Abstract
A specific connecting rod for traffic cones includes an outer rod and an inner rod positioned in the outer rod to telescope therein. The outer ends of the outer rod and of the inner rod are respectively fixed with a socket with a ring fitting around a traffic cone so that the connecting rod can be connected between two traffic cones. The outer rod and the inner rod further respectively have a stop ring fixed on their inner end to keep the inner rod from falling out of the outer rod in telescoping to adjust the whole length of the connecting rod. The light reflective material on the outer surface of the outer rod and the inner rod is never scarred by telescoping movement of the inner rod or by placing the connecting rod on the ground, keeping intact the light reflecting function of he connecting rod.
Description
- This invention relates to a specific connecting rod for traffic cones, particularly to one consisting of an inner rod and an outer rod combined together to mutually telescope to adjust the whole length of the connecting rod. The outer rod has a stop ring in an inner end for stopping the inner rod from falling out, and the stop ring cannot scar the reflective material coated on the inner rod, and the reflective material coated on the outer rod cannot be scarred when the connecting rod is placed on the ground. So the specific connecting rod for traffic cones in the invention always maintains good light reflecting effect.
- A first conventional connecting rod for traffic cones shown in
FIGS. 1 and 3 includes aninner rod 10 and anouter rod 11 for theinner rod 10 to extend therein to telescope so as to let the length of the connecting rod adjustable. Theinner rod 10 has afitting ring 100 connected with its outer end, and theouter rod 11 has afitting ring 110 connected with its outer end for respectively fitting around a traffic cone so as to connect two traffic cones together for cordoning a region. The telescoping function of theinner rod 10 with theouter rod 11 enables the connecting rod convenient for storing, transporting, and packaging and using. Further, theouter rod 11 has its outer end provided with anstop ring 111 fitted in its inner wall, and theinner rod 10 has its inner end provided with anouter stop ring 101 so theinner rod 10 may not fall out of theouter rod 11 by mutual blocking of the twostop rings inner rod 10 is telescoped to the longest. Although thestop rings inner rod 10, the section where the inner end of theinner rod 10 abutting to the inner end of theouter rod 11 may sag down owing to no supporters when theinner rod 10 is telescoped to form the longest length of the whole connecting rod as shown inFIG. 1 . So theouter rod 11 may have theouter surface 103 of its inner end with any protective means to touch the ground, and some section of theouter rod 11 may touch the ground to produce some scar to the reflective material on the outer surface of therod 11, and the night-light reflective effect may be reduced. - Another conventional connecting rod for traffic cones shown in
FIG. 2 includes aninner rod 13 and anouter rod 14 combined to telescope mutually to let the length of the connecting rod adjustable. Theinner rod 13 has itsinner end 130 shaped like a trumpet, but theouter rod 14 has itsinner end 141 shrunk to fit closely around theinner rod 13, with the rest portion except the inner end having a larger inner diameter than the outer diameter of theinner rod 13. So the mutual contact of theinner end 130 with theinner end 141 may stop theinner rod 13 from falling out of theouter rod 14. But the disadvantage is that theinner end 141 is sharp to produce scar to thereflective material 142 on the outer surface of theinner rod 13 during telescoping to worsen the night light reflective effect. Moreover, theinner end portion 143 of theouter rod 14 has no protective means, so the reflective material on the outer surface of theouter rod 14 may receive scar if the connecting rod is placed directly on the ground as shown inFIG. 3 . In addition, the trumpet shape of the inner end of theinner rod 13 and the shrunk shape of the inner end of theouter rod 14 takes time in their making process, slowing down the speed of production. - The feature of the invention is an inner rod and an outer rod combined to mutually telescope to form a specific connecting rod for traffic cones. The inner and the outer rod respectively have a stop ring provided at an inner end of a cross-section of an inverted T-shape. The stop ring of the inner rod is positioned in the inner surface, and that of the outer rod is positioned on an outer surface to fit around the inner rod. So the stop rings of the inner and the outer rod can keep the stability of the connecting rod, whether they are telescoped to meet or not meet each other.
