Summary of the Invention

Problems to be Solved by the Invention

[0004] Although the camera mounting member described in Patent Document 1 can flexibly select the attachment position of the camera, a dead angle occurs in the shooting range of the camera. Further, when installing a camera directed in another direction to compensate for the dead angle, it is necessary to attach camera mounting members at different heights, and the uniformity of the video is lost.

[0005] The present invention has been made to solve the above problems, and its main object is to provide a camera mounting member that can shoot while suppressing the occurrence of dead angles at the same height when attaching and using a surveillance camera.

Means for Solving the Problems

[0006] The first configuration is a camera mounting member fixed to the tip side of an erected pole, and includes a fixing portion that can be fixed to the tip side of the pole, a protruding portion that protrudes outward from the fixing portion, and a plurality of mounting portions provided around the fixing portion of the protruding portion and capable of mounting a camera on the lower surface of the protruding portion.

[0007] In the first configuration, since a plurality of cameras can be mounted around the pole, it is possible to reduce the blind spots when shooting with the camera.

[0008] The second configuration, in addition to the first configuration, the pole has an internal space continuous in the axial direction, is cylindrical with an opening at the tip side, and the fixing portion allows the wiring passing through the internal space of the pole and drawn out from the opening of the pole to pass through the inside.

[0009] In the second configuration, since the wiring passes through the inside of the camera mounting member, the wiring is not exposed to the outside, and it is possible to suppress damage to the wiring and improve the appearance during installation.

[0010] The third configuration, in addition to the second configuration, a plurality of through holes through which the wiring can pass are provided inside the fixing portion corresponding to each of the mounting portions.

[0011] In the third configuration, since the wiring passing through the through hole can be associated with the camera mounted on the mounting portion, it is possible to suppress mistakes in the connection destinations of the wiring and also suppress the entanglement of the wiring.

[0012] The fourth configuration, in addition to the second or third configuration, the wiring is disposed inside an electric conduit disposed in the internal space of the pole and is led out from the tip side of the electric conduit, The fixing portion can connect the tip side of the electric conduit.

[0013] In the fourth configuration, since the wiring can be introduced into the fixing portion after connecting the electric conduit, the installation can be performed more easily.

[0014] In the fifth configuration, in addition to any one of the first to fourth configurations, the fixing portion is a hollow cylindrical shape that can be externally fitted to the tip side of the pole, and the cylindrical wall is provided with insertion holes through which male screws can penetrate. Around the central axis of the fixing portion, the positions of the insertion holes and the mounting portion are offset.

[0015] In the fifth configuration, even when a camera is attached to the attachment portion, the attachment and detachment operation of the male screw used when attaching the camera attachment member to the pole can be easily performed.

[0016] The sixth configuration further includes an umbrella portion that covers at least the tip side of the pole from above the tip of the pole, in addition to any one of the first to fifth configurations.

[0017] In the sixth configuration, the umbrella portion can suppress the intrusion of rain or the like into the pole.

[0018] The seventh configuration further includes an umbrella portion that covers the entire overhanging portion from above, in addition to any one of the first to fifth configurations, and a continuous internal space extending from the fixing portion to the mounting portion is provided between the overhanging portion and the umbrella portion.

[0019] In the seventh configuration, since the wiring led out from the tip of the pole passes through the internal space between the umbrella portion and the overhanging portion and is connected to the camera, the wiring can be protected from rain or the like. Also, since the wiring is not exposed to the outside, the appearance during installation can be improved.

[0020] The eighth configuration further includes an umbrella portion that covers the entire overhanging portion from above, in addition to any one of the first to fifth configurations. The umbrella portion and the overhanging portion are coupled by screwing in a screw, and the umbrella portion and the overhanging portion are provided with alignment means that are in a fitted state when the screw can be screwed in and not in a fitted state when the screw cannot be screwed in.

[0021] When the entire protruding portion is covered by the umbrella portion, it may not be possible to visually check whether a screw can be screwed in. However, in the eighth configuration, since the alignment means can recognize the state in which the screw can be screwed in, the umbrella portion can be attached more easily.

