JPH1129912A - Collar cone with distance adjustment device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent a bar from taking space when stored, as a conventional safety fence linked by the bar takes much space because of the bulkiness of the bar during storage and the length encompassing a road construction site is limited to the bar length, so that several kinds of bars of different lengths are required, and to enable the safety fence to be constructed to the desired length. SOLUTION: A winding mechanism for a fence tape 1 is enclosed in a collar cone 4 from which the fence tape 1 can be drawn out by the desired distance, and the winding mechanism has a winding drum 1b secured to its winding shaft 1a, with a spring 2 attached to the winding shaft 1a to provide activation in the opposite direction to the direction in which the fence tape 1 is drawn out from the collar cone 4. Further the collar cone 4 is provided with a stopper 3 for stopping rotation of the winding shaft 1a in the activating direction when the fence tape 1 is drawn out from the collar cone 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention A color cone with an adjustable distance device for displaying the location of road construction.

[0002]

2. Description of the Related Art Heretofore, a safety fence for indicating a place of road construction has connected a color cone with a bar. However, the safety fence connected by a bar not only takes up space because the bar is large when it is stored, but also the length of the bar surrounding the location of road construction is limited, so several types of different lengths Needed a bar.

[0003]

The object of the present invention is to prevent the bar from taking up space when storing the bar, and to provide a safety fence to an arbitrary length.

[0004]

[Technical Means] A take-up mechanism for the fence tape 1 is housed in a color cone 4 from which the fence tape 1 can be pulled out by a required distance. The take-up mechanism fixes a take-up drum 1b to a take-up shaft 1a. A spring 2 is attached to the winding shaft 1a to urge the fence tape 1 in a direction opposite to a direction in which the fence tape 1 is pulled out from the color cone 4.

A stopper 3 for stopping rotation of the take-up shaft 1a in the biasing direction when the fence tape 1 is pulled out from the color cone 4 is provided with a stopper 3 on the color cone 4, and a color cone with a distance-adjustable device. .

[0006]

Embodiments of the present invention will be described below. 1 to 5, reference numeral 1 denotes a fence tape.
As shown in FIG. 5, one end is attached to the winding drum 1b, and the hook 1d is attached to the tip. Reference numeral 1e denotes a guide plate for guiding the upper and lower surfaces of the wound tape 1. 1a is a winding shaft of the winding drum 1b.

As shown in FIG. 3, for example, the winding mechanism of the fence tape 1 passes through the winding shaft 1a through guides 1c, 1c provided integrally with the inner wall of the color cone 4, and the winding drum 1 is wound on the winding shaft 1a. 1b is fixed.

Reference numeral 2 denotes a leaf spring, one end of which is fixed to the take-up shaft 1a and the other end of which is fixed to the case 2c, for urging the take-up shaft 1a in a direction opposite to the direction in which the tape 1 is pulled out. (FIGS. 3 and 5) It is desirable that the case 2c be fixed to the guide plate 1c. Reference numeral 3 denotes a stopper, and 3a denotes a stopper locking hole of the winding shaft 1. 4 is a color cone, 4a is a tape pull-out slit, and 4b is a tape locking slit.

The operation of the color cone of the present invention will be described below. FIG. 1 is a horizontal sectional view at the time when the fence tape 1 is pulled out from the tape pull-out slit 4a of one color cone 4, and the hook 1d is locked in the tape locking slit 4b of the adjacent color cone 4. Show.

At the time of FIG. 1, the stopper 3 is locked in the stopper locking hole 3a of the winding shaft 1a, and the rotation of the winding shaft 1a is stopped. In other words, the winding shaft 1 is not biased by the leaf spring 2.

FIG. 5 shows that the drawing direction (arrow y) of the fence tape 1 and the urging direction y of the winding shaft 1a are opposite to each other. FIG. 2 is a perspective view of the winding mechanism of the fence tape 1, and FIG. 3 is a sectional view. FIG. 5 is an external view of the color cone 4.

As described above, in FIG.
Is pulled out in the urging direction (x in FIG. 5) of the leaf spring 2 and is locked by the locking slit 4b of the adjacent color cone 4, so that if the stopper 3 is not operated, the adjacent color cone 4 is tilted in the biasing direction of the leaf spring 2.

[0013]

【effect】

(A) Since the fence tape 1 is stored in the color cone 4 when it is stored, it does not take up much space.

(B) Since the fence tape 1 is urged in the direction opposite to the pulling-out direction from the color cone 4, the fence tape 1 is rotatably stored in the color cone 4 when the hand is released.

(C) When the fence tape 1 is stretched between the adjacent color cone 4 and the adjacent color cone by locking the rotation of the winding shaft 1 a with the stopper 3, the adjacent color cone is biased by the spring 2. 4 will not be defeated.

D) The fence tape 1 can be freely set even if the environmental conditions of the road are different since the stretched distance can be freely set.
