Description

[Detailed Description of the Invention] The present invention relates to an opening/closing lid device that is most suitable for application to, for example, various electronic devices.

For example, in electronic devices such as video tape recorders (VTRs), radio receivers, and television receivers, so-called sub-control panels, battery compartments, and the like are provided with opening/closing lids.

Among these opening/closing lids, especially those that are opened/closed by rotational movement, a locking means for holding the opening/closing lid in a closed state is provided between the opening/closing lid and the cabinet.

For example, as shown in Fig. 1 and Fig. 2, the opening/closing lid 1
A locking pawl 2 is slidably provided on the cabinet 3, and the locking pawl 2 engages with the inner surface of the cabinet 3 to hold the opening/closing lid 1 in a closed state.

When opening the opening/closing lid 1, the locking claw 2 is slid through the opening 4 provided on the front side of the opening/closing lid 1.
This releases the engagement.

However, in this conventional device, the opening 4 for operating the locking claw 2 was provided on the front side of the opening/closing lid 1, that is, on the front side of the cabinet 3, so it was not very desirable in terms of design.

Further, even if the opening/closing lid 1 is biased to the open state by a spring or the like, there is a drawback that the opening operation cannot be performed smoothly because the fingers or the like that slide the locking claw 2 get in the way.

Furthermore, since the opening/closing lid 1 is rotated after the locking claw 2 is slid, the operating feeling is not good.

There is also a known device in which a locking pawl is integrally provided at the tip of the opening/closing lid, and this locking pawl is elastically engaged with the inner surface of the cabinet to hold the opening/closing lid in a closed state.

However, even with such a device, a handle must be provided on the front side of the lid for pulling the lid to release the engagement.

Therefore, it is still not desirable in terms of design.

Also, the operation feeling is not good.

The present invention has been devised to overcome the above-mentioned drawbacks, and aims to provide an opening/closing lid device that is favorable in terms of design and has a smooth opening operation.

Hereinafter, an embodiment in which the present invention is applied to an opening/closing lid device for a sub-control panel of a VTR will be described with reference to FIGS. 3 to 5.

As shown in FIG. 3, the front side of the cabinet 7 of the VTR according to this embodiment is constituted by a control panel on which various operation buttons 8 and the like are arranged.

A sub-control panel 9 is provided at the lower end of the cabinet 7 below this control panel.

As shown in FIG. 4, this sub-control panel 9 is formed as four parts 10 in the cabinet 7, and inside thereof are arranged switches 11 for the recording time, automatic cue, audio monitor, etc.

Further, this sub-control panel 3 is provided with an opening/closing lid 12 having a cross-section shaped like a bow.

A pair of pivot joints 14 having a C-shaped cross section are integrally provided at the end of the lower surface 13 of the opening/closing lid 12, and are formed by a notch 16 in the lower surface 15 of the cabinet I/7. Shaft part 1
These pivot parts 14 are removably attached to 7.

The opening/closing lid 12 is rotatable around this shaft portion 17.

A slit 22 is formed in the center of the lower surface 15 of the cabinet 7, and a pair of pins 23 are provided inside the slit 22 facing each other.

Linear springs 24 are attached to these pins 23.

This linear spring 24 is inserted into an insertion hole 25 provided on the back side of the lower surface 13 of the opening/closing lid 12.
2 is biased to the open state.

As shown in FIGS. 4 and 5, on the upper wall portion 18 of the recess 10, a locking pawl 19 formed from synthetic resin or the like in a substantially S-shape is disposed approximately at the center thereof.

This locking pawl 19 is for elastically engaging with an engaged portion 20 provided at the tip of the opening/closing lid 12 to hold the opening/closing lid 12 in a closed state.

On the other hand, an operating member 21 for releasing the lock is provided on the inner surface 26 of the opening/closing lid 12, facing the locking claw 19.

