Furthermore, the misting unit 36; 36.1, 36.2; 136, 136.1, 136.2 one into the hollow profile 32; 132 inserted fastening part 39; 139, which by means of a fastening means 43 fixed to the hollow section 32; 132 of the board unit 31 is connected. In the embodiments shown, the entire end cap 37; 137 made of plastic, so that both the cover 40; 140 and the fastening body 41; 141 consist of plastic. Preferably, the end cap 37; 137 of a thermoplastic material, such as polypropylene, which may optionally be filled or reinforced with fillers and / or reinforcing materials, in particular with reinforcing fibers such as glass fibers.

The design of the end caps 37, according to a first embodiment, in a not yet mounted on the board unit 31 state goes out of the FIGS. 6 to 11 out. The cover part 40 of the end caps 37 has a recess 44 in the form of a slot 45 which is closed completely here, which extends in the assembled state perpendicular to the longitudinal direction 33 or to the longitudinal axis 56 of the hollow profile 32. In the assembled state of the toe board 30; 30.1, 30.1 .1, 30. 1 .2; 30.2 is the fastening part 39 of the fitting unit 36; 36.1, 36.2 inserted through the slot 45 therethrough, so that then the fastening part 39 of the fitting unit 36; 36.1, 36.2 is fully enclosed in its entirety by the slot 45 of the end cap 37 delimiting wall parts of the cover 40. The inserted in the assembled state in the hollow section 32 of the board unit 31 mounting body 41 of the end cap 37 is here with two male bodies 73.1, 73.2 designed parallel to each other in the longitudinal direction 33 at a distance 74th are arranged extending to each other (see, for. Figures 9 and 10 ). Each male body 73.1, 73.2 is designed as a hollow body, which is in each case provided with a number of hollow chambers, which are here divided off from each other via vertical wall parts ( FIGS. 7 and 8th ). The male bodies 73.1, 73.2 here each have an approximately trapezoidal cross section ( FIG. 8 ). The outer contour and arrangement of the male body 73.1 and 73.2 relative to the cover member 40 is selected such that on the cover 40, an annular end edge 103 remains free, the cover for covering or covering the opposite in the mounted state end edges 38; 38.1, 38.2 of the hollow section 32 of the board unit 31 is used. This annular end edge 103 of the cover 40 at the same time forms a stop 77, on which the end edges 38; 38.1, 38.2 of the hollow profile 32 can rest in the mounted state (see, for example, FIG. FIG. 23 ).

The horizontal wall parts of each male body 73.1, 73.2 are each provided here with four recesses designed as through-holes 54.1, 54.2. These are arranged here in groups of two recesses 54.1, 54.1 and 54.2, 54.2 parallel to the longitudinal direction 33. In this case, each through-hole 54.1 is assigned a further through-hole 54.2, wherein the bore axes of these through-holes 54.1 and 54.2 each coincide. The through-holes 54.1 and 54.2 in this case each have the same inner diameter 100, which is for example about 11 mm ( Fig. 22 ).

Each male body 73.1, 73.2 has here a rectangularly limited receiving cavity 78.1, 78.2, which, starting from a here perpendicular to the longitudinal direction 33 extending and formed as a stop 63 wall part extends in the longitudinal direction 33 through the cover member 40 into the slot 45. These receiving cavities 78.1, 78.2 serve for the form-fitting reception of suitably designed attachment legs 71.1 and 71.2 of the attachment part 39 of the fitting unit 36; 36.1, 36.2, as used in the FIGS. 12, 14 and 15, 17 are shown.

In the respective receiving cavity 78.1, 78.2 projecting into a cross-section wedge-shaped projection of a resilient latching element 60, which is firmly connected here integrally with the end cap 37 at a front attachment point, but at its from this attachment point in the direction of the end face 75 of End cap 37 facing away end is received elastically deformable in a recess surrounding this end. Its function in cooperation with the fitting unit 36; 36.1, 36.2 will be explained in more detail in the following text.

The end face 75 of the end cap 37 is preferably beveled at an angle 76, which is preferably about 45 degrees. In this way, two on-board boards 30.1.1 and 30.1.2 provided with such end caps 37 can, for example, as in FIG FIG. 27 represented, virtually "mitred" with consistently small distance from each other.

