Description

[Technical field]

[0001] The present invention relates to a road cone. [Background technology]

[0002] A road cone has been proposed that allows a safety light to be installed at the top, makes it difficult for the safety light to come off once installed, and is easy to lift and move regardless of whether a safety light is installed or not (see Patent Document 1). According to this road cone, a safety light installation section where a safety light is installed is provided at the upper end of the cone body, which is formed in a cylindrical shape with a diameter that gradually decreases from bottom to top, and finger hooks are formed on both sides of the outer wall of the upper end of the cone body.

[0003] [Patent Document 1] JP 2023-081556 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the finger hook is formed by a ring-shaped recess formed on the outer wall of the upper end of the cone body, and the ring-shaped recess may be shallow and unable to hook the finger sufficiently. Also, when a worker moves a road cone, he or she approaches the cone body in an arc shape with the thumb and middle finger (or index finger) looped around the recess, and so in their haste to complete the work, they tend to grab the safety light installed on the upper end of the cone body by looping their thumb and middle finger around it with the hand in that position.

[0005] Therefore, an object of the present invention is to provide a road cone that is easy for a worker to hold and reduces the possibility that the worker will grab the safety light attached to the top. [Means for solving the problem]

[0006] The road cone of the present invention is A road cone having a main body formed in a cylindrical shape, The upper end of the main body is configured so that a safety light can be attached to the upper end opening in a removable manner, A first opening for inserting fingers is formed in an upper side wall of the main body and extends in a circumferential direction.

[0007] With this type of road cone, a worker approaches the main body with his or her hand open and palm facing up in order to insert his or her middle finger or other finger from the outside of the main body into the inside through the first opening, and so must change the position of his or her fingers in order to grab the safety light attached to the top. This reduces the possibility that the worker will grab the safety light during the process of moving the road cone. Then, with the worker's middle finger or other finger hooked on the main body at the first opening, the main body, and therefore the road cone, can be easily lifted and moved with one hand.

[0008] In the road cone having the above configuration, A second opening for inserting a finger is formed in an upper side wall of the main body, the second opening being spaced apart from the first opening at least either above or below the first opening. It is preferred.

[0009] With a road cone of this configuration, a worker can more easily lift and move the road cone with one hand by hooking one or more first fingers (e.g., middle finger, etc.) onto the main body part at the first opening, and one or more second fingers (e.g., thumb, etc.) onto the main body part at the second opening.

[0010] In the road cone having the above configuration, A recess is formed in an upper side wall of the main body, the recess being spaced apart from the first opening at least one side above and below the first opening and extending along a circumferential direction, and the second opening is formed in the recess. It is preferred.

[0011] With a road cone of this configuration, the freedom to hook one or more second fingers (e.g., the thumb) onto the main body at the recess or second opening is improved, making it easier to lift and move the road cone with one hand. [Brief description of the drawings]

[0012] [Figure 1] 1 is a perspective view of a road cone according to an embodiment of the present invention; [Diagram 2] 1 is a cross-sectional view of a road cone according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] (composition) A road cone 10 according to an embodiment of the present invention shown in FIG. 1 includes a main body 11 and a base 12. The road cone 10 is installed on the ground, such as a road or a construction site, and is used. As shown in FIG. 1, the main body 11 is formed, for example, in a substantially truncated cone shape having an upper end opening 100. The main body 11 has an upper end opening 102 formed in a substantially cylindrical side surface shape, and a key groove 102 extending in the axial direction is formed therein. The main body 11 may be formed in a cylindrical shape, such as a substantially truncated pyramid shape, in which the diameter or cross-sectional area decreases continuously or intermittently from the lower end to the upper end. The base 12 is formed in a substantially rectangular or square shape in a plan view, is formed continuously with the lower end of the main body 11, and supports the main body 11.

[0014] 2 (a cross section passing through the central axis of the upper part of the road cone 10), the base 22 of the safety light 20 is inserted into the upper end of the main body 11, and thus the upper end of the road cone 10, and the safety light 22 is removably attached with its light-emitting part 21 (having a light-emitting body such as an LED) exposed to the outside. The base 22 of the safety light 20 has a substantially cylindrical outer shape that fits the shape of the upper opening 100 of the main body 11. The base 22 is provided with a protrusion 222 that protrudes in the radial direction.

[0015] The base 22 is inserted into or through the upper end opening 102 after its projection 222 is aligned with the key groove 102 of the upper end opening 100 of the road cone 10. Then, the safety light 20 is rotated about its axis so that the positions or phases of the projection 222 and the key groove 102 are shifted. This causes the upper end of the projection 222 to abut against the side wall of the main body 11 that defines the upper end opening 100, preventing the safety light 20 from slipping out of the upper end opening 102 and falling off the main body 11.

