Description

A kind of multifunctional table desktop piano

Technical field

The present invention relates to Multifunctional piano, and in particular to a kind of multifunctional table desktop piano.

Background technology

The height of Horizontal piano, because hammered string instrument must be always one as the key lever of keyboard play in the lower section of string The straight batten of root.What is write inside 2002 national standards is that mid-game is not less than 57 centimetres apart from ground, and white key is not low apart from ground In 64 centimetres, why to ensure mid-game ground clearance, be that, because keyboard is placed in mid-game, must assure that keyboard Highly in the height for being adapted to play.

With the development and progress of social economy, piano is gradually evolved into one by a kind of high-grade proprietary musical instrument to today The amateurish musical instrument that kind of most people can use, the combination of it and other functional furnitures makes the function of piano by opening step by step Hair.

The content of the invention

The technical problems to be solved by the invention are to overcome existing technological deficiency that there is provided a kind of multifunctional table desktop steel Qin, solves traditional Horizontal piano because hammered string instrument must be always one as the key lever of keyboard play in the lower section of string The straight batten of root, can not ensure mid-game height and keyboard highly asking in the position for being adapted to play if reduction piano height Topic.The multifunctional table desktop piano by S types key lever extend changeover mechanism by the key lever bar of Horizontal piano be divided into above and below two keys Bar, is connected by rotating, and is realized piano height overall reduction while keep keyboard height, is adapted to have dinner, is moved to provide With the suitable height of other functional furnitures such as writing, the S type key lever changeover mechanisms develop the furniture table function of piano, save Space is used, the value of piano is improved and extend.

The technical problems to be solved by the invention are realized using following technical scheme：

Pedal is reinforced in a kind of multifunctional table desktop piano, including table, piano, S types key lever extension changeover mechanism and folding, and it is special Levy and be：

The piano is arranged on the side of table, and the S types key lever extension changeover mechanism is arranged on inside piano, and described fold adds Gu pedal is arranged on the lower section of piano.By the combination of piano and table, the value of piano is improved and extended, passes through S Piano key lever is extended and transferred by type key lever extension changeover mechanism, the scientific and reasonable mid-game for reducing piano height, is kept Original keyboard height, enables table piano to provide the suitable height for other functional furnitures such as being adapted to have dinner, move and write, So as to realize the value for improving piano dining table.

The table can be four square tables, polygonal table, conventional tables and desk, ping-pong table, billiard table, book with rotating disk Draw any one in table；

In actual use, table can be changed into dining table, desk, table tennis table, pool table etc. arbitrary shape according to actual needs The practicality platform of shape and area, and 4 or 6,8 table legs, the S types of its internal piano and piano are disposed as needed Key lever extends changeover mechanism and folding reinforcing pedal is constant.The top table top of piano is realized according to actual needs, while having just Other furniture or the sports facility functions such as meal, writing, motion, extend the use function and value of piano, reduce purchase The living space for put the spending of the articles for use such as other furniture, vacateing or save 5 to 20 square metres, helps to allow piano to come into common family Front yard, lifts the material life and cultural life quality of the common people.

The S types key lever extension changeover mechanism also includes upper key lever, upper extension key lever, key lever adapting rod, lower extension key lever With lower key lever, rotate and connect between the upper extension key lever and upper key lever, turn between upper the extension key lever and key lever adapting rod Dynamic connection, rotates between lower the extension key lever and key lever adapting rod and connects, rotated between the lower extension key lever and lower key lever Connection.

Pillow makees fulcrum during the key lever adapting rod stage casing is set, and is supportted by middle occipital branches and ensures key lever adapting rod left and right ends It is up and down.

Described fold reinforces pedal also including pedal, pedal support, pedal post, drive link, folding hinge and pedal reinforcing Device, the pedal is arranged on inside pedal support, the connection of the lower end of pedal posterior segment and drive link, at the top of the drive link with Pedal linkage mechanism, which is folded, in piano sets pedal post between switching, two adjacent drive links；The pedal column bottom is with stepping on Board mount is fixed, and top is connected by folding hinge and table bottom plate；The regulation that pedal carries out piano volume is reinforced by folding, When needing to use piano playing, it can will fold and reinforce pedal releasing, and when piano playing need not be used, reinforcing will be folded and stepped on Plate is folded and packed up, and any redundant space is not accounted for, convenient and practical.

The pedal bracing means also includes reinforcing pedal spanner, reinforces pedal shaft and tensioning plate, and the reinforcing pedal is pulled Hand is arranged on reinforcing pedal shaft top, and bottom is connected with reinforcing one end of pedal shaft, and the tensioning plate is arranged on reinforcing pedal shaft Bottom, also set up multiple cams on the reinforcing pedal shaft.When actual use, pedal spanner is reinforced by pulling, drives and adds Gu the cam on pedal shaft, axle is rotated down, jack-up tensioning plate, the frictional force on increase tensioning plate and ground, pedal support is improved Stability.

Multifunctional table desktop piano, whole height is 65-85 centimetres, suitable dining table height.

Beneficial effects of the present invention are：The extension changeover mechanism and folding of a kind of S type key levers of Multi-functional table piano are provided The solid device with pedal of superposition, on the premise of keeping keyboard terrain clearance to meet national standard, is scientifically and rationally reduced in piano Disk height, folds and reinforces pedal in good time, solves existing piano design, manufacturing philosophy and its manufacturing technology to multifunctional platform man Have the limitation of development, the traditional concept that horizontal grand piano is aristocratic professional musical instruments is changed, the playing function of piano The writing of utility function, desk with dining table draw a picture function, motor function of table tennis table billiards etc. organically combine at one piece, The practicality of piano is added, the house for purchasing the spending such as other furniture, vacateing or saving 5 to 20 square metres is virtually reduced Area, professional playing piano comes into ordinary people man and is expected to become a reality.
