Description

[0001] Temporary road

[0002] The subject of the invention is a temporary road, intended for deployment, in particular by unrolling from a winding drum, in areas lacking pavement, including wetland and sandy terrains.

[0003] From the prior art, temporary roads are known that are composed of panels connected into a chain-like structure, wound onto a rotatable winding drum or rolled into a coil without such a drum. Furthermore, devices for deploying such roads are also known, for example from European patent publications EP 1003936 Bl, EP 3176116 Bl, and EP 3792400 Bl, as well as from the U.S. patent publications US 4681482 A.

[0004] From Chinese utility model description CN 210368498 U, a temporary road in a coil is known, composed of panels connected at the top by linking straps and at the bottom by a lining, wherein a gap is formed between each pair of adjacent panels.

[0005] From Chinese utility model description CN 203440726 U, a temporary road is known, composed of multiple panels, each of which is provided, on one of its longer sides, with a socket and, on the opposite side, with a projection fitted into said socket, wherein the projection has an L-shaped cross-section. Each of the panels has a flat upper surface and reinforcing ribs on the bottom side, the ribs having either a trapezoidal or rectangular cross-section.

[0006] From German patent description DE 2248321 B2, a temporary road is known, composed of plates provided with complementary, form-fitting connecting elements in the region of opposite longitudinal edges. The connecting elements form press-fit joints, which consist of cylindrical protrusions or grooves enclosing said protrusions. Furthermore, from this patent specification, a device for deploying a temporary road is also known, in the form of a bearing-mounted roller attached to the cargo surface of a vehicle.

[0007] From European patent application EP 4347950 Al, a temporary road is known, composed of multiple panels reinforcing the surface, and of connecting elements adapted to join said panels. The road is deployed from a cylindrical roll. The panels are perforated and comprise arms on their longer sides, wherein the arms on a given side are provided with coaxial through-holes oriented parallel to said side. The panels are hingedly connected to one another by means of connecting rods inserted into the holes of their arms.

[0008] From international patent application WO 2019229474 Al, a temporary road is known, composed of panels having a flat working surface and an opposite corrugated surface. Each panel is provided, on one of its longer sides, with a female connector end, and on the other side, with a male connector end.

[0009] In known solutions relating to temporary roads composed of interconnected longitudinal panels that can be unrolled from a winding drum, a problem arises involving the displacement of the panels relative to one another along their longer edges, as well as their shifting relative to the ground, which occurs particularly over longer road sections and is undesirable in many applications. Furthermore, there are limitations regarding the achievable width of the usable surface.

[0010] A temporary road, comprising longitudinal rectangular panels connected to one another along their longer edges, wherein one of the longer edges of a given panel is provided with a socket and the opposite edge with a projection, the projection of the given panel being hingedly mounted in the socket of the adjacent panel, and wherein each panel has, on one side between the edges, a first working surface and, on the opposite side, a second working surface, characterized in that each panel comprises a spring-loaded pin, the tip of which extends from the interior of the panel through a through-hole in the inner wall of the socket, wherein the projection of each panel, when inserted into the socket of the adjacent panel, has a recess on its outer surface, and the working end of the spring-loaded pin is pressed against said recess.

[0011] Preferably, each panel comprises, on one of its shorter edges, a first connector protruding from the panel on the side of the first working surface, and a groove located on the side of the second working surface, said groove being parallel to the shorter edge; and on its other shorter edge, each panel comprises a second connector protruding from said edge on the side of the second working surface of the panel, and a groove located on the side of the first working surface, said groove being parallel to said shorter edge.

[0012] Further advantages are obtained if the panels comprise anchoring holes.

