Description

TECHNICAL FIELD The present invention relates to a cone that is installed on a road surface or the like and teaches predetermined information to passersby.

BACKGROUND ART Conventionally, cones (road cones) are known that include a substantially conical main body and a pedestal connected to the lower edge of the main body, and are erected on a road surface or the like to guide traffic. In addition, the cone is divided into three or more parts in the vertical direction and can be expanded and contracted up and down, and when the cone is not in use, the upper part is housed inside the lower part so that the cone can be contracted downward. When using a cone, there is a technique in which the cone is extended upward by making the upper part protrude upward from the lower part (see, for example, Patent Document 1).

Japanese Patent Application Publication No. 2014-202006

By the way, when storing the cone of Patent Document 1 when not in use, it is conceivable to shrink the cone in order to minimize the space required for installing the cone. However, when the cone of Patent Document 1 is in a contracted state, three or more parts constituting the cone are completely separated. For this reason, when transporting and storing multiple cones together, it is not possible to simply stack the cones in a deflated state; instead, it is necessary to pack the cones in a deflated state before stacking them, or , it is conceivable to extend the cone and stack the parts of the cone in a state where they are connected to each other. Here, there is a need to improve the transportation efficiency and storage efficiency of corn when it is not in use.

The present invention has been made to solve the above-mentioned problems, and its purpose is to provide a cone that can improve transportation efficiency and storage efficiency when not in use. be.

Below, each means suitable for solving the above problems will be explained in terms of sections. Note that effects specific to the corresponding means will be added as necessary.

Means 1. A cone including a main body having a substantially conical outer shape,
The cone is
a lower part including a lower body part that is a lower part of the main body part;
comprising an upper body part which is an upper part of the body part, and an upper part detachably provided to the upper part of the lower part,
In a separated state where the cone is separated into the lower part and the upper part, the upper part is configured to be housed inside the lower part,
The upper part is provided with a locking protrusion that protrudes from the inner surface of the upper body part,
The lower part is
a receiving part that supports the upper part by coming into contact with the lower edge of the upper body part in a connected state in which the lower part and the upper part are connected;
a regulating portion that substantially contacts the inner surface of the upper body portion in the connected state;
The regulating portion is provided with a locking hole that penetrates the lower body portion in an inner and outer direction,
In the connected state, the locking protrusion of the upper part is inserted into the locking hole, and the locking protrusion and the peripheral edge of the locking hole are substantially locked ,
The peripheral edge of the locking hole in the regulating part is a thick part that is thicker than the general part that is the other part of the regulating part,
A portion of the restriction portion located between the locking hole and the upper edge of the restriction portion and located above the thick portion adjacent to the upper edge of the locking hole has an outer surface. The cone is configured to be one step lower toward the inner side of the lower body portion than the outer surface of the thick portion .

According to means 1, by separating the cone into a lower part and an upper part and storing the upper part inside the lower part, the cone can be compactly packed when not in use. Furthermore, by stacking the upper parts and stacking the lower parts so as to surround the upper part, a plurality of cones can be compacted. Therefore, it is possible to improve transportation efficiency and storage efficiency when not in use.

In addition, the lower part includes a receiving part that contacts and supports the lower edge of the upper body of the upper part when the cone connecting the lower part and the upper part is in a connected state, and the receiving part is provided with a receiving part that contacts and supports the lower edge of the upper body of the upper part, and is directed downward with respect to the upper part. When force is applied, downward displacement of the upper part can be effectively restricted. Furthermore, the lower part is provided with a regulating part that substantially contacts the inner surface of the upper body of the upper part when the cones are connected, so that when the cones are connected, the upper part is horizontal to the lower part. It is possible to prevent a situation in which the object falls off due to relative displacement. In particular, since the regulation part of the lower part fits inside the upper body part, it is possible to avoid a situation where the upper part falls off inside the lower part, and the cone can be used as a connecting state. This makes it possible to more reliably prevent a situation in which the cone is inadvertently separated during the process. Therefore, even if a downward force is applied to the upper parts of the connected cones (for example, even if a cone bar is provided to span the upper parts of a pair of cones), the cone The connected state (usage pattern) can be maintained reliably, and the cone can be installed on a road surface or the like to reliably perform the function of teaching predetermined information to passersby.