[0022] The ninth configuration is a camera installation device including a camera mounting member having any one of the first to eighth configurations and a pole to which the camera mounting member can be attached on one end side. The pole has an internal space continuous in the axial direction and a window portion opening on the side surface of the other end side.

[0023] In the ninth configuration, since wiring can be introduced into the internal space of the pole from the window portion at the lower end side, it is possible to more suitably suppress the exposure of the wiring to the outside.

[0024] The tenth configuration is such that, in addition to the ninth configuration, the orientation of at least one of the plurality of mounting portions with respect to the standing pole and the opening direction of the window portion coincide.

[0025] In the tenth configuration, the wiring introduced from the window portion can be led to the camera attached to the mounting portion without being twisted.

[0026] The eleventh configuration is such that, in addition to the ninth or tenth configuration, the inner surface forming the internal space of the pole has a plurality of convex portions continuously formed in the axial direction at intervals in the circumferential direction, and the interval between adjacent convex portions is larger than the width of the convex portion in the circumferential direction.

[0027] In the eleventh configuration, by making the thickness partial, it is possible to obtain sufficient strength while reducing the weight of the pole, and the interval between the convex portions is wide, so that the narrowing of the internal space can be suppressed.

[0028] The 12th configuration is a camera installation structure, in which an overhanging portion that protrudes outward from around the pole is attached to the tip of the erected pole, and a plurality of attachment portions capable of attaching a camera to the lower surface of the overhanging portion are provided surrounding the pole, and the camera is attached to the attachment portion.

[0029] In the 12th configuration, an effect similar to that of the 1st configuration can be obtained.

[0030] The 13th configuration is a camera installation structure, in which an attachment portion capable of attaching a camera is provided on the tip side of the erected hollow cylindrical pole, the tip side of the pole and the attachment portion are covered by an umbrella portion, and the wiring led out from the tip side through the internal space of the pole passes through the space covered by the umbrella portion and is connected to the camera attached to the attachment portion.

[0031] In the 13th configuration, an effect similar to that of the 7th configuration can be obtained.

MODE FOR CARRYING OUT THE INVENTION

[0033] As shown in FIG. 1, the camera mounting member 10 according to the embodiment is used by being attached to the upper end of a standing pole 100, and a plurality of monitoring cameras 110 are attached to the camera mounting member 10. The pole 100 is in a hollow cylindrical shape and is formed of metal or a hard resin. The monitoring camera 110 is wired-connected to a monitoring control system, a power source, etc., and the wiring used for the wired connection passes through the internal space of the pole 100 and is connected to the monitoring camera 110. In the following description, the vertical direction of the standing pole 100 will be described as the vertical direction.

[0034] First, regarding the more specific shape of the pole 100, it will be described with reference to FIGS. 1 to 3. As described above, the pole 100 is in the shape of a hollow cylinder. On the side surface of the lower end side of the pole 100, a window portion 101 is provided, which is an oval opening that penetrates in the thickness direction and is long in the vertical direction. Wiring can be introduced into this window portion 101, and the wiring introduced into the window portion 101 can be led out from the upper end of the pole 100. This window portion 101 may be located underground when the pole is erected, or may be exposed on the ground. The cross-sectional shape of the pole 100 is uniform in the vertical direction. On the inner surface, convex portions 102 protruding inward and concave portions 103 between the convex portions 102 are alternately provided in the circumferential direction, and the convex portions 102 and the concave portions 103 are continuously provided over the entire vertical direction. Also, the circumferential width of the convex portion 102 is formed narrower than the circumferential width of the concave portion 103. The wiring introduced into the opening 101 can be led to the upper end along the concave portion 103 inside the pole 101.

[0035] On the side surface near the upper end of the pole 101, insertion holes 104 are provided that penetrate in the thickness direction and have female threads formed on the inner surface. These insertion holes 104 are provided in two rows in the vertical direction at the locations where the convex portions 102 of the pole are located, and are also provided at positions facing each other in the radial direction. Also, the centers of the insertion holes 104 and the window portion 101 are offset by 45 degrees in the circumferential direction.

