JP 2007-132827 A

Hereinafter, the panel instrument mounting apparatus will be described with reference to FIG. FIG. 3 is a perspective view of a conventional panel instrument mounting apparatus. The upper mounting member 10 fixes the panel instrument 31 to the panel 30 from the upper surface of the panel instrument 31, and hook portions 11 and 12 (not shown) are inserted into the mounting holes 32 and 33 of the panel instrument 31.

The lower mounting member 20 is used to fix the panel instrument 31 to the panel 30 from the bottom surface of the panel instrument 31, and the hook parts 21 and 22 are mounted on the panel instrument 31 facing the hook mounting holes 32 and 33 (not shown). Inserted into the hole.

Further, after the upper mounting member 10 and the lower mounting member 20 are mounted on the panel instrument 31, the driver 40 is inserted into the upper mounting member 10 and the lower mounting member 20, and screws described in FIG. By screwing in this direction, the end face of the screw comes into contact with the panel 30, and the panel device 31 is fixed to the panel 30.

FIG. 4 is a configuration diagram of the upper mounting member 10, and the left side is the panel 30 side. 4A is a plan view, FIG. 4B is a right side view, and FIG. 4C is an AA cross-sectional view of FIG.

4A, a screw 50 is provided in the groove 51 of the upper mounting member 10, and hook portions 11 and 12 are formed on the bottom surface of the groove 51 as shown in FIG.

Here, since the hook portions 11 and 12 are formed in an L shape, when the upper mounting member 10 is slid away from the panel 30 after being inserted into the hook mounting holes 32 and 33 in FIG. The upper attachment member 10 is prevented from falling off by fitting with the plate portion forming the upper surface of the meter 31.

Further, this drop-off prevention measure is similarly applied to the lower mounting member 20, and the hook portions 21 and 22 of FIG. 3 are inserted into hook mounting holes (not shown) of the plate portion that forms the bottom surface of the panel instrument 31, and the panel 30. Dropping is prevented by sliding in a direction away from the head. Similarly to the upper mounting member 10, the lower mounting member 20 is also provided with a screw in the formed groove.

FIG. 5 is a view showing a state of fitting between the hook portion 11 formed on the upper mounting member 10 and the plate portion forming the upper surface of the panel instrument 31. 5A shows a state before fitting, FIG. 5B shows a state during fitting, and FIG. 5C shows a state after fitting.

The width of the hook portion 11 is narrower than the mounting hole 32 on the upper surface of the panel instrument 31. Therefore, when the upper mounting member 10 is opened on the mounting hole 32, the upper mounting member 10 is fitted as shown in FIG. 5C through FIG.

Thus, when attaching the panel instrument 31 to the panel 30, the upper attachment member 10 and the lower attachment member 20 are utilized.

By the way, when the screw 50 in FIG. 4A is screwed in the direction of the panel 30, the upper mounting member 10 to which the screw 50 is attached also moves to the panel side together with the screw 50. However, with respect to the upper mounting member 10, the panel instrument 31 serves as a support, and therefore the upper mounting member 10 does not fall off during the mounting operation to the panel 30 unless the panel instrument 31 is tilted by mistake.

However, regarding the lower mounting member 20, when the screw provided in the groove is screwed in the direction of the panel 30, the lower mounting member 20 to which the screw is mounted also moves to the panel side together with the screw, as shown in FIG. The hook portion 21 formed on the lower mounting member 20 falls out of the hook mounting hole 34 of the panel instrument 31.

For this reason, when the lower mounting member 20 is mounted, the lower mounting member 20 is pressed from below with a finger while the hook 21 is fitted to the plate portion forming the bottom surface of the panel instrument 31, and the lower mounting member 20 is attached together with the screw. The movement to the panel 30 side was prevented.

However, since a plurality of panel instruments 31 are often attached to the panel 30 at a narrow interval, when there are other panel instruments on both sides, it is extremely difficult to press the lower mounting member 20 from below with a finger. In this case, it becomes easy for the lower mounting member 20 to drop off, and the working efficiency decreases.

The present invention has been made in view of these problems, and an object of the present invention is to provide a panel instrument mounting device in which a panel mounting mounting member does not fall out of a panel instrument hook mounting hole.

