Description

  The present invention relates to a mounting structure for an electronic device such as an indoor antenna device.

  Conventionally, an indoor antenna apparatus for receiving a television signal is generally placed on an upper side surface of a television receiver or the like.

  In recent years, it has become difficult to place an indoor antenna device on an upper side surface of a television receiver or the like in order to reduce the thickness of the television receiver. Therefore, there is a demand to attach such an indoor antenna device to a ceiling wall surface or a side wall surface.

By the way, in order to attach to the wall surface, an electronic device is provided with a saddle hole on the bottom surface of the casing of the electronic device, and is used to be hooked on a latch such as a bolt provided on the wall surface. The structure is known (for example, refer to Patent Document 1).
JP 2006-209166 A (paragraph 0010 and FIGS. 2, 4 and 5)

  In the mounting structure using the dart hole as described in Patent Document 1, the latching tool is positioned on the small-diameter hole side of the dharma hole in the mounted state so that it does not come off. In this case, when the position of the device is shifted due to vibration such as an earthquake, the latching tool moves from the small-diameter hole portion of the dart hole to the first opening side, and as a result, the device may be detached from the wall surface or ceiling wall surface. .

  Therefore, the present invention provides a mounting structure for an electronic device that prevents the electronic device from coming off due to vibration such as an earthquake.

According to a first aspect of the present invention, an electronic device includes an outer plate portion having a mounting hole, and the mounting hole is locked to a locking tool provided on the ceiling wall surface or side wall surface, whereby the electronic device is mounted on the ceiling wall surface or side wall surface. An electronic device mounting structure to which a device is mounted, wherein the locking device includes a shaft portion whose one end is fixed to the ceiling wall surface or the side wall surface, and a shaft portion provided at the other end portion of the shaft portion. The attachment hole is provided side by side in a plan view with a first opening through which the head of the locking tool can be inserted. The locking tool provided between a second opening through which the shaft portion of the locking tool can be inserted but the head cannot be inserted, and the first opening and the second opening. and a movement restricting portion that restricts movement of the shaft portion of the further, the mounting hole, a base end front on either side of it A pair of flexible arms connected to each side of the first opening is disposed, and each of the arms constitutes a part of the outer portion of the first opening in plan view. A curved belt-like portion, a linear portion whose base end is connected to the distal end of the curved belt-like portion and extending substantially in parallel, and a bulging portion provided at the distal end of the straight-like portion and constituting the movement restricting portion. and said that you are. Here, the first and second openings are not limited to circular through holes, and include various hole shapes such as a polygonal shape. Further, “to restrict the movement of the shaft portion of the locking tool” means that the shaft portion of the locking tool can be moved between the first opening and the second opening. This means that the movement of the shaft portion is difficult unless it is moved in a specific direction such as a direction connecting the centers of the first opening and the second opening.

If it does in this way, when attaching to a ceiling wall surface or a side wall surface, an attachment operator will first insert the head of a locking tool into the 1st opening, and will go from the 1st opening to the 2nd opening. It can be attached to the ceiling wall surface or the side wall surface by moving the shaft portion of the locking tool through the movement restricting portion. In this case, it is necessary to move the shaft portion of the locking tool in a specific direction in which movement is not restricted by the movement restricting portion.
In this attached state, the shaft portion of the locking tool is located at the second opening, and movement from the second opening to the first opening is restricted by the movement restricting portion. If only the shaft portion of the stopper is displaced irregularly, the shaft portion of the locking device does not move from the second opening side to the first opening side, and as a result, it comes off from the ceiling wall surface or the side wall surface. Is prevented.

In addition, by using the flexibility of the arm portion, it is possible to easily configure a movement restricting portion that restricts the movement of the shaft portion of the locking tool between the first opening and the second opening. it can.

Furthermore, a flexible arm portion can be disposed on the outer portion of the mounting hole without difficulty.

