Japanese Unexamined Patent Publication No. 2014-2006

By the way, when the cone of Patent Document 1 is stored 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 contracted, the three or more parts constituting the cone are completely separated. For this reason, when transporting and storing a plurality of corns together, the corns in the contracted state cannot be simply stacked, and the corns in the contracted state are packed and then stacked or stacked. , It is conceivable to extend the cones and stack the cone parts in a state of being connected to each other. Here, it is required to improve the transportation efficiency and the storage efficiency of the corn when it is not used.

The present invention has been made to solve the above-exemplified problems and the like, and an object of the present invention is to provide a cone capable of improving transportation efficiency and storage efficiency when not in use. be.

Hereinafter, each means suitable for solving the above-mentioned problems and the like will be described separately for each item. In addition, if necessary, the action and effect peculiar to the corresponding means will be added.

Means 1. In a cone having a main body having a substantially conical outer shape,
The cone
A lower part having a lower main body, which is a lower part of the main body,
It includes an upper main body, which is an upper part of the main body, and is composed of an upper part that is detachably provided with respect to the upper part of the lower part.
In a separated state in which the cone is separated into the lower part and the upper part, the upper part can be accommodated inside the lower part.
The upper part is provided with a locking projection protruding from the inner surface of the upper main body portion.
The lower part is
In a connected state in which the lower part and the upper part are connected, a receiving portion that comes into contact with the lower edge portion of the upper main body portion and supports the upper part.
In the connected state, a regulating portion that substantially abuts on the inner surface of the upper main body portion is provided.
The regulating portion is provided with a locking hole that penetrates in the inner and outer directions of the lower main body portion.
In the connected state, the locking projection of the upper part is inserted into the locking hole, and the locking projection and the peripheral edge portion of the locking hole are substantially locked. ..

According to the means 1, by separating the cone into a lower part and an upper part and accommodating the upper part inside the lower part, it is possible to compactly organize the cone when not in use. Further, by stacking the upper parts and stacking the lower parts so as to surround the upper parts, it is possible to compactly combine a plurality of cones. Therefore, it is possible to improve the transportation efficiency and the storage efficiency when not in use.

In addition, the lower part is provided with a receiving part that abuts and supports the lower edge of the upper main body of the upper part in the connected state of the cone that connects the lower part and the upper part, and faces downward with respect to the upper part. When the force of is applied, the downward displacement of the upper part can be effectively regulated. Further, the lower part is provided with a restricting portion that substantially contacts the inner surface of the upper main body of the upper part in the connected state of the cone, and the upper part is in the horizontal direction with respect to the lower part in the connected state of the cone. It is possible to prevent a situation in which the material is displaced relative to each other and falls off. In particular, since the regulation part of the lower part fits inside the upper body part, it is possible to avoid the situation where the upper part falls off to the inner side of the lower part, and the cone is used as a connected state. It is 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 part of the cone in the connected state (for example, the cone bar is provided so as to hang between the upper parts of the pair of cones), the cone The connected state (usage mode) can be reliably maintained, and the function of installing the cone on the road surface or the like to teach the passerby predetermined information can be reliably exerted.

Further, the upper part is provided with a locking projection protruding from the inner surface of the upper main body portion, and the regulating portion of the lower part penetrates in the inner and outer directions of the lower main body portion to be in a locked state with the locking projection. A locking hole is provided. For this reason, for example, as compared with a configuration in which the locking projection is locked in a recess that fits in the thickness of the regulating portion instead of the locking hole penetrating the regulating portion, the locking projection can be formed without making the regulating portion 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 only by inserting the regulating portion of the lower part inside the upper main body portion of the upper part and inserting the locking projection 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 portion of the upper part and the lower part). It is possible to improve the connection workability as compared with (for example, screwing the upper edge portion).

In addition, it is possible to prevent the locking holes and the locking projections from being exposed to the outer surface side of the cone in the connected state of the cone. Therefore, it is possible to suppress the formation of a step portion or a recess on the outer surface side of the main body portion of the cone in the connected state, and another object is caught on the step portion or the recess, dust or the like is accumulated on the step portion or the recess. It is possible to improve the design of the cone while avoiding such situations.

