Description

in DK 176166 B1

The invention relates to a sign, such as a road sign or road sign, with one or two signboards and with a frame, which sign is of the kind specified in the preamble of claim 1. The invention further relates to a profile of 5 uniform cross sections, for forming a frame for a sign of said kind, which profile is of the kind specified in the preamble of claim 6.

European Patent Application No. 499,517 discloses a sign and profile of said species. The known profile 10 has recesses on the sides to receive the edge sections of the signboards, which are attached to the frame by gluing. The recesses are formed between one of the profile sides facing the signboard and the outside of the profile.

The profile has T-shaped grooves, both on its outside 15 and on its inside, where the groove on the outside is used for engaging hook means when mounting the sign. To this end, the T-shaped groove has a substantially trapezoidal or rectangular cross-section. The hook members engage with one of the rib-shaped projections projecting inwardly from the side walls of the T-shaped groove. Securing the sign against turning in its fasteners is achieved by using two hook means, combined with a flat face on the sign post, which face faces the sign.

The sign and profile thus described has several disadvantages. First, it is a disadvantage that the signboards have to be mounted by gluing, such as using double-sided adhesive strip. This process cannot be easily automated and is therefore time consuming. Larger road signs or road signs are subject to high wind forces, and sizing does not appear to be satisfactory in mechanical strength over extended periods of time under such conditions. Second, the lateral flange will tend to bend toward the corner center as the profile is bent to form the lifting means, thereby affecting the accuracy of the radius of the recess to receive the sign plate and the regularity thereof. the appearance of finished signs will deteriorate.

2 DK 176166 B1

Danish Patent No. 154,920 discloses a sign with a frame profile for a circular frame for the sign plate, where the frame profile has a flat, smooth abutment against the sign plate, which is held to the profile with screws, rivets, glue 5 or otherwise. At the rear of the frame, opposite to its abutment against the sign plate, the profile has a T-groove which serves to receive specially designed double nuts with two internal threads, with which the frame parts can be clamped together or fixed to other parts such as suspension or support elements. extending over inner portions of the sign plate and supporting it.

An entire frame for a square signboard is composed here of straight frame profiles and frame corners. The frame corners are hereby made of the same cross-section as the frame profile by bending this with a certain radius. These parts are clamped together by means of said double nuts as well as lugs and machine screws.

The formed sign frame can be laterally displaced by hanging on a vertically extending stand or mast, the mast attachments being able to engage long double nuts slidable in the T-groove until the screws are tightened.

It is a disadvantage of the sign and profile described here with associated parts that an extremely large number of parts is required to form a complete sign. In particular, 25 many screws and bolts are included in addition to many of the double nuts mentioned and associated two-hole screw plates.

Manufacturing of the sign according to Danish Patent No. 154,920 involves cutting a very large number of profile parts, as well as making separate corners. This in itself is labor intensive and costly, but also involves a great deal of work to create and assemble the parts. The sign is apparently not self-supporting until all or nearly all parts are fitted.

Furthermore, it is a disadvantage of the described profile 35 for forming the frame that the plate must be fixed separately to the frame with rivets, glue or the like.

Finally, it is a disadvantage of the sign in Danish Patent No. 154,920 and the associated profile system that these are not applicable to two-plate signboards. Such signs are in ever-increasing use, for example, for signs that include displays or moving elements such as text that is changed, or signs where the front panel is illuminated from the inside.

5 The sign must be handled by suspension and dismantling with generally known means, since it is not specially designed for ease of handling.

US Patent No. 4,805,324 discloses a two-plate plate and a frame comprising an elongated profile, which has two grooves on its inside, each receiving the edge of a plate, and which has a T-plate on its outside. However, only two of the frame sides are designed as indicated, the other two sides of the frame being made up of terminating elements, which include a is not provided with a T-shaped groove on the outside. The framework is thus made up of four parties, which makes it unnecessarily complicated. The frame profile has a cross section with very low moment of inertia. It is therefore not very rigid and will not be able to bend to form a frame hay. Finally, the T-shaped groove is very small and therefore only suitable for clamping small signs.

From British Patent Application No. 2,250,850 there is known a road sign with an access opening which is closed with a hinged lid. The sign is suspended in that the lid is clamped to a sign post, and the sign can thus be pivoted away from the stand and lid, around its hinges. Of course, this construction requires the hinges to be very sturdy and therefore expensive. Since the access opening is located in one sign plate (back plate), the opening does not allow access to carry long objects such as fluorescent lamps into or out of the sign.

