An embodiment of the present invention will be described below with reference to FIGS. 1A is a rear view of the electronic device 1 of the present embodiment, and FIG. 1B is a bottom view of the electronic device 1 of FIG. A one-dot chain line in FIG. 1A indicates the center position (center line) of the length in the width direction. FIG. 2 is a perspective view of the electronic device 1. In the following description, the state of the electronic device 1 in FIG. In the present embodiment, the electronic device 1 displays a state of a control panel or a device controlled by the control panel, and includes a display unit (front surface of a display device such as a liquid crystal display) having an operation unit that sends instructions to the control device in the control panel. It is assumed that the touch panel is attached to the device.

  As shown in FIG. 1, the electronic device 1 includes a housing 3. The housing 3 is made of, for example, resin. In the housing 3, various devices (for example, an LCD, a substrate, a memory, a CPU, an external communication connector, and the like) constituting the electronic device 1 are stored.

  The housing 3 includes a box-shaped front member 3a whose front side is open and a box-shaped rear member 3b whose front is open. Further, a flange portion 2 formed integrally with the front member 3a is provided at the front edge of the front member 3a. The flange portion 2 has a shape that protrudes outward from the opening on the front side of the front member 3a. The flange portion 2 is formed in a frame shape, and a display panel such as a liquid crystal panel is fitted inside the frame. By fitting the display panel, the opening of the front member 3a is closed.

  The rear member 3b is a box-shaped member having an opening formed on the front side. The edge of the opening of the rear member 3b is in contact with the back surface of the front member 3a, and is fixed to the front member 3a with a plurality of screws, for example. In the electronic device 1 of the present embodiment, as shown in FIG. 1A, the rear member 3b is a left and right left region (the other region) with respect to the center of the length in the width direction of the electronic device 1. Present in the first region. Therefore, in the present embodiment, the center of gravity of the electronic device 1 in the width direction is located to the left of the center (center) of the length in the width direction, and exists in the first region. Here, the center of gravity is not limited to being present in the first region, and, as will be described later, if the center of gravity and the position of the movable hook are shifted in the lateral width direction of the electronic device 1, It may exist or may exist in the second region.

  In addition, in this embodiment, although the front side member 3a and the rear side member 3b are screwed, it is not limited to this. For example, the engagement claw formed on one side may be engaged with the engagement recess formed on the other side and fixed. Or you may fix using the well-known method which can fix the front side member 3a and the rear side member 3b firmly. In addition, although not shown in the figure, an input / output connector arrangement portion in which a connector for connecting a cable for connection with an external device or a power cable connected to an external power source is connected to the back surface of the front member 3a. The power supply connection part etc. which are provided are provided, but these are omitted.

  The electronic device 1 further includes a movable hook 4 on the upper part of the front member 3a of the housing 3 and ribs 5a and 5b on the lower surface. Since the electronic device 1 is temporarily temporarily fixed to the vertical wall Vw by the movable hook 4 and the ribs 5a and 5b, as will be described later, the movable hook 4 and the ribs 5a and 5b are collectively combined with temporary fixing means. Called. Details of the movable hook 4 and the ribs 5a and 5b will be described below. The two ribs 5a and 5b will be described as ribs 5 when they are not distinguished from each other.

  FIG. 3 is an enlarged view of the movable hook 4 and the casing 3 in the vicinity thereof. The movable hook 4 is stored in the housing 3 and is provided so as to be able to be pulled out from the housing 3 to the back side as shown in FIG. The movable hook 4 is formed of a plate-like member, and is configured such that the plate-like member slides horizontally and is pulled out from the housing 3. The front end of the plate-like member on the back side protrudes upward from the upper surface of the housing 3 and has an upper end 4a bent to the front side. Further, the upper end 4a is inclined downward in the direction from the front side to the back side. The front side of the upper end 4a is a locking part 41 and faces the back of the vertical wall Vw. Note that the upper end 4 a protrudes upward even when stored in the housing 3. Although not shown, the movable hook 4 is provided with a stopper so as not to fall out of the housing 3.

  The movable hook 4 is made of, for example, an elastic (flexible) material such as nylon or polyoxymethine (POM). The movable hook 4 is attached to the housing 3 so as to bend in the vertical direction.

