  Hereinafter, the alerting tool 1 which concerns on embodiment of this invention is demonstrated in detail using drawing. FIG. 1 is a plan view of the alerting tool 1 of the present invention. It is assumed that the alerting tool 1 shown in FIG. 1 travels from the direction of arrow S and rides on the alerting tool 1. Further, the directions of “front-rear direction” and “width direction” described in the following description are directions viewed from the driver of the vehicle in FIG. In addition, the “vertical direction” is defined as an upward direction on the front side of the paper in FIG. 1 and a downward direction on the back side of the paper (direction laid on the road).

  As shown in FIG. 1, the alerting tool 1 includes ten annular members 2. These annular members 2 are formed in a substantially circular shape, and are arranged in such a manner that the outer peripheral side portions of the adjacent annular members 2 are adjacent to each other. More specifically, the annular member 2 is configured by arranging five rows in the width direction, two rows in the front-rear direction, and a substantially grid pattern in the front-rear direction and the width direction. The adjacent annular members 2 are connected to each other by connecting members 3 at the adjacent portions.

  In addition, the number of the annular members 2 of the alerting tool 1 is not limited to ten, and may be any number as long as it is arranged in a substantially grid pattern in the width direction and the front-rear direction. Absent. This number can be arbitrarily changed by adding or releasing the connection using the connecting member 3 described above. In addition, the number of rows and / or columns described above can be arbitrarily increased or decreased according to the width of the road to be laid.

FIG. 2 is an enlarged view of a portion A (annular member 2) of the alerting tool 1 of FIG. 3 is a cross-sectional view taken along line BB in FIG.
As shown in FIG. 2, the annular member 2 includes four concentric rings (specifically, a first concentric ring 2a from the inside, a second concentric ring 2b on the outside, and a third concentric ring on the outside. 2c, and a fourth concentric ring 2d) on the outer side (outermost side). The centers of the circles of the four concentric rings 2a to 2d are substantially coincident with each other, so that the annular member 2 is formed in a circular shape as a whole.

The annular member 2 is formed with a connecting member attaching portion 4 for attaching the connecting member 3 described above with an interval of about 90 degrees in the circumferential direction. As shown in FIG. 3, the connecting member mounting portion 4 extends in the normal direction of the ring and connects the first concentric ring 2a to the third concentric ring 2c (fourth concentric ring). Ring 2d is not connected, details of which will be described later).
Further, a connecting portion 5 is provided between the connecting member mounting portions 4 with an interval of about 30 degrees. This connection part 5 is extended in the normal line direction of a ring, and is formed in the aspect which connects all the 1st concentric rings 2a-the 4th concentric rings 2d.

The first concentric ring 2a to the fourth concentric ring 2d, the connecting member mounting portion 4, and the connecting portion 5 are integrally formed by resin molding. Thereby, the 1st concentric ring 2a-4th concentric ring 2d fulfill | performs the function which gives a vibration to the vehicle which passes on the alerting tool 1, and the connection member attaching part 4 and the connection part 5 are this annular member. The function for increasing the connection strength of 2 is achieved.
Further, the resin material of the annular member 2 is preferably a hard synthetic resin that has a small repulsive force when the vehicle rides while the vehicle is traveling, has a high contact force with the road surface, and is difficult to wear. That is, it is not preferable to use a soft material that can be bent and deformed by the annular member 2 itself.

As shown in FIG. 3, the connecting member attaching portion 4 includes a flat portion 6 having an upper surface formed flat and a gripping portion 7 for gripping the connecting member 3.
The flat portion 6 is formed so that the connecting member 3 can slide and move in the normal direction of the ring when the connecting member 3 is assembled or in the assembled state.

  The gripping part 7 is formed in a form protruding above the flat part 6, and a through hole 8 penetrating in the normal direction of the ring is formed in the gripping part 7. The gripping part 7 grips the connecting member 3 by inserting the connecting member 3 through the through hole 8. As shown in FIGS. 2 and 3, the gripping portion 7 includes a first gripping portion 7a formed on the upper side of the first concentric ring 2a to the second concentric ring 2c, and a fourth concentric ring 2d. And a second gripping portion 7b (a corresponding through hole 8 is also indicated by a first through hole 8a and a second through hole 8b).