30 From US Patent No. 3,531,882, an internally illuminated sign is known in which a suspension member in the form of a boom extends through an opening at the edge of the sign and further through the interior of the sign between the two sign plates. However, this sign is not constructed with a supporting frame or otherwise with a good power transfer from the signboards to the boom. The described structure is therefore quite unsuitable for large signs such as road signs which are influenced by very large wind forces.

4 DK 176166 B1

The invention provides a plate of the kind mentioned in the first place where the above-mentioned drawbacks are avoided, the plate consists of considerably fewer parts than the known ones and where a finished plate with one or two plate plates can be suspended with slidability by means of brackets of considerably simpler design and with fewer parts than the known ones. Preparation of the sign according to the invention can be done with very few work operations. In addition, the sign can be lifted and handled by 10 simple and labor-saving means by hanging and removing. Finally, it is achieved that the sign gets a simple and appealing appearance and is therefore suitable for applications where emphasis is placed on the quality of the sign as so-called street furniture, and that the sign has fewer nooks and crannies, which can collect dirt and serve as a residence or space for birds.

This is achieved according to the invention by means of the features defined in the characterizing part of claim 1. By including the recesses, it is achieved that the signboards can be mounted in a very fast and simple manner, while the frame 20 is assembled, by simply letting the signboards edges intervene in the notes. By the walls having a wall thickness greater than the wall thicknesses in the remaining sections of the elongated profile, on the one hand, it is achieved that the cross-section of the profile achieves a large moment of inertia, whereby the profile becomes rigid, which greatly contributes to making the frame is stable and signposted self-supporting without the use of separate support elements, and on the other hand that those of the profile walls which are clearly visible on the finished sign are not appreciably deformed when the profile is bent with a radius of 30 to form a frame corner.

According to claim 2, one side of the frame, two corner portions adjacent to this side and two side portions adjacent to these corner portions can be manufactured as a unit from a profile of uniform cross section by bending the profile at two places with a certain radius to forming the corner portions, obtaining a complete frame for a sign with one or two signboards by means of a few main parts and only a very small number of fittings. The frame is manufactured in a few steps. The formed frame has a high stiffness and is inherently robust. Due to the low number of parts, the sign is manufactured quickly, is easy to assemble and is self-supporting.

In accordance with claim 3, it is achieved that an access opening can be manufactured inexpensively and without the need for additional stiffening around the opening, and that the opening and an associated lid are not immediately visible from the outside.

In accordance with claim 4, it is achieved that means for controlling and holding the lid can be made extremely cheaply.

The method of claim 5 prevents the sign from twisting around suspension point terrains in a simple and inexpensive way, so that the sign can be safely twisted with 15 fewer brackets. At the same time it is achieved that the sign before the final clamping is slidable, but still safely carried during shearing.

In addition, the invention provides a profile of the kind mentioned initially, with which a frame for a sign according to the invention can be produced in a particularly advantageous way.

This is achieved according to the invention by means of the features defined in the characterizing part of claim 6.

By including the recess members, it is achieved that the signboards can be mounted in a very quick and simple manner as the frame is assembled, by simply letting the edges of the signboards engaging the notes. By the walls having a wall thickness greater than the wall thicknesses of the remaining sections 30 of the elongated profile, on the one hand, it is achieved that the profile's cross section achieves a large moment of inertia, thereby making the profile rigid, which greatly contributes to making the frame stable and signposted self-supporting without the use of separate support members, and, on the other hand, those of the profile walls which are readily visible on the finished sign are not appreciably deformed when the profile is bent with a radius to form a frame corner.

6 DK 176166 B1

In accordance with claim 7, it is achieved that the profile can be bent with a suitable radius in a very simple tool, without means to secure the different sections of the profile against deflection perpendicular to the longitudinal direction of the profile.

As stated in claim 8, it is achieved that the walls will have a greatly reduced tendency to collapse laterally as the profile is bent to form the corner portions.

It is further achieved that those of the sidewalls facing outward form a visible frame around the sign plate, which contributes to an appealing appearance of the finished sign.

In accordance with claim 9, it is achieved that the T-groove is formed with minimal consumption of material and that the T-groove has such dimensions that it can accommodate and grip sufficiently large lids and sufficiently solid means for torsion protection and suspension.

