Description

The present invention relates to a protective cover structure.

Conventionally, a sensor device, a camera device, or the like has been installed on a wall or the like of a building (see, for example, Patent Document 1). When such a device or the like is installed on the surface of a building or the like, it is conceivable to further attach a structure (incidental object) including a cover member for covering the device or the like mainly for the purpose of protecting the device or the like.

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

FIG. 10 shows a plan view (10a) and a sectional view taken along line AA (10b) of the conventional structure. As shown in FIG. 10, the conventional structure 900 includes a protected object (incidental object such as a sensor device in this example) 200 installed on an installation object (in this example, a wall of a building) 100. It protects. The structure 900 has a protective cover 912 for covering the protected object 200 and a flange-shaped flange 914, and is attached to a cover member 910 capable of accommodating the protected object 200 inside and a hole formed in the installation object 100. An anchor 920 having a threaded groove inside, a screw 930 for fixing the flange 914, and a packing member 940 interposed between the flange 914 and the installation object 100 are provided. According to the conventional structure 900, it is possible to protect the device or the like which is the object to be protected 200 from the external environment such as wind and rain.

In addition, suitable examples of installation objects are mainly walls (parts exposed to space, mainly inner walls and outer walls) of various buildings (for example, roads, railways, bridges, water pipes, buildings). ) And pillars. However, as long as it makes sense to install the protective cover structure and the object to be protected, the object to be installed is not limited to the walls and pillars of the building. For example, the object to be installed may be a movable object such as a portable base for installing a camera device or a light emitting device.

The "protected object" in the present application means an object arranged inside a cover member constituting the protective cover structure. Further, suitable examples of the object to be protected are mainly a sensor device (a device provided with a temperature sensor, a strain sensor, a spirit level, etc., which detects some state or state change of the inspection target), a camera device (surveillance camera, etc., camera). (Devices equipped with), light emitting devices (devices equipped with light sources for lighting, light emission display, etc.), display devices (devices for displaying characters and figures, such as bulletin boards and information display boards). 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 used together with the above-mentioned 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 or the like and another device or the like.

The protective cover structure 1 according to the first embodiment protects the protected object 200 installed on the installation object 100. Although the installation object 100 is shown in a block shape in FIG. 1 and subsequent drawings, the area and thickness thereof are not particularly limited and may be larger or smaller than the illustrated area and thickness. The protected object 200 in the first embodiment is installed so as to be in contact with the installation object 100. As the installation method, known methods such as mounting, bonding, fitting, and welding can be exemplified. Further, when the object to be protected does not need to be in direct contact with the object to be installed, the object 200 to be protected 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 object 100 and the protection object 200 are not components of the protective cover structure 1. However, the protected object 200 may be included in the components of the protective cover structure 1.

However, the flange 14 may be formed over the entire outer circumference above the opening of the cup 12 or above it in a plan view. The flange 14 is a portion for interposing a self-adhesive silicone rubber adhesive member, which will be described later, with the installation object 100, and is referred to as a “part of the cover member”. The cover member 10 houses the object to be protected 200 inside (recessed portion). The cover member 10 is detachably attached to the self-adhesive silicone rubber adhesive member 20 on the installation object 100 by the second fixing member 40 and the first fixing member 30. The self-adhesive silicone rubber adhesive member 20 is a member that adheres to the first fixing member 30 and the installation object 100, and does not adhere to the cover member 10 itself.

The cover member 10 allows ultraviolet rays, visible light, infrared rays, or radio waves to pass through at least a part of the parts. At least a part of this is referred to here as a "passage". In this embodiment, the entire cover member 10 is a passing portion through which visible light and radio waves can pass. However, a passing portion may be provided in a part of the cover member 10. Further, in the present application, "passing ultraviolet rays, visible light, infrared rays or radio waves" means passing at least one kind of wavelengths of ultraviolet rays, visible light, infrared rays or electromagnetic waves corresponding to radio waves. Passing an electromagnetic wave over a wide wavelength range and passing two or more kinds of wavelengths are also included in "passing ultraviolet rays, visible light, infrared rays, or radio waves".

The wavelengths of ultraviolet rays, visible light, infrared rays, or radio waves that can pass through the cover member 10 differ depending on the type of the object to be protected 200. For example, when the object to be protected 200 is a sensor device (for example, one provided with an infrared sensor) for detecting the external state of the cover member 10, the passing portion of the cover member 10 is an ultraviolet ray having a wavelength used for detection. It is necessary to pass visible light, infrared rays or radio waves. Further, for example, when the object to be protected 200 is a camera device, a light emitting device, or a display device, the passing portion of the cover member 10 generally needs to be transparent or sufficiently transparent in order to allow visible light to pass through. There is. Further, when the protected object 200 performs data communication or the like by wireless communication using radio waves with the outside of the cover member 10, the passing portion of the cover member 10 needs to pass radio waves having a wavelength used for wireless communication. .. The above-mentioned passing portion is not essential for the cover member 10, and may not be provided.

The cup 12 may have a hemispherical shape (dome shape), a cylindrical shape, a cone shape, or a shape obtained by modifying these shapes. The cup 12 can be made of any material in consideration of the environment of the place where it is installed, the intensity, the wavelength of the electromagnetic wave to be passed (or blocked), the cost, and the like. Typical examples of the material constituting the cup 12 include metals (including metals and alloys having particularly high rust resistance), resins, rubbers, glass, ceramics, and wood. Further, the cup 12 may be made of a plurality of materials.