[0036] As shown in Fig. 1, the camera mounting member 10 is composed of a pedestal portion 20 and an umbrella portion 40 covering the pedestal portion 20. First, the configuration of the pedestal portion 20 will be described with reference to Figs. 4 to 9. The pedestal portion 20 includes a cylindrical fixing portion 21 and a disk-shaped overhanging portion 31 that shares the same center with the fixing portion 21 and extends outward from the upper edge of the fixing portion 21. The inner diameter of the fixing portion 21 is substantially equal to the outer diameter of the pole 100, and the thickness of the side surface is substantially uniform. The upper end of the fixing portion 21 is partially closed by a substantially disk-shaped upper end wall 22, and two first through holes 23 and second through holes 24, which are substantially circular holes penetrating in the vertical direction, are provided in the upper end wall 22. The centers of the first and second through holes 23 and 24 are located on a virtual circle that shares the center with the fixing portion 21. Further, the first and second through holes 23 and 24 are provided at equal intervals around the central axis of the fixing portion 21. The first through holes 23 are provided symmetrically about the central axis and arranged side by side left and right, and the second through holes are provided symmetrically about the central axis and arranged side by side front and back. Note that the upper end wall 22 and the first and second through holes 23 and 24 can be regarded as components forming a part of the fixing portion 21, or can be regarded as separate components closing a part of the upper end of the fixing portion 21.

[0037] Insertion holes 25 penetrating in the thickness direction are provided on the side surface of the fixing portion 21. Two of these insertion holes 25 are arranged in the vertical direction, and are further provided at positions facing each other in the radial direction. In addition, the insertion holes 25 are provided at positions rotated 45 degrees in the circumferential direction from the centers of the first and second through holes 23 and 24 in a plan view. That is, they are provided at positions shifted in the circumferential direction from the positions where the first and second through holes 23 and 24 are provided.

[0038] Here, the specific shape of the first through hole 23 provided side by side in the left-right direction will be described in detail with reference to Fig. 9. It is assumed that a corrugated tube having concavities and convexities continuously alternating in the longitudinal direction is inserted into the first through hole 23 and used, and wiring is provided inside the corrugated tube. Note that the second through hole 24 provided side by side in the front-back direction is a simple circle.

[0039] The first through-hole 23 is provided, on the central axis side, with a semi-circular arc-shaped protrusion 23a that fits into and abuts against the concave portion of the corrugated tube from the side surface. At the front and rear ends of the protrusion 23a, there are provided elastic pieces 23b that are partially arc-shaped with a diameter slightly larger than that of the protrusion and are elastically deformable. On the front and rear sides of the elastic piece 23b, there are provided gaps 23c respectively, and the elastic piece 23b elastically deforms toward the gap 23c side. On the other hand, the first through-hole 23 opens to reach the inner surface of the fixing portion 21 on the side opposite to the central axis side, and the space thereof is referred to as an expansion space 23d. The method for inserting and fixing the corrugated tube into the first through-hole 23 described above will be described later.

[0040] The upper surface of the overhanging portion 31 constitutes a plane continuous with the upper surface of the upper end wall 22. On the upper surface of the overhanging portion 31, there is provided an annular wall-shaped peripheral wall portion 32 that stands vertically upward. The central axis of the peripheral wall portion 32 is common with the center of the overhanging portion 31, and the thickness of the peripheral wall portion 32 is substantially uniform over the entire circumference. Further, on the outer surface of the peripheral wall portion 32, six ribs 33 that protrude outward are provided at equal intervals. The circumferential thickness of the rib 33 is uniform, and the amount of protrusion outward is uniform over the entire vertical direction. Near the outer edge of the overhanging portion 31, there is provided a circular hole 34 that penetrates in the thickness direction. The centers of these holes 34 are located on a virtual circle that shares the center with the overhanging portion 31, and are also located on a virtual extension line passing through the center of the overhanging portion 31 and each rib 33.

