  In the invention disclosed in Patent Document 1, there is a problem that when the wind is received, the support column is easily bent, and as a result, the camera shakes and is out of focus, and a clear image cannot be obtained. Further, in the invention disclosed in Patent Document 2, since the structure is used to prevent the column main body from being bent, if there is no structure near the object to be photographed, the column can be prevented from bending. There was a problem that it was not possible.

  The present invention has been made in response to such a conventional situation, and provides a support column that is difficult to bend even when subjected to wind, and that is difficult to cause large shaking at the upper end portion where a camera or the like is mounted. Objective.

  In order to achieve the above object, the first aspect of the present invention is to provide a column main body in which a sensor and a camera are installed at the tip, a fixture attached to the column main body, and a fixture orthogonal to the longitudinal direction of the column main body. A rod-shaped rope holding tool whose base end is fixed to, a connecting tool that is attached to the column main body at a predetermined interval from the fixing tool, and a rope that is stretched between the connecting tool and the tip of the rope holding tool. , Provided.

  In the strut with the above structure, when it receives wind, a force to bend the strut body in a predetermined direction is generated, but the part between the fixing tool and the connecting tool is opposite to the place where the rope is installed. The force to bend the column main body in the direction is relaxed by the tension of the rope. That is, in 1st invention, it has the effect | action that it becomes difficult to bend with respect to a predetermined | prescribed direction about the part between a fixing tool and a connection tool among support | pillar main bodies. In addition, since this invention is not the structure which suppresses the bending | deflection of a support | pillar main body using a structure, even when there is no structure near the place to be used, the said effect | action is exhibited without any trouble.

Moreover, 2nd invention is 1st invention. WHEREIN: Between the front-end | tip of each of several rope holders and these rope holders which are radially installed with respect to a support | pillar main body at equiangular intervals, and a coupling tool. It is characterized by comprising a plurality of ropes each stretched.

In the strut having such a structure, the force for bending the strut body at each of the plurality of locations where the rope is installed is alleviated by the tension of the rope. That is, in the present invention, since there are a plurality of column main body orientations for effectively exhibiting the action of the first invention, the action is more reliably exhibited.

According to a third invention, in the first invention or the second invention, the rope holder includes a first round bar formed at least partially in a cylindrical shape, and an inner peripheral surface of the first round bar. A male threaded portion that is screwed with the formed female threaded portion is composed of a second round bar formed on the outer peripheral surface, and a rope is attached to one end of either the first round bar or the second round bar. It is characterized by this.
In the strut having such a structure, in addition to the action of the first invention or the second invention, when the second round bar is rotated with respect to the first round bar, the second round bar moves back and forth. It has the effect | action that it moves to a direction and the full length of a rope holder changes.

According to a fourth aspect of the present invention, in any one of the first to third aspects, the rope holder is attached to the rod-like body to which the rope is attached at one end, the fixture, and the other end of the rod-like body. A connecting member that is pivotably connected about an axis orthogonal to the longitudinal direction, and a rotational restraint that holds the rod-like body in a state in which the longitudinal direction of the connecting member coincides with the connecting member by restraining the pivoting of the rod-like body. And means.
In the strut having such a structure, in addition to the function of any one of the first to third inventions, the function of suppressing the rotation of the rod-shaped body by the rotation suppressing means is released, and When the rod-shaped body is rotated with respect to the connecting member so as to be parallel to the longitudinal direction, the rope holder has an effect that the rope holder is not bulky. Moreover, it has the effect | action that a rod-shaped body is hold | maintained by the rotation suppression means so that it may not rotate carelessly from the state which made the connection member and the mutual longitudinal direction correspond.

In a fifth aspect based on the fourth aspect, in the fourth aspect, the rotation restraining means is configured so that at least a part of the rod-shaped body and the connecting member can be arranged inside at the same time in a state where the longitudinal directions of the rod-shaped body and the connecting member coincide with each other. It consists of a cylindrical body slidably inserted along the longitudinal direction.
The support having the above structure has an effect that the function of the rotation suppressing means exhibited in the fourth invention is realized by a simple structure.

