Description

Device for driving traffic signs.

The invention relates to devices that facilitate traffic on the roads, and more particularly to devices for fastening road signs to pillars in the form of pillars. The term “road sign in this application means any information, including advertising, placed on a suitable basis, mainly on sheets of aluminum and aluminum alloys.

Known quick-detachable structures for attaching hinged shields that contain brackets associated with their holders through spring-loaded fixing bolts, mating with different diameters, fixed to the base of the rack, described in RF patent N2105837, E 01 F 9/011, publ. 02/27/98 in bull. N 6 and A.S. N 1344849, E 01 F 9/00, publ. 10/15/85 in bull. N38.

These columnar load-bearing structures with quick-detachable information boards are characterized by functionally unreliable fastening of the shield holders to the rack, since during operation the gaps and backlashes in the joints increase, leading to the caps overturning due to the arising painful moments from dynamic wind loads. The friction forces of the fasteners are not enough to fix the shields in the vertical plane due to the large windage of the shields, which makes them radially movable. This is unacceptable for road signs and signs: an arbitrarily rotated shield loses its information content without focusing on the consumer.

Description

There are various devices for attaching a road sign to a post with a clamp covering the pole together with an arm, to which, in turn, an information sign of the sign is attached.

Known kronshteyn-clamp, consisting of two split halves (patent US 5497973, publication 12.03.1996). Such devices are relatively difficult to manufacture and are suitable for mounting on poles of a narrow range of diameters.

The closest analogue to the claimed device is a multifunctional bracket containing several parts (see US 5503580, publication 03/31/1970). This device for attaching a road sign includes, inter alia, a collar having a flat platform for pressing the bracket of the road sign to the post. The disadvantages of this device include the complexity of the design, as well as the unreliability of fastening the road sign by means of a bracket, clamped between the clamp and the post, as a result of which there is the possibility for relatively easy unauthorized removal of the road sign. In addition, this design does not provide high wind resistance.

The technical task to be solved is the creation of a simple device design that provides reliable fastening of road signs to poles in order to prevent their unauthorized removal.

The problem is solved in that the device for fastening the road sign contains a clamp having a flat platform for pressing the bracket of the road sign to the post, which is made with a longitudinal protrusion, pressing the bracket of the road sign to the post, and the device is equipped with a U-shaped insert located between the post and the platform the clamp so that one of the bent ends of the liner abuts against the end surface of the clamp, and the other end serves as a stop for the bracket of the road sign.

in private versions of the utility model, the collar may consist of two halves interconnected by fasteners.

The clamp and liner can be made of steel.

The protrusion made on a flat clamping pad of the clamp ensures reliable pressing of the bracket profile to the post and prevents the sign from being removed under the action of forces applied in the transverse (horizontal) direction.

A U-shaped insert clamped between the flat area of the clamp and the pole serves as a stop preventing the removal of the mark under the action of forces directed in the longitudinal (vertical) direction.

The invention is illustrated by drawings.

In FIG. 1 (a, b, c) presents options for fastening a road sign using the proposed device.

In FIG. 2 shows a U-shaped insert.

On Fig.3 shows one of the halves of the clamp and its workpiece.

Figure 4 shows the second half of the clamp, its workpiece and the position of the half of the clamp on the post (cross section).

A device for attaching traffic signs (see Fig. 1) contains a clamp consisting of two halves 1, 2 connected by means of fasteners 3 (screw and nut). One of the halves of the clamp has a flat (straightened) part 4 (see Fig. 4), on which a protrusion 5, longitudinal with respect to the axis of the clamp, is made (see Figs. 1, 4).

Road sign 6 is connected, mainly by welding, with a bracket 7 made of the required aluminum profile (see Fig. 1 a, b, c).

In the gap between the flat (straightened) part 4 of the clamp and column 8, a U-shaped insert 9 is placed, which is pressed against the column 8 with its surface 10. The insert 9 has two ends -11, 12 bent at a right angle. One of these ends - 11 rests in the end surface of the clamp, and

the second 12 serves as a stop for the bracket 7, which is sandwiched between the flat surface of the clamp with the protrusion and the liner 9.

Figure 2-4 shows the characteristic dimensions for the elements of the proposed device.

To mount the sign on the pole, the sign bracket is placed in the gap between the U-shaped insert and the flat surface of the clamp in accordance with one of the schemes shown in FIG. 1 a, b, c. Next, produce a coupler of two halves of the clamp by means of a screw and nut. The sign is securely mounted on a post.
