MARKER

Abstract: Marker comprising a trilateral hollow pyramid the sides of which each consist of a rigid triangular plas­ tic panel (10, 11, 12). The side edges of one of said panels is connected by hinges (19) each to one (10) side edge (14, 15) of the other two (11, 12) of said panels, which are releasably interconnected at the other side edges thereof.

Description: The invention relates to a marker, comprising a trilateral hollow pyramid. The marker of the invention is intended for use as a traffic sign on streets, roads and open places in or­ der to define an area from which traffic should be ex­ cluded for one reason or the other. It is also intended to be used as a sign indicating danger or other condi­ tions that should be observed by the public, or indicat­ ing a route to be followed by the participants of sport contests and similar events. The purpose of the invention is to provide a marker which can be easily handled and can be easily adapted to the intended use thereof and which can be stored in a compact condition so that a number of markers can be carried in a car without requiring a lot of space there­ in. According to the invention, the related purpose is achieved by providing a marker of the kind referred to which is characterized by the features of claim 1. In order to illustrate the invention an embodiment of the marker according to the invention will be de­ scribed in more detail below, reference being made to the accompanying drawings in which FIG. 1 is a plan view of the marker in an unfolded flat condition, FIG. 2 is a fragmentary side view of two adjacent panels of the marker with a hinge mounted therebe­ tween, FIG. 3 is a perspective view of a hinge element, FIG. 4 is a cross-sectional view of a hinge element mounted to two adjacent panels, FIG. 5 is a plan view of the marker folded up for storage, FIG. 6 is a perspective view of a marker in the op­ erative condition, FIG. 7 is a perspective view of a connection strap, FIG. 8 is a fragmentary side view of two adjacent panels of the marker interconnected by the connect­ ing strip of FIG. 7, and FIG. 9 is a perspective view of the marker mounted to a tripod stand on the top thereof. The marker shown in the drawings comprises three identical triangular panels, a central panel 10 and two side panels 11 and 12, which are made of a rigid plastic material such as polypropylene, in a suitable colour. Each panel has a base edge 13 and two side edges 14 and 15, and pieces 16 of a light-reflecting material is at­ tached to one or both sides thereof. Also a suitable text 16', FIGS. 6 and 9, of a light-reflecting material can be arranged on the panels. The apex between the side edges 14 and 15 of each panel is cut off at 17, and at this apex each panel has an aperture 18. At the side edges 14 and 15, the central panel 10 is jointed to the adjacent side edges 14 and 15 of the side panels 11 and 12 by means of hinges 19. These hinges can comprise a thin web of the same plastic ma­ terial as that from which the panels are made, said web being integral with the panels jointed by the hinge, but it is preferred to arrange the hinge as is shown in FIGS. 2 to 4. The hinge shown therein comprises an S-­ shaped element 20 of strip material, which is engaged with slots 21 in the panels to be jointed, said slots extending along the adjacent edges. A hinge of this type provides the advantage over the web connection mentioned above, that the jointed panels can be easily disconnect­ ed should it be necessary for one reason or the other to replace a panel. For storage of the marker this can be folded up by folding the side panel 11 against one side of the central panel 10 and the side panel 12 against the other side of the central panel 10 such that the marker will appear as disclosed in FIG. 5. In this folded up condi­ tion, the marker can easily be stored and requires a small space only, and it is also possible to hang up one or several markers on a hook or other suspension means by passing such hook or means through the apertures 18 in the three panels registering with each other. When the marker is to be used it is folded to form a trilateral hollow pyramid as shown in FIG. 6. In order to maintain the marker in the pyramid shape a connection means for interconnecting the free edges 14 and 15 of the side panels 11 and 12 is provided. In the embodiment shown, such means comprises a strap 22, FIGS. 7 and 8, of a flexible and elastic rubber or plastic material, which forms a head 23 at one end thereof and a grooved tab 24 at the other end thereof. On opposite sides of the strap there are formed mutually spaced cross ribs 25, the ribs on one side of the strap being displaced longitudinally in relation to the ribs on the other side of the strap. The strap is passed through a slot 21 in one of the side panels such that the head 23 engages one side of the panel, the head being too large to pass through the slot, and when the marker has been folded to form the pyramid the strap is passed through the corre­ sponding slot 21 in the other side panel and is pulled tight by gripping the strap at the tab 24. Then, it is possible to draw the adjacent edges tightly together and to lock the strap in the tightened position by one cross rib or the other engaging the edge of the slot in said other side panel. The pyramid obtained will be very sturdy and rigid and can be positioned on the ground resting at the base edges 13, but it is also possible to mount the pyramid as a cap on top of a tripod 26 as is shown in FIG. 9. Preferably, the legs of the tripod are adjustable as to the length thereof. Due to the cut off of each panel at 17 there is a through opening 27 in the top of the pyramid, and a stick or bar can be passed through this opening and be driven down into the ground, and it is also possible to use the opening for mounting a lantern to the top of the pyramid. It should be noticed that the pyramid can be formed with either of the two sides of the panels facing out­ wards, which means that two different decorations of the marker can be obtained if the decoration of one side of each panel is different from the decoration of the other side of the panel. Thus, the appearance of the marker can be adapted to two different purposes of use.

Claims: 1. Marker comprising a trilateral hollow pyramid, characterized in that the sides (10, 11, 12) of the pyramid each consist of a rigid triangular plastic panel, the side edges (14, 15) of one (10) of said panels being connected by hinges (19) each to one side edge of the other two (11, 12) of said panels, and that means releasably interconnects said latter panels at the other side edges thereof. 2. Marker as claimed in claim 1 wherein the hinges (19) between the panels (10, 11, 12) comprise S-shaped links (20) received by slots (21) in the panels, extend­ ing along the edges thereof. 3. Marker as claimed in claim 1 or 2 wherein said means comprises an elastic strap (22) having a head portion (23) at one end thereof and cross ribs (25) mutually spaced longitudinally of the strap, said strap being passed through slots (21) in the panels, extending along said other edges. 4. Marker as claimed in any of claims 1 to 3 wherein light-reflecting material (16, 16') is provided on the outside surface of at least one of said panels (10, 11, 12). 5. Marker as claimed in any of claims 1 to 4 wherein each panel (10, 11, 12) at the top apex thereof forms an aperture (18). 6. Marker as claimed in any of claims 1 to 5 wherein the pyramid is truncated to form at the top thereof an opening for the passage of a stick, for mounting a lantern or for similar purposes. 7. Marker as claimed in any of claims 1 to 6 fur­ ther comprising a tripod stand the upper portion of which is received inside the marker which forms a cap on top of the tripod stand.