4A and 4B show the connecting member 3 as a single product. FIG. 4A is a plan view, FIG. 4B is a side view, and FIG. 4C is a cross-sectional view taken along line CC in FIG. is there.
The connecting member 3 is formed in a flat plate shape having a longitudinal direction, and is formed of a resin material. As this resin material, a soft and flexible material is used. As will be described in detail later, when the annular members 2 connected adjacent to each other are folded, the connecting member 3 is freely bent or extended. It's like folding.

  Further, the connecting member 3 is formed so as to have a lower strength than the material of the annular member 2. For example, even when the alerting tool 1 is dragged by the vehicle, the annular member 2 is not broken, but the connecting member 3 is cut and broken.

The connecting member 3 is assembled so that the long direction is directed toward the adjacent annular members 2 in a state where the adjacent annular members 2 are connected.
The connecting member 3 is positioned on the first locking portion 11 positioned on the front end side 3a (the right end side in FIG. 4A) and on the opposite rear end side 3b (the left end side in FIG. 4A). The second locking portion 12 and the bent portion 13 that can be bent along a line substantially orthogonal to the longitudinal direction. As for this connection member 3, the front end side 3a is chamfered substantially circular so that it may be easy to insert in the through-holes 8a and 8b along a longitudinal direction.

As shown in FIGS. 4 (A) and 4 (B), the first locking portion 11 has a locking claw 11a protruding upward from its upper surface in the width direction (direction perpendicular to the longitudinal direction). Is formed.
On the other hand, a locking claw 12a is formed in the second locking portion 12 in the width direction in a manner protruding from the upper surface and the lower surface at the rear end portion.

  The bending portion 13 is formed so that it can be bent with a line orthogonal to the longitudinal direction as a fold line 40 (see FIGS. 6 and 8). Reinforcing ribs 13a and 13a are respectively formed at both ends of the bent portion 13 in the width direction. The ribs 13a and 13a are for preventing cracks and the like from occurring at both ends when the ribs are bent.

  The flat plate portion 13b located inside the bent portion 13 is formed to a thickness that allows the connecting member 3 to be bent easily. More specifically, in a state where the annular member 2 is connected by the connecting member 3, the adjacent annular members 2 are formed to a thickness that can be folded so that the operator can easily overlap (details). Will be described later).

  As shown in FIG. 3, the connecting member 3 is attached after the connecting member 3 is inserted from the front end side 3a into the through holes 8a and 8b of the annular member 2 located on the right side of the drawing, and then the annular member 2 on the left side of the drawing is attached. This is performed by inserting the through holes 8b and 8a. At this time, the locking claw 11a on the distal end side 3a of the connecting member 3 passes through the first gripping portion 7a of the left annular member 2 and is pushed in until it is locked to the edge of the first gripping portion 7a. The locking claw 12a on the rear end side 3b of the connecting member 3 is also locked to the edge of the first gripping portion 7a of the annular member 2 on the right side of the drawing. Thereby, the adjacent annular members 2 can be connected using the connecting member 3.

  When the locking claws 11a and 12a are in contact with the edge of the first gripping portion 7a (the state shown in FIG. 3), a gap L is formed between the adjacent annular members 2. . The length of the gap L is ensured to be easy to fold by overlapping the annular members 2. More preferably, the length is two times or more the thickness T of the annular member 2.

  Further, the connecting member 3 can freely slide and move on the flat portion 6. That is, if the annular members 2 are pushed in a direction in which they are close to each other in a connected state, the connecting member 3 slides on the flat portion 6 so that the gap L becomes small (the annular members 2 are in close contact with each other). Can also be adjusted).

  Next, the effect | action and folding method of the alerting tool 1 which concerns on embodiment of this invention are demonstrated using FIGS. 5 to 9, for ease of explanation, reference is made to the row (5 rows) of the annular member 2, and the first row 21, the second row 22, the third row 23, 4 columns 24 and 5 columns 25 are displayed.

