Description

Technical Field

[0001] This invention relates to an assembled sign in the shape of a triangular pyramid and a base material for an assembled sign in the shape of a triangular pyramid, rather than a conical cone shape.

Background Art

[0002] When it is necessary to draw people's attention, for example, signs are one of the tools for transmitting information by attracting people's attention. For example, at construction or work sites, cone-shaped signs may be used to indicate areas where entry by workers and others is prohibited.

[0003] In addition, signs may also be used (placed at a predetermined location) from the perspective of improving safety awareness at the site. For example, as part of hazard prediction (KY) activities, signs may be used to display items that require attention, such as today's hazard points, in order to make potential dangerous or harmful items apparent and inform workers.

[0004] Such signs are not usually permanently installed, often because of limited on-site space. Each time they are used, they need to be carried into the place of use and arranged, and after use, they need to be carried out of the place of use and returned to a predetermined location. Therefore, the more signs are used, the more difficult it is to transport them. Also, the storage space tends to increase. Considering the above circumstances, a collapsible cone-shaped sign (for example, Patent Document 1) has been proposed.

[0005] Among conventional cone-shaped signs described in such prior publications, although some are configured to be deformable into a more compact form than when in use by folding when not in use, there is still room for further improvement in terms of transportation and storage. In the first place, in order to make a collapsible cone shape, the shape of the base material becomes complicated, and inevitably, there is a problem that thickness occurs in the folded state.

[0006] Furthermore, when attempting to actively utilize markers from the perspective of improving safety awareness on site, it becomes necessary to prepare a large number of markers because the effectiveness of notifying people of dangerous points is diminished if a sufficient number are not installed. However, conventional markers are not always easy to transport or store, making it difficult to actively utilize them, and thus there is little motivation to use markers from the perspective of improving safety awareness on site.

[0007] Furthermore, in recent years, as technologies to achieve the same objective, assembly-type markers and base materials for assembly-type markers (for example, Patent Document 2) have been proposed.

[0010] [Patent Documents]

[0011] [Patent Document 2] Japanese Patent Publication No. 2018-71105 [Overview of the project] [Problems that the invention aims to solve]

[0012] However, while Patent Document 2 does describe a base material for an assembly-type signage device that is composed of flat plates, its assembly requires complex work and is by no means suitable for on-site work.

[0013] The root cause of this problem seems to be that all the technologies were fixated on assembling "cone-shaped markers." Furthermore, it was pointed out that "cone-shaped markers" are inherently vulnerable to wind and can be washed away by flowing water during floods, and there was a strong demand for a fundamental solution.

[0014] This invention was made in view of the above circumstances, and aims to provide a triangular pyramidal marker and a triangular pyramidal marker base that can achieve effects equivalent to or better than conventional conical markers by adopting a completely new triangular pyramidal shape for the external shape, without being bound by a conical shape, and that can solve various problems that have been a concern in the past all at once. [Means for solving the problem]

[0015] The assembly-type marker according to this invention, according to claim 1, comprises three side frame bodies having the same isosceles triangular shape, one base frame body having the shape of an equilateral triangle with sides corresponding to the base of each side frame body, a first connector that connects the adjacent hypotenuses of the three side frame bodies to each other, thereby maintaining a triangular pyramidal three-dimensional structure, and a second connector that connects the bases of the three side frame bodies to the three sides of the base frame body that are opposite to them, thereby more firmly maintaining the triangular pyramidal three-dimensional structure, and is characterized in that when assembled and used as a marker, the base frame body is installed to become the bottom surface.

[0016] Thus, by constructing the assembly-type marker device according to claim 1, wind and water will pass through the hollow space enclosed by the three side frames, thus providing the effect of remaining in the installation location without being affected by wind or water.

[0017] Furthermore, according to claim 2, the assembled marker according to this invention is characterized in that the first connector comprises a pair of first magnets attached to the adjacent slanted sides of the three side frame bodies, respectively, and connecting the slanted sides by magnetic attraction, and the second connector comprises a pair of second magnets attached to the bottom sides of the three side frame bodies and the corresponding sides of the bottom frame bodies, respectively, and connecting the sides by magnetic attraction.