The cover part 40 of the end cap 37 has on its side adjoining the acute angled end 103 of the end cap 37 side two in the longitudinal direction 33 erstrekkende part conical projections 59 on. The outer contour of each projection 59, at the level of the annular end edge 103 and the stop 77 of the cover 40, corresponds to the outer contour of a subsequent subsequent in the assembled state longitudinal rib 88.1, 88.2 of the hollow section 32 of the board unit 31. These longitudinal ribs 88.1, 88.2 are designed here as outwardly curved beads. On the side of the end cap 37 facing away from the conical projections 59, the latter has at least in the region of each of its plug-in bodies 73.1 and 73.2 and here also in the region of its cover part 40 a recess 69.1 which is circular or elliptical in cross section and extends in the longitudinal direction 33. 69.2. The inner contour of the recesses 69.2 in the male bodies 73.1, 73.2 corresponds to the inner contour of longitudinal ribs 88.3, 88.4 of the hollow profile 32 of the board unit 31, which are here designed as inwardly curved beads ( Fig. 18 ).

The in the Figures 36 to 40 shown end caps 137 are substantially identical to the end caps 37, but differ slightly in the design of their mounting body 141 and its cover members 140, as in particular FIG. 37 seen. While each fastening body 41 are divided into four hollow chambers by means of three longitudinal ribs ( FIGS. 8 and 24 ), each fastening body 141 is subdivided into two hollow chambers only by a single longitudinal rib ( FIG. 37 ). Further, the cover members and the attachment bodies 141 of the end caps 137 have recesses for receiving longitudinally extending beads 160, as shown in FIGS FIGS. 28 to 31 shown alternative embodiments of Beschokinheiten 136; 136.1, 136.2. Furthermore, the covers 140 of the end caps 137 have a T- or I-shaped stiffening profile in a central area, to which the two plug-in bodies 73.1 and 73.2 adjoin laterally, as in FIG Fig. 37 shown. Except for these differences are the End caps 137 the same shape as the end caps 37, so that in this respect can be made to the relevant remarks elsewhere in the description. Accordingly, the same elements of the end caps 137 are denoted by the same reference numerals as in the end caps 37.

Each mistrack unit 36; 36.1, 36.2; 136, 136.1, 136.2 comprises one in the assembled state of the end cap 37; 137 outstanding fixing part 101; 101.1, 101.2; 101.3, 101.4 and one in the assembled state through the slot 45 of the end cap 37; 137 through into the hollow section 32; 132 of the board unit 31 inserted fixing part 39; 139. The fastening part 39; 139 is here designed with two at a distance 72 and mutually parallel mounting legs 71.1, 71.2, through the slot 45 of the cover 40; 140 of the end cap 37; 137 through into the respective receiving cavity 78.1, 78.2 of the end cap 37; 137 are pluggable.

Each mounting leg 71.1, 71.2 of the fitting units 36; 36.1, 36.2; 136, 136.1, 136.2 has at least one attachment to the hollow profile 32; 132 of the board unit 31 serving recess 52.1, 52.2, which is here designed in each case as a through hole. Furthermore, it can be provided that each attachment leg 71.1, 71.2 with at least one to its fixation relative to the end cap 37; 137 serving recess 61 is designed, which is also designed in the embodiment as a through hole, preferably as a slot. The inner contour 67 of the recess 61 corresponds approximately to the outer contour 68 of the associated latching element 60 of the end cap 37; 137, so that the respective locking element 60 in the course of insertion the respective fitting unit 36; 36.1, 36.2; 136, 136.1, 136.2 into the end cap 37; 137 resiliently in the respective recess 61 of the fitting units 36; 36.1, 36.2; 136, 136.1, 136.2 can engage.

The formed as through holes recesses 52.1 and 52.2 of the mounting legs 71.1, 71.2 of the fitting units 36; 36.1, 36.2; ; 136, 136.1, 136.2 have a diameter 99, here the diameter 100 of the also designed as through holes recesses 54.1 and 54.2 of the male body 73.1, 73.2 of the mounting body 41; 141 of the end cap 37; 137 corresponds.

