Description

[Technical Field]

[0001] The present invention relates to a folding sign. [Background technology]

[0002] Cone markers, which are integrally molded from colored plastic such as red, are commonly used as traffic control signs lined up at traffic accident investigation sites and traffic control checkpoints, and as division markers lined up at construction sites such as road construction, power line installation, and building construction. These common cone markers have a square base with a cone-shaped main body protruding from it.

[0003] Such cone signs, which are integrally molded from plastic, have the disadvantage of being inconvenient to transport and store. In view of this situation, a foldable cone sign that folds into a flat state for easy transport and storage is known (see Patent Document 1 below). [Prior art documents] [Patent documents]

[0016] <Embodiment> Hereinafter, an embodiment of a folding sign according to the present invention will be described with reference to the drawings. Note that the embodiment shown below is an example of the present invention, and the present invention is not limited to the following embodiment, and various configurations can be adopted.

[0017] Here, Fig. 1 is an overall perspective view of a folding sign 1 according to an embodiment in an assembled state. Fig. 2 is a diagram showing the folding sign 1 according to an embodiment in an unfolded state. Fig. 3 is a diagram illustrating the mechanism of a cord hinge 11 of the folding sign 1. Fig. 4 is a diagram illustrating the mechanism of a cord hinge 13 of the folding sign 1. Fig. 5 is a diagram showing the folding sign 1 in a folded state. Fig. 6 is a diagram showing an example in which the folding sign 1 in a folded state is fixed with a fixing cord.

[0018] In the following description, the terms "upward" and "downward" correspond to the upward and downward directions in the foldable sign 1 shown in Figures 1 and 2. That is, when the foldable sign 1 is viewed from the front in an unfolded state, the side of the first member 3 of the foldable sign 1 is referred to as the "left" and the side of the third member 7 is referred to as the "right." Additionally, the bottom side of the foldable sign 1 is referred to as the "down" and the side opposite the bottom is referred to as the "up."

[0019] The folding sign 1 is formed by connecting a flat, substantially trapezoidal first member (first surface) 3, a second member (second surface) 5, and a third member (third surface) 7. The first member 3 and the second member 5 are connected by a pair of first hinges 11, 11', and the second member 5 and the third member 7 are connected by a pair of second hinges 13, 13'. That is, the pair of first hinges 11, 11' connect the first member 3 and the second member 5 and support the two members 3, 5 so that they can rotate relatively 360 degrees around this connection, and the pair of second hinges 13, 13' connect the second member 5 and the third member 7 and support the two members 5, 7 so that they can rotate relatively 360 degrees around this connection. It is preferable to use cord hinges as the pair of first hinges 11, 11' and the pair of second hinges 13, 13', and hereinafter these may be referred to as the first cord hinge 11 and the second cord hinge 13. A cord hinge is a type of hinge that connects adjacent objects to be connected with a long, thin cord, and allows the objects to rotate 360 ​​degrees around the connection point.

[0020] If one surface of the first member 3, second member 5, and third member 7, which are connected in the unfolded state (see Figure 2), is designated as the first surface and the other surface as the second surface, then, for example, the first member 3 and third member 7 can be rotated 360 degrees around the second member 5 by the first string hinge 11 and the second string hinge 13. As a result, the folding sign device 1 can be assembled into a usage form of a roughly triangular pyramid, with either the first or second surface serving as the first sign surface (front surface) and the other surface serving as the second sign surface (back surface). Therefore, the folding sign device 1 can use both the first sign surface and the second sign surface as display areas.

[0021] In addition, when the folding sign 1 is assembled as shown in Figure 1, the first member 3, second member 5, and third member 7 form a roughly triangular pyramid shape, and the assembled state can be maintained by binding each member with an elastic fixing string 15. In addition, the adjacent end faces of the first member 3, second member 5, and third member 7 are chamfered at an angle of approximately 60 degrees. As each chamfer is in surface contact in the assembled state, no gaps are formed at the connecting parts, increasing the rigidity of the entire folding sign 1.