Furthermore, the upper part is provided with a locking protrusion that protrudes from the inner surface of the upper body, and the regulating part of the lower part is penetrated in the inner and outer directions of the lower body and is locked with the locking protrusion. A locking hole is provided. For this reason, for example, compared to a configuration in which the locking protrusion is locked in a recess that fits within the thickness of the restricting part instead of a locking hole that penetrates the restricting part, the locking protrusion can be fixed without making the restricting part thick. The protrusion length can be made as large as possible, and the locked state can be stabilized.

Further, the upper part and the lower part can be connected by simply inserting the regulating part of the lower part inside the upper body part of the upper part and inserting the locking protrusion into the locking hole. Therefore, for example, when connecting the upper part and the lower part, a configuration that requires an operation other than the operation of covering the upper part from above the lower part (for example, the lower edge of the upper part and the lower part (e.g., screwing the upper edge part together), it is possible to improve the connection workability.

In addition, it is possible to prevent the locking holes and locking protrusions from being exposed on the outer surface side of the cones when the cones are connected. Therefore, it is possible to suppress the formation of a step or a recess on the outer surface of the main body of the connected cone, and it is possible to prevent other objects from getting caught or dust, etc. to accumulate on the step or recess. It is possible to improve the design of the cone while avoiding such situations.

In addition, as described above, since the lower part is provided with the receiving part and the regulating part, even if a downward force is applied to the upper part when the cone is connected, the locking protrusion and the restricting part It is possible to avoid placing a relatively large load on the peripheral edge of the stop hole. Therefore, deterioration and damage to the locking protrusion and the peripheral edge of the locking hole can be prevented, and as a result, durability can be improved.

Furthermore, a receiving part is provided between the lower body part and the regulating part, so that even if the lower body part is slightly deformed due to a force being applied to the lower body part from the side, the Deformation can be made difficult to spread to the regulating portion. Therefore, for example, the regulating part of the lower part and the part of the upper body part where the locking protrusion is provided are separated, the regulating part is deformed, and the locked state of the locking protrusion is released. Such situations can be prevented. In addition, since the regulating part of the lower part fits inside the upper part when the cone is connected, even if a force is applied from the side to the upper body when the cone is connected, it will not engage. It is possible to avoid a situation in which the upper body portion is deformed to the side where the locked state between the locking projection and the locking hole is released.

Note that the height of the upper part may be the same as or higher than the height of the lower part to the upper surface of the receiving part (and lower than the height of the lower part). In this case, the effect of storing the upper part inside the lower part to improve transportation efficiency is further achieved.
Moreover, the rigidity of the peripheral edge of the locking hole can be increased to make it difficult to deform, and as a result, the locked state of the locking protrusion can be stabilized. In addition, when forming a thick part by increasing the thickness of the regulating part outward compared to the general part, the regulating part should come into contact with the inner surface of the upper body part of the upper part at the thick part. becomes. For this reason, for example, compared to the case where the entire outer surface of the restriction part comes into contact with the inner surface of the upper body part of the upper part, when connecting the upper part and the lower part, the restriction part cannot be inserted inside the upper body part. This makes it possible to improve the connection workability.
Furthermore, when connecting the upper part and the lower part, it becomes easier to insert the locking protrusion into the locking hole, and it is possible to improve the connection workability.

Means 2. The cone according to means 1 , wherein the lower part and the upper part have a different coloring and at least one of different materials .

According to means 2, the coloring and material can be selected for the lower part and the upper part, respectively, and convenience can be improved. That is, for example, by coloring the upper part and the lower part differently, it is possible to easily recognize that the upper parts assembly is inserted inside the lower parts assembly. Furthermore, it is possible to diversify the visibility mode, and it is also possible to change the visibility mode greatly by simply replacing the upper part and the lower part without changing the other, and it is easy to replace them. It is possible. Therefore, for example, the lower part is of one type, but there are multiple types of upper parts in different colors, and the upper part can be selected appropriately depending on the application, etc., to improve versatility and convenience. can be achieved.
In addition, for example, by making the upper part and the lower part different from each other, it is possible to select a material suited to the required function of each part. For example, the lower part, which often comes into contact with workers' feet and wheels, is made of a relatively soft resin to prevent damage, while the upper part is made of a relatively hard resin. Compared to the case where the upper part is also made of soft resin, it is possible to adopt a structure that makes the connection work with the lower part (the work of inserting the regulating part inside the upper body part) relatively smooth. In addition, by making (at least a part of) one of the upper part and the lower part transparent resin, it is possible to reduce costs compared to the case where the entire part is made of transparent resin, and to prevent suspicious objects from inside the cone. It can be made easier to discover that it is installed.

