Description

[Detailed description of the invention] The present invention relates to a pole that can appear and appear on the ground.

Conventionally, this type of pole was attached to an outer cylinder buried in the ground through a bushing that had a structure to hold the pole upright on the ground. Installation requires a large number of parts, such as the need for other bushings to hold this bushing, and it is time-consuming to assemble them.Furthermore, repairing the bushing after installation may cause damage to the part that is attached to the outer cylinder. There was a risk that this would occur.

Therefore, the present invention makes it easy to attach the bushing to the outer cylinder, simplifies repairs after installation, and also makes it possible to freely appear on the ground to protect the outer cylinder and ensure that the outer cylinder is buried underground. This is what we are trying to offer you.

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings.
is an outer cylinder that is buried underground, and has a band-shaped plate 2 wrapped around its upper outer peripheral surface.

Reference numeral 3 denotes a support metal fitting in which window holes 4 are formed, and the support metal fitting 3 has the window holes 4 located above the upper end of the outer cylinder 1, and an appropriate number of the window holes 4 are formed in the band-shaped plate 2.

Reference numeral 5 denotes a pole that is inserted into and out of the outer cylinder 1, and has a lid 7 having a handle 6 at its upper end, and a pin 8 protruding in the diametrical direction near its lower end.

Reference numeral 9 denotes a bushing which holds the pole 5 so as to be able to freely move up and down and rotate nine times, and which is fitted to the upper end of the outer cylinder 1. A flange 10 that covers the upper end of the outer cylinder 1 is provided at the upper end, and a peripheral side surface of the flange 10 is provided at the upper end. A groove-shaped or concave locking portion 11 is formed at a position corresponding to the window hole 4 of the support fitting 3, and below the bushing 9, there is an introduction groove 12 for the pin 8 and an engagement recess continuous thereto. 1
3 are formed symmetrically in the diametrical direction.

Reference numeral 14 denotes a fastening metal fitting having two parallel pieces such as a U-shape or a U-shape. 11, and the bushing 9 is attached to the outer cylinder 1 with this fastening metal fitting 14.
It is attached removably.

Reference numeral 15 denotes a recess provided on the circumferential side of the flange 10 into which the support fitting 3 is fitted.The locking portion 11 is provided in this recess 15, and a groove 16 extending from the recess 15 to the upper surface into which the fastening fitting 14 is fitted is formed. It is formed.

17 is a cover that is fitted onto the bushing 9, and 18 is a screw for mounting the support fitting 3.

Then, the outer cylinder 1 with the support fitting 3 attached to the upper end is buried in the ground with its upper end surface substantially flush with the ground, and the bushing 9 holding the pole 5 is fitted into the outer cylinder 1, flange 10
The locking part 11 on the circumferential side of the bracket 3 is opposed to the window hole 4 of the support metal fitting 3, and the lower piece of the fastening metal fitting 14 is connected to the locking part 11 through the window hole 4, and the upper piece is connected to the upper surface of the flange of the bushing 9. position and fix the bushing 9 to the outer cylinder 1.

As a result, the pawl 5 is attached to the outer cylinder 1 so as to be freely retractable and can rotate nine times, and the raised pawl 5 brings the pin 8 through the introduction groove 12 of the bushing 9 to the engagement recess 13 and maintains the upright state. , the pin 8 is disengaged from the engagement recess 13 and inserted into the outer cylinder 1.

In the present invention, as described above, a support fitting 3 with a window hole 4 provided at the upper end of the outer cylinder 1 is attached with the window hole 4 protruding above the outer cylinder 1.
A bushing 9 provided with a locking portion 11 corresponding to the window hole 4 is attached to the outer cylinder 1 by a fastening fitting 14 that is detachably fitted into the locking portion 11 through the window hole 4. ,
The attachment of the bushing 9, that is, the attachment of the pole 5 to the outer cylinder 1, can be done with a simple operation. When repairing the bushing 9, these can be easily removed on the ground by detaching the fastening fittings 14, and there is no risk of damaging the outer cylinder 1 or the bushing 9 during repair work.

Furthermore, since the support fitting 3 is attached to the outer circumferential surface of the outer cylinder 1, it functions as an anchor for the outer cylinder 1 buried underground, and has the effect of ensuring that the outer cylinder 1 is buried in the ground.

Furthermore, since the support metal fitting 3 is formed on the band-shaped plate 2 that is attached to the outer peripheral surface of the outer cylinder 1, attachment of the support metal fitting 3 to the outer cylinder 1 is made easier, and the anchoring effect of the band-shaped plate 2 is increased. At the same time, the upper part of the outer cylinder 1 can be protected and reinforced, and unexpected shocks caused by the protrusion and retraction of the pole 5 can be coped with.

As described above, the present invention is advantageous in terms of structure, operation, and economy as a pole that can be freely retracted from the ground.
