Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to a support device for a cassette lid in an electric device such as a VTR (magnetic recording/reproducing device).

<Prior Art> A conventional cassette lid support device is constructed as shown in FIG. 6, an exploded perspective view, and FIG. 7, a schematic sectional view of main parts in an assembled state.

That is, a first pin 2 is implanted in the first frame 1, and this first pin 2 is attached to the cassette lid 3.
is pivotally fitted into a cylindrical hole 3a at one end of the
A shaft portion 4a of a holding pin 4 is fitted into the cylindrical hole 3b at the other end of the cassette lid 3, so that the cassette lid 3 is held swingably. The holding pin 4 is fitted into the C-shaped groove 5b and the hole 5a of the bent portion 5d of the second frame 5, and is biased by the leaf spring 6 in the direction of arrow A in FIG. Note that one end 6a of the leaf spring 6 is connected to the holding pin, and the other end is connected to the hole 5c of the second frame 5.
is engaged with.

By pulling the holding pin 4 in the direction opposite to the arrow A, the cylindrical hole 3b of the cassette lid 3 and the shaft portion 4a of the holding pin are separated, thereby removing the cassette lid 3.
It is also possible to remove it.

However, in this conventional support device, the second frame 5
The disadvantage is that space for the bent portion 5d and space for moving the holding pin 4 must be taken, and the number of parts is large.

<Purpose> The object of the present invention is to eliminate the above-mentioned drawbacks and provide a support device for a cassette lid that can be attached and detached using less space and a smaller number of parts.

<Examples> Examples of the present invention will be shown below. First, a first embodiment will be explained with reference to FIGS. 1, 2, and 3. Figure 1 is a perspective view showing the assembled state of the cassette lid support device, Figure 2 is an exploded perspective view of the same, and Figures 3a and 3b are sectional views of the fitting portion of the first frame and the cassette lid. In this support device, a cassette lid 13 is swingably supported between a first frame 11 and a second frame 15 which are spaced apart from each other. Hole 1
A first pin 12 having a diameter equal to the inner diameter of 3a is provided,
A conical hole 13a is provided at one end of the cassette lid 13, and the conical hole 13a and the first pin 12 are fitted into each other.The second frame 15 is provided with a U-shaped groove 15b, and the cassette lid 13 is provided with a U-shaped groove 15b. A second pin 13b is provided at the other end of the U-shaped groove 15b.
and the second pin 13b are directly fitted into each other, and the second frame 15 and the other end of the cassette lid 13 are removably engaged with a retaining piece 14 for the second pin 13b.

All of the above parts are made of synthetic resin.

A bearing hole 14b into which the second pin 13b is inserted is formed in the retaining piece 14, and a claw 14a that engages with an engagement hole 15a formed in the second frame 15 is provided in the elastic deformation portion 14c. ing.

To explain the assembly procedure, after fitting the second pin 13b of the cassette lid 13 into the bearing hole 14b of the retaining piece 14, as shown in FIG. 13 conical holes 13
a, and then move the cassette lid 13 down in the direction of arrow B centering on the first pin 12 as shown in Figure 1.
The second pin 13b is inserted into the U-shaped groove 15 of the second frame 15.
b, and is further moved downward to engage the claw 14a in the engagement hole 15a of the second frame 15 by deforming the elastic deformation portion 14c.

In the assembled state, the second pin 13b is in the U-shaped groove 1.
5b, and furthermore, the claw 14a is attached to the second frame 1.
Since it is engaged with the engagement hole 15a of No. 5, it is held securely.

In the first embodiment, the second pin 13b is inserted into the U-shaped groove 15b of the second frame 15, but as in the second embodiment shown in FIG. On the 13 side, there is a circular hole 14 for the second pin 13b.
d, and a U-shaped groove 15b on the second frame 15 side.
It is also possible to provide a structure in which the second frame 15 and the second pin 13b do not come into direct contact (indirectly fit together) by providing an engagement pin 14e that engages with the second frame 15 and the second pin 13b.

Next, a third embodiment of the present invention will be described based on FIGS. 5a and 5b. In the support device for swingably supporting the cassette lid 13, the first frame 11
is provided with a conical hole 13a, and a first pin 12 is provided at one end of the cassette lid 13, and the conical hole 13a and the first pin 12 are fitted together, and the second frame 15 includes: A second pin 13b is provided, and the second frame 15 is provided with a second pin 13b.
b is provided so that the U-shaped groove 15b and the second pin 13b are directly fitted into each other, and the second frame 15
and the other end of the cassette lid 13 are removably engaged with a retaining piece 14 for the second pin 13b.

The above embodiment provides a support device that reliably holds the cassette lid 13 with a small space and a small number of parts.

Also, when removing the cassette lid 13, use the claw 14.
By removing the pin a from the notch 15a, it can be easily removed in a direction perpendicular to the second pin 13b. Furthermore, the cassette lid 13 is attached to the first frame 11 by the urging force of the elastically deformable portion 14c of the retaining piece 14.
Since the cassette lid 13 can be lightly pressed against the side, it is possible to eliminate rattling of the cassette lid 13.

<Effects> As is clear from the above description, the present invention provides a support device that swingably supports a cassette lid between a first frame and a second frame spaced apart from each other. One end of the cassette lid and the first frame are provided with one of a conical hole and a first pin equal to the inner diameter of the conical hole; The other of the frame is provided with the other of the conical hole and the first pin, and the conical hole and the first pin are fitted together, and the other end of the cassette lid and the second frame are fitted with each other. One of the U-shaped groove and the second pin is provided on one side, and the other of the U-shaped groove and the second pin is provided on the other end of the cassette lid and the second frame. The U-shaped groove and the second pin are directly or indirectly fitted into each other, and a retaining piece having a bearing hole into which the second pin is inserted is detachably attached between the second frame and the other end of the cassette lid. The retaining piece is provided with a claw for fixing the retaining piece in order to prevent the second pin from slipping out of the U-shaped groove, and the claw is provided on the other end of the cassette lid or on the second frame. The retaining piece is provided with an elastic deformable portion that is engaged with the engaging hole and presses the cassette lid in the direction of the first frame.

Therefore, by fitting the first pin into the conical hole at one end of the cassette lid, the cassette lid can be tilted freely with respect to the first frame, and the cassette lid can be rotated around the one end. Therefore, the second pin at the other end can be easily inserted into the U-shaped groove, and the cassette lid can be assembled as long as the width of the cassette lid is sufficient. Moreover, since the pin supporting the cassette lid and the U-shaped groove that fits into the pin are respectively provided on the cassette lid or the frame, no other parts for supporting the cassette lid are required.

Therefore, there is no need for a space for the bent portion of the frame and a space for moving the holding pin as in the prior art, so it is possible to obtain a support device that reliably holds the cassette lid with less space and fewer parts.

Further, since the elastically deformable portion of the retaining piece lightly presses the cassette lid toward the first frame, it is possible to eliminate wobbling of the cassette lid.

Moreover, when removing the cassette lid, the fixation of the retaining piece is released by disengaging the claw of the retaining piece from the engagement hole, and the second pin can come out from the U-shaped groove, and the cassette lid is centered on one end. Since it can be rotated freely, it can be easily removed.

In addition, when using electrical equipment, the claws will not come out of the engagement holes even if excessive force is applied to the cassette lid, so the retaining piece has the excellent effect of preventing it from coming off the cassette lid or second frame. .
