Description

[Technical Field]

[0001] The present disclosure relates to a camera mounting member. [Background technology]

[0002] Conventionally, the installation (mounting) of a camera such as a surveillance camera has involved the use of a support part fixed to the mounting location (ceiling, wall, pole, etc.), a hanging bracket connected to the support part for suspending the camera, and a mounting member that is an integrated part configured integrally with the hanging bracket and to which the camera can be attached (see Non-Patent Document 1). Such a mounting member has a tapered pipe thread formed thereon that is fastened to a parallel pipe thread formed on the hanging bracket, and is configured as an integrated part with the hanging bracket by fully tightening the tapered pipe thread onto the parallel pipe thread. The camera is mounted (installed) at the mounting location by attaching the hanging bracket to the support part and then to the mounting member that is an integrated part with the hanging bracket.

[0004] However, because conventional cameras are attached to a hanging bracket and a mounting member that are integrated by tightening the tapered pipe thread and parallel pipe thread, the camera mounting direction, which is determined by the tightening position of the screws, may not be able to be mounted in the camera mounting direction (camera pan rotation direction) desired by the user. Also, camera mounting members have been proposed in which the mounting member and hanging bracket are configured as separate entities, but because the mounting member is provided with a rotation-preventing rib, there is a possibility that the camera cannot be mounted in the camera mounting direction (camera pan rotation direction) desired by the user.

[0005] The present disclosure has been devised in view of the above-described conventional circumstances, and aims to provide a camera mounting member that allows the mounting direction of the camera to be easily adjusted. [Means for solving the problem]

[0006] The present disclosure provides a camera mounting member capable of mounting a camera to a support pipe portion fixed to a support body that supports the camera at a mounting position, the mounting member comprising: a fastening member having a flange portion formed at one end portion opposite to one end portion fixed to the support pipe portion, and a male screw portion having a diameter smaller than that of the flange portion; a camera mounting surface part having a through hole through which the one end portion of the fastening member can be inserted; and a nut that can be threaded onto the male screw portion of the fastening member; the camera mounting surface part that is placed on the flange portion and is rotatable along the rotation direction of the male screw portion is sandwiched between the flange portion and the nut. The flange portion has a female thread portion that penetrates the flange portion in a thickness direction, and the camera mounting surface part is pressed by the tip of a fixing screw that is screwed into the female thread portion from the opposite side to the camera mounting surface part. A camera mounting member is provided. [Effects of the Invention]

[0007] The present disclosure allows the mounting direction of the camera to be easily adjusted. [Brief explanation of the drawings]

[0009] Hereinafter, with reference to the drawings as appropriate, a detailed description of an embodiment specifically disclosing a camera mounting member according to the present disclosure will be provided. However, more detailed description than necessary may be omitted. For example, detailed description of well-known matters or redundant description of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. Note that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter recited in the claims.

[0010] In the following description, the Z axis shown in each drawing indicates the up-down direction.

[0011] 1 is a perspective view of the exterior of a surveillance camera 11 according to the first embodiment. In the first embodiment, the surveillance camera 11 will be described as an example of a camera, but is not limited to this. For example, the camera may be a camera that is installed on any mounting target such as a wall, ceiling, pillar, beam, or pole.

[0012] 1 may be a monocular camera or a compound-eye camera. The external shape of the surveillance camera 11 and the arrangement of the camera unit 13 (imaging section) shown in FIG. 1 are merely examples and are not limiting. For example, the surveillance camera 11 may be a twin-eye camera in which two camera units (imaging sections) are arranged side by side in a predetermined direction.

[0013] The camera unit 13 referred to here is an imaging unit for capturing images of the imaging area, and may be equipped with a solid-state imaging element such as a CCD (Charged-Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor), and may also be equipped with a zoom function, a tilt rotation function, etc.

