Description

The present invention relates to a camera device mounting box for mounting camera devices such as security cameras and surveillance cameras, and a method for installing camera devices.

A mounting box or mounting device is used to attach the camera equipment to a structure such as a building wall or a pole. One such mounting box or mounting device is described in Patent Document 1. The camera mounting device in Patent Document 1 is box-shaped and includes a first mounting base member for mounting the camera at the camera installation location, and a lid-shaped second mounting base member attached to the first mounting base member by a hinge so that it can be opened and closed. The first mounting base member and the second mounting base member form an internal wiring chamber through which the camera wiring is passed. The camera is installed on the outer surface of the second mounting base member.

This camera mounting device allows the user to open the second mounting base member and connect the cable on the camera side of the internal wiring chamber to the cable on the installation surface side. Because this camera mounting device has an internal wiring chamber, the camera wiring is not exposed to the outside, improving the external appearance.

When installing a camera, typically a confirmation cable is connected to a handheld monitor used for checking the installation, and the camera's orientation is adjusted while checking the image on the handheld monitor from near the camera. After adjustments are made, the confirmation cable is removed from the handheld monitor, and the camera's image can be remotely checked and monitored through a video cable connected to a surveillance monitor in a guard room, etc.

JP 2005-323037 A

However, when the camera mounting device of Patent Document 1 is used to connect the camera cable to a handheld small monitor and adjust the camera's orientation while checking the small monitor at hand, in the normal state where the lid-like second mounting member on which the camera is installed is closed, the second mounting member covers the internal wiring chamber, so it is naturally impossible to connect the camera's confirmation cable to the small monitor. If the second mounting member is slightly open relative to the first mounting member, it is possible to connect the camera's confirmation cable to the small monitor, but it is difficult and tricky to pull out the cable through the narrow, slightly open gap to adjust the camera's orientation, etc.

If a confirmation cable is pulled out from a separate pull-out hole and connected to a small monitor, it is possible to adjust the camera's orientation when the second mounting member on which the camera is installed is in the normal state when closed. However, after adjustment, it is necessary to reconnect the cable from the small monitor to the cable on the installation surface side, and in doing so, the second mounting member must be opened again, which means the camera's position moves from the normal state, and the camera's orientation, which was once fine-tuned, may become distorted. Furthermore, these procedures are tedious.

The present invention aims to provide a camera equipment mounting box and a camera equipment installation method that allows camera equipment to be installed in a good-looking manner by storing and covering the connection parts and excess cable length, and allows camera equipment to be installed easily and efficiently in the correct position.

First Embodiment
First, a camera equipment mounting box and a method for installing camera equipment according to a first embodiment of the present invention will be described with reference to the drawings.
The camera equipment mounting box is box-shaped, has a cable accommodating space formed therein, has a camera mounting box body and an opening/closing body, and is used to mount camera equipment such as security cameras and surveillance cameras. Each component will be described in detail below. In the following description, the up-down direction in Fig. 1 is taken to be the up-down direction of each component.

1 to 4, the camera mounting box main body 10A includes a fixing part 11 that is fixed to a structure, a camera mounting part 12 to which the camera device 60 is attached, and an assembly part 13 to which the opening/closing body 40A is attached. More specifically, the camera mounting box main body 10A is formed into a rectangular box shape as a whole, and is composed of a bottom wall 14 that faces a wall surface 80 of a building, which is a structure, and a peripheral wall 15 that stands upright from the bottom wall 14. The part surrounded by the tip side of the peripheral wall 15 forms an opening 16. The bottom wall 14 is a fixing surface 17 that faces the structure when it is fixed to the structure by the fixing part 11. The assembly part 13 is formed by two opening/closing shafts 18 at the top and bottom provided at the tip of the opening 16 side of the peripheral wall 15 on one of the left and right sides.

