Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a decorative frame attachment device.

(B) Prior Art Decorative frames made of synthetic resin, such as those in the cassette insertion slot of front-loading video tape recorders (VTRs), are often fixed by welding. Examples are shown in Figure 1 A and B. A front panel 2 includes a decorative panel and a decorative frame for a cassette insertion slot integrated with a front panel base 1.
is attached by welding the boss 2a of the front plate.

For this reason, a welding jig is required, making the installation process complicated. Another disadvantage is that if the front plate is damaged, it is difficult to remove because it is welded.

(c) Purpose of the invention The present invention has been devised in view of the above points, and its purpose is to provide a mounting device for a decorative frame that is easy to install and does not come off accidentally.

(d) Structure of the invention In this invention, a decorative frame made of synthetic resin is provided with a key-shaped piece and a claw piece to be engaged with the panel side.
The key-shaped pieces are flexible and are provided on two opposing sides of the decorative frame, and their openings are aligned in the same direction. At least one pair of the hook-shaped pieces are provided on opposite sides. The claw pieces are provided on each of the remaining opposing sides, but the amount of protrusion of the claw piece in the direction of the opening of the hook-shaped piece is larger than the amount of protrusion of the other piece. The panel to which the decorative frame is attached has an opening into which the decorative frame is fitted and a protrusion that engages with the key-shaped piece.

(e) Examples Embodiments of the present invention will be described below with reference to the drawings.

The embodiment described below relates to a decorative frame in a front loading cassette insertion slot.

FIG. 2 is a perspective view showing a part of the panel and a decorative frame. The panel 3 has an opening 3a for inserting a cassette.
is provided. 4 is a decorative frame. Decorative frame 4
is a rectangular frame that is long in the lateral direction and corresponds to the opening. Since this decorative frame is made of synthetic resin and has a rectangular shape, it is easily bent in the direction of arrow F. Means for engaging with the opening 3a are provided on the four sides of the decorative frame 4, and corresponding means are also provided on the opening 3a side.

On the long side 4a of the decorative frame 4 are two key-shaped pieces 5,
5 and a protrusion 6 are provided. Opposing long side 4a
A hook-shaped piece and a protrusion are similarly provided on the top.
A claw piece 7 is provided on the short side 4b, and a claw piece 8 is similarly provided on the opposite short side 4b although it is not visible in the figure.

FIG. 3 shows a back view (a), a side view (b), and a bottom view (c) of the decorative frame 4, showing the shape of the entire decorative frame. As you can clearly see from the side view, the decorative frame 4 is located at the front part 4c.
It can be considered that the rear frame and rear frame 4d are integrated. The protrusion 6 is formed by extending the long side of the front portion 4c in the direction of the short side. When the decorative frame is attached, the front part 4c is exposed from the panel 3. The claws 7 and 8 on the short sides are set to protrude beyond the front frame 4c, and the amount of protrusion differs on the left and right sides as shown in FIG. 3A. This is related to the method of attaching the decorative frame 4.

The directions of the openings 5a of the hook-shaped pieces 5 are the same for all four. This is also related to the method of attaching the decorative frame 4. The protrusion amount of the claw piece 7 on the side toward the opening 5a is larger. The key-shaped piece is provided on the rear frame 4d and is located on the back side of the panel 3 after installation. The claw pieces 7 and 8 are also located on the back side of the panel 3 and come into contact with the back side of the panel 3. The reason why the protrusion 6 is discontinuous at the hook-shaped piece 5 is due to molding reasons.

The edge of the opening 3a in the panel 3 is constituted by a double frame. They are an outer frame 9 connected to the front surface of the panel and an inner frame 10 connected to the back surface. The shape of the outer frame 9 is such that the front frame 4c of the decorative frame 4 can fit therein. A rear frame 4d of the decorative frame 4 can be fitted into the inner frame 10. Since it is too narrow to insert the key-shaped piece 5, it is necessary to bend the decorative frame 4 during installation. The inner frame 10 has cutouts 10 for the claw pieces 7 and 8.
There are a and 10b. Inner frame 1 when installing decorative frame 4
0 and the protrusion 5 come into contact with each other to determine the position in the front-rear direction.

Figure 4 shows the back side of a part of the panel.
' side sectional view B, -' side sectional view C. A protrusion 11 with which the key-shaped piece 5 engages is provided on the back surface of the panel. The recess 12 adjacent to the protrusion 11 corresponds to the extended portion 9a of the outer frame on the front side of the panel 3. This extended portion 9a fits into the discontinuous portion of the protrusion 6. The notches 10a and 10b of the inner frame 10 on the back surface of the panel are the places where the claw pieces 7 and 8 of the decorative frame 4 fit, and the claw pieces 7 and 8 are adapted to abut against the outer frame 10.

When the decorative frame 4 is attached to the panel 3, the fifth
As shown in the perspective view of the figure. In this state, the opening 13a that fits into the front frame 4c of the decorative frame 4
A decorative board 13 (with adhesive means such as double-sided adhesive tape or adhesive on the back side) is fixed to the front surface of the panel to hide the protrusion 5 and the extension 9a. The decorative board 13 is also provided with windows and the like for various other display means.

The decorative frame 4 is attached to the panel 3 by utilizing the flexibility of the long sides of the decorative frame 4. When installing, first, the decorative frame 4 is placed on the panel 3 so that the protrusions 5 and the inner frame 10 are in contact with each other on the claw piece 7 side of the decorative frame 4 (the side with the larger protrusion). In other words, the decorative frame is first diagonal as shown by arrow C with respect to the panel.
In this state, and before the claw piece 7 is fitted into the notch 10a, a force in the direction of arrow F is applied to bend the long sides 4a, 4a, and the key-shaped piece 5 is inserted into the back side of the panel inner frame 10. . At this time, the inner frame 10 is
and a key-shaped piece 5.

Then, when the decorative frame 4 is slid so that the claw pieces 7 fit into the notches 10a, the key-shaped pieces 5 and the protrusions 11
will become engaged and cannot be slid any further. Therefore, the front frame 4c on the claw piece 8 side
Press the tab against the panel side and insert the tab piece 8 into the notch 10b.
Insert into. This completes the attachment of the decorative frame 4 to the panel 3.

In the attached state, the decorative frame is not easily removed due to the engagement between the key-shaped piece 5 and the protrusion 11 and the engagement between the claw pieces 7 and 8 and the outer frame 9. Furthermore, by attaching a decorative board 13 to the panel, the appearance is improved and the fixation of the decorative frame 4 is strengthened.

When removing the decorative frame 4 from the panel 3, it is sufficient to reverse the installation process. That is, the claw piece 8 is removed by pushing the decorative frame 4 from the back side of the panel, and is slid in the opposite direction until the hook-shaped piece 5 and the projection 11 are disengaged. Then, force is applied to the long sides of the decorative frame to bend it, and the key-shaped piece 5 is taken out from the back side of the panel.

(f) Effects of the invention As described above, according to the invention, it is possible to realize a decorative frame mounting device that does not require welding work and is easy to install and remove.
