Abstract

The present invention relates to a keyboard, such as a computer keyboard, wherein at least one key is a self-locking key.

Description

Keyboard

Technical Field

The present invention relates to a keyboard, for example a computer keyboard.

Background

The conventional computer keyboard is a wired keyboard, connected to and powered by a computer through a wire, and generally has an indicator light to indicate whether the computer is in some state, such as capitalization locking, digital locking, rolling locking, etc., and a user can determine whether to press a corresponding locking key on the keyboard under the indication of the indicator light, such as capitalization locking (generally abbreviated as Caps Lock), digital locking (generally abbreviated as Num Lock), and rolling locking (generally abbreviated as Scoll Lock). Because the power supply of the wired keyboard is sufficient, the problem of excessive power consumption caused by the indicator lamp is not worried about.

With the development of wireless technology in recent years, more portable wireless keyboards have become more and more widely used. The wireless keyboard is generally powered by a battery, but if the locking state is indicated by a traditional indicator light, the power consumption is undoubtedly greatly increased, so that the power of the battery is quickly exhausted, and the battery needs to be replaced frequently. In particular, many users prefer to use the keypad area for numeric input so that the number lock indicator lamp is always in an illuminated state; there are also some users' personal habits or work requirements that cause the capitalization lock or scroll lock indicator lights to be constantly on. In such a case, the consumption of the battery is further accelerated.

In order to avoid this problem, many manufacturers have designed keyboards without indicator lights, but in this way, users cannot grasp the locking conditions, such as capitalization locking and digital locking, when using the keyboard, which causes great inconvenience to the users, especially when the input contents cannot be seen from the screen, such as inputting passwords.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to have the button design of locking function to become the auto-lock type button, instruct the locking state through the position of auto-lock type button, do not need the pilot lamp, solved power consumptive problem for wireless keyboard's user need not change the battery frequently. The capitalization locking key can be easily operated by the little finger of the left hand, and the capitalization locking state can be sensed by vision or the touch of the little finger, so that the device is very convenient; the number lock key and the scroll lock key do not need to be frequently used for most users, and thus it does not cause any inconvenience in use even if they are configured as a self-lock type key.

Specifically, the present invention relates to a keyboard wherein at least one key is a self-locking key. In a preferred embodiment, one or more of the capitalization locking key, the number locking key, and the scroll locking key on the keyboard are self-locking type keys. In a preferred embodiment, the capital-lock key on the keyboard is a self-locking type key. In a preferred embodiment, the number locking key on the keyboard is a self-locking type key. In a preferred embodiment, the scroll lock key on the keyboard is a self-locking type key. In a preferred embodiment, the keyboard is a wireless keyboard. In a preferred embodiment, the keyboard does not have a lock indicator light. In a preferred embodiment, the self-locking key has a mark thereon for guiding a user.

Drawings

FIG. 1: taking the capitalization lock key as an example, a schematic diagram showing the self-locking key in the ON state is shown.

FIG. 2: taking the capitalization lock key as an example, a schematic diagram showing the self-locking key in the OFF state is shown.

FIG. 3: taking the case of a capital lock key, one example of a mark for guiding the user is displayed.

Detailed Description

The self-locking key in the specification refers to a key which is locked at a low position when pressed for the first time and rebounds to an initial position when pressed for the second time, and the key is repeatedly pressed in such a way. The self-locking key is a key that is commonly used in the prior art, and all known keys that can switch positions by pressing or keys that are improved along with the development of technology in the future but still maintain the position switching function belong to the "self-locking keys" described in this specification.

In this document, a state in which the lock key is pressed is referred to as an "ON state", and a state in which the lock key is reset is referred to as an "OFF state". According to general user habits, the ON state corresponds to a case where a conventional keyboard indicator is ON (e.g., an uppercase state or a state where a keypad area inputs a number), and the OFF state corresponds to a case where a conventional keyboard indicator is OFF (e.g., a lowercase state or a state where a keypad area inputs a cursor); but may be set in the opposite case. The ON state and the OFF state are respectively connected to the computer through different circuits, so that the computer is switched to the corresponding working state, and the method can also be realized by adopting the technical means commonly used in the field of computers.

The technical solution of the present invention will be further explained below with reference to the specific embodiments and the accompanying drawings. It should be understood that these specific embodiments are for illustration only and are not intended to limit the scope of the invention. Although the following specific examples are given using Caps Lock (Caps Lock), it should be understood that the same design and processing can be applied to a number Lock (Num Lock), a scroll Lock (Scoll Lock), and other keys (for example, Fn key, etc.) having a Lock switching function as required.

As shown in fig. 1, the caps lock key is switched to an ON state when it is pressed, and is locked in a low position. Whether the user looks at the keyboard or touches the keyboard with a finger, the user can quickly know that the keyboard is in an ON state, namely the state of outputting capital letters. As shown in fig. 2, the capitalization lock key is switched to the OFF state when it is pressed again, and the key returns to its original position. Whether by eye or finger touch, the user can quickly know that it is in the OFF state, i.e., the state of outputting lower case letters.

The keyboard of the present invention may also have indicia for guiding the user, and fig. 3 is an example given by way of capitalization locking keys. The indicia may be either drawn on the keys as in fig. 3 or written on the product packaging or instructions to enable the user to easily grasp the use of such keys.

Modifications to the present application based on the prior art may occur to those skilled in the art upon reading the present specification, and such modifications or equivalents also fall within the scope of the appended claims of the present application.
