Description

[Detailed Description of the Invention] The present invention relates to a foldable stop sign board for a motorcycle that is easy to assemble and can be reliably installed on a road.

Stop display boards are placed on the road surface to prevent vehicles, especially automobiles, from colliding with other vehicles without knowing that the vehicle is malfunctioning when the vehicle, especially a car, stops due to a malfunction while driving on a highway. This system is installed on highways to notify following vehicles of the presence of your vehicle, and is required by the Road Traffic Act to be installed on expressways in the event of a vehicle breakdown.

Therefore, various types of stop display boards have been proposed in the past, but first of all, they can be folded into a small size so that they can be easily mounted on a vehicle, and they can be assembled quickly and reliably in the event of an accident, and they can be easily mounted on the road surface. It is required that the vehicle can be easily installed, and that it will not fall over or be damaged by wind, rain, or the wind pressure of a vehicle passing by the vehicle.

However, this type of stop sign board has a side length of approximately 50 cm.
Most of the products for automobiles are constructed by assembling three base pieces measuring 1.5 m in length into an equilateral triangular frame, and when folded, the length is long, making it impossible to secure sufficient storage space. It was difficult to install it on a motorcycle.

The present invention was developed in view of these circumstances, and its purpose is to create a display board body consisting of an equilateral triangular frame by pivoting at least three base bodies and connecting them in series. A stay that can be assembled to be foldable and whose length can be adjusted at the top, a slide fitting that is slidably provided on the top of the stay, and a spring that constantly urges the stay upward and presses it against a part of the motorcycle. The present invention provides a stop display board for a motorcycle that can be stably and quickly installed between the motorcycle and the road surface by using an extremely simple structure including a connecting mechanism consisting of the following.

Hereinafter, its configuration etc. will be explained in detail based on the drawings.

FIG. 1 is a partially cutaway front view showing the assembled state of the stop display board according to the present invention, and FIG. 2 is a rear view thereof.

In these figures, what is designated as a whole by reference numeral 1 is a stop display board, and this stop display board 1 includes a display board main body 3 formed by assembling six bases 2A to 2F into an equilateral triangular frame. The board main body 3 is supported by a lid of a storage cage, which will be described later, and is installed almost vertically on the road surface.

The six substrates 2A to 2F are each made of synthetic resin such as ABS resin and have approximately the same length and width, and are formed in approximately the same shape, and there is no surface on the outside from the center line in the longitudinal direction. A reflector 4 extending almost the entire length of each base is fixed.

These reflectors 4 are generally made of a red-colored plastic material, and their reflective surfaces are composed of a combination of prisms each having a set of trihedrons at right angles to each other. The existence of the stop display board 1 can be clearly confirmed from a distance even at night.

The six substrates 2A to 2F are arranged such that the lower end of the first substrate 2A overlaps the upper end on the front side of the second substrate 2B, and the second substrate 2A overlaps the upper end of the second substrate 2B.
The lower end of B overlaps the left end on the front side of the third base 2C, the right end of the third base 2C overlaps the left end on the front side of the fourth base 2D, and the right end of the fourth base 2D overlaps the left end on the front side of the fourth base 2D. The upper end of the fifth base 2E is overlapped with the lower end of the front surface of the sixth base 2E, and the overlapping parts are rotated with respect to each other using connectors 5 such as rivets. They are connected in a series by being freely connected, and the two consecutive base bodies, that is, the first and second base bodies 2A and 2B, and the fifth and sixth base bodies
The bases 2E and 2F form the hypotenuses of the triangle, and the third and fourth substrates 2C and 2D form the base.

Each of the connectors 5 connects the overlapping portions of adjacent base bodies 2A to 2F on the inner side of the center line in the longitudinal direction.

Moreover, since each connector 5 is attached via a washer 20, the washer 20 is housed in the open end of the connector insertion hole 21 (see FIG. 3) drilled in each base 2A to 2F. A counterbore 22 is formed in each case.

As appropriately shown in FIGS. 2 and 5, three engaging protrusions 6a to 6C are integrally protruded from the tip of the first base body 2A and correspond to the engaging protrusions 6a to 6C. The above 6th
As shown in FIG. 4, the tip of the base 2F has three engagement holes 7a to 7c, and an engagement portion 8 that curves along the shape of the tip of the base 2F rises toward the surface. It is set up protrudingly.