In accordance with claim 10, it is achieved that the profile can easily be used for conveying cables and wires for interior lighting, or moving elements or displays.

In accordance with claim 11, it is achieved that the ribs can grip tightly on elements such as lids or means such as torsion protection fittings which are slightly narrower than the cross-section of the opening of the T-track and can therefore be inserted through it without further ado.

In accordance with claim 12, an improved holding of the signboards is achieved.

In the characterizing part of claim 13, it is firstly achieved that the groove can be open when the sign plate is inserted, whereby this can be done in a simple manner and that the groove can subsequently be closed by bending or rolling the clamping rib to a closed position, whereby the sign plate is particularly effectively retained, and secondly, that an extrusion tool for producing the profile by extrusion can be produced without very thin projections corresponding to the dimensions of the groove in its closed state.

In the claim 14, an extremely stable, inexpensive and torsion-proof suspension of a sign is laterally obtained from a mast.

7 DK 176166 B1

In accordance with claim 15, an extremely stable and secure assembly of the half-frame of the frame is obtained with loops of quite simple and inexpensive design.

In the claim 16, an extremely stable and secure transfer of torsional forces is obtained from the frame of the sign to the boom's torsional protection.

The invention will now be explained in more detail by way of example and with reference to the drawing, in which: FIG. 1 shows a cross section of a profile according to the invention; FIG. 2 shows two signs according to the invention, each suspended laterally on the same mast by means of a through boom; FIG. 3 is a vertical section along the center plane of one of the signs in FIG. 2 on a larger scale; FIG. 4 is a vertical section taken along line IV-IV of FIG. 3 on a further scale; FIG. 5 is a sectional view of an edge portion of a plate according to the invention showing the retention of a lid over an access hole in the frame; FIG. 6 shows a vertical cross section of the mast plane in a sign according to the invention, suspended in the middle of a mast; FIG. 7 is a section along line VII-VII of FIG. 6, 25 FIG. 8 is a partial sectional view taken along line VIII-VIII of FIG. 6, and FIG. 9 and 10 show the lifting of a sign according to the invention by means of suitable lifting devices.

In FIG. 1 is a cross-sectional view of an elongated profile 1 according to the invention for forming a frame for a sign with one or two sign boards. Such a sign 2 can be seen in FIG. 2, where two signs 2 are suspended over each other laterally from a mast 3. Each sign 2 has a frame 4 which surrounds a sign plate 5. The frame 4 is formed with round corners 6, all 35 having the same radius of curvature. In FIG. 5 is a cross-sectional view of an edge portion of such a sign 2 with a frame constituted by the profile 1 and two sign plates 5, one of which faces each side, in FIG. 5 on the right and on the left.

8 DK 176166 B1

Two sign boards 5 may be required if the sign is to display information on both sides, or if the sign is to contain a cavity for displays or the like, or to be illuminated from the inside. The sign according to the invention can optionally be formed with one or two sign plates, simply by adding the desired number of plates when assembling the sign, see below.

The profile 1 is preferably made of a suitable aluminum alloy by extrusion. The signboards 5 may be of aluminum if they merely carry information which must be readable when the sign is illuminated by day or artificial light or by reflection of e.g. lights from the headlights of motor vehicles. The plates 5 may be of plastic such as acrylic or polycarbonate if the sign is designed with internal lighting.

On page 7 of profile 1, as in -fig. 1 and 5 face downward and corresponding to the inside of the frame, the profile 1 has two grooves 8 and 9 for each to receive the edge of one separated plate 5. When the frame 4 as shown in FIG. 2 surrounding the sign plates 20, these are securely retained in the grooves 8, 9.

The profile has on the side which corresponds to the outside of the frame and which faces upwards in fig. 1, a T-shaped groove or a T-groove 10. The T-shaped groove 10 is formed between the bottom 11 of the profile, two walls 12 and 13, and two rib-shaped projections 16 25 and 17. The two walls 12 and 13 are projected from portions 14, 15 located on either side of the bottom 11 and each containing one of the two grooves 8, 9. Each wall 12, 13 extends in a plane parallel to and substantially coincident with the corresponding sign plate 5 plan. The two rib-shaped projections 16 and 17 project from the edge of the walls 12, 13 and extend parallel to the bottom 11 and towards the corresponding edge of the second wall 12, 13.

