Abstract

Movement of the column causes changes in a magnetic field, which are detected and used to control the vehicle. The column and the electrical system is described in parent NL 8002727, and the present patent offers an improved mechanical system by which the column is returned to the neutral position when released. The column, which can move up and down through a spherical pivot bearing and a bearing sleeve, must be pressed down before it can be operated. A spring, which encircles the column, is anchored in a flange on the lower end of the bearing sleeve and in a fixed flange further up the column. When the column is released, the spring, sleeve bearing and a curved bearing fixed to the control box force the column into the neutral position.

Description

-* -** *% -1- > D HO/wd/Applied.Electr. 3 Besturingshande1- * - ** *% -1-> D HO / wd / Applied.Electr. 3 Control Operation 1

De uitvinding betreft een besturingshandel, in het bijzonder voor toepassing bij een voertuig voor een gehandicapte, met een spoel voor het opwekken van een elektromagnetisch wisselveld, inductieve opnemers en een onder 5 naar een neutrale stand gerichte voorspanning staande, rond een draaipunt alzijdig zwenkbare bedieningsstaaf, die gekoppeld is met middelen voor het ongelijkmatig variëren van het veld.The invention relates to a control handle, in particular for use in a vehicle for a disabled person, with a coil for generating an electromagnetic alternating field, inductive sensors and a pre-tensioning rod which can be pivoted on all sides towards a neutral position, pivotable towards a neutral position, associated with means for unevenly varying the field.

Een dergelijke besturingshandel is bekend uit 10 de Nederlandse octrooiaanvrage 8002727.Such a control trade is known from Dutch patent application 8002727.

Het is bij besturingshandels van groot belang een terugstelkracht die de besturingshandel na het loslaten ervan weer nauwkeurig in de neutrale stand terugbrengt. Met name bij kontaktloze besturingshandels is dit van belang, aan-15 gezien dit de enige kracht is die op de handel wordt uitgeoefend. Tot nog toe heeft men veelal getracht door een evenwicht van, met name door veren opgewekte, krachten de gewenste naar de neutrale stand gerichte terugstelkracht te krijgen.It is very important in control shops to have a reset force that accurately returns the control handle to the neutral position after it is released. This is important in particular in contactless control trades, since this is the only force exerted on the trade. Heretofore, efforts have often been made to obtain the desired restoring force directed to the neutral position by an equilibrium of forces, particularly those generated by springs.

Dit heeft als bezwaar dat wanneer één van de veerkrachten 20 door slijtage of dergelijke in grootte verandert, het evenwicht niet meer is gewaarborgd.This has the drawback that if one of the spring forces 20 changes in size due to wear or the like, the balance is no longer guaranteed.

Da uitvinding beoogt voor dit probleem een oplossing te verschaffen. Dit wordt volgens de uitvinding bereikt doordat de bedieningsstaaf een rond de staaf aange-25 brachte, in langsrichting van de staaf verschuifbare lagerbus vertoont, welke met een hol oppervlaktedeel gelagerd is in een bolvormige lagerkom en welke lagerbus onder naar de lagerkora gerichte voorspanning staat, een en ander zodanig, dat bij het zwenken van de bedieningsstaaf de tegenkracht 30 toeneemt.The object of the invention is to provide a solution to this problem. This is achieved according to the invention in that the operating rod has a bearing sleeve which is arranged around the rod and which can slide in the longitudinal direction of the rod, which bearings have a hollow surface part in a spherical bearing cup and which bearing bush is under pretension directed towards the bearing core, a and other such that the counterforce 30 increases when the operating rod is pivoted.

Door deze constructie wordt bereikt dat bij het uit de neutrale stand bewegen van de bedieningsstaaf de lagerbus zich verplaatst langs de staaf doordat hij met het holle oppervlaktedeel beweegt langs de bolvormige lagerkora.This construction achieves that when the operating rod moves out of the neutral position the bearing bush moves along the rod because it moves with the hollow surface part along the spherical bearing cores.

35 Hierdoor wordt de voorspanning vergroot naar mate de bedieningsstaaf verder uit de neutrale stand bewogen wordt.This increases the preload as the control rod is moved further out of the neutral position.

De voorspanning wordt bij voorkeur geleverd door een tussen de lagerbus en een vast met de staaf verbonden flens opgesloten veer.The pretension is preferably provided by a spring enclosed between the bearing bush and a flange fixedly connected to the rod.

De uitvinding wordt aan de hand van het uit-5 voeringsvoorbeeld verduidelijkt.The invention is elucidated on the basis of the exemplary embodiment.

De tekening toont een gedeeltelijk doorsnede-:aanzicht van een besturingshandel volgens de uitvinding.The drawing shows a partial cross-sectional view of a control handle according to the invention.

Voor de werking van een dergelijke besturingshandel wordt verwezen ,>naar de eerder genoemde octrooiaanvrage 10 8002727.For the operation of such a control handle, reference is made to the aforementioned patent application 10 8002727.

De bedieningsstaaf 1 is verbonden met een bol scharnier 2 dat in een lager 3 alzijdig zwenkbaar is. In langsrichting van de bedieningsstaaf 1 is een lagerbus 4 verschuifbaar, welke met zijn holle oppervlaktedeel 5 15 afsteunt op een bolvormige lagerkom 6. Tussen het dwars op de bedieningsstaaf gerichte deel 7 van de lagerbus en de flens 8 is een veer opgesloten.The operating rod 1 is connected to a convex hinge 2 which can be pivoted on all sides in a bearing 3. A bearing bush 4 is slidable in the longitudinal direction of the operating rod 1, which bearing with its hollow surface part 5 rests on a spherical bearing cup 6. A spring is enclosed between the part 7 of the bearing bush oriented transversely to the operating rod.

De inrichting werkt als volgt. Bij het uit de neutrale stand bewegen van de bedieningsstaaf 1 beweegt de 20 lagerbus 4 met het holle oppervlakte-deel 5 daarvan langs' de bolvormige lagerkom 6 in, in de tekening gezien, opwaartse " richting. Daardoor zal de lagerbus 4 zich langs de staaf V in de tekening gezien, naar rechts bewegen. De veer 9 wordt derhalve samengedrukt en levert een tegenkracht welke toeneemt 25 met de mate van uitwijking vanuit de neutrale stand van de bedieningsstaaf 1. Deze kracht zal wanneer de bedieningsstaaf 1 wordt losgelaten deze weer naar de neutrale, in de tekening aangegeven stand terugbrengen.The device works as follows. When the operating rod 1 moves out of the neutral position, the bearing bush 4 with its hollow surface part 5 moves along the spherical bearing cup 6 in the upward direction seen in the drawing. As a result, the bearing bush 4 will move along the rod S, seen in the drawing, move to the right, therefore, the spring 9 is compressed and produces a counterforce which increases with the amount of deflection from the neutral position of the control rod 1. This force will, when the control rod 1 is released, return it to the return to the neutral position shown in the drawing.