Means 3. For an upper part assembly in which a plurality of the cones consisting of a specific number are separated into the lower part and the upper part, and the separated plurality of upper parts consisting of the specific number are stacked vertically, When a lower parts assembly in which a plurality of separated lower parts consisting of the specific number are stacked vertically is arranged so as to surround the upper parts assembly, the entire upper parts assembly becomes the lower parts assembly. The cone according to means 1 or 2, characterized in that it is configured to be housed inside the body .

According to means 3 , there is an upper part assembly in which a plurality of upper parts made up of a specific number of separated parts are stacked one above the other, and a lower part set in which a plurality of lower parts made up of a specific number separated are stacked one on top of the other. By arranging the body so as to surround the upper parts assembly, a plurality of cones consisting of a specific number can be compactly grouped. Therefore, it is possible to improve transportation efficiency and storage efficiency when not in use.

Note that "the entire upper parts assembly is housed inside the lower parts assembly" means that a plurality of upper parts assemblies consisting of a specific number are housed inside a plurality of lower parts assemblies consisting of a specific number. Even if the upper parts assembly and the lower parts assembly are not brought into contact with each other, each of the upper parts assembly and the lower parts assembly can be grounded to the installation surface, and the upper parts assembly is intended not to protrude upward from the lower parts assembly .

It has become so. This prevents all the locking protrusions 8 of the upper part 5 on the upper side from coming into pressure contact with the outer surface of the upper body part 2b of the upper part 5 on the lower side when the upper parts 5 are stacked one on top of the other. At the same time, the locking protrusion 8 of the upper part 5 on the upper side and the outer surface of the upper body part 2b of the upper part 5 on the lower side are configured to contact or be close to each other (see FIG. 7).

The lower part 4 includes a receiving part 11 that supports the upper part 5 by contacting the lower edge of the upper body part 2b when the cone 1 is connected, and a receiving part 11 that supports the upper part 5 by contacting the lower edge of the upper body part 2b when the cone 1 is connected. and a regulating portion 12 that abuts. As shown in FIG. 4, in this embodiment, the upper edge of the lower body part 2a and the lower edge of the upper body part 2b have the same diameter. Furthermore, the thickness of the lower body portion 2a and the thickness of the upper body portion 2b are the same. In the connected state of the cone 1, the lower edge of the upper body 2b is in contact with and supported by the upper edge of the lower body 2a. In this embodiment, the receiving portion 11 is configured by the upper edge of the lower body portion 2a.

Further, as shown in FIGS. 4 and 5, the regulating portion 12 of this embodiment has the upper edge portion of the lower body portion 2a protrude inwardly by the thickness of the lower body portion 2a. It has a substantially circular frame shape that protrudes upward from the lower body part 2a, following the shape (inclination and curvature) of the lower body part 2a. As shown in FIGS. 2, 5, etc., the restriction portion 12 is provided with a locking hole 13 that penetrates the lower body portion 2a in the inner and outer directions. The locking holes 13 are provided at three locations corresponding to the locking protrusions 8 of the upper part 5.

Further, as shown in FIG. 2 and the like, the peripheral edge of the locking hole 13 in the regulating part 12 is a thick part 15 that is thicker than the general part 14 that is the other part of the regulating part 12. . In this embodiment, the thickness of the thick part 15 is the same as the thickness of the lower body part 2a, and in the range targeted by the thick part 15 in the circumferential direction of the lower body part 2a, the restricting part 12 is A thick portion 15 extends from the lower edge to the upper edge. Furthermore, as shown in FIG. 5, the thick portion 15 is configured by increasing the thickness of the regulating portion 12 toward the outside compared to the general portion 14. In addition, the lower part 4 includes an upper edge protrusion 16 that protrudes inward from the upper edge of the restriction part 12, and the upper edge of the lower part 4 (restriction part 12) is reinforced. There is.