[0013] The solution according to the invention enables easy connection of two or more rows of temporary roads, thereby multiplying its width. Parallel sections of the roads overlap with their connectors, which allow for a form-fit connection of these sections. The invention also allows for the connection of road sections arranged perpendicularly to one another, using the sockets located on the longer edges of the panels and the connectors positioned on the shorter edge of the perpendicular section. Thanks to the anchoring holes in the panels, the road can be stably secured to the ground. The deployed temporary road maintains a stable shape, the panels remain in an orderly alignment, and are well secured against lateral displacement. A section of the temporary road may be wound into a coil on a winding drum, and its usable surface area, once unrolled, may reach up to 150 m2with a length of 50 m, wherein the length and width - and thus also the surface area - of the road can be freely increased by connecting it with other sections. Thanks to the use of anodized aluminum panels, the solution is fully resistant to corrosion and thus suitable for harsh weather conditions.

[0015] The temporary road according to the invention, in the embodiment, comprises longitudinal anodized aluminum panels 1, each of which has a socket 2 on one of its longer edges and a projection 3 on the other edge. A projection 3 of a panel 1 adjacent to a given panel 1 is hingedly mounted in the socket 2 of the given panel 1, wherein each projection 3 has two recesses 4 on its outer edge. Furthermore, each panel 1, on the side of the socket 2, comprises two spring-loaded pins 5, whose working ends protrude through through-holes 6 in the inner surface of the socket 2, wherein the spacing of the through-holes 6 on the inner surfaces of the sockets 2 corresponds to the spacing of recesses 4 on the outer surface of the projection 3, and the working end of the spring-loaded pin 5 is positioned inside the recess 4. Furthermore, panel 1 comprises a first connector 7, which is detachably connected thereto on one of its shorter edges, wherein the first connector 7 protrudes from said edge on the side of the first working surface la of panel 1 and comprises a groove located on the side of the second working surface lb, said groove being parallel to said shorter edge. On the opposite shorter edge of panel 1, a second connector 8 is detachably connected thereto, which protrudes from said edge on the side of the second working surface lb of panel 1 and comprises a groove located on the side of the first working surface la, said groove being parallel to said shorter edge. Each panel 1 comprises longitudinal ridges 9 parallel to the longer edges of panel 1 on both its first working surface la and its second working surface lb. A first ramp strip 10 is connected to the outermost panel 1, which has a projection 3 on its outer edge, wherein the first ramp strip 10 comprises a channel 11 on the side of the projection 3, in which the projection 3 of the outermost panel 1 is seated. On the side of the second of the outer panels 1, a second ramp strip 12 is connected thereto, which on the side of the socket 2 of that panel 1 has a tongue 13 seated in said socket 2. Each panel 1 has two anchoring holes 14, one located near one of its shorter edges and the other near the opposite shorter edge. Each projection 3 has a thickened edge on the side inserted into the socket 2, wherein the socket 2 has a slit along its entire length, the width of which is smaller than the width of the thickening on the projection 3. The panels 1 are hollow inside and comprise longitudinal reinforcing ribs 15. The spring-loaded pin 5 is mounted in a guide hole within the reinforcing rib 15, which is located on the side of the projection 3. Furthermore, the spring-loaded pin 5 comprises a rod 16 oriented perpendicular to the axis of the spring-loaded pin 5. Between the reinforcing rib 15, in which the guide hole is formed, and the rod 16, there is a compression spring 17 mounted coaxially on the pin, wherein the rod 16 has one end facing the first working surface la and the other end facing the second working surface lb, and wherein panel 1 comprises longitudinal holes 18 aligned in the same plane as the spring-loaded pin 5 — one located on the side of the first working surface la and the other on the side of the second working surface lb — and the ends of rod 16 are seated in these longitudinal holes 18, wherein the length of the longitudinal hole 18 defines the stroke of the spring-loaded pin 5. The thickness of each of the connectors 7, 8 in the groove area is smaller than the thickness of the slit in the socket 2, whereas on the outer edge parallel to the groove, the thickness of each of the connectors 7, 8 is greater than the width of the slit in the socket 2, which enables the connection of separate sections of the temporary road arranged perpendicularly to one another.
