Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pole attachment band device for attaching cables, instruments, etc. to a pole body.

[Prior Art] Conventionally, in order to attach electric cables and various devices to a pole such as a utility pole, a stainless steel band is wrapped around the column and the ends of the band are tightened with a tightening device, and the cables and devices are secured with this band. It was installed.

In order to securely attach such cables and equipment, the stainless steel band must be tightened strongly, but there is a problem that if the band is tightened too tightly, the hard edge of the stainless steel band will dig into the plastic coating of the cable and damage it. Ta.

In addition, when wrapping such a stainless steel band around a column, the corner edge of the band may injure the worker's hand. It is known that both ends of the strap are curved in an arcuate manner, and several grooves and arcuate surfaces are provided on both the front and back sides.
This is a problem in that although it is possible to prevent injuries to hands and fingers, when the strap is tightened strongly to securely attach an electric cable, etc., the hard strap can bite into the cable's plastic coating and cause damage, and this cannot be prevented. The dot was hot.

In addition, in order to prevent damage to vinyl greenhouses, it is known that plastic is integrally extruded and coated around the outer periphery of a plastic strip core material, as shown in Utility Model Application Publication No. 55-163738. Because the coating is fused together, it is not possible to place the coating only on the part where the cable or device is to be held down and attached, and since there is also plastic coating on the end of the band-shaped core material, it is difficult to place the coating on the end of the stainless steel band It could not be used as a tightener for tightening.

In order to solve the above-mentioned problems, the present invention provides a pole mounting band device that can be reliably attached to electrical cables and the like without damaging their coverings.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the pole mounting band device of the present invention has the lower surface of the stainless steel elongated strip 1 formed into a flat surface 2, and the lower surface of the elongated strip 1 made of stainless steel. The upper surface of the central portion of the elongated strip plate 1 is formed into a concave portion by forming a thin central portion 3 in the longitudinal direction at the central portion and thick side edges 4 and 5 at both longitudinal edges, And each side edge of this thick side edge part 4,5 is circular arc surface 6,7
At the same time, the upper surfaces of the thick side edges 4 and 5 are formed into flat parts 8 and 9, and a flat and elongated transparent plastic cover 1 is attached to the elongated strip plate 1 formed in this way.
0 is slidably inserted thereinto, and the base end 25 of the elongated strip plate 1 is locked to the tightening device 11.

[Function] The stainless steel elongated strip 1 is formed with a flat lower surface, a thin central portion in the longitudinal direction, and thick side edges on both sides to form an elongated strip. By forming the upper surface of the central part into a recess, the plastic cover that is inserted into this strip does not come into close contact with the plastic cover, so it can be inserted and slid freely. It becomes possible to cover only the portion of the entire length of the elongated strip that presses the cable with the plastic cover, without covering the end that is wrapped with the cincher during installation.

Further, by forming a concave portion on the upper surface of the central portion of the elongated strip and covering it with a transparent plastic cover, a sign or a display board can be inserted into the concave portion to display information.

[Examples] Examples of the present invention will be described below with reference to the drawings. FIG. 1 shows a top view of the pole mounting band device of the present invention,

In the figure, reference numeral 1 denotes a stainless steel elongated strip plate, which is one continuous strip plate, but the intermediate portion is not shown and both ends are shown locked to the cincher. The lower surface of the elongated strip 1 is formed into a flat surface 2, and the central portion of the elongated strip 1 is made thinner in the length direction to form a thinner central portion 3, and both longitudinal edges are thickened side edges. By forming the portions 4 and 5, the upper surface of the central portion of the elongated strip 1 is formed into a recessed portion. Further, the respective side edges of the thick side edges 4 and 5 are formed into arcuate surfaces 6 and 7, and the respective upper surfaces of the thick side edges 4 and 5 are formed into flat portions 8 and 9.

Reference numeral 10 denotes a transparent plastic cover shaped like a flat elongated bag made of transparent vinyl resin or the like, and the aforementioned elongated stainless steel band plate 1 is slidably inserted into the central cavity of the transparent plastic cover 10.

