  According to Patent Document 1, the camera 201 can be rotated in the horizontal direction (pan direction) and the vertical direction (tilt direction). However, as a usage form of the monitoring camera device described in Patent Document 1, a configuration in which the surveillance camera device is installed on a desktop or the like or used on a ceiling or the like, that is, the device itself is in a horizontal state. It is limited to the form of installation and use, for example, it cannot be installed on a vertical wall surface or the like and used in a vertical state (a state directed in the lateral direction). In other words, when installed on a vertical wall or the like, the top and bottom direction of the photographed image cannot be secured, and when the tilt direction is adjusted, the top and bottom of the photographed image is slanted or reversed. There was a problem that it was very difficult to see as an image. Furthermore, since it cannot be installed and used on a vertical wall surface, there is a problem that the place of use is limited to the desktop or the ceiling.

  According to Patent Document 2, it is possible to secure the top-and-bottom direction of the TV camera 305 even when the installation location is inclined. This means that the top and bottom direction of the television camera 305 can be secured regardless of the direction in which the surveillance camera device is installed regardless of the horizontal direction and the vertical direction. However, in Patent Document 1, in order to secure such a top-and-bottom direction of the TV camera 305, the camera case 308 is removed, the fixing band 313 that fastens and fixes the turntable 312 is loosened, and the TV camera 305 is covered. Therefore, it is necessary to perform troublesome work such as adjusting the rotating base 312 while watching the video of a monitor (not shown) connected to the TV camera 305. Further, such a work is required every time the elevation angle of the television camera 305 is adjusted thereafter, and there is a problem that it is a very complicated work for the user.

  The present invention was devised to solve such problems, and its purpose is simple even if it is installed in a horizontal state on a tabletop or the like, or locked in a wall or the like and installed in a vertical state. An object of the present invention is to provide a surveillance camera device that can ensure the top-and-bottom direction of a photographed image by operation.

  The surveillance camera device of the present invention is used by installing a camera housed and held in a camera case body in a horizontal state on a desktop or the like via a fixed base, or by locking it to a wall surface or the like and installing it in a vertical state. It is a surveillance camera device. That is, the surveillance camera device is assumed to be used in any one of the two positions of the horizontal state and the vertical state. This surveillance camera device is connected to the camera case main body and can adjust the vertical elevation angle of the camera, and the vertical elevation rotation unit can be connected to the vertical elevation rotation unit and can rotate in the horizontal direction. And one end portion side of the horizontal rotation portion is fixed, and the other end portion is connected to the fixing base so as to be rotatable in one direction, the other end portion side of the arm member and the A first rotation position for vertically supporting the rotation axis of the horizontal rotating unit in a state in which the fixed base is installed in a horizontal state, and a state in which the fixed base is installed in a vertical state in a connection portion with the fixed base The position fixing means for fixing the arm member between the two rotation positions is provided at each of the second rotation positions for vertically supporting the rotation shaft of the horizontal rotation portion. It is characterized by not.

  With such a configuration, when the surveillance camera device is installed on a desktop or the like and used in a horizontal state, for example, the arm member is rotated to the first rotation position, and the first fixing is performed by the position fixing means. The arm member is fixed at the moving position. As a result, the rotation axis of the horizontal rotation unit can be supported vertically, so that even if the vertical elevation rotation unit is rotated in this state, the captured image is captured with the top-to-bottom direction secured. . Similarly, when the surveillance camera device is installed on, for example, a vertical wall surface and used in a vertical state, the arm member is rotated to the second rotation position, and the position fixing means is used at the second rotation position. Fix the arm member. As a result, the rotation axis of the horizontal rotation unit can be supported vertically, so that even if the vertical elevation rotation unit is rotated in this state, the captured image is captured with the top-to-bottom direction secured. . That is, according to the surveillance camera device of the present invention, the top-to-bottom direction of the captured image after the elevation angle adjustment is reliably ensured in both the horizontal state installed on the tabletop and the vertical state installed on the vertical wall surface. It becomes possible.

  In this case, the horizontal rotating portion includes a cylindrical rotating support fixed to one end of the arm member, and a cylindrical rotating body that rotates in the horizontal direction while being externally fitted to the rotating support. The rotation support body and the rotation body are provided with stopper means for restricting the rotation of the rotation body to a predetermined rotation angle range. The stopper means includes a first stopper means provided on the outer surface of the rotating support and the rotating body and a second stopper means provided on the inner surface of the rotating support and the rotating body. The first stopper means and the second stopper means are provided at positions that simultaneously restrict the rotation of the rotating body.

