AI Technical Summary

Benefits of technology

This design reduces the risk of user injuries and trolley stranding by minimizing transverse forces, enabling safer operation and potentially allowing for increased load capacities while reducing the trolley's weight and cost.

Problems solved by technology

This may result in injuries, such as whiplash injuries due to sudden deceleration, to the users.
Further, the users may become stranded on the rails due to stopped trolleys, thereby requiring rescuing.
Furthermore, following trolleys may collide with the stopped trolleys, also resulting in injuries.
Increasing gradients of the rails, to reduce braking due to binding, otherwise increases speeds of the trolleys, which is contrary to a need to improve safety.

Embodiment Construction

[0010]According to the present invention there is provided a trolley, as set forth in the appended claims. Also provided is a rail assembly and a kit of parts for a rail assembly. Other features of the invention will be apparent from the dependent claims, and the description that follows.

[0011]According to a first aspect, there is provided a trolley for a rail, the trolley comprising:

a frame;

a set of wheels, including a first wheel and a second wheel, rotatably coupled to the frame; and

an attachment member, coupled to the frame, for attachment, preferably suspension, of a load therefrom, in use;

wherein the first wheel is rotatable in a first plane about a first axis and the second wheel is rotatable in a second plane about a second axis;

wherein the first plane and the second plane define a line;

wherein the trolley is arrangeable in:

a first configuration, wherein the attachment member is arranged at a first angular displacement about the line; and

a second configuration, wherein the a...

Abstract

A trolley 100 for a rail 10 is described. The trolley 100 comprises a frame 110, a set S of wheels 120, including a first wheel 120A and a second wheel 120B, rotatably coupled to the frame 110 and an attachment member 130, coupled to the frame 110, for suspension of a load W therefrom, in use. The first wheel 120A is rotatable in a first plane P1 about a first axis A1 and the second wheel 120B is rotatable in a second plane P2 about a second axis A2. The first plane P1 and the second plane P2 define a line L. The trolley 100 is arrangeable in a first configuration, wherein the attachment member 130 is arranged at a first angular displacement D1 about the line L. The trolley 100 is arrangeable in a second configuration, wherein the attachment member 130 is arranged at a second angular displacement D2 about the line L, wherein the first angular displacement D1 and the second angular displacement D2 are different. A rail assembly 1, including the trolley 100 and the rail 10, is also described.

Description

FIELD[0001]The present invention relates to trolleys for rails and to rail assemblies including rails and such trolleys.BACKGROUND TO THE INVENTION[0002]Typically, a zipline (also known as a zip-line, zip wire, aerial runway or aerial ropeslide) comprises an inclined cable, secured only at upper and lower ends thereof, and a trolley (also known as a bogey), including a freely-rolling pulley. A user (i.e. a load), suspended from the trolley, may be accelerated by gravity from the upper end to the lower end of the inclined cable. In use, the pulley rolls along an uppermost portion of the inclined cable. A gradient of the inclined cable is typically in a range from 1 in 20 to 1 in 30. Usually, the inclined cable sags and appropriate tensioning of the inclined cable is required to control acceleration of the user. Since the inclined cable is secured only at the upper and the lower ends thereof, the inclined cable is restricted to a linear path, without lateral deviations, such as curves...
