the riser itself. For different angular positions of the cheeks are different high risers provided. For example, cheeks become one Length of 2.50 m for the construction of a grandstand on a Substructure with 50 cm height grid and are used the step elements are attached to the cheeks according to the invention, for example, for different Angular positions of 0 °, approx. 11 ° and approx. 22 ° steps with a Use a step depth of 75 cm and the risers have a height of approx. 11 ° with an angular position of the cheeks of 15 cm and with an angular position of the cheeks of approx. 22 ° a height of 30 cm.

If railing posts are attached to the step elements, so can these railing posts in cavities of the kick and / or Risers are inserted and another fixation and / or can secure the railing posts by there is an intervention in the openings in the cheeks. The steps and risers can also be in one piece be formed so that a step element from a single Element is formed.

Further advantages result from the description and the attached drawing. Likewise, the above and the features listed further according to the invention individually or in any combination with each other be used. The mentioned embodiments are not to be understood as a final list, but to have rather exemplary character.

Fig. 1 shows a partial section of a grandstand construction in a spatial representation with step elements 31, which are composed of steps 32 and risers 33. The step elements 31 can be detachably attached to the cheeks 11, 12, 13 by profile ends of the step elements 31 engaging in through openings 34 in the cheeks 11, 12, 13, which are formed on a cheek side 35, 36, 37. The through openings 34 formed on the cheek side 35, 36, 37 are spaced apart from one another such that treads 32 with the same tread depth can be fastened in or on the through openings 34 regardless of the angular position of the individual cheeks 11, and a first step element always in first pickup point is attached. The telescopic parts 14, 15 have a mandrel 38 which can likewise engage in the through openings 34 and with which the length of the telescopic part 14, 15 to be staked out can be determined. In Fig. 1, a telescopic head 39 of the first telescopic part 14 can still be partially recognized. The first cheek 11 is connected to the second cheek 12 via the telescopic head 39. The substructure, not shown in FIG. 1, holds the cheeks 11, 12 and 13 via the receiving heads 19.

In the transition area between a step 32 to the riser 33 a series of openings 40 are provided, the Building elements such as seats and railings can accommodate.

Fig. 2 shows the transition area of a first cheek 11 to second cheek 12, partly in section, so that profile ends 41, 42 of the steps and risers 32, 33 can be seen. The profile end 41 of the end profile of the step 32 reaches through one of the openings 34 and engages behind the first cheek 11 with the free end Profile end 42 of riser 33 also engages in the Breakthrough opening 34 and is designed so that it is in Interaction with the profile end 41 a vertical displacement blocked or prevented by step and riser 32, 33. The numerous trained in the first cheek 11 Breakthrough openings 34 are provided for the step elements 31, if the cheeks 11, 12 in different angular positions be set up. With the mandrel 38 reaches through first telescopic part 14 has an opening 34 and supports one end over the telescopic head 39 on the second cheek 12 from. On the telescopic head 39 there is also the safety catch 43 provided the connection between the first Telescopic part 14 and the second cheek 12 secures. At the other end the first telescopic part 14 is supported by a support plate 44 on the inner surface of the first cheek 11 from.

If a substructure with cheeks 11 attached to it, 12 erected and have the cheeks 11, 12 attachment points like the breakthrough openings shown in FIG. 2 34 on, the steps and risers 32, 33 in one Way to be attached to the cheeks 11, 12, for which none Auxiliary structures or additional resources are required. The tread 32 is in the direction of arrow 45 on the placed the second cheek 12 by pivoting the step 32 so that the profile end 41 into the opening 34 engage and reach behind this opening 34 can. If the step 32 is laid, the riser can 33 pivoting in the direction of arrow 46 into the opening 34 are used. The riser 33 is vertical aligned, and grip the profile ends 41, 42, as in the Figure shown in the opening 34, and is the Step 32 with riser 33 by the mutual Engagement hooked, so are the step 32 and the riser 33 firmly and permanently connected to the second cheek 12. If the riser 33 is to be detached from the second cheek 12, the riser 33 must go in the opposite direction of the arrow 46 are pivoted so far that the profile end 42 from the Breakthrough opening 34 can be removed. Is the Riser 33 removed from the opening 34, so can also the step 32 via a movement of the step 32 detached from the second cheek 12 against the direction of the arrow 45 become.

Should a further vertically aligned riser 33 Step 32 are put on, this is the step 32 via a pivoting in the direction of arrow 47 to the riser 33 hang up. When placed on riser 33 nubs and noses reach behind the end of the step the riser 33 such that the step 32 with the Riser 33 is inextricably linked. The step 32 can from riser 33 only by moving against the Arrow direction 47 can be solved. The one for a step element 31 described assembly and disassembly of the steps and risers 32 and 33 can be arbitrarily attached to a step element 31 Transfer step element so that with the described Erection and dismantling of steps and risers 32, 33 any tall and long grandstand constructions can be created can.

3 shows that the step 32 and the riser 33 in the second cheek 12 are used to secure themselves. A projection 50 is formed on the riser 33, the receive openings 40 as shown in FIG. 1 can.

If the step 32 is allied with the riser 33, so is a joint head 27 formed on the riser 33 in a joint socket 28, which in the edge region of the step 32nd is formed. Both the joint head-shaped and the socket-shaped training can extend over the entire Length of a step and / or riser 32, 33 extend. On on the joint socket 28 formed projection 29 engages behind or locked with a recess 30 on the joint head 27 of riser 33, making an inseparable connection between tread and riser 32, 33 arises. Should the connection between the step and riser 32, 33 in the lower Area, that is, in the area of the cheek, to be solved, so the joint head 27 must first extend so far from one overarching or engaging engagement in the socket 28 is unscrewed or be moved until the two parts are apart can be separated.