Further, as described above, since the lower part is provided with the receiving portion and the regulating portion, even if a downward force is applied to the upper part in the connected state of the cone, the locking projection and the engaging portion are engaged. It is possible to avoid applying a relatively large load to the peripheral portion of the stop hole. Therefore, deterioration or damage of the locking projection and the peripheral portion of the locking hole can be suppressed, and as a result, durability can be improved.

Further, a receiving portion is provided between the lower main body portion and the regulating portion. For example, even if a force is applied from the side to the lower main body portion and the lower main body portion is slightly deformed, the lower main body portion may be deformed. It is possible to make it difficult for the deformation to spread to the regulation part. Therefore, for example, the regulating portion of the lower part is deformed so that the portion of the upper main body where the locking projection is provided is separated from each other, and the locking state of the locking projection is released. Such a situation can be prevented. In addition, since the regulation part of the lower part fits inside the upper part in the connected state of the cone, even if a force is applied from the side to the upper main body part in the connected state of the cone, it is engaged. It is possible to avoid a situation in which the upper main body is deformed to the side where the locked state of the stop protrusion and the locking hole is released.

It should be noted 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 portion (and lower than the height of the lower part)". In this case, the effect of accommodating the upper part inside the lower part to improve the transportation efficiency and the like is further achieved.

Means 2. The cone according to means 1, wherein the peripheral edge portion of the locking hole among the restricting portions is a thick portion thicker than a general portion which is another portion of the restricting portion.

According to the means 2, the rigidity of the peripheral portion of the locking hole can be increased to make it difficult to deform, and as a result, the locked state of the locking projection can be stabilized. Further, when the thick portion is formed by making the thickness of the regulation portion outward as compared with the general portion, the regulation portion shall come into contact with the inner surface of the upper main body portion of the upper part in the thick portion. It becomes. Therefore, for example, as compared with the case where the entire outer surface of the regulating portion abuts on the inner surface of the upper main body portion of the upper part, the regulating portion is inserted inside the upper main body portion when connecting the upper part and the lower part. It becomes easier and the connection workability can be improved.

Means 3. Of the restricting portions, a portion between the locking hole and the upper edge portion of the restricting portion and located above the thick-walled portion adjacent to the upper edge portion of the locking hole is an outer surface. 2. The cone according to means 2, wherein is configured to be one step lower on the inner side of the lower main body portion than on the outer surface of the thick portion.

According to the means 3, when connecting the upper part and the lower part, the locking projection can be easily inserted into the locking hole, and the connecting workability can be improved.

Means 4. In a cone having a main body having a substantially conical outer shape,
The cone
A lower part having a lower main body, which is a lower part of the main body,
It includes an upper main body, which is an upper part of the main body, and is composed of an upper part that is detachably provided with respect to the upper part of the lower part.
At least one of the coloring and the material is different between the lower part and the upper part.
A plurality of the cones composed of a specific number are separated into the lower part and the upper part, and the separated upper parts assembly composed of the specific number of the upper parts are stacked one above the other. When a lower part assembly in which a plurality of the lower parts composed of the specific number separated are stacked one above the other is arranged so as to surround the upper part assembly, the entire upper part assembly is the lower part assembly. A cone characterized by being configured to be housed inside the body.

According to the means 4, a set of upper parts in which a plurality of separated upper parts are stacked one above the other, and a set of lower parts in which a plurality of separated lower parts are stacked one above the other. By arranging the body so as to surround the upper part assembly, it is possible to compactly combine a plurality of cones consisting of a specific number. Therefore, it is possible to improve the transportation efficiency and the storage efficiency when not in use.

Further, the lower part and the upper part can be colored and the material can be selected, respectively, and the convenience can be improved. That is, for example, by making the coloring different between the upper part and the lower part, it is possible to easily recognize that the upper part assembly is inserted inside the lower part assembly. Further, the visual mode can be diversified, and the visual mode can be significantly changed by simply replacing one of the upper part and the lower part without replacing the other, and the replacement can be easily performed. It is possible. Therefore, for example, the lower part is one type in common, but there are multiple types of upper parts in different colors, and the upper part is appropriately selected according to the application. Can be planned.