The bottom wall 14 has fixing flanges 19 protruding laterally at the four corners of its outer surface for fixing to the wall surface 80 of the building, and the fixing flanges 19 have insertion holes 20 through which fixing screws are inserted. In addition, a recess 21 recessed into an inverted trapezoid shape is formed in the center of each of the upper and lower ends of the bottom wall 14, and a belt insertion frame 22 is installed in the middle of the recess 21 on approximately the same plane as the bottom wall 14 surface. In other words, the belt insertion frame 22 is provided above and spaced apart from the bottom surface of the inverted trapezoid recess 21, and a belt (not shown) can be inserted between the bottom surface of the recess 21 and the belt insertion frame 22. The recess 21 and the belt insertion frame 22 constitute a separate fixing part 11, and the camera equipment mounting box 1A can be fixed to a pole, which is a separate structure, using a belt.

Furthermore, lower holes 24 are provided at the upper and lower ends of the bottom wall 14 for attaching a fixing member 23, which will be described later, and the lower holes 24 are blocked with knockouts. The fixing member 23 and the lower holes 24 form yet another fixing part 11. A pull-out hole 25 for pulling out the power cable 70 and the video cable 71 is provided in the center of the bottom wall 14, and is also blocked with knockouts.

The peripheral walls 15 stand perpendicularly from the peripheral end of the bottom wall 14, and of the four peripheral walls 15, the lower peripheral wall 15 shown in FIG. 1 is a surface that extends in a direction away from the structure, and serves as a camera mounting surface 26 having a camera mounting section 12 to which a camera device 60 is attached. The camera mounting section 12 consists of a camera side cable passage hole 27 through which camera side cables consisting of a power cable 72 and a video cable 73 connected to the camera device 60 pass, and screw holes 28 formed around it. A bushing 29 is attached to the camera side cable passage hole 27 to cover the opening.

The bushing 29 is made of rubber, soft resin, etc., and is flexible. As shown in FIG. 5, the bushing 29 is generally disk-shaped, and a groove 29b with a U-shaped cross section is formed around the entire circumference in the middle of the thickness direction of the outer periphery, and the groove 29b is formed to a width slightly smaller than the plate thickness of the peripheral wall 15. The bushing 29 has a ring portion 29a formed on one side sandwiching the groove 29b, and a disk portion 29c formed on the other side. By pushing the ring portion 29a into the camera side cable passage hole 27, the peripheral end of the camera side cable passage hole 27 fits into the groove 29b, and the ring portion 29a and the disk portion 29c are attached to the camera side cable passage hole 27 by sandwiching the peripheral end of the camera side cable passage hole 27.

The inside of the disk portion 29c of the bushing 29 is blocked by six fan-shaped blocking pieces 29d, and each blocking piece 29d is connected to each other by a thin-walled portion 29e formed with a groove having a triangular cross section, which can be cut and split. When inserting a cable, the tip of the cable breaks through the center of the disk portion 29c and cuts and splits the thin-walled portion 29e between the blocking pieces 29d to allow the cable to pass through. This prevents rainwater and debris from entering the camera equipment mounting box 1A before the cable breaks through, and even after the cable is inserted, the tip of each blocking piece 29d is in close contact with the outer surface of the cable to prevent rainwater and the like from entering. The screw pilot holes 28 are mounting holes for mounting the camera equipment 60, and since the screw mounting position differs depending on the type of camera equipment 60, multiple holes are formed to accommodate this.

Furthermore, on both sides of the camera mounting part 12 of the lower peripheral wall 15, cable inlets 30 are provided that can introduce the power cable 70 wired along the wall surface 80 of the building into the camera mounting box main body 10A. A lock nut 31 shown in FIG. 6 is provided inside the lower peripheral wall 15 at the cable inlet 30, and a cap 32 shown in FIG. 6 is screwed onto the lock nut 31 from the outside. The cap 32 has a screwing part 32a with a male thread formed on the outer circumferential surface of a cylinder, and a blocking part 32b formed in a disk shape that blocks one opening of the cylinder and has a large number of small projections and recesses formed on the outer circumferential edge for gripping. The cap 32 is inserted into the cable inlet 30 from the outside and screwed onto the lock nut 31 to clamp the peripheral wall 15. Although not shown, a packing is interposed between the cap 32 and the lock nut 31 as necessary. The camera mounting part 12 and the cable inlet 30 are provided on the lower peripheral wall 15, so that rainwater is less likely to enter.

