Abstract

The invention comprises a clamping device which is part of an accessory which can be fitted on the tow hook of cars. The clamping device is pushed horizontally over the tow hook, and, by simply rotating one vertical bolt with a clamping cup downwards, the ball is clamped securely between the cup and the ring beneath it. The unit is designed in such a way that, when the bolt is tightened, the ball is approximately 3/4 enclosed, with the result that an optimum clamping effect is achieved with the 3 m/m play in the top of the cup and in the bottom of the ring. Furthermore, the clamping device is supported on the vertical section of the tow hook, specifically in such a way that the accessory, in the fitted position, cannot tilt away downwards or sideways. By pushing the supplied locking strip behind the ball and locking it with a padlock, it is virtually impossible to lose the accessory while driving, and the accessory also serves as an antitheft precaution.

Description

BETREFT: KLEMINRICHTING OP DE TREKHAAKKOGEL.SUBJECT: CLAMPING DEVICE ON THE TOWING BALL.

De uitvinding heeft betrekking op een kleminrichting van een hulpstuk dat op de trekhaakkogel van auto's kan worden gemonteerd.The invention relates to a clamping device of an attachment that can be mounted on the towing ball of cars.

Het hulpstuk is als accessoire eenvoudig te de- en monteren op de trekhaakkogel, en het dient als een basisdrager waarop toebehoren worden geplaatst zodat de drager dienst kan doen als; fietsdrager voor 2 fietsen, voor 3 fietsen, bagagedrager, skidrager en mogelijke andere toekomstige toepassingen.The accessory is easy to disassemble and assemble as an accessory on the tow ball, and it serves as a base carrier on which accessories are placed so that the carrier can serve as; bicycle carrier for 2 bicycles, for 3 bicycles, luggage carrier, ski carrier and possible other future applications.

De basisdrager heeft een opening aan de achterzijde in de vorm van de kogel en wordt horizontaal over de trekhaakkogel geschoven. De tolerantie bedraagt hier rondom 1 mm.The basic carrier has an opening at the rear in the shape of the ball and is slid horizontally over the towbar ball. The tolerance here is around 1 mm.

De bovenzijde van de trekhaakkogel (H) is nu geplaatst onder een taps toelopende cup (B) welke met een geborgde M8x20 bout (I) aan een M20x70 bout (metrisch fijn) (A) is bevestigd en wel zodanig dat de bout kan draaien in de gelaste M 20 moer (G) en de cup (B), die is voorzien van een aangelaste lip, in z'n geleiding wel mee op en neer gaat maar niet kan meedraaien.The top of the towbar ball (H) is now placed under a tapered cup (B) which is attached to an M20x70 bolt (metric fine) (A) with a captive M8x20 bolt (I), so that the bolt can rotate in the welded M 20 nut (G) and the cup (B), which is provided with a welded-on lip, does go up and down in its guide but cannot rotate.

Bij het naar beneden draaien van de bout met de cup (A+B), schuift deze zich klem op de kogel (H) en het geheel wordt in de vastgelaste afgedraaide onderliggende ring (C) ingeklemd, waarbij zowel aan de onderzijde in de ring (C) ais aan de bovenzijde in de cup (B) ca. 3 mm. speling is gehouden voor een optimale klemming.When turning the bolt down with the cup (A + B), it slides clamp onto the ball (H) and the assembly is clamped in the welded twisted underlying ring (C), with both in the ring at the bottom (C) ais about 3 mm at the top in the cup (B). clearance is maintained for optimal clamping.

Als beveiliging wordt aan de achterzijde, achter de trekhaakkogel (H) langs, een grendelstrip (E) geschoven met een voorziening voor het plaatsen van een hangslot. Hiermee voorkomt men diefstal en het is onmogelijk de drager door wat voor oorzaak dan ook te verliezen.As a safeguard, a locking strip (E) is slid behind the towbar ball (H) along with a provision for placing a padlock. This prevents theft and it is impossible to lose the carrier for whatever reason.

De uitvinding beoogt tevens een zeer consument-vriendelijk gebruik, want door het vast- of losdraaien van 1 bout kan men in zeer korte tijd de basisdrager plaatsen of weer loshalen en opbergen.The invention also aims at a very consumer-friendly use, because by tightening or loosening 1 bolt, the basic carrier can be placed or removed and stored in a very short time.

De solide en eenvoudige bevestiging kon tot stand komen doordat de plaatsing niet zoals gebruikelijk van bovenaf (vertikaal) geschiedt waardoor het moeilijk is een effektieve klemming te verkrijgen, maar horizontaal via de opening aan de achterzijde waar de trekhaakkogel (H) tussen de cup (B) en de konische ring (C) wordt ingeklemd.The solid and simple attachment was achieved because the installation is not done as usual from above (vertical), making it difficult to obtain an effective clamping, but horizontally through the opening at the rear where the tow ball (H) between the cup (B) ) and the conical ring (C) is clamped.

Hiermee is bereikt dat meer dan 3/4 van de trekhaakkogel (H) omsloten is.This ensures that more than 3/4 of the towing ball (H) is enclosed.

Verder is de kleminrichting van de basisdrager zo gekonstrueerd dat hij zijn steun vindt aan het vertikale deel van de trekhaakstang (F) direkt onder de kogel met als gevolg dat hij nooit voorover kan kantelen wat veel schade kan veroorzaken aan het hulpstuk en op de basisdrager bevestigde goederen.Furthermore, the clamping device of the basic carrier is constructed in such a way that it finds its support on the vertical part of the tow bar (F) directly under the ball, as a result of which it can never tilt forward, which can cause a lot of damage to the attachment and is fixed on the basic carrier goods.
