Abstract
The utility model relates to a fatigue-preventing cushion, comprising electric source (1), an electric apparatus controller (2), and two groups of transmission mechanisms. Each group of the transmission mechanism is operated individually and is operated in turn. Strip movable plates (12) are arranged on the eccentric wheel group (11) of the transmission mechanisms. Decorating protection material (13) is laid on the surface composed of strip movable plates. The transmission mechanisms are driven by a direct current motor (3), A gap bridge speed reduction chain wheel (7) and a gap bridge speed reduction chain wheel (8) are driven by a main drive chain wheel (5) which is driven by a main drive shaft (4), the main drive shaft (4) is connected with the direct current motor (3), the eccentric wheel group (11) is driven to rotate by a synchronous drive chain (9), and the strip movable plates (12) arranged on the eccentric wheel group (11) are shifted up and down. The utility model has the advantages of achieving the purpose of often changing the pressed parts of buttocks, improving the blood circulation of buttocks, lightening the fatigue of prolonged sitting, and preventing patients from producing bedsore easily.
Description
The utility model relates to a kind of life, work seat cushion.
There is a big chunk time to be seated in the daily life, for the normal person, under the particular job condition, keep a kind of sitting posture not change for a long time, or old person conversion sitting posture arbitrarily due to illness, the capital causes poor blood circulation owing to the pressurized position of buttocks remains unchanged for a long time, make people's fatigue easily, patient Yi Sheng bedsore.
The purpose of this utility model is to provide a kind of dependence machine driving, under the situation of the notice of not disperseing the people (human body does not have the sense of rising and falling), constantly changes the Fatigue-preventing cushion at buttocks pressurized position.
Fatigue-preventing cushion of the present utility model comprises power supply, appliance controller and two groups individual operation, the transmission mechanism that takes turns to operate separately, on the eccentric group of transmission mechanism, lay the bar shaped portable plate, lay the decoration protective materials on the surface that constitutes by portable plate, described transmission mechanism is driven by direct current generator, making the final drive shaft that is attached thereto drive sprocket for main drive rotates, thereby drive the eccentric group running, make the bar shaped portable plate that is placed on the eccentric wheel produce upper and lower displacement.
Fatigue-preventing cushion of the present utility model takes turns to operate by two sets of transmission mechanism, make the bar shaped portable plate that is subjected to buttocks pressure do the upper and lower displacement of intermittent time respectively, reach the purpose of frequent change buttocks depressed position, the buttocks blood circulation is improved, alleviate the fatigue of sitting, operating efficiency is improved, and can make patient be difficult for giving birth to bedsore, alleviates the misery that long-term seat crouches.
Below by embodiment the utility model is elaborated.
Figure 1 shows that according to the Fatigue-preventing cushion structural representation that the utility model proposes.
Fig. 2 is transmission mechanism schematic diagram (front view).
Fig. 3 is transmission mechanism schematic diagram (vertical view).
As shown in the figure, this Fatigue-preventing cushion comprises D.C. regulated power supply 1, and two transmission mechanisms that overlap independent operating separately, take turns to operate controlled of the appliance controller 2 that mainly is made of relay.Described transmission mechanism comprises direct current generator 3, the final drive shaft 4 that is connected with motor 3, the gap bridge ratio wheel 7 and 8 that is installed in the sprocket for main drive 5 on the axle 4 and turns round by driving chain 6.The driving chain 9 that connects ratio wheel 8 and eccentric wheel sprocket wheel 10 drives the eccentric group 11 that is installed on the camshaft and rotates.Lay bar shaped portable plate 12 on the eccentric group, the moving plate of this bar shaped activity can the displacement with the upper and lower displacement of eccentric group.Lay on the surface that is constituted by the bar shaped portable plate and decorate protective materials 13.In all member is all packed a framework 14 into, form the complete seat cushion that can move.
Seat cushion of the present utility model adopts and exchanges 220v (direct current 12v) power supply, available relay give motor is set earlier working time to regulate the upper-lower position time interval of eccentric group.When direct current generator by worm gear reducer when final drive shaft 4 and sprocket wheel 5 drives gap bridge deceleration sprocket wheels 7 and 8 runnings, driving chain 9 will drive eccentric group 11 and rotate 12 picking-ups of bar shaped portable plate, behind extreme higher position (stressed), another group is done 90-120 ° of rotation by the eccentric group of another one motor transmission mechanism control, the bar shaped portable plate of laying on it is done to bottom offset, enter and free stress, so continuous periodic duty, the supporting surface of portable plate is constantly changed, change buttocks pressurized position purpose thereby reach.Described eccentric wheel can be replaced by cam, is arranged in parallel two groups on the plane of seat cushion, and portable plate is installed on eccentric wheel or the cam, stipulates the scope that it is up and down by framework, and upper and lower displacement is no more than 3cm.This displacement is to carry out under the condition of the notice of not disperseing the people (human body does not have the sense of rising and falling).Laying the protected decoration material on the plane of being made up of bar shaped portable plate 12, can be textile or other thin material.
Also can be made into each furniture such as chair, mattress according to structure of the present utility model with form.The power control part branch of this pad is very simple motor on-off circuit, can select for use a relay to realize.
Claims (3)
1. Fatigue-preventing cushion, comprise power supply (1), appliance controller (2), it is characterized in that also comprising two groups of transmission mechanisms of taking turns to operate of individual operation separately, on the eccentric group (11) of transmission mechanism, bar shaped portable plate (12) is installed, lay on the surface that constitutes by the bar shaped portable plate and decorate protective materials (13), described transmission mechanism is driven by direct current generator (3), make the final drive shaft (4) that is attached thereto drive sprocket for main drive (5) and drive gap bridge deceleration sprocket wheel (7) and (8) and Synchronous Transmission chain (9) drive eccentric group (11) rotation, make bar shaped portable plate (12) upper and lower displacement of laying on it.
2. seat cushion as claimed in claim 1 is characterized in that described eccentric group in seat cushion plane parallel layout, is spaced, symmetrical two groups, respectively by independently motor transmission mechanism driving separately.
3. as claim 1 and 2 described seat cushions, it is characterized in that described eccentric wheel can replace with cam.