The aperture 20 between the two rib-shaped projections 16, 17 free edges 18, 19, which form the width of the 35 T-shaped groove 10 outwardly, has a cross-dimension greater than 40%, preferably greater than 50%, and especially preferably approx. 60% of the total width of the profile. By designing the T-groove 10 with such a relatively wide opening, access openings of a suitable size with associated lid can be formed at the bottom of the T-groove. At the same time, material for the production of the profile 1 is saved.

Such an access opening 21 with associated cover 22 is shown schematically in FIG. 5. It can be seen from the figure that the opening of the T-groove between the free edges 18, 19 is sufficiently wide for the lid 22 to be easily removed through this opening, while at the same time the lid being sufficiently wide to cover the relatively wide access opening 21. The lid is retained in the shown shape of the illustrated embodiment by means of a bolt 24 screwed through a yoke 23 which clings to the inner surfaces of the rib-shaped projections 16, 17 in the T-groove 10. When the lid 22 is to be removed the bolt 24, after which the yoke 23 can be turned about the axis of the bolt and removed from the T-groove. Then, lid 22 can be removed.

X the embodiment of the profile 10 shown in the figures, from the bottom 11 of the profile 10, ribs 26, 27 enter into the T-shaped groove, in a direction perpendicular to the direction of the bottom. The ribs 26, 27 are shown here disposed near the right-angled projections 30, 31 on the bottom 11 of the free edges 18, 19. of the rib-shaped protrusions 16, 17, thereby forming as shown in FIG. 1 shows two pockets 28, 29 in the corners of the T-groove 10 connecting the bottom 11 and the walls 12, 13.

These pockets can serve for guiding cables or 25 wires to the interior lighting of the sign or to electrical or electronic displays or moving elements for displaying varying text, etc. on the sign.

In addition, a groove 25 is formed between the ribs 26, 27 with a width which is preferably slightly smaller than the opening of the T-groove 30 between the free edges 18, 19. This is achieved when the ribs 26, 27 are as shown slightly within the projections. 30, 31. This groove 25 may serve to control the above-mentioned lids 22, as well as to receive stabilizing suspension brackets, which will be discussed below.

The side walls of the grooves 8, 9 for accommodating the edges of the plates 5 are preferably provided with protruding beads 32 which engage the plate 5 when placed in the groove. In FIG. 1, it is indicated by dotted step 10 B1 that a sign plate 5 is arranged in the groove 8 and that the beads on the sidewalls of this groove engage the sign plate. Preferably, the beads are sharply edged so that they can deform the surface of the sign plate 5.

5 In FIG. 1, the groove 9 is shown in an open state, having a substantially V-shaped cross-section. The groove 9 is formed between a rib-shaped portion 33 extending between the bottom 11 of the T-shaped groove 10 and the wall 13, and a clamping rib 34 extending from the same wall 13 at an oblique angle. Clamp 10 rib 34 is formed by means of a weakening in the form of a round-bottomed groove 35 that can be bent or rolled to a position similar to the condition of the groove 8 in FIG. 1, wherein said inclined angle is approximately zero.

In constructing the sign according to the invention, the sign plate (s) 5 are placed in the grooves 8, 9 while in the open state corresponding to pos. 9 in FIG. 1, after which the clamping ribs 34 are rolled or bent with a suitable tool until the grooves 8, 9 are in the closed state corresponding to pos. 8 in FIG. 1. In this position 20, the sign plates 5 are clamped in the grooves 8, 9.

In practice, the profile 1 will be extruded with the clamping ribs 34 in the open position (pos. 9), thereby obtaining the additional advantage that the projections in the extrusion matrix forming the grooves 8, 9 can be formed substantially more solidly. , than if the grooves were to be extruded in the closed state (heading 8).

The frame 4 for a sign 2 is made of the profile 1 by bending the profile 90 ° with a certain radius where the sign must have corners 6 (Fig. 2). According to the invention 30, the frame 4 is preferably made into two half-pieces, each comprising one of the sides of the frame 36, two corners 6 adjacent to this side and two side portions 37, 38 adjacent to these corners, see fig. 2. These two halves are thus each formed in one of the profile 1. The joint joints between such 35 two halves are denoted by 39.