[0018] By constructing the assembly-type marker according to claim 2 in this manner, the three isosceles triangular side frame bodies and the one equilateral triangular base frame body are connected by magnetic force, thereby maintaining a triangular pyramidal shape.

[0019] Furthermore, according to claim 3, the assembly-type marker according to this invention is characterized in that the first connector has the first magnets arranged in a manner corresponding to the vicinity of the top, central, and bottom of the slanted edge of the side frame body and the vicinity of the top, central, and bottom of the adjacent slanted edge of the side frame body, respectively.

[0020] By constructing the assembly-type marker according to claim 3 in this manner, the three side frame bodies that define the three hollow sides of the triangular pyramidal shape are connected to each other by magnetic force at three points on their oblique edges, thus ensuring that the triangular pyramidal shape is reliably maintained.

[0021] Furthermore, according to claim 4, the assembled marker according to this invention is characterized in that the first connector allows adjacent side frame bodies to separate by being pulled apart against the magnetic force of the first magnet.

[0022] By constructing the assembly-type marker device as described in claim 4, the triangular pyramidal shape is reliably maintained, while the three side frame bodies can be separated against magnetic force to disassemble the three-dimensional structure of the triangular pyramidal shape for movement or storage.

[0023] Also, according to the description of claim 5, the assembled sign tool according to the present invention is characterized in that the second coupling tool arranges the second magnet near one end, near the center, and near the other end of the bottom side of the side frame body, and near one end, near the center, and near the other end of the side of the bottom frame body adjacent thereto, respectively.

[0024] By configuring the assembled sign tool described in claim 5 in this way, the bottom frame body that defines one hollow bottom surface in the shape of a triangular pyramid will be magnetically connected to the bottom sides of the three side frame bodies at three locations on their respective sides, so the triangular pyramid shape will be surely maintained.

[0025] Also, according to the description of claim 6, the assembled sign tool according to the present invention is characterized in that the second coupling tool allows the bottom frame body and the side frame body to separate from each other by being pulled apart against the magnetic force of the second magnet.

[0026] By configuring the assembled sign tool described in claim 6 in this way, while the triangular pyramid shape is surely maintained in a state where the adsorption by the first and second magnets is maintained, for the purpose of moving and storing this, it becomes possible to separate the bottom frame body against the magnetic force with respect to the three side frame bodies, and thereby, the three-dimensional structure in the shape of a triangular pyramid can be disassembled.

[0027] Also, according to the description of claim 7, the assembled sign tool according to the present invention includes a pair of first snap coupling portions that are fitted together using elastic deformation on the adjacent hypotenuses of the three side frame bodies, and a first connecting portion that integrally connects both first snap coupling portions. The second coupling tool includes a pair of second snap coupling portions that are fitted together using elastic deformation on each bottom side of the three side frame bodies and each side of the corresponding bottom frame body, and a second connecting portion that integrally connects both second snap coupling portions.

[0028] By constructing the assembly-type marker according to claim 7 in this manner, the three isosceles triangular side frame bodies and the one equilateral triangular base frame body are joined by elastic interlocking, thereby maintaining a triangular pyramidal shape.

[0029] Furthermore, according to claim 8, the assembly-type sign device of this invention is characterized in that the first connector is positioned such that the first connecting portion corresponds to the vicinity of the top, central, and bottom of the slanted edge of the side frame body, and to the vicinity of the top, central, and bottom of the slanted edge of the adjacent side frame body, respectively.

[0030] By constructing the assembly-type marker according to claim 8 in this manner, the three side frame bodies that define the three hollow sides of the triangular pyramidal shape are connected to each other at three points by elastic interlocking at the snap portions, so that the triangular pyramidal shape is reliably maintained.

[0031] Furthermore, according to claim 9, the assembly-type marker according to this invention is characterized in that the first connector allows adjacent side frame bodies to separate by releasing the coupling against the elastic force of the first snap coupling.

