The ultimate principle implied for the lifting device illustrated according to the present invention, with reference to Fig. 8 and 9.Fig. 8 and 9 is shown respectively
According to above-mentioned first embodiment (Fig. 1 to 3b) and corresponding embodiment, (wherein, brake unit 22 is by Fig. 4 to being formed
Brake unit 122 substitute, i.e. the second embodiment of lifting device) the different spring assemblies of a part of lifting device 10
Compare, in traditional spring assembly, the curve chart of the relation between expression power and the distance (path) of traveling.In the phase of measurement
Between, only main spring 19 is i.e., be not secondary spring 20 be movable.
In being expressed as I and the Conventional springs device curve chart that shows that in figs. 8 and 9, power is basic with the distance of traveling
Upper proportional, and do not have hysteresis effect to occur or the hysteresis effect of minimum only occurs.That is, to spring assembly prestrain or make
Spring assembly bias needed for compression stress correspond essentially to because of load alleviate or relaxing of spring and produce tensile force (point
Do not represent with A and B).
The first embodiment as described above modification i.e., there is (amendment) braking of adjustment power
The effect occurred in the lifting device 10 of device 22 represents in fig. 8 in the curve be expressed as II and III.With often
Rule spring assembly is the same, in the prestrain of load with to alleviate the power of period proportional to the distance of main spring 19 traveling respectively.So
And, alleviating period in load, i.e. in the period of opening of window the most as shown in Figure 1, power is followed and is started and at a B ' at an A ' place
Place terminate curve (reference A ', A ", B ', B " relate to both curve II and III).During the bias of spring assembly, i.e.
In the down periods of window, the power of generation is depicted from a B " extend to an A " curve.Therefore, the curve of generation depicts spring
Device releases different paths when pine and bias, causes delayed.Its reason is, brake unit 22 is the spring that main spring 19 applies
Power provides Braking.Delayed having the effect that when being placed in open position, window frame 1 is more stable.
Power or the moment that must be overcome on window frame 1 by operator to open or close window include: from slip
Frictional force part between seat 16 and guide portion 18, the gravity part acted on window frame 1 and the portion from spring assembly
Point.As described in initially, it is desirable to providing braking effect in the whole path of window, this braking effect be enough to make window open any
Under angle the most stable.
Gravity (or moment) depends on the open angle of window.The power (or moment) applied by spring assembly is in contrary direction
Upper effect is with balancing gravity part.As previously mentioned, the frictional force between sliding seat 16 and guide portion 18 open along with window and
Increase, it means that braking effect is minimum when window is close to closedown.This means to realize the purpose mentioned, at window
The braking effect that nearly closed position expectation is more, and less braking effect is expected in the position of bigger open angle.Note
Meaning, these frictional force depend on the angle that window has been installed as an entirety.
Because curve be tilted in less between A ' and B ' and at a B " and A " between bigger, it is possible at curve
II and III sees because what the function of brake unit 22 produced incrementally adjusts power.Therefore, incrementally adjusting of power has in pass
Close or nearly closed position (A ', A ") provides maximum braking effect and provides the system of progressive reduction under bigger open angle
The effect of dynamic effect.In other words, spring assembly the frictional force adjusted between sliding seat 16 and guide portion 18 of the power applied
Increase during reduction, therefore more constant combination braking effect is provided in the whole path of window.
Curve II shows the working curve of the spring assembly of the brake unit of being provided with 22, and wherein, angle [alpha] has been repaiied herein
Change about 90 ° into.Curve III shows the working curve of the spring assembly of the brake unit of being provided with 22, and wherein, angle [alpha] is of about
60°.It can be seen that both braking effect and hysteresis effect are the most notable in curve III.
Therefore, it can the requirement according to selected mounting condition and optimize hysteresis effect.Incline more greatly if window is arranged on to have
In the roof at angle, then the frictional force between sliding seat 16 and guide portion 18 is less in the nearly closed position of window.In this situation
Under, it is generally desirable to the brake unit with smaller angle α is set.And, on the contrary, in the situation on the roof with relatively small tilt angle
Under, the brake unit with larger angle α is set.