This operating member 21 is inserted into an insertion hole 28 formed by an inner surface 26 of the opening/closing lid 12 and a back plate 27 fixed to the inner surface 26 facing the opening/closing lid 12, and is inserted along the inner surface 26 of the opening/closing lid 12. It is slidable in the vertical direction.

That is, each pair of elastic engagement portions 30 and locking protrusions 31 are integrally provided on the operating member 21, and these are arranged within four portions 32 provided on the side wall of the insertion hole 28.

The elastic engaging portion 30 is connected to the lower end wall portion 3 of the recess 32.
3 and the position where the locking protrusion 31 abuts the upper end wall 34 of the recess 32.
1 slides in the vertical direction along the inner surface 26 of the opening/closing lid 12.

Further, one end 21' which is the lower end of the operating member 21 is connected to the opening/closing lid 1.
It protrudes downward from an opening 29 provided in the bottom part 13 of 2.

Next, the operation of the opening/closing lid device configured as described above will be explained.

First, as shown by the solid line in FIG.
is engaged in.

The operating member 21 is lowered by its own weight, and one end 21' thereof protrudes downward from the opening 29 of the opening/closing lid 12 for a relatively long length.

In order to release the opening/closing lid 12, one end 21' of the operating member 21 protruding from the opening 29 is pushed upward with a finger or the like.

Then, the operating member 21 slides upward, and its upper end, the other end 21'', directly presses the locking pawl 19, removing the locking pawl 19 above the engaged part 20, and the above-mentioned Release the engagement.

Therefore, the opening/closing lid 12 is rotated in the direction of the arrow in the figure by the biasing force of the linear spring 24.

At this time, as shown by the chain line, the finger or the like that pressed the operating member 21 is located exactly in the direction of rotation of the opening/closing lid 12, and the rotation of the opening/closing lid 12 is appropriately braked by this finger or the like. .

Therefore, for example, when the operation member 21 is installed on the cabinet side, the lid moves suddenly and every time the opening operation is performed, a shock is generated, and the lid may break after being repeated many times. do not have.

In addition, when the operating member 21 is provided on the front side of the opening/closing lid as in the past, the distance that the fingers, etc. must move is inevitably large.
On the contrary, this finger etc. will get in the way of the opening operation, but as in this embodiment, one end 21' of the operating member 21
If it is placed on the lower surface 13 of 2, the moving distance of the fingers etc. will be greatly shortened, making the opening operation very smooth.

Although the present invention has been described above with reference to one embodiment, the above embodiment does not limit the present invention in any way, and various modifications can be made based on the technical idea of the present invention.

For example, in the embodiment described above, the engagement of the locking pawl 19 is released by sliding the operating member 21 in the vertical direction.
This may be rotatably attached to the inner surface 26 of the opening/closing lid 12, and the engagement may be released by rotating the operating member 21.

Further, the opening/closing lid device according to the present invention is not limited to the lower end of the cabinet, but can be installed at any end of the right, left, or upper end of the cabinet.

As explained above, in the opening/closing lid device according to the present invention, the opening/closing lid is rotatably provided at the end of the cabinet and has an L-shaped cross section, and the opening/closing lid is rotatably provided at the end of the cabinet. A locking claw provided on the side, a lock release operation member movable along the inner surface of the opening/closing lid to release the locking caused by the locking nail, and a locking release operation member movable along the inner surface of the opening/closing lid, and the opening/closing lid being opened. and a rotational fulcrum is provided at the end of the opening/closing lid forming the cross-shaped opening and closing lid, which is disposed on a side different from the front side of the cabinet, and One end of the operating member is provided so as to protrude from a side of the opening/closing lid that is in the shape of an inverted letter, which is different from the front side of the cabinet, and by operating this one end, the other end of the operating member engages the user. The locking claw is directly pressed to release the locking.

Therefore, in the opening/closing lid device of the present invention, one end, which is the operating end of the operating member, is disposed at a position that is not very conspicuous in appearance, resulting in a clean design.
