  As shown in FIG. 1, the article of the present invention is an article 1 including a main body 2 and an openable / closable protective cover 3 for protecting a part thereof, such as a wireless amplifier used outdoors. The article includes an electrical device and an openable / closable protective cover for protecting the operation panel from environmental factors such as water, dust, sunlight, and malfunction caused by contact with humans.

  The protective cover 3 of the article of the present invention includes at least three positions including an open position as shown in FIG. 1, a closed position as shown in FIG. 2, and a midway position between these positions as shown in FIG. One stationary stable position can be taken and the stationary stable position between the open and closed positions can be increased as many as desired.

  As shown in FIG. 1, the protective cover 3 is connected to the main body via the connecting member 4, but when an excessive force is applied when the protective cover 3 is opened or closed (for example, the main body is lifted by holding the protective cover). In order to avoid damaging an article such as a protective cover, it is preferable that it can be attached and detached with a force less than the weight of the main body as shown in FIG. Further, the connection member 4 is housed in a recess 5 provided in the main body 2 and is detachably connected to the main body 2 in the recess 5 as shown in FIG. It is preferable.

  As can be seen from the exploded view with the outer cover removed in FIGS. 5A and 5B, the connecting member 4 comprises a rotating shaft 6 and a shaft holding member 7, and the shaft holding member 7 is an elastic member 8 (in the drawing). The surface along the axial direction of the rotary shaft 6 is pressed by a spring). The rotating shaft 6 is configured to receive both ends of the shaft fixedly by the protective cover 3, and when the rotating shaft 6 rotates around the shaft, the protective cover 3 rotates in conjunction with the opening / closing operation. The rotation angle range of the rotating shaft 6 is generally 45 ° or more and 270 ° or less, preferably 60 ° or more and 180 ° or less.

  In the present invention, while the rotary shaft 6 rotates, the surface along the axial direction of the rotary shaft 6 and the surface of the shaft holding member 7 that presses the rotary shaft 6 are engaged with each other so as to take a plurality of positions where they are stationary and stable. In these positions, a stationary stable position of the protective cover 3 is brought about. Therefore, if the number of stationary stable positions where these surfaces engage with each other is increased, the stationary stable position of the protective cover can be increased as well.

  Referring to FIG. 5C, a schematic cross-sectional view of an example of the connecting member 4 of the present invention is shown. In FIG. 5C, the axial cross section of the rotating shaft 6 is polygonal (octagonal in the figure), and the surface of the shaft holding member 7 that presses the surface along the axial direction of the rotating shaft 6 is It consists of a plane part that can contact with the sides of the polygon, and the plane parts engage with each other in a stable state in contact with the sides of the polygon, thereby taking a stationary stable position. In the embodiment of FIG. 5, if the rotating shaft 6 can make one rotation, the stationary stable positions can be taken as many as the number of octagonal sides (that is, eight places). The engagement pattern of the surface of the rotating shaft 6 and the surface of the shaft holding member 7 in FIG. 5C is merely an example, and other engagement patterns described below are also employed unless the effects of the present invention are impaired. Can do.

  6 (a) to 6 (d), another example of the connecting member 4 of the present invention is shown. In FIG. 6C, the axial cross section of the rotating shaft 6 is polygonal (octagonal in the figure), and the surface of the shaft holding member 7 that presses the surface along the axial direction of the rotating shaft 6 is It consists of a substantially V-shaped concave portion that can be brought into contact with the corners of the polygon. The concave portions engage with each other in a state of being in close contact with the corners of the polygon, thereby taking a stationary stable position. In this mode, in addition to the stationary stable position of FIG. 6C, as shown in FIG. 6D, the V-shaped concave portion equally receives adjacent corners of the polygon at the two sides constituting the V-shape. Even when engaged, the stationary stable position can be taken. In the embodiment of FIG. 6, if the rotating shaft 6 can make one rotation, the stationary stable position can be taken by the number twice as many as the side of the octagon (that is, 16 places).

  7A to 7D, still another example of the connecting member 4 of the present invention is shown. In FIG.7 (c), the axial cross section of the rotating shaft 6 is a polygon (an octagon in the figure), and the surface of the shaft holding member 7 that presses the surface along the axial direction of the rotating shaft 6 is It consists of a substantially V-shaped recess that can be brought into contact with the corners of the polygon and a flat portion that can be brought into contact with the sides of the polygon formed on both sides thereof. In this case, as shown in FIG. 7 (c), they are engaged with each other in a stable state in which the flat portions on both sides of the recess are in contact with the sides of the polygon, or as shown in FIG. Stability is stabilized by evenly receiving and engaging adjacent sides of the polygon at the two corners formed between the two sides constituting the V-shape of the recess and the flat portions on both sides continuously connected to them. You can take a position. In the embodiment of FIG. 7, if the rotary shaft 6 can make one rotation, the stationary stable position can be taken by the number twice as many as the side of the octagon (that is, 16 places).

  5-7, as an engagement pattern of the rotating shaft 6 and the shaft holding member 7, for example, when the axial cross section of the rotating shaft 6 is a polygon (preferably a hexagon or more) The surface of the shaft holding member 7 that presses the surface along the axial direction of the rotary shaft 6 is a flat surface that receives the polygonal side by contact, and the substantially V-shaped surface that receives the polygonal corner by contacting the valley. A concave portion, a substantially V-shaped concave portion composed of two sides that equally receive the two corners of the polygon, or a surface composed of a concave portion having two corners that equally receive the two sides of the polygon and a plane portion. It is done. In the first two modes, the surfaces are in contact with each other, and in the last two modes, the points are in contact with each other at two points. However, the stationary stability of the rotating shaft is higher in the contact between the surfaces than in the case of two-point contact. By adopting these engagement patterns, an appropriate clicking feeling is accompanied when the corners and sides of the polygon of the rotating shaft come into contact with the surface of the shaft holding member when the rotating shaft rotates. Further, when the inner angle of the polygon of the shaft holding member 7 is set to be an obtuse angle, preferably set to 120 ° or more, the polygon angle of the rotating shaft is less likely to be lost due to a large force even in many opening and closing operations. Therefore, it is preferable.

The coupling member 4 and the main body 2 are connected or disconnected by engaging or disengaging each other.

  As an example of the attaching / detaching mechanism of the connecting member 4 from the main body 2, a male part 9 provided on the connecting member 4 and a female part 10 provided in the recess 5 of the main body 2 are engaged with each other as shown in FIG. A joint portion that is coupled or disengaged and decoupled, as shown in FIG. 6 (c), a female portion 11 provided on the coupling member 4 and a male portion 12 provided in the recess 5 of the main body 2. 8 are formed by a leaf spring provided in the recess 5 of the main body 2 and a female portion 13 provided on the connecting member 4 as shown in FIG. Examples include those in which the male portions 14 are engaged and connected to each other, or are disengaged and disconnected. The force for attaching / detaching the connecting member 4 to / from the main body 2 can be set as appropriate depending on the material and size of the male and female parts, but the main body 2 does not follow even when the protective cover 3 is pulled with an excessive force. It is preferable that the force is released with a force less than the weight.
