More specifically, the present invention relates to a technique that can easily fix image pickup devices of various sizes.

  As an imaging device, for example, there is a surveillance dome type video camera installed on the ceiling or wall of a building. This dome-type video camera is installed for the purpose of ensuring safety and improving serviceability in hospitals, hotels, department stores, etc., and monitors the captured images. That is, an optical block constituted by a lens and an imaging block constituted by an imaging element are accommodated in a lens barrel, and the lens barrel is horizontally (hereinafter referred to as “pan direction”) and vertical direction (hereinafter referred to as “ It is attached so that it can rotate in the “tilt direction”), and the outer periphery of the movable region of the lens barrel is covered with a dome-shaped cover. And the imaging signal from an imaging block is connected to the monitor of a monitoring room by a coaxial cable.

  Here, in order to install such a dome type video camera, a coaxial cable is connected to the back surface, and then fixed to the ceiling or wall of the building with an embedded metal fitting. Next, the lens is adjusted to a predetermined orientation (direction and angle) by the angle adjustment mechanism of the lens barrel, and the focus and zoom of the lens are set.

FIG. 6 is a cross-sectional view showing a state in which the dome-type video camera 10 is attached to the ceiling 130 with the conventional embedded metal fittings 200 and 300, and FIG. 6 (a) shows the embedded metal fitting 200 described in Patent Document 1 above. FIG. 6B shows another conventional embedded metal fitting 300.
As shown in FIG. 6, the dome type video camera 10 is attached to the ceiling 130 using the embedded metal fittings 200 and 300. That is, the bracket 110 is attached to the pedestal 40, and the ceiling 130 is sandwiched and fixed by the embedded metal fittings 200 and 300 provided around the bracket 110. Then, after adjusting the angle of the lens barrel 50, the embedded metal fittings 200, 300 are covered with the lid 120.

  Here, the embedded metal fitting 200 shown in FIG. 6A has an L-shaped metal fitting body 201 having a portion extending in the radial direction and a portion extending in the vertical direction with respect to the base 40 (bracket 110). A fixing screw 202 is rotatably attached to the metal fitting body 201, and a fixing member 205 is screwed into the fixing screw 202. When the fixing screw 202 is rotated, the fixing member 205 is rotated by 90 ° to 180 ° in the rotation direction, and thereafter, the fixing member 205 is reciprocated according to the tightening direction or the loosening direction of the fixing screw 202. ing.

  In order to fix the dome type video camera 10 to the ceiling 130 with such an embedded metal fitting 200, first, the fixing member 205 is first rotated (90 ° to 180 °) so as to face inward toward the base 40. The fixing member 205 is made so as not to interfere with the embedding. Then, after the base 40 and the bracket 110 of the dome type video camera 10 to which the embedded metal fitting 200 is attached are embedded in the opening of the ceiling 130, the fixing screw 202 is rotated in the tightening direction, and the fixing member 205 is moved in the radial direction of the base 40. Inverted (90 ° to 180 °) to face outward. Thereafter, when the fixing screw 202 is further screwed in, the fixing member 205 moves so as to approach the ceiling 130. Therefore, the ceiling 130 is sandwiched between the metal fitting body 201 (the L-shaped portion extending in the radial direction) and the fixing member 205, and the dome type video camera 10 is fixed.

  Further, in order to fix the dome type video camera 10 by the embedded metal fitting 300 shown in FIG. 6B, first, the fixing screw 302 is loosened, the portion extending in the radial direction of the metal fitting body 301, the fixing member 305, Make sure that there is sufficient opening between them. Then, while tilting the embedded metal fitting 300, the ceiling 130 enters between the fixing member 305 and the portion extending in the radial direction of the metal fitting body 301. Thereafter, the bracket 110 fixed to the pedestal 40 of the dome type video camera 10 is attached to the metal fitting body 301 and the fixing screw 302 is screwed. Then, since the fixing member 305 moves so as to approach the ceiling 130, the ceiling 130 is sandwiched between the metal fitting body 301 (the L-shaped portion extending in the radial direction) and the fixing member 305, and the dome type video camera 10 is fixed. Is done.

  However, the conventional embedded metal fittings 200 and 300 shown in FIG. 6 have a problem that it takes time to fix the dome type video camera 10. That is, in the embedded metal fitting 200 shown in FIG. 6A, it is necessary to first rotate the fixing member 205 so as to face inward toward the base 40, but for some reason the fixing screw 202 rotates. As a result, the fixing member 205 changes outwardly to some extent. Then, when the dome type video camera 10 is embedded, the fixing member 205 has to be performed again inward.

