Description

[Detailed explanation of the invention] This invention consists of an outer cylinder that is buried in the soil with its upper end exposed to the ground surface, and a cylinder that is fitted into the outer cylinder so that it can be raised and lowered, and that is latched onto the outer cylinder when it is raised. The present invention relates to a vertical embedded pole consisting of a pole configured to.

Conventional vertical embedded poles have a vertical guide groove on the inner surface of the outer cylinder that is buried in the soil, a hook-shaped hook-shaped hook groove on the upper end of the groove, and a hook-shaped hook groove on the lower side of the pole. The projecting latch pin is fitted into the groove to secure the pole pulled upward from the outer cylinder, and the outer cylinder with the guide groove is made of synthetic resin. This method requires an expensive mold, and has the disadvantage that the guide grooves are easily distorted or twisted during molding, making it difficult to obtain a uniform product.

In addition, the earlier applications include Utility Model Publication No. 5151558 and Utility Model Number 54-
There is a vertical embedded pole constructed as in No. 21379, but the former has an inner cylinder whose upper edge is fixed to the upper end of the outer cylinder, and an arcuate guide part, a guide groove, a latching groove, and an insertion groove from the lower end. A series of grooves are formed continuously, and a pole with a protruding locking pin at the bottom is fitted into this inner cylinder, and then a lock piece having bent pieces at the top and bottom is fitted into the insertion groove. The latter is configured to have an elastic piece fixed to the lower end of the pole, which is engaged by frictional resistance with the inner circumferential surface of the outer cylinder, so as to guide the raising and lowering of the pole and also to engage the pole.

Therefore, although neither of them has a guide groove corresponding to the length of the outer cylinder, in the former case, it is technically difficult to adjust the gap between the pole and the inner cylinder, and the pole in the upward latched state tends to wobble, causing wobbling and other problems. There are many drawbacks, such as the fact that if the groove that engages the locking pin is damaged, the entire inner cylinder must be replaced.

In addition, the latter has the disadvantage that the pole cannot be raised and lowered smoothly, and that the pole is unstable to be latched when raised, and even a slight excessive load causes the pole to descend unexpectedly, making it impractical.

Therefore, the present invention is to form an arc-shaped guide part, a guide groove, a latching groove, and an insertion groove in the same order in the vertical direction at the lower end in an outer cylinder that is buried in the soil with the upper end exposed on the ground surface. In addition to fitting a pair of poles with fixed large diameter parts so that they can be raised and lowered,
The insertion groove, the latching groove, the guide groove, and the arcuate guide portion are engaged with the latching pins that project from the upper inner surface of the outer cylinder and are arranged diametrically opposite each other, and the upper end of the outer cylinder is fitted with a pole. By providing a pair of left and right cover plates formed in a half-shape, each of which is fixed via a screw with a circumscribed central hole, a vertical embedded pole is provided that is easy to manufacture, install, and operate. be.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, 1 is an outer cylinder buried in the soil with its upper end 1' exposed to the ground surface G, 2 is a pole fitted into the outer cylinder 1 so as to be able to freely rotate and move up and down, and 2' is the lower end of the pole 2. A pair of left and right large diameter portions are fixed to each other by screws 6.

This large-diameter portion 2' vertically divides a pipe having a thickness to synchronize with the inner surface of the outer cylinder 1 into two parts, and forms an arcuate guide part 4' at the upper edge, and between the side edges, A guide groove 4 that continues vertically below the guide portion 4', a locking groove 5 that extends horizontally from the lower end of the gap groove 4 to one side, and an insertion groove that opens downward from the inner end of the gap groove 5. Insertion grooves 4'' are formed in the same shape on the front and rear surfaces of the pole 2.

Locking pins 7, 3 are provided diametrically opposite to each other on the inner surface of the upper part of the outer cylinder 1 and engage with the arcuate guide portion 4', the guide groove 4, the locking groove 5, and the insertion groove 4''. 7 is provided with a center hole 7' that circumscribes the pole 2 on opposite sides, and is fitted into the upper end 1' of the outer cylinder 1 while holding the pole 2 from both sides.
This is a pair of left and right half-shaped lid plates that are fixed to the upper end 1'.

As mentioned above, the embedded pole of the present invention has the upper end 1 of the outer cylinder 1.
Since it has a half-shaped cover plate 7 which has a center hole 7' circumscribing the pole 2 and is fixed with a screw 8, the pole 2 having the large diameter part 2' at the lower end can be attached to the outer cylinder 1. When attaching and detaching, by loosening the screws 8 and dividing the cover plate 7, only the pole 2 can be inserted and removed, making it possible to easily install and repair the embedded pole after construction.

Further, the pair of left and right large-diameter portions 2' fixed to the lower end of the pole 2 are provided with an arcuate guide portion 4' and a guide groove 4 that engage with a latch pin 3 protruding from the inner surface of the outer cylinder 1. Since the stop groove 5 and the insertion groove 4'' are formed, the contact between the pole 2 and the inner surface of the outer cylinder 1 can be smoothly raised and lowered without rattling over the entire length. The pole 2 is kept in a stable upright state without wobbling even in the raised fixed state in which the pawl 2 is engaged with the locking groove 5.

Furthermore, according to the present invention, if the guide groove 4, the latching groove 5, etc. are damaged due to an incorrect usage operation or the application of an unexpected external force, the pole 2 can be pulled out as described above and the damaged side Repairs can be easily and inexpensively carried out by replacing the large diameter portion 2'.

Also, a cover plate 7 that guides the raising and lowering of the pole 2 at the upper end 1' of the outer cylinder 1, an arcuate guide portion 4' that engages with the latch pin 3 when the pole 2 is raised and lowered, a guide groove 4, and a stopper groove. 5 and the insertion groove 4'' are formed separately, so there is no need to use a separate lock piece or the like to close the insertion groove 4'' after the pole is fitted, as in the previous application. It has practical effects not found in conventional products in that it is easy to manufacture, install, and operate as a whole.