[0014] Surveillance camera 11 according to the first embodiment captures an image of an imaging area to be monitored by camera unit 13 covered by dome-shaped dome cover 15. Support section 17 (an example of a support) is fixed to a wall on which surveillance camera 11 is to be mounted. Surveillance camera 11 is attached to a predetermined mounting position by being connected via mounting member 27 to support pipe section 19B of hanging bracket 19A connected to support section 17.

[0015] FIG. 2 is a top perspective view of the mounting member 27. FIG.

[0016] The mounting member 27 includes a fixing screw 29 (see FIG. 1), a fastening member 21, a camera mounting surface part 23, a nut 25, and a fixing screw 31 (see FIG. 3).

[0017] Fastening member 21 is formed in a tubular shape, and one end (upper end) is inserted into the inside of cylindrical support pipe portion 19B that hangs down from hanging bracket 19A. A plurality of (for example, four) holes (not shown), through which fixing screws 29 are inserted, are drilled at approximately equal intervals in the circumferential direction on the outer periphery of support pipe portion 19B.

[0018] On the other hand, the fastening member 21 has a cylindrically formed connecting tube portion 39. The connecting tube portion 39 has a plurality of fixing screw holes 33 (see FIG. 2) into which fixing screws 29 (see FIG. 1) are threaded, and the fixing screw holes 33 are provided at approximately equal intervals in the circumferential direction at positions corresponding to the plurality of holes provided in the support pipe portion 19B.

[0019] The fastening member 21 inserted inside the support pipe portion 19B is fixed to the support pipe portion 19B by fastening a fixing screw 29 penetrating from the outer periphery of the support pipe portion 19B into a fixing screw hole 33.

[0020] FIG. 3 is a bottom perspective view of the mounting member 27. FIG.

[0021] The fastening member 21 has a flange portion 35 and a male thread portion 37, which has a diameter smaller than that of the flange portion 35, formed in this order from the other end (lower end) to the upper end. A connecting tubular portion 39 is provided adjacent to the upper end side of the male thread portion 37.

[0022] As an example, the camera mounting surface part 23 in the first embodiment is formed in a substantially circular plate shape. The camera mounting surface part 23 may be formed in a shape corresponding to the surveillance camera 11 to be mounted, such as an elliptical plate shape or an oblong plate shape.

[0023] The surveillance camera 11 is attached via an attachment fitting (not shown) to the attachment surface 41 of the camera attachment surface component 23. A fixing post 43 for fixing the attachment fitting protrudes from the attachment surface 41, and an attachment fixing screw 45 (see FIG. 4) is screwed into the attachment fitting with the attachment fitting passing through.

[0024] A substantially circular through-hole 47 is formed in the center of the camera mounting surface part 23, substantially concentric with the fastening member 21. The upper end of the fastening member 21 (i.e., the connecting tube part 39) is inserted into the through-hole 47 from the mounting surface 41 side of the camera mounting surface part 23, on which the surveillance camera 11 is mounted. By inserting the fastening member 21 into the through-hole 47 from the mounting surface 41 side of the camera mounting surface part 23, the peripheral part of the through-hole 47 rests on the flange part 35 of the fastening member 21.

[0025] When the peripheral portion of the through hole 47 of the camera mounting surface part 23 is placed on the flange portion 35 of the fastening member 21, the connecting tube portion 39 and the male thread portion 37 protrude from the surface (top surface) opposite the mounting surface 41 (see Figure 2).

[0026] The male thread portion 37 protruding from the through hole 47 is screwed into the nut 25. The camera mounting surface part 23 is fastened to the fastening member 21 in a state where the peripheral portion of the through hole 47 of the camera mounting surface part 23 is sandwiched between the flange part 35 and the contact surface 49 (lower surface) of the nut 25 while placed on the flange part 35. In other words, the peripheral portion of the through hole 47 is sandwiched between the contact surface 49 of the nut 25 and the pressed surface 51 (see FIG. 5 ), which is the mounting surface of the flange part 35. In this way, the fastening member 21 and the camera mounting surface part 23 are fixed together.