  The movable hook 4 is formed in a second region which is a right region (one region) of left and right regions with respect to the center of the length in the width direction of the electronic device 1. Here, since the center of gravity of the electronic device 1 in the width direction is in the first region, the movable hook 4 is at a position shifted from the position of the center of gravity of the electronic device 1 in the width direction.

  FIG. 4 is an enlarged view of the rib 5 provided in the electronic device 1 and the casing 3 in the vicinity thereof. As shown in FIG. 4, the rib 5 protrudes from the lower surface in the vicinity of both ends of the lower surface of the housing 3 (front member 3a), and is a wedge-shaped member. In addition, since the rib 5 is formed in a wedge shape, the electronic device 1 has sufficient strength to hold the electronic device 1 on the back surface of the vertical wall Vw described later. The rib 5 is formed integrally with the housing 3. Therefore, the rib 5 is formed of the same resin as the housing 3.

  In the present embodiment, ribs 5b are formed in the first region, and ribs 5a are formed in the second region, and a total of two ribs are provided. However, the number of ribs 5 is not limited to the above number, and it is sufficient that at least one rib 5 is provided in the first region. Three or more may be provided.

  The rib 5 includes an inclined part 51 and an engaging part 52 connected to the front side of the inclined part 51. The inclined portion 51 has a back end that is smoothly connected to the lower surface of the front member 3a and is inclined toward the front side away from the lower surface of the front member 3a. Moreover, the distance from the flange part 2 of the edge part of the front side of the latching | locking part 52 by the left and right ribs 5a and 5b is equal.

  When the locking part 41 and the locking part 52 are locked to a vertical wall Vw described later, the electronic device 1 is temporarily fixed to the vertical wall Vw.

[Attachment of electronic equipment to the vertical wall]
Next, attachment of the electronic device 1 to the vertical wall Vw will be described. FIG. 5 is a side view of the electronic device 1 when the electronic device 1 is temporarily fixed to the vertical wall Vw. In FIG. 5, the right side is the back (rear) side of the electronic device 1 and the vertical wall Vw, and the left side is the front (front) side of the electronic device 1 and the vertical wall Vw. 6 is a perspective view from above when the electronic device 1 is temporarily fixed to the vertical wall Vw, and FIG. 7 is a plan view when the electronic device 1 temporarily fixed is rotated. The size of the electronic device 1 has a vertical width, a horizontal width, and a thickness. The vertical width is a width in the vertical direction when the electronic device 1 is installed in the through hole Th formed in the vertical wall Vw. The horizontal width is the width in the horizontal direction when the electronic device 1 is installed in the through hole Th, and the thickness is the horizontal direction before and after the electronic device 1 is installed in the through hole Th. In other words, it is the width in the depth direction of the through hole Th. Therefore, the horizontal width direction described above is a direction based on this horizontal width.

  First, the lower part of the housing 3 of the electronic device 1 is fitted (fitted) into the through hole Th from the front side of the vertical wall Vw. At this time, the housing 3 is moved smoothly from the front side toward the back side while the inclined portion 51 of the rib 5 and the edge of the through hole Th are in contact with each other, thereby smoothly moving to the through hole Th. Can be made. When the contact between the inclined portion 51 of the rib and the edge of the through hole Th is released at the end of the movement from the front side to the rear side, the electronic device 1 moves downward by its own weight, and the locking portion 52 of the rib 5 is moved. Engages with the back side of the vertical wall Vw at the edge of the through hole Th.

  With the rib 5 engaged with the vertical wall Vw at the edge of the through-hole Th, the upper part of the electronic device 1 is formed on the vertical wall Vw with the engaging portion 52 of the rib 5 engaged. It rotates so that it may approach, and pushes the upper part of the housing | casing 3 in the through-hole Th.

  Here, the upper end 4a of the movable hook 4 protrudes upward from the housing 3 in a normal state, and further, the upper end 4a is inclined downward in the direction from the front side to the back side. Therefore, when the upper part of the housing 3 is pushed into the through hole Th, the upper end 4a of the movable hook 4 is pressed by the peripheral edge of the through hole Th, and the upper end 4a bends downward (the upper end 4a and the movable type). Both bases of the hook 4 may bend downward). Therefore, the housing 3 can be fitted into the through hole Th while the movable hook 4 is bent downward (pressed downward).