  The dome type video camera 10 has various sizes (differences in the height of the pedestal 40, etc.). When the fixed member 205 is rotated, the fixed member 205 and the pedestal 40 (or the bracket 110). May cause the fixing member 205 to be inward, so that it is necessary to prepare the embedded metal fittings 200 of various sizes in accordance with the dome type video camera 10 so that the interference does not occur.

  On the other hand, in the embedded metal fitting 300 shown in FIG. 6B, the ceiling 130 has to be inserted between the fixing member 305 and the portion extending in the radial direction of the metal fitting body 301 while tilting the embedded metal fitting 300, and thereafter Since the bracket 110 is attached to the metal fitting body 301, the workability is very poor. In particular, since fixing the dome type video camera 10 to the ceiling 130 has to work upward, a technique that can be easily fixed and can be embedded in various sizes of the dome type video camera 10 is required. Yes.

  Therefore, the problem to be solved by the present invention is to embed an imaging device of various sizes (for example, a dome type video camera) in an opening such as a ceiling or a wall so that it can be easily fixed.

The present invention solves the above-described problems by the following means.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In the following embodiments, a monitoring dome type video camera 10 is taken as an example of an imaging device. The dome type video camera 10 is installed on a ceiling 130 of a hospital, a hotel, a department store, etc. for the purpose of ensuring safety and improving serviceability, etc., and performs monitoring with a photographed image. The embedded metal fitting 100 of the present embodiment is for fixing such a dome type video camera 10 by being embedded in the ceiling 130.

FIG. 1 is an external view showing a dome type video camera 10 fixed to a ceiling by an embedding metal fitting 100 of the present embodiment to be described later. FIG. 1A is a side view of the dome type video camera 10, and FIG. b) is a perspective view thereof.
As shown in FIG. 1, the dome-type video camera 10 has an appearance in which a dome-shaped (hemispherical) cover 20 is attached to a case 30 and is installed with a pedestal 40 side facing a ceiling 130 (not shown). To do. That is, when installed on the ceiling 130, the cover 20 faces downward and the pedestal 40 is located on the upper side, contrary to the direction shown in FIG.

  Here, the cover 20 is a molded product (acrylic resin injection-molded product) having optical transparency. In other words, by using an acrylic resin, the optical refractive index is 1.5, the light transmittance is as high as 90% or more, and it can be close to an optical lens, and a precise mirror finish is achieved by injection molding. Can do. The dome video camera 10 generally finishes the cover 20 to be translucent so that imaging can be performed while not being noticed as much as possible. For example, carbon material is mixed during injection molding, and the light transmittance is adjusted to make a smoke finish, or the surface is coated with metal powder such as aluminum to make a half mirror finish, and the light transmittance, light reflectance, and The light absorption rate is about 33%.

  The case 30 is a molded product (molded product such as ABS resin) and is formed in a cylindrical shape. The cover 20 is detachably attached to the case 30. That is, three protruding pieces (not shown) are formed at equal intervals of 120 ° on the circular peripheral edge of the cover 20, and the case 30 has three cutting pieces corresponding to the protruding pieces. A notch (not shown) is formed. Therefore, when the cover 20 is attached, the protruding pieces of the cover 20 are simultaneously inserted into the notches of the case 30 and the cover 20 is rotated. Will be held. On the other hand, in order to remove the cover 20 from the case 30, the cover 20 may be rotated in the opposite direction, and the protrusions may be pulled out from the notches, contrary to the attachment.

  Inside the cover 20 and the case 30, a lens barrel 50 (see FIG. 1A) containing a lens and an image sensor (for example, a CCD (Charge Coupled Devices) device) is disposed. The cylinder 50 is rotatably held on the pedestal 40. Therefore, if the cover 20 is removed from the case 30 and the lens barrel 50 is set to a desired direction and angle, a desired position can be monitored from the captured image. Further, by attaching the translucent cover 20 to the case 30, the lens barrel 50 can be hidden from view from the outside.

  The dome type video camera 10 including the cover 20 and the case 30 is fixed by embedding the pedestal 40 side in an opening of a ceiling 130 (not shown). That is, the pedestal 40 includes a disc-shaped base 41 die-cast with a metal such as an aluminum alloy. A bracket 110 (not shown) is fixed to the base 41, and the embedded metal fitting 100 of the present embodiment to be described later. (Not shown) is embedded in the ceiling 130. When the dome type video camera 10 is embedded and fixed, it is connected to the monitor in the monitoring room by a coaxial cable, but the coaxial cable is also embedded in the ceiling 130 and hidden from view from the outside.