[0016] As shown in FIG. 1 and FIG. 2, an opening 110 (slit) extending in the circumferential direction is formed in the upper side wall of the main body 11. The width (vertical size) and length (circumferential or horizontal size) of the opening 110 are designed so that at least one (e.g., two to four) of a standard human finger can be inserted therein. The circumferential range (or phase range) in which the opening 110 is provided in the main body 11 is designed to include, for example, the circumferential range in which the key groove 102 is provided in the main body 11. The opening 110 extends in an approximately arc shape with a central angle of, for example, 10° to 30° in the upper outer wall of the main body 11. The number of openings 110 may not be "1" but may be multiple. The multiple openings 110 may be arranged so as to be intermittently lined up in the circumferential direction of the main body 11 at the same height position, or the multiple openings 110 may be arranged so as to have different heights from each other.

[0017] As shown in Figs. 1 and 2, a first recess 111 is formed in the upper side wall of the main body 11, extending in the circumferential direction above the opening 110. The first recess 111 may extend in an annular shape around the entire circumference of the main body 11, and may extend in an approximately arc shape with a central angle of 20° to 300°, for example. The width, length and depth of the first recess 111 are designed so that at least one finger (for example, one finger) of a standard human finger can be hooked therein. The distance between the first recess 111 and the opening 110 is designed so that, for example, when the index finger and / or middle finger are inserted into the opening 110, the thumb can be hooked in the first recess 111.

[0018] As shown in Figs. 1 and 2, a second recess 112 is formed in the upper side wall of the main body 11 below the opening 110 and extends in the circumferential direction. The second recess 112 may extend in an annular shape around the entire circumference of the main body 11, and may extend in an approximately arc shape with a central angle of 20° to 300°, for example. The width, length and depth of the second recess 112 are designed so that at least one finger (for example, two to four fingers) of a standard human finger can be hooked therein. The distance between the second recess 112 and the opening 110 is designed so that, for example, when the thumb is inserted into the opening 110, the index finger and / or middle finger can be hooked in the first recess 111.

[0019] The first recess 111 and / or the second recess 112 may be omitted.

[0020] (Action and effect) According to the road cone 10 having this configuration, a worker approaches the main body 11 with his / her hand open and palm facing up in order to insert his / her middle finger or the like from the outside of the main body 11 into the inside through the opening 110, so that the worker needs to change the position of his / her fingers in order to grab the safety light 20 attached to the top or upper end. This reduces the possibility that the worker will grab the safety light 20 during the process of moving the road cone 10. Then, with the middle finger or the like of the hand hooked on the main body 11 at the opening 110, the worker can easily lift and move the main body 11, and thus the road cone 10, with one hand.

[0021] Furthermore, the worker can lift and move the road cone 10 more easily with one hand by hooking one or more first fingers (e.g., index finger and / or middle finger, etc.) on the main body 11 at the opening 110 and hooking one or more second fingers (e.g., thumb, etc.) on the main body 11 at the first recess 111. The worker can lift and move the road cone 10 more easily with one hand by hooking one or more first fingers (e.g., thumb, etc.) on the main body 11 at the opening 110 and hooking one or more second fingers (e.g., index finger and / or middle finger, etc.) on the main body 11 at the second recess 112.

[0022] Since the first recess 111 and the second recess 112 are each formed to extend circumferentially, the freedom to hook one or more second fingers (e.g., the thumb, etc.) onto the main body portion 11 at the first recess 111 and / or the second recess 112 is improved, making it easier to lift and move the road cone 10 with one hand.

[0023] 2, in the main body 11, the opening 110 is formed at a position lower than the lower end of the base 22 of the safety light 20 attached to the upper end of the main body 11. Therefore, it is possible to prevent a situation in which fingers that enter the internal space of the main body 11 through the opening 110 interfere with the base 22.

[0024] (Another embodiment of the present invention) In the main body 11, the opening 110 may be formed at a position higher than the lower end of the base 22 of the safety light 20 attached to the upper end of the main body 11. The circumferential range (or phase range) in which the opening 110 is provided in the main body 11 is designed to include, for example, the circumferential range in which the key groove 102 is provided in the main body 11. As a result, when the base 22 of the safety light 20 is attached to the main body 10, the circumferential position of the protrusion 222 of the base 22 is out of the circumferential range of the opening 110. Therefore, it is possible to prevent a situation in which a finger entering the internal space of the main body 11 through the opening 110 interferes with the protrusion 222.

[0025] A second opening may be formed in the first recess 111 and / or the second recess 112, which is locally present or extends in the circumferential direction of the main body portion 11 and penetrates the upper outer wall of the main body portion 11. [Explanation of symbols]