  The alerting tool 1 can be folded compactly by alternately folding back the first row 21 to the fifth row 25. FIG. 5 shows a state in which the alerting tool 1 is in a state before it is folded and used on the road surface. From the state of FIG. 5, the first row 21 is lifted upward 30 as shown in FIG. 6. As a result, the connecting member 3 that connects the first row 21 and the second row 22 is in a mountain-folded state, while the connecting member 3 that connects the second row 22 and the third row 23 is valley-folded. It will be in the state.

  In this bending, the two connecting members 3 arranged in the front-rear direction are bent lines 40 (see FIGS. 6 and 8) extending in a direction substantially perpendicular to the longitudinal direction of the connecting member 3 (tangential direction of the ring of the annular member 2). ) And the two polygonal lines are on one straight line (the two straight lines coincide). For this reason, when the first row 21 and the second row 22 are to be bent, the two connecting members 3 are bent in the same direction along the same folding line 40, thereby facilitating the bending.

  By placing the first row 21 on the third row 23 from the state of FIG. 6, the first row 21 to the third row 23 are alternately folded and overlapped with the adjacent rows. become. At this time, since the gap L is secured at least twice the thickness T of the annular member 2, the gap L is overlapped until the upper and lower surfaces of the adjacent annular members 2 are completely in close contact with each other.

  In addition, the ease of bending is largely due to the flexibility of the connecting member 3. However, in the structure of this embodiment, the fourth concentric ring 2 d is additionally connected to the other first to third members by the connecting member mounting portion 4. Since the structure is not connected to the core rings 2a to 2c, the fourth concentric ring 2d in this portion is easily deformed, and the fourth concentric ring 2d is easily bent in the bending direction. Thereby, when folding, the adjacent annular members 2 are more easily bent.

  Similarly, as shown in FIG. 8, the superimposed first row 21 to third row 23 are lifted in the upward direction 31 and placed on the fifth row 25. As a result, as shown in FIG. 9, the first row 21 to the fifth row are overlapped and can be folded into a compact package during transportation or storage.

  According to the alerting tool 1 according to the embodiment of the present invention, a gap L is provided between the annular members 2 arranged adjacent to each other, and these annular members 2 are connected by a connecting member 3 that can be bent. Therefore, by bending the adjacent annular member 2 at the portion of the connecting member 3 and folding it, the packing form of the alerting tool 1 during transportation can be made compact. As a result, compared with the case where it does not fold, the conveyance work to the spot of the alerting tool 1 can be performed easily. In addition, it is not necessary to secure a large space for the transportation platform or a storage space for transportation, which is convenient.

  Further, since the gap L between the annular members 2 is formed to be twice or more the thickness of the annular member 2, the surfaces of the adjacent annular members 2 are matched and completely folded in two. By this, the package of the alerting tool 1 can be made more compact. As a result, it is possible to reduce the load of carrying work of the alerting tool 1.

  Furthermore, since the connecting member 3 is formed in a long shape toward the adjacent annular member 2 and is bent along the fold line 40 in a direction substantially perpendicular to the long direction, the connecting member is easily bent. It is possible to reduce the load of the operator's folding work.

  Furthermore, since the plurality of connecting members 3 are arranged so that the broken line 40 is the same line, the shape of the alerting tool 1 when it is in use (not folded) can be kept constant and folded. Sometimes the operator can easily perform the folding work.

  Further, since the plurality of annular members are arranged in a grid pattern, the bending operation of one of the plurality of connecting members does not become a resistance of the other bending operation, and the folding work of the alerting tool 1 is facilitated. You can do it. Moreover, the alerting tool 1 can be packed compactly in the folded state.

  On the other hand, according to the folding method of the attention-raising tool 1 according to the embodiment of the present invention, since the plurality of annular members 2 are alternately folded in an overlapping manner, the attention-raising tool 1 at the time of transportation is compactly collected. Can do. Moreover, since the operation | work which folds the alerting tool 1 can be performed easily as if a futon is folded, the burden of an operator's laying operation | work can be reduced.

As mentioned above, although the alerting tool according to the embodiment of the present invention has been described, the present invention is not limited to the above-described embodiment, and various modifications and changes can be made based on the technical idea of the present invention. is there.
For example, in the present embodiment, the shape of the annular member 2 is circular, but the shape is not limited to a circle as long as it can be easily folded. Further, although the annular member 2 is arranged in a grid pattern, the arrangement is not limited to this arrangement as long as it can be easily folded.

