As shown in FIG. 2, the grip 10 of the present invention includes a ring member 11, and has a configuration in which a locking projection 12 is formed on the outer peripheral surface 11 a of the ring member 11.
The ring member 11 has a taper shape having the same taper angle as the outer peripheral surface 4a of the upper end portion 8 of the safety cone 1, and is formed in a predetermined width dimension (dimension in the axial direction).

The width dimension of the ring member 11 is substantially the same as the length of the thick portion 6 in the direction of the axis L1.
The width dimension of the ring member 11 is not particularly limited.

  The ring member 11 has a constant thickness. Specifically, the thickness of the ring member 11 may be in the range of 0.5 mm to 2.5 mm, preferably 0.5 mm to 2 mm, more preferably 0.7 mm to 1.5 mm, and Most preferably, it is set to 9 mm or more and 1.2 mm or less.

  As shown in FIG. 3, the minimum diameter of the inner peripheral surface 11b when the ring member 11 is not mounted is formed to be slightly smaller than the minimum diameter of the outer peripheral surface 4a of the safety cone 1 shown in FIG. Specifically, the minimum diameter of the inner peripheral surface 11b when the ring member 11 is not attached should be smaller than the outer peripheral surface 4a of the safety cone 1 by 2 mm or more and less than 0 mm, and more preferably by 1 mm or more and less than 0 mm.

  More specifically, the minimum diameter of the inner peripheral surface 11b when the ring member 11 is not mounted may be formed in a range of 30 mm to 80 mm, and may be formed in a range of 50 mm to 70 mm. More preferred. The ring member 11 having a minimum diameter of the inner peripheral surface 11b of 30 mm or less grips the small diameter portion of the outer peripheral surface 4a of the safety cone 1 shown in FIG. It is because it becomes easy to get tired. On the other hand, the ring member 11 having a minimum diameter of the inner peripheral surface 11b of 80 mm or less has a position where the safety cone 1 is securely mounted too far from the tip of the safety cone 1 or a gripping diameter becomes too large. This is because it becomes difficult to grasp the cone 1 from above.

As shown in FIGS. 2 and 3, the locking projection 12 is formed on the outer circumferential surface 11 a of the ring member 11 continuously in the circumferential direction around the axis L <b> 2 over the entire circumference. It is a part which locks the finger which holds the grip 10. In addition, a plurality of locking projections 12 are provided at equal intervals in the direction of the axis L2.

In the present embodiment, the cross-sectional shape of the locking convex portion 12 is formed in a substantially triangular shape with the outer peripheral surface 11a as the bottom so that it gradually narrows from the outer peripheral surface 11a in the protruding direction.
The width dimension and the projecting dimension of the locking projection 12 are not particularly limited as long as they can be easily applied to the belly of a human finger, but the width dimension in the direction of the axis L2 is 0.5 mm or more and 2 mm or less, and the projecting from the outer peripheral surface 11a. Although the dimension should just be 0.5 mm or more and 2 mm or less, it is more preferable that it is 0.5 mm or more and 1 mm or less.

Further, the interval between the locking projections 12 and 12 is not particularly limited as long as it is easy to get on the belly of a person's finger, but is preferably 1.0 mm or more and 10 mm or less, and preferably 2 mm or more and 5 mm or less. More preferred.
The inner peripheral surface 11b may be subjected to blasting and mirror finishing.

The grip 10 of the present invention is formed of an elastic body that is relatively easy to expand and contract by a human hand. Examples of the elastic body include rubber. Specifically, natural rubber, styrene butadiene rubber, isoprene rubber, butadiene rubber, chloroprene rubber, butyl rubber, nitrile rubber, ethylene propylene rubber, hyperon, urethane rubber, silicone rubber, fluorine rubber, etc. Is mentioned.
In this embodiment, the grip 10 is formed of silicone rubber suitable for friction with the safety cone 1.

  Since the grip 10 described above has the locking projection 12 on the outer peripheral surface 11 a of the ring member 11, it is easy to lock the finger on the locking projection 12. Therefore, the grip 10 has an effect that even when the safety cone 1 is attached to the safety cone 1, it can be firmly grasped and lifted.

  In addition, since the plurality of locking projections 12 are formed at equal intervals of 1 mm to 10 mm in the direction of the axis L2, the belly of the finger can be easily and reliably hooked on the locking projections 12. Therefore, the grip 10 has an effect that the safety cone 1 can be more reliably grasped and lifted by the plurality of locking projections 12.