In addition, for example, by making the upper part and the lower part different materials, it is possible to select a material suitable for each required function. For example, the lower part, which has many opportunities to come into contact with the worker's feet and wheels, is made of a relatively soft resin to prevent damage, and the upper part is made of a relatively hard resin, for example. Compared with the case where the upper part is also made of soft resin, it is possible to adopt a configuration in which the connection work with the lower part (the work of inserting the regulation portion inside the upper main body portion) is relatively smooth. In addition, by using transparent resin for one (at least a part of) the upper part and the lower part, suspicious objects can be found inside the cone while reducing costs compared to the case where the entire part is made of transparent resin. It is possible to make it easier to discover that it is installed.

In addition, "the entire upper part assembly is housed inside the lower part set" means that a plurality of upper part sets consisting of a specific number are housed inside a plurality of lower part sets composed of a specific number. However, the upper part assembly and the lower part assembly can be grounded to the installation surface without bringing the upper part assembly and the lower part assembly into contact with each other, and the upper part assembly can be grounded. Is intended not to project upwards from the lower parts assembly. Further, the technical ideas of the above means 1 to 3 may be combined with the means 4.

It is a perspective view which shows the cone. It is an exploded perspective view of a cone. It is a perspective view including a partial cross section of a cone. It is a partially enlarged perspective view including a partial cross section which shows the connecting part between the upper part and the lower part. It is a partially enlarged perspective view including a partial cross section which shows the connecting part between the upper part and the lower part. It is sectional drawing which shows the state in which the cones are stacked. It is sectional drawing which shows the state which housed the upper part assembly inside the lower part assembly.

Further, the lower part 4 includes a receiving portion 11 that abuts and supports the lower edge portion of the upper main body portion 2b of the upper part 5 in the connected state of the cone 1 that connects 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 regulated. Further, the lower part 4 is provided with a restricting portion 12 that substantially contacts the inner surface of the upper main body portion 2b of the upper part 5 in the connected state of the cone 1, and the upper part 5 is lowered in the connected state of the cone 1. It is possible to prevent a situation in which the parts 4 are displaced relative to each other in the horizontal direction and fall off. In particular, since the regulating portion 12 of the lower part 4 is fitted inside the upper main body portion 2b, it is possible to avoid a situation in which the upper part 5 falls off to the inward side of the lower part 4, and the cone 1 can be used. It is possible to more reliably prevent a situation in which the cone 1 is inadvertently separated during use as 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, the cone bar is provided so as to span between the upper part 5 of the pair of cones 1). ), The connected state (usage mode) of the cone 1 can be reliably maintained, and the function of installing the cone 1 on the road surface or the like and teaching predetermined information to passersby can be reliably exerted.

A locking hole 13 is provided so as to be in a locked state. Therefore, for example, the regulation portion 12 is made thicker than the configuration in which the locking projection 8 is locked in the recess that fits in the thickness of the regulation portion 12 instead of the locking hole 13 that penetrates the regulation portion 12. The protruding length of the locking projection 8 can be made as large as possible, and the locked state can be stabilized.

Further, the upper part 5 and the lower part 4 can be connected only by inserting the regulating portion 12 of the lower part 4 inside the upper main body portion 2b of the upper part 5 and inserting the locking projection 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). It is possible to improve the connection workability as compared with (for example, screwing the portion and the upper edge portion of the lower part 4).

In addition, it is possible to prevent the locking hole 13 and the locking projection 8 from being exposed to the outer surface side of the cone 1 in the connected state of the cone 1. Therefore, it is possible to suppress the formation of a step portion or a recess on the outer surface side of the main body portion 2 of the cone 1 in the connected state, and another object is caught on the step portion or the recess, dust or the like is generated. It is possible to improve the design of the cone 1 while avoiding a situation such as accumulation.

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

Further, a receiving portion 11 is provided between the lower main body portion 2a and the regulating portion 12, and for example, a force is applied from the side to the lower main body portion 2a to slightly deform the lower main body portion 2a. Even if it does, it is possible to make it difficult for the deformation to spread to the regulation unit 12. Therefore, for example, the regulating portion 12 of the lower part 4 is deformed so as to be separated from the portion of the upper main body portion 2b where the locking projection 8 is provided, and the locking projection 8 is engaged. It is possible to prevent a situation in which the stopped state is released. In addition, since the regulating portion 12 of the lower part 4 is fitted inside the upper part 5 in the connected state of the cone 1, a force is applied from the side to the upper main body portion 2b in the connected state of the cone 1. Even if this is done, it is possible to avoid a situation in which the upper main body portion 2b is deformed to the side where the locking state of the locking projection 8 and the locking hole 13 is released.

