Description

  The present invention relates to an anti-loading electronic apparatus that can prevent an apparatus from being stacked in a horizontal state.

  Electronic devices including network devices typified by optical subscriber line termination terminals (ONUs) are generally in the shape of a thin box, and are placed horizontally or vertically on a table or the like. When such an electronic device is placed horizontally, it is generally installed so that the main body is not directly grounded by a foot protruding from the bottom surface of the main body.

  On the other hand, when an electronic device is placed vertically, in many cases, a vertical stand is generally fitted to the electronic device so that the main body does not fall down. FIG. 9 is a diagram showing an example of a conventional vertical stand.

  FIG. 9 shows a vertical stand 820 and an electronic device 811 placed vertically by the vertical stand 820. In FIG. 9, two vertical stands 820 are used as one set, which are fitted into an electronic device 811 for use.

  Further, as shown in FIG. 9, the vertical stand 820 includes a stand plate 822 that stands on the base 821 and faces the foot 812. The stand plate 822 is provided with a locking hole 823 that fits with the foot 812. By fitting the locking hole 823 and the foot 812, the vertical stand 820 can be prevented from being detached from the electronic device 811.

  That is, the locking hole 823 has a function of preventing the vertical stand 820 from dropping from the electronic device 811. In addition, the electronic device 811 can be inserted into and removed from the stand 820 for vertical installation by bending due to the elastic force of the material (typically synthetic resin such as plastic) of the base 821 and the stand plate 822.

  FIG. 10 is a view for explaining a vertical stand 9120 and a wall hanging tool 9300 for placing an electronic device 9200 such as a game machine or a personal computer vertically. As shown in FIG. 10, the vertical stand 9120 includes a base 9100 and a pair of vertical plates 9110 erected on the base 9100.

  The pair of vertical plates 9110 sandwich the side surface of the electronic device 9200 from the bottom surface side, and stably fix the electronic device 9200 to the base 9100. When the electronic device 9200 is installed on the wall, the wall hanging tool 9300 is fixed to the wall by screws or the like, and the electronic device 9200 is locked to the wall hanging tool 9300. In this case, the electronic device 9200 may be locked to the wall hanging tool 9300 with a hook or the like.

  The above-described conventional electronic devices and their stands are described in, for example, Patent Document 1 to Patent Document 3 below.

It is a perspective view explaining the stacking prevention electronic device concerning a second embodiment. It is a conceptual diagram explaining the sliding storage of the wall hanging part of a stacking prevention electronic device. It is a figure explaining the state which laid horizontally with the wall hanging part being the bottom face side about a loading prevention electronic device. It is a perspective view explaining the stacking prevention electronic device concerning a third embodiment. It is a figure which shows the example of the conventional stand for vertical installation. It is a figure explaining the stand for vertical installation and wall hanging tools for placing electronic devices, such as a game machine and a personal computer, vertically.

  In the stacking prevention electronic device described in the embodiment, the main body and the stand are integrated, and when placed horizontally, one point of the main body and one point of the base of the stand are typically mounted on a desk or the like. Ground on the table.

  For this reason, the base is provided with a first horizontal support portion formed in a convex shape, for example, and the main body is provided with a second horizontal support portion formed in a convex shape, for example. When placed horizontally, the loading prevention electronic device is grounded on a straight line on the mounting table at the first horizontal support portion and the second horizontal support portion, and swings in a seesaw state with this straight line as an axis. It becomes possible.

  For this reason, it is substantially impossible to stack other electronic devices or the like so as to form a plurality of stages on the horizontally mounted stacking prevention electronic devices. That is, the stacking prevention electronic device described in the embodiment is stably placed on the mounting table by an integrated stand when it is installed vertically.

  On the other hand, the stacking prevention electronic device described in the embodiment is supported by, for example, two points by the first horizontal support portion and the second horizontal support portion when it is horizontally placed, so that it does not swing. It becomes stable and does not form a plane that is stable enough to mount another electronic device on the top surface of the stacking prevention electronic device.

  A virtual straight line on the desk surface connecting the first horizontal support portion and the second horizontal support portion of the load preventing electronic device is typically a support shaft that passes relatively near the center of gravity of the load preventing electronic device. The load preventing electronic device is in a seesaw state around the axis. In addition, the stacking prevention electronic device does not have a support point that is typically not positioned on a straight line as a support shaft with respect to the mounting table when placed horizontally. This is because, for example, if the stacking prevention electronic device is supported on the mounting table at a total of three points, two points on the supporting shaft and one point outside the supporting shaft, a relatively stable mounting is realized. Because it will end up.

