Abstract

Telescopic arrangement (1), especially a hydraulic (14) arrangement, and especially for system of furniture, but also for other systems or arrangements (1), which shall be lifted (4.1/11, 4.2/11) or lowered (12). It contains a coupled (3) double stroke (4.1, 4.2) arrangement of cylinders (5.1, 5.2). The respective stroke of these cylinders (5.1, 5.2) is directed opposite to each other (19.1, 19.2). The opposite directed strokes could ideally move along the same line.

Description

Telescopic arrangement with double stroke
The invention relates to a telescopic arrangement, especially hydraulic, and especially for system of furnitures, but also other systems or arrangments, which shall be lifted or lowered.
Hitherto have one by the system of elevating especially used of the branch of furnitures, where one especially have to had strokes as an example over 35 cm, with an elevating of weight as an example from 100 kg and over that, used solutions of mechanical screw-spindles . The disadvantage by this system is that it is very expensive, complicated and complexed to use.
Hitherto have one also establish elevating systems via hydraulic. Where one then have had one cylinder there in its self has the whole stroke. One of the disadvantage has here been that the lower minimum high has been limited, as the piston rod fully extended nessesary also must have an extra lenght of guiding/holding.
In the same time has the arrangement of pump for an syncron elevating or lifting, especially if it has been made as a pump-unit of magazine cylinders, been impossible to made compact both according to the thikness as according to the stroke. As then the pump unit on a furniture, almost will be impossible to place, because of now its outer extra nessesary larger size.
The system will morover also here be expensive to established.
The purpose with the invention is, to provide an arrangment for liftning or lowering of this in beginning mentioned sort or kind, where one obtain a relative long stroke, with a relative large stationary as dynamic activated lift, establish of/by one in itself compact embodyment or arrangement of elevating.
The new of the invention is that the telescopic arrangement 1 especially can contain of a coupled 3 double stroke 4.1 and 4.2 arrangment of cylinders 2. Where the one 5.1 of the compact cylinder arrange- ments 2 is turning opposite the other, and with a diametrically opposite directed stroke 4.1 as 4.2. And where the "stroke" 4.1 or 4.2 according to the direction of movement or the direction of operation 4.1 as 4.2 ideal for that matter generally has a line convergence.
With the new telescopic arrangement 1 according to the invention one can optain that one compact and very easy can establish one in itself generally self guided and leaded unit 2 out of area of the elevating. Generally with standard components as an example hydraulic cylinders 5.1 as 5.2. And where one by a bulding together 3 according the invention extend the area of function of thies standard components 5.1 and 5.2 to a double lenght of stroke 11 with generally the same possibility of loading or limit, as for one cylinder 5.1 or 5.2.
The telescopic arrangement 1 will especially be driven optimal, where one as an example use hydraulic. And where the system of pump 6 as an example is of the type magazine cylindres 7, which is couble toghter "as bundles" 8 and 9. And for that matter ideal has been force guided synchronic 18 in the stroke. As an example 2 cylinders 5.1 and 5.2 here in the same time 3 will be able to be driven or lifte 4.1 as lower 4.2 as an example a telecopic leg 10 or a like unit 10.
The invention shall after this be explain neare in the following according to the drawing, where
Fig.l shows, seen in a generally perspective a lifting/lowering system 5.1 and 5.2, where an arrangements of the hydraulic cylinder 5.1 as 5.2 is established respectively as telescopic leg 10. And where a pumping system 6 for that matter also a shown. As the telescopic arrangement 1 or elevating unit 1 here is made as 2 opposite pointing cylinders 5.1 as 5.2. Which in the telescopic arrangement 1 are coubled 3 "floating" together by the houses of the cylinders 5.1 and 5.2.
The stroke 4.1 and 4.2 of the arrangement 1 can be seen indirect as a "maximum-stroke" 11, as opposite as a "minimum-stroke" 12. As it clearly can be seen that the minimal high 12 "only" almost is limited of the high of the cylinder house 5.1 as 5.2. And if the 2 opposite pointing pressure cylindres 5.1 as 5.2 are builed together 3 in the same niveau or plan as shown on Fig.l, then will this establish an extrem low high of build 11.
An optimum example on a pumping arrangement 6 according to the invention is also shown in Fig. 1. As there here are shown a magazine system 7 containing of coubled and mutual forced guided 18 pumping cylinders 7.
For the shown arrangement 2 is used 2 cylinders, here indicated by its no. 5.1 as 5.2. As a forward conveying 8 as a backward conveying 9 in the house of the pump 6 respectively will course an syncron lifting 4.1/4.2 or 11 as lowering 17. Especially if the dimension of the cylinders in the pump 6 as at the telescopic arrangement 1 generally are the same. An ideal guiding or leading of the pipe-line 13 of the oil pressure pipe line 19 from/to each cylinder 5.1 as 5.2, will also ideal be able to be establish only as one pipe line 13 to/from each cylinder 5.1 as 5.2.
The pipe line 14 to/from lifting/lowering arrangement 1 to/form the pump arrangement 6 can be solid mounted or fixed to the telescopic arrangement 1. While thies 13 inside in the telescopic-arrangement 1, as the present embodyment shows, shall be made or mounted as flexieble and loose movable.
On the pumping arrangement itself 6 in Fig.l is shown an example on an activating arrangement 15. 16 and 18, here as a revolving handle 15. Where one then manual here shall turn 16 to activat the telescopic unit for lifting 4.1/4.2 as for lowering.
The system 1, 2 and 6 could also be establish motor driven.
Fig.2 shows an activated and moved telescopic arrangement 1, with a shown embodyment with an ideal placing of the comming supplying lines or pipes 14 in the top of the arrangement. And where the arrangement 1 for that matter is shown at its or under the maximum lenght of a stroke 11.
Fig.3 shows a compressed telescopic arrangement 1, in its minimal high of stroke 12.
The house of the telescope 1, contain of here as an example of 3 coubled and sliding shells or cases 17. Ideal made of aluminium, steel, plast or like. And where the cases 17 mutual are guided as an example via a covering of plast or like material of bearings.
