Description

The present disclosure relates to hinges and cabinets with hinges.

For example, a cabinet for an electric/electronic device has a box for accommodating various electric/electronic devices such as a distribution board, and a door for covering an entrance of the box. A hinge connects the box and the door. As a result, the door is supported in the openable and closable state with respect to the box body.

When the electric/electronic device is installed inside the cabinet, the door sometimes interferes with the work even when the door is open. Therefore, the above work is generally performed with the door removed from the box.

The hinge described in Patent Document 1 below is inserted through both the hinge pin holder that is the portion that is attached to the door, the hinge receiver that is the portion that is attached to the box, and both the hinge pin holder and the hinge receiver. And a hinge pin that connects the two. The hinge pin holder described above holds the hinge pin at a position further outside the outer surface of the door. The hinge pin is provided with a hinge pin operation bar. The hinge pin operation bar projects from the outside to the inside of the door through an opening formed in the door. With the door open, the user can remove the door by sliding the hinge pin by operating the hinge pin operation bar from the inside of the door, releasing the engagement between the hinge pin holder and the hinge pin. ..

In such a configuration, since the hinge pin is arranged at a position further outside than the outer surface of the door, the door is widely opened so that the angle between the door and the box body is 180 degrees. can do. Further, since the operation for removing the door can be performed only from the inside of the door via the hinge pin operation bar, there is no security problem.

JP, 2010-267898, A

In the cabinet provided with the hinge described in Patent Document 1, as described above, the hinge pin operation bar projects to the inside of the door. When the door is closed, a part of the hinge pin operation bar projects from the opening toward the internal space of the cabinet. Therefore, when the door is closed, the tip of the hinge pin operation bar may interfere with the electric/electronic device or the wiring, and may damage them.

An object of the present disclosure is to provide a hinge that does not damage electric and electronic devices and wirings, and a cabinet including the hinge, even though the hinge pin can be operated from the inside of the door.

A hinge according to the present disclosure is a hinge that connects a door of a cabinet and a box body, and is a door side member attached to the door, a box side member attached to the box body, a door side member and a box side. A hinge pin that is inserted through both of the members. When one of the door-side member and the box-side member is the first member and the other is the second member, the hinge pin moves along the predetermined direction while being held by the first member, A first state in which a part of the hinge pin is inserted into the holding hole formed in the second member and a second state in which the entire hinge pin is disengaged from the holding hole are switched. With this hinge, the operation for switching between the first state and the second state can be performed from the inside of the door through the opening formed in the door, and the entire hinge pin is provided outside the door. It is characterized in that it is arranged at a position further outside the surface.

In the hinge having such a configuration, since the hinge pin is arranged outside the door, the door can be widely opened so that the angle formed by the door and the box body is 180 degrees. In addition, since the operation performed on the hinge pin when removing the door is performed from the inside of the door through the opening, it is possible to prevent the door from being removed by the operation from the outside. Further, since the entire hinge pin is arranged at a position further outside the outer surface of the door, a part of the hinge pin does not project to the inside of the cabinet through the opening. Therefore, unlike the hinge described in Patent Document 1, unlike the configuration in which the hinge pin operation bar protrudes inward through the opening, even when the door is closed, the hinge pin causes electrical and electronic equipment and wiring. Etc. will not be damaged.

According to the present disclosure, it is possible to provide a hinge that does not damage electric and electronic devices and wirings, and a cabinet including the hinge, even though the hinge pin can be operated from the inside of the door.

The present embodiment will be described below with reference to the accompanying drawings. In order to facilitate understanding of the description, the same reference numerals are given to the same constituent elements in each drawing as much as possible, and overlapping description will be omitted.

FIG. 1 is a perspective view showing the overall configuration of a cabinet 10 including a hinge 100 according to this embodiment. The cabinet 10 is for accommodating electric/electronic devices such as a distribution board and information communication device therein. As shown in FIG. 1, the cabinet 10 is formed as a rectangular box as a whole, and includes a box body 20, a door 30, and a hinge 100. FIG. 1 shows the cabinet 10 with the door 30 opened.

The box body 20 is a main part of the cabinet 10 and is a container in which a space for housing electric and electronic devices is formed inside. The box body 20 has a substantially rectangular parallelepiped shape that is long in the up-down direction. An opening 21 is formed on the front side surface of the box body 20. The opening 21 serves as an entrance/exit when the electric/electronic device is taken in and out from the inside of the box body 20.

The door 30 is a member that covers the opening 21 from the outside and that prevents a person from entering the inside of the cabinet 10 and the electric and electronic devices therein from being stolen. The door 30 is attached to a portion of the door 30 that is the edge of the opening 21 via a hinge 100 described below. Thereby, the door 30 is supported in a freely openable/closable state. Normally, the door 30 is locked in the closed state. The door 30 is in an open state as shown in FIG. 1 when performing maintenance of the electric and electronic devices inside.