  In addition, the stacking prevention electronic device includes a wall hanging portion that can adjust the distance from the main body. The wall hanging portion is configured so that a slide storage surface parallel to the base can be slid and stored in the base. Therefore, the distance from the main body can be adjusted as appropriate by sliding the slide storage surface into the base. In addition, by sliding and storing the wall hanging portion, the first horizontal support portion provided on the base protrudes more than the wall hanging portion even when the stacking prevention electronic device is placed horizontally with the side where the wall hanging portion is located as the bottom surface. Then, it is grounded to the mounting table, thereby realizing unstable support. Hereinafter, each embodiment will be described with reference to the drawings.

(First embodiment)
With reference to FIG. 1 thru | or FIG. 4, the stack | stuck prevention electronic device 1000 of 1st embodiment is demonstrated. FIG. 1 is a perspective view illustrating an outline of the configuration of the stacking prevention electronic apparatus 1000 according to the first embodiment.

  As shown in FIG. 1, the stacking prevention electronic device 1000 includes a main body 200, a base 100 that stably supports the main body 200 when placed vertically, and a wall hanging portion 330.

  In FIG. 1, the base 100 is generally rectangular in shape, and has semicircular first horizontal support portions 110 (a) and 110 (b) protruding from two long sides (hereinafter referred to as “first”). A horizontal support portion 110). The first horizontal support portions 110 (a) and 110 (b) support the stacking prevention electronic device 1000 with respect to the mounting surface when being horizontally placed.

  Further, on the upper surface of the main body 200, a circular and flat second horizontal support portion 210 is provided so as to protrude from the edge of the main body 200 to both side surfaces. The second horizontal support 210 may be a circular or elliptical frame.

  The first horizontal support portions 110 (a) and 110 (b) and the second horizontal support portion 210 contact the mounting base when the stacking prevention electronic device 1000 is placed horizontally, Support unstable.

  In addition, four slide shafts 400 (a), 400 (b), 400 (c), and 400 (d) (hereinafter referred to as the slide shaft 400 as appropriate) are erected on the base 100. The four slide shafts 400 (a), 400 (b), 400 (c), 400 (d) have four slide rails 220 (a), 220 (b), 220 ( c) and 220 (d) (hereinafter appropriately referred to as slide rail 220). In FIG. 1, the slide rails 220 (c) and 220 (d) are located on the back side of the paper surface of the main body 200, and thus description thereof is omitted.

  Locking holes 221 (a), 221 (b), etc. provided in the slide rails 220 (a), 220 (b), etc., and engagements provided in the slide shafts 400 (a), 400 (b), etc., respectively. The main body 200 can be fixedly arranged at an arbitrary height position by pin-inserting or screwing the stop holes 410 (a), 410 (b) and the like so that they coincide on the same axis.

  Thereby, the stacking prevention electronic device 1000 can secure a space in which a power strip, wiring, and the like can be arranged between the base 100 and the main body 200. Therefore, the load preventing electronic device 1000 can reduce the necessity of separately securing a space for arranging power taps, wirings, and the like on the mounting table, so that the space can be used effectively and can be a space-saving device.

  The wall hanging portion 330 includes a surface 300 perpendicular to the base 100 and a slide storage surface 320 parallel to the base 100 slidably stored in the base 100. The surface 300 perpendicular to the base 100 may be joined to the wall so as to be stable when placed on the wall. Further, the surface 300 perpendicular to the base 100 may be provided with a screw hole 310 or the like for screwing the wall.

  As understood from FIG. 1, the slide storage surface 320 and the surface 300 perpendicular to the base 100 are notched hole-shaped window portions penetrating through the portion corresponding to the first lateral support portion 110 (b). 340 is provided. Due to the presence of the notched hole-shaped window portion 340, the first horizontal support portion 110 (b) and the wall hanging portion 330 are arranged on the same edge portion of the base 100 without being obstructed with each other. The

  Further, since the slide storage surface 320 is slid and stored in the base 100, the wall hanging portion 330 is disposed closer to the main body 200. Therefore, the first horizontal support portion 110 (b) It protrudes outside the side surface from the surface 300 perpendicular to the base 100. The slide storage surface 320 may be configured using, for example, a slide telescopic rail.

  FIG. 2 is a conceptual diagram illustrating slide storage of the wall hanging portion 330 in a state in which the stacking prevention electronic device 1000 is placed vertically.

