DESCRIPTION:
BRIEF SUMMARY
This invention relates to a mounting bracket. In particular though not exclusively this invention relates to a mounting bracket for a winch. The winch can be a powered winch or can be a hand operated winch eg ratchet operated.
Winches which are driven by electric motors drawing power from a vehicle battery have to be secured to a vehicle in order for the winch to operate in an effective and convenient manner.
Winches used in this way can be operated to haul loads for example un-powered wheeled vehicles and logs. It is necessary that the line of draw of the winch can be varied without the need for continuous re-positioning of the vehicle on which the winch is mounted. It follows that the winch must be able to move relative to the vehicle depending on the relative positions of the vehicle and the load to be pulled by the winch.
The present invention seeks to provide a mounting bracket particularly for a winch which enables the winch to be easily secured on the vehicle and which allows the winch to swing relative to the vehicle.
The present invention further seeks to provide a mounting bracket particularly for a winch which can be conveniently attached to a vehicle by means of a ball hitch, a pin or a ball pin which are attached to the vehicle.
Accordingly the present invention provides a mounting bracket comprising a base, attachment means for loosely attaching the base to a support, and means allowing the base to move relative to the support.
The attachment means can comprise an opening in the base.
The support means can comprise a ball hitch, a pin hitch or a pin hitch terminating in a ball.
The means allowing the base to move relative to the support can comprise a tongue plate secured to the base engagable with the mouth of a guide plate secured to the ball hitch.
The mouth can include a recess in which one end of the guide plate is engagable.
The guide means can comprise a guide plate having a mouth engagable with a pin.
The base can conveniently include a carrying handle.
The attachment means can also comprise a first housing attached to the base and a second housing slidaly located within the first housing, the support being locatable within an opening in the second housing.
The first and second housings can include locating means to locate and guide the movement of the second housing with respect to the first housing.
The locating means can comprise at least one pin mounted on the second housing engagable in a slot formed in the first housing.
Alternatively the locating means can comprise a slot formed in the second housing engagable with the projection provided on the first housing.
In a further arrangement the attachment means can comprise a biased hinged latching mechanism.
The latching mechanism can comprise a spring loaded plated hinged to the base, the plate having an arcuate recess at its free end, the free end being locatable under a support whilst the support is positioned within a housing on the base.
The first housing can include a lip to assist in preventing the detachment of the bracket from the support.
The mounting bracket can be provided with a ball mounting.
The present invention further provides a winch secured to the bracket, the winch either comprising a power winch or a manually operated winch.
The present invention will now be more particularly described with reference to the accompanying drawings in which;
FIG. 1 shows a side elevation of one form of mounting bracket according to the present invention;
FIG. 2 shows a plan view of the mounting bracket shown in FIG. 1;
FIG. 3 shows an end elevation of the mounting bracket shown in FIGS. 1 and 2;
