Description

Field of the invention



[0001] The invention relates to a painting suspension arrangement, which is used for suspending an object or objects to be painted for painting. A painting suspension arrangement is used in spray painting.

Prior art



[0002] An object or objects to be painted is commonly suspended on a suspension device, which is made for this purpose. Several objects to be painted are usually suspended on the same suspension device, whereby many objects can be painted at the same time. Known suspension devices are made of thick metal wire or a metal rod by welding. The painting suspension device is such that the paint spray can be directed so that the paint reaches all the surfaces to be painted on the object. Between the objects to be painted, there must be sufficient space for the paint spray. For this reason, the painting suspension device takes up a relatively large amount of space.

[0003] Painting suspension arrangements are usually made of metal, and they are grounded, so that the paint spray sticks better to the surface of the object to be painted. When the painting suspension arrangement has been used sufficiently many times, the grounding properties may have been remarkably deteriorated by paint, which has accrued on the surface of the painting suspension arrangement. This is in the end also seen in the quality of the painting of the objects to be painted. The used painting suspension device is at the end exchanged for a new painting suspension device.

[0004] Because the painting suspension arrangement requires, due to its structure, a lot of space (usually a frame-like structure formed from various shafts), it requires a relatively large amount of storage space and transport space for example in trucks and vans. This affects the storing costs and transport costs.

Brief description of the invention



[0005] The object of the invention is to eliminate disadvantages of prior art. This is achieved in the manner presented in the independent claim. The dependent claims present different embodiments of the invention. The invention is based on the painting suspension arrangement consisting of parts which can be combined together, whereby it takes up less space in storage and transport. Additionally, the whole painting suspension arrangement does not need to be exchanged after it has been used many times. It is sufficient that only parts of the painting suspension arrangement are exchanged.

[0006] The painting suspension arrangement according to the invention is made for suspending objects to be painted, and it comprises a suspension rail 1, 12, the first end 2, 2A of which has a hook arrangement 3,13 for hanging the suspension rail. The shaft part 4 and the area 5 of the second end of the suspension rail comprise holes 6, and the suspension rail is a rail folded from a metal sheet, which rail has at least one fold 7, 7A in the longitudinal direction of the rail. The painting suspension arrangement additionally comprises a horizontal suspension arrangement 8, which is arranged to be connected to the holes 6 of the suspension rail, and it comprises horizontal rails 9, 14, 15, 18 and suspension protrusions 10, 16, 17, 19. The horizontal rails are rails folded from a metal sheet, which rails have at least one fold in the longitudinal direction of the rail.

[0007] The horizontal suspension arrangement comprises two diagonal support rails 36 and a horizontal support rail 37, which are arranged to be installed in connection to the suspension rail 1 by using the holes 6 of the suspension rail, and which diagonal support rails 36 and horizontal support rail 37 are arranged to form an equilateral triangle in connection with the suspension rail 1, both ends 37A, 37B of the horizontal support rail 37 being arranged to be connected to the ends (36B) of the diagonal support rails.

[0008] The horizontal suspension arrangement additionally comprises two side rails 38, which are arranged to be connected by their first ends (38A) close to the ends K1, K2 of said triangle, which ends are formed from the connecting angles of the diagonal support rails 36 and horizontal support rail 37, and which horizontal rails 9 are arranged to be connected by both ends to the side rails 38.

Description of the invention



[0010] Figure 1 shows an example of a painting suspension arrangement according to the invention. The painting suspension arrangement according to the invention is made for suspending objects to be painted, and it comprises a suspension rail 1, 12, the first end 2, 2A of which has a hook arrangement 3, 13 for hanging the suspension rail. The suspension rail is suspended for example from a hook or rod attached to the ceiling of a painting hall.

