Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a computer keyboard.

[0002]

[Prior art]

 For conventional computer keyboard keys, necessary modifications were made to the key-to-bottom structure to meet the needs of the industry in order to maintain the height between the keys and the bottom and to ensure that the operation was successful. ing.

[0003]

[Problems to be solved by the invention]

 However, the general contractor applies the crossed rod system to achieve the function, but most of these crossed rods are on one side, the lower end is the pivotal fixed position point, and the other side is on the other side. The lower end should slide horizontally, and when the key is pressed, one side that slides horizontally will sink quickly and tilt easily, and the center pivot point will also often move, causing a shift or tilt. A stable situation arises, causing inconvenience to the user.

[0004] An object of the present invention is to provide a computer keyboard that can prevent tilting and shifting. Another object of the present invention is to provide a computer keyboard capable of reducing a distance between a key and a pedestal.

[0005]

[Means for Solving the Problems]

 According to the computer keyboard of the first aspect of the present invention, the cross support slide pivotally connects the left and right support slides to each other. The center limit rods protrude outside the pivot point, and the left and right slide rods protrude outward on both sides of the horizontal rods provided at the bottom ends of the two left and right cross-support slides, respectively. Each has a U-shaped groove, and an upper end is provided with an inward sliding bar. The key is provided with two sets of sliding holes arranged in parallel on both sides of the bottom surface. On the left side and the right side of the keyboard seat, the restriction pieces extending inward are respectively extended. The front side and the rear side of the keyboard seat are provided with inverted L-shaped sliding grooves at both ends, and a slide rail composed of two vertical rods is formed at the center. The slide bars of the left and right cross-support slides are respectively movably fitted into the slide holes of the keys, and the slide bars are respectively movably engaged in the inverted L-shaped slide grooves of the keyboard seat, and at the same time, the U-shaped grooves are provided. Are also engaged across the left and right restriction pieces, and the center restriction rod is movably supported by the slide rail.

[0006] Therefore, when the elastic silicone rubber is compressed by the key, the left and right cross-supporting slides descend at the same time in the vertical slide rail around the center limit rod, and the slide and the slide are connected to the key hole and the keyboard. The keys are pushed without shifting or tilting by moving in the inverted L-shaped groove of the seat, and the left and right cross-supporting slides are compressed and laid flat in the keyboard seat. The height of the keyboard room can be reduced.

Slide bars 1212 and 1222 are provided. The key 2 has two sets of left and right sliding holes 21 (21 ') and 22 (22') arranged in parallel at appropriate positions on both sides of the bottom of the key.

The keyboard seat 3 is provided with left and right openings 31 and 32 having appropriate widths on the left and right sides thereof, respectively. The left and right openings 31 and 32 have left and right restriction pieces 311 and 321 respectively. Are extended inward, and opposite L-shaped sliding grooves 331 and 332 are provided at both ends of the front side 33 of the front and rear sides 33 and 34 so that the openings are directed in the opposite directions upward. There are provided inverted L-shaped sliding grooves 341 and 342 whose openings are directed in opposite directions, respectively, and between two sets of inverted L-shaped sliding grooves 331 and 332 of front and rear sides 33 and 34, respectively. At the middle part between 341 and 342, the front left and right vertical rods 333 and 333 'and the rear left and right vertical rods 343 and 343' are provided in parallel, respectively, which are the front vertical slide rail 334 and the rear vertical rod. A slide rail 344 is formed.

As shown in FIGS. 1 to 3, two pivot shafts 1121 and 1111 provided on a left support frame 11 of the cross support slide 1 are respectively connected to two pivot contact holes 1211 and 111 of a right support frame 12. 221 and is fixed in position, and the left and right slide bars 1113, 1123 of the left support frame 11 are placed in the two parallel right slide holes 22, 22 'of the key 2, and the left of the right support frame 12 is fixed. , Right slide bars 1212, 1222 also rest in the two parallel left slide holes 21, 21 'of key 2, whereby the cross-support slide 1 and key 2 are connected, and four sets of slide bars 1113, 1123 are provided. , 1212, 1222 can move horizontally within the four sets of slideways 22, 22 ', 21, 21'.

Further, the left and right sliding rods 1131 and 1132 of the left support frame 11 are respectively set in the inverted L-shaped sliding grooves 331 and 341 on the front side 33 and the rear side 34 of the keyboard seat 3, and the right support frame 12 and The left and right slide rods 1231 and 1232 of the keyboard seat 3 are also set in separate inverted L-shaped slide grooves 332 and 342 on the front side 33 and the rear side 34 of the keyboard seat 3, respectively. 1232 is capable of horizontally moving outward in four sets of inverted L-shaped sliding grooves 331, 341 332, and 342, and at the same time, the two center limiting rods 1112 and 1122 of the cross support slide 1 are Just in front of the keyboard seat 3 and in the position of the rear vertical slide rails 333, 333 ', the key 2, the cross support slide 1, the keyboard seat 3 are connected, and the elastic silicone rubber is used. 4, the key 2 is pushed up, and when the key 2 is not pressed, the four pairs of the sliding rods 1131, 1132, 1231, and 1232 are not separated by the four sets of inverted L-shaped sliding grooves 331, 341, 332, and 342. Is restricted to

As shown in FIGS. 4 and 5, when the key 2 is pressed, the elastic silicon rubber 4 is pressed, and at the same time, the cross-support slide 1 is compressed. The two vertical slide rails 333, 333 ′ of the keyboard seat 3 are vertically lowered, the movement of the center point of the key 2 is avoided, and the compression of the elastic silicone rubber 4 is maintained vertically. The rods 1131, 1132, 231, and 1232 are in four sets of inverted L-shaped slide grooves 331, 341, 332, and 342, and the four sets of slide bars 1113, 1123, 1212, and 1222 are four sets of slide holes 22 and 22 ′. , 21, 21 ′ horizontally outward, and at the same time, as shown in FIG. 5, with two U-shaped grooves 1133, 1233 of the cross support slide 1, the left side of the keyboard seat 3, It is placed on the right side restriction pieces 311 and 321. In this way, the cross-support slide 1 can be operated stably and reliably without shifting or tilting.

Further, since the four sets of slide rods 1131, 1132, 1231, and 1232 are all within the thickness range of the base A, the height between the key 2 and the base A is reduced, and the entire keyboard is further thinned. .
