Description

  The present invention relates to a housing of a device or apparatus. More specifically, the present invention relates to a housing having a lid that is supported so as to be rotatable about an axis along a part of the periphery of the opening of the main body.

  In general, in an apparatus, particularly an electric device, it is necessary to open a part of the housing and look inside the interior in order to inspect the interior, replace parts, or change settings during the operation period. In order to hold the exterior member of the opening portion during such maintenance, a housing having a door that is rotatably supported by the main body may be used.

  In a housing provided with a door, depending on the installation location of the device, there is an obstacle in opening and closing the door, and the door may not be completely opened. In preparation for such a case, it is convenient to be able to open and close the door to the left and right.

  For example, Patent Document 1 describes a configuration of a hinge that can open and close a switchboard door on either the left or right side. In the technique of Patent Document 1, hinges are provided on the left and right of the door of the switchboard, and as a configuration of the hinge, a cylindrical material is fixed to the door and a pair of steel balls is provided in the cylindrical material via a spring, while a housing Is formed with a concave portion corresponding to the length of the cylindrical material, and a spherical concave portion into which a steel ball is inserted is formed at both ends of the concave portion. Make it free.

  Patent Document 2 describes the technology of a storage box having a structure that allows the door opening direction relative to the box body to be changed, and allows the position of a specific side portion of the door to be changed vertically and horizontally. ing. In the technique of Patent Document 2, the storage box is composed of a box body and a door attached to the opening side end of the box body. The upper and lower mounting holes on the left and right side walls of the box main body are formed so that joint members can be mounted respectively. Two pairs of bearings opposite to each other are formed on the back surfaces of the second side portion and the third side portion adjacent to each other. Then, by changing the attachment position of the joint member and rotating the door 90 degrees in the circumferential direction and connecting the door, the door opening direction can be changed, and the one side portion where the grip piece is formed The position can be changed to the adjacent side part.

  In the technique described in Patent Document 3, the base end of the first arm is hinged to the left and right sides of the outer wall of the cargo box, and the tip of the arm is hinged to the left and right sides of the open / close lid, respectively. The base end of the second arm is connected to the left and right side of the outer wall, and the tip of the arm is hinged to the left and right side of the opening / closing lid. When the opening / closing lid is opened to the left and right sides, When the second arm is left behind, the opening / closing lid rotates together with the first arm, and when the opening / closing lid is opened to the left and right sides, the opening / closing lid rotates together with the second arm while leaving the first arm on the outer wall. Move.

  A related technique that can open and close the door to both the left and right sides is to devise the hinge structure and change the position of the shaft that rotatably supports the door. The door structure that can be opened and closed by the related technology is configured such that a spring and a steel ball are used as a hinge to serve as a hinge and a catch (Patent Document 1), and the arm or bearing of the hinge and the shaft can be divided. . Therefore, the hinge has a complicated structure.

  The present invention is particularly assumed to be applied to a housing such as a flashlight device. For example, a flashlight is provided in a very high structure such as a steel tower, a chimney, a suspension bridge pier, or a light guide of a runway, and always emits a flash to inform an aircraft or the like of its position. Since it always operates, maintenance such as exchanging the tube regularly is necessary. Since maintenance is a work at a high place, it is necessary to have a door structure in which the lid is rotatably supported.

  In the case of a device where the installation location is limited, it is necessary to be able to change the opening and closing direction of the door in accordance with the surrounding conditions of installation. However, in the case of a flashlight device, it is not necessary to change the door opening / closing direction after the door opening / closing direction is determined at the time of installation. Moreover, since it is installed outdoors, the door needs a rainproof structure and the hinge is required to be durable. The door structure that can be opened / closed to the left and right of the related technology may change the opening / closing direction of the door each time it is opened / closed. However, the flashlight device does not need that much, but rather it is important that the structure be robust and rainproof. .

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a housing that can change the opening and closing direction of a door with a simple structure.

The housing according to the first aspect of the present invention is:
A housing having an opening, and an exterior member that is supported rotatably about an axis along a part of the periphery of the opening and capable of opening and closing the opening,
The main body is detachable with a hinge that rotatably supports the exterior member, and an attachment portion that can fix the hinge corresponds to each of at least two different rotation center axes of the exterior member. Prepared ,
The exterior member includes a fixing portion that can attach and detach the hinge and can fix the hinge corresponding to each of the at least two different central axes of rotation of the exterior member.
It is characterized by that.

