Definitions

  • the present invention concerns a collapsable guide sign which is placed in plurality on a road or a parking place and used as a traffic control guide sign or a road guide sign for inhibiting passage or regulating the direction of passage of vehicles and pedestrians, placed in buildings such as hotels and used as a guide sign for a meeting place, or used as a signpost of a shop, as well as usable as a pedestal for a support for setting up a flag or a streamer.
  • the colored cone comprises a cone 40 like that a cone-shaped hat, and a square base 41 protruded horizontally like a flange at the periphery of the lower end thereof which are integrally molded from a red-colored plastic material in a steric configuration.
  • Such colored cones used popularly molded entirely from the plastic material have a merit that they can be transported to and used as they are in the site of use but have a drawback that they are inconvenient to transport or store because of their large and bulky shape.
  • cones are stacked in a plurality of stages by inserting one cone 40 into another, since only a limited number of them can be contained in the trunk of a common passenger car, a patrol car dispatching for an inspection spot of a traffic accident or a patrol car going to a spot of traffic inspection can not carry the cones by a quantity required for the spot, to bring about inconvenience that they have to be transport by using another vehicle.
  • a guide sign as shown in Figs. 8 and 9 in which a support post 51 formed as a telescopic structure like that a joined fishing rod comprising a plurality of pipes 52, 53 and 54 of different diameters disposed at the center of a base 50 of a square plastic plate.
  • a cone 55 made of a sheet formed as a conical shape is put over the support post 51, with the upper end of the cone 55 being secured by a cap 56 capped to an upper end of the support post 51, and the lower end of the cone 55 being secured to the base 50.
  • the support post 51 is extended as shown in Fig.
  • the guide signs having the support post 51 protruded above the base 50 can not be stacked in plurality as those used popularly shown in Fig. 6 but have to be transported or stored merely in a gathered state. After all, they have a serious drawback of rather making transportation or storage inconvenient and have not yet been put to practical use.
  • a technical object of the present invention to provide a collapsable guide sign which can be simply collapsed or assembled, can be assembled into a sterical shape like that a cone and set up during use, and can be collapsed flat during transportation or storage into a structure capable of being housed in an extremely compact manner.
  • a collapsable guide sign assembled substantially into the shape of a triangular pyramid in use wherein two planes among three planes in adjacent with the apex P of the substantially triangular pyramid, are formed each with an integral plate, respectively, the integral plates being connected inwardly collapsably, and the remaining one plane has bisected plates split substantially in a right-to-left symmetrical shape and connected collapsably with each other, each of the bisected plates being connected inwardly collapsably to each of the in adjacent respectively.
  • collapsable guide sign of the present invention since it is assembled into the sterical shape of the substantially triangular pyramid in use, it is highly stable and is not easily turned down even when a strong window is blown from any of directions. Further, each of the planes in adjacent with the apex is formed as a flat surface, characters or figures can be applied simply on the surface, as well as large characters or figures indicated thereon can be shown in a complete form when the guide sign is directed to the front.
  • suspending strap serving as a grip when suspending strap serving as a grip is laid around from the inside of the substantially triangular pyramid between a pair of strap passage holes perforated in an upper portion for each of the bisected plates substantially at the same height, and a pair of strap passage apertures perforated each in an upper portion for each of the integral plates substantially at the same height and at a position higher than that for each of the strap passage apertures in the bisected plate, if the guide sign is merely raised by gripping the suspending strap, both ends of the bisected plates are pulled inwardly by the suspending strap, by which the bisected plates are collapsed and, at the same time, the integral plates connected respectively therewith are collapsed inwardly so as to approach with each other.
  • each of the integral plates and the bisected plates may be connected by means of hinges, and a spring hinge is used for at least one of them such that both sides closed inwardly when the substantially triangular pyramid is collapsed are biased to open outwardly.
  • Fig. 1 is a perspective view illustrating a preferred embodiment of a collapsable guide sign according to the present invention
  • Fig. 2 is a perspective view illustrating the state of folding the guide sign
  • Fig. 3 is an explanatory view illustrating a state in the course of assembling the guide sign

  • reference numeral 1 denotes a collapsable guide sign which is used being assembled as a cylindrical substantially triangular pyramid with no bottom.
  • two plane S 1 , S 2 are formed with integral plates 2, 3 respectively, with the integral plates being inwardly collapsably connected with each other at the hinge 4.
  • the remaining one plane S 3 has bisected plates 5R, 5L split substantially into a right-to-left symmetrically shape, and the bisected plates 5R, 5L are connected to each other by means of hinges 6, 6.
  • Each of the bisected plates 5R, 5L is connected to each of the adjacent integral plates 2, 3 respectively so as to be collapsed inwardly by hinges 7, 8.
  • each of the planes S 1 - S 3 in adjacent with the apex P of the guide sign 1 is recessed arcuately at a lower end edge of each of the integral plates 2, 3 and bisected plates 5R, 5L such that pedestals 9, 9 are formed on both ends at the bottom of each of the surfaces forms.
  • the guide sign 1 can be stood stably on three-point supports by each pedestal 9, for example, even on uneven road surfaces.
  • an anti-slip rubber 10 is attached to the pedestal 9 such that the rubber protrudes to the outside of the triangular pyramid and such that a weight can be placed on the rubber 10.
  • the integral plates 2, 3 and the bisected plates 5R, 5L are made of a plastic material such as polyvinyl chloride, polyethylene or regenerated plastics.
  • a plastic material such as polyvinyl chloride, polyethylene or regenerated plastics.
