JPS5912254Y2 - Recessed tube for erecting a pole or fence - Google Patents

Description

[Detailed explanation of the idea] This idea is to temporarily erect poles to set up flags and tents, fences to divide the area, etc., by burying them in places such as plazas in residential complexes. Regarding the embedded tube.

When temporary events are held within a housing complex, it is difficult to erect things like pillars in the concrete-paved plaza, and the facilities often end up being incomplete.

The present invention provides an embedding tube that can be easily used in the above-mentioned cases by being installed in advance.

Embodiments of the present invention shown in the drawings will be described below.

Reference numeral 1 indicates an embedded cylinder main body which has an appropriate thickness and is buried vertically in the ground by extending an outwardly protruding anchor plate 4 in the middle; The flange metal fitting 3 exposed on the surface GL is a removable lid that rotatably fits into the flange metal fitting 2 and closes the upper end of the embedding cylinder main body 1.

The lid 3 has a circumferential groove 5 on the lower outer circumferential surface, a locking pin 8 protruding into the circumferential groove 5, and a pair of notches 7 reaching the circumferential groove 5 from the diametrical direction of the lower edge. Align the notches 7 with a pair of retaining pins 6 protruding in the diametrical direction on the inner circumferential surface of the flange fitting 2, fit them into the flange fitting 2 from above, engage the circumferential groove 5 with the pins 6, and then remove the lid. 3 is rotated in the circumferential direction to bring the stopper pin 8 into contact with the stopper pin 6, thereby preventing it from slipping out upward and rotating in one direction when closed.

In the figure, 3' is an insertion hole for an attachment/detachment tool that opens on the top surface of the lid 3, 9 is a pair of vertical grooves diametrically opposed to each other on the upper edge of the embedding cylinder main body 1, and 10 is a hole for inserting an attachment/detachment tool into the top surface of the lid 3; By providing a protrusion in the lower part of the column inserted into the main body 1 with a shaft provided in the diametrical direction of the bottom part of the column, which matches the vertical groove 9, the erected column can be prevented from inadvertent rotation and removal.

Further, the lower end of the erected support is supported by the shaft 10, and is prevented from directly touching the earth and sand deposited on the bottom surface of the embedding tube.

As described above, the anchor plate 4 is provided in the middle part of the embedding cylinder main body 1, and the lid 3, which is provided with a circumferential groove 5, a locking pin 8, and a notch 7 on the lower outer peripheral surface, is attached to the flange fitting 2 fixed to the upper end. According to the present invention, the lid 3 is removably fitted and secured to a retaining pin 6 provided on the inner circumferential surface of the flange fitting 2 to prevent the lid 3 from coming off and rotating in one direction. The embedding cylinder main body 1 is firmly fixed under the embedding, and the stability is excellent when the lid 3 is removed and a temporary pillar is erected.

Further, when not in use, the lid 3 is held within the flange fitting 2 by the engagement between the circumferential groove 5 and the retaining pin 6, so that the lid 3 will not come off accidentally when a car or the like passes by.

Further, by turning the locking pin 8 of the lid 3 to a position where it contacts the locking pin 6, the installation positions of the notch 7 and the locking pin 6 are shifted from each other, and the lid 3 can be held more reliably. It has practical effects such as being able to perform