In addition, drainage holes 33 are provided in two places on the left and right ends of the lower peripheral wall 15, and the drainage holes 33 are blocked with knockouts. By punching out these holes, water can be naturally drained when it gets into the camera mounting box main body 10A. However, the rectangular ring-shaped packing 41 provided on the opening/closing body 40A (described later) prevents water from entering the camera mounting box main body 10A, and drainage is usually not necessary, so the drainage holes 33 do not have to be provided.

As shown in FIG. 3, the other of the left and right peripheral walls 15 has two upper and lower closure flanges 34 at the end of the opening 16 side that protrude horizontally outward along the opening surface of the camera mounting box main body 10A. The closure flanges 34 are formed into nuts into which the closure screws 42a of the opening/closing body 40A are screwed.

Next, the opening/closing body 40A is formed in a generally flat plate shape, is supported by the opening/closing shaft 18 on the camera mounting box main body 10A, and is assembled so as to be movable between an open position and a closed position. When the opening/closing body 40A moves to the closed position relative to the camera mounting box main body 10A, it closes the opening 16 to form a cable housing space 50 inside the camera mounting box main body 10A. The cable housing space 50 contains the excess length of the cable, the cable connection part, etc. On the other hand, when the opening/closing body 40A moves to the open position relative to the camera mounting box main body 10A, it opens the opening 16 to expose the cable housing space 50 to the outside. The opening/closing body 40A opens and closes in a range of approximately 180 degrees relative to the camera mounting box main body 10A around the opening/closing shaft 18, and the size of the cable housing space 50 exposed to the outside by the movement of the opening/closing body 40A is at least large enough for the fingers holding the cable to enter. Around the inside of the opening/closing body 40A, a rectangular ring-shaped packing 41 is provided all around the periphery, closely fitting the tip of the opening 16 side of the peripheral wall 15 on each of the four sides of the camera mounting box main body 10A. By providing the packing 41 on the opening/closing body 40A, when the opening/closing body 40A is closed, communication between the cable housing space 50 and the outside is blocked in a watertight state.

A blocking flange 42 is provided on the end of the opening/closing body 40A opposite the opening/closing shaft 18, which is one of the left and right sides of the opening/closing body 40A, protruding horizontally outward along the opening surface of the camera mounting box main body 10A, and a screw 42a is screwed into the nut of the blocking flange 34 of the camera mounting box main body 10A. An L-shaped metal fitting 43 shown in Figures 1 and 8(h) is interposed between the blocking flange 42 on the lower side of the opening/closing body 40A and the screw 42a, and a wire hole 43a through which a wire (not shown) is inserted is provided in one bent piece of the L-shaped metal fitting 43. By inserting a wire into the wire hole 43a and wrapping it around any part of the camera equipment 60, it is possible to prevent the camera equipment 60 from falling off in the unlikely event of an accident. The opening/closing body 40A is maintained in a closed state by tightening the screw 42a against the nut of the blocking flange 34. When opening the opening/closing body 40A, the screw 42a is screwed back until it comes off the nut of the closing flange 34 of the camera mounting box main body 10A. If a screw retaining washer 42b is fitted onto the outer surface of the screw 42a as shown in FIG. 4, the screw retaining washer 42b will press against the outer surface of the screw to prevent the screw from falling out when it is screwed back.

Next, a method for installing the camera device 60 using the camera device mounting box 1A configured as described above will be described with reference to Figures 7 and 8. Note that in Figures 7 and 8, a case will be described in which the structure is the wall surface 80 of a building.

First, in the process of fixing the camera mounting box body to the structure, as shown in FIG. 7(a), the fixing screws are inserted into the insertion holes 20 of the fixing flanges 19 at the four corners of the bottom wall 14 and screwed to the wall surface 80 of the building, and the camera equipment mounting box 1A is installed and fixed to the wall surface 80. Then, although not shown, the knockout of the pull-out hole 25 in the center of the bottom wall 14 is broken, and the ends of the power cable 70 and the video cable 71, which are the structure side cables pulled out from the wall surface 80, are pulled out from the pull-out hole 25 into the cable housing space 50. At this time, the opening and closing body 40A may be in an open state. Note that both or either of the ends of the power cable 70 and the video cable 71 may be pulled out into the cable housing space 50 from the cable inlet 30 of the lower peripheral wall 15.

