[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-203289 Summary of the Invention [Problem to be solved by the invention]
[0005] The bollard support shown in Patent Document 1 is designed so that the cover can be easily replaced if it is deformed or damaged by being run over by a vehicle or the like, but there is a possibility that the cover could be removed by vandals when the bollard support is installed and in use.
[0006] The present invention provides a sheath tube that can prevent tampering with the removal of a lid, and an installation structure for a columnar body using the sheath tube. [Means for solving the problem]
[0007] In order to achieve the above object, the present invention has the following configuration. That is, the sleeve pipe according to the present invention is a sleeve pipe that is embedded and fixed in an installation surface to support a columnar body such as a car stopper, and is provided with a cylindrical main body tube with a bottom and an opening at the top, and a lid body that is pivotally supported on the shaft of the main body tube and opens and closes the opening, and a fastening member is attached to the lid body, and the fastening of the fastening member can be released. and remove the fastening member axially outward. The cover can be removed from the shaft by the fastening member. When the cover closes the opening of the main body tube, The axially outer side is directed upward. The cover is detachable, and a columnar body is insertable into the main body tube. The axially outer side faces a wall portion provided at the upper part of the main body tube. The device is characterized in that it is provided so as to be unable to be removed from the lid body.
[0008] The sleeve tube according to the present invention includes a bottomed, cylindrical main tube having an opening at the top and a lid pivotally supported on the shaft of the main tube for opening and closing the opening of the main tube. By closing the opening with the lid, the intrusion of dust and other foreign matter into 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 contacting a column supported by the sleeve tube when the sleeve tube is installed on an installation surface, the fastening member can be released to remove the lid from the shaft and easily replaced. Furthermore, since the fastening member is in a state where a column can be inserted into the main tube, removing the lid from the sleeve tube when a column such as a car stopper is installed thereon is extremely difficult, thereby preventing the lid from being removed by tampering or the like.
[0009] Furthermore, if a lid mounting section having a wall section is formed on the top of the main body tube, and the shaft section is placed 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 inside of the main body tube, then in a sheath 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, making it possible to effectively make the fastening member unremovable, which is preferable.
[0010] Furthermore, if the uppermost end of the wall portion of the lid mounting portion is formed to be positioned near the installation surface, and the entire fastening member is positioned below the uppermost end of the wall portion when a pillar-shaped body can be inserted inside the main body tube, in a sheath pipe used to install a pillar-shaped body such as a car stopper, the wall portion or installation surface will prevent the use of a tool to release the fastening of the fastening member, making it possible to effectively make the fastening member unremovable, which is preferable.
[0011] Furthermore, if the sheath pipe is buried and fixed in the installation surface and supported by a pillar-shaped body, it becomes extremely difficult to remove the lid from the sheath pipe that is used to install a pillar-shaped body such as a car stopper, thereby preventing the lid from being removed by tampering, etc. [Effects of the Invention]
[0012] According to the installation structure for the sheath tube and columnar body of the present invention, problems such as the lid being removed from the sheath tube by tampering or the like can be prevented when a columnar body such as a car stopper is installed and in use.

[0016] The lid attachment portion 3 is provided in a substantially box-like shape and is configured with a wall portion 30 connected to the cylindrical wall 20 . 5 is an enlarged view of the upper part of FIG. 2, and FIG. 6 is a cross-sectional view taken along the line AA in FIG. The wall portion 30 comprises plate-shaped side wall portions 30b arranged at intervals around the circumferential direction of the main body tube 20, and an outer wall portion 30a formed to connect to the edges of each side wall portion 30b, and the shaft portion 33 is arranged in a hollow portion 34 provided inside the outer wall portion 30a. The shaft portion 33 is formed by the male thread portion of a screw member, and the shaft portion 33 is provided by threading a nut onto the tip of the male thread portion that is inserted into each side wall portion 30b so as to penetrate the cover body mounting portion 3. The lid body mounting portion 3 is provided with the uppermost ends of the outer wall portion 30a and each side wall portion 30b constituting it at a height position that is approximately the same as the uppermost end of the flange portion 21 of the main body tube 20, and the shaft portion 33 is positioned below that.
[0017] The lid body 4 includes a substantially disk-shaped lid portion 40 and an attachment portion 41 formed so as to protrude radially outward from the edge of the lid portion 40 . 8 is a front view showing the lid body 4 of the sleeve tube 1 of FIG. 1, FIG. 9 is a plan view of FIG. 8, FIG. 10 is an enlarged view of the attachment portion 41 of the lid body 4 of FIG. 9, and FIG. 11 is a view showing an outline of the shape of the attachment portion of FIG. 10 in a side view. 8 to 11 show a state in which the restricting member 5 is attached to the cover 4. In FIG. 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.
[0018] 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 .
[0019] 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 52a that can be threaded with the male screw of the fastening member 55 .
[0020] FIG. 13 is a cross-sectional view taken along the line AA in FIG. The regulation body 50 is attached to the attachment portion 41 of the lid 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.
[0021] The restriction body 50 can be removed from the attachment 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.