As shown in FIGS. 3 and 4, when the cone 1 is connected, the locking projection 8 of the upper part 5 is inserted into the locking hole 13, and the locking projection 8 and the peripheral edge (upper edge) of the locking hole 13 are inserted into the locking hole 13. ) are in a substantially locked state (a state in which the locking protrusion 8 comes into contact with the upper edge of the locking hole 13 when a force that vertically separates the upper part 5 and the lower part 4 is applied). Ru. The protrusion length of the locking protrusion 8 from the upper body portion 2b is longer than the thickness of the regulating portion 12 (thick wall portion 15), and as shown in FIG. 4, when the cone 1 is connected, the locking protrusion 8 projects slightly inward from the inner surface of the upper body portion 2b. In addition, as shown in FIG. 2 and the like, on the outer surface side of the lower part 4, there is a hole corresponding to a predetermined position of the upper edge of the lower body part 2a (in this example, the center part in the width direction of the predetermined locking hole 13). A lower positioning portion 17a (in this example, a protruding shape) is provided. Further, on the outer surface side of the upper part 5, an upper positioning portion 17b (in this example In this case, a protruding shape) is provided. As shown in FIG. 1, when connecting the lower part 4 and the upper part 5, the locking protrusion 8 can be accurately locked by aligning the lower positioning part 17a and the upper positioning part 17b. It will be inserted into the hole 13.

As shown in FIGS. 2, 3, 6, etc., the pedestal portion 3 includes a substantially disk-shaped horizontally extending portion 21 extending outward from the lower edge of the lower body portion 2a, and a horizontally extending portion 21 extending outwardly from the lower edge of the lower body portion 2a. a vertically extending portion 22 having a substantially circular frame shape extending downward from the outer edge; a base plate portion 23 having a generally square outer shape in plan view and protruding outward from the lower edge of the vertically extending portion 22; The base plate part 23 includes a substantially rectangular frame-shaped skirt part 24 extending downward from the outer edge part of the base plate part 23.

As shown in FIG. 3 and the like, the lower part 4 includes a lower stacking rib 25 that projects downward from the lower surface of the horizontally extending portion 21. As shown in FIG. The lower stacking ribs 25 are provided at four locations at equal intervals in the circumferential direction of the lower body portion 2a. Further, the lower stacking rib 25 has a substantially cross-shaped horizontal section, and is connected to the inner surface of the vertically extending portion 22 . Further, the lower stacking ribs 25 are configured to be located on the outer side of an imaginary plane that extends the inner surface of the lower body portion 2a downward. In addition, the lower edge of the lower stacking rib 25 is located slightly above the lower edge of the vertically extending portion 22 (the upper surface of the base plate portion 23).

When the lower parts 4 are stacked together, the lower edge of the lower stacking rib 25 of the upper lower part 4 is supported by coming into contact with the upper surface of the horizontally extending part 21 of the lower lower part 4. (See Figure 7). This prevents the inner surface of the upper lower part 4 from coming into pressure contact with the outer surface of the lower lower part 4 when the lower parts 4 are stacked together, and the inner surface of the upper lower part 4 ( The regulating portion 12) and the outer surface of the lower body portion 2a of the lower lower part 4 are configured to abut or be close to each other. Hereinafter, the plurality of lower parts 4 stacked vertically will also be referred to as a "lower parts assembly 26".

Incidentally, the increase in height when the lower part 4 is stacked on the lower part 4 is slightly larger than the increase in height when the upper part 5 is stacked on the upper part 5. . In addition, when the lower parts 4 are stacked, the locking hole 13 of the upper lower part 4 is located above the upper edge of the lower lower part 4 (regulating part 12), and the lower part When taking out the lower parts 4 of the uppermost stage one by one from the assembly 26, put your fingertips on the upper edge of the locking hole 13 through the locking hole 13 of the lower part 4 of the uppermost stage. Part 4 can be lifted.