The hinge 100 is for connecting the door 30 and the box body 20 while supporting the door 30 in the openable and closable state as described above. When the opening 21 is viewed from the front, the hinge 100 is provided at a position near the upper end of the right edge of the opening 21.

In the vicinity of the lower end portion of the edge of the opening 21, a pin (not shown) provided on the door 30 is inserted from an upper side into a hole (not shown) provided on the box body 20. Is supported so that it can be opened and closed. Instead of such an aspect, the hinges 100 are provided both near the upper end portion and near the lower end portion of the opening 21, and each hinge 100 supports the door 30 in an openable and closable state. It may be an aspect.

A specific configuration of the hinge 100 will be described. FIG. 2 is an enlarged view of the configuration of the hinge 100 and its vicinity when the door 30 is opened. In FIG. 3, the configuration of the hinge 100 and its vicinity is enlarged and shown in the state where the door 30 is closed. 2 and 3, the box body 20 is not shown in order to avoid complexity.

As shown in FIG. 3, the hinge 100 includes a box-side member 120 and a door-side member 110. The hinge 100 also includes a hinge pin 130 (not shown in FIGS. 2 and 3; see FIG. 4) that is inserted through both the box-side member 120 and the door-side member 110.

The box side member 120 is a part that is attached and fixed to the box 20. As shown in FIG. 2, the box-side member 120 has a fixed portion 121, an arm portion 123, and a holding portion 124.

The fixed portion 121 is a portion that is fastened and fixed to the box body 20. The fixed portion 121 has a substantially flat plate shape, and two through holes 122 are formed therein. The fixed portion 121 is fastened and fixed by inserting a bolt (not shown) into the through hole 122 while the main surface of the fixed portion 121 is in contact with the edge portion of the opening 21 of the box body 20.

The arm portion 123 is a portion that horizontally extends from the upper end portion of the fixed portion 121 in the direction opposite to the box body 20. The holding portion 124 is formed to extend downward from the tip of the arm portion 123.

FIG. 4 schematically shows the structure of the hinge 100. As shown in the figure, the holding portion 124 is formed with a holding hole 125 so as to recede in a concave shape from its lower end toward the upper side. The holding hole 125 is a bottomed hole whose upper end is closed. The holding hole 125 is a circular hole whose inner diameter is slightly larger than the outer diameter of the hinge pin 130. The holding hole 125 accommodates a part of the hinge pin 130 extending upward from the door-side member 110 therein. As a result, the door-side member 110 and the door 30 are rotatably supported around the central axis of the hinge pin 130.

The door-side member 110 is a part attached to and fixed to the door 30. As shown in FIGS. 3 and 4, the door-side member 110 is attached to the door 30 at a position directly below the holding portion 124. A gap is formed between the door member 110 and the holding portion 124.

In FIG. 2 and FIG. 3, the reference numeral “31” is a flat plate-shaped portion that occupies most of the door 30. Below, the said part is also called the "flat plate part 31." The surface of the flat plate portion 31 that is on the opposite side of the box body 20 when the door 30 is closed is also referred to as an “outer surface 32 ”below. Further, the outside of the outer surface 32 is described as “outside of the door 30”, and the inside of the outer surface 32, that is, the side of the box 20 is described as “inside of the door 30”. ..

FIG. 5 is a perspective view of the door-side member 110 removed from the door 30. In FIG. 5, the reference numeral 116 indicates the surface of the door-side member 110 that contacts the outer surface 32 of the door 30. Hereinafter, this surface is also referred to as “contact surface 116”.

Fastening holes 117 are formed on the contact surface 116 at two positions above and below the contact surface 116. Female threads are applied to the inner peripheral surface of the fastening hole 117. A through hole (not shown) is formed in the flat plate portion 31 at a position corresponding to the fastening hole 117. As shown in FIG. 2, the door-side member 110 is fastened and fixed to the flat plate portion 31 of the door 30 by the bolts 40 inserted into the through holes and the fastening holes 117.

A part of the contact surface 116 of the door-side member 110 recedes in a concave shape, thereby forming a space inside. The space is divided into upper and lower parts by a partition plate 113. The space above the partition plate 113 is also referred to as "space SP1" below. The space below the partition plate 113 is also referred to as "space SP2" below. The partition plate 113 is formed with a through hole 114 that vertically penetrates the partition plate 113.

Further, in the upper end surface 111 of the door-side member 110, a through hole 112 penetrating the upper end surface 111 in the vertical direction is formed at a position directly above the through hole 114. Each of the through hole 112 and the through hole 114 is a circular hole, and the inner diameter thereof is slightly larger than the outer diameter of the hinge pin 130.