In the embodiments shown in the figures, the respective fitting unit 36; 36.1, 36.2; 136, 136.1, 136.2 in the over the end cap 37; 137 protruding portion (fixing member 101, 101.1, 101.2, 101.3, 101.4) is a substantially perpendicular to the longitudinal extension 33 of the mounting legs 71.1, 71.2 and in the assembled state substantially perpendicular to the longitudinal axis 56 of the hollow section 32; 132 of the board unit 31 and extending to one of the longitudinal longitudinal sides 33 extending narrow longitudinal end faces 87.2 of the board unit open towards slot 84, the slot bottom 85 is preferably arranged approximately at half the height of the board unit 31. That way you can two on-board boards 30.1.1 and 30.1.2 or 130.1.1 and 130.1.2, for example as in the Figures 27 and 40 shown, advantageously arranged and also fixed to each other or fixed by a first fitting unit 36; 136, for example, the fitting unit 36.1; 136.1 of the board 30.1.1; 130.1.1, into the slot 84 of a fitting unit 36; 136 a second on-board board 30, for example, a fitting unit 36.1; 136.2 of a second on-board board 30.1.2; 130.1.2, is plugged. As in the Figures 27 and 40 Thus, for example, the slot 84 of the fitting unit 36.1; 136.1 of the former board 30.1.1; 130.1.1 in the attached state to the fitting unit 36.1; 136.1 of the second toe board 30.1.2; 130.1.2 be plugged. In the attached state, the two narrow longitudinal end faces 87.1 or longitudinal edges of the two toe boards 30.1.1 or 103.1.1 and 30.1.2 or 103.1.2, and thus the upper edges thereof, are at the same height level.

The misting units 36; 36.1, 36.2; 136, 136.1, 136.2 are preferably made of flat steel 70. Their respective fixing part 1 01; 101.1, 101.2; 101.3, 101.4 can be designed with a through hole 102 into which a suspension hook not shown in the figures can be inserted. It is understood that in particular the design of the end cap 37; 137 outstanding fixing part of the fitting unit depending on the user and application needs may be designed differently than shown in the figures. For example, the fixing part can also be designed the same or similar, such as in the DE 100 61 506 A1 described and shown, the disclosure of which is incorporated herein in its entirety. The preferably consisting of flat steel 70 fitting units 36; 136 are in their on the front end 34.1, 34.2 of the hollow section 32; 132, in particular in their on the respective end cap 37; 137 protruding portion bent transversely to the longitudinal direction 33. The misting units 36; 136 are preferably made of a bent at least twice bent steel sheet 70 (see, in particular Figures 13 and 16 as well as 29 and 31).

The main difference between the particular in the FIGS. 12 to 14 or 28 and 29 shown fitting unit 36.1 and 136.1 and in particular in the FIGS. 15 to 17 shown fitting unit 36.2 and the particular in the FIGS. 30 and 31 Fitting unit 136.2 is shown in that the fixing part 101.2 or 101.4 of the fitting unit 36.2 or 136.2 has a projection unit 57 or 157, which in the assembled state of the fitting unit 36.2 or 136.2 on the board unit 31 with a distance or projection 58 on a the narrow longitudinal end faces 87.1 protrudes ( Figures 2 and 4 ). With regard to such a construction and its advantages may at this point for simplicity on the DE 202 02 659 U1 be referenced, the disclosure of which is fully incorporated here.

The particular in the FIGS. 28 to 31 shown embodiments of a fitting unit 136; 136.1, 136.2 differ from those in particular in the FIGS. 12 to 17 shown embodiments of a fitting unit 36; 36.1, 36.2 essentially by the design of their fixing 101.3, 101.4. In contrast to the fixing parts 101.1, 101.2, the fixing parts are 101.3, 101.4 in comparatively narrow radii, preferably from 1 to 4 mm, in particular of about 2.5 mm, forming about legs 163.1 and 164.1 or 163.2 and 164.2 formed at right angles to one another are bent twice, wherein the respective legs 163.1 and 163.2 are also approximately perpendicular to the respective fastening part 139 or to their respective fastening legs 71; 71.1, 71.2 is arranged or bent. The respective transverse leg 163.1, 163.2 extends starting from the respective fastening part 139 or from its respective fastening limbs 71; 71.1, 71.2 away in a first direction. While the fixing parts 101.1 and 101.2 are bent at an angle of about 45 degrees, the fixing parts 101.3 and 101.4 are bent at an angle of about 90 degrees. By the latter measure, increased security against a longitudinal displacement of a toe board 130 or a plurality of toe boards 130-130 can be achieved, both in an arrangement in line or in the longitudinal direction one behind the other and in a corner arrangement of two toe boards 130-130, such as in Fig. 40 shown.