The engagement hole 7a opens to the side of the engagement portion 8, and the engagement hole 7b opens to the side of the engagement portion 8.
, 7c are formed to have a width somewhat larger than that of the engaging protrusions 6b, 6c.

Therefore, the engaging protrusions 6b, 6c are connected to the first base 2A.
The first and sixth base bodies 2A are fitted into the engagement holes 7b and 7c, respectively, by utilizing rearward elastic deformation of the base bodies 2A.

2F is relatively rotated slightly, and the engagement protrusion 6a is inserted into the engagement hole 7.
When it is completely inserted into and engaged with a from the side, both base bodies 2A
, 2F are separably connected to each other while maintaining an intersecting angle of 60 degrees.

In this case, the first base body 2A and the sixth base body 2F may be connected to each other so that they can be separated from each other. Various modifications are possible, such as configuring a connecting means with a clamping part that elastically clamps the pin.

When the display board main body 3 is assembled, the first and second base bodies 2A, 2B, the third and fourth base bodies 2C,
2D, the fifth and sixth bases 2E, 2F each need to form straight lines and form the hypotenuse and base of the triangle. A second . fourth and sixth base bodies 2B,
One end surface of 2D and 2F is in contact with the bases 2B and 2, respectively.
D, 2F as 1st. Third and fifth bases 2A, 2C, 2
A stopper 10 formed in a substantially U-shape that locks in the longitudinal direction of E is provided in a protruding manner.

Further, since the second and third base bodies 2B, 2C and the fourth and fifth base bodies 2D, 2E need to intersect at an angle of approximately 60 degrees when assembled, the second and fourth base bodies 2B, 2C, Like the stopper 10 described above, stoppers 11 formed in a substantially U-shape are integrally provided at predetermined locations on the back surface of the third base body 2D, and these stoppers 11 have a The upper right edge and the inner surface of the lower end of the fifth base body 2E are brought into contact and locked.

As is clear from FIG. 2, these stoppers 11 and the above-mentioned stopper 10 are provided on the outer side of the back surface of each of the base bodies 2A to 2E.

Therefore, each of the base bodies 2A to 2F is folded by being rotated in the same direction, that is, toward the inside of the triangle, as shown by the arrows in FIGS. 1 and 2, and in the opposite direction, that is, toward the outside of the triangle. is prevented from rotating.

Further, in the intermediate portions of the back surfaces of the first to fifth base bodies 2A to 2E and on the outer side of the longitudinal center line, when the display board main body 3 is folded, the inner surfaces of adjacent base bodies come into contact with each other. Stoppers 12 are provided to overlap each other and prevent further rotation.

Each of these stoppers 12 is formed long along the longitudinal direction of each of the base bodies 2A to 2E, and has an inner surface 12a.
is the inner surface 10a of the stopper 10 or 11 mentioned above.
, 11a are on the same plane.

Therefore, when folding the display board main body 3, the above-mentioned engagement between the engagement protrusions 6a to 6c and the engagement holes 7a to 7c is released to separate the first and sixth base bodies 2A and 2F. 'l:,
The first to fifth base bodies 2A to 2E are sequentially moved counterclockwise in FIG. 2, and the first base body 2A becomes the second base body 2B and the second base body 2B becomes the third base body 2C 1, and finally the fifth base 2.
If E is superimposed on the sixth substrate 2F, each of the substrates 2A to 2F will overlap as shown in FIGS. 5, 6, and 7, and the length of one substrate itself, in other words, the display plate It can be folded to approximately half the length of one side of the main body 3.

In this case, when the first base body 2A is completely overlapped with the second base body 2B, the inner surfaces 10at 12a of the stoppers 10.12 of the first base body 2A abut the inner edges a of the second base body 2B, respectively. Further rotation is prevented.

Such rotation is prevented by the second and third base bodies 2B.
, 2C, third substrate 2C.

2D, the fourth and fifth base bodies 2D, 2E, and the fifth and sixth base bodies 2E, 2F also have their stoppers 10 or 1
1 and 12 and the inner edge a.

In addition, in the folded state, as described above, the connectors 5 that rotatably connect adjacent base bodies to each other are rubbed inward from the center line of the base bodies, so that only the inside of each base body is exposed. They overlap completely, with every other one on the outside.

Further, sub-stoppers are provided on the first to sixth base bodies 2A to 2F.

As shown in FIGS. 1 to 3 and 5 to 7, the sub-stoppers have first, second, third, fourth and fifth sub-stops.

