Description

The invention relates to a device for information or information signs on thoroughfares and. Like., Which has a surface mounted on a panel-like unit, carried by one or more posts, indicating or indicating, the panel-like unit made of a substantially flat sheet metal, which has a lower flange formed transversely to the sheet metal, and a profiled sheet arranged between the sheet and the post.

Freestanding signs for informational purposes. These, especially on thoroughfares, are nowadays usually made up of a number of U-shaped or box-shaped profile sheets, which are screwed together using profile flanges, which are mounted on rigid pipe constructions and have a sufficient sheet thickness so that the profiles can absorb moments of force. The manufacture of such signs is expensive and, furthermore, the assembly is time-consuming, but despite the complicated structure, they have little resistance to impact loads, for example when clearing snow. From the point of view of traffic safety, the signs available today are not acceptable because if they are hit by a motor vehicle, they can severely damage both the vehicle and its occupants, since the relatively coarse sheet metal gives a large amount of plasticizing energy, which is approximately proportional to the square the thickness is, and when moving to a post, the entire shield device is pulled down. The U-shaped profile sheets, which are firmly connected with rigid pipe structures, have a high degree of rigidity and against unnecessarily high plasticizing energy when the sign is hit and destroyed. It has long been sought to create a board of the type mentioned, which is sufficiently stable to withstand wind loads and stresses that arise during snow removal, but nevertheless yields gently when starting off.

The invention has for its object to provide a plasticizable, resilient shield device of the type mentioned that yields despite stiffness compared to usual loads when starting.

The shield device according to the invention is characterized in that a flat and a profiled sheet form together a cassette-like unit which, alone or together with at least one further unit, forms the sign that the flat sheet serves as a stop at its edges, bent and open to the middle of the sheet has forming parts, which are arranged to accommodate the edges of the profiled sheet extending parallel to the profiling, that the free distance between the stops of the flat sheet formed by the bottom of said grooves is smaller than the width of the profiled sheet, calculated transversely to the profiling in the non-actuated position of said sheet, that the profiled sheet is clamped by compression transversely to the profile between said stops of the flat sheet, whereby the flat sheet is stretched in the transverse direction, and that on the extending transversely to the first-mentioned edges Edges of the flat sheet metal are arranged which surround the edges of the profiled sheet metal which are oriented transversely to the profiling and hold the profiled sheet metal in contact with the flat sheet metal sheet.

The shield device can consist of one or more cassettes, each of which is made up of a shield part made of mainly flat sheet metal and a sheet metal that supports and profiled in the longitudinal direction of the shield, the profiling being, for example, corrugated or trapezoidal. The shield part can consist of a sheet metal, which is bent along its ends extending transversely to the profiling, around or immediately outside the ends of the profiled sheet metal, in order to support the support effect of the profiling, so that the shield part is given a support during the bending , which protects the susceptible ends of the profiled sheet from damage and, due to the stiffening carrier effect which the shield plate receives from the bending, results in a static interaction between the individual partial profiles acting as a carrier. The ends of the shield plate which are parallel to the profiling are bent around the corresponding edges of the profiled plate in such a way that an edge is formed which serves as a support for the construction carrying the cassette, for example consisting of posts. The support can be attached in such a way that the cassette and thus the label cannot be moved up or down. However, it is an advantage if this attachment is carried out so that a relative movement between the post and the cassette or the shield is possible; for example, the attachment from the post is carried out as an upwardly open hook, because a soft post carrying the sign and mounted in the attachment can then be torn out of its attachment without the sign being pulled down if there are at least three posts.

The edges of the profiled sheet metal which are parallel to the profiling can expediently be given a bend which is mainly uniform with the bend of the shield sheet, which increases the force of the fastening against the construction carrying the cassette. This bend can advantageously be given a groove-shaped design so that the adjacent cassettes contained in the shield are supported and guided against one another. The profiled sheet in its direction transverse to the profiling preferably has a dimension that is somewhat larger than the dimension in the same direction that the shield sheet has between the inner edges of its bends. The profiled sheet is inserted into the shield plate in a position bent transversely to the profiling and then pressed against the shield plate. The profiled sheet is elastically compressed transversely to its profiling and thereby gives the shield sheet that receives it a stabilizing tensile stress. The longitudinal profiling prevents denting. The force required to keep the plate pressed together can be generated in various ways, for example by riveting against the shield plate or by bending the edges of the shield plate around the ends of the profiled plate which lie transversely to the profiling, or by the fact that the cassette the assembly on the load-bearing structure, for example consisting of posts, is pressed against it.

The above-mentioned bending of the shield plate, at least in its direction parallel to the profiling, forms the support on a structure supporting the shield, for example a soft post.

The profiling makes it possible to mount a protruding part on the post, so that this at least to a certain extent fills a trough of the profiled sheet. The protruding part should preferably correspond to a trough in the lower part of the lower cassette. The protruding part prevents the sign from being lifted up, for example in the case of an upward wind load component, or that if the exterior is approached and knocked over by several posts and thereby detaches from its hook fastenings, the board in its vertical plane moves from that acting on the sign frictional forces of the overturned post directed downward. When moving off, the soft post is then only bent in its lower part, the protruding part attached to the post letting go of the trough that receives it, after which the post is pulled down by the approaching motor vehicle and the post is fastened in the cassette as a result of the hook effect described above solves.

