Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an angle adjustment mechanism, and more particularly to an angle adjustment mechanism that adjusts the inclination angle of an accessory operation member such as a keyboard that is separated from the main body. It is something.

[Prior Art] For example, many electronic devices such as word processors and microcomputers are equipped with additional operating members such as keyboards that are separated from the main body.

Many conventional keyboards of this type are equipped with an angle adjustment means so that the operator can maintain a posture that is less tiring.

Most of this type of mechanism consists of an angle adjusting leg and its rotating shaft.

[Problems to be Solved by the Invention] However, with this type of conventional mechanism, the operability was extremely poor because the keyboard was turned over and the angle adjusting legs were rotated when operating the angle adjusting legs.

Additionally, some devices are provided with operating knobs and the like to improve operability, but in this case there is a problem in that the number of parts increases, which is a factor in increasing costs.

Means for Solving Problems c] In the present invention, in order to solve the above-mentioned problems, a
A rotary shaft is installed at a predetermined angle in the case of a device whose inclination angle with respect to the city must be adjusted, and the upper end of the rotary shaft faces the top of the case as a knob, and is placed on the + end of the rotary shaft. A structure with a bent part that touches the surface was adopted.

[Function] When the above structure is adopted, the knob part and the rotating shaft are integrated, and the knob part faces the top of the case, so the rotating shaft can be turned from the top of the case, making one rotation. When the shaft is rotated, the bent portion rotates, and the inclination angle of the device relative to the A-layer plane can be adjusted.

[Example] Hereinafter, the present invention will be described in detail based on an example shown in the drawings.

The figure explains one embodiment of the present invention, and shows a keyboard as an example of an additional operating member.

The keyboard body is composed of an upper case 1 and a lower case 2, and a recess 1a formed in a part of the upper case l.
A knob 3a of the angle adjusting leg 3 is facing. The angle adjusting leg 3 is sandwiched between the upper case 1 and the lower case 2.

The angle adjusting leg 3 has a rotating shaft 3b whose axis line is at an angle a with respect to the horizontal plane, and an operating knob 3a is provided at the upper end of the rotating shaft 3b. I'm going to face it.

Further, a bent portion 3f is formed at the tip of the rotating shaft 3b.

Flanges 3c and 3d are formed on the upper and lower sides of the rotating shaft 3b, and the lower flange 3d is connected to the rib lb of the upper case l.
and is rotatably held by the rib 2a of the lower case 2.

The upper flange 3C has multiple recesses 3 for click rotation.
e are provided, and a plurality of protrusions IC that fit into these four parts 3e are formed on the -F case side.

The flange 3C and the protrusion IC are made to have elasticity.

Since this embodiment is configured as described above, when the operating knob 3a is pinched and rotated, the bent portion 3f of the angle adjusting leg 3 changes from the horizontal state indicated by symbol A to the vertical state indicated by symbol B. By rotating the recess 3e and the protrusion I
The keyboard is temporarily fixed at multiple angles by a click mechanism consisting of C, and the inclination angle of the keyboard with respect to the desk surface can be changed.

Note that the weight of the keyboard itself and the force applied when hitting the keys are received by the ribs lb and 2a of the case below.
The click mechanism consisting of the recess 3e and the protrusion 1c will not come off.

Furthermore, since the angle adjustment legs 3 are provided at least on the left and right sides of the keyboard, the keyboard will not become unbalanced after the angle adjustment of the keyboard.

Furthermore, although the above-mentioned embodiment has been explained using a keyboard as an example, it can be widely applied to other devices that require adjustment of the angle relative to a desk surface, such as a calculator equipped with a liquid crystal display, etc. .

[Effects] As is clear from the above description, according to the present invention, the structure in which the angle adjustment leg and the operation knob are integrated is used, so the number of parts is reduced and the angle adjustment mechanism is simplified. It is possible to reduce costs.

Furthermore, since angle adjustment can be performed from the top side of the keyboard, etc., operability is greatly improved.

Claims (1)

[Claims] A rotating shaft is installed at a predetermined angle in the case of a device whose inclination angle relative to the mounting surface needs to be adjusted, and the upper end of the rotating shaft is used as a knob to face the upper side of the case, and the lower end of the rotating shaft is attached to the mounting surface. An angle adjustment mechanism characterized by having a bent portion in contact with.