[0022] (Structure of string hinges 11, 11', 13, 13') The structure of the string hinges 11, 11', 13, and 13' will be described below with reference to FIG. The first member 3 has a plurality of third first string holes 17' drilled at a predetermined pitch along the height direction near the lower side of the connecting edge between the first member 3 and the second member 5 for inserting the third string 21', and the second member 5 has a plurality of second first string holes 18 drilled at a predetermined pitch along the height direction near the upper side of the connecting edge between the first member 3 and the second member 5 for inserting the first string 21. The second member 5 is provided with a plurality of fourth first cord passage holes 18' at a predetermined pitch along the height direction near the lower side of the connecting side between the first member 3 and the second member 5, for passing the third cord 21' through. The second member 5 is provided with a plurality of first second cord passage holes 19 at a predetermined pitch along the height direction near the upper side of the connecting side between the second member 5 and the third member 7, for passing the second cord 22 through. The second member 5 is provided with a plurality of third second cord passage holes 19' at a predetermined pitch along the height direction near the lower side of the connecting side between the second member 5 and the third member 7, for passing the fourth cord 22' through. The third member 7 is provided with a plurality of second second cord passage holes 20 at a predetermined pitch along the height direction near the upper side of the connecting side between the second member 5 and the third member 7, for passing the second cord 22 through. The third member 7 has a plurality of fourth second string insertion holes 20' formed at a predetermined pitch along the height direction near the lower side of the connecting side between the second member 5 and the third member 7 for inserting a fourth string 22' therethrough. A pair of first hinges 11, 11' is formed by alternately inserting a first string 21 through the first first string hole 17 and the second first string hole 18 and stretching it across the first member 3 and the second member 5, and by alternately inserting a third string 21' through the third first string hole 17' and the fourth first string hole 18' and stretching it across the first member 3 and the second member 5. The second string 22 is alternately inserted through the first second string hole 19 and the second second string hole 20 and stretched across the second member 5 and the third member 7, and the third string 21' is alternately inserted through the third second string hole 19' and the fourth second string hole 20' and stretched across the second member 5 and the third member 7, thereby forming a pair of second hinges 13, 13'. The predetermined pitch of the string holes 17, 17', 18, 18', 19, 19', 20, 20' formed in the first member 3, the second member 5 and the third member 7 is preferably equal to the thickness of the strings 21, 21', 22, 22'.

[0023] (Structure and materials of the first member 3, the second member 5, and the third member 7) The structures and materials (raw materials) of the first member 3, second member 5, and third member 7 are described below with reference to FIG. 2. The first member 3, second member 5, and third member 7 are made of wood, with natural wood being preferred in terms of appearance and durability. The first member 3 is formed by joining (connecting) a first member main body 3a, an upper divided member 3b connected (joined) to the upper side of the first member main body 3a, and a lower divided member 3c connected (joined) to the lower side of the first member main body 3a. The second member 5 is formed by joining (connecting) a second member main body 5a, an upper divided member 5b connected (joined) to the upper side of the second member main body 5a, and a lower divided member 5c connected (joined) to the lower side of the second member main body 5a. The third member 7 is formed by connecting (joining) a third member main body 7a, an upper divided member 7b connected (joined) to the upper side of the third member main body 7a, and a lower divided member 5c connected (joined) to the lower side of the third member main body 7a.

[0024] A preferred joining (bonding) method is, for example, a tongue-and-groove joint, in which a groove called a "tongue" is cut approximately in the center of the thickness direction of both parts to be joined, and a tongue and groove matching the width and depth of the groove is inserted (sandwiched) between them to fill the gap between the two parts. This type of bonding allows for a large bonding area and strong adhesion. The bonding method is not limited to this, and examples include drilling holes in both materials to be joined, the upper and lower bonding surfaces of the main body of the parts, and the lower and upper bonding surfaces of the upper divided member, and then inserting a "dowel" coated with adhesive into the hole to form the bond. Alternatively, a strong adhesive may be applied directly to the connecting surfaces to form the bond.