[0011] The shaft part 4 and the area 5 of the second end of the suspension rail comprise holes 6. The suspension rail is a rail folded from a metal sheet, which rail has at least one fold 7, 7A in the longitudinal direction of the rail. Thus, rigidity is achieved in the suspension rail, while the structure is still relatively light. One longitudinal fold is sufficient in many applications, but the sturdiness and rigidity is better, if two or more folds in the longitudinal direction of the rail are used. Figures 2, 3, 23, 24 and 25 show examples of embodiments of the suspension rail.

[0012] The painting suspension arrangement additionally comprises a horizontal suspension arrangement 8, which is arranged to be combined / attached to the holes 6 of the suspension rail, and it comprises horizontal rails 9, 14, 15, 18 and suspension protrusions 10, 16, 17, 19. The horizontal rails are rails folded from a metal sheet, which rails have at least one fold in the longitudinal direction of the rail. Sturdiness and rigidity is achieved with the longitudinal fold or several longitudinal folds also in the horizontal rails.

[0013] In the embodiment of figure 1 can be seen that the suspension protrusions 10, 16 are arranged to be connected to the horizontal rails 20, 14, or otherwise the suspension protrusions 19 are fixed parts of the horizontal rails 15. The suspension protrusions can thus be separate parts, which are connected to the horizontal rails. The horizontal rails 9, 14, 18, 23, 26 have holes 20, 21, 22, 24, 25, 27 for connecting separate suspension protrusions 10, 16.

[0014] Depending on how the paint spray is controlled and how the object/objects to be painted is suspended, paint is accrued on the suspension protrusions, the horizontal rails and possibly also on other parts. After several painting times, the paint accrued on the parts impairs the grounding of the objects to be painted via the suspension arrangement. Thus, in known solutions, the whole painting suspension device would have to be exchanged, but in the implementation according to the invention it may be enough that only some parts are exchanged for new parts, such as suspension protrusion and additionally also some horizontal rails.

[0015] Figure 13 shows an example of a suspension protrusion 10, which is a plate part. Its middle area 28 has attaching surfaces 29 for connecting to the horizontal rail 9. The attaching surfaces 29 are surfaces of grooves formed in the plate (in this embodiment grooves shaped as a letter j), which surfaces are connected to holes 20 in the horizontal rails 9. Both ends of the plate part, which is elongated, have a protrusion 30 for suspending an object to be painted.

[0016] Figures 18 and 19 show a second embodiment of the suspension protrusion 16, which comprises a shaft 31. Its first end 32 has an arrow shape 34 and its second end 33 has a narrowing area 35 of the shaft. The narrowing area helps and steadies the connecting and coupling of the suspension protrusion to the horizontal rail. Some of the holes of the horizontal rail can be larger, allowing the pushing of the shaft of the suspension protrusion into it (i.e., not just by the narrowing area). Other holes in the horizontal rail can be smaller, allowing only the narrowing area 35 to be pushed through the hole. Thus, the suspension protrusion installer knows when the suspension protrusion is properly installed, when the suspension protrusion 16 cannot be pushed deeper.

[0017] From the embodiments of the figures can be observed that the area 4A of the shaft part of the suspension rail 1, 12, which area is beside the first end 2, 2A and the hook arrangement 3, 13, is without holes. This is appropriate, because it is not desired for the objects to be painted to be very near the ceiling of the painting hall. A ceiling that is too close would limit the controlling of the painting nozzle and the paint spray, and additionally there would be a risk that paint would be sprayed also onto the ceiling or its structures.

[0018] The horizontal suspension arrangement according to figure 1 comprises two diagonal support rails 36 and a horizontal support rail 37, which are arranged to be installed in connection with the suspension rail 1 by using the holes 6 in the suspension rail. The diagonal support rails 36 and the horizontal support rail 37 are arranged to form an equilateral triangle in connection with the suspension rail 1. Both ends 37A, 37B of the horizontal support rail 37 are arranged to be connected to the ends 36B of the diagonal support rails.

