Description

  The present invention relates to a connection member of a warning tool used for a warning tool that is temporarily laid on a road and for connecting adjacent annular members.

  Conventionally, at work sites such as road construction, warning tools have been laid on the road in order to prevent ordinary vehicles from entering the work site. As this alerting tool, there is, for example, one in which a plurality of annular members formed in an annular shape are arranged in a plane, and the vehicle that runs (rides) on the alerting tool is alerted by vibration. Moreover, the connection member for connecting adjacent annular members along a road surface is used for this alerting tool. (For example, refer to Patent Document 1).

  As shown in FIG. 11, the conventional connecting member 200 includes an insertion member 210 and a locking member 220. The insertion member 210 is formed in a long band shape from the base end portion 210A to the tip end portion 210B, and a protrusion hole 211 into which the protrusion 221 of the locking member 220 is fitted to the tip end portion 210B. And the engagement square hole 212 which the latching claw 222 of the latching member 220 engages is formed. In addition, a connecting member insertion hole through which the insertion member 210 is inserted is formed in an annular member (not shown) connected adjacently.

  The insertion member 210 is inserted from one connecting member insertion hole of the adjacent annular member, and is inserted until the tip portion 210B projects outside the connection member insertion hole of the other annular member. And two annular members are connected by attaching the locking member 220 to the front-end | tip part 210B which protrudes. Since the locking member 220 is attached by aligning the positions of the protrusion 221 and the locking claw 222 and pushing from the upper side of the annular member, the operator can easily attach (or remove) from the upper side. Excellent in terms.

  However, since the locking member 220 of the connecting member 200 described above is locked in the vertical direction (vertical direction, locking direction) with respect to the road surface from the upper side of the annular member, the vehicle traveling on the alerting tool. This coincides with the load direction received by the annular member. Therefore, when the annular member repeatedly receives a load from the vehicle, the locking member 220 also receives the load repeatedly in the locking direction. Therefore, there is a possibility that the locking member 220 repeatedly slides in the locking direction and easily falls off the insertion member 210 due to wear or the like.

  Further, in the conventional locking member 220, the protrusion 221 protruding downward (in the direction of the road surface) is fitted into the protrusion hole 211 from above, so that the locking member 220 is locked. The lower end of the protrusion 221 protrudes below the insertion member 210. Therefore, the protrusion 221 may be repeatedly contacted with the road surface and worn by the load received from the vehicle. When the protrusion 221 is worn, the fitting between the protrusion 221 and the protrusion hole 211 is likely to be released.

  The present invention has been made in view of the above-described circumstances, and the purpose thereof is to provide a connection member for a warning tool that prevents the locking member from falling off even when a load is repeatedly applied from a vehicle traveling on the warning tool. It is for providing.

In order to solve the above-described problems, the present invention relates to a manner in which the outer peripheral ends of a plurality of annular members are connected in an adjacent manner, and a driver of a vehicle laying on a road and passing through the road is alerted by vibration. Connection of a warning tool that is used in a stimulating tool and includes an insertion member that is inserted from one of the outer peripheral edge portions of the adjacent annular members toward the other, and a locking member that locks the insertion member The locking member is locked to the insertion member from a direction different from a load direction received by a vehicle traveling on the annular member, and protrudes in the load direction from the insertion member. A first locking portion is formed, and the locking member is separated by slits formed on both sides in the width direction, and the first locking portion is separated by the slit and receives the load of the vehicle. setting an elastic portion to flex the loading direction towards the Is, the elastic portion protrudes in the loading direction, wherein the second locking portion is deeper engagement between said first engaging portion by the elastic portion bends are formed .

  The locking member may be locked to the insertion member from a direction along the road surface of the road.

Further, the engaging plate member that covers an upper provided a member, that the to attach the plate-like member together with the annular member when connecting the outer peripheral end portion of the annular member adjacent to the annular member You can also.

Furthermore, the insertion member may be flexible, and the insertion member may be bent so that one of the adjacent annular members overlaps the other.

