Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a keyboard device, which is a type of information input device used in electronic devices such as personal computers and word processors, and particularly relates to a keyboard device that is a type of information input device used in electronic devices such as personal computers and word processors. The present invention relates to a keyboard device for electronic equipment.

[Summary of disclosure]

This specification and the drawings disclose a technique for a keyboard device that can change the angle of the keyboard surface while in use without turning the keyboard device over.

[Conventional technology]

For electronic devices such as personal computers and word processors, the keyboard is separated from the main body for ease of use as the main body becomes larger, allowing the user to operate the keyboard device at the desired position. In this case, there are various methods for transmitting key signals from the keyboard device to the main unit, such as wired methods using cables and wireless methods using infrared rays, etc., and the user can operate the keyboard device by placing it in a desired position within the transmission range. Also,
Keyboard devices often have rotatable legs attached to the bottom surface of the keyboard so that the angle of the keyboard surface can be changed according to the user's preference.

[Problem that the invention seeks to solve]

However, the legs attached to this type of keyboard device are attached to the bottom of the device, so if the user attempts to rotate the legs to change the angle of the keyboard surface, the user must first turn the device upside down. Naturally, this type of keyboard device was extremely difficult to use due to its size and heavy edges.

[Means for solving problems]

In order to solve these problems, the present invention includes legs that are rotatable around an axis provided on the side surface of the keyboard so that the angle of the keyboard surface of the keyboard can be changed while in use. , and a protrusion for imparting rotational motion to the leg.

[For production]

If you hang your finger on the protruding part that gives rotational motion to the legs, which are rotatable around an axis provided on the side of the keyboard, while the keyboard is in use, the legs will rotate and the legs will rotate. The angle of the keyboard surface changes as the effective length increases.

[Example] Hereinafter, details of the present invention will be explained by showing one example. FIG. 1 is an exploded perspective view of a keyboard device according to the present invention, and FIG. 2 is a side view of the device.

Also, Fig. 3 is a sectional view of the main part of the leg structure, Fig. 4 is an external view of the leg, Fig. 5 is a plan view of the shaft of the lower case, Fig. 6 is the top,
FIG. 7 is a front view of the shaft portion when the lower case is put together. First, to explain the overall structure, l is an upper case that constitutes a part of the housing of the keyboard device, 2 is a lower case, and 3 is a lower case.
are key switch 3a, key top 3b, key chassis 3
c.

This is a keyboard unit in which a keyboard printed board 3d and the like are integrated, and the keyboard unit is held between upper and lower cases. Reference numeral 4 denotes a leg that is rotatably attached to the shaft of the upper case or the lower case, but in this embodiment, the leg 0, which is attached to the shaft 2a of the lower case, is a leg that is attached to the shaft of the lower case. By fitting the bearing parts 4a of the parts, one each of both side parts can be attached to the lower case.

A protrusion 4b on which a finger or the like can be hung is integrally provided on the leg in order to provide rotational motion, and a keyboard device is placed on the opposite side of the protrusion from the center of rotation of the leg. A support portion 4C that is in contact with the surface is integrally provided. Therefore, as shown in FIG. 2, if the protrusion of the leg is rotated with a finger or the like, the support part rotates by a certain angle in response to the rotation, so that the angle of the keyboard surface can be changed. To further explain the structure of the legs in detail, as shown in Fig. 1, there is a shaft part integrated with the lower case on the side part of the lower case, and as shown in Fig. 3, there is a shaft part on the side part of the lower case. The leg portion is integrally provided with a bearing portion that freely fits coaxially with the shaft portion. The bearing portion has a first groove portion 4d at a predetermined position.
and a second groove 4e, and a convex portion 2b having a shape to engage with the groove is provided on the shaft portion. The positional relationship between the first and second grooves and the protrusion is such that in the initial state, the first groove and the protrusion are engaged, and when the leg is rotated to a predetermined angle, the second groove and the protrusion are engaged. The relationship is such that the parts are locked. Therefore, if the lengths of the first and second grooves are appropriately determined, the portion sandwiched between these grooves becomes an elastic cantilever, and while the convex portion moves from the first groove to the second groove, Since the bearing portion 4f between the grooves is elastically deformed, the convex portion can be moved easily, and a snap action can be obtained at the moment the convex portion engages with the second groove portion. The same holds true when the convex portion moves from the second groove to the first groove. In addition, since only two grooves are provided in this embodiment, the angle of the keyboard surface is also two.
Although it can only be changed in the same direction, it is also possible to increase the types of adjustment angles by increasing the number of grooves.

Next, a method for preventing the legs from falling off the main body will be explained. As mentioned above, since the legs are inserted into the shaft of the lower case through the external sash, they will fall off if they are moved in the opposite direction. , first and second locking parts 4g for the lower case,
4 hours are provided. At the same time that the bearing part of the leg is inserted into the shaft part of the lower case, the first locking part is inserted into the bag provided in the lower case through the opening 2C provided in the lower case shown in FIGS. 5 and 6. The second locking part jumps into the bag groove 1a provided in the first case when the first case is placed over the lower case after the leg part is inserted into the shaft part of the lower case. It has become.

In this way, after inserting the legs into the shaft of the lower case, by covering the upper case with the lower case, the locking parts provided on the legs engage with the bag grooves of the upper and lower cases, so the legs The legs will not fall off from the upper and lower cases even if a force is applied in the opposite direction to the insertion. 0 After rotating the legs,
The second locking portion jumps into the bag groove 1b of the upper case, and the second locking portion jumps into the bag groove 2e of the lower case.

〔effect〕

As is clear from the above description, in the keyboard device having the leg structure according to the present invention, unlike conventional keyboard devices, there is no need to turn over the device body each time to rotate the legs. The legs can be rotated and the angle of the keyboard surface can be changed while the keyboard is in its original state, making it extremely easy to use, and since only one part is required for the legs, a rotatable leg can be obtained at a low cost. It has an excellent effect. In addition, if an elastic piece that causes a snap action is provided on the lower case side, as seen in conventional leg structures,
If the elastic piece is damaged due to repeated fatigue of the elastic piece, the entire lower case must be replaced, but with the leg structure of the present invention, only the leg needs to be replaced, which is advantageous in terms of maintenance. has.
