Seat System for a Bass Boat or the Like
A seat for a fishing or bass boat can be raised or lowered by an operator. The elevation mechanism preferably includes a power mechanism to operate a screw jack and the power mechanism may be battery powered, hydraulically powered, or operated by other power-assist means. The screw jack enables the seat to be raised to approximately twice its retracted height.
This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/767,329 filed Mar. 18, 2006.
FIELD OF THE INVENTIONThe present invention relates generally to the field of seats installed in fishing boats and, more particularly, to a power pedestal mounting for a bass boat seat so that the seat can be raised and lowered.
BACKGROUND OF THE INVENTIONPleasure boats such as fishing or bass boats are typically equipped with one or more swiveling seats. Such swiveling seats are mounted in a recessed hole or base in the raised deck of the boat. The seats thus provide a somewhat raised position for the angler who wants a better view of what is going on below the surface of the water.
However, in most cases, the height of the boat seat is fixed, and thus does not afford an adequate view for the average fisherman. Consequently, the angler usually has to stand up to get a satisfactory view, or even climb up on a stepladder or similar structure, to get a better view. This kind of activity is at best inconvenient and at worst dangerous to the fisherman and to others in the boat with him.
Thus, there remains a need to a bass boat seat that can be raised or lowered by the fisherman at his desire to afford a better view of his surroundings, including the activity below the surface in the immediate vicinity of the boat. The present invention is directed to fulfilling this need in the art.
SUMMARY OF THE INVENTIONThe present invention provides a seat for a fishing or bass boat that can be raised or lowered by an operator. The elevation mechanism preferably includes a power mechanism to operate a screw jack and the power mechanism may be battery powered, hydraulically powered, or operated by other power-assist means. The screw jack enables the seat to be raised to approximately twice its retracted height.
The present invention further includes a foot rest or platform which is mechanically coupled to the seat and to the back of the boat seat, so that the foot rest rises and falls with the boat seat. The screw jack to raise and lower the seat/foot platform assembly includes a control mechanism that may be hand-held or foot-operated so that the seat can be controlled remotely, if desired.
These and other features and advantages of the present invention will be readily apparent to those of skill in the art from a review of the following detailed description.
In
The outer post 16 is slidably positioned over the inner post 14 and is equipped with a longitudinal slot 24. A pin 26 is attached to the inner post 14 and rides in the slot 24 of the outer post 16, thus allowing the outer post 16 to slide up and down but preventing it from rotating on the inner post 14.
Slip rings 15 are mounted on the top outer surface of the inner post 14 and ride on the inside surface of the outer post 16 to reduce friction between the two posts as the seat 60 is run up and down. The top of the inner post 14 defines a cap 19 with a hole 21 through it. A screw or spindle 28 extends through the hole 21 and runs up to a gear box 30 of a worm gear that is driven by a prime mover 32, described hereinafter as a motor 32, although the primer mover may also be a hydraulic or pneumatic power source, or even a manually operated prime mover. A nut 34, which is threadedly engaged with the screw 28, is mounted onto the upper end of inner post 14.
A motor 32 and a gear box 30 are mounted between a motor mounting plate 38 and a hold down plate 36. The plates 36 and 38 are joined together by bolts 40 and serve to clamp the motor gear box 30 in a position fixed to the upper end of the outer post 16. A spacer 42 holds the gearbox 30 and the spindle 28 in a position concentric with the nut 34 and the inner post 14. Thus, in this preferred embodiment, the motor and gear box are located between the seat 60 and the top of the outer post 16.
The seat 60 is secured to the assembly with a seat swivel 50. The seat swivel is mounted on top of the plate 36. Details of the seat and seat swivel are described below in relation to
Surrounding the lower end of the outer post 16 is a foot platform 70, comprising a pair of platform halves 72 and an under carriage 74. The under carriage 74 engages a sleeve 76 which is secured to the outer surface of the outer post 16. The sleeve 76 also includes an outwardly extending plate 78 which provides vertical support for the foot platform 70. A foot operated remote control device 90, described in greater detail below, is preferably mounted on the platform 70 where it can be easily reached by the angler's foot. The sleeve 76 can be raised along with the platform halves 72 to a position that is higher and closer to the seat 60, if a person with shorter legs prefers to do so. To hold the foot platform at a desired distance below the seat 60, a pin 80 engages a selected hole 82 in the wall of the outer post 16. Details of the platform are described below in relation to
In the preceding description in respect of
Further details of the seat and the seat swivel are illustrated in
Near the rear of the seat 60, a hinge 55 is provided to connect the seat 60 to the plate 53 to allow change of the seat's inclination, which is accomplished by an adjustment nut 56 and spindle 57. The spindle 57 is attached to the underside of a seat plate 62. The seat plate 62, along with a back plate 64 (
The seat 60 includes a seat area 69 which defines a recess 68 on either side of the seat 60, which allows an angler to hold onto the seat with his inner thighs when he chooses to stand up to gain an even more elevated view.
As illustrated in
When pressure P is applied to either side of the assembly, as illustrated in
The electronic transmitter 94 contains a battery, which has to be replaced periodically. This is made easy by removing a retainer spring 102 (
By rotating the spindle 202 through the nut 204, the nut moves in an upward or downward direction (depending on the direction of rotation of the spindle 202), and since the nut 204 is mechanically coupled to an inner tube 208, the inner tube 208 moves up and down with the nut 204. The upper end of the tube 208 is connected to an outer tube 210 through a swivel head 212. The motor 200 is mounted to a motor housing 216, and the motor housing 216 extends to a stanchion tube 214. Thus, the stanchion tube 214 remains stationary, along with the motor housing, when the spindle 202 is rotated. The stanchion tube 214 is equipped with a keyway 218, in which rides a key 220 that is part of the outer tube 210. This way, none of the tubes can rotate while the spindle 202 rotates.
Returning briefly to
As shown in
When both halves of the platform 222 are in place, all extensions 236 are in line, and a set of holes 242 in these extensions line up so that a safety or cotter pin 244 can be installed, preventing an accidental upward tilting of the platform halves, such as for example when someone steps on a platform half at a point between the hinge pins 232 and the center split of the platform. The holes 242 in the upward protrusions 240 of platform 230 accommodate the pins 242. Removing these pins 242 allows the platform halves 222 to be rotated up, as illustrated on the left side of
The principles, preferred embodiment, and mode of operation of the present invention have been described in the foregoing specification. This invention is not to be construed as limited to the particular forms disclosed, since these are regarded as illustrative rather than restrictive. Moreover, variations and changes may be made by those skilled in the art without departing from the spirit of the invention.