[0032] By constructing the assembly-type marker according to claim 9 in this manner, the triangular pyramidal shape is maintained, while the three side frame bodies can be separated against the elastic force of the snap joints to disassemble the three-dimensional structure of the triangular pyramidal shape for movement or storage.

[0033] Furthermore, according to claim 10, the assembly-type sign device of this invention is characterized in that the second connector is positioned so as to correspond to the vicinity of one end, the central part, and the other end of the bottom edge of the side frame body, and the vicinity of one end, the central part, and the other end of the side of the bottom frame body adjacent thereto.

[0034] By constructing the assembly-type marker according to claim 10 in this manner, the three side frame bodies that define the three hollow sides of the triangular pyramidal shape and the one bottom frame body that defines the hollow bottom surface are connected to each other at three points by elastic snap-fitting at the snap portions, thus ensuring that the triangular pyramidal shape is maintained more reliably.

[0035] Furthermore, according to claim 11, the assembly type marker according to this invention is characterized in that the second connector allows the bottom frame and the side frame to separate from each other by releasing the coupling against the elastic force of the second snap coupling.

[0036] By configuring the assembly-type marker according to claim 11 in this way, the triangular pyramidal shape is reliably maintained while the elastic engagement of the snap joints is maintained, while the bottom frame can be separated from the three side frame bodies against the elastic engagement force of the snap joints for movement or storage, thereby allowing the three-dimensional structure of the triangular pyramidal shape to be disassembled. [Effects of the Invention]

[0037] According to this invention, by adopting a completely new triangular pyramidal shape for the external form, without being limited to a conical shape, it is possible to achieve effects equivalent to or better than conventional conical markers, and a triangular pyramidal marker base material is provided that can solve various problems that have been a concern in the past. [Brief explanation of the drawing]

[Figure 5] Figure 1 is a perspective view showing one modified example of the assembly-type marker device. [Figure 6] Figure 1 is a perspective view showing some of the components of another embodiment of the assembled signage device in a disassembled state. [Figure 7] Figure 6 is a plan view showing the configuration of a connector according to another embodiment used in the triangular pyramidal marker shown in Figure 6. [Modes for carrying out the invention]

[0039] The configuration of an assembled triangular pyramidal marker 10, which is one embodiment of the assembled marker according to the present invention, will be described below with reference to the attached drawings. [Examples]

[0040] First, as shown in Figures 1 to 4, the triangular pyramidal marker 10 of this embodiment consists of three first to third side frames 12, 14, and 16, each consisting of a frame that is an identical isosceles triangle, a single base frame 18 consisting of a frame that is an equilateral triangle with sides 18a, 18b, and 18c corresponding to the bases 12a, 14a, and 16a of each side frame 12, 14, and 16, and a first connector 20 that connects the three side frames 12, 14, and 16, and their adjacent hypotenuses 12b:16c, 12c:14b, and 14c:16b, thereby forming a triangular pyramidal solid. The device includes a first connector 20 that maintains the structure, and a second connector 22 that connects the bases 12a, 14a, 16a of the three side frame bodies 12, 14, 16 and the three sides 18c, 18a, 18b of the bottom frame body 18 that are opposite to each other. The second connector 22 connects the bases 12a, 14a, 16a of 12, 14, 16 and the three sides 18c, 18a, 18b of the bottom frame body 18, thereby more firmly maintaining the triangular pyramidal three-dimensional structure. When assembled and used as a marker, the bottom frame body 18 is positioned to become the base.

[0041] More specifically, Figure 3 shows the configuration of one embodiment of a base material for an assembly-type triangular pyramidal marker according to the present invention. This base material for the triangular pyramidal marker 10 is composed of three isosceles triangular side frames 12, 14, and 16 and one equilateral triangular base frame 18, and these three side frames 12, 14, and 16 and the base frame 18 are depicted arranged on a plane. Each of the side frames 12, 14, and 16 and the base frame 18 are formed by integrally combining rectangular cross-sectional frame materials in a triangular shape.