  The exterior member may include a hinge that rotatably supports the exterior member in correspondence with each of the at least two different rotation center axes of the exterior member.

Alternatively, the exterior member has a rotationally symmetric shape except for the fixed portion of the hinge,
The position of the attachment portion of the main body may be configured to be rotationally symmetric with respect to a line parallel to the rotationally symmetric axis of the exterior member at a position where the exterior member closes the opening.

  In particular, the case may be a case of a flashlight device.

  According to the housing of the present invention, in a housing comprising a main body having an opening, and an exterior member that is supported rotatably about an axis along a part of the periphery of the opening and that can open and close the opening, The opening / closing direction of the exterior member can be changed with a simple structure.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and description thereof will not be repeated.

Example 1
FIG. 1 is an elevation view illustrating a configuration example of a housing according to the first embodiment of the present invention. The housing 10 includes a main body 1, a door 2, a hinge 3, and a mounting portion 5. The main body 1 is a box that houses equipment, and has an opening 4. The door 2 is an exterior member that opens and closes the opening 4 and is rotatably supported by the hinge 3.

  The attachment portion 5 is a pedestal that fixes the hinge 3 with a fastening member such as a screw. The attachment part 5 can attach and detach the hinge 3. The attachment portion 5 is formed on the outer wall of the casing at the periphery of the opening 4 of the main body 1 so as to face both sides of the opening 4. The attachment portion 5 may be a member attached by welding or the like, or may be formed integrally with the main body 1 without attaching a member.

  FIG. 2 is a side view showing attachment of the hinge 3. A fixing portion 6 for fixing the hinge 3 is formed on the door 2 so as to correspond to an axis that rotatably supports the door 2 (see FIG. 1). The fixing portion 6 is, for example, a flat surface so as to fit the hinge 3, and a screw hole 8 for fastening the hinge 3 is formed. Similarly, a screw hole 8 is formed in the attachment portion 5 of the main body 1. The hinge 3 is fastened with the screw 7 and the screw hole 8 and is attached across the attachment portion 5 and the fixing portion 6. The door 2 is supported so as to be rotatable about the rotation axis of the hinge 3.

  The method of fixing the hinge 3 to the mounting portion 5 and the fixing portion 6 is not limited to the screw 7, and a method using a detachable bush or a pinching mechanism using an appropriate elastic body or a lever may be used. In the example of FIG. 2, two hinges 3 are used for one rotatable support shaft. The number of hinges 3 with respect to one rotatable support shaft may be one or more. The structure of the detachable hinge 3 may be based on a known technique.

  As shown in FIG. 1, when the hinge 3 is fixed to the left as viewed in FIG. 1, the door 2 opens in the left direction indicated by the arrow L (counterclockwise in FIG. 1). The hinge 3 fixed to the left side can be removed, and the hinge 3 can be attached to the right mounting portion 5 and the fixed portion 6 as viewed in FIG. When the hinge 3 is fixed to the right side, the door 2 opens in the right direction indicated by the arrow R (clockwise in FIG. 1).

  An attachment portion 5 and a fixing portion 6 are formed corresponding to a shaft on which the door 2 is pivotably supported, and the hinge 3 is attached to the attachment portion 5 and the fixing portion 6 corresponding to any one of the support shafts. The opening / closing direction of the door 2 can be changed.

  In the example of FIG. 1, the attachment portion 5 and the fixing portion 6 are formed to face both sides of the opening portion 4, but the attachment portion 5 and the fixing portion 6 can be provided at other positions. The attachment portion 5 and the fixing portion 6 are formed corresponding to the support shaft of the door 2 along a part of the periphery of the opening 4. For example, when the mounting portion 5 and the fixing portion 6 are formed so that the support shaft of the door 2 is located at the upper or lower position as well as the left and right toward the opening 4, the door 2 is opened upward or downward. Can be.

  Note that the door 2 may have any shape, for example, an arbitrary polygon or a circle as long as the condition that it can be opened and closed about two or more different axes along a part of the periphery of the opening 4 is satisfied. It doesn't matter.

