Description

The present invention relates to a sheath pipe that is embedded and fixed to an installation surface to support a pillar-shaped object such as a car stopper, and to an installation structure for the pillar using this sheath pipe.

The configuration in which a cylindrical sheath pipe with a bottom is buried and fixed in the installation surface, and the lower part of a pillar-shaped object such as a car stopper is inserted inside the sheath pipe and set upright has been used for a long time, and various inventions have been disclosed.

For example, Patent Document 1 describes a car stop post comprising a cylindrical base cylinder buried in the ground with its upper opening facing the ground surface, a disk-shaped lid that opens and closes the upper opening of the base cylinder, a lid opening/closing mechanism that pivots the lid to the base cylinder, and a support body that is fitted into the base cylinder so that it can be raised and lowered and is held upright on the ground by a predetermined fixing means. The lid opening/closing mechanism comprises a support shaft housing that protrudes from the upper side surface of the base cylinder and has an internal cavity that opens upward and in which a pivot shaft is disposed along the tangential direction of the base cylinder, and a receiving portion that protrudes outward from the outer periphery of the lid and is received in the internal cavity of the support shaft housing. The disclosed configuration of a car stop post includes a support piece having an upward bearing groove formed in the receiving portion, into which the pivot shaft is inserted via an upwardly opening groove, and a supporting piece connected to the cover via a predetermined connecting means, which is housed in the internal space of the support shaft housing in the connected state, and which has a downward bearing groove formed in the receiving portion, into which the pivot shaft is inserted via a downwardly opening groove. The supporting piece and the supporting piece are housed in the internal space of the support shaft housing, and the bearing groove of the supporting piece rotatably supports the cover on the pivot shaft, thereby pivoting the cover to the cylindrical base body.

Japanese Patent Application Laid-Open No. 2017-203289

The bollard post shown in Patent Document 1 is designed so that the lid can be easily replaced if it is deformed or damaged by being run over by a vehicle or other vehicle, but there is a risk that the lid could be removed by vandals when the bollard post is in use and erected.

The present invention provides a sheath tube that can prevent the lid from being removed by tampering, and a columnar body installation structure using the sheath tube.

In order to achieve the above object, the present invention has the following configuration.
In other words, the sheath pipe of the present invention is a sheath pipe that is buried and fixed in an installation surface to support a pillar-shaped body such as a car stopper, and comprises a bottomed, cylindrical main body tube having an opening at the top, and a lid body that is pivotally supported on the shaft of the main body tube to open and close the opening, a fastening member is attached to the lid body, and the lid body can be removed from the shaft by releasing the fastening of the fastening member and removing it axially outward, and the fastening member is characterized in that when the lid body is in a state where it blocks the opening of the main body tube, the axially outward side faces upward , making it removable from the lid body, and when a pillar-shaped body can be inserted inside the main body tube, the axially outward side faces a wall portion provided at the top of the main body tube, making it unremovable from the lid body.

The sleeve tube of the present invention comprises a bottomed, cylindrical main tube with an opening at the top, and a lid pivotally supported on the shaft of the main tube to open and close the opening of the main tube. By closing the opening with the lid, the intrusion of dust and other debris into the interior of the main tube can be reduced. Furthermore, a fastening member is attached to the lid, and the lid can be removed from the shaft by releasing the fastening member. Therefore, if the lid is deformed or damaged due to a vehicle or other object coming into contact with a column supported by the sleeve tube installed on an installation surface, the fastening member can be released, allowing the lid to be removed from the shaft and easily replaced. Furthermore, because the fastening member is configured to be unremovable from the lid when a column can be inserted inside the main tube, removing the lid from a sleeve tube used to install a column such as a car stopper is extremely difficult, preventing the lid from being removed by tampering or other means.

Furthermore, if a lid mounting section with a wall is formed on the top of the main tube, and the shaft section is positioned in the hollow section inside this lid mounting section, and the lid mounting section is formed so that the wall section is positioned in the axial direction of the head of the fastening member when a pillar-shaped body can be inserted into the main tube, then in a sleeve tube used to install a pillar-shaped body such as a car stopper, the wall section will prevent the use of a tool to release the fastening of the fastening member, effectively making the fastening member unremovable, which is preferable.

Furthermore, if the uppermost end of the wall portion of the lid attachment section is positioned near the installation surface, and the entire fastening member is positioned below the uppermost end of the wall portion when a columnar object can be inserted inside the main tube, then in a sleeve tube used to install a columnar object such as a car stopper, the wall portion or installation surface will prevent the use of a tool to release the fastening member, effectively making the fastening member unremovable, which is preferable.

Furthermore, if the sheath pipe is buried and fixed in the installation surface and supported by a pillar, it becomes extremely difficult to remove the lid from the sheath pipe when it is used to install a pillar such as a car stopper, thereby preventing the lid from being removed by tampering, etc.