[0042] In this embodiment, the assembled triangular pyramidal marker 10 is constructed by overlapping the bases 14a, 16a, and 12a of the three side frames 14, 16, and 12 onto the three sides 18a, 18b, and 18c of the base frame 18, and then overlapping the adjacent hypotenuses 12b:16c, 12c:14b, and 14c:16b of the three side frames 12, 14, and 16 so that their vertices meet. In this embodiment, the vertices of the assembled triangular pyramidal marker 10 are exposed as shown in the figure.

[0043] On the other hand, the first connector 20 includes magnets a1, a2, a3 embedded in the top, middle, and bottom sides of one hypotenuse 12b of the first side frame 12, magnets b1, b2, b3 embedded in the top, middle, and bottom sides of the other hypotenuse 12c of the first side frame 12, and magnets c1, c2, c3 embedded in the top, middle, and bottom sides of one hypotenuse 14b of the second side frame 14. The device is constructed with magnets d1, d2, and d3 embedded in the top, middle, and bottom sides of the other hypotenuse 14c of the second side frame 14, magnets e1, e2, and e3 embedded in the top, middle, and bottom sides of one hypotenuse 16b of the third side frame 16, and magnets f1, f2, and f3 embedded in the top, middle, and bottom sides of the other hypotenuse 16c of the third side frame 16.

[0044] Then, in a state where the three isosceles triangular side frame bodies 12, 14, and 16 have hypotenuses 12b, 14b, and 16b of one side adjacent to the corresponding hypotenuses 16c, 12c, and 14c of the other side, forming a triangular pyramidal shape, the magnets attached to each hypotenuse are close to each other at the top, middle, and bottom, as shown in Figure 4, and attract each other by magnetic force. As a result, the adjacent hypotenuses 12b:16c, 12c:14b, and 14c:16b are integrated, and the triangular pyramidal structure is maintained.

[0045] On the other hand, the second connector 22, as again shown in Figure 3, includes magnets g1, g2, g3 embedded in one end, central part, and other end of the base 12a of the first side frame 12, magnets h1, h2, h3 embedded in one end, central part, and other end of the base 14a of the second side frame 14, magnets i1, i2, i3 embedded in one end, central part, and other end of the base 16a of the third side frame 16, and magnets embedded in one end, central part, and other end of the three bases 18a, 18b, and 18c of the base frame 18. TIFF2026084622000002.tif11166 is composed of these elements.

[0046] Then, when the bases 12a, 14a, and 16a of the three isosceles triangular side frame bodies 12, 14, and 16 are assembled so as to overlap with the three bases 18c, 18a, and 18b of the equilateral triangular base frame body 18 to form a triangular pyramidal shape, the magnets attached to each base are attracted to each other by magnetic force at one end, the central part, and the other end, as illustrated in Figure 4 as the case of the first connector 20. As a result, the bases 12a, 14a, and 16a of the three side frame bodies 12, 14, and 16 overlap with the three bases 18c, 18a, and 18b of the base frame 16, becoming integrated and the triangular pyramidal structure is firmly maintained.

[0047] Furthermore, Figure 4 illustrates a representative state in which a magnet a1 embedded in one hypotenuse 12b of the first side frame 12 and a magnet f1 embedded in the other hypotenuse 16c of the adjacent third side frame 16 are close to each other, and are attracted to each other by magnetic force, integrating the two sides. It goes without saying that the configuration of other opposing magnet pairs is also as shown in Figure 4.

[0048] As the triangular pyramidal marker 10 is constructed in the manner described above, it is clear from the fact that each component is made up of a frame, (1) Compared to conventional designs consisting of cone-shaped surfaces, the design is significantly lighter, making installation of the signage much easier and greatly improving work efficiency; (2) Compared to conventional designs consisting of a cone-shaped surface, the area subject to wind pressure is reduced to a minimum, for example, in strong winds. This allows the sign to be held stably in place without being blown away by wind pressure, and to fully perform its function as a marker.

