Abstract

A wall for the booth of a coating plant is formed in the conventional manner by a sectional frame (3) composed of at least two vertical, hollow posts (4, 5) and at least two horizontal, hollow crosspieces (6, 7, 8, 9). At least one zone (10, 11, 12) which is bounded by two posts (4, 5) and two crosspieces (6, 7, 8, 9) is covered by a plate (34, 35). The corresponding plate (34, 35) is secured over the associated zone (10, 11, 12) of the frame (3) with the aid of "local" blocking devices (15 to 27) separated from one another spatially. Each of these blocking devices (15 to 27) comprises at least one retaining portion (31b, 31c) which can be inserted in a corresponding locating opening (28a, 28b, 29a, 29b) in the associated post (4, 5) or crosspiece (6, 7, 8, 9) such that a contact portion (31a) of the blocking device (15 to 27) lies against the outside of the associated post (4, 5) or crosspiece (6, 7, 8, 9). The plates (34, 35) are supported "locally" at these contact portions (31a) and are held in place in the lateral direction by a sectional frame (38) secured in a removable manner to the corresponding post (4, 5) or crosspiece (6, 7, 8, 9).

Description

a) einem Rahmen aus mindestens zwei hohlen vertikalen Pfosten und mindestens zwei hohlen horizontalen Riegeln;

b) mindestens einer Platte, welche ein von den Pfosten und den Riegeln aufgespanntes Feld überdeckt;

c) für jede Platte einer Befestigungseinrichtung, mit welcher die Platte an den das entsprechende Feld begrenzenden Pfosten und Riegeln lösbar befestigt ist.

The invention relates to a wall for the cabin of a painting system

a) a frame made up of at least two hollow vertical posts and at least two hollow horizontal bars;

b) at least one plate covering a field spanned by the posts and the transoms;

c) for each plate of a fastening device with which the plate is releasably attached to the posts and transoms delimiting the corresponding field.

Such walls can be made up of individual wall elements, the two vertical posts and a plurality include horizontal bars, be composed.

EP 0 647 476 A1 shows a wall of the aforementioned Art. With her, the fastening device includes everyone a field bordering side a profile bar that with Screws on the adjacent profile (transom or mullion) is attached. This profile bar extends over the entire length of the field and is with an undercut provided with the bevelled edge of the plate interacts. The arrangement is such that the profile bar at the same time as a positioning stop for the plate and serves as a device, which the plate on the profile holds. The required beveling of the edges however, the plates are very complex; also the design and fastening the profile strips to the transoms and Post is complicated.

The object of the present invention is a wall of the type mentioned in such a way that the fastening device for the plates a simple Has structure and easily assigned to the Posts and transoms can be set.

d) eine Mehrzahl von in gegenseitigem Abstand befindlichen Verklotzungseinrichtungen, die jeweils mindestens einen Halteabschnitt und einen Anlageabschnitt aufweisen;

e) für jeden Halteabschnitt jeder Verklotzungseinrichtung eine Aufnahmeöffnung in einem Pfosten oder Riegel,
wobei

f) jeder Halteabschnitt jeder Verklotzungseinrichtung lösbar in eine entsprechende Aufnahmeöffnung eingeführt ist, derart, daß der Anlageabschnitt an der Außenseite des zugeordneten Pfostens oder Riegels anliegt.

This object is achieved in that the fastening device comprises:

d) a plurality of spaced-apart locking devices, each having at least one holding section and one contact section;

e) a receiving opening in a post or transom for each holding section of each blocking device,
in which

f) each holding section of each blocking device is releasably inserted into a corresponding receiving opening in such a way that the contact section bears against the outside of the associated post or transom.

According to the invention, the principle is therefore abandoned Edges of the plate that are fastened in a field for correct positioning over its entire length support. Instead, a variety discrete, "local" blockers are used, each of which is only a relatively short Route along the edge of the corresponding plate extend. Each of these blocking devices leaves easily by the assigned post or Fix latch that by means of its holding section and the corresponding receiving opening on the mullion or transom a positive connection is brought about, which the blocking device holds. Assembling a plate on the frame formed by the posts and transoms is done in the following way: First, around each field in the corresponding receiving openings a suitable number of mullions and transoms Blocking devices used. the number of Blocking devices depend on the dimensions of the field. Then the plate, if necessary under Intermediate spacing blocks, simply from the side forth between the different system sections of the blocking devices be set; receives the plate hereby their correct position within the frame, but can still be moved to the side. This last one The degree of freedom of the plate is taken from the outside forth over the edge area of the plate Profile strip placed and in a suitable manner on the post or latch attached.

In general, the preferred embodiment is where each latch that is the underside of a Field limited, two blocking devices assigned to this field while the mullions and transoms, which limit this field on the other three sides, only one block device in this area exhibit. This method of construction supports the fact Bill that in the normal assembly position the wall only that which bounds the field at the bottom Latch is loaded by the weight of the plate while the blocking devices on the other three sides only the largely force-free positioning of the plate serve towards the field. The arrangement is nevertheless so stable that pre-assembly of individual Wall segments also "lying" in the way that can normally be transported vertically standing post horizontally.