  If the rotation angle range of the camera in the horizontal direction, including the angle of view of the camera, can be secured within a rotation angle range of about 180 degrees, the entire room can be photographed. In this case, when a wide-angle lens of about 60 degrees is used as the angle of view of the camera, the rotation angle range may be about 60 degrees. Accordingly, in this case, the first stopper means is provided on the outer surface of the rotating support and the rotating body at an angle of about 60 degrees when viewed from the rotation center of the horizontal rotating portion, and the second stopper means is disposed horizontally. The rotating support and the inner surface of the rotating body are provided at an angle of about 60 degrees when viewed from the rotation center of the rotating portion. In this way, by providing the stoppers for regulating the rotation angle range in the horizontal direction at the two locations of the rotating support and the outer surface and the inner surface of the rotating member, stable rotation is controlled without rattling. be able to.

  Moreover, the rotating body which is a cylindrical member is usually formed of resin or the like by injection molding or the like. Therefore, there is also a problem in molding, and the rotating body having such a shape is usually divided into two parts on the left and right, and the rotating body is formed by assembling these divided bodies integrally. In this case, when the stopper means is provided only on the rotation support body and the inner surface of the rotation body, an excessive load is applied to the inside of the left and right divided bodies due to the rotation body hitting the stopper means many times. Therefore, there is a possibility that the divided body will be separated due to long-term use. However, as in the present invention, stopper means (first stopper means) are also provided on the rotating support and the outer surface of the rotating body. Thus, the problem that the divided bodies are separated can be solved. In particular, in the present invention, the first stopper means is configured to restrict the rotation so that both divided bodies are pressed against each other when the rotation of the rotating body is restricted. can do.

  Since the surveillance camera device of the present invention is configured as described above, the top-to-bottom direction of the captured image after adjusting the elevation angle can be set in either a horizontal state installed on a tabletop or a vertical state installed on a vertical wall surface. It can be surely secured. Moreover, since the stopper for restricting the rotation angle range in the horizontal direction is provided at the two locations of the rotation support body and the outer surface and the inner surface of the rotation body, stable rotation restriction can be performed without rattling. it can. Furthermore, when the rotating body is formed by integrally assembling the left and right divided bodies, a stopper for regulating the horizontal rotation angle range is provided on the rotating support body and the rotating body. Provided in two places on the outer side and inner side, and when the rotation of the rotating body is restricted, it is configured to restrict the rotation so that both divided bodies are pressed against each other. Therefore, it is possible to provide a surveillance camera apparatus that can be used for many years.

The rotation shaft 45 that is the rotation center P <b> 1 of the arm member 50 protrudes from the opposing surfaces 44 of both end portions in the longitudinal direction of the arm fitting portion 43 (upper end portion and lower end portion in FIG. 4). Is formed.

  Further, a pair of left and right guide pieces 46a and 46b that are concentrically curved with the rotation shaft 45 are formed on the facing surface 44 so as to protrude from the rotation surface 45 of the guide pieces 46a and 46b. Arm fixing groove portions 46a1 and 46b1 extending along the axial center direction of the rotating shaft 45 are formed at appropriate positions on the curved surface (guide surface) side. These arm fixing groove portions 46a1 and 46b1 are formed at positions at a certain angle (90 degrees in this example) with the rotation center P1 of the rotation shaft 45 as a vertex.

Further, a rectangular parallelepiped contact plate 55 is formed at the lower portion of the cylindrical rotating portion 52 at the center in the longitudinal direction, and at both ends in the longitudinal direction except for the contact plate 55 in the longitudinal direction. An arm fixing projection piece 56 extending along the axis is formed.

  FIG. 7 shows a state in which the fitting structure of the lower end portion 52 of the arm member 50 shown in FIG. 6 is fitted to the fitting structure on the fixing base 4 side shown in FIG.

  In other words, the annular recess 53 on the arm member 50 side is fitted into the rotation shaft 45 on the fixed base 4 side, and the arm member 50 can rotate about the rotation center P <b> 1 of the rotation shaft 45. It has become.

  Then, when the arm member 50 is rotated by an angle θ1 in the direction of the arrow Z1 in FIG. 7 from the state shown in FIG. 7, the one side surface 55b of the contact plate 55 contacts the inclined surface 47b and the rotation is restricted. At the same time, the arm fixing projection piece 56 is slidably contacted with the guide surface of the guide piece 46b, and is deformed and rotated so as to slightly expand the guide piece 46b, so that one side surface 55b of the contact plate 55 becomes an inclined surface 47b. When abutting, the arm fixing projection 56 is fitted into an arm fixing groove 46b1 formed in the guide piece 46b. That is, when the arm member 50 is rotated by an angle θ1 in the direction of the arrow Z1 in FIG. 7, the rotation is restricted by the one side surface 55b of the contact plate 55 coming into contact with the inclined surface 47b, and the arm fixing unit 50 When the protruding piece 56 is fitted into the arm fixing groove 46b1, the arm member 50 is fixed at the fitting position.

