Abstract

Keys that are easily fitted on a computer keyborder mainly consist of a key member having at least one guide bar coupled to the hook and the holding member and a balance bar positioned between the hook and the holding member. Such keys with balancing bars and fastening elements arranged directly inside the keys are best suited to forming keys that are twice, three or four times larger in size than ordinary keys. When such double, triple or quad size keys need to change their position on the keyboard, in the face of special needs in operation, simply insert the keys into any desired key hole formed on the keyboard. Put it in. No other balance bar or fasteners need to be provided on the keyboard and no other tools are needed to insert the keys into the keyboard.

The present invention relates to a key inserted into a computer keyboard, and more particularly to a key structure consisting of a fixing member, a balancing device and a key member. The key structure according to the present invention can be applied to any computer keyboarder for commercial and industrial purposes.

Conventional computer keyboards usually consist of keys of regular size and keys of twice, three and four times the size. The double, triple and quadruple keys all contain a balancing device to facilitate smooth operation of the keys. As shown in FIG. 1, a conventional double size key 10 has a balance bar 20. As shown in FIG. The balance bar 20 is inserted into two fixing means 30 formed on the keyboard seat 40 and fixed. At this time, the balance bar 20 is connected to the key 10 by a special tool. In a conventional keyboard, the arrangement of the keys present on the keyboard is predetermined. That is, the fixing means 30 is pre-installed at the position where the keys of the double, triple and quadruple sizes are arranged, which is inserted into the fixing means 30 in which the balance bar 20 is pre-installed in the assembly plant. In order to do so, the key 10 must be connected to the balance bar 20 with a special tool.

There is no problem in the manufacturing plant producing a conventional key board by the above method. However, for keyboards that can be adopted and programmed into a sales system or industrial system, double, triple, and quadrature keys can be freely changed and placed by the user according to various needs, such as business, contract, accounting system or special application. have. Therefore, it would be better to provide the locking means 30 in the position of all the keys. However, in order to install so many fastening means 30, the space available on the keyboard is too limited. In addition, since a special tool is needed to connect the balance bar 20 to the key 10, it is difficult for the user to completely connect the balance bar 20 to the key 10 by force alone.

The primary objective of the present invention is to develop a double, triple or quad sized key structure that allows an inexperienced user to easily fit in the desired position on the keyboardboard, without using any special tool to connect the balance bar to the key. will be.

The key structure according to the present invention is mainly composed of a key member having at least one guide bar coupled to the hook and the fixing member, and a balance bar positioned between the hook and the fixing member. Such keys with balancing bars and fastening elements arranged directly inside the keys are best suited to forming keys that are twice, three or four times larger in size than ordinary keys. When such double, triple or quadruple sizes of keys need to change their position on the keyboard, in the face of special needs in operation, simply insert the keys into any desired key hole formed on the keyboard. Put it in. No other balance bar or fasteners need to be provided on the keyboard and no other tools are needed to insert the keys into the keyboard.

See FIGS. 2 through 6. The present invention relates to a key that can be easily fitted to a computer keyboard. Keys that can be easily fitted include a balancer which further comprises a key member 1, a holding member 2 and a balance bar 3 and a cross balancer 4.

The key member 1 is composed of upper and four sidewalls, and a space is defined between the sidewalls. On the inner surface of the key member 1, two hooks 11, at least one guide bar 12 and a fixing bar 13 are formed.

The fixing member 3 is formed at a position where the position protrusion 21 and at least one guide hole 22 are defined at both sides.

The balance bar 3 is approximately It has a shape of, and comprises a ridged area 31 on the opposite side of the balance bar 3 open and two end areas 32 on both sides open.

When the key structure according to the present invention is in the assembled state, the guide bar 12 is inserted into the guide hole 22 of the fixing member 2, and the ridged area 31 of the balance bar 3 is fixed. It is firmly attached to the fixing member 2 by the position protrusions 21 located on both sides of the member 2, and the two end regions 32 of the balance bar 3 are two hooks 11 on the key member 1. Maintained appropriately). This basic key structure is not only a double size key 1A shown in FIGS. 2 and 3, but also a triple size key 1B shown in FIG. 4 and a quad size key shown in FIGs. 5 and 6. Also applicable to (1C).

In the case of triple or quadruple keys 1B and 1C, a cross balancer 4 may be further included to form the keys relatively. In order to install the cross balancer 4, a first slide space 14 and a first positioning means 15 are formed on the inner surfaces of the key members 1B and 1C, and on the fixing member 2, the first slide space 14 is formed. The second slide space 23 and the second positioning means 24 are formed at positions relatively facing the slide space 14 and the first positioning means 15. The cross balancer (4) works with the balance bar (3) to ensure that the three and four size keys, which are much larger than the normal and double size keys, are balanced in both directions. The cross balancer 4 allows the operation of the larger keys above to be pressed in a softer way. In addition, the key member 1 further has a first protrusion 16 formed on the inner surface thereof, and a second protrusion 25 formed on the fixing member 2 opposite to the key member 1. The spring 5 is provided between the first and second protrusions 16 and 25 in order to be able to return to the original position after the key member 1 is pressed.

When each individual key made up of the balance bar 3, the fixing member 2, and the key members 1A, 1B, and 1C described above is installed in the keyboard, the keyboard is the balance bar ( There is no need for any fastening means to hold 3) in place. The easily insertable key according to the present invention can be freely inserted into any desired key hole 50 on the key boarder by simply pressing the fixing bar 13 on the key member 1 by hand. Also, no other tools are needed. In this way, the user can easily and freely change the position of the double, triple and quad size keys on the keyboard, when he or she wishes to change the position of the key to perform special tasks in the operation of the computer.

Characteristically, hooking means 131 are formed at the ends of two adjacent surfaces of the fixing bar 13 provided on the key member 1, respectively. The easy-to-fit key made of the respective elements can be positioned horizontally or vertically on the keyboard by one of the two hooking means 131 being fitted in the keyhole 50.

By the arrangement described above, double, triple and quad size keys are easily operated and can be easily repositioned on the keyboard as needed. In addition, no fastening means are needed on the keyboard to secure the balance bar in the proper position, and no special tools are needed to key the keyboard.
