When the dome-type surveillance camera body 2 and the ceiling mounting jig 3 are unfixed while the wire 4 is housed in the wire housing part 19, the dome-type surveillance camera body 2 falls due to gravity, and the fall The bulging portion 6 cannot pass through the slit 13 and remains in the wire accommodating portion 19 which is the lowest point of the wire attaching portion 5. As a result, the dome-type surveillance camera main body 2 falls by the length of the wire 4 and is supported by the wire mounting portion 5 in a state where the wire 4 is in a straight line, thereby avoiding dropping on the floor.

  Furthermore, even when an external force in a direction other than the gravity direction is applied to the ceiling-mounted surveillance camera 1 and the wire 4 moves in a direction other than the gravity direction, the wire 4 attaches the dome-type surveillance camera main body 2 to the ceiling in the wire mounting portion 5. In order to move to the insertion hole 12 from the wire accommodating portion 19 which is a stationary position attached to the jig 3, the bending portion 14, the branch portion 15, and the terminal portion 17 are provided, and a plurality of different directions are provided. Since it is necessary to pass through the straight portions (L20, L19, L18), it is necessary to move in multiple directions, and the bulging portion 6 does not easily protrude from the insertion hole 12 easily.

(Seventh embodiment)
As shown in FIG. 10, the wire attachment portion 5, which is an opening formed by pressing a metal plate or the like, has an insertion hole 12 drilled in a shape through which the bulging portion 6 of the wire 4 can pass, While being open to the hole 12 and allowing the wire 4 to pass therethrough, the bulging portion 6 is located at the opposite end to the insertion hole 12 in the slit 13 and the slit 13 formed in the width W1 so as not to pass, The width W2 is wider than the slit 13, and the bulging portion 6 is composed of a second wire housing portion 23 formed in a width that cannot pass.
The insertion hole 12 is located farthest from the dome-type monitoring camera main body 2 in a state where the dome-type monitoring camera main body 2 and the ceiling mounting jig 3 are fixed. It is in the position closest to the camera body 2.
Here, the shortest locus when the wire 4 moves from the insertion hole 12 to the second wire accommodating portion 23 is defined as a wire movement path KL.
The wire movement path KL passes from the insertion hole 12 through the slit 13 to the second wire housing portion 23 in the direction of the dome-type monitoring camera body 2.
In a state where the dome-type surveillance camera body 2 is attached to the ceiling mounting jig 3, the bulging portion 6 and the wire 4 connected to the bulging portion 6 pass through the slit 13 from the insertion hole 12 due to gravity, and thus the second wire accommodating portion 23. Therefore, the bulging portion 6 is in the second wire accommodating portion 23 closest to the dome-type surveillance camera main body portion 2.

  When the dome type surveillance camera body 2 and the ceiling mounting jig 3 are unfixed while the wire 4 is accommodated in the second wire housing part 23, the dome type surveillance camera body 2 falls due to gravity, and the fall Accordingly, the bulging portion 6 cannot pass through the slit 13 and remains in the second wire housing portion 23 that is the lowest point of the wire attachment portion 5. As a result, the dome-type surveillance camera main body 2 falls by the length of the wire 4 and is supported by the wire mounting portion 5 in a state where the wire 4 is in a straight line, thereby avoiding dropping on the floor.

  Furthermore, even when a force other than the direction of gravity is applied to the ceiling-mounted surveillance camera 1 and the wire 4 moves in a direction other than the direction of gravity, the wire mounting portion 5 is inserted into the width W2 of the second wire housing portion 23. Since the width W <b> 1 of the slit 13 on the side of the hole 12 is narrow, the bulging portion 6 does not easily protrude from the insertion hole 12 easily.

(Eighth embodiment)
As shown in FIG. 11, the wire attachment portion 5, which is an opening formed by pressing a metal plate or the like, has an insertion hole 12 drilled in a shape through which the bulging portion 6 of the wire 4 can pass, and insertion A slit 13 formed in a width W1 that opens to the hole 12 and allows the wire 4 to pass therethrough but cannot pass the bulging portion 6, and the dome-type surveillance camera main body 2 in the slit 13 closest to the slit 13 A narrow portion 24 that gradually decreases in width as it approaches the dome-shaped surveillance camera body 2 formed on the dome-shaped surveillance camera body 2, and a narrow portion 24 that is formed closest to the dome-shaped surveillance camera body 2 in the narrow portion 24. The third wire accommodating portion 25 has a width W4 that is much wider than the width W3 of the narrowest portion 24a.
Here, the width of the widest portion 24 b of the narrow portion 24 is the same as the width W 1 of the slit 13, and the width W 3 of the narrowest portion 24 a of the narrow portion 24 is at least wider than the width of the wire 4.
Furthermore, the width W4 of the third wire housing portion 25 is larger than the width W3 of the narrowest portion 24b of the narrow portion 24 and is a size that the bulging portion 5 does not pass through. More preferably, it is wider than the width W1 of the slit 13 and does not allow the bulging portion 5 to pass.

