Description

[Detailed Description of the Invention] Technical Field The present invention relates to an improvement of the housing of a personal computer or the like, and in particular, the present invention relates to a small data input device in which almost one side of the housing is occupied by a keyboard.

BACKGROUND ART Conventionally, a casing of a personal computer or the like is provided with a keyboard on one side thereof as a data input device, on which many keys are arranged. This is because the computer part is extremely small, so the housing looks like a data input device consisting only of a keyboard.

On the other hand, such a small casing is usually used by being installed on the same desk together with other devices such as a floppy disk device, a printer, a cathode ray tube display device, and the like. At this time, the size of the desk is generally designed to have the minimum desk space on which only these devices can be placed, from the viewpoint of effective use of space. Furthermore, when using these devices, the user usually carries documents or tools to refer to when inputting and outputting data. In this case, there is not enough space on the desk to place these documents or tools. This is because the computer part is so small that it is combined with the data input device, and an independent space cannot be allocated to the data input device alone. Therefore, in the past, users of such small-sized computer systems were placed in an extremely difficult situation when operating them.

Disclosure of the invention The purpose of this invention is to expand the usable space of the user only during use when the input device of an electronic equipment system is small and does not give the user space. be.

The configuration of this proposal is that for a keyboard where multiple keys for inputting data occupy almost the entire surface of the housing, the lid body that is closed for dust-proofing and design purposes is always opened when in use. Focusing on that,
This housing has a keyboard with a plurality of keys on the top surface, a first engaging portion on the side surface, and a first engaging portion on one free end.
a lid body provided with a second engaging part that engages with the engaging part; one end is rotatably pivoted to the lid body so that both ends of the lid body are free ends; It has a bendable arm that is pivoted to the housing, and when the arm is bent, the lid covers the keyboard, and when the arm is extended, the lid is flipped over and takes a horizontal position. It is characterized in that the second engaging part is engaged with the first engaging part so as to be maintained.

Here, the lid in the present invention is turned over when the lid is opened from the state of covering the keyboard, and the surface that previously faced the keyboard is utilized as an enlarged plane during use.

As a result, according to the present invention, the expanded space can be created by simply opening the lid naturally without requiring the user to perform any special work to secure the expanded space.

BEST MODE FOR CARRYING OUT THE INVENTION FIG. 1 is a side view showing an embodiment of the invention.
FIG. 2 is a side view of the device shown in FIG. 1 in use.
Moreover, FIG. 3 is a perspective view of the main part showing an embodiment of the lid body control mechanism, which is the main part of the present invention.

In FIG. 1, 1 is a housing, 2 is a lid, 3 is an engaging part, 4 is a second engaging part, and 5 is a lid control mechanism. One side of the housing 1 is constituted by a keyboard 11 on which a plurality of keys 10 are arranged,
This keyboard 11 is covered with a lid 2. Further, as shown in FIG. 2, on the side wall 12 of the casing 1, an arm holding portion 13, which forms part of a lid control mechanism to be described later, is formed to protrude when the lid 2 is in use with the lid opened. be done. This is also formed on the other side wall (not shown) opposite side wall 12. One of the other side walls 14 and 15 orthogonal to this side wall 12 is provided with a first engaging portion 3 which will be described later.
is formed.

The lid body 2 has a pair of legs 22 and 23 that protrude from the back surface 21 side facing the keyboard 11, and the space formed by the pair of legs 22 and 23 accommodates a plurality of keys 10 when the lid is closed. wrap around. Further, the above-mentioned second engaging portion 4 is formed at one end of the lid 2, for example, the end on the near side of the user. This second
The engaging portion 4 is constituted by a locking hook 41 protruding from the back surface 21. This second engaging portion 4 engages with the first engaging portion 3 in the usage state shown in FIG. 2.
Therefore, the first engaging portion 3 is constituted by the engaging hook piece 31 for engaging with the locking hook piece 41 of the locking portion 4 . Further, as shown in FIG. 2, the engaging hook piece 31 is formed to protrude toward the bottom surface of the housing 1 so as to maintain the lid body 2 in a horizontal position during use.

