Further, as shown in the figure, the sign display portion A of the second reflector 2 is displayed in black (parts indicated by dots) and yellow (parts other than dots) V-shaped stripes. The sign display portion A of the first reflector 1 (not shown) has the same stripe pattern as the sign display portion A of the second reflector 2. The sign display section A may be changed in color or pattern, or may be displayed with characters such as "attention", "under construction", "danger", and the like. It is preferable that 2 has different display contents.

The bottom plate 3 has first and second reflectors 1 and 2 at both end edges on the first and second reflectors 1 and 2 via hinges 10 and 10.
2 is pivotally connected to the lower edges 6, 7 of
An intermediate portion has a pivot shaft 8 parallel to the lower edges 6, 7 of the first and second reflectors 1, 2 and is capable of swinging upward. In other words, the bottom plate 3 is composed of two trapezoidal metal plates 3a,
3a are connected by a hinge 9 and two metal plates 3
The hinge members 9 of a and 3a are pivoted upward by a lifting member 12 (described later). Note that the pivot 8 is a hinge 9
Of the shaft.

The pulling member 12 has a lower end 12a attached near the pivot 8 of the bottom plate 3 and an upper end 12b extending to an upper portion of the first and second reflectors 1, 2. An operation ring 13 is provided at the upper end.

More specifically, the lifting member 12
Consists of wire, rope, chain, etc.

a, 3a (in the illustrated example, the metal plate 3a on the first reflection plate 1 side), and is prevented by the retaining ring 14 or the like. The upper end 12b passes through a cutout 15 formed at the upper end of the second reflector 2, and the operation ring 13 is exposed to the outside.

As shown in FIGS. 4 and 5, by pulling up the operating ring 13 of the pull-up member 12, the bottom plate 3 connected to the pull-up member 12 swings upward to form an inverted V-shape. Become. That is, one of the metal plates 3a connected to the lifting member 12
Is lifted upward, and the other metal plate 3a is pulled upward in conjunction with it. When the bottom plate 3 swings upward, the first and second reflectors 1 and 2 swing inward, and the lower edges 6 and 7 approach each other, so that the unfolded state changes from the rising state to the folded state. Can be switched.

Conversely, when switching from the folded state to the unfolded rising state, the lower edges 6, 7 of the first and second reflectors 1, 2 are manually swung in a direction to separate them from each other. Then, the intermediate portion of the inverted V-shaped bottom plate 3 swings downward, the bottom plate 3 becomes an open leg shape, and the safety sign board is in a standing state.

FIG. 6 shows a use state of the safety sign device of the present invention. For example, when construction is performed in the manhole B, a plurality of safety sign devices are developed around the opening of the manhole B (on the road surface). And the adjacent first reflectors 1
1 are connected by a horizontal rod 16 (so-called cone bar) to form an enclosure. The horizontal rod 16 includes a rod 16a alternately arranged in black and yellow, and loops 16 provided at both ends of the rod 16a.
b, 16b, and the ring members 16b, 16b are hooked on the upper portions of the adjacent first reflection plates 1, 1 to thereby form the rod member 16
a is supported substantially horizontally.

As described above, the safety signs installed on the construction site include the sign display portions A, 1 of the first and second reflectors 1, 2.
A alerts pedestrians and drivers by A
By connecting at ..., an off-limits area is provided. At night, the sign display area A,
Since A is reflected and glows, pedestrians and drivers can detect danger from a distance. Furthermore, 2 of the bottom plate 3
The metal plates 3a, 3a also serve as weights for preventing the safety sign from falling over due to wind, movement, or the like, thereby improving safety.

Next, FIG. 7 shows an embodiment of a storage box capable of storing a plurality of safety signs C. The storage box comprises a case main body 18 having a front opening D, and a case main body. A first reflection plate 1 and a first reflection plate 20 whose upper portions are pivotally connected to each other so as to be freely deployable and foldable. 2 reflector 2
Are inserted into the hole 11 formed at at least one of the upper ends thereof to store a plurality of safety sign tools C. The specific configuration of the safety marker C is the same as the configuration of the safety marker described with reference to FIGS.

The case body 18 includes upper and lower walls 21 and 22 and left and right side walls.
It is composed of 23, 23 and a rear wall 19 and has a front opening shape. The fall prevention rod 20 is protruded from the upper part of the rear wall 19 at the left and right intermediate position, and falls down with the upper edge of the hole 11 when the folded safety sign C is placed on the lower wall 22 in the case body 18. The height of the prevention rod 20 is set such that the upper edges thereof come into contact with each other. Also, the fall prevention rod
The length 20 is shorter than the front-rear width of the left and right side walls 23, 23 of the case body 18. It is also possible to provide a lid for covering the front opening D, or to provide an upper projection (for preventing the hole 11 from being removed) at the tip of the fall prevention rod 20.

Thus, the safety sign C is folded and stored in the case body 18 sequentially. At this time, the front and rear widths of the safety sign C in the folded state (the first and second reflectors 1 and 2). The distance between the lower end edges) is considerably smaller (thinner) than in the unfolded rising state, and the height is only slightly higher than in the unfolding rising state. Can be stored compactly (FIGS. 4 and 5).
reference).

Therefore, it is possible to sufficiently store a plurality of safety sign tools C... Without making the storage space of the case body 18 excessively large. If the size of the storage box is set so that... Can be stored, it becomes easy to count when a large number of the safety sign tools C are required.

The present invention is not limited to the above-described embodiment. For example, the first reflecting plate 1 may have the same trapezoidal shape as the second reflecting plate 2, and the respective upper edges may be pivotally connected. In this case, a hole 11 that penetrates both the first and second reflectors 1 and 2 is formed.

[0024]

Since the present invention is configured as described above, the following effects can be obtained.

According to the first or second aspect of the present invention, in the unfolded rising state (use state), the first and second flat reflecting plates 1 and 2 are formed.
The two sign display parts A, A have good visibility from pedestrians and drivers, and can be folded and made thin and compact after use.
The storage space of the storage place can be reduced.

According to the second aspect of the present invention, the safety sign can be easily and quickly switched from the deployed state to the folded state by pulling up the lifting member 12.

Since the first and second reflectors 1 and 2 and the bottom plate 3 (weight metal plates 3a, 3a) are integrated (according to claim 3), the weight of other members is unnecessary. In addition, loading and unloading operations to and from a vehicle can be performed quickly to save labor, and an extra storage space can be reduced. In addition, it can be used simply by putting the safety sign in the unfolded and upright position. It is not necessary to attach the weight of other members to the safety cone one by one as in the past. The safety can be improved without forgetting to put on the vehicle, and the safety sign carried at the site can be quickly installed.

According to the fourth aspect of the present invention, since a plurality of compact safety signs C in a folded state can be stored together while being held by the fall prevention rod 20, loading and stacking on a transport vehicle is possible. The unloading operation can be performed quickly and labor can be saved. In addition, since the case bodies 18 can be stacked on each other, the case bodies 18 can be arranged and stored in a loading space or a storage / storage location of the transport vehicle.