A sixth invention is characterized in that, in the fifth invention, provided with a biasing means which is installed on the rod-like body and biases the cylindrical body toward the connecting member along the longitudinal direction.
In the strut having such a structure, in addition to the action of the fifth invention, when at least a part of the rod-like body and the connecting member are simultaneously arranged inside the cylinder body, the state in which the longitudinal directions of the rod body and the connecting member coincide with each other is urged Since it is reliably maintained by the means, it has an effect that the rod-shaped body does not rotate unintentionally.

7th invention is equipped with the cyclic | annular member centering on a support | pillar main body and orthogonally crossing the longitudinal direction in 2nd invention, The front-end | tips of several rope holders pass through this cyclic | annular member Are connected to each other.
In addition to the effect of the second invention, the strut having such a structure has an effect that the rope holder is protected by an annular member so that the rope holder is not damaged even if the strut body falls down.

According to an eighth invention, in any one of the first to seventh inventions, the connector comprises a first connector and a second connector arranged above and below the fixture, respectively, and the rope Is characterized in that both ends are respectively connected to the column main body via the first connecting tool and the second connecting tool, and the middle part thereof is held by the tip of the rope holder.
In the column having such a structure, the portion between the first connector and the fixture and the portion between the second connector and the fixture in the column body is difficult to bend in a predetermined direction. That is, in the present invention, in addition to the operations of the first to seventh inventions, the range in which the column main body is difficult to bend in a predetermined direction is the case of any of the first to seventh inventions. It has the effect of becoming wider.
In any one of the first to seventh inventions, if the interval between the connector and the fixture is set to be the same as the interval between the first connector and the second connector in the present invention, The effect | action that a support | pillar main body becomes difficult to bend about the same range as a case is exhibited. However, in this case, since the rope holder is about twice as long as the case of the present invention, the rope holder may be bulky and obstructive during installation and carrying.

In a ninth aspect based on the first aspect, instead of providing the rope holder and the fixture, the ninth aspect has a circular shape or a regular polygonal shape, and a plurality of through holes are formed around the insertion hole of the column main body provided at the center. Provided in the vicinity of the peripheral edge at equiangular intervals, and provided with a plate-like member arranged so as to be orthogonal to the column main body inserted through the insertion hole, the rope is between the coupling tool and the tip of the rope holder Instead of being stretched, the both ends are respectively connected to the column main body and the middle part is inserted through the through hole.
In the strut having such a structure, in addition to the effect of the first invention, the effect that it is difficult to break even when the strut body falls down is further exhibited as compared with the case of using the rope holder and the annular member. .

  As described above, according to the first invention, since the camera or the like attached to the tip of the column main body is difficult to shake, a clear image can be obtained by the camera or the like. In addition, since such an effect is similarly exerted even in a place where there is no structure nearby, the present invention has no restrictions on the installation place and is excellent in versatility.

  In the first invention, since the swing of the upper end of the column main body becomes the smallest when the part where the rope is installed is directed in the direction in which the wind blows, when the wind direction is changed after the column main body is installed, It is necessary to readjust the orientation of the column body. On the other hand, in the second invention, since there are a plurality of column main body orientations that are most effective, even if the wind direction is changed after the column main body is installed, work for adjusting the column main body direction again occurs. Less likely. Therefore, installation work can be performed easily.

  According to the third invention, in addition to the effects of the first invention or the second invention, the magnitude of the rope tension can be easily adjusted by changing the total length of the rope holder, and the installation of the rope There is an effect that it is possible to improve the work efficiency when removing or removing.

  In the fourth invention, when the rod-shaped body is rotated with respect to the connecting member so as to be parallel to the longitudinal direction of the column main body, the rope holder is not bulky, so the first invention to the third invention. In addition to the effect of any one of the inventions, there is an effect that it is easy to carry and store. In addition, the present invention is excellent in safety because there is no risk that the rod-like body will rotate carelessly during use.

  The column of the present invention will be specifically described with reference to FIGS. In the following description, the expressions “upper end” and “lower end” are used assuming that the column main body is used in a state of being installed in parallel with the vertical direction. However, the column of the present invention is not limited to the case where the column main body is installed in parallel with the vertical direction, and the operation described below even when the column main body is installed and used in parallel with an arbitrary direction. The effect is exhibited as well.