[0041] Inside the peripheral wall portion 32 of the overhanging portion 31, four lead-out holes 35, which are circular holes penetrating in the vertical direction, are provided. The diameters of these four lead-out holes 35 are equal, and the centers of the lead-out holes 35 are located on a virtual circle that shares the center with the overhanging portion 31. Further, the centers of the four lead-out holes 35 are located on a virtual extension line passing through the center of the overhanging portion 31 and the centers of the through-holes 23 and 24. That is, the lead-out holes 35 are provided at equal intervals at positions rotated by 90-degree intervals around the center of the overhanging portion 31.

[0042] Around the upper surface side of each lead-out hole 35, a plurality of upper groove portions 36, which are grooves extending radially from each lead-out hole 35, are provided. Between these upper groove portions 36, a plurality of upper concave portions 37, which are depressions recessed downward so as to spread radially from the center of the lead-out hole 35, are provided. On the other hand, around the lower surface side of each lead-out hole 35, a plurality of lower groove portions 38, which are grooves extending radially from each lead-out hole 35, are provided. Between these lower groove portions 38, a plurality of lower concave portions 39, which are depressions recessed upward so as to spread radially from the center of the lead-out hole 35, are provided. The upper groove portions 36 and the lower groove portions 38, and the upper concave portions 37 and the lower concave portions 39 are provided at positions facing each other in the vertical direction and are formed to have the same depth.

[0043] Subsequently, an umbrella portion 40 that is used by being placed on the pedestal portion 20 will be described with reference to FIGS. 10 and 11. The umbrella portion 40 is in the shape of a partial spherical shell, has an annular shape with its lower end located in the same plane, and the virtual line extending vertically upward from the center of the annulus is the most prominent. Further, the center of the virtual sphere of which the partial spherical shell of the umbrella portion 40 constitutes a part of the outer surface is located below the lower end of the umbrella portion 40. The thickness of the umbrella portion 40 is substantially uniform, and the inner diameter of the annulus at the lower end of the umbrella portion 40 is slightly larger than the diameter of the overhanging portion 31 of the pedestal portion 20.

[0044] On the inner surface of the umbrella portion 40, six protruding portions 41 that protrude inward are provided at equal intervals in the circumferential direction. The bottom surface of this protruding portion 41 is flat and is located on the same horizontal plane. Also, the diameter of the inner circumferential circle of the umbrella portion 40 on that horizontal plane is substantially equal to the outer diameter of the pedestal portion 20. Therefore, when the umbrella portion 40 is placed on the pedestal portion 20, the peripheral edge of the overhanging portion 31 abuts against the inner surface of the umbrella portion 40, and the bottom surface of the protruding portion 41 abuts against the upper surface of the overhanging portion 31. Each protruding portion 41 is provided with a female screw portion 42 that is recessed upward. This female screw portion 42 is provided at a position that coincides with the hole 34 of the overhanging portion 31 when the umbrella portion 40 is placed on the pedestal portion 20.

[0045] Inside the raised portion 41 of the umbrella portion 40, an inner hanging wall portion 43 in the shape of an annular wall that hangs vertically over the entire circumference is provided. The diameter of the outer peripheral surface of this inner hanging wall portion 43 is substantially equal to the inner diameter of the peripheral wall portion 32 of the pedestal portion 20. Also, slightly outside this inner hanging wall portion 43, an outer hanging wall portion 44 in the shape of an annular wall that hangs vertically over the entire circumference is provided with a slight gap from the inner hanging wall portion 43. The inner peripheral surface of this outer hanging wall portion 44 is in the shape of an annular wall that extends vertically upward, and the inner diameter is substantially equal to the outer diameter of the peripheral wall portion 32 of the pedestal portion 20. Since the outer hanging wall portion 44 and the inner hanging wall portion 43 are provided in this way, it can be said that an annular groove-shaped groove portion 45 having a gap substantially equal to the thickness of the peripheral wall portion 32 is formed. Six recessed portions 46 that are recessed outward are provided at equal intervals in the circumferential direction on the outer hanging wall portion 44. The cross-sectional shape of this recessed portion 46 is substantially uniform in the vertical direction, and the width in the circumferential direction is substantially equal to the thickness of the rib 33 provided on the peripheral wall portion 32. Also, in a bottom view, the center of the umbrella portion 40, the female screw portion 42, and the recessed portion 46 are located on the same virtual straight line.

