Description
The present invention relates to a kind of stair lift drive system.Especially, the present invention relates to the stair lift that a kind of and smooth spill guide rail is combined.
Stair lift is known in the prior art, and the actuating device of application can have gear, tooth bar or friction drive device.Netherlands patent applications NL2005398 such as discloses a kind of stair lift friction drive device longitudinally guided, and wherein multiple roller engages with rail friction.But the guide rail used in these actuating devices has tooth or other sharp component, it forms potential danger to stair and/or stair lift user.In addition, the usage of the actuating device described in this patent is limited in straight line/longitudinal guide.
Although seem in logic to get rid of the projection on guide rail because there is shortcoming, but projection is necessary so far, and cannot promote along the level and smooth and guide rail naturally following stair profile according to the actuating device of prior art.
Therefore the object of the invention is overcome above-mentioned shortcoming or a kind of viable option is at least provided.
The present invention and then propose a kind of stair lift drive system, comprising: the guide rail extended along track, and described guide rail is at least provided with the recess or recess that extend on the direction tangent with guide rail; Frame parts, be provided with at least one group of wheel, wherein at least one wheel is bonded on guide rail in the female portion, wherein each wheel can pivot, described axle is basically perpendicular to the direction extension joining the guide rail recess of center line of guide rail from least one wheel wherein said to, and extends perpendicular to the direction tangent with guide rail direction; Driving engine, be used in wheels at least one, wherein a part for the running surface of the wheel mode of mating in the form at least engaging recesses, is characterized in that the cross-sectional plane of guide rail has essentially smooth shape.
In each frame parts, guide rail is bonded on so-called junction point by the result of tractive force.The S. A. that junction can rotate relative to installing component around it with frame parts overlaps substantially.For one, by the situation of drive wheel, S. A. intersects each other at junction point, and then will be connected with guide rail by drive wheel.Respect to one another two by the situation of drive wheel, junction overlaps substantially with the S. A. of its frame part.Thus when all wheels are driven, himself is not pulled getaway by frame parts.
Conduit center dant is darker, and when the difference driving stair lift between the length in the path of the bending and/or multiple wheel of wreath piece is less, this contributes to preventing or reducing dislocation and/or slide and/or wear and tear further.In addition, nearer by drive wheel distance guide rail line of centers, then can around perpendicular to their S. A.s and perpendicular to centerline tangent and the demand that rotates of the axis crossing with line of centers is lower to them.
Usually, guide rail will position near stair side, and the smooth form of its middle guide mainly focuses on not towards sharp wedge angle and the greasy tooth bar of stair lift user.Smooth surface such as can be defined as not having the surface that radius is less than the edge of 15mm or 10mm or 5mm.Therefore touching guide rail can be very safe during use and when stair lift is idle.Can manufacture smooth guide by forming recess in substantially cylindrical pipe, and it can be bent and be twisted into multiple bent angle, in order to form warp rail.The part that guide rail does not form recess at it keeps its initial diameter substantially, and therefore whole circumference can keep substantially identical.
Especially, guide rail can be designed such that its cross-sectional plane keeps its same angular orientation on whole track, but according to actuating device of the present invention still not too by the destruction of the torsion produced during manufacturing guide rail, because the distortion of guide rail and rotation can be overcome by the miscellaneous part of actuating device, as will be described.In the situation of one wheel pairs, two wheels should be made by being pressed against on guide rail.Multiple wheel can also be had or organize wheel more.Wheel can be arranged in same recess on side each other, but can also be arranged in two opposing concave toward each other, if there are two opposing concave in guide rail.At least one wheel be bonded in guide rail recess determines the angular orientation of framework around lead rail axis.This wheel does not need must by drive wheel.The advantage of two or more recess or recess is, can be implemented to more stable being coupled of guide rail equally on the hand of rotation around the direction tangent with guide rail.The quantity of wheel also need not be limited to or equal the quantity of recess in guide rail.