[0049] On the other hand, as is clear from the fact that the base material for the triangular pyramidal marking device configured as described above comprises three isosceles triangular side frame bodies 12, 14, and 16 and one equilateral triangular bottom frame body 18, (A) Since each triangular shape can be stored separately from one another in a planar shape, it does not require a large storage space, and therefore storage costs will be lower. (B) Related to (A) above, when transporting the base material for the triangular pyramidal marker device from the storage location to the installation location using a truck or the like, the transport work becomes extremely easy because each triangular frame is lightweight, and when transporting multiple frames together, the number of frames can be appropriately selected according to the physical strength of each person, thus greatly improving work efficiency; (C) When transporting the base material for the triangular pyramidal marker from the storage location to the installation location (and similarly from the installation location to the storage location) using a truck or the like, it only requires stacking simple flat frame bodies, so it does not take up much space, and it becomes possible to load a larger number of units onto the truck or the like compared to conventional methods, thereby improving work efficiency due to the increased number of units that can be transported; (D) After transporting the base material to the installation location, it will be assembled into the triangular pyramidal marker 10 on site, but the assembly work is simply done by stacking three side frame bodies 1 By simply overlapping the adjacent hypotenuses of 2, 14, and 16 on the base frame 18, they are attracted to each other by magnetic force via the first connector 20 and become one. Similarly, by simply overlapping the bases 14a, 16a, and 18a of the three side frames 14, 16, and 12 with the three sides 18a, 18b, and 18c of the base frame 18, they are attracted to each other by magnetic force via the second connector 22 and become one, forming a strong triangular pyramidal shape, without impairing the workability of the installation of the triangular pyramidal marker 10.

[0050] It goes without saying that this invention is not limited to the configuration of the embodiment described above, and can be modified in various ways without departing from the spirit of the invention.

[0051] For example, in the description of the embodiment described above, the assembled sign was described as being constructed in which three isosceles triangular side frame bodies 12, 14, and 16 are arranged with their adjacent hypotenuses overlapping and their apexes aligned, exposing the vertex of a triangular pyramidal shape, as shown in Figure 1. However, this invention is not limited to such a configuration. For example, as shown in Figure 5 as a modified example, a small, hollow triangular pyramidal cover member 24, similar in shape to the triangular pyramidal sign 10, is firmly attached via a third connector to the vertex of the triangular pyramidal sign 10. This cover member covers the vertex and connects the vertices of the triangular pyramidal shape formed by the three side frame bodies 12, 14, and 16, and is colored, for example, yellow, to attract attention from the surroundings. In this modified example, the triangular pyramidal cover member 24 is not made of a frame, as the triangular pyramidal sign 10 is made of a thick, planar isosceles triangular plate material.

[0052] Furthermore, in the configuration of the embodiment described above, the base frame 18 was described as being composed of a hollow frame. However, in this modified example, as shown in Figure 5, a weight portion 26 is attached to the base frame 18 to prevent the assembled marker from being blown away by the wind or washed away by flowing water. In particular, in this modified example, the weight portion 26 is integrally attached to the base frame 18 in a removable manner. As described in the above embodiment, this triangular pyramidal marker 10 itself is hardly affected by wind and can maintain a self-supporting state when installed. However, if it is necessary to increase its own weight to prevent damage such as theft by a third party, the weight portion 26 will function effectively.

[0053] Here, the third connector, like the first and second connectors 20 and 22 described above, is designed to be attached via magnetic force. Although details are not shown, the cover member 24 is positioned on its inner surface, facing the magnets a1 and b1 embedded in the hypotenuses 12b and 12c of the first side frame 12, the magnets c1 and d1 embedded in the hypotenuses 14b and 14c of the second side frame 14, and the magnets e1 and f1 embedded in the hypotenuses 16b and 16c of the third side frame 16, with magnets attached to these magnets that are attracted to them via magnetic force.

[0054] Thus, in this modified form, the top of the triangular pyramidal marker 10 is covered by the cover member 24 and connected to each other, thereby further enhancing the marker function as a marker and providing the additional effect of maintaining the triangular pyramidal structure more firmly.