As shown in FIGS. 3, 6, etc., on the lower surface side of the base plate part 23, a substantially circular frame-shaped support rib protrudes downward from the base plate part 23 along the lower edge of the vertically extending part 22. 27, and a reinforcing rib 28 extending from the outer surface of the support rib 27 to the hem 24. The lower edge of the support rib 27 is at the same height as the lower edge of the hem 24, and the lower edge of the reinforcing rib 28 is inclined upwardly toward the outside. Note that the support ribs 27 are located on the outer side of the imaginary plane that extends the inner surface of the vertically extending portion 22 downward, and when the lower parts 4 are stacked, the support ribs 27 of the upper lower part 4 However, it is configured so as not to interfere with the horizontally extending portion 21 and the vertically extending portion 22 of the lower part 4 on the lower side.

As described above, the cone 1 can be separated into the lower part 4 and the upper part 5, and the upper part 5 can be accommodated inside the lower part 4. The height of the upper part 5 in this embodiment is approximately the same as the height to the upper surface of the receiving part 11 of the lower part 4, and the entire upper part 5 can be accommodated inside the lower part 4. In particular, as shown in FIG. 7, in this embodiment, a maximum of 10 cones 1 are separated into a lower part 4 and an upper part 5, and the 10 upper parts 5 are stacked on top of each other to form an upper part assembly 9. Even if the lower parts assembly 26 is formed by stacking ten lower parts 4 to surround the upper parts assembly 9, the entire upper parts assembly 9 is inside the lower parts assembly 26. It is designed to be accommodated in

When the upper parts assembly 9 made up of the 10 upper parts 5 is accommodated inside the lower parts assembly 26 made up of the 10 lower parts 4, the upper parts assembly 9 and the lower parts assembly 26 are separated from each other. It is possible to ground each of the upper parts assembly 9 and the lower parts assembly 26 to the installation surface without making them contact each other and without causing the upper parts assembly 9 to protrude upward from the lower parts assembly 26. It becomes. In this embodiment, there is a distance of about 1 mm between the upper edge (upper edge protrusion 16) of the lowermost part 4 of the lower parts assembly 26 and the upper part 5 of the uppermost part 9. The setting is such that a gap is formed.

In addition, as shown in FIG. 6, when the connected cones 1 are stacked vertically, the lower edge of the lower stacking rib 25 of the upper lower part 4 It is adapted to be supported by coming into contact with the upper surface of the extending portion 21. In addition, when the connected cones 1 are stacked vertically, the regulating portion 12 and the locking protrusion 8 of the upper cone 1 come into contact with the outer surface of the lower cone 1 (upper body portion 2b). Or, although they are close to each other, they are not pressed together.

As described in detail above, according to the present embodiment, the cone 1 is separated into the lower part 4 and the upper part 5, and the upper part 5 is housed inside the lower part 4. Cone 1 can be packed compactly. Furthermore, the 10 cones 1 are separated into an upper part 5 and a lower part 4, and the 10 separated upper parts 5 are stacked vertically to form an upper part assembly 9. By arranging a lower part assembly 26 in which the lower parts 4 are stacked one above the other so as to surround the upper parts assembly 9, ten cones 1 can be compactly assembled. Therefore, it is possible to improve transportation efficiency and storage efficiency when not in use.

Further, the lower part 4 includes a receiving part 11 that contacts and supports the lower edge of the upper body part 2b of the upper part 5 when the cone 1 is connected to the lower part 4 and the upper part 5. , when a downward force is applied to the upper part 5, the downward displacement of the upper part 5 can be effectively restricted. Further, the lower part 4 is provided with a regulating part 12 that substantially contacts the inner surface of the upper body part 2b of the upper part 5 when the cone 1 is connected. It is possible to prevent a situation in which the part 4 is displaced horizontally relative to the part 4 and falls off. In particular, since the restricting part 12 of the lower part 4 is configured to fit inside the upper main body part 2b, it is possible to avoid a situation where the upper part 5 falls off to the inner side of the lower part 4, and the cone 1 can be It is possible to more reliably prevent a situation in which the cone 1 is inadvertently brought into a separated state while being used in a connected state. Therefore, even if a downward force is applied to the upper part 5 of the cone 1 in the connected state (for example, even if a cone bar is provided so as to span between the upper parts 5 of a pair of cones 1) ), the connected state (usage pattern) of the cone 1 can be maintained reliably, and the cone 1 can be installed on a road surface or the like to reliably perform the function of teaching predetermined information to passersby.