  When the upper end 4a of the movable hook 4 passes through the through hole Th and moves to the back side of the vertical wall Vw, the force that has pushed the upper end 4a is released. As a result, the movable hook 4 returns to the original state, that is, the upper end portion 4a protrudes upward from the housing 3. When the electronic device 1 is tilted forward (front side) in this state, the locking portion 41 of the movable hook 4 is caught on the back surface of the vertical wall Vw at the periphery of the through hole Th, and the movable hook is moved as the electronic device 1 is tilted. 4 is automatically pulled out of the housing 3. Since the movable hook 4 is provided with a retainer, the locking portion 41 of the movable hook 4 and the locking portion 52 of the rib 5 are vertically connected with all the portions pulled out from the housing 3 being pulled out. The electronic device 1 is temporarily fixed to the vertical wall Vw as shown in FIG.

  In addition, since the flange portion 2 on the front side of the electronic device 1 is larger than the through hole Th, the electronic device 1 does not penetrate the back side of the vertical wall Vw.

  As described above, in the electronic device 1, the two ribs 5 a and 5 b are in the lower part and the one movable hook 4 is in the upper part, and each engages with the vertical wall Vw on the periphery of the through hole Th. Temporarily fixed so as not to come out of Th. Note that when the electronic device 1 is temporarily fixed, the positions of the movable hook 4 and the rib 5 are determined so that the upper portion of the electronic device 1 protrudes more to the front side than the lower portion. That is, in the electronic device 1, the movable hook 4 and the rib 5 are arranged so that the locking portion 41 of the movable hook 4 is on the back side of the locking portion 52 of the rib 5. When temporarily fixed by the movable hook 4 and the rib 5, the electronic device 1 is inclined forward about the rib 5 as shown in FIG. 5.

  After the electronic device 1 is temporarily fixed to the through hole Th of the vertical wall Vw, the electronic device is fixed (mainly fixed) from the back side of the vertical wall Vw. At this time, since the movable hook 4 and the rib 5 are temporarily fixed by engaging the vertical wall Vw on the upper and lower edges of the through hole Th of the vertical wall Vw, the electronic device 1 does not fall off only by its own weight. Further, even if the worker touches the wall or accidentally presses the back surface of the electronic device 1 with a certain amount of force (for example, a force that touches the tool), the ribs 5a and 5b are removed. , Can prevent falling out as follows.

  The center of gravity of the electronic device 1 in the width direction is biased toward one of the left and right regions with respect to the center of the length in the width direction, and the movable hook 4 and the rib 5a are disposed in the other second region. Is provided. Therefore, the movable hook 4 exists at a position shifted from the position of the center of gravity of the electronic device 1 in the lateral width direction. The movable hook 4 and the rib 5a are provided on the upper part and the lower part of the housing 3 of the electronic device 1, respectively. In addition, a rib 5 b is provided in the first region and in the lower part of the housing 3 of the electronic device 1.

  Therefore, when a force is applied to the electronic device 1 and the ribs 5a and 5b are removed, the engagement of the electronic device 1 with the vertical wall Vw is released, and the lower part of the electronic device 1 tends to move forward. However, at that time, as shown in FIGS. 6 and 7, the second area is supported by the movable hook 4 and the center of gravity is located in the first area. It also rotates away from the wall. That is, the electronic device 1 rotates to the left in FIG. In addition, the dashed-dotted line in FIG. 6 has passed the center of the width direction of the movable hook 4, and has shown the center (rotation axis) of rotation. By this rotation, the left and right side surfaces of the casing 3 of the electronic device 1 respectively contact the left and right edges of the through hole Th of the vertical wall Vw, that is, the casing 3 is held by the through hole Th and the rotation is stopped. Is prevented from falling. Therefore, even if the installation worker of the electronic device 1 accidentally gives an impact to the vertical wall or pushes the back surface of the electronic device 1 and the ribs 5a and 5b are removed, the electronic device 1 is not attached to the casing 3. Can be held in the through hole Th by rotation, so that the electronic device 1 is prevented from falling.