[0046] A connecting member 50 shown in FIG. 12 is attached and used in the second through hole 24 of the pedestal portion 20. The overall shape of the connecting member 50 is substantially cylindrical, and a male screw portion 51 is provided on the upper end side. A cylindrical intermediate cylinder portion 52 is provided at the lower end of the male screw portion 51, and a substantially cylindrical connecting portion 53 is provided at the lower end of the intermediate cylinder portion 52. Locking claws 54 that project inward are provided on the inner surface of the connecting portion 53, and it is possible to connect a wiring pipe that covers the wiring of the monitoring camera 110. The vertical central axes of the male screw portion 51, the intermediate cylinder portion 52, and the connecting portion 53 coincide. Also, the outer diameter of the thread of the male screw portion 51 is slightly smaller than the diameter of the second through hole 24, and the outer diameter of the intermediate cylinder portion 52 is slightly larger than the inner diameter of the second through hole 24.

[0047] The connecting member 50 configured as described above is inserted into the second through hole 24 from below. At this time, although the male screw portion 51 passes through the second through hole 24 and the tip side protrudes from above the upper end wall 22 of the pedestal portion 20, the upper end of the intermediate cylinder portion 52 abuts against the lower surface of the upper end wall 22 of the pedestal portion 20. In this state, by screwing a lock nut 55 having a female screw formed on the inner side onto the male screw portion 51, the attachment of the connecting member 50 to the second through hole 24 is completed. It should be noted that in the state where the connecting member 50 is attached to the second through hole 24, it can also be said that the second through hole 24 and the connecting member 50 cooperate to form a through hole through which wiring can pass.

[0048] As shown in FIG. 13, a substantially cylindrical bushing 60 is attached and used in the lead-out hole 35 of the pedestal portion 20. The upper and lower ends of this bushing 60 are widened in a flange shape, and it is attached by abutting the flange-shaped portions against the peripheries of the upper and lower ends of the lead-out hole 35 so as to sandwich them.

[0049] Subsequently, the procedure for attaching the pole 100 and the surveillance camera 110 to the camera attachment member 10 described above will be described with reference to FIG. 13. It should be noted that the procedure of the attachment method in the following description is merely an example, and the order can be changed as appropriate.

[0050] First, the fixing portion 21 of the pedestal 20 is externally fitted to the tip of the pole 100, and wiring is introduced into the pole 100 from the window portion 101 and led out from the tip of the pole 100. At this time, if the wiring is not covered by a wiring pipe or the like, the wiring is passed directly through the inside of the connecting member 50 and led out from the upper end of the male screw portion 51. Also, the connecting member 50 may be attached only to a part of the second through hole 24. In that case, the wiring is passed through the second through hole 24 where the connecting member 50 is not attached and led out from the upper end of the through hole 23. On the other hand, when the wiring is covered by a wiring pipe, after fitting the upper end of the wiring pipe to the connecting portion 53 of the connecting member 50, the wiring is passed through the inside of the connecting member 50 and led out from the upper end of the male screw portion 51.