Furthermore, the upper part 5 is provided with a locking protrusion 8 that protrudes from the inner surface of the upper main body part 2b, and the restricting part 12 of the lower part 4 is provided with a locking protrusion 8 that penetrates in the inner and outer directions of the lower main body part 2a. A locking hole 13 is provided which is in a locked state. For this reason, for example, the restricting portion 12 may be made thicker than a configuration in which the locking protrusion 8 is locked in a recess that fits within the thickness of the restricting portion 12 instead of in the locking hole 13 that penetrates the restricting portion 12. Therefore, the protrusion length of the locking protrusion 8 can be made as large as possible, and the locking state can be stabilized.

Further, the upper part 5 and the lower part 4 can be connected by simply inserting the regulating part 12 of the lower part 4 inside the upper body part 2b of the upper part 5 and inserting the locking protrusion 8 into the locking hole 13. Can be done. Therefore, for example, when connecting the upper part 5 and the lower part 4, a configuration that requires an operation other than the operation of covering the upper part 5 from above the lower part 4 (for example, the lower edge of the upper part 5 The connection workability can be improved compared to the case where the lower part 4 is screwed to the upper edge of the lower part 4, etc.).

In addition, when the cone 1 is in the connected state, the locking hole 13 and the locking protrusion 8 can be prevented from being exposed to the outer surface of the cone 1. Therefore, it is possible to suppress the formation of a step or a recess on the outer surface side of the main body 2 of the connected cone 1, and it is possible to prevent another object from getting caught in the step or the recess, or to prevent dust, etc. It is possible to improve the design of the cone 1 while avoiding situations such as accumulation.

Further, as described above, since the lower part 4 is provided with the receiving part 11 and the regulating part 12, even if a downward force is applied to the upper part 5 in the connected state of the cone 1, the locking can be prevented. It is possible to avoid placing a relatively large load on the protrusion 8 and the peripheral edge of the locking hole 13. Therefore, deterioration, damage, etc. of the locking protrusion 8 and the peripheral portion of the locking hole 13 can be suppressed, and as a result, durability can be improved.

Further, a receiving part 11 is provided between the lower body part 2a and the regulating part 12, and for example, when force is applied to the lower body part 2a from the side, the lower body part 2a is slightly deformed. Even if this occurs, the deformation can be made difficult to spread to the regulating portion 12. Therefore, for example, the regulating part 12 of the lower part 4 and the part of the upper body part 2b where the locking protrusion 8 is provided are deformed such that the regulating part 12 is deformed, and the locking protrusion 8 is not engaged. It is possible to prevent a situation where the stopped state is canceled. In addition, since the restricting portion 12 of the lower part 4 fits inside the upper part 5 when the cone 1 is connected, force is applied from the side to the upper main body 2b when the cone 1 is connected. Even if the locking projection 8 and the locking hole 13 are locked, it is possible to avoid a situation where the upper body portion 2b is deformed to the side where the locking state between the locking projection 8 and the locking hole 13 is released.

The height of the upper part 5 is approximately the same as the height of the lower part 4 to the upper surface of the receiving part 11. Therefore, the effect of storing the upper parts assembly 9 inside the lower parts assembly 26 and improving the transportation efficiency is further achieved.

Further, in the regulating portion 12 , a peripheral portion of the locking hole 13 is a thick portion 15 that is thicker than the general portion 14 of the regulating portion 12 . Therefore, the rigidity of the peripheral edge of the locking hole 13 can be increased to make it difficult to deform, and as a result, the locked state of the locking protrusion 8 can be stabilized. Further, since the thick part 15 is configured by making the thickness of the regulating part 12 thicker outward than the general part 14, the regulating part 12 is formed in the upper body of the upper part 5 in the thick part 15. It comes into contact with the inner surface of the portion 2b. Therefore, for example, when connecting the upper part 5 and the lower part 4, compared to the case where the entire outer surface of the regulating part 12 contacts the inner surface of the upper body part 2b of the upper part 5 (slidingly contacts during the connecting operation), , it becomes easier to insert the restriction part 12 inside the upper body part 2b by reducing friction, and it is possible to improve the connection workability.

