(Fixation of mounting member 50 to fixed portion 13 of surveillance camera 1)
FIG. 6 is a perspective view showing how the mounting member 50 is mounted to the fixed portion 13 of the surveillance camera 1. As shown in FIG. FIG. 7 is a diagram showing an arrangement example of screw holes provided in the fixed portion 13. As shown in FIG. FIG. 8 is a diagram showing a modification of the arrangement of screw holes provided in the fixed portion 13. As shown in FIG.

As shown in FIG. 6 , the fixed portion 13 of the surveillance camera 1 has a concave portion 15 having a contour shape corresponding to the contour shape of the base portion 51 . As an example, the recess 15 is formed in the rear surface of the housing 11 of the surveillance camera 1 . The bottom surface of the concave portion 15 is formed as a flat surface for receiving the base portion 51, for example. The depth of the concave portion 15 is approximately the same as the thickness of the base portion 51, for example. The depth of the concave portion 15 may be shallower than the thickness of the base portion 51 or may be deeper than the thickness of the base portion 51 .

Specifically, the concave portion 15 has a circular contour shape that is one size larger than the contour shape of the base portion 51 . The recess 15 is preferably of a size that is not too large relative to the base portion 51 and that the base portion 51 fits into the recess 15 when the base portion 51 is inserted into the recess 15 . With such a configuration, the mounting member 50 is stably fixed by the recess 15 .

As shown in FIG. 7, the recess 15 is formed with a first screw hole group 16A including a pair of screw holes 16a and a second screw hole group 16B including a pair of screw holes 16b. The pair of screw holes 16a of the first screw hole group 16A are formed so as to line up in the left-right direction. 16 A of 1st screw hole groups are for attaching the attachment member 50 to the fixing|fixed part 13 in a 1st attitude|position. The pair of screw holes 16b of the second screw hole group 16B are formed so as to line up in the vertical direction orthogonal to the horizontal direction. The second screw hole group 16B is for attaching the mounting member 50 to the fixing portion 13 in the second posture. By forming the first screw hole group 16A and the second screw hole group 16B in the concave portion 15 in this manner, the mounting member 50 can be mounted in different orientations with respect to the surveillance camera 1 . This means that the mounting member 50 can support the surveillance camera 1 in a first orientation and a second orientation perpendicular to the first orientation.

Although FIGS. 6 and 7 show only two of the first screw hole group 16A and the second screw hole group 16B, more screw hole groups may be provided. In the concave portion 15' of FIG. 8, two pairs of screw holes 16c are formed on a reference line that intersects the horizontal reference line at +45° and -45°.

(Connection between attachment member 50 and mount member 20)
9 is an enlarged view showing an enlarged part of FIG. 2. FIG. In FIG. 9, illustration of the fixture 30 is omitted. FIG. 10 is an enlarged view showing a state in which the mounting member 50 is rotated by a predetermined angle with respect to the mounting member 20. As shown in FIG.

In the configuration of this embodiment, the head portion 61 of the fixing screw 60 is inserted into the space Sa between the base portion 51 and the projecting portion 26 while the mounting member 50 is connected to the mounting member 20 as shown in FIG. To position. As shown in FIG. 9(a), the fixing screw 60 is provided at a position such that the center axis of the fixing screw 60 coincides with the reference line L passing through the center of the through hole 26h. A distance da between the head portion 61 of the fixing screw 60 and the projecting portion 26 is formed shorter than the length db of the shaft portion 62 of the fixing screw 60 . In this embodiment, two fixing screws 60 are provided, but since the peripheral structure of each fixing screw 60 is provided in the same manner, redundant description will be omitted.

The distance da between the head 61 of the fixing screw 60 and the projecting portion 26 can be set as appropriate. and preferably less than the distance the fixing screw 60 travels axially in one revolution of the fixing screw 60 . With such a configuration, even if the fixing screw 60 is loosened from the fixing part 13 of the monitoring camera 1 and moves away from the fixing part 13 (see the arrow direction in FIG. 9), the head 61 of the fixing screw 60 is Since the movable range of the fixing screw 60 in the axial direction is restricted by abutting on the protruding part 26, the shaft part 62 does not slip out of the through hole 51h, and thus the fixing screw 60 does not drop out of the base part 51.例文帳に追加

The condition of the distance da as described above is always satisfied within the movable range of the mounting member 50 forming the predetermined angles +θ° and −θ° with respect to the reference line L of the mounting member 20, as shown in FIG. preferably The predetermined angles +θ° and −θ° may be +90° and −90°, for example. Thus, the head 61 of the fixing screw 60 is always positioned between the base portion 51 and the projecting portion 26 within a movable range of +90° and −90° with respect to the reference line L, and When the distance da is shorter than the length of the shaft portion 62 of the fixing screw 60 , the fixing screw 60 is positioned from the base portion 51 of the fixing screw 60 regardless of the orientation of the mounting member 50 within the movable range of the mounting member 50 . You can prevent it from coming off.