Next, in the process of mounting the camera equipment, the tip of the camera side cable is inserted through the center of the disk portion 29c of the bushing 29 of the camera side cable passage hole 27 of the camera mounting part 12, and the tip of the camera side cable is pulled out into the cable housing space 50. As shown in FIG. 7(b), the mounting flange 61 of the camera equipment 60 is placed against the lower peripheral wall 15 of the camera mounting box main body 10A, and the screw is inserted into the screw hole 28 to mount the camera equipment 60 to the lower peripheral wall 15. Here, the camera side cables include a power cable 72 and a video cable 73 connected to the camera equipment 60, as well as a confirmation cable 74, and the power cable 72 and the video cable 73 are respectively connected to the power cable 70 and the video cable 71 of the structure side cable.

Next, as shown in FIG. 7(c), with the opening/closing body 40A open and the cable housing space 50 facing the outside, the power cable 70 that was pulled out into the cable housing space 50 from the pull-out hole 25 in the bottom wall 14 or the cable inlet 30 in the lower peripheral wall 15 beforehand or during wiring here is connected to the power cable 72 of the camera side cable that was pulled out into the cable housing space 50 from the camera side cable passage hole 27 in the lower peripheral wall 15.

Next, in the process of pulling out the tip of the confirmation cable of the camera device to the outside, as shown in FIG. 7(d), the tip of the confirmation cable 74 connected to the camera device 60 is pulled out to the outside from the opening 16 of the camera mounting box main body 10A. These processes from FIG. 7(a) to (d) are the temporary installation process before the camera device 60 is installed in the correct position.

Once the camera device 60 has been temporarily installed in the camera mounting box main body 10A in this manner, as shown in FIG. 8(e), the tip of the confirmation cable 74 pulled out to the outside is connected to the tip of the monitor side cable 75 connected to a confirmation monitor (not shown). Then, while watching the image on the confirmation monitor, the installation state of the camera device 60, such as its orientation, is set and adjusted. The confirmation monitor can be any type of small monitor, or a tablet can also be used.

After setting and adjusting the orientation of the camera device 60, the camera device 60 is not moved in order to prevent the orientation of the camera device 60 from fluctuating in subsequent operations. Instead, the confirmation cable 74 is separated from the monitor-side cable 75 of the confirmation monitor and returned to the cable housing space 50 through the opening 16 as shown in FIG. 8(f). Then, as shown in FIG. 8(g), the video cable 73 of the camera-side cable and the video cable 71 of the structure-side cable are connected. The tip of the confirmation cable 74 housed in the cable housing space 50 is pulled out and connected to the monitor-side cable 75 when adjusting the orientation of the camera device 60 as necessary. However, after adjusting the camera device 60, the confirmation cable 74 may be disconnected from the camera device 60. Note that the video cable 71 and the video cable 73 may be connected before this.

8(h), the opening/closing body 40A is rotated to the closed position about the opening/closing shaft 18. This blocks communication between the cable housing space 50 and the outside in a watertight manner.
It should be noted that the details of the above operations may be slightly different from those described above.

The above describes the case where the structure is the wall surface 80 of a building, but if the structure is a pole made of a circular tube, in the first process of fixing the camera equipment mounting box to the structure shown in Figure 7(a), the camera equipment mounting box 1A can be fixed using the fixing part 11 consisting of the recess 21 and belt insertion frame 22 provided at the upper and lower ends of the bottom wall 14. In other words, although not shown, the camera equipment mounting box 1A can be fixed by inserting a belt (not shown) into the gap between the recess 21 and the belt insertion frame 22 and wrapping it around the pole.

In addition, when the structure is a pipe made of a circular tube, it can be fixed using another fixing part 11, a fixing member 23 with a central part formed into an arc surface as shown in FIG. 9. That is, as shown in FIG. 9, screws are inserted into long holes formed in the flat mounting plate parts on both sides of the arc surface of the fixing member 23, and these are screwed into pilot holes 24 provided in the upper and lower parts of the bottom wall 14 to attach the fixing member 23 to the bottom wall 14. After that, a belt is inserted into the belt insertion holes 23a made of long holes formed on both sides of the arc surface of the fixing member 23, and it can be wrapped around the pipe and fixed directly. The camera equipment mounting box 1A can also be fixed indirectly to the pipe using a separate member.