In the connecting member of the alerting tool according to the present invention, the locking member is locked to the insertion member from a direction different from the load direction received by the vehicle traveling on the annular member. Compared with the case where the stopping direction matches, the locking member is less likely to move in the locking direction due to the load received from the vehicle. Therefore, it becomes difficult for the locking member to fall off the insertion member due to wear or the like. Moreover, since the protrusion part which protrudes below is not provided unlike the past, it becomes difficult for a locking member to drop | omit from an insertion member by abrasion etc.
Further, the insertion member is formed with a first locking portion that protrudes in the load direction, and the locking member is separated by slits formed on both sides in the width direction and the slit, When receiving a load, an elastic portion that is bent in the load direction toward the first locking portion is provided, and the elastic portion protrudes in the load direction, and the elastic portion is bent to Since the 2nd latching | locking part which meshes | engages with a 1st latching | locking part becomes deep, it comes to mesh | engage more strongly with respect to the load of a vehicle, and a latching member becomes difficult to drop | omit from an insertion member.

  Hereinafter, the connection member of the alerting tool which concerns on embodiment of this invention is demonstrated in detail using drawing. FIG. 1 is a plan view of the alerting tool 60, and FIG. 2 is a perspective view of FIG. 3 is a perspective view showing a state in which the plate-like member 70 is attached to the single annular member 61, and FIG. 4 is a plan view showing the annular member 61 alone.

  The directions used in the following description are the upper side in FIG. 1 as the upward direction, the depth direction in the paper direction as the downward direction, and the vertical direction in the paper direction as the left and right direction (width direction). Moreover, the arrow S shown in FIG. 1 has shown the approach direction of the vehicle.

  As shown in FIG. 1 and FIG. 2, the alerting tool 60 has four annular members 61 arranged in a straight line, and is arranged over the entire length of the road to be laid. Although the number of the annular members 61 of the alerting tool 60 is four in this embodiment, it can be appropriately changed to five or more or three or less according to the road width. Thereby, it can be made to ride on this alerting tool 60 no matter which part of the road width the traveling vehicle passes, and the driver can be alerted with certainty.

Further, the four annular members 61 shown in FIGS. 1 and 2 are configured in one row along the vehicle traveling direction S, but may be configured in two rows or more. Thereby, alerting can be performed more reliably by giving more vibration to the driver.
Increasing or decreasing the number of the annular members 61 can be easily performed by releasing or releasing connection or connection of connecting members R (insertion member 90 and locking member 95), which will be described in detail later.

  As shown in FIGS. 1 to 3, plate members 70 are attached to the four annular members 61, respectively. The plate-like member 70 is used for various purposes by being attached to the alerting tool 60. For example, it is possible to notify the driver of the vehicle of a visual mark by painting a caution color or a light emission color on each of the plate-like members 70 arranged in a straight line in a row. As this mark, for example, the driver can be visually alerted and decelerated, or can have a function of notifying a guideline (stop line) for stopping the vehicle in a one-way alternating lane.

  Further, as another function of the plate-like member 70, it can be used as a pedestal for attaching the detection device 100 for detecting that the vehicle has passed over the alerting tool 60. As shown in FIG. 5, the detection device 100 extends over the entire length of the alerting tool 60 (the total length of the road width), and detects a vehicle weight and a detection signal from the detection unit 102. And a processing unit 101 for processing. On the upper surface of the plate-like member 70, a detection portion attaching groove 71 extending in the road width direction is formed, and the detection portion 102 is attached in the detection portion attaching groove 71. For example, the detection device 100 transmits a signal to an alarm device installed in a construction site by wireless or the like, thereby notifying an operator of the construction site that an intruding vehicle intruding vehicle has entered and exited the site. Thereby, the worker can be given time to evacuate from the rushing vehicle.

Further, the plate-like member 70 has a function of protecting it from acting on the locking member 95 of the connecting member R received by the vehicle weight, as will be described in detail later.
The detailed structure of the plate member 70 will be described later.