In addition, since the lower part 4 and the upper part 5 are configured as separate parts, the coloring and material can be selected for each of the lower part 4 and the upper part 5, which improves convenience, etc. can be achieved. That is, in this embodiment, the upper part 5 and the lower part 4 are colored differently, making it easier to recognize that the upper parts assembly 9 is inserted inside the lower parts assembly 26. . Furthermore, it is possible to diversify the visibility mode, and the visibility mode can be greatly changed by simply replacing the upper part 5 and the lower part 4 without changing the other, and replacement is also easy. Is possible. Therefore, for example, the lower part 4 is of one common type, but there are multiple types of upper parts 5 in different colors, and the upper part 5 can be selected as appropriate depending on the purpose. Improvements can be made.

Further, when the lower parts 4 are stacked on top of each other, the lower edge of the lower stacking rib 25 of the upper lower part 4 is supported by coming into contact with the upper surface of the horizontally extending part 21 of the lower lower part 4. It is configured to For this reason, for example, compared to a configuration in which the vertical positioning of the lower parts 4 stacked vertically is performed by bringing the upper lower part 4 into pressure contact with the outer surface of the lower lower part 4, the lower parts assembly Variations in the height of the lower parts assembly 26 can be suppressed while preventing the body 26 from tilting. Further, when the upper parts 5 are stacked on top of each other, the lower edge of the upper stacking rib 7 of the upper upper part 5 comes into contact with the upper end of the upper body part 2b of the lower upper part 5 and is supported. It is configured as follows. For this reason, for example, by bringing all the locking protrusions 8 of the upper part 5 on the upper side into pressure contact with the outer surface of the upper body part 2b of the upper part 5 on the lower side, the upper parts 5 stacked vertically can be Compared to a configuration in which directional positioning is performed, it is possible to prevent the upper parts assembly 9 from tilting, suppress variations in the height of the upper parts assembly 9, and protect the locking protrusion 8. It has become.

Therefore, while stabilizing the postures of the lower parts assembly 26 and the upper parts assembly 9, the amount of increase in height when stacking the lower parts 4 on the lower parts 4, and the increase in height of the upper parts 5. On the other hand, the amount of increase in height when the upper parts 5 are stacked can be kept constant. This makes it possible to avoid a situation where, for example, the upper parts assembly 9 is tilted and the workability is reduced when stacking the lower parts assembly 26. Further, for example, variations in the height of the upper parts assembly 9 and the height of the lower parts assembly 26 become large, and the upper parts assembly 9 protrudes upward from the upper opening of the lower parts assembly 26, or To more reliably avoid a situation where the upper parts assembly 9 comes into contact with the lower parts assembly 26 and a part of the lower parts 4 constituting the lower parts assembly 26 is lifted by the upper parts assembly 9. Can be done.

Note that the present invention is not limited to the content described in the above embodiment, and may be implemented as follows, for example. Of course, other applications and modifications not exemplified below are also possible.

(a) As shown in FIG. 8, a thick portion of the regulating portion 12 between the locking hole 13 and the upper edge of the restricting portion 12 and adjacent to the upper edge of the locking hole 13 The portion located above the thick wall portion 15 may be a thin wall portion 31 that is thinner than the thick wall portion 15 and whose outer surface is one step lower than the outer surface of the thick wall portion 15 toward the inner side of the lower body portion 2a. In this case, when connecting the upper part 5 and the lower part 4, it becomes easier to insert the locking protrusion 8 into the locking hole 13, and it is possible to improve the connection workability. In addition, it is also possible to make the thickness constant in any part of the regulating part 12. Note that, on both sides of the thin wall portion 31, thick wall portions 15 are provided so as to extend to the upper edge of the regulating portion 12.

(b) In the above embodiment, the receiving portion 11 is configured by the upper edge of the lower body portion 2a, but the receiving portion is configured by a rib projecting outward from the upper edge of the lower body portion 2a, and the receiving portion 11 is configured by the upper edge of the lower body portion 2a. The lower edge of the upper main body portion 2b may be configured to abut on the upper surface of the receiving portion. When adopting this configuration, the restriction portion is provided by extending the lower body portion 2a upward as it is.