- One more feature of the invention is that the outer diameter of the stop ring of the inner rod is equal to the inner diameter of the outer rod, and the inner diameter of the small portion of the stop ring is equal to the outer diameter of the inner rod. Therefore, the center portion of the connecting rod can be kept straight, not sagging down, even if the inner rod and the outer rod are telescoped to form the longest length of the connecting rod.
- This invention will be better understood by referring to the accompanying drawings, wherein:
-
FIG. 1 is a partial cross-sectional view of a first conventional connecting rod for traffic cones; -
FIG. 2 is a partial cross-sectional view of a second conventional connecting rod for traffic cones; -

FIG. 8 is a perspective view of the specific connecting rod for traffic cones practically used in a second way in the present invention; and, -
FIG. 9 is a perspective view of the specific connecting rod for traffic cones practically used in a third in the present invention. - A preferred embodiment of a specific connecting rod for traffic cones, as shown in
FIG. 4 , includes aninner rod 2 and anouter rod 3 for theinner rod 2 to extend and telescope therein to adjust the whole length of the specific connecting rod. - The
inner rod 2 has its outer surface coated with a lightreflective material 20 of a comparatively stark brilliant color such as red, orange, etc., and asocket 22 fixed on an inner end and having asocket end 220 and aring 221 extending outward from the outer end of thesocket 22. Thecenter hole 2200 of the socketinner end 220 fits around the outer end of theinner rod 2 and then fixed tightly with ascrew 2211 with theouter end 21 of theinner rod 2. Then, thering 221 can fit around atraffic cone 4 as shown inFIG. 7 . Theinner end 23 of theinner rod 2 is fixed with astop ring 24 of a cross-section of an inverted T-shape, having asmall diameter portion 240 and alarge diameter portion 241, with thesmall diameter portion 240 fitted in ahole 230 of theinner end 23 as shown inFIGS. 5 and 6 . - The
outer rod 3 has its outer surface coated with lightreflective material 30 of a comparatively stark brilliant color such as red, orange, etc., and asocket 32 with anouter end 320 and aring 321 extending outward. Theouter end 320 of thesocket 32 has acenter hole 3200 to fit around theouter end 31 of theouter rod 3 and fixed tightly with ascrew 3211. Thering 321 can fit around atraffic cone 4 so as to connect the connecting rod between twotraffic cones 4, as shown inFIGS. 7, 8 and 9 in various ways. Further, theouter rod 3 has itsinner end 31 connected with astop ring 34 of a cross-section of an inverted T-shape having asmall diameter portion 340 and alarge diameter portion 341, with thelarge portion 341 fitting around theinner end 33 as shown inFIGS. 4, 5 and 6. - In assembling, the
stop rings inner rod 2 and theouter rod 3, and then theinner rod 2 is inserted in theouter rod 3, with theouter end 21 of theinner rod 2 extending through thehole 310 of theouter rod 3 as shown inFIGS. 5 and 6 and exposes out of theouter rod 3. Then thesockets inner end 23 of theinner rod 2 and theinner end 33 of theouter rod 3, finishing assembly of the connecting rod for traffic cones in the invention. - Next, After the
inner rod 2 telescopes in theouter rod 3, the center portion of the connecting rod may not sag, but keep its straightness even when theinner rod 2 telescopes to let the connecting rod have the longest length, because the outer diameter of thelarge portion 241 of thestop ring 24 is equal to thehole 310 of theouter rod 3, the outer diameter of theinner rod 2 is equal to the inner diameter of thesmall portion 340, and thelarge portion 241 and thesmall portion 340 both have a proper length. In addition the connecting rod cannot touch the ground even it is placed on the ground, without happening any problem of the light reflective material of the connecting rod being scared. Moreover, thecontact portion 342 of theinner rod 2 and theouter rod 3 is shaped curved, impossible to scar the light reflective material of the inner and theouter rod inner rod 2 so as to keep intact the light reflecting function of the connecting rod. - While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