2 is an external view showing the pedestal 40 and the lens barrel 50 in the dome type video camera 10 shown in FIG. 1, FIG. 2A is a side view of the pedestal 40 and the lens barrel 50, and FIG. FIG.
In the dome video camera 10 shown in FIG. 1, when the cover 20 and the case 30 are removed, the base 40 and the lens barrel 50 are exposed as shown in FIG.

  Here, the pedestal 40 is installed on the base 41 of the disk shape, the support member 42 on which the rotating sphere portion 52 of the lens barrel 50 is placed, and the rotating sphere portion 52 is accommodated so that the lens barrel 50 can be removed. And a cylindrical retaining member 43 for preventing the above. A circuit in which various electronic components for photoelectrically converting the light and darkness of the image formed on the imaging surface of the imaging element into the amount of electric charges and sequentially reading out and converting them into electric signals is mounted on the base 41. A substrate 60 is attached. The circuit board 60 functions as a signal processing board and a power supply board, and includes a monitor output terminal, a coaxial cable terminal, other switches, a volume, and the like.

  The support member 42 includes a disk-shaped movable plate 44 on which the rotating sphere portion 52 is placed and presses the rotating sphere portion 52 toward the retaining member 43, and a fixing screw 45 that reciprocates the movable plate 44. I have. The movable plate 44 is a peripheral portion of the movable plate 44 and rotates around a rotation shaft 46 provided on the support member 42, and the fixing screw 45 is attached to the support member 42 on the side opposite to the rotation shaft 46. It is provided and screwed into the peripheral edge of the movable plate 44.

  Therefore, when the fixing screw 45 is rotated clockwise (in the screwing direction), the movable plate 44 rotates around the rotation shaft 46 on one end side (rotates upward in FIG. 2), and the other end side is prevented from being removed. It moves toward the member 43. As a result, the rotating ball portion 52 placed on the movable plate 44 is pressed toward the retaining member 43. On the contrary, when the fixing screw 45 is rotated counterclockwise, the movable plate 44 is rotated backward (rotated downward in FIG. 2) around the rotation shaft 46 on one end side, and the other end side is moved to the base 41. Move towards.

  The lens barrel 50 can be rotated in the pan direction and the tilt direction by the rotating sphere 52, and the lens 71 can be set in a desired direction (direction and angle). That is, if the fixing screw 45 is rotated counterclockwise and the movable plate 44 is rotated toward the base 41, a gap is generated between the retaining member 43 and the rotating sphere 52, and the rotating sphere 52 Therefore, the lens barrel 50 can be freely rotated in the pan direction and the tilt direction.

  Further, when the fixing screw 45 is rotated clockwise and the movable plate 44 that is separated from the retaining member 43 is moved toward the retaining member 43 on the fixing screw 45 side, the stationary screw 45 is placed on the movable plate 44. The rotating ball portion 52 comes into contact with the retaining member 43 and is pressed. Therefore, the rotating ball portion 52 is pressure-bonded between the retaining member 43 and the movable plate 44, and the rotating ball portion 52 is fixed to the movable plate 44 without moving. As a result, the lens barrel 50 is fixed without moving in the adjusted pan direction and tilt direction, and the azimuth (direction and angle) of the lens 71 is accurately set.

  Accordingly, the lens 71 of the dome-type video camera 10 fixed to the ceiling 130 (not shown) is set in a desired direction, and the cover 20 is attached (state shown in FIG. 1) to image the desired position. It can be performed. Note that a focus ring 53 and a zoom lever 54 are attached to the lens barrel 50, and light from the imaging target can be imaged on the imaging surface of the imaging element with a desired size.

FIG. 3 is a cross-sectional view and a side view showing a state where the dome type video camera 10 shown in FIG. 1 is attached to the ceiling 130 by the embedded metal fitting 100 of the present embodiment.
As shown in FIG. 3, the dome type video camera 10 is attached to the ceiling 130 using the embedded metal fitting 100. That is, the bracket 110 is attached to the base 41 of the pedestal 40, the fixing member 105 of the embedded metal fitting 100 provided around the bracket 110 is moved toward the ceiling 130, and both front and back surfaces of the ceiling 130 are sandwiched and fixed. Then, the angle of the lens barrel 50 is adjusted as described above, and after the cover 20 is attached, the embedded metal fitting 100 and the like are covered with the lid 120.

4A and 4B are external views showing the embedded metal fitting 100 of the present embodiment. FIG. 4A is a perspective view of the embedded metal fitting 100, FIG. 4B is a front view thereof, and FIG. It is sectional drawing.
As shown in FIG. 4, the embedded metal fitting 100 includes a metal fitting body 101, a fixing screw 102, a moving member 103, a rotating shaft 104, a fixing member 105, and a spring material 106.