[0027] 2, the camera mounting surface part 23 has a mark Mk (an example of a mark) that determines the front position (imaging direction) of the surveillance camera 11. By providing the mark Mk on the inside of the camera mounting surface part 23 (i.e., on the mounting surface 41 side), when fixing the camera mounting surface part 23 using a fixing screw 31 (described later), the position of the camera mounting surface part 23 to be fixed can be confirmed while screwing the fixing screw 31.

[0028] Before the nut 25 is tightened, that is, with the peripheral edge of the through-hole 47 of the camera mounting surface part 23 sandwiched between the flange part 35 and the contact surface 49 (lower surface) of the nut 25, the surveillance camera 11 is clamped so that the camera mounting surface part 23 can rotate freely in the Pan direction relative to the mounting member 27. Note that the Pan direction here refers to the direction of rotation about the Z axis.

[0029] The surveillance camera 11 can be adjusted to the desired installation direction by rotating the camera mounting surface part 23 in the Pan direction by the worker performing the installation work. After the camera mounting surface part 23 has been adjusted to the desired installation direction by the user, the surveillance camera 11 is clamped and fixed so that it cannot rotate in the Pan direction by tightening the nut 25.

[0030] For example, when the surveillance camera 11 captures images in both directions along the center line 59 of the hanging bracket 19A shown in Figure 1 using the camera unit 13, the imaging direction (mounting direction) of the camera unit 13 attached to the camera mounting surface part 23 can be adjusted to the imaging direction A by adjusting the mark Mk on the mounting surface 41 of the camera mounting surface part 23 to align with the imaging direction A and then tightening the nut 25.

[0031] Fig. 4 is an enlarged perspective view of a main part of the flange portion 35. The fastening member 21 shown in Fig. 4 is shown in a state where the camera mounting surface part 23 is sandwiched between the nut 25 and the flange portion 35 and fixed to the support pipe portion 19B.

[0032] A female thread portion 61 (see FIG. 7) that penetrates in the Z direction is formed in the flange portion 35. The camera mounting surface component 23 is sandwiched between the nut 25 and the flange portion 35, and the tip of the fixing screw 31 that is screwed into the female thread portion 61 of the flange portion 35 from the side opposite to the camera mounting surface component 23 abuts against the female thread portion 61. A plurality of (for example, two) female thread portions 61 are provided at approximately equal intervals along the circumferential direction of the flange portion 35.

[0033] The length under the head of the fixing screw 31 is longer than the thickness of the flange portion 35. As a result, when the fixing screw 31 is tightened while being threaded into the female thread portion 61, the flange portion 35 abuts against the periphery of the through hole 47 of the camera mounting surface component 23.

[0034] When the fixing screw 31 is further tightened with the flange portion 35 abutting the periphery of the through-hole 47 of the camera mounting surface component 23, the camera mounting surface component 23 is lifted in the Z direction and is fixed by being sandwiched between the contact surface 49 of the nut 25 and the fixing screw 31. The camera mounting surface component 23 sandwiched between the contact surface 49 of the nut 25 and the fixing screw 31 cannot rotate in the Pan direction.

[0035] FIG. 5 is a cross-sectional view of the mounting member 27 shown in FIG. 4 taken along CC line.

[0036] When the camera mounting surface component 23 is fixed (clamped) in the fastening member 21, the inner space of the connecting tube portion 39 opens to the inside of the mounting surface 41 of the camera mounting surface component 23. In other words, the inner space of the fastening member 21 communicates with the internal spaces of the support portion 17, the hanging bracket 19A, and the support pipe portion 19B, and functions as a duct 63 for drawing the power line, communication cable, etc. of the surveillance camera 11 into the mounting surface 41.