[0019] The horizontal suspension arrangement of figure 1 additionally comprises two side rails 38, which are arranged to be connected by their first ends 38A close to the ends K1, K2 of said triangle. These ends are formed from the connecting angles of the diagonal support rails 36 and the horizontal support rail 37. The horizontal rails 9 are arranged to be connected by both ends to the side rails 38.

[0020] The horizontal support rail 37, diagonal support rails 36 and side rails 38 are rails folded from a metal sheet, which rails have at least one fold in the longitudinal direction of the rail, whereby a good sturdiness and rigidity is obtained with a relatively light structure.

[0021] The first end 36A of the diagonal support rail 36 can have at least one hollow 39 for connecting/attaching the suspension rail 1, 12, and the second end 36B can have holes 40, 41 for connecting/attaching to the horizontal rail and side rail. Figures 4 - 6 show an example of the diagonal support rail. Both ends of the horizontal support rail 37 have a protrusion 42 and a hole 43 close to the ends. These are used for connecting the side rails 38 and the diagonal support rails. Figure 5 also shows the folding points 48 in the longitudinal direction of the rail, when the horizontal support rail has not yet been folded. Figures 7 - 9 show an example of the horizontal support rail.

[0022] The first end 38A of the side rail 38 has a hook arrangement 44 and the shaft has holes 45. The hook arrangement is used for connecting the side support to the corners K1, K2 of the above-mentioned equilateral triangle. The holes 45 are used to connect the horizontal rails 9 to the side rails. Figures 10 - 12 show an example of the side rail 38. Figure 12 also shows the folding points 49 in the longitudinal direction of the rail, when the side rail has not yet been folded.

[0023] As was noted above, the suspension protrusions can also be a fixed part of the horizontal rail. The suspension protrusions 19 can be arranged to be foldable into a suitable position. Figures 26 - 28 show one such embodiment. Figures 29 - 31 show another embodiment 46 of the horizontal rail with fixed protrusions 19. This embodiment has two folds 47 in the longitudinal direction of the rail. Figures 32 - 34 show still another embodiment 18 of the horizontal rail with fixed suspension protrusions 17.

[0024] Figures 14 - 17 show one embodiment of the horizontal rail 9. Figure 16 also shows the folding points 50 in the longitudinal direction of the rail, when the horizontal rail has not yet been folded. Figures 20 - 22, 35 - 37 and 38 - 40 show other possible embodiments 23, 14, 26 of the horizontal rail. Figures 36 and 40 also show the folding points 51, 52 in the longitudinal direction of the rails, when the horizontal support rails have not yet been folded. From different embodiments it can be discerned that holes 21, 22, 25, 24, 27 can be made in many different ways. Additionally, the ends of the rails, whether they are horizontal rails, side rails or other rails, can be shaped in a desired manner, whereby the are suited for each implementation in a desired manner, for example for connecting to other system parts.

[0025] With the solution according to the invention, the painting suspension arrangement takes up a relatively small amount of space in storage and transport. This is achieved, when the painting suspension arrangement is assembled at the use destination from several parts belonging to the system. Additionally, it does not always have to be completely renewed, when it has been used several times. Assembly of the painting suspension arrangement does not require welding or screws, and also no tools. The parts of the system are connected to each other by placing them against connecting shapes in the parts, such as holes, hollows, grooves and variously formed protrusions. Assembly is quick. The arrangement can be assembled even in less than one minute. The parts of the arrangement are easy to detach from each other and thus to exchange. This generates savings in costs and materials. The service life is thus longer altogether. Notable is also that with the metal sheet structure according to the invention, the bearing capacity/rigidity of the structure has been achieved with a relatively light structure in those parts of the painting suspension arrangement, where it is needed. This feature also generates savings in materials. Some of the parts of the system can be manufactured from metal sheets, which do not have a fold/folds, such as for example the suspension protrusions.

[0026] In light of the examples above it is clear that the embodiment according to the invention can be achieved with many different solutions. The shapes of different parts can be different, as also their size. The invention can thus be implemented with many different embodiments within the scope of the independent claim.
