ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates generally to mower seats, and more specifically, to a lawn mower seat that reduces the transmission of vibrations from the mower to the operator.
DESCRIPTION OF THE RELATED ART
Various mower seat configurations have been developed to increase operator comfort and to reduce fatigue of the operator.
U.S. Pat. No. 3,572,816 discloses an arcuate seat for riding implements, which extends transversely to the direction of travel of the implement, whereby a rider may change sitting positions along the seat when the implement moves over a non-horizontal surface.
U.S. Pat. No. 4,930,593 discloses a pivoting seat structure for a front mounted mower that includes a main support plate pivotally connected to the lower frame for rotation about a first transverse axis and a seat including a mounting plate connected to the support plate for rotation about a second transverse axis offset in the fore-and-aft direction from the first axis.
These prior art devices typically use damping devices between the seat and the mower. However, these devices still have points of contact between the seat and the mower frame, which directly transmit mower vibrations. Accordingly, there is a need for an improved mower seat, which eliminates direct contact between the seat and the mower frame so that the vibration can be dampened before received by the seat. Further, there is a need for the improved mower seat that is simple in design and inexpensive to produce.
SUMMARY OF THE INVENTION
The object of this invention is to provide an anti-vibration seat for a riding mower.
More specifically, the invention is directed towards an anti-vibration seat including a bracket, seat frame and isolators.
According to the invention, the bracket is fixedly attached to the mower frame. The seat frame is pivotally and slidably attached to the bracket so that the seat frame is vertically separated from the bracket when the seat frame is in a sitting position.
In accordance with an embodiment of the invention, the isolators have a lower end fixedly attached to the mower frame and an upper frame engageable with the seat frame.
It is therefore an aspect of the present invention to provide more comfort to the operator by reducing the vibration in the seat.
It is yet a further aspect of the present invention to provide a seat frame that floats in pivot slots and rests on isolators rather than the seat frame being mounted directly to the mower frame.
These and other aspects of this invention are illustrated in the accompanying drawings, and are more fully disclosed in the following specification.