[0025] For the first member 3, wood is used in which the grain direction of the first member main body 3a is different from that of the upper divided member 3b, and wood is used in which the grain direction of the first member main body 3a is different from that of the lower divided member 3c. For the second member 5, wood is used in which the grain direction of the second member main body 5a is different from that of the upper divided member 5b, and wood is used in which the grain direction of the second member main body 5a is different from that of the lower divided member 5c. For the third member 7, wood is used in which the grain direction of the third member main body 7a is different from that of the upper divided member 7b, and wood is used in which the grain direction of the third member main body 7a is different from that of the lower divided member 7c. It is preferable that the grain direction of each main body is vertical (longitudinal), and that the grain direction of each upper divided member and lower divided member is horizontal (longitudinal), and it is desirable that the grain direction of the main body and the grain direction of the upper divided member and lower divided member are perpendicular to each other.

[0026] The grain of natural wood refers to the annual rings and other patterns that appear on the cross section of a sawn tree. Known varieties include "cross grain" and "straight grain." Wood shrinks, and the rate of shrinkage, or shrinkage rate, varies depending on the direction. It is generally known that when each of the components 3, 5, and 7 is made from a single piece of wood, warping occurs based on the shrinkage rate corresponding to the grain direction. Therefore, by connecting the grain direction of the main body 3a, 5a, and 7a of the component to the upper divided members 3b, 5b, and 7b and the lower divided members 3c, 5c, and 7c so that the grain direction of the main body 3a, 5a, and 7a is different from that of the upper divided members 3b, 5b, and 7b and the lower divided members 3c, 5c, and 7c, the warping of the main body 3a, 5a, and 7a of the component is suppressed by the upper divided members 3b, 5b, and 7b and the lower divided members 3c, 5c, and 7c. At the same time, the warping of the upper divided members 3b, 5b, and 7b and the lower divided members 3c, 5c, and 7c of the component is suppressed by the main body 3a, 5a, and 7a of the component. Depending on the purpose and environment of use of the folding sign 1 of the present invention, materials such as solid wood, laminated wood, plywood, etc. can be selected appropriately for the first member 3, second member 5, and third member 7. Furthermore, the materials and colors of each main body and each upper and lower divided member may be different.

[0027] (Fixing structure of each member 3, 5, 7 after folding using fixing string 15) The structure for fixing the members 3, 5, and 7 with the fixing string 15 after folding will be described below with reference to Fig. 3. As shown in Fig. 3, two fixing string holes 16, 16 are formed in the vicinity of the top of the first member 3 at a predetermined distance from each other in the width direction. When the first member 3, the second member 5, and the third member 7 are in a folded state (see Fig. 5), an elastic fixing string 15 for looping around the first member 3, the second member 5, and the third member 7 is attached via the fixing string holes 16, 16.

[0028] Regarding the method of using the fixing string 15, when the first member 3, the second member 5, and the third member 7 are in a folded state (see FIG. 5), the fixing string 15 is pulled and looped around the upper vicinity of the first member 3, the second member 5, and the third member 7, thereby maintaining the stacked state of the first member 3, the second member 5, and the third member 7 as shown in FIG. 6. Note that, although the example described above is an example in which the fixing string 15 is attached to the first member 3, the fixing string 14 may also be attached to the second member 5 or the third member 7.

[0029] (Method of fixing the sign 1 after assembly using the fixing string 15) A method for fixing the assembled foldable sign 1 with the fixing cord 15 will be described below with reference to Fig. 1. The fixing structure using the fixing cord 15 has been described above, so a detailed description will be omitted. As shown in Fig. 1, when the foldable sign 1 is in the sign use state (assembled state), the fixing cord 15 is pulled and looped around the upper vicinity of the first member 3, the second member 5, and the third member 7, thereby maintaining the foldable sign 1 in the sign use state as shown in Fig. 1. Although the above example is an example in which the fixing cord 15 is attached to the first member 3, the fixing cord 14 may also be attached to the second member 5 or the third member 7.

