When such a device or the like is installed on the surface of a building or the like, it is conceivable that a structure (attachment) including a cover member that covers the device or the like is further attached mainly for the purpose of protecting the device or the like.

  Regarding the attachment of a structure, it is known that a hole is first formed in a part of a wall of a building, then an anchor for fixing the structure is attached to the hole, and the structure is attached using the anchor. (For example, see Patent Document 2)

  FIG. 10 shows a plan view (10a) and a cross-sectional view along line AA (10b) of a conventional structure. As shown in FIG. 10, the conventional structure 900 includes a protection object (an accessory such as a sensor device in this example) 200 installed on an installation object (in this example, a building wall) 100. It is something to protect.

  The “installation object” in the present application refers to an object on which a protection object is installed. Moreover, the suitable example of an installation target object is mainly the wall (part exposed with respect to space. Mainly an inner wall and an outer wall) of various structures (for example, a road, a railway, a bridge, a water pipe, a building). ) And pillars. However, as long as it makes sense to install the protective cover structure and the protection target object, the installation target object is not limited to the wall or pillar of the building. For example, the installation object may be movable, such as a portable base for installing a camera device or a light emitting device.

  The “protection object” in the present application refers to an object disposed inside a cover member constituting the protective cover structure. Further, suitable examples of the object to be protected are mainly sensor devices (devices that include a temperature sensor, strain sensor, level, etc., and detect any state or state change of the inspection target), camera devices (monitoring cameras, cameras, etc.) Device), a light-emitting device (device including a light source for illumination, light-emitting display, and the like), and a display device (a device that displays characters and figures such as a bulletin board and a guidance display board). However, the object to be protected is not limited to the sensor device or the like as long as it can be arranged inside the cover member. The object to be protected may be one that is used together with the above device, such as a power supply device or an information transmission / reception device. Further, the object to be protected may be a combination of the above device and other devices.

  The protective cover structure 1 according to the first embodiment protects the protection target object 200 installed on the installation target object 100. In FIG. 1 and the subsequent drawings, the installation object 100 is shown in a block shape, but the area and thickness thereof are not particularly limited, and may be larger or smaller than the illustrated area and thickness. The protection target object 200 in the first embodiment is installed so as to be in contact with the installation target object 100. Examples of the installation method include known methods such as placement, adhesion, fitting, and welding. Moreover, when the protection target object does not need to be in direct contact with the installation target object, the protection target object 200 may be fixed to the cover member.

  As shown in FIG. 1, the protective cover structure 1 according to the first embodiment includes a cover member 10, a self-adhesive silicone rubber adhesive member 20, a first fixing member 30, and a second fixing member 40. The installation target object 100 and the protection target object 200 are not constituent elements of the protective cover structure 1. However, the protection object 200 may be included in the constituent elements of the protective cover structure 1.

  As shown in FIGS. 1 and 2, the cover member 10 includes a cup 12 having a rectangular top surface provided with a recess on the inside, and a flange 14. The flange 14 is an outwardly extending portion formed on at least a part of the outer periphery of the cover member 10.

Need to pass visible light, infrared or radio waves. For example, when the protection target 200 is a camera device, a light-emitting device, or a display instrument, generally, the passage portion of the cover member 10 needs to be transparent or sufficiently transparent to allow visible light to pass through. There is. Furthermore, when the object to be protected 200 performs data communication or the like with the outside of the cover member 10 by wireless communication using radio waves, the passage portion of the cover member 10 needs to pass radio waves having a wavelength used for wireless communication. . In addition, said passage part is not essential for the cover member 10, and does not need to be provided.

  In the first embodiment, the cup 12 has a substantially rectangular parallelepiped shape, but is not limited thereto. The cup 12 may have a hemispherical shape (dome shape), a cylindrical shape, a cone shape, or a shape obtained by deforming these shapes. The cup 12 can be made of any material in consideration of the environment of the installation location, the strength, the wavelength of the electromagnetic wave to be passed (or blocked), the cost, and the like. As a material which comprises the cup 12, a metal (especially including a metal and an alloy with especially high rust prevention property), resin, rubber | gum, glass, ceramics, and wood can be mentioned typically. The cup 12 may be composed of a plurality of materials.