  As described above, the present invention has a configuration in which the movement restricting portion for restricting the movement of the shaft portion of the locking tool is provided between the first opening and the second opening in the mounting hole. In the state attached to the wall surface or the side wall surface, the shaft portion of the locking tool is in the second opening portion, and movement from the second opening portion to the first opening portion is restricted by the movement restricting portion. It is possible to prevent the mounting position of the device from shifting. Therefore, even if the electronic device is irregularly displaced due to vibration such as an earthquake, the shaft portion of the locking tool does not move from the second opening to the first opening, and the electronic device is not connected to the ceiling wall surface. Or it can prevent coming off from a side wall surface.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1A, 1B, and 1C are a side view, a plan view, and a bottom view, respectively, showing an indoor antenna device that is an electronic apparatus according to the present invention.

  As shown in FIGS. 1 (a) to 1 (c), reference numeral 1 denotes an indoor antenna device, which includes a main body portion 2, and rod antennas 3 and 3 are provided on a pair of leg portions 2A and 2A provided at the lower portion thereof. It has been.

  The main body 2 has a base 2B located on the lower side, a disk part 2C located on the upper side, and an intermediate part 2D located between them. When attaching to the ceiling wall surface S1 or the side wall surface S2 on the substantially triangular bottom plate portion 11 (outer plate portion, see FIG. 1 (c)) constituting the lower surface of the main body portion 2 (base portion 2B and legs 2A, 2A) In addition, mounting holes 11a and 11a for locking to the locking bolts 12 (locking tools) on the ceiling wall surface S1 or the side wall surface S2 are provided.

  The locking bolt 12 has a screw shaft portion 12a and a head portion 12b that is provided at the other end of the screw shaft portion 12a and has a larger diameter than the screw shaft portion 12a (see FIG. 3). However, one end of the screw shaft portion 12a is screwed and fixed to the ceiling wall surface S1 or the side wall surface S2.

  As shown in FIGS. 2 (a) and 2 (b) and FIG. 3, the mounting hole 11a has a large-diameter hole 11aa (first opening) through which the head 12b of the locking bolt 12 can be inserted, and this large hole. A small-diameter hole portion 11ab (second opening portion) provided side by side with the radial hole portion 11aa and capable of being inserted through the shaft portion 12a of the locking bolt 12 but not through the head portion 12b. Between them, a communication passage portion 11ac having a width substantially equal to the diameter of the shaft portion 12a of the bolt 12 and communicating with the large-diameter hole portion 11aa is disposed. A movement restricting portion 11ad for restricting the movement of the shaft portion 12a of the locking bolt 12 is disposed between the large diameter hole portion 11aa and the small diameter hole portion 11ab on the small diameter hole portion 11ab side of the communication passage portion 11ac. Yes. In addition, a cover plate portion 11c that extends in parallel with the bottom plate portion 11 and restricts the insertion of a given amount of locking bolts 12 or more is disposed inside the main body portion 2 and inside the large-diameter hole portion 11aa. ing.

  In the mounting hole 11a, a pair of arm portions 13 and 13 are arranged on both sides between the large diameter hole portion 11aa and the small diameter hole portion 11ab. Has been. Each arm portion 13 is formed by cutting out the bottom plate portion 11, and in a plan view, forms a part of the outer portion of the large-diameter hole portion 11aa (a part on the small-diameter hole portion 11ab side). A curved portion 13a, a linear portion 13b whose base end is connected to the distal end of the curved portion 13a and extending substantially in parallel, and a bulging portion 13c provided at the distal end of the linear portion 13b. It is what you have. The bulging portion 13c includes a rectangular plate-shaped first portion 13ca having the same width as the linear portion 13b and a semicircular plate-shaped second portion 13cb protruding from the first portion 13ca. The bulging portions 13c and 13c of the left and right arm portions 13 and 13 are normally narrower than the diameter of the small-diameter hole portion 11ab, and the movement restricting portion restricts the movement of the shaft portion 12a of the locking bolt 12. 11ad is configured. That is, the bulging portions 13c and 13c constituting the movement restricting portion 11ad have the shaft portion 12a of the locking bolt 12 in a direction (specific direction) connecting the centers of the large diameter hole portion 11aa and the small diameter hole portion 11ab. If it is not moved, the arm portions 13 and 13 do not flex well so that the distance between them increases, and the shaft portion 12a is restricted from moving (passing) between the bulging portions 13c and 13c. In addition, through-grooves 14 and 14 having a constant width are formed along the outer surfaces of the arm portions 13 and 13 so that the bending operation of the arm portions 13 can be easily performed.

