Abstract
Abstract There is disclosed a monorail transport apparatus for transport of golf equipment in golf links, comprising a transport vehicle body provided with a caster wheel rollable on a monorail, a driving vehicle body equipped with a prime mover and partly received in and pivotally connected to the front portion of the transport vehicle body so as to be swingable around the axis of a transverse shaft, a driving wheel and a driven wheel disposed on both sides of the transverse shaft, an endless driving belt entrained around the driving and driven wheels and pressed against the upper surface of the monorail, and an auxiliary wheel pivotally connected to the driving vehicle body so as to be swingable around the axis of the transverse shaft and pressed against the lower surface of the monorail, the arrangement being such that the transport apparatus travels while holding the monorail from above and below between said driving belt and the auxiliary wheel, thereby achieving increased hill climbing ability and increased traveling stability irrespective of the sinuousity of the monorail.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
159 words
A monorail transport apparatus comprising a transport vehicle body provided with a caster wheel rollable on a monorail having upper and lower surfaces, a driving vehicle body partly received in and pivotally connected to the front portion of said transport vehicle body so as to be swingable around the axis of a transverse shaft, a driving wheel and a driven wheel disposed on opposite sides of said transverse shaft, an endless driving belt entrained around said driving and driven wheels and pressed against the upper surface of said monorail, and an auxiliary wheel pivotally connected to said driving vehicle body so as to be swingable around the axis of said transverse shaft and pressed against the lower surface of the monorail, the arrangement being such that the monorail transport apparatus is propelled along the monorail by means of the driving vehicle body which engages the monorail from above and below between said endless driving belt and said auxiliary wheel.
Claim 2
Dependent Claim
159 words
A monorail transport apparatus comprising a transport vehicle body provided with a caster wheel rollable on a monorail having upper and lower surfaces, a driving vehicle body partly received in and pivotally connected to the front portion of said transport vehicle body so as to be swingable around the axis of a transverse shaft, a driving wheel and a driven wheel disposed on opposite sides of said transverse shaft, an endless driving belt entrained around said driving and driven wheels and pressed against the upper surface of said monorail, and an auxiliary wheel pivotally connected to said driving vehicle body so as to be swingable around the axis of said transverse shaft and pressed against the lower surface of the monorail, the arrangement being such that the monorail transport apparatus is propelled along the monorail by means of the driving vehicle body which engages the monorail from above and below between said endless driving belt and said auxiliary wheel.
Claim 3
Dependent Claim
47 words
A monorail transport apparatus as set forth in claim 1, wherein when the driving and driven wheels are pivotally connected to the driving vehicle body, the driving and driven wheels are disposed on opposite sides of and symmetrically with respect to the axis of the transverse shaft.
Claim 4
Dependent Claim
71 words
A monorail transport apparatus as set forth in claim 1, wherein when the endless driving belt is entrained around the driving and driven wheels, the driving and driven wheels are provided with meshing portions in the form of corrugations and endless driving belt is also provided with a meshing portion in the form of corrugations adapted to mesh therewith, so that the endless driving belt is rotated through such meshing construction
Claim 5
Dependent Claim
80 words
A monorail transport apparatus as set forth in claim 1, wherein, wherein when the auxiliary wheel is connected to the driving vehicle body so as to be swingable around the axis of the transverse shaft, there is provided a support lever suspended from one end of the transverse shaft for pivotally mounting the auxiliary wheel at the lower end of said support lever and said auxiliary wheel is pressed against the lower surface of the monorail by a compression spring.
Claim 6
Dependent Claim
143 words
A monorail transport apparatus as set forth in claim 4, wherein the auxiliary wheel arrangement consists of a front auxiliary wheel pivotally mounted at one end of a swingable front support lever suspended from one end of the transverse shaft and a rear auxiliary wheel pivotally mounted at the lower end of a swingable rear support lever pivotally suspended from the transport vehicle body through a second transverse shaft, a pressing rod is pivotally connected to one of said front and rear support levers, said pressing rod being inserted in a retainer pivotally connected to the other support lever, the inserted end portion of said pressing rod being formed with a threaded region, and a compression spring is disposed between a nut threadedly fitted over said threaded region and said retainer, thereby pressing the auxiliary wheels against the lower surface of the monorail.