  As shown in FIG. 4, the single annular member 61 has a hollow disk-like outer shape and is integrally formed of a resin material. More specifically, the annular member 61 has a gap so that the inner first concentric ring 62A, the intermediate second concentric ring 62B, and the outer third concentric ring 62C are concentric circles. It is arranged and is connected at eight locations with a 45 degree interval in the circumferential direction by connecting portions 63 extending radially so as to connect these concentric rings 62A, 62B, 62C.

  Further, an arc-shaped inner long hole S1 having a substantially arc shape is formed between the first concentric ring 62A and the second concentric ring 62B, and the second concentric ring 62B and the third concentric ring are formed. An arcuate outer long hole S2 is formed between 62C. By having such a shape, it is firmly attached to the road surface to be laid, and even if the vehicle passes over the annular member 61, it is difficult to shift from the laid position. Further, by forming an annular shape, a vehicle that rides on the alerting tool 60 can be subjected to multiple vibrations.

  The annular member 61 is formed with a connecting member insertion hole 64 in such a manner that each of the first concentric ring 62A, the second concentric ring 62B, and the third concentric ring 62C is radially (diametrically) pierced. Has been. The connecting member insertion hole 64 is inserted with an insertion member 90 described later in detail, and the annular members 61 arranged adjacent to each other are connected by the insertion member 90.

  As shown in FIG. 3, a plate-like member 70 is attached to the annular member 61 from the upper side of the annular member. The plate-like member 70 is attached to each annular member 61.

FIGS. 6A to 6C are views showing the plate-like member 70 as a single body.
As shown in FIGS. 6A to 6C, the plate-like member 70 is formed in a flat plate shape, and is made of a resin material by integral molding. As shown in FIG. 3, the plate-like member 70 extends from the edge of one end of the annular member 61 through the center to the edge of the other end in a state assembled to the annular member 61. On the upper surface of the plate-like member 70, a detection portion mounting groove 71 extending continuously in the extending direction is formed.

  Further, as shown in FIG. 6A, an outer gripping portion 70A and an inner gripping portion 70B are formed on the back surface of the plate-like member 70, respectively. These gripping portions 70 </ b> A and 70 </ b> B are formed in an arc shape in accordance with the shape of the edge portion of the annular member 61. In addition, as shown in FIG. 6B, the gripping portions 70A and 70B are formed so as to protrude downward. More specifically, as shown in FIG. 9, the outer gripping portion 70 </ b> A has a shape of the long hole S <b> 2 so that it can be fitted into the arc-shaped outer long hole S <b> 2 of the annular member 61 from the front side (back side in FIG. 9). It is formed according to. On the other hand, the inner gripping portion 70B is formed in accordance with the shape of the inner diameter side portion so as to be fitted into the inner diameter side portion of the first concentric ring 62A.

  Further, on the back side of the plate-like member 70, as shown in FIGS. 6 (A) and 6 (B), a plurality of lightening recesses 73 defined in a rectangular shape by the horizontal ribs 74A and the vertical ribs 74B are formed.

Further, on the back side of the plate-like member 70, a connecting member mounting recess 76 formed in a mode communicating with the connecting member mounting inner hole 75B is formed.

FIG. 7 shows the insertion member 90, where (A) is a plan view, (B) is a side view, and (C) is a bottom view. In addition, the up-down direction of the insertion member 90 shall mean the direction shown in FIG.7 (C), and shall say the direction in the state where the alerting tool 60 was laid in the road.
The insertion member 90 includes a head portion 91 located at the base end portion, a main body portion 92 extending from the head portion 91 in a band shape, and a front end portion 93 located at the front end of the main body portion 92.

  The head 91 has a longer width than the main body 92 and will be described in detail later. When the main body 92 of the insertion member 90 is inserted into the connecting member insertion hole 64 of the annular member 61, the head 91 is formed. The head 91 is engaged with the edge of the connecting member insertion hole 64 to be positioned.

  The main body 92 is formed in a long strip shape, and the main body 92 is inserted into the connecting member insertion hole 64. In addition, the shape of the main body 92 substantially matches the hole shape of the connecting member insertion hole 64, and the annular member 61 does not rattle after being connected. Further, the main body 92 is made of a flexible resin material, and is manufactured by integral molding with the head 91 and the tip 93 described above.