In order to achieve such a problem, the present invention has the following configuration.
(1) In a panel instrument mounting device for mounting a panel instrument on a panel,
An attachment member that is attached to the panel instrument and is screwed onto the panel instrument, and presses the screw against the panel to fix the panel instrument;
The mounting member is formed in a substantially L shape, inserted into the mounting hole of the panel instrument, and engaged with a plate portion that forms the upper surface or the bottom surface of the panel instrument when slid in a direction away from the panel. Hook,
A panel instrument mounting device comprising: a pair of first protrusions formed at a side end portion of the mounting hook and formed to be slightly wider than the mounting hole.
(2) The mounting member has a second protrusion formed on the surface where the mounting hook is formed, and the second protrusion is inserted into a slide hole formed on the surface where the mounting hole of the panel instrument is formed. The panel instrument mounting device according to claim 1, wherein:
(3) The panel instrument mounting device according to claim 1 or 2, wherein the mounting hook is made of a synthetic resin.

The present invention has the following effects. Since a protrusion for preventing the hook member from falling off the hook mounting hole is formed on the hook portion of the mounting member, the mounting member for mounting the panel does not drop from the hook mounting hole of the panel instrument.

Hereinafter, a panel instrument mounting apparatus according to the present invention will be described with reference to FIG. Here, FIG. 1A shows a state before fitting, FIG. 1B shows a state during fitting, and FIG. 1C shows a state after fitting. The perspective view of the present invention has the same configuration as FIG. That is, the present invention is characterized in that a pair of protrusions 211 described later is provided on the hook portion 210.

Further, in FIG. 1A, a hook attachment hole 110 is formed in the plate portion that forms the upper surface and the bottom surface of the case 100 of the panel instrument. A substantially L-shaped hook portion 210 is formed on the attachment member 200, and a pair of protrusions 211 are integrally formed on the side surface end portion of the hook portion 210.

In addition, the position where the protrusion 211 is formed is formed at a position farther from the attachment member 200 than the width of the plate portion forming the upper surface or the bottom surface of the case 100.

Further, the protrusion 211 is formed to be slightly wider than the hook attachment hole 110, and a synthetic resin such as plastic is used. Here, the range is slightly wide depending on the elasticity of the resin. For example, in the case of polycarbonate, about 0.1 mm is preferable, and about 0.03 mm to 0.3 mm may be used.

Further, chamfers are formed on the upper and lower sides of the protrusion 211 so that the protrusion 211 can be easily inserted and removed.

For this reason, when inserting into the hook mounting hole 110, it is inserted into the hook mounting hole 110 so as to slide by chamfering formed under the projection 211 as shown in FIG. . Moreover, once it fits like FIG.1 (C), the protrusion 211 will engage with the edge of the board part which forms the upper surface of the case 100, and the attachment member 200 and the case 100 will be in a semi-fixed state.

On the other hand, when removing the panel instrument from this semi-fixed state, the attachment member 200 is sandwiched with fingers or the like and is pulled out with force.

Therefore, the protrusion 211 is preferably made of an elastic material such as synthetic resin. For example, a rigid member that cannot be easily deformed by human force, such as steel, is not suitable for the material of the hook portion 210 forming the protrusion 211 in principle.

However, even when a rigid member is used for the hook portion 210, it is sufficient to use an elastic material for the plate portions forming the upper surface and the bottom surface of the case 100.

That is, the present invention can be applied if an elastic member is used for at least one of the hook portion 210 or the plate portion forming the upper surface and the bottom surface of the case 100.

Thus, according to the present invention, since the projection 211 that prevents the hook member 210 from dropping off from the hook attachment hole 110 is formed on the hook portion 210 of the attachment member 200, the attachment member 200 for attaching the panel instrument is removed from the hook attachment hole of the panel instrument. Do not fall off. Therefore, it is possible to tighten the screw without pressing the attachment member 200 with a finger or the like from below, and work efficiency is improved.

Next, a method of attaching the attachment member 200 to the case 100 will be described with reference to FIG. The hook portion 210 of the attachment member 200 is inserted into the hook attachment hole 110. Here, when the hook portion 210 is inserted into the hook mounting hole 110, it is inserted as described with reference to FIGS.

Subsequently, the mounting member 200 is slid in a direction away from the panel. At this time, since the protrusion 212 (second protrusion) of the attachment member 200 moves along the protrusion slide hole 111 formed on the extension line of the hook attachment hole 110, the attachment member 200 does not shift from side to side. The substantially L-shaped hook portion 210 is fitted to a plate portion that forms the upper surface and the bottom surface of the case 100.

In the present embodiment, the attachment member 200 attached to the case 100 from the upper surface is described as an example, but the same applies to the case of attaching from the bottom surface.

Further, according to the embodiment of the present invention, one mounting hook is used, but two or more mounting hooks may be used. Further, the material used for the protrusion is not necessarily a synthetic resin as long as it is an elastic material. For example, a spring may be used.

Moreover, although the protrusion 211 of the present invention is worn when it is repeatedly removed, there is no problem because the replacement frequency of the panel instrument is low.