At the same time, the arm fixing projection 56 is slidably brought into contact with the guide surface of the guide piece 46a, and is deformed so as to slightly expand the guide piece 46a and is rotated. The other side surface 55a of the contact plate 55 is inclined surface 47a. The arm fixing projection 56 is fitted into an arm fixing groove 46a1 formed in the guide piece 46a. That is, when the arm member 50 is rotated by an angle θ1 in the direction of the arrow Z2 in FIG. 7, the other side surface 55a of the contact plate 55 is brought into contact with the inclined surface 47a, and the rotation is restricted and the arm is fixed. When the projecting piece 56 is fitted into the arm fixing groove 46a1, the arm member 50 is fixed at the fitting position. The rotation position of the arm member 50 at this time is the second rotation position described in the claims, and the arm member 50 in the state shown in FIG. 3 in which the monitoring camera device is vertically installed on a vertical wall surface or the like. It is a rotation position. As can be seen from FIGS. 1 and 3, the angle θ1 shown in FIG. 7 is 45 degrees, that is, the rotation angle range of the arm member 50 is 90 degrees (= θ1 + θ1). Further, the arm member 50 has a structure that does not fix the arm member 50 between the two rotation positions, although the arm fixing projection piece 56 rotates while being in sliding contact with the guide surfaces of the guide pieces 46a and 46b. Yes.

  Next, the structure of the horizontal rotation unit 20 will be described.

  As shown in FIG. 6, the horizontal rotating unit 20 rotates in the horizontal direction while being fitted on the rotating support 21 and a semicircular rotating support 21 formed on the upper end 51 of the arm member 50. And a cylindrical rotating body 22. As can be seen from FIG. 6, the horizontal rotating part 20 and the arm member 50 are divided into left and right parts, and formed by assembling each divided member (22a and 22b, 21a and 21b, 50a and 50b) integrally. Has been. Reference numeral 91 in the drawing denotes a fastening tool such as a bolt and a nut for assembling the divided members integrally.

The upper surface 23 of the rotary support 21, the short cylindrical protrusion 24, and the ring-shaped protrusion 25 form an annular sliding groove 26 whose longitudinal section is horizontally U-shaped. In addition, an annular sliding projection 27 projecting in the inner circumferential direction is formed on the lower end edge 26 of the cylindrical rotating body 22 that is externally fitted to the ring-shaped projection 25, and this annular sliding projection The part 27 is rotatable in a state where the part 27 is fitted in the annular sliding groove part 26.

  In such a rotating structure, one inner stopper member (small protrusion) 30a, 30b is formed at two positions on the upper surface of the ring-shaped protrusion 25 at a predetermined angle, and the rotation is opposed to this. On the inner peripheral surface of the body 22, the other inner stopper members (small protrusions) 31a and 31b are formed at two positions with a predetermined angle. These inner stopper members 30a, 31a, 30b, 31b constitute the second stopper means described in the claims.

  FIG. 9 shows the arrangement positions of the pair of inner stopper members 30a, 31a, 30b, 31b and the rotating body 22 rotated with respect to the rotating support 21 (that is, the annular sliding protrusion 27 is replaced with the annular sliding groove 26). It is explanatory drawing which shows an engagement position when it is made to rotate).

  The positional relationship shown in FIG. 9A is the positional relationship when the monitoring camera device 1 is in the state shown in FIG. 1, for example, that is, the camera case body 2 is facing the front. In this embodiment, in this state, the adjacent inner stopper members 30a, 31a, 30b, 31b are each formed to have a constant angle θ2 (60 degrees in this example) with the rotation center P2 as the apex.

  Then, from the state shown in FIG. 9A, when the rotator 22 is rotated by an angle θ2 in the direction of the arrow X1 in FIG. 9A, as shown in FIG. The other inner stopper member 31b formed is brought into contact with one inner stopper member 30b formed on the rotation support body 21 side, and the rotation is restricted. Although not shown, this state is a state in which the camera case body 2 shown in FIG. 1 is rotated 60 degrees to the right in the horizontal direction with respect to the fixed base 4.

  On the other hand, when the rotator 22 is rotated by an angle θ2 in the direction of the arrow X2 in FIG. 9A from the state shown in FIG. 9A, the rotator 22 is formed on the rotator 22 side as shown in FIG. 9C. The other inner stopper member 31a thus made abuts against one inner stopper member 30a formed on the rotation support member 21 side, and the rotation is restricted. Although not shown, this state is a state in which the camera case body 2 shown in FIG. 1 is rotated 60 degrees to the left in the horizontal direction with respect to the fixed base 4.

