Patent number: 11584459Abstract: The present invention relates to a drive unit in the form of a caravan mover (10) comprising a motor (12) (drive means) and a head (14) which are linked together by a gear mechanism (16). The head (14) provides a roller (15) which is rotatably mounted on a shaft. The roller (15) is arranged, in use, to be urged or pressed against the tread portion (surface) of a tyre. The drive unit is controlled by a control unit (ECU) which controls the movement of the driven roller (15) between the disengaged position and the engaged position and also controls the rotation (and direction) of the driven roller (15). The caravan mover (10) of the present invention includes an integral power supply such that the unit comprises a single integral system which is easily installed on the caravan and does not require the routing of cables from a remote power supply.Type: GrantFiled: February 1, 2019Date of Patent: February 21, 2023Assignee: Purple Line LimitedInventors: Jonathan Harrison, Ben Hawkins

Publication number: 20220081047Abstract: The present invention relates to an adjustable control system for a caravan moving system in which the caravan movers each include a brushed motor. The adjustable control system can control two caravan movers (10) mounted on a single axle caravan or two caravan movers mounted on a twin axle caravan or four caravan movers mounted on a twin axle caravan (quad system). The caravan moving system comprises a control unit, a user operated actuating device, power means and a drive unit. The present invention utilises a control system which provides variable movement of the or each caravan mover (10) and also provides gradual changes in both speed of each brushed motor and the subsequent ability to smoothly change the direction of travel of the caravan. In particular, the present invention enables the caravan to follow a wavy or curved line of travel in which the radius of the turn varies (i.e. from 0 degrees to a spin on the spot (equivalent to a 90 degree turn)).Type: ApplicationFiled: February 19, 2020Publication date: March 17, 2022Applicant: PURPLE LINE LIMITEDInventors: Ben Hawkins, Jonathan Harrison, Yuxian Tao

Publication number: 20210039732Abstract: The present invention relates to a trailer drive unit in the form of a caravan mover comprising a motor 16 (drive means/drive device), a head 14 housing a roller 20 which are linked together by a gear mechanism 22. Specifically, the present invention provides a support and drive transmission system 22 located centrally on the roller 20 with the roller 20 being provided by a first lateral portion/roller 19 and a second lateral portion/roller 21. In this arrangement, the length of the lateral roller 10 portions 19, 21 are individually shorter than a single roller such that the torque created in the central drive transmission portion is significantly less.Type: ApplicationFiled: February 1, 2019Publication date: February 11, 2021Applicant: PURPLE LINE LIMITEDInventors: Jonathan Harrison, Ben Hawkins