Further, the grip 10 has an effect that the grip 10 can be easily gripped from any angle because the locking projection 12 is continuously formed in the circumferential direction on the outer peripheral surface 11a of the ring member 11.
Moreover, since the grip 10 sets the height of the locking projection 12 to 0.5 mm or more and 2 mm or less, the grip 10 can hold the outer peripheral surface 11 a of the ring member 11 while hooking the finger on the locking projection 12. Therefore, there is an effect that the safety cone 1 can be more reliably grasped and lifted via the grip 10.

  Further, since the entire thickness of the grip 10 is set to about 2 mm, a plurality of safety cones 1 can be stacked in the direction of the axis L1 with the grip 10 attached. Therefore, the grip 10 has an effect that the efficiency of the collection operation and the storage operation of the safety cone 1 is good. Furthermore, even with the grip 10 attached, it is possible to use a night lamp or the like for the safety cone 1 attached from above the grip 10.

  Moreover, since the latching convex part 12 of the grip 10 is formed in a shape that is recessed toward the tip, it is easy to put a finger between the latching convex parts 12 and 12. That is, the grip 10 is easy to contact the surface of the ring member 11 by putting the belly of the finger between the locking projections 12, 12 and to easily lock the finger to the lower surface 12 b of the locking projection 12. The safety cone 1 can be grasped more firmly and lifted easily.

  Moreover, since the latching convex part 12 is dented toward the front-end | tip, when the cones C with a grip are piled up, the contact part of the grip 10 and the inner peripheral surface 4b of the safety cone 1 piled up is formed. Can be small. Thereby, there is an effect that it is possible to reduce the area where friction is generated when the cones with grips C are overlapped with each other and prevent the cones with grips C from being easily separated.

Further, since the grip 10 is formed using silicone rubber, the grip 10 can be easily deformed by a human hand, the elastic recovery can be ensured, and the frictional force against the safety cone 1 is appropriate. Therefore, the grip 10 can be securely attached to the outer peripheral surface 4a of the safety cone 1 without using an adhesive or the like. When the safety cone 1 is lifted, the grip 10 is attached by the weight of the safety cone 1. There is an effect that it is possible to prevent the shift or slippage from 1.
Moreover, the grip 10 has an effect that it can be easily detached from the safety cone 1 by hand.

  Further, the inner diameter of the upper end of the grip 10 is slightly smaller than the outer shape of the upper end of the safety cone 1. Therefore, the grip 10 is pushed into the safety cone 1 while being elastically deformed and expanded simply by putting the grip 10 on the upper end of the safety cone 1 and lightly pressing it from above. The grip 10 is easily and firmly mounted at the position where the grip 10 and the upper end surface 4t of the safety cone 1 substantially coincide with each other while firmly gripping the outer peripheral surface 4a of the upper end portion 8 of the safety cone 1 by its elastic return force. There is an effect that can be.

Next, a modified example of the grip 10 will be described by showing only different points from the embodiment described above.
In the present embodiment, an example is shown in which the cross-sectional shape of the locking convex portion 12 is a triangle having the outer peripheral surface 11a as the base, but the cross-sectional shape of the locking convex portion 12 is a trapezoid that is recessed toward the tip. Or other cross-sectional shapes. Specifically, for example, the locking convex portion 12 of the grip 10 is a semicircle having a cross section whose bottom is the outer peripheral surface 11a, and is continuous over the entire circumference in the horizontal direction (circumferential direction) of the grip 10, and the axis L2 A plurality may be formed at intervals in the direction.

Moreover, the latching convex part 12 may be arrange | positioned in the outer peripheral surface 11a at unequal intervals.
Moreover, the latching convex part 12 may be provided intermittently.

Or the latching convex part 12 may be formed with the protrusion of other cross-sectional shapes, such as a semicircle, not strip shape. Specific examples of the outer shape of the locking projection 12 include a hemispherical shape, a cylindrical shape, a triangular shape, a quadrangular shape, and a star shape shown in FIG.
In short, the latching convex portion 12 may have any shape as long as it is easy to put a finger and easily grip the outer peripheral surface 11a of the ring member 11.

Further, the grip 10 may be formed in a tapered shape in which the taper angle of the inner peripheral surface 11 b of the ring member 11 is equal to or smaller than the taper angle of the outer peripheral surface 4 a of the safety cone 1. By setting it as such a structure, there exists an effect that the mounting | wearing to the outer peripheral surface 4a of the upper end part 8 of the safety cone 1 can be strengthened more.
Moreover, since the grip 10 can be attached to the upper end 8 of the safety cone 1 without using an adhesive, the grip 10 can be attached to and detached from the safety cone 1 as necessary. It may be attached in a non-removable manner.
