Height-adjustable upright tube-cage unit

Abstract

A height-adjustable upright tube-cage unit comprising a telescopic cage which comprises an inner cage and an outer cage, and a telescopic upright tube which comprises an inner upright tube and an outer upright tube and is accommodated in the cage, wherein the elements inner cage, outer cage, inner upright tube, and outer upright tube can be connected to each other via a shared, telescopic scaffolding, wherein the scaffolding is adjustable between a first detent position, in which the inner cage is latched with the outer cage and the inner upright tube is latched with the outer upright tube, wherein the upright tube is longitudinally displaceable within the cage, and a second detent position, in which an upper cage part is latched with an upper upright tube part, and a lower cage part is latched with a lower upright tube part.

1 . A height-adjustable upright tube-cage unit comprising:
 a telescopic cage which comprises an inner cage and an outer cage; and   a telescopic upright tube which comprises an inner upright tube and   an outer upright tube and is accommodated in the telescopic cage,   wherein the inner cage, outer cage, inner upright tube, and outer upright tube can be connected to each other via a shared, telescopic scaffolding, wherein the scaffolding is adjustable between a first detent position and a second detent position,   wherein, in the first detent position, the inner cage is latched with the outer cage and the inner upright tube is latched with the outer upright tube, and wherein the upright tube is longitudinally displaceable within the cage, and in which in the second detent position, an upper cage part is latched with an upper upright tube part, and a lower cage part is latched with a lower upright tube part.   
     
     
         2 . The height-adjustable upright tube-cage unit of  claim 1 , wherein the scaffolding comprises a telescopic rotary shaft which operates detent sliders provided for latching the inner cage, outer cage, inner upright tube, and outer upright tube, wherein the rotary shaft comprises actuator levers which engage into slotted links assigned to the detent sliders in order to actuate the detent sliders. 
     
     
         3 . The height-adjustable upright tube-cage unit of  claim 2 , wherein the detent sliders comprises a first detent slider and the first detent slider is secured on the outer upright tube and, in the first detent position, fastens the outer upright tube to the inner upright tube and, in the second detent position, releases this fastening. 
     
     
         4 . The height-adjustable upright tube-cage unit of  claim 2 , wherein the detent sliders comprises a second detent slider and the second detent slider is secured on the inner cage and, in the first detent position, fastens it to the outer cage, and, in the second detent position, fastens the inner cage to the lower upright tube part while releasing the connection to the outer cage. 
     
     
         5 . The height-adjustable upright tube-cage unit of  claim 4 , wherein the lower upright tube part is the outer upright tube. 
     
     
         6 . The height-adjustable upright tube-cage unit of  claim 2 , wherein the detent sliders comprises a third detent slider and the third detent slider is secured on the outer cage and, in the second detent position, fastens it to the upper upright tube part and, in the first detent position, releases this fastening. 
     
     
         7 . The height-adjustable upright tube-cage unit of  claim 6 , wherein the upper upright tube part is the inner upright tube. 
     
     
         8 . The height-adjustable upright tube-cage unit of  claim 1 , wherein the scaffolding provides a third detent position which is reachable from the first detent position and which actuates a fourth detent slider without influencing other detent sliders, in order to release a connection of a basin element to a base of the lower cage part. 
     
     
         9 . The height-adjustable upright tube-cage unit of  claim 1 , wherein at least individual detent sliders are preloaded detent clamps which engage around an outer element while engaging into a slotted link and, in an open position, engage into a detent groove of the outer element and, during the transition into a closed position, advance into a detent groove of an inner element which is congruent with the detent groove of the outer element. 
     
     
         10 . The height-adjustable upright tube-cage unit of  claim 1 , wherein at least individual detent sliders comprise hook elements which engage into abutments, provided therefor, of an element to be fastened.