In connection with the lower plate 2 in FIG. 2 it is indicated by a dashed line how the half-parts of the frame 4 are made: Two elements 40 in a buckle bearing are fixed at the desired distance and the profile 1 is not clamped in abutment against these elements. Thereafter, the free ends 41 of the profile are bent as indicated by arrow 42 to the desired position 43. The bucket teacher can in itself in a known manner be constructed as a machine in which the bending takes place by mechanical means. Special measures can be taken to prevent the profile from deforming across its main extent, for example by inserting a spacer between the free edges 18, 19 to prevent the T-track from collapsing and becoming narrower the corner lots 6.

The main dimensions of the profile 1 are chosen so that the profile can be bent with a suitable radius. Thus, according to the invention, the height of the profile in the direction of the walls 12, 13 is less than 50% of, preferably less than 40% of, and especially preferably about equal to 30% of, the width of the profile in the direction of the bottom 11.

In a preferred embodiment, the walls 12, 13 are formed with a thickness greater than the thickness of the other sections 11, 16, 17 of the profile, preferably greater than 1.5 times the average of the thicknesses of the bottom 11 and the rib-shaped projections 16 , 17, and particularly preferably about twice the average mentioned. This preferred embodiment corresponds to the appearance of the profile 25 in FIG. First

However, tests have shown that the profile 1 in this preferred embodiment can be bent with a radius of approx. 70% of the profile width without the use of measures to prevent the profile from deforming or even 30 collapsing.

EXAMPLE

A profile with dimensions as shown in FIG. 1, width x height 100χ30 mm, thickness of 4 mm in bottom 11 and in the 35 rib-shaped projections 16, 17, and thickness of 8 mm in walls 11, 12, were extruded by an aluminum alloy.

The profile was bent 90 ° in a ladder over a cylindrical shape with a radius of 70 mm and two circular guide tabs which engaged the grooves 8, 9. The profile was held against longitudinal displacement at one end, but no action was taken. measures to deform the cross section of the profile.

It turned out that there was no deformation of the exteriors of the walls 12, 13 or of the clamping ribs 34 (overturning, sinking or similar). The visible part of the corner thus had the desired regular shape, which was quite similar to the shape of the right sides. This is believed to be essentially due to the increased thickness of 8 mm in the walls 11, 12.

The bottom 11 was deformed, curving a portion outwards in the corner, and the two rib-shaped projections 16, 17 were pulled slightly inward. However, none of these deformations had any practical significance, and the 15 did not give any undue visual impression.

Preferably, the two halves of the frame 4 are joined together by 20 shaped elements which overlap a joint 39 and engage the T-shaped groove 10 in each of the halves. The engagement preferably takes place between the ribs 26, 27 in the same way as the lid 22 engages, see fig. 5. This provides a stable and rigid connection between the half-parties. In general, joints between two parts made of the profile 1 can be conveniently made in this way, even where the profile is used in a different way than for the construction of a sign frame 4 consisting of two half-parts.

In FIG. 3 is one of the signs 2 in FIG. 2 shown through the cut along the center plane of the sign. Two openings are formed in the frame, where the frame's half-pieces are collapsed (heading 39). These openings, not shown in detail, serve to penetrate a boom 44, here comprising a 35 square cross-sectional iron pipe, through the interior of the sign between the sign plates 5, the rear of which is visible in FIG. 3. The boom 44 carries the sign 2, being secured to the mast 3 by means of suitable brackets, etc. 45. In these fittings 13 DK 176166 B1 and in the mast there is hole 46, through which cables or wires can be concealed into the interior of the sign through the boom 44. The 4 half parts of the frame are assembled by means of lugs which engage the groove 25 between ribs 26 and 27, in the same manner as shown in FIG. 5th

Here, these lugs are rigidly connected to the boom 44, thus serving the dual purpose of holding the frame halves together and securing the sign rigidly and securely to the boom. The latches are formed by a through liner 47 welded 10 to the end of the boom 44, and two welding portions 48, 49 which are welded to the boom where it passes through the sign frame closest to the mast 3. The latches are attached to the frame halves in the groove 25 between the ribs 26, 27 (see Fig. 1) by means of bolts 51 passing through the lugs and screwed into counter-lugs 50 which abut the underside 7 of the frame profile (Fig. 1). The pieces of the frame halves against which the lugs 47-49 are provided are provided with slots corresponding to the bolts 51, so that the frame halves can be slid in between the lugs 47-49 and the counter lugs 50 after the bolts 51 20 are screwed in half.