The fastening device according to the invention becomes very particularly simple then when each blocker comprises a flat fixing plate, which as a holding section has at least one holding tab lying in the plane, the one formed as a slot-like elongated hole Receiving opening is insertable. Such a fixing plate can be stamped or numerically controlled Manufacture laser cuts inexpensively.

It is also useful if each fixing plate two in Has spacing holding tabs. In particular with longer fixing plates and heavier plates this way the load is evenly on the two Holding flags distributed without one of these holding flags considerable torque acts.

That embodiment is again preferred the invention, in which a slot of the side extends into each holding flag, in such a way that the corresponding fixing plate by a side Movement relative to the vertical leg of the associated Post or latch is lockable on this. After this locking movement there is a part the holding flag behind the material of the vertical leg of the corresponding post or transom so that the Holding flag no longer by train perpendicular to this Leg can be removed from the receiving opening.

If in this case the slit is pointing towards its wedge-shaped end lying within the holding flag tapered, the fixing plate in the leg of the corresponding Post or bar are really jammed, for example, by the fixing plate through lateral Blows with a hammer is moved so far until the material of the leg wedges in the slot.

FIG. 1 shows "unplaned" wall element 1, possibly together with others, left and identical wall elements adjoining the wall on the right the cabin of a paint shop.

The wall element 1 comprises in itself known Way a profile frame 3, in turn, of two lateral vertical posts 4, 5 and in the illustrated Embodiment four horizontal bars, 5, 7, 8, 9 is spanned. The posts 4, 5 and bars 6, 7, 8, 9 limited fields 10, 11, 12 are closed by plates, not shown in FIG. 1, the frame 3 in more detail below explained are attached.

Both the vertical posts 4, 5 and the horizontal bars 6, 7, 8, 9 of the profile frame 3 consist of folded steel sheet, the profile shape can be seen in Figure 3. These are around a profile whose basic geometric shape is a rectangle but that is not completely closed. The vertical profile leg 13, on which the plate (s) of the adjacent field or neighboring ones Fields is or are attached, just like one of the two adjoining legs, in FIG. 3 the lower leg 14, the full extension of the corresponding rectangle side. The on the profile leg 14 at a right angle, in FIG. 3 again upward profile leg 15 against it also extends to the top of the profile leg 13 profile legs adjoining at right angles 16 only over part of the corresponding rectangle side. This way, remains between the free ones Edges of the profile legs 15 and 16 a slit-shaped Access opening to the interior of the profile, in which certain installation elements not of interest here can be accommodated.

The slot-like access opening mentioned is through a removable cover 30 is closed. In the present Context is the exact shape of the profile from which the different posts 4, 5 and bars 6, 7, 8, 9 exist, indifferent; it is important that it is are hollow profiles that are contrary to what is shown Embodiment also closed profiles, e.g. Continuous casting profiles can be.

5 To attach the respective fields 10, 11, 12 of the frame 3 of Figure 1 covering plates are the Posts 4, 5 and the bars 6, 7, 8, 9 on the in Figure 1 places symbolically marked with circles with "local" Blocking devices 15 to 27 provided. Under A "local" blocking device becomes available understood a device that does not close like a frame around a field 10, 11, 12 of the profile frame 3 stretches around and is "local" in this sense. A typical extension of such a "local" block device parallel to the direction of the corresponding one Posts 4, 5 or bars 6, 7, 8, 9 can be in the area between 10 and 30 cm, preferably about 25 cm. Every facility is used here as a "blocking device" understood at which the in the fields 10, 11, Support 12 panels to be fastened in the lateral direction so as to face their correct position to find the elements of the frame 3. The plates can in other words, in these "blocking devices" 15 to 27 be "set" from the side and need then only one on the side facing outwards "Halt", which prevents the plates from falling out. details This "stop" will be explained below using the Figures 2 to 4 explained.

For the block devices shown in Figure 1 15 to 27 a symbolism was used, which should indicate in which direction the corresponding Blocking device is effective. This "direction of action" is in the respective circle that is the sealing device symbolizes, characterized in that a corresponding Circle segment is created black. So is about the figure 1 that the block devices 15, 16, 17, 18, 19 towards the field 10 "work". The blocking device 19 also acts additionally towards the field 11. The in the field 11 plate to be attached is also from the Blocking device 19 and beyond from the Blocking devices 20, 21, 22 and 24 supported. The Blocking device 24 in turn acts additionally in the direction of the field 12, which also the blockers 23, 25, 26 and 27 are assigned. The arrangement is such that each in a field 10, 11, 12 plate to be fastened at its lower edge by two blocking devices 15, 16 and 19, 20 or 23, 24 is supported while their other three sides each only by a block device is held. This type of "blocking" is sufficient for all positions that the wall element 1 between manufacturing in the factory and assembly on site can take: The production in the factory takes place in the general lying; the transport from the factory to Mounting position happens so that the posts 4, 5 of the Wall element 1 lie horizontally, but which of the Profile frame 3 spanned level is approximately vertical. Finally, on site, the wall element 1 in the figure 1 shown erected in which the post 4, 5 have their vertical course. apparent is in the type of block shown in Figure 1 every plate in all these possible positions adequately fixed in the profile frame 3.