[0051] Also, when using a corrugated pipe (corrugated tube) as the wiring pipe, the first through-holes 23 arranged side by side left and right are used instead of the connecting member 50 attached to the second through-hole 24. The method of inserting and fixing the corrugated pipe into the first through-hole 23 will be described with reference to FIGS. 14 and 15. First, as shown in FIG. 14, the convex portion 102 of the pole 100 is positioned before and after the expansion space 23d of the first through-hole 23, and in this state, the corrugated pipe is passed through the first through-hole 23. At this time, since the expansion space 23d is not narrowed by the convex portion 102, the corrugated pipe can easily pass through the first through-hole 23. After the corrugated pipe passes through the first through-hole 23, the camera mounting member 10 is rotated (22.5 degrees in this embodiment) around the axis of the pole 100. At this time, the convex portion 102 will be located within the expansion space 23d, and the corrugated pipe will be pressed toward the central axis side. As a result, the protrusion 23a fits into the concave portion of the corrugated pipe, and the elastic piece 23b functions as a surface along the outer surface of the convex portion of the corrugated pipe, restricting the up and down movement of the corrugated pipe. It should be noted that regarding the state where the corrugated pipe is passing through the first through-hole 23, it can also be said that the first through-hole 23 and the corrugated pipe cooperate to form a through-hole through which the wiring can pass.

[0052] If the wiring is led out as described above, a screw is inserted through the insertion hole 25 of the fixing portion 21 and screwed into the insertion hole 104 of the pole 100 to fix the pedestal portion 20 to the tip of the pole 100. At this time, as described above, the insertion hole 25 of the fixing portion 21 and the first and second through-holes 23 and 24 are offset by 45 degrees around the axis, and the insertion hole 104 of the pole 100 and the window portion 101 are also offset by 45 degrees around the axis. Therefore, either the first or second through-holes 23 and 24 and the window portion 100 of the pole 100 are facing in the same direction around the axis.

[0053] Subsequently, the monitoring camera 110 is attached to the extraction hole 35 of the pedestal portion 20. At this time, the monitoring camera 110 is brought into contact with the bushing 60 from below, and is fixed by screwing a screw or the like into the lower groove portion 38 and / or the lower concave portion 39 around the extraction hole 35. At this time, it can be said that the lower groove portion 38 and / or the lower concave portion 39 function as an attachment portion for attaching the monitoring camera 110, and it can also be said that the extraction hole 35 cooperates with the lower groove portion 38 and / or the lower concave portion 39 to function as an attachment portion for attaching the monitoring camera 110. Incidentally, the pedestal 20 may be attached to the tip of the pole with the monitoring camera 110 attached to the pedestal portion 20 in advance. Also in this case, since the position of the insertion hole 25 and the positions of the extraction hole 35 and the monitoring camera 110 are in a displaced positional relationship around the central axis of the fixing portion 21, there is no interference with the monitoring camera 110 when inserting the screw.

[0054] With the monitoring camera 110 attached to the pedestal 20 and the pedestal 20 fixed to the tip of the pole 100, the wiring connection to the monitoring camera 110 is performed. At this time, the wiring that has passed through the second through hole 24 located in the front is passed through the extraction hole 35 located in the front and pulled out under the overhanging portion 31, and is connected to the monitoring camera 110 attached to the lower groove portion 38 and / or the lower concave portion 39 around the extraction hole 35. Similarly for each of the left, right, and rear directions, the wiring that has passed through the first and second through holes 23 and 24 is connected to the monitoring camera 110 attached to the extraction hole 35. That is, the wiring that has passed through the corresponding first and second through holes 23 is connected to each monitoring camera 110.

[0055] When the wiring connection is completed as described above, the pedestal portion 20 is covered with the umbrella portion 40. At this time, since the position of the rib 33 and the like are shielded by the umbrella portion 40 and cannot be visually observed, the umbrella portion 40 is covered with a rough alignment. If the umbrella portion 40 is rotated around the central axis while slightly pressing it from above in this state, the rib 33 and the recess 46 function as positioning means, and when the position of the rib 33 and the position of the recess 46 coincide, the upper end side of the peripheral wall portion 32 fits into the groove portion 45, and the rib 33 fits into the recess 46, and the relative rotation between the pedestal portion 20 and the umbrella portion 40 is restricted. At this time, since the position of the hole 34 and the position of the female screw portion 42 also coincide, by inserting a screw from below into the hole 34 and screwing it into the female screw portion 42, the fixing of the umbrella portion 40 to the pedestal portion 20 is completed. It should be noted that the internal space formed by the umbrella portion 40 and the pedestal portion 20 will have the wiring located therein, and it can be said that a continuous space from the first and second through holes 23, 24 through which the wiring can pass to the lead-out hole 35 is formed.

