Description
- This invention relates to a golf trolley, and more especially, this invention relates to a battery powered golf trolley.
- The game of golf is extremely popular. The golf clubs required to play the game are heavy and many golfers prefer to take their golf clubs around a golf course using a golf trolley. These golfers who prefer to use a golf trolley include elderly persons, and persons who simply find the effort of carrying a golf bag around a golf course too strenuous for comfort.
- A problem with golf trollies is that they can damage golf courses in wet conditions. More specifically, the wheels of golf trollies can quickly damage grass, especially if there has been prolonged rain. Grass areas can quickly be turned into areas of mud. In view of the damage caused by golf trollies, they are often not allowed on golf courses in wet conditions. This means that person needing to use a golf trolley are often prevented from playing golf due to wet conditions. Since wet conditions are usually present throughout the winter, it is not unusual for such golfers to be prevented from playing golf throughout the entire winter.
- It is an aim of the present invention to obviate or reduce the above mentioned problem.
- Accordingly, in one non-limiting embodiment of the present invention there is provided a golf trolley comprising a handle, a frame, and a battery-powered drive arrangement, the battery-powered drive arrangement comprising a pair of drive members which each comprises an endless track, drive means for driving the track, and support means for supporting the track such that a portion of the track is flat for engaging the ground and moving over the ground without damaging the ground.
- The use of the track enables the golf trolley to be used in wet conditions without damaging golf courses, for example the fairways of golf courses. In addition, the use of the track enables the golf trolley to achieve more traction on hilly or rough terrain that would otherwise be the case if the golf trolley just had wheels. Thus the golf trolley of the present invention is firstly advantageous in that it is able to be used in inclement weather conditions and thus enables golfers requiring a golf trolley to be able to play golf all the year around. The golf trolley is secondly advantageous in that it provides more traction on hilly or rough terrain, which helps the golfers to get around golf courses.
- The golf trolley may be one in which the support means comprises a plurality of support wheels. Preferably there are three of the support wheels. More or less than three of the support wheels may however be employed.
- The support wheels may be not directly driven support wheels.
- With support wheels which are not directly driven, each drive members may include a single drive wheel which engages the inside of the track and thereby drives the track.
- Alternatively, each drive member may include a drive wheel which drives at least one planet wheel, the planet wheel contacting and driving an adjacent one of the not directly driven support wheels. With such an arrangement, there may be one of the planet wheels. Alternatively, there may be three of the planet wheels. Any suitable and desired number of planet wheels may be employed.
- The golf trolley may alternatively be one in which the support wheels are directly driven support wheels.
- In all embodiments of the invention, the trolley may be one in which the support means includes at least one longitudinally extending support member for facilitating keeping the track flat.
- In the embodiment of the invention where the support means comprises the plurality of support wheels, then there may be one of the longitudinally extending support members positioned between each pair of the support wheels.
- The battery-powered drive arrangement may include any suitable and appropriate drive train for providing drive from one or more batteries to the drive members. Thus, for example, the battery-operated drive arrangement may include a clutch for engaging and dis-engaging the drive means.
- Advantageously, the frame may include a step portion for receiving a golf bag.
- The golf trolley will normally include a front wheel mounted on the frame, the front wheel being for resting on the ground when the golf trolley is standing up and at rest.
- The golf trolley of the present invention may be such that it is used with normal wheels in the summer and other periods when the ground is sufficiently dry, and with drive members including the endless track in winter and other periods when the ground is too wet for use by known golf trollies having simple wheels. In order to facilitate changing a golf trolley from a summer drive arrangement including normal wheels, to a winter drive arrangement including the track, the golf trolley of the present invention is advantageously such that each one of the drive members is secured with respect to the frame by a quick-release arrangement. Any suitable and appropriate quick-release arrangement may be employed including nuts with integral wing members for enabling the nuts easily to be removed by hand.
- The golf trolley may include pivot means for enabling the drive members to pivot. When pivot means are employed, the drive members may pivot completely through 360°, or they may be constrained to pivot through less than 360°, for example 90° or 180°.
- The golf trolley of the present invention may include at least one battery.
- Generally, the golf trolley of the present invention may be manufactured to any suitable and desired design and size. The track may be of any desired length and width. Typically, the track will be 100-150 mm wide and 300-400 mm long. Generally, the length of track employed may be that designed to cause the track to have an outer general peripheral shape giving its drive member the approximate size of a known golf trolley wheel. The track may be made of any suitable and appropriate materials. A combination of a plastics material and a rubber material is presently preferred. The support means for supporting the track are preferably made of plastics materials but other materials may be employed if desired.