[0022] 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 part 30a, which is the wall part 30 of the lid body attachment part 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 a screwdriver or wrench 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. 6, the fastening member 55 is entirely housed inside the lid body attachment portion 3. In the state shown in FIG. By arranging the fastening member 55 in this manner, when the sheath pipe 1 is embedded and fixed to the installation surface so that the uppermost end of the flange portion 21 is located near the installation surface, the entire fastening member 55 is located below the installation surface, making it more difficult to unscrew the fastening member 55 from the female thread hole 52a. 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.
[0023] FIG. 7 is a view showing a state in which the cover 4 of FIG. 5 is closed. The lid body 4 rotates around the shaft portion 33, and the lid portion 40 abuts on the flange portion 21 of the main body tube 2, closing the tube wall 20 and covering almost the entire upper part of the inner surface thereof. When the lid 4 is closed, the fastening member 55 of the restricting member 5 is positioned so that the wall portion 30 of the lid attachment portion 3 is not positioned axially outside the head portion of the fastening member 55. By arranging the fastening member 55 in this manner, it is possible to easily connect a tool such as a screwdriver or a wrench to the head and unscrew the fastening member 55 from the female thread hole 52a. Furthermore, in the state shown in FIG. 7, when the sheath pipe 1 is embedded and fixed to the installation surface so that the uppermost end of the flange portion 21 is located near the installation surface, the head of the fastening member 55 is located above the installation surface, which makes it easier to unscrew the fastening member 55 from the female thread hole 52a. That is, with the lid body 4 closed without erecting the columnar body 6 on the sheath pipe 1 embedded and fixed to the installation surface, the fastening member 55 can be unscrewed, the mounting portion 41 can be removed from the shaft portion 33, and the lid body 4 can be removed from the main body tube 2. By providing it in this manner, if the lid body 4 is damaged, the replacement work of removing the lid body 4 from the main body tube 2 and attaching a new lid body 4 can be easily performed.

The engaging portion 62 is connected to the outer surface of the column portion 61 via a connecting portion 63, and is disposed above the lowermost end of the column portion 61 with a space therebetween.
[0025] 17 is an enlarged view showing the vicinity of the engaging portion 62 of the columnar body 6 in FIG. 15, and FIG. 18 is a right side view of FIG. The connecting portion 63 includes a flat horizontal portion 63a that protrudes radially outward from the outer surface of the column portion 61, and a flat vertical portion 63b that extends upward from the end of the horizontal portion 63a. The engaging portion 62 has a flat plate shape that protrudes radially outward from the upper end of the vertical portion 63b, and is formed as a vertical plate-like protruding piece that is oriented vertically. The engaging portion 62 has a circular through-hole 62a formed near the protruding tip. The engaging portion 62, and the horizontal portion 63a and vertical portion 63b of the connecting portion 63 are formed by bending a single metal plate.
[0026] FIG. 19 is a diagram showing the state in which the columnar body 6 of FIG. 15 is inserted into the sheath pipe 1 that is embedded and fixed in the installation surface G. In the sleeve pipe 1 shown in FIG. 19, only the portion of the main body tube 2 near the uppermost end of the flange portion 21 is exposed above the installation surface G, and the lower portion thereof is buried and fixed. The columnar body 6 is inserted into the inside of the cylindrical wall 20 until the lower end of the column portion 61 abuts against the upper surface of the bottom plate 25, and the outer surface 61a of the inserted portion abuts against the inner surface 20a of the cylindrical wall 20 and is supported. The engagement portion 62 of the columnar body 6 is positioned at a position corresponding to the through hole 40a of the lid portion 40 in the open state, and the engagement portion 62 can be inserted into the through hole 40a by rotating the lid portion 40 around the shaft portion 33 as an axis.
[0027] FIG. 20 is a diagram showing the state in which the cover body C is attached to the columnar body 6 of FIG. 20 has a padlock R attached to the through-hole 62a of the engagement portion 62 inserted into the through-hole 40a of the lid 4. The engagement portion 62 of the columnar body 6 is engaged with the lid 40 to prevent the columnar body 6 from coming off the main body 2. Above the installation surface G, a cover body C is attached to the outside of the columnar body 6. The cover body C is made of an elastic material and is provided in a cylindrical shape having an inner diameter corresponding to the outer diameter of the column portion 51. The cover body C is attached so that a part of its lower end is inserted between the outer surface 60a and the vertical portion 63b of the pillar portion 61, and is fixed to the pillar portion 61 by a screw member B attached from the outside. The pillar body 6 to which the cover body C is attached is provided so as to be suitable for use as a car stopper.
[0028] The sleeve pipe 1 shown in FIG. 20 may be damaged, such as the lid portion 40 being deformed, when a vehicle or the like comes into contact with the pillar-shaped body 6 used as a car stopper. In such a case, the cover body C and the columnar body 6 can be removed in the reverse order to the above, and the lid body 4 can be rotated to the closed position, whereby the fastening member 55 can be removed, and the lid body 4 can be removed from the main body tube 2 and replaced.
