DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tilt structure for a camera-equipped entrance device, and more particularly to a tilt structure for a camera-equipped entrance device that can set a vertical angle of a camera from the front of the entrance device.

[0002]

2. Description of the Related Art As shown in FIG. 3, a conventional tilt structure for a camera-equipped front door unit has a camera 10 for capturing a visitor and a fulcrum 3 for supporting the camera 2 in a housing 10. 1
It has a support 4 fixed to 0 and a substrate 5 on which the camera 2 is mounted, and a lever fitting portion 51 is provided on the back surface of the substrate 5.

[0003] A lever 6 for rotating the camera 2 mounted on the substrate 5 in the tilt direction is provided on a back surface 12 of the housing 10.
A lever movement hole 19 is formed so that the housing 8 can be moved, and an operation unit 69 for operating the lever 68 is located between the back surface 12 of the housing 10 and the wall surface W on which the housing 10 is mounted. When changing the vertical angle of the camera 2 that captures a visitor (tilt adjustment), when turning the camera 2 in the A direction, slide the operation unit 69 in the A ′ direction and turn the camera 2 in the B direction. At this time, the operation unit 69 is slid in the direction B ′. Since the fulcrum 3 of the camera 2 is supported by the support 4 fixed to the housing 10, the fulcrum 3 of the camera 2 mounted on the substrate 5 is centered by the slide of the lever 68 linked to the slide of the operation unit 69. Turns.

[0004]

In the above-mentioned conventional tilt structure for a camera-equipped front door, the operation unit 69 is provided on the rear surface 12 of the housing.
, There is a drawback that work cannot be performed unless the front door with camera is removed from the wall W. Further, the operation part 69 of the lever 68 can be adjusted in two or three steps, but cannot be finely adjusted steplessly.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and has a camera-equipped entrance door which can be operated from the front side of the equipment housing and can be finely adjusted steplessly after the equipment is installed. It is intended to provide a tilt structure for a machine.

[0006]

According to the present invention, there is provided a tilt structure for a camera-equipped entrance device, wherein a camera for imaging a visitor and a support fixed to the housing for supporting a fulcrum of the camera are provided in the housing. A substrate mounted with a camera, a gripper for gripping the substrate, and holding and moving the gripper, a shaft having a head disposed on the surface of the housing, and preventing rotation of the gripper. A pair of sandwiching ribs provided on the housing, the gripping portion has a gripping groove having an inclination angle allowing rotation of the substrate, and an outer periphery of a base of the gripping portion has a square shape, a gripping portion, and a shaft. Screws screwed to each other are provided between the columns, and the head of the shaft rotates the shaft.

When the head of the shaft provided on the surface of the housing is rotated, the gripping portion relatively moves in the longitudinal direction of the shaft,
The gripped substrate is tilted along the tilt of the gripping groove, and the camera mounted on the substrate is tilt-adjusted. Further, in the tilt structure for a front door apparatus with a camera according to the present invention, a spring is stretched between the holding portion and the housing, and the movement of the holding portion is stably performed by the tension of the spring.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a tilt structure for a front door unit with a camera according to the present invention will be described below in detail with reference to the drawings. As shown in FIGS. 1A and 1B, a tilt structure for a front door apparatus with a camera according to the present invention supports a camera 2 for imaging a visitor and a fulcrum 3 of the camera 2 in a housing 1. Therefore, the support 4 fixed to the housing, the substrate 5 on which the camera 2 is mounted, the gripper 6 for gripping the substrate 5, the gripper 6 is held and moved, and the head 71 is moved to the surface of the housing 1. 11 is provided with a pair of clamping ribs 8 provided on the housing 1 for preventing rotation of the gripper 6. The gripper 6 allows the substrate 5 to turn. The grip 60 has a grip groove 61 having an inclination angle θ, the outer periphery of the base 60 of the grip 6 has a rectangular shape, and screws 62 and 72 screwed to each other are provided between the grip 6 and the shaft 7. A driver groove 73 for rotating the shaft 7 using a driver D is formed in the head 71 of the holder 1. Spring 9 is stretched between. The inclination angle θ of the holding groove 61 is preferably a value obtained by adding about 3 ° to the angle at which the substrate 5 is inclined.

[0009] The side of the rear surface 12 of the shaft 7 is
The head 7 of the shaft 7 is inserted into the shaft
On one side, the enlarged portion 74 having a large diameter and the housing surface 1
An O-ring is inserted between them. When the driver D is brought into contact with the driver groove 73 of the shaft 7 from the surface 11 of the housing 1 and rotated, the shaft 7 rotates, but as shown in FIG. It cannot be rotated because it is sandwiched between the attachment ribs 8, 8, and the screw 62 of the gripping portion 6 and the screw 72 between the shaft posts 7 are screwed together, so that the rotation of the shaft post 7 can be performed steplessly and relatively. The grip 6 moves in the longitudinal direction of the shaft 7.

When the grip 6 moves in the X direction, the grip 6
The substrate 5 held by the camera 2 is inclined along the inclination of the holding groove 61, and the fulcrum 3 of the camera 2 is supported by the support 4 fixed to the housing 10.
, The substrate 5 tilts around the fulcrum 3 of the camera 2, and the camera 2 mounted on the substrate 5 turns steplessly in the direction A. Similarly, when the gripper 6 moves in the Y direction, the camera 2 mounted on the substrate 5 turns in the B direction.

A spring 9 is stretched between the grip 6 and the back surface 12 of the housing 1.
The movement of the grip portion 6 is performed stably without rattling. Shaft column 7
Since the O-ring 75 is inserted between the enlarged portion 74 and the housing surface 11, the infiltration of rainwater from the housing surface 11 is prevented, and at the same time, the effect of preventing the shaft column 7 from slipping is obtained.

[0012]

As is clear from the above description, according to the tilt structure for a camera-equipped front door unit of the present invention, a camera for imaging a visitor and a housing for supporting a fulcrum of the camera are provided in the housing. A support fixed to the camera, a substrate on which a camera is mounted, a gripper for gripping the substrate, a shaft column having a head held and moved to hold the gripper, and a head disposed on the surface of the housing; and a gripper. A pair of sandwiching ribs provided on the housing to prevent the rotation of the holding member, the holding portion has a holding groove having an inclination angle that allows the substrate to turn, and the outer periphery of the base of the holding portion is square. Without
Screws screwed to each other are provided between the grip portion and the shaft post, and the shaft post is rotated by the head of the shaft post, so that the head of the shaft post disposed on the surface of the housing even after installation of the device. When rotated, the gripping portion moves relatively in the longitudinal direction of the shaft column in a stepless manner according to the rotation of the shaft column, and the gripped substrate tilts along the tilt of the grip groove, and the camera mounted on the substrate. Is adjusted for tilt.

Further, since the spring is stretched between the grip portion and the housing, the grip portion is stably moved by the tension of the spring.
