Abstract
The invention relates to an adaptable frame carrier with triaxial freedom of movement for couches and seats, in which the freedom of movement is achieved in the X-, Y- and Z-direction by a system of elements which can be moved relative to one another and are spring loaded, a connecting element making the moveability between the X-, Y- and Z-direction interdependent. The invention is characterised in that the frame carrier having at least one dome-shaped rolling body (3, 8) which rolls along a pressure-resistant rolling plate (2) in the X- and Y-direction, and two cylinders (6, 7) which slide one into the other and are supported against each other in the Z-direction by a compression spring (4). One of the cylinders (7) which slide one into the other being connected in a spring-loaded and hinged manner to the frame (18) of the couch or seat via a frame connection plate (13).
Description
The present invention relates to the adaptable frame that is used for bedding and thing to sit on three-dimensional freedom of movement, swing frame of reinforcing on structure of these best a plurality of scaffold supportings and scaffold are by realizing by movable mutually element, to guarantee the activity on horizontal plane X-Y, in the dependence that realizes producing wobble deviation between horizontal plane and the vertical axis on the vertical axis by the appointment spring-loaded of linearity, make confirmable oscillatory forces only to occur by the interlocking of Connection Element.
The oscillation system that freely swings according to DE 43 00425 C2 constitutes oscillating bed, and oscillating bed supports by so-called swinging mounting basically.Main bearing position between horizontal plane and the vertical axis is realized by so-called slip cushion in this structure.The swing equilibrium of forces is to realize by the leverage that a complexity is set.Especially the cushion that slides supporting infall makes the functional flexible material that depends on the slip cushion, and the slip cushion should be set up a friction free bearing position.When being connected, the support plate of that described substrate and swinging mounting and slip cushion elements can produce very difficult problem here, in addition because bearing position should be in the inner firm connection that constitutes on the dynamics of oscillation system, the slip cushion elements must be born the standalone feature of a variety of complexity, and the cushion that therefore slides be I believe to such an extent that regard technical extremely complicated parts as.
The frictional force that additional crossover location between each element of leverage and the movable axis parts may occur adding according to DE 43 00425, this frictional force will produce tangible negative influence to oscillation system.
Other structure of the system that freely swings is for known to the public, but these structures do not provide the equivalent solution (for example US 25 29 639) of the swinging mounting that has the three-dimensional freedom of movement under the whole oscillation system situation that rubs less.
Therefore task of the present invention is, realizes the scaffold of a three-dimensional freedom of movement, and this scaffold has improved the friction supporting-point, and simplifies the somewhat complex design of said structure form and improve functional thus.
This task is solved by the feature of claim 1.Claim 2 to 5 has provided other practical structure.
Set forth the present invention by accompanying drawing according to three embodiment.Be illustrated as:
Fig. 1 be the three-dimensional freedom of movement and on the Z axle adaptable frame of external spring,
Fig. 2 is the scaffold with universal joint supporting structure,
Fig. 3 is the scaffold of built-in spring on the Z axle.
Realize that by hemispheric rolling element 3 and 8 friction that rolling element can be very little is rolled according to the free degree of Fig. 1 on the horizontal anomalous movement face X-Y that plays a decisive role on withstand voltage rolling plate 2.Rolling plate 2 is fixed on the support plate 1.Hemispherical rolling bearing is characterised in that, as the rolling radius R1 of selected hemispherical rolling bearing point the time, cause lift H1 on Z-direction in the X of scaffold or the skew on the Y direction by scaffold much larger than the semicircle radius R 2 of whole inner rolling element.Therefore this lift H1 can be based upon X with the dimension scale that depends on radius R 1 and R2 to the skew effect that makes progress with Y.This structure causes kinematic dynamic effect, produces potential energy by the skew on horizontal plane by swing frame structure 18 rising lift H1, and this energy plays a positive role for the wobble deviation of coordinating in whole oscillation system as the swing pulse.
Guiding on the Z axle constitutes linear steering by two cylindrical sleeve 6,7 of sliding mutually, it is characterized by, and spring element 4 (Fig. 1) can be realized mobile distance on this axle, because sliding bearing makes cylindrical sleeve 6,7 have less frictional resistance.For the peak excursion that cushions on the Z axle is provided with a buffering ring 15.
The support plate 1 of bottom is connected with the hemispherical rolling element 3 of bottom by a flexibly mounted support plate 5.Keep freedom of movement at this bearing position thus.On support plate 1, place a swing buffering ring 14.
The simple coupling assembling 12 that is made of the spring element 9 that is hinged on respectively on framework joint 10 and the adjustable pin joint is used for swing lift on horizontal-shift and the Z axle with oscillatory forces interrelatedly.Can realize thus, strong swing does not appear in the whole oscillation system of being made up of a plurality of separate support frameworks, scaffold firmly is connected by the scaffold of reinforcing on framework connecting plate 13 and the structure 18, because the skew in home position has been played the effect that cushions by coupling assembling 12, so coupling assembling helps swing stability simultaneously.This coupling assembling 12 is made adjustable (for example changing spring force), scaffold can be mated with whole oscillation system, promptly change oscillatory forces by adjusting.
Hemispherical rolling element 8 on top has a backstop 11, this backstop from the mechanism's upper limit system full swing lift that may occur.
Solved friction supporting-point problem according to said apparatus of the present invention, thereby be associated by the technical effect of the rising of scaffold on the Z of level axle with the coupling of swing energy, the power pulse that this effect passes through to be occurred should help swing stability.Satisfy in the desired function of supporting-point minimum friction forces under the situation of the processing rational structure of Z axle supporting member and the simple function of coupling assembling 12 on confining force learns a skill and realize desired swing stability.The conversion of structural design that meets the product of market demands can not cause difficulty to being processed into technical feasible element certainly,
According to the embodiment of Fig. 2, have universal joint supporting 16 on above-mentioned hemispherical rolling element 3 next doors, this universal joint supporting is finished described function embodiment illustrated in fig. 1 with the coupling assembling 17 that is positioned at the center basically.
And then also be fine according to the form of implementation among Fig. 3, on the Z axle, have a built-in spring element 4 in this embodiment, and can realize the function described in Fig. 1 embodiment equally.