[0037] 3 is inserted into the duct 63 of the fastening member 21. The fall prevention wire 65 is passed through the inside of the support pipe portion 19B and pulled into the duct 63, and then pulled out from the mounting surface side of the camera mounting surface component 23 (i.e., the opening of the flange portion 35) and placed on the mounting surface 41. The fall prevention wire 65 placed on the mounting surface 41 is hooked onto a thin small piece portion 67 formed on the flange portion 35, as shown in FIG.

[0038] FIG. 6 is a cross-sectional view taken along line DD in FIG.

[0039] The flange portion 35 has a plurality of (for example, two) thin piece portions 67 formed at approximately equal intervals in the circumferential direction of the flange portion 35. The thin piece portions 67 are formed so that portions of the flange portion 35 are thin, for example, by reducing the thickness of the surface facing the camera mounting surface component 23. As a result, a gap 69 (see FIG. 7) is formed between the thin piece portions 67 and the camera mounting surface component 23.

[0040] FIG. 7 is an enlarged view of the main part of FIG.

[0041] In the fastening member 21, the fixing screw 31 that pushes the camera mounting surface part 23 toward the nut 25 is screwed into the female thread portion 61 of the thin piece portion 67 that is formed by thinning a portion of the flange portion 35.

[0042] When the fixing screw 31 is screwed into the camera mounting surface part 23 and pushes it up, it receives a reaction force from the camera mounting surface part 23. At this time, the thin piece part 67 is formed to be thinner than the thick flange part 35, and therefore is elastically deformed by the reaction force received from the camera mounting surface part 23. The thin piece part 67 makes it possible to make the nut 25 less likely to loosen due to its elastic restoring force.

[0043] The thin piece portion 67 is thinned by grinding the surface facing the camera mounting surface part 23. As a result, a gap 69 is formed between the thin piece portion 67 and the camera mounting surface part 23. A circular loop portion 71 (see FIG. 3) provided at the tip of the fall prevention wire 65 can be hooked into the gap 69, and the tip of the fixing screw 31 threaded into the thin piece portion 67 abuts against the camera mounting surface part 23, thereby closing the radially outer open side of the flange portion 35.

[0044] As a result, the gap 69 is closed and the loop portion 71 of the fall prevention wire 65 hooked on the thin piece portion 67 does not come off the thin piece portion 67, and is firmly held in the flange portion 35. In other words, the thin piece portion 67 has both the function of preventing the nut 25 from loosening and the function of fixing the fall prevention wire 65.

[0045] As described above, the camera mounting member 27 of embodiment 1 is a camera mounting member 27 that can mount a surveillance camera 11 to a support pipe portion 19B that is fixed to a support portion 17 (an example of a support body) that supports the surveillance camera 11 (an example of a camera) at an mounting position, and is equipped with a flange portion 35 formed at the other end opposite the one end fixed to the support pipe portion 19B, a fastening member 21 that has a male thread portion 37 with a smaller diameter than the flange portion 35, a camera mounting surface part 23 that has a through hole through which one end of the fastening member 21 can be inserted, and a nut 25 that can be screwed onto the male thread portion 37 of the fastening member 21, and the camera mounting surface part 23 that is placed on the flange portion 35 and can rotate along the rotational direction of the male thread portion 37 is clamped between the flange portion 35 and the nut 25.

[0046] As a result, by inserting the fastening member 21 through the through hole 47, the camera mounting member 27 according to embodiment 1 can support the camera unit 13 in a state in which the periphery of the through hole 47, which is formed with a smaller diameter than the flange portion 35, is placed on the flange portion 35 of the fastening member 21, and in a state in which the mounting direction of the camera unit 13 is rotatable in the Pan rotation direction. With the fastening member 21 inserted through the through hole 47, the camera mounting member 27 tightens the periphery of the through hole 47 on the upper surface (the surface opposite the mounting surface 41) of the camera mounting surface component 23 by screwing the nut 25 onto the male threaded portion 37 protruding from the through hole 47 of the camera mounting surface component 23 and tightening it. As a result, the fastening member 21 rotates the camera mounting surface part 23 placed on the flange part 35 to the desired mounting position by the user before completing the tightening of the nut 25, and then the worker tightens the nut 25, thereby clamping the camera mounting surface part 23 between the nut 25 and the flange part 35 and locking the camera mounting surface part 23 so that it cannot rotate in the pan direction. Therefore, the camera mounting member 27 can more easily adjust the mounting direction of the camera unit 13 attached to the camera mounting surface part 23.