  Here, the metal fitting body 101 includes a holding portion 101a that holds the surface side of the ceiling 130 (see FIG. 3), a main body portion 101b that extends in a direction orthogonal to the holding portion 101a, and a restriction portion 101c that faces the holding portion 101a. ing. And the holding | maintenance part 101a is a flat plate-shaped thing which touches the surface side of the ceiling 130 planarly, and the main-body part 101b stands | starts up perpendicularly | vertically from one side of the holding | maintenance part 101a, and is a flat plate thing provided with the reinforcement rib on both sides The restricting portion 101c is an L-shape that is bent from the main body 101b on the opposite side of the holding portion 101a.

  The bracket 110 (see FIG. 3) can be attached to the metal fitting body 101 at a plurality of positions. That is, since the main body 101b can attach the bracket 110 to a plurality of positions between the holding portion 101a and the restricting portion 101c, the size (for example, the height of the base 40 shown in FIG. 3) changes. However, it is only necessary to change the mounting position of the bracket 110. Therefore, the embedded metal fitting 100 according to the present embodiment is a common unit that can cope with various types of dome video cameras 10 (see FIG. 3) having different sizes by simply replacing one type.

  Further, the fixing screw 102 is provided in parallel with the main body portion 101b so as to be rotatable between the holding portion 101a and the restricting portion 101c (an L-shaped portion parallel to the holding portion 101a). That is, the fixing screw 102 is passed from the holding portion 101a toward the restricting portion 101c so that the fixing screw 102 is not detached from the metal fitting body 101 with two nuts on the restricting portion 101c side. Therefore, the fixing screw 102 can move the moving member 103 by turning the head on the holding portion 101a side.

  The moving member 103 is L-shaped and is screwed into the fixing screw 102. Therefore, the holding screw 101 reciprocates between the holding portion 101a and the regulating portion 101c by forward and reverse rotation of the fixing screw 102. And the L-shaped part parallel to the main-body part 101b moves along the main-body part 101b, and is stored in the inside bent in the L-shape of the control part 101c on the control part 101c side.

  The moving member 103 is provided with a rotating shaft 104 in the direction orthogonal to the fixing screw 102. A fixed member 105 is attached to the rotating shaft 104. Therefore, the fixing member 105 rotates about the rotation shaft 104 by 90 ° from a state parallel to the main body 101b to a state parallel to the holding portion 101a. In addition, since the rotation shaft 104 is provided on the moving member 103, the fixed member 105 moves together with the moving member 103.

  Furthermore, the moving member 103 is provided with a spring material 106 that is passed through the rotating shaft 104. The spring material 106 is a torsion coil spring and urges the fixing member 105 to rotate in a direction parallel to the holding portion 101a. Note that the fixed member 105 rotated by the biasing force of the spring member 106 is held in a state parallel to the holding portion 101a, with the rotation range restricted by the moving member 103.

  Thus, the moving member 103 reciprocates by forward and reverse rotation of the fixing screw 102, and the fixing member 105 also moves together with the moving member 103. However, the fixing member 105 is attached to the spring member 106 at the restricting position by the restricting portion 101c. It rotates in a state parallel to the main body 101b against the force. That is, when the fixing member 105 that is parallel to the holding portion 101a by the urging of the spring material 106 moves toward the restricting portion 101c and contacts the tip end portion of the restricting portion 101c, the fixing member 105 resists the urging of the spring material 106. Will receive a pressing force. When the fixing member 105 is further moved toward the restricting portion 101c, the restricting position continues to be pressed by the tip of the restricting portion 101c, and the rotation center (rotating shaft 104) of the fixing member 105 and the pressing position of the restricting portion 101c are determined. The fixing member 105 is gradually rotated by the change in the relative positional relationship, and is finally folded to a state parallel to the main body 101 b and stored in the metal fitting body 101.

  On the other hand, when the fixing member 105 rotating in a state parallel to the main body 101b at the restriction position by the restriction portion 101c is moved toward the holding portion 101a, the rotation center (the rotation shaft 104) of the fixing member 105 is restricted. Since it is closer to the holding portion 101a than the tip portion (the pressing portion against the fixing member 105) of the portion 101c, the fixing member 105 is rotated so as to gradually rise by the bias of the spring material 106. And if it remove | deviates from the control position by the control part 101c, it will come to be controlled by the moving member 103 this time, and finally the rotation of the fixing member 105 will stop in the state parallel to the holding part 101a.