[0056] With the above configuration, the camera mounting member 10 according to the present embodiment has the following effects.

[0057] · Since a plurality of cameras 110 can be mounted at the same height around the pole 100, it is possible to reduce the dead angle when shooting with the camera 100.

[0058] · Since the wiring passes through the internal spaces of the camera mounting member 10 and the pole 100, the wiring is not exposed to the outside, and it is possible to suppress damage to the wiring and improve the appearance during installation.

[0059] · Since the first and second through holes 23, 24 and the lead-out hole 35 are provided one by one around the front, rear, left, and right of the pole 100, it is possible to associate the wiring that has passed through the first and second through holes 23, 24 with the camera 110 attached to the lead-out hole 35, suppress mistakes in the connection destination of the wiring, and suppress entanglement of the wiring.

[0060] · Since the position of the lead-out hole 35 and the position of the insertion hole 25 of the fixing portion 21 are displaced around the axis, even when the camera 110 is attached to the lead-out hole 35, the screw attachment / detachment operation can be easily performed.

[0061] · Since it is provided with the umbrella portion 40, it is possible to suppress the intrusion of rain or the like into the inside of the pole 100.

[0062] · By aligning the rib 33 of the pedestal portion 20 and the recess 46 of the umbrella portion 40, it is possible to recognize the state in which the screw can be screwed in, so that the umbrella portion 40 can be attached more easily.

[0063] · Since the wiring can be introduced into the internal space of the pole 100 from the window portion 101 on the lower end side of the pole 100, the range of the wiring exposed to the outside can be further reduced.

[0064] · Since the opening direction of the window portion 101 and the direction around the axis of one lead-out hole 35 are the same, the wiring introduced from the window portion 101 can be led to the camera 110 attached to the lead-out hole 35 without being twisted.

[0065] · Since the convex portion 102 extending in the axial direction is formed inside the pole 100, the strength of the pole 100 can be improved. Further, since the wiring introduced into the internal space can be arranged along the concave portion 103 between the convex portions 102, the twisting of the wiring in the internal space of the pole 100 can be preferably suppressed.

[0066] <Modification Example> · In the embodiment, the fixing portion 21 of the pedestal portion 20 is externally fitted to the upper end of the pole 100, but the outer diameter of the fixing portion 21 may be made substantially equal to the inner diameter of the pole 100, and the fixing portion 21 may be fitted into the inside of the tip side of the pole 100.

[0067] · In the embodiment, the pole 100 is formed in a hollow cylindrical shape and the wiring passes through the inside thereof, but the wiring may be arranged along the outer surface of the pole 100 and led to the camera 110 attached to the lead-out hole 35.

[0068] ·In the embodiment, the pedestal portion 20 is disk-shaped, but it can be changed to various shapes such as elliptical or polygonal. Further, the fixing portion 21 does not have to be provided at the center of the pedestal portion 20, and it is sufficient that the overhanging portion 31 extends outward from around the upper end of the fixing portion 21.

[0069] ·The number of the through holes 23, 24 and the lead-out holes 35 can be variously changed, and the number of the lead-out holes 35 may be made larger than the number of the through holes 23, 24. Even in this case, by bringing the position of one through hole 23, 24 close to a plurality of lead-out holes 35 and making the through holes 23, 24 and the lead-out holes 35 correspond to each other, the effects similar to those of the embodiment can be obtained.

[0070] ·In the embodiment, two first through holes 23 into which the corrugated tube is inserted are provided side by side left and right, and two second through holes 24 to which the connecting member 50 can be attached are provided side by side front and back. However, the number and arrangement of these can also be appropriately changed. Further, all the through holes may be the first through holes 23, or all the through holes may be the second through holes 24.

[0071] ·Instead of providing the through holes 23, 24, an opening may be provided on the side surface near the upper end of the pole 100, and the wiring that has passed through the inside of the pole may be led out from the opening and connected to the camera 110.