  As shown in FIG. 6, one outer stopper member 35, 36 is formed on the outer peripheral surface of the rotating body 22 at two opposing positions on the lower edge, and the other outer stopper is opposed to this. Members 37 and 38 are formed at two locations on the outer peripheral surface of the rotary support 21. However, the outer stopper member 38 is not shown in FIG.

  FIG. 10 shows the outer stopper members 35 and 36 formed at two locations on the outer peripheral surface of the rotating body 22. As described above, the rotating member 20 is divided into two parts on the left and right, and the outer stopper members 35 and 36 are also divided into two parts on the left and right (35a, 35b, 36a, 36b). Then, these are integrally assembled to form the outer stopper members 35 and 36.

  FIG. 11 shows the position of the pair of outer stopper members 35, 36, 37, and 38, and the rotating body 22 is rotated with respect to the rotating support 21 (that is, the annular sliding protrusion 27 is turned into the annular sliding groove 26. It is explanatory drawing which shows an engagement position when it is made to rotate).

  The positional relationship shown in FIG. 11A is a positional relationship when the monitoring camera device 1 is in the state shown in FIG. 1, for example, that is, the camera case body 2 is facing the front. In this embodiment, in this state, the adjacent outer stopper members 35, 37, 36, and 38 are each formed to have a constant angle θ2 (60 degrees in this example) with the rotation center P2 as a vertex.

  Then, from the state shown in FIG. 11 (a), when the rotator 22 is rotated by an angle θ2 in the direction of the arrow X1 in FIG. 11 (a), as shown in FIG. Each of the formed outer stopper members 35 and 36 is in contact with each of the other outer stopper members 38 and 37 formed on the rotation support body 21 side, and the rotation is restricted. Although not shown, this state is a state in which the camera case body 2 shown in FIG. 1 is rotated 60 degrees to the right in the horizontal direction with respect to the fixed base 4.

  On the other hand, when the rotating body 22 is rotated by an angle θ2 in the direction indicated by the arrow X2 in FIG. 11A from the state shown in FIG. 11A, the rotating body 22 is formed on the rotating body 22 side as shown in FIG. Each of the outer stopper members 35 and 36 thus made abuts against the other outer stopper members 37 and 38 formed on the rotation support body 21 side, and the rotation is restricted. Although not shown, this state is a state in which the camera case body 2 shown in FIG. 1 is rotated 60 degrees to the left in the horizontal direction with respect to the fixed base 4.

  Thus, in this embodiment, the stopper member is provided not only on the inner peripheral surface side of the rotary support 21 and the rotary body 22 but also on the outer peripheral surface side. As a result, when only the inner stopper members 30a, 31a, 30b, and 31b are provided, an excessive load is applied to the inner sides of the left and right divided rotating bodies 22a and 22b due to the inner stopper members hitting each other many times. However, there is a possibility that the divided rotating bodies 22a and 22b, which should have been assembled together for many years, may be separated, but the outer peripheral surfaces of the rotating support body 21 and the rotating body 22 as in this embodiment. By providing a stopper member also on the side, the problem that the divided rotating bodies 22a and 22b are separated can be solved. In particular, in this embodiment, as shown in FIGS. 11B and 11C, when the rotation of the rotating body 22 by the outer stopper members 35, 36, 37, 38 is restricted, the divided stopper members 35a, 35b and Since the rotation is regulated so that the members 36a and 36b are pressed against each other, the problem that the divided rotating bodies 22a and 22b integrally assembled are separated can be surely solved.

  Next, the structure of the vertical elevation angle rotation unit 10 will be described.

  As shown in FIGS. 6 and 10A, a pair of left and right armbands 28a and 28b extending forward from the respective divided rotating bodies 22a and 22b are formed on the upper part of the horizontal rotating unit 20, Between the armbands 28a and 28b, a rotation shaft 29 serving as a rotation center of the vertical elevation rotation unit is disposed horizontally. On the other hand, a flat rotation support rod 71 (see FIG. 2) is extended from the lower back of the camera case body 2 toward the rear, so that the rotation shaft 29 can be inserted into the rotation support rod 71. A rotation shaft hole (not shown) is formed. The rotation support rod 71 is inserted in the rotation shaft 29 through the rotation shaft 29, so that the rotation support rod 71 is supported by both arm rods 28a and 28b in the vertical direction (the arrow Y direction in FIGS. 1 and 2). It can be turned. A disc spring is interposed between the rotation support rod 71 and the arm rods 28a, 28b so that the vertical rotation position can be arbitrarily stopped.