The hinge pin 130 is a substantially cylindrical member made of metal. As shown in FIG. 5, the hinge pin 130 is held in a state of being inserted into the door-side member 110 so as to penetrate both the through hole 112 and the through hole 114. The vicinity of the upper end portion of the hinge pin 130 projects further upward than the upper end surface 111. As described above with reference to FIG. 4, the protruding portion of the hinge pin 130 is inserted through the holding portion 124 of the box-side member 120 from below and is housed inside the holding hole 125. To be done. In this way, a state in which a part of the hinge pin 130 is inserted into the holding hole 125 formed in the box-side member 120 corresponds to the “first state” in the present embodiment.

FIG. 6 is a diagram illustrating the door-side member 110 and the hinge pin 130 shown in FIG. 5 as viewed along a direction perpendicular to the contact surface 116. As shown in the figure, a spring 140 is arranged in the space SP1. The spring 140 is a so-called coil spring. The hinge pin 130 is arranged inside the spring 140. The lower end of the spring 140 is in contact with the upper surface of the partition plate 113. Further, the upper end of the spring 140 is in contact with the ring member 135 fixed to the hinge pin 130 from below. In the state of FIGS. 5 and 6, the spring 140 is shorter than its natural length. Therefore, the hinge pin 130 receives a force from the spring 140 via the ring member 135. Since the hinge pin 130 is biased upward by the spring 140, the state in which the upper end of the hinge pin 130 projects from the upper end surface 111 is maintained.

A recess 131 is formed in a portion of the hinge pin 130 near the lower end, specifically, in a portion of the hinge pin 130 arranged in the space SP2. The outer diameter of the hinge pin 130 in the recess 131 is smaller than the outer diameter of the hinge pin 130 in other portions. That is, in the recess 131, a part of the side surface of the hinge pin 130 recedes in a concave shape over the entire circumference,

As shown in FIG. 2, an opening 33 is formed in the flat plate portion 31 of the door 30. The opening 33 is formed so as to penetrate the flat plate portion 31 at a position corresponding to the space SP2. Therefore, when viewed from the inside of the door 30 as shown in FIG. 2, the space SP2 and the recess 131 of the hinge pin 130 are visible through the opening 33. In other words, the recess 131 is formed in a portion of the hinge pin 130 that faces the opening 33.

The user can operate the hinge pin 130 by gripping the recess 131 by inserting a finger into the opening 33 from the inside of the door 30. The recess 131 is a portion where a user performs an operation for switching between a first state and a second state, which will be described later. The concave portion 131 corresponds to the “operated portion” in this embodiment.

As is clear from the above description and FIG. 4 and the like, in the present embodiment, the hinge pin 130 as a whole is arranged at a position further outside the outer surface 32 of the door 30. Therefore, the door 30 can be widely opened so that the angle between the surface of the box body 20 in which the opening 21 is formed and the flat plate portion 31 of the door 30 is 180 degrees or more. Has become.

By the way, when the work of installing the electric/electronic device inside the cabinet 10 is performed, the door 30 may be a hindrance to the work even if the door 30 is widely opened as described above. .. For this reason, it is desirable that the above-mentioned work is performed with the door 30 removed from the box body 20.

The work performed by the user to remove the door 30 from the box 20 will be described. First, the user opens the door 30 as shown in FIG. Then, the user inserts a finger into the opening 33 from the inside of the door 30 and holds the recess 131 of the hinge pin 130. The user moves the hinge pin 130 downward by pulling down the recess 131 against the biasing force of the spring 140. As a result, the upper end position of the hinge pin 130 is lowered to a position close to the upper end surface 111 of the door side member 110. In FIG. 7, the door-side member 110 with the hinge pin 130 pulled down in this way is depicted from the same viewpoint as in FIG. 6.

In the state shown in FIG. 7, the hinge pin 130 is entirely removed from the holding hole 125 of the box-side member 120. That is, the hinge pin 130 is inserted only in the door side member 110, and is not inserted in the box side member 120. In this way, the state where the entire hinge pin 130 is disengaged from the holding hole 125 corresponds to the “second state” in this embodiment. In this state, the hinge 100 is separated into the door side member 110 and the box body side member 120. Therefore, the user can remove the door 30 from the box body 20. The above operation performed by the user holding the recess 131 can be said to be an operation of switching the hinge pin 130 from the first state to the second state.

The hinge pin 130 may have a cylindrical shape with the same diameter and the recess 131 may not be formed. However, it is preferable that the concave portion 131 is formed as the operated portion because the user can more easily perform the above operation.

