BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a mounting device for a panel instrument mounted on a panel.

[0002]

2. Description of the Related Art FIG. 3 is a perspective view showing the construction of a conventional panel instrument mounting device. In the figure, 1 is a panel instrument, 2 is a panel to which the panel instrument is attached, 3 is a fixing metal provided on the upper part of the panel instrument 1, and a screw 4 for fixing the panel instrument 1 is screwed thereto. When the screw 4 is tightened by the driver 5, the panel instrument 1 clamps the panel with the panel surface ₁₁ and is fixed to the panel 2.

[0003]

In such a conventional panel instrument mounting device, since screws are pressed directly from the back to the panel to fix the panel instruments, the screws are tightened with excessive force. Otherwise, the panel or panel instrument may be damaged. In order to prevent such a situation, the screws are tightened with a torque screwdriver or the strength of the panel instrument itself is increased.However, the former has a disadvantage that the operation becomes complicated, and the latter has a disadvantage. Has been an obstacle to downsizing and weight reduction of panel instruments.

The present invention has been made in view of such a point, and a screw is provided with a torque limiter mechanism so that the force of a screw pressing the panel does not exceed a predetermined value. It is an object of the present invention to provide a panel instrument mounting device capable of eliminating a breakage accident at the time of attaching an instrument and reducing the size and weight of the panel instrument.

[0005]

In order to achieve such an object, the present invention presses the display surface of the panel instrument with a screw from the back of the panel with the display surface protruding from the panel.
In a panel instrument mounting device for mounting a panel instrument on a panel, a fixing fitting attached to a housing of the panel instrument, and a female screw provided on the fixing fitting in parallel with the panel surface and screwed with the screw. A deformation wall made of an elastic body having a portion, and a vertical fixing wall having a hole into which the thread portion of the screw is loosely fitted and provided in parallel with the panel surface, and tightening the screw. A deformation wall deformed with an increase in force inclines the screw shaft, so that the screw thread meshes with the inner wall of the hole of the fixed wall.

[0006]

When the screw is strongly tightened to the panel and the torque is increased, the deformed wall is deformed and the screw shaft is inclined, so that the screw engages with the locking hole of the vertical fixed wall. For this reason, even if the screw head is further rotated by the driver, the screw cannot be rotated, and a certain force or more is not applied to the panel.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a configuration diagram of a main part showing an embodiment of a panel instrument mounting device of the present invention, and shows a fixing bracket which is a feature of the present invention. Components having the same functions as those in FIG. 3 will be described with the same reference numerals. In the figure, 10 is a fixing bracket which cross section is a substantially U-shape, the hook 11 ₁ provided on the bottom 11 is attached to the engaged the panel meter to the mounting hole of the panel instruments.

[0008] In the fixing bracket 10, reference numeral 12 denotes a deformable wall provided in parallel with the panel surface, which is bent substantially at a right angle from a mounting portion 13 of the fixing bracket 10, and a screw 4 is screwed at the center. female threaded portion 12 ₁ is provided to be engaged.

Reference numeral 14 denotes a vertical fixing wall provided in parallel with the deformable wall 12, which is fixed to the bottom 11 and the side plate 15 of the fixing bracket 10, and has a screw 4 screwed to the deformable wall 12 at the center. and a locking hole 14 ₁ is the loosely fitted. When the torque increases as the screw 4 is tightened to the panel, the deformable wall 12 deforms in the direction of the arrow U and tilts the screw shaft.

[0010] Therefore, the screw 4 is threaded engagement with the locking hole 14 ₁ of the inner wall of the vertical fixed walls 14, rotation is restricted. Incidentally, the internal thread portion 1 of the deformed wall 12 to the inner wall of the locking hole 14 ₁
By providing a 2 ₁ a different pitch of the internal thread portion 14 ₁₁ (see FIG. 2), thread and the internal thread portion 14 ₁₁ is to be locked on the principle of a lock nut.

As shown in FIG. 2, the deformable wall 12 is provided with a groove 16 between the deformable wall 12 and the mounting portion 13 so that the elastic force can be adjusted by the depth L of the groove 16.

FIG. 2 is an operation explanatory view for explaining the operation of the panel instrument mounting device of the present invention, and shows a cross section of a main part of FIG. The solid line indicates the initial state of the screw tightening, and the broken line indicates the state where the torque is increased and the screw is engaged with the vertical fixing wall 14.

When the screw 4 is rotated clockwise, the screw 4
The screw tip 4 ₁ proceeds to the panel 2 direction presses the panel surface. When the screw is further rotated to strongly press the panel, the deformable wall 12 bends in the direction of arrow U and tilts the screw shaft from the position AA 'to the position BB'.

[0014] screw 4, the screw shaft tilts to the position of the B-B ', meshes with the internal thread portion 14 ₁₁ of the bore of the threaded portion is a vertical fixed wall 14, the rotation is limited. Therefore, screw head 4 ₂
The screw 4 cannot be rotated even if the screwdriver is further turned with a screwdriver, and a certain force or more is not applied to the panel 2.

Since the fixing member 10 is made of a plate material, it can be easily deformed without intentionally providing the groove portion 16. Further, if two vertical fixing walls 14 are provided so as to sandwich the deformable wall 12, the fixing force increases, and stable fixing becomes possible.

[0016]

As described in detail above, in the panel instrument mounting device of the present invention, when the force of the screw pressing the panel exceeds a certain level, the screw is formed on the inner wall of the vertical fixed wall because the deformed wall tilts the screw axis. Mesh with. For this reason, the screws are not excessively fastened to the panel, and the panel and the panel instrument are not damaged. Also, since the structure is very simple, it can be manufactured in a small size and at low cost.