Here, the insertion hole 12 is at a position farthest from the dome-type monitoring camera main body 2 in a state where the dome-type monitoring camera main body 2 and the ceiling mounting jig 3 are fixed. It is in the position closest to the dome-type surveillance camera body 2.
The shortest locus when the bulging portion 6 is inserted into the insertion hole 12 and the wire 4 moves from the insertion hole 12 to the third wire housing portion 25 is defined as a wire movement path KL.
The wire movement path KL passes from the insertion hole 12 through the narrow portion 24 to the third wire housing portion 25 in the direction of the dome-type monitoring camera body 2.
In the state where the dome-type surveillance camera body 2 is attached to the ceiling mounting jig 3, the bulging portion 6 and the wire 4 connected to the bulging portion 6 pass through the narrow portion 24 from the insertion hole 12 by gravity and accommodate the third wire. In order to move to the part 25, the bulging part 6 is in the third wire housing part 25 closest to the dome-type surveillance camera body part 2.

  When the dome-type surveillance camera body 2 and the ceiling mounting jig 3 are unfixed while the wire 4 is housed in the third wire housing part 25, the dome-type surveillance camera body 2 falls due to gravity, and the fall Accordingly, the bulging portion 6 cannot pass through the slit 13 and remains in the third wire housing portion 25 that is the lowest point of the wire attachment portion 5. As a result, the dome-type surveillance camera main body 2 falls by the length of the wire 4 and is supported by the wire mounting portion 5 in a state where the wire 4 is in a straight line, thereby avoiding dropping on the floor.

  Furthermore, even if an external force other than the direction of gravity is applied to the ceiling-mounted surveillance camera 1, the wire 4 moves in a direction other than the direction of gravity, and the wire 4 rises from the third wire housing portion 25, the wire mounting portion 5 Since the width W3 of the narrowest portion 24b of the narrow portion 24 is much narrower than the width W4 of the third wire housing portion 25, the wire 4 does not come out of the third wire housing portion 25 and swells from the insertion hole 12. The possibility that the protruding portion 6 jumps out is low.

In the first to eighth embodiments, the ceiling-mounted surveillance camera 1 is described as a representative example, but the ceiling-mounted surveillance camera 1 is not limited to the ceiling-mounted surveillance camera 1, Needless to say, the present invention is also effective for ceiling-suspended instruments such as exhaust ducts.
The material of the wire 4 (string portion) is optimally metal, but in the case of the present embodiment, any material having strength that does not break even when the ceiling-mounted surveillance camera is suspended may be used. Further, instead of the wire 4, a chain, a rope, or the like may be used. Further, it is desirable that the length of the wire 4 is short enough not to impair workability when the dome-type surveillance camera body 2 is attached to the ceiling mounting jig 3.

Also, as shown in FIGS. 3, 4, and 9, by setting the corners of the bent portions 14, 16, 21, and 22 close to the dome-type surveillance camera body 2 to the corner R, the wires are wired. You may make it easy to guide to the accommodating parts 19,23,25.
Furthermore, it is desirable for the branch portions 15 and 18 shown in FIGS. 3, 4, 7, 8, and 9 to branch in an antigravity direction that is 180 degrees different from the gravity direction. It is not necessary to make this angle, and the angle may be divided into two directions: an angle closer to the gravitational direction than the direction orthogonal to gravity and an angle closer to the antigravity direction than the direction orthogonal to gravity.

As described above, when the second member is attached from the ground side in the direction of gravity to the first member attached to the structure such as the ceiling, the first and second members are fixed. In a member connection structure that prevents separation beyond a distance, a wire 4 having one end fixed to a second member and having a bulging portion 6 at the other end, and an insertion formed in a shape through which the bulging portion 6 can pass The wire 4 can be easily provided by including the hole 12 and the wire attachment portion 5 having a slit 13 formed with a width that opens to the insertion hole 12 and prohibits the passage of the bulging portion 6 and allows the passage of the wire 4. Can be attached to the wire attaching portion 5, and the burden on the attaching operator is reduced.
Furthermore, even when the force which separates the 1st and 2nd member acts, it can prevent that a 2nd member falls by the wire 4 removing from the wire attachment part 5. FIG.
Furthermore, since the structure of the wire attachment part 5 has at least one of a bent part, a branch part, a terminal part, and a narrow part, even when a force other than the direction of gravity is applied to the wire 4, the wire attachment part The wire 4 is no longer detached from 5.
Furthermore, since the ceiling mounting device of the present invention is composed of the wire 4 and the wire mounting portion 5, the space required for mounting can be significantly reduced as compared with the conventional case.