Furthermore, the fitting units 136; 136.1, 136.2 each at the level of their two attachment legs 71.1 and 71.2 each with two stiffening beads 160; 160.1, 160.2 provided. The beads 160; 160.1, 160.2 are each arranged parallel to one another and approximately perpendicular to the slot 84. In each case two of the beads 160 are associated with one of the fastening legs 71.1, 71.2. Here are the two beads 160.1 the mounting leg 71.1 and the two beads 160.2 assigned to the mounting leg 71.2. The beads 160; 160.1, 160.2 are formed or attached in such a way that they move away from the attachment part 139 or from its attachment legs 71; 71.1, 71.2 in a second direction opposite to the first direction of extension of the legs 163.1, 163.2 extend away. The respective two beads 160.1 assigned to the respective fastening leg 71.1 extend starting from the respective fixing parts 101.3, 101.4 continuously into the respective fastening leg 71.1. In contrast to this, the respective two beads 160.2, which are assigned to the respective fastening leg 71.2, are interrupted by the respective slot 84, wherein a first part of the respective bead 160.2 extends in the fixing part 101.3, 101.4, while a second part of the respective Beading 160.2 extends from the respective fixing part 101.3, 101.4 out into the respective fastening leg 71.2. In the embodiments shown in the figures protrude in the fully assembled state all beads 160; 160.1, 160.2 both into the end cap 137 and beyond the cover 140 out (see Figures 37 . 39 and 40 ). The optionally providable beads 160; 160.1, 160.2 serve for better stiffening of the respective fitting unit 136.

Again in contrast to the particular in the FIGS. 12 to 17 shown embodiments of the fitting units 36; 36.1, 36.2 is located at the fitting units 136; 136.1, 136.2 the respective hole 102 in that part of the fitting unit 136; 136.1, 136.2, between the legs 163.1, 163.2 and the mounting legs 71; 71.1, 71.2 is arranged. In the embodiments shown, the respective hole 102 is in the region of the front end of the respective outermost bead 160.1 of the respective two, the fastening leg 71.1 associated beads 160.1.

Especially in the FIGS. 1 to 4 and 18 to 27 is a first embodiment of a galvanized sheet steel here 29 existing hollow profile 32 is shown, on which the fastening body 41 of the end cap 37 and the fastening part 39 of the fitting unit 36; 36.1, 36.2 are fastened by means of deformed wall parts 47.1, 47.2 of the hollow profile 32.

The design of the hollow profile 32 in a state prior to assembly and attachment of the end cap 37 and the fitting unit 36 on the hollow profile 32 goes out of the FIGS. 18 to 22 out. The hollow profile 32 is made of a blank of sheet steel 29 by bending and / or folding the same, in particular in or on a Rollenprofilierstraße. In this case, the two longitudinal ends 83.1 and 83.2 of the blank made of sheet steel 29 are advantageously joined together by separate mechanical fastening means, such as rivets or screws and also free of a separate joining material welding method here on impact 93, using either a press-joining process, such as clinching, clinching and / or roll cut stamping or using a laser welding process. In this case, the two longitudinal ends 83.1 and 83.2 of the steel sheet blank are preferably connected to one another over the entire or essentially the entire length of the hollow profile 32 and / or to an opposite wall part 47.1 of the hollow profile 32. The wall thickness of the hollow profile 32 is preferably less than 2 mm, in particular less than 1 mm, for example 0.8 mm or only 0.6 mm.

The hollow profile 32 of the board unit 31 has in the region of each of its front ends 34.1, 34.2 a number of here eight through holes 49, which corresponds to the number of recesses or through holes 54.1, 54.2 in the Fixing body 41 of the end cap 37 corresponds. These through-holes 49 in the hollow profile 32 have in a state in which the end cap 37 and the fitting unit 36; 36.1, 36.2 not yet plugged into the hollow profile 32 and are positively connected to this, a diameter 50 which is much smaller than the diameter 99 of the openings designed as recesses 52.1, 52.2 in the mounting legs 71.1, 71.2 of the fixing part 59 of Fitting unit 36; 36.1, 36.2 and accordingly also very much smaller than the diameter 100 of the recesses 54.1, 54.2 of the plug-in bodies 73.1, 73.2 of the end cap 37, likewise designed as passage openings. The diameter 50 of the through-holes 49 in the exemplary embodiment is approximately 4.5 to 5 mm.