  As described above, according to the housing of the present invention, the exterior member that is supported so as to be rotatable about an axis along a part of the periphery of the main body having the opening and the opening and that can open and close the opening. In the case including the above, the direction in which the exterior member opens and closes can be changed with a simple structure. In particular, the door opening / closing direction can be changed while the hinge 3 is installed outside the housing. As a result, it can be applied to a housing having a waterproof structure (including rainproof or drip-proof structure) such as a flashlight device.

(Example 2)
FIG. 3 is an elevation view showing a configuration example of the housing 10 according to the second embodiment of the present invention. In the second embodiment, the hinges 3 are already fixed to the door 2 at a plurality of locations corresponding to different pivotable support shafts of the door 2. In the example of FIG. 3, hinges 3 are provided on the left and right sides of the housing 10 toward FIG. 3. The attachment part 5 can attach and detach the hinge 3 as in the first embodiment.

  The hinge 3 at a position corresponding to one of the pivotally supported shafts of the door 2 is fixed to the corresponding mounting portion 5 and the other hinge 3 is removed from the mounting portion 5 to be fixed to the mounting portion 5. The door 2 is rotatably supported around the rotation axis of the hinge. The hinge 3 may be structured to be fixed to the door 2 as in the first embodiment. For example, one of the wings of the hinge 3 may be formed integrally with the door 2.

  FIG. 4 shows the open / closed state of the door 2 for the housing 10 of FIG. When the hinge 3 is fixed to the left mounting portion 5 as viewed in FIG. 3, the door 2 opens counterclockwise as shown in FIG. On the other hand, when the hinge 3 is fixed to the right mounting portion 5 as viewed in FIG. 3, the door 2 opens clockwise as shown in FIG. 4 (b). In this way, only the hinge 3 at a location corresponding to one of the pivotally supported shafts of the door 2 is fixed to the mounting portion 5, and the other hinges 3 remain fixed to the door 2, and the door 2. Opens and closes.

  In the present Example 2, the attaching part 5 is formed corresponding to the axis | shaft which supports the door 2 so that rotation is possible, and the hinge 3 is provided corresponding to them. By fixing the hinge 3 corresponding to the mounting portion 5 corresponding to any one of the support shafts to the mounting portion 5 and not fixing the other hinge 3, the opening / closing direction of the door 2 can be changed with respect to the main body 1. In the second embodiment, when the pivotable support shaft of the door 2 is changed, it is not necessary to remove the hinge 3 from the door 2 and attach it to another location again.

  Also in the second embodiment, for example, if the mounting portion 5 and the hinge 3 are provided so that the support shaft of the door 2 is in the upper or lower position toward the opening 4 as well as the left and right, the door 2 is It can be opened up or down. In addition, the door 2 may have any shape, for example, an arbitrary polygon or a circle as long as the condition that it can be opened and closed around two or more different axes along a part of the periphery of the opening 4 is satisfied. It doesn't matter.

(Example 3)
FIG. 5 is a diagram illustrating a configuration example of a housing according to the third embodiment of the present invention, and is a diagram illustrating a change in the opening / closing direction of the door 2. In the third embodiment, the door 2 and the hinge 3 are integrated, and the direction of opening and closing is changed by changing the direction and attaching the hinge 2 to the main body 1. In Example 3, the shape of the door 2 is rotationally symmetric except for the fixed portion of the hinge 3.

  In the example of FIG. 5, the housing 10 has attachment portions 5 formed on the left and right sides of the main body 1 toward FIG. 5. The method for fixing the hinge 3 to the attachment portion 5 is the same as that in the first embodiment. The hinge 3 is fixed to the door 2. The wings of the hinge 3 may be formed integrally with the door 2. In FIG. 5A, the hinge 3 is fixed to the left mounting portion 5. Then, the door 2 opens counterclockwise toward FIG.

  The hinge 3 is removed from the mounting portion 5, the door 2 and the hinge 3 are kept integral, and the opening 3 is rotated 180 degrees around the normal line (line in the drawing), and the hinge 3 is attached to the right side as viewed in FIG. It can be fixed to the part 5. In that case, as shown in FIG.5 (b), the door 2 opens clockwise toward FIG.