When the door 30 is attached to the box body 20 again, the user may perform the operation in the reverse order of the above.

In the cabinet 10 according to the present embodiment, the hinge pin 130 is arranged at a position further outside the outer surface 32 of the door 30, so that the door 30 can be widely opened. In addition, since the hinge pin 130 can be operated only from the inside of the door 30, a situation where the door 30 is removed by an operation from the outside is prevented.

In order to more easily operate the hinge pin 130, a configuration may be considered in which the hinge pin 130 is provided with a rod-shaped operation bar and the operation bar is projected from the opening 33 to the inside of the door 30. However, in such a configuration, the operation bar projects inside the door 30. When the door 30 is closed, a part of the operation bar projects from the opening 33 toward the internal space of the cabinet 10. For this reason, when the door 30 is closed, the tip of the operation bar may interfere with electric and electronic devices and wiring, and may damage them.

On the other hand, in the present embodiment, the entire hinge pin 130 is arranged at a position further outside the outer surface 32 of the door 30. In such a configuration, part of the hinge pin 130 does not project inside the cabinet 10. Therefore, even when the door 30 is closed, the hinge pin 130 does not damage the electric/electronic device, the wiring, or the like.

As described above, the hinge 100 according to the present embodiment has the door-side member 110 attached to the door 30, the box-side member 120 attached to the box 20, the door-side member 110, and the box-side member 120. And a hinge pin 130 that is inserted into both of the above. While the hinge pin 130 is held by the door-side member 110, the hinge pin 130 moves along a predetermined direction (vertical direction in this embodiment), so that part of the hinge pin 130 is formed on the box-side member 120. The first state in which the hinge pin 130 is inserted into the holding hole 125 and the second state in which the entire hinge pin 130 is disengaged from the holding hole 125 are switched. In the hinge 100, the operation for switching between the first state and the second state can be performed from the inside of the door 30 through the opening 33 formed in the door 30. The hinge pin 130 is arranged at a position further outside than the outer surface 32 of the door 30 as a whole. As a result, it is possible to prevent the hinge pin 130 from damaging the electric/electronic device or the like, even though the hinge pin 130 is operated from the inside of the door 30.

In the present embodiment, the door-side member 110 corresponds to the “first member” that holds the hinge pin 130 in a vertically movable state, and the box-side member 120 has the holding hole 125. It corresponds to the formed "second member". On the contrary to such a mode, the box-side member 120 may correspond to the “second member” and the door-side member 110 may correspond to the “first member”. That is, the hinge pin 130 slides up and down while being held by the box-side member 120, so that a part of the hinge pin 130 is inserted into the holding hole provided in the door-side member 110 in the first state. And the second state in which the entire hinge pin 130 is disengaged from the holding hole may be switched. Even in such a mode, the same effect as that described so far can be obtained.

The configuration of the hinge 100 is not limited to the mode as described above, and various changes can be added. FIG. 8 schematically shows the configuration of the hinge pin 130 included in the hinge 100 according to the modified example of the present embodiment. In this modified example, the outer diameter of the portion of the hinge pin 130 below the recess 131 is larger than the outer diameter above the recess 131, thereby forming the large diameter portion 132. .. When the user holds the recess 131 and performs the operation of switching between the first state and the second state, the large diameter portion 132 is related to the user's finger, so that the above operation can be performed more easily. Has become. In this modification, the concave portion 131 and the large diameter portion 132 correspond to the “operated portion”. As described above, in the operated portion, a part of the side surface of the hinge pin 130 may be projected outward. However, also in this modified example, it is preferable that the hinge pin 130 as a whole, including the large diameter portion 132, is arranged at a position further outside the outer surface 32 of the door 30.

Another modification will be described with reference to FIG. In this modification, the hinge pin 130 has a recess 133 instead of the recess 131. Unlike the recess 131, the recess 133 is not formed over the entire circumference of the hinge pin 130, but is formed only on the surface of the hinge pin 130 on the door 30 side. In this modification, the concave portion 133 corresponds to the “operated portion”. The portion below the recess 133 may be configured to project toward the door 30 as indicated by the dotted line D1 in FIG. However, even in this case, it is preferable that the hinge pin 130 is arranged at a position where the whole including the protruding portion of the dotted line D1 is further outside the outer surface 32 of the door 30.

The present embodiment has been described above with reference to specific examples. However, the present disclosure is not limited to these specific examples. Those obtained by those skilled in the art who appropriately change the design are also included in the scope of the present disclosure as long as they have the features of the present disclosure. The elements provided in each of the specific examples described above and the arrangement, conditions, shapes, and the like of the elements are not limited to those illustrated, but can be appropriately changed. The respective elements included in the above-described specific examples can be appropriately combined as long as there is no technical contradiction.