The end edges 38.1 and 38.2 of the hollow profile 32 span a plane perpendicular to the longitudinal extent 33 or perpendicular to the longitudinal axis 56 of the hollow profile 32 arranged plane. The hollow profile 32 is designed in the embodiment shown with two cross-sectionally closed longitudinal beams 80.1 and 80.2, which are both formed as edge spar 81.1 and 81.2 and which extend over the entire length of the board unit 31. The longitudinal bars 80.1 and 80.2 have, in a section perpendicular to their longitudinal axis or perpendicular to the longitudinal axis 56 of the board unit 31, a box-shaped, here trapezoidal cross-section 82.1, 82.2. In this case, the wall portions of the longitudinal members 80.1 and 80.2 arranged opposite one another at a distance and starting from a double wall region 91 having a width 94 are each arranged at an angle 92 to a vertical to a wall portion 47.1 of a first wide longitudinal side 86.1 of the board unit 31 ( Fig. 18 ).

Each of the longitudinal beams 80.1, 80.2 designed as edge beams 81.1, 81.2 has sides pointing away from one another, which form a wall portion of the wide longitudinal sides 86.1 and 86.2 of the board unit 31 facing away from one another, in each case substantially or over their entire length extending, designed as beads Longitudinal ribs 88.1, 88.2; 88.3, 88.4 on. The longitudinal ribs 88.1 and 88.2 arranged on the first wide longitudinal side 86.1 each extend above the outer boundary surfaces 89.1 of the first wide longitudinal side 86.1 of the board unit 31 and the second longitudinal ribs 88.3, 88.4 arranged on the second wide longitudinal side 86.2 extend below the outer boundary surface 89.2 of FIG from the first wide longitudinal side 86.1 facing away second wide longitudinal side 86.2 of the board unit 31. These second longitudinal ribs 88.3 and 88.4 thus each extend into the cavities of the respective longitudinal spar 80.1, 80.2 inside. The longitudinal ribs 88.1 and 88.3 of the longitudinal member 80.1 each have to the first narrow longitudinal end face 87.1 of the board unit 31 at a distance 90.1 or 90.2, which is the same size here. Furthermore, the longitudinal ribs 88.2 and 88.4 of the longitudinal beam 80.2 from the other narrow longitudinal end face 87.2 of the board unit 31 at a distance 90.1 or 90.2, which is also the same size here. Furthermore, here both the two distances 90.1, 90.1 and the two distances 90.2, 90.2 are each the same size. These distances 90.1, 90.2 amount to between 15 and 35 mm, preferably between 20 and 30 mm and in the exemplary embodiment about 24 mm. These distances 90.1, 90.2 of the longitudinal ribs 88.1, 88.2; 88.3, 88.4 to the respectively associated narrow longitudinal end face 87.1, 87.2 of the board unit 31 is selected such that it grasps the board unit 31 by hand from one of its narrow longitudinal end faces 87.1, 87.2 Thus, at least one of the longitudinal ribs 88.1, 88.2 on a first wide longitudinal side 86.1 of the wide longitudinal sides 86.1, 86.2 of the board unit 31 with at least one first finger of the hand behind is gripped or that at least one first finger of the hand in at least one of the longitudinal ribs 88.3 , 88.4 on a first wide longitudinal side 86.2 of the wide longitudinal sides 86.1, 86.2 of the board unit 31 can engage while at the same time another finger, preferably the thumb of the same hand on the side facing away from the first wide longitudinal side 86.1 or 86.2 second broader longitudinal side 86.2 or 86.1 of the board unit 31 can attack.

The longitudinal ribs 88.1, 88.2; 88.3, 88.4 are designed and arranged such that they allow a stacking of a plurality of on-board boards 30, 30 to form a positive connection of the stacked toe boards 30, 30, which forms a displacement of the toe boards 30, 30 perpendicular to their respective longitudinal extension 33.