The first cheek 11 is connected to a second cheek 12 via the telescopic part 14. On the cheek 12, which is held in its horizontally aligned position by a receiving head 19, there is a step 62 which is detachably connected to a riser 63. At the upper end of the riser 63, a further step 62 is held, the other end of which rests flat on the inclined cheek 11. At this end there is again a riser 63, which has the same connection to the step 62 as shown in the right part of FIG. 4.

The cheek 12 has an opening 64 through which a pin 65 of an end profile of the step 62 engages. The end profile of step 62 has one Pawl 66, which engages behind an edge projection of the cheek 12 and the step 62 cannot be lost with the cheek 12 combines. At the end profile of step 62 is the A receiving pocket 67 is formed opposite the pin 65, in the lower end profile of riser 63 releasable intervenes. At the top of riser 63 is another End profile formed with a recess 68, that holds a free end of step 62 that doesn't open a cheek 11, 12 rests.

Should a step element be placed on a cheek connection are, the step 62 is first on the horizontal aligned cheek 12 placed by the pin 65 in the opening 64 is inserted. With this insertion movement automatically engages behind one end of the pawl 66 a free edge of the cheek 12. Should now be a riser 63 inserted into the receiving pocket 67 of the step 62 , the riser 63 is inclined to the end of the Step 62 is set by the set step 62 with the riser 63 encloses an angle <90 °. Subsequently the riser 63 is so far above the step 62 pushed out that riser 63 in the receiving pocket 67 falls. In the inclined position of the Riser 63, riser 63 is raised and simultaneously counterclockwise in the direction of arrow 69 vertical aligned. Then the riser 63 is lowered, and it is then in the position shown in FIG the receiving pocket 67 held. Should at the top of the Riser 63 another step 62 to riser 63 be tied, a step 62 is aligned vertically inserted into the recess 68 and then counterclockwise lowered in the direction of arrow 70 so far until the other free end of step 62 with the Pin 65 in the opening 64 of the inclined Cheek 11 engages. The final profile of the step 62 is designed so that it is oriented at an incline Cheek 11 can lie flat.

A riser 63 is inserted into the receiving pocket 67 and aligned vertically, it blocks the swivel range the pawl 66 and holds the pawl 66 such that a free end of the pawl 66 always a free edge section the cheek 11, 12 engages behind. In the shown in Fig. 4 Arrangement are the steps 62 from the cheeks 11, 12 cannot be withdrawn.

Should a step element of one shown in FIG. 4 The riser must first be lifted off the riser 63 in the receiving pocket 67 are raised so far that it is rotated clockwise out of the receiving pocket 67 can be. Is the connection between the step 62 and riser 63 interrupted by the receiving pocket 67 is free, so the pawl 66 is pivotable movable, and the step 62 can from the cheek 11, 12 can be lifted off. When lifting step 62 opens the pawl 66 automatically, i.e. it indicates the rear grip cheek 11, 12 free.

Fig. 5 shows the cheek connection of the cheeks 11 and 12 with a cut cheek 12, like the two cheeks 11 and 12 are connected to one another via the telescopic part 14. The step 62 is placed on the cheek 12 by the Pin 65 engages in the opening 64 of the cheek 12. The end profile of the step 62 is via the pawl 66th held captively with the cheek 12. In the pocket 67 of the final profile of step 62 is a End of riser 63 used. The riser 63 is vertical aligned, and the receiving pocket 67 is formed that in the inserted state of a riser 63 has a free space that allows the vertical aligned riser 63 in the receiving pocket 67 raised can be. If riser 63 is raised, so it engages behind a hook-shaped formation on the end profile the step 62, and in the raised state the Riser 63 it is possible to increase riser 63 clockwise to pivot so that it comes out of the receiving pocket 67 can be removed. The riser 63 is in the receiving pocket 67 used vertically aligned, so the Jack 66 can not be moved and connects the inseparable Step 62 with cheek 12 or cheek 11.

Fig. 6 shows a perspective view of a shortened and horizontally aligned cheek 12 on one Step 62 is put on. The step 62 is in the Fig. 6 is not shown in the entire width dimension. Basically, a step 62 has in each free end area two opposing support points with pegs 65, each on through openings 64 of a cheek 12 intervene. Only one cheek 12 is shown in FIG. 6. Via the pin 65, the step 62 engages in the Breakthrough opening 64, and the step 62 on placed on the cheek 12, one end engages behind the pawl 66 a free edge portion of the cheek 12. The pawl 66 is pivotally attached to the step 62 about an axis 71. The receiving pockets 67 are indicated in the figure, can engage in the ends of risers 63. Will the Step 62 is lifted from the cheek 12, so pivoted the pawl 66 automatically by pulling on the rear grip the cheek 12 releases. The step 62 can always from the Cheek 12 can be lifted when the receiving pocket 67 is not is occupied by a riser.

Fig. 7 shows in a sectional view, like a step 62 rests on a cheek 12. The pin 65 of the Step 62 engages in the opening 64 of the cheek 12, and the pawl 66 engages behind a free edge portion the cheek 12 by moving around the axis 71 accordingly twisted.

Fig. 8 shows a rear view, like a step 62 and a riser 63 on one side on one cheek 12 rests. The pawl 66 engages behind a free edge section the cheek 12, and in the arrangement shown the step 62 cannot be lifted off the cheek 12.