The height of the upper part 5 is substantially the same as the height of the lower part 4 to the upper surface of the receiving portion 11. Therefore, the effect of accommodating the upper part assembly 9 inside the lower part assembly 26 to improve the transportation efficiency and the like is further achieved.

Further, among the regulating portions 12, the peripheral portion of the locking hole 13 is a thick portion 15 which is thicker than the general portion 14 of the regulating portion 12. Therefore, the rigidity of the peripheral portion of the locking hole 13 can be increased to make it difficult to deform, and as a result, the locked state of the locking projection 8 can be stabilized. Further, since the thick portion 15 is formed by making the thickness of the regulation portion 12 outward as compared with the general portion 14, the regulation portion 12 is the upper main body of the upper part 5 in the thick portion 15. It will come into contact with the inner surface of the portion 2b. Therefore, for example, when the upper part 5 and the lower part 4 are connected, as compared with the case where the entire outer surface of the regulating portion 12 comes into contact with the inner surface of the upper main body portion 2b of the upper part 5 (sliding contact during the connecting work). , Friction is reduced, the regulating portion 12 can be easily inserted into the upper main body portion 2b, and the connection workability can be improved.

Further, since the lower part 4 and the upper part 5 are configured as separate parts, the lower part 4 and the upper part 5 can be colored and the material can be selected respectively, which improves convenience and the like. Can be planned. That is, in the present embodiment, the coloring is different between the upper part 5 and the lower part 4, and it is possible to easily recognize that the upper part assembly 9 is inserted inside the lower part assembly 26. .. Further, the visual mode can be diversified, and the visual mode can be significantly changed by simply replacing one of the upper part 5 and the lower part 4 without replacing the other, and the replacement can be easily performed. It is possible. Therefore, for example, the lower part 4 is one type in common, but the upper part 5 has a plurality of types in different colors, and the upper part 5 is appropriately selected according to the application. It can be improved.

Further, when the lower parts 4 are stacked, the lower edge portion of the lower stacking rib 25 of the upper lower part 4 abuts on the upper surface of the laterally extending portion 21 of the lower lower part 4 and is supported. It is configured to. Therefore, for example, as compared with a configuration in which the lower parts 4 on the upper side and the outer surface of the lower parts 4 on the lower side are pressed against each other to position the lower parts 4 stacked vertically in the vertical direction, the lower parts are assembled. While preventing the body 26 from tilting, it is possible to suppress variations in the height of the lower parts assembly 26. Further, when the upper parts 5 are stacked, the lower edge portion of the upper stacking rib 7 of the upper upper part 5 abuts on the upper end portion of the upper main body portion 2b of the lower upper part 5 and is supported. It is configured as follows. Therefore, for example, by pressing all the locking projections 8 of the upper upper part 5 and the outer surface of the upper main body 2b of the lower upper part 5, the upper and lower parts 5 stacked one above the other are vertically contacted. Compared to the configuration in which the direction is positioned, the upper parts assembly 9 can be prevented from tilting, the height variation of the upper parts assembly 9 can be suppressed, and the locking projection 8 can be protected. It has become.

Therefore, while stabilizing the postures of the lower part assembly 26 and the upper part assembly 9, the amount of increase in height when the lower part 4 is stacked on the lower part 4 and the upper part 5 On the other hand, the amount of increase in height when the upper parts 5 are stacked can be made constant. Thereby, for example, it is possible to avoid a situation in which the upper parts assembly 9 is tilted, which causes a decrease in workability when stacking the lower parts assembly 26. Further, for example, the height of the upper part assembly 9 and the height of the lower part assembly 26 vary greatly, and the upper part assembly 9 protrudes upward from the opening at the upper part of the lower part assembly 26, or To more reliably avoid a situation in which the upper part assembly 9 comes into contact with the lower part assembly 26 and a part of the lower part 4 constituting the lower part assembly 26 is lifted by the upper part assembly 9. Can be done.