  In addition, after the fixing member 105 becomes parallel to the holding portion 101a, the fixing member 105 moves toward the holding portion 101a in that state, and the distance from the holding portion 101a is gradually narrowed. Therefore, the ceiling 130 (see FIG. 3) can be sandwiched between the fixing member 105 and the holding portion 101a, and the dome type video camera 10 (see FIG. 3) can be fixed.

FIG. 5 is a cross-sectional view showing the operation of the embedded metal fitting 100 of the present embodiment, and FIGS. 5A to 5D show the procedure for fixing the dome type video camera 10 (see FIG. 3) to the ceiling 130. ing.
As shown in FIG. 5, the embedded metal fitting 100 sandwiches the ceiling 130 from both the front and back surfaces, and embeds and fixes the pedestal 40 (see FIG. 3) side of the dome type video camera 10 in the opening of the ceiling 130. Accordingly, a specific method for embedding the dome-type video camera 10 using the embedding bracket 100 according to the present embodiment will be described below with reference to FIGS.

  FIG. 5A is a first stage of embedding the dome type video camera 10 (see FIG. 3), and shows a storage state of the fixing member 105. That is, at the restriction position (position shown in FIG. 5A) by the restriction portion 101c of the metal fitting body 101, the fixing member 105 is moved by the restriction portion 101c to the spring material from the relative positional relationship between the restriction portion 101c and the rotating shaft 104. It receives a pressing force against the urging of 106 and rotates until it becomes parallel to the main body 101b. Therefore, the fixing member 105 is stored in the metal fitting body 101 as shown in FIG. The stored fixing member 105 is positioned above the ceiling 130.

  In such a storage state of the fixing member 105, the fixing member 105 does not protrude when the dome type video camera 10 (see FIG. 3) is embedded, so that the pedestal 40 (see FIG. 3) side of the dome type video camera 10 faces the ceiling 130. It can be easily embedded in the opening. Then, as shown in FIG. 5A, the holding portion 101 a of the metal fitting body 101 is in contact with the surface side of the ceiling 130. If the fixing screw 102 is rotated clockwise (screwing direction) in this state, the moving member 103 moves toward the holding portion 101a.

  When the moving member 103 moves toward the holding portion 101a, the rotating shaft 104, the fixed member 105, and the spring material 106 move together with the moving member 103, as shown in FIG. Therefore, the relative positional relationship between the restricting portion 101c of the metal fitting body 101 (the tip portion of the restricting portion 101c that applies a pressing force to the fixing member 105) and the rotating shaft 104 changes, and the fixing member 105 is restricted by the restricting portion 101c. Since it comes out of position, the fixing member 105 is raised by the bias of the spring material 106. Then, by continuously rotating the fixing screw 102 in the clockwise direction (screwing direction), the fixing member 105 moves toward the holding portion 101a (ceiling 130) and rotates so as to be parallel to the holding portion 101a. .

  Such rotation of the fixing member 105 is stopped by the restriction of the moving member 103. That is, when the fixing member 105 is rotated until it is parallel to the holding portion 101 a of the metal fitting body 101, the upper surface of the fixing member 105 comes into contact with the moving member 103 as shown in FIG. Therefore, the rotation of the fixing member 105 urged by the spring material 106 is restricted and is held in a state parallel to the holding portion 101a. Then, when the fixing screw 102 is further rotated clockwise (in the screwing direction), the fixing member 105 remains in the state shown in FIG. 5C, via the moving member 103 and the rotating shaft 104, with the holding portion 101a ( Continue moving towards the ceiling 130).

  The fixing member 105 moved toward the holding unit 101a (ceiling 130) finally comes into contact with the back surface side of the ceiling 130 as shown in FIG. That is, both the front and back surfaces of the ceiling 130 are sandwiched between the holding portion 101a of the metal fitting body 101 and the fixing member 105. Therefore, when the fixing screw 102 is rotated clockwise (in the screwing direction), the holding portion 101a and the fixing member 105 tighten the ceiling 130, and thus the fixing of the dome type video camera 10 (see FIG. 3) is completed. In order to remove the dome type video camera 10, the reverse procedure may be followed.

  Thus, the embedded metal fitting 100 of the present embodiment can be easily fixed by embedding the dome type video camera 10 in the opening of the ceiling 130 or the like. Therefore, it is particularly suitable as an embedded metal fitting for a monitoring imaging device (for example, a dome type video camera) installed for the purpose of ensuring safety and improving serviceability in hospitals, hotels, department stores, and the like.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment. That is, in the present embodiment, the surveillance dome-type video camera 10 is taken as an example of the imaging device to be embedded and fixed. However, the present invention is not limited thereto. The pedestal side of an imaging device other than a camera or video camera can be embedded and fixed in the opening of the plate material.