Next, the operation of the camera equipment mounting box 1A and the method of installing the camera equipment 60 according to this embodiment will be described.
In the camera equipment mounting box 1A of this embodiment, the camera equipment 60 is attached to the camera mounting box main body 10A, and the opening/closing body 40A is provided at a location unrelated to the fixing of the camera equipment 60 and its fixing to a structure, and the cable accommodating space 50 is exposed to the outside by opening and closing the opening/closing body 40A relative to the camera mounting box main body 10A fixed to a structure with the camera equipment 60 attached. For this reason, in the past, the camera equipment 60 was fixed to the opening/closing body, and after adjusting the orientation, etc. of the camera equipment 60, when the opening/closing body was opened again to disconnect the monitor cable and reconnect it to the video cable, the camera equipment 60 moved along with the opening/closing body. As a result, when the cable was reconnected and the opening/closing body was closed again, the orientation, etc. of the camera equipment 60 could be shifted, and this work was also troublesome. However, with the camera equipment mounting box 1A of this embodiment, it is possible to perform the work of connecting the camera equipment 60 to the video cable 71 and the work of checking the connection state by opening only the opening/closing body 40A to which the camera equipment 60 is not attached, without moving the camera equipment 60 at all, so that the orientation, etc. of the camera equipment 60 will not be shifted by these operations, and therefore the camera equipment 60 can be easily installed in the correct position with good workability.

In addition, the cable connection parts and excess cable length are stored in the cable storage space 50 and are covered and hidden by the camera equipment mounting box 1A, so the camera equipment 60 can be installed with a good appearance.

Second Embodiment
Next, a camera equipment mounting box and a method of installing camera equipment according to a second embodiment of the present invention will be described with reference to the drawings.
In the camera equipment mounting box 1A of the first embodiment, the camera mounting box main body 10A is formed in a box shape, and the opening/closing body 40A is formed in a substantially flat plate shape, pivoted on an opening/closing shaft 18, and assembled to the camera mounting box main body 10A so as to be freely opened and closed by rotation, whereas in the camera equipment mounting box 1B of the second embodiment, as shown in Fig. 10, the camera mounting box main body 10B is formed in a substantially L-shaped plate shape, the opening/closing body 40B has a peripheral wall 15 formed in a U-shaped plate shape, and the opening/closing body 40B is assembled by sliding it vertically relative to the camera mounting box main body 10B, which is different from the camera equipment mounting box 1A of the first embodiment. Hereinafter, the camera equipment mounting box 1B of the second embodiment will be specifically described, focusing on the differences.

The camera equipment mounting box 1B of the second embodiment is formed in a box shape, similar to the camera equipment mounting box 1A of the first embodiment, and includes a camera mounting box main body 10B and an opening/closing body 40B. However, while the camera equipment mounting box 1A of the first embodiment is formed in a box shape by itself being the camera mounting box main body 10A, the camera equipment mounting box 1B of the second embodiment is formed in a box shape by assembling the camera mounting box main body 10B and the opening/closing body 40B.

The camera mounting box body 10B of the second embodiment is formed of a rectangular bottom wall 14, a lower peripheral wall 15 erected perpendicularly from the side end of one side of the bottom wall 14, and flanges 35 erected slightly perpendicularly from the side ends of three sides of the bottom wall 14, that is, the fixing surface 17 that abuts against the structure and the camera mounting surface 26, and the whole is formed in a roughly L-shaped plate shape. The bottom wall 14 and the lower peripheral wall 15 are formed in the same manner as in the first embodiment. The outer surface of the pair of flanges 35, 35 erected from the left and right side ends of the bottom wall 14 is provided with a slide groove 36 consisting of a concave groove that extends all the way up and down.

On the other hand, the opening/closing body 40B is formed of a pair of left and right side walls 44, 44 formed in a U-shaped plate shape, a top wall 45, and a rectangular plate-shaped front wall 46. Each side end of the pair of left and right side walls 44, 44 is provided with an engagement protrusion 47 that protrudes into the interior of the cable housing space 50 over the entire vertical direction and engages with the slide groove 36 of the bottom wall 14 of the camera mounting box main body 10B.