FIG. 1 is a front view showing an example of the appearance of a support according to the present invention, and FIG. 2 is an enlarged perspective view of a part thereof.
As shown in FIG. 1, a column 1a according to the present invention includes a column body 2 composed of a plurality of pipes 4 connected to each other via a connector 3 so as to form a straight line in the vertical direction, and a column installed on the ground or the like. A tripod 5 that supports the lower end 2b of the main body 2 and a top end 2a of the column main body 2 are provided so that the main body 2 is parallel to the vertical direction, and a screw shaft portion (not shown) is provided at the center. The camera fixture 6 projecting toward the projector, the fixture 7a attached so as not to move in the longitudinal direction with respect to the column main body 2, and the three rope holders fixed to the column main body 2 via the fixture 7a Via a pair of coupling tools 7b and 7b, which are respectively arranged in the vertical direction across the fixture 8 and the fixture 7a, and are attached to the column main body 2 so as not to move in the longitudinal direction, and via the coupling tools 7b and 7b. Both ends are connected to the column body 2 respectively. It has a structure with three ropes 9.

In this embodiment, the pipe 4 is a cylindrical body. However, the present invention is not limited to this, and for example, the pipe 4 may be a rectangular tube body. Further, the column main body 2 may be configured by a solid rod-like body instead of the pipe 4.
Furthermore, in this embodiment, the column main body 2 is configured by a plurality of pipes 4 connected via the connection tool 3, but the column main body 2 is not limited to such a structure, and a plurality of different outer diameters are used. It can be made of a pipe, and the entire structure can be expanded and contracted by inserting a pipe having a small outer diameter into a pipe having a large outer diameter.
Moreover, it is good also as a structure which can attach not only a camera but various sensors to the upper end part of the support | pillar main body 2. FIG. Furthermore, the number of the connecting tool 3, the fixing tool 7a, the connecting tool 7b and the number of the pipes 4 and the rope holding tool 8 are not limited to those shown in this embodiment, and can be changed as appropriate.

The tripod 5 includes a pipe 10 formed so as to be able to hold the lower end portion 2b of the column main body 2 inserted from above, a base 11 on which the pipe 10 can be moved up and down, and a horizontal axis with respect to the base 11 Are provided so as to be pivotable about the center, and are provided with three legs 12 whose substantially central portions in the longitudinal direction are respectively connected to the pipe 10 via the connecting rod 13. 10 and the side surface of the leg 12 are respectively connected so as to be rotatable.
In addition, it is good also as a structure which supports the support | pillar main body 2 with support tools other than the tripod 5. FIG.

As shown in FIG. 2, the three rope holders 8 are rod-like bodies that are orthogonal to the central axis of the column main body 2 and are radially arranged at substantially equal angular intervals, and the base ends 8b are the fixtures 7a. It is attached to the side of the. A rope 9 is inserted through the annular body 14 provided at the tip 8a.
That is, the rope 9 is stretched between the fixing tool 7a and the connecting tools 7b and 7b (see FIG. 1) so that the substantially central portion is held by the tip 8a of the rope holding tool 8.

  When the strut 1a having such a structure receives wind, a force for bending the strut body 2 in a predetermined direction is generated. However, since the rope 9 is stretched between the fixing tool 7a and the connecting tool 7b, the force to bend the column main body 2 to the side opposite to the installation location of the rope 9 is alleviated by the tension of the rope 9. . Therefore, in the pillar 1a, when the pillar body 2 receives wind on the side where the rope 9 is installed, at least a portion between the fixing tool 7a and the connecting tool 7b has an effect that it is difficult to bend.

