Abstract

PURPOSE: To enhance the workability by forming a camera mount base assembly through the installation of a camera mount base projected from a rear side escutcheon of a mount base so as to avoid a limit in an installed location by an open/closing space of the device. CONSTITUTION: A screw 30 is threaded from the out side of a holding part 28 as an engagement projection to a thread hole 29 formed to the lower end of the holding part 28 of a guide holding metallic fixture 27 and a tip of the screw 30 is engaged with a groove 15 when the holding part 28 holds the guide section 14 to be a turning means 38. A case assembly 8 is mounted to a camera mount base assembly 5 while the base 4 is inserted to the inside of the case 6 and the rear edge of the case 6 is in close contact with the rear end escutcheon 3. A link rod 9 and the screw 10 are threaded together as a fixing means from the front side of the assembly 8 to the assembly 5. When the assembly 8 is extracted to the front side, the screw 30 is in press contact with the front end of the groove 15 and the assembly 8 is turned downward around the screw 30.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing device for housing a surveillance camera.

[0002]

2. Description of the Related Art As a conventional surveillance camera housing device, there is one shown in FIGS.
The surveillance camera housing device 50 includes a base 51 on which a surveillance camera (not shown) is mounted, and front and rear escutcheons 52 and 5 provided on the front and rear of the base 51.
3 and a pair of side plates 55 attached to the left and right sides of the base 51 by hinges 54.

The left and right sides of the front escutcheon 52 and the rear escutcheon 53 are formed to extend to form side plate mounting portions 52a and 53a. This side plate attachment part 5
Screw holes 52b and 53b are formed in 2a and 53a, respectively.

The side plate 55 has a side surface portion 55a and an upper surface portion 55b, and an end portion of the upper surface portion 55b is bent upward to form a joint portion 55c. Further, the side surface 55a has a screw hole 55d so that the side plate 55 is overlapped with the screw holes 52b and 53b when the side plate 55 is brought into contact with the side plate mounting portions 52a and 53a.
And a side plate mounting screw 56 is screwed into the screw holes 52b and 53b and the screw hole 55d.

In the conventional surveillance camera housing device 50 constructed as described above, when the surveillance camera is to be mounted inside, the side plate mounting screws 56 are loosened and the hinge 54 is attached.
The side plate 55 was opened to the left and right around the axis, and the surveillance camera could be attached to the base 51.

After the mounting, the side plate mounting screws 56 are tightened in the screw holes 52b and 53b and the screw hole 55d in a state where the joint portions 55c of the left and right side plates 55 are in close contact with each other to seal the surveillance camera housing device 50. .

[0007]

However, in the above-mentioned conventional device, a space for opening and closing the side plates 55 is required on the left and right sides of the surveillance camera housing device 50 when the surveillance camera is mounted. Therefore, it has been an obstacle to space saving around the installation location of the surveillance camera housing device 50. In addition, the surveillance camera housing device 5
The installation place of 0 was also limited to a place without obstacles on the left and right sides of the housing device.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a surveillance camera housing device whose installation location is not limited by the space required for opening and closing.

[0009]

In order to achieve the above object, the present invention provides a camera mounting base assembly comprising a rear escutcheon mounted on a mounting base and a camera mounting base projecting from the rear escutcheon.
A front escutcheon having a window is attached to one opening of the cylindrical case, and a case assembly detachably attached to the camera mounting base assembly so as to cover the case and one end of the camera mounting base assembly. Rotating means configured by rotatably engaging one provided engaging portion and the other engaging portion provided at the other end of the case assembly, and the case assembly to the camera mounting base assembly. It is composed of a fixing means for detachably fixing.

[0010] Preferably, the rotating means is formed with an engaging groove having a closed end at one end of the mounting base and an open end at the other end, and an engaging projection for engaging the engaging groove in the case assembly. May be formed to configure the rotating means.

[0011]

With this configuration, the case assembly is attached and detached on the front escutcheon mounting side. In other words, the case assembly is attached to and detached from the surveillance camera in the shooting direction. Normally, the surveillance camera and the subject are installed at a certain distance from each other. However, objects do not exist close to each other. For this reason, the case assembly and surrounding objects do not interfere with each other when the case assembly is attached or detached.

Further, when the case assembly is detached, one engaging portion of the camera mounting base assembly engages with the other engaging portion of the case assembly, and the case assembly is attached to the camera mounting base assembly. Since it rotates with respect to the camera assembly, the surveillance camera can be attached to the base while the case assembly is held by the camera attachment base assembly.

Further, in the present invention, when the case assembly is pulled out, the engaging projection is engaged with the engaging groove formed in the mounting base, so that the mounting can be performed without dropping the case from the mounting base. It can be moved to the underside of the table, and a sufficient space for work can be secured.

The mount 2, the rear escutcheon 3 and the base 4 are the escutcheon mounting portion 1 of the mount 2.
3, the bottom portion of the rear escutcheon 3 is overlaid, and the screw 24 is screwed into each of the screw holes 12, 17, 23 with the rear end portion of the fitting 21 being overlaid on the inner surface of the bottom portion.
The camera mounting base assembly 5 is integrally formed.

Next, the case 6 and the front escutcheon 7 constituting the case assembly 8 will be described.

The case 6 is a tubular member having a square opening cross section, a screw hole 31 is formed at the front edge of the case 6, and a tubular shape penetrating from the front end to the rear end is formed in the upper part of the case 6. Connecting rod through hole 25 is formed. Further, a screw hole 26 is formed at the front end of the bottom surface of the case 6, and a pair of guide portion holding fittings 27 are fixed to the rear end of the bottom surface.

The guide portion holding metal fitting 27 is provided with holding portions 28, and the distance between the holding portions 28 is set to the guide portion 14.
Is adjusted so as to slidably hold the holding portion 2
A screw hole 29 is formed in the lower end portion of 8. The screw hole 29 is provided as an engaging protrusion from the outside of the holding portion 28 with the screw 3
0 is screwed, and the tip of this screw 30 is the holding portion 28.
When the guide portion 14 is held, it engages with the engaging groove 15 and becomes the rotating means 38.

Like the rear escutcheon 3, the front escutcheon 7 is formed in a box shape with one surface opened.
A window 32 is formed in the center. A glass 33 is attached to the back side of the window 32. A plurality of screw holes 34, 35, 36 are formed on the front surface, of which the screw holes 34 overlap the screw holes 31.
A screw 37 is screwed to 31 and the front escutcheon 7 is fixed to the case 6 to be integrated as a case assembly 8.

The case assembly 8 is mounted on the camera mounting base assembly 5 with the base 4 inserted into the case 6 and the rear edge of the case 6 being in close contact with the rear escutcheon 3. At this time, the connecting rod 9
