Summary of the invention
Therefore, technical problem to be solved by this invention is, provides a kind of patient's Height-adjustable of the above-mentioned type, although this patient's Height-adjustable manufacturing cost is relatively low, not only follows the minimum requirements of variant national regulation, and can not obviously exceed standard.
Above-mentioned technical problem is solved like this according to the present invention, namely, in patient's Height-adjustable of the above-mentioned type, described two leads are kept at a distance mutually by the distance pieces that substantially extends between these two leads along its whole height, and form described movable rod structure ingredient, be respectively equipped with at least one slide block substantially with the slip shell of halfliner shape and guide movement slidably at described lead.Therefore, especially significantly part of the present invention is: fixing rod structure has between two leads substantially along the distance pieces that its whole height extends.This continuous print distance pieces makes two leads keep predetermined distance along its whole axial extension, thus strictly limits the danger that lead is out of shape when bearing high load capacity.This achieve, because two leads are able to mutually strengthen continuously by above-mentioned continuous print distance pieces, so adopt relatively long and narrow (perhaps even tubular, that is hollow) lead, this achieve the cramped construction same with the version of low cost, at this, standardized component (such as piston rod) particularly will be adopted can to contribute to reducing costs significantly for lead as starting point.At this particularly advantageously: described distance pieces groove at side surface, described lead is arranged in the dead slot of distance pieces.This contributes in the meaning of fixing rod structure providing high strength, again fundamentally reaching the above-mentioned enhancing to two leads by distance pieces with alap cost.
In addition, salient point of the present invention is: slip shell has halfliner shape substantially.According to the corresponding layout of the one of slide block, slip shell laterally acts in both sides in this case and to be arranged on by two leads and at least one on unit that the distance pieces between lead forms.A constitutionally stable unit is formed according to above-mentioned thought by two leads and the distance pieces arranged between which, movable rod structure acts on described unit by means of the slip shell of mutually opposing halfliner shape in outside, in addition, in order to seamlessly support and guide described movable rod structure on fixing rod structure, utilizing the intrinsic elastic force of (make lead keep certain distance) distance pieces to a certain extent, is also feasible.Therefore also can realize accurately when adopting parts (such as lead and slip shell), seamlessly on fixing rod structure, guiding described movable rod structure, and described parts bear the tight tolerance more lower slightly than patient's Height-adjustable of known the above-mentioned type conventionally.Based on above-mentioned statics, that is owing to lead can be pressed in the dead slot elaborated of distance pieces above by halfliner formula in the transferable power of slip shell of both sides movement slidably on the rod structure fixed, therefore abandoned other connecting devices that may need.
Therefore, achieve according to project organization of the present invention, as can be seen from elaboration hereafter, even if when peak demand, (such as in intensity) adopts the standardized components of relatively economical viewed from different aspect in machinery or stability, can not lose lifting structure for operation vital precision and bearing capacity, in addition, also can design closely when needed according to the lifting structure of patient's Height-adjustable of the present invention.
Preferably expanding in design according to Section 1 of the present invention, particularly preferably be, each slide block is provided with the slip shell of two spaced distances vertically.This is conducive to lessly abrasively on fixing rod structure, guiding movable rod structure accurately.
In addition, particularly preferably be, described slip shell, by being axially fixed in described slide block in the bearing that is embedded into the reinforcement of slide block and along lead, reaches the axial restraint along both direction particularly by the step of the both sides in slide block or convex shoulder thus.Because this pure mechanical type is vertically fixed, described slip shell when needed (when movable rod structure is removed) can be changed easily.Anti-rotational fixing in the corresponding bearing that the slip shell of halfliner shape arranges in the correspondence of slide block, once need, realize by simple measure, such as, by the overlap joint plunger of steady pin.According to the most preferred scheme of one, described slip shell is riveted and/or is adhesively fixed on by (knockdown if desired) in described slide block.
The distance pieces of fixing rod structure advantageously can be designed to the form of solid distance plate in specific purposes, and wherein fixing on described distance plate of described lead especially can by fixedly realizing with pin in this case.And the typical apply for other particularly preferably is, according to another expansion design of the present invention, the distance pieces of described fixing rod structure is designed to extrudate that is box and/or that be provided with inner reinforcement, such as, be formed from aluminium.This distance pieces being designed to extrudate is optimum by thought described above in its intrinsic elasticity, so also can adapt to following requirement, that is, movable rod structure seamlessly moves under the effect of the pretightning force determined that is with the guiding on the construction unit comprising two leads and setting distance pieces between which of adhesive force as much as possible of slip shell on lead.
In addition, can realize in a straightforward manner by distance pieces being designed to extrudate, this distance pieces has the cavity be arranged between lead, and at least one linear actuator (such as hydraulic cylinder) of arranging corresponding to lifting drive is arranged in the cavity.Lifting drive can be acted in the plane determined by two leads in this way, and for the reason of stability, it is favourable for doing like this.Preferably, described extrudate has the side face substantially closed to the same reason for stability aspect.