  FIG. 6 is a plan view for explaining the change in the opening / closing direction of the door 2. The door 2 is rotationally symmetric except for the fixed portion of the hinge 3. The attachment portion 5 is formed at a rotationally symmetric position with respect to the rotationally symmetric axis of the door 2 at the position where the door 2 is closed. While the door 2 and the hinge 3 remain integrated, the hinge 3 is rotated to a rotationally symmetric position (indicated by a two-dot chain line in FIG. 6) about the rotational symmetry axis, and the hinge 3 is fixed to the corresponding attachment portion 5 of the main body 1. As a result, as shown in FIG. 5, the opening / closing direction of the door 2 can be changed.

  FIG. 7 shows an example of the shape of the rotationally symmetric door 2. In the third embodiment, the shape of the door 2 is not limited to FIGS. 6 and 7 as long as the shape of the door 2 is rotationally symmetric except for the hinge 3 portion. FIG. 7A shows a case where the door 2 is a substantially equilateral triangle, FIG. 7B shows a case of a regular hexagon, and FIG. 7C shows a case of a circle.

  In the example of FIGS. 7B and 7C, one hinge 3 is represented with respect to one pivotable shaft of the door 2. As shown in FIG. 7, the position of the hinge 3 may correspond to the number of rotational symmetry of the door 2. For example, there are 2 ways for parallelograms (including rectangles and rhombuses), 3 for regular triangles, 3 for axes, 4 for squares for 4 times, and 6 for regular hexagons. In FIGS. 7A and 7B, all rotationally symmetric positions are shown, but the attachment portion 5 may not be provided corresponding to all rotationally symmetric positions. As shown in FIG.7 (c), when the door 2 is circular, the attachment part 5 is provided in the arbitrary locations on the circumference | surroundings, and the axis | shaft which can rotate the door 2 can be changed.

  FIG. 8 shows a different example of the third embodiment. The example of FIG. 8 is a case where the door 2 is rotationally symmetric about a line parallel to the opening surface at the position where the door 2 is closed. In FIG. 8, in order to show the direction of the door 2, the one side of the cross section is hatched.

  In FIG. 8A, the hinge 3 is fixed to the left mounting portion 5. Then, the door 2 opens counterclockwise toward FIG. 8, the hinge 3 fixed to the left mounting portion 5 is removed, the door 2 is rotated 180 degrees around a line parallel to the opening surface (a line perpendicular to the paper surface), and the hinge 3 is moved to the right side. It can be fixed to the mounting portion 5. As a result, as shown in FIG. 8B, the door 2 opens clockwise toward FIG.

  The hinge 3 is fixed to the door 2. The wings of the hinge 3 may be formed integrally with the door 2. In FIG. 8, the door 2 is a wing of the hinge 3. In the example of FIG. 8, the attachment portion 5 is in a mirror-symmetrical position with respect to a plane including the center line of the housing. In other words, the door 2 is turned upside down and faces the opening surface. For this reason, the hinge 3 needs to be reversible. At least the left and right attachment portions 5 are formed so as to fit the front and back of the hinge 3, respectively.

  The door 2 may not be planar as long as it is rotationally symmetric. For example, the cross section may be a crank shape. In that case, the opening surface is stepped when viewed in the direction of FIG. In general, including the case, the position of the mounting portion 5 is rotationally symmetric with respect to a line parallel to the rotational symmetry axis of the door 2 with the door 2 closed. For example, in consideration of the position of the screw hole 8 of the mounting portion 5 and the front and back of the hinge 3, it is not strictly rotationally symmetric. Strictly speaking, even when the surfaces of the left and right attachment portions 5 are not parallel, it cannot be said to be rotationally symmetric. However, in the present invention, the positions including rotational symmetry are included.

  As described above, according to the housing of the present invention, the exterior member that is supported so as to be rotatable about an axis along a part of the periphery of the main body having the opening and the opening and that can open and close the opening. In the case including the above, the direction in which the exterior member opens and closes can be changed with a simple structure. In particular, the door opening / closing direction can be changed while the hinge 3 is installed outside the housing. As a result, it can be applied to a housing having a waterproof structure (including rainproof or drip-proof structure) such as a flashlight device.

  Although the embodiments of the present invention have been described, the present invention is not limited to the above-described embodiments, and various embodiments are possible within the scope of the present invention.