[0047] Furthermore, the flange portion 35 of the camera mounting member 27 according to the first embodiment has a female thread portion 61 that penetrates the flange portion 35 in the thickness direction, and the camera mounting surface part 23 is pressed by the tip of the fixing screw 31 that is screwed into the female thread portion 61 from the opposite side of the camera mounting surface part 23. As a result, the camera mounting member 27 according to the first embodiment can be fixed in a state in which the tip of the fixing screw 31 pushes up the camera mounting surface part 23 in the Z direction by screwing the fixing screw 31 into the female thread portion 61 from the opposite side of the camera mounting surface part 23 and tightening it. In other words, by tightening the fixing screw 31, the camera mounting member 27 can bring the camera mounting surface part 23 into stronger pressure contact with the nut 25, enabling more secure fixation.

[0048] Furthermore, in the camera mounting member 27 according to the first embodiment, the length under the head of the fixing screw 31 is longer than the thickness of the flange portion 35. As a result, in the camera mounting member 27 according to the first embodiment, the fixing screw 31 fastened to the female thread portion 61 penetrates the flange portion 35, and the tip of the penetrating fixing screw 31 abuts against the camera mounting surface part 23, thereby pressing the camera mounting surface part 23 in the direction of the nut 25 (Z direction). Note that the overall length of the fixing screw 31 may be any length that does not interfere with the camera unit 13 attached to the mounting surface 41 of the camera mounting surface part 23 when the camera mounting surface part 23 has been pressed.

[0049] Furthermore, the camera mounting surface part 23 of the camera mounting member 27 according to the first embodiment has a mark Mk (an example of a mark) that indicates the front position of the camera. As a result, the camera mounting member 27 according to the first embodiment makes it possible to adjust the fixed position of the camera mounting surface part 23, that is, the mounting direction of the camera unit 13 mounted on the camera mounting surface part 23, while visually checking the mark Mk on the camera mounting surface part 23.

[0050] Furthermore, the female thread portion 61 of the mounting member 27 of the camera according to the first embodiment is provided on a thin piece portion 67 formed by thinning a portion of the flange portion 35. As a result, in the mounting member 27 of the camera according to the first embodiment, the thin piece portion 67 is elastically deformed by the reaction force received from the camera mounting surface part 23 when the fixing screw 31 is screwed in, and the elastic restoring force of the thin piece portion 67 against this reaction force makes it difficult for the nut 25 to loosen.

[0051] Furthermore, thin piece portion 67 of mounting member 27 of the camera according to embodiment 1 is inserted through the inside of fastening member 21 and support pipe portion 19B and locks fall prevention wire 65 drawn out from the other end. As a result, even if the fixation between support pipe portion 19B and fastening member 21 loosens and mounting member 27 comes off support pipe portion 19B, fall prevention wire 65, one end of which is fixed to support portion 17, gets caught on thin piece portion 67 of flange portion 35 of fastening member 21, preventing surveillance camera 11 (camera unit 13) from falling.

[0052] Although various embodiments have been described above with reference to the drawings, it goes without saying that the present disclosure is not limited to such examples. It is clear that a person skilled in the art can conceive of various modifications, alterations, substitutions, additions, deletions, and equivalents within the scope of the claims, and it is understood that these also naturally fall within the technical scope of the present disclosure. Furthermore, the components of the various embodiments described above may be combined in any manner without departing from the spirit of the invention.

[0053] This application is based on a Japanese patent application (Patent Application No. 2022-169944) filed on October 24, 2022, the contents of which are incorporated herein by reference. [Industrial Applicability]
