Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a mechanism for mounting a windshield disposed in front of a display unit of an audio device or the like.
In particular, the present invention relates to a front glass attaching mechanism suitable for a fluorescent display tube.

[0002]

2. Description of the Related Art In acoustic equipment and the like, an acrylic resin having a high light transmittance is generally used as a material of a front glass disposed on a front surface of a display unit such as a fluorescent display tube. Such a resin having a high light transmittance has high rigidity and is hardly deformed, so that a hook for mounting cannot be formed.

Further, when a hook is formed on the panel side and the front glass is to be locked to the panel by the hook, the hook extends forward from the back of the panel so that the head of the hook does not protrude to the front of the front glass. To do this, a hook locking part must be provided inside the front of the front glass, and the fluorescent display tube becomes an obstacle because the base end of the hook enters the back of the panel. Could not be provided on the panel.

Therefore, conventionally, a double-sided tape has been used as a means for attaching an acrylic windshield to a panel. That is, as shown in FIG. 3A, black printing is applied to the edge portion of the front glass, and a double-sided tape is attached to the portion. Then, as shown in FIG. 3B, the front glass was attached to the panel with double-sided tape.

[0005]

According to the above-mentioned conventional windshield mounting method, black printing needs to be applied to the windshield to hide the double-sided tape, which increases the manufacturing cost. In addition, the need for a double-sided tape increases the number of components, and further involves a step of positioning and attaching the double-sided tape, which increases the number of assembly steps and significantly increases the overall manufacturing cost.

[0006] Further, once the double-sided tape is peeled off, the adhesive force when the double-sided tape is re-attached is lost, so that a new one must be used, so that maintenance is troublesome, the cost is increased, and the image of the product is also damaged. Had the disadvantage of being

[0007] The present invention has been made in view of the above points, and an object of the invention is to provide a windshield mounting mechanism capable of mounting a windshield on a panel without using a double-sided tape. It is in.

[0008]

According to the windshield mounting mechanism of the present invention, a windshield is formed in a box shape, and a hole is formed by providing a convex portion extending in the same plane at an upper or lower edge of the windshield. A projection extending perpendicularly from a surface of the edge portion, a projection or a hole formed on the panel to be fitted with the hole or the projection of the windshield, and a locking surface for abutting the edge outer surface of the windshield on the panel. A hook is provided that elastically bends in the horizontal direction, and the end face of the windshield and the panel surface regulate the position of the windshield in the panel. The position of the windshield outside the panel is regulated by fitting into the hole, and the downward position of the windshield is regulated by contact between the lower outer surface of the edge of the windshield and the panel positioning surface. By controlling the upward position of the windshield by engaging the upper outer surface of the edge of the windshield with the hook of the panel, the windshield is attached to the panel and the hook is displaced from the outside in this state. It is possible to make it.

[0009]

According to the windshield mounting mechanism of the present invention, the projection or hole of the front glass can be fitted to the hole or projection of the panel by moving the front glass from the upper side to the lower side. At this time, the hook provided on the panel bends backward so as not to hinder the movement of the windshield, but when the windshield and the panel are fitted, the hook returns to its original position due to elasticity and pulls out the windshield. Lock so that there is no.

[0010] Since the bending direction of the hook is the panel depth direction, the hook extends in the direction perpendicular to the panel depth direction, so that the depth dimension for mounting the panel is reduced, which is an obstacle for disposing the fluorescent display tube. No.

When removing the front glass from the panel,
It is sufficient to bend the hook of the panel backward and pull out the windshield upward.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A windshield mounting mechanism according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1A is a perspective view of the front glass used in the example as viewed from the rear,
FIG. 1B is a perspective view showing a cut-out portion of a front glass attachment portion of the panel in the embodiment.

The front glass 1 shown in FIG. 1A is formed of acrylic resin colored in wine color.
The front glass 1 is formed in a substantially box shape, and convex portions 1a, 1a are provided on an upper edge portion, and holes 1b, 1b are formed in the convex portions 1a, 1a.
1b is formed. Projections 1c, 1c are formed on the lower edge of the front glass 1.

The panel 2 shown in FIG. 1 (b) is formed by resin molding, and provided with projections 2a, 2a and holes 2c, 2c respectively fitted to the holes 1b, 1b and projections 1c, 1c of the front glass 1. Have been. Further, hooks 2b, 2b for locking the upper outer surface of the edge of the front glass 1 are provided, and positioning surfaces 2d, 2d for positioning the lower outer surface of the edge of the front glass 1 are formed around the holes 2c, 2c. .

The front glass 1 is attached to the panel 2 as shown in FIG. That is, by pushing the front glass 1 from above, the holes 1b, 1b and the projections 2a, 2
a, and the protrusions 1c, 1c and the holes 2c, 2c are fitted. At this time, the hooks 2b, 2b bend rearward, and thereafter return to their original positions by elasticity, and lock the upper outer surface of the edge of the front glass 1.

The position of the front glass 1 in the downward direction is restricted by the contact between the lower outer surface of the edge and the panel positioning surface 2d.
The abutment between the end surface of the edge and the panel surface regulates the position in the panel in the inward direction, and the abutment between holes 1b, 1b and protrusions 2a, 2a and the abutment between protrusions 1c, 1c and holes 2c, 2c. Regulates the outward position.

Since the hooks 2b, 2b are locked, they do not come off upward, and the front glass 1 does not come off the panel 1 unless the hooks 2b, 2b are bent backward.

A fluorescent display tube mounted on a printed circuit board is arranged inside the front glass 1. The protrusions 1a,
Since the projections 1a and the projections 1c, 1c are provided at the back of the edge, even if the front glass is translucent, it is difficult to see from the outside, and an excellent appearance can be obtained.

Although the embodiment is constructed as described above, the invention is not limited to this. For example, the effect of the invention can be obtained by changing the combination of the hole and the projection provided on the front glass and the panel.

[0020]

According to the windshield mounting mechanism of the present invention, since no double-sided tape is used, there is no need to apply black printing to the windshield, and the number of assembling steps is reduced and the manufacturing cost is reduced. Furthermore, the image of the product is improved because the double-sided tape is not bonded.