Larger orientation signs are almost always strived for. These struts can be pulled down when starting and penetrate into the starting motor vehicle. To prevent this, the strut is attached to the post so that it detaches from the attachment to the post. For this purpose, the upper part of the post is provided with a sleeve which does not completely enclose the strut, the only connection of which to the strut consists of one or more clamped locking plates which are inserted into grooves which are common to the strut and the sleeve and are dimensioned in such a way that that the bracing forces can be transmitted together with the design of the groove. When moving off, the soft post is pulled down, with a bending moment occurring between the sleeve and the strut. The sleeve, which does not completely enclose the strut, is torn open and bent outward from the strut, and the locking plate connection between the sleeve and the strut is released. The post can now be pulled down without pulling the strut, which remains roughly in its original position during the start.

The invention is described in more detail with reference to the drawing which illustrates an exemplary embodiment. Show it

• Fig. 1 is a front view of a shield, Fig. 2 is a section along the line AA in Fig. 1, Fig. 3 is a section along the line AA in Fig. 1, but in an alternative embodiment, Fig. 4, the assembly of the trapezoidal sheet in Shield plate, Fig. 5 is a section along the line BB in Fig. 1, Fig. 6 is a side view of the support of a cassette on the attachment and the execution of the edge bends of both the shield plate and the profiled plate, Fig. 7 is a side view of the anchorage of the lowest cassette against horizontal forces, Fig. 8 shows a side view of a part of the post with a projecting part mounted thereon, Fig. 9 shows a side view of the bracing attachment on the post, Fig. 10 shows a section along the line CC in Fig. 9, Fig. 11 den Course when starting by a motor vehicle, the shield being seen from the side, FIG. 12 a part of the sleeve, FIG. 13 an embodiment of a locking plate, and FIG. 14 another embodiment m of the locking plate.

The panel or sign device shown in FIG. 1 consists of a sign made up of three cassettes 2 on three posts 1. The cassettes 2 each consist of a shield plate 3 and a profiled plate 4, in this case a trapezoidal plate.

From Fig. 2 it can be seen that the shield plate 3 is bent around the profiled plate 4 and in this way brings about the pressing of the profiled plate 4 against the shield plate 3.

From Fig. 3, which shows the alternative case that the shield plate 3 is bent just outside the profiled plate 4, it can be seen that the profiled plate can be inserted in this case after the bending of the shield plate 3 along the edge, which is transverse extends for profiling the profiled sheet, which is a manufacturing advantage in certain cases.

Fig. 4 shows how the trapezoidal sheet 4 is excessively bent in relation to the shield plate 3 and pressed against the shield plate 3, so that the shield plate in the finished cassette is stretched by the pressure load which arises from the elastic pressure which arises when compressed transversely to the longitudinal direction of the profile Properties of the trapezoidal sheet 4 originates.

In the section shown in Fig. 5, the end position of the compressed profile sheet in relation to the post 1 is illustrated.

Fig. 6 shows partly how a cassette is placed on a mounting 5 in the form of a hook, the is attached to the post 1 by means of a loop clamp or a similar, band-shaped fastening member 6, and in part the designs of the bends of the shield plate 3 and of the profiled plate 4 along the edges, which are parallel to the profiling of the profiled plate, and how these are used for mutual guidance of the subsequent cassettes with locking are executed.

In the same way, FIG. 7 shows how the lowermost cassette is anchored against horizontal force from the rear of the plate with a soft hook support 7, which is therefore soft so that no damage to the motor vehicle that is about to start should occur. The soft hook support 7 also functions as a preliminary vertical support when installing the first (lowest) cassette.

The protruding part 8 shown in Fig. 8, mounted on the post 1, is adapted such that it partially fills a trough in the trapezoidal sheet 4 and thereby forms a barrier against such mutual displacement between the post and the panel, which is caused by normal forces, i.e. Wind power, snow splashes when clearing snow and. Like., is caused. Part 8 is also intended to prevent the position of the sign from changing in relation to the other posts when one of several posts carrying a sign is moved up and down. The part 8 consists in this case of a bent sheet metal attached to the post 1 by means of hose clamps 6 or the like.

The posts 1 are provided with struts 9, and FIG. 9 shows the attachment of these struts to the post by means of a sleeve 10 which is not closed. In the case shown, the strut has a hexagonal cross section. The sleeve 10 is locked against normal force against the strut 9 by means of a locking plate 11, which is shown in FIGS. 13 and 14 in two different embodiments. The locking plate is pressed into slots arranged on the sleeve 10 and the strut 9, the locking plate 11 being clamped against the inside of the slots. The sleeve 10 is connected to the post 1 via a link 13 and a flat steel 14 by means of hose clamps 6 or the like.

The locking plate 11 shown in FIG. 13 is provided with a bead 12 which decreases in the longitudinal direction and which causes a clamping force against the inner sides of the slots.

In the embodiment of the locking plate 11 shown in FIG. 14, the clamping force is brought about in that the plate is pre-bent in a weak arc shape.

Fig. 10, which shows a section along the line C-C in Fig. 9, shows how the locking plate locks the strut and the sleeve.

The course when a motor vehicle approaches one of the outer posts 1 is illustrated in FIG. 11. The protruding part 8 attached to the post 1 has left its position in the profile valley and thereby enables the hooks 5 to leave their position engaging with the shield when the post 1 is pulled down, and that the sleeve 10 is released from the strut 9.

Only the approached post is pulled down and the sign is held on the other posts by means of the hooks 5 and the projecting parts 8, which parts are still engaged with their troughs.

Fig. 12 shows on a larger scale and in detail how the sleeve 10 has been torn open and has come loose from the strut 9, the locking plate 11 having lost its engagement with the strut 9. The hooks 5 and the protruding parts 8 on the remaining posts prevent the sign from falling down and swinging in its own plane.