, 2C, 2D, 2E, and 2F, and the protrusions 25 fit into and engage with the recesses 26 during assembly, so that each base body 2A to
Deformation of the display board body 3 is prevented by restricting the rotation of the 2F.

Legs 31 and 3 that touch the road surface 30 when the stop display board 1 is installed at the lower ends of the second and fifth bases 2B and 2E.
2 are provided integrally with each other, and teeth 33 are formed at the lower ends thereof to prevent slipping on the road surface 30.

A bracket 36 is rotatably mounted on the back surface of the display board main body 3 and at the connecting portion between the third and fourth bases 2C and 2D via a connector 5 that connects both bases 2C and 2D to each other. It is arranged.

When the stop display board 1 is installed, the lower end of the bracket 36 extends downward from the lower edges of the third and fourth bases 2C and 2D, and is held on the lid of the storage case, which will be described later. There is.

Also, on one side of this bracket 36, there are shown figures 2 and 8.
As shown in the figure, the handle 37 for rotation operation is attached to the bracket 3.
The bracket 36 is bent and formed on the back side of the bracket 6.
The stopper 38 that regulates the rotation angle of the fourth base body 2D
It is bent in the direction.

The stopper 38 is provided on the arcuate upper end side of the bracket 36 and faces into a groove 39 formed on the back surface of the fourth base 2D.
When rotated, it is configured to move along the arc portion 39a of the groove 39.

The stopper 38 comes into contact with the lower edge P1 of the groove 39, thereby holding the bracket 36 at the set position.
By coming into contact with the upper edge P2, the bracket 36 is housed on the back surface of the fourth base 2D.

As shown in FIG. 9, the storage case 40 is composed of a deep box-shaped case body 41 made of synthetic resin, and a shallow-bottom box-shaped lid 42 that covers the opening of the case body 41. In this case 40, a folded stop display board 1 is housed as shown in FIG.

The lid body 42 is used to stably support the stop display board 1 when the stop display board 1 is installed.

Therefore, side walls 43a, 43b facing each other in the longitudinal direction
The plate thickness of the bracket 36 (the eighth
A pair of protrusions 44a are spaced apart slightly from each other (see figure).
, 44b and 45a, 45b are integrally protruded, and these protrusions 44a, 44b and 45a
At t 45 b, both sides of the lower end of the bracket 36 are fixedly held.

Further, as shown in FIGS. 1 and 2, a slip prevention member 46 made of rubber or the like is fixed to the surface of the lid 42 to prevent slipping on the road surface 30.

The top back surface of the stop display board 1 having the above structure is further removably connected to a part of the motorcycle, for example, a license plate 50 shown by chain lines in FIGS. A connecting mechanism 51 is provided between the road surface 30 and the road surface 30 .

This connecting mechanism 51 has a length approximately equal to that of the sixth base body 2F, and the stay 5 is formed into a substantially U-shape as a whole by bending both sides excluding the upper end at approximately right angles toward the back side.
2.

The stay 52 has a communication hole 53 that extends long in the longitudinal direction of the stay 52 slightly toward the negative side from the center, and is bent toward the center of the upper end and extends further upward. A connector which is fitted into and engaged with the communication hole 53 has a large number of locking holes 54, each of which has one end communicating with the side surface near the center of the hole 53 and is inclined upward to the right when viewed from the front of the stop display board 1. 55, a washer 49, and a plate 56, it is connected to the back surface of the upper end of the sixth base 2F so as to be vertically movable and rotatable.

The connector 55 is protruded from the rear surface of the upper end of the sixth base body 2F at a position shifted inward from its center line, and the washer 49 is caulked and fixed to the tip thereof.

The plate 56 is formed into a rectangular shape and is interposed between the stay 52 and the washer 49, and has an oblique hole 5 which is inclined in the same direction as the engagement hole 54 and into which the connector 55 is slidably inserted.
7.

The stay 52 is positioned by selectively engaging the connector 55 into any one of the plurality of engagement holes 54, and its length and height are set.

As appropriately shown in FIG. 10, a slide fitting 58 formed by bending a metal plate into a substantially C-shape is slidably fitted to the upper end of the stay 52.

The slide fitting 58 is always urged upward by a spring 61 and is prevented from coming off the stay 52 by coming into contact with a stopper 59 protruding from the upper end of the stay 52.

The spring 61 is formed by bending a band-shaped spring material into a substantially elliptical shape, and its both ends are fixed to the upper end of the stay 52, and the center part is fixed to the lower surface of the slide fitting 58.