The lid control mechanism 5 includes two connecting rods 51 and 52 connected by a bearing structure as shown in FIG. 3, which will be described later.
and the arm holding portion 13 described above. Note that the arm is constituted by connecting rods 51 and 52. One end of this arm is rotatably fixed to the lid body 2 by a shaft 53, as shown in FIG.
The other end is fixed to the side wall 12 of the housing 1 by a shaft 54 . Such an arm is provided on the other side wall opposite to the side wall 12 in exactly the same manner. In addition, this arm is bent into two connecting rods 51 and 52 at the shaft bearing part 50 when the lid is closed as shown in FIG. 1, and into two connecting rods 51 and 52 when the lid is opened as shown in FIG. 52 is straight-stretched. Therefore, the shaft bearing structure of the two connecting rods 51 and 52 is such that it can be bent only in one direction from the straightly extended state. FIG. 3 shows a specific example of such a bearing structure, in which the two connecting rods 51 and 52 can be bent only in one direction as indicated by arrows A and B, respectively. Shaft bearing part 50 in this example
The tips of two connecting rods 51 and 52 are rotatably connected by a shaft 501. At both ends of the connecting rods 51 and 52, when both are overlapped for connection,
The opposing surfaces 521 and 522 of one connecting rod 52 are the opposing surfaces 511 and 522 of the other connecting rod 51, respectively.
512 so that the respective surfaces coincide with each other.
20,510 are formed. This stepped portion 510,5
One corner of the tip of 20, that is, the connecting rod 51,
52 has a radius 513 at the corner on the bending direction side,
523 is provided. Moreover, the other corner is each broken part 52 of one connecting rod 52 and the other connecting rod 51.
0,510 so that they abut each other. Therefore, both connecting rods 51 and 52 are indicated by arrows A,
It cannot be bent in the opposite direction. Connecting rod 51,
In order to sufficiently withstand the force in this direction applied to each of the connecting rods 52, in this embodiment
A stopper 524 is provided at the other corner of 2.
This stopper 524 may be provided at each corner of both connecting rods 51, 52, or may be omitted. In the bearing part 50 having such a structure, when the connecting rods 51 and 52 are bent in the directions of arrows A and B, the radiuses 513 and 523 of one corner come into sliding contact with the step parts 510 and 520. Furthermore, when attempting to bend the connecting rods 51, 52 in the opposite direction, the other corner comes into contact with the stepped portions 510, 520, and the bending operation is stopped with both connecting rods 51, 52 extending in a straight line. I am made to do so.

The apparatus according to the present invention having the above-mentioned structure goes from a closed state as shown in FIG. 1 to an opening operation of the lid body 2 as shown in FIG. 4, and then reaches a usage state as shown in FIG. 2. Further, when transitioning from the use state to the closed state, this order is reversed. The operation of the apparatus according to the present invention will be explained below with reference to FIG.

First, the lid body 2 is moved in the direction of arrow C shown in FIG. 1, and enters the state shown in FIG. 4A. At this time,
The second engaging portion 4 of the lid 2 is located at a position lower than the first engaging portion 3 of the housing 1 indicated by arrow D in FIG. 4A.
Moved to the right in the illustration. At this time, if this movement is not performed and the lid body 2 is rotated about the shaft 53, the state shown in FIG. 4B will be obtained. That is, the second
The engaging portion 4 is located to the left in the figure from the above-mentioned arrow D, and above the arrow H indicating the height position of the first engaging portion 3 in the figure. Therefore, when the arm is rotated downward in the figure about the shaft 54 from this state, the second engaging portion 4 collides with the end of the casing 1 where the first engaging portion 3 is disposed. From this, the lid body 2
The second engaging portion 4 is first moved to the state shown in FIG. 4A. Then, the connecting rods 51 and 52 are pushed and extended in the direction of the arrow in the figure to form an arm.
The lid body 2 moves to the state shown in FIG. 4C. As already mentioned, the straight-extended arm does not bend due to the bearing structure shown in FIG. 3 even if a force is applied in the direction of the arrow in FIG. 4A. Therefore, the force is the fourth
The lid body 2 and the arm are rotated about the shaft 54 in the direction shown by the arrow G in FIG. As a result, the arm and the lid 2 move to the state shown in FIG. 4D. In this case, the arm abuts and is placed on the arm holding portion 13 provided on the side wall 12 of the housing 1, and is
Rotation in the direction of arrow G is stopped. Then, the lid body 2 is rotated about the shaft 53 in the direction of arrow 1 in FIG. 4D, and the engagement between the second engaging portion 4 and the first engaging portion 3 is completed. As a result, the lid body 2 is in the usage state shown in FIG. 2. The above-mentioned movements of each part are performed during the operation of opening the lid body 2. Also, each part performs the reverse operation when closing the lid. Therefore, according to the device of this embodiment, a usable space is created in front of the user as soon as the lid 2 is opened.
Moreover, the back surface 21 of the lid body 2, which is formed as a usable space, is supported by the combined force of the arm, the arm holding part 13, the first engaging part 3, the second engaging part 4, and the shaft bearing part 50. This makes it strong and stable. Also, legs 22 formed to wrap around the key 10,
23 is also utilized as an anti-slip device for objects placed on the usage surface when in use.

In the embodiment device described above, an example has been given in which the lid body 2 is opened in front of the user, but the present invention is not limited to this.
The lid may be opened to the rear. Further, the direction in which the arm is bent may be opposite to that of the embodiment device described above.