The exact structure of the blocking device 19 from Figure 1 can be seen in Figures 2 to 4.

Figure 4 shows a section of the vertical Leg 13 of the bolt 7 in the area of the blocking device 19 of Figure 1. In the lower area of this Leg 13 is a first pair of slot-shaped slots 28a, 28b introduced, the individual slit-like Elongated holes 28a, 28b are aligned and with its longitudinal extension parallel to the longitudinal extension of the bolt 7 run. Similarly, the upper one Area of the leg 13 of the bolt 7 a second slot-like Slot pair 29a, 29b provided.

Each pair of slots 28a, 28b and 29a 29b is used for mounting a fixing plate, as in Figure 2 in side view shown and there with the reference number 31 is marked. The fixing plate 31 is a flat sheet metal blank that is made by punching or laser cutting can be made. It includes a strip-shaped contact portion 31a, which is extends over the entire length of the fixing plate 31, and two molded onto the ends of the contact section 31a rectangular holding tabs 31b and 31c. The two holding flags 31b and 31c are substantially rectangular Recess 31d separated from each other. From the bottom of the recess 31d, a limitation of the contact section 31a forming a wedge-shaped slot 32 into the holding tab 31b, but passes through it not completely. The same goes from the right End of the fixing plate 31, in the geometric extension the bottom of the recess 31d, a second wedge-shaped slot 33 in the right holding tab 31c without fully enforcing it.

The fixing plate 31 shown in Figure 2 can be in one of the two elongated hole pairs 28a, 28b and. 29a, 29b obviously fix in the following way: First the holding tabs 31b and 31c become both a pair of elongated holes 28a, 28b and 29a, 29b introduced (the width of the holding tabs 31b and 31c corresponds to the length of the elongated holes 28a, 28b and 29a, 29b; the distance between adjacent elongated holes 28a, 28b or 29a, 29b in the pair corresponds to the width of the Recess 31d of the fixing plate 31). If the reason of the Recess 31d of the fixing plate 31 on the surface of the Thighs 13 abuts, the slots 32, 33 of the Fixer sheet 31 with the sheet material from which the Leg 13 of the bolt 7. The fixing plate 31 can now, if necessary, with the help a hammer, are driven aside so that the between the elongated holes 28a, 28b and 29a, 29b Material area of the leg 13 penetrates into the slot 32 and correspondingly one next to the elongated holes 28b, 29b lying material area of the leg 13 in the Slot 33 penetrates. Due to the wedge-shaped design the slots 32 and 33 jam the Fixing plate 31 in the position shown in Figure 3. The holding section 31a projects in each case outwards over the leg 13 of the bolt 7, while the holding tabs 31b, 31c inside the hollow Extend profile from which the bolt 7 is formed.

The blocking device shown in Figure 3 As already explained above, 19 acts in two directions. That is why she is in the upper pair of slots 29a, 29b and in the lower pair of elongated holes 28a, 28b a fixing plate 31 is inserted in each case. Corresponding is also the blocking device 24 in the bolt 8 of the profile frame 3 (see FIG. 1).

For all other blocking devices 16 to 18 and 20 to 23 and 25 to 27, however, becomes only one Fixing plate 31 used, which in that pair of slots 28a, 28b or 29a, 29b is introduced, which to of the plate to be fastened. Basically it would be in these latter blocking devices 15 to 18 and 20 to 27 also possible in the corresponding Frame part 4 to 9 also only a single pair of slots 28a, 28b or 29a, 29b to be provided.

As FIG. 3 further shows, the contact area 31a serves the fixing plates introduced in the leg 13 of the bolt 7 31 the support of the plates, which on the the bars 7 adjacent fields 10, 11 are attached should. For illustration purposes, FIG assumed that the field 10 below the bar 7th is covered by a metal plate 34 while the Coverage of the field located above bolt 7 11 takes place through a glass plate 35. The edge of this Plates 34 and 35 are not immediately but over a block 36 or 37 of the appropriate material on the corresponding contact section 31a of the associated fixing plate 31 at.

As already mentioned above, the plates 34 and 35 after inserting between the various blocking devices another side hold. This is shown in the embodiment of FIG a double-acting holding profile 38 ensures which overlaps both the metal plate 34 and the glass 35 and with the help of hammer head screws 39 and corresponding Nuts 40 on the leg 13 of the bolt 7 is attached. The space between the leg 13, the Blocks 36 and 37 and the overarching areas of Retaining profile 38 is each with an elastic Sealing material 41 filled in such that the neighboring Edge areas of the plates 34 and 35 in this sealant 41 are embedded.