  The distal end portion 93 is formed so as to taper toward the distal end, and the insertion member 90 can be easily inserted into the connecting member insertion hole 64. Further, the front end portion 93 is formed with a first locking portion 93 </ b> A that protrudes up and down from the upper and lower planes of the main body portion 92. The first locking portion 93A protrudes in the vertical direction with respect to the road to be laid. Further, the first locking portion 93A is formed with a side surface 93B of the first locking portion formed substantially parallel to the vertical direction.

  FIG. 8 shows the locking member 95, (A) is a front view, (B) is a plan view, (C) is a bottom view, (D) is a side view, and (E) is (B). It is YY sectional drawing. In addition, the up-down direction of the locking member 95 shall mean the direction shown in FIG.8 (C), and shall say the direction in the state where the alerting tool 60 was laid in the road.

  The locking member 95 has a locking hole 96 through which the insertion member 90 is inserted. The locking holes 96 are arranged along the road surface in a state of being laid on the road, and the insertion member 90 is inserted in the insertion direction (see FIG. 8B). The locking member 95 is integrally formed of a resin material, and the same material as the insertion member 90 is used.

  Further, as shown in FIG. 8B, the locking member 95 is formed with slits 97 on both sides in the width direction, and an elastic portion 98 is formed at the center thereof. The elastic portion 98 is easily bent in the vertical direction toward the locking hole 96 by being separated by the slit 97.

  Further, as shown in FIG. 8E, a second locking portion 98A that protrudes in the vertical direction toward the inner side of the locking hole 96 is formed inside the elastic portion 98. Further, the second locking portion 98A is formed with a side surface 98B of the second locking portion formed substantially parallel to the vertical direction. The second locking portion 98A moves up and down together when the elastic portion 98 is bent in the vertical direction.

  The connecting member R is constituted by the insertion member 90 and the locking member 95.

  Next, a procedure for connecting the annular member 61 provided with the plate-like member 70 with the connecting member R will be described with reference to FIG. FIG. 9 is an enlarged perspective view showing the state in which the two annular members 61 are connected using the connecting member R from the back side.

  The connecting member mounting outer hole 75A and the connecting member mounting inner hole 75B of the plate member 70 described above are formed in the annular member 61 in a state where the plate member 70 is assembled to the annular member 61 as shown in FIG. The connecting member insertion hole 64 is linearly aligned. In this state, the distal end portion 93 of the band-shaped insertion member 90 is inserted from the connecting member mounting recess 76, and the connecting member mounting inner hole 75B, the connecting member insertion hole 64, and the connecting member mounting outer hole 75A are arranged along the road surface of the road. In order. Further, as shown in FIG. 9, the distal end portion 93 of the insertion member 90 is similarly inserted into the holes 75 </ b> B, 64, 75 </ b> B of the adjacent annular member 61, up to the connecting member mounting recess 76 of the adjacent plate member 70. It is inserted.

  A locking member 95 is assembled to the inserted distal end portion 93 from a direction along the road surface (locking direction), and the first locking portion 93A and the second locking portion 98A are engaged with each other. 90 is locked. By inserting the locking member 95 into the insertion member 90 in this manner, the adjacent annular members 61 are connected with a predetermined interval therebetween, and the plate-like member 70 is attached and detached together so as not to be detached from the annular member 61. It becomes possible to be attached. Moreover, since the insertion member 90 is formed of a flexible resin material, the insertion member 90 can be folded to fold the attention-raising tool 60 in a compact manner.

  Further, the locking member 95 is assembled to the distal end portion of the insertion member 90 from the direction along the road surface of the road, the load direction repeatedly received from the vehicle traveling on the annular member 61, the insertion member 90 and the locking member. 95 is different from the locking direction. That is, since it differs from the load direction of the vehicle, the force acting in the engagement direction of the insertion member 90 of the connecting member R and the locking member 95 is smaller than in the case of matching as in the conventional structure. The locking member 95 is difficult to drop off from the insertion member 90.