  Further, even when a force is applied to the electronic device 1 and only 5b is detached, the electronic device 1 rotates to the left in FIG. 7 in the same manner as described above, and is vertically moved by the movable hook 4 and the rib 5a. Since the housing 3 can be held in the through hole Th as described above after engaging the back surface of the wall Vw, the electronic device 1 is prevented from falling.

  Further, when a force is applied to the electronic device 1 and only the rib 5a is detached, the movable hook 4 provided in the upper part of the second region and the rib 5b provided in the lower part of the first region The device 1 is held. However, considering the ease of fitting the through hole Th of the electronic device 1, it is preferable that the thickness of the rib 5 in the vertical direction is thin. For this reason, when the rib 5a is detached, the rib 5b is detached with a slight force. In this case, both ribs 5a and 5b are disengaged, and the housing 3 is held by the through-hole Th as described above to prevent the electronic device 1 from falling off.

  Here, for example, as shown in FIG. 8, in the electronic device 100 (the electronic device for reference) in which the upper engaging member 101 is located at the same position as the center of gravity in the lateral width direction, it is provided at both ends of the lower portion. When one of the engaging members is disengaged, the electronic device 100 slides in the direction of the disengaged engaging member, and as a result falls as it is. Note that the electronic device 100 shown in FIG. 8 is assumed to have a center of gravity in the width direction at the center.

  However, in the electronic device 1 of the present embodiment, as described above, the movable hook 4 is formed in the first region at a position shifted from the center of gravity of the electronic device 1 in the lateral width direction, and the rib 5b is When the engagement of the ribs in the second region is released, it rotates around the movable hook 4, that is, rotates around the axis in the second region as viewed from the plane, that is, the axis shifted to the left and right. It is the structure to do. Therefore, even if an impact is applied when the electronic device 1 is temporarily fixed to the vertical wall Vw in which the through hole Th is formed, the electronic device 1 does not fall.

  In addition, after temporarily fixing, the method of permanently fixing the electronic device 1 to the vertical wall Vw from the back using a fixture is performed by using a known method such as a screwing method disclosed in Patent Document 1, for example. it can. When the method disclosed in Patent Document 1 is used, a fixing hole for inserting a fixing tool is formed on the side surface of the front member 3a.

  Further, when the electronic device 1 is removed from the vertical wall Vw, if the fixing device is screwed, the fixing device is removed, and the portion where the locking portion 52 of the rib 5 is engaged is the center. When the upper portion of the electronic device 1 is rotated forward (front side) so as to be separated from the vertical wall Vw, the engaging portion 41 of the movable hook 4 is hooked on the back surface of the vertical wall Vw, and is movable when rotated forward as it is. The type hook 4 is pulled out from the housing 3. When all the portions of the movable hook 4 that are pulled out from the housing 3 are pulled out, the electronic device 1 is temporarily secured to the vertical wall Vw. Then, an operator located in front of the vertical wall Vm lifts the electronic device 1 temporarily fixed in an inclined state to release the engagement between the rib 5 and the through hole Th. Next, for example, if the engagement between the movable hook 4 and the through hole Th is released by tilting the upper portion of the electronic device 1 backward, the electronic device 1 can be removed from the vertical wall Vw. After removal, the movable hook 4 may be stored in the housing 2. The removal method is not limited to the above, and the electronic device 1 may be removed after the movable hook 4 passes through the through hole Th by bending the upper end portion 4a of the movable hook 4 downward.

  In the above, since the thickness of the casing 3 is thin, the movable hook 4 that can be stored in and pulled out from the casing 3 is provided. However, if the hook can be formed on the top surface of the casing, that is, the casing 3 can be formed. If the body has a thickness that allows the upper hook to be formed behind the lower rib as viewed from the side, the upper hook may not be movable. When there is a thickness that allows the hook to be formed on the upper surface of the housing, the hook may have the same configuration as the movable rib described in Patent Document 1, for example.

  In the above description, the rib 5 is described as being immovable, but it may be a movable rib that can be accommodated inside the housing.

  The present invention is not limited to the above-described embodiments, and various modifications can be made. That is, embodiments obtained by combining technical means appropriately changed within the scope not departing from the gist of the present invention are also included in the technical scope of the present invention.

  The present invention can be used for an electronic device such as a display device, an operation device, or a touch panel, which is attached to a through hole in a vertical wall.