With this configuration, when attaching to the ceiling wall surface S1 or the side wall surface S2, the head 12b of the locking bolt 12 previously attached to the ceiling wall surface S1 or the side wall surface S2, as shown in FIG. The shaft portion 12a of the bolt 12 is linearly moved from the center side of the large-diameter hole portion 11aa to the center side of the small-diameter hole portion 11ab along the communication passage portion 11ac and the movement restricting portion 11ad. Let At the time of this movement, since the arm parts 13 and 13 have flexibility, the two bulging parts 13c constituting the movement restricting part 11ad are pushed away in a direction away from each other by the movement of the shaft part 12a described above. The shaft portion 12a is allowed to move and moves into the small diameter hole portion 11ab.
Thereby, as shown in FIG. 5 or FIG. 6, the indoor antenna device 1 can be attached so as not to be detached from the ceiling wall surface S1 or the side wall surface S2. That is, in such an attached state, the shaft portion 12a of the bolt 12 is in the small-diameter hole portion 11ab, and the shaft portion 12a of the bolt 12 is irregularly displaced due to vibration such as an earthquake. Is regulated by the regulation part 11ad (bulging parts 13c, 13c). Therefore, the vibration such as an earthquake, without shank 12a of the locking bolt 12 is moved to the large-diameter hole portion 11aa side, the engagement relationship between the engaging bolt 12 and the mounting hole 11a is maintained, the ceiling wall surface S1 or The indoor antenna device 1 is prevented from being detached from the side wall surface S2.
This will be further described. The shaft portion 12a of the bolt 12 connects the center of the large-diameter hole portion 11aa and the small-diameter hole portion 11ab to the movement restricting portion 11ad (the bulging portions 13c and 13c) (or the communication path). If a predetermined force does not act in the direction in which the portion 11ac extends, the movement restricting portion 11ad (the bulging portions 13c and 13c) is not expanded and the movement of the shaft portion 12a is restricted. On the other hand, if the indoor antenna device 1 is moved by applying a predetermined force in a direction connecting the centers of the large-diameter hole portion 11aa and the small-diameter hole portion 11ab, the shaft portion 12a of the locking bolt 12 is moved. 11ad (bulging portion 13c, 13c) by expanding pressing so moved smoothly to the large-diameter hole portion 11aa side, can be removed from the ceiling wall S1 or sidewall surface S2.
Therefore, when the indoor antenna device 1 cannot be placed on the television receiver, even if the indoor antenna device 1 is attached to the ceiling wall surface S1 or the side wall surface S2, irregular displacement of the indoor antenna device 1 due to vibration such as an earthquake is caused. Since there is no possibility of falling off from the ceiling wall surface S1 or the side wall surface S2, there is an advantage in safety.

  In the above-described embodiment, the bulging portions 13c and 13c are divided into a rectangular plate-like first portion 13ca having the same width as the linear portion 13b and a semicircular plate-like second portion protruding from the first portion 13ca. However, the present invention is not limited thereto. For example, the second portion can be formed in a polygonal shape such as a trapezoidal plate. Further, as indicated by a chain line D in FIG. 2A, only the small diameter hole portion 11ab side of the protruding second portion has a rectangular cross section, and the large diameter hole portion 11aa side has a quarter circular shape. It is also possible to do. If it does in this way, the bulging part as a movement control part will become a more advantageous shape in controlling the movement of the axial part 12a from the said large diameter hole part 11aa to the small diameter hole part 11ab.

  In the above-described embodiment, the mounting structure of the indoor antenna device installed indoors has been described. However, the present invention is not limited thereto, and the mounting of other electronic devices similarly installed indoors is described. It can be applied not only to the structure but also to the mounting structure of electronic equipment installed outdoors.