Further, when the lower parts 4 are stacked on top of each other, the lower edge of the lower stacking rib 25 of the upper lower part 4 is supported by coming into contact with the upper surface of the horizontally extending part 21 of the lower lower part 4. However, the configuration for supporting the lower parts 4 at the same height position without inclination is not particularly limited. For example, the vertical width of the vertically extending portion 22 The supporting rib 27 (and reinforcing rib 28) of the upper lower part 4 is configured to be in contact with and supported by the upper surface of the base plate part 23 of the lower lower part 4, etc. , can be changed as appropriate. Note that the configuration of the pedestal part 3 is not particularly limited; for example, it may have a shape in which the horizontally extending part 21 and the vertically extending part 22 are omitted, or it may have a shape in which the base plate part 23 and the bottom part 24 are omitted. It is also possible to make it into a shape.

(c) In the above embodiment, the upper part 5 is provided with the locking protrusion 8, and the regulating protrusion 8 is inserted into the locking hole 13 provided in the lower part 4, so that the upper part 5 and the lower part 4, but a different configuration (for example, a regulating protrusion is provided on the outer surface side of the regulating part 12 of the lower part 4, a locking hole is provided in the upper body part 2b of the upper part, or They may be configured to be connected by providing a locking recess, etc.). Furthermore, in the above embodiment, the length of the locking protrusion 8 protruding from the upper body portion 2b is configured to be longer than the thickness of the regulating portion 12 (thick wall portion 15); The thickness of the part 12 (thick part 15) is (approximately) the same (in the connected state of the cone 1, the locking protrusion 8 is not protruded inward from the inner surface of the upper body part 2b). ) may be configured.

Further, in the above embodiment, when the upper parts 5 are stacked together, the lower edge of the upper stacking rib 7 of the upper upper part 5 comes into contact with the upper end of the upper body part 2b of the lower upper part 5. Although the upper parts 5 are configured to be supported in contact with each other, the configuration for supporting the upper parts 5 at the same height position without inclination is not particularly limited, and can be modified as appropriate.

In the above embodiment, a (substantially circular) through hole may be provided at the upper end portion of the upper body portion 2b to vertically penetrate the upper body portion 2b. In this case, when taking out the uppermost parts 5 one by one from a stack of upper parts 5, it is important to note that negative pressure will develop between the uppermost part 5 and the upper part 5 below it. At the same time, it becomes possible to lift the uppermost part 5 by placing a fingertip on the back side of the upper part 5 through the through hole.

(d) In the above embodiment, the upper part 5 and the lower part 4 are made of low-density polyethylene, but they can be appropriately changed to other resin materials such as high-density polyethylene or polypropylene. Furthermore, in the above embodiment, the material of the upper part 5 and the material of the lower part 4 may be made different. In this case, the materials of the upper part 5 and the lower part 4 can be selected in accordance with the required functions. For example, the lower part 4, which often comes into contact with workers' feet, wheels, etc., is made of a relatively soft resin to prevent damage, while the upper part 5 is made of a relatively hard resin. For example, compared to a case in which the upper part 5 is also made of soft resin, the construction is such that the connection work with the lower part 4 (the work of inserting the regulating part 12 inside the upper main body part 2b) is relatively smooth. Can be adopted. In addition, by making (at least a part of) one of the upper part 5 and the lower part 4 transparent resin, it is possible to reduce the cost compared to the case where the entire part is made of transparent resin, and to make the inside of the cone 1 This makes it easier to discover that a suspicious object is installed.

Further, in the above embodiment, the coloring of the upper part 5 and the coloring of the lower part 4 are configured to be different, but it is also possible to color them the same. Furthermore, in the above embodiment, the entire upper part assembly 9 made up of a maximum of 10 upper parts 5 can be accommodated inside the lower part 4 made up of the same number (10) of lower parts 4. However, it is not particularly limited to such a configuration, and the entire upper part assembly 9 consisting of a specific number, with a plurality other than 10 as the upper limit, is the lower part 4 consisting of the same number of lower parts 4. It may be configured so that it can be accommodated inside the.