Hereinafter, the mounting and mounting of the fitting units 36; 36.1, 36.2 and the end caps 37 with or on the hollow profile 32 of the board unit 31 to form a toeboard 30 according to the invention described:

In a first step, the misting units 36; 36.1, 36.2 each firmly connected to an end cap 37, the fixing body 41 of the end cap 37 and the fixing part 39 of the fitting unit 36; 36.1, 36.2 each form a plug-in unit 97. It is therefore first the respective fitting unit 36; 36.1, 36.2 with their attachment legs 71.1 and 71.2 in the forward insertion direction 62 (FIG. Figures 12 and 15 ) inserted through the slot 45 of the cover 40 of the end cap 37 into the respectively associated receiving cavity 78.1 and 78.2 of the end cap 37. In this case, the free insertion ends of the attachment legs 71.1 and 71.2 reach the in the respective receiving cavity 78.1. 78.2 extending part of the respective latching element 60 and in the course of a continued insertion of the fitting unit 36; 36.1, 36.2 in the end cap 37, the resilient locking elements 60 are pressed against the spring forces inwardly. In the course of further mounting or insertion of the fastening part 39 of the fitting unit 36 in the insertion direction 62 into the end cap 37, the respective latching element 60 automatically engages in the respective recess 61 of the fastening legs 71.1 and 71.2 of the fastening part 39 of the fitting unit 36. The insertion or insertion of the fastening part 39 of the fitting unit 36 onto or into the end cap 37 is limited by a stop 63 (FIG. FIGS. 10 and 11 ), on which the fastening part 39 of the fitting unit 36 when attaching or plugging on or in the end cap 37 can strike, so that the fitting unit 36 in the assembled state in a predetermined position preferably by the position of the stopper 36 relative to the end cap 37 is located. The stop 63 and the locking element 60 of the end cap 37 are arranged at a distance 64 which is equal to or slightly larger than the distance 65 between the locking element 60 associated recess 61 of the fastening part 39 of the fitting unit 36 and a stop 63 associated with the end edge 66 of the fastening part 39 of the fitting unit 36 (see Figures 11 . 12 and 15 ). It can thereby be achieved that the latching element 60 engages in the assembled state to form a positive connection in the through hole 61 of the fastening part 39 of the fitting unit 36 such that the fastening part 39 of the mounted on the end cap 37 fitting unit 36 at least against withdrawal in one direction the insertion direction 62 is secured. In this way, therefore, one obtains first a simple and safe to handle unit consisting of the end cap 37 and plugged into this fitting unit 36, which is captive and preferably permanently connected to the end cap 37. This unit comprises a plug-in unit 97 which is formed by the fixing part 39 of the fitting unit 36 and the fixing body 41 of the end cap 37.

In a second step, the plug-in unit 97 can subsequently be inserted into the hollow profile 32 of the board unit 31, as described, for example, in FIG FIG. 22 is illustrated.

In a third, subsequent step, the fastening part 39 of the fitting unit 36 and also the fastening body 41 of the end cap 37 are firmly connected to the hollow body 32, free of separate mechanical fastening means, such as rivets or screws and forming a positive connection 46.1, 46.2. In the embodiment shown, not only the fitting unit 46 and the end cap 37 to form a positive connection 46.1, 46.2 with the hollow profile connected, but it are also the fitting unit 36 and the end cap 37 connected to form a positive connection with each other. In this regard, in particular the Figures 23 and 24 to point.

According to the invention, the positive connection 46.1, 46.2 is achieved by a local deformation of a wall portion 47.1, 47.2 of the hollow profile 32 effecting pressing operation. The deformation can be achieved by drawing in or pressing in a hole edge region 48 of a hole 49 provided in a wall part 47.1, 47.2 of the hollow profile 32, here by means of press dies 51.1, 51.2, 51.3, 51.4 (FIG. FIG. 22 ), in one of the recesses 52.1, 52.2; 54.1, 54.2 of the fastening part 39 of the fitting unit 36 and the fastening body 41 of the end cap 37 are achieved. In this case, the positive connection 46.1 of the fitting unit 36 with the hollow profile 32 and the positive connection 46.2 of the end cap 37 with the hollow profile 32 under the simultaneous action of a plurality of press rams 51.1, 51.2, 51.3, 51.4 prepared on mutually pathing longitudinal sides 86.1, 86.2 of the hollow profile 32nd attack at this in opposite directions 95, 96 ( Fig. 22 ).
