Description

  The present invention relates to a cover for an FPU that is used as rainwater or an awning covering a microwave external relay device (hereinafter referred to as an FPU device) for television relay.

  In a television camera, as shown in FIGS. 6A and 6B, the camera body is covered with an electromagnetic shielding cover to block electromagnetic waves from inside and outside the camera body. Referring to FIG. 1, the conventional shield cover 1 uses a sheet in which silver fibers are woven into a nylon fabric, and has a lens hood cover 2, a viewfinder cover 3, and a skirt as openings. Each of the lens hood cover 2 and the viewfinder cover 3 is provided with a string passage portion at the tip thereof, and the string can be squeezed through the string passage portion. The upper part of the shield cover 1 on the viewfinder unit 6 side has a space so that the viewfinder 6 of the camera 5 can move up and down. The bottom of the shield cover 1 has Velcro (registered trademark) 4, and the shield cover 1 can be held by the camera 5. The shield cover 1 has a ground portion 7 sewed in the shape of a strip with the same material. The ground portion 7 has an eyelet, and the shield cover 1 is connected to a moving tripod attached to the camera 5 by the eyelet portion. (See, for example, Patent Document 1).

  The above-mentioned electromagnetic shielding cover mainly aims to obtain a good image by protecting the TV camera from electromagnetic waves and preventing noise from entering the video signal. A waterproof sheet and a sheet having an awning effect are provided on the outer surface of the shield cover. However, when a sheet having an awning effect is provided on the electromagnetic wave shield cover, heat generated from the device is accumulated, which is not preferable, and heat from direct sunlight may be accumulated in the electromagnetic wave shield cover. When a plurality of protective sheets other than the electromagnetic wave shield are used in this way, there is a possibility that the device may be adversely affected due to heat dissipation of the device or heat accumulation due to direct sunlight. On the other hand, FPUs used for TV broadcasts are devices that are assumed to be used outdoors and have a structure that is strong against rainwater. The waterproofness may be water repellency against rainwater, and direct sunlight. What has been desired is one that can prevent heat accumulation due to heat and heat conduction to the device body.

  The present invention has been made in view of the above problems, and is a protective cover for an FPU device that has water repellency against rainwater and prevents heat accumulation due to direct sunlight and heat conduction to the device body. An object of the present invention is to provide a cover for an FPU that does not impair the heat dissipation of the device body.

The present invention achieves the above-mentioned problems, and the invention according to claim 1 is an FPU cover that covers an upper surface portion, both side surface portions, and a rear surface portion of an apparatus main body of an FPU device including an antenna on the front side and an operation unit on the rear side. Because
The FPU cover is made of a water-repellent processed resin sheet, and covers an upper surface sheet portion that covers the upper surface portion, and first and second side surface sheet portions that extend in both directions of the upper surface sheet portion and cover the both side surface portions. And a back cover portion that is provided behind the upper surface sheet portion and covers the rear surface portion, and a gap is formed inside the upper surface sheet portion between the upper surface portion of the device main body and the upper surface sheet portion. And a pair of annular tension members in the depth direction inside the upper surface sheet portion, and one tension member on each of the inner surfaces of the first and second side surface sheet portions. This is an FPU cover.

  According to a second aspect of the present invention, the first and second side surface sheet portions include a side surface protection portion that covers a rear main portion of the device body and a belt portion that covers a front end portion of the device body. A belt-like portion provided with a magic tape for holding the FPU cover on the device main body is provided at a lower end edge portion of the belt portion and the belt portion, and the back cover portion and the first and second side sheet portions The rear cover part is provided with a transparent window through which the operation part on the rear side of the device main body can be visually recognized, and the rear cover part is folded and placed on the upper sheet part. The FPU cover according to claim 1, further comprising an inclined surface portion that can be placed.

  According to the invention of claim 1, it is made of a water-repellent processed resin sheet, and an annular tension member is incorporated inside each of the upper surface sheet portion and the first and second side surface sheet portions of the FPU cover, The upper surface sheet portion and the both side surface sheet portions are stretched in a stretched state without being loosened or bent by the annular tension member, and the upper surface sheet portion is buffered by providing a buffer member on the inner surface of the upper surface sheet portion. A gap is formed between the upper surface portion and the upper surface sheet portion of the device body of the FPU device supported by the member, and heat due to direct sunlight is directly conducted to the device body by this space to the device body. There is an advantage that adverse effects can be reduced. In addition, outside air flows into the gap between the upper surface sheet portion and the upper surface portion of the apparatus main body, so that heat due to direct sunlight hardly accumulates, and the FPU device can be protected from direct sunlight. In addition, when the outside air flows into the gap, there is an advantage that the device main body is air-cooled with the outside air and the heat dissipation of the device main body itself is not impaired. Further, the FPU cover is a water-repellent resin sheet, and the top sheet portion and the first and second side sheet portions are stretched by a tension member, so that the accumulation of rainwater can be reduced. There is also an advantage that the FPU device can be protected by flipping rain water.

  According to the second aspect of the present invention, the first and second side sheet portions are composed of the side surface protection portion that covers the rear main portion of the device main body of the FPU device and the belt portion that covers the front end portion of the device main body. The side surface portion of the device main body is exposed from the notch portion between the belt portion and the belt portion, and the heat dissipation of the device itself is not impaired. In addition, a belt-like portion including a magic tape is provided at the lower edge portion of the side surface protection portion and the belt portion, and the FPU cover can be held on the apparatus main body by the belt-like portion. In addition, the operation part can be visually recognized through the transparent window provided in the back cover part, and when operating the FPU device, the fastener is opened and only the back cover part is separated from the first and second side sheets, and the operation on the back side of the device body is performed. It can be operated with the part exposed. It is also possible to operate through a space below the operation unit and the back cover unit. Further, the zipper can be opened and folded back upward so that the back cover portion is turned over, and the inclined surface portion of the back cover portion is brought into contact with the rear edge of the top sheet portion, so that the back cover portion can be placed on the top sheet portion. Therefore, there is an advantage that the operation unit is easy to operate. Further, when the FPU cover is not used, there is an advantage that the zipper can be opened and the back cover portion can be folded inward to be folded and stored compactly.
