Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Technical Field] The present invention relates to a hinged lid structure suitable for installation in cases of office automation equipment, various electronic equipment, and the like.

[Conventional technology]

Printers, fax machines, copiers, video cameras.

An opening for replacing consumables, adjusting switches, or performing maintenance and inspection is formed in the main body case of OA equipment such as keys, electronic equipment, etc., and this opening is usually closed with a lid structure.

Various types of this lid structure are employed, and one of them is one in which the lid member is pivotally supported at the edge of the opening via a hinge so as to be openable and closable.

However, with this type of conventional hinged lid structure,
Since a handle or four parts are required for opening and closing, the surface of the case (main body) is uneven even when closed, creating problems in appearance and ease of handling.

In addition, it is necessary to have the ability to reliably hold the lid in the closed position and maintain it in the open state, as well as the ability to open and close the lid easily and reliably.However, with conventional lid structures, it is difficult to achieve these functions. had a complex structure and required extra space.

〔the purpose〕

An object of the present invention is to provide a hinged lid structure that can solve the problems of the prior art, has a simple external structure, and has excellent operability.

[Means to achieve the purpose]

In the present invention, a lid member is attached to a main body so as to be openable and closable via a hinge movable along a long hole, and a predetermined opening angle of the lid member is set as a neutral point between the lid member and the main body in a closing direction. The above object is achieved by a configuration that includes a spring that biases the opening direction and a hook means that connects the two in the closed position.

〔Example〕

The present invention will be specifically described below with reference to the drawings.

FIG. 1 is a perspective view showing the lid structure in an open state according to an embodiment of the present invention, FIG. 2 is a perspective view showing the lid structure in FIG. 1 in a closed state, and FIGS. 3 and 4 are as shown in FIG. FIG. 3 is a cross-sectional view taken along line m-■ and line TV-rV in the figure.

In FIG. 1, an opening 2 is formed in the side surface of a main body or case 1, and a lid member 4 is attached so as to be openable and closable via a hinge 3 provided at the lower edge of the opening.

As shown in FIG. 3, the hinge 3 is slidably fitted into a long hole (long hole in the vertical direction) 5 formed on the main body 1 side, and is movable in the vertical direction together with the lid member 4. It consists of

As shown in FIGS. 1 and 3, a spring (a tension spring in the illustrated example) 6 is stretched between the lid member 4 and the main body l.

As shown in FIG. 3, the spring 6 is stretched so as to bias the lid member 4 in the closing direction and the opening direction with a predetermined opening angle θ of the lid member 4 as a neutral point. That is,
When the opening angle is less than θ, it is biased in the closing direction, and when the opening angle exceeds θ, it is biased in the opening direction, thereby facilitating opening and closing operations.

The lid member 4 is provided on the side of the main body 1 - 7 (Fig. 1)
1, the opening 2 is held in the open position shown in FIG.

FIG. 2 is a perspective view of the lid structure when the lid is closed.

When closing the lid member 4, the cough cup member is rotated (lifted) clockwise in FIG. 3 around the hinge 3, and when the opening angle becomes smaller than the neutral point θ, the lid member 4 is closed by the spring 6 A rotational force in the direction is applied.

As shown in FIGS. 1, 3, and 4, a hook 8 is provided at the tip of the lid member 4, and a window 9 is formed at a position corresponding to the hook 8 on the main body 1. ing.

When the lid member 4 rotates in the closing direction, the hook 8 is first stopped in a state where it abuts against the lower edge of the window 9 (the edge of the three hinges). At this time, if you press the top of the lid member 4,
While the slope 8A (FIG. 3) of the hook 8 slides on the lower edge of the window 9, the entire lid member 4 moves upward along the elongated hole 5. Therefore, the hook 8 enters into the window 9, and then the spring force of the spring 6 (in the example shown, gravity can also be used) causes the lid member to
is lowered again and set in the home position (closed position) as shown in FIG.

A slope spring 10 is mounted on the back side of the window 9, that is, in front of the closed position of the hook 8, as shown in FIGS. 3 and 4.

This slope spring 10 is for operating a microswitch 11 that detects that the lid is closed, and when the lid member 4 is set in the closed position (FIGS. 3 and 4), the hook 8 is activated.
The tip of the cedar plate spring 10 hits the cedar plate spring 10, and the cedar plate spring 10 is displaced, and the tip of the cedar plate spring 10 hits the micro switch 11 as shown in FIG.
By pressing 1, it is possible to turn the closing of the lid into a signal.

When opening the lid, by pushing the lower end of the lid member 4 upward, the hook 8 is pushed out of the window 9 by the reaction force of the leaf spring 10. In this state, the upper end of the lid member 4 is easily touched by the fingers, so that the lid can be easily opened by rotating the lid member counterclockwise in FIG. 3 with the fingers.

Further, as shown in FIGS. 1 to 4, a recess 12 corresponding to the shape of the lid member 4 is formed around the opening 2 of the main body 1, and when the lid is closed, the lid member 4 is configured so that the surface of the main body 1 substantially coincides with the surface of the main body 1.

According to the embodiments described above, the following effects were obtained.

(1) It can be opened and closed easily without the need for handles or recesses for opening and closing operations. Therefore, the surface of the lid can be freely designed to match the surface of the main body, which improves aesthetics and operability. An excellent lid structure was obtained.

ii) Since the hinge 3, which is movable along the elongated hole 5, and the spring 6, which has a neutral point at the position of the predetermined opening degree θ, are used together, the opening/closing operation is facilitated and the opening and closing positions are securely held. Uru lid structure (4).

(iii) Furthermore, in addition to the configuration in (ii) above, a coupling means consisting of a hook 8 and a window 9 is provided.

The lid member 4 can now be held in the closed position more reliably without impairing the ability to open and close the lid member 4.

(iv) Since the closed state detection means consisting of the leaf spring lO and the microsinch 11 can be activated using the hook 8, etc., this type of sensor can be easily mounted.

In the illustrated embodiment, the lid structure is provided on the vertical surface of the main body l and is opened from the upper end, but the present invention is capable of providing a hinged opening/closing lid on a horizontal surface, an inclined surface, or even a bent or curved surface. The same can be applied to the case where the hinge is provided, and the position of the hinge can be selected in any of the upper, lower, left, and right positions.

〔effect〕

As is clear from the above description, the present invention provides a hinged lid structure that is simple in appearance and structure and has excellent operability.