  In FIG. 2, the same parts as those in FIG. As can be understood from FIG. 2, when the slide storage surface 320 is slid and stored in the base 100, the first lateral support 110 (b) is more than the surface 300 perpendicular to the base 100. Protrudes to the left.

  As a result, even when the stacking prevention electronic device 1000 is placed horizontally with the wall-hanging portion 330 side as the bottom surface side, the first horizontally-supporting portion 110 (b) and the second horizontally-placed device are not obstructed by the wall-hanging portion 330. The support unit 210 can be in good contact with the mounting table, and the stacking prevention electronic device 1000 can be maintained unstable.

  Here, the state in which the stacking prevention electronic device 1000 is kept unstable when it is placed horizontally does not necessarily require a seesaw motion like a natural state. In other words, the instability may be such as to give up loading of other electronic devices on the upper surface of the horizontally-installed stacking prevention electronic device 1000 and abandon a plurality of stacks. Preferably, when there is a slight misalignment (typically within a few millimeters to 1 centimeter) of the electronic device or the like to be stacked on the horizontally-installed stacking prevention electronic device 1000 The tilting state of the seesaw only needs to be changed to the opposite side.

  FIG. 3 is a conceptual diagram for explaining a state in which the horizontally placed stacking prevention electronic device 1000 is observed from the base 100 side. In FIG. 3, the same portions as those in FIGS. 1 and 2 are denoted by the same reference numerals, and the description thereof is omitted.

  In FIG. 3, the stacking prevention electronic device 1000 is placed horizontally such that the wall hanging portion 330 is on the bottom surface side, that is, the mounting table side. As understood from FIG. 3, the first horizontal support portion 110 (b) is grounded with respect to the mounting table 1300 with a point or a line by storing the slide storage surface 320 indicated by the broken line in the base 100. However, it can be swung like a balance or a balance with the ground contact point as a fulcrum or support shaft.

  FIG. 4 is a conceptual diagram illustrating the stacking prevention electronic apparatus 1000 that is placed horizontally with the wall hanging portion 330 on the upper side, from the bottom side. Also in FIG. 4, the same portions as those in FIGS. 1 to 3 are denoted by the same reference numerals, and the description thereof is omitted.

  In FIG. 4, when the horizontally placed stacking prevention electronic device 1000 swings in a seesaw state, a portion of the first lateral support portion 110 (a) that is actually in contact with the placement base is designated as a first ground portion 111. (A) is indicated by hatching. Similarly, when the horizontally placed stacking prevention electronic device 1000 swings in a seesaw state, a portion of the second horizontal support portion 210 that actually contacts the mounting table is hatched as the second grounding portion 211. It shows with.

  As can be understood from FIG. 4, the first grounding portion 111 (a) has a certain area corresponding to the thickness of the first horizontal support portion 110 (a) and the positional variation of the grounding wire during swinging. . Similarly, the second grounding portion 211 has a certain area corresponding to the thickness of the second horizontal support portion 210 and the fluctuation of the position of the grounding wire during swinging. In the case where the thickness of the first horizontal support portion 110 (a) and the second horizontal support portion 210 is substantially negligible, point contact with the mounting table is performed.

  In addition, at a certain arbitrary time point, the horizontally placed stacking prevention electronic device 1000 is placed on the mounting table with a single virtual straight line passing through the first grounding portion 111 (a) and the second grounding portion 211 as a support axis A. Is supported. Further, as shown in FIG. 4, the support shaft A is typically a projection point of the center of gravity G of the stacking prevention electronic device 1000 on the mounting table in a state where one side surface of the main body 200 having the largest area is horizontal. It is preferable to pass through.

  As understood from FIG. 4, at a certain arbitrary time point, the horizontally placed stacking prevention electronic device 1000 has another grounding point or grounding wire on the support shaft A between the mounting base and the mounting base. Also good. However, at some arbitrary point in time, if another grounding point or the like is located at a place other than on the support shaft A, the first grounding portion 111 (a) on the support shaft A and the second grounding portion on the support shaft A. Since a polygon is formed between 211 and another grounding point, the stacking prevention electronic device 1000 placed horizontally in this state becomes stable, which is not preferable.

  That is, at a certain arbitrary time point, the horizontally placed stacking prevention electronic device 1000 has a seesaw shape with a plurality of support points or support lines positioned virtually on the same straight line on the placement surface as a support shaft. It is preferable to be supported on the mounting table in an unstable manner.

  In addition, as described above, the stacking prevention electronic device 1000 is stably placed by the stand including the base 100 and the slide rail 400 when placed vertically. Moreover, the space below the main body 200 can be effectively utilized by adjusting the height of the main body 200 with respect to the base 100.