  For example, the alerting tool 50 shown in FIG. 10A is formed by arranging approximately hexagonal annular members 52 in a substantially staggered manner and connecting them using the connecting member 3. Even in this case, the annular members 52 are alternately folded by providing a gap of at least twice the thickness of the annular members 52 between the adjacent annular members 52, as shown in FIG. It can be made into a compact packaging. Further, in such a structure, the fold line of the connecting member 3 can be made substantially orthogonal to the longitudinal direction of the connecting member 3 and can be made parallel to the hexagonal side, so that the structure can be easily bent. can do.

  Moreover, the alerting tool 60 shown to FIG. 11 (A) is connected using the connection member 3 by arranging the substantially triangular annular member 62 in a line with the top and bottom being alternately reversed. Even in this case, the annular members 62 are alternately folded by providing a gap of at least twice the thickness of the annular members 62 between the adjacent annular members 62, as shown in FIG. It can be made into a compact packaging. Further, in such a structure, the fold line at the time of bending of the connecting member 3 can be made substantially perpendicular to the longitudinal direction of the connecting member 3 and can be made parallel to the side of the triangle. It can be configured to be easily bent.

  On the other hand, as shown in FIG. 12 (conventional view), even when the annular members 102 are arranged in a staggered manner, it is possible to provide a sufficient gap between adjacent annular members 102 and It can fold by connecting with the connecting member 3 which has flexibility. However, since the connecting point of the two annular members 102 to be connected exists at an angle of about 120 degrees with the center of the annular member 102 as the base point, the fold line when the connecting member 3 is bent is connected to the longitudinal direction of the connecting member 3. It cannot be made to be substantially orthogonal to the direction, and these broken lines cannot be on the same straight line. Therefore, the connecting member 3 is bent obliquely for bending. Therefore, the arrangement of the annular member 102 for folding the alerting tool is not preferable.

  In addition, the connecting member 3 in the present embodiment is formed of an integrally molded flexible resin material. For example, the connecting member 3 can be bent or extended structurally like a caterpillar. It does not matter. That is, when the adjacent annular members 2 are folded, the connecting member can follow the bending and can be used for the present invention as long as it can be folded easily.

  Further, in the present embodiment, flexible members are used for all the connecting members 3, but the flexible connecting members 3 are used only in places necessary for folding, and the connecting members 3 are not folded. A highly rigid connecting member can also be used for the portion. For example, even if the annular members 2 arranged adjacent to each other in the front-rear direction in FIG. 1 are connected using a highly rigid connecting member, they can be combined into the folded shape shown in FIG. Accordingly, it is possible to provide a high-rigidity warning device that is more suitable for use in consideration of the folding shape and the load direction in which the vehicle rides on the warning device.

  Furthermore, in the present embodiment, the folding line 40 for folding is configured to be substantially the same line as the tangent line of the adjacent annular member 2 (the folding line 40 and the tangent line substantially overlap). The position of the broken line 40 can also be shifted. FIG. 12 is a plan view showing a state in which the annular member 2 is divided and connected by the connecting member 3 according to another embodiment of the present invention.

  The alerting tool 70 shown in FIG. 12 includes semicircular members 73 and 73 obtained by dividing an annular member 72 into a semicircular shape, a gap is formed in the divided portion, and the divided portion has elasticity. It is connected by a connecting member 3 that can be bent. Since the connection structure using this connection member 3 is the same structure as this Embodiment, it abbreviate | omits about the detailed description. Adjacent annular members 72 are firmly connected by a rigid and non-bending connecting member 74. The connecting member 74 may be formed integrally with the semicircular member 73.

  In such a configuration, the fold line 40 for folding the alerting tool 70 is the same line as the line connecting the two connecting members 3. By folding alternately on the basis of the broken line 40, the alerting tool 70 can be easily folded and can be compactly assembled. Furthermore, since the two connecting members 3 exist on the broken line 40, the connection strength can be further improved.

  In addition, it can connect with the connection member 3 which has elasticity instead of the connection member 74, and it can also be made to be able to be folded also in this part. If comprised in this way, folding shape can be made further compact.