Hereby, the sign can be assembled in this order: The boom 44 with the welded lugs 47-49 is placed on a level surface and supported appropriately. The counter-blades 50 are placed and the bolts 51 are screwed in half so that there is air between 25 blades and counter-blades. The frame halves are now slid into place in directions similar to the vertical in FIG. 3, at the same time that the sign plate or plates 5 are placed in the grooves 8, 9. When the frame halves are shot in place, corresponding to the positions they occupy in FIG. 3, the bolts 51 are tightened, and the billet 2 and the boom 44 now form a fixed unit. The sign plates 5 lie loosely in the grooves 8, 9, but cannot be removed from them. Finally, the grooves 8, 9 are closed by squeezing or pressing the clamping ribs 34 to their closed position corresponding to pos. 8 in FIG. 1, whereby the plate plates 5 are securely clamped, the beads 32 being pressed down into the surfaces of the plate plates. The sign is then finished and ready to be hung on the mast 3 by means of the brackets etc. 45th

14 DK 176166 B1 In this way, a sign of very solid structure is provided, using extremely few parts, namely only five main parts (two frame halves, two signboards 5, one boom 44), only four fittings (counter glass 50) and 5 only eight bolts 51.

By means of the lugs 47-49, which are welded to the boom 44 and which securely engage the groove 25 between the ribs 26, 27, an even very rigid and strong connection is obtained between the boom 44 and the sign 2, so that large 10 torsional loads whether the boom axis can be transmitted. This allows even large signs to be stably and securely held with only one boom 44.

In FIG. 4, the connection between the boom 44 and the lug parts 48, 49 is shown on a larger scale. Here is more clearly seen the solid engagement between the welding portions 48, 49 and the ribs 26, 27 on each side of the groove 25. The weld connections between the boom and the welding portions are indicated at 52.

In FIG. 6-8 another suspension form is shown in which a sign 2 is suspended on the front of a square mast 53.

The frame 4 of the sign 2 is held to the mast 53 by means of an upper angular bracket 54 and a lower angular bracket 55, each of which is fastened to the mast by bolts 56. On each angle bracket 54, 55 are projected in the form of two guide rails 57 ( can be seen most clearly in Fig. 8), which engages with the free edges 18, 19 of the opening 20 of the T-shaped groove 10 of the frame 4, thereby making the connection between the fittings 54, 55 and the sign very rigid with respect to torsional influences about the axis 53 of the mast, and the sign can therefore be tensioned asymmetrically on the mast, so that it protrudes further to one side than 30 to the other side, without the risk of the assembly breaking loose in windy weather or the like.

The frame 4 is fastened to the angular brackets 54, 55 with bolts 58 on which rotatable yokes 59 are welded. 8, that the yokes 59 are designed to resist rotation beyond the desired end position when the nut 58 of the bolt 58 is tightened. Therefore, the bolt should not be held against when the nut is tightened.

DK 176166 B1

Thus, in the design according to the invention of the profile 1, the dual advantage is obtained in this connection that the sign can be secured to a mast with only one set of fittings and that the sign is affixed in a simple and quick manner. At the same time, furthermore, the advantage is obtained that, thanks to the elongated, T-shaped groove 10, the sign is easily slidable in its suspension when the bolts 58 are released. This results in considerable relief, since the mast does not need to be placed very precisely in relation to the desired position of the signboard.

Through a system of holes, cables or wires can be drawn from the interior of the mast to the interior of the sign. Thus, there are coinciding holes in the mast 53 and in the one tab of the angular brackets 54, 55, and corresponding holes in the second tab of the angular brackets and the frame 4 at 61.

In FIG. 9, lifting of the sign according to the invention is shown with a specially designed scissor 62. When lifted with a crane in the eye 63 of the scissors 62, the two lower legs 66 of the scissors for spreading in the directions 65 are actuated, whereby the claws 67 get a firm 20 and secure grip under the frame profile. two rib-shaped projections 16, 17.

In FIG. 10, the use of an eye bolt 68 with two lugs 69 and 70 is shown to lift a sign 2 with a frame with the profile 1 according to the invention.

Thus, by providing the T-frame with the T-groove 10, significant relief and time savings are obtained by lifting signs 2 according to the invention during assembly, using adapted lifting gear which can be very quickly connected to the sign and removed again.
