The push button is provided with a hingeably groove forming portion and a second slidingly retaining guideway that form a hinge axis across the longitudinal direction of the base plate. The hinge groove forming portion has front and rear bearing support members spaced apart from each other on the hinge shaft. This front and rear bearing support member has a front and rear outboard wall at the hinge shaft and forms a distance longer than the distance formed between the two hook ends of the pair of link arms of the pair of link arms. do. The front and rear outboard walls have front and rear recesses to cross the front and rear outboard walls and form a front and rear bearing surface that faces up from the bottom of the push button. When the front and rear hook ends fit inside the hinge groove formation, these hook ends are initially forced away from the hinge shaft, so that these hook ends slide forward over the front and rear outboard walls as described above. The pressure fits into the rear recess so that each of the front and rear hook ends is rotatably retained on the front and rear bearing surfaces.

Computer key

The present invention relates to a computer key, and more particularly, to each pair of hooking ends of two pairs of linking arms arranged pivotally between a base plate and a push button. and a push button including a retaining groove forming portion provided with a novel hinge-type connecting portion at a lower side in a novel structure.

1 and 2, a conventional computer key includes a base plate 40, a membrane circuit 60, a push button 11, an upright elastomeric biasing member 50, and first and second connections. It consists of a linking frame member 12 composed of a frame 121, 122.

As shown in FIG. 1, the base plate 40 comprises a first hinge retaining groove 401 forming a first hinge axis and the first hinge retaining groove 401 described above in the longitudinal direction of the base plate 40. And a first sliding retaining guideway 402 formed spaced apart from, forming an actuation area 403 therebetween. The first hinge axis is an axis transverse to the longitudinal direction of the base plate 40.

Membrane circuit 60 is arranged in operating region 403.

The bias member 50 is formed such that the upper depressing portion 501 and the upper pressing portion 501 are spaced apart from the operating region 403, so as to press the operating region 403 as well as the contact region of the membrane circuit 60 to the lower interval portion 502. Configured to generate an electrical signal.

The push button 11 is arranged to operate the pressing portion 501 of the bias member 50, and has a second hinge retaining groove 112 and a second sliding retaining guide 113 forming a second hinge axis on the lower side. The second hinge holding groove 112 and the second sliding holding guideway 113 are disposed at diagonal positions with respect to the first sliding holding guideway 402 and the first hinge holding groove 401 of the base plate 40, respectively.

The first connecting frame 121 comprises: a pair of first connecting arms 1211 each extending in a first transverse direction with respect to the first hinge axes; A first bracing member 1214 disposed in the direction of the first hinge axis therebetween such that the pair of first connecting arms 1211 are spaced apart from each other; First front and rear hook ends 1212 and 1213 extending respectively away from the pair of first connecting arms 1211 in the direction of the first hinge axis to be rotatably retained in the first hinge retaining groove 401; And a pair of first hooking fingers 1215 extending in parallel with one of the first front and rear hook ends 1212, 1213 from the pair of first connecting arms 1211, respectively. The first hook finger 1215 is fitted into the second sliding retaining guide 113 and is retained as if sliding.

The second connecting frame 122 comprises a pair of second connecting arms 1221 each extending in a second transverse direction with respect to the second hinge axes; A second bracing member 1224 disposed in the direction of the second hinge axis therebetween such that the pair of second connecting arms 1221 are formed at a distance from each other; A transverse shaft 1222 disposed between the pair of second connecting arms 1221 in the direction of the second hinge shaft and fitted into the second hinge holding groove 112 to be rotatably retained; And a pair of second hook fingers 1223 extending from the pair of second connecting arms 1221 in parallel to the transverse axis 1222, respectively.