As described above, according to the column 1a, the camera mounted on the upper end 2a of the column main body 2 is difficult to shake, so that a clear image can be obtained by this camera. In addition, in the support | pillar 1a, the three ropes 9 are arrange | positioned radially at substantially equal angular intervals centering | focusing on the support | pillar main body 2, and the above-mentioned effect | action is exhibited with respect to the wind which blows with respect to the support | pillar main body 2 from three directions. Therefore, even when the wind direction changes after the support column body 2 is installed, there is a low possibility that an operation for adjusting the direction of the support column body 2 will occur.
Therefore, installation work can be performed easily. Moreover, since this invention is not the structure which utilizes a structure in order to suppress the bending | deflection of the support | pillar main body 2, there is no restriction | limiting with respect to an installation place, and it is excellent in versatility.

When the interval between the fixture 7a and the connector 7b is increased, the range in which the column main body 2 is difficult to bend due to the above-described action is widened. However, if the distance between the fixing tool 7a and the connecting tool 7b is too long, the rope holding tool 8 also becomes longer, which may cause inconvenience in carrying and restrictions on the installation location.
On the other hand, in the strut 1a having the above structure, the central portion of the rope 9 whose both ends are connected to the connecting tools 7b and 7b arranged in the vertical direction with the fixing tool 7a interposed therebetween is the tip 8a of the rope holding tool 8. Since the structure is held, even if the rope holder 8 is not so long, the column main body 2 has an effect that it is difficult to bend over a wide range. Therefore, there is a low possibility that the work efficiency during transportation and carrying is reduced.

3 and 4 are views for explaining the structure of the rope holder constituting the support shown in FIGS. 1 and 2.
Specifically, FIG. 3A is an external view of a rope holder, and FIG. 3B is a cross-sectional view showing a state in which a cylindrical body is cut along a plane parallel to the axial direction. 3 (c) and 3 (d) are a front view and a plan view, respectively, showing a state where the cylindrical body is removed in FIG. 3 (a), and FIG. 3 (e) is a view in FIG. 3 (d). It is the figure which expanded the edge part by the side to which the connection member was connected partially expanded. In addition, illustration of a coil spring is abbreviate | omitted in FIG.3 (c) and FIG.3 (d).
4 (a) is a view showing a state where the cylinder is removed in FIG. 3 (a), and FIGS. 4 (b) and 4 (c) show the inside of the rope holder in FIG. 3 (a). It is the figure which showed the structure. Note that FIG. 4C corresponds to a view in which the cylindrical body is slid in FIG. 4B to expose the portion where the connecting member is connected to the rod-shaped body.
Further, FIG. 5 (a) is a view showing the internal structure of the stepped bar constituting the rope holder, and FIG. 5 (b) shows the state where the rope holder is attached to the pipe constituting the column body. FIG.

As shown in FIGS. 3 and 4, the rope holder 8 has a stepped rod 15 having small diameter portions 15a and 15f and a large diameter portion 15b and a pair of connecting pieces 16a and 16a so as to protrude in the longitudinal direction. A rod-shaped connecting member 16 provided in the cylinder, a cylindrical body 17 having a small-diameter portion 17a and a large-diameter portion 17b, and a coil spring 18 (see FIG. 4 (a)).
In this embodiment, the stepped rod 15 and the connecting member 16 are columnar or cylindrical, but the present invention is not limited to this. For example, the stepped rod 15 and the connecting member 16 are a prismatic column or a rectangular tube. Also good.

  The stepped bar 15 is provided so that a connecting piece 15c having a shaft hole 15d protrudes in the longitudinal direction at an end portion on the small diameter portion 15a side, and the connecting pieces 16a and 16a of the connecting member 16 are identical to the shaft hole 15. A pair of shaft holes 16b, 16b having an inner diameter of 1 mm are provided so as to communicate with each other (see FIG. 3E). The connecting piece 15c and the connecting pieces 16a and 16a are connected via a shaft body 15 fitted into the shaft hole 15d and the shaft holes 16b and 16b. That is, the connecting member 16 is connected to the stepped bar 15 so as to be swingable about a shaft body 19 installed so as to be orthogonal to the longitudinal direction thereof.