[0072] ·In the embodiment, the wiring that has passed through the through hole 23 reaches the lead-out hole 35. However, it is also possible to only attach the camera 110 so as to correspond to the lead-out hole 35, provide an opening between the through hole 23 and the lead-out hole 35, and connect the wiring led out from the opening to the camera 110. Further, in this case, since the wiring is not led out from the center of the lower groove portion 38 and the lower concave portion 39, the lead-out hole 35 is not provided at that position, and the opening between the through holes 23, 24 and the lower groove portion 38 and the lower concave portion 39 may be used as the lead-out hole by the same name.

[0073] ·In the embodiment, an example is shown in which the camera 110 is attached to all of the four extraction holes 35. However, there may be extraction holes 35 to which the camera 110 is not attached as necessary. In this case, if the extraction holes 35 are blocked, it is possible to suppress the intrusion of dust or the like into the internal space of the camera attachment member 10.

[0074] ·The umbrella part 40 is not necessarily required, and it may cover a part of the overhanging part 31 or may cover only the upper end of the pole 100. Further, even if the umbrella part 40 can be attached to the pedestal part 20, especially when used indoors, it may be used without attaching the umbrella part 40.

[0075] ·Regarding the window part 101, it may be provided from the side surface to the lower end of the pole 100, or the opening at the lower end of the cylindrical pole 100 may function as the window part 101, and wiring may be inserted from the opening at the lower end.

[0076] <Supplementary Note> Summarizing the pole 100 according to the embodiment, it can be described as follows.

[0077] <Supplementary Note 1> A pole having one end side erected upward, having an internal space continuous in the axial direction, a window portion, which is an opening that penetrates in the thickness direction and extends in the axial direction, is provided on the side surface of the other end side, a plurality of convex portions continuous in the axial direction are provided at intervals in the circumferential direction on the inner surface forming the internal space, a female screw that penetrates the portion where the convex portion is formed is formed in the middle in the axial direction, a pole.

[0078] In Supplementary Note 1, since it is partially thick, it is possible to obtain sufficient strength while reducing the weight of the pole 100. Further, since the length of the female screw can also be ensured, the stability when a male screw is screwed into the female screw can be improved.

[0079] Also, regarding the structure in which a corrugated pipe is inserted into and connected to the first through hole 23, if the first through hole 23 is referred to as the inner space into which the corrugated pipe is inserted, the fixing portion 21 is referred to as a connection base having an inner space into which the corrugated pipe is inserted, the pole 100 is referred to as a moving body that can move along the outer peripheral direction of the corrugated pipe, and the convex portion 102 on the inner surface of the pole 100 is referred to as a contact surface that contacts the outer surface of the corrugated pipe, it can be summarized as follows.

[0080] <Appendix 2> It consists of a connection base having an inner space into which the corrugated pipe is inserted and a moving body that moves along a part of the outer peripheral direction of the corrugated pipe inserted into the inner space. In the inner space, a protrusion is provided that can enter the recess of the corrugated pipe and restrict the axial movement of the corrugated pipe. On the inner surface of the inner space on the side opposite to the protrusion, an expansion space for expanding the inner space is provided. The moving body has a contact surface that contacts the outer surface of the corrugated pipe, and the contact surface can select a direction in which the protrusion enters the recess of the corrugated pipe and a direction in which the corrugated pipe can move toward the expansion space side. This is the connection structure of the corrugated pipe.

[0081] When connecting a corrugated pipe, generally, since the unevenness on the outer surface of the corrugated pipe and the protrusion that fits into the recess are elastically deformed and pushed in, there is a risk of damage to the corrugated pipe or the protrusion. In this regard, in the configuration of Appendix 2, when connecting the corrugated pipe, since the moving body's contact surface can select a state where the protrusion enters the recess and a state where it can be detached from the recess, it can be inserted more easily when inserting the corrugated pipe, and stronger fixing can be achieved when fixing with the protrusion.