[0030] (effect) (1) The folding sign device 1 according to the embodiment is formed by connecting a first member 3, a second member 5, and a third member 7, which are flat and have an approximately trapezoidal shape. The first member 3 and the second member 5 are connected by a first string hinge 11, and the second member 5 and the third member 7 are connected by a second string hinge 22. When the sign device is unfolded, one side of the first member 3, the second member 5, and the third member 7, which are connected together, is the first side, and the other side is the second side. The sign device is assembled into a usable form in which either the first side or the second side is the first sign side, and the other side is the second sign side. Therefore, the marker can be used reversibly, which improves the degree of freedom in how the marker can be used. (2) In addition, in the folding sign device 1 according to the embodiment, the first hinge 11 and the second hinge 13 are made of string hinges, and the first hinge 11 connects the first member 3 and the second member 5 and supports the first member 3 and the second member 5 so that they can rotate 360 ​​degrees relative to each other around the connection point, and the second hinge 13 connects the second member 5 and the third member 7 and supports the second member 5 and the third member 7 so that they can rotate 360 ​​degrees relative to each other around the connection point. Therefore, string hinges have more clearance in the up, down, left and right directions than regular hinges that are fixed with screws, which allows for smoother folding and assembly operations. (3) The first hinge is composed of a pair of hinges 11, 11', one hinge is provided on the upper side of the first member 3 and the second member 5, and the other hinge is provided on the lower side of the first member 3 and the second member 5; the second hinge is composed of a pair of hinges 13, 13', one hinge is provided on the upper side of the second member 5 and the third member 7, and the other hinge is provided on the lower side of the second member 5 and the third member 7. Therefore, folding and assembly operations can be performed more smoothly. (4) Furthermore, according to the folding sign 1 of the embodiment, the first member 3 has a plurality of first first cord-passing holes 17 formed at a predetermined pitch along the height direction in the vicinity of the upper side of the connecting side between the first member 3 and the second member 5, through which the first cord 21 is passed. The first member 3 has a plurality of third first cord-passing holes 17' formed at a predetermined pitch along the height direction in the vicinity of the lower side of the connecting side between the first member 3 and the second member 5, through which the third cord 21' is passed. The second member 5 has a plurality of second first cord-passing holes 18 formed at a predetermined pitch along the height direction in the vicinity of the upper side of the connecting side between the first member 3 and the second member 5, through which the first cord 21 is passed. The second member 5 is provided with a plurality of fourth first cord passage holes 18' at a predetermined pitch along the height direction near the lower side of the connecting side between the first member 3 and the second member 5, for passing the third cord 21' through. The second member 5 is provided with a plurality of first second cord passage holes 19 at a predetermined pitch along the height direction near the upper side of the connecting side between the second member 5 and the third member 7, for passing the second cord 22 through. The second member 5 is provided with a plurality of third second cord passage holes 19' at a predetermined pitch along the height direction near the lower side of the connecting side between the second member 5 and the third member 7, for passing the fourth cord 22' through. The third member 7 is provided with a plurality of second second cord passage holes 20 at a predetermined pitch along the height direction near the upper side of the connecting side between the second member 5 and the third member 7, for passing the second cord 22 through. The third member 7 has a plurality of fourth second string insertion holes 20' formed at a predetermined pitch along the height direction near the lower side of the connecting side between the second member 5 and the third member 7 for inserting a fourth string 22' therethrough. The pair of first hinges 11, 11' are formed by alternately inserting a first string 21 through the first first string hole 17 and the second first string hole 18 and stretching it across the first member 3 and the second member 5, and by alternately inserting a third string 21' through the third first string hole 17' and the fourth first string hole 18' and stretching it across the first member and the second member 5. The second string 22 is alternately inserted through the first second string hole 19 and the second second string hole 20 and stretched across the second member 5 and the third member 7, and the third string 21' is alternately inserted through the third second string hole 19' and the fourth second string hole 20' and stretched across the second member 5 and the third member 7, thereby forming the pair of second hinges 13, 13'. Therefore, the folding sign device 1 can be rotated 360 degrees, allowing for a variety of sign usage modes. (5) Furthermore, according to the folding sign device 1 of the embodiment, the first member 3, the second member 5, and the third member 7 are made of wood, and each of the first member 3, the second member 5, and the third member 7 is formed by connecting a member main body 3a, 5a, 7a, an upper divided member 3b, 5b, 7b connected to the upper side of the member main body 3a, 5a, 7a, and a lower divided member 3c, 5c, 7c connected to the lower side of the member main body 3a, 5a, 7a. For the member main bodies 3a, 5a, 7a, the upper divided members 3b, 5b, 7b, and the lower divided members 3c, 5c, 7c, wood is used in which the grain direction of the member main bodies 3a, 5a, 7a and the upper divided members 3b, 5b, 7b differs, and wood is used in which the grain direction of the member main bodies 3a, 5a, 7a and the lower divided members 3c, 5c, 7c differs. In recent years, there has been an accelerating trend toward a carbon-free, plastic-free society that uses as few plastic materials as possible, and the folding sign 1 described above is environmentally friendly because it is made entirely of wood except for the string hinges 11 and 13. Furthermore, the grain direction of the main body of the member 3a, 5a, 7a is different from that of the upper divided members 3b, 5b, 7b and the lower divided members 3c, 5c, 7c, which helps prevent warping of the members 3, 5, 7. (6) Fixing string holes 16, 16 are drilled at a predetermined interval from each other in the width direction near the top of any of the first member 3, the second member 5 and the third member 7 (in this embodiment, the first member 3), and when the sign is assembled in its usage form, an elastic fixing string 15 for hanging around the first member 3, the second member 5 and the third member 7 is attached via the fixing string holes 16, 16. Therefore, since the fixing string 15 is hooked (tied) on the first member 3, the second member 5 and the third member 7 in a state where they are assembled in the sign usage form, the state where they are assembled in the sign usage form can be maintained. (7) Furthermore, according to the folding sign device 1 of the embodiment, fastening string holes 16, 16 are drilled at predetermined intervals in the width direction near the top of any one of the first member 3, the second member 5, and the third member 7 (the first member 3 in the embodiment), and when the first member 3, the second member 5, and the third member 7 are folded, an elastic fastening string 15 for hanging around the first member 3, the second member 5, and the third member 7 is attached via at least two of the fastening string holes 16, 16. Therefore, since the fixing string 15 is hooked (tied) around the first member 3, the second member 5 and the third member 7 in a folded state, the folded state can be maintained.