  The cylindrical body 17 is formed such that the small diameter portion 17a can be inserted into the small diameter portion 15a of the stepped rod 15 and the connection member 16, and the coil spring 18 cannot be inserted, and the large diameter portion 17b is formed to be large in size of the stepped rod 15. It is formed so that the diameter portion 15 b and the coil spring 18 can be inserted, and is externally inserted into the stepped rod 15. And the coil spring 18 is formed so that the large diameter part 15b of the stepped bar 15 cannot be inserted.

  The coil spring 18 has both ends of the end surface 15e (see FIG. 3C or 3D) of the large diameter portion 15b of the stepped bar 15 and the end surface 17c of the large diameter portion 17b of the cylindrical body 17 (FIG. 3B). (Refer to FIG. 4 (b) or FIG. 4 (c)). That is, the cylindrical body 17 is urged by the coil spring 18 in the direction in which the large diameter portion 17b is separated from the large diameter portion 15b of the stepped bar 15 (the direction indicated by the arrow X1 in FIG. 4B).

As described above, since the base end 8b of the rope holder 8 is attached to the fixture 7a, when the longitudinal direction of the connecting member 16 and the longitudinal direction of the stepped bar 15 coincide, The end face 17d (see FIG. 3B) is biased by the coil spring 18 to maintain a state where it is flush with the end face 16c of the connecting member 16 (see FIG. 3C or FIG. 3D).
At this time, since the stepped bar 15 and a part of the connecting member 16 are simultaneously disposed inside the small diameter portion 17a with the connecting portion of the stepped bar 15 and the connecting member 16 sandwiched therebetween, the connecting member 16 cannot rotate with respect to the stepped rod 15 (see FIG. 4B).
On the other hand, the direction in which the large diameter portion 17b is brought closer to the large diameter portion 15b of the stepped rod 15 so that the portion where the connection member 16 is coupled to the stepped rod 15 is disposed outside the small diameter portion 17a (FIG. 4C When the cylindrical body 17 is moved against the urging force of the coil spring 18 in the direction indicated by the arrow X2), the connecting member 16 can rotate with respect to the stepped rod 15 (see FIG. 4C). .

As shown in FIG. 5A, the stepped bar 15 includes a cylindrical large-diameter portion 15b having a female screw portion 22a formed on the inner peripheral surface and a small-diameter portion 15a connected to one end, and a female screw portion. A male screw portion 22b that is screwed into 22a comprises a cylindrical small diameter portion 15f formed on the outer peripheral surface. When the small diameter portion 15f is rotated relative to the large diameter portion 15b, the small diameter portion 15f is moved back and forth. It is configured to move in the direction.
That is, the column 1a has a structure in which the entire length of the rope holder 8 can be easily changed by changing the length of the stepped bar 15.

In the strut 1a having such a structure, since the entire length of the rope holder 8 can be easily changed, the magnitude of the tension of the wire 9 can be easily adjusted. Removal and other work can be performed efficiently.
Further, in the column 1 a, the cylinder body 17 functions as a rotation suppressing unit that prevents the stepped bar 15 from being inadvertently rotated, and the coil spring 18 constrains the movement of the cylinder body 17 to maintain the function. Acts as follows. Therefore, the support column 1a is excellent in safety because there is no possibility that the stepped bar 15 rotates carelessly during use.
Further, for example, as shown in FIG. 5B, the column 1a is substantially parallel to the column main body 2 as shown in FIG. When the stepped rod 15 is rotated with respect to the connecting member 16 until it becomes, since the rope holder 8 is not bulky, it is easy to carry and store.

In this embodiment, the coil spring 18 is used as means for urging the cylindrical body 17 in the direction away from the large diameter portion 15b of the stepped bar 15 by the coil spring 18, but the present invention is not limited to such a structure. In the support of the present invention, a spring having a shape other than the coil may be used, or an elastic member such as rubber may be used instead of the spring.
Further, in this embodiment, the cylindrical body 17 is used as means for suppressing the rotation of the stepped bar 15, but the present invention is not limited to this, and the rotation is performed by holding the connecting portion between the stepped bar 15 and the connecting member 16. A clip or the like that suppresses the above can be used instead of the cylindrical body 17. However, in this case, it is necessary to devise the shape of the clip so that the connecting portion between the stepped bar 15 and the connection member 16 can be securely clamped. On the other hand, the cylindrical body 17 shown in the present embodiment has a simple structure, so that the manufacturing cost can be reduced.