  • letters or figures can be applied as markers, the surface of the plates can be formed partially or entirely with a reflector plate, or a reflection seal can be appended.
  • each of the plates 2, 3 and 5R, 5L is cut at the top end thereof such that when they are assembled into the triangular pyramid, an insertion portion 13 may be formed at the periphery of the apex P for inserting and attaching a signal light 12 or the like.
  • a suspending strap 14 that serves as a grip is laid around from the inside of the triangular pyramid between a pair of strap passage holes 15R, 15L each perforated in an upper portion for each of the bisected plates 5R, 5L substantially at the same height, and a pair of strap passage holes 16, 17 perforated in an upper portion for each of the integral plates 2, 3 substantially at the same height and at a position higher than that for each of the strap passage apertures 15R, 15L.
  • each of the bisected plates 5R, 5L is flexed at the hinge 6 and the integral plates 2, 3 connected by way of hinges 7 and 8 to the bisected plates 5R, 5L, respectively are flexed at the hinge 4, and the guide sign 1 is collapsed automatically.
  • the hinge 4 for connecting the integral plates 2, 3 to each other and the hinges 7, 8 for connecting the integral plate 2, 3 with each of the bisected plates 5R, 5L are made of a hard rubber.
  • a spring hinge 7a which is biased in the direction of outwardly opening both sides closed inwardly when the triangular pyramid is collapsed, is used to at least one of the hinges 4, 6, 7 and 8, for example, one of the hinges 7 connecting the integral plate 3 and the bisected plate 5L.
  • the present invention has a constitution, for example, as described above and the operation will be explained next.
  • the integral plate 3 and the bisected plate 5L are expanded by the resilient force of the spring hinge 7a and, accompanying therewith, other integral plate 2 and the bisected plate 5R are also expanded automatically, so that the guide sign 1 is gradually expanded into the shape of the triangular conical shape as shown in Fig. 3, and the guide sign 1 can be set up extremely simply with no other particular operation.
  • the guide sign 1 is assembled such that it is supported on three points by the pedestals 9 of the triangular pyramid, the guide sign can be set up stably even if unevenness is present such as on the road surface and it is less turned down even if a window is blown strongly from any direction.
  • the guide sign can be used as a night guide sign by inserting a grip portion of the signal light 12 into the insertion portion 13 and lighting up the signal light 12 during night.
  • each of the plates 2, 3, 5R and 5L of the guide sign 1 are made of a plastic material of relatively high light transmittance and when the lighting portion of the signal light 12 is inserted into the triangular pyramid of the guide sign 1, the guide sign 1 can be lit up entirely.
  • the guide sign is formed not into the shape of a circular cone but a triangular pyramidal shape upon assembling in which the three planes S 1 - S 3 are in adjacent with the apex P, marks different from each other may be applied to each of the planes S 1 - S 3 of the triangular pyramid (for example, rightward arrow, leftward arrow or inhibition of entrance). Then, when they are arranged with a mark intended to be shown being positioned at the front as shown in Fig. 4, various kinds of traffic controls can be conducted by using only one kind of a guide sign by merely changing the way of placing.
  • each of the planes S 1 - S 3 is flat, characters or figures can be simply indicated, for example, by printing on the surface and the characters, etc. can be recognized visually in a complete state as viewed from the front, so that a large characters and figures can be indicated extremely easily to see and the content of the mark can be seen easily even from a distance, which is a greatest merit of the guide sign.
  • the present invention is not restricted only to the embodiments described above but it may be modified, for example, as shown in Fig. 5, having no suspending strap 14 as a grip, or having no arcuate recess formed to the bottom of each of the planes S 1 - S 3 Further, use of the spring hinge 7a may be saves.
  • connection rods 20 if a plurality of guide signs 1 are connected by means of connection rods 20 to each other, each of the guide signs 1 can be set up more stably.
  • the connection rod has rings 21 formed on both ends, and the ring 21 has a rotational disc 23 mounted rotably with a triangular insertion aperture 22 being formed therein for insertion of the apex P of the guide sign 1, such that the guide signs 1 can be connected being faced in an optional direction.
  • Fig. 6 shows a further embodiment in which the guide sign 1 can be collapsed/set up by remote control.
  • Those portions in common with Fig. 1 carry the same reference numerals for which detailed explanations are omitted.
  • the guide sign 1 of this embodiment is rotatably connected by one integral plate 3 to the base 25 at the bottom thereof as a rotational axis by a motor 26.
  • each of the bisected plates 5R, 5L is collapsed by the own weight of other plates 2, 5R, 5L and, at the same time, the integral plate 2 connected therewith is collapsed so as to approach the integral plate 3, so that the guide sign 1 is collapsed inwardly flat against the resilient force of the spring hinge 7a.
  • each of the plates 2, 3, 5R, 5L may be connected collapsably by rings, or a plastic plate having a shape of developing a triangular pyramid shape may be bent into the form of a cylindrical triangular pyramid and connecting only the beginning edge and the terminal edge with hinges or spring hinges.
  • the guide sign 1 according to the present invention can be used not only as a guide sign but also as a pedestal by inserting and supporting, for example, a support post for a sign board or a flag into an insertion hole 13 at the periphery of the apex P in a case of window campaign for sales promotion.
  • the guide sign since the guide sign is assembled into the shape of a substantially triangular pyramid during use, it can be set up stably, for example, on a road surface, as well as characters or figures can be applied simply on the surfaces since they are formed flat and, in addition, large characters can be applied and seen easily even from a distance since they can be visually recognized in a complete form when viewed from the front.