(Fixation of surveillance camera 1 by mounting structure 5)
An example of a procedure for fixing the monitoring camera 1 to the installation site S using the mounting structure 5 and the mounting mechanism 2 configured as described above will be described below.

First, the user fits the base portion 51 of the mounting member 50 into the concave portion 15 of the fixing portion 13 of the surveillance camera 1 and tightens the two fixing screws 60 in that state. The fixing screw 60 may be screwed into either the first screw hole group 16A or the second screw hole group 16B. 16a.

Next, the user fixes the mounting member 20 of the mounting mechanism 2 to the installation location S. As shown in FIG. The user fixes the mount member 20 to the installation location S by attaching the base portion 21 of the mount member 20 to the installation location S using, for example, a screw, a nail, or an adhesive.

Next, the user connects the mounting member 50 fixed to the fixed portion 13 of the monitoring camera 1 and the mounting member 20 fixed to the installation location S. As shown in FIG. Specifically, the user inserts each insertion portion 52 of the mounting member 50 into the gap between the projecting portions 26 of the mount member 20 . With the insertion portion 52 inserted to a predetermined position and the through hole 52h of the insertion portion 52 and the through hole 26h of the projecting portion 26 aligned, the user fixes the through hole 52h and the through hole 26h. The shaft portion 31a of the rod 31 is inserted.

With the fixed rod 31 thus inserted, the mounting member 50 is rotatable about the shaft portion 31 a of the fixed rod 31 with respect to the mount member 20 . The user tightens the fixing rod 31 after adjusting the orientation of the monitoring camera 1 to a desired orientation. As a result, the monitoring camera 1 is attached to the installation location S. As shown in FIG.

Finally, the user connects the wiring 19 to the wiring connection section 14 of the surveillance camera 1 . Installation of the monitoring camera 1 at the installation location S is completed through the series of steps described above.

(Effect)
According to the configuration of the present embodiment as described above, the movable range of the fixing screw 60 in the axial direction is limited when the mounting member 50 is connected to the mounting member 20. Even if the fixing screw 60 is loosened from the fixing part 13 of the monitoring camera 1, the fixing screw 60 does not come off from the base part 51.例文帳に追加Therefore, the monitoring camera 1 does not come off the mounting member 50 and fall.

Furthermore, in this embodiment, the distance da between the head 61 of the fixing screw 60 and the projecting portion 26 is set shorter than the distance the fixing screw 60 advances in the axial direction when the fixing screw 60 is rotated twice. ing. According to such a configuration, even if the fixing screw 60 is loosened, the head 61 of the fixing screw 60 comes into contact with the projecting portion 26 when the fixing screw 60 rotates twice, and the fixing screw 60 does not turn any further. Therefore, the fixing screw 60 is prevented from loosening significantly, and as a result, the orientation of the surveillance camera 1 is prevented from changing significantly.

In the configuration of this embodiment, the fixed portion 13 of the monitoring camera 1 is formed with a first screw hole group 16A and a second screw hole group 16B. By providing a plurality of screw hole groups in this manner, the orientation of the mounting member 50 can be changed, and therefore the mounting orientation of the monitoring camera 1 can be changed.

In the configuration of this embodiment, the housing 11 of the monitoring camera 1 has the fixing portion 13 and the wiring connection portion 14 on the side opposite to the side on which the imaging device 18 is arranged. With such a configuration, the wiring 19 is not located on the imaging device 18 side. When the wiring 19 is located on the side of the imaging device 18, for example, a worker performing a predetermined work near the monitoring camera 1 may touch the wiring 19 unintentionally, and the direction of the monitoring camera 1 may change. However, according to the configuration of this embodiment, such a problem does not occur.

Also, the direction of the monitoring camera 1 can be changed with the vicinity of the fixed portion 13 as the center. In the case of such a configuration, when the orientation of the monitoring camera 1 is changed, the amount of movement of the front side of the monitoring camera 1 is larger than that of the rear side. Therefore, in the configuration in which the wiring 19 is connected to the front side of the monitoring camera 1, it is necessary to secure the wiring 19 having a sufficient length so that the direction of the monitoring camera 1 can be changed. There is no such need according to
