BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front panel mounting device which is effective when used for a front panel mounting device for a main body and a front panel of various electronic devices.

[0002]

2. Description of the Related Art In recent years, in equipment in various fields, a structure using hooks and claws for various fastening parts has been adopted in order to reduce members such as screws and man-hours. However, in the conventional configuration,
Since the hook was effective only for a load in one specific direction, it could not be said that the hook was sufficiently strong against impacts during transportation, etc. And other methods have been adopted. However, these methods have side effects such as difficulty in attachment and detachment work and an increase in insertion force, and a front panel mounting device that solves them has been required.

A conventional front panel mounting device will be described below. FIGS. 4A and 4B are perspective views showing the configuration of a conventional front panel mounting apparatus. FIG. 4A shows a state before the front panel is mounted on the electronic apparatus main body, and FIG. It is a state attached to. FIG. 5 is a cross-sectional view of a main part showing a process of mounting the front panel on the electronic device main body in the front panel device. FIG. 6 shows that a downward load is applied to the electronic device main body on which the front panel is mounted in the front panel device. FIG. 9 is a cross-sectional view of relevant parts showing the operation at that time.

In FIG. 1, reference numeral 1 denotes an electronic device main body, 4 denotes a front panel mounted on the electronic device main body 1, and 2 denotes an engaging claw provided on the electronic device main body 1, which is easily inserted into an engaging hole 6 of the front panel 4. It has an inclined surface to be inserted into. Reference numeral 3 denotes a pedestal having an engaging claw 2 provided on the upper surface thereof, and reference numeral 5 denotes a fixing hook provided on an upper portion of the back surface of the front panel 4. It has become. Reference numeral 5a denotes an inclined surface provided at the tip of the fixing hook 5, and reference numeral 6 denotes an engaging hole provided in the fixing hook 5. The electronic device main body 1 is used when the front panel 4 is mounted on the electronic device main body 1.
The front panel 4 can be fixed to the electronic device main body 1 by engaging with the engaging claws 2.

The operation of the conventional front panel mounting apparatus configured as described above will be described below.

First, as shown in FIG. 5A, the fixing hook 5 of the front panel 4 is placed on the pedestal 3 of the electronic device main body 1. When the front panel 4 is moved in the direction of arrow B in FIG. 5B, the fixing hook 5 bends upward while the tip of the fixing hook 5 slides on the inclined surface 2 a of the engaging claw 2. 5B, the engaging claw 2 is engaged with the engaging hole 6, and the front panel 4 is fixed to the electronic device main body 1. In the state shown in FIG.

[0007]

However, in the above-described conventional configuration, when a load as shown by an arrow F in FIG. 6A is imposed during transportation or the like, a component F1 of the load F (FIG.
(B)) can be received by the hook 5, and the electronic device main body 1 and the front panel 4 can be deformed synchronously.
There is no support in the direction of F2, and only the main body is deformed, and the deformation amount exceeds the height dimension X of the engaging claw 2, and the fixing hook 5 rides on the engaging claw 2 as shown in FIG. In addition, there is a problem that the front panel 4 is easily detached from the electronic device body 1. Further, when the height X is increased to prevent the vehicle from getting on the vehicle, a large insertion force is required when the front panel 4 is mounted on the electronic device 1, which hinders assembly.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and provides a front panel mounting apparatus capable of realizing, at a low cost, a configuration in which the front panel does not easily come off even when a downward load is applied during transportation or the like. The purpose is to provide.

According to the present invention, there is provided a front panel mounting apparatus for mounting a front panel on a front surface of an electronic apparatus main body, wherein the front panel mounting apparatus is provided on the front panel. A substantially plate-shaped fixing hook provided to bend when the panel is mounted on the electronic device, an engagement hole provided in the fixing hook, and a substantially plate formed in a direction perpendicular to the fixing hook. Shape stopper,
A pedestal provided on the electronic device main body and provided so as to be sandwiched between the fixing hook and the stopper when the electronic device main body and the front panel are mounted, and an engaging claw provided on the pedestal. It is another object of the present invention to provide a front panel mounting apparatus which can realize a configuration in which the front panel does not easily come off even if a downward load is applied during transportation or the like at low cost.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention is a front panel mounting apparatus for mounting a front panel on the front of an electronic device main body, wherein the front panel is mounted on the front panel and the front panel is mounted on the electronic device. A substantially plate-shaped fixing hook provided so as to bend when performing, an engagement hole provided in the fixing hook, a substantially plate-shaped stopper formed in a direction perpendicular to the fixing hook, A pedestal is provided on the device main body and is provided between the fixing hook and the stopper when the electronic device main body is mounted on the front panel, and an engagement claw provided on the pedestal.

According to this structure, the front panel is not easily detached even if a downward load is applied during transportation or the like.