Further, a substantially hook-shaped receiving portion 60 that extends rearward and has an upwardly bent tip is integrally formed at the lower end of the back surface of the slide fitting 58. It is pressed and engaged with the lower edge of the license plate 50 from below.

In addition, on the back surface of the sixth base 2F, as shown in FIGS. 2 and 7, there is a pair for storing and fixing the coupling mechanism 51 on the back surface of the base 2F when the stop display board 1 is stored. Stoppers 63 and 64 are integrally provided.

Therefore, one stopper 63 is located approximately at the center of the back surface of the sixth base 2F and extends long in the longitudinal direction of the base 2F, and the other stopper 64 extends along the inner edge of the lower end. The stay 52 is placed between the stoppers 63 and 64 of
By inserting the lower end of the stay 52, in other words, the connecting mechanism 51 is restricted from moving in the left-right direction.

Naturally, the upper end portion of the stay 52 is restricted from moving in the left-right direction by the connector 55.

In this case, the connector 55 is located above the bent portion 53a (see FIG. 7) of the communication hole 53 bored in the stay 52.

Note that 70 is a stopper for regulating the downward movement of the slide needle 58 and preventing the spring 61 from breaking.

When the stop display board 1 having the above configuration is installed on the road surface 30, the lid body 42 is placed below the license plate 50 with the opening facing upward, and an equilateral triangular frame is placed on the lid body 42. Place the assembled stop display plate 1 on the body, insert both ends of the stopper 36 between the protrusions 44a and 44b and 45a and 45b of the lid body 42, and then insert the slide fitting 5.
8 engages the lower edge of the license plate 50, and while maintaining this state, pushes up the stay 52 upward against the spring 61, and at a position where the spring 61 is sufficiently compressed,
The connector 55 may be inserted into the engagement hole 54 corresponding to this position.

As a result, the slide fitting 58 is pressed against the license plate 50 by the force of the spring 61, and the reaction force acts on the stop display plate 1.

Therefore, the stop display board 1 is pressed downward, and the road surface 30
It is installed in a stable state between the license plate 50 and the stop display plate 1, and there is no risk of it falling over due to wind and rain or the wind pressure of a vehicle passing on the side of the stop display plate 1, and a good and accurate warning function is ensured.

In addition, when installing the stop display board 1, the stopper 10,
Each base 2A ~ until the rotation is restricted by 11 and 12.
If all 2Es are sequentially moved in the same direction, they will naturally be assembled into a triangular shape, so the assembly work is easy and anyone can quickly install it without getting confused.

In addition, if all the base bodies 2A to 2E are sequentially moved in the same direction and overlapped with each other, they can be folded to approximately half the length of one side of the triangle, making the scale convenient to carry and wide. Since it does not require storage space, it is suitable for mounting on a motorcycle.

In addition, when removing the coupling mechanism 51 from the license plate 50, push down the slide fitting 58 against the spring 61, and move the stay 52 counterclockwise in FIG. When the connector 55 is rotated to release the engagement state between the connector 55 and the engagement hole 54, the connector 55 is positioned in the communication hole 53 and the stay 52 is lowered, so that it can be easily removed from the license plate 50. I'll come.

In addition, although the above embodiment used the spring 61 formed by curving a band-shaped spring material into an oval shape, the present invention is not limited to this.
For example, instead of using a torsion coil spring, it is possible to use an appropriate spring.

Further, in the above embodiment, the case where the display board main body 3 is assembled with six substrates 2A to 2F has been described, but the present invention is not limited to this, and as in the past, three
It may be configured to be foldable with a single base body.

In this case, the length of the stay can be approximately doubled, which has the advantage of expanding the number of connection points of the connection mechanism to the motorcycle.

As explained above, according to the stop display board for motorcycles according to the present invention, a foldable display board main body is formed by a plurality of base members, and a length-adjustable stay is attached to the top back surface of the display board body, and a length-adjustable stay is attached to the top of the stay. A coupling mechanism is provided that includes a slidable slide fitting and a spring that constantly biases the slide fitting upward, and the spring connects the receiving portion provided on the slide fitting to one side of the motorcycle. Since the stop display board is press-fitted from below, the stop display board can be stably installed on the road, and can be prevented from falling, rotating, moving, etc. due to wind pressure or the like.

In addition, since the structure of the coupling mechanism is simple and does not use any screws or the like, it is easy to attach and detach from a motorcycle, and its practical effects are very large.
