[0001]

[Technical field to which the invention belongs]

 The present invention relates to a type of keyboard key balancing device, and in particular, equilibrium rods having a substantially C shape in plan view are installed on the front and rear of the keyboard key top so that their openings face each other. The two balancing rods are crossed in side view, and both sides of the two balancing rods are pivotally connected to the base and key top of the keyboard, respectively. The present invention relates to a device which transmits a force to a key top regardless of the angle at which the top is pressed, so that a reliable pressing can be achieved.

[0002]

[Prior art]

 Generally, most of the keys on the keyboard, especially the space key, are elongated, and therefore, a balancing device is provided in the space key. As shown in FIG. 4, in this balancing device, a balancing rod 71 is pivotally connected to one side of the space key 7, one side of the balancing rod 71 is pivotally connected to the front side of the space key 7, and the other side is inclined. When the space key 7 is pressed and one side where the space key 7 and the balance rod 71 are pivoted is pressed when the space key 7 is pressed, the pressing force is completely Is pressed to achieve a reliable pressing operation, but if one side of the space key 7 that is not pivotally connected to the balancing rod 71 is pressed, the pressing force is not completely transmitted, and the reliable pressing operation is performed. In particular, in the case of light and thin notebook computers, the thickness of the keytops is extremely thin, so that it is easy to cause a situation where reliable pressing cannot be performed.

The keyboard according to claim 1, wherein the other ends of the support rods (22) on both sides are further bent inward to form a second pivot rod (23) parallel to the first pivot rod (21). It is a key balancing device.

The invention according to claim 4 is the keyboard balancing device according to claim 1, characterized in that the pivoting portion 31 provided on the upper surface of the base 3 is formed as a sliding groove.

The invention according to claim 5 is the keyboard balancing device according to claim 1, wherein the pivotal connection portion 11 provided on the inner wall of the key top 1 is a fixing groove.

The device according to claim 1, wherein the left and right sides of the two balancing rods (2, 2 ') are movably pivotally connected to each other. It is.

[0010]

[Embodiment of the invention]

 The balancing device 10 provided by the present invention is particularly suitable for operation of a keyboard as a space key as shown in FIG. 1 because the space key is usually elongated. The structure can be applied to other keys. The balancing device 10 of the present invention includes balancing rods 2 and 2 '. The balancing rods 2 and 2' have a substantially C-shape in plan view, and have openings facing front and rear in the key top 1 of the space key. And these two balancing rods 2, 2 'are arranged to intersect in a side view. In this embodiment, the equilibrium rods 2 and 2 ′ have a first pivot rod 21, and both sides of the first pivot rod 21 are bent vertically to form a support rod 22. The other ends of the rods 22 are each further bent inward to form a second pivot rod 23 parallel to the first pivot rod 21. Before and after a position corresponding to the space key on the upper surface of the base 3 of the keyboard, a pivotal contact portion 31 is formed, and these pivotal contact portions 31 are formed as sliding grooves. In addition, pivoting portions 11 are respectively provided near the front and rear ends of the inner wall of the key top 1 of the space key, and these pivoting portions 11 are fixed grooves.

As shown in FIG. 2, at the time of assembly, the first pivoting rods 21 of the two balancing rods 2, 2 ′ are pivotally connected to the pivoting portion 31 of the base 3, respectively. The 2 'second pivot rods 23 are pivotally connected to the pivot portions 11 of the key top 1 respectively, and at the same time, the guide 4 on the keyboard is also pivoted to the key top 1, so that when the user presses the space key, When the pivot 41 of the guide 4 moves toward one side, the second pivot connecting rod 23 of the two balancing rods 2 and 2 'also moves toward one side, and the entire key top 1 of the space key is pressed downward. Then, the rubber cup 5 is pressed, so that the rubber cup 5 and the circuit on the substrate in the keyboard come into contact with each other to form a conductive state.

FIG. 3 shows another embodiment of the present invention, in which two left and right sides of two balancing rods 2 and 2 ′ are movably pivotally connected to each other and integrated. It is pivoted like scissors.

In the present invention, the balance rods 2 and 2 ′ are provided on both front and rear sides of the space key, so that the force is transmitted to the space key even when the space key is pressed at any angle. As a result, reliable pressing is achieved.

[0014]

[Effect of the invention]

 Taken together, the present invention is applied to a light and thin keyboard of a notebook computer in particular, and can prevent the situation of uncertainty of pressing, and has a certain practicality, novelty and industrial value. It can be said that there is.