[0055] Furthermore, in the above-described embodiment, the first to third side frames 12, 14, 16 and the bottom frame 18 were described as being formed by integrally combining rectangular cross-sectional frame materials in a triangular shape. However, this invention is not limited to this configuration, and as shown in Figure 6 as another embodiment, the first to third side frames 12, 14, 16 and the bottom frame 18 may be formed by integrally combining circular cross-sectional frame materials in a triangular shape. In Figure 6, the adjacent hypotenuses 12b and 16c are depicted as representative parts of this other embodiment, and it goes without saying that the invention can also be applied to other combinations of hypotenuses and bases.

[0056] Furthermore, in the other embodiment, a magnetic coupling method was adopted for the first and second connectors 20 and 22. However, it goes without saying that the present invention is not limited to such a method, and as shown in Figures 6 and 7, the first and second connectors 28 and 30 can be used with mechanical frictional engagement force.

[0057] In detail, the first connecting member 28, as shown in Figure 7, comprises a pair of first snap connecting parts 28A and 28B that interlock the adjacent slanted edges of the three side frame bodies 12, 14, and 16 using elastic deformation, and a first connecting part 28C that integrally connects both first snap connecting parts 28A and 28B to each other, and is integrally molded from an elastic synthetic resin.

[0058] On the other hand, the second connector 30, as shown in Figure 7 when taken out together with the first connector member 28 described above, comprises a pair of second snap connectors 30A and 30B that fit together using elastic deformation to the bottom edges 12a, 14a, and 16a of the three side frame bodies 12, 14, and 16, and the corresponding sides 18c, 18a, and 18b of the bottom frame body 18, and a second connecting part 30C that integrally connects the two second snap connectors 30A and 30B to each other, and is integrally molded from an elastic synthetic resin.

[0059] Here, the first connector 28 is configured to interlock with the first connecting portion 28A, corresponding to the top, middle, and bottom areas of the hypotenuses 12b, 14b, and 16b of the side frames 12, 14, and 16, and the top, middle, and bottom areas of the hypotenuses 16c, 12c, and 14c of the adjacent side frames 16, 12, and 14, respectively. The first connector 28 is configured to connect adjacent hypotenuses 12b:16c, 12c:14b, and 14c:16b to each other by interlocking based on frictional engagement force. The first connector 28 is then released against the elastic holding force of the first snap connectors 28A and 28B, thereby allowing the hypotenuses 12b:16c, 12c:14b, and 14c:16b of adjacent side frames to separate.

[0060] On the other hand, the second connector 30 is configured such that the second connecting portion 30A is fitted into the vicinity of one end, the central part, and the other end of the base sides 12a, 14a, 16a of the side frames 12, 14, 16, and the vicinity of one part, the central part, and the other end of the sides 18c, 18a, 18b of the adjacent base frame 18, respectively, and connects the adjacent base sides 12a:18c, 14a:18a, and 1ta:18b to each other by fitting together based on frictional engagement force. Then, the second connector 30 is released against the elastic holding force of the second snap connectors 30A and 30B, thereby allowing the bottom frames 12a, 14a, and 16a of the adjacent side frames 12, 14, and 16, and the sides 18c, 18a, and 18b of the bottom frame 18 to separate from each other.

[0061] Furthermore, in the description of the above-mentioned embodiment, it was explained that the first connector 20 and the second connector 22 each have three magnets embedded on their corresponding sides. However, it goes without saying that this invention is not limited to such a number, and is not limited in any way to the number of magnets, as long as a sufficient magnetic bonding force can be obtained with two or even one magnet.

[0062] Furthermore, in the description of the above-mentioned embodiment, it was explained that the first connector 20 and the second connector 22 each have three magnets embedded on their corresponding sides. However, it goes without saying that this invention is not limited to this configuration, and magnets attached to the surface can also be used. [Industrial applicability]

[0063] As described in detail above, the triangular pyramidal assembly type signage device according to this invention is lightweight and well-ventilated, ensuring good retention at the installation location. Furthermore, the base material for the triangular pyramidal assembly type signage device consists of three isosceles triangular side frames and an equilateral triangular bottom frame that form the triangular pyramidal structure, which can be stored and transported in a completely separate state. This reduces the space required for storage and transport, and the weight during transport is reduced, greatly improving work efficiency. Its industrial applicability is immeasurable.