FIG. 6 is a front view showing a modified example of the column of this embodiment.
As shown in FIG. 6, in the column 1 b, a connecting tool 7 b disposed below the fixing tool 7 a is attached to the base 11 of the tripod 5. That is, the column 1b has a structure in which the lower end of the rope 9 in the column 1a is connected to the tripod 5 instead of being connected to the column body 2 via the connector 7b.
In the column 1a, when the column main body 2 receives wind, bending may occur if the rigidity between the connecting member 7b and the tripod 5 is low. On the other hand, in the support column 1b, since the force to bend the part caused by the wind is relaxed by the tension of the rope 9, there is an advantage that the part is difficult to bend.

Fig.7 (a) is a front view which shows the external appearance of another form of the support | pillar of this invention, FIG.7 (b) is the top view which expanded the rope holder and annular member in Fig.7 (a), 7 (c) is a diagram showing a modification of FIG. 7 (b). In addition, about the component shown in FIG. 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
As shown in FIGS. 7 (a) and 7 (b), the support column 1c is an annular member that is arranged so as to be centered on the support column body 2 and perpendicular to the longitudinal direction in the support column 1a of the first embodiment. 20, and the tips 8 a of the plurality of rope holders 8 are connected to each other via the annular member 20. The rope 9 is inserted through a through hole 20 a provided in the annular member 20 instead of the annular body 14.
In the support column 1c having such a structure, even if the support column body 2 falls down, the rope holder 8 is protected by the annular member 20, so that the possibility of breakage is low. That is, the support 1c is excellent in safety because the rope holder 8 is not easily broken.

  The annular member 20 is not limited to a circular shape as shown in FIG. That is, as shown in FIG. 7C, a rectangular structure may be used. With such a structure, in addition to having the above-described actions and effects related to the case where the annular member 20 is circular, in the case where it is necessary to install the column 1c close to the building, Since the side can be brought into contact with the building, there is an advantage that the installation state is stabilized.

Moreover, instead of using the fixture 7a, the rope holder 8, and the annular member 20, the rope 9 is formed in a circular shape or a regular polygon shape, and at equal angular intervals around the insertion hole of the column main body 2 provided in the center. It is also possible to use a plate-like member in which a plurality of through holes for insertion are provided in the vicinity of the peripheral edge. In this case, since the structure is simpler than the case of using the fixture 7a, the rope holder 8, and the annular member 20, it can be manufactured at low cost.
In addition, the plate-like member having the above structure with respect to the support column 1c is installed so as to be centered on the support column body 2 and perpendicular to the longitudinal direction instead of the annular member 20, and the rope 9 is formed in the above-described through hole. When inserted, compared to the case where the rope holder 8 and the annular member 20 are used, even when the column main body 2 falls down, the effect that they are hardly damaged is further exhibited. Therefore, the safety is further improved as compared with the case where the rope holder 8 and the annular member 20 are used.

Fig.8 (a) is a front view which shows the external appearance of another form of the support | pillar of this invention, FIG.8 (b) is the top view which expanded the rope holder and annular member in Fig.8 (a). In addition, about the component shown in FIG.1 and FIG.6, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
As shown in FIG. 8A and FIG. 8B, the support column 1d includes a plurality of annular members 20 that differ from the annular member 20 only in diameter in the support column 1c of the second embodiment. It has a structure in which a plurality of annular members 20 and 21 are alternately arranged so as to be centered on the column main body 2 and orthogonal to the longitudinal direction thereof.

The ropes 9 are respectively inserted into through holes 20a and 21a provided in the annular bodies 20 and 21, and an annular member 21 is installed in the vicinity of the lower end 2b of the column main body 2 instead of the connector 7b. .
In the column 1d having such a structure, the range in which the column main body 2 is difficult to bend can be widened without making the rope holder 8 too long. Therefore, workability at the time of carrying and carrying is good.

  The present invention is applicable when it is necessary to install a camera at a high place in order to obtain an image viewed from above.