Reference numeral 11 denotes a tightening device, which forms a U-shaped frame with both side plates 12 and 13 and a bottom plate 14.

Saw teeth 18 are formed on the end surface of the U-shaped frame facing the side plate 13. An annular sawtooth protrusion 19 is provided to protrude from the side surface of the side plate 13 so as to face the sawtooth 18, and the sawtooth protrusion 19 is engaged with the sawtooth protrusion 18 to form a ratchet. Reference numeral 20 denotes a retaining ring fitted onto the winding shaft 15 protruding outside the other side plate 12 of the U-shaped frame and brought into contact with the outer surface of the side plate 12; cotter pin 21
is inserted to connect the retaining ring 20 and the winding shaft 15. This allows the ratchet to rotate without the winding shaft 15 coming off the side plates 12 and 13. The winding shaft 15 is provided with a band locking groove 22 between the side plates 12 and 13, and the bottom plate 14 of the U-shaped frame is provided with band insertion holes 23 and 24 as shown in the fifth figure.

In order to attach an electric cable or the like to a column such as a telephone pole using the pole attachment band device of the present invention constructed as described above, the electric cable or the like is attached to the column, and the bottom plate 14 of the tightening device 11 is attached to the column. The cable is kept in contact with the column, and the stainless steel elongated strip 1 covered with the transparent plastic cover 10 is wrapped around the column to hold the cable.
If the tip of the elongated strip 1 is inserted into the band locking groove 22 of the winding shaft 15 and bent, and the winding shaft 15 is turned in the direction of the arrow in FIG.
Since it is wound around the column, it is wrapped tightly around the column.
It will be tightened by the ratchet mentioned above.
Tightening by this ratchet is achieved by turning the rectangular head 16 of the winding shaft 15 with a tool and moving the serrated disc part 17 into the fourth

As a result, the sawtooth protrusion 19 is pressed to the left in FIG. It will bend to the left (upward in Figure 1). Therefore, the saw teeth 18 of the disc part 17 are
Since the winding shaft 15 can advance over the sawtooth projections 19 of No. 3 one after another, the winding shaft 15 can rotate in the above-mentioned direction, and when the winding shaft stops rotating, the sawtooth projections 18 and the sawtooth projections 19 engage in the state shown in the figure. Therefore, reverse rotation is prevented. By continuing to rotate the winding shaft 15 in one direction in this way, the elongated strips 1 can be wound around the winding shaft 15 one after another and tightened around the circumferential surface of the column, and electric cables etc. can be attached to the column. be. In order to loosen and remove the elongated strip 1 that has been tightened as described above, it is possible to pull out the retaining split pin 21 and pull out the retaining ring 20 upward in FIG. Since the saw teeth 18 can be pulled out downward in FIG. 1 and separated from the saw tooth protrusions 19, the winding shaft 15 can be rotated in the opposite direction, and the elongated strip plate 1 can be loosened and removed.

[Effects of the invention] As mentioned above, the present invention forms the lower surface of the stainless steel elongated strip into a flat surface, the central part is formed into a thin inner central part in the length direction, and both side edges are formed into thick side edges. Since the upper surface of the central part of the elongated strip plate was formed into a recessed part,
Since the plastic cover that is inserted into this strip plate does not stick tightly, it can be inserted freely and slidably. Therefore, when attaching an electric cable etc. with a long stainless steel strip plate, it is possible to cover the end that is wrapped with a tightening device. This makes it possible to cover only the part that holds the cable of the entire length of the elongated strip with a plastic cover.
Therefore, the corner edges of the stainless steel band do not dig into and damage the plastic sheathing of the cable, and the cable can be securely tightened to attach the cable. Furthermore, since the upper surface of the central portion of the elongated strip is formed into a recessed portion and covered with a transparent plastic cover, a sign or a display board can be inserted into this recessed portion for display purposes.
