Abstract

A trolley/buggy comprises a handle bar locking system that allows handle bars 33 to be pivoted from position which enables a person to use the trolley/buggy sitting or standing (figs 1 and 2) to another position that permits operation of the trolley/buggy while the person is walking (fig 3). The locking system is operated by a knob 41 which pulls on a rod (36, fig 16) that releases a bolt (37) which locks in holes (64 or 65). Electric motors 53 are controlled by the throttle 43 which is connected to electronics in a box 6 which in turn is connected to two batteries (52). The whole unit can easily be taken apart for transportation for example in a car boot etc, by removing bolts or pins (63) wing nut (67) wing nut (45). The trolley/ buggy can carry one person and a golf bag with an umbrella.

Description

This invention relates to an electric golf buggy! trolley or can be used for other purposes such as mobility. It can be sat on, stood on or walked behind.

(Fig 16) Is the side view of handle bars and control with unique locking mechanism. The forks (35) slide over the housing (26) and is connected by bolt and wing nut (45). This allows the whole of the handle bars and controls to move backwards and forwards. The unit is controlled by a unique locking mechanism.

The knob (41) is pulled up via a rod (36) which connected to a locking bolt (37) this travels through a tube (40) which is welded to the handle bar strut (34) a spring (39) returns the bolt (37) to holes (64 or 65) whether the operator wishes to stand, sit or walk. The throttle control (43) is connected via wire (46) which is threaded through handle bar strut (34) and the connector (47) plugs into box (6) through socket (11). Removal of the bolt and wing nut (45) allows the whole of the handle bar unit to be removed for transportation (car boot etc) (Fig 17) exploded view of locking bolt mechanism (Fig 18) rear view (Fig 19) removable seat (58) with adjustor and post (59) which slides into (2) on chassis it has a notch at the bottom of the seat post which is located onto the split pin (66) to stop the seat revolving.

(Fig 20) Is the top view of the buggy/trolley without golf bag showing plan of the stand up and seating position. The whole unit is driven by two electric motors (53) which are connected to two gear boxes (54) which drive the rear wheels (55) and is controlled by the electronics box (6) the switch (49) has three positions, two forward and one reverse. The speed in first gear position is 4mph approximately, and is approximately 8mph in second gear. The reverse emits a beeping noise as a warning.

There are two batteries (12) which easily complete 36 holes of golf.

Claims

Claims.1. A trolley! buggy compromising of a ladder chassis which houses the two batteries, two electric motors and the gearboxes. Two rear wheels that are driven by the electric motors through the gearbox which is controlled by the solid state electronics a foot plate which enables the operator to stand and also a removable seat which enables the operator to sit.
2. The trolleys! buggy's steering system and front wheel connects to the chassis as in claim 1 via tubing which is inserted into the chassis and is fastened by two bolts or pins
3. The throttle control is situated on the handle bars and the wire is threaded into the handle bar strut it is connected by a connector into the electronics box which is mounted on the chassis.
4. The locking system which is mounted underneath the handle bars claim (3) is connected to the handle bar strut via a fork which is welded to the handle bar strut and is connected via a bolt and wing nut to the housing for adjustable steering; this locking system is operated by pulling up the knob on the top of the handle bars. This in turn pulls on a rod which releases a bolt with return spring that locks into a hole so that the handle bar unit can be pivoted backwards into the walking position the pivoting and locking handlebar unit allows the operator to sit, stand or walk in one easy operation.