The content is not limited to the description of the above embodiment, and may be implemented as follows, for example. Of course, other application examples and modification examples not illustrated 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 portion of the regulating portion 12 and adjacent to the upper edge portion of the locking hole 13. The portion located above the thick portion 15 may be a thin portion 31 which is thinner than the thick portion 15 and whose outer surface is one step lower than the outer surface of the thick portion 15 on the inner side of the lower main body portion 2a. In this case, when connecting the upper part 5 and the lower part 4, the locking projection 8 can be easily inserted into the locking hole 13, and the connecting workability can be improved. It is also possible to keep the thickness constant at any part of the regulation unit 12. On both sides of the thin portion 31, the thick portion 15 is provided so as to extend to the upper edge portion of the regulation portion 12.

(B) In the above embodiment, the receiving portion 11 is formed by the upper edge portion of the lower main body portion 2a, but the receiving portion is formed by ribs protruding outward from the upper edge portion of the lower main body portion 2a. The lower edge portion of the upper main body portion 2b may be in contact with the upper surface of the receiving portion. When this configuration is adopted, the regulating portion is provided by extending the lower main body portion 2a as it is upward.

Further, when the lower parts 4 are stacked, the lower edge portion of the lower stacking rib 25 of the upper lower part 4 abuts on the upper surface of the laterally extending portion 21 of the lower lower part 4 and is supported. However, the configuration for supporting the lower parts 4 at the same height position without tilting is not particularly limited. For example, the vertical width of the vertically extending portion 22 is the hem portion. It is shorter than the vertical width of 24, and the support rib 27 (and the 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 portion 23 of the lower lower part 4. , Can be changed as appropriate. The configuration of the pedestal portion 3 is not particularly limited, and for example, the shape may be such that the laterally extending portion 21 and the vertically extending portion 22 are omitted, or the base plate portion 23 and the hem portion 24 are omitted. It is also possible to make it into a different shape.

(C) In the above embodiment, the upper part 5 is provided with the locking projection 8, and the regulation protrusion 8 is inserted into the locking hole 13 provided in the lower part 4, whereby the upper part 5 and the lower part are inserted. Although it is configured to be connected to 4, another configuration (for example, a regulating protrusion is provided on the outer surface side of the regulating portion 12 of the lower part 4 and a locking hole or a locking hole or a locking hole or the upper main body portion 2b of the upper part is provided. It may be configured to be connected by providing a locking recess, etc.). Further, in the above embodiment, the protruding length of the locking projection 8 from the upper main body portion 2b is longer than the thickness of the regulating portion 12 (thick wall portion 15), but the protruding length of the locking projection 8 is restricted. Make sure that the thickness of the portion 12 (thick portion 15) is (almost) the same (in the connected state of the cone 1, the locking projection 8 does not protrude inward from the inner surface of the upper main body portion 2b). ) May be configured.

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

In the above embodiment, the upper end portion of the upper main body portion 2b may be provided with a (substantially circular) through hole that penetrates the upper main body portion 2b up and down. In this case, when the upper parts 5 on the uppermost stage are taken out one by one from the state where the upper parts 5 are stacked, a negative pressure is generated between the upper parts 5 on the uppermost stage and the upper parts 5 below the upper parts 5. While avoiding it, it is possible to lift the uppermost part 5 by hanging a fingertip on the back surface 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 can be appropriately changed to another resin material such as high-density polyethylene or polypropylene. Further, in the above embodiment, the material of the upper part 5 and the material of the lower part 4 may be different. In this case, a material suitable for each of the required functions of the upper part 5 and the lower part 4 can be selected. For example, the lower part 4, which has many opportunities to come into contact with the feet and wheels of the worker, is made of a relatively soft resin to prevent damage, and the upper part 5 is made of a relatively hard resin. For example, as compared with the case where the upper part 5 is also made of soft resin, the connection work with the lower part 4 (the work of inserting the regulation portion 12 inside the upper main body portion 2b) is made relatively smooth. Can be adopted. Further, by using transparent resin for one (at least a part) of the upper part 5 and the lower part 4, the inside of the cone 1 can be reduced in cost as compared with the case where the whole is made of transparent resin. It is possible to easily find 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 the same coloring is also possible. Further, in the above embodiment, the entire upper part assembly 9 composed of a maximum of 10 upper parts 5 can be accommodated inside the lower part 4 composed of the same number (10 pieces) of lower parts 4. However, the configuration is not particularly limited to this, and the entire plurality of upper part aggregates 9 composed of a specific number may be the entire lower part 4 composed of the same number of lower parts 4 up to a plurality of parts other than 10. It may be configured to be accommodated inside the.