[0031] <Modification> Below, a modified example of the folding sign according to the present invention will be described with reference to Figures 7 and 8. The modified example is the same except that it further includes a first protrusion 31 and a second protrusion 33, so only the different parts will be described and a description of similar parts will be omitted. Furthermore, the same reference numerals may be used for similar parts when there is no need to distinguish between them.

[0032] In the unfolded state, if the left-hand member in the unfolded state is the first member 3, the right-hand member is the third member 7, and the central member placed between the first member 3 and the third member 7 is the second member 5, a first protrusion 31 is erected near the center of the side surface 43 of the first member 3 (at a position approximately halfway up the height from the bottom surface to the top surface), and second protrusions 33, 33 are erected at a predetermined interval near the center of the side surface 47 of the third member 7 at a position where the first protrusion 31 can be clamped in the assembled state (see Figure 7). Therefore, according to the folding sign device of the modified example, as shown in Figure 8, the first protrusion is sandwiched between the two second protrusions when assembled, which prevents the sign device from shaking up and down when placed on the ground after assembly or when carrying the sign device.

[0033] The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present invention. (1) For example, the material of the folding sign in the embodiment is wood, but it may also be a highly rigid material, such as a plastic material such as polyethylene terephthalate, acrylic resin, or polystyrene, or corrugated cardboard (heavy paper), etc. If it is made of a material other than wood, there is no wood grain, so the main body, upper divided member, and lower divided member may be molded integrally without being connected. (2) The attachment positions of the cord hinges are not limited to those described in the embodiments, as long as they are positions that allow easy rotation of the members 3, 5, and 7. Furthermore, although the embodiment shows an example in which there are two cord hinges between the members, for a total of four cord hinges, there may be three to five or more cord hinges between the members, for a total of six to ten or more cord hinges. (3) In the above embodiment, an example was shown in which string hinges were used as the first hinge and the second hinge, but instead of string hinges, flag hinges that can rotate 360 ​​degrees around an axis may also be used. (4) If the folding sign is made of wood, it may be coated with oil such as linseed oil to enhance durability, waterproofness, and stain resistance. In addition to oil coating, lacquer coating, which is applied by dissolving resin in a highly volatile solvent (alcohol or thinner), or urethane coating, which is applied using urethane resin, may also be used.