The installation structure for the sheath tube and columnar body according to the present invention can prevent problems such as the lid being removed from the sheath tube by tampering when a columnar body such as a car stopper is installed and in use.

The cover 40 has an oval through-hole 40a formed therein, which penetrates the cover 40 in the vertical direction.
The mounting portion 41 comprises a roughly rectangular plate-shaped base portion 42 that connects to the lid portion 40, and a plate-shaped support portion 43 that extends downward from the edge of the base portion 42, and two support portions 43 are formed at intervals around the circumferential direction of the lid portion 40.

A groove 44 is formed in each support portion 43 of the mounting portion 41, and each groove 44 is formed in the shape of a notched groove extending from the outside to the inside in the direction in which the mounting portion 41 projects.
Each groove 44 is provided so that the shaft 33 can be inserted into the inside thereof, and the cover 4 is provided so that the shaft 33 is inserted into the inside of each groove 44 to pivotally support each support portion 43 .

A restricting member 5 is attached to the mounting portion 41 so that the inserted shaft portion 33 does not come off from the inside of the groove portion 44 , and the restricting member 5 is detachably attached to the mounting portion 41 .
The regulating member 5 has a regulating body 50 that is arranged on the outside of the shaft portion 33 and regulates the shaft portion 33 from coming out of each groove portion 44, and a fastening member 55 for attaching the regulating body 50 to the mounting portion 41, and the regulating body 50 is attached to the underside of the base 42 by the fastening member 55 which is a male threaded member such as a pan head screw.
FIG. 12 shows the regulating body 50 of the regulating member 5 shown in FIGS. 10 and 11, where (A) is a front view and (B) is a bottom view.
The regulating body 50 is a metal fitting having an approximately L-shaped cross section formed by bending a metal plate, and comprises a rectangular plate-shaped base 52 that is attached to the underside of the base 42, and a rectangular plate-shaped regulating portion 51 that extends downward from the edge of the base 52.
The base portion 52 is formed with a female screw hole 52 a that can be threaded with the male screw of the fastening member 55 .

FIG. 13 is a cross-sectional view taken along line AA in FIG.
The restricting body 50 is attached to the attachment portion 41 of the cover body 4 by threading the male screw of a fastening member 55 inserted from above the base portion 42 into the female screw hole 52 a of the base portion 52 .
The restricting body 50 is formed so that, when attached between the support portions 43, its restricting portion 51 is positioned to cross each groove portion 44. In other words, the restricting body 50 is provided so that the shaft portion 33 inserted deep into each groove portion 44 is prevented from coming out of the groove portion 44 by being blocked by the restricting portion 51.

The restricting body 50 can be removed from the mounting portion 41 by unscrewing the fastening member 55 from the female screw hole 52a.
FIG. 14 is a view showing a state in which the restricting member 5 is removed from the mounting portion 41 of FIG.
By removing the restricting member 5 from the mounting portion 41, the shaft portions 33 can be pulled out of the grooves 44, and the lid body 4 can be removed from the lid body mounting portion 3. The lid body 4 can also be mounted to the lid body mounting portion 3 by reversing the above procedure.

As shown in Figure 6, when the lid body 4 is attached to the lid body attachment portion 3, the shaft portion 33 inserted into the inside of each groove portion 44 formed in each support portion 43 is prevented from coming out from the inside of each groove portion 44 by the regulating portion 51 of the regulating body 50.
6 is in a state in which the lid 4 is open and the lower part of the columnar body 6 can be inserted into the main body tube 2, and in this state, the fastening member 55 of the restricting member 5 is arranged so that the outer wall portion 30a, which is the wall portion 30 of the lid mounting portion 3, is located axially outward of the head of the fastening member 55. Note that the axial direction refers to the direction in which the male thread of the fastening member 55 faces.
By positioning the fastening member 55 in this manner, it becomes difficult to connect tools such as screwdrivers and wrenches to the head of the fastening member 55 because they are blocked by the wall portion 30, making it more difficult to unscrew the fastening member 55 from the female thread hole 52a.
In the state shown in FIG. 6, the fastening member 55 is entirely housed inside the lid mounting portion 3 .
By positioning the fastening member 55 in this manner, when the sheath tube 1 is embedded and fixed to the installation surface so that the uppermost end of the flange portion 21 is positioned near the installation surface, the entire fastening member 55 is positioned below the installation surface, making it more difficult to unscrew the fastening member 55 from the female thread hole 52 a.
By making it difficult to unscrew the fastening member 55 as described above, it is possible to prevent problems such as the fastening member 55 being unscrewed by tampering or the like and the lid body 4 being removed from the main body tube 2 when the lower part of the columnar body 6 is inserted into the sheath tube 1 that is buried and fixed to the installation surface and set upright.