  The first locking portion 93A and the second locking portion 98A are engaged in the extending direction in a manner aligned with the extending direction of the main body 92, and the side surface 93B of the first locking portion and the second locking portion are engaged. The side surface 98B of the part comes into contact with the extending direction of the main body part 92. Therefore, even when a vehicle load acts on the locking member 95, the first locking portion 93A moves in the vertical direction toward the second locking portion 98A when the elastic portion 98 is pressed inward and bent. Then, the engagement between the first locking portion 93A and the second locking portion 98A is further deepened. Therefore, it becomes stronger with respect to the force in the engaging direction, and the locking member 95 becomes more difficult to drop off.

  Further, since the locking member 95 is assembled in the connecting member mounting recess 76 of the plate-like member 70, the upper portion of the locking member 95 is covered with the plate-like member 70. Therefore, the vehicle load traveling on the alerting tool 60 is received by the plate-like member 70, and the vehicle load hardly acts on the locking member 95. Therefore, the locking member 95 is difficult to drop off.

  When the annular member 61 and the plate-like member 70 are connected by the insertion member 90, as shown in FIGS. 3 and 4, the plate-like member 70 is in the direction in which the annular members 61 are arranged in a line (the width direction of the road). Are arranged in a straight line in the same direction. As described above, the plate-like members 70 arranged in a straight line as described above use the plate-like member 70 as a stop line, or attach the detection unit 102 (see FIG. 5) of the detection device 100. Can do.

  According to the connection member R of the alerting tool according to the embodiment of the present invention, the direction in which the locking member 95 is locked to the insertion member 90 is the load direction (the road surface is received) received by the vehicle traveling on the annular member 61. As a reference, the direction is different from the vertical direction), that is, the direction along the road surface (the horizontal direction with respect to the road surface), so it is locked by the load received from the vehicle compared to the case where the load direction matches the locking direction. The member 95 becomes difficult to move in the locking direction. Therefore, it becomes difficult for the locking member 95 to fall off the insertion member 90 due to wear or the like. Moreover, since the protrusion part which protrudes below is not provided unlike the past, it becomes difficult for the locking member 95 to fall from the insertion member 90 by abrasion etc.

  Further, the insertion member 90 is formed with a first locking portion 93A, and the locking member 95 is locked with the first locking portion 93A in the direction along the road surface of the road and receives the load of the traveling vehicle. The second locking portion 98A that is pressed toward the first locking portion 93A and deeply engages with the first locking portion 93A is formed. The locking member 95 is less likely to fall off the insertion member 90.

  Furthermore, since the plate-like member 70 covering the upper side of the latched locking member 95 is attached to the annular member 61 together with connecting the outer peripheral ends of the adjacent annular members 61, the vehicle load is reduced. It is received by the plate-like member 70, and the vehicle load is less likely to act on the locking member 95. Therefore, it becomes difficult for the locking member 95 to fall off the insertion member 90. Moreover, since the plate-shaped member 70 is attached together with the connection of the adjacent annular members 61, the assembly workability is improved as compared with the case where the connection and the attachment are performed separately.

  In addition, since it is flexible and can be folded in such a manner that one of the adjacent annular members 61 overlaps the other, even the alerting device 60 in which the four annular members 61 are arranged is folded and made compact. be able to. Thereby, the conveyance work of the alerting tool 60 can be performed easily.

  As mentioned above, although the connection member of the alerting tool according to the embodiment of the present invention has been described, the present invention is not limited to the embodiment described above, and various modifications and changes can be made based on the technical idea of the present invention. Is possible.

  For example, in the present embodiment, the plate-like member 70 is attached to the annular member 61, but as shown in FIG. 10, adjacent annular members 61 are connected to each other without attaching the plate-like member 70 to the annular member 61. You can also. In this case, the locking member 95 is engaged at a position protruding inward from the inner peripheral edge of the annular member 61. However, as described above, by changing the load direction and the engagement direction, Compared with the technical structure, the locking member 95 can be made difficult to drop off. Similarly, the structure in which the engagement between the first locking portion 93A and the second locking portion 98A is deepened when a vehicle load is received can be sufficiently removed as compared with the structure of the prior art. Can be difficult.
