Description
The utility model relates to a kind of piano stool, relates in particular to a kind of lifting piano stool.
At present, piano stool is divided into liftable and two kinds of liftables not on the market, and liftable piano stool can be divided into following two kinds again because of its lifting principle difference, and a kind of is the spring lifting, utilizes the frictional force of steel pipe inside and outside wall and the locking intercolumniation height that is locked.Use a period of time, lifting repeatedly, has ground on locking post surface, and frictional force reduces, and during use, just the phenomenon that glides can occur.Another kind utilizes leading screw to advance and makes the lifting of stool face.In the use, when the excitement of player's mood, when firmly playing piano, the downward active force of arm increases suddenly, and leading screw can gently move down, and service time one is long, and after the leading screw wearing and tearing, the speed that moves down can be accelerated.All there is the not high problem of degree of stability in these two kinds of lifting piano stools in a word.
The purpose of this utility model provides a kind of degree of stability height, and easy to operate, rising or falling speed is fast, durable stepping formula lifting piano stool.
The purpose of this utility model is by providing the piano stool with following structure to realize.This piano stool comprises the stool face, stool leg, frame, lowering or hoisting gear; Described lowering or hoisting gear is arranged between stool face and the frame, and it comprises: entablature, sill, brandreth, stepping locking plate, spring, handle, connecting axle, locking plate connecting axle; Described stepping locking plate is provided with some open slots, and is fixed on the connecting axle with handle; Described spring one end is fixed on the stepping locking plate, and the other end is fixed on the entablature; Described entablature, sill are offered slideway respectively in the same side, entablature is fixed on the bottom surface of described stool face, and described sill is fixed on the described frame; Described brandreth is by two cross-articulation of symmetric arrangement riser at axis, uses axle, lower shaft, last movable axis, and following movable axis is formed by connecting, and riser one end is affixed with last axle, lower shaft respectively, and the other end is affixed with last movable axis, time movable axis respectively; In the described brandreth to go up axle, lower shaft hinged with described entablature, sill respectively, last movable axis, drawing together moving axis down can be respectively along described slideway slip.
For fast lifting, a tension spring is set on the brandreth axis, both ends of the spring is stuck on movable axis, the following movable axis.
The stepping locking plate can be offered a plurality of open slots, and in the practice, the difference of height during according to people's standing and sitting gesture has been offered four open slots, to adapt to different users's needs on the described stepping locking plate.
The stool leg can be that various materials are made, and the steel plate making is firmer, bearing capacity is bigger and adopt, and can be welded with bolt, can the frame connecting plate is fixing with it by bolt.
The top layer of described stool face can be artificial leather or surface, and the centre is provided with high recovery sponge, and the bottom surface is a medium-density plate, and is both comfortable and be beneficial to cleaning.
Described frame can be with multi-plywood making, four jiaos of rectangular shaped rim that are formed by connecting with iron connecting plate.
During use, about 1/3 circle of rotary handle is opened the stepping locking plate, and the stool face raises under the effect of tension spring, and when arriving proper height, the reverse rotation handle makes stepping locking plate open slot snap in axis, and stool face height is just determined.When reducing stool face height, rotary handle is opened the stepping locking plate, with hand to pressing down the stool face, when arriving institute and wanting highly, the reverse rotation handle, the stepping locking plate is locked and is got final product.
Piano stool provided by the utility model is compared with aforesaid piano stool and is had the following advantages: degree of stability height, no downslide phenomenon; Easy to operate, rising or falling speed is fast, and the user only need rotate about 1/3 circle of the handle that is arranged on stool right side of face or left side, just can adjust stool face height, goes back to handle again, locks promptly to finish once to rise or fall; Durable.
Below in conjunction with accompanying drawing, describe a preferred embodiment of the present utility model in detail.
Fig. 1 is the side view cutaway drawing of stepping formula lifting piano stool;
Fig. 2 is the schematic perspective view of lowering or hoisting gear in the stepping formula lifting piano stool.
See figures.1.and.2, piano stool of the present utility model comprises the stool face, stool leg, frame and lowering or hoisting gear.Wherein, the stool face is the seat surface 14 that artificial leather or corium are made from top to bottom, high recovery sponge 15, and seat board 17, seat board frame 18, seat board 17 adopts medium-density plate.Stool leg 21 usefulness steel plates are made through punching press, and firm, bearing capacity is big; Be welded with bolt on stool 21 legs, by bolt the stool leg be fixed on the frame connecting plate 2, such piano stool overcomes the easily loosening shortcoming of bolt on the general piano stool timber toe; Footmuff 20 is housed below, makes of anti-slip material.Frame is to be that 1, two the minor face frame 3 of two long margin frames and the connecting plate made of iron 2 of multi-plywood is formed by connecting with material.Lowering or hoisting gear is arranged between stool face and the frame, and it comprises brandreth, stepping locking plate 12, extension spring 13, entablature 22, sill 23, tension spring 5, handle 6, connecting axle 24; Riser 10, riser 11 cross-articulation on axis 7, its right-hand member respectively with last axle 8, lower shaft 9 is affixed, its left end respectively with last movable axis 16, following movable axis 4 is affixed, constitutes brandreth with this; Two entablatures 22 separate certain distance and are contained in abreast on the seat board 17 of stool face, two sills 23 are contained on the frame equally abreast, upper and lower crossbeam is provided with slideway 25,26 at left end, above-mentioned brandreth is by last axle 8, lower shaft 9 is fixed in entablature 22 respectively, on the right-hand member of sill 23, and last movable axis 16, under draw together moving axis 4 and can establish slideway 25,26 and slide.When sliding to the right, axis 7 raises.When sliding left, axis 7 reduces, and the stool face raises with axis 7 or reduces; Stepping locking plate 12 is provided with four open slots, makes the stool face can change four gears, adapts to different users's needs.Stepping locking plate 12, handle 6 is affixed with connecting axle 24, and in order to lock, the stool face is stable can be provided with two stepping locking plates, and connecting axle 19 can make two stepping locking plates synchronous.During rotary handle 6, stepping locking plate 12 is rotated counterclockwise around connecting axle 24, and locking plate is opened, the stool face is transferred to correct position after, during reverse rotation handle 6, the open card on the locking plate makes the fixed-site of axis 7 on axis 7; Extension spring 13 1 ends are fixed on the stepping locking plate 12, and an end is fixed on the entablature 22, and the effect of extension spring 13 is that locking plate 12 is resetted, and make locking plate locking, are difficult for deviating from.Accelerate in order to make rising or falling speed, one tension spring 5 is set on axis 7, two ends are stuck in movable axis 16, on the following movable axis 4, when opening stepping locking plate 12, under the effect of tension spring 5, the stool face raises fast, when being raised to correct position, and rotary handle 6, stepping locking plate 12 blocks axis, and stool face height is fixed.
