Description

[Detailed description of the invention] This invention consists of a case body that is buried vertically in the ground with an open top end, and a case body that is fitted into the case body so as to be able to rise and fall freely, and that is latched to the case body in the raised position. This relates to a recessed pole that is combined with a pole.

The present invention is easy to manufacture by using horizontally circular materials for the main components that make up the case and the pole, allowing the whole to exhibit a harmonious cylindrical beauty. The present invention provides a built-in pole that has the following structure.

Examples will be described below with reference to the drawings.

1 is a cylindrical case body; 2 is a cylindrical inner metal fitting that fits inside the upper part of the case body 1; 3 is a cylindrical outer metal fitting that also fits on the upper part of the case body 1; the inner and outer metal fittings 2, 3 is the case body 1
It is fixed by welding, etc. 4 consists of a pair of gutter-like metal fittings 4a fixed to the inner surface of the case body and a cutting groove 4b formed by cutting the side wall of the inner metal fitting 2, and communicates with the case body 1 and the inner metal fitting 2 in the vertical direction. A pair of guide grooves provided in
A rotation groove 6 is formed by cutting the side wall of the inner metal fitting 2 in the horizontal direction and is connected to the upper end of the rotation groove 5. This is a fitting and locking groove cut into the groove. 7
is a cylindrical pole fitted into the inner metal fitting 2 and the case body 1 so as to be able to rise and fall; this pole 7 is provided with a latching rod 8 extending diametrically through the lower part; By fitting the end portion 8' into the fitting latching groove 6, rotation groove 5 and guide groove 4,
While being guided up and down, the raised upper end is rotated horizontally along the rotation groove 5, and then the raised state is maintained by fitting it into the bottom of the T-shaped fitting latching groove 6. can be done. 9
10 is an annular metal fitting that is inserted through the above-mentioned pole 7 and fixed to the upper end surface of the inner metal fitting 2 by a set screw 9', and closes the upper end of the T-shaped fitting groove 6; This flange portion 10 fits into a circular recess 11 formed by the upper surface of the annular fitting 9 and the inner peripheral surface of the outer fitting 3 when the pole 7 is lowered and stored. ,
The pole 7 is supported in a suspended state. Reference numeral 12 denotes a cushioning material attached to the back surface of the circular flange portion 10.

The embedded pole of the present invention configured as described above is
The annular metal fitting 9 together with the case body 1, the inner metal fitting 2, the annular metal fitting 9, and the pole 7 and the circular flange portion 10 at its upper end, each having a cylindrical or disk shape.
The outer metal fitting 3 surrounding the outer circumference of the case body 1 is formed into a cylindrical shape and is fixed to the upper part of the case body 1. Therefore, despite the addition of the outer metal fitting 9, the machining and manufacturing process requires a circular plate at the upper end of the case body. This can be done at almost the same cost as a conventional cylindrical recessed pole with a shaped flange. In addition, when the pole 7 is stored, the circular flange 10 at the upper end of the pole is connected to the outer metal fitting 3.
Since it is stored inside and overlapped with the annular metal fitting 9, the buried state also has a beautiful appearance, resulting in a classy and elegant construction. In addition, since the outer metal fitting 3 has a circular recess 11 formed on its inner peripheral surface, when a toe is placed on the annular edge of the outer metal fitting 3 when using the embedded pole, the inner circular recess 11 If the pole 7 is lowered in this state, there is a risk that the circular flange 10 at the upper end will hit the overly protruding toe. can be evoked. Furthermore, when storing the pole 7, the circular flange portion 10 first fits inside the outer metal fitting 3 and then overlaps with the annular metal fitting 9, so that the toes that have protruded too far inward as described above suddenly become attached to the circular flange. There is no possibility that the part 10 and the annular metal fitting 9 will be pinched. In addition, by burying the case body 1 with the top surface of the circular recess 11 at the same height as the ground surface, it is possible to prevent it from interfering with traffic when not in use, or to make the bottom surface of the circular recess 11 almost flush with the ground surface. By burying the case body 1 at a height of , it is possible to bury an embedded pole that prevents rainwater and earth from flowing into the case body 1 from the ground surface. In addition, a pair of guide grooves 4 are provided in the vertical direction that communicate with the inner surface of the case body 1 and the inner surface of the inner metal fitting 2, and a rotation groove 5 is provided in the horizontal direction in series with the upper end of the guide groove 4. At the tip of the groove 5, a fitting and locking groove 6 is provided whose upper end is open to the upper edge of the inner metal fitting 2 and continues in a T-shape. A latching rod 8 is provided in the lower part in the diametrical direction, and both outer ends 8' of the latching rod 8 are fitted into the fitting latching groove 6, rotation groove 5 and guide groove 4, and the inner fitting Since the annular metal fitting 9 is screwed to the upper end surface of the inner metal fitting 9, the locking rod 8 is fitted into the fitting latch groove 6 opened at the upper edge of the inner metal fitting 2 before screwing the annular metal fitting 9. Insert pole 7 into case body 1
The pole 7 can be easily installed by fitting the rod 8 into the guide groove 4 by rotating it horizontally, and then screwing the annular fitting 9. Since the pole 7 can be pulled out by removing the annular metal fitting 9 in the procedure, it is easy to assemble the embedded pole and inspect the inside of the case body during use, such as removing dirt accumulated at the bottom. Further, the pole 7 is supported in the upright state by having a retaining rod 8 engaged with the lower part of the fitting retaining groove 6 which is connected to one end of the rotation groove 5 in a T-shape. Another advantage is that it prevents rotation and can be used safely.