  Further, since the stacking prevention electronic device 1000 is integrally provided with the wall-hanging portion 330 that can be slidably accommodated, it is possible to arrange the wall-mounting device while reducing separately attached components and the like. In addition, since the stacking prevention electronic device 1000 is unstablely placed in a seesaw shape when placed horizontally, the stacking of other electronic devices and the like on a plurality of stages is reduced and is caused by loading. It is possible to dispel the concern that thermal failure due to heat storage or the like will occur.

  In addition, the loading prevention electronic device 1000 has a structure that inevitably becomes unstable and prevents loading when it is placed horizontally without requiring consideration of the device user or the like. It becomes a foolproof and fail-safe electronic device that is not bound by mistakes.

  Moreover, since the stacking prevention electronic device 1000 is slid and stored on the base 100 so as not to prevent the wall-hanging portion 330 from being unstablely placed when it is placed horizontally, the stacking stacking can be performed more reliably and safely. Can be prevented.

  In the above description, the stacking prevention electronic device 1000 has been described as including four slide rails 400, but any number may be used, and other known height adjustment mechanisms may be employed. .

  Further, in the stacking prevention electronic device 1000, the first horizontal support portion 110 and the second horizontal support portion 210 have been described as being circular or semicircular plate shapes, but may be elliptical, Either one or both of the support part 110 and the second horizontal support part 210 may have a protrusion shape that can make point contact with the placement surface.

  Further, the degree of protrusion of the first horizontal support 110 and the second horizontal support 210 corresponds to the size and weight of the main body 200 of the stacking prevention electronic device 1000 so that desired instability can be realized. You may adjust suitably.

  If the first horizontal support part 110 and the second horizontal support part 210 are excessively projected, not only the inclination during horizontal installation becomes excessively large, but also the impact when the inclination changes to the opposite side in the seesaw state. There is also a growing concern. In such a case, a cushioning material such as a foot can be appropriately disposed.

  On the other hand, if the protrusion of the first horizontal support portion 110 and the second horizontal support portion 210 is too small, an effective inclination and a seesaw-like unstable state that prevents loading when the device is horizontally placed It will not occur. For this reason, for example, the inclination in the seesaw direction of the stacking prevention electronic device 1000 when it is placed horizontally is about ± 10 ° to ± 30 °, and a relatively small energizing force when loading other electronic devices. Therefore, it is preferable that the inclination of the stacking prevention electronic apparatus 1000 varies in a seesaw shape.

(Second embodiment)
A stacking prevention electronic device 2000 according to the second embodiment will be described with reference to FIGS. 5 to FIG. 7, the same reference numerals are given to the portions corresponding to those of FIG. 1 to FIG. 4 already described in the first embodiment, and the description thereof is omitted here to avoid duplication of description.

  FIG. 5 is a perspective view illustrating the stacking prevention electronic device 2000 according to the second embodiment. As shown in FIG. 5, in the stacking prevention electronic device 2000, a pair of side surfaces of the main body 200 that is the bottom surface side or the top surface side when being placed horizontally is curved in a convex shape as a whole.

  For this reason, when the stacking prevention electronic device 2000 is placed horizontally, one of the second horizontal support portions 2210 (a) and 2210 (b), which is the upper edge portion of the main body 200 in FIG. Ground the pedestal. In addition, when the stacking prevention electronic device 2000 is placed horizontally, one of the second horizontally placed support portions 2210 (a) and 2210 (b) on the bottom side and the first horizontally placed support portion 110 (a). , 110 (b) is unstablely supported on the mounting table.

  FIG. 6 is a conceptual diagram for explaining the sliding storage of the wall hanging portion 330 of the stacking prevention electronic device 2000. FIG. 6A is a diagram illustrating a state in which the wall hanging portion 330 is extended. In this state, the wall hanging portion 330 is arranged on the wall with a hook, a screw, or the like. FIG. 6B is a diagram for explaining a state in which the slide storage surface 320 of the wall hanging portion 330 is slid and stored in the base 100.

  The structure and mechanism of the wall hanging portion 330 are not different from those of the first embodiment, and the wall hanging portion 330 may appropriately use a known slide storage mechanism such as a slide telescopic rail. A known mechanism may be adopted.

  FIG. 7 is a diagram illustrating a state in which the stacking prevention electronic device 2000 is placed horizontally with the wall hanging portion 330 as the bottom surface side.

