Title:
KEYBOARD TILT ADJUSTOR
Document Type and Number:
Japanese Patent JPS62190520
Kind Code:
A
Abstract:
The inclination adjusting arrangement (11) is applied to a keyboard having a base structure (13) in which a plurality of keys is mounted. The keybard is provided in its lower portion with fixed front support feet and rear support feet (18). The rear feet (18) can project by varying amounts from the bottom (16) of the base structure (13) in such a way that the angle of inclination of the plane of the keys is variable with respect to the desk top. For the purposes of adjusting the degree of projection, the rear feet (18) are pivoted and movable along their own axis by means of a slot (31) which co-operates with a fixed pivot pin (21) on the base structure (13). Each rear foot (18) comprises a positioning tooth (23) which is disposed opposite a support surface (22) and which is capable of selectively engaging with a seat of a series of seats (24, 26,27) of the base structure (13). Resilient means (28) which co-operate with the pin (21) hold the positioning tooth (23) engaged with one of the seats. The seats (24, 26 and 27) are disposed on a circular arc substantially coaxial with the fixed pin (21), in different angular positions for varying the distance of the support surfaces (22) from the plane of the keys. The resilient means comprises a resilient blade (28) which is bent and curved in such a way that its free end (33) engages the fixed pin (21).