The opening/closing body 40B exposes or closes the cable accommodation space 50 by engaging the engagement protrusions 47 on the left and right side walls 44 with the slide grooves 36 of the flanges 35 of the camera mounting box main body 10B and sliding up and down. Because the camera equipment mounting box 1B of the second embodiment is formed in this way, it does not have the opening/closing shaft 18, the closing flange 34, and the nut provided on the camera mounting box main body 10A of the first embodiment, nor the closing flange 42 and the screw 42a provided on the opening/closing body 40B.

The camera equipment mounting box 1B of the second embodiment can install the camera equipment 60 on a structure in the same manner as the camera equipment mounting box 1A of the first embodiment, and operates in the same manner. However, as described above, the opening/closing body 40B slides up and down to expose the cable housing space 50 to the outside. FIG. 11(a) shows the state in which the camera equipment mounting box 1B is fixed to the wall surface 80 of a building, which is a structure, in the procedure for installing the camera equipment 60. FIG. 11(b) shows the state in which the camera equipment 60 is attached to the peripheral wall 15 located on the lower side of the camera mounting box main body 10B, and the opening/closing body 40B is opened to expose the cable housing space 50 to the outside in order to pull the camera side cable into the inside of the camera mounting box main body 10B.

In the procedure for installing the camera device 60 in the first embodiment, when the camera device 60 is temporarily installed in the camera mounting box main body 10A and the mounting state such as the orientation of the camera device 60 is set and adjusted, the confirmation cable 74 is pulled out to the outside from the opening 16 on the front side of the camera mounting box main body 10A by opening the opening/closing body 40A as shown in FIG. 8(e), and the confirmation cable 74 and the monitor side cable 75 are connected, but this is not limited to this, and the confirmation cable 74 may be pulled out to the outside from the opening by removing the cap 32 of the cable inlet 30 provided on the lower peripheral wall 15 of the camera mounting box main body 10A. This is the same for the second embodiment. In this case, after the connection, the confirmation cable 74 is pushed back into the cable housing space 50 from the cable inlet 30, and the cap 32 is attached to the cable inlet 30 again to block the communication between the cable housing space 50 and the outside in a watertight state. In this embodiment, the camera mounting section 12 and the outlet for the monitor confirmation cable 74 are located on the same surface of the lower peripheral wall 15.

In other words, as long as the task of installing the camera device 60 in the correct position can be performed easily and efficiently, the camera mounting section 12 and the opening for pulling out the confirmation cable 74 may be formed on different surfaces of the camera device mounting boxes 1A and 1B, or may be formed on the same surface.

The camera equipment mounting box of the present invention is not limited to the camera equipment mounting boxes 1A and 1B of the above embodiments, so long as the opening and closing body can be opened and closed to connect the camera side cable or check the connection state without moving the camera equipment 60 after adjusting the orientation of the camera equipment 60, etc.

In addition, in the first embodiment described above, the camera device 60 is fixed to the lower peripheral wall 15 of the camera mounting box main body 10A, but it does not necessarily have to be fixed at this location, and it may be fixed to, for example, either the left or right peripheral wall 15 that does not open or close depending on the surrounding conditions.

In addition, the cable inlet 30 in the lower peripheral wall 15 in each of the above embodiments is composed of a lock nut 31 and a cap 32, but is not limited to this configuration, and the opening may be left unclosed. And, although the cable inlet 30 is provided in two places in the lower peripheral wall 15, the number of places is not limited, and it may be provided in another peripheral wall 15, or may be provided in another peripheral wall 15.

Furthermore, the camera side cable passage hole 27 through which the camera side cable passes, which is provided in the camera mounting portion 12 of the lower peripheral wall 15, is blocked by attaching a bushing 29, but may be formed by a knockout or the like.

In addition, the camera equipment mounting box in each of the above embodiments is formed in a rectangular box shape, but it may also be formed in other shapes such as a circular box shape, an elliptical box shape, a hexagonal box shape, or an octagonal box shape.

In each of the above embodiments, the camera device 60 is shown to be installed on a building wall 80, a pole, or a pipe, but it can also be installed on other structures using the camera device mounting box of the present invention.