  As can be understood from FIG. 7, the stacking prevention electronic device 2000 is not obstructed by the surface 300 perpendicular to the base 100, similarly to the stacking prevention electronic device 1000 described in the first embodiment. The lateral support 110 (b) can be grounded to the mounting table 1300 in the first ground 111 (a).

  Further, as can be understood from FIG. 7, the stacking prevention electronic device 2000 is grounded to the mounting table 1300 in the second horizontal support portion 2210 (b).

  Accordingly, when the stacking prevention electronic device 2000 is horizontally placed, the first horizontally placing support unit 110 (b) and the second horizontally placing support unit 2210 (b) are supported in an unstable manner. . In this case, as described above, the stacking prevention electronic device 2000 can swing unstably in a seesaw shape with a straight line on the virtual mounting surface as a support shaft. The stacking prevention electronic device 2000 does not have other support points that are not located on the support shaft at a certain point in time.

  FIG. 7 illustrates a state in which the main body 200 is inclined downward toward the right side of the sheet when the stacking prevention electronic device 2000 is placed horizontally. However, the state is not limited to the state illustrated in FIG. 7, and when the stacking prevention electronic device 2000 is placed horizontally, the main body 200 may be tilted upward toward the right side of the paper surface or may be horizontal. This can be easily adjusted by appropriately adjusting the relative degree of protrusion between the first horizontal support portion 110 (b) and the second horizontal support portion 2210 (b).

  That is, in the state shown in FIG. 7, the stacking prevention electronic device 2000 does not swing in a seesaw shape in the left-right direction on the paper surface, but swings in a seesaw shape on the front side and the depth side of the paper surface.

  The stacking prevention electronic device 2000 is different from the stacking prevention electronic device 1000 described in the first embodiment only in the second horizontal support portion 2210 (b), and the mechanism and the extent to which it is supported in an unstable manner. Since the operation and effect thereof are the same, the description is omitted here to avoid duplication of explanation.

(Third embodiment)
FIG. 8 is a perspective view for explaining the stacking prevention electronic apparatus 3000 according to the third embodiment. In FIG. 8, portions corresponding to those of the stacking prevention electronic devices 1000 and 2000 described in FIGS. 1 to 7 are denoted by the same reference numerals, and description thereof is omitted here to avoid duplication of description.

  As can be understood from FIG. 8, the stacking prevention electronic device 3000 includes second lateral support portions 3210 (a) and 3210 (b) that are curved and raised in a convex shape on a part of the side surface of the main body 200. In FIG. 8, the second horizontal support portions 3210 (a) and 3210 (b) are shown as being semi-cylindrical, but the present invention is not limited to this, and the horizontal stacking prevention electronic device is not limited thereto. As long as 3000 is unstablely supported, each may be hemispherical or protruding.

  Further, when the stacking prevention electronic device 3000 is placed horizontally, the grounding of the second horizontally placed support portions 3210 (a) and 3210 (b) with respect to the placing table is linear or dotted, but is linear. In addition, a grounding point or a grounding line with the mounting table in one of the first horizontal support portions 110 (a) and 110 (b) is positioned on the extension line. In other words, at any time when the straight line becomes a support shaft and may be placed horizontally and unstable in a seesaw shape, the stacking prevention electronic device 3000 has a virtual straight line shape on the mounting surface. There are no other support points that are not located on the spindle.

  As a result, when the stacking prevention electronic device 3000 is placed horizontally, the stacking prevention electronic device 3000 is supported on the mounting table with the straight line as a support shaft and is unstable so as to easily swing in a seesaw shape. Can be maintained.

  In addition, in the stacking prevention electronic devices 1000, 2000, and 3000 described in the embodiments, the stand and the wall hanging tool are not attached, but are integrated into the main body, so that there is no risk of losing these members. Moreover, the space below the main body can be effectively utilized by arranging the main body so as to float from the base.

  In addition, the flat base 100 shown in the embodiment may have a shape that can secure a certain support surface with the mounting table so that the stacking prevention electronic device 1000 or the like can be stably placed vertically on the mounting table. Specifically, the shape may be a mesh shape, a frame shape, or the like, and a cushioning member such as a foot may be provided on the bottom surface. In addition, by forming the base 100 itself into a circular plate shape or an elliptical plate shape, any one of the edge portions of the base 100 is provided with the first horizontal support portions 110 (a), 110 (b ) May be formed.

  Moreover, since the stacking prevention electronic devices 1000, 2000, and 3000 according to the embodiment can effectively prevent the stacking when placed horizontally, the heat radiation is prevented from being obstructed and the occurrence of a thermal failure is avoided. it can.
